(for itself and the other Underwriter
named in Schedule I hereto)

Ladies and Gentlemen:

      Advanta Conduit Receivables, Inc., as Sponsor (the "Sponsor"), has
authorized the issuance and sale of Advanta Revolving Home Equity Loan
Asset-Backed Notes, Series 1999-B (the "Notes"). The Notes will be issued
pursuant to an indenture (the "Indenture"), dated as of September 1, 1999,
between Advanta Revolving Home Equity Loan Trust 1999-B (the "Trust") and
Bankers Trust Company of California, N.A., as Indenture Trustee (the "Indenture
Trustee"). The Trust will be formed pursuant to a trust agreement (the "Trust
Agreement"), dated as of September 1, 1999, among the Sponsor, Advanta Holding
Trust 1999-B ("Holding") and Wilmington Trust Company, as Owner Trustee. The
Notes will be secured by certain adjustable rate home equity revolving credit
line loans (the "Mortgage Loans") made pursuant to certain home equity revolving
credit line loan agreements (the "Credit Line Agreements") to be transferred or
caused to be transferred by the Sponsor to Holding and by Holding to the Trust
pursuant to a sale and servicing agreement (the "Sale and Servicing Agreement"),
dated as of September 1, 1999, among the Sponsor, Holding, the Trust, Advanta
Mortgage Corp. USA, as Master Servicer (the "Master Servicer"), and the
Indenture Trustee. The beneficial ownership interests of Holding will initially
be held by Advanta National Bank (the "Bank") and Advanta Finance Residual Corp.
("AFRC"), a special-purpose finance subsidiary of Advanta Finance Corp. ("AFC"
together with the Bank, the "Originators"). Such beneficial ownership interests
in Holding will represent the remaining undivided interest in the assets of the
Trust (the "Residual Interest"), and may be sold or pledged at any
   2
time, subject to certain conditions specified in the Trust Agreement. The Notes
will be issued on or about September 28, 1999 (the "Closing Date") in the
aggregate original principal amount of $275,000,000. The Notes and the Residual
Interest are more fully described in a registration statement which the Sponsor
has furnished or will furnish to the underwriters named in Schedule I hereto
(the "Underwriters").

      On or prior to the date of issuance of the Notes, the Sponsor will obtain
a guaranty insurance policy (the "Policy") issued by Ambac Assurance Corporation
(the "Insurer"), which will unconditionally and irrevocably guarantee to the
Indenture Trustee for the benefit of the Noteholders the timely payment of
interest on and ultimate payment of principal of the Notes, excluding certain
amounts as specified in the Documents (as defined below). Concurrently
therewith, the Sponsor will enter into an Insurance and Indemnity Agreement (the
"Insurance Agreement"), dated as of September 28, 1999 among the Sponsor, the
Insurer, the Master Servicer, Holding, the Trust, the Indenture Trustee and the
Owner Trustee, governing certain matters relating to the issuance of the Policy.
The Sponsor will also enter into an Indemnification Agreement, dated as of
September 28, 1999 (the "Indemnification Agreement"), among the Sponsor, the
Underwriters and the Insurer.

      As used herein, the "Documents" shall mean the Indenture, the Trust
Agreement, the Holding Trust Agreement, the Sale and Servicing Agreement, the
Underwriting Agreement, the Insurance Agreement and the Indemnification
Agreement. Capitalized terms used but not defined herein shall have the meanings
given to them in the Sale and Servicing Agreement.

            SECTION 1. Representations and Warranties of the Sponsor  The
Sponsor represents and warrants to, and agrees with each Underwriter that:

            A. The Sponsor has filed with the Securities and Exchange Commission
      (the "Commission"), a registration statement (No. 333-75295) on Form S-3
      for the registration under the Securities Act of 1933, as amended (the
      "Act"), of Mortgage Loan Asset Backed Certificates and Notes (issuable in
      series), which registration statement, as amended at the date hereof, has
      become effective. Such registration statement, as amended to the date of
      this Agreement, meets the requirements set forth in Rule 415(a)(1)(vii)
      under the Act and complies in all other material respects with such Rule.
      The Sponsor proposes to file with the Commission pursuant to Rule
      424(b)(3) under the Act a preliminary prospectus supplement dated
      September 15, 1999 and pursuant to Rule 424(b)(2), a prospectus supplement
      dated September 21, 1999 to the prospectus dated August 10, 1999 relating
      to the Notes and the method of distribution thereof and has previously
      advised or will advise you of all further information (financial and
      other) with respect to the Notes to be set forth therein. Such
      registration statement, including the exhibits thereto, as amended at the
      date hereof, is hereinafter called the "Registration Statement"; such
      prospectus dated August 10, 1999, in the form in which it will be filed
      with the Commission pursuant to Rule 424(b) under the Act is hereinafter
      called the "Basic Prospectus"; such preliminary prospectus supplement
      dated September 15, 1999, in the form in


                                       2
   3
      which it will be filed with the Commission pursuant to Rule 424(b)(3)
      under the Act is hereinafter called the "Preliminary Prospectus
      Supplement"; such prospectus supplement dated September 21, 1999 to the
      Basic Prospectus, in the form in which it will be filed with the
      Commission pursuant to Rule 424(b)(2) of the Act, is hereinafter called
      the "Prospectus Supplement"; and the Basic Prospectus, the Preliminary
      Prospectus Supplement and the Prospectus Supplement together are
      hereinafter called the "Prospectus." The Sponsor will file with the
      Commission (i) promptly after receipt from each Underwriter of any
      Computational Materials (as defined herein) (and in any event no later
      than the Business Day on which the Prospectus Supplement is made available
      to the Underwriter), a Form 8-K incorporating such Computational Materials
      and (ii) within fifteen days of the issuance of the Notes a report on Form
      8-K setting forth specific information concerning the related Mortgage
      Loans (the "8-K").

            B. The Registration Statement conforms, and the Prospectus and any
      further amendments or supplements to the Registration Statement or the
      Prospectus will, when they become effective or are filed with the
      Commission, as the case may be, conform in all respects to the
      requirements of the Act and the rules and regulations of the Commission
      thereunder. The Registration Statement, as of the Effective Date thereof
      and of any amendment thereto, did not contain an untrue statement of a
      material fact or omit to state a material fact required to be stated
      therein or necessary to make the statements therein not misleading. The
      Prospectus, as of its date and as amended or supplemented as of the
      Closing Date (as hereinafter defined), does not and will not contain any
      untrue statement of a material fact or omit to state a material fact
      necessary in order to make the statements therein, in the light of the
      circumstances under which they were made, not misleading; provided,
      however, that no representation or warranty is made as to information
      contained in or omitted from the Registration Statement or the Prospectus
      in reliance upon and in conformity with written information furnished to
      the Sponsor in writing by the Underwriters expressly for use therein. As
      used in this Agreement, "Effective Time" means the date and the time as of
      which such Registration Statement, or the most recent post-effective
      amendment thereto, if any, was declared effective by the Commission;
      "Effective Date" means the date of the Effective Time.

            C. The documents incorporated by reference in the Prospectus, when
      they became effective or were filed with the Commission, as the case may
      be, conformed in all material respects to the requirements of the Act or
      the Securities Exchange Act of 1934, as amended (the "Exchange Act"), as
      applicable, and the rules and regulations of the Commission thereunder,
      and none of such documents contained an untrue statement of a material
      fact or omitted to state a material fact required to be stated therein or
      necessary to make the statements therein not misleading; and any further
      documents so filed and incorporated by reference in the Prospectus, when
      such documents become effective or are filed with the Commission, as the
      case may be, will conform in all material respects to the requirements of
      the Act or the Exchange Act, as applicable, and the rules and regulations
      of the Commission thereunder and will not contain an untrue


                                       3
   4
      statement of a material fact or omit to state a material fact required to
      be stated therein or necessary to make the statements therein not
      misleading.

            D. Since the respective dates as of which information is given in
      the Prospectus, there has not been any material adverse change in the
      general affairs, management, financial condition, or results of operations
      of the Sponsor, except as set forth or contemplated in the Prospectus as
      supplemented or amended as of the Closing Date.

            E. The Sponsor has been duly incorporated and is validly existing as
      a corporation in good standing under the laws of its jurisdiction of
      incorporation, is duly qualified to do business and is in good standing as
      a foreign corporation in each jurisdiction in which its ownership or lease
      of property or the conduct of its business requires such qualification,
      and has all power and authority necessary to own or hold its properties,
      to conduct the business in which it is engaged and to enter into and
      perform its obligations under the Documents to which it is a party, and to
      cause the Notes to be issued.

            F. There are no actions, proceedings or investigations pending
      before or threatened by any court, administrative agency or other tribunal
      to which the Sponsor is a party or of which any of its properties is the
      subject (a) which if determined adversely to the Sponsor would have a
      material adverse effect on the business or financial condition of the
      Sponsor, (b) which asserts the invalidity of the Documents or the Notes,
      (c) which seeks to prevent the issuance of the Notes or the consummation
      by the Sponsor of any of the transactions contemplated by the Documents to
      which it is a party or (d) which might materially and adversely affect the
      performance by the Sponsor of its obligations under, or the validity or
      enforceability of, the Documents to which it is a party or the Notes.

            G. The Documents, when executed and delivered as contemplated hereby
      and thereby, will have been duly authorized, executed and delivered by the
      Sponsor and will constitute legal, valid and binding instruments
      enforceable against the Sponsor, subject as to enforceability to (x)
      applicable bankruptcy, reorganization, insolvency, moratorium or other
      similar laws affecting creditors' rights generally, (y) general principles
      of equity (regardless of whether enforcement is sought in a proceeding in
      equity or at law) and (z) with respect to rights of indemnity under this
      Agreement, the Indemnification Agreement and the Insurance Agreement,
      limitations of public policy under applicable securities laws.

            H. The execution, delivery and performance of the Documents by the
      Sponsor and the consummation of the transactions contemplated hereby and
      thereby, and the issuance and delivery of the Notes do not and will not
      conflict with or result in a breach or violation of any of the terms or
      provisions of, or constitute a default under, any indenture, mortgage,
      deed of trust, loan agreement or other agreement or instrument to which
      the Sponsor is a party, by which the Sponsor is bound or to which any of
      the property or assets of the Sponsor or any


                                       4
   5
      of their respective subsidiaries are subject, nor will such actions result
      in any violation of the provisions of the articles of incorporation or
      by-laws of the Sponsor or any statute or any order, rule or regulation of
      any court or governmental agency or body having jurisdiction over the
      Sponsor or any of their respective properties or assets.

            J. The direction by the Sponsor to the Indenture Trustee to execute,
      authenticate, issue and deliver the Notes has been or will be duly
      authorized by the Sponsor, and assuming the Indenture Trustee has been
      duly authorized to do so, when executed, authenticated, issued and
      delivered by the Indenture Trustee in accordance with the Indenture, the
      Notes will be validly issued and outstanding and will be entitled to the
      benefits provided by the Indenture.

            K. No consent, approval, authorization, order, registration or
      qualification of or with any court or governmental agency or body of the
      United States is required for the issuance of the Notes and the sale of
      the Notes to the Underwriters, or the consummation by the Sponsor of the
      other transactions contemplated by the Documents, except such consents,
      approvals, authorizations, registrations or qualifications as may be
      required under State securities or "blue sky" laws in connection with the
      purchase and distribution of the Notes by the Underwriters or as have been
      obtained.

            L. At the time of execution and delivery of the Sale and Servicing
      Agreement, the Sponsor will or cause the Trust to: (i) have good title to
      the interest in the Mortgage Loans and the other rights and properties to
      be conveyed by the Sponsor thereunder, free and clear of any lien,
      mortgage, pledge, charge, encumbrance, adverse claim or other security
      interest (collectively, "Liens"); (ii) except as provided in the
      Documents, not have assigned to any person any of its right, title or

      Mortgage Loans (excluding any payments of interest collected prior to the
      Cut-Off Date). Upon delivery to the Underwriters of the Notes, the
      Underwriters will have good title to the Notes, free of any Liens.

      or threatened by the Commission. Any request of the Commission for
      inclusion of additional information in the Registration Statement or the
      Prospectus shall have been complied with.

            B. The Underwriters shall not have discovered and disclosed to the
      Sponsor on or prior to the Closing Date that the Registration Statement or
      the Prospectus or any amendment or supplement thereto contains an untrue
      statement of a fact or omits to state a fact which, in the opinion of
      Brown & Wood 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 the Documents, the Notes, the
      Registration Statement and the Prospectus, and all other legal matters
      relating to this Agreement and the transactions contemplated hereby shall
      be satisfactory in all respects to counsel for the Underwriters, and the
      Sponsor shall have furnished to such counsel all documents and information
      that they may reasonably request to enable them to pass upon such matters.


                                       9
   10
            D. The Underwriters shall have received the favorable opinion of
      Dewey Ballantine LLP, special counsel to the Sponsor with respect to the
      following items, dated the Closing Date, to the effect that:

            1. The Sponsor has been duly organized and is validly existing as a
      corporation in good standing under the laws of its jurisdiction of
      incorporation, and is qualified to do business in each state necessary to
      enable it to perform its obligations as Sponsor under the Documents to
      which it is a party. The Sponsor has the requisite power and authority to
      execute and deliver, engage in the transactions contemplated by, and
      perform and observe the conditions of the Documents to which it is a
      party.

            2. The Documents to which the Sponsor is a party have been duly and
      validly authorized, executed and delivered by the Sponsor and all
      requisite corporate action by the Sponsor has been taken with respect
      thereto, and the Notes constitute the valid, legal and binding agreement
      of the Trust.

            3. Neither the transfer of the Mortgage Loans to the Trust, the
      issuance or sale of the Notes nor the execution, delivery or performance
      by the Sponsor of the Documents to which it is a party (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 by-laws of the Sponsor; (ii) any
      term or provision of any material agreement, contract, instrument or
      indenture, to which the Sponsor 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 Sponsor and known to such counsel; or (B) results in, or will
      result in the creation or imposition of any lien, charge or encumbrance
      upon any of the Trust's assets or upon the Notes, except as otherwise
      contemplated by the Sale and Servicing Agreement.

            4. With respect to the Mortgage Loans, the endorsement and delivery
      of each Credit Line Agreement, and the preparation, delivery and recording
      of an Assignment, in each case with respect to each Mortgage, is
      sufficient to fully transfer to the Indenture Trustee for the benefit of
      the Noteholders all right, title and interest of the Sponsor or its
      affiliates in the Credit Line Agreement 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 Indenture Trustee to avail
      itself of all protection available under applicable law against the claims
      of any present or future creditors of the Sponsor and to prevent any other
      sale, transfer, assignment, pledge or other encumbrance of the Mortgage
      Loans by the Sponsor from being enforceable, subject to any exceptions set
      forth in such opinion.

            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


                                       10
   11
      performance of the Documents or the offer, issuance, sale or delivery of
      the Notes or the consummation of any other transaction contemplated
      thereby by the Sponsor, except such which have been obtained.

            6. There are no actions, proceedings or investigations, to such
      counsel's knowledge, pending or threatened against the Sponsor before any
      court, governmental agency or body or other tribunal (i) asserting the
      invalidity of the Documents to which the Sponsor is a party or the Notes,
      (ii) seeking to prevent the issuance of the Notes or the consummation of
      any of the transactions contemplated by the Documents or (iii) which would
      materially and adversely affect the performance by the Sponsor of
      obligations under, or the validity or enforceability of, the Notes or the
      Documents to which the Sponsor is a party.

            7. To the best knowledge of such counsel, the Commission has not
      issued any stop order suspending the effectiveness of the Registration
      Statement or any order directed to any prospectus relating to the Notes
      (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 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. The Indenture, when executed and delivered, will have been duly
      qualified under the Trust Indenture Act.

            10. The statements in the Prospectus and Prospectus Supplement set
      forth under the captions "ERISA Considerations," "Material Federal Income
      Tax Consequences," and the statements in the Prospectus set forth under
      the caption "Legal Aspects of the Mortgage Loans," 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.

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


                                       11
   12
            12. Such other matters as the Underwriters 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 Sponsor
      and the Originators, the Indenture 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 Sponsor and the Originators.

            E. The Underwriters 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 Underwriters and
      counsel for the Underwriters, to the effect that they have performed
      certain specified procedures requested by the Underwriters with respect to
      the information set forth in the Prospectus and certain matters relating
      to the Master Servicer.

            F. The Notes shall have been rated in the highest rating category by
      Standard & Poor's Ratings Services and by Moody's Investors Service, Inc.,
      and such ratings shall not have been rescinded or downgraded. The
      Underwriters 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 Notes. 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 Underwriters shall have received from the Sponsor a
      certificate, signed by the president, a senior vice president or a vice
      president of the Sponsor, dated the Closing Date, to the effect that the
      signer of such certificate has carefully examined the Registration
      Statement, the Sale and Servicing Agreement, and this Agreement and that,
      to the best of his or her knowledge based upon reasonable investigation:

            1. the representations and warranties of the Sponsor in this
      Agreement, as of the Closing Date, and in the Sale and Servicing
      Agreement, the Insurance Agreement, and in all related agreements, as of
      the date specified in such agreements, are true and correct, and the
      Sponsor 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. except as set forth in the Prospectus, there are no actions,
      suits or proceedings pending, or to the best of such officer's knowledge,
      threatened against or affecting the Sponsor which if adversely determined,
      individually or in the aggregate, would be reasonably likely to adversely
      affect the Sponsor's obligations under the Documents to which it is a
      party in any material way; and no merger, liquidation, dissolution or
      bankruptcy of the Sponsor is pending or contemplated;


                                       12
   13
            3. the information contained in the Registration Statement and the
      Prospectus relating to the Sponsor, 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 Sale 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 by-laws of the Sponsor since June 30, 1999,
      and no such amendment has been authorized. No event has occurred since
      June 30, 1999, which has affected the good standing of the Sponsor under
      the laws of the State of Delaware;

            6. there has not occurred any material adverse change, or, except as
      set forth in the Prospectus, any development involving a prospective
      material adverse change, in the condition, financial or otherwise, or in
      the earnings, business or operations of the Sponsor and its subsidiaries,
      taken as a whole, from June 30, 1999;

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

            8. each person who, as an officer or representative of the Sponsor,
      signed or signs the Registration Statement, the Documents 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 Documents 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 Sponsor shall attach to such certificate a true and correct copy
      of its certificate or articles of incorporation, as appropriate, and
      by-laws 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.


                                       13
   14
            H. The Underwriters shall have received a favorable opinion of
      counsel to the Indenture Trustee, dated the Closing Date and in form and
      substance satisfactory to the Underwriters, to the effect that:

            1. the Indenture 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 Documents to which it is a party to;

            2. the Documents to which the Indenture Trustee is a party have been
      duly authorized, executed and delivered by the Indenture Trustee and such
      Documents constitute the legal, valid and binding obligation of the
      Indenture Trustee, enforceable against the Indenture 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 Indenture 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 Indenture Trustee in connection with its execution and delivery of the
      Documents to which it is a party or the performance of its obligations
      thereunder;

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

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

            I. The Underwriters shall have received from the Indenture Trustee a
      certificate, signed by the President, a senior vice president or a vice
      president of the Indenture Trustee, dated the Closing Date, to the effect
      that each person who, as an officer or representative of the Indenture
      Trustee, signed or signs the Notes, the Sale and Servicing Agreement, the
      Indenture or any other document delivered


                                       14
   15
      pursuant hereto, on the date hereof or on the Closing Date, in connection
      with the transactions described in the Sale and Servicing Agreement and
      the Indenture 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 Notes 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 Underwriters shall have received a favorable opinion of
      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 an insurance corporation, duly incorporated and
      validly existing under the laws of its state of incorporation. 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, the
      Insurance Agreement and the Indemnification Agreement are within the
      corporate power of the Insurer and have been authorized by all necessary
      corporate action on the part of the Insurer; the Policy has been duly
      executed and is the valid and binding obligation of the Insurer
      enforceable in accordance with its terms except that the enforcement of
      the Policy may be limited by laws relating to bankruptcy, insolvency,
      reorganization, moratorium, receivership and other similar laws affecting
      creditors' rights generally and by general principles of equity
      (regardless of whether the enforcement of such remedies is considered in a
      proceeding in equity or at law).

            3. The Insurer is authorized to deliver the Indemnification
      Agreement and the Insurance Agreement and such agreements have been duly
      executed and delivered and constitute the legal, valid and binding
      obligations of the Insurer enforceable in accordance with its terms except
      that the enforcement of the Insurance 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, in the case of the
      Indemnification Agreement, subject to principles of public policy limiting
      the right to enforce the indemnification provisions contained therein
      insofar as such provisions relate to indemnification for liabilities
      arising under securities laws.

            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,


                                       15
   16
      and approved by, all governmental authorities having jurisdiction over the
      Insurer in connection with the Policy.

            5. The execution and delivery of the Insurance Agreement, the
      Indemnification Agreement and the Policy, and the compliance with the
      terms and provisions thereof, will not conflict with, result in a breach
      of or constitute a default under any of the terms, provisions or
      conditions of the Restated Charter or By-Laws of the Insurer. The
      execution, delivery and performance by the Insurer of its obligations
      under the policy do not, to the extent that either of the following would
      effect the validity or enforceability of the Policy, (a) contravene any
      law or government regulation or order presently binding on the Insurer or
      (b) contravene any provision of or constitute a default under any
      indenture, contract or other instrument to which the Insurer is a party or
      by which the Insurer is bound.

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

            7. The information set forth under the caption "The Insurer and the
      Policy" in the Prospectus Supplement, 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 Sponsor, the
      Indenture 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. Since June 30, 1999, 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 Sponsor or in any rating
      accorded any securities of the Sponsor, if any, by any "nationally
      recognized statistical rating organization," as such term is defined for
      purposes of the Act.

            M. On or prior to the Closing Date, there shall not have occurred
      any downgrading, nor shall any notice have been given of (A) any intended
      or potential downgrading or (B) any review or possible change in rating
      the direction of which has not been indicated, in the rating accorded the
      Insurer's claims paying ability by any "nationally recognized statistical
      rating organization," as such term is defined for purposes of the 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 June 30, 1999, of (A) the Sponsor
      and any subsidiaries or (B) the Insurer, that is in the Underwriters'
      judgment material and adverse and that makes it in the Underwriters'
      judgment impracticable to market the Notes on the terms and in the manner
      contemplated in the Prospectus.


                                       16
   17
            O. The Underwriters 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
      Insurance Agreement, 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, proceedings or investigations
      pending or, to the best of Insurer's knowledge, threatened against it at
      law or in equity before or by any court, governmental agency, board or
      commission or any arbitrator which, if adversely determined, individually
      or in the aggregate, would materially and adversely affect the Insurer's
      condition (financial or otherwise) or operations or which would materially
      and adversely effect its ability to perform its obligations under the
      Policy, the Insurance Agreement or the Indemnification Agreement;

            2. The information contained in the Prospectus Supplement under the
      caption "The Insurer and the Policy" (the "Insurer Information") is
      limited and does not purport to provide the scope of disclosure required
      to be included in a prospectus for a registrant under the Act, in
      connection with the public offer and sale of securities of such
      registrant. Within such limited scope of disclosure, the Insurer
      Information does not contain any untrue statement of a material fact or
      omits to state a material fact necessary to make the statements therein,
      in light of the circumstances under which they were made, not misleading;

            3. The tables regarding the Insurer's capitalization set forth under
      the heading "The Insurer and the Policy" in the Prospectus Supplement
      presents accurately and fairly the capitalization of the Insurer as of
      June 30, 1999;

            4. The consolidated financial statements of the Insurer as of
      December 31, 1998 and December 31, 1997, and for each of the years in the
      three-year period ended December 31, 1998, 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 consolidated financial statements of the Insurer as of June 30,
      1999 and for the periods ending June 30, 1999 and June 30, 1998 included
      in the Quarterly Report on Form 10-Q of Ambac Financial Group Inc. for the
      period ended June 30, 1999, 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, 1998 audited statements;

   18
            5. No material adverse change in such the financial condition of the
      Insurer which would materially and adversely affect its ability to perform
      its obligations under the Policy.

            6. The execution and delivery of the Insurance Agreement, the
      Indemnification Agreement and the Policy and the compliance with the terms
      and provisions thereof will not conflict with, result in a breach of, or
      constitute a default under any of the terms, provisions or conditions of,
      the Restated Charter of By-Laws of the Insurer, or any agreement,
      indenture or other instrument to which the Insurer is a party.

            7. The issuance of the Policy and the execution, delivery and
      performance of the Indemnification Agreement and the Insurance Agreement
      have been duly authorized by all necessary corporate proceedings. No
      further approvals or filings of any kind, including, without limitation,
      any further approvals of or further filing with any governmental agency or
      other governmental authority, or any approval of the Insurer's board of
      directors or stockholders, are necessary for the Policy, the
      Indemnification Agreement and the Insurance Agreement to constitute the
      legal, valid and binding obligations of the Insurer.

            8. To the best knowledge of such officer, since June 30, 1999, no
      material adverse change has occurred in the financial position of the
      Insurer other than as may be set forth in the Prospectus Supplement.

            The officer of the Insurer certifying to items 5-8 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
      by-laws, all of which are in full force and effect on the date of such
      certificate.

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

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

            R. The Underwriters shall have received from Dewey Ballantine LLP,
      special counsel to the Sponsor, such opinion or opinions, dated the
      Closing Date, with respect to certain tax matters.


                                       18
   19
            S. The Underwriters and counsel for the Underwriters shall have
      received copies of any opinions of counsel to the Sponsor or the Insurer
      supplied to the Indenture Trustee relating to matters with respect to the
      Notes or the Policy. Any such opinions shall be dated the Closing Date and
      addressed to the Underwriters or accompanied by reliance letters to the
      Underwriters or shall state the Underwriters may rely thereon.

            T. The Underwriters shall have received such further information,
      certificates and documents as the Underwriters may reasonably have
      requested not later than the business day prior to the Closing Date.

            U. There shall have been executed and delivered by Advanta Mortgage
      Holding Company, the indirect corporate parent of the Sponsor and direct
      corporate parent of the Master Servicer ("AMHC"), a letter agreement with
      the Trust and the Insurer substantially in the form of Exhibit A hereto.

            V. There shall have been executed and delivered by AMHC a letter
      agreement with the Underwriters and the Insurer substantially in the form
      of Exhibit B hereto.

            W. 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 Notes 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 Originators
      in connection with the issuance and sale of the Notes as herein
      contemplated shall be satisfactory in form and substance to the
      Underwriters and counsel for the Underwriters.

            X. 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; (i) a banking moratorium shall
      have been declared by Federal or state authorities; (ii) 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
      (iii) 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 Underwriters,
      impractical or inadvisable to proceed with the public offering or delivery
      of the Notes on the terms and in the manner contemplated in the
      Prospectus.


                                       19
   20
      If any condition specified in this Section 6 shall not have been fulfilled
when and as required to be fulfilled, this Agreement may be terminated by the
Underwriters by notice to the Sponsor 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 7.

      All opinions, letters, evidence and Notes 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 7. Payment of Expenses  The Sponsor agrees to pay: (a) the
costs incident to the authorization, issuance, sale and delivery of the Notes
and any taxes payable in connection therewith; (b) the costs incident to the
preparation, printing and filing under the Act of the Registration Statement and
any amendments and exhibits thereto; (c) the costs of distributing the
Registration Statement as originally filed and each amendment thereto and any
post-effective amendments thereof (including, in each case, exhibits), the
Prospectus and any amendment or supplement to the Prospectus or any document
incorporated by reference therein, all as provided in this Agreement; (d) the
costs of reproducing and distributing this Agreement; (e) the fees and expenses
of qualifying the Notes under the securities laws of the several jurisdictions
as provided in Section 5(F) hereof and of preparing, printing and distributing
any Blue Sky Memorandum or Legal Investment Survey (including related fees and
expenses of counsel to the Underwriters); (f) any fees charged by securities
rating services for rating the Notes; (g) any amounts in excess of $50,000 of
the total of the costs and expenses of Brown & Wood LLP; and (h) all other costs
and expenses incident to the performance of the obligations of the Sponsor;
provided, however, that, except as provided in this Section 7, the Underwriters
shall pay its own costs and expenses, including an amount not to exceed $50,000
of the total of the costs and expenses of Brown & Wood LLP, any transfer taxes
on the Notes which they may sell and the expenses of marketing any offering of
the Notes made by the Underwriters (including expenses incident to the
preparation, printing and distribution of Computational Materials and other
Derived Information).

      If this Agreement is terminated by the Underwriters, in accordance with
the provisions of Section 6 or Section 10, the Sponsor shall reimburse the
Underwriters for their respective reasonable out-of-pocket expenses, including
fees and disbursements of Brown & Wood LLP.

            SECTION 8. Indemnification and Contribution

            A. The Sponsor agrees to indemnify and hold harmless each
      Underwriter and each person, if any, who controls the respective
      Underwriter within the meaning of Section 15 of the Act from and against
      any and all loss, claim, damage or liability, severally but not jointly,
      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
      Notes), to which each such Underwriter or any such controlling person may
      become subject, under the Act or otherwise, insofar as such loss, claim,
      damage, liability or action arises out of, or is based upon, (i) any


                                       20
   21
      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 each 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 Sponsor 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 the Prospectus or the
      Registration Statement in reliance upon and in conformity with written
      information (including any Derived Information) furnished to the Sponsor
      by the Underwriters specifically for inclusion therein. For purposes of
      the last proviso to the immediately preceding sentence, the term
      "Prospectus" shall not be deemed to include the documents incorporated
      therein by reference, and the Underwriters shall not 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 the Underwriters
      have 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 Sponsor may otherwise have to any Underwriter
      or any controlling person of any Underwriter.

            B. Each Underwriter severally but not jointly will indemnify and
      hold harmless the Sponsor, its directors, its officers who signed the
      Registration Statement, and each person, if any, who controls the Sponsor
      within the meaning of Section 15 of the Act against any and all loss,
      claim, damage or liability, or any action in respect thereof, to which the
      Sponsor or any such director, officer or controlling person may become
      subject, under the Act or otherwise, insofar as such loss, claim, damage,
      liability or action arises out of, or is based upon, (i) any untrue
      statement or alleged untrue statement of a material fact contained in the
      Registration Statement, (ii) the omission or alleged omission to state
      therein a material fact required to be stated therein or necessary to make
      the statements therein not misleading, (iii) any untrue statement or
      alleged untrue statement of a material fact contained in the Prospectus or
      (iv) the omission or alleged omission to state therein a material fact
      required to be stated therein or necessary to make the statements therein,
      in the light of the circumstances under which they were made, not
      misleading, but in each case only to the extent that the untrue statement
      or alleged untrue statement or omission or alleged omission was made in
      reliance upon and in conformity with written information (excluding any
      Derived Information which is covered in paragraph (E) below) furnished to
      the Sponsor by or on behalf of the Underwriters specifically for inclusion
      therein, and shall


                                       21
   22
      reimburse the Sponsor, and any such director, officer or controlling
      person for any legal or other expenses reasonably incurred by the Sponsor
      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 the
      Underwriters may otherwise have to the Sponsor or any such director,
      officer or controlling person.

            C. Promptly after receipt by any indemnified party under this
      Section 8 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 8, 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 8 except to the extent it has been materially prejudiced by such
      failure; and provided further, however, 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 8.

            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 8 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


                                       22
   23
      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 such Underwriter, if
      the indemnified parties under this Section 8 consist of such Underwriter
      or any of its controlling persons, or by the Sponsor if the indemnified
      parties under this Section 8 consist of the Sponsor or any of the
      Sponsor's directors, officers or controlling persons.

            Each indemnified party, as a condition of the indemnity agreements
      contained in Section 8(A) and (B), shall use its best efforts to cooperate
      with the indemnifying party in the defense of any such action or claim. No
      indemnifying party shall be liable for any settlement of any such action
      effected without its written consent (which consent shall not be
      unreasonably withheld), but if settled with its written consent or if
      there be a final judgment for the plaintiff in any such action, the
      indemnifying party agrees to indemnify and hold harmless any indemnified
      party from and against any loss or liability by reason of such settlement
      or judgment.

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

            D. Each Underwriter agrees to deliver to the Sponsor a copy of its
      Derived Information no later than one (1) business day prior to the date
      such information is required to be filed, pursuant to the No-Action
      Letters (as defined herein), with the Commission on Form 8-K.

            E. Each Underwriter agrees, assuming all Sponsor-Provided
      Information (defined below) is accurate and complete in all material
      respects, to severally and not jointly indemnify and hold harmless the
      Sponsor, each of the Sponsor's officers and directors and each person who
      controls the Sponsor within the meaning of Section 15 of the Act against
      any and all losses, claims, damages or liabilities, joint or several, to
      which they may become subject under the Act or otherwise, insofar as such
      losses, claims, damages or liabilities (or actions in respect thereof)
      arise out of or are based upon any untrue statement 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 and when read in conjunction with the Prospectus, 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


                                       23
   24
      incurred. The obligations of the Underwriters under this Section 8(E)
      shall be in addition to any liability which the respective Underwriters
      may otherwise have.

            The procedures set forth in Section 8(C) shall be equally applicable
      to this Section 8(E).

            F. For purposes of this Section 8, the term "Derived Information"
      means such portion, if any, of the information delivered to the Sponsor
      pursuant to Section 8(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 Sponsor-Provided Information; and

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

      "Sponsor-Provided Information" means any computer tape furnished to the
      Underwriters by the Sponsor 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 LLP 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 8 shall for
      any reason be unavailable to or insufficient to hold harmless an
      indemnified party under Section 8(A) or (B) in respect of any loss, claim,
      damage or liability, or any action in respect thereof, referred to
      therein, then (i) 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, in such proportion as shall be appropriate to
      reflect the relative benefits received by the Sponsor on the one hand and
      the Underwriters on the other from the offering of the Notes 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 8(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 Sponsor on the one hand and the


                                       24
   25
      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 Sponsor on the one hand and the
      Underwriters on the other shall be deemed to be in such proportion as the
      total net proceeds from the offering (before deducting expenses) received
      by the Sponsor to the total underwriting discounts and commissions.

            The relative fault of the Underwriters and the Sponsor 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 Sponsor or by the
      Underwriters, the intent of the parties and their relative knowledge,
      access to information and opportunity to correct or prevent such statement
      or omission and other equitable considerations.

            The Sponsor and the Underwriters agree that it would not be just and
      equitable if contributions pursuant to this Section 8(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 8(G) shall be deemed to include, for
      purposes of this Section 8(G), any legal or other expenses reasonably
      incurred by such indemnified party in connection with investigating or
      defending any such action or claim.

            For purposes of this Section 8, in no case shall each Underwriter be
      responsible for any amount in excess of (x) the amount received by such
      Underwriter in connection with its resale of the Notes over (y) the amount
      paid by such Underwriter to the Sponsor for the Notes 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 confirm that the information set forth in the
      third, fourth, fifth, sixth, seventh and ninth paragraphs 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 Sponsor by or on behalf of the Underwriters
      specifically for inclusion in the Registration Statement and the
      Prospectus.

            SECTION 9. Representations, Warranties and Agreements to Survive
Delivery  All representations, warranties and agreements contained in this
Agreement or contained in certificates of officers of the Sponsor submitted
pursuant hereto shall remain operative and in full force and effect, regardless
of any investigation made by or on behalf of such Underwriter or controlling
persons thereof, or by or on behalf of the Sponsor and shall survive delivery of
any Notes to the Underwriters.


                                       25
   26
            SECTION 10. Termination of Agreement  The Underwriters may terminate
this Agreement immediately upon notice to the Sponsor at any time at or prior to
the Closing Date if any of the events or conditions described in Section 6(X) of
this Agreement shall occur and be continuing. In the event of any such
termination, the covenant set forth in the provisions of Section 7, the
indemnity agreement set forth in Section 8, and the provisions of Sections 9 and
13 shall remain in effect.

            SECTION 11. Notices  All statements, requests, notices and
