Item 2.  Acquisition or Disposition of Assets

Description of the Certificates and the Mortgage Loans

            Advanta Mortgage Conduit Services, Inc. registered an issuance of
$3,500,000,000 in principal amount of Mortgage Loan Asset-Backed Certificates on
a delayed or continuous basis pursuant to Rule 415 under the Securities Act of
1933, as amended (the "Act"), by the Registration Statement on Form S-3 (File
No. 333-37107-02) (the "Registration Statement"). Pursuant to the Registration
Statement, Advanta Mortgage Loan Trust 1998-1 (the "Registrant" or the "Trust")
issued approximately $900,000,000 in aggregate principal amount of its Mortgage
Loan Asset-Backed Certificates, Series 1998-1 (the "Certificates"), on March 19,
1998 (the "Closing Date"). This Current Report on Form 8-K is being filed to
satisfy an undertaking to file copies of certain agreements executed in
connection with the issuance of the Certificates, the forms of which were filed
as Exhibits to the Registration Statement.

            The Certificates were issued pursuant to a Pooling and Servicing
Agreement (the "Pooling and Servicing Agreement") attached hereto as Exhibit
4.1, dated as of March 1, 1998, among Advanta Mortgage Conduit Services, Inc.
(the "Company"), Advanta Mortgage Corp. USA, in its capacity as Master Servicer
(the "Master Servicer") and Bankers Trust Company of California, N.A., in its
capacity as Trustee (the "Trustee"). The Certificates consist of thirteen
classes, the Class A-1 Group I Certificates, the Class A-2 Group I Certificates,
the Class A-3 Group I Certificates, the Class A-4 Group I Certificates, the
Class A-5 Group I Certificates, the Class A-6 Group I Certificates, the Class
A-IO Group I Certificates, the Class A-7 Combination Certificates*, the Class
A-8 Group II Certificates (collectively, the "Class A Certificates"), the Class
M-1 Group II Certificates, the Class M-2 Group II Certificates (together, the
"Mezzanine Certificates"), the Class B-1 Group II Certificates (the "Class B
Certificates" and together with the Mezzanine Certificates, the "Subordinate
Certificates") and the Class R Certificates (Residual Interest) (the "Class R
Certificates"). The Class A Certificates and the Subordinate Certificates,
collectively, are the "Offered Certificates". The Offered Certificates and the
Class R Certificates are together referred to herein as the "Certificates". The
Certificates initially evidence, in the aggregate, 100% of the undivided
beneficial ownership interests in the Trust.

*Owners of the Class A-7 Certificates will be purchasing two separate, undivided
interests in the Mortgage Loans, which interests are represented by the
Component I certificate ("Component I") and the Component II certificate
("Component II"), respectively. Component I represents the interest in Group I;
Component II represents the interest in Group II.
<PAGE>   3
            The assets of the Trust initially will include two investment pools
(each, a "Mortgage Loan Group" or "Group") of closed-end mortgage loans (the
"Mortgage Loans") secured by mortgages or deeds of trust (the "Mortgages") on
one-to-four family residential properties. The Class A Certificates (other than
the Class A-1 Certificates and Class A-7 Certificates) represent undivided
ownership interests in a pool of fixed-rate Mortgage Loans secured by Mortgages
which may be either in a first or in a junior lien position. The Subordinate
Certificates, the Class A-1 Certificates and the Class A-7 Certificates
represent undivided ownership interests in a group of adjustable rate Mortgage
Loans secured by Mortgages which may be either in a first or in a junior lien
position.

            Interest distributions on the Offered Certificates are based on the
Certificate Principal Balance thereof and the then applicable Pass-Through Rate
thereof.

            The Class A-1 Certificates have an aggregate principal amount of
$143,000,000. The Class A-2 Certificates have an aggregate principal amount of
$89,000,000. The Class A-3 Certificates have an aggregate principal amount of
$64,000,000. The Class A-4 Certificates have an aggregate principal amount of
$42,000,000. The Class A-5 Certificates have an aggregate principal amount of
$68,000,000. The Class A-6 Certificates have an aggregate principal amount of
$50,000,000. The Class A-7 Certificates have an aggregate principal amount of
$330,000,000**. The Class A-8 Certificates have an aggregate principal amount of
$44,000,000. The Class M-1 Certificates have an aggregate principal amount of
$26,000,000. The Class M-2 Certificates have an aggregate principal amount of
$23,000,000. The Class B-1 Certificates have an aggregate principal amount of
$21,000,000. No principal payments are distributed with respect to the Class
A-IO Certificates. Interest on the Class A-IO will be distributed and calculated
on the basis of a notional principal balance equal to the aggregate outstanding
Principal Balance of the Class A-6 Certificates (the "Notional Principal
Balance").

            As of the Closing Date, the Mortgage Loans had the characteristics
described in the Prospectus dated October 30, 1997 and the Prospectus Supplement
dated March 12, 1998 filed pursuant to Rule 424(b)(5) of the Act with the
Commission.


**Component I represents $44,000,000 of the original Certificate Principal
Balance of the Class A-7 Combination Certificates; Component II represents
$286,000,000 of the original Certificate Principal Balance of the Class A-7
Combination Certificates.

"Indemnification Agreement") dated as of March __, 1998 among the Underwriters,
the Company and the Insurer, governing the liability of the several parties with
respect to the losses resulting from material misstatements or omissions
contained in the Prospectus Supplement.

Company represents and warrants to, and agrees with the Underwriters that:

                  A. Registration Statements on Form S-3, as amended by
            Post-Effective Amendments thereto, have (i) been prepared by the
            Company in conformity with the requirements of the Securities Act of
            1933 (the "Securities Act") and the rules and regulations (the

            As used in this Agreement, "Effective Time" means the date and the
            time as of which such Registration Statements, or the most recent
            post-effective amendment thereto, if any, was declared effective by
            the Commission; "Effective Date" means the date of the Effective
            Time; "Preliminary Prospectus" means each prospectus included in

            to be used in connection with the sale of the Offered Certificates
            and any prospectus filed with the Commission by the Company with the

            Regulations; "Registration Statement" means such registration

            time; and "Prospectus" means such final prospectus, as first
            supplemented by a prospectus supplement (the "Prospectus

            Preliminary Prospectus or to the Prospectus shall be deemed to refer
            to and include any documents incorporated by reference therein
            pursuant to Item 12 of Form S-3 under the Securities Act, as of the
            date of such Preliminary Prospectus or the Prospectus, as the case
            may be, and any reference to any amendment or supplement to any
            Preliminary Prospectus or the Prospectus shall be deemed to refer to
            and include any document filed under the Securities Exchange Act of
            1934 (the "Exchange Act") after the date of such Preliminary
            Prospectus or the Prospectus, as the case may be, and incorporated

            of the Exchange Act after the Effective Time that is incorporated by
            reference in the Registration Statement. The Commission has not
            issued any order preventing or suspending the use of any Preliminary
            Prospectus. There are no contracts or documents of the Company which
            are required to be filed as exhibits to the Registration Statement
            pursuant to the Securities Act or the Rules and Regulations which
            have not been so filed or incorporated by reference therein on or
            prior to the Effective Date of the Registration Statements. The
            conditions for use of Form S-3, as set forth in the General
            Instructions thereto, have been satisfied.

                  To the extent that any Underwriter (i) has provided to the
            Company Collateral term sheets (as hereinafter defined) that such
            Underwriter has provided to a prospective investor, the Company has

            8-K within two business days of its receipt thereof, or (ii) has

            reasonably practicable after the date of this Agreement, but in any
            event, not later than the date on which the Prospectus is filed with
            the Commission pursuant to Rule 424 of the Rules and Regulations.

                  B. The Registration Statement conforms, and the Prospectus and
            any further amendments or supplements to the Registration Statement
            or the Prospectus will, when they become effective or are filed with
            the Commission, as the case may be, conform in all respects to the
            requirements of the Securities Act and the Rules and Regulations.
            The


                                       3
<PAGE>   4
            Registration Statement, as of the Effective Date thereof and of any
            amendment thereto, did not contain an untrue statement of a material
            fact or omit to state a material fact required to be stated therein
            or necessary to make the statements therein not misleading. The
            Prospectus as of its date, and as amended or supplemented as of the
            Closing Date (as hereinafter defined) does not and will not contain
            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;
            provided that no representation or warranty is made as to
            information contained in or omitted from the Registration Statement
            or the Prospectus in reliance upon and in conformity with written
            information furnished to the Company in writing by the Underwriters
            expressly for use therein.

                  C. The documents incorporated by reference in the Prospectus,
            when they became effective or were filed with the Commission, as the
            case may be, conformed in all material respects to the requirements
            of the Securities Act or the Exchange Act, as applicable, and the
            rules and regulations of the Commission thereunder, and none of such
            documents contained an untrue statement of a material fact or
            omitted to state a material fact required to be stated therein or
            necessary to make the statements therein not misleading; and any
            further documents so filed and incorporated by reference in the
            Prospectus, when such documents become effective or are filed with
            the Commission, as the case may be, will conform in all material

            Indemnification Agreement, the Offered Certificates, the
            Registration Statement and the Prospectus, and all other legal
            matters relating to this Agreement and the transactions contemplated
            hereby shall be satisfactory in all respects to counsel for the
            Underwriters, and the Company shall have furnished to such counsel
            all documents and information that they may reasonably request to
            enable them to pass upon such matters.

                  D. The Representative shall have received the favorable
            opinion of Dewey Ballantine LLP, special counsel to the Company with
            respect to the following items, dated the Closing Date, to the
            effect that:

                  1. The Company has been duly organized and is validly existing
            as a corporation in good standing under the laws of the State of
            Delaware, and is qualified to do business in each state necessary to
            enable it to perform its obligations as Sponsor under the Pooling
            and Servicing Agreement. The Company has the requisite power and
            authority to execute and deliver, engage in the transactions
            contemplated by, and perform and observe the conditions of, this
            Agreement, the Pooling and


                                       11
<PAGE>   12
            Servicing Agreement, the Indemnification Agreement and the Purchase
            Agreement.

                  2. This Agreement, the Certificates, the Pooling and Servicing
            Agreement, the Indemnification Agreement and the Purchase Agreement
            have been duly and validly authorized, executed and delivered by the
            Company, all requisite corporate action having been taken with
            respect thereto, and each (other than the Certificates) constitutes
            the valid, legal and binding agreement of the Company.

                  3. Neither the transfer of the Mortgage Loans to the Trust,
            the issuance or sale of the Certificates nor the execution, delivery
            or performance by the Company of the Pooling and Servicing
            Agreement, this Agreement, the Indemnification Agreement or the
            Purchase Agreement (A) 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 bylaws of the Company; (ii) any term or provision
            of any material agreement, contract, instrument or indenture, to
            which the Company is a party or is bound and known to such counsel;
            or (iii) any order, judgment, writ, injunction or decree of any
            court or governmental agency or body or other tribunal having
            jurisdiction over the Company and known to such counsel; or (B)
            results in, or will result in the creation or imposition of any
            lien, charge or encumbrance upon the Trust Estate or upon the
            Certificates, except as otherwise contemplated by the Pooling and
            Servicing Agreement.

                  4. The endorsement and delivery of each Note, and the
            preparation, delivery and recording of an Assignment with respect to
            each Mortgage is sufficient to fully transfer to the Trustee for the
            benefit of the Owners all right, title and interest of the Company
            in the Note and Mortgage, as noteholder and mortgagee or assignee
            thereof, subject to any exceptions set forth in such opinion, and
            will be sufficient to permit the Trustee to avail itself of all
            protection available under applicable law against the claims of any
            present or future creditors of the Company and to prevent any other
            sale, transfer, assignment, pledge or other encumbrance of the
            Mortgage Loans by the Company from being enforceable.

                  5. No consent, approval, authorization or order of,
            registration or filing with, or notice to, courts, governmental
            agency or body or other tribunal is required under the laws of the
            State of New York, for the execution, delivery and performance of
            the Pooling and Servicing Agreement, this Agreement, the
            Indemnification Agreement, the Purchase Agreement or the offer,
            issuance, sale or delivery of the Certificates or the consummation
            of any other transaction contemplated thereby by the Company, except
            such which have been obtained.


                                       12
<PAGE>   13
                  6. There are no actions, proceedings or investigations, to
            such counsel's knowledge, pending or threatened against the Company
            before any court, governmental agency or body or other tribunal (i)
            asserting the invalidity of the Pooling and Servicing Agreement, the
            Indemnification Agreement, this Agreement, the Purchase Agreement or
            the Certificates, (ii) seeking to prevent the issuance of the
            Certificates or the consummation of any of the transactions
            contemplated by the Pooling and Servicing Agreement, the
            Indemnification Agreement, or this Agreement, (iii) which would
            materially and adversely affect the performance by the Company of
            obligations under, or the validity or enforceability of, the Pooling
            and Servicing Agreement, the Indemnification Agreement, the
            Certificates, the Purchase Agreement or this Agreement or (iv) that
            would adversely affect the status of the Trust Estate as a "real
            estate mortgage investment conduit" ("REMIC") as such term is
            defined in the Internal Revenue Code of 1986, as amended.

                  7. To the best of the knowledge of such counsel, the
            Commission has not issued any stop order suspending the
            effectiveness of the Registration Statement or any order directed to
            any prospectus relating to the Certificates (including the
            Prospectus), and has not initiated or threatened any proceeding for
            that purpose.

                  8. The Registration Statement and the Prospectus (other than
            the financial and statistical data included therein, as to which
            such counsel need express no opinion), including the Incorporated
            Documents, as of the date on which the Registration Statement was
            declared effective and as of the date hereof, comply as to form in
            all material respects with the requirements of the 1933 Act and the
            rules and regulations thereunder and the Exchange Act and the rules
            and regulations thereunder, and such counsel does not know of any
            amendment to the Registration Statement required to be filed, or of
            any contracts, indentures or other documents of a character required
            to be filed as an exhibit to the Registration Statement or required
            to be described in the Registration Statement which has not been
            filed or described as required.

                  9. Neither the qualification of the Pooling and Servicing
            Agreement under the Trust Indenture Act of 1939 nor the registration
            of the Trust created by such Agreement under the Investment Company
            Act of 1940 is presently required.

                  10. The statements in the Prospectus set forth under the
            captions "DESCRIPTION OF THE SECURITIES," "THE POOLING AND SERVICING
            AGREEMENT" and the statements in the Prospectus Supplement set forth
            under the caption "DESCRIPTION OF THE CERTIFICATES," to the extent
            such statements purport to summarize certain provisions of the
            Certificates or of the Pooling and Servicing Agreement, are fair and
            accurate in all material respects.


                                       13
<PAGE>   14
                  11. The statements in the Prospectus and Prospectus Supplement
            set forth under the captions "ERISA CONSIDERATIONS," "CERTAIN
            FEDERAL INCOME TAX CONSEQUENCES," and the statements in the
            Prospectus set forth under the caption "CERTAIN LEGAL ASPECTS OF THE
            MORTGAGE LOANS AND RELATED MATTERS," to the extent that they
            constitute matters of federal, New York or California law, or
            federal, New York or California legal conclusions provide a fair and
            accurate summary of such law or conclusions.

                  12. Assuming that (a) the Trustee causes the Trust created
            under the Pooling and Servicing Agreement to elect, as the Trustee
            has covenanted to do in the Pooling and Servicing Agreement, to be
            treated as a REMIC and (b) the parties to the Pooling and Servicing
            Agreement comply with the terms thereof, the Trust will be treated
            as a REMIC, the Offered Certificates issued pursuant to the Pooling
            and Servicing Agreement will be treated as the "regular interests"
            in the REMIC and the Class R Certificates issued pursuant to the
            Pooling and Servicing Agreement will be treated as the sole
            "residual interest" in the REMIC. The Trust will not be subject to
            tax upon its income or assets by any taxing authority of the State
            of New York or New York City or of the State of California (except
            that no opinion need be expressed with respect to any minimum tax).

                  13. Such opinion shall also relate to comparable matters with
            respect to the Affiliated Originators and Advanta Mortgage Holding
            Company.

                  14. No information has come to such counsel's attention which
            causes them to believe that the Prospectus (other than the financial
            statement and other financial and statistical data contained
            therein, as to which such counsel need express no opinion), as of
            the date thereof, contained any untrue statement of a material fact
            or omitted to state a material fact necessary to make the statements
            therein, in light of the circumstances under which they were made,
            not misleading.

                  15. Such other matters as the Representative may reasonably
            request.

            In rendering its opinions, the counsel described above may rely, as
to matters of fact, on certificates of responsible officers of the Company, the
Trustee and public officials. Such opinions may also assume the due
authorization, execution and delivery of the instruments and documents referred
to therein by the parties thereto other than the Company.

                  E. The Representative shall have received letters, including
            bring-down letters, from Arthur Andersen LLP, dated on or before the
            Closing Date, in form and substance satisfactory to the
            Representative and counsel


                                       14
<PAGE>   15
            for the Underwriters, to the effect that they have performed certain
            specified procedures requested by the Representative with respect to
            the information set forth in the Prospectus and certain matters
            relating to the Company.

                  F. The Offered Certificates shall have received the ratings
            listed on Schedule A hereto, and such ratings shall not have been
            rescinded or downgraded. The Representative and counsel for the
            Underwriters shall have received copies of any opinions of counsel
            supplied to the rating organizations relating to any matters with
            respect to the Certificates. Any such opinions shall be dated the
            Closing Date and addressed to the Underwriters or accompanied by
            reliance letters to the Underwriters or shall state that the
            Underwriters may rely upon them.

                  G. The Representative shall have received from the Company a
            certificate, signed by the president, a senior vice president or a
            vice president of the Company, dated the Closing Date, to the effect
            that the signer of such certificate has carefully examined the
            Registration Statement, the Pooling and Servicing Agreement and this
            Agreement and that, to the best of his or her knowledge based upon
            reasonable investigation:

                  1. the representations and warranties of the Company in this
            Agreement, as of the Closing Date, and in the Pooling and Servicing
            Agreement, the Indemnification Agreement, the Purchase Agreement and
            in all related agreements, as of the date specified in such
            agreements, are true and correct, and the Company has complied with
            all the agreements and satisfied all the conditions on its part to
            be performed or satisfied at or prior to the Closing Date;

                  2. there are no actions, suits or proceedings pending, or to
            the best of such officer's knowledge, threatened against or
            affecting the Company which if adversely determined, individually or
            in the aggregate, would be reasonably likely to adversely affect the
            Company's obligations under the Pooling and Servicing Agreement, the
            Indemnification Agreement, this Agreement or the Purchase Agreement
            in any material way; and no merger, liquidation, dissolution or
            bankruptcy of the Company is pending or contemplated;

                  3. the information contained in the Registration Statement and
            the Prospectus relating to the Company, the Mortgage Loans or the
            servicing procedures of it or its affiliates or subservicer is true
            and accurate in all material respects and nothing has come to his or
            her attention that would lead such officer to believe that the
            Registration Statement or Prospectus includes any untrue statement
            of a material fact or omits to state a material fact necessary to
            make the statements therein not misleading;


                                       15
<PAGE>   16
                  4. the information set forth in the Schedule of Mortgage Loans
            required to be furnished pursuant to the Pooling and Servicing
            Agreement is true and correct in all material respects;

                  5. there has been no amendment or other document filed
            affecting the articles of incorporation or bylaws of the Company
            since December 31, 1997, and no such amendment has been authorized.
            No event has occurred since December 31, 1997, which has affected
            the good standing of the Company under the laws of the State of
            Delaware;

                  6. there has not occurred any material adverse change, or any
            development involving a prospective material adverse change, in the
            condition, financial or otherwise, or in the earnings, business or
            operations of the Company and its subsidiaries, taken as a whole,
            from December 31, 1997;

                  7. on or prior to the Closing Date, there has been no
            downgrading, nor has any notice been given of (A) any intended or
            potential downgrading or (B) any review or possible changes in
            rating the direction of which has not been indicated, in the rating,
            if any, accorded the Company or in any rating accorded any
            securities of the Company, if any, by any "nationally recognized
            statistical rating organization," as such term is defined for
            purposes of the 1933 Act; and

                  8. each person who, as an officer or representative of the
            Company, signed or signs the Registration Statement, the Pooling and
            Servicing Agreement, the Indemnification Agreement, this Agreement,
            or any other document delivered pursuant hereto, on the date of such
            execution, or on the Closing Date, as the case may be, in connection
            with the transactions described in the Pooling and Servicing
            Agreement, the Indemnification Agreement, the Purchase Agreement and
            this Agreement was, at the respective times of such signing and
            delivery, and is now, duly elected or appointed, qualified and
            acting as such officer or representative, and the signatures of such
            persons appearing on such documents are their genuine signatures.

            The Company shall attach to such certificate a true and correct copy
of its certificate or articles of incorporation, as appropriate, and bylaws
which are in full force and effect on the date of such certificate and a
certified true copy of the resolutions of its Board of Directors with respect to
the transactions contemplated herein.

                  H. The Representative shall have received a favorable opinion
            of counsel to the Trustee, dated the Closing Date and in form and
            substance satisfactory to the Representative, to the effect that:

                  1. the Trustee is a national banking association duly
            organized, validly existing and in good standing under the laws of
            the United States


                                       16
<PAGE>   17
            and has the power and authority to enter into and to take all
            actions required of it under the Pooling and Servicing Agreement;

                  2. the Pooling and Servicing Agreement has been duly
            authorized, executed and delivered by the Trustee and the Pooling
            and Servicing Agreement constitutes the legal, valid and binding
            obligation of the Trustee, enforceable against the Trustee in
            accordance with its terms, except as enforceability thereof may be
            limited by (A) bankruptcy, insolvency, reorganization or other
            similar laws affecting the enforcement of creditors' rights
            generally, as such laws would apply in the event of a bankruptcy,
            insolvency or reorganization or similar occurrence affecting the
            Trustee, and (B) general principles of equity regardless of whether
            such enforcement is sought in a proceeding at law or in equity;

                  3. no consent, approval, authorization or other action by any
            governmental agency or body or other tribunal is required on the
            part of the Trustee in connection with its execution and delivery of
            the Pooling and Servicing Agreement or the performance of its
            obligations thereunder;

                  4. the Certificates have been duly executed, authenticated and
            delivered by the Trustee; and

                  5. the execution and delivery of, and performance by the
            Trustee of its obligations under, the Pooling and Servicing
            Agreement do not conflict with or result in a violation of any
            statute or regulation applicable to the Trustee, or the charter or
            bylaws of the Trustee, or to the best knowledge of such counsel, any
            governmental authority having jurisdiction over the Trustee or the
            terms of any indenture or other agreement or instrument to which the
            Trustee is a party or by which it is bound.

            In rendering such opinion, such counsel may rely, as to matters of
fact, on certificates of responsible officers of the Company, the Trustee and
public officials. Such opinion may also assume the due authorization, execution
and delivery of the instruments and documents referred to therein by the parties
thereto other than the Trustee.

                  I. The Representative shall have received from the Trustee a
            certificate, signed by the President, a senior vice president or a
            vice president of the Trustee, dated the Closing Date, to the effect
            that each person who, as an officer or representative of the
            Trustee, signed or signs the Certificates, the Pooling and Servicing
            Agreement or any other document delivered pursuant hereto, on the
            date hereof or on the Closing Date, in connection with the
            transactions described in the Pooling and Servicing Agreement was,
            at the respective times of such signing and delivery, and is now,
            duly elected or appointed, qualified and acting as such officer or
            representative, and the signatures of such persons appearing on such
            documents are their genuine signatures.

<PAGE>   18
                  J. The Policy relating to the Certificates shall have been
            duly executed and issued at or prior to the Closing Date and shall
            conform in all material respects to the description thereof in the
            Prospectus.

                  K. The Representative shall have received a favorable opinion
            of in-house counsel to the Insurer, dated the Closing Date and in
            form and substance satisfactory to counsel for the Underwriters, to
            the effect that:

                  1. The Insurer is a stock insurance corporation, duly
            incorporated and validly existing under the laws of the State of
            Wisconsin. The Insurer is validly licensed to do business in New
            York and is authorized to issue the Policy and perform its
            obligations under the Policy in accordance with the terms thereof.

                  2. The execution and delivery by the Insurer of the Policy,
            and the Indemnification Agreement are within the corporate power of
            the Insurer and have been authorized by all necessary corporate
            action on the part of the Insurer; the Policy has been duly executed
            and is the valid and binding obligation of the Insurer enforceable
            in accordance with its terms except that the enforcement of the
            Policy may be limited by laws relating to bankruptcy, insolvency,
            reorganization, moratorium, receivership and other similar laws
            affecting creditors' rights generally and by general principles of
            equity.

                  3. The Insurer is authorized to deliver the Indemnification
            Agreement, and such agreement has been duly executed and delivered
            and constitute the legal, valid and binding obligations of the
            Insurer enforceable in accordance with its terms except that the
            enforcement of the Indemnification Agreement may be limited by laws
            relating to bankruptcy, insolvency, reorganization, moratorium,
            receivership and other similar laws affecting creditors' rights
            generally and by general principles of equity and by public policy
            considerations relating to indemnification for securities law
            violations.

                  4. No consent, approval, authorization or order of any state
            or federal court or governmental agency or body is required on the
            part of the Insurer, the lack of which would adversely affect the
            validity or enforceability of the Policy; to the extent required by
            applicable legal requirements that would adversely affect validity
            or enforceability of the Policy, the form of the Policy has been
            filed with, and approved by, all governmental authorities having
            jurisdiction over the Insurer in connection with the Policy.

                  5. The Policy is not required to be registered under the
            Securities Act.

                  6. The information set forth under the caption "THE
            CERTIFICATE INSURANCE POLICY" and "THE CERTIFICATE INSURER" in the
            Prospectus forming a part of the Registration Statement, insofar as
            such statements constitute a description of the Policy, accurately
            summarizes the Policy.

            In rendering this opinion, such counsel may rely, as to matters of
fact, on certificates of responsible officers of the Company, the Trustee, the
Insurer and public officials. Such opinion may assume the due authorization,
execution and delivery of the instruments and documents referred to therein by
the parties thereto other than the Insurer.

                  L. On or prior to the Closing Date, there has been no
            downgrading, nor has any notice been given of (A) any intended or
            potential downgrading or (B) any review or possible changes in
            rating the direction of which has not been indicated, in the rating,
            if any, accorded the Insurer's claims paying ability by any
            "nationally recognized statistical rating organization," as such
            term is defined for purposes of the 1933 Act.

                  M. On or prior to the Closing Date, there has been no
            downgrading, nor has any notice been given of (A) any intended or
            potential downgrading or (B) any review or possible changes in
            rating the direction of which has not been indicated, in the rating,
            if any, accorded the Company or in any rating accorded any
            securities of the Company, if any, by any "nationally recognized
            statistical rating organization," as such term is defined for
            purposes of the 1933 Act.

                  N. There has not occurred any change, or any development
            involving a prospective change, in the condition, financial or
            otherwise, or in the earnings, business or operations, since
            December 31, 1997, of (A) the Company and its subsidiaries or (B)
            the Insurer, that is in the Representative's judgment material and
            adverse and that makes it in the Representative's judgment
            impracticable to market the Offered Certificates on the terms and in
            the manner contemplated in the Prospectus.

                  O. The Representative shall have received from the Insurer a
            certificate, signed by the president, a senior vice president or a
            vice president of the Insurer, dated the Closing Date, to the effect
            that the signer of such certificate has carefully examined the
            Policy, the Indemnification Agreement and the related documents and
            that, to the best of his or her knowledge based on reasonable
            investigation:

                  1. There are no actions, suits or proceedings pending or
            threatened against or affecting the Insurer which, if adversely
            determined, individually or in the aggregate, would adversely affect
            the Insurer's performance under the Policy or the Indemnification
            Agreement;


                                       19
<PAGE>   20
                  2. Each person who as an officer or representative of the
            Insurer, signed or signs the Policy, the Indemnification Agreement
            or any other document delivered pursuant hereto, on the date
            thereof, or on the Closing Date, in connection with the transactions
            described in this Agreement was, at the respective times of such
            signing and delivery, and is now, duly elected or appointed,
            qualified and acting as such officer or representative, and the
            signatures of such persons appearing on such documents are their
            genuine signatures;

                  3. The information contained in the Prospectus under the
            captions "THE CERTIFICATE INSURANCE POLICY" and "THE CERTIFICATE
            INSURER" is true and correct in all material respects and does not
            omit to state a material fact with respect to the description of the
            Policy or the ability of the Insurer to meet its payment obligations
            under the Policy;

                  4. The tables regarding the Insurer's capitalization set forth
            under the heading "THE CERTIFICATE INSURANCE POLICY" and "THE
            CERTIFICATE INSURER" presents fairly the capitalization of the
            Insurer as of December 31, 1997;

                  5. On or prior to the Closing Date, there has been no
            downgrading, nor has any notice been given of (A) any intended or
            potential downgrading or (B) any review or possible changes in
            rating the direction of which has not been indicated, in the rating
            accorded the claims paying ability of the Insurer by any "nationally
            recognized statistical rating organization," as such term is defined
            for purposes of the 1933 Act;

                  6. The audited balance sheet of the Insurer as of December 31,
            1997 and the related statement of income and retained earnings for
            the fiscal year then ended, and the accompanying footnotes, together
            with the related opinion of an independent certificated public
            accountant, copies of which are incorporated by reference in the
            Prospectus Supplement, fairly present in all material respects the
            financial condition of the Insurer as of such date and for the
            period covered by such statements in accordance with generally
            accepted accounting principles consistently applied.

                  7. to the best knowledge of such officer, since December 31,
            1997, no material adverse change has occurred in the financial
            position of the Insurer other than as set forth in the Prospectus
            Supplement.

            The officer of the Insurer certifying to items 5-7 shall be an
officer in charge of a principal financial function.


                                       20
<PAGE>   21
            The Insurer shall attach to such certificate a true and correct copy
of its certificate or articles of incorporation, as appropriate, and its bylaws,
all of which are in full force and effect on the date of such certificate.

                  P. The Representative shall have received from Dewey
            Ballantine LLP, special counsel to the Company, a survey in form and
            substance satisfactory to the Representative, indicating the
            requirements of applicable local law which must be complied with in
            order to transfer and service the Mortgage Loans pursuant to the
            Pooling and Servicing Agreement and the Company shall have complied
            with all such requirements.

                  Q. The Representative shall have received from Dewey
            Ballantine LLP, special counsel to the Underwriters, such opinion or
            opinions, dated the Closing Date, with respect to the issuance and
            sale of the Certificates, the Prospectus and such other related
            matters as the Representative shall reasonably require.

                  R. The Representative and counsel for the Underwriters shall
            have received copies of any opinions of counsel to the Company
            supplied to the Trustee relating to matters with respect to the
            Certificates. Any such opinions shall be dated the Closing Date and
            addressed to the Underwriters or accompanied by reliance letters to
            the Underwriters or shall state the Underwriters may rely thereon.

                  S. The Representative shall have received such further
            information, certificates and documents as the Representative may
            reasonably have requested not fewer than three (3) full business
            days prior to the Closing Date.

                  T. There shall have been executed and delivered by Advanta
            Mortgage Holding Company, the corporate parent of the Company
            ("AMHC"), a letter agreement with the Trustee and the Insurer,
            pursuant to which AMHC agrees to become jointly and severally liable
            with the Company and Advanta Mortgage Corp. USA for the payment of
            the Joint and Several Obligations (as defined in such letter
            agreement).

                  U. There shall have been executed and delivered by AMHC, the
            corporate parent of the Company, a letter agreement with the
            Underwriters substantially in the form of Exhibit A hereto.

                  V. Prior to the Closing Date, counsel for the Underwriters
            shall have been furnished with such documents and opinions as they
            may reasonably require for the purpose of enabling them to pass upon
            the issuance and sale of the Offered Certificates as herein
            contemplated and related proceedings or in order to evidence the
            accuracy and completeness of any of the representations and
            warranties, or the fulfillment of any of


                                       21
<PAGE>   22
            the conditions, herein contained, and all proceedings taken by the
            Company in connection with the issuance and sale of the Certificates
            as herein contemplated shall be satisfactory in form and substance
            to the Representative and counsel for the Underwriters.

                  W. Subsequent to the execution and delivery of this Agreement
            none of the following shall have occurred: (i) trading in securities
            generally on the New York Stock Exchange, the American Stock
            Exchange or the over-the-counter market shall have been suspended or
            minimum prices shall have been established on either of such
            exchanges or such market by the Commission, by such exchange or by
            any other regulatory body or governmental authority having
            jurisdiction; (ii) a banking moratorium shall have been declared by
            Federal or state authorities; (iii) the United States shall have
            become engaged in hostilities, there shall have been an escalation
            of hostilities involving the United States or there shall have been
            a declaration of a national emergency or war by the United States;
            or (iv) there shall have occurred such a material adverse change in
            general economic, political or financial conditions (or the effect
            of international conditions on the financial markets of the United
            States shall be such) as to make it, in the judgment of the
            Representative, impractical or inadvisable to proceed with the
            public offering or delivery of the Certificates on the terms and in
            the manner contemplated in the Prospectus.

                  X. The Certificates shall have received the ratings set forth
            on Schedule A hereto.

            If any condition specified in this Section VI shall not have been
fulfilled when and as required to be fulfilled, this Agreement may be terminated
by the Representative by notice to the Company at any time at or prior to the
Closing Date, and such termination shall be without liability of any party to
any other party except as provided in Section VII.

            All opinions, letters, evidence and certificates mentioned above or
elsewhere in this Agreement shall be deemed to be in compliance with the
provisions hereof only if they are in form and substance reasonably satisfactory
to counsel for the Underwriters.

            Section VII. Payment of Expenses. The Company agrees to pay: (a) the
costs incident to the authorization, issuance, sale and delivery of the Offered
Certificates and any taxes payable in connection therewith; (b) the costs
incident to the preparation, printing and filing under the Securities Act of the
Registration Statement and any amendments and exhibits thereto; (c) the costs of
distributing the Registration Statement as originally filed and each amendment
thereto and any post-effective amendments thereof (including, in each case,
exhibits), the Preliminary Prospectus, the Prospectus and any amendment or
supplement to the Prospectus or any document incorporated by reference therein,
all as provided in this Agreement; (d) the costs of reproducing and


                                       22
<PAGE>   23
distributing this Agreement; (e) the fees and expenses of qualifying the Offered
Certificates under the securities laws of the several jurisdictions as provided
in Section V(G) hereof and of preparing, printing and distributing a Blue Sky
Memorandum and a Legal Investment Survey (including related fees and expenses of
counsel to the Underwriters); (f) any fees charged by securities rating services
for rating the Offered Certificates; and (g) all other costs and expenses
incident to the performance of the obligations of the Company; provided that,
except as provided in this Section VII, the Underwriters shall pay their own
costs and expenses, including the costs and expenses of Dewey Ballantine LLP,
any transfer taxes on the Offered Certificates which they may sell and the
expenses of advertising any offering of the Offered Certificates made by the
Underwriters.

            If this Agreement is terminated by the Representative, in accordance
with the provisions of Section VI or Section X, the Company shall reimburse the
Underwriters for their respective reasonable out-of-pocket expenses, including
fees and disbursements of Dewey Ballantine LLP, counsel for the Underwriters.

            Section VIII. Indemnification and Contribution.

                  A. The Company agrees to indemnify and hold harmless each
            Underwriter and each person, if any, who controls such Underwriter
            within the meaning of Section 15 of the Securities Act from and
            against any and all loss, claim, damage or liability, joint or
            several, or any action in respect thereof (including, but not
            limited to, any loss, claim, damage, liability or action relating to
            purchases and sales of the Offered Certificates), to which such
            Underwriter or any such controlling person may become subject, under
            the Securities Act or otherwise, insofar as such loss, claim,
            damage, liability or action arises out of, or is based upon, (i) any
            untrue statement or alleged untrue statement of a material fact
            contained in the Registration Statement, (ii) 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, (iii) any untrue statement or alleged untrue statement
            of a material fact contained in the Prospectus or (iv) 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 shall reimburse such Underwriter and each such
            controlling person promptly upon demand for any legal or other
            expenses reasonably incurred by such Underwriter or such controlling
            person in connection with investigating or defending or preparing to
            defend against any such loss, claim, damage, liability or action as
            such expenses are incurred; provided, however, that the Company
            shall not be liable in any such case to the extent that any such
            loss, claim, damage, liability or action arises out of, or is based
            upon, any untrue statement or alleged untrue statement or omission
            or alleged omission made in any Preliminary Prospectus, the
            Prospectus or the Registration Statement in reliance upon and in
            conformity with written information (including any Derived


                                       23
<PAGE>   24
            Information) furnished to the Company through the Representative
            specifically for inclusion therein; and provided, further, that as
            to any Preliminary Prospectus this indemnity shall not inure to the
            benefit of any Underwriter or any controlling person on account of
            any loss, claim, damage, liability or action arising from the sale
            of the Offered Certificates to any person by such Underwriter if
            such Underwriter failed to send or give a copy of the Prospectus, as
            amended or supplemented, to that person within the time required by
            the Securities Act, and the untrue statement or alleged untrue
            statement of a material fact or the omission or alleged omission to
            state a material fact in the Preliminary Prospectus was corrected in
            the Prospectus, unless such failure resulted from non-compliance by
            the Company with Section V(C). For purposes of the last proviso to
            the immediately preceding sentence, the term "Prospectus" shall not
            be deemed to include the documents incorporated therein by
            reference, and none of the Underwriters shall be obligated to send
            or give any supplement or amendment to any document incorporated
            therein by reference to any person other than a person to whom such
            Underwriter had delivered such incorporated document or documents in
            response to a written request therefor. The foregoing indemnity
            agreement is in addition to any liability which the Company may
            otherwise have to any Underwriters or any controlling person of such
            Underwriter.

                  B. Each Underwriter agrees severally, and not jointly to
            indemnify and hold harmless the Company, each of its directors, each
            of its officers who signed the Registration Statement, and each
            person, if any, who controls the Company within the meaning of
            Section 15 of the Securities Act against any and all loss, claim,
            damage or liability, or any action in respect thereof, to which the
            Company or any such director, officer or controlling person may
            become subject, under the Securities Act or otherwise, insofar as
            such loss, claim, damage, liability or action arises out of, or is
            based upon, (i) any untrue statement or alleged untrue statement of
            a material fact contained in the Registration Statement, (ii) 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, (iii) any untrue statement or alleged untrue
            statement of a material fact contained in the Prospectus or (iv) 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, but in each case only to the extent that the
            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 Company by or on behalf of such
            Underwriter specifically for inclusion therein, and shall reimburse
            the Company and any such director, officer or controlling person for
            any legal or other expenses reasonably incurred by the Company or
            any director, officer or controlling person in connection with
            investigating or defending or preparing to defend against any such
            loss, claim, damage, liability or


                                       24
<PAGE>   25
            action as such expenses are incurred. The foregoing indemnity
            agreement is in addition to any liability which any Underwriter may
            otherwise have to the Company or any such director, officer or
            controlling person.

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

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

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


                                       25
<PAGE>   26
Section VIII consist of the Company or any of the Company's directors, officers
or controlling persons.

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

            Notwithstanding the foregoing sentence, if at any time an
indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel, the indemnifying party
agrees that it shall be liable for any settlement of any proceeding effected
without its written consent if (i) such settlement is entered into more than 30
days after receipt by such indemnifying party of the aforesaid request and (ii)
such indemnifying party shall not have reimbursed the indemnified party in
accordance with such request prior to the date of such settlement.

                  D. Each Underwriter agrees to deliver to the Company no later
            than the date on which the Prospectus Supplement is required to be
            filed pursuant to Rule 424 with a copy of its Derived Information
            (defined below) for filing with the Commission on Form 8-K.

                  E. Each Underwriter agrees, assuming all Company-Provided
            Information (defined below) is accurate and complete in all material
            respects, to severally and not jointly indemnify and hold harmless
            the Company, each of the Company's officers and directors and each
            person who controls the Company within the meaning of Section 15 of
            the Securities Act against any and all losses, claims, damages or
            liabilities, joint or several, to which they may become subject
            under the Securities 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 of a material fact
            contained in the Derived Information provided by such Underwriter,
            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 or preparing to defend any such loss,
            claim, damage, liability or action as such expenses are incurred.
            The obligations of each of the Underwriters under this Section
            VIII(E) shall be in addition to any liability which such Underwriter
            may otherwise have.


                                       26
<PAGE>   27
            The procedures set forth in Section VIII(C) shall be equally
applicable to this Section VIII(E).

                  F. For purposes of this Section VIII, the term "Derived
            Information" means such portion, if any, of the information
            delivered to the Company pursuant to Section VIII(D) for filing with
            the Commission on Form 8-K as:

            (i)   is not contained in the Prospectus without taking into account
                  information incorporated therein by reference;

            (ii)  does not constitute Company-Provided Information; and

            (iii) is of the type of information defined as Collateral term
                  sheets, Structural term sheets or Computational Materials (as
                  such terms are interpreted in the No-Action Letters).

            "Company-Provided Information" means any computer tape furnished to
the Underwriters by the Company concerning the Mortgage Loans comprising the
Trust.

            The terms "Collateral term sheet" and "Structural term sheet" shall
have the respective meanings assigned to them in the February 13, 1995 letter
(the "PSA Letter") of Cleary, Gottlieb, Steen & Hamilton on behalf of the Public
Securities Association (which letter, and the SEC staff's response thereto, were
publicly available February 17, 1995). The term "Collateral term sheet" as used
herein includes any subsequent Collateral term sheet that reflects a substantive
change in the information presented. The term "Computational Materials" has the
meaning assigned to it in the May 17, 1994 letter (the "Kidder letter" and
together with the PSA Letter, the "No-Action Letters") of Brown & Wood on behalf
of Kidder, Peabody & Co., Inc. (which letter, and the SEC staff's response
thereto, were publicly available May 20, 1994).

                  G. If the indemnification provided for in this Section VIII
            shall for any reason be unavailable to or insufficient to hold
            harmless an indemnified party under Section VIII(A) or (B) in
            respect of any loss, claim, damage or liability, or any action in
            respect thereof, referred to therein, then each indemnifying party
            shall, in lieu of indemnifying such indemnified party, contribute to
            the amount paid or payable by such indemnified party as a result of
            such loss, claim, damage or liability, or action in respect thereof,
            (i) in such proportion as shall be appropriate to reflect the
            relative benefits received by the Company on the one hand and the
            Underwriters on the other from the offering of the Offered
            Certificates or (ii) if the allocation provided by clause (i) above
            is not permitted by applicable law or if the indemnified party
            failed to give the notice required under Section VIII(C), 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 Company on the one hand and the Underwriters on the other
            with respect to the statements or omissions which resulted in such


                                       27
<PAGE>   28
            loss, claim, damage or liability, or action in respect thereof, as
            well as any other relevant equitable considerations.

            The relative benefits of the Underwriters and the Company shall be
deemed to be in such proportion so that the Underwriters are responsible for
that portion represented by the percentage that the underwriting discount
appearing on the cover page of the Prospectus bears to the public offering price
appearing on the cover page of the Prospectus.

            The relative fault of the Underwriters and the Company shall be
determined by reference to whether the untrue or alleged untrue statement of a
material fact or omission or alleged omission to state a material fact relates
to information supplied by the Company or by one of the Underwriters, the intent
of the parties and their relative knowledge, access to information and
opportunity to correct or prevent such statement or omission and other equitable
considerations.

            The Company and the Underwriters agree that it would not be just and
equitable if contributions pursuant to this Section VIII(G) were to be
determined by pro rata allocation or by any other method of allocation which
does not take into account the equitable considerations referred to herein. The
amount paid or payable by an indemnified party as a result of the loss, claim,
damage or liability, or action in respect thereof, referred to above in this
Section VIII(G) shall be deemed to include, for purposes of this Section
VIII(G), any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending any such action or claim.

            In no case shall any Underwriter be responsible for any amount in
excess of the underwriting discount applicable to the Certificates purchased by
such Underwriter hereunder. 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.

                  H. The Underwriters severally confirm that the information set
            forth (i) in the Prospectus Supplement relating to market making and
            (ii) in the fourth paragraph under the caption "Underwriting" in the
            Prospectus Supplement, together with the Derived Information, is
            correct and constitutes the only information furnished in writing to
            the Company by or on behalf of the Underwriters specifically for
            inclusion in the Registration Statement and the Prospectus.

            Section IX. Representations, Warranties and Agreements to Survive
Delivery. All representations, warranties and agreements contained in this
Agreement or contained in certificates of officers of the Company submitted
pursuant hereto shall remain operative and in full force and effect, regardless
of any investigation made by or on behalf of the Underwriters or controlling
persons thereof, or by or on behalf of the Company and shall survive delivery of
any Offered Certificates to the Underwriters.


                                       28
<PAGE>   29
            Section X. Termination of Agreement. The Representative may
terminate this Agreement immediately upon notice to the Company, at any time at
or prior to the Closing Date if any of the events or conditions described in
Section VI(W) of this Agreement shall occur and be continuing. In the event of
any such termination, the covenant set forth in Section V(G), the provisions of
Section VII, the indemnity agreement set forth in Section VIII, and the
provisions of Sections IX and XIII shall remain in effect.

            Section XI. Notices. All statements, requests, notices and

            Section XII. Persons Entitled to the Benefit of this Agreement. This
Agreement shall inure to the benefit of and be binding upon the Underwriters and
the Company, and their respective successors. This Agreement and the terms and
provisions hereof are for the sole benefit of only those persons, except that

Company who have signed the Registration Statement and any person controlling
the Company within the meaning of Section 15 of the Securities Act. Nothing in
this Agreement is intended or shall be construed to give any person, other than
the persons referred to in this Section XII, any legal or equitable right,
remedy or claim under or in respect of this Agreement or any provision contained
herein.

            Section XIII. Default by One of the Underwriters. If one of the
Underwriters shall fail on the Closing Date to purchase the Offered Certificates
which it is obligated to purchase hereunder (the "Defaulted Certificates"), the
remaining Underwriters (the "Non-Defaulting Underwriter"), shall have the right,
but not the obligation within one (1) Business Day thereafter, to make
arrangements to purchase all, but not less than all, of the Defaulted
Certificates upon the terms herein set forth; if, however, the Non-Defaulting
Underwriter shall not have completed such arrangements within such one (1)
Business Day period, then this Agreement shall terminate without liability on
the part of the Non-Defaulting Underwriter.

            No action taken pursuant to this Section XIII shall relieve the
defaulting Underwriter from liability in respect of its default.


                                       29
<PAGE>   30
            In the event of any such default which does not result in a
termination of this Agreement, either the Non-Defaulting Underwriter or the
Company shall have the right to postpone the Closing Date for a period not
exceeding seven days in order to effect any required changes in the Registration
Statement or Prospectus or in any other documents or arrangements.

            Section XIV. Survival. The respective indemnities, representations,
warranties and agreements of the Company and the Underwriters contained in this
Agreement, or made by or on behalf of them, respectively, pursuant to this
Agreement, shall survive the delivery of and payment for the Certificates and
shall remain in full force and effect, regardless of any investigation made by
or on behalf of any of them or any person controlling any of them.

            Section XV. Definition of the Term "Business Day". For purposes of
this Agreement, "Business Day" means any day on which the New York Stock
Exchange, Inc. is open for trading.

            Section XVI. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK AND SHALL BE
CONSTRUED IN ACCORDANCE WITH SUCH LAWS WITHOUT REGARD TO PRINCIPLES OF CONFLICTS
OF LAW, SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

            Section XVII. Counterparts. This Agreement may be executed in
counterparts and, if executed in more than one counterpart, the executed
counterparts shall each be deemed to be an original but all such counterparts
shall together constitute one and the same instrument.

            Section XVIII. Headings. The headings herein are inserted for
convenience of reference only and are not intended to be part of, or to affect
the meaning or interpretation of, this Agreement.

            Section XIX. Representations of Underwriters. The Representative

            Re:   Underwriting Agreement dated March __, 1998 (the
                  "Underwriting Agreement") between Advanta Mortgage
                  Conduit Services, Inc. ("Advanta") and Morgan Stanley
                  & Co. Incorporated (the "Representative") and
                  Indemnification Agreement dated as of March ___, 1998
                  (the "Indemnification Agreement") among MBIA
                  Insurance Corporation (the "Insurer"), Advanta and
                  the Representative
                  -------------------------------------------------------

Ladies and Gentlemen:

            Pursuant to the Underwriting Agreement and the Indemnification
Agreement (together, the "Designated Agreements"), Advanta has undertaken
certain financial obligations with respect to the indemnification of the
Underwriters and the Insurer with respect to the Registration Statement, the
Prospectus and the Prospectus Supplement described in the Designated Agreements.
Any financial obligations of Advanta under the Designated Agreements, whether or
not specifically enumerated in this paragraph, are hereinafter referred to as
the "Joint and Several Obligations"; provided, however, the "Joint and Several
Obligations" shall mean only the financial obligations of Advanta under the
Designated Agreements (including the payment of money damages for a breach of
any of Advanta's obligations under the Designated Agreement, whether financial
or otherwise) but shall not include any obligations not relating to the payment
of money.

            As a condition of their respective executions of the Underwriting
Agreement and of the Indemnification Agreement, the Underwriters and the Insurer
have required the undersigned, Advanta Mortgage Holding Company ("AMHC"), the
parent corporation of Advanta, to acknowledge its joint-and-several liability
with Advanta for the payment of the Joint and Several Obligations under the
Designated Agreements.

            Now, therefore, the Underwriters, the Insurer and AMHC do hereby
agree that:
<PAGE>   34
         (i)      AMHC hereby agrees to be absolutely and unconditionally
                  jointly and severally liable with Advanta to the Underwriters
                  for the payment of the Joint and Several Obligations under the
                  Underwriting
                  Agreement.

        (ii)      AMHC hereby agrees to be absolutely and unconditionally

the written approval of the Group I Insurer and the Trustee.

         SECTION 3.3. REPRESENTATIONS AND WARRANTIES OF THE SPONSOR WITH RESPECT
TO THE MORTGAGE LOANS.

         (a) The Sponsor makes the following representations and warranties as
to the Mortgage Loans on which the Group I Insurer relies and the Trustee relies
in accepting the Mortgage Loans in trust and executing and authenticating the
Certificates. Such representations and warranties speak as of the Startup Day
with respect to the Mortgage Loans, or as of the date upon which any Qualified
Replacement Mortgage is added to the Trust, but shall survive the sale,
transfer, and assignment of the Mortgage Loans to the Trustee:


                                       47
<PAGE>   53
         (i) The information with respect to each Mortgage Loan set forth in the
    Schedules of Mortgage Loans is true and correct as of the Cut-Off Date;

         (ii) All of the Notes and other original or certified documentation set
    forth in Section 3.5 (including all material documents related thereto) with
    respect to each Mortgage Loan, except the Mortgage Loans listed on Schedule
    I-a (the "Exception Loans") hereto, has been delivered to the Trustee on the
    Startup Day, or as otherwise provided in Section 3.5. The Sponsor hereby
    covenants to deliver, or cause to be delivered, the File (including the
    original Note) for each Exception Loan to the Trustee on or before April 2,
    1998 or shall repurchase such Exception Loan from the Trust (without regard
    to any cure period) by remitting the Loan Purchase Price therefore to the
    Trustee on or before April 2, 1998;

         (iii)Except for any Unaffiliated Originator Loans being serviced by a
    servicer other than the Master Servicer, each Mortgage Loan is being
    serviced by the Master Servicer or a Person controlling, controlled by or
    under common control with the Master Servicer and qualified to service
    mortgage loans;

         (iv) The Note related to each Mortgage Loan in Group I bears a Coupon
    Rate of at least 6.69% per annum;

         (v) As of the Cut-Off Date, no more than 0.68% of the aggregate Loan
    Balance of the Mortgage Loans are 30-59 days Delinquent and no Mortgage Loan
    is 60 or more days' Delinquent;

         (vi) As of the Cut-Off Date, no more than 1.00% of the aggregate Loan
    Balance of the Mortgage Loans is secured by Properties located within any
    single zip code area and less than 8.58% of the aggregate Loan Balance of
    the Mortgage Loans consists of Date of Payment Loans or "simple interest"
    Mortgage Loans;

         (vii)Each Mortgage Loan conforms, and all such Mortgage Loans in the
    aggregate conform, in all material respects to the description thereof set
    forth in the Registration Statement; and

         (viii) The credit underwriting guidelines applicable to each Mortgage
    Loan conform in all material respects to the description thereof set forth
    in the Prospectus.

         (b) The Sponsor hereby assigns to the Trustee for the benefit of the
Owners of the Certificates and the Group I Insurer (so long as a Group I Insurer
Default had not occurred and is continuing) all of its right, title and interest
in respect of each Master Transfer Agreement applicable to the related Mortgage
Loan. Insofar as such Master Transfer Agreement provides for representations and
warranties made by the related Originator in respect of a Mortgage Loan and any
remedies provided thereunder for any breach of such representations and
warranties, such right, title and interest may be enforced by the Master
Servicer or by the Trustee on behalf of the Owners and the Group I Insurer. Upon
the discovery by the Sponsor, the Master Servicer, the Group I Insurer or the
Trustee of a breach of any of the representations and warranties made in a
Master Transfer Agreement in respect of any Mortgage Loan which materially and
adversely affects the interests of the Owners or of the Group I Insurer in such
Mortgage Loan, the party discovering such breach shall give prompt written
notice to the other parties. The Master Servicer shall promptly notify the
related Originator of such breach and request that such Originator cure such
breach or take the actions described in Section 3.4(b) hereof within the time


                                       48
<PAGE>   54
periods required thereby, and if such Originator does not cure such breach in
all material respects, the Sponsor shall cure such breach or take such actions.
The obligations of the Sponsor or Master Servicer, as the case may be, set forth
herein with respect to any Mortgage Loan as to which such a breach has occurred
and is continuing shall constitute the sole obligations of the Master Servicer
and of the Sponsor in respect of such breach.

         SECTION 3.4. COVENANTS OF SPONSOR TO TAKE CERTAIN ACTIONS WITH RESPECT
TO THE MORTGAGE LOANS IN CERTAIN SITUATIONS.

         (a) With the provisos and limitations as to remedies set forth in this
Section 3.4, upon the discovery by any Originator, the Sponsor, the Master
Servicer, the Group I Insurer, any Sub-Servicer or the Trustee that the
representations and warranties set forth in Section 3.3 of this Agreement or in
the Master Transfer Agreement were untrue in any material respect as of the
Startup Day and such breaches of the representations and warranties materially
and adversely affect the interests of the Owners or of the Group I Insurer, the
party discovering such breach shall give prompt written notice to the other
parties.

         The Sponsor acknowledges that a breach of any representation or
warranty (x) relating to marketability of title sufficient to transfer
unencumbered title to a Mortgage Loan, (y) relating to enforceability of the
Mortgage Loan against the related Mortgagor or Property or (z) set forth in
clause (viii) of Section 3.3 above constitutes breach of a representation or
warranty which "materially and adversely affects the interests of the Owners or
of the Group I Insurer in such Mortgage Loan.

         (b) Upon the earliest to occur of the Sponsor's discovery, its receipt
of notice of breach from any one of the other parties hereto or from the Group I
Insurer or such time as a breach of any representation and warranty materially
and adversely affects the interests of the Owners or of the Group I Insurer as
set forth above, the Sponsor hereby covenants and warrants that it shall
promptly cure such breach in all material respects or it shall (or shall cause
an affiliate of the Sponsor to or an Originator to), subject to the further
requirements of this paragraph, on the second Remittance Date next succeeding
such discovery, receipt of notice or such other time (i) substitute in lieu of
each Mortgage Loan in the related Mortgage Loan Group which has given rise to
the requirement for action by the Sponsor a Qualified Replacement Mortgage and
deliver the Substitution Amount applicable thereto, together with the aggregate
amount of all Delinquency Advances and Servicing Advances theretofore made with
respect to such Mortgage Loan, to the Master Servicer for deposit in the
Principal and Interest Account or (ii) purchase such Mortgage Loan from the
REMIC Trust at a purchase price equal to the Loan Purchase Price thereof, which
purchase price shall be delivered to the Master Servicer for deposit in the
Principal and Interest Account. In connection with any such proposed purchase or
substitution, the Sponsor at its expense, shall cause to be delivered to the
Trustee and the Group I Insurer an opinion of counsel experienced in federal
income tax matters stating whether or not such a proposed purchase or
substitution would constitute a Prohibited Transaction for the REMIC Trust or
would jeopardize the status of the REMIC Trust as a REMIC, and the Sponsor shall
only be required to take either such action to the extent such action would not
constitute a Prohibited Transaction for the REMIC Trust or would not jeopardize
the status of the REMIC Trust as a REMIC. Any required purchase or substitution,
if delayed by the absence of such opinion shall nonetheless occur upon the
earlier of (i) the occurrence of a default or imminent default with respect to
the Mortgage Loan, (ii) the delivery of such opinion or (iii) at the direction
of the Control Party. It is understood and agreed that the obligation of the
Sponsor to cure the defect, or substitute for, or purchase any Mortgage Loan as
to which a representation or warranty is untrue


                                       49
<PAGE>   55
in any material respect and has not been remedied shall constitute the sole
remedy available to the Owners, the Trustee and the Group I Insurer.

         (c) In the event that any Qualified Replacement Mortgage is delivered
by an Originator or by the Sponsor (or by an affiliate of the Sponsor, as the
case may be) to the Trust pursuant to Section 3.3, Section 3.4 or Section 3.6
hereof, the related Originator and the Sponsor shall be obligated to take the
actions described in Section 3.4(b) with respect to such Qualified Replacement
Mortgage upon the discovery by any of the Owners, the Sponsor, the Master
Servicer, the Group I Insurer, any Sub-Servicer or the Trustee that the
representations and warranties set forth in the related Master Transfer
Agreement or in Section 3.3 above are untrue in any material respect on the date
such Qualified Replacement Mortgage is conveyed to the Trust such that the
interests of the Owners or the Group I Insurer in the related Qualified
Replacement Mortgage are materially and adversely affected; provided, however,
that for the purposes of this subsection (c) the representations and warranties
in the related Master Transfer Agreement or as set forth in Section 3.3 above
referring to items "as of the Cut-Off Date" or "as of the Startup Day" shall be
deemed to refer to such items as of the date such Qualified Replacement Mortgage
is conveyed to the Trust.

         (d) It is understood and agreed that the covenants set forth in this
Section 3.4 shall survive delivery of the respective Mortgage Loans (including
Qualified Replacement Mortgage Loans) to the Trustee.

         (e) Notwithstanding anything to the contrary contained herein, the
Sponsor shall deliver, or cause to be delivered, the File (including the
original Note) for each Mortgage Loan to the Trustee on or before April 2, 1998
or shall repurchase such Mortgage Loan from the Trust (without regard to any
cure period) by remitting the Loan Purchase Price on or before April 2, 1998.

         SECTION 3.5. CONVEYANCE OF THE MORTGAGE LOANS.

         (a) The Sponsor and its Affiliate, Advanta Conduit Receivables, Inc.,
concurrently with the execution and delivery hereof, and on behalf of the
Conduit Acquisition Trust, hereby each transfers, sells, assigns, sets over and
otherwise conveys without recourse, to the Trustee, all right, title and
interest of the Conduit Acquisition Trust in and to each Mortgage Loan listed on
the Schedule of Mortgage Loans delivered by the Sponsor on the Startup Day, all
its right, title and interest in and to principal collected and interest
accruing on each such Mortgage Loan on and after the Cut-Off Date and all its
right, title and interest in and to all Insurance Policies and any other assets
included or to be included in the Trust for the benefit of Owners and the Group
I Insurer. The transfer by the Conduit Acquisition Trust of the Initial Mortgage
Loans set forth on the Schedule of Initial Mortgage Loans to the Trustee is
absolute and is intended by the Owners and all parties hereto to be treated as a
sale by the Conduit Acquisition Trust.

         (b) The Sponsor agrees to take or cause to be taken such actions and
execute such documents (including, without limitation, the filing of all
necessary continuation statements for the UCC-1 financing statements filed in
the State of New York (which shall have been filed within 90 days of the Startup
Day) describing the Mortgage Loans and naming the Conduit Acquisition Trust as
debtor and the Trustee as the secured party and any amendments to UCC-1
financing statements required to reflect a change in the name or corporate
structure of the debtor or the filing of any additional UCC-1 financing
statements due to a change in the principal officer of the debtor (within 90
days of any event necessitating such filing) as are necessary to perfect


                                       50
<PAGE>   56
and protect the Owners' and the Group I Insurer's interests in each Mortgage
Loan and the proceeds thereof.

         (c) In connection with the transfer and assignment of the Mortgage
Loans, the Sponsor agrees to:

         (i) cause to be delivered, on the Startup Day, without recourse, to the
    Trustee the items listed in the definitions of "Advanta Mortgage Files" and
    "Conduit Mortgage Files," as appropriate; provided that the assignments of
    mortgage listed in clause (e) of Exhibit B hereto shall be delivered to the
    Trustee within 75 Business Days of the Startup Day.

         (ii) cause, within 75 Business Days following the Startup Day the
    assignments of Mortgage to be submitted for recording in the appropriate
    jurisdictions wherein such recordation is necessary to perfect the lien
    thereof as against creditors of or purchasers from the related Originator to
    the Trustee; provided, however, that, for administrative convenience and
    facilitation of servicing and to reduce closing costs, assignments of
    mortgage shall not be required to be submitted for recording with respect to
    any Mortgage Loan which relates to an Advanta Mortgage File only if the
    Trustee, the Group I Insurer and each Rating Agency has received an Opinion
    of Counsel, satisfactory in form and substance to the Group I Insurer and to
    each Rating Agency, to the effect that the recordation of such assignments
    in any specific jurisdiction is not necessary to protect the Trustee's
    interest in the related Mortgage.

         All recording required pursuant to this Section 3.5 shall be
accomplished at the expense of the Originators or of the Sponsor.
Notwithstanding anything to the contrary contained in this Section 3.5, in those
instances where the public recording office retains the original Mortgage, the
assignment of a Mortgage or the intervening assignments of the Mortgage after it
has been recorded, the Sponsor shall be deemed to have satisfied its obligations
hereunder upon delivery to the Trustee of a copy of such Mortgage, such
assignment or assignments of Mortgage certified by the public recording office
to be a true copy of the recorded original thereof.

         Copies of all Mortgage assignments received by the Trustee shall be
kept in the related file.

         Such assignments of mortgage shall, in addition to the requirements
specified in Exhibit B, be in recordable form. On or before the Startup Day, the
Sponsor shall deliver to the Trustee original executed powers of attorney, from
the current recordholders of the related Mortgage substantially in the form of
Exhibit H, authorizing the Master Servicer on behalf of the Trustee to record
the assignments of mortgage as provided in clause (ii) above. Pursuant to such
power of attorney, the Trustee also may execute a new assignment of mortgage for
any Mortgage Loan if the original assignment of mortgage delivered by the
Sponsor to the Trustee is not in recordable form at such time as the assignment
of mortgage is to be recorded by the Trustee.

         (d) In the case of Mortgage Loans which have been prepaid in full on or
after the Cut-Off Date and prior to the Startup Day, the Sponsor, in lieu of the
foregoing, will deliver within 15 Business Days after the Startup Day, to the
Trustee a certification of an Authorized Officer in the form set forth in
Exhibit C.

         (e) The Sponsor (or the Conduit Acquisition Trust or an affiliate of
the Sponsor) shall transfer, sell, assign, set over and otherwise convey without
recourse, to the


                                       51
<PAGE>   57
Trustee all right, title and interest of the Sponsor (or the Conduit Acquisition
Trust or of such affiliate) in and to any Qualified Replacement Mortgage
delivered to the Trustee pursuant to Section 3.3, Section 3.4 or Section 3.6
hereof and all its right, title and interest to principal collected and interest
accruing on such Qualified Replacement Mortgage on and after the applicable
Replacement Cut-Off Date; provided, however, that the Sponsor (or the Conduit
Acquisition or such affiliate) shall reserve and retain all right, title and
interest in and to payments of principal and interest due on such Qualified
Replacement Mortgage prior to the applicable Replacement Cut-Off Date.

         (f) As to each Mortgage Loan released from the Trust in connection with
the conveyance of a Qualified Replacement Mortgage therefor, the Trustee will
transfer, sell, assign, set over and otherwise convey without recourse, on the
Sponsor's order, all of its right, title and interest in and to such released
Mortgage Loan and all the Trust's right, title and interest to principal
collected and interest accruing on such released Mortgage Loan on and after the
applicable Replacement Cut-Off Date; provided, however, that the Trust shall
reserve and retain all right, title and interest in and to payments of principal
collected and interest accruing on such released Mortgage Loan prior to the
applicable Replacement Cut-Off Date.

         (g) In connection with any transfer and assignment of a Qualified
Replacement Mortgage to the Trustee on behalf of the Trust, the Sponsor agrees
to cause to be delivered to the Trustee the items described in Section 3.5(b) on
the date of such transfer and assignment or, if a later delivery time is
permitted by Section 3.5(b), then no later than such later delivery time.

         (h) As to each Mortgage Loan released from the Trust in connection with
the conveyance of a Qualified Replacement Mortgage the Trustee shall deliver on
the date of conveyance of such Qualified Replacement Mortgage and on the order
of the Sponsor (i) the original Note, or the certified copy, relating thereto,
endorsed without recourse, to the Sponsor and (ii) such other documents as
constituted the File with respect thereto.

         (i) If a Mortgage assignment is lost during the process of recording,
or is returned from the recorder's office unrecorded due to a defect therein,
the Sponsor shall prepare a substitute assignment or cure such defect, as the
case may be, and thereafter cause each such assignment to be duly recorded.

         (j) The Sponsor shall cause to be reflected on the records of the
Conduit Acquisition Trust that the Mortgage Loans have been sold to the Trust.

         (k) To the extent that the ratings, if any, then assigned to the
unsecured debt of the Sponsor or of the Sponsor's ultimate corporate parent are
satisfactory to the Control Party and each of the Rating Agencies, then any of
the Document Delivery Requirements described above may be waived by an
instrument signed by the Control Party and each of the Rating Agencies (or any
documents theretofore delivered to the Trustee returned to the Sponsor) on such
terms and subject to such conditions as the Control Party, and each of the
Rating Agencies may permit.

         SECTION 3.6. ACCEPTANCE BY TRUSTEE; CERTAIN SUBSTITUTIONS OF MORTGAGE
LOANS; CERTIFICATION BY TRUSTEE.

         (a) The Trustee agrees to execute and deliver on the Startup Day an
acknowledgment of receipt in the form attached as Exhibit D hereto of the Files
delivered by the


                                       52
<PAGE>   58
Sponsor, and declares that it will hold such documents and any amendments,
replacement or supplements thereto, as well as any other assets included in the
definition of Trust Estate and delivered to the Trustee, as Trustee in trust
upon and subject to the conditions set forth herein for the benefit of the
Owners and the Group I Insurer. On or before the tenth Business Day after the
Startup Day, the Trustee shall execute and deliver to the Group I Insurer and
the Master Servicer an acknowledgement of receipt of the original Notes for each
Mortgage Loan. The Trustee further agrees to review any documents delivered by
the Sponsor within 90 days after the Startup Day (or within 90 days with respect
to any Qualified Replacement Mortgage after the assignment thereof) and to
deliver to the Sponsor, the Group I Insurer and the Master Servicer a
Certification in the form attached as Exhibit E hereto. 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, nor shall the Trustee be under any
duty to determine independently whether there are any intervening assignments or
assumption or modification agreements with respect to any Mortgage Loan.

         (b) If the Trustee during such 90-day period finds any document
constituting a part of a File which is not properly executed, has not been
received within the specified period, or is unrelated to the Mortgage Loans
identified in the Schedules of Mortgage Loans, or that any Mortgage Loan does
not conform in a material respect to the description thereof as set forth in the
Schedules of Mortgage Loans, the Trustee shall promptly so notify the Sponsor
and the Group I Insurer. In performing any such review, the Trustee may
conclusively rely on the Sponsor as to the purported genuineness of any such
document and any signature thereon. The Sponsor agrees to use reasonable efforts
to remedy a material defect in a document constituting part of a 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 Sponsor has not remedied or
caused to be remedied the defect and the defect materially and adversely affects
the interest in the related Mortgage Loan of the Owners or of the Group I
Insurer, the Sponsor will (or will cause the related Originator or an affiliate
of the Sponsor to) on the next succeeding Remittance Date (i) substitute in lieu
of such Mortgage Loan a Qualified Replacement Mortgage and, deliver the
Substitution Amount applicable thereto to the Master Servicer for deposit in the
Principal and Interest Account or (ii) purchase such Mortgage Loan at a purchase
price equal to the Loan Purchase Price thereof, which purchase price shall be
delivered to the Master Servicer for deposit in the Principal and Interest
Account. In connection with any such proposed purchase or substitution the
Sponsor shall cause at the Sponsor's expense to be delivered to the Trustee and
the Group I Insurer an opinion of counsel experienced in federal income tax
matters stating whether or not such a proposed purchase or substitution would
constitute a Prohibited Transaction for the Upper-Tier REMIC or Lower-Tier REMIC
or would jeopardize the status of the Upper-Tier REMIC or Lower-Tier REMIC as a
REMIC, and the Sponsor shall only be required to take either such action to the
extent such action would not constitute a Prohibited Transaction for the
Upper-Tier REMIC or Lower-Tier REMIC or would not jeopardize the status of the
Upper-Tier REMIC or Lower-Tier REMIC as a REMIC. Any required purchase or
substitution, if delayed by the absence of such opinion shall nonetheless occur
upon the earlier of (i) the occurrence of a default or imminent default with
respect to the Mortgage Loan or (ii) the delivery of such opinion or (iii) at
the direction of the Control Party.

         SECTION 3.7. COOPERATION PROCEDURES.

         (a) The Sponsor shall, in connection with the delivery of each
Qualified Replacement Mortgage to the Trustee, provide the Trustee with the
information set forth in the Schedules of Mortgage Loans with respect to such
Qualified Replacement Mortgage.


                                       53
<PAGE>   59
         (b) The Sponsor, the Master Servicer and the Trustee covenant to
provide each other and to the Group I Insurer with all data and information
required to be provided by them hereunder at the times required hereunder, and
additionally covenant reasonably to cooperate with each other in providing any
additional information required by any of them in connection with their
respective duties hereunder.

                     CERTIFICATES AND TRANSFER OF INTERESTS

         SECTION 5.1. TERMS.

         (a) The Certificates are pass-through securities having the rights
described therein and herein. Notwithstanding references herein or therein with
respect to the Certificates as to "principal" and "interest" no debt of any
Person is represented thereby, nor are the Certificates or the underlying Notes
guaranteed by any Person (except that the Notes may be recourse to the
Mortgagors thereof to the extent permitted by law and except for the rights of
the Trustee with respect to the Group I Insurance Policy). Distributions on the
Certificates are payable solely from payments received on or with respect to the
Mortgage Loans (other than the Servicing Fees), monies in the Principal and
Interest Account, and the Supplemental Interest Payment Account, except as
otherwise provided herein, from earnings on monies and the proceeds of property
held as a part of the Trust Estate and, with respect to the Group I Certificates
upon the occurrence of certain events, from Group I Insured Payments. Each
Certificate entitles the Owner thereof to receive monthly, on each Payment Date,
in order of priority of distributions with respect to such Class of
Certificates, a specified portion of such payments with respect to the Mortgage
Loans in the related Mortgage Loan Group and (i) with respect to the Group I


                                       54
<PAGE>   60
Certificates, the Group I Insured Payments, pro rata in accordance with such
Owner's Percentage Interest and (ii) certain amounts payable from the
Supplemental Interest Payment Account.

         (b) Each Owner is required, and hereby agrees, to return to the Trustee
any Certificate with respect to which the Trustee has made the final
distribution due thereon. Any such Certificate as to which the Trustee has made
the final distribution thereon shall be deemed cancelled and shall no longer be
Outstanding for any purpose of this Agreement, whether or not such Certificate
is ever returned to the Trustee.

          SECTION 5.2. FORMS. The Certificates shall be in substantially the
forms set forth in Exhibit A hereof with such appropriate insertions, omissions,
substitutions and other variations as are required or permitted by this
Agreement or as may in the Sponsor's judgment be necessary, appropriate or
convenient to comply, or facilitate compliance, with applicable laws, and may
have such letters, numbers or other marks of identification and such legends or
endorsements placed thereon as may be required to comply with the rules of any
applicable securities laws or as may, consistently herewith, be determined by
the Authorized Officer of the Sponsor executing such Delivery Order, as
evidenced by his execution thereof.

         SECTION 5.3. EXECUTION, AUTHENTICATION AND DELIVERY. Each Certificate
shall be executed on behalf of the Trust, by the manual signature of one of the
Trustee's Authorized Officers and shall be authenticated by the manual signature
of one of the Trustee's Authorized Officers.

         (a) Certificates bearing the manual signature of individuals who were
at any time the proper officers of the Trustee shall, upon proper authentication
by the Trustee, bind the Trust, notwithstanding that such individuals or any of
them have ceased to hold such offices prior to the execution and delivery of
such Certificates or did not hold such offices at the date of authentication of
such Certificates.

         (b) The initial Certificates shall be dated as of the Startup Day and
delivered at the Closing to the parties specified in Section 4.2 hereof.

         (c) No Certificate shall be valid until executed and authenticated as
set forth above.

         SECTION 5.4. REGISTRATION AND TRANSFER OF CERTIFICATES.

         (a) The Trustee, as registrar, shall cause to be kept a register (the
"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 Certificates and transfers of
Certificates as herein provided. The Owners and the Group I Insurer shall have
the right to inspect the Register at all reasonable times and to obtain copies
thereof.

         (b) Subject to the provisions of Section 5.8 hereof, upon surrender for
registration of transfer of any Certificate at the office designated as the
location of the Register, the Trustee shall execute, authenticate and deliver,
in the name of the designated transferee or transferees, one or more new
Certificates of a like Class and in the aggregate principal amount of the
Certificate so surrendered.


                                       55
<PAGE>   61
         (c) At the option of any Owner, Certificates of any Class owned by such
Owner may be exchanged for other Certificates authorized of like Class, tenor
and a like aggregate original principal amount and bearing numbers not
contemporaneously outstanding, upon surrender of the Certificates to be
exchanged at the office designated as the location of the Register. Whenever any
Certificate is so surrendered for exchange, the Trustee shall execute,
authenticate and deliver the Certificate or Certificates which the Owner making
the exchange is entitled to receive.

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

         (e) Any 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
Owner thereof or his attorney duly authorized in writing.

         (f) No service charge shall be made to an Owner 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; any
other expenses in connection with such transfer or exchange shall be an expense
of the Trust.

         (g) It is intended that the Offered Certificates be registered so as to
participate in a global book-entry system with the Depository, as set forth
herein. Each Class of Offered Certificates shall, except as otherwise provided
in the next paragraph, be initially issued in the form of a single fully
registered Offered Certificate with a denomination equal to the Aggregate
Certificate Principal Balance. Upon initial issuance, the ownership of each such
Offered Certificate shall be registered in the Register in the name of Cede &
Co., or any successor thereto, as nominee for the Depository.

         The Sponsor and the Trustee are hereby authorized to execute and
deliver the Representation Letter with the Depository.

         With respect to Offered Certificates registered in the Register in the
name of Cede & Co., as nominee of the Depository, the Sponsor, the Master
Servicer, the Group I Insurer and the Trustee shall have no responsibility or
obligation to Direct or Indirect Participants or beneficial owners for which the
Depository holds Offered Certificates from time to time as a Depository. Without
limiting the immediately preceding sentence, the Sponsor, the Master Servicer,
the Group I Insurer and the Trustee 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 the ownership interest in
the Offered Certificates, (ii) the delivery to any Direct or Indirect
Participant or any other Person, other than a registered Owner of a Offered
Certificate as shown in the Register, of any notice with respect to the Offered
Certificates or (iii) the payment to any Direct or Indirect Participant or any
other Person, other than a registered Owner of a Offered Certificate as shown in
the Register, of any amount with respect to any distribution of principal or
interest on the Offered Certificates. No Person other than a registered Owner of
a Offered Certificate as shown in the Register shall receive a certificate
evidencing such Offered Certificate.


                                       56
<PAGE>   62
         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 registered Owners of
Offered Certificates appearing as registered Owners in the registration books
maintained by the Trustee 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.

         (h) In the event that (i) the Depository or the Sponsor advises the
Trustee and the Group I 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 Offered Certificates and the Sponsor or the
Trustee is unable to locate a qualified successor or (ii) the Sponsor at its
sole option elects to terminate the book-entry system through the Depository,
the Offered Certificates shall no longer be restricted to being registered in
the Register in the name of Cede & Co. (or a successor nominee) as nominee of
the Depository. At that time, the Sponsor may determine that the Offered
Certificates shall be registered in the name of and deposited with a successor
depository operating a global book-entry system, as may be acceptable to the
Sponsor, or such depository's agent or designee but, if the Sponsor does not
select such alternative global book-entry system, then the Offered Certificates
may be registered in whatever name or names registered Owners of Offered
Certificates transferring Offered Certificates shall designate, in accordance
with the provisions hereof; provided, that the cost of any such re-registration
shall be paid by the Sponsor.

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

         (j) Neither the Sponsor, the Master Servicer, the Group I Insurer, nor
the Trustee will have any liability for any actions taken by DTC or its nominee,
Euroclear or CEDEL, including, without limitation, actions for any aspect of the
records relating to or payments made on account of beneficial ownership
interests in the Offered Certificates held by Euroclear, CEDEL or Cede & Co., as
nominee for DTC, or for maintaining supervising or reviewing any records
relating to such beneficial ownership interests.

         SECTION 5.5. MUTILATED, DESTROYED, LOST OR STOLEN CERTIFICATES. If (i)
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 (ii) in the case of any mutilated Certificate, such mutilated
Certificate shall first be surrendered to the Trustee, and in the case of any
destroyed, lost or stolen Certificate, there shall be first delivered to the
Trustee such security or indemnity as may be reasonably required by it to hold
the Trustee harmless (provided, that with respect to an Owner which is an
insurance company, a letter of indemnity furnished by it shall be sufficient for
this purpose; provided, that such insurance company possesses at least an
investment grade rating from any of the Rating Agencies), then, in the absence
of notice to 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 Class, tenor and aggregate principal amount, bearing a
number not contemporaneously outstanding.

         Upon the issuance of any new Certificate under this Section, the
Trustee may require the payment of a sum sufficient to cover any tax or other
governmental charge that may


                                       57
<PAGE>   63
be imposed in relation thereto; any other expenses in connection with such
issuance shall be an expense of the Trust.

         Every new Certificate issued pursuant to this Section in exchange for
or in lieu of any mutilated, destroyed, lost or stolen Certificate shall
constitute evidence of a substitute interest in the Trust, and shall be entitled
to all the benefits of this Agreement equally and proportionately with any and
all other Certificates of the same Class duly issued hereunder and such
mutilated, destroyed, lost or stolen Certificate shall not be valid for any
purpose.

         The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Certificates.

         SECTION 5.6. PERSONS DEEMED OWNERS. The Trustee and any agent of the
Trustee may treat the Person in whose name any Certificate is registered as the
Owner of such Certificate for the purpose of receiving distributions with
respect to such Certificate and for all other purposes whatsoever, and neither
the Trustee nor any agent of the Trustee shall be affected by notice to the
contrary.

         SECTION 5.7. CANCELLATION. All Certificates surrendered for
registration of transfer or exchange shall, if surrendered to any Person other
than the Trustee, be delivered to the Trustee and shall be promptly cancelled by
it. No Certificate shall be authenticated in lieu of or in exchange for any
Certificate cancelled as provided in this Section, except as expressly permitted
by this Agreement. All cancelled Certificates may be held by the Trustee in
accordance with its standard retention policy.

         SECTION 5.8. LIMITATION ON TRANSFER OF OWNERSHIP RIGHTS.

         (a) No sale or other transfer of any Offered Certificate shall be made
to the Sponsor, any Originator or any of their respective affiliates.

         (b) No sale or other transfer of record or beneficial ownership of a
Class R Certificate or assignment of an interest in the Lower-Tier REMIC
Residual Class (whether pursuant to a purchase, a transfer resulting from a
default under a secured lending agreement or otherwise) shall be made to a
Disqualified Organization or an agent of a Disqualified Organization. The
transfer, sale or other disposition of a Class R Certificate or assignment of an
interest in the Lower-Tier REMIC Residual Class (whether pursuant to a purchase,
a transfer resulting from a default under a secured lending agreement or
otherwise) to a Disqualified Organization shall be deemed to be of no legal
force or effect whatsoever and such transferee shall not be deemed to be an
Owner for any purpose hereunder, including, but not limited to, the receipt of
distributions on such Class R Certificate or Lower-Tier REMIC Residual Class.
Furthermore, in no event shall the Trustee accept surrender for transfer,
registration of transfer, or register the transfer, of any Class R Certificate
nor authenticate and make available any new Class R Certificate unless the
Trustee has received an affidavit from the proposed transferee in the form
attached hereto as Exhibit I. Each holder of a Class R Certificate by his
acceptance thereof, shall be deemed for all purposes to have consented to the
provisions of this Section 5.08(b). The Lower-Tier REMIC Residual Class is not
transferable except that the Owner of the Tax Matters Person Residual Interest
in the Lower-Tier REMIC may assign its interest to another Person who accepts
such assignment and the designation as Tax Matters Person pursuant to Section
11.17 hereof.


                                       58
<PAGE>   64
         (c) No other sale or other transfer of record or beneficial ownership
of a Class R Certificate shall be made unless such transfer is exempt from the
registration requirements of the Securities Act of 1933, as amended, and any
applicable state securities laws or is made in accordance with said Act and
laws. In the event such a transfer is to be made within three years from the
Startup Day, (i) the Trustee or the Sponsor shall require a written opinion of
counsel acceptable to and in form and substance satisfactory to the Sponsor that
such transfer may be made pursuant to an exemption, describing the applicable
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 or the Sponsor, and (ii) the Trustee shall require the Transferee
to execute an investment letter acceptable to and in form and substance
satisfactory to the Sponsor certifying to the Trustee and the Sponsor the facts
surrounding such transfer, which investment letter shall not be an expense of
the Trustee or the Sponsor. The Owner of a Class R Certificate desiring to
effect such transfer shall, and does hereby agree to, indemnify the Trustee and
the Sponsor against any liability that may result if the transfer is not so
exempt or is not made in accordance with such federal and state laws. No Class R
Certificate shall be acquired by or transferred to (i) an employee benefit plan
(as defined in section 3(3) of the Employee Retirement Security Act of 1974, as
amended ("ERISA")) subject to the provisions of Title I of ERISA, (ii) a plan
(as defined in Section 4975(e)(1) of the Code) subject to Section 4975 of the
Code, or (iii) an entity whose underlying assets are deemed to be assets of a
plan described in (i) or (ii) above by reason of such plan's investment in the
entity (each, a "Benefit Plan Entity"). Any transferee of a Class R Certificate
shall (x) certify that it is not any of the above and (y) deliver an opinion of
counsel to that effect.

         (d) No Subordinate Certificate shall be acquired by or transferred to a
Benefit Plan Entity other than an insurance company using the assets of its
general account under circumstances whereby the exemptive relief granted in
Prohibited Transaction Exemption 95-60, 60 Fed. Reg. 35925 (July 12, 1995) ("PTE
95-60") is available with respect to the purchase and holding of such
Subordinate Certificate. Each transferee of a Subordinate Certificate shall
represent (or, in the case of any transfer of beneficial ownership in a
book-entry certificate, shall be deemed to represent) that either (i) it is not
a Benefit Plan Entity or (ii) it is an insurance company using the assets of its
general account and that the exemptive relief granted in PTE 95-60 is available
with respect to the transferee's purchase and holding of the Subordinate
Certificate.

         SECTION 5.9. ASSIGNMENT OF RIGHTS. An Owner may pledge, encumber,
hypothecate or assign all or any part of its right to receive distributions
hereunder, but such pledge, encumbrance, hypothecation or assignment shall not
constitute a transfer of an ownership interest sufficient to render the
transferee an Owner of the Trust without compliance with the provisions of
Section 5.4 and Section 5.8 hereof.

                                   ARTICLE VI

                                    COVENANTS

         SECTION 6.1. DISTRIBUTIONS. The Trustee will duly and punctually pay
distributions with respect to the Certificates in accordance with the terms of
the Certificates and this Agreement. Such distributions shall be made (i) by
check mailed on each Payment Date or (ii) if requested by any Owner, to such
Owner by wire transfer to an account within the United States designated no
later than five Business Days prior to the related Record Date, made on each
Payment Date, in each case to each Owner of record on the immediately preceding
Record Date;


                                       59
<PAGE>   65
provided, however, that an Owner of a Offered Certificate shall only be entitled
to payment by wire transfer if such Owner owns Offered Certificates in the
aggregate denomination of at least $5,000,000.

         SECTION 6.2. MONEY FOR DISTRIBUTIONS TO BE HELD IN TRUST; WITHHOLDING.

         (a) All payments of amounts due and payable with respect to any
Certificate that are to be made from amounts withdrawn from the Certificate
Account pursuant to Section 7.5 hereof or, with respect to the Group I
Certificates, from Group I Insured Payments shall be made by and on behalf of
the Trustee, and no amounts so withdrawn from the Certificate Account for
payments of the Certificates and no Group I Insured Payment shall be paid over
to the Trustee except as provided in this Section.

         (b) The Trustee on behalf of the Trust shall comply with all
requirements of the Code and applicable state and local law with respect to the
withholding from any distributions made by it to any Owner of any applicable
withholding taxes imposed thereon and with respect to any applicable reporting
requirements in connection therewith.

         (c) Any money held by the Trustee in trust for the payment of any
amount due with respect to any Offered Certificate and remaining unclaimed by
the Owner of such Offered Certificate for the period then specified in the
escheat laws of the State of New York after such amount has become due and
payable shall be discharged from such trust and be paid first, to the Group I
Insurer on account of any Group I Reimbursement Amount, and second to the Owners
of the Class R Certificates; and the Owner of such Offered Certificate shall
thereafter, as an unsecured general creditor, look only to the Owners of the
Class R Certificates, or in the case of the Group I Certificates, the Group I
Insurer for payment thereof (but only to the extent of the amounts so paid to
the Group I Insurer or the Owners of the Class R Certificates), and all
liability of the Trustee with respect to such trust money shall thereupon cease;
provided, however, that the Trustee, before being required to make any such
payment, shall at the expense of the Sponsor cause to be published once, in the
eastern edition of The Wall Street Journal, notice that such money remains
unclaimed and that, after a date specified therein, which shall be not fewer
than 30 days from the date of such publication, any unclaimed balance of such
money then remaining will be paid to the Group I Insurer or the Owners of the
Class R Certificates as provided above. The Trustee shall, at the direction of
the Sponsor, also adopt and employ, at the expense of the Sponsor, any other
reasonable means of notification of such payment (including but not limited to
mailing notice of such payment to Owners whose right to or interest in monies
due and payable but not claimed is determinable from the Register at the last
address of record for each such Owner).

         SECTION 6.3. PROTECTION OF TRUST ESTATE.

         (a) The Trustee will hold the Trust Estate in trust for the benefit of
the Owners and the Group I Insurer as their interests may appear, and, upon
request of the Group I Insurer, or with the consent of the Group I Insurer, at
the request and expense of the Sponsor, will from time to time execute and
deliver all such supplements and amendments hereto pursuant to Section 11.14
hereof and all instruments of further assurance and other instruments, and will
take such other action upon such request as it deems reasonably necessary or
advisable, to:

         (i) more effectively hold in trust all or any portion of the Trust
    Estate;


                                       60
<PAGE>   66
         (ii) perfect, publish notice of, or protect the validity of any grant
    made or to be made by this Agreement;

         (iii)enforce any of the Mortgage Loans; or

         (iv) preserve and defend title to the Trust Estate and the rights of
    the Trustee, and the ownership interests of the Owners represented thereby,
    in such Trust Estate against the claims of all Persons and parties.

         The Trustee shall send copies of any request received from the Group I
Insurer or the Sponsor to take any action pursuant to this Section 6.3 to the
other party.

         (b) The Trustee shall have the power to enforce, and shall enforce the
obligations of the other parties to this Agreement and of the Group I Insurer by
action, suit or proceeding at law or equity, and shall also have the power to
enjoin, by action or suit in equity, any acts or occurrences which may be
unlawful or in violation of the rights of the Owners; provided, however, that
nothing in this Section shall require any action by the Trustee unless the
Trustee shall first (i) have been furnished indemnity satisfactory to it and
(ii) when required by this Agreement, have been requested to take such action by
a majority of the Percentage Interests represented by the affected Class or
Classes of Offered Certificates then Outstanding or, if there are no longer any
affected Offered Certificates then outstanding, by such majority of the
Percentage Interests represented by the Class R Certificates.

         (c) The Trustee shall execute any instrument required pursuant to this
Section so long as such instrument does not conflict with this Agreement or with
the Trustee's fiduciary duties.

         SECTION 6.4. PERFORMANCE OF OBLIGATIONS.

         (a) The Trustee will not take any action that would release the Sponsor
or the Group I Insurer from any of their respective covenants or obligations
under any instrument or document relating to the Trust Estate or the
Certificates or which would result in the amendment, hypothecation,
subordination, termination or discharge of, or impair the validity or
effectiveness of, any such instrument or document, except as expressly provided
in this Agreement or such other instrument or document.

         The Trustee may contract with other Persons to assist it in performing
its duties hereunder.

         SECTION 6.5. NEGATIVE COVENANTS. The Trustee will not, to the extent
within the control of the Trustee, take any of the following actions:

         (i) sell, transfer, exchange or otherwise dispose of any of the Trust
    Estate except as expressly permitted by this Agreement;

         (ii) claim any credit on or make any deduction from the distributions
    payable in respect of, the Certificates (other than amounts properly
    withheld from such payments under the Code) or assert any claim against any
    present or former Owner by reason of the payment of any taxes levied or
    assessed upon any of the Trust Estate;


                                       61
<PAGE>   67
         (iii)incur, assume or guaranty on behalf of the Trust any indebtedness
    of any Person except pursuant to this Agreement;

         (iv) dissolve or liquidate the Trust Estate in whole or in part, except
    pursuant to Article IX hereof; or

         (v) (A) impair the validity or effectiveness of this Agreement, or
    release any Person from any covenants or obligations with respect to the
    Trust or to the Certificates under this Agreement, except as may be
    expressly permitted hereby or (B) create or extend any lien, charge, adverse
    claim, security interest, mortgage or other encumbrance to or upon the Trust
    Estate or any part thereof or any interest therein or the proceeds thereof.

         SECTION 6.6. NO OTHER POWERS. The Trustee will not, to the extent
within the control of the Trustee, permit the Trust to engage in any business
activity or transaction other than those activities permitted by Section 2.3
hereof.

         SECTION 6.7. LIMITATION OF SUITS. No Owner shall have any right to
institute any proceeding, judicial or otherwise, with respect to this Agreement
or the Group I Insurance Policy or for the appointment of a receiver or trustee,
or for any other remedy hereunder, unless:

                  (A) the Owners of not less than 25% of the Percentage
         Interests represented by the affected Class or Classes of Certificates
         then Outstanding or, if there are no affected Classes of Offered
         Certificates then Outstanding, by such percentage of the Percentage
         Interests represented by the Class R Certificates, shall have made
         written request to the Trustee to institute such proceeding in respect
         of such Event of Default;

                  (B) such Owner or Owners have offered to the Trustee
         reasonable indemnity against the costs, expenses and liabilities to be
         incurred in compliance with such request;

                  (C) the Trustee for 60 days after its receipt of such notice,
         request and offer of indemnity has failed to institute such proceeding;

                  (D) as long as any Group I Certificates, or any Group I
         Reimbursement Amount are outstanding, the Group I Insurer consented in
         writing thereto; and

                  (E) no direction inconsistent with such written request has
         been given to the Trustee during such 60-day period by the Group I
         Insurer or by the Owners of a majority of the Percentage Interests
         represented by the Offered Certificates or, if there are no Offered
         Certificates then Outstanding, by such majority of the Percentage
         Interests represented by the Class R Certificates;

it being understood and intended that no one or more Owners shall have any right
in any manner whatever by virtue of, or by availing themselves of, any provision
of this Agreement to affect, disturb or prejudice the rights of any other Owner
of the same Class or to obtain or to seek to obtain priority or preference over
any other Owner of the same Class or to enforce any right under this Agreement,
except in the manner herein provided and for the equal and ratable benefit of
all the Owners of the same Class.


                                       62
<PAGE>   68
In the event the Trustee shall receive conflicting or inconsistent requests and
indemnity from two or more groups of Owners, each representing less than a
majority of the applicable Class of Certificates, the Trustee shall act at the
direction of the Group I Insurer, notwithstanding any other provision of this
Agreement.

such Certificate or to institute suit for the enforcement of any such
distribution, and such right shall not be impaired without the consent of such
Owner.

         SECTION 6.9. RIGHTS AND REMEDIES CUMULATIVE. Except as otherwise
provided herein, no right or remedy herein conferred upon or reserved to the

other right or remedy, and every right and remedy shall, to the extent permitted
by law, be cumulative and in addition to every other right and remedy given
hereunder or now or hereafter existing at law or in equity or otherwise. Except
as otherwise provided herein, the assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

         SECTION 6.10. DELAY OR OMISSION NOT WAIVER. No delay of the Trustee,
the Group I Insurer or any Owner of any Certificate to exercise any right or
remedy under this Agreement to any Event of Default shall impair any such right

Trustee, the Group I Insurer or to the Owners may be exercised from time to

Insurer or by the Owners, as the case may be.

         SECTION 6.11. CONTROL BY OWNERS. The Group I Insurer (so long as a
Group I Insurer Default has not occurred and is continuing) or the Owners of a

then Outstanding, with the consent of the Control Party (which may not be
unreasonably withheld) or, if there are no longer any Offered Certificates then

Control Party with respect to the Certificates or the Trust Estate, including,
but not limited to, those powers set forth in Section 6.3 and Section 8.20

                  (A) such direction shall not be in conflict with any rule of
         law or with this Agreement;

                  (B) the Control Party shall have been provided with indemnity
         satisfactory to it; and

                  (C) the Trustee may take any other action deemed proper by the
         Trustee, which is not inconsistent with such direction; provided,
         however, that the Trustee need not take any action which it determines
         might involve it in liability or may be unjustly prejudicial to the
         Owners not so directing; provided, further, that in the event that any
         directions provided by the Trustee and the


                                       63

         Group I Insurer conflict with each other, the Group I Insurer's
         direction shall prevail.

continuing, the Group I Insurer shall act as the Control Party until all Group I
Reimbursement Amounts have been paid.

                      ACCOUNTS, DISBURSEMENTS AND RELEASES

         SECTION 7.1. 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 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 Master Servicer or by any Sub-Servicer. The
Trustee shall hold all such money and property received by it, other than
pursuant to or as contemplated by Section 6.2(b) hereof, as part of the Trust
Estate and shall apply it as provided in this Agreement.

         SECTION 7.2. ESTABLISHMENT OF CERTIFICATE ACCOUNT. The Sponsor shall
cause to be established, and the Trustee shall maintain, at the corporate trust
office of the Trustee, a Certificate Account, the Upper-Tier Group I
Distribution Account and the Upper Tier Group II Distribution Account each of
which is to be held by the Trustee in the name of the Trust for the benefit of
the Owners of the Certificates and the Group I Insurer, as their interests may
appear.

         SECTION 7.3. THE GROUP I INSURANCE POLICY.

         (a) With respect to the Group I Certificates only, on each
Determination Date the Trustee shall determine with respect to the immediately
following Payment Date: the Group I Monthly Remittance Amount on deposit in the
Certificate Account on such Payment Date (disregarding the amounts of any Group
I Insured Payment) and equal to the sum of (x) such amounts excluding the amount
of any Group I Monthly Excess Cashflow amounts included in such amounts and
excluding an amount equal to the Premium Amount together with any Trustee's Fees
described in 7.5(b)(i) for the related Payment Date, plus (y) any amounts of
Group I Monthly Excess Cashflow to be applied on such Payment Date and any
amounts available from Group II Monthly Excess Cashflow pursuant to Section
7.5(g)(I); the amounts described in the preceding clause (x) with respect to
Group I and Payment Date, and without regard to any Group I Insured Payment to
be made with respect to such Payment Date, are the "Group I Available Funds";
the sum of the amounts described in the preceding clauses (x) and (y) are the
"Group I Total Available Funds".

         (b) If the Group I Insured Distribution Amount for any, Payment Date
exceeds the Group I Total Available Funds for such Payment Date (after taking
into account the portion of the Group I Principal Distribution Amount to be
actually distributed on such Payment Date without regard to any Group I Insured
Payment to be made with respect to such Payment Date) (such amount being a
"Group I Deficiency Amount"), the Trustee shall complete a Notice in the form of
Exhibit A to the Group I Insurance Policy and submit such notice to the Group I
Insurer no later than 12:00 noon New York City time on the third Business Day
preceding such Payment Date as a claim for a Group I Insured Payment in an
amount equal to such Group I


                                       64
<PAGE>   70
Deficiency Amount. Upon receipt of Group I Insured Payments from the Group I
Insurer under the Group I Insurance Policy, the Trustee shall deposit such Group
I Insured Payments in the Certificate Account.

         (c) The Trustee shall distribute all Group I Insured Payments received,
or the proceeds thereof, in accordance with Sections 7.5(b) and (d) to the
Owners of the Group I Certificates.

         (d) The Trustee shall (i) receive Group I Insured Payments as
attorney-in-fact of each Owner of the Group I Certificates of the related Class
receiving any Group I Insured Payment from the Group I Insurer and (ii) disburse
such Group I Insured Payment to the Owners of the Group I Certificates as set
forth in Sections 7.5(b) and (d). The Group I Insurer shall be entitled to
receive the related Group I Reimbursement Amount pursuant to Sections 7.5(f)
hereof with respect to each Group I Insured Payment made by the Group I Insurer.
The Trustee hereby agrees on behalf of each Owner of Group I Certificates and
the Trust for the benefit of the Group I Insurer that it recognizes that to the
extent the Group I Insurer makes Group I Insured Payments, either directly or
indirectly (as by paying through the Trustee), to the Owners of such Group I
Certificates, the Group I Insurer will be entitled to receive the Group I
Reimbursement Amount pursuant to Sections 7.5(f).

         (e) The Trustee shall receive, as attorney-in-fact of each Owner of a
Group I Certificate, any Group I Insured Payment from the Group I Insurer and
disburse the same to each Owner of a Group I Certificate in accordance with the
provisions of Section 7.3. Group I Insured Payments disbursed by the Trustee
from proceeds of the Group I Insurance Policy shall not be considered payment by
the Trust Fund nor shall such payments discharge the obligation of the Trust
Fund with respect to the Group I Certificates, and the Group I Insurer shall
become the owner of such unpaid amounts due from the Trust Fund in respect of
the Group I Certificates. The Trustee hereby agrees on behalf of each Owner of a
Group I Certificate for the benefit of the Group I Insurer that it recognizes
that to the extent the Group I Insurer makes any Group I Insured Payment, either
directly or indirectly (as by paying through the Trustee), to the Group I
Certificateholders, the Group I Insurer will be subrogated to the rights of the
Group I Certificateholder with respect to such Group I Insured Payment, shall be
deemed to the extent of payments so made to be a registered Owner of any Group I
Certificates and shall receive all future distributions until all such Group I
Insured Payments by the Group I Insurer, together with interest thereon at the
interest rate borne by the related Group I Certificates applicable of such date
(including any interest on such amounts at the Late Payment Rate), have been
fully reimbursed. To evidence such subrogation, the Trustee shall, or shall
cause the Certificate Registrar to, note the Group I Insurer's rights as
subrogee on the registration books maintained by the Trustee or the Certificate
Registrar upon receipt from the Group I Insurer of proof of payment of any Group
I Insured Payment. The effect of the foregoing provisions is that, to the extent
of Group I Insured Payments made by it, the Group I Insurer shall be paid before
payment of the balance of the distributions are made to the other Owners of the
Group I Certificates.

         SECTION 7.4. [RESERVED]

         SECTION 7.5. FLOW OF FUNDS.

         (a) (i) The Trustee shall deposit to the Certificate Account with

proceeds of any liquidation of the assets of the Trust, all remittances made to
the Trustee pursuant to Section 8.08(d)(iii) and the Monthly Remittance Amount

    (including, with respect to the Class A-7 Certificates, the Component I
    Current Interest and the Component I Interest Carry Forward Amount) without
    any priority among such Class A Certificates; provided, that if the Group I
    Interest Amount Available is not sufficient to make a full distribution of
    interest with respect to all Classes of the Class A Certificates related to
    Group I, the Group I Interest Amount Available will be distributed among the
    outstanding Classes of Class A Certificates related to Group I pro rata
    based on the aggregate amount of interest due on each such Class, and the
    amount of the shortfall will be carried forward; and

         (iv) Fourth, the Group I Monthly Excess Cashflow Amount shall be
    applied or distributed as provided in subsection (f) of this Section 7.5.

         (c) With respect to the Upper Tier Group II Distribution Account on
each Payment Date, the Trustee shall make the following disbursements from the

    Group II;

         (ii) Second, to the Owners of the Class A-8 Certificates, the Class A-8
    Current Interest and the Class A-8 Interest Carry Forward Amount and to the

    II Interest Carry Forward Amounts related to Component II, without any
    priority among such Class A Certificates; provided, that if the Group II
    Interest Amount Available is not sufficient to make a full distribution of
    interest with respect to all Classes of the Class A Certificates related to
    Group II, the Group II Interest Amount Available will be distributed among
    the outstanding Classes of Class A Certificates related to Group II pro rata
    based on the aggregate amount of interest due on each such Class, and the
    amount of the shortfall will be carried forward;


                                       66

         (iii) Third, to the extent of the Group II Interest Amount Available
    remaining, to the Owners of the Class M-1 Certificates, the Class M-1
    Current Interest;

         (iv) Fourth, to the extent of the Group II Interest Amount Available
    then remaining, to the Owners of the Class M-2 Certificates, the Class M-2

    been reduced to zero;

         (ii) the excess of (x) the Group I Principal Distribution Amount over
    (y) the amount distributed in clause (d)(i) above shall be distributed to
    the Owners of the Class A-2 Certificates, the Class A-3 Certificates, the
    Class A-4 Certificates and the Class A-5 Certificates, sequentially in that

         (iii) the excess of (x) the Group I Principal Distribution Amount over

         be applied as a payment of principal with respect to the Subordinate

    principal that would have been distributed to such Class M-1 Certificates
    will be distributed to the related Class M-2 and Class B-1 Certificates in

    Certificates has been reduced to zero, all amounts of principal that would
    have been distributed on such Class M-2 Certificates will be distributed to
    the related Class B-1; and (y) on any Payment Date on which the sum of the
    Certificate Principal Balance of the Subordinate Certificates and the Group
    II Overcollateralization Amount is zero, any amounts of principal payable to
    the Owners of the Group II Certificates on such Payment Date shall be
    distributed pro rata.

         (f) On any Payment Date, the Group I Monthly Excess Cashflow Amount is
required to be applied in the following order of priority on such Payment Date:

                  (A) to the Master Servicer to the extent of any unreimbursed
         or unrecoverable Delinquency Advances or Servicing Advances (including
         Nonrecoverable Advances and Special Advances); and

                  (B) to the Supplemental Interest Payment Account, the
         Supplemental Interest Amount then due to the Owners of the Group II

                  (C) to fund a distribution to the Owners of the Class R
         Certificates.

         (iii) On each Payment Date, and after taking into account all
    distributions on such Payment Date, the Trustee shall allocate the excess of
    the Group II Certificate Principal Balance over the aggregate Loan Balance
    of the Mortgage Loans in Group II as of the end of the related Remittance
    Period to reduce the Certificate Principal Balances of the Subordinate
    Certificates related to Group II in the following order of priority:

                  (A) to the Class B-1 Certificates until the Class B-1
         Certificate Principal Balance is reduced to zero;

                  (B) to the Class M-2 Certificates until the Class M-2
         Certificate Principal Balance is reduced to zero; and

Principal Balance of the related Certificates.

         (k) The rights of the Owners to receive distributions from the proceeds
of the Trust Estate and all ownership interests of the Owners in such
distributions, shall be as set forth in this Agreement. In this regard, all
rights of the Owners of the Class R Certificates to receive distributions in
respect of the Class R Certificates, and all ownership interests of the Owners
of the Class R Certificates in and to such distributions, shall be subject and
subordinate to the preferential rights of the holders of the Offered
Certificates to receive distributions thereon and the ownership interests of
such Owners in such distributions, as described herein. In accordance with the
foregoing, the ownership interests of the Owners of the Class R Certificates in
amounts deposited in the Accounts from time to time shall not vest unless and
until such amounts are distributed in respect of the Class R Certificates in
accordance with the terms of this Agreement. Notwithstanding anything contained
in this Agreement to the contrary, the Owners of the Class R Certificates shall
not be required to refund any amount properly distributed on the Class R
Certificates pursuant to this Section 7.5.

    this clause (d)(ii) to mature on the next Business Day after the date of
    such investment).

         (e) For purposes of investment, the Trustee shall aggregate all amounts
on deposit in the Accounts. All income or other gain from investments in the

<PAGE>   82
         SECTION 7.9. ADDITIONAL REPORTS BY TRUSTEE.

         (a) The Trustee shall report to the Sponsor, the Group I Insurer and
the Master Servicer with respect to the amount then held in each Account
(including investment earnings accrued or scheduled to accrue) held by the
Trustee and the identity of the investments included therein, as the Sponsor,
the Master Servicer or the Group I Insurer may from time to time request.
Without limiting the generality of the foregoing, the Trustee shall, at the
request of the Sponsor, the Master Servicer or the Group I Insurer, transmit
promptly to the Sponsor, the Group I Insurer and the Master Servicer copies of
all accounting of receipts in respect of the Mortgage Loans furnished to it by
the Master Servicer and shall notify the Sponsor, the Group I Insurer and the
Master Servicer if any such receipts have not been received by the Trustee.

         (b) The Trustee shall immediately report to the Group I Insurer,
Sponsor and Master Servicer with respect to its actual knowledge, without
independent investigation, of any breach of any of the representations or
warranties relating to individual Mortgage Loans set forth in any Master
Transfer Agreement or in Section 3.3(a) hereof.

         SECTION 7.10. SUPPLEMENTAL INTEREST PAYMENT ACCOUNT, SUPPLEMENT
INTEREST PAYMENTS AND CLASS R DISTRIBUTION ACCOUNT.

         (a) The parties hereto do hereby create and establish a trust, the
"Advanta Supplemental Interest Trust 1998-1" (the "Supplemental Interest
Trust"). The Supplemental Interest Trust shall hold a trust account, the
"Supplemental Interest Payment Account" to be held by the Trustee in its name on
behalf of the Supplemental Interest Trust. None of the assets of the
Supplemental Interest Trust shall be considered assets of either REMIC, and any
amounts transferred from the Upper-Tier REMIC to the Supplemental Interest Trust
shall be treated as distributions with respect to the Class R Certificates.

         (b) The amount, if any, on deposit in the Supplemental Interest Payment
Account on any Payment Date is the "Supplemental Interest Payment Amount
Available" on such Payment Date.

         If, on any Determination Date the Trustee determines that the
Supplemental Interest Payment Amount Available to be available on the next
Payment Date is less than the excess of (x) the excess of (i) the Full Interest
Distribution Amount over (ii) the Current Interest over (y) the Supplemental
Interest Payment Amount Available as of such Payment Date (the "Formula Interest
Shortfall"), the Trustee shall demand that the Designated Residual Owner fund
the Formula Interest Shortfall on the related Payment Date.

         The amount so funded by the Designated Residual Owner on any such
Payment Date is the "Interest Advance" for such Payment Date.

         On each Payment Date, the Trustee shall withdraw from the Supplemental
Interest Payment Account and pay to the Owners of the Capped Certificates which
are not receiving the Full Interest Distribution Amount with respect to such
Class on such Distribution Date the amount by which such Full Interest
Distribution Amount with respect to such Class exceeds the Current Interest with
respect to such Class on such Payment Date (the "Capped Interest Shortfall"). To
the extent that the Supplemental Interest Payment Amount Available is less than
the Formula Interest Shortfall, the Supplemental Interest Payment Amount
Available shall be applied on a pro rata basis to the Capped Certificates with
respect to Group I (as a group) and to the Capped Certificates with respect to
Group II (as a group) in amounts equal to the


                                       77
<PAGE>   83
product of (a) a fraction, the numerator of which is the Capped Interest
Shortfall with respect to such Group and the denominator of which is the Formula
Interest Shortfall and (b) the Supplemental Interest Payment Amount Available.
To the extent that the Supplemental Interest Payment Amount so allocated to the
Capped Certificates with respect to Group I is less than the Formula Interest
Shortfall with respect to Group I, the Supplemental Interest Payment Amount so
allocated shall be applied on a pro rata basis to the Capped Certificates with
respect to Group I, in amounts equal to the product of (a) a fraction, the
numerator of which is the Capped Interest Shortfall with respect to such Class
and the denominator of which is the Capped Interest Shortfall with respect to
such Group and (b) the Supplement Interest Payment Amount Available allocated to
Group I. To the extent that the Supplemental Interest Payment Amount so
allocated to the Capped Certificates with respect to Group II is less than the
Formula Interest Shortfall with respect to Group II, the Supplemental Interest
Payment Amount so allocated shall be applied to the Capped Certificates with
respect to Group II, in direct order of such Class's seniority (i.e., Component
II, Class M-1 and Class B-1, if any of such Classes are Capped Certificates).

         (c) Any portion of the Supplemental Interest Payment Amount Available
after application of clause (b) above shall be applied in the following order of
priority:

         (i) first, to the Designated Residual Owner, as reimbursement for
    unpaid Interest Advances, together with interest thereon, with the earliest
    Interest Advances being deemed to be paid first;

         (ii) second, to the owners of the Class R Certificates the remainder
    pro rata in accordance with their Percentage Interests.

                          SERVICING AND ADMINISTRATION
                                OF MORTGAGE LOANS

         SECTION 8.1. MASTER SERVICER AND SUB-SERVICERS.

         (a) Acting directly or through one or more Sub-Servicers as provided in
Section 8.3, the Master Servicer, as master servicer, shall service and
administer the Mortgage Loans in accordance with this Agreement and on behalf of
the Trustee and the Group I Insurer and with reasonable care, and using that
degree of skill and attention that the Master exercises with respect to
comparable mortgage loans that it services for itself or others, and shall have
full power and authority, acting alone, to do or cause to be done any and all
things in connection with such servicing and administration which it may deem
necessary or desirable.

         (b) The duties of the Master Servicer shall include collecting and
posting of all payments, responding to inquiries of Mortgagors or by federal,
state or local government authorities with respect to the Mortgage Loans,
investigating delinquencies, reporting tax information to Mortgagors in
accordance with its customary practices and accounting for collections and
furnishing monthly and annual statements to the Trustee and the Group I Insurer,
as applicable, with respect to distributions, paying Compensating Interest and
making Delinquency Advances and Servicing Advances pursuant hereto. The Master
Servicer shall follow its customary standards, policies and procedures in
performing its duties as Master Servicer. The Master Servicer shall cooperate
with the Trustee and furnish to the Trustee with reasonable promptness
information in its possession as may be necessary or appropriate to enable


                                       78
<PAGE>   84
the Trustee to perform its tax reporting duties hereunder. The Trustee shall
furnish the Master Servicer or any Sub-servicer with any powers of attorney and
other documents necessary or appropriate to enable the Master Servicer or any
Sub-servicer to carry out its servicing and administrative duties hereunder.

         (c) Without limiting the generality of the foregoing, the Master
Servicer (i) shall continue, and is hereby authorized and empowered by the
Trustee, to execute and deliver, on behalf of itself, the Owners, the Group I
Insurer and the Trustee or any of them, any and all instruments of satisfaction
or cancellation, or of full release or discharge and all other comparable
instruments, with respect to the Mortgage Loans and with respect to the related
Properties; (ii) may consent to any modification of the terms of any Note not
expressly prohibited hereby if the effect of any such modification (x) will not
be to affect materially and adversely the security afforded by the related
Property, the timing of receipt of any payments required hereby or the interests
of the Group I Insurer and (y) will not cause the Upper-Tier REMIC or the
Lower-Tier REMIC to fail to qualify as a REMIC.

         (d) The Master Servicer shall have the right using that degree of skill
and attention that the Master Servicer exercises with respect to comparable
mortgage loans that it services for itself or others, to approve applications of
Mortgagors for consent to (i) partial releases of Mortgages, (ii) alterations to
Properties and (iii) removal, demolition or division of Properties. No
application for approval shall be considered by the Master Servicer unless: (x)
the provisions of the related Note and Mortgage have been complied with; (y) the
Combined Loan-to-Value Ratio (which may, for this purpose, be determined at the
time of any such action in a manner reasonably acceptable to the Trustee) and
the Mortgagor's debt-to-income ratio after any release does not exceed the
Combined Loan-to-Value Ratio and debt-to-income ratio applicable to such
Mortgage Loan at origination and (z) the lien priority of the related Mortgage
is not adversely affected; provided, however, that the foregoing requirements
(x), (y) and (z) shall not apply to any such situation described in this
paragraph if such situation results from any condemnation or easement activity
by a governmental entity.

         (e) The parties intend that each of the Lower-Tier REMIC and the
Upper-Tier REMIC shall constitute, and that the affairs of each shall be
conducted so as to qualify each as a REMIC. In furtherance of such intention,
the Master Servicer covenants and agrees that it shall act as agent (and the
Master Servicer is hereby appointed to act as agent) on behalf of each such
REMIC and that in such capacity it shall: (i) use its best efforts to conduct
the affairs of each such REMIC at all times that any Class of Certificates are
outstanding so as to maintain the status of each such REMIC as a REMIC under the
REMIC Provisions; (ii) not knowingly or intentionally take any action or omit to
take any action that would cause the termination of the REMIC status of either
such REMIC or that would subject the Trust to tax and (iii) exercise reasonable
care not to allow either such REMIC to receive income from the performance of
services or from assets not permitted under the REMIC Provisions to be held by
each REMIC.

         (f) The Master Servicer may, and is hereby authorized to, perform any
of its servicing responsibilities with respect to all or certain of the Mortgage
Loans through a Sub-Servicer as it may from time to time designate, but no such
designation of a Sub-Servicer shall serve to release the Master Servicer from
any of its obligations under this Agreement. Such Sub-Servicer shall have all
the rights and powers of the Master Servicer with respect to such Mortgage Loans
under this Agreement.

         (g) Without limiting the generality of the foregoing, but subject to
Sections 8.13 and 8.14, the Master Servicer in its own name or in the name of a
Sub-Servicer may be


                                       79
<PAGE>   85
authorized and empowered pursuant to a power of attorney executed and delivered
by the Trustee to execute and deliver, and may be authorized and empowered by
the Trustee, to execute and deliver, on behalf of itself, the Owners, the Group
I Insurer and the Trustee or any of them, (i) any and all instruments of
satisfaction or cancellation or of partial or full release or discharge and all
other comparable instruments with respect to the Mortgage Loans and with respect
to the Properties, (ii) and to institute foreclosure proceedings or obtain a
deed in lieu of foreclosure so as to effect ownership of any Property on behalf
of the Trustee, and (iii) to hold title to any Property upon such foreclosure or
deed in lieu of foreclosure on behalf of the Trustee; provided, however, that
Section 8.14(a) shall constitute a power of attorney from the Trustee to the
Master Servicer or any Sub-servicer to execute an instrument of satisfaction (or
assignment of mortgage without recourse) with respect to any Mortgage Loan paid
in full (or with respect to which payment in full has been escrowed). Subject to
Sections 8.13 and 8.14, the Trustee shall furnish the Master Servicer and any
Sub-servicer with any powers of attorney and other documents as the Master
Servicer or such Sub-Servicer shall reasonably request to enable the Master
Servicer and such Sub-Servicer to carry out their respective servicing and
administrative duties hereunder.

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

         (i) Servicing Advances incurred by the Master Servicer or any
Sub-Servicer in connection with the servicing of the Mortgage Loans (including
any penalties in connection with the payment of any taxes and assessments or
other charges) on any Property shall be recoverable by the Master Servicer or
such Sub-Servicer to the extent described in Section 8.9(c) and in Sections
7.5(h)(i)(A) and 7.5(h)(ii)(B).

         SECTION 8.2. COLLECTION OF CERTAIN MORTGAGE LOAN PAYMENTS.

         (a) The Master Servicer shall, to the extent such procedures shall be
consistent with this Agreement and the terms and provisions of any applicable
Insurance Policies, follow Accepted Servicing Practices. Consistent with the
foregoing, the Master Servicer may in its discretion (i) waive any assumption
fees, late payment charges, charges for checks returned for insufficient funds,
prepayment fees, if any, or other fees which may be collected in the ordinary
course of servicing the Mortgage Loans, (ii) if a Mortgagor is in default or
about to be in default because of a Mortgagor's financial condition, arrange
with the Mortgagor a schedule for the payment of delinquent payments due on the
related Mortgage Loan; provided, however, the Master Servicer shall not
reschedule the payment of delinquent payments more than one time in any twelve
consecutive months with respect to any Mortgagor.

         (b) The Master Servicer shall hold in escrow on behalf of the related
Mortgagor all Prepaid Installments received by it, and shall apply such Prepaid
Installments as directed by such Mortgagor and as set forth in the related Note.

         SECTION 8.3. SUB-SERVICING AGREEMENTS BETWEEN MASTER SERVICER AND
SUB-SERVICERS. The Master Servicer may enter into Sub-Servicing Agreements for
any servicing and administration of Mortgage Loans with any institution which is
in compliance with the laws of each state necessary to enable it to perform its
obligations under such Sub-Servicing Agreement. The Master Servicer shall give
notice to the Group I Insurer and the Trustee of the appointment of any
Sub-Servicer and shall furnish to the Group I Insurer and the Trustee a copy of
the Subservicing Agreement. For purposes of this Agreement, the Master shall be
deemed to have received payments on Mortgage Loans when any Sub-Servicer has
received such payments.


                                       80
<PAGE>   86
Any such Sub-Servicing Agreement shall be consistent with and not violate the
provisions of this Agreement.

         SECTION 8.4. SUCCESSOR SUB-SERVICERS. The Master Servicer may
terminate any Sub-Servicing Agreement in accordance with the terms and
conditions of such Sub-Servicing Agreement and to either itself directly service
the related Mortgage Loans itself or enter into a Sub-Servicing Agreement with a
successor Sub-Servicers that qualifies under Section 8.3.

         SECTION 8.5. LIABILITY OF MASTER SERVICER. The Master Servicer shall
not be relieved of its obligations under this Agreement notwithstanding any
Sub-Servicing Agreement or any of the provisions of this Agreement relating to
agreements or arrangements between the Master Servicer and a Sub-Servicer or
otherwise, and the Master Servicer shall be obligated to the same extent and
under the same terms and conditions as if it alone were servicing and
administering the Mortgage Loans. The Master Servicer shall be entitled to enter
into any agreement with a Sub-Servicer for indemnification of the Master by such
Sub-Servicer and nothing contained in such Sub-Servicing Agreement shall be
deemed to limit or modify this Agreement. The Trust shall not indemnify the
Master Servicer for any losses due to the Master Servicer's negligence.

         SECTION 8.6. NO CONTRACTUAL RELATIONSHIP BETWEEN SUB-SERVICER AND
TRUSTEE OR THE OWNERS. Any Sub-Servicing Agreement and any other transactions
or services relating to the Mortgage Loans involving a Sub-Servicer shall be
deemed to be between the Sub-Servicer and the Master Servicer alone and the
Group I Insurer, the Trustee and the Owners shall not be deemed parties thereto
and shall have no claims, rights, obligations, duties or liabilities with
respect to any Sub-Servicer except as set forth in Section 8.7.

         SECTION 8.7. ASSUMPTION OR TERMINATION OF SUB-SERVICING AGREEMENT BY
TRUSTEE. In connection with the assumption of the responsibilities, duties and
liabilities and of the authority, power and rights of the Master Servicer
hereunder by the Trustee pursuant to Section 8.20, it is understood and agreed
that the Master Servicer's rights and obligations under any Sub-Servicing
Agreement then in force between the Master Servicer and a Sub-Servicer may be
assumed or terminated by the Trustee at its option. Any termination fee due
under any such Sub-Servicing agreement shall be paid by the preceding Master
Servicer but in no event shall the Trustee be liable for any such fee.

         The Master Servicer shall, upon request of the Trustee, but at the
expense of the Master Servicer, deliver to the assuming party documents and
records relating to each Sub-Servicing Agreement and an accounting of amounts
collected and held by it and otherwise use its best reasonable efforts to effect
the orderly and efficient transfer of the Sub-Servicing Agreements to the
assuming party, without the payment of any fee by the Trustee, notwithstanding
any contrary provision in any Sub-Servicing Agreement.

         SECTION 8.8. PRINCIPAL AND INTEREST ACCOUNT.

         (a) The Master Servicer and/or each Sub-servicer, as applicable, shall
establish in the name of the Trust for the benefit of the Owners of the
Certificates and the Group I Insurer, as their interests may appear, and
maintain at one or more Designated Depository Institutions the Principal and
Interest Account.


                                       81
<PAGE>   87
         Subject to Subsections (c) and (e) below, the Master Servicer and any
Sub-servicer shall deposit all receipts related to the Mortgage Loans to the
Principal and Interest Account on a daily basis (but no later than the first
Business Day after receipt).

         On the Startup Day and each day thereafter, as applicable, the Sponsor
and/or the Master Servicer shall deposit to the Principal and Interest Account
all receipts related to the Mortgage Loans which relate to or are received on or
after the Cut-Off Date.

         (b) All funds in the Principal and Interest Account may only be held
(i) uninvested, up to the limits insured by the FDIC or (ii) invested in
Eligible Investments. The Principal and Interest Account shall be held in trust
in the name of the Trust and for the benefit of the Owners of the Certificates
and the Group I Insurer. Any investment earnings on funds held in the Principal
and Interest Account shall be for the account of the Master Servicer and may
only be withdrawn from the Principal and Interest Account by the Master Servicer
immediately following the remittance of the Monthly Remittance Amounts by the
Master Servicer. Any references herein to amounts on deposit in the Principal
and Interest Account shall refer to amounts net of such investment earnings. Any
investment losses are at the expense of the Master Servicer and shall be
replaced on or prior to the Remittance Date.

         (c) Subject to Subsection (e) below, the Master Servicer shall deposit
to the Principal and Interest Account all principal and interest collections on
the Mortgage Loans received on or after the Cut-Off Date including any Prepaid
Installments, Prepayments and Net Liquidation Proceeds, all Loan Purchase Prices
and Substitution Amounts received or paid by the Master Servicer with respect to
the Mortgage Loans, other recoveries or amounts related to the Mortgage Loans
received by the Master Servicer, Compensating Interest and Delinquency Advances
together with any amounts which are reimbursable from the Principal and Interest
Account, but net of (i) the Servicing Fee with respect to each Mortgage Loan and
other servicing compensation to the Master Servicer as permitted by Section 8.15
hereof, (ii) principal (including Prepayments) collected on the related Mortgage
Loans prior to the Cut-Off Date, (iii) interest accruing on the related Mortgage
Loans prior to the Cut-Off Date and (iv) Net Liquidation Proceeds to the extent
such Net Liquidation Proceeds exceed the sum of the Loan Balance of the related
Mortgage Loan and accrued and unpaid interest thereon.

         (d) (i) The Master Servicer may make withdrawals from the Principal and
Interest Account only for the following purposes:

                  (1) to effect the timely remittance to the Trustee of the
         Monthly Remittance Amounts due on the Remittance Date;

                  (2) to reimburse itself pursuant to Section 8.9(a) hereof for
         unreimbursed Delinquency Advances and Servicing Advances and
         Nonrecoverable Advances;

                  (3) to withdraw investment earnings on amounts on deposit in
         the Principal and Interest Account;

                  (4) to withdraw amounts that have been deposited to the
         Principal and Interest Account in error; and

                  (5) to clear and terminate the Principal and Interest Account
         following the termination of the Trust Estate pursuant to Article X.


                                       82
<PAGE>   88
         (ii) On the tenth day of each month, the Master Servicer shall send to
    the Trustee a report, in the form of a computer tape, detailing the payments
    on the Mortgage Loans during the prior Remittance Period. Such tape shall be
    in the form and have the specifications as may be agreed to between the
    Master Servicer and the Trustee from time to time. The Group I Insurer shall
    have the right to request this computer tape upon providing 3 Business Days
    written notice to the Master Servicer.

         (iii)On each Remittance Date the Master Servicer shall remit to the
    Trustee by wire transfer, or otherwise make funds available in immediately
    available funds for deposit in the Certificate Account pursuant to Section
    7.5 of this Agreement, (x) for Group I, the Group I Interest Remittance
    Amount and the Group I Principal Remittance Amount and (y) for Group II, the
    Group II Interest Remittance Amount and the Group II Principal Remittance
    Amount.

         (e) To the extent that the ratings, if any, then assigned to the
unsecured debt of the Master Servicer or of the Master Servicer's ultimate
corporate parent are satisfactory to the Group I Insurer, the Trustee and each
Rating Agency, then the requirement to maintain the Principal and Interest
Account may be waived by an instrument signed by the Group I Insurer, Trustee
and each Rating Agency, and the Master Servicer may be allowed to co-mingle with
its general funds the amounts otherwise required to be deposited to the
Principal and Interest Account, on such terms and subject to such conditions as
the Group I Insurer, the Trustee and each Rating Agency may permit.

         SECTION 8.9. DELINQUENCY ADVANCES, COMPENSATING INTEREST AND SERVICING
ADVANCES.

         (a) The Master Servicer is required, not later than each Remittance
Date, to deposit into the Principal and Interest Account an amount equal to the
sum of the interest portions (net of the Servicing Fees) due, but not collected,
with respect to Delinquent Mortgage Loans during the prior Remittance Period,
but only if, in its good faith business judgment, the Master Servicer reasonably
believes that such amount will ultimately be recovered from the related Mortgage
Loan. Such amounts are "Delinquency Advances".

         The Master Servicer shall be permitted to fund its payment of
Delinquency Advances on any Remittance Date and to reimburse itself for any
Delinquency Advances paid from the Master Servicer's own funds, from collections
on the related Mortgage Loan. The Master Servicer may use funds deposited to the
Principal and Interest Account subsequent to the related Remittance Period and
shall deposit into the Principal and Interest Account with respect thereto (i)
late collections from the Mortgagor whose Delinquency gave rise to the shortfall
which resulted in such Delinquency Advance and (ii) Net Liquidation Proceeds
recovered on account of the related Mortgage Loan to the extent of the amount of
aggregate Delinquency Advances related thereto or (iii) from its own funds. If
not therefore recovered from the related Mortgagor or the related Net
Liquidation Proceeds, Delinquency Advances constituting Nonrecoverable Advances
shall be recoverable pursuant to Sections 7.5(h)(i)(A) and 7.5(h)(ii)(A) hereof.

         (b) On or prior to each Remittance Date, the Master Servicer shall
deposit in the Principal and Interest Account with respect to any full
Prepayment received on a Mortgage Loan during the related Remittance Period out
of its own funds without any right of reimbursement therefor, an amount equal to
the difference between (x) 30 days' interest at the Mortgage Loan's Coupon Rate
(less the Servicing Fee) on the Loan Balance of such Mortgage Loan as of the
first day of the related Remittance Period and (y) to the extent not previously


                                       83
<PAGE>   89
advanced, the interest (less the Servicing Fee) paid by the Mortgagor with
respect to the Mortgage Loan during such Remittance Period (any such amount paid
by the Master Servicer, "Compensating Interest"). The Master Servicer shall in
no event be required to pay Compensating Interest with respect to any Remittance
Period in an amount in excess of the aggregate Servicing Fee received by the
Master Servicer with respect to all Mortgage Loans for such Remittance Period.

         (c) The Master Servicer will pay all "out-of-pocket" costs and expenses
incurred in the performance of its servicing obligations, including, but not
limited to, the cost of (i) Preservation Expenses, (ii) any enforcement or
judicial proceedings, including foreclosures, and (iii) the management and
liquidation of REO Property, but is only required to pay such costs and expenses
to the extent the Master Servicer reasonably believes such costs and expenses
will increase Net Liquidation Proceeds on the related Mortgage Loan. Each such
amount so paid will constitute a "Servicing Advance". The Master Servicer may
recover Servicing Advances (x) from the Mortgagors to the extent permitted by
the Mortgage Loans, from Liquidation Proceeds realized upon the liquidation of
the related Mortgage Loan and (y) as provided in Sections 7.5(h)(i)(A) and
7.5(h)(ii)(A) hereof. In no case may the Master Servicer recover Servicing
Advances from principal and interest payments on any Mortgage Loan or from any
amounts relating to any other Mortgage Loan except as provided pursuant to
Sections 7.5(h)(i)(A) and 7.5(h)(ii)(A) hereof.

         (d) On each Remittance Date in April and May of 1998, the Master
Servicer shall make two Special Advances, one with respect to Group I and one
with respect to Group II equal to the sum of (x) one-month's interest,
calculated at the weighted average Pass-Through Rate (applicable to the April or
May 1998 Payment Date, as the case may be, for the classes of Offered
Certificates related to such Group) with respect to all Mortgage Loans not
having a payment due during March or April 1998, as the case may be, (y) with
respect to Group I, the Premium Amount with respect to such Mortgage Loans for
the April or May 1998 Payment Date, as the case may be, and (z) the Trustee's
Fee with respect to such Mortgage Loans for the April or May 1998 Payment Date,
as the case may be; the amounts of such advances shall be included in the
related Interest Remittance Amount. Reimbursement of Special Advances shall be
made only as provided in Sections 7.5(h)(i)(A) and 7.5(h)(ii)(A).

         SECTION 8.10. PURCHASE OF MORTGAGE LOANS. The Master Servicer may, but
is not obligated to, purchase for its own account any Mortgage Loan which
becomes Delinquent, in whole or in part, as to four consecutive monthly
installments or any Mortgage Loan as to which enforcement proceedings have been
brought by the Master Servicer or by any Sub-servicer pursuant to Section 8.13.
Any such Loan so purchased shall be purchased by the Master Servicer on a
Remittance Date at a purchase price equal to the Loan Purchase Price thereof,
which purchase price shall be deposited in the Principal and Interest Account.
Notwithstanding the foregoing, the Master Servicer may not purchase any such
Mortgage Loan unless the Master Servicer has delivered to the Trustee an opinion
of counsel experienced in federal income tax matters acceptable to the Trustee
to the effect that such a purchase would not constitute a Prohibited Transaction
for the Trust or otherwise subject the Trust to tax and would not jeopardize the
status of either the Upper-Tier REMIC or the Lower-Tier REMIC as a REMIC.

         SECTION 8.11. MAINTENANCE OF INSURANCE.

         (a) The Master Servicer shall cause to be maintained with respect to
each Mortgage Loan a hazard insurance policy with a generally acceptable carrier
that provides for fire and extended coverage, and which provides for a recovery
by the Master Servicer on behalf of the


                                       84
<PAGE>   90
Trust of insurance proceeds relating to such Mortgage Loan in an amount not less
than the least of (i) the outstanding principal balance of the Mortgage Loan,
(ii) the minimum amount required to compensate for damage or loss on a
replacement cost basis and (iii) the full insurable value of the premises.

         (b) If the Mortgage Loan at the time of origination relates to a
Property in an area identified in the Federal Register by the Federal Emergency
Management Agency as having special flood hazards, the Master Servicer will
cause to be maintained with respect thereto a flood insurance policy in a form
meeting the requirements of the current guidelines of the Federal Insurance
Administration with a generally acceptable carrier in an amount representing
coverage, and which provides for a recovery by the Master Servicer on behalf of
the Trust of insurance proceeds relating to such Mortgage Loan of not less than
the least of (i) the outstanding principal balance of the Mortgage Loan, (ii)
the minimum amount required to compensate for damage or loss on a replacement
cost basis and (iii) the maximum amount of insurance that is available under the
Flood Disaster Protection Act of 1973. The Master Servicer shall indemnify the
Trust and the Group I Insurer out of the Master Servicer's own funds for any
loss to the Trust and the Group I Insurer resulting from the Master Servicer's
failure to maintain the insurance required by this Section.

         (c) In the event that the Master Servicer shall obtain and maintain a
blanket policy insuring against fire, flood and hazards of extended coverage on
all of the Mortgage Loans, then, to the extent such policy names the Master
Servicer as loss payee and provides coverage in an amount equal to the aggregate
unpaid principal balance on the Mortgage Loans without co-insurance, and
otherwise complies with the requirements of this Section 8.11, the Master
Servicer shall be deemed conclusively to have satisfied its obligations with
respect to fire and hazard insurance coverage under this Section 8.11, it being
understood and agreed that such blanket policy may contain a deductible clause,
in which case the Master Servicer shall, in the event that there shall not have
been maintained on the related Property a policy complying with the preceding
paragraphs of this Section 8.11, and there shall have been a loss which would
have been covered by such policy, deposit in the Principal and Interest Account
from the Master Servicer's own funds the difference, if any, between the amount
that would have been payable under a policy complying with the preceding
paragraphs of this Section 8.11 and the amount paid under such blanket policy.
Upon the request of the Trustee or the Group I Insurer, the Master Servicer
shall cause to be delivered to the Trustee and the Group I Insurer, a certified
true copy of such policy.

         SECTION 8.12. DUE-ON-SALE CLAUSES; ASSUMPTION AND SUBSTITUTION
AGREEMENTS. When a Property has been or is about to be conveyed by the
Mortgagor, the Master Servicer shall, to the extent it has knowledge of such
conveyance or prospective conveyance, exercise its rights to accelerate the
maturity of the related Mortgage Loan under any "due-on-sale" clause contained
in the related Mortgage or Note; provided, however, that the Master Servicer
shall not exercise any such right if (i) the "due-on-sale" clause, in the
reasonable belief of the Master Servicer, is not enforceable under applicable
law or (ii) the Master Servicer reasonably believes that to permit an assumption
of the Mortgage Loan would not materially and adversely affect the interest of
the Owners or of the Group I Insurer. In such event, the Master Servicer shall
enter into an assumption and modification agreement with the person to whom such
property has been or is about to be conveyed, pursuant to which such person
becomes liable under the Note and, unless prohibited by applicable law or the
Mortgage Documents, the Mortgagor remains liable thereon. If the foregoing is
not permitted under applicable law, the Master Servicer is authorized to enter
into a substitution of liability agreement with such person, pursuant to which
the original Mortgagor is released from liability and such person is substituted


                                       85
<PAGE>   91
as Mortgagor and becomes liable under the Note; provided, however, that to the
extent any such substitution of liability agreement would be delivered by the
Master Servicer outside of its usual procedures for mortgage loans held in its
own portfolio the Master Servicer shall, prior to executing and delivering such
agreement, obtain the prior written consent of the Control Party. The Mortgage
Loan, as assumed, shall conform in all respects to the requirements,
representations and warranties of this Agreement. The Master 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
File and which shall, for all purposes, be considered a part of such File to the
same extent as all other documents and instruments constituting a part thereof.
The Master Servicer shall be responsible for recording or causing the
recordation any such assumption or substitution agreements. In connection with
any such assumption or substitution agreement, the required monthly payment on
the related Mortgage Loan shall not be changed but shall remain as in effect
immediately prior to the assumption or substitution, the stated maturity or
outstanding principal amount of such Mortgage Loan shall not be changed nor
shall any required monthly payments of principal or interest be deferred or
forgiven. Any fee collected by the Master Servicer or the Sub-Servicer for
consenting to any such conveyance or entering into an assumption or substitution
agreement shall be retained by or paid to the Master Servicer as additional
servicing compensation.

         Notwithstanding the foregoing paragraph or any other provision of this
Agreement, the Master Servicer shall not be deemed to be in default, breach or
any other violation of its obligations hereunder by reason of any assumption of
a Mortgage Loan by operation of law or any assumption which the Master Servicer
may be restricted by law from preventing, for any reason whatsoever.

         SECTION 8.13. REALIZATION UPON DEFAULTED MORTGAGE LOANS.

         (a) The Master Servicer shall foreclose upon or otherwise comparably
effect the ownership on behalf of the Trust of Properties relating to defaulted
Mortgage Loans as to which no satisfactory arrangements can be made for
collection of Delinquent payments and which the Master Servicer has not
purchased pursuant to Section 8.10. In connection with such foreclosure or other
conversion, the Master Servicer shall exercise such of the rights and powers
vested in it hereunder, and use the same degree of care and skill in their
exercise or use, as prudent mortgage lenders would exercise or use under the
circumstances in the conduct of their own affairs, including, but not limited
to, advancing funds for the payment of taxes, amounts due with respect to Senior
Liens, and insurance premiums. Any amounts so advanced shall constitute
"Servicing Advances" within the meaning of Section 8.9(c) hereof. The Master
Servicer shall sell any REO Property within 35 months of its acquisition by the
Trust, unless the Master Servicer obtains for the Trustee an opinion of counsel
experienced in federal income tax matters, addressed to the Trustee, the Group I
Insurer and the Master Servicer, to the effect that the holding by the Trust of
such REO Property for any greater period will not result in the imposition of
taxes on "Prohibited Transactions" of the Trust or any REMIC therein as defined
in Section 860F of the Code or cause either the Lower-Tier REMIC or the
Upper-Tier REMIC to fail to qualify as a REMIC under the REMIC Provisions at any
time that any Certificates are outstanding. Notwithstanding the generality of
the foregoing provisions, the Master Servicer shall manage, conserve, protect
and operate each REO Property for the Owners and the Group I Insurer solely for
the purpose of its prompt disposition and sale in a manner which does not cause
such REO Property to fail to qualify as "foreclosure property" within the
meaning of Section 860G(a)(8) of the Code or result in the receipt by the
Lower-Tier REMIC or the Upper Tier REMIC of any "income from non-permitted
assets" within the meaning of Section 860F(a)(2)(B)


                                       86
<PAGE>   92
of the Code or any "net income from foreclosure property" which is subject to
taxation under the REMIC Provisions. Pursuant to its efforts to sell such REO
Property, the Master Servicer shall either itself or through an agent selected
by the Master Servicer protect and conserve such REO Property in the same manner
and to such extent as is customary in the locality where such REO Property is
located and may, incident to its conservation and protection of the interests of
the Owners, rent the same, or any part thereof, as the Master Servicer deems to
be in the best interest of the Owners for the period prior to the sale of such
REO Property. The Master Servicer shall take into account the existence of any
hazardous substances, hazardous wastes or solid wastes, as such terms are
defined in the Comprehensive Environmental Response Compensation and Liability
Act, the Resource Conservation and Recovery Act of 1976, or other federal, state
or local environmental legislation, on a REO Property in determining whether to
foreclose upon or otherwise comparably convert the ownership of such REO
Property. With respect to any Mortgage Loan secured by a mixed use REO Property,
the Master Servicer shall, prior to foreclosing upon or otherwise comparably
effecting the ownership in the name of the Master Servicer on behalf of the
Trust, either (x) perform a "phase one environmental study" of such REO Property
or (y) repurchase such REO Property at the Loan Purchase Price.

         Notwithstanding the generality of the foregoing provisions, the Master
Servicer shall manage, conserve, protect and operate each REO Property for the
Owners solely for the purpose of its prompt disposition and sale in a manner
which does not cause such REO Property to fail to qualify as "foreclosure
property" within the meaning of Section 860G(a)(8) of the Code or result in the
receipt by the Trust of any "income from non-permitted assets" within the
meaning of Section 860F(a)(2)(B) of the Code or any "net income from foreclosure
property" which is subject to taxation under the REMIC Provisions. Pursuant to
its efforts to sell such REO Property, the Master Servicer shall either itself
or through an agent selected by the Master Servicer protect and conserve such
REO Property in the same manner and to such extent as is customary in the
locality where such REO Property is located and may, incident to its
conservation and protection of the interests of the Owners, rent the same, or
any part thereof, as the Master Servicer deems to be in the best interest of the
Owners for the period prior to the sale of such REO Property. The Master
Servicer shall take into account the existence of any hazardous substances,
hazardous wastes or solid wastes, as such terms are defined in the Comprehensive
Environmental Response Compensation and Liability Act, the Resource Conservation
and Recovery Act of 1976, or other federal, state or local environmental
legislation, on a Property in determining whether to foreclose upon or otherwise
comparably convert the ownership of such Property.

         (b) The Master Servicer shall determine, with respect to each defaulted
Mortgage Loan, when it has recovered, whether through trustee's sale,
foreclosure sale or otherwise, all amounts it expects to recover from or on
account of such defaulted Mortgage Loan, whereupon such Mortgage Loan shall
become a "Liquidated Loan" and shall promptly deliver to the Group I Insurer a
related liquidation report with respect to such Liquidated Loan.

         SECTION 8.14. TRUSTEE TO COOPERATE; RELEASE OF FILES.

         (a) Upon the payment in full of any Mortgage Loan (including the
repurchase of any Mortgage Loan or any liquidation of such Mortgage Loan through
foreclosure or otherwise), or the receipt by the Master Servicer or any
Sub-servicer of a notification that payment in full will be escrowed in a manner
customary for such purposes, the Master Servicer or any Sub-servicer shall
deliver to the Trustee a Master Servicer's Trust Receipt. Upon receipt of such
Master Servicer's Trust Receipt, the Trustee shall promptly release the related
File, in trust to (i) the Master Servicer, (ii) an escrow agent or (iii) any
employee, agent or attorney of the


                                       87
<PAGE>   93
Trustee, in each case pending its release by the Master Servicer, such escrow
agent or such employee, agent or attorney of the Trustee, as the case may be.
Upon any such payment in full, or the receipt of such notification that such
funds have been placed in escrow, the Master Servicer or any Sub-servicer is
authorized to give, as attorney-in-fact for the Trustee and the mortgagee under
the Mortgage which secured the Note, an instrument of satisfaction (or
assignment of Mortgage without recourse) regarding the Property relating to such
Mortgage, which instrument of satisfaction or assignment, as the case may be,
shall be delivered to the Person or Persons entitled thereto against receipt
therefor of payment in full, it being understood and agreed that no expense
incurred in connection with such instrument of satisfaction or assignment, as
the case may be, shall be chargeable to the Principal and Interest Account. In
lieu of executing any such satisfaction or assignment, as the case may be, the
Master Servicer or any Sub-servicer may prepare and submit to the Trustee, a
satisfaction (or assignment without recourse, if requested by the Person or
Persons entitled thereto) in form for execution by the Trustee with all
requisite information completed by the Master Servicer or any Sub-servicer; in
such event, the Trustee shall execute and acknowledge such satisfaction or
assignment, as the case may be, and deliver the same with the related File, as
aforesaid.

         (b) From time to time and as appropriate in the servicing of any
Mortgage Loan, including, without limitation, foreclosure or other comparable
conversion of a Mortgage Loan or collection under any applicable Insurance
Policy, the Trustee shall (except in the case of the payment or liquidation
pursuant to which the related File is released to an escrow agent or an
employee, agent or attorney of the Trustee), upon request of the Master Servicer
or any Sub-servicer and delivery to the Trustee of a Master Servicer's Trust
Receipt, release the related File to the Master Servicer and shall execute such
documents as shall be necessary to the prosecution of any such proceedings,
including, without limitation, an assignment without recourse of the related
Mortgage to the Master Servicer; provided that the Master Servicer shall not
have received and not returned at any one time more than 10% of the entire
number of Files. The Trustee shall complete in the name of the Trustee any
endorsement in blank on any Note prior to releasing such Note to the Master
Servicer or any Sub-servicer. Such receipt shall obligate the Master Servicer or
any Sub-servicer to return the File to the Trustee when the need therefor by the
Master Servicer or any Sub-servicer no longer exists unless the Mortgage Loan
shall be liquidated, in which case, upon receipt of the liquidation information,
in physical or electronic form, the Master Servicer's Trust Receipt shall be
released by the Trustee to the Master Servicer or any Sub-servicer.

         (c) No costs associated with the procedures described in this Section
8.14 shall be an expense of the Trust.

         (d) The provisions set forth in Subsections (a) and (b) may be
superseded by any waiver of the Document Delivery Requirement as may be given by
the Group I Insurer and the Rating Agencies pursuant to Section 3.5(j) hereof.

         (e) Each Master Servicer's Trust Receipt 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 Master Servicer and the Trustee shall mutually agree. The Trustee shall
promptly release the related File(s) within five (5) to seven (7) business days
of receipt of a properly completed Master Servicer's Trust Receipt pursuant to
clauses (i), (ii) or (iii) above or such shorter period as may be agreed upon by
the Master Servicer and the Trustee. Receipt of a Master Servicer's Trust
Receipt pursuant to clauses (i), (ii) or (iii) above shall be authorization to
the Trustee to release such Files, provided the Trustee has determined that such
Master Servicer's Trust Receipt has been executed, with respect to clauses (i)
or (ii)


                                       88
<PAGE>   94
above, or approved, with respect to clause (iii) above, by an Authorized Officer
of the Master Servicer or any Sub-servicer, and so long as the Trustee complies
with its duties and obligations under this Agreement. If the Trustee is unable
to release the Files within the time frames previously specified, the Trustee
shall immediately notify the Master Servicer or any Sub-servicer indicating the
reason for such delay, but in no event shall such notification be later than
five business days after receipt of a Master Servicer's Trust Receipt. If the
Master Servicer is required to pay penalties or damages due solely to the
Trustee's negligent failure to release the related 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 Master Servicer remits to the Trustee Master
Servicer's Trust Receipts pursuant to clauses (ii) or (iii) above, the Master
Servicer or any Sub-servicer shall also submit to the Trustee a summary of the
total amount of such Master Servicer's Trust Receipts requested on such day by
the same method as described in such clauses (ii) or (iii) above.

         SECTION 8.15. SERVICING COMPENSATION. As compensation for its
activities hereunder, the Master Servicer shall be entitled to retain the amount
of the Servicing Fee with respect to each Mortgage Loan. Additional servicing
compensation in the form of prepayment charges, release fees, bad check charges,
assumption fees, late payment charges, or any other servicing-related fees, Net
Liquidation Proceeds not required to be deposited in the Principal and Interest
Account pursuant to Section 8.8(c)(v) and similar items may, to the extent
collected from Mortgagors, be retained by the Master Servicer.

         SECTION 8.16. ANNUAL STATEMENT AS TO COMPLIANCE. The Master Servicer,
at its own expense, will deliver to the Trustee, the Group I Insurer and each
Rating Agency, on or before the last day of March of each year, commencing in
1998, an Officer's Certificate stating, as to each signer thereof, that (i) a
review of the activities of the Master Servicer during such preceding calendar
year and of performance under this Agreement has been made under such officers'
supervision, and (ii) to the best of such officers' knowledge, based on such
review, the Master Servicer has fulfilled all its obligations under this
Agreement for such year, or, if there has been a default in the fulfillment of
all such obligations, specifying each such default known to such officers and
the nature and status thereof including the steps being taken by the Master
Servicer to remedy such defaults.

         SECTION 8.17. ANNUAL INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS' REPORTS.
On or before the last day of March of each year, commencing in 1998, the
Master Servicer, at its own expense, shall cause to be delivered to the Trustee,
the Group I Insurer and each Rating Agency a letter or letters of a firm of
independent, nationally recognized certified public accountants reasonably
acceptable to the Control Party stating that such firm has, with respect to the
Master Servicer's overall servicing operations (i) performed applicable tests in
accordance with the compliance testing procedures as set forth in Appendix 3 of
the Audit Guide for Audits of HUD Approved Nonsupervised Mortgagees or (ii)
examined such operations in accordance with the requirements of the Uniform
Single Audit Program for Mortgage Bankers, and in either case stating such
firm's conclusions relating thereto.

         SECTION 8.18. ACCESS TO CERTAIN DOCUMENTATION AND INFORMATION REGARDING
THE MORTGAGE LOANS. The Master Servicer shall provide to the Trustee, the Group
I Insurer, the FDIC and the supervisory agents and examiners of each of the
foregoing access to the documentation regarding the Mortgage Loans required by
applicable state and federal regulations, such access being afforded without
charge but only upon reasonable request and during normal business hours at the
offices of the Master Servicer designated by it.

<PAGE>   95
         SECTION 8.19. ASSIGNMENT OF AGREEMENT. The Master Servicer may not
assign its obligations under this Agreement, in whole or in part, unless it
shall have first obtained the written consent of the Trustee and the Group I
Insurer, which such consent shall not be unreasonably withheld; provided,
however, that any assignee must meet the eligibility requirements set forth in
Section 8.20(g) hereof for a successor servicer. Notice of any such assignment
shall be given by the Master Servicer to the Trustee, the Group I Insurer and
Moody's.

         SECTION 8.20. REMOVAL OF MASTER SERVICER; RESIGNATION OF MASTER
SERVICER.

         (a) The Trustee, with the consent of the Group I Insurer (or the Owners
pursuant to Section 6.11 hereof) may remove the Master Servicer upon the
occurrence of any of the following events:

         (i) The Master Servicer shall fail to deliver to the Trustee any

    for relief or seeking to take advantage of any insolvency law or file an
    answer admitting the material allegations of a petition filed against it in
    any bankruptcy, reorganization or insolvency proceeding or (vi) take
    corporate action for the purpose of effecting any of the foregoing;

         (iii) If without the application, approval or consent of the Master
    Servicer, a proceeding shall be instituted in any court of competent
    jurisdiction, under any law relating to bankruptcy, insolvency,
    reorganization or relief of debtors, seeking in respect of the Master
    Servicer an order for relief or an adjudication in bankruptcy,
    reorganization, dissolution, winding up, liquidation, a composition or
    arrangement with creditors, a readjustment of debts, the appointment of a
    trustee, receiver, liquidator or custodian or similar entity with respect to

    and, if such proceeding is being contested by the Master Servicer in good
    faith, the same shall (A) result in the entry of an order for relief or any
    such adjudication or appointment or (B) continue undismissed or pending and
    unstayed for any period of seventy-five (75) consecutive days; or

         (iv) The Master Servicer shall fail to perform any one or more of its
    obligations hereunder other than the obligations contemplated by Subsection
    8.20(i) above, and shall continue in default thereof for a period of sixty
    (60) days after notice by the Trustee or the Group I Insurer of said
    failure; provided, however, that if the Master Servicer can demonstrate to
    the reasonable satisfaction of the Control Party that it is diligently
    pursuing remedial action, then the cure period may be extended with the
    written approval of the Control Party; or


                                       90
<PAGE>   96
         (v) The Master Servicer shall fail to cure any breach of any of its
    representations and warranties set forth in Section 3.2 which materially and
    adversely affects the interests of the Owners or the Group I Insurer for a
    period of thirty (30) days after the Master Servicer's discovery or receipt
    of notice thereof; provided, however, that if the Master Servicer can
    demonstrate to the reasonable satisfaction of the Control Party that it is
    diligently pursuing remedial action, then the cure period may be extended
    with the written approval of the Control Party.

         (b) The Control Party also may remove the Master Servicer upon the
occurrence of any of the following events:

         (i) a Group I Deficiency Amount; provided, however, that the Group I
    Insurer shall have no right to remove the Master Servicer under this clause
    (i) if the Master Servicer can demonstrate to the reasonable satisfaction of
    the Group I Insurer that such event was due to circumstances beyond the
    control of the Master Servicer; or

         (ii) the failure by the Master Servicer to make any required Servicing
    Advance; or

         (iii) the failure by the Master Servicer to perform any one or more of
    its obligations hereunder or under the Insurance Agreement, which failure
    materially and adversely affects the interests of the Group I Insurer and
    the Trustee; or

         (iv) the failure by the Master Servicer to make any required
    Delinquency Advance, any Special Advance or to pay any Compensating
    Interest; or

         (v) the occurrence of a Servicer Termination Delinquency Rate Trigger
    or a Servicer Termination Loss Trigger, as such terms are defined in the
    Insurance Agreement; or

         (vi) the enactment of any law by a legislative body that declares, or
    any finding or ruling by a court of competent jurisdiction, that the
    Insurance Agreement or this Agreement is not valid and binding on the
    Sponsor or the Master Servicer;

provided, however, with respect to clause (iv), if the Master Servicer can
demonstrate to the reasonable satisfaction of the Control Party that any such
event was due to circumstances beyond the control of the Master Servicer, such
event shall not be considered an event of termination of the Master Servicer;

provided, however, that (x) prior to any removal of the Master Servicer by the
Control Party pursuant to clauses (i) or (ii) of this Section 8.20(b), the
Master Servicer shall first have been given by the Control Party and by
registered or certified mail, notice of the occurrence of one or more of the
events set forth in clauses (i), (ii) or (iii) above and the Master Servicer
shall not have remedied, or shall not have taken actions satisfactory to the
Control Party to remedy, such event or events within 30 days (60 days with
respect to clause (iii)) after the Master Servicer's receipt of such notice
(provided, however, that if the Master Servicer can demonstrate to the
reasonable satisfaction of the Control Party that it is diligently pursuing
remedial action, then the cure period in each case may be extended with the
written approval of the Control Party) and (v) in the event of the refusal or
inability of the Master Servicer to make any required Delinquency Advance or
Special Advance or to pay any Compensating Interest or Monthly Remittance, such
removal shall be effective (without the requirement of any action on the part of
the Group I Insurer or of the


                                       91
<PAGE>   97
Trustee) at 4 p.m. on the second Business Day following the day on which the
Trustee or the Group I Insurer notifies an Authorized Officer of the Master
Servicer that a required Delinquency Advance or Special Advance has not been
received by the Trustee. Upon the Trustee's determination that a required
Delinquency Advance or Special Advance or payment of Compensating Interest has
not been made by the Master Servicer, the Trustee shall so notify in writing an
Authorized Officer of the Master Servicer and the Group I Insurer as soon as is
reasonably practical.

         (c) The Master Servicer shall not resign from the obligations and
duties hereby imposed on it, except upon determination that its duties hereunder
are no longer permissible under applicable law or are in material conflict by
reason of applicable law with any other activities carried on by it, the other
activities of the Master Servicer so causing such a conflict being of a type and
nature carried on by the Master Servicer at the date of this Agreement. Any such
determination permitting the resignation of the Master Servicer shall be
evidenced by an opinion of counsel to such effect which shall be delivered to
the Trustee and the Group I Insurer.

         (d) No removal or resignation of the Master Servicer shall become
effective until the Trustee or a successor servicer shall have assumed the
Master Servicer's responsibilities and obligations in accordance with this
Section. If no successor servicer is available, the Trustee shall act as
successor servicer and perform all of the obligations of this Section,
including, without limitation, making Delinquency Advances and paying
Compensating Interest; provided, however, that the Trustee will not be obligated
to act as successor servicer if it is legally unable to perform its duties
hereunder.

         (e) Upon removal or resignation of the Master Servicer, the Master
Servicer also shall promptly deliver or cause to be delivered to a successor
servicer or the Trustee all the books and records (including, without
limitation, records kept in electronic form) that the Master Servicer has
maintained for the Mortgage Loans, including all tax bills, assessment notices,
insurance premium notices and all other documents as well as all original
documents then in the Master Servicer's possession.

         (f) Any collections received by the Master Servicer after removal or
resignation shall be endorsed by it to the Trustee and remitted directly and
immediately to the Trustee or the successor Master Servicer.

         (g) Upon removal or resignation of the Master Servicer, the Trustee (x)
may solicit bids for a successor servicer as described below, and (y) pending
the appointment of a successor Master Servicer as a result of soliciting such
bids, shall serve as Master Servicer. The Trustee shall, if it is unable to
obtain a qualifying bid and is prevented by law from acting as Master Servicer,
appoint, or petition a court of competent jurisdiction to appoint, any housing
and home finance institution, bank or mortgage servicing institution which has
shareholders' equity of not less than $10,000,000, as determined in accordance
with generally accepted accounting principles, and acceptable to the Group I
Insurer as the successor to the Master Servicer hereunder in the assumption of
all or any part of the responsibilities, duties or liabilities of the Master
Servicer hereunder. The compensation of any successor servicer (including,
without limitation, the Trustee) so appointed shall be the aggregate Servicing
Fees, together with the other servicing compensation in the form of assumption
fees, late payment charges or otherwise as provided in Sections 8.8 and 8.15;
provided, however, that if the Trustee acts as successor Master Servicer then
the Sponsor agrees to pay to the Trustee at such time that the Trustee becomes
such successor Master Servicer a fee of twenty-five dollars ($25.00) for each
Mortgage Loan then


                                       92
<PAGE>   98
included in the Trust Estate. The Trustee shall be obligated to serve as
successor Master Servicer whether or not the $25.00 fee described in the
preceding sentence is paid by the Sponsor, but shall in any event be entitled to
receive, and to enforce payment of, such fee from the Sponsor.

         (h) In the event the Trustee solicits bids as provided above, 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 Master Servicer shall be entitled to the full amount of the aggregate
Servicing Fees as servicing compensation, together with the other servicing
compensation in the form of assumption fees, late payment charges or otherwise
as provided in Sections 8.8 and 8.15. 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
qualified party submitting the highest satisfactory bid. The Trustee shall
deduct from any sum received by the Trustee from the successor to the Master
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. After such deductions, the
remainder of such sum shall be paid by the Trustee to the Master Servicer at the
time of such sale, transfer and assignment to the Master Servicer's successor.

         (i) The Trustee and such successor shall take such action, consistent
with this Agreement, as shall be necessary to effectuate any such succession.
The Master Servicer agrees to cooperate with the Trustee and any successor
Master Servicer in effecting the termination of the Master Servicer's servicing
responsibilities and rights hereunder and shall promptly provide the Trustee or
such successor Master Servicer, as applicable, all documents and records
reasonably requested by it to enable it to assume the Master Servicer's
functions hereunder and shall promptly also transfer to the Trustee or such
successor Master Servicer, as applicable, all amounts which then have been or
should have been deposited in the Principal and Interest Account by the Master
Servicer or which are thereafter received with respect to the Mortgage Loans.
Neither the Trustee nor any other successor Master 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 Master
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 Master Servicer or (iii) any breaches of a predecessor Master Servicer.

         (j) The Trustee or any other successor Master Servicer, upon assuming
the duties of Master Servicer hereunder, shall immediately make all Delinquency
Advances and pay all Compensating Interest which the Master Servicer has
theretofore failed to remit with respect to the Mortgage Loans; provided,
however, that if the Trustee is acting as successor Master Servicer, the Trustee
shall only be required to make Delinquency Advances (including the Delinquency
Advances described in this clause (j)) if, in the Trustee's reasonable good
faith judgment, such Delinquency Advances will ultimately be recoverable from
the related Mortgage Loans.

         (k) The Master Servicer which is being removed or is resigning shall
give notice to the Mortgagors and to each Rating Agency of the transfer of the
servicing to the successor.

         (l) The Trustee shall give notice to the Group I Insurer, each Rating
Agency and to the Owners of the occurrence of any event specified in Section
8.20(a) of which the Trustee has knowledge.


                                       93
<PAGE>   99
         (m) Notwithstanding anything herein to the contrary, upon termination
of the Master Servicer hereunder, any liabilities of the Master Servicer which
accrued prior to such termination shall survive such termination.

         SECTION 8.21. INSPECTIONS BY THE GROUP I INSURER AND THE TRUSTEE;
ERRORS AND OMISSIONS INSURANCE.

         (a) At any reasonable time and from time to time upon reasonable
notice, the Group I Insurer, the Trustee, or any agents or representatives
thereof may inspect the Master Servicer's servicing operations and discuss the
servicing operations of the Master Servicer with any of its officers or
directors. The costs and expenses incurred by the Master Servicer or its agents
or representatives in connection with any such examinations or discussions shall
be paid by the Master Servicer.

         (b) The Master Servicer agrees to maintain errors and omissions
coverage and a fidelity bond, each at least to the extent generally maintained
by prudent mortgage loan servicers having servicing portfolios of a similar
size.

         SECTION 8.22. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO
BUSINESS OF MASTER SERVICER. Any corporation into which the Master Servicer may
be merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which the Master
Servicer shall be a party, or any corporation succeeding to all or substantially
all of the business of the Master Servicer, shall be the successor of the Master
Servicer hereunder, without the execution or filing of any paper or any further
act on the part of any of the parties hereto provided that such corporation
meets the qualifications set forth in Section 8.20(g).

         SECTION 8.23. NOTICES OF MATERIAL EVENTS. The Master Servicer shall
give prompt notice to the Group I Insurer, the Trustee, and each Rating Agency
of the occurrence of any of the following events:

         (a) The submission of any claim or the initiation of any legal process,
litigation or administrative or judicial investigation against the Sponsor, the
Master Servicer or AMHC in any federal, state or local court or before any
governmental body or agency, or before any arbitration board, or any such
proceedings threatened by any governmental agency, which, if adversely
determined, would have a material adverse effect upon any the Sponsor's, the
Master Servicer's or AMHC's ability to perform its obligations under any
Transaction Document;

         (b) The commencement of any proceedings by or against the Sponsor, the
Master Servicer or AMHC under any applicable bankruptcy, reorganization,
liquidation, insolvency or other similar law now or hereafter in effect or of
any proceeding in which a receiver, liquidator, trustee or other similar
official shall have been, or may be, appointed or requested for the Sponsor, the
Master Servicer or AMHC; and

         (c) The receipt of notice from any agency or governmental body having
authority over the conduct of any of the Sponsor's the Master Servicer's or the
AMHC's business that the Sponsor, the Master Servicer or AMHC is to cease and
desist, or to undertake any practice, program, procedure or policy employed by
the Sponsor, the Master Servicer or AMHC in the conduct of the business of any
of them, and such cessation or undertaking will materially adversely affect the
conduct of the Sponsor's, the Master Servicer's or AMHC's business or its


                                       94
<PAGE>   100
ability to perform under the Transaction Documents or materially adversely
affect the financial affairs of the Sponsor, the Master Servicer or AMHC.

                                   ARTICLE IX

                              TERMINATION OF TRUST

         SECTION 9.1. TERMINATION OF TRUST. The Trust created hereunder and all
obligations created by this Agreement will terminate upon the earlier of (i) the
payment to the Owners of all Certificates from amounts other than those
available under the Group I Insurance Policy of all amounts held by the Trustee
and required to be paid to such Owners pursuant to this Agreement upon the later
to occur of (a) the final payment or other liquidation (or any advance made with
respect thereto) of the last Mortgage Loan in the Trust Estate or (b) the
disposition of all property acquired in respect of any Mortgage Loan remaining
in the Trust Estate, (ii) at any time when a Qualified Liquidation of the REMIC
Trust is effected as described below or (iii) as described in Section 9.2 or 9.3
hereof. To effect a termination of this Agreement pursuant to clause (ii) above,
the Owners of all Certificates then Outstanding shall (x) unanimously direct the
Trustee on behalf of the Lower-Tier REMIC and the Upper-Tier REMIC to adopt a
plan of complete liquidation with respect to each of the Mortgage Loan Groups as
contemplated by Section 860F(a)(4) of the Code and (y) provide to the Trustee an
opinion of counsel experienced in federal income tax matters to the effect that
such liquidation constitutes a Qualified Liquidation, and the Trustee either
shall sell the Mortgage Loans and distribute the proceeds of the liquidation of
the Trust Estate, or shall distribute equitably in kind all of the assets of the
Trust Estate to the remaining Owners of the Certificates based on their
interests in the Trust, each in accordance with such plan, so that the
liquidation or distribution of the Trust Estate, the distribution of any
proceeds of the liquidation and the termination of this Agreement occur no later
than the close of the 90th day after the date of adoption of the plan of
liquidation and such liquidation qualifies as a Qualified Liquidation. In no
event, however, will the Trust created by this Agreement continue beyond the
expiration of twenty-one (21) years from the death of the last survivor of the
descendants of Joseph P. Kennedy, the late Ambassador of the United States to
the United Kingdom, living on the date hereof. The Trustee shall give written
notice of termination of the Agreement to each Owner in the manner set forth in
Section 11.5.

         SECTION 9.2. TERMINATION UPON OPTION OF MASTER SERVICER.

         (a) On any Remittance Date on or after the Clean-Up Call Date, the
Master Servicer acting directly or through one or more affiliates may determine
to purchase and may cause the purchase from the Trust of all (but not fewer than
all) Mortgage Loans in the Trust Estate and all property theretofore acquired in
respect of any such Mortgage Loan by foreclosure, deed in lieu of foreclosure,
or otherwise then remaining in the Trust Estate at a price equal to the sum of
(v) the greater of (i) 100% of the aggregate Loan Balances of the related
Mortgage Loans as of the day of purchase minus the amount actually remitted by
the Master Servicer representing the related Monthly Principal Remittance Amount
on such Remittance Date for the related Remittance Period and (ii) the fair
market value of such Mortgage Loans (disregarding accrued interest), (w) the
amount of any difference between the related Monthly Interest Remittance Amount
actually remitted by the Master Servicer on such Remittance Date and the related
Monthly Interest Remittance Amount due on such Remittance Date, (x) the related
Group II Reimbursement Amount, if any, and (y) the aggregate amount of any
Delinquency Advances and Servicing Advances remaining unreimbursed, together
with any accrued and unpaid Servicing Fees, as of such Remittance Date (such
amount, the "Termination Price"). In connection with


                                       95
<PAGE>   101
such purchase, the Master Servicer shall remit to the Trustee all amounts then
on deposit in the Principal and Interest Account for deposit to the Certificate
Account, which deposit shall be deemed to have occurred immediately preceding
such purchase. Notwithstanding the foregoing, the Master Servicer or its
affiliate may not terminate the Trust pursuant to this Section 9.2 without the
consent of the Group I Insurer, if termination would result in a draw on the
Group I Insurance Policy.

         (b) In connection with any such purchase, the Master Servicer shall
provide to the Trustee an opinion of counsel experienced in federal income tax
matters to the effect that such purchase constitutes a Qualified Liquidation of
the Lower-Tier REMIC and Upper-Tier REMIC.

         (c) Promptly following any such purchase, the Trustee will release the
Files to the Master Servicer, or otherwise upon their order, in a manner similar
to that described in Section 8.14 hereof.

         (d) Upon such purchase, the Group I Insurance Policy will terminate and
shall be returned to the Group I Insurer.

         SECTION 9.3. TERMINATION UPON LOSS OF REMIC STATUS.

         (a) Following a (x) final determination by the Internal Revenue
Service, or by a court of competent jurisdiction, in either case from which no
appeal is taken within the permitted time for such appeal, or (y) if any appeal
is taken, following a final determination of such appeal from which no further
appeal can be taken, to the effect that either the Upper-Tier REMIC or
Lower-Tier REMIC do not and will no longer qualify as a "REMIC" pursuant to
Section 860D of the Code (the "Final Determination") or (z) following the
delivery of an opinion of counsel ("REMIC Opinion") to the effect that the
effect of the Final Determination is to increase substantially the probability
that either the Upper-Tier REMIC or Lower-Tier REMIC will no longer qualify as a
"REMIC" pursuant to Section 860D of the Code, on any Remittance Date on or after
the date which is 30 calendar days following such Final Determination, the
Owners of a majority in Percentage Interest represented by the Offered
Certificates then Outstanding may direct the Trustee to adopt a plan of complete
liquidation with respect to the Trust Estate. In connection with such purchase,
the Master Servicer shall remit to the Trustee all amounts then on deposit in
the Principal and Interest Account for deposit in the Certificate Account, which
deposit shall be deemed to have occurred immediately preceding such purchase.

         (b) Upon receipt of such direction from the Owners of such Offered
Certificates or such notice from the Group I Insurer, the Trustee shall notify
the holders of the Class R Certificates of such election to liquidate or such
determination to purchase, as the case may be, (the "Termination Notice"). The
Owner of a majority of the Percentage Interest of the Class R Certificates then
Outstanding may, on any Remittance Date, within 60 days from the date of receipt
of the Termination Notice (the "Purchase Option Period"), at their option,
purchase from the Trust all (but not fewer than all) Mortgage Loans in the Trust
Estate, and all property theretofore acquired by foreclosure, deed in lieu of
foreclosure, or otherwise in respect of any Mortgage Loan then remaining in the
Trust Estate at a purchase price equal to the Termination Price.

         (c) If, during the Purchase Option Period, the Owners of the Class R
Certificates have not exercised the option described in the immediately
preceding paragraph, then upon the expiration of the Purchase Option Period in
the event that the Owners of the Offered


                                       96
<PAGE>   102
Certificates have given the Trustee the direction described in clause (a)(i)
above, the Trustee shall sell the Mortgage Loans and distribute the proceeds of
the liquidation of the Trust Estate, such that, if so directed, the liquidation
of the Trust Estate, the distribution of the proceeds of such liquidation occur
no later than the close of the 60th day, or such later day as the Owners of the
Offered Certificates shall permit or direct in writing, after the expiration of
the Purchase Option Period.

         (d) Following a Final Determination, the Owners of a majority of the
Percentage Interest of the Class R Certificates then Outstanding may, at their
option on any Remittance Date and upon delivery to the Owners of the Offered
Certificates and the Trustee of an opinion of counsel experienced in federal
income tax matters selected by the Owners of such Class R Certificates which
opinion shall be reasonably satisfactory in form and substance to a majority of
the Percentage Interests represented by the Offered Certificates then
Outstanding and the Trustee, to the effect that the effect of the Final
Determination is to increase substantially the probability that the gross income
of either the Upper-Tier REMIC or Lower-Tier REMIC will be subject to federal
taxation, purchase from the Trust all (but not fewer than all) Mortgage Loans in
the Trust Estate, and all property theretofore acquired by foreclosure, deed in
lieu of foreclosure, or otherwise in respect of any Mortgage Loan then remaining
in the Trust Estate at a purchase price equal to the Termination Price. In
connection with such purchase, the Master Servicer shall remit to the Trustee
all amounts then on deposit in the Principal and Interest Account for deposit to
the Certificate Account, which deposit shall be deemed to have occurred
immediately preceding such purchase. The foregoing opinion shall be deemed
satisfactory unless the Owners of a majority of the Percentage Interest
represented by the Offered Certificates then Outstanding or the Trustee give the
Owners of a majority of the Percentage Interest of the Class R Certificates
notice that such opinion is not satisfactory within thirty days after receipt of
such opinion.

         SECTION 9.4. DISPOSITION OF PROCEEDS. The Trustee shall, upon receipt
thereof, deposit the proceeds of any liquidation of the Trust Estate pursuant to
this Article IX to the Certificate Account; provided, however, that any amounts
representing Servicing Fees, unreimbursed Delinquency Advances or unreimbursed
Servicing Advances theretofore funded by the Master Servicer from the Master
Servicer's own funds shall be paid by the Trustee to the Master Servicer.

         SECTION 9.5. NETTING OF AMOUNTS. If any Person paying the Termination
Price would receive a portion of the amount so paid, such Person may net any
such amount against the Termination Price otherwise payable.

                                    ARTICLE X

                                   THE TRUSTEE

to examine the same to determine whether or not they conform to the requirements
of this Agreement.

         (b) Notwithstanding the appointment of the Master Servicer hereunder,
the Trustee is hereby empowered to perform the duties of the Master Servicer

pursuant to Section 8.20 hereof or otherwise. Specifically, and not in
limitation of the foregoing, the Trustee shall have the power:

    Compensating Interest, and

    subsection (a) of this Section;

    Trustee was negligent in ascertaining the pertinent facts; and

         (iii) the Trustee shall not be liable with respect to any action taken
    or omitted to be taken by it in good faith in accordance with the direction
    of the Group I Insurer or of the Owners of a majority in Percentage Interest
    of the Certificates of the affected Class or Classes and the Group I Insurer
    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 relating to such Certificates.

         (d) Whether or not therein expressly so provided, every provision of
this Agreement relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section.

         (e) No provision of this Agreement shall require the Trustee to expend
or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder, or in the exercise of any of its
rights or powers, if it shall have reasonable grounds for believing that
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

<PAGE>   104
         (f) The permissive right of the Trustee to take actions enumerated in
this Agreement shall not be construed as a duty and the Trustee shall not be
answerable for other than its own negligence or willful misconduct.

         (g) The Trustee shall be under no obligation to institute any suit, or
to take any remedial proceeding under this Agreement, or to take any steps in
the execution of the trusts hereby created or in the enforcement of any rights
and powers hereunder until it shall be indemnified to its satisfaction against
any and all costs and expenses, outlays and counsel fees and other reasonable
disbursements and against all liability, except liability which is adjudicated
to have resulted from its negligence or willful misconduct, in connection with
any action so taken. The Trustee shall receive from the Sponsor promptly upon
demand therefor, reimbursement of expenses as are described in the fee quote
letter, dated August 28, 1997 and executed by the Sponsor.

         SECTION 10.2. REMOVAL OF TRUSTEE FOR CAUSE.

         (a) The Trustee may be removed pursuant to paragraph (b) hereof upon

notice of the occurrence of any such event of which the Sponsor is aware.

         (b) If any event described in Paragraph (a) occurs and is continuing,
then and in every such case (i) the Group I Insurer or (ii) with the prior
written consent (which shall not be unreasonably withheld) of the Group I
Insurer (x) the Sponsor or (y) the Owners of a majority of the Percentage

resigns pursuant to Section 10.9 hereof, immediately, concurrently with the
giving of notice to the Trustee, and without delaying the 30 days required for
notice therein, appoint a successor Trustee pursuant to the terms of Section

         SECTION 10.3. CERTAIN RIGHTS OF THE TRUSTEE. Except as otherwise

so published. If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, it shall, upon the request of

         SECTION 10.9. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

         (a) No resignation or removal of the Trustee and no appointment of a
successor trustee pursuant to this Article X shall become effective until the

         (b) The Trustee, or any trustee or trustees hereafter appointed, may

mailing notice of resignation by first-class Mail, postage prepaid, to the Group
I Insurer and the Owners at their addresses appearing on the Register. A copy of
such notice shall be sent by the resigning Trustee to each Rating Agency. Upon
receiving notice of resignation, the Sponsor shall promptly appoint a successor
trustee or trustees by written instrument, in duplicate, executed on behalf of
the Trust by an Authorized Officer of the Sponsor, one copy of which instrument
shall be delivered to the Trustee so resigning and one copy to the successor
trustee or trustees. If no successor trustee shall have been 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, or any Owner may, on
behalf of himself and all others similarly situated, petition any such court for
the appointment of a successor trustee. Such court may thereupon, after such
notice, if any, as it may deem proper and prescribe, appoint a successor
trustee.

         (c) If at any time the Trustee shall cease to be eligible under Section
10.8 hereof and shall fail to resign after written request therefor by the
Sponsor or by the Group I Insurer, the Group I Insurer or the Sponsor (with the
written consent of the Group I Insurer) may remove the Trustee and appoint a
successor trustee by written instrument, in duplicate, executed on behalf of the
Trust by an Authorized Officer of the Sponsor, one copy of which instrument
shall be delivered to the Trustee so removed and one copy to the successor
trustee.

         (d) The Owners of a majority of the Percentage Interests represented by
the Offered Certificates, or, if there are no Offered Certificates then
Outstanding, by such majority of the Percentage Interests represented by Class R
Certificates then Outstanding may at any time, with the prior written consent of
the Group I Insurer, remove the Trustee and appoint a successor trustee by
delivering to the Trustee to be removed, to the successor trustee so appointed,
to the Sponsor and to the Group I Insurer, copies of the record of the act taken
by the Owners, as provided for in Section 11.3 hereof.

         (e) If the Trustee fails to perform its duties in accordance with the
terms of this Agreement or becomes ineligible to serve as Trustee, the Group I
Insurer or, if the last sentence of Section 11.18 hereof is applicable, the
Sponsor may remove the Trustee and appoint a successor trustee by written
instrument, in triplicate, signed by the Group I Insurer and the Sponsor duly
authorized, one complete set of which instruments shall be delivered to the
Sponsor, one complete set to the Group I Insurer, one complete set to the
Trustee so removed and one complete set to the successor Trustee so appointed.

         (f) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of the Trustee for any cause,
the Sponsor shall promptly appoint a successor Trustee acceptable to the Group I
Insurer. If within one year after such resignation, removal or incapability or
the occurrence of such vacancy, a successor Trustee shall be appointed by act of
the Owners of a majority of the Percentage Interests represented by the Offered
Certificates then Outstanding or, if there are no Offered Certificates then
Outstanding, by such majority of the Percentage Interest of the Class R
Certificates delivered to the Sponsor and


                                      102
<PAGE>   108
the retiring Trustee, the successor Trustee so appointed shall forthwith upon
its acceptance of such appointment become the successor Trustee and supersede
the successor Trustee appointed by the Sponsor. If no successor Trustee shall
have been so appointed by the Sponsor or the Owners and shall have accepted
appointment in the manner hereinafter provided, any Owner may, on behalf of
himself and all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Trustee. Such court may
thereupon, after such notice, if any, as it may deem proper and prescribe,
appoint a successor Trustee.

         (g) The Sponsor shall give notice of any removal of the Trustee by
mailing notice of such event by first-class mail, postage prepaid, to the Group
I Insurer and to the Owners as their names and addresses appear in the Register.
Each notice shall include the name of the successor Trustee and the address of
its corporate trust office.

         SECTION 10.10. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR TRUSTEE. Every
successor Trustee appointed hereunder shall execute, acknowledge and deliver to
the Sponsor on behalf of the Trust and to its predecessor Trustee an instrument
accepting such appointment hereunder and stating its eligibility to serve as
Trustee 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 vested with all the rights, powers,
trusts, duties and obligations of its predecessor hereunder; but, on request of
the Sponsor or the successor Trustee, such predecessor Trustee shall, upon
payment of its charges then unpaid, execute and deliver an instrument
transferring to such successor Trustee all of the rights, powers and trusts of
the Trustee so ceasing to act, and shall duly assign, transfer and deliver to
such successor Trustee all property and money held by such Trustee so ceasing to
act hereunder. Upon request of any such successor Trustee, the Sponsor on behalf
of the Trust shall execute any and all instruments for more fully and certainly
vesting in and confirming to such successor Trustee all such rights, powers and
trusts.

         Upon acceptance of appointment by a successor Trustee as provided in
this Section, the Sponsor shall mail notice thereof by first-class mail, postage
prepaid, to the Owners at their last addresses appearing upon the Register. The
Sponsor shall send a copy of such notice to each of the Rating Agencies and the
Group I Insurer. If the Sponsor fails to mail such notice within ten days after
acceptance of appointment by the successor Trustee, the successor Trustee shall
cause such notice to be mailed at the expense of the Trust.

         No successor Trustee shall accept its appointment unless at the time of
such acceptance such successor shall be qualified and eligible under this
Article X.

         SECTION 10.11. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO
BUSINESS OF THE TRUSTEE. Any corporation or association into which the Trustee
may be merged or converted or with which it may be consolidated, or any
corporation or association resulting from any merger, conversion or
consolidation to which the Trustee shall be a party, or any corporation or
association succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto; provided, however, that such corporation or
association shall be otherwise qualified and eligible under this Article X. In
case any Certificates have been executed, but not delivered, by the Trustee then
in office, any successor by merger, conversion or consolidation to such Trustee
may adopt such execution and deliver the Certificates so executed with the same
effect as if such successor Trustee had itself executed such Certificates.


                                      103
<PAGE>   109
         SECTION 10.12. REPORTING; WITHHOLDING. The Trustee shall timely
provide to the Owners the Internal Revenue Service's Form 1099 and any other
statement required by applicable Treasury regulations as determined by the
Sponsor, and shall withhold, as required by applicable law, federal, state or
local taxes, if any, applicable to distributions to the Owners, including, but
not limited to, backup withholding under Section 3406 of the Code and the
withholding tax on distributions to foreign investors under Sections 1441 and
1442 of the Code.

         SECTION 10.13. LIABILITY OF THE TRUSTEE. The Trustee shall be liable
in accordance herewith only to the extent of the obligations specifically
imposed upon and undertaken by the Trustee herein. Neither the Trustee nor any
of the directors, officers, employees or agents of the Trustee shall be under
any liability on any Certificate or otherwise to any Account, the Sponsor, the
Master Servicer or any Owner 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 Trustee
or any such Person against any liability which would otherwise be imposed by
reason of negligent action, negligent failure to act or bad faith in the
performance of duties or by reason of reckless disregard of obligations and
duties hereunder. Subject to the foregoing sentence, the Trustee shall not be
liable for losses on investments of amounts in any Account (except for any
losses on obligations on which the bank serving as Trustee is the obligor). In
addition, the Sponsor and Master Servicer covenant and agree to indemnify the
Trustee, and its officers, directors, employees and agents, including, without
limitation, when the Trustee is acting as Master Servicer, and hold it harmless
against, any and all losses, liabilities, damages, claims or expenses (including
legal fees and expenses) other than those resulting from the negligence or bad
faith of the Trustee. The indemnification provided in this Section 10.13 shall
survive the termination of this Agreement or the resignation or removal of the
Trustee hereunder. The Trustee and any director, officer, employee or agent of
the Trustee may rely and shall be protected in acting or refraining from acting
in good faith on any certificate, notice or other document of any kind prima
facie properly executed and submitted by the Authorized Officer of any Person
respecting any matters arising hereunder.

         SECTION 10.14. APPOINTMENT OF CO-TRUSTEE OR SEPARATE TRUSTEE.
Notwithstanding any other provisions of this Agreement, at any time, for the
purpose of meeting any legal requirements of any jurisdiction in which any part
of the Trust Estate or Property may at the time be located, the Master Servicer
and the Trustee acting jointly shall have the power and shall execute and
deliver all instruments to appoint one or more Persons approved by the Trustee
and the Group I Insurer to act as co-Trustee or co-Trustees, jointly with the
Trustee, of all or any part of the Trust Estate or separate Trustee or separate
Trustees of any part of the Trust Estate, and to vest in such Person or Persons,
in such capacity and for the benefit of the Owners, such title to the Trust
Estate, or any part thereof, and, subject to the other provisions of this
Section 10.14, such powers, duties, obligations, rights and trusts as the Master
Servicer and the Trustee may consider necessary or desirable. If the Master
Servicer shall not have joined in such appointment within 15 days after the
receipt by it of a request so to do, or in the case any event indicated in
Sections 8.20(a) or 8.20(b) shall have occurred and be continuing, the Trustee
alone shall have the power to make such appointment with the consent of the
Group I Insurer. No co-Trustee or separate Trustee hereunder shall be required
to meet the terms of eligibility as a successor Trustee under Section 10.8 and
no notice to Owner of the appointment of any co-Trustee or separate Trustee
shall be required under Section 10.8.

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


                                      104
<PAGE>   110
         (i) All rights, powers, duties and obligations conferred or imposed
    upon the Trustee shall be conferred or imposed upon and exercised or
    performed by the Trustee and such separate Trustee or co-Trustee jointly (it
    being understood that such separate Trustee or co-Trustee is not authorized
    to act separately without the Trustee joining in such act), except to the
    extent that under any law of any jurisdiction in which any particular act or
    acts are to be performed (whether as Trustee hereunder or as successor to
    the Master Servicer hereunder), the Trustee shall be incompetent or
    unqualified to perform such act or acts, in which event such rights, powers,
    duties and obligations (including the holding of title to the Trust Estate
    or any portion thereof in any such jurisdiction) shall be exercised and
    performed singly by such separate Trustee or co-Trustee, but solely at the
    direction of the Trustee;

         (ii) No co-Trustee hereunder shall be held personally liable by reason
    of any act or omission of any other co-Trustee hereunder; and

         (iii) The Master Servicer and the Trustee acting jointly may at any 
    time accept the resignation of or remove any separate Trustee or co-Trustee.

         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 Section 10.14. Each separate Trustee and co-Trustee, upon its acceptance
of the trusts conferred, shall be vested with the estates or property specified
in its instrument of appointment, either jointly with the Trustee or separately,
as may be provided therein, subject to all the provisions of this Agreement,
specifically including every provision of this Agreement relating to the conduct
of, affecting the liability of, or affording protection to, the Trustee. Every
such instrument shall be filed with the Trustee and a copy thereof given to the
Master Servicer.

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

         The Trustee shall give to Moody's, the Sponsor and the Group I Insurer
notice of the appointment of any Co-Trustee or separate Trustee.

                                   ARTICLE XI

                                  MISCELLANEOUS

         SECTION 11.1. COMPLIANCE CERTIFICATES AND OPINIONS. Upon any
application or request by the Sponsor, the Group I Insurer or the Owners to the
Trustee to take any action under any provision of this Agreement, the Sponsor,
the Group I Insurer or the Owners, as the case may be, shall furnish to the
Trustee a certificate stating that all conditions precedent, if any, provided
for in this Agreement relating to the proposed action have been complied with,
except that in the case of any such application or request as to which the
furnishing of any documents is


                                      105
<PAGE>   111
specifically required by any provision of this Agreement relating to such
particular application or request, no additional certificate need be furnished.

         Except as otherwise specifically provided herein, each certificate or
opinion with respect to compliance with a condition or covenant provided for in
this Agreement shall include:

         (a) a statement that each individual signing such certificate or
opinion has read such covenant or condition and the definitions herein relating
thereto;

         (b) a brief statement as to the nature and scope of the examination or
investigation upon which the statements or opinions contained in such
certificate or opinion are based; and

         (c) a statement as to whether, in the opinion of each such individual,
such condition or covenant has been complied with.

         SECTION 11.2. FORM OF DOCUMENTS DELIVERED TO THE TRUSTEE. In any case
where several matters are required to be certified by, or covered by an opinion
of, any specified Person, it is not necessary that all such matters be certified
by, or covered by the opinion of, only one such Person, or that they be so
certified or covered by only one document, but one such Person may certify or
give an opinion with respect to some matters and one or more other such Persons
as to other matters, and any such Person may certify or give an opinion as to
such matters in one or several documents.

         Any certificate of an Authorized Officer of the Trustee may be based,
insofar as it relates to legal matters, upon an opinion of counsel, unless such
Authorized Officer knows, or in the exercise of reasonable care should know,
that the opinion is erroneous. Any such certificate of an Authorized Officer of
the Trustee or any opinion of counsel may be based, insofar as it relates to
factual matter upon a certificate or opinion of, or representations by, one or
more Authorized Officers of the Sponsor or of the Master Servicer, stating that
the information with respect to such factual matters is in the possession of the
Sponsor or of the Master Servicer, unless such Authorized Officer or counsel
knows, or in the exercise of reasonable care should know, that the certificate
or opinion or representations with respect to such matters are erroneous. Any
opinion of counsel may also be based, insofar as it relates to factual matters,
upon a certificate or opinion of, or representations by, an Authorized Officer
of the Trustee, stating that the information with respect to such matters is in
the possession of the Trustee, unless such counsel knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to such matters are erroneous. Any opinion of counsel may be based
on the written opinion of other counsel, in which event such opinion of counsel
shall be accompanied by a copy of such other counsel's opinion and shall include
a statement to the effect that such counsel believes that such counsel and the
Trustee may reasonably rely upon the opinion of such other counsel.

         Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Agreement, they may, but need not, be consolidated and
form one instrument.

         SECTION 11.3. ACTS OF OWNERS.

         (a) Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Agreement to be given or taken by the
Owners may be embodied in


                                      106
<PAGE>   112
and evidenced by one or more instruments of substantially similar tenor signed
by such Owners in person or by an agent duly appointed in writing; and, except
as herein otherwise expressly provided, such action shall become effective when
such instrument or instruments are delivered to the Trustee, and, where it is
hereby expressly required, to the Sponsor and/or the Group I Insurer. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "act" of the Owners signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Agreement and conclusive in favor of the Trustee and the Trust, if made in the
manner provided in this Section.

         (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by the certificate of any notary public or other officer authorized
by law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Whenever
such execution is by an officer of a corporation or a member of a partnership on
behalf of such corporation or partnership, such certificate or affidavit shall
also constitute sufficient proof of his authority.

         (c) The ownership of Certificates shall be proved by the Register.

         (d) Any request, demand, authorization, direction, notice, consent,
waiver or other action by the Owner of any Certificate shall bind the Owner of
every Certificate issued upon the registration of transfer thereof or in
exchange therefor or in lieu thereof, in respect of anything done, omitted or
suffered to be done by the Trustee or the Trust in reliance thereon, whether or
not notation of such action is made upon such Certificates.

         SECTION 11.4. NOTICES, ETC., TO TRUSTEE. Any request, demand,
authorization, direction, notice, consent, waiver or act of the Owners or other
documents provided or permitted by this Agreement to be made upon, given or
furnished to, or filed with the Trustee by any Owner, the Group I Insurer or by
the Sponsor shall be sufficient for every purpose hereunder if made, given,
furnished or filed in writing to or with and received by the Trustee at its
corporate trust office as set forth in Section 2.2 hereof.

         SECTION 11.5. NOTICES AND REPORTS TO OWNERS; WAIVER OF NOTICES. Where
this Agreement provides for notice to Owners of any event or the mailing of any
report to Owners, such notice or report shall be sufficiently given (unless
otherwise herein expressly provided) if mailed, first-class postage prepaid, to
each Owner affected by such event or to whom such report is required to be
mailed, at the address of such Owner as it appears on the Register, not later
than the latest date, and not earlier than the earliest date, prescribed for the
giving of such notice or the mailing of such report. In any case where a notice
or report to Owners is mailed in the manner provided above, neither the failure
to mail such notice or report nor any defect in any notice or report so mailed
to any particular Owner shall affect the sufficiency of such notice or report
with respect to other Owners, and any notice or report which is mailed in the
manner herein provided shall be conclusively presumed to have been duly given or
provided.

         Where this Agreement provides for notice in any manner, such notice may
be waived in writing by any Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Owners shall be filed with the Trustee, but such
filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.


                                      107
<PAGE>   113
         In case, by reason of the suspension of regular mail service as a
result of a strike, work stoppage or similar activity, it shall be impractical
to mail notice of any event to Owners when such notice is required to be given
pursuant to any provision of this Agreement, then any manner of giving such
notice as shall be satisfactory to the Trustee shall be deemed to be a
sufficient giving of such notice.

         Where this Agreement provides for notice to any rating agency that
rated any Certificates, failure to give such notice shall not affect any other
rights or obligations created hereunder.

         SECTION 11.6. RULES BY TRUSTEE AND SPONSOR. The Trustee may make
reasonable rules for any meeting of Owners. The Sponsor may make reasonable
rules and set reasonable requirements for its functions.

         SECTION 11.7. SUCCESSORS AND ASSIGNS. All covenants and agreements in
this Agreement by any party hereto shall bind its successors and assigns,
whether so expressed or not.

         SECTION 11.8. SEVERABILITY. In case any provision in this Agreement or
in the Certificates shall be invalid, illegal or unenforceable, the validity,
legality and enforceability of the remaining provisions shall not in any way be
affected or impaired thereby.

         SECTION 11.9. BENEFITS OF AGREEMENT. Nothing in this Agreement or in
the Certificates, expressed or implied, shall give to any Person, other than the
Owners, the Group I Insurer and the parties hereto and their successors
hereunder, any benefit or any legal or equitable right, remedy or claim under
this Agreement.

         SECTION 11.10. LEGAL HOLIDAYS. In any case where the date of any
Payment Date, any other date on which any distribution to any Owner is proposed
to be paid, or any date on which a notice is required to be sent to any Person
pursuant to the terms of this Agreement shall not be a Business Day, then
(notwithstanding any other provision of the Certificates or this Agreement)
payment or mailing need not be made on such date, but may be made on the next
succeeding Business Day with the same force and effect as if made or mailed on
the nominal date of any such Payment Date, or such other date for the payment of
any distribution to any Owner or the mailing of such notice, as the case may be,
and no interest shall accrue for the period from and after any such nominal
date, provided such payment is made in full on such next succeeding Business
Day.

         SECTION 11.11. GOVERNING LAW. In view of the fact that Owners are
expected to reside in many states and outside the United States and the desire
to establish with certainty that this Agreement will be governed by and
construed and interpreted in accordance with the law of a state having a
well-developed body of commercial and financial law relevant to transactions of
the type contemplated herein, this Agreement and each Certificate shall be
construed in accordance with and governed by the laws of the State of New York
applicable to agreements made and to be performed therein.

         SECTION 11.12. COUNTERPARTS. This instrument 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.


                                      108
<PAGE>   114
         SECTION 11.13. USURY. The amount of interest payable or paid on any
Certificate under the terms of this Agreement shall be limited to an amount
which shall not exceed the maximum nonusurious rate of interest allowed by the
applicable laws of the State of New York or any applicable law of the United
States permitting a higher maximum nonusurious rate that preempts such
applicable New York laws, which could lawfully be contracted for, charged or
received (the "Highest Lawful Rate"). In the event any payment of interest on
any Certificate exceeds the Highest Lawful Rate, the Trust stipulates that such
excess amount will be deemed to have been paid to the Owner of such Certificate
as a result of an error on the part of the Trustee acting on behalf of the Trust
and the Owner receiving such excess payment shall promptly, upon discovery of
such error or upon notice thereof from the Trustee on behalf of the Trust,
refund the amount of such excess or, at the option of such Owner, apply the
excess to the payment of principal of such Certificate, if any, remaining
unpaid. In addition, all sums paid or agreed to be paid to the Trustee for the
benefit of Owners of Certificates for the use, forbearance or detention of money
shall, to the extent permitted by applicable law, be amortized, prorated,
allocated and spread throughout the full term of such Certificates.

         SECTION 11.14. AMENDMENT

         (a) The Trustee, the Sponsor and the Master Servicer, may at any time
and from time to time, with the prior written consent of the Group I Insurer but
without the giving of notice to or the receipt of the consent of the Owners,
amend this Agreement, and the Trustee shall consent to such amendment, for the
purpose of (i) curing any ambiguity, or correcting or supplementing any
provision hereof which may be inconsistent with any other provision hereof, or
to add provisions hereto which are not inconsistent with the provisions hereof,
(ii) upon receipt of an opinion of counsel experienced in federal income tax
matters to the effect that no entity-level tax will be imposed on the REMIC
Trust or upon the transferor of a Class R Certificate as a result of the
ownership of any Class R Certificate by a Disqualified Organization, removing
the restriction on transfer set forth in Section 5.8(b) hereof or (iii)
complying with the requirements of the Code and the regulations proposed or
promulgated thereunder; provided, however, that any such action shall not, as
evidenced by an opinion of counsel delivered to the Trustee, materially and
adversely affect the interests of any Owner (without its written consent).

         (b) The Trustee, the Sponsor and the Master Servicer may, at any time
and from time to time, with the prior written consent of the Group I Insurer but
without the giving of notice to or the receipt of the consent of the Owners,
amend this Agreement, and the Trustee shall consent to such amendment, for the
purpose of changing the definitions of "Group I Targeted Overcollateralization
Amount" and "Group II Targeted Overcollateralization Amount"; provided, however,
that no such change shall affect the weighted average life of the related Class
of Offered Certificates (assuming an appropriate prepayment speed as determined
by the Representative) by more than five percent, as determined by the
Representative.

         (c) This Agreement may also be amended by the Trustee, the Sponsor, and
the Master Servicer at any time and from time to time, with the prior written
approval of the Group I Insurer and not less than a majority of the Percentage
Interest represented by each affected Class of Certificates then Outstanding,
for the purpose of adding any provisions or changing in any manner or
eliminating any of the provisions of this Agreement or of modifying in any
manner the rights of the Owners hereunder; provided, however, that no such
amendment shall (a) change in any manner the amount of, or change the timing of,
payments which are required to be distributed to any Owner without the consent
of the Owner of such Certificate, (b) reduce the aforesaid percentages of
Percentage Interests which are required to consent to any such amendments or (c)
result in a down-rating or withdrawal of any ratings then assigned to the


                                      109
<PAGE>   115
Offered Certificates, without the consent of the Owners of all Certificates of
the Class or Classes affected then Outstanding.

         (d) Each proposed amendment to this Agreement shall be accompanied by
an opinion of counsel nationally recognized in federal income tax matters
addressed to the Trustee and to the Group I Insurer to the effect that such
amendment would not adversely affect the status of either the Upper-Tier REMIC
or Lower-Tier REMIC as a REMIC. Neither such opinion of counsel nor any expense
of any such proposed amendment shall be at the Trustee's expense.

         (e) The Group I Insurer, the Owners and each Rating Agency shall be
provided with copies of any amendments to this Agreement, together with copies
of any opinions or other documents or instruments executed in connection
therewith.

         SECTION 11.15. REMIC STATUS; TAXES.

         (a) The Tax Matters Person shall prepare and file or cause to be filed
with the Internal Revenue Service Federal tax or information returns with
respect to the Upper-Tier REMIC and Lower-Tier REMIC and the Certificates
containing such information and at the times and in such manner as may be
required by the Code or applicable Treasury regulations, and shall furnish to
Owners such statements or information at the times and in such manner as may be
required thereby. For this purpose, the Tax Matters Person may, but need not,
rely on any proposed regulations of the United States Department of the
Treasury. The Tax Matters Person shall indicate the election to treat each of
the Upper-Tier REMIC and Lower-Tier REMIC as a REMIC (which election shall apply
to the taxable period ending December 31, 1998 and each calendar year
thereafter) in such manner as the Code or applicable Treasury regulations may
prescribe. The Trustee, as Tax Matters Person appointed pursuant to Section
11.17 hereof shall sign all tax information returns filed pursuant to this
Section 11.15. The Tax Matters Person shall provide information necessary for
the computation of tax imposed on the transfer of a Class R Certificate to a
Disqualified Organization, or an agent of a Disqualified Organization, or a
pass-through entity in which a Disqualified Organization is the record holder of
an interest. The Tax Matters Person shall provide the Trustee with copies of any
Federal tax or information returns filed, or caused to be filed, by the Tax
Matters Person with respect to the REMIC Trust or the Certificates.

         (b) The Tax Matters Person shall timely file all reports required to be
filed by the Trust with any federal, state or local governmental authority
having jurisdiction over the Trust, including other reports that must be filed
with the Owners, such as the Internal Revenue Service's Form 1066 and Schedule Q
and the form required under Section 6050K of the Code, if applicable to REMICs.
Furthermore, the Tax Matters Person shall report to Owners, if required, with
respect to the allocation of expenses pursuant to Section 212 of the Code in
accordance with the specific instructions to the Tax Matters Person by the
Sponsor with respect to such allocation of expenses. The Tax Matters Person
shall collect any forms or reports from the Owners determined by the Sponsor to
be required under applicable federal, state and local tax laws.

         (c) The Tax Matters Person shall provide to the Internal Revenue
Service and to persons described in Section 860E(e)(3) and (6) of the Code the
information described in Proposed Treasury Regulation Section
1.860D-1(b)(5)(ii), or any successor regulation thereto. Such information will
be provided in the manner described in Proposed Treasury Regulation Section
1.860E(2)(a)(5), or any successor regulation thereto.


                                      110
<PAGE>   116
         (d) The Sponsor covenants and agrees that within ten Business Days
after receiving a written request from the Trustee it shall provide to the
Trustee any information necessary to enable the Trustee to meet its obligations
under subsections (b) and (c) above.

         (e) The Trustee, the Sponsor and the Master Servicer each covenants and
agrees for the benefit of the Owners (i) to take no action which would result in
the termination of "REMIC" status for the Upper-Tier REMIC and Lower-Tier REMIC,
(ii) not to engage in any "prohibited transaction", as such term is defined in
Section 860F(a)(2) of the Code and (iii) not to engage in any other action which
may result in the imposition on the Upper-Tier REMIC and Lower-Tier REMIC of any
other taxes under the Code.

         (f) The Upper-Tier REMIC and Lower-Tier REMIC shall, for federal income
tax purposes, maintain books on a calendar year basis and report income on an
accrual basis.

         (g) Except as otherwise permitted by Section 7.6(b), no Eligible
Investment shall be sold prior to its stated maturity (unless sold pursuant to a
plan of liquidation in accordance with Article IX hereof).

         (h) Neither the Sponsor nor the Trustee shall enter into any
arrangement by which the Trustee will receive a fee or other compensation for
services rendered pursuant to this Agreement, which fee or other compensation is
paid from the Trust Estate, other than as expressly contemplated by this
Agreement.

         (i) Notwithstanding the foregoing clauses (g) and (h), the Trustee or
the Sponsor may engage in any of the transactions prohibited by such clauses,
provided that the Trustee shall have received the prior written consent of the
Group I Insurer and an opinion of counsel experienced in federal income tax
matters to the effect that such transaction does not result in a tax imposed on
the Trustee or cause a termination of REMIC status for either the Upper-Tier
REMIC or Lower-Tier REMIC; provided, however, that such transaction is otherwise
permitted under this Agreement.

         SECTION 11.16. ADDITIONAL LIMITATION ON ACTION AND IMPOSITION OF TAX.

         (a) Any provision of this Agreement to the contrary notwithstanding,
the Trustee shall not, without having obtained, and delivered to the Group I
Insurer, an opinion of counsel experienced in federal income tax matters (which
opinion shall be at the expense of the Sponsor) to the effect that such
transaction does not result in a tax imposed on the Trust or cause a termination
of REMIC status for either the Upper-Tier REMIC or Lower-Tier REMIC, (i) sell
any assets in the Trust Estate, (ii) accept any contribution of assets after the
Startup Day or (iii) agree to any modification of this Agreement.

         (b) In the event that any tax is imposed on "prohibited transactions"
of either the Upper-Tier REMIC or Lower-Tier REMIC as defined in Section
860F(a)(2) of the Code, on the "net income from foreclosure property" as defined
in Section 860G(c) of the Code, on any contribution to either the Upper-Tier
REMIC or Lower-Tier REMIC after the Startup Day pursuant to Section 860G(d) of
the Code, or any other tax (other than any minimum tax imposed by Sections
23151(a) or 23153(a) of the California Revenue and Taxation Code) is imposed,
such tax shall be paid by (i) the Trustee, if such tax arises out of or results
from a breach by the Trustee of any of its obligations under this Agreement,
(ii) the Master Servicer, if such tax arises out of or results from a breach by
the Master Servicer of any of its obligations under this Agreement, or


                                      111
<PAGE>   117
otherwise (iii) the Owners of the Lower-Tier Residual Class and the Class R
Certificates in proportion to their Percentage Interests. To the extent such tax
is chargeable against the Owners of the Lower-Tier Residual Class and the Class
R Certificates, notwithstanding anything to the contrary contained herein, the
Trustee is hereby authorized to retain from amounts otherwise distributable to
the Owners of the Class R Certificates on any Payment Date sufficient funds to
reimburse the Trustee for the payment of such tax (to the extent that the
Trustee has not been previously reimbursed or indemnified therefor).

         SECTION 11.17. APPOINTMENT OF TAX MATTERS PERSON. The Owners of the
Class R Certificates hereby appoint the Trustee as their agent to act as the Tax
Matters Person for REMIC Trust for all purposes of the Code and such Tax Matters
Person will perform, or cause to be performed, such duties and take, or cause to
be taken, such actions as are required to be performed or taken by the Tax
Matters Person under the Code.

         SECTION 11.18. THE GROUP I INSURER. The Group I Insurer is a
third-party beneficiary of this Agreement. Any right conferred to the Group I
Insurer shall be suspended during any period in which the Group I Insurer is in
default in its payment obligations under the Group I Insurance Policy, except
with respect to amendments to this Agreement pursuant to Section 11.14. During
the continuance of a Group I Insurer Default, the Group I Insurer's rights
hereunder shall vest in the Trustee on behalf of the Owners of the Group II
Certificates and shall be exercisable by the Owners of at least a majority in
Percentage Interest of the Group II Certificates then Outstanding or, if there
are no Group II Certificates then Outstanding and the Group I Insurance Policy
has expired or a Group I Insurer Default has occurred and is continuing, by at
least a majority of the Subordinate Certificates then Outstanding or if there
are no Group II Certificates or Subordinate Certificates outstanding and any and
all amounts due and owing the Group I Insurer under the Insurance Agreement have
been paid in full, and the Group I Insurance Policy has expired or is
unavailable due to a Group I Insurer Default, by at least a majority of the
Class R Certificates then Outstanding. At such time as the Group II Certificates
are no longer Outstanding hereunder and the Group I Insurer has been reimbursed
for all Group II Reimbursement Amounts to which it is entitled hereunder and the
Group I Insurance Policy has expired, the Group I Insurer's rights hereunder
shall terminate.

         SECTION 11.19. MAINTENANCE OF RECORDS. Each Originator and Owner of a

         organized, validly existing and in good standing under the laws
         governing its creation and existence and is in good standing as a

         carry out its business as presently conducted and as proposed to be

         order, rule or regulation of any court, governmental agency or body or
         other tribunal having jurisdiction over such Affiliated Originator or
         any of its properties.

         constitutes a valid, legal and binding obligation of such Affiliated
         Originator, enforceable against it in accordance with the terms hereof,
         except as the enforcement thereof may be limited by applicable
         bankruptcy, insolvency, reorganization, moratorium or other similar

         to any order or decree of any court or any order, regulation or demand
         of any federal, state, municipal or governmental agency, which might
         have consequences that would materially and adversely affect the
         condition (financial or other) or operations of such Affiliated
         Originator or its properties, or might have consequences that would
         materially and adversely affect its performance hereunder and under the
         other Conveyance Agreements to which such Affiliated Originator is a
         party, or which would draw into question the validity of this Agreement
         or the Mortgage Loans taken as a whole or of any action taken or to be
         taken in connection with the obligations of the Affiliated Originator
         contemplated herein.

                  (v) No litigation is pending or, to the best of such
         Affiliated Originator's knowledge, threatened against such Affiliated
         Originator which litigation might have consequences that would prohibit
         its entering into this Agreement or any Conveyance Agreements to which
         it is a party or that would materially and adversely affect the
         condition (financial or otherwise) or operations of such Affiliated

         (administrative, judicial or otherwise) and either the time within
         which any appeal therefrom may be taken or review thereof may be
         obtained has expired or no review thereof may be obtained or appeal
         therefrom taken, and are adequate to authorize the consummation of the
         transactions contemplated by this Agreement and the conveyance
         Agreements on the part of such Affiliated Originator and the
         performance by such Affiliated Originator of its obligations under this
         Agreement and such of the Conveyance Agreements to which it is a party.


                  (x) The origination practices used by such Affiliated

         proper, prudent and customary in the mortgage loan lending business and
         (ii) in compliance with the Servicer's underwriting criteria as
         described in the Prospectus.

                  (xi) The transactions contemplated by this Agreement are in
         the ordinary course of business of such Affiliated Originator. The
         transfer, assignment and conveyance of the Mortgage Notes and the

         any applicable jurisdiction.

                  (xii) Such Affiliated Originator received fair consideration

         interests in the Mortgage Loans.

                  (xiii) Such Affiliated Originator did not sell any interest in
         any Mortgage Loan with any intent to hinder, delay or defraud any of
         its respective creditors.

                  (xiv) Such Affiliated Originator is solvent, and such
         Affiliated Originator will not be rendered insolvent as a result of the
         sale of the Mortgage Loans to the related Advanta Trust.

The representations and warranties set forth in this paragraph (a) shall survive
the sale and assignment of the Mortgage Loans to the Sponsor.

            In addition, each Affiliated Originator hereby covenants to perform
the obligations, if any, imposed upon it by the related Advanta Pooling
Agreement.

         (b) The Sponsor hereby represents and warrants to each Affiliated
Originator and the Trustee that, as of the date hereof:

                  (i) The Sponsor is a corporation duly organized, validly
         existing and in good standing under the laws of the State of Delaware
         and has all licenses and qualifications necessary to carry on its
         business as now being conducted and to perform its obligations
         hereunder; the Sponsor has the power and authority to execute and
         deliver this Agreement and to perform its obligations in accordance
         herewith; the execution, delivery and performance of this Agreement
         (including




                                       6
<PAGE>   9
         any Conveyance Agreement and any other instruments of transfer to be
         delivered pursuant to this Agreement) by the Sponsor and the
         consummation of the transactions contemplated hereby have been duly and
         validly authorized by all necessary corporate action and do not violate
         the organization documents of the Sponsor, contravene or violate any
         law, regulation, rule, order, judgement or decree to which the Sponsor
         or its properties are subject or contravene, violate or result in any
         breach of any provision of, or constitute a default under, or result in
         the imposition of any lien on any assets of the Sponsor pursuant to the
         provisions of, any mortgage, indenture, contract, agreement or other
         undertaking to which the Sponsor is a party or which purports to be
         binding upon Sponsor or any of Sponsor's assets; this Agreement
         evidences the valid and binding obligation of the Sponsor enforceable
         against the Sponsor in accordance with its terms, subject to the effect
         of bankruptcy, insolvency, reorganization, moratorium and other similar
         laws relating to or affecting creditor's rights generally or the
         application of equitable principles in any proceeding, whether at law
         or in equity;

                  (ii) All actions, approvals, consents, waivers, exemptions,
         variances, franchises, orders, permits, authorizations, rights and
         licenses required to be taken, given or obtained, as the case may be,
         by or from any federal, state or other governmental authority or
         agency, that are necessary in connection with the execution and
         delivery by the Sponsor of this Agreement, have been duly taken, given
         or obtained, as the case may be, are in full force and effect, are not
         subject to any pending proceedings or appeals (administrative, judicial
         or otherwise) and either the time within which any appeal therefrom may
         be taken or review thereof may be obtained has expired or no review
         thereof may be obtained or appeal therefrom taken, and are adequate to
         authorize the consummation of the transactions contemplated by this
         Agreement on the part of the Sponsor and the performance by the Sponsor
         of its obligations under this Agreement; and

                  (iii) There is no action, suit, proceeding or investigation
         pending or, to the best of the Sponsor's knowledge, threatened against
         the Sponsor 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 Sponsor or in any
         material impairment of the right or ability of the Sponsor to carry on
         its business substantially as now conducted, or in any material
         liability on the part of the Sponsor or which would draw into question
         the validity of this Agreement or of any action taken or to be taken in
         connection with the obligations of the Sponsor contemplated herein, or
         which would be likely to impair the ability of the Sponsor to perform
         under the terms of this Agreement.

The representations and warranties set forth in this paragraph (b) shall survive
the sale and assignment of the Mortgage Loans to the Sponsor. Upon discovery of
a breach of any of the foregoing representations and warranties which materially
and adversely affects the interests of the Affiliated Originator, the Affiliated
Originator shall give prompt written notice to the Sponsor. Within 30 days of
its receipt of notice of breach, the Sponsor shall cure such breach in all
material respects.

Regarding the Mortgage Loans. (a) Set forth in paragraph (b) below is a listing
of representations and warranties which will be deemed to have been made by each
Affiliated Originator in connection with each conveyance of a Pool from the
Conduit Acquisition Trust to the related Advanta Trust. In addition, a

Pool, delete or modify any of such representations and warranties, or may add
additional representations and warranties ("Additional Representations and
Warranties"). The representations and warranties listed in paragraph (b) below,

         (b) With respect to each Mortgage Loan, each Affiliated Originator
hereby represents, warrants and covenants to the Sponsor and the Trustee, as of
the related Cut-Off Date, as follows, on which representations, warranties and
covenants the Trustee relies in accepting the Mortgage Loans:

                  (i) The information with respect to each Mortgage Loan set
         forth in the Schedules of Mortgage Loans is true and correct as of the
         Cut-Off Date;

                  (ii) All of the original or certified documentation required

         Trustee in accordance with the terms of such Advanta Pooling Agreement.
         Each of the documents and instruments specified to be included therein
         has been duly executed and in due and proper form, and each such
         document or instrument is in a form generally acceptable to prudent
         mortgage lenders that regularly originate or purchase mortgage loans
         comparable to the Mortgage Loans for sale to prudent investors in the
         secondary market that invest in mortgage loans such as the Mortgage
         Loans.

                  (iii) Each Mortgage Loan being transferred to the Sponsor is a
         Qualified Mortgage and is a Mortgage;

                  (iv) Each Property is improved by a single (one-to-four)
         family residential dwelling, which may include manufactured homes which
         qualify as eligible for inclusion in a REMIC, condominiums and
         townhouses but shall not include cooperatives;

                  (v) No Mortgage Loan had a Combined Loan-to-Value Ratio in
         excess of 100%;


                  (vi) Each Mortgage is either a valid and subsisting first,
         second or third lien of record on the Property (subject in the case of
         any Second Mortgage Loan or Third Mortgage Loan only to a Senior Lien
         on such Property) and subject in all cases to the exceptions to title
         set forth in the title insurance policy, with

<PAGE>   11
         respect to the related Mortgage Loan, which exceptions are generally
         acceptable to banking institutions in connection with their regular
         mortgage lending activities, and such other exceptions to which similar
         properties are commonly subject and which do not individually, or in
         the aggregate, materially and adversely affect the benefits of the
         security intended to be provided by such Mortgage;

                  (vii) Immediately prior to the transfer and assignment herein
         contemplated, each Affiliated Originator held good and indefeasible
         title to, and was the sole owner of, each Mortgage Loan conveyed by

         encumbrances or rights of others except liens which will be released
         simultaneously with such transfer and assignment; and immediately upon
         the transfer and assignment herein contemplated, the Trustee will hold
         good and indefeasible title to, and be the sole owner of, each Mortgage
         Loan subject to no liens, charges, mortgages, encumbrances or rights of
         others except liens which will be released simultaneously with such
         transfer and assignment;

                  (viii) As of the related Cut-Off Date, no Mortgage Loan is 30
         or more days Delinquent, except for any portion of the Mortgage Loans
         which the related Advanta Pooling Agreement permits to be more than 30
         days Delinquent;

                  (ix) There is no delinquent tax or assessment lien or
         mechanic's lien on any Property, and each Property is free of
         substantial damage and is in good repair;

                  (x) There is no valid and enforceable right of rescission
         offset, defense or counterclaim to any Note or Mortgage, including the
         obligation of the related Mortgagor to pay the unpaid principal of or
         interest on such Note or 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, counterclaim or defense, including the defense
         of usury, and no such right of rescission, set-off, counterclaim or
         defense has been asserted with respect thereto;

                  (xi) There is no mechanics' lien or claim for work, labor or
         material affecting any Property which is or may be a lien prior to, or
         equal with, the lien of the related Mortgage except those which are
         insured against by any title insurance policy referred to in paragraph
         (xiii) below;

                  (xii) Each Mortgage Loan at the time it was made complied in
         all material respects with all applicable state and federal laws and
         regulations, including, without limitation, the federal
         Truth-in-Lending Act and other consumer protection laws, real estate
         settlement procedure, usury, equal credit opportunity, disclosure and
         recording laws;



                                       9
<PAGE>   12
                  (xiii) With respect to each Mortgage Loan, a lender's title
         insurance policy, issued in standard California Land Title Association
         form or American Land Title Association form, or other form acceptable
         in a particular jurisdiction by a title insurance company authorized to
         transact business in the state in which the related Property is
         situated, in an amount at least equal to the Original Principal Amount
         of such Mortgage Loan insuring the mortgagee's interest under the
         related Mortgage Loan as the holder of a valid first, second or third
         mortgage lien of record on the real property described in the related
         Mortgage, as the case may be, subject only to exceptions of the
         character referred to in paragraph (vi) above, was effective on the
         date of the origination of such Mortgage Loan, and, as of the Cut-Off
         Date such policy will be valid and thereafter such policy shall
         continue in full force and effect;

                  (xiv) The improvements upon each Property are covered by a
         valid and existing hazard insurance policy (which may be a blanket
         policy of the type described in the related Advanta Pooling Agreement)
         with a generally acceptable carrier that provides for fire and extended
         coverage representing coverage not less than the least of (A) the
         outstanding principal balance of the related Mortgage Loan (together,
         in the case of a Second Mortgage Loan, with the outstanding principal
         balance of the Senior Lien), (B) the minimum amount required to
         compensate for damage or loss on a replacement cost basis or (C) the
         full insurable value of the Property;

                  (xv) If the Mortgage Loan at the time of origination relates
         to a Property in an area identified in the Federal Register by the
         Federal Emergency Management Agency as having special flood hazards,
         (which may be a blanket policy of the type described in the related
         Advanta Pooling Agreement) a flood insurance policy in a form meeting
         the requirements of the current guidelines of the Federal Insurance
         Administration with a generally acceptable carrier is in effect with
         respect to such Property in an amount representing coverage, and which
         provides for a recovery by the Master Servicer of insurance proceeds
         relating to such Mortgage Loan of not less than the least of (i) the
         outstanding principal balance of the Mortgage Loan, (ii) the minimum
         amount required to compensate for damage or loss on a replacement cost
         basis and (iii) the maximum amount of insurance that is available under
         the Flood Disaster Protection Act of 1973;

                  (xvi) Each Mortgage and Note is the legal, valid and binding
         obligation of the maker thereof and is enforceable in accordance with
         its terms, except only as such enforcement may be limited by
         bankruptcy, insolvency, reorganization, moratorium or other similar
         laws affecting the enforcement of creditors' rights generally and by
         general principles of equity (whether considered in a proceeding or
         action in equity or at law), and all parties to each Mortgage Loan had
         full legal capacity to execute all documents relating to such Mortgage
         Loan and convey the estate therein purported to be conveyed;

<PAGE>   13
                  (xvii) Each Affiliated Originator has caused and will cause to
         be performed any and all acts required to be performed to preserve the
         rights and remedies of the servicer in any Insurance Policies
         applicable to any Mortgage Loans delivered by such Affiliated
         Originator including, to the extent such Mortgage Loan is not covered
         by a blanket policy described in the Advanta Pooling Agreement, any
         necessary notifications of insurers, assignments of policies or
         interests therein, and establishments of co-insured, joint loss payee
         and mortgagee rights in favor of the servicer;

                  (xviii) Each original Mortgage was recorded or is in the
         process of being recorded, and all subsequent assignments of the
         original Mortgage have been recorded in the appropriate jurisdictions
         wherein such recordation is necessary to perfect the lien thereof for
         the benefit of the applicable Affiliated Originator, subject to the
         provisions of Section 3.5(b) of the Advanta Pooling Agreement, (or are
         in the process of being recorded);

                  (xix) The terms of each Note and each Mortgage have not been
         impaired, altered or modified in any respect, except by a written
         instrument which has been recorded, if necessary, to protect the
         interest of the owners and which has been delivered to the Trustee. The
         substance of any such alteration or modification is reflected on the
         related Schedule of Mortgage Loans and has been approved by the primary
         mortgage guaranty insurer, if any;

                  (xx) The proceeds of each Mortgage Loan have been fully
         disbursed, and there is no obligation on the part of the mortgagee to
         make future advances thereunder. Any and all requirements as to
         completion of any on-site or off-site improvements and as to
         disbursements of any escrow funds therefor have been complied with. All
         costs, fees and expenses incurred in making or closing or recording
         such Mortgage Loans were paid;

                  (xxi) Except as otherwise required by law or pursuant to the
         statute under which the related Mortgage Loan was made, the related
         Note is not and has not been secured by any collateral, pledged account
         or other security except the lien of the corresponding Mortgage;

                  (xxii) No Mortgage Loan was originated under a buydown plan;

                  (xxiii) No Mortgage Loan provides for negative amortization,
         has a shared appreciation feature, or other contingent interest
         feature;

                  (xxiv) Each Property is located in the state identified in the
         Schedule of Mortgage Loans and consists of one or more parcels of real
         property with a residential dwelling erected thereon;

                  (xxv) Each Mortgage contains a provision for the acceleration
         of the payment of the unpaid principal balance of the related Mortgage
         Loan in the event the related Property is sold without the prior
         consent of the mortgagee thereunder;



                                       11
<PAGE>   14
                  (xxvi) Any advances made after the date of origination of a
         Mortgage Loan but prior to the Cut-Off Date, have been consolidated
         with the outstanding principal amount secured by the related Mortgage,
         and the secured principal amount, as consolidated, bears a single
         interest rate and single repayment term reflected on the Schedule of
         Mortgage Loans. The consolidated principal amount does not exceed the
         original principal amount of the related Mortgage Loan. No Note permits
         or obligates the Master Servicer, the Sub-Servicer or the Sponsor to
         make future advances to the related Mortgagor at the option of the
         Mortgagor;

                  (xxvii) There is no proceeding pending or threatened for the
         total or partial condemnation of any Property, nor is such a proceeding
         currently occurring, and each Property is undamaged by waste, fire,
         earthquake or earth movement, flood, tornado or other casualty, so as
         to affect adversely the value of the Property as security for the
         Mortgage Loan or the use for which the premises were intended;

                  (xxviii) All of the improvements which were included for the
         purposes of determining the Appraised Value of any Property lie wholly
         within the boundaries and building restriction lines of such Property,
         and no improvements on adjoining properties encroach upon such
         Property, and, if a title insurance policy exists with respect to such
         Property, are stated in such title insurance policy and affirmatively
         insured;

                  (xxix) No improvement located on or being part of any Property
         is in violation of any applicable zoning law or regulation. All
         inspections, licenses and certificates required to be made or issued
         with respect to all occupied portions of each 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 and such
         Property is lawfully occupied under the applicable law;

                  (xxx) With respect to each Mortgage constituting a deed of
         trust, a trustee, duly qualified under applicable law to serve as such,
         has been properly designated and currently so serves and is named in
         such Mortgage, and no fees or expenses are or will become payable by
         the Sponsor or the related Trust to the trustee under the deed of
         trust, except in connection with a trustee's sale after default by the

         to foreclose the related Mortgage;


                  (xxxiii) Except as provided by clause (viii) of this Section,

         existing under any Mortgage or the related Note and no event which,
         with the passage of time or with notice and the expiration of any grace
         or cure period, would constitute a default, breach, violation or event
         of acceleration; and the applicable Affiliated Originator has not
         waived any default, breach, violation or event of acceleration;

         Loan, and no Mortgagor has been released, in whole or in part, except
         in connection with an assumption agreement which has been approved by
         the primary mortgage guaranty insurer, if any, and which has been
         delivered to the Trustee;

                  (xxxv) Except for any Bulk Acquisition Loan, the maturity date
         of each Mortgage Loan which is a Second Mortgage Loan or a Third
         Mortgage Loan is at least twelve months prior to the maturity date of
         the related first mortgage loan if such first mortgage loan provides
         for a balloon payment;

                  (xxxvi) The credit underwriting guidelines applicable to each
         Mortgage Loan which is not a Bulk Acquisition Loan or an Unaffiliated
         Originator Loan conform in all material respects to the Sponsor's
         underwriting guidelines;

                  (xxxvii) All parties to the Note and the Mortgage had legal
         capacity to execute the Note and the Mortgage and each Note and
         Mortgage have been duly and properly executed by such parties; and

                  (xxxviii) The related Affiliated Originator has no actual
         knowledge that there exist on any Property any hazardous substances,
         hazardous wastes or solid wastes, as such terms are defined in the
         Comprehensive Environmental Response Compensation and Liability Act,
         the Resource Conservation and Recovery Act of 1976, or other federal,
         state or local environmental legislation.

         (c) No Originator Payment Obligations. There is no obligation on the
part of the Servicer or any other party to make payments in addition to those
made by the Mortgagor except for delinquency.

         The Representations and Warranties shall survive the transfer and
assignment of the Mortgage Loans to the related Advanta Trust. Upon discovery by
the Affiliated Originator or the Sponsor of a breach of any of the
Representations and Warranties, without regard to any limitation set forth in

be made regardless of any acceleration of the Obligations, unless such
acceleration is at the sole option of the Certificate Insurer.

for withholding taxes, if any (including interest and penalties in respect of

Insurer, irrevocably assigning to the Certificate Insurer all rights and claims

payment and (iv) appropriate instruments to effect the appointment of the
<PAGE>   2

such preference payment, such instruments being in a form satisfactory to the
Certificate 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 Certificate Insurer will pay any other amount payable hereunder no
later than 12:00 noon New York City time on the later of the Payment Date on
which the related Deficiency Amount is due or the third Business Day following

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 Certificate Insurer or the
Fiscal Agent, as the case may be, shall promptly so advise the Trustee and the
Trustee may submit an amended Notice.

held by the Trustee for the payment of such Insured Payment and legally
available therefor.

                  &  Co.   Incorporated   (the   "Representative")   and
                  Indemnification  Agreement  dated as of March 12, 1998
                  (the    "Indemnification    Agreement")   among   MBIA
                  Insurance  Corporation  (the  "Insurer"),  Advanta and
                  the Representative
                  -------------------------------------------------------

Ladies and Gentlemen:

            Pursuant to the Underwriting Agreement and the Indemnification
Agreement (together, the "Designated Agreements"), Advanta has undertaken
certain financial obligations with respect to the indemnification of the
Underwriters and the Insurer with respect to the Registration Statement, the
Prospectus and the Prospectus Supplement described in the Designated Agreements.
Any financial obligations of Advanta under the Designated Agreements, whether or
not specifically enumerated in this paragraph, are hereinafter referred to as
the "Joint and Several Obligations"; provided, however, the "Joint and Several
Obligations" shall mean only the financial obligations of Advanta under the
Designated Agreements (including the payment of money damages for a breach of
any of Advanta's obligations under the Designated Agreement, whether financial
or otherwise) but shall not include any obligations not relating to the payment
of money.

            As a condition of their respective executions of the Underwriting
Agreement and of the Indemnification Agreement, the Underwriters and the Insurer
have required the undersigned, Advanta Mortgage Holding Company ("AMHC"), the
parent corporation of Advanta, to acknowledge its joint-and-several liability
with Advanta for the payment of the Joint and Several Obligations under the
Designated Agreements. Now, therefore, the Underwriters, the Insurer and AMHC do
hereby agree that:

         (i)      AMHC hereby agrees to be absolutely and unconditionally
                  jointly and severally liable with Advanta to the Underwriters
                  for the
<PAGE>   2
                  payment of the Joint and Several Obligations under the
                  Underwriting Agreement.

        (ii)      AMHC hereby agrees to be absolutely and unconditionally
                  jointly and severally liable with Advanta to the Insurer for
                  the payment of the Joint and Several Obligations under the
                  Indemnification
                  Agreement.

       (iii)      AMHC may honor its obligations hereunder either by direct
                  payment of any Joint and Several Obligations or by causing any
                  Joint and Several Obligations to be paid to the Underwriters
                  by Advanta or another affiliate of AMHC.


            Capitalized terms used herein and not defined herein shall have
their respective meanings set forth in the Agreement.

                                    Very truly yours,

The Certificate Insurer represents and warrants to the Underwriters and the
Sponsor as follows:

            (a) Organization and Licensing. The Certificate Insurer is a duly
      incorporated and existing New York stock insurance company licensed to do
      business in the State of New York.

            (b) Corporate Power. The Certificate Insurer has the corporate power
      and authority to issue the Policies and to execute and deliver this
      Agreement and the Insurance Agreement and to perform all of its
      obligations hereunder and thereunder.

            (c) Authorization; Approvals. The issuance of the Policies and the
      execution, delivery and performance of this Agreement and the Insurance
      Agreement have been duly authorized by all necessary corporate
      proceedings. No further approvals or filings of any kind, including,
      without limitation, any further approvals of or further filings with any
      governmental agency or other governmental authority, or any approval of
      the Insurer's board of directors or stockholders, are necessary for the
      Policies, this Agreement and the Insurance Agreement to constitute the
      legal, valid and binding obligations of the Certificate Insurer.

            (d) Enforceability. The Policies, when issued, and this Agreement
      and the Insurance Agreement will each constitute a legal, valid and
      binding obligation of the Certificate Insurer, enforceable in accordance
      with its terms, subject to applicable laws affecting the enforceability of
      creditors' rights generally.

            (e) Financial Information. The consolidated financial statements of
      the Certificate Insurer as of December 31, 1996 and December 31, 1995 and
      for the three years ended December 31, 1996 incorporated by reference in
      the Prospectus Supplement (the "Certificate Insurer Audited Financial
      Statements"), fairly present in all material respects the financial
      condition of the Certificate Insurer as of such date and for the period
      covered by such statements in accordance with generally accepted
      accounting principles consistently applied. The consolidated financial
      statements of the Certificate Insurer and its subsidiaries for the nine
      months ended September 30, 1997 incorporated by reference in the
      Prospectus Supplement (the "Certificate Insurer Unaudited Financial
      Statements") fairly present in all material respects the financial
      condition of the Certificate Insurer as of such date and for the period
      covered by such statements in accordance with generally accepted
      accounting principles applied in a manner consistent with the accounting
      principles used in preparing the Certificate Insurer Audited Financial
      Statements, and, since September 30, 1997, there has been no material
      change in such financial condition of the Certificate Insurer which would
      materially and adversely affect its ability to perform its obligations
      under the Policy.


                                       3
<PAGE>   6
            (f) Certificate Insurer Information. The information in the
      Prospectus Supplement as of the date hereof under the captions "THE GROUP
      I INSURER" and "THE GROUP I INSURANCE POLICY" (the "Insurer Information")
      is true and correct in all material respects and does not contain any
      untrue statement of a fact that is material to the Certificate Insurer's
      ability to perform its obligations under the Policy.

            (g) No Litigation. There are no actions, suits, proceedings or
      investigations pending or, to the best of the Certificate Insurer's
      knowledge, threatened against it at law or in equity or before or by any
      court, governmental agency, board or commission or any arbitrator which,
      if decided adversely, would materially and adversely affect its condition
      (financial or otherwise) or operations or which would materially and
      adversely affect its ability to perform its obligations under this
      Agreement, the Policy or the Insurance Agreement.

      Section 3. AGREEMENTS, REPRESENTATIONS AND WARRANTIES OF THE UNDERWRITERS.
Each Underwriter represents and warrants to and agrees with the Sponsor and the
Insurer that the statements in the Prospectus Supplement made in reliance upon
and in conformity with written information relating to such Underwriter
furnished to the Sponsor specifically for use in the preparation of the
Prospectus Supplement, and acknowledged in writing as described in Section
VIII.H of the Underwriting Agreement (referred to herein as the "Underwriter
Information"), are true and correct in all material respects.

      Section 4.  AGREEMENTS, REPRESENTATIONS AND WARRANTIES OF THE SPONSOR.
The Sponsor represents and warrants to and agrees with the Certificate
Insurer and the Underwriters as follows:

            (a) Registration Statement. The information in the Registration
      Statement, the Prospectus and the Prospectus Supplement, other than the
      Insurer Information, is true and correct in all material respects and does
      not contain any untrue statement of a fact that is material or omit to
      state a fact necessary to make the statements therein, in light of the
      circumstances under which they were made, not misleading.

            (b) Organization. The Sponsor is duly incorporated and existing
      under the laws of the State of Delaware and is in good standing as a
      foreign corporation in each jurisdiction in which the nature of its
      business, or the properties owned or leased by it, makes such
      qualification necessary.

            (c) Corporate Power. The Sponsor has the corporate power and
      authority to execute and deliver this Agreement, the Underwriting
      Agreement, the Pooling and Servicing Agreement, the Master Transfer
      Agreements and the Insurance Agreement and to perform all of its
      obligations hereunder and thereunder.

            (d) Authorization; Approvals. The execution, delivery and
      performance of this Agreement, the Underwriting Agreement, the Master
      Transfer Agreements, the Pooling and Servicing Agreement and the Insurance
      Agreement by the Sponsor have been duly authorized by all necessary
      corporate proceedings. No further approvals or filings of any kind,
      including, without limitation, any further approvals of or further filing
      with any


                                       4
<PAGE>   7
      governmental agency or other governmental authority, or any approval of
      the Sponsor's board of directors or stockholders, are necessary for this
      Agreement, the Underwriting Agreement, the Pooling and Servicing Agreement
      and the Insurance Agreement to constitute the legal, valid and binding
      obligations of the Sponsor.

            (e) Enforceability. This Agreement, the Pooling and Servicing
      Agreement, the Master Transfer Agreements, the Underwriting Agreement and
      the Insurance Agreement will each constitute a legal, valid and binding
      obligation of the Sponsor, each enforceable in accordance with its terms,
      subject, as to the enforcement of remedies, to bankruptcy, insolvency,
      reorganization, moratorium and other similar laws affecting the
      enforceability of creditors' rights generally applicable in the event of
      the bankruptcy, insolvency or reorganization of the Sponsor and to general
      principles of equity.

            (f) No Litigation. There are no actions, suits, proceedings or
      investigations pending or, to the best of the Sponsor's knowledge,
      threatened against it at law or in equity or before any court,
      governmental agency, board or commission or any arbitrator which, if
      decided adversely, would materially and adversely affect its condition
      (financial or otherwise) or operations of it or would materially and
      adversely affect its ability to perform its obligations under this
      Agreement, the Underwriting Agreement, the Master Transfer Agreements, the
      Pooling and Servicing Agreement or the Insurance Agreement.

      Section 5. INDEMNIFICATION. (a) The Certificate Insurer hereby agrees,
upon the terms and subject to the conditions of this Agreement, to indemnify,
defend and hold harmless each Sponsor Party and each Underwriter Party against
any and all Losses incurred by them with respect to the offer and sale of any of
the Insured Certificates and resulting from the Certificate Insurer's breach of
any of its representations and warranties set forth in Section 2 of this
Agreement.

      (b) Each Underwriter hereby agrees, upon the terms and subject to the
conditions of this Agreement, to indemnify, defend and hold harmless each
Insurer Party against any and all Losses incurred by it with respect to the
offer and sale of any of the Offered Certificates and resulting from such
Underwriter's breach of any of its representations and warranties set forth in
Section 3 of this Agreement.

      (c) The Sponsor hereby agrees, upon the terms and subject to the
conditions of this Agreement, to indemnify, defend and hold harmless each
Insurer Party against any and all Losses incurred by it with respect to the
offer and sale of any of the Offered Certificates and resulting from the
Sponsor's breach of any of its representations and warranties set forth in
Section 4 of this Agreement.

      (d) Upon the incurrence of any Losses entitled to indemnification
hereunder, the Indemnifying Party shall reimburse the Indemnified Party promptly
upon establishment by the Indemnified Party to the Indemnifying Party of the
Losses incurred.

      Section 6. NOTICE TO BE GIVEN. (a) Except as provided in Section 7 below
with respect to contribution, the indemnification provided herein by the
Indemnifying Party shall be the exclusive remedy of each Indemnified Party for
the Losses resulting from the Indemnifying


                                       5
<PAGE>   8
Party's breach of a representation, warranty or agreement hereunder; provided,
however, that each Indemnified Party shall be entitled to pursue any other
remedy at law or in equity for any such breach so long as the damages sought to
be recovered shall not exceed the Losses incurred thereby resulting from such
breach.

      (b) In the event that any action or regulatory proceeding shall be
commenced or claim asserted which may entitle an Indemnified Party to be
indemnified under this Agreement, such party shall give the Indemnifying Party
written or facsimile notice of such action or claim reasonably promptly after
receipt of written notice thereof.

      (c) Upon request of the Indemnified Party, the Indemnifying Party shall
retain counsel reasonably satisfactory to the Indemnified Party to represent the
Indemnified Party and any others the Indemnifying Party may designate in such
proceeding and shall pay the fees and disbursements of such counsel related to
such proceeding. The Indemnifying Party may, at its option, at any time upon
written notice to the Indemnified Party, assume the defense of any proceeding
and may designate counsel reasonably satisfactory to the Indemnified Party in
connection therewith provided that the counsel so designated would have no
actual or potential conflict of interest in connection with such representation.
Unless it shall assume the defense of any proceeding, the Indemnifying Party
shall not be liable for any settlement of any proceeding, effected without its
written consent, but if settled with such consent or if there be a final
judgment for the plaintiff, the Indemnifying Party agrees to indemnify the
Indemnified Party from and against any loss or liability by reason of such
settlement or judgment. The Indemnifying Party shall be entitled to participate
in the defense of any such action or claim in reasonable cooperation with, and
with the reasonable cooperation of, each Indemnified Party.

      (d) The Indemnified Party will have the right to employ its own counsel in
any such action, but the fees and expenses of such counsel will be at the
expense of such Indemnified Party unless (1) the employment of counsel by the
Indemnified Party at the Indemnifying Party's expense has been authorized in
writing by the Indemnifying Party, (2) the Indemnifying Party has not in fact
employed counsel to assume the defense of such action within a reasonable time
after receiving notice of the commencement of the action or (3) the named
parties to any such action include the Indemnifying Party on the one hand and,
on the other hand, the Indemnified Party, and representation of both parties by
the same counsel would be inappropriate due to actual or potential differing
interests between them (in which case, if such Indemnified Party notifies the
Indemnifying Party in writing that it elects to employ separate counsel at the
expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense of such action or proceeding on such Indemnified
Party's behalf), in each of which cases the reasonable fees and expenses of
counsel (including local counsel) will be at the expense of the Indemnifying
Party, and all such fees and expenses will be reimbursed promptly as they are
incurred. In the event that any expenses so paid by the Indemnifying Party are
subsequently determined to not be required to be borne by the Indemnifying Party
hereunder, the party which received such payment shall promptly refund to the
Indemnifying Party the amount so paid by such Indemnifying Party.
Notwithstanding the foregoing, in connection with any one action or separate but
substantially similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances, the Indemnifying Party shall not
be liable for the fees


                                       6
<PAGE>   9
and expenses of more than one counsel for all Seller Parties, more than one
counsel for all Underwriters Parties and more than one counsel for all Insurer
Parties, as applicable.

      (e) The Indemnified Parties shall cooperate with the Indemnifying Parties
in resolving any event which would give rise to an indemnity obligation pursuant
to Section 5 hereof in the most efficient manner.

      (f) No settlement of any such claim or action shall be entered into
without the consent of each Indemnified Party who is subject to such claim or
action, on the one hand, and each Indemnifying Party who is subject to such
claim or action, on the other hand; provided, however, that the consent of such
Indemnified Party shall not be required if such settlement fully discharges,
with prejudice against the plaintiff, the claim or action against such
Indemnified Party.

      (g) Any failure by an Indemnified Party to comply with the provisions of
this Section shall relieve the Indemnifying Party of liability only if such
failure is materially prejudicial to any legal pleadings, grounds, defenses or
remedies in respect thereof or the Indemnifying Party's financial liability
hereunder, and then only to the extent of such prejudice.

      Section 7. CONTRIBUTION. (a) To provide for just and equitable
contribution if the indemnification provided by the Certificate Insurer is
determined to be unavailable for any Underwriter Party or Sponsor Party (other
than pursuant to Section 5 or 6 of this Agreement), the Certificate Insurer
shall contribute to the aggregate costs of liabilities arising from any breach
of a representation or warranty set forth in this Agreement on the basis of the
relative fault of all Underwriter Parties, all Sponsor Parties and all Insurer
Parties, respectively.

      (b) To provide for just and equitable contribution if the indemnification
provided by the Sponsor is determined to be unavailable for any Insurer Party
(other than pursuant to Section 5 or 6 of this Agreement), the Sponsor shall
contribute to the aggregate costs of liabilities arising from any breach of a
representation or warranty set forth in this Agreement on the basis of the
relative fault of all Underwriter Parties, all Sponsor Parties and all Insurer
Parties.

      (c) To provide for just and equitable contribution if the indemnification
provided by each Underwriter is determined to be unavailable for any Insurer
Party (other than pursuant to Section 5 or 6 of this Agreement), such
Underwriter shall contribute to the aggregate costs of liabilities arising from
any breach of a representation or warranty set forth in this Agreement on the
basis of the relative fault of all Underwriter Parties, all Sponsor Parties and
all Insurer Parties. In no case shall any Underwriter be responsible for any
amount in excess of the Underwriting discount applicable to the Certificates
purchased by such Underwriters pursuant to the Underwriting Agreement.

      (d) The relative fault of each Indemnifying Party, on the one hand, and of
each Indemnified Party, on the other hand, shall be determined by reference to,
among other things, whether the breach of, or alleged breach of, any of its
representations and warranties set forth in Section 2, 3 or 4 of this Agreement
relates to information supplied by, or action within the control


                                       7
<PAGE>   10
of, the Indemnifying Party or the Indemnified Party and the Parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such breach.

      (e) The Parties agree that the Certificate Insurer shall be solely
responsible for the Insurer Information and for the Insurer Financial
Statements, that each Underwriter shall be solely responsible for the
Underwriter Information provided by such Underwriter in writing for use in the
Prospectus Supplement and that the Sponsor shall be responsible for all other
information in the Registration Statement and the Prospectus Supplement.

      (f) No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

      (g) The indemnity and contribution agreements contained in this Agreement
shall remain operative and in full force and effect, regardless of (i) any
investigation made by or on behalf of any Underwriter Party, any Sponsor Party
or any Insurer Party, (ii) the issuance of any Offered Certificates or the
Policy or (iii) any termination of this Agreement.

      (h) Upon the incurrence of any Losses entitled to contribution hereunder,
the contributor shall reimburse the party entitled to contribution promptly upon
establishment by the party entitled to contribution to the contributor of the
Losses incurred.

      Section 8. NOTICES. All notices and other communications provided for
