                            ------------------------
 
   
    The     % Auto Loan Pass-Through Certificates (the "Certificates") will
represent undivided fractional interests in the Onyx Acceptance Grantor Trust
1996-4 (the "Trust") to be formed by Onyx Acceptance Financial Corporation (the
"Seller"), a wholly-owned, limited purpose finance subsidiary of Onyx Acceptance
Corporation ("Onyx"). The Trust property will include a pool of fixed rate Rule
of 78's and Simple Interest Method motor vehicle retail installment sales
contracts (the "Initial Contracts") secured by new and used automobiles and
light-duty trucks (the "Initial Financed Vehicles"), certain monies due under
the Initial Contracts on or after December 1, 1996 (the "Cut-Off Date"),
security interests in the Initial Financed Vehicles, the benefits of an
irrevocable principal/interest surety bond (the "Surety Bond") issued by Capital
Markets Assurance Corporation (the "Insurer"), monies on deposit in a trust
account (the "Pre-Funding Account") to be established with the trustee of the
Trust (the "Trustee") and certain other property, all as more fully described
herein. The Aggregate Scheduled Balance (as defined herein) of the Initial
Contracts as of the Cut-Off Date will be $75,932,971. From time to time on or
before March   , 1997, additional Rule of 78's and Simple Interest Method
contracts (the "Subsequent Contracts" and together with the Initial Contracts,
the "Contracts") secured by new and used automobiles and light duty trucks (the
"Subsequent Financed Vehicles" and, together with the Initial Financed Vehicles,
the "Financed Vehicles"), will be purchased by the Trust from the Seller with
monies on deposit in the Pre-Funding Account. Onyx will act as servicer of the
Contracts (the "Servicer").
    
 
    Interest on the Certificates at the Pass-Through Rate of     % per annum
(each, an "Interest Distribution"), will be distributed to the
Certificateholders on the 15th day of each month (or, if the 15th day is not a
Business Day, the following Business Day) (each, a "Distribution Date")
commencing January 15, 1997 and ending on          15, 200 (the "Final
Distribution Date"). Payments of principal, as well as the principal balance of
liquidated contracts and contracts repurchased by the Seller and purchased by
the Servicer (the "Principal Distribution"), will be distributed to
Certificateholders on each Distribution Date as described herein. In addition,
the Principal Distribution on the Distribution Date immediately following the
end of the Funding Period, which shall occur on or before March   , 1997, will
include all amounts remaining on deposit in the Pre-Funding Account.
 
    It is a condition of issuance that the Certificates be rated in the highest
category by two nationally recognized rating agencies based primarily on the
issuance of the Surety Bond by the Insurer. Under the Surety Bond, the Insurer
has unconditionally and irrevocably guaranteed payment of the Interest
Distribution and the Principal Distribution on each Distribution Date, including
the Final Distribution Date. See "The Certificates and the Agreement -- The
Surety Bond."
 
    The Certificates will initially be represented by certificates registered in
the name of Cede & Co. as the nominee of The Depository Trust Company ("DTC").
The interests of beneficial owners of the Certificates will be represented by
book entries on the records of DTC and participating members thereof. Definitive
Certificates will be available only under the limited circumstances described
herein.
 
   
    There is currently no secondary market for the Certificates, and there will
not be any application to list the Certificates on an exchange. The Underwriter
expects, but is not obligated, to make a market in the Certificates. There is no
assurance that any such market will develop or if it does develop, that it will
provide Certificateholders with liquidity of investment or will continue for the
life of the Certificates.

                             each such Subsequent Transfer Date, the Trust
                             Property will include the Subsequent Contracts
                             delivered to the Trustee on such Subsequent

Distribution Date..........  The 15th day of each month (or, if such day is not
                             a Business Day, the next succeeding Business Day)
                             commencing January 15, 1997 (each a "Distribution
                             Date"). A "Business Day" is a day other than a
                             Saturday, Sunday or other day on which commercial

                             product of one-twelfth of the Pass-Through Rate and
                             the Certificate Balance as of the end of the

                             distributed to the Certificateholders of record on
                             a pro rata basis as of the Business Day immediately
                             preceding such Distribution Date. The Certificate
                             Balance will initially equal $100,000,000 (the
                             "Original Certificate Balance") and as of any
                             Distribution Date will equal the Original
                             Certificate Balance, reduced by all previous
                             Principal Distributions, including any amounts from

                             Balance related to Contracts, from collections
                             received on the Contracts on deposit in the
                             Collection Account or previously collected and
                             available for distribution, (ii) to the extent of
                             the portion of the Certificate Balance related to
                             the Pre-Funded Amount from investment earnings
                             thereon, and from payments under the Yield
                             Supplement Agreement. A "Collection Period" with
                             respect to a Distribution Date will be the calendar
                             month preceding the month in which such
                             Distribution Date occurs; provided, that with
                             respect to Liquidated Contracts (as defined below)
                             the Collection Period will be the period from but
                             excluding the sixth Business Day preceding the
                             immediately preceding Distribution Date to and
                             including the sixth Business Day preceding such
                             Distribution Date. With respect to the first
                             Distribution Date the "Collection Period" for
                             Liquidated Contracts will be the period from and
                             including the Cut-Off Date to and including the
                             sixth Business Day preceding such first
                             Distribution Date. See "The Certificates and the
                             Agreement -- Distribution of Principal and
                             Interest."
    
 
   
Principal Distribution.....  On each Distribution Date, Principal Distributions
                             for the related Collection Period will be passed
                             through to the Certificateholders. The "Principal
                             Distribution" on any Distribution Date is the
                             Aggregate Scheduled Balance Decline (as defined
                             below) during the related Collection Period and,
                             with respect to the Distribution Date immediately
                             following the end of the Funding Period, any
                             portion of the Pre-Funded Amount remaining on
                             deposit in the Pre-Funding Account. The Principal
                             Distribution on the Final Distribution Date will
                             include the Aggregate Scheduled Balance of all
                             Contracts that are outstanding at the end of the
                             Collection Period immediately prior to the Final
                             Distribution Date. The "Aggregate Scheduled Balance
                             Decline" for any Distribution Date is the sum of
                             (x) the amount by which the Aggregate Scheduled
                             Balance of the Contracts as of the beginning of the
                             related Collection Period exceeds the Aggregate
                             Scheduled Balance of such Contracts as of the end
                             of the related Collection Period (excluding any
                             Subsequent Contracts added during the related
                             Collection Period) and (y) the amount by which the
                             Aggregate Scheduled Balance of the Subsequent
                             Contracts (determined as of each related Subsequent
                             Transfer Date) transferred to the Trust during the
                             related Collection Period exceeds the Aggregate
                             Scheduled Balance of such Contracts as of the end
                             of the related Collection Period. The "Aggregate
                             Scheduled Balance" of the Contracts is the sum of
                             the Scheduled Balance of each Contract. The
                             "Scheduled Balance" of a Rule of 78's Contract at
                             any date is equal to the Cut-Off Date Scheduled
                             Balance of such Contract reduced by the portion of
                             each scheduled payment of principal and interest
                             due on such Contract (the "Monthly P&I") on or
                             prior to the date of calculation that is allocable
                             to principal under the Recomputed Actuarial Method.
                             The Scheduled Balance of a Simple Interest Contract
                             at any date is equal to the Cut-Off Date Scheduled
                             Balance of such Contract reduced by the portion of
                             Monthly P&I on or prior to the date of calculation
                             that is allocated to principal under the Simple
                             Interest Method. The Scheduled Balance of any
                             Contract that is a Liquidated Contract or that has
                             been purchased by the Servicer or repurchased by
                             the Seller will equal zero. A "Liquidated Contract"
                             is a Contract that (a) is the subject of a Full
                             Prepayment, (b) is a Defaulted Contract and with
                             respect to which Liquidation Proceeds constituting,
                             in the Servicer's reasonable judgment, the final

                             in full on or after its Maturity Date or (d) has
                             been a Defaulted Contract for four or more
                             Collection Periods and as to which Liquidation
                             Proceeds constituting the final amounts recoverable
                             have not been received; provided, however, that in
                             any event a Contract that is delinquent in the
                             amount of five monthly payments at the end of a
                             Collection Period is a Liquidated Contract. A
                             "Defaulted Contract" with respect to any Collection
                             Period is a Contract (a) which is, at the end of
                             such Collection Period, delinquent in the amount of
                             two monthly payments or (b) with respect to which
                             the related Financed Vehicle has been repossessed
                             or repossession efforts have been commenced. See
                             "The Contracts" and "The Certificates and the
                             Agreement -- Distributions of Principal and
                             Interest."
 
The Pre-Funding Account....  The Pre-Funding Account will be maintained with the
                             Trustee and is designed solely to hold funds to be
                             applied by the Trustee during the Funding Period
                             (as defined herein) to pay to the Seller the
                             purchase price for Subsequent Contracts. Monies on
                             deposit in the Pre-Funding Account will not be
                             available to cover losses on or otherwise make any
                             payments with respect to the portion of the
                             Certificate Balance represented by Contracts.
                             Interest on the portion of the Certificate Balance
                             represented by the Pre-Funded Amount will be
                             payable from earnings received by the Trustee
                             during the related Collection Period from
                             investment of the Pre-Funded Amount on deposit in
                             the Pre-Funding Account and from payments made
                             under the Yield Supplement Agreement, and will not
                             be payable from collections on the Contracts.
 
   
                             The Pre-Funding Account will be created with an
                             initial deposit by the Seller of $24,067,029 (the
                             "Pre-Funded Amount"). The "Funding Period" will be
                             the period from the Closing Date until the earliest
                             to occur of (i) the date on which the remaining
                             Pre-Funded Amount is less than $20,000, (ii) the

                             the close of business on March   , 1997. During the
                             Funding Period, on one or more Subsequent Transfer
                             Dates (as defined herein), the Pre-Funded Amount
                             will be applied to purchase Subsequent Contracts
                             from the Seller. The Seller expects that the
                             Pre-Funded Amount will be reduced to less than
                             $20,000 by the scheduled end of the Funding Period,
                             although no assurances can be given in this regard.
                             Any portion of the Pre-Funded Amount remaining on
                             deposit in the Pre-Funding Account at the end of
                             the Funding Period will be payable as principal to
                             Certificateholders on the immediately following
                             Distribution Date. See "The Certificates and the
                             Agreement -- General" and "The Certificates and the
                             Agreement -- The Pre-Funding Account; Mandatory
                             Prepayment of the Certificates."
    
 
   
Mandatory Partial
Prepayment.................  The Certificates will be prepaid in part on the
                             Distribution Date immediately succeeding the date
                             on which the Funding Period ends in the event that
                             any portion of the Pre-Funded Amount remains on
                             deposit in the Pre-Funding Account after giving
                             effect to the sale to the Trust of all Subsequent
                             Contracts sold to the Trust during the Funding
                             Period, including any such acquisition and
                             conveyance on the date on which the Funding Period
                             ends (a "Mandatory Partial Prepayment"). The amount
                             to be distributed to Certificateholders in
                             connection with any Mandatory Partial Prepayment
                             will equal the remaining Pre-Funded Amount. See

Yield Supplement...........  Onyx will enter into the Yield Supplement Agreement
                             with the Seller, and the Seller will assign its
                             interest therein to the Trust. The purpose of the
                             Yield Supplement Agreement is to cover the
                             shortfall between interest distributable on the
                             portion of the Certificate Balance related to the
                             Pre-Funded Amount and interest which will be earned
                             by the Trust on the Pre-Funded Amount prior to the
                             time it is used to purchase Subsequent Contracts.
                             The Yield Supplement Agreement will be in effect
                             from the Closing Date until April 15, 1997, which
                             is the Distribution Date following the end of the
                             Funding Period. The Yield Supplement Agreement will
                             provide for payment of the Yield Supplement Amount
                             on or before five business days prior to each
                             Distribution Date, ending with the Distribution
                             Date on April 15, 1997. The "Yield Supplement
                             Amount," with respect to any Collection Period is
                             an amount equal to the difference between (a) one
                             month's interest on the Pre-Funded Amount on
                             deposit in the Pre-Funding Account as of the first
                             day of such Collection Period at the Pass-Through
                             Rate and (b) the earnings received by the Trustee
                             during the related Collection Period from
                             investment of the Pre-Funded Amount on deposit in
                             the Pre-Funding Account.
    
 
                             The obligation of Onyx to pay the Yield Supplement
                             Amount will be secured by funds on deposit in a
                             segregated trust account to be maintained for the
                             benefit of the Certificateholders and the Insurer
                             (the "Yield Supplement Reserve Account"). The
                             amount required to be deposited in the Yield
                             Supplement Reserve Account will initially be equal
                             to the maximum Yield Supplement Amount that may
                             become owing under the Yield Supplement Agreement
                             assuming that with respect to the Pre-Funded Amount
                             during the Funding Period, no Subsequent Contracts
                             are purchased. On each Subsequent Closing Date,
                             certain amounts shall be released to Onyx from the
                             Yield Supplement Reserve Account with respect to
                             Subsequent Contracts acquired by the Trust on each
                             Subsequent Transfer Date since the preceding
                             Subsequent Closing Date, or the Closing Date, as
                             the case may be. See "The Certificates and the
                             Agreement -- Yield Supplement Agreement and Yield
                             Supplement Reserve Account."
 
Servicing Fee..............  The Servicer will be responsible for managing,
                             administering, servicing, and making collections on
                             the Contracts. Compensation to the Servicer will
                             consist of a monthly fee (the "Servicing Fee"),
                             payable from the Trust to the Servicer on each
                             Distribution Date, in an amount equal to the
                             product of one-twelfth of 1.00% per annum (the
                             "Servicing Fee Rate") multiplied by the Pool
                             Balance as of the close of the preceding Collection
                             Period. The "Pool Balance" as of any date is the
                             Aggregate Scheduled Balance of the Contracts as of
                             such date, excluding those Contracts which, as of
                             such date, have become Liquidated Contracts or have
                             been repurchased by the Seller or purchased by the
                             Servicer. As additional compensation, the Servicer
                             will be entitled to any late fees and other
                             administrative fees and expenses or similar charges
                             collected with respect to the Contracts. The
                             Servicer or its designee will also receive as
                             servicing compensation investment earnings on
                             Eligible Investments and the amount, if any, by
                             which the outstanding principal balance of a Rule
                             of 78's Contract that is subject to a Full
                             Prepayment exceeds the

                             Scheduled Balance of such Contract. See "The
                             Certificates and the Agreement -- Servicing Fee."
 
   
Surety Bond................  On the Closing Date, the Insurer will issue a
                             principal/interest surety bond (the "Surety Bond")
                             to the Trustee pursuant to an Insurance and
                             Reimbursement Agreement (the "Insurance
                             Agreement"), dated as of December   , 1996, among
                             the Insurer, Onyx, the Seller and the Trustee.
                             Pursuant to the Surety Bond, the Insurer will
                             unconditionally and irrevocably guarantee payment
                             of the Interest Distribution and Principal
                             Distribution on each Distribution Date to the
                             Trustee for the benefit of the Certificateholders.
                             If on any Servicer Report Date the amount on
                             deposit and available in the Collection Account,
                             after giving effect to all amounts deposited or
                             payable from the Pre-Funding Account and the
                             Payahead Account and/or pursuant to the Yield
                             Supplement Agreement with respect to such
                             Distribution Date, is less than the sum of the
                             Servicing Fee, the Principal Distribution and
                             Interest Distribution for the related Distribution
                             Date, the Trustee, by delivering a notice to the
                             Insurer, shall demand payment under the Surety Bond
                             in an amount equal to such deficiency. The Insurer
                             shall pay or cause to be paid such amount to the
                             Trustee for credit to the Collection Account and
                             the Trustee shall withdraw from the Collection
                             Account and shall pay such amount to the
                             Certificateholders on the related Distribution
                             Date. On the Final Distribution Date, to the extent
                             the amount on deposit and available in the
                             Collection Account is less than all remaining
                             unpaid interest and principal on the Certificates,
                             the Insurer shall pay or cause to be paid an amount
                             equal to such shortfall. See "The Certificates and
                             the Agreement -- The Surety Bond."
    
 
   
Contracts..................  Approximately 71.0% of the Aggregate Scheduled
                             Balance of the Initial Contracts as of the Cut-Off
                             Date allocate interest and principal in accordance
                             with the Rule of 78's (the "Rule of 78's
                             Contracts"), and approximately 29.0% in accordance
                             with the Simple Interest Method (the "Simple
                             Interest Contracts"). Approximately 81.05% of the
                             Aggregate Scheduled Balance of the Initial
                             Contracts as of the Cut-Off Date was originated in
                             California, 9.88% in Arizona, 6.56% in Washington
                             and the balance in Hawaii, Nevada and Oregon. The
                             Aggregate Scheduled Balance of the Initial
                             Contracts as of the Cut-Off Date will be
                             approximately $75,932,971 with a weighted average
                             annual percentage rate of 14.82% and a weighted
                             average remaining maturity of 56.6 months. All of
                             the Contracts (including the Initial Contracts and
                             Subsequent Contracts) will have been originated by
                             automobile dealerships ("Dealers") and assigned to
                             Onyx or originated by Onyx itself. All the
                             Contracts will then have been purchased by the
                             Seller from Onyx and by the Trust from the Seller.
                             The Seller is required to repurchase certain of the
                             Contracts under certain circumstances if certain
                             representations and warranties made by the Seller
                             are incorrect in a manner that materially and
                             adversely affects the Certificateholders or the
                             Insurer. All of the Contracts will have been
                             selected by Onyx from its portfolio of motor
                             vehicle installment sales contracts based upon the
                             criteria specified in the Agreement.
    
 
                             No later than the second Business Day following the
                             Business Day on which Onyx originates or acquires a
                             Motor Vehicle Contract during the Funding Period,
                             pursuant to the Purchase Agreement, Onyx will be
                             obligated to sell, and the Seller will be obligated
                             to purchase, those

                             Motor Vehicle Contracts that meet the eligibility
                             requirements at a purchase price equal to the
                             aggregate principal amount thereof. Pursuant to the
                             Agreement and subject to the satisfaction of
                             certain conditions described herein, the Seller
                             will sell Subsequent Contracts to the Trust on each
                             Subsequent Transfer Date. Payment for each such
                             Subsequent Contract sold to the Trust shall be made
                             by release to the Seller from the Pre-Funding
                             Account of an amount equal to the amount paid by
                             the Seller to Onyx for such Subsequent Contract.
                             The aggregate principal balance of the Subsequent
                             Contracts to be conveyed to the Trust during the
                             Funding Period will not exceed $24,067,029, the
                             Pre-Funded Amount. On the Business Day preceding
                             the first Distribution Date and on the Business Day
                             preceding each Distribution Date immediately
                             following a Subsequent Transfer Date, (each such

                             the first Subsequent Closing Date) will be filed
                             and all legal opinions, officers' certificates and

                             of such Subsequent Contracts to the Trust will be
                             executed and delivered.
    
 
                             All collections of Monthly P&I, all prepayments on
                             the Contracts collected by the Servicer and all
                             amounts paid under the Surety Bond will be
                             deposited in or credited to the Collection Account.
                             Partial prepayments of Monthly P&I ("Payaheads") on
                             Rule of 78's Contracts will be transferred on the
                             Servicer Report Date to the Payahead Account, to be
                             applied against future scheduled payments of
                             Monthly P&I. Partial and full prepayments on Simple
                             Interest Contracts will be passed through to
                             Certificateholders on the Distribution Date
                             immediately following the Collection Period in
                             which such prepayments are received. All payments
                             to the Certificateholders will be made from the
                             Collection Account and certain funds remaining in
                             the Collection Account following distributions to
                             Certificateholders and others will be paid to the
                             Insurer to be promptly distributed in accordance
                             with the terms of the Insurance Agreement. See "The
                             Contracts" and "The Certificates and the
                             Agreement -- Payahead Account."
 
Optional Termination.......  The Servicer may purchase all of the Contracts on
                             any Distribution Date following a Record Date in
                             which the Pool Balance has declined to 10% or less
                             of the sum of the initial Pool Balance and the
                             aggregate principal balance (as of their respective
                             Subsequent Transfer Dates) of all Subsequent
                             Contracts conveyed to the Trust, subject to certain
                             provisions in the Agreement. See "The Certificates
                             and the Agreement -- Repurchase of Contracts."
 
Tax Status.................  In the opinion of counsel to the Seller, the Trust
                             will be classified for Federal income tax purposes
                             as a grantor trust and not as a partnership or as
                             an association taxable as a corporation.
                             Certificateholders must report their respective
                             allocable shares of income earned on Trust assets
                             and, subject to certain limitations applicable to
                             individuals, estates and trusts, may deduct their
                             respective allocable shares of reasonable servicing
                             and other fees. See "Certain Tax Consequences."
 
   
ERISA Considerations.......  The Certificates may not be purchased by employee
                             benefit plans that are subject to the Employee
                             Retirement Income Security Act of 1974, as amended
                             ("ERISA"). See "ERISA Considerations."

Rating.....................  It is a condition of issuance of the Certificates
                             that they be rated in the highest rating category
                             by two nationally recognized rating agencies. This
                             rating will be based primarily on the issuance of
                             the Surety Bond by the Insurer. See "Risk
                             Factors -- Rating."
 
Registration of the
Certificates...............  The Certificates will initially be represented by
                             certificates registered in the name of Cede & Co.
                             ("Cede"), as the nominee of The Depository Trust
                             Company ("DTC"). No person acquiring an interest in
                             a Certificate through the facilities of DTC (a
                             "Certificate Owner") will be entitled to receive a
                             Definitive Certificate representing such person's
                             interest in the Trust, except in the event that
                             Definitive Certificates are issued in certain
                             limited circumstances. See "The Certificates and
                             the Agreement."

                                  RISK FACTORS
 
LIMITED LIQUIDITY
 
   
     There is currently no secondary market for the Certificates, and there will
be no application to list the Certificates on an exchange. The Underwriter
currently intends, but is not obligated, to make a market in the Certificates.
However, there can be no assurance that the Underwriter will make such a market,
that a secondary market will develop or, if it does develop, that it will
provide Certificateholders with liquidity of investment or will continue for the
life of the Certificates.
    
 
LIMITED OPERATING HISTORY OF ONYX
 
     All of the Initial Contracts were, and all of the Subsequent Contracts
shall be, originally purchased by Onyx from Dealers or originated by Onyx itself
in accordance with credit underwriting criteria established by Onyx. In February
1994, Onyx commenced its operations as a purchaser and servicer of motor vehicle
retail installment sales contracts. Thus, Onyx has historical performance data
for only a 35 month period with respect to the motor vehicle retail installment
sales contracts it purchases and originates. Delinquencies and loan losses may
increase from existing levels in the portfolio with the passage of time.
 
   
     Onyx is still at an early stage of operations and is subject to all of the
risks inherent in the establishment of a new business enterprise and must, among
other things, continue to attract, retain and motivate qualified personnel,
support and grow its auto lending and contract servicing business, maintain its
existing relationships with automobile dealers and develop new relationships
with dealers in and beyond Onyx's present market region. Onyx experienced
operating losses from inception through December 31, 1995. Onyx's audited
operating losses for the year-ended December 31, 1994 and December 31, 1995 were
$3.5 million and $3.1 million, respectively.
    
 
CERTAIN LEGAL ASPECTS -- THE CONTRACTS
 
   
     The transfer of the Contracts to the Trust is subject to the perfection
requirements of the Uniform Commercial Code, as in effect in California ("UCC").
The Seller will take or cause to be taken such action as is required to perfect
the Trust's rights in the Contracts and will warrant that the Trust has good
title free and clear of liens and encumbrances to each Initial Contract on the
date the Certificates are issued (the "Closing Date"). The Seller will covenant
to take such actions as are necessary to ensure that the Trust will have good
title free and clear of all liens and encumbrances to each Subsequent Contract
on each related Subsequent Transfer Date and will deliver all Subsequent
Contracts to the Trustee on the related Subsequent Transfer Dates. The
Subsequent Contracts delivered on each Subsequent Transfer Date will be
physically held by the Trustee. Upon the Subsequent Closing Date, UCC-1
financing statements will be filed with respect to the related Subsequent
Contracts to continue and maintain the Trust's perfection therein. The Agreement
permits the Servicer with the consent of the Insurer (such consent not to be
unreasonably withheld) to hold the Contracts on behalf of the Trustee and the
Insurer after the filing of UCC-1 financing statements relating to the
perfection of the Trust's security interest in the Contracts. Accordingly, if
Onyx or the Seller sell and deliver a Contract to another purchaser, there is a
risk that the purchaser could acquire an interest in the Contract superior to
the interest of the Trust and the Certificateholders. Onyx will agree in the
Agreement to take all necessary action to preserve and protect the Trust's
ownership interest in the Contracts. The Seller will represent that each
Contract is secured by a Financed Vehicle. After a Contract is purchased or
originated by Onyx and the appropriate application is processed by the
department of motor vehicles or similar state agency responsible for vehicle
records, the certificate of title (or computerized title record in the case of
Contracts originated in California, for which there will be no paper
certificates) to the Financed Vehicle securing the Contract shows Onyx as the
secured party holding a lien in the Financed Vehicle. When Contracts are sold to
the Seller and then to the Trust, Onyx remains the secured party named on the
related certificates of title (or computerized title records in the case of
Contracts originated in California), and such certificates (or electronic
records) are not endorsed or otherwise marked to identify the Trustee as secured
party, due to the administrative burden and expense of applying to the
department of motor vehicles or similar state agency in each of the states of
Contract origination to identify the Trustee as secured party, and because
retaining
    
 
                                       11
<PAGE>   13
 
   
Onyx's name as secured party enables Onyx to more efficiently service the
Contracts. Even though the Trust is not identified as secured party, because the
Trust has a security interest in the Contracts, it is the beneficial owner of
the security interest in the related Financed Vehicles. There exists a risk in
not identifying the Trust as the new secured party on the certificate of title
(or computerized title record) that, through fraud or negligence, the security
interest of the Trust could be released. Moreover, statutory liens for repairs
or unpaid taxes may have priority even over perfected security interests in the
Financed Vehicles. Notwithstanding the failure of the Trust to have obtained a
valid, first priority security interest in a Financed Vehicle, the Insurer will
remain unconditionally and irrevocably obligated on its guarantee of the
Interest Distribution and the Principal Distribution on each Distribution Date.
See "Certain Legal Aspects of the Contracts."
    
 
CERTAIN LEGAL ASPECTS -- BANKRUPTCY CONSIDERATIONS
 
     It is intended by Onyx and the Seller that the transfer of the Contracts by
Onyx to the Seller constitute a "true sale" of the Contracts to the Seller. If
the transfer constitutes such a "true sale," the Contracts and the proceeds
thereof would not be part of Onyx's bankruptcy estate should it become the
subject of a bankruptcy case subsequent to the transfer of the Contracts to the
Seller.
 
     The Seller has taken steps in structuring the transactions contemplated
hereby that are intended to ensure that the voluntary or involuntary application
for relief by Onyx under the United States Bankruptcy Code or similar state laws
("Insolvency Laws") will not result in consolidation of the assets and
liabilities of the Seller with those of Onyx. These steps include the creation
of the Seller as a separate, limited-purpose subsidiary pursuant to a
certificate of incorporation containing certain limitations (including
restrictions on the nature of the Seller's business and a restriction on the
Seller's ability to commence a voluntary case or proceeding under any Insolvency
Law without the prior unanimous affirmative vote of all of its directors).
However, there can be no assurance that the activities of the Seller would not
result in a court concluding that the assets and liabilities of the Seller
should be consolidated with those of Onyx in a proceeding under any Insolvency
Law. If a court were to reach such a conclusion, then delays in distributions on
the Certificates could occur or reductions in the amounts of such distributions
could result. Notwithstanding the holding by a court that the assets and
liabilities of the Seller should be consolidated with those of Onyx in a
proceeding under any Insolvency Law, the Insurer will remain unconditionally and
irrevocably obligated on the Surety Bond to guarantee payment of the Interest
Distribution and Principal Distribution on each Distribution Date. See "The
Seller."
 
     In Octagon Gas Systems, Inc. v. Rimmer, 995 F.2d 948, (10th Cir. 1993)
cert. denied, 114 S. Ct. 554 (1993), the United States Court of Appeals for the
10th Circuit suggested that even where a transfer of accounts from a seller to a
buyer constitutes a "true sale," the accounts would nevertheless constitute
property of the seller's estate in a bankruptcy of the seller. If Onyx or the
Seller were to become subject to a bankruptcy proceeding and a court were to
follow the Octagon Gas court's reasoning, Certificateholders might experience
delays in payment or possibly losses on their investment in the Certificates.
Counsel to the Seller has advised the Seller that the reasoning of the Octagon
Gas case appears to be inconsistent with precedent and the Uniform Commercial
Code. See "The Seller."
 
PREPAYMENT CONSIDERATIONS
 
   
     The rate of distribution of principal on the Certificates will depend on
the rate of payment (including prepayments, liquidations and repurchases by the
Seller or purchases by Onyx under certain conditions) on the Contracts which is
not possible to predict and, as discussed under "Mandatory Partial Prepayment"
immediately below, on whether sufficient additional Motor Vehicle Contracts are
generated for purchase with the Pre-Funded Amount before the end of the Funding
Period. Any full prepayments and repurchases of the Contracts can reduce the
average life of the Contracts and the aggregate interest received by the
Certificateholders over the life of the Certificates. Prepayments on Simple
Interest Contracts will shorten the average life of such Contracts and,
therefore, of the Certificates, because they will be passed through to
Certificateholders on the Distribution Date immediately following the Collection
Period in which such prepayments are received. Partial prepayments on Rule of
78's Contracts will be treated as Payaheads and accordingly will not affect the
average life of the Contracts because such payments will be held in the name of
    
 
                                       12
<PAGE>   14
 
Bankers Trust Company, acting on behalf of the Obligors and the
Certificateholders, as their interests may appear, until passed through in
accordance with the original schedule of payments for such Contracts. See "The
Certificates and Agreement -- Payahead Account."
 
   
     Onyx began purchasing Motor Vehicle Contracts in February 1994, and thus
has records of the historical prepayment experience of its Motor Vehicle
Contract portfolio only for the past 35 months. No assurance can be given that
prepayments on the Contracts will conform to any historical experience, and no
prediction can be made as to the actual prepayment rates which will be
experienced on the Contracts. See "-- Limited Operating History of Onyx" and
"Maturity and Prepayment Assumptions." Certificateholders will bear all
reinvestment risk resulting from the rate of prepayment of the Contracts.
    
 
   
MANDATORY PARTIAL PREPAYMENT
    
 
   
     The rate of distribution of principal on the Certificates will in part
depend on whether sufficient additional Motor Vehicle Contracts are generated
for purchase with the Pre-Funded Amount before the end of the Funding Period. No
assurances can be given that sufficient Subsequent Contracts will be generated
to avoid Mandatory Partial Prepayment of the Certificates. In the event Onyx
does not generate, for purchase by the Trust, sufficient Subsequent Contracts to
avoid Mandatory Partial Prepayment of the Certificates, the weighted average
life of the Certificates will be shortened by any such Mandatory Partial
Prepayment under the circumstances described under "The Certificates and the
Agreement -- The Pre-Funding Account; Mandatory Partial Prepayment of the
Certificates." Certificateholders will bear all reinvestment risk resulting from
the payment of the Pre-Funded Amount due to Onyx's inability to generate
sufficient additional Motor Vehicle Contracts during the Funding Period.
    
 
   
     Upon the occurrence of a Mandatory Partial Prepayment, the holders of
Certificates will receive an amount equal to the portion of the Pre-Funded
Amount remaining in the Pre-Funding Account. It is anticipated that the
aggregate principal amount of Subsequent Contracts sold to the Trust during the
Funding Period will not be exactly equal to the Pre-Funded Amount and that
therefore there will be at least a nominal amount of principal prepaid to
Certificateholders.
    
 
GEOGRAPHIC CONCENTRATION
 
   
     Economic conditions in the states where the obligors under the Contracts
(each, an "Obligor") reside may affect the delinquency, loan loss and
repossession experience of the Trust with respect to the Contracts.
Approximately 81.0% of the Aggregate Scheduled Balance of the Initial Contracts
as of the Cut-Off Date was originated in California, 9.9% in Arizona, 6.6% in
Washington and 2.5% in Hawaii, Nevada and Oregon combined. Accordingly, adverse
economic conditions or other factors particularly affecting California, Arizona
or Washington could adversely affect the delinquency, loan loss or repossession
experience of the Trust with respect to the Contracts.
    
 
LIMITED ASSETS
 
     The Trust does not have, nor is it permitted or expected to have, any
significant assets or sources of funds other than the Contracts and amounts on
deposit in the Pre-Funding Account and the right to receive payments under the
Surety Bond. The Certificates represent interests solely in the Trust and will
not be insured or guaranteed by the Seller, the Servicer, the Trustee or any
other person or entity except the Insurer. Consequently, holders of the
Certificates will only be able to look to payments on the Contracts and the
Surety Bond for payment.
 
RATING
 
     It is a condition of issuance of the Certificates that they be rated in the
highest rating category by two nationally recognized rating agencies. A security
rating is not a recommendation to buy, sell or hold securities and may be
revised or withdrawn at any time by the assigning rating agency. There can be no
assurance that a rating will not be lowered or withdrawn if, in the sole
judgment of a rating agency, circumstances in the future so warrant, including a
downgrading of the Insurer. The Seller cannot predict with certainty what effect
any revision or withdrawal of a rating may have on the liquidity or market value
of the Certificates. Such ratings of
 
                                       13
<PAGE>   15
 
the Certificates address the likelihood of the timely payment of each scheduled
Interest Distribution and Principal Distribution, which are guaranteed by the
Insurer pursuant to the Surety Bond. Therefore, the ratings are primarily
dependent on the rating of the Insurer, and a change in the Insurer's rating may
affect the ratings of the Certificates. See "Description of the Insurer" for a
description of the Insurer's rating.
 
BOOK-ENTRY REGISTRATION
 
     The Certificates initially will be registered in the name of Cede, the
nominee for DTC, and will not be registered in the names of the Certificate
Owners or their nominees. Because of this, unless and until Definitive
Certificates are issued, Certificate Owners will not be recognized by the
Trustee as Certificateholders, as that term is used in the Agreement. Hence,
until such time, Certificate Owners will only be able to receive payments from,
and exercise the rights of Certificateholders indirectly through, DTC and its
participating organizations, and, unless a Certificate Owner requests a copy of
any such report from the Trustee, will receive reports and other information
provided for only if, when and to the extent provided to Certificate Owners by
DTC and its participating organizations. In addition, the ability of Certificate
Owners to pledge Certificates to persons or entities that do not participate in
the DTC system, or otherwise take actions in respect of such Certificates, may
be limited due to the lack of physical certificates for such Certificates. See
"Description of the Certificates and the Agreement -- Book Entry Registration"
and "-- Definitive Certificates."
 
                                   THE TRUST
 
   
     Pursuant to the Agreement, the Seller will establish the Onyx Acceptance
Grantor Trust 1996-4 (the "Trust") by selling and assigning the following
property to Bankers Trust Company in its capacity as trustee of the Trust (the
"Trustee") in exchange for the Certificates executed and authenticated by the
Trustee: (i) the Initial Contracts purchased from the Seller and, in the case of
Subsequent Contracts, Contracts purchased on or before March   , 1997 and
secured by Financed Vehicles, (ii) certain documents relating to the Contracts,
(iii) certain monies due under the Contracts on or after the Initial Cut-Off
Date or Subsequent Transfer Date, as applicable, (iv) security interests in the
Financed Vehicles and the rights to receive proceeds from claims on certain
insurance policies covering the Financed Vehicles or the Obligors and the right
to certain proceeds under the Blanket Insurance Policy, (v) all amounts on
deposit in the Collection Account, including all Eligible Investments credited
thereto (but excluding any income on Eligible Investments, which will be paid to
the Servicer), (vi) the right of the Seller under the Purchase Agreement to
cause Onyx to repurchase certain Contracts under certain circumstances, (vii)
all right, title and interest of the Seller under the Yield Supplement
Agreement, (viii) funds on deposit in the Pre-Funding Account, and (ix) all
proceeds of the foregoing. The Trust Property will also include the benefits of
the Surety Bond of the Insurer, proceeds of which will be available to the
Trustee in the event collections from Obligors are insufficient to pay the
Interest Distributions and Principal Distributions to Certificateholders and
unpaid principal and interest on the Certificates on the Final Scheduled
Distribution Date. Each Certificate will represent a fractional undivided
interest in the Trust.
    
 
   
     The Pool Balance as of the Cut-Off Date will equal the Aggregate Scheduled
Balance of the Initial Contracts as of such date. The Pool Balance will be
increased during the Funding Period by the aggregate principal amount of
Subsequent Contracts conveyed to the Trust on each Subsequent Transfer Date
during the Funding Period. Any such additions of Subsequent Contracts will be
conditioned on the compliance with the procedures described in the Agreement.
The Seller will confirm on each such Subsequent Transfer Date that the
representations and warranties set forth in the Agreement with respect to such
Subsequent Contracts are true and correct. The Seller expects that substantially
all of the Pre-Funded Amount will be applied to purchase Subsequent Contracts by
the scheduled end of the Funding Period; however, there can be no assurance that
a sufficient amount of Motor Vehicle Contracts will be available for such
purpose. If the Pre-Funded Amount has not been reduced to zero by the end of the
Funding Period, the remaining portion thereof will be distributed to
Certificateholders as a prepayment of principal as described under "The
Certificates and the Agreement -- The Pre-Funding Account; Mandatory Partial
Prepayment of the Certificates."
    
 
                                       14

     The Trust will be formed for this transaction pursuant to the Agreement
and, prior to formation, will have had no assets or obligations. After
formation, the Trust will not engage in any activity other than acquiring and
holding the Contracts, issuing the Certificates, distributing payments thereon
and as otherwise described herein and as provided in the Agreement. The Trust
will not acquire any Motor Vehicle Contracts or assets other than the Trust
Property and will not have any need for additional capital resources. As the
Trust does not have any operating history and will not engage in any significant
activity other than issuing the Certificates and making distributions thereon,
no historical or pro forma financial statements or ratio of earnings to fixed
charges with respect to the Trust have been included.
 
                 THE ONYX PORTFOLIO OF MOTOR VEHICLE CONTRACTS
 
PURCHASE AND ORIGINATION OF MOTOR VEHICLE CONTRACTS
 
   
     Onyx's portfolio of retail installment sales contracts and installment loan
agreements are secured by new and used automobile and light-duty trucks ("Motor
Vehicle Contracts"). The Initial Contracts were, and Subsequent Contracts will
be, originated by Dealers and purchased by Onyx, except for a limited number of
Initial Contracts and Subsequent Contracts which will be originated by Onyx
itself. All of the Initial Contracts were, and Subsequent Contracts will be,
subsequently sold to the Seller and then to the Trust. Onyx currently has
agreements with 1,373 Dealers, of which 86% are franchised new car dealerships
and 14% are independent used car dealerships. The Dealers are located in
metropolitan areas in the states in which the Contracts are or will be
originated, which are California, Arizona, Washington, Oregon, Hawaii and
Nevada. Each Dealer from which Onyx purchases Contracts has entered into an
agreement with Onyx whereby the Dealer represents that it will comply with
federal and state laws regarding motor vehicle financing, that the Dealer will
obtain the requisite financial information required of the Obligor in order to
extend credit, and that the Dealer will truthfully disclose to Onyx such
financial information, the identity of the Obligor and other information in
connection with the loan transaction. The Dealers with whom Onyx has agreements
and Dealers with whom Onyx would like to have agreements are regularly contacted
by Onyx account managers by telephone and in person in an effort to obtain a
continued supply of Motor Vehicle Contracts for Onyx to purchase. Before
purchasing Contracts from independent used car Dealers, Onyx completes a credit
review of the Dealer's financial condition (including a review of financial
information provided by the Dealer and a Dun & Bradstreet report on the Dealer)
and a review of the underwriting criteria used by the Dealer.
    
 
   
     Approximately 81.0% of the Aggregate Scheduled Balance of the Initial
Contracts as of the Cut-Off Date were originated in California, 9.9% in Arizona,
6.6% in Washington and the balance in Oregon, Hawaii and Nevada. See "Risk
Factors -- Geographic Concentration." The payment obligations of the Obligor
under each Motor Vehicle Contract are secured by the vehicle purchased with the
loan proceeds provided under that Motor Vehicle Contract (the "Financed
Vehicle").
    
 
     Onyx services all of the Motor Vehicle Contracts and will continue to serve
as the primary servicer after the Motor Vehicle Contracts are sold by the Seller
to the Trust. The servicing functions performed by Onyx include customer
service, document filekeeping, computerized account recordkeeping, vehicle title
processing and collections.
 
UNDERWRITING OF MOTOR VEHICLE CONTRACTS
 
     Onyx underwrites the Motor Vehicle Contracts through its eight regional
contract purchasing offices ("Auto Finance Centers"), six of which are in
California and one in each of Arizona and Washington. Contracts purchased from
Hawaii, Oregon and Nevada are currently underwritten in either the California or
Washington Auto Finance Centers. Each Motor Vehicle Contract is fully amortizing
and provides for level payments over its term with the portion of principal and
interest of each level payment determined either on the basis of the Rule of
78's or the Simple Interest Method. See "The Contracts."
 
     To evaluate the potential purchase of a Motor Vehicle Contract, Onyx
reviews the application package received from the Dealer originating the Motor
Vehicle Contract, or in the case of Contracts originated by Onyx the application
package received from the Obligor, that sets forth the Obligor's income,
liabilities, credit
 
                                       15
<PAGE>   17
 
   
and employment history, and other personal information, as well as a description
of the Financed Vehicle that secures the Motor Vehicle Contract. The credit
applications do not consist of forms provided by Onyx. However, at the time a
Dealer underwrites a Motor Vehicle Contract, Onyx reviews the related
application for completeness and for compliance with Onyx's underwriting
guidelines and applicable federal and state consumer statutes and regulations.
To evaluate credit applications, Onyx reviews information in the application and
from credit bureau reports obtained by Onyx.
    
 
     Each proposed Motor Vehicle Contract is evaluated using uniform
underwriting standards developed by Onyx. These underwriting standards are
intended to assess the Obligor's ability to repay all amounts due under the
Motor Vehicle Contract and the adequacy of the Financed Vehicle as collateral,
based upon a review of the information contained in the Motor Vehicle Contract
application. Among the criteria considered by an Onyx credit manager in
evaluating the individual applications are (i) stability of the Obligor with
specific regard to the Obligor's occupation, length of employment and length of
residency, (ii) the Obligor's payment history based on information known
directly by Onyx or as provided by various credit reporting agencies with
respect to present and past debt, (iii) a debt service-to-gross monthly income
ratio test, and (iv) the principal amount of the Motor Vehicle Contract taking
into account the age, type and market value of the Financed Vehicle. The general
policy of Onyx has been not to allow an Obligor's debt service-to-gross monthly
income ratio to exceed 45%.
 
     After review of an application, an Onyx credit manager, via an electronic
system utilized by Onyx, communicates an appropriate decision to the Dealer, or
by telephone or otherwise to the Obligor in the case of Motor Vehicle Contracts
originated by Onyx, specifying approval (subject to the receipt of the required
documentation), denial or a counter-offer on the proposed Motor Vehicle
Contract. If the response to the Dealer or Obligor requires stipulations to the
approval, (including an additional downpayment, reduction in the term of the
financing, or the addition of a co-signer to the Motor Vehicle Contract), these
are communicated concurrently to the Dealer or Obligor, and become a condition
of the approval. Subsequent to approval, the Dealer will (if Onyx is the chosen
source of financing) forward the necessary documentation to Onyx, which consists
of the following: (i) a signed application; (ii) the only original and a copy of
the executed contract; (iii) an agreement by the Obligor to provide insurance;
(iv) a report of sale or guarantee of title; (v) an application for
registration; (vi) a co-signer notification (if applicable); (vii) a copy of any
supplemental warranty purchased with respect to the Financed Vehicle; (viii)
vehicle valuation documentation acceptable to Onyx; and (ix) any other required
documentation.
 
     Once the appropriate documentation is in hand for funding, the file
relating to the Motor Vehicle Contract is ready to forward to an Onyx contract
processor for a pre-funding audit. The contract processor then audits such
documents for completeness and consistency with the application, providing final
approval for purchase of the Motor Vehicle Contract once these requirements have
been satisfied (subject to the receipt of the required documentation).
 
     The amount advanced by Onyx under any Motor Vehicle Contract does not
exceed (i) for a new Financed Vehicle, the manufacturer's suggested retail price
plus taxes, title and license fees, extended warranty (if any) and credit
insurance, or (ii) for a used Financed Vehicle, the value assigned by a
nationally recognized used car value guide, plus taxes, title and license fees
and extended warranty (if any). However, the actual amount advanced for a Motor
Vehicle Contract is often less than the maximum permissible amount depending on
a number of factors, including the length of the Motor Vehicle Contract term and
the model and year of the Financed Vehicle. These adjustments are made to assure
that the Financed Vehicle constitutes adequate collateral to secure the Motor
Vehicle Contract. Under no circumstances is the amount advanced for a Motor
Vehicle Contract greater than the amount payable by the Obligor with respect to
the purchase of the Financed Vehicle.
 
     Periodically, Onyx makes a detailed analysis of its portfolio of Motor
Vehicle Contracts to evaluate the effectiveness of Onyx's credit guidelines. If
external economic factors, credit delinquencies or credit losses change, Onyx
adjusts its credit guidelines to maintain the asset quality deemed acceptable by
Onyx's management. Onyx reviews, on a daily basis, the quality of its Motor
Vehicle Contracts by conducting audits
 
                                       16
<PAGE>   18
 
of certain randomly selected Motor Vehicle Contracts to ensure compliance with
established policies and procedures.
 
INSURANCE
 
   
     Each related Motor Vehicle Contract requires the Obligor to obtain
comprehensive and collision insurance with respect to the related Financed
Vehicle with Onyx as a loss payee. To protect against Obligors who do not obtain
any insurance, or who do not obtain the right type or level of insurance, Onyx
has purchased limited comprehensive and collision insurance, referred to as the
"Blanket Insurance Policy" coverage. The Blanket Insurance Policy provides Onyx
with protection on each uninsured or underinsured Financed Vehicle against total
loss, damage or theft. Onyx has obtained its Blanket Insurance Policy from
United Financial Casualty Company, which is rated "A" by A.M. Best & Co. For the
Blanket Insurance Policy, Onyx is assessed a premium based on each Motor Vehicle
Contract acquired. The insurer under the Blanket Insurance Policy is required to
settle any claim complying with the policy conditions within 60 days from the
date reported. Onyx has paid the premium for the Blanket Insurance Policy
allocable to each Initial Contract sold to the Trust prior to such Initial
Contract's sale to the Trust and will pay the premium at each Subsequent Closing
Date for the Subsequent Contracts. The proceeds under the Blanket Insurance
Policy, to the extent they relate to any Contract, will constitute part of the
Trust Property.
    
 
COLLECTION PROCEDURES
 
     Collection activities with respect to delinquent Motor Vehicle Contracts
are performed by Onyx at its eight Auto Finance Centers. Collection activities
include prompt investigation and evaluation of the causes of any delinquency. An
Obligor is considered delinquent when he or she has failed to make a scheduled
payment under the Motor Vehicle Contract within 30 days of the related due date
(each, a "Due Date").
 
     To automate its collection procedures, Onyx uses features of the computer
system of its third party service bureau, Online Computer Systems, Inc. ("OCS")
to provide tracking and notification of delinquencies. The collection system
provides relevant Obligor information (for example, current addresses, phone
numbers and loan information) and records of all Motor Vehicle Contracts. The
system also records an Obligor's promise to pay and affords supervisors the
ability to review collection personnel activity and to modify collection
priorities with respect to Motor Vehicle Contracts. Onyx utilizes a predictive
dialing system centrally located within its Irvine headquarters to make phone
calls to Obligors whose payments are past due by more than five days but less
than 30 days. The predictive dialer is a computer-controlled telephone dialing
system which dials phone numbers of Obligors from a file of records extracted
from Onyx's database. By eliminating time wasted on attempting to reach
Obligors, the system gives a single collector, on average, the ability to speak
with and work 300 to 350 accounts per day. Once a live voice responds to the
automated dialer's call, the system automatically transfers the call to a
collector and the relevant account information to the collector's computer
screen. The system also tracks and notifies collection management of phone
numbers that the system has been unable to reach within a specified number of
days, thereby promptly identifying for management all Obligors who cannot be
reached by telephone.
 
     Once an Obligor is 30 days or more delinquent, those accounts are assigned
to specific collectors at the Irvine Collection Center who have primary
responsibility for such delinquent account until it is resolved. To expedite
collections from late paying Obligors, Onyx uses Western Union "Quick Collect,"
which allows an Obligor to pay at numerous locations any late payments and Onyx
to print at its Irvine headquarters a check evidencing the payment. Onyx also
uses an automatic payment system that allows an Obligor to authorize Onyx to
present a draft on the Obligor's bank account directly to the Obligor's bank for
payment to Onyx.
 
     Generally, after a scheduled payment under a Motor Vehicle Contract
continues to be past due for 45 days, Onyx will initiate repossession of the
Financed Vehicle. However, if a Motor Vehicle Contract is deemed uncollectible,
if the Financed Vehicle is deemed by collection personnel to be in danger of
being damaged, destroyed or made unavailable for repossession, or if the Obligor
voluntarily surrenders the Financed Vehicle, Onyx may repossess it without
regard to the length or existence of payment delinquency. Repossessions are
conducted by third parties who are engaged in the business of repossessing
vehicles for secured parties. Under California law, after repossession, the
Obligor generally has an additional 15 days to
 
                                       17
<PAGE>   19
 
redeem the Financed Vehicle before the Financed Vehicle may be resold by Onyx in
an effort to recover the balance due under the Motor Vehicle Contract.
 
     Losses may occur in connection with delinquent Motor Vehicle Contracts and
can arise in several ways, including inability to locate the Financed Vehicle or
the Obligor, or because of a discharge of the Obligor in a bankruptcy
proceeding. The current policy of Onyx is to recognize losses at the time a
Motor Vehicle Contract is deemed uncollectible or during the month a scheduled
payment under a Motor Vehicle Contract becomes 120 days or more past due,
whichever occurs first.
 
     Upon repossession and sale of the Financed Vehicle, any deficiency
remaining is pursued against the Obligor to the extent deemed practical by Onyx
and to the extent permitted by law. The loss recognition and collection policies
and practices of Onyx may change over time in accordance with Onyx's business
judgment. However, the Agreement requires that Onyx service the Contracts and
collect all amounts due using reasonable care and in at least the same manner as
it services and collects amounts due with respect to Motor Vehicle Contracts
serviced by it for its own account.
 
MODIFICATIONS AND EXTENSIONS
 
     Onyx offers certain credit-related extensions to Obligors. Generally, these
extensions are offered only when (i) Onyx believes that the Obligor's financial
difficulty has been resolved or will no longer impair the Obligor's ability to
make future payments, (ii) the extension will result in the Obligor's payments
being brought current, (iii) the total number of credit-related extensions
granted on the Motor Vehicle Contract will not exceed three and the total
credit-related extensions granted on the Motor Vehicle Contract will not exceed
three months in the aggregate, (iv) there have been no credit-related extensions
granted on the Motor Vehicle Contract in the immediately preceding twelve
months, and (v) Onyx (or its assignee) had held the Motor Vehicle Contract for
at least six months. Any deviation from this policy requires the concurrence of
Onyx's collection manager and an Auto Finance Center manager.
 
DELINQUENCY AND LOAN LOSS INFORMATION
 
     The following tables set forth information with respect to the experience
of Onyx relating to delinquencies, loan losses and recoveries for the portfolio
of Motor Vehicle Contracts owned and serviced by Onyx on a quarterly basis
commencing December 31, 1994. The tables include delinquency information
relating to those Motor Vehicle Contracts that were purchased, originated, sold
and serviced by Onyx. All of the Motor Vehicle Contracts were originally
purchased by Onyx from Dealers or originated by Onyx itself in accordance with
credit underwriting criteria established by Onyx. In February 1994, Onyx
commenced its operations as a purchaser and servicer of motor vehicle retail
installment sales contracts. Thus, Onyx has historical performance for only a
limited time period with respect to the Motor Vehicle Contracts it purchases and
originates and thus delinquencies and loan losses may increase from existing
levels in the portfolio with the passage of time. Delinquency and loan loss
experience may be influenced by a variety of economic, social and other factors.
See "Risk Factors."
 
     The delinquency and loss levels of the Motor Vehicle Contracts at September
30, 1996 were higher than in prior periods due to the performance of Motor
Vehicle Contracts originated in prior quarters through Onyx's North Hollywood
Auto Finance Center. The North Hollywood Auto Finance Center had a higher
concentration of used car dealerships than Onyx's other Auto Finance Centers,
and this concentration of used car dealerships was principally responsible for
the deterioration in the performance of Onyx's portfolio during the second and
third quarters.
 
   
     To address the performance issues of this center, following the end of the
second quarter of 1996 management reevaluated all used car dealerships from
which Onyx purchases Motor Vehicle Contracts to ensure that such dealerships
meet Onyx's underwriting criteria, and Onyx terminated its relationships with a
majority of the used car dealerships serviced by the North Hollywood Auto
Finance Center. Originations in the North Hollywood office, as a result, have
declined in value.
    
 
     During the third quarter of 1996 management further enhanced the credit
review process by promoting a senior credit manager to the position of Chief
Credit Officer and by increasing staffing in the credit review

department. This department continues to audit contracts within a few days after
funding. The results of the audits are communicated back to the originating
office on a daily basis.

                                 THE CONTRACTS
 
     Each of the Initial Contracts in the Trust is, and all Subsequent Contracts
in the Trust will be, fixed rate contracts where the allocation of each payment
between interest and principal is calculated using the Rule of 78's or the
Simple Interest Method. Such Contracts using the Rule of 78's provide for the
payment by the Obligor of a specified total amount of payments, payable in equal
monthly installments, which total represents the principal amount financed plus
add-on interest in an amount calculated as if such Contract were a
self-amortizing, level-yield Contract bearing interest at a per annum rate equal
to the stated annual percentage rate as set forth in the Contract ("APR"). Under
the Rule of 78's, the amount of each payment allocable to interest on a Contract
is determined by multiplying the total amount of add-on interest payable over
the term of the Contract by a fraction derived as described below. The fraction
used in the calculation of add-on interest earned each month under a contract
governed by the Rule of 78's has as its denominator a number equal to the sum of
a series of numbers representing the total number of monthly payments due under
the Contract. For example, with a Contract providing for 12 payments, the
denominator of each month's fraction will be 78, the sum of a series of numbers
from 1 to 12. The numerator of the fraction for a given month is the number of
payments remaining before giving effect to the payment to which the fraction is
being applied. Accordingly, in the example of a twelve-payment Contract, the
fraction for the first payment is 12/78, for the second payment 11/78, for the
third payment 10/78, and so on through the final payment, for which the fraction
is 1/78. The applicable fraction is then multiplied by the total add-on interest
payment over the entire term of the Contract, and the resulting amount is the
amount of add-on interest earned that month. The difference between the amount
of the monthly payment by the Obligor and the amount of earned add-on interest
calculated for the month is applied to principal reduction.
 
     For Contracts using the "Simple Interest Method" interest due is calculated
on the Due Date based on the actual principal balance of the Contract on that
date. For such Contracts, interest accrued as of the Due Date is paid first, and
then the remaining payment is applied to the unpaid principal balance.
Accordingly, if an Obligor pays the fixed monthly installment in advance of the
Due Date, the portion of the payment allocable to interest for the period since
the preceding payment will be less than it would be if the payment were made on
the Due Date, and the portion of the payment allocable to reduce the principal
balance will be correspondingly greater. Conversely, if an Obligor pays the
fixed monthly installment after its Due Date, the portion of the payment
allocable to interest for the period since the preceding payment will be greater
than it would be if the payment were made on the Due Date, and the portion of
the payment allocable to reduce the principal balance will be correspondingly
smaller. When necessary, an adjustment is made at the maturity of the Contract
to the scheduled final payment to reflect the larger or smaller, as the case may
be, allocations of payments to the amount financed under the Contract as a
result of early or late payments, as the case may be.
 
   
     The purchase price paid by the Trust for each Contract will reflect the
principal balance of such Contract as of the Cut-Off Date calculated either
under the Rule of 78's or the Simple Interest Method (the "Cut-Off Date
Scheduled Balance"). For Rule of 78's Contracts a greater portion of the early
payments under a Contract is allocated to interest than would be the case using
the actuarial method. Therefore, the Cut-Off Date Scheduled Balance of each Rule
of 78's Contract exceeds the amount that would have been its principal balance
as of the Cut-Off Date if each Contract had been amortized from origination
under the actuarial method. The Trustee and the Servicer intend to account for
interest and principal on the Rule of 78's Contracts using the actuarial method,
but based on the Cut-Off Date Scheduled Balance. The remaining payments due on a
Rule of 78's Contract are not sufficient to amortize the Cut-Off Date Scheduled
Balance of such Contract at a yield equal to its APR. Accordingly, in order to
amortize the Cut-Off Date Scheduled Balance over the remaining term of the Rule
of 78's Contract using the actuarial method of accounting, the Servicer will
recompute the effective yield of such Contract based on the remaining payments
due and the Cut-Off Date Scheduled Balance (such yield, stated as a per annum
rate, the "Recomputed Yield") and will allocate each payment of Monthly P&I
between principal and interest on each Rule of 78's Contract based on the
Cut-Off Date Scheduled Balance and the Recomputed Yield for such Contract (such
method, the "Recomputed Actuarial Method").
    
 
     The Initial Contracts were, and the Subsequent Contracts will be, selected
from the Motor Vehicle Contracts in the portfolio of Onyx using the following
criteria (the "Eligibility Requirements"). No selection

procedures used with respect to the Initial Contracts were, or, with respect to
the Subsequent Contracts, shall be, adverse to the Certificateholders or the
Insurer. Approximately 23.94% of the Aggregate Scheduled Balance of the Initial
Contracts, as of the Cut-Off Date, were secured by new Financed Vehicles and
approximately 76.06% of the Aggregate Scheduled Balance of the Initial
Contracts, as of the Cut-Off Date, were secured by used Financed Vehicles. The
Seller may not substitute other Motor Vehicle Contracts for the Contracts at any
time during the term of the Agreement.

(1) The APRs set forth herein are the APRs of the Initial Contracts. Because the
    principal balance of each Initial Contract sold to the Trust is the Cut-Off
    Date Scheduled Balance, which in the case of Rule of 78's Contracts is
    higher than what the principal balance of the Rule of 78's Contracts would
    have been had principal and interest been allocated from the date of
    origination in accordance with the actuarial method, the Recomputed Yield
    for each Initial Rule of 78's Contract is less than the APR of such Initial
    Contract specified herein. On a weighted average basis, the yield for all
    the Contracts using the Recomputed Yield for the Initial Rule of 78's
    Contracts, in the aggregate, is      %. See "The Contracts."

</TABLE>
    
 
                      MATURITY AND PREPAYMENT ASSUMPTIONS
 
     The Contracts are prepayable in full by the Obligors at any time without
penalty. Prepayments on Simple Interest Contracts will be passed through to
Certificateholders on the Distribution Date following the Collection Period in
which they are received. Partial prepayments on Rule of 78's Contracts however
will be treated as Payaheads and will not be passed through until the Collection
Period in which such payments are due or until the amount of such partial
prepayment equals the amount the Obligor would be required to pay in order to
prepay the Contract in full. See "The Certificates and the Agreement -- Payahead
Account." To the extent that any Contract is prepaid in full ("Full Prepayment")
whether by the Obligor, or as the result of a purchase by the Servicer or a
repurchase by the Seller or otherwise, the actual weighted average life of the
Contracts will be shorter than a weighted average life calculation based on the
assumptions that payments will be made on schedule and that no prepayments will
be made. Weighted average life means the average amount
 
                                       22
<PAGE>   24
 
of time in which each dollar of principal on a Contract is repaid. Full
Prepayments may also result from liquidations due to default, receipt of
proceeds from theft, physical damage, credit life and credit disability
insurance policies, repurchases by the Seller as a result of the failure of a
Contract to meet certain criteria set forth in the Agreement, purchases by the
Servicer as a result of a breach of certain of its covenants with respect to the
Contracts made by it in the Agreement or as a result of an exercise by the
Servicer of its option to purchase the Trust Property. See "The Certificates and
the Agreement -- Repurchases of Contracts."
 
     In addition, the weighted average maturity of the Certificates will be
reduced to the extent that sufficient additional Motor Vehicle Contracts are not
generated for purchase by the Trust with the Pre-Funded Amount before the end of
the Funding Period, because any remaining Pre-Funded Amount will be included in
the Principal Distribution made to Certificateholders on the Distribution Date
immediately following the end of the Funding Period (or on the Distribution Date
on which the Funding Period ends if the Funding Period ends on a Distribution
Date), but in no event later than the April 15, 1997 Distribution Date.
 
     The rate of Full Prepayments by Obligors on the Contracts may be influenced
by a variety of economic, social and other factors, including the fact that an
Obligor may not sell or transfer the Financed Vehicle securing a Contract
without the consent of the Servicer. These factors may also include
unemployment, servicing decisions, seasoning of loans, destruction of vehicles
by accident, sales of vehicles and market interest rates.
 
     California, Washington and Arizona law requires that retail installment
sales contracts such as the Contracts permit full prepayment without penalty.
Any Full Prepayments reduce the average life of the Contracts. The Servicer will
permit the sale or other transfer of a Financed Vehicle without accelerating the
maturity of the related Contract if such Contract is assumed by a person
satisfying Onyx's then current underwriting standards. See "The Onyx Portfolio
of Motor Vehicle Contracts -- Underwriting of Motor Vehicle Contracts."
 
     Onyx has only 35 months of operating history and began purchasing and
originating Motor Vehicle Contracts only in February 1994. Thus, the records of
the historical prepayment experience of Onyx's Motor Vehicle Contract portfolio
are only available for such period. No assurance can be given that prepayments
on the Contracts will conform to any historical experience, and no prediction
can be made as to the actual prepayment rates which will be experienced on the
Contracts. Although Onyx believes that sufficient additional Motor Vehicle
Contracts will be originated for purchase with the Pre-Funded Amount by the end
of the Funding Period, no assurances can be given in that regard.
Certificateholders will bear all reinvestment risk resulting from the rate of
prepayment of the Contracts or the inability to purchase additional Motor
Vehicle Contracts with the Pre-Funded Amount.
 
                              YIELD CONSIDERATIONS
 
     Interest due will be passed through on each Distribution Date in an amount
equal to the product of one-twelfth of the Pass-Through Rate and the Certificate
Balance as of the close of the preceding Collection Period (or as of December
  , 1996 in the case of the first Distribution Date). In the event of a
principal prepayment on a Contract during a Collection Period,
Certificateholders will receive interest for the full month on the related
Distribution Date. See "The Certificates and the Agreement -- Distributions of
Principal and Interest."
 
     Although the Contracts have different APRs, the yield on each individual
Contract equals or exceeds      % (using the Recomputed Yield for Rule of 78's
Contracts.). Therefore, disproportionate rates of prepayments between Contracts
with higher and lower APRs will not affect the yield to Certificateholders.
 
                                  POOL FACTOR
 
     The "Pool Factor" will be a six-digit decimal which the Servicer will
compute each month indicating the Pool/Pre-Funding Balance at the end of the
month as a fraction of the original Pool/Pre-Funding Balance as of the Cut-Off
Date. The "Pool/Pre-Funding Balance" as of any date is the sum of (i) the
Aggregate Scheduled Balance of the Contracts as of such date, excluding those
Contracts which, as of such date, have
 
                                       23
<PAGE>   25
 
become Liquidated Contracts or have been purchased by the Servicer or
repurchased by the Seller and (ii) the amount on deposit in the Pre-Funding
Account (excluding any investment earnings). The Pool Factor will be 1.000000 as
of the Cut-Off Date; thereafter, the Pool Factor will decline to reflect
reductions in the Pool/Pre-Funding Balance. The amount of a Certificateholder's
pro rata share of the Pool/Pre-Funding Balance for a given month can be
determined by multiplying the original denomination of such holder's Certificate
by the Pool Factor for that month.
 
     Pursuant to the Agreement, Certificateholders will receive monthly reports
from the Trustee concerning payments received on the Contracts, the
Pool/Pre-Funding Balance, the Pool Factor, the amount remaining on deposit in
the Pre-Funding Account and various other items of information.
Certificateholders of record during any calendar year will be furnished
information for tax reporting purposes not later than the latest date permitted
by law. See "The Certificates and the Agreement."
 
                                USE OF PROCEEDS
 
     The net proceeds to be received by the Seller from the sale of Certificates
will be used to repay loans incurred pursuant to its short-term funding program
with respect to the Initial Contracts or to fund the Pre-Funded Amount to permit
the purchase of additional Motor Vehicle Contracts during the Funding Period.
 
                                   THE SELLER
 
     The Seller is a wholly-owned, limited-purpose finance subsidiary of Onyx
which was incorporated under the laws of the State of Delaware on July 28, 1994
and has a limited operating history. The principal office of the Seller is
located at 8001 Irvine Center Drive, 5th Floor, Irvine, CA 92718. The telephone
number of such office is (714) 753-1191.
 
     The Seller was organized principally for the purpose of purchasing retail
installment sales contracts from Onyx in connection with its activities as a
finance subsidiary of Onyx. The Seller was organized for limited purposes, and
its certificate of incorporation limits its activities to purchasing Contracts
from Onyx and transferring such Contracts to third parties and any activities
incidental to and necessary or convenient for the accomplishment of such
purposes.
 
     The Seller has taken steps in structuring the transactions contemplated
hereby that are intended to ensure that the voluntary or involuntary application
for relief by Onyx under any Insolvency Law will not result in consolidation of
the assets and liabilities of the Seller with those of Onyx. These steps include
the creation of the Seller as a separate, limited-purpose subsidiary pursuant to
a certificate of incorporation containing certain limitations (including
restrictions on the nature of the Seller's business and a restriction on the
Seller's ability to commence a voluntary case or proceeding under any Insolvency
Law without the unanimous affirmative vote of all of its directors). However,
there can be no assurance that the activities of the Seller would not result in
a court concluding that the assets and liabilities of the Seller should be
consolidated with those of Onyx in a proceeding under any Insolvency Law.
 
     The Seller has received the advice of counsel to the effect that, subject
to certain facts, assumptions and qualifications, it would not be a proper
exercise by a court of its equitable discretion to disregard the separate
corporate existence of the Seller and to require the consolidation of the assets
and liabilities of the Seller with the assets and liabilities of Onyx in the
event of the application of the federal bankruptcy laws to Onyx. Among other
things, it is assumed by counsel that the Seller will follow certain procedures
in the conduct of its affairs, including maintaining records and books of
account separate from those of Onyx, refraining from commingling its assets with
those of Onyx and refraining from holding itself out as having agreed to pay, or
being liable for, the debts of Onyx. The Seller intends to follow and has
represented to such counsel that it will follow these and other procedures
related to maintaining its separate corporate identity. However, there can be no
assurance that a court would not conclude that the assets and liabilities of the
Seller should be consolidated with those of Onyx. If a court were to reach such
a conclusion, or a filing were made under any Insolvency Law by or against the
Seller, or if an attempt were made to litigate any of the foregoing issues,
delays in distributions on the Certificates could occur or reductions in the
amounts of such distributions could result.
 
                                       24
<PAGE>   26
 
     The Contracts have been and will be sold by Onyx to the Seller from time to
time pursuant to a Sale and Servicing Agreement dated as of September 8, 1994
(the "Purchase Agreement"). The Initial Contracts were sold and the Subsequent
Contracts will be sold by the Seller to the Trust pursuant to the Agreement.
Onyx and the Seller intend that the transfer of the Contracts by Onyx to the
Seller under the Purchase Agreement constitute a "true sale" of the Contracts to
the Seller. If the transfer constitutes such a "true sale," the Contracts and
the proceeds thereof would not be part of the bankruptcy estate of Onyx under
Section 541 of the Bankruptcy Code should Onyx become the subject of a
bankruptcy case subsequent to the transfer of the Contracts to the Seller.
 
     The Seller has received the advice of counsel to the effect that, subject
to certain facts, assumptions and qualifications, in the event Onyx were to
become the subject of a voluntary or involuntary case under the Bankruptcy Code
subsequent to the transfer of the Contracts to the Seller, the transfer of the
Contracts by Onyx to the Seller pursuant to the Purchase Agreement would be
characterized as a "true sale" of the Contracts from Onyx to the Seller and the
Contracts and the proceeds thereof would not form part of Onyx's bankruptcy
estate pursuant to Section 541 of the Bankruptcy Code.
 
     In Octagon Gas Systems, Inc. v. Rimmer, 995 F.2d 948 (10th Cir. 1993) cert.
denied, 114 S. Ct. 554 (1993), the United States Court of Appeals for the 10th
Circuit suggested that even where a transfer of accounts from a seller to a
buyer constitutes a "true sale," the accounts would nevertheless constitute
property of the seller's bankruptcy estate in a bankruptcy of the seller. If
Onyx or the Seller were to become subject to a bankruptcy proceeding and a court
were to follow the Octagon Gas court's reasoning, Certificateholders might
experience delays in payment or possibly losses on their investment in the
Certificates. As part of the advice of counsel described above, counsel has
advised the Seller that the reasoning of the Octagon Gas case appears to be
inconsistent with precedent and the Uniform Commercial Code. As the Octagon case
indicates, however, a court may reach a different conclusion with respect to
these or similar matters.
 
                                  THE SERVICER
 
     The Contracts will be serviced by Onyx Acceptance Corporation ("Onyx").
Onyx was incorporated in California in 1993 and reincorporated in Delaware in
1996 in connection with its initial public offering of Common Stock which was
successfully completed in March 1996 and all stock offered in connection with
such public offering was sold. Onyx is engaged principally in the business of
providing indirect automobile financing to new car dealerships and selected used
car dealerships within California, and to an increasing degree in other Western
states. Onyx has been in existence for nearly three years and is headed by a
management team with extensive experience in the origination and servicing of
indirect and direct automobile loans (average tenure of 14 years), and who, from
1985 to present, have actively participated in a number of public
securitizations of motor vehicle installment contracts.
 
   
     Onyx is headquartered in Irvine, California and operates eight Auto Finance
Centers, six in California and one in each of Arizona and Washington. The
California centers are located in: (i) Orange and Metropolitan Los Angeles
Counties, (ii) North Los Angeles and Ventura Counties, (iii) the San Francisco
Bay Area, (iv) Riverside and San Bernardino Counties, (v) San Diego County, and
(vi) Sacramento County. Through these offices, Onyx is able to service the most
populous California counties including Los Angeles, Riverside, San Bernardino,
Ventura, Orange, San Diego, San Francisco, Santa Clara, Alameda, San Mateo,
Santa Cruz, Marin, Contra Costa, and Sacramento counties. In addition, Onyx
services Hawaii and Nevada through its California centers. The Arizona center is
located in Phoenix, and is able to service the Phoenix metropolitan and suburban
areas. The Washington center is located in Seattle and is able to service the
Seattle metropolitan and suburban areas. Onyx currently has agreements with
1,373 Dealers.
    
 
     Onyx acquires individual motor vehicle installment contracts from Dealers
after reviewing and approving the customer's credit application in accordance
with its underwriting policies and procedures. See "The Contracts." Onyx
acquired motor vehicle installment contracts totaling approximately $521.9
million from commencement of operations through September 30, 1996. As of
September 30, 1996, Onyx has amassed a servicing portfolio of approximately $359
million. As of September 30, 1996, approximately 77.7% of Onyx's servicing
portfolio consisted of motor vehicle installment contracts secured by used motor
vehicles, and 22.3%
 
                                       25
<PAGE>   27
 
secured by new motor vehicles. As of September 30, 1996, Onyx had total assets
of approximately $69.2 million and shareholders equity of $36.9 million.
 
     Onyx finances its acquisition of motor vehicle installment contracts on a
short term basis through a commercial paper conduit program and has previously
financed its acquisition of motor vehicle installment contracts on a long term
basis through sales of Contracts to grantor trusts.
 
                       THE CERTIFICATES AND THE AGREEMENT
 
     The Certificates will be issued pursuant to the Agreement, a form of which
has been filed as an exhibit to the Registration Statement of which this
Prospectus is a part. The following summaries of certain provisions of the
Agreement do not purport to be complete and are subject to, and qualified in
their entirety by reference to, the provisions of the Agreement. Where
particular provisions of or terms used in the Agreement are referred to, the
actual provisions (including definitions of terms) are incorporated by reference
as part of such summaries.
 
GENERAL
 
     The Certificates will be offered for purchase in minimum denominations of
$1,000 and integral multiples thereof, except that one Certificate may be issued
in a denomination that includes any residual portion of the Pool/Pre-Funding
Balance as of the Cut-Off Date. Each Certificate will rank pari passu with each
other Certificate. The Certificates will initially be represented by one or more
Certificates registered in the name of the nominee of DTC except as set forth
below. The interests of holders of beneficial interests in the Certificates
(each a "Certificate Owner") will be available for purchase in denominations of
$1,000 and integral multiples thereof in book-entry form only. The Seller has
been informed by DTC that DTC's nominee will be Cede. Accordingly, Cede is
expected to be the holder of record of the Certificates. Unless and until
Definitive Certificates are issued under the limited circumstances described
herein, no Certificate Owner will be entitled to receive a certificate
representing such person's interest in the Certificates. All references herein
to actions by Certificateholders shall refer to actions taken by DTC upon
instructions from its participating organizations (the "Participants") and all
references herein to distributions, notices, reports and statements to
Certificateholders shall refer to distributions, notices, reports and statements
to DTC or Cede, as the registered holder of the Certificates, as the case may
be, for distribution to Certificate Owners in accordance with DTC procedures.
See "The Certificates and the Agreement -- Book-Entry Registration" and
"-- Definitive Certificates."
 
DISTRIBUTIONS OF PRINCIPAL AND INTEREST
 
   
     On each Distribution Date, monthly interest due on the Contracts (the
"Interest Distribution") at a rate equal to the product of one-twelfth of the
Pass-Through Rate and the Certificate Balance as of the close of the related
Collection Period will be distributed to the Certificateholders of record on a
pro rata basis as of the immediately preceding Record Date (defined below). The
Certificate Balance will initially equal $100,000,000 (the "Original Certificate
Balance") and as of any Distribution Date will equal the Original Certificate
Balance, reduced by all previous Principal Distributions, including any amounts
from the Pre-Funding Account which are distributed on the Distribution Date
immediately following the end of the Funding Period. Interest will be paid (i)
to the extent of the portion of the Certificate Balance related to Contracts,
from collections received on the Contracts on deposit in the Collection Account
or previously collected and available for distribution, and (ii) to the extent
of the portion of the Certificate Balance related to the Pre-Funding Account
from investment earnings thereon and from payments under the Yield Supplement
Agreement. A "Collection Period" with respect to a Distribution Date will be the
calendar month preceding the month in which such Distribution Date occurs;
provided, that with respect to Liquidated Contracts (as defined below) the
Collection Period will be the period from but excluding the sixth Business Day
preceding the immediately preceding Distribution Date to and including the sixth
Business Day preceding such Distribution Date. With respect to the first
Distribution Date the "Collection Period" for Liquidated Contracts will be the
period from and including the Cut-Off Date to and including the sixth Business
Day
    
 
                                       26
<PAGE>   28
 
preceding such first Distribution Date. Each Interest Distribution will be
calculated on the basis of a 360-day year consisting of twelve 30-day months.
Unless Definitive Certificates have been issued, distributions on each
Distribution Date will be made through the facilities of DTC and will be payable
to Certificateholders registered as such on the Business Day prior to such
Distribution Date (or, if Definitive Certificates are issued, the last day of
the calendar month preceding such Distribution Date) (the "Record Date"), except
that the final distribution of principal of and interest on each Certificate
will be made only upon presentation and surrender of such Certificate on or
after the Final Scheduled Distribution Date (or such earlier termination date as
is provided by the Agreement) at the office or agency of the Trustee maintained
for that purpose.
 
     On each Distribution Date, Principal Distributions for the related
Collection Period will be passed through to the Certificateholders. The
"Principal Distribution" on any Distribution Date will be an amount equal to the
Aggregate Scheduled Balance Decline during the related Collection Period and,
with respect to the Distribution Date immediately following the last day of the
Funding Period, any portion of the Pre-Funded Amount remaining on deposit in the
Pre-Funding Account. The Principal Distribution on the Final Distribution Date
will include the Aggregate Scheduled Balance of all Contracts that are
outstanding at the end of the Collection Period immediately prior to the Final
Distribution Date. The "Aggregate Scheduled Balance Decline" for any
Distribution Date will be the sum of (x) the amount by which the Aggregate
Scheduled Balance of the Contracts as of the beginning of the related Collection
Period exceeds the Aggregate Scheduled Balance of such Contracts as of the end
of the related Collection Period (excluding any Contracts added as Subsequent
Contracts during the related Collection Period) and (y) the amount by which the
Aggregate Scheduled Balance of the Subsequent Contracts (determined as of each
related Subsequent Transfer Date) transferred to the Trust during the related
Collection Period exceeds the Aggregate Scheduled Balance of such Contracts as
of the end of the related Collection Period. The "Aggregate Scheduled Balance"
of the Contracts is the sum of the Scheduled Balances of each Contract. The
"Scheduled Balance" of a Rule of 78's Contract at any date is equal to the
Cut-Off Date Scheduled Balance of such Contract reduced by the portion of each
scheduled payment of principal and interest due on such Contract (the "Monthly
P&I") on or prior to the date of calculation that is allocable to principal
under the Recomputed Actuarial Method. The Scheduled Balance of a Simple
Interest Contract at any date is equal to the Cut-Off Date Scheduled Balance of
such Contract reduced by the portion of Monthly P&I on or prior to the date of
calculation that is allocated to principal under the Simple Interest Method. The
Scheduled Balance of any Contract that is a Liquidated Contract or that has been
purchased by the Servicer or repurchased by the Seller will equal zero. A
"Liquidated Contract" is a Contract that (a) is the subject of a Full
Prepayment, (b) is a Defaulted Contract with respect to which Liquidation
Proceeds constituting, in the Servicer's reasonable judgment, the final amounts
recoverable have been received, (c) is paid in full on or after its Maturity
Date or (d) has been a Defaulted Contract for four or more Collection Periods
and as to which Liquidation Proceeds constituting the final amounts recoverable
have not been received; provided, however, that in any event a Contract that is
delinquent in the amount of five monthly payments at the end of a Collection
Period is a Liquidated Contract. A "Defaulted Contract" with respect to any
Collection Period is a Contract (a) which is, at the end of such Collection
Period, delinquent in the amount of two monthly payments or (b) with respect to
which the related Financed Vehicle has been repossessed or repossession efforts
have been commenced.
 
     The Monthly P&I for a Contract due on each Due Date is substantially equal
for the term of the Contract. The Scheduled Balance of each Initial Contract as
of the Cut-Off Date, which will be treated as being equal to the Cut-Off Date
Scheduled Balance, will be set forth in a schedule to the Agreement. The yield
of each Contract will at least equal      % (using the Recomputed Yield for Rule
of 78's Contracts).
 
     At the issuance of the Certificates, the Original Certificate Balance will
equal the sum of the Aggregate Scheduled Balance of all the Initial Contracts
and the Pre-Funded Amount.
 
   
THE PRE-FUNDING ACCOUNT; MANDATORY PARTIAL PREPAYMENT OF THE CERTIFICATES
    
 
   
     The Pre-Funding Account.  The Servicer will establish an account in the
name of the Trustee for the benefit of the Certificateholders into which the
Pre-Funded Amount (which equals $24,067,029, or approximately 24% of the Initial
Certificate Balance) will be deposited on the Closing Date from the net proceeds
received from the sale of the Certificates and from which monies will be
released during the Funding
    
 
                                       27
<PAGE>   29
 
   
Period to purchase Subsequent Contracts from the Seller (the "Pre-Funding
Account"). The Funding Period will be the period from the Closing Date until the
earliest to occur of (i) the date on which the Pre-Funded Amount is less than
$20,000, (ii) the date on which an Event of Default occurs, or (iii) the close
of business on March   , 1997. The Pre-Funding Account will be an Eligible
Account. An "Eligible Account" is (i) a trust account that is either (a)
maintained by the Trustee, (b) maintained with a depository institution or trust
company the commercial paper or other short-term debt obligations of which have
credit ratings from Standard & Poor's at least equal to "A-1" and from Moody's
equal to "P-1," which account is fully insured up to applicable limits by the
Federal Deposit Insurance Corporation or (c) maintained with a depository
institution acceptable to the Insurer or (ii) a general ledger account or
deposit account at a depository institution acceptable to the Insurer. The
Pre-Funding Account will be part of the Trust but monies on deposit therein will
not be available to cover losses on or in respect of the Contracts. Any portion
of the Pre-Funded Amount remaining on deposit in the Pre-Funding Account as of
the end of the Funding Period will be payable as described below as prepayment
of principal to the Certificateholders. Monies on deposit in the Pre-Funding
Account may be invested in Eligible Investments under the circumstances and in
the manner described in the Agreement. Earnings on investment of funds in the
Pre-Funding Account will be used, together with the Yield Supplement Amount paid
under the Yield Supplement Agreement, to pay the Pass-Through Rate on the
portion of the Certificate Balance relating to the Pre-Funding Account. The
Trust will not be required to register under the Investment Company Act of 1940.
    
 
     Upon each conveyance of Subsequent Contracts on each Subsequent Transfer
Date to the Trust, an amount equal to the purchase price paid by the Seller to
Onyx for such Subsequent Contracts on the related Subsequent Transfer Date will
be released from the Pre-Funding Account and paid to the Seller.
 
   
     Mandatory Partial Prepayment of the Certificates.  The Certificates will be
subject to partial Mandatory Partial Prepayment on the Distribution Date
immediately succeeding the date on which the Funding Period ends (or on the
Distribution Date on which the Funding Period ends if the Funding Period ends on
a Distribution Date), to the extent that any portion of the Pre-Funded Amount,
exclusive of any investment earnings thereon, remains on deposit in the
Pre-Funding Account after giving effect to the purchase by the Seller and
conveyance to the Trust of any Subsequent Contracts on the related Subsequent
Transfer Dates, including any such purchase and conveyance on the date on which
the Funding Period ends.
    
 
   
     Upon the occurrence of a Mandatory Partial Prepayment, the holders of
Certificates will receive an amount equal to the portion of the Pre-Funded
Amount remaining in the Pre-Funding Account. It is anticipated that the
aggregate principal amount of Subsequent Contracts purchased by the Trust and
delivered to the Trustee during the Funding Period will not be exactly equal to
the Pre-Funded Amount and that therefore there will be at least a nominal amount
of principal prepaid to Certificateholders.
    
 
YIELD SUPPLEMENT AGREEMENT AND YIELD SUPPLEMENT RESERVE ACCOUNT
 
   
     Simultaneously with the sale and assignment of the Contracts by the Seller
to the Trust, Onyx and the Seller will enter into the Yield Supplement
Agreement, pursuant to which Onyx will be obligated to pay the Yield Supplement
Amount, if any, on or before five Business Days prior to each Distribution Date,
ending with the Distribution Date following the end of the Funding Period. The
Seller will assign its rights under the Yield Supplement Agreement to the Trust.
Payments of the Yield Supplement Amounts due under the Yield Supplement
Agreement will be secured by funds on deposit in a segregated trust deposit
account (the "Yield Supplement Reserve Account") established in the name of
Bankers Trust Company, acting as agent for the benefit of the Certificateholders
and the Insurer (in such capacity, the "Yield Supplement Agent"). The Yield
Supplement Reserve Account will be an Eligible Account. The amount required to
be deposited in such Yield Supplement Reserve Account on the Closing Date will
be the maximum aggregate Yield Supplement Amounts that may become owing under
the Yield Supplement Agreement, assuming that, with respect to the Pre-Funded
Amount during the Funding Period, no Subsequent Contracts are acquired. The
"Yield Supplement Amount," with respect to any Distribution Date for any
Collection Period up through the last Collection Period in the Funding Period,
is an amount equal to the difference between (a) one month's interest on the
Pre-Funded Amount on deposit in the Pre-Funding Account as of the first day of
such Collection Period at the Pass-Through Rate and (b) the earnings received by
the Trustee during the related
    
 
                                       28
<PAGE>   30
 
   
Collection Period from investment of the Pre-Funded Amount on deposit in the
Pre-Funding Account. On each Subsequent Closing Date, an amount will be released
to Onyx from the Yield Supplement Reserve Account so that the amount remaining
in the account after such release will equal the maximum Yield Supplement Amount
which could become owing during the remainder of the Funding Period assuming
that no additional Subsequent Contracts are conveyed to the Trust. Any amounts
remaining on deposit in the Yield Supplement Reserve Account after the Mandatory
Partial Prepayment of that portion of the Pre-Funded Amount not used to purchase
Subsequent Contracts will be released to Onyx on the date of such Mandatory
Partial Prepayment.
    
 
THE SURETY BOND
 
     If on any Servicer Report Date the amount on deposit in the Collection
Account after giving effect to all amounts deposited to or payable from the
Pre-Funding Account and the Payahead Account with respect to the related
Distribution Date, is less than the sum of the Servicing Fee, the Principal
Distribution and Interest Distribution for the related Distribution Date, the
Trustee by delivering a notice to the Insurer shall demand payment under the
Surety Bond in an amount equal to such deficiency. The Insurer shall pay or
cause to be paid such amount to the Trustee for credit to the Collection
Account. The Trustee shall withdraw from the Collection Account and shall pay
such amount to the Certificateholders on the related Distribution Date.
 
     If on the Business Day preceding the Final Distribution Date, any principal
amount of Certificates is still outstanding, then the Trustee shall demand
payment on the Surety Bond in an amount equal to the amount by which the
outstanding principal amount of the Certificates, plus interest thereon at the
Pass-Through Rate, exceeds the amount on deposit in the Collection Account which
is available for distribution on the Final Distribution Date. The Insurer shall
pay or cause to be paid such amount to the Trustee pursuant to the Trustee's
instructions for credit to the Collection Account and on the Final Scheduled
Distribution Date, the Trustee shall withdraw from the Collection Account and
shall pay such amount to the Certificateholders.
 
BOOK-ENTRY REGISTRATION
 
     Certificateholders may hold their Certificates through DTC if they are
participants of such system, or indirectly through organizations which are
participants ("Participants") in such system.
 
     Cede, as nominee for DTC, will hold one or more global Certificates.
Transfers between Participants will occur in the ordinary way in accordance with
DTC rules.
 
     DTC is a limited-purpose trust company organized under the laws of the
State of New York, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the New York UCC, and a "clearing agency"
registered pursuant to the provisions of Section 17A of the Exchange Act. DTC
was created to hold securities for its Participants and facilitate the clearance
and settlement of securities transactions between Participants through
electronic book-entry changes in accounts of its Participants, thereby
eliminating the need for physical movement of certificates. Participants include
securities brokers and dealers, banks, trust companies and clearing corporations
and may include certain other organizations (including the Underwriters).
Indirect access to the DTC system also is available to others such as banks,
brokers, dealers and trust companies that clear through or maintain a custodial
relationship with a Participant, either directly or indirectly (the "Indirect
Participants").
 
     Certificate Owners that are not Participants or Indirect Participants but
desire to purchase, sell or otherwise transfer ownership of, or other interests
in, Certificates may do so only through Participants and Indirect Participants.
In addition, Certificateholders will receive all distributions of principal of
and interest on the Certificates from the Trustee, as paying agent, or its
successor in such capacity (the "Paying Agent"), through the Participants who in
turn will receive them from DTC. Under a book-entry format, Certificate Owners
may experience some delay in their receipt of payments, since such payments will
be forwarded by the Paying Agent to Cede, as nominee for DTC. DTC will forward
such payments to its Participants which thereafter will forward them to Indirect
Participants or Certificate Owners. It is anticipated that the only
"Certificateholder" will be Cede, as nominee of DTC. Certificate Owners will not
be recognized by the Trustee as Certificateholders, as such term is used in the
Agreement, and Certificate Owners will only be
 
                                       29
<PAGE>   31
 
permitted to exercise the rights of Certificateholders indirectly through the
Participants who in turn will exercise the rights of Certificateholders through
DTC.
 
     Under the rules, regulations and procedures creating and affecting DTC and
its operations, DTC is required to make book-entry transfers among Participants
on whose behalf it acts with respect to the Certificates and is required to
receive and transmit distributions of principal of and interest on the
Certificates. Participants and Indirect Participants with which Certificate
Owners have accounts with respect to the Certificates similarly are required to
make book-entry transfers and receive and transmit such payments on behalf of
their respective Certificate Owners. Accordingly, although Certificate Owners
will not possess Certificates, Certificate Owners will receive payments and will
be able to transfer their interests.
 
     Because DTC can only act on behalf of Participants, who in turn act on
behalf of Indirect Participants and certain banks, the ability of a Certificate
Owner to pledge Certificates to persons or entities that do not participate in
the DTC system, or otherwise take actions in respect of such Certificates, may
be limited due to the lack of a physical certificate for such Certificates.
 
     DTC has advised the Seller that it will take any action permitted to be
taken by a Certificateholder under the Agreement only at the direction of one or
more Participants to whose account with DTC the Certificates are credited.
Additionally, DTC has advised the Seller that it will take such actions with
respect to the particular portion of the Certificates represented by the
undivided interests held by Participants which have directed DTC, on their
behalf, to take such action. DTC may take conflicting actions with respect to
other undivided interests to the extent that such actions are taken on behalf of
Participants whose holdings include such undivided interests.
 
     Although DTC has agreed to the foregoing procedures in order to facilitate
transfers of Certificates among participants of DTC, they are under no
obligation to perform or continue to perform such procedures and such procedures
may be discontinued at any time.
 
DEFINITIVE CERTIFICATES
 
     The Certificates will be issued in fully registered, certificated form in
denominations of $1,000 and integral multiples thereof to Certificate Owners or
their nominees (the "Definitive Certificates"), rather than to DTC or its
nominee, only if (i) the Seller advises the Trustee in writing that DTC is no
longer willing or able to discharge properly its responsibilities as depositary
with respect to the Certificates, and the Trustee or the Seller are unable to
locate a qualified successor, or (ii) after the occurrence of an Event of
Default, Certificate Owners representing in the aggregate more than 50% of the
Pool/Pre-Funding Balance advise the Trustee and DTC through Participants in
writing that the continuation of a book-entry system with respect to the
Certificates through any depositary is no longer in the best interest of the
Certificate Owners.
 
     Upon the occurrence of any of the events described in the immediately
preceding paragraph, DTC is required to notify all Participants of the
availability through DTC of Definitive Certificates. Upon surrender by DTC of
the Definitive Certificates representing the Certificates and instructions for
reregistration, the Trustee will issue the Certificates as Definitive
Certificates, and thereafter the Trustee will recognize the holders of such
Definitive Certificates as holders under the Agreement (collectively,
"Holders").
 
     Distribution of principal of and interest on the Certificates will be made
by the Paying Agent directly to Holders of Definitive Certificates in accordance
with the procedures set forth herein and in the Agreement. Interest
Distributions and Principal Distributions on each Distribution Date and on the
Final Distribution Date will be made to Holders in whose names the Definitive
Certificates were registered at the close of business on the related Record
Date. Distributions will be made by check mailed to the address of such Holder
as it appears on the certificate register. The final payment of any Certificate
(whether Definitive Certificates or the Certificate registered in the name of
DTC's nominee), however, will be made only upon presentation and surrender of
such Certificate at the office or agency specified in the notice of final
distribution to Certificateholders. The Trustee will provide such notice to
registered Certificateholders not later than the fifteenth day of the month of
such final distribution.
 
                                       30
<PAGE>   32
 
     Definitive Certificates will be transferable and exchangeable at the
offices of the Transfer Agent and Registrar, which shall initially be the
Trustee. No service charge will be imposed for any registration of transfer or
exchange, but the Transfer Agent and Registrar may require payment of a sum
sufficient to cover any tax or other governmental charge imposed in connection
therewith.
 
SALE AND ASSIGNMENT OF THE CONTRACTS
 
     At the time of issuance of the Certificates, the Seller will sell and
assign to the Trustee, without recourse, the Seller's entire interest in the
Initial Contracts and the proceeds thereof, including its security interests in
the Initial Financed Vehicles. Concurrently with the sale and assignment of the
Initial Contracts, the Seller will sell and assign to the Trustee, against
payment therefor from the Pre-Funded Amount, all of the Seller's interest in the
Subsequent Contracts thereafter created and delivered to the Trustee. Each
Initial Contract will be identified in a schedule appearing as an exhibit to the
Agreement. The Trustee will, concurrently with such sale and assignment,
execute, authenticate and deliver the definitive certificates representing the
Certificates to the Underwriter against payment to the Seller of the net
purchase price of the sale of the Certificates. Pursuant to the Purchase
Agreement, prior to sale of the Initial Contracts to the Trustee and the
issuance of the Certificates, Onyx sold and assigned to the Seller Onyx's entire
interest in the Initial Contracts.
 
     During the Funding Period, pursuant to the Purchase Agreement, Onyx will be
obligated to sell and the Seller will be obligated to purchase, Subsequent
Contracts. On each Subsequent Transfer Date, Onyx will sell and assign to the
Seller, without recourse, its entire right, title and interest in and to
Subsequent Contracts, including its security interest in the Subsequent Financed
Vehicles. The purchase price to be paid to Onyx for each Subsequent Contract
will equal the principal balance thereof as of the related Subsequent Transfer
Date. Pursuant to the Agreement, the Seller will in turn sell the Subsequent
Contracts to the Trust. Each Subsequent Contract will be sold to the Trust
within two Business Days of its acquisition by Onyx. In connection with each
purchase of Subsequent Contracts, the Trust will be required to pay to the
Seller an amount equal to the amount paid by the Seller to Onyx for such
Subsequent Contracts, which purchase price will be paid from monies on deposit
in the Pre-Funding Account. Each Subsequent Contract delivered to the Trustee on
each Subsequent Transfer Date will be accompanied by a certificate of the Seller
(a "Transfer Certificate") setting forth the aggregate principal balance of the
related Subsequent Contracts, the aggregate principal balance of the Subsequent
Contracts delivered to the Trustee during the Funding Period up to and including
such Subsequent Transfer Date and an affirmation of the representations and
warranties set forth in the Agreement with respect to the Seller and such
Subsequent Contracts. Upon the conveyance of Subsequent Contracts to the Trust
on a Subsequent Transfer Date, the Pool Balance will increase in an amount equal
to the aggregate Cut-Off Date Scheduled Balance of such Subsequent Contracts as
of the related Subsequent Transfer Date.
 
     Each conveyance of Subsequent Contracts will be subject to the following
conditions, among others: (i) such Subsequent Contracts must satisfy the
Eligibility Requirements; (ii) such Subsequent Contracts were not selected by
Onyx or the Seller in a manner that either believes is adverse to the interests
of the Certificateholders or the Insurer; (iii) the weighted average APR of the
Contracts (after giving effect to the purchase of the related Subsequent
Contracts) is not less than      %; (iv) the weighted average remaining term of
the Contracts (including the Subsequent Contracts) as of the related Subsequent
Transfer Date will not be greater than 72 months; and (v) the Seller and the
Trustee shall not have been advised by either Rating Agency that the conveyance
of such Subsequent Contracts will result in a qualification, modification or
withdrawal of its then current rating of the Certificates.
 
     On the Business Day preceding each Distribution Date during and immediately
following the Funding Period (each such date a "Subsequent Closing Date") UCC-1
financing statements will be filed naming the Seller as seller and the Trustee
as the purchaser with respect to the Subsequent Contracts delivered to the
Trustee since the preceding Subsequent Closing Date (or the Closing Date, in the
case of the first Subsequent Closing Date) and all legal opinions, officers'
certificates and other documentation necessary with respect to the Subsequent
Contracts delivered to the Trustee since the preceding Subsequent Closing Date
(or the Closing Date, as the case may be) will be executed and delivered.
Failure to comply with any of the conditions set forth in the Agreement with
respect to a Subsequent Closing Date will be deemed to be a breach of a
representation and warranty with respect to the Subsequent Contracts to which
such Subsequent Closing Date
 
                                       31
<PAGE>   33
 
relates and accordingly the Seller will be obligated to repurchase such
Subsequent Contracts from the Trust as described below.
 
     Because the Subsequent Contracts will be originated after the Initial
Contracts, following their conveyance to the Trust, the characteristics of the
Contracts, including the Subsequent Contracts, may vary from those of the
Initial Contracts.
 
     Pursuant to the Agreement, the Seller will represent to the Trustee and the
Trust for the benefit of holders of the Certificates and the Insurer that: (i)
each Contract contains customary and enforceable provisions such that the rights
and remedies of the holder thereof shall be adequate for realization against the
collateral of the benefits of the security; (ii) each Contract and the sale of
the related Financed Vehicle complied at the time it was made in all material
respects with all requirements of applicable federal, state, and local laws, and
regulations thereunder, including usury laws, the Federal Truth-in-Lending Act,
the Equal Credit Opportunity Act, the Fair Credit Reporting Act, the Federal
Trade Commission Act, state adaptations of the National Consumer Act and of the
Uniform Consumer Credit Code, and any other consumer credit, equal opportunity
and disclosure laws applicable to such Contract and sale; (iii) each Contract
constitutes the legal, valid, and binding payment obligation in writing of the
Obligor, enforceable by the holder thereof in all respects in accordance with
its terms, subject, as to enforcement, to applicable bankruptcy, insolvency,
reorganization, liquidation and other similar laws and equitable principles
relating to or affecting the enforcement of creditors' rights; (iv) immediately
prior to the sale and assignment thereof to the Trust, each Contract was secured
by a validly perfected first priority security interest in the Financed Vehicle
in favor of the Seller as secured party or all necessary action with respect to
such Contract has been taken to perfect a first priority security interest in
the related Financed Vehicle in favor of the Seller as secured party, which
security interest is assignable and has been so assigned by the Seller to the
Trust; (v) as of the Cut-Off Date in the case of the Initial Contracts and each
Subsequent Transfer Date in the case of each Subsequent Contract, the Seller had
good and marketable title to and was the sole owner of each Contract, free of
liens, claims, encumbrances and rights of others; (vi) as of the Closing Date in
the case of the Initial Contracts and each Subsequent Transfer Date in the case
of the Subsequent Contracts, there are no rights of rescission, offset,
counterclaim, or defense, and the Seller has no knowledge of the same being
asserted or threatened, with respect to any Contract; (vii) as of the Closing
Date in the case of the Initial Contracts and each Subsequent Transfer Date in
the case of the Subsequent Contracts, the Seller had no knowledge of any liens
or claims that have been filed, including liens for work, labor, materials or
unpaid taxes relating to a Financed Vehicle, that would be liens prior to, or
equal or coordinate with, the lien granted by the Contract; (viii) except for
payment defaults continuing for a period of not more than 30 days as of the
Cut-Off Date in the case of the Initial Contracts, and each Subsequent Transfer
Date in the case of Subsequent Contracts, the Seller has no knowledge that a
default, breach, violation, or event permitting acceleration under the terms of
any Contract exists, and the Seller has no knowledge that a continuing condition
that with notice or lapse of time would constitute a default, breach, violation
or event permitting acceleration under the terms of any Contract exists, and the
Seller has not waived any of the foregoing; (ix) each Contract requires that the
Obligor thereunder obtain comprehensive and collision insurance covering the
Financed Vehicle; (x) each Contract was acquired from a dealer with whom Onyx
ordinarily does business (except for Contracts originated by Onyx); (xi) no
adverse selection procedures were utilized in selecting the Contracts; (xii)
scheduled payments under each Contract have been applied in accordance with the
method for allocating principal and interest set forth in the Contract (either
the Rule of 78's or Simple Interest Method) and (xiii) there is only one
original of each Contract and such original is being held by the Trustee as
custodian on behalf of the Trust and Insurer. As of the last day of the
Collection Period following the Collection Period (or, if the Seller elects, the
last day of such Collection Period) during which the Seller becomes aware or
receives written notice from the Trustee or the Servicer that a Contract does
not meet any of the criteria in the Agreement and such failure materially and
adversely affects the interests of the Certificateholders or the Insurer in a
Contract, the Seller, unless it cures the failed criterion, will repurchase the
Contract from the Trustee at a price equal to the Scheduled Balance thereof plus
accrued interest (the "Repurchase Amount"). The repurchase obligation will
constitute the sole remedy available to the Certificateholders or the Trustee
for the failure of a Contract to meet any of the criteria set forth in the
Agreement.

THE COLLECTION ACCOUNT AND ELIGIBLE INVESTMENTS
 
     The Servicer will cause all collections made on the Contracts during a
Collection Period to be deposited in or credited to an account (the "Collection
Account") established by the Servicer under the Agreement. Funds in the
Collection Account will be invested in Eligible Investments by the Trustee
acting at the direction of the Insurer. "Eligible Investments" are (a) direct
obligations issued or fully guaranteed by the United States or any agency or
instrumentality of the United States whose obligations are backed by the full
faith and credit of the United States and, to the extent, at the time of the
investment, acceptable to the Insurer and each statistical rating agency rating
the Certificates for securities having a rating equivalent to the rating of the
Certificates at the Closing Date, the direct obligations of, or obligations
fully guaranteed by, the Federal Home Loan Mortgage Corporation and the Federal
National Mortgage Association; (b) deposits in or other obligations of any bank
(including the Trustee) whose long-term unsecured debt obligations are rated
"AA-" or better by Standard & Poor's Ratings Services ("Standard & Poor's") and
"Aa2" or better by Moody's Investors Service, Inc. ("Moody's") or any bank
acceptable to the Insurer; (c) repurchase obligations with respect to federal
government or agency securities described in clause (a) above entered into with
any bank described in clause (b) above; (d) interest-bearing or discount
corporate securities rated "AA-" or better by Standard & Poor's and "Aa2" or
better by Moody's; (e) commercial paper having the highest rating obtainable
from Standard & Poor's and Moody's; (f) investments in money market funds or
money market mutual funds having a rating from Standard & Poor's and Moody's in
the highest investment category granted thereby, including funds for which the
Trustee or any of its affiliates is investment manager or advisor; and (g) such
other securities that are acceptable to the Insurer. Eligible Investments made
with respect to the Collection Account will mature no later than the next
following Distribution Date. Income from amounts on deposit in the Collection
Account which are invested in Eligible Investments will be paid to the Servicer
monthly unless earlier directed by the Servicer.
 
PAYAHEAD ACCOUNT
 
     For Simple Interest Contracts, payments made by an Obligor in excess of the
Monthly P&I due on the current Due Date and any other amount currently due on a
Contract (including Full Prepayments) will be passed through to the
Certificateholders on the Distribution Date immediately following the Collection
Period in which such payment was collected.
 
     For Rule of 78's Contracts, however, payments made by an Obligor in excess
of the Monthly P&I due on the current Due Date and any other amount currently
due on a Contract (other than Full Prepayments) ("Payaheads") will be initially
deposited in the Collection Account and subsequently transferred from the
Collection Account, as of each Servicer Report Date, to an account established
in the name of Bankers Trust Company for the benefit of the Obligors and the
Certificateholders as their interests may appear (the "Payahead Account") and
shall be held in such account until passed through in accordance with the
original schedule of payments for the related Contract or until the amount of
such partial prepayment equals the amount the Obligor would be required to pay
in order to prepay the Contract in full. The Payahead Account will be an
Eligible Account. Amounts on deposit in the Payahead Account will be invested in
Eligible Investments with maturity dates such that on each Distribution Date
Monthly P&I for each Rule of 78's Contract with respect to which a partial
prepayment had been made will be available to be passed through to
Certificateholders. The Payahead Account will not be part of the Trust and the
Trustee will not have a security interest in the Payahead Account. Earnings on
Eligible Investments credited to the Payahead Account will be paid to the
Servicer. Full Prepayments during any Collection Period will be deposited
directly into the Collection Account for distribution to Certificateholders on
the Distribution Date next succeeding such Collection Period.
 
PAYMENTS ON CONTRACTS
 
     All collections on the Contracts will be deposited in or credited to the
Collection Account within two Business Days of the receipt by the Servicer of
payments from Obligors. Such collections will include: Full Prepayments and
partial prepayments (pending transfer of Payaheads on Rule of 78's Contracts to
the Payahead Account), Net Liquidation Proceeds and Net Insurance Proceeds, any
amounts deposited by Onyx
 
                                       33
<PAGE>   35
 
or the Seller in the Collection Account to purchase Contracts because of certain
material defects in documents related to the Contracts or certain breaches in
representations or warranties regarding the Contracts made by Onyx or the Seller
in the Agreement that materially and adversely affect the interests of the
Certificateholders or the Insurer, any amounts deposited by the Servicer in the
Collection Account to purchase Contracts as to which the Servicer has breached
certain servicing covenants; and any amounts deposited by the Servicer in the
Collection Account as a result of such entity exercising its right under certain
circumstances to purchase all or a portion of the Contracts. "Net Liquidation
Proceeds" are proceeds received by the Servicer (net of Liquidation Expenses)
upon liquidation of any Defaulted Contract. "Liquidation Expenses" are the
reasonable out-of-pocket expenses (exclusive of overhead expenses) incurred by
the Servicer in realizing upon a Defaulted Contract which are not recoverable
under any insurance policy. "Net Insurance Proceeds" are proceeds paid by any
insurer under a comprehensive and collision or vendor's single interest
insurance policy related to a Contract (other than funds used for the repair of
the related Financed Vehicle or otherwise released to the related Obligor in
accordance with normal servicing procedures) and proceeds from the Blanket
Insurance Policy, after reimbursement to the Servicer of expenses recoverable
under such policy. Partial prepayments of Rule of 78's Contracts are initially
deposited in the Collection Account and are transferred to the Payahead Account
on the Servicer Report Date.
 
DISTRIBUTIONS
 
     Subject to the last sentence of this paragraph, distributions on the
Certificates will be made on each Distribution Date by the Trustee out of net
collections on the Contracts (exclusive of amounts representing payment due in
the Collection Period in which such Distribution Date occurs and any future
Collection Periods) for the Collection Period preceding such Distribution Date
plus any Yield Supplement Amounts. The amount of such net collections and Yield
Supplement Amounts on each Distribution Date will be applied, first, to the
Servicer in payment of the Servicing Fee; second, payment of the Interest
Distribution and the Principal Distribution to the Certificateholders on such
Distribution Date in accordance with the Agreement (such Principal Distribution
to include the portion of the Pre-Funded Amount remaining in the Pre-Funding
Account at the end of the Funding Period), third, to the Insurer, the Surety
Bond Fee, and fourth, any balance shall be distributed to a separate spread
account trust to be applied in accordance with the spread account trust
agreement and the Insurance Agreement, which provide that to the extent funds
are not required to reimburse the Insurer for draws on the Surety Bond, to
satisfy obligations owing to the Insurer or to reserve against the possibility
of future draws, amounts remaining shall be released to the beneficiaries of the
spread account trust. Any amounts distributed pursuant to clause fourth above
will not be available to make distributions to the Certificateholders on the
current or any future Distribution Date. Under the Surety Bond, the Insurer is
obligated to provide for payment to the Trustee on each Distribution Date of the
amount, if any, by which the amount available for distribution from the net
collections on Contracts plus the Yield Supplement Amount is less than the sum
of the Servicing Fee, the Interest Distribution and the Principal Distribution
due to the Certificateholders for such Distribution Date. See "-- Distributions
of Principal and Interest."
 
INSURANCE ON FINANCED VEHICLES
 
     Each Obligor on a Contract is required to maintain insurance covering
physical damage to the Financed Vehicle of such Obligor in an amount not less
than the lesser of its maximum insurable value or the unpaid principal balance
under such Contract. Onyx is required to be named as a loss payee under the
policy of insurance obtained by the Obligor. The Financed Vehicle is required to
be insured against loss and damage due to fire, theft, transportation, collision
and other risks covered by comprehensive coverage. Onyx also maintains a
vendor's single interest insurance policy, as to which the Seller has been named
as an additional insured, which provides coverage upon repossession of a
Financed Vehicle in an amount equal to the lesser of the actual cash value of
such Financed Vehicle, the cost of repair or replacement for such Financed
Vehicle and the unpaid balance of the related Contract. Since Obligors may
choose their own insurers to provide the required coverage, the specific terms
and conditions of their policies vary.
 
     Onyx has obtained the Blanket Insurance Policy from United Financial
Casualty Company with a rating of "A" by A.M. Best, with respect to each
Contract. Subject to certain conditions, the Blanket Insurance
 
                                       34
<PAGE>   36
 
Policy covers the lesser of actual damage to a Financed Vehicle or the amount by
which the Obligor's unpaid remaining principal balance on the related Contract
exceeds the proceeds from disposition of the Financed Vehicle. Onyx's rights
under the Blanket Insurance Policy with respect to the Contracts under the
Blanket Insurance Policy have been assigned to the Trust pursuant to the
Agreement.
 
SERVICER REPORTS TO THE TRUSTEE AND THE INSURER
 
     The Servicer will perform certain monitoring and reporting functions for
the Trustee and the Insurer, including the preparation and delivery on the
Servicer Report Date to the Trustee and the Insurer of a statement setting forth
the amounts on deposit in the Collection Account, the sources of such amounts
and the amounts to be paid to Certificateholders (the "Distribution Date
Statement"). The Distribution Date Statement shall also include information
regarding Contracts purchased by the Servicer or repurchased by the Seller.
 
PURCHASE OF CONTRACTS
 
     The Servicer will have the option to purchase the remaining Contracts, and
thereby cause early retirement of the Certificates, as of any Distribution Date
on which the Aggregate Scheduled Balance of the Contracts is 10% or less of the
sum of the initial Pool Balance and the aggregate principal balance of all
Subsequent Contracts (as of each related Subsequent Transfer Date) conveyed to
the Trust. Any such purchase must be effected at a price equal to the Aggregate
Scheduled Balance of such Contracts plus accrued interest and all amounts due to
the Insurer under the Insurance Agreement. In addition, Onyx or the Seller is
required to purchase or repurchase, respectively, Contracts under certain
circumstances if certain representations and warranties made by Onyx or the
Seller respectively are incorrect in any manner that materially and adversely
affects the interest of the Certificateholders or the Insurer. Additionally, the
Servicer is required to purchase Contracts as to which the Servicer has breached
certain servicing covenants.
 
SERVICING FEE
 
     The Servicer will be entitled to compensation for the performance of its
obligations under the Agreement. The Servicer shall be entitled to receive an
amount equal to the product of one-twelfth of 1.00% per annum (the "Servicing
Fee Rate") and the Pool Balance as of the close of the preceding Collection
Period. As additional compensation, the Servicer or its designee shall be
entitled to retain all late payment charges, extension fees and similar items
paid in respect of the Contracts. The Servicer or its designee will also receive
as servicing compensation reinvestment earnings on Eligible Investments and the
amount, if any, by which the outstanding principal balance based on the Rule of
78's of a Contract that is subject to a Full Prepayment exceeds the Scheduled
Balance of such Contract. The Servicer shall pay all expenses incurred by it in
connection with its servicing activities under the Agreement and shall not be
entitled to reimbursement of such expenses except to the extent they constitute
Liquidation Expenses or expenses recoverable under an applicable insurance
policy.
 
REALIZATION UPON DEFAULTED CONTRACTS
 
     The Servicer will liquidate any Contract that comes into and continues in
default and as to which no satisfactory arrangements can be made for collection
of delinquent payments. Such liquidation may be through repossession or sale of
the Financed Vehicle securing such Contract or otherwise. In connection with
such repossession or other conversion, the Servicer will follow such procedures
as are normal and usual for holders of motor vehicle retail installment sales
contracts. In this regard, the Servicer may sell the Financed Vehicle at a
repossession or other sale.
 
                           DESCRIPTION OF THE INSURER
 
     The following information with respect to the Insurer has been furnished by
the Insurer and none of Onyx, the Seller or the Underwriter have made any
independent investigation of such information.
 
     The Insurer is a New York-domiciled monoline stock insurance company which
engages only in the business of financial guarantee and surety insurance. The
Insurer is licensed in 50 states in addition to the District of Columbia, the
Commonwealth of Puerto Rico and the territory of Guam. The Insurer insures
 
                                       35
<PAGE>   37
 
structured asset-backed, corporate, municipal and other financial obligations in
the U.S. and international capital markets. The Insurer also provides financial
guarantee reinsurance for structured asset-backed, corporate, municipal and
other financial obligations written by other major insurance companies.
 
     The Insurer's claims-paying ability is rated "Aaa" by Moody's, "AAA" by
Standard & Poor's, "AAA" by Duff & Phelps Credit Rating Co. and "AAA" by Nippon
Investors Service Inc. Such ratings reflect only the views of the respective
rating agencies, are not recommendations to buy, sell or hold securities and are
subject to revision or withdrawal at any time by such rating agencies.
 
     The Insurer is a wholly owned subsidiary of CapMAC Holdings Inc.
("Holdings"). NEITHER HOLDINGS NOR ANY OF ITS STOCKHOLDERS IS OBLIGATED TO PAY
ANY CLAIMS UNDER ANY SURETY BOND ISSUED BY THE INSURER OR ANY DEBTS OF THE
INSURER OR TO MAKE ADDITIONAL CAPITAL CONTRIBUTIONS TO THE INSURER.
 
     The Insurer is regulated by the Superintendent of Insurance of the State of
New York. In addition, the Insurer is subject to regulation by the insurance
laws and regulations of the other jurisdictions in which it is licensed. Such
insurance laws regulate, among other things, the amount of net exposure per risk
that the Insurer may retain, capital transfers, dividends, investment of assets,
changes in control, transactions with affiliates and consolidations and
acquisitions. The Insurer is subject to periodic regulatory examinations by the
same regulatory authorities.
 
     The Insurer's obligations under the Surety Bond may be reinsured. Such
reinsurance does not relieve the Insurer of any of its obligations under the
Surety Bond.
 
     THE SURETY BOND IS NOT COVERED BY THE PROPERTY/CASUALTY INSURANCE SECURITY
FUND SPECIFIED IN ARTICLE 76 OF THE NEW YORK INSURANCE LAW.
 
     As of December 31, 1995 and 1994, the Insurer had qualified statutory
capital (which consists of policyholders' surplus and contingency reserve) of
approximately $240 million and $170 million, respectively, and had not incurred
any debt obligations. Article 69 of the New York State Insurance Law requires
the Insurer to establish and maintain the contingency reserve, which is
available to cover claims under surety bonds issued by the Insurer.
 
     The audited financial statements of the Insurer prepared in accordance with
generally accepted accounting principles as of December 31, 1995 and 1994 and
for each of the years in the three-year period ended December 31, 1995 are
included in this Prospectus beginning at F-1. The unaudited financial statements
of the Insurer for the three and nine month periods ended September 30, 1996 and
1995 are made a part of this Prospectus beginning at F-19. Copies of the
Insurer's financial statements prepared in accordance with statutory accounting
standards, which differ from generally accepted accounting principles, and filed
with the Insurance Department of the State of New York and are available upon
request. The Insurer is located at 885 Third Avenue, New York, New York 10022,
and its telephone number is (212) 755-1155.

(i), (ii) and (viii) above and such other information in respect of the
Certificates as may be reasonably necessary for such Certificateholder's
preparation of federal income tax returns. See "Certain Tax Consequences."
    
 
EVIDENCE AS TO COMPLIANCE
 
     The Agreement will provide that a firm of independent public accountants
will furnish to the Trustee and the Insurer, on or before each March 15 after
the end of each fiscal year of the Servicer, beginning with the fiscal year
ended December 31, 1997, a statement as to compliance by the Servicer during the
preceding fiscal year with certain standards relating to the servicing of the
Contracts.
 
     The Agreement will also provide for delivery to the Trustee and the
Insurer, on each March 15 after the end of each fiscal year of the Servicer,
commencing with the fiscal year ended December 31, 1997, of a certificate signed
by an authorized officer of the Servicer stating that the Servicer has fulfilled
its obligations under the Agreement throughout the preceding fiscal year or, if
there has been a default in the fulfillment of any such obligation, describing
each such default.
 
     Copies of such statements and certificates may be obtained by
Certificateholders by a request in writing addressed to the Trustee.
 
CERTAIN MATTERS REGARDING THE SERVICER
 
     The Agreement will provide that the Servicer may not resign from its
obligations and duties as Servicer thereunder except upon determination that the
Servicer's performance of such duties is no longer permissible under applicable
law. No such resignation will become effective until the Trustee or a successor
servicer has assumed the Servicer's servicing obligations and duties under the
Agreement. See "-- The Trustee."
 
                                       37
<PAGE>   39
 
     The Agreement will further provide that neither the Servicer nor any of its
directors, officers, employees, and agents shall be under any liability to the
Trust or the Certificateholders for taking any action or for refraining from
taking any action pursuant to the Agreement, or for errors in judgment;
provided, however, that neither the Servicer nor any such person will be
protected against any liability that would otherwise be imposed by reason of
willful misfeasance, bad faith or negligence (except errors in judgment) in the
performance of duties or by reason of reckless disregard of obligations and
duties thereunder. In addition, the Agreement will provide that the Servicer is
under no obligation to appear in, prosecute or defend any legal action that is
not incidental to the Servicer's servicing responsibilities under the Agreement
and that, in its opinion, may cause it to incur any expense or liability. The
Servicer may, however, undertake any reasonable action that it may deem
necessary or desirable in respect of the Agreement and the rights and duties of
the parties thereto and the interests of the Certificateholders thereunder. In
such event, the legal expenses and costs of such action and any liability
resulting therefrom will be expenses, costs and liabilities of the Trust, and
the Servicer will be entitled to be reimbursed therefor out of the Collection
Account. Any such indemnification or reimbursement could reduce the amount
otherwise available for distribution to Certificateholders.
 
     Any corporation into which the Servicer may be merged or consolidated, or
any corporation resulting from any merger, conversion or consolidation to which
the Servicer is a party or any corporation succeeding to the business of the
Servicer, or, with respect to the Servicer's obligation as the Servicer, will be
the successor of the Servicer under the Agreement.
 
EVENTS OF DEFAULT
 
     "Events of Default" under the Agreement will consist of (i) any failure by
the Servicer to deposit in or credit to the Collection Account, the Payahead
Account or the Yield Supplement Reserve Account any amount required to be so
deposited or credited or to make the required distribution to
Certificateholders, which failure continues unremedied for three Business Days
after written notice from the Trustee or the Insurer is received by the Servicer
or discovery by the Servicer; (ii) any failure by the Servicer to deliver to the
Insurer or the Trustee certain reports required by the Agreement by the fifth
Business Day prior to the related Distribution Date or to perform certain other
covenants under the Agreement; (iii) any failure by the Servicer or the Seller
duly to observe or perform in any material respect any other covenants or
agreements of the Servicer or the Seller in the Agreement, which failure
materially and adversely affects the rights of Certificateholders, the Insurer
or the Trustee and which continues unremedied for 30 days after the giving of
written notice of such failure (A) to the Servicer or the Seller as the case may
be, by the Trustee or the Insurer or (B) to the Servicer or the Seller, as the
case may be, and to the Trustee by Holders of Certificates evidencing not less
than 25% of the Pool/Pre-Funding Balance or by the Insurer; (iv) certain events
of insolvency, readjustment of debt, marshalling of assets and liabilities, or
similar proceedings and certain actions by the Servicer or Seller indicating its
insolvency, reorganization pursuant to bankruptcy or similar proceedings or
inability to pay its obligations; (v) any breach of any of the representations
and warranties of the Servicer or the Seller (except for any breaches relating
to Contracts repurchased by the Seller or the Servicer) which breach has a
material adverse effect on the Trust and which continues for 30 days after the
giving of notice of such breach to the Seller or the Servicer, as the case may
be, by the Trustee or the Holders of Certificates evidencing not less than 25%
of the Pool/Pre-Funding Balance or the Insurer; (vi) any change in control of
the Servicer in violation of the covenant set forth in Section 7.2 of the
Agreement; and (vii) any determination by the Insurer that the quality of
performance of the Servicer is not in compliance with either the terms of the
Agreement or that the Servicer's performance is not adequate, as measured in
accordance with industry standards, in respect of all contracts serviced by the
Servicer.
 
RIGHTS UPON EVENT OF DEFAULT
 
     As long as an Event of Default under the Agreement remains unremedied, the
Trustee, the Insurer or Holders of Certificates evidencing not less than 25% of
the Pool/Pre-Funding Balance may terminate all the rights and obligations of the
Servicer under the Agreement, whereupon the Trustee will succeed to all the
responsibilities, duties and liabilities of the Servicer under the Agreement and
will be entitled to similar compensation arrangements; provided, however, that
the Trustee will not be obligated to purchase Contracts if
 
                                       38
<PAGE>   40
 
certain representations and warranties of Onyx as Servicer prove incorrect or if
certain covenants of Onyx as Servicer are breached. In the event that the
Trustee is unwilling or unable so to act, it may appoint, with the consent of
the Insurer, or petition a court of competent jurisdiction for the appointment
of, a successor with a net worth of at least $50,000,000 and whose regular
business includes the servicing of automotive retail installment sale contract
receivables.
 
     The Holders of Certificates evidencing not less than 51% of the
Pool/Pre-Funding Balance (not including any Certificates held by the Seller, the
Servicer or any affiliate) may, on behalf of all Certificateholders, with the
consent of the Insurer, waive any default by the Servicer or the Seller in the
performance of its obligations, other than failure to make any required deposits
to or payments from the Collection Account.
 
     The Trustee is under no obligation to exercise any of the trusts or powers
vested in it by the Agreement or to make any investigation of matters arising
thereunder or to institute, conduct, or defend any litigation thereunder or in
relation thereto at the request, order, or direction on any of the
Certificateholders, unless such Certificateholders have offered to the Trustee
reasonable security or indemnity against the costs, expenses and liabilities
which may be incurred therein or thereby. No Certificateholder will have any
right under the Agreement to institute any proceeding with respect to the
Agreement, unless such Holder previously has given to the Trustee written notice
of default and unless the Holders of Certificates evidencing not less than 25%
of the Pool/Pre-Funding Balance with the consent of the Insurer have made
written request upon the Trustee to institute such proceeding in its own name as
Trustee thereunder and have offered to the Trustee reasonable indemnity and the
Trustee for 30 days has neglected or refused to institute any such proceedings.
 
     Notwithstanding any provision in the Agreement to the contrary, in the
event that the Insurer is in default under the Surety Bond or is subject to any
insolvency proceeding, the Insurer shall not have the right to terminate the
Servicer, or to control or direct the actions of the Seller, the Servicer or the
Trustee pursuant to the terms of the Agreement, nor shall the consent of the
Insurer be required with respect to any action (or waiver of a right to take
action) to be taken by the Seller, the Servicer or the Trustee; provided, that
the consent of the Insurer shall be required at all times with respect to any
amendment of the Agreement.
 
AMENDMENT
 
   
     The Agreement may be amended by the Seller, the Servicer and the Trustee,
without the consent of the Certificateholders but with the consent of the
Insurer, to cure any ambiguity, correct or supplement any provision therein
which may be inconsistent with any other provision therein, or make any other
provisions with respect to matters or questions arising under such Agreement
which are not inconsistent with the provisions of the Agreement; provided that
such action will not, in the opinion of counsel satisfactory to the Trustee,
materially and adversely affect the interest of any Certificateholder. The
Agreement may also be amended by the Seller, the Servicer and the Trustee with
the consent of the Holders of Certificates evidencing not less than 51% of the
Pool/Pre-Funding Balance and the Insurer for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
the Agreement or of modifying in any manner the rights of Certificateholders;
provided, however, that no such amendment may (i) increase or reduce in any
manner the amount of, or accelerate or delay the timing of, collection of
payments on Contracts or distributions required to be made on any Certificate or
(ii) reduce the aforesaid percentage required to consent to any such amendment,
without the consent of all Certificateholders.
    
 
LIST OF CERTIFICATEHOLDERS
 
     Upon written request of the Servicer, the Trustee will provide to the
Servicer within 15 days after receipt of such request a list of the names and
addresses of all Certificateholders of record as of the most recent Record Date.
Upon written request by three or more Certificateholders or by Holders of
Certificates evidencing not less than 25% of the Pool/Pre-Funding Balance, the
Trustee will afford such Certificateholders access during business hours to the
current list of Certificateholders for purposes of communicating with other
Certificateholders with respect to their rights under the Agreement.
 
     The Agreement will not provide for the holding of any annual or other
meetings of Certificateholders.
 
                                       39
<PAGE>   41
 
TERMINATION
 
     The obligations of the Seller, the Servicer and the Trustee to the
Certificateholders pursuant to the Agreement will terminate upon the earlier of
(i) the maturity or other liquidation of the last Contract and the disposition
of any amounts received upon liquidation of any remaining Contracts that are
part of the Trust Property and (ii) (a) the payment to Certificateholders of all
amounts required to be paid to them pursuant to the Agreement and the
disposition of all property held as part of the Trust, (b) termination of the
Surety Bond in accordance with its terms and surrender of the Surety Bond to the
Insurer for cancellation, (c) the payment of all amounts owed to the Trustee
under the Agreement and (d) the payment of all amounts owed to the Insurer under
the Insurance Agreement and the spread account trust agreement. In order to
avoid excessive administrative expense, the Servicer is permitted at its option
to purchase the remaining Contracts from the Trust as of the Distribution Date
as of which the then outstanding Aggregate Scheduled Balance of the Contracts is
10% or less of the sum of the initial Pool Balance and the aggregate principal
balance of all Subsequent Contracts (as of each respective Subsequent Transfer
Date) conveyed to the Trust at a price equal to the Aggregate Scheduled Balance
of such Contracts plus accrued interest on the Contracts and all amounts due to
the Insurer under the Insurance Agreement. The Trustee will give written notice
of termination to each Certificateholder of record. The final distribution to
any Certificateholder will be made only upon surrender and cancellation of such
Certificateholder's Certificate at an office or agency of the Trustee specified
in the notice of termination. Any funds remaining in the Trust, after the
Trustee has taken certain measures to locate a Certificateholder and such
measures have failed, will be distributed to a charity designated by the
Servicer.
 
THE TRUSTEE
 
     The Trustee makes no representations as to the validity or sufficiency of
the Agreement, the Certificates, or any Contracts or related documents, or the
investment of any monies by the Servicer before such monies are deposited in or
credited to the Collection Account. The Trustee has not examined the Contracts.
If no Event of Default has occurred, the Trustee is required to perform only
those duties specifically required of it under the Agreement. Generally, those
duties are limited to the receipt of the various certificates, reports or other
instruments required to be furnished to the Trustee under the Agreement, the
making of distributions to Certificateholders in the amounts specified in
certificates provided by the Servicer and drawing on the Surety Bond if required
to make distributions to the Certificateholders.
 
     Bankers Trust Company is the Trustee under the Agreement. The Trustee, and
any of its affiliates, may hold Certificates in their own names. In addition,
for the purpose of meeting the legal requirements of certain local
jurisdictions, the Servicer and the Trustee acting jointly shall have the power
to appoint co-trustees or separate trustees of all or any part of the Trust. In
the event of such appointment, all rights, powers, duties and obligations
conferred or imposed upon the Trustee by the Agreement shall be conferred or
imposed upon the Trustee and such separate trustee or co-trustee jointly, or, in
any jurisdiction in which the Trustee shall be incompetent or unqualified to
perform certain acts, singly upon such separate trustee or co-trustee who shall
exercise and perform such rights, powers, duties and obligations solely at the
direction of the Trustee.
 
     The Trustee may resign at any time, in which event a successor trustee will
be appointed pursuant to the terms of the Agreement. The Trustee may be removed
if it ceases to be eligible to continue as such under the Agreement or if the
Trustee becomes insolvent. Any resignation or removal of the Trustee and
appointment of a successor does not become effective until acceptance of the
appointment by the successor trustee.
 
   
     The Trustee shall be entitled to a fee payable on an annual basis by Onyx.
The Agreement will further provide that the Trustee will be entitled to
indemnification by the Servicer for, and will be held harmless against, any
loss, liability, or expense incurred by the Trustee not resulting from the
Trustee's own willful misfeasance, bad faith, or negligence (other than errors
in judgment) or by reason of breach of any of their respective representations
or warranties set forth in the Agreement, except to the extent that such loss,
liability, or expense relates to a specific Contract or Contracts or certain
taxes that could be asserted against the Trustee, the Trust or the Contracts, in
which case the Trustee would be entitled to be indemnified by the Trust.

     Onyx and the Insurer may maintain other banking relationships with the
Trustee in the ordinary course of business.
 
                     CERTAIN LEGAL ASPECTS OF THE CONTRACTS
 
GENERAL
 
     The Contracts are "chattel paper" as defined in the Uniform Commercial Code
as in effect in California ("UCC"). Pursuant to the UCC, an ownership interest
in chattel paper may be perfected by possession of the collateral or filing a
UCC-1 financing statement with the California Secretary of State.
 
     Under the Agreement, the Trustee initially will have custody of the
Contracts following the sale of the Contracts to the Trust and will hold the
Contracts as bailee for the benefit of the Trust. Upon receiving the prior
consent of the Insurer, which cannot be unreasonably withheld, the Servicer may
be appointed by the Trustee to act as the custodian of the Contracts. Upon such
appointment physical possession of the Contracts would shift from the Trustee to
the Servicer. While the Contracts will not be physically marked to indicate the
ownership interest thereof by the Trust, UCC-1 financing statements will be
filed with the California Secretary of State to perfect by filing and give
notice of the Trust's ownership interest in the Contracts. If, through
inadvertence or otherwise, any of the Contracts were sold to another party who
purchased such Contracts in the ordinary course of its business and took
possession of such Contracts, the purchaser would acquire an interest in the
Contracts superior to the interests of the Trust if the purchaser acquired the
Contracts in good faith, for value and without actual knowledge of the Trust's
ownership interest in the Contracts.
 
SECURITY INTERESTS IN THE FINANCED VEHICLES
 
   
     All Financed Vehicles were either registered in the State of California,
Arizona, Washington or one of the other states listed above under "THE
CONTRACTS" at the time of origination of the related Contract. Perfection of
security interests in motor vehicles is generally governed by state certificate
of title statutes or by the motor vehicle registration laws of the state in
which each vehicle is located. Security interests in vehicles registered in the
State of California (the state in which approximately 81.0% of the Financed
Vehicles are located) may be perfected by depositing with the California
Department of Motor Vehicles a properly endorsed certificate of title showing
the secured party as legal owner or an application for an original registration
together with an application for registration of the secured party as legal
owner. Security interests in vehicles registered in the State of Arizona (the
state in which approximately 9.9% of the Financed Vehicles are located) are
perfected by delivering to the assessor of the county in which the Obligor
resides a properly completed application for a certificate of title signed by
the Obligor upon a form supplied by the Motor Vehicle Division of the Arizona
Department of Transportation, noting the name of the lienholder, the amount and
date of the lien and the lienholder's mailing address. Security interests in
vehicles registered in the State of Washington (the state in which approximately
6.56% of the Financed Vehicles are located) are perfected upon the Washington
Department of Licensing's receipt of the existing certificate of ownership, if
any, and an application for a certificate of ownership containing the name and
address of the secured party, and tender of the required fee. Security interests
in vehicles registered in Hawaii, Nevada and Oregon, the other states in which
Contracts were originated, are perfected, generally, in the same manner. The
Seller has warranted to the Trust in the Agreement that Onyx has taken all steps
necessary to obtain a perfected first priority security interest with respect to
all Financed Vehicles securing the Contracts and that such security interest has
been assigned to the Trust. If Onyx fails, because of clerical errors or
otherwise, to effect or maintain the notation of its security interest on the
certificate of title relating to a Financed Vehicle, the Trust may not have a
first priority security interest in such Financed Vehicle.
    
 
     The Seller will sell the Contracts and assign the security interest in each
Financed Vehicle to the Trust. However, because of the administrative burden and
expense, the Trust will not amend the certificates of title to identify the
Trust as the new secured party. Accordingly, Onyx, will continue to be named as
the secured party on the certificates of title relating to the Financed
Vehicles. Under the law of California, Arizona,
 
                                       41
<PAGE>   43
 
Washington and most other states including Hawaii, Nevada and Oregon, the
assignment of the Contracts is an effective conveyance of the security interests
in the Financed Vehicles without amendment of the lien noted on the related
certificate of title and the new secured party succeeds to the assignor's rights
as the secured party. However, there exists a risk in not identifying the Trust
as the new secured party on the certificate of title that, through fraud or
negligence, the security interest of the Trust could be released.
 
     In the absence of fraud or forgery by the Financed Vehicle owner or
administrative error by state recording officials, notation of the lien of Onyx
will be sufficient to protect the Trust against the rights of subsequent
purchasers of a Financed Vehicle or subsequent lenders who take a security
interest in a Financed Vehicle. If there are any Financed Vehicles as to which
Onyx has failed to perfect the security interest assigned to the Trust, such
security interest would be subordinate to, among others, subsequent purchasers
of the Financed Vehicles and holders of perfected security interests.
 
     In the event that the owner of a Financed Vehicle relocates to a state
other than the state in which the Financed Vehicle was registered at the
inception of the Contract, under the laws of most states the perfected security
interest in the Financed Vehicle would continue for four months after such
relocation and thereafter, in most instances, until the owner re-registers the
Financed Vehicle in such state. A majority of states generally require surrender
of a certificate of title to re-register a vehicle. Therefore, the Servicer will
provide the department or motor vehicles or other appropriate state or county
agency of the state of relocation with the certificate of title so that the
owner can effect the re-registration. If the Financed Vehicle owner moves to a
state that provides for notation of lien on the certificate of title to perfect
the security interests in the Financed Vehicle, Onyx, absent clerical errors or
fraud, would receive notice of surrender of the certificate of title if Onyx's
lien is noted thereon. Accordingly, Onyx will have notice and the opportunity to
re-perfect the security interest in the Financed Vehicle in the state of
relocation. If the Financed Vehicle owner moves to a state which does not
require surrender of a certificate of title for registration of a motor vehicle,
reregistration could defeat perfection. In the ordinary course of servicing its
portfolio of motor vehicle installment sales contracts, Onyx takes steps to
effect such re-perfection upon receipt of notice of registration or information
from the Obligor as to relocation. Similarly, when an Obligor under a Contract
sells a Financed Vehicle, the Servicer must provide the owner with the
certificate of title, or the Servicer will receive notice as a result of its
lien noted thereon and accordingly will have an opportunity to require
satisfaction of the related Contract before release of the lien. Under the
Agreement, Onyx, at its cost, is obligated to maintain the continuous perfection
of its security interest in the Financed Vehicle.
 
     Under the law of California and most other states, liens for unpaid taxes,
storage of and repairs performed on a motor vehicle take priority even over a
perfected security interest. Under the laws of Arizona and Washington, however,
certain liens for storage of and repairs performed on a motor vehicle do not
take priority over a perfected security interest. The Internal Revenue Code of
1986, as amended, also grants priority to certain federal tax liens over the
lien of a secured party. The Seller will represent in the Agreement that as of
the initial issuance of the Certificates no such state or federal liens exist
with respect to any Financed Vehicle securing payment on any Contract. However,
such liens could arise at any time during the term of a Contract. No notice will
be given to the Servicer in the event such a lien arises.
 
ENFORCEMENT OF SECURITY INTERESTS IN FINANCED VEHICLES
 
     The Servicer, on behalf of the Trust, may take action itself to enforce its
security interest with respect to Defaulted Contracts by repossession and resale
of the Financed Vehicles securing such Defaulted Contracts. In addition to the
provisions of the UCC, under California law the Contracts originated in
California are subject to the provisions of the Rees-Levering Motor Vehicle
Sales and Finance Act (the "Rees-Levering Act"). In California the provisions of
the Rees-Levering Act control in the event of a conflict with the provisions of
the UCC. Contracts originated in Arizona are subject to the Motor Vehicle Time
Sales Disclosure Act of Arizona. Contracts originated in Washington are subject
to the Credit Disclosure Act of Washington. Contracts originated in states other
than California, Arizona and Washington may be subject to retail installment
sales laws and similar laws of those states. Under the UCC and laws applicable
in most states, a creditor can, without prior notice to the debtor, repossess a
motor vehicle securing a motor vehicle installment contract by voluntary
surrender, by "self-help" repossession without breach of peace, and by
 
                                       42
<PAGE>   44
 
   
judicial process. The Rees-Levering Act in California and similar laws in
Arizona, Washington and other states place restrictions on repossession sales,
including notice to the debtor of the intent to sell and of the debtor's right
to redeem the vehicle. In addition, the UCC requires commercial reasonableness
in the conduct of the sale.
    
 
     In the event of such repossession and resale of a Financed Vehicle, the
Servicer for the benefit of the Trust would be entitled to be paid out of the
sale proceeds before such proceeds could be applied to the payment of the claims
of unsecured creditors or the holders of subsequently perfected security
interests or, thereafter, to the debtor.
 
     Under the UCC and laws applicable in most states, a creditor is entitled to
obtain a deficiency judgment from a debtor for any deficiency on repossession
and resale of the motor vehicle securing such debtor's motor vehicle installment
contract. However, some states impose prohibitions or limitations on deficiency
judgments, including the State of Washington. Under California and Arizona law
the proceeds from the resale of the motor vehicle securing the debtor's motor
vehicle installment contract are applied first to the expenses of resale and
repossession, and if the remaining proceeds are not sufficient to repay the
indebtedness, the creditor may seek a deficiency judgment for the balance. The
priority of application of proceeds from the sale of repossessed vehicles under
the Contracts originated in most other states, including Hawaii, Nevada and
Oregon, is similar.
 
     Certain other statutory provisions, including federal and state bankruptcy
and insolvency laws, may limit or delay the ability of the creditor to repossess
and resell collateral or enforce a deficiency judgment.
 
     In the event that deficiency judgments are not satisfied, are satisfied at
a discount or are discharged in whole or in part, in bankruptcy proceedings,
including proceeds under Chapter 13 of Bankruptcy Reform Act of 1978, as
amended, the loss will be borne by the Trust.
 
OTHER MATTERS
 
     The so-called "holder-in-due-course" rule of the Federal Trade Commission
is intended to defeat the ability of the transferor of a consumer credit
contract which is the seller of goods which gave rise to the transaction (and
certain related lenders and assignees) to transfer such contract free of notice
of claims by the debtor thereunder. The effect of this rule is to subject the
assignee of such a contract to all claims and defenses which the debtor could
assert against the seller of goods. Liability under this rule is limited to
amounts paid under a Contract; however, the Obligor may also assert the rule to
set off remaining amounts due as a defense against a claim brought by the
Trustee against such Obligor.
 
     The courts have imposed general equitable principles on repossession and
litigation involving deficiency balances. These equitable principles may have an
effect of relieving an Obligor from some or all of the legal consequences of a
default.
 
     Numerous other federal and state consumer protection laws impose
requirements applicable to the origination and servicing of the Contracts,
including the Truth-in-Lending Act, the Federal Trade Commission Act, the Fair
Credit Billing Act, the Fair Credit Reporting Act, the Equal Credit Opportunity
Act, the Fair Debt Collection Practices Act, and the Rees-Levering Act. The
Seller has represented to the Trust in the Agreement that each of the Contracts,
and the sale of the related Financed Vehicles sold thereunder, complied with all
material requirements of such laws and the regulations issued pursuant thereto.
 
REPURCHASE OBLIGATION
 
     Under the Agreement, the Seller will make representations and warranties
relating to validity, subsistence, perfection and priority of the security
interest in each Initial Financed Vehicle as of the Closing Date and the
security interest in each Subsequent Financed Vehicle as of each related
Subsequent Transfer Date. See "The Certificates and the Agreement -- Sale and
Assignment of the Contracts." Accordingly, if any defect exists in the
perfection of the security interest in any Financed Vehicle as of the Closing
Date or any Subsequent Transfer Date, as applicable, and such defect adversely
affects the Trust's interest in the related Contract, such defect would
constitute a breach of a warranty under the Agreement and would create an
 
                                       43
<PAGE>   45
 
obligation of the Seller to repurchase such Contract unless the breach is cured.
Additionally, in the Agreement the Servicer will make certain representations,
warranties and affirmative covenants regarding, among other things, the
maintenance of the security interest in each Financed Vehicle, the breach of
which would create an obligation of the Servicer to purchase any affected
Contract from the Trust unless the breach is cured.
 
                            CERTAIN TAX CONSEQUENCES
 
   
     The following is a summary of the material anticipated Federal income tax
consequences of the purchase, ownership, and disposition of Certificates. This
summary is based upon laws, regulations, rulings, and decisions currently in
effect, all of which are subject to change (which change may be retroactive).
The discussion does not deal with all Federal tax consequences applicable to all
categories of investors, some of which may be subject to special rules. In
addition, this summary is generally limited to investors who will hold the
Certificates as "capital assets" (generally, property held for investment)
within the meaning of Section 1221 of the Internal Revenue Code of 1986, as
amended (the "Code"). Consequences to individual investors of investment in the
Certificates will vary according to their individual circumstances. In addition,
this summary generally does not address foreign, state or local taxation issues.
Accordingly, investors should consult their own tax advisors to determine the
Federal, state, local, and other tax consequences of the purchase, ownership,
and disposition of the Certificates. Prospective investors should note that no
rulings have been or will be sought from the Internal Revenue Service (the
"IRS") with respect to any of the Federal income tax consequences discussed
below, and no assurance can be given that the IRS will not take contrary
positions.
    
 
   
     BECAUSE MANY OF THE ISSUES DISCUSSED HEREIN ARE COMPLEX AND THEIR
RESOLUTION IS UNCERTAIN, INVESTORS ARE URGED TO CONSULT THEIR TAX ADVISORS TO
DETERMINE THE FEDERAL, STATE, LOCAL, AND FOREIGN TAX CONSEQUENCES OF THE
PURCHASE, OWNERSHIP, AND DISPOSITION OF THE CERTIFICATES.
    
 
TAX STATUS OF THE TRUST
 
     In the opinion of Brobeck, Phleger and Harrison, special tax counsel to the
Seller, the Trust will be classified as a grantor trust and not as a partnership
or as an association taxable as a corporation for Federal income tax purposes.
Accordingly, subject to the discussion below, each Certificate Owner will be
subject to Federal income taxation as if it owned directly its interest in each
asset owned by the Trust and paid directly its share of reasonable expenses paid
by the Trust.
 
TREATMENT OF CERTIFICATE OWNERS' INTEREST IN TRUST ASSETS
 
     Each Certificate Owner could be considered to own either (i) an undivided
interest in a single debt obligation held by the Trust and having a principal
amount equal to the total stated principal amount of the Contracts and an
interest rate equal to the Pass-Through Rate, or (ii) an interest in each of the
Contracts, in the Pre-Funding Account, in the Yield Supplement Agreement and any
other Trust Property. The Agreement will express the intent of the Seller to
sell, and the Certificateholders to purchase, the Contracts (other than the
Retained Strip (as defined below)) and the Seller, the Certificateholders, and
each Certificate Owner, by accepting a beneficial interest in a Certificate,
will agree to treat the Certificates as ownership interests in the Contracts,
the Pre-Funding Account, the Yield Supplement Agreement and any other Trust
Property.
 
     Treatment as Debt Obligation.  If a Certificate Owner were considered to
own an undivided interest in a single debt obligation, rather than reporting its
share of the interest accrued on each Contract it would, in general, be required
to include in income interest accrued or received on the principal amount of the
Certificates at the Pass-Through Rate in accordance with its usual method of
accounting.
 
     The Certificates would be subject to the original issue discount ("OID")
rules, generally in the manner discussed below with respect to Stripped
Contracts. However, in determining whether such OID is de minimis, the weighted
average life of the Certificates would be determined using a reasonable
assumption regarding anticipated prepayments (a "Prepayment Assumption").
Original issue discount includible in income for any accrual period (generally,
the period between payment dates) would generally be calculated using a
Prepayment Assumption and an anticipated yield established as of the date of
initial sale of the
 
                                       44
<PAGE>   46
 
Certificates, and would increase or decrease to reflect prepayments at a faster
or slower rate than anticipated. The Certificates would also be subject to the
market discount provisions of the Code to the extent that a Certificate Owner
purchased such Certificates at a discount from the initial issue price (as
adjusted to reflect prior accruals of original issue discount).
 
     The remainder of the discussion herein assumes that a Certificate Owner
will be treated as owning an interest in each Contract (and the proceeds
thereof), in the Pre-Funding Account, and an interest in the Yield Supplement
Agreement and any other Trust Property, although the Servicer will report
information on an aggregate basis.
 
SPECIFIC TAX ISSUES CONCERNING RULE OF 78'S CONTRACTS
 
   
     For the Rule of 78's Contracts, the purchase price paid by the
Certificateholders for each Contract will reflect the principal balance of such
Contract as of the Cut-Off Date (with respect to Initial Contracts) or as of the
applicable Subsequent Transfer Date (with respect to Subsequent Contracts) based
on the Rule of 78's (the "Cut-Off Date Scheduled Balance"). Because the Rule of
78's allocates a greater portion of the early payments under a Contract to
interest than the actuarial method, the Cut-Off Date Scheduled Balance of each
Contract exceeds the amount that would have been its principal balance as of the
Cut-Off Date or Subsequent Transfer Date if each Contract had been amortized
from origination under an actuarial method (such amount, the "Cut-Off Date
Actuarial Balance").
    
 
     The Trustee and the Servicer intend to account for interest and principal
on the Rule of 78's Contracts using the actuarial method, but based on the
Cut-Off Date Scheduled Balance rather than the Cut-Off Date Actuarial Balance.
As described above, the remaining payments due on a Rule of 78's Contract are
not sufficient to amortize the Cut-Off Date Scheduled Balance of such Contract
at a yield equal to its APR. Accordingly, in order to amortize the Cut-Off Date
Scheduled Balance over the remaining term of the Rule of 78's Contract using the
actuarial method of accounting, the Servicer will recompute the effective yield
of such Contract based on the remaining payments due and the Cut-Off Date
Scheduled Balance (such yield, stated as a per annum rate, the "Recomputed
Yield") and will allocate each payment of Monthly P&I between principal and
interest on each Contract beginning with the Cut-Off Date Scheduled Balance by
applying the Recomputed Yield instead of the APR.
 
     The proper tax method for accounting for the Rule of 78's Contracts is
uncertain. As described above, the Servicer and the Trustee intend to report
income to the Certificateholders based on the Recomputed Actuarial Method (as
defined below) and assuming for purposes of calculating OID, that the income on
the Scheduled Balance of each Contract, at a rate equal to the Recomputed Yield
minus the Retained Strip, would be treated as "qualified stated interest." See
"-- Discount and Premium -- Original Issue Discount on Stripped Contracts."
However, prospective investors should consult their tax advisors as to whether
they may be required or permitted to use the Rule of 78's method to account for
interest on the Rule of 78's Contracts. A Certificateholder will be furnished
information for federal income tax purposes enabling him to report interest on
such Contracts under the Rule of 78's method of accounting only upon written
request to the Trustee, and payment of the actual costs of producing the same.
Alternatively, the IRS could take the position that a Certificate Owner that
amortizes a Rule of 78's Contract under the Recomputed Actuarial Method (rather
than under the Rule of 78's method) has actually acquired a Contract having an
actual principal balance equal to the Cut-Off Date Actuarial Balance at a
premium equal to the difference between the Cut-Off Date Actuarial Balance and
the Cut-Off Date Scheduled Balance, and that the actuarial method must be
applied from the time of a Contract's origination using its actual APR. In that
event (unless the Certificate Owner were to make a Total Accrual Election, as
described below) it appears likely that the Certificate Owner would be required
to include income at a rate equal to the full APR of the Contract (minus the
Retained Strip) on a balance equal to the Cut-Off Date Actuarial Balance
amortized based on the APR and an actuarial method, and should be entitled to
amortize the difference between the Cut-Off Date Scheduled Balance and the Cut-
Off Date Actuarial Balance to the extent it had a valid election in effect. See
"-- Discount and Premium."
 
     As an alternative to separately accruing stated interest, OID, de minimis
OID, market discount, de minimis market discount, unstated interest, premium,
and acquisition premium, a Certificate Owner may
 
                                       45
<PAGE>   47
 
elect to include all income that accrues on the Certificate using the constant
yield method. If a Certificate Owner makes this election (the "Total Accrual
Election"), income on a Certificate will be calculated as though (i) the issue
price of the Certificate were equal to the Certificate Owner's adjusted basis in
the Certificate immediately after its acquisition by the Certificate Owner; (ii)
the Certificate were issued on the Certificate Owner's acquisition date; and
(iii) none of the interest payments on the Certificate are "qualified stated
interest" payments. A Certificate Owner may make such an election for a
Certificate that has premium or market discount, respectively, only if the
Certificate Owner makes, or has previously made, an election to amortize bond
premium or to include market discount in income currently.
 
     If a Rule of 78's Contract is prepaid in full, any amount collected from
the Obligor pursuant to the Contract in excess of the principal balance thereof
and accrued interest thereon, computed using the actuarial method and the
Recomputed Yield, as described above (such method, the "Recomputed Actuarial
Method" and such amount, the "Recomputed Principal Balance"), will be paid to
the owner of retained yield. Such amount may be treated as additional income in
the nature of a prepayment penalty to a Certificate Owner who had reported
income with respect to the Contracts on the Recomputed Actuarial Method, and
would be deductible only to the extent described below. Alternatively, such
amount might be treated as an interest in the Contract retained by the owner of
retained yield, in which event it would not be included in a Certificate Owner's
income.
 
INCOME ON ALL CONTRACTS
 
     For federal income tax purposes, the owner of retained yield will be
treated as having retained a portion (the "Retained Strip") of the interest due
on each Contract having a yield in excess of   % calculated using the actuarial
method (each, a "Stripped Contract") equal to the difference between (x) the
Recomputed Yield of the Contract and (y)   %. The Retained Strip will be treated
as "stripped coupons" within the meaning of Section 1286 of the Code, and the
Stripped Contracts will be treated as "stripped bonds." If, as described above,
the IRS were to take the position that the actuarial method must be applied
consistently from the time of origination of a Contract, the Retained Strip
would consist of a different portion of the interest that accrues at the APR on
the actuarial principal balance of a Contract for each. ("Contract Due Period").
 
   
     Each Certificate Owner will be required to report on its federal income tax
return its share of the gross income of the Trust, including interest and
certain other charges accrued on the Contracts, original issue discount and
market discount (to the extent described below), payments received under the
Yield Supplement Agreement (to the extent treated as income), investment
earnings on amounts held pending distribution, and any gain upon collection or
disposition of the Contracts. Such income (other than any original issue
discount or market discount, as described below) would be includible in income
in accordance with a Certificate Owner's usual method of accounting.
Accordingly, interest will be includible in a Certificate Owner's gross income
at the time it accrues on the Contracts, or, in the case of Certificate Owners
who are cash basis taxpayers, when received by the Servicer on behalf of
Certificate Owners. Because (i) interest accrues on the Contracts over differing
monthly periods and is paid in arrears and (ii) interest collected on a Contract
is generally paid to Certificate Owners in the following month, the amount of
interest accruing to a Certificate Owner during any month will not equal the
interest distributed in that month.
    
 
     A Certificate Owner will be entitled to deduct, consistent with its method
of accounting, its pro rata share of reasonable servicing fees and other fees
paid or incurred by the Trust as provided in Section 162 or 212 of the Code. If
a Certificate Owner is an individual, estate or trust, the deduction for such
holder's share of such fees will be allowed only to the extent that all of such
holder's miscellaneous itemized deductions, including such holder's share of
such fees, exceed 2% of such holder's adjusted gross income. In addition, in the
case of Certificate Owners who are individuals, certain otherwise allowable
itemized deductions will be reduced, but not by more than 80%, by an amount
equal to 3% of such holder's adjusted gross income in excess of a statutorily
defined threshold ($117,950 in the case of a married couple filing jointly for
the taxable year beginning in 1996 and will be adjusted for inflation each year
thereafter). The Servicer will not report to Certificate Owners the amount of
income or deductions attributable to interest earned on collections and certain
other amounts (which are includible in gross income, but the deductions of which
are subject to the
 
                                       46
<PAGE>   48
 
foregoing limitations) and, accordingly, such a holder will not have sufficient
information from the report itself to accurately reflect the holder's net
taxable income.
 
   
     For administrative convenience, the Servicer intends to report the total
amount of income with respect to the Certificates on an aggregate basis (as
though all of the Contracts, the Pre-Funding Account and the Yield Supplement
Agreement were a single obligation), rather than on an asset-by-asset basis. The
amount and, in some instances, character, of the income reported to a
Certificate Owner may differ under this method for a particular period from that
which would be reported if income were reported on a precise asset-by-asset
basis. Accordingly, the IRS could require that a Certificate Owner calculate its
income either (i) on an asset-by-asset basis, accounting separately for each
Contract, for earnings on amounts on deposit in the Pre-Funding Account, and for
payments made under the Yield Supplement Agreement, or (ii) aggregating all
Stripped Contracts under the aggregation rule described below and accounting for
the remaining Contracts, the Pre-Funding Account and the Yield Supplement
Agreement on an asset-by-asset basis. If reporting on an aggregate basis results
in under-reporting of income, or if the IRS were to take a position different
from that adopted by the Trust with respect to any issue, a Certificate Owner
could be required to pay interest on underpayments of tax and could be subject
to penalties for under-reporting of income. See "-- Discount and
Premium -- Original Issue Discount on Stripped Contracts." In computing its
income on an asset-by-asset basis, a Certificate Owner would allocate its tax
basis among the Contracts and its interest in the Pre-Funding Account and in the
Yield Supplement Agreement in proportion to their fair market values. Because
the Recomputed Yields of the Contracts vary widely, the allocation of basis and
computation of income on an asset-by-asset basis could have a more significant
effect on the income of a Certificate Owner than it would if the Contracts had
more uniform characteristics.
    
 
   
     The remainder of the disclosure generally describes the Code provisions
governing reporting of income on the Contracts, the Pre-Funding Account and the
Yield Supplement Agreement on a separate asset basis.
    
 
DISCOUNT AND PREMIUM
 
     In determining whether a Certificate Owner has purchased its interest in
the Contracts (or any Contract) at a discount and whether such Contracts (or any
Contract) have OID, a portion of the purchase price of a Certificate should be
allocated to the Certificate Owner's undivided interest in accrued but unpaid
interest, amounts collected at the time of purchase but not distributed and
rights to receive Yield Supplement Amounts. As a result, the portion of the
purchase price allocable to a Certificate Owner's undivided interest in the
Contracts (or any Contract) (the "Purchase Price") will be decreased and the
potential OID on the Contracts (or any Contract) could be increased.
 
   
     Original Issue Discount on Stripped Contracts. Because the Stripped
Contracts represent stripped bonds, they will be subject to the OID rules of the
Code. Under Treasury Regulations issued under Section 1286 of the Code (the
"Section 1286 Regulations"), it appears that, in general, the portion of the
interest on each Contract payable to the Certificate Owners may be treated as
"qualified stated interest." As a result, the amount of OID on a Contract (or
Contracts) will equal the amount, if any, by which the Purchase Price is less
than the portion of the remaining principal balance of the Contract (or
Contracts) allocable to the interest acquired. However, if the IRS were to take
the position that the actuarial method must be applied consistently from the
time of origination of a Contract at a rate equal to the Contract's APR (such
method, the "Origination Actuarial Method"), then a Certificate Owner would be
deemed to receive interest at a different rate for each Collection Period and
the remainder of the interest deemed to accrue at the Contract's APR on the
actuarial principal balance would be included in the Retained Strip. As a
result, it appears that none of the interest on the Stripped Contracts would be
"qualified stated interest." In that event, the entire yield deemed to accrue to
a Certificate Owner would be includible in income as OID, based on a yield which
should generally equal a rate equal to      %.
    
 
     The Trustee will calculate OID, if any, on all of the Contracts (including
Stripped Contracts) on an aggregate basis and without the use of a prepayment
assumption. Regulations issued under the OID provisions of the Code (the "OID
Regulations") suggest that all payments on the Stripped Contracts that are
Initial Contracts allocable to the Certificates may be aggregated in determining
whether the Stripped Contracts will
 
                                       47
<PAGE>   49
 
be treated as having OID, although the regulation does not include the
Subsequent Contracts, which cannot technically be aggregated with the Initial
Contracts because the Stripped Contracts are issued on a subsequent date.
Separate accounting for the Stripped Contracts and the Contracts that are not
stripped would reduce the possibility that the Stripped Contracts would be
treated as issued with OID; however, as discussed below, (any Contracts having a
yield equal to      % (using a Recomputed Yield for Rule of 78's Contracts))
would be treated as having imputed interest, market discount, or both. In
addition, it is not clear whether use of a prepayment assumption is required in
computing OID. If the IRS were to require that OID be computed on a
Contract-by-Contract basis, or that a prepayment assumption be used, the
character and timing of a Certificate Owner's income could be adversely
affected. Because under the stripped bond rules each sale of a Certificate
results in a recalculation of OID, a Certificate Owner technically will not be
subject to the market discount provisions of the Code with respect to Stripped
Contracts.
 
     The tax treatment of a Stripped Contract (or the Stripped Contracts in the
aggregate) will depend upon whether the amount of OID on the Contract or
Contracts is less than a statutorily defined de minimis amount. In general,
under the Section 1286 Regulations the amount of OID on a Stripped Contract will
be de minimis if it is less than 1/4 of one percent for each full year of
weighted average maturity remaining after the purchase date until the maturity
of the Contract (although it is not clear whether expected prepayments are taken
into account). If the amount of OID is de minimis under this rule, a Stripped
Contract would not be treated as having OID. The actual amount of discount on a
Stripped Contract would be includible in income as principal payments are
received on the Contract, in the proportion that each principal payment bears to
the total principal amount of the Contract. If the IRS were to require the use
of the Origination Actuarial Method, the OID on a Contract would not be de
minimis.
 
     If the OID on a Contract (or Contracts) is not treated as being de minimis,
a Certificate Owner will be required to include in income any OID as it accrues
on a daily basis, regardless of when cash payments are received, using a method
reflecting a constant yield to maturity on the Contract (or Contracts). Accrued
OID would increase a Certificate Owner's tax basis in the Certificate (and the
applicable Contracts). Distributions of principal and other items attributable
to accrued OID (other than payments of interest on the Contracts at      %)
would reduce a Certificate Owner's tax basis. Application of the OID rules,
particularly if a prepayment assumption is required and the Contracts are not
aggregated, would be complex and could significantly affect the timing of
inclusion of income on a Certificate.
 
   
     The Trustee intends to account for OID, if any, reportable by holders of
Certificates by reference to the price paid for a Certificate by an initial
purchaser, although the amount of OID will differ for subsequent purchasers.
Such subsequent purchasers should consult their tax advisors regarding the
proper calculation of OID on the interest in Contracts represented by a
Certificate.
    
 
     Premium. In the event that a Contract is treated as purchased at a premium
(i.e., its Purchase Price exceeds the portion of the remaining principal balance
of such Contract allocable to the Certificate Owner), such premium will be
amortizable by the Certificate Owner as an offset to interest income (with a
corresponding reduction in the Certificate Owner's basis) under a constant
yield-to-maturity method over the term of the Contract if an election under
Section 171 of the Code is made with respect to the interests in the Contracts
represented by the Certificates or was previously in effect. Any such election
will also apply to all debt instruments held by the Certificate Owner during the
year in which the election is made and all debt instruments acquired thereafter.
 
YIELD SUPPLEMENT AMOUNTS
 
   
     The proper federal income tax characterization of the Yield Supplement
Amounts is not clear. If the right to receive Yield Supplement Amounts is
treated as a separate asset purchased by each Certificate Owner, a portion of
the purchase price paid by each Certificate Owner for a Certificate should be
allocated to such right (such portion, the "Allocated Amount"). The Allocated
Amount may be treated as a loan made by the Certificate Owner to the Seller, in
which case a portion of the Yield Supplement Amounts should be treated as
interest includible in income as accrued or received and the remainder should be
treated as a return of the principal amount of the deemed loan. Alternatively,
if the entire amount of each Yield Supplement
    
 
                                       48
<PAGE>   50
 
   
Amount should be included in income as accrued or received, the Certificate
Owner should be entitled to amortize the Allocated Amount. No assurance can be
given, however, that either of these two characterizations will be accepted by
the IRS.
    
 
SALE OF A CERTIFICATE
 
     If a Certificate is sold, gain or loss will be recognized equal to the
difference between the amount realized on the sale and the Certificate Owner's
adjusted basis in the Contracts and any other assets held by the Trust. A
Certificate Owner's adjusted basis will equal the Certificate Owner's cost for
the Certificate, increased by any discount previously included in income, and
decreased by any deduction previously allowed for accrued premium and by the
amount of principal payments previously received on the Contracts. Any gain or
loss not attributable to accrued interest or accrued market discount will be
capital gain or loss if the Certificate was held as a capital asset.
 
FOREIGN CERTIFICATE OWNER
 
   
     Interest attributable to Contracts which is payable to a foreign
Certificate Owner that is not engaged in a trade or business in the United
States will generally not be subject to the 30% withholding tax generally
imposed with respect to such payments, provided that such Certificate Owner
fulfills certain certification requirements. Under such certification
requirements, the Certificate Owner must certify, under penalties of perjury,
that it is not a "United States person" and it is the beneficial owner of the
Certificates, and must provide its name and address. For this purpose, "United
States person" means a citizen or resident of the United States, a corporation,
partnership, or other entity created or organized in or under the laws of the
United States or any political subdivision thereof, or an estate or trust the
income of which is includible in gross income for United States Federal income
tax purposes, regardless of its source (except, with respect to the tax year of
any trust that begins after December 31, 1996, a United States person shall also
mean a trust whose administration is subject to the primary supervision of a
United States court and which has one or more United States fiduciaries who have
the authority to control all substantial decisions of the trust).
    
 
BACKUP WITHHOLDING
 
     Payments made on the Certificates and proceeds from the sale of
Certificates will not be subject to a "backup" withholding tax of 31% unless, in
general, the Certificate Owner fails to comply with certain reporting procedures
and is not an exempt recipient under applicable provisions of the Code.

                              ERISA CONSIDERATIONS
 
     The Employee Retirement Income Security Act of 1974, as amended ("ERISA"),
imposes certain restrictions on employee benefit plans ("Plans") subject to
ERISA and persons who have certain specified relationship to such Plans
("Parties in Interest"). ERISA also imposes certain duties on persons who are
fiduciaries of Plans subject to ERISA and prohibits certain transactions between
a Plan and Parties in Interest with respect to such Plans. Under ERISA, any
person who exercises any authority or control respecting the management or
disposition of the assets of a Plan is considered to be a fiduciary of such Plan
(subject to certain exceptions not here relevant.)
 
     The Department of Labor ("DOL") has issued a final regulation (29 C.F.R.
Section 2510.3-101) concerning the definition of what constitutes the assets of
a Plan (the "Plan Asset Regulation"). This regulation provides that, as a
general rule, the underlying assets and properties of corporations,
partnerships, grantor trusts and certain other entities in which a Plan (which
is subject to ERISA) makes an "equity" investment will be deemed for purposes of
ERISA to be assets of the investing Plan unless certain exceptions apply. The
Plan Asset Regulation contains certain exceptions to this general rule.
Accordingly if a Plan purchases the Certificates, the Trust could be deemed to
hold plan assets unless one of the exceptions under the Plan Assets Regulation
is applicable to the Trust.
 
   
     Under the terms of the Plan Asset Regulation, if the Trust were deemed to
hold Plan assets by reason of a Plan's investment in a Certificate, such Plan
assets would include an undivided interest in the Trust and Contracts underlying
the Trust and any other assets held by the Trust. In such an event, the persons
providing services with respect to the assets of the Trust, including the
Contracts, may be subject to the fiduciary responsibility provisions of Title I
of ERISA. In addition, those persons and certain other persons, including
Obligors on the receivables held in the Trust, may be subject to the prohibited
transaction provisions of ERISA and Section 4975 of the Code with respect to
certain transactions involving such assets or the Certificates. Accordingly, the
Certificates may not be purchased by or on behalf of Plans.
    
 
   
                                  UNDERWRITING
    
 
     Subject to the terms and conditions set forth in the Underwriting Agreement
dated December   , 1996 (the "Underwriting Agreement") between the Seller and
Merrill Lynch, Pierce, Fenner & Smith Incorporated (the "Underwriter"), the
Seller has agreed to sell to the Underwriter, and the Underwriter has agreed to
purchase the entire principal amount of the Certificates.
 
     The Seller has been advised by the Underwriter that it proposes initially
to offer the Certificates to the public at the public offering price set forth
on the cover page of this prospectus and to certain dealers at such price less a
concession not in excess of      % of the principal amount thereof. The
Underwriter may allow, and such dealers may reallow, a discount not in excess of
     % of the principal amount of the Certificates on sales to certain other
dealers. After the initial public offering, the public offering price of the
Certificates and such concession and discount may be changed. The Underwriter is
obligated to purchase and pay for all of the Certificates if any Certificates
are purchased. The Underwriter currently intends, but is not obligated, to make
a market in the Certificates.
 
     The Seller and Onyx have agreed to indemnify the Underwriter against
certain liabilities, including liabilities under applicable securities laws, or
contribute to payments the Underwriter may be required to make in respect
thereof.
 
                                 LEGAL MATTERS
 
   
     Certain matters with respect to the legality of the Certificates and with
respect to the federal income tax matters discussed under "Certain Tax
Consequences" will be passed upon for the Seller by Brobeck, Phleger & Harrison
LLP, Newport Beach, California. As of November 30, 1996, members of Brobeck,
Phleger & Harrison beneficially owned 22,899 shares of Onyx's Common Stock.
Bruce R. Hallett, a member of Brobeck, Phleger & Harrison LLP is Corporate
Secretary and a director of Onyx. Certain legal matters with respect to

                        DECEMBER 31, 1995, 1994 AND 1993
 
                  (WITH INDEPENDENT AUDITORS' REPORT THEREON)

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors
  CAPITAL MARKETS ASSURANCE CORPORATION:
 
     We have audited the accompanying balance sheets of Capital Markets
Assurance Corporation as of December 31, 1995 and 1994 and the related
statements of income, stockholder's equity and cash flows for each of the years
in the three-year period ended December 31, 1995. These financial statements are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1995 AND 1994
 
1)  BACKGROUND
 
     Capital Markets Assurance Corporation ("CapMAC" or "the Company") is a New
York-domiciled monoline stock insurance company which engages only in the
business of financial guaranty and surety insurance. CapMAC is a wholly-owned
subsidiary of CapMAC Holdings Inc. ("Holdings"). CapMAC is licensed in all 50
states in addition to the District of Columbia, the Commonwealth of Puerto Rico
and the territory of Guam. CapMAC insures structured asset-backed, corporate,
municipal and other financial obligations in the U.S. and international capital
markets. CapMAC also provides financial guaranty reinsurance for structured
asset-backed, corporate, municipal and other financial obligations written by
other major insurance companies.
 
     CapMAC's claims-paying ability is rated "Aaa" by Moody's Investors Service,
Inc. ("Moody's"), "AAA" by S&P Ratings Group ("S&P"), "AAA" by Duff & Phelps
Credit Rating Co. ("Duff & Phelps"), and "AAA" by Nippon Investors Service,
Inc., a Japanese rating agency. Such ratings reflect only the views of the
respective rating agencies, are not recommendations to buy, sell or hold
securities and are subject to revision or withdrawal at any time by such rating
agencies.
 
2)  SIGNIFICANT ACCOUNTING POLICIES
 
     Significant accounting policies used in the preparation of the accompanying
financial statements are as follows:
 
     a)   BASIS OF PRESENTATION
 
        The accompanying financial statements are prepared on the basis of
        generally accepted accounting principles ("GAAP"). Such accounting
        principles differ from statutory reporting practices used by insurance
        companies in reporting to state regulatory authorities.
 
        The preparation of financial statements in conformity with generally
        accepted accounting principles requires management to make estimates and
        assumptions that affect the reported amounts of assets and liabilities
        and the disclosure of contingent assets and liabilities at the date of
        the financial statements and the reported amounts of revenues and
        expenses during the reporting period. Management believes the most
        significant estimates relate to deferred acquisition costs, reserve for
        losses and loss adjustment expenses and disclosures of financial
        guarantees outstanding. Actual results could differ from those
        estimates.
 
     b)   INVESTMENTS
 
        At December 31, 1993, the Company adopted the provisions of Statement of
        Financial Accounting Standards ("SFAS") No. 115, "Accounting for Certain
        Investments in Debt and Equity Securities." Under SFAS No. 115, the
        Company can classify its debt and marketable equity securities in one of
        three categories: trading, available-for-sale, or held-to-maturity.
        Trading securities are bought and held principally for the purpose of
        selling them in the near term. Held-to-maturity securities are those
        securities in which the Company has the ability and intent to hold the
        securities until maturity. All other securities not included in trading
        or held-to-maturity are classified as available-for-sale. As of December
        31, 1995 and 1994, all of the Company's securities have been classified
        as available-for-sale.
 
        Available-for-sale securities are recorded at fair value. Fair value is
        based upon quoted market prices. Unrealized holding gains and losses,
        net of the related tax effect, on available-for-sale securities are
        excluded from earnings and are reported as a separate component of
        stockholder's
 
                                       F-7
<PAGE>   63
 
                     CAPITAL MARKETS ASSURANCE CORPORATION
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
        equity until realized. Transfers of securities between categories are
        recorded at fair value at the date of transfer.
 
        A decline in the fair value of any available-for-sale security below
        cost that is deemed other than temporary is charged to earnings
        resulting in the establishment of a new cost basis for the security.
 
        Short-term investments are those investments having a maturity of less
        than one year at purchase date. Short-term investments are carried at
        amortized cost which approximates fair value.
 
        Premiums and discounts are amortized or accreted over the life of the
        related security as an adjustment to yield using the effective interest
        method. Dividend and interest income are recognized when earned.
        Realized gains and losses are included in earnings and are derived using
        the FIFO (first-in, first-out) method for determining the cost of
        securities sold.
 
     C)   REVENUE RECOGNITION
 
        Premiums which are payable monthly to CapMAC are reflected in income
        when due, net of amounts payable to reinsurers. Premiums which are
        payable quarterly, semi-annually or annually are reflected in income,
        net of amounts payable to reinsurers, on an equal monthly basis over the
        corresponding policy term. Premiums that are collected as a single
        premium at the inception of the policy and have a term longer than one
        year are earned, net of amounts payable to reinsurers, by allocating
        premium to each bond maturity based on the principal amount and earning
        it straight-line over the term of each bond maturity. For the year ended
        December 31, 1995, 91% of net premiums earned were attributable to
        premiums payable in installments and 9% were attributable to premiums
        collected on an upfront basis.
 
     D)   DEFERRED ACQUISITION COSTS
 
        Certain costs incurred by CapMAC, which vary with and are primarily
        related to the production of new business, are deferred. These costs
        include direct and indirect expenses related to underwriting, marketing
        and policy issuance, rating agency fees and premium taxes. The deferred
        acquisition costs are amortized over the period in proportion to the
        related premium earnings. The actual amount of premium earnings may
        differ from projections due to various factors such as renewal or early
        termination of insurance contracts or different run-off patterns of
        exposure resulting in a corresponding change in the amortization pattern
        of the deferred acquisition costs.
 
     E)   RESERVE FOR LOSSES AND LOSS ADJUSTMENT EXPENSES
 
        The reserve for losses and loss adjustment expenses consists of a
        Supplemental Loss Reserve ("SLR") and a case basis loss reserve. The SLR
        is established based on expected levels of defaults resulting from
        credit failures on currently insured issues. This SLR is based on
        estimates of the portion of earned premiums required to cover those
        claims.
 
        A case basis loss reserve is established for insured obligations when,
        in the judgement of management, a default in the timely payment of debt
        service is imminent. For defaults considered temporary, a case basis
        loss reserve is established in an amount equal to the present value of
        the anticipated defaulted debt service payments over the expected period
        of default. If the default is judged not to be temporary, the present
        value of all remaining defaulted debt service payments is recorded as a
        case basis loss reserve. Anticipated salvage recoveries are considered
        in establishing case basis loss reserves when such amounts are
        reasonably estimable.
 
        Management believes that the current level of reserves is adequate to
        cover the estimated liability for claims and the related adjustment
        expenses with respect to financial guaranties issued by
 
                                       F-8
<PAGE>   64

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
        CapMAC. The establishment of the appropriate level of loss reserves is
        an inherently uncertain process involving numerous estimates and
        subjective judgments by management, and therefore there can be no
        assurance that losses in CapMAC's insured portfolio will not exceed the
        loss reserves.
 
     f)    DEPRECIATION
 
        Leasehold improvements, furniture and fixtures are being depreciated
        over the lease term or useful life, whichever is shorter, using the
        straight-line method.
 
     g)   INCOME TAXES
 
        Deferred income taxes are provided with respect to temporary differences
        between the financial statement and tax basis of assets and liabilities
        using enacted tax rates in effect for the year in which the differences
        are expected to reverse.
 
     h)   RECLASSIFICATIONS
 
        Certain prior year balances have been reclassified to conform to the
        current year presentation.
 
3)  INSURED PORTFOLIO
 
     At December 31, 1995 and 1994, the principal amount of financial
obligations insured by CapMAC was $16.9 billion and $11.6 billion, respectively,
and net of reinsurance (net principal outstanding), was $12.6 billion and $9.4
billion, respectively, with a weighted average life of 6.0 years and 5.0 years,
respectively. CapMAC's insured portfolio was broadly diversified by geographic
distribution and type of insured obligations, with no single insured obligation
in excess of statutory single risk limits, after giving effect to any
reinsurance and collateral, which are a function of CapMAC's statutory qualified
capital (the sum of statutory capital and surplus and mandatory contingency
reserve). At December 31, 1995 and 1994, the statutory qualified capital was
approximately $240 million and $170 million, respectively.

</TABLE>
 
     At December 31, 1995, approximately 85% of CapMAC's insured portfolio was
comprised of structured asset-backed transactions. Under these structures, a
pool of assets covering at least 100% of the principal amount guaranteed under
its insurance contract is sold or pledged to a special purpose bankruptcy remote
entity. CapMAC's primary risk from such insurance contracts is the impairment of
cash flows due to delinquency or loss on the underlying assets. CapMAC,
therefore, evaluates all the factors affecting past and future asset performance
by studying historical data on losses, delinquencies and recoveries of the
underlying assets. Each transaction is reviewed to ensure that an appropriate
legal structure is used to protect against the bankruptcy risk of the originator
of the assets. Along with the legal structure, an additional level of first loss
protection is also created to protect against losses due to credit or dilution.
This first level of loss protection is usually available from reserve funds,
excess cash flows, overcollateralization, or recourse to a third party. The

level of first loss protection depends upon the historical losses and dilution
of the underlying assets, but is typically several times the normal historical
loss experience for the underlying type of assets.
 
     During 1995, the Company sold without recourse its interest in potential
cash flows from transactions included in its insured portfolio and recognized
$2,200,000 of income which has been included in other income in the accompanying
financial statements.
 
     The following entities each accounted for, through referrals and otherwise,
10% or more of total revenues for each of the periods presented:

6)  EMPLOYEE BENEFITS
 
     On June 25, 1992, CapMAC entered into a Service Agreement with CapMAC
Financial Services, Inc. ("CFS"), which was then a newly formed wholly-owned
subsidiary of Holdings. Under the Service Agreement, CFS has agreed to provide
various services, including underwriting, reinsurance, data processing and other
services to CapMAC in connection with the operation of CapMAC's insurance
business. CapMAC pays CFS an arm's length fee for providing such services, but
not in excess of CFS's cost for such services. CFS incurred, on behalf of
CapMAC, total compensation expenses, excluding bonuses, of $13,484,000,
$11,081,000 and $9,789,000 in 1995, 1994 and 1993, respectively.
 
     CFS maintains an incentive compensation plan for its employees. The plan is
an annual discretionary bonus award based upon Holdings' and an individual's
performance. CFS also has a health and welfare plan and a 401(k) plan to cover
substantially all of its employees. CapMAC reimburses CFS for all out-of-pocket
expenses incurred by CFS in providing services to CapMAC, including awards given
under the incentive compensation plan and benefits provided under the health and
welfare plan. For the years ended December 31, 1995, 1994 and 1993, the Company
had provided approximately $7,804,000, $5,253,000 and $3,528,000, respectively,
for the annual discretionary bonus plan.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     One June 25, 1992, certain officers of CapMAC were granted 182,633
restricted stock units ("RSU") at $13.33 a share in respect of certain deferred
compensation. On December 7, 1995, the RSU's were converted to cash in the
amount of approximately $3.7 million, and such officers agreed to defer receipt
of such cash amount in exchange for receiving the same number of new shares of
restricted stock of Holdings as the number of RSU's such officers previously
held. The cash amount will be held by Holdings and invested in accordance with
certain guidelines. Such amount, including the investment earnings thereon, will
be paid to each officer upon the occurrence of certain events but no later than
December, 2000.
 
7)  EMPLOYEE STOCK OWNERSHIP PLAN
 
     On June 25, 1992, Holdings adopted an Employee Stock Ownership Plan
("ESOP") to provide its employees the opportunity to obtain beneficial interests
in the stock of Holdings through a trust (the "ESOP Trust"). The ESOP Trust
purchased 750,000 shares at $13.33 per share of Holdings' stock. The ESOP Trust
financed its purchase of common stock with a loan from Holdings in the amount of
$10 million. The ESOP loan is evidenced by a promissory note delivered to
Holdings. An amount representing unearned employee compensation, equivalent in
value to the unpaid balance of the ESOP loan, is recorded as a deduction from
stockholder's equity (unallocated ESOP shares).
 
     CFS is required to make contributions to the ESOP Trust, which enables the
ESOP Trust to service its loan to Holdings. The ESOP expense is calculated using
the shares allocated method. Shares are released for allocation to the
participants and held in trust for the employees based upon the ratio of the
current year's principal and interest payment to the sum of principal and
interest payments estimated over the life of the loan. As of December 31, 1995
approximately 262,800 shares were allocated to the participants. Compensation
expense related to the ESOP was approximately $2,087,000, $2,086,000 and
$1,652,000 for the years ended December 31, 1995, 1994 and 1993, respectively.
 
8)  RESERVE FOR LOSSES AND LOSS ADJUSTMENT EXPENSES
 
     The reserve for losses and loss adjustment expenses consists of a case
basis loss reserve and the SLR.
 
     In 1995 CapMAC incurred its first claim on a financial guaranty policy.
Based on its current estimate, the Company expects the aggregate amount of
claims and related expenses not to exceed $2.7 million, although no assurance
can be given that such claims and related expenses will not exceed that amount.
Such loss amount was covered through a recovery under a quota share reinsurance
agreement of $0.2 million and a reduction in the SLR of $2.5 million. The
portion of such claims and expenses not covered under the quota share agreement
is being funded through payments to CapMAC from the Lureco Trust Account (see
note 12).

9)  INCOME TAXES
 
     Pursuant to a tax sharing agreement with Holdings, the Company is included
in Holdings' consolidated U.S. Federal income tax return. The Company's annual
Federal income tax liability is determined by computing its pro rata share of
the consolidated group Federal income tax liability.
 
     Total income tax expense differed from the amount computed by applying the
U.S. Federal income tax rate of 35% in 1995 and 34% in 1994 and 1993:

10) INSURANCE REGULATORY RESTRICTIONS
 
     CapMAC is subject to insurance regulatory requirements of the State of New
York and other states in which it is licensed to conduct business. Generally,
New York insurance laws require that dividends be paid from earned surplus and
restrict the amount of dividends in any year that may be paid without obtaining
approval for such dividends from the Superintendent of Insurance to the lower of
(i) net investment income as defined or (ii) 10% of statutory surplus as of
December 31 of the preceding year. No dividends were paid by CapMAC to Holdings
during the years ended December 31, 1995, 1994 and 1993. No dividends could be
paid during these periods because CapMAC had negative earned surplus. Statutory
surplus at December 31, 1995 and 1994 was approximately $195,018,000 and
$139,739,000, respectively. Statutory surplus differs from stockholder's equity
determined under GAAP principally due to the mandatory contingency reserve
required for statutory accounting purposes and differences in accounting for
investments, deferred acquisition costs, SLR and deferred taxes provided under
GAAP. Statutory net income was $9,000,000, $4,543,000 and $4,528,000 for the
years ended December 31, 1995, 1994 and 1993, respectively. Statutory net income
differs from net income determined under GAAP principally due to deferred
acquisition costs, SLR and deferred income taxes.

     On January 1, 1988, the Company assumed from Citibank, N.A. the obligations
of a sublease agreement for space occupied in New York. On November 21, 1993,
the sublease was terminated and a new lease was negotiated which expires on
November 20, 2008. CapMAC has a lease agreement for its London office beginning
October 1, 1992 and expiring October 1, 2002. As of December 31, 1995, future
minimum payments under the lease agreements are as follows:

$2,065,000, respectively.
 
     CapMAC has available a $100,000,000 standby corporate liquidity facility
(the "Liquidity Facility") provided by a consortium of banks, headed by Bank of
Montreal, as agent, which is rated "A-1+" and "P-1" by S&P and Moody's,
respectively. Under the Liquidity Facility, CapMAC will be able, subject to
satisfying certain conditions, to borrow funds from time to time in order to
enable it to fund any claim payments or payments made in settlement or
mitigation of claim payments under its insurance contracts. For the years ended
December 31, 1995, 1994 and 1993, no draws had been made under the Liquidity
Facility.
 
12) REINSURANCE
 
     In the ordinary course of business, CapMAC cedes exposure under various
treaty, pro rata and excess of loss reinsurance contracts primarily designed to
minimize losses from large risks and protect the capital and surplus of CapMAC.
 
     The effect of reinsurance on premiums written and earned was as follows:

     Although the reinsurance of risk does not relieve the ceding insurer of its
original liability to its policyholders, it is the industry practice of insurers
for financial statement purposes to treat reinsured risks as though they were
risks for which the ceding insurer was only contingently liable. A contingent
liability exists with respect to the aforementioned reinsurance arrangements
which may become a liability of CapMAC in the event the reinsurers are unable to
meet obligations assumed by them under the reinsurance contracts. At

December 31, 1995 and 1994, CapMAC had ceded loss reserves of $69,000 and $0,
respectively, and had ceded unearned premiums of $13,171,000 and $5,551,000,
respectively.
 
     In 1994, CapMAC entered into a reinsurance agreement (the "Lureco Treaty")
with Luxembourg European Reinsurance LURECO S.A. ("Lureco"), a European-based
reinsurer. The agreement is renewable annually at the Company's option, subject
to satisfying certain conditions. The agreement reinsured and indemnified the
Company for any loss incurred by CapMAC during the agreement period up to the
limits of the agreement. The Lureco Treaty provides that the annual reinsurance
premium payable by CapMAC to Lureco, after deduction of the reinsurer's fee
payable to Lureco, be deposited in a trust account (the "Lureco Trust Account")
to be applied by CapMAC, at its option, to offset losses and loss expenses
incurred by CapMAC in connection with incurred claims. Amounts on deposit in the
Lureco Trust Account which have not been applied against claims are
contractually due to CapMAC at the termination of the treaty.
 
     The premium deposit amounts in the Lureco Trust Account have been reflected
as assets by CapMAC during the term of the agreement. Premiums in excess of the
deposit amounts have been recorded as ceded premiums in the statements of
income. In the 1994 policy year, the agreement provided $5 million of loss
coverage in excess of the premium deposit amounts of $2 million retained in the
Lureco Trust Account. No losses were applied against the Lureco Trust Account or
ceded to the Lureco Treaty in 1994. The agreement was renewed for the 1995
policy year and provides $5 million of loss coverage in excess of the premium
deposit amount of $4.5 million retained in the Lureco Trust Account. Additional
coverage is provided for losses incurred in excess of 200% of the net premiums
earned up to $4 million for any one agreement year. In September 1995, a claim
of approximately $2.5 million on an insurance policy was applied against the
Lureco Trust Account.
 
     In addition to its capital (including statutory contingency reserves) and
other reinsurance available to pay claims under its insurance contracts, on June
25, 1992, CapMAC entered into a Stop Loss Reinsurance Agreement (the "Stop-loss
Agreement") with Winterthur Swiss Insurance Company ("Winterthur") which is
rated "AAA" by S&P and "Aaa" by Moody's. At the same time, CapMAC and Winterthur
also entered into a Quota Share Reinsurance Agreement (the "Winterthur Quota
Share Agreement") pursuant to which Winterthur had the right to reinsure on a
quota share basis 10% of each policy written by CapMAC.
 
     The Winterthur Stop-loss Agreement had an original term of seven years and
was renewable for successive one-year periods. In April 1995, Winterthur
notified CapMAC that it was canceling the Winterthur Stop-loss Agreement and the
Winterthur Quota Share Agreement effective June 30, 1996.
 
     CapMAC elected to terminate the Winterthur Stop-loss Agreement effective
November 30, 1995 and, on the same date, entered into a Stop-loss Reinsurance
Agreement with Mitsui Marine (the "Mitsui Stop-loss Agreement"). Under the
Mitsui Stop-loss Agreement, Mitsui Marine would be required to pay any losses in
excess of $100 million in the aggregate incurred by CapMAC during the term of
the Mitsui Stop-loss Agreement on the insurance policies in effect on December
1, 1995 and written during the one-year period thereafter, up to an aggregate
limit payable under the Mitsui Stop-loss Agreement of $50 million. The Mitsui
Stop-loss Agreement has a term of seven years and is subject to early
termination by CapMAC in certain circumstances.
 
     The Winterthur Quota Share Agreement was canceled November 30, 1995. On
January 1, 1996, CapMAC will reassume the liability, principally unearned
premium, for all policies reinsured by Winterthur. As a result, CapMAC will
reassume approximately $1.4 billion of principal insured by Winterthur as of
December 31, 1995. In connection with the commutation, Winterthur will return
the unearned premiums as of December 31, 1995, net of ceding commission and
federal excise tax. Such amount is expected to total approximately $2.0 million.

</TABLE>
 
     The following methods and assumptions were used to estimate the fair value
of each class of financial instruments summarized above:
 
INVESTMENTS
 
     The fair values of fixed maturities and mutual funds are based upon quoted
market prices. The fair value of short-term investments approximates amortized
cost.
 
FINANCIAL GUARANTEES OUTSTANDING
 
     The fair value of financial guarantees outstanding consists of (1) the
current unearned premium reserve, net of prepaid reinsurance and (2) the fair
value of installment revenue which is derived by calculating the present value
of the estimated future cash inflow to CapMAC of policies in force having
installment premiums, net of amounts payable to reinsurers, at a discount rate
of 7% at December 31, 1995 and 1994. The amount calculated is equivalent to the
consideration that would be paid under market conditions prevailing at the
reporting dates to transfer CapMAC's financial guarantee business to a third
party under reinsurance and other agreements. Ceding commission represents the
expected amount that would be paid to CapMAC to compensate CapMAC for
originating and servicing the insurance contracts. In constructing estimated
future cash inflows, management makes assumptions regarding prepayments for
amortizing asset-backed securities which are consistent with relevant historical
experience. For revolving programs, assumptions are made regarding program
utilization based on discussions with program users. The amount of installment
premium actually realized by the Company could be reduced in the future due to
factors such as early termination of insurance contracts, accelerated
prepayments of underlying obligations or lower than anticipated utilization of
insured structured programs, such as commercial paper conduits. Although
increases in future installment revenue due to renewals of existing insurance
contracts historically have been greater than reductions in future installment
revenue due to factors such as those described above, there can be no assurance
that future circumstances might not cause a net reduction in installment
revenue, resulting in lower revenues.
 
14) CAPITALIZATION
 
     The Company's certificate of incorporation authorizes the issuance of
15,000,000 shares of common stock, par value $1.00 per share. Authorized, issued

                    NOTES TO UNAUDITED FINANCIAL STATEMENTS
                               SEPTEMBER 30, 1996


1.       BACKGROUND

         Capital Markets Assurance Corporation ("CapMAC") is a New
         York-domiciled monoline stock insurance company which engages only in
         the business of financial guaranty and surety insurance. CapMAC is a
         wholly-owned subsidiary of CapMAC Holdings Inc. ("Holdings"). CapMAC is
         licensed in all 50 states in addition to the District of Columbia, the
         Commonwealth of Puerto Rico and the territory of Guam. CapMAC insures
         structured asset-backed, corporate, municipal and other financial
         obligations in the U.S. and international capital markets. CapMAC also
         provides financial guaranty reinsurance for structured asset-backed,
         corporate, municipal and other financial obligations written by other
         major insurance companies.

         CapMAC's claims-paying ability is rated triple-A by Moody's Investors
         Service, Inc., Standard & Poor's Ratings Services, Duff & Phelps Credit
         Rating Co., and Nippon Investors Service, Inc., a Japanese rating
         agency. Such ratings reflect only the views of the respective rating
         agencies, are not recommendations to buy, sell or hold securities and
         are subject to revision or withdrawal at any time by such rating
         agencies.

2.       BASIS OF PRESENTATION

         CapMAC's unaudited interim financial statements have been prepared on
         the basis of generally accepted accounting principles and, in the
         opinion of management, reflect all adjustments necessary for a fair
         presentation of the CapMAC's financial condition, results of operations
         and cash flows for the periods presented. The results of operations for
         the nine months ended September 30, 1996 may not be indicative of the
         results that may be expected for the full year ending December 31,
         1996. These financial statements and notes should be read in
         conjunction with the financial statements and notes included in the
         audited financial statements of CapMAC as of December 31, 1995 and
         1994, and for each of the years in the three-year period ended December
         31, 1995.

3.       RECLASSIFICATIONS

         Certain prior period balances have been reclassified to conform to the
         current period presentation.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Under Section 145 of the Delaware General Corporation Law ("Delaware Law")
Onyx Acceptance Financial Corporation (the "Company") has broad powers to
indemnify its directors and officers against liabilities they may incur in such
capacities, including liabilities under the Securities Act of 1933, as amended
(the "Securities Act"). The Company's Bylaws (the "Bylaws") (Exhibit 3.2 hereto)
provide that the Company shall indemnify its directors and officers to the
fullest extent permitted by law and requires the Company to advance litigation
expenses upon receipt by the Company of an undertaking by the director or
officer to repay such advances if it is ultimately determined that the director
is not entitled to indemnification. The Bylaws further provide that rights
conferred under such Bylaws shall not be deemed to be exclusive of any other
right such persons may have or acquire under any bylaw, agreement, vote of
stockholders or disinterested directors, or otherwise.
 
     The Certificate of Incorporation (the "Certificate of Incorporation")
(Exhibit 3.1 hereto) provides that, pursuant to Delaware Law, its directors
shall not be liable for monetary damages for breach of the directors' fiduciary
duty of care to the Company and its stockholders. This provision in the
Certificate of Incorporation does not eliminate the duty of care, and in
appropriate circumstances equitable remedies such as injunctive or other forms
of non-monetary relief will remain available under Delaware Law. In addition,
each director will continue to be subject to liability for breach of the
director's duty of loyalty to the Company for acts or omissions not in good
faith or involving intentional misconduct, for knowing violations of law, for
actions leading to improper personal benefits to the director, and for payment
of dividends or approval of stock repurchases or redemptions that are unlawful
under Delaware Law. The provision also does not affect a director's
responsibilities under any other law, such as the federal securities laws or
state or federal environmental laws. The Certificate of Incorporation further
provides that the Company shall indemnify its directors and officers to the
fullest extent permitted by law, and requires the Company to advance litigation
expenses in the case of stockholder derivative actions or other actions, against
an undertaking by the director to repay such advances if it is ultimately
determined that the director is not entitled to indemnification. The Certificate
of Incorporation also provides that rights conferred under such Certificate of
Incorporation shall not be deemed to be exclusive of any other right such
persons may have or acquire under any statute, the Certificate of Incorporation,
the Bylaws, agreement, vote of stockholders or disinterested directors, or
otherwise.
 
     The Company plans to acquire a directors' and officers' liability insurance
policy that, subject to the terms and conditions of the policy, insures the
directors and officers of the Company against losses arising from any wrongful
act (as defined by the policy) in his or her capacity as a director or officer.
The policy reimburses the Company for amounts which the Company lawfully
indemnifies or for which it is required or permitted by law to indemnify its
directors and officers.
 
     In addition, the Company expects to enter into agreements to indemnify its
directors and certain of its officers in addition to indemnification provided
for in the Certificate of Incorporation and Bylaws. These
 
                                      II-1
<PAGE>   82
 
agreements will, among other things, indemnify the Company's directors and
certain of its officers for certain expenses (including attorneys' fees),
judgments, fines and settlement amounts incurred by such person in any action or
proceeding, including any action by or in the right of the Company, on account
of services as a director or officer of the Company or as a director or officer
of any subsidiary of the Company, or as a director or officer of any other
company or enterprise that the person provides services to at the request of the
Company.
 
     The Underwriting Agreement provides for indemnification by the Company of
the Underwriters, for certain liabilities rising under the Securities Act or
otherwise. It also provides, in certain limited instances, for indemnification
by the Underwriters of the Company with respect to information furnished by or
on behalf of the Underwriter that are contained in this prospectus or included
as part of this Registration Statement.

ITEM 17. UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes as follows:
 
          (a) To provide to the Underwriter at the closing specified in the
     Underwriting Agreement certificates in such denominations and registered in
     such names as required by the Underwriter to permit prompt delivery to each
     purchaser.
 
          (b) Insofar as indemnification for liabilities arising under the
     Securities Act of 1933 may be permitted to directors, officers and
     controlling persons of the Registrant pursuant to the foregoing provisions,
     or otherwise, the Registrant has been advised that in the opinion of the
     Securities and Exchange Commission such indemnification is against public
     policy as expressed in the Act and is, therefore, unenforceable. In the
     event that a claim for indemnification against such liabilities (other than
     the payment by the Registrant of expenses incurred or paid by a director,
     officer or controlling person of
 
                                      II-2
<PAGE>   83
 
     the Registrant in the successful defense of any action, suit or proceeding)
     is asserted by such director, officer or controlling person in connection
     with the securities being registered, the Registrant will, unless in the
     opinion of its counsel the matter has been settled by controlling
     precedent, submit to a court of appropriate jurisdiction the question
     whether such indemnification by it is against public policy as expressed in
     the Act and will be governed by the final adjudication of such issue.
 
          (c) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this Registration Statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the Registrant pursuant to Rule 424(b) (1) or
     (4) or 497(h) under the Securities Act of 1933 shall be deemed to be part
     of this Registration Statement as of the time it was declared effective.
 
          (d) For the purpose of determining any liability under the Securities
     Act of 1933, each post effective amendment that contains a form of
     prospectus shall be deemed to be a new Registration Statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

Ladies and Gentlemen:

                  1. Introductory. Onyx Acceptance Financial Corporation (the
"Company") proposes to cause Onyx Acceptance Grantor Trust 1996-4 (the "Trust")
to sell to Merrill Lynch, Pierce, Fenner & Smith Incorporated (the
"Underwriter") ____% Auto Loan Pass-Through Certificates, Series 1996-4 (the
"Certificates"). The Certificates will be issued pursuant to a Pooling and
Servicing Agreement between the Company, as Seller, Onyx Acceptance Corporation
as Servicer (the "Servicer" or "Onyx"), Bankers Trust Company as Trustee (the
"Trustee"), dated as of December 1, 1996 (the "Pooling and Servicing
Agreement"). Pursuant to an insurance and reimbursement agreement (the
"Insurance Agreement") among the Company, Onyx Acceptance Corporation, the
Trustee and Capital Markets Assurance Corporation ("the Insurer"), the Insurer
has issued its surety bond (the "Surety Bond") to the Trustee for the benefit of
the Certificateholders guaranteeing timely payment of interest and principal on
the Certificates. In addition, Onyx will enter into a yield supplement agreement
dated as of December 1, 1996 with the Company (the "Yield Supplement Agreement")
which will assign it to the Trust. The assets of the Trust will include, among
other things, (i) a pool (the

 
<PAGE>   2
"Contract Pool") of fixed rate Rule of 78's and Simple Interest Method motor
vehicle retail installment sales contracts (the "Contracts") secured by new and
used automobiles and light-duty trucks (the "Initial Financed Vehicles"),
certain monies due or to become due thereunder on or after the Cutoff Date (as
hereinafter defined), such Contracts to be sold to the Trust by the Seller and
serviced by the Servicer, (ii) the Surety Bond, (iii) security interests in the
Financed Vehicles and the rights to receive proceeds from claims on certain
insurance policies covering the Financed Vehicles or the individual obligors
under each related Contract and the right to proceeds under a blanket insurance
policy, (iv) amounts on deposit in a trust account established for the benefit
of the Certificateholders (the "Pre-Funding Account"), (v) all amounts on
deposit in the Collection Account, (vi) the right of the Company to cause Onyx
to repurchase certain Contracts under certain circumstances and (vii) all
proceeds of the foregoing. The Certificates will be issued in an aggregate
principal amount of $___________ which is equal to the sum of the Original Pool
Balance of the Contracts and the amount on deposit in the Pre-Funding Account as
of the opening of business on December 1, 1996 (the "Cutoff Date"). From time to
time during the Funding Period pursuant to the Purchase Agreement, Only will be
obligated to sell, and the Seller will be obligated to purchase, additional Rule
of 78's and Simple Interest Method retail motor vehicle retail installment sales
contracts (the "Subsequent Contracts" and together with the Initial Contracts
the "Contracts") secured by new and used automobiles and light duty trucks (the
"Subsequent Financed Vehicles" and together with the Initial Financed Vehicles
the "Financed Vehicles"), which Subsequent Contracts will be described in a
transfer certificate delivered by the Company on each Subsequent Transfer Date
(the "Transfer Certificate"). The Subsequent Contracts will be sold from the
Seller to the Trust on the same Business Day such Subsequent Contracts are sold
by Onyx to the Seller (each such date a "Subsequent Transfer Date"). The maximum
aggregate principal amount of Subsequent Contracts to be sold during the Funding
Period by Onyx to the Seller and by the Seller to the Trust is $___________.
Capitalized terms used herein and not otherwise herein defined shall have the
meanings assigned to such terms in the Pooling and Servicing Agreement.

                  The Company hereby agrees with the Underwriter, as follows:

<PAGE>   8
issued by the Commission to the Public Securities Association
(the "No-Action Letter").

                           (ii)     For purposes hereof, "ABS Term Sheets",

tive investors that are required to be filed pursuant to the No-Action Letter
shall bear a legend substantially in the form attached hereto as Exhibit A. The
Company shall have the right to require specific legends or notations to appear

Term Sheets to all recipients of the preliminary versions thereof that indicated
orally to the Underwriter they would purchase all or any portion of the
Certificates, and shall have included such revised ABS Term Sheets (marked, "as
revised") in the materials delivered to the Company pursuant to subsection (iv)
above.

                  (vi) The Company shall not be obligated to file any ABS Term
Sheets that have been determined to contain any material error or omission,
provided that, at the request of the Underwriter, the Company will file ABS Term
Sheets that contain a material error or omission if clearly marked "superseded
by materials dated _______" and accompanied by corrected ABS Term Sheets that
are marked, "supersedes material previously dated _______, as corrected." If,
within the period during which the Prospectus relating to the Certificates is
required to be delivered under the Act, any ABS Term Sheets are determined, in
the reasonable judgment of the Company or the Underwriter, to contain a material
error or omission, the Underwriter shall prepare a corrected version of such ABS
Term Sheets, shall circulate such corrected ABS Term Sheets to all recipients of
the prior versions thereof that either indicated orally to the Underwriter they
would purchase all or any portion of the Certificates, or actually purchased all
or any portion thereof, and shall deliver copies of such corrected ABS Term
Sheets (marked, "as corrected") to the Company for filing with the Commission in
a subsequent post-effective amendment to the Registration Statement (subject to
the Company's obtaining an accountant's comfort letter in respect of such
corrected ABS Term Sheets, which shall be at the expense of the Underwriter).

                  (vii) The Underwriter shall be deemed to have represented as
of the Closing Date, that, except for ABS Term Sheets provided to the Company
pursuant to subsection (iv)

 

                                        9

above, the Underwriter did not provide any prospective investors with any
information in written or electronic form in connection with the offering of the
Certificates that is required to be filed with the Commission in accordance with
the No-Action Letter.

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

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

                                    (i)  The Company will use its best ef-
         forts to cause the Registration Statement, and any amendment thereto,
         if not effective at the Execution Time, to become effective. If the
         Registration Statement has become or becomes effective pursuant to Rule
         430A, or filing of the Prospectus is otherwise required under Rule
         424(b), the Company will file the prospectus, properly completed,
         pursuant to Rule 424(b) within the time period prescribed and will
         provide evidence satisfactory to the Underwriter of such timely filing.
         The Company will advise the Underwriter promptly of any proposal to
         amend or supplement the Registration Statement or the Prospectus, and
         will not effect any such amendment or supplementation to which the
         Underwriter shall reasonably object. The Company will also advise you
         promptly of the effectiveness of any amendment or supplementation of
         the Registration Statement or Prospectus, of any request by the
         Commission for any amendment or supplementation of the Registration
         Statement or the Prospectus or for any additional information, of the
         receipt by the Company of any notification with respect to the
         suspension of qualification of the Certificates for sale in any
         jurisdiction or the initiation or threatening of any proceeding for
         such purpose and of the institution by the Commission of any stop order
         proceeding in respect of the Registration

 

                                       10
<PAGE>   11
         Statement, and will use its best efforts to prevent the issuance of any
         such stop order and to obtain as soon as possible its lifting, if
         issued.

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

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

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

                                    (v)  The Company will cooperate with
         the Underwriter in arranging for the qualification of the Certificates
         for sale and the determination of their eligibility for investment
         under the laws of such jurisdictions as the Underwriter designates and
         will continue such qualifications in effect so long as required for the
         distribution of the Certificates; provided, however, that the Company
         shall not be obligated to qualify to do business in any jurisdiction in
         which it is not currently so qualified or to take any action which
         would subject it to general or

 

                                       11
<PAGE>   12
         unlimited service of process in any jurisdiction where
         it is not now so subject.

                                    (vi)  For a period from the date of
         this Agreement until the retirement of the Certificates, the Company
         will furnish to the Underwriter copies of each certificate and the
         annual statements of compliance delivered to the Trustee pursuant to
         Article III of the Pooling and Servicing Agreement and the annual
         independent public accountant's reports furnished to the Trustee
         pursuant to Article III of the Pooling and Servicing Agreement, as soon
         as practicable after such statements and reports are furnished to the
         Trustee.

                                    (vii) So long as any of the Certificates
         are outstanding, the Company will furnish to you as soon as
         practicable, (A) all documents distributed, or caused to be
         distributed, by the Servicer to the Certificateholders, (B) all
         documents filed, or caused to be filed, by the Company with the
         Commission pursuant to the Securities Act of 1934, as amended, any
         order of the Commission thereunder or pursuant to a "no-action" letter
         from the staff of the Commission and (C) from time to time, such other
         information in the possession of the Company concerning the Trust and
         any other information concerning the Company filed with any
         governmental or regulatory authority which is otherwise publicly
         available as you may reasonably request.

                                    (viii) On or before the Closing Date with
         respect to the Initial Contracts, and on or before each Subsequent
         Transfer Date with respect to the Subsequent Contracts to be
         transferred to the Trust on such date, the Company shall cause its
         computer records relating to the Contracts to be marked to show the
         Trust's absolute ownership of the Contracts and shall cause the
         Servicer to mark its computer records relating to the Contracts to show
         the sale to the Company of the Contracts and its subsequent transfer to
         the Trust, and from and after the Closing Date or such Subsequent
         Transfer Date, as the case may be the Company shall not and shall
         instruct the Servicer not to take any action inconsistent with the
         Trust's ownership of such Contracts, other than as permitted by the
         Pooling and Servicing Agreement.

                            (ix) To the extent, if any, that the rating provided
         with respect to the Certificates by Moody's Investors Service, Inc. and
         Standard & Poor's Corporation is conditional upon the furnishing of
         documents or the taking of any other action by the Company agreed upon
         on or prior to the Closing Date, the Company shall furnish such
         documents and take any such action.

                            (x) The Company shall provide the Underwriter with
         copies of all agreements, certificates, opinions and other documents
         executed or delivered in connection with any Subsequent Closing Date,
         and such other documents relating to any Subsequent Contracts as it may
         reasonably request from the Company.

                            (xi) The Company will file with the Commission a
         post-effective amendment setting forth all ABS Terms Sheet provided to
         the Company by the Underwriter and identified by it as such within the
         time period allotted for such filing pursuant to the No-Action Letter;
         provided, however, that prior to such filing of the ABS Term Sheets
         (other than any ABS Term Sheets that are not based on the Contract Pool
         information) by the Company, the Underwriter must comply with its
         obligations pursuant to Section 4 and the Company must receive a letter
         from Coopers & Lybrand, certified public accountants, satisfactory in
         form and substance to the Company, to the effect that such accountants
         have performed certain specified procedures, all of which have been
         agreed to by the Company, as a result of which they have determined
         that the information included in the ABS Term Sheets (if any), provided
         by the Underwriter to the Company for filing on a post-effective
         amendment pursuant to Section 4 and, if the Company then so specifies,
         this subsection (i), and that the accountants have examined in
         accordance with such agreed upon procedures, is accurate except as to
         such matters that are not deemed by the Company to be material. The
         foregoing letter shall be at the expense of the Underwriter. The
         Company shall file any corrected ABS Term Sheets described in Section
         4(b)(vi) as soon as practicable following receipt thereof.

                  6. Payment of Expenses. The Company will pay all expenses

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

                                    (i)  On or prior to the date of this

         heretofore agreed, which letter shall be in form and substance agreed
         to by the Underwriter.

                                    (ii)  If the Registration Statement has
         not become effective prior to the date of this Agreement, unless the
         Underwriter agrees in writing to a later time, the Registration
         Statement shall have become effective not later than (A) 6:00 p.m., New

         price, if such determination occurred at or prior to 12:00 noon, New
         York City time, on such date or (B) 3:00 p.m. on the business day
         following the day on which the public offering price was determined, if
         such determination occurred after 12:00 noon, New York City time, on

         required pursuant to Rule 424(b), the Prospectus shall be filed in the
         manner and within the time period required by Rule 424(b); and no stop
         order suspending the effectiveness of the Registration Statement shall
         have been issued and no proceedings for that purpose shall have been

         in the reasonable judgment of the Underwriter materially impairs the
         investment quality of the Certificates; (b) any suspension or material
         limitation of trading in securities generally on the New York Stock

         reasonable judgment of the Underwriter, the effect of any such
         outbreak, escalation, calamity or emergency on the United States
         financial markets makes it impracticable or inadvisable to proceed with
         completion of the sale of, and any payment for, the Certificates.

                                            (j) Assuming the authorization,
                  execution and delivery thereof by the Trustee and the Servicer
                  with respect to the Pooling and Servicing Agreement, and by

                  Purchase Agreement and the Yield Supplement Agreement and the
                  Insurer with respect to the Insurance Agreement, each such
                  agreement constitutes the legal, valid and binding agreement
                  of the Company, enforceable against the Company in accordance
                  with its terms, subject, as to enforcement, to (1) the effect
                  of bankruptcy, insolvency, reorganization, moratorium,
                  conservatorship, receivership or other similar laws of
                  general application relating to or affecting creditors' rights
                  generally (2) the application of general principles of equity
                  (regardless of whether such enforceability is considered in a
                  proceeding in equity or at law); and (3) the unenforceability
                  under certain circumstances of provisions indemnifying a party
                  against liability where such indemnification is contrary to
                  public policy;

                                            (k) The Registration Statement
                  became effective under the Act as of the date and time
                  specified in such opinion; after due inquiry, to the best of
                  such counsel's knowledge, no stop order suspending the
                  effectiveness of the Registration Statement has been issued
                  and no proceedings for that purpose have been instituted or
                  are pending or contemplated under the Act; the Registration
                  Statement, and each amendment thereof or supplement thereto as
                  of its Effective Date and the Prospectus as of its date of
                  issuance complied as to form in all material respects with the
                  requirements of the Act and the Rules and Regulations; and
                  such counsel has no reason to believe that either the
                  Registration Statement or the Prospectus or any such amendment
                  thereof or supplement thereto as of its Effective Date or date
                  of issuance, as the case may be, contained any untrue
                  statement of a material fact or omitted to state any material
                  fact required to be stated therein or necessary to make the
                  statements therein, in light of the circumstances under which
                  they were made, not misleading; it being understood that such
                  counsel need express no opinion as to the financial statements
                  or other financial data contained in the Registration
                  Statement or the Prospectus;

                                            (l)  The Certificates, the Pooling
                  and Servicing Agreement, the Purchase Agreement, the Yield
                  Supplement Agreement and the Insurance Agreement conform in
                  all material respects to the descriptions thereof contained in
                  the Registration Statement and the Prospectus;

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

                                            (n) The Trust is not now, and
                  immediately following the sale of the Certificates pursuant to
                  this Agreement will not be, required to be registered under
                  the Investment Company Act of 1940, as amended.

                                    In addition, such counsel shall opine as to
         certain matters relating to the acquisition by the Company of a
         perfected first priority security interest in the vehicles financed by
         motor vehicle installment loans made by the Company.

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

                           (v) The Underwriter shall have received an opinion,
         dated the Closing Date, of Brobeck, Phleger & Harrison, counsel to
         Onyx, substantially to the effect that:

                                            (a) Onyx (1) has been duly

                  executed and delivered, had the power and authority to execute
                  and deliver the Purchase Agreement, the Yield Supplement
                  Agreement, and the Pooling and Servicing Agreement and to
                  consummate the transactions contemplated herein and therein;

                                            (c) No consent, approval, au-
                  thorization or order of, or filing with, any California or
                  federal governmental agency or body or any court is required
                  by Onyx to perform the transactions contemplated by the
                  Pooling and Servicing Agreement, the Yield Supplement
                  Agreement or the Purchase Agreement except for (1) filing of a
                  Uniform Commercial Code financing statement in the State of
                  California with respect to the sale of the Contracts to the
                  Company pursuant to the Purchase Agreement and the transfer of

                  livery and performance by Onyx of the Pooling and Servicing
                  Agreement, the Yield Supplement Agreement or the Purchase
                  Agreement, or the transfer of the Contracts to the Company,
                  has conflicted with or will conflict with, has resulted or
                  will result in a breach, violation or acceleration of any of
                  the terms of, or has constituted or will constitute a default
                  under, the By-Laws or the Certificate of Incorporation of
                  Onyx, as amended, or, to the best of such counsel's knowledge,
                  any rule, order, statute or regulation known to such counsel
                  to be currently applicable to Onyx of any court, regulatory
                  body, administrative agency or governmental body having
                  jurisdiction over Onyx or the terms of any material indenture
                  or other material agreement or instrument known to such
                  counsel to which Onyx is a party or by which it or its
                  properties are bound;

                                            (e) The Pooling and Servicing
                  Agreement, the Yield Supplement Agreement and the

                  Purchase Agreement have each been duly authorized, executed
                  and delivered by Onyx; and

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

                                            (g) Assuming the authorization,

                  laws of general application relating to or affecting
                  creditors' rights generally (2) the application of general
                  principles of equity (regardless of whether such
                  enforceability is considered in a proceeding in equity or at
                  law); and (3) the unenforceability under certain circumstances
                  of provisions indemnifying a party against liability where
                  such indemnification is contrary to public policy;

                           In rendering such opinion, such counsel may rely as

                                    (vii) The Underwriter shall have received
         an opinion of Brobeck, Phleger & Harrison, tax counsel to the Company,
         dated the Closing Date and satisfactory in form and substance to you
         substantially to the effect that:

                                            (a) the Trust created by the Pooling
                  and Servicing Agreement will not be classified as an
                  association taxable as a corporation for federal income tax
                  purposes and, instead, under subpart E, part I of subchapter J
                  of the Internal Revenue Code of 1986, as amended, the Trust
                  will be treated as a grantor trust, and subject to possible
                  recharacterization of certain amounts paid by the Trust to the
                  Servicer, the holders of the Certificates will be treated as
                  owning an undivided pro-rata interest in the income and corpus
                  attributable to the Trust;

                                            (b) The statements in the Reg-
                  istration Statement and Prospectus under the headings
                  "Prospectus Summary -- Tax Status" and "Certain Tax
                  Consequences" to the extent that they constitute matters of
                  law or legal conclusions with respect thereto, have been
                  prepared or reviewed by such counsel and are correct in all
                  material respects; and

                                            (c) For California franchise tax
                  purposes, the Trust created by the Pooling and Servicing
                  Agreement will not be subject to California franchise or
                  income taxes, and Certificateholders who are not residents
                  of or otherwise subject to the tax in California will not be
                  subject to California franchise or income taxes with respect
                  to interest received from the Certificates or with respect to
                  any of the Contracts.

                                    (viii) The Underwriter shall have received

                  power to execute and deliver, and to take all action required

                  obtained, no authorization, consent, approval, license, formal
                  exemption or declaration from, nor any registration or filing
                  with, any court or governmental agency or body of the United
                  States of America or the State of New York, which if not
                  obtained would affect or impair the validity or enforceability

                  Indemnification Agreement against the Insurer, is required in

                  Indemnification Agreement or in connection with the Insurer's
                  performance of its obligations thereunder;

                                            (d) The Surety Bond, the Insurance
                  Agreement and the Indemnification Agreement have been duly
                  authorized, executed and delivered by the Insurer, and the
                  Surety Bond and, assuming due authorization, execution and
                  delivery of the Insurance Agreement by the parties thereto

                  enforceable in accordance with their respective terms subject,
                  as to enforcement, to (1) bankruptcy, reorganization,

                  subordination, presently or from time to time in effect and

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

                  qualification that the remedy of specific performance may be
                  subject to equitable defenses and to the discretion of the
                  court before which any proceedings with respect thereto may be
                  brought; and

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

                           In rendering such opinion, such counsel may rely as
         to matters of fact, to the extent deemed proper and as stated therein,
         on certificates of responsible officers of the Insurer and public
         officials. References to the Prospectus in this paragraph (viii)

                                    (ix) The Underwriter shall have received an
         opinion of counsel to the Trustee, dated the Closing Date and
         satisfactory in form and substance to you, substantially to the effect
         that:

                                            (a) The Trustee is a banking cor-
                  poration validly existing under the laws of the State of New
                  York;

                                            (b) The Trustee has the requisite
                  power and authority to execute, deliver and perform its
                  obligations under the Pooling and Servicing Agreement, and has
                  taken all necessary action to authorize the execution,
                  delivery and performance by it of the Pooling and Servicing
                  Agreement; and

                                            (c) The Pooling and Servicing
                  Agreement has been duly executed and delivered by the Trustee
                  and constitutes a legal, valid and binding obligation of the
                  Trustee, enforceable against the Trustee in accordance with
                  its terms, except that certain of such obligations may be
                  enforceable solely against the Trust Estate and except that
                  such enforcement may be limited by bankruptcy, insolvency,
                  reorganization, moratorium, liquidation, or other similar laws
                  applicable to banking corporations affecting the enforcement
                  of creditors' rights generally, and by general principles of

                  good faith and fair dealing (regardless of whether such
                  enforceability is considered in a proceeding in equity or at
                  law).

                                    (x) The Underwriter shall have received

         related matters as the Underwriter may require, and the Company shall
         have furnished to such counsel such documents as they reasonably

         Statement has been issued and no proceedings for that purpose have been
         instituted or are threatened by the Commission and that, subsequent to
         the date of the Prospectus, there has been no material adverse change
         in the financial position or results of operation of the Company's
         motor vehicle installment loan business except as set forth in or
         contemplated by the Prospectus or as described in such certificate.

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

         conditions on its part to be performed or satisfied thereunder at or
         prior to the Closing Date, that the representations and warranties of
         Onyx, as Servicer, in the Pooling and Servicing Agreement are true and
         correct as of the dates specified in the Pooling and Servicing

         position or results of operation of Onyx's motor vehicle installment
         loan business except as set forth in or contemplated by the Prospectus

         Certificate from a senior officer of the Insurer to the effect that

         thereof or supplement thereto as of its Effective Date or date of
         issuance, as the case may be, contained any untrue statement of a
         material fact or omitted to state any material fact required to be
         stated therein or necessary to make the statements

 

                                       26
<PAGE>   27
         therein, in light of the circumstances under which
         they were made, not misleading.

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

                  8.  Indemnification.

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

                                    (ii) The Underwriter severally agrees to
         indemnify and hold harmless the Company, its directors, each of its
         officers or agents who signed the Registration Statement, and each
         person, if any, who controls the Company within the meaning of Section
         15 of the Act against any and all loss, liability, claim, damage and
         expense described in the indemnity contained in subsection (i) of this
         Section 8, as in-

 

                                       27
<PAGE>   28
         curred, but only with respect to untrue statements or omissions, or
         alleged untrue statements or omissions, (A) made in the Registration
         Statement (or any amendment thereto) or any preliminary prospectus or
         the Prospectus (or any amendment or supplement thereto) in reliance
         upon and in conformity with written information furnished to the
         Company by the Underwriter through Merrill Lynch, Pierce, Fenner &
         Smith Incorporated expressly for use in the Registration Statement (or
         any amendment thereto) or such preliminary prospectus or the Prospectus
         (or any amendment or supplement thereto) or (B) made in the ABS Term
         Sheets distributed by the Underwriter and filed as a post-effective
         amendment to the Registration Statement or the Prospectus as a result
         of any filing pursuant to Section 5(x); provided however that the
         Underwriter will not be liable in any such case to the extent that any
         such loss, claim or damage or liability arises out of, or is based
         upon, an untrue statement or omission made in the ABS Term Sheet or any
         supplement thereto in reliance upon and in conformity with (x)
         information furnished to the Underwriter by the Company or (y)
         information contained in the Registration Statement or any preliminary
         prospectus or the Prospectus other than information described in clause
         (A) above.

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

 

                                       28
<PAGE>   29
         stances, be liable for the reasonable fees and expenses of more than
         one separate firm of attorneys, and, after notice from the indemnifying
         party to the indemnified party of its election so to assume the defense
         thereof, the indemnifying party shall not be liable to the indemnified
         party under subsections (i) or (ii) of this Section 8 for any legal
         expenses of other counsel or any other expenses, in each case
         subsequently incurred by the indemnified party, in connection with the
         defense thereof other than reasonable costs of investigation.

                  9. Contribution. In order to provide for just and equitable
contribution in circumstances in which the indemnity agreement provided for in
Section 8 is for any reason held to be unavailable other than in accordance with
its terms, then each indemnifying party shall contribute to the amount paid or
payable by such indemnifying party as a result of the losses, claims, damages or
liabilities referred to in 8(i) and 8(ii) above (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company on the one
hand and the Underwriter on the other from the offering of the Certificates or
(ii) if the allocation provided by clause (i) above is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault of
the Company on the one hand and of the Underwriter on the other in connection
with the statements or omissions which resulted in such losses, claims, damages
or liabilities as well as any other relevant equitable considerations. The
relative benefits received by the Company on the one hand and the Underwriter on
the other shall be deemed to be in the same proportion as the total net proceeds
from the offering (before deducting expenses) received by the Company bear to
the total underwriting discounts and commissions received by the Underwriter.
The relative fault shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company or by the Underwriter and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
untrue statement or omission. The amount paid by an indemnified party as a
result of the losses, claims, damages or liabilities referred to in the first
sentence of this Section 9 shall be deemed to include any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any action or claim which is the subject of this
Section 9. Notwith-

 

                                       29
<PAGE>   30
standing the provisions of this Section 9, the Underwriter shall not be required
to contribute any amount in excess of the underwriting discount or commission
applicable to the Certificates purchased by it hereunder. The Company and the
Underwriter agrees that it would not be just and equitable if contribution
pursuant to this Section 9 were determined by pro rata allocation or by any
other method of allocation which does not take account of the equitable
considerations referred to above in this Section 9. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.

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

                  11. Survival of Certain Representations and Obligations. The
respective indemnities, agreements, representations, warranties and other
statements of the Company or its officers and of the Underwriter set forth in or
made pursuant to this Agreement will remain in full force and effect, regardless
of any investigation, or statement as to the results thereof, made by or on
behalf of the Underwriter, the Company or any of their respective
representatives, officers or directors or any controlling person, and will
survive delivery of and payment for the Certificates. If for any reason the
purchase of the Certificates by the Underwriter is not consummated, the Company
shall remain responsible for the expenses to be paid or reim-

 

                                       30
<PAGE>   31
bursed by it pursuant to Section 6 and the respective obligations of the Company
and the Underwriter pursuant to Sections 6, 8 and 9 shall remain in effect. If
the purchase of the Certificates by the Underwriter is not consummated for any
reason other than solely because of the occurrence of any event specified in
clauses (b), (c) or (d) of Section 7(iii), the Company will reimburse the
Underwriter for all out-of-pocket expenses (including fees and disbursements of
counsel) reasonably incurred by it in connection with the offering of the
Certificates.

                  12. Notices. All communications hereunder will be in writing
and, if sent to the Underwriter, will be mailed, delivered or telegraphed and
confirmed to the Underwriter at c/o Merrill Lynch & Co., World Financial Center,

5th Floor, Irvine CA 92718, Attention: Regan E. Kelly, Esq., Executive Vice

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

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

CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

                  16. Severability of Provisions. Any covenant, provisions,
agreement or term of this Agreement that is prohibited or is held to be void or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof.

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

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

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

of any Distribution Date shall be determined by discounting, on a monthly basis,
each such scheduled payment of Monthly P&I from the Due Date for such payment
back to the Due Date for such Contract in the Collection Period related to such
Distribution Date, using the applicable discount rate specified below. Such
present value as of the Cut-Off Date or the Subsequent Transfer Date, as
applicable, shall be determined by discounting, on a monthly basis, each such
scheduled payment of Monthly P&I from the Due Date for such payment back to the
Cut-Off Date or Subsequent Transfer Date, using the applicable discount rate

Liquidated Contract or a Repurchased Contract is reduced to zero as of the close
of business on the Due Date for such Contract in the Collection Period in which
such Contract became a Liquidated Contract or a Repurchased Contract. The
principal balance of a Simple Interest Contract that becomes a Liquidated
Contract or a Repurchased Contract is reduced to zero as of the close of
business on the date the Contract becomes a Liquidated Contract or is
repurchased, as the case may be. As used herein, reference to the Scheduled

of such Contract as of close of business on the last day of the Collection

owned by the Servicer or otherwise.

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

                  (ii) the Contract Documents relating to the Subsequent
         Contracts;

                  (iii) the right of the Seller, as purchaser under the Purchase

         It is the intention of the Seller and the Trustee that the assignment
and transfer herein contemplated constitute (and shall be construed for all
purposes as) a sale of the Trust Estate (other than the Surety Bond and the
Pre-Funded Amount), conveying good title thereto free and clear of any liens and
encumbrances, from the Seller to the Trust. However, in the event that such
conveyance is deemed to be a pledge to secure a loan (in spite of the express
intent of the parties hereto that this conveyance is to be treated as a true and
complete sale), the Seller hereby


                                       19
<PAGE>   24
grants to the Trustee on behalf of the Trust for the benefit of the
Certificateholders a first priority perfected security interest in all of the
Seller's right, title and interest in the Trust Estate whether now existing or
hereafter created (other than the Surety Bond and the Pre-Funded Amount), and
all proceeds of the foregoing to secure the loan deemed to be made in connection
with such pledge and, in such event, this Agreement shall constitute a security
agreement under applicable law.

         (c) The sale and assignment of the Subsequent Contracts and the other
property and rights related thereto described in Section 2.1(b) shall be subject
to the satisfaction of each of the following conditions as of the related
Subsequent Transfer Date, as applicable:

                  (i) the Seller shall have delivered to the Trustee the
         Subsequent Contracts together with a duly executed Transfer
         Certificate, substantially in the form of Exhibit E-1;

                  (ii) neither the Servicer nor the Seller was insolvent nor
         will either of them have been made insolvent by such transfer nor is
         either of them aware of any pending Seller or Servicer insolvency;

                  (iii) the addition of such Subsequent Contracts will not cause
         as of the related Subsequent Closing Date and has not caused as of the
         related Subsequent Transfer Date the tax consequences to the Trust or
         the Certificateholders to be other than as discussed in the prospectus
         for the Trust under the caption "Certain Tax Consequences" and in the
         tax opinion of counsel to the Seller delivered on the Closing Date, as
         confirmed in the legal opinion delivered on the immediately following
         Subsequent Closing Date dated the date of such Subsequent Closing Date
         pursuant to Section 2.1(h)(iv);

                  (iv) the Funding Period shall not have terminated;

                  (v) no selection procedures believed by the Seller or the
         Servicer to be adverse to the interests of the Certificateholders shall
         have been utilized in selecting the Subsequent Contracts;

                  (vi) the Seller and the Trustee shall not have been advised by
         either Rating Agency on or before the Business Day immediately
         preceding such Subsequent Transfer Date that the conveyance of the
         Subsequent Contracts would result in a qualification, modification or
         withdrawal of its then-current rating of the Certificates;

                  (vii) the weighted average APR of the Contracts (including the
         Subsequent Contracts) is not less than _____%; and

                  (viii) the weighted average remaining term of the Contracts
         (including the Subsequent Contracts) as of the Subsequent Transfer Date
         will not be greater than 72 months.


                                       20
<PAGE>   25
         (d) In connection with the sale of the Contracts pursuant to the
Purchase Agreement, Onyx has filed with the office of the Secretary of State of
the State of California UCC-1 financing statements naming Onyx as seller and
including the Initial Contracts and Subsequent Contracts in the description of
the assets being sold thereunder. In connection with the sale of the Initial
Contracts pursuant to this Agreement, the Seller has filed or caused to be filed
UCC-1 financing statements, executed by the Seller as seller, naming the Trust
as purchaser and describing the Contracts as the assets being sold by it to the
Trust, with the Office of the Secretary of State of the State of California. The
Seller shall have caused UCC-2 termination statements to have been filed with
the Office of Secretary of State of the State of California terminating any
outstanding security interests in the Initial Contracts. The Seller will deliver
the Subsequent Contracts to the Trustee on each Subsequent Transfer Date
together with the Transfer Certificate relating to such Subsequent Contracts. On
each Subsequent Closing Date, the Seller shall cause UCC-1 financing statements
to be filed with the California Secretary of State executed by the Seller as
seller and the Trustee, on behalf of the Trust, as purchaser and describing the
Subsequent Contracts delivered to the Trustee from and including the preceding
Subsequent Closing Date (or the Closing Date with respect to the first
Subsequent Closing Date) as the assets sold and shall have caused UCC-2
termination statements to have been filed with the office of the Secretary of
State of the State of California terminating any outstanding security interests
in such Subsequent Contracts and certificates from each secured creditor of the
Seller confirming that such creditor has no claim of a security interest in any
of such Subsequent Contracts. From time to time, the Servicer shall cause to be
taken such actions as are necessary to continue the perfection of the Trust's
ownership interest in the Contracts and to continue the first priority security
interest of the Trust in the Financed Vehicles and their proceeds (other than,
as to such priority, any statutory lien arising by operation of law after the
Closing Date or the Subsequent Transfer Date, as applicable, which is prior to
such interest), including, without limitation, the filing of financing
statements, amendments thereto or continuation statements and the making of
notations on records or documents of title.

         (e) If any change in the name, identity or corporate structure of Onyx,
the Seller or the relocation of the chief executive office of any of them would
make any financing or continuation statement or notice of lien filed under this
Agreement misleading within the meaning of applicable provisions of the UCC or
any title statute, the Servicer, within the time period required by applicable
law, shall file such financing statements or amendments as may be required to
preserve and protect the interests of the Trustee on behalf of the Trust and the
Certificateholders in the Contracts and in the related Financed Vehicles and
proceeds thereof. Promptly thereafter, and in any event within 30 days of such
change or relocation, the Servicer shall deliver to the Trustee an Opinion of
Counsel stating that, in the opinion of such counsel, all financing statements
or amendments necessary fully to preserve and protect the interests of the
Trustee and the Certificateholders in the Contracts and in the related Financed
Vehicles and proceeds thereof have been filed, and reciting the details of such
filings.

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

         (g) The Servicer shall pay all reasonable costs and disbursements in
connection with the perfection and the maintenance of perfection, as against all
Persons other than the Trustee, 


                                       21
<PAGE>   26
of the Trust's right, title and interest in and to the Contracts and in
connection with maintaining the first priority security interest in the related
Financed Vehicles and the proceeds of such Financed Vehicles.

         (h) On each Subsequent Closing Date, the Seller shall:

                  (i) file a UCC-1 financing statement with the Secretary of
         State of the State of California executed by the Seller as seller,
         naming the Trustee, on behalf of the Trust, as purchaser and describing
         the Subsequent Contracts delivered to the Trustee on or after the
         preceding Subsequent Closing Date (or the Closing Date, in the case of
         the first Subsequent Closing Date) as the assets sold by it to the
         Trust;

                  (ii) cause to be filed a UCC-2 termination statement with the
         office of the Secretary of State of the State of California terminating
         any outstanding security interests in the Subsequent Contracts subject
         to the UCC-1 financing statement described in clause (i), above and
         deliver a certificate from each secured creditor of the Seller
         confirming that such creditor has no claim of any security interest in
         any of such Subsequent Contracts;

                  (iii) deliver to each Rating Agency, the Insurer and the
         Trustee a Subsequent Closing Date Certificate; and

                  (iv) deliver to each Rating Agency, the Insurer and the
         Trustee an Opinion of Counsel with respect to the absence of negative
         tax consequences to the Trust, the characterization of the transfer of
         the Subsequent Contracts and the perfection of the Trustee's interest
         on behalf of the Trust therein.

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

         SECTION 2.2. Representations and Warranties. The Seller represents and
warrants to the Trustee and the Trust for the benefit of the Certificateholders
and the Insurer as follows:

         (a) As to the Seller, as of the Closing Date with respect to the

         corporation in good standing, and shall have obtained all necessary
         licenses and approvals in all jurisdictions in which the ownership or

         qualifications;

                  (iii) the Seller has the power and authority to execute and
         deliver this Agreement and to carry out its terms; the Seller has full
         power and authority to sell and assign the property to be sold and

         part of the Trust and has duly authorized such sale and assignment to
         the Trustee on behalf of the Trust by all necessary corporate action;
         and the execution, delivery, and performance of this Agreement has been
         duly authorized by the Seller by all necessary corporate action;

                  (iv) this Agreement constitutes (A) a valid sale, transfer,
         and assignment of the Contracts, enforceable against creditors of and
         purchasers from the Seller and (B) a legal, valid, and binding
         obligation of the Seller enforceable in accordance with its terms,
         except as such enforceability may be limited by bankruptcy, insolvency,
         reorganization, or other similar laws affecting the enforcement of
         creditors' rights in general and by general principles of equity,
         regardless of whether such enforceability shall be considered in a
         proceeding in equity or at law;

                  (v) the consummation of the transactions contemplated by this
         Agreement and the fulfillment of the terms hereof shall not conflict
         with, result in any breach of any of the terms and provisions of, nor
         constitute (with or without notice or lapse of time) a default under,
         the Certificate of Incorporation or Bylaws of the Seller, or any
         indenture, agreement, or other instrument to which the Seller is a
         party or by which it shall be bound; nor result in the creation or
         imposition of any Lien upon any of the properties of the Seller
         pursuant to the terms of any such indenture, agreement, or other
         instrument (other than this Agreement); nor violate any law or any
         order, rule, or regulation applicable to the Seller of any court or of
         any federal or state regulatory body, administrative agency, or other

         properties; and

                  (vi) to the Seller's best knowledge after due inquiry, there

         the Seller which might adversely affect the federal income tax
         attributes of the Certificates.

         (b) As to each Initial Contract (except as noted below as being
applicable only to either Rule of 78's Contracts or Simple Interest Contracts):


                                       23
<PAGE>   28
                  (i) the information pertaining to such Initial Contract set
         forth in the related Schedule of Contracts was true and correct in all
         material respects at the Closing Date and the calculations of the
         Scheduled Balances appearing in such Schedule of Contracts for each
         such Initial Contract at the Cut-Off Date, and in the case of Rule of
         78's Contracts at each Distribution Date thereafter prior to the
         related Maturity Date, have been performed in accordance with this
         Agreement and are accurate;

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

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

                  (iv) as of the Closing Date, the Seller had good and
         marketable title to and was the sole owner of each Initial Contract to
         be transferred to the Trust pursuant to Section 2.1 free of liens,
         claims, encumbrances and rights of others and, upon transfer of such
         Contract to the Trustee pursuant to Section 2.1, the Trust will have
         good and marketable title to, will have a first priority perfected
         security interest in and will be the sole owner of such Contract free
         of liens, encumbrances and rights of others;

                  (v) as of the Cut-Off Date, the most recent scheduled payment
         on each such Initial Contract had been made or was not delinquent more
         than 30 days and, to the best


                                       24
<PAGE>   29
         of the Seller's knowledge, all payments on the Initial Contract were
         made by the related Obligor;

                  (vi) as of the Closing Date, there is no lien against the
         related Initial Financed Vehicle for delinquent taxes;

                  (vii) as of the Closing Date, there is no right of rescission,
         offset, defense or counterclaim to the obligation of the Obligors to
         pay the unpaid principal or interest due under such Initial Contract;
         the operation of the terms of such Initial Contract or the exercise of
         any right thereunder will not render such Initial Contract
         unenforceable in whole or in part or subject such Initial Contract to
         any right of rescission, offset, defense or counterclaim, and the
         Seller has no knowledge that such right of rescission, offset, defense
         or counterclaim has been asserted or threatened;

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

                  (ix) such Initial Contract, and the sale of the Initial
         Financed Vehicle sold thereunder, complied, at the time it was made, in
         all material respects with all applicable federal, state and local laws
         (and regulations thereunder), including without limitation usury, equal
         credit opportunity, fair credit reporting, truth-in-lending or other
         similar laws, the Federal Trade Commission Act, and applicable state
         laws regulating retail installment sales contracts and loans in general
         and motor vehicle retail installment contracts and loans in particular;
         and the consummation of the transactions herein contemplated,
         including, without limitation, the transfer of ownership of the Initial
         Contracts to the Trustee and the receipt of interest by the
         Certificateholders, will not violate any applicable federal, state or
         local law;

                  (x) such Initial Contract is the legal, valid and binding
         obligation of the Obligor thereunder and is enforceable in accordance
         with its terms, except only as such enforcement may be limited by
         bankruptcy, insolvency or similar laws affecting the enforcement of
         creditors' rights generally; each party to such Initial Contract had
         full legal capacity to execute and deliver such Initial Contract and
         all other documents related thereto and to grant the security interest
         purported to be granted thereby; the terms of such Initial Contract
         have not been waived, amended or modified in any respect, except by
         instruments that are part of the Contract Documents, and no such
         waiver, amendment or modification has caused such Initial Contract to
         fail to meet all of the representations, warranties and conditions, set
         forth herein with respect thereto;

                  (xi) such Initial Contract contains customary and enforceable
         provisions such as to render the rights and remedies of the holder or
         assignee thereof adequate for the practical realization against the
         collateral of the benefits of the security, subject, as to
         enforceability, to bankruptcy, insolvency, reorganization or similar
         laws affecting the enforcement of creditors' rights generally;

                  (xii) as of the Closing Date, there was no default, breach,
         violation or event permitting acceleration existing under such Initial
         Contract (except payment delinquencies permitted by subparagraph (v)
         above) and no event which, with notice and the expiration of any grace
         or cure period, would constitute such a default, breach, violation or
         event permitting acceleration under such Initial Contract, and the
         Seller has not waived any such default, breach, violation or event
         permitting acceleration except payment delinquencies permitted by
         subparagraph (v) above;

         Financed Vehicle will require that the related Obligor obtain and
         maintain in effect for the Initial Financed Vehicle a comprehensive and
         collision insurance policy (i) in an amount at least equal to the
         lesser of (x) its maximum insurable value or (y) the principal amount
         due from the Obligor under the related Initial Contract, (ii) naming
         Onyx as a loss payee and (iii) insuring against loss and damage due to
         fire, theft, transportation, collision and other risks generally
         covered by comprehensive and collision coverage and (b) the Servicer
         shall have put in place a vendor's single interest insurance policy
         providing coverage upon repossession of an Initial Financed Vehicle in
         an amount equal to the lesser of the actual cash value of such Initial
         Financed Vehicle, the cost of repair or replacement for such Initial
         Financed Vehicle and the unpaid balance of the related Contract. Each
         of Onyx and the Seller shall at all times comply with all of the
         provisions of such insurance policies applicable to it;

                  (xv) such Initial Contract was either originated by Onyx or
         acquired by Onyx from a Dealer with which it ordinarily does business,

         fully amortize the principal balance of such Initial Contract by its
         Maturity Date;

                  (xvii) there is only one original of such Initial Contract and
         such original, together with all other Contract Documents, is being
         held by the Trustee; provided, however, that upon the execution by the
         Trustee and the Servicer of a letter agreement revocably appointing the
         Servicer as agent of the Trustee to act as custodian of the Contract
         Documents in accordance with Section 2.4, such original Initial
         Contracts together with all other Contract Documents may be held by the
         Servicer. Each original Initial Contract has been segregated to show
         the Trust as owner thereof, unless the Insurer has waived the
         requirement for such segregation by notice in writing to the Trustee
         and the Servicer;

                  (xxi) as of the Cut-Off Date, the Seller has not received

         bankruptcy;

                  (xxii) the Obligor of such Initial Contract was located in

         the Outstanding Principal Balance of all Initial Contracts is
         attributable to used Financed Vehicles.

         (d) As to each Subsequent Contract as of the Subsequent Transfer Date
on which such Subsequent Contract is delivered to the Trustee:

                  (i) the information pertaining to such Subsequent Contract set
         forth in the related Transfer Certificate was true and correct in all
         material respects;

                  (ii) immediately prior to its sale and assignment to the

                                       27
<PAGE>   32
         of Onyx in the related Subsequent Financed Vehicle, and such security
         interest has been duly perfected and is prior to all other liens upon
         and security interests in such Subsequent Financed Vehicle which now
         exist or may hereafter arise or be created (except, as to priority, for
         any lien for unpaid taxes or unpaid storage or repair charges which may
         arise after the Subsequent Transfer Date); such security interest had
         been assigned by Onyx to the Seller pursuant to the Purchase Agreement
         and, as of the Subsequent Transfer Date, has been assigned by the
         Seller to the Trust pursuant to Section 2.1(b)(i) hereof;

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

                  (iv) immediately prior to the related Subsequent Transfer
         Date, the Seller had good and marketable title to and was the sole
         owner of such Subsequent Contract to be transferred to the Trust
         pursuant to Section 2.1 free of liens, claims, encumbrances and rights
         of others and, upon delivery of such Subsequent Contract to the
         Trustee, the Trust will have good and marketable title to, will have a
         first perfected security interest in and will be the sole owner of such
         Subsequent Contract free of liens, encumbrances and rights of others;

                  (v) the most recent scheduled payment on each such Subsequent
         Contract has been made or is not delinquent more than 30 days and, to
         the best of the Seller's knowledge, all payments on the Subsequent
         Contract have been made by the related Obligor;

                  (vi) there is no lien against the related Subsequent Financed
         Vehicle for delinquent taxes;


                                       28
<PAGE>   33
                  (vii) there is no right of rescission, offset, defense or
         counterclaim to the obligation of the Obligor to pay the unpaid
         principal or interest due under such Subsequent Contract; the operation
         of the terms of the related Subsequent Contract or the exercise of any
         right thereunder will not render such Subsequent Contract unenforceable
         in whole or in part or subject such Subsequent Contract to any right of
         rescission, offset, defense or counterclaim, and the Seller has no
         knowledge that such right of rescission, offset, defense or
         counterclaim has been asserted or threatened;

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

                  (ix) such Subsequent Contract, and the sale of the Subsequent
         Financed Vehicle sold thereunder, complied, at the time it was made, in
         all material respects with all applicable federal, state and local laws
         (and regulations thereunder), including without limitation usury, equal
         credit opportunity, fair credit reporting, truth-in-lending or other
         similar laws, the Federal Trade Commission Act, and applicable state
         laws regulating retail installment sales contracts and loans in general
         and motor vehicle retail installment contracts and loans in particular;
         and the consummation of the transactions herein contemplated,
         including, without limitation, the transfer of ownership of such
         Subsequent Contract to the Trustee and the receipt of interest by the
         Certificateholders, will not violate any applicable federal, state or
         local law;

                  (x) such Subsequent Contract is the legal, valid and binding
         obligation of the Obligor thereunder and is enforceable in accordance
         with its terms, except only as such enforcement may be limited by
         bankruptcy, insolvency or similar laws affecting the enforcement of
         creditors' rights generally; each party to such Subsequent Contract had
         full legal capacity to execute and deliver such Subsequent Contract and
         all other documents related thereto and to grant the security interest
         purported to be granted thereby; the terms of such Subsequent Contract
         have not been waived, amended or modified in any respect, except by
         instruments that are part of the Contract Documents with respect to the
         Subsequent Contracts, and no such waiver, amendment or modification has
         caused such Subsequent Contract to fail to meet all of the
         representations, warranties and conditions set forth herein with
         respect thereto;

                  (xi) such Subsequent Contract contains customary and
         enforceable provisions so as to render the rights and remedies of the
         holder or assignee thereof adequate for the practical realization
         against the collateral of the benefits of the security, subject, as to
         enforceability, to bankruptcy, insolvency, reorganization or similar
         laws affecting the enforcement of creditors' rights generally;

                  (xii) there is no default, breach, violation or event
         permitting acceleration existing under such Subsequent Contract (except
         payment delinquencies permitted by subparagraph (v) above) and no event
         which, with notice and the expiration of any grace or cure period,
         would constitute such a default, breach, violation or event permitting


                                       29
<PAGE>   34

         acceleration under such Subsequent Contract, and the Seller has not
         waived any such default, breach, violation or event permitting
         acceleration except payment delinquencies permitted by subparagraph (v)
         above;

                  (xiii) such related Subsequent Financed Vehicle is covered by
         the Blanket Insurance Policy; each of Onyx and the Seller shall at all
         times comply with all of the provisions of such insurance policies
         applicable to it;

                  (xiv) (a) such Subsequent Contract requires the Obligor to
         obtain and maintain a comprehensive and collision insurance policy with
         respect to the related Subsequent Financed Vehicle (i) in an amount at
         least equal to the lesser of (y) its maximum insurable value or (z) the
         principal amount due from the Obligor under the related Subsequent
         Contract, (ii) naming Onyx as a loss payee and (iii) insuring against
         loss and damage due to fire, theft, transportation, collision and other
         risks generally covered by comprehensive and collision coverage and (b)
         the Servicer maintains a vendor's single interest insurance policy
         providing coverage upon repossession of a Subsequent Financed Vehicle
         in an amount equal to the lesser of the actual cash value of such
         Subsequent Financed Vehicle, the cost of repair or replacement for such
         Subsequent Financed Vehicle and the unpaid balance of the related
         Contract. Each of Onyx and the Seller shall at all times comply with
         all of the provisions of such insurance policies applicable to it;

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

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

                  (xvii) there is only one original of such Subsequent Contract
         and such original, together with all other Contract Documents with
         respect to the Subsequent Contracts, upon delivery to the Trustee on
         the related Subsequent Transfer Date is being held by the Trustee;
         provided, however, that upon the execution by the Trustee and the

         agent of the Trustee to act as custodian of the Contract Documents in
         accordance with Section 2.4, such original Initial Contracts together
         with all other Contract Documents may be held by the Servicer. Each
         original Initial Contract has been segregated to show the Trust as
         owner thereof, unless the Insurer has waived the requirement for such
         segregation by notice in writing to the Trustee and the Servicer;

         Financed Vehicle;

                  (xxi) as of the Cut-Off Date, the Seller has not received

construed as, and the Seller is specifically not making, any representations and

performance of the Contracts.

         (f) The Seller has not prepared any financial statement which accounts
for the transfer of the Trust Estate (other than the Surety Bond [and the
Pre-Funded Amount]) hereunder to the Trust in any manner other than a sale of
the Trust Estate (other than the Surety Bond) by it to the Trust, and the Seller
has not in any other respect (including, but not limited to, for accounting and
tax reporting purposes) accounted for or treated the transfer of the Trust
Estate (other than the Surety Bond [and the Pre-Funded Amount]) hereunder in any
manner other than as a sale and absolute assignment to the Trust of the Seller's
full right, title and ownership interest in the Trust Estate (other than the
Surety Bond [and the Pre-Funded Amount]) to the Trust.

         SECTION 2.3. Repurchase of Certain Contracts. The representations and
warranties of the Seller set forth in Section 2.2 with respect to each Contract
and each of the conditions set forth in Section 2.1(c) and Section 2.1(h) with
respect to each transfer of Subsequent Contracts shall survive delivery of the
Contract Documents to the Trustee and shall continue until the termination of
this Agreement. Upon discovery by the Seller, the Servicer, the Insurer or a
Responsible Officer of the Trustee that any of such representations or
warranties was incorrect 


                                       31
<PAGE>   36
as of the time made or that any of the Contract Documents relating to any such
Contract has not been properly executed by the Obligor or contains a material
defect or has not been received by the Trustee (or the Servicer in its capacity
as custodian of the Trustee), such Person making such discovery shall give
prompt notice to the other such Persons. If any such defect, incorrectness or
omission materially and adversely affects the interest of the
Certificateholders, the Trustee or the Insurer, the Seller shall cure the defect
or eliminate or otherwise cure the circumstances or condition in respect of
which such representation or warranty was incorrect as of the time made;
provided that if the Seller is unable to do so by the last day of the Collection
Period following the Collection Period (or, if the Seller elects, the last day
of such Collection Period) during which the Seller becomes aware of or receives
written notice from the Trustee, the Insurer or the Servicer of such defect,
incorrectness or omission, it shall repurchase such Contract on the last day of
such Collection Period from the Trust at the Repurchase Amount in the manner set
forth in Section 4.4. Upon any such repurchase, the Trustee on behalf of the
Trust shall execute and deliver such instruments of transfer or assignment, in
each case without recourse, as shall be necessary to vest in the Seller any
Contract purchased hereunder. The sole remedy of the Trustee, the Trust, or the
Certificateholders with respect to a breach of the Seller's representations and
warranties pursuant to Section 2.2 or non-compliance with Section 2.1(c) or
Section 2.1(h) shall be to require the Seller to repurchase Contracts pursuant
to this Section provided, however, that the Seller shall indemnify the Trustee,
its officers, directors, agents and employees, the Insurer, the Trust and the
Certificateholders against all costs, expenses, losses, damages, claims and
liabilities, including reasonable fees and expenses of counsel, which may be
asserted against or incurred by any of them as a result of third-party claims
arising out of the events or facts giving rise to such breach.

         SECTION 2.4. Duties and Appointment of Custodian.

         (a) Duties of Custodian. The Trustee, and any Custodian appointed
pursuant to Section 2.4(b), while acting as Custodian shall:

                  (i) segregate and maintain continuous custody of the Contract
         Documents in secure and fireproof facilities in accordance with
         customary standards for such custody;

                  (ii) with respect to the Contract Documents, (A) act
         exclusively as the Custodian for the benefit of the Certificateholders
         and for the Insurer and (B) hold all Contract Documents for the
         exclusive use (notwithstanding Sections 2.4(a)(iii) and 2.4(a)(iv)
         below) and for the benefit of the Certificateholders and the Insurer;

                  (iii) to the extent the Servicer directs the Custodian in
         writing, the Custodian shall deliver certain specified Contract
         Documents to the Servicer to enable the Servicer to service the
         Contracts pursuant to the Agreement. At such time as the Servicer
         returns such Contract Documents to the Custodian, the Servicer shall
         provide written notice of such return to the Custodian. The Custodian
         shall acknowledge receipt of the returned materials by signing the
         Servicer's notice and shall promptly send copies of such acknowledgment
         or receipt to the Servicer;


                                       32
<PAGE>   37
                  (iv) upon reasonable prior written notice, permit the Servicer
         and the Insurer to examine the Contract Documents in the possession, or
         under the control, of the Custodian; and

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

         (b) Appointment of Custodian. As of the Closing Date, the Trustee shall
be the Custodian of the Contract Files; provided, however, that upon the
execution by the Trustee of a letter agreement with the consent of the Insurer
(such consent not to be unreasonably withheld) substantially in the form of
Exhibit A attached hereto (the "Appointment of Custodian"), revocably appointing
the Servicer or such other entity acceptable to the Insurer as agent of the
Trustee to act as Custodian (the "Successor Custodian") of the Contract
Documents, such Successor Custodian shall be so appointed and shall from the
effective date of such Appointment of Custodian retain custody of the Contract
Documents and any and all other documents relating to a Contract or the related
Obligor or Financed Vehicle. As of the effective date of such Appointment of
Custodian, the Contract Documents and any and all other documents relating to a
Contract or the related Obligor or Financed Vehicle will be delivered to the
Successor Custodian in its capacity as agent of the Trustee acting as Custodian.

         If the Servicer is appointed Successor Custodian as of the date
specified in the Appointment of Custodian, the Servicer shall maintain the
Contract Documents held by it in a file area physically separate from the other
installment sales contracts owned or serviced by it or any of its Affiliates,
which area shall be clearly marked to indicate the Trust as the owner of, and
the Insurer as the holder of the security interest in, the Contract Documents;
except that if the Insurer has waived the requirement for such segregation by
notice in writing to the Trustee and the Servicer, such file area may contain
contract documents for other installment sales contracts serviced by the
Servicer.

         SECTION 2.5.       Duties of Servicer Relating to the Contracts.

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


                                       33
<PAGE>   38
and maintain its accounting, records, and computer systems as herein provided;
and (iv) promptly take appropriate action to remedy any such failure.

         (b) Maintenance of and Access to Records. The Servicer shall maintain
each Contract File (other than the Contract Documents, unless the Servicer is
acting as Custodian) at the address of the Servicer set forth in Section 11.5,
or at such other location as shall be specified to the Trustee and the Insurer
by 30 days' prior written notice. The Servicer shall permit the Trustee or the
Insurer or their duly authorized representatives, attorneys, or auditors to
inspect the Contract Files and the related accounts, records, and computer
systems maintained by the Servicer at such times as the Trustee or the Insurer
may request.

         (c) Release of Documents. If the Servicer is acting as Custodian
pursuant to Section 2.4, upon instruction from the Trustee (a copy of which
shall be furnished to the Insurer), the Servicer shall release any document in
the Contract Files to the Trustee, the Trustee's agent, or the Trustee's
designee, as the case may be, at such place or places as the Trustee may
designate, as soon as practicable.

         (d) Monthly Reports. On the Servicer Report Date of each month,
commencing with the month of the Closing Date, the Servicer shall deliver to the
Trustee and Insurer, a certificate of a Servicing Officer stating (i) the
Contract Number and outstanding principal balance of each Contract that has
become a Liquidated Contract since the Business Day immediately preceding the
date of the last certificate delivered pursuant to this Section 2.5(d) (or since
the Closing Date in the case of the first such certificate); (ii) that all
proceeds received in respect of such Contract have been deposited in or credited
to the Collection Account or Payahead Account as required by Section 4.2; (iii)
that, if such Contract has been the subject of a Full Prepayment pursuant to
clause (a) of the definition of the term "Full Prepayment" or is a Liquidated
Contract pursuant to clause (iii) of the definition of the term "Liquidated
Contract," all proceeds received in respect thereof have been deposited in or
credited to the Collection Account or Payahead Account in accordance with
Section 4.2; (iv) that, if such Contract has been the subject of a Full
Prepayment pursuant to clause (b) of the definition of the term "Full
Prepayment," the correct Repurchase Amount has been deposited in or credited to
the Collection Account in accordance with Sections 2.3 or 3.7; (v) that, if such
Contract is a Liquidated Contract pursuant to clause (ii) of the definition of
the term "Liquidated Contract," there have been deposited in or credited to the
Collection Account or Payahead Account the related Net Liquidation Proceeds in
accordance with Section 4.2; and (vi) that the Trustee is authorized to release
such Contract and the related Contract Documents as provided herein.

         (e) Schedule of Title Documents. The Servicer shall deliver to the
Trustee and the Insurer (i) within 60 days of the Closing Date, a schedule of
Title Documents which as of the Closing Date did not show the Servicer as first
lienholder and (ii) within 180 days of the Closing Date as to the Initial
Contracts and as of the related Subsequent Transfer Date with respect to the
Subsequent Contracts, a schedule of Title Documents which as of the date prior
to such delivery do not show the Servicer as first lienholder and as to which
the Seller is obligated to repurchase pursuant to the provisions hereof.


                                       34
<PAGE>   39
         (f) Electronic Marking of Contracts; Possession. The Servicer shall
cause the electronic record of the Contracts maintained by it to be clearly
marked to indicate that the Contracts have been sold to the Trust and shall not
in any way assert or claim an ownership interest in the Contracts. It is
intended that by the Servicer's and the Seller's agreement pursuant to Section
2.4, Section 2.5 hereof and the Appointment of Custodian, the Trustee on behalf
of the Trust shall be deemed to have possession of the Contract Documents for
purposes of Section 9-305 of the UCC of the State in which the Contract
Documents are located.

         SECTION 2.6. Instructions; Authority to Act. The Servicer shall be
deemed to have received proper instructions (a copy of which shall be furnished
to the Insurer) with respect to the Contract Files upon its receipt of written
instructions signed by a Responsible Officer of the Trustee.

         SECTION 2.7. Indemnification. The Servicer, as custodian, shall
indemnify the Trustee and its officers, directors, agents and employees, the
Insurer, the Trust and the Certificateholders for any and all liabilities,
obligations, losses, compensatory damages, payments, costs, or expenses of any
kind whatsoever (including the reasonable fees and expenses of counsel) that may
be imposed on, incurred, or asserted against the Trustee, the Insurer, the Trust
and the Certificateholders as the result of any act or omission in any way
relating to the maintenance and custody by the Servicer of the Contract Files,
or the failure of the Servicer to perform its duties and service the Contracts
in compliance with the terms of this Agreement; provided, however, that the
Servicer shall not be liable for any portion of any such amount resulting from
the willful misfeasance, bad faith, or gross negligence of the Trustee. The
Servicer shall also indemnify and hold harmless the Trust, the Trust Estate, the
Trustee and the Certificateholders against any taxes that may be asserted at any
time against any of them with respect to the Contracts, including any sales,
gross receipts, general corporation, personal property, privilege or license
taxes (but exclusive of federal or other income taxes arising out of payments on
the Contracts) and the costs and expenses in defending against such taxes. The
Servicer shall immediately notify the Trustee if a claim is made by a third
party with respect to the Contracts, shall assume, with the consent of the
Trustee, the defense of any such claim and shall pay all expenses in connection
therewith, including counsel fees, and shall promptly pay, discharge and satisfy
any judgment or decree which may be entered against it, the Trustee or the Trust
with respect to the Contracts.

         SECTION 2.8. Effective Period and Termination. The Trustee's
appointment as Custodian shall become effective as of the Closing Date and shall
continue in full force and effect until the earlier of (i) the execution of the
Appointment of Custodian, (ii) the removal of the Trustee pursuant to Section
9.10 or (iii) the Final Distribution Date. Following the execution of the
Appointment of Custodian, the Successor Custodian's appointment as Custodian
shall continue in full force and effect until terminated under this Section 2.8
or until the Final Distribution Date, whichever occurs first. If Onyx shall
resign as Servicer under Section 7.4 or if all of the rights and obligations of
the Servicer shall have been terminated under Section 8.1, the appointment of
the Servicer as Custodian may be terminated by the Trustee, the Insurer,
or by the Holders of Certificates evidencing in the aggregate at least 25% of 
the Pool/Pre-Funding Balance, in the same manner as the Trustee, the
Insurer, or such Holders may terminate the rights and obligations of the
Servicer under Section 8.1 (but no occurrence of an


                                       35
<PAGE>   40
Event of Default shall be a precondition to termination). As soon as practicable
after any termination of such appointment, the Custodian shall, at its own
expense, deliver or cause the delivery of the Contract Files to the Trustee or
the Trustee's agent at such place or places as the Trustee may reasonably
designate and shall cooperate in good faith to effect such delivery. The
foregoing notwithstanding, if the Servicer is acting as Custodian, the Servicer
shall, at the request of the Insurer, redeliver the Contract Documents to the
Trustee in the event that such redelivery is required by any Rating Agency to
consider the Certificates investment grade without consideration of the Surety
Bond.

         SECTION 2.9.       Nonpetition Covenant.

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

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

         SECTION 2.10. Collecting Title Documents Not Delivered at the Closing
Date or Subsequent Closing Date. In the case of any Initial Contract or
Subsequent Contract in respect of which, in place of a Title Document, the
Trustee received on the Closing Date or Subsequent Closing Date, as applicable,
written evidence from the Dealer selling the related Initial Financed Vehicle or
Subsequent Financed Vehicle, as applicable, or Onyx that the Title Document for
such Financed Vehicle showing Onyx as first lienholder has been applied for from
the Registrar of Titles, the Servicer shall use its best efforts to collect (or,
in the case of the State of California, to obtain evidence in the electronic
title records of) such Title Document from the Registrar of Titles as promptly
as possible. If such Title Document showing the Servicer as first lienholder is
not received (or, in the case of the State of California, verified in the
electronic title records) by the Servicer within 180 days after the Closing Date
with respect to the Initial Contracts or after each Subsequent Closing Date with
respect to the Subsequent Contracts covered thereby, as applicable, then the
representation and warranty in Section 2.2(b)(iii) as to such Initial Contracts
and in Section 2.2(d)(iii) as to such Subsequent Contracts, as applicable, in
respect of such Contract shall be deemed to have been incorrect in a manner that
materially and adversely affects the Certificateholders and the Seller shall be
obligated to repurchase such Initial Contract or Subsequent Contract in
accordance with Section 2.3.

                                   ARTICLE III

                    Administration and Servicing of Contracts

         SECTION 3.1. Duties of Servicer. The Servicer shall manage, service,
administer, and make collections on the Contracts. The Servicer agrees that its
servicing of the Contracts shall be carried out in accordance with reasonable
care and, to the extent more exacting, the procedures used by the Servicer in
respect of such contracts serviced by it for its own account; provided, however,
that, subject to Section 3.2 as to extensions, the Servicer shall not release or
waive the right to collect the unpaid balance of any Contract. The Servicer's
duties shall include collection and posting of all payments, responding to
inquiries of Obligors on the Contracts, investigating delinquencies, sending
payment coupons to Obligors, reporting tax information to Obligors, accounting
for collections, furnishing monthly and annual statements to the Trustee and the
Insurer with respect to distributions and the preparation of U.S. Grantor Trust
Tax Returns (Form 1041) for the Trustee to sign and file on an annual basis,
based on a tax year for the Trust that is the calendar year and any other tax
forms required by any federal, state or local tax authority including with
respect to original issue discount, if any. The Servicer shall have, subject to
the terms hereof, full power and authority, acting alone, and subject only to
the specific requirements and prohibitions of this Agreement, to do any and all
things in connection with such managing, servicing, administration, and
collection that it may deem necessary or desirable; provided, however, that the
Servicer shall commence repossession efforts in respect of any Financed Vehicle
any payment on the related Contract of which is four or more months delinquent.
Without limiting the generality of the foregoing, but subject to the provisions
of this Agreement, the Servicer is authorized and empowered by the Trustee to
execute and deliver, on behalf of itself, the Trust, the Insurer, the
Certificateholders, or the Trustee or any of them, any and all instruments of
satisfaction or cancellation, or partial or full release or discharge, and all
other comparable instruments, with respect to the Contracts or to the Financed
Vehicles. The Trustee shall furnish the Servicer any documents necessary or
appropriate to enable the Servicer to carry out its servicing and administrative
duties hereunder. The Servicer may engage agents and subservicers to fulfill its
duties hereunder; provided, however, that the Servicer shall remain at all times
personally liable for the acts (and failures to act) of such agents and
subservicers.

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

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


                                       37
<PAGE>   42
         Subject to Section 4.2(a) respecting deposits in the Payahead Account,
the Servicer shall deposit in or credit to the Collection Account within two
Business Days of receipt all collections of Monthly P&I due after the Cut-Off
Date received by it on the Contracts together with the proceeds of all Full
Prepayments on all Contracts and all partial prepayments on Simple Interest
Contracts, and any accompanying interest. The Servicer shall likewise deposit in
the Collection Account within two Business Days of receipt all Net Liquidation
Proceeds and Net Insurance Proceeds. As of the last day of each Collection
Period, all amounts received in each Collection Period shall be applied by the
Servicer with respect to each Contract, first, to the Servicer as additional
servicing compensation any amounts due for late fees, extension fees or similar
charges, second to the payment of Monthly P&I, and third, in the case of Rule of
78's Contracts, to the Payahead Account. The foregoing requirements for deposit
in the Collection Account are exclusive, it being understood that collections in
the nature of late payment charges or extension fees may, but need not be
deposited in the Collection Account and may be retained by the Servicer as
additional servicing compensation.

         With respect to payments of Monthly P&I made by Obligors to the
Servicer's lock box, the Servicer shall direct the Person maintaining the lock
box to deposit the amount collected on the Contracts within one Business Day to
the Clearing Account. Such amounts shall be withdrawn from the Clearing Account
and deposited in the Collection Account no later than the next following
Business Day.

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

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

         SECTION 3.2. Collection of Contract Payments. The Servicer shall use
its best efforts to collect all payments called for under the terms and
provisions of the Contracts as and when the same shall become due and shall use
its best efforts to cause each Obligor to make all


                                       38
<PAGE>   43
payments in respect of his or her Contract to the Servicer. Consistent with the
foregoing, the Servicer may in its discretion (i) waive any late payment charges
in connection with delinquent payments on a Contract or prepayment charges and
(ii) in order to work out a default or an impending default due to the financial
condition of an Obligor, grant up to three extensions of the Due Date of any
payment for periods of 30 days or less, such that the Maturity Date of no
Contract shall, under any circumstances, extend more than 90 days past the
originally scheduled date of the last payment on such Contract but in no event
beyond the Final Distribution Date. The Servicer shall not extend the Maturity
Date of a Contract except as provided in clause (ii) of the preceding sentence.
Except as explicitly permitted by this paragraph, the Servicer shall not change
any material term of a Contract, including but not limited to the interest rate,
the payment amounts or due dates, or the property securing such Contract.

         SECTION 3.3. Realization Upon Contracts. The Servicer shall use its
best efforts, consistent with the servicing standard specified in Section 3.1,
to repossess or otherwise convert the ownership of the Financed Vehicle securing
any Contract as to which no satisfactory arrangements can be made for collection
of delinquent payments. Such servicing procedures may include reasonable efforts
to realize upon any recourse to Dealers and selling the Financed Vehicle at
public or private sale. In connection with such repossession or other
conversion, the Servicer shall follow such practices and procedures as it shall
deem necessary or advisable and as shall be normal and usual for prudent holders
of retail installment sales contracts and as shall be in compliance with all
applicable laws, and, in connection with the repossession of any Financed
Vehicle or any contract in default, may commence and prosecute any proceedings
in respect of such Contract in its own name or, if the Servicer deems it
necessary, in the name of the Trust or on behalf of the Trust. The Servicer's
obligations under this Section are subject to the provision that, in the case of
damage to a Financed Vehicle from an uninsured cause, the Servicer shall not be
required to expend its own funds in repairing such motor vehicle unless it shall
determine (i) that such restoration will increase the proceeds of liquidation of
the related Contract, after reimbursement to itself for such expenses and (ii)
that such expenses will be recoverable by it either as Liquidation Expenses or
as expenses recoverable under an applicable insurance policy. The Servicer shall
be responsible for all other costs and expenses incurred by it in connection
with any action taken in respect of a Defaulted Contract; provided, however,
that it shall be entitled to reimbursement of such costs and expenses to the
extent they constitute Liquidation Expenses or expenses recoverable under an
applicable insurance policy. All Net Liquidation Proceeds and Net Insurance
Proceeds shall be deposited directly in or credited to the Collection Account
(without deposit in any intervening account) to the extent required by Section
4.2.

         SECTION 3.4. Insurance. The Servicer shall cause to be maintained the
Blanket Insurance Policy with the Trustee as the named payee thereunder with
respect to the Contracts.

         SECTION 3.5. Maintenance of Security Interests in Financed Vehicles.
The Servicer shall take such steps as are necessary to maintain continuous
perfection and priority of the security interest created by each Contract in the
related Financed Vehicle, including but not limited to, obtaining the execution
by the related Obligor and the recording, registering, filing, re-recording,
re-registering, and refiling of all security agreements, financing statements,
continuation statements or other instruments as are necessary to maintain the
security interest


                                       39
<PAGE>   44
granted by such Obligor under each respective Contract. The Trustee hereby
authorizes the Servicer to take such steps as are necessary to re-perfect such
security interest on behalf of the Trust in the event of the relocation of a
Financed Vehicle or for any other reason. In the event that the assignment of a
Contract to the Trust is insufficient, without a notation on the related
Financed Vehicle's certificate of title (or, in the case of the State of
California, the electronic title record), or without fulfilling any additional
administrative requirements under the laws of the state in which the Financed
Vehicle is located, to grant to the Trust a perfected security interest in the
related Financed Vehicle, the Servicer hereby agrees that the Servicer's listing
as the secured party on the certificate of title (or, in the case of the State
of California, the electronic title record) is deemed to be in its capacity as
agent of the Trust and further agrees to hold such certificate of title (or, in
the case of the State of California, the electronic title record) as the
Trustee's agent and custodian; provided that the Servicer shall not make, nor
shall the Trustee or Certificateholders have the right to require that the
Servicer make, any such notation on the related Financed Vehicles' certificate
of title (or, in the case of the State of California, the electronic title
record) or fulfill any such additional administrative requirement of the laws of
the state in which a Financed Vehicle is located.

         SECTION 3.6. Covenants, Representations and Warranties of Servicer. The
Servicer hereby makes the following covenants, representations and warranties on
which the Trustee shall rely accepting the Contracts in trust and authenticating
the Certificates.

         (a)      The Servicer covenants as to the Contracts:

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

                  (ii) the Servicer shall not impair the rights of the Trust in
         the Contracts;

                  (iii) the Servicer shall not increase the number of payments
         under a Contract, nor increase the amount financed under a Contract,
         nor extend or forgive payments on a Contract, except as provided in
         Section 3.2; and

                  (iv) the Servicer may consent to the sale or transfer by an
         Obligor of any Financed Vehicle if the original Obligor under the
         related Contract remains liable under such Contract and the transferee
         assumes all of the Obligor's obligations thereunder.

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

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

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

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

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

                  (v) there are no actions, suits or proceedings pending or, to
         the knowledge of the Servicer, threatened against or affecting the
         Servicer, before or by any court, administrative agency, arbitrator or
         governmental body with respect to any of the transactions contemplated
         by this Agreement, or which will, if determined adversely to the
         Servicer, materially and adversely affect it or its business, assets,
         operations or condition, financial or otherwise, or adversely affect
         the Servicer's ability to perform its obligations under this Agreement.
         The Servicer is not in default with respect to any order of any court,
         administrative agency, arbitrator or governmental body so as to
         materially and adversely affect the transactions contemplated by the
         above-mentioned documents; and

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

         SECTION 3.7. Purchase of Contracts Upon Breach of Covenant. The
Servicer or the Trustee shall inform the other party and the Insurer promptly,
in writing, upon the discovery of any breach of the representation and
warranties set forth in Section 3.6 and the covenants set forth in Section 3.5.
Unless the breach shall have been cured within 30 days following such discovery
or receipt of notice of such breach, the Servicer shall purchase any Contract
materially


                                       41

Contract, the Servicer shall remit the Repurchase Amount on the Business Day
preceding the Servicer Report Date next succeeding the end of such 30-day cure
period in the manner specified in Section 4.4. The sole remedy of the Trustee,
the Trust, or the Certificateholders with respect to a breach pursuant to
Section 3.5 (other than as specified therein) and Section 3.6 shall be to
require the Servicer to purchase Contracts pursuant to this Section 3.7;
provided, however, that the Servicer shall indemnify the Trustee and its
officers, directors, agents and employees, the Insurer, the Trust and the
Certificateholders against all costs, expenses, losses damages, claims and
labilities, including reasonable fees and expenses of counsel, which may be

arising out of the events or facts giving rise to such breach.

shall be entitled (i) to retain all late payment charges, extension fees and
similar items paid in respect of Contracts, (ii) to receive, in respect of each
Rule of 78's Contract that is prepaid in full prior to its Maturity Date, the

in accordance with the Rule of 78's method) exceeds the Scheduled Balance of
such Contract at the time of such prepayment and (iii) to receive all investment
earnings on funds credited to the Collection Account; provided, however, that
the Servicer agrees that each amount payable to it pursuant to clause (ii) of
this Section 3.8 shall be deposited in the Spread Account and applied in
accordance with the Insurance Agreement. The Servicer shall pay all expenses
incurred by it in connection with its servicing activities hereunder and shall
not be entitled to reimbursement of such expenses except to the extent provided
in Section 3.3.

made by a third party with respect to the Contracts, shall assume, with the
consent of the Trustee, the defense of any such claim and shall pay all expenses

                 Distributions; Statements to Certificateholders

         SECTION 4.1.       Accounts.

         (a) Prior to the Closing Date, the Servicer shall open, at a depository
institution (which may be the Trustee), an account denominated "Collection
Account--GT 1996-4, Bankers Trust Company, Trustee" (the "Collection Account")
and an account denominated "Payahead Account--GT 1996-4, Bankers Trust Company,
as agent" (the "Payahead Account") for the benefit of the Trustee on behalf of
the Obligors and the Certificateholders, as their interests may appear, and an
account denominated "Pre-Funding Account--GT 1996-4, Bankers Trust Company,
Trustee" for the benefit of the Certificateholders (the "Pre-Funding Account,"
and, collectively, with the Collection Account and the Payahead Account, the
"Accounts"). The Accounts shall be Eligible Accounts. The Servicer shall give
the Trustee and the Insurer at least five Business Days' written notice of any
change in the location of any Account and any related account identification
information. All moneys deposited in or credited to, from time to time, the
Collection Account and Pre-Funding Account shall be part of the Trust and all
moneys deposited in or credited to, from time to time, the Collection Account
and Pre-Funding Account shall be invested by the Trustee in Eligible Investments
pursuant to Section 4.1(c) and 4.1(d), respectively.

         (b) If as of the last day of a Collection Period a payment in an amount
less than the scheduled payment of Monthly P&I has been made for a Rule of 78's
Contract with respect to which amounts have been deposited in or credited to the
Payahead Account in a preceding Collection Period in accordance with Sections
3.1 and 4.2(a), the Servicer shall withdraw from the Payahead Account and
deposit into the Collection Account by the fifth Business Day preceding the
Distribution Date immediately succeeding such Collection Period the amount of
such Monthly P&I, to the extent available from amounts deposited in or credited
to the Payahead Account with respect to such Contract. Amounts on deposit in the
Payahead Account shall be invested by Bankers Trust Company upon the written
direction of the Servicer in Eligible Investments which mature not later than
the fifth Business Day prior to the Distribution Date to which such amounts
relate, and any earnings on such Eligible Investments shall be payable to the
Servicer. The Payahead Account and all amounts on deposit therein or credited
thereto shall not be considered part of the Trust Estate.

         (c) All funds in the Collection Account shall be invested by the
Trustee in Eligible Investments. The Insurer shall direct the Trustee in writing
to invest funds in the Collection Account in Eligible Investments; provided that
in the absence of such directions from the Insurer, the Servicer may so direct
the Trustee. All such investments shall be in the name of the Trustee as trustee
of the Trust. All income or other gain from investment of monies deposited in or
credited to the Collection Account shall be paid by the Trustee to the Servicer
monthly, unless earlier requested by the Servicer. The maximum permissible
maturities of any such investments pursuant to this Section 4.1(c) on any date
shall not be later than the Servicer Report Date preceding the Distribution Date
next succeeding the date of such investment; provided, however, that such funds
may be invested by the Trustee in Eligible Investments of


                                       47
<PAGE>   52
the entity that is serving as Trustee (or an entity which meets the criteria in
clauses (b) or (c) of the definition of Eligible Account) that mature on the
Business Day prior to such Distribution Date. No such investment may be sold
prior to its maturity.

         (d) The Pre-Funded Amount shall be invested by the Trustee in Eligible
Investments at the written direction of the Insurer, provided, that if on any
date the Insurer has not provided instructions with respect to such investments
by 10:00 a.m. New York City time, the Trustee shall invest such funds in the
last Eligible Investment in which such funds were invested. All such investments
shall be in the name of the Trustee as trustee of the Trust. All income or other
gain from investment of the Pre-Funded Amount shall be deposited in or credited
to the Collection Account no later than the Servicer Report Date preceding any
Distribution Date during (or immediately following) the Funding Period. The
maximum permissible maturities of any such investments shall be not later than
the next Business Day. [Is more aggressive investing possible? ERISA
considerations?]

         SECTION 4.2. Collections; Transfer to Payahead Account; Realization
Upon Surety Bond; Net Deposit.

         (a) Subject to Section 4.4 below, the Servicer shall remit or credit
all payments on a daily basis, within two Business Days of receipt, by or on
behalf of the Obligors on the Contracts and all Net Liquidation Proceeds and Net
Insurance Proceeds to the Collection Account. The Servicer shall deposit the
Yield Supplement Amount with respect to each Collection Period to the Collection
Account no later than the immediately following Servicer Report Date provided,
that if the Servicer fails to make such deposit, the Yield Supplement Agent,
pursuant to Section 4.6(a)(ii), shall withdraw the Yield Supplement Amount from
the Yield Supplement Reserve Account on the Servicer Report Date and deposit
such amount into the Collection Account. Prior to the Servicer Report Date,
amounts with respect to Rule of 78's Contracts which had been deposited in or
credited to the Collection Account pursuant to the next preceding sentence
during the preceding Collection Period shall be deposited in or credited to the
Payahead Account (in accordance with the Distribution Date Statement) to the
extent that such amounts are installments of Monthly P&I which are due in a
Collection Period relating to a Distribution Date subsequent to the Distribution
Date immediately succeeding such Collection Period.

         (b) Based upon the report referenced in Section 3.9(b) delivered by the
Servicer to the Trustee on the Servicer Report Date, the Servicer shall
determine the Collection Account Amount Available, compare such amount to the
amounts required to be distributed pursuant to Section 4.3, and determine the
Policy Claim Amount, if any, which exists with respect to the related
Distribution Date.

         (c) The Trustee shall, no later than 12:00 p.m. New York time on the
third Business Day prior to each Distribution Date, make a claim under the
Surety Bond for the Policy Claim Amount, if any, for such Distribution Date by
delivering to the Insurer and the Bank, with a copy to the Servicer, by hand
delivery, telex or facsimile transmission, a Deficiency Notice specifying the
Policy Claim Amount. In making any such claim, the Trustee shall comply with all
the terms and conditions of the Surety Bond. The notice of such claim shall
direct the


                                       48
<PAGE>   53
Insurer and Bank to remit such Policy Claim Amount (no later than 11:00 a.m. on
the Business Day immediately preceding such Distribution Date) to the Trustee
for deposit in the Collection Account.

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

         SECTION 4.3.       Distributions.

         (a) On the Business Day immediately preceding each Distribution Date,
the Trustee shall transfer, or cause to be transferred, to the Paying Agent for

Account, the amounts set forth in clauses (ii) and (iii) below, to the extent
that such amounts are available after giving effect to the amount to be
distributed on the Distribution Date set forth in clause (i).

         On each Distribution Date, the following amounts shall be distributed
from the Amount Available in the following order of priority in accordance with
the Distribution Date Statement:

         Servicer, the Servicing Fee to the extent of the Amount Available
         allocable to interest from any source under the Recomputed Actuarial
         Method in the case of Rule of 78's Contracts and under the Simple
         Interest Method in the case of Simple Interest Contracts;

                  (ii) by the Paying Agent from the Distribution Account, to the
         Certificateholders, the Interest Distribution to the extent of the

         Supplement Reserve Account;

                  (iv) On each Subsequent Closing Date, upon the satisfaction of

                                The Certificates

         SECTION 5.1. The Certificates. Unless otherwise specified in the
Agreement, the Certificates shall be substantially in the form set forth in
Exhibit B and shall be issued in denominations of $1,000 and integral multiples
thereof; provided, however, that one Certificate may be issued in a denomination
that includes any residual portion of the Original Pool/Pre- Funding Amount. The
Certificates shall be executed on behalf of the Trust by manual or facsimile
signature of a Responsible Officer of the Trustee. Certificates bearing the
manual or facsimile signatures of individuals who were, at the time when such
signatures shall have been affixed, authorized to sign on behalf of the Trust,
shall be valid and binding obligations of the Trust, notwithstanding that such
individuals or any of them shall have ceased to be so authorized prior to the
authentication and delivery of such Certificates or did not hold such offices at
the date of the issuance of such Certificates. No Certificate shall entitle its
holder to any benefit under the Agreement, or shall be valid for any purpose,
unless there shall appear on such Certificate a certificate of authentication
substantially in the form set forth in Exhibit B hereto executed by the Trustee
by manual signature; such authentication shall constitute conclusive evidence
that such Certificate shall have been duly authenticated and delivered
hereunder. All Certificates shall be dated the date of their authentication.
Upon issuance pursuant to the terms of the Agreement, the Certificates will be
entitled to the benefits of the Agreement.

         SECTION 5.2. Execution, Authentication and Delivery of Certificates. In
exchange for the Contracts and the other assets of the Trust as of the Closing
Date, simultaneously with the sale, assignment and transfer to the Trustee of
the Contracts, the delivery to the Trustee of the Contract Documents, the
constructive delivery to the Trust of the Contract Files other than the Contract
Documents and the delivery to the Trustee of the other components of the Trust
(other than the Subsequent Contracts and related property), the Trustee shall
deliver to, or upon the written order of, the Seller, Certificates duly executed
by the Trustee, on behalf of the Trust, and authenticated by the Trustee in
authorized denominations equaling in the aggregate the Original Pool/Pre-Funding
Amount, and evidencing the entire ownership of the Trust.

         SECTION 5.3. Registration of Transfer and Exchange of Certificates. The
Trustee shall cause to be kept at the office or agency to be maintained by a
transfer agent and certificate registrar (the "Transfer Agent" and "Certificate
Registrar") and maintain, pursuant to Section 5.7, a Certificate Register in
which, subject to such reasonable regulations as it may prescribe, the Trustee
shall provide for the registration of Certificates and of transfers and
exchanges of Certificates as herein provided. The Trustee shall be the initial
Transfer Agent and Certificate Registrar.

         Subject to the other provisions of this Section , upon surrender for
registration or transfer of any Certificate at the Corporate Trust Office, the
Trustee shall execute on behalf of the Trust,


                                       53
<PAGE>   58
authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Certificates in authorized denominations of a like
aggregate amount. At the option of a Certificateholder, Certificates may be
exchanged for other Certificates of authorized denominations of a like aggregate
amount at the Corporate Trust Office.

         Every Certificate presented or surrendered for registration of transfer
or exchange shall be accompanied by a written instrument of transfer in form
satisfactory to the Trustee and the Certificate Registrar duly executed by the
Holder. Each Certificate surrendered for registration of transfer and exchange
shall be cancelled and subsequently destroyed by the Trustee.

         No service charge shall be made for any registration of transfer or
exchange of Certificates, but the Trustee may require payment of a sum
sufficient to cover any tax of governmental charge that may be imposed in
connection with any transfer or exchange of Certificates.

         SECTION 5.4. Mutilated, Destroyed, Lost or Stolen Certificates. If (i)
any mutilated Certificate shall be surrendered to the Certificate Registrar, or
if the Certificate Registrar shall receive evidence to its satisfaction of the
destruction, loss, or theft of any Certificate and (ii) there shall be delivered
to the Certificate Registrar or the Trustee such security or indemnity as may be
required by them to save each of them harmless, then in the absence of notice
that such Certificate shall have been acquired by a bona fide purchaser, the
Trustee on behalf of the Trust shall execute and the Trustee shall authenticate
and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost
or stolen Certificate, a new Certificate of like tenor and denomination. In
connection with the issuance of any new Certificate under this Section 5.4, the
Trustee and the Certificate Registrar may require the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection therewith. Any duplicate Certificate issued pursuant to this Section
5.4 shall constitute conclusive evidence of ownership in the Trust, as if
originally issued, whether or not the lost, stolen, or destroyed Certificate
shall be found at any time.

         SECTION 5.5. Persons Deemed Owners. Prior to due presentation of a
Certificate for registration or transfer, the Trustee or the Certificate
Registrar may treat the Person in whose name any Certificate shall be registered
as the owner of such Certificate for the purpose of receiving distributions
pursuant to Section 4.3 and for all other purposes whatsoever, and neither the
Trustee nor the Certificate Registrar shall be bound by any notice to the
contrary.

         SECTION 5.6. Access to List of Certificateholders' Names and Addresses.
The Trustee shall furnish or cause to be furnished to the Servicer, within 15
days after receipt by the Trustee of a request therefor from the Servicer in
writing, a list of the names and addresses of the Certificateholders as of the
most recent Record Date. If three or more Certificateholders, or one or more
Holders of Certificates evidencing in the aggregate not less than 25% of the
Pool/Pre-Funding Balance (hereinafter referred to as "applicants"), apply in
writing to the Trustee, and such application states that the applicants desire
to communicate with other Certificateholders with respect to their rights under
the Agreement or under the Certificates and such application shall be
accompanied by a copy of the communication that such applicants propose to
transmit, then the Trustee shall, within five Business Days after the receipt of
such


                                       54
<PAGE>   59
application, afford such applicants access during normal business hours to the
current list of Certificateholders. Each Certificateholder, by receiving and
holding a Certificate, shall be deemed to have agreed to hold neither the
Servicer nor the Trustee accountable by reason of the disclosure of its name and
address, regardless of the source from which such information was derived.

         SECTION 5.7. Maintenance of Office or Agency. The Trustee shall
maintain in the Borough of Manhattan, the City of New York, an office or offices
or agency or agencies where Certificates may be surrendered for registration of
transfer or exchange and where notices and demands to or upon the Trustee in
respect of the Certificates and the Agreement may be served. The Trustee
initially designated the Corporate Trust Office as specified in the Agreement as
its office for such purposes. The Trustee shall give prompt written notice to
the Servicer and to Certificateholders of any change in the location of the
Certificate Register or any such office or agency.

         SECTION 5.8. Book-Entry Certificates. The Certificates (other than a
Certificate representing any residual portion of the Pool/Pre-Funding Balance),
upon original issuance, shall be issued in the form of typewritten Certificates
representing the Book-Entry Certificates, to be delivered to The Depository
Trust Company, the initial Clearing Agency, by the Seller or on its behalf. The
Certificates shall initially be registered on the Certificate Register in the
name of Cede & Co., the nominee of the initial Clearing Agency, and no
Certificate Owner will receive a definitive certificate representing such
Certificate Owner's interest in the Certificates, except as provided in Section
5.10. Unless and until definitive, fully registered Certificates ("Definitive
Certificates") have been issued to Certificateholders pursuant to Section 5.10:

                  (i) the provisions of this Section 5.8 shall be in full force
         and effect;

                  (ii) the Seller, the Servicer, the Paying Agent, the Transfer
         Agent and Certificate Registrar and the Trustee may deal exclusively
         with the Clearing Agency for all purposes (including the making of
         distributions in respect of the Certificates and the taking of actions
         by the Certificateholders) as the authorized representative of the
         Clearing Agency Participants and the Certificate Owners;

                  (iii) to the extent that the provisions of this Section 5.8
         conflict with any other provisions of the Agreement, the provisions of
         this Section 5.8 shall control;

                  (iv) the rights of Certificate Owners shall be exercised only
         through the Clearing Agency (or to the extent Certificate Owners are
         not Clearing Agency Participants through the Clearing Agency
         Participants through which such Certificate Owners own Book-Entry
         Certificates) and shall be limited to those established by law and
         agreements between such Certificate Owners and the Clearing Agency
         and/or the Clearing Agency Participants and all references in the
         Agreement to actions by Certificateholders shall refer to actions taken
         by the Clearing Agency upon instructions from the Clearing Agency
         Participants, and all references in the Agreement to distributions,
         notices, reports and statements to Certificateholders shall refer to
         distributions, notices, reports and statements to the Clearing Agency
         or its nominee, as


                                       55
<PAGE>   60
         registered holder of the Certificates, as the case may be, for
         distribution to Certificate Owners in accordance with the procedures of
         the Clearing Agency; and

                  (v) pursuant to the Depository Agreement, the initial Clearing
         Agency will make book-entry transfers among the Clearing Agency
         Participants and receive and transmit distributions of principal and
         interest on the Certificates to the Clearing Agency Participants, for
         distribution by such Clearing Agency Participants to the Certificate
         Owners or their nominees.

         The Clearing Agency Participants shall have no rights under this
Agreement under or with respect to any of the Certificates held on their behalf
by the Clearing Agency, and the Clearing Agency may be treated by the Trustee,
and its agents, employees, officers and directors, as the absolute owner of the
Certificates for all purposes whatsoever.

         SECTION 5.9. Notices to Clearing Agency. Whenever notice or other
communication to the Certificateholders is required under the Agreement, unless
and until Definitive Certificates shall have been issued to Certificate Owners
pursuant to Section 5.10, the Trustee and the Paying Agent shall give all such
notices and communications specified herein to be given by it to
Certificateholders to the Clearing Agency.

         SECTION 5.10. Definitive Certificates. If (i)(A) the Seller advises the
Trustee in writing that the Clearing Agency is no longer willing or able
properly to discharge its responsibilities under the Depository Agreement, and
(B) the Trustee or the Seller is unable to locate a qualified successor or (ii)
after the occurrence of an Event of Default, Certificate Owners representing
beneficial interests aggregating more than 50% of the Pool/Pre-Funding Balance
advise the Clearing Agency and the Trustee (and the Clearing Agency shall notify
the Trustee in writing thereof) through the Clearing Agency Participants in
writing that the continuation of a book-entry system through the Clearing Agency
is no longer in the best interests of the Certificate Owners, the Trustee shall
notify the Clearing Agency of the occurrence of any event described in clauses
(i) and (ii) above and of the availability of Definitive Certificates to
Certificate Owners requesting the same. Upon surrender to the Transfer Agent and
Certificate Registrar by the Clearing Agency of Certificates registered in the
name of such Clearing Agency or its nominee, accompanied by re-registration
instructions from the Clearing Agency for registration of the Definitive
Certificates, the Trustee shall execute on behalf of the Trust, authenticate and
(if the Transfer Agent and Certificate Registrar is different than the Trustee,
then the Transfer Agent and Certificate Registrar shall) deliver Definitive
Certificates. The Servicer shall arrange for, and will bear all costs of, the
printing and issuance of such Definitive Certificates. None of the Seller, the
Servicer, the Transfer Agent and Certificate Registrar or the Trustee shall be
liable for any delay in delivery of such instructions and may conclusively rely
on, and shall be protected in relying on such instruction. Upon the issuance of
Definitive Certificates, all references herein to obligations imposed upon or to
be performed by the Clearing Agency shall be deemed to be imposed upon and
performed by the Transfer Agent and Certificate Registrar, to the extent
applicable with respect to such Definitive Certificates and the Trustee, the
Paying Agent and the Transfer Agent and Certificate Registrar shall recognize
the Holders of the Definitive Certificates as Certificateholders hereunder.


                                       56
<PAGE>   61
         SECTION 5.11.      Appointment of Paying Agent.

         (a) The Paying Agent shall have the revocable power to withdraw funds
from the Collection Account and make distributions to the Certificateholders.
The Trustee may revoke such power and remove the Paying Agent, if the Trustee
determines in its sole discretion that the Paying Agent shall have failed to
perform its obligations under the Agreement in any material respect or for other
good cause. The Paying Agent shall initially be Bankers Trust Company. Bankers
Trust Company shall be permitted to resign as Paying Agent upon 30 days' written
notice to the Servicer and the Trustee. In the event that Bankers Trust Company
shall no longer be the Paying Agent, the Trustee shall appoint a successor to
act as Paying Agent, which shall be a bank or trust company.

         (b) The Trustee shall cause the Paying Agent (if other than itself) to
execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee that such Paying Agent will hold all sums, if any,
held by it for payment to the Certificateholders, and the Trustee in trust for
the benefit of the Certificateholders or other party entitled thereto until such
sums shall be paid to such Certificateholders or other party entitled thereto
and shall agree, and if the Trustee is the Paying Agent it hereby agrees, that
it shall comply with all requirements of the Code regarding the withholding by
the Trustee of payments in respect of federal income taxes due from Certificate
Owners.

         (c) Bankers Trust Company in its capacity as initial Paying Agent
hereunder agrees that it (i) will hold all sums held by it hereunder for payment
to the Certificateholders, in trust for the benefit of the Certificateholders or
other party entitled thereto until such sums shall be paid to such
Certificateholders or other party entitled thereto and (ii) shall comply with
all requirements of the Code regarding the withholding by the Trustee of
payments in respect of federal income taxes due from Certificate Owners.

         SECTION 5.12.      Authenticating Agent.

         (a) The Trustee may appoint one or more authenticating agents (each an
"Authenticating Agent") with respect to the Certificates which shall be
authorized to act on behalf of the Trustee in authenticating the Certificates in
connection with the issuance, delivery, registration of transfer, exchange or
repayment of the Certificates. Whenever reference is made in this Agreement to
the authentication of Certificates by the Trustee or the Trustee's certificate
of authentication, such reference shall be deemed to include authentication on
behalf of the Trustee by an authenticating agent and a certificate of
authentication executed on behalf of the Trustee by an authenticating agent. Any
authenticating agent appointed by the Trustee shall require the consent of the
Seller, which consent may not be unreasonably withheld.

         (b) Any institution succeeding to the corporate agency business of an
authenticating agent shall continue to be an authenticating agent without the
execution or filing of any paper or any further act on the part of the Trustee
or such authenticating agent.

         (c) An authenticating agent may at any time resign by giving written
notice of resignation to the Trustee and the Seller. The Trustee may at any time
terminate the agency of


                                       57
<PAGE>   62
an authenticating agent by giving notice of termination to such authenticating
agent and to the Seller. Upon receiving such a notice of resignation or upon
such a termination, or in case at any time an authenticating agent shall cease
to be acceptable to the Trustee or the Seller, the Trustee promptly may appoint
a successor authenticating agent with the consent of the Seller. Any successor
authenticating agent upon acceptance of its appointment hereunder shall become
vested with all the rights, powers and duties of its predecessor hereunder, with
like effect as if originally named as an authenticating agent. Any successor
authenticating agent appointed by the Trustee shall require the consent of the
Seller, which consent may not be unreasonably withheld.

         (d) The Servicer shall pay the Authenticating Agent from time to time
reasonable compensation for its services under this Section 5.12.

         (e) Pursuant to an appointment made under this Section 5.12, the
Certificates may have endorsed thereon, in lieu of the Trustee's certificate of
authentication, an alternate certificate of authentication in substantially the
following form:

         This is one of the certificates referred to in the within mentioned
Agreement.

                                            _____________________________,
                                              as Trustee

         SECTION 5.13. Actions of Certificateholders. Any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
the Agreement to be given or taken by Certificateholders may be embodied in and
evidenced by one or more instruments of substantially similar tenor signed by
such Certificateholders in person or by an agent duly appointed in writing; and
except as herein otherwise expressly provided, such action shall become
effective when such instrument or instruments are delivered to the Trustee and,
when required, to the Seller or the Servicer. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of the Agreement and conclusive in favor of the Trustee, the Seller and
the Servicer, if made in the manner provided in this Section 5.13.

                                   The Seller

         SECTION 6.1. Liability of Seller; Indemnities. The Seller shall be
liable in accordance herewith only to the extent of the obligations specifically
undertaken by the Seller under the Agreement.

         The Seller shall indemnify, defend, and hold harmless the Trustee and
its officers, directors, agents and employees and the Trust from and against any
taxes that may at any time be asserted against the Trustee or the Trust with
respect to, and as of the date of, the sale of the Contracts to the Trustee or
the issuance and original sale of the Certificates, including any sales, gross
receipts, general corporation, tangible personal property, privilege, or license
taxes (but not, in case of the Trust, including any taxes asserted with respect
to ownership of the Contracts or federal or other income taxes arising out of
the transactions contemplated by the Agreement) and costs and expenses in
defending against the same.

         The Seller shall indemnify, defend, and hold harmless the Trustee and
its officers, directors, agents and employees from and against any loss,
liability or expense incurred by reason of the Seller's willful misfeasance, bad
faith, or negligence in the performance of its duties hereunder, or by reason of
reckless disregard of its obligations and duties hereunder.

         The Seller shall indemnify, defend and hold harmless the Trustee and
its officers, directors, agents and employees and the Trust from and against all
costs, expenses, losses, claims, damages, and liabilities arising out of or
incurred in connection with the acceptance or performance of the trusts and
duties herein contained, except to the extent that such cost, expense, loss,
claim, damage or liability: (i) shall be due to the willful misfeasance, bad
faith, or gross negligence of the Trustee; or (ii) shall arise from the
Trustee's breach of any of its representations or warranties set forth in
Section 9.14.

         Indemnification under this Section 6.1 shall include, without
limitation, reasonable fees and expenses of counsel and expenses of litigation.
If the Seller shall have made any indemnity payments to the Trustee pursuant to
this Section and the Trustee thereafter shall collect any of such amounts from
others, the Trustee shall repay such amounts to the Seller, without interest.

         SECTION 6.2. Merger or Consolidation of, or Assumption of the
Obligations of, Seller. The Seller shall not consolidate with or merge into any
other corporation or convey, transfer or lease substantially all of its assets
as an entirety to any Person unless the corporation formed by such consolidation
or into which the Seller has merged or the Person which acquires by conveyance,
transfer or lease substantially all the assets of the Seller as an entirety, can
lawfully perform the obligations of the Seller hereunder and executes and
delivers to the Insurer and the Trustee an agreement in form and substance
reasonably satisfactory to the Trustee and the Insurer, which contains an
assumption by such successor entity of the due and punctual performance and
observance of each covenant and condition to be performed or observed by the
Seller under this Agreement.

<PAGE>   64
         SECTION 6.3. Limitation on Liability of Seller and Others. The Seller
and any director or officer or employee or agent of the Seller may rely in good
faith on any document of any kind, prima facie properly executed and submitted
by any Person respecting any matters arising hereunder. The Seller shall not be
under any obligation to appear in, prosecute, or defend any legal action that
shall not be incidental to its obligations under this Agreement, and that in its
opinion may involve it in any expense or liability.

         SECTION 6.4. Seller Not to Resign. Subject to the provisions of Section
6.2, the Seller shall not resign from the obligations and duties hereby imposed
on it as Seller under this Agreement.

         SECTION 6.5. Seller May Own Certificates. The Seller and any Person
controlling, controlled by, or under common control with the Seller may in its
individual or any other capacity become the owner or pledgee of Certificates
with the same rights as it would have if it were not the Seller or an affiliate
thereof, except as otherwise provided in the definition of "Certificateholder"
specified in Section 1.1. Certificates so owned by or pledged to the Seller or
such controlling or commonly controlled Person shall have an equal and
proportionate benefit under the provisions of the Agreement, without preference,
priority, or distinction as among all of the Certificates.


                                   ARTICLE VII

                                  The Servicer

         SECTION 7.1. Liability of Servicer; Indemnities. The Servicer shall be
liable in accordance herewith only to the extent of the obligations specifically
undertaken by the Servicer under the Agreement.

         Such obligations shall include the following:

         (a) the Servicer shall defend, indemnify, and hold harmless the Trustee
and its officers, directors, agents and employees, the Trust, the Insurer and
the Certificateholders from and against any and all costs, expenses, losses,
damages, claims, and liabilities, arising out of or resulting from the use or
operation by the Servicer or any Affiliate thereof of a Financed Vehicle;

         (b) the Servicer shall indemnify, defend and hold harmless the Trustee
and its officers, directors, agents and employees, the Insurer and the Trust
from and against any taxes that may at any time be asserted against the Trustee
or the Trust with respect to the transactions contemplated herein, including,
without limitation, any sales, gross receipts, general corporation, tangible
personal property, privilege, or license taxes (but not including any taxes
asserted with respect to, and as of the date of, the sale of the Contracts to
the Trustee or the issuance and original sale of the Certificates, or asserted
with respect to ownership of the Contracts, or federal or other income taxes
arising out of distributions on the Certificates) and costs and expenses in
defending against the same;


                                       60
<PAGE>   65
         (c) the Servicer shall indemnify, defend and hold harmless the Trustee
and its officers, directors, agents and employees, the Trust, the Insurer and
the Certificateholders from and against any and all costs, expenses, losses,
claims, damages, and liabilities to the extent that such cost, expense, loss,
claim, damage, or liability arose out of, or was imposed upon the Trustee, the
Trust, or the Certificateholders through, the negligence, willful misfeasance,
or bad faith of the Servicer in the performance of its duties under the
Agreement; and

         (d) the Servicer shall indemnify, defend, and hold harmless the Trustee
and the Insurer from and against all costs, expenses, losses, claims, damages,
and liabilities arising out of or incurred in connection with the acceptance or
performance of the trusts and duties herein contained, except to the extent that
such cost, expense, loss, claim, damage, or liability: (i) shall be due to the
willful misfeasance, bad faith, or negligence (except for errors in judgment) of
the Trustee or the Insurer; (ii) relates to any tax other than the taxes with
respect to which either the Seller or Servicer shall be required to indemnify
the Trustee; (iii) shall arise from the Trustee's breach of any of its
representations or warranties set forth in Section 9.13; or (iv) shall be one as
to which the Seller is required to indemnify the Trustee.

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

         SECTION 7.2.       Corporate Existence; Status as Servicer; Merger.

         (a) The Servicer shall keep in full effect its existence, rights and
franchises as a corporation incorporated under the laws of the State of
Delaware, and will obtain and preserve its qualification to do business as a
foreign corporation in each jurisdiction in which such qualification is or shall
be necessary to protect the validity and enforceability of the Contract
Documents and this Agreement.

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

         SECTION 7.3.       Performance of Obligations.

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


                                       61
<PAGE>   66
         (b) The Servicer shall not take any action, or permit any action to be
taken by others, which would excuse any person from any of its covenants or
obligations under any of the Contract Documents or under any other instrument
included in the Trust Estate, or which would result in the amendment,
hypothecation, subordination, termination or discharge of, or impair the
validity or effectiveness of, any of the Contract Documents or any such
instrument, except as expressly provided herein and therein.

         SECTION 7.4.       The Servicer Not to Resign; Assignment.

         (a) The Servicer shall not resign from the duties and obligations
hereby imposed on it except upon determination by its Board of Directors that by
reason of change in applicable legal requirements the continued performance by
the Servicer of its duties under this Agreement would cause it to be in
violation of such legal requirements in a manner which would result in a
material adverse effect on the Servicer or its financial condition, said
determination to be evidenced by a resolution of its Board of Directors to such
effect accompanied by an Opinion of Counsel, satisfactory to the Trustee, to
such effect (subject to Section 8.2 hereof). No such resignation shall become
effective unless and until (i) the Back-up Servicer assumes all of the
Servicer's obligations under this Agreement or (ii) a new servicer acceptable to
the Trustee with the consultation of the Insurer is willing to service the
Contracts, enters into a servicing agreement with the Trustee in form and
substance substantially similar to this Agreement and satisfactory to the
Trustee and the Insurer, and the rating agency or agencies that rated the
Certificates confirm that the selection of such new servicer will not result in
the reduction or withdrawal of the rating of the Certificates assigned to them
by such rating agency or, if the Certificates are rated by more than one rating
agency, each such rating agency. No such resignation by the Servicer shall
affect the obligation of the Servicer to repurchase any Contract pursuant to
Section 3.7.

         (b) Except as specifically permitted hereunder, the Servicer may not
assign this Agreement or any of its rights, powers, duties or obligations
hereunder, provided that the Servicer may assign this Agreement in connection
with a consolidation, merger, conveyance, transfer or lease made in compliance
with Section 7.2(b).

         (c) Except as provided in Sections 7.4(a) and (b), the duties and
obligations of the Servicer under this Agreement shall continue until this
Agreement shall have been terminated as provided in Section 10.1, and shall
survive the exercise by the Trustee or the Insurer of any right or remedy under
this Agreement, or the enforcement by the Trustee, any Certificateholder or the
Insurer of any provision of the Certificates, the Insurance Agreement or this
Agreement.

         (d) The resignation of the Servicer in accordance with this Section 7.4
shall not affect the rights of the Seller hereunder.

         SECTION 7.5. Limitation on Liability of Servicer and Others. Neither
the Servicer nor any of the directors or officers or employees or agents of the
Servicer shall be under any liability to the Trust or the Certificateholders,
except as provided under this Agreement, for any action taken or for refraining
from the taking of any action pursuant to this Agreement or for errors in
judgment; provided, however, that this provision shall not protect the Servicer
or any


                                       62
<PAGE>   67
such person against any liability that would otherwise be imposed by reason of
willful misfeasance, bad faith or negligence (except errors in judgment) in the
performance of duties or by reason of reckless disregard of obligations and
duties under the Agreement. The Servicer and any director or officer or employee
or agent of the Servicer may rely in good faith on any document of any kind
prima facie properly executed and submitted by any Person respecting any matters
arising under this Agreement.

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


                                  ARTICLE VIII

                                     Default

         SECTION 8.1. Events of Default. If any one of the following events
("Events of Default") shall occur and be continuing:

         (a) any failure by the Servicer to deposit in or credit to the
Collection Account, the Payahead Account or the Yield Supplement Reserve Account
any amount required under this Agreement to be so deposited or credited or to
make the distribution required by Section 4.3 that shall continue unremedied for
a period of three Business Days after written notice from the Trustee or the
Insurer is received by the Servicer or discovery by an officer of the Servicer;
or

         (b) the Insurer or the Trustee shall not have received a report in
accordance with Section 3.9 by the fifth Business Day prior to the Distribution
Date with respect to which such report is due; or

         (c) failure on the part of the Seller or the Servicer duly to observe
or to perform in any material respect any other covenants or agreements of the
Seller or the Servicer, set forth in this Agreement, which failure shall (x)
materially and adversely affect the rights of Certificateholders, the Insurer or
the Trustee and (y) continue unremedied for a period of 30 days after the date
on which written notice of such failure, requiring the same to be remedied,
shall have been given (i) to the Seller or the Servicer, as the case may be, by
the Trustee or the Insurer, or (ii) to the Seller or the Servicer, as the case
may be, and to the Trustee by the Holders of Certificates evidencing in the
aggregate not less than 25% of the Pool/Pre-Funding Balance or by the Insurer;
or

         (d) the entry of a decree or order for relief by a court or regulatory
authority having jurisdiction in respect of the Servicer or the Seller in an
involuntary case under the federal bankruptcy laws, as now or hereafter in
effect, or another present or future, federal or state,


                                       63
<PAGE>   68
bankruptcy, insolvency or similar law, or appointing a receiver, liquidator,
assignee, trustee, custodian, sequestrator or other similar official of the
Servicer or the Seller or of any substantial part of its property, or ordering
the winding up or liquidation of the affairs of the Servicer or the Seller and
the continuance of any such decree or order unstayed and in effect for a period
of 60 consecutive days or the commencement of an involuntary case under the
federal bankruptcy laws, as now or hereinafter in effect, or another present or
future federal or state bankruptcy, insolvency or similar law and such case is
not dismissed within 60 days; or

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

         (f) any change of control of the Servicer in violation of the covenant
set forth in Section 7.2 hereof;

         (g) the Servicer shall have failed in the reasonable opinion of the
Insurer to service the Contracts in accordance with the Servicing Standards and
such failure shall have continued unremedied for 30 days after written notice of
such failure shall have been delivered to the Servicer by the Insurer; or

         (h) Any representation, warranty or statement of the Servicer or the
Seller made in this Agreement or any certificate, report or other writing
delivered pursuant hereto shall prove to be incorrect in any material respect as
of the time when the same shall have been made (excluding, however, any
representation or warranty to which Sections 2.2 or 3.6 shall be applicable so
long as the Servicer or the Seller shall be in compliance with Sections 2.3 or
3.7, as the case may be), and the incorrectness of such representation, warranty
or statement has a material adverse effect on the Trust and, within 30 days
after written notice thereof shall have been given to the Servicer or the Seller
by the Trustee or by the Holders of Certificates evidencing in the aggregate at
least 25% of the Pool/Pre-Funding Balance or by the Insurer, the circumstance or
condition in respect of which such representation, warranty or statement was
incorrect shall not have been eliminated or otherwise cured;

then and in each and every case, so long as an Event of Default shall not have
been remedied, either the Trustee, the Insurer or the Holders of Certificates
evidencing in the aggregate not less than 25% of the Pool/Pre-Funding Balance,
by notice then given in writing to the Servicer (and to the Trustee and the
Insurer if given by the Certificateholders) may terminate all of the rights and
obligations of the Servicer under this Agreement. Notwithstanding the foregoing,
in the event that the Insurer is in default under the Surety Bond or is subject
to any Insurer Insolvency, the Insurer shall not have the right to terminate or
cause the termination of the Servicer. On or after the receipt by the Servicer
of such written notice, all authority and power of the Servicer under this
Agreement, whether with respect to the Certificates or the Contracts or
otherwise,


                                       64
<PAGE>   69
shall pass to and be vested in a back-up servicer (the "Back-up Servicer")
selected by the Insurer (unless it is in default under the Surety Bond or is
subject to any Insurer Insolvency); and, without limitation the Back-up Servicer
is hereby authorized and empowered to execute and deliver, on behalf of the
Servicer, as attorney-in-fact or otherwise, any and all documents and other
instruments, and to do or accomplish all other acts or things necessary or
appropriate to effect the purposes of such notice of termination, whether to
complete the transfer and assignment of the Contracts and related documents, to
show the Back-up Servicer as a lienholder or secured party on Title Documents or
financing statements or otherwise. The Servicer shall cooperate with the Back-up
Servicer in effecting the termination of the responsibilities and rights of the
Servicer under this Agreement, including the transfer to the Back-up Servicer
for administration by it of all cash amounts that shall at the time be held by
the Servicer for deposit, shall have been deposited by the Servicer in the
Collection Account or Payahead Account, or shall thereafter be received with
respect to a Contract.

         SECTION 8.2. Notification to Certificateholders. Upon any termination
of, or appointment of a successor to, the Servicer pursuant to this Article
VIII, the Trustee shall give prompt written notice thereof to Certificateholders
at their respective addresses appearing in the Certificate Register.

         SECTION 8.3. Waiver of Past Defaults. The Holders of Certificates
evidencing not less than 51% of the Pool/Pre-Funding Balance (not including
Certificates held by the Seller, the Servicer or any of their respective
affiliates), with the written consent of the Insurer, may, on behalf of all
Certificateholders, waive any default by the Servicer in the performance of its
obligations hereunder and its consequences, except a default in the failure to
make any required deposits to or payments from the Collection Account in
accordance with this Agreement. Upon any such waiver of a past default, such
default shall cease to exist, and any Event of Default arising therefrom shall
be deemed to have been remedied for every purpose of this Agreement. No such
waiver shall extend to any subsequent or other default or impair any right
consequent thereon except to the extent expressly so waived. The Servicer shall
give prompt written notice of any waiver to the Rating Agencies and the Trustee.

         SECTION 8.4. Insurer Direction of Insolvency Proceedings. The Trustee,
upon the actual knowledge of a Responsible Officer of the Trustee, shall
promptly notify the Insurer of (i) the commencement of any of the events or
proceedings (individually, an "Insolvency Proceeding") described in Sections
8.1(d) or 8.1(e) hereof or any such event or proceeding applicable to an Obligor
under a Contract and (ii) the making of any claim in connection with any
Insolvency Proceeding seeking the avoidance as a preferential transfer (a
"Preference Claim") of any payment of principal of, or interest on, any Contract
or any Certificate. Each Certificateholder, by its purchase of Certificates, and
the Trustee hereby agree that, so long as neither a default under the Surety
Bond nor an Insurer Insolvency has occurred and is continuing, the Insurer may
at any time during the continuation of an Insolvency Proceeding direct all
matters relating to such Insolvency Proceeding, including, without limitation,
(i) all matters relating to any Preference Claim, (ii) the direction of any
appeal of any order relating to any Preference Claim and (iii) the posting of
any surety, or performance bond pending any such appeal. The Insurer shall be
subrogated to the rights of the Trustee and each Certificateholder in the
conduct of any Insolvency Proceeding, including, without limitation, all


                                       65
<PAGE>   70
rights of any party to an adversary proceeding action with respect to any court
order issued in connection with any such Insolvency Proceeding.


                                   ARTICLE IX

                                   The Trustee

         SECTION 9.1. No Power to Engage in Business or to Vary Investments.
Notwithstanding any provision or agreement to the contrary in this Agreement or
in any other agreement, the Trustee, acting on behalf of the Trust (but not
individually), shall not have any power to engage in any business, commercial or
other activity for profit, and the Trustee and the Servicer shall not have any
power to vary the Trust Estate, whether consisting of a Contract, an Eligible
Investment or any other amount (other than cash payments received with respect
to Contracts) in any account maintained for the benefit of the Trust or the
Certificateholders or Certificate Owners, by disposition of said property,
investment or amount and the reinvestment of the proceeds realized or by any
other action calculated to take advantage of any variation or change in the
market or in market conditions, for the purpose of improving the investment or
return of the Certificateholders or Certificate Owners.

         SECTION 9.2. Duties of Trustee. The Trustee, both prior to and after
the occurrence of an Event of Default, of which a Responsible Officer of the
Trustee has actual knowledge shall undertake to perform such duties and only
such duties as are specifically set forth in the Agreement. If an Event of
Default shall have occurred and shall not have been cured, the Trustee shall
exercise such of the rights and powers vested in it by the Agreement, and shall
use the same degree of care and skill in its exercise, as a prudent person would
exercise or use under the circumstance in the conduct of his own affairs.

         The Trustee, upon receipt of all resolutions, certificates, statements,
opinions, reports, documents, orders or other instruments furnished to the
Trustee that shall be specifically required to be furnished pursuant to any
provision of this Agreement, shall examine them to determine whether they comply
as to form to the requirements of this Agreement.

         No provision of this Agreement shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act (other than errors in judgment), or its own willful misconduct; provided,
however, that:

         (a) prior to the occurrence of an Event of Default, and after the
curing of all such Events of Default that may have occurred, the duties and
obligations of the Trustee shall be terminated solely by the express provisions
of this Agreement, the Trustee shall not be liable except for the performance of
such duties and obligations as shall be specifically set forth in this
Agreement, no implied covenants or obligations shall be read into this Agreement
against the Trustee and, in the absence of bad faith on the part of the Trustee,
the Trustee may conclusively rely on the truth of the statements and the
correctness of the opinions expressed upon any certificates or opinions
furnished to the Trustee and conforming to the requirements of this Agreement;


                                       66
<PAGE>   71
         (b) the Trustee shall not be liable for an error of judgment made in
good faith by a Responsible Officer or Responsible Officers of the Trustee,
unless it shall be proved that the Trustee shall have been negligent in
performing its duties in accordance with the terms of this Agreement; and

         (c) the Trustee shall not be liable with respect to any action taken,
suffered, or omitted to be taken by it in good faith in accordance with the
written direction of the Insurer or Holders of Certificates evidencing in the
aggregate not less than 25% of the Pool/Pre-Funding Balance relating to the
time, method, and place of conducting any proceeding for any remedy available to
the Trustee, or exercising any trust or power conferred upon the Trustee, under
this Agreement.

         The Trustee shall not be required to expend or risk its own funds or
otherwise incur financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers, if there shall be
reasonable ground for believing that the repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it, and
none of the provisions contained in this Agreement shall in any event require
the Trustee to perform or be responsible for the manner of performance of, any
of the obligations of the Servicer under this Agreement.

         The Trustee shall not be charged with knowledge of an Event of Default
or a failure by the Servicer to comply with any of its obligations unless and
until such time as a Responsible Officer shall have actual knowledge or have
received written notice thereof from the Servicer, the Insurer or any Holder of
Certificates evidencing in the aggregate not less than 10% of the
Pool/Pre-Funding Balance.

         In the event the entity acting as Trustee hereunder is also acting as
Yield Supplement Agent or Back-up Servicer, the rights and protections afforded
to the Trustee pursuant to this Article IX shall also be afforded to such Yield
Supplement Agent and Back-up Servicer.

         Except for actions expressly authorized by the Agreement or, based upon
an Opinion of Counsel, in the best interests of Certificateholders, the Trustee
shall take no action reasonably likely to impair the security interest of the
Trust in any Contract or to impair the value of any Contract.

         The Trustee shall not be liable for the selection of Eligible
Investments or for any investment losses resulting from Eligible Investments.

         The Trustee shall have no duty to monitor the performance of the
Servicer, nor shall it have any liability in connection with the malfeasance or
nonfeasance by the Servicer. The Trustee shall have no liability in connection
with compliance of the Servicer or the Seller with statutory or regulatory
requirements related to the Contracts. The Trustee shall not make or be deemed
to have made any representations or warranties with respect to the Contracts or
the validity or sufficiency of any assignment of the Contracts to the Trust or
the Trustee.

         All information obtained by the Trustee regarding the Obligors and the
Contracts, whether upon the exercise of its rights under the Agreement or
otherwise, shall be maintained by the Trustee in confidence, provided, however,
that the foregoing shall not be construed to prohibit (i) disclosure of any and
all information that is or becomes publicly known, or information obtained by
the Trustee from sources other than the Seller, Insurer, any Obligor or the
Servicer, (ii) disclosure of any and all information (A) if required to do so by
any applicable statute, law, rule or regulation, (B) to any government agency or
regulatory or self-regulatory body having or claiming authority to regulate or
oversee any aspects of the Trustee's business or that of its Affiliates, (C)
pursuant to any subpoena, civil investigative demand or similar demand or
request of any court, regulatory authority, arbitrator or arbitration to which
the Trustee or an Affiliate or an officer, director, employer or shareholder
thereof is a party, (D) in any preliminary or final offering circular,
registration statement or contract or other document pertaining to the
transactions contemplated by the Agreement approved in advance by the Seller or
(E) to any Affiliate, independent or internal auditor, agent, employee or
attorney of the Trustee having a need to know the same, provided that the
Trustee advises such recipient of the confidential nature of the information
being disclosed, (iii) any other disclosure authorized by the Seller or the
Servicer or (iv) disclosure to the other parties to the transactions
contemplated by the Agreement.

         In the event that the Paying Agent or the Transfer Agent and
Certificate Registrar shall fail to perform any obligation, duty or agreement in
the manner or on the day required to be performed by the Paying Agent or the
Transfer Agent and Certificate Registrar, as the case may be, under the
Agreement, the Trustee shall be obligated promptly upon a Responsible Officer
obtaining actual knowledge thereof to perform such obligation, duty or agreement
in the manner so required to the extent the information necessary to such
performance is reasonably available to the Trustee after the Trustee has made a
reasonable effort to obtain such information. The Trustee shall not be liable
for the acts or omissions of any Paying Agent, any Authenticating Agent or the
Transfer Agent and Certificate Registrar appointed hereunder with due care by
the Trustee hereunder.

         SECTION 9.3. Trustee's Assignment of Purchased Contracts. With respect
to all Contracts repurchased by the Seller pursuant to Section 2.3 or purchased
by the Servicer pursuant to Sections 3.7 or 10.2, the Trustee on behalf of the
Trust shall assign, without recourse, representation, or warranty to the Seller
or the Servicer, as the case may be, all the Trust's right, title, and interest
in and to such Contract, and all security and documents relating thereto. The
preparation of documents necessary to consummate such an assignment shall be the
responsibility of the Seller, the Servicer or the Insurer, as the case may be,
and not the responsibility of the Trustee. If in any enforcement suit or legal
proceeding it shall be held that the Servicer may not enforce a Contract on the
ground that it shall not be a real party in interest or a holder entitled to
enforce the Contract, the Trustee shall, at the Servicer's expense, take such
steps as directed in writing by the Servicer to enforce the Contract, including
bringing suit in the Trustee's name or the names of the Certificateholders,
provided that nothing in this Section 9.3 shall require the Trustee to qualify
to do business in a state in which it is not so qualified on the date of this
Agreement.

         SECTION 9.4. Certain Matters Affecting the Trustee. Except as otherwise
provided in Section 9.1:

         (a) the Trustee may conclusively rely and shall be fully protected in
acting or refraining from acting upon any resolution, Officer's Certificate,
certificate of auditors or any other certificate, statement, instrument,
opinion, report, notice, request, consent, order, appraisal, bond, note or other
paper or document believed by it to be genuine and to have been signed or
presented by the proper party or parties;

         (b) the Trustee may consult with counsel and any Opinion of Counsel or
any advice of such Counsel shall be full and complete authorization and
protection in respect of any action taken or suffered or omitted by it under
this Agreement in good faith and in accordance with such Opinion of Counsel or
advice. A copy of any such Opinion of Counsel shall be provided to the Seller,
the Servicer and the Insurer;

         (c) the Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Agreement, or to institute, conduct or
defend any litigation under this Agreement or in relation to this Agreement, at
the request, order or direction of any of the Certificateholders pursuant to the
provisions of this Agreement, unless such Certificateholders shall have offered
to the Trustee reasonable security or indemnity against the cost, expenses, and
liabilities that may be incurred therein or thereby. Nothing contained in this
Agreement, however, shall relieve the Trustee of the obligations, upon the
occurrence of an Event of Default (that shall not have been cured), to exercise
such of the rights and powers vested in it by this Agreement, and to use the
same degree of care and skill in their exercise as a prudent man would exercise
or use under the circumstances in the conduct of his own affairs; provided that
the Trustee shall not be deemed to have knowledge of the occurrence of an Event
of Default unless and until such knowledge shall be (i) actual knowledge of a
Responsible Officer or (ii) received in writing by a Responsible Officer;

         (d) the Trustee shall not be personally liable for any action taken,
suffered or omitted by it in good faith and believed by it to be authorized or
within the discretion or rights or powers conferred upon it by this Agreement;

         (e) prior to the occurrence of an Event of Default and after the curing
of all Events of Default that may have occurred, the Trustee shall not be bound
to make any investigation into the facts of matters stated in any resolution,
certificate, statement, instrument, opinion, report, notice, request, consent,
direction, order, approval, bond, note or other paper or document, unless
requested in writing to do so by the Insurer or Holders of Certificates
evidencing in the aggregate not less than 25% of the Pool/Pre-Funding Balance;
provided, however, that if the payment within a reasonable time to the Trustee
of the costs, expenses, or liabilities likely to be incurred by it in the making
of such investigation shall be, in the opinion of the Trustee, not reasonably
assured to the Trustee by the security afforded to it by the terms of this
Agreement, the Trustee may require reasonable indemnity against such cost,
expense, or liability as a condition to so proceeding. The reasonable expense of
any and every such examination shall be paid by the Seller or, if paid by the
Trustee, shall be reimbursed by the Seller upon demand. Nothing in this clause
(e) shall affect the obligation of the Seller to observe any applicable law


                                       69
<PAGE>   74
prohibiting disclosure of information regarding the Obligors; provided the
Trustee shall be entitled to make such further inquiry or investigation into
such facts or matters as it may reasonably see fit, and if the Trustee shall
determine to make such further inquiry or investigation, it shall be entitled to
examine the books and records of the Seller, personally or by agent or attorney,
at the sole cost and expense of the Seller;

         (f) the Trustee may execute any of the trust powers hereunder or
perform any duties under this Agreement either directly or by or through agents
or attorneys or a custodian or nominee and the Trustee shall not be responsible
for any misconduct or negligence on the part of, or for the supervision of any
such agent, attorney, custodian or nominee appointed with due care by it
hereunder;

         (g) the Trustee shall not be required to make any initial or periodic
examination of any documents or records related to the Contracts for the purpose
of establishing the presence or absence of defects, the compliance by the Seller
with its representations and warranties or for any other purpose; and

         (h) in the event that the Trustee is also acting as Custodian, Paying
Agent or Transfer Agent and Certificate Registrar hereunder, the rights and
protections afforded to the Trustee pursuant to this Article IX shall also be
afforded to such Custodian, Paying Agent, Transfer Agent and Certificate
Registrar.

         SECTION 9.5. Trustee Not Liable for Certificates or Contracts. The
Trustee shall make no representations as to the validity or sufficiency of this
Agreement or of the Certificates (other than its execution of Certificates on
behalf of the Trust and the certificate of authentication on the Certificates)
or of any Contract or related document. The Trustee shall at no time have any
responsibility or liability for or with respect to the legality, validity, and
enforceability of any security interest in any Financed Vehicle or any Contract,
or the perfection and priority of such a security interest or the maintenance of
any such perfection and priority, or for or with respect to the efficacy of the
Trust or its ability to generate the payments to be distributed to
Certificateholders under this Agreement, including: the existence, condition,
location, and ownership of any Financed Vehicle; the existence and
enforceability of any insurance policy thereon; the existence and contents of
any Contract or any computer or other record thereof; the validity of the
assignment of any Contract to the Trust or of any intervening assignment; the
completeness of any Contract; the performance or enforcement of any Contract;
the compliance by the Seller with any warranty or representation made under this
Agreement or in any related document and the accuracy of any such warranty or
representation prior to the Trustee's receipt of written notice of any
noncompliance therewith or any breach thereof; any investment of monies by the
Servicer or any loss resulting therefrom (it being understood that the Trustee
shall remain responsible for any Trust property that it may hold); the acts or
omissions of the Seller or any Obligor; an action of the Servicer taken in the
name of the Trustee; or any action by the Trustee taken at the instruction of
the Servicer; provided, however, that the foregoing shall not relieve the
Trustee of its obligation to perform its duties under this Agreement. Except
with respect to a claim based on the failure of the Trustee to perform its
duties under this Agreement or based on the Trustee's negligence or willful
misconduct in the performance of its duties hereunder, no recourse shall be had
for any claim based on any provision of this Agreement,


                                       70
<PAGE>   75
the Certificates, or any Contract or assignment thereof against the Trustee in
its individual capacity. The Trustee shall not have any personal obligation,
liability, or duty whatsoever to any Certificateholder or any other Person with
respect to any such claim, and any such claim shall be asserted solely against
the Trust or any indemnitor who shall furnish indemnity as provided in this
Agreement. The Trustee shall not be accountable for the use or application by
the Seller of any of the Certificates or of the proceeds of such Certificates,
or for the use or application of any funds paid to the Seller in respect of the
Contracts.

         SECTION 9.6. Trustee May Own Certificates. The Trustee in its
individual or any other capacity, and any of its Affiliates, may become the
owner or pledgee of Certificates with the same rights as it would have if it
were not Trustee, subject to the definition of the term "Certificateholder" in
Section 1.1.

         SECTION 9.7. Trustee's Fees and Expenses. The Servicer shall covenant
and agree to pay to the Trustee, and the Trustee shall be entitled to,
reasonable compensation (which shall not be limited by any provision of law in
regard to the compensation of a trustee of an express trust) for all services
rendered by it in the execution of the trusts created by this Agreement and in
the exercise and performance of any of the powers and duties under this
Agreement of the Trustee. Other than as included in the Trustee's compensation,
the Servicer shall pay or reimburse the Trustee upon its request for all
reasonable expenses (including, without limitation, expenses incurred in
connection with notices or other communications to Certificateholders),
disbursements, and advances (including the reasonable compensation and the
expenses and disbursements of its counsel and of all persons not regularly in
its employ) incurred or made by the Trustee in accordance with this Agreement or
in defense of any action brought against it in connection with this Agreement
except any such expense, disbursement, or advance as may arise from its
negligence (other than errors in judgment) or bad faith or that is the
responsibility of Certificateholders under this Agreement. Additionally, the
Seller, pursuant to Section 6.1, and the Servicer, pursuant to Section 7.1,
respectively, shall have agreed to indemnify the Trustee with respect to certain
matters, and certain Certificateholders, pursuant to Section 9.4, shall have
agreed to indemnify the Trustee under certain circumstances. Notwithstanding the
failure of the Servicer to perform any of its obligations under this Section ,
the Trustee shall continue to perform its obligations under this Agreement. The
Servicer's covenant to pay the expenses, disbursements and advances provided for
above shall survive the termination of this Agreement.

         SECTION 9.8. Indemnity of Trustee. The Trustee and its officers,
directors, agents and employees, shall be indemnified by the Servicer and held
harmless against any loss, liability, or expense (other than any amount owing
pursuant to Section 9.7) arising out of or incurred in connection with the
acceptance or performance of the trusts and duties contained in the Agreement
including the costs and expenses of defending against any claim or liability in
connection with the exercise or performance of any of its powers and duties
hereunder to the extent that (i) the Trustee shall not have been indemnified for
such loss, liability, or expense by the Seller pursuant to Section 6.1, the
Servicer pursuant to Section 7.1, or the Certificateholders pursuant to Section
9.4; (ii) such loss, liability, or expense shall not have been incurred by
reason of the Trustee's willful misfeasance, bad faith, or negligence (except
for errors in judgment); and (iii) such loss, liability, or expense shall not
have been incurred by reason of the Trustee's breach of its representations and
warranties pursuant to Section 9.14.


                                       71
<PAGE>   76
         SECTION 9.9. Eligibility Requirements for Trustee. The Trustee under
this Agreement shall at all times be a depository institution or trust company
organized and doing business under the laws of any state or the United States of
America; authorized under such laws to exercise corporate trust powers; and
having a combined capital and surplus of at least $50,000,000 and subject to
supervision or examination by federal or state authorities. If such depository
institution or trust company shall publish reports of condition at least
annually, pursuant to law or to the requirements of the aforesaid supervising or
examining authority, then for the purpose of this Section 9.9, the combined
capital and surplus of such depository institution or trust company shall be
deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. In case at any time the Trustee shall cease to
be eligible in accordance with the provisions of this Section 9.9, the Trustee
shall resign immediately in the manner and with the effect specified in Section
9.10.

         SECTION 9.10. Resignation or Removal of Trustee. The Trustee may at any
time resign and be discharged from the trusts hereby created by giving written
notice thereof to the Servicer. Upon receiving such notice of resignation, the
Servicer shall promptly appoint a successor Trustee acceptable to the Insurer by
written instrument, in duplicate, one copy of which instrument shall be
delivered to the resigning Trustee and one copy to the successor Trustee. If no
successor Trustee shall have been so appointed and have accepted appointment
within 30 days after the giving of such notice of resignation, the resigning
Trustee may petition any court of competent jurisdiction for the appointment of
a successor Trustee.

         If at any time the Trustee shall cease to be eligible in accordance
with the provisions of Section 9.9 and shall fail to resign after written
request therefor by the Servicer with the written consent of the Insurer, or if
at any time the Trustee shall be legally unable to act, or shall be adjudged a
bankrupt or insolvent, or a receiver of the Trustee or of its property shall be
appointed, or any public officer shall take charge or control of the Trustee or
of its property or affairs for the purpose of rehabilitation, conservation, or
liquidation, then the Servicer may, with the written consent of the Insurer,
remove the Trustee. If it shall remove the Trustee under the authority of the
immediately preceding sentence, the Servicer shall promptly appoint a successor
Trustee by written instrument, in duplicate, one copy of which instrument shall
be delivered to the Trustee so removed and one copy to the successor Trustee.

         If the Trustee is acting as Custodian, any resignation or removal of
the Trustee will result in the automatic termination of the Trustee's duties as
Custodian effective concurrently with such resignation or removal. Upon such
termination or removal, the Trustee shall, upon the request of the Servicer,
deliver the Contract Documents to the facilities of the successor Trustee.

         Any resignation or removal of the Trustee and appointment of a
successor Trustee pursuant to any of the provisions of this Section 9.10 shall
not become effective until acceptance of appointment by the successor Trustee
pursuant to Section 9.11.

         SECTION 9.11. Successor Trustee. Any successor Trustee appointed
pursuant to Section 9.10 shall execute, acknowledge, and deliver to the Servicer
and to its predecessor Trustee an instrument accepting such appointment under
this Agreement, and thereupon the resignation or removal of the predecessor
Trustee shall become effective and such successor


                                       72
<PAGE>   77
Trustee, without any further act, deed or conveyance, shall become fully vested
with all the rights, powers, duties, and obligations of its predecessor under
this Agreement, with like effect as if originally named as Trustee. The
predecessor Trustee shall deliver to the successor Trustee all documents and
statements held by it under this Agreement, or copies thereof, at the expense of
the Servicer; and the Servicer and the predecessor Trustee shall execute and
deliver such instruments and do such other things as may reasonably be required
for fully and certainly vesting and confirming in the successor Trustee all such
rights, powers, duties and obligations.

         No successor Trustee shall accept appointment as provided in this
Section 9.11 unless at the time of such acceptance such successor Trustee shall
be eligible pursuant to Section 9.9.

         Upon acceptance of appointment by a successor Trustee pursuant to this
Section 9.11, the Servicer shall mail notice of the successor of such Trustee
under this Agreement to all Holders of Certificates at their addresses as shown
in the Certificate Register. If the Servicer shall fail to mail such notice
within 10 days after acceptance of appointment by the successor Trustee, the
successor Trustee shall cause such notice to be mailed at the expense of the
Servicer.

         The respective obligations of the Seller and the Servicer described in
Sections 2.7, 3.14, 6.1, 7.1, 9.5, 9.7 and 9.8 shall survive the removal or
resignation of the Trustee as provided in this Agreement or the termination of
the Trust as provided in Section 10.1.

         No Trustee under this Agreement shall be liable for any action or
omission of any successor Trustee.

         SECTION 9.12. Merger or Consolidation of Trustee. Any corporation into
which the Trustee may be merged or converted or with which it may be
consolidated, or any corporation resulting from any merger, conversion or
consolidation to which the Trustee shall be a party, or any corporation
resulting from any merger, conversion or consolidation to which the Trustee
shall be a party, or any corporation succeeding to the business of the Trustee,
shall be the successor of the Trustee hereunder, provided such corporation shall
be eligible pursuant to Section 9.9, without the execution or filing of any
instrument or any further act on the part of any of the parties hereto, anything
herein to the contrary notwithstanding.

         SECTION 9.13. Appointment of Co-Trustee or Separate Trustee.
Notwithstanding any other provisions of this Agreement, at any time, for the
purpose of meeting any legal requirements of any jurisdiction in which any part
of the Trust or any Financed Vehicle may at the time be located, the Servicer
and the Trustee acting jointly shall have the power and shall execute and
deliver all instruments to appoint one or more Persons approved by the Trustee
to act as co-trustee, jointly with the Trustee, or separate trustee or separate
trustees, of all or any part of the Trust, and to vest in such Person, in such
capacity and for the benefit of the Certificateholders, such title to the Trust,
or any part thereof, and, subject to the other provisions of this Section 9.13,
such powers, duties, obligations, rights, and trusts as the Servicer and the
Trustee may consider necessary or desirable. If the Servicer shall not have
joined in such appointment within 15 days after the receipt by it of a written
request so to do, or in case an Event of Default shall have occurred and be
continuing, the Trustee alone shall


                                       73
<PAGE>   78
have the power to make such appointment. No co-trustee or separate trustee under
this Agreement shall be required to meet the terms of eligibility as a successor
trustee pursuant to Section 9.9 and no notice to Certificateholders of the
appointment of any co-trustee or separate trustee shall be required pursuant to
Section 9.11.

         Each and every separate trustee and co-trustee shall, to the extent
permitted by law, be appointed and act subject to the following provisions and
conditions:

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

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

                  (iii) the Servicer and the Trustee acting jointly, or the
         Trustee acting alone may at any time accept the resignation of or
         remove any separate trustee or co-trustee.

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

         Any separate trustee or co-trustee may at any time, appoint the
Trustee, its agent or attorney-in-fact with full power and authority, to the
extent not prohibited by law, to do any lawful act under or in respect of this
Agreement on its behalf and in its name. No such appointment shall affect the
obligations of the Trustee hereunder. If any separate trustee or co-trustee
shall die, become incapable of acting, resign or be removed, all of its estates,
properties, rights, remedies and trusts shall vest in and be exercised by the
Trustee, to the extent permitted by law, without the appointment of a new or
successor trustee.


                                       74
<PAGE>   79
         SECTION 9.14. Representations and Warranties of Trustee. The Trustee
hereby makes the following representations and warranties on which the Seller
and Certificateholders shall rely:

         (a) the Trustee is a New York banking corporation duly organized,
validly existing, and in good standing under the laws of New York;

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

         (c) the execution and delivery of the Agreement and the performance by
the Trustee of its obligations under the Agreement does not violate any
provision of the Articles of Association or Bylaws of the Trustee; and

         (d) the Agreement has been duly authorized, executed and delivered by
the Trustee and shall constitute the legal, valid, and binding agreement of the
Trustee, enforceable in accordance with its terms except that (i) such
enforcement may be subject to bankruptcy, insolvency, reorganization, moratorium
or similar laws now or hereafter in effect relating to creditors' rights
generally and (ii) the remedy of specific performance and injunctive and other
forms of equitable relief may be subject to certain equitable defenses and to
the discretion of the court before which any proceeding thereof may be brought.

         SECTION 9.15. Tax Returns. The Servicer shall prepare or shall cause to
be prepared any tax returns required to be filed by the Trust and furnish to
Certificateholders all information required by the Code or the regulations
thereunder and shall remit such returns to the Trustee for signature at least
five days before such returns are due to be filed. The Trustee, upon request,
will furnish the Servicer with all such information known to the Trustee as may
be reasonably required in connection with the preparation of all tax returns of
the Trust, and shall, upon request, execute such returns. In no event shall the
Trustee in its individual capacity be liable for any liabilities, costs or
expenses of the Trust, the Certificateholders, the Seller or the Servicer
arising under any tax law or regulation, including, without limitation, federal,
state or local income or excise taxes or any other tax imposed on or measured by
income (or any interest or penalty with respect thereto or arising from any
failure to comply therewith).

         SECTION 9.16. Trustee May Enforce Claims Without Possession of
Certificates. All rights of action and claims under the Agreement or the
Certificates may be prosecuted and enforced by the Trustee without the
possession of any of the Certificates or the production thereof in any
proceeding relating thereto, and any such proceeding instituted by the Trustee
shall be brought in its own name or in its capacity as Trustee. Any recovery of
judgment shall, after provision for the payment of the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, be
for the ratable benefit of the Certificateholders in respect of which such
judgment has been recovered.

         SECTION 9.17. Suits for Enforcement. In case an Event of Default or
other default by the Servicer or the Seller hereunder shall occur and be
continuing, the Trustee, in its


                                       75
<PAGE>   80
discretion, may proceed to protect and enforce its rights and the rights of the
Certificateholders under the Agreement by a suit, action or proceeding in equity
or at law or otherwise whether for the specific performance of any covenant or
agreement contained in the Agreement or in aid of the execution of any power
granted in the Agreement or the enforcement of any other legal, equitable or
other remedy, as the Trustee, being advised by counsel, shall deem most
effectual to protect and enforce any of the rights of the Trustee or the
Certificateholders.

         SECTION 9.18. Maintenance of Office or Agency. The Trustee shall
maintain at its expense in New York, New York, an office or offices or agency or
agencies where notices and demands to or upon the Trustee in respect of the
Certificates and this Agreement may be served. The Trustee initially designates
the Corporate Trust Office as its office for such purposes. The Trustee will
give prompt written notice to the Servicer, the Paying Agent, the Transfer Agent
and Certificate Registrar, the Insurer and to Certificateholders of any change
in the location of such office or agency.


                                    ARTICLE X

                                   Termination

         SECTION 10.1. Termination of the Trust. The respective obligations and
responsibilities of the Seller, the Servicer and the Trustee created hereby and
the Trust created by this Agreement shall terminate upon the earlier of (i) the
maturity or other liquidation of the last Contract and the disposition of any
amounts received upon liquidation of any remaining Contracts in the Trust
(including the purchase of the Contracts by the Servicer pursuant to Section
10.2); (ii) (a) the payment to Certificateholders of all amounts required to be
paid to them pursuant to this Agreement and the disposition of all property held
as part of the Trust, (b) termination of the Surety Bond in accordance with its
terms and surrender of the Surety Bond to the Insurer for cancellation, (c) the
payment of all amounts owed to the Trustee under this Agreement and (d) the
payment of all amounts owed to the Insurer under the Insurance Agreement,
provided, however, that in no event shall the trust created by the Agreement
continue beyond the expiration of 21 years from the death of the survivor of the
descendants, living on the date of this Agreement, of Joseph P. Kennedy,
formerly United States representative at the Court of St. James. The Servicer
shall promptly notify the Trustee and the Insurer of any respective termination
pursuant to this Section 10.1.

         Notice of any termination, specifying the Distribution Date upon which
the Certificateholders may surrender their Certificates to the Trustee for
payment of the final distribution and cancellation, shall be given promptly by
the Trustee by letter to Certificateholders mailed not later than the 10th day
prior to the specified Distribution Date and not earlier than the 15th day of
the month prior to the month of the specified Distribution Date stating the
amount of any such final payment, and that the Record Date otherwise applicable
to such Distribution Date is not applicable, payments being made only upon
presentation and surrender of the Certificates at the office or agency of the
Trustee therein specified. The Trustee shall give such notice to the Certificate
Registrar at the time such notice is given to Certificateholders. Upon
presentation and surrender of the Certificates, the Trustee shall cause


                                       76
<PAGE>   81
to be distributed to Certificateholders amounts distributable on such
Distribution Date pursuant to Section 4.3.

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

         Notwithstanding any provision to the contrary, the Trustee shall retain
all of its rights and powers and obligations and duties under Section 8.5 in the
event of any Insolvency Proceeding and the Trustee shall be entitled to all the
protections, rights and immunities provided in Article IX in connection with any
such Insolvency Proceeding.

         SECTION 10.2. Optional Purchase of All Contracts. On each Distribution
Date as of which the Pool Factor (after giving effect to the Principal
Distribution for such Distribution Date) shall be less than .100000, the
Servicer shall have the option to purchase the corpus of the Trust at a price
equal to the Repurchase Amount plus all amounts due and owing to the Insurer
under the Insurance Agreement. To exercise such option, the Servicer shall pay
to the Trustee by deposit into the Collection Account: (1) for the benefit of
the Certificateholders, the Repurchase Amount of all Contracts that were
Outstanding at the beginning of the Collection Period ending immediately prior
to such Distribution Date, and (2) for the benefit of the Insurer, all amounts
due and owing to the Insurer pursuant to the Insurance Agreement. Such purchase
shall be deemed to have occurred on the last day of such Collection Period.

                            Miscellaneous Provisions

         SECTION 11.1. Amendment. This Agreement may be amended by the Seller,
the Servicer and the Trustee, collectively with the prior written consent of the
Insurer, but without the consent of any of the Certificateholders, to cure any
ambiguity, to correct or supplement any provisions in the Agreement, or to add
any other provisions with respect to matters or questions arising under this
Agreement that shall not be inconsistent with the provisions of this Agreement;
provided, however, that such action shall not, as evidenced by an Opinion of
Counsel, adversely affect in any material respect the interests of any
Certificateholder or the Insurer.

         This Agreement may also be amended from time to time by the Seller, the
Servicer and the Trustee with the consent of the Holders of Certificates
evidencing in the aggregate not less


                                       77
<PAGE>   82
than 51% of the Pool/Pre-Funding Balance and the Insurer for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of the Agreement, or of modifying in any manner the rights of the
Holders of Certificates; provided, however, that no such amendment shall (i)
increase or reduce in any manner the amount of, or accelerate or delay the
timing of, collections of payments on Contracts or distributions that shall be
required to be made on any Certificate or (ii) reduce the aforesaid percentage
required to consent to any such amendment, without the consent of the Holders of
all Certificates then outstanding.

         Promptly after the execution of any such amendment or consent pursuant
to the next preceding paragraph, the Trustee shall furnish written notification
of the substance of such amendment or consent to each Certificateholder.

         It shall not be necessary for the consent of Certificateholders
pursuant to this Section 11.1 to approve the particular form of any proposed
amendment or consent, but it shall be sufficient if such consent shall approve
the substance thereof. The manner of obtaining such consents and of evidencing
the authorization of the execution thereof by Certificateholders shall be
subject to such reasonable requirements as the Trustee may prescribe.

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

         SECTION 11.2.      Protection of Title to Trust.

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

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

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


                                       78
<PAGE>   83
         (d) The Servicer shall maintain or cause to be maintained accounts and
records as to each Contract accurately and in sufficient detail to permit (i)
the reader thereof to know at any time the status of such Contract, including
payments and recoveries made and payments owing (and the nature of each) and
(ii) reconciliation between payments or recoveries on (or with respect to) each
Contract and the amounts from time to time deposited in or credited to the
Certificate Amount and Payahead Account in respect of such Contract.

         (e) The Servicer shall maintain or cause to be maintained its computer
systems so that, from and after the time of sale under the Agreement of the
Contracts to the Trust, the Servicer's master computer records (including any
back-up archives) that shall refer to a Contract indicate clearly that such
Contract is owned by the Trustee as trustee of the Trust. Indication of the
Trustee's ownership of a Contract shall be deleted from or modified on the
Servicer's computer systems when, and only when, the Contract shall have been
paid in full or repurchased or shall have become a Liquidated Contract.

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

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

         (h) Upon request, the Servicer shall furnish to the Trustee and the
Insurer, within five Business Days, a list of all Contracts then held as part of
the Trust, together with a reconciliation of such list to the Schedule of
Contracts and to each of the Servicer's Certificates furnished before such
request indicating removal of Contracts from the Trust.

         (i)      The Servicer shall deliver to the Trustee and the Insurer:

                  (i) promptly after the execution and delivery of this
         Agreement and of each amendment hereto and on each Subsequent Closing
         Date, an Opinion of Counsel either (A) stating that, in the opinion of
         such Counsel, all financing statements and continuation statements have
         been executed and filed that are necessary fully to preserve and
         protect the interest of the Trustee and the Insurer in the Contracts,
         and reciting the details of such filings or referring to prior Opinions
         of Counsel in which such details are given or (B) stating that, in the
         opinion of such Counsel, no such action shall be necessary to preserve
         and protect such interest; and

                  (ii) within 90 days after the beginning of each calendar year
         beginning with the first calendar year beginning more than three months
         after the Cut-Off Date an Opinion of Counsel, dated as of a date during
         such 90-day period, either (A) stating that,


                                       79
<PAGE>   84
         in the opinion of such counsel, all financing statements and
         continuation statements have been executed and filed that are necessary
         fully to preserve and protect the interest of the Trustee in the
         Contracts, and reciting the details of such filings or referring to
         prior Opinions of Counsel in which such details are given or (B)
         stating that, in the opinion of such counsel, no such action shall be
         necessary to preserve and protect such interest.

         (j) The Seller shall, to the extent required by applicable law, cause
the Certificates to be registered with the Securities and Exchange Commission
pursuant to Section 12(b) or Section 12(g) of the Securities Exchange Act of
1934 within the time periods specified in such sections.

         (k) For the purpose of facilitating the execution of this Agreement and
for other purposes, this Agreement may be executed simultaneously in any number
of counterparts, each of which counterpart shall be deemed to be an original,
and all of which counterparts shall constitute but one and the same instrument.

         SECTION 11.3. Limitation on Rights of Certificateholders. The death or
incapacity of any Certificateholder shall not operate to terminate the Agreement
or the Trust, nor entitle such Certificateholder's legal representatives or
heirs to claim an accounting or to take any action or commence any proceeding in
any court for a partition or winding up of the Trust, nor otherwise affect the
rights, obligations, and liabilities of the parties to the Agreement or any of
them.

         Except as expressly provided herein, no Certificateholder shall have
any right to vote or in any manner otherwise control the operation and
management of the Trust, or the obligations of the parties to this Agreement,
nor shall anything in this Agreement set forth, or contained in the terms of the
Certificates, be construed so as to constitute the Certificateholders from time
to time as partners or members of an association; nor shall any
Certificateholder be under any liability to any third person by reason of any
action taken pursuant to any provision of this Agreement.

         No Certificateholder shall have any right by virtue or by availing
itself of any provisions of this Agreement to institute any suit, action, or
proceeding in equity or at law upon or under or with respect to this Agreement,
unless such Holder previously shall have given to the Trustee a written notice
of default and of the continuance thereof, as hereinbefore provided, and unless
also the Holders of Certificates evidencing in the aggregate not less than 25%
of the Pool/Pre-Funding Balance with the consent of the Insurer shall have made
written request upon the Trustee to institute such action, suit or proceeding in
its own name as Trustee under this Agreement and shall have offered to the
Trustee such reasonable indemnity as it may require against the costs, expenses,
and liabilities to be incurred therein or thereby, and the Trustee, for 30 days
after its receipt of such notice, request, and offer of indemnity, shall have
neglected or refused to institute any such action, suit or proceeding; no one or
more Holders of Certificates shall have any right in any manner whatever by
virtue or by availing itself or themselves of any provisions of this Agreement
to affect, disturb, or prejudice the rights of the Holders of any other of the
Certificates, or to obtain or seek to obtain priority over or preference to any
other such Holders, or to enforce any right, under this Agreement, except in the
manner in the Agreement provided in the Agreement and for the equal, ratable,
and common benefit of all


                                       80
<PAGE>   85
Certificateholders. For the protection and enforcement of the provisions of this
Section 11.3, each Certificateholder and the Trustee shall be entitled to such
relief as can be given either at law or in equity.

mailed within the time prescribed in this Agreement shall be conclusively
presumed to have been duly given, whether or not the Certificateholder shall
receive such notice.

         SECTION 11.6. Severability of Provisions. If any one or more of the
covenants, agreements, provisions, or terms of this Agreement shall be for any
reason whatsoever held invalid, then such covenants, agreements, provisions, or
terms shall be deemed severable from the remaining covenants, agreements,
provisions, or terms of this Agreement and shall in no way affect the validity
or enforceability of the other provisions of this Agreement or of the
Certificates or the rights of the Holders thereof.

         SECTION 11.7. Assignment. Notwithstanding anything to the contrary
contained herein, except as provided in Sections 6.2 and 7.2, neither the Seller
nor the Servicer may transfer or assign all, or a portion of, its rights,
obligations and duties under the Agreement unless such transfer or assignment
(i) (A) will not result in a reduction or withdrawal by Standard & Poor's or
Moody's of the rating then assigned to the Certificates and (B) the Trustee and
the Insurer have consented to such transfer or assignment, or (ii) the Insurer,
the Trustee and Holders of Certificates evidencing not less than 51% of the

duties and obligations under the Agreement. In the event of a transfer or
assignment pursuant to clause (ii) above, the Rating Agencies shall be provided
with notice of such transfer or assignment.

         SECTION 11.8. Certificates Nonassessable and Fully Paid.

                                       81
<PAGE>   86
upon authentication thereof by the Trustee pursuant to Section 5.2, Certificates
shall be deemed fully paid.

         SECTION 11.9. Third Party Beneficiaries. Except as otherwise
specifically provided herein with respect to the Certificateholders, the parties
to this Agreement hereby manifest their intent that no third party other than
the Insurer shall be deemed a third party beneficiary of this Agreement, and
specifically that the Obligors are not third party beneficiaries of this
Agreement.

         SECTION 11.10. Insurer Default or Insolvency. If a default under the
Surety Bond has occurred and is continuing or an Insurer Insolvency has
occurred, any provision giving the Insurer the right to direct, appoint or
consent to, approve of, or take any action (or waive any right to take action)
under this Agreement, shall be inoperative during the period of such default or
the period from and after such Insurer Insolvency and such consent or approval
shall be deemed to have been given for the purpose of such provisions; provided
that the consent of the Insurer shall be required at all times with respect to
any amendment of this Agreement pursuant to Section 11.1.

         SECTION 11.11. Tax Matters. The parties hereto intend that the Trust
shall be a grantor trust for federal and state income tax purposes and not as an
association taxable as a corporation. All provisions of this Agreement shall be
construed so as to effectuate such intent.

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

from claims under certain insurance policies in respect of individual Subsequent
Financed Vehicles or the related Obligors.

                  Under the Agreement, there will be a monthly pro rata
distribution to the Certificateholders of record on the 15th day of each month
or, if such 15th day is not a Business Day, the next succeeding Business Day
(the "Distribution Date"), commencing on January 15, 1997, of such
Certificateholder's fractional undivided interest in all amounts allocable to
principal and interest from any applicable source described in the Agreement.
The monthly interest on each given Distribution Date shall be the product of
one-twelfth the Pass-Through Rate and the Pool/Pre-Funding Balance as of the end
of the immediately preceding Collection Period (or if the current Distribution
Date is the first Distribution Date as of the Closing Date) plus the amount of
interest previously due but not paid to Certificateholders, if any. The monthly
principal on each given Distribution Date shall be the sum of the Aggregate
Scheduled Balance Decline during the related Collection Period and, with respect
to the Final Funding Period Distribution Date, the Prepayment Amount. The
distribution is more fully described in the Agreement.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the Certificateholder of record in the Certificate Register
without the presentation or surrender of this Certificate or the making of any
notation hereon. Except as otherwise provided in the Agreement and
notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee of the pendency of such distribution and
only upon presentation and surrender of this Certificate at the office or agency
maintained for that purpose by the Trustee and Certificate Registrar in the
Borough of Manhattan, the City of New York.

                            [REVERSE OF CERTIFICATE]

                  The Certificates do not represent an obligation of, or an
interest in, the Seller, the Servicer, the Trustee or any affiliate of any of
them. The Certificates are limited in right of payment to certain collections
and recoveries respecting the Contracts and payments under the Surety Bond, all
as more specifically set forth herein and in the Agreement. A copy of the
Agreement may be examined by any Certificateholder upon request during normal
business hours at the corporate administrative offices of the Seller currently
located at 8001 Irvine Center Drive, 5th Floor, Irvine, California 92618 and at
such other places, if any, designated by the Seller.

                  The Agreement permits, with certain exceptions therein
provided, the amendment and the modification of the rights and obligations of
the Seller and the Servicer and the rights of the Certificateholders under the
Agreement at any time by the Seller, the Servicer and the Trustee with the
consent of the Holders of Certificates evidencing in the aggregate not less than
51% of the Pool/Pre-Funding Balance and the Insurer provided, however, that no
such amendment shall (a) increase or reduce in any manner the amount of, or
accelerate or delay the timing of, collections of payments on Contracts or
distributions that shall be required to be made on any Certificate or (b) reduce
the aforesaid percentage required to consent to any such amendment, without the
consent of the Holders of all Certificates then outstanding. Any such consent by
the Holder of this Certificate shall be conclusive and binding on such Holder
and upon all future Holders of this Certificate and of any Certificate issued
upon the transfer hereof or in exchange hereof or in lieu hereof whether or not
notation of such consent is made upon this Certificate. The Agreement also
permits the amendment thereof, in certain limited circumstances, without the
consent of the Holder of any of the Certificates.

                  As provided in the Agreement, the transfer of this Certificate
is registrable in the Certificate Register upon surrender of this Certificate
for registration of transfer at the offices or agencies maintained by the
Trustee in its capacity as Certificate Registrar, or by any successor
Certificate Registrar, in the Borough of Manhattan, the City of New York,
accompanied by a written instrument of transfer in form satisfactory to the
Trustee and the Certificate Registrar duly executed by the Holder hereof or such
Holder's attorney duly authorized in writing, and thereupon one or more new
Certificates of authorized denominations evidencing the same aggregate interest
in the Trust will be issued to the designated transferee.

                  The Certificates are issuable only as registered Certificates
without coupons in denominations of $1,000 and integral multiples thereof. As
provided in the Agreement, Certificates are exchangeable for new Certificates of
authorized denominations evidencing the same aggregate denomination, as
requested by the Holder surrendering the same.

                  No service charge will be made for any such registration of
transfer or exchange, but the Trustee may require payment of a sum sufficient to
cover any tax or governmental charge payable in connection therewith.

                  The Trustee, the Certificate Registrar, and any agent of the
Trustee or the Certificate Registrar may treat the person in whose name this
Certificate is registered as the


                                       B-4
<PAGE>   94
owner hereof for all purposes, and neither the Trustee, the Certificate
Registrar, nor any such agent shall be affected by any notice to the contrary.

                  The obligations and responsibilities created by the Agreement
and the Trust created thereby shall terminate upon the earlier of (i) the
maturity or other liquidation of the last Contract (including pursuant to the
Servicer's option to purchase the Contracts) and the disposition of any amounts
received upon liquidation of any remaining Contracts in the Trust and (ii) (a)
the payment to Certificateholders of all amounts required to be paid to them
pursuant to the Agreement and the disposition of all property held as part of
the Trust, (b) termination of the Surety Bond in accordance with its terms and
the surrender of the Surety Bond to the Insurer for cancellation, (c) the
payment of all amounts owed to the Trustee under the Agreement and (d) the
payment of all amounts owed to the Insurer under the Insurance Agreement. The
Servicer's exercise of its right to purchase all the Contracts and other
property of the Trust will effect early retirement of the Certificates; however,
such right of purchase is exercisable only as of a Distribution Date as of which
the Pool Factor was less then .100000.

         CAPITAL MARKETS ASSURANCE CORPORATION ("CapMAC"), for consideration
received, hereby unconditionally and irrevocably guarantees to the Trustee,
subject only to the terms of this Principal/Interest Surety Bond (the "Surety
Bond"), payment of the Insured Obligation. CapMAC agrees to pay (a) to the
Trustee, in respect of each Distribution Date, an amount equal to the amount, if
any, by which the sum of (i) the Interest Distribution for such Distribution
Date, (ii) the Principal Distribution for such Distribution Date and (iii) the
Servicing Fee for such Distribution Date exceeds the Collection Account Amount
Available for such Distribution Date and (b) on behalf of the Trustee, an amount
equal to any Avoided Payment;

provided, however, that no payment (other than any payment made in respect of
Avoided Payments) under this Surety Bond with respect to any Distribution Date
shall exceed the Surety Bond Amount for such Distribution Date.

      Capitalized terms used herein and not otherwise defined herein shall have
the meanings assigned to them in the Pooling and Servicing Agreement dated as of
December 1, 1996 among Onyx Acceptance Financial Corporation, as seller (the
"Seller"), Onyx Acceptance Corporation, as servicer (the "Servicer") and the
Trustee (the "Pooling and Servicing Agreement").

      As used herein the term "Certificate Balance" means the aggregate
principal balances of the Certificates then outstanding.


                                       C-1
<PAGE>   96
      As used herein the term "Insolvency Proceeding" means the commencement,
after the date hereof, of any bankruptcy, insolvency, readjustment of debt,
reorganization, marshalling of assets and liabilities or similar proceedings by
or against the Seller or Servicer, the commencement, after the date hereof, of
any proceedings by or against the Seller or Servicer for the winding up or
liquidation of its affairs, or the consent, after the date hereof, to the
appointment of a trustee, conservator, receiver or liquidator in any bankruptcy,
insolvency, readjustment of debt, reorganization, marshalling of assets and
liabilities or similar proceedings of or relating to the Seller or Servicer.

      As used herein the term "Servicing Fee" means, as to any Distribution
Date, the fee payable to the Servicer for services rendered during the
Collection Period ending immediately prior to such Distribution Date, which
shall equal with respect to each Contract, the product of (A) the Servicing Fee
Percent and (B) the Scheduled Balance of such Contract as of the close of the
preceding Collection Period.

      As used herein the term "Surety Bond Amount" means, the sum of (a) in the
case of the first Distribution Date, the initial Certificate Balance, or in the
case of any Distribution Date thereafter, the Certificate Balance on the
immediately preceding Distribution Date (after giving effect to the Principal
Distribution on such preceding Distribution Date), (b) the Interest Distribution
payable on such Distribution Date and (c) the Servicing Fee payable on such
Distribution Date.

      Payment of amounts hereunder shall be made in immediately available funds
on the later of (a) 11:00 a.m., New York City time, on the Business Day
immediately preceding a Distribution Date and (b) 11:00 a.m., New York City
time, on the Business Day next succeeding presentation to CapMAC (as hereinafter
provided) of a notice for payment in the form of Exhibit A hereto ("Notice for
Payment"), appropriately completed and executed by the Trustee. A Notice for
Payment under this Surety Bond may be presented to CapMAC on any Business Day
following the Servicer Report Date in respect of which the Notice for Payment is
being presented, by (a) delivery of the original Notice for Payment to CapMAC at
its address set forth below, or (b) facsimile transmission of the original
Notice for Payment to CapMAC at its facsimile number set forth below. If
presentation is made by facsimile transmission, the Trustee shall (i)
simultaneously confirm transmission by telephone to CapMAC at its telephone
number set forth below, and (ii) as soon as reasonably practicable, deliver the
original Notice for Payment to CapMAC at its address set forth below. Any Notice
for Payment received by CapMAC after 1:00 p.m., New York City time, on a
Business Day, or on any day that is not a Business Day, will be deemed to be
received by CapMAC at 9:00 a.m., New York City time, on the next succeeding
Business Day.

      Subject to the foregoing, if the payment of any amount with respect to the
Insured Obligation is voided (a "Preference Event") under any applicable
bankruptcy, insolvency, receivership or similar law in an Insolvency Proceeding,
and as a result of such Preference Event, any Certificateholder is required to
return such voided payment, or any portion of such voided payment, made in
respect of any Certificate (an "Avoided Payment"), CapMAC will pay an amount
equal to such Avoided Payment, irrevocably, absolutely and


                                       C-2
<PAGE>   97
unconditionally and without the assertion of any defenses to payment, including
fraud in inducement or fact or any other circumstances that would have the
effect of discharging a surety in law or in equity, upon payment of such
Certificateholder of such Avoided Payment and receipt by CapMAC from the Trustee
on behalf of such Certificateholder of (x) a certified copy of a final order of
a court exercising jurisdiction in such Insolvency Proceeding to the effect that
the Certificateholder is required to return any such payment or portion thereof
prior to the Termination Date of this Surety Bond because such payment was
voided under applicable law, with respect to which order the appeal period has
expired without an appeal having been filed (the "Final Order"), (y) an
assignment, substantially in the form attached hereto as Exhibit B, properly
completed and executed by such Certificateholder irrevocably assigning to CapMAC
all rights and claims of such Certificateholder relating to or arising under
such Avoided Payment, and (z) a Notice for Payment in the form of Exhibit A
hereto appropriately completed and executed by the Trustee.

      CapMAC shall make payments due in respect of Avoided Payments prior to
1:00 p.m. New York City time on the second Business Day following CapMAC's
receipt of the documents required under clauses (x) through (z) of the preceding
paragraph. Any such documents received by CapMAC after 3:00 p.m. New York City
time on any Business Day or on any day that is not a Business Day shall be
deemed to have been received by CapMAC prior to 3:00 p.m. on the next succeeding
Business Day. All payments made by CapMAC hereunder on account of any Avoided
Payment shall be made to the Trustee for the benefit of the Certificateholder
entitled to such payment.

      CapMAC hereby waives and agrees not to assert any and all rights to
require the Trustee to make demand on or to proceed against any person, party or
security prior to the Trustee demanding payment under this Surety Bond.

      No defenses, set-offs and counterclaims of any kind available to CapMAC so
as to deny payment of any amount due in respect of this Surety Bond will be
valid and CapMAC hereby waives and agrees not to assert any and all such
defenses, set-offs and counterclaims, including, without limitation, any such
rights acquired by subrogation, assignment or otherwise. Any rights of
subrogation acquired by CapMAC as a result of any payment made under this Surety
Bond shall, in all respects, be subordinate and junior in right of payment to
the prior indefeasible payment in full of all amounts due the Trustee on account
of payments due under the Certificates.

      This Surety Bond is neither transferable nor assignable, in whole or in
part, except to a successor trustee duly appointed and qualified under the
Pooling and Servicing Agreement. All notices, presentations, transmissions,
deliveries and communications made by the Trustee to CapMAC with respect to this
Surety Bond shall specifically refer to the number of this Surety Bond and shall
be made to CapMAC at:

or such other address, telephone number or facsimile number as CapMAC may
designate to the Trustee in writing from time to time. Each such notice,
presentation, transmission, delivery and communication shall be effective only
upon actual receipt by CapMAC.

      The obligations of CapMAC under this Surety Bond are irrevocable, primary,
absolute and unconditional (except as expressly provided herein) and neither the
failure of the Trustee, the Seller, the Servicer or any other person to perform
any covenant or obligation in favor of CapMAC (or otherwise), nor the failure or
omission to make a demand permitted hereunder, nor the commencement of any
bankruptcy, debtor or other insolvency proceeding by or against the Trustee, the
Seller, the Servicer or any other person shall in any way affect or limit
CapMAC's obligations under this Surety Bond. If a successful action or
proceeding to enforce this Surety Bond is brought by the Trustee, the Trustee
shall be entitled to recover from CapMAC costs and expenses reasonably incurred,
including without limitation reasonable fees and expenses of counsel.

      There shall be no acceleration payment due under this Surety Bond unless
such acceleration is at the sole option of CapMAC.

      This Surety Bond and the obligations of CapMAC hereunder shall terminate
on the date (the "Termination Date") that is one year and one day following the
earlier of (a) the Final Distribution Date and (b) the date on which all amounts
required to be paid to the Certificateholders have been paid in full, provided,
that, if an Insolvency Proceeding is existing by or against the Seller or the
Servicer during such one year and one day period, then this Surety Bond and
CapMAC's obligations hereunder shall terminate on the date of the conclusion or
dismissal of such Insolvency Proceeding without continuing jurisdiction by the
court in such Insolvency Proceeding, provided, further that, and notwithstanding
anything herein to the contrary, this Surety Bond shall not terminate prior to
the date on which CapMAC has made all payments required to be made under the
terms of this Surety Bond in respect of such Avoided Payments.

      Upon any payment hereunder, in furtherance and not in limitation of
CapMAC's equitable right of subrogation and CapMAC's rights under the Insurance
Agreement, CapMAC will be subrogated to the rights of the Certificateholder in
respect of which such payment was made to receive any and all amounts due in
respect of the obligations in respect of which CapMAC has made a payment
hereunder.

      All payments made hereunder by CapMAC shall be made with CapMAC's own
funds. The payment by the Trust or CapMAC to the Trustee of any amount
guaranteed by the first paragraph of this Surety Bond, and the payment by CapMAC
of any Avoided Payment after


                                       C-4
<PAGE>   99
the occurrence of a Preference Event shall constitute "payments" for all
purposes under this Surety Bond. In no event shall any payment be made under
this Surety Bond on account of (a) the failure of the Trustee to deliver the
proceeds of any such payment to any Certificateholder or (b) the failure of any
such Certificateholder to claim any such proceeds from the Trustee.

      This Surety Bond is not covered by the property/casualty insurance fund
specified in Article Seventy-Six of the New York State insurance law.

      This Surety Bond sets forth in full the undertaking of CapMAC, and shall
not, except with the prior written consent of the Trustee or otherwise in
accordance with the express terms hereof, be modified, altered or affected by
any other agreement or instrument, including any modification or amendment
thereto and may not be canceled or revoked by CapMAC prior to the Termination
Date.

      This Surety Bond shall be returned to CapMAC by the Trustee on the
Termination Date.


      THIS SURETY BOND SHALL BE CONSTRUED, AND THE OBLIGATIONS, RIGHTS AND
REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED, IN ACCORDANCE WITH THE
LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES OR
THE APPLICATION OF THE LAWS OF ANY OTHER JURISDICTION.


IN WITNESS WHEREOF, CapMAC has caused this Surety Bond to be executed on the
date first written above.

Ladies and Gentlemen:

                 At your request, we have examined the Registration Statement on
Form S-1 (Registration No. 333-16601) filed by you on behalf of the Onyx
Acceptance Grantor Trust 1996-4 (the "Trust") with the Securities and Exchange
Commission on November 22, 1996 and Amendment No. 1 thereto transmitted for
filing on December 10, 1996 (collectively, the "Registration Statement") in
connection with the registration under the Securities Act of 1933, as amended,
of Automobile Loan Pass-Through Certificates (the "Certificates"). The
Certificates are to be issued pursuant to a Pooling and Servicing Agreement
relating to the formation of the Trust and the issuance of the Certificates (the
"Pooling and Servicing Agreement") among Onyx Acceptance Financial Corporation
(the "Company"), Onyx Acceptance Corporation ("Servicer"), and Bankers Trust
Company (the "Trustee").

                 The Certificates are to be sold to the Underwriter as described
in the Registration Statement for resale to the public. As your counsel in
connection with this transaction, we have examined the proceedings taken and are
familiar with the proceedings proposed to be taken by you in connection with the
sale and issuance of the Certificates.

                 It is our opinion that, upon (i) conclusion of the proceedings
being taken or contemplated by us, as your counsel, to be taken prior to the
issuance of the Certificates, (ii) due execution and authentication of the
Certificates by the Trustee in accordance with the terms of the Pooling and
Servicing Agreement, and (iii) issuance and delivery of the Certificates against
payment therefor by the Underwriter in the manner described in the Registration
Statement, the Certificates will be legally issued, fully paid and
nonassessable.

          Re:      Onyx Acceptance Grantor Trust 1996-4:
                   Certain Federal Income Tax Issues

Ladies and Gentlemen:

                  We have acted as tax counsel to Onyx Acceptance Financial
Corporation (the "Company") in connection with the preparation of the Company's
Registration Statement on Form S-1 (Registration No. 333-16601) filed by the
Company on behalf of the Onyx Acceptance Grantor Trust 1996-4 (the "Trust") with
the Securities and Exchange Commission on November 22, 1996 and Amendment No. 1
thereto transmitted for filing on December 10, 1996 (collectively, the
"Registration Statement") in connection with the registration under the
Securities Act of 1933, as amended, of Automobile Loan Pass-Through Certificates
(the "Certificates"). The Certificates are to be issued pursuant to a Pooling
and Servicing Agreement relating to the formation of the Trust and the issuance
of the Certificates (the "Pooling and Servicing Agreement") among the Company,
Onyx Acceptance Corporation ("Servicer"), and Bankers Trust Company (the
"Trustee"). Capitalized terms used herein that are not otherwise defined have
the meaning assigned to such terms in the Registration Statement.

                  In rendering the opinions set forth below, we have examined
forms of the following documents presented to us and are relying (without any
independent investigation thereof) upon the truth and accuracy of the
statements, covenants, representations and warranties set forth therein:

                  1.       The Registration Statement;

                  2.       The Pooling and Servicing Agreement;

                  3.       The Purchase Agreement;

                  4.       The Yield Supplement Agreement; and

                  5.       Such other agreements and documents as we have
                           considered necessary or appropriate for the purpose
                           of rendering the opinions set forth below.

                  In rendering the opinions set forth below, we have relied upon
the following representations and assumptions:

                  1.       The form of agreements supplied to us that we
                           reviewed in connection with rendering our opinions
                           hereunder will be validly executed in substantially
                           the same form in which they have been filed as
                           exhibits to the Registration Statement and will be
                           binding and enforceable in accordance with their
                           terms.

                  2.       All parties will perform under such agreements in
                           accordance with their terms.

                  3.       There are no other or further agreements which would
                           alter, amend or otherwise materially affect the
                           relationships created by or described in the above
                           listed documents or described in the Registration
                           Statement, or which would affect the Seller's
                           interest in the Retained Yield.

                  Our opinions represent only our best judgment regarding the
application of federal income tax laws under the Internal Revenue Code of 1986,
as amended (the "Code"), existing judicial decisions, administrative regulations
and published rulings and procedures. Our opinion is not binding upon the
Internal Revenue Service or the courts, and there is no assurance that the
Internal Revenue Service will not successfully assert contrary positions.
Furthermore, no assurance can be given that future legislative, judicial
decisions or administrative changes, applicable either on a prospective or
retroactive basis, might not materially
<PAGE>   3
December 10, 1996
Page 3


alter our opinions. Nevertheless, we undertake no responsibility to advise you
of any new developments in the application or interpretation of the federal
income tax laws.

                  Based on and subject to the foregoing, we are of the opinion
that:

                  A. The Trust will not be classified as a partnership or as an
association taxable as a corporation for federal income tax purposes and, 
instead, under Subpart E, Part I of Subchapter J of the Code, will be treated 
as a grantor trust and, subject to possible recharacterization of certain 
amounts paid by the Trust to the Servicer, the holders of the Certificates 
will be treated as owning an undivided pro-rata interest in the income and 
corpus of the Trust (other than the Retained Yield);

                  B. The statements in the Prospectus under the headings
"Prospectus Summary -- Tax Status" and "Certain Tax Consequences," to the extent
that they constitute matters of law or legal conclusions with respect thereto,
are correct in all material respects; and

                  C. The Trust will not be subject to California franchise or
income taxation and individual holders of Certificates who are not residents of
or otherwise subject to tax in California will not be subject to California
income taxation on any income earned with respect to their investment in the
Certificates so long as they do not hold the Certificates as an asset of a trade
or business conducted in California.

                  We express no opinion as to other tax issues affecting the
purchasers of the Certificates or the other parties to any of the agreements,
nor does our opinion address state, local or foreign tax consequences that may
result from the transactions.

                  We consent to the use of this opinion as an exhibit to the
Registration Statement and further consent to all references to us in the
Registration Statement, the prospectus constituting a part thereof and any
further amendments thereto. Subject to the foregoing sentence, this opinion is
given as of the date hereof solely for your benefit and may not be relied upon,
circulated, quoted or otherwise referred to for any purpose without our prior
written consent.

                                  Respectfully,


                                  /s/ Brobeck Phleger & Harrison LLP
