Agreement" and together with the Insurance Agreement, the "Insurance
Agreements") by and among Onyx, the Company, the Representative and the Insurer,
the Insurer will issue its financial guarantee insurance policy (the
"Guarantee") to the Indenture Trustee for the benefit of the Securityholders
guaranteeing timely payment of interest and ultimate payment of principal at
maturity on the Securities.

         As of the Closing Date, the Trust's assets (the "Trust Property") will
include: (i) a pool of fixed rate motor vehicle retail installment sales
contracts and installment loan agreements (the "Contract Pool"), all of which
were purchased from the Seller pursuant to the Purchase Agreement and secured by
new and used automobiles, light-duty trucks and vans (the "Financed Vehicles"),
(ii) certain documents relating to the Funded Contracts, (iii) with respect to
contracts (the "Initial Contracts") originated prior to October 1, 1999 (the
"Initial Cut-Off Date") certain monies received with respect to the Initial
Contracts on or after the Initial Cut-off Date, (iv) with respect to contracts
(the "Subsequent Contracts" and together with the Initial Contracts, the "Funded
Contracts"), originated or purchased after the Initial Cut-Off Date and on or
before October 27, 1999 (the "Subsequent Cut-Off Date"), certain monies received
with respect to the Subsequent Contracts on or after the Subsequent Cut-Off
Date, (v) security interests in the Financed Vehicles and the rights to receive
proceeds from claims on certain insurance policies covering the Financed
Vehicles or the individual obligors under each related Funded Contract, (vi) all
amounts on deposit in the Collection Account, the Payment Account, the Note

Capitalized Interest Account, which may be paid to the Seller under certain
circumstances), (vii) the right of the Company to cause Onyx to repurchase
certain Funded Contracts under certain circumstances, and (viii) all proceeds of

Prefunding Account to purchase contracts (the "Prefunded Contracts" and together
with the Funded Contracts, the "Contracts") originated or purchased after the

Company.

         The Securities will be issued in an aggregate principal amount of

and the amount in the Prefunding Account. The term "Cut-Off Date" as used herein

         The Company hereby agrees with the Underwriters, as follows:

         2. Representations and Warranties of the Company. The Company
represents and warrants to, and agrees with the Underwriters that:

                  (i) The Company meets the requirements for use of Form S-3
         under the Securities Act of 1933 (the "Act"), as amended, and has filed

         including a prospectus and forms of prospectus supplements, for
         registration under the Act of the offering and sale of the Notes and
         Certificates. The Company may have filed one or more amendments
         thereto, each of which amendments has previously been furnished to the
         Representative. The Company will also file with the Commission a
         prospectus supplement in accordance with Rule 424(b) under the Act. The
         Company has included in the Registration Statement, as amended at the
         Effective Date (as hereinafter defined), all information required by
         the Act and the rules thereunder to be included in the Prospectus (as
         hereinafter defined) with respect to the Notes and Certificates and the
         offering thereof. As filed, the registration statement as amended, the
         forms of prospectus supplements, and any prospectuses or prospectus
         supplements filed pursuant to Rule 424(b) under the Act relating to the
         Notes and Certificates shall, except to the extent that the
         Representative shall agree in writing to a modification, be in all
         substantive respects in the form furnished to the Representative prior
         to the Execution Time (as hereinafter defined) or, to the extent not
         completed at the Execution Time, shall contain only such specific
         additional information and other changes as the Company has advised the
         Representative, prior to the Execution Time, will be included or made
         therein.

                  For purposes of this Agreement, "Effective Time" means the
         date and time as of which such registration statement, or the most
         recent post-effective amendment thereto, if any, was declared effective
         by the Commission, and "Effective Date" means the date of the Effective
         Time. "Execution Time" shall mean the date and time that this Agreement
         is executed and delivered by the parties hereto. Such registration
         statement, as amended at the Effective Time, and including the exhibits
         thereto and any material incorporated by reference therein (including
         any ABS Term Sheets (as defined in Section 4(b) of this Agreement)
         filed on Form 8-K), is hereinafter referred to as the "Registration
         Statement," and any prospectus supplement (the "Prospectus Supplement")
         relating to the Notes and Certificates, as filed with the Commission
         pursuant to and in accordance with Rule 424(b) under the Act is,
         together with the prospectus filed as part of the Registration
         Statement (such prospectus, in the form it appears in the Registration
         Statement or in the form most recently revised and filed with the
         Commission pursuant to Rule 424(b) being hereinafter referred to as the
         "Basic Prospectus"), hereinafter referred to as the "Prospectus". "Rule
         424" refers to such rule under the Act. Any reference herein to the
         Registration Statement, the Prospectus or any Prospectus Supplement
         shall be deemed to refer to and include the documents incorporated by
         reference therein pursuant to Item 12 of Form S-3 which were filed by
         the Company as the originator of the Trust under the

         Securities Exchange Act of 1934, as amended (the "Exchange Act") , on
         or before the Effective Date of the Registration Statement or the issue
         date of the Prospectus or any Prospectus Supplement, as the case may be
         (but shall not be deemed to refer to or include any Form T-1 filed with
         respect to the Indenture Trustee); and any reference herein to the
         terms "amend", "amendment" or "supplement" with respect to the
         Registration Statement, the Prospectus or any Prospectus Supplement
         shall be deemed to refer to and include the filing of any document
         under the Exchange Act after the Effective Date of the Registration
         Statement, or the issue date of the Prospectus or any Prospectus
         Supplement, as the case may be, deemed to be incorporated therein by
         reference.

                  (ii) On the Effective Date and on the date of this Agreement,
         the Registration Statement did or will, and, when the Prospectus was
         first filed and on the Closing Date (as defined below), the Prospectus
         and any Prospectus Supplement did or will comply in all material
         respects with the applicable requirements of the Act, the Exchange Act
         and the Trust Indenture Act of 1939, as amended (the "Trust Indenture
         Act"), and the respective rules and regulations of the Commission
         thereunder (the "Rules and Regulations"). On the Effective Date, the
         Registration Statement did not and will not contain any untrue
         statement of a material fact or omit to state any material fact
         required to be stated therein or necessary in order to make the
         statements therein not misleading; and, on the Effective Date, the
         Prospectus, if not filed pursuant to Rule 424(b), did not or will not,
         and on the date of any filing pursuant to Rule 424(b) and on the
         Closing Date, the Prospectus, together with any Prospectus Supplement,
         did not or will not include 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 the Company makes no
         representation or warranty as to the information contained in or
         omitted from the Registration Statement or the Prospectus in reliance
         upon and in conformity with information furnished in writing to the
         Company by any Underwriter through the Representative specifically for
         use in connection with preparation of the Registration Statement or the
         Prospectus.

                  (iii) Since the respective dates as of which information is
         given in the Registration Statement and the Prospectus, (i) there has
         not been any material adverse change, or any development involving a
         prospective material adverse change, in or affecting the general
         affairs, business, management, financial condition, stockholders'
         equity, results of operations, regulatory status or business prospects
         of the Company or Onyx, and (ii) neither the Company nor Onyx has
         entered into any transaction or agreement (whether or not in the
         ordinary course of business) material to it that, in either case, would
         reasonably be expected to materially adversely affect the interests of
         the holders of the Notes or Certificates, other than as set forth or
         contemplated in the Prospectus.

                  (iv) The Company has been duly incorporated and is validly
         existing as a corporation in good standing under the laws of its
         jurisdiction of incorporation, with full power and authority (corporate
         and other) to own its properties and conduct its businesses as
         described in the Prospectus, and is duly qualified to transact business
         as a foreign corporation in good standing under the laws of each
         jurisdiction where the ownership or leasing of its properties or the
         conduct of its business requires such qualification.

                  (v) As of the Closing Date the representations and warranties
         of the Company, as Seller, in the Servicing Agreement and Trust
         Agreement will be true and correct, and each Funded Contract will
         satisfy the representations and warranties set forth in Section 2.02(b)

                  (vi) As of the related Prefunding Closing Date, the
         representations and warranties of the Company, as Seller, in the
         Servicing Agreement and Trust Agreement will be true and correct, and
         each related Prefunded Contract will satisfy the representations and
         warranties set forth in Section 2.02(d) of the Servicing Agreement.

                  (vii) No consent, approval, authorization or order of, or
         filing with, any court or governmental agency or body is required to be
         obtained or made by the Company for the consummation of the
         transactions contemplated by this Agreement, except such as have been
         obtained and made under the Act, such as may be required under state
         securities laws and the filing of any financing statements required to
         perfect the Trust's interest in the Contracts.

                  (viii) The Company is not in violation of its certificate of
         Incorporation or By-Laws or in default in the performance or observance
         of any obligation, agreement, covenant or condition contained in any
         agreement or instrument to which it is a party or by which it or its
         properties are bound which violation or default would have a material
         adverse effect on the transactions contemplated herein or in the
         Indenture, the Trust Agreement, the Servicing Agreement, the Purchase
         Agreement or the Insurance Agreements. The execution, delivery and
         performance by the Company of this Agreement, the Trust Agreement, the
         Servicing Agreement, the Purchase Agreement or the Insurance Agreements
         and the issuance and sale of the Securities and compliance with the
         terms and provisions thereof will not result in a breach or violation
         of any of the terms and provisions of or constitute a default under,
         any statute, rule, regulation or order of any governmental agency or
         body or any court having jurisdiction over the Company or any of its
         properties or any agreement or instrument to which the Company is a
         party or by which the Company is bound or to which any of the
         properties of the Company is subject, or the Certificate of
         Incorporation or By-Laws of the Company and the Company has full
         corporate power and authority to authorize, cause the Trust to issue,
         and sell the Securities as contemplated by this Agreement, to enter
         into this Agreement, the Trust Agreement, the Servicing Agreement, the
         Purchase Agreement and the Insurance Agreements and to consummate the
         transactions contemplated herein and therein.

                  (ix) This Agreement has been duly authorized, executed and
         delivered by the Company.

                  (x) The Company is not in violation of any provision of any
         existing law or regulation or in default in the performance or
         observance of any obligation, agreement, covenant or condition
         contained in any contract, indenture, mortgage, deed of trust, loan
         agreement, note, lease or other instrument to which it is a party or by
         which it is bound or to which any of its property is subject, which
         violations or defaults separately or in the aggregate would have a
         material adverse effect on the Company or the Trust.

         3. Purchase, Sale, Payment and Delivery of Securities. On the basis of
the representations, warranties and agreements herein contained, but subject to

referred to as the "Closing Date". The Securities so to be delivered shall be
represented by one or more global notes or certificates as applicable registered
in the name of Cede & Co., as nominee for The Depository Trust Company, in such

         4. Offering by the Underwriters. It is understood that, after the
Registration Statement becomes effective, the Underwriters propose to offer the
Securities for sale to the public (which may include selected brokers and
dealers) as set forth in the Prospectus.

         (a) The Underwriters may prepare and provide to prospective investors
certain ABS Term Sheets, in connection with its offering of the Securities,
subject to the following conditions:

                  (i) The Underwriters shall have complied with the requirements
         of the no-action letter, dated February 17, 1995, issued by the
         Commission to the Public Securities Association (the "No-Action
         Letter").

                  (ii) For purposes hereof, "ABS Term Sheets" shall have the
         meaning given such term in the No-Action Letter but shall include only
         those ABS Term Sheets that have been prepared or delivered to
         prospective investors by or at the direction of each of the
         Underwriters.

                  (iii) All ABS Term Sheets provided to prospective investors
         that are required to be filed pursuant to the No-Action Letter shall
         bear a legend substantially in the form attached hereto as either
         Exhibit A-1, Exhibit A-2 or Exhibit A-3, as applicable. The Company
         shall have the right to require specific legends or notations to appear
         on any ABS Term Sheets, the right to require changes regarding the use
         of terminology and the right to determine the types of information
         appearing therein. Notwithstanding the foregoing, this subsection (iii)
         will be satisfied if all ABS Term Sheets referred to herein bear a
         legend in a form previously approved in writing by the Company.


                                       6
<PAGE>   7

                  (iv) Each of the Underwriters shall have provided the Company
         with representative forms of all ABS Term Sheets prior to their first
         use, to the extent such forms have not previously been approved in
         writing by the Company for use by each of the Underwriters. The
         Underwriters shall have provided to the Company, for filing as part of
         a current report on Form 8-K as provided in Section 5(xii), copies (in
         such format as required by the Company) of all ABS Term Sheets that are
         required to be filed with the Commission pursuant to the No-Action
         Letter. Each of the Underwriters may provide copies of the foregoing in
         a consolidated or aggregated form including all information required to
         be filed. All ABS Term Sheets described in this subsection (iv) shall
         have been provided to the Company not later than 10:00 a.m. (New York
         City time) not less than one business day before filing thereof is
         required to be made with the Commission pursuant to the No-Action
         Letter. Neither Underwriter shall have provided to any investor or
         prospective investor in the Securities any ABS Term Sheets on or after
         the day on which ABS Term Sheets are required to be provided to the
         Company pursuant to this subsection (iv) (other than copies of ABS Term
         Sheets previously submitted to the company in accordance with this
         subsection (iv) for filing pursuant to Section 5(xii)), unless such ABS
         Term Sheets are preceded or accompanied by the delivery of a Prospectus
         to such investor or prospective investor.

                  (v) All information included in the ABS Term Sheets shall have
         been generated based on substantially the same methodology and
         assumptions that are used to generate the information in the Prospectus
         as set forth therein; provided that the ABS Term Sheets may have
         included information based on alternative methodologies or assumptions
         if specified therein. If any ABS Term Sheets that are required to be
         filed were based on assumptions with respect to the Contract Pool that
         differ from the final Contract Pool information in any material respect
         or on Securities structuring terms that were revised in any material
         respect prior to the printing of the Prospectus, each Underwriter shall
         have prepared revised ABS Term Sheets based on the final Contract Pool
         information and structuring assumptions, shall have circulated such
         revised ABS Term Sheets to all recipients of the preliminary versions
         thereof that indicated orally to either of the Underwriters they would
         purchase all or any portion of the Securities, and shall have included
         such revised ABS Term Sheets (marked, "as revised") in the materials
         delivered to the Company pursuant to subsection (iv) above.

                  (vi) The Company shall not be obligated to file any ABS Term
         Sheets that have been determined to contain any material error or
         omission, provided that, at the request of the Underwriters, the
         Company will file ABS Term Sheets that contain a material error or
         omission if clearly marked "superseded by materials dated _________"
         and accompanied by corrected ABS Term Sheets that are marked,
         "supersedes material previously dated _______, as corrected." If,
         within the period during which the Prospectus relating to the
         Securities is required to be delivered under the Act, any ABS Term
         Sheets are determined, in the reasonable judgment of the Company or
         either of the Underwriters, to contain a material error or omission,
         each Underwriter shall prepare a corrected version of such ABS Term
         Sheets, shall circulate such corrected ABS Term Sheets to all
         recipients of the prior versions thereof that either indicated orally
         to either of the Underwriters they would purchase all or any portion of
         the Securities, or actually purchased all or any portion thereof, and
         shall deliver copies of such corrected ABS Term


                                       7
<PAGE>   8

         Sheets (marked, "as corrected") to the Company for filing with the
         Commission in a subsequent current report on Form 8-K (subject to the
         Company's obtaining an accountant's comfort letter in respect of such
         corrected ABS Term Sheets).

                  (vii) The Underwriters shall be deemed to have represented as
         of the Closing Date, that, except for ABS Term Sheets provided to the
         Company pursuant to subsection (iv) above, the Underwriters did not
         provide any prospective investors with any information in written or
         electronic form in connection with the offering of the Securities that
         is required to be filed with the Commission in accordance with the
         No-Action Letter.

                  (viii) In the event of any delay in the delivery by the
         Underwriters to the Company of any ABS Term Sheets required to be
         delivered in accordance with subsection (iv) above, or in the delivery
         of the accountant's comfort letter in respect thereof pursuant to
         Section 5(xii), the Company shall have the right to delay the release
         of the Prospectus to investors or to the Underwriters, to delay the
         Closing Date and to take other appropriate actions in each case as
         necessary in order to allow the Company to comply with its agreement
         set forth in Section 5(xii) to file the ABS Term Sheets by the time
         specified therein.

         5. Certain Agreements of the Company. The Company agrees with the
Underwriters that:

                  (i) Immediately following the execution of this Agreement, the
         Company will prepare a Prospectus Supplement setting forth the amount
         of Securities covered thereby and the terms thereof not otherwise
         specified in the Basic Prospectus, the price at which such Securities
         are to be purchased by the Underwriters, the initial public offering
         price, the selling concessions and allowances, and such other
         information as the Company deems appropriate and shall furnish a copy
         to the Representative in accordance with Section 5(vii) of this
         Agreement. The Company will transmit the Prospectus including such
         Prospectus Supplement to the Commission pursuant to Rule 424(b) by a
         means reasonably calculated to result in filing that complies with all
         applicable provisions of Rule 424(b). The Company will advise the
         Representative promptly of any such filing pursuant to Rule 424(b).

                  (ii) Prior to the termination of the offering of the
         Securities, the Company will not file any amendment of the Registration
         Statement or supplement to the Prospectus unless the Company has
         furnished the Representative with a copy for its review prior to filing
         and will not file any such proposed amendment or supplement without the
         Representative's consent, which consent will not unreasonably be
         withheld. Subject to the foregoing sentence, if filing of the
         Prospectus is otherwise required under Rule 424(b), the Company will
         file the Prospectus, properly completed, and any supplement thereto,
         with the Commission pursuant to and in accordance with the applicable
         paragraph of Rule 424(b) within the time period prescribed and will
         provide evidence satisfactory to the Representative of such timely
         filing.

                  (iii) The Company will advise the Representative promptly of
         any proposal to amend or supplement the Registration Statement as filed
         or the Prospectus, and will


                                       8
<PAGE>   9

         not effect such amendment or supplement without the Representative's
         consent, which consent will not unreasonably be withheld. The Company
         will also advise the Representative promptly of any request by the
         Commission for any amendment of or supplement to the Registration
         Statement or the Prospectus or for any additional information and the
         Company will also advise the Representative promptly of any amendment
         or supplement to the Registration Statement or the Prospectus and of
         the issuance by the Commission of any stop order suspending the
         effectiveness of the Registration Statement or the institution or
         threat of any proceeding for that purpose, and the Company will use its
         best efforts to prevent the issuance of any such stop order and to
         obtain as soon as possible the lifting of any issued order.

                  (iv) The Company will use every reasonable effort to cause the
         Registration Statement, and any amendment thereto, if not effective at
         the Execution Time, to become effective.

                  (v) If, at any time when a Prospectus relating to the
         Securities is required to be delivered under the Act, any event occurs
         as a result of which the Prospectus as then amended or supplemented
         would include an untrue statement of a material fact or omit to state
         any material fact necessary to make the statements therein, in the
         light of the circumstances under which they were made, not misleading,
         or if it is necessary at any time to amend the Prospectus to comply
         with the Act, the Company promptly will prepare and file with the
         Commission (subject to the Representative's prior review pursuant to
         paragraph (ii) of this Section 5) an amendment or supplement which will
         correct such statement or omission or an amendment or supplement which
         will effect such compliance.

                  (vi) As soon as practicable, the Company will cause the Trust
         to make generally available to the Securityholders of the Trust an
         earnings statement or statements of the Trust covering a period of at
         least 12 months beginning after the Closing Date which will satisfy the
         provisions of Section 11(a) of the Act and Rule 158 of the Commission
         promulgated thereunder.

                  (vii) The Company will furnish to each Underwriter copies of
         the Registration Statement, the Prospectus and any preliminary
         Prospectus Supplement related thereto and all amendments and
         supplements to such documents, in each case as soon as available and in
         such quantities as each Underwriter may reasonably request.

                  (viii) The Company will cooperate with each Underwriter in
         arranging for the qualification of the Securities for sale and the
         determination of their eligibility for investment under the laws of
         such jurisdictions as each Underwriter designates and will continue
         such qualifications in effect so long as required for the distribution
         of the Securities; provided, however, that the Company shall not be
         obligated to qualify to do business in any jurisdiction in which it is
         not currently so qualified or to take any action which would subject it
         to general or unlimited service of process in any jurisdiction where it
         is not now so subject. The Company will promptly advise the
         Underwriters of the receipt by the Company of any notification with
         respect to the suspension or the


                                       9
<PAGE>   10

         qualification of the Securities for sale in any jurisdiction or the
         initiation or threat of any proceeding for such purpose.

                  (ix) For a period from the date of this Agreement until the
         retirement of the Securities, the Company will furnish to the
         Underwriters copies of the annual statements of compliance delivered to
         the Indenture Trustee pursuant to Section 3.09 of the Indenture and
         Section 3.10 of the Servicing Agreement, and the annual independent
         public accountant's reports furnished to the Indenture Trustee pursuant
         to Section 3.11 of the Servicing Agreement, as soon as practicable
         after such statements and reports are furnished to the Indenture
         Trustee and Owner Trustee respectively.

                  (x) So long as any of the Securities are outstanding, the
         Company will furnish to you as soon as practicable, (A) all documents
         distributed, or caused to be distributed, by the Servicer to the
         Securityholders, (B) all documents filed, or caused to be filed, by the
         Company with the Commission pursuant to the Securities Act of 1934, as

         "no-action" letter from the staff of the Commission and (C) from time
         to time, such other information in the possession of the Company
         concerning the Trust and any other information concerning the Company
         filed with any governmental or regulatory authority which is otherwise
         publicly available as you may reasonably request.

                  (xi) (A) On or before the Closing Date the Company shall cause
         its computer records relating to the Funded Contracts to be marked to
         show the Trust's absolute ownership of the Funded Contracts and shall
         cause the Servicer to mark its computer records relating to the Funded
         Contracts to show the sale to the Company of the Funded Contracts and
         the subsequent transfer of the Funded Contracts to the Trust, and from
         and after the Closing Date the Company shall not, and shall instruct
         the Servicer not to, take any action inconsistent with the Trust's
         ownership of such Funded Contracts, other than as permitted by the
         Indenture and the Trust Agreement.

                           (B) On or before the related Prefunding Closing Date,
                  the Company shall cause its computer records for the related
                  Prefunded Contracts to be marked to show the Trust's absolute
                  ownership of the related Prefunded Contracts and shall cause

                  related Prefunded Contracts and the subsequent transfer of the
                  related Prefunded Contracts to the Trust, and after the
                  related Prefunding Closing Date, the Company shall not, and
                  shall instruct the Servicer not to, take any action
                  inconsistent with the Trust's ownership of such Prefunded
                  Contracts, other than as permitted by the Indenture and the
                  Trust Agreement.

                  (xii) The Company will file with the Commission as part of a
         current report on Form 8-K each ABS Term Sheet provided to the Company
         by each of the Underwriters and identified by each of them as such

                  the Servicing Agreement, the Administration Agreement and the
                  Insurance Agreement constitutes the legal, valid and binding
                  agreement of the Company, enforceable against the Company in
                  accordance with its terms, subject, as to enforcement, to (1)
                  the effect of bankruptcy, insolvency, reorganization,
                  moratorium, fraudulent or preferential conveyance and other
                  similar laws of general application relating to or affecting
                  creditors' rights generally, and general principles of equity
                  (regardless of whether such enforceability is considered in a
                  proceeding in equity or at law); and (2) the unenforceability
                  under certain circumstances of provisions indemnifying a party
                  against liability where such indemnification is contrary to
                  public policy;

                           (l) The Registration Statement became effective under
                  the Act as of the date and time specified in such opinion;
                  after due inquiry, to the best of such counsel's knowledge, no
                  stop order suspending the effectiveness of the Registration
                  Statement has been issued and no proceedings for that purpose
                  have been instituted or are pending or contemplated under the
                  Act; the Registration Statement, and each amendment thereof or
                  supplement thereto as of its Effective Date and the Prospectus
                  as of its date of issuance appeared on its face to be
                  appropriately responsive in all material respects to the
                  applicable requirements of


                                       14

                  the Securities Act and the Rules and Regulations, and such
                  counsel need not opine as to the financial statements and
                  related notes, schedules and other financial and statistical
                  data included therein; and any required filing of the
                  Prospectus and Prospectus Supplement pursuant to Rule 424(b)
                  has been made;

                           (m) The Securities, the Indenture, the Trust
                  Agreement, the Servicing Agreement, the Purchase Agreement,
                  and the Guarantee conform in all material respects to the
                  descriptions thereof contained in the Registration Statement
                  and the Prospectus;

                           (n) The Trust Agreement is not required to be
                  qualified under the Trust Indenture Act of 1939, as amended;

                           (o) The Indenture has been duly qualified under the
                  Trust Indenture Act;

                           (p) The Company is not, and after giving effect to
                  the offering and sale of the Securities as contemplated in the
                  Prospectus and this Agreement and the application of the
                  proceeds thereof as described in the Prospectus will not be,
                  an "investment company" as defined in the Investment Company
                  Act of 1940, as amended (the "Investment Company Act"). Onyx
                  is not an "investment company" within the meaning of the
                  Investment Company Act;

                           (q) The Trust is not now, and immediately following
                  the sale of the Securities pursuant to this Agreement will not
                  be, required to be registered under the Investment Company
                  Act;

                           (r) The Indenture, the Sale and Servicing Agreement
                  and the Administration Agreement, assuming that they have been
                  duly authorized by, and when duly executed and delivered by,
                  the Owner Trustee on behalf of the Trust, will constitute the
                  legal, valid and binding obligations of the Trust, enforceable
                  against the Trust in accordance with their terms, except (x)
                  the enforceability thereof may be subject to bankruptcy,
                  insolvency, reorganization, moratorium, fraudulent or other
                  preferential conveyance and other similar laws and other
                  similar laws of general application relating to or affecting
                  the rights of creditors generally and to general principles of
                  equity (regardless of whether such enforcement is considered
                  in a proceeding in equity or at law);

                           (s) all actions required to be taken, and all filings
                  required to be made, by the Company under the Act and the
                  Exchange Act prior to the sale of the Securities have been
                  duly taken or made; and

                           (t) to such counsel's knowledge and information,
                  there are no legal or governmental proceedings pending or
                  threatened that are required to be disclosed in the
                  Registration Statement, other than those disclosed therein.

                  In addition, such counsel shall opine, in form and substance
         satisfactory to you, (i) as to certain matters relating to the
         acquisition by the Company of a perfected first priority security
         interest in the vehicles financed by the Funded Contracts and (ii) as
         to


                                       15
<PAGE>   16

         the existence of a valid, perfected, first priority security interest
         in the Funded Contacts in favor of the Owner Trustee from the Company
         and in favor of the Indenture Trustee from the Owner Trustee.

                  In rendering such opinion, such counsel may rely (i) as to
         matters of fact, to the extent deemed proper and as stated therein, on
         certificates of responsible officers of the Company and public
         officials and (ii) on other opinions of counsel as specified therein.
         References to the Prospectus in this paragraph (iv) include any
         supplements thereto.

                  (v) The Underwriters shall have received an opinion, dated the
         Closing Date, of Andrews & Kurth L.L.P., counsel to Onyx, substantially
         to the effect that:

                           (a) Onyx (1) is duly incorporated and is validly
                  existing and in good standing under the laws of the State of
                  its incorporation, (2) has the corporate power and corporate
                  authority to own its properties and conduct its business as
                  described in the Prospectus and (3) had at all relevant times,
                  and now has, the power, authority and legal right to acquire,
                  own and sell the Funded Contracts;

                           (b) Onyx has the corporate power and corporate
                  authority to execute and deliver the Servicing Agreement, the
                  Insurance Agreements, the Administration Agreement and the
                  Purchase Agreement, to the extent applicable, and at the time
                  it was executed and delivered, had the power and authority to
                  execute and deliver the Purchase Agreement, the Insurance
                  Agreements, the Servicing Agreement and the Administration
                  Agreement to the extent applicable, and to consummate the
                  transactions contemplated herein and therein;

                           (c) No consent, approval, authorization or order of,
                  or filing with, any California or federal governmental agency
                  or body or any court is required by Onyx to perform the
                  transactions contemplated by the Insurance Agreements, the
                  Servicing Agreement, the Administration Agreement or the
                  Purchase Agreement, as applicable, except for (1) filing of a
                  Uniform Commercial Code financing statement in the State of
                  California with respect to the sales of the Funded Contracts
                  to the Company pursuant to the Purchase Agreement and (2) such
                  consents, approvals, authorizations, orders or filings as may
                  be required under the federal and state securities laws; the
                  opinion set forth in this sentence is limited to such
                  authorizations, approvals, consents and orders which, in such
                  counsel's experience, are normally applicable to transactions
                  of the type contemplated by the Insurance Agreements, the
                  Servicing Agreement, the Administration Agreement and the
                  Purchase Agreement, as applicable;

                           (d) None of the execution, delivery and performance
                  by Onyx of the Servicing Agreement, the Insurance Agreements,
                  the Administration Agreement or the Purchase Agreement, as
                  applicable, or the transfer of the Funded Contracts to the
                  Company, has conflicted with or will conflict with, has
                  resulted or will result in a breach, violation or acceleration
                  of any of the terms of, or has constituted or will constitute
                  a default under, the By-Laws or the Certificate of
                  Incorporation of Onyx, as amended, or, to the best of such
                  counsel's knowledge,


                                       16

                  any rule, order, statute or regulation known to such counsel
                  to be currently applicable to Onyx of any court, regulatory
                  body, administrative agency or governmental body having
                  jurisdiction over Onyx or the terms of any material indenture
                  or other material agreement or instrument known to such
                  counsel to which Onyx is a party or by which it or its
                  properties are bound;

                           (e) The Servicing Agreement, the Insurance
                  Agreements, the Administration Agreement and the Purchase
                  Agreement have each been duly authorized, executed and
                  delivered by Onyx;

                           (f) The indemnification agreement dated as of the
                  date hereof, between Onyx and the Representative has been duly
                  authorized, executed and delivered by Onyx; and

                           (g) Assuming the authorization, execution and
                  delivery thereof by the Company with respect to the Servicing
                  Agreement, the Insurance Agreement, the Administration
                  Agreement and the Purchase Agreement, as applicable, each such
                  agreement constitutes the legal, valid and binding agreement
                  of Onyx, enforceable against Onyx in accordance with its
                  terms, subject, as to enforcement, to (1) the effect of
                  bankruptcy, insolvency, reorganization, moratorium, fraudulent
                  or preferential conveyance and other similar laws of general
                  application relating to or affecting creditors' rights
                  generally and general principles of equity (regardless of
                  whether such enforceability is considered in a proceeding in
                  equity or at law); and (2) the unenforceability under certain
                  circumstances of provisions indemnifying a party against
                  liability where such indemnification is contrary to public
                  policy.

                  In rendering such opinion, such counsel may rely as to matters
         of fact, to the extent deemed proper and as stated therein, on
         certificates of responsible officers of Onyx and public officials.

         In addition, such counsel shall state that they have participated in
conferences with the officers and other representatives of the Company and Onyx,
representatives of the independent public accountants of the Company and Onyx
and representatives of the Underwriters and the Insurer at which the contents of
the Registration Statement and the Prospectus and related matters were discussed
and, although such counsel has not independently verified and are not passing
upon and do not assume any responsibility for, the accuracy, completeness or
fairness of the statements contained in the Registration Statement and the
Prospectus, on the basis of the foregoing, no facts have come to such counsel's
attention that lead them to believe that the Registration Statement, as of the
Effective Date, 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, or that the Prospectus as of its date or as
of the Closing Date contained or contains an untrue statement of a material fact
or omitted or omits 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 (it being understood that such counsel need make no comment
and express no belief with respect to (i) any information incorporated by
reference in the Registration Statement or the Prospectus or (ii) the financial
statements and related notes,


                                       17

Registration Statement or the Prospectus).

         & Kurth L.L.P., counsel to the Company, dated the Closing Date and
         satisfactory in form and substance to you, with respect the
         characterization of the transfer of the Funded Contracts by Onyx to the
         Company as a sale and with respect to the perfection of the Trust's
         interests in the Funded Contracts and with respect to the
         non-consolidation of the Company with Onyx in the event of bankruptcy
         filing with respect to Onyx and with respect to certain other matters.

                  (vii) The Underwriters shall have received an opinion of
         Andrews & Kurth L.L.P., tax counsel to the Company, dated the Closing
         Date and satisfactory in form and substance to you substantially to the
         effect that:

                           (a) The Notes will be characterized as debt and the
                  Trust will not be characterized as an association (or a
                  publicly traded partnership) taxable as a corporation;

                           (b) the Statements in the Base Prospectus under the

                  INCOME TAX CONSEQUENCES"; "TRUSTS FOR WHICH A PARTNERSHIP
                  ELECTION IS MADE" and "TRUSTS TREATED AS GRANTOR TRUSTS" and

                  TERMS -- Federal Income Tax Status" and "CERTAIN FEDERAL
                  INCOME TAX CONSEQUENCES" to the extent that they constitute
                  matters of law or legal conclusions with respect thereto, have
                  been prepared or reviewed by such counsel and are correct in
                  all material respects; and

                           (c) Such state tax opinions as are satisfactory to
                  the Representative.

                  (viii) The Underwriters shall have received an opinion of
         Michael Krahelski, in-house counsel to the Company and Onyx, dated the
         Closing Date and satisfactory in form and substance to you.

                  good standing and licensed to transact the business of surety

                  authorization, consent, approval, license, formal exemption or
                  declaration from, nor any registration or filing with, any
                  court or governmental agency or body of the United States of
                  America or the State of New York, which if not obtained would
                  affect or impair the validity or enforceability of the
                  Guarantee, the Insurance Agreement or the MBIA Indemnification
                  Agreement against the Insurer, is required in connection with
                  the execution and delivery by the Insurer of the Guarantee,
                  the Insurance Agreement or the MBIA Indemnification Agreement
                  or in connection with the Insurer's performance of its

                           (d) The Guarantee, the Insurance Agreement and the
                  MBIA Indemnification Agreement have been duly authorized,
                  executed and delivered by the Insurer, and the Guarantee and,

                  accordance with their respective terms subject, as to
                  enforcement, to (1) bankruptcy, reorganization, insolvency,
                  moratorium and other similar laws relating to or affecting the
                  enforcement of creditors' rights generally, including, without

                  subordination, presently or from time to time in effect and

                  enforcement is considered in a proceeding in equity or at
                  law), as such laws may be applied in any such proceeding with
                  respect to the Insurer and (2) the qualification that the

         set forth in or contemplated by the Prospectus or as described in such
         certificate.

                  (xviii) The Guarantee shall have been duly authorized,
         executed, issued and delivered by the Insurer; all fees due and payable
         to the Insurer as of the Closing Date shall have been paid in full; and
         the Guarantee shall conform to the description thereof in the

                  (xix) The Underwriters shall have received a certificate from

         supplement thereto as of its Effective Date or date of issuance, as the
         case may be, contained any untrue statement of a material fact or
         omitted to state any material fact required to be stated therein or
         necessary to make the statements therein, in light of the circumstances
         under which they were made, not misleading.

         The Company will furnish or cause to be furnished to the Underwriters
such number of conformed copies of such opinions, certificates, letters and
documents as the Underwriters reasonably request.

         8. Indemnification.

                  (i) The Company will indemnify and hold harmless each
         Underwriter and each person, if any, who controls such Underwriter
         within the meaning of Section 15 of the Act against any losses, claims,
         damages or liabilities, joint or several, to which such Underwriter may
         become subject, under the Act or otherwise, insofar as such losses,
         claims, damages or liabilities (or actions in respect thereof) (a)
         arise out of, or are based upon, any untrue statement or alleged untrue
         statement of any material fact contained in the Registration Statement,
         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 not misleading or (b) arise
         out of, or are based upon, any untrue statement or alleged untrue
         statement of any material fact contained in the Prospectus or arise out
         of, or are based upon, the omission or alleged omission to state
         therein a material fact necessary to make the statements therein, in
         light of the circumstances under which they were made, not misleading;
         and will reimburse each Underwriter for any legal or other expenses
         reasonably incurred, as incurred, by each Underwriter in connection
         with investigating or defending any such action or claim; provided,
         however, that the Company shall not be liable in any such case to the
         extent that any such loss, claim, damage or liability arises out of, or
         is based upon, an untrue statement or alleged untrue statement or
         omission or alleged omission (x) made in the Registration Statement or
         the Prospectus or any such amendment or supplement in reliance upon and
         in conformity with written information furnished to the Company by the
         Underwriters expressly for use therein, or (y) contained in any ABS
         Term Sheet to the extent set forth in subsection (ii) of this Section
         8; provided, further, that the Company shall not be liable under this
         subsection (i) to the extent that such losses, claims, damages or
         liabilities arose out of or are based upon an untrue statement or
         omission made in any preliminary prospectus that is corrected in the
         final Prospectus (or any amendment or supplement thereto), and the
         Company has previously furnished copies thereof in sufficient quantity
         to the Underwriters, if the person asserting such loss, claim, damage
         or liability was not given


                                       21
<PAGE>   22

         the final Prospectus (or any amendment or supplement thereto) on or
         prior to the confirmation of the sale of the Securities.

                  (ii) Each Underwriter, severally and not jointly, agrees to
         indemnify and hold harmless the Company, its directors, each of its
         officers or agents who signed the Registration Statement, and each
         person, if any, who controls the Company within the meaning of Section
         15 of the Act against any and all loss, liability, claim, damage and
         expense described in the indemnity contained in subsection (i) of this
         Section 8, as incurred, but only with respect to untrue statements or
         omissions, or alleged untrue statements or omissions, (A) made in the
         Registration Statement (or any amendment thereto) or any preliminary
         prospectus or the Prospectus (or any amendment or supplement thereto)
         in reliance upon and in conformity with written information furnished
         to the Company by the Underwriters through the Representative expressly
         for use in the Registration Statement (or any amendment thereto) or any
         preliminary prospectus or the Prospectus (or any amendment or
         supplement thereto) or (B) made in the ABS Term Sheets distributed by
         the Underwriters and filed as a post-effective amendment to the
         Registration Statement or the Prospectus or as a result of any filing
         pursuant to Section 5(xii); provided -------- however that the
         Underwriters will not be liable in any such case to the extent that any
         such loss, claim or damage or liability arises out of, or is based
         upon, an untrue statement or omission made in the ABS Term Sheet or any
         supplement thereto in reliance upon and in conformity with (x)
         information furnished to such Underwriter by the Company or (y)
         information contained in the Registration Statement or any preliminary
         prospectus or the Prospectus other than information described in clause
         (A) above.

                  (iii) Each indemnified party shall give prompt notice to the
         indemnifying party of any action commenced against the indemnified
         party in respect of which indemnity may be sought hereunder, but
         failure to so notify an indemnifying party shall not relieve such
         indemnifying party from any liability which it may have hereunder or
         otherwise than on account of this indemnity agreement except and to the
         extent of any prejudice to such indemnifying party arising from such
         failure to provide such notice. In case any such action shall be
         brought against an indemnified party and it shall have notified the
         indemnifying party of the commencement thereof, the indemnifying party
         shall be entitled to participate therein and, to the extent that it
         shall wish, to assume the defense thereof, with counsel, satisfactory
         to such indemnified party (who shall not, except with the consent of
         the indemnified party, be counsel to the indemnifying party with
         respect to such action), and it being understood that 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, and, after notice from the indemnifying party to the
         indemnified party of its election so to assume the defense thereof, the
         indemnifying party shall not be liable to the indemnified party under
         subsections (i) or (ii) of this Section 8 for any legal expenses of
         other counsel or any other expenses, in each case subsequently incurred
         by the indemnified party, in connection with the defense thereof other
         than reasonable costs of investigation.


                                       22
<PAGE>   23

         9. Contribution. In order to provide for just and equitable
contribution in circumstances in which the indemnity agreement provided for in
Section 8 is for any reason held to be unavailable other than in accordance with
its terms, then each indemnifying party shall contribute to the amount paid or
payable by such indemnifying party as a result of the losses, claims, damages or
liabilities referred to in 8(i) and 8(ii) above (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company on the one
hand and each Underwriter on the other from the offering of the Securities or
(ii) if the allocation provided by clause (i) above is not permitted by
applicable law, 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 of the related Underwriter on the other in
connection with the statements or omissions which resulted in such losses,
claims, damages or liabilities as well as any other relevant equitable
considerations. The relative benefits received by the Company on the one hand
and each Underwriter on the other shall be deemed to be in the same proportion
as the total net proceeds from the offering (before deducting expenses) received
by the Company bear to the total underwriting discounts and commissions received
by each Underwriter. The relative fault shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact relates to
information supplied by the Company or by the related Underwriter and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such untrue statement or omission. The amount paid by an
indemnified party as a result of the losses, claims, damages or liabilities
referred to in the first sentence of this Section 9 shall be deemed to include
any legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any action or claim which is the
subject of this Section 9. Notwithstanding the provisions of this Section 9, no
Underwriter shall be required to contribute any amount in excess of the
underwriting discount or commission applicable to the Securities purchased by it
hereunder. The Company and each Underwriter agrees that it would not be just and
equitable if contribution pursuant to this Section 9 were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to above in this Section 9. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Act) shall be entitled to contribution from any person who was not guilty of
such fraudulent misrepresentation.

         10. Termination. The Underwriters may terminate this Agreement
immediately upon notice to the Company, if at any time, prior to the Closing
Date, there has occurred: (a) any change, or any development involving a
prospective change, in or affecting particularly the business or properties of
the Company or Onyx which, in the reasonable judgment of the Underwriters,
materially impairs the investment quality of the Securities; (b) any suspension
or material limitation of trading in securities generally on the New York Stock
Exchange, or any setting of minimum prices for trading on such exchange, or any
suspension of trading of any securities of the Company or of Onyx on any
exchange or in the over-the-counter market by such exchange or over-the-counter
market or by the Commission; (c) any banking moratorium declared by Federal, New
York or California authorities; or (d) any outbreak or material escalation of
major hostilities or any other substantial national or international calamity or
emergency if, in the reasonable judgment of the Underwriters, the effect of any
such outbreak, escalation, calamity or emergency on the United States financial
markets makes it impracticable or inadvisable to proceed with completion of the
sale of and any payment for the Securities.

         11. Survival of Certain Representations and Obligations. The respective
indemnities, agreements, representations, warranties and other statements of the
Company or its officers and of the Underwriters set forth in or made pursuant to
this Agreement will remain in full force and effect, regardless of any
investigation, or statement as to the results thereof, made by or on behalf of
the Underwriters, the Company or any of their respective representatives,
officers or directors or any controlling person, and will survive delivery of
and payment for the Securities. If for any reason the purchase of the Securities
by the Underwriters is not consummated, the Company shall remain responsible for
the expenses to be paid or reimbursed by it pursuant to Section 6 and the
respective obligations of the Company and the Underwriters pursuant to Sections
6, 8 and 9 shall remain in effect. If the purchase of the Securities by the
Underwriters is not consummated for any reason other than solely because of the
occurrence of any event specified in clauses (b), (c) or (d) of Section 7(iii)
or clauses (b), (c) or (d) of Section 10, and other than solely because the
Underwriters fail to perform their obligations hereunder, the Company will
reimburse the Underwriter for all out-of-pocket expenses (including fees and
disbursements of counsel) reasonably incurred by it in connection with the
offering of the Securities.

         12. Notices. All communications hereunder will be in writing and, if
sent to the Representative, will be mailed, delivered or telegraphed and
confirmed to the Representative at Salomon Smith Barney Inc., 390 Greenwich

the Company at Onyx Acceptance Financial Corporation, 27051 Towne Centre Drive,
Suite 200, Foothill Ranch, CA 92610, Attention: Michael A. Krahelski, Esq.,
Senior Vice President and General Counsel.

         13. Successors. This Agreement will inure to the benefit of, and be
binding upon, the parties hereto and their respective successors. Nothing
expressed or mentioned in this Agreement is intended or shall be construed to
give any person, firm or corporation, other than the parties hereto and their
respective successors and the controlling persons and officers and directors
referred to in Sections 8 and 9 and their heirs and legal representatives, any
legal or equitable right, remedy or claim under or in respect of this Agreement
or any provision herein contained. This Agreement and all conditions and
provisions hereof are intended to be for the sole and exclusive benefit of the
parties hereto and their respective successors, and said controlling persons and
officers and directors and their heirs and legal representatives, and for the
benefit of no other person, firm or corporation. No purchaser of Securities from
the Underwriters shall be deemed to be a successor by reason merely of such
purchase.

         14. Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all such
counterparts shall together constitute one and the same Agreement.

         15. APPLICABLE LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED
IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

         16. Severability of Provisions. Any covenant, provisions, agreement or
term of this Agreement that is prohibited or is held to be void or unenforceable
in any jurisdiction shall, as to


                                       24
<PAGE>   25

such jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof.

         17. Entire Agreement. This Agreement constitutes the entire agreement
and understanding of the parties hereto with respect to the matters and
transactions contemplated hereby and supersedes all prior agreements and
understandings whatsoever relating to such matters and transactions.

         18. Amendment. Neither this Agreement nor any term hereof may be
changed, waived, discharged or terminated orally, but only by an instrument in
writing signed by the party against whom enforcement of the change, waiver,
discharge or termination is sought.

         19. Heading. The headings in this Agreement are for the purposes of
reference only and shall not limit or otherwise affect the meaning hereof.

         20. The Representative. The Representative will act for the several
Underwriters in connection with the transactions described in this Agreement,
and any action taken by the Representative under this Agreement will be binding
upon all the Underwriters.

         21. Defaults of Underwriters. If any Underwriter defaults in its
obligation to purchase the Certificates hereunder on the Closing Date and the
aggregate principal amount of the Securities that such defaulting Underwriter
agreed but failed to purchase does not exceed 10% of the total principal amount
of the Securities, the Representative may make arrangements satisfactory to the
Representative and the Company for the purchase of such Securities by other
persons, including either of the Underwriters, but if no such arrangements are
made by the Closing Date, the nondefaulting Underwriter shall be obligated, in
proportion to its respective commitment hereunder, to purchase the Securities
that such defaulting Underwriter agreed but failed to purchase. If an
Underwriter so defaults and the aggregate principal amount of the Securities
with respect to such default exceeds 10% of the total principal amount of the
Securities and arrangements satisfactory to the Representative and the Company
for the purchase of such Securities by other persons are not made within 24
hours after such default, this Agreement will terminate without liability on the
part of the nondefaulting Underwriter or the Company, except as provided in
Section 11. Nothing herein will relieve a defaulting Underwriter from liability
for its default.

the same Class in any authorized denominations, of a like aggregate principal
amount, upon surrender of the Notes to be exchanged at such office or agency.
Whenever any Notes are so surrendered for exchange, the Issuer shall execute,

exchange shall be duly endorsed by, or be accompanied by a written instrument of
transfer in form satisfactory to the Indenture Trustee duly executed by, the
Holder thereof or such Holder's attorney duly authorized in writing, with such

correspondent located, in the city of New York or the city in which the

charge that may be imposed in connection with any registration of transfer

Trustee receives evidence to its satisfaction of the destruction, loss or theft
of any Note, and (ii) there is delivered to the Indenture Trustee and the
Insurer (unless an Insurer Default shall have occurred and be continuing) such
security or indemnity as may be required by them to hold the Issuer, the
Indenture Trustee and the Insurer harmless, then, in the absence of notice to
the Issuer, the Note Registrar or the Indenture Trustee that such Note has been
acquired by a bona fide purchaser, the Issuer shall execute and upon its request
the Indenture Trustee shall authenticate and deliver, in exchange for or in lieu
of any such mutilated, destroyed, lost or stolen Note, a replacement Note of the
same Class; provided, however, that if any such destroyed, lost or stolen Note,
but not a mutilated Note, shall have become or within seven days shall be due
and payable, or shall have been called for redemption, instead of issuing a
replacement Note, the Issuer may pay such destroyed, lost or stolen Note when so
due or payable or upon the Redemption Date without surrender thereof. If, after
the delivery of such replacement Note or payment of a destroyed, lost or stolen
Note pursuant to the proviso to the preceding sentence, a bona fide purchaser of
the original Note in lieu of which such replacement Note was issued presents for
payment such original Note, the Issuer, the Insurer and the Indenture Trustee
shall be entitled to recover such replacement Note (or such payment) from the
Person to whom it was delivered or any Person taking such replacement Note from
such Person to whom such replacement Note was delivered or any assignee of such
Person, except a bona fide purchaser, and shall be entitled to recover upon the
security or indemnity provided therefor to the extent of any loss, damage, cost
or expense incurred by the Issuer, the Insurer or the Indenture Trustee in
connection therewith.

         Upon the issuance of any replacement Note under this Section, the
Issuer or the Indenture Trustee may require the payment by the Holder of such
Note of a sum sufficient to cover any tax or other governmental charge that may
be imposed in relation thereto and any other reasonable expenses (including the
fees and expenses of the Indenture Trustee or the Note Registrar) connected
therewith.

         Every replacement Note issued pursuant to this Section in replacement
of any mutilated, destroyed, lost or stolen Note shall constitute an original
additional contractual obligation of the Issuer, whether or not the mutilated,
destroyed, lost or stolen Note shall be at any time enforceable by anyone, and
shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Notes duly issued hereunder.

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

                  (a) Each Class of Notes shall accrue interest during each
Interest Accrual Period at the related Interest Rate, and such interest shall be
payable on each Distribution Date as specified therein, subject to Section 3.01.
Interest accrued on any Note but not paid on any Distribution Date will be due
on the immediately succeeding Distribution Date, together with, to the extent
permitted by applicable law, interest on such shortfall at the related Interest
Rate. Interest on the Notes shall be calculated on the basis of a 360-day year
of twelve 30-day months, except for the Class A-1 Notes, which shall be
calculated on the basis of a 360-day year and the actual number of days in the
related Interest Accrual Period. Any installment of interest or principal, if
any, payable on any Note which is punctually paid or duly provided for by the
Issuer on the applicable Distribution Date shall be paid to the Person in whose
name such Note (or one or more Predecessor Notes) is registered on the Record
Date, by check mailed first-class, postage prepaid to such Person's address as
it appears on the Note Register on such Record Date, except that, unless
Definitive Notes have been issued pursuant to Section 2.11, with respect to
Notes registered on the Record Date in the name of the nominee of the Clearing
Agency (initially, such nominee to be Cede & Co.), payment will be made by wire
transfer in immediately available funds to the account designated by such
nominee and except for the final installment of principal payable with respect
to such Note on a Distribution Date, a Redemption Date or on the related Final
Scheduled Distribution Date, as the case may be (and except for the Redemption
Price for any Note called for redemption pursuant to Section 10.01), which shall
be payable as provided below. The funds represented by any such checks returned
undelivered shall be held in accordance with Section 3.03.

                  (b) The principal of each Note shall be payable on each
Distribution Date to the extent provided in the form of the related Note set
forth as an Exhibit hereto. Notwithstanding the foregoing, the entire unpaid
principal amount of the Notes of a Class of Notes shall be due and payable, if
not previously paid, on the earlier of:

                           (i) the Final Scheduled Distribution Date of such
         Class;

                           (ii) the Redemption Date;

                           (iii) if an Event of Default shall have occurred and
         be continuing, so long as an Insurer Default shall not have occurred
         and be continuing, the date on which the Insurer shall have declared
         the Notes to be immediately due and payable in the manner provided in
         Section 5.02; or

                           (iv) if an Event of Default shall have occurred and
         be continuing and if an Insurer Default has occurred and is continuing,
         the date on which the Holders of Notes representing not less than
         662/3% of the Outstanding Amount have declared the Notes to be
         immediately due and payable in the manner provided in Section 5.02.



                                      -11-
<PAGE>   17

All principal payments on each Class of Notes shall be made pro rata to the
Noteholders of such Class entitled thereto. The Indenture Trustee shall notify
the Person in whose name a Note is registered at the close of business on the
Record Date preceding the Distribution Date on which the Issuer expects that the
final installment of principal of, and interest on, such Note will be paid. Such
notice shall be mailed within five Business Days of such Distribution Date (or,
in the case of Notes registered in the name of Cede & Co., as nominee of DTC,
such notice shall be provided within one Business Day of such Distribution Date)
or receipt of notice of termination of the Trust pursuant to Section 9.01(c) of
the Trust Agreement and shall specify that such final installment will be
payable only upon presentation and surrender of such Note and shall specify the
place where such Note may be presented and surrendered for payment of such
installment. Notices in connection with redemptions of Notes shall be mailed to
Noteholders as provided in Section 10.02. In addition, the Administrator shall
notify the Insurer and the Rating Agencies upon the final payment of interest
and principal of each Class of Notes, and upon the termination of the Trust, in
each case pursuant to the Administration Agreement.

                  Section 2.08 Cancellation. All Notes surrendered for payment,
registration of transfer, exchange or redemption shall, if surrendered to any
Person other than the Indenture Trustee, be delivered to the Indenture Trustee
and shall be promptly canceled by the Indenture Trustee. The Issuer may at any
time deliver to the Indenture Trustee for cancellation any Notes previously
authenticated and delivered hereunder which the Issuer may have acquired in any
manner whatsoever, and all Notes so delivered shall be promptly canceled by the
Indenture Trustee. No Notes shall be authenticated in lieu of or in exchange for
any Notes canceled as provided in this Section, except as expressly permitted by
this Indenture. All canceled Notes may be held or disposed of by the Indenture
Trustee in accordance with its standard retention or disposal policy as in
effect at the time unless the Issuer shall direct by an Issuer Order that they
be destroyed or returned to it; provided that such Issuer Order is timely and
the Notes have not been previously disposed of by the Indenture Trustee.

                  Section 2.09 Book-Entry Notes. The Notes, upon original
issuance, will be issued in the form of a typewritten Note or Notes representing
the Book-Entry Notes, to be delivered to DTC, the initial Depository, by, or on
behalf of, the Issuer. Such Notes shall initially be registered on the Note
Register in the name of Cede & Co., the nominee of the initial Clearing Agency,
and no Note Owner will receive a Definitive Note representing such Note Owner's
interest in such Note, except as provided in Section 2.11. Unless and until
definitive, fully registered Notes (the "DEFINITIVE NOTES") have been issued to
Note Owners pursuant to Section 2.11:

                           (i) the provisions of this Section shall be in full
                  force and effect;

                           (ii) the Note Registrar and the Indenture Trustee
                  shall be entitled to deal with the Clearing Agency for all
                  purposes of this Indenture (including the payment of principal
                  of and interest on the Notes and the giving of instructions or
                  directions hereunder) as the sole Holder of the Notes, and
                  shall have no obligation to the Note Owners;

                           (iii) to the extent that the provisions of this
                  Section conflict with any other provisions of this Indenture,
                  the provisions of this Section shall control;



                                      -12-
<PAGE>   18

                           (iv) the rights of Note Owners shall be exercised
                  only through the Clearing Agency and shall be limited to those
                  established by law and agreements between such Note Owners and
                  the Clearing Agency and/or the Clearing Agency Participants.
                  Pursuant to the Depository Agreement, unless and until
                  Definitive Notes are issued pursuant to Section 2.11, the
                  Clearing Agency will make book-entry transfers among the
                  Clearing Agency Participants and receive and transmit payments
                  of principal of and interest on the Notes to such Clearing
                  Agency Participants; and

                           (v) whenever this Indenture requires or permits
                  actions to be taken based upon instructions or directions of
                  Holders of Notes evidencing a specified percentage of the
                  Outstanding Amount, the Clearing Agency shall be deemed to
                  represent such percentage only to the extent that it has
                  received instructions to such effect from Note Owners and/or
                  Clearing Agency Participants owning or representing,
                  respectively, such required percentage of the beneficial
                  interest in the Notes and has delivered such instructions to
                  the Indenture Trustee.

                  Section 2.10 Notices to Clearing Agency. Whenever a notice or
other communication to the Noteholders is required under this Indenture, unless
and until Definitive Notes shall have been issued to Note Owners pursuant to
Section 2.11, the Indenture Trustee shall give all such notices and
communications specified herein to be given to Holders of the Notes to the
Clearing Agency, and shall have no obligation to the Note Owners.

                  Section 2.11 Definitive Notes. If (i) the Administrator
advises the Indenture Trustee in writing that the Clearing Agency is no longer
willing or able to properly discharge its responsibilities as described in the
Depository Agreement, and the Administrator or the Indenture Trustee is unable
to locate a qualified successor, or (ii) after the occurrence of an Event of
Default or a Servicer Default, Note Owners representing in the aggregate more
than 50% of the Outstanding Amount of all Classes of Notes advise the Indenture
Trustee through the Clearing Agency Participants in writing that the
continuation of a book-entry system through the Clearing Agency is no longer in
the best interests of the related Note Owners, then the Indenture Trustee shall
notify all Note Owners, through the Clearing Agency, of the availability of
Definitive Notes to Note Owners requesting the same. Upon surrender to the
Indenture Trustee of the Note or Notes evidencing the Book Entry Notes by the
Clearing Agency, accompanied by registration instructions from the Clearing
Agency, the Issuer shall execute and the Indenture Trustee shall authenticate
the Definitive Notes and deliver such Definitive Notes in accordance with the
instructions of the Clearing Agency. None of the Issuer, the Note Registrar or
the Indenture Trustee shall be liable for any delay in delivery of such
instructions and may conclusively rely on, and shall be protected in relying on,
such instructions. Upon the issuance of Definitive Notes of a Class, the
Indenture Trustee shall recognize the Holders of the Definitive Notes as
Noteholders hereunder.

         The Indenture Trustee shall not be liable if the Indenture Trustee or
the Administrator is unable to locate a qualified successor Clearing Agency. The
Definitive Notes shall be typewritten, printed, lithographed or engraved or
produced by any combination of these methods (with or without steel engraved
borders), all as determined by the officers executing such Notes, as evidenced
by their execution of such Notes.

                  Section 2.12 Release of Collateral. Subject to Section 11.01
and the terms of the Basic Documents, the Indenture Trustee shall release
property from the lien of this Indenture only



                                      -13-
<PAGE>   19

upon receipt of an Issuer Request accompanied by an Officer's Certificate, an
Opinion of Counsel and Independent Certificates in accordance with Sections
314(c) and 314(d)(1) of the TIA or an Opinion of Counsel in lieu of such
Independent Certificates to the effect that the TIA does not require any such
Independent Certificates.

                  Section 2.13 Tax Treatment. The Issuer has entered into this
Indenture, and the Notes will be issued, with the intention that, for federal,
state and local income, single business and franchise tax purposes, the Notes
will qualify as indebtedness of the Issuer secured by the Collateral. The
Issuer, by entering into this Indenture, and each Noteholder, by its acceptance
of its Note (and each Note Owner by its acceptance of an interest in the
applicable Book-Entry Note), agree to treat the Notes for federal, state and
local income, single business and franchise tax purposes as indebtedness of the
Issuer.

                  Section 2.14 ERISA. Each purchaser or transferee of a Note
that is a Benefit Plan shall be deemed to have represented that the relevant
conditions for exemptive relief under Prohibited Transaction Class Exemption
("PTCE") 84-14, PTCE 90-1, PTCE 91-38, PTCE 95-60 or PTCE 96-23 or other
applicable exemption providing substantially similar relief have been satisfied
or has provided a written representation to the Issuer satisfactory to the
Issuer in lieu thereof.

                                   ARTICLE III

                                    COVENANTS

                  Section 3.01 Payment of Principal and Interest. The Issuer
will duly and punctually pay the principal of and interest, if any, on the Notes
in accordance with the terms of the Notes and this Indenture. Without limiting
the foregoing, subject to Section 8.02(c), the Issuer will cause to be
distributed all amounts on deposit in the Note Distribution Account on a
Distribution Date deposited therein pursuant to the Sale and Servicing Agreement
for the benefit of (i) the Class A-1 Notes, to the Class A-1 Noteholders, (ii)
the Class A-2 Notes, to the Class A-2 Noteholders, (iii) the Class A-3 Notes, to
the Class A-3 Noteholders and (iv) the Class A-4 Notes, to the Class A-4
Noteholders. Amounts properly withheld under the Code by any Person from a
payment to any Noteholder of interest and/or principal shall be considered as
having been paid by the Issuer to such Noteholder for all purposes of this
Indenture.

                  Section 3.02 Maintenance of Office or Agency. The Issuer will
or will cause the Administrator or the Indenture Trustee to maintain in The City
of New York, an office or agency where Notes may be surrendered for registration
of transfer or exchange, and where notices and demands to or upon the Issuer in
respect of the Notes and this Indenture may be served. The Issuer hereby
initially appoints the Indenture Trustee to serve as its agent for the foregoing
purposes. The Issuer will give prompt written notice to the Indenture Trustee of
the location, and of any change in the location, of any such office or agency.
If at any time the Issuer shall fail to maintain any such office or agency or
shall fail to furnish the Indenture Trustee with the address thereof, such
surrenders, notices and demands may be made or served at the Corporate Trust
Office, and the Issuer hereby appoints the Indenture Trustee as its agent to
receive all such surrenders, notices and demands.

                  Section 3.03 Money for Payments to be Held in Trust.

                  (a) As provided in Section 8.02, all payments of amounts due
and payable with respect to any Notes that are to be made from amounts withdrawn
from the the Note Distribution Account (after required transfers thereto from
the other Trust Accounts) shall be made on behalf of the Issuer by the Paying
Agent (including the Indenture Trustee when serving as a Paying Agent), and no
amounts so withdrawn from the Note Distribution Account for payments of Notes
shall be paid over to the Issuer except as provided in this Section.

         The Notes shall be non-recourse obligations of the Issuer and shall be
limited in right of payment to amounts available from the Collateral and the
Policy as provided in this Indenture and the Issuer shall not otherwise be
liable for payments on the Notes. No Person shall be personally liable for any
amounts payable under the Notes. If any other provision of this Indenture
conflicts or is deemed to conflict with the provisions of this paragraph, the
provisions of this paragraph shall control.

         On the Business Day immediately preceding each Distribution Date, the
Servicer shall cause funds to be withdrawn from the Collection Account and
deposited into the Payment Account pursuant to Section 4.02(e) of the Sale and
Servicing Agreement, and on each Distribution Date, the Indenture Trustee shall
make the deposits to the Note Distribution Account required by Section 4.03(a)
of the Sale and Servicing Agreement.

         The Issuer will cause each Paying Agent other than the Indenture
Trustee to execute and deliver to the Indenture Trustee and the Insurer an
instrument in which such Paying Agent shall agree with the Indenture Trustee
(and if the Indenture Trustee acts as Paying Agent, it hereby so agrees),
subject to the provisions of this Section, that such Paying Agent will:

                           (i) hold all sums held by it for the payment of
                  amounts due with respect to the Notes in trust for the benefit
                  of the Persons entitled thereto until such sums shall be paid
                  to such Persons or otherwise disposed of as herein provided
                  and pay such sums to such Persons as herein provided;

                           (ii) give the Indenture Trustee notice of any default
                  by the Issuer (or any other obligor upon the Notes) in the
                  making of any payment required to be made with respect to the
                  Notes;

                           (iii) at any time during the continuance of any such
                  default, upon the written request of the Indenture Trustee,
                  forthwith pay to the Indenture Trustee all sums so held in
                  trust by such Paying Agent;

                           (iv) immediately resign as Paying Agent and forthwith
                  pay to the Indenture Trustee all sums held by it in trust for
                  the payment of Notes if at any time it ceases to meet the
                  standards required to be met by a Paying Agent at the time of
                  its appointment; and

                           (v) comply with all requirements of the Code with
                  respect to the withholding from any payments made by it on any
                  Notes of any applicable withholding taxes imposed thereon and
                  with respect to any applicable



                                      -15-
<PAGE>   21


                  withholding taxes imposed thereon and with respect to any
                  applicable reporting requirements in connection therewith.

         The Issuer may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, by Issuer
Order direct any Paying Agent to pay to the Indenture Trustee all sums held in
trust by such Paying Agent, such sums to be held by the Indenture Trustee upon
the same trusts as those upon which the sums were held by such Paying Agent; and
upon such payment by any Paying Agent to the Indenture Trustee, such Paying
Agent shall be released from all further liability with respect to such money.

         Subject to applicable laws with respect to escheat of funds, any money
held by the Indenture Trustee or any Paying Agent in trust for the payment of
any amount due with respect to any Note and remaining unclaimed for two years
after such amount has become due and payable shall be discharged from such trust
and be paid to the Issuer upon receipt of an Issuer Request; and the Holder of
such Note shall thereafter, as an unsecured general creditor, look only to the
Issuer for payment thereof, and all liability of the Indenture Trustee or such
Paying Agent with respect to such trust money shall thereupon cease; provided,
however, that the Indenture Trustee or such Paying Agent, before being required
to make any such repayment, shall at the expense and direction of the Issuer
cause to be published once, in a newspaper published in the English language,
customarily published on each Business Day and of general circulation in The
City of New York, notice that such money remains unclaimed and that, after a
date specified therein, which shall not be less than 30 days from the date of
such publication, any unclaimed balance of such money then remaining will be
repaid to or for the account of the Issuer. The Indenture Trustee may also adopt
and employ, at the expense of the Issuer, any other reasonable means of
notification of such repayment (including, but not limited to, mailing notice of
such repayment to Holders whose Notes have been called but have not been
surrendered for redemption or whose right to or interest in monies due and
payable but not claimed is determinable from the records of the Indenture
Trustee or of any Paying Agent, at the last address of record for each such
Holder).

                  Section 3.04 Existence. The Issuer will keep in full effect
its existence, rights and franchises as a business trust under the laws of the
State of Delaware (unless it becomes, or any successor Issuer hereunder is or
becomes, organized under the laws of any other state or of the United States, in
which case the Issuer will keep in full effect its existence, rights and
franchises under the laws of such other jurisdiction) and will obtain and
preserve its qualification to do business in each jurisdiction in which such
qualification is or shall be necessary to protect the validity and
enforceability of this Indenture, the Notes, and the Collateral.

                  Section 3.05 Protection of Trust Estate. The Issuer intends
the security interest Granted pursuant to this Indenture in favor of the
Indenture Trustee on behalf of the Noteholders to be prior to all other liens in
respect of the Collateral, and the Issuer shall take all actions necessary to
obtain and maintain, for the benefit of the Indenture Trustee on behalf of the
Noteholders, a first lien on and a first priority, perfected security interest
in the Collateral. The Issuer will from time to time execute and deliver all
such supplements and amendments hereto and all such financing statements,
continuation statements, instruments of further assurance and other instruments,
all as prepared by the Servicer and delivered to the Issuer, and will take such
other action necessary or advisable to:

                           (i) Grant more effectively all or any portion of the
                  Collateral;



                                      -16-
<PAGE>   22

                           (ii) maintain or preserve the lien and security
                  interest (and the priority thereof) created by this Indenture
                  or carry out more effectively the purposes hereof;

                           (iii) perfect, publish notice of or protect the
                  validity of any Grant made or to be made by this Indenture;

                           (iv) enforce any of the Collateral;

                           (v) preserve and defend title to the Collateral and
                  the rights of the Indenture Trustee and the Noteholders in
                  such Collateral against the claims of all persons and parties;
                  or

                           (vi) pay all taxes or assessments levied or assessed
                  upon the Collateral when due.

The Issuer hereby designates the Indenture Trustee its agent and
attorney-in-fact to execute all financing statements, continuation statements or
other instruments required to be executed pursuant to this Section and the
Indenture Trustee shall execute all financing statements, continuation
statements or other instruments required to be executed pursuant to this section
upon written notice and instructions from the Issuer.

                  Section  3.06   Opinions as to Collateral.

                  (a) Promptly after the execution and delivery of this
Indenture, the Issuer shall furnish to the Indenture Trustee and the Insurer an
Opinion of Counsel to the effect that, in the opinion of such counsel, either
(i) all financing statements and continuation statements have been executed and
filed that are necessary to create and continue the Indenture Trustee's first
priority perfected security interest in the Collateral (subject to the rights of
the Insurer under the Insurance Agreement) for the benefit of the Noteholders,
and reciting the details of such filings or referring to prior Opinions of
Counsel in which such details are given, or (ii) no such action shall be
necessary to perfect such security interest.

                  (b) Within 90 days after the beginning of each calendar year
beginning with the first calendar year beginning more than three months after
the Closing Date, the Issuer shall furnish to the Indenture Trustee and the
Insurer an Opinion of Counsel, dated as of a date during such 90-day period, to
the effect that, in the opinion of such counsel, either (i) all financing
statements and continuation statements have been executed and filed that are
necessary to create and continue the Indenture Trustee's first priority
perfected security interest in the collateral (subject to the rights of the
Insurer under the Insurance Agreement) for the benefit of the Noteholders, and
reciting the details of such filings or referring to prior Opinions of Counsel
in which such details are given, or (ii) no such action shall be necessary to
perfect such security interest.

                  Section 3.07 Performance of Obligations; Servicing of
Contracts.

                  (a) The Issuer will not take any action and will use its best
efforts not to permit any action to be taken by others that would release any
Person from any of such Person's material covenants or obligations under any
instrument or agreement included in the Collateral or that would result in the
amendment, hypothecation, subordination, termination or discharge of, or impair
the



                                      -17-
<PAGE>   23

validity or effectiveness of, any such instrument or agreement, except as
expressly provided in the Basic Documents or such other instrument or agreement.

                  (b) The Issuer may contract with or otherwise obtain the
assistance of other Persons (including, without limitation, the Administrator
under the Administration Agreement) to assist it in performing its duties and
obligations under this Indenture, and any performance of such duties by a Person
identified to the Indenture Trustee and the Insurer in an Officer's Certificate
shall be deemed to be action taken by the Issuer. The Indenture Trustee shall
not be responsible for the action or inaction of the Servicer or the
Administrator. Initially, the Issuer has contracted with the Servicer and the
Administrator to assist the Issuer in performing its duties under this
Indenture.

                  (c) The Issuer will punctually perform and observe all of its
obligations and agreements contained in this Indenture, the other Basic
Documents and in the instruments and agreements included in the Collateral,
including but not limited to filing or causing to be filed all UCC financing
statements and continuation statements required to be filed by the terms of this
Indenture and the Sale and Servicing Agreement in accordance with and within the
time periods provided for herein and therein. Except as otherwise expressly
provided therein, the Issuer shall not waive, amend, modify, supplement or
terminate any Basic Document or any provision thereof without the consent of the
Indenture Trustee, the Insurer (unless an Insurer Default shall have occurred
and be continuing) and the Holders of at least a majority of the Outstanding
Amount of the Notes.

                  (d) If the Issuer shall have actual knowledge of the
occurrence of a Servicer Default, the Issuer shall promptly notify the Indenture
Trustee, the Insurer and each Rating Agency thereof, and shall specify in such
notice the action, if any, the Issuer is taking with respect of such default. If
a Servicer Default shall arise from the failure of the Servicer to perform any
of its duties or obligations under the Sale and Servicing Agreement with respect
to the Contracts, the Issuer shall take all reasonable steps available to it to
remedy such failure.

                  (e) Upon the termination of the Servicer by the Insurer
pursuant to Section 7.01 of the Sale and Servicing Agreement or upon the
resignation of the Servicer pursuant to Section 6.04 of the Sale and Servicing
Agreement, the Insurer shall appoint a successor servicer ("SUCCESSOR
SERVICER"). Upon the termination of the Servicer by the Indenture Trustee, the
Noteholders or the Certificateholders pursuant to Section 7.01 of the Sale and
Servicing Agreement, (i) if the Notes have not been paid in full, the Indenture
Trustee shall be the Successor Servicer, and (ii) if the Notes have been paid in
full, the Owner Trustee, acting at the direction of the Holders of Certificates
evidencing not less than 51% of the outstanding principal amount of the
Certificates, shall appoint a Successor Servicer. The Successor Servicer shall
succeed to all the responsibilities, duties and liabilities of the Servicer
under the Sale and Servicing Agreement. Notwithstanding the foregoing, if the
Notes have not been paid in full, the Indenture Trustee may, if it shall be
unwilling to act, or shall, if it shall be legally unable to so act, appoint, or
petition a court of competent jurisdiction (with any related costs to be at the
sole expense of the Issuer) to appoint, any established financial institution,
having a net worth of not less than $50,000,000 and whose regular business shall
include the servicing of automotive retail installment sales contracts, as the
successor to the Servicer under the Sale and Servicing Agreement. If the
Indenture Trustee shall succeed to the Servicer's duties as servicer of the
Contracts as provided herein, it shall do so in its individual capacity and not
in its capacity as Indenture Trustee and, accordingly, the provisions of Article
Six shall be inapplicable to the Indenture Trustee in its duties as the
successor to the Servicer and the servicing of the



                                      -18-

Contracts. In case the Indenture Trustee shall become successor to the Servicer
under the Sale and Servicing Agreement, the Indenture Trustee shall be entitled
to appoint as Servicer one of its Affiliates, provided that it shall not be
liable for the actions and omissions of any such Affiliate in such capacity as
Successor Servicer appointed with due care.

                  (f) Upon any termination of the Servicer's rights and powers
pursuant to the Sale and Servicing Agreement, the Issuer shall promptly notify
the Indenture Trustee and the Insurer. As soon as a Successor Servicer is
appointed, the Issuer shall notify the Indenture Trustee and the Insurer of such
appointment, specifying in such notice the name and address of such Successor
Servicer.

                  (g) The Issuer agrees that it will not waive timely
performance or observance by the Servicer or the Seller of their respective
duties under the Basic Documents: (i) without the prior consent of the Insurer
(unless an Insurer Default shall have occurred and be continuing) or (ii) if the
effect thereof would adversely affect the Holders of the Notes.

                  Section 3.08 Negative Covenants. Until the Termination Date,
the Issuer shall not:

                           (i) except as expressly permitted by the Basic
                  Documents, sell, transfer, exchange or otherwise dispose of
                  any of the properties or assets of the Issuer, including those
                  included in the Collateral, unless directed to do so by the
                  Indenture Trustee with the prior written consent of the
                  Insurer;

                           (ii) claim any credit on, or make any deduction from
                  the principal or interest payable in respect of, the Notes
                  (other than amounts properly withheld from such payments under
                  the Code or applicable state law) or assert any claim against
                  any present or former Noteholder by reason of the payment of
                  the taxes levied or assessed upon any part of the Collateral;

                           (iii) (A) permit the validity or effectiveness of
                  this Indenture to be impaired, or permit the lien created by
                  this Indenture to be amended, hypothecated, subordinated,
                  terminated or discharged, or permit any Person to be released
                  from any covenants or obligations with respect to the Notes
                  under this Indenture except as may be expressly permitted
                  hereby, (B) permit any lien, charge, excise, claim, security
                  interest, mortgage or other encumbrance (other than the lien
                  of this Indenture) to be created on or extend to or otherwise
                  arise upon or burden the Collateral or any part thereof or any
                  interest therein or the proceeds thereof (other than tax
                  liens, mechanics' liens and other liens that arise by
                  operation of law, in each case on a Financed Vehicle and
                  arising solely as a result of an action or omission of the
                  related Obligor), (C) permit the lien created by this
                  Indenture not to constitute a valid first priority (other than
                  with respect to any such tax, mechanics' or other lien)
                  security interest in the Collateral; or

                           (iv) dissolve or liquidate in whole or in part.

                  made under such Authorized Officer's supervision; and

                           (ii) to the best of such Authorized Officer's

                  all conditions and covenants under this Indenture throughout
                  such year, or, if there has been a default in the compliance
                  of any such condition or covenant, specifying each such
                  default known to such Authorized Officer and the nature and

                                            in the name, and at the expense, of

                           EVENTS OF DEFAULT; REMEDIES

                  Section 5.01 Events of Default. "EVENT OF DEFAULT," wherever
used herein, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):

                  (a) the delivery to the Insurer of a claim for payment under
the Policy;

                  (b) default in the payment of any interest on any Note when
the same becomes due and payable, and such default shall continue for a period
of five days;

                  (c) default in the payment of any principal due and payable on
a Class of Notes on the Final Scheduled Distribution Date for such Class of
Notes;

                  (d) (i) default in the observance or performance of any
covenant or agreement of the Issuer made in this Indenture (other than a
covenant or agreement, a default in the observance or performance of which is
elsewhere in this Section specifically dealt with), and such default shall
continue or not be cured for a period of 90 days after notice thereof shall have
been given, by registered or certified mail, to the Issuer by the Indenture
Trustee or the Insurer or to the Issuer and the Indenture Trustee by the Holders
of at least 25% of the Outstanding Amount of the Notes, acting together as a
single Class or (ii) any representation or warranty made by the Issuer in this
Indenture or in any certificate delivered pursuant hereto or in connection
herewith having been incorrect in a material respect as of the time made, and
such breach not having been cured within 30 days after notice thereof is given
to the Issuer by the Indenture Trustee or the Insurer, or to the Issuer and the
Indenture Trustee by the Holders of at least 25% of the Outstanding Amount of
the Notes acting together as a single Class;

                  (e) the filing of a decree or order for relief by a court
having jurisdiction in the premises in respect of the Issuer or any substantial
part of the Collateral in an involuntary case under any applicable federal or
state bankruptcy, insolvency or other similar law now or hereafter in effect, or
appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator or
similar official of the Issuer or for any substantial part of the Collateral, or
ordering the winding-up or liquidation of the Issuer's affairs, and such decree
or order shall remain unstayed and in effect for a period of 60 consecutive
days; or

<PAGE>   31



                  (f) the commencement by the Issuer of a voluntary case under
any applicable federal or state bankruptcy, insolvency or other similar law now
or hereafter in effect, or the consent by the Issuer to the entry of an order
for relief in an involuntary case under any such law, or the consent by the
Issuer to the appointment or taking possession by a receiver, liquidator,
assignee, custodian, trustee, sequestrator or similar official of the Issuer or
for any substantial part of the Collateral, or the making by the Issuer of any
general assignment for the benefit of creditors, or the failure by the Issuer
generally to pay its debts as such debts become due, or the taking of action by
the Issuer in furtherance of any of the foregoing;

provided, however that so long as no Insurer Default shall have occurred and be
continuing, neither the Indenture Trustee nor the Noteholders may declare an
Indenture Event of Default under the Indenture. So long as an Insurer Default
shall not have occurred and be continuing, an Indenture Event of Default shall
occur only upon delivery by the Insurer to the Indenture Trustee of notice of
the occurrence of an Indenture Event of Default. The failure to pay principal on
a Class of Notes shall not result in the occurrence of an Indenture Event of
Default until the Final Scheduled Distribution Date for such Class of Notes.

         The Issuer shall deliver to the Indenture Trustee and the Insurer,
within five days after obtaining knowledge of the occurrence thereof, written
notice in the form of an Officer's Certificate of any event which with the
giving of notice or the lapse of time would become an Event of Default, its
status and what action the Issuer is taking or proposes to take with respect
thereto.

                  Section 5.02 Rights Upon Event of Default.

                  (a) So long as no Insurer Default has occurred and is
continuing, if an Event of Default shall have occurred and be continuing, then
the Insurer shall have the right, but not the obligation, upon prior written
notice to each Rating Agency, to declare by written notice to the Issuer and the
Indenture Trustee that the Notes become immediately due and payable, and upon
any such declaration the unpaid principal amount of the Notes, together with
accrued and unpaid interest thereon, shall become immediately due and payable.
The Indenture Trustee will have no discretion with respect to the acceleration
of the Notes under the foregoing circumstances. In the event of any such
acceleration of the Notes, the Indenture Trustee shall continue to make claims
under the Policy with respect to the Notes and the Certificates.

                  (b) If an Insurer Default shall have occurred and be
continuing and an Event of Default shall have occurred and be continuing, the
Indenture Trustee shall, if so requested in writing by the Holders of Notes
representing at least 66 2/3% of the aggregate Outstanding Amount of the Notes,
upon prior written notice to each Rating Agency, declare that all the Notes
become immediately due and payable, and upon any such declaration the unpaid
principal amount of the Notes, together with accrued and unpaid interest
thereon, shall become immediately due and payable.

                  (c) Following any Event of Default, the Insurer may elect to
pay all or any portion of the outstanding amount of the Notes, plus accrued
interest thereon to the date of payment.

                  Section 5.03 Collection of Indebtedness and Suits for
Enforcement by Indenture Trustee.

<PAGE>   32



                  (a) The Issuer covenants that, if the Notes are accelerated
following the occurrence of an Event of Default, the Issuer will, upon demand of
the Indenture Trustee, pay to the Indenture Trustee, for the benefit of the
Holders of the Notes, the whole amount then due and payable on such Notes for
principal and interest, with interest upon the overdue principal, and, to the
extent payment at such rate of interest shall be legally enforceable, upon
overdue installments of interest, at the applicable Interest Rate and in
addition thereto such further amount as shall be sufficient to cover the costs
and expenses of collection, including the reasonable compensation, expenses and
disbursements of the Indenture Trustee and its agents and counsel.

                  (b) If an Event of Default shall have occurred and be
continuing, the Indenture Trustee shall (i) if no Insurer Default shall have
occurred and be continuing, at the direction of the Insurer, or (ii) if an
Insurer Default shall have occurred and be continuing, at the direction of the
Holders of Notes representing at least 66 2/3% of the Outstanding Amount of the
Notes, as more particularly provided in Section 5.04, proceed to protect and
enforce the rights of the Noteholders, by such appropriate Proceedings as the
Indenture Trustee shall deem most effective to protect and enforce any such
rights, whether for the specific enforcement of any covenant or agreement in
this Indenture or in aid of the exercise of any power granted herein, or to
enforce any other proper remedy or legal or equitable right vested in the
Indenture Trustee by this Indenture or by law.

                  (c) In case there shall be pending, relative to the Issuer or
any other obligor upon the Notes or any Person having or claiming an ownership
interest in the Collateral, Proceedings under Title 11 of the United States Code
or any other applicable federal or state bankruptcy, insolvency or other similar
law, or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, sequestrator or similar official shall have been appointed for or
taken possession of the Issuer or its property or such other obligor or Person,
or in case of any other comparable judicial Proceedings relative to the Issuer
or other obligor upon the Notes, or to the creditors or property of the Issuer
or such other obligor, the Indenture Trustee, irrespective of whether the
principal of any Notes shall then be due and payable as therein expressed or by
declaration or otherwise and irrespective of whether the Indenture Trustee shall
have made any demand pursuant to the provisions of this Section, shall be
entitled and empowered, by intervention in such Proceedings or otherwise:

                           (i) to file and prove a claim or claims for the whole
                  amount of principal and interest owing and unpaid in respect
                  of the Notes and to file such other papers or documents as may
                  be necessary or advisable in order to have the claims of the
                  Indenture Trustee (including any claim for reasonable
                  compensation to the Indenture Trustee and each predecessor
                  Indenture Trustee, and their respective agents, attorneys and
                  counsel, and for reimbursement of all expenses and liabilities
                  incurred by the Indenture Trustee and each predecessor
                  Indenture Trustee, except as a result of negligence or bad
                  faith) and of the Noteholders allowed in such Proceedings;

                           (ii) unless prohibited by applicable law and
                  regulations, to vote on behalf of the Holders of Notes in any
                  election of a trustee, a standby trustee or Person performing
                  similar functions in any such Proceedings;

                           (iii) to collect and receive any monies or other
                  property payable or deliverable on any such claims and to
                  distribute all amounts received with respect to the claims of
                  the Noteholders and of the Indenture Trustee on their behalf;
                  and



                                      -27-

                           (iv) to file such proofs of claim and other papers or
                  documents as may be necessary or advisable in order to have
                  the claims of the Indenture Trustee or the Holders of Notes
                  allowed in any judicial proceedings relative to the Issuer,
                  its creditors and its property;

and any trustee, receiver, liquidator, custodian or other similar official in
any such Proceeding is hereby authorized by each of such Noteholders to make
payments to the Indenture Trustee, and, in the event that the Indenture Trustee
shall consent to the making of payments directly to such Noteholders, to pay to
the Indenture Trustee such amounts as shall be sufficient to cover reasonable
compensation to the Indenture Trustee, each predecessor Indenture Trustee and
their respective agents, attorneys and counsel, and all other expenses and
liabilities incurred by the Indenture Trustee and each predecessor Indenture
Trustee except as a result of negligence or bad faith.

                  (d) Nothing herein contained shall be deemed to authorize the
Indenture Trustee to authorize or consent to or vote for or accept or adopt on
behalf of any Noteholder any plan of reorganization, arrangement, adjustment or
composition affecting the Notes or the rights of any Holder thereof or to
authorize the Indenture Trustee to vote in respect of the claim of any
Noteholder in any such proceeding except, as aforesaid, to vote for the election
of a trustee in bankruptcy or similar Person.

                  (e) All rights of action and of asserting claims under this
Indenture, or under any of the Notes, may be enforced by the Indenture Trustee
without the possession of any of the Notes or the production thereof in any
trial or other Proceedings relative thereto, and any such action or Proceedings
instituted by the Indenture Trustee shall be brought in its own name as trustee
of an express trust, and any recovery of judgment, subject to the payment of the
expenses, disbursements and compensation of the Indenture Trustee, each
predecessor Indenture Trustee and their respective agents and attorneys, shall
be for the ratable benefit of the Holders of the Notes.

                  (f) In any Proceedings brought by the Indenture Trustee
(including any Proceedings involving the interpretation of any provision of this
Indenture), the Indenture Trustee shall be held to represent all the
Noteholders, and it shall not be necessary to make any Noteholder a party to any
such Proceedings.

                  Section 5.04 Remedies.

                  (a) If (i) an Event of Default shall have occurred and be
continuing, the Indenture Trustee shall (subject to Section 5.04(b) below and
Section 5.05), if no Insurer Default shall have occurred and be continuing, at
the direction of the Insurer, or (ii) if an Event of Default shall have occurred
and be continuing, the Indenture Trustee shall (subject to Section 5.04(b) below
and Section 5.05), if an Insurer Default shall have occurred and be continuing,
at the direction of the Holders of Notes representing at least 66 2/3% of the
Outstanding Amount of the Notes, take one or more of the following actions as so
directed:

                           (i) institute Proceedings in its own name and as or
                  on behalf of a trustee of an express trust for the collection
                  of all amounts then payable on the Notes or under this
                  Indenture with respect thereto, whether by declaration or
                  otherwise, enforce any judgment obtained, and collect from the
                  Issuer and any other obligor upon such Notes monies adjudged

                  complete or partial foreclosure of this Indenture with respect
                  to the Collateral;

                           (iii) exercise any remedies of a secured party under
                  the UCC and any other remedy available to the Indenture
                  Trustee and take any other appropriate action to protect and
                  enforce the rights and remedies of the Indenture Trustee on
                  behalf of the Noteholders under this Indenture or the Notes;

                           (iv) sell or cause the Servicer to otherwise
                  liquidate the Collateral or any portion thereof or rights or
                  interests therein, at one or more public or private sales
                  called and conducted in any manner permitted by law and
                  deliver the proceeds of such sale or liquidation to the
                  Indenture Trustee for distribution in accordance with the
                  terms of this Indenture; and

                           (v) maintain possession of the Collateral.

                  (b) Notwithstanding the foregoing,

                           (i) in the event that the Indenture Trustee is acting
                  at the direction of the Insurer, so long as an Insurer Default
                  shall not have occurred and be continuing, if an Event of
                  Default shall have occurred and be continuing, the Insurer
                  shall not have the right to cause the Indenture Trustee or the
                  Servicer to, and neither the Indenture Trustee nor the
                  Servicer shall, liquidate the Collateral in whole or in part
                  if the proceeds of such sale or liquidation would not be
                  sufficient to pay all outstanding principal of and accrued
                  interest on the Notes; and

                           (ii) in the event that the Indenture Trustee is
                  acting at the direction of the Holders of Notes representing
                  at least 66 2/3% of the Outstanding Amount of the Notes, the
                  Noteholders shall not have the right to direct the Indenture
                  Trustee or the Servicer to, and neither the Indenture Trustee
                  nor the Servicer shall, liquidate the Collateral in whole or
                  in part unless (A) an Indenture Event of Default as specified
                  in Section 5.01(b), (c), (e) or (f) shall have occurred and be
                  continuing and in any case the Insurer shall have failed to
                  make a payment required under the Policy in accordance with
                  its terms or (B) (1) an Indenture Event of Default as
                  specified in Section 5.01(a) or (d) shall have occurred and be
                  continuing, (2) the Insurer shall not have failed to make a
                  payment required under the Policy in accordance with its terms
                  and (3) either (x) the proceeds of such sale or liquidation
                  would be sufficient to pay all outstanding principal of and
                  accrued interest on the Notes and the Certificates and all
                  amounts owing to the Insurer pursuant to the terms of the
                  Insurance Agreement or (y) the Holders of Certificates
                  evidencing 100% of the outstanding principal amount of the
                  Certificates consent to such liquidation and all amounts owing
                  to the Insurer under the Insurance Agreement shall be paid
                  upon such sale or liquidation. In the event of a liquidation
                  of the Collateral pursuant to clause (B), the Policy will not
                  be available to cover losses to Securityholders resulting from
                  such liquidation, and the Policy shall be terminated and the
                  Insurer shall have no further obligation thereunder.

                  (c) In determining the sufficiency or insufficiency of the
proceeds of a sale or liquidation of the Collateral to pay all amounts required
pursuant to Section 5.04(b)(i) or (ii) above, the Indenture Trustee may, but
need not, at the sole expense of the Issuer obtain and rely upon an opinion of
an Independent investment banking or accounting firm of national reputation as
to the feasibility of such proposed action and as to the sufficiency of the
Collateral for such purpose.

                  (d) In the event that the Indenture Trustee is directed to
sell or to cause the Servicer to otherwise liquidate the Collateral or any
portion thereof or rights or interests therein pursuant to Section 5.04(a)(iv)
above, the Indenture Trustee shall, prior to any such public or private sales,
notify all Residual Interestholders of the proposed sale. The Indenture Trustee
shall provide the Residual Interestholders the right to match the highest
liquidation price offered at any such sale.

                  Section 5.05 Optional Preservation of the Contracts. If the
Notes have been declared to be due and payable under Section 5.02 following an
Event of Default and such declaration and its consequences have not been
rescinded and annulled, the Indenture Trustee shall, absent direction to the
contrary from the Insurer or the Noteholders pursuant to Section 5.04, maintain
possession of the Collateral.

                  Section 5.06 Priorities.

                  (a) If the Notes have been declared to be due and payable
under Section 5.02 following an Indenture Event of Default and such declaration
and its consequences have not been rescinded and annulled, any money collected
by the Indenture Trustee with respect to the Collateral, the Notes or the
Certificates pursuant to this Article or otherwise and any money that may then
be held or thereafter received by the Indenture Trustee with respect to the
Collateral, the Notes or the Certificates (excluding any payments made under the
Policy), shall be applied in the following order and priority:

                           first, to the Servicer, to pay any unpaid Servicing
                  Fee;

                           second, to pay any accrued and unpaid fees and
                  expenses of the Owner Trustee, the Indenture Trustee and the
                  Trust Agent without preference or priority of any kind;

                           third, to the Noteholders, to pay accrued interest on
                  each Class of Notes on a pro rata basis based on the interest
                  accrued (including, to the extent permitted by applicable law,
                  interest accrued on any interest accrued but not timely paid)
                  on each Class of Notes at the related Interest Rate for such
                  Class;

                           fourth, to the Noteholders, to pay principal on each
                  Class of Notes on a pro rata basis based on the Outstanding
                  Amount of each Class of Notes, until the Outstanding Amount of
                  each Class of Notes is reduced to zero;

                           fifth, to the Certificateholders, to pay accrued
                  interest on the Certificates (including, to the extent
                  permitted by applicable law, interest accrued on any interest
                  accrued but not timely paid) at the Certificate Rate;



                                      -30-
<PAGE>   36

                           sixth, to the Certificateholders, to pay principal on
                  the Certificates until the Certificate Balance is reduced to
                  zero;

                           seventh, to the Insurer, to pay amounts owing to the
                  Insurer under the Insurance Agreement (including the Premium);
                  and

                           eighth, any excess amounts remaining after making the
                  distributions described in clauses first through seventh to
                  the Spread Account, to be applied in accordance with the
                  Insurance Agreement.

                  (b) The Indenture Trustee may fix a record date and payment
date for any payment to Noteholders pursuant to this Section. At least 15 days
before such record date, the Issuer shall mail to each Noteholder and the
Indenture Trustee a notice that states the record date, the payment date and the
amount to be paid.

                  Section 5.07 Limitation of Suits. No Holder of any Note shall
have any right to institute any Proceeding, judicial or otherwise, with respect
to this Indenture, or for the appointment of a receiver or trustee, or for any
other remedy hereunder, unless:

                           (i) such Holder has previously given written notice
                  to the Indenture Trustee of a continuing Event of Default;

                           (ii) the Holders of not less than 25% of the
                  Outstanding Amount of the Notes have made written request to
                  the Indenture Trustee to institute such Proceeding in respect
                  of such Event of Default in its own name as Indenture Trustee
                  hereunder;

                           (iii) such Holder or Holders have offered to the
                  Indenture Trustee reasonable indemnity against the costs,
                  expenses and liabilities to be incurred in complying with such
                  request;

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

                           (v) no direction inconsistent with such written
                  request has been given to the Indenture Trustee during such
                  60-day period by the Holders of a majority of the Outstanding
                  Amount of the Notes, voting together as a single Class; and

                           (vi) an Insurer Default shall have occurred and be
                  continuing.

It is understood and intended that no one or more Holders of Notes shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other
Holders of Notes or to obtain or to seek to obtain priority or preference over
any other Holders or to enforce any right under this Indenture, except in the
manner herein provided.

         In the event the Indenture Trustee shall receive conflicting or
inconsistent requests and indemnity from two or more groups of Holders of Notes,
each representing less than a majority of the Outstanding Amount of the Notes,
the Indenture Trustee shall act at the request of the Holders



                                      -31-
<PAGE>   37

of the Notes with the greater Outstanding Amount of Notes; provided, however
that if such groups of Holders of Notes have the same Outstanding Amount of
Notes, the Indenture Trustee in its sole discretion may determine what action,
if any, shall be taken, notwithstanding any other provisions of this Indenture
and any such action shall be binding on all parties.

                  Section 5.08 Unconditional Rights of Noteholders to Receive
Principal and Interest. Notwithstanding any other provisions in this Indenture,
the Holder of any Note shall have the right, which is absolute and
unconditional, to receive payment of the principal of and interest on such Note
on or after the respective due dates thereof expressed in such Note or in this
Indenture (or, in the case of redemption of the Notes, on or after the
Redemption Date) and to institute suit for the enforcement of any such payment,
and such right shall not be impaired without the consent of such Holder.

                  Section 5.09 Restoration of Rights and Remedies. If the
Indenture Trustee, the Insurer or any Noteholder has instituted any Proceeding
to enforce any right or remedy under this Indenture and such Proceeding has been
discontinued or abandoned for any reason or has been determined adversely to the
Indenture Trustee, the Insurer or to such Noteholder, then and in every such
case the Issuer, the Indenture Trustee, the Insurer and the Noteholders shall,
subject to any determination in such Proceeding, be restored severally and
respectively to their former positions hereunder, and thereafter all rights and
remedies of the Indenture Trustee and the Noteholders shall continue as though
no such Proceeding had been instituted.

                  Section 5.10 Rights and Remedies Cumulative. No right or
remedy herein conferred upon or reserved to the Indenture Trustee, the Insurer
or to the Noteholders is intended to be exclusive of any other right or remedy,
and every right and remedy shall, to the extent permitted by law, be cumulative
and in addition to every other right and remedy given hereunder or now or
hereafter existing at law or in equity or otherwise. The assertion or employment
of any right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

                  Section 5.11 Delay or Omission Not a Waiver. No delay or
omission of the Indenture Trustee, the Insurer or any Holder of any Note to
exercise any right or remedy accruing upon any Default or Event of Default shall
impair any such right or remedy or constitute a waiver of any such Default or
Event of Default or an acquiescence therein. Every right and remedy given by
this Article Five or by law to the Indenture Trustee, the Insurer or to the
Noteholders may be exercised from time to time, and as often as may be deemed
expedient, by the Indenture Trustee, the Insurer or by the Noteholders, as the
case may be.

                  Section 5.12 Control by Noteholders. The Holders of a majority
of the Outstanding Amount of the Notes shall have the right to direct the time,
method and place of conducting any Proceeding for any remedy available to the
Indenture Trustee with respect to the Notes or exercising any trust or power
conferred on the Indenture Trustee; provided that:

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

                           (ii) any direction to the Indenture Trustee to sell
                  or liquidate the Collateral shall be subject to the terms of
                  Section 5.04; and



                                      -32-
<PAGE>   38

                           (iii) the Indenture Trustee may take any other action
                  deemed proper by the Indenture Trustee that is not
                  inconsistent with such direction.

Notwithstanding the rights of Noteholders set forth in this Section, subject to
Section 6.01, the Indenture Trustee need not take any action that it determines,
in its sole discretion, might involve it in liability or might materially
adversely affect the rights of any Noteholders not consenting to such action.

                  Section 5.13 Waiver of Past Defaults. Prior to the declaration
of the acceleration of the maturity of the Notes as provided in Section 5.02,
the Insurer or the Holders of Notes representing not less than a majority of the
Outstanding Amount of the Notes with the consent of the Insurer may waive any
past Default or Event of Default and its consequences except a Default (a) in
the payment of or interest on any of the Notes or (b) in respect of a covenant
or provision hereof that cannot be modified or amended without the consent of
the Holder of each Note, as applicable. In the case of any such waiver, the
Issuer, the Indenture Trustee, the Insurer and the Holders of the Notes shall be
restored to their former positions and rights hereunder, respectively; but no
such waiver shall extend to any subsequent or other Default or impair any right
consequent thereto.

         Upon any such waiver, such Default shall cease to exist and be deemed
to have been cured and not to have occurred, and any Event of Default arising
therefrom shall be deemed to have been cured and not to have occurred, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other Default or Event of Default or impair any right consequent thereto.

                  Section 5.14 Undertaking for Costs. All parties to this
Indenture agree, and each Holder of any Note by such Holder's acceptance thereof
shall be deemed to have agreed, that any court may in its discretion require, in
any suit for the enforcement of any right or remedy under this Indenture, or in
any suit against the Indenture Trustee for any action taken, suffered or omitted
by it as Indenture Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to (i) any suit instituted by the
Indenture Trustee, (ii) any suit instituted by any Noteholder, or group of
Noteholders, in each case holding in the aggregate more than 10% of the
Outstanding Amount of the Notes or (iii) any suit instituted by any Noteholder
for the enforcement of the payment of principal of or interest on any Note on or
after the respective due dates expressed in such Note and in this Indenture (or,
in the case of redemption, on or after the Redemption Date).

                  Section 5.15 Waiver of Stay or Extension Laws. The Issuer
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead or in and manner whatsoever, claim or take the
benefit or advantage of, any stay or extension law wherever enacted, now or at
any time hereafter in force, that may affect the covenants or the performance of
this Indenture; and the Issuer (to the extent that it may lawfully do so) hereby
expressly waives all benefit or advantages of any such law, and covenants that
it will not hinder, delay or impede the execution of any power herein granted to
the Indenture Trustee, but will suffer and permit the execution of every such
power as though no such law had been enacted.

                  Section 5.16 Action on Notes. The Indenture Trustee's right to
seek and recover judgment on the Notes or under this Indenture shall not be
affected by the seeking, obtaining or



                                      -33-
<PAGE>   39

application of any other relief under or with respect to this Indenture. Neither
the lien of this Indenture nor any rights or remedies of the Indenture Trustee
or the Noteholders shall be impaired by the recovery of any judgment by the
Indenture Trustee against the Issuer or by the levy of any execution under such
judgment upon any portion of the Collateral or upon any of the assets of the
Issuer. Any money or property collected by the Indenture Trustee shall be
applied in accordance with Section 5.06.

                  Section 5.17 Performance and Enforcement of Certain
Obligations.

                  (a) Promptly following a request from the Indenture Trustee to
do so and at the Administrator's expense, the Issuer shall take all such lawful
action as the Indenture Trustee may request to compel or secure the performance
and observance by the Seller and the Servicer as applicable, of each of their
obligations to the Issuer under or in connection with the Sale and Servicing
Agreement in accordance with the terms thereof, and to exercise any and all
rights, remedies, powers and privileges lawfully available to the Issuer under
or in connection with the Sale and Servicing Agreement to the extent and in the
manner directed by the Indenture Trustee, including the transmission of notices
of default on the part of the Seller or the Servicer thereunder and the
institution of legal or administrative actions or proceedings to compel or
secure performance by the Seller or the Servicer of each of their obligations
under the Sale and Servicing Agreement.

                  (b) If the Indenture Trustee is the Controlling Party and if
an Event of Default has occurred and is continuing, the Indenture Trustee may,
and at the direction (which direction shall be given in writing and may include
a facsimile) of the Holders of 66 2/3% of the Outstanding Amount of the Notes
shall, exercise all rights, remedies, powers, privileges and claims of the
Issuer against the Seller or the Servicer under or in connection with the Sale
and Servicing Agreement, including the right or power to take any action to
compel or secure performance or observance by the Seller or the Servicer of each
of their obligations to the Issuer thereunder and to give any consent, request,
notice, direction, approval, extension or waiver under the Sale and Servicing
Agreement, and any right of the Issuer to take such action shall be suspended.

                                   ARTICLE VI

                              THE INDENTURE TRUSTEE

                  Section 6.01 Duties of Indenture Trustee.

                  (a) If an Event of Default has occurred and is continuing, and
of which the Indenture Trustee shall have actual knowledge, the Indenture
Trustee shall exercise the rights and powers vested in it by this Indenture and
with the same degree of care and skill in their exercise as a prudent person
would exercise or use under the circumstances in the conduct of such person's
own affairs; provided, however, that if the Indenture Trustee shall assume the
duties of the Servicer pursuant to Section 3.07(e), the Indenture Trustee in
performing such duties shall use the degree of care and skill customarily
exercised by a prudent institutional servicer with respect to automobile retail
installment sales contracts that it services for itself or others.

                  (b) Except during the continuance of an Event of Default of
which a Responsible Officer of the Indenture Trustee shall have actual knowledge
or written notice:



                                      -34-
<PAGE>   40

                           (i) the Indenture Trustee undertakes to perform such
                  duties and only such duties as are specifically set forth in
                  this Indenture and no implied covenants or obligations shall
                  be read into this Indenture against the Indenture Trustee; and

                           (ii) in the absence of bad faith on its part, the
                  Indenture Trustee may conclusively rely, as to the truth of
                  the statements and the correctness of the opinions expressed
                  therein, upon certificates or opinions furnished to the
                  Indenture Trustee and conforming to the requirements of this
                  Indenture; however, the Indenture Trustee shall examine the
                  certificates and opinions to determine whether or not they
                  conform to the requirements of this Indenture and the other
                  Basic Documents to which the Indenture Trustee is a party;
                  provided, however, that the Indenture Trustee shall not be
                  responsible for the accuracy or content of any of the
                  aforementioned documents and the Indenture Trustee shall have
                  no obligation to verify, re-compute or recalculate any
                  numerical information provided to it pursuant to the Basic
                  Documents.

                  (c) The Indenture Trustee may not be relieved from liability
for its own negligent action, its own negligent failure to act or its own wilful
misconduct, except that:

                           (i) this paragraph does not limit the effect of
                  Section 6.01(b);

                           (ii) the Indenture Trustee shall not be liable for
                  any error of judgment made in good faith by a Responsible
                  Officer unless it is proved that the Indenture Trustee was
                  negligent in ascertaining the pertinent facts; and

                           (iii) the Indenture Trustee shall not be liable with
                  respect to any action it takes or omits to take in good faith
                  in accordance with a direction received by it pursuant to
                  Section 5.12.

                  (d) Every provision of this Indenture that in any way relates
to the Indenture Trustee is subject to paragraphs (a), (b) and (c) of this
Section.

                  (e) The Indenture Trustee shall not be liable for interest on
any money received by it.

                  (f) Money held in trust by the Indenture Trustee need not be
segregated from other funds except to the extent required by law or the terms of
this Indenture or the Sale and Servicing Agreement.

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

                  (h) Every provision of this Indenture relating to the conduct
or affecting the liability of or affording protection to the Indenture Trustee
shall be subject to the provisions of this Section and to the provisions of the
TIA.



                                      -35-
<PAGE>   41

                  (i) The Indenture Trustee shall, and hereby agrees that it
will (i) perform all of the obligations and duties required of it under the Sale
and Servicing Agreement and (ii) hold the Policy in trust, and will hold any
proceeds of any claim on the Policy in trust solely for application as provided
in the Sale and Servicing Agreement.

                  (j) Except as otherwise required or permitted by the TIA,
nothing contained herein shall be deemed to authorize the Indenture Trustee to
engage in any business operations or any activities other than those set forth
in this Indenture. Specifically, the Indenture Trustee shall have no authority
to engage in any business operations, acquire any assets other than those
specifically included in the Collateral under this Indenture or otherwise vary
the assets held by the Trust. Similarly, the Indenture Trustee shall have no
discretionary duties other than performing those ministerial acts set forth
above necessary to accomplish the purpose of this Trust as set forth in this
Indenture.

                  (k) The Indenture Trustee shall not be liable in its
individual capacity with respect to any action taken, suffered or omitted to be
taken by it in good faith in accordance with this Indenture or at the direction
of a majority of the Outstanding Amount of Notes, relating to the time, method
and place of conducting any proceeding for any remedy available to the Indenture
Trustee, or exercising or omitting to exercise any trust or power conferred upon
the Indenture Trustee, under this Indenture.

                  (l) The Indenture Trustee shall not be required to take notice
or be deemed to have notice or knowledge of any Default or Event of Default
unless a Responsible Officer of the Indenture Trustee shall have received
written notice thereof. In the absence of receipt of such notice, the Indenture
Trustee may conclusively assume that there is no Default or Event of Default.

                  (m) Subject to the other provisions of this Indenture, the
Indenture Trustee shall have no duty (i) to see to any recording, filing, or
depositing of this Agreement or any agreement referred to herein or any
financing statement or continuation statement evidencing a security interest, or
to see to the maintenance of any such recording or filing or depositing or to
any rerecording, refiling or redepositing of any thereof, (ii) to see to any
insurance, (iii) to see to the payment or discharge of any tax, assessment, or
other governmental charge or any lien or encumbrance of any kind owing with
respect to, assessed or levied against, any part of the Collateral, or (iv) to
confirm or verify the contents of any reports or certificates delivered to the
Indenture Trustee pursuant to this Indenture believed by the Indenture Trustee
to be genuine and to have been signed or presented by the proper party or
parties.

                  (n) Anything in this Agreement to the contrary
notwithstanding, in no event shall the Indenture Trustee be liable for special,
indirect or consequential loss or damage of any kind whatsoever (including but
not limited to lost profits), even if the Indenture Trustee has been advised of
the likelihood of such loss or damage regardless of the form of action.

                  Section 6.02 Rights of Indenture Trustee.

                  (a) Except as otherwise provided in the second succeeding
sentence, the Indenture Trustee may conclusively rely and shall be protected in
acting upon or refraining from acting upon any resolution, certificate,
statement, instrument, opinion, report, notice, request, consent, order, note,
direction, demand, election or other paper or document believed by it to be
genuine and to have



                                      -36-
<PAGE>   42

been signed or presented by the proper person. The Indenture Trustee need not
investigate any fact or matter stated in the document. Notwithstanding the
foregoing, the Indenture Trustee, subject to Section 6.01(b)(ii) upon receipt of
all resolutions, certificates, statements, opinions, reports, documents, orders
or other instruments furnished to the Indenture Trustee that shall be
specifically required to be furnished pursuant to any provision of this
Indenture, shall examine them to determine whether they comply as to form to the
requirements of this Indenture.

                  (b) Before the Indenture Trustee acts or refrains from acting,
it may require an Officer's Certificate (with respect to factual matters) or an
Opinion of Counsel, as applicable. The Indenture Trustee shall not be liable for
any action it takes or omits to take in good faith in reliance on the Officer's
Certificate or Opinion of Counsel.

                  (c) The Indenture Trustee may execute any of the trusts or
powers hereunder or perform any duties hereunder either directly or by or
through agents or attorneys or a custodian or nominee and the Indenture Trustee
shall not be responsible for any misconduct or negligence on the part of any
such agent, attorney, custodian or nominee appointed by the Indenture Trustee
with due care.

                  (d) The Indenture Trustee shall not be liable for any action
it takes or omits to take in good faith which it believes to be authorized or
within its rights or powers; provided, however, that the Indenture Trustee's
conduct does not constitute willful misconduct, negligence or bad faith.

                  (e) The Indenture Trustee may consult with counsel, and the
advice or opinion of counsel with respect to legal matters relating to this
Indenture and the Notes shall be full and complete authorization and protection
from liability in respect to any action taken, omitted or suffered by it
hereunder in good faith and in accordance with the advice or opinion of such
counsel.

                  (f) The Indenture Trustee shall be under no obligation to
exercise any of the trusts or powers vested in it by this Indenture or to
institute, conduct or defend any litigation hereunder or in relation hereto at
the request, order or direction of any of the Noteholders, pursuant to the
provisions of this Indenture, unless such Noteholders shall have offered to the
Indenture Trustee reasonable security or indemnity against the costs, expenses
and liabilities which may be incurred therein or thereby; nothing contained
herein shall, however, relieve the Indenture Trustee of the obligation, during
the continuance of an Event of Default of which a Responsible Officer of the
Indenture Trustee shall have actual knowledge, to exercise such of the rights
and powers vested in it by this Indenture, and to use the same degree of care
and skill in their exercise, as a prudent person would exercise or use under the
circumstances in the conduct of such person's own affairs.

                  (g) The Indenture Trustee shall not be bound to make any
investigation into the facts or matters stated in any resolution, certificate,
statement, instrument, opinion, report, notice, request, consent, order,
approval, bond or other paper or document, unless requested in writing to do so
by a majority of Noteholders; provided, however, that if the payment within a
reasonable time to the Indenture Trustee of the costs, expenses or liabilities
likely to be incurred by it in the making of such investigation is, in the
opinion of the Indenture Trustee, not reasonably assured to the Indenture
Trustee by the security afforded to it by the terms of this Agreement, the
Indenture Trustee may require reasonable indemnity against such cost, expense or
liability as a condition to taking any such action.

                  (h) The right of the Indenture Trustee to perform any
discretionary act enumerated in this Indenture shall not be construed as a duty,
and the Indenture Trustee shall not be answerable for other than its willful
misconduct, negligence or bad faith in the performance of such act.

                  Section 6.03 Individual Rights of Indenture Trustee. The
Indenture Trustee in its individual or any other capacity may become the owner
or pledgee of Notes and may otherwise deal with the Issuer or its Affiliates
with the same rights it would have if it were not Indenture Trustee. Any Paying
Agent, Note Registrar, co-registrar or co-paying agent may do the same with like
rights. However, the Indenture Trustee is required to comply with Sections 6.11
and 6.12.

                  Section 6.04 Indenture Trustee's Disclaimer. The Indenture
Trustee shall not be responsible for and makes no representation as to the
validity or adequacy of this Indenture, the Collateral or the Notes, it shall
not be accountable for the Issuer's use of the proceeds from the Notes, and it
shall not be responsible for any statement of the Issuer in this Indenture or in
any document issued in connection with the sale of the Notes or in the Notes
other than the Indenture Trustee's certificate of authentication.

                  Section 6.05 Notice of Defaults. If a Default occurs and is
continuing and a Responsible Officer of the Indenture Trustee has actual
knowledge or has received written notice thereof, the Indenture Trustee shall
mail to each Noteholder and the Insurer notice of the Default within 90 days
after it occurs. Except in the case of a Default in payment of principal of or
interest on any Note (including payments pursuant to the redemption of Notes),
the Indenture Trustee may withhold the notice if and so long as a committee of
its Responsible Officers in good faith determines that withholding the notice is
in the interests of Noteholders.

                  Section 6.06 Reports by Indenture Trustee to Holders. The
Indenture Trustee shall deliver to each Noteholder such information as may be
required to enable such Holder to prepare its federal and state income tax
returns.

                  Section 6.07 Compensation and Indemnity. The Issuer shall
cause the Servicer to pay to the Indenture Trustee from time to time reasonable
compensation for its services. The Indenture Trustee's compensation shall not be
limited by any law on compensation of a trustee of an express trust. The Issuer
shall cause the Servicer to reimburse the Indenture Trustee for all reasonable
out-of-pocket expenses incurred or made by it, including costs of collection, in
addition to the compensation for its services. Such expenses shall include the
reasonable compensation and expenses and disbursements and advances of the
Indenture Trustee's agents, counsel, accountants and experts. The Issuer shall,
or shall cause the Administrator to, indemnify the Indenture Trustee against any
and all loss, liability or expense (including attorneys' fees) incurred by it in
connection with the administration of this trust and the performance of its
duties hereunder. The Indenture Trustee shall notify the Issuer and the
Administrator promptly of any claim for which it may seek indemnity. Failure by
the Indenture Trustee to so notify the Issuer and the Administrator shall not
relieve the Issuer or the Administrator of its obligations hereunder. The Issuer
shall, or shall cause the Administrator to, defend any such claim, and the
Indenture Trustee may have separate counsel and the Issuer shall, or shall cause
the Administrator to, pay the fees and expenses of such counsel. Neither the
Issuer nor the Administrator need reimburse any expense or indemnify against any
loss, liability or expense incurred by the Indenture Trustee through the
Indenture Trustee's own willful misconduct, negligence or bad faith.



                                      -38-
<PAGE>   44

         The Issuer's obligations to the Indenture Trustee pursuant to this
Section shall survive the resignation or removal of the Indenture Trustee and
the discharge of this Indenture. When the Indenture Trustee incurs expenses
after the occurrence of a Default specified in Section 5.01(e) or (f) with
respect to the Issuer, the expenses are intended to constitute expenses of
administration under Title 11 of the United States Code or any other applicable
federal or state bankruptcy, insolvency or similar law.

                  Section 6.08 Replacement of Indenture Trustee. The Indenture
Trustee may resign at any time by so notifying the Issuer, the Servicer and the
Insurer. The Issuer, may, with the consent of the Insurer, and, at the request
of the Insurer shall, remove the Indenture Trustee, unless an Insurer Default
shall have occurred and be continuing, if:

                           (i) the Indenture Trustee fails to comply with
                  Section 6.11;

                           (ii) a court having jurisdiction in the premises in
                  respect of the Indenture Trustee in an involuntary case or
                  proceeding under federal or state banking or bankruptcy laws,
                  as now or hereafter constituted, or any other applicable
                  federal or state bankruptcy, insolvency or other similar law,
                  shall have entered a decree or order granting relief or
                  appointing a receiver, liquidator, assignee, custodian,
                  trustee, conservator, sequestrator (or similar official) for
                  the Indenture Trustee or for any substantial part of the
                  Indenture Trustee's property, or ordering the winding-up or
                  liquidation of the Indenture Trustee's affairs, provided any
                  such decree or order shall have continued unstayed and in
                  effect for a period of 30 consecutive days;

                           (iii) the Indenture Trustee commences a voluntary
                  case under any federal or state banking or bankruptcy laws, as
                  now or hereafter constituted, or any other applicable federal
                  or state bankruptcy, insolvency or other similar law, or
                  consents to the appointment of or taking possession by a
                  receiver, liquidator, assignee, custodian, trustee,
                  conservator, sequestrator or other similar official for the
                  Indenture Trustee or for any substantial part of the Indenture
                  Trustee's property, or makes any assignment for the benefit of
                  creditors or fails generally to pay its debts as such debts
                  become due or takes any corporate action in furtherance of any
                  of the foregoing; or

                           (iv) the Indenture Trustee otherwise becomes
                  incapable of acting.

         If the Indenture Trustee resigns or is removed or if a vacancy exists
in the office of Indenture Trustee for any reason (the Indenture Trustee in such
event being referred to herein as the retiring Indenture Trustee), the Issuer
shall promptly appoint a successor Indenture Trustee acceptable to the Insurer.

          A successor Indenture Trustee shall deliver a written acceptance of
its appointment to the retiring Indenture Trustee and to the Issuer. Thereupon
the resignation or removal of the retiring Indenture Trustee shall become
effective, and the successor Indenture Trustee shall have all the rights, powers
and duties of the Indenture Trustee under this Indenture. The Issuer or the
successor Indenture Trustee shall mail a notice of its succession to
Noteholders. The retiring Indenture Trustee shall promptly transfer all property
held by it as Indenture Trustee to the successor Indenture Trustee.



                                      -39-
<PAGE>   45

         If a successor Indenture Trustee does not take office within 30 days
after the retiring Indenture Trustee resigns or is removed, the retiring
Indenture Trustee, the Issuer or the Holders of a majority of the Outstanding
Amount of the Notes may petition any court of competent jurisdiction for the
appointment of a successor Indenture Trustee.

         If the Indenture Trustee fails to comply with Section 6.11, any
Noteholder may petition any court of competent jurisdiction for the removal of
the Indenture Trustee and the appointment of a successor Indenture Trustee.

         Any resignation or removal of the Indenture Trustee and appointment of
a successor Indenture Trustee pursuant to the provisions of this Section shall
not become effective until acceptance of appointment by the successor Indenture
Trustee pursuant to this Section and payment of all fees and expenses owed to
the outgoing Indenture Trustee. Notwithstanding the replacement of the Indenture
Trustee pursuant to this Section, the retiring Indenture Trustee shall be
entitled to payment or reimbursement of such amounts as such Person is entitled
pursuant to Section 6.07.

                  Section 6.09 Successor Indenture Trustee by Merger. If the
Indenture Trustee consolidates with, merges or converts into, or transfers all
or substantially all its corporate trust business or assets to, another
corporation or banking association, the resulting, surviving or transferee
corporation without any further act shall be the successor Indenture Trustee;
provided, that such corporation or banking association shall be otherwise
qualified and eligible under Section 6.11. The Indenture Trustee shall (unless
the Indenture Trustee is The Chase Manhattan Bank) provide the Insurer and each
Rating Agency prompt notice of any such transaction.

         In case at the time such successor by merger, conversion or
consolidation to the Indenture Trustee shall succeed to the trusts created by
this Indenture any of the Notes shall have been authenticated but not delivered,
any such successor to the Indenture Trustee may adopt the certificate of
authentication of any predecessor trustee, and deliver such Notes so
authenticated; and in case at that time any of the Notes shall not have been
authenticated, any successor to the Indenture Trustee may authenticate such
Notes either in the name of any predecessor hereunder or in the name of the
successor to the Indenture Trustee; and in all such cases such certificates
shall have the full force and effect of the certificate of the Indenture Trustee
pursuant to the Notes or this Indenture.

                  Section 6.10 Appointment of Co-Indenture Trustee or Separate
Indenture Trustee.

                  (a) Notwithstanding any other provision of this Indenture, at
any time, for the purpose of meeting any legal requirement of any jurisdiction
in which any part of the Collateral may at the time be located, the Indenture
Trustee shall have the power and may execute and deliver all instruments to
appoint one or more Persons to act as a co-trustee or co-trustees, jointly with
the Indenture Trustee, or separate trustee or separate trustees, of all or any
part of the Trust, and to vest in such Person or Persons, in such capacity and
for the benefit of the Noteholders, such title to the Collateral, or any part
hereof, and, subject to the other provisions of this Section, such powers,
duties, obligations, rights and trusts as the Indenture Trustee may consider
necessary or desirable. No co-trustee or separate trustee hereunder shall be
required to meet the terms of eligibility as a successor Indenture Trustee under
Section 6.11 and no notice to Noteholders of the appointment of any co-trustee
or separate trustee shall be required under Section 6.08.



                                      -40-
<PAGE>   46

                  (b) Every separate trustee and co-trustee shall, to the extent
permitted by law, be appointed and act subject to the following provisions and
conditions:

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

                           (ii) no trustee hereunder shall be personally liable
                  by reason of any act or omission of any other trustee
                  hereunder; and

                           (iii) the Indenture Trustee may at any time accept
                  the resignation of or remove any separate trustee or
                  co-trustee.

                  (c) Any notice, request or other writing given to the
Indenture Trustee shall be deemed to have been given to each of the then
separate trustees and co-trustees, as effectively as if given to each of them.
Every instrument appointing any separate trustee or co-trustee shall refer to
this Indenture and the conditions of this Article. Each separate trustee and
co-trustee, upon its acceptance of the trusts conferred, shall be vested with
the estates or property specified in its instrument of co-appointment, either
jointly with the Indenture Trustee or separately, as may be provided therein,
subject to all the provisions of this Indenture, specifically including every
provision relating to the conduct of, affecting the liability of, or affording
protection to, the Indenture Trustee. Every such instrument shall be filed with
the Indenture Trustee.

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

                  Section 6.11 Eligibility; Disqualification.

                  (a) The Indenture Trustee shall have a combined capital and
surplus of at least $50,000,000 as set forth in its most recent published annual
report of condition. The Indenture Trustee shall provide copies of such reports
to the Insurer upon request. The Indenture Trustee shall comply with TIA Section
310(b); provided, however, that there shall be excluded from the operation of
TIA Section 310(b)(1) any indenture or indentures under which other securities
of the Issuer are outstanding if the requirements for such exclusion set forth
in TIA Section 310(b)(1) are met.

<PAGE>   47

                  (b) If the long term debt rating of the Indenture Trustee
shall not be at least Baa3 from Moody's and BBB- from Standard & Poor's, the
Rating Agencies shall be given notice of such lower long-term debt rating.

                  Section 6.12 Preferential Collection of Claims Against Issuer.
The Indenture Trustee shall comply with TIA Section 311(a), excluding any
creditor relationship listed in TIA Section 311(b). An Indenture Trustee who has
resigned or been removed shall be subject to Section 311(a) to the extent
indicated.

                  Section 6.13 Representations and Warranties of Indenture
Trustee. The Indenture Trustee hereby makes the following representations and
warranties on which the Issuer and Noteholders shall rely:

                  (a) the Indenture Trustee is a corporation duly organized,
validly existing and in good standing under the laws of its place of
incorporation; and

                  (b) the Indenture Trustee has full power, authority and legal
right to execute, deliver, and perform this Indenture and shall have taken all
necessary action to authorize the execution, delivery and performance by it of
this Indenture.

                                   ARTICLE VII

                         NOTEHOLDERS' LISTS AND REPORTS

                  Section 7.01 Issuer to Furnish Indenture Trustee Names and
Addresses of Noteholders. The Issuer will furnish or cause to be furnished to
the Indenture Trustee (i) not more than five days after the earlier of (a) each
Record Date and (b) three months after the last Record Date, a list, in such
form as the Indenture Trustee may reasonably require, of the names and addresses
of the Holders of Notes as of such Record Date and (ii) at such other times as
the Indenture Trustee may request in writing, within 10 days after receipt by
the Issuer of any such request, a list of similar form and content as of a date
not more than ten days prior to the time such list is furnished; provided,
however, that so long as the Indenture Trustee is the Note Registrar, no such
list shall be required to be furnished. The Indenture Trustee or, if the
Indenture Trustee is not the Note Registrar, the Issuer shall furnish to the
Insurer in writing at such times as the Insurer may reasonably request a copy of
the list.

                  Section 7.02 Preservation of Information; Communications to
Noteholders.

                  (a) The Indenture Trustee shall preserve, in as current a form
as is reasonably practicable, the names and addresses of the Holders of Notes
contained in the most recent list furnished to the Indenture Trustee as provided
in Section 7.01 and the names and addresses of Holders of Notes received by the
Indenture Trustee in its capacity as Note Registrar. The Indenture Trustee may
destroy any list furnished to it as provided in such Section 7.01 upon receipt
of a new list so furnished.

                  (b) Noteholders may communicate pursuant to TIA Section 312(b)
with other Noteholders with respect to their rights under this Indenture or
under the Notes.

                  portions of any of the foregoing as the Commission may from

                  from time to time by the Commission such additional
                  information, documents and reports with respect to compliance
                  by the Issuer with the conditions and covenants of this
                  Indenture as may be required from time to time by such rules
                  and regulations; and

                           (iii) supply to the Indenture Trustee (and the

                  7.03(a) as may be required by rules and regulations prescribed
                  from time to time by the Commission.

                  (b) Unless the Issuer otherwise determines, the fiscal year of

                      ACCOUNTS, DISBURSEMENTS AND RELEASES

                  Section 8.01 Collection of Money.

                  (a) General. Except as otherwise expressly provided herein,
the Indenture Trustee may demand payment or delivery of, and shall receive and
collect, directly and without intervention or assistance of any fiscal agent or
other intermediary, all money and other property payable to or receivable by the
Indenture Trustee pursuant to this Indenture. The Indenture Trustee shall apply
all such money received by it as provided in this Indenture. Except as otherwise
expressly provided in this Indenture, if any default occurs in the making of any
payment or performance under any agreement or instrument that is part of the
Collateral, the Indenture Trustee



                                      -43-
<PAGE>   49

may take such action as may be appropriate to enforce such payment or
performance, including the institution and prosecution of appropriate
Proceedings. Any such action shall be without prejudice to any right to claim a
Default or Event of Default under this Indenture and any right to proceed
thereafter as provided in Article Five.

                  (b) Claims Under Policy. The Notes and the Certificates will
be insured by the Policy pursuant to the terms set forth therein,
notwithstanding any provisions to the contrary contained in this Indenture or
the Sale and Servicing Agreement. All amounts received under the Policy shall be
used solely for the payment to Securityholders of principal and interest on the
Notes and the Certificates.

                  Section 8.02 Trust Accounts.

                  (a) On or prior to the Closing Date, the Issuer shall cause
the Servicer to establish in the name of the Indenture Trustee, for the benefit
of the Noteholders and the Insurer, or in the name of the Trust Agent, for the
benefit of the Certificateholders and the Insurer, the Trust Accounts as
provided in Section 4.01 of the Sale and Servicing Agreement.

                  (b) On the Business Day immediately preceding each

shall cause funds to be withdrawn from the Collection Account equal to the
amount of Net Collections available with respect to such Distribution Date and
deposited into the Payment Account, as provided in Section 4.02(e) of the Sale
and Servicing Agreement. On each Distribution Date, based solely on the
Distribution Date Statement, the Indenture Trustee will apply the Net
Collections available with respect to the related Collection Period, together
with amounts, if any, withdrawn from the Spread Account, the Prefunding Account
and the Capitalized Interest Account or representing payment of the Policy Claim

                  Section 8.03 [RESERVED].

                  Section 8.04 Release of Collateral.

                  (a) Subject to the payment of its fees and expenses pursuant
to Section 6.07, the Indenture Trustee may, and when required by the provisions
of this Indenture shall, execute instruments to release property from the lien
of this Indenture, or convey the Indenture Trustee's interest in the same, in a
manner and under circumstances that are not inconsistent with the provisions of
this Indenture. No party relying upon an instrument executed by the Indenture
Trustee as provided in this Article shall be bound to ascertain the Indenture
Trustee's authority, inquire into the satisfaction of any conditions precedent
or see to the application of any monies.

                  (b) The Indenture Trustee shall, at such time as there are no
Notes Outstanding and all sums due the Indenture Trustee pursuant to Section
6.07 have been paid, release any remaining portion of the Collateral that
secured the Notes from the lien of this Indenture and release to the Issuer or
any other Person entitled thereto any funds then on deposit in the Trust
Accounts. The Indenture Trustee shall release property from the lien of this
Indenture pursuant to this Section 8.04(b) only upon receipt of an Issuer
Request accompanied by an Officer's Certificate, an Opinion of Counsel and (if
required by the TIA) Independent Certificates in accordance with TIA Sections
314(c) and 314(d)(1) meeting the applicable requirements of Section 11.01.

                  Section 8.05 Opinion of Counsel. The Indenture Trustee shall
receive at least seven days' notice when requested by the Issuer to take any
action pursuant to Section 8.04(a), accompanied by copies of any instruments
involved, and the Indenture Trustee shall also require, as a condition to such
action, an Opinion of Counsel, in form and substance satisfactory to the
Indenture Trustee (and not at the expense of the Indenture Trustee), stating the
legal effect of any such action, outlining the steps required to complete the
same, and concluding that all conditions



                                      -45-
<PAGE>   51

precedent to the taking of such action have been complied with and such action
will not materially and adversely impair the security for the Notes or the
rights of the Noteholders in contravention of the provisions of this Indenture;
provided, however, that such Opinion of Counsel shall not be required to express
an opinion as to the fair value of the Collateral. Counsel rendering any such
opinion may rely, without independent investigation, on the accuracy and
validity of any certificate or other instrument delivered to the Indenture
Trustee in connection with any such action.

                  created by this Indenture additional property;

                           (ii) to evidence the succession, in compliance with
                  the applicable provisions hereof, of another Person to the

                           (v) to cure any ambiguity, to correct or supplement
                  any provision herein or in any supplemental indenture which
                  may be inconsistent with any other provision herein or in any
                  supplemental indenture or the Basic Documents or to make any
                  other provisions with respect to matters or questions arising
                  under this Indenture or in any supplemental indenture;
                  provided that such action shall not adversely affect the
                  interests of the Holders of the Notes;

                           (vi) to evidence and provide for the acceptance of
                  the appointment hereunder by a successor trustee with respect
                  to the Notes and to add to or change any of the provisions of
                  this Indenture as shall be necessary to facilitate the
                  administration of the trusts hereunder by more than one
                  trustee, pursuant to the requirements of Article Six; or



                                      -46-
<PAGE>   52


                           (vii) to modify, eliminate or add to the provisions
                  of this Indenture to such extent as shall be necessary to
                  effect the qualification of this Indenture under the TIA or
                  under any similar federal statute hereafter enacted and to add
                  to this Indenture such other provisions as may he expressly
                  required by the TIA.

         The Indenture Trustee is hereby authorized to join in the execution of
any such supplemental indenture and to make any further appropriate agreements
and stipulations that may be therein contained.

                  (b) The Issuer and the Indenture Trustee, when authorized by
an Issuer Order, may, also without the consent of any of the Holders of the
Notes but with the consent of the Insurer and with prior notice to each Rating
Agency, enter into an indenture or indentures supplemental hereto for the
purpose of adding any provisions to, or changing in any manner or eliminating
any of the provisions of, this Indenture or of modifying in any manner the
rights of the Holders of the Notes under this Indenture; provided, however, that
such action shall not, as evidenced by an Opinion of Counsel, adversely affect
in any material respect the interests of any Noteholder.

                  Section 9.02 Supplemental Indentures With Consent of
Noteholders. The Issuer and the Indenture Trustee, when authorized by an Issuer
Order, also may, with prior notice to each Rating Agency, with the consent of
the Insurer and with the consent of the Holders of not less than 51% of the

Documents, no such supplemental indenture shall, without the consent of the
Holder of each Outstanding Note affected thereby:

                  (a) change the date of payment of any installment of principal

                  (b) impair the right to institute suit for the enforcement of

redemption, on or after the Redemption Date);

                  (c) reduce the percentage of the Outstanding Amount of the

the lien created by this Indenture on any property at any time subject hereto or
deprive the Holder of any Note of the security provided by the lien created by
this Indenture.

         The Indenture Trustee may in its discretion determine whether or not
any Notes would be affected by any supplemental indenture and any such
determination shall be conclusive upon the Holders of all Notes, whether
theretofore or thereafter authenticated and delivered hereunder. The Indenture
Trustee shall not be liable for any such determination made in good faith.

         It shall not be necessary for any act of Noteholders under this Section
to approve the particular form of any proposed supplemental indenture, but it
shall be sufficient if such act shall approve the substance thereof.

         Promptly after the execution by the parties hereto of any supplemental
indenture pursuant to this Section, the Indenture Trustee shall mail to the
Holders of the Notes to which such amendment or supplemental indenture relates a
notice setting forth in general terms the substance of such supplemental
indenture. Any failure of the Indenture Trustee to mail such notice, or any
defect therein, shall not, however, in any way impair or affect the validity of
any such supplemental indenture.

                  Section 9.03 Execution of Supplemental Indentures. In
executing, or permitting the additional trusts created by, any supplemental
indenture permitted by this Article or the modifications thereby of the trusts
created by this Indenture, the Indenture Trustee shall be entitled to receive,

an Opinion of Counsel stating that the execution of such supplemental indenture
is authorized or permitted by this Indenture. The Indenture Trustee may, but

under this Indenture or otherwise.

                  Section 9.04 Effect of Supplemental Indenture. Upon the
execution of any supplemental indenture pursuant to the provisions hereof, this
Indenture shall be and be deemed to be modified and amended in accordance
therewith with respect to the Notes affected thereby, and the respective rights,

this Indenture of the parties hereto and the Holders of the Notes shall
thereafter be determined, exercised and enforced hereunder subject in all
respects to such modifications and amendments, and all the terms and conditions
of any such supplemental indenture shall be and be deemed to be part of the
terms and conditions of this Indenture for any and all purposes.

Indenture Trustee shall so determine, new notes so modified as to conform, in
the opinion of the Indenture Trustee and the Issuer, to any such supplemental
indenture may be prepared and executed by the Issuer and authenticated and
delivered by the Indenture Trustee in exchange for Outstanding Notes.

                               REDEMPTION OF NOTES

                  Section 10.01 Redemption. In the event that the Servicer
pursuant to Section 8.01(a) of the Sale and Servicing Agreement purchases the
corpus of the Trust, the Notes are subject to redemption in whole, but not in
part, on the Distribution Date on which such repurchase occurs, for a purchase
price equal to the Redemption Price; provided, however, that the Issuer has
available funds sufficient to pay the Redemption Price. The Seller, the Servicer
or the Issuer shall furnish the Insurer and each Rating Agency notice of such
redemption. If the Notes are to be redeemed pursuant to this Section 10.01, the
Servicer or the Issuer shall furnish notice of such election to the Indenture
Trustee not later than 20 days prior to the Redemption Date and the Issuer shall
deposit with the Indenture Trustee in the Note Distribution Account the
Redemption Price of the Notes to be redeemed whereupon all such Notes shall be
due and payable on the Redemption Date upon the furnishing of a notice complying
with Section 10.02 to each Holder of the Notes.

                  Section 10.02 Form of Redemption Notice. Notice of redemption
under Section 10.01 shall be given by the Indenture Trustee by first-class mail,
postage prepaid, mailed not less than five days prior to the applicable
Redemption Date to each Holder of Notes, as of the close of business on the
Record Date preceding the applicable Redemption Date, at such Holder's address
appearing in the Note Register. In addition, the Administrator shall notify the
Insurer and Rating Agencies upon the redemption of any Class of Notes, pursuant
to Section 1(a)(i)(AA) of the Administration Agreement.

         All notices of redemption shall state:

                           (i) the Redemption Date;

                           (ii) the Redemption Price; and

                           (iii) the place where such Notes are to be

                  provided in Section 3.02).



                                      -49-
<PAGE>   55

         Notice of redemption of the Notes shall be given by the Indenture
Trustee in the name and at the expense of the Issuer. Failure to give notice of
redemption, or any defect therein, to any Holder of any Note shall not impair or
affect the validity of the redemption of any other Note.

                  Section 10.03 Notes Payable on Redemption Date. The Notes or
portions thereof to be redeemed shall, following notice of redemption (if any)
as required by Section 10.02, on the Redemption Date become due and payable at
the Redemption Price and (unless the Issuer shall default in the payment of the
Redemption Price) no interest shall accrue on the Redemption Price for any
period after the date to which accrued interest is calculated for purposes of
calculating the Redemption Price.

                  express an informed opinion as to whether or not such covenant
                  or condition has been complied with; and

                           (iv) a statement as to whether, in the opinion of

         Indenture Trustee and the Insurer an Independent Certificate as to the
         named matters, if the fair value to the Issuer of the property to be so
         deposited and of all other such property made the basis of any such
         withdrawal or release since the commencement of the then-current fiscal
         year of the Issuer, as set forth in the Officer's Certificates
         delivered pursuant to clause (i) above and this clause (ii), is 10% or
         more of the Outstanding Amount of the Notes, but such Officer's
         Certificate need not be furnished with respect to any property so

         Indenture Trustee and the Insurer an Independent Certificate as to the
         same matters if the fair value of the property or securities and of all
         other property or securities released from the lien created by this
         Indenture since the commencement of the then current fiscal year, as
         set forth in the Officer's Certificate required by clause (iii) above
         and this clause (iv), equals 10% or more of the Outstanding Amount of
         the Notes, but such Officer's Certificate need not be furnished in the
         case of any release of property or securities if the fair value thereof
         as set forth in the related Officer's Certificate is less than $25,000
         or less than one percent of the then Outstanding Amount of the Notes.

                  Section 11.02 Form of Documents Delivered to Indenture
Trustee. In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

         Any certificate or opinion of an Authorized Officer of the Issuer may
be based, insofar as it relates to legal matters, upon a certificate or opinion
of, or representations by, counsel, unless such officer knows, or in the
exercise of reasonable care should know, that the certificate or opinion or
representations with respect to the matters upon which his certificate or
opinion is based are



                                      -51-
<PAGE>   57

erroneous. Any such certificate of an Authorized Officer or Opinion of Counsel
may be based, insofar as it relates to factual matters, upon a certificate or
opinion of, or representations by, an officer or officers of the Servicer, the
Seller or the Issuer, stating that the information with respect to such factual
matters is in the possession of the Servicer, the Seller or the Issuer, unless
such officer or counsel knows, or in the exercise of reasonable care should
know, that the certificate or opinion or representations with respect to such
matters are erroneous.

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

         Whenever in this Indenture, in connection with any application or
certificate or report to the Indenture Trustee, it is provided that the Issuer
shall deliver any document as a condition of the granting of such application,
or as evidence of the Issuer's compliance with any term hereof, it is intended
that the truth and accuracy, at the time of the granting of such application or
at the effective date of such certificate or report (as the case may be), of the
facts and opinions stated in such document shall in such case be conditions
precedent to the right of the Issuer to have such application granted or to the
sufficiency of such certificate or report. The foregoing shall not, however, be
construed to affect the Indenture Trustee's right to rely upon the truth and
accuracy of any statement or opinion contained in any such document as provided
in Article Six.

                  Section 11.03 Acts of Noteholders.

                  (a) Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by Noteholders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Noteholders in person or by agents
duly appointed in writing; and except as herein otherwise expressly provided,
such action shall become effective when such instrument or instruments are
delivered to the Indenture Trustee, and, where it is hereby expressly required,
to the Issuer. Such instrument or instruments (and the action embodied therein
and evidenced thereby) are herein sometimes referred to as the "Act" of the
Noteholders signing such instrument or instruments. Proof of execution of any
such instrument or of a writing appointing any such agent shall be sufficient
for any purpose of this Indenture and (subject to Section 6.01) conclusive in
favor of the Indenture Trustee and the Issuer, if made in the manner provided in
this Section.

                  (b) The fact and date of the execution by any Person of any
such instrument or writing may be proved in any manner that the Indenture
Trustee deems sufficient.

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

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

                  Section 11.04 Notices, etc., to Indenture Trustee, Issuer,
Insurer and Rating Agencies.

                  (a) Any request, demand, authorization, direction, notice,
consent, waiver or Act of Noteholders or other documents provided or permitted
by this Indenture shall be in writing and if such request, demand,
authorization, direction, notice, consent, waiver or Act of Noteholders is to be
made upon, given or furnished to or filed with:

                           (i) the Indenture Trustee by any Noteholder or by the
                  Issuer shall be sufficient for every purpose hereunder if in
                  writing, personally delivered, sent by facsimile transmission
                  and confirmed or mailed by overnight service, to or with the
                  Indenture Trustee at its Corporate Trust Office;

                           (ii) the Issuer by the Indenture Trustee or by any
                  Noteholder shall be sufficient for every purpose hereunder if
                  in writing, personally delivered, sent by facsimile
                  transmission and confirmed or mailed by overnight service, to
                  the Issuer addressed to: Onyx Acceptance Owner Trust 1999-D,
                  in care of Bankers Trust (Delaware), as Owner Trustee, 1011
                  Centre Road, Suite 200, Wilmington, Delaware 19805-1266,
                  Attention: Corporate Trust Administration Department, or at
                  any other address furnished in writing to the Indenture
                  Trustee by the Issuer; or

                           (iii) the Insurer by the Issuer or the Indenture
                  Trustee shall be sufficient for any purpose hereunder if in
                  writing, personally delivered, sent by facsimile transmission
                  and confirmed or mailed by overnight service, to the Insurer
                  addressed to: MBIA Insurance Corporation, 113 King Street,
                  Armonk, New York 10504, Attention: Insured Portfolio
                  Management, Structured Finance.

                  (b) Notices required to be given to the Rating Agencies by the
Issuer, the Indenture Trustee or the Owner Trustee shall be in writing,
personally delivered, sent by facsimile transmission and confirmed or mailed by
overnight service, to (i) in the case of Moody's, at the following address:
Moody's Investors Service, Inc., ABS Monitoring Department, 99 Church Street,
New York, New York 10007 and (ii) in the case of Standard & Poor's, at the
following address: Standard & Poor's Ratings Services, 55 Water Street (41st
Floor), New York, New York 10041, Attention: Asset Backed Surveillance
Department; or as to each of the foregoing, at such other address as shall be
designated by written notice to the other parties.

                  Section 11.05 Notices to Noteholders; Waiver. Where this
Indenture provides for notice to Noteholders of any event, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing
and mailed, first-class, postage prepaid to each Noteholder affected by such
event, at his address as it appears on the Note Register, not later than the
latest date, and not earlier than the earliest date, prescribed for the giving
of such notice. In any case where notice to Noteholders is given by mail,
neither the failure to mail such notice nor any defect in any notice so mailed
to any particular Noteholder shall affect the sufficiency of such notice with
respect to other Noteholders, and any notice that is mailed in the manner herein
provided shall conclusively be presumed to have been duly given.

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



                                      -53-
<PAGE>   59

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

         Where this Indenture provides for notice to the Rating Agencies,
failure to give such notice shall not affect any other rights or obligations
created hereunder, and shall not under any circumstance constitute a Default or
Event of Default.

                  Section 11.06 Alternate Payment and Notice Provisions.
Notwithstanding any provision of this Indenture or any of the Notes to the
contrary, the Issuer may enter into any agreement with any Holder of a Note
providing for a method of payment, or notice by the Indenture Trustee or any
Paying Agent to such Holder, that is different from the methods provided for in
this Indenture for such payments or notices. The Issuer will furnish to the
Indenture Trustee a copy of each such agreement and the Indenture Trustee will
cause payments to be made and notices to be given in accordance with such
agreements.

                  Section 11.07 Conflict With Trust Indenture Act. If any
provision hereof limits, qualifies or conflicts with another provision hereof
that is required to be included in this indenture by any of the provisions of
the Trust Indenture Act, such required provision shall control.

         The provisions of TIA Sections 310 through 317 that impose duties on
any Person (including the provisions automatically deemed included herein unless
expressly excluded by this Indenture) are a part of and govern this Indenture,
whether or not physically contained herein.

                  Section 11.08 Effect of Headings and Table of Contents. The
Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.

                  Section 11.09 Successors and Assigns. All covenants and
agreements in this Indenture and the Notes by the Issuer shall bind its
successors and assigns, whether so expressed or not. All agreements of the
Indenture Trustee in this Indenture shall bind its successors, co-trustees and
agents.

                  Section 11.10 Separability. In case any provision in this
Indenture or in the Notes shall be invalid, illegal or unenforceable, the
validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby.

                  Section 11.11 Benefits of Indenture. The Insurer and its
successors and assigns shall be a third-party beneficiary to the provisions of
this Indenture, and shall be entitled to rely upon and directly to enforce such
provisions of this Indenture so long as no Insurer Default shall have occurred
and be continuing. Nothing in this Indenture or in the Notes, express or
implied, shall give to any Person, other than the parties hereto and their
successors hereunder, and the Noteholders, and any other party secured
hereunder, and any other Person with an ownership interest in any part of the
Collateral, any benefit or any legal or equitable right, remedy or claim under
this Indenture. The Insurer may disclaim any of its rights and powers under this
Indenture, but not its duties and obligations under the Policy, upon delivery of
a written notice to the Indenture Trustee.



                                      -54-
<PAGE>   60

                  Section 11.12 Legal Holidays. In any case where the date on
which any payment is due shall not be a Business Day, then (notwithstanding any
other provision of the Notes or this Indenture) payment need not be made on such
date, but may be made on the next succeeding Business Day with the same force
and effect as if made on the date on which nominally due, and no interest shall
accrue for the period from and after any such nominal date.

                  Section 11.13 Governing Law. THIS INDENTURE SHALL BE CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK AND THE OBLIGATIONS,
RIGHTS, AND REMEDIES OF THE PARTIES UNDER THIS INDENTURE SHALL BE DETERMINED IN
ACCORDANCE WITH SUCH LAWS.

                  Section 11.14 Counterparts. This Indenture may be executed in
several counterparts, each of which shall be an original and all of which shall
constitute but one and the same instrument.

                  Section 11.15 Recording of Indenture. If this Indenture is
subject to recording in any appropriate public recording offices, such recording
is to be effected by the Issuer and at its expense accompanied by an Opinion of
Counsel (which may be counsel to the Indenture Trustee or any other counsel
reasonably acceptable to the Indenture Trustee and the Insurer) to the effect
that such recording is necessary either for the protection of the Noteholders or
any other Person secured hereunder or for the enforcement of any right or remedy
granted to the Indenture Trustee under this Indenture.

                  Section 11.16 Trust Obligation. No recourse may be taken,
directly or indirectly, with respect to the obligations of the Issuer, the Owner
Trustee or the Indenture Trustee on the Notes or under this Indenture or any
certificate or other writing delivered in connection herewith or therewith,
against (i) the Indenture Trustee or the Owner Trustee in its individual
capacity, (ii) any owner of a beneficial interest in the Issuer or (iii) any
partner, owner, beneficiary, agent, officer, director, employee or agent of the
Indenture Trustee or the Owner Trustee in its individual capacity, any Holder of
a beneficial interest in the Issuer, the Owner Trustee or the Indenture Trustee
or of any successor or assign of the Indenture Trustee or the Owner Trustee in
its individual capacity, except as any such Person may have expressly agreed (it
being understood that the Indenture Trustee and the Owner Trustee have no such
obligations in their individual capacity) and except that any such partner,
owner or beneficiary shall be fully liable, to the extent provided by applicable
law, for any unpaid consideration for stock, unpaid capital contribution or
failure to pay any installment or call owing to such entity. For all purposes of
this Indenture, in the performance of any duties or obligations of the Issuer
hereunder, the Owner Trustee shall be subject to, and entitled to the benefits
of, the terms and provisions of Articles Six, Seven and Eight of the Trust
Agreement.

                  Section 11.17 No Petition. The parties hereto, by entering
into this Indenture, and each Noteholder, by accepting a Note or a beneficial
interest in a Note, hereby covenant and agree that they will not at any time
institute against the Seller or the Issuer, or join in any institution against
the Seller or the Issuer of, any bankruptcy, reorganization, arrangement,
insolvency or liquidation proceedings, or other proceedings under any United
States Federal or state bankruptcy or similar law in connection with any
obligations relating to the Notes, this Indenture or any of the other Basic
Documents.

                  Section 11.18 Inspection. The Issuer agrees that, on
reasonable prior notice, it will permit any representative of the Indenture
Trustee or of the Insurer, during the Issuer's normal business hours, to examine
all the books of account, records, reports and other papers of the Issuer, to
make copies and extracts therefrom, to cause such books to be audited by
independent certified public accountants, and to discuss the Issuer's affairs,
finances and accounts with the Issuer's officers, employees and independent
certified public accountants, all at such reasonable times and as often as may
be reasonably requested. The Indenture Trustee and the Insurer shall and shall
cause their respective representatives to hold in confidence all such
information except to the extent disclosure may be required by law (and all
reasonable applications for confidential treatment are unavailing) and except to
the extent that the Indenture Trustee or the Insurer may reasonably determine
that such disclosure is consistent with its obligations hereunder.

                  Section 11.19 Limitation of Liability of Owner Trustee.
Notwithstanding anything contained herein to the contrary, this instrument has
been countersigned by Bankers Trust (Delaware) not in its individual capacity
but solely in its capacity as Owner Trustee of the Issuer and in no event shall
Bankers Trust (Delaware) in its individual capacity or any beneficial owner of
the Issuer have any liability for the representations, warranties, covenants,
agreements or other obligations of the Issuer hereunder, as to all of which
recourse shall be had solely to the assets of the Issuer. For all purposes of
this Agreement, in the performance of any duties or obligations of the Issuer
hereunder, the Owner Trustee shall be subject to, and entitled to the benefits
of, the terms and provisions of Articles Six, Seven and Eight of the Trust
Agreement. Notwithstanding anything herein to the contrary, Section 2.07 of the
Trust Agreement shall remain in full force and effect.

                  Section 11.20 Certain Matters Regarding the Insurer. So long
as an Insurer Default shall not have occurred and be continuing, the Insurer
shall have the right to exercise all rights, including voting rights, which the
Noteholders, Certificateholders or Residual Interestholders are entitled to
exercise pursuant to this Indenture, without any consent of such Noteholders,
Certificateholders or Residual Interestholders; provided, however, that without
the consent of each Noteholder, Certificateholder or Residual Interestholder
affected thereby, the Insurer shall not exercise such rights to amend this
Indenture in any manner that would (i) reduce the amount of, or delay the timing
of, collections of payments on the Contracts or distributions which are required
to be made on any Note, Certificate or Residual Interest Instrument, (ii)
adversely affect in any material respect the interests of the Holders of any
Notes, Certificates or Residual Interest Instruments, or (iii) alter the rights
of any such Holder to consent to such amendment.

         Notwithstanding any provision in this Indenture to the contrary, in the
event an Insurer Default shall have occurred and be continuing, the Insurer
shall not have the right to take any action under this Agreement or to control
or direct the actions of the Trust, the Seller, the Indenture Trustee, the Owner
Trustee or the Trust Agent pursuant to the terms of this Indenture, nor shall
the consent of the Insurer be required with respect to any action (or waiver of
a right to take action) to be taken by the Trust, the Seller, the Indenture
Trustee, the Owner Trustee, the Trust Agent or the Holders of the Notes, the
Certificates, or the Residual Interest Instruments; provided, that the consent
of the Insurer shall be required at all times with respect to any amendment of
this Indenture.

        the Noteholders; and

               (vi) to engage in those activities, including entering into
        agreements, that are necessary to accomplish the foregoing or are
        incidental thereto or connected therewith.

title to all the Trust Estate shall be vested at all times in the Trust as a
separate legal entity except where applicable law in any jurisdiction requires
title to any part of the Trust Estate to be vested in a trustee or trustees, in
which case title shall be deemed to be vested in the Owner Trustee and/or a
separate trustee, as the case may be.

        The Owners shall not have legal title to any part of the Trust Estate.
The Owners shall be entitled to receive distributions with respect to their
undivided ownership interest therein only in accordance with Articles Five and
Nine. No transfer, by operation of law or otherwise, of any right, title or

of the Trust Estate.

        (a) Net income of the Trust for any month, as determined for federal
income tax purposes (and each item of income, gain, loss and deduction entering
into the computation thereof), shall be allocated:

        the end of such month, in proportion to their ownership of the principal
        amount of Certificates on such date, net income in an amount up to the
        sum of (A) the Certificate Interest Distributable Amount for such month,
        (B) interest on the excess, if any, of the Certificate Interest
        Distributable Amount for the preceding Distribution Date over the amount
        in respect of interest that is actually deposited in the Certificate
        Distribution Account on such preceding Distribution Date, to the extent
        permitted by law, at the Certificate Rate from such preceding
        Distribution






                                      -8-
<PAGE>   13

        Date through the current Distribution Date, (C) the portion of the
        market discount on the Contracts accrued during such month that is
        allocable to the excess, if any, of the initial aggregate principal
        amount of the Trust Certificates over their initial aggregate issue
        price and (D) any other amounts of income payable to the
        Certificateholders for such month; such sum to be reduced by any
        amortization by the Trust of premium on Contracts that corresponds to
        any excess of the issue price of Trust Certificates over their principal
        amount; and

               (ii) among the Residual Interestholders in proportion to the
        Percentage Interest of the Residual Interest of each Residual
        Interestholder, to extent of any remaining net income.

        (b) If the net income of the Trust for any calendar month is
insufficient for the allocations described in Section 2.10(a)(i), subsequent net
income shall first be allocated to make up such shortfall before being allocated
as provided in Section 2.10(a)(ii). Net losses of the Trust, if any, for any
calendar month as determined for federal income tax purposes (and each item of
income, gain, loss and deduction entering into the computation thereof) shall be
allocated to the Residual Interestholders, to the extent the Residual
Interestholders are reasonably expected to bear the economic burden of such net
losses, and any remaining net losses shall be allocated among the Certificate
Owners as of the first day following the end of such month in proportion to
their ownership of the principal amount of Certificates on such day. Any
indebtedness allocated pursuant to Treasury Regulation Section 1.752-3(a)(3)
shall be allocated to the Residual Interest. The Depositor is authorized to
modify the allocations in this paragraph if necessary or appropriate, in its
sole discretion, for the allocations to fairly reflect the income, gain, loss
and deduction to the Depositor or to the Owners, or as otherwise required by the
Code.


                                   ARTICLE III

                  TRUST CERTIFICATES AND TRANSFER OF INTERESTS

        Section 3.01 Initial Ownership. Upon the formation of the Trust by the
contribution by the Depositor pursuant to Section 2.05 and until the issuance of
the Trust Certificates, the Depositor shall be the sole beneficiary of the
Trust.

        Section 3.02 The Trust Certificates and the Notes.

        (a) The Certificates shall be issuable in minimum denominations of
$1,000 and integral multiples thereof, except that one Certificate may be issued
in a different denomination. The Residual Interest Instruments shall not be
issued with a principal amount. The Trust Certificates shall be executed by the
Owner Trustee on behalf of the Trust by manual or facsimile signature of an
authorized officer of the Owner Trustee, and authenticated by the Trust Agent by
the manual or facsimile signature of an authorized officer of the Trust Agent
and shall be deemed to have been validly issued when so executed and
authenticated. Trust Certificates bearing the manual or facsimile signatures of
individuals who were, at the time when such signatures were affixed, authorized
to sign on behalf of the Owner Trustee or the Trust Agent shall be validly
issued by the Trust, notwithstanding that such individuals or any of them have
ceased to be so authorized prior to the execution, authentication and delivery
of such Trust Certificates or did not hold such offices at






                                      -9-
<PAGE>   14

the date of such Trust Certificates. All Trust Certificates shall be dated the
date of their authentication.

        (b) The Notes shall be executed by the Owner Trustee on behalf of the
Trust by manual or facsimile signature of an authorized officer of the Owner
Trustee, and shall be authenticated as provided in the Indenture. Notes bearing
the manual or facsimile signature of an individual who was, at the time when
such signature was affixed, authorized to sign on behalf of the Owner Trustee
shall be deemed to have been validly executed by the Trust, notwithstanding that
such individual has ceased to be so authorized prior to the execution and
delivery of such Notes or did not hold such office at the date of such Notes.

        Section 3.03 Execution, Authentication and Delivery of Trust
Certificates and Notes. The Owner Trustee shall cause to be executed,
authenticated and delivered upon the order of the Depositor, in exchange for the
Contracts and the other assets of the Trust, simultaneously with the sale,
assignment and transfer to the Trust of the Contracts, and such other assets,
(a) (i) Certificates in authorized denominations equaling in the aggregate the
Original Certificate Balance, and (ii) the Residual Interest Instruments
representing 100% of the Percentage Interests of the Residual Interest,
evidencing the entire ownership of the Trust, and (b) Notes executed by the
Trust in aggregate principal amount of, in the case of the (i) Class A-1 Notes,
$59,000,000, (ii) Class A-2 Notes, $120,000,000, (iii) Class A-3 Notes,
$100,000,000 and (iv) Class A-4 Notes, $87,600,000. The Trust Agent is hereby
authorized to direct, on behalf of the Trust, the Indenture Trustee to
authenticate and deliver the Notes upon the order of the Depositor. No Trust
Certificate shall entitle its Holder to any benefit under this Agreement, or be
valid for any purpose, unless there appears on such Trust Certificate a
certificate of authentication substantially in the form set forth in the forms
of Trust Certificate attached hereto as Exhibit C and D, executed by the Trust
Agent or another authenticating agent of the Owner Trustee, by manual or
facsimile signature, and such certificate upon any Trust Certificate shall be
conclusive evidence, and the only evidence, that such Trust Certificate has been
duly authenticated and delivered hereunder. Upon issuance, authorization and
delivery pursuant to the terms hereof, the Trust Certificates will be entitled
to the benefits of this Agreement. All Trust Certificates shall be dated the
date of their authentication.

        Section 3.04 Registration of Transfer and Exchange of Trust
Certificates.

        (a) The Certificate Registrar shall keep or cause to be kept, a
Certificate Register, subject to such reasonable regulations as it may
prescribe. The Certificate Register shall provide for the registration of Trust
Certificates and transfers and exchanges of Trust Certificates as provided
herein. The Trust Agent, as agent for the Trust, is hereby initially appointed
Certificate Registrar for the purpose of registering Trust Certificates and
transfers and exchanges of Trust Certificates as herein provided. In the event
that, subsequent to the Closing Date, the Trust Agent notifies the Servicer that
the Trust Agent is unable to act as Certificate Registrar, the Servicer shall
appoint another bank or trust company, having an office or agency located in The
City of New York, agreeing to act in accordance with the provisions of this
Agreement applicable to it, and otherwise acceptable to the Depositor, to act as
successor Certificate Registrar hereunder.

        (b) Upon surrender for registration of transfer of any Trust Certificate
at the office of the Certificate Registrar, the Owner Trustee shall execute,
authenticate and deliver (or shall cause the Trust Agent, as its authenticating
agent, to authenticate and deliver), in the name of the designated






                                      -10-
<PAGE>   15

transferee or transferees, one or more new Trust Certificates in authorized
denominations of a like aggregate principal amount.

        (c) At the option of a Holder of a Trust Certificate, Trust Certificates
may be exchanged for other Trust Certificates in authorized denominations of a
like aggregate principal amount, upon surrender of the Trust Certificates to be
exchanged at the office of the Certificate Registrar. Whenever any Trust
Certificates are so surrendered for exchange, the Owner Trustee on behalf of the
Trust shall execute, authenticate and deliver (or shall cause the Trust Agent,
as its authenticating agent, to authenticate and deliver) the Trust Certificates
that the Holder making the exchange is entitled to receive. Every Trust
Certificate presented or surrendered for registration of transfer or exchange
shall be accompanied by a written instrument of transfer in form satisfactory to
the Trust Agent and the Certificate Registrar duly executed by the Holder
thereof or his attorney duly authorized in writing. In addition, each Residual
Interest Instrument presented or surrendered for registration of transfer and
exchange must be accompanied by a letter from the prospective Owner certifying
as to the representations set forth in Section 3.14(a) and (b).

        (d) No service charge shall be made for any registration of transfer or
exchange of Trust Certificates, but the Owner Trustee or, on its behalf, the
Trust Agent, may require payment of a sum sufficient to cover any tax or
governmental charge that may be imposed in connection with any transfer or
exchange of Trust Certificates.

        (e) All Trust Certificates surrendered for registration of transfer or
exchange, if surrendered to any agent of the Owner Trustee under this Agreement,
shall be delivered to the Trust Agent and promptly canceled by it, or, if
surrendered to the Trust Agent, shall be promptly canceled by it, and no Trust
Certificates shall be issued in lieu thereof except as expressly permitted by
any of the provisions of this Agreement. The Trust Agent shall dispose of
canceled Trust Certificates in accordance with the normal industry practice.

        Section 3.05 Mutilated, Destroyed, Lost or Stolen Trust Certificates. If
(a) any mutilated Trust Certificate is surrendered to the Certificate Registrar,
or the Certificate Registrar receives evidence to its satisfaction of the
destruction, loss or theft of any Trust Certificate, and (b) there is delivered
to the Certificate Registrar and the Trust Agent such security or indemnity as
may be required by them to save each of them harmless, then, in the absence of
notice that such Trust Certificate has been acquired by a bona fide purchaser,
the Owner Trustee on behalf of the Trust shall execute and the Trust Agent, as
its authenticating agent, shall authenticate and deliver, in exchange for or in
lieu of any such mutilated, destroyed, lost or stolen Trust Certificate, a new
Trust Certificate of like tenor and fractional undivided interest. In connection
with the issuance of any new Trust Certificate under this Section, the Owner
Trustee or, on its behalf, the Trust Agent, may require the payment by the
Holder of a sum sufficient to cover any tax or other governmental charge that
may be imposed in relation thereto. Any duplicate Trust Certificate issued
pursuant to this Section shall constitute complete and indefeasible evidence of
ownership in the Trust, as if originally issued, whether or not the lost, stolen
or destroyed Trust Certificate shall be found at any time.

        Section 3.06 Persons Deemed Owners. Prior to due presentation of a Trust
Certificate for registration of transfer, the Owner Trustee, the Trust Agent,
the Certificate Registrar, any Paying Agent and any of their respective agents
may treat the Person in whose name any Trust Certificate is registered as the
owner of such Trust Certificate for the purpose of receiving distributions
pursuant to Section 5.02 and for all other purposes whatsoever, and none of the
Owner Trustee, the Trust






                                      -11-
<PAGE>   16

Agent, the Certificate Registrar, any Paying Agent or any of their respective
agents shall be affected by any notice to the contrary.

        Section 3.07 Access to List of Owners' Names and Addresses. The Trust
Agent shall furnish or cause to be furnished to the Servicer, the Insurer and
the Depositor, within 15 days after receipt by the Trust Agent of a written
request therefor from the Servicer, the Insurer or the Depositor, a list, in
such form as the Servicer, the Insurer or the Depositor may reasonably require,
of the names and addresses of the Owners as of the most recent Record Date. If
three or more Certificateholders, or one or more Holders of Certificates
evidencing not less than 25% of the Percentage Interests of the Certificates
(hereinafter referred to as "APPLICANTS"), apply in writing to the Trust Agent,
and such application states that the Applicants desire to communicate with other
Certificateholders with respect to their rights hereunder or under the
Certificates and such application is accompanied by a copy of the communication
that such Applicants propose to transmit, then the Trust Agent shall, within
five Business Days after the receipt of such application, afford such Applicants
access, during normal business hours, to the current list of Certificateholders.
Each Owner, by receiving and holding a Trust Certificate, agrees with the
Servicer, the Depositor, the Owner Trustee and the Trust Agent that none of the
Servicer, the Depositor, the Owner Trustee or the Trust Agent shall be held
accountable by reason of the disclosure of any such information as to its name
and address hereunder, regardless of the source from which such information was
derived.

        Section 3.08 Maintenance of Office or Agency. The Trust Agent shall
maintain in the City of New York an office or offices or agency or agencies
where Trust Certificates may be surrendered for registration of transfer or
exchange and where notices and demands to or upon the Trust Agent in respect of
the Trust Certificates and the Basic Documents may be served. The Trust Agent
hereby designates the office of The Chase Manhattan Bank at the address provided
under the definition of the term "TRUST AGENT OFFICE" as its office for such
purposes. The Trust Agent shall give prompt written notice to the Owner Trustee,
the Depositor, the Servicer and to Certificateholders of any change in the
location of the Certificate Register or any such office or agency.

        Section 3.09 Temporary Trust Certificates. Pending the preparation of
definitive Trust Certificates, the Owner Trustee, on behalf of the Trust, may
execute, authenticate and deliver, temporary Trust Certificates that are
printed, lithographed, typewritten, mimeographed or otherwise produced, in any
authorized denomination, substantially of the tenor of the definitive Trust
Certificates in lieu of which they are issued. If temporary Trust Certificates
are issued, the Depositor will cause definitive Trust Certificates to be
prepared without unreasonable delay. After the preparation of definitive Trust
Certificates, the temporary Trust Certificates shall be exchangeable for
definitive Trust Certificates upon surrender of the temporary Trust Certificates
at the office or agency to be maintained as provided in Section 3.08, without
charge to the Holder. Upon surrender for cancellation of any one or more
temporary Trust Certificates, the Owner Trustee shall execute, authenticate and
deliver (or shall cause the Trust Agent, as its authenticating agent, to
authenticate and deliver) in exchange therefor a like principal amount of
definitive Trust Certificates in authorized denominations. Until so exchanged,
the temporary Trust Certificates shall in all respects be entitled to the same
benefits hereunder as definitive Trust Certificates.

        Section 3.10 Appointment of Paying Agent. The Owner Trustee, on behalf
of the Trust, hereby appoints the Trust Agent as Paying Agent under this
Agreement. The Paying Agent shall make distributions to Certificateholders and
to Residual Interestholders from the Certificate Distribution Account pursuant
to Section 5.02 hereof and shall report the amounts of such






                                      -12-
<PAGE>   17

        distributions to the Owner Trustee. The Paying Agent shall have the
revocable power to withdraw funds from the Certificate Distribution Account for
the purpose of making the distributions referred to above. The Owner Trustee on
behalf of the Trust may revoke such power and remove the Paying Agent if the
Owner Trustee is directed in writing to do so by the Administrator. Each Paying
Agent shall be permitted to resign as Paying Agent upon 30 days' written notice
to the Trust. In the event that the Trust Agent shall no longer be the Paying
Agent, the Administrator shall appoint a successor to act as Paying Agent (which
shall be a bank or trust company acceptable to the Insurer). The Administrator
shall cause such successor Paying Agent or any additional Paying Agent appointed
by the Administrator to execute and deliver to the Trust an instrument in which
such successor Paying Agent or additional Paying Agent shall agree with the
Trust that, as Paying Agent, such successor Paying Agent or additional Paying
Agent will hold all sums, if any, held by it for payment to the
Certificateholders and to the Residual Interestholders in trust for the benefit
of the Certificateholders and the Residual Interestholders entitled thereto
until such sums shall be paid to such Certificateholders and Residual
Interestholders. The Paying Agent shall return all unclaimed funds to the Trust
and upon removal of a Paying Agent such Paying Agent shall also return all funds
in its possession to the Trust. The provisions of Sections 7.01, 7.03, 7.04 and
8.01 shall apply to the Trust Agent also in its role as Paying Agent, for so
long as the Trust Agent shall act as Paying Agent and, to the extent applicable,
to any other paying agent appointed hereunder. Any reference in this Agreement
to the Paying Agent shall include any co-paying agent unless the context
requires otherwise. Notwithstanding anything herein to the contrary, the Trust
Agent and the Paying Agent shall be the same entity as the Indenture Trustee
under the Indenture and the Sale and Servicing Agreement, unless an Insurer
Default has occurred and is continuing. In such event, the Trust Agent and the
Paying Agent shall resign and the Owner Trustee shall assume the duties and
obligations of the Trust Agent and the Paying Agent hereunder and under the Sale
and Servicing Agreement.

        Section 3.11 Book-Entry Certificates. The Certificates upon original
issuance will be issued in the form of one or more typewritten certificates
representing the Book-Entry Trust Certificates, to be delivered to DTC, the
initial Clearing Agency, by, or on behalf of, the Trust. The Residual Interest
Instrument will be issued as a Definitive Trust Certificate. The certificate or
certificates delivered to DTC evidencing such Trust Certificates shall initially
be registered on the Certificate Register in the name of Cede & Co., the nominee
of the initial Clearing Agency, and no Certificate Owner will receive a
definitive certificate representing such Certificate Owner's interest in the
Trust Certificates, except as provided in Section 3.13. Unless and until
definitive, fully registered Trust Certificates (the "DEFINITIVE TRUST
CERTIFICATES") have been issued to Certificate Owners pursuant to Section 3.13:

               (i) the provisions of this Section shall be in full force and
        effect;

               (ii) the Depositor, the Servicer, the Certificate Registrar, the
        Owner Trustee and the Trust Agent, subject to the provisions and
        limitations of Sections 2.03 and 2.06, may deal with the Clearing Agency
        for all purposes (including the making of distributions on the Trust
        Certificates) as the authorized representative of the Certificate
        Owners;

               (iii) to the extent that the provisions of this Section conflict
        with any other provisions of this Agreement, the provisions of this
        Section shall control;

               (iv) the rights of Certificate Owners shall be exercised only
        through the Clearing Agency (or through procedures established by the
        Clearing Agency) and shall be limited to






                                      -13-
<PAGE>   18

        those established by law and agreements between such Certificate Owners
        and the Clearing Agency and/or the Clearing Agency Participants;
        pursuant to the Depository Agreement, unless and until Definitive Trust
        Certificates are issued pursuant to Section 3.13, the Clearing Agency
        will make book-entry transfers among the Clearing Agency Participants
        and receive and transmit distributions of principal and interest on the
        Certificates to such Clearing Agency Participants; and

               (v) whenever this Agreement requires or permits actions to be
        taken based upon instructions or directions of Holders of Certificates
        evidencing a specified percentage of the Percentage Interests thereof,
        the Clearing Agency shall be deemed to represent such percentage only to
        the extent that it has received instructions to such effect from
        Certificate Owners and/or Clearing Agency Participants owning or
        representing, respectively, such required percentage of the beneficial
        interest in Certificates and has delivered such instructions to the
        Owner Trustee or the Trust Agent.

        Section 3.12 Notices to Clearing Agency. Whenever notice or other
communication to the Certificateholders is required or desired to be given
hereunder, unless and until Definitive Trust Certificates shall have been issued

                   APPLICATION OF TRUST FUNDS; CERTAIN DUTIES

        Section 5.01 Establishment of Certificate Distribution Account. The
Trust Agent shall cause the Servicer, for the benefit of the Owners, to
establish and maintain an account denominated "CERTIFICATE DISTRIBUTION ACCOUNT
- - OT 1999-D, THE CHASE MANHATTAN BANK, TRUST AGENT," which account shall be an
Eligible Account (the "CERTIFICATE DISTRIBUTION ACCOUNT"). Funds shall be
deposited in the Certificate Distribution Account as provided in the Sale and
Servicing Agreement.

        All of the right, title and interest of the Trust Agent in all funds on
deposit from time to time in the Certificate Distribution Account and in all
proceeds thereof shall be held for the benefit of the Owners and such other
persons entitled to distributions therefrom. Except as otherwise expressly
provided herein or in the Sale and Servicing Agreement, the Certificate
Distribution Account shall be under the sole dominion and control of the Trust
Agent, as agent of the Owner Trustee, for the benefit of the Owners.

        The Certificate Distribution Account shall be subject to and established
and maintained in accordance with the applicable provisions of the Sale and
Servicing Agreement, including, without limitation, the provisions of Section
4.03(b) of the Sale and Servicing Agreement regarding distributions from the
Certificate Distribution Account.

        Section  5.02   Application of Trust Funds.

        (a) On each Distribution Date, the Trust Agent, on behalf of the Owner

Trustee, shall cause the Paying Agent to send to each Certificateholder and each
Residual Interestholder the statement or statements provided to the Owner
Trustee or the Trust Agent by the Servicer pursuant to Section 4.05 of the Sale
and Servicing Agreement with respect to such Distribution Date.

        (c) In the event that any withholding tax is imposed on the Trust's
payment (or allocations of income) to an Owner, such tax shall reduce the amount
otherwise distributable to the Owner in accordance with this Section. The Trust
Agent is hereby authorized and directed to retain from amounts otherwise
distributable to the Owners sufficient funds for the payment of any tax that is
legally owed by the Trust (but such authorization shall not prevent the Owner
Trustee or the Trust Agent from contesting any such tax in appropriate
proceedings, and withholding payment of such tax, if permitted by law, pending
the outcome of such proceedings). The amount of any withholding tax imposed with
respect to an Owner shall be treated as cash distributed to such Owner at the
time it is withheld by the Trust and remitted to the appropriate taxing
authority. If there is a possibility that withholding tax is payable with
respect to a distribution, the Trust Agent shall withhold such amounts in
accordance with this paragraph (c).

        Section 5.03 Method of Payment. Subject to Section 9.01(c) respecting
the final payment upon retirement of each Trust Certificate, distributions
required to be made to each Owner of record on the related Record Date shall be

relevant Certificateholder, by wire transfer of immediately available funds or
pursuant to other arrangements), the amount to be distributed to such Owner
pursuant to such Owner's Trust Certificates.

        Section 5.04 No Segregation of Monies; No Interest. Subject to Sections
5.01 and 5.02, monies received by the Trust Agent hereunder need not be
segregated in any manner except to the extent required by law or the Sale and
Servicing Agreement and may be deposited under such general conditions as may be
prescribed by law, and the Trust Agent shall not be liable for any interest
thereon.

        Section 5.05 Accounting and Reports to the Noteholders, Owners, the
Internal Revenue Service and Others. The Trust Agent shall (a) maintain (or
cause to be maintained) the books of the Trust on a calendar year basis and the
accrual method of accounting, (b) deliver to each Owner, as may be required by
the Code and applicable Treasury Regulations, such information as may be
required (including Schedule K-1) to enable each Owner to prepare its federal
and state income tax returns, (c) file such tax returns relating to the Trust
(including a partnership information return, IRS Form 1065) and make such
elections as from time to time may be required or appropriate under any
applicable state or federal statute or any rule or regulation thereunder so as
to maintain the Trust's characterization as a partnership for federal income tax
purposes, (d) cause such tax returns to be signed in the manner required by law
and (e) collect or cause to be collected any withholding tax as described in and
in accordance with Section 5.02(c) with respect to income or distributions to
Owners. Unless otherwise required by applicable law, the Trust Agent shall elect

discount that accrues with respect to the Contracts. The Trust Agent shall not
make the election provided under Section 754 of the Code.

        Section 5.06 Signature on Returns; Tax Matters Partner.

        (a) The Owner Trustee shall sign on behalf of the Trust the tax returns
of the Trust, unless applicable law requires an Owner to sign such documents, in
which case such documents shall be signed by the Depositor, as long as the
Depositor holds a Residual Interest Instrument, and otherwise the holder of the
largest Percentage Interest in the Residual Interest Instruments shall sign such
documents.

        (b) The Depositor shall be designated the "tax matters partner" of the
Trust pursuant to Section 6231(a)(7)(A) of the Code and applicable Treasury
Regulations, as long as the Depositor holds a Residual Interest Instrument, and
otherwise the owner of the largest Percentage Interest in the Residual Interest
Instruments shall be the "tax matters partner".

directed to execute and deliver on behalf of the Trust the Basic Documents to
which the Trust is to be a party and each certificate or other document attached
as an exhibit to or contemplated by the Basic Documents to which the Trust is to
be a party and any amendment or other agreement, as evidenced conclusively by
the Owner Trustee's execution thereof. In addition to the foregoing, the Owner
Trustee is authorized, but shall not be obligated, to take all actions required
of the Trust pursuant to the Basic Documents. The Owner Trustee is further
authorized from time to time to take such action as the Administrator recommends
with respect to the Basic Documents.

        Section 6.02 General Duties. Subject to the provisions and limitations
of Sections 2.03 and 2.06;

        (a) it shall be the duty of the Owner Trustee to discharge (or cause to
be discharged through the Administrator or such agents as shall be appointed
with the consent of the Insurer) all of its responsibilities pursuant to the
terms of this Agreement and the other Basic Documents to which the Trust is a
party and to administer the Trust in the interest of the Owners, subject to the
Basic Documents and in accordance with the provisions of this Agreement.
Notwithstanding the foregoing, the Owner Trustee shall be deemed to have
discharged its duties and responsibilities hereunder and under the other Basic
Documents to the extent the Administrator or the Trust Agent has agreed in the
Administration Agreement or this Agreement, respectively, to perform any act or
to discharge any duty of the Owner Trustee or the Trust hereunder or under any
Basic Document, and the Owner Trustee shall not be held liable for the default
or failure of the Administrator or the Trust Agent to carry out its obligations
under the Administration Agreement or this Agreement, respectively; and

        (b) it shall be the duty of the Trust Agent to discharge all of its
responsibilities pursuant to the terms of this Agreement and the other Basic
Documents to which the Trust and the Trust

Agent are a party and to administer the Trust in the interest of the Owners,
subject to the Basic Documents and in accordance with the provisions of this
Agreement.

        Section 6.03 Action Upon Instruction.

        (a) Subject to Article Four, in accordance with the terms of the Basic
Documents, the Owners may by written instruction direct the Owner Trustee or the
Trust Agent in the management of the Trust. Such direction may be exercised at
any time by written instruction of the Owners pursuant to Article Four.

        (b) Neither the Owner Trustee nor the Trust Agent shall be required to
take any action hereunder or under any other Basic Document if the Owner Trustee
or the Trust Agent, as applicable, shall have reasonably determined, or shall
have been advised by counsel, that such action is likely to result in liability
on the part of the Owner Trustee or the Trust Agent, as applicable, or is
contrary to the terms hereof or of any other Basic Document or is otherwise
contrary to law.

        (c) Whenever the Owner Trustee or the Trust Agent is unable to decide
between alternative courses of action permitted or required by the terms of this
Agreement or under any other Basic Document, the Owner Trustee or the Trust
Agent, as applicable, shall promptly give notice (in such form as shall be
appropriate under the circumstances) to the Owners and the Insurer requesting
instruction as to the course of action to be adopted, and to the extent the
Owner Trustee or the Trust Agent, as applicable, acts in good faith in
accordance with any written instruction of the Owners received, the Owner
Trustee or the Trust Agent, as applicable, shall not be liable on account of
such action to any Person. If the Owner Trustee or the Trust Agent shall not
have received appropriate instruction within ten days of such notice (or within
such shorter period of time as reasonably may be specified in such notice or may
be necessary under the circumstances) it may, but shall be under no duty to,
take or refrain from taking such action not inconsistent with this Agreement and
the other Basic Documents, as it shall deem to be in the best interests of the
Owners, and shall have no liability to any Person for such action or inaction.

        (d) In the event that the Owner Trustee or the Trust Agent is unsure as
to the application of any provision of this Agreement or any other Basic
Document or any such provision is ambiguous as to its application, or is, or
appears to be, in conflict with any other applicable provision, or in the event
that this Agreement permits any determination by the Owner Trustee or the Trust
Agent or is silent or is incomplete as to the course of action that the Owner
Trustee is required to take with respect to a particular set of facts, the Owner
Trustee or the Trust Agent may give notice (in such form as shall be appropriate
under the circumstances) to the Owners requesting instruction and, to the extent
that the Owner Trustee or the Trust Agent, as applicable, acts or refrains from
acting in good faith in accordance with any such instruction received, the Owner
Trustee or the Trust Agent, as applicable, shall not be liable, on account of
such action or inaction, to any Person. If the Owner Trustee or the Trust Agent
shall not have received appropriate instruction within ten days of such notice
(or within such shorter period of time as reasonably may be specified in such
notice or may be necessary under the circumstances) it may, but shall be under
no duty to, take or refrain from taking such action not inconsistent with this
Agreement or the other Basic Documents, as it shall deem to be in the best
interests of the Owners, and shall have no liability to any Person for such
action or inaction.

Instructions. Neither the Owner Trustee nor the Trust Agent shall have any duty
or obligation to manage, make any payment with respect to, register, record,
sell, dispose of or otherwise deal with the Trust Estate, or to otherwise take

contemplated hereby to which the Owner Trustee or the Trust Agent, as
applicable, is a party, except as expressly provided by the terms of this
Agreement or in any document or written instruction received by the Owner
Trustee or the Trust Agent, as applicable, pursuant to Section 6.03; and no
implied duties or obligations shall be read into this Agreement or any other
Basic Document against the Owner Trustee or the Trust Agent. Neither the Owner
Trustee nor the Trust Agent shall have any responsibility for filing any
financing or continuation statement in any public office at any time or to
otherwise perfect or maintain the perfection of any security interest or lien
granted to it hereunder or to prepare or file any Commission filing for the
Trust or to record this Agreement or any other Basic Document. Each of the Owner
Trustee and the Trust Agent nevertheless agrees that it will, at its own cost
and expense, promptly take all action as may be necessary to discharge any liens
on any part of the Trust Estate that result from actions by, or claims against,
the Owner Trustee or the Trust Agent, as applicable, that are not related to the
ownership or the administration of the Trust Estate or the Grant of any portion
thereof to the Indenture Trustee pursuant to the Indenture.

        Section 6.05 No Action Except Under Specified Documents or Instructions.
Neither the Owner Trustee nor the Trust Agent shall manage, control, use, sell,
dispose of or otherwise deal with any part of the Trust Estate except in
accordance with (i) the powers granted to and the authority conferred upon the
Owner Trustee or the Trust Agent, as applicable, pursuant to this Agreement,
(ii) the other Basic Documents and (iii) any document or instruction delivered
to the Owner Trustee or the Trust Agent, as applicable, pursuant to Section
6.03.

        Section 6.06 Restrictions. Neither the Owner Trustee nor the Trust Agent
shall take any action (i) that is inconsistent with the purposes of the Trust
set forth in Section 2.03 or (ii) that, to the actual knowledge of the Owner
Trustee or the Trust Agent, as applicable, would result in the Trust's becoming
taxable as a corporation for federal or state income tax purposes. The Owners
shall not direct the Owner Trustee or the Trust Agent to take action that would
violate the provisions of this Section.

        Agreement, nor the consummation by it of the transactions contemplated
        hereby nor compliance by it with any of the terms or provisions hereof
        will contravene any federal or Delaware law, governmental rule or
        regulation governing the banking or trust powers of the Owner Trustee or
        any judgment or order binding on it, or constitute any default under its
        charter documents or bylaws or, to its actual knowledge, any indenture,
        mortgage, contract, agreement or instrument to which it is a party or by
        which any of its properties may be bound or result in the creation or
        imposition of any lien, charge or encumbrance on the Trust Estate

or with respect to the sufficiency of the Trust Estate or its ability to
generate the payments to be distributed to Certificateholders and Residual
Interestholders under this Agreement or the Noteholders under the Indenture,
including, without limitation, the existence, condition and ownership of any
Financed Vehicle; the existence and enforceability of any insurance thereon; the

the validity of the assignment of any Contract to the Trust or of any
intervening assignment; the completeness of any Contract; the performance or
enforcement of any Contract; the compliance by the Depositor, the Insurer or the

Article Five and (ii) the expiration of 21 years from the death of the survivor
of the descendants of Joseph P. Kennedy, the late Ambassador of the United
States to the Court of St. James's, living on the date hereof. The bankruptcy,
liquidation, dissolution, death or incapacity of any Owner shall not (i) operate
to terminate this Agreement or the Trust, (ii) entitle such Owner's legal
representatives or heirs to claim an accounting or to take any action or

        (c) Notice of any termination of the Trust, specifying the Distribution
Date upon which Certificateholders shall surrender their Certificates to the
Paying Agent for payment of the final distribution and cancellation, shall be
given by the Trust Agent by letter to Certificateholders mailed within five
Business Days of receipt of notice of such termination from the Servicer given
pursuant to Section 8.01(b) of the Sale and Servicing Agreement, stating (i) the
Distribution Date upon or with respect to which final payment of the
Certificates shall be made upon presentation and surrender of the Certificates
at the office of the Paying Agent in the City of New York therein designated,
(ii) the amount of any such final payment and (iii) that the Record Date
otherwise applicable to such Distribution Date is not applicable, payments being
made only upon presentation and surrender of the Certificates at the office of
the Paying Agent therein specified. The Trust Agent shall give such notice to
the Certificate Registrar (if other than the Trust Agent) and the Paying Agent
(if other than the Trust Agent) at the time such notice is given to
Certificateholders. Upon presentation and surrender of the Certificates, the
Paying Agent shall cause to be distributed to Certificateholders amounts
distributable on such Distribution Date pursuant to Section 5.02. In addition,
the Trust Agent shall notify the Rating Agencies upon the final payment of the
Certificates.

        (d) In the event that all of the Certificateholders shall not surrender
their Certificates for cancellation within six months after the date specified
in the above-mentioned written notice, the Trust Agent shall give a second
written notice to the remaining Certificateholders to surrender their Trust
Certificates for cancellation and receive the final distribution with respect
thereto. If within one year after the second notice all the Certificates shall
not have been surrendered for cancellation, the Trust Agent may take appropriate
steps, or may appoint an agent to take appropriate steps, to contact the
remaining Certificateholders concerning surrender of their Certificates, and the
cost thereof shall be paid out of the funds and other assets that shall remain
subject to this Agreement. Any funds remaining in the Trust after exhaustion of
such remedies shall be distributed by the Trust Agent to the Residual
Interestholders on a pro rata basis.

                             TRUSTEE AND TRUST AGENT

        Section 10.01 Eligibility Requirements for Owner Trustee. The Owner
Trustee shall at all times be a corporation satisfying the provisions of Section
3807(a) of the Business Trust Statute; authorized to exercise corporate trust
powers; having a combined capital and surplus of at least $50,000,000 and
subject to supervision or examination by federal or state authorities; and
having (or having a parent that has) a rating of at least Baa3 by Moody's and
A-1 by Standard & Poor's. If such corporation shall publish reports of condition
at least annually pursuant to law or to the requirements of the aforesaid
supervising or examining authority, then for the purpose of this Section, the
combined capital and surplus of such corporation shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published. In case at any time the Owner Trustee shall cease to be eligible
in accordance with the provisions of this Section, the Owner Trustee shall
resign immediately in the manner and with the effect specified in Section 10.02.

        Section 10.02 Resignation or Removal of Owner Trustee. The Owner Trustee
may at any time resign and be discharged from the trusts hereby created by
giving written notice thereof to the Administrator and the Insurer. Upon
receiving such notice of resignation, the Administrator shall promptly appoint a
successor Owner Trustee by written instrument, in duplicate, one copy of which
instrument shall be delivered to the resigning Owner Trustee and one copy to the
successor Owner Trustee; provided that the Depositor and the Insurer shall have
received written confirmation from each Rating Agency that the proposed
appointment will not result in an increased capital charge to the Insurer by
either Rating Agency. If no successor Owner Trustee shall have been so appointed
and have accepted appointment within 30 days after the giving of such notice of
resignation, the resigning Owner Trustee or the Insurer may petition any court
of competent jurisdiction for the appointment of a successor Owner Trustee.

        If at any time the Owner Trustee shall cease to be eligible in
accordance with the provisions of Section 10.01 and shall fail to resign after
written request therefor by the Administrator or the Insurer, or if at any time
the Owner Trustee shall be legally unable to act, or shall be adjudged bankrupt
or insolvent, or a receiver of the Owner Trustee or of its property shall be
appointed, or any public officer shall take charge or control of the Owner
Trustee or of its property or affairs for the purpose of rehabilitation,
conservation or liquidation, or if at any time the Owner Trustee shall have
breached any representation or warranty contained in Section 7.03(a)(iii)
(without regard to any knowledge qualification), then the Administrator or the
Insurer may remove the Owner Trustee. If the Owner Trustee shall be removed
under the authority of the immediately preceding sentence, the Administrator
shall promptly appoint a successor Owner Trustee acceptable to the Insurer by
written instrument, in duplicate, one copy of which instrument shall be
delivered to the outgoing Owner Trustee so removed and one copy to the successor
Owner Trustee, and shall pay all fees owed to the outgoing Owner Trustee.

        Any resignation or removal of the Owner Trustee and appointment of a
successor Owner Trustee pursuant to any of the provisions of this Section shall
not become effective until acceptance of appointment by the successor Owner
Trustee pursuant to Section 10.03 and payment of all fees and expenses owed to
the outgoing Owner Trustee. The Administrator shall provide notice of such
resignation or removal of the Owner Trustee to each Rating Agency.

        Section 10.03 Successor Owner Trustee. Any successor Owner Trustee
appointed pursuant to Section 10.02 shall execute, acknowledge and deliver to
the Administrator, the Insurer and to its predecessor Owner Trustee an
instrument accepting such appointment under this Agreement, and thereupon the
resignation or removal of the predecessor Owner Trustee shall become effective,
and such successor Owner Trustee, without any further act, deed or conveyance,
shall become fully vested with all the rights, powers, duties and obligations of
its predecessor under this Agreement, with like effect as if originally named as
Owner Trustee. The predecessor Owner Trustee shall upon payment of its fees and
expenses deliver to the successor Owner Trustee all documents and statements and
monies held by it under this Agreement; and the Administrator and the
predecessor Owner Trustee shall execute and deliver such instruments and do such
other things as may reasonably be required for fully and certainly vesting and
confirming in the successor Owner Trustee all such rights, powers, duties and
obligations.

        No successor Owner Trustee shall accept appointment as provided in this
Section unless at the time of such acceptance such successor Owner Trustee shall
be eligible pursuant to Section 10.01.

        Upon acceptance of appointment by a successor Owner Trustee pursuant to
this Section, the Administrator shall mail notice thereof to all Owners, the
Insurer, the Depositor, the Servicer, the Indenture Trustee, the Noteholders and
each Rating Agency. If the Administrator shall fail to mail such notice within
ten days after acceptance of such appointment by the successor Owner Trustee,
the successor Owner Trustee shall cause such notice to be mailed at the expense
of the Administrator.

        Section 10.04 Merger or Consolidation of Owner Trustee. Any corporation
into which the Owner Trustee may be merged or converted or with which it may be
consolidated, or any corporation resulting from any merger, conversion or
consolidation to which the Owner Trustee shall be a party, or any corporation
succeeding to all or substantially all of the corporate trust business of the
Owner Trustee, shall be the successor of the Owner Trustee hereunder, without
the execution or filing of any instrument or any further act on the part of any
of the parties hereto, anything herein to the contrary notwithstanding;
provided, that such corporation shall be eligible pursuant to Section 10.01 and,
provided, further, that the Owner Trustee shall mail notice of such merger or
consolidation to each Rating Agency.

        Section 10.05 Appointment of Co-Trustee or Separate Trustee.
Notwithstanding any other provisions of this Agreement, at any time, for the
purpose of meeting any legal requirements of any jurisdiction in which any part
of the Trust Estate or any Financed Vehicle may at the time be located, the
Administrator and the Owner Trustee acting jointly shall have the power and
shall execute and deliver all instruments to appoint one or more Persons
approved by the Administrator, the Insurer and Owner Trustee to act as
co-trustee, jointly with the Owner Trustee, or as separate trustee or separate
trustees, of all or any part of the Trust Estate, and to vest in such Person, in
such capacity, such title to the Trust or any part thereof and, subject to the
other provisions of this Section, such






                                      -30-

powers, duties, obligations, rights and trusts as the Administrator and the
Owner Trustee may consider necessary or desirable. If the Administrator shall
not have joined in such appointment within 15 days after the receipt by it of a
request so to do, the Owner Trustee and the Insurer shall have the power to make
such appointment. No co-trustee or separate trustee under this Agreement shall
be required to meet the terms of eligibility as a successor Owner Trustee,
provided that such co-trustee or successor trustee must be acceptable to the
Rating Agencies and no notice of the appointment of any co-trustee or separate
trustee shall be required pursuant to Section 10.03.

        Section 10.06 Appointment of Trust Agent. Each separate trustee and
co-trustee shall, to the extent permitted by law, be appointed and act subject
to the following provisions and conditions:

        (a) all rights, powers, duties and obligations conferred or imposed upon
the Owner Trustee shall be conferred upon and exercised or performed by the
Owner Trustee and such separate trustee or co-trustee jointly (it being
understood that such separate trustee or co-trustee is not authorized to act
separately without the Owner Trustee joining in such act), except to the extent
that under any law of any jurisdiction in which any particular act or acts are
to be performed, the Owner Trustee shall be incompetent or unqualified to
perform such act or acts, in which event such rights, powers, duties and
obligations (including the holding of title to the Trust Estate or any portion
thereof in any such jurisdiction) shall be exercised and performed singly by
such separate trustee or co-trustee, but solely at the direction of the Owner
Trustee;

        (b) no trustee under this Agreement shall be personally liable by reason
of any act or omission of any other trustee under this Agreement; and

        (c) the Administrator, the Insurer and the Owner Trustee acting jointly
may at any time accept the resignation of or remove any separate trustee or
co-trustee.

        Any notice, request or other writing given to the Owner Trustee shall be
deemed to have been given to each of the then separate trustees and co-trustees,
as effectively as if given to each of them. Every instrument appointing any
separate trustee or co-trustee shall refer to this Agreement and the conditions
of this Article. Each separate trustee and co-trustee, upon its acceptance of
the trusts conferred, shall be vested with the estates or property specified in
its instrument of appointment, either jointly with the Owner Trustee or
separately, as may be provided therein, subject to all the provisions of this
Agreement, specifically including every provision of this Agreement relating to
the conduct of, affecting the liability of or affording protection to, the Owner
Trustee. Each such instrument shall be filed with the Owner Trustee and a copy
thereof given to the Administrator and the Insurer.

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

        The Owner Trustee on behalf of the Trust hereby appoints The Chase
Manhattan Bank as Trust Agent for the purpose of establishing and maintaining
the Certificate Distribution Account and making the distributions therefrom to
the persons entitled thereto pursuant to Section 4.03 of the






                                      -31-

Sale and Servicing Agreement and for purposes of performing the other duties
specified to be performed by the Trust Agent under this Agreement and the other
Basic Documents. The Owner Trustee and the Trust Agent each agree that upon the
occurrence and continuation of an Insurer Default, the Trust Agent shall resign
and the Owner Trustee shall assume all rights, duties and obligations of the
Trust Agent under the Sale and Servicing Agreement and this Agreement, including
without limitation, the obligations of the Trust Agent pursuant to Sections
3.02, 3.03, 3.04, 3.05, 3.07, 3.08, 3.09, 3.10, 5.01 and 5.02 hereof. The Trust
Agent, in its capacity as Trust Agent, shall not have any rights, duties or
obligations except as expressly provided in this Agreement and the Sale and
Servicing Agreement.

                                  MISCELLANEOUS

        Section 11.01 Supplements and Amendments.

        (a) This Agreement may be amended by the Depositor, the Owner Trustee
and the Trust Agent, with the prior written consent of the Insurer, but without
the consent of any of the Noteholders or the Owners, to cure any ambiguity, to
correct or supplement any provisions herein which may be inconsistent with any
of the provisions herein or make any other provisions with respect to matters or
questions arising hereunder that shall not be inconsistent with the provisions
of this Agreement; provided, however, that (i) any such action shall not
materially and adversely affect the interests of any Noteholder or any Owner;
(ii) any such action shall be deemed not to materially and adversely affect the
interest of any Noteholder or Certificateholder if the Person requesting the
amendment obtains (A) a letter from each Rating Agency to the effect that the
amendment would not result in a downgrading or withdrawal of the ratings then
assigned to the Notes and Certificates by such Rating Agency or (B) an opinion
of counsel to such effect; and (iii) any such action shall be deemed not to
materially and adversely affect the interest of any Residual Interestholder if
the Person requesting such amendment obtains an opinion of counsel to such
effect, or Residual Interestholders representing 100% of the Percentage
Interests consent to such amendment.

        (b) Subject to Section 11.14, this Agreement may also be amended from
time to time with the prior written consent of the Insurer by the Depositor, the
Owner Trustee and the Trust Agent, with the consent of (i) for so long as the
Notes are Outstanding, Noteholders representing not less than 51% of the
Outstanding Amount acting together as a single class, and (ii) if no Notes are
Outstanding, the Holders of Certificates evidencing not less than 51% of the
Certificate Balance (which consent of any Holder of a Note or Certificate given
pursuant to this Section or pursuant to any other provision of this Agreement
shall be conclusive and binding on such Holder and on all future Holders of such
Note or Certificate, as the case may be, issued upon the transfer thereof or in
exchange thereof or in lieu thereof whether or not notation of such consent is
made thereon) and, if such amendment materially and adversely affects the
interests of the Residual Interestholders, with the consent of Residual
Interestholders evidencing not less than 51% of the Percentage Interests, for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of this Agreement, or of modifying in any manner the
rights of the Noteholders or the Owners; provided, however, that no such
amendment may (i) increase or reduce in any manner the amount of, or accelerate
or delay the timing of, collections of payments on Contracts or distributions






                                      -32-

that shall be required to be made for the benefit of the Noteholders, the
Certificateholders or Residual Interestholders or (ii) reduce the aforesaid
percentage of the Outstanding Amount of the Notes and the Certificate Balance or
Percentage Interest of the Residual Interestholders required to consent to any
such amendment, without the consent of the Holders of all outstanding Notes,
Certificates and Residual Interest Instruments.

        (c) Prior to the execution of any such amendment or consent, the Owner
Trustee shall furnish written notification of the substance of such amendment or
consent, together with a copy thereof, to the Indenture Trustee, the Insurer,
the Administrator and each Rating Agency.

        (d) Promptly after the execution of any such amendment or consent, the
Trust Agent shall furnish written notification of the substance of such
amendment or consent to each Owner. It shall not be necessary for the consent of
Certificateholders, Residual Interestholders, Noteholders or the Indenture
Trustee pursuant to this Section to approve the particular form of any proposed
amendment or consent, but it shall be sufficient if such consent shall approve
the substance thereof. The manner of obtaining such consents (and any other
consents of Owners provided for in this Agreement or in any other Basic
Document) and of evidencing the authorization of the execution thereof by Owners
shall be subject to such reasonable requirements as the Owner Trustee may
prescribe.

        (e) Promptly after the execution of any amendment to the Certificate of
Trust, the Owner Trustee shall cause the filing of such amendment with the
Secretary of State.

        (f) In connection with the execution of any amendment to this Agreement
or any other Basic Document to which the Issuer is a party and for which
amendment the Owner Trustee's consent is sought, each of the Owner Trustee and
the Trust Agent shall be entitled to receive and conclusively rely upon an
Opinion of Counsel to the effect that such amendment is authorized or permitted
by the Basic Documents and that all conditions precedent in the Basic Documents
for the execution and delivery thereof by the Issuer, the Owner Trustee or the
Trust Agent, as the case may be, have been satisfied. The Owner Trustee and the
Trust Agent may, but shall not be obligated to, enter into any such amendment
that affects the Owner Trustee's or the Trust Agent's own rights, duties or
immunities under this Agreement or otherwise.

Person any legal or equitable right, remedy or claim in the Trust Estate or

contained herein.

         "SIMPLE INTEREST CONTRACT" means a Contract as to which the portion of
payments allocable to earned interest and principal thereunder is determined
according to the Simple Interest Method. For such Contracts, interest accrued as
of the Due Date is paid first, and then the remaining payment is applied to the
unpaid principal balance. Accordingly, if an Obligor pays the fixed monthly
installment in advance of the Due Date, the portion of the payment allocable to
interest for the period since the preceding payment will be less than it would
be if the payment were made on the Due Date, and the portion of the payment
allocable to reduce the principal balance will be correspondingly greater.
Conversely, if an Obligor pays the fixed monthly installment after its Due Date,
the portion of the payment allocable to interest for the period since the
preceding payment will be greater than it would be if the payment were made on
the Due Date, and the portion of the payment allocable to reduce the principal
balance will be correspondingly smaller. When necessary, an adjustment will be
made at the maturity of the Contract to the scheduled final payment to reflect
the larger or smaller, as the case may be, allocations of payments to the amount
financed under the Contract as a result of early or late payments, as the case
may be.

         "SIMPLE INTEREST METHOD" means the method for calculating interest on a
Contract whereby interest due is calculated each day based on the actual

                                   the Purchase Agreement, to cause Onyx as
                                   seller thereunder to repurchase Prefunded
                                   Contracts listed on any Transfer Certificate
                                   under certain circumstances;

                           (vi)    any and all security interests of the Seller
                                   in the related Financed Vehicles and the
                                   rights to receive proceeds from claims on
                                   certain insurance policies covering such
                                   Financed Vehicles or the individual Obligors
                                   under each related Prefunded Contract;

                           (vii)   the Seller's right to proceeds under the
                                   Blanket Insurance Policy with respect to the
                                   Prefunded Contracts; and

                           (viii)  all proceeds in any way delivered with
                                   respect to the foregoing, all rights to
                                   payments with respect to the foregoing and
                                   all rights to enforce the foregoing.

         The foregoing items of property listed in Sections 2.01(a) and (b),
together with the rights of the Indenture Trustee under the Policy, are
collectively referred to as the "TRUST PROPERTY". In addition, on or prior to
the Closing Date, the Seller shall cause the Insurer to deliver the Policy to
the Indenture Trustee for the benefit of the Securityholders.

         It is the intention of the Seller and the Issuer that the assignment
and transfer herein contemplated constitute (and shall be construed and treated
for all purposes as) a true and complete sale of the Trust Property (other than
the Spread Account and the Policy), conveying good title thereto free and clear
of any liens and encumbrances, from the Seller to the Issuer. However, in the
event that such conveyance is deemed to be a pledge to secure a loan (in spite
of the express intent of the parties hereto that this conveyance constitutes,
and shall be construed and treated for all purposes, as a true and complete
sale), the Seller hereby grants to the Issuer, for the benefit of the
Securityholders and the Insurer, a first priority perfected security interest in
all of the Seller's right, title and interest in the Trust Property whether now
existing or hereafter created and all proceeds of the foregoing to secure the
loan deemed to be made in connection with such pledge and, in such event, this
Agreement shall constitute a security agreement under applicable law.

         (c) The sale and assignment of the Prefunded Contracts and the other
property and rights related thereto described in Section 2.01(b) shall be
subject to the satisfaction of each of the following conditions, as well as the
conditions set forth in Section 4.08, as of the related Prefunding Transfer
Date, as applicable:

                           (i)     the Seller shall have delivered to the
                                   Custodian, on behalf of the Issuer, the
                                   Prefunded Contracts, and the Seller shall
                                   have delivered to

                                   Servicer and the Seller, respectively, were
                                   not insolvent nor were they made insolvent by
                                   such transfer nor were they aware of any such
                                   pending insolvency;

                                   such Prefunded Contracts will not result in a
                                   material adverse tax consequence to the
                                   Issuer or the Securityholders;

                           (iv)    the Funding Period shall not have terminated;

                                   or the Servicer to be adverse to the
                                   interests of the Securityholders or the
                                   Insurer shall have been utilized in selecting
                                   the Prefunded Contracts;

                           (vi)    the Seller and the Insurer shall not have
                                   been advised by either Rating Agency on or

                                   such Prefunding Transfer Date that the
                                   conveyance of the Prefunded Contracts would
                                   result in a qualification, modification or
                                   withdrawal of its then current rating of the
                                   Securities without regard to the Policy;

                           (x)     within three Business Days prior to each
                                   Prefunding Transfer Date, the Seller shall

                                   payment is due under each such Prefunded
                                   Contract) relating to the Prefunded Contracts

                                   Agencies and the Insurer with respect to the
                                   Funded Contracts, and, as of the related
                                   Prefunding Cut-Off Date, shall have certified
                                   that the information contained therein is
                                   true and correct.

         (d) As of the Closing Date, the Issuer acknowledges the conveyance to
it of the Trust Property from the Seller, including all right, title and
interest of the Seller in and to the Trust Property, receipt of which is hereby
acknowledged by the Issuer. Concurrently with such delivery and in exchange
therefor, the Issuer has pledged to the Indenture Trustee, for the benefit of
the Securityholders and the Insurer, the Trust Property and the Indenture
Trustee, pursuant to the written instructions of the Issuer, has executed and
caused to be authenticated and delivered the Notes to the Seller or its
designee, upon the order of the Issuer. In addition, concurrently with such
delivery and in exchange therefor, the Owner Trustee, pursuant to the
instructions of the Seller, has executed (not in its individual capacity, but
solely as Owner Trustee on behalf of the Issuer) and caused to be authenticated
and delivered the Certificates to the Seller or its designee, upon the order of
the Seller.

         (e) In connection with the sale of the Contracts pursuant to the
Purchase Agreement, Onyx has filed with the office of the Secretary of State of
the State of California a UCC-1 financing statement naming Onyx as debtor,
naming the Seller as secured party and including the Contracts in the
description of the collateral. In connection with the sale of the Contracts
pursuant to this Agreement, the Seller has filed or caused to be filed with the
Secretary of State of the State of California a UCC-1 financing statement naming
the Seller as debtor, naming the Issuer as secured party, naming the Indenture
Trustee, on behalf of the Noteholders, as assignee, and including the Contracts
in the description of the collateral. In connection with the pledge of the
Contracts pursuant to the Indenture, the Trust has filed with the offices of the
Secretary of State of the State of Delaware UCC-1 financing statements naming
the Trust as debtor and the Indenture Trustee, on behalf of the Noteholders and
the Insurer, as secured party. The grant of a security interest to the Indenture
Trustee and the rights of the Indenture Trustee in the Contracts shall be
governed by the Indenture.

         The Seller shall have caused UCC-2 termination statements to have been
filed with the office of Secretary of State of the State of California
terminating any effective UCC-1 financing statements with respect to any
outstanding security interests in the Contracts.

         (f) From time to time, the Servicer shall cause to be taken such
actions as are necessary to continue the perfection of the respective interests
of the Trust and the Indenture Trustee in the Contracts and to continue the
first priority security interest of the Indenture Trustee in the Financed
Vehicles and their proceeds (other than, as to such priority, any statutory lien
arising by operation of law after the Closing Date which is prior to such
interest), including, without limitation, the filing of financing statements,
amendments thereto or continuation statements and the making of notations on
records or documents of title.

         (g) If any change in the name, identity or corporate structure of the
Seller or Onyx or the relocation of the chief executive office of either of them
would make any financing or continuation statement or notice of lien filed under
this Agreement or the other Basic Documents misleading within the meaning of
applicable provisions of the UCC or any title statute, the Servicer, within the
time period required by applicable law, shall file such financing statements or
amendments as may be required to preserve and protect the interests of the
Trust, the Indenture Trustee, the Securityholders and the Insurer in the
Contracts, the related Financed Vehicles and the proceeds thereof. Promptly
thereafter, the Servicer shall deliver to the Trust, the Indenture Trustee and
the Insurer an Opinion of Counsel stating that, in the opinion of such counsel,
all financing statements or amendments necessary fully to preserve and protect
the interests of the Trust, the Indenture Trustee, the Securityholders and the
Insurer in the Contracts, the related Financed Vehicles and the proceeds thereof
have been filed, and reciting the details of such filings.

         (h) During the term of this Agreement, the Seller and Onyx shall each
maintain its chief executive office in one of the states of the United States.

         (i) The Servicer shall pay all reasonable costs and disbursements in
connection with the perfection and the maintenance of perfection, as against all
third parties, of the Indenture Trustee's right, title and interest in and to

interest (subject to the security interest of the Insurer pursuant to the
Insurance Agreement) in the Financed Vehicles and the proceeds thereof.

                                   creditor of the Seller confirming that such
                                   creditor has no claim of any security
                                   interest in any of the Prefunded Contracts
                                   transferred during the Funding Period;

                           (ii)    deliver to each Rating Agency, the Insurer
                                   and the Indenture Trustee a Prefunding

                                   Counsel with respect to the absence of
                                   negative tax consequences to the Trust, the
                                   characterization of the transfer of the
                                   Prefunded Contracts and the perfection of the
                                   Indenture Trustee's interest on behalf of the
                                   Securityholders;

                           (iv)    deliver to each Rating Agency, the Insurer
                                   and the Indenture Trustee with respect to any

                                   more of the Contracts (including the
                                   Prefunded Contracts), by Outstanding
                                   Principal Balance, were originated, an
                                   opinion with respect to the perfection of the
                                   security interest of the Indenture Trustee in
                                   the Financed Vehicles securing the Contracts
                                   originated in such state; and

                           (v)     deliver to the Insurer an Opinion of Counsel
                                   to the effect that Onyx is duly qualified as
                                   a foreign corporation to do business, and is

                                   originated.

         Failure to comply with any of the conditions set forth in this Section
2.01(j) on the Prefunding Closing Date shall be deemed to be a breach of a

                                   all of the provisions of such insurance
                                   policy applicable to it so long as such

                           (xiv)   As of the related Prefunding Transfer Date,
                                   (a) such Contract will require that the

                                   comprehensive and collision insurance policy
                                   (i) in an amount at least equal to the lesser
                                   of (x) its maximum insurable value or (y) the
                                   principal amount due from the related
                                   Obligor(s) under such Contract, (ii) naming
                                   Onyx or a subsidiary of Onyx as a loss payee

                                   the Servicer shall have put in place a

                                   providing coverage upon repossession of the
                                   related Financed Vehicle in an amount equal
                                   to the lesser of the actual cash value of
                                   such Financed Vehicle, the cost of repair or
                                   replacement for such Financed Vehicle and the
                                   unpaid balance of the related Contract. Each
                                   of Onyx and the Seller shall, and Onyx shall
                                   cause any subsidiary of Onyx which originated
                                   a Contract to, at all times comply with all
                                   of the provisions of such insurance policies
                                   applicable to it.

                           (xv)    Such Contract was either originated by a
                                   subsidiary of Onyx, purchased by a subsidiary
                                   of Onyx, or acquired by Onyx from a Dealer
                                   with which it ordinarily does business, and
                                   no adverse selection procedures have been
                                   utilized in selecting such Contract from all
                                   other similar contracts purchased or
                                   originated by Onyx or any such subsidiary.

                           (xvi)   Payments under such Contract have been
                                   applied in accordance with Rule of 78's
                                   Method, the Actuarial Method or the Simple
                                   Interest Method, as provided in the
                                   applicable Contract, and are due monthly in
                                   substantially equal amounts through its
                                   Maturity Date sufficient to fully amortize
                                   the principal balance of such Contract by its
                                   Maturity Date.

                           (xvii)  There is only one original of such Contract
                                   and such original, together with all other

                                   the Custodian.

                           (xviii) As of the related Prefunding Transfer Date,
                                   the Servicer has clearly marked its
                                   electronic records to indicate that such
                                   Contract is then owned by the Issuer.

                           (xix)   At the date of origination of the Contract,
                                   the original principal balance of such
                                   Contract was not greater than the purchase
                                   price to the related Obligor(s) (including
                                   taxes, warranties, licenses and related
                                   charges) of the related Financed Vehicle.

                           (xx)    As of the related Prefunding Cut-Off Date,
                                   the Seller has not received notice that any
                                   Obligor under such Contract has filed for
                                   bankruptcy.

                           (xxi)   Such Contract has an original maturity of not
                                   more than 72 months, and as of the related
                                   Prefunding Cut-Off Date, such Contract has a
                                   remaining maturity of 72 months or less.

                           (xxii)  As of the related Prefunding Cut-Off Date,
                                   such Contract has a remaining principal
                                   balance of at least $500.

                           (xxiii) As of the related Prefunding Cut-Off Date,
                                   such Contract is secured by a Financed
                                   Vehicle that has not been repossessed without
                                   reinstatement.

                           (xxiv)  The Obligor on such Contract is either (a) a
                                   natural person residing in any state or (b)
                                   another entity, provided that a natural
                                   person is a joint and several Obligor with
                                   respect to such Contract.

                           (xxv)   No more than 50% of the Prefunded Contracts
                                   transferred to the Issuer as of any
                                   Prefunding Transfer Date shall be originated
                                   in any one state.

         (e) None of the foregoing representations and warranties shall be
construed as, and the Seller is specifically not making, any representations and
warranties regarding the collectibility of the Contracts or the future
performance of the Contracts.

         (f) The Seller has not prepared any financial statement which accounts
for the transfer of the Trust Property (other than the Policy and the Spread
Account) hereunder to the Issuer in any manner other than as a sale of the Trust
Property (other than the Policy and the Spread Account ) by it to the Issuer,
and the Seller has not in any other non-income tax respect (including, but not
limited to, for accounting purposes) accounted for or treated the transfer of
the Trust Property (other than the Policy and the Spread Account) hereunder in
any manner other than as a sale and absolute assignment to the Issuer of the
Seller's full right, title and ownership interest in the Trust Property (other
than the Policy and the Spread Account) to the Issuer.

         SECTION 2.03. REPURCHASE OF CERTAIN CONTRACTS.

         The representations and warranties of the Seller set forth in Section
2.02 with respect to each Contract and each of the conditions set forth in
Section 2.01(c) with respect to each transfer of Prefunded Contracts and Section
2.01(j) with respect to the Prefunding Closing Date and sale of Prefunded
Contracts shall survive delivery of the Contract Documents and shall continue
until the termination of this Agreement. Upon discovery by the Seller, the
Servicer, the Insurer or a Responsible Officer of the Owner Trustee, the
Indenture Trustee or the Trust Agent that any of such representations and
warranties was incorrect or that any of such conditions was unsatisfied as of
the time made or that any of the Contract Documents relating to any such
Contract has not been properly executed by the Obligor or contains a material
defect or has not been received by the Custodian, such Person making such
discovery shall give prompt notice to the other such Persons. If any such
defect, incorrectness or omission materially and adversely affects the interest
of the Noteholders, the Certificateholders, the Indenture Trustee, the Issuer or
the Insurer, the Seller shall cure the defect or eliminate or otherwise cure the
circumstances or condition in respect of which such representation or warranty
was incorrect as of the time made; provided that if the Seller is unable to do
so by the last day of the Collection Period following the Collection Period (or,
if the Seller elects, the last day of such Collection Period) during which the
Seller becomes aware of or receives written notice from the Servicer, the
Insurer or the Indenture Trustee of such defect, incorrectness or omission, it
shall repurchase such Contract on the last day of the applicable Collection
Period from the Issuer at the Purchase Amount. Upon any such repurchase, the
Issuer shall execute and deliver such instruments of transfer or assignment, in
each case without recourse, as shall be necessary to vest in the Seller any
Contract purchased hereunder. The sole remedy of the Issuer, the Indenture
Trustee or the Securityholders with respect to a breach of the Seller's
representations and warranties pursuant to Section 2.02 shall be to require the
Seller to repurchase Contracts pursuant to this Section; provided, however, that
the Seller shall indemnify the Owner Trustee, the Trust Agent, the Indenture
Trustee, the Insurer, the Issuer and the Securityholders against all costs,
expenses, losses, damages, claims and liabilities, including reasonable fees and
expenses of counsel, which may be asserted against or incurred by any of them as
a result of third-party claims arising out of the events or facts giving rise to
such breach.

         SECTION 2.04. CUSTODY OF CONTRACT FILES.

         (a) Duties of Custodian. The Custodian shall:

                           (i)      maintain continuous custody of the Contract
                                    Documents in secure and fire resistant
                                    facilities in accordance with customary
                                    standards for such custody. Such Contract
                                    Documents shall not be segregated to show
                                    the Issuer as owner thereof and the
                                    Indenture Trustee as the pledgee thereof,
                                    unless the Insurer requires such
                                    segregation.

                           (ii)     with respect to the Contract Documents, (A)
                                    act exclusively as the Custodian for the
                                    benefit of the Indenture Trustee and (B)
                                    hold all Contract Documents for the
                                    exclusive use (notwithstanding Sections
                                    2.04(a)(iii) and 2.04(a)(iv) below) and for
                                    the benefit of the Indenture Trustee.



                                      -38-
<PAGE>   43

                           (iii)    in the event that the Servicer is not the
                                    Custodian, to the extent the Servicer
                                    directs the Custodian in writing, deliver
                                    certain specified Contract Documents to the
                                    Servicer to enable the Servicer to service
                                    the Contracts pursuant to this Agreement. At
                                    such time as the Servicer returns such
                                    Contract Documents to the Custodian, the
                                    Servicer shall provide written notice of
                                    such return to the Custodian. The Custodian
                                    shall acknowledge receipt of the returned
                                    materials by signing the Servicer's notice
                                    and shall promptly send copies of such
                                    acknowledgment or receipt to the Servicer.

                           (iv)     upon reasonable prior written notice, permit
                                    the Servicer, the Indenture Trustee and the
                                    Insurer to examine the Contract Documents in
                                    the possession, or under the control, of the
                                    Custodian.

                           (v)      at its own expense, maintain at all times
                                    while acting as Custodian, and keep in full
                                    force and effect (A) fidelity insurance, (B)
                                    theft of documents insurance, (C) fire
                                    insurance, and (d) forgery insurance. All
                                    such insurance shall be in amounts, with
                                    standard coverage and subject to
                                    deductibles, as are customary for similar
                                    insurance typically maintained by banks that
                                    act as custodian in similar transactions.

         (b) Appointment of Custodian. As of the Closing Date, Onyx shall be the
Custodian of the Contract Documents; provided, however, that (i) the Indenture
Trustee (if the Notes have not been paid in full and the Indenture has not been
satisfied and discharged) and the Issuer, with the consent of the Insurer, or
(ii) the Insurer, may terminate such appointment at any time, with or without
cause by written notice to the Custodian, and upon the execution by the
Indenture Trustee at the direction of the Insurer (or, if the Notes have been
paid in full and the Indenture has been satisfied and discharged, the Issuer at
the direction of the Insurer) of a letter agreement substantially in the form of
Exhibit A attached hereto (the "APPOINTMENT OF CUSTODIAN"), revocably appointing
such other entity acceptable to the Insurer as agent of and bailee for the
Indenture Trustee (or, if applicable, the Trust) to act as Custodian (the
"SUCCESSOR CUSTODIAN") of the Contract Documents, such Successor Custodian shall
be so appointed and shall from the effective date of such Appointment of
Custodian retain custody of the Contract Documents and any and all other
documents relating to a Contract or the related Obligor or Financed Vehicle. As
of the effective date of such Appointment of Custodian, the Contract Documents
and any and all other documents relating to a Contract or the related Obligor or
Financed Vehicle will be delivered to the Successor Custodian in its capacity as
agent of and bailee for the Indenture Trustee (or, if applicable, the Trust).

         For so long as the Servicer is the Custodian of the Contract Documents,
the Servicer need not maintain the Contract Documents held by it in a file area
physically separate from the other installment sales contracts or loans owned or
serviced by it or any of its Affiliates, unless the Insurer requires such
segregation.

use and benefit of all present and future Securityholders, and maintain such
accurate and complete accounts, records and computer systems pertaining to each
Contract File as shall enable the Issuer to comply with this Agreement. In
performing its duties as servicer, the Servicer shall act with reasonable care,
using that degree of skill and attention that the Servicer exercises with
respect to the files relating to all comparable automobile contracts that the
Servicer owns or services for itself or others. The Servicer shall (i) conduct,
or cause to be conducted, periodic physical inspections of the Contract Files
(and the Contract Documents, if the Servicer is acting as Custodian) held by it
under this Agreement and of the related accounts, records and computer systems;
(ii) maintain the Contract Files (and the Contract Documents, if the Servicer is
acting as Custodian) in such a manner as shall enable the Issuer, the Indenture
Trustee and the Insurer to verify the accuracy of the Servicer's record keeping;
(iii) promptly report to the Issuer, the Indenture Trustee and the Insurer any
failure on its part to hold the Contract Files (and the Contract Documents, if
the Servicer is acting as Custodian) and maintain its accounts, records and
computer systems as herein provided and (iv) promptly take appropriate action to
remedy any such failure.

         (b) Maintenance of and Access to Records. The Servicer shall maintain
each Contract File (other than the Contract Documents, unless the Servicer is
acting as Custodian) at the address of the Servicer set forth in Section 9.04,
or at such other location as shall be specified to the Issuer, the Indenture
Trustee and the Insurer by 30 days' prior written notice. The Servicer shall
permit the Issuer, the Indenture Trustee and the Insurer or their respective
duly authorized representatives, attorneys or auditors to inspect the Contract
Files and the related accounts, records and computer systems maintained by the
Servicer at such times as such Persons may request.

         (c) Release of Documents. If the Servicer is acting as Custodian
pursuant to Section 2.04, upon instruction from the Indenture Trustee (a copy of
which shall be furnished to the Issuer and the Insurer), the Servicer shall
release any document in the Contract Files to the Indenture Trustee, the
Indenture Trustee's agent, or the Indenture Trustee's designee, as the case may
be, at such place or places as the Indenture Trustee may designate, as soon as
practicable.

         (d) Monthly Reports. On the Servicer Report Date of each month,
commencing with the month next succeeding the month of the Closing Date, the
Servicer shall deliver to the Issuer, the Indenture Trustee and the Insurer a
certificate of a Servicing Officer stating (i) the Contract Number and
outstanding principal balance of each Contract that has become a Liquidated
Contract since the Business Day immediately preceding the date of the last
certificate delivered pursuant to this subsection (or since the Closing Date in
the case of the first such certificate); (ii) that, if such Contract has been
the subject of a Full Prepayment pursuant to clause (a) of the definition of the
term "Full Prepayment" or is a Liquidated Contract pursuant to clause (iii) of
the definition of the term "Liquidated Contract," all proceeds received in
respect thereof have been deposited in or credited to the Collection Account in
accordance with Section 4.02; (iv) that, if such Contract has been the subject
of a Full Prepayment pursuant to clause (b) of the definition of the term "Full
Prepayment," the correct Purchase Amount has been deposited in or credited to
the Collection Account in accordance with Section 2.03, 3.07 or 4.02; (v) that,
if such Contract is a Liquidated Contract pursuant to clause (ii) of the
definition of the term "Liquidated Contract," there have been deposited in or
credited to the Collection Account the related Net Liquidation Proceeds in
accordance with



                                      -40-
<PAGE>   45

Section 4.02; and (vi) that the Indenture Trustee is authorized to release such
Contract and the related Contract Documents as provided herein.

         (e) Schedule of Title Documents. The Servicer shall deliver to the
Indenture Trustee, the Issuer and the Insurer (i) within 60 days of the Closing
Date with respect to the Funded Contracts and within 60 days of the Prefunding
Closing Date with respect to the Prefunded Contracts, a schedule of Title
Documents for Financed Vehicles which, as of the Closing Date or the Prefunding
Closing Date, as applicable, did not show Onyx or a subsidiary of Onyx as first
lienholder and (ii) within 180 days of the Closing Date with respect to the
Funded Contracts and within 180 days of the Prefunding Closing Date with respect
to the Prefunded Contracts, a schedule of Title Documents for Financed Vehicles
which, as of the date prior to such delivery, do not show Onyx or a subsidiary
of Onyx as first lienholder and as to which the Seller is obligated to
repurchase pursuant to the provisions hereof.

         (f) Electronic Marking of Contracts; Possession. The Servicer shall
cause the electronic record of the Contracts maintained by it to be clearly
marked to indicate that the Contracts have been sold to the Issuer and shall not
in any way assert or claim an ownership interest in the Contracts. It is
intended that pursuant to the applicable provisions of Sections 2.04 and 2.05
hereof and the Appointment of Custodian, the Custodian on behalf of the
Indenture Trustee and the Insurer shall be deemed to have possession of the
Contract Documents for purposes of Section 9-305 of the UCC of the state in
which the Contract Documents are located.

         SECTION 2.06. INSTRUCTIONS; AUTHORITY TO ACT.

         The Servicer shall be deemed to have received proper instructions (a
copy of which shall be furnished to the Issuer and the Insurer) with respect to
the Contract Files upon its receipt of written instructions signed by a
Responsible Officer of the Indenture Trustee.

         SECTION 2.07. INDEMNIFICATION.

         Subject to Section 7.02, the Servicer shall indemnify the Issuer, the
Owner Trustee, the Trust Agent, the Indenture Trustee, the Insurer, the
Custodian and the Securityholders for any and all liabilities, obligations,
losses, compensatory damages, payments, costs or expenses of any kind whatsoever
(including the reasonable fees and expenses of counsel) that may be imposed on,
incurred by or asserted against the Issuer, the Owner Trustee, the Trust Agent,
the Indenture Trustee, the Insurer, the Custodian or the Securityholders as the
result of any improper act or omission in any way relating to the maintenance
and custody by the Servicer of the Contract Files, or the failure of the
Servicer to perform its duties and service the Contracts in compliance with the
terms of this Agreement; provided, however, that the Servicer shall not be
liable to the Owner Trustee, the Trust Agent, the Indenture Trustee, the
Custodian or the Insurer for any portion of any such amount resulting from the
willful misfeasance, bad faith or negligence of the Owner Trustee, the Trust
Agent, the Indenture Trustee, the Custodian or the Insurer, respectively. The
Servicer shall also indemnify and hold harmless the Issuer, the Trust Property,
the Securityholders, the Custodian and the Insurer against any taxes that may be
asserted at any time against any of them with respect to the Contracts,
including any sales, gross receipts, general corporation, personal property,
privilege or license taxes (but exclusive of federal or other income taxes
arising out of payments on the Contracts) and the costs and expenses in
defending against such taxes. The Servicer shall (i) immediately notify the
Issuer and the Indenture Trustee if a claim is made by a third party with



                                      -41-
<PAGE>   46

respect to the Contracts, (ii) assume, with the consent of the Issuer, the
Indenture Trustee and the Insurer, the defense of any such claim, (iii) pay all
expenses in connection therewith, including counsel fees, and (iv) promptly pay,
discharge and satisfy any judgment or decree which may be entered against the
Servicer, the Issuer, the Owner Trustee, the Trust Agent, the Indenture Trustee,
the Insurer, the Custodian or the Securityholders with respect to such
Contracts.

         SECTION 2.08. EFFECTIVE PERIOD AND TERMINATION.

         The appointment of Onyx as custodian shall become effective as of the
Closing Date and shall continue in full force and effect until the earlier of
(i) the execution of the Appointment of Custodian or (ii) the Certificate Final
Scheduled Distribution Date. If Onyx shall subsequently resign as Servicer in
accordance with the terms of this Agreement or if all of the rights and
obligations of the Servicer shall have been terminated pursuant to Section 7.01,
the appointment of the Servicer as Custodian may be terminated by the Insurer,
or if an Insurer Default has occurred and is continuing, (i) if the Notes have
not been paid in full, by the Holders of Notes evidencing not less than 25% of
the outstanding principal amount of the Notes, acting together as a single
class, or by the Indenture Trustee or (ii) if the Notes have been paid in full,
by the Holders of Certificates evidencing not less than 25% of the outstanding
principal amount of the Certificates. As soon as practicable after any
termination of such appointment, Onyx as Custodian and Onyx as Servicer shall,
at the Servicer's expense, deliver or cause the delivery of all Contract
Documents and all Contract Files (including those held in microfiche or
electronic form) to the Indenture Trustee or its agent (or, if the Indenture has
been satisfied and discharged, as directed by the Trust, with the consent of the
Insurer) at such place or places as the applicable party may reasonably
designate and shall cooperate in good faith to effect such delivery. The
foregoing notwithstanding, if the Servicer is acting as Custodian, the Servicer
shall, at the request of the Insurer, deliver the Contract Documents to the
Indenture Trustee in the event that such delivery is required by any Rating
Agency to consider the Securities investment grade without consideration of the
Policy.

         SECTION 2.09. NONPETITION COVENANT.

         (a) Neither the Seller nor the Servicer shall petition or otherwise
invoke the process of any court or government authority for the purpose of
commencing or sustaining a case against the Issuer under any federal or state
bankruptcy, insolvency or similar law or appointing a receiver, liquidator,
assignee, trustee, custodian, sequestrator or other similar official of the
Issuer or any substantial part of its property, or ordering the winding up or
liquidation of the affairs of the Issuer.

         (b) The Servicer shall not, nor cause the Seller to, petition or
otherwise invoke the process of any court or government authority for the
purpose of commencing or sustaining a case against the Seller under any federal
or state bankruptcy, insolvency or similar law or appointing a receiver,
liquidator, assignee, trustee, custodian, sequestrator or other similar official
of the Seller or any substantial part of its property, or ordering the winding
up or liquidation of the affairs of the Seller.

         SECTION 2.10. COLLECTING TITLE DOCUMENTS NOT DELIVERED AT THE CLOSING
DATE.

         In the case of any Funded Contract or Prefunded Contract in respect of
which, in place of a Title Document, the Custodian received on the Closing Date
or the Prefunding Closing Date, as applicable, written evidence from the Dealer
selling the related Financed Vehicle that, or otherwise in respect of which, the
Title Document for such Financed Vehicle showing Onyx or a subsidiary of Onyx as
first lienholder has been applied for from the Registrar of Titles, the Servicer
shall use its best efforts to collect (or in the case of California, to obtain
evidence in the electronic title records of) such Title Document from the
Registrar of Titles as promptly as possible. If such Title Document showing Onyx
or a subsidiary of Onyx as first lienholder is not received by the Servicer (or
in the case of the State of California, verified by the Servicer in the
electronic title records) within 180 days after the Closing Date with respect to
the Funded Contracts or within 180 days after the Prefunding Closing Date with
respect to the Prefunded Contracts, then the representation and warranty in
Section 2.02(b)(iii) as to any such Funded Contracts or the representation and
warranty in Section 2.02(d)(iii) as to any such Prefunded Contracts in respect
of such Contract shall be deemed to have been incorrect in a manner that
materially and adversely affects the Certificateholders, and the Seller shall be
obligated to repurchase such Contract in accordance with Section 2.03.

                                   ARTICLE III

                    ADMINISTRATION AND SERVICING OF CONTRACTS

         SECTION 3.01. DUTIES OF SERVICER.

         The Servicer shall manage, service, administer, and make collections on
the Contracts. The Servicer agrees that its servicing of the Contracts shall be
carried out in accordance with reasonable care and, to the extent more exacting,
the procedures used by the Servicer in respect of such contracts serviced by it
for its own account; provided, however, that, subject to Section 3.02 as to
extensions, the Servicer shall not release or waive the right to collect the
unpaid balance of any Contract. The Servicer's duties shall include collection
and posting of all payments, responding to inquiries of Obligors on the
Contracts, investigating delinquencies, sending payment coupons to Obligors,
reporting tax information to Obligors, accounting for collections, furnishing
monthly and annual statements to the Indenture Trustee, the Issuer and the
Insurer with respect to distributions and the preparation of U.S. Partnership
Tax Returns (Form 1065) for the Owner Trustee to sign and file on an annual
basis, based on a tax year for the Issuer that is the calendar year and any
other tax forms required by any federal, state or local tax authority including
with respect to original issue discount, if any. The Servicer shall have,
subject to the terms hereof, full power and authority, acting alone, and subject
only to the specific requirements and prohibitions of this Agreement, to do any
and all things in connection with such managing, servicing, administration, and
collection that it may deem necessary or desirable; provided, however, that the
Servicer shall commence repossession efforts in respect of any Financed Vehicle
when any payment on the related Contract of which is four or more months
delinquent. Without limiting the generality of the foregoing, but subject to the
provisions of this Agreement, the Servicer is authorized and empowered by the
Indenture Trustee and the Issuer to execute and deliver, on behalf of itself,
the Issuer, the Insurer, the Noteholders, the Certificateholders, the Indenture
Trustee or any of them, any and all instruments of satisfaction or cancellation,
or partial or full release or discharge, and all other comparable instruments,
with respect to the Contracts or to the Financed Vehicles. The Issuer shall
furnish the



                                      -43-
<PAGE>   48

Servicer any documents necessary or appropriate to enable the Servicer to carry
out its servicing and administrative duties hereunder. The Servicer may engage
agents and subservicers to fulfill its duties hereunder; provided, however, that
the Servicer shall remain at all times personally liable for the acts (and
failures to act) of such agents and subservicers.

         On or prior to the Closing Date, the Servicer shall deliver to the
Owner Trustee, the Trust Agent, the Indenture Trustee and the Insurer a list of
Servicing Officers of the Servicer involved in, or responsible for, the
administration and servicing of the Contracts, which list shall from time to
time be updated by the Servicer on request of the Owner Trustee, the Trust
Agent, the Indenture Trustee or the Insurer.

         On the Closing Date, the Servicer shall deposit in the Collection
Account (i) all installments of Monthly P&I due on or after the Initial Cut-Off
Date and received by the Servicer at least two Business Days prior to the
Closing Date; (ii) the proceeds of each Full Prepayment of any Contract and all
partial prepayments on Simple Interest Contracts received by the Servicer on or
after the Initial Cut-Off Date and at least two Business Days prior to the
Closing Date; and (iii) all Net Liquidation Proceeds and Net Insurance Proceeds
received with respect to a Financed Vehicle to which an Initial Contract relates
received on or after the Initial Cut-Off Date and at least two Business Days
prior to the Closing Date.

         On each Prefunding Transfer Date, the Servicer shall deposit in the
Collection Account (i) all installments of Monthly P&I due on or after the
related Prefunding Cut-Off Date and received by the Servicer at least two
Business Days prior to such Prefunding Transfer Date; (ii) the proceeds of each
Full Prepayment of any Prefunded Contract and all partial prepayments on Simple
Interest Contracts received by the Servicer on or after the related Prefunding
Cut-Off Date and at least two Business Days prior to such Prefunding Transfer
Date; and (iii) all Net Liquidation Proceeds and Net Insurance Proceeds received
with respect to a Financed Vehicle to which a Prefunded Contract being
transferred on such date relates, received on or after the related Prefunding
Cut-Off Date and at least two Business Days prior to such Prefunding Transfer
Date.

         Subject to Section 4.02(a) respecting deposits in the Payahead Account,
the Servicer shall deposit in or credit to the Collection Account within two
Business Days of receipt all collections of Monthly P&I due on or after the
related Cut-Off Date received by it on the Contracts together with the proceeds
of all Full Prepayments on all Contracts and all partial prepayments on Simple
Interest Contracts, and any accompanying interest. The Servicer shall likewise
deposit in the Collection Account within two Business Days of receipt all Net
Liquidation Proceeds and Net Insurance Proceeds. As of the last day of each
Collection Period, all amounts received in each Collection Period shall be
applied by the Servicer with respect to each Contract, first, to the Servicer as
additional servicing compensation any amounts due for late fees, extension fees
or similar charges, second to the payment of Monthly P&I, and third, in the case
of partial prepayments on Precomputed Contracts, to the Payahead Account. The
foregoing requirements for deposit in the Collection Account are exclusive, it
being understood that collections in the nature of late payment charges or
extension fees may, but need not be deposited in the Collection Account and may
be retained by the Servicer as additional servicing compensation.

         With respect to payments of Monthly P&I made by Obligors to the
Servicer's lock box, the Servicer shall direct the Person maintaining the lock
box to deposit the amount collected on the Contracts within one Business Day to
the Clearing Account. Such amounts shall be withdrawn from



                                      -44-
<PAGE>   49

the Clearing Account and deposited in the Collection Account no later than the
next following Business Day.

         In order to facilitate the servicing of the Contracts by the Servicer,
the Servicer shall retain, subject to and only to the extent permitted by the
provisions of this Agreement, all collections on the Contracts prior to the time
they are remitted or credited, in accordance with such provisions, to the
Collection Account or the Payahead Account, as the case may be. The Servicer
acknowledges that the unremitted collections on the Contracts are part of the
Trust Property and the Servicer agrees to act as custodian and bailee of the
Indenture Trustee, the Issuer and the Insurer in holding such monies and
collections. The Servicer agrees, for the benefit of the Indenture Trustee, the
Issuer, the Securityholders and the Insurer, to act as such custodian and
bailee, and to hold and deal with such monies and such collections, as custodian
and bailee for the Indenture Trustee, the Issuer and the Insurer, in accordance
with the provisions of this Agreement.

         The Servicer shall retain all data (including, without limitation,
computerized title records) relating directly to or maintained in connection
with the servicing of the Contracts at the address of the Servicer set forth in
Section 9.04 or, upon 15 days' notice to the Issuer, the Indenture Trustee and
the Insurer, at such other place where the servicing offices of the Servicer are
located, and shall give the Issuer, the Indenture Trustee and the Insurer access
to all data (including, without limitation, computerized title records) at all
reasonable times, and, while a Servicer Default shall be continuing, the
Servicer shall, on demand of the Issuer, the Indenture Trustee or the Insurer
deliver or cause to be delivered to the Issuer, the Indenture Trustee or the
Insurer, as the case may be, all data (including, without limitation,
computerized title records and, to the extent transferable, related operating
software) necessary for the servicing of the Contracts and all monies collected
by it and required to be deposited in or credited to the Collection Account or
the Payahead Account, as the case may be.

         All deposits made by the Servicer in any Trust Account shall be made in
immediately available funds.

         The Servicer shall be responsible for the payment of the fees of the
Indenture Trustee, the Owner Trustee and the Trust Agent; provided that any such
fees not paid as of a Distribution Date shall be paid as provided in Section
4.03(a)(ii).

         SECTION 3.02. COLLECTION OF CONTRACT PAYMENTS.

         The Servicer shall use its best efforts to collect all payments called
for under the terms and provisions of the Contracts as and when the same shall
become due and shall use its best efforts to cause each Obligor to make all
payments in respect of his or her Contract to the Servicer. Consistent with the
foregoing, the Servicer may in its discretion (i) waive any late payment charges
in connection with delinquent payments on a Contract or prepayment charges and
(ii) in order to work out a default or an impending default due to the financial
condition of an Obligor, grant up to three extensions of the Due Date of any
payment for periods of 30 days or less, such that the Maturity Date of no
Contract shall, under any circumstances, extend more than 120 days past the
originally scheduled date of the last payment on such Contract and in no event
beyond the Certificate Final Scheduled Distribution Date. The Servicer shall not
extend the Maturity Date of a Contract except as provided in clause (ii) of the
preceding sentence. Except as explicitly permitted by this paragraph,



                                      -45-
<PAGE>   50

the Servicer shall not change any material term of a Contract, including but not
limited to the interest rate, the payment amounts or due dates, or the property
securing such Contract.

         SECTION 3.03. REALIZATION UPON CONTRACTS.

         The Servicer shall use its best efforts, consistent with the servicing
standard specified in Section 3.01, to repossess or otherwise convert the
ownership of the Financed Vehicle securing any Contract as to which no
satisfactory arrangements can be made for collection of delinquent payments.
Such servicing procedures may include reasonable efforts to realize upon any
recourse to Dealers and selling the Financed Vehicle at public or private sale.
In connection with such repossession or other conversion, the Servicer shall
follow such practices and procedures as it shall deem necessary or advisable and
as shall be normal and usual for prudent holders of retail installment sales
contracts and as shall be in compliance with all applicable laws, and, in
connection with the repossession of any Financed Vehicle or any contract in
default, may commence and prosecute any proceedings in respect of such Contract
in its own name or, if the Servicer deems it necessary, in the name of the
Issuer or the Indenture Trustee or on behalf of the Issuer or the Indenture
Trustee. The Servicer's obligations under this Section are subject to the
provision that, in the case of damage to a Financed Vehicle from an uninsured
cause, the Servicer shall not be required to expend its own funds in repairing
such motor vehicle unless it shall determine (i) that such restoration will
increase the proceeds of liquidation of the related Contract, after
reimbursement to itself for such expenses and (ii) that such expenses will be
recoverable by it either as Liquidation Expenses or as expenses recoverable
under an applicable insurance policy or under an insurance reserve established
by the Servicer. The Servicer shall be responsible for all other costs and
expenses incurred by it in connection with any action taken in respect of a
Defaulted Contract; provided, however, that it shall be entitled to
reimbursement of such costs and expenses to the extent they constitute
Liquidation Expenses or expenses recoverable under an applicable insurance
policy. All Net Liquidation Proceeds and Net Insurance Proceeds shall be
deposited directly in or credited to the Collection Account (without deposit in
any intervening account) to the extent required by Section 4.02.

         SECTION 3.04. INSURANCE.

         The Servicer shall cause to be maintained the Blanket Insurance Policy,
and the Servicer shall cause the Indenture Trustee to be the named payee
thereunder with respect to the Contracts; provided, however, that this
obligation may be eliminated or modified in any manner (and this Agreement shall
be amended in accordance with any such elimination or modification as the
parties to the Insurance Agreement and the Rating Agencies may agree) with the
consent of the Insurer but without any requirement to obtain the consent of any
Noteholders or Certificateholders.

         SECTION 3.05. MAINTENANCE OF SECURITY INTERESTS IN FINANCED VEHICLES.

         The Servicer shall take such steps as are necessary to maintain
continuous perfection and priority of the security interest created by each
Contract in the related Financed Vehicle, including but not limited to,
obtaining the execution by the related Obligor and the recording, registering,
filing, re-recording, re-registering, and refiling of all security agreements,
financing statements, continuation statements or other instruments as are
necessary to maintain the security interest granted by such Obligor under each
respective Contract. The Issuer and the Indenture Trustee each hereby authorize
the Servicer to take such steps as are necessary to re-perfect such security
interest on behalf



                                      -46-
<PAGE>   51

of the Issuer in the event of the relocation of a Financed Vehicle or for any
other reason. In the event that the assignment of a Contract to the Issuer and
the subsequent pledge thereof by the Issuer to the Indenture Trustee is
insufficient, without a notation on the related Financed Vehicle's certificate
of title (or, if applicable, in the case of the State of California, the
electronic title record), or without fulfilling any additional administrative
requirements under the laws of the state in which the Financed Vehicle is
located, to grant to the Issuer a perfected security interest in the related
Financed Vehicle and to pledge such perfected security interest to the Indenture
Trustee, Onyx hereby agrees that the identification of Onyx or a subsidiary of
Onyx as the secured party on the certificate of title (or, if applicable, in the
case of the State of California, the electronic title record) is deemed to be in
its capacity as agent of the Indenture Trustee and further agrees to hold such
certificate of title (or, if applicable, in the case of the State of California,
the electronic title record) as the Indenture Trustee's agent and custodian;
provided that, except as provided in Section 7.01 and the Insurance Agreement,
neither the Servicer nor Onyx shall make, nor shall the Issuer or
Securityholders have the right to require that the Servicer or Onyx make, any
such notation on the related Financed Vehicles' certificate of title (or, if
applicable, in the case of the State of California, the electronic title record)
or fulfill any such additional administrative requirement of the laws of the
state in which a Financed Vehicle is located.

         SECTION 3.06. COVENANTS, REPRESENTATIONS AND WARRANTIES OF SERVICER.

         The Servicer hereby makes the following covenants, representations and
warranties on which (i) the Issuer is deemed to have relied in acquiring the
Contracts and (ii) the Insurer is deemed to have relied in issuing the Policy.
Such covenants, representations and warranties speak as of the execution and
delivery of this Agreement and as of the Closing Date or the related Prefunding
Transfer Date, as applicable, but shall survive the sale, transfer and
assignment of the Contracts to the Issuer and the pledge thereof to the
Indenture Trustee pursuant to the Indenture.

         (a) The Servicer covenants as to the Contracts:

                           (i)      The Financed Vehicle securing each Contract
                                    shall not be released from the lien granted
                                    by the Contract in whole or in part, except
                                    as contemplated herein.

                           (ii)     The Servicer shall not impair the rights of
                                    the Securityholders or the Insurer in the
                                    Contracts.

                           (iii)    The Servicer shall not increase the number
                                    of payments under a Contract, nor increase
                                    the amount financed under a Contract, nor
                                    extend or forgive payments on a Contract,
                                    except as provided in Section 3.02.

                           (iv)     The Servicer may consent to the sale or
                                    transfer by an Obligor of any Financed
                                    Vehicle if the original Obligor under the
                                    related Contract remains liable under such
                                    Contract and the transferee assumes all of
                                    the Obligor's obligations thereunder and
                                    upon doing so the credit profile with
                                    respect to such Obligor will not be changed
                                    from adequate to speculative by virtue of
                                    the addition of the transferee's obligation
                                    thereunder.

         (b) The Servicer represents and warrants as of the Closing Date:

                           (vi)     an account denominated "Prefunding Account -
                                    OT 1999-D, The Chase Manhattan Bank,

                                    ACCOUNT"); and

                           (vii)    an account denominated "Capitalized Interest
                                    Account - OT 1999-D, The Chase Manhattan

         In addition, the Indenture Trustee shall establish a trust account to
be maintained in the Corporate Trust Office of the Indenture Trustee denominated
"Payment Account - OT 1999-D, The Chase Manhattan Bank, Indenture Trustee" (the
"PAYMENT ACCOUNT" and, together with the accounts described in clauses (i)
through (vii) above, the "TRUST ACCOUNTS"). The Trust Accounts shall be Eligible
Accounts (subject to the requirement that the Payment Account must be maintained
as provided in the immediately preceding sentence) and relate solely to the
Securities and to the Contracts and, if applicable, the related Eligible
Investments. The location and account numbers of the Trust Accounts as of the
Closing Date are set forth on Schedule II. The Servicer shall give the Issuer,
the Owner Trustee, the Trust Agent, the Indenture Trustee and the Insurer at
least five Business Days' written notice of any change in the location of any
Trust Account and any related account identification information. All amounts,
financial assets and investment property held in, deposited in or credited to,
from time to time, the Trust Accounts (other than the Payahead Account and
investment income credited to the Collection Account and the Capitalized
Interest Account) shall be part of the Trust Property and all amounts, financial
assets and investment property held in, deposited in or credited to, from time
to time, the Collection Account, the Spread Account, the Prefunding Account and
the Capitalized Interest Account shall be invested by the Indenture Trustee in
Eligible Investments pursuant to Section 4.01(c).

         (b) If as of the last day of a Collection Period a payment in an amount
less than the scheduled payment of Monthly P&I has been made for a Precomputed
Contract with respect to which amounts have been deposited in or credited to the
Payahead Account in a preceding Collection Period in accordance with Sections
3.01 and 4.02(a), the Servicer shall withdraw from the Payahead Account and
deposit into the Collection Account by the fifth Business Day preceding the
Distribution Date immediately succeeding such Collection Period the amount equal
to the difference between such scheduled payment of Monthly P&I and such actual
payment, to the extent available from amounts deposited in or credited to the
Payahead Account with respect to such Contract. Amounts on deposit in the
Payahead Account shall be invested by the depository institution maintaining the
Payahead Account upon the written direction of the Servicer in Eligible
Investments which mature not later than the fifth Business Day prior to the
Distribution Date to which such amounts relate, and any earnings on such
Eligible Investments shall be payable to the Servicer monthly. The Payahead
Account and all amounts on deposit therein or credited thereto shall not be
considered part of the Trust Property.

         (c) All funds in the Collection Account, the Spread Account, the
Prefunding Account and the Capitalized Interest Account shall be invested by the
Indenture Trustee (if the Indenture Trustee maintains the applicable account),
or on behalf of the Indenture Trustee by the depository institution maintaining
such account, in Eligible Investments only upon the written direction from the
Servicer or the Insurer, as described below. Subject to the limitations set
forth herein, the Servicer may direct the depository institution maintaining the
Collection Account, the Spread Account, the Prefunding Account and the
Capitalized Interest Account in writing (with a copy of such direction to the



                                      -56-
<PAGE>   61

Indenture Trustee, if the Indenture Trustee is not the applicable depository
institution) to invest funds in the Collection Account, the Spread Account, the
Prefunding Account and the Capitalized Interest Account in Eligible Investments;
provided that (i) in the absence of such directions from the Servicer, the
Insurer may so direct, and (ii) at any time during the continuance of a Servicer
Default, only the Insurer, or for so long as an Insurer Default shall have
occurred and be continuing, only the Issuer, may give such investment
directions. All such investments shall be in the name of the Indenture Trustee
for the benefit of the Noteholders and the Certificateholders, as applicable.
All income or other gain from investment of monies deposited in or credited to
the Collection Account shall be paid by the depository institution maintaining
the Collection Account to the Servicer monthly. All income or other gain from
investment of monies deposited in or credited to the Spread Account, the
Prefunding Account and the Capitalized Interest Account shall be deposited in or
credited to such Account immediately upon receipt, and any loss resulting from
such investment shall be charged to such Account. The maximum permissible
maturities of any investments of funds in the Collection Account, the Spread
Account and the Capitalized Interest Account on any date shall not be later than
the Servicer Report Date immediately preceding the Distribution Date next
succeeding the date of such investment; provided, however, that if the Indenture
Trustee is maintaining the applicable account, such funds may be invested by the
Indenture Trustee in Eligible Investments of the entity that is serving as
Indenture Trustee (or an entity which meets the criteria in clauses (i)(b) or
(i)(c) of the definition of Eligible Account) that mature on the Business Day
prior to such Distribution Date. The maximum permissible maturity of any
investments of funds in the Prefunding Account on any date shall not be later
than the next Business Day. No investment in Eligible Investments may be sold
prior to its maturity. The funds on deposit in the Payment Account, the Note
Distribution and the Certificate Distribution Account shall remain uninvested.

         (d) In the absence of written direction as provided above, all funds
held in the Spread Account, the Collection Account, the Prefunding Account and
the Capitalized Interest Account shall remain uninvested. In addition, if the
applicable depository institution receives what it perceives to be conflicting
directions regarding the investment of funds in the Collection Account, the
Spread Account, the Prefunding Account or the Capitalized Interest Account, the
directions of the Insurer shall control unless an Insurer Default shall have
occurred and be continuing, in which case the directions of the Servicer shall
control unless a Servicer Default shall have occurred and be continuing, in
which case the directions of the Issuer shall control. In addition, the
Indenture Trustee shall not in any way be held liable by reason of any
insufficiency in any of the foregoing Trust Accounts held by or on behalf of the
Indenture Trustee resulting from any investment loss on any Eligible
Investments.

         SECTION 4.02. COLLECTIONS; TRANSFERS TO PAYAHEAD ACCOUNT; REALIZATION
                       UPON POLICY; NET DEPOSITS; TRANSFERS TO PAYMENT ACCOUNT.

         (a) Subject to the last sentence of this Section 4.02(a), the Servicer
shall remit or credit all payments on a daily basis, within two Business Days of
receipt, by or on behalf of Obligors on the Contracts, and all Net Liquidation
Proceeds and Net Insurance Proceeds and other monies as required to the
Collection Account. Prior to the Servicer Report Date, amounts with respect to
Precomputed Contracts which are otherwise required to be deposited in or
credited to the Collection Account pursuant to the immediately preceding
sentence shall instead be deposited in or credited to the Payahead Account to
the extent that such amounts are installments of Monthly P&I which are due in a
Collection Period relating to a Distribution Date subsequent to the Distribution
Date immediately succeeding the date of receipt. The Servicer or the Seller, as
the case may be, each shall



                                      -57-

remit or credit to the Collection Account each Purchase Amount to be remitted by
it with respect to Purchased Contracts on the Business Day preceding the

                                    been reduced to zero, second, to the Holders
                                    of the Class A-2 Notes until the principal
                                    amount of the Class A-2 Notes has been

                           (ix)     to the Certificate Distribution Account, if
                                    such Distribution Date is not the
                                    Certificate Final Scheduled Distribution
                                    Date, after giving effect to the

                                    to the extent of the Certificate Balance, to
                                    be distributed to the Holders of the
                                    Certificates;

                           (x)      to the Insurer, after giving effect to the
                                    distributions described in clauses (i)
                                    through (ix) above, any amounts, including
                                    the Premium, owing to the Insurer under the
                                    Insurance Agreement;

                           (xi)     to the Spread Account, after giving effect
                                    to the distributions described in clauses
                                    (i) through (x) above, the amount, if any,
                                    required to increase the amount therein to
                                    the Spread Account Maximum for such
                                    Distribution Date; and

                           (xii)    any amounts remaining after distribution of
                                    the Accelerated Principal Distributable
                                    Amount as part of the Note Principal
                                    Distributable Amount, if applicable, shall
                                    be deposited into the Spread Account.

Any amounts deposited in the Payment Account pursuant to 4.04(b) with respect to
a Distribution Date and any amounts received by the Indenture Trustee as a
result of a claim under the Policy that represent the Deficiency Amount with
respect to such Distribution Date shall be applied by the Indenture Trustee
solely to make the deposits and distributions referred to in clauses (i) through
(v) and (viii) above, in that order of priority, but only to the extent that the
Net Collections (plus amounts transferred to the Payment Account from the
Prefunding Account, representing earnings from investments therein, and amounts
transferred to the Payment Account from the Capitalized Interest Account, if
any) with respect to such Distribution Date, after application as provided
above, were insufficient to make such deposit or distribution. In addition, if
the Insurer pays any amounts to the Indenture Trustee with respect to a
Distribution Date in connection with the Insurer's election to pay, as provided
in the Policy, all or a portion of any shortfalls in the amount of Net
Collections (plus amounts transferred to the Payment Account from the Prefunding
Account, representing earnings from investments therein, and amounts transferred
to the Payment Account from the Capitalized Interest Account, if any) with
respect to such Distribution Date available to distribute the amounts referred
to in clauses (vii) and (ix) above, the Indenture Trustee shall distribute the
amounts so received from the Insurer as provided in such clauses.

         (b) On each Distribution Date, based solely on the Distribution Date
Statement, the Trust Agent shall distribute all amounts on deposit in the
Certificate Distribution Account to Certificateholders in respect of the
Certificates to the extent of amounts due and unpaid on the Certificates for
principal and interest in the following amounts and order of priority:

                           (i)      the Certificate Interest Distributable
                                    Amount; and

                           (ii)     the Certificate Principal Distributable
                                    Amount to the extent of the Certificate
                                    Balance;



                                      -60-
<PAGE>   65

In addition, any amounts deposited in the Certificate Distribution Account on a
Distribution Date for distribution to holders of the Residual Interests as
provided in Section 4.04(b) shall be so distributed on such Distribution Date by
the Trust Agent. All distributions to Certificateholders or holders of the
Residual Interests shall be made pro rata by check mailed to each
Certificateholder of record on the Record Date next preceding the Distribution
Date for such distribution; provided, that if so directed by the Servicer, in
the case of Certificates registered in the name of a Clearing Agency, such
distribution shall be made by wire transfer in immediately available funds.

         (c) Interest accrued on the Certificates but not paid on any
Distribution Date shall be due and payable on the immediately succeeding
Distribution Date, together with, to the extent permitted by applicable law,
interest on such amount at the Certificate Rate, all as provided in the
definition of Certificate Interest Carryover Shortfall.

         SECTION 4.04. SPREAD ACCOUNT.

         (a) The Spread Account will be held for the benefit of the
Securityholders and the Insurer.

         (b) On each Distribution Date, based solely on the Distribution Date
Statement, the Indenture Trustee shall withdraw funds from the Spread Account,
to the extent funds are on deposit therein, equal to the amount by which the sum
of the amounts set forth in Section 4.03(a), clauses (i) though (v) and (viii)
with respect to such Distribution Date exceeds the amount of Net Collections
(plus amounts transferred to the Payment Account from the Prefunding Account,
representing earnings from investments therein, and amounts transferred to the
Payment Account from the Capitalized Interest Account, if any) available with
respect to such Distribution Date. The Indenture Trustee shall deposit any such
funds withdrawn from the Spread Account into the Payment Account to be
distributed pursuant to Section 4.03(a). Funds shall also be withdrawn from the
Spread Account by the Indenture Trustee, as directed by the Insurer to reimburse
the Insurer for draws with respect to any Preference Amount. If the amount of
cash on deposit in the Spread Account on any Distribution Date (after giving
effect to all deposits thereto or withdrawals therefrom on such Distribution
Date other than withdrawals relating to distributions to be made pursuant to
this sentence) exceeds the maximum amount of the cash component of the Spread
Account, as specified in the definition of "Spread Account Maximum" set forth in
the Insurance Agreement, the Indenture Trustee shall, based solely on the
Distribution Date Statement, distribute any excess first, to the Insurer, to the
extent of any amounts owing to the Insurer pursuant to the Insurance Agreement,
and second, to the Certificate Distribution Account for distribution to holders
of the Residual Interests. Upon any such distributions to the Insurer or the
holders of the Residual Interests, the Securityholders will have no further
rights in, or claims to, such amounts.

         (c) Amounts held in the Spread Account shall be invested in the manner
specified in Section 4.01(c), and such investments shall be made in accordance
with written instructions from the Servicer; provided that, if the Indenture
Trustee does not receive any such written instructions prior to any date on
which an investment decision must be made, the funds held in the Spread Account
will remain uninvested. All such investments shall be made in the name of the
Indenture Trustee or its nominee and such investments shall not be sold or
disposed of prior to their maturity.

         (d) Ninety-one (91) days following the termination of the Trust
pursuant to Section 9.01 of the Trust Agreement, any amounts on deposit in the
Spread Account, after payments of amounts



                                      -61-
<PAGE>   66

due to the Securityholders or the Insurer pursuant to the Insurance Agreement,
shall be paid to the holders of the Residual Interests; provided, however, that
if an insolvency event of the type described in Section 7.01(d) or (e) with
respect to any of the Seller, the Servicer, the Indenture Trustee or the
Securityholders (collectively, the "POTENTIAL PREFERENCE PARTIES") shall have
occurred during the period ending ninety-one (91) days after payment in full to
the Securityholders of all amounts payable with respect to the Securities and
the payment in full of the Repayment Amount then the funds on deposit in the
Spread Account shall be retained until the date all applicable statute of
limitation periods with respect to all applicable preference actions and periods
have expired and during which time no preference action or similar proceeding at
law or in equity is commenced, at which time, the Insurer shall direct the
Indenture Trustee in writing to release all amounts in the Spread Account to the
holders of the Residual Interests, pro rata in proportion to percentage portion
of the Residual Interest (the "PERCENTAGE INTEREST") of each such holder of the
Residual Interests. In the event that any preference action referred to above is
commenced during any applicable statute of limitations period, funds deposited
in the Spread Account shall be retained until the date on which there is a final
determination by a court of competent jurisdiction as to whether any payment or
payments made pursuant to this Agreement, the Indenture, the Indemnification
Agreement or the Insurance Agreement is recoverable from any of the Insurer, the
Noteholders or the Certificateholders. If it is so determined that a payment is
so recoverable, funds deposited in the Spread Account shall be applied by the
Indenture Trustee at the written direction of the Insurer first to pay any and
all such claims with respect to such preference actions as the Securityholders
and the Insurer may be required to pay and then to the holders of the Residual
Interests, pro rata in proportion to their Percentage Interests. If it is
determined that any such payment is not recoverable, the Insurer shall direct
the Indenture Trustee in writing to release all amounts on deposit in the Spread
Account to the holders of the Residual Interests, pro rata in proportion to
their Percentage Interests, upon receipt by the Insurer of both a final order
determining that such payments are not recoverable and an opinion of nationally
recognized bankruptcy counsel to the effect that such appeal is final and not
subject to appeal. For purposes of compliance with this Section 4.04(d), the
Indenture Trustee shall be entitled to rely on written instructions from the
Insurer.

         (e) In the event any of the holders of the Residual Interests seek to
have the amounts remaining on deposit in the Spread Account released to holders
of the Residual Interests prior to the expiration of the ninety-one (91) day
period specified in Section 4.04(d) above, then, if (i) amounts payable with
respect to the Notes and the Certificates have been fully paid to the
Noteholders and the Certificateholders, respectively, (ii) the Repayment Amount
and all other amounts owing to the Insurer pursuant to the Insurance Agreement
have been paid in full, (iii) no case or proceeding described in Sections
7.01(d) or (e) has occurred with respect to the Potential Preference Parties,
and (iv) either (A) the long term unsecured debt of the Seller and the Servicer
is rated "BBB-" or better by Standard & Poor's and "Baa3" or better by Moody's,
(B) the Insurer shall have received a favorable opinion or opinions,
satisfactory in form and substance to the Insurer, from counsel to Onyx, the
Seller and the Servicer, to the effect that in the event a case or proceeding
described in Sections 7.01(d) or (e) were to occur with respect to the Potential
Preference Parties, no payment pursuant to this Agreement or the Insurance
Agreement would be recoverable from either the Insurer or the Securityholders,
and such other matters as the Insurer may reasonably request, or (C) the
Insurer, in its sole discretion, elects to have the remaining amounts on deposit
in the Spread Account paid to the holders of the Residual Interests, then, in
any such event, all remaining amounts on deposit in the Spread Account shall be
paid to the holders of the Residual Interests, pro rata in proportion to their
Percentage Interests.

contemplated herein and in the other Basic Documents, including, without
limitation, any sales, gross receipts, general corporation, tangible personal

Issuer, any taxes asserted with respect to, and as of the date of, the sale of
the Contracts to the Issuer or the issuance and original sale of the Securities,
or (ii) any taxes asserted with respect to ownership of the Contracts, or (iii)
any federal or other income taxes arising out of distributions on the

         (c) The Servicer shall indemnify, defend and hold harmless the Issuer,
the Owner Trustee, the Trust Agent, the Indenture Trustee, the Insurer, the
Custodian (if the Custodian is not the Servicer), their respective officers,

all costs, expenses, losses, claims, damages and liabilities to the extent that

imposed upon any such Person through, the negligence (other than errors in
judgment), willful misfeasance or bad faith of the Servicer or the Seller in the
performance of their respective duties under this Agreement.

         (d) The Servicer shall indemnify, defend and hold harmless the Issuer,
the Owner Trustee, the Trust Agent, the Indenture Trustee, the Insurer, the
Custodian (if the Custodian is not the Servicer) and their respective officers,
directors, agents and employees from and against any and all costs, expenses,
losses, claims, damages and liabilities arising out of or incurred in connection
with the acceptance or performance of the trusts and duties herein and, in the
case of the Owner Trustee and the Trust Agent, in the Trust Agreement and, in
the case of the Indenture Trustee, in the Indenture, except to the extent that
such cost, expense, loss, claim, damage or liability (i) shall be due to the
willful misfeasance, bad faith or negligence of the Owner Trustee, the Trust
Agent, the Indenture Trustee, the Insurer or the Custodian, as the case may be;
(ii) relates to any tax other than the taxes with respect to which either the
Servicer shall be required to indemnify the Issuer, the Owner Trustee, the Trust
Agent, the Indenture Trustee, the Insurer or the Custodian; or (iii) shall

arise from the Trust Agent's, the Owner Trustee's or the Indenture Trustee's
breach of any of their respective representations or warranties set forth
herein, in the Trust Agreement or in the Indenture.

         (e) In addition to the indemnification obligations set forth above, and
without duplication, the Servicer shall indemnify the Owner Trustee, the Trust
Agent, each co-trustee and their respective officers, directors, employees,
successors, assigns, agents and servants from and against any and all
liabilities, obligations, losses, damages, taxes, claims, actions and suits, and
any and all reasonable costs, expenses and disbursements (including reasonable
legal fees and expenses) of any kind and nature whatsoever in any way relating
to or arising out of the Trust Agreement, the other Basic Documents, the Trust
Estate (as defined in the Trust Agreement), the administration of the Trust
Estate or the action or inaction of the Owner Trustee, Trust Agent or any
co-trustee under the Trust Agreement, except to the extent that such
liabilities, obligations, losses, damages, taxes, claims, actions, suits, costs,
expenses and disbursements (i) shall be due to the willful misconduct or
negligence of the Owner Trustee, the Trust Agent, a co-trustee or such other
party seeking indemnification, as the case may be, or (ii) shall arise from the
inaccuracy of any representation or warranty contained in Section 7.03 of the
Trust Agreement expressly made by the Owner Trustee or the Trust Agent, as the
case may be. In the event of any claim, action or proceeding for which indemnity
will be sought pursuant to this Section 6.01(e), the choice of legal counsel by
the Owner Trustee or the Trust Agent, as applicable, shall be subject to the
approval of the Servicer, which approval shall not be unreasonably withheld.

         Indemnification under this Section shall include, without limitation,
reasonable fees and expenses of counsel and expenses of litigation. If the
Servicer shall have made any indemnity payments pursuant to this section and the
recipient thereafter collects any of such amounts from others, the recipient
Person shall promptly repay such amounts to the Servicer, without interest.

         This Section 6.01 shall survive the resignation or removal of the Owner
Trustee, the Trust Agent, the Custodian and the Indenture Trustee and the
termination of this Agreement, the Trust Agreement and the Indenture.

         SECTION 6.02. CORPORATE EXISTENCE; STATUS AS SERVICER; MERGER.

         (a) The Servicer shall keep in full effect its existence, rights and
franchises as a corporation incorporated under the laws of the State of

foreign corporation in each jurisdiction in which such qualification is or shall
be necessary to protect the validity and enforceability of the Contract
Documents and this Agreement.

         (b) The Servicer shall not consolidate with or merge into any other
corporation or convey, transfer or lease all or substantially all of its assets
as an entirety to any Person or engage in any corporate transaction pursuant to
which the surviving or successor entity is not Onyx Acceptance Corporation,
unless (i) such entity is at least rated investment grade by the Rating
Agencies, (ii) the Insurer shall have consented thereto in writing and (iii)
such entity executes and delivers to the Issuer, the Indenture Trustee and the
Insurer an agreement in form and substance reasonably satisfactory to the
Issuer, the Indenture Trustee and the Insurer, which contains an assumption by
such successor entity of the due and punctual performance and observance of each
covenant and condition to be performed or observed by the Servicer under this
Agreement.

         SECTION 6.03. PERFORMANCE OF OBLIGATIONS.

         (a) The Servicer shall punctually perform and observe all of its
obligations and agreements contained in this Agreement.

         (b) The Servicer shall not take any action, or permit any action to be
taken by others, which would excuse any person from any of its covenants or
obligations under any of the Contract Documents or under any other instrument
included in the Trust Property, or which would result in the amendment,
hypothecation, subordination, termination or discharge of, or impair the
validity or effectiveness of, any of the Contract Documents or any such
instrument, except as expressly provided herein and therein.

         SECTION 6.04. SERVICER NOT TO RESIGN; ASSIGNMENT.

         (a) The Servicer shall not resign from the duties and obligations
hereby imposed on it except upon determination by its Board of Directors that by
reason of change in applicable legal requirements the continued performance by
the Servicer of its duties hereunder would cause it to be in violation of such
legal requirements in a manner which would result in a material adverse effect
on the Servicer or its financial condition, said determination to be evidenced
by a resolution of its Board of Directors to such effect accompanied by an
Opinion of Counsel, satisfactory to the Issuer, the Insurer and the Indenture
Trustee, to such effect. No such resignation shall become effective unless and
until (i) the Indenture Trustee assumes all of the Servicer's obligations under
this Agreement or (ii) a new servicer acceptable to the Issuer, the Indenture
Trustee and the Insurer is willing to service the Contracts and enters into a
servicing agreement with the Issuer, the Indenture Trustee and the Insurer in
form and substance substantially similar to this Agreement and satisfactory to
the Issuer, the Indenture Trustee and the Insurer, and each Rating Agency
confirms that the selection of such new servicer will not result in the
qualification, reduction or withdrawal of its then-current rating of each Class
of Notes and the Certificates assigned by such Rating Agency. No such
resignation by the Servicer shall affect the obligation of the Servicer to
repurchase Contracts pursuant to Section 3.07.

         (b) Except as specifically permitted in this Agreement, the Servicer
may not assign this Agreement or any of its rights, powers, duties or
obligations hereunder; provided that (i) the Servicer may assign this Agreement
in connection with a consolidation, merger, conveyance, transfer or lease made
in compliance with Section 6.02(b).

         (c) Except as provided in Sections 6.04(a) and (b), the duties and
obligations of the Servicer under this Agreement shall continue until this
Agreement shall have been terminated as provided in Section 8.01 or the Trust
shall have been terminated as provided by the terms of the Trust Agreement, and
shall survive the exercise by the Issuer, the Indenture Trustee or the Insurer
of any right or remedy under this Agreement, or the enforcement by the Issuer,
the Indenture Trustee, any Certificateholder or Noteholder, or the Insurer of
any provision of the Notes, the Certificates, the Insurance Agreement or this
Agreement.

         (d) The resignation of the Servicer in accordance with this Section
shall not affect the rights of the Seller hereunder. If the Servicer resigns
pursuant to this Section, its appointment as custodian may be terminated
pursuant to Section 2.08.

         SECTION 6.05. LIMITATION ON LIABILITY OF SERVICER AND OTHERS.

         Neither the Servicer nor any of the directors, officers, employees or
agents of the Servicer shall be under any liability to the Issuer, the
Noteholders or the Certificateholders, except as provided under this Agreement,
for any action taken or for refraining from the taking of any action pursuant to
this Agreement or for errors in judgment; provided, however, that this provision
shall not protect the Servicer or any such person against any liability that
would otherwise be imposed by reason of willful misfeasance, bad faith or
negligence (except errors in judgment) in the performance of duties or by reason
of reckless disregard of obligations and duties under this Agreement. The
Servicer and any director, officer, employee or agent of the Servicer may rely
in good faith on any document of any kind prima facie properly executed and
submitted by any person respecting any matters arising under this Agreement.

         Except as provided in this Agreement, the Servicer shall not be under
any obligation to appear in, prosecute or defend any legal action that shall not
be incidental to its duties to service the Contracts in accordance with this
Agreement, and that in its opinion may involve it in any expense or liability;
provided, however, that the Servicer may undertake any reasonable action that it
may deem necessary or desirable in respect of this Agreement and the other Basic
Documents and the rights and duties of the parties to this Agreement and the
other Basic Documents and the interests of the Securityholders under this
Agreement and the other Basic Documents.

                                   ARTICLE VII

                                     DEFAULT

         SECTION 7.01. EVENTS OF DEFAULT.

         If any one of the following events (each, a "SERVICER DEFAULT") shall
occur and be continuing:

         (a) any failure by the Servicer to deposit or credit to the Collection
Account or the Payahead Account any amount required under this Agreement to be
so deposited or credited that shall continue unremedied for a period of three
Business Days after written notice of such failure is received by the Servicer
from the Issuer, the Indenture Trustee or the Insurer or after discovery of such
failure by an officer of the Servicer;

         (b) the Insurer, the Indenture Trustee, the Issuer or the Trust Agent
shall not have received a report in accordance with Section 3.09 by the Servicer
Report Date with respect to which such report is due;

         (c) any failure on the part of the Seller or the Servicer duly to
observe or to perform in any material respect any other covenants or agreements
of the Seller or the Servicer set forth in this Agreement or any other Basic
Document, which failure shall (i) materially and adversely affect the rights of
the Securityholders, the Insurer, the Issuer, the Owner Trustee or the Indenture
Trustee and (ii) continue unremedied for a period of 30 days after the date on
which written notice of such failure, requiring the same to be remedied, shall
have been given (A) to the Seller or the Servicer, as the case may be, by the
Insurer, the Issuer, the Owner Trustee or the Indenture Trustee or (B) to the
Seller or the Servicer, as the case may be, and to the Issuer and the Indenture
Trustee by (1) the

Holders of Notes, acting together as a single class, evidencing in the aggregate
not less than 25% of the outstanding amount of the Notes, or (2) if the Notes
have been paid in full, by Certificateholders evidencing not less than 25% of
the outstanding Certificate Balance, or (3) so long as no Insurer Default has
occurred and is continuing, by the Insurer;

         (d) the entry of a decree or order for relief by a court or regulatory
authority having jurisdiction in respect of the Servicer or the Seller in an
involuntary case under the federal bankruptcy laws, as now or hereafter in
effect, or another present or future, federal or state, bankruptcy, insolvency
or similar law, or appointing a receiver, liquidator, assignee, trustee,
custodian, sequestrator or other similar official of the Servicer or the Seller
or of any substantial part of its property, or ordering the winding up or

any such decree or order unstayed and in effect for a period of 60 consecutive
days or the commencement of an involuntary case under the federal bankruptcy
laws, as now or hereinafter in effect, or another present or future federal or
state bankruptcy, insolvency or similar law and such case is not dismissed
within 60 days;

         (e) the commencement by the Servicer or the Seller of a voluntary case
under the federal bankruptcy laws, as now or hereafter in effect, or any other
present or future, federal or state, bankruptcy, insolvency or similar law, or
the consent by the Servicer or the Seller to the appointment of or taking
possession by a receiver, liquidator, assignee, trustee, custodian, sequestrator
or other similar official of the Servicer or the Seller or of any substantial
part of its property or the making by the Servicer or the Seller of an
assignment for the benefit of creditors or the failure by the Servicer or the
Seller generally to pay its debts as such debts become due or the taking of
corporate action by the Servicer or the Seller in furtherance of any of the
foregoing;

         (f) any change of control of the Servicer in violation of the covenant
set forth in Section 6.02 hereof;

         (g) any representation, warranty or statement of the Servicer or the
Seller made in this Agreement or any certificate, report or other writing
delivered pursuant hereto shall prove to be incorrect in any material respect as
of the time when the same shall have been made (excluding, however, any
representation or warranty as to which Section 2.03 or 3.07 shall be applicable
so long as the Servicer or the Seller shall be in compliance with Section 2.03
or 3.07, as the case may be), and the incorrectness of such representation,
warranty or statement has a material adverse effect on the Securityholders or
the Insurer and, within 30 days after written notice thereof shall have been
given to the Servicer or the Seller by the Indenture Trustee or the Issuer or by
the Holders of Notes, acting together as a single class, evidencing in the
aggregate not less than 25% of the outstanding amount of the Notes, or, if the
outstanding amount of the Notes has been reduced to zero, the Certificateholders
evidencing in the aggregate not less than 25% of the outstanding Certificate
Balance or, so long as no Insurer Default has occurred and is continuing, by the
Insurer, the circumstance or condition in respect of which such representation,
warranty or statement was incorrect shall not have been eliminated or otherwise
cured;

         (h) a Trigger Event (as defined in the Insurance Agreement) shall have
occurred;

then and in each and every case, so long as such Servicer Default shall not have
been remedied, either (i) the Insurer, provided no Insurer Default has occurred
and is continuing or (ii) if an Insurer Default has occurred and is continuing
(a) if the Notes have not been paid in full, the holders of



                                      -72-
<PAGE>   77

Notes evidencing not less than 25% of the outstanding principal amount of the
Notes, acting together as a single class or the Indenture Trustee acting on
behalf of the Noteholders, and not the Seller or the Certificateholders or (b)
if the Notes have been paid in full and the Indenture has been discharged in
accordance with its terms, the Holders of Certificates evidencing not less than
25% of the outstanding Certificate Balance, by notice then given in writing to
the Servicer (and to the Insurer, the Indenture Trustee and the Issuer if given
by the Noteholders or the Certificateholders) may terminate all the rights and
obligations of the Servicer under this Agreement. Upon such termination,
termination of the Servicer as custodian, if the Servicer is acting as such, can
be made pursuant to Section 2.08. On or after the receipt by the Servicer of
such written notice, all authority and power of the Servicer under this
Agreement, whether with respect to the Notes, the Certificates, the Contracts or
otherwise, shall, without further action, pass to and be vested in the Indenture
Trustee or such Successor Servicer as may be appointed under Section 7.02; and,
without limitation, the Indenture Trustee and the Issuer are hereby authorized
and empowered to execute and deliver on behalf of the Servicer, as attorney-in
fact or otherwise, any and all documents and other instruments, and to do or
accomplish all other acts or things necessary or appropriate to effect the
purposes of such notice of termination, whether to complete the transfer and
endorsement of the Contracts and related documents, or otherwise. The Servicer
shall cooperate with the Indenture Trustee and the Issuer in effecting the
termination of the responsibilities and rights of the Servicer under this
Agreement, including the transfer to the Indenture Trustee for administration by
it of all cash amounts that (i) shall at the time be held by the Servicer for
deposit in, or shall have been deposited by the Servicer in, the Collection
Account or Payahead Account or (ii) shall thereafter be received by it with
respect to any Contract.

         Notwithstanding the foregoing, in the event that Onyx is not the
Servicer, then all references to the Seller in this Section 7.01 shall be of no
force and effect, and no act of Seller shall constitute a Servicer Default
hereunder.

         SECTION 7.02. TRUSTEE TO ACT; APPOINTMENT OF SUCCESSOR.

         Upon the termination of the Servicer by the Insurer pursuant to Section
7.01 or resignation of the Servicer pursuant to Section 6.04, the Insurer shall
appoint a successor servicer ("SUCCESSOR SERVICER"). Upon the termination of the
Servicer by the Indenture Trustee, the Noteholders or the Certificateholders
pursuant to Section 7.01, or upon the resignation of the Servicer pursuant to
Section 6.04 in the event that the Insurer is not entitled to appoint a
successor servicer by operation of Section 9.08, (i) if the Notes have not been
paid in full, the Indenture Trustee shall be the Successor Servicer, and (ii) if
the Notes have been paid in full, the Owner Trustee, acting at the direction of
the Holders of Certificates evidencing not less than 51% of the outstanding
Certificate Balance, shall appoint a Successor Servicer. The Successor Servicer
shall succeed to all the responsibilities, duties and liabilities of the
Servicer under this Agreement, except that such Successor Servicer shall not be
obligated to purchase Contracts pursuant to Section 3.07. If the Indenture
Trustee acts as Successor Servicer, the Indenture Trustee shall be entitled to
such compensation (whether payable out of the Collection Account or otherwise)
as the Servicer would have been entitled to under this Agreement if no such
notice of termination shall have been given. Notwithstanding the foregoing, if
the Notes have not been paid in full, the Indenture Trustee may, if it shall be
unwilling to act, or shall, if it shall be legally unable to so act, appoint, or
petition a court of competent jurisdiction to appoint, any established financial
institution, having a net worth of not less than $50,000,000 and whose regular
business shall include the servicing of automotive retail installment sales
contracts, as the successor to the Servicer under this Agreement. Pending



                                      -73-
<PAGE>   78

appointment of any such Successor Servicer, the Indenture Trustee shall act in
such capacity as provided above. In connection with such appointment, the
Indenture Trustee or any other Successor Servicer may make such arrangements for
the compensation of such successor out of payments on Contracts as it, the
Insurer and such successor shall agree; provided, however, (i) that such amount
shall equal the product of a fixed percentage rate and the Principal Balance, as
of the commencement of each Collection Period, of each Contract and (ii) that no
such compensation shall be in excess of that previously permitted the Servicer
under this Agreement. The Indenture Trustee and such successor shall take such
action, consistent with this Agreement, as shall be necessary to effectuate any
such succession.

         SECTION 7.03. NOTIFICATION TO NOTEHOLDERS AND CERTIFICATEHOLDERS.

         Upon any termination of, or appointment of a successor to, the Servicer
pursuant to this Article, the Trust Agent shall give prompt written notice
thereof to Certificateholders at their respective addresses appearing in the
Certificate Register, and the Indenture Trustee shall give prompt written notice
thereof to Noteholders at their respective addresses appearing in the Note
Register.

         SECTION 7.04. WAIVER OF PAST DEFAULTS.

         Upon the occurrence of a Servicer Default, unless an Insurer Default
shall have occurred and be continuing, the Insurer, and only the Insurer, may
waive any default by the Servicer or the Seller, as the case may be, in the
performance of its obligations under this Agreement except a Servicer Default in
making any required deposits to or payment from the Trust Accounts in accordance
with this Agreement. Upon the occurrence of a Servicer Default, if an Insurer
Default has occurred and is continuing, (i) the Holders of Notes evidencing not
less than 51% of the outstanding principal amount of the Notes, on behalf of all
Securityholders, or (ii) if all the Notes have been paid in full and the
Indenture has been discharged in accordance with its terms, Holders of
Certificates evidencing not less than 25% of the outstanding Certificate
Balance, on behalf of all of the Certificateholders, shall have the right to
waive any default by the Servicer or the Seller, as the case may be, in the
performance of its obligations under this Agreement except a Servicer Default in
making any required deposits to or payment from the Trust Accounts in accordance
with this Agreement. A Servicer Default in making any required deposits to or
payment from the Trust Accounts in accordance with this Agreement may only be
waived with the consent of the Insurer (if no Insurer Default shall have
occurred and be continuing) and Holders evidencing 100% of the outstanding
principal amount of the Notes or, if the Notes have been paid in full, Holders
of Certificates evidencing 100% of the outstanding Certificate Balance. No such
waiver shall impair the Insurer's or the Securityholders' rights with respect to
subsequent defaults.

         SECTION 7.05. INSURER DIRECTION OF INSOLVENCY PROCEEDINGS.

         The Indenture Trustee, upon the actual knowledge of a Responsible
Officer of the Indenture Trustee, shall promptly notify the Insurer of (i) the
commencement of any of the events or proceedings (individually, an "INSOLVENCY
PROCEEDING") described in the Section 7.01(d) or 7.01(e) hereof and (ii) the
making of any claim in connection with any Insolvency Proceeding seeking the
avoidance as a preferential transfer (a "PREFERENCE CLAIM") of any payment of
principal of, or interest on, any Notes or Certificates. Any Preference Amounts
paid by the Insurer shall be reimbursed to the Insurer as provided in Section
4.03(a) and 4.04(b). Each Noteholder, by its



                                      -74-
<PAGE>   79

purchase of Notes, each Certificateholder, by its purchase of Certificates, the
Owner Trustee, the Trust Agent and the Indenture Trustee hereby agree that, so
long as no Insurer Default has occurred and is continuing, the Insurer may at
any time during the continuation of an Insolvency Proceeding direct all matters
relating to such Insolvency Proceeding, including, without limitation, (i) all
matters relating to any Preference Claim, (ii) the direction of any appeal of
any order relating to any Preference Claim and (iii) the posting of any surety
or performance bond pending any such appeal. The Insurer shall be subrogated to
the rights of the Indenture Trustee, the Owner Trustee, the Trust Agent and each
Securityholder in the conduct of any Insolvency Proceeding, including, without
limitation, all rights of any party to an adversary proceeding action with
respect to any court order issued in connection with any such Insolvency
Proceeding.

                                  ARTICLE VIII

                                   TERMINATION

         SECTION 8.01. OPTIONAL PURCHASE OF ALL CONTRACTS; SATISFACTION AND
                       DISCHARGE OF THE INDENTURE.

         (a) On each Distribution Date as of which the Pool Balance is 10% or
less of the Original Pool Balance, the Servicer shall have the option to
purchase the remaining Contracts from the Trust. Notice of the exercise of such
option shall be given by the Servicer to the Issuer, the Trust Agent, the
Indenture Trustee and the Insurer not later than the 10th day prior to the
specified Distribution Date and not earlier than the 15th day of the month prior
to the month of the specified Distribution Date. To exercise such option, the
Servicer shall pay to the Indenture Trustee for the benefit of the
Securityholders, by deposit in the Collection Account on the Business Day
immediately preceding the related Distribution Date, the greater of (i) the sum
of (x) the Pool Balance on the date of repurchase plus (y) accrued and unpaid
interest on the Contracts and (ii) the sum of (x) the aggregate unpaid principal
amount of the Securities plus (y) accrued and unpaid interest thereon plus (z)
all amounts due to the Insurer under the Insurance Agreement. Such purchase
shall be deemed to have occurred on the last day of the related Collection
Period.

         (b) Notice of any termination of the Trust shall be given by the
Servicer to the Owner Trustee, the Trust Agent, the Insurer and the Indenture
Trustee as soon as practicable after the Servicer has received notice thereof.
Such notice shall conform to the notice described in Section 9.01(c) of the
Trust Agreement.

         (c) Following the satisfaction and discharge of the Indenture and the
payment in full of the principal of and interest on the Notes, the
Certificateholders will succeed to the rights of the Noteholders hereunder and
the Owner Trustee and, on its behalf, the Trust Agent, will succeed to the
rights of, and assume the obligations of, the Indenture Trustee pursuant to this
Agreement; provided, however, that the Indenture Trustee shall continue to make
claims under the Policy as provided herein.

         SECTION 8.02. TRANSFER TO THE INSURER.

         If (i) there are one or more Outstanding Contracts at the end of the
Collection Period ending immediately prior to the Certificate Final Scheduled
Distribution Date and (ii) an amount sufficient to pay the Certificate
Distributable Amount on the Certificate Final Scheduled Distribution Date has
been deposited with the Indenture Trustee by the Insurer for the benefit of the
Certificateholders, then on the Certificate Final Scheduled Distribution Date
the Certificates shall be deemed to be transferred by the Certificateholders to
the Insurer or its designee as purchaser thereof at the opening of business on
the Certificate Final Scheduled Distribution Date and the Owner Trustee, on
behalf of the Trust, shall execute, and the Trust Agent shall authenticate and
deliver to the Insurer or its designee, in the name of the Insurer or its
designee, as the case may be, a new Certificate evidencing the entire
Certificate Balance. Such new Certificate shall have the same terms as the
Certificates deemed transferred by the Certificateholders. No service charge
shall be made for the issuance of such Certificate to the Insurer or its
designee, but the Owner Trustee or Trust Agent may require payment of a sum
sufficient to cover any tax or other governmental charge imposed in connection
therewith. Such transfer shall not diminish or restrict the Insurer's rights
hereunder or under the Insurance Agreement.

                                   ARTICLE IX

                                  MISCELLANEOUS

         SECTION 9.01. AMENDMENT.

         (a) This Agreement may be amended by the Issuer, the Seller, the
Servicer, the Indenture Trustee and the Trust Agent, collectively, with the
prior written consent of the Insurer, but without the consent of any
Securityholders, to cure any ambiguity, to correct or supplement any provisions
in this Agreement which are inconsistent with the provisions herein, or to make
any other provisions with respect to matters or questions arising under this
Agreement which are not inconsistent with the provisions of this Agreement;
provided, however, that any such action shall not materially and adversely
affect the interests of any Securityholder; and provided, further, that any such
amendment shall be deemed not to materially and adversely affect the interests
of any Securityholder if the Person requesting the amendment obtains a letter or
confirmation from each Rating Agency to the effect that such amendment would not
result in a downgrading or withdrawal of the ratings then assigned to the
applicable Securities by such Rating Agency.

         (b) This Agreement may also be amended by the Issuer, the Seller, the
Servicer, the Indenture Trustee and the Trust Agent, with the consent of the
Insurer and (i) for so long as any Notes are outstanding, the Holders of Notes
evidencing in the aggregate not less than 51% of the principal amount of the
Notes then outstanding, acting together as a single class or (ii) if the Notes
have been paid in full, the Holders of Certificates evidencing not less than 51%
of the outstanding Certificate Balance, for the purpose of adding any provisions
to or changing in any manner or eliminating any of the provisions of this
Agreement, or of modifying in any manner the rights of the Noteholders or the
Certificateholders; provided, however, that no such amendment shall (i) increase
or reduce in any manner the amount of, or accelerate or delay the timing of,
collections of payments on the Contracts or distributions that shall be required
to be made for the benefit of the Noteholders or Certificateholders or (ii)
reduce the aforesaid percentage of the outstanding amount of the Notes



                                      -76-
<PAGE>   81

the Holders of which are required to consent to any such amendment, without the
consent of all affected Noteholders and Certificateholders.

         (c) Promptly after the execution of any such amendment or consent, the
Trust Agent and the Indenture Trustee, as the case may be, shall furnish the
written notification of the substance of such amendment or consent to each
Certificateholder and Noteholder, respectively.

         (d) It shall not be necessary for the consent of Noteholders and
Certificateholders pursuant to Section 9.01(b) to approve the particular form of
any proposed amendment or consent, but it shall be sufficient if such consent
shall approve the substance thereof. The manner of obtaining such consents and
of evidencing the authorization by Noteholders and Certificateholders of the
execution thereof shall be subject to such reasonable requirements as the Trust
Agent or the Indenture Trustee may prescribe. Any consent by a Securityholder to
an amendment of the Agreement shall be conclusive and binding on such
Securityholder and upon all future Securityholders of such Security and of any
Security issued upon the transfer thereof or in exchange thereof or in lieu
thereof whether or not notation of such consent is made upon such Security.

         (e) The Trust Agent and the Indenture Trustee may, but shall not be
obligated to, enter into any such amendment which affects the Trust Agent's or
the Indenture Trustee's own rights, duties or immunities under this Agreement or
otherwise and any such amendment shall be unenforceable in its entirety absent
the execution of such amendment by the Trust Agent and the Indenture Trustee.

         SECTION 9.02. PROTECTION OF TITLE TO TRUST.

         (a) The Servicer shall execute and file such financing statements and
cause to be executed and filed such continuation statements, all in such manner
and in such places as may be required by law fully to preserve, maintain and
protect the interest of the Issuer, the Securityholders, the Indenture Trustee,
the Trust Agent and the Insurer in the Contracts and in the proceeds thereof.
The Servicer shall deliver (or cause to be delivered) to the Trust Agent and the
Indenture Trustee file-stamped copies of, or filing receipts for, any document
filed as provided above, as soon as available following such filing.

         (b) Neither the Seller nor the Servicer shall change its name, identity
or corporate structure in any manner that would, could or might make any
financing statement or continuation statement filed in accordance with Section
9.02(a) seriously misleading within the meaning of Section 9-402(7) of the UCC,
unless it shall have given the Insurer, the Trust Agent and the Indenture
Trustee at least 60 days' prior written notice thereof.

         (c) The Seller and the Servicer shall give the Insurer, the Trust Agent
and the Indenture Trustee at least 60 days' prior written notice of any
relocation of the principal executive office of the Seller and the Servicer if,
as a result of such relocation, the applicable provisions of the UCC would
require the filing of any amendment of any previously filed financing or
continuation statement or of any new financing statement. The Servicer shall at
all times maintain each office from which it shall service Contracts, and its
principal executive office, within the United States.

         (d) The Servicer shall maintain or cause to be maintained accounts and
records as to each Contract accurately and in sufficient detail to permit (i)
the reader thereof to know at any time the



                                      -77-
<PAGE>   82

status of such Contract, including payments and recoveries made and payments
owing (and the nature of each) and (ii) reconciliation between payments or
recoveries on (or with respect to) each Contract and the amounts from time to
time deposited in or credited to the Collection Account and the Payahead Account
in respect of such Contract.

         (e) The Servicer shall maintain or cause to be maintained its computer
systems so that, from and after the time of sale under this Agreement of the
Contracts to the Issuer, the Servicer's master computer records (including any
backup archives) that shall refer to a Contract indicate clearly the interest of
the Issuer and the Indenture Trustee in such Contract and that such Contract is
owned by the Issuer and has been pledged to the Indenture Trustee.

         (f) If at any time the Seller or the Servicer shall propose to sell,
grant a security interest in, or otherwise transfer any interest in automotive
retail installment sales contracts or installment loan agreements to any
prospective purchaser, lender or other transferee, the Servicer shall give or
cause to be given to such prospective purchaser, lender or other transferee
computer tapes, records or print-outs (including any restored from back-up
archives) that, if they shall refer in any manner whatsoever to any Contract,

voting rights, which the Noteholders or Certificateholders are entitled to
exercise pursuant to this Agreement, without any consent of such Noteholders or
Certificateholders; provided, however, that without the consent of each
Noteholder, Certificateholder or Residual Interestholder affected thereby, the

material respect the interests of the Holders of any Notes, Certificates or

Contracts and/or the assignment of any or all of the Issuer's rights and
obligations hereunder to the Indenture Trustee.

         SECTION 9.11. LIMITATION OF LIABILITY OF OWNER TRUSTEE.
