Group II Floating Rate Certificates (the "Class A-2 Certificates" together with
the Class A-1 Certificates, the "Offered Certificates") and (iii) the residual

Only the Class A-1 Certificates are offered by the Underwriters.

                  The Offered Certificates will be issued by the Advanta
Mortgage Loan Trust 1998-3 (the "Trust"), and will evidence in the aggregate the
beneficial interest in a sub-trust of a trust estate (the "Trust Estate")
consisting primarily of a pool (the "Group I Mortgage Pool") of closed-end
mortgage loans having variable rates of interest (the "Group I Mortgage Loans"),
amounts on deposit with Bankers Trust Company of California, N.A., as trustee of
the Trust (the "Trustee") in an account to be used to acquire additional
mortgage loans following the Closing Date (as hereinafter defined) for the Trust
(the "Pre-Funding Account") and certain related property. The Mortgage Loans
shall have, as of September 23, 1998 (the "Closing Date"), an aggregate
principal balance of approximately $400,000,000 and the Pre-Funding Account
shall have approximately $108,562,000. The Offered Certificates are to be issued
under a pooling and servicing agreement, to be dated as of September 1, 1998
(the "Pooling and Servicing Agreement"), among the Company, as sponsor, Advanta
Mortgage Corp. USA, as master servicer, and the Trustee.

                  On or prior to the date of issuance of the Certificates, the
Company will obtain a guaranty insurance policy (the "Policy") issued by MBIA
Insurance Corporation (the "Insurer") which will unconditionally and irrevocably
guarantee to the Trustee for the benefit of the holders of Class A-1
Certificates the amount by which the Group I
   2
Insured Distribution Amount (as defined in the Pooling and Servicing Agreement)
for the Class A-1 Certificates exceeds the Group I Total Available Funds (as
defined in the Pooling and Servicing Agreement) amount for each such group.

                  The Offered Certificates are more fully described in a
Registration Statement which the Company has furnished to the Underwriters.
Capitalized terms used but not defined herein shall have the meanings given to
them in the Pooling and Servicing Agreement.

                  Simultaneously with the execution of the Pooling and Servicing
Agreement, the Company will enter into a conveyance agreement pursuant to the
Master Loan Transfer Agreement dated as of September 23, 1998 among the Trustee,
Advanta Mortgage Conduit Services, Inc. and the Affiliated Originators named
thereon (together, the "Purchase Agreement"), pursuant to which the Affiliated
Originators will transfer to the Company all of their right, title and interest
in and to the Mortgage Loans as of the Closing Date.

                  The Company will also enter into an Indemnification Agreement
(the "Indemnification Agreement") dated as of September 10, 1998 among the
Underwriters, the Company and the Insurer, governing the liability of the
several parties with respect to the losses resulting from material misstatements
or omissions contained in the Prospectus Supplement.

                  of incorporation or bylaws of the Company; (ii) any term or
                  provision of any material agreement, contract, instrument or
                  indenture, to which the Company is a party or is bound and
                  known to such counsel; or (iii) any order, judgment, writ,
                  injunction or decree of any court or governmental agency or
                  body or other tribunal having jurisdiction over the Company
                  and known to such counsel; or (B) results in, or will result
                  in the creation or imposition of any lien, charge or
                  encumbrance upon the Trust Estate or upon the Class A-1
                  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

                                       12
   13
                  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 Insurance Agreement, the
                  Indemnification Agreement, the Purchase Agreement or the
                  offer, issuance, sale or delivery of the Class A-1
                  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 Insurance Agreement, the
                  Indemnification Agreement, this Agreement, the Purchase
                  Agreement or the Class A-1 Certificates, (ii) seeking to
                  prevent the issuance of the Class A-1 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 Insurance Agreement, the
                  Indemnification Agreement, the Class A-1 Certificates, the
                  Purchase Agreement or this Agreement or (iv) that would
                  adversely affect the status of the Trust Estate as a "real
                  estate mortgage investment conduit" ("REMIC") as such term is
                  defined in the Internal Revenue Code of 1986, as amended.

                       7. To the best of the knowledge of such counsel, the
                  Commission has not issued any stop order suspending the
                  effectiveness of the Registration Statement or any order
                  directed to any prospectus relating to the Class A-1
                  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

                                       13
   14
                  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 Pooling and
                  Servicing 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 Class A-1 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 Class A-1
                  Certificates issued pursuant to the Pooling and Servicing
                  Agreement will be treated as the "regular interests" in the
                  REMIC and the Class R Certificates issued pursuant to the
                  Pooling and Servicing Agreement will be treated as the sole
                  "residual interest" in the REMIC. The Trust will not be
                  subject to tax upon its income or assets by any taxing
                  authority of the State of New York or New York City or of the
                  State of California (except that no opinion need be expressed
                  with respect to any minimum tax).

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

                       14. No information has come to such counsel's attention
                  which causes them to believe that the Prospectus (other than
                  the financial statement and other financial and statistical
                  data contained therein, as to which such counsel need express
                  no opinion), as of the date thereof,

                                       14
   15
                  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 Class A-1 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 Class A-1
                  Certificates. Any such opinions shall be dated the Closing
                  Date and addressed to the Underwriters or accompanied by
                  reliance letters to the Underwriters or shall state that the
                  Underwriters may rely upon them.

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

                       1. the representations and warranties of the Company in
                  this Agreement, as of the Closing Date, and in the Pooling and
                  Servicing Agreement, the Insurance 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;

                                       15
   16
                       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 Insurance Agreement, the
                  Indemnification Agreement, this Agreement or the Purchase
                  Agreement in any material way; and no merger, liquidation,
                  dissolution or bankruptcy of the Company is pending or
                  contemplated;

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

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

                       5. there has been no amendment or other document filed
                  affecting the articles of incorporation or bylaws of the
                  Company since June 30, 1998, and no such amendment has been
                  authorized. No event has occurred since June 30, 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 June 30, 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 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 Insurance 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 Insurance Agreement, the
                  Indemnification

                                       16
   17
                  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;

                       4. the Class A-1 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
                  Class A-1 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 Class A-1 Certificates
                  shall have been duly executed and issued at or prior to the
                  Closing Date and shall conform in all material respects to the
                  description thereof in the Prospectus.

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

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

                       2. The execution and delivery by the Insurer of the
                  Policy, 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.

                       3. The Insurer is authorized to deliver the
                  Indemnification Agreement, the Insurance Agreement and such
                  agreement has been duly executed and delivered and constitute
                  the legal, valid and binding obligations of the Insurer
                  enforceable in accordance with its terms except that the
                  enforcement of the Insurance Agreement and the Indemnification

                                       18
   19
                  Agreement may be limited by laws relating to bankruptcy,
                  insolvency, reorganization, moratorium, receivership and other
                  similar laws affecting creditors' rights generally and by
                  general principles of equity and by public policy
                  considerations relating to indemnification for securities law
                  violations.

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

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

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

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

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

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

                       N. There has not occurred any change, or any development
                  involving a prospective change, in the condition, financial or
                  otherwise, or

                                       19
   20
                  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 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 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,
                  the Insurance Agreement, or the Indemnification Agreement;

                       2. Each person who as an officer or representative of the
                  Insurer, signed or signs the Policy, the Insurance Agreement,
                  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 INSURER" present
                  fairly the capitalization of the Insurer as of June 30, 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
                  1933 Act;

                                       20
   21
                       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 June 30, 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 June 30,
                  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,
                  indicating the requirements of applicable local law which must
                  be complied with in order to transfer and service the Mortgage
                  Loans pursuant to the Pooling and Servicing Agreement and the
                  Company shall have complied with all such requirements.

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

                       R. The Representative and counsel for the Underwriters
                  shall have received copies of any opinions of counsel to the
                  Company supplied to the Trustee relating to matters with
                  respect to the Certificates. Any such opinions shall be dated
                  the Closing Date and addressed to the

                                       21
   22
                  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 Class A-1 Certificates as herein
                  contemplated shall be satisfactory in form and substance to
                  the Representative and counsel for the Underwriters.

                       W. Subsequent to the execution and delivery of this
                  Agreement none of the following shall have occurred: (i)
                  trading in securities generally on the New York Stock
                  Exchange, the American Stock Exchange or the over-the-counter
                  market shall have been suspended or minimum prices shall have
                  been established on either of such exchanges or such market by
                  the Commission, by such exchange or by any other regulatory
                  body or governmental authority having jurisdiction; (ii) a
                  banking moratorium shall have been declared by Federal or
                  state authorities; (iii) the United States shall have become

                  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



                                       22
   23

         If any condition specified in this Section VI shall not have been

by the Representative by notice to the Company at any time at or prior to the
Closing Date, and such termination shall be without liability of any party to
any other party except as provided in Section VII.

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

         Section VII. Payment of Expenses. The Company agrees to pay: (a) the

A-1 Certificates and any taxes payable in connection therewith; (b) the costs

distributing the Registration Statement as originally filed and each amendment
thereto and any post-effective amendments thereof (including, in each case,

all as provided in this Agreement; (d) the costs of reproducing and distributing
this Agreement; (e) the fees and expenses of qualifying the Class A-1

         Section VIII. Indemnification and Contribution.

                  A. The Company agrees to indemnify and hold harmless each
         Underwriter and each person, if any, who controls such Underwriter


                                       23
   24
         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 Class A-1 Certificates), to which such Underwriter or any such
         controlling person may become subject, under the Securities Act or
         otherwise, insofar as such loss, claim, damage, liability or action
         arises out of, or is based upon, (i) any untrue statement or alleged
         untrue statement of a material fact contained in the Registration
         Statement, (ii) the omission or alleged omission to state therein a
         material fact required to be stated therein or necessary to make the
         statements therein not misleading, (iii) any untrue statement or
         alleged untrue statement of a material fact contained in the Prospectus
         or (iv) the omission or alleged omission to state therein a material
         fact required to be stated therein or necessary to make the statements
         therein, in the light of the circumstances under which they were made,
         not misleading and shall reimburse such Underwriter and each such
         controlling person promptly upon demand for any legal or other expenses
         reasonably incurred by such Underwriter or such controlling person in
         connection with investigating or defending or preparing to defend
         against any such loss, claim, damage, liability or action as such
         expenses are incurred; provided, however, that the Company shall not be
         liable in any such case to the extent that any such loss, claim,
         damage, liability or action arises out of, or is based upon, any untrue
         statement or alleged untrue statement or omission or alleged omission
         made in any Preliminary Prospectus, the Prospectus or the Registration
         Statement in reliance upon and in conformity with written information
         (including any Derived Information) furnished to the Company through
         the Representative specifically for inclusion therein; 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 Class A-1 Certificates to any person by such
         Underwriter if such Underwriter failed to send or give a copy of the
         Prospectus, as amended or supplemented, to that person within the time
         required by the Securities Act, and the untrue statement or alleged
         untrue statement of a material fact or the omission or alleged omission
         to state a material fact in the Preliminary Prospectus was corrected in
         the Prospectus, unless such failure resulted from non-compliance by the
         Company with Section V(C). For purposes of the last proviso to the
         immediately preceding sentence, the term "Prospectus" shall not be
         deemed to include the documents incorporated therein by reference, and
         none of the Underwriters shall be obligated to send or give any
         supplement or amendment to any document incorporated therein by
         reference to any person other than a person to whom such Underwriter
         had delivered such incorporated document or documents in response to a
         written request therefor. The foregoing indemnity agreement is in


                                       24
   25
         addition to any liability which the Company may otherwise have to any
         Underwriters or any controlling person of such Underwriter.

                  B. Each Underwriter agrees severally, and not jointly to
         indemnify and hold harmless the Company, each of its directors, each of
         its officers who signed the Registration Statement, and each person, if
         any, who controls the Company within the meaning of Section 15 of the
         Securities Act against any and all loss, claim, damage or liability, or
         any action in respect thereof, to which the Company or any such
         director, officer or controlling person may become subject, under the
         Securities Act or otherwise, insofar as such loss, claim, damage,
         liability or action arises out of, or is based upon, (i) any untrue
         statement or alleged untrue statement of a material fact contained in
         the Registration Statement, (ii) the omission or alleged omission to
         state therein a material fact required to be stated therein or
         necessary to make the statements therein not misleading, (iii) any
         untrue statement or alleged untrue statement of a material fact
         contained in the Prospectus or (iv) the omission or alleged omission to
         state therein a material fact required to be stated therein or
         necessary to make the statements therein, in the light of the
         circumstances under which they were made, not misleading, but in each
         case only to the extent that the untrue statement or alleged untrue
         statement or omission or alleged omission was made in reliance upon and
         in conformity with written information furnished to the Company by or
         on behalf of such Underwriter specifically for inclusion therein, and
         shall reimburse the Company and any such director, officer or
         controlling person for any legal or other expenses reasonably incurred
         by the Company or any director, officer or controlling person in
         connection with investigating or defending or preparing to defend
         against any such loss, claim, damage, liability or action as such
         expenses are incurred. The foregoing indemnity agreement is in addition
         to any liability which any Underwriter may otherwise have to the
         Company or any such director, officer or controlling person. 

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

         If any such claim or action shall be brought against an indemnified
party, and it shall notify the indemnifying party thereof, the indemnifying
party shall be entitled to participate therein and, to the extent that it
wishes, jointly with any other similarly 


                                       25
   26
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.

         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.


                                       26
   27
                  D. Each Underwriter agrees to deliver to the Company no later
         than the date on which the Prospectus Supplement is required to be
         filed pursuant to Rule 424 with a copy of its Derived Information
         (defined below) for filing with the Commission on Form 8-K.

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

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

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

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

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

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

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

         The terms "Collateral term sheet" and "Structural term sheet" shall
have the respective meanings assigned to them in the February 13, 1995 letter
(the "PSA 


                                       27
   28
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 Class A-1 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 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 


                                       28
   29
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 Class A-1 Certificates
purchased by such Underwriter hereunder. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.

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

         Section IX. Representations, Warranties and Agreements to Survive
Delivery. All representations, warranties and agreements contained in this
Agreement or contained in certificates of officers of the Company submitted
pursuant hereto shall remain operative and in full force and effect, regardless
of any investigation made by or on behalf of the Underwriters or controlling
persons thereof, or by or on behalf of the Company and shall survive delivery of
any Class A-1 Certificates to the Underwriters.

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

         Section XI. Notices. All statements, requests, notices and agreements
hereunder shall be in writing, and:

         Section XII. Persons Entitled to the Benefit of this Agreement. This
Agreement shall inure to the benefit of and be binding upon the Underwriters and

                                       29
   30
hereof are for the sole benefit of only those persons, except that the
representations, warranties, indemnities and agreements contained in this
Agreement shall also be deemed to be for the benefit of the person or persons,
if any, who control the Underwriters within the meaning of Section 15 of the
Securities Act, and for the benefit of directors of the Company, officers of the
Company who have signed the Registration Statement and any person controlling
the Company within the meaning of Section 15 of the Securities Act. Nothing in
this Agreement is intended or shall be construed to give any person, other than
the persons referred to in this Section XII, any legal or equitable right,
remedy or claim under or in respect of this Agreement or any provision contained
herein.

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

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

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

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

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

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

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

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