ASSIGNMENT; INTENT OF THE PARTIES; SECURITY INTEREST.

        Seller  hereby assigns and transfers to Buyer, for good and valuable

                acknowledged by Seller, the Eligible Assets subject to each
                Transaction including, without limitation, the Contracts
                relating to the Purchased Auto Loans that are subject to each
                Transaction.

        In the event, for any reason, any Transaction is construed by any
                court as a secured loan rather than a purchase and sale, the
                parties intend that Seller shall have granted to Buyer, and the
                Seller hereby does grant to Buyer, all right title and interest
                of Seller in and to, and a lien upon and a continuing and
                security interest in, all of Seller's right title and interest
                to the Eligible Assets, all rights with respect thereto and all
                proceeds thereof.

        Seller  shall pay all fees and expenses associated with perfecting such
                security interest including, without limitation, the cost of
                filing financing statements under the Uniform Commercial Code.

        In the event that Buyer elects to engage in repurchase transactions
                with the Eligible Assets or otherwise elects to pledge or
                hypothecate such Eligible Assets, Seller shall, at the request
                of Buyer and at the expense of Seller, provide Buyer's
                counterparty in such repurchase transaction with an opinion of
                counsel to the effect that such counterparty has a perfected
                first priority security interest in the Eligible Assets.

        Notwithstanding Paragraph 9(b) of the Repurchase Agreement, it is the
                intention of the parties that the Custodian, rather than Seller,
                shall maintain custody of the Purchased Securities pursuant to
                the Custody Agreement.

REPRESENTATIONS, WARRANTIES AND COVENANTS.

        Each party represents and warrants, and shall on and as of the
                Purchase Date of any Transaction be deemed to represent and
                warrant, as follows:

                The execution, delivery and performance of the Agreement and
                        the performance of each Transaction do not and will not
                        result in or require the creation of any lien, security
                        interest or other charge or encumbrance (other than
                        pursuant to the Agreement) upon or with respect to any
                        of its properties; and

        The Agreement is, and each Transaction when entered into under the
                Agreement will be, a legal, valid and binding obligation of it
                enforceable against it in accordance with the terms of the
                Agreement.

        Seller represents and warrants to Buyer, and shall on and as of the
                Purchase Date of any Transaction be deemed to represent and
                warrant, as follows:

                through affiliates and no director or officer of Seller is also

        None of the Purchase Price for any Eligible Assets will be used either

                defined in Regulation T of the Regulations of the Board of
                Governors of the Federal Reserve System, and Seller has not
                taken any action that might cause any Transaction to violate any
                regulation of the Federal Reserve Board;

        Each Auto Loan conforms to the current market standards of
                institutional securitization applicable to auto loans similar in
                nature to the Auto Loans;

        Each Auto Loan was underwritten in accordance with the written
                underwriting standards of Seller's Origination Guidelines
                furnished by Seller to Buyer, and no change to such underwriting
                standards has occurred since the date of the last written
                revision to such standards was furnished to Buyer by Seller or
                on behalf of Seller;

                Onyx;

        Seller shall be at the time it delivers any Eligible Assets for any
                Transaction, and shall continue to be, through the Purchase Date
                relating to each such Transaction, the legal and beneficial
                owner of such Eligible Assets, free of any lien, security
                interest, option or encumbrance except for the security interest
                created by or pursuant to the Agreement;

        Seller has taken all action with respect to the Agreement, the Custody
                Agreement and the transactions contemplated hereby and thereby
                in order to comply with the provisions of all applicable law;

        There exists for each Eligible Asset, other than Contracts originated
                by a Seller's Affiliate, a fully executed Dealer Agreement in
                the form of Exhibit F hereto;

        The Affiliate Purchase Agreement has been duly authorized, executed and
                delivered by the parties thereto and constitutes a valid and
                binding agreement of the parties thereto, enforceable in
                accordance with its terms; and

        Buyer is a third party beneficiary to the Affiliate Purchase Agreement
                and is entitled to enforce the rights of Seller thereunder.

        Seller covenants with Buyer, from and after the date of the Agreement,
                as follows:

        Seller will take all actions necessary with respect to the Agreement,
                the Custody Agreement and the transactions contemplated hereby
                and thereby in order to maintain compliance with the provisions
                of all applicable law;

        Seller shall immediately notify Buyer if an Event of Default or an
                event contemplated by Paragraph 9 of these Supplemental Terms
                shall have occurred;

        Seller shall deliver a Computer Tape relating to the Custody Agreement

                event less frequently than bi-monthly;

        Seller shall deliver to Buyer a Weekly Report on the first business day
                of each week during the term of the Agreement;

        Seller shall cause Onyx to deliver to Buyer, in writing within thirty
                (30) days after the end of each calendar quarter, a certificate
                of an authorized officer to the effect that the events
                contemplated by Paragraph 8(a)(viii) have not occurred; and

        Seller shall proceed in good faith to cause Onyx amend Onyx's existing
                warehouse agreements so as to enable Onyx to provide to Buyer a
                guaranty substantially in the form of Exhibit D hereto, and
                after such amendments have been made Seller shall cause Onyx to
                provide such guaranty to Buyer.

EVENTS OF DEFAULT.

        The term "Event of Default" shall, in addition to the definition set
                forth in the Repurchase Agreement, include the following events:

        Any governmental or self-regulatory authority shall take possession
                of Buyer or Seller or Onyx or their property or appoint any

        Buyer shall have reasonably determined that Seller (or, when the
                Guarantee is provided, Onyx) is or will be unable to meet its
                commitments under the Agreement (or, in the case of Onyx, the
                Guarantee), shall have notified Seller (or Onyx, as and when
                applicable) of such determination and such party shall not have
                responded with appropriate information to the contrary to the
                satisfaction of Buyer within 24 hours.

        The Agreement shall for any reason cease to create a valid, first
                priority security interest in any of the Eligible Assets
                purported to be covered thereby.

        A final judgment by any competent court in the United States of
                America for the payment of money in an amount of at least
                $100,000 is rendered against Seller or Onyx, and the same
                remains undischarged for a period of sixty (60) days during
                which execution of such judgment is not effectively stayed.

                time or both shall constitute an event of default shall occur
                and be continuing under any repurchase or other financing
                agreement for borrowed funds or indenture for borrowed funds by
                which Seller or Onyx is bound or affected shall occur and be
                continuing including, without limitation, any such agreement of
                Seller or Onyx to which Buyer or any of its affiliates is a
                party.

        Onyx shall experience losses or changes in its financial condition
                (exclusive of amounts withdrawn for payment of taxes due and

                for any two consecutive calendar quarters to be less than or
                equal to 80% of its Net Worth as of the commencement of such
                period.

                of the end of each calendar month shall exceed 8:1.

        Onyx's Net Worth shall at any time be less than $30,000,000.

        Upon the occurrence and during the continuance of an Event of Default by
                Seller:

                authorized to receive pursuant to Paragraph 5 of these
                Supplemental Terms shall cease, and all such rights shall
                thereupon become vested in Buyer, which shall thereupon have the
                sole right to receive such payments and apply them to the
                aggregate unpaid Repurchase Prices owed by Seller.

        All payments which are received by Seller contrary to the provisions
                of the preceding clause (i) shall be received in trust for the
                benefit of Buyer and shall be segregated from other funds of
                Seller.

        Buyer may, in its sole discretion upon the occurrence and during the
                continuation of an Event of Default hereunder, proceed against
                any assets held by it under any agreement between Buyer or any
                of its affiliates and Seller (including, without limitation, the
                Master Assignment Agreement) and shall have a right of set-off

                agreement between Buyer or any of its affiliates and Seller or
                any of its affiliates (including, without limitation, the Master
                Assignment Agreement), proceed against any assets held by it

                        occurred in the business, operations, properties,
                        prospects or condition (financial or otherwise) of
                        Seller or Onyx;

        Buyer shall request written assurances as to the financial well-being

                default could materially adversely affect the financial
                condition of such party (which covenants include, but are not
                limited to, an Act of Insolvency of Seller or Onyx or the
                failure of Seller or Onyx to 


                                       12

                gradations within such generic grades) by any nationally
                recognized statistical rating organization;

        Any representation or warranty made by Seller in the Agreement or any 
                Custody Agreement shall have been incorrect or untrue when made
                or repeated or when deemed to have been made or repeated;

        Seller shall fail to promptly notify Buyer of (i) the acceleration of

        The events specified in Paragraph 9(a) of these Supplemental Terms

                Repurchase Date for a Transaction shall be in addition to any
                other rights of Buyer to cause such an acceleration under the
                Agreement.

                Seller shall cause the Eligible Assets to continue to be
                serviced for the benefit of Buyer and, if Buyer shall exercise
                its rights to sell the Eligible Assets pursuant to the Agreement

        Seller shall cause the Eligible Assets to be serviced in accordance
                with the servicing standards for similar assets employed by
                prudent servicers in the auto loan industry for similar assets.

        Seller shall cause the Servicer to enforce the rights of the owner of
                the Eligible Assets in accordance with the standards of a
                prudent lender in the auto loan industry.


                                       16
<PAGE>   17
        Buyer may, in its sole discretion if an Event of Default shall have
                occurred and be continuing, without payment of any termination
                fee, servicing fee or any other amount to Seller, Onyx or any
                Servicer, (i) sell its right to the Eligible Assets on a
                servicing released basis or (ii) terminate the Servicer of the
                Eligible Assets with or without cause.

        Each Servicer of Eligible Assets must be approved by Buyer.

        FURTHER ASSURANCES. Seller shall promptly provide such further
                assurances or agreements as Buyer may request in order to effect
                the purposes of the Agreement.

        BUYER AS ATTORNEY-IN-FACT. Buyer is hereby appointed to act after the
                occurrence and during the continuation of an Event of Default as
                the attorney-in-fact of Seller for the purpose of carrying out
                the provisions of the Agreement and taking any action and
                executing any instruments that Buyer may deem necessary or
                advisable to accomplish the purposes hereof, which appointment
                as attorney-in-fact is irrevocable and coupled with an interest.
                Without limiting the generality of the foregoing, Buyer shall
                have the right and power after the occurrence and during the
                continuation of any Event of Default to receive, endorse and
                collect all checks made payable to the order of Seller
                representing any payment on account of the principal of or
                interest on any of the Purchased Securities and to give full
                discharge for the same.

        TERMINATION. Notwithstanding any provisions of Paragraph 15 of the
                Master Repurchase Agreement to the contrary, the Agreement and
                all Transactions outstanding hereunder shall terminate
                automatically without any requirement for notice on the date
                occurring eleven calendar months and twenty-nine days after the
                date as of which the Agreement is entered into; provided,
                however, that the Agreement and any Transaction outstanding
                hereunder may be extended by mutual agreement of Buyer and
                Seller; and provided further, however, that no such party shall
                be obligated to agree to such an extension.

                agreements in the Agreement shall bind the successors and
                assigns of the parties hereto, whether expressed or not.

        NOTICES AND OTHER COMMUNICATIONS. Any provision of Paragraph 13 of the
                Repurchase Agreement to the contrary notwithstanding, any notice

                     OPINIONS OF COUNSEL TO SELLER AND Onyx

     [Opinions regarding the Guarantee shall be provided after the Guarantee
                                  is issued.]


Seller is a corporation duly incorporated, validly existing and in good
        standing under the laws of the State of Delaware and has the corporate
        power and authority to execute, deliver and perform its obligations
        under the Agreement and the Custody Agreement. Seller is duly qualified
        to do business and is in good standing in each jurisdiction in which the
        character of the business transacted by it requires such qualification
        and in which the failure so to qualify would have a material adverse
        effect on the business, properties, assets or condition (financial or
        other) of Seller and its subsidiaries, considered as a whole.

Onyx is a corporation duly incorporated and validly existing and in good
        standing under the laws of the State of Delaware and has the corporate
        power and authority to execute, deliver and perform its obligations
        under the Guarantee. Onyx is duly qualified to do business and is in
        good standing in each jurisdiction in which the character of the
        business transacted by it requires such qualification and in which the
        failure so to qualify would have a material adverse effect on the
        business, properties, assets or condition (financial or other) of Onyx
        and its subsidiaries, considered as a whole.

The execution, delivery and performance by Seller of the Agreement and the
        Custody Agreement (a) has been duly authorized by all necessary
        corporate action on the part of Seller, (b) does not and will not
        violate, or result in a breach of (1) the Certificate of Incorporation
        or Bylaws of Seller, (2) the provisions of the Delaware General
        Corporate Law or any California, New York or federal law, rule or
        regulation applicable to Seller (other than California, New York and
        federal securities laws, as to which no opinion is expressed) or (3) to
        the best of counsel's knowledge, any order of any court or other
        governmental authority to which Seller is a party or by which Seller or
        any of its properties are bound or subject, where, in the case of items
        (2) and (3), such violation or breach could have a material and adverse
        effect on the ability of Seller to perform its obligations under the
        Agreement or the Custody Agreement and (c) will not conflict 


                                     A-1-1
<PAGE>   20
        with, or result in a breach, violation or acceleration of, or constitute
        a default under any material agreement to which Seller is a party or by
        which Seller is bound.

The execution, delivery and performance by Onyx of the Guaranty (a) has been
        duly authorized by all necessary corporate action on the part of Onyx,
        (b) does not and will not violate, or result in a breach of (1) the
        Certificate of Incorporation or Bylaws of Onyx, (2) the provisions of
        the Delaware General Corporation Law, or any California, New York or
        federal law, rule or regulation applicable to Onyx (other than
        California, New York and federal securities laws, as to which counsel
        expresses no opinion) or (3) to the best of counsel's knowledge, any
        order of any court or other governmental authority to which Onyx is a
        party or by which Onyx or any of its properties are bound or subject,
        where in the case of items (2) and (3) above, such violation or breach
        could have a material and adverse effect on the ability of Onyx to
        perform its obligations under the Guaranty and (d) will not conflict
        with, or result in a breach, violation or acceleration of, or constitute
        a default under any of the material agreements to which Onyx is a party
        or by which it is bound.

Each of the Agreement and the Custody Agreement has been duly executed and
        delivered by Seller and constitutes the legal, valid and binding
        obligation of Seller enforceable against Seller in accordance with its
        terms.

No authorization, consent approval, license, filing or registration with any 
        governmental or regulatory authority or agency is required under
        California, New York or federal law for the validity of the execution
        and delivery of, or performance by Seller of its obligations under the
        Agreement and the Custody Agreement (except (a) such as have been
        received or made, (b) such as may be required under California, New York
        or federal securities laws, as to which no opinion is expressed, and (c)
        such filings of financing or continuation statements as may be required
        to be made under the Uniform Commercial Code in any jurisdiction).

The Guaranty has been duly executed and delivered by Onyx and constitutes the 
        legal, valid and binding obligation of Onyx enforceable against Onyx in
        accordance with its terms.


                                     A-1-2
<PAGE>   21
To the best of counsel's knowledge, there is no action, suit, proceeding or
        investigation before or by any court or governmental agency or body,
        domestic or foreign, now pending or threatened against Seller which
        could reasonably be expected to interfere with or materially and
        adversely affect the consummation of the transactions contemplated in
        the Agreement or the Custody Agreement.

To the best of counsel's knowledge, there is no action, suit, proceeding or
        investigation before or by any court or governmental agency or body,
        domestic or foreign, now pending or threatened against Onyx which could
        reasonably be expected to interfere with or materially and adversely
        affect the consummation of the transactions contemplated in the
        Guaranty.

Assuming this Agreement does not transfer an ownership interest in a Purchased
        Auto Loan, the Agreement creates in favor of Buyer a security interest
        under the Uniform Commercial Code as currently in effect in the State of
        New York. Upon delivery of a List of Auto Loans as required by the
        Custody Agreement, the conveyance from time to time of Auto Loans
        described on such List of Auto Loans by Seller to the Custodian, on
        behalf of Buyer, in the State of California will perfect the security
        interest in favor of Buyer under the Uniform Commercial Code as
        currently in effect in the State of California (the "California UCC")
        and, assuming Buyer acquires its security interest in such Purchased
        Auto Loan in the ordinary course of its business and that Buyer acts
        without knowledge that the specific Purchased Auto Loan is subject to a
        security interest (other than the security interest in favor of Buyer),
        such security interest of Buyer will be prior to any security interest
        which may be perfected under Article 9 of the California UCC.

                         REPRESENTATIONS AND WARRANTIES

        Characteristics of Eligible Assets. Each Eligible Asset (A) was fully
and properly executed by the parties thereto, (B) contains customary and
enforceable provisions such as to render the rights and remedies of the holder
thereof adequate for realization against the collateral security, (C) is fully
amortizing and provides for level monthly payments which, if made when due,
shall fully amortize the amount financed over the original term and (D) provides
for, in the event that such Eligible Asset is prepaid in full, payment of an
amount that fully pays the principal balance and includes accrued but unpaid
interest at least through the date of prepayment in an amount at least equal to
its annual percentage rate. If such Eligible Asset was originated by a dealer,
such Eligible Asset, to the knowledge of Seller, was originated by the dealer
for the retail sale of a Financed Vehicle in the ordinary course of such
dealer's business, was purchased by Seller from such dealer for new value under
a Dealer Agreement and was validly assigned by the dealer to Seller. To the
knowledge of Seller, such dealer had all necessary licenses and permits to
originate Eligible Assets in the state where such dealer was located. If such
Eligible Asset was originated by an affiliate of Seller, such Eligible Asset was
originated for value by such affiliate in the ordinary course of its business to
finance the purchase of, or refinance, the related Financed Vehicle by the
related Obligor. Such affiliate of Seller had all necessary licenses and permits
to originate or purchase such Eligible Asset. Either the Eligible Assets
constitute substantially all of the motor vehicle receivables owned by Seller or
no adverse selection procedure was used in selecting the Eligible Assets from
among the motor vehicle receivables owned by Seller.

        No Fraud or Misrepresentation. Each Eligible Asset was originated by a
dealer or an affiliate of Seller and was sold by the dealer to Seller (if
applicable) without any fraud or misrepresentation on the part of such dealer.

        Compliance with Law. To the knowledge of Seller, all requirements of
applicable federal, state and local laws, and regulations thereunder (including,
without limitation, usury laws, the Federal Truth-in-Lending Act, the Equal
Credit Opportunity Act, the Fair Credit Billing Act, the Fair Credit Reporting
Act, the Fair Debt Collection Practices Act, the Federal Trade Commission Act,
the Magnuson-Moss Warranty Act, the Federal Reserve Board's Regulations "B" and
"Z", the Soldiers' and Sailors' Civil Relief Act of 1940, the state motor
vehicle

retail installment sales act, and state adaptations of the National Consumer Act
and of the Uniform Consumer Credit Code and other consumer credit laws and equal
credit opportunity and disclosure laws) in respect of all of the Eligible Assets
and each and every sale of Financed Vehicles, have been complied with in all
material respects, and each Eligible Asset and the sale of the Financed Vehicle
evidenced by each Eligible Asset complied at the time it was originated or made
and now complies in all material respects with all applicable legal
requirements.

        Origination. Each Eligible Asset was originated in the United States.

        Binding Obligation. Each Eligible Asset represents the genuine, legal,
valid and binding payment obligation of the Obligor thereon, enforceable by the
holder thereof in accordance with its terms, except as enforceability may be
limited by bankruptcy, insolvency, reorganization or similar laws affecting the
enforcement of creditors' rights generally and by equitable limitations on the
availability of specific remedies, regardless of whether such enforceability is
considered in a proceeding in equity or at law; and all parties to each Eligible
Asset had full legal capacity to execute and deliver such Eligible Asset and all
other documents related thereto and to grant the security interest purported to
be granted thereby.

        No Government Obligor. No Obligor is the United States of America or any
State or any agency, department, subdivision or instrumentality thereof.

        Obligor Bankruptcy. At the Purchase Date, no Obligor had been identified
on the records of Seller as being the subject of a current bankruptcy
proceeding.

        List of Auto Loans. The information set forth in the List of Auto Loans
is true and correct in all material respects as of the date of such list.

        Marking Records. By the Purchase Date, Seller will have caused the
portions of its electronic ledger relating to the Eligible Assets to be clearly
and unambiguously marked to show that the Eligible Assets have been sold to
Buyer under the Master Repurchase Agreement.

        Computer Tape. The Computer Tape was complete and accurate as of the
date of such tape and includes a description of the same Eligible Assets that
are described in the related List of Auto Loans.


                                      B-2
<PAGE>   24
        Chattel Paper. The Eligible Assets constitute chattel paper within the
meaning of the UCC as in effect in the states in which the Obligors reside.

        One Original. There is only one original executed copy of each Contract.

        Eligible Assets in Force. No Eligible Asset has been satisfied,
subordinated or rescinded, and the Financed Vehicle securing each such Eligible
Asset has not been released from the lien of the related Eligible Asset in whole
or in part. No provisions of any Eligible Asset have been waived, altered or
modified in any respect since its origination, except by instruments or
documents identified in the Eligible Asset File. No Eligible Asset has been
modified as a result of application of the Soldiers' and Sailors' Civil Relief
Act of 1940, as amended.

        Lawful Assignment. No Eligible Asset was originated in, or is subject to
the laws of, any jurisdiction the laws of which (a) would make unlawful, void or
voidable the sale, transfer and assignment of such Eligible Asset under this
Agreement or (b) would impair the validity or enforceability of any Eligible
Asset because of any such sale, transfer or assignment.

        Good Title. No Eligible Asset has been sold, transferred, assigned or
pledged by Seller to any Person; immediately prior to the transfer thereof
pursuant to this Agreement, Seller had good and indefeasible title to and was
the sole owner of each Eligible Asset, free of any Lien and such title is freely
assignable pursuant to the terms hereof; immediately upon the transfer and
assignment thereof herein contemplated, Buyer shall have full ownership of and
good and marketable title to each Eligible Asset, free and clear of all Liens
and rights of others, and the transfer and assignment herein contemplated has
been perfected under the UCC. Neither Seller nor any dealer has a participation
in, or other right to receive, payments or proceeds in respect of any Eligible
Asset. Seller has not taken any action to convey any right to any Person that
would result in such Person having a right to payments received under any
related insurance policies or the related Dealer Agreements or to payments due
under such Eligible Assets.

        Security Interest in Financed Vehicle. Each Eligible Asset has created a
valid, binding and enforceable first priority security interest in favor of
Seller in the related Financed Vehicle, which is in full force and effect. Each
Lien Certificate contained in the Custodian's Asset Files shows Seller, Onyx or
a Seller's Affiliate named as the original secured party under each Eligible
Asset and as the holder of a first priority security interest in such Financed
Vehicle. 


                                      B-3
<PAGE>   25
Seller's security interest in each Financed Vehicle has been validly assigned by
Seller to Buyer pursuant to this Agreement.

        All Filings Made; Valid Security Interest. All filings (including UCC
filings) necessary in any jurisdiction to give Buyer a first perfected ownership
interest in the Eligible Assets have been made.

        No Impairment. Seller has not done and will not do anything to convey
any right to any Person that would result in such Person having a right to
payments due under a Eligible Asset or otherwise to impair the rights of Buyer
in any Eligible Asset or the proceeds thereof.

        No Release. No Eligible Asset is assumable by another Person in a manner
which would release the Obligor thereof from such Obligor's obligations to
Seller with respect to such Eligible Asset.

        No Defenses. No Eligible Asset is subject to any right of rescission,
setoff, counterclaim or defense and, to the knowledge of Seller, no such right
has been asserted or threatened with respect to any Eligible Asset. The
operation of the terms of any Eligible Asset or the exercise of any right
thereunder will not render the Eligible Asset unenforceable in whole or in part
or subject to any right of rescission, setoff, counterclaim or defense, and to
the knowledge of Seller, no such right of rescission, setoff, counterclaim or
defense has been asserted with respect thereto.

        No Default. To the knowledge of Seller, there has been no default,
breach, violation or event permitting acceleration under the terms of any
Eligible Asset (other than payment delinquencies of not more than 30 days), and
no condition exists or event has occurred and is continuing that with notice,
the lapse of time or both would constitute a default, breach, violation or event
permitting acceleration under the terms of any Eligible Asset, and there has
been no waiver of any of the foregoing. As of the related Purchase Date, no
Financed Vehicle had been repossessed.

        Insurance. As of the Purchase Date, each Financed Vehicle is covered by
a vendor's single interest insurance policy (i) that provides coverage as to
such Financed Vehicle in an amount at least equal to the lesser of (a) the value
of such Financed Vehicle or (b) the principal amount due from the Obligor under
the related Eligible Asset, (ii) naming Seller and its successors and assigns as
loss payees and (iii) insuring against loss and damage due to fire, theft,
transportation, collision and other risks generally covered by comprehensive and
collision coverage and such coverage will not be voided or voidable due to 


                                      B-4
<PAGE>   26
the sales or pledges of the related Eligible Asset pursuant to this Agreement.
Each Eligible Asset requires the Obligor to maintain physical loss and damage
insurance, naming Seller and its successors and assigns as additional insured
parties, and each Eligible Asset permits the holder thereof to obtain physical
loss and damage insurance at the expense of the Obligor if the Obligor fails to
do so. No Financed Vehicle was or had previously been insured under a policy of
force-placed insurance on the related Purchase Date.

        Past Due. At the Purchase Date, no Eligible Asset is more than 30 days
past due.

        No Liens. There are no Liens or claims which have been filed, and, to
the knowledge of Seller, none pending or threatened to be filed, for work,
labor, materials or unpaid state or federal taxes affecting the vehicle securing
any Eligible Asset which are or may become liens prior or equal to the lien of
the Eligible Asset.

        Remaining Principal Balance. At each Purchase Date, the principal
balance of each Eligible Asset set forth in the List of Auto Loans is true and
accurate in all material respects.

Gentlemen:

        This letter will confirm that Onyx Acceptance Corporation, a Delaware
corporation ("Onyx"), agrees to absolutely and unconditionally guaranty to
Merrill Lynch Mortgage Capital Inc. and any of its affiliates (collectively, the
"Beneficiary"), the full and prompt payment and performance of the obligations,
undertakings and liabilities of Onyx Acceptance Funding Corporation, a Delaware
corporation ("Assignor"), arising under the terms and provisions of a Master
Repurchase Agreement (the "Agreement"), dated as of February 4, 1998 by and
between Assignor and Merrill Lynch Mortgage Capital Inc. ("MLMCI"), in an amount
not to exceed 10% of the aggregate outstanding amount owed by Assignor to MLMCI
under the Agreement (such obligations, undertakings and liabilities are herein
referred to as the "Guarantied Obligations"). Onyx hereby expressly consents to
any amendment to the Agreement as may be agreed upon by Assignor and MLMCI and
waives notice of any such amendment. A copy of the Agreement is attached hereto
as Exhibit A. Capitalized terms used and not otherwise defined herein shall have
the meanings assigned in the Agreement.

        Onyx hereby represents and warrants to you that Assignor is a direct or
an indirect wholly-owned subsidiary of Onyx.

        Onyx hereby agrees that if Assignor shall fail at any time to make due
and punctual payment to the Beneficiary of any Guarantied Obligation or if
Assignor shall fail at any time to perform any other Guarantied Obligation to
the Beneficiary, Onyx will forthwith pay such amount and perform such obligation
without demand therefor.

        Onyx covenants and agrees to immediately notify MLMCI if a
representation, warranty or covenant of Assignor under Agreement has been
breached or if an Event of Default shall have occurred.
        Onyx, to the extent permitted by law, hereby waives any requirement that
the Beneficiary take legal action against Assignor before enforcing this
guaranty; agrees that its obligations hereunder shall be unconditional,
irrespective of the validity, regularity or enforceability of the Guarantied
Obligations or the dissolution, liquidation, reorganization or other change
regarding the Assignor or the Assignor seeking protection, or having a case or
proceeding commenced against it, under any law for the protection of debtors or
creditors; waives diligence, presentment, demand for payment or performance,
protest or notice or other formality of any kind whatsoever; waives filing of
claims with any court in case of the insolvency, reorganization or bankruptcy of
the Assignor; 


                                      D-1

waives any fact, event or circumstance that might otherwise constitute a legal
or equitable defense to or discharge of Onyx, including (but without typifying
or limiting this waiver) failure by the Beneficiary to perfect a security
interest in any collateral securing performance of any Guarantied Obligation and
any delay by the Beneficiary in exercising any of its rights hereunder. Onyx
covenants that this guaranty will not be discharged except by full and final
payment and performance to the Beneficiary of all Guarantied Obligations
incurred while it is effective, and agrees that this guaranty shall continue to
be effective or be reinstated (as the case may be) if at any time all or any
part of any payment or interest thereon or other performance by Assignor is
avoided or must otherwise be restored by the Beneficiary. Onyx hereby further
consents to any renewal or modification of any Guarantied Obligation or any
extension of the time within which such is to be performed and to any other
indulgences, whether before or after the date of this guaranty.

        Onyx agrees to pay on demand all out-of-pocket expenses (including legal
fees and disbursements) incurred by the Beneficiary in connection with the
enforcement and protection of its rights hereunder.

        This is a continuing guaranty and will remain in effect until thirty
(30) days after written notice of termination is received by Merrill Lynch
Mortgage Capital Inc., Merrill Lynch World Headquarters, World Financial Center,
North Tower, 8th Floor, New York, New York 10281, Attention: Timothy M.
Loughlin. Any such termination shall not affect or reduce Onyx's obligations
hereunder for any liability of Assignor that arose prior to the expiration of
said thirty-day period. This guaranty shall terminate and shall be of no further
force or effect upon full payment of all amounts due to MLMCI under the
Agreement. This guaranty shall inure to the benefit of any successor of the
Beneficiary and be binding on any successor or assignee of Onyx.

        This guaranty shall be governed by and construed in accordance with the
laws of the State of New York. Onyx hereby agrees that (i) any dispute or
controversy arising out of or relating to this guaranty, the Agreement or the
Note shall be submitted to arbitration before the American Arbitration
Association, (ii) the arbitration proceedings shall be conducted in New York,
New York and (iii) the decision of the arbitrators shall be final and judgment
may be entered on the award. In the event that such arbitration is unavailable,
Onyx hereby submits to the jurisdiction of the United States Federal and New
York State courts situated in the City, County, and State of New York and hereby
agrees that any litigation arising out of or relating to this guaranty, the
Agreement or the Note shall be brought in such courts. Each provision and
agreement herein shall be treated as separate and independent from any other
provision or agreement herein and shall be enforceable notwithstanding the
non-enforceability of any such other provision or agreement.

        Any demand by MLMCI for payment or performance by Onyx shall be by a
written demand to Onyx, which shall be deemed to have been duly given if made by
facsimile transmission to Onyx Acceptance Corporation, 8001 Irvine Center Drive,
