                  qualification, and has all power and authority necessary to
                  own or hold its properties, to conduct the business in which

                  Purchase Agreement or this Agreement, as the case may be, or
                  (d) which might materially and adversely affect the

                  Agreement, the Indemnification Agreement, the Purchase

                  shall be necessary during such same period to amend or
                  supplement the Prospectus or to file under the Exchange Act

                  confirmation of the effectiveness of the Registration
                  Statement. No stop order suspending the effectiveness of the

                  issued and no proceeding for that purpose shall have been

<PAGE>   12
                           B. None of the Underwriters shall have discovered and
                  disclosed to the Company on or prior to the Closing Date that

                  or supplement thereto contains an untrue statement of a fact
                  or omits to state a fact which, in the opinion of Dewey
                  Ballantine LLP, 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

                  transactions contemplated hereby shall be satisfactory in all
                  respects to counsel for the Underwriters, and the Company
                  shall have furnished to such counsel all documents and
                  information that they may reasonably request to enable them to

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

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



                                       12
<PAGE>   13
                  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.

                           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



                                       13
<PAGE>   14
                  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 to the
                  Pooling and Servicing Agreement comply with the terms thereof,
                  the Trust will be treated as a REMIC, the 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



                                       14

                  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 statements 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



                                       15

                  this Agreement and that, to the best of his or her knowledge
                  based upon reasonable investigation:

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

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

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

                           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 March 31, 1998, and no such amendment has been
                  authorized. No event has occurred since March 31, 1998, 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 March 31, 1998;

                           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

<PAGE>   17
                  direction of which has not been indicated, in the rating, if
                  any, accorded the Company or in any rating accorded any
                  securities of the Company, if any, by any "nationally
                  recognized statistical rating organization," as such term is
                  defined for purposes of the 1933 Act; and

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

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

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

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

                                       17
<PAGE>   18
                           4. the Certificates have been duly executed,
                  authenticated and delivered by the Trustee; and

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

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

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

                           J. The Policy relating to the Certificates shall have
                  been duly executed and issued at or prior to the Closing Date
                  and shall conform in all material respects to the description
                  thereof in the Prospectus. K. The Representative shall have
                  received a favorable opinion of in-house counsel to the
                  Insurer, dated the Closing Date and in form and substance
                  satisfactory to counsel for the Underwriters, to the effect
                  that:

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

                           2. The execution and delivery by the Insurer of the
                  Policy, and the Indemnification Agreement are within the
                  corporate power of the Insurer and have been authorized by all
                  necessary corporate action on the part of the Insurer; the
                  Policy has been duly executed and is the valid and binding



                                       18
<PAGE>   19
                  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 constitutes the legal, valid and
                  binding obligations of the Insurer enforceable in accordance
                  with its terms except that the enforcement of the
                  Indemnification Agreement may be limited by laws relating to
                  bankruptcy, insolvency, reorganization, moratorium,
                  receivership and other similar laws affecting creditors'
                  rights generally and by general principles of equity and by
                  public policy considerations relating to indemnification for
                  securities law violations.

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

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

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

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

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



                                       19
<PAGE>   20
                           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 Securities Act.

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

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

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

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

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

                           4. The tables regarding the Insurer's capitalization
                  set forth under the heading "THE CERTIFICATE INSURANCE POLICY"
                  and "THE



                                       20
<PAGE>   21
                  CERTIFICATE INSURER" presents fairly the capitalization of the
                  Insurer as of March 31, 1998;

                           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
                  Securities Act;

                           6. The audited balance sheet of the Insurer as of
                  December 31, 1997 and the related statement of income and
                  retained earnings for the fiscal year then ended, and the
                  accompanying footnotes, together with the related opinion of
                  an independent certificated public accountant, copies of which
                  are incorporated by reference in the Prospectus Supplement,
                  fairly present in all material respects the financial
                  condition of the Insurer as of such date and for the period
                  covered by such statements in accordance with generally
                  accepted accounting principles consistently applied; the
                  unaudited balance sheet of the Insurer as of March 31, 1998
                  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, 1997 audited statements.

                           7. to the best knowledge of such officer, since March
                  31, 1998, 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 LLP, special counsel to the Company, a survey in
                  form and substance satisfactory to the Representative,

                  Company shall have complied with all such requirements.

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

                           R. The Representative and counsel for the
                  Underwriters shall have received copies of any opinions of
                  counsel to the Company supplied to the Trustee relating to

                  shall be dated the Closing Date and addressed to the
                  Underwriters or accompanied by reliance letters to the
                  Underwriters or shall state the Underwriters may rely thereon.

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

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

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

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

<PAGE>   23
                  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 VIII. Payment of Expenses. The Company agrees to pay:

                  Section IX. 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 (as
                  defined herein)) furnished to the Company through the
                  Representative specifically for inclusion therein; and
                  provided, further, that as to any Preliminary Prospectus this
                  indemnity shall not inure to the benefit of any Underwriter or
                  any controlling person on account of any loss, claim, damage,
                  liability or action arising from the sale of the Offered
                  Certificates to any person by such Underwriter if such
                  Underwriter failed to send or give a copy of the Prospectus,
                  as amended or supplemented, to that person within the time
                  required by the Securities Act, and the untrue statement or
                  alleged untrue statement of a material fact or the omission or
                  alleged omission to state a material fact in the Preliminary
                  Prospectus was corrected in the Prospectus, unless such
                  failure resulted from non-compliance by the Company with
                  Section V(C). For purposes of the

                                       24
<PAGE>   25
                  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 (including any Derived Information (as defined
                  herein)) 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



                                       25

                  VIII except to the extent it has been materially prejudiced by
                  such failure, and provided, further, that the failure to
                  notify any indemnifying party shall not relieve it from any
                  liability which it may have to any indemnified party otherwise
                  than under this Section VIII.

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

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



                                       26
<PAGE>   27
                  Notwithstanding the foregoing sentence, if at any time an
indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel, the indemnifying party
agrees that it shall be liable for any settlement of any proceeding effected
without its written consent if (i) such settlement is entered into more than 30
days after receipt by such indemnifying party of the aforesaid request and (ii)
such indemnifying party shall not have reimbursed the indemnified party in
accordance with such request prior to the date of such settlement.

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

                           E. Each Underwriter agrees, assuming all
                  Company-Provided Information (defined below) is accurate and
                  complete in all material respects, to severally and not
                  jointly indemnify and hold harmless the Company, each of the
                  Company's officers and directors and each person who controls
                  the Company within the meaning of Section 15 of the Securities
                  Act against any and all losses, claims, damages or
                  liabilities, joint or several, to which they may become
                  subject under the Securities Act or otherwise, insofar as such
                  losses, claims, damages or liabilities (or actions in respect
                  thereof) arise out of or are based upon any untrue statement
                  of a material fact contained in the Derived Information
                  provided by such Underwriter, or arise out of or are based
                  upon the omission or alleged omission to state therein a
                  material fact required to be stated therein or necessary to
                  make the statements therein, in the light of the circumstances
                  under which they were made, not misleading, and agrees to
                  reimburse each such indemnified party for any legal or other
                  expenses reasonably incurred by him, her or it in connection
                  with investigating or defending or preparing to defend any
                  such loss, claim, damage, liability or action as such expenses
                  are incurred. The obligations of each of the Underwriters
                  under this Section VIII(E) shall be in addition to any
                  liability which such Underwriter may otherwise have.

                  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

                                       27
<PAGE>   28
                  (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.

                  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



                                       28
<PAGE>   29
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 Offered 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 X. 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 XI. 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 XII. 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 Morgan Stanley &
                  Co. Incorporated, as

                  Representative of the Underwriters, 1585 Broadway, New York,

                  212-761-0782);

                           B. if to the Company, shall be delivered or sent by
                  mail, telex or facsimile transmission to Advanta Mortgage
                  Conduit Services, Inc. 16875 West Bernardo Drive, San Diego,
                  California 92127 Attention: General Counsel (Fax:
                  619-674-3592).

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

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 Insurer. Upon the
discovery by the Sponsor, the Master Servicer, the 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 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



                                       66
<PAGE>   71

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 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 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 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
Insurer or such time as a breach of any representation and warranty materially
and adversely affects the interests of the Owners or of the Insurer as set forth
above, the Sponsor hereby covenants and warrants that it shall promptly cure
such breach in all material respects or it shall (or shall cause an affiliate of
the Sponsor to or an Originator to), subject to the further requirements of this
paragraph, on the second Remittance Date next succeeding such discovery, receipt
of notice or such other time (i) substitute in lieu of each Mortgage Loan in the
related Mortgage Loan Group which has given rise to the requirement for action
by the Sponsor a Qualified Replacement Mortgage and deliver the Substitution
Amount applicable thereto, together with the aggregate amount of all Delinquency
Advances and Servicing Advances theretofore made with respect to such Mortgage
Loan, to the Master Servicer for deposit in the Principal and Interest Account
or (ii) purchase such Mortgage Loan from the REMIC Trust at a purchase price
equal to the Loan Purchase Price thereof, which purchase price shall be
delivered to the Master Servicer for deposit in the Principal and Interest
Account. In connection with any such proposed purchase or substitution, the
Sponsor at its expense, shall cause to be delivered to the Trustee and the
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 Insurer.

<PAGE>   72

            (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 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 Insurer in the related Qualified Replacement
Mortgage are materially and adversely affected; provided, however, that for the
purposes of this subsection (c) the representations and warranties in the
related Master Transfer Agreement or as set forth in Section 3.3 above referring
to items "as of the Cut-Off Date" or "as of the Startup Day" shall be deemed to
refer to such items as of the date such Qualified Replacement Mortgage is
conveyed to the Trust.

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

            (e) Notwithstanding anything to the contrary contained herein, the
Sponsor shall deliver, or cause to be delivered, the File (including the
original Note) for each Mortgage Loan to the Trustee on or before July 6, 1998
or shall repurchase such Mortgage Loan from the Trust (without regard to any
cure period) by remitting the Loan Purchase Price on or before July 6, 1998.

            SECTION 3.5.   CONVEYANCE OF THE MORTGAGE LOANS.

            (a) The Sponsor and its Affiliate, Advanta Conduit Receivables,
Inc., concurrently with the execution and delivery hereof, and on behalf of the
Conduit Acquisition Trust, hereby each transfers, sells, assigns, sets over and
otherwise conveys without recourse, to the Trustee, all right, title and
interest of the Sponsor and Advanta Conduit Receivables, Inc. 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 Insurer. The transfer by the Sponsor and Advanta
Conduit Receivables, Inc. 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 Sponsor and Advanta Conduit
Receivables, Inc.

            (b) The Sponsor agrees to take or cause to be taken such actions and
execute such documents (including, without limitation, the filing of all
necessary continuation statements for the UCC-1 financing statements filed in
the State of New York (which shall have been filed within 90 days of the Startup
Day) describing the Mortgage Loans and naming the Sponsor and Advanta Conduit
Receivables, Inc. 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 Owners' and the Insurer's interests in each Mortgage
Loan and the proceeds thereof.


                                       68
<PAGE>   73

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

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

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

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

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

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

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

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


                                       69
<PAGE>   74

collected and interest accruing on such Qualified Replacement Mortgage on and
after the applicable Replacement Cut-Off Date; provided, however, that the
Sponsor (or the Conduit Acquisition or such affiliate) shall reserve and retain
all right, title and interest in and to payments of principal and interest due
on such Qualified Replacement Mortgage prior to the applicable Replacement
Cut-Off Date.

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

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

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

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

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

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

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

            (a) The Trustee agrees to execute and deliver on the Startup Day an
acknowledgment of receipt in the form attached as Exhibit D hereto of the Files
delivered by the Sponsor, and declares that it will hold such documents and any
amendments, replacement or supplements thereto, as well as any other assets
included in the definition of Trust Estate and delivered to the Trustee, as
Trustee in trust upon and subject to the conditions set forth herein for



                                       70
<PAGE>   75

the benefit of the Owners and the Insurer. On or before the tenth Business Day
after the Startup Day, the Trustee shall execute and deliver to the Insurer and
the Master Servicer an acknowledgement of receipt of the original Notes for each
Mortgage Loan. The Trustee further agrees to review any documents delivered by
the Sponsor within 90 days after the Startup Day (or within 90 days with respect
to any Qualified Replacement Mortgage after the assignment thereof) and to
deliver to the Sponsor, the 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 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 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 Insurer an opinion of
counsel experienced in federal income tax matters stating whether or not such a
proposed purchase or substitution would constitute a Prohibited Transaction for
the Upper-Tier REMIC or Lower-Tier REMIC or would jeopardize the status of the
Upper-Tier REMIC or Lower-Tier REMIC as a REMIC, and the Sponsor shall only be
required to take either such action to the extent such action would not
constitute a Prohibited Transaction for the Upper-Tier REMIC or Lower-Tier REMIC
or would not jeopardize the status of the Upper-Tier REMIC or Lower-Tier REMIC
as a REMIC. Any required purchase or substitution, if delayed by the absence of
such opinion shall nonetheless occur upon the earlier of (i) the occurrence of a
default or imminent default with respect to the Mortgage Loan or (ii) the
delivery of such opinion or (iii) at the direction of the Control Party.

            SECTION 3.7.   COOPERATION PROCEDURES.

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

            (b) The Sponsor, the Master Servicer and the Trustee covenant to
provide each other and to the Insurer with all data and information required to
be provided by them hereunder at the times required hereunder, and additionally
covenant reasonably to cooperate


                                       71
<PAGE>   76

with each other in providing any additional information required by any of them
in connection with their respective duties hereunder.

                        ISSUANCE AND SALE OF CERTIFICATES

            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

deliver the Certificates on behalf of the Trust in accordance with the
directions set forth in such Delivery Order.

            SECTION 4.2.    SALE OF CERTIFICATES. At 11 a.m. New York City
time on the Startup Date, at the offices of Dewey Ballantine, 1301 Sixth
Avenue, New York, New York, the Sponsor will sell and convey the Mortgage Loans

Class F-IO Certificates with an aggregate Percentage Interest in each Class

with an aggregate Percentage Interest equal to 100%, registered as the Sponsor
shall request. Upon receipt of the proceeds of the sale of the Certificates,
the Trustee shall, from the proceeds of the sale of the Certificates, pay other
fees and expenses identified by the Sponsor, and pay to 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 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 Insurance Policy). Distributions on the
Certificates are payable solely from payments received on or with respect to the
Mortgage Loans (other than the Servicing Fees), monies in the Principal and
Interest Account, and the Supplemental Interest Payment Account, except as
otherwise provided herein, from earnings on monies and the proceeds of property
held as a part of the Trust Estate and, from 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 Insured Payments, pro rata in accordance with
such Owner's Percentage Interest and certain amounts payable from the
Supplemental Interest Payment Account.


                                       72
<PAGE>   77

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

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

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

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

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

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

            SECTION 5.4.    REGISTRATION AND TRANSFER OF CERTIFICATES.

            (a) The Trustee, as registrar, shall cause to be kept a register
(the "Register") in which, subject to such reasonable regulations as it may
prescribe, the Trustee shall provide for the registration of Certificates and
the registration of transfer of Certificates. The Trustee is hereby appointed
registrar for the purpose of registering Certificates and transfers of
Certificates as herein provided. The Owners and the 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) At the option of any Owner, Certificates of any Class owned by
such Owner may be exchanged for other Certificates authorized of like Class,
tenor and a like aggregate original principal amount and bearing numbers not
contemporaneously outstanding, upon surrender of the Certificates to be
exchanged at the office designated as the location of the



                                       73
<PAGE>   78

Register. Whenever any Certificate is so surrendered for exchange, the Trustee
shall execute, authenticate and deliver the Certificate or Certificates which
the Owner making the exchange is entitled to receive.

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

            (e) Any Certificate presented or surrendered for registration of
transfer or exchange shall be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Trustee duly executed by the
Owner thereof or his attorney duly authorized in writing.

            (f) No service charge shall be made to an Owner for any registration
of transfer or exchange of Certificates, but the Trustee may require payment of
a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any registration of transfer or exchange of
Certificates; any other expenses in connection with such transfer or exchange
shall be an expense of the Trust.

            (g) It is intended that the Class A Certificates be registered so as
to participate in a global book-entry system with the Depository, as set forth
herein. Each Class of Class A Certificates shall, except as otherwise provided
in the next paragraph, be initially issued in the form of a single fully
registered Class A Certificate with a denomination equal to the Aggregate
Certificate Principal Balance. Upon initial issuance, the ownership of each such
Class A 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 Class A Certificates registered in the Register in
the name of Cede & Co., as nominee of the Depository, the Sponsor, the Master
Servicer, the Insurer and the Trustee shall have no responsibility or obligation
to Direct or Indirect Participants or beneficial owners for which the Depository
holds Class A Certificates from time to time as a Depository. Without limiting
the immediately preceding sentence, the Sponsor, the Master Servicer, the
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 Class A
Certificates, (ii) the delivery to any Direct or Indirect Participant or any
other Person, other than a registered Owner of a Class A Certificate as shown in
the Register, of any notice with respect to the Class A Certificates or (iii)
the payment to any Direct or Indirect Participant or any other Person, other
than a registered Owner of a Class A Certificate as shown in the Register, of
any amount with respect to any distribution of principal or interest on the
Class A Certificates. No Person other than a registered Owner of a Class A
Certificate as shown in the Register shall receive a certificate evidencing such
Class A Certificate.

            Upon delivery by the Depository to the Trustee of written notice to
the effect that the Depository has determined to substitute a new nominee in
place of Cede & Co., and subject to the provisions hereof with respect to the
payment of interest by the mailing of checks or drafts to the registered Owners
of Class A Certificates appearing as registered Owners in the registration



                                       74
<PAGE>   79

books maintained by the Trustee at the close of business on a Record Date, the
name "Cede & Co." in this Agreement shall refer to such new nominee of the
Depository.

            (h) In the event that (i) the Depository or the Sponsor advises the
Trustee and the Insurer in writing that the Depository is no longer willing or
able to discharge properly its responsibilities as nominee and depository with
respect to the Class A Certificates and the 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 Class A 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 Class A 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 Class A Certificates may be registered in whatever
name or names registered Owners of Class A Certificates transferring Class A
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 Class A Certificate is registered in the name of Cede &
Co., as nominee of the Depository, all distributions of principal or interest on
such Class A Certificates as the case may be and all notices with respect to
such Class A Certificates as the case may be shall be made and given,
respectively, in the manner provided in the Representation Letter.

            (j) Neither the Sponsor, the Master Servicer, the 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 Class A Certificates held by Euroclear, CEDEL or Cede & Co., as
nominee for DTC, or for maintaining supervising or reviewing any records
relating to such beneficial ownership interests.

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

            Upon the issuance of any new Certificate under this Section, the
Trustee may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto; any other expenses
in connection with such issuance shall be an expense of the Trust.


                                       75
<PAGE>   80

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

            (b) 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



                                       76
<PAGE>   81

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 Income Security Act of 1974, as amended
("ERISA")) subject to the provisions of Title I of ERISA, (ii) a plan (as
defined in Section 4975(e)(1) of the Code) subject to Section 4975 of the Code,
or (iii) an entity whose underlying assets are deemed to be assets of a plan
described in (i) or (ii) above by reason of such plan's investment in the entity
(each, a "Benefit Plan Entity"). Any transferee of a Class R Certificate shall
(x) certify that it is not any of the above and (y) deliver an opinion of
counsel to that effect.

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

                                   ARTICLE VI

                                    COVENANTS

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


                                       77
<PAGE>   82

            (c) Any money held by the Trustee in trust for the payment of any
amount due with respect to any Class A Certificate and remaining unclaimed by
the Owner of such Class A 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 Insurer on
account of any Reimbursement Amount, and second to the Owners of the Class R
Certificates; and the Owner of such Class A Certificate shall thereafter, as an
unsecured general creditor, look only to the Owners of the Class R Certificates,
or the Insurer for payment thereof (but only to the extent of the amounts so
paid to the 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 Insurer or the Owners of the Class R
Certificates as provided above. The Trustee shall, at the direction of the
Sponsor, also adopt and employ, at the expense of the Sponsor, any other
reasonable means of notification of such payment (including but not limited to
mailing notice of such payment to Owners whose right to or interest in monies
due and payable but not claimed is determinable from the Register at the last
address of record for each such Owner).

            SECTION 6.3.    PROTECTION OF TRUST ESTATE.

            (a) The Trustee will hold the Trust Estate in trust for the benefit
of the Owners and the Insurer as their interests may appear, and, upon request
of the Insurer, or with the consent of the 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
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 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 Class A Certificates then Outstanding or, if there



                                       78
<PAGE>   83

are no longer any affected Class A 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 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
      Agreement, or release any Person from any covenants or obligations with
      respect to the Trust or to the Certificates under this Agreement, except
      as may be expressly permitted hereby or (B) create or extend any lien,
      charge, adverse claim, security interest, mortgage or other encumbrance
      to or upon the Trust Estate or any part thereof or any interest therein
      or the proceeds thereof.

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

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


                                       79
<PAGE>   84

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

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

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

                  (D) the Insurer consented in writing thereto; and

                  (E) no direction inconsistent with such written request has 
            been given to the Trustee during such 60-day period by the Insurer
            or by the Owners of a majority of the Percentage Interests 
            represented by the Class A Certificates or, if there are no Class A
            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 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 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 Insurer or any Owner of any Certificate to exercise any right or
remedy under this Agreement to



                                       80
<PAGE>   85

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 Insurer or to the
Owners may be exercised from time to time, and as often as may be deemed
expedient, by the Trustee, the Insurer or by the Owners, as the case may be.

            SECTION 6.11    CONTROL BY OWNERS. The Insurer (so long as a
Insurer Default has not occurred and is continuing) or the Owners of a majority
of the Percentage Interests represented by the Class A Certificates then
Outstanding, with the consent of the Control Party (which may not be
unreasonably withheld) or, if there are no longer any Class A 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:

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

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

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

            So long as an Insurer Default has not occurred and is continuing,
the Insurer shall act as the Control Party and be subrogated thereto until all
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 paid over to the Trustee by the Master Servicer or by any Sub-Servicer. The
Trustee shall hold all such money and property received by it, other than
pursuant to or as contemplated by Section 6.2(b) hereof, as part of the Trust
Estate and shall apply it as provided in this Agreement.

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



                                       81
<PAGE>   86

benefit of the Owners of the Certificates relating to such Mortgage Loan Group
and the Insurer, as their interests may appear.

            SECTION 7.3.    THE INSURANCE POLICY.

            (a) On each Determination Date the Trustee shall determine with
respect to the immediately following Payment Date the amounts to be on deposit
in each Certificate Account on such Payment Date with respect to each Mortgage
Loan Group (disregarding the amounts of any Insured Payments with respect to
such Mortgage Loan Group) and equal to the sum of (x) such amounts excluding the
amount of any Total Monthly Excess Cashflow amounts included in such amounts and
excluding an amount equal to the Premium Amount with respect to such Mortgage
Loan Group together with any Master Servicing Fees and Trustee's Fees with
respect to such Mortgage Loan Group for the related Payment Date plus (y) any
amounts of Total Monthly Excess Cashflow to be applied on account of such
Mortgage Loan Group on such Payment Date; the amounts described in the preceding
clause (x) with respect to each Mortgage Loan Group and Payment Date, are the
"Available Funds" with respect to such Mortgage Loan Group; the sum of the
amounts described in the preceding clauses (x) and (y) are the "Total Available
Funds" with respect to such Mortgage Loan Group;

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

            (c) The Trustee shall distribute all Insured Payments received, or
the proceeds thereof, in accordance with Section 7.5(b)(F) to the Owners of the
Class A Certificates of the related Class.

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

            Insured Payments disbursed by the Trustee from proceeds of the
Insurance Policy shall not be considered payment by the Trust nor shall such
payments discharge the obligation of the Trust with respect to such insured
Certificates, and the Insurer shall become the owner of such unpaid amounts due
from the Trust in respect of insured Certificates.

            SECTION 7.4.   [RESERVED]

            SECTION 7.5.   FLOW OF FUNDS.

            (a) On each Remittance Date, the Trustee shall deposit to the
Certificate Account with respect to each Mortgage Loan, without duplication,
upon receipt, any Insured Payments relating to such Mortgage Loan Group, the
proceeds of any liquidation of the assets of the Trust, insofar as such assets
relate to such Mortgage Loan Group, together with the Monthly Remittance Amount
with respect to such Mortgage Loan Group remitted by the Master Servicer or any
Sub-servicer.

            (b) Subject to any superseding provisions of clause (e) below during
the continuance of a Insurer Default, on each Payment Date the Trustee shall

deemed acceptable by the Sponsor or the Master Servicer as designated in
writing to the Trustee by an Authorized Officer of the Master Servicer. The
Trust Parties agree not to commence any actions or proceedings, or otherwise
assert any claims, against the Trustee or its affiliates or any of the
Trustee's or its affiliates' respective agents, representatives, directors,
officers or employees (collectively, the "Designated Parties"), arising out of,
or related to or in connection with the dissemination and/or use of any

<PAGE>   98
based on allegations of inaccurate or incomplete information by the Trustee to
Bloomberg or to any Information Network or otherwise (other than in connection
with the Trustee's negligence or willful misconduct). The Trust Parties waive
their rights to assert any such claims against the Designated Parties and fully
and finally release the Designated Parties from any and all such claims,
demands, obligations, actions and liabilities (other than in connection with
such Designated Parties' negligence or willful misconduct). The Trustee makes no
representations or warranties, expressed or implied, of any kind whatsoever with
respect to the accuracy, adequacy, timeliness, completeness, merchantability or
fitness for any particular purpose of any Information in any form or manner. The
authorizations, 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 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 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 Insurer, transmit promptly to the Sponsor, the
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 Insurer and the Master Servicer if any such receipts have not
been received by the Trustee.

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

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

            (a) The parties hereto do hereby create and establish a trust, the
"Advanta Supplemental Interest Trust 1998-2" (the "Supplemental Interest
Trust"). The Supplemental Interest Trust shall hold a trust account, the
"Supplemental Interest Payment Account" to be held by the Trustee in its name on
behalf of the Supplemental Interest Trust. None of the assets of the
Supplemental Interest Trust shall be considered assets of either REMIC, and any
amounts transferred from the Upper-Tier REMIC to the Supplemental Interest Trust
shall be treated as distributions with respect to the Class R Certificates.

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

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


                                       94
<PAGE>   99

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

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

                          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 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 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



                                       95
<PAGE>   100

any Sub-servicer with any powers of attorney and other documents necessary or
appropriate to enable the Master Servicer or any Sub-servicer to carry out its
servicing and administrative duties hereunder.

            (c) Without limiting the generality of the foregoing, the Master 
Servicer (i) shall continue, and is hereby authorized and empowered by the
Trustee, to execute and deliver, on behalf of itself, the Owners, the 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 Insurer and (y) will not cause the Upper-Tier REMIC or the
Lower-Tier REMIC to fail to qualify as a REMIC.

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

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

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

            (g) Without limiting the generality of the foregoing, but subject to
Sections 8.13 and 8.14, the Master Servicer in its own name or in the name of a
Sub-Servicer may be authorized and empowered pursuant to a power of attorney
executed and delivered by the Trustee



                                       96
<PAGE>   101

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

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

            (i) Servicing Advances incurred by the Master Servicer or any 
Sub-Servicer in connection with the servicing of the Mortgage Loans (including
any penalties in connection with the payment of any taxes and assessments or
other charges) on any Property shall be recoverable by the Master Servicer or
such Sub-Servicer to the extent described in Section 8.9(c) and in Section
7.5(b)(E)(3). 

            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 Insurer and the Trustee of the appointment of any Sub-Servicer and
shall furnish to the Insurer and the Trustee a copy of the Subservicing
Agreement. For purposes of this Agreement, the Master shall be deemed to have
received payments on Mortgage Loans when any Sub-Servicer has received such
payments. Any


                                       97
<PAGE>   102

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
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, for each of Group IA, Group IB, Group IIA, and Group IIB, establish in
the name of the Trust for the benefit of the Owners of the Certificates
relating to such Mortgage Loan Group and the Insurer, as their interests may
appear, and maintain at one or more Designated Depository Institutions a
Principal and Interest Account for each such Mortgage Loan Group.



                                       98
<PAGE>   103

            Subject to Subsections (c) and (e) below, the Master Servicer and
any Sub-servicer shall deposit all receipts related to the Mortgage Loans in
each such Mortgage Loan Group to their respective 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 each Principal and Interest
Account all receipts related to the Mortgage Loans in the Mortgage Loan Group
which relate to or are received on or after the Cut-Off Date.

            (b) All funds in the Principal and Interest Account for each 
Mortgage Loan Group may only be held (i) uninvested, up to the limits insured
by the FDIC or (ii) invested in Eligible Investments. The Principal and
Interest Accounts shall be held in trust in the name of the Trust and for the
benefit of the Owners of the Certificates relating to such Mortgage Loan Group
(i.e. in the case of the Principal and Interest Account for Group IA, the Group
IA Certificates, in the case of the Principal and Interest Account for Group
IB, the Group IB Certificates, in the case of the Principal and Interest
Account for Group IIA, the Group IIA Certificates and in the case of the
Principal and Interest Account for Group IIB, the Group IIB Certificates) and
the Insurer. Any investment earnings on funds held in each Principal and
Interest Account shall be for the account of the Master Servicer and may only
be withdrawn from such 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 Accounts 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 each Principal and Interest Account all principal and interest
collections on the Mortgage Loans for the related Mortgage Loan Group 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 such Mortgage Loans,
other recoveries or amounts related to such Mortgage Loans received by the
Master Servicer, Compensating Interest and Delinquency Advances together with
any amounts which are reimbursable from such Principal and Interest Account,
but net of (i) the Servicing Fee with respect to each such Mortgage Loan and
other servicing compensation to the Master Servicer as permitted by Section
8.15 hereof, (ii) principal (including Prepayments) collected on the related
Mortgage Loans prior to the Cut-Off Date, (iii) interest accruing on the
related Mortgage Loans prior to the Cut-Off Date and (iv) Net Liquidation
Proceeds to the extent such Net Liquidation Proceeds exceed the sum of the Loan
Balance of the related Mortgage Loan and accrued and unpaid interest thereon. 

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

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

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

                                       99
<PAGE>   104

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

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

                  (5) to clear and terminate each 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 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(a) of this Agreement. 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, (A) for
      Group IA, the Group IA Interest Remittance Amount and the Group IA
      Principal Remittance Amount, (B) for Group IB, the Group IB Interest
      Remittance Amount and the Group IB Principal Remittance Amount, (C) for
      Group IIA, the Group IIA Interest Remittance Amount and the Group IIA
      Principal Remittance Amount and (D) for Group IIB, the Group IIB Interest
      Remittance Amount and the Group IIB 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 Insurer, the Trustee and each Rating
Agency, then the requirement to maintain the Principal and Interest Accounts
may be waived by an instrument signed by the Insurer, Trustee and each Rating
Agency, and the Master Servicer may be allowed to co-mingle with its general
funds the amounts otherwise required to be deposited to the Principal and
Interest Account, on such terms and subject to such conditions as the Insurer,
the Trustee and each Rating Agency may permit.

            (f) For administrative purposes, each Principal and Interest 
Account may be established as a sub-account of a single account. Amounts on
deposit in all Principal and Interest Accounts may be commingled for purposes
of investment.

            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 



                                      100
<PAGE>   105

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(b)(E)(3) hereof.

            (b) On or prior to each Remittance Date, the Master Servicer shall 
deposit in the Principal and Interest Account with respect to any full
Prepayment received on a Mortgage Loan during the related Remittance Period out
of its own funds without any right of reimbursement therefor, an amount equal
to the difference between (x) 30 days' interest at the Mortgage Loan's Coupon
Rate (less the Servicing Fee) on the Loan Balance of such Mortgage Loan as of
the first day of the related Remittance Period and (y) to the extent not
previously 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(b)(E)(3) 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(b)(E)(3) hereof. 

            (d) On each Remittance Date in June and July of 1998, the Master 
Servicer shall make four Special Advances, one with respect to each Mortgage
Loan Group equal to the sum of (x) one-month's interest, calculated at the
weighted average Pass-Through Rate (applicable to the July or August 1998
Payment Date, as the case may be, for the classes of Class A Certificates
related to such Group) with respect to all Mortgage Loans not having a payment
due during June or July 1998, as the case may be, (y) the Premium Amount with
respect to such Mortgage Loans for the July or August 1998 Payment Date, as the
case may be, and (z) the Trustee's Fee with respect to such Mortgage Loans for
the July or August 1998 Payment Date, as the case may be; the amounts of such
advances shall be included in the related Interest Remittance Amount.
Reimbursement of Special Advances shall be made only as provided in Section
7.5(b)(E)(3). 

            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



                                      101
<PAGE>   106

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 and the Insurer 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 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 Insurer out of the Master Servicer's own funds for any loss
to the Trust and the 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
Insurer, the Master Servicer shall cause to be delivered to the Trustee and the
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



                                      102
<PAGE>   107

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 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 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



                                      103
<PAGE>   108

any REO Property within 35 months of its acquisition by the Trust, unless the
Master Servicer obtains for the Trustee an opinion of counsel experienced in
federal income tax matters, addressed to the Trustee, the 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 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 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 


                                      104
<PAGE>   109

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 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 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 Property
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.

                                      105
<PAGE>   110

            (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 Insurer and the Rating Agencies pursuant to Section 3.5(j) hereof. 

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

            On each day that the Master Servicer remits to the Trustee Master
Servicer's Trust Receipts pursuant to clauses (ii) or (iii) above, the Master
Servicer or any Sub-servicer shall also submit to the Trustee a summary of the
total amount of such Master Servicer's Trust Receipts requested on such day by
the same method as described in such clauses (ii) or (iii) above.

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

            SECTION 8.16.   ANNUAL STATEMENT AS TO COMPLIANCE. The Master 
Servicer, at its own expense, will deliver to the Trustee, the Insurer and each
Rating Agency, on or before the last day of March of each year, commencing in
1999, 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 1999,
the Master Servicer, at its own expense, shall cause to be delivered to the
Trustee, the Insurer and each Rating Agency a letter or letters of a firm of
independent, nationally recognized certified public accountants 


                                      106
<PAGE>   111

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 Insurer, the FDIC and the supervisory agents and examiners of each of the
foregoing access to the documentation regarding the Mortgage Loans required by
applicable state and federal regulations, such access being afforded without
charge but only upon reasonable request and during normal business hours at the
offices of the Master Servicer designated by it.

            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 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 Insurer and Moody's.

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

            (a) The Trustee, with the consent of the 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
      appointment of a receiver, trustee, liquidator or custodian or similar

      inability to pay its debts generally as they become due, (iii) make a
      general assignment for the benefit of creditors, (iv) be adjudicated a

      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

                                      107
<PAGE>   112

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

            (iv) The Master Servicer shall fail to perform any one or more of
      its obligations hereunder other than the obligations contemplated by
      Subsection 8.20(i) above, and shall continue in default thereof for a
      period of sixty (60) days after notice by the Trustee or the 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 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 Certificate Insurer also may remove the Master Servicer 
upon the occurrence of any of the following events:

            (i) upon the making of any Insured Payment; provided, however, that
      the 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 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 Insurer and
      the Trustee; or 

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

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

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

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


                                      108
<PAGE>   113

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
Special Advance or to pay any Compensating Interest or Monthly Remittance, such
removal shall be effective (without the requirement of any action on the part of
the Insurer or of the Trustee) at 4 p.m. on the second Business Day following
the day on which the Trustee or the Insurer notifies an Authorized Officer of
the Master Servicer that a required Delinquency Advance or Special Advance has
not been received by the Trustee. Upon the Trustee's determination that a
required Delinquency Advance or Special Advance or payment of Compensating
Interest has not been made by the Master Servicer, the Trustee shall so notify
in writing an Authorized Officer of the Master Servicer and the 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 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


                                      109
<PAGE>   114

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 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 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 

                                      110
<PAGE>   115

Delinquency Advances described in this clause (j)) if, in the Trustee's
reasonable good faith judgment, such Delinquency Advances will ultimately be
recoverable from the related Mortgage Loans.

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

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

            (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 INSURER AND THE TRUSTEE; ERRORS 
AND OMISSIONS INSURANCE.

            (a) At any reasonable time and from time to time upon reasonable 
notice, the 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 upon notice to the Insurer, 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 is a 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.

            SECTION 8.23.   NOTICES OF MATERIAL EVENTS. The Master Servicer

<PAGE>   116

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

            (c) The receipt of notice from any agency or governmental body 
having authority over the conduct of any of the Sponsor's the Master Servicer's

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

                                   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 Insurance Policy of all amounts held by the Trustee
and required to be paid to such Owners pursuant to this Agreement upon the
later to occur of (a) the final payment or other liquidation (or any advance
made with respect thereto) of the last Mortgage Loan in the Trust Estate or (b)
the disposition of all property acquired in respect of any Mortgage Loan
remaining in the Trust Estate, (ii) at any time when a Qualified Liquidation of
the REMIC Trust is effected as described below or (iii) as described in Section
9.2 or 9.3 hereof. To effect a termination of this Agreement pursuant to clause
(ii) above, the Owners of all Certificates then Outstanding shall (x)
unanimously direct the Trustee on behalf of the Lower-Tier REMIC and the
Upper-Tier REMIC to adopt a plan of complete liquidation with respect to each
of the Mortgage Loan Groups as contemplated by Section 860F(a)(4) of the Code
and (y) provide to the Trustee an opinion of counsel experienced in federal
income tax matters to the effect that such liquidation constitutes a Qualified
Liquidation, and the Trustee either shall sell the Mortgage Loans and
distribute the proceeds of the liquidation of the Trust Estate, or shall
distribute equitably in kind all of the assets of the Trust Estate to the
remaining Owners of the Certificates based on their interests in the Trust, and
distribute to the Insurer any amounts owed under the Insurance Agreement and
return the Insurance Policy to the Insurer, 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


                                      112
<PAGE>   117

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 all of the Mortgage Loans as of the
day of purchase minus the amount actually remitted by the Master Servicer
representing the related Monthly Principal Remittance Amount on such Remittance
Date for the related Remittance Period and (ii) the fair market value of such
Mortgage Loans (disregarding accrued interest), (w) the amount of any difference
between the related Monthly Interest Remittance Amount actually remitted by the
Master Servicer on such Remittance Date and the related Monthly Interest
Remittance Amount due on such Remittance Date, (x) the related Group II
Reimbursement Amount, if any, and (y) the aggregate amount of any Delinquency
Advances and Servicing Advances remaining unreimbursed, together with any
accrued and unpaid Servicing Fees, as of such Remittance Date (such amount, the
"Termination Price"). In connection with such purchase, the Master Servicer
shall remit to the Trustee all amounts then on deposit in the Principal and
Interest Account for deposit to the Certificate Account, which deposit shall be
deemed to have occurred immediately preceding such purchase. Notwithstanding the
foregoing, the Master Servicer or its affiliate may not terminate the Trust
pursuant to this Section 9.2 without the consent of the Insurer, if termination
would result in a draw on the Insurance Policy. 

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

            (c) Promptly following any such purchase, the Trustee will release 
the Files to the Master Servicer, or otherwise upon their order, in a manner
similar to that described in Section 8.14 hereof. (d) Upon such purchase, the
Insurance Policy will terminate and shall be returned to the Insurer. 

            SECTION 9.3.   TERMINATION UPON LOSS OF REMIC STATUS.

            (a) Following a (x) final determination by the Internal Revenue 
Service, or by a court of competent jurisdiction, in either case from which no
appeal is taken within the permitted time for such appeal, or (y) if any appeal
is taken, following a final determination of such appeal from which no further
appeal can be taken, to the effect that either the Upper-Tier REMIC or
Lower-Tier REMIC do not and will no longer qualify as a "REMIC" pursuant to
Section 860D of the Code (the "Final Determination") or (z) following the
delivery of an opinion of counsel ("REMIC Opinion") to the effect that the
effect of the Final Determination is to increase substantially the probability
that either the Upper-Tier REMIC or Lower-Tier REMIC will no longer qualify as
a "REMIC" pursuant to Section 860D of the Code, on any Remittance Date on or
after the date which is 30 calendar days following such Final Determination,
the Owners of a majority in Percentage Interest represented by the Class A
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 Class A
Certificates or such notice from the Insurer, the Trustee shall notify the
holders of the Class R


                                      113
<PAGE>   118

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

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

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

                                 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. 

            (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 Insurer or of the Owners of a majority in Percentage
      Interest of the Certificates of the affected Class or Classes and the
      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.

any order, rule or regulation of any administrative or governmental body):

            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
            or certified mail, to the Trustee by the Sponsor, the Insurer or by
            the Owners of at least 25% of the aggregate Percentage Interests

                  (D) a conservator or receiver or liquidator or sequestrator 
            or custodian of the property of the Trustee is 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

                  (E) 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 advantage of any
            applicable insolvency or reorganization statute, make an assignment
            for the benefit of its creditors, voluntarily suspend payment of
            its obligations, or take corporate action for the purpose of any of

                                      118
<PAGE>   123

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 Insurer) (which consent shall not be
unreasonably withheld) or of the 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
Insurer and the Owners at their addresses appearing on the Register. A copy of
such notice shall be sent by the resigning Trustee to each Rating Agency. Upon
receiving notice of resignation, the Sponsor shall promptly appoint a successor
trustee or trustees by written instrument, in duplicate, executed on behalf of
the Trust by an Authorized Officer of the Sponsor, one copy of which instrument
shall be delivered to the Trustee so resigning and one copy to the successor
trustee or trustees. If no successor trustee shall have been appointed and have
accepted appointment within 30 days after the giving of such notice of
resignation, the resigning trustee may petition any court of competent
jurisdiction for the appointment of a successor trustee, or any Owner may, on
behalf of himself and all others similarly situated, petition any such court for
the appointment of a successor trustee. Such court may thereupon, after such
notice, if any, as it may deem proper and prescribe, appoint a successor
trustee.

            (c) If at any time the Trustee shall cease to be eligible under 
Section 10.8 hereof and shall fail to resign after written request therefor by
the Sponsor or by the Insurer, the Insurer or the Sponsor (with the written
consent of the 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 Class A Certificates, or, if there are no Class A
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 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 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
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 Insurer and the Sponsor duly
authorized, one complete set of which instruments shall be delivered to the
Sponsor, one complete set to the


                                      119
<PAGE>   124


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
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
Class A Certificates then Outstanding or, if there are no Class A 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. 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
Insurer and to the Owners as their names and addresses appear in the Register.
Each notice shall include the name of the successor Trustee and the address of
its corporate trust office.

            SECTION 10.10.   ACCEPTANCE OF APPOINTMENT BY SUCCESSOR TRUSTEE. 
Every successor Trustee appointed hereunder shall execute, acknowledge and
deliver to the Sponsor on behalf of the Trust and to its predecessor Trustee an
instrument accepting such appointment hereunder and stating its eligibility to
serve as Trustee hereunder, and thereupon the resignation or removal of the
predecessor Trustee shall become effective and such successor Trustee, without
any further act, deed or conveyance, shall become vested with all the rights,
powers, trusts, duties and obligations of its predecessor hereunder; but, on
request of the Sponsor or the successor Trustee, such predecessor Trustee
shall, upon payment of its charges then unpaid, execute and deliver an
instrument transferring to such successor Trustee all of the rights, powers and
trusts of the Trustee so ceasing to act, and shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such Trustee
so ceasing to act hereunder. Upon request of any such successor Trustee, the
Sponsor on behalf of the Trust shall execute any and all instruments for more
fully and certainly vesting in and confirming to such successor Trustee all
such rights, powers and trusts.

            Upon acceptance of appointment by a successor Trustee as provided in
this Section, the Sponsor shall mail notice thereof by first-class mail, postage
prepaid, to the Owners at their last addresses appearing upon the Register. The
Sponsor shall send a copy of such notice to each of the Rating Agencies and the
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



                                      120
<PAGE>   125

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.

            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 and is otherwise liable). 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 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



                                      121
<PAGE>   126

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 Insurer. No co-Trustee or separate Trustee hereunder shall be required to
meet the terms of eligibility as a successor Trustee under Section 10.8 and no
notice to Owner of the appointment of any co-Trustee or separate Trustee shall
be required under Section 10.8.

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

            (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 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 Insurer or the Owners to the Trustee
to take any action under any provision of this Agreement, the Sponsor, the
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 



                                      123
<PAGE>   128

that such counsel believes that such counsel and the Trustee may reasonably rely
upon the opinion of such other counsel.

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

            SECTION 11.3.   ACTS OF OWNERS.

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



                                      124
<PAGE>   129

mailed in the manner provided above, neither the failure to mail such notice or
report nor any defect in any notice or report so mailed to any particular Owner
shall affect the sufficiency of such notice or report with respect to other
Owners, and any notice or report which is mailed in the manner herein provided
shall be conclusively presumed to have been duly given or provided.

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

            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 Insurer and the parties hereto and their successors
hereunder, any benefit or any legal or equitable right, remedy or claim under
this Agreement.

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

            SECTION 11.11.   GOVERNING LAW. In view of the fact that Owners 
are expected to reside in many states and outside the United States and the
desire to establish with certainty that this Agreement will be governed by and
construed and interpreted in accordance with the law



                                      125
<PAGE>   130

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.

            (a) The Trustee, the Sponsor and the Master Servicer, may at any 
time and from time to time, with the prior written consent of the 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 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 IA Specified
Overcollateralization Amount," "Group IB Specified Overcollateralization
Amount," "Group IIA Specified Overcollateralization Amount" and "Group IIB
Specified Overcollateralization Amount"; provided, however, that no such change
shall affect the weighted average life of the related Class of Class A
Certificates (assuming an appropriate prepayment speed as determined by the
Representative) by more than five percent, as determined by the Representative. 



                                      126
<PAGE>   131

            (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 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
Class A 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 Insurer to the effect that such amendment
would not adversely affect the status of either the Upper-Tier REMIC or
Lower-Tier REMIC as a REMIC. Neither such opinion of counsel nor any expense of
any such proposed amendment shall be at the Trustee's expense. 

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

            SECTION 11.15 REMIC STATUS; TAXES.

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

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



                                      127
<PAGE>   132

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 Upper-Tier REMIC and
Lower-Tier REMIC, (ii) not to engage in any "prohibited transaction", as such
term is defined in Section 860F(a)(2) of the Code and (iii) not to engage in
any other action which may result in the imposition on the Upper-Tier REMIC and
Lower-Tier REMIC of any other taxes under the Code.

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

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

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

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

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

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

                                      128
<PAGE>   133


            (b) In the event that any tax is imposed on "prohibited 
transactions" of either the Upper-Tier REMIC or Lower-Tier REMIC as defined in
Section 860F(a)(2) of the Code, on the "net income from foreclosure property"
as defined in Section 860G(c) of the Code, on any contribution to either the
Upper-Tier REMIC or Lower-Tier REMIC after the Startup Day pursuant to Section
860G(d) of the Code, or any other tax (other than any minimum tax imposed by
Sections 23151(a) or 23153(a) of the California Revenue and Taxation Code) is
imposed, such tax shall be paid by (i) the Trustee, if such tax arises out of
or results from a breach by the Trustee of any of its obligations under this
Agreement, (ii) the Master Servicer, if such tax arises out of or results from
a breach by the Master Servicer of any of its obligations under this Agreement,
or otherwise (iii) the Owners of the Lower-Tier Residual Class and the Class R
Certificates in proportion to their Percentage Interests. To the extent such
tax is chargeable against the Owners of the Lower-Tier Residual Class and the
Class R Certificates, notwithstanding anything to the contrary contained
herein, the Trustee is hereby authorized to retain from amounts otherwise
distributable to the Owners of the Class R Certificates on any Payment Date
sufficient funds to reimburse the Trustee for the payment of such tax (to the
extent that the Trustee has not been previously reimbursed or indemnified
therefor). 

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

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

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

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

      contemplated by this Agreement and the conveyance Agreements on the part
      of such Affiliated Originator and the performance by such Affiliated
      Originator of its obligations under this Agreement and such of the
      Conveyance Agreements to which it is a party. 

            (x) The origination practices used by such Affiliated Originator

      Originator have been, (i) in all material respects, legal, proper, prudent
      and customary in the mortgage loan lending business and (ii) in compliance
      with the Servicer's underwriting criteria as described in the Prospectus.

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

      laws or any similar statutory provisions in effect in any applicable
      jurisdiction.

            (xii) Such Affiliated Originator received fair consideration and
      reasonably equivalent value in exchange for the sale of the interests in
      the Mortgage Loans. 

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

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

            (b)   The Sponsor hereby represents and warrants to each Affiliated

            violate the organization documents of the Sponsor, contravene or
            violate any law, regulation, rule, order, judgement or decree to
            which the Sponsor or its properties are subject or contravene,
            violate or result in any breach of any provision of, or constitute a
            default under, or result in the imposition of any lien on any assets
            of the Sponsor pursuant to the provisions of, any mortgage,
            indenture, contract, agreement or other undertaking to which the
            Sponsor is a party or which purports to be binding upon Sponsor or
            any of Sponsor's assets; this Agreement evidences the valid and
            binding obligation of the Sponsor enforceable against the Sponsor in
            accordance with its terms, subject to the effect of bankruptcy,
            insolvency, reorganization, moratorium and other similar laws

            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

            this Agreement; and 

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

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

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)

            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

            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 


                                       8
<PAGE>   11
            respect to the related Mortgage Loan, which exceptions are generally
            acceptable to banking institutions in connection with their regular
            mortgage lending activities, and such other exceptions to which
            similar properties are commonly subject and which do not
            individually, or in the aggregate, materially and adversely affect
            the benefits of the security intended to be provided by such
            Mortgage;

                  (vii) Immediately prior to the transfer and assignment herein
            contemplated, each Affiliated Originator held good and indefeasible

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

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

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

                  (x) There is no valid and enforceable right of rescission
            offset, defense or counterclaim to any Note or Mortgage, including
            the obligation of the related Mortgagor to pay the unpaid principal
            of or interest on such Note or the defense of usury, nor will the
            operation of any of the terms of the Mortgage Note or the Mortgage,
            or the exercise of any right thereunder, render either the Mortgage
            Note or the Mortgage unenforceable in whole or in part, or subject
            to any right of rescission, set-off, counterclaim or defense,
            including the defense of usury, and no such right of rescission,
            set-off, counterclaim or defense has been asserted with respect
            thereto; 

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

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

            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

                  (xiv) The improvements upon each Property are covered by a
            valid and existing hazard insurance policy (which may be a blanket
            policy of the type described in the related Advanta Pooling
            Agreement) with a generally acceptable carrier that provides for
            fire and extended coverage representing coverage not less than the
            least of (A) the outstanding principal balance of the related
            Mortgage Loan (together, in the case of a Second Mortgage Loan, with
            the outstanding principal balance of the Senior Lien), (B) the

                  (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; 


                                       10

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

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

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

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

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

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

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

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

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


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

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

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

                  (xxix) No improvement located on or being part of any Property
            is in violation of any applicable zoning law or regulation. All
            inspections, licenses and certificates required to be made or issued
            with respect to all occupied portions of each Property and, with
            respect to the use and occupancy of the same, including but not
            limited to certificates of occupancy and fire underwriting
            certificates, have been made or obtained from the appropriate
            authorities and such Property is lawfully occupied under the
            applicable law; 

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


                                       12
<PAGE>   15
            (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

                  (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

AMBAC ASSURANCE CORPORATION (AMBAC) A Wisconsin Stock Insurance Company in
consideration of the payment of the premium and subject to the terms of this
Policy, hereby agrees unconditionally and irrevocably to pay to the Trustee for
the benefit of the Holders of the Insured Obligations, that portion of the
Insured Amounts which shall become Due for Payment but shall be unpaid by reason
of Nonpayment.

Ambac will make such payments to the Trustee from its own funds on the later of
(a) one (1) Business Day following notification to Ambac of Nonpayment or (b)
the Business Day on which the Insured Amounts are Due for Payment. Such payments
of principal or interest shall be made only upon presentation of an instrument
of assignment in form and substance satisfactory to Ambac, transferring to Ambac
all rights under such Insured Obligations to receive the principal of and
interest on the Insured Obligation. Ambac shall be subrogated to all the
Holders' rights to payment on the Insured Obligations to the extent of the
insurance disbursements so made. Once payments of the Insured Amounts have been
made to the Trustee, Ambac shall have no further obligation hereunder in respect
of such Insured Amounts.

In the event the Trustee for the Insured Obligations has notice that any payment
of principal or interest on an Insured Obligation which has become Due for
Payment and which is made to a Holder by or on behalf of the Trustee has been
deemed a preferential transfer and theretofore recovered from its Holder
pursuant to the United States Bankruptcy Code in accordance with a final,
unappealable order of a court of competent jurisdiction, such Holder will be
entitled to payment from Ambac to the extent of such recovery if sufficient
funds are not otherwise available.

This policy in noncancelable by Ambac for any reason, including failure to
receive payment of any premium due hereunder. The premium on this Policy is not
refundable for any reason. This Policy does not insure against loss of any
prepayment or other acceleration payment which at any time may become due in
respect of any Insured Obligation, other than at the sole option of Ambac, nor
against any risk other than Nonpayment, including failure of the Trustee to make
any payment due Holders of Insured Amounts.

To the fullest extent permitted by applicable law, Ambac hereby waives and
agrees not to assert any and all rights and defenses, to the extent such rights
and defenses may be available to Ambac, to avoid payment of its obligations
under this Policy in accordance with the express provisions hereof.

All capitalized terms not defined herein shall have the meaning given such terms
in the endorsement attached hereto or in the Agreement.

In witness whereof, Ambac has caused this Policy to be affixed with its
corporate seal and to be signed by its duly authorized officers in facsimile to
become effective as their original signatures and binding upon Ambac by virtue
of the countersignature of its duly authorized representative.
