Item 2.  Acquisition or Disposition of Assets


Description of the Certificates and the Mortgage Loans

                  Advanta Mortgage Conduit Services, Inc. registered an issuance
of $2,200,000,000 in principal amount of Mortgage Loan Asset-Backed Certificates
on a delayed or continuous basis pursuant to Rule 215 under the Securities Act
of 1933, as amended (the "Act"), by the Registration Statement on Form S-3 (File
No. 333-21265) (the "Registration Statement"). Pursuant to the Registration
Statement, Advanta Mortgage Loan Trust 1997-2 (the "Registrant" or the "Trust")
issued approximately $900,000,000 in aggregate principal amount of its Mortgage
Loan Asset-Backed Certificates, Series 1997-3 (the "Certificates"), on September
18, 1997 (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 September 1, 1997, between 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
fourteen 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-5 Group I
Certificates, the Class A-6 Group I Certificates, the Class A-7 Group I
Certificates, the Class A-IO Group I Certificates, the Class A-8 Group II
Certificates, the Class A-9 Group II Certificates (collectively, the "Class A
Certificates"), the Class A-1 Group I Certificates, the Class M-2 Group I
Certificates (together, the "Mezzanine Certificates"), the Class B-1 Group I
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.

                  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-8 and Class A-9 Certificates) and the Subordinate 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 Class A-8 and Class A-9 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.

                  qualification, and has all power and authority necessary to
                  own or hold its properties, to conduct the business in which
                  it is engaged and to enter into and perform its obligations

                  Agreement, the Indemnification Agreement, the Purchase
                  Agreement or this Agreement, as the case may be, or (d) which

                  of any order preventing or suspending the use of any
                  Preliminary Prospectus or the Prospectus or suspending any
                  such qualification, the Company promptly shall use its best

                  amendment thereto filed with the Commission, including all
                  consents and exhibits filed therewith.

                  Certificates, and if at such time any events shall have
                  occurred as a result of which the Prospectus as then amended
                  or supplemented would include any untrue statement of a
                  material fact or omit to state any material fact necessary in
                  order to make the statements therein, in the light of the
                  circumstances under which they were made when such Prospectus
                  is delivered, not misleading, or, if for any other reason it
                  shall be necessary during such same period to amend or
                  supplement the Prospectus or to file under the Exchange Act
                  any document incorporated by reference in the Prospectus in

                  or a supplement to the Prospectus which corrects such
                  statement or omission or effects such compliance, and in case
                  any of the Underwriters are required to deliver a Prospectus

                  to the Registration Statement or the Prospectus or any
                  supplement to the Prospectus that may, in the judgment of the
                  Company or the Representative, be required by the Securities
                  Act or requested by the Commission.

                           E. Prior to filing with the Commission any (i)

                  qualifications in effect for as long as may be required for
                  the distribution of the Offered Certificates. The Company will

                  be required by the laws of each jurisdiction in which the
                  Offered Certificates have been so qualified.

                           H. Not, without the Representative's prior written
                  consent, to publicly offer or sell or contract to sell any

                  to the public.

                  outstanding, to deliver to the Representative as soon as such
                  statements are furnished to the Trustee: (i) the annual

obligations of the Underwriters to purchase the Offered Certificates pursuant to
this Agreement are subject to: (i) the accuracy on and as of the Closing Date of
the representations and warranties on the part of the Company herein contained;
(ii) the performance by the Company of all of their respective obligations
hereunder; and (iii) the following conditions as of the Closing Date:

                           A. The Representative shall have received
                  confirmation of the effectiveness of the Registration
                  Statement. No stop order suspending the effectiveness of the
                  Registration Statement or any part thereof shall have been
                  issued and no proceeding for that purpose shall have been
                  initiated or threatened by the Commission. Any request of the
                  Commission for inclusion of additional information in the
                  Registration Statement or the Prospectus shall have been
                  complied with.

                           B. None of the Underwriters shall have discovered and
                  disclosed to the Company on or prior to the Closing Date that
                  the Registration Statement or the Prospectus or any amendment
                  or supplement thereto contains an untrue statement of a fact
                  or omits to state a fact which, in the opinion of Dewey
                  Ballantine, counsel for the Underwriters, is material and is
                  required to be stated therein or is necessary to make the
                  statements therein not misleading.

                           C. All corporate proceedings and other legal matters
                  relating to the authorization, form and validity of this
                  Agreement, the Pooling and Servicing Agreement, the Purchase
                  Agreement, the 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 

                                       9
<PAGE>   11
                  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, 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
                  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.

                                       10
<PAGE>   12
                           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.

                           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 

                                       11

                  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 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 

                                       12
<PAGE>   14
                  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;

                           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 June 30, 1997, and no such amendment has been
                  authorized. No event has occurred since June 30, 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 June 30, 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.

                                       13

                  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 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 

                                       14

                  or representative, and the signatures of such persons
                  appearing on such documents are their genuine signatures.

                           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 New York. 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 in the Prospectus
                  Supplement under the captions "CREDIT ENHANCEMENT", "THE CLASS
                  A-8 AND CLASS A-9 INSURER" and "THE CLASS A-8 AND CLASS A-9
                  INSURANCE POLICY" 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, 1996, 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;

                           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
                  Supplement under the captions "CREDIT ENHANCEMENT", "THE CLASS
                  A-8 and CLASS A-9 INSURER" and "THE CLASS A-8 and CLASS A-9
                  INSURANCE POLICY" 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 caption "THE CLASS A-8 and CLASS A-9
                  INSURER" presents fairly the capitalization of the Insurer as
                  of June 30, 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, 1996 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; the
                  unaudited balance sheet of the Insurer as of June 30, 1997 and
                  the related statement of income and retained earnings for the
                  three-month period then ended, copies of which are included 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
                  applied consistently with those principles applied in
                  preparing the December 31, 1996 audited statements.

                           7. to the best knowledge of such officer, since June
                  30, 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.

                  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, 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, 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.

<PAGE>   19
                           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 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

all as provided in this Agreement; (d) the costs of reproducing and distributing
this Agreement; (e) the fees and expenses of qualifying the Offered Certificates

the Underwriters); (f) any fees charged by securities rating services for rating
the Offered Certificates; (g) half of the costs and expenses of Dewey

Section VII, the Underwriters shall pay their own costs and expenses, including
half of the costs and expenses of Dewey Ballantine, 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, 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 Information) furnished to the Company through
the Representative specifically for inclusion therein unless such untrue
statement or alleged untrue statement or omission or alleged omission was
derived from an inaccuracy or omission in the Company-Provided Information; 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

                                       19
<PAGE>   21
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 (excluding any Derived Information which is covered in paragraph (E)
below) 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 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 

                                       20
<PAGE>   22
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
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 a copy of
its Derived Information no later than one business day prior to the date such
information is required to be filed, pursuant to the No-Action Letters (as
defined herein), 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 

                                       21
<PAGE>   23
the Derived Information provided by such Underwriter, or arise out of or are
based upon the omission or alleged omission to state therein, when read in
conjunction with the Prospectus, 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.

                  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 loss, claim, damage or liability, or action in respect thereof,
as well as any other relevant equitable considerations.

                                       22
<PAGE>   24
                  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.

                  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
agreements hereunder shall be in writing, and:

                           A. if to the Underwriters, shall be delivered or sent
                  by mail, telex or facsimile transmission to Lehman Brothers

                  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 the representations, warranties, indemnities and agreements
contained in this Agreement shall also be deemed to be for the benefit of the
person or persons, if any, who control the Underwriters within the meaning of
Section 15 of the Securities Act, and for the benefit of directors of the
Company, officers of the 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.

                  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

                  SECTION XVIII Headings. The headings herein are inserted for

                            As of September __, 1997

Lehman Brothers Inc.
As Representative of the Underwriters
named in Schedule I

     Re:     Underwriting Agreement dated September ___, 1997 (the
             "Underwriting Agreement") between Advanta Mortgage Conduit
             Services, Inc. ("Advanta") and Lehman Brothers Inc. (the
             "Representative") and Indemnification Agreement dated as of
             September ___, 1997 (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, that "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 Agreements, 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 payment of the
                           Joint and Several Obligations under the Underwriting
                           Agreement.

                  (ii)     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.

equivalent value in exchange for the sale of the interests in the Mortgage Loans
evidenced by the Certificates.

            (k) The Sponsor did not sell any interest in any Mortgage Loan

its respective creditors.

            (l) The Sponsor is solvent and the Sponsor will not be rendered

of the Certificates.

            It is understood and agreed that the representations and warranties

            SECTION 3.2. REPRESENTATIONS AND WARRANTIES OF THE MASTER SERVICER.
The Master Servicer hereby represents, warrants and covenants to the Trustee,
the Class A-8 and Class A-9 Certificate Insurer and to the Owners as of the

            (a) The Master Servicer is a corporation duly organized, validly
existing and in good standing under the laws of the State of Delaware, is, and
each Sub-Servicer is, in compliance with the laws of each state in which any
Property is located to the extent necessary to enable it to perform its
obligations hereunder 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 make such qualification necessary. The Master Servicer and each
Sub-servicer has all requisite corporate power and authority to own and operate
its properties, to carry out its business as presently conducted and as proposed
to be conducted and to enter into and discharge its obligations under this
Agreement and the other Operative Documents to which it is a party. The Master

$5,000,000, as determined in accordance with generally accepted accounting
principles.

            (b) The execution and delivery of this Agreement by the Master
Servicer and its performance and compliance with the terms of this Agreement and
the other Operative


                                       47
<PAGE>   61
Documents to which it is a party have been duly authorized by all necessary
corporate action on the part of the Master Servicer and will not violate the
Master Servicer's Articles of Incorporation or Bylaws or constitute a default
(or an event which, with notice or lapse of time, or both, would constitute a
default) under, or result in the breach of, any material contract, agreement or
other instrument to which the Master Servicer is a party or by which the Master
Servicer is bound or violate any statute or any order, rule or regulation of any
court, governmental agency or body or other tribunal having jurisdiction over
the Master Servicer or any of its properties.

            (c) This Agreement and the other Operative Documents to which the
Master Servicer is a party, assuming due authorization, execution and delivery
by the other parties hereto and thereto, each constitutes a valid, legal and
binding obligation of the Master Servicer, enforceable against it in accordance
with the terms hereof, except as the enforcement hereof may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or other similar
laws affecting creditors' rights generally and by general principles of equity
(whether considered in a proceeding or action in equity or at law).

            (d) The Master Servicer is not in default with respect to any order
or decree of any court or any order, regulation or demand of any federal, state,
municipal or governmental agency, which might have consequences that would
materially and adversely affect the condition (financial or other) or operations
of the Master Servicer or its properties or might have consequences that would
materially and adversely affect its performance hereunder and under the other
Operative Documents to which the Master Servicer is a party.

            (e) No litigation is pending or, to the best of the Master
Servicer's knowledge, threatened against the Master Servicer which litigation
might have consequences that would prohibit its entering into this Agreement or
any other Operative Document to which it is a party or that would materially and
adversely affect the condition (financial or otherwise) or operations of the
Master Servicer or its properties or might have consequences that would
materially and adversely affect its performance hereunder and under the other
Operative Documents to which the Master Servicer is a party.

            (f) No certificate of an officer, statement furnished in writing or
report delivered pursuant to the terms hereof by the Master Servicer contains
any untrue statement of a material fact or omits to state any material fact
necessary to make the certificate, statement or report not misleading.

            (g) The statements contained in the Registration Statement which
describe the Master Servicer or matters or activities for which the Master
Servicer is responsible in accordance with the Operative Documents or which are
attributed to the Master Servicer therein are true and correct in all material
respects, and the Registration Statement does not contain any untrue statement
of a material fact with respect to the Master Servicer or omit to state a
material fact required to be stated therein or necessary to make the statements
contained therein with respect to the Master Servicer not misleading. To the
best of the Master Servicer's knowledge and belief, the Registration Statement
does not contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements

            (h) The Servicing Fee is a "current (normal) servicing fee rate" as
that term is used in Statement of Financial Accounting Standards No. 65 issued
by the Financial Accounting Standards Board. Neither the Master Servicer nor any
affiliate thereof will report on any financial statements any part of the
Servicing Fee as an adjustment to the sales price of the Mortgage Loans.

            (i) 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 (other than any such
actions, approvals, etc. under any state securities laws, real estate
syndication or "Blue Sky" statutes, as to which the Master Servicer makes no
such representation or warranty), that are necessary or advisable in connection
with the execution and delivery by the Master Servicer of the Operative
Documents to which it is a party, have been duly taken, given or obtained, as
the case may be, are in full force and effect on the date hereof, 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 and the other Operative Documents on
the part of the Master Servicer and the performance by the Master Servicer of
its obligations under this Agreement and such of the other Operative Documents
to which it is a party.

            (j) The collection practices used by the Master Servicer with
respect to the Mortgage Loans directly serviced by it have been, in all material
respects, legal, proper, prudent and customary in the mortgage loan servicing
business.

            (k) The transactions contemplated by this Agreement are in the
ordinary course of business of the Master Servicer.

            (l) The terms of each existing Sub-Servicing Agreement and each
designated Sub-servicer are acceptable to the Master Servicer and any new
Sub-Servicing Agreements or Sub-servicers will comply with the provisions of
Section 8.3.

            It is understood and agreed that the representations and warranties
set forth in this Section 3.2 shall survive delivery of the Mortgage Loans to
the Trustee.

            Upon discovery by any of the Originators, the Master Servicer, the
Sponsor, any Sub-Servicer, the Class A-8 and Class A-9 Certificate Insurer or
the Trustee of a breach of any of the representations and warranties set forth
in this Section 3.2 which materially and adversely affects the interests of the
Owners or of the Class A-8 and Class A-9 Certificate Insurer, the party
discovering such breach shall give prompt written notice to the other parties.
Within 30 days of its discovery or its receipt of notice of breach, the Master
Servicer shall cure such breach in all material respects and, upon the Master
Servicer's continued failure to cure such breach, may thereafter be removed by
the Trustee or the Class A-8 and Class A-9 Certificate Insurer pursuant to
Section 8.20 hereof; provided, however, that if the Master Servicer can
demonstrate to the reasonable satisfaction of the Class A-8 and Class A-9
Certificate Insurer and the Trustee that it is diligently pursuing remedial
action, then the cure period may be extended with the written approval of the
Class A-8 and Class A-9 Certificate 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 Class A-8
and Class A-9 Certificate 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 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:

                  (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 set forth
      in Section 3.5 (including all material documents related thereto) with
      respect to each Mortgage Loan has been or will be delivered to the Trustee
      on the Startup Day, or as otherwise provided in Section 3.5;

                  (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 7.0% per annum;

                  (v) As of the Cut-Off Date, no more than 0.48% of the Original
      Pool Balance of the Mortgage Loans are 30-59 days Delinquent and no
      Mortgage Loan is 60 or more days' Delinquent;

                  (vi) As of the Startup Day, no more than 1.58% of the Original
      Pool Balance of the Mortgage Loans is secured by Properties located within
      any single zip code area, and no more than 9.60% of the Original Pool
      Balance of the Mortgage Loans consists of Date-of-Payment 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;

                  (viii) Except for the Bulk Acquisition Loans and any
      Unaffiliated Originator Loans, as of the Cut-Off Date, no more than 6.50%
      of the Loan Balance of the Mortgage Loans relates to Mortgage Loans
      originated under the Originators' non-income verification program for
      self-employed borrowers; and

                  (ix) 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 Class A-8 and Class A-9 Certificate Insurer
(so long as a Class A-8 and Class A-9 Certificate Insurer Default had not
occurred and is continuing) all of its right, title and


                                       50
<PAGE>   64
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 Class
A-8 and Class A-9 Certificate Insurer. Upon the discovery by the Sponsor, the
Master Servicer, the Class A-8 and Class A-9 Certificate 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 Class A-8 and Class A-9
Certificate 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 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 Class A-8 and Class A-9
Certificate 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 Class A-8 and Class A-9 Certificate
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 Class A-8 and Class A-9 Certificate 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
Class A-8 and Class A-9 Certificate Insurer or such time as a breach of any
representation and warranty materially and adversely affects the interests of
the Owners or of the Class A-8 and Class A-9 Certificate 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


                                       51
<PAGE>   65
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 Class A-8 and Class A-9 Certificate 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 in any material respect and has not been remedied shall constitute the
sole remedy available to the Owners, the Trustee and the Class A-8 and Class A-9
Certificate 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 Class A-8 and Class A-9 Certificate 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 Class A-8 and Class A-9
Certificate 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.

            SECTION 3.5. CONVEYANCE OF THE MORTGAGE LOANS. (a) The Sponsor,
concurrently with the execution and delivery hereof, and on behalf of the
Conduit Acquisition Trust, hereby 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 Class
A-8 and Class A-9 Certificate Insurer. The transfer by the Conduit Acquisition
Trust of the Mortgage Loans set forth on the Schedule of 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.


                                       52
<PAGE>   66
            (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 Closing
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 and
protect the Certificateholders' and the Class A-8 and Class A-9 Certificate
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 with respect to the Designated Advanta
      Mortgage Files 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 Class A-8 and Class A-9 Certificate
      Insurer and each Rating Agency has received an Opinion of Counsel,
      satisfactory in form and substance to the Class A-8 and Class A-9
      Certificate 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


                                       53
<PAGE>   67
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 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.


                                       54
<PAGE>   68

            (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, Standard & Poor's and Moody's, then any of
the Document Delivery Requirements described above may be waived by an
instrument signed by the Control Party, Standard & Poor's, and Moody's (or any
documents theretofore delivered to the Trustee returned to the Sponsor) on such
terms and subject to such conditions as the Control Party, Moody's and Standard
& Poor's 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 of the Notes delivered
by the Sponsor in the form attached as Exhibit D hereto, 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 Class A-8 and Class A-9
Certificate Insurer. The Trustee further agrees to review any other 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 Class A-8 and Class A-9 Certificate 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 Class A-8 and Class A-9 Certificate 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 Class A-8 and Class A-9 Certificate 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 Class A-8 and Class A-9
Certificate 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


                                       55
<PAGE>   69
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 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.

            (b) The Sponsor, the Master Servicer and the Trustee covenant to
provide each other and to the Class A-8 and Class A-9 Certificate 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.

            SECTION 4.1. ISSUANCE OF CERTIFICATES. On the Startup Day, upon the
Trustee's receipt from the Sponsor of an executed Delivery Order in the form set

the Sponsor the balance after deducting such amounts.


                                    ARTICLE V

                     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


                                       56
<PAGE>   70
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 Certificate 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
monies in 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 Class A-8 Certificates and the
Class A-9 Certificates upon the occurrence of certain events, from Group II
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, with
respect to the Class A-8 Certificates and the Class A-9 Certificates, (i) the
Group II 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.

            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.

            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.

            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


                                       57
<PAGE>   71
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 Class A-8 and
Class A-9 Certificate 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.

            (c) 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) 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) 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) 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 Class A-8 and


                                       58
<PAGE>   72
Class A-9 Certificate 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 Class A-8 and Class A-9 Certificate 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.

            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) the event that (i) the Depository or the Sponsor advises the
Trustee and the Class A-8 and Class A-9 Certificate Insurer in writing that the
Depository is no longer willing or able to discharge properly its
responsibilities as nominee and depository with respect to the 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 Class A-8 and
Class A-9 Certificate 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.

<PAGE>   73
            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 Standard & Poor's, or Moody's), 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 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


                                       60
<PAGE>   74
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.

            (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
described in section 4975(e)(1) of the Internal Revenue Code of 1986, 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. Any Class R
Certificate transferred shall (x) certify that it is not any of the above and
(y) deliver an opinion of counsel to that effect.

            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.

                                    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; 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 Class A-8
Certificates and the Class A-9 Certificates, from Group II 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 II 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 Class A-8
and Class A-9 Certificate Insurer on account of any Group II 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 Class
A-8 Certificates and the Class A-9 Certificates, the Class A-8 and Class A-9
Certificate Insurer for payment thereof (but only to the extent of the amounts
so paid to the Class A-8 and Class A-9 Certificate 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 Class A-8 and Class A-9 Certificate 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).

<PAGE>   76
            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 Class A-8 and
Class A-9 Certificate Insurer as their interests may appear, and, upon request
of the Class A-8 and Class A-9 Certificate Insurer, or with the Consent of the
Class A-8 and Class A-9 Certificate 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;

                  (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 Class
A-8 and Class A-9 Certificate 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 Class A-8 and
Class A-9 Certificate 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 Class A-8 and Class A-9
Certificate 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;

                  (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

            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

            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 Certificate Insurance Policy or for the appointment of a receiver or
trustee, or for any other remedy hereunder, unless:

                        (1) such Owner has previously given written notice to
            the Sponsor and the Trustee of such Owner's intention to institute
            such proceeding;

                        (2) 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;

                        (3) 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;

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

<PAGE>   78
                        (5) as long as any Class A-8 Certificates, Class A-9
            Certificates, or any Group II Reimbursement Amount are outstanding,
            the Class A-8 and Class A-9 Certificate Insurer consented in writing
            thereto; and

                        (6) no direction inconsistent with such written request
            has been given to the Trustee during such 60-day period by the Class
            A-8 and Class A-9 Certificate 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.

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 Class A-8 and Class A-9 Certificate Insurer, notwithstanding
any other provision of this Agreement.

            SECTION 6.8. UNCONDITIONAL RIGHTS OF OWNERS TO RECEIVE
DISTRIBUTIONS. Notwithstanding any other provision in this Agreement, the Owner
of any Certificate shall have the right, which is absolute and unconditional, to
receive distributions to the extent provided herein and therein with respect to
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
Trustee, the Class A-8 and Class A-9 Certificate Insurer or to the Owners is
intended to be exclusive of any 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 Class A-8 and Class A-9 Certificate 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 or remedy or constitute a waiver of any such Event
of Default or an acquiescence therein. Every right and remedy given by this
Article VI or by law to the Trustee, the Class A-8 and Class A-9 Certificate
Insurer or to the Owners may be exercised from time to time, and as often as may
be deemed expedient, by the Trustee, the Class A-8 and Class A-9 Certificate
Insurer or by the Owners, as the case may be.

            SECTION 6.11. CONTROL BY OWNERS. The Class A-8 and Class A-9
Certificate Insurer (so long as a Class A-8 and Class A-9 Insurer Default has
not occurred and is continuing)


                                       65
<PAGE>   79
or the Owners of a majority of the Percentage Interests represented by the
Offered Certificates 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 Outstanding, by such majority of the Percentage Interests
represented by the Class R Certificates then Outstanding, with the consent of
the Control Party (which may not be unreasonably withheld) may direct the time,
method and place of conducting any proceeding for any remedy available to the
Control Party with respect to the Certificates or exercising any trust or power
conferred on the 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 hereof; provided that:

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

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

                        (3) 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
            Class A-8 and Class A-9 Certificate Insurer conflict with each
            other, the Class A-8 and Class A-9 Certificate Insurer's direction
            shall prevail.

            So long as a Class A-8 and Class A-9 Certificate Insurer Default has
not occurred and is continuing, the Class A-8 and Class A-9 Certificate Insurer
shall act as the Control Party until all Group II Reimbursement Amounts have
been paid.

                                   ARTICLE VII

                      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

Estate and shall apply it as provided in this Agreement.

            SECTION 7.3. THE CERTIFICATE INSURANCE POLICY. (a) With respect to
the Group II Certificates only, on each Determination Date the Trustee shall
determine with respect to the immediately following Payment Date: the Group II
Monthly Remittance Amount on deposit in the Certificate Account on such Payment
Date (disregarding the amounts of any Group II Insured Payment) and equal to the
sum of (x) such amounts excluding the amount of any Group II 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(c)(i) for the
related Payment Date, plus (y) any amounts of Group II Monthly Excess Cashflow
to be applied on such Payment Date and any amounts available from Group I
Monthly Excess Cashflow pursuant to Section 7.5(f)(9); the amounts described in
the preceding clause (x) with respect to each Group II and Payment Date, after
taking into account the portion of the Group II Principal Distribution Amount to
be actually distributed on such Payment Date and without regard to any Group II
Insured Payment to be made with respect to such Payment Date, are the "Group II
Available Funds"; the sum of the amounts described in the preceding clauses (x)
and (y) are the "Group II Total Available Funds".

            (b) If the Group II Insured Distribution Amount for any, Payment
Date exceeds the Group II Total Available Funds for such Payment Date (after
taking into account the portion of the Group II Principal Distribution Amount to
be actually distributed on such Payment Date without regard to any Group II
Insured Payment to be made with respect to such Payment Date) (such amount being
a "Group II Deficiency Amount"), the Trustee shall complete a Notice in the form
of Exhibit A to the Certificate Insurance Policy and submit such notice to the
Class A-8 and Class A-9 Certificate 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 II Insured Payment in an amount equal to such Group II Deficiency Amount.
Upon receipt of Group II Insured Payments from the Class A-8 and Class A-9
Certificate Insurer under the Certificate Insurance Policy, the Trustee shall
deposit such Group II Insured Payments in the Certificate Account.

            (c) The Trustee shall distribute all Group II Insured Payments
received, or the proceeds thereof, in accordance with Section 7.5(c) to the
Owners of the Class A-8 Certificates and the Class A-9 Certificates.

            (d) The Trustee shall (i) receive Group II Insured Payments as
attorney-in-fact of each Owner of the Class A-8 Certificates and the Class A-9
Certificates of the related Class receiving any Group II Insured Payment from
the Class A-8 and Class A-9 Certificate Insurer and (ii) disburse such Group II
Insured Payment to the Owners of the Class A-8 Certificates and the Class A-9
Certificates as set forth in Section 7.5(c). The Class A-8 and Class A-9
Certificate Insurer shall be entitled to receive the related Group II
Reimbursement Amount pursuant to Sections 7.5(g)(2) and (4) hereof with respect
to each Group II Insured Payment made by the Class A-8 and Class A-9 Certificate
Insurer. The Trustee hereby agrees on behalf of each Owner of Class A-8
Certificates and Class A-9 Certificates and the Trust for the benefit of the
Certificate Insurer that it recognizes that to the extent the Class A-8 and
Class A-9 Certificate Insurer makes Group II Insured Payments, either directly
or indirectly (as by paying through the Trustee), to the Owners of such Class
A-8 Certificates and the Class A-9 Certificates, the Class A-8 and Class A-9
Certificate Insurer will be entitled to receive the Group II Reimbursement
Amount pursuant to Sections 7.5(g)(2) and (4) hereof.

            (e) The Trustee shall receive, as attorney-in-fact of each Owner of
a Class A-8 Certificate and Class A-9 Certificate, any Group II Insured Payment
from the Class A-8 and


                                       67
<PAGE>   81
Class A-9 Certificate Insurer and disburse the same to each Owner of a Class A-8
Certificate and Class A-9 Certificate in accordance with the provisions of
Section 7.3. Group II Insured Payments disbursed by the Trustee from proceeds of
the Certificate 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 Class A-8 Certificate and Class A-9 Certificate, and the Class
A-8 and Class A-9 Certificate Insurer shall become the owner of such unpaid
amounts due from the Trust Fund in respect of the Class A-8 Certificates and the
Class A-9 Certificates. The Trustee hereby agrees on behalf of each Owner of a
Class A-8 Certificate and Class A-9 Certificate for the benefit of the Class A-8
and Class A-9 Certificate Insurer that it recognizes that to the extent the
Class A-8 and Class A-9 Certificate Insurer makes any Group II Insured Payment,
either directly or indirectly (as by paying through the Trustee), to the Class
A-8 Certificateholders or the Class A-9 Certificateholder, the Class A-8 and
Class A-9 Certificate Insurer will be subrogated to the rights of the Class A-8
Certificateholder and the Class A-9 Certificateholder with respect to such Group
II Insured Payment, shall be deemed to the extent of payments so made to be a
registered Class A-8 Certificateholder and Class A-9 Certificateholder and shall
receive all future distributions until all such Group II Insured Payments by the
Class A-8 and Class A-9 Certificate Insurer, together with interest thereon at
the interest rate borne by the Class A-8 Certificates and Class A-9 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 Class A-8
and Class A-9 Certificate Insurer's rights as subrogee on the registration books
maintained by the Trustee or the Certificate Registrar upon receipt from the
Class A-8 and Class A-9 Certificate Insurer of proof of payment of any Group II
Insured Payment. The effect of the foregoing provisions is that, to the extent
of Group II Insured Payments made by it, the Class A-8 and Class A-9 Certificate
Insurer shall be paid before payment of the balance of the distributions are
made to the other Owners of the Class A-8 Certificates and Class A-9
Certificates.

      provided, that if the Group I Interest Amount Available is not sufficient

      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

after all preceding disbursements have occurred:

                  (i) On each Payment Date (a) before the Stepdown Date or (b)
      with respect to which a Group I Trigger Event is in effect, Owners of the

      Group I will be entitled to receive payment of 100% of the Group I
      Principal Distribution Amount as follows: (I) to the Owners of the Class

covenants and obligations of the Trust Parties under this section shall be
irrevocable and shall survive the termination of this Agreement.

            SECTION 7.9. ADDITIONAL REPORTS BY TRUSTEE. (a) The Trustee shall
report to the Sponsor, the Class A-8 and Class A-9 Certificate 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 Class A-8 and Class A-9 Certificate 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 Class A-8 and
Class A-9 Certificate Insurer, transmit promptly to the Sponsor, the Class A-8
and Class A-9 Certificate 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 Class A-8 and Class A-9
Certificate Insurer and the Master Servicer if any such receipts have not been
received by the Trustee.

            (b) The Trustee shall immediately report to the Class A-8 and Class
A-9 Certificate 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
1997-3" (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 the REMIC, and any amounts transferred from the 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 sum of the Class A-8 Current Interest and the
Class A-9 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 (i) to the Owners of the Class A-8
Certificates which are not receiving the Class A-8 Full Interest Distribution
Amount with respect to such Class on such Distribution Date the amount by which
such Class A-8 Full Interest Distribution Amount exceeds the Class A-8 Current
Interest on such Payment Date (the "Class A-8 Interest Shortfall") and (ii) to
the Owners of the Class A-9 Certificates which are not receiving the Class A-9
Full Interest Distribution Amount with respect to such Class on such
Distribution Date the amount by which such Class A-9 Full Interest Distribution
Amount exceeds the Class A-9 Current Interest


                                       80
<PAGE>   94
on such Payment Date (the "Class A-9 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 (x) to the Class A-8 Certificates, an amount equal
to the product of (a) a fraction, the numerator of which is the Class A-8
Interest Shortfall and the denominator of which is the Formula Interest
Shortfall and (b) the Supplemental Interest Payment Amount Available and (y) to
the Class A-9 Certificates, an amount equal to the product of (a) a fraction,
the numerator of which is the Class A-9 Interest Shortfall and the denominator
of which is the Formula Interest Shortfall and (b) the Supplemental Interest
Payment Amount Available.

            (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.


                                  ARTICLE VIII

                          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 Class A-8
and Class A-9 Certificate 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 Class A-8 and
Class A-9 Certificate 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 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.

<PAGE>   95
            (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 Class A-8
and Class A-9 Certificate 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 Class A-8 and Class A-9 Certificate Insurer and
(y) will not cause the REMIC Trust 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 the REMIC Trust shall constitute, and
that the affairs of REMIC Trust shall be conducted so as to qualify it 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 the REMIC Trust and that in such capacity it
shall: (i) use its best efforts to conduct the affairs of the REMIC Trust at all
times that any Class of Certificates are outstanding so as to maintain the
status of the REMIC Trust 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 REMIC Trust or that would subject
the Trust to tax and (iii) exercise reasonable care not to allow the REMIC Trust
to receive income from the performance of services or from assets not permitted
under the REMIC Provisions to be held by a 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 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 Class A-8 and Class A-9 Certificate Insurer and


                                       82
<PAGE>   96
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 Section
7.5(h)(1) hereof.

            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 Class A-8 and Class A-9 Certificate Insurer and the Trustee of the
appointment of any Sub-Servicer and shall furnish to the Class A-8 and Class A-9
Certificate 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


                                       83
<PAGE>   97
Loans when any Sub-Servicer has received such payments. 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 Class A-8
and Class A-9 Certificate 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 Class A-8 and
Class A-9 Certificate Insurer, as their interests may appear, and maintain at
one or more Designated Depository Institutions the Principal and Interest
Account.


                                       84
<PAGE>   98
            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 Class A-8 and Class A-9 Certificate 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 Loan Balance of the related Mortgage Loan.

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

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

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

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

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


                                       85
<PAGE>   99
                  (E) to clear and terminate the Principal and Interest Account
      following the termination of the Trust Estate pursuant to Article X.

                  (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 Class A-8 and Class A-9 Certificate 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 Class A-8 and Class A-9 Certificate
Insurer, the Trustee, Moody's and Standard & Poor's, then the requirement to
maintain the Principal and Interest Account may be waived by an instrument
signed by the Class A-8 and Class A-9 Certificate Insurer, Standard & Poor's,
Trustee, and Moody's, 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 Class A-8 and Class A-9 Certificate Insurer, the Trustee, Moody's and
Standard & Poor's 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 Section 7.5(h)(1) 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


                                       86
<PAGE>   100
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 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 Section 7.5(h)(1) 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 Section 7.5(h)(1) hereof.

            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 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


                                       87
<PAGE>   101
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 Class A-8 and Class A-9 Certificate Insurer
out of the Master Servicer's own funds for any loss to the Trust and the Class
A-8 and Class A-9 Certificate 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 Class A-8 and Class A-9 Certificate
Insurer, the Master Servicer shall cause to be delivered to the Trustee and the
Class A-8 and Class A-9 Certificate 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 Class A-8 and Class A-9 Certificate 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 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


                                       88
<PAGE>   102
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 23 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 Class A-8 and Class A-9
Certificate 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 Class A-8
and Class A-9 Certificate 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) 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


                                       89
<PAGE>   103
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 Class A-8 and Class
A-9 Certificate 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
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


                                       90
<PAGE>   104
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 Class A-8 and Class A-9 Certificate Insurer, Moody's and Standard & Poor's
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) above, or approved, with respect to clause (iii) above, by an Authorized
Officer of the Master


                                       91
<PAGE>   105
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 Class A-8 and
Class A-9 Certificate Insurer, Standard & Poor's, and Moody's, 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 Class A-8 and Class A-9 Certificate Insurer, Standard & Poor's and
Moody's 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 Class A-8 and Class A-9 Certificate Insurer, the FDIC and the supervisory
agents and examiners of each of the foregoing access to the documentation
regarding the Mortgage Loans required by


                                       92
<PAGE>   106
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.

            Upon any change in the format of the computer tape maintained by the
Master Servicer in respect of the Mortgage Loans, the Master Servicer shall
deliver a copy of such computer tape to the Trustee and in addition shall
provide a copy of such computer tape to the Trustee at such other times as the
Trustee may reasonably request. The Class A-8 and Class A-9 Certificate Insurer
may request a copy of this computer tape upon 3 Business Days prior written
notice to the Master Servicer.

            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 Class A-8
and Class A-9 Certificate 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 Class A-8 and Class A-9 Certificate Insurer and Moody's.

            SECTION 8.20. REMOVAL OF MASTER SERVICER; RESIGNATION OF MASTER
SERVICER. (a) The Trustee, with the consent of the Class A-8 and Class A-9
Certificate 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 proceeds or required payment, which failure continues unremedied for
      five Business Days following written notice to an Authorized Officer of
      the Master Servicer from the Trustee or from any Owner.

                  (ii) The Master Servicer shall (I) apply for or consent to the

      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 the Master Servicer or of all or any substantial part of its assets, or
      other like relief in respect thereof under any bankruptcy or insolvency
      law, and, if such proceeding is being contested by the Master Servicer in


                                       93
<PAGE>   107
      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 Class A-8 and
      Class A-9 Certificate 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

                  (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 Class
      A-8 and Class A-9 Certificate 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 II Total Available Funds Shortfall; provided,
      however, that the Class A-8 and Class A-9 Certificate 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 Class A-8
      and Class A-9 Certificate 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 Class A-8
      and Class A-9 Certificate Insurer and the Trustee; or

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

                  (v) (a) if on any Payment Date of the first sixty Payment
      Dates after the Startup Day the aggregate Total Expected Losses for all
      prior Remittance Periods since the Startup Day exceed 7.0% of the Original
      Pool Balance and (b) if on any Payment Date thereafter the Total Expected
      Losses for all prior Remittance Periods since the Startup Day exceed 9.0%
      of the Original Pool Balance;

provided, however, with respect to clauses (iv), (v), (vi) and (vii), if the
Master Servicer can demonstrate to the reasonable satisfaction of the Control
Party that any such event was due to


                                       94
<PAGE>   108
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 (y) in the event of the refusal or
inability of the Master Servicer to make any required Delinquency 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 Class A-8
and Class A-9 Certificate Insurer or of the Trustee) at 4 p.m. on the second
Business Day following the day on which the Trustee or the Class A-8 and Class
A-9 Certificate Insurer notifies an Authorized Officer of the Master Servicer
that a required Delinquency Advance has not been received by the Trustee. Upon
the Trustee's determination that a required Delinquency 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
Class A-8 and Class A-9 Certificate 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 Class A-8 and Class A-9 Certificate 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 Class A-8
and Class A-9 Certificate 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 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


                                       96
<PAGE>   110
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 Moody's and Standard and & Poor's of the
transfer of the servicing to the successor.

            (l) The Trustee shall give notice to the Class A-8 and Class A-9
Certificate Insurer, Moody's, Standard & Poor's and to the Owners of the
occurrence of any event specified in Section 8.20(a) of which the Trustee has
knowledge.

            (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 CLASS A-8 AND CLASS A-9 CERTIFICATE
INSURER AND THE TRUSTEE; ERRORS AND OMISSIONS INSURANCE. (a) At any reasonable
time and from time to time upon reasonable notice, the Class A-8 and Class A-9
Certificate 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).

<PAGE>   111
            SECTION 8.23. NOTICES OF MATERIAL EVENTS. The Master Servicer shall
give prompt notice to the Class A-8 and Class A-9 Certificate Insurer, the
Trustee, Moody's and Standard & Poor's of the occurrence of any of the following
events:

            (a) Any default or any fact or event which results, or which with
notice or the passage of time, or both, would result in the occurrence of a
default by the Sponsor, any Originator or the Master Servicer under any
Transaction Document or would constitute a material breach of a representation,
warranty or covenant under any Transaction Document;

            (b) 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;

            (c) 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

            (d) 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
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 Certificate 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


                                       98
<PAGE>   112
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 (a) 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 (b) any unreimbursed Delinquency
Advances, Servicing Advances and Nonrecoverable Advances 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 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 if termination would result in a draw on the
Certificate 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 REMIC Trust.

            (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.

            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


                                       99
<PAGE>   113
any appeal is taken, following a final determination of such appeal from which
no further appeal can be taken, to the effect that the REMIC Trust does 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 the REMIC Trust 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 Class A-8 and Class A-9 Certificate
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 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 the REMIC Trust 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


                                      100
<PAGE>   114
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.

                                   THE TRUSTEE

            SECTION 10.1. CERTAIN DUTIES AND RESPONSIBILITIES. (a) The Trustee
(i) undertakes to perform such duties and only such duties as are specifically
set forth in this Agreement, and no implied covenants or obligations shall be
read into this Agreement against the Trustee and (ii) in the absence of bad
faith on its part, may conclusively rely, as to the truth of the statements and
the correctness of the opinions expressed therein, upon certificates or opinions
furnished pursuant to and conforming to the requirements of this Agreement; but
in the case of any such certificates or opinions which by any provision hereof
are specifically required to be furnished to the Trustee, shall be under a duty
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 hereunder whether following the failure of the Master Servicer to
perform, pursuant to Section 8.20 hereof or otherwise. Specifically, and not in
limitation of the foregoing, the Trustee shall have the power:

                  (i) to collect Mortgagor payments;

                  (ii) to foreclose on defaulted Mortgage Loans;

                  (iii) to enforce due-on-sale clauses and to enter into
      assumption and substitution agreements as permitted by Section 8.12
      hereof;

                  (iv) to deliver instruments of satisfaction pursuant to
      Section 8.14;

                  (v) to make Delinquency Advances and Servicing Advances and to
      pay Compensating Interest, and

                  (vi) to enforce the Mortgage Loans.

<PAGE>   115
            (c) No provision of this Agreement shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act or its own willful misconduct, except that:

                  (i) his subsection shall not be construed to limit the effect
      of subsection (a) of this Section;

                  (ii) the Trustee shall not be liable for any error of judgment
      made in good faith by an Authorized Officer, unless it shall be proved
      that the 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 Class A-8 and Class A-9 Certificate Insurer or of the
      Owners of a majority in Percentage Interest of the Certificates of the
      affected Class or Classes and the Class A-8 and Class A-9 Certificate
      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.

            (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 the occurrence of any of the
following events (whatever the reason for such event and whether it shall be
voluntary or involuntary or be effected by operation of law or pursuant to any
judgment, decree or order of any court or any order, rule or regulation of any
administrative or governmental body):

            breach, any covenant or agreement of the Trustee in this Agreement,
            or if any representation or warranty of the Trustee made in this
            Agreement or in any certificate or other writing delivered pursuant
            hereto or in connection herewith shall prove to be incorrect in any
            material respect as of the time when the same shall have been made,
            and such failure or breach shall continue or not be cured for a
            period of 30 days after there shall have been given, by registered

            appointed in any insolvency, readjustment of debt, marshalling of
            assets and liabilities or similar proceedings of or relating to the
            Trustee or relating to all or substantially all of its property; or

                        (5) the Trustee shall become insolvent (however
            insolvency is evidenced), generally fail to pay its debts as they
            come due, file or consent to the filing of a petition to take

<PAGE>   117
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

paper or document believed by it to be genuine and to have been signed or
presented by the proper party or parties;

            (b) any request or direction of the Sponsor, the Class A-8 and Class
A-9 Certificate Insurer or the Owners of any Class of Certificates mentioned
herein shall be sufficiently evidenced in writing;

            (c) whenever in the administration of this Agreement the Trustee
shall deem it desirable that a matter be proved or established prior to taking,
suffering or omitting any action hereunder, the Trustee (unless other evidence
be herein specifically prescribed) may, in the absence of bad faith on its part,
rely upon an Officer's Certificate;

            (d) the Trustee may consult with counsel, and the written advice of
such counsel shall be full and complete authorization and protection in respect
of any action taken, suffered or omitted by it hereunder in good faith and in
reasonable reliance thereon;

            (e) the Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Agreement at the request or direction of
any of the Owners pursuant to this Agreement, unless such Owners shall have
offered to the Trustee reasonable security or indemnity against the costs,
expenses and liabilities which might be incurred by it in compliance with such
request or direction;

            (f) the Trustee shall not be bound to make any investigation into
the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond,
note or other paper or document, but the Trustee in its discretion may make such
further inquiry or investigation into such facts or matters as it may see fit;

            (g) the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed and supervised with
due care by it hereunder; and

            (h) the Trustee shall not be liable for any action it takes or omits

Agreement other than as to validity and sufficiency of its authentication of the
Certificates.

            SECTION 10.4. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF
CERTIFICATES. The recitals contained herein and in the Certificates, except any
such recitals relating to the Trustee, shall be taken as the statements of the
Sponsor and the Trustee assumes no responsibility for


                                      104
<PAGE>   118
their correctness. The Trustee makes no representation as to the validity or
sufficiency of this Agreement or of the Certificates other than as to validity
and sufficiency of its authentication of the Certificates.

            SECTION 10.5. MAY HOLD CERTIFICATES. The Trustee or any agent of the
Trust, in its individual or any other capacity, may become an Owner or pledgee
of Certificates and may otherwise deal with the Trust with the same rights it
would have if it were not Trustee or such agent.

            SECTION 10.6. MONEY HELD IN TRUST. Money held by the Trustee in
trust hereunder need not be segregated from other trust funds except to the
extent required herein or required by law. The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise
agreed with the Sponsor and except to the extent of income or other gain on
investments which are deposits in or certificates of deposit of the Trustee in
its commercial capacity and income or other gain actually received by the
Trustee on Eligible Investments.

            SECTION 10.7. NO LIEN FOR FEES. The Trustee shall have no lien on
the Trust Estate for the payment of any fees and expenses.

            SECTION 10.8. CORPORATE TRUSTEE REQUIRED; ELIGIBILITY. There shall
at all times be a Trustee hereunder which shall be a corporation or association
organized and doing business under the laws of the United States of America or
of any State authorized under such laws to exercise corporate trust powers,
having a combined capital and surplus of at least $100,000,000, subject to
supervision or examination by the United States of America or any such State
having a rating or ratings acceptable to the Class A-8 and Class A-9 Certificate
Insurer or, if the last sentence of Section 11.18 hereof is applicable, the
Sponsor and having (x) long-term, unsecured debt rated at least A-1 by Moody's
(or such lower rating as may be acceptable to Moody's) and (y) a short-term
deposit rating of at least A-1 from Standard & Poor's (or such lower rating as
may be acceptable to Standard & Poor's). If such Trustee publishes reports of
condition at least annually, pursuant to law or to the requirements of the
aforesaid supervising or examining authority, then for the purposes of this
Section, the combined capital and surplus of such corporation or association
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition 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 the Sponsor (with the consent of the Class A-8 and Class A-9
Certificate Insurer) (which consent shall not be unreasonably withheld) or of
the Class A-8 and Class A-9 Certificate Insurer, resign immediately in the
manner and with the effect hereinafter specified in this Article X.

            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 acceptance
of appointment by the successor trustee under Section 10.10 hereof.

            (b) The Trustee, or any trustee or trustees hereafter appointed, may
resign at any time by giving written notice of resignation to the Sponsor and by
mailing notice of resignation by first-class Mail, postage prepaid, to the Class
A-8 and Class A-9 Certificate Insurer and the Owners at their addresses
appearing on the Register. A copy of such notice shall be sent by the resigning
Trustee to Moody's and Standard & Poor's. Upon receiving notice of resignation,
the

                                      105
<PAGE>   119
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 Class A-8 and Class A-9 Certificate Insurer, the Class A-8
and Class A-9 Certificate Insurer or the Sponsor (with the written consent of
the Class A-8 and Class A-9 Certificate 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 Class A-8 and Class A-9 Certificate 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 Class A-8 and Class A-9
Certificate 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 Class
A-8 and Class A-9 Certificate 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 Class A-8 and Class
A-9 Certificate Insurer and the Sponsor duly authorized, one complete set of
which instruments shall be delivered to the Sponsor, one complete set to the
Class A-8 and Class A-9 Certificate 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 Class
A-8 and Class A-9 Certificate 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
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.


                                      106
<PAGE>   120
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 Class
A-8 and Class A-9 Certificate 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 Moody's, Standard & Poor's and the
Class A-8 and Class A-9 Certificate 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.


                                      107
<PAGE>   121
            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 Class A-8 and Class A-9 Certificate 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 Class A-8 and Class A-9 Certificate 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.


                                      108
<PAGE>   122
            Every separate Trustee and co-Trustee shall, to the extent
permitted, be appointed and act subject to the following provisions and
conditions:

                  (i) All rights, powers, duties and obligations conferred or
      imposed upon the Trustee shall be conferred or imposed upon and exercised
      or performed by the Trustee and such separate Trustee or co-Trustee
      jointly (it being understood that such separate Trustee or co-Trustee is
      not authorized to act separately without the Trustee joining in such act),
      except to the extent that under any law of any jurisdiction in which any
      particular act or acts are to be performed (whether as Trustee hereunder
      or as successor to the Master Servicer hereunder), the Trustee shall be
      incompetent or unqualified to perform such act or acts, in which event
      such rights, powers, duties and obligations (including the holding of
      title to the Trust 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 Class A-8 and
Class A-9 Certificate 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 Class A-8 and Class A-9 Certificate
Insurer or the Owners to the


                                      109
<PAGE>   123
Trustee to take any action under any provision of this Agreement, the Sponsor,
the Class A-8 and Class A-9 Certificate 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 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.

<PAGE>   124
            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 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 Class A-8 and Class A-9
Certificate 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 Class A-8 and Class
A-9 Certificate 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


                                      111
<PAGE>   125
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.

            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 Class A-8 and Class A-9 Certificate 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


                                      112
<PAGE>   126
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.

                  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. The Trustee, the Sponsor and the
Master Servicer, may at any time and from time to time, with the prior written
consent of the Class A-8 and Class A-9 Certificate 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 Class A-8
and Class A-9 Certificate 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 

                                      113
<PAGE>   127
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 Class A-8 and Class A-9 Certificate 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 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 Class A-8 and Class A-9 Certificate
Insurer to the effect that such amendment would not adversely affect the status
of the REMIC Trust 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 Class A-8 and Class A-9 Certificate Insurer, the
Owners, Moody's and Standard & Poor's 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. 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 REMIC Trust 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 the
REMIC Trust as a REMIC (which election shall apply to the taxable period ending
December 31, 1996 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, 

                                      114
<PAGE>   128
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.

                  (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 REMIC Trust, (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 REMIC Trust of any other taxes under the Code.

                  (f) The REMIC Trust 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 Class A-8 and Class A-9 Certificate 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 the REMIC Trust; provided, however, that such transaction is
otherwise permitted under this Agreement.

                  SECTION 11.16. ADDITIONAL LIMITATION ON ACTION AND IMPOSITION
OF TAX. Any provision of this Agreement to the contrary notwithstanding, the
Trustee shall not, without having obtained, and delivered to the Class A-8 and
Class A-9 Certificate 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 the REMIC Trust, (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.

                                      115
<PAGE>   129
                  (b) In the event that any tax is imposed on "prohibited
transactions" of the REMIC Trust 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 the REMIC Trust 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 otherwise (iii) the Owners of the Class R Certificates in
proportion to their Percentage Interests. To the extent such tax is chargeable
against the Owners of 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 CLASS A-8 AND CLASS A-9 CERTIFICATE
INSURER. The Class A-8 and Class A-9 Certificate Insurer is a third-party
beneficiary of this Agreement. Any right conferred to the Class A-8 and Class
A-9 Certificate Insurer shall be suspended during any period in which the Class
A-8 and Class A-9 Certificate Insurer is in default in its payment obligations
under the Certificate Insurance Policy, except with respect to amendments to
this Agreement pursuant to Section 11.14. During the continuance of a Class A-8
and Class A-9 Certificate Insurer Default, the Class A-8 and Class A-9
Certificate 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
Certificate Insurance Policy has expired or a Class A-8 and Class A-9
Certificate 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 Class A-8 and Class A-9 Certificate Insurer under the
Insurance Agreement have been paid in full, and the Certificate Insurance Policy
has expired or is unavailable due to a Class A-8 and Class A-9 Certificate
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 Class A-8 and Class A-9 Certificate Insurer has been
reimbursed for all Group II Reimbursement Amounts to which it is entitled
hereunder and the Certificate Insurance Policy has expired, the Class A-8 and
Class A-9 Certificate Insurer's rights hereunder shall terminate.

                  SECTION 11.19. MAINTENANCE OF RECORDS. Each Originator and
Owner of a Class R Certificate shall each continuously keep an original executed
counterpart of this Agreement in its official records.

         any material contract, agreement or other instrument to which such
         Affiliated Originator or its properties is a party or by which such
         Affiliated Originator is bound or violate any statute or any order,

         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.

         Affiliated Originator will not be rendered insolvent as a result of the
         sale of the Mortgage Loans to the related Advanta Trust.

         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.

                  Section 5. Representations and Warranties of the Affiliated
Originators 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
Conveyance Agreement may, with respect to the Mortgage Loans in the related
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,
together with any Additional Representations and Warranties, are the
"Representations and Warranties". Reference to the Cut-Off Date are as of the
Cut-Off Date set forth in the related Conveyance Agreement with respect to a
Mortgage Loan.

                  (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 to be delivered to the Trustee pursuant to the related Advanta
         Pooling Agreement (including all material documents related thereto)
         with respect to each Mortgage Loan has been or will be delivered to the
         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
         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

         mortgages, 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;

                                       10
<PAGE>   14
                         (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;

                      (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

                                       11
<PAGE>   15
         (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;

                      (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

                                       12
<PAGE>   16
         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;

                      (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

                                       13
<PAGE>   17
         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
         related Mortgagor;

                      (xxxi) With respect to each Second Mortgage Loan and each
         Third Mortgage Loan, either (A) no consent for such Mortgage Loan was
         required by the holder of the related Senior Lien (and, in the case of
         a Third Mortgage Loan, the holder of the related second lien) prior to
         the

                                       14
<PAGE>   18
         making of such Mortgage Loan or (B) such consent has been obtained and
         is contained in the related File;

                     (xxxii) Each Mortgage contains customary and enforceable
         provisions which render the rights and remedies of the holder thereof
         adequate for the realization against the related Property of the
         benefits of the security, including (A) in the case of a Mortgage
         designated as a deed of trust, by trustee's sale and (B) otherwise by
         judicial foreclosure. There is no homestead or other exemption
         available which materially interferes with the right to sell the
         related Property at a trustee's sale or the right to foreclose the
         related Mortgage;

                    (xxxiii) Except as provided by clause (viii) of this
         Section, there is no default, breach, violation or event of
         acceleration 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;

                     (xxxiv) Except for any Bulk Acquisition Loan, no instrument
         of release or waiver has been executed in connection with any Mortgage
         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

                                       15
<PAGE>   19
                     (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
such Representation or Warranty concerning the knowledge of the Affiliated
Originator as to the facts stated therein, which breach, in the opinion of the
Sponsor, materially and adversely affects the interests of the Sponsor, the
Owners or of the Certificate Insurer in the related Mortgage Loan or Mortgage
Loans, the party discovering such breach shall give prompt written notice to the
other party, and the related Affiliated Originator shall be required to take the
remedial actions required by the related Advanta Pooling Agreement within the
time periods required thereto. Each Affiliated Originator hereby acknowledges
that a breach of any of the Representations and Warranties listed in clauses
(iii), (x), (xvi) and (xxxviii) above a priori materially and adversely affects
the interests of the related Advanta Trust, the related Owners and the
Certificate Insurer.

                  Section 6. Authorized Representatives. The names of the

given, but the Trustee shall be entitled to rely conclusively on the last
exhibit until receipt of a superseding exhibit.

relating to this Agreement shall be in writing and shall be deemed to have been
duly given when received by the other party or parties at the address shown

              Class A-8 Group II Certificates and $365,000,000

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

         Notwithstanding the foregoing paragraph, this Policy does not cover
shortfalls, if any, attributable to the liability of the Trust or the Trustee
for withholding taxes, if any (including interest and penalties in respect of
any such liability). This Policy does not cover, and Insured Payments do not
include, Civil Relief Act Shortfalls.

         The Certificate Insurer will pay any Insured Payment that is a
Preference Amount on the Business Day following receipt on a Business Day by the
Fiscal Agent (as described below) of (i) a certified copy of the order requiring
the return of such a preference payment, (ii) an opinion of counsel satisfactory
to the Certificate Insurer that such order is final and not subject to appeal,
(iii) an assignment in such form as is reasonably required by the Certificate
Insurer, irrevocably assigning to the Certificate Insurer all rights and claims
of the Owner relating to or arising under the Obligations against the debtor
which made such preference payment or otherwise with respect to such preference
payment and (iv) appropriate instruments to effect the appointment of the
Certificate Insurer as agent for such Owner in any legal proceeding related to
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
<PAGE>   3
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
receipt in New York, New York on a Business Day by State Street Bank and Trust
Company, N.A., as Fiscal Agent for the Certificate Insurer or any successor
fiscal agent appointed by the Certificate Insurer (the "Fiscal Agent") of a
Notice (as described below); provided that if such Notice is received after
12:00 noon New York City time on such Business Day, it will be deemed to be
received on the following Business Day. If any such Notice received by the
Fiscal Agent is not in proper form or is otherwise insufficient for the purpose
of making claim hereunder it shall be deemed not to have been received by the
Fiscal Agent for purposes of this paragraph, and the 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.

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

         The Fiscal Agent is the agent of the Certificate Insurer only and the

                    Services, Inc. ("Advanta") and Lehman Brothers Inc. (as
                    Representative of the Underwriters, the "Representative")
                    ----------------------------------------------------------
Ladies and Gentlemen:

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

                Now, therefore, the Underwriter, the Certificate Insurer and
AMHC do hereby agree that:

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

                (ii)    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 Representative by Advanta or another
                        affiliate of AMHC.

<PAGE>   6
                  (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

         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 six months ended June
         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 June
         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.

                  (f) Certificate Insurer Information. The information in the
         Prospectus Supplement as of the date hereof under the captions "THE
         CLASS A-8 AND CLASS A-9 INSURER" and "THE CLASS A-8 AND CLASS A-9
         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 Policies.

                  (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

                                       3

         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
8H 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 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 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 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 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.

                                       4
<PAGE>   8
                  (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 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 Class A-8 and Class A-9 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 Class A-8 and Class A-9 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 Class A-8 and Class A-9 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 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 

                                       5
<PAGE>   9
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 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.

                                       6
<PAGE>   10
         (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 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

                                       7
<PAGE>   11
Underwriter Party, any Sponsor Party or any Insurer Party, (ii) the issuance of
any Class A-8 and Class A-9 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
