      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, the Prospectus and any Prospectus
      Supplement did or will comply in all material respects with the applicable
      requirements of the Act, the Exchange Act and the Trust Indenture Act of

      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, 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

      and is duly qualified to transact business as a foreign


                                       4
<PAGE>   5
      corporation in good standing under the laws of each jurisdiction where the
      ownership or leasing of its properties or the conduct of its business
      requires such qualification.

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

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

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

            (viii) The Company is not in violation of its Certificate of
      Incorporation or By-Laws or in default in the performance or observance of
      any obligation, agreement, covenant or condition contained in any
      agreement or instrument to which it is a party or by which it or its
      properties are bound which violation or default would have a material
      adverse effect on the transactions contemplated herein or in the
      Indenture, the Trust Agreement, the Servicing Agreement, the Purchase
      Agreement or the Insurance Agreements. The execution, delivery and
      performance by the Company of this Agreement, the Trust Agreement, the
      Servicing Agreement, the Purchase Agreement or the Insurance Agreements
      and the issuance and sale of the Notes 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 Notes as contemplated by this Agreement, to enter into this
      Agreement, the Trust Agreement, the Servicing Agreement, the Purchase
      Agreement and the Insurance Agreements and to consummate the transactions
      contemplated herein and therein.

            (ix) This Agreement has been, and the Servicing Agreement, the Trust
      Agreement, and the Insurance Agreements when executed and delivered as
      contemplated hereby and thereby will have been, duly authorized, executed
      and delivered by the Company, and this Agreement constitutes, and the
      Servicing Agreement, the Trust Agreement and the Insurance Agreements,
      when executed and delivered as contemplated herein, will constitute,
      legal, valid and binding instruments enforceable against the Company in
      accordance with their respective terms, subject as to enforceability to
      (x)


                                       5
<PAGE>   6
      applicable bankruptcy, reorganization, insolvency, moratorium or other
      similar laws affecting creditors' rights generally, (y) general principles
      of equity (regardless of whether enforcement is sought in a proceeding in
      equity or at law), and (z) with respect to rights of indemnity under this
      Agreement and the MBIA Indemnification Agreement limitations of public
      policy under applicable securities laws.

            (x) The Notes are duly and validly authorized by the Company and,
      when executed, authenticated and delivered in accordance with the
      Indenture and the Servicing Agreement, and issued and delivered to and
      paid for by the Underwriters, as contemplated hereby, will be entitled to
      the benefits provided by the Indenture and the Servicing Agreement.

            (xi) 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 Notes. 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 Notes 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.

      The Company will deliver the Notes 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

Underwriters and the Company determine, such time being herein referred to as
the "Closing Date". The Notes so to be delivered shall be represented by one or
more global notes 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, as applicable, representing the Notes
available for inspection by the Underwriters at the office at which the Notes
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
Notes for sale to the public (which may include selected brokers and dealers) as

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


                                       6
<PAGE>   7
            (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 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. None of the Underwriters shall have
      provided to any investor or prospective investor in the Notes 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 Notes 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


                                       7
<PAGE>   8
      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 Notes, 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 Notes 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
      Notes, 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 information in written or electronic form
      in connection with the offering of the Notes 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
      Notes covered thereby and the terms thereof not otherwise specified in the
      Basic Prospectus, the price at which such Notes 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


                                       8
<PAGE>   9
      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 Notes, 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 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 Notes 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 Noteholders and the holders of the
      Residual Interest Instruments of the Trust an earnings statement or
      statements of the Trust covering a


                                       9
<PAGE>   10
      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 Notes 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 Notes; 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
      Notes 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 Notes, the Company will furnish to the Underwriters
      copies of the annual statements of compliance delivered to the Indenture
      Trustee pursuant to Section 3.09 of the Indenture and Section 3.10 of the
      Servicing Agreement, and the annual independent public accountant's
      reports furnished to the Indenture Trustee pursuant to Section 3.11 of the
      Servicing Agreement, as soon as practicable after such statements and
      reports are furnished to the Indenture Trustee and Owner Trustee
      respectively.

            (x) So long as any of the Notes 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 Noteholders, (B) all
      documents filed, or caused to be filed, by the Company with the Commission
      pursuant to the Exchange Act, 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) (a) On or before the Closing Date the Company shall cause its
      computer records relating to the Funded Contracts to be marked to show the
      Trust's absolute ownership of the Funded Contracts and shall cause the
      Servicer to mark its computer records relating to the Funded Contracts to
      show the sale to the Company of the Funded Contracts and the subsequent
      transfer of the Funded Contracts to the Trust, and from and after the
      Closing Date the Company shall not, and shall instruct the Servicer not
      to, take any action inconsistent with the Trust's ownership of such Funded
      Contracts, other than as permitted by the Indenture and the Trust
      Agreement.


                                       10

            (b) On or before the related Prefunding Closing Date, the Company
      shall cause its computer records for the related Prefunded Contracts to be
      marked to show the Trust's absolute ownership of the related Prefunded
      Contracts and shall cause the Servicer to mark its computer records for
      the related Prefunded Contracts to show the sale to the Company of the
      related Prefunded Contracts and the subsequent transfer of the related
      Prefunded Contracts to the Trust, and after the related Prefunding Closing
      Date, the Company shall not, and shall instruct the Servicer not to, take
      any action inconsistent with the Trust's ownership of such Prefunded

      Agreement.

            (xii) The Company will file with the Commission as part of a current

      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

      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

      4(vi) as soon as practicable following receipt thereof.

      markets makes it impracticable or inadvisable to proceed with completion
      of the sale of, and any payment for, the Notes.

            (iv)  The Underwriters shall have received an opinion, dated

                                       13
<PAGE>   14
            consummation of any of the transactions contemplated by this
            Agreement, the Trust Agreement, the Servicing Agreement, the

            fraudulent or preferential conveyance and other similar laws of
            general application relating to or affecting creditors' rights

            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

                                       14
<PAGE>   15
            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;
            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 Notes, 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 Notes 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 Notes pursuant to this Agreement will not be, required to be
            registered under the Investment Company Act;

                  (r) The Indenture, the 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 the enforceability thereof may
            be subject to bankruptcy, insolvency, reorganization, moratorium,
            fraudulent or other preferential conveyance and other similar laws
            and other similar laws of general application relating to or
            affecting the rights of creditors generally and to general


                                       15
<PAGE>   16
            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 Notes have been duly taken or made; and

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

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

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

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

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

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

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


                                       16
<PAGE>   17
            authorizations, approvals, consents and orders which, in such
            counsel's experience, are normally applicable to transactions of the
            type contemplated by the Insurance Agreements, the Servicing
            Agreement, the Administration Agreement and the Purchase Agreement,
            as applicable;

                  (d) None of the execution, delivery and performance by Onyx of
            the Servicing Agreement, the Insurance Agreements, the
            Administration Agreement or the Purchase Agreement, as applicable,
            or the transfer of the 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 Agreements, the Administration Agreement and the Purchase
            Agreement, as applicable, each such agreement constitutes the legal,
            valid and binding agreement of Onyx, enforceable against Onyx in
            accordance with its terms, subject, as to enforcement, to (1) the
            effect of bankruptcy, insolvency, reorganization, moratorium,
            fraudulent or preferential conveyance and other similar laws of
            general application relating to or affecting creditors' rights
            generally and general principles of equity (regardless of whether
            such enforceability is considered in a proceeding in equity or at
            law); and (2) the unenforceability under certain circumstances of
            provisions indemnifying a party against liability where such
            indemnification is contrary to public policy.

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

      In addition, such counsel shall state that they have participated in
conferences with the officers and other representatives of the Company and Onyx,
representatives of the independent public accountants of the Company and Onyx

the Registration Statement and the Prospectus and related


                                       17

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).

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

                  (b) the Statements in the Base Prospectus under the heading

            CONSEQUENCES"; "TRUSTS FOR WHICH A PARTNERSHIP ELECTION IS MADE" and
            "TRUSTS TREATED AS GRANTOR TRUSTS" and in the Prospectus Supplement
            under the headings "SUMMARY OF TERMS -- Federal Income Tax Status"
            and "CERTAIN FEDERAL INCOME TAX CONSEQUENCES" to the extent that
            they constitute matters of law or legal conclusions with respect
            thereto, have been prepared or reviewed by such counsel and are
            correct in all material respects; and

            (ix) The Underwriters shall have received an opinion, dated the
      Closing Date, of Shaw, Pittman, Potts & Trowbridge, counsel to the
      Insurer, substantially to the effect that:

                  (a) The Insurer is a corporation validly existing, in good
            standing and licensed to transact the business of surety and
            financial guaranty insurance under the laws of the State of New
            York;

                  (b) The Insurer has the corporate power to execute and
            deliver, and to take all action required of it under the Guarantee,
            the Insurance Agreements and the MBIA Indemnification Agreement;

                  (c) Except as have already been obtained, no authorization,
            consent, approval, license, formal exemption or declaration from,
            nor any registration or filing with, any court or governmental
            agency or body of the United States of America or the State of New
            York, which if not obtained would affect or impair the validity or
            enforceability of the Guarantee, the Insurance Agreements or the
            MBIA Indemnification Agreement against the Insurer, is required in
            connection with the execution and delivery by the Insurer of the
            Guarantee, the Insurance Agreements or the MBIA Indemnification
            Agreement or in connection with the Insurer's performance of its
            obligations thereunder;

                  (d) The Guarantee, the Insurance Agreement and the MBIA
            Indemnification Agreement have been duly authorized, executed and
            delivered by the Insurer, and the Guarantee and, assuming due
            authorization, execution and delivery of the Insurance Agreements by
            the parties thereto (other than the Insurer), the Insurance
            Agreements constitute the legally valid and binding obligations of
            the Insurer, enforceable in accordance with their respective terms
            subject, as to enforcement, to (1) bankruptcy, reorganization,
            insolvency, moratorium and other similar laws relating to or
            affecting the enforcement of creditors' rights generally, including,
            without limitation, laws relating to fraudulent transfers or
            conveyances, preferential transfers and equitable subordination,
            presently or from time to time in effect and general principles of
            equity (regardless of whether such enforcement is considered in a
            proceeding in equity or at law), as such laws may be applied in any
            such proceeding with respect to the Insurer and (2) the
            qualification that the remedy of specific performance may be subject
            to equitable defenses and to the discretion of the court before
            which any proceedings with respect thereto may be brought; and

                  (e)   The Guarantee is not required to be registered
            under the Securities Act of 1933, as amended.

            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 the Insurer and public officials. References to
      the Prospectus in this paragraph (ix) include any supplements thereto.

      Company in this Agreement are true and correct on and as of the Closing

      are true and correct as of the dates specified in the Servicing Agreement,
      that no stop order suspending the effectiveness of the Registration
      Statement has been issued and no proceedings for that purpose have been
      instituted or are threatened by the Commission and that, subsequent to the
      date of the Prospectus, there has been no material adverse change in the
      financial position or results of operations of the Company's motor vehicle
      installment loan business except as set forth in or contemplated by the
      Prospectus or as described in such certificate.

            (xvii) The Underwriters shall have received a certificate, dated the
      Closing Date, of a Vice President or more senior officer of Onyx in which
      such officer shall state that,


                                       20
<PAGE>   21
      to the best of his or her knowledge after reasonable investigation, the

      reason to believe that the section of the Prospectus Supplement captioned
      "DESCRIPTION OF THE INSURER" or any such amendment thereof or supplement
      thereto as of its Effective Date or date of issuance, as the case may be,
      contained any untrue statement of a material fact or omitted to state any
      material fact required to be stated therein or necessary to make the
      statements therein, in light of the circumstances under which they were
      made, not misleading.

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

      8. Indemnification.

            (i) The Company will indemnify and hold harmless each Underwriter
      and each person, if any, who controls such Underwriter within the meaning
      of Section 15 of the Act against any losses, claims, damages or
      liabilities, joint or several, to which such Underwriter may become
      subject, under the Act or otherwise, insofar as such losses, claims,
      damages or liabilities (or actions in respect thereof) (a) arise out of,
      or are based upon, any untrue statement or alleged untrue statement of any
      material fact contained in the Registration Statement, or arise out of, or
      are based upon, the omission or alleged omission to state therein a
      material fact required to be stated therein or necessary to make the
      statements therein not misleading or (b) arise out of, or are based upon,
      any untrue statement or alleged untrue statement of any material fact
      contained in the Prospectus or arise out of, or are based upon, the
      omission or alleged omission to state therein a material fact necessary to
      make the statements therein, in light of the circumstances under which
      they were made, not misleading; and will reimburse each Underwriter for
      any legal or other expenses reasonably incurred, as incurred, by each
      Underwriter in connection with investigating or defending any such action
      or claim; provided, however, that the Company shall not be liable in any
      such case to the extent that any such loss, claim, damage or liability
      arises out of, or is based upon, an untrue statement or alleged untrue


                                       21
<PAGE>   22
      statement or omission or alleged omission (x) made in the Registration
      Statement or the Prospectus or any such amendment or supplement in
      reliance upon and in conformity with written information furnished to the
      Company by the Underwriters expressly for use therein, or (y) contained in
      any ABS Term Sheet to the extent set forth in subsection (ii) of this
      Section 8; provided, further, that the Company shall not be liable under
      this subsection (i) to the extent that such losses, claims, damages or
      liabilities arose out of or are based upon an untrue statement or omission
      made in any preliminary prospectus that is corrected in the final
      Prospectus (or any amendment or supplement thereto), and the Company has
      previously furnished copies thereof in sufficient quantity to the
      Underwriters, if the person asserting such loss, claim, damage or
      liability was not given the final Prospectus (or any amendment or
      supplement thereto) on or prior to the confirmation of the sale of the
      Notes.

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

            (iii) Each indemnified party shall give prompt notice to the
      indemnifying party of any action commenced against the indemnified party
      in respect of which indemnity may be sought hereunder, but failure to so
      notify an indemnifying party shall not relieve such indemnifying party
      from any liability which it may have hereunder or otherwise than on
      account of this indemnity agreement except and to the extent of any
      prejudice to such indemnifying party arising from such failure to provide
      such notice. In case any such action shall be brought against an
      indemnified party and it shall have notified the indemnifying party of the
      commencement thereof, the indemnifying party shall be entitled to
      participate therein and, to the extent that it shall wish, to assume the
      defense thereof, with counsel, satisfactory to such indemnified party (who
      shall not, except with the consent of the indemnified party, be counsel to
      the indemnifying party with respect to such action), and it being
      understood that the indemnifying party shall not, in connection


                                       22
<PAGE>   23
      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 Notes 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 Notes purchased by it hereunder. The
Company and each Underwriter agrees that it would not be just and equitable if
contribution pursuant to this Section 9 were determined by pro rata allocation
or by any other method of allocation which does not take account of the
equitable considerations referred to above in this Section 9. No person guilty
of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.

      10. Termination. The Underwriters may terminate this Agreement immediately
upon notice to the Company, if at any time, prior to the Closing Date, there has
occurred: (a) any change, or any development involving a prospective change, in
or affecting particularly the business or properties of the Company or Onyx
which, in the reasonable judgment of the Underwriters, materially impairs the
investment quality of the Notes; (b) any suspension or material limitation of
trading in securities generally on the New York Stock Exchange, or any


                                       23
<PAGE>   24
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; (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 Notes; or (e) there shall have occurred such a
material adverse change in general economic, political or financial conditions
(or the effect of international conditions on the financial markets of the
United States shall be such) as to make it, in the judgment of the Underwriters,
impractical or inadvisable to proceed with the public offering or delivery of
the Notes on the terms and in the manner contemplated in the Prospectus.

      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 Notes. If for any reason the purchase of the Notes 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 Notes 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 each Underwriter
for all out-of-pocket expenses (including fees and disbursements of counsel)
reasonably incurred by it in connection with the offering of the Notes.

      12. Notices. All communications hereunder will be in writing and, if sent
to the Representative, will be mailed, delivered or telegraphed and confirmed to

      13. Successors. This Agreement will inure to the benefit of, and be
binding upon, the parties hereto and their respective successors. Nothing
expressed or mentioned in this Agreement is intended or shall be construed to
give any person, firm or corporation, other than the parties hereto and their
respective successors and the controlling persons and officers and directors
referred to in Sections 8 and 9 and their heirs and legal representatives, any
legal or equitable right, remedy or claim under or in respect of this Agreement
or any provision herein contained. This Agreement and all conditions and
provisions hereof are intended to be for the sole and exclusive benefit of the
parties hereto and their respective successors, and said


                                       24
<PAGE>   25
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 Notes 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 Notes hereunder on the Closing Date and the aggregate
principal amount of the Notes that such defaulting Underwriter agreed but failed
to purchase does not exceed 10% of the total principal amount of the Notes, the
Representative may make arrangements satisfactory to the Representative and the
Company for the purchase of such Notes by other persons, including either of the
Underwriters, but if no such arrangements are made by the Closing Date, the
nondefaulting Underwriter(s) shall be obligated, in proportion to its respective
commitment hereunder, to purchase the Notes that such defaulting Underwriter
agreed but failed to purchase. If an Underwriter so defaults and the aggregate

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 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


                                      -9-
<PAGE>   15
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 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


                                      -10-
<PAGE>   16
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
payable on each Distribution Date as specified therein, subject to Section 3.01.
Interest accrued on any Note but not paid on any Distribution Date will be due
on the immediately succeeding Distribution Date, together with, to the extent
permitted by applicable law, interest on such shortfall at the related Interest
Rate. Interest on the Notes shall be calculated on the basis of a 360-day year
of twelve 30-day months, except for the Class A-1 Notes, which shall be
calculated on the basis of a 360-day year and the actual number of days in the
related Interest Accrual Period. Any installment of interest or principal, if
any, payable on any Note which is punctually paid or duly provided for by the
Issuer on the applicable Distribution Date shall be paid to the Person in whose
name such Note (or one or more Predecessor Notes) is registered on the Record
Date, by check mailed first-class, postage prepaid to such Person's address as
it appears on the Note Register on such Record Date, except that, unless
Definitive Notes have been issued pursuant to Section 2.11, with respect to
Notes registered on the Record Date in the name of the nominee of the Clearing
Agency (initially, such nominee to be Cede & Co.), payment will be made by wire
transfer in immediately available funds to the account designated by such
nominee and except for the final installment of principal payable with respect
to such Note on a Distribution Date, a Redemption Date or on the related Final
Scheduled Distribution Date, as the case may be (and except for the Redemption
Price for any Note called for redemption pursuant to Section 10.01), which shall
be payable as provided below. The funds represented by any such checks returned
undelivered shall be held in accordance with Section 3.03.

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

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

                        (ii) the Redemption Date;


                                      -11-
<PAGE>   17

                        (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 Holders representing not less than
                662/3% of the Outstanding Amount of the Highest Priority Class
                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 Notes shall be made pro rata to the
Noteholders of such Class entitled thereto. The Indenture Trustee shall notify
the Person in whose name a Note is registered at the close of business on the
Record Date preceding the Distribution Date on which the Issuer expects that the
final installment of principal, of and interest on, such Note will be paid. Such
notice shall be mailed within five Business Days of such Distribution Date (or,
in the case of Notes registered in the name of Cede & Co., as nominee of DTC,
such notice shall be provided within one Business Day of such Distribution Date)
or receipt of notice of termination of the Trust pursuant to Section 9.01(c) of
the Trust Agreement and shall specify that such final installment will be
payable only upon presentation and surrender of such Note and shall specify the
place where such Note may be presented and surrendered for payment of such
installment. Notices in connection with redemptions of Notes shall be mailed to
Noteholders as provided in Section 10.02. In addition, the Administrator shall
notify the Insurer and the Rating Agencies upon the final payment of interest
and principal of each Class of Notes, and upon the termination of the Trust, in
each case pursuant to the Administration Agreement.

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

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


                                      -12-
<PAGE>   18
                        (i) the provisions of this Section shall be in full
                force and effect;

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

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

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

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

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

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


                                      -13-
<PAGE>   19
Trustee shall be liable for any delay in delivery of such instructions and may
conclusively rely on, and shall be protected in relying on, such instructions.
Upon the issuance of Definitive Notes of a Class, the Indenture Trustee shall
recognize the Holders of the Definitive Notes as Noteholders hereunder.

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

               Section 2.12 Release of Collateral. Subject to Section 11.01 and
the terms of the Basic Documents, the Indenture Trustee shall release property
from the lien of this Indenture only upon receipt of an Issuer Request
accompanied by an Officer's Certificate, an Opinion of Counsel and Independent
Certificates in accordance with Sections 314(c) and 314(d)(l) of the TIA or an
Opinion of Counsel in lieu of such Independent Certificates to the effect that
the TIA does not require any such Independent Certificates.

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

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

                                   ARTICLE III

                                    COVENANTS

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


                                      -14-
<PAGE>   20
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 Note Distribution Account after required transfers thereto from the
other Trust Accounts shall be made on behalf of the Issuer by the Paying Agent
(including the Indenture Trustee when serving as a Paying Agent), and no amounts
so withdrawn from the Note Distribution Account for payments of Notes shall be
paid over to the Issuer except as provided in this Section.

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

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

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

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


                                      -15-
<PAGE>   21

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

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

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

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


                                      -16-
<PAGE>   22
the United States, in which case the Issuer will keep in full effect its
existence, rights and franchises under the laws of such other jurisdiction) and
will obtain and preserve its qualification to do business in each jurisdiction
in which such qualification is or shall be necessary to protect the validity and
enforceability of this Indenture, the Notes, and the Collateral.

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

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

                        (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


                                      -17-
<PAGE>   23
or referring to prior Opinions of Counsel in which such details are given, or
(ii) no such action shall be necessary to perfect such security interest.

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

               Section 3.07 Performance of Obligations; Servicing of Contracts.

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


                                      -18-
<PAGE>   24
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 or the Noteholders 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 in the
event that the Insurer is not entitled to appoint a successor servicer by
operation of Section 9.08 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 Residual Interest Instruments
evidencing not less than 51% of the Percentage Interests, shall appoint a
Successor Servicer. The Successor Servicer shall succeed to all the
responsibilities, duties and liabilities of the Servicer under the Sale and
Servicing Agreement. Notwithstanding the foregoing, if the Notes have not been
paid in full, the Indenture Trustee may, if it shall be unwilling to act, or
shall, if it shall be legally unable to so act, appoint, or petition a court of
competent jurisdiction (with any related costs to be at the sole expense of the
Issuer) to appoint, any established financial institution, having a net worth of
not less than $50,000,000 and whose regular business shall include the servicing
of automotive retail installment sales contracts, as the successor to the
Servicer under the Sale and Servicing Agreement. If the Indenture Trustee shall
succeed to the Servicer's duties as servicer of the Contracts as provided
herein, it shall do so in its individual capacity and not in its capacity as
Indenture Trustee and, accordingly, the provisions of Article Six shall be
inapplicable to the Indenture Trustee in its duties as the successor to the
Servicer and the servicing of the 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;


                                      -19-
<PAGE>   25
                        (ii) claim any credit on, or make any deduction from the
                principal or interest payable in respect of, the Notes (other
                than amounts properly withheld from such payments under the Code
                or applicable state law) or assert any claim against any present
                or former Noteholder by reason of the payment of the taxes
                levied or assessed upon any part of the Collateral;

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

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

               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, 2000), 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


                                      -20-

                consolidation or merger will not have any material adverse tax
                consequence to the Trust, the Insurer or any Noteholder;

                        (v) any action as is necessary to maintain the lien and
                security interest created by this Indenture shall have been
                taken;

                        (vi) the Issuer shall have delivered to the Indenture

               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


                                      -25-

Policy;

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

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

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

Indenture Trustee or the Insurer, or to the Issuer and the Indenture Trustee by
the Holders of at least 25% of the Outstanding Amount of the Notes acting
together as a single Class;

               (e) the filing of a decree or order for relief by a court having
jurisdiction in the premises in respect of the Issuer or any substantial part of
the Collateral in an involuntary case under any applicable federal or state
bankruptcy, insolvency or other similar law now or hereafter in effect, or
appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator or
similar official of the Issuer or for any substantial part of the Collateral, or

to pay its debts as such debts become due, or the taking of action by the Issuer
in furtherance of any of the foregoing;

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

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

               Section 5.02 Rights Upon Event of Default.

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

               (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 Holders representing at least
662/3% 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 the unpaid principal
amount of the Notes, together with accrued and unpaid interest thereon, shall
become immediately due and payable.

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

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

               (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 Holders representing at
least 662/3% 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

any covenant or agreement in this Indenture or in aid of the exercise of any
power granted herein, or to enforce any other proper remedy or legal or
equitable right vested in the Indenture Trustee by this Indenture or by law.

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

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

                        (ii) unless prohibited by applicable law and

                election of a trustee, a standby trustee or Person performing
                similar functions in any such Proceedings;

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

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

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


                                      -28-

Indenture Trustee and each predecessor Indenture Trustee except as a result of
negligence or bad faith.

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

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

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

                available to cover losses to Noteholders 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


                                      -30-
<PAGE>   36
pursuant to Section 5.04(a)(iv) above, the Indenture Trustee shall, prior to any
such public or private sales, notify all Residual Interestholders of the
proposed sale. The Indenture Trustee shall provide the Residual Interestholders
the right to match the highest liquidation price offered at any such sale.

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

               Section 5.06 Priorities.

               (a) If the Notes have been declared to be due and payable under
Section 5.02 following an Indenture Event of Default and such declaration and
its consequences have not been rescinded and annulled, any money collected by
the Indenture Trustee with respect to the Collateral or the Notes 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 or the Notes
(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 B Notes, to pay accrued
                interest on the Class B Notes (including, to the extent
                permitted by applicable law, interest accrued on any interest
                accrued but not timely paid) on the Class B Notes at the Class B
                Rate;

                        fifth, 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 such Class of Notes is reduced to
                zero;

                        sixth, to the holders of Class B Notes, to pay principal
                on the Class B Notes, until the Outstanding Amount of the Class
                B Notes is reduced to zero;

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


                                      -31-
<PAGE>   37
                        eighth, any excess amounts remaining after making the
                distributions described in clauses first through seventh to the
                Spread Account, to be applied in accordance with the Insurance
                Agreement.

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

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

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

                        (ii) the Holders of not less than 25% of the Outstanding
                Amount of the 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; and

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

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

        In the event the Indenture Trustee shall receive conflicting or
inconsistent requests and indemnity from two or more groups of Holders of Notes,
each representing less than a majority of the Outstanding Amount of the Notes,
the Indenture Trustee shall act at the request of the Holders of the Notes with
the greater Outstanding Amount of Notes; provided, however that if such groups
of Holders of Notes have the same Outstanding Amount of Notes, the Indenture
Trustee in its sole discretion may determine what action, if any, shall be
taken, notwithstanding any other provisions of this Indenture and any such
action shall be binding on all parties.


                                      -32-

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

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

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

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

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

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

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

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


                                      -33-
<PAGE>   39
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
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 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


                                      -34-
<PAGE>   40
application of any other relief under or with respect to this Indenture. Neither
the lien of this Indenture nor any rights or remedies of the Indenture Trustee
or the Noteholders shall be impaired by the recovery of any judgment by the
Indenture Trustee against the Issuer or by the levy of any execution under such
judgment upon any portion of the Collateral or upon any of the assets of the
Issuer. Any money or property collected by the Indenture Trustee shall be
applied in accordance with Section 5.06.

               Section 5.17 Performance and Enforcement of Certain Obligations.

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

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

                                   ARTICLE VI

                              THE INDENTURE TRUSTEE

               Section 6.01 Duties of Indenture Trustee.

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


                                      -35-
<PAGE>   41
               (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.

               (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.

<PAGE>   42
               (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 Highest Priority Class or a majority of the Outstanding Amount
of Notes, as applicable, relating to the time, method and place of conducting
any proceeding for any remedy available to the Indenture Trustee, or exercising
or omitting to exercise any trust or power conferred upon the Indenture Trustee,
under this Indenture.

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

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

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

               Section 6.02 Rights of Indenture Trustee.

               (a) Except as otherwise provided in the second succeeding
sentence, the Indenture Trustee may conclusively rely and shall be protected in
acting upon or refraining from acting upon any resolution, certificate,
statement, instrument, opinion, report, notice, request, consent, order, note,
direction, demand, election or other paper or document believed by it to be
genuine and to have been signed or presented by the proper person. The Indenture
Trustee need not investigate any fact or matter stated in the document.
Notwithstanding the foregoing, the Indenture Trustee, subject to Section
6.01(b)(ii) upon receipt of all resolutions, certificates, statements, opinions,
reports, documents, orders or other instruments furnished to the Indenture
Trustee that shall be specifically required to be furnished pursuant to any
provision of this Indenture, shall examine them to determine whether they comply
as to form to the requirements of this Indenture.

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

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

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

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

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

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

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

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

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

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

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

               Section 6.07 Compensation and Indemnity. The Issuer shall cause
the Servicer to pay to the Indenture Trustee from time to time reasonable
compensation for its services. The Indenture Trustee's compensation shall not be
limited by any law on compensation of a trustee of an express trust. The Issuer
shall cause the Servicer to reimburse the Indenture Trustee for all reasonable
out-of-pocket expenses incurred or made by it, including costs of collection, in
addition to the compensation for its services. Such expenses shall include the
reasonable compensation and expenses and disbursements and advances of the
Indenture Trustee's agents,


                                      -39-
<PAGE>   45
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 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


                                      -40-
<PAGE>   46
                        (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 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


                                      -41-
<PAGE>   47
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

                        (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


                                      -42-
<PAGE>   48
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.

the Issuer of any such request, a list of similar form and content as of a date

however, that so long as the Indenture Trustee is the Note Registrar, no such

Indenture Trustee is not the Note Registrar, the Issuer shall furnish to the
Insurer in writing at such times as the Insurer may reasonably request a copy of
the list.

               Section 7.02 Preservation of Information; Communications to
Noteholders.

               (a) The Indenture Trustee shall preserve, in as current a form as

               Section 8.01 Collection of Money.

               (a) General. Except as otherwise expressly provided herein, the
Indenture Trustee may demand payment or delivery of, and shall receive and
collect, directly and without intervention or assistance of any fiscal agent or
other intermediary, all money and other property payable to or receivable by the
Indenture Trustee pursuant to this Indenture. The Indenture Trustee shall apply
all such money received by it as provided in this Indenture. Except as otherwise
expressly provided in this Indenture, if any default occurs in the making of any
payment or performance under any agreement or instrument that is part of the
Collateral, the Indenture Trustee may take such action as may be appropriate to
enforce such payment or performance, including the institution and prosecution
of appropriate Proceedings. Any such action shall be without prejudice to any
right to claim a Default or Event of Default under this Indenture and any right
to proceed thereafter as provided in Article Five.

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

Collections available with respect to such


                                      -45-

               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.

               Section 9.02 Supplemental Indentures With Consent of Noteholders.
The Issuer and the Indenture Trustee, when authorized by an Issuer Order, also

Indenture for any and all purposes.

               Section 9.05 Conformity With Trust Indenture Act. Every amendment

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

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

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


                                      -53-
<PAGE>   59
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.

               (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.

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 2000-B, in care of
                Bankers Trust (Delaware), as Owner Trustee, 1011 Centre Road,
                Suite 200, Wilmington, Delaware 19805-1266, Attention: Corporate
                Trust Administration Department, or at any other address
                furnished in writing to the Indenture Trustee by the Issuer; or

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

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

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

        Where this Indenture provides for notice in any manner, such notice may
be waived in writing by any Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Noteholders shall be filed


                                      -55-
<PAGE>   61
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,


                                      -56-
<PAGE>   62
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,
directly or indirectly, with respect to the obligations of the Issuer, the Owner
Trustee or the Indenture Trustee on the Notes or under this Indenture or any
certificate or other writing delivered in connection herewith or therewith,
against (i) the Indenture Trustee or the Owner Trustee in its individual
capacity, (ii) any owner of a beneficial interest in the Issuer or (iii) any
partner, owner, beneficiary, agent, officer, director, employee or agent of the
Indenture Trustee or the Owner Trustee in its individual capacity, any Holder of
a beneficial interest in the Issuer, the Owner Trustee or the Indenture Trustee
or of any successor or assign of the Indenture Trustee or the Owner Trustee in
its individual capacity, except as any such Person may have expressly agreed (it
being understood that the Indenture Trustee and the Owner Trustee have no such
obligations in their individual capacity) and except that any such partner,
owner or beneficiary shall be fully liable, to the extent provided by applicable
law, for any unpaid consideration for stock, unpaid capital contribution or
failure to pay any installment or call owing to such entity. For all purposes of
this Indenture, in the performance of any duties or obligations of the Issuer
hereunder, the Owner Trustee shall be subject to, and entitled to the benefits
of, the terms and provisions of Articles Six, Seven and Eight of the Trust
Agreement.

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

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

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

               Section 11.20 Certain Matters Regarding the Insurer. So long as
an Insurer Default shall not have occurred and be continuing, the Insurer shall
have the right to exercise all rights, including voting rights, which the
Noteholders or Residual Interestholders are entitled to exercise pursuant to
this Indenture, without any consent of such Noteholders or Residual
Interestholders; provided, however, that without the consent of each Noteholder
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 or Residual Interest
Instrument, (ii) adversely affect in any material respect the interests of the
Holders of any Notes 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


                                      -58-
<PAGE>   64
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 or the Residual Interest Instruments; provided, that the consent of
the Insurer shall be required at all times with respect to any amendment of this
Indenture.


                                      -59-

        IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be

title to all the Trust Estate shall be vested at all times in the Trust as a

The Owners shall be entitled to receive distributions with respect to their
undivided ownership interest therein only in accordance with Articles Five and
Nine. No transfer, by operation of law or otherwise, of any right, title or
interest of the Owners to and in their ownership interest in the Trust Estate

transferee to an accounting or to the transfer to it of legal title to any part
of the Trust Estate.

        Section 2.08 Situs of Trust. The Trust will be located and administered
in the State of Delaware or the State of New York. All bank accounts maintained
on behalf of the Trust shall be located in the State of California, the State of

or prohibit the Owner Trustee from having employees within or without the State
of Delaware. Payments will be received by the Trust only in California, Delaware
or New York and payments will be made by the Trust only from California,
Delaware or New York. The only office of the Trust will be at the Owner Trustee

        properties.

               (v) There are no proceedings or investigations pending, or to the

            RESIDUAL INTEREST INSTRUMENTS AND TRANSFER OF INTERESTS

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

        Section 3.02 The Residual Interest Instruments and the Notes.

        (a) The Residual Interest Instruments shall not be issued with a
principal amount. The Residual Interest Instruments shall be executed by the
Owner Trustee on behalf of the Trust by manual or facsimile signature of an
authorized officer of the Owner Trustee, and authenticated by the Trust Agent by
the manual or facsimile signature of an authorized officer of the Trust Agent
and shall be deemed to have been validly issued when so executed and
authenticated. Residual Interest Instruments bearing the manual or facsimile
signatures of individuals who were, at the time when such signatures were
affixed, authorized to sign on behalf of the Owner Trustee or the Trust Agent
shall be validly issued by the Trust, notwithstanding that such individuals or
any of them have ceased to be so authorized prior to the execution,
authentication and delivery of such Residual Interest Instruments or did not
hold such offices at the date of such Residual Interest Instruments. All
Residual Interest Instruments shall be dated the date of their authentication.

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

        Section 3.03 Execution, Authentication and Delivery of Residual Interest
Instruments and Notes. The Owner Trustee shall cause to be executed,
authenticated and delivered upon the order of the Depositor, in exchange for the
Contracts and the other assets of the Trust, simultaneously with the sale,
assignment and transfer to the Trust of the Contracts, and such other assets,
(a) the Residual Interest Instruments representing 100% of the Percentage
Interests of the Residual Interest, evidencing the entire ownership of the
Trust, and (b) Notes executed by the Trust in aggregate principal amount of, in
the case of the (i) Class A-1 Notes, $77,800,000, (ii) Class A-2 Notes,
$120,000,000, (iii) Class A-3 Notes, $131,000,000, (iv) Class A-4 Notes,
$94,200,000, and (v) Class B Notes, $27,000,000. The Trust Agent is hereby
authorized to direct, on behalf of the Trust, the Indenture Trustee to
authenticate and deliver the Notes upon the order of the Depositor. No Residual
Interest Instrument shall entitle its Owner to any benefit under this Agreement,
or be valid for any purpose, unless there appears on such Residual Interest
Instrument a certificate of authentication substantially in the form set forth
in the form of Residual Interest Instrument attached hereto as Exhibit B,
executed by the Trust Agent or another authenticating agent of the Owner
Trustee, by manual or facsimile signature, and such certificate upon any
Residual Interest Instrument shall be conclusive evidence, and the only
evidence, that


                                      -8-
<PAGE>   13
such Residual Interest Instrument has been duly authenticated and delivered
hereunder. Upon issuance, authorization and delivery pursuant to the terms
hereof, the Residual Interest Instruments will be entitled to the benefits of
this Agreement.

        Section 3.04 Registration of Transfer and Exchange of Residual Interest
Instruments.

        (a) The Certificate Registrar shall keep or cause to be kept, a
Certificate Register, subject to such reasonable regulations as it may
prescribe. The Certificate Register shall provide for the registration of
Residual Interest Instruments and transfers and exchanges of Residual Interest
Instruments as provided herein. The Trust Agent, as agent for the Trust, is
hereby initially appointed Certificate Registrar for the purpose of registering
Residual Interest Instruments and transfers and exchanges of Residual Interest
Instruments as herein provided. In the event that, subsequent to the Closing
Date, the Trust Agent notifies the Administrator that the Trust Agent is unable
to act as Certificate Registrar, the Administrator 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 Residual Interest
Instrument 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 Residual Interest
Instruments in authorized denominations of a like aggregate principal amount.

        (c) At the option of a Owner of a Residual Interest Instrument, Residual
Interest Instruments may be exchanged for other Residual Interest Instruments in
authorized denominations of a like Percentage Interest, upon surrender of the
Residual Interest Instruments to be exchanged at the office of the Certificate
Registrar. Whenever any Residual Interest Instruments 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 Residual Interest Instruments that the Owner
making the exchange is entitled to receive. Every Residual Interest Instrument
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 Owner 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 3.11(a) and (b).

        (d) No service charge shall be made for any registration of transfer or
exchange of Residual Interest Instruments, 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 Residual Interest Instruments.

        (e) All Residual Interest Instruments surrendered for registration of
transfer or exchange, if surrendered to any agent of the Owner Trustee under
this Agreement, shall be delivered to the Trust Agent and promptly canceled by
it, or, if surrendered to the Trust Agent, shall be promptly canceled by it, and
no Residual Interest Instruments shall be issued in lieu


                                      -9-
<PAGE>   14
thereof except as expressly permitted by any of the provisions of this
Agreement. The Trust Agent shall dispose of canceled Residual Interest
Instruments in accordance with the normal industry practice.

        Section 3.05 Mutilated, Destroyed, Lost or Stolen Residual Interest
Instruments. If (a) any mutilated Residual Interest Instrument is surrendered to
the Certificate Registrar, or the Certificate Registrar receives evidence to its
satisfaction of the destruction, loss or theft of any Residual Interest
Instrument, 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 Residual Interest
Instrument 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 Residual Interest Instrument, a new
Residual Interest Instrument of like tenor and fractional undivided interest. In
connection with the issuance of any new Residual Interest Instrument under this
Section, the Owner Trustee or, on its behalf, the Trust Agent, may require the
payment by the Owner of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto. Any duplicate Residual Interest
Instrument 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 Residual Interest Instrument shall
be found at any time.

        Section 3.06 Persons Deemed Owners. Prior to due presentation of a
Residual Interest Instrument 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 Residual Interest
Instrument is registered as the owner of such Residual Interest Instrument for
the purpose of receiving distributions pursuant to Section 5.01 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. Each
Owner, by receiving and holding a Residual Interest Instrument, 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 Residual Interest Instruments may be surrendered for registration of
transfer or exchange and where notices and demands to or upon the Trust Agent in
respect of the Residual Interest Instruments 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,


                                      -10-
<PAGE>   15
the Servicer and to the Owners of any change in the location of the Certificate
Register or any such office or agency.

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

        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 Owners pursuant to
Section 5.01 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 Payment 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 Owners in trust for the benefit of the Owners entitled
thereto until such sums shall be paid to the Owners. 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.

                   APPLICATION OF TRUST FUNDS; CERTAIN DUTIES

        Section 5.01 Application of Trust Funds.

        (a) On each Distribution Date, the Trust Agent, on behalf of the Owner
Trustee, shall direct the Paying Agent to distribute to the Owners from amounts
on deposit in the Payment Account the distributions as provided in Section
4.04(b) of the Sale and Servicing Agreement with respect to such Distribution
Date.

        (b) On each Distribution Date, the Trust Agent, on behalf of the Owner
Trustee, shall cause the Paying Agent to send to each Owner the statement or
statements provided to the Owner Trustee or the Trust Agent by the Servicer
pursuant to Section 4.05 of the Sale and Servicing Agreement with respect to
such Distribution Date.

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

transfer of immediately available funds or pursuant to other arrangements), the
amount to be distributed to such Owner pursuant to such Owner's Residual
Interest Instruments.

        Section 5.03 No Segregation of Monies; No Interest. Subject to Section
5.01, 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 5.04 Accounting and Reports to the Noteholders, Owners, the
Internal Revenue Service and Others. The Trust Agent shall (a) maintain (or
cause to be maintained) the books of the Trust on a calendar year basis and the
accrual method of accounting, (b) deliver to each Owner, as may be required by
the Code and applicable Treasury Regulations, such information as may be
required (including Schedule K-1) to enable each Owner to prepare its federal
and state income tax returns, (c) file such tax returns relating to the Trust

elections as from time to time may be required or appropriate under any
applicable state or federal statute or any rule or regulation thereunder so as
to maintain the Trust's characterization as a partnership for federal income tax
purposes, (d) cause such tax returns to be signed in the manner required by law
and (e) collect or cause to be collected any withholding tax as described in and

Depositor holds a Residual Interest Instrument, and otherwise the holder of the
largest Percentage Interest in the Residual Interest Instruments shall sign such
documents.

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

        Section 6.01 General Authority. Subject to the provisions and
limitations of Sections 2.03 and 2.06, the Owner Trustee is authorized and
directed to execute and deliver on behalf of the Trust the Basic Documents to
which the Trust is to be a party and each certificate or other document attached
as an exhibit to or contemplated by the Basic Documents to which the Trust is to
be a party and any amendment or other agreement, as evidenced conclusively by
the Owner Trustee's execution thereof. In addition to the foregoing, the Owner
Trustee is authorized, but shall not be obligated, to take all actions required
of the Trust pursuant to the Basic Documents. The Owner Trustee is further
authorized from time to time to take such action as the Administrator recommends
with respect to the Basic Documents.

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

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

        (b) it shall be the duty of the Trust Agent to discharge all of its
responsibilities pursuant to the terms of this Agreement and the other Basic
Documents to which the Trust and the Trust Agent are a party and to administer
the Trust in the interest of the Owners, subject to the Basic Documents and in
accordance with the provisions of this Agreement.

        Section 6.03 Action Upon Instruction.

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

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


                                      -17-
<PAGE>   22
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 from 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.

        Section 6.04 No Duties Except as Specified in this Agreement or in
Instructions. Neither the Owner Trustee nor the Trust Agent shall have any duty
or obligation to manage, make any payment with respect to, register, record,
sell, dispose of or otherwise deal with the Trust Estate, or to otherwise take
or refrain from taking any action under, or in connection with, any document
contemplated hereby to which the Owner Trustee or the Trust Agent, as
applicable, is a party, except as expressly provided by the terms of this
Agreement or in any document or written instruction received by the Owner
Trustee or the Trust Agent, as applicable, pursuant to Section 6.03; and no
implied duties or obligations shall be read into this Agreement or any other
Basic Document against the Owner Trustee or the Trust Agent. Neither the Owner
Trustee nor the Trust Agent shall have any responsibility for filing any
financing or continuation statement in any public office at any time or to
otherwise perfect or maintain the perfection of any security interest or lien
granted to it hereunder or to prepare or file with the Commission any filing for
the Trust or to record this Agreement or any other Basic Document. Each of the
Owner


                                      -18-

Trustee and the Trust Agent nevertheless agrees that it will, at its own cost
and expense, promptly take all action as may be necessary to discharge any liens
on any part of the Trust Estate that result from actions by, or claims against,
the Owner Trustee or the Trust Agent, as applicable, that are not related to the
ownership or the administration of the Trust Estate or the Grant of any portion
thereof to the Indenture Trustee pursuant to the Indenture.

        Section 6.05 No Action Except Under Specified Documents or Instructions.
Neither the Owner Trustee nor the Trust Agent shall manage, control, use, sell,
dispose of or otherwise deal with any part of the Trust Estate except in
accordance with (i) the powers granted to and the authority conferred upon the

(ii) the other Basic Documents and (iii) any document or instruction delivered
to the Owner Trustee or the Trust Agent, as applicable, pursuant to Section
6.03.

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

                         TERMINATION OF TRUST AGREEMENT

        Section 9.01 Termination of Trust Agreement.

        (a) This Agreement (other than Article Eight) and the Trust shall
terminate and be of no further force or effect upon the earlier of (i) final
distribution of all monies or other property or proceeds of the Trust Estate in
accordance with the terms of the Indenture, the Sale and Servicing Agreement and
Article Five and (ii) the expiration of 21 years from the death of the survivor
of the descendants of Joseph P. Kennedy, the late Ambassador of the United
States to the Court of St. James's, living on the date hereof. The bankruptcy,
liquidation, dissolution, death or incapacity of any Owner shall not (i) operate
to terminate this Agreement or the Trust, (ii) entitle such Owner's legal
representatives or heirs to claim an accounting or to take any action or
proceeding in any court for a partition or winding up of all or any part of the
Trust or Trust Estate or (iii) otherwise affect the rights, obligations and
liabilities of the parties hereto.

        (b) Except as provided in Section 9.01(a), neither the Depositor, the
Insurer nor any Owner shall be entitled to revoke or terminate the Trust.

        (c) Notice of any termination of the Trust, specifying the Distribution
Date upon which Owners shall surrender their Residual Interest Instruments to
the Paying Agent for payment of the final distribution and cancellation, shall
be given by the Trust Agent by letter to Owners 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 distribution in respect of
the Residual Interest Instruments shall be made upon presentation and surrender
of the Residual Interest Instruments 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
Residual Interest Instruments 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 Owners. Upon presentation and
surrender of the Residual Interest Instruments, the Paying Agent shall cause to
be distributed to Owners on a pro rata basis any amounts remaining in the Trust
upon the termination of this Agreement. In addition, the Trust Agent shall
notify the Rating Agencies upon the final distribution in respect of the
Residual Interest Instruments.

        (d) In the event that all of the Owners shall not surrender their
Residual Interest Instruments 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 Owners to surrender their Residual
Interest Instruments for cancellation and receive the final distribution with
respect thereto. If within one year after the second notice all the Owners 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 Owners concerning surrender of their Residual Interest Instruments,
and the cost thereof shall be paid out of the funds and other assets that shall
remain subject to this Agreement.

       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.

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


                                      -26-
<PAGE>   31
instrument shall be delivered to the outgoing Owner Trustee so removed and one
copy to the successor Owner Trustee, and shall pay all fees owed to the outgoing
Owner Trustee.

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

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

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

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

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

        Section 10.05 Appointment of Co-Trustee or Separate Trustee.
Notwithstanding any other provisions of this Agreement, at any time, for the
purpose of meeting any legal requirements of any jurisdiction in which any part
of the Trust Estate or any Financed Vehicle may at the time be located, the
Administrator and the Owner Trustee acting jointly shall have the power and
shall execute and deliver all instruments to appoint one or more Persons
approved by


                                      -27-
<PAGE>   32
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 to do so, the Owner Trustee and the Insurer shall
have the power to make such appointment. No co- trustee or separate trustee
under this Agreement shall be required to meet the terms of eligibility as a
successor Owner Trustee, provided that such co-trustee or successor trustee must
be acceptable to the Rating Agencies and no notice of the appointment of any
co-trustee or separate trustee shall be required pursuant to Section 10.03.

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

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

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

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

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

        Any separate trustee or co-trustee may at any time appoint the Owner
Trustee as its agent or attorney-in-fact with full power and authority, to the
extent not prohibited by law, to do any lawful act under or in respect of this
Agreement on its behalf and in its name. If any separate trustee or co-trustee
shall die, become incapable of acting, resign or be removed, all of its estates,
properties, rights, remedies and trusts shall vest in and be exercised by the
Owner Trustee, to the


                                      -28-
<PAGE>   33
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 making the distributions from
the Payment Account 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 and 5.01 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.

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 Owner; (ii)
any such action shall be deemed not to materially and adversely affect the

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 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 Owner if the Person requesting such amendment obtains an opinion of counsel

pursuant to any other provision of this Agreement shall be conclusive and
binding on such Holder and on all future Holders of such Note 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 Owners, with the consent of Owners
evidencing not less than 51% of the Percentage Interests, for the purpose of

Trustee shall furnish written notification of the substance of such amendment or
consent, together with a copy thereof, to the Indenture Trustee, the Insurer,
the Administrator and each Rating Agency.

        (d) Promptly after the execution of any such amendment or consent, the
Trust Agent shall furnish written notification of the substance of such
amendment or consent to each Owner. It shall not be necessary for the consent of
Owners, 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

by the Basic Documents and that all conditions precedent in the Basic Documents
for the execution and delivery thereof by the Trust, the Owner Trustee or the
Trust Agent, as the case may be, have been satisfied. The Owner Trustee and the
Trust Agent may, but shall not be obligated to, enter into any such amendment
that affects the Owner Trustee's or the Trust Agent's own rights, duties or
immunities under this Agreement or otherwise.

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.

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.

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

        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 Noteholders and the
Insurer, a first priority perfected security interest in all of the Seller's
right, title and interest in the Trust Property whether now existing or
hereafter created and all proceeds of the foregoing to secure the loan deemed to
be made in connection with such pledge and, in such event, this Agreement shall
constitute a security agreement under applicable law.

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

                (i)     the Seller shall have delivered to the Custodian, on

                        Trustee and the Insurer, on the Business Day immediately
                        preceding the related Prefunding Transfer Date, a duly
                        executed Transfer Certificate, substantially in the form
                        of Exhibit C- 1;

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

                (iii)   the Seller shall certify to the Indenture Trustee and
                        the Insurer that the addition of such Prefunded

                        consequence to the Issuer or the Noteholders;

                (iv)    the Funding Period shall not have terminated;

                        adverse to the interests of the Noteholders or the
                        Insurer shall have been utilized in selecting the

                        modification or withdrawal of its then current rating of
                        the Notes without regard to the Policy;

                (vii)   the weighted average APR (using the Recomputed Yield for
                        the Rule of 78's Contracts) of the Contracts (after

                        Contracts) shall not be less than 15.00%;

                (viii)  less than 20% of the Prefunded Contracts transferred by
                        the Seller to the Issuer since the Closing Date,
                        including all Prefunded Contracts being transferred on
                        such Prefunding Transfer Date, shall have an original

                        shall not be greater than 59 months;

                        aggregate Outstanding Principal Balance, as of the
                        related Prefunding Cut-Off Date, of the Prefunded
                        Contracts to be conveyed by the Seller to the Issuer on
                        such Prefunding Transfer Date shall equal or exceed
                        $10,000,000 and the Insurer shall have consented to such
                        transfer;

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

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

outstanding security interests in the Contracts.

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

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

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

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

        (j) On the Prefunding Closing Date, the Seller shall:

                                      -24-

                (i)     deliver a certificate from each secured creditor of the
                        Seller confirming that such creditor has no claim of any
                        security interest in any of the Prefunded Contracts
                        transferred during the Funding Period;

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

                (iii)   deliver to each Rating Agency, the Insurer and the
                        Indenture Trustee an Opinion of Counsel with respect to
                        the absence of negative tax consequences to the Trust,
                        the characterization of the transfer of the Prefunded
                        Contracts and the perfection of the Indenture Trustee's
                        interest on behalf of the Noteholders;

                (iv)    deliver to each Rating Agency, the Insurer and the
                        Indenture Trustee with respect to any state (other than
                        California) in which 10% or more of the Contracts
                        (including the Prefunded Contracts), by Outstanding
                        Principal Balance, were originated, an opinion with
                        respect to the perfection of the security interest of
                        the Indenture Trustee in the Financed Vehicles securing
                        the Contracts originated in such state; and

                (v)     deliver to the Insurer an Opinion of Counsel to the
                        effect that Onyx is duly qualified as a foreign
                        corporation to do business, and is in good standing, in
                        each of the states in which Prefunded Contracts have
                        been originated.

        Failure to comply with any of the conditions set forth in this Section
2.01(j) on the Prefunding Closing Date shall be deemed to be a breach of a
representation and warranty with respect to each of the Prefunded Contracts to
which such failed conditions relate as of the Prefunding Closing Date.

                        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 named as
                        the original secured party under the related Contract,
                        and in either case, the Indenture Trustee on behalf of
                        the Noteholders 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.

                (iv)    As of the Closing Date, the Seller had good and
                        marketable title to and was the sole owner of each such

                        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 related Cut-Off Date, the most recent

                        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

                        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

                        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

                        there does not exist any continuing condition that with

                        such secured party were still the owner of the Contract)
                        against all parties claiming an interest in such

                        operation of the terms of such Contract or the exercise

                        is secured by a Financed Vehicle that has not been
                        repossessed without reinstatement.

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

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

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

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

        SECTION 2.03. REPURCHASE OF CERTAIN CONTRACTS.

        The representations and warranties of the Seller set forth in Section
2.02 with respect to each Contract and each of the conditions set forth in
Section 2.01(c) with respect to each transfer of Prefunded Contracts and Section
2.01(j) with respect to the Prefunding Closing Date and sale of Prefunded
Contracts shall survive delivery of the Contract Documents and shall continue
until the termination of this Agreement. Upon discovery by the Seller, the
Servicer, the Insurer or a Responsible Officer of the Owner Trustee, the
Indenture Trustee or the Trust Agent that any of such representations and
warranties was incorrect or that any of such conditions was unsatisfied as of
the time made or that any of the Contract Documents relating to any such
Contract has not been properly executed by the Obligor or contains a material
defect or has not been received by the Custodian, such Person making such
discovery shall give prompt notice to the other such Persons. If any such
defect, incorrectness or omission materially and adversely affects the interest
of the Noteholders, the 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
Noteholders 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 Noteholders 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


                                      -36-
<PAGE>   41
                        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.

                (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).


                                      -37-
<PAGE>   42
        For so long as the Servicer is the Custodian of the Contract Documents,
the Servicer need not maintain the Contract Documents held by it in a file area
physically separate from the other installment sales contracts or loans owned or
serviced by it or any of its Affiliates, unless the Insurer requires such
segregation.

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

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

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

        (d) Monthly Reports. On the Servicer Report Date of each month,
commencing with the month next succeeding the month of the Closing Date, the
Servicer shall deliver to the Issuer, the Indenture Trustee and the Insurer a
certificate of a Servicing Officer stating (i) the Contract Number and
outstanding principal balance of each Contract that has become a Liquidated
Contract since the Business Day immediately preceding the date of the last
certificate delivered pursuant to this subsection (or since the Closing Date in
the case of the first such certificate); (ii) that, if such Contract has been
the


                                      -38-
<PAGE>   43
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; (iii) that, if such Contract has been the subject
of a Full Prepayment pursuant to clause (b) of the definition of the term "Full
Prepayment," the correct Purchase Amount has been deposited in or credited to
the Collection Account in accordance with Section 2.03, 3.07 or 4.02; (iv) that,
if such Contract is a Liquidated Contract pursuant to clause (ii) of the
definition of the term "Liquidated Contract," there have been deposited in or
credited to the Collection Account the related Net Liquidation Proceeds in
accordance with Section 4.02; and (v) that the Indenture Trustee is authorized
to release such Contract and the related Contract Documents as provided herein.

        (e) Schedule of Title Documents. The Servicer shall deliver to the
Indenture Trustee, the Issuer and the Insurer (i) within 60 days of the Closing
Date with respect to the Funded Contracts and within 60 days of the Prefunding
Closing Date with respect to the Prefunded Contracts, a schedule of Title
Documents for Financed Vehicles which, as of the Closing Date or the Prefunding
Closing Date, as applicable, did not show Onyx as first lienholder and (ii)
within 180 days of the Closing Date with respect to the Funded Contracts and
within 180 days of the Prefunding Closing Date with respect to the Prefunded
Contracts, a schedule of Title Documents for Financed Vehicles which, as of the
date prior to such delivery, do not show Onyx 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 Noteholders 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 Noteholders 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 Noteholders, the Custodian, the Indenture Trustee, the Trust Agent and the
Insurer against any taxes that may be asserted at any time


                                      -39-
<PAGE>   44
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
Noteholders 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 Class B Final
Scheduled Distribution Date. If Onyx shall subsequently resign as Servicer in
accordance with the terms of this Agreement or if all of the rights and
obligations of the Servicer shall have been terminated pursuant to Section 7.01,
the appointment of the Servicer as Custodian may be terminated by the Insurer,
or if an Insurer Default has occurred and is continuing, by Holders evidencing
not less than 25% of the outstanding principal amount of the Highest Priority
Class, or by the Indenture Trustee. 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 Notes
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.

<PAGE>   45
        SECTION 2.10. COLLECTING TITLE DOCUMENTS NOT DELIVERED AT THE CLOSING
                      DATE.

        In the case of any Funded Contract or Prefunded Contract in respect of
which, in place of a Title Document, the Custodian received on the Closing Date
or the Prefunding Closing Date, as applicable, written evidence from the Dealer
selling the related Financed Vehicle that, or otherwise in respect of which, the
Title Document for such Financed Vehicle showing Onyx 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 as first lienholder is
not received by the Servicer (or in the case of the State of California,
verified by the Servicer in the electronic title records) within 180 days after
the Closing Date with respect to the Funded Contracts or within 180 days after
the Prefunding Closing Date with respect to the Prefunded Contracts, then the
representation and warranty in Section 2.02(b)(iii) as to any such Funded
Contracts or the representation and warranty in Section 2.02(d)(iii) as to any
such Prefunded Contracts in respect of such Contract shall be deemed to have
been incorrect in a manner that materially and adversely affects the
Noteholders, 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 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


                                      -41-

hereunder. The Servicer may engage agents and subservicers to fulfill its duties
hereunder; provided, however, that the Servicer shall remain at all times
personally liable for the acts (and failures to act) of such agents and
subservicers.

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

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

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

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

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

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 Noteholders and the Insurer, to act as such custodian and bailee,
and to hold and deal with such monies and such collections, as custodian and
bailee for the Indenture Trustee, the Issuer and the Insurer, in accordance with
the provisions of this Agreement.

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

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

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


                                      -43-
<PAGE>   48
the Servicer shall not change any material term of a Contract, including but not
limited to the interest rate, the payment amounts or due dates, or the property
securing such Contract.

        SECTION 3.03. REALIZATION UPON CONTRACTS.

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

        SECTION 3.04. INSURANCE.

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

        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


                                      -44-
<PAGE>   49
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 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 Noteholders have the right
to require that the Servicer or Onyx make, any such notation on the related
Financed Vehicles' certificate of title (or, if applicable, in the case of the
State of California, the electronic title record) or fulfill any such additional
administrative requirement of the laws of the state in which a Financed Vehicle
is located.

        SECTION 3.06. COVENANTS, REPRESENTATIONS AND WARRANTIES OF SERVICER.

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

        (a) The Servicer covenants as to the Contracts:

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

                (ii)    The Servicer shall not impair the rights of the
                        Noteholders 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.

                (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
                        conducted, and to enter into and perform its obligations
                        under this Agreement.

                (ii)    The execution and delivery by the Servicer of this
                        Agreement are within the corporate power of the Servicer
                        and have been duly authorized by all necessary corporate
                        action on the part of the Servicer. Neither the
                        execution and delivery of this Agreement, nor the
                        consummation of the transactions herein contemplated,
                        nor compliance with the provisions hereof, will conflict
                        with or result in a breach of, or constitute a default
                        under, any of the provisions of any law, governmental
                        rule, regulation, judgment, decree or order binding on
                        the Servicer or its properties or the Certificate of
                        Incorporation or Bylaws of the Servicer, or any of the
                        provisions of any indenture, mortgage, contract or other
                        instrument to which the Servicer is a party or by which
                        it is bound or result in the creation or imposition of
                        any lien, charge or encumbrance upon any of its property

                        contract or other instrument.

                (iii)   Other than consents that have been obtained prior to the
                        Closing Date, the Servicer is not required to obtain the
                        consent of any other party or any consent, license,
                        approval or authorization, or registration or
                        declaration with, any governmental authority, bureau or
                        agency in connection with the execution, delivery,
                        performance, validity or enforceability of this
                        Agreement.

                (iv)    This Agreement has been duly executed and delivered by
                        the Servicer and, assuming the due authorization,
                        execution and delivery hereof by the Issuer, the Trust
                        Agent and the Indenture Trustee, constitutes a legal,
                        valid and binding obligation of the Servicer enforceable
                        against the Servicer in accordance with its terms
                        (subject to applicable bankruptcy and insolvency laws
                        and other similar laws affecting the enforcement of
                        creditors' rights generally).

                (v)     There are no actions, suits or proceedings pending or,
                        to the knowledge of the Servicer, threatened against or
                        affecting the Servicer, before or by any court,
                        administrative agency, arbitrator or governmental body
                        with respect to any of the transactions contemplated by
                        this Agreement, or which will, if determined


                                      -46-

                        adversely to the Servicer, materially and adversely
                        affect it or its business, assets, operations or
                        condition, financial or otherwise, or materially and
                        adversely affect the Servicer's ability to perform its
                        obligations under this Agreement. The Servicer is not in
                        default with respect to any order of any court,
                        administrative agency, arbitrator or governmental body
                        so as to materially and adversely affect the
                        transactions contemplated by the above-mentioned
                        documents.

                (vi)    The Servicer has obtained or made all necessary
                        consents, approvals, waivers and notifications of
                        creditors, lessors and other nongovernmental persons, in
                        each case, in connection with the execution and delivery
                        of this Agreement, and the consummation of all the
                        transactions herein contemplated.

        SECTION 3.07. PURCHASE OF CONTRACTS UPON BREACH BY SERVICER.

        The Servicer or the Issuer shall inform the other party and the
Indenture Trustee and the Insurer promptly, in writing, upon the discovery of
any breach of the covenants, representations and warranties set forth in Section
3.06 or of the covenants set forth in Sections 3.02 or 3.05. Unless the breach
shall have been cured within 30 days following such discovery or receipt of
notice of such breach, the Servicer shall purchase any Contract materially and
adversely affected by such breach from the Issuer. As consideration for the
Contract, the Servicer shall remit the Purchase Amount on the Business Day
preceding the Servicer Report Date next succeeding the end of such 30-day cure
period in the manner specified in Section 4.02(a). The sole remedy of the
Issuer, the Indenture Trustee, or the Noteholders with respect to a breach of
Section 3.02, 3.05 or 3.06 shall be to require the Servicer to purchase
Contracts pursuant to this Section 3.07; provided, however, that the Servicer
shall indemnify the Owner Trustee, the Indenture Trustee, the Insurer, the
Issuer, the Custodian and the Noteholders 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.

        Any successor Servicer appointed pursuant to Section 7.02 shall not be
obligated to purchase Contracts pursuant to this Section 3.07 with respect to
any breaches by any prior Servicer.

        SECTION 3.08. SERVICING COMPENSATION.

        As compensation for the performance of its obligations under this
Agreement and subject to the terms of this Section, the Servicer shall be
entitled to receive on each Distribution Date the Servicing Fee in respect of
each Contract that was Outstanding at the beginning of the Collection Period
ending immediately prior to such Distribution Date; provided, however, that with
respect to the first Distribution Date the Servicer will be entitled to receive
the Servicing Fee in respect of each Outstanding Initial Contract as of the
Initial Cut-Off Date. As servicing compensation in addition to the Servicing
Fee, the Servicer shall be entitled (i) to retain all late payment charges,
extension fees and similar items paid in respect of Contracts, (ii) to receive,
in respect of each Rule of 78's Contract that is prepaid in full prior to its
Maturity Date, the amount by which the outstanding principal balance of such
Contract (determined in accordance with the Rule of 78's Method) exceeds the
Principal Balance of such Contract at the time of such prepayment and (iii) to
receive all investment earnings on funds credited to the Collection Account and
the Payahead Account;


                                      -47-

pursuant to clause (ii) of this Section shall be deposited in the Spread Account

all expenses incurred by it in connection with its servicing activities
hereunder and shall not be entitled to reimbursement of such expenses except to
the extent provided in Section 3.03.

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

            DISTRIBUTIONS; SPREAD ACCOUNT; STATEMENTS TO NOTEHOLDERS

        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 2000-B,
                        The Chase Manhattan Bank, Indenture Trustee" (the
                        "COLLECTION ACCOUNT");

                (ii)    an account denominated "Payahead Account - OT 2000-B,
                        The Chase Manhattan Bank, as agent" (the "PAYAHEAD
                        ACCOUNT");

                (iii)   an account denominated "Spread Account - OT 2000-B, The
                        Chase Manhattan Bank, Indenture Trustee" (the "SPREAD
                        ACCOUNT");

                (iv)    an account denominated "Note Distribution Account - OT
                        2000-B, The Chase Manhattan Bank, Indenture Trustee"
                        (the "NOTE DISTRIBUTION ACCOUNT");

                (v)     an account denominated "Prefunding Account - OT 2000-B,
                        The Chase Manhattan Bank, Indenture Trustee" (the
                        "PREFUNDING ACCOUNT"); and

                (vi)    an account denominated "Capitalized Interest Account -
                        OT 2000-B, The Chase Manhattan Bank, Indenture Trustee"
                        (the "CAPITALIZED INTEREST 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 2000-B, The Chase Manhattan Bank, Indenture Trustee" (the
"PAYMENT ACCOUNT" and, together with the accounts described in clauses (i)
through (vi) above, the "TRUST ACCOUNTS"). The Trust Accounts shall be


                                      -53-
<PAGE>   58
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 Notes and to the Contracts and, if applicable, the related Eligible
Investments. The location and account numbers of the Trust Accounts as of the
Closing Date are set forth on Schedule II. The Servicer shall give the Issuer,
the Owner Trustee, the Trust Agent, the Indenture Trustee and the Insurer at
least five Business Days' written notice of any change in the location of any
Trust Account and any related account identification information. All amounts,
financial assets and investment property held in, deposited in or credited to,
from time to time, the Trust Accounts (other than the Payahead Account and
investment income credited to the Collection Account and the Capitalized
Interest Account) shall be part of the Trust Property and all amounts, financial
assets and investment property held in, deposited in or credited to, from time
to time, the Collection Account, the Spread Account, the Prefunding Account and
the Capitalized Interest Account shall be invested by the Indenture Trustee in
Eligible Investments pursuant to Section 4.01(c).

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

        (c) All funds in the Collection Account, the Spread Account, the
Prefunding Account and the Capitalized Interest Account shall be invested by the
Indenture Trustee (if the Indenture Trustee maintains the applicable account),
or on behalf of the Indenture Trustee by the depository institution maintaining
such account, in Eligible Investments only upon the written direction from the
Servicer or the Insurer, as described below. Subject to the limitations set
forth herein, the Servicer may direct the depository institution maintaining the
Collection Account, the Spread Account, the Prefunding Account and the
Capitalized Interest Account in writing (with a copy of such direction to the
Indenture Trustee, if the Indenture Trustee is not the applicable depository
institution) to invest funds in the Collection Account, the Spread Account, the
Prefunding Account and the Capitalized Interest Account in Eligible Investments;
provided that (i) in the absence of such directions from the Servicer, the
Insurer may so direct, and (ii) at any time during the continuance of a Servicer
Default, only the Insurer, or for so long as an Insurer Default shall have
occurred and be continuing, only the Issuer, may give such investment
directions. All such investments shall be in the name of the Indenture Trustee
for the benefit of the Noteholders. All income or other gain from investment of
monies deposited in or credited to the Collection Account shall be paid by the
depository institution maintaining the Collection Account to the Servicer
monthly. All income or other gain from investment of monies deposited in or
credited to the Spread Account, the Prefunding Account and the Capitalized
Interest Account shall be deposited in or credited to such account immediately
upon receipt, and any loss resulting from such investment shall be charged to
such account. The


                                      -54-
<PAGE>   59
maximum permissible maturities of any investments of funds in the Collection
Account, the Spread Account and the Capitalized Interest Account on any date
shall not be later than the Servicer Report Date immediately preceding the
Distribution Date next succeeding the date of such investment; provided,
however, that if the Indenture Trustee is maintaining the applicable account,
such funds may be invested by the Indenture Trustee in Eligible Investments of
the entity that is serving as Indenture Trustee (or an entity which meets the
criteria in clauses (i)(b) or (i)(c) of the definition of Eligible Account) that
mature on the Business Day prior to such Distribution Date. The maximum
permissible maturity of any investments of funds in the Prefunding Account on
any date shall not be later than the next Business Day. No investment in
Eligible Investments may be sold prior to its maturity. The funds on deposit in
the Payment Account and the Note Distribution Account shall remain uninvested.

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

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

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


                                      -55-
<PAGE>   60
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 Amount, if any, for such Distribution Date, separately identifying the
amount of the Policy Claim Amount payable in respect of each Class of Notes.
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. 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).

        (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.

        SECTION 4.03. DISTRIBUTIONS.

        On each Distribution Date, based solely on the Distribution Date
Statement, the Indenture Trustee will apply the Net Collections available from
the Payment Account, along with any amounts deposited into the Payment Account
from the Prefunding Account and the Capitalized Interest 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
                        accrued and unpaid Servicing Fees with respect to one or
                        more prior Collection Periods;

                (ii)    to the Indenture Trustee, the Owner Trustee and the
                        Trust Agent, any accrued and unpaid fees of the
                        Indenture Trustee, the Owner Trustee and the Trust
                        Agent, in each case to the extent such fees have not
                        been previously paid by the Servicer or the
                        Administrator;

                (iii)   to the Note Distribution Account, the Note Interest
                        Distributable Amount to be paid first to the Holders of
                        the Class A Notes at their respective Interest Rates and
                        second to the Holders of the Class B Notes;

                (iv)    to the Note Distribution Account, if such Distribution
                        Date is a Note Final Scheduled Distribution Date for any

                        paid first to the Holders of the Class A-1 Notes until
                        the principal amount of the Class A-1 Notes has been

                        under the Insurance Agreement;

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

                (ix)    any amounts remaining after distribution of the

                        shall be deposited into the Spread Account.

Any amounts deposited in the Payment Account pursuant to 4.04(b) with respect to
a Distribution Date and any amounts received by the Indenture Trustee as a
result of a claim under the Policy that represent the Deficiency Amount with
respect to such Distribution Date shall be applied by the Indenture Trustee
solely to make the deposits and distributions referred to in clauses (i) through

Collections (plus amounts transferred to the Payment Account from the Prefunding
Account, representing earnings from investments therein, and amounts transferred
to the Payment Account from the Capitalized Interest Account, if any) with
respect to such Distribution Date, after application as provided above, were


                                      -57-
<PAGE>   62
insufficient to make such deposit or distribution. In addition, if the Insurer
pays any amounts to the Indenture Trustee with respect to a Distribution Date in
connection with the Insurer's election to pay, as provided in the Policy, all or
a portion of any shortfalls in the amount of Net Collections (plus amounts
transferred to the Payment Account from the Prefunding Account, representing
earnings from investments therein, and amounts transferred to the Payment
Account from the Capitalized Interest Account, if any) with respect to such
Distribution Date available to distribute the amounts referred to in clause (vi)
above, the Indenture Trustee shall distribute the amounts so received from the
Insurer as provided in such clause.

        SECTION 4.04. SPREAD ACCOUNT.

        (a) The Spread Account will be held for the benefit of the Noteholders
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, clauses (i) though (iv) with respect
to such Distribution Date exceeds the amount of Net Collections (plus amounts
transferred to the Payment Account from the Prefunding Account, representing
earnings from investments therein, and amounts transferred to the Payment
Account from the Capitalized Interest Account, if any) available with respect to
such Distribution Date. The Indenture Trustee shall deposit any such funds
withdrawn from the Spread Account into the Payment Account to be distributed
pursuant to Section 4.03. 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 Note 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 Noteholders 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 Noteholders 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 Noteholders (collectively, the "POTENTIAL
PREFERENCE PARTIES") shall have occurred during the period ending ninety-one
(91) days after payment in full to the Noteholders of all amounts payable with


                                      -58-
<PAGE>   63
respect to the Notes 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 or the Noteholders. 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 Noteholders and the Insurer may be required to pay and then to
the holders of the Residual Interests, pro rata in proportion to their
Percentage Interests. If it is determined that any such payment is not
recoverable, the Insurer shall direct the Indenture Trustee in writing to
release all amounts on deposit in the Spread Account to the holders of the
Residual Interests, pro rata in proportion to their Percentage Interests, upon
receipt by the Insurer of both a final order determining that such payments are
not recoverable and an opinion of nationally recognized bankruptcy counsel to
the effect that such appeal is final and not subject to appeal. For purposes of
compliance with this Section 4.04(d), the Indenture Trustee shall be entitled to
rely on written instructions from the Insurer.

        (e) In the event any of the holders of the Residual Interests seek to
have the amounts remaining on deposit in the Spread Account released to holders
of the Residual Interests prior to the expiration of the ninety-one (91) day
period specified in Section 4.04(d) above, then, if (i) amounts payable with
respect to the Notes have been fully paid to the Noteholders, (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 Noteholders, 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 NOTEHOLDERS.

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

obligations of the Seller hereunder and executes and 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 Trust Agent, the Indenture
Trustee and the Insurer, which contains an assumption by such successor entity
of the due and punctual performance and observance of each covenant and
condition to be performed or observed by the Seller under this Agreement.

        SECTION 5.03. LIMITATION ON LIABILITY OF SELLER AND OTHERS.

        The Seller and any director or officer or employee or agent of the
Seller may rely in good faith on any document of any kind, prima facie properly
executed and submitted by any Person respecting any matters arising hereunder.

any legal action that shall not be incidental to its obligations under this
Agreement, and that in its opinion may involve it in any expense or liability.

        SECTION 5.04. SELLER NOT TO RESIGN.

        Subject to the provisions of Section 5.02, the Seller shall not resign

provided herein or in any Basic Document. Notes so owned by or pledged to the
Seller or such Affiliate shall have an equal and proportionate benefit under the
provisions of this Agreement, without preference, priority or distinction as
among all Classes of the Notes.

                                   ARTICLE VI

                                  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
Noteholders from and against any and all costs, expenses, losses, damages,
claims and liabilities, arising out of or resulting from the use, ownership or
operation by the Servicer or any Affiliate thereof of a Financed Vehicle.

        (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


                                      -64-
<PAGE>   69
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 Notes, 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 Notes) 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 Noteholders 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 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.


                                      -65-
<PAGE>   70
        (f) 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.

        (g) 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
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


                                      -66-
<PAGE>   71
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 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 or any Noteholder, or the Insurer of any provision of the
Notes, the Insurance Agreement or this Agreement.

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

        SECTION 6.05. LIMITATION ON LIABILITY OF SERVICER AND OTHERS.

        Neither the Servicer nor any of the directors, officers, employees or
agents of the Servicer shall be under any liability to the Issuer or the
Noteholders, 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 Noteholders under this Agreement
and the other Basic Documents.

                                     DEFAULT

        SECTION 7.01. EVENTS OF DEFAULT.

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

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

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

        (c) any failure on the part of the Seller or the Servicer duly to
observe or to perform in any material respect any other covenants or agreements
of the Seller or the Servicer set forth in this Agreement or any other Basic
Document, which failure shall (i) materially and adversely affect the rights of
the Noteholders, the Insurer, the Issuer, the Owner Trustee or the Indenture
Trustee and (ii) continue unremedied for a period of 30 days after the date on
which written notice of such failure, requiring the same to be remedied, shall
have been given (A) to the Seller or the Servicer, as the case may be, by the
Insurer, the Issuer, the Owner Trustee or the Indenture Trustee or (B) to the
Seller or the Servicer, as the case may be, and to the Issuer and the Indenture
Trustee by the Holders of Notes, acting together as a single class, evidencing
in the aggregate not less than 25% of the outstanding amount of the Notes, or
(2) so long as no Insurer Default has occurred and is continuing, by the
Insurer;

        (d) the entry of a decree or order for relief by a court or regulatory
authority having jurisdiction in respect of the Servicer or the Seller in an
involuntary case under the federal bankruptcy laws, as now or hereafter in
effect, or another present or future, federal or state, bankruptcy, insolvency
or similar law, or appointing a receiver, liquidator, assignee, trustee,
custodian, sequestrator or other similar official of the Servicer or the Seller
or of any substantial part of its property, or ordering the winding up or
liquidation of the affairs of the Servicer or the Seller and the continuance of
any such decree or order unstayed and in effect for a period of 60 consecutive
days or the commencement of an involuntary case under the federal bankruptcy
laws, as now or hereinafter in effect, or another present or future federal or
state bankruptcy, insolvency or similar law and such case is not dismissed
within 60 days;

        (e) the commencement by the Servicer or the Seller of a voluntary case
under the federal bankruptcy laws, as now or hereafter in effect, or any other

the consent by the Servicer or the Seller to the appointment of or taking
possession by a receiver, liquidator, assignee, trustee, custodian, sequestrator
or other similar official of the Servicer or the Seller or of any substantial
part of its property or the making by the Servicer or the Seller of an
assignment for the benefit of creditors or the failure by the


                                      -68-
<PAGE>   73
Servicer or the Seller generally to pay its debts as such debts become due or
the taking of corporate action by the Servicer or the Seller in furtherance of
any of the foregoing;

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

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

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

then and in each and every case, so long as such Servicer Default shall not have
been remedied, either (i) the Insurer, provided no Insurer Default has occurred
and is continuing or (ii) if an Insurer Default has occurred and is continuing
Holders evidencing not less than 25% of the outstanding principal amount of the
Highest Priority Class, acting together as a single class or the Indenture
Trustee acting on behalf of the Noteholders, and not the Seller, by notice then
given in writing to the Servicer (and to the Insurer, the Indenture Trustee and
the Issuer if given by the Noteholders) 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 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.

<PAGE>   74
        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 or the Noteholders pursuant to Section 7.01,
or upon the resignation of the Servicer pursuant to Section 6.04 in the event
that the Insurer is not entitled to appoint a successor servicer by operation of
Section 9.08, (i) if the Notes have not been paid in full, the Indenture Trustee
shall be the Successor Servicer, and (ii) if the Notes have been paid in full,
the Owner Trustee, acting at the direction of the Holders of Residual Interest
Instruments evidencing not less than 51% of the Percentage Interests 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 RESIDUAL INTERESTHOLDERS.

        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 Residual Interestholders at their respective addresses appearing in
the Certificate Register, and the Indenture Trustee shall give prompt written
notice thereof to Noteholders at their respective addresses appearing in the
Note Register.

        SECTION 7.04. WAIVER OF PAST DEFAULTS.

        Upon the occurrence of a Servicer Default, unless an Insurer Default
shall have occurred and be continuing, the Insurer, and only the Insurer, may
waive any default by the Servicer or the Seller, as the case may be, in the
performance of its obligations under this Agreement except a Servicer Default in
making any required deposits to or payment from the Trust Accounts in accordance
with this Agreement. Upon the occurrence of a Servicer Default, if an Insurer
Default has occurred and is continuing, Holders evidencing not less than 51% of
the outstanding principal amount of the Highest Priority Class, on behalf of all
Noteholders, 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


                                      -70-
<PAGE>   75
except a Servicer Default in making any required deposits to or payment from the
Trust Accounts in accordance with this Agreement. A Servicer Default in making
any required deposits to or payment from the Trust Accounts in accordance with
this Agreement may only be waived with the consent of the Insurer (if no Insurer
Default shall have occurred and be continuing) and Holders evidencing 100% of
the outstanding principal amount of the Notes. No such waiver shall impair the
Insurer's or the Noteholders' 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. Any Preference Amounts paid by the
Insurer shall be reimbursed to the Insurer as provided in Section 4.03 and
4.04(b). Each Noteholder, by its purchase of Notes, 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 Noteholder in the
conduct of any Insolvency Proceeding, including, without limitation, all rights
of any party to an adversary proceeding action with respect to any court order
issued in connection with any such Insolvency Proceeding.

                                  ARTICLE VIII

                                   TERMINATION

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

        (a) On each Distribution Date as of which the Pool Balance is 10% or
less of the Original Pool Balance, the Servicer shall have the option to
purchase the remaining Contracts from the Trust. Notice of the exercise of such
option shall be given by the Servicer to the Issuer, the Trust Agent, the
Indenture Trustee and the Insurer not later than the 10th day prior to the
specified Distribution Date and not earlier than the 15th day of the month prior
to the month of the specified Distribution Date. To exercise such option, the
Servicer shall pay to the Indenture Trustee for the benefit of the Noteholders,
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
Notes 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


                                      -71-
<PAGE>   76
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 Residual
Interestholders 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.

        SECTION 8.02. TRANSFER TO THE INSURER.

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

                                   ARTICLE IX

                                  MISCELLANEOUS

        SECTION 9.01. AMENDMENT.

        (a) This Agreement may be amended by the Issuer, the Seller, the
Servicer, the Indenture Trustee and the Trust Agent, collectively, with the
prior written consent of the Insurer, but without the consent of any
Noteholders, 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 Noteholder; and provided, further, that any such
amendment shall be deemed not to materially and adversely affect the interests
of any Noteholder if the Person requesting the amendment obtains a letter or
confirmation from each Rating Agency to the effect that such amendment would not
result in a downgrading or withdrawal of the ratings then assigned to the
applicable Notes 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 the Holders of Notes evidencing in the aggregate not less than 51%
of the principal amount of the Notes then outstanding, acting together as a
single class, for the purpose of adding any provisions to or changing in any


                                      -72-

manner or eliminating any of the provisions of this Agreement, or of modifying
in any manner the rights of the Noteholders; 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 (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.

        (c) Promptly after the execution of any such amendment or consent, the
Indenture Trustee shall furnish the written notification of the substance of
such amendment or consent to each Noteholder, respectively.

        (d) It shall not be necessary for the consent of Noteholders 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 of the execution thereof shall be subject to such
reasonable requirements as the Indenture Trustee may prescribe. Any consent by a
Noteholder to an amendment of the Agreement shall be conclusive and binding on
such Noteholder and upon all future Noteholders of such Note and of any Note
issued upon the transfer thereof or in exchange thereof or in lieu thereof
whether or not notation of such consent is made upon such Note.

        (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 Noteholders, the Indenture Trustee, the
Trust Agent and the Insurer in the Contracts and in the proceeds thereof. The
Servicer shall deliver (or cause to be delivered) to the Trust Agent and the
Indenture Trustee file- stamped copies of, or filing receipts for, any document
filed as provided above, as soon as available following such filing.

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

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

        (d) The Servicer shall maintain or cause to be maintained accounts and
records as to each Contract accurately and in sufficient detail to permit (i)
the reader thereof to know at any time the status of such Contract, including
payments and recoveries made and payments owing (and the nature of each) and
(ii) reconciliation between payments or recoveries on (or with respect to) each
Contract and the amounts from time to time deposited in or credited to the
Collection Account and the Payahead Account in respect of such Contract.

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

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

        (g) The Servicer shall permit the Owner Trustee, the Trust Agent, the
Indenture Trustee and the Insurer and their respective agents, at any time
during normal business hours, to inspect, audit and make copies of and abstracts
from the Servicer's records regarding any Contract.

        (h) Upon request, the Servicer shall furnish to the Owner Trustee, the
Trust Agent, the Indenture Trustee and the Insurer, within five Business Days, a

reconciliation of such list to the Schedule of Contracts and to each of the
Distribution Date Statements furnished before such request indicating removal of
Contracts from the Trust.

and the Insurer:

                        necessary fully to preserve and protect the interest of
