                  (ii) Each Plan which is intended to be qualified under Section

                  (iii) Neither it nor any ERISA Affiliate maintains or
         contributes to any employee welfare benefit plan within the meaning of

         ERISA.

                  (iv) No Plan has incurred any accumulated funding deficiency
         (as defined in Section 302 of ERISA and 412(a) of the Code), whether or

         a Plan amendment that results in an increase in current liabilities for
         the plan year.

                  (m) Treatment of Transaction. It has not prepared any
financial statement which accounts for the transactions contemplated hereby in
any manner other than the sale of the Purchased Contracts by it, and it has not
in any other respect accounted for or treated the transactions in the Purchased

                  (s) Year 2000 Compliance.

                  (i) It has (a) initiated a review and assessment of all areas
         within its and each of its Subsidiaries' business and operations
         (including those affected by suppliers, vendors and customers) that
         could be adversely affected by the "Year 2000 Problem" (that is, the
         risk that computer applications used by it or any of its Subsidiaries
         (or suppliers, vendors and customers) may be unable to recognize and
         perform properly date-sensitive functions involving certain dates prior
         to and any date after December 31, 1999), (b) developed a plan and
         timeline for addressing the Year 2000 Problem on a timely basis, and
         (c) to date, implemented that plan in accordance with that timetable.
         Based on the foregoing, it believes that all computer applications
         (including those of its suppliers, vendors and customers) that are
         material to its or any of its Subsidiaries' business and operations are
         reasonably expected on a timely basis to be able to perform properly
         date-sensitive functions for all dates before and after January 1, 2000
         (that is, be "Year 2000 Compliant"), except to the extent that a
         failure to do so could not be reasonably expected to have a material
         adverse effect on it or on the Program, or result in a Wind-Down Event.

                  (ii) It (a) has completed a review and assessment of all
         computer applications (including, but not limited to those of its
         suppliers, vendors, customers, and any third party servicers), which
         are related to or involved in the origination, collection, management
         or servicing of the Purchased Receivables (the "Receivables Systems")
         and (ii) has determined that such Receivable Systems are Year 2000
         Compliant or will be Year 2000 Compliant on or before December 31, 1999
         and thereafter.

                  (iii) The costs of all assessment, remediation, testing and
         integration related to its plan for becoming Year 2000 Compliant will
         not have a material adverse effect on its financial condition or
         operations.

                  Section 4.2. Representations and Warranties of the Seller
Concerning Contracts. On each Purchase Date the Seller represents and warrants
to Finco and the Program Manager as follows:

                  (a) Eligible Contract. Each Contract to be sold by it on such
day is an Eligible Contract.

                  (b) Liens. Each Contract to be sold by it on such day is owned
by it free and clear of any Lien or claim of any kind or any offset and, upon
transfer to Finco pursuant to this Agreement, Finco will acquire a valid
ownership interest in each Purchased Contract free and clear of any Lien or
claim of any kind or any offset and no effective financing statement or other
instrument similar in effect covering any such Purchased Contract shall at any
time be on file in any recording office except those relating to this Agreement
and the transactions contemplated hereby.



                                       9
<PAGE>   13

                  (c) Compliance with Laws. Each Contract to be sold by it on
such day complies with all laws and regulations applicable thereto, including,
without limitation, all consumer credit laws.

                  (d) Enforceable Obligations. Each Contract to be sold by it on
such day is in full force and effect and represents a legal, valid and binding
obligation of the Obligor enforceable against the Obligor in accordance with its
terms (except as enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium or similar laws affecting the
enforceability of creditors' rights generally and by general equitable
principles whether considered in proceedings in equity or at law) and
constitutes "chattel paper" under the UCC in effect in the state in which the
principal place of business of the Seller is located.

                  (e) Valid Sale. The sale pursuant to this Agreement by the
Seller and the purchase by Finco of the Purchased Contracts on such Purchase
Date constitutes and will constitute a valid sale of such Purchased Contracts
and the other Collateral and the proceeds thereof, which sale is and will be
enforceable against the Seller and all existing and future creditors of the
Seller and all subsequent purchasers from the Seller or Finco of any of the
Purchased Contracts. Upon the filing of the financing statements described in
Section 4.1(o) with the Secretary of State of the State of California evidencing
the sale of the Purchased Contracts to Finco and, in the case of Purchased
Contracts hereafter created and the proceeds thereof, upon the sale, transfer
and assignment thereof to Finco, Finco shall have a first priority perfected
ownership interest in the Purchased Contracts and the other Collateral.

                  (f) Credit and Collection Policy. The Credit and Collection
Policy has been complied with in all respects with respect to each Contract to
be sold by it on such day and no change has been made in the character of its
business or (except to the extent required by law and of which CapMAC and the
Program Manager have received written notice prior to the applicable Purchase
Date) in the Credit and Collection Policy, which change could, in either case,
impair the collectibility of any Purchased Contract.

                  (g) Contract Information. The Contract Information delivered
by the Seller to Finco (if the Seller is the Servicer) or by the Seller to the
Servicer (if the Seller is not the Servicer) with respect to each Purchased
Contract on such Purchase Date is true and correct.

                  (h) Inspections. Each Contract that is not originated by a
Vehicle Dealer has been inspected by CSI Escrow Document Services, Inc., the
Servicer or any other inspection company reasonably acceptable to the Program
Manager ("Inspector"), and the Inspector has issued a written inspection report
(the "Vehicle Condition Report") describing the Vehicle and the equipment in the
Vehicle, confirming the vehicle identification number and certifying that the
Vehicle is in good repair.

                  (i) Repossessed Vehicles. As of the last day of any month, the
aggregate Outstanding Balance of Purchased Contracts secured by Vehicles
previously repossessed by the Seller (each a "Repossessed Vehicle") shall not
exceed 1% of the aggregate Outstanding Balance of all Purchased Contracts then
financed by Triple-A One Loans.



                                       10

                  (j) Documentation. All documents used by the Seller in
connection with the purchase or origination of Contracts (including, without
limitation, any security agreement, loan contract or promissory note), and all
certificates of title and entries in the Paperless Title System for Vehicles
securing Contracts use the following words to identify the lender, secured party
or obligee: (i) "Onyx Acceptance Corporation" or some abbreviation thereof which
unmistakably identifies the Seller as secured party or (ii) "ABNI, Inc." or
"C.U. Acceptance Corporation"; provided, however, that the name "ABNI, Inc." or
"C.U. Acceptance Corporation" may only be used in such documents with respect to
Contracts for which the Program Manager has received an opinion of counsel
addressed to the Program Manager satisfactory in form and substance to the
Program Manager from counsel to the Seller acceptable to the Program Manager in
its reasonable judgment, to the effect that (x) under the law of the state in
which the related Vehicle is registered, the Seller has a first priority
perfected security interest in the related Vehicle notwithstanding the use of
such name and (y) under applicable law, the use of such name rather than "Onyx
Acceptance Corporation" or some other abbreviation thereof which unmistakably
identifies the Seller as secured party will not affect the Seller's ownership
interest in the Contracts and the Seller's security interest in the related
Vehicles.

                  (k) Lienholder on Title. Prior to January 1, 1997, the
Seller's lien in any Vehicle registered in California securing a Purchased
Contract was obtained by submitting the appropriate documents to the California
Department of Motor Vehicles and was not obtained by electronically transmitting
information to such department of Motor Vehicles.

                  (l) Contract Files. It has delivered to Finco the Files
relating to each Contract sold to Finco on such Purchase Date; provided,
however, that as to any Purchased Contract, if (a) as evidenced by an opinion of
counsel delivered to and in form and substance satisfactory to the Program
Manager and the Collateral Agent, (x) an optical image or other representation
of the Files are enforceable in the relevant jurisdictions to the same extent as
the original of such document and (y) such optical image or other representation
does not impair the ability of an owner of such Contract to transfer its
interest in such Contract, and (b) the retention of such documents in such
format will not result in a reduction of the then current rating of the
transaction and Triple-A One, without regard to the Surety Bonds, such optical
image or other representation may be held by the Servicer, as custodian for
Triple-A One in lieu of the Files.

                  Section 4.3. Covenants of Seller. The Seller covenants and
agrees with Finco that so long as this Agreement shall remain in effect:

                  (a) Corporate Existence. It will preserve and maintain its
corporate existence, rights, franchises and privileges in the jurisdiction of
its incorporation, and qualify and remain qualified and in good standing as a
foreign corporation in each jurisdiction where the failure to maintain such
existence, rights, franchises, privileges and qualifications could affect (i)
the rights or interests of Finco hereunder, (ii) the collectibility of any
Contract or (iii) its ability to perform its obligations hereunder.

                  (b) Master Record of the Contracts. It will, at its own cost
and expense, retain a master record of the Contracts sold by it and copies of
all documents and records relating to 



                                       11
<PAGE>   15

each such Purchased Contract and, at its own cost and expense, mark such master
record to the effect that the Purchased Contracts listed thereon have been sold
to Finco.

                  (c) Recovery Procedure. It will maintain its Recovery
Procedure in good operational order and permit representatives of Finco access
to its management employees to fully discuss such Recovery Procedure during
normal business hours. If it obtains a third party to maintain such Recovery
Procedure, then it shall arrange to permit representatives of Finco access
during normal business hours to such system to make such inspections and
examinations as it deems necessary.

                  (d) Conduct of Business. It will comply with all applicable
laws, rules, regulations, and orders with respect to it, its business and
properties and all Contracts it originates or purchases, the failure to comply
with which could have a material adverse affect on it or on such Contracts.

                  (e) Defense of the Purchased Contracts. It will not create,
permit or suffer to exist, and will take such other actions as are necessary to
remove, any Lien, claim or right in, to or on any Purchased Contract, and will
defend the right, title and interest of Finco in and to the Purchased Contracts
against the claims and demands of all Persons whomsoever, other than (i) the
Liens created hereby and by the transactions contemplated hereby or (ii) Liens
for taxes which are being contested in good faith by appropriate proceedings,
provided that adequate reserves with respect thereto are maintained on the books
of Finco in conformity with GAAP.

                  (f) Notice. It will advise Finco (with a copy to the Program
Manager) in detail, of (i) any Lien asserted or claim made against any Purchased
Contract, (ii) the occurrence of any breach by it of any of its representations,
warranties and covenants contained herein, (iii) the occurrence of any Wind-Down
Event or Unmatured Wind-Down Event, (iv) any litigation, investigation or
proceeding which may exist at any time between it and any Governmental Authority
or other Person or default or event of default under any of its Contractual
Obligations, which in either case could have a material adverse effect on the
value of the Purchased Contracts or its ability to satisfy its obligations
hereunder and (v) any material adverse change in its business, properties,
operations or financial or other condition or the occurrence of any other event
which could have an adverse effect on the collectibility or value of the
Purchased Contracts, in each case immediately upon ascertaining or obtaining
knowledge of any of the foregoing. Each notice pursuant to this subsection shall
be accompanied by a statement of a Responsible Officer setting forth details of
the occurrence referred to therein and stating what action it proposes to take
with respect thereto.

                  (g) Maintain Interest.

                  (i) It shall, with respect to any and all Purchased Contracts
         and security interests in Vehicles sold hereunder, at its expense,
         perform all acts and execute all documents requested by Finco or the
         Program Manager, as the case may be, at any time to evidence, perfect,
         maintain and enforce the ownership interest and security interest,
         respectively, of Finco and the Program Manager therein and the first
         priority of such ownership interest and security interest,
         respectively. It will, at the request of a duly

         authorized officer of Finco or the Program Manager, execute and deliver
         financing statements evidencing the ownership interest of Finco in all
         of the foregoing, which financing statements must be satisfactory in
         form and substance to the Program Manager, and the Seller authorizes
         Finco to file one or more financing statements signed only by Finco. It
         also hereby irrevocably appoints Finco its attorney-in-fact to file one
         or more financing statements signed on behalf of the Seller by Finco as
         the attorney-in-fact of the Seller.

                  (ii) It will not, without providing 30 days' notice to Finco
         and the Program Manager, and without filing such amendments to any
         previously filed financing statements as Finco or the Program Manager
         may require, (A) change the location of its chief executive office or
         the location of the offices where the documents and records relating to
         the Contracts are kept or (B) change its name, identity or corporate
         structure in any manner which might make any financing statement or
         continuation statement filed by it pursuant to the transactions
         contemplated hereby seriously misleading within the meaning of 9-402(7)
         of any applicable enactment of the UCC.

                  (h) Annual Certificate. It will deliver to Finco, the
Collateral Agent and the Program Manager concurrently with the delivery of its
annual financial statements delivered pursuant to subsection (l) of this Section
4.3, a Certificate of a Responsible Officer dated as of a date during the 90-day
period following the end of the immediately preceding fiscal year, either (i)
stating that such action has been taken with respect to the recording,
registering, filing, re-recording, re-registering and re-filing of financing

necessary to preserve and protect the interest of Finco in and to the Purchased
Contracts and Vehicles and reciting the details of such action or referring to
opinions of counsel in which such details are given and stating what action is
required to be taken in the subsequent 13-month period to preserve and protect
such interest or (ii) stating that no such action is necessary to preserve and
protect such interest.

                  (i) Credit and Collection Policy. It will (i) at all times
comply with its Credit and Collection Policy, including, but not limited to, its
customary practices with respect to granting rebates and discounts and (ii) not
change the terms of the contracts and agreements relating to the Contracts
(including, without limitation, the terms of sale or the interest rate charged
to any Obligor under any Contract), its normal policies and procedures with
respect to the servicing thereof (including, without limitation, the amount and
timing of finance charges, fees and write-offs) or its Credit and Collection
Policy, except with the prior written consent of CapMAC or as required by any
Requirement of Law (in which case the Servicer shall give CapMAC and the Program
Manager immediate written notice of such Requirement of Law).

                  (j) Collections. If it receives Collections, it agrees to hold
such Collections in trust for the benefit of Finco and any such Collections
received in the Lock-Boxes shall be transferred to the Clearing Account on the

Collections shall be transferred from the Clearing Account to the Collection
Account on the next Business Day after deposit into the Clearing Account.



                                       13
<PAGE>   17

                  (k) Obligations Under the Contracts and Dealer Assignments. It
will duly fulfill all obligations on its part to be fulfilled under or in
connection with each Contract and Dealer Assignment and will do nothing (except
as may be permitted by Section 4.5 hereof) to impair the rights of Finco in the
Purchased Contracts. It agrees that, for the benefit of Finco, it will continue
to make and pursue claims on the Contracts sold by it hereunder to the extent
that any law, regulation or contractual provision requires that it directly make
and pursue such claims, for the benefit of Finco; provided that the Seller
agrees that it is making and pursuing such claims for the benefit of Finco and
its assignees, and that any funds received by the Seller based on such claims
will be transferred to the Clearing Account within one Business Day of being
received and will thereafter be transferred to the Collection Account on the
next Business Day after deposit into the Clearing Account.

                  (l) Financial Statements. It will furnish to Finco (with a

                        SELLER NOTE AND SUBORDINATED NOTE


                  Section 5.1. Seller Note (a) On the Closing Date, Finco shall
issue to the Seller the seller note substantially in the form of Exhibit A (the
"Seller Note"). The principal amount of the Seller Note shall be calculated
pursuant to the Daily Report and, on any day, shall be equal to the Seller
Interest on such day. The Seller Note shall (x) be dated the Closing Date, and
(y) be stated to mature on the Scheduled Maturity Date. Interest on the

                  (a) Seller agrees and confirms that the Seller Note represents
solely an obligation of Finco to make certain payments from funds available
under the Triple-A One Security Agreement and only to the extent, in the manner
and at the times set forth in the Triple-A One Security Agreement, and that the
Seller Note does not represent an interest in, and is not secured by, the
Purchased Contracts, the proceeds thereof or any other Collateral.

                  (b) Finco may at any time and from time to time prepay the
Seller Note, in whole or in part, without premium or penalty.

                  Section 5.2. Restrictions on Transfer of Seller Note. Neither
the Seller Note nor any right of the Seller to receive any payment thereunder,
shall be assigned, transferred, exchanged, pledged, hypothecated, participated
or otherwise conveyed except with the prior written consent of the Program
Manager, which consent shall not be unreasonably withheld or delayed.

                  Section 5.3. Subordinated Note. (a) on the Closing Date,
Finco shall issue to the Seller the subordinated note substantially in the form
of Exhibit B (the "Subordinated Note"). The principal amount of the Subordinated
Note shall be calculated pursuant to the Daily Report and, on any day, shall be
equal to the Subordinated Interest on such day; provided, however, that the
principal amount of the Subordinated Note shall be fixed on and not be
recalculated after the Commitment Termination Date; provided, further, that in
no event shall the principal amount of the Subordinated Note calculated pursuant
to the Daily Report at any time exceed the Required Overcollateralization
Amount.

                  (a) Interest on the principal amount of the Subordinated Note
shall accrue at a rate set forth in the Subordinated Note. Principal and
interest payments on the Subordinated Note may be made to the extent permitted
by the Triple-A One Security Agreement. Principal amounts outstanding on the
Subordinated Note shall increase concurrently with the payment of the Purchase
Price pursuant to the terms of Section 2.3(a)(ii), 2.3(a)(iii) and 2.3(b)
hereof. Principal payments on the Subordinated Note shall become payable only
upon the release of Collateral by the Collateral Agent pursuant to Section 23(b)
of the Triple-A One Security 



                                       21

Agreement. Except to the extent permitted by the Triple-A One Security
Agreement, the Seller agrees not to ask, demand, sue for or take or receive from
Finco in cash or other property, by set-off or in any other manner, (including,
without limitation, from or by way of the Collateral), payment of all or any
part of the Subordinated Note.

                  (b) The Seller agrees upon any distribution of all or any of
the assets of Finco to creditors of Finco upon the dissolution, winding up,
total or partial liquidation, arrangement, reorganization, adjustment,
protection, relief, or composition of Finco or its debts, any payment or
distribution of any kind (including, without limitation, cash, property,
securities and any payment or distribution which may be payable or deliverable
by reason of the payment of any other Debt of Finco being subordinated to the
payment of the Subordinated Note) in respect of the Subordinated Note that
otherwise would be payable or deliverable upon or with respect to the
Subordinated Note, directly or indirectly, by set-off or in any other manner,
including, without limitation, from or by way of the Collateral, shall be paid
or delivered directly to the Collateral Agent for application (in the case of
cash) to or as Collateral (in the case of non-cash property or securities) for
the payment or prepayment in full of, the Obligations (other than the
Subordinated Note) until the Obligations shall have been indefeasibly paid in
full in cash. The Collateral Agent is irrevocably authorized and empowered (in
its own name or in the name of the Seller or otherwise), but shall have no
obligation, to demand, sue for, collect and receive every payment or
distribution referred to in the preceding sentence and give acquittance therefor
and to file claims and proofs of claim and take such other action (including,
without limitation, voting the Subordinated Note and enforcing any security
interest or other lien securing payment of the Subordinated Note) as the
Collateral Agent may deem necessary or advisable for the exercise or enforcement
of any of the rights or interest of Triple-A One. The Seller shall duly and
promptly take such action as the Collateral Agent may request to (i) collect the
Subordinated Note for the account of Triple-A One and to file appropriate claims
or proofs of claim in respect of the Subordinated Note, (ii) execute and deliver
to the Collateral Agent such powers of attorney, assignments or other
instruments as the Collateral Agent may request in order to enable the
Collateral Agent to enforce any and all claims with respect to, and any security
interests and other liens securing payment of, the Subordinated Note, (iii)
collect and receive any and all payments or distributions which may be payable
or deliverable upon or with respect to the Subordinated Note.

                  (c) All payments or distributions upon or with respect to the
Subordinated Note that are received by the Seller contrary to the provisions of
the Operative Documents shall be received in trust for the benefit of Triple-A
One, shall be segregated from other funds and property held by Seller and shall
be forthwith paid over to the Collateral Agent in the same form as so received
(with any necessary endorsement) to be applied (in the case of cash) to, or held
as Collateral (in the case of non-cash property or securities) for the payment
or prepayment in full of, the Obligations (other than the Subordinated Note)
until the Obligations shall have been indefeasibly paid in full in cash. The
Seller agrees that no payment or distribution to Triple-A One pursuant to the
provisions of the Subordinated Note shall entitle the Seller to exercise any
rights of subrogation in respect thereof against Finco until the Obligations
(other than the Subordinated Note) and all principal and interest under the
Seller Note shall have been indefeasibly paid in full in cash. The Seller and
Finco hereby waive promptness, diligence, 



                                       22
<PAGE>   26

notice of acceptance and any other notice with respect to any of the Obligations
and any requirement that the Collateral Agent protect, secure, perfect or insure
any security interest or lien on any property subject thereto or exhaust any
right or take any action against Finco or any other Person or any Collateral.

                  (d) The Subordinated Note is secured by the Collateral
pursuant to the Subordinated Security Agreement, subject to the prior lien of
the Collateral Agent under the Triple-A One Security Agreement. No payments may
be received, directly or indirectly, by the Seller (and if received, the Seller
agrees to return such payments to Finco) on the Subordinated Note unless Finco
has paid all amounts required pursuant to the Triple-A One Security Agreement to
be paid prior to any payments in respect of the Subordinated Note.

                  (e) The Seller agrees and confirms that the Collateral Agent
shall not have any duty whatsoever to the Seller as holder of the Subordinated
Note and that the Collateral Agent shall not be liable to the Seller for any
action taken or omitted to be taken with respect to the Subordinated Note.

                  (f) Prior to the indefeasible payment in full in cash of the
other Obligations, the Seller will not seek to collect any amounts owing under
the Subordinated Note in any manner or exercise or enforce any of its rights
under the Subordinated Security Agreement.

                  (g) The Seller and Finco further agree that at no time
hereafter will any part of the indebtedness represented by the Subordinated Note
be represented by any negotiable instruments or other writings except the
Subordinated Note.

                  (h) The Seller and Finco waive notice of and consent to the
creation of the Triple-A One Loans and any of the other Obligations, any
extensions granted or other action taken by Triple-A One, the Surety Provider,
the Program Manager, the Collateral Agent or the Bank Collateral Agent with
respect thereto, the taking or releasing of Collateral or any obligors or
guarantors for the payment thereof, and the releasing of the Seller or any other
subordinated creditors. No failure or delay by Triple-A One, the Surety
Provider, the Program Manager, the Collateral Agent or the Bank Collateral Agent
to exercise any right granted herein, or in any other agreement or by law shall
constitute a waiver of such right or of any other right.

                  (i) Finco and the Seller agree to execute and deliver to
Triple-A One, the Surety Provider, the Program Manager, the Collateral Agent and
the Bank Collateral Agent such additional documents and to take such further
actions as Triple-A One, the Surety Provider, the Program Manager, the
Collateral Agent or the Bank Collateral Agent may hereafter require.

                  (j) The terms of the Subordinated Note and the subordination
effected hereby, and the rights of Triple-A One, the Surety Provider, the
Program Manager, the Collateral Agent and the Bank Collateral Agent and the
obligations of the Seller and Finco arising hereunder, shall not be affected,
modified or impaired in any manner or to any extent by (a) any amendment or
modification of or supplement to any provision of the Operative Documents or any
instrument or document executed or delivered pursuant thereto or in connection

Commitment Termination Date.

                  Section 6.2. Remedies. (a) On the Commitment Termination
Date, all purchases by, and sales to, Finco of Contracts hereunder shall
immediately cease.

                  (a) On and after the Commitment Termination Date, Finco shall
have, in addition to all other rights under this Agreement, all rights and
remedies provided under any applicable law.

                  (b) On and after the Commitment Termination Date, Finco shall
continue to maintain its interest in all Purchased Contracts created prior to

                                   ARTICLE VII

                INDEMNIFICATION, ADDITIONAL COSTS AND INSPECTION

                  Section 7.1. Indemnities. (a) Without limiting any other
rights that Finco may have hereunder or under applicable law, the Seller hereby
agrees to indemnify Finco and its directors, employees, officers and successors
and assigns (collectively, the "Indemnified Parties") from and against any and
all damages, losses, claims, liabilities and related costs and expenses,
including all attorneys' fees and disbursements (all of the foregoing being

                                       24
<PAGE>   28

Purchased Contracts, excluding, however, recourse (except as otherwise
specifically provided in this Agreement) for uncollectible Purchased Contracts.
Without limiting the generality of the foregoing, the Seller shall indemnify the
Indemnified Parties for all Indemnified Amounts relating to or resulting from:

                  (i) the transfer of an ownership interest in any Contract
         other than an Eligible Contract;

                  (ii) reliance on any representation or warranty made by the
         Seller (or any of its Responsible Officers) or the Servicer (or any of
         its Responsible Officers), if the Seller or any Affiliate of the Seller
         is acting as the Servicer, under or in connection with the Operative
         Documents, and any information or report delivered by the Seller
         pursuant hereto, which shall have been false or incorrect in any
         material respect when made or deemed made;

                  (iii) the failure by the Seller to comply with any applicable
         law, rule or regulation with respect to any Purchased Contract or the
         nonconformity of any Purchased Contract with any such applicable law,
         rule or regulation;

                  (iv) the failure to vest and maintain vested in Finco or to
         transfer to Finco, legal and equitable title to and ownership of, an
         ownership interest in the Contracts that are, or are intended to be,
         Purchased Contracts, together with all proceeds thereof, including,
         without limitation, all Collections and other items that constitute
         proceeds, free and clear of any Lien whether existing at the time of
         the Purchase of such Contract or at any time thereafter;

                  (v) the failure to file, in a timely manner, financing
         statements or other similar instruments or documents required under the
         UCC in effect in the state in which the Seller's principal place of
         business is located or the location of the Collateral as required under
         such law or other applicable laws with respect to any Contracts sold to
         Finco, whether at the time of any Purchase or at any subsequent time;

                  (vi) any defense, setoff, counterclaim, recoupment or
         reduction of liability whatsoever under any Purchased Contract, arising
         out of a breach by the Seller of any obligation under such Purchased
         Contract or arising out of any other agreement, indebtedness or
         liability at any time owing to or in favor of any other Person from the
         Seller (it being understood that all such obligations of the Seller
         shall be and remain enforceable against and only against the Seller and
         shall not be enforceable against Finco);

                  (vii) any failure of the Seller to perform its duties or
         obligations in accordance with the provisions of this Agreement;

                  (viii) any products liability claim or personal injury or
         property damage suit or other similar or related claim or action of
         whatever sort arising out of or in 



                                       25
<PAGE>   29

         connection with merchandise or services which are the subject of any
         Purchased Contract or any Vehicle;

                  (ix) the failure by the Seller to pay when due any taxes
         payable by it, including without limitation, franchise taxes and sales,
         excise or personal property taxes payable in connection with the
         Contracts;

                  (x) the failure by the Seller or the Servicer (if the Servicer
         is the Seller or an Affiliate of the Seller) to be duly qualified to do
         business, to be in good standing or to have filed appropriate
         fictitious or assumed name registration documents in any jurisdiction;

                  (xi) the commingling of Collections at any time with other
         funds;

                  (xii) the failure of any Lock-Box Bank or the Clearing Account
         Bank to remit any amounts held in its Lock-Box or in the Clearing
         Account as the case may be pursuant to the instructions of the Servicer
         or the Collateral Agent, whether by reason of the exercise of setoff
         rights or otherwise; and

                  (xiii) any repayment by Finco which is required by law, or
         which Finco, Triple-A One or the Collateral Agent believes in good
         faith is required by law (as a preference or otherwise) of an amount
         that previously caused a reduction in principal amount of the Seller
         Note and any interest thereon required or believed in good faith by
         Finco, Triple-A One or the Collateral Agent to be required.

Notwithstanding the foregoing, Finco hereby agrees that under no circumstances
shall the Seller be liable for, or required to pay any Indemnified Amount, other
than as set forth in Section 4.5, resulting from, (i) the credit risk of an
Obligor, or for which payment therefor would otherwise constitute recourse to
the Seller for an uncollectible Contract or Contracts or (ii) gross negligence
or willful misconduct on the part of the Indemnified Party to which such
Indemnified Amount would otherwise be due.

                  (b) Any Indemnified Amount due hereunder shall be payable on
demand.

                  Section 7.2. Rights of Inspection. Finco and its
representatives and assigns, including without limitation the Program Manager
and the Surety Provider shall at all times have full and free access during
normal business hours (a) to the Seller's officers and independent accountants
in order to discuss the affairs, finances and accounts of the Seller insofar as
they relate to the Contracts, the Files and/or the Vehicles and the transactions
contemplated hereby and (b) to all the books, correspondence and records of the
Seller insofar as they relate to the Contracts, the Files and/or the Vehicles
and the transactions contemplated hereby, and Finco and its representatives and
assigns, including without limitation the Program Manager and the Surety
Provider may examine the same, take extracts therefrom and make photocopies
thereof, and the Seller agrees to render to Finco, and its representatives and
assigns, including without limitation the Program Manager and the Surety
Provider, at the Seller's sole cost and expense, such clerical and other
assistance as may be requested with regard thereto.

                                  ARTICLE VIII

                                  THE SERVICER

                  Section 8.1. Appointment of Servicer. Finco hereby appoints
the Seller to act as servicer of the Purchased Contracts in the name of and on
behalf of Finco in accordance with the provisions hereof and the Seller hereby
accepts such appointment. The Servicer shall use reasonable care in performing
its duties as servicer hereunder and, without limiting the foregoing, shall
service the Purchased Contracts in accordance with the Credit and Collection
Policy, attached hereto as Schedule 8.1.

                  Section 8.2.  Collections. (a) On each Business Day, all
Collections received in any Lock-Box shall be transferred to the Clearing
Account on such Business Day. All Collections received by the Servicer in any
other manner shall be transferred to the Clearing Account on the next Business
Day following receipt and until so transferred, the Servicer shall hold such
cash and other items in trust for the benefit of Finco. All Collections in the
Clearing Account shall be transferred to the Collection Account on the next
Business Day after such Collections are transferred into the Clearing Account.

                  (a) The Servicer will, at the Servicer's cost and expense and
as agent in the name of and on behalf of Finco, but subject at any time to the
right of Finco to direct and control, endeavor to collect, as and when the same
becomes due, all amounts owing on each Purchased Contract. In the event of
default by an Obligor under any Purchased Contract, the Servicer shall have the
power and authority, on behalf of Finco, to take such action in respect of such
Purchased Contract and the Vehicle related thereto as the Servicer, in the
absence of contrary instructions from Finco, may deem advisable, including the
power to sell such Purchased Contract. In the enforcement or collection of any
Purchased Contract, the Servicer shall be entitled to sue thereon in its own
name or as agent for Finco, in either case, for the account of Finco.

                  (b) In the event the Servicer accepts in payment of any
Purchased Contract the taking of repossession of the Vehicle, the Servicer
agrees to use its reasonable efforts to resell such Vehicle for the account of
Finco and shall remit to Finco the gross sale proceeds thereof, net of any costs
incurred by any Person with respect to any such repossession and resale. Finco
shall have no obligation to take any action or commence any proceedings to
realize upon any Purchased Contract or to enforce any of its rights or remedies
with respect thereto. Any moneys collected by the Servicer pursuant to this
subsection shall be segregated by the Servicer, held in trust by the Servicer
for Finco and shall be remitted to the Collection Account on the Business Day of
receipt thereof by the Servicer.

                  Section 8.3. Maintenance of Records; Quarterly and Annual
Reports. (a) The books of account and other records pertaining to the Purchased
Contracts are the property of Finco. Finco agrees that the Servicer shall hold
such records as Finco's agent. The Servicer shall maintain all books of account
and other records pertaining to the Purchased 



                                       27
<PAGE>   31

Contracts in such form as will enable Finco or the Program Manager or their
designees to determine at any time the status of the Purchased Contracts. The
Servicer will permit Finco or the Program Manager and any Person designated by
Finco or the Program Manager, during regular business hours, to inspect, audit,
check and make abstracts from all books, accounts, records, or other papers
pertaining to such Purchased Contracts. From time to time, at the request of
Finco or the Program Manager, the Servicer, at its own expense, will deliver to
Finco and the Program Manager and any Person designated by Finco or the Program
Manager any records and invoices pertaining to the Purchased Contracts and
evidence thereof as Finco or the Program Manager or such designee may deem
necessary to enable it to enforce its rights thereunder. In addition, at the
request of Finco or the Program Manager after delivery of a Servicer Termination
Notice, the Servicer will deliver all such records and invoices pertaining
thereto (including bills of lading) and other evidence thereof to any Person
selected by the Program Manager. Whether or not any such item is the property of
Finco, each computer record, invoice, ledger card, account record or other
evidence of, or record relating to, the Purchased Contracts maintained at the
office of the Servicer or the office of Seller, if requested by Finco or the
Program Manager, will be marked as the Program Manager may direct. Upon request
of the Program Manager, the Servicer will segregate from all other Contracts
then owned or being serviced by the Servicer all documents relating to the
Purchased Contracts and will hold in trust (if such document is not owned by
Finco) and safely keep such documents in separate filing cabinets or other
suitable containers marked to show Finco's interest with such legend as shall be
specified by the Program Manager and maintained in such place or places as shall
be designated by the Program Manager.

                  (a) The Servicer will deliver to Finco and the Program Manager
and any Person designated by the Program Manager, within 45 days after the end
of each fiscal quarter of the Servicer, a certificate of a Responsible Officer
of the Servicer stating that (a) a review of the activities of the Servicer
during the preceding fiscal quarter and of its performance under this Agreement
was made under the supervision of the officer signing such certificate and (b)
based on such review, the Servicer has fully performed all its obligations under
this Agreement throughout such period (including its obligations to prepare and
deliver each Investor Report, Daily Report and Monthly Report) in compliance
with the terms of this Agreement, or, if there has been a default in the
performance of any such obligation, specifying each such default known to such
officer and the nature and status thereof.

                  (b) The Servicer, at its expense, will cause a firm of
independent public accountants satisfactory to the Program Manager to furnish a
report (the "Annual Report") to Finco and the Program Manager and any Person
designated by the Program Manager, on or before March 31st of each year,
beginning on March 31, 1995, stating that such firm has examined certain
documents and records relating to the servicing of the Contracts during the
preceding fiscal year and that such examination, which has been conducted
substantially in accordance with audit guides or audit programs generally
recognized to be applicable to audits of receivables similar to the Contracts,
has disclosed no items of noncompliance with the provisions of this Agreement
throughout such period which, in the opinion of such firm, are material, except
for such items of non-compliance as shall be set forth in such report.

                  Section 8.4. Servicing Fee. On each Determination Date, to
the extent provided for in the Triple-A One Security Agreement, as full
compensation for its servicing activities hereunder, the Servicer shall be
entitled to receive the Servicing Fee.

                  Section 8.5. Resignation; Sub-Contracting. (a) The obligation
of the Servicer to service the Purchased Contracts is personal to the Servicer
and the parties recognize that another Person may not be qualified to perform
such obligations. Accordingly, the Servicer's obligation to service the
Purchased Contracts hereunder shall be specifically enforceable and shall be
absolute and unconditional in all circumstances, including, without limitation,
after the occurrence and during the continuation of any Servicer Termination
Event hereunder; provided, however, that a Successor Servicer may be appointed
pursuant to Section 8.12 hereof.

                  (a) The Servicer shall not resign from the obligations and
duties hereby imposed on it as Servicer except upon determination that (i) the
performance of its duties hereunder is no longer permissible under any
applicable law and (ii) there is no reasonable action which the Servicer could
take to make the performance of its duties hereunder permissible under any such
applicable law. Any determination permitting the resignation of the Servicer
shall be evidenced as to clause (i) above by an opinion of counsel to such
effect delivered to Finco and the Program Manager. Except to the extent
inconsistent with any such applicable law, no such resignation shall become
effective until a Successor Servicer shall have assumed the responsibilities and
obligations of the Servicer in accordance with Section 8.12 hereof.

                  (b) If the performance of its duties hereunder is no longer
permissible under applicable law or the cost of such performance is such that
its continuation as Servicer is not warranted as a financial matter, the
Servicer may, with the prior written consent of the Program Manager, subcontract
with any other Person to service, administer or collect the Purchased Contracts,
provided that the Person with whom the Servicer so subcontracts shall not become
the Servicer hereunder and the Servicer shall remain liable for the performance
of the duties and obligations of the Servicer pursuant to the terms hereof.

                  Section 8.6. Termination. The Servicer's obligations under
this Agreement shall terminate upon the termination of the Triple-A One Credit
Agreement; provided, however, that the Servicer shall continue to be obligated
to do all things necessary to apply Collections on the Purchased Contracts that
it receives after such termination in the manner provided in this Agreement and
to perform its obligations hereunder with respect thereto. Upon termination of
this Agreement all authority and power granted to the Servicer under this
Agreement shall pass to and be vested in Finco. The Servicer shall transfer (i)
its electronic records relating to the Purchased Contracts to Finco in such
electronic form as Finco may reasonably request, (ii) all other records,
correspondence and documents to Finco in the manner and at such times as Finco
may reasonably request, (iii) at Finco's expense, upon the request of Finco,
notify all Obligors that the Servicer is no longer the Servicer, (iv) at Finco's
expense, take all such further action as Finco shall reasonably request to
effect the termination of the rights of the Servicer to conduct servicing
hereunder, including, without limitation, the transfer to Finco of all authority
of the Servicer to (A) service Purchased Contracts as provided hereunder, and
(B) 



                                       29
<PAGE>   33

receive Collections which shall on the date of such termination be held by
the Servicer for deposit or which shall thereafter be received with respect to
any Purchased Contract.

                  Section 8.7. Delivery of Investor Report. On each
Determination Date, the Servicer shall deliver to Finco and the Program Manager,
no later than 9:00 A.M. (New York City time) on such Determination Date, a
report, substantially in the form of Exhibit F (the "Investor Report"), together
with a certificate, substantially in the form of Exhibit G (the "Servicer's
Certificate"), covering the Determination Period immediately preceding such
Determination Date.

                  Section 8.8. Daily Report. No later than 9:00 A.M. (New York
City time) on each Payment Date, the Servicer shall deliver a report,
substantially in the form of Exhibit H (the "Daily Report"), to Finco and the
Program Manager, together with a Servicer's Certificate.

                  Section 8.9. Monthly Report. No later than 9:00 A.M. (New
York City time) on each Determination Date, the Servicer shall deliver a report,
substantially in the form of Exhibit I (the "Monthly Report") to Finco and the
Program Manager, together with a Servicer's Certificate, covering the
Determination Period immediately preceding such Determination Date.

                  Section 8.10. Servicer Termination Events. If any of the
following events (each a "Servicer Termination Event") shall have occurred and
be continuing:

                  (a) the Servicer shall fail to make any payment, transfer or
deposit required to be made hereunder within two Business Days of the date on
which such payment, transfer or deposit is due to be made;

                  (b) the Servicer shall fail to give any notice within three
Business Days after the same is required to be given hereunder;

                  (c) the Servicer shall fail to submit (i) an Investor Report
or a Monthly Report within three Business Days of the day on which such report
shall have been required to be submitted, (ii) a Daily Report within one
Business Day of the day on which such report is required to be submitted or
(iii) an Annual Report within 10 days of the day on which such Annual Report
shall have been required to be submitted;

                  (d) the Servicer shall fail to observe or perform any other
covenant or agreement applicable to it contained herein and such failure shall
remain unremedied for a period of 10 days;

                  (e) the Servicer shall enter a corporate transaction in breach
of the covenant at Section 4.4(f) hereof;

                  (f) any representation, warranty, certification or statement
made by the Servicer in this Agreement or in any certificate, financial
statement or other document delivered pursuant to this Agreement shall prove to
have been incorrect in any material respect when made;



                                       30
<PAGE>   34
                  (g) a Bankruptcy Event shall have occurred with respect to the
Servicer;

                  (h) the Wind-Down Date shall have occurred;


then, the Program Manager may, in its discretion, terminate the Servicer by
giving five Business Days notice thereof in writing to the Servicer and Seller
which notice shall state the effective date of such termination (a "Servicer
Termination Notice"). On and after the effective date stated in a Servicer
Termination Notice, the Program Manager may, in its discretion, implement a
Complete Servicing Transfer.

                  Section 8.11. Servicer Termination. (a) After the Program
Manager gives the Servicer a Servicer Termination Notice, (i) prior to the
appointment of a Successor Servicer pursuant to Section 8.12, the Program
Manager may administer the administrative, servicing and collection functions of
the Servicer in any manner it deems fit, (ii) the Program Manager shall, at any
time thereafter, be entitled to notify the Obligors on any Purchased Contracts
to make payment of amounts due thereunder directly to Finco or the Program
Manager or as the Program Manager may direct and (iii) the Servicer shall, at
its own expense, (A) if so requested by the Program Manager, endorse each
instrument that is payable to the Servicer, if any, evidencing any Purchased
Contract to the Program Manager in such manner as the Program Manager shall
direct and (B) perform any and all acts and execute any and all documents as may
be reasonably requested by the Program Manager in order to effect the purposes
of this Agreement. After receipt by the Servicer of a Servicer Termination
Notice, if the Program Manager does not elect to replace the Servicer with a
Successor Servicer, the Program Manager shall have the right to appoint a firm
of public accountants or any other Person the Program Manager may choose, to
monitor the servicing of the Purchased Contracts by the Servicer and to furnish
to Finco, at the expense of the Servicer, such letters, certificates or reports
thereon as the Program Manager shall reasonably request. The Servicer shall
cooperate with such firm in the subsequent monitoring of its servicing of the
Purchased Contracts pursuant to this Agreement and any fees and expenses in
connection therewith shall be paid by the Servicer.

                  (a) After receipt by the Servicer of a Servicer Termination
Notice, if the Program Manager elects to appoint a Successor Servicer, then:

                           (i) On the date that a Successor Servicer shall have
         been appointed by the Program Manager pursuant to Section 8.12, all
         authority and power of the then Servicer under this Agreement shall
         pass to and be vested in such Successor Servicer, and, without
         limitation, the Program Manager is hereby authorized and empowered to
         execute and deliver on behalf of the Servicer, as attorney-in-fact or
         otherwise, all documents and other instruments upon the failure of the
         Servicer to execute or deliver such documents or instruments, and (upon
         the failure of the Servicer to cooperate) to do and accomplish all
         other acts or things necessary or appropriate to effect the purposes of
         such transfer of servicing rights.

                           (ii) The Servicer agrees to cooperate with the
         Program Manager and the Successor Servicer in effecting the termination
         of the responsibilities and rights of the Servicer to conduct servicing
         hereunder, including, without limitation, the transfer to 



                                       31
<PAGE>   35

         such Successor Servicer of all authority of the Servicer to service the
         Purchased Contracts provided for under this Agreement, including,
         without limitation, all authority to receive Collections which shall on
         the date of transfer be held by the Servicer for deposit, or which
         shall thereafter be received with respect to the Purchased Contracts.

                           (iii) The Servicer shall promptly transfer duplicate,
         back-up, or original tapes, and all other electronic media constituting
         all of its electronic records relating to the Purchased Contracts and
         records relating to the Commercial Paper Notes to the Successor
         Servicer in such electronic form as the Successor Servicer may
         reasonably request and shall promptly transfer to the Successor
         Servicer all other records, correspondence and documents necessary for
         the continued servicing of the Purchased Contracts in the manner and at
         such times as the Successor Servicer shall reasonably request.

                           (iv) At any time following the appointment of a
         Successor Servicer, such Successor Servicer shall be authorized to take
         any and all steps in the name of the previous Servicer and on behalf of
         the previous Servicer necessary or desirable, in the determination of
         such Successor Servicer, to collect all amounts due under any and all
         Purchased Contracts, including, without limitation endorsing the name
         of the previous Servicer on checks and other instruments representing
         Collections, and enforcing the Purchased Contracts.

                  Section 8.12. Appointment of Successor Servicer. (a) On and
after the receipt by the Servicer of a Servicer Termination Notice, the Servicer
shall continue to perform all servicing functions under this Agreement until the
later of (i) the appointment of a Successor Servicer or (ii) the date specified
in the Servicer Termination Notice or otherwise specified by the Program Manager
in writing or, if no such date is specified in the Servicer Termination Notice,
until a date mutually agreed upon by the Servicer and the Program Manager. The
Program Manager shall (as promptly as possible after the giving of a Servicer
Termination Notice) appoint a successor servicer (the "Successor Servicer") and
such Successor Servicer shall accept its appointment by a written assumption in
a form acceptable to the Program Manager.

                  (a) Upon its appointment, the Successor Servicer shall be the
successor in all respects to the Servicer with respect to servicing functions
under this Agreement and shall be subject to all the responsibilities, duties
and liabilities relating thereto placed on the Servicer by the terms and
provisions hereof, and all references in this Agreement to the Servicer shall be
deemed to refer to the Successor Servicer. Any Successor Servicer, by its
acceptance of its appointment, will automatically agree to be bound by the terms
and provisions of the Liquidity Agreement, if any are applicable. Any Successor
Servicer shall make all representations and warranties that the Servicer makes
hereunder.

                  (b) In connection with such appointment and assumption, the
Program Manager may, subject to the provisions of the Triple-A One Security
Agreement, make arrangements for the payment of the Servicing Fee to the
Successor Servicer.

                  Section 9.2. Successors and Assigns. This Agreement shall be
binding upon the parties hereto and their respective successors and assigns and
shall inure to the benefit of the parties hereto and their respective successors
and assigns; provided that the Seller shall not assign any of its rights or
obligations hereunder without the prior written consent of Finco and the Program
Manager. Except as expressly permitted hereunder or in the Operative Documents,
Finco shall not assign any of its rights or obligations hereunder without the
prior written consent of the Program Manager.

                  Section 9.3. Confirmation of Intent; Security Interest. The
parties hereto intend that the transfers to Finco by the Seller of Purchased
Contracts, all monies due or to become due with respect thereto and all
collateral security therefor, all proceeds of the foregoing, including, without
limitation, all Recoveries, as provided for herein be treated under applicable
state law and federal bankruptcy law, at all times and in each case, as absolute
and complete sales by the Seller to Finco; provided, however, that if for any
reason any such transfer is not considered a sale, the Seller hereby grants to
Finco a security interest in all such transferor's right, title and interest in
the Purchased Contracts and all other assets transferred to Finco pursuant to
Sections 2.1(a) and 2.1(b) hereof, as collateral security for the repayment by
the Seller of a loan in the amount of the aggregate Purchase Price paid to it.

provided for in Section 2.3(b) hereof, shall be made by 9:00 a.m. (New York City
time) on the day provided for herein. Amounts not paid when due under this
Agreement shall bear interest until paid in full at a rate equal at all times to
the lesser of (a) the Default Rate and (b) the maximum rate permitted by
applicable law, payable on demand. Whenever any payment to be made under this
Agreement shall be stated to be due on a day other than a Business Day, such
payment shall be made on the next succeeding Business Day.

                  Section 9.5. Rights to Enable Successor Servicing. For the
purpose of enabling Finco or a Successor Servicer to perform the functions of
servicing and collecting the Purchased Contracts upon a Complete Servicing
Transfer, the Servicer shall on or prior to the Closing Date execute and deliver
the On-Line Service Agreement, as set forth on Schedule 9.5. The Servicer hereby
represents and warrants to Finco that such On-Line Service Agreement embodies
all rights and properties necessary or appropriate for the servicing and
collecting functions with respect to Purchased Contracts and hereby covenants
that to the extent Finco or the Collateral Agent deem it necessary or
appropriate, it will immediately transfer, assign and set 



                                       34
<PAGE>   38

over to Finco, the Collateral Agent or such party as the Collateral Agent shall
designate any other rights or assets upon the occurrence of a Wind-Down Event to
enable and ease successor servicing hereunder.

                  Section 9.6. Costs; Expenses and Taxes. In addition to the
rights of indemnification granted pursuant to Section 7.1 hereof, the Seller
agrees to pay on demand to Finco (a) all costs and expenses in connection with
the development, preparation, execution, delivery and administration (including
periodic auditing by Finco or its agents or representatives) of this Agreement,
and the other Operative Documents, including, without limitation, the reasonable
fees and expenses of counsel for any Indemnified Party with respect hereto and
with respect to advising any such Indemnified Party as to their respective
rights and remedies under this Agreement, and (b) all costs and expenses, if any
(including reasonable counsel fees and expenses), in connection with the
enforcement of this Agreement, and the other Operative Documents.

                  Section 9.7. Severability Clause. Any provisions of this
Agreement which are prohibited 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, and any
such prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provisions in any other jurisdiction.

                  Section 9.8. Amendments; Governing Law; JURY TRIAL WAIVER.
This Agreement and the rights (including those of the Program Manager and the
Collateral Agent) and obligations of the parties hereunder (a) may not be
changed orally but only by an instrument in writing signed by the party against
which enforcement is sought and (b) shall be construed in accordance with and
governed by the laws of the State of New York. No amendment shall be effective
without prior written notice thereof to S&P and Moody's. EACH PARTY HERETO
HEREBY IRREVOCABLY WAIVES ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION OR
PROCEEDING (ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OF THE
TRANSACTIONS CONTEMPLATED HEREBY OR BY ANY OF THE OTHER OPERATIVE DOCUMENTS) IN
WHICH THEY SHALL BE ADVERSE PARTIES.

                  Section 9.9. No Recourse. Except as otherwise expressly
provided in Section 4.5 and 7.1 of this Agreement, it is understood and agreed
that the Seller shall not be liable for the payment of the principal of the
Loans, or any Commercial Paper or for the payment of any business taxes or for
any losses suffered by Finco in respect of ownership of the Purchased Contracts.
The preceding sentence shall not relieve the Seller from any liability hereunder
with respect to its representations, warranties, covenants and other payment and
performance obligations herein described. The Seller is not making any
representations or warranties regarding the collectibility of the Purchased
Contracts or the future performance of the Obligors under the Purchased
Contracts.

                  Section 9.10. Further Assurances. The Seller agrees to do
such further acts and things and to execute and deliver to Finco such
assignments, agreements, powers and

effect the purposes of this Agreement and the other Operative Documents or to
better assure and confirm unto Finco its rights, powers and remedies hereunder

record, notify, obtain consents and file and to re-record, re-notify, re-obtain
consents and re-file all such documents and instruments, at such time or times,
in such manner and at such places, all as may be necessary to preserve and
protect the position of the Seller or Finco, as the case may be, hereunder and
under the other Operative Documents. This covenant shall survive the termination
of this Agreement.

                  Section 9.11. Termination. This Agreement shall terminate on
the later of (a) the date after the Commitment Termination Date of the payment
in full of all amounts due hereunder and the performance of all obligations
hereunder and (b) the date on which the Triple-A One Credit Agreement is
terminated; provided, however, that all representations, warranties, remedies
and indemnities of the Seller herein, and the agreements of the Seller made
pursuant to Section 9.15 hereof shall survive the termination of this Agreement.

                  Section 9.12. Assignment to Program Manager. Finco hereby
assigns to the Program Manager, all of its rights hereunder, including, without
limitation, the rights of Finco under Section 6.2. The Seller consents to such
assignment and agrees that the Program Manager shall be entitled to enforce this
Agreement directly against the Seller. In addition, Finco agrees to act as agent
on behalf of the Program Manager and shall not consent or agree to any waiver,
amendment or other modification of this Agreement or any of the other Operative
Documents to which it is a party without the Program Manager's prior written
consent, and shall take and refrain from taking any action, and shall exercise
and refrain from exercising any of its rights under the Operative Documents as
requested by the Program Manager from time to time, including, without
limitation, the right to deliver a Servicer Termination Notice.

                  Section 9.13. Counterparts. This Agreement may be executed in
any number of counterparts, and by the different parties hereto on the same or
separate counterparts, each of which shall be deemed to be an original
instrument.

                  Section 9.14. Headings. Section headings used in this
Agreement are for convenience of reference only and shall not affect the
construction or interpretation of this Agreement.

                  Section 9.15. No Bankruptcy Petition Against Finco. The Seller
covenants and agrees that prior to the date which is one year and one day after
the payment in full of all Commercial Paper issued by, and all Triple-A One

                                   SELLER NOTE

                                                              New York, New York
                                                              September 12, 1994


                  ONYX ACCEPTANCE FINANCIAL CORPORATION, a Delaware corporation
("Finco"), hereby promises to pay to the order of ONYX ACCEPTANCE CORPORATION, a
California corporation (the "Seller"), the principal amount of this Seller Note,
determined as described below, together with interest thereon equal to the
Seller Note Interest Rate in lawful money of the United States of America.
Capitalized terms used herein but not defined herein shall have the meanings
assigned to such terms in the Definitions List, dated as of the date hereof,
entered into in connection with the Sale and Servicing Agreement, dated as of
September 8, 1994, between the Seller and Finco (such agreement, as it may from
time to time be amended, supplemented or otherwise modified in accordance with
its terms, the "Sale Agreement").

                  The principal amount of this Seller Note at any time shall be
determined in accordance with the provisions of Section 5.1 of the Sale
Agreement. All principal and accrued interest on this Seller Note shall be due
and payable on the Scheduled Maturity Date; provided, however, that, no payments
may be made, directly or indirectly, on this Seller Note (and if made, the
Seller agrees to return such payments to Finco) until Finco has paid all amounts
required pursuant to the Triple-A One Security Agreement to be paid prior to any
payments in respect of this Seller Note. This Seller Note represents solely an
obligation of Finco to make certain payments from funds available under the
Triple-A One Security Agreement and only to the extent, in the manner and at the
times set forth in the Triple-A One Security Agreement. This Seller Note does
not represent a security interest in the Collateral.

                  Payments of principal of and interest on this Seller Note
shall be made by wire transfer of immediately available funds to such account of
the Seller as the Seller may designate in writing.

                  This Seller Note is the Seller Note referred to in the Sale
Agreement.

                  Finco hereby waives diligence, presentment, demand, protest
and notice of any kind whatsoever. The nonexercise by the holder of any of its
rights hereunder in any particular instance shall not constitute a waiver
thereof in that or any subsequent instance.

                  All amounts evidenced by this Seller Note and all payments and
prepayments of the principal hereof and the respective dates and maturity dates
thereof shall be endorsed by the holder hereof on Schedule 1 attached hereto and
made a part hereof or on a continuation thereof which shall be attached hereto
and made a part hereof, or otherwise recorded by such holder in its internal
records; provided, however, that the failure of the holder hereof to make such a



<PAGE>   42

notation or any error in such a notation shall not affect the obligations of
Finco under this Seller Note.

                  It is the intention of Finco and the Seller to conform
strictly to applicable usury laws. Accordingly, if the transactions contemplated
hereby would be usurious under applicable law (including the laws of the State
of New York and the laws of the United States of America), then, in that event,
notwithstanding anything to the contrary in any agreement entered into in
connection with this Seller Note, it is agreed as follows: (i) the aggregate of
all consideration that constitutes interest under applicable law that is taken,
reserved, contracted for, charged or received under this Seller Note or any
other agreement or document executed in connection with this Seller Note shall
under no circumstances exceed the maximum amount of interest allowed by
applicable law, and any excess shall be credited to other amounts due under this
Seller Note by the holder hereof (or if this Seller Note shall have been paid in
full, refunded to Finco); and (ii) in the event that the maturity of this Seller
Note is accelerated for any reason or in the event of any required or permitted
prepayment, then such consideration that constitutes interest may never include
more than the maximum amount allowed by applicable law, and excess interest, if
any, provided for in this Seller Note or otherwise shall be canceled
automatically as of the date of such acceleration or prepayment and, if
theretofore prepaid, shall be credited to other amounts due under this Seller
Note (or if this Seller Note shall have been paid in full, refunded to Finco).
In the event that applicable law provides for a ceiling on the rate of interest
chargeable hereunder, that ceiling shall be the indicated rate ceiling.

                  The Seller agrees that it shall have no right to cause, by way
of acceleration or otherwise, any payment of principal hereunder to become due
or payable prior to the times provided in the Triple-A One Security Agreement.

                  Each holder of this Seller Note agrees to be bound by all of
the provisions of the Operative Documents, including, without limitation, the
covenant that prior to the date which is one year and one day after the payment
in full of all Commercial Paper issued, and all Triple-A One Loans made, by
Triple-A One and all other obligations under the Operative Documents, it will
not institute, or join any other Person in instituting, against Finco any
bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings
or other similar proceedings under any federal or state bankruptcy law or
similar law.

                  This Seller Note may not be assigned, transferred, exchanged,
pledged, hypothecated, participated or otherwise conveyed, except with the prior
written consent of the Program Manager.

BOUND BY ALL THE PROVISIONS OF ARTICLE V OF THE SALE AND SERVICING AGREEMENT.


                                                              New York, New York
                                                              September 12, 1994

                  ONYX ACCEPTANCE FINANCIAL CORPORATION, a Delaware corporation
("Finco"), hereby promises to pay to the order of ONYX ACCEPTANCE CORPORATION, a
California corporation (the "Seller"), the principal amount of this Subordinated
Note, determined as described below, together with interest thereon at a rate
per annum of LIBOR + 6% in lawful money of the United States of America.
Capitalized terms used herein but not defined herein shall have the meanings
assigned to such terms in the Definitions List attached to the Sale and
Servicing Agreement dated as of September 8, 1994, between Finco and the Seller
(such agreement, as it may from time to time be amended, supplemented or
otherwise modified in accordance with its terms, the "Sale Agreement").

                  The principal amount of this Subordinated Note at any time
shall be determined in accordance with the provisions of Section 5.3 of the Sale
Agreement. All principal of and interest on this Subordinated Note shall be due
and payable at the times provided in the Sale Agreement, it being understood and
agreed that, except as provided in Section 5.3 of the Sale Agreement, no
payments may be made, directly or indirectly, on this Subordinated Note until
all the Obligations have been indefeasibly paid in full in cash. This
Subordinated Note is secured by the Collateral pursuant to the Subordinated
Security Agreement subject to the prior lien of the Collateral Agent under the
Triple-A One Security Agreement. No payments may be received, directly or
indirectly, by the Seller (and if received, the Seller agrees to return such
payments to Finco) on this Subordinated Note unless Finco has paid all amounts
required pursuant to the 


<PAGE>   46
Triple-A One Security Agreement to be paid prior to any payment in respect of
this Subordinated Note.

                  Payments of principal on this Subordinated Note shall be made
by wire transfer of immediately available funds to such account of the Seller as
the Seller may designate in writing.

                  This Subordinated Note is the Subordinated Note referred to in
the Sale Agreement, and is subordinate and junior in right of payment to all the
Obligations to the extent and in the manner provided in Section 5.3 of the Sale
Agreement and the holder by acceptance hereof agrees to be bound by all the
provisions of Section 5.3 of the Sale Agreement.

                  Finco hereby waives diligence, presentment, demand, protest
and notice of any kind whatsoever. The nonexercise by the holder of any of its
rights hereunder in any particular instance shall not constitute a waiver
thereof in that or any subsequent instance.

                  All amounts evidenced by this Subordinated Note and all
payments and prepayments of the principal hereof and the respective dates and
maturity dates thereof shall be endorsed by the holder hereof on Schedule 1
attached hereto and made a part hereof or on a continuation thereof which shall
be attached hereto and made a part hereof, or otherwise recorded by such holder
in its internal records; provided, however, that the failure of the holder
hereof to make such a notation or any error in such a notation shall not affect
the obligations of Finco under this Subordinated Note.

                  It is the intention of Finco and the Seller to conform
strictly to applicable usury laws. Accordingly, if the transactions contemplated
hereby would be usurious under applicable law (including the laws of the State
of New York and the laws of the United States of America), then, in that event,
notwithstanding anything to the contrary in any agreement entered into in
connection with this Subordinated Note, it is agreed as follows: (i) the
aggregate of all consideration that constitutes interest, if any, under
applicable law that is taken, reserved, contracted for, charged or received
under this Subordinated Note or any other agreement or document executed in
connection with this Subordinated Note shall under no circumstances exceed the
maximum amount of interest allowed by applicable law, and any excess shall be
credited to other amounts due under this Subordinated Note by the holder hereof
(or if this Subordinated Note shall have been paid in full, refunded to Finco);
and (ii) in the event that maturity of this Subordinated Note is accelerated for
any reason, or in the event of any required or permitted prepayment, then such
consideration that constitutes interest may never include more than the maximum
amount allowed by applicable law, and excess interest, if any, provided for in
this Subordinated Note or otherwise shall be cancelled automatically as of the
date of such acceleration or prepayment and, if theretofore prepaid, shall be
credited to other amounts due under this Subordinated Note (or if this
Subordinated Note shall have been paid in full, refunded to Finco). In the event
that applicable law provides for a ceiling on the rate of interest, if any,
chargeable hereunder, that ceiling shall be the indicated rate ceiling.

<PAGE>   47

                  The Seller agrees that it shall have no right to cause, by way
of acceleration or otherwise, any payment of principal hereunder to become due
or payable, prior to the times provided in the Triple-A One Security Agreement.

                  Each holder of this Note agrees to be bound by all of the
provisions of the Operative Documents, including, without limitation, the
covenant that prior to the date which is one year and one day after the payment
in full of all Commercial Paper issued, and all Triple-A One Loans made, by
Triple-A One and all other Obligations under the Operative Documents, it will
not institute against, or join any other Person in instituting against, Finco
any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceedings or other similar proceeding under the law of the United States or
any state of the United States.

                  This Subordinated Note shall not be assigned, transferred,
exchanged, pledged, hypothecated, participated or otherwise conveyed, except
with the prior written consent of the Program Manager.
