         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

         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


                                       4
<PAGE>   5

         correct, and each Contract will satisfy the representations and
         warranties set forth in Section 2.02(b) of the Servicing Agreement.

                  (vi) 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.

                  (vii) 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.

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

                  (ix) 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
the terms and conditions herein set forth, the Company agrees to sell to each
Underwriter, and each Underwriter agrees, severally and not jointly, to purchase
from the Company the aggregate principal amount of each class of Securities set
forth opposite such Underwriter's name on Schedule I hereto and at the price set
forth on such Schedule plus accrued interest, if any, from the Closing Date.


                                       5

         The Company will deliver the Securities to the Underwriters against
payment of the purchase price in immediately available funds by wire transfer to
the order of the Company at the offices of Andrews & Kurth L.L.P., 1717 Main
Street, Suite 3700, Dallas, Texas 75201 at 10:00 a.m., New York City time on
August 31, 1999 or at such other time not later than seven full business days
thereafter as the Underwriters and the Company determine, such time being herein
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
numbers as the Underwriters shall reasonably request not later than 48 hours
prior to the Closing Date. The Company shall make such global notes or
certificates, as applicable, representing the Securities available for
inspection by the Underwriters at the office at which the Securities are to be
delivered no later than 10:00 a.m., New York City time, on the business day
prior to the Closing Date.

         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.

                  (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


                                       6
<PAGE>   7

         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 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


                                       7
<PAGE>   8

         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 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


                                       8
<PAGE>   9

         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 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


                                       9
<PAGE>   10

         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
         amended, any order of the Commission thereunder or pursuant to a
         "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) On or before the Closing Date the Company shall cause its
         computer records relating to the Contracts to be marked to show the
         Trust's absolute ownership of the Contracts and shall cause the
         Servicer to mark its computer records relating to the Contracts to show
         the sale to the Company of the Contracts and the subsequent transfer of
         the 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 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
         within the time period allotted for such filing pursuant to the
         No-Action Letter; provided, however, that prior to such filing of an
         ABS Term Sheet (other than any ABS Term Sheets that are not based on
         the Contract Pool information) by the Company, each of the Underwriters
         must comply with their obligations pursuant to Section 4 and the
         Company must receive a letter from PricewaterhouseCoopers, certified
         public accountants, satisfactory in form and substance to the Company,
         to the effect that such accountants have performed certain specified
         procedures, all of which have been agreed to by the Company, as a
         result of which PricewaterhouseCoopers have determined that the
         information included in such ABS Term Sheet (if any), provided by the
         Underwriters to the Company for filing on a current report on Form 8-K
         pursuant to Section 4 and, if the Company then so specifies, this
         subsection (xii), and that the accountants have examined in accordance
         with such agreed upon procedures, is accurate except as to such matters
         that are not deemed by the Company to be material. The Company shall
         file any corrected ABS Term Sheets described in Section 4(b)(vi) as
         soon as practicable following receipt thereof.

         6. Payment of Expenses. The Company will pay or cause to be paid all

accuracy of the representations and warranties on the part of the Company
herein, to the accuracy of the written statements of officers of the Company
made pursuant to the provisions hereof, to the performance by the Company of its
obligations hereunder and to the following additional conditions precedent:

                  (i) On or prior to the date of this Agreement, the
         Representative shall have received a letter, dated the date of this
         Agreement, of PricewaterhouseCoopers and substantially in the form
         heretofore agreed, which letter shall be in form and substance agreed
         to by the Representative.

                  (ii) The Registration Statement shall have become effective
         prior to the Execution Time, and prior to the Closing Date, no stop
         order suspending the effectiveness of the Registration Statement shall
         have been issued and no proceedings for that purpose shall have been
         instituted or, to the knowledge of the Company or the Representative,
         shall be contemplated by the Commission or by any authority
         administering any state securities or blue sky law; the Prospectus and
         any supplements thereto shall have been filed (if required) with the
         Commission in accordance with the Rules and Regulations and the
         applicable paragraphs of Section 5 hereof; if filing of the Prospectus,
         or any supplement thereto, is required pursuant to Rule 424(b), the
         Prospectus shall be filed in the manner and within the time period
         required by Rule 424(b); and no stop order suspending the effectiveness
         of the Registration Statement shall have been issued and no proceedings
         for that purpose shall have been instituted or threatened.

                  (iii) Subsequent to the execution and delivery of this
         Agreement, there shall have not 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 each 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 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; (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 each Underwriter, 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.

                  (iv) The Underwriters shall have received an opinion, dated
         the Closing Date, of Andrews & Kurth L.L.P., counsel of the Company,

                  actions, proceedings or investigations pending or threatened
                  before any court, administrative agency or other tribunal (1)
                  asserting the invalidity of this Agreement, the Trust
                  Agreement, the Servicing Agreement, the Purchase Agreement,
                  the Administration Agreement

                  FOR WHICH A PARTNERSHIP ELECTION IS MADE" and TRUSTS TREATED

                  headings "SUMMARY OF TERMS -- Federal Income Tax Status" and
                  "CERTAIN FEDERAL INCOME TAX CONSEQUENCES";

                           (f) This Agreement, the Trust Agreement, the
                  Servicing Agreement, the Purchase Agreement, the

                  each been duly authorized, executed and delivered by the
                  Company;

                           (g) The Contracts constitute "chattel paper" as
                  defined in Section 9105(a)(2) of the Uniform Commercial Code

                           (h) The statements in the Prospectus under the
                  caption "CERTAIN LEGAL ASPECTS OF THE CONTRACTS," and "ERISA
                  CONSIDERATIONS" to the extent they constitute matters of
                  California or federal law or legal conclusions, are correct in
                  all material respects;

                           (i) The direction by the Company to the Trust Agent
                  to authenticate the Certificates has been duly authorized by
                  the Company and, when the Certificates have been duly executed
                  by the Owner Trustee and authenticated and delivered by the
                  Trust Agent in accordance with the Trust Agreement and
                  delivered and paid for pursuant to this Agreement, will be
                  duly and validly issued and outstanding, and will be entitled
                  to the benefits of the Trust Agreement.

                           (j) When the Notes have been duly executed by the
                  Owner Trustee and delivered by the Trust Agent on behalf of

                  accordance with the Indenture and delivered and paid for
                  pursuant to this Agreement, the Notes will be the valid, legal
                  and binding obligations of the Trust, enforceable against the
                  Trust in accordance with their terms, subject to 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);

                           (k) Assuming the authorization, execution and
                  delivery thereof by each party thereto other than the Company
                  and Onyx, each of the Trust Agreement, the Purchase Agreement,
                  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,


                                       13
<PAGE>   14

                  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 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,


                                       14

                  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 Contracts and (ii) as to the existence of a valid, perfected,
first priority security interest in the 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

                  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

                  applicable, or the transfer of the 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,
                  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


                                       16

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,
schedules and the other financial and statistical data included in the
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 Contracts by Onyx to the
         Company as a sale and with respect to the perfection of the Trust's
         interests in the 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.

                  and the Class I Notes should 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
                  heading "SUMMARY OF TERMS -- Tax Status"; "CERTAIN FEDERAL
                  INCOME TAX CONSEQUENCES"; "TRUSTS FOR WHICH A PARTNERSHIP
                  ELECTION IS MADE" and "TRUSTS TREATED AS GRANTOR TRUSTS" and

                  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.

                  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

                  Agreement against the Insurer, is required in connection with

                  MBIA Indemnification Agreement have been duly authorized,

                  moratorium and other similar laws relating to or affecting the
                  enforcement of creditors' rights generally, including, without
                  limitation, laws relating to fraudulent transfers or
                  conveyances, preferential transfers and equitable
                  subordination, presently or from time to time in effect and

                  law), as such laws may be applied in any such proceeding with
                  respect to the Insurer and (2) the qualification that the

                  under the Securities Act of 1933, as amended.

         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 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,


                                       21
<PAGE>   22

         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.

         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


                                       22
<PAGE>   23

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 Chase Securities Inc, 270 Park Avenue, 7th
Floor, New York, New York 10017 Attention: Asset Backed Securities Group, or to
such other address as the Representative may designate in writing to the
Company, or if sent to Salomon Smith Barney, Inc., will be mailed, delivered or
telegraphed, and confirmed to it at Salomon Smith Barney Inc., 390 Greenwich
Street, New York, New York 10013 Attention: Asset-Backed Group, or to such other
address as the Representative may designate in writing to the Company, or if
sent to the Company, will be mailed, delivered or telegraphed and confirmed to
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 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


                                       23
<PAGE>   24

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 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.

        Each Note shall be dated the date of its authentication. The Notes shall
be issuable as registered Notes in the minimum denomination of $1,000 and in
integral multiples of $1,000 in excess thereof, except that one Note of each
Class may be issued in a different denomination.

        No Note shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose, unless there appears on such Note a
certificate of authentication substantially in the form provided for in the
forms of Notes attached as exhibits to this Indenture executed by the Indenture
Trustee by the manual signature of one of its authorized signatories, and such
certificate upon any Note shall be conclusive evidence, and the only evidence,
that such Note has been duly authenticated and delivered hereunder.

                Section 2.03 Temporary Notes. Pending the preparation of
definitive Notes, the Issuer may execute, and upon receipt of an Issuer Order
the Indenture Trustee shall authenticate and deliver, temporary Notes that are
printed, lithographed, typewritten, mimeographed or otherwise produced, of the
tenor of the definitive Notes in lieu of which they are issued and with such
variations not inconsistent with the terms of this Indenture as the officers
executing such Notes may determine, as evidenced by their execution of such
Notes.

        If temporary Notes are issued, the Issuer will cause definitive Notes to
be prepared without unreasonable delay. After the preparation of definitive
Notes, the temporary Notes shall be exchangeable for definitive Notes upon
surrender of the temporary Notes at the office or agency of the Issuer to be
maintained as provided in Section 3.02, without charge to the Holder. Upon
surrender for cancellation of any one or more temporary Notes, the Issuer shall
execute and the Indenture Trustee shall authenticate and deliver in exchange
therefor a like tenor and principal amount of definitive Notes of authorized
denominations. Until so exchanged, the temporary Notes shall in all respects be
entitled to the same benefits under this Indenture as definitive Notes.

                Section 2.04 Registration; Registration of Transfer and
Exchange. The Issuer shall cause to be kept a register (the "NOTE REGISTER") in
which, subject to such reasonable regulations as it may prescribe, the Issuer
shall provide for the registration of Notes and the registration of transfers of
Notes. The Indenture Trustee shall be "NOTE REGISTRAR" for the purpose of
registering Notes and transfers of Notes as herein provided. Upon any
resignation of any Note Registrar, the Issuer shall promptly appoint a successor
or, if it elects not to make such an appointment, assume the duties of Note
Registrar.

        If a Person other than the Indenture Trustee is appointed by the Issuer
as Note Registrar, the Issuer will give the Indenture Trustee prompt written
notice of the appointment of such Note Registrar and of the location, and any
change in the location, of the Note Register, and the Indenture


                                      -9-

Trustee shall have the right to inspect the Note Register at all reasonable
times and to obtain copies thereof, and the Indenture Trustee shall have the
right to rely upon a certificate executed on behalf of the Note Registrar by an
Executive Officer thereof as to the names and addresses of the Holders of the
Notes and the principal amounts and number of such Notes.

        Upon surrender for registration of transfer of any Note at the office or
agency of the Issuer to be maintained as provided in Section 3.02, the Issuer
shall execute, and the Indenture Trustee shall authenticate and the Noteholder
shall obtain from the Indenture Trustee, in the name of the designated
transferee or transferees, one or more new Notes of the same Class in any
authorized denominations, of a like aggregate principal amount.

        At the option of the Holder, Notes may be exchanged for other Notes of
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,
and the Indenture Trustee shall authenticate and the Noteholder shall obtain
from the Indenture Trustee, the Notes which the Noteholder making the exchange
is entitled to receive.

        All Notes issued upon any registration of transfer or exchange of Notes
shall be the valid obligations of the Issuer, evidencing the same debt, and
entitled to the same benefits under this Indenture, as the Notes surrendered
upon such registration of transfer or exchange.

        Every Note presented or surrendered for registration of transfer or
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
signature guaranteed by a commercial bank or trust company located, or having a
correspondent located, in the city of New York or the city in which the
Corporate Trust Office is located, or by a member firm of a national securities
exchange, and such other documents as the Indenture Trustee may require.

        No service charge shall be made to a Holder for any registration of
transfer or exchange of Notes, but the Issuer or the Indenture Trustee may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any registration of transfer or
exchange of Notes, other than exchanges pursuant to Section 2.03 or 9.06 not
involving any transfer.

        The preceding provisions of this Section notwithstanding, the Issuer
shall not be required to make and the Note Registrar need not register transfers
or exchanges of Notes selected for redemption or of any Note for a period of 15
days preceding the due date for any payment with respect to the Note.

                Section 2.05 Mutilated, Destroyed, Lost or Stolen Notes. If (i)
any mutilated Note is surrendered to the Indenture Trustee, or the Indenture
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


                                      -10-

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.

                Section 2.06 Persons Deemed Owner. Prior to due presentment for
registration of transfer of any Note, the Issuer, the Indenture Trustee, the
Insurer and any of their respective agents may treat the Person in whose name
any Note is registered (as of the day of determination) as the owner of such
Note for the purpose of receiving payments of principal of and interest, if any,
on such Note and for all other purposes whatsoever, whether or not such Note be
overdue, and none of the Issuer, the Insurer, the Indenture Trustee nor any of
their respective agents shall be affected by notice to the contrary.

                Section 2.07 Payment of Principal and Interest; Defaulted
Interest.

                (a) Each Class of Notes shall accrue interest during each
Interest Accrual Period at the related Interest Rate, and such interest shall be

                                      -11-
<PAGE>   17

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 a Class A 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 Class A 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 Class A Note shall be payable on each
Distribution Date to the extent provided in the form of the related Class A Note
set forth as an Exhibit hereto. Notwithstanding the foregoing, the entire unpaid
principal amount of the Notes of a Class of Class A 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 Class A Notes representing not less than
        662/3% of the Outstanding Amount of the Class A Notes have declared the
        Notes to be immediately due and payable in the manner provided in
        Section 5.02.

All principal payments on each Class of Class A 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, if any, 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


                                      -12-
<PAGE>   18

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 Class A 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, if any, 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:

                        (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;

                        (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

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

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

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 2.13 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.

                                    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, (iv) the Class A-4 Notes, to the Class A-4 Noteholders and (v) the
Class I Notes, to the Class I 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 Collection Account, the Payment Account and the Note Distribution
Account shall be made on behalf of the Issuer by the Indenture Trustee or by
another Paying Agent, and no amounts so withdrawn from the Collection Account,
the Payment Account and 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


                                      -16-
<PAGE>   22

                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:


                                      -17-
<PAGE>   23

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

                        (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 Cut Off 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 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


                                      -19-

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 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


                                      -20-

                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.

                Section 3.09 Annual Statement as to Compliance. The Issuer will
deliver to the Indenture Trustee and the Insurer, on or before 120 days after
the end of each fiscal year of the Issuer (commencing with the fiscal year ended
December 31, 1999), an Officer's Certificate stating, as to the Authorized
Officer signing such Officer's Certificate, that:

                        (i) a review of the activities of the Issuer during such
                year and of performance under this Indenture has been made under
                such Authorized Officer's supervision; and

                        (ii) to the best of such Authorized Officer's knowledge,
                based on such review, the Issuer has complied with 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 status thereof.

                Section 3.10 Issuer May Consolidate, etc. Only on Certain Terms.

                (a) The Issuer shall not consolidate or merge with or into any
other Person, unless:

                        (i) the Person (if other than the Issuer) formed by or
                surviving such consolidation or merger shall be a Person
                organized and existing under the laws of the United States or
                any State and shall expressly assume, by an indenture
                supplemental hereto, executed and delivered to the Indenture
                Trustee and the Insurer, in form and substance satisfactory to
                the Indenture Trustee and the Insurer (so long as no Insurer
                Default shall have occurred and be continuing), the due and
                punctual payment of the principal of and interest on all Notes
                and the performance or observance of every agreement and
                covenant of this Indenture and each other Basic Document on the
                part of the Issuer to be performed or observed, all as provided
                herein;

                        (ii) immediately after giving effect to such
                consolidation or merger, no Default or Event of Default shall
                have occurred and be continuing;

                        (iii) the Rating Agency Condition shall have been
                satisfied with respect to such consolidation or merger;

                        (iv) the Issuer shall have received an Opinion of
                Counsel which shall be delivered to and shall be satisfactory to
                the Indenture Trustee and the Insurer to the effect that such
                consolidation or merger will not have any material adverse tax
                consequence to the Trust, the Insurer, any Noteholder or any
                Certificateholder;

                                   ARTICLE IV

                                    of redemption by the Indenture Trustee in

Certificate from a firm of certified public accountants, each meeting the

                                    ARTICLE V

                           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 Class A Notes on the Final Scheduled Distribution Date for such Class
of Class A 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 Highest Priority Class, 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


                                      -26-
<PAGE>   32

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 Highest
Priority Class, 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

                (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 Class A 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 (i) the unpaid principal amount of the Class A Notes,
together with accrued and unpaid interest thereon and (ii) the Imputed Principal
Balance of the Class I Notes, together with accrued and unpaid interest on the
Notional Principal Amount of the Class I Notes, 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


                                      -27-
<PAGE>   33

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 Highest Priority
Class, upon prior written notice to each Rating Agency, declare that all the
Notes become immediately due and payable, and upon any such declaration (i) the
unpaid principal amount of the Class A Notes, together with accrued and unpaid
interest thereon, and (ii) the Imputed Principal Balance of the Class I Notes,
together with accrued and unpaid interest on the Notional Principal Amount of
the Class I Notes, 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.

                (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
Highest Priority Class, 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


                                      -28-

                counsel, and for reimbursement of all expenses and liabilities
                incurred by the Indenture Trustee and each predecessor Indenture

                and

                        (iv) to file such proofs of claim and other papers or
                documents as may be necessary or advisable in order to have the

                in any judicial proceedings relative to the Issuer, its
                creditors and its property;

and any trustee, receiver, liquidator, custodian or other similar official in

behalf of any Noteholder any plan of reorganization, arrangement, adjustment or

                (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


                                      -29-

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

                with respect thereto, whether by declaration or otherwise,

                        (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


                                      -30-
<PAGE>   36

                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 Class A Notes and the
                Imputed Principal Balance and all accrued interest on the Class
                I 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 Highest Priority Class,
                such 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 Class A Notes, the Imputed
                Principal Balance of and all accrued interest on the Class I
                Notes, all outstanding principal of and accrued interest on 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 and, if Holders of Class A Notes are
                directing the Indenture Trustee, the Holders of 100% of the
                Outstanding Amount of the Class I Notes, 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,


                                      -31-
<PAGE>   37

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 Holders of Class A Notes, to pay accrued
                interest on each Class of Class A 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 Class A Notes at
                the related Interest Rate for such Class;

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

                        fifth, to the Holders of Class I Notes, to pay accrued
                interest on the Class I Notes (including, to the extent
                permitted by applicable law, interest accrued on any interest
                accrued but not timely paid) at the Interest Rate for the Class
                I Notes;

                        sixth, to the Holders of Class I Notes to pay the
                Imputed Principal Balance, until the Imputed Principal Balance
                is reduced to zero;

                        seventh, 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;

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

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


                                      -32-

                        tenth, any excess amounts remaining after making the
                distributions described in clauses first through ninth 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 Highest Priority Class 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 Highest Priority Class, 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
of the Highest Priority Class, each representing less than a majority of the
Outstanding Amount of such Highest Priority Class, the Indenture Trustee shall
act at the request of the Holders of such Highest Priority Class with the
greater Outstanding Amount of such Highest Priority Class; provided, however
that if such groups


                                      -33-
<PAGE>   39

of Holders of such Notes have the same Outstanding Amount of such Highest
Priority Class, 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, in the case of a Class A Note, payment of the
principal of and interest on such Class A Note, and in the case of a Class I
Note, payment of interest on such Class I 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 Class A 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 Highest Priority Class 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;


                                      -34-
<PAGE>   40

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

                        (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 Highest Priority Class, 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


                                      -35-

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 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 662/3% of the Outstanding Amount of the Highest
Priority Class 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


                                      -36-
<PAGE>   42

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:

                        (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.


                                      -37-
<PAGE>   43

                (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.

                (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


                                      -38-
<PAGE>   44

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 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.


                                      -39-
<PAGE>   45

                (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


                                      -40-
<PAGE>   46

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.

        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


                                      -41-
<PAGE>   47

                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.

        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


                                      -42-
<PAGE>   48

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.

                (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


                                      -43-

                        (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.

                (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.

Indenture Trustee may demand payment or delivery of, and shall receive and

other intermediary, all money and other property payable to or receivable by the

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

                (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

Collections available with respect to such Distribution Date and deposited into

withdrawn from the Spread Account or representing payment of the Policy Claim
Amount, to make the deposits to the Note Distribution Account required pursuant

                Distributable Amount to the extent of the remaining Outstanding
                Amount of such Class of Class A Notes;

                        (iii) to the Holders of Class I Notes, the Note Interest

                above), until the Outstanding Amount of the Class A-2 Notes is

                effect to the payments, if any, described in clauses (ii),
                (iii), (iv) and (v) above), until the Outstanding Amount of the
                Class A-3 Notes is reduced to zero; and

                      (vii) to the Holders of the Class A-4 Notes, the remaining

                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 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.

                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,

material respect the interests of any Noteholder.

Noteholders. The Issuer and the Indenture Trustee, when authorized by an Issuer

                (d) modify or alter the provisions of the second proviso to the
definition of the term "Outstanding";


                                      -50-
<PAGE>   56

                (e) reduce the percentage of the Outstanding Amount of the
Notes, the consent of the Holders of which is required to direct the Indenture
Trustee to sell or liquidate the Collateral pursuant to Section 5.04;

                (f) decrease the percentage of the Outstanding Amount of the
Notes required to amend this Indenture or the other Basic Documents;

                (g) permit the creation of any lien ranking prior to or on a
parity with the lien created by this Indenture with respect to any part of the
Collateral or, except as otherwise permitted or contemplated herein, terminate
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, and subject
to Sections 6.01 and 6.02 shall be fully protected in relying upon, an Opinion
of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture. The Indenture Trustee may, but shall
not be obligated to, enter into any such supplemental indenture that affects the
Indenture Trustee's own rights, duties, liabilities or immunities 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,
limitations of rights, obligations, duties, liabilities and immunities under
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.

                Section 9.05 Conformity With Trust Indenture Act. Every
amendment of this Indenture and every supplemental indenture executed pursuant
to this Article shall conform to the requirements of the Trust Indenture Act as
then in effect so long as this Indenture shall then be qualified under the Trust
Indenture Act.

                Section 9.06 Reference in Notes to Supplemental Indentures.
Notes authenticated and delivered after the execution of any supplemental
indenture pursuant to this Article may, and if required by the Indenture Trustee
shall, bear a notation in form approved by the Indenture Trustee as to any
matter provided for in such supplemental indenture. If the Issuer or the
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.

                                    ARTICLE X

                           REDEMPTION OF CLASS A 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 Class A 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 Class A 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 Class A Notes to be redeemed whereupon all
such Class A 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 Class
A 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 Class A 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 Class
A 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


                                      -52-
<PAGE>   58

                        (iii) the place where such Class A Notes are to be
                surrendered for payment of the Redemption Price (which shall be
                the office or agency of the Issuer to be maintained as provided
                in Section 3.02).

        Notice of redemption of the Class A 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 Class A Note
shall not impair or affect the validity of the redemption of any other Class A
Note.

                Section 10.03 Notes Payable on Redemption Date. The Class A
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.

                                   ARTICLE XI

                                  MISCELLANEOUS

                Section 11.01 Compliance Certificates and Opinions, etc.

                (a) Upon any application or request by the Issuer to the
Indenture Trustee to take any action under any provision of this Indenture, the
Issuer shall furnish to the Indenture Trustee (i) an Officer's Certificate
stating that all conditions precedent, if any, provided for in this Indenture
relating to the proposed action have been complied with, (ii) an Opinion of
Counsel stating that in the opinion of such counsel all such conditions
precedent, if any, have been complied with and (iii) (if required by the TIA) an
Independent Certificate from a firm of certified public accountants meeting the
applicable requirements of this Section. Notwithstanding the foregoing, in the
case of any such application or request as to which the furnishing of such
documents is specifically required by any provision of this Indenture, no
additional certificate or opinion need be furnished.

        Every certificate or opinion with respect to compliance with a condition
or covenant provided for in this Indenture shall include:

                        (i) a statement that each signatory of such certificate
                or opinion has read or has caused to be read such covenant or
                condition and the definitions herein relating thereto;

                        (ii) a brief statement as to the nature and scope of the
                examination or investigation upon which the statements or
                opinions contained in such certificate or opinion are based;

                        (iii) a statement that, in the opinion of each such
                signatory, such signatory has made such examination or
                investigation as is necessary to enable such signatory


                                      -53-
<PAGE>   59

                to 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 each
                such signatory, such condition or covenant has been complied
                with.

                (b) (i) Prior to the deposit of any Collateral or other property
or securities with the Indenture Trustee that is to be made the basis for the
release of any property subject to the lien created by this Indenture, the
Issuer shall, in addition to any obligation imposed in Section 11.01(a) or
elsewhere in this Indenture, furnish to the Indenture Trustee and the Insurer an
Officer's Certificate certifying or stating the opinion of the signer thereof as
to the fair value (within 90 days of such deposit) to the Issuer of the
Collateral or other property or securities to be so deposited.

               (ii) Whenever the Issuer is required to furnish to the Indenture
        Trustee and the Insurer an Officer's Certificate certifying or stating
        the opinion of any signer thereof as to the matters described in clause
        (i) above, the Issuer shall also deliver to the 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 Class A Notes, but such Officer's Certificate need not be furnished
        with respect to any property so deposited, if the fair value thereof to
        the Issuer as set forth in the related Officer's Certificate is less
        than $25,000 or less than one percent of the Outstanding Amount of the
        Class A Notes.

               (iii) Whenever any property or securities are to be released from
        the lien created by this Indenture, the Issuer shall also furnish to the
        Indenture Trustee and the Insurer an Officer's Certificate certifying or
        stating the opinion of each person signing such certificate as to the
        fair value (within 90 days of such release) of the property or
        securities proposed to be released and stating that in the opinion of
        such person the proposed release will not impair the security created by
        this Indenture in contravention of the provisions hereof.


               (iv) Whenever the Issuer is required to furnish to the Indenture
        Trustee and the Insurer an Officer's Certificate certifying or stating
        the opinion of any signer thereof as to the matters described in clause
        (iii) above, the Issuer shall also furnish to the 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 Class A 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 Class A 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


                                      -54-
<PAGE>   60

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
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.


                                      -55-
<PAGE>   61

                (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-C, 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

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

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.

        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.

                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,

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

the Seller or the Issuer of, any bankruptcy, reorganization, arrangement,

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


                                      -59-
<PAGE>   65

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

of the Trust Estate.

        (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 Date through the current Distribution Date, (C) the portion

        price and (D) any other amounts of income payable to the
        Certificateholders for such month; such sum to be reduced by 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.

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 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

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 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 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 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
to Certificate Owners pursuant to Section 3.13, (i) each party required or
desiring to give such notice shall furnish such notice to the Trust Agent and
(ii) the Owner Trustee shall give any notices referred to in the preceding
clause (i) and any notices which it is required or desires to give hereunder to
the Clearing Agency.

        Section 3.13 Definitive Trust Certificates. If (i)(A) the Seller or the
Administrator advises the Owner Trustee or the Trust Agent in writing that the
Clearing Agency is no longer willing or able to properly discharge its
responsibilities as described in the Depository Agreement and (B) the Seller,
the Owner Trustee, the Trust Agent or the Administrator is unable to locate a
qualified successor, or (ii) after the occurrence of an Event of Default or a
Servicer Default, Certificate Owners representing in the aggregate more than 50%
of the Certificate Balance advise the Owner Trustee (and if the Owner Trustee
receives such advice it shall promptly notify the Trust Agent) or the Trust
Agent 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 Certificate Owners, then the Trust Agent shall notify all
Certificate Owners of the availability through the Clearing Agency of Definitive
Trust Certificates to Certificate Owners requesting the same. Upon surrender to
the Trust Agent by the Clearing Agency of the Certificate or Certificates
evidencing the Book-Entry Trust Certificates by the Clearing Agency,
accompanied by registration instructions from the Clearing Agency, the Owner
Trustee on behalf of the Trust shall execute and the Trust Agent shall
authenticate the Definitive Trust Certificates and deliver such Definitive Trust
Certificates in accordance with the instructions of the Clearing Agency. Neither
the Depositor, the Certificate Registrar, the Owner Trustee nor the Trust Agent
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 Trust Certificates, the Owner Trustee and the
Trust Agent shall recognize the Holders of the Definitive Trust Certificates as
Certificateholders hereunder. Neither the Owner Trustee nor the Trust Agent
shall be liable if the Owner Trustee, the Trust Agent or the Administrator is
unable to locate a qualified successor Clearing Agency. The Definitive Trust
Certificates shall be printed, lithographed or engraved or may be produced in
any manner as is reasonably acceptable to the Owner Trustee, as evidenced by its
execution thereof.

        (a) Each prospective purchaser and any subsequent transferee of a
Residual Interest Instrument (each, a "PROSPECTIVE OWNER"), other than the
Depositor, by virtue of its acceptance thereof, shall be deemed to have
represented and warranted to the Owner Trustee, the Trust Agent and the
Certificate Registrar and any of their respective successors that:

               (i) Such Person is (A) a "QUALIFIED INSTITUTIONAL BUYER" as

        the account of one or more qualified institutional buyers for whom it is

        Instruments have not been and will not be registered under the
        Securities Act and may be offered, sold, pledged or otherwise
        transferred only to a person whom the seller reasonably believes is (A)
        a qualified institutional buyer (as such term is defined in Rule 144A
        under the Securities Act) or (B) a Person involved in the organization
        or operation of the Trust or an affiliate of such Person, in a
        transaction meeting the requirements of Rule 144A under the Securities
        Act and in accordance with any applicable securities laws of any state
        of the United States.

               (iii) Such person understands that the Residual Interest
        Instrument bears a legend to the following effect:

                   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-C, 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.

Trustee, shall direct the Paying Agent to distribute to the Certificateholders

<PAGE>   24

        (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
made by check mailed to such Owner at the address of such Holder appearing in
the Certificate Register (or, if DTC, its nominee or a Clearing Agency is the
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

with respect to the Basic Documents.

        Section 6.02 General Duties. Subject to the provisions and limitations

        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.

ownership or the administration of the Trust Estate or the Grant of any portion
thereof to the Indenture Trustee pursuant to the Indenture.

        (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.

        (e) Upon the winding up of the Trust and its termination, the Owner
Trustee shall cause the Certificate of Trust to be canceled by filing a
certificate of cancellation with the Secretary of State in accordance with the
provisions of Section 3810 of the Business Trust Statute.

                   SUCCESSOR OWNER TRUSTEES, ADDITIONAL OWNER
                             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.



                                      -30-

<PAGE>   35

        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, 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



                                      -31-

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 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,



                                      -32-

<PAGE>   37

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 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.

        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

effect,

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

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
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

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

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.

Contract whereby interest due is calculated each day based on the actual

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.

        (b) 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

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.

        (c) 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

                                      -22-
<PAGE>   27

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.

        (d) 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.

        (e) 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.

        (f) 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.

        (g) 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
the Contracts and in connection with maintaining the first priority security
interest (subject to the security interest of the Insurer pursuant to the
Insurance Agreement) in the Financed Vehicles and the proceeds thereof.

                             the creation or imposition of any Lien upon any of
                             the properties of the Seller pursuant to the terms
                             of any such indenture, agreement, or other
                             instrument (other than pursuant to the Basic

                             seeking any determination or ruling that might
                             materially and adversely affect the performance by

        (b) As to each Contract (except as noted below as being applicable only
to either Precomputed Contracts or Simple Interest Contracts):

                      (i)    The information pertaining to such Contract set
                             forth in the related Schedule of Contracts was true
                             and correct in all material respects at the Closing
                             Date.

                      (ii)   As of the Closing Date, such Contract was secured
                             by a valid and enforceable first priority security
                             interest in favor of Onyx or a subsidiary of Onyx
                             in the related Financed Vehicle, and such security
                             interest has been duly perfected and is prior to
                             all other liens upon and security interests in such
                             Financed Vehicle which now exist or may hereafter
                             arise or be created (except, as to priority, for
                             any lien for unpaid taxes or unpaid storage or
                             repair charges which may arise after the Closing
                             Date in accordance with the UCC); such security
                             interest is assignable, had been assigned by Onyx
                             to the Seller pursuant to the Purchase Agreement,
                             and, as of the Closing Date, has been assigned by
                             the Seller to the Issuer pursuant to Section
                             2.01(a) hereof.

                      (iii)  (A) If the related Financed Vehicle was originated
                             in a state in which notation of a security interest
                             on the Title Document (or in the electronic title
                             records, in the case of the State of California) is
                             required or permitted to perfect such security
                             interest, the Title Document or the electronic
                             title records for such Financed Vehicle shows, or,
                             if a new or replacement Title Document is being
                             applied for with respect to such Financed Vehicle,
                             the Title Document will be received within 180 days
                             of the Closing Date and will show, Onyx or a
                             subsidiary of Onyx named as the original secured
                             party under the related Contract as the Holder of a
                             first priority security interest in such Financed
                             Vehicle, and (B) if the related Financed Vehicle
                             was originated in a state in which the filing of a
                             financing statement under the UCC is required to
                             perfect a security interest in motor vehicles, such
                             filings or recordings have been duly made and show
                             Onyx or a subsidiary of Onyx named as the original
                             secured party under the related Contract, and in
                             either case, the Indenture Trustee on behalf of the
                             Securityholders and the Insurer has the same rights
                             as such secured party has or would have (if such
                             secured party were still the owner of such
                             Contract) against all parties claiming an interest
                             in such Financed Vehicle. With respect to each
                             Contract for which the Title Document has not yet
                             been returned from the Registrar of Titles (or
                             evidenced in the electronic title records, in the
                             case of the State of California), Onyx has written
                             evidence that such Title Documents showing Onyx or
                             a subsidiary of Onyx as first lienholder have been
                             applied for.

                      (iv)   As of the Closing Date, the Seller had good and
                             marketable title to and was the sole owner of each
                             Contract to be transferred to the Issuer pursuant
                             to Section 2.01 free of liens, claims, encumbrances
                             and rights of others and, upon transfer of such
                             Contract to the Issuer pursuant to Section 2.01,
                             the Issuer will have good and marketable title to,
                             will have a first priority perfected security
                             interest in and will be the sole owner of such
                             Contract free of liens, encumbrances and rights of
                             others.

                      (v)    As of the Cut-Off Date, the most recent scheduled
                             payment due on each such Contract had been made or
                             was not delinquent more than 30 days and, to the
                             best of the Seller's knowledge, all payments on the
                             Contract were made by the related Obligors.

                      (vi)   As of the Closing Date, there is no lien against
                             the related Financed Vehicle for delinquent taxes.

                      (vii)  As of the Closing Date, there is no right of
                             rescission, offset, defense or counterclaim to the
                             obligation of the related Obligor(s) to pay the
                             unpaid principal or interest due under such
                             Contract; the operation of

                             the terms of such Contract or the exercise of any
                             right thereunder will not render such Contract
                             unenforceable in whole or in part or subject such
                             Contract to any right of rescission, offset,
                             defense or counterclaim, and the Seller has no
                             knowledge that such right of rescission, offset,
                             defense or counterclaim has been asserted or
                             threatened.

                      (viii) As of the Closing Date, to the best of the Seller's
                             knowledge, there are no liens or claims which have
                             been filed, including liens for work, labor,
                             material, storage or unpaid taxes affecting the
                             related Financed Vehicle which are or may become a
                             lien prior to, or equal or coordinate with, the
                             security interest granted by such Contract.

                      (ix)   Such Contract, and the sale of the Financed Vehicle
                             sold thereunder, complied, at the time it was made,
                             in all material respects with all applicable
                             federal, state and local laws (and regulations
                             thereunder), including without limitation usury,
                             equal credit opportunity, fair credit reporting,
                             truth-in-lending or other similar laws, the Federal
                             Trade Commission Act, the Fair Debt Collection

                             Consumer Credit Code, and other applicable state
                             laws regulating retail installment sales contracts
                             and loans in general and motor vehicle retail

                             the consummation of the transactions herein
                             contemplated, including, without limitation, the
                             transfer of ownership of the Contracts to the
                             Issuer and the receipt of interest by the
                             Securityholders, will not violate any applicable
                             federal, state or local law.

                      (x)    Such Contract is the legal, valid and binding
                             obligation of the related Obligor(s) thereunder and
                             is enforceable in accordance with its terms, except
                             only as such enforcement may be limited by
                             bankruptcy, insolvency or similar laws affecting
                             the enforcement of creditors' rights generally;

                             to execute and deliver such Contract and all other
                             documents related thereto and to grant the security
                             interest purported to be granted thereby; the terms
                             of such Contract have not been waived, amended or
                             modified in any respect, except by instruments that
                             are part of the related Contract Documents, and no
                             such waiver, amendment or modification has caused
                             such Contract to fail to meet all of the
                             representations, warranties and conditions, set
                             forth herein with respect thereto.

                             for the practical realization against the
                             collateral of the benefits of the security,
                             subject, as to enforceability, to bankruptcy,
                             insolvency, reorganization or similar laws
                             affecting the enforcement of creditors' rights
                             generally.

                             that with notice or lapse of time would constitute
                             a default, breach, violation or event permitting
                             acceleration existing under such Contract, and (c)
                             the Seller has not waived any such default, breach,
                             violation or event permitting acceleration except
                             payment delinquencies permitted by subparagraph (v)
                             above.

                      (xiii) At the Closing Date each related Financed Vehicle
                             will be covered by the Blanket Insurance Policy;

                             policy is in effect.

                      (xiv)  At the Closing Date, (a) such Contract will require
                             that the related Obligor(s) obtain and maintain in

                             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

                             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

                             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 the 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 related
                             Contract Documents, is being held by the Custodian;
                             provided, however, that upon the execution by the
                             Indenture Trustee and the Trust with the prior
                             written consent of the Insurer of a letter
                             agreement revocably appointing the Servicer as
                             Successor Custodian in accordance with Section
                             2.04, such original Contracts together with all
                             other Contract Documents may be held by the
                             Servicer.

                      (xviii)As of the Closing Date, the Servicer has clearly
                             marked its electronic records to indicate that such
                             Contract is 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 Cut-Off Date, the Seller has not received
                             notice that any Obligor under such Contract has
                             filed for bankruptcy.

                      (xxi)  As of the Cut-Off Date, such Contract had an
                             original maturity of not more than 72 months and
                             such Contract has a remaining maturity of 72 months
                             or less;

                      (xxii) The first payment under each Initial Contract is
                             due on or before September 15, 1999, and the first
                             payment under each Subsequent Contract is due on or
                             before October 5, 1999. Less than 50% of the
                             aggregate principal balance of the Subsequent
                             Contracts have a first payment due on or after
                             October 1, 1999.

                      (xxiii)As of the Cut-Off Date, such Contract has a

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

                      (xxv)  The related Obligor(s) were located in Arizona,

                             Oregon, Pennsylvania, South Carolina, Tennessee,
                             Texas, Virginia or Washington on the date of
                             origination of such Contract.

                      (xxvi) 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.

        (c) As to all of the Contracts:

                      (i)    The aggregate Outstanding Principal Balance payable
                             by Obligors of the Contracts as of the Cut-Off Date
                             equals the Original Pool Balance.

                      (ii)   As of the Cut-Off Date, approximately 15.71% of the
                             Outstanding Principal Balance of all Contracts is

                             Vehicles, and approximately 84.29% of the
                             Outstanding Principal Balance of all Contracts is
                             attributable to loans

                             involving used Financed Vehicles.

                      (iii)  As of the Cut-Off Date, the aggregate Outstanding
                             Principal Balance of all Contracts originated in
                             any single state, other than California, did not
                             equal or exceed 10%.

        (d) 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.

        (e) 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 shall survive the Closing Date 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


                                      -30-
<PAGE>   35

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.

                      (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.



                                      -31-

                      (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 owned or serviced
by it or any of its Affiliates, unless the Insurer requires such segregation.

        SECTION 2.05. DUTIES OF SERVICER RELATING TO THE CONTRACTS.

        (a) Safekeeping. The Servicer, in its capacity as servicer, shall hold
the Contract Files and any Contract Documents held by it in accordance with this
Agreement on behalf of the Issuer, the Indenture Trustee and the Insurer for the
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


                                      -32-
<PAGE>   37


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

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 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

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
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


                                      -34-
<PAGE>   39

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 Class A
Notes have not been paid in full, by the Holders of Class A Notes evidencing not
less than 25% of the outstanding principal amount of the Class A Notes, acting
together as a single Class, or by the Indenture Trustee without consideration of
the effect such termination would have on Holders of Class I Notes or
Certificateholders, (ii) if the Class A Notes have been paid in full, by the
Holders of Class I Notes evidencing not less than 25% of the Notional Principal
Amount of the Class I Notes, or the Indenture Trustee without consideration of
the effect such termination would have on Certificateholders, and (iii) if the
Class A Notes have been paid in full and the Notional Principal Amount has been
reduced to zero, 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 Contract in respect of which, in place of a Title
Document, the Custodian received on the Closing Date 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


                                      -35-
<PAGE>   40



records) within 180 days after the Closing Date with respect to the Contracts,
then the representation and warranty in Section 2.02(b)(iii) as to such
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 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.


                                      -36-
<PAGE>   41

        On the Closing Date, the Servicer shall deposit in the Collection
Account (i) all installments of Monthly P&I due on or after the 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 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 a Contract relates received on or after
the Cut-Off Date and at least two Business Days prior to the Closing 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
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 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,


                                      -37-
<PAGE>   42

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, 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


                                      -38-
<PAGE>   43

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 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, 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:

                      (i)    The Servicer (1) has been duly organized, is
                             validly existing and in good standing as a
                             corporation organized and existing under the laws
                             of the State of Delaware, (2) has qualified to do
                             business as a foreign corporation and is in good
                             standing in each jurisdiction where the character
                             of its properties or the nature of its activities
                             makes such qualification necessary, and (3) has
                             full power, authority and legal right to own its
                             property, to carry on its business as presently

result of such obligation shall not constitute a breach of this Section.

        The Indenture Trustee shall furnish or cause to be furnished to the
Servicer, the Insurer and the Seller, within 15 days after receipt by the
Indenture Trustee of a written request therefor from the Servicer, the Insurer
or the Seller, a list, in such form as the Servicer, the Insurer or the Seller

a copy of the communication that such Applicants propose to transmit, then the
Indenture Trustee shall, within five Business Days after the receipt of such

current list of Noteholders. Each Noteholder, by receiving and holding a Note,
agrees with the Servicer, the Seller and the Indenture Trustee that none of the

                          STATEMENTS TO SECURITYHOLDERS

        SECTION 4.01. ESTABLISHMENT OF TRUST ACCOUNTS.

        (a) Prior to the Closing Date, the Servicer shall open, at a depository
institution (which may be the same depository institution which is acting in the
capacity as Indenture Trustee), the following accounts:

                      (i)    an account denominated "Collection Account - OT
                             1999-C, The Chase Manhattan Bank, Indenture
                             Trustee" (the "COLLECTION ACCOUNT");

                      (ii)   an account denominated "Payahead Account - OT
                             1999-C, The Chase Manhattan Bank, as agent" (the
                             "PAYAHEAD ACCOUNT");

                      (iii)  an account denominated "Spread Account - OT 1999-C,
                             The Chase Manhattan Bank, Indenture Trustee" (the
                             "SPREAD ACCOUNT");

                      (iv)   an account denominated "Note Distribution Account -
                             OT 1999-C, The Chase Manhattan Bank, Indenture
                             Trustee" (the "NOTE DISTRIBUTION ACCOUNT"); and

                      (v)    an account denominated "Certificate Distribution
                             Account - OT 1999-C, The Chase Manhattan Bank,
                             Trust Agent" (the "CERTIFICATE DISTRIBUTION
                             ACCOUNT").

        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-C, The Chase Manhattan Bank, Indenture Trustee" (the
"PAYMENT ACCOUNT" and, together with the accounts described in clauses (i)
through (v) 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


                                      -48-
<PAGE>   53

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)
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 and the Spread 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 and the Spread 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 and the Spread Account in writing
(with a copy of such direction to the Indenture Trustee, if the Indenture
Trustee is not the applicable depository institution) to invest funds in the
Collection Account and the Spread 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 shall be deposited in or credited
to the Spread Account immediately upon receipt, and any loss resulting from such
investment shall be charged to the Spread Account. The maximum permissible
maturities of any investments of funds in the Collection Account and the Spread
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



                                      -49-
<PAGE>   54

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. 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 and the Collection 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 or the Spread 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.

        (e) On the Closing Date, Onyx shall deposit $2,000,000 into the Spread
Account.

        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 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 Servicer Report Date next succeeding (i) the end of
the Collection Period in which the applicable Contract is repurchased by the
Seller pursuant to Section 2.03, in the case of the Seller or (ii) the last day
of the related cure period specified in Section 3.07, in the case of the
Servicer.

        (b) On the Servicer Report Date, the Servicer shall determine the Policy
Claim Amount, if any, which exists with respect to the related Distribution Date
and submit a Distribution Date Statement pursuant to Section 3.09.

        (c) The Indenture Trustee shall, no later than 12:00 p.m., New York City
time, on the third Business Day prior to each Distribution Date (based solely on
the information contained in the Distribution Date Statement, delivered on the
applicable Servicer Report Date), make a claim under the Policy for the Policy
Claim Amount, if any, for such Distribution Date by delivering to the Fiscal
Agent, with a copy to the Insurer, the Trust Agent and the Servicer, by hand
delivery, telex or facsimile transmission, a written notice (a "DEFICIENCY
NOTICE") specifying the Policy Claim


                                      -50-
<PAGE>   55

Amount, if any, for such Distribution Date, separately identifying the amount of
the Policy Claim Amount payable in respect of each Class of Notes and the
Certificates. Each Deficiency Notice shall direct the Insurer to remit such
Policy Claim Amount to the Indenture Trustee for deposit in the Payment Account.
In making any such claim, the Indenture Trustee shall comply with all the terms
and conditions of the Policy. Upon receipt of the Policy Claim Amount, the
Indenture Trustee shall apply the portion thereof, if any, representing the
Deficiency Amount with respect to a Distribution Date as provided in Section
4.03(a). Any amounts received by the Indenture Trustee under the Policy that
represent Preference Amounts shall be paid, in accordance with the Policy, to
the applicable Noteholder(s) and Certificateholder(s).

        (d) So long as Onyx is the Servicer, the Servicer may make deposits in
or credits to the Collection Account net of amounts to be paid to the Servicer
under this Agreement. Notwithstanding the foregoing, the Servicer shall maintain
the records and accounts for such deposits and credits on a gross basis.

        (e) On the Business Day immediately preceding each Distribution Date,
based solely on the Distribution Date Statement, the Servicer shall cause funds
equal to the amount of Net Collections available with respect to such
Distribution Date on deposit in the Collection Account to be withdrawn from the
Collection Account and deposited into the Payment Account to be distributed
pursuant to Section 4.03(a).

        SECTION 4.03.        DISTRIBUTIONS.

        (a) On each Distribution Date, based solely on the Distribution Date
Statement, the Indenture Trustee will apply the Net Collections available from
the Payment Account with respect to such Distribution Date to make the following
deposits and distributions in the following amounts and order of priority:

                      (i)    to the Servicer, the Servicing Fee, including any

                      (ii)   to the Indenture Trustee, the Owner Trustee and the

                             not been previously paid by the Servicer;

                      (iii)  to the Note Distribution Account, the Class A Note

                      (vii)  to the Note Distribution Account, solely from Net
                             Collections remaining after giving effect to the
                             distributions described in clauses (i) through (vi)

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 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;

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 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.

        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 (vi) and (viii)
with respect to such Distribution Date exceeds the amount of Net


                                      -53-
<PAGE>   58

Collections 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 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,


                                      -54-
<PAGE>   59

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.

        SECTION 4.05. STATEMENTS TO SECURITYHOLDERS.

        (a) On each Distribution Date, (i) the Indenture Trustee shall include

                      (xv)   the number and net outstanding balance of Contracts
                             for which the Financed Vehicle has been

the Notional Principal Amount, the Regular Principal Distributable Amount will
be allocated (i) first, to the PAC Component up to the amount necessary to
reduce the PAC Component to its Planned Notional Principal Amount for such
Distribution Date, (ii) second, to the Companion Component until the balance
thereof is reduced to zero, and (iii) third, to the PAC Component without regard
to the Planned Notional Principal Amount for such Distribution Date.

entirety to any Person unless the corporation formed by such consolidation or
into which the Seller has merged or the Person which acquires by conveyance,
transfer or lease substantially all the assets of the Seller as an entirety, can

delivers to the Issuer, the Trust Agent, the Indenture Trustee and the Insurer
an agreement in form and substance reasonably satisfactory to the Issuer, the

                                  THE SERVICER

        SECTION 6.01. LIABILITY OF SERVICER; INDEMNITIES.

        Subject to Section 7.02, the Servicer shall be liable in accordance
herewith only to the extent of the obligations specifically undertaken by the
Servicer under this Agreement. Such obligations shall include the following:

        (a) The Servicer shall defend, indemnify and hold harmless the Issuer,
the Owner Trustee, the Trust Agent, the Indenture Trustee, the Insurer, the
Custodian, their respective officers, directors, agents and employees, and the
Securityholders from and against any and all costs, expenses, losses, damages,

        (b) 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 taxes that may at any time
be asserted against the Issuer, the Owner Trustee, the Trust Agent, the
Indenture Trustee, the Insurer or the Custodian with respect to the transactions
contemplated herein and in the other Basic Documents, including, without
limitation, any sales, gross receipts, general corporation, tangible personal
property, privilege or license taxes (but, not including (i) in the case of the
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
Securities) and costs and expenses in defending against the same.

        (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,
directors, agents and employees and the Securityholders from and against any and
all costs, expenses, losses, claims, damages and liabilities to the extent that
such cost, expense, loss, claim, damage or liability arose out of, or was
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


                                      -59-
<PAGE>   64

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
Delaware, and will obtain and preserve its qualification to do business as a
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



                                      -60-
<PAGE>   65

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.


                                      -61-
<PAGE>   66

        (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.

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

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

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 (i) the Indenture Trustee, or (ii) the
Issuer, or (iii) Holders of Class A Notes, acting together as a single Class,
evidencing in the aggregate not less than 25% of


                                      -63-
<PAGE>   68

the Notional Principal Amount of the Class I Notes, or (v) if the outstanding
amount of the Class A Notes has been reduced to zero and the Notional Principal
Amount has been reduced to zero, the Certificateholders evidencing in the
aggregate not less than 25% of the Certificate Balance, or (vi) 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

        (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 Class A Notes have not been paid in full, the Holders of Class A
Notes evidencing not less than 25% of the outstanding principal amount of the
Class A Notes, acting together as a single Class; or (B) if the Class A Notes
have been paid in full, Holders of the Class I Notes evidencing not less than
25% of the Notional Principal Amount of the Class I Notes; or (C) the Indenture
Trustee acting on behalf of the Class A Noteholders or the Class I Noteholders,
as the case may be, and not the Seller or the Certificateholders; or (D) if the
Class A Notes have been paid in full, the Notional Principal Amount has been
reduced to zero 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 Class A Notes have
not been paid in full, the Indenture Trustee shall be the Successor Servicer,
and (ii) if the Class A Notes have been paid in full and the Notional Principal
Amount has been reduced to zero, 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
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


                                      -65-
<PAGE>   70

is continuing, (i) the Holders of Class A Notes evidencing not less than 51% of
the outstanding principal amount of the Class A Notes, on behalf of all
Securityholders; or (ii) if all the Class A Notes have been paid in full,
Holders of Class I Notes evidencing not less than 51% of the Notional Principal
Amount of the Class I Notes, on behalf of all Securityholders; or (iii) if all
the Class A Notes have been paid in full, the Notional Principal Amount has been
reduced to zero 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 of Class A Notes evidencing 100% of
the outstanding principal amount of the Class A Notes or, if the Class A Notes
have been paid in full, Holders of Class I Notes evidencing 100% of the Notional
Principal Amount of the Class I Notes or, if the Class A Notes have been paid in
full and the Notional Principal Amount has been reduced to zero, 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 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.

        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 and the Notional Principal Amount of the Class
I Notes has been reduced to zero, 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 is 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.

                                  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
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 the Class A Notes are outstanding, the Holders of
Class A 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 Class A Notes have been paid in full and the Notional Principal Amount
has not been reduced to zero, the Holders of Class I Notes evidencing not less
than 51% of the Notional Principal Amount of the Class I Notes then outstanding
or (iii) if the Class A Notes have been paid in full and the Notional Principal
Amount has been reduced to zero, the Holders of Certificates evidencing not less
than 51% of the 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 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


                                      -68-

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

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