 Item 5.  Other Events.

         Reference is hereby made to the Registrant's Registration Statement on
Form S-3 (File No. 333-21329) filed with the Securities and Exchange Commission
(the "Commission") on February 7, 1997, as amended by Amendment No. 1 thereto
filed with the Commission on February 27, 1997, (collectively, the "Registration
Statement"), pursuant to which the Registrant registered $1,000,000,000
aggregate principal amount of its asset-backed certificates, issuable in various
series, for sale in accordance with the provisions of the Securities Act of
1933, as amended (the "Act"). Reference is also hereby made to the Prospectus
dated March 17, 1997 and the related Prospectus Supplement, dated March 17, 1997
(collectively, the "Prospectus"), which were previously filed with the
Commission pursuant to Rule 424(b)(5), with respect to the Registrant's
Preferred Credit Asset-Backed Certificates, Series 1997-1, consisting of the
following Classes of Certificates (collectively, the "Certificates"): (i) Class
A- 1 Certificates, Class A-2 Certificates, Class A-3 Certificates, Class A-4
Certificates, Class A-5 and Certificates Class A-6 Certificates, (collectively,
the "Offered Certificates"), (ii) Class B Certificates, and (iii) Class RU and
RL Certificates. Only the Offered Certificates were offered by the Prospectus.

         The Certificates represent the entire undivided interest in the Trust
created pursuant to the Pooling and Servicing Agreement dated as of June 1, 1996
(the "Pooling and Servicing Agreement") among Credit Suisse First Boston
Mortgage Securities Corp., as depositor, Preferred Credit Corporation as Seller,
Advanta Mortgage Corp. USA, as Servicer, and Bankers Trust Company, as trustee
(the "Trustee"). On the Closing Date, the corpus of the Trust consisted
primarily of (i) a pool (the "Mortgage Pool") of mortgage loans (together, the
"Initial Mortgage Loans"), (ii) amounts on deposit in a pre-funding account (the
"Pre-Funding Account") and a capitalized interest account held by the Trustee;
and (iii) the certificate insurance policy issued by MBIA Insurance Corporation
(the "Certificate Insurer"). On the Closing Date, cash in the amount of
$50,000,000 (the "Pre-Funding Account Deposit") was deposited in the Pre-
Funding Account in the name of the Trustee. The Pre-Funding Account Deposit was
intended to be used for the purchase of additional mortgage loans satisfying the
criteria specified in the Pooling and Servicing Agreement and subject to the
approval of the Certificate Insurer (the "Subsequent Mortgage Loans") on or
before June 27, 1997 (the "Subsequent Transfer Date").

          On or before the Subsequent Transfer Date, the Trustee, on behalf of
the Trust, and the Sponsor entered into a Subsequent Transfer Instrument, dated
April 24, 1997 (the "Subsequent Transfer Instrument"). Pursuant to the
Subsequent Transfer Instrument, the Trust purchased $47,145,777.14 aggregate
principal balance of Subsequent Mortgage Loans to be included in the Mortgage
Pool.

          The description of the Mortgage Pool in the Prospectus contained
information only with respect to the Initial Mortgage Loans as of the date of
the Prospectus. This Current Report on Form 8-K is being filed to update the
description of the Mortgage Pool contained in the Prospectus and to file copies
of certain final agreements executed in connection with the issuance of the
Certificates.

          The following is a summary of certain terms of the final Mortgage
Pool, which includes the Subsequent Mortgage Loans. The information set forth
below is presented with respect to the Initial Mortgage Loans as of the Cut-off
Date and with respect to the Subsequent Mortgage Loans as of April 1, 1997 (the
"Subsequent Cut-off-Date"). The description of the Mortgage Pool below does not
reflect any payments with respect to the Mortgage Loans received by the Servicer
after the Cut-off Date or the Subsequent Cut-off Date. The final Mortgage Pool
consists of 5,733 Mortgage Loans having an aggregate principal balance of
$206,141,805.05. The Mortgage Loans included in the final Mortgage Pool (by
aggregate Cut-Off Date Principal Balance) will have the characteristics set
forth in the tables below:

         The weighted average Combined Loan-to Value Ratio at the Initial
Mortgage Loans as of the Initial Cut-off Date and the Subsequent Mortgage Loan
as of the Subsequent Cut-off Date is approximately 115.80%. The "Combined
Loan-to-Value Ratio" of a Mortgage Loan is the ratio, expressed as a percentage,
equal to the sum of any outstanding senior liens mortgage balance plus the
original balance of the Mortgage Loan divided by the appraised value of the
Mortgaged Property. In the instance where more than one appraisal was performed
on the subject property, the lesser of the two values was used to determine the
Combined Loan-to-Value Ratio.

                             UNDERWRITING AGREEMENT


Credit Suisse First Boston Corporation
11 Madison Avenue
New York, New York 10010


Dear Sirs:

          I. INTRODUCTION. Credit Suisse First Boston Mortgage Securities Corp.,
a Delaware corporation (the "Depositor"), proposes to form one or more real
estate mortgage investment conduits (each, a "Trust"), which will issue, from
time to time, securities entitled Preferred Credit Asset-Backed Certificates
(the "Certificates") in one or more series (each, a "Series"). Each Certificate
will evidence a fractional, undivided percentage interest or beneficial interest
in a Trust. The property of each Trust may consist primarily of a pool (the
"Mortgage Loan Pool") of fixed rate, closed-end no or low equity mortgage loans
secured primarily by subordinate lien mortgages on residential one- to
four-family properties (the "Mortgage Loans") and certain related property to be
conveyed to the Trust by the Depositor (the "Trust Fund"). The Mortgage Loans
may be sold to the Depositor pursuant to one or more Sale and Purchase
Agreements, dated as set forth in the applicable Terms Agreement (as hereinafter
defined) (each, a "Sale and Purchase Agreement"), between the Depositor, as
purchaser, and Preferred Credit Corporation, as Seller (the "Seller"). The
Certificates of any Series will be issued pursuant to a Pooling and Servicing
Agreement to be dated as set forth in the applicable Terms Agreement (the
"Pooling and Servicing Agreement" and, together with this Agreement and the
related Sale and Purchase Agreement, the "Agreements"), among the Depositor, a
servicer (the "Servicer") named in such Terms Agreement and a trustee (the
"Trustee") named in such Terms Agreement.

          The Certificates are more fully described in the Registration
Statement (as such term is defined in Section 2(a)), which the Depositor has
furnished to you. Each Series of Certificates and any classes or subclasses of
Certificates (each, a "Class" or "Subclass", respectively) within such Series
may vary, among other things, as to number and types of Classes or Subclasses,
aggregate principal balance or notional amount or aggregate stated principal
balance, the pass- through rate with respect to each Class or Subclass, the
percentage interest if any, evidenced by each Class or Subclass in payments of
principal and interest on, or with respect to, the Mortgage Loans included in
the related Trust Fund, the stated principal balance and interest rate, if any,
priority of payment among Classes or Subclasses, the method of credit
enhancement with respect to the Mortgage Loans in the Trust Fund for such
Series, the Classes or Subclasses of Certificates of such Series subject to this
Agreement, and any other variable terms contemplated by the Pooling and
Servicing Agreement and in the Certificates of such Series. The Depositor will
elect to treat the related Trust Fund as a "real estate mortgage investment
conduit" (a "REMIC") under the Internal Revenue Code of 1986, as amended (the
"Code").

          Each offering of Certificates will be made through you, through you
and other underwriters for whom you are acting as representative or through an
underwriting syndicate managed by you. Whenever the Depositor determines to form
a Trust and to make such an offering of Certificates, it will enter into an
agreement (the "Terms Agreement") providing for the sale of such Certificates
to, and the purchase and offering thereof by, (i) you, (ii) you and such other
underwriters who execute the Terms Agreement and agree thereby to become
obligated to purchase Certificates from the Depositor, or (iii) you and such
other underwriters, if any, selected by you as have authorized you to enter into
such Terms Agreement on their behalf (in each case, the "Underwriters"). Such
Terms Agreement shall specify the fractional undivided interest, principal or
notional amount, or stated principal balance, of each Class or Subclass of the
Certificates to be issued and their terms not otherwise specified in the Pooling
and Servicing Agreement, the Classes or Subclasses of Certificates subject to
this Agreement, the price at which such Certificates are to be purchased by the
Underwriters from the Depositor, the aggregate amount of Certificates to be
purchased by each Underwriter and any other Underwriter that is a party to such
Terms Agreement and the initial public offering price or the method by which the
price at which such Certificates are to be sold will be determined. The Terms
Agreement, which shall be substantially in the form of Exhibit A hereto, which
may take the form of an exchange of any standard form of written
telecommunication between you and the Depositor. Each offering of Certificates
will be governed by this Agreement, as supplemented by the applicable Terms
Agreement, and this Agreement and such Terms Agreement shall inure to the
benefit of and be binding upon the related Underwriters. Except as otherwise
required by the context, all references herein to a Terms Agreement, Delivery
Date, Pooling and Servicing Agreement and Underwriters shall refer to the Terms
Agreement, Delivery Date, Pooling and Servicing Agreement and Underwriter or
Underwriters, as the case may be, relating to the related Series of
Certificates.

          II. REPRESENTATIONS AND WARRANTIES OF THE DEPOSITOR. The Depositor
represents and warrants to the Underwriters as of the date hereof and as of the
date of the applicable Terms Agreement, as follows:

              (a) A registration statement on Form S-3 (No. 333-21329),
         including a prospectus and such amendments thereto as may have been
         required to the date hereof, relating to the Certificates and the
         offering of each Series thereof from time to time in accordance with
         Rule 415 under the Securities Act of 1933, as amended (the "Act"), has
         been filed with the Securities and Exchange Commission (the
         "Commission") and such registration statement, as amended, has become
         effective. For purposes of this Agreement, "Effective Time" means the
         date and time as of which such registration statement, or the most
         recent post-effective amendment thereto (if any) filed prior to the
         execution and delivery of this Agreement, was declared effective by the
         Commission and "Effective Date" means the date of the Effective Time.
         Such registration statement, as amended, and the prospectus and related
         prospectus supplement that the Depositor has filed with the Commission
         pursuant to Rule 424(b) relating to the sale of the Certificates of the
         applicable Series offered thereby constituting a part thereof, as from
         time to time amended or supplemented (including any prospectus relating
         to the Certificates filed with the Commission pursuant to Rule 424(b)
         of the rules and regulations of the Commission promulgated under the
         Act (the "Rules and Regulations")), including all documents
         incorporated therein by reference relating to the Series of
         Certificates to which the Terms Agreement relates, are respectively
         referred to as the "Registration Statement" and the "Base Prospectus";
         provided, however, that a supplement to such Base Prospectus prepared
         pursuant to Section 5(a) shall be deemed to have supplemented the Base
         Prospectus only with respect to the offering of the Series of
         Certificates to which it relates (any such supplement for a Series of
         Certificates, together with the Base Prospectus, the "Prospectus"). The
         conditions to the use of a registration statement on Form S-3 under the
         Act, as set forth in the General Instructions to Form S-3, and the
         conditions of Rule 415 under the Act, have been satisfied with respect
         to the Registration Statement.

              (b) The Registration Statement, on the Effective Date, and the
         Base Prospectus, as of the date of the related Prospectus conformed in
         all material respects to the requirements of the Act and the Rules and
         Regulations, and did not include any untrue statement of a material
         fact or omit to state any material fact required to be stated therein
         or necessary to make the statements therein not misleading, and on the
         date of this Agreement, at the time of the filing of the Prospectus for
         the Series of Certificates identified in the related Terms Agreement,
         pursuant to Rule 424(b) and at the Delivery Date (as such terms are
         defined in Section 3), such Base Prospectus conforms and will conform
         in all material respects to the requirements of the Act and the Rules
         and Regulations, and does not include and will not include, any untrue
         statement of a material fact and does not omit and will not omit to
         state any material fact necessary in order to make the statements
         therein, in the light of the circumstances under which they were made,
         not misleading. The Prospectus delivered to the Underwriters for use in
         connection with the offering of the related Series of Certificates was
         identical to the electronically transmitted copies thereof filed with
         the Commission pursuant to its Electronic Data Gathering, Analysis and
         Retrieval system, except to the extent permitted by Regulation S-T. The
         two immediately preceding sentences do not apply to statements or
         omissions from either of such documents based upon written information
         (including Computational Materials (as such term is defined in Section
         8(a)) furnished to the Depositor by any Underwriter specifically for
         use therein.

              (c) The Depositor has been duly organized and is validly existing
         as a corporation in good standing under the laws of the State of
         Delaware, with full corporate power and authority to own its assets and
         conduct its business as described in the Prospectus, is duly qualified
         as a foreign corporation in good standing in all jurisdictions in which
         the ownership or lease of its property or the conduct of its business
         requires such qualification, except where the failure to be so
         qualified would not have a material adverse effect on the Depositor,
         and is conducting its business so as to comply in all material respects
         with the applicable statutes, ordinances, rules and regulations of the
         jurisdictions in which it is conducting business.

              (d) The Pooling and Servicing Agreement and the related
         Certificates conform, or will conform as of the related Delivery Date,
         to the description thereof contained in the Registration Statement and
         the related Prospectus; and the Certificates of a Series, on the
         Delivery Date set forth in the related Terms Agreement, will have been
         duly and validly authorized and, when such Certificates are duly and
         validly executed by the Depositor or the Trustee, authenticated by the
         Trustee and delivered in accordance with such Pooling and Servicing
         Agreement and delivered and paid for as provided herein, will be
         validly issued and outstanding and entitled to the benefits afforded by
         the Pooling and Servicing Agreement.

              (e) The execution and delivery by the Depositor of this Agreement,
         the related Terms Agreement, the related Pooling and Servicing
         Agreement and the Certificates of the related Series are within the
         corporate power of the Depositor and have been, or will have been on
         the related Delivery Date, duly authorized by all necessary corporate
         action on the part of the Depositor; and neither the execution and
         delivery by the Depositor of such instruments, nor the consummation by
         the Depositor of the transactions herein or therein contemplated, nor
         the compliance by the Depositor with the provisions hereof or thereof,
         will (i) conflict with or result in a breach of, or constitute a
         default under, any of the provisions of the certificate of
         incorporation or by-laws of the Depositor, (ii) conflict with any of
         the provisions of any law, governmental rule, regulation, judgment,
         decree or order binding on the Depositor or its properties, (iii)
         conflict with any of the provisions of any indenture, mortgage,
         contract or other instrument to which the Depositor is a party or by
         which it is bound, or (iv) result in the creation or imposition of any
         lien, charge or encumbrance upon any of its property pursuant to the 
         terms of any such indenture, mortgage, contract or other instrument.

              (f) At the date thereof, the Pooling and Servicing Agreement will
         constitute a legal, valid and binding obligation of the Depositor,
         enforceable against the Depositor in accordance with its terms,
         subject, as to enforcement of remedies, to applicable bankruptcy,
         reorganization, insolvency, moratorium and other similar laws affecting
         creditors' rights generally from time to time in effect, and to general
         principles of equity.

              (g) All approvals, authorizations, consents, orders or other
         actions of any person, corporation or other organization, or of any
         court, governmental agency or body or official (except with respect to
         the state securities or Blue Sky laws of various jurisdictions),
         required in connection with the valid and proper authorization,
         issuance and sale of the Certificates of the related Series pursuant to
         this Agreement, the Terms Agreement and the Pooling and Servicing
         Agreement, has been or will be taken or obtained on or prior to the
         applicable Delivery Date.

               (h) The Reserve Fund, if any, will be established in accordance
         with the Pooling and Servicing Agreement on or prior to the Delivery
         Date; and a UCC-1 financing statement with respect to such Reserve Fund
         naming the Trustee, for the benefit of the holders of the Certificates,
         as the secured party has been filed in the office of the Secretary of
         State of the state in which the principal trust office of the Trustee
         is located and, upon the purchase by you of the Certificates subject to
         this Agreement in the manner contemplated by this Agreement, and the
         initial deposit of any amount required to be deposited therein pursuant
         to the Pooling and Servicing Agreement, the Trustee, for the benefit of
         the holders of the Certificates will, on the date of such deposit, have
         a first perfected priority security interest in such Reserve Fund.

              (i) At the applicable Delivery Date, each of the Mortgage Loans
         included in the Trust Fund will meet the criteria for selection
         described in the related Prospectus, and will conform to the
         representations and warranties with respect thereto set forth in the
         related Pooling and Servicing Agreement.

              (j) Certificates subject to this Agreement and offered by means of
         the Registration Statement will, when issued pursuant to the Pooling
         and Servicing Agreement, not be "mortgage related securities", as such
         term is defined in Section 3(a)(41) of the Securities Act of 1934, as
         amended (the "Exchange Act").

              (k) No Pooling and Servicing Agreement relating to a Series of
         Certificates will be required to be qualified under the Trust Indenture
         Act of 1933, as amended.

              (l) The characteristics of the Trust Fund will not subject the
         related Trust to registration as an investment company under the
         Investment Company Act of 1940, as amended (the "Investment Company
         Act").

          III. PURCHASE, SALE AND DELIVERY OF CERTIFICATES. Delivery of and
payment for each Series of Certificates to which this Agreement applies will be
made at the office of Credit Suisse First Boston Corporation, 11 Madison Avenue,
New York, New York 10010 or such other place as specified in the Terms
Agreement, at such time as shall be specified in the Terms Agreement, or at such
other time thereafter as set forth in the Terms Agreement, or as you and the
Depositor shall agree upon, each such time being herein referred to as a
"Delivery Date". Delivery of such Certificates shall be made by the Depositor to
the Underwriters against payment of the purchase price specified in the
applicable Terms Agreement in same day funds wired to such bank as may be
designated by the Depositor, or by such other manner of payment as may be agreed
upon by the Depositor and you. Except as otherwise provided in the related Terms
Agreement, each Class of Certificates of a Series sold to the Underwriters
pursuant to such Terms Agreement will be represented initially by one or more
certificates registered in the name of Cede & Co., the nominee of the Depository
Trust Company (the "DTC Certificates"). The interests of the beneficial owners
of the DTC Certificates will be represented by book entries on the records of
DTC and participating members thereof. Definitive certificates for the DTC
Certificates will be made available only under the limited circumstances
specified in the Pooling and Servicing Agreement. Except as otherwise provided
in the related Terms Agreement, each Class of Certificates of a Series not sold
to the Underwriters pursuant to such Terms Agreement will be in definitive,
fully registered form, in such denominations and registered in such names as you
shall request, and will be made available at least 24 hours prior to the
applicable Closing Date, for checking and packaging at the offices of Stroock &
Stroock & Lavan LLP, 180 Maiden Lane, New York, New York 10038 in such amounts
as determined pursuant to the Terms Agreement.

          Except as otherwise provided in the related Terms Agreement, pursuant
to Rule 15c6-l(d) under the Exchange Act, the Depositor and the Underwriters
have agreed that the Delivery Date will not be less than five business days
following the date hereof.

          IV. OFFERING BY UNDERWRITERS. It is understood that the Underwriters
propose to offer the Certificates subject to this Agreement for sale to the
public as set forth in the Prospectus.

          V. COVENANTS OF THE DEPOSITOR. The Depositor covenants and agrees with
the Underwriters participating in the offering of the applicable Series of
Certificates that:

          (a) Immediately following the execution of the Terms Agreement, the
Depositor will prepare a supplement to the Base Prospectus setting forth the
amount of Certificates of the related Series covered thereby and the terms
thereof not otherwise specified in the Base Prospectus, the price at which such
Certificates are to be purchased by the Underwriters, from the Depositor, either
the initial public offering price or the method by which the price at which such
Certificates are to be sold will be determined, the selling concessions and
reallowances, if any, and such other information as you and the Depositor deem
appropriate in connection with the offering of such Certificates, but the
Depositor will not file, for so long as the delivery of a Prospectus is required
in connection with the offering or sale of such Certificates, any amendments to
the Registration Statement as in effect with respect to such Certificates, or
any amendments or supplements to the related Prospectus, unless it shall first
have delivered copies of such amendments or supplements to you, or if you shall
have reasonably objected thereto promptly after receipt thereof, the Depositor
will, during such period, immediately advise you or your counsel (i) when notice
is received from the Commission that any post- effective amendment to the
Registration Statement has become or will become effective and (ii) of any order
or communications suspending or preventing, or threatening to suspend or
prevent, the offer and sale of the Certificates or of any proceedings or
examinations that may lead to such an order or communication, whether by or of
the Commission or any authority administering any state securities or Blue Sky
law, as soon as the Depositor is advised thereof, and will use its best efforts
to prevent the issuance of any such order or communication and to obtain as soon
as possible its lifting, if issued. Subject to the Underwriters' compliance with
their obligations set forth in Section 8, the Depositor shall file with the
Commission a current report on Form 8-K including any Computational Materials
provided to it by the Underwriters pursuant to Section 8 no later than the date
that the related Prospectus is filed with the Commission.

              (b) If, at any time when a Prospectus relating to the Certificates
         of the related Series is required to be delivered under the Act, any
         event occurs as a result of which the Prospectus as then amended or
         supplemented would include any untrue statement of a material fact or
         omit to state a material fact necessary in order to make the statements
         therein, in the light of the circumstances under which they were made,
         not misleading, or if it is necessary at any time to amend or
         supplement the Prospectus to comply with the Act or the Rules and
         Regulations, the Depositor will promptly prepare and file with the
         Commission, an amendment or supplement that will correct such statement
         or omission or an amendment that will effect such compliance.

              (c) The Depositor will make generally available to the holders of
         the Certificates (the "Certificateholders"), and deliver to you, in
         each case as soon as practicable, an earnings statement which will
         satisfy the provisions of Section ll(a) of the Act and Rule 158 of the
         Commission with respect to the Certificates; and the Depositor will
         cause the Trustee to furnish or make available, within a reasonable
         time after the end of each calendar year, to each holder of a
         Certificate at any time during such year, such information as the
         Depositor deems necessary or desirable to assist Certificateholders in
         preparing their federal income tax returns.

              (d) The Depositor will furnish to you copies of the Registration
         Statement (two of which will be signed and will include all documents
         and exhibits thereto or incorporated by reference therein), each
         related preliminary prospectus, the Prospectus and all amendments and
         supplements to such documents relating to the Certificates of the
         related Series, in each case as soon as available, but in no event
         later than five business days after signing the related Terms
         Agreement, and in such quantities as you reasonably request.

              (e) The Depositor will arrange for the qualification
         of the Certificates of the  related Series for sale and the
         determination of their eligibility for investment under the
         laws of such jurisdictions as you designate and will continue such
         qualifications in effect so long as required for the distribution of
         the Certificates; provided, however, that neither the Depositor nor the
         Trust shall be required to do business in any jurisdiction where it is
         now not qualified or to take any action which would subject it to
         general or unlimited service of process in any jurisdiction in which it
         is now not subject to service of process.

              (f) The Depositor will, while the Certificates of a Series are
         outstanding furnish to you, and upon request of each other Underwriter,
         information with respect to the related Trust or the Mortgage Loans
         included in the related mortgage pool, as any Underwriter may
         reasonably request, including but not limited to information necessary
         or appropriate to the maintenance of a secondary market in the
         Certificates of such Series.

              (g) The Depositor will pay all expenses incident to the
         performance of its obligations under this Agreement and the Terms
         Agreement and will reimburse the Underwriters for any expenses
         (including fees and disbursements of its counsel) incurred by them in
         connection with the offering and the qualification of the related
         Series of Certificates and determination of their eligibility for
         investment under the laws of such jurisdictions as you may designate
         and the reproduction of memoranda relating thereto, for any fees
         charged by investment rating agencies for the rating of the
         Certificates and, to the extent previously agreed upon with you, the
         expenses incurred in distributing any preliminary prospectuses, the
         Prospectus or any amendments or supplements thereto to the
         Underwriters.

              (h) During the period when a Prospectus is required by law to be
         delivered in connection with the sale of Certificates of a related
         Series pursuant to this Agreement, the Depositor will file, or cause
         the Trustee to file on behalf of the related Trust, on a timely and
         complete basis, all documents that are required by the related Trust
         with the Commission pursuant to Sections 13, 14 or 15(d) of the
         Exchange Act.

          (i) The Depositor will prepare, or cause to be prepared, and file, or
cause to be filed, a timely election to treat the Trust as a REMIC for federal
income tax purposes and will file, or cause to be filed, such tax returns and
take such actions, all on a timely basis, as are required to elect and maintain
such status.

          VI. CONDITIONS TO THE OBLIGATIONS OF THE UNDERWRITERS. The obligations
of the Underwriters to purchase and pay for the Certificates of a related Series
subject to this Agreement will be subject to the accuracy of the representations
and warranties on the part of the Depositor as of the date hereof, the date of

         be made by the Depositor under the Act prior to the sale of the
         Certificates of the applicable Series shall have been duly taken or
         made; and prior to the applicable Delivery Date, no stop order
         suspending the effectiveness of the Registration Statement shall have
         been issued and no proceedings for that purpose shall have been
         instituted, or to the knowledge of the Depositor or any Underwriter,
         shall be contemplated by the Commission.

              (d) The Certificates subject to this Agreement and offered by
         means of the Registration Statement shall be rated at the time of
         issuance as set forth in the Terms Agreement.

              (e) You shall have received an opinion of counsel or counsels for 
         the Depositor, dated the applicable Delivery Date, substantially to 
         the effect that:

                        (i) The Depositor is a corporation duly organized,
                  validly existing and in good standing under the laws of the
                  State of Delaware, with corporate power and corporate
                  authority to own its assets, operate its business as described
                  in the Prospectus, and is duly qualified to do business as a
                  foreign corporation in the State of New York which the
                  Depositor has advised us in writing are the jurisdictions in
                  which the Depositor owns or leases real property or conducts
                  material operations.

                       (ii)  This Agreement and the Terms Agreement have
                  been duly authorized, executed and delivered by the
                  Depositor.

                       (iii) The execution, delivery and performance of the
                  Agreements do not conflict with the Certificate of
                  Incorporation or the By-laws of the Depositor and, to the
                  knowledge of such counsel and based solely on its examination
                  of the documents referred to herein, (A) do not conflict with
                  or violate or constitute a material breach of, or constitute a
                  default under, any material written contract, indenture,
                  undertaking or other agreement or instrument by which the
                  Depositor is now bound or to which it is now a party, or
                  result in the imposition of any material lien upon any of its
                  material properties, and (B) do not conflict with or violate
                  any order, write, injunction or the decree of any court or
                  governmental authority against the Depositor or by which any
                  of its properties is bound.

                       (iv) Each of the Sale and Purchase Agreement and the
                  Pooling and Servicing Agreement has been duly authorized,
                  executed and delivered by the Depositor and, assuming the due
                  authorization, execution and delivery thereof by the other
                  parties thereto, constitutes the legal, valid and binding
                  agreement of the Depositor, enforceable against the Depositor
                  in accordance with its terms, except as enforcement thereof
                  may be subject to or limited by bankruptcy, insolvency,
                  moratorium, reorganization, arrangement, fraudulent conveyance
                  or other laws relating to or affecting creditors' rights
                  generally or by general equitable principles.

                       (v)  The Certificates of the related Series have
                  been duly authorized by  the Depositor and, when
                  executed and authenticated pursuant to the Pooling and
                  Servicing Agreement and paid for and delivered pursuant to
                  this Agreement and the Terms Agreement, will be validly issued
                  and outstanding and will be entitled to the benefits afforded
                  by the Pooling and Servicing Agreement.

                       (vi) No consent, approval, authorization or order of any
                  court or governmental agency or body is required for the
                  consummation by the Depositor of the transactions contemplated
                  by the Agreements except such as may be required under federal
                  or state securities laws in connection with the purchase by
                  the Underwriters of the Certificates, filings with respect to
                  the transfer of the Mortgage Loans from the Seller to the
                  Depositor pursuant to the Sale and Purchase Agreement and from
                  the Depositor to the Trustee pursuant to the Pooling and
                  Servicing Agreement, which approvals, together with all other
                  necessary approvals, have been obtained.

                       (vii) The Pooling and Servicing Agreement is not required
                  to be qualified under the Trust Indenture Act of 1939 and the
                  Trust Fund is not required to be registered under the
                  Investment Company Act.

                       (viii) The Registration Statement has become effective
                  under the Act, and, to the knowledge of such counsel, no stop
                  order suspending the effectiveness of the Registration
                  Statement has been issued and no proceedings for that purpose
                  have been instituted or are pending or contemplated under the
                  Act; the Registration Statement and the Prospectus, and each
                  amendment or supplement thereto, as of their respective
                  effective or issue dates complied as to form in all material
                  respects to the requirements of the Act and the Rules and
                  Regulations; such counsel has no reason to believe that either
                  the Registration Statement, at the Effective Time, or any such
                  amendment or supplement, as of its effective date, contained
                  any untrue statement of a material fact or omitted to state
                  any material fact required to be stated therein or necessary
                  to make the statements therein not misleading, or that the
                  Prospectus, at the date of this Agreement, or any such
                  amendment or supplement, as of its respective date, or at the
                  Delivery Date, included or includes an untrue statement of a
                  material fact or omitted or omits to state a material fact
                  necessary in order to make the statements therein, in the
                  light of the circumstances under which they were made, not
                  misleading; it being understood that such counsel need express
                  no opinion as to (i) the financial statements or other
                  financial or statistical data contained in the Registration
                  Statement or the Prospectus, including Computational Materials
                  or (ii) any exhibit to the Registration Statement or item
                  incorporated therein by reference which does not relate to the
                  offering of the related Series of Certificates.

                       (ix) The statements in the Prospectus under the caption
                  "Description of Certificates", "Servicing of the Mortgage
                  Loans" and "Description of the Sale and Purchase Agreement"
                  insofar as such statements constitute a summary of certain
                  terms of the Certificates, the Sale and Purchase Agreement and
                  the Pooling and Servicing Agreement, while they do not purport
                  to discuss all aspects of such documents, constitute a fair
                  summary of such documents in all material respects; the
                  statements in the Base Prospectus and/or the Prospectus, as
                  the case may be, under the captions "Certain Aspects of the
                  Mortgage Loans", "ERISA Considerations", "Certain Federal
                  Income Tax Considerations" and "Certain Federal Income Tax
                  Consequences", to the extent that they constitute matters of
                  federal or New York State law or legal conclusions with
                  respect thereto relating to the Mortgage Loans or the
                  Certificates of the related Series, have been prepared or
                  reviewed by us and are correct in all material respects.

              (e) You shall have received an opinion of counsel to the Seller,
         addressed to the Underwriters and the Depositor, dated the applicable
         Delivery Date, substantially to the effect that the statements in the
         Prospectus prepared by the Depositor pursuant to Section 5(a) under the
         captions "The Seller" and "Description of the Mortgage Loans" do not
         contain any untrue statement of a material fact or omit to state a
         material fact required to be stated therein or necessary in order to
         make the statements therein, in the light of the circumstances under
         which they were made, not misleading (it being understood that such
         counsel need not render any opinion with respect to any financial or
         statistical information contained therein).

              (f) You shall have received an opinion of counsel to the Trustee,
         dated the Delivery Date, and in the form agreed to on or prior to the
         date of the Terms Agreement.

              (g) If applicable, you shall have received an opinion of counsel
         to the Servicer, dated the Delivery Date, and in the form agreed to on
         or prior to the date of the Terms Agreement.

              (h) You shall have received from Andrews & Kurth L.L.P., counsel
         for the Underwriters, such opinion or opinions, dated the Delivery
         Date, with respect to the existence of the Depositor, the Registration
         Statement, the Prospectus and other related matters as the Underwriters
         may require, and the Depositor shall have furnished to such
         counsel such documents as they request for the purpose of enabling
         them to pass upon such matters.

              (i) You shall have received a certificate or certificates signed
         by such of the principal executive, financial and accounting officers
         of the Depositor as you may request, dated the applicable Delivery
         Date, in which such officers, to the best of their knowledge after
         reasonable investigation, shall state that (i) the representations and
         warranties of the Depositor in this Agreement are true and correct;
         (ii) the Depositor has complied with all agreements and satisfied all
         conditions on its part to be performed or satisfied at or prior to the
         Closing Date; (iii) no stop order suspending the effectiveness of the
         Registration Statement has been issued and no proceedings for that
         purpose have been instituted or are contemplated; (iv) subsequent to
         the respective dates as of which information is given in the
         Prospectus, and except as otherwise set forth in or contemplated by the

         rating categories established by such agency or agencies as set forth
         in the Terms Agreement and such rating has not been lowered since the
         date of such letter; and (vii) the Reserve Fund, if any, shall have
         been established by the Depositor as contemplated by the Pooling and
         Servicing Agreement.

               (j) If applicable, you shall have received letters dated the
         applicable Delivery Date from counsel rendering opinions to any
         nationally recognized statistical rating organization rating the
         applicable Series of Certificates, to the effect that you may rely upon
         their opinion to such rating organization, as if such opinion were
         rendered to you.

              (k) You shall have received a certificate of the Trustee, signed

     VII. INDEMNIFICATION.

              (a) The Depositor will indemnify and hold harmless each
         Underwriter and each person, if any, who controls such Underwriter
         within the meaning of the Act, against any losses, claims, damages or
         liabilities, joint or several, to which such Underwriter or such
         controlling person may become subject, under the Act or otherwise,
         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
         Registration Statement or the Prospectus or any amendment or supplement
         thereto, or arise out of or are based upon the omission or alleged
         omission to state therein a material fact required to be stated therein
         or necessary to make the statements therein not misleading; and will
         reimburse each Underwriter and each such controlling person for any
         legal or other expenses reasonably incurred by such Underwriter and
         each such controlling person in connection with investigating or
         defending any such loss, claim, damage, liability or action; provided
         however, that the Depositor will not be liable in any such case to the
         extent that any such loss, claim, damage or liability arises out of or
         is based upon any such untrue statement or alleged untrue statement in
         or omission or alleged omission made in any of such documents in
         reliance upon and in conformity with written information furnished to
         the Depositor by the relevant Underwriter specifically for use therein.
         This indemnity agreement will be in addition to any liability which the
         Depositor may otherwise have.

               (b) Each Underwriter will indemnify and hold harmless the
         Depositor, each of its directors, each of its officers who signed the
         Registration Statement and each person, if any, who controls the
         Depositor within the meaning of the Act against any losses, claims,
         damages or liabilities to which the Depositor or any such director,
         officer or controlling person may become subject, under the Act or
         otherwise, insofar as such losses, claims, damages or liabilities (or
         actions in respect thereof) arise of or are based upon any untrue
         statement or alleged untrue statement of any material fact contained in
         the Registration Statement or the Prospectus or any amendment or
         supplement thereto, or arise out of or are based upon the omission or
         the alleged omission to state therein a material fact required to be
         stated therein or necessary to make the statements therein not
         misleading, in each case to the extent, but only to the extent, that
         such untrue statement or alleged untrue statement or omission or
         alleged omission was made in reliance upon and in conformity with
         written information furnished to the Depositor by such Underwriter
         specifically for use therein, and will reimburse any legal or other
         expenses reasonably incurred by the Depositor or any such director,
         officer or controlling person in connection with investigating or
         defending any such loss, claim, damage, liability or action. This
         indemnity agreement will be in addition to any liability that such
         Underwriter may otherwise have. The Depositor acknowledges that, for
         purposes of this Section, the statements set forth in the Prospectus
         Supplement on page S-2 regarding stabilization, in the third paragraph
         under the heading "Underwriting" with respect to the related Series of
         Certificates to be purchased by the Underwriters, constitute the only
         information furnished to the Depositor by the Underwriters for
         inclusion in the Prospectus.

              (c) Promptly after receipt by an indemnified party under this
         Section of notice of the commencement of any action, such indemnified
         party will, if a claim in respect thereof is to be made against the
         indemnifying party under this Section, notify the indemnifying party of
         the commencement thereof; but the omission so to notify the
         indemnifying party will not relieve it from any liability which it may
         have to any indemnified party otherwise in this Section. In case any
         such action is brought against any indemnified party, and it notifies
         the indemnifying party of the commencement thereof, the indemnifying
         party to such indemnified party of its election so to assume the
         defense thereof, the indemnifying party will be entitled to participate
         therein, and, to the extent that it may wish, jointly with any other
         indemnifying party similarly notified, to assume the defense thereof,
         with counsel satisfactory to such indemnified party (who shall not,
         except with the consent of the indemnified party, be counsel to the
         indemnifying party) and, after notice from the indemnifying party to
         such indemnified party of its election so to assume the defense
         thereof, the indemnifying party will not be liable to such indemnified
         party under this Section for any legal or other expenses subsequently
         incurred by such indemnified party in connection with the defense
         thereof other than reasonable costs of investigation.

              (d) If the indemnification provided for in this Section is
         unavailable or insufficient to hold harmless an indemnified party under
         subsection (a) or (b) above, then each indemnifying party shall
         contribute to the amount paid or payable by such indemnified party as a
         result of the losses, claims, damages or liabilities referred to in
         subsection (a) or (b) above (i) in such proportion as is appropriate to
         reflect the relative benefits received by the Depositor on the one hand
         and the Underwriters on the other from the offering of the related
         Series of Certificates or (ii) if the allocation provided by clause (i)
         above is not permitted by applicable law in such proportion as is
         appropriate to reflect not only the relative benefits referred to in
         clause (i) above but also the relative fault of the Depositor on the
         one hand and the Underwriters on the other in connection with the
         statements or omissions which resulted in such losses, claims, damages
         or liabilities as well as any other relevant equitable considerations.
         The relative benefits received by the Depositor on the one hand and the
         Underwriters on the other shall be deemed to be in the same proportion
         as the total net proceeds from the offering (before deducting expenses)
         received by the Depositor bear to the total underwriting discounts and
         commissions received by the Underwriters. The relative fault shall be
         determined by reference to, among other things, whether the untrue or
         alleged untrue statement of a material fact or the omission or alleged
         omission to state a material fact relates to information supplied by
         the Depositor or the Underwriters and the parties' relative intent,
         knowledge, access to information and opportunity to correct or prevent
         such untrue statement or omission. The amount paid by an indemnified
         party as a result of the losses, claims, damages or liabilities
         referred to in the first sentence of this subsection (d) shall be
         deemed to include any legal or other expenses reasonably incurred by
         such indemnified in connection with investigating or defending any
         action or claim which is the subject to this subsection (d).
         Notwithstanding the provisions of this subsection (d), no Underwriter
         shall be required to contribute any amount in excess of the amount by
         which the total price at which the related Series of Certificates
         underwritten by it and distributed to the public were offered to the
         public exceeds the amount of any damages which such Underwriter has
         otherwise been required to pay by reason of such untrue or alleged
         untrue statement or omission or alleged omission. No person guilty of
         fraudulent misrepresentation (within the meaning of Section ll(f) of
         the Act) shall be entitled to contribution from any person who was not
         guilty of such fraudulent misrepresentation. The Underwriters'
         obligations in this subsection (d) to contribute are several in
         proportion to their respective underwriting obligations and not joint.

          VIII. COMPUTATIONAL MATERIALS.

          (a) Each Underwriter agrees to provide to the Depositor no less than
          two business days prior to the date on which the Prospectus is
          proposed to be filed pursuant to Rule 424(b) under the Act, for the
          purpose of permitting the Depositor to comply with the filing
          requirement set forth in Section 5(a), all information (in such
          written or electronic format as required by the Depositor) with
          respect to the related Series of Certificates which constitutes
          "Computational Materials", as defined in the Commission's No-Action
          Letter, dated May 20, 1994, addressed to Kidder, Peabody Acceptance
          Corporation I, Kidder, Peabody & Co. Incorporated and Kidder
          Structured Asset Corporation (the "Kidder Letter"), and that is
          required to be filed as described in the Kidder Letter.

          (b) The relevant Underwriter shall provide to the Depositor, together
          with the information required to be provided to the Depositor pursuant
          to Section 8(a) or 8(c)(iii) hereof, a letter, in form and substance
          acceptable to the Depositor, of independent certified public
          accountants acceptable to the Depositor, stating in effect that such
          independent certified public accountants have performed certain
          specified procedures, all of which have been agreed to by the
          Depositor, and that they have verified or confirmed, as appropriate,
          the financial, numerical or statistical information to be filed by the
          Depositor as part of the Computational Materials and have found such
          information to be accurate without exception. Such letter will be
          obtained at the sole expense of the Underwriters.

          (c) (i) The relevant Underwriter represents and warrants to, and
          covenants with, the Depositor that all information provided to the
          Depositor pursuant to this Section, as of the date such information is
          so provided and as of the date such information is filed by the
          Depositor with the Commission will not include any untrue statement of
          a material fact and will not omit to state any material facts required
          to be stated therein or necessary in order to make the statements
          contained therein, in the light of the circumstances under which they
          were made, not misleading.

                           (ii) The relevant Underwriter further covenants with
          the Depositor that if any Computational Materials required to be
          provided to the Depositor pursuant to Section 8(a) are determined to
          contain any information that is inaccurate or misleading, the relevant
          Underwriter (whether or not such Computational Materials are provided
          to the Depositor or filed by the Depositor with the Commission) shall
          promptly prepare and deliver to the Depositor and each prospective
          investor which received such Computational Materials corrected
          Computational Materials. All information provided to the Depositor
          pursuant to this Section 8(c)(ii) shall be provided within the time
          periods set forth in Section 8(a) hereof.

                           (iii) The Underwriters represent and warrant to the
          Depositor that the Underwriters have taken all necessary and required
          steps to ensure that no written material of any kind relating to a
          given Series of Certificates (or any certificates similar to the
          Certificates) will be delivered to potential investors other than
          Computational Materials required to be filed pursuant to the Kidder
          Letter and that all Computational Materials will be provided to the
          Depositor and to ensure that all such Computational Materials are
          accurate and not misleading.

                           (iv) The Underwriters covenant with the Depositor
          that all Computational Materials delivered to prospective investors
          shall contain a legend substantially to the following effect:

                           "THIS INFORMATION IS FURNISHED TO YOU SOLELY
                           BY  CREDIT SUISSE FIRST BOSTON CORPORATION
                           AND/OR  THE OTHER UNDERWRITERS AND NOT BY
                           CREDIT  SUISSE FIRST BOSTON MORTGAGE
                           SECURITIES CORP.  (THE "DEPOSITOR") OR ANY
                           OF ITS AFFILIATES (OTHER  THAN CREDIT SUISSE
                           FIRST BOSTON CORPORATION IN   ITS CAPACITY
                           AS AN UNDERWRITER). THE  UNDERWRITERS ARE
                           NOT ACTING AS AGENTS FOR THE  DEPOSITOR OR
                           ITS AFFILIATES IN CONNECTION WITH  THE
                           PROPOSED TRANSACTION."

          (d) The relevant Underwriter agrees to indemnify and hold harmless the
          Depositor, each of the Depositor's officers and directors and each
          person who controls the Depositor within the meaning of either the Act
          or the Exchange Act against any and all losses, claims, damages or
          liabilities, joint or several, to which they may become subject under
          the Act, the Exchange Act, or other Federal or State statutory law or
          regulation, at common law or otherwise, insofar as such losses,
          claims, damages or liabilities (or actions in respect thereof) (i) are
          based on, result from or arise of: (A) the relevant Underwriter's use
          or delivery to any prospective investor in the Certificates of any
          Series of any Computational Materials; (B) the relevant Underwriter's
          failure to comply with Sections 8(a) or 8(c); (C) the filing by the
          Depositor with the Commission of any information pursuant to the last
          sentence of Section 5(a); or (ii) arise out of or are based upon any
          untrue statement or alleged untrue statement of a material fact
          contained in any information required to be delivered to the Depositor
          pursuant to a Section 8(a) or 8(c)(ii) hereof, or arise out of or are
          based upon the omission or alleged omission to state therein a
          material fact required to be stated therein or necessary to make the
          statements therein, in the light of the circumstances under which they
          were made, not misleading, and agrees to reimburse each such
          indemnified party for any legal or other expenses reasonably incurred
          by him, her or it in connection with investigating or defending any
          such loss, claim, damage, liability or action. The obligations of such
          Underwriter under this Section shall be in addition to any liability
          which such Underwriter may otherwise have.

          The procedures set forth in Section 7(c) and 7(d) shall be equally
          applicable to this Section.

          (e) Notwithstanding any other provision herein, (a) no Underwriter
          shall be required to be responsible for any amount in excess of the
          amount by which the total re-offering price at which the Certificates
          underwritten by it and distributed and offered to the public exceeds
          the amount paid hereunder by the Underwriter for the Certificates. For
          the purposes of this Section 8(e), each person, if any, who controls
          the Underwriter within the meaning of the Securities Act or the
          Exchange Act shall have the same rights to contribution as the
          Underwriter and each director of the Depositor, each officer of the
          Depositor who signed the Registration Statement, and each person, if
          any, who controls the Depositor within the meaning of the Securities
          Act or the Exchange Act shall have the same rights to contribution as
          the Depositor and (b) the relevant Underwriter agrees to pay all costs
          and expenses of the Depositor incurred in connection with (i) the
          filing by the Depositor of any Computational Material with the
          Commission and (ii) any action by the Depositor against the relevant
          Underwriter to enforce any of its rights set forth in this Section,
          including, without limitation, legal fees and expenses.

          IX. DEFAULT OF UNDERWRITERS. If any Underwriter or Underwriters
participating in an offering of a Series of Certificates default in their
obligations to purchase Certificates of the related Series hereunder and under
the related Terms Agreement and the aggregate principal amount of such
Certificates which such defaulting Underwriter or Underwriters agreed, but
failed, to purchase does not exceed 10% of the total principal amount of the
Certificates set forth in such Terms Agreement, you may make arrangements
satisfactory to the Depositor for the purchase of such Certificates by other
persons, including any of the Underwriters participating in such offering, but
regardless of whether such arrangements are made the non-defaulting Underwriters
shall remain obligated severally to purchase the Certificates of the related
Series which they committed to purchase in accordance with the terms hereunder
and under the Terms Agreement. If any Underwriter or Underwriters so default and
the aggregate principal amount of Certificates of the related Series with
respect to which such default or defaults occur is more than 10% of the total
principal amount of the Certificates set forth in such Terms Agreement and
arrangements satisfactory to you and the Depositor for the purchase of such
Certificates by other persons are not made, this Agreement will terminate
without liability on the part of any nondefaulting Underwriter, except as
provided in Section 10. As used in this Agreement, the term "Underwriter"
includes any person substituted for an Underwriter under this Section. Nothing
herein will relieve a defaulting Underwriter from liability for its default.

          X. TERMINATION OF THE OBLIGATIONS OF THE UNDERWRITERS. The obligations
of the Underwriters to purchase the Certificates of a given Series on the
related Delivery Date shall be terminable by the Underwriters if (a) at any time
on or prior to the Delivery Date (i) trading in securities generally on the New
York Stock Exchange shall have been suspended or materially limited, or there
shall have been any setting of minimum prices for trading on such exchange, (ii)
a general moratorium on commercial banking activities in New York shall have
been declared by either Federal or New York State authorities, (iii) there shall
have occurred any material outbreak or escalation of hostilities or other
calamity or crisis, the effect of which on the financial markets of the United
States is such as to make it, in your judgment as representative of the
Underwriters, impracticable to consummate the transactions contemplated herein
or is such as would materially and adversely affect the marketability of or the
market price for the Certificates or (iv) any change or any development
involving a prospective change, materially and adversely affecting (A) the Trust
Fund taken as a whole or (B) the business or properties of the Depositor occurs,
which, in your reasonable judgment as representative of the Underwriters, in the
case of either clause (A) or (B), materially impairs the investment quality of
the Certificates or (b) any representation or warranty of another party shall be
incorrect in any material respect.

          XI. SURVIVAL OF CERTAIN REPRESENTATIONS AND OBLIGATIONS. The
respective indemnities, agreements, representations, warranties and other
statements by the Depositor or its officers and of the Underwriters set forth in
or made pursuant to this Agreement will remain in full force and effect,
regardless of any investigation, or statement as to the results thereof, made by
or on behalf of the Underwriters, the Depositor or any of its officers or
directors or any controlling person, and will survive delivery of and payment
for Certificates of the related Series.

          If this Agreement is terminated pursuant to Section 9 or if for any
reason the purchase of the Certificates of a given Series by the Underwriters is
not consummated, the Depositor shall remain responsible for the expenses to be
paid or reimbursed by them pursuant to Section 5(g), and the obligations of the
Depositor and the Underwriters pursuant to Sections 7 and 8 shall remain in
effect.

          XII. NOTICES. All communications hereunder will be in writing and, if
sent to an Underwriter will be mailed, delivered or telegraphed and confirmed to
you at 11 Madison Avenue, New York, New York 10010 or if sent the Depositor,
will be mailed, delivered or telegraphed and confirmed to it at 11 Madison
Avenue, New York, New York 10010 Attention: President; provided, however, that
any notice to an Underwriter pursuant to Section 7 or 8 will be mailed,
delivered or telegraphed to such Underwriter at the addressee furnished by it.

          XIII. SUCCESSORS. This Agreement and the Terms Agreement with respect
to a given Series of Certificates will inure to the benefit of and be binding
upon the parties hereto and their respective successors and the officers,
directors and controlling persons referred to in Sections 7 and 8, and their
successors and assigns, and no other person will have any right or obligations
hereunder.

          XIV. REPRESENTATION OF UNDERWRITERS. You will act for the several
Underwriters set forth in the applicable Terms Agreement in connection with the
transactions described in this Agreement and such Terms Agreement with respect
to a given Series of Certificates and any action taken by you under this
Agreement will be binding upon all the Underwriters for such Series of
Certificates.

          XV. APPLICABLE LAW. THIS AGREEMENT WILL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO THE
PRINCIPLES OF CONFLICTS OF LAWS.

          XVI. COUNTERPARTS. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all such
counterparts shall together constitute one and the same instrument.

                           Establishment of the Trust
                      Sale and Conveyance of the Trust Fund

          Section 2.1 SALE AND CONVEYANCE OF TRUST FUND: PRIORITY AND
SUBORDINATION OF OWNERSHIP INTERESTS; ESTABLISHMENT OF THE TRUST. (a) The
Depositor, as of the Closing Date, does hereby sell, transfer, assign, set over
and convey to the Trust Fund, for the benefit of the Certificateholders as their
respective interests may from time to time appear and the Certificate Insurer,
without recourse but subject to the provisions in this Section 2.1 and the other
terms and provisions of this Agreement, all of the right, title and interest of
the Depositor in and to the Trust Fund, exclusive of the obligations of the
Depositor, Seller or any other party with respect to the Mortgage Loans. In
connection with such transfer and assignment, and pursuant to Section 2.07 of
the Sale and Purchase Agreement, the Depositor does hereby also irrevocably
transfer, assign, set over and otherwise convey to the Trustee all of its rights
under the Sale and Purchase Agreement including, without limitation, its right
to exercise the remedies created by Section 3.05 of the Sale and Purchase
Agreement for breaches of representations and warranties, agreements and
covenants of the Seller contained in Sections 3.02 and 3.03 of the related Sale
and Purchase Agreement. Upon receipt of the Certificates in exchange for the
Mortgage Loans, the Depositor shall have hereby relinquished all rights with
respect to the Mortgage Loans, and have no right to sell, pledge, encumber or
otherwise dispose of the Mortgage Loans.

          It is intended that the conveyance of the Mortgage Loans by the
Depositor to the Trustee as provided in this Section 2.1(b) and of the
Subsequent Mortgage Loans and the related property pursuant to Section 2.9 be,
and be construed as, a sale of the Mortgage Loans by the Depositor to the
Trustee for the benefit of the Certificateholders and the Certificate Insurer,
and it is, further, not intended that such conveyance be deemed a pledge of the
Mortgage Loans by the Depositor to the Trustee to secure a debt or other
obligation of the Depositor. However, in the event that the Mortgage Loans are
held to be property of the Depositor or if for any reason this Agreement is held
or deemed to create a security interest in the Mortgage Loans, then it is
intended that, (a) this Agreement shall also be deemed to be a security
agreement within the meaning of Articles 8 and 9 of the New York Uniform
Commercial Code; (b) the conveyance provided for in this Section 2.1 shall be
deemed (1) to be a grant by the Depositor to the Trustee of a security interest
in all of the Depositor's right, title and interest in and to the Mortgage Loans
and all amounts payable to the holders of the Mortgage Loans in accordance with
the terms thereof and all proceeds of the conversion, voluntary or involuntary,
of the foregoing into cash, instruments, securities or other property,
including, without limitation, all amounts from time to time held or invested in
the Certificate Account, the Collection Account, the Pre-Funding Account and the
Capitalized Interest Account, whether in the form of cash, instruments,
securities or other property and (2) an assignment by the Depositor to the
Trustee of any security interest in any and all of the Depositor's right
(including the power to convey title thereto), title and interest, whether now
owned or hereafter acquired, in and to the property described in the foregoing
clause (b) granted by the Seller to the Depositor pursuant to the Sale and
Purchase Agreement; (c) the possession by the Trustee or its agent of Mortgage
Notes and such other items of property as constitute instruments, money,
negotiable documents or chattel paper shall be deemed to be "possession by the
secured party" for purposes of perfecting the security interest pursuant to the
New York Uniform Commercial Code and the Uniform Commercial Code of any other
applicable jurisdiction (including, without limitation, Section 9-305, 8-313 or
8-321 thereof); and (d) notifications to persons holding such property, and
acknowledgments, receipts or confirmations from, financial intermediaries,
bailees or agents (as applicable) of the Trustee shall be made for the purpose
of perfecting such security interest under applicable law. The Depositor and the
Trustee, as directed by the Servicer, the Certificate Insurer or the Depositor,
shall, to the extent consistent with this Agreement, take such actions as may be
necessary to ensure that, if this Agreement were deemed to create a security
interest in the Mortgage Loans, such security interest would be deemed to be a
perfected security interest of first priority under applicable law and will be
maintained as such throughout the term of the Agreement, including the filing by
the Depositor of any financing statements and continuation statements evidencing
such security interest.

          In connection with the sale, transfer, assignment, and conveyance,
from the Depositor to the Trust Fund, the Depositor has filed, or shall cause to
be filed, in the appropriate office or offices in the State of New York, a UCC-1
financing statement executed by the Depositor as debtor, naming the Trustee as
secured party and listing the Mortgage Loans and the other property described
above as collateral. The characterization of the Depositor as a debtor and the
Trustee as the secured party in such financing statements is solely for
protective purposes and shall in no way be construed as being contrary to the
intent of the parties that this transaction be treated as a sale of the
Depositor's entire right, title and interest in the Mortgage Loans to the Trust
Fund. In connection with such filing, the Depositor agrees that it shall cause
to be filed all necessary continuation statements thereof and to take or cause
to be taken such actions and execute such documents as are necessary to perfect
and protect the Trustee's, the Certificateholders' and the Certificate Insurer's
interests in the Mortgage Loans.

          (b) The rights of the Certificateholders to receive payments with
respect to the Mortgage Loans in respect of the Certificates, and all ownership
interests of the Certificateholders, in such payments, shall be as set forth in
this Agreement. In this regard, all rights of the Class B Certificateholders and
the Residual Certificateholders to receive payments in respect of the Class B
Certificates and the Residual Certificates, respectively, are subject and
subordinate to the preferential rights of the Class A Certificateholders to
receive payments in respect of the Class A Certificates and to the Certificate
Insurer's rights to be reimbursed for Insured Payments together with interest
thereon at the rate specified in the Certificate Insurance Agreement. In
accordance with the foregoing, the ownership interest of the Class B
Certificateholders and the Residual Certificateholders in amounts deposited in
the Certificate Account, the Collection Account, the Pre-Funding Account or the
Capitalized Interest Account from time to time shall not vest unless and until
such amounts are distributed in respect of the Class B Certificates and the
Residual Certificates in accordance with the terms of this Agreement.

          Section 2.2 POSSESSION OF MORTGAGE FILES; ACCESS TO MORTGAGE FILES.
(a) Upon the issuance of the Certificates, the ownership of each Mortgage Note,
the Mortgage and the contents of the related Mortgage File related to each
Mortgage Loan is vested in the Trustee for the benefit of the Certificateholders
and the Certificate Insurer, as their respective interests may, from time to
time, appear.

          (b) The Trustee shall or cause to afford the Depositor, the
Certificate Insurer and the Servicer reasonable access to all records and
documentation regarding the Mortgage Loans relating to this Agreement, such
access being afforded at customary charges, upon reasonable request and during
normal business hours at the offices of the Trustee.

          Section 2.3 DELIVERY OF MORTGAGE LOAN DOCUMENTS. (a) In connection
with each conveyance pursuant to Section 2.1 or 2.9 hereof, the Depositor has
delivered or does hereby agree to deliver or cause to be delivered to the
Trustee the Certificate Insurance Policy and each of the following documents for
each Mortgage Loan sold by the Seller to the Depositor and sold by the Depositor

                           Property is  located, in the name of the Seller
                           signed by an authorized officer of the  Seller

                           relates to the Trustee's Mortgage File if the

                           Certificate Insurer stating that, in such counsel's
                           opinion, the failure to record such Assignment of
                           Mortgage shall not have a materially adverse effect 
                           on the security interest of the Trustee in the 
                           Mortgage; provided, FURTHER, that any Assignment of

such transfer, in lieu of delivering such original documents, the Depositor is
delivering to the Trustee a true copy thereof with a certification by the Seller

Closing Date; PROVIDED, HOWEVER, that in those instances where the public
recording office retains the original Mortgage or Assignment of Mortgage after
it has been recorded or such original document has been lost by the recording

Assignment of Mortgage certified by the public recording office to be a true
copy of the recorded original thereof. The Seller agrees, at its own expense, to

direction and expense, shall also complete each Assignment of Mortgage with
respect to each Mortgage Loan conveyed on the Closing Date such that the final
Assignment of Mortgage appears in the following form:

          "Bankers Trust Company, as Trustee for the benefit of the
Certificateholders and the Certificate Insurer for Preferred Credit Asset Backed
Certificates Series 1997-1."

          (c) In the event that any Mortgage Note required to be delivered
pursuant to this Section 2.3 is conclusively determined by any of the Seller,
the Servicer or the Trustee to be lost, stolen or destroyed the Seller shall,
within 14 days of the Closing Date, deliver to the Trustee a "lost note
affidavit" in form and substance acceptable to the Trustee, and shall
simultaneously therewith request the obligor on such Mortgage Note to execute
and return a replacement Mortgage Note, and shall further agree to hold the
Trustee and the Certificate Insurer harmless from any loss or damage resulting
from any action taken in reliance on the delivery and possession by the Trustee
of such lost note affidavit. Upon the receipt of such replacement Mortgage Note,
the Trustee shall return the lost note affidavit. Delivery by the Seller of such
lost note affidavit shall not affect the obligations of the Seller hereunder
with respect to the related Mortgage Loan.

          (d) Promptly after the Closing Date, the Seller shall, with respect to
each Mortgage Loan, cause to be recorded in the appropriate public office for
real property records, where permitted by applicable law and where applicable
law does not require that a subordinate mortgagee be named as a party defendant
in foreclosure or comparable proceedings in order to foreclose or otherwise
preempt such mortgagee's equity of redemption, a request for notice of any
action by or on behalf of any mortgagee under the related senior lien.

          Section 2.4 ACCEPTANCE BY TRUSTEE OF THE TRUST FUND; CERTAIN
SUBSTITUTIONS; CERTIFICATION BY TRUSTEE. (a) The Trustee agrees to execute and
deliver to the Depositor, the Certificate Insurer, the Servicer and the Seller
on or prior to the Closing Date an acknowledgment of receipt of the related
Certificate Insurance Policy and, with respect to each Mortgage Loan, the
original Mortgage Note (with any exceptions noted), in the form attached as
Exhibit D hereto and declares that it will hold such documents and any
amendments, replacements or supplements thereto, as well as any other assets
included in the definition of Trust Fund and delivered to the Trustee, as
Trustee in trust upon and subject to the conditions set forth herein for the
benefit of the Certificateholders and the Certificate Insurer. The Trustee
agrees, for the benefit of the Certificateholders and the Certificate Insurer,
to review (or cause to be reviewed) each Trustee's Mortgage File prior to the
Closing Date (with respect to the Mortgage Loans) and to deliver to the Seller,
the Servicer, the Depositor and the Certificate Insurer a certification in the
form attached hereto as Exhibit E to the effect that, as to each Mortgage Loan
listed in the related Mortgage Loan Schedule (other than any Mortgage Loan paid
in full or any Mortgage Loan specifically identified in such certification as
not covered by such certification), (i) all Mortgage Notes required to be
delivered to it pursuant to Section 2.3(a)(i) hereof are in its possession, (ii)
each such Mortgage Note has been reviewed by it, has been, to the extent
required, executed and has not been mutilated, damaged, torn or otherwise
physically altered (handwritten additions, changes or corrections shall not
constitute physical alteration if initialed by the Mortgagor), appears regular
on its face and relates to such Mortgage Loan. The Trustee shall be 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 are other
than what they purport to be on their face.

          Within thirty (30) days after the Closing Date and within thirty (30)
days of receipt of a Subsequent Mortgage Loan or Qualified Substitute Mortgage
Loan, the Trustee shall deliver (or cause to be delivered) to the Servicer, the
Seller, the Depositor and the Certificate Insurer a final certification in the
form attached hereto as Exhibit F to the effect 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 such certification as not
covered by such certification), and as to any document noted as an exception
included in the Trustee's initial certification, (i) all documents required to
be delivered to it pursuant to Section 2.3 hereof are in its possession, (ii)
each such document has been reviewed by it, has been, to the extent required,
executed and has not been mutilated, damaged, torn or otherwise physically
altered (handwritten additions, changes or corrections shall not constitute
physical alteration if initialed by the Mortgagor), appears regular on its face
and relates to such Mortgage Loan.

          (b) If the Certificate Insurer or the Trustee during the process of
reviewing the Trustee's Mortgage Files finds any document constituting a part of
a Trustee's Mortgage File which is not executed, has not been received, is
unrelated to the Mortgage Loan identified in the related Mortgage Loan Schedule,
or does not conform to the requirements of Section 2.3 or the description
thereof as set forth in the related Mortgage Loan Schedule, the Trustee or the
Certificate Insurer, as applicable, shall promptly so notify the Servicer, the
Seller, the Depositor, the Certificate Insurer and the Trustee. In performing
any such review, the Trustee may conclusively rely on the Seller as to the
purported genuineness of any such document and any signature thereon. It is
understood that the scope of the Trustee's review of the Mortgage Files is
limited solely to confirming that the documents listed in Section 2.3 have been
executed and received and relate to the Mortgage Files identified in the related
Mortgage Loan Schedule. The Seller agrees to use reasonable efforts to cause to
be remedied a material defect in a document constituting part of a Mortgage File
of which it is so notified by the Trustee. If, however, within 60 days after the
Trustee's notice to it respecting such defect the Seller has not caused to be
remedied the defect and the defect materially and adversely affects the interest
of the Certificateholders in the related Mortgage Loan or the interests of the
Certificate Insurer, the Trustee shall enforce the Seller's obligation to either
(i) substitute in lieu of such Mortgage Loan a Qualified Substitute Mortgage
Loan in the manner and subject to the conditions set forth in Section 3.4 hereof
or (ii) purchase such Mortgage Loan at a purchase price equal to the outstanding
Principal Balance of such Mortgage Loan as of the date of purchase, plus the
greater of (x) all accrued and unpaid interest thereon and (y) 30 days' interest
thereon, computed at the related Mortgage Interest Rate, plus the amount of any
unpaid and accrued Servicing Fees, any unreimbursed Delinquency Interest
Advances and Servicing Advances made by the Servicer with respect to such
Mortgage Loan, which purchase price shall be deposited in the Collection Account
prior to the next succeeding Servicer Remittance Date, after deducting therefrom
any amounts received in respect of such repurchased Mortgage Loan or Loans and
being held in the Collection Account for future distribution to the extent such
amounts have not yet been applied to principal or interest on such Mortgage Loan
(the "Loan Repurchase Price"); PROVIDED, HOWEVER, that the Seller may not,
pursuant to clause (ii) preceding, purchase the Principal Balance of any
Mortgage Loan that is not in default or as to which no default is imminent
unless the Seller has theretofore delivered an Opinion of Counsel knowledgeable
in federal income tax matters which states that such a purchase would not
constitute a prohibited transaction under the Code.

          (c) Upon receipt by the Trustee of a certification of a Servicing
Officer of such substitution or purchase and, in the case of a substitution,
upon receipt of the related Trustee's Mortgage File for the applicable Qualified
Substitute Mortgage Loan or Loans, and the deposit of the amounts described
above into the Collection Account (which certification shall be in the form of
Exhibit G hereto), the Trustee shall release to the Servicer for release to the
Seller the related Trustee's Mortgage File and shall execute, without recourse,
and deliver such instruments of transfer furnished by the Seller as may be
necessary to transfer such Mortgage Loan to the Seller. The Trustee shall
promptly notify the Certificate Insurer if the Seller fails to repurchase or
substitute for a Mortgage Loan in accordance with the foregoing.

          Section 2.5 [RESERVED] .

          Section 2.6 EXECUTION OF CERTIFICATES. The Trustee acknowledges the
assignment to it of the Mortgage Loans and the delivery to it of the Trustee's
Mortgage Files relating thereto and, concurrently with such delivery, has
executed, authenticated and delivered to or upon the order of the Depositor, in
exchange for the Mortgage Loans, the Trustee's Mortgage Files and the other
assets included in the definition of Trust Fund, Certificates duly authenticated
by the Trustee, in Authorized Denominations, evidencing the entire beneficial
ownership interest in the Trust Fund.

          Section 2.7 APPLICATION OF PRINCIPAL AND INTEREST. In the event that
Net Liquidation Proceeds on a Liquidated Mortgage Loan are less than the
outstanding Principal Balance of the related Mortgage Loan plus accrued interest
thereon, or any Mortgagor makes a partial payment of any Monthly Payment due on
a Mortgage Loan, such Net Liquidation Proceeds or partial payment shall be
applied to payment of the related Mortgage Note as provided therein, and if not
so PROVIDED, first to interest accrued at the Mortgage Interest Rate, then to
the principal owed on such Mortgage Loan.

          Section 2.8 FURTHER ASSURANCES; POWERS OF Attorney. (a) The Depositor
and the Servicer shall take no action inconsistent with the Trust's ownership of
the Trust Fund and shall indicate or shall cause to be indicated in its records
and records held on its behalf that ownership of each Mortgage Loan and the
assets in the Trust Fund are held by the Trustee on behalf of the Trust Fund. In
addition, the Depositor and the Servicer shall respond to any inquiries from
third parties with respect to ownership of a Mortgage Loan or any other asset in
the Trust Fund by stating that it is not the owner of such asset and that
ownership of such Mortgage Loan or other Trust Fund asset is held by the Trustee
on behalf of the Trust Fund.

          (b) The Servicer agrees that, from time to time, at the Seller's
expense, it shall cause the Seller (and the Depositor also agrees that it
shall), promptly to execute and deliver all further instruments and documents,
and take all further action, that may be necessary or appropriate, or that the
Servicer or the Trustee or the Certificate Insurer may reasonably request, in
order to perfect, protect or more fully evidence the transfer of ownership of
the Trust Fund or to enable the Trustee to exercise or enforce any of its rights
hereunder. Without limiting the generality of the foregoing, the Servicer, the
Seller and the Depositor will, upon the request of the Servicer or of the
Trustee execute and file (or cause to be executed and filed) such real estate
flings, financing or continuation statements, or amendments thereto or
assignments thereof, and such other instruments or notices, as may be necessary
or appropriate.

          (c) The Depositor hereby grants to the Servicer and the Trustee powers
of attorney to execute all documents on its behalf under this Agreement as may
be necessary or desirable to effectuate the foregoing.

          Section 2.9 CONVEYANCE OF THE SUBSEQUENT MORTGAGE LOANS. (a) Subject
to the conditions set forth in Section 2.3 above and paragraph (b) below in
consideration of the Trustee's delivery on the related 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 Trustee
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 on and after the related Subsequent Cut-Off Date and (iii) all
items with respect to such Subsequent Mortgage Loans to be delivered pursuant to
Section 2.3 above 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
by the Depositor of the Subsequent Mortgage Loans identified on the Mortgage
Loan Schedule shall be absolute and is intended by the Depositor, the 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 three Business Days (or such shorter period as may be agreed between the
Depositor and the Trustee) prior to the Subsequent Transfer Date.

          The purchase price paid by the Trustee from amounts released from the
Pre- Funding Account shall be 97% of the aggregate Principal Balances as of the
related Subsequent Cut-Off Date of the Subsequent Mortgage Loans so transferred.
This Agreement shall constitute a fixed-price purchase contract in accordance
with Section 860G(a)(3)(A)(ii) of the Code.

          (b) The Depositor shall transfer to the Trustee the Subsequent
Mortgage Loans and the other property and rights related thereto described in
Section 2.9 (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
                           Certificate Insurer no later than five Business Days
                           prior to the Subsequent Transfer Date an Addition
                           Notice and shall have provided any information
                           reasonably requested by the Trustee or the
                           Certificate Insurer with respect to the Subsequent
                           Mortgage Loans;

                           shall not be insolvent nor shall it have been made
                           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;

                           following and in the related Subsequent Transfer
                           Instrument;

                  (viii)   the Depositor shall have delivered to the

                           equity or at law);

                  (iv)     No consent, approval, authorization or order of,
                           or registration or filing  with, or notice to,
                           any governmental authority or court is required
                           for the  execution, delivery and performance of
                           or compliance by the Depositor  with this
                           Agreement or the consummation by the Depositor of
                           any of the  transactions contemplated hereby,
                           except as have been received or  obtained on or
                           prior to the Closing Date;

                   (v)     None of the execution and delivery of this
                           Agreement, the consummation  of the transactions
                           contemplated hereby or thereby, or the
                           fulfillment of or  compliance with the terms and
                           conditions of this Agreement, (a) conflicts  or
                           will conflict with or results or will result in a
                           breach of, or constitutes or  will constitute a
                           default or results or will result in an
                           acceleration (I) under  the charter or bylaws of
                           the Depositor, or (II) of any term, condition or
                           provision of any material indenture, deed of
                           trust, contract or other  agreement or instrument
                           to which the Depositor or any of its subsidiaries
                           is a party or by which it or any of its subsidiaries
                           is bound; (b) results or will result in a violation
                           of any law, rule, regulation, order, judgment or
                           decree applicable to the Depositor of any court or
                           governmental authority having jurisdiction over the
                           Depositor or its subsidiaries; or (c) results in the
                           creation or imposition of any lien, charge or
                           encumbrance which would have a material adverse
                           effect upon the Mortgage Loans or any documents or
                           instruments evidencing or securing the Mortgage
                           Loans;

                  (vi)     There are no actions, suits or proceedings before
                           or against or  investigations of, the Depositor
                           pending, or to the knowledge of the  Depositor,
                           threatened, before any court, administrative
                           agency or other  tribunal, and no notice of any
                           such action, which, in the Depositor's
                           reasonable judgment, might materially and
                           adversely affect the  performance by the
                           Depositor of its obligations under this
                           Agreement, or the validity or enforceability of
                           this Agreement; and

                  (vii)    The Depositor is not in default with respect to any
                           order or decree of any court or any order, regulation
                           or demand of any federal, state, municipal or
                           governmental agency that would materially and
                           adversely affect its performance hereunder.

          Section 3.3 RESERVED.

          Section 3.4 PURCHASE AND SUBSTITUTION. (a) It is understood and agreed
that the representations and warranties set forth herein shall survive delivery
of the Certificates to the Certificateholders. With respect to any
representation or warranty contained in Sections 3.02 and 3.03 of the Sale and
Purchase Agreement that is made to the best of the Seller's knowledge, if it is
discovered by the Servicer, any Subservicer, the Depositor, the Trustee, the
Certificate Insurer or any Certificateholder that the substance of such
representation and warranty was inaccurate as of the Closing Date (or in the
case of the Subsequent Mortgage Loans, as of the respective Subsequent Transfer
Date) and such inaccuracy materially and adversely affects the value of the
related Mortgage Loan or the interest of the Certificate Insurer, then
notwithstanding the Seller's lack of knowledge with respect to the inaccuracy at
the time the representation or warranty was made, such inaccuracy shall be
deemed a breach of the applicable representation or warranty. Upon discovery by
the Seller, the Depositor, the Servicer, any Subservicer, the Trustee the
Certificate Insurer or any Certificateholder of a breach of any representations
and warranties which materially and adversely affects the value of the Mortgage
Loans or the interest of the Certificateholders, or which materially and
adversely affects the interests of the Certificate Insurer or the
Certificateholders in the related Mortgage Loan in the case of a representation
and warranty relating to a particular Mortgage Loan (notwithstanding that such
representation and warranty was made to the Seller's best knowledge), the party
discovering such breach shall give prompt written notice to the others. Subject
to the last paragraph of this Section 3.4, within 60 days of the earlier of its
discovery or its receipt of notice of any breach of a representation or
warranty, the Seller shall be required to (i) promptly cure such breach in all
material respects, (ii) purchase such Mortgage Loan on the next succeeding
Servicer Remittance Distribution Date, in the manner and at the related Loan
Repurchase Price, or (iii) remove such Mortgage Loan from the Trust Fund (in
which case the Mortgage Loan shall become a Deleted Mortgage Loan) and
substitute one or more Qualified Substitute Mortgage Loans; provided however,
that with respect to any Mortgage Loan for which the representation in Section
3.03(ac) of the Sale and Purchase Agreement is breached solely as a result of
flood conditions in the states of Indiana, Kentucky and Ohio during the period
from December 1996 through March 1997, the Seller shall use its best efforts to
substitute a Qualified Substitute Mortgage Loan for each such Mortgage Loan;
PROVIDED, that, such substitution is effected not later than the date which is
two years after the Startup Day or at such later date, if the Trustee and the
Certificate Insurer receive an Opinion of Counsel to the effect that such
substitution will not constitute a prohibited transaction for the purposes of
the REMIC provisions of the Code or cause the Upper Tier REMIC or Lower Tier
REMIC to fail to qualify as a REMIC at any time any Certificates are
outstanding. Any such substitution shall be accompanied by payment by the Seller
of the Substitution Adjustment, if any, to the Servicer to be deposited in the
Collection Account.

          (b) As to any Deleted Mortgage Loan for which the Seller substitutes a
Qualified Substitute Mortgage Loan or Loans, the Seller shall be required to
effect such substitution by delivering to the Trustee a certification in the
form attached hereto as Exhibit G, executed by a Servicing Officer and the
documents described in Sections 2.3(a)(i)-(vi) for such Qualified Substitute
Mortgage Loan or Loans.

          (c) The Servicer shall deposit in the Collection Account all principal
payments received and interest due in connection with such Qualified Substitute
Mortgage Loan or Loans after the date of such substitution or related cut-off
date, as applicable, set forth in the certification delivered to the Trustee.
Monthly Payments received with respect to Qualified Substitute Mortgage Loans on
or before the date of substitution or cut-off date, as applicable, will be
retained by the Seller. The Trust Fund will own all principal payments received
and interest due on the Deleted Mortgage Loan on or before the date of
substitution or cut-off date, as applicable, and the Seller shall thereafter be
entitled to retain all amounts subsequently received in respect of such Deleted
Mortgage Loan after the date of substitution or the related cut-off date, as
applicable. The Servicer shall give written notice to the Trustee and the
Certificate Insurer that such substitution has taken place and 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. Upon such substitution, such Qualified Substitute Mortgage Loan
or Loans shall be subject to the terms of this Agreement in all respects. For
purposes of this paragraph, "cut-off date" shall mean a date not later than the
related date of substitution.

          (d) It is understood and agreed that the obligations of the Seller to
cure, purchase or substitute for a defective Mortgage Loan constitute the sole
remedies of the Trustee, the Certificate Insurer and the Certificateholders with
respect to a breach of the representations and warranties of the Seller set
forth in Sections 3.02 and 3.03 of the Sale and Purchase Agreement (other than
the representation and warranty set forth in Section 3.03(g) to the extent of
any fines, penalties, costs or other damages or losses except the lost economic
value of the Mortgage Loan, the value of which the remedies provided for in
Section 2.06 and this Section 3.4 shall be deemed adequate for). The Trustee
shall give prompt written notice to the Certificate Insurer and each of the
Rating Agencies of any repurchase or substitution made pursuant to this Section
3.4 or Section 2.4(b) hereof.

          (e) Upon discovery by the Seller, the Servicer, the Trustee, the
Certificate Insurer or any Certificateholder that any Mortgage Loan does not
constitute a Qualified Mortgage, the party discovering such fact shall promptly
(and in any event within 5 days of the discovery) give written notice thereof to
the other parties and the Certificate Insurer. In connection therewith, the
Seller shall be required to repurchase or substitute a Qualified Substitute
Mortgage Loan for the affected Mortgage Loan within 60 days of the earlier of
such discovery by any of the foregoing parties, or the Trustee's or the Seller's
receipt of notice, in the same manner as it would a Mortgage Loan for a breach
of representation or warranty contained in Section 3.02 or 3.03 of the Sale and
Purchase Agreement. The Trustee shall reconvey to the Seller the Mortgage Loan
to be released pursuant hereto in the same manner, and on the same terms and
conditions, as it would a Mortgage Loan repurchased for breach of a
representation or warranty contained in Section 3.02 or 3.03 of the Sale and
Purchase Agreement.

          Section 3.5 INDEMNIFICATION OF THE TRUST FUND BY THE INDEMNITORS. The
Indemnitors hereby agree to indemnify the Trust Fund for any losses incurred by
it on any Liquidated Loan which had a Combined Loan-to-Value Ratio at
origination of greater than 100%; PROVIDED THAT such indemnity is limited to the
dollar amount of the difference at origination between the aggregate principal
balance of such Liquidated Loan and its Appraised Value; PROVIDED FURTHER, that
such indemnity is a nonrecourse obligation of each Indemnitor limited to an
amount equal to the aggregate of amounts received by such Indemnitor pursuant to
Section 6.5(vi) through (ix) and the outstanding principal amount of any demand
notes contributed by the Seller to either Indemnitor, if any. Upon receipt of
such funds from the Indemnitors, the Trustee shall deposit such amount in the
Certificate Account for distribution to Certificateholders. "Indemnitors" means,
together, Preferred Mortgage SPC Funding Corp. II and Preferred Mortgage SPC
Funding Corp.

          The Trustee, the Certificate Insurer and each Certificateholder, by
its acceptance of a Certificate agree (i) that they will not at any time
institute against any Indemnitor or join in any institution against any
Indemnitor of any bankruptcy, reorganization, arrangement, insolvency or
liquidation proceedings, or other proceedings under any United States Federal or
state bankruptcy or similar law, and (ii) the foregoing obligations of each
Indemnitor shall not constitute claims against such Indemnitor to the extent not
paid from amounts received by such Indemnitor or distributor on the Residual
Certificates, the Class B Certificates or any demand note contributed to such
Indemnitor.

          Section 3.6 THIRD PARTY CLAIMS. The Trustee shall reimburse the Seller
from amounts otherwise distributable on the Residual Certificates for all
amounts advanced by the Seller pursuant to the second sentence of Section
4.04(a)(ii) of the Sale and Purchase Agreement except when the relevant claim
relates directly to the failure of the Seller to perform its duties in
compliance with the terms of the Sale and Purchase Agreement.

          Section 3.7 INDEMNIFICATION OF CERTIFICATE ISSUER. By acceptance of
its Certificate, the Class RL Certificateholders agree to indemnify the
Certificate Insurer pursuant to Section 3.03 (f) of the Certificate Insurance
Agreement.

                                   ARTICLE IV

                                THE CERTIFICATES

          Section 4.1 THE CERTIFICATES. The Certificates shall be substantially
in the forms annexed hereto as Exhibit B-l-l, Exhibit B-1-2, Exhibit B-1-3,
Exhibit B-1-4, Exhibit B-1-5, Exhibit B-1-6, Exhibit B-2, Exhibit B-3, Exhibit
B-4 and Exhibit B-5. All Certificates shall be executed by manual or facsimile
signature on behalf of the Trustee by an authorized officer and authenticated by
the manual or facsimile signature of an authorized officer. Any Certificates
bearing the signatures of individuals who were at the time of the execution
thereof the authorized officers of the Trustee shall bind the Trustee,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the delivery of such Certificates or did not hold such offices
at the date of such Certificates. All Certificates issued hereunder shall be
dated the date of their authentication.

          Section 4.2 REGISTRATION OF TRANSFER AND EXCHANGE OF CERTIFICATES. (a)
The Trustee, as registrar, shall cause to be kept a register (the "Certificate
Register") in which, subject to such reasonable regulations as it may prescribe,
the Trustee shall provide for the registration of Certificates and the
registration of transfer of Certificates. The Trustee is hereby appointed
registrar for the purpose of registering and transferring Certificates, as
herein provided. The Certificate Insurer and the Servicer shall be entitled to
inspect and copy the Certificate Register and the records of the Trustee
relating to the Certificates during normal business hours upon reasonable
notice.

          (b) All Certificates issued upon any registration of transfer or
exchange of Certificates shall be valid evidence of the same ownership interests
in the Trust Fund and entitled to the same benefits under this Agreement as the
Certificates surrendered upon such registration of transfer or exchange.

          (c) Every Certificate presented or surrendered for registration of
transfer or exchange shall be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Trustee duly executed by the
Holder or holder thereof or his attorney duly authorized in writing. Every Class
A Certificate issued in definitive form shall include a statement of insurance,
attached hereto as Exhibit A-2 provided by the Certificate Insurer.

          (d) (i) No service charge shall be made to a Holder or holder for any
registration of transfer or exchange of Certificates, but the Trustee may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any registration of transfer or
exchange of Certificates.

          (ii) It is intended that the Class A Certificates be registered so as
to participate in a global book-entry system with the Depository, as set forth
herein. The Class A Certificates shall, except as otherwise provided in the next
paragraph, be initially issued in the form of six fully registered Class A
Certificates with a denomination equal to the related Original Class A Principal
Balance. Upon initial issuance, the ownership of each such Class A Certificate
shall be registered in the Certificate Register in the name of Cede & Co., or
any successor thereto, as nominee for the Depository. The Depositor and the
Trustee are hereby authorized to execute and deliver the Representation Letter
with the Depository. With respect to Class A Certificates registered in the
Certificate Register in the name of Cede & Co., as nominee of the Depository,
the Depositor, the Seller, the Servicer, the Trustee and the Certificate Insurer
shall have no responsibility or obligation to Direct or Indirect Participants or
beneficial owners for which the Depository holds Class A Certificates from time
to time as a Depository. Without limiting the immediately preceding sentence,
the Depositor, the Seller, the Servicer, the Trustee and the Certificate Insurer
shall have no responsibility or obligation with respect to (i) the accuracy of
the records of the Depository, Cede & Co., or any Direct or Indirect Participant
with respect to any Ownership Interest, (ii) the delivery to any Direct or
Indirect Participant or any other Person, other than a Certificateholder, of any
notice with respect to the Class A Certificates or (iii) the payment to any
Direct or Indirect Participant or any other Person, other than a
Certificateholder, of any amount with respect to any distribution of principal
or interest on the Class A Certificates. No Person other than a
Certificateholder shall receive a certificate evidencing such Class A
Certificate. Upon delivery by the Depository to the Trustee of written notice to
the effect that the Depository has determined to substitute a new nominee in
place of Cede & Co., and subject to the provisions hereof with respect to the
payment of interest by the mailing of checks or drafts to the Certificateholders
appearing as Certificateholders at the close of business on a Record Date, the
name "Cede & Co." in this Agreement shall refer to such new nominee of the
Depository.

          In the event that (x) the Depository or the Seller advises the Trustee
and the Certificate Insurer in writing that the Depository is no longer willing
or able to discharge properly its responsibilities as nominee and depository
with respect to the Class A Certificates and the Seller or the Depository is
unable to locate a qualified successor or (ii) the Trustee at its sole option
elects to terminate the book-entry system through the Depository, the Class A
Certificates shall no longer be restricted to being registered in the
Certificate Register in the name of Cede & co. (or a successor nominee) as
nominee of the Depository. At that time, the Seller may determine that the Class
A Certificates shall be registered in the name of and deposited with a successor
depository operating a global book-entry as may be acceptable to the Seller, or
such depository's agent or designee but, if the Seller does not select such
alternative global book-entry system, then the Class A Certificates may be
registered in whatever name or names Certificateholders transferring Class A
Certificates shall designate, in accordance with the provisions hereof.

          Notwithstanding any other provision of this Agreement to the contrary,
so long as any Class A Certificate is registered in the name of Cede & Co., as
nominee of the Depository, all distributions of principal or interest on such
Class A Certificates as the case may be and all notices with respect to such
Class A Certificates as the case may be shall be made and given, respectively,
in the manner provided in the Representation Letter.

          (e) Except as provided in Section 4.2(e)(ii), no transfer, sale,
pledge or other disposition of any Class B or Residual Certificate shall be made
unless such transfer, sale, pledge or other disposition is exempt from the
registration requirements of the Securities Act of 1933, as amended (the "Act"),
and any applicable state securities laws or is made in accordance with said Act
and laws. In the event that a transfer of a Class B or Residual Certificate is
to made under this Section 4.2(e)(i), (a) the Trustee shall require an Opinion
of Counsel acceptable to and in form and substance satisfactory to the Trustee
and the Depositor that such transfer shall be made pursuant to an exemption,
describing the application exemption and the basis therefor, from said Act and
laws or is being made pursuant to said Act and laws, which Opinion of Counsel
shall not be an expense of the Trustee, the Depositor or the Servicer, PROVIDED
THAT such Opinion of Counsel will not be required in connection with the initial
transfer of any such Certificate by the Depositor or any affiliate thereof, to a
non-affiliate of the Depositor and (b) the Trustee shall require the transferee
to execute a representation letter, substantially in the form of Exhibit H
hereto, and Trustee shall require the transferor to execute a representation
letter, substantially in the form of Exhibit I hereto, each acceptable to and in
form and substance satisfactory to the Depositor and the Trustee certifying to
the Depositor and the Trustee the facts surrounding such transfer, which
representation letters shall not be an expense of the Trustee, the Depositor or
the Servicer, PROVIDED THAT such representation letter will not be required in
connection with any transfer of any such Certificate by the Depositor to an
affiliate of the Depositor. Any such Certificateholder desiring to effect such
transfer shall, and does hereby agree to, indemnify the Trustee, the Depositor,
the Servicer and the Certificate Insurer against any liability that may result
if the transfer is not so exempt or is not made in accordance with such
applicable federal and state laws.

          (ii) Transfers of Certificates may be made in accordance with Section
4.2(e)(ii) if the prospective transferee of a Certificate provides the Trustee
and the Depositor with an investment letter substantially in the form of Exhibit
J attached hereto, which investment letter shall not be an expense of the
Trustee, the Depositor or the Servicer, and which investment letter states that,
among other things, such transferee is a "qualified institutional buyer" as
defined under Rule 144A. Such transfers shall be deemed to have complied with
the requirements of Section 4.2(e)(i) hereof; PROVIDED, HOWEVER, that no
Transfer of any of the Certificates may be made pursuant to this Section
4.2(e)(ii) by the Depositor. Any such Certificateholder desiring to effect such
transfer shall, and does hereby agree to indemnify the Trustee, the Depositor,
the Servicer and the Certificate Insurer against any liability that may result
if the transfer is not so exempt or is not made in accordance with such
applicable federal and state laws.

          (f) Each Person who has or who acquires any Ownership Interest in a
Residual Certificate shall be deemed by the acceptance or acquisition of such
Ownership Interest to have agreed to be bound by the following provisions and to
have irrevocably appointed the Trustee or its designee as its attorney-in-fact
to negotiate the terms of any mandatory sale under subclause (vii) below and to
execute all instruments of transfer and to do all other things necessary in
connection with any such sale, and the rights of each Person acquiring any
Ownership Interest in a Residual Certificate are expressly subject to the
following provisions:

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

                                    (ii) In connection with any proposed
                  Transfer of any Ownership Interest in a Residual Certificate,
                  the Trustee shall require delivery to it, and shall not
                  register the Transfer of any Residual Certificate until its
                  receipt of, an affidavit and agreement (a "Transfer Affidavit
                  and Agreement") attached hereto as Exhibit K from the proposed
                  Transferee, representing and warranting, among other things,
                  that such Transferee is a Permitted Transferee, that it is not
                  acquiring its Ownership Interest in the Residual Certificate
                  that is the subject of the proposed Transfer as a nominee,
                  trustee or agent for any Person that is not a Permitted
                  Transferee, that for so long as it retains its Ownership
                  Interest in a Residual Certificate, it will endeavor to remain
                  a Permitted Transferee, and that it has reviewed the
                  provisions of this Section 4.2(f) and agrees to be bound by
                  them.

                                    (iii) Notwithstanding the delivery of a
                  Transfer Affidavit and Agreement by a proposed Transferee
                  under clause (ii) above, if a Responsible Officer of the
                  Trustee has actual knowledge that the proposed Transferee is
                  not a Permitted Transferee, no Transfer of an Ownership
                  Interest in a Residual Certificate to such proposed Transferee
                  shall be effected.

                                    (iv) Each Person holding or acquiring any
                  Ownership Interest in a Residual Certificate shall agree (x)
                  to require a Transfer Affidavit and Agreement from any other
                  Person to whom such Person attempts to transfer its Ownership
                  Interest in a Residual Certificate and (y) not to transfer its
                  Ownership Interest unless it provides a certificate (attached
                  hereto as Exhibit L) to the Trustee stating that, among other
                  things, it has no actual knowledge that such other Person is
                  not a Permitted Transferee.

                                    (v) Each Person holding or acquiring an
                  Ownership Interest in a Residual Certificate, by purchasing an
                  Ownership Interest in such Certificate, agrees to give the
                  Trustee written notice that it is a "pass-through interest
                  holder" within the meaning of temporary Treasury Regulation
                  Section 1.67-3T(a)(2)(i)(A) immediately upon acquiring an
                  Ownership Interest in a Residual Certificate, if it is, or is
                  holding an Ownership Interest in a Residual Certificate on
                  behalf of, a "pass-through interest holder."

                                    (vi) The Trustee will register the Transfer
                  of any Residual Certificate only if it shall have received the
                  Transfer Affidavit and Agreement. In addition, no Transfer of
                  a Residual Certificate shall be made unless the Trustee shall
                  have received a representation letter from the Transferee of
                  such Certificate to the effect that such Transferee is a
                  Permitted Transferee and is not a "disqualified organization"
                  (as defined in Section 860E(e)(5) of the Code).

                                    (vii) Any attempted or purported transfer of
                  any Ownership Interest in a Residual Certificate in violation
                  of the provisions of this Section 4.2 shall be absolutely null
                  and void and shall vest no rights in the purported transferee.
                  If any purported transferee shall become a Holder of a
                  Residual Certificate in violation of the provisions of this
                  Section 4.2, then the last preceding Permitted Transferee
                  shall be restored to all rights as Holder thereof retroactive
                  to the date of registration of transfer of such Residual
                  Certificate. The Trustee shall notify the Servicer upon
                  receipt of written notice or discovery by a Responsible
                  Officer that the registration of transfer of a Residual
                  Certificate was not in fact permitted by this Section 4.2.
                  Knowledge shall not be imputed to the Trustee with respect to
                  an impermissible transfer in the absence of such a written
                  notice or discovery by a Responsible Officer. The Trustee
                  shall be under no liability to any Person for any registration
                  of transfer of a Residual Certificate that is in fact not
                  permitted by this Section 4.2 or for making any payments due
                  on such 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 transfer was registered after
                  receipt of the related Transfer Affidavit and Transfer
                  Certificate. The Trustee shall be entitled, but not obligated
                  to recover from any Holder of a Residual Certificate that was
                  in fact not a Permitted Transferee at the time it became a
                  Holder or, at such subsequent time as it became other than a
                  Permitted Transferee, all payments made on such Residual
                  Certificate at and after either such time. Any such payments
                  so recovered by the Trustee shall be paid and
                  delivered by the Trustee to the last preceding Holder
                  of such Certificate.

                                    (viii) If any purported transferee shall
                  become a Holder of a Residual Certificate in violation of the
                  restrictions in this Section 4.2, then the Trustee or its
                  designee shall have the right, without notice to the Holder or
                  any prior Holder of such Residual Certificate, to sell such
                  Residual Certificate to a purchaser selected by the Trustee or
                  its designee on such reasonable terms as the Trustee or its
                  designee may choose. Such purchaser may be the Trustee itself
                  or any Affiliate of the Trustee. The proceeds of such sale,
                  net of commissions, expenses and taxes due, if any, will be
                  remitted by the Trustee to the last preceding purported
                  transferee of such Residual Certificate, except that in the
                  event that the Trustee determines that the Holder or any prior
                  Holder of such Residual Certificate may be liable for any
                  amount due under this Section 4.2 or any other provision 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 subclause (viii)
                  shall be determined in the sole discretion of the Trustee or
                  its designee, and it shall not be liable to any Person having
                  an Ownership Interest in a Residual Certificate as a result of
                  its exercise of such discretion.

          (g) The Trustee shall make available to the Internal Revenue Service
and those Persons specified by the REMIC Provisions, all information necessary
to compute any tax imposed (A) as a result of the transfer of an ownership
interest in a Residual Certificate to any Person who is a Disqualified
Organization, including the information regarding "excess inclusions" of such
Residual Certificates required to be provided to the Internal Revenue Service
and certain Persons as described in Treasury Regulations Sections 1.860D-l(b)(5)
and 1.860E-2(a)(5), and (B) as a result of any regulated investment company,
real estate investment trust, common trust fund, partnership, trust, estate or
organization described in Section 1381 of the Code holds an Ownership Interest
in a Residual Certificate having as among its record holders at any time any
Person who is a Disqualified Organization. The Trustee may charge and shall be
entitled to reasonable compensation for providing such information as may be
required from those Persons which may have had a tax imposed upon them as
specified in clauses (A) and (B) of this paragraph for providing such
information.

          (h) The provisions of Section 4.2 may be modified, added to or
eliminated, PROVIDED THAT there shall have been delivered to the Trustee and the
Certificate Insurer an Opinion of Counsel to the effect that such modification
of, addition to or elimination of such provisions will not cause the Upper-Tier
REMIC or Lower-Tier REMIC to cease to qualify as a REMIC and will not cause (x)
the Upper-Tier REMIC or Lower-Tier REMIC to be subject to an entity-level tax
caused by the Transfer of any Ownership Interest in a Residual Certificate to a
Person that is not a Permitted Transferee or (y) a Person other than the
prospective transferee to be subject to a REMIC-related tax caused by the
Transfer of an Ownership Interest in a Residual Certificate to a Person that is
not a Permitted Transferee.

          (i) No transfer of a Class B Certificate or a Residual Certificate or
any interest therein shall be made to any (a) employee benefit plans (as defined
in Section 3(3) of ERISA) subject to the provisions of Title I of ERISA, (b)
plans described in section 4975(e)(1) of the Code, including individual
retirement accounts or Keogh plans, (c) any entities whose underlying assets
include assets of a plan described in (a) or (b) above by reason of such a
plan's investment in such entities (each a "Plan"). Prior to the earlier of (i)
the date on which the Pre- Funding Period expires and (ii) the date on which the
U.S. Department of Labor amends Prohibited Transaction Class Exemption 90-32 to
permit the use thereunder of pre-funding accounts as described herein, no
transfer of a Class A Certificate shall be made to any Plan. The Trustee and the
Servicer shall require the prospective transferee of any Class B Certificate or
Residual Certificate to certify (in the form of Exhibit M-1 hereto) that it is
not a Plan. The Trustee and the Servicer shall require the prospective
transferee of any Class A Certificate (1) if such proposed transfer shall occur
during the period the proposed transfer of the Class A Certificates is not
permitted to be made to Plans (as described above), to certify (in the form of
Exhibit M-1 hereto) that it is not a Plan or (2) if such proposed transfer shall
occur after such period, to execute a certificate in the form of Exhibit M-2
hereto.

          (j) Subject to the restrictions set forth in this Agreement, upon
surrender for registration of transfer of any Certificate at the office or
agency of the Trustee located in New York, New York, the Trustee shall execute,
authenticate and deliver in the name of the designated transferee or
transferees, a new Certificate of the same Class and evidencing the same
Percentage Interest, and in any other case, the equivalent undivided beneficial
ownership interest in the Trust Fund and dated the date of authentication by the
Trustee. At the option of the Certificateholders, Certificates may be exchanged
for other Certificates of Authorized Denominations of a like aggregate undivided
beneficial ownership interest, upon surrender of the Certificates to be
exchanged at such office. Whenever any Certificates are so surrendered for
exchange, the Trustee shall execute, authenticate and deliver the Certificates
which the Certificateholder making the exchange is entitled to receive. No
service charge shall be made for any transfer or exchange of Certificates, but
the Trustee may require payment of a sum sufficient to cover any tax or
governmental charge that may be imposed in connection with any transfer or
exchange of Certificates. All Certificates surrendered for transfer and exchange
shall be canceled by the Trustee.

          Section 4.3 MUTILATED, DESTROYED; LOST OR STOLEN CERTIFICATES. If (a)
any mutilated Certificate is surrendered to the Trustee, or the Trustee receives
evidence to its satisfaction of the destruction, loss or theft of any
Certificate, and (b) there is delivered to the Certificate Insurer and the
Trustee such security or indemnity as may reasonably be required by each of them
to save each of them harmless, then, in the absence of notice to the Certificate
Insurer and the Trustee that such Certificate has been acquired by a bona fide
purchaser, the Trustee shall execute, 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 representing an equivalent beneficial ownership
interest, but bearing a number not contemporaneously outstanding. Upon the
issuance of any new Certificate under this Section 4.3, the Trustee may require
the payment by the transferee Certificateholder of a sum sufficient to cover any
tax or other governmental charge that may be imposed in relation thereto and
their fees and expenses connected therewith. Any duplicate Certificate issued
pursuant to this Section 4.3 shall constitute complete and indefeasible evidence
of ownership in the Trust Fund, as if originally issued, whether or not the
mutilated, destroyed, lost or stolen Certificate shall be found at any time.

          Section 4.4 PERSONS DEEMED OWNERS. Prior to due presentation of a
Certificate for registration of transfer and subject to the provisions of
Section 4.2 and Article XI, the Servicer, the Depositor, the Seller, the
Certificate Insurer and the Trustee may treat the Person in whose name any
Certificate is registered as the owner of such Certificate for the purpose of
receiving remittances pursuant to Section 6.5 and for all other purposes
whatsoever, and the Servicer, the Depositor, the Seller, the Certificate Insurer
and the Trustee shall not be affected by notice to the contrary.

               ADMINISTRATION AND SERVICING OF THE MORTGAGE LOANS

          Section 5.1 APPOINTMENT OF THE SERVICER. (a) Advanta Mortgage Corp.
USA agrees to act as the Servicer and to perform all servicing duties under this
Agreement subject to the terms hereof.

          (b) The Servicer shall service and administer the Mortgage Loans on
behalf of the Trustee and the Certificate Insurer and shall have full power and
authority, acting alone or through one or more Subservicers, to do 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
Servicer, in its own name or the name of a Subservicer, may, and is hereby
authorized and empowered by the Trustee to, execute and deliver, on behalf of
itself, the Certificateholders and the Trustee or any of them, 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, the insurance policies and accounts related thereto and the properties
subject to the Mortgages. Upon the execution and delivery of this Agreement, and
from time to time as may be required thereafter, the Trustee shall furnish the
Servicer or its Subservicers with any powers of attorney and such other
documents as may be necessary or appropriate to enable the Servicer to carry out
its servicing and administrative duties hereunder.

          In servicing and administering the Mortgage Loans, the Servicer shall
employ procedures consistent with Accepted Servicing Practices and in a manner
consistent with recovery under any insurance policy required to be maintained by
the Servicer pursuant to this Agreement. The Servicer shall notify the
Certificate Insurer and the Seller of any material changes to its Accepted
Servicing Practices.

          In servicing and administering the Mortgage Loans, the Servicer may,
in its sole discretion, and is hereby authorized to obtain and use consumer
reports, including but not limited to Credit Bureau Risk Scores, on behalf of
the Trust Fund for any lawful purpose, including but not limited to account
review and collection activities.

          Costs incurred by the Servicer in effectuating the timely payment of
taxes and assessments on the property securing a Mortgage Note and foreclosure
costs may be added by the Servicer to the amount owing under such Mortgage Note
where the terms of such Mortgage Note so permit; PROVIDED, HOWEVER, that the
addition of any such cost shall not be taken into account for purposes of
calculating the principal amount of the Mortgage Note and the Mortgage Loan
secured by the Mortgage Note or distributions to be made to Certificateholders.
Such costs shall be recoverable by the Servicer pursuant to Section 5.9.
Notwithstanding any other provision of this Agreement, the Servicer shall at all
times service the Mortgage Loans in a manner consistent with the provisions of
this Section 5.1(b).

          (c) Subject to Section 5. 11, the Servicer is hereby authorized and
empowered to execute and deliver on behalf of the Trustee and each
Certificateholder, all instruments of satisfaction or cancellation, or of
partial or full release, discharge and all other comparable instruments, with
respect to the Mortgage Loans and with respect to the Mortgaged Properties. If
reasonably required by the Servicer, the Trustee shall execute any powers of
attorney furnished to the Trustee by the Servicer and other documents necessary
or appropriate to enable the Servicer to carry out its servicing and
administrative duties under this Agreement.

          (d) On and after such time as the Trustee receives the resignation of,
or notice of the removal of, the Servicer from its rights and obligations under
this Agreement, and with respect to resignation pursuant to Section 5.23, after
receipt by the Trustee and the Certificate Insurer of the Opinion of Counsel
required pursuant to Section 5.23, the Trustee or its designee approved by the
Certificate Insurer or other successor servicer approved by the Certificate
Insurer shall assume all of the rights and obligations of the Servicer, subject
to Section 7.2 hereof. The Servicer shall, upon request of the Trustee but at
the expense of the Servicer, deliver to the Trustee all documents and records
relating to the Mortgage Loans and an accounting of amounts collected and held
by the Servicer and otherwise use its best efforts to effect the orderly and
efficient transfer of servicing rights and obligations to the assuming party.

          (e) The Servicer shall deliver a list of Servicing Officers to the
Trustee and the Certificate Insurer by the Closing Date, which list may, from
time to time, be amended, modified or supplemented by the subsequent delivery to
the Trustee and the Certificate Insurer of any superseding list of Servicing
Officers.

          Section 5.2 SUBSERVICING AGREEMENTS BETWEEN THE SERVICER AND
SUBSERVICERS. (a) The Servicer may, subject to the prior written approval of the
Certificate Insurer, enter into Subservicing Agreements with Subservicers for
the performance of servicing and administration of the Mortgage Loans. Each
Subservicer shall be either (i) a depository institution the accounts of which
are insured by the FDIC or (ii) another entity that engages in the business of
originating, acquiring or servicing mortgage loans, and in either case shall be
authorized to transact business in the state or states where the related
Mortgaged Properties it is to service are situated. In addition, each
Subservicer will obtain and preserve its qualifications to do business as a
foreign corporation in each jurisdiction in which such qualification is or shall
be necessary to protect the validity and enforceability of this Agreement, the
Certificates and any of the Mortgage Loans and to perform or cause to be
performed its duties under the related Subservicing Agreement which shall
provide that the Subservicer's rights shall automatically terminate upon the
termination, resignation or other removal of the Servicer under this Agreement.
Each account used by any Subservicer for the deposit of payments on any of the
Mortgage Loans shall be an Eligible Account.

          (b) Notwithstanding any Subservicing Agreement or arrangement with a
collection agency, any of the provisions of this Agreement relating to
agreements or arrangements between the Servicer and a Subservicer or any
collection agency or reference to actions taken through a Subservicer, a
collection agency or otherwise, the Servicer shall remain obligated and
primarily liable to the Trustee, the Certificate Insurer and the
Certificateholders for the servicing and administering of the Mortgage Loans in
accordance with the provisions of this Agreement without diminution of such
obligation or liability by virtue of such Subservicing Agreements or
arrangements with a Subservicer or any collection agency or by virtue of
indemnification from the Subservicer or any collection agency and to the same
extent and under the same terms and conditions as if the Servicer alone were
servicing and administering the Mortgage Loans. For purposes of this Agreement,
the Servicer shall be deemed to have received payments on Mortgage Loans when
the Subservicer or any collection agency, as the case may be, has received such
payments.

          In the event the Servicer shall for any reason no longer be the
Servicer (including by reason of an Event of Default), the Trustee or its
designee may, with the prior written consent of the Certificate Insurer, or
shall, at the direction of the Certificate Insurer, either (i) assume all of the
rights and obligations of the Servicer under each Subservicing Agreement that
the Servicer may have entered into or (ii) notwithstanding anything to the
contrary contained in each such Subservicing Agreement, terminate the related
Subservicer without being required to pay any fee in connection therewith.

          Section 5.3 COLLECTION OF CERTAIN MORTGAGE LOAN PAYMENTS; COLLECTION
ACCOUNT. (a) The Servicer shall use its best 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 any
applicable primary mortgage insurance policy, follow such collection procedures
as shall constitute Accepted Servicing Practices. The Servicer may utilize the
services of any collection agencies in connection with its collection efforts.
The costs of any such collection agency shall be a "Servicing Advance."

          The Servicer shall establish and maintain in the name of the Trustee
the Collection Account (collectively, the "Collection Account"), in trust for
the benefit of the Holders of the Certificates and the Certificate Insurer. The
Servicer shall promptly provide notice to the Certificate Insurer, the Trustee
and each Rating Agency of any creation and establishment of a Collection Account
hereunder. The Collection Account shall be established and maintained as an
Eligible Account.

          The Servicer shall deposit in the Collection Account any amounts
representing Monthly Payments on the Mortgage Loans due or to be applied as of a
date after the Cut-Off Date, and thereafter, on a daily basis within two
Business Days of receipt (except as otherwise permitted herein), the following
payments and collections received or made by it (other than in respect of
principal of and interest on the Mortgage Loans due on or before the Cut-Off
Date):

                           (i) all payments received after the Cut-Off Date on
                  account of principal on the Mortgage Loans and all Principal
                  Prepayments, Curtailments and all Net REO Proceeds collected
                  after the Cut-Off Date;

                           (ii) all payments received after the Cut-Off Date on
                  account of interest on the Mortgage Loans (other than payments
                  of interest that accrued on each Mortgage Loan up to and
                  including the Due Date immediately preceding the Cut-Off
                  Date);

                           (iii) all Net Liquidation Proceeds;

                           (iv)  all Insurance Proceeds;

                           (v)   all Released Mortgaged Property Proceeds;

                           (vi)  any amounts payable in connection with the
                  repurchase of any Mortgage Loan and the amount of any
                  Substitution Adjustment pursuant to Sections 2.4 and
                  3.4 hereof;

                           (vii) any amount expressly required to be deposited
                  in the Collection Account in accordance with certain
                  provisions of this Agreement, including, without limitation
                  amounts in respect of the termination of the Trust Fund, and
                  amounts referenced in Sections 2.4(b), 3.4, 5.3, 5.6, and
                  6.6(d) of this Agreement; and

                           (viii) any deficiency judgments collected by
                  the Servicer;

PROVIDED, HOWEVER, that the Servicer shall be entitled, at its election to pay
to itself the applicable Servicing Fee. All other amounts shall be deposited in
the Collection Account not later than the second Business Day following the day
of receipt by the Servicer.

          The Servicer may direct, in writing, the institution maintaining the
Collection Account to invest the funds in the Collection Account, only in
Permitted Investments. No Permitted Investment shall be sold or disposed of at a
gain prior to maturity unless the Servicer has obtained an Opinion of Counsel
delivered to the Trustee and the Certificate Insurer (at the Servicer's expense)
that such sale or disposition will not cause either the Upper-Tier REMIC or
Lower-Tier REMIC to be subject to the tax on income from prohibited transactions
imposed by Code Section 860F(a)(1), otherwise subject either Upper-Tier REMIC or
Lower-Tier REMIC to tax or cause the Trust Fund to fail to qualify as a REMIC.
All income (other than any gain from a sale or disposition of the type referred
to in the preceding sentence) realized from any such Permitted Investment shall
be for the benefit of the Servicer as additional servicing compensation. The
amount of any losses incurred in respect of any such investments shall be
deposited in the Collection Account by the Servicer out of its own funds
immediately as realized.

          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 those described in the
last paragraph of Section 5.13 and payments in the nature of prepayment charges,
late payment charges or assumption fees need not be deposited by the Servicer in
the Collection Account. Notwithstanding any provision herein to the contrary, if
the Servicer deposits in the Collection Account any amount not required to be
deposited therein, it may at any time withdraw such amount from the Collection
Account. All funds deposited by the Servicer in the Collection Account shall be
held therein for the account of the Trustee in trust for the Certificateholders
and the Certificate Insurer until disbursed in accordance with Section 6.1 or
withdrawn in accordance with Section 5.4.

          (b) Prior to the time of their required deposit in the Collection
Account, all amounts required to be deposited therein may be deposited in an
account in the name of Servicer, PROVIDED THAT such account is an Eligible
Account. The Servicer hereby acknowledges all such related funds shall be held
in trust for the benefit of the Certificateholders and the Certificate Insurer
pursuant to the terms hereof.

          (c) The Collection Account may, upon written notice by the Trustee to
the Certificate Insurer, be transferred by the Servicer to a different
depository so long as such transfer is to an Eligible Account.

          Section 5.4 PERMITTED WITHDRAWALS FROM THE COLLECTION ACCOUNT. The
Servicer may, from time to time, make withdrawals from the Collection Account
for the following purposes, without duplication:

          (a) to pay to itself from any funds in the Collection Account any
accrued and unpaid Servicing Fees and unreimbursed Delinquency Interest Advances
and Servicing Advances, PROVIDED, HOWEVER, that Servicing Advances may only be
reimbursed from late collections on the related Mortgage Loan, Insurance
Proceeds and Liquidation Proceeds;

          (b) to reimburse itself for any Delinquency Interest Advances or
Servicing Advances determined in good faith to have become Nonrecoverable
Advances, such reimbursement to be made from any funds in the Collection
Account;

          (c) to withdraw from the Collection Account any Preference Amount
received from a Mortgagor;

          (d) to withdraw any funds deposited in the Collection Account that
were not required to be deposited therein;

          (e) to withdraw from the Collection Account any funds needed to pay
itself Servicing Compensation pursuant to Section 5.13 hereof to the extent not
retained or paid pursuant to Section 5.3, 5.4 or 5.13;

          (f) to withdraw from the Collection Account to pay to the Seller with
respect to each Mortgage Loan or property acquired in respect thereof that has
been repurchased or replaced pursuant to Section 2.4 or 3.4 or to pay to itself
with respect to each Mortgage Loan or property acquired in respect thereof that
has been purchased pursuant to Section 8.1, all amounts received thereon and not
required to be distributed as of the date on which the related repurchase or
purchase price or Principal Balance, as the case may be, was determined as a
result of such repurchase or replacement;

          (g) to withdraw from the Collection Account to pay to the Seller with
respect to each Mortgage Loan any interest accrued and unpaid on such Mortgage
Loan prior to the Cut-Off Date, to the extent received;

          (h) to transfer funds from the Collection Account necessary to make
deposits to the Certificate Account (which shall include the Trustee Fee) in the
amounts and in the manner provided for herein;

          (i) to pay itself any interest earned on or investment income earned
with respect to funds in the Collection Account;

          (j) to reimburse itself or the Depositor pursuant to 11. 1; and

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

          Section 5.5 PAYMENT OF TAXES, INSURANCE AND OTHER CHARGES. With
respect to each Mortgage Loan as to which the Servicer maintains escrow
accounts, the Servicer shall maintain accurate records reflecting the status of
ground rents, taxes, assessments, water rates and other charges which are or may
become a lien upon the Mortgaged Property and the status of primary mortgage
guaranty insurance premiums, if any, and casualty insurance coverage and shall
obtain, from time to time, all bills for the payment of such charges (including
renewal premiums) and shall effect payment thereof prior to the applicable
penalty or termination date and at a time appropriate for securing maximum
discounts allowable, employing for such purpose deposits of the Mortgagor in any
escrow account which shall have been estimated and accumulated by the Servicer
in amounts sufficient for such purposes, as allowed under the terms of the
Mortgage. To the extent that a Mortgage does not provide for escrow payments,
the Servicer shall, if it has received notice of a default or deficiency,
monitor such payments to determine if they are made by the Mortgagor.

          Section 5.6 MAINTENANCE OF CASUALTY INSURANCE. With respect to each
Mortgage Loan, the Servicer shall maintain accurate records reflecting casualty
insurance coverage. For each Mortgage Loan, the Servicer shall maintain or cause
to be maintained, to the extent required by the related Mortgage Loan to be
maintained by the Mortgagor, fire and casualty insurance with a standard
mortgagee clause and extended coverage in an amount which is not less than the
replacement value of the improvements securing such Mortgage Loan or the unpaid
principal balance of such Mortgage Loan, whichever is less. If, upon origination
of the Mortgage Loan, the Mortgaged Property was in an area identified in the
Federal Register by the Federal Emergency Management Agency as having special
flood hazards (and such flood insurance has been made available) the Servicer
will cause to be maintained, to the extent required by the related Mortgage Loan
to be maintained by the Mortgagor, a flood insurance policy meeting the
requirements of the current guidelines of the Federal Insurance Administration
with a generally acceptable insurance carrier, in an amount representing
coverage not less than the least of (i) the unpaid principal balance of the
Mortgage Loan, (ii) the full insurable value of the Mortgaged Property and (iii)
the maximum amount of insurance available under the Flood Disaster Protection
Act of 1973. With respect to each Mortgage Loan, the Servicer shall also
maintain fire insurance with extended coverage and, if applicable, flood
insurance on REO Property in an amount which is at least equal to the lesser of
(i) the maximum insurable value of the improvements which are a part of such
property and (ii) the principal balance owing on such Mortgage Loan at the time
of such foreclosure or grant of deed in lieu of foreclosure. It is understood
and agreed that such insurance shall be with insurers approved by the Servicer
and that no earthquake or other additional insurance is to be required of any
Mortgagor or to be maintained on property acquired in respect of a defaulted
loan, other than pursuant to such applicable laws and regulations as shall at
any time be in force and as shall require such additional insurance. Pursuant to
Section 5.3, any amounts collected by the Servicer under any insurance policies
maintained pursuant to this Section 5.6 (other than amounts to be applied to the
restoration or repair of the related Mortgaged Property or released to the
Mortgagor in accordance with Accepted Servicing Practices and applicable law)
shall be deposited into the Collection Account, subject to withdrawal pursuant
to Section 5.4. Any cost incurred by the Servicer in maintaining any such
insurance shall be added to the amount owing under the Mortgage Loan where the
terms of the Mortgage Loan so permit; PROVIDED, HOWEVER, that the addition of
any such cost shall not be taken into account for purposes of calculating the
principal amount of the Mortgage Note or the Mortgage Loan secured by the
Mortgage Note or the distributions to be made to the Certificateholders. Such
costs shall be recoverable by the Servicer pursuant to Section 5.4. In the event
that the Servicer shall obtain and maintain a blanket policy issued by an
insurer that is acceptable to FNMA or FHLMC, insuring against hazard losses on
all of the Mortgage Loans, it shall conclusively be deemed to have satisfied its
obligation as set forth in the second and third sentences of this Section 5.6,
it being understood and agreed that such policy may contain a deductible clause,
in which case the Servicer shall, in the event that there shall not have been
maintained on the related mortgaged or acquired property an insurance policy
complying with the second and third sentences of this Section 5.6 and there
shall have been a loss which would have been covered by such a policy had it
been maintained, be required to deposit from its own funds into the Collection
Account the amount not otherwise payable under the blanket policy because of
such deductible clause.

          Section 5.7 SERVICER ACCOUNT. In addition to the Collection Account,
the Servicer shall be permitted to establish and maintain one or more Servicer
Accounts (collectively, the "Servicer Account"), which shall be an Eligible
Account, in which the Servicer may deposit all payments by, and collections
from, the Mortgagors received in connection with the Mortgage Loans prior to the
Servicer's deposit of all such funds required to be deposited into the
Collection Account. Withdrawals may be made out of such collections in the
Servicer Account to reimburse the Servicer for any required advances not
otherwise made from amounts on deposit in the Collection Account or for any
refunds made by the Servicer of any sums determined to be overages, or to pay
any interest owed to Mortgagors on such account to the extent required by law,
and in order to terminate and clear the Servicer Account upon the termination of
this Agreement upon the termination of the Trust Fund.

          Section 5.8 FIDELITY BOND: ERRORS AND OMISSIONS POLICY. (a) The
Servicer shall maintain with a responsible company, and at its own expense, a
blanket fidelity bond (a "Fidelity Bond") and an errors and omissions insurance
policy (an "Errors and Omissions Policy"), in a minimum amount acceptable to
FNMA or otherwise in an amount as is commercially available at a cost that is
not generally regarded as excessive by industry standards, with broad coverage
on all officers, employees or other persons acting in any capacity requiring
such persons to handle funds, money, documents or papers relating to the
Mortgage Loans ("Servicer Employees"). Any such fidelity bond and errors and
omissions insurance shall protect and insure the Servicer against losses,
including losses resulting from forgery, theft, embezzlement, fraud, errors and
omissions and negligent acts of such Servicer Employees. Such fidelity bond
shall also protect and insure the Servicer against losses in connection with the
release or satisfaction of a Mortgage Loan without having obtained payment in
full of the indebtedness secured thereby. No provision of this Section 5.8
requiring such fidelity bond and errors and omissions insurance shall diminish
or relieve the Servicer from its duties and obligations as set forth in this
Agreement.

          (b) The Servicer shall be deemed to have complied with this provision
if one of its respective Affiliates has such a Fidelity Bond and Errors and
Omissions Policy and, by the terms of such fidelity bond and errors and omission
policy, the coverage afforded thereunder extends to the Servicer and the
Servicer Employees. The Servicer shall cause each and every Subservicer for it
to maintain a policy of insurance covering errors and omissions and a fidelity
bond which would meet the requirements of Section 5.8(a) hereof.

          Section 5.9 COLLECTION OF TAXES, ASSESSMENTS AND OTHER ITEMS. The
Servicer shall deposit all payments by Mortgagors for taxes, assessments,
primary mortgage or hazard insurance premiums or comparable items in the
Servicer Account. Withdrawals from the Servicer Account may be made to effect
payment of taxes, assessments, primary mortgage or hazard insurance premiums or
comparable items, to reimburse the Servicer out of related collections for any
advances made in the nature of any of the foregoing, to refund to any Mortgagors
any sums determined to be overages, or to pay any interest owed to Mortgagors on
such account to the extent required by law or to clear and terminate the
Servicer Account at the termination of this Agreement upon the termination of
the Trust Fund. The Servicer shall advance the payments referred to in the first
sentence of this Section 5.9 that are not timely paid by the Mortgagors on the
date when the tax, assessment, premium or other cost for which such payment is
intended is due, but the Servicer shall be required to so advance only to the
extent that such advances, in the good faith judgment of the Servicer, will be
recoverable by the Servicer pursuant to Section 5.4 out of Liquidation Proceeds,
Insurance Proceeds or otherwise.

          Section 5.10 ENFORCEMENT OF DUE-ON-SALE CLAUSES; ASSUMPTION
AGREEMENTS. In any case in which a Mortgaged Property is about to be conveyed by
the Mortgagor (whether by absolute conveyance or by contract of sale, and
whether or not the Mortgagor remains liable thereon) and the Servicer has
knowledge of such prospective conveyance, the Servicer shall effect assumptions
in accordance with the terms of any due-on-sale provision contained in the
related Mortgage Note or Mortgage. The Servicer shall enforce any due-on-sale
provision contained in such Mortgage Note or Mortgage to the extent the
requirements thereunder for an assumption of the Mortgage Loan have not been
satisfied to the extent permitted under the terms of the related Mortgage Note,
unless such provision is not exercisable under applicable law and governmental
regulations or in the Servicer's judgment, such exercise is reasonably likely to
result in legal action by the Mortgagor, or such conveyance is in connection
with a permitted assumption of the related Mortgage Loan. Subject to the
foregoing, the Servicer is authorized to take or enter into an assumption
agreement from or with the Person to whom such property is about to be conveyed,
pursuant to which such person becomes liable under the related Mortgage Note
and, unless prohibited by applicable state law, the Mortgagor remains liable
thereon, PROVIDED THAT the Mortgage Interest Rate with respect to such Mortgage
Loan shall remain unchanged. The Servicer is also authorized to release the
original Mortgagor from liability upon the Mortgage Loan and substitute the new
Mortgagor as obligor thereon. In connection with such assumption or
substitution, the Servicer shall apply such underwriting standards and follow
such practices and procedures as shall be normal and usual for mortgage loans
similar to the Mortgage Loans and as it applies to mortgage loans owned solely
by it. The Servicer shall notify the Trustee that any such assumption or
substitution agreement has been completed by forwarding to the Trustee the
original copy of such assumption or substitution agreement, which copy shall be
added by the Trustee 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. In connection with any
such assumption or substitution agreement, the Mortgage Interest Rate of the
related Mortgage Note and the payment terms shall not be changed. Any fee
collected by the Servicer for entering into an assumption or substitution of
liability agreement will be retained by the Servicer as servicing compensation.

          Notwithstanding the foregoing paragraph or any other provision of this
Agreement, the Servicer shall not be deemed to be in default, breach or any
other violation of its obligations hereunder by reason of any conveyance by the
Mortgagor of the property subject to the Mortgage or any assumption of a
Mortgage Loan by operation of law which the Servicer in good faith determines it
may be restricted by law from preventing, for any reason whatsoever, or if the
exercise of such right would impair or threaten to impair any recovery under any
applicable insurance policy or, in the Servicer's judgment, be reasonably likely
to result in legal action by the Mortgagor.

          Section 5.11 REALIZATION UPON DEFAULTED MORTGAGE LOANS. (a) In the
event that any payment due under any Mortgage Loan is not paid when the same
becomes due and payable, or in the event the Mortgagor fails to perform any
other covenant or obligation under the Mortgage Loan and such failure continues
beyond any applicable grace period, the Servicer shall take such action as it
shall deem to be in the best interest of the Certificateholders and the
Certificate Insurer. With respect to any Charged-off Loan as to which no
satisfactory arrangements can be made for collection of delinquent payments in
accordance with the provisions of Section 5.1, and in accordance with the
standard of care specified in Section 5. 1, in the event that in the Servicer's
reasonable judgment a foreclosure or the taking of title to a related Mortgaged
Property or pursuit of a deficiency judgment against the related borrower is
likely to result in a positive economic benefit to the Trust Fund by creating
Net Liquidation Proceeds, the Servicer shall foreclose upon or otherwise
comparably effect the ownership thereof in the name of Trustee for the benefit
of the Certificateholders and the Certificate Insurer or seek a deficiency
judgment. The Servicer shall give the Trustee and the Certificate Insurer notice
of the election of remedies made pursuant to this Section 5.11. In connection
with any foreclosure or seeking of deficiency judgment or other conversion, the
Servicer shall exercise collection and foreclosure procedures with the same
degree of care and skill as it customarily employs and exercises in collecting
and foreclosing on mortgage loans for its own account and in accordance with
accepted collection and foreclosure practices of prudent lending institutions
and servicers of loans similar to the Mortgage Loans and giving due
consideration to the Certificateholders' and the Certificate Insurer's reliance
on the Servicer. Any amounts advanced or expenses incurred in connection with
such foreclosure, deficiency judgment or other action shall constitute
"Servicing Advances". The foregoing is subject to the proviso that the Servicer
shall not expend its own funds in connection with any foreclosure or to restore
any damaged property unless it shall determine that (i) such foreclosure and/or
restoration will increase the proceeds of liquidation of the Mortgage Loan to
Certificateholders after reimbursement to itself for such expenses and (ii) such
expenses will be recoverable to it through Liquidation Proceeds (respecting
which it shall reimburse itself for such expense prior to the deposit in the
Collection Account of such proceeds). The Servicer shall be entitled to
reimbursement of the Servicing Fee and other amounts due it, if any, to the
extent, but only to the extent, that withdrawals from the Collection Account
with respect thereto are permitted under Section 5.4.

          In the event that title to any Mortgaged Property is acquired in
foreclosure or by deed in lieu of foreclosure (an "REO Property"), the deed or
certificate of sale shall be issued to the Trustee, or to the Servicer in the
name of the Trustee on behalf of the Trustee and the Certificateholders and the
Certificate Insurer. Notwithstanding any such acquisition of title and
cancellation of the related Mortgage Loan, such REO Mortgage Loan shall be
considered to be a Mortgage Loan held in the Trust Fund until such time as the
related Mortgaged Property shall be sold and such REO Mortgage Loan becomes a
Liquidated Loan. Consistent with the foregoing, for purposes of all calculations
hereunder, so long as such REO Mortgage Loan shall be considered to be an
Outstanding Mortgage Loan:

                           (i) It shall be assumed that, notwithstanding that
                  the indebtedness evidenced by the related Mortgage Note shall
                  have been discharged, such Mortgage Note and the related
                  amortization schedule in effect at the time of any such
                  acquisition of title (after giving effect to any previous
                  Curtailments and before any adjustment thereto by reason of
                  any bankruptcy or similar proceeding or any moratorium or
                  similar waiver or grace period) shall be assumed to remain in
                  effect, except that such schedule shall be adjusted to reflect
                  the application of Net REO Proceeds received in any month
                  pursuant to the succeeding clause.

                           (ii) Net REO Proceeds received in any month shall be
                  deemed to have been received first in payment of the accrued
                  interest that remained unpaid on the date that such Mortgage
                  Loan became an REO Mortgage Loan, with the excess thereof, if
                  any, being deemed to have been received in respect of the
                  delinquent principal installments that remained unpaid on such
                  date. Thereafter, Net REO Proceeds received in any month shall
                  be applied to the payment of installments of principal and
                  accrued interest on such Mortgage Loan deemed to be due and
                  payable in accordance with the terms of such Mortgage Note and
                  such amortization schedule. If such Net REO Proceeds exceed
                  the then Unpaid REO Amortization, the excess shall be treated
                  as a Curtailment received in respect of such Mortgage Loan.

          In the event that the Trust Fund acquires any Mortgaged Property as
aforesaid or otherwise in connection with a default or imminent default on a
Mortgage Loan, such Mortgaged Property shall be disposed of by or on behalf of
the Trust Fund within two years after its acquisition thereby unless (a) the
Servicer shall have provided to the Trustee and the Certificate Insurer an
Opinion of Counsel (at the expense of the Trust Fund) to the effect that the
holding by the Trust Fund of such Mortgaged Property subsequent to two years
after its acquisition (and specifying the period beyond such two-year period for
which the Mortgaged Property may be held) will not cause either the Upper-Tier
REMIC or Lower-Tier REMIC to be subject to the tax on prohibited transactions
imposed by Code Section 860F(a)(1), otherwise subject either the Upper-Tier
REMIC or Lower-Tier REMIC to tax or cause either the Upper-Tier REMIC or
Lower-Tier REMIC to fail to qualify as a REMIC at any time that any Certificates
are outstanding, or (b) the Servicer or the Trustee (at the Trust Fund's
expense) shall have applied for, at least 60 days prior to the expiration of
such two-year period, an extension of such two-year period in the manner
contemplated by Code Section 856(e)(3), in which case the two-year period shall
be extended by the applicable period. The Servicer shall further ensure that the
Mortgaged Property is administered so that it constitutes "foreclosure property"
within the meaning of Code Section 860G(a)(8) at all times, that the sale of
such property does not result in the receipt by the Trust Fund of any income
from non-permitted assets as described in Code Section 860F(a)(2)(B), and that
the Trust Fund does not derive any "net income from foreclosure property" within
the meaning of Code Section 860G(c)(2) with respect to such property.

          Any REO Disposition shall be for cash only (unless changes in the
REMIC Provisions made subsequent to the Startup Day allow for a sale for other
consideration).

          In lieu of foreclosing upon any defaulted Mortgage Loan, the Servicer
may, in its discretion, permit the assumption of such Mortgage Loan if, in the
Servicer's judgment, such default is unlikely to be cured and if the assuming
borrower satisfies the Servicer's good faith underwriting guidelines with
respect to mortgage loans owned by the Servicer. In connection with any such
assumption, the Mortgage Interest Rate of the related Mortgage Note and the
payment terms shall not be changed. Any fee collected by the Servicer for
entering into an assumption agreement will be retained by the Servicer as
servicing compensation. Alternatively, the Servicer may encourage the
refinancing of any defaulted Mortgage Loan by the Mortgagor.

          Notwithstanding the foregoing, prior to instituting foreclosure
proceedings or accepting a deed-in-lieu of foreclosure with respect to any
Mortgaged Property, the Servicer shall make, or cause to be made, inspection of
the Mortgaged Property in accordance with the Accepted Servicing Practices and,
with respect to environmental hazards, such procedures as are required by the
provisions of the FNMA's selling and servicing guide applicable to single-family
homes and in effect on the date hereof. The Servicer shall be entitled to rely
upon the results of any such inspection made by others. In cases where the
inspection reveals that such Mortgaged Property is potentially contaminated with
or affected by hazardous wastes or hazardous substances, the Servicer shall
promptly give written notice of such fact to the Certificate Insurer, the
Trustee and each Class A Certificateholder. The Servicer shall not proceed with
any foreclosure proceedings or accept a deed in lieu of foreclosure for such
Mortgaged Property without the prior written consent of the Certificate Insurer.

          In addition to the foregoing, the holder of 50.01% Percentage Interest
or greater of the Class RL Certificates may purchase from the Trust Fund any
Charged-off Loan (or any Mortgage Loan which will imminently become a
Charged-off Loan) by depositing in the Certificate Account an amount equal to
the Loan Repurchase Price; PROVIDED, that such holder of the Class RL
Certificate may only make such repurchases if, following such repurchase, the
aggregate Loan Repurchase Price of all such repurchased Mortgage Loans does not
exceed 10% of the Maximum Collateral Amount.

          (b) Upon becoming aware that a first lien mortgage loan relating to
any Mortgage Loan has come into default or of any action that the related
mortgagee has taken or may take in respect thereof, the Servicer shall,
consistent with the REMIC Provisions, take such actions as it shall deem
necessary or advisable, as shall be normal and usual in its general mortgage
servicing activities and as shall be required or permitted by Accepted Servicing
Practices. In taking such actions, the Servicer may advance such funds as are
necessary to cure such default, maintain such first lien mortgage loan relating
to any Mortgage Loan, acquire the related mortgagee's interest therein or redeem
the related Mortgaged Property. The Servicer, however, shall not be required to
expend its own funds in connection therewith unless it shall determine that such
expense will be recoverable to it. All such expenses shall be included as
Liquidation Expenses pursuant to the definition thereof, and shall be
reimbursable from the related Liquidation Proceeds in accordance with Section
5.4.

          Section 5.12 TRUSTEE TO COOPERATE; RELEASE OF MORTGAGE FILES. (a) Upon
the payment in full of any Mortgage Loan, or the receipt by the Servicer of a
notification that payment in full will be escrowed in a manner customary for
such purposes, the Servicer shall (i) immediately deliver to the Trustee a
notice substantially in the form of the Request for Release of Documents
attached hereto as Exhibit G (which request shall include a statement to the
effect that all amounts received in connection with such payment which are
required to be deposited in the Collection Account pursuant to Section 5.3 have
been or shall be so deposited) and executed by a Servicing Officer and (ii)
request delivery to it of the Mortgage File. Upon receipt of such Request for
Release of Documents, the Trustee, or the Custodian on its behalf, shall
promptly release the related Mortgage File to the Servicer. Upon any such
payment in full, the Servicer is authorized to give, as agent for the Trustee
and the mortgagee under the Mortgage which secured the Mortgage Loan, an
instrument of satisfaction (or assignment of mortgage without recourse)
regarding the property subject to such Mortgage, which instrument of
satisfaction or assignment, as the case may be, shall be delivered to the Person
or Persons entitled thereto against receipt therefor of such payment, it being
understood and agreed that no expenses incurred in connection with such
instrument of satisfaction or assignment, as the case may be, shall be
chargeable to the Collection Account. In connection therewith, the Trustee shall
execute and return to the Servicer any required power of attorney provided to
the Trustee by the Servicer and other required documentation in accordance with
Section 5.1(b). From time to time and as appropriate for the servicing or
foreclosure of any Mortgage Loan and in accordance with Accepted Servicing
Practices, the Trustee shall, upon request of the Servicer and delivery to the
Trustee of a Request for Release of Documents signed by a Servicing Officer,
release, or cause the Custodian to release, the related Mortgage File to the
Servicer and shall execute such documents as shall be necessary to the
prosecution of any such proceedings. Such Request for Release of Documents shall
obligate the Servicer to return the Mortgage File to the Trustee when the need
therefor by the Servicer no longer exists unless the Mortgage Loan shall be
liquidated, in which case, upon receipt of a certificate of a Servicing Officer
similar to the Request for Release of Documents or an additional Request for
Release of Documents hereinabove specified, the Mortgage File shall be delivered
by the Trustee to the Servicer.

          (b) Each Request for Release of Documents may be delivered to the
Trustee (i) via mail or courier, (ii) via facsimile or (iii) by such other
means, including, without limitation, electronic or computer readable medium, as
the Servicer and the Trustee shall mutually agree. The Trustee shall promptly
release the related Mortgage File(s) within five (5) to seven (7) Business Days
of receipt of a properly completed Request for Release of Documents pursuant to
clauses (i), (ii) or (iii) above or such shorter period as may be agreed upon by
the Servicer and the Trustee. Receipt of a Request for Release of Documents
pursuant to clauses (i), (ii) or (iii) above shall be authorization to the
Trustee to release such Mortgage Files, provided the Trustee has determined that
such Request for Release of Documents has been executed, with respect to clauses
(i) or (ii) above, or approved, with respect to clause (iii) above, by a
Servicing Officer of the Servicer, and so long as the Trustee complies with its
duties and obligations under this Agreement. If the Trustee is unable to release
the Mortgage Files within the time frames previously specified, the Trustee
shall immediately notify the Servicer indicating the reason for such delay, but
in no event shall such notification be later than five Business Days after
receipt of a Request for Release of Documents. If the Servicer is required to
pay penalties or damages due solely to the Trustee's negligent failure to
release the related Mortgage File or the Trustee's negligent failure to execute
and release documents in a timely manner, the Trustee shall be liable for such
penalties or damages.

          On each day that the Servicer remits to the Trustee Requests for
Release of Documents pursuant to clauses (ii) or (iii) above, the Servicer shall
also submit to the Trustee a summary of the total amount of such Request for
Release of Documents requested on such day by the same method as described in
such clauses (ii) or (iii) above.

          Section 5.13 SERVICING FEE; SERVICING COMPENSATION. (a) The Servicer
shall be entitled, to pay itself the Servicing Fee pursuant to Section 5.3.

          The aggregate Servicing Fee is reserved for the administration of the
Trust Fund and, in the event of replacement of the Servicer as servicer of the
Mortgage Loans, for the payment of other expenses related to such replacement.
The Trustee, in its capacity as successor servicer, shall not be liable for the
costs of replacement of a predecessor servicer, unless the Trustee is the
predecessor servicer.

          The aggregate Servicing Fee shall be offset as provided in Section
5.19. The Servicer shall be required to pay all expenses incurred by it in
connection with its servicing activities hereunder (including maintenance of the
hazard insurance required by Section 5.5) and shall not be entitled to
reimbursement therefor except as specifically provided herein.

          (b) Servicing compensation in the form of assumption fees, late
payment charges, tax service fees, fees for statement of account or payoff of
the Mortgage Loan (to the extent permitted by applicable law) or otherwise shall
be retained by the Servicer and are not required to be deposited in the
Collection Account.

          Section 5.14 REPORTS TO THE TRUSTEE; COLLECTION ACCOUNT STATEMENTS.
Not later than 15 days after each Distribution Date, the Servicer shall provide
to the Trustee, the Certificate Insurer, the Underwriter and the Depositor a
statement, certified by a Servicing Officer, setting forth the status of the
Collection Account as of the close of business on the last day of the
immediately preceding calendar month, stating that all distributions required by
this Agreement to be made by the Servicer on behalf of the Trustee have been
made (or if any required distribution has not been made by the Servicer,
specifying the nature and status thereof) and showing, for the period covered by
such statement, the aggregate of deposits into and withdrawals from the
Collection Account for each category of deposit specified in Section 5.3 and
each category of withdrawal specified in Section 5.4 and the aggregate of
deposits into the Certificate Account specified in Section 6.1(c). Copies of
such statement shall be provided by the Trustee to any Certificateholder upon
request.

          Section 5.15 ANNUAL STATEMENT AS TO COMPLIANCE. The Servicer will
deliver to the Trustee, the Certificate Insurer, the Underwriter, and each of
the Rating Agencies not later than the last day of the fifth month subsequent to
the end of the Servicer's fiscal year, beginning in 1998, an Officers'
Certificate stating as to each signer thereof, that (i) a review of the
activities of the Servicer during the preceding calendar year and of its
performance under this Agreement has been made under such officer's supervision,
and (ii) to the best of such officer's knowledge, based on such review, the
Servicer has fulfilled all 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 and (iii) the Servicer has in full force and effect a blanket fidelity
bond and an errors and omissions insurance policy in accordance with the terms
and requirements of Section 5.8 hereof. Such Officers' Certificate shall be
accompanied by the statement described in Section 5.16 of this Agreement. Copies
of such statement shall, upon request, be provided to any Certificateholder by
the Servicer, or by the Trustee at the Servicer's expense if the Servicer shall
fail to provide such copies.

          Section 5.16 ANNUAL INDEPENDENT PUBLIC ACCOUNTANTS' SERVICING REPORT.
Not later than the last day of the fifth month subsequent to the end of the
Servicer's fiscal year, beginning in 1998, the Servicer, at its expense, shall
cause a firm of nationally recognized independent public accountants to furnish
a statement to the Trustee, the Certificate Insurer, the Underwriter, each of
the Rating Agencies, each Certificateholder to the effect that, on the basis of
an examination of certain documents and records relating to the servicing of the
mortgage loans being serviced by the Servicer under pooling and servicing
agreements similar to this Agreement (which agreements shall be described in a
schedule to such statement), conducted substantially in compliance with the
Uniform Single Attestation Program for Mortgage Bankers, such firm is of the
opinion that such servicing has been conducted in compliance with this
Agreement. Copies of such statement shall, upon request, be provided to
Certificateholders by the Servicer, or by the Trustee at the Servicer's expense
if the Servicer shall fail to provide such copies. For purposes of such
statement, such firm may conclusively presume that any pooling and servicing
agreement which governs mortgage pass-through certificates offered by the
Depositor (or any predecessor or successor thereto) in a registration statement
under the Securities Act of 1933, as amended, is similar to this Agreement,
unless such other pooling and servicing agreement expressly states otherwise.

          Section 5.17 [Reserved].

          Section 5.18 REPORTS TO BE PROVIDED BY THE Servicer. The Servicer
agrees to make available on a reasonable basis to the Certificate Insurer a
knowledgeable financial or accounting officer for the purpose of answering
reasonable questions respecting recent developments affecting the Servicer or
the financial statements of the Servicer and to permit the Certificate Insurer
to inspect the Servicer's servicing facilities during normal business hours for
the purpose of satisfying the Certificate Insurer that the Servicer has the
ability to service the Mortgage Loans in accordance with this Agreement.

          Section 5.19 ADJUSTMENT OF SERVICING COMPENSATION IN RESPECT OF
PREPAID MORTGAGE LOANS. The aggregate amount of the Servicing Fees that the
Servicer shall be entitled to receive with respect to all of the Mortgage Loans
and each Distribution Date shall be offset on such Distribution Date by an
amount equal to the aggregate Prepayment Interest Shortfall with respect to all
Mortgage Loans which were subjects of Principal Prepayments during the
Collection Period applicable to such Distribution Date. The amount of any offset
against the aggregate Servicing Fee with respect to any Distribution Date under
this Section 5.19 shall be limited to the aggregate amount of the Servicing Fees
otherwise payable to the Servicer and any Subservicer (without adjustment on
account of Prepayment Interest Shortfalls) with respect to (i) scheduled
payments having the Due Date occurring in Collection Period applicable to such
Distribution Date, and (ii) Principal Prepayments and Liquidation Proceeds
applicable to such Distribution Date, and the rights of the Certificateholders
to the offset of the aggregate Prepayment Interest Shortfalls shall not be
cumulative.

          Section 5.20 DELINQUENCY INTEREST ADVANCES. By 3:00 p.m. New York time
on each Servicer Remittance Date, the Servicer shall make a Delinquency Interest
Advance with respect to delinquent interest on each Mortgage Loan which was a
Delinquent Mortgage Loan with respect to the related Collection Period by
depositing such Delinquency Interest Advance into the Certificate Account;
PROVIDED, HOWEVER, that the Servicer will not be required to make any
Delinquency Interest Advance if the Servicer has determined in accordance with
Accepted Servicing Practices that all amounts which it expects to receive with
respect to such Mortgage Loan have been received. Such deposit may be made in
whole or in part or in part from funds in the Collection Account being held for
future distribution or withdrawal on or in connection with Distribution Dates in
subsequent months. Any funds being held for future distribution to
Certificateholders and so used shall be replaced by Servicer from its own funds
by deposit in the Certificate Account on or before the Business Day preceding
any such future Servicer Remittance Date to the extent that funds in the
Certificate Account on such Servicer Remittance Date shall be less than payments
to Certificateholders required to be made on such date.

          The Servicer shall be permitted to reimburse itself for any
Delinquency Interest Advance from any subsequent collections or Net Liquidation
Proceeds relating to such Mortgage Loan. If not theretofore recovered by the
Servicer, and the Servicer determines that any Delinquency Interest Advance was
a Nonrecoverable Advance, such Delinquency Interest Advance shall be recoverable
pursuant to Section 5.4 hereof.

          Section 5.21 [RESERVED].

          Section 5.22 MAINTENANCE OF CORPORATE EXISTENCE AND LICENSES; MERGER
OR CONSOLIDATION OF THE SERVICER. (a) The Servicer will keep in full effect its
existence, rights and franchises as a corporation, will obtain and preserve its
qualification to do business as a foreign corporation in each jurisdiction
necessary to protect the validity and enforceability of this Agreement or any of
the Mortgage Loans and to perform its duties under this Agreement and will
otherwise operate its business so as to cause the representations and warranties
under Section 3.1 to be true and correct at all times under this Agreement.

          (b) Any Person into which the Servicer may be merged or consolidated,
or any corporation resulting from any merger, conversion or consolidation to
which the Servicer shall be a party, or any Person succeeding to the business of
the Servicer, shall be an established mortgage loan servicing institution
acceptable to the Certificate Insurer that has a net worth of at least
$15,000,000 and is a Permitted Transferee, and in all events shall be the
successor of the Servicer 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. The Servicer shall send notice of any such merger or
consolidation to the Trustee and the Certificate Insurer.

          Section 5.23 ASSIGNMENT OF AGREEMENT BY SERVICER; SERVICER NOT TO
RESIGN. The Servicer shall not assign this Agreement nor resign from the
obligations and duties hereby imposed on it except by mutual written consent of
the Servicer, the Seller, the Depositor, the Certificate Insurer and the Trustee
or upon the determination that the Servicer's duties hereunder are no longer
permissible under applicable law and that such incapacity cannot be cured by the
Servicer without the incurrence, in the reasonable judgment of the Certificate
Insurer, of unreasonable expense. Any such determination that the Servicer's
duties hereunder are no longer permissible under applicable law permitting the
resignation of the Servicer shall be evidenced by a written Opinion of Counsel
(who may be counsel for the Servicer) to such effect delivered to the Trustee,
the Seller, the Depositor and the Certificate Insurer. No such resignation shall
become effective until the Trustee or a successor appointed in accordance with
the terms of this Agreement has assumed the Servicer's responsibilities and
obligations hereunder in accordance with Section 7.2. The Servicer shall provide
the Trustee, each of the Rating Agencies and the Certificate Insurer with 30
days' prior written notice of its intention to resign pursuant to this Section
5.23.

          Section 5.24 INFORMATION REPORTS TO BE FILED BY THE SERVICER. The
Servicer or Subservicers 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.

                           DISTRIBUTIONS AND PAYMENTS

          Section 6.1 ESTABLISHMENT OF CERTIFICATE ACCOUNT; DEPOSITS TO THE
CERTIFICATE ACCOUNT. (a) The Trustee shall establish and maintain the
Certificate Account which shall be titled "Certificate Account, Bankers Trust
Company, as trustee for the registered holders of Preferred Credit Asset-Backed
Certificates, Series 1997-1 and MBIA Insurance Corporation as Certificate
Insurer" and which shall be an Eligible Account. Notice of the establishment of
the Certificate Account shall be promptly provided in writing to each of the
Servicer, the Rating Agencies and the Certificate Insurer.

          (b) Subject to Section 6.6 hereof, the Servicer may direct the Trustee
in writing to invest the funds in the Certificate Account only in Permitted
Investments which mature not later than the Business Day prior to the
Distribution Date. No Permitted Investment shall be sold or disposed of at a
gain prior to maturity unless the Servicer has delivered to the Trustee and the
Certificate Insurer an Opinion of Counsel (at the Servicer's expense) that such
sale or disposition will not cause the Lower-Tier REMIC or Upper-Tier REMIC to
be subject to the tax on income from prohibited transactions imposed by Code
Section 860F(a)(1), otherwise subject the Lower-Tier REMIC or Upper-Tier REMIC
to tax or cause the Lower-Tier REMIC or Upper-Tier REMIC to fail to qualify as a
REMIC. All income (other than any gain from a sale or disposition of the type
referred to in the preceding sentence) realized from any such Permitted
Investment shall be for the benefit of the Servicer as additional servicing
compensation. The amount of any losses incurred in respect of any such
investments shall be deposited in the Certificate Account by the Servicer out of
its own funds immediately as realized.

          (c) on each Servicer Remittance Date, the Servicer shall cause to be
deposited in the Certificate Account, from related funds on deposit in the
Collection Account, an amount equal to the related Servicer Remittance Amount.

          (d) The Trustee shall make deposits to the Certificate Account
pursuant to Section 6.11 and 6.12.

          Section 6.2 PERMITTED WITHDRAWALS FROM THE CERTIFICATE ACCOUNT. The
Trustee shall, in accordance with the Servicer's written directions to the
Trustee as described in Section 6.5, withdraw or cause to be withdrawn funds
from the Certificate Account for the following purposes:

                           (i)      to effect the distributions described in
                  Section 6.5;

                           (ii)     to pay the Servicer any interest earned on
                  or investment income  earned with respect to funds in
                  the Certificate Account;

                           (iii)    to return to the Collection Account any
                  amount deposited in the Certificate Account that was
                  not required to be deposited therein;

                           (iv)     to pay to itself the Trustee Fee in
                  accordance with Section 9.5; and

                           (v)      to clear and terminate the Certificate
                  Account upon termination of the Trust Fund pursuant
                  to Article VIII.

          The Trustee shall keep and maintain a separate accounting for
withdrawals from the Certificate Account pursuant to each of subclauses (i)
through (vi) listed above.

          Section 6.3 COLLECTION OF MONEY. Except as otherwise expressly
provided herein, the Trustee may demand payment or delivery of all money and
other property payable to or receivable by the Trustee pursuant to this
Agreement, including, but not limited to, (a) all payments due on the Mortgage
Loans in accordance with the respective terms and conditions of such Mortgage
Loans and required to be paid over to the Trustee by the Servicer or by any
Subservicer and (b) Insured Payments. The Trustee shall hold all such money and
property received by it, as part of the Trust Fund and shall apply it as
provided in this Agreement.

          Section 6.4 THE CERTIFICATE INSURANCE POLICY. (a) Subject to receipt
of the report referenced in Section 6.5, within three Business Days after each
Determination Date, the Trustee shall determine with respect to the immediately
following Distribution Date the amount to be on deposit in the Certificate
Account on such Distribution Date less the amounts described in clauses (i) and
(ii) of Section 6.5 for the related Distribution Date, and not including the
amount of any Insured Payment which is required to be deposited in the related
Certificate Account for such Distribution Date. The amounts described in the
preceding sentence with respect to each Distribution Date are the "Available
Funds" for such Distribution Date.

          (b) If on any Distribution Date there is an Available Funds Shortfall,
the Trustee shall complete a Notice in the form of Exhibit A to the Certificate
Insurance Policy and submit such Notice to the Certificate Insurer no later than
12:00 noon New York City time on the third Business Day preceding such
Distribution Date as a claim for an Insured Payment in an amount equal to such
Available Funds Shortfall.

          (c) The Trustee shall establish a separate Eligible Account for the
benefit of Holders of the Certificates and the Certificate Insurer referred to
herein as the "Certificate Insurance Payments Account" over which the Trustee
shall have exclusive control and sole right of withdrawal. The Trustee shall
deposit upon receipt any amount paid under the Certificate Insurance Policy in
the Certificate Insurance Payments Account and distribute such amount only for
purposes of payment to Certificateholders of the portion of the Insured
Distribution Amount for which a claim was made and such amount may not be
applied to satisfy any costs, expenses or liabilities of the Servicer, the
Trustee or the Trust Fund. Amounts paid under the Certificate Insurance Policy,
to the extent needed to pay the Insured Distribution Amount, shall be
transferred by the Trustee from the Certificate Insurance Payments Account to
the Certificate Account on the related Distribution Date and disbursed by the
Trustee to the Class A Certificateholders in accordance with Section 6.5. It
shall not be necessary for payments made under the Certificate Insurance Policy
to be made by checks or wire transfers separate from other amounts distributed
pursuant to Section 6.5. However, the amount of any payment of principal of or
interest on the Class A Certificates to be paid from funds transferred from the
Certificate Insurance Payments Account shall be noted as provided in paragraph
(d) below. Funds held in the Certificate Insurance Payments Account shall not be
invested. Any funds remaining in the Certificate Insurance Payments Account on
the first Business Day following a Distribution Date shall be returned to the
Certificate Insurer by the Trustee pursuant to the written instructions of the
Certificate Insurer by the end of such Business Day.

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

          (e) In the event that the Trustee has received a certified copy of an
order of the appropriate court that any amount distributed on the Class A
Certificates, including any amounts represented by an Insured Payment, has been
voided in whole or in part as a preference payment under applicable bankruptcy
law that constitutes a Preference Amount under the Certificate Insurance Policy,
the Trustee shall so notify the Certificate Insurer, shall comply with the
provisions of the Certificate Insurance Policy to obtain payment by the
Certificate Insurer of such voided amount distributed, and shall, at the time it
provides notice to the Certificate Insurer, notify, by mail to Class A
Certificateholders of the affected Class A Certificates that, in the event any
Class A Certificateholder's amount distributed is so recovered, such Class A
Certificateholder will be entitled to payment pursuant to the Certificate
Insurance Policy, a copy of which shall be made available through the Trustee,
the Certificate Insurer or the Certificate Insurer's Fiscal Agent, if any, and
the Trustee shall furnish to the Certificate Insurer or its Fiscal Agent, if
any, its records evidencing the payments which have been made by the Trustee and
subsequently recovered from Certificateholders, and dates on which such payments
were made.

          (f) The Trustee shall promptly notify the Certificate Insurer of any
proceeding or the institution of any action, of which a Responsible Officer of
the Trustee has actual knowledge, seeking the avoidance as a preferential
transfer under applicable bankruptcy, insolvency, receivership or similar law (a
"Preference Claim") of any distribution made with respect to the Certificates.
Each Certificateholder, by its purchase of Certificates, the Seller, the
Depositor, the Servicer and the Trustee agree that, the Certificate Insurer (so
long as no Certificate Insurer Default exists) may at any time during the
continuation of any proceeding relating to a Preference Claim direct all matters
relating to such Preference Claim, including, without limitation, (i) the
direction of any appeal of any order relating to such Preference Claim and (ii)
the posting of any surety, supersedeas or performance bond pending any such
appeal. In addition and without limitation of the foregoing, the Certificate
Insurer shall be subrogated to, and each Certificateholder, the Servicer, the
Seller, the Depositor and the Trustee hereby delegate and assign to the
Certificate Insurer, to the fullest extent permitted by law, the rights of the
Servicer, the Trustee, the Depositor, the Seller and each Certificateholder in
the conduct of any such Preference Claim, including, without limitation, all
rights of any party to any adversary proceeding or action with respect to any
court order issued in connection with any such Preference Claim.

          Section 6.5 DISTRIBUTIONS. No later than 12:00 noon California time on
the Business Day following the Determination Date, the Servicer shall deliver to
the Trustee and the Certificate Insurer a report in computer-readable form
(including electronic transmission) containing such information as to the
Mortgage Loans as of such date and such other information as the Trustee and the
Certificate Insurer may reasonably require. With respect to funds on deposit in
the Certificate Account (inclusive of amounts transferred from the Certificate
Insurance Payments Account, the Pre-Funding Account and the Capitalized Interest
Account), on each Distribution Date, the Trustee shall make the following
allocations, disbursements and transfers in the following order of priority, and
each such allocation, transfer and disbursement shall be treated as having
occurred only after all preceding allocations, transfers and disbursements have
occurred:

                  (i)    to the Certificate Insurer, the Certificate
Insurance Policy Premium Amount;

                  (ii)   to the Trustee, an amount equal to the Trustee
Fees then due to it;

                  (iii)  to the Certificate Insurer, the lesser of (x) an amount
equal to (i) the Available Funds MINUS (ii) the Insured Distribution Amount for
such Distribution Date and (y) the outstanding Reimbursement Amount, if any, as
of such Distribution Date;

                  (iv)   to each Class A Certificateholder, an amount
equal to the related Class A Interest Distribution Amount;

                  (v)    to each of the Class A Certificateholders, an amount 
equal to the lesser of (a) the related Class A Principal Distribution Amount and
(b) the amount remaining in the Certificate Account after distributions pursuant
to clauses (i) through (iiv) above, as follows:

                           (1)      to the Class A-1 Certificateholders until
                  the Class A-1 Principal  Balance has been reduced to
                  zero;

                           (2)      to the Class A-2 Certificateholders until
                  the Class A-2 Principal  Balance has been reduced to
                  zero;

                           (3)      to the Class A-3 Certificateholders until
                  the Class A-3 Principal  Balance has been reduced to
                  zero; and

                           (4)      to the Class A-4 Certificateholders until
                  the Class A-4 Principal  Balance has been reduced to
                  zero;

                           (5)      to the Class A-5 Certificateholders until
                  the Class A-5 Principal  Balance has been reduced to
                  zero; and

                           (6)      to the Class A-6 Certificateholders until
                  the Class A-6 Principal  Balance has been reduced to
                  zero;

          (vi) to the Class B Certificateholders, the lesser of (a) the Class B
Accrued Interest and (b) the amount remaining in the Certificate Account after
distributions pursuant to clauses (i) through (v) above; however, any unpaid
Class B Accrued Interest for such Distribution Date shall be added to the Class
B Principal Balance.

          (vii) to the Class B Certificateholders, an amount equal to the
Overcollateralization Reduction Amount, which shall be applied as a reduction of
the Class B Principal Balance;

          (viii) to the Class B Certificateholders, on any Distribution Date an
amount equal to the lesser of (a) the Class B Accrued Interest and (b) the
amount remaining in the Certificate Account after distributions pursuant to
clauses (i) through (v) above.

          (ix) to the Holders of the Class RU Certificates, the amount remaining
on such Distribution Date, if any;

PROVIDED, HOWEVER, that if, on any Distribution Date, (x) the Certificate
Insurer is then in default under the Certificate Insurance Policy relating to
the Mortgage Loans and (y) an Overcollateralization Deficit exists, then any
distribution of the Class A Principal Distribution Amount on such Distribution
Date shall be made PRO RATA to the holders of each of the Class A Certificates
until the Class A Principal Balance has been reduced to zero.

          Notwithstanding clause (iv) above, the aggregate amounts distributed
on all Distribution Dates to the Holders of the Class A Certificates on account
of the related Class A Principal Distribution Amount shall not exceed the
related Original Class A Principal Balance.

          Section 6.6 INVESTMENT OF ACCOUNTS. (a) So long as no Event of Default
shall have occurred and be continuing and consistent with any requirements of
the Code, all or a portion of any Account (other than the Certificate Insurance
Payments Account) held by the Trustee shall be invested and reinvested by the
Trustee, as directed in writing by the Servicer (with respect to the Collection
Account and the Certificate Account) or the Seller (with respect to the
Pre-Funding Account and the Capitalized Interest Account) in one or more
Permitted Investments bearing interest or sold at a discount. If an Event of
Default shall have occurred and be continuing or if the Servicer or the Seller
do not provide investment directions, the Trustee shall invest all Accounts in
Permitted Investments described in paragraph (d) of the definition of Permitted
Investments. No such investment in any Account shall mature later than the
Business Day immediately preceding the next Distribution Date (except that if
such Permitted Investment is an obligation of the Trustee, then such Permitted
Investment shall mature not later than such Distribution Date). Notwithstanding
anything to the contrary in this Section 6.6(a), all amounts received under the
Certificate Insurance Policy shall remain uninvested.

          (b) If any amounts are needed for disbursements from any Account
(other than the Certificate Insurance Payments Account) held by the Trustee and
sufficient uninvested funds are not available to make such disbursement, the
Trustee shall cause to be sold or otherwise converted to cash a sufficient
amount of the investments in such Account. The Trustee shall not be liable for
any investment loss or other charge resulting therefrom unless the Trustee's
failure to perform in accordance with this Section 6.6 is the cause of such loss
or charge or the Trustee is the obligor of the related investment.

          (c) Subject to Section 9.1 hereof, the Trustee shall not in any way be
held liable by reason of any insufficiency in any Account held by the Trustee
resulting from any investment loss on any Permitted Investment included therein
(except as provided in subsection (b) of this Section 6.6).

          (d) So long as no Event of Default shall have occurred and be
continuing, all net income and gain realized from investment of, and all
earnings on, funds deposited in the Collection Account shall be for the benefit
of the Servicer as servicing compensation (in addition to the Servicing Fee).
The Servicer shall deposit in the Collection Account and the Certificate Account
and the Seller shall deposit in the Pre-Funding Account and the Capitalized
Interest Account, the amount of any loss incurred in respect of any Permitted
Investment held therein which is in excess of the income and gain thereon
immediately upon realization of such loss, without any right to reimbursement
therefor from its own funds.

          Section 6.7 REPORTS BY TRUSTEE. (a) on each Distribution Date the
Trustee shall, based on a report delivered to it by the Servicer on the
Determination Date, as described in Section 6.5 hereof, provide to each Holder,

                  Residual Certificates;

                           (ii) the amount of such distributions allocable to

                  included therein;

shall furnish a report to the Certificate Insurer and to each Holder of record
if so requested in writing at any time during each calendar year as to the
aggregate of amounts reported pursuant to (i), (ii) and (iii) with respect to
the Certificates for such calendar year.

          (b) The Trustee shall, on behalf of the Trust, cause to be filed with
the Securities and Exchange Commission any periodic reports required to be filed
under the provisions of the Securities Exchange Act of 1934, as amended, and the
rules and regulations of the Securities and Exchange Commission thereunder. Upon
the request of the Trustee, each of the Depositor and the Servicer shall
cooperate with the Trustee in the preparation of any such report and shall
provide to the Trustee in a timely manner all such information or documentation
as the Trustee may reasonably request in connection with the performance of its
duties and obligations under this Section 6.7(b).

          (c) All distributions made to the Certificateholders according to
Class or type of Certificate on each Distribution Date will be made on a pro
rata basis among the Certificateholders as of the next preceding Record Date
based on the Percentage Interest represented by their respective Certificates,
and shall be made by wire transfer of immediately available funds to the account
of such Certificateholder at a bank or other entity having appropriate

SUBROGATION. Anything herein to the contrary notwithstanding, any payment with
respect to principal of or interest on the Certificates which is made with

on the part of the Certificate Insurer, the Depositor, the Servicer, the Trustee
or the Certificate Registrar (i) to the extent the Certificate Insurer makes
payments, directly or indirectly, on account of principal of or interest on the

be fully subrogated to, and each Certificateholder, the Depositor, the Servicer
and the Trustee hereby delegate and assign to the Certificate Insurer, to the

principal and interest from the Trust Fund, including, without limitation, any
amounts due to the Certificateholders in respect of securities law violations
arising from the offer and sale of the Certificates, and (ii) the Certificate

          (a) No later than the Closing Date, the Trustee shall establish and
maintain with itself one or more segregated trust accounts that are Eligible
Accounts, which shall be titled "Pre-Funding Account, Bankers Trust Company, as
trustee for the registered holders of Preferred Credit Asset--Backed

Insurer" (the "Pre-Funding Account"). On the Closing Date, the Trustee shall
from the proceeds of the sale of the Class A Certificates deposit in the
Pre-Funding Account and retain therein the Original Pre-Funded Amount. Funds
deposited in the Pre-Funding Account shall be held in trust by the Trustee for
the Holders of the Certificates and the Certificate Insurer for the uses and
purposes set forth herein. For federal income tax purposes, the Depositor shall
be the owner of the Pre-Funding Account and shall report all items of income,

investment of funds deposited in the Pre-Funding Account shall be transferred to
the Capitalized Interest Account on the Business Day immediately preceding each
Distribution Date.

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

                           (i) On any Subsequent Transfer Date, the Trustee,
                  upon written direction from the Depositor, shall withdraw from
                  the Pre-Funding Account and pay to the Depositor an amount
                  equal to 97% of the Principal Balances of the Subsequent
                  Mortgage Loans transferred and assigned to the Trustee on such
                  Subsequent Transfer Date upon satisfaction of the conditions
                  set forth in Sections 2.3 and 2.9(b) above with respect to
                  such transfer and assignment; and

                           (ii) if the Pre-Funded Amount has not been reduced to
                  zero during the Pre-Funding Period, or if the Pre-Funded
                  Amount has been reduced to $50,000 or less on the immediately
                  succeeding Determination Date, the Trustee shall deposit into
                  the Certificate Account any amounts remaining in the
                  Pre-Funding Account.

          Section 6.12 CAPITALIZED INTEREST ACCOUNTS.

          (a) No later than the Closing Date, the Trustee shall establish and
maintain with itself a separate, aggregated trust account, which shall be an
Eligible Account, titled "Capitalized Interest Account, Bankers Trust Company,
as trustee for the registered holders of Preferred Credit Asset--Backed
Certificates, Series 1997-1 and MBIA Insurance Corporation, as Certificate
Insurer" (the "Capitalized Interest Account"). On the Closing Date, the Trustee
shall from proceeds of the sale of the Class A Certificates deposit in the
Capitalized Interest Account and retain therein the Capitalized Interest Amount.
In addition, the Trustee shall deposit into the Capitalized Interest Account all
income and gain on investments in the Pre-Funding Account pursuant to Section
6.11. Funds deposited in the Capitalized Interest Account shall be held in trust
by the Trustee for the Holders of the Certificates and the Certificate Insurer
for the uses and purposes set forth herein. For federal income tax purposes, the
Depositor shall be the owner of the Capitalized Interest Account and shall
report all items of income, deduction, gain or loss arising therefrom. The
Depositor shall deposit in the Capitalized Interest 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.

          (b) On each of the first three Distribution Dates, the Trustee shall
withdraw from the Capitalized Interest Account and deposit in the Certificate
Account the related Capitalized Interest Addition.

          (c) On each Determination Date following the conveyance of a
Subsequent Mortgage Loan to the Trustee, funds on deposit in the Capitalized
Interest Account in an amount equal to the product of (i) the Principal Balance
of such Subsequent Mortgage Loan and (ii) the weighted average of the Class A-1
Pass-Through Rate, the Class A-2 Pass-Through Rate, the Class A-3 Pass-Through
Rate, the Class A-4 Pass-Through Rate, the Class A-5 Pass-Through Rate and the
Class A-6 Pass-Through Rate, and (iii) a fraction, the numerator of which is the
number of days from the Subsequent Cut-Off Date to June 1, 1997 and the
denominator of which is 360, shall be remitted immediately to the Depositor.

          (d) Upon the earliest of (i) termination of the Trust Fund in
accordance with Section 8.1 or (ii) the first Remittance Day following the end
of the Pre-Funding Period, any amount remaining on deposit in the Capitalized
Interest Account after distributions pursuant to Section 6.12(b) above shall be
withdrawn by the Trustee and paid to the Depositor.

                                   ARTICLE VII

                                     DEFAULT

          Section 7.1 EVENTS OF DEFAULT. (a) In case one or more of the
following Events of Default by the Servicer shall occur and be continuing, that
is to say:

                           (i) any failure by the Servicer to remit to the
                  Trustee any payment, other than a Servicing Advance, required
                  to be made by the Servicer under the terms of this Agreement
                  which continues unremedied for two days after the date upon
                  which such payment was required to be made;

                           (ii) the failure by the Servicer to make any required
                  Servicing Advance which failure continues unremedied for a
                  period of 30 days after the date on which written notice of
                  such failure, requiring the same to be remedied, shall have
                  been given to the Servicer by the Trustee or to the Servicer
                  and the Trustee by any Certificateholder or the Certificate
                  Insurer;

                           (iii) any failure on the part of the Servicer duly to
                  observe or perform in any material respect any other of the
                  covenants or agreements on the part of the Servicer contained
                  in this Agreement or in the Certificate Insurance Agreement,
                  or the failure of any representation and warranty made
                  pursuant to Section 3.1 to be true and correct which continues
                  unremedied for a period of 30 days (or 15 days in the case of
                  a failure to pay the premium for any insurance policy which is
                  required to be maintained under this Agreement) after the date
                  on which written notice of such failure, requiring the same to
                  be remedied, shall have been given to the Servicer, as the
                  case may be, by the Depositor or the Trustee or to the
                  Servicer and the Trustee by any Certificateholder or the
                  Certificate Insurer;

                           (iv) a decree or order of a court or agency or
                  supervisory authority having jurisdiction in an involuntary
                  case under any present or future federal or state bankruptcy,
                  insolvency or similar law or for the appointment of a
                  conservator or receiver or liquidator in any insolvency,
                  readjustment of debt, marshalling of assets and liabilities or
                  similar proceedings, or for the winding-up or liquidation of
                  its affairs, shall have been entered against the Servicer and
                  such decree or order shall have remained in force,
                  undischarged or unstayed for a period of 60 days;

                           (v) the Servicer shall consent to the appointment of
                  a conservator or receiver or liquidator in any insolvency,
                  readjustment of debt, marshalling of assets and liabilities or
                  similar proceedings of or relating to the Servicer or of or
                  relating to all or substantially all of the Servicer's
                  property;

                           (vi) the Servicer shall admit in writing its
                  inability to pay its debts as they become due, file a petition
                  to take advantage of any applicable insolvency or
                  reorganization statute, make an assignment for the benefit of
                  its creditors, or voluntarily suspend payment of its
                  obligations; or

                           (vii) a Servicer Trigger Event that the
                  Certificate Insurer declares is an  Event of Default.

          (b) If an Event of Default described in this Section shall occur,
then, and in each and every such case, so long as such Event of Default shall
not have been remedied or waived pursuant to Section 7.3: (1) with respect
solely to clause (i) above, if such payment is not made on the second day after
the date upon which such payment was required to be made, the Trustee shall give
immediate telephonic notice of such failure to a Responsible Officer of the
Servicer and to the Certificate Insurer and the Trustee shall terminate all of
the rights and obligations of the Servicer under this Agreement and the Trustee,
or a successor Servicer appointed in accordance with Section 7.2, shall
immediately make such payment and assume, pursuant to Section 7.2, the duties of
a successor Servicer and (2) with respect to clauses (ii), (iii), (iv), (v),
(vi) and (vii) above, the Trustee shall, but only at the direction of the
Certificate Insurer or the Majority Certificateholders and with the prior
written consent of the Certificate Insurer, by notice in writing to the Servicer
and a Responsible Officer of the Trustee, and in addition to whatever rights
such Certificateholders may have at law or equity to damages, including
injunctive relief and specific performance, terminate all the rights and
obligations of the Servicer under this Agreement and in and to the Mortgage
Loans and the proceeds thereof, as servicer.

          Upon receipt by the Servicer of such written notice, all authority and
power of the Servicer under this Agreement, whether with respect to the Mortgage
Loans or otherwise, shall, subject to Section 7.2, pass to and be vested in the
Trustee or its designee approved by the Certificate Insurer and the Trustee is
hereby authorized and empowered to execute and deliver, on behalf of the
Servicer, as attorney-in-fact or otherwise, at the expense of the Servicer, any
and all documents and other instruments and do or cause to be done all other
acts or things necessary or appropriate to effect the purposes of such notice of
termination, including, but not limited to, the transfer and endorsement or
assignment of the Mortgage Loans and related documents. The Servicer agrees to
cooperate (and pay any related costs and expenses) with the Trustee in effecting
the termination of the Servicer's responsibilities and rights hereunder,
including, without limitation, the transfer to the Trustee or its designee for
administration by it of all amounts which shall at the time be credited by the
Servicer to the Collection Account or the Servicer Account or thereafter
received with respect to the Mortgage Loans. The Trustee shall promptly notify
the Certificate Insurer, each Certificateholder and each of the Rating Agencies
of the occurrence of an Event of Default.

          (c) Upon the occurrence of a Servicer Trigger Event, the Certificate
Insurer may require that an audit of the Servicer's servicing practices be
performed, at the expense of the Seller, by a Person selected by the Certificate
Insurer. The Servicer shall promptly provide the Certificate Insurer the written
results of such audit. If, upon being furnished with the results of such audit,
the Certificate Insurer reasonably concludes that the Servicer's servicing
practices have not been in compliance with the Accepted Servicing Practices, and
the Servicer cannot cure such audit discrepancies within 30 days of the delivery
of such audit to the Certificate Insurer and the Servicer, the Certificate
Insurer may declare an Event of Default and may remove the Servicer by giving
written notice of such determination to the Seller, the Servicer and the
Trustee.

          As used above, "SERVICER TRIGGER EVENT" means (a) prior to the
Distribution Date in March, 2002, Total Expected Losses exceed 7.75 % of the
Maximum Collateral Amount or (b) on and after the Distribution Date in March,
2002, Total Expected Losses exceed 12.00 % of the Maximum Collateral Amount.

          Section 7.2 TRUSTEE TO ACT; APPOINTMENT OF Successor. (a) On and after
the time the Servicer receives a notice of termination pursuant to Section 7.1,
or the Trustee receives the resignation of the Servicer evidenced by an Opinion
of Counsel pursuant to Section 5.23, or the Servicer is removed as Servicer
pursuant to Article VII, in which event the Trustee shall promptly notify the
Certificate Insurer and each of the Rating Agencies, except as otherwise
provided in Section 7.1, the Trustee shall be the successor in all respects to
the Servicer in its capacity as servicer under this Agreement and the
transactions set forth or provided for herein and shall be subject to all the
responsibilities, duties and liabilities relating thereto placed on the Servicer
by the terms and provisions hereof arising on or after the date of succession;
PROVIDED, HOWEVER, that the Trustee shall not be liable for any actions or the
representations and warranties of any servicer prior to it and including,
without limitation, the obligations of the Servicer set forth in Section 3.4.
The Trustee, as successor servicer, or any other successor servicer shall be
obligated to pay Compensating Interest pursuant to Section 6.9 hereof; the
Trustee, as successor servicer shall be obligated to make advances pursuant to
Section 5.20 unless, and only to the extent the Trustee, as successor servicer
or any other successor servicer determines reasonably and in good faith that
such advances would not be recoverable, such determination to be evidenced by a
certification of a Responsible Officer of the Trustee, as successor servicer or
any other successor servicer delivered to the Certificate Insurer.

          (b) Notwithstanding the above, the Trustee may, if it shall be
unwilling to so act, or shall, if it is unable to so act or if the Majority
Certificateholders with the consent of the Certificate Insurer or the
Certificate Insurer so requests in writing to the Trustee, appoint, pursuant to
the provisions set forth in paragraph (c) below, or petition a court of
competent jurisdiction to appoint, any established mortgage loan servicing
institution acceptable to the Certificate Insurer that has a net worth of not
less than $15,000,000 as the successor to the Servicer hereunder in the
assumption of all or any part of the responsibilities, duties or liabilities of
the Servicer hereunder.

          (c) In the event the Trustee is the successor servicer, it shall be
entitled to the Servicing Compensation and other funds pursuant to Section 5.13
hereof as the Servicer if the Servicer had continued to act as servicer
hereunder. In the event the Trustee is unable or unwilling to act as successor
servicer, the Trustee shall solicit, by public announcement, bids from housing
and home finance institutions, banks and mortgage servicing institutions meeting
the qualifications set forth above. Such public announcement shall specify that
the successor servicer shall be entitled to the full amount of the aggregate
Servicing Fees hereunder as servicing compensation, together with the other
Servicing Compensation. Within thirty days after any such public announcement,
the Trustee shall negotiate and effect the sale, transfer and assignment of the
servicing rights and responsibilities hereunder to the qualifying party
submitting the highest qualifying bid. The Trustee shall deduct from any sum
received by the Trustee from the successor to the Servicer in respect of such
sale, transfer and assignment all costs and expenses of any public announcement
and of any sale, transfer and assignment of the servicing rights and
responsibilities hereunder and the amount of any unreimbursed Servicing Advances
and Delinquency Interest Advances owed to the Trustee. After such deductions,
the remainder of such sum shall be paid by the Trustee to the Servicer at the
time of such sale, transfer and assignment to the Servicer's successor.

          (d) The Trustee and such successor shall take such action, consistent
with this Agreement, as shall be necessary to effectuate any such succession.
The Servicer agrees to cooperate with the Trustee and any successor servicer in
effecting the termination of the Servicer's servicing responsibilities and
rights hereunder and shall promptly provide the Trustee or such successor
servicer, as applicable, at the Servicer's cost and expense, all documents and
records reasonably requested by it to enable it to assume the Servicer's
functions hereunder and shall promptly also transfer to the Trustee or such
successor servicer, as applicable, all amounts that then have been or should
have been deposited in the Collection Account by the Servicer or that are
thereafter received with respect to the Mortgage Loans. Any collections received
by the Servicer after such removal or resignation shall be held by the Servicer
in trust for the benefit of the Certificateholders and the Certificate Insurer
and shall be endorsed by it to the Trustee and remitted directly to the Trustee
or, at the direction of the Trustee, to the successor servicer. Neither the
Trustee nor any other successor servicer shall be held liable by reason of any
failure to make, or any delay in making, any distribution hereunder or any
portion thereof caused by (i) the failure of the Servicer to deliver, or any
delay in delivering, cash, documents or records to it, or (ii) restrictions
imposed by any regulatory authority having jurisdiction over the Servicer
hereunder. No appointment of a successor to the Servicer hereunder shall be
effective until the Trustee and the Certificate Insurer shall have consented
thereto, and written notice of such proposed appointment shall have been
provided by the Trustee to the Certificate Insurer and to each
Certificateholder. The Trustee shall not resign as servicer until a successor
servicer reasonably acceptable to the Certificate Insurer has been appointed and
has assumed the Servicer's responsibilities and obligations hereunder.

          (e) Pending appointment of a successor to the Servicer hereunder, the
Trustee shall act in such capacity as herein above provided. In connection with
such appointment and assumption, the Trustee may make such arrangements for the
compensation of such successor out of payments on Mortgage Loans as it and such
successor shall agree; PROVIDED, HOWEVER, that no such compensation shall be in
excess of that permitted the Servicer pursuant to Section 5.13, together with
other Servicing Compensation. The Servicer, the Trustee and such successor shall
take such action, consistent with this Agreement, as shall be necessary to
effectuate any such succession.

          Section 7.3 WAIVER OF DEFAULTS. The Certificate Insurer or the
Majority Certificateholders may, on behalf of all Certificateholders, and
subject to the consent of the Certificate Insurer, waive any events permitting
removal of the Servicer as servicer pursuant to this Article VII; PROVIDED,
HOWEVER, that the Majority Certificateholders may not waive a default in making
a required distribution on a Certificate without the consent of the holder of
such Certificate. Upon any waiver of a past default, such default shall cease to
exist, and any Event of Default 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 each of the Rating Agencies.

          Section 7.4 MORTGAGE LOANS, TRUST FUND AND ACCOUNTS HELD FOR BENEFIT
OF THE CERTIFICATE INSURER. (a) The Trustee shall hold the Trust Fund and the
Mortgage Files for the benefit of the Certificateholders and the Certificate
Insurer and all references in this Agreement and in the Certificates to the
benefit of Holders of the Certificates shall be deemed to include the
Certificate Insurer. The Trustee shall cooperate in all reasonable respects with
any reasonable request by the Certificate Insurer for action to preserve or
enforce the Certificate Insurer's rights or interests under this Agreement and
the Certificates unless, as stated in an Opinion of Counsel addressed to the
Trustee and the Certificate Insurer, such action is adverse to the interests of
the Certificateholders or diminishes the rights of the Certificateholders or
imposes additional burdens or restrictions on the Certificateholders.

          (b) The Servicer hereby acknowledges and agrees that it shall service
the Mortgage Loans for the benefit of the Certificateholders and for the benefit
of the Certificate Insurer, and all references in this Agreement to the benefit
of or actions on behalf of the Certificateholders shall be deemed to include the
Certificate Insurer.

          (b) In addition, subject to Section 8.2, the holder of a 50.01%
Percentage Interest or greater of the Class RL Certificates or the Servicer (or
the Certificate Insurer, if the Servicer fails to exercise such option) may, at
its option and at its sole cost and expense, terminate this Agreement on any
date on which the related Pool Principal Balance is less than 10% of the Maximum
Collateral Amount (if the holders of the Class RL Certificates exercise this
option) or is less than 5% of the Maximum Collateral Amount (if the Servicer or
the Certificate Insurer exercises this option), by purchasing, on the next
succeeding Distribution Date, all of the outstanding Mortgage Loans and REO
Properties at a price equal to the sum of (i) the greater of (x) 100% of the
aggregate Principal Balance of each Outstanding Mortgage Loan and each REO
Property and (y) the fair market value (disregarding accrued interest) of the
Mortgage Loans and REO Properties, determined as the average of three written
bids (copies of which are to be delivered to the Trustee and the Certificate
Insurer by the Servicer and the reasonable cost of which may be deducted from
the final purchase price PROVIDED THAT such deduction will not cause a draw on
the Certificate Insurance Policy) made by nationally recognized dealers
acceptable to the Certificate Insurer and based on a valuation process which
would be used to value comparable mortgage loans and REO property, (ii) the
greater of (x) the aggregate amount of accrued and unpaid interest on the
Mortgage Loans through the related Collection Period and (y) 30 days' accrued
interest thereon at a rate equal to the Mortgage Interest Rate, (iii) and in the
event the Holders of the Residual Certificates or the Certificate Insurer
exercises such option, plus any unpaid and accrued Servicing Fees or in the
event the Servicer exercises such option, net of the Servicing Fee, and (iv) any
unreimbursed amounts due to the Servicer hereunder and the Certificate Insurer
hereunder or under the Certificate Insurance Agreement (the "Termination
Price"). Any such purchase shall be accomplished by deposit into the Certificate
Account of the Termination Price. No such termination is permitted without the
prior written consent of the Certificate Insurer (i) if it would result in a
draw on the Certificate Insurance Policy and (ii) unless the Servicer shall have
delivered to the Certificate Insurer an Opinion of Counsel reasonably
satisfactory to the Certificate Insurer stating that no amounts paid hereunder
are subject to recapture as preferential transfers under the United States
Bankruptcy Code, 11 U.S.C. ss. ss. 101 ET SEQ., as amended.

          (c) If on any Distribution Date, the Servicer determines that there
are no Outstanding Mortgage Loans and no other funds or assets in the Trust Fund
other than funds in the Certificate Account, the Servicer shall send a final
distribution notice promptly to the Certificate Insurer and to each such
Certificateholder in accordance with paragraph (d) below.

          (d) Notice of any termination, specifying the Distribution Date upon
which the Trust Fund will terminate and the Certificateholders shall surrender
their Certificates to the Trustee for payment of the final distribution and
cancellation, shall be given promptly by the Servicer by letter to the
Certificate Insurer and to each of the Certificateholders identified to the
Servicer by the Trustee as the Certificateholders of record as of the most
recent Record Date, and shall be mailed during the month of such final
distribution before the Servicer Distribution Date in such month, specifying (i)
the Distribution Date upon which final payment of the Certificates will be made
upon presentation and surrender of Certificates at the office of the Trustee
therein designated, (ii) the amount of any such final payment and (iii) that the
Record Date otherwise applicable to such Distribution Date is not applicable,
payments being made only upon presentation and surrender of the Certificates at
the office of the Trustee therein specified. The Servicer shall give such notice
to the Trustee therein specified. The Servicer shall give such notice to the
Trustee at the time such notice is given to Certificateholders. The rights of
the Certificate Insurer hereunder shall terminate (i) upon the deposit by the
Servicer with the Trustee of a sum sufficient to purchase all of the Mortgage
Loans and REO Properties as set forth above and when the Class A Principal
Balance has been reduced to zero and (ii) when the Certificate Insurer has
received all amounts owing to it hereunder and under the Certificate Insurance
Agreement.

          (e) In the event that all of the Certificateholders shall not
surrender their Certificates for cancellation within six months after the time
specified in the above-mentioned written notice, the Trustee 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 six months after the second notice, all of the Certificates
shall not have been surrendered for cancellation, the Trustee may take
appropriate steps, or may appoint an agent to take appropriate steps, to contact
the remaining Certificateholders concerning surrender of their Certificates and
the cost thereof shall be paid out of the funds and other assets which remain
subject hereto. If within nine months after the second notice all the
Certificates shall not have been surrendered for cancellation, the Residual
Certificateholders 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 only to the Residual Certificateholders for payment. Such funds shall
remain uninvested.

          Section 8.2 ADDITIONAL TERMINATION REQUIREMENTS. (a) In the event that
the Class RL Certificateholders, the Servicer or the Certificate Insurer (any of
which, an "Exercising Party") exercises its purchase option as provided in
Section 8.1, the Trust Fund shall be terminated in accordance with the following
additional requirements, unless the Trustee and the Certificate Insurer have
been furnished with an Opinion of Counsel to the effect that the failure of the
Trust Fund to comply with the requirements of this Section 8.2 will not (i)
result in the imposition of taxes on "prohibited transactions" of the Upper-Tier
REMIC or Lower-Tier REMIC as defined in Section 860F of the Code or (ii) cause
the Upper-Tier REMIC or Lower- Tier REMIC to fail to qualify as a REMIC at any
time that any Class A Certificates are outstanding:

                           (i) within 90 days prior to the final Distribution
                  Date the Trustee shall adopt and the Trustee shall sign, a
                  plan of complete liquidation of each of the Upper-Tier REMIC
                  or Lower-Tier REMIC meeting the requirements of a "Qualified
                  Liquidation" under Section 860F of the Code and any
                  regulations thereunder;

                           (ii) at or after the time of adoption of such a plan
                  of complete liquidation, which plan shall include a
                  description of the method for such liquidation and the price
                  to be conveyed for all of the assets of the Trust Fund at the
                  time of such liquidation, and at or prior to the final
                  Distribution Date, the Trustee shall sell all of the assets of
                  the Trust Fund to the Exercising Party for cash; and

                           (iii) at the time of the making of the final payment
                  on the Certificates, the Trustee shall distribute or credit,
                  or cause to be distributed or credited (A) to the Class A
                  Certificateholders, the Class A Principal Balance, plus one
                  month's interest thereon at the Class A Pass-Through Rate, (B)
                  to the Certificate Insurer, all amounts due to it hereunder
                  and under the Certificate Insurance Agreement, (C) to the
                  Class B Certificateholders, any Class B Principal Balance then
                  remaining unpaid, and (D) to the Class RL and Class RU
                  Certificateholders, respectively, all of the Lower-Tier
                  REMIC's and the Upper-Tier REMIC's respective cash on hand
                  after such payment to the Class A and Class B
                  Certificateholders and the Certificate Insurer, and the Trust
                  Fund shall terminate at such time.

          (b) By their acceptance of the 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 or upon the
written request of the Certificate Insurer 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.

          Section 8.3 ACCOUNTING UPON TERMINATION OF Servicer. Upon termination
of the Servicer, the Servicer shall, at its expense:

          (a) deliver to its successor or, if none shall yet have been
appointed, to the Trustee, the funds in any Account;

          (b) deliver to its successor or, if none shall yet have been
appointed, to the Trustee all Mortgage Files and related documents and
statements held by it hereunder and a Mortgage Loan portfolio computer tape;

          (c) deliver to its successor or, if none shall yet have been
appointed, to the Trustee, the Certificate Insurer and, upon request, to the
Certificateholders a full accounting of all funds, including a statement showing

it for the payments or charges with respect to the Mortgage Loans; and

          (d) execute and deliver such instruments and perform all acts
reasonably requested in order to effect the orderly and efficient transfer of

definitively vest in such successor all rights, powers, duties,
responsibilities, obligations and liabilities of the "Servicer" under this
Agreement.

                                   ARTICLE IX

                                   THE TRUSTEE

          Section 9.1 DUTIES OF TRUSTEE. (a) The Trustee, prior to the
occurrence of an Event of Default and after the curing of all Events of Default
which may have occurred, undertakes to perform such duties and only such duties
as are specifically set forth in this Agreement. If an Event of Default has
occurred and has not been cured or waived, the Trustee shall exercise such of
the rights and power vested in it by this Agreement, and use the same degree of
care and skill in its exercise as a prudent person would exercise or use under
the circumstances in the conduct of such person's own affairs.

          (b) The Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to the Trustee which are specifically required to be furnished pursuant to any
provision of this Agreement, shall examine them to determine whether they
conform on their face to the requirements of this Agreement; PROVIDED, HOWEVER,
that the Trustee shall not be responsible for the accuracy or content of any
resolution, certificate, statement, opinion, report, document, order or other
instrument furnished by the Servicer or the Seller hereunder. If any such
instrument is found not to conform on its face to the requirements of this
Agreement, the Trustee shall take 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, at the expense of the Servicer, notify the
Certificate Insurer and request written instructions as to the action it deems
appropriate to have the instrument corrected, and if the instrument is not so
corrected, the Trustee will provide notice thereof to the Certificate Insurer
who shall then direct the Trustee as to the action, if any, to be taken.

          (c) 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 willful misconduct; PROVIDED, HOWEVER, that:

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

                           (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
                  Certificate Insurer or with the consent of the Certificate
                  Insurer, the Class A Certificateholders holding Class A
                  Certificates evidencing Percentage Interests of at least 25%,
                  relating to the time, method and place of conducting any
                  proceeding for any remedy available to the Trustee, or
                  exercising any trust or power conferred upon the Trustee,
                  under this Agreement;

                           (iv) The Trustee shall not be required to take notice
                  or be deemed to have notice or knowledge of any default or
                  Event of Default (except an Event of Default with respect to
                  the nonpayment of any amount described in Section 7.1(a)),
                  unless a Responsible Officer of the Trustee shall have
                  received written notice thereof. In the absence of receipt of
                  such notice, the Trustee may conclusively assume that there is
                  no default or Event of Default (except a failure to make a
                  Delinquency Interest Advance);

                           (v) The Trustee shall not be required to expend or
                  risk its own funds or otherwise incur financial liability for
                  the performance of any of its duties hereunder or the exercise
                  of any of its rights or powers if there is reasonable ground
                  for believing that the repayment of such funds or adequate
                  indemnity against such risk or liability is not reasonably 
                  assured to it and none of the provisions contained in this 
                  Agreement shall in any event require the Trustee to perform, 
                  or be responsible for the manner of performance of, any of the
                  obligations of the Servicer under this Agreement except during
                  such time, if any, as the Trustee shall be the successor to,
                  and be vested with the rights, duties powers and privileges
                  of, the Servicer in accordance with the terms of this
                  Agreement; and

                           (vi) Subject to the other provisions of this
                  Agreement and without limiting the generality of this Section,
                  the Trustee shall have no duty (A) to see to any recording,
                  filing, or depositing of this Agreement or any agreement
                  referred to herein or any financing statement or continuation
                  statement evidencing a security interest, or to see to the
                  maintenance of any such recording or filing or depositing or
                  to any rerecording, refiling or redepositing of any thereof,
                  (B) to see to any insurance, (C) to see to the payment or
                  discharge of any tax, assessment, or other governmental charge
                  or any lien or encumbrance of any kind owing with respect to,
                  assessed or levied against, any part of the Trust, the Trust
                  Fund, the Certificateholders or the Mortgage Loans, (D) to
                  confirm or verify the contents of any reports or certificates
                  of the Servicer delivered to the Trustee pursuant to this
                  Agreement believed by the Trustee to be genuine and to have
                  been signed or presented by the proper party or parties.

          Section 9.2 CERTAIN MATTERS AFFECTING THE TRUSTEE. (a) Except as
otherwise provided in Section 9.1:

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

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

                           (iii) the Trustee shall be under no obligation to
                  exercise any of the trusts or powers vested in it by this
                  Agreement or to institute, conduct or defend by litigation
                  hereunder or in relation hereto at the request, or direction
                  of the Certificate Insurer or any of the Certificateholders,
                  pursuant to the provisions of this Agreement, unless such
                  Certificateholders or the Certificate Insurer, as
                   applicable, shall have offered to the Trustee reasonable
                  security or indemnity against the costs, expenses and
                  liabilities which may be incurred therein or thereby; nothing
                  contained herein shall, however, relieve the Trustee of the
                  obligation, upon the occurrence of an Event of Default (which
                  has not been cured), to exercise such of the rights and powers
                  vested in it by this Agreement, and to use the same degree of
                  care and skill in its exercise as a prudent person would
                  exercise or use under the circumstances in the conduct of such
                  person's own affairs;

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

                           (v) prior to the occurrence of an Event of Default
                  hereunder and after the curing of all Events of Default which
                  may have occurred, the Trustee shall not be bound to make any
                  investigation into the facts or matters stated in any
                  resolution, certificate, statement, instrument, opinion,
                  report, notice, request, consent, order, approval, bond or
                  other paper or document, unless requested in writing to do so
                  by the Certificate Insurer or Holders of Class A Certificates
                  evidencing Percentage Interests aggregating not less than 25%;
                  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 expense or liability as a
                  condition to taking any such action;

                           (vi) 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;

                           (vii) the Trustee shall not be required to
                  give any bond or surety in respect of the execution
                  of the Trust Fund created hereby or the powers granted
                   hereunder; and

                           (viii) 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.

          (b) Following the Startup Day, the Trustee shall not knowingly accept
any contribution of assets to the Trust Fund, unless the Trustee and the
Certificate Insurer shall have received an Opinion of Counsel (at the expense of
the Servicer) to the effect that the inclusion of such assets in the Trust Fund
will not cause the Upper-Tier REMIC or Lower-Tier REMIC to fail to qualify as a
REMIC at any time that any Certificates are outstanding or subject the
Upper-Tier REMIC or Lower-Tier REMIC to any tax under the REMIC Provisions or
other applicable provisions of federal, state and local law or ordinances. The
Trustee agrees to indemnify the Trust Fund, the Certificate Insurer and the
Servicer for any taxes and costs, including any attorney's fees, imposed or
incurred by the Trust Fund, the Certificate Insurer or the Servicer as a result
of the breach of the Trustee's covenants set forth within this subsection (b).

          Section 9.3 NOT LIABLE FOR CERTIFICATES OR MORTGAGE LOANS. The
recitals contained herein (other than the certificate of authentication on the
Certificates) shall be taken as the statements of the Seller and the Trustee
assumes no responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Agreement or of any
Mortgage Loan or related document. The Trustee shall not be accountable for the
use or application of any funds paid to the Servicer in respect of the Mortgage
Loans or deposited in or withdrawn from the Collection Account by the Servicer.
The Trustee shall not be responsible for the legality or validity of the
Agreement or the validity, priority, perfection or sufficiency of the security
for the Certificates issued or intended to be issued hereunder.

          Section 9.4 TRUSTEE MAY OWN CERTIFICATES. The Trustee in its
individual or any other capacity may become the owner or pledgor of Certificates
with the same rights it would have if it were not Trustee, and may otherwise
deal with the parties hereto.

          Section 9.5 PAYMENT OF TRUSTEE FEES. The Trustee shall withdraw from
the Certificate Account on each Distribution Date and pay to itself the Trustee
Fee. Except as otherwise provided in this Agreement, the Trustee and any
director, officer, employee or agent of the Trustee shall be indemnified by the
Trust Fund and held harmless against any loss, liability or "unanticipated
out-of-pocket" expense incurred or paid to third parties (which expenses shall
not include salaries paid to employees, or allocable overhead, of the Trustee)
in connection with the acceptance or administration of its trusts hereunder, the
Certificate Insurance Agreement or the Certificates, other than any loss,
liability or expense incurred by reason of willful misfeasance, bad faith or
negligence in the performance of duties hereunder or by reason of reckless
disregard of obligations and duties hereunder. The provisions of this Section
9.5 shall survive the termination of this Agreement and the removal or
resignation of the Trustee.

          The Servicer covenants and agrees to indemnify the Trustee and the
Certificate Insurer and any director, officer, employee or agent of either
against any losses, liabilities, damages, claims or expenses (including
reasonable legal fees and such related expenses) that may be sustained by the
Trustee in connection with this Agreement and the Certificate Insurance
Agreement related to the willful misfeasance, bad faith or negligence in the
performance of the Servicer's duties hereunder.

          Section 9.6 ELIGIBILITY REQUIREMENTS FOR TRUSTEE. The Trustee
hereunder shall at all times be (a) a banking association organized and doing
business under the laws of any state or the United States of America subject to
supervision or examination by federal or state authority, (b) authorized under
such laws to exercise corporate trust powers, including taking title to the
Trust Fund assets on behalf of the Certificateholders (c) having a combined
capital and surplus of at least $50,000,000, (d) whose long-term deposits, if
any, shall be rated at least BBB by S&P and Baa3 by Moody's (except as provided
herein) or such lower long-term deposit rating as may be approved in writing by
the Certificate Insurer, (e) whose short-term deposits rating is rated A-1 + by
S&P and P-1 by Moody's, and (f) reasonably acceptable to the Certificate Insurer
as evidenced in writing. If such banking association 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 shall be deemed to be its combined capital and surplus as set forth in
its most recent report of condition so published. In case at any time the
Trustee shall cease to be eligible in accordance with the provisions of this
Section, the Trustee shall resign immediately in the manner and with the effect
specified in Section 9.7.

          Section 9.7 RESIGNATION AND REMOVAL OF THE Trustee. (a) The Trustee
may at any time resign and be discharged from the trusts hereby created by
giving at least 30 days' prior written notice thereof to the Servicer, the
Certificate Insurer and to all Certificateholders. Upon receiving such notice of
resignation, the Certificate Insurer may appoint a successor trustee and if the
Certificate Insurer fails to appoint a successor trustee, the Servicer shall
promptly appoint a successor trustee acceptable to the Certificate Insurer
(which acceptance shall not be unreasonably withheld) by written instrument, in
duplicate, which instrument shall be delivered to the resigning Trustee and to
the successor trustee. A copy of such instrument shall be delivered to the
Depositor, the Certificateholders, the Certificate Insurer and the Seller by the
Servicer. Unless a successor trustee shall have been so appointed and have
accepted appointment within 30 days after the giving of such notice of
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor trustee.

          (b) If at any time the Trustee shall cease to be eligible in
accordance with the provisions of Section 9.6 and shall fail to resign after
written request therefor by the Servicer or the Certificate Insurer, or if at
any time the Trustee shall become incapable of acting, or shall be adjudged
bankrupt or insolvent, or a receiver of the Trustee or of its 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 Certificate Insurer may appoint a successor trustee and if
the Certificate Insurer fails to appoint a successor trustee, the Servicer or
the Certificate Insurer may remove the Trustee and the Servicer shall, within 30
days after such removal, appoint, subject to the approval of the Certificate
Insurer, which approval shall not be unreasonably delayed, a successor trustee
by written instrument, in duplicate, which instrument shall be delivered to the
Trustee so removed and to the successor trustee. A copy of such instrument shall
be delivered to the Depositor, the Certificateholders, the Certificate Insurer
and the Seller by the Servicer.

          (c) If the Trustee fails to perform in accordance with the terms of
this Agreement, the Majority Certificateholders (with the consent of the
Certificate Insurer, which consent shall not be unreasonably withheld) or the
Certificate Insurer may remove the Trustee and appoint a successor trustee
acceptable to the Certificate Insurer by written instrument or instruments, in
triplicate, signed by such Holders or their attorneys-in-fact duly authorized,
one complete set of which instruments shall be delivered to the Servicer and the
Certificate Insurer, one complete set to the Trustee so removed and one complete
set to the successor Trustee so appointed.

          (d) Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this Section shall become
effective upon acceptance of appointment by the successor trustee as provided in
Section 9.8.

          (e) Upon any termination of, or appointment of any successor to the
Trustee hereunder, the Trustee shall promptly transfer all of the Residual
Interest (as defined under the Code) of the Trust Fund to the successor Trustee.

          Section 9.8 SUCCESSOR TRUSTEE. Any successor trustee appointed as
provided in Section 9.7 shall execute, acknowledge and deliver to the Depositor,
the Certificate Insurer, the Seller, the Servicer and to its predecessor trustee
an instrument accepting such appointment hereunder, and thereupon the
resignation or removal of the predecessor trustee shall become effective and
such successor trustee, without any further act, deed or conveyance, shall
become fully vested with all the rights, powers, duties and obligations of its
predecessor hereunder, with the like effect as if originally named as trustee
herein. The predecessor trustee shall deliver to the successor trustee all
Mortgage Files and related documents and statements held by it hereunder, and
the Servicer and the predecessor trustee shall execute and deliver such
instruments and do such other things as may reasonably be required for more
fully and certainly vesting and confirming in the successor trustee all such
rights, powers, duties and obligations. No successor trustee shall accept
appointment as provided in this Section unless at the time of such acceptance
such successor trustee shall be eligible under the provisions of Section 9.6.
Upon acceptance of appointment by a successor trustee as provided in this
Section, the Servicer shall mail notice of the succession of such trustee
hereunder to all Holders of Certificates at their addresses as shown in the
Certificate Register (such Certificate Register shall be provided to the
Servicer by the Successor Trustee) and to each of the Rating Agencies. If the
Servicer fails to mail such notice within 10 days after acceptance of
appointment by the successor trustee, the successor trustee shall cause such
notice to be mailed at the expense of the Servicer.

          Section 9.9 MERGER OR CONSOLIDATION OF TRUSTEE. Any Person into which
the Trustee may be merged or converted or with which it may be consolidated or
any corporation or national banking association resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation or national banking association succeeding to the business of the
trustee, shall be the successor of the Trustee hereunder, provided such
corporation or national banking association shall be eligible under the
provisions of Section 9.6, 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 9.10 APPOINTMENT OF CO-TRUSTEE OR SEPARATE TRUSTEE. (a)
Notwith standing any other provisions hereof, at any time, for the purpose of
meeting any legal requirements of any jurisdiction in which any part of the
Trust Fund or property securing the same may at the time be located, the
Servicer and the Trustee acting jointly shall have the power and shall execute
and deliver all instruments to appoint one or more Persons approved by the
Trustee 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 Fund, and
to vest in such Person or Persons, in such capacity, such title to the Trust
Fund, or any part thereof, and, subject to the other provisions of this Section
9.10, such powers, duties, obligations, rights and trusts as the Servicer and
the Trustee may consider necessary or desirable. If the Servicer shall not have
joined in such appointment within 15 days after the receipt by it of a request
so to do, or in case an Event of Default shall have occurred and be continuing,
the Trustee alone shall have the power to make such appointment. No co-trustee
or separate trustee hereunder shall be required to meet the terms of eligibility
as a successor trustee under Section 9.6 hereunder and no notice to Holders of
Certificates of the appointment of co-trustee(s) or separate trustee(s) shall be
required under Section 9.8 hereof.

          (b) In the case of any appointment of a co-trustee or separate trustee
pursuant to this Section 9.10, all rights, powers, duties and obligations
conferred or imposed upon the Trustee shall be conferred or imposed upon and
exercised or performed by the Trustee and such separate trustee or co-trustee
jointly, except to the extent that under any law of any jurisdiction in which
any particular act or acts are to be performed (whether as Trustee hereunder or
as successor to the 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 Fund or any
portion thereof in any such jurisdiction) shall be exercised and performed by
such separate trustee or co-trustee at the direction of the Trustee.

          (c) 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 IX. Each separate trustee and co-trustee, upon its acceptance of
the trusts conferred, shall be vested with the estates or property specified in
its instrument of appointment, either jointly with the Trustee or separately, as
may be provided therein, subject to all the provisions of this Agreement,
specifically including every provision of this Agreement relating to the conduct
of, affecting the liability of, or affording protection to, the Trustee. Every
such instrument shall be filed with the Trustee.

          (d) 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. The Trustee shall not be
responsible for any action or inaction of any such separate trustee or
co-trustee, PROVIDED THAT the Trustee appointed such separate trustee or
co-trustee with due care. 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 9.11 RETIREMENT OF CERTIFICATES. The Trustee shall, upon the
retirement of the Certificates pursuant hereto or otherwise, furnish to the
Certificate Insurer a notice of such retirement, and, upon retirement of the
Class A Certificates shall surrender the Certificate Insurance Policy to the
Certificate Insurer for cancellation.

                       REMIC ADMINISTRATION AND PROVISIONS

          Section 10.1 REMIC ADMINISTRATION. (a) The Trust Fund shall elect that
the Upper-Tier REMIC and the Lower-Tier REMIC shall be treated as REMICs under
Section 860D of the Code. Such elections will be made on Form 1066 or other
appropriate federal tax or information returns and any appropriate state returns
for the taxable year ending on the last day of the calendar year in which the
Certificates are issued. Any inconsistencies or ambiguities in this Agreement or
in the administration of the Trust Fund shall be resolved in a manner that
preserves the validity of such REMIC elections.

          (b) The Class A Certificates and the Class B Certificates are hereby
designated as "regular interests" with respect to the Upper-Tier REMIC and the
Class RU Certificates are hereby designated as the single class of "residual
interest" with respect to the Upper-Tier REMIC. The REMIC Administrator shall
not permit the creation of any "interests" in the Trust Fund (within the meaning
of Section 860G of the Code) other than the Upper-Tier and Lower-Tier REMIC
regular interests and the interests represented by the Residual Certificates.

          (c) The Lower-Tier REMIC will be evidenced by (x) the Class LT-A,
Class LT-1, Class LT-2, Class LT-3, Class LT-4, Class LT-5, Class LT-6 and Class
LT-M Certificates (the "Lower-Tier Regular Interests"), which will be
uncertificated and non-transferable and are hereby designated as the "regular
interests" in the Lower-Tier REMIC and (y) the Class RL Certificates, which are
hereby designated as the single "residual interest" in the Lower-Tier REMIC (the
Lower-Tier Regular Interests, together with the Class RL Certificates, the
"Lower- Tier Interests"). The Lower-Tier Regular Interests shall be recorded on
the records of the Lower- Tier REMIC as being issued to and held by the REMIC
Administrator on behalf of the Upper- Tier REMIC.

          Any (i) Overcollateralization Deficit (including the portion of a
Class A Carryforward Amount which relates to a shortfall in a distribution of an
Overcollateralization Deficit) and (ii) any Overcollateralization Increase
Amount (without duplication of amounts described in (i)) (together, the "Turbo
Amount") that is payable from interest on the Mortgage Loans will not be paid to
the Lower-Tier Regular Interests, but a portion of the interest payable with
respect to the Class LT-M Certificate which equals 1% of the Turbo Amount will
be payable as a reduction of the principal balances of the Class LT-1, Class
LT-2, Class LT-3, Class LT-4, Class LT-5 and Class LT-6 Certificates in the same
manner in which the Turbo Amount is allocated among the Class A-1, Class A-2,
Class A-3, Class A-4, Class A-5 and Class A-6 Certificates, respectively (and
will be accrued and added to principal on the Class LT-M Certificate). Principal
payments on the Mortgage Loans shall be allocated 98% to the Class LT- A
Certificate, 1% to the Class LT-M Certificate, and 1% to the Class LT-1, Class
LT-2, Class LT-3, Class LT-4, Class LT-5 and Class LT-6 Certificates. The
aggregate amount of principal allocated to the Class LT-1, Class LT-2, Class
LT-3, Class LT-4, Class LT-5 and Class LT-6 Certificates shall be apportioned
among such Classes in the same manner in which principal is payable with respect
to the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5 and Class A-6
Certificates, respectively. Notwithstanding the above, 98% and 2% of any
principal payments on the Mortgage Loans that are attributable to an
Overcollateralization Reduction Amount shall be allocated to the Class LT-A and
Class LT-M Certificates, respectively. Similarly, 98% and 2% of any realized
losses with respect to principal on the Mortgages Loans shall be allocated to
the Class LT-A and Class LT-M Certificates, respectively, except that to the
extent such realized losses create an Overcollateralization Deficit that is not
paid from interest on the Mortgage Loans (but is paid by the Certificate
Insurer), such losses shall be allocated 98% to the Class LT-A Certificate, 1%
to the Class LT-M Certificate and 1% to the Class LT-1, Class LT-2, Class LT-3,
Class LT-4, Class LT-5 and Class LT-6 Certificates, apportioned among such Class
LT-1, Class LT-2, Class LT-3, Class LT-4, Class LT-5 and Class LT-6 Certificates
in the same manner in which the Overcollateralization Deficit is payable with
respect to the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5 and Class
A-6 Certificates, respectively. The Lower-Tier Interests will have the following
designations and pass-through rates, and distributions of principal and interest
thereon shall be allocated to the Class A Certificates in the following manner:

- -----------------
(1)      Except as otherwise indicated, the amount of principal and interest
         allocable from a Lower-Tier Interest to the Class A Certificates on any
         Distribution Date shall be 100%.

(2)       The pass-through rate on these Lower-Tier Regular Interests shall at 
          any time of determination equal the weighted average of the Net 
          Mortgage Interest Rates for each of the Mortgage Loans.  Any 
          shortfalls in interest on the Lower-Tier Regular Interests that result
          from Principal Prepayments on any Mortgage Loans during the
          related Collection  Period after accounting for any
          Compensating Interest paid under Section 6.9 shall
          proportionately reduce the interest accrued on the Lower-Tier Regular 
          Interests.

 (3)     Principal will be allocated to and apportioned among the
         Class A-1, Class A-2, Class A- 3, Class A-4, Class A-5, and
         Class A-6 Certificates in the same proportion as principal
         is payable with respect to such Certificates, except that
         a portion of such principal in an  amount equal to the
         Overcollateralization Reduction Amount shall first be
         allocated to the Class B Certificates, and all principal
         will be allocated to the Class B Certificates after the
         Class A Principal Balance has been reduced to zero.

(4)      Except as provided in footnotes, Interest will be allocated among the
         Class A-1, Class A- 2, Class A-3, Class A-4, Class A-5, and Class A-6
         Certificates in the same proportion as interest is payable on such
         Certificates.

(5)      Any interest with respect to this Lower-Tier Interest in
         excess of the product of (i) two  times the weighted
         average coupon of the Class LT-1, Class LT-2, Class LT-3,
         Class LT- 4, Class LT-5, Class LT-6 and Class LT-M
         Certificates, where each of such Classes,  other than the
         Class LT-M Certificate, is first subject to a cap and floor
         equal to the Class  A-1, Class A-2, Class A-3, Class A-4,
         Class A-5 and Class A-6 Pass-Through Rate ,  respectively,
         and the Class LT-M Certificate is subject to a cap equal to
         0%, and (ii) the  principal balance of this Lower-Tier
         Interest, shall not be allocated to the Class A Certificates but will 
         be allocated to the Class B Certificates as a separate component.

(6)      On each Distribution Date, available funds, if any, remaining in the
         Lower-Tier REMIC after payments of interest and principal, as
         designated above, will be distributed to the Class RL Certificate.

(7)      The principal balances of the Class LT-A and Class LT-M Certificates
         shall be increased by 98% and 2%, respectively, of the principal
         balance of each Subsequent Mortgage Loan as of the related Subsequent
         Cut-Off Date.
</TABLE>

          (d) The Closing Date is hereby designated as the Startup Day of the
Upper- Tier REMIC and Lower-Tier REMIC within the meaning of Section 860G(a)(9)
of the Code.

          (e) The REMIC Administrator shall pay out of its own funds, without
any right of reimbursement, any and all expenses relating to any tax audit of
the Trust Fund (including, but not limited to, any professional fees or any
administrative or judicial proceedings with respect thereto that involved the
Internal Revenue Service or state tax authorities), other than the expense of
obtaining any tax related Opinion of Counsel not obtained in connection with
such an audit and other than taxes, in either case except as specified herein;
PROVIDED, HOWEVER, that if such audit resulted from the negligence of the
Servicer or the Depositor, then the Servicer or the Depositor, as the case may
be, shall pay such expenses. The REMIC Administrator, as agent for the tax
matters person, shall (i) act on behalf of the Trust Fund in relation to any tax
matter or controversy involving the Trust Fund and (ii) represent the Trust Fund
in any administrative or judicial proceeding relating to an examination or audit
by any governmental taxing authority with respect thereto. The Holders of the
largest Percentage Interest in the Class RU and Class RL Certificates of the
Upper-Tier REMIC and Lower-Tier REMIC, respectively, from time to time are
hereby designated as Tax Matters Person with respect to the Upper-Tier REMIC and
Lower-Tier REMIC, respectively, and hereby irrevocably appoint and authorize the
Trustee to act as their agent to perform the duties of the Tax Matters Person
with respect to each such REMIC Fund. To the extent authorized under the Code
and the regulations promulgated thereunder, each Holder of a Residual
Certificate hereby irrevocably appoints and authorizes the REMIC Administrator
to be its attorney-in-fact for purposes of signing any Tax Returns required to
be filed on behalf of the Trust Fund.

          (f) The REMIC Administrator shall prepare or cause to be prepared, and
the Trustee shall sign and file all of the Tax Returns in respect of the Trust
Fund created hereunder, other than Tax Returns required to be filed by the
Servicer pursuant to Section 5.24. The expenses of preparing and filing such
returns shall be borne by the REMIC Administrator without any right of
reimbursement therefor.

          (g) The REMIC Administrator shall perform on behalf of the Trust Fund
all reporting and other compliance duties that are the responsibility of the
Trust Fund under the Code, the REMIC Provisions or other compliance guidance
issued by the Internal Revenue Service or any state or local taxing authority.
Among its other duties, as required by the Code, the REMIC Provisions or other
such compliance guidance, the REMIC Administrator shall provide (i) to any
Transferor of a Residual Certificate such information as is necessary for the
application of any tax relating to the transfer of a Residual Certificate to any
Person who is not a Disqualified Organization, (ii) to Certificateholders such
information or reports as are required by the Code or REMIC Provisions including
reports relating to interest, original issue discount and market discount or
premium (using the Prepayment Assumption) and (iii) to the Internal Revenue
Service the name, title, address and telephone number of the person who will
serve as the representative of the Trust Fund. In addition, the Depositor shall
provide or cause to be provided to the REMIC Administrator, within ten (10) days
after the Closing Date, all information or data that the REMIC Administrator
reasonably determines to be relevant for tax purposes as to the valuations and
issue prices of the Certificates, including, without limitation, the price,
yield, prepayment assumption and projected cash flow of the Certificates.

          (h) The REMIC Administrator shall take such action and shall cause the
Trust Fund created hereunder to take such action as shall be necessary to create
or maintain the status of each of the Upper-Tier REMIC and the Lower-Tier REMIC
as a REMIC under the REMIC Provisions (and the Servicer shall assist it, to the
extent reasonably requested by the REMIC Administrator). Neither the Trustee nor
the REMIC Administrator shall take any action, cause the Trust Fund to take any
action or fail to take (or fail to cause to be taken) any action that, under the
REMIC Provisions, if taken or not taken, as the case may be, could (i) endanger
the status of the Upper-Tier REMIC or the Lower-Tier REMIC as a REMIC or (ii)
result in the imposition of a tax upon the Upper-Tier REMIC or the Lower-Tier
REMIC (including but not limited to the tax on prohibited transactions as
defined in Section 860F(a)(2) of the Code and the tax on contributions to a
REMIC set forth in Section 860G(d) of the Code or the tax on net income from
foreclosure property as defined in Section 860G(c) of the Code) (any such event,
an "Adverse REMIC Event") unless the REMIC Administrator and the Certificate
Insurer received an Opinion of Counsel (at the expense of the party seeking to
take such action but in no event shall such Opinion of Counsel be an expense of
the Trustee) to the effect that the contemplated action will not, with respect
to the Upper-Tier REMIC or the Lower-Tier REMIC, endanger such status or result
in an Adverse REMIC Event. The Servicer shall not take or fail to take any
action (whether or not authorized hereunder) as to which the REMIC Administrator
has advised it in writing that it has received an Opinion of Counsel (which such
Opinion of Counsel shall not be an expense of the REMIC Administrator) to the
effect that an Adverse REMIC Event could occur with respect to such action. In
addition, prior to taking any action with respect to the Trust Fund or its
assets, or causing the Trust Fund to take any action which is not expressly
permitted under the terms of this Agreement, the Servicer will consult with the
Certificate Insurer and with the REMIC Administrator or its designee, in
writing, with respect to whether such action could cause an Adverse REMIC Event
to occur with respect to the Upper-Tier REMIC or the Lower-Tier REMIC, and the
Servicer shall not take any such action or cause the Trust Fund to take any such
action as to which the REMIC Administrator or the Certificate Insurer has
advised it in writing that an Adverse REMIC Event could occur. The REMIC
Administrator may consult with counsel to make such written advice, and the cost
of same shall be borne by the party seeking to take the action not permitted by
this Agreement (but in no event shall such cost be an expense of the REMIC
Administrator). At all times as may be required by the Code, the REMIC
Administrator and the Trustee will ensure that substantially all of the assets
of the Trust Fund will consist of "qualified mortgages" as defined in Section
860G(a)(3) of the Code and "permitted investments" as defined in Section
860G(a)(5) of the Code.

          (i) In the event that any tax is imposed on "prohibited transactions"
of the Upper-Tier REMIC or the Lower-Tier REMIC as defined in Section 860F(a)(2)
of the Code, on "net income from foreclosure property" of the Upper-Tier REMIC
or the Lower-Tier REMIC as defined in Section 860G(c) of the Code, on any
contributions to the Upper-Tier REMIC or the Lower-Tier REMIC after the Startup
Day therefor pursuant to Section 860G(d) of the Code, or any other tax is
imposed by the Code or any applicable provisions of state or local tax laws,
such tax shall be charged (i) to the REMIC Administrator pursuant to Section
10.3 hereof, if such tax arises out of or results from a breach by the REMIC
Administrator of any of its obligations under this Article X, (ii) to the
Trustee pursuant to Section 10.3 hereof, if such tax arises out of or results
from a breach by the Trustee of any of its obligations under Article IX or this

contributions of assets to the Trust Fund unless it and the Certificate Insurer
shall have received an Opinion of Counsel (which such Opinion of Counsel shall
not be an expense of the Trustee or the REMIC Administrator) to the effect that
the inclusion of such assets in the Trust Fund will not cause the Upper-Tier
REMIC or the Lower-Tier REMIC to fail to qualify as a REMIC at any time that any

REMIC to any tax under the REMIC Provisions or other applicable provisions of

                           (C) the Prepayment Assumption and any interest rate

                                   ARTICLE XI

                            MISCELLANEOUS PROVISIONS

          Section 11.1 LIMITATION ON LIABILITY OF THE DEPOSITOR AND THE
SERVICER. Neither the Depositor nor the Servicer nor any of the directors,
officers, employees or agents of the Depositor or the Servicer shall be under
any liability to the Trust, the Certificateholders or the Certificate Insurer
for any action taken, or for refraining from the taking of any action, in good
faith pursuant to this Agreement, or for errors in judgment; PROVIDED, HOWEVER,
that this provision shall not protect the Depositor or the Servicer or any such
Person against any breach of warranties or representations made herein, or
against any specific liability imposed on each such party pursuant to this
Agreement or against any liability which would otherwise be imposed by reason of
willful misfeasance, bad faith or negligence in the performance of duties or by
reason of reckless disregard of obligations or duties hereunder. The Depositor
or the Servicer and any director, officer, employee or agent of the Depositor or
the Servicer may rely in good faith on any document of any kind which, PRIMA
FACIE, is properly executed and submitted by any appropriate Person respecting
any matters arising hereunder. The Depositor, the Servicer and any director,
officer, employee or agent of the Depositor or the Servicer shall be indemnified
and held harmless by the Trust Fund against any loss, liability or expense
incurred in connection with any legal action relating to this Agreement or the
Certificates, with respect to the Servicer, other than any loss, liability or
expense related to Servicer's servicing obligations with respect to any specific
Mortgage Loan or Mortgage Loans (except as any such loss, liability or expense
shall be otherwise reimbursable pursuant to this Agreement) or related to the
Servicer's obligations under this Agreement, with respect to the Depositor, the
Seller, or Servicer, as the case may be, or any loss, liability or expense
incurred by reason of willful misfeasance, bad faith or negligence in the
performance of duties hereunder or by reason of reckless disregard of
obligations and duties hereunder. Neither the Depositor, nor the Servicer shall
be under any obligation to appear in, prosecute or defend any legal action which
is not incidental to its respective duties under this Agreement and which in its
opinion may involve it in any expense or liability; PROVIDED, HOWEVER, that the
Depositor, or the Servicer may in its sole discretion undertake any such action
which it may deem necessary or desirable with respect to this Agreement and the
rights and duties of the parties hereto and the interests of the
Certificateholders hereunder. In the event the Depositor or the Servicer take
any action as described in the preceding sentence, the legal expenses and costs
of such action, if previously approved by the Certificate Insurer, which
approval shall not be unreasonably withheld, and any liability resulting
therefrom will be expenses, costs and liabilities of the Trust Fund, and the
Servicer or the Depositor, as the case may be, will be entitled to be reimbursed
therefor out of funds in the Collection Account.

          Section 11.2 ACTS OF CERTIFICATEHOLDERS; CERTIFICATEHOLDERS' RIGHTS.
(a) Except as otherwise specifically provided herein, whenever Certificateholder
action, consent or approval is required under this Agreement, such action,
consent or approval shall be deemed to have been taken or given on behalf of,
and shall be binding upon, all Certificateholders if the Majority
Certificateholders (with the consent of the Certificate Insurer, which consent
shall not be unreasonably withheld) or the Certificate Insurer agrees to take
such action or give such consent or approval.

          (b) The death or incapacity of any Certificateholder shall not operate
to terminate this Agreement or the Trust Fund, nor entitle such
Certificateholder's legal representatives or heir to claim an accounting or to
take any action or proceeding in any court for a partition or winding up of the
Trust Fund, nor otherwise affect the rights, obligations and liabilities of the
parties hereto or any of them.

          (c) No Certificateholder shall have any right to vote (except as
expressly provided for herein) or in any manner otherwise control the operation
and management of the Trust Fund, or the obligations of the parties hereto, nor
shall anything herein set forth, or contained in the terms of 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 or thereof.

          Section 11.3 AMENDMENT. (a) This Agreement may be amended from time to
time by the Servicer, the Depositor and the Trustee by written agreement, upon
the prior written consent of the Certificate Insurer (which consent shall not be
unreasonably withheld), without notice to or consent of the Certificateholders
to cure any ambiguity, to correct or supplement any provisions herein, to comply
with any changes in the Code, or 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 such
action shall not, as evidenced by an Opinion of Counsel, at the expense of the
party requesting the change, but in no event an expense of the Trustee,
delivered to the Trustee and the Certificate Insurer, adversely affect in any
material respect the interests of any Certificateholder; PROVIDED, FURTHER, that
the amendment shall not be deemed to adversely affect in any material respect
the interests of the Certificateholders and no Opinion of Counsel to that effect
shall be required if the person requesting the amendment obtains a letter from
Moody's or S&P stating that the amendment would not result in the downgrading or
withdrawal of the respective ratings then assigned to the Class A Certificates
without regard to the Certificate Insurance Policy; and PROVIDED, FURTHER, that
no such amendment shall reduce in any manner the amount of, or delay the timing
of, payments received on Mortgage Loans which are required to be distributed on
any Certificate without the consent of the Holder of such Certificate, or change
the rights or obligations of any other party hereto without the consent of such
party. The Trustee shall give prompt written notice to Moody's and S&P of any
amendment made pursuant to this Section 11.3 and shall promptly send copies of
any such amendment to Moody's and S&P.

          (b) This Agreement may be amended from time to time by the Servicer,
the Depositor and the Trustee with the consent of the Certificate Insurer (which
consent shall not be withheld if, in the Opinion of Counsel addressed to the
Trustee and the Certificate Insurer, failure to amend would adversely affect the
interests of the Certificateholders unless such consent would adversely affect
the interests of the Certificate Insurer), 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; PROVIDED, HOWEVER, that no such amendment shall be made unless
the Trustee and the Certificate Insurer receive an Opinion of Counsel, at the
expense of the party requesting the change, that such change will not adversely
affect the status of the Upper-Tier REMIC or the Lower-Tier REMIC as a REMIC or
cause a tax to be imposed on such Upper-Tier REMIC or Lower-Tier REMIC; and
PROVIDED, FURTHER, that no such amendment shall reduce in any manner the amount
of, or delay the timing of, payments received on Mortgage Loans which are
required to be distributed on any Certificate without the consent of the Holder
of such Certificate or reduce the percentage for the Holders of which are
required to consent to any such amendment without the consent of the Holders of
100% of Certificates affected thereby.

          (c) It shall not be necessary for the consent of Holders under this
Section to approve the particular form of any proposed amendment, but it shall
be sufficient if such consent shall approve the substance thereof.

          Section 11.4 RECORDATION OF AGREEMENT. To the extent permitted by
applicable law, this Agreement, or a memorandum thereof if permitted under
applicable law, is subject to recordation in all appropriate public offices for
real property records in all of 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 Servicer at the Certificateholders' expense on direction
and at the expense of Majority Certificateholders requesting such recordation,
but only when accompanied by an Opinion of Counsel to the effect that such
recordation materially and beneficially affects the interests of the
Certificateholders or is necessary for the administration or servicing of the
Mortgage Loans.

right, title and interest in and to the applicable Mortgage Loans, together with
the Mortgage Files relating thereto and the insurance policies relating to each
such Mortgage Loan and all right, title and interest in and to all collections
thereon and the proceeds thereof on and after the Cut-Off Date. Upon payment of

Agreement, the Unaffiliated Seller shall have hereby, and shall be deemed to
have, relinquished all rights with respect to, and to have sold, transferred,
assigned, set over and conveyed such Mortgage Loans together with the Mortgage

Unaffiliated Seller as debtor, naming the Depositor as secured party and listing
the Mortgage Loans and the other property described above as collateral. The
characterization of the Unaffiliated Seller as a debtor and the Depositor as the
secured party in such financing statements is solely for protective purposes and
shall in no way be construed as being contrary to the interest of the parties
that this transaction be treated as a sale of the Unaffiliated Seller's entire
right, title and interest in the Mortgage Loans to the Depositor. In connection
with such filing, the Unaffiliated Seller agrees that it shall cause to be filed
all necessary continuation statements thereof and to take or cause to be taken
such actions and execute such documents as are necessary to perfect and protect
the Trustee's, the Certificateholders' and the Certificate Insurer's interests
in the Mortgage Loans.

          (b) Upon the sale of such Mortgage Loans, the ownership of each

in the Depositor. The contents of any Mortgage File in the possession of the
Unaffiliated Seller at any time after such sale, and any payments of principal
on the Mortgage Loans received by the Unaffiliated Seller on and after the
Cut-off Date, and interest on the Mortgage Loan due on and after the Cut-Off
Date and received by the Unaffiliated Seller, shall be held in trust by the
Unaffiliated Seller for the benefit of the Trustee (as assignee of the Depositor
pursuant to the Pooling and Servicing Agreement), and shall be promptly
delivered by the Unaffiliated Seller to or upon the order of the Trustee.

          (c) Pursuant to the Pooling and Servicing Agreement, the Depositor
shall, on the Closing Date, assign all of its right, title and interest in and
to the applicable Mortgage Loans to the Trustee for the benefit of the
Certificateholders and the Certificate Insurer.

the Closing Date or Subsequent Transfer Date, as applicable, the Unaffiliated
Seller shall deliver to the Trustee (as assignee of the Depositor pursuant to

         Mortgage shall be delivered when so returned);

                      (iii) An original assignment of the original Mortgage, in
         suitable form for recordation in the jurisdiction in which the related

         recordation of such assignment in the appropriate real estate recording
         office for such Mortgaged Property); provided, however, that
         assignments of mortgages shall not be required to be submitted for
         recording with respect to any Mortgage Loan which relates to the
         Trustee's Mortgage File if the Trustee, each of the Rating Agencies and
         the Certificate Insurer shall have received an opinion of counsel at
         the expense of the Unaffiliated Seller satisfactory to the Trustee,
         each of the Rating Agencies and the Certificate Insurer stating that,
         in such counsel's opinion, the failure to record such assignment of
         Mortgage shall not have a materially adverse effect on the security
         interest of the Trustee in the Mortgage; PROVIDED, FURTHER, that any
         assignment of Mortgage for which an opinion has been delivered shall be
         recorded by the Unaffiliated Seller upon the earlier to occur of (i)
         receipt by the Trustee of the Certificate Insurer's written direction
         to record such Mortgage, (ii) the occurrence of any Event of Default,
         as such term is defined in the Pooling and Servicing Agreement, or
         (iii) a bankruptcy or insolvency proceeding involving the Mortgagor is
         initiated or foreclosure proceedings are initiated against the
         Mortgaged Property as a consequence of an event of default under the
         Mortgage Loan; PROVIDED, FURTHER, that if the related Mortgage has not
         been returned from the applicable recording office, then a copy of such
         Mortgage certified by an authorized officer of the Unaffiliated Seller
         shall be delivered (such original assignment shall be delivered when
          so returned);

                       (iv) The original of any intervening assignments of the
         Mortgage with evidence of recording thereon showing a complete chain of
         assignment from the originator of such Mortgage Loan to the
         Unaffiliated Seller;

                        (v)    The original of any assumption, modification,
         consolidation or  extension agreements with evidence of
         recording thereon; and

                       (vi) The title report or policy of title insurance (or a
         commitment for title insurance if the policy is being held by the title
         insurance company pending recordation of the Mortgage) issued with
         respect to such Mortgage Loan;

PROVIDED, HOWEVER, that in the case of any Mortgage Loans which have been
prepaid in full after the Cut-Off Date and prior to the date of the execution of
this Agreement, the Unaffiliated Seller, in lieu of delivering the above
documents, hereby delivers to the Depositor a certification of an officer of the
Unaffiliated Seller of the nature set forth in Exhibit N attached to the Pooling
and Servicing Agreement; and PROVIDED, FURTHER, HOWEVER, that as to certain
Mortgages or assignments thereof which have been delivered or are being
delivered to recording offices for recording and have not been returned to the
Unaffiliated Seller in time to permit their delivery hereunder at the time of
such transfer, in lieu of delivering such original documents, the Depositor is
delivering to the Trustee a true copy thereof with a certification by the
Unaffiliated Seller on the face of such copy substantially as follows:
"certified true and correct copy of original which has been transmitted for
recordation." The Unaffiliated Seller agrees that it will deliver such original
documents, together with any related title report or policy of title insurance
not previously delivered, on behalf of the Depositor to the Trustee promptly
after they are received, and no later than 120 days after the Closing Date;
PROVIDED, HOWEVER, that in those instances where the public recording office
retains the original Mortgage or assignment of Mortgage after it has been
recorded or such original document has been lost by the recording office, the
Unaffiliated Seller shall be deemed to have satisfied its obligations hereunder
if it shall have delivered to the Trustee a copy of such original Mortgage or
assignment of Mortgage certified by the public recording office to be a true
copy of the recorded original thereof. The Unaffiliated Seller agrees, at its
own expense, to record (or to provide the Trustee with evidence of recordation
thereof) each assignment within 60 days of the Closing Date in the appropriate
public office for real property records, provided that such assignments are
redelivered by the Trustee to the Unaffiliated Seller upon the Unaffiliated
Seller's written request and at the Unaffiliated Seller's expense, unless the
Unaffiliated Seller (at its expense) furnishes to the Trustee, the Certificate
Insurer and the Rating Agencies an Opinion of Counsel reasonably acceptable to
the Trustee and the Certificate Insurer to the effect that recordation of such
assignment is not necessary under applicable state law to preserve the Trustee's
interest in the related Mortgage Loan against the claim of any subsequent
transferee of such Mortgage Loan or any successor to, or creditor of the
Unaffiliated Seller.

          Within a period of 21 days from the Closing Date, the Trustee, at the
Unaffiliated Seller's expense, shall also complete each assignment of Mortgage
such that the final assignment of Mortgage appears in the following form:

                  "Bankers Trust  Company, as Trustee for the benefit of
                  the Certificateholders and  the Certificate Insurer
                  for Preferred Credit Asset-Backed Certificates Series
                  1997- 1."

          (b) In the event that any additional original documents are required
pursuant to the terms of this Section 2.05 to be a part of a Mortgage File, the
Unaffiliated Seller or the Depositor, respectively, shall promptly deliver
written notice to the Trustee that such additional original documents are
required hereunder and deliver such original documents to the Trustee. In acting
as custodian of any such original document, the Servicer agrees further that it
does not and will not have or assert any beneficial ownership interest in the
Mortgage Loans or the Mortgage Files.

          (c) In the event that any Mortgage Note required to be delivered
pursuant to this Section 2.05 is conclusively determined by any of the
Unaffiliated Seller, the Servicer or the Trustee to be lost, stolen or destroyed
the Unaffiliated Seller shall, within 14 days of the Closing Date, deliver to
the Trustee a "lost note affidavit" in form and substance acceptable to the
Trustee, and shall simultaneously therewith request the obligor on such Mortgage
Note to execute and return a replacement Mortgage Note, and shall further agree
to hold the Trustee and the Certificate Insurer harmless from any loss or damage
resulting from any action taken in reliance on the delivery and possession by
the Trustee of such lost note affidavit. Upon the receipt of such replacement
Mortgage Note, the Trustee shall return the lost note affidavit. Delivery by the
Unaffiliated Seller of such lost note affidavit shall not affect the obligations
of the Unaffiliated Seller hereunder with respect to the related Mortgage Loan.

          (d) Promptly after the Closing Date, the Unaffiliated Seller shall,
with respect to each Mortgage Loan, cause to be recorded in the appropriate
public office for real property records, where permitted by applicable law and
where applicable law does not require that a subordinate mortgagee be named as a
party defendant in foreclosure or comparable proceedings in order to foreclose
or otherwise preempt such mortgagee's equity of redemption, a request for notice
of any action by or on behalf of any mortgagee under the related senior lien.

          Section 2.06. ACCEPTANCE OF MORTGAGE LOANS (a) Pursuant to the Pooling
and Servicing Agreement, the Trustee has agreed to execute and deliver on or
prior to the Closing Date an acknowledgment of receipt of' each Mortgage Loan,
the original Mortgage Note with respect to each Mortgage Loan (with any
exceptions noted), in the form attached as Exhibit D to the Pooling and
Servicing Agreement and declares that it will hold such documents and any
amendments, replacements or supplements thereto, as well as any other assets
included in the definition of Trust Fund in the Pooling and Servicing Agreement
and delivered to the Trustee, as Trustee in trust upon and subject to the
conditions set forth in the Pooling and Servicing Agreement for the benefit of
the Certificateholders and the Certificate Insurer. Pursuant to the Pooling and
Servicing Agreement, the Trustee has agreed, for the benefit of the
Certificateholders and the Certificate Insurer, to review (or cause to be
reviewed) each Trustee's Mortgage File within 30 days after the Closing Date
(or, with respect to any Subsequent Mortgage Loan or Qualified Substitute
Mortgage Loan, within 30 days after the receipt by the Trustee thereof) and to
deliver to the initial Certificateholders, the Unaffiliated Seller, the Servicer
and the Certificate Insurer a final certification in the form attached to the
Pooling and Servicing Agreement as Exhibit F to the effect 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 such certification
as not covered by such certification), (i) all documents required to be
delivered to it pursuant to Section 2.3(a)(i) of the Pooling and Servicing
Agreement are in its possession, (ii) each such document has been reviewed by
it, has been, to the extent required, executed and has not been mutilated,
damaged, torn or otherwise physically altered (handwritten additions, changes or
corrections shall not constitute physical alteration if initialed by the
Mortgagor), appears regular on its face and relates to such Mortgage Loan, and
(iii) based on its examination and only as to the foregoing documents, the
information set forth on the Mortgage Loan Schedule accurately reflects the
information set forth in the Trustee's Mortgage File delivered on such date.
Pursuant to the Pooling and Servicing Agreement, the Trustee shall be 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 are other
than what they purport to be on their face.

          (b) The Pooling and Servicing Agreement provides that, if the
Certificate Insurer or the Trustee during the process of reviewing the Trustee's
Mortgage Files finds any document constituting a part of a Trustee's Mortgage
File which is not executed, has not been received, is unrelated to the Mortgage
Loan identified in the Mortgage Loan Schedule, or does not conform to the
requirements of Section 2.05 or the description thereof as set forth in the
Mortgage Loan Schedule, the Trustee or the Certificate Insurer, as applicable,
shall promptly so notify the Servicer, the Unaffiliated Seller, the Certificate
Insurer and the Trustee. The Unaffiliated Seller agrees that in performing any
such review, the Trustee may conclusively rely on the Unaffiliated Seller as to
the purported genuineness of any such document and any signature thereon. The
Unaffiliated Seller agrees to use reasonable efforts to remedy a material defect
in a document constituting part of a Mortgage File of which it is notified. If,
however, within 60 days after such notice the Unaffiliated Seller has not
remedied the defect and the defect materially and adversely affects the interest
of the Certificateholders in the related Mortgage Loan or the interests of the
Certificate Insurer, then the Unaffiliated Seller shall either substitute in
lieu of such Mortgage Loan a Qualified Substitute Mortgage Loan or purchase such
Mortgage Loan in the manner and subject to the conditions set forth in Section
3.05.

          (c) The failure of the Trustee or the Certificate Insurer to give any
notice contemplated herein within the time periods specified above shall not
affect or relieve the Unaffiliated Seller's obligation to repurchase for any
Mortgage Loan pursuant to this Section 2.06 or Section 3.05 of this Agreement.

          Section 2.07. TRANSFER OF MORTGAGE LOANS; ASSIGNMENT OF AGREEMENT. The
Unaffiliated Seller hereby acknowledges and agrees that the Depositor may assign
its interest under this Agreement to the Trustee as may be required to effect
the purposes of the Pooling and Servicing Agreement, without further notice to,
or consent of, the Unaffiliated Seller, and the Trustee shall succeed to such of
the rights and obligations of the Depositor hereunder as shall be so assigned.
The Depositor shall, pursuant to the Pooling and Servicing Agreement, assign all
of its right, title and interest in and to the Mortgage Loans and its right to
exercise the remedies created by Sections 2.06 and 3.05 hereof for breaches of
the representations, warranties, agreements and covenants of the Unaffiliated
Seller contained in Sections 2.05, 2.06, 3.02 and 3.03 hereof to the Trustee for
the benefit of the Certificateholders and the Certificate Insurer. The
Unaffiliated Seller agrees that, upon such assignment to the Trustee, such
representations, warranties, agreements and covenants will run to and be for the
benefit of the Trustee and the Trustee may enforce, without joinder of the
Depositor, the repurchase obligations of the Unaffiliated Seller set forth
herein with respect to breaches of such representations, warranties, agreements
and covenants.

          Section 2.08. EXAMINATION OF MORTGAGE FILES. Prior to the Closing Date
and each Subsequent Transfer Date, as applicable, the Unaffiliated Seller shall
make the related Mortgage Files available to the Depositor or its designee for
examination at the Unaffiliated Seller's offices or at such other place as the
Unaffiliated Seller shall reasonably specify. Such examination may be made by
the Depositor or its designee at any time on or before the Closing Date or
Subsequent Transfer Date, as the case may be. If the Depositor or its designee
makes such examination prior to the Closing Date or Subsequent Transfer Date, as
the case may be, and identifies any Mortgage Loans that do not conform to the
requirements of the Depositor as described in this Agreement, such Mortgage
Loans shall be deleted from the Mortgage Loan Schedule and may be replaced,
prior to the Closing Date or Subsequent Transfer Date, as the case may be, by
substitute Mortgage Loans acceptable to the Depositor. The Depositor may, at its
option and without notice to the Unaffiliated Seller, purchase all or part of
the Mortgage Loans without conducting any partial or complete examination. The
fact that the Depositor or the Trustee has conducted or has failed to conduct
any partial or complete examination of the Mortgage Files shall not affect the
rights of the Depositor or the Trustee to demand repurchase or other relief as
provided in this Agreement.

          Section 2.09. BOOKS AND RECORDS. The sale of each Mortgage Loan shall
be reflected on the Unaffiliated Seller's accounting and other records, balance
sheet and other financial statements as a sale of assets by the Unaffiliated
Seller to the Depositor. The Unaffiliated Seller shall be responsible for
maintaining, and shall maintain, a complete set of books and records for each
Mortgage Loan which shall be clearly marked to reflect the ownership of each
Mortgage Loan by the Trustee for the benefit of the Certificateholders and the
Certificate Insurer. The Seller shall respond to any inquiries from third
parties with respect to ownership of a Mortgage Loan by stating that is not the
owner of such Mortgage Loan and that ownership of such Mortgage Loan is held by
the Trustee on behalf of the Trust Fund.

          Section 2.10. COST OF DELIVERY AND RECORDATION OF DOCUMENTS. The costs
relating to the delivery and recordation of the documents specified in this
Article Two in connection with the Mortgage Loans shall be borne by the
Unaffiliated Seller.

                                  ARTICLE THREE

                         REPRESENTATIONS AND WARRANTIES

          Section 3.01. RESERVED

          Section 3.02. REPRESENTATIONS AND WARRANTIES AS TO THE UNAFFILIATED
SELLER. The Unaffiliated Seller hereby represents and warrants to the Depositor,
as of the Closing Date, that:

          (a) The Unaffiliated Seller is a corporation duly organized, validly
existing and in good standing under the laws of the State of California and has
all licenses necessary to carry on its business as now being conducted and is
licensed, qualified and in good standing in each state where a Mortgaged
Property is located if the laws of such state require licensing or qualification

and to perform its obligations as the Unaffiliated Seller hereunder and under
the Pooling and Servicing Agreement, and in any event the Unaffiliated Seller is
in compliance with the laws of any such state to the extent necessary to ensure
the enforceability of the related Mortgage Loan; the Unaffiliated Seller has the
full power and authority, corporate and otherwise, to execute and deliver this
Agreement and the Pooling and Servicing Agreement and to perform in accordance
herewith and therewith; the execution, delivery and performance of this
Agreement (including all instruments of transfer to be delivered pursuant to
this Agreement and the Pooling and Servicing Agreement) and the Pooling and
Servicing Agreement by the Unaffiliated Seller and the consummation of the
transactions contemplated hereby and thereby have been duly and validly
authorized; each of this Agreement and the Pooling and Servicing Agreement
evidences the valid, binding and enforceable obligation of the Unaffiliated
Seller; and all requisite corporate action has been taken by the Unaffiliated
Seller to make this Agreement and the Pooling and Servicing Agreement valid and
binding upon the Unaffiliated Seller in accordance with its terms;

          (b) No consent, approval, authorization or order of any court or
governmental agency or body is required for the execution, delivery and
performance by the Unaffiliated Seller of or compliance by the Unaffiliated
Seller with the Pooling and Servicing Agreement, this Agreement or the sale of
the Mortgage Loans pursuant to the terms of this Agreement or the consummation
of the transactions contemplated by this Agreement and the Pooling and Servicing
Agreement, or if required, such approval has been obtained prior to the Closing
Date;

          (c) Neither the execution and delivery of this Agreement or the
Pooling and Servicing Agreement, the acquisition or origination of the Mortgage
Loans by the Unaffiliated Seller or the transactions contemplated hereby or
thereby, nor the fulfillment of or compliance with the terms and conditions of
this Agreement or the Pooling and Servicing Agreement, has or will conflict with
or result in a breach of any of the terms, conditions or provisions of the
Unaffiliated Seller's charter or by-laws or any legal restriction or any
agreement or instrument to which the Unaffiliated Seller is now a party or by
which it is bound or to which its property is subject, or constitute a default
or result in an acceleration under any of the foregoing, or result in the
violation of any law, rule, regulation, order, judgment or decree to which the
Unaffiliated Seller or its property is subject, or impair the ability of the
Trustee (or the Servicer as the agent of the Trustee) to realize on the Mortgage
Loans, or impair the value of the Mortgage Loans;

          (d) None of this Agreement, the Pooling and Servicing Agreement or the
information contained in the Prospectus Supplement under the captions
"Description of the Mortgage Loans," "The Unaffiliated Seller" nor any
statement, report or other document prepared by the Unaffiliated Seller and
furnished or to be furnished pursuant to this Agreement, the Pooling and
Servicing Agreement or in connection with the transactions contemplated hereby
or thereby contains any untrue statement or alleged untrue statement of any
material fact or omits to state a material fact necessary to make the statements
contained herein or therein, in light of the circumstances under which they were
made, not misleading;

          (e) There is no action, suit, proceeding or investigation pending or,
to the knowledge of the Unaffiliated Seller, threatened before a court,
administrative agency or government tribunal against the Unaffiliated Seller
which, either in any one instance or in the aggregate, may result in any
material adverse change in the business, operations, financial condition,
properties or assets of the Unaffiliated Seller, or in any material impairment
of the right or ability of the Unaffiliated Seller to carry on its business
substantially as now conducted, or in any material liability on the part of the
Unaffiliated Seller, or which would draw into question the validity of this
Agreement, the Pooling and Servicing Agreement, the Mortgage Loans, or of any
action taken or to be taken in connection with the obligations of the
Unaffiliated Seller contemplated herein or therein, or which would impair
materially the ability of the Unaffiliated Seller to perform under the terms of
this Agreement or the Pooling and Servicing Agreement or that might prohibit its
entering into this Agreement, the Pooling and Servicing Agreement, or the
consummation of any of the transactions contemplated hereby;

          (f) The Unaffiliated Seller is not in violation of or in default with
respect to, and the execution and delivery of this Agreement and the Pooling and
Servicing Agreement by the Unaffiliated Seller and its performance of and
compliance with the terms hereof and thereof will not constitute a violation or
default with respect to, any order or decree of any court or any order,
regulation or demand of any federal, state, municipal or governmental agency,
which violation or default might have consequences that would materially and
adversely affect the condition (financial or other) or operations of the
Unaffiliated Seller or its properties or might have consequences that would
materially and adversely affect its performance hereunder or under the Pooling
and Servicing Agreement;

          (g) Upon the receipt of each Trustee's Mortgage File by the Depositor
under this Agreement, the Depositor will have good title on behalf of the Trust
Fund to each related Mortgage Loan and such other items comprising the corpus of
the Trust Fund free and clear of any lien created by the Unaffiliated Seller
(other than liens which will be simultaneously released);

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

          (i) With respect to any Mortgage Loan purchased by the Unaffiliated
Seller, the Unaffiliated Seller acquired title to the Mortgage Loan in good
faith, without notice of any adverse claim;

          (j) The Unaffiliated Seller does not believe, nor does it have any
reason or cause to believe, that it cannot perform each and every one of its
covenants contained in this Agreement and in the Pooling and Servicing
Agreement. The Unaffiliated Seller is solvent and the sale of the Mortgage Loans
by the Unaffiliated Seller pursuant to the terms of this Agreement will not
cause the Unaffiliated Seller to become insolvent. The sale of the Mortgage
Loans by the Unaffiliated Seller pursuant to the terms of this Agreement was not
undertaken with the intent to hinder, delay or defraud any of the Unaffiliated
Seller's creditors;

          (k) The Mortgage Loans are not intentionally selected in a manner so
as to affect adversely the interests of the Depositor or of any transferee of
the Depositor (including the Trustee);

          (l) The Unaffiliated Seller has determined that it will treat the
disposition of the Mortgage Loans pursuant to this Agreement as a sale for
accounting and tax purposes;

          (m) The Unaffiliated Seller has not dealt with any broker or agent or
anyone else that may be entitled to any commission or compensation in connection
with the sale of the Mortgage Loans to the Depositor other than to the Depositor
or an Affiliate thereof; and

          (n) The consideration received by the Unaffiliated Seller upon the
sale of the Mortgage Loans under this Agreement constitutes fair consideration
and reasonably equivalent value for the Mortgage Loans.

          Section 3.03. REPRESENTATIONS AND WARRANTIES RELATING TO THE MORTGAGE
LOANS. The Unaffiliated Seller represents to the Depositor that, as of the
Closing Date, as to each Initial Mortgage Loan, and as of the Subsequent
Transfer Date, as to each Subsequent Mortgage Loan to be transferred on such
Subsequent Transfer Date, immediately prior to the sale and transfer of such
Mortgage Loan by the Unaffiliated Seller to the Depositor:

          (a) The Mortgage Loans had, as of the Initial Cut-Off Date, an
aggregate Principal Balance equal to $159,047,527.33, and all of the information
set forth in the Mortgage Loan Schedule is complete, true and correct;

          (b) All payments required to be made up to the Cut-Off Date for the
Mortgage Loan under the terms of the Mortgage Note have been made and credited,
except, unless otherwise specified on the Mortgage Loan Schedule, no payment
required under the Mortgage Loan is more than 30 days Delinquent nor has any
payment under the Mortgage Loan been Delinquent for more than 30 days more than
once in the 12 months preceding the Cut-Off Date;

          (c) Except as described in clause (b) above, there are no defaults in
complying with the terms of the Mortgage, and all taxes, governmental
assessments, insurance premiums, water, sewer and municipal charges which have
become liens against the Mortgaged Property, leasehold payments or ground rents
which previously became due and owing have been paid. The Unaffiliated 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;

          (d) The terms of the Mortgage Note and Mortgage have not been
impaired, waived, altered or modified in any respect, except by a written
instrument which has been recorded, if necessary, to protect the interests of
the Trustee on behalf of the Certificateholders and the Certificate Insurer and
which has been delivered to the Trustee. The substance of any such waiver,
alteration or modification has been approved by the title insurer, to the extent
required by the policy, and its terms are reflected on the Mortgage Loan
Schedule. No Mortgagor has been released, in whole or in part, except in
connection with an assumption agreement, which assumption agreement is part of
the Mortgage File delivered to the Trustee and the terms of which are reflected
in the Mortgage Loan Schedule;

          (e) The Mortgage Loan is not subject to any right of rescission,
set-off, counterclaim or defense, including, without limitation, the defense of
usury, nor will the operation of any of the terms of the Mortgage Note or the
Mortgage, or the exercise of any right thereunder, render either the Mortgage
Note or the Mortgage unenforceable, in whole or in part, or subject to any right
of rescission, set-off, recoupment, counterclaim or defense, including, without
limitation, the defense of usury, and no such right of rescission, set-off,
recoupment, counterclaim or defense has been asserted with respect thereto, and
no Mortgagor was a debtor in any state or federal bankruptcy or insolvency
proceeding at the time the Mortgage Loan was originated;

          (f) Pursuant to the terms of the Mortgage, the Mortgaged Property is
subject to fire and casualty insurance with a standard mortgagee clause and
extended coverage which provides guaranteed replacement value of the
improvements securing such Mortgage Loan, or coverage in the amount of the full
replacement value of the improvements securing such Mortgage Loan or the amount
of the unpaid principal balance of the first mortgage plus the unpaid principal
balance of the Mortgage Loan, whichever is less. The fire and casualty insurance
is standard in the industry for property similar (in terms of property type,
value and location) to the Mortgage Loans. If the Mortgaged Property is in an
area identified in the Federal Register by the Federal Emergency Management
Agency as having special flood hazards (and such flood insurance has been made
available), a flood insurance policy is in effect with respect to the Mortgaged
Property meeting the requirements of the current guidelines of the Federal
Insurance Administration with a generally acceptable insurance carrier, in an
amount representing coverage not less than the least of (i) the unpaid principal
balance of the Mortgage Loan, (ii) the full insurable value of the Mortgaged
Property or (iii) the maximum amount of insurance available under the Flood
Disaster Protection Act of 1973. To the best of the Unaffiliated Seller's
knowledge, all such insurance policies (collectively, the "hazard insurance
policy") meet the requirements of the current guidelines of the Federal
Insurance Administration, conform to the requirements of the FNMA Sellers' Guide
and the FNMA Servicers' Guide, and are a standard policy of insurance for the
locale where the Mortgaged Property is located. It is understood and agreed that
such insurance is with insurers approved by the Servicer and that no earthquake
or other additional insurance is to be required of any Mortgagor or to be
maintained on property acquired in respect of a defaulted loan, other than
pursuant to such applicable laws and regulations as shall at any time be in
force and as shall require such additional insurance. The hazard insurance
policy names the Mortgagor as the insured and contains a standard mortgage loss
payable clause in favor of the Unaffiliated Seller, and its successors and
assigns. The Unaffiliated Seller has caused and will cause to be performed any
and all acts required to be performed to preserve the rights and remedies of the
Trustee in any hazard insurance policies applicable to the Mortgage Loans
including, without limitation, any necessary notifications of insurers and
assignments of policies or interests therein. The Mortgage obligates the
Mortgagor thereunder to maintain the hazard 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 such Mortgagor's cost
and expense, and to seek reimbursement therefor from the Mortgagor; PROVIDED,
however, that the addition of any such cost shall not be taken into account for
purposes of calculating the principal amount of the Mortgage Note or the
Mortgage Loan secured by the Mortgage Note. Where required by state law or
regulation, the Mortgagor has been given an opportunity to choose the carrier of
the required hazard insurance, provided the policy is not a "master" or
"blanket" hazard insurance policy covering a condominium or the common
facilities of a planned unit development. To the best of Seller's knowledge, the
hazard insurance policy is the valid and binding obligation of the insurer, is
in full force and effect, and will be in full force and effect and inure to the
benefit of the Trustee upon the consummation of the transactions contemplated by
this Agreement. The Unaffiliated Seller has not engaged in, and has no knowledge
of the Mortgagor's or any Subservicer's having engaged in, any act or omission
which would impair the coverage of any such policy, the benefits of the
endorsement provided for herein, or the validity and binding effect of either.
To the best of Seller's knowledge, in connection with the issuance of the hazard
insurance policy, no unlawful fee, commission, kickback or other unlawful
compensation or value of any kind has been or will be received, retained or
realized by any attorney, firm or other person or entity, and no such unlawful
items have been received, retained or realized by the Unaffiliated Seller;

          (g) Any and all requirements of any federal, state or local law,
including, without limitation, usury, truth-in-lending, real estate settlement
procedures, consumer credit protection, equal credit opportunity or disclosure
laws applicable to the Mortgage Loan have been complied with and the
consummation of the transactions contemplated hereby will not involve the
violation of any such laws;

          (h) The Mortgage has not been satisfied, canceled, subordinated (other
than in connection with a refinancing of the first mortgage on the Mortgaged
Property) or rescinded, in whole or in part, and the Mortgaged Property has not
been released from the lien of the Mortgage, in whole or in part, nor has any
instrument been executed that would effect any such release, cancellation,
subordination or rescission. The Unaffiliated Seller has not waived the
performance by the Mortgagor of any action, if the Mortgagor's failure to
perform such action would cause the Mortgage Loan to be in default, nor has the
Unaffiliated Seller waived any default resulting from any action or inaction by
the Mortgagor;

          (i) The Mortgaged Property is located in the state identified in the
Mortgage Loan Schedule and consists of a fee simple estate in a one or more
parcels of real property improved by a one- to four-family residential dwelling;

          (j) The Mortgage is a valid, subsisting, enforceable and perfected
lien on the Mortgaged Property, including all buildings on the Mortgaged
Property and all installations and mechanical, electrical, plumbing, heating and
air conditioning systems located in or annexed to such buildings, and all
additions, alterations and replacements made at any time with respect to the
foregoing. The lien of the Mortgage is subject only to:

                   (i)     in the case of Mortgage Loans in a second
         priority lien position, a first  mortgage;

                  (ii)     in the case of Mortgage Loans in a third priority
         position, a first and  second mortgage;

                 (iii)     the lien of current real property taxes and
         assessments not yet due and  payable;

                  (iv)    covenants, conditions and restrictions, rights of way,
         easements and other matters of the public record as of the date of
         recording acceptable to prudent mortgage lending institutions generally
         and specifically referred to in the lender's title report delivered to
         the originator of the Mortgage Loan and referred to or otherwise
         considered in the appraisal made for the originator of the Mortgage
         Loan; and

                   (v)     other matters to which like properties are
         commonly subject which do not  materially interfere with
         the benefits of the security intended to be provided by the
          Mortgage or the use, enjoyment, value or marketability of the related
         Mortgaged Property.

Any security agreement, chattel mortgage or equivalent document related to and
delivered in connection with the Mortgage Loan establishes and creates a valid,
subsisting and enforceable junior lien and junior priority security interest on
the property described therein and immediately prior to the sale of such
Mortgage Loan to the Depositor pursuant to this Agreement, the Seller had full
right to sell and assign the same to the Depositor; as of the date of
origination of the Mortgage Loan, the Mortgage Property was not subject to a
Mortgage, deed of trust, deed to secure debt or other security instrument
creating a lien subordinate to the lien of the Mortgage.

          (k) The Mortgage Note and the Mortgage and every other agreement, if
any, executed and delivered by the Mortgagor in connection with the Mortgage
Loan are genuine, and each is the legal, valid and binding obligation of the
maker thereof enforceable in accordance with its terms, subject to the effect of
bankruptcy, insolvency, reorganization, moratorium, receivership, or other
similar laws of general applicability relating to or affecting creditors' rights
generally. All parties to the Mortgage Note and the Mortgage and any other
related agreement had legal capacity to enter into the Mortgage Loan and to
execute and deliver the Mortgage Note, the Mortgage and such other related
agreements, and the Mortgage Note and the Mortgage and such other related
agreements have been duly and properly executed by such parties. The
Unaffiliated Seller has reviewed, or has caused to be reviewed, all of the
documents constituting the Mortgage File and have made such inquiries as it
deems necessary to make and confirm the accuracy of the representations set
forth herein;

          (l) The Mortgage Loan has been closed and any proceeds of the Mortgage
Loan drawn by the Mortgagor as of the Cut-Off Date have been fully disbursed and
there is no requirement for future advances thereunder. All costs, fees and
expenses incurred in making or closing the Mortgage Loan and the recording of
the Mortgage were paid or will be paid, and the Mortgagor is not entitled to any
refund of any amounts paid or due under the Mortgage Note or Mortgage;

          (m) At the time of the sale of the Mortgage Loan to the Depositor
under this Agreement, (i) the Unaffiliated Seller was the sole owner and holder
of the Mortgage Loan, (ii) the Mortgage Loan was not assigned to any Person
other than the Trustee on behalf of the Trust Fund, or pledged, unless such
assignment or pledge has been duly released, (iii) the Unaffiliated Seller had
good, indefeasible and marketable title thereto, (iv) the Unaffiliated Seller
had full right to transfer and sell the Mortgage Loan therein to the Depositor
free and clear of any encumbrance, equity interest, participation interest,
lien, pledge, charge, claim or security interest, and (v) the Unaffiliated
Seller had full right and authority subject to no interest or participation of,
or agreement with, any other party, to sell and assign each Mortgage Loan to the
Depositor under this Agreement, and following the sale of each Mortgage Loan,
the Depositor will own such Mortgage Loan free and clear of any encumbrance,
equity interest, participation interest, lien, pledge, charge, claim or security
interest;

          (n) All parties which had any interest in the Mortgage Loan, whether
as mortgagee, assignee, pledgee or otherwise, and including, without limitation,
the Unaffiliated Seller, are (or, during the period in which they held and
disposed of such interest, were) (i) in compliance with any and all applicable
licensing requirements of the laws of the state wherein the Mortgaged Property
is located to the extent required to avoid a material adverse effect to the
interest of the Trustee on behalf of the Certificateholders and the Certificate
Insurer, and (ii) (1) organized under the laws of such state, or (2) qualified
to do business in such state, or (3) federal savings and loan associations,
savings banks, or national banks having principal offices in such state, or (4)
not doing business in such state;

          (o) The Mortgage Loan has an original Combined Loan-to-Value Ratio
(calculated at the time of origination by dividing the outstanding principal
amount of the first and second Mortgage Loan by the appraised value of the
Mortgaged Property) equal to or less than 125%;

          (p) Each Mortgage Loan was originated pursuant to a title report or a
limited liability lender's title insurance policy or other generally acceptable
form of policy of insurance issued by a title insurer qualified to do business
in the jurisdiction, where the Mortgaged Property is located, evidencing the
Unaffiliated Seller, its successors and assigns, of the priority of its lien of
the Mortgage in the original principal amount of the Mortgage Loan, and subject
only to the exceptions contained in clauses (i), (ii), (iii) and (iv) of
paragraph (j) above. Where required by state law or regulation, the Mortgagor
has been given the opportunity to choose the carrier of the required mortgage
title insurance. Immediately prior to the sale of the Mortgage Loan to the
Depositor under the terms of this Agreement, the Unaffiliated Seller, its
successors and assigns were the sole insurers of such lender's title insurance
policy. Such lender's 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. No claims have been made under such lender's
title insurance policy, and no prior holder of the Mortgage, including the
Unaffiliated Seller, has done, by act or omission, anything which would impair
the coverage of such lender's title insurance policy. In connection with the
issuance of such lender's title insurance policy, no unlawful fee, commission,
kickback or other unlawful compensation or value of any kind has been or will be
received, retained or realized by any attorney, firm or other person or entity,
and no such unlawful items have been received, retained or realized by the
Unaffiliated Seller;

          (q) Except as described in clause (b) above, there is no default,
breach, violation or event of acceleration existing under the Mortgage or the
Mortgage Note and no event which, with the passage of time or with notice and
the expiration of any grace or cure period, would constitute a default, breach,
violation or event of acceleration, and neither the Unaffiliated Seller nor its
predecessors have waived any default, breach, violation or event of
acceleration;

          (r) To the best of the Unaffiliated Seller's knowledge, there are no
mechanics' or similar liens or claims which have been filed for work, labor or
material (and no rights are outstanding that under the law could give rise to
such liens) affecting the related Mortgaged Property which are or may be liens
prior to, or equal or coordinate with, the lien of the related Mortgage;

          (s) To the best of the Unaffiliated Seller's knowledge, all
improvements which were considered in determining the Appraised Value of the
Mortgaged Property lay wholly within the boundaries and building restriction
lines of the Mortgaged Property and no improvements on adjoining properties
encroach upon the Mortgaged Property. To the best of Seller's knowledge, no
improvement located on or being part of the Mortgaged Property is in violation
of any applicable zoning law or regulation; provided, that in no event shall a
legal nonconforming use of the Mortgaged Property be considered a violation of
any such zoning law or regulation;

          (t) The Mortgage Note is payable on the day specified in such Mortgage
Note;

          (u) 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, and (ii) otherwise by judicial foreclosure. Upon
default by a Mortgagor on a Mortgage Loan and foreclosure on, or trustee's sale
of, the Mortgaged Property pursuant to the proper procedures, the holder of the
Mortgage Loan will be able to deliver good and merchantable title to the
Mortgaged Property. There is no homestead or other exemption available to the
Mortgagor which would interfere with the right to sell the Mortgaged Property at
a trustee's sale or the right to foreclose the Mortgage subject to applicable
federal and state laws and judicial precedent with respect to bankruptcy and
right of redemption;

          (v) To the best of Seller's knowledge, all inspections, licenses and
certificates required to be made are issued with respect to all occupied
portions of the Mortgaged Property and with respect to the use and occupancy of
the same, including, but not limited to, certificates of occupancy and fire
underwriting certificates, have been made or obtained from the appropriate
authorities;

          (w) 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 referred to in
(j) above;

          (x) No fees or expenses are or will become payable by the Trustee out
of the assets of the Trust Fund to the trustee under the deed of trust, except
in connection with a trustee's sale after default by the Mortgagor, provided
that this representation and warranty shall in no way obligate the Trustee to
pay any such amounts;

          (y) The Mortgage Note, the Mortgage, the related Assignment of
Mortgage and any other documents required to be delivered by the Unaffiliated
Seller have been delivered to the Trustee in accordance with the Pooling and
Servicing Agreement. The Trustee is in possession of a complete, true and
accurate Mortgage File in accordance with the Pooling and Servicing Agreement;

          (z) The Mortgage contains a 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, at the option of the Mortgagee;

          (aa) Each of the Mortgage and the Assignment of Mortgage is in
recordable form and is acceptable for recording under the laws of the
jurisdiction in which the Mortgaged Property is located:

          (ab) The Mortgage Loan does not contain provisions pursuant to which
Monthly Payments are paid or partially paid with funds deposited in any separate
account established by the Unaffiliated Seller, the Mortgagor or anyone on
behalf of the Mortgagor, or paid by any source other than the Mortgagor, nor
does it contain any other similar provisions currently in effect 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;

          (ac) There is no proceeding pending or, to the best of Seller's
knowledge, threatened, for the total or partial condemnation of the Mortgaged
Property; the Mortgaged Property is undamaged by waste, fire, earthquake or
earth movement, windstorm, flood, tornado, other types of water damage, or other
casualty so as to affect adversely the value of the Mortgaged Property as
security for the Mortgage Loan or the use for which the premises were intended
and each Mortgaged Property is in good repair; and there have not been any
condemnation proceedings with respect to the Mortgaged Property and the
Unaffiliated Seller has no knowledge of any such proceedings in the future;

          (ad) The origination and collection practices with respect to the
Mortgage Loan have been, and in all respects are in accordance with Accepted
Servicing Practices, and with all applicable laws and regulations;

          (ae) The Mortgage File contains an appraisal of the related Mortgage
Property of the Mortgage Loan application by an independent appraiser acceptable
to the Unaffiliated Seller;

          (af) The Mortgagor has not notified the Unaffiliated Seller, and the
Unaffiliated Seller has no knowledge of any relief requested or allowed to the
Mortgagor under the Soldiers' and Sailors' Civil Relief Act of 1940;

          (ag) There exists no violation of any local, state, or federal
environmental law, rule or regulation in respect of the Mortgaged Property which
violation has or could have a material adverse effect on the market value of
such Mortgaged Property. There is no pending action or proceeding directly
involving the related Mortgaged Property in which compliance with any
environmental law, rule or regulation is in issue; and nothing further remains
to be done to satisfy in full all requirements of each such law, rule or
regulation constituting a prerequisite to the use and employment of such
Mortgaged Property;

          (ah) Any and all requirements of any federal, state or local law,
including, without limitation, usury, truth-in-lending, real estate settlement
procedures, consumer credit protection, equal credit opportunity or disclosure
laws, applicable to the Mortgage Loan have been complied with, and the
Unaffiliated Seller has and shall maintain its possession, available for the
Trustee's inspection, and shall deliver to the Trustee upon demand, evidence of
compliance with all such requirements;

          (ai) The Mortgage Loans are representative of the mortgage loans in
the Unaffiliated Seller's portfolio of closed-end fixed rate loans secured by
one-to-four family residential properties;

          (aj) All information regarding the Mortgage Loans which could
reasonably be expected to adversely affect the value or the marketability of any
Mortgaged Property or Mortgage Loan and of which the Unaffiliated Seller is
aware has been provided by the Unaffiliated Seller to the Depositor and the
Certificate Insurer;

          (ak) The Mortgage Loan was originated in accordance with the
underwriting criteria of the Unaffiliated Seller and was underwritten in
accordance therewith. The documents, instruments and agreements submitted for
loan underwriting and the documents constituting a part of the Mortgage File
were not falsified by or with the knowledge of the Unaffiliated Seller and
contain no untrue statement of material fact and do not omit to state a material
fact required to be stated therein or necessary to make the information and
statements therein not misleading. The Unaffiliated Seller has not made any
representations to the Mortgagor that are inconsistent with the mortgage
instruments used;

          (al) All amounts, with respect to the Mortgage Loans, received after

or assessment lien on the Mortgage Property;

          (an) The Unaffiliated Seller has performed or directed the Servicer to
perform any and all acts required to be performed to preserve the rights and
remedies of the Trustee in any insurance policies applicable to the Mortgage
Loan, including, without limitation, any necessary notification of insurers,
assignments of policies (other than the title policy) or interests therein, and
establishment of co-insurer, joint loan payer and mortgagee rights in favor of
the Trustee;

          (ao) The Mortgage Loan conforms, and all such Mortgage Loans in the
aggregate conform, to the description thereof set forth in the Prospectus

          (at) As of the Closing Date, there is no valid offset, defense or
counterclaim to any Mortgage, including, without limitation, any offset,
defense, or counterclaim against the obligation to pay principal and interest in
accordance with the Mortgage;

          (au) As of the Closing Date, each Mortgage Loan and Mortgage is an
enforceable obligation of the related Mortgagor, except as enforceability may be

creditors' rights in general and except as such enforceability may be limited by
general principles of equity (whether considered in a proceeding at law or in
equity); no instrument of release or waiver has been executed in connection with

          (bk) The Mortgage Loans constitute "obligations principally secured by
an interest in real property" for the purpose of Code Section 860G(a)(3)(A) and
Treasury Regulations ss.1.860G-2 issued thereunder. For this purpose a Mortgage
Loan constitutes "obligations principally secured by an interest in real
property" if such Mortgage Loan satisfies either of the following:

                  (1)      The 80-percent test.  An obligation is
                           principally secured by an interest in  real
                           property if the fair market value of the interest
                           in real property  securing the obligation

                           A.       was at least equal to 80 percent of the 
                                    adjusted issue price of the obligation at 
                                    the time the obligation was originated (or, 
                                    if later, but before the Closing Date or 
                                    Subsequent Transfer Date, as applicable, 
                                    the time the obligation was significantly 
                                    modified, as such term is defined in 
                                    Treasury Regulations ss. 1.860G-2,); or

                           B.       is at least equal to 80 percent of the
                                    adjusted issue price of the obligation on
                                    the Closing Date or Subsequent Transfer
                                    Date, as applicable.

                  For purposes of this paragraph (1), the fair market value of
                  the real property interest must be first reduced by the amount
                  of any lien on the real property interest that is senior to 
                  the obligation being tested, and must be further reduced by a 
                  proportionate amount of any lien that is in parity with the 
                  obligation being tested, in each case before the percentages 
                  set forth in (1)(A) and (1)(B) are determined. The adjusted 
                  issue price of an obligation is its issue price plus the 
                  amount of accrued original issue discount, if any, as of the 
                  date of determination.

                  (2)      Alternative test.  An obligation is principally
                           secured by an interest in real  property if
                           substantially all of the proceeds of the
                           obligation were  used to  acquire or to improve
                           or protect an interest in real property that, at
                           the origination date, is the only security for
                           the obligation.  For purposes of this test, loan
                           guarantees made by the United States or any state
                           (or any  political subdivision, agency, or
                           instrumentality of the United States or of any
                           state), or other third party credit enhancement
                           are not viewed as  additional security for a
                           loan.  An obligation is not considered to be
                           secured by property other than real property
                           solely because the obligor is personally liable
                           on the obligation.  For this purpose only
                           "substantially all of the proceeds of the
                           obligation" can reasonably be concluded to mean
                           at least 80 percent of the gross proceeds.

          Section 3.04. REPRESENTATIONS AND WARRANTIES OF THE DEPOSITOR. The
Depositor hereby represents, warrants and covenants to the Unaffiliated Seller,
as of the date of execution of this Agreement and the Closing Date, that:

          (b) The Depositor has the corporate power and authority to purchase
each Mortgage Loan and to execute, deliver and perform, and to enter into and
consummate all the transactions contemplated by this Agreement;

          (c) This Agreement has been duly and validly authorized, executed and
delivered by the Depositor, and, assuming the due authorization, execution and
delivery hereof by the Unaffiliated Seller, constitutes the legal, valid and
binding agreement of the Depositor, enforceable against the Depositor in
accordance with its terms, except as such enforcement may be limited by
bankruptcy, insolvency, reorganization, moratorium or other similar laws
relating to or affecting the rights of creditors generally, and by general
equity principles (regardless of whether such enforcement is considered in a
proceeding in equity or at law);

          (d) No consent, approval, authorization or order of or registration or
filing with, or notice to, any governmental authority or court is required for
the execution, delivery and performance of or compliance by the Depositor with
this Agreement or the consummation by the Depositor of any of the transactions
contemplated hereby, except such as have been made on or prior to the Closing
Date;

          (e) The Depositor has filed or will file the Prospectus and Prospectus

          (f) Following the final Subsequent Transfer Date, the Depositor will
file a Form 8-K with the Commission containing a description of the Mortgage
Loans acquired by the Trust Fund as of their respective Cut-Off Dates.

          (g) None of the execution and delivery of this Agreement, the purchase
of the Mortgage Loans from the Unaffiliated Seller, the consummation of the
other transactions contemplated hereby, or the fulfillment of or compliance with
the terms and conditions of this Agreement, (i) conflicts or will conflict with

          Section 3.05. REPURCHASE OBLIGATION FOR DEFECTIVE DOCUMENTATION AND
FOR BREACH OF A REPRESENTATION OR WARRANTY. (a) Each of the representations and
warranties contained in Sections 3.01, 3.02 and 3.03 shall survive the purchase
by the Depositor of the Mortgage Loans and the subsequent transfer thereof by
the Depositor to the Trustee and shall continue in full force and effect,
notwithstanding any restrictive or qualified endorsement on the Mortgage Notes
and notwithstanding subsequent termination of this Agreement or the Pooling and
Servicing Agreement.

          (b) With respect to any representation or warranty contained in
Sections 3.02 or 3.03 hereof that is made to the best of the Unaffiliated
Seller's knowledge, if it is discovered by the Servicer, any Subservicer, the
Trustee, the Certificate Insurer, the Depositor or any Certificateholder that
the substance of such representation and warranty was inaccurate as of the
Closing Date (or in the case of the Subsequent Mortgage Loans, as of the
respective Subsequent Transfer Date) and such inaccuracy materially and
adversely affects the value of the related Mortgage Loan or the interest of the
Certificate Insurer, then notwithstanding the Unaffiliated Seller's lack of
knowledge with respect to the inaccuracy at the time the representation or
warranty was made, such inaccuracy shall be deemed a breach of the applicable
representation or warranty. Upon discovery by the Unaffiliated Seller, the
Depositor, the Servicer, any Subservicer, the Trustee, the Certificate Insurer
or any Certificateholder of a breach of any of such representations and
warranties which materially and adversely affects the value of Mortgage Loans or
the interest of the Certificateholders, or which materially and adversely
affects the interests of the Certificate Insurer or the Certificateholders in
the related Mortgage Loan in the case of a representation and warranty relating
to a particular Mortgage Loan (notwithstanding that such representation and
warranty was made to the Unaffiliated Seller's best knowledge), the party
discovering such breach shall give pursuant to Section 3.4 of the Pooling and
Servicing Agreement prompt written notice to the others. Subject to the next to
last paragraph of this Section 3.05, within 60 days of the earlier of its
discovery or its receipt of notice of any breach of a representation or
warranty, the Unaffiliated Seller shall (a) promptly cure such breach in all
material respects, (b) purchase such Mortgage Loan on the next succeeding
Servicer Remittance Date at a purchase price equal to the Principal Balance of
such Mortgage Loan as of the date of purchase, plus the greater of (i) all
accrued and unpaid interest on such Principal Balance and (ii) 30 days' interest
on such Principal Balance, computed at the Mortgage Interest Rate, plus the
amount of any unpaid and accrued Servicing Fees, plus the amount of any
unreimbursed Delinquency Interest Advances and Servicing Advances made by the
Servicer with respect to such Mortgage Loan, or (c) remove such Mortgage Loan
from the Trust Fund (in which case it shall become a Deleted Mortgage Loan) and
substitute one or more Qualified Substitute Mortgage Loans; provided, that, such
substitution is effected not later than the date which is two years after the
Startup Day or at such later date, if the Trustee and the Certificate Insurer
receive an Opinion of Counsel to the effect that such substitution will not
constitute a prohibited transaction for the purposes of the REMIC provisions of
the Code or cause the Upper Tier REMIC or the Lower Tier REMIC to fail to
qualify as a REMIC at any time any Certificates are outstanding; provided,
however, that with respect to any Mortgage Loan for which the representation in
Section 3.03(ac) is breached solely as a result of flood conditions in the
states of Indiana, Kentucky and Ohio, during the period December 1996 through
February 1997, the Unaffiliated Seller shall use its best efforts to substitute
a Qualified Mortgage Loan for each such Mortgage Loan. Any such substitution
shall be accompanied by payment by the Unaffiliated Seller of the Substitution
Adjustment, if any, to the Servicer be deposited in the Collection Account
pursuant to the Pooling and Servicing Agreement.

          (c) As to any Deleted Mortgage Loan for which the Unaffiliated Seller
substitutes a Qualified Substitute Mortgage Loan or Loans, the Unaffiliated
Seller shall effect such substitution by delivering to the Trustee a
certification in the form attached to the Pooling and Servicing Agreement as
Exhibit G, executed by a Servicing Officer and the documents described in
Section 2.05(a) for such Qualified Substitute Mortgage Loan or Loans. Pursuant
to the Pooling and Servicing Agreement, upon receipt by the Trustee of a
certification of a Servicing Officer of such substitution or purchase and, in
the case of a substitution, upon receipt of the related Trustee's Mortgage File,
and the deposit of certain amounts in the Collection Account pursuant to Section
2.4 of the Pooling and Servicing Agreement (which certification shall be in the
form of Exhibit G to the Pooling and Servicing Agreement), the Trustee shall be
required to release to the Servicer for release to the Unaffiliated Seller the
related Trustee's Mortgage File and shall be required to execute, without
recourse, and deliver such instruments of transfer furnished by the Unaffiliated
Seller as may be necessary to transfer such Mortgage Loan to the Unaffiliated
Seller.

          (d) Pursuant to the Pooling and Servicing Agreement, the Servicer
shall deposit in the Collection Account all payments received in connection with
such Qualified Substitute Mortgage Loan or Loans after the date of such
substitution, or related Cut-Off Date, as applicable, set forth in the
Certification delivered to the Trustee. Monthly Payments received with respect
to Qualified Substitute Mortgage Loans on or before the date of substitution or
Cut- Off Date, as applicable, will be retained by the Unaffiliated Seller. The
Trust Fund will own all payments received on the Deleted Mortgage Loan on or
before the date of substitution or Cut-Off Date, as applicable, and the
Unaffiliated Seller shall thereafter be entitled to retain all amounts
subsequently received in respect of such Deleted Mortgage Loan after the date of
substitution or the related Cut-Off Date, as applicable. Pursuant to the Pooling
and Servicing Agreement, the Servicer shall be required to give written notice
to the Trustee and the Certificate Insurer that such substitution has taken
place and shall amend the Mortgage Loan Schedule to reflect the removal of such
Deleted Mortgage Loan from the terms of the Pooling and Servicing Agreement and
the substitution of the Qualified Substitute Mortgage Loan. The parties hereto
agree to amend the Mortgage Loan Schedule accordingly. Upon such substitution,
such Qualified Substitute Mortgage Loan or Loans shall be subject to the terms
of the Pooling and Servicing Agreement and this Agreement in all respects, and
the Unaffiliated Seller shall be deemed to have made with respect to such
Qualified Substitute Mortgage Loan or Loans, as of the date of substitution, the
representations and warranties set forth in Sections 3.02 and 3.03 herein. On
the date of such substitution, the Unaffiliated Seller will remit to the
Servicer and pursuant to the Pooling and Servicing Agreement the Servicer will
deposit into the Collection Account an amount equal to the Substitution
Adjustment, if any.

          (e) It is understood and agreed that the obligations of the
Unaffiliated Seller set forth in Section 2.06 and this Section 3.05 to cure,
purchase or substitute for a defective Mortgage Loan as provided in Section 2.06
and this Section 3.05 constitute the sole remedies of the Depositor, the
Trustee, the Certificate Insurer and the Certificateholders respecting a breach
of the foregoing representations and warranties (other than the representation
and warranty set forth in Section 3.03(g) to the extent of any fines, penalties,
costs or other damages or losses except for the lost economic value of the
Mortgage Loan, the value of which the remedies provided for in Section 2.06 and
this Section 3.05 shall be deemed adequate).

          (f) Any cause of action against the Unaffiliated Seller relating to or
arising out of the breach of any representations and warranties or covenants
made in Sections 2.06, 3.02 or 3.03 shall accrue as to any Mortgage Loan upon
(i) discovery of such breach by any party and notice thereof to the Unaffiliated
Seller, (ii) failure by the Unaffiliated Seller to cure such breach or purchase
or substitute such Mortgage Loan as specified above, and (iii) demand upon the
Unaffiliated Seller by the Trustee for all amounts payable in respect of such
Mortgage Loan.

          (g) Notwithstanding any contrary provision of this Agreement, with
respect to any Mortgage Loan which is not in default or as to which no default
is imminent, no purchase, or substitution pursuant to Section 2.06(b) or this
Section 3.05 shall be made unless the Unaffiliated Seller provides to the
Trustee and the Certificate Insurer an Opinion of Counsel to the effect that
such purchase or substitution would not (i) result in the imposition of taxes on
"prohibited transactions" of the REMIC, as defined in Section 860F of the Code
or a tax on contributions to the Upper Tier REMIC or Lower Tier REMIC under the
REMIC Provisions, or (ii) cause the Upper Tier REMIC or Lower Tier REMIC to fail
to qualify as an Upper Tier REMIC or Lower Tier REMIC at any time that any
Certificates are outstanding. Any Mortgage Loan as to which purchase or
substitution was delayed pursuant to this paragraph shall be purchased or
substituted (subject to compliance with Section 2.06 and this Section 3.05) upon
the earlier of (a) the occurrence of a default or imminent default with respect
to such loan and (b) receipt by the Trustee and the Certificate Insurer of an
Opinion of Counsel to the effect that such purchase or substitution will not
result in the events described in clauses (i) and (ii) of the preceding
sentence.

          (h) Pursuant to the Pooling and Servicing Agreement, upon discovery by
the Unaffiliated Seller, the Servicer, the Trustee, the Certificate Insurer or
any Certificateholder that any Mortgage Loan does not constitute a Qualified
Mortgage, the party discovering such fact shall promptly (and in any event
within 5 days of the discovery) give written notice thereof to the other parties
and the Certificate Insurer. In connection therewith, the Unaffiliated Seller
shall repurchase or substitute a Qualified Substitute Mortgage Loan for the
affected Mortgage Loan within 60 days of the earlier of such discovery by any of
the foregoing parties, or the Trustee's or the Unaffiliated Seller's receipt of
notice, in the same manner as it would a Mortgage Loan for a breach of
representation or warranty contained in Sections 3.02 or 3.03. Pursuant to the
Pooling and Servicing Agreement the Trustee shall reconvey to the Unaffiliated
Seller the Mortgage Loan to be released pursuant hereto in the same manner, and
on the same terms and conditions, as it would a Mortgage Loan repurchased for
breach of a representation or warranty contained in Sections 3.02 or 3.03.


                                  ARTICLE FOUR

                             THE UNAFFILIATED SELLER

          Section 4.01. COVENANTS OF THE UNAFFILIATED SELLER. The Unaffiliated
Seller covenants to the Depositor as follows:

          (a) The Unaffiliated Seller shall cooperate with the Depositor and the
firm of independent certified public accountants retained with respect to the
issuance of the Certificates in making available all information and taking all
steps reasonably necessary to permit the accountants' letters required hereunder
to be delivered within the times set for delivery herein.

          (b) The Unaffiliated Seller agrees to satisfy or cause to be satisfied
on or prior to the Closing Date, all of the conditions to the Depositor's
obligations set forth in Section 5.01 hereof that are within the Unaffiliated
Seller's (or its agents') control.

          (c) The Unaffiliated Seller hereby agrees to do all acts,
transactions, and things and to execute and deliver all agreements, documents,
instruments, and papers by and on behalf of the Unaffiliated Seller as the
Depositor or its counsel may reasonably request in order to consummate the
transfer of the Mortgage Loans to the Depositor and the subsequent transfer
thereof to the Trustee, and the rating, issuance and sale of the Certificates.

          Section 4.02. MERGER OR CONSOLIDATION. The Unaffiliated Seller will
keep in full effect its existence, rights and franchises as a corporation and
will obtain and preserve its qualification to do business as a foreign
corporation, in each jurisdiction necessary to protect the validity and
enforceability of this Agreement or any of the Mortgage Loans and to perform its
duties under this Agreement. Any Person into which the Unaffiliated Seller may
be merged or consolidated, or any corporation resulting from any merger,
conversion or consolidation to which Unaffiliated Seller shall be a party, or
any Person succeeding to the business of the Unaffiliated Seller, shall be
approved by the Certificate Insurer which approval shall not be unreasonably
withheld and in all events shall be the successor of the Unaffiliated Seller
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. The
Unaffiliated Seller shall send notice of any such merger or consolidation to the
Trustee and the Certificate Insurer.

          Section 4.03. COSTS. In connection with the transactions contemplated
under this Agreement and the Pooling and Servicing Agreement, the Unaffiliated
Seller shall promptly pay (or shall promptly reimburse the Depositor to the
extent that the Depositor shall have paid or otherwise incurred): (a) the fees
and disbursements of the Depositor's and the Underwriter's counsel; (b) the fees
of Standard & Poor's Ratings Group and Moody's Investors Service, Inc.; (c) any
of the fees of the Trustee and the fees and disbursements of the Trustee's
counsel; (d) expenses incurred in connection with printing the Prospectus, the
Prospectus Supplement, any amendment or supplement thereto, any preliminary
prospectus and the Certificates; (e) fees and expenses relating to the filing of
documents with the Securities and Exchange Commission (including without
limitation periodic reports under the Exchange Act); (f) the shelf registration
amortization fee (which fee shall equal l/33rd of l% of the amount of the
Certificates) paid in connection with the issuance of Certificates; (g) all of
the initial expenses of the Certificate Insurer including, without limitation,
legal fees and expenses, accountant fees and expenses and expenses in connection
with due diligence conducted on the Mortgage Files; and (h) all accountant's
fees incurred in connection with the accountant's review of the Prospectus
Supplement and information required to be filed in the Form 8-K pursuant to
Sections 2.02(d)(viii) and (ix). For the avoidance of doubt, the parties hereto
acknowledge that it is the intention of the parties that the Depositor shall not
pay any of the Trustee's fees and expenses in connection with the transactions
contemplated by the Pooling and Servicing Agreement. All other costs and
expenses in connection with the transactions contemplated hereunder shall be
borne by the party incurring such expenses.

          Section 4.04. INDEMNIFICATION. (a) (i) The Unaffiliated Seller, agrees
to indemnify and hold harmless the Depositor, each of its directors, each of its
officers who have signed the Registration Statement, and each of its directors
and each person or entity who controls the Depositor 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, to which the Depositor or any
such person or entity may become subject, under the Securities Act or otherwise,
and will reimburse the Depositor and each such controlling person for any legal
or other expenses incurred by the Depositor or such controlling person in
connection with investigating or defending any such loss, claim, damage,
liability or action, 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 required to be
stated therein or necessary to make the statements in the Prospectus Supplement
or any amendment or supplement to the Prospectus Supplement approved in writing
by the Unaffiliated Seller, in 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
information contained in the Prospectus Supplement referred to in Section
3.02(d). This indemnity agreement will be in addition to any liability which the
Unaffiliated Seller may otherwise have.

                  (ii) The Unaffiliated Seller agrees to indemnify and to hold
         the Depositor 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 Depositor may sustain in any
         way related to the failure of any of the Unaffiliated Seller to perform
         its duties in compliance with the terms of this Agreement. The
         Unaffiliated Seller shall immediately notify the Depositor if a claim
         is made by a third party with respect to this Agreement, and the
         Unaffiliated 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 Depositor in respect of such claim.
         Pursuant to the Pooling and Servicing Agreement, the Trustee shall
         reimburse the Unaffiliated Seller in accordance with Section 3.6 of the
         Pooling and Servicing Agreement for all amounts advanced by the
         Unaffiliated Seller pursuant to the preceding sentence except when the
         claim relates directly to the failure of the Unaffiliated Seller to
         perform its duties in compliance with the terms of this Agreement.

          (b) The Depositor agrees to indemnify and hold harmless the
Unaffiliated Seller, each of its directors and each person or entity who
controls the Unaffiliated Seller 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, to which the Unaffiliated Seller or any such
person or entity may become subject, under the Securities Act or otherwise, and
will reimburse the Unaffiliated Seller and any such director or controlling
person for any legal or other expenses incurred by such party or any such
director or controlling person in connection with investigating or defending any
such loss, claim, damage, liability or action, 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 Registration Statement, the Prospectus, the Prospectus
Supplement, any amendment or supplement to the Prospectus or the Prospectus
Supplement or the omission or the alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein,
in 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 other than a statement or omission relating to
the information set forth in subsection (a)(i) of this Section 4.04. This
indemnity agreement will be in addition to any liability which the Depositor may
otherwise have.

          (c) Promptly after receipt by an indemnified party under this Section
4.04 of notice of the commencement of any action, such indemnified party will,
if a claim in respect thereof is to be made against the indemnifying party under
this Section 4.04, notify the indemnifying party in writing of the commencement
thereof, but the omission to so notify the indemnifying party will not relieve
the indemnifying party from any liability which the indemnifying party may have
to any indemnified party hereunder except to the extent such indemnifying party
has been prejudiced thereby. In case any such action is brought against any
indemnified party, and it notifies the indemnifying party of the commencement
thereof, the indemnifying party will be entitled to participate therein and, to
the extent that it may elect by written notice delivered to the indemnified
party promptly after receiving the aforesaid notice from such indemnified party,
to assume the defense thereof with counsel reasonably satisfactory to such
indemnified party. After notice from the indemnifying party to such indemnified
party of its election to assume the defense thereof, the indemnifying party will
not be liable to such indemnified party under this Section 4.04 for any legal or
other expenses subsequently incurred by such indemnified party in connection
with the defense thereof other than reasonable costs of investigation; provided,
however, if the defendants in any such action include both the indemnified party
and the indemnifying party and the indemnified party shall have reasonably
concluded that there may be legal defenses available to it that are different
from or additional to those available to the indemnifying party, the indemnified
party or parties shall have the right to select separate counsel to assert such
legal defenses and to otherwise participate in the defense of such action on
behalf of such indemnified party or parties. The indemnifying party shall not be
liable for the expenses of more than one separate counsel.

          (d) In order to provide for just and equitable contribution in
circumstances in which the indemnity agreement provided for in the preceding
parts of this Section 4.04 is for any reason held to be unavailable to or
insufficient to hold harmless an indemnified party under subsection (a) or
subsection (b) of this Section 4.04 in respect of any losses, claims, damages or
liabilities (or actions in respect thereof) referred to therein, the
indemnifying party shall contribute to the amount paid or payable by the
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) provided, however, that no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. In determining the amount of
contribution to which the respective parties are entitled, there shall be
considered the relative benefits received by the Unaffiliated Seller on the one
hand, and the Depositor on the other, the Unaffiliated Seller's and the
Depositor's relative knowledge and access to information concerning the matter
with respect to which the claim was asserted, the opportunity to correct and
prevent any statement or omission, and any other equitable considerations
appropriate in the circumstances. The Unaffiliated Seller and the Depositor
agree that it would not be equitable if the amount of such contribution were
determined by pro rata or per capita allocation. For purposes of this Section
4.04, each director of the Depositor, each officer of the Depositor who signed
the Registration Statement, and each person, if any who controls the Depositor
within the meaning of Section 15 of the Securities Act, shall have the same
rights to contribution as the Depositor, and each director of Unaffiliated
Seller, and each person, if any who controls the Unaffiliated Seller within the
meaning of Section 15 of the Securities Act, shall have the same rights to
contribution as the Unaffiliated Seller.

          Section 6.01. NOTICES. All demands, notices and communications

Mortgage Securities Corp., 11 Madison Avenue, New York, New York 10010,
Attention: Nita S. Cherry, or to such other address as the Depositor may
designate in writing to the Unaffiliated Seller and if to the Unaffiliated
Seller, addressed to the Unaffiliated Seller at 3347 Michelson Drive, Suite 400,
Irvine, California 92612 Attention: President, or to such other address as the
Unaffiliated Seller may designate in writing to the Depositor.

          Section 6.02. SEVERABILITY OF PROVISIONS. Any part, provision,
representation, warranty or covenant of this Agreement which is prohibited or
which is held to be void or unenforceable shall be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining
provisions hereof. Any part, provision, representation, warranty or covenant of
this Agreement which is prohibited or unenforceable or is held to be void or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction as to any Mortgage Loan shall not invalidate or render
unenforceable such provision in any other jurisdiction. To the extent permitted
by applicable law, the parties hereto waive any provision of law which prohibits
or renders void or unenforceable any provision hereof.

          Section 6.03. AGREEMENT OF UNAFFILIATED SELLER. The Unaffiliated
Seller agrees to execute and deliver such instruments and take such actions as
the Depositor may, from time to time, reasonably request in order to effectuate
the purpose and to carry out the terms of this Agreement.

          Section 6.04. SURVIVAL. The parties to this Agreement agree that the
representations, warranties and agreements made by each of them herein and in
any certificate or other instrument delivered pursuant hereto shall be deemed to
be relied upon by the other party hereto, notwithstanding any investigation
heretofore or hereafter made by such other party or on such other party's
behalf, and that the representations, warranties and agreements made by the
parties hereto in this Agreement or in any such certificate or other instrument
shall survive the delivery of and payment for the Mortgage Loans.

          Section 6.05. EFFECT OF HEADINGS AND TABLE OF CONTENTS. The Article
and Section headings herein and the Table of Contents are for convenience only
and shall not affect the construction hereof.

          Section 6.06. SUCCESSORS AND ASSIGNS. This Agreement shall inure to
the benefit of and be binding upon the parties hereto and their respective
successors and permitted assigns. Except as expressly permitted by the terms
hereof, this Agreement may not be assigned, pledged or hypothecated by any party
hereto to a third party without the written consent of the other party to this
Agreement and the Certificate Insurer; provided, however, that the Depositor may
assign its rights hereunder without the consent of the Unaffiliated Seller.

          Section 6.07. CONFIRMATION OF INTENT: GRANT OF SECURITY INTEREST. It
is the express intent of the parties hereto that the conveyance of the Mortgage
Loans and the related property by the Unaffiliated Seller to the Depositor as
contemplated by this Sale and Purchase Agreement be, and be treated for all
purposes as, a sale of the Mortgage Loans and the related property. It is,
further, not the intention of the parties that such conveyance be deemed a
pledge of the Mortgage Loans and the related property by the Unaffiliated Seller
to the Depositor to secure a debt or other obligation of the Unaffiliated
Seller. However, in the event that, notwithstanding the intent of the parties,
the Mortgage Loans and the related property are held to continue to be property
of the Unaffiliated Seller then (a) this Sale and Purchase Agreement shall also
be deemed to be a security agreement within the meaning of Articles 8 and 9 of
the New York Uniform Commercial Code; (b) the transfer of the Mortgage Loans
provided for herein shall be deemed to be a grant by the Unaffiliated Seller to
the Depositor of a security interest in all of the Unaffiliated Seller's right,
title and interest in and to the Mortgage Loans and all amounts payable on the
Mortgage Loans in accordance with the terms thereof and all proceeds of the
conversion, voluntary or involuntary, of the foregoing into cash, instruments,
securities or other property; (c) the possession by the Depositor or its
respective agents of Mortgage Notes and such other items of property as
constitute instruments, money, negotiable documents or chattel paper shall be
deemed to be "possession by the secured party" for purposes of perfecting the
security interest pursuant to Section 9-305 of the New York Uniform Commercial
Code and the Uniform Commercial Code of any other applicable jurisdiction; and
(d) notifications to persons holding such property, and acknowledgments,
receipts or confirmations from persons holding such property, shall be deemed
notifications to, or acknowledgments, receipts or confirmations from, financial
intermediaries, bailees or agents (as applicable) of the Depositor for the
purpose of perfecting such security interest under applicable law. Any
assignment of the interest of the Depositor pursuant to any provision hereof
shall also be deemed to be an assignment of any security interest created
hereby. The Unaffiliated Seller and the Depositor shall, to the extent
consistent with this Sale and Purchase Agreement, take such actions as may be
necessary to ensure that, if this Sale and Purchase Agreement were deemed to
create a security interest in the Mortgage Loans, such security interest would
be deemed to be a perfected security interest of first priority under applicable
law and will be maintained as such throughout the term of this Agreement.

          Section 6.08. MISCELLANEOUS. This Agreement supersedes all prior
agreements and understandings relating to the subject matter hereof.

          Section 6.09. AMENDMENTS. (a) This Agreement may be amended from time
to time by the Unaffiliated Seller and the Depositor by written Agreement, upon
the prior written consent of the Certificate Insurer, without notice to or
consent of the Certificateholders to cure any ambiguity, to correct or
supplement any provisions herein, to comply with any changes in the Code, or 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 such action shall not, as evidenced by an
Opinion of Counsel, at the expense of the party requesting the change, delivered
to the Trustee and the Certificate Insurer, adversely affect in any material
respect the interests of any Certificateholder (provided that no amendment shall
be deemed to adversely affect in any material respect the interest of any
Certificateholder, and no Opinion of Counsel to that effect shall be required,
if the Person requesting the amendment obtains a letter from Moody's and S&P
stating that such amendment would not result in the downgrading or withdrawal of
the respective ratings then assigned to the Certificates without regard to the
Certificate Insurance Policy); and provided further, that no such amendment
shall reduce in any manner the amount of, or delay the timing of, payments
received on Mortgage Loans which are required to be distributed on any
Certificate without the consent of the Holder of such Certificate, or change the
rights or obligations of any other party hereto without the consent of such
party. The Unaffiliated Seller shall give prompt written notice to Moody's and
S&P of any amendment made pursuant to this Section 6.09 and shall promptly send
copies of any such amendment to Moody's and S&P.

          (b) This Agreement may be amended from time to time by the
Unaffiliated Seller and the Depositor with the consent of the Certificate
Insurer, the Majority Certificateholders and the Holders of the majority of the
Percentage Interest in each of the Class RL and Class RM Certificates 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; provided, however, that no such amendment shall be made unless the
Trustee receives an Opinion of Counsel, at the expense of the party requesting
the change, that such change will not adversely affect the status of the
Upper-Tier REMIC or the Lower-Tier REMIC as a REMIC or cause a tax to be imposed
on such Upper-Tier REMIC or the Lower-Tier REMIC, and provided further, that no
such amendment shall reduce in any manner the amount of, or delay the timing of,
payments received on Mortgage Loans which are required to be distributed on any
Certificate without the consent of the Holder of such Certificate or reduce the
percentage for each Class the Holders of which are required to consent to any
such amendment without the consent of the Holders of 100% of each Class of
Certificates affected thereby.

          (c) It shall not be necessary for the consent of Holders under this
Section to approve the particular form of any proposed amendment, but it shall
be sufficient if such consent shall approve the substance thereof.

          Section 6.10. THIRD-PARTY BENEFICIARIES. The parties agree that each
of the Certificate Insurer and the Trustee is an intended third-party
beneficiary of this Agreement. The parties further agree that Credit Suisse
First Boston Corporation and each of its directors and each person or entity who
controls Credit Suisse First Boston Corporation or any such person, within the
meaning of Section 15 of the Securities Act (each, an "Underwriter Entity") is
an intended third-party beneficiary of this Agreement to the extent necessary to
obtain the benefit of the enforcement of the obligations and covenants of the
Unaffiliated Seller with respect to each Underwriter Entity under Section
4.04(a)(i) of this Agreement.

          SECTION 6.11. GOVERNING LAW, CONSENT TO JURISDICTION; WAIVER OF JURY
TRIAL. (A) THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE
WITH, THE INTERNAL LAWS (AS OPPOSED TO CONFLICT OF LAWS PROVISIONS) OF THE STATE
OF NEW YORK.

          (B) THE DEPOSITOR AND THE UNAFFILIATED SELLER EACH HEREBY SUBMIT TO
THE NON-EXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK AND THE
UNITED STATES DISTRICT COURT LOCATED IN THE BOROUGH OF MANHATTAN IN NEW YORK
CITY, AND EACH WAIVES PERSONAL SERVICE OF ANY AND ALL PROCESS UPON IT AND
CONSENTS THAT ALL SUCH SERVICE OF PROCESS BE MADE BY REGISTERED MAIL DIRECTED TO
THE ADDRESS SET FORTH IN SECTION 6.01 OF THIS AGREEMENT AND SERVICE SO MADE
SHALL BE DEEMED TO BE COMPLETED FIVE DAYS AFTER THE SAME SHALL HAVE BEEN
DEPOSITED IN THE U.S. MAIL, POSTAGE PREPAID. THE DEPOSITOR AND THE UNAFFILIATED
SELLER EACH HEREBY WAIVE ANY OBJECTION BASED ON FORUM NON CONVENIENS, AND ANY
OBJECTION TO VENUE OF ANY ACTION INSTITUTED HEREUNDER AND CONSENTS TO THE
GRANTING OF SUCH LEGAL OR EQUITABLE RELIEF AS IS DEEMED APPROPRIATE BY THE
COURT. NOTHING IN THIS SECTION SHALL AFFECT THE RIGHT OF THE DEPOSITOR AND THE
UNAFFILIATED SELLER TO SERVE LEGAL PROCESS IN ANY OTHER MANNER PERMITTED BY LAW
OR AFFECT EITHER'S RIGHT TO BRING ANY ACTION OR PROCEEDING IN THE COURTS OF ANY
OTHER JURISDICTION.

          (C) THE DEPOSITOR AND THE UNAFFILIATED SELLER EACH HEREBY WAIVE ANY
RIGHT TO HAVE A JURY PARTICIPATE IN RESOLVING ANY DISPUTE, WHETHER SOUNDING IN
CONTRACT, TORT, OR OTHERWISE ARISING OUT OF, CONNECTED WITH, RELATED TO, OR IN
CONNECTION WITH THIS AGREEMENT. INSTEAD, ANY DISPUTE RESOLVED IN COURT WILL BE
RESOLVED IN A BENCH TRIAL WITHOUT A JURY.

          Section 6.12. EXECUTION IN COUNTERPARTS. This Agreement may be
executed in any number of counterparts, each of which so executed shall be
deemed to be an original, but all such counterparts shall together constitute
but one and the same instrument.

                                                              March ___, 1997


To the Addressees Listed
    on the Attached Annex A


                  Re:      Preferred Credit Asset-Backed
                           Certificates, Series 1997-1


Ladies and Gentlemen:

          I have acted as counsel to Preferred Credit Corporation, a California
corporation (the "Seller"), in connection with the execution and delivery of the
following documents:

                   (i)     The Sale and Purchase Agreement, dated as of
          March 27, 1997 (the "Sale Agreement"), between the Unaffiliated Seller
          and Credit Suisse First Boston Mortgage Securities Corp. (the
          "Depositor")

                  (ii) the Pooling and Servicing Agreement, dated as of March 1,
          1997 (the "Pooling and Servicing Agreement"), among the Depositor, the
          Unaffiliated Seller, as seller, Advanta Mortgage Corp. USA, as
          servicer (the "Servicer"), and Bankers Trust Company, as trustee (the
          "Trustee");

                 (iii) the Insurance Agreement, dated as of March 1, 1997 (the
          "Insurance Agreement"), among MBIA Insurance Corporation ("MBIA"), the
          Depositor, the Unaffiliated Seller, the Servicer and the Trustee; and

                  (iv) the Indemnification Agreement, dated as of March ___,
          1997 (the "Indemnification Agreement"), among MBIA, the Unaffiliated
          Seller, the Servicer and Credit Suisse First Boston Corporation.

                  Capitalized terms used herein, but not defined, shall have the
meanings assigned to them in the Pooling and Servicing Agreement.

          I have examined executed copies of the Sale Agreement, the Pooling and
Servicing Agreement, the Insurance Agreement and the Indemnification Agreement
(collectively, the "Documents"). I have also examined a copy of the Class A
Certificates, the Class B Certificates and the Residual Certificates (the
"CERTIFICATES") and the Prospectus Supplement dated March ___, 1997 with respect
to the Class A Certificates (the "PROSPECTUS SUPPLEMENT").

          In addition, I have examined originals or photostatic or certified
copies of all such corporate records of the Unaffiliated Seller, and such
certificates of public officials, certificates of corporate officers, and other
documents, and such questions of law, as I have deemed relevant and necessary as
a basis for the opinions hereinafter expressed. As to certain issues of fact
material to the opinions expressed herein, I have, with your consent, relied to
the extent I deemed appropriate upon certificates and representations of
officers of the Unaffiliated Seller. In making my examinations and rendering the
opinions herein expressed, I have made the following assumptions:

                  (1)      the corporate power of each party (other than the
                           Unaffiliated Seller) to  enter into and perform
                           all of its obligations under each of the
                           Documents;

                  (2)      the due authorization, execution and delivery of the
                           Documents by all parties thereto (other than the
                           Unaffiliated Seller) and the validity and binding
                           effect on all parties (other than the Unaffiliated
                           Seller) of each of the Documents;

                  (3)      the genuineness of all signatures; and

                  (4)      the authenticity of all documents submitted to me
                           as originals and the  conformity to originals of
                           all documents submitted to me as copies.

          The opinion expressed in paragraph 2 below with respect to the
enforceability of the Documents is subject to the following additional
qualifications:

          (a) The effect of bankruptcy, insolvency, reorganization, moratorium,
receivership, or other similar laws of general applicability relating to or
affecting creditors' rights generally.

          (b) The application of general principles of equity, including, but
not limited to, the remedy of specific performance (regardless of whether
enforceability is considered in a proceeding in equity or at law).

          As to Paragraph 5 below, I have assumed that the parties to the Sale
Agreement and the Pooling and Servicing Agreement have performed and will
perform their respective obligations thereunder, including the delivery to the
Trustee, or its agent, of the Mortgage Notes, properly endorsed, and
fully-executed assignments in proper, recordable form from the Unaffiliated
Seller to the Trustee of the Mortgages following payment of legal and sufficient
consideration therefor, without any such Mortgage having been satisfied or
released, or the Mortgage Note discharged, and without the Trustee having actual
or constructive notice of the existence of any claim, lien, charge, mortgage,
security interest, encumbrance or right of the Unaffiliated Seller or the
Depositor, or creditors of the Unaffiliated Seller or the Depositor or others.
Further I have assumed the absence of any defense against enforcement of, or
right of offset against, each such Mortgage Note and the related Mortgage. I
have undertaken no independent review of the Mortgage Loans, including the
Mortgage Notes and the Mortgages, and have relied solely upon the
representations of the Unaffiliated Seller that it has title to the Mortgage
Loans and that the Mortgage Loans are not subject to any liens at the time of
their sale to the Trustee.

          I am admitted to the Bar of the State of California, and express no
opinion as to the laws of any other jurisdiction except as to matters that are
governed by the federal law. All opinions expressed herein are based on laws,
regulations and policy guidelines currently in force and may be affected by
future regulations. Furthermore, no opinion is expressed herein regarding the
applicable state Blue Sky, legal investment or real estate syndication laws.

          Based upon the foregoing and subject to the last paragraph hereof, I
am of the opinion that:

          1. The Unaffiliated Seller is a corporation duly incorporated, validly
existing and in good standing under the laws of the state of California and is
qualified to do business in each state necessary to enable it to perform its
obligations under the Documents. The Unaffiliated Seller has the power and
authority to execute, deliver and perform its obligations under the Documents.

          2. Each of the Documents has been duly authorized, executed and
delivered by the Unaffiliated Seller and each constitutes a valid, legal and
binding agreement of the Unaffiliated Seller and is enforceable against the
Unaffiliated Seller in accordance with their terms.

          3. No consent, approval, authorization or order of, registration or
filing with, or notice to, any governmental authority or court is required under
federal laws, including, without limitation, the Securities Act of 1933, as
amended, or the laws of the State of California, for the execution, delivery and
performance by the Unaffiliated Seller of the Documents, or the offer, issuance,
sale or delivery of the Certificates, except such as have been obtained.

          4. Neither the sale of the Mortgage Loans to the Trust Fund, the
issuance or sale of the Certificates, nor the execution, delivery or performance
by the Unaffiliated Seller of the Documents, conflicts or will conflict with, or
results or will result in a breach of, or constitutes or will constitute a
default under (i) any term or provision of the certificate of incorporation or
by-laws of the Unaffiliated Seller, (ii) any term or provision of any material
agreement, contract, instrument or indenture to which the Unaffiliated Seller is
a party or is bound which has been identified to me by the appropriate officers
of the Unaffiliated Seller, or (iii) any law, rule or regulation of the State of
California or the federal government.

          5. Immediately upon the receipt of the Mortgage Notes and the
accompanying Mortgages by the Trustee, and the receipt by the Unaffiliated
Seller of legal and sufficient consideration therefor, the Trustee shall,
pursuant to the laws of the State of California, be vested with good and
indefeasible title to, and shall be the sole owner of, and shall obtain all
right, title and interest of the Unaffiliated Seller in and to, each Mortgage
Loan, free and clear of any claim, lien, charge, mortgage, security interest,
encumbrance or rights of the Unaffiliated Seller, EXCEPT THAT until such time as
assignments of mortgage are recorded in the name of the Trustee in the
appropriate jurisdictions (x) the Trustee may not, in certain jurisdictions, be
independently able to enforce the Mortgage against the related Mortgaged
Property or the related Mortgagor, (y) the Unaffiliated Seller could record an
assignment of a Mortgage in the name of a third party or record a discharge and
satisfaction of a Mortgage and (z) any notices which may be given to the record
holder of a Mortgage would be given to the Unaffiliated Seller.

          6. To the best of my knowledge, following due inquiry made of the
appropriate officers of the Unaffiliated Seller, there are no actions,
proceedings or investigations pending or, to my knowledge, threatened against
the Unaffiliated Seller before any court, governmental agency or body or other
tribunal (a) asserting the invalidity of the Documents, (b) seeking to prevent
the consummation of any of the transactions contemplated by the Documents, (c)
which would materially and adversely affect the performance by the Unaffiliated
Seller of obligations under, or the validity or enforceability of the Documents.

          I have furnished this opinion as counsel to the Unaffiliated Seller
and it is solely for the benefit of the addressees hereto.

                                       Very truly yours,

                  Class A-6 Certificates

         MBIA Insurance Corporation (the "Insurer"), in consideration of the
payment of the premium and subject to the terms of this Certificate Guaranty
Insurance Policy (this "Policy"), hereby unconditionally and irrevocably
guarantees to any Owner that an amount equal to each full and complete Insured
Payment will be received from the Insurer by Bankers Trust Company, or its
successors, as trustee for the Owners (the "Trustee"), on behalf of the Owners,
for distribution by the Trustee to each Owner of each Owner's proportionate
share of the Insured Payment. The Insurer's obligations hereunder with respect
to a particular Insured Payment shall be discharged to the extent funds equal to
the applicable Insured Payment are received by the Trustee, whether or not such
funds are properly applied by the Trustee. Insured Payments shall be made only
at the time set forth in this Policy and no accelerated Insured Payments shall
be made regardless of my acceleration of the Obligations, unless such
acceleration is at the sole option of the Insurer.

         Notwithstanding the foregoing paragraph, this Policy does not cover
shortfalls, if any, attributable to the liability of the Trust Fund, any REMIC
or the Trustee for withholding taxes, if any (including interest and penalties
in respect of any such liability).

         The Insurer will pay any Insured Payment that is a Preference Amount on
the Business Day following receipt on a Business Day by the Fiscal Agent (as
described below) of (i) a certified copy of the order requiring the return of a
preference payment, (ii) an opinion of counsel satisfactory to the Insurer that
such order is final and not subject to appeal, (iii) an assignment in such form
as is reasonably required by the Insurer, irrevocably assigning to the Insurer
all rights and claims of the Owner relating to or arising under the Obligations
against the debtor which made such preference payment or otherwise with respect
to such preference payment and (iv) appropriate instruments to effect the
appointment of the Insurer as agent for such Owner in any legal proceeding
related to such preference payment, such instruments being in a form
satisfactory to the Insurer, provided that if such documents are received after
12:00 noon New York City time on such Business Day, they will be deemed to be
received on the following Business Day. Such payments shall be disbursed to the
receiver or trustee in bankruptcy named in the final order of the court
exercising jurisdiction on behalf of the Owner and not to any Owner directly
unless such Owner has returned principal or interest paid on the Obligations to
such receiver or trustee in bankruptcy, in which case such payment shall be
disbursed to such Owner.

         The Insurer will pay any other amount payable hereunder no later than
12:00 noon New York City time on the later of the Distribution Date on which the
related Deficiency Amount is due or the third Business Day following receipt in
New York, New York on a Business Day by State Street Bank and Trust Company,
N.A., as Fiscal Agent for the Insurer or any successor fiscal agent appointed by
the Insurer (the "Fiscal Agent") of a Notice (as described below); provided that
if such Notice is received after 12:00 noon New York City time on such Business
Day, it will be deemed to be received on the following Business Day. If any such
Notice received by the Fiscal Agent is not in proper form or is otherwise
insufficient for the purpose of making claim hereunder it shall be deemed not to
have been received by the Fiscal Agent for purposes of this paragraph, and the
Insurer or the Fiscal Agent, as the case may be, shall promptly so advise the
Trustee and the Trustee may submit an amended Notice.

         Insured Payments due hereunder unless otherwise stated herein will be
disbursed by the Fiscal Agent to the Trustee on behalf of the Owners by wire
transfer of immediately available funds in the amount of the Insured Payment
less, in respect of Insured Payments related to Preference Amounts, any amount
held by the Trustee for the payment of such Insured Payment and legally
available therefor.

         The Fiscal Agent is the agent of the Insurer only and the Fiscal Agent
shall in no event be liable to Owners for any acts of the Fiscal Agent or any
failure of the Insurer to deposit, or cause to be deposited, sufficient funds to
make payments due under this Policy.
