                                SUMMARY OF TERMS

      The following summary is a short, concise description of the information
contained elsewhere in this prospectus. For this reason, the summary does not
contain all of the information that may be important to you. To fully understand
the terms of the offering of the securities, you will need to read both this
prospectus and the related prospectus supplement, each in its entirety.


THE ISSUER

A separate trust will be formed with respect to each series of securities. The
seller will form each trust by entering into either:

    -   a trust agreement among the Seller and the trustee for the trust; or

    -   a pooling and servicing agreement among the seller, the servicer and the
        trustee for the trust.

THE SELLER

Onyx Acceptance Financial Corporation, a Delaware corporation and a
wholly-owned, limited purpose subsidiary of Onyx Acceptance Corporation. The
seller's principal executive offices are located at 27051 Towne Centre Drive,
Suite 200, Foothill Ranch, California 92610, and its telephone number is (949)
465-3500. See "The Seller" in this prospectus.

THE SERVICER

Onyx Acceptance Corporation, a Delaware corporation. The servicer's principal
executive offices are located at 27051 Towne Centre Drive, Suite 100, Foothill
Ranch, California 92610, and its telephone number is (949) 465-3900. See "The
Servicer" in this prospectus.

THE TRUSTEE

Each prospectus supplement will specify the trustee of the trust for that series
of securities.

THE INDENTURE TRUSTEE

With respect to any series of securities that includes one or more classes of
notes, the prospectus supplement will specify the indenture trustee for that
series of securities in the related prospectus supplement.

THE DISTRIBUTION DATE

Interest and principal on the notes and the certificates will be payable on the
date set forth in the related prospectus supplement.

THE NOTES

A series of securities may include one or more classes of notes. The notes
issued by each trust will be governed by an indenture between the trust and an
indenture trustee. We will specify, in the related prospectus supplement, which
class or classes of notes, if any, will be offered in connection with the
issuance of a series.

Principal and Interest on the Notes

Except as described below with respect to strip notes, each class of notes will
have a stated note principal balance specified in the related prospectus
supplement. The notes will accrue interest on the stated note principal balance
at a specified interest rate. Each class of notes may have a different interest
rate. The interest rate may be fixed, variable or adjustable, or any combination
of fixed, variable and adjustable. We will specify the interest rate for each
class of notes, or the method for determining such


                                        1

<PAGE>   7

interest rate, in the related prospectus supplement.

If a series includes two or more classes of notes, as specified in the related
prospectus supplement, each class may differ as to:

    -   timing and priority of payments;

    -   seniority of payments;

    -   allocations of losses;

    -   calculation or amount of the interest rate;

    -   amount of payments of principal or interest;

    -   whether or not payments of principal and interest will be delayed or not
        made at all upon the occurrence of specified events; and

    -   whether payments of principal and interest may or may not be made from
        designated portions of the pool of contracts.

THE CERTIFICATES

A series of securities may include one or more classes of certificates. The
certificates will be governed by a trust agreement. We will specify, in the
related prospectus supplement, which class or classes of certificates, if any,
will be offered in connection with the issuance of a series.

Principal and Interest on the Certificates

Except as described below with respect to strip certificates, each class of
certificates will have a stated principal balance specified in the related
prospectus supplement. The certificates will accrue interest on the applicable
stated principal balance at a specified interest rate. Each class of
certificates may have a different interest rate. The interest rate may be fixed,
variable or adjustable, or any combination of fixed, variable and adjustable. We
will specify the interest rate for each class of certificates or the method for
determining such certificate rate in the related prospectus supplement.

Subordination to Notes

If a series of securities includes classes of notes and certificates,
distributions on the certificates may be subordinated to payments on the notes
to the extent specified in the related prospectus supplement.

OPTIONAL REDEMPTION

If the seller, the servicer or a successor to the seller or the servicer
exercises its option to purchase the contracts of the trust, the notes and
certificates then outstanding will be redeemed as set forth in the related
prospectus supplement. See "Description of the Transfer and Servicing Agreements
- - Termination" in this prospectus.


A TRUST MAY ISSUE MULTIPLE CLASSES OF SECURITIES WITH DIFFERENT CHARACTERISTICS


Each trust may issue more than one class of notes and certificates. In these
cases, the characteristics of the securities in each class may differ from one
another. Some of these characteristics are:

     -   timing and priority of payments;

     -   seniority of payments;

     -   allocations of losses;

     -   calculation or amount of the interest rate;

     -   amount of distribution of principal or interest;

                                        2

<PAGE>   8

     -   whether or not distributions of principal and interest will be delayed
         or not made at all upon the occurrence of specified events; and

     -   whether distributions of principal and interest may or may not be made
         from designated portions of the pool of contracts.

Any differences in characteristics will be specified in the prospectus
supplement.

STRIP SECURITIES MAY BE ISSUED

In addition, a trust might issue one or more classes of notes or certificates
providing for distributions of interest which are disproportionately large or
small in comparison to principal distributions, including:

     -   principal distributions with disproportionate, nominal or no interest
         payments; or

     -   interest distributions with disproportionate, nominal or no principal
         payments.

THE TRUST PROPERTY


The contracts supporting the securities of each trust will consist of a pool of
motor vehicle retail installment sale contracts and/or installment loan
agreements, each of which is secured by a new or used automobile, light-duty
truck or van, and other property, including:


     -   documents relating to the contracts;

     -   monies received with respect to the contracts on or after the cut-off
         date specified in the related prospectus supplement;

     -   security interests in the vehicles financed by the contracts;

     -   the rights to receive proceeds from claims on various insurance
         policies covering the financed vehicles or the individual obligors
         under each related contract;


     -   all amounts on deposit in specified accounts identified in the related
         prospectus supplement, including, to the extent described in the
         related prospectus supplement, eligible investments credited to those
         accounts;


     -   the benefits of any form of credit enhancement identified in the
         applicable prospectus supplement;

     -   the right of the seller to cause Onyx to repurchase contracts in
         particular circumstances; and

     -   all proceeds of the foregoing.

See "The Trusts" in this prospectus.

The seller will sell or transfer contracts to the trust on or before the closing
date on which a specified series of securities is issued, as set forth in the
related prospectus supplement. The prospectus supplement will specify the
aggregate principal balance of the contracts initially transferred to the trust.
If the trust related to a series of securities will be treated as an owner trust
for federal income tax purposes, the seller will sell the contracts to the trust
under a sale and servicing agreement among the seller, the servicer and the
trust. Alternatively, if the trust will be treated as a grantor trust for
federal income tax purposes, the seller will transfer the contracts to the trust
under a pooling and servicing agreement among the seller, the servicer and the
trustee.

Other Property of the Trust

In addition to the contracts, each trust will own amounts on deposit in various
trust accounts, which may include:

                                        3

<PAGE>   9

     -   an account into which collections are deposited;

     -   an account to fund post-closing purchases of additional contracts;

     -   a spread account, reserve account or other account relating to credit
         enhancement; and

     -   any other account identified in the related prospectus supplement.

THE CONTRACTS

The contracts included in the property of each trust will have been:

     -   either originated by automobile dealerships and assigned to Onyx, or
         purchased or originated by subsidiaries of Onyx;

     -   purchased by the seller from Onyx or from a subsidiary of Onyx; and

     -   purchased by the trust from the seller.

See "The Onyx Portfolio of Motor Vehicle Contracts" in this prospectus. All of
the contracts included in the property of each trust will be selected based upon
the criteria specified in the related sale and servicing agreement or pooling
and servicing agreement, as applicable.

PREFUNDING ARRANGEMENTS

With respect to any series of securities, the trust may commit to purchase
additional contracts from the seller following the date on which the trust is
established and the related securities are issued.  See "Prefunding
Arrangements" in this prospectus.  We will describe any such prefunding
arrangements in the related prospectus supplement.

CREDIT AND CASH FLOW ENHANCEMENT

We may structure the securities of any series to include credit enhancement for
one or more classes of securities. Such credit enhancement may include any one
or more of the following:

     -   a surety bond or financial guarantee insurance policy provided by a
         third- party insurer;

     -   subordination of one or more classes of securities to one or more other
         classes of securities;

     -   a reserve fund;

     -   a yield maintenance account;

     -   over-collateralization;

     -   letters of credit;

     -   credit or liquidity facilities;

     -   guaranteed investment contracts;

     -   swaps or other interest rate protection agreements;

     -   repurchase obligations;

     -   cash deposits;

     -   other agreements or arrangements with respect to third party payments;
         or

     -   other support.

We will describe any such credit enhancement, including any limitations and
exclusions from coverage, in the related prospectus supplement. See "Description
of the Transfer and Security Agreements - Credit and Cash Flow Enhancement" in
this prospectus.

TAX STATUS

If the prospectus supplement specifies that the related trust will be treated as
an owner trust, upon the issuance of a series of securities, tax counsel to the
trust will deliver an opinion to the effect that:

     -   any notes of such series will be characterized as debt for federal
         income tax purposes; and

     -   the trust will not be characterized as an association or a publicly
         traded partnership taxable as a corporation for federal income tax
         purposes.

If the prospectus supplement specifies that the related trust will be treated as
a grantor trust, upon the issuance of the related series of certificates, tax
counsel to the trust will deliver an opinion to the effect that:

     -   the trust will be treated as a grantor trust for federal income tax
         purposes; and

     -   the trust will not be subject to federal income tax.

See "Certain Federal Income Tax Consequences" in this prospectus for additional
information concerning the application of federal tax laws.

ERISA CONSIDERATIONS

Administrators of employee benefit plans should review the matters discussed
under "ERISA Considerations" in this prospectus and the related prospectus
supplement.

RATING

At the closing date of each series of securities, each class of securities in
such series will be rated in one of the four highest generic rating categories
established for such securities by at least one nationally recognized
statistical rating agency.

REGISTRATION OF THE SECURITIES

The securities may be available only in book-entry form. Each investor's
interest in the securities would be represented through an agent, rather than by
a physical note or certificate held by the investor. A trust will not issue
physical securities to investors unless specific events occur which make it
necessary or desirable to do so. See "Description of the Securities - Definitive
Securities" in this prospectus.

                                  RISK FACTORS

INTERESTS OF OTHER PERSONS IN THE CONTRACTS COULD REDUCE THE FUNDS AVAILABLE TO
MAKE PAYMENTS ON THE SECURITIES.


         In connection with the sale of contracts to a trust, the seller will
assign the security interests in the financed vehicles securing those contracts
to the trust at the time of sale. If a series of securities includes one or more
classes of notes, the trust will pledge the security interests in the financed
vehicles to the related indenture trustee. Due to the administrative burden and
expense, the certificates of title to the financed vehicles will not be amended
to reflect the assignment to the trust or the indenture trustee. In the absence
of such an amendment, the trust and the indenture trustee may not have perfected
security interests in the financed vehicles securing the contracts in some
states. If the trust or the indenture trustee does not have a perfected security
interest in a financed vehicle, the collections on that contract and the
proceeds from the sale of the financed vehicle securing that contract may not be
available to make payment on the securities.


         The security interest of the trust and, if applicable, the indenture
trustee, could be impaired for one or more of the following reasons:

          -    Onyx or one of its subsidiaries might fail to perfect its
               security interest in a contract;

          -    Onyx or one of its subsidiaries might fail to perfect its
               security interest in a financed vehicle;

          -    the trust may not have a security interest in the financed
               vehicles in all states because the certificates of title to the
               financed vehicles will not be amended to reflect assignment to
               the trust;

          -    holders of some types of liens, such as tax liens or mechanics
               liens, may have priority over the trust's security interest;

          -    the trust could lose its priority to a person who obtains
               physical possession of a contract without knowledge of the
               assignment of the contract to the trust; and

          -    the trust could lose its security interest or its priority
               through fraud or negligence.

Neither the seller nor the servicer will be required to repurchase a contract if
the security interest in the contract or the related financed vehicle becomes
impaired after the contract is sold to the trust. See "Certain Legal Aspects of
the Contracts" in this prospectus.

BANKRUPTCY OF ONYX COULD RESULT IN DELAYS IN PAYMENT OR LOSSES ON THE SECURITIES

         If Onyx or a subsidiary of Onyx becomes subject to bankruptcy
proceedings, you could experience losses or delays in payments on your
securities. Onyx and each selling subsidiary of Onyx will transfer contracts to
the seller in a structure intended to constitute a "true sale." If the transfer
does constitute a "true sale," the applicable contracts and the proceeds thereof
would not be part of Onyx's or

                                        6

<PAGE>   12

its subsidiary's bankruptcy estate should Onyx or its subsidiary become the
subject of a bankruptcy case. However, if Onyx or a selling subsidiary of Onyx
becomes subject to a bankruptcy proceeding, a court in bankruptcy could conclude
that Onyx or its subsidiary still owns the contracts by concluding that the sale
to the seller was not a "true sale" or that the seller should be consolidated
with Onyx. If a court were to reach this conclusion, you could experience losses
or delays in payments on your securities.


         Onyx and the seller have taken and will take steps to structure the
sale of contracts to minimize the risk that a court would consolidate the seller
with Onyx for bankruptcy purposes or conclude that the sale of contracts to the
seller was not a "true sale." These steps include the creation of the seller as
a separate, limited purpose subsidiary of Onyx. The seller's certificate of
incorporation contains limitations which restrict the nature of the seller's
business. Further, the seller's certificate of incorporation restricts the
seller's ability to commence a voluntary case or proceeding in bankruptcy
without the prior unanimous affirmative vote of all of its directors. See "The
Seller" in this prospectus.

         The trustee, the seller, the servicer and all holders of securities
will covenant that they will not at any time institute against the seller or the
trust any bankruptcy, reorganization or other proceeding under any federal or
state bankruptcy or similar law.

PREPAYMENTS MAY ADVERSELY AFFECT THE AVERAGE LIFE AND YIELDS OF THE SECURITIES.

         The rate of payment of principal on the securities of each series
depends primarily on the rate of payments, including prepayments, on the
principal balance of the related contracts. As a result, final payment on any
class of securities could occur significantly earlier than the maturity date set
forth in the related prospectus supplement.

         All of the contracts may be prepaid at any time. Prepayments may
include all of the following:

          -    an obligor on a contract makes payments, in whole or in part,
               earlier than scheduled;

          -    the servicer liquidates a defaulted contract; and

          -    the servicer or seller is required to purchase or repurchase, as
               the case may be, a contract from the trust.

         Onyx cannot predict the actual prepayment rates that will occur on the
contracts in either stable or changing interest rate environments. See "Maturity
and Prepayment Considerations" in this prospectus and in the prospectus
supplement.

SUBORDINATION MAY CAUSE SOME CLASSES OF SECURITIES TO BEAR ADDITIONAL CREDIT
RISK.

         Payments of interest and principal on one or more classes of securities
of a series may be subordinated to one or more other classes of securities of
the same series. Subordination of a class of securities has the effect of
increasing the likelihood of payment on the senior classes in that series and
decreasing the likelihood of payment on the subordinated classes of that series.
A class of securities may be subordinated to another class of securities in that
series with respect to timing and priority of


                                        7

<PAGE>   13

payment, seniority and allocations of losses, among other things. Any
subordination will be described in the related prospectus supplement.

ONLY THE ASSETS OF THE TRUST ARE AVAILABLE TO MAKE PAYMENTS ON THE SECURITIES.

         No trust will have, nor is a trust permitted or expected to have, any
significant assets or sources of funds other than the related contracts and the
other assets described in the related prospectus supplement. The notes of any
series will represent obligations solely of the related trust. The certificates
of any series will represent interests solely in the related trust. None of the
seller, the servicer or any of their respective affiliates, the trustee, or any
indenture trustee will insure or guarantee the notes or the certificates of any
series. Accordingly, you must rely upon payments on the contracts and amounts,
if any, available from the other assets specified in the related prospectus
supplement for repayment on the securities.

FAILURE TO COMPLY WITH CONSUMER PROTECTION LAWS MAY AFFECT THE ENFORCEABILITY OF
THE CONTRACTS.

         Federal and state governments have enacted consumer protection laws
which apply to the contracts. These laws impose requirements with respect to the
making, transfer, acquisition, enforcement and collection of consumer contracts
and loans. These laws, as well as any new laws or rules which may be adopted,
may adversely affect the servicer's ability to collect on the contracts. If the
originator of the contracts or the servicer fails to comply with these consumer
protection laws, the contracts may not be enforceable. The seller will make
representations and warranties to the trust stating that the related contracts
are valid and enforceable and that the related contracts complied with
applicable law at the time they were made. Accordingly, the seller will be
obligated to repurchase each contract that does not comply with the applicable
requirements of any consumer protection law if the applicable trust's interest
in that contract is materially and adversely affected by such noncompliance. The
repurchase obligation of the seller is the sole remedy if the contract does not
comply with the representations and warranties of the seller within the
applicable cure period. See "Description of the Transfer and Servicing
Agreements - Repurchase of Contracts" and "Certain Legal Aspects of the
Contracts - Repurchase Obligation" in this prospectus.

IF BOOK-ENTRY REGISTRATION IS USED, YOU MAY BE ABLE TO EXERCISE YOUR RIGHTS AS A
SECURITYHOLDER ONLY THROUGH THE CLEARING AGENCY.


         If the prospectus supplement specifies that securityholders of the
trust will hold their interests through a clearing agency or one of its
participating organizations, the securities will be registered in the name of a
nominee of the clearing agency and physical certificates will not be issued to
individual securityholders. You will not be recognized as a securityholder
directly by the trustee of the trust or the indenture trustee and must exercise
all of your rights and receive any payments through the clearing agency or the
participating organization, unless physical certificates are issued. Your
ability to pledge your securities to persons or entities that are not
participating organizations of the clearing agency may be limited due to lack of
a physical certificate. Physical certificates will only be issued in limited
circumstances. See "Description of the Securities--Book-Entry Registration" in
this prospectus.


         Additionally, you may experience some delay in your receipt of payments
or distributions of interest and principal since the payments or distributions
will be provided by the trustee or indenture


                                        8

<PAGE>   14

trustee to the clearing agency and the clearing agency will credit the payments
or distributions to the accounts of its participants. The participants will then
credit the payments or distributions to your account either directly or
indirectly through the clearing agency's indirect participants. The clearing
agency in the United States is expected to be DTC, and in Europe either
Cedelbank or Euroclear.


                                   THE TRUSTS

         With respect to each series of securities, the seller will establish a
separate trust under either a trust agreement or a pooling and servicing
agreement, as applicable, to issue each series of notes and certificates. The
trust will be established for the transactions described in this prospectus and
the related prospectus supplement. The property of the trust will include:

          -    the related contracts,

          -    documents relating to the contracts,

          -    monies received with respect to the contracts on or after the
               cut-off date specified in the related prospectus supplement,

          -    security interests in the related financed vehicles and the
               rights to receive proceeds from claims on insurance policies
               covering such financed vehicles or the individual obligors under
               each related contract,

          -    amounts on deposit in certain specified accounts, including, to
               the extent described in the related prospectus supplement,
               eligible investments credited to such accounts;

          -    the benefits of any form of credit enhancement identified in the
               related prospectus supplement;

          -    the right of the seller to cause Onyx to repurchase contracts
               under some circumstances, and

          -    all proceeds of the foregoing.

To the extent specified in the related prospectus supplement, a security
insurance policy, reserve fund or other form of credit enhancement may be a part
of the property of the trust or may be held by the trustee or an indenture
trustee for the benefit of holders of the related securities.

         Prior to formation, the trust will have had no assets or obligations.
After formation, the trust will not engage in any activity other than acquiring
and holding the related contracts, issuing the related securities, distributing
payments in respect thereof and as otherwise described in this prospectus, in
the related prospectus supplement and in the trust agreement or pooling and
servicing agreement, as applicable. The trust will not acquire any contracts or
assets other than the trust property.


                                        9

<PAGE>   15

         The principal offices of each trust that is not a grantor trust and the
related trustee will be specified in the applicable prospectus supplement.


                      THE TRUSTEE AND THE INDENTURE TRUSTEE

         The trustee for each trust and, if applicable, the indenture trustee,
will be specified in the related prospectus supplement. The trustee's and the
indenture trustee's liability in connection with the issuance and sale of the
related securities will be limited solely to the express obligations of the
trustee or indenture trustee set forth in the related trust agreement, sale and
servicing agreement, and indenture or the related pooling and servicing
agreement, as applicable.


                  THE ONYX PORTFOLIO OF MOTOR VEHICLE CONTRACTS

PURCHASE AND ORIGINATION OF MOTOR VEHICLE CONTRACTS

         Onyx's portfolio of motor vehicle contracts consists of retail
installment sales contracts and installment loan agreements secured by new and
used automobiles, light-duty trucks and vans. Onyx targets the prime auto
lending market because it believes that prime lending produces greater
origination and operating efficiency than does sub-prime lending. Onyx focuses
on late model used, rather than new, vehicles, as management believes the risk
of loss on used vehicles is lower due to lower depreciation rates, while
interest rates are typically higher. In addition, Onyx believes that the late
model used motor vehicle finance market is growing at a faster rate than is the
finance market for new motor vehicles.


         Onyx has three auto lending programs:

         -     the "premier" program;

         -     the "preferred" program; and

         -     the "standard" program.

The premier program allows Onyx to market lower interest rates in order to
capture customers of superior credit quality. The preferred program allows Onyx
to offer contracts at higher interest rates to borrowers with proven credit
quality. The standard program allows Onyx to assist qualified borrowers, who
may have experienced previous credit problems or have not yet established a
significant credit history, at interest rates higher than the premium and
preferred programs.


         Onyx generally acquires the contracts in its portfolio through one or
more of the following methods:

          -    Onyx purchases contracts from automobile dealers that originate
               the contracts;

          -    a subsidiary of Onyx purchases contracts from credit unions or
               others that originate the contracts; and

          -    a subsidiary of Onyx originates the contracts.

Onyx anticipates that substantially all of the contracts included in the trust
property of a trust will have been purchased by Onyx from new and used car
dealers unaffiliated with Onyx and the seller, with a limited number of
contracts having been purchased or originated by subsidiaries of Onyx. All of
the contracts will have been sold to the seller and then to the trust. The
dealers are located in metropolitan areas in which the contracts are or will be
originated. Each dealer, credit union or other party from which Onyx or a
subsidiary of Onyx purchases contracts has entered into an agreement with Onyx
or its subsidiary under which the dealer, credit union or other seller
represents that:

          -    it will comply with federal and state laws regarding motor
               vehicle financing;

                                       10

<PAGE>   16

          -    it will obtain the requisite financial information required of
               the obligor in order to extend credit; and

          -    it will truthfully disclose to Onyx or Onyx's subsidiary such
               financial information, the identity of the obligor and other
               information in connection with the 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 contracts for Onyx to
purchase. Before purchasing contracts from an independent used car dealer, Onyx
completes a credit review of the dealer's financial condition, which includes a
review of financial information provided by the dealer and a Dun & Bradstreet
report on the dealer, and also completes a review of the underwriting criteria
used by the dealer. The payment obligations of the obligor under each contract
are secured by the vehicle purchased with the proceeds provided under that
contract.

         Onyx services all of the contracts and initially will serve as the
primary servicer of the contracts included in the trust property of a trust
after they are sold by the seller to the trust. The servicing functions
performed by Onyx include:

          -    customer service;

          -    document filekeeping;

          -    computerized account record keeping;

          -    vehicle title processing; and

          -    collections.

UNDERWRITING

         Onyx underwrites contracts purchased from dealers through its regional
auto finance centers located throughout the United States. Contracts purchased
from dealers in other states are generally purchased by the auto finance center
that is geographically most proximate to the state of origination. In the case
of contracts originated by a subsidiary of Onyx, such contracts are underwritten
at Onyx's Foothill Ranch, California location. Generally, each 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 actuarial method, the rule of 78's method or the simple interest method. See
"The Contracts" in this prospectus.

         In determining whether to purchase a contract originated by a dealer or
whether to directly originate a contract, Onyx or a subsidiary of Onyx reviews
an application package concerning the applicant and the proposed contract. The
application package sets forth information concerning the applicant, including:

          -    the applicant's income;


                                       11

<PAGE>   17

          -    the applicant's liabilities;

          -    the applicant's credit and employment history;

          -    other personal information about the applicant; and

          -    a description of the financed vehicle that secures or will secure
               the contract.

Most credit applications are not made on forms provided by Onyx or a subsidiary
of Onyx. However, Onyx or a subsidiary of 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 or a subsidiary of Onyx reviews information in the
application and from credit bureau reports obtained by Onyx or its subsidiary.

         Each proposed contract is evaluated using uniform underwriting
standards developed by Onyx. These underwriting standards are intended to assess
the applicant's ability to repay all amounts due under the contract and the
adequacy of the related financed vehicle as collateral, based upon a review of
the information contained in the contract application. Among the criteria
considered by credit managers of Onyx and its subsidiaries in evaluating the
individual applications are:

          -    stability of the applicant with specific regard to the
               applicant's occupation, length of employment and length of
               residency;

          -    the applicant'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;

          -    a debt service-to-gross monthly income ratio test; and

          -    the principal amount of the contract taking into account the age,
               type and market value of the related financed vehicle.

         After review of an application, a credit manager, via an electronic
system, communicates an appropriate decision to the dealer or other appropriate
party specifying approval, denial or a counter-offer on the proposed contract.
If the response requires stipulations to the approval, these are communicated
concurrently to the dealer or other party and become a condition of the
approval. After approval, if Onyx or a subsidiary of Onyx is the chosen source
of financing, Onyx or its subsidiary will obtain the necessary documentation for
processing, which consists of the following:

          -    a signed credit application;

          -    the only original and a copy of the executed contract;

          -    an agreement by the applicant to provide insurance;

          -    a report of sale or guarantee of title;


                                       12

<PAGE>   18

          -    an application for registration;

          -    a co-signer notification, if applicable;

          -    a copy of any supplemental warranty purchased with respect to the
               financed vehicle;

          -    acceptable vehicle valuation documentation; and

          -    any other required documentation.

         Once the appropriate documentation is in hand for funding, the file
relating to the contract is ready to forward to a contract processor for a
pre-funding audit. The contract processor, who is employed by Onyx or one of its
subsidiaries, then audits the documents for completeness and consistency with
the application, providing final approval for purchase of the contract once
these requirements have been satisfied.


         The amount advanced by Onyx or a subsidiary of Onyx under any contract
generally does not exceed the manufacturer's suggested retail price for a new
financed vehicle, or the value assigned by a nationally recognized used car
value guide for a used financed vehicle, in either case plus taxes, title and
license fees, any extended warranty and any credit and other insurance. However,
the actual amount advanced for a contract is often less than the maximum
permissible amount depending on a number of factors, including the length of the
contract term and the model and year of the related financed vehicle. These
adjustments are made to assure that the related financed vehicle constitutes
adequate collateral to secure the contract. Under no circumstances is the amount
advanced for a contract greater than the amount payable by the applicant with
respect to the purchase of the related financed vehicle.


         Periodically, Onyx makes a detailed analysis of its portfolio of
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 contracts by
conducting audits of randomly selected contracts to ensure compliance with
established policies and procedures.

INSURANCE

         Each contract requires the obligor to obtain comprehensive and
collision insurance with respect to the related financed vehicle with Onyx or a
subsidiary of Onyx as a loss payee. Onyx tracks whether obligors maintain the
required insurance.

COLLECTION PROCEDURES

         Onyx performs collection activities with respect to delinquent
contracts at its Foothill Ranch, California collection center. 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 at least 90% of a scheduled payment under the contract within 30 days of
the due date.

                                       13

<PAGE>   19

         To automate its collection procedures, Onyx uses features of the
computer system of its third party service bureau, Online Computer Systems, Inc.
to provide tracking and notification of delinquencies. The collection system
provides relevant obligor information and records of all contracts. The system
also maintains a record of an obligor's promise to pay and affords supervisors
the ability to review collection personnel activity and to modify collection
priorities with respect to contracts. Onyx utilizes a predictive dialing system
located at its Foothill Ranch, California collection center to make phone calls
to obligors whose payments are past due by more than eight 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
200 to 250 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 collections 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 on a contract is 20 days or more delinquent, the
account is assigned to a specific collector at the Foothill Ranch, California
collection center who will have primary responsibility for the delinquent
account until it is resolved. To expedite collections from late paying obligors,
Onyx uses Western Union "Quick Collect," which allows an obligor to make late
payments at numerous locations, which are in turn wired daily to Onyx's lockbox
account by Western Union. Onyx also uses a Western Union 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 contract continues to be
past due for between 45 and 60 days, Onyx will initiate repossession of the
financed vehicle. However, if the applicable contract is deemed uncollectible,
if the related financed vehicle is deemed by collection personnel to be in
danger of being damaged, destroyed or made unavailable for repossession, or if
the related obligor voluntarily surrenders the related financed vehicle, Onyx
may repossess the related financed vehicle 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 the laws of California and most other states in which contracts are
originated, after repossession, the obligor generally has an additional period
of 10 to 15 days to redeem a financed vehicle before it may be resold by Onyx in
an effort to recover the balance due under the contract.

         Losses may occur in connection with delinquent contracts and can arise
in several ways, including inability to locate the related 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
contract is deemed uncollectible or during the month a scheduled payment under a
contract becomes 120 days or more past due, whichever occurs first.

         Upon repossession and sale of a 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 sale and servicing agreement or pooling and servicing
agreement, as applicable, will require that Onyx service the contracts and
collect all amounts due using


                                       14

<PAGE>   20

reasonable care and in at least the same manner as it services and collects
amounts due with respect to contracts serviced by it for its own account.

MODIFICATIONS AND EXTENSIONS

         Onyx offers credit-related extensions to obligors. Generally, these
extensions are offered only when:

          -    Onyx believes that the obligor's financial difficulty has been
               resolved or will no longer impair the obligor's ability to make
               future payments;

          -    the extension will result in the obligor's payments being brought
               current;

          -    the total number of credit-related extensions granted on the
               contract will not exceed three;

          -    the total time of credit-related extensions granted on the
               contract will not exceed three months in the aggregate;

          -    there has been no more than one credit-related extension granted
               on the contract in the immediately preceding twelve months; and

          -    Onyx or its assignee has held the contract for at least six
               months.

Any deviation from this policy requires the concurrence of a collection
supervisor and Onyx's collection manager and the Executive Vice President,
Collections.

DELINQUENCY AND LOAN LOSS INFORMATION

         Certain information concerning the experience of Onyx pertaining to
delinquencies, loan losses and recoveries with respect to its portfolio of
contracts, including receivables previously sold which Onyx continues to
service, will be set forth in each prospectus supplement. There can be no
assurance that the delinquency, loan loss and recovery experience on any
contracts related to a series of securities will be comparable to prior
experience or to that information.

ALLOCATION OF PAYMENTS ON CONTRACTS TO INTEREST AND PRINCIPAL

         If so provided in the prospectus supplement, each of the contracts in
the trust property of a trust will be a fixed rate contract where the allocation
of each payment between interest and principal is calculated using one of the
three methods described below - the simple interest method, the actuarial method
and the rule of 78's method.

         SIMPLE INTEREST METHOD. Under the simple interest method, interest due
is calculated on the scheduled due date based on the actual principal balance of
the contract on that date. For simple interest contracts, interest accrued as of
the scheduled due date is paid first, and then the remaining payment is


                                       15

<PAGE>   21

applied to the unpaid principal balance. Accordingly, if an obligor pays the
fixed monthly installment in advance of the scheduled 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 as scheduled; 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 scheduled
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 as scheduled; 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.

         ACTUARIAL METHOD. Under the actuarial method, contracts provide for
amortization over a series of fixed level payment monthly installments, whereby
each monthly installment, including the monthly installment representing the
final payment on the contract, consists of:

          -    an amount of interest equal to 1/12 of the annual percentage
               rate, or APR, of the contract multiplied by the unpaid principal
               balance of the contract; and

          -    an amount of principal equal to the remainder of the monthly
               payment.

         RULE OF 78'S METHOD. Under the rule of 78's method, contracts 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 the contract were a
self-amortizing, level-yield contract bearing interest at an APR equal to the
stated APR set forth in the contract. 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 rule of 78's contract 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 rule of 78's contract
providing for 12 payments, the denominator of each month's fraction will be 78,
the sum of the 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 rule of 78's 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

                                       16

<PAGE>   22

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.

         The purchase price paid by a trust for each contract included in the
trust property of the trust will reflect the principal balance of the contract
as of the cut-off date. The cut-off date principal balance of the contract will
be calculated under the simple interest method, the actuarial method or the rule
of 78's method, as appropriate, or otherwise as described in the related
prospectus supplement. 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 principal balance of
each rule of 78's contract will exceed the amount that would have been its
cut-off date principal balance under the actuarial method. The trustee or, if
applicable, indenture trustee, and the servicer will account for interest and
principal on rule of 78's contracts using the actuarial method, but based on the
cut-off date principal balance. The remaining payments due on a rule of 78's
contract will not be sufficient to amortize the cut-off date principal balance
of the contract at a yield equal to its APR. Accordingly, in order to amortize
the cut-off date principal balance over the remaining term of the rule of 78's
contract using the actuarial method, the servicer will:

          -    recompute the effective yield of the contract based on the
               remaining payments due and the cut-off date scheduled balance;
               and

          -    will allocate each scheduled payment of principal and interest
               between principal and interest on each rule of 78's contract
               based on the cut-off date principal balance and the recomputed
               yield for the contract.

WE WILL PROVIDE MORE SPECIFIC INFORMATION ABOUT THE CONTRACTS IN THE PROSPECTUS
SUPPLEMENT

         We will provide information about each contracts pool in the related
prospectus supplement, including, to the extent appropriate:

          -    the portion of the contracts pool consisting of simple interest
               contracts, actuarial contracts and rule of 78's contracts;

          -    the portion of the contracts pool secured by new vehicles and by
               used vehicles;

          -    the aggregate principal balance of all of the contracts;

          -    the number of contracts;

          -    the average outstanding principal balance of the contracts;

          -    the average original amount financed and the range of original
               amount financed;

          -    the weighted average APR and the range of APR's;

          -    the weighted average original term and the range of original
               terms;

                                       17

<PAGE>   23

          -    the weighted average remaining term and the range of remaining
               terms; and

          -    the distribution of the contracts by APR and by state of
               origination.

                             PREFUNDING ARRANGEMENTS

         If so provided in the related prospectus supplement for a series of
Securities, a trust may be required to purchase additional contracts from the
seller following the date on which the trust is established and the related
securities are issued. With respect to a series of securities, the prefunding
arrangement will require that any additional contracts transferred to the trust
conform to the requirements and conditions provided in the related sale and
servicing agreement or pooling and servicing agreement, as applicable. If a
prefunding arrangement is utilized in connection with the issuance of a series
of securities, the servicer will establish a prefunding account in the name of
the related trustee or indenture trustee, as applicable, for the benefit of the
securityholders, into which all or a portion of the net proceeds received from
the sale of the securities will be deposited and from which monies will be
released during a specified period to purchase additional contracts from the
seller. Upon each conveyance of additional contracts to the trust, an amount
equal to the purchase price paid by the seller to Onyx, or a subsidiary of Onyx,
for the additional contracts will be released from the prefunding account and
paid to the seller.

         The use of a prefunding arrangement for a series of securities is
intended to improve the efficiency of the issuance of the securities and the
sale of the contracts to the related trust through the incremental delivery of
the contracts on the closing date and during a specified period following the
closing date. This allows for a more even accumulation of the contracts by the
seller and by Onyx and its subsidiaries and the issuance of a larger principal
amount of securities than would be the case without a prefunding arrangement.


                     MATURITY AND PREPAYMENT CONSIDERATIONS

         The weighted average life of the securities of any trust will generally
be influenced by the rate at which the principal balances of the related
contracts are paid, which payment may be in the form of scheduled amortization
or prepayments. "Weighted average life" means the average amount of time in
which each dollar of principal on a contract is repaid. "Prepayments" for these
purposes include the following circumstances:

          -    prepayments in full;

          -    repurchases by the seller as a result of the failure of a
               contract to meet the criteria set forth in the related sale and
               servicing agreement or pooling and servicing 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
               related sale and servicing agreement or pooling and servicing
               agreement;


                                       18

<PAGE>   24

          -    partial prepayments;

          -    liquidations of the contracts due to default;

          -    receipts of proceeds from theft, physical damage, credit life and
               credit disability insurance policies; and


          -    optional repurchase by the servicer for administrative reasons.



         The contracts will be prepayable in full by the obligors at any time
without penalty. Full and partial prepayments on simple interest contracts and
full prepayments on actuarial and rule of 78's contracts will be paid or
distributed to the related securityholders on the distribution date following
the collection period in which they are received. Partial prepayments on
actuarial and rule of 78's contracts, however, will be treated as "payaheads"
and will not be paid or distributed until the collection period in which the
payaheads are due or until the amount of the partial prepayment equals the
amount the obligor would be required to pay in order to prepay the contract in
full. See "Description of the Transfer and Servicing Agreements - Payahead
Account".

         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 the contracts;

          -    destruction of vehicles by accident;

          -    sales of vehicles; and

          -    market interest rates.

         California law, and the law of some other states, requires that retail
installment sales contracts and installment loan agreements 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 the 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 can make no prediction as to the actual prepayment rates that will
be experienced on the contracts included in the trust property of any trust in
either stable or changing interest rate environments. Securityholders of each
series will bear all reinvestment risk resulting from the rate of


                                       19

<PAGE>   25

prepayment of the contracts. The related prospectus supplement may set forth
additional information with respect to the maturity and prepayment
considerations applicable to the particular contracts pool and the related
securities of the trust.



                        POOL FACTOR AND POOL INFORMATION

         The "pool factor" will be a six-digit decimal which the servicer will
compute each month indicating the aggregate outstanding principal balance of the
related pool of contracts at the end of the month as a fraction of the aggregate
principal balance of the contracts as of the cut-off date specified in the
related prospectus supplement. The pool factor will be 1.000000 as of the
closing date; thereafter, the pool factor will decline to reflect reductions in
the aggregate principal balance of the related contracts. The amount of a
securityholder's pro rata share of the aggregate outstanding principal balance
of the pool of contracts for a given month can be determined by multiplying the
original denomination of the holder's security by the pool factor for that
month.



         With respect to each trust, the related securityholders will receive
monthly reports from the trustee concerning payments received on the
contracts, the aggregate outstanding principal balance of the pool of
contracts, the pool factor, and various other items of information.
Securityholders of record during any calendar year will be furnished
information for tax reporting purposes not later than the latest date permitted
by law. See "Description of the Securities -- Statements to Securityholders".



                                 USE OF PROCEEDS

         The net proceeds from the sale of securities of a given trust will be
applied by the trust:

          -    to the purchase of the contracts from the seller;

          -    to make the initial deposit into any prefunding account;

          -    to make the initial deposit into any yield supplement account;

          -    to make the initial deposit, if any, into any reserve account,
               spread account or other similar account;

          -    for any other purposes specified in the related prospectus
               supplement.

         The seller will use the net proceeds to be received by the seller from
the sale of securities of a given series to repay indebtedness incurred in
connection with its acquisition of the contracts and to pay other expenses in
connection with the pooling of the contracts and the issuance of the securities.


                                   THE SELLER

         The seller is a wholly-owned, limited purpose finance subsidiary of
Onyx that 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 27051 Towne Centre Drive, Suite 200, Foothill Ranch, California
92610. The telephone number of the seller at its principal office is (949)
465-3500.

         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 motor
vehicle contracts from Onyx, transferring the contracts to third parties and any
activities incidental to and necessary or convenient for the accomplishment of
these purposes.

         Onyx and the seller have taken and will take steps in structuring the
transactions contemplated in this prospectus and the related prospectus
supplement that are intended to ensure that the voluntary or involuntary
application for relief by Onyx under any bankruptcy or 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 with a certificate of incorporation containing 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
bankruptcy or insolvency law


                                       20

<PAGE>   26

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 bankruptcy or
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 any bankruptcy or insolvency law to Onyx. 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 bankruptcy or
insolvency law by or against the seller, or if an attempt were made to litigate
any of the foregoing issues, delays in payments or distributions on any
outstanding series of securities could occur or reductions in the amounts of the
payments or distributions could result.

         Onyx, each selling subsidiary of Onyx and the seller intend that each
transfer of contracts by Onyx or a subsidiary of Onyx to the seller under the
sale and servicing agreement or pooling and servicing agreement, as applicable,
or otherwise, will constitute a "true sale" of the contracts to the seller. If a
transfer of contracts constitutes a "true sale," the contracts and their
proceeds would not be part of the bankruptcy estate of Onyx or a subsidiary of
Onyx under Section 541 of the bankruptcy code should Onyx or a subsidiary of
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 contracts to the seller, the transfer of
those contracts by Onyx to the seller 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 under Section 541 of the
bankruptcy code.


                                  THE SERVICER

         Onyx will initially service the contracts included in the trust
property of each trust. Onyx was incorporated in California in 1993 and
reincorporated in Delaware in 1996 in connection with its initial public
offering, which was successfully completed in March 1996. Onyx is engaged
principally in the business of providing indirect automobile financing to new
car dealerships and selected used car dealerships in California and in other
states across the country. Onyx is headed by a management team with extensive
experience in the origination and servicing of indirect and direct automobile
loans, and who, from 1985 to present, have actively participated in a number of
public securitizations of motor vehicle contracts. The common stock of Onyx is
listed on the NASDAQ. Onyx's principal executive offices are located at 27051
Towne Centre Drive, Suite 100, Foothill Ranch, California 92610.

                                       21

<PAGE>   27

         Onyx acquires individual contracts from dealers, and to a lesser extent
subsidiaries of Onyx purchase the contracts from credit unions or other parties
or directly originate the contracts, after reviewing and approving the
customer's credit application in accordance with its underwriting policies and
procedures. See "The Contracts". Onyx finances acquisitions and originations of
contracts on a short term basis through two separate warehouse facilities and
has previously financed acquisitions and originations of motor vehicle
installment contracts on a long term basis through sales of contracts to grantor
and owner trusts and periodically through whole loan sales.


                          DESCRIPTION OF THE SECURITIES

GENERAL

         With respect to each trust that issues notes, one or more classes of
notes of the related series will be issued under the terms of an indenture, a
form of which has been filed as an exhibit to the registration statement of
which this prospectus forms a part. With respect to each trust that issues
certificates, one or more classes of certificates of the related series will be
issued under the terms of a trust agreement or a pooling and servicing
agreement, a form of each of which has been filed as an exhibit to the
registration statement of which this prospectus forms a part. The following is a
summary of the material terms of the securities, but does not purport to be
complete and is subject to, and is qualified in its entirety by reference to,
all the provisions of the notes, certificates, indenture, trust agreement and
pooling and servicing agreement, as applicable, and the related prospectus
supplement.

         The securities of each series will be issued in the denominations
specified in the related prospectus supplement. The securities of each series
are expected to be issued in book-entry form. See "- Book-Entry Registration"
and "- Definitive Securities". All securities offered by this prospectus and the
related prospectus supplement will be rated in one of the four highest rating
categories by one or more nationally recognized statistical rating agencies.

PRINCIPAL AND INTEREST ON THE SECURITIES

         The timing and priority of payment, seniority, allocations of losses,
interest rate and amount of or method of determining payments or distributions
of principal and interest on each class of securities of a given trust will be
described in the related prospectus supplement. The right of holders of any
class of securities to receive payments or distributions of principal and
interest may be senior or subordinate to the rights of holders of any other
class or classes of securities of that series, as described in the related
prospectus supplement. Payments of interest on the securities of that series may
be made prior to payments of principal thereon.

         STRIP SECURITIES AND RESIDUAL INTEREST INSTRUMENTS. If so provided in
the related prospectus supplement, a series may include one or more classes
securities that are:

          -    strip notes or strip certificates entitled to principal payments
               with disproportionate, nominal or no interest payments;



                                       22

<PAGE>   28

          -    strip notes or strip certificates entitled to interest payments
               with disproportionate, nominal or no principal payments; and

          -    residual interest instruments entitled to all or a portion of any
               remaining payments of principal and interest on the related
               contracts after making all other distributions on each
               distribution date.

         INTEREST RATES. Each class of securities may have a different interest
rate, which may be a fixed, variable or adjustable rate, or any combination
thereof. For certain classes of strip securities, the interest rate may be zero.
The related prospectus supplement will specify the interest rate for each class
of securities of a given series or the method for determining the interest rate.

         PREPAYMENT OF SECURITIES. One or more classes of securities of a series
may be redeemable in whole or in part under the circumstances specified in the
related prospectus supplement, including as a result of the servicer's
exercising its option to purchase the remaining related Contracts.

         PRIORITY. In the case of a series of securities which includes two or
more classes of securities, the sequential order and priority of payments or
distributions of principal and interest, and any schedule or formula or other
provisions applicable to the determination thereof, will be set forth in the
related prospectus supplement. Payments or distributions of principal and
interest of any class of securities will be made on a pro rata basis among all
the securityholders of that class.

BOOK-ENTRY REGISTRATION

         We expect that the securities of each series will be issued in
uncertificated book-entry form, and will be registered in the name of Cede &
Co., as nominee of The Depository Trust Company, commonly known as DTC in the
United States and Cedelbank, societe anonyme or the Euroclear System in Europe.
The securities will be tradeable as home market instruments in both the European
and U.S. domestic markets. Initial settlement and all secondary trades will
settle in same-day funds.

         INITIAL SETTLEMENT OF THE SECURITIES. Investors' interests in the
securities will be represented through financial institutions acting on their
behalf as direct and indirect participants in DTC. As a result, Cedelbank and
Euroclear will hold positions on behalf of their customers or participants
through their respective depositaries, which in turn will hold such positions in
accounts as DTC participants.

         Investors electing to hold their securities through DTC will follow the
settlement practices applicable to U.S. corporate debt obligations. Investor
securities custody accounts will be credited with their holdings against payment
in same-day funds on the settlement date.

         Investors electing to hold their securities through Cedelbank or
Euroclear accounts will follow the settlement procedures applicable to
conventional eurobonds, except that there will be no temporary global security
and no "lock-up" or restricted period. Securities will be credited to the
securities custody accounts on the settlement date against payment in same-day
funds.

         Unless and until definitive securities are issued under the limited
circumstances described in this prospectus or in the related prospectus
supplement, no securityholder will be entitled to receive a


                                       23

<PAGE>   29

physical certificate representing a security. All references in this prospectus
and in the related prospectus supplement to actions by securityholders shall
refer to actions taken by DTC upon instructions from its participants, and all
references in this prospectus and in the related prospectus supplement to
distributions, notices, reports and statements to securityholders shall refer to
distributions, notices, reports and statements to DTC or its nominee as the
registered holder of the securities, as the case may be, for distribution to
holders of securities in accordance with DTC's procedures with respect thereto.

         In the event that any of DTC, Cedelbank or Euroclear should discontinue
its services, the related administrator of each trust would seek an alternative
depository, if available, or cause the issuance of definitive securities to
securityholders or their nominees in the manner described under "- Definitive
Securities" below.

         Except as required by law, none of the administrator, if any, the
applicable trustee or the applicable indenture trustee, if any, will have any
liability for any aspect of the records relating to payments made on account of
beneficial ownership interests of the securities of any trust held by DTC's
nominee, or for maintaining, supervising or reviewing any records relating to
the beneficial ownership interests.

         SECONDARY MARKET TRADING OF THE SECURITIES. Since the purchaser
determines the place of delivery, it is important to establish at the time of
the trade where both the purchaser's and seller's accounts are located to ensure
that settlement can be made on the desired value date.

         Trading between DTC participants. Secondary market trading between DTC
participants will be settled using the procedures applicable to U.S. corporate
debt obligations in same-day funds.

         Trading between Cedelbank customers and/or Euroclear participants.
Secondary market trading between Cedelbank customers or Euroclear participants
will be settled using the procedures applicable to conventional eurobonds in
same-day funds.

         Trading between DTC seller and Cedelbank or Euroclear purchaser. When
securities are to be transferred from the account of a DTC participant to the
account of a Cedelbank customer or a Euroclear participant, the purchaser will
send instructions to Cedelbank or Euroclear through a Cedelbank customer or
Euroclear participant at least one business day prior to settlement. Cedelbank
or Euroclear will instruct the respective depositary, as the case may be, to
receive the securities against payment. Payment will include interest accrued on
the securities from and including the last coupon payment date to and excluding
the settlement date. Payment will then be made by the respective depositary to
the DTC participant's account against delivery of the securities. After
settlement has been completed, the securities will be credited to the respective
clearing system and by the clearing system, in accordance with its usual
procedures, to the Cedelbank customer's or Euroclear participant's account. The
securities credit will appear the next day (European time) and the cash debit
will be back-valued to, and the interest on the securities will accrue from, the
value date, which would be the preceding day when settlement occurred in New
York. If settlement is not completed on the intended value date, that is, the
trade fails, the Cedelbank or Euroclear cash debit will be valued instead as of
the actual settlement date.


                                       24

<PAGE>   30

         Cedelbank customers and Euroclear participants will need to make
available to the respective clearing systems the funds necessary to process
same-day funds settlement. The most direct means of doing so is to pre-position
funds for settlement, either from cash on hand or existing lines of credit, as
they would for any settlement occurring within Cedelbank or Euroclear. Under
this approach, they may take on credit exposure to Cedelbank or Euroclear until
the securities are credited to their accounts one day later.

         As an alternative, if Cedelbank or Euroclear has extended a line of
credit to them, Cedelbank customers or Euroclear participants can elect not to
pre-position funds and allow that credit line to be drawn upon to finance
settlement. Under this procedure, Cedelbank customers or Euroclear participants
purchasing securities would incur overdraft charges for one day, assuming they
cleared the overdraft when the securities were credited to their accounts.
However, interest on the securities would accrue from the value date. Therefore,
in many cases the investment income on the securities earned during that one-day
period may substantially reduce or offset the amount of the overdraft charges,
although this result will depend on each Cedelbank customer's or Euroclear
participant's particular cost of funds.

         Since the settlement is taking place during New York business hours,
DTC participants can employ their usual procedures for sending securities to the
respective depositary for the benefit of Cedelbank customers or Euroclear
participants. The sale proceeds will be available to the DTC seller on the
settlement date. Thus, to the DTC participant a cross-market transaction will
settle no differently than a trade between two DTC participants.

         Trading between Cedelbank or Euroclear seller and DTC purchaser. Due to
time zone differences in their favor, Cedelbank customers and Euroclear
participants may employ their customary procedures for transactions in which
securities are to be transferred by the respective clearing system, through the
respective depositary, to a DTC participant. The seller will send instructions
to Cedelbank or Euroclear through a Cedelbank customer or Euroclear participant
at least one business day prior to settlement. In these cases, Cedelbank or
Euroclear will instruct the respective depositary, as appropriate, to deliver
the bonds to the DTC participant's account against payment. Payment will include
interest accrued on the securities from and including the last coupon payment
date to and excluding the settlement date. The payment will then be reflected in
the account of the Cedelbank customer or Euroclear participant the following
day, and receipt of the cash proceeds in the Cedelbank customer's or Euroclear
participant's account would be back-valued to the value date, which would be the
preceding day, when settlement occurred in New York. Should the Cedelbank
customer or Euroclear participant have a line of credit with its respective
clearing system and elect to be in debit in anticipation of receipt of the sale
proceeds in its account, the back-valuation will extinguish any overdraft
charges incurred over that one-day period. If settlement is not completed on the
intended value date, that is, the trade fails, receipt of the cash proceeds in
the Cedelbank customer's or Euroclear participant's account would instead be
valued as of the actual settlement date.

         Finally, day traders that use Cedelbank or Euroclear and that purchase
securities from DTC participants for delivery to Cedelbank customers or
Euroclear participants should note that these trades would automatically fail on
the sale side unless affirmative action were taken. At least three techniques
should be readily available to eliminate this potential problem:

                                       25

<PAGE>   31

          -    borrowing through Cedelbank or Euroclear for one day, until the
               purchase side of the day trade is reflected in their Cedelbank or
               Euroclear accounts, in accordance with the clearing system's
               customary procedures;

          -    borrowing the securities in the U.S. from a DTC participant no
               later than one day prior to settlement, which would give the
               securities sufficient time to be reflected in their Cedelbank or
               Euroclear account in order to settle the sale side of the trade;
               or

          -    staggering the value dates for the buy and sell sides of the
               trade so that the value date for the purchase from the DTC
               participant is at least one day prior to the value date for the
               sale to the Cedelbank customer or Euroclear participant.

         The securityholders who are not participants, either directly or
indirectly, but who desire to purchase, sell or otherwise transfer ownership of,
or other interest in, securities may do so only through direct and indirect
participants. In addition, securityholders will receive all distributions of
principal and interest from the indenture trustee or the applicable trustee
through the participants who in turn will receive them from DTC. Under a
book-entry format, securityholders may experience some delay in their receipt of
payments, since the payments will be forwarded by the applicable trustee to
DTC's nominee. DTC will forward the payments to its participants which
thereafter will forward them to indirect participants or securityholders. To the
extent the related prospectus supplement provides that book-entry securities
will be issued, the only "noteholder" or "certificateholder," as applicable,
will be DTC's nominee. Securityholders will not be recognized by the applicable
trustee as "noteholders" or "certificateholders" and securityholders will be
permitted to exercise the rights of securityholders only indirectly through DTC
and its participants.

         Under the rules, regulations and procedures creating and affecting DTC
and its operations, DTC is required to make book-entry transfers of securities
among participants on whose behalf it acts with respect to the securities and is
required to receive and transmit distributions of principal and interest on the
securities. Participants and indirect participants with which securityholders
have accounts with respect to their respective securities similarly are required
to make book-entry transfers and receive and transmit the payments on behalf of
their respective securityholders. Accordingly, although securityholders will not
possess their respective securities, the rules provide a mechanism by which
participants 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
securityholder to pledge securities to persons or entities that do not
participate in the DTC system, or otherwise take actions with respect to the
securities, may be limited due to the lack of a physical certificate for the
securities.

         DTC will advise the related administrator of each trust that it will
take any action permitted to be taken by a securityholder under the related
indenture or trust agreement only at the direction of one or more participants
to whose accounts with DTC the securities are credited. DTC may take conflicting
actions with respect to other undivided interests to the extent that the actions
are taken on behalf of participants whose holdings include the undivided
interests.

         Non-U.S. holders of securities will be subject to U.S. withholding
taxes unless the holders meet certain requirements and deliver appropriate U.S.
tax documents to the securities clearing organizations or their participants.

         THE DEPOSITORIES. 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 Uniform Commercial
Code, and a "clearing agency" registered under the provisions of Section 17A of
the Securities Exchange Act of 1934, as amended. DTC was created to hold
securities for its participants and facilitate the clearance and settlement of
securities transactions between participants through electronic book-entries,
thereby eliminating the need for physical movement of certificates. Participants
include securities brokers and dealers, who may include any of the underwriters
of securities of the trust, banks, trust companies and clearing corporations and
may include other organizations. 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.

         Cedelbank is incorporated under the laws of Luxembourg as a
professional depository. Cedelbank holds securities for its customers and
facilitates the clearance and settlement of securities transactions between
Cedelbank customers through electronic book-entry changes in accounts of
Cedelbank customers, thereby eliminating the need for physical movement of
certificates. Transactions may be settled by Cedelbank in any of 36 currencies,
including United States dollars. Cedelbank provides to its Cedelbank customers,
among other things, services for safekeeping, administration, clearance and
settlement of internationally traded securities and securities lending and
borrowing. Cedelbank interfaces with domestic markets in several countries. As a
professional depository, Cedelbank is subject in Luxembourg to regulation by and
supervision by the Commission for the Supervision of the Financial Sector.
Cedelbank customers are recognized financial institutions around the world,
including underwriters, securities brokers and dealers, banks, trust companies,
clearing corporations and other organizations and may include any of the
underwriters of any trust securities. Indirect access to Cedelbank is also
available to others, such as banks, brokers, dealers and trust companies that
clear through or maintain a custodial relationship with a Cedelbank customer,
either directly or indirectly.

         Euroclear was created in 1968 to hold securities for its participants
and to clear and settle transactions between Euroclear participants through
simultaneous electronic book-entry delivery against payment, thereby eliminating
the need for physical movement of certificates and the risk from transfers of
securities and cash that are not simultaneous.

         The Euroclear system has subsequently been extended to clear and settle
transactions between Euroclear participants and counterparties both in Cedelbank
and in many domestic securities markets. Transactions may be settled in any of
34 currencies. In addition to safekeeping (custody) and securities clearance and
settlement, the Euroclear system includes securities lending and borrowing and
money transfer services. The Euroclear system is operated by the Brussels,
Belgium office of Morgan Guaranty Trust Company of New York under contract with
Euroclear Clearance System, S.C., a Belgian cooperative corporation that
establishes policy on behalf of Euroclear participants. The Euroclear operator
is the Belgian branch of a New York banking corporation which is a member bank
of the Federal Reserve System. As such, it is regulated and examined by the
Board of Governors of the


                                       27

<PAGE>   33

Federal Reserve System and the New York State Banking Department, as well as the
Belgian Banking Commission.

         All operations are conducted by the Euroclear operator and all
Euroclear securities clearance accounts and cash accounts are accounts with the
Euroclear operator. They are governed by the Terms and Conditions Governing Use
of Euroclear and the related Operating Procedures of the Euroclear system and
applicable Belgian law. These govern all transfers of securities and cash, both
within the Euroclear system, and receipts and withdrawals of securities and
cash. All securities in the Euroclear system are held on a fungible basis
without attribution of specific certificates to specific securities clearance
accounts.

         Euroclear participants include banks (including central banks),
securities brokers and dealers and other professional financial intermediaries
and may include any of the underwriters of any trust securities. Indirect access
to the Euroclear system is also available to other firms that clear through or
maintain a custodial relationship with a Euroclear participant, either directly
or indirectly. The Euroclear operator acts under the Terms and Conditions, the
Operating Procedures of the Euroclear system and Belgian law only on behalf of
Euroclear participants and has no record of or relationship with persons holding
through Euroclear participants.

DEFINITIVE SECURITIES

         With respect to any class of notes and any class of certificates issued
in book-entry form, the notes and certificates will be issued as definitive
securities in fully registered, certificated form to noteholders or certificate
holders or their respective nominees, rather than to DTC or its nominee, only
if:

          -    the seller, the related trustee or the administrator, as the case
               may be, advises the trustee in writing that DTC is no longer
               willing or able to discharge properly its responsibilities as
               depositary with respect to the securities, and the seller, the
               related trustee or the administrator is unable to locate a
               qualified successor;

          -    the seller, the related trustee or the administrator, as the case
               may be, at its option, elects to terminate the book-entry system
               through DTC; or

          -    after the occurrence of an event of default under the indenture,
               if applicable, or an event of default under the related sale and
               servicing agreement or pooling and servicing agreement, as
               applicable, holders representing at least a majority of the
               outstanding principal balance of the notes or certificates of a
               class, as the case may be, advise the applicable trustee through
               participants in writing that the continuation of a book-entry
               system through DTC, or a successor thereto, with respect to those
               notes or certificates is no longer in the best interest of the
               holders of those securities.

         Upon the occurrence of any of the events described in the immediately
preceding paragraph, the applicable trustee will be required to notify all
applicable securityholders of a given class, through participants, of the
availability of definitive securities. Upon surrender by DTC of the definitive
certificates representing the corresponding securities and receipt of
instructions for re-registration, the

                                       28

<PAGE>   34

applicable trustee will reissue the securities as definitive securities, and
thereafter the applicable trustee will recognize the holders of the definitive
securities as securityholders.

         Payments or distributions of principal of and interest on the
securities will be made by the paying agent directly to holders of definitive
securities in accordance with the procedures set forth in this prospectus and in
the related indenture or the related trust agreement or pooling and servicing
agreement, as applicable. Such payments or distributions on each distribution
date and on the final distribution date, as specified in the related prospectus
supplement, will be made to holders in whose names the definitive securities
were registered at the close of business on the related record date. Payments or
distributions will be made by check mailed to the address of the holder as it
appears on the register maintained by the applicable trustee or indenture
trustee. The final payment or distribution on any security, whether definitive
securities or the securities registered in the name of DTC's nominee, however,
will be made only upon presentation and surrender of the security at the office
or agency specified in the notice of final payment or distribution to
securityholders.

         Definitive securities will be transferable and exchangeable at the
offices of the applicable trustee or indenture trustee, or at the offices of a
transfer agent or registrar named in a notice delivered to holders of definitive
securities, which shall initially be the applicable trustee or indenture
trustee. No service charge will be imposed for any registration of transfer or
exchange, but the applicable trustee, indenture trustee, transfer agent or
registrar may require payment of a sum sufficient to cover any tax or other
governmental charge imposed in connection therewith.

LIST OF SECURITYHOLDERS

         With respect to the notes of any series, upon written request of the
servicer, the related indenture trustee will provide to the servicer, the seller
and the security insurer, if any, within 15 days after receipt of the request
from the servicer, seller or security insurer, if any, a list of the names and
addresses of all holders of record of notes as of the most recent record date.
Upon written request by three or more noteholders of the series or by
noteholders evidencing not less than 25% of the aggregate outstanding principal
balance of the notes or a specified class of the notes, as set forth in the
related prospectus supplement, the indenture trustee will afford the noteholders
access during business hours to the current list of noteholders for purposes of
communicating with other noteholders with respect to their rights under the
indenture or under the notes.

         With respect to the certificates of any series upon written request of
the servicer, the related trustee will provide to the servicer within 15 days
after receipt of the request a list of the names and addresses of all holders of
record of certificates as of the most recent record date. Upon written request
by three or more certificateholders of the series or by certificateholders
evidencing not less than 25% of the aggregate outstanding principal balance of
the certificates, the related trustee will afford the 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 related trust agreement or pooling and servicing agreement or under the
certificates.

         The pooling and servicing agreement, trust agreement and indenture will
not provide for the holding of annual or other meetings of securityholders.

              DESCRIPTION OF THE TRANSFER AND SERVICING AGREEMENTS


         The following summary, together with the information set forth in the
related prospectus supplement, describes the material terms of the following
transfer and servicing agreements:


          -    each sale and servicing agreement or pooling and servicing
               agreement under which a trust will purchase contracts from the
               seller and the servicer will agree to service the contracts;

          -    each trust agreement or, in the case of a grantor trust, the

SALE AND ASSIGNMENT OF THE CONTRACTS

         SALE AND ASSIGNMENT BY ONYX AND ITS SUBSIDIARIES. Before each trust
issues the related securities, Onyx and its participating subsidiaries will sell

related financed vehicles. Each contract will be identified in a schedule
appearing as an exhibit to the sale and servicing agreement or pooling and
servicing agreement. The applicable trustee will, concurrently with the sale and

               contains customary and enforceable provisions such that the
               rights and remedies of the holder thereof shall be adequate for

          -    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;

          -    as of the closing date, 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


                                       32

<PAGE>   38

               necessary action with respect to the 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;

          -    as of the closing date, 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;

          -    as of the closing date, 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;

          -    as of the closing date, 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 any contract;

          -    except for payment defaults continuing for a period of not more
               than 30 days as of the cut-off date, 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;

          -    each contract requires that the obligor thereunder obtain
               comprehensive and collision insurance covering the financed
               vehicle;

          -    each contract was acquired from a dealer with whom Onyx
               ordinarily does business, except for contracts purchased or
               originated by a subsidiary of Onyx;

          -    no adverse selection procedures were utilized in selecting the
               contracts;

          -    scheduled payments under each contract have been applied in
               accordance with the method for allocating principal and interest
               set forth in the contract; and

          -    there is only one original of each contract and the original is
               being held by Onyx, the applicable trustee or indenture trustee,
               or the custodian of the contracts specified in the related
               prospectus supplement.

         SELLER MUST REPURCHASE THE CONTRACTS RELATING TO A BREACH OF A
REPRESENTATION OR WARRANTY. As of the last day of the collection period
following the collection period (or, if the seller elects, the last day of the
collection period) during which the seller becomes aware or receives written
notice from the applicable trustee or the servicer of a breach of any
representation or warranty of the seller that materially and adversely affects
the interests of the securityholders or any applicable security insurer in a
contract, the seller, unless the breach has been cured, will repurchase the
contract from the trust at the price specified in the related prospectus
supplement. The repurchase obligation will constitute the sole remedy available
to the securityholders or the applicable trustee for any uncured breach.


                                       33

THE COLLECTION ACCOUNT AND ELIGIBLE INVESTMENTS

         With respect to each trust, the servicer will establish and maintain a
collection account in the name of the related trustee or, in the case of a
series of securities that includes notes, the related indenture trustee, into
which all collections made on the related contracts will be deposited. Funds in
the collection account will be invested in eligible investments by the
applicable trustee or indenture trustee, acting at the direction of any
applicable security insurer. "Eligible investments" are generally limited to
investments acceptable to each rating agency rating the applicable securities as
being consistent with the rating of the securities. Eligible investments made
with respect to the collection account will generally mature no later than the
next following distribution date, and 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

         If so provided in the related prospectus supplement, the servicer will
establish for each trust a payahead account in the name of the related trustee
or indenture trustee, as applicable. Payaheads will initially be deposited in
the collection account and subsequently transferred from the collection account
to the payahead account on the servicer report date defined in the related
prospectus supplement. "Payaheads" are payments made by an obligor, other than
full prepayments, in excess of the sum of:

          -    the scheduled payment of principal and interest due on the
               current due date; and

          -    any other amount currently due on an actuarial or rule of 78's
               contract.

Deposits of payaheads into the payahead account will be held in the account
until distributed in accordance with the original schedule of payments for the
related contract or until the amount of the payahead equals the amount the
obligor would be required to pay in order to prepay the contract in full. Unless
otherwise provided in the related prospectus supplement, amounts on deposit in
the payahead account will be invested in eligible investments with maturity
dates so that, on each distribution date, the amount of principal and interest
scheduled to be collected for each actuarial or rule of 78's contract with
respect to which a payahead has been made will be available to be paid or
distributed to securityholders. The payahead account will not be part of the
applicable trust and neither the related trustee nor the related indenture
trustee, if applicable, will have a security interest in the payahead account.
Earnings on eligible investments credited to the payahead account will be paid
to the servicer.

OTHER ACCOUNTS

         Any other trust accounts to be established with respect to a trust,
including any reserve fund, will be described in the related prospectus
supplement. For any series of securities, funds in any related reserve fund and
the other trust account as may be identified in the related prospectus
supplement will be invested in eligible investments as provided in the related
sale and servicing agreement, pooling and servicing agreement or indenture.

COLLECTIONS

         With respect to each trust, to the extent set forth in the related
prospectus supplement, net 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. Net collections with respect to a
distribution date and the related collection period will include:

          -    amounts received with respect to the related contracts in the
               collection period representing monthly installments of principal
               and interest;

          -    full prepayments and partial prepayments, pending transfer of
               payaheads on actuarial and rule of 78's contracts to any payahead
               account;

          -    net liquidation proceeds - proceeds received by the servicer upon
               liquidation of any defaulted contract, net of the reasonable
               out-of-pocket expenses, other than overhead expenses, incurred by
               the servicer in realizing upon a defaulted contract that are not
               recoverable under any insurance policy;

          -    net insurance proceeds - proceeds paid by any insurer under a
               comprehensive and collision insurance policy related to a
               contract after reimbursement to the servicer of expenses
               recoverable under the policy, but not including funds used for
               the repair of the related financed vehicle or otherwise released
               to the related obligor in accordance with normal servicing
               procedures;

          -    any amounts deposited by Onyx or the seller in the collection
               account to purchase contracts because of breaches of
               representations or warranties regarding the contracts made by the
               seller in the pooling and servicing agreement or sale and
               servicing agreement that materially and adversely affect the
               interests of the securityholders or any security insurer;

          -    any amounts deposited by the servicer in the collection account
               to purchase contracts as to which the servicer has breached
               servicing covenants; and

          -    any amounts deposited by the servicer in the collection account
               as a result of that entity exercising its right under particular
               circumstances to purchase all or a portion of the contracts.

PAYMENTS AND DISTRIBUTIONS

         With respect to each series of securities, beginning on the
distribution date specified in the related prospectus supplement, payments and
distributions of principal and interest (or, where applicable, of principal or
interest only) on each class of the securities entitled thereto will be made by
the applicable trustee to the securityholders of the series. The related
prospectus supplement will set forth the timing, calculation, allocation, order,
source, priorities of and requirements for all payments and distributions to
each class of securities of the series.



                                       35

<PAGE>   41

         With respect to each trust, on each distribution date, collections on
the related contracts will be withdrawn from the related collection account and
will be paid and distributed to the securityholders as provided in the related
prospectus supplement. Credit enhancement will be available to cover any
shortfalls in the amount available for payment or distribution to the
securityholders on the distribution date to the extent specified in the related
prospectus supplement. If specified in the related prospectus supplement,
payments or distributions in respect of one or more classes of securities of the
applicable series may be subordinate to payments or distributions in respect of
one or more other classes of securities of the series.

CREDIT AND CASH FLOW ENHANCEMENT

         The amounts and types of any credit and cash flow enhancement
arrangements and the provider thereof, if applicable, with respect to each class
of Securities of a given series, if any, will be set forth in the related
prospectus supplement. If and to the extent provided in the related prospectus
supplement, credit and cash flow enhancement may be in one or more of the
following forms:

          -    subordination of one or more classes of securities;

          -    one or more security insurance policies;

          -    reserve funds;

          -    over-collateralization;

          -    letters of credit;

          -    credit or liquidity facilities;

          -    guaranteed investment contracts;

          -    swaps or other interest rate protection agreements;

          -    repurchase obligations;

          -    yield supplement agreements;

          -    other agreements with respect to third party payments or other
               support; or

          -    cash deposits; or

          -    such other arrangements as may be described in the related
               prospectus supplement.

         If specified in the applicable prospectus supplement, credit or cash
flow enhancement for a class of securities may cover one or more other classes
of securities of the same series, and credit or cash flow enhancement for a
series of securities may cover one or more other series of securities.

                                       36

<PAGE>   42

         The presence of credit enhancement for the benefit of any class or
series of securities is intended to enhance the likelihood of receipt by the
securityholders of that class or series of the full amount of principal and
interest due thereon and to decrease the likelihood that such securityholders
will experience losses. Unless otherwise specified in the related prospectus
supplement, the credit enhancement for a class or series of securities will not
provide protection against all risks of loss and will not guarantee repayment of
the entire principal balance and interest thereon. If losses occur which exceed
the amount covered by any credit enhancement or which are not covered by any
credit enhancement, securityholders of any class or series will bear their
allocable share of deficiencies, as described in the related prospectus
supplement. In addition, if a form of credit enhancement covers more than one
class or series of securities, securityholders of any of those series will be
subject to the risk that the credit enhancement will be exhausted by the claims
of securityholders of other classes or series.

INSURANCE ON FINANCED VEHICLES

         Each obligor on a contract will be required to maintain insurance
covering physical damage to his or her financed vehicle in an amount not less
than the lesser of its maximum insurable value or the unpaid principal balance
under the contract. Onyx or the applicable Onyx subsidiary will be required to
be named as a loss payee under the policy of insurance obtained by the obligor.
Each financed vehicle will be required to be insured against loss and damage due
to fire, theft, transportation, collision and other risks covered by
comprehensive coverage. Since obligors may choose their own insurers to provide
the required coverage, the specific terms and conditions of their policies vary.

SERVICER REPORTS TO THE TRUSTEES AND SECURITY INSURER

         The servicer will perform certain monitoring and reporting functions
for the applicable indenture trustee, if any, the applicable trustee, and any
applicable security insurer, including the preparation and delivery on the
servicer report date set forth in the related prospectus supplement of a
statement setting forth substantially the same information as is required to be
provided in the periodic reports provided to securityholders of the trust
described under "Description of the Securities - Statements to Securityholders".

REPURCHASE OF CONTRACTS

         Each sale and servicing agreement and pooling and servicing agreement
will provide that the servicer will have the option to purchase the remaining
contracts included in the trust property of a trust on any distribution date as
of which the aggregate principal balance of the related contracts, after giving
effect to the principal payments and distributions otherwise to be made on that
distribution date, has declined to the percentage of the original aggregate
cut-off date principal balance of the contracts specified in the related
prospectus supplement. Any such purchase must be effected at the price specified
in the related prospectus supplement, if applicable, plus all amounts due to any
applicable security insurer. In addition, Onyx or the seller will be required to
purchase or repurchase, respectively, contracts under particular circumstances
if representations and warranties made by Onyx or the seller respectively are
incorrect in any manner that materially and adversely affects the interest of
the securityholders. Additionally, the servicer will be required to purchase
contracts as to which the servicer has breached servicing covenants.


                                       37

SERVICING FEE

         The servicer will be entitled to compensation as described in the
related prospectus supplement for the performance of its obligations under each
sale and servicing agreement and pooling and servicing agreement.

WAIVERS AND EXTENSIONS

         Each sale and servicing agreement and pooling and servicing agreement
will require the servicer to use its best efforts to collect all payments called
for under the terms and provisions of the related contracts. The related
prospectus supplement may provide otherwise, but if it does not, the servicer
will be permitted, in its discretion, to:

          -    waive any late payment charges in connection with delinquent
               payments on a contract;

          -    waive prepayment charges; and

          -    grant up to three extensions of 30 days or less in order to work
               out a default or an impending default.

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. Liquidation may be through repossession or
sale of the financed vehicle securing the contract or otherwise. In connection
with the repossession or other conversion, the servicer will follow procedures
that are normal and usual for holders of motor vehicle retail installment sales
contracts or installment loan agreements. In this regard, the servicer may sell
the financed vehicle at an auction or other sale.

EVIDENCE AS TO COMPLIANCE

         Each sale and servicing agreement and pooling and servicing agreement
will provide that a firm of independent public accountants will furnish to the
related trustee or indenture trustee, as applicable, and, if applicable, the
related security insurer, on or before each March 15 after the end of each
fiscal year of the servicer, a statement as to compliance by the servicer during
the preceding fiscal year with particular standards relating to the servicing of
the related contracts.

         Each sale and servicing agreement and pooling and servicing agreement
will also provide for delivery to the related trustee or indenture trustee, as
applicable, and, if applicable, the related security insurer, on each March 15
after the end of each fiscal year of the servicer, of a certificate signed by an
authorized officer of the servicer stating that the servicer has fulfilled its
obligations under the sale and servicing agreement or pooling and servicing
agreement, as applicable, throughout the preceding fiscal year or, if there has
been a default in the fulfillment of any such obligation, describing each
default.

         Copies of these statements and certificates may be obtained by
securityholders by a request in writing addressed to the applicable trustee or
indenture trustee.

                                       38

<PAGE>   44

CERTAIN MATTERS REGARDING THE SERVICER

         Each sale and servicing agreement and pooling and servicing 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
its duties is no longer permissible under applicable law. No resignation will
become effective until the related trustee or indenture trustee, as applicable,
or a successor servicer, has assumed the servicer's servicing obligations and
duties under the sale and servicing agreement or pooling and servicing
agreement, as applicable. See "- The Trustee and Indenture Trustee" in this
prospectus.

          Each sale and servicing agreement and pooling and servicing agreement
will further provide that neither the servicer nor any of its directors,
officers, employees, and agents shall be under any liability to the related
trust or the related securityholders for taking any action or for refraining
from taking any action under the sale and servicing agreement or pooling and
servicing agreement, as applicable, 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 sale and servicing agreement or pooling and servicing agreement,
as applicable, 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 sale and servicing agreement or
pooling and servicing agreement, as applicable, 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
sale and servicing agreement or pooling and servicing agreement, as applicable,
and the rights and duties of the parties thereto and the interests of the
securityholders thereunder. In this event, the legal expenses and costs of this
action and any liability resulting therefrom will be expenses, costs and
liabilities of the related trust, and the servicer will be entitled to be
reimbursed therefor out of the collection account. This indemnification or
reimbursement could reduce the amount otherwise available for distribution to
securityholders.

         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 sale and servicing agreement or
pooling and servicing agreement, as applicable.

SERVICER DEFAULT

         The related prospectus supplement may provide for other events of
default by the servicer, but if it does not, a servicer default under the sale
and servicing agreement or pooling and servicing agreement, as applicable, will
consist of:

          -    any failure by the servicer to deposit in or credit to the
               collection account or the payahead account, if any, any amount
               required to be so deposited or credited, which failure continues
               unremedied for a period of three business days after written
               notice is received by the servicer from the trust, the applicable
               trustee or indenture trustee, or, if applicable, the related
               security insurer, or after discovery of the failure by an officer
               of the servicer;

                                       39

<PAGE>   45

          -    any failure by the servicer to timely deliver to the trust, the
               applicable trustee or indenture trustee, or, if applicable, the
               related security insurer, reports required by the sale and
               servicing agreement or pooling and servicing agreement, as
               applicable;

          -    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 sale and servicing agreement
               or pooling and servicing agreement, which failure materially and
               adversely affects the rights of securityholders, the trust or the
               applicable trustee or indenture trustee, or, if applicable, the
               related security insurer, and which continues unremedied for 30
               days after the giving of written notice of the failure:

               -    to the servicer or the seller, as the case may be, by the
                    applicable trustee or indenture trustee, the trust, or, if
                    applicable, the related security insurer, or

               -    to the servicer or the seller, as the case may be, and to
                    the trust and the applicable trustee or indenture trustee,
                    by:

                    -    the holders of notes evidencing not less than 25% of
                         the outstanding principal amount of the notes;

                    -    if there are no notes outstanding, the holders of
                         certificates evidencing not less than 25% of the
                         outstanding principal balance of the certificates; or

                    -    if applicable, the related security insurer;

          -    events of insolvency, readjustment of debt, marshalling of assets
               and liabilities, or similar proceedings and actions by the
               servicer or the seller, indicating its insolvency, reorganization
               through bankruptcy or similar proceedings or inability to pay its
               obligations, as more particularly described in the pooling and
               servicing agreement or sale and servicing agreement;

          -    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 related securityholders or,
               if applicable, the related security insurer, and which continues
               for 30 days after the giving of notice of the breach to the
               seller or the servicer, as the case may be, by:

               -    the trust, the applicable trustee or the indenture trustee;

               -    the holders of notes evidencing not less than 25% of the
                    outstanding principal amount of the notes;

<PAGE>   46

               -    if there are no notes outstanding, the holders of
                    certificates evidencing not less than 25% of the outstanding
                    principal balance of the certificates; or

               -    if applicable, the related security insurer;

          -    any change in control of the servicer in violation of the
               covenants set forth in the sale and servicing agreement or
               pooling and servicing agreement.

References to the seller in the foregoing list of events which constitute
servicer defaults are effective only so long as Onyx is the servicer. If Onyx is
no longer the servicer, then no act of the seller will constitute a servicer
default.

RIGHTS UPON SERVICER DEFAULT

         The related prospectus supplement may specify other rights in the event
a servicer default under a sale and servicing agreement or pooling and servicing
agreement, but if it does not, then the trustee, the indenture trustee, if
applicable, the security holders and the security insurer, if any, will have the
rights described below.

         In the case of any trust that has issued notes, as long as a servicer
default under a sale and servicing agreement remains unremedied, the related
indenture trustee, the related security insurer, if any, or holders of notes of
the related series evidencing not less than 25% of principal amount of the notes
then outstanding, acting together as a single class, may terminate all the
rights and obligations of the servicer under the sale and servicing agreement.
Upon termination of the servicer, the indenture trustee or a successor servicer
appointed by the indenture trustee will succeed to all the responsibilities,
duties and liabilities of the servicer under the sale and servicing agreement
and will be entitled to similar compensation arrangements; provided, however,
that the indenture trustee will not be obligated to purchase contracts if
specific representations and warranties of Onyx as servicer prove incorrect or
if specific covenants of Onyx as servicer are breached.

         In the case of any trust that has not issued notes or with respect to
which no notes are outstanding, as long as a servicer default under the related
sale and servicing agreement or pooling and servicing agreement remains
unremedied, the related trustee, the related security insurer, if any, or
holders of certificates of the related series evidencing not less than 25% of
the principal amount of the certificates then outstanding, acting together as a
single class, may terminate all the rights and obligations of the servicer under
the sale and servicing agreement or pooling and servicing agreement. Upon
termination of the servicer, the trustee or a successor servicer appointed by
the trustee will succeed to all the responsibilities, duties and liabilities of
the servicer under the sale and servicing agreement or pooling and servicing
agreement and will be entitled to similar compensation arrangements; provided,
however, that the trustee will not be obligated to purchase contracts if
specific representations and warranties of Onyx as servicer prove incorrect or
if specific covenants of Onyx as servicer are breached.

         In the event that the indenture trustee or trustee is unwilling or
unable to so act, it may appoint, 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 automobile and/or light duty
truck receivables.

WAIVER OF SERVICER DEFAULT

         The related prospectus supplement may specify other waiver provisions,
but if it does not, then with respect to each trust that has issued notes, the
holders of notes of the related series evidencing not less than 51% of the
principal amount of the notes then outstanding, acting together as a single
class, with the consent of the related security insurer, if any, may, on behalf
of all securityholders of the related series, waive any default by the servicer
in the performance of its obligations under the related sale and servicing
agreement and its consequences, except a servicer default in making any required
deposits to or payments from any of the trust accounts in accordance with the
sale and servicing agreement.

         The related prospectus supplement may specify other waiver provisions,
but if it does not, then with respect to each trust that has not issued notes or
with respect to which no notes are then outstanding, holders of certificates of
the related series evidencing not less than 51% of the principal amount of the
certificates then outstanding, acting together as a single class, with the
consent of the related security insurer, if any, may, on behalf of all the
certificateholders, waive any default by the servicer in the performance of its
obligations under the related sale and servicing agreement or pooling and
servicing agreement, except a servicer default in making any required deposits
to or payments from the related trust accounts in accordance with the sale and
servicing agreement or pooling and servicing agreement. No waiver will impair
the noteholders' or certificateholders' rights with respect to subsequent
defaults.

         The related prospectus supplement may specify other waiver provisions,
but if it does not, then a servicer default in making any required deposits to
or payment from the related trust accounts in accordance with the sale and
servicing agreement may only be waived with the consent of the holders of 100%
of the outstanding principal amount of the notes or, if the notes have been paid
in full, the holders of 100% of the outstanding principal amount of the
certificates.

NONPETITION COVENANT

         With respect to each trust, the applicable trustee or indenture trustee
will be under no obligation to exercise any of the trusts or powers vested in it
by the sale and servicing agreement or pooling and servicing agreement, as
applicable, 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 of any of the securityholders, unless the
securityholders have offered to the trustee or indenture trustee reasonable
security or indemnity against the costs, expenses and liabilities which they may
incur under those agreements. No securityholder will have any right under the
sale and servicing agreement or the pooling and servicing agreement to institute
any proceeding with respect the agreement unless:

          -    the holder previously has given to the trustee or indenture
               trustee, as applicable, written notice of default; and

          -    in the case of a trust that has issued notes, holders of notes of
               the related series evidencing not less than 25% of the principal
               amount of the notes then outstanding have made written request
               upon the trustee or indenture trustee to institute the proceeding
               in its own name as trustee or indenture trustee thereunder and
               have offered to the trustee or indenture trustee reasonable
               indemnity;

                                       42

<PAGE>   48

          -    in the case of a trust that has not issued notes or with respect
               to which no notes are then outstanding, holders of certificates
               of the related series evidencing not less than 25% of the
               principal amount of the certificates then outstanding have made
               written request upon the trustee or indenture trustee to
               institute the proceeding in its own name as trustee or indenture
               trustee thereunder and have offered to the trustee or indenture
               trustee reasonable indemnity; and

          -    the related security insurer, if any, consents to the institution
               of the proceeding.

AMENDMENT

         The related prospectus supplement may provide other provisions for the
amendment of the transfer and servicing agreements, but if it does not, then
each of the transfer and servicing agreements may be amended by the parties to
those agreements, without the consent of the related securityholders, but with
the consent of the related security insurer, if any, to cure any ambiguity,
correct or supplement any provisions in the agreement which may be inconsistent
with any other provisions in the agreement, or make any other provisions with
respect to matters or questions arising thereunder which are not inconsistent
with the provisions of the transfer and servicing agreement being amended;
provided that the amendment will not materially and adversely affect the
interest of any securityholder, including, in the case of a trust agreement, any
residual interestholder. Any amendment will be deemed not to materially and
adversely affect the interest of any securityholder if the person requesting the
amendment obtains:

          -    a letter from each rating agency to the effect that the amendment
               would not result in a downgrading or withdrawal of the ratings
               then assigned to the applicable securities by the rating agency;
               or

          -    an opinion of counsel to that effect.

         In the case of a trust agreement, any amendment will be deemed not to
materially and adversely affect the interest of any residual interestholder if:

          -    the person requesting the amendment obtains an opinion of counsel
               to the effect that the amendment will not materially and
               adversely affect the interest of any residual interestholder; or

          -    100% of the residual interestholders consent to the amendment.

         The related prospectus supplement may provide other amendment
provisions, but if it does not, then the transfer and servicing agreements may
also be amended by the parties to those agreements with the consent of the
related security insurer, if any, and the consent of:

          -    in the case of a trust that has issued notes, the holders of
               notes of the related series evidencing not less than 51% of the
               principal amount of the notes then outstanding, acting together
               as a single class; or


                                       43

<PAGE>   49

          -    in the case of a trust that has not issued notes or with respect
               to which no notes are then outstanding, the holders of
               certificates of the related series evidencing not less than 51%
               of the principal amount of the certificates then outstanding,
               acting together as a single class; and

          -    if the amendment materially and adversely affects the interests
               of the residual interestholders, the holders of 51% of the
               residual interest in the trust.

for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of the transfer and servicing agreements or of
modifying in any manner the rights of the noteholders or certificateholders.

         However, without the consent of the holders of all of the outstanding
notes or certificates of the related series, as the case may be, no amendment
may:

          -    increase or reduce in any manner the amount of, or accelerate or
               delay the timing of, collections of payments on the related
               contracts or distributions that are required to be made for the
               benefit of the noteholders, certificateholders or, in the case of
               an amendment to a trust agreement, the residual interestholders;
               or

          -    reduce the percentage of the notes, certificates or, in the case
               of an amendment to a trust agreement, the residual interests of
               that series which are required to consent to any amendment.

TERMINATION

         The related prospectus supplement may specify other termination
provisions, but if it does not, then with respect to each trust, the obligations
of the seller, the servicer, the related trustee and the related indenture
trustee, if any, under the transfer and servicing agreements will terminate upon
the earlier of:

          -    the maturity or other liquidation of the last related contract
               and the disposition of any amounts received upon liquidation of
               any remaining contracts that are part of the related trust
               property; and

          -    the occurrence of all of the following:

               -    the payment to noteholders, if any, and certificateholders
                    of the related series of all amounts required to be paid to
                    them under the transfer and servicing agreements and the
                    disposition of all property held as part of the related
                    trust;

               -    if applicable, the termination of the related security
                    insurance policy in accordance with its terms and the
                    surrender of the policy to the related security insurer for
                    cancellation;

                                       44

<PAGE>   50

               -    the payment of all amounts owed to the trustee or indenture
                    trustee under the transfer and servicing agreements; and

               -    if applicable, the payment of all amounts owed to the
                    related security insurer in connection with the related
                    security insurance policy.

         If so provided in the related prospectus supplement, in order to avoid
excessive administrative expense, the servicer will be permitted at its option
to purchase the remaining contracts included in the trust property of a trust on
any distribution date as of which the aggregate outstanding principal balance of
the related contracts, after giving effect to the principal payments and
distributions otherwise to be made on that date, has declined to the percentage
of the aggregate cut-off date principal balance of the contracts specified in
the related prospectus supplement at the price specified in the related
prospectus supplement and, if applicable, all amounts due to the related
security insurer in connection with the related security insurance policy. The
applicable trustee or indenture trustee will give written notice of termination
to each securityholder of record. The final payment or distribution to any
securityholder will be made only upon surrender and cancellation of the
securityholder's security at an office or agency of the applicable trustee or
indenture trustee specified in the notice of termination. Any funds remaining in
the applicable trust, after the applicable trustee or indenture trustee has
taken measures to locate a securityholder and these measures have failed, will
be distributed to a charity designated by the servicer.

THE TRUSTEE AND INDENTURE TRUSTEE

         With respect to each trust, the applicable trustee or indenture trustee
will not make any representations as to the validity or sufficiency of the
related transfer and servicing agreements, the related indenture, if any, the
securities, or any related contracts or related documents, or the investment of
any monies by the servicer before being deposited in or credited to the related
collection account. At the applicable closing date, the trustee or indenture
trustee will not have examined the contracts. If no event of default has
occurred, the trustee or indenture trustee will be required to perform only
those duties specifically required of it under the related transfer and
servicing agreements or the related indenture, if applicable. Generally, those
duties are limited to:

          -    the receipt of the various certificates, reports or other
               instruments required to be furnished to the trustee or indenture
               trustee under the related transfer and servicing agreements or
               the related indenture, if applicable;

          -    the making of payments or distributions to securityholders in the
               amounts specified in certificates provided by the servicer; and

          -    if applicable, drawing on the related security insurance policy
               if required to make payments or distributions to securityholders.

         Each trustee and indenture trustee, and any of its affiliates, may hold
securities in their own names. In addition, for the purpose of meeting the legal
requirements of local jurisdictions, each trustee and indenture trustee, in some
circumstances acting jointly with the servicer, will have the power to appoint
co-trustees or separate trustees of all or any part of the related trust
property. In this event, all

                                       45

<PAGE>   51

rights, powers, duties and obligations conferred or imposed upon the trustee or
indenture trustee by the related transfer and servicing agreement or indenture,
as applicable, will be conferred or imposed upon the trustee or indenture
trustee and the separate trustee or co-trustee jointly, or, in any jurisdiction
in which the trustee or indenture trustee is incompetent or unqualified to
perform certain acts, singly upon the separate trustee or co-trustee who will
exercise and perform these rights, powers, duties and obligations solely at the
direction of the trustee or indenture trustee.

         The related prospectus supplement may specify other resignation and
removal provisions, but if it does not, then each applicable trustee and
indenture trustee may resign at any time, in which event a successor trustee
will be appointed under the terms of the related transfer and servicing
agreement or indenture, as applicable. Each applicable trustee and indenture
trustee may be removed if it ceases to be eligible to continue as such under the
related transfer and servicing agreement or indenture, as applicable, or if the
trustee or indenture trustee becomes insolvent. Any resignation or removal of
the trustee or indenture trustee and appointment of a successor does not become
effective until acceptance of the appointment by the successor trustee.

         If so provided by the related prospectus supplement, each applicable
trustee or indenture trustee will be entitled to a fee which will be payable on
an annual basis by the servicer. The related prospectus supplement may specify
other indemnification provisions, but if it does not, then the related transfer
and servicing agreement or indenture, as applicable, will further provide that
the trustee or indenture 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 or indenture trustee not resulting from the trustee's or
indenture 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 related transfer and servicing
agreement or indenture, as applicable. However, the servicer will not be
obligated to indemnify the applicable trustee or indenture trustee to the extent
that the loss, liability, or expense relates to a specific contract or contracts
or certain taxes that could be asserted against the trustee or indenture
trustee, the related trust or the related contracts, in which case the trustee
or indenture trustee would be entitled to be indemnified by the applicable
trust.

         Onyx and the seller may maintain other banking relationships with each
applicable trustee or indenture trustee in the ordinary course of business.

ADMINISTRATION AGREEMENT

         With respect to a trust that issues notes, Onyx or another party
specified in the related prospectus supplement, in its capacity as
administrator, may enter into an administration agreement with the trust and the
related indenture trustee under which Onyx, as the administrator will agree, to
the extent provided in the administration agreement, to provide the notices and
to perform other administrative obligations required by the related indenture.
The related prospectus supplement may specify other compensation arrangements
for the administrator, but if it does not, then as compensation for the
performance of the administrator's obligations under the applicable
administration agreement and as reimbursement for its related expenses, the
administrator will be entitled to a monthly administration fee of an amount to
be set forth in the related prospectus supplement, which fee will be paid by the
servicer.

                                  THE INDENTURE

         The following summary describes some of the terms of each indenture
under which the notes, if any, of a series will be issued. A form of indenture
has been filed as an exhibit to the registration statement of which this
prospectus is a part. This summary does not purport to be complete and is
subject to, and qualified in its entirety by reference to, all the provisions of
each applicable indenture and the related prospectus supplement.

MODIFICATION OF INDENTURE

         The related prospectus supplement may provide other provisions for
modification of the related indenture, but if it does not, then the related
indenture may be modified as described below.

         With respect to each trust that has issued notes under an indenture,
the trust and the indenture trustee may, with the consent of the holders of
notes of the related series evidencing not less than 51% of the principal amount
of the notes then outstanding, acting as a single class, and with the consent of
the related security insurer, if any, execute a supplemental indenture to add
provisions to, change in any manner or eliminate any provisions of, the related
indenture, or modify, except as provided below, in any manner the rights of the
related noteholders.

         With respect to a series that includes notes, without the consent of
the holder of each outstanding note affected by a supplemental indenture, no
supplemental indenture may:

          -    change the due date of any installment of principal of or
               interest on a note;

          -    reduce the principal amount of a note;

          -    reduce the interest rate of a note;

          -    reduce the redemption price of a note;

          -    change any place of payment where a note or interest on a note is
               payable;

          -    change the coin or currency in which a note or any interest on a
               note is payable;

          -    impair the right to institute suit for the enforcement of certain
               provisions of the related indenture regarding payment;

          -    reduce the percentage of the aggregate amount of the outstanding
               notes of the series, the consent of the holders of which is
               required for any supplemental indenture or the consent of the
               holders of which is required for any waiver of compliance with
               certain provisions of the related indenture or of certain
               defaults under the related indenture and their consequences as
               provided for in the related indenture;

                                       47

<PAGE>   53

          -    modify or alter the provisions of the related indenture regarding
               the voting of notes held by the applicable trust, any other
               obligor on the notes, the seller or an affiliate of any of them;

          -    reduce the percentage of the aggregate outstanding amount of the
               notes, the consent of the holders of which is required to direct
               the related indenture trustee to sell or liquidate the contracts
               if the proceeds of the sale would be insufficient to pay the
               principal amount and accrued but unpaid interest on the
               outstanding notes of the series;

          -    decrease the percentage of the aggregate principal amount of the
               notes required to amend the sections of the related indenture
               which specify the applicable percentage of aggregate principal
               amount of the notes required to amend the related indenture or
               certain other related agreements; or

          -    permit the creation of any lien ranking prior to or on a parity
               with the lien of the related indenture with respect to any of the
               collateral for the notes or, except as otherwise permitted or
               contemplated in the indenture, terminate the lien of the
               indenture on any of the collateral or deprive the holder of any
               note of the security afforded by the lien of the indenture.

         With respect to a series that includes notes, the related trust and the
applicable indenture trustee may also enter into supplemental indentures,
without obtaining the consent of the noteholders of the related series, but with
the consent of the related security insurer, if any, for the purpose of, among
other things, adding any provisions to or changing in any manner or eliminating
any of the provisions of the related indenture or of modifying in any manner the
rights of the noteholders; provided that this action will not materially and
adversely affect the interest of any noteholder.

INDENTURE EVENTS OF DEFAULT

         The related prospectus supplement may specify other events of default
under the related indenture, but if it does not, then, with respect to the notes
of a given series, the following will constitute indenture events of default:

          -    a draw on any security insurance policy;

          -    a default for five days or more in the payment of any interest on
               any note;

          -    a default in the payment of the principal of or any installment
               of the principal of any note when the same becomes due and
               payable;

          -    a default in the observance or performance of any covenant or
               agreement of the applicable trust made in the related indenture
               and the continuation of the default for a period of 90 days after
               notice is given to the trust by the applicable indenture trustee
               or the related security insurer, if any, or to the trust and the
               indenture trustee by the holders of at least 25% in principal
               amount of the notes then outstanding acting together as a single
               class;

                                       48

<PAGE>   54

          -    any representation or warranty made by the trust in the related
               indenture or in any certificate delivered under or in connection
               with the indenture having been incorrect in a material respect as
               of the time made, and the breach not having been cured within 30
               days after notice thereof is given to the trust by the applicable
               indenture trustee or the related security insurer, if any, or to
               the trust and the indenture trustee by the holders of at least
               25% in principal amount of the notes then outstanding acting
               together as a single class; or

          -    events of bankruptcy, insolvency, receivership or liquidation of
               the applicable trust.

         The related prospectus supplement may specify other default provisions,
but if it does not, and if a security insurance policy is in effect with respect
to the notes, then so long as a default by the insurer shall not have occurred
and be continuing, an indenture event of default will occur only upon delivery
by the security insurer to the indenture trustee of notice of the occurrence of
an indenture event of default. is the security insurer is not in default. The
failure to pay principal on a class of notes generally will not result in the
occurrence of an indenture event of default until the final scheduled
distribution date for that class of notes.

RIGHTS UPON INDENTURE EVENT OF DEFAULT

         The related prospectus supplement may specify other rights upon the
occurrence of an indenture event of default, but if it does not, then the
trustee, the securityholders and the security insurer, if any, will have the
rights described below. The related prospectus supplement will specify those
events which constitute a default by the security insurer, if any.

         NO SECURITY INSURANCE POLICY OR SECURITY INSURER IN DEFAULT. If there
is no security insurance policy with respect to a series of notes, or if a
default by the related security insurer has occurred and is continuing, then
upon the occurrence of an indenture event of default, the holders of at least
66 2/3% of the principal amount of the notes then outstanding may declare that
the notes become immediately due and payable. Also, in this event, the holders
of at least 66 2/3% of the principal amount of the notes then outstanding will
have the right to control the exercise of remedies available with respect to the
indenture event of default, including the right to direct the indenture trustee
to maintain possession of the trust property or to liquidate the trust property
in whole or in part. However, the noteholders may not direct the indenture
trustee to liquidate the trust property in whole or in part unless either:

          -    the security insurer, if any, has failed to make a payment
               required under the security insurance policy, and the indenture
               event of default has occurred because of:

               -    a default in the payment of any principal on the final
                    scheduled distribution date for a class of notes or a
                    default of at least five days in the payment of any interest
                    on any notes; or

               -    events of bankruptcy, insolvency, receivership or
                    liquidation of the trust; or


                                       49

<PAGE>   55

          -    the security insurer, if any, has not failed to make a payment
               required under the security insurance policy, and an indenture
               event of default has occurred other than as described above, and
               either:

               -    the proceeds of the sale will be sufficient to pay all
                    outstanding principal and accrued interest of the notes and
                    the certificates, and all amounts owing to the security
                    insurer, if any; or

               -    holders of certificates evidencing 100% of the outstanding
                    principal amount of the certificates consent to the sale and
                    all amounts owing to the security insurer, if any, will be
                    paid in connection with the sale.

         In the event of a sale of the contracts as described in the second
alternative above when the security insurer has not failed to make a payment
required under a security insurance policy, the security insurance policy will
not be available to cover losses to securityholders resulting from the sale and
will be terminated and the security insurer will have no further obligation to
make any payment thereunder.

         SECURITY INSURANCE POLICY AND NO SECURITY INSURER DEFAULT. Upon the
occurrence of an indenture event of default, so long as a default by the
security insurer shall not have occurred and be continuing, the security insurer
will have the right, but not the obligation, to declare by written notice to the
trust and the indenture trustee that the notes become immediately due and
payable. Upon the occurrence of an indenture event of default, so long as a
default by the security insurer shall not have occurred and be continuing, the
security insurer will have the right to control the exercise of remedies
available with respect to the indenture event of default, including the right to
direct the indenture trustee to maintain possession of the trust property or to
liquidate the trust property in whole or in part, on any date or dates following
the acceleration of the notes due to the indenture event of default as the
security insurer, in its sole discretion, shall elect. The security insurer may
not, however, cause the indenture trustee to liquidate the trust property in
whole or in part if the proceeds of the liquidation would not be sufficient to
pay all outstanding principal of and accrued interest on the notes. Following
the occurrence of any indenture event of default, the trustee and the indenture
trustee will continue to submit claims under the security insurance policy for
any shortfalls in amounts available to make payments or distributions of
guaranteed amounts on the notes and the certificates. However, following the
occurrence of an indenture event of default, so long as a default by the
security insurer shall not have occurred and be continuing, the security
insurer, at its sole option, may elect to pay all or any portion of the
outstanding amount of the notes, plus accrued interest thereon to the date of
payment.

COVENANTS

         RESTRICTIONS ON CONSOLIDATION OR MERGER. The related prospectus
supplement may specify other covenants, but if it does not, then, with respect
to a series that includes notes, each indenture will provide that the related
trust may not consolidate with or merge into any other entity, unless:

          -    the entity formed by or surviving the consolidation or merger is
               organized under the laws of the United States, any state or the
               District of Columbia;

                                       50

<PAGE>   56

          -    the surviving entity expressly assumes the trust's obligation to
               make due and punctual payments upon the notes of the related
               series and the performance or observance of every agreement and
               covenant of the trust under the indenture;

          -    no event of default under the indenture shall have occurred and
               be continuing immediately after the merger or consolidation;

          -    the trust has been advised that the rating of the securities of
               the related series then in effect would not be reduced or
               withdrawn by any rating agency as a result of the merger or
               consolidation; and

          -    the trust has received an opinion of counsel to the effect that
               the consolidation or merger would have no material adverse tax
               consequence to the trust or to any holder of the securities of
               the related series.

         OTHER NEGATIVE COVENANTS. Each trust that has issued notes will not,
among other things:

          -    except as expressly permitted by the applicable indenture, the
               applicable transfer and servicing agreements or certain related
               documents with respect to the trust, sell, transfer, exchange or
               otherwise dispose of any of the assets of the trust;

          -    claim any credit on or make any deduction from the principal and
               interest payable in respect of the notes of the related series,
               other than amounts withheld under the tax code or applicable
               state law, or assert any claim against any present or former
               holder of the notes because of the payment of taxes levied or
               assessed upon the trust;

          -    dissolve or liquidate in whole or in part;

          -    permit the validity or effectiveness of the related indenture to
               be impaired or permit any person to be released from any
               covenants or obligations with respect to the notes under the
               indenture except as may be expressly permitted thereby; or

          -    permit any lien, charge, excise, claim, security interest,
               mortgage or other encumbrance to be created on or extend to or
               otherwise arise upon or burden the assets of the trust or any
               part of the trust, or any interest in the trust or the proceeds
               of the trust.

         No trust that has issued notes will incur, assume or guarantee any
indebtedness other than indebtedness incurred under the related notes and the
related indenture, or otherwise in accordance with the applicable transfer and
servicing agreements and other related documents.

ANNUAL COMPLIANCE STATEMENT

         Each trust that has issued notes will be required to file annually with
the related indenture trustee a written statement as to the fulfillment of its
obligations under the indenture.



                                       51

INDENTURE TRUSTEE'S ANNUAL REPORT

         The indenture trustee for each trust that has issued notes will be
required to mail each year to all related noteholders a brief report relating
to:

          -    its eligibility and qualification to continue as indenture
               trustee under the related indenture;

          -    any amounts advanced by it under the indenture;

          -    the amount, interest rate and maturity date of indebtedness owing
               by the trust to the applicable indenture trustee in its
               individual capacity; and

          -    the property and funds physically held by the indenture trustee
               as such and any action taken by it that materially affects the
               related notes and that has not been previously reported.

SATISFACTION AND DISCHARGE OF INDENTURE

         An indenture will be discharged with respect to the collateral securing
the related notes upon the delivery to the related indenture trustee for
cancellation of all of the related notes or, with certain limitations, upon
deposit with the indenture trustee of funds sufficient for the payment in full
of all of the related notes.

THE INDENTURE TRUSTEE

         The indenture trustee, if applicable, will be specified in the related
prospectus supplement. Under the Trust Indenture Act of 1939, as amended, the
indenture trustee may have a "conflicting interest" if any event of default
under the indenture occurs with respect to a series that includes one or more
classes of notes that are subordinated to any other class of notes. In this
event, the indenture trustee may be required to resign with respect to one or
more classes of notes and the successor indenture trustee would be appointed for
such class or classes of notes. Certain matters relating to the indenture
trustee for each series that includes notes are described under "Description of
the Transfer and Servicing Agreements -- The Trustee and Indenture Trustee" in
this prospectus.


                     CERTAIN LEGAL ASPECTS OF THE CONTRACTS

GENERAL

         The transfer of contracts by Onyx and any of its subsidiaries to the
seller, and by the seller to the applicable trust, and, if applicable, the
pledge of those contracts to an indenture trustee, the perfection of the
security interests in the contracts and the enforcement of rights to realize on
the related financed vehicles as collateral for the contracts are subject to a
number of federal and state laws, including the Uniform Commercial Code, or UCC,
as in effect in various states. The servicer and the seller will take the action
described below to perfect the rights of the applicable trust and, if
applicable, the indenture

                                       52

<PAGE>   58

trustee in the contracts. If, through inadvertence or otherwise, another party
purchases, including the taking of a security interest in, a contract for new
value in the ordinary course of its business, without actual knowledge of the
trust's interest in the contract, and, if applicable, the indenture trustee's
interest in the contract, and takes possession of the contract, the purchaser
would acquire an interest in the contract superior to the interest of the trust
and, if applicable, the interest of the indenture trustee.

         The related prospectus supplement may specify other information
concerning the custody of the contracts, but if it does not, then under each
sale and servicing agreement, pooling and servicing agreement or indenture, as
applicable, Onyx will have custody of the contracts included in the trust
property of a trust following the sale of the contracts to the related trust
and, if applicable, the pledge of those contracts to the related indenture
trustee, and will hold the contracts as custodian for the benefit of the trust
or, if applicable, the indenture trustee. While the contracts will not be
physically marked to indicate the ownership interest thereof by the trust or, if
applicable, the pledge of the contracts to the related indenture trustee,
appropriate UCC-1 financing statements will be filed to perfect by filing and
give notice of the trust's ownership interest in, and, if applicable, the
indenture trustee's security interest in, the contracts. If, through
inadvertence or otherwise, any of the contracts were sold to another party who
purchased the contracts in the ordinary course of its business and took
possession of the contracts, the purchaser would acquire an interest in the
contracts superior to the interests of the trust and, if applicable, the
interests of the indenture trustee, if the purchaser acquired the contracts in
good faith, for value and without actual knowledge of the trust's and, if
applicable, the indenture trustee's, interests in the contracts.

SECURITY INTERESTS IN THE FINANCED VEHICLES

         GENERAL. Retail installment sale contracts and installment loan
agreements like the contracts evidence the credit sale of automobiles, light
duty trucks and vans. The contracts also constitute personal property security
agreements and include grants of security interests in the vehicles under the
applicable UCC. In most states, a security interest in an automobile, light duty
truck or van is perfected by obtaining the certificate of title to the financed
vehicle or notation of the secured party's lien on the vehicle's certificate of
title. The seller will warrant to the related trust in the sale and servicing
agreement or pooling and servicing agreement, as applicable, that Onyx or a
subsidiary of 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 the security interest has been assigned to the trust. If Onyx
fails, because of clerical errors or otherwise, to effect or maintain the
notation of the security interest on the certificate of title relating to a
financed vehicle, the trust may not have a first priority security interest in
the financed vehicle.

         PERFECTION. The seller will sell the contracts and assign the security
interest in each financed vehicle to the related 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 or a
subsidiary of 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 and most other states, 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 related trust as the new secured


                                       53

<PAGE>   59

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
or a subsidiary of Onyx will be sufficient to protect the related 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 or a subsidiary of Onyx has failed to perfect the
security interest assigned to the related trust, the 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 the
relocation and thereafter, in most instances, until the owner re-registers the
financed vehicle in that 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 of 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 or a subsidiary of Onyx,
absent clerical errors or fraud, would receive notice of surrender of the
certificate of title if its lien is noted thereon. Each subsidiary of Onyx named
as the secured party on a certificate of title will agree to promptly forward to
Onyx any notice received by the subsidiary. 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, re-registration could defeat perfection. In the ordinary course of
servicing its portfolio of contracts, Onyx takes steps to effect the
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 or its
subsidiary's lien noted thereon and accordingly will have an opportunity to
require satisfaction of the related contract before release of the lien. Under
the sale and servicing agreement or pooling and servicing agreement, as
applicable, Onyx, at its cost, will be obligated to maintain the continuous
perfection of the security interest of Onyx or its subsidiary in the financed
vehicle.

         Under the laws of most states, including California, certain statutory
liens such as liens for unpaid taxes, liens for towing and storage of and
repairs performed on a motor vehicle, motor vehicle accident liens, and liens
arising under various state and federal criminal statutes take priority even
over a perfected security interest. The tax code also grants priority to certain
federal tax liens over the lien of a secured party. The laws of most states and
federal law permit the confiscation of motor vehicles by governmental
authorities under certain circumstances if used in or acquired with the proceeds
of unlawful activities, which may result in the loss of a secured party's
perfected security interest in a confiscated vehicle. The seller will represent
in each sale and servicing agreement or pooling and servicing agreement, as
applicable, that, as of the initial issuance of the securities of the related
series, no such state or federal liens exist with respect to any financed
vehicle securing payment on any related Contract. However, these liens could
arise, or such a confiscation could occur, at any time during the


                                       54

<PAGE>   60

term of a contract. It is possible that no notice will be given to the servicer
in the event one of these liens arises or a confiscation occurs, and any lien
arising or confiscation occurring after the related closing date would not give
rise to the seller's repurchase obligations under the related sale and servicing
agreement or pooling and servicing agreement, as applicable.

REPOSSESSION

         In the event of default by an obligor, the holder of the related retail
installment sale contract or installment loan agreement has all the remedies of
a secured party under the UCC, except where specifically limited by other state
laws. Among the UCC remedies, the secured party has the right to perform
repossession by self-help means, unless this would constitute a breach of the
peace or is otherwise limited by applicable state law. Unless a financed vehicle
is voluntarily surrendered, self-help repossession is accomplished simply by
retaking possession of the financed vehicle. In cases where the obligor objects
or raises a defense to repossession, or if otherwise required by applicable
state law, a court order must be obtained from the appropriate state court, and
the financed vehicle must then be recovered in accordance with that order. In
some jurisdictions, the secured party is required to notify the obligor of the
default and the intent to repossess the collateral and to give the obligor a
time period within which to cure the default prior to repossession. Generally,
this right of cure may only be exercised on a limited number of occasions during
the term of the related contract. Other jurisdictions permit repossession
without prior notice if it can be accomplished without a breach of the peace,
although in some states, a course of conduct in which the creditor has accepted
late payments has been held to create a right by the obligor to receive prior
notice. In many states, under certain circumstances after the financed vehicle
has been repossessed, the obligor may reinstate the related contract by paying
the delinquent installments and other amounts due.

NOTICE OF SALE; REDEMPTION RIGHTS

         The UCC and other state laws require the secured party to provide the
obligor with reasonable notice of the date, time and place of any public sale
and/or the date after which any private sale of the collateral may be held. In
addition, some states also impose substantive timing requirements on the sale of
repossessed vehicles in certain circumstances and/or various substantive timing
and content requirements on the notices. In some states, under certain
circumstances after a financed vehicle has been repossessed, the obligor may
redeem the collateral by paying the delinquent installments and other amounts
due. The obligor has the right to redeem the collateral prior to actual sale or
entry by the secured party into a contract for sale of the collateral by paying
the secured party the unpaid principal balance of the obligation, accrued
interest thereon, reasonable expenses for repossessing, holding, and preparing
the collateral for disposition and arranging for its sale, plus, in some
jurisdictions, reasonable attorneys' fees and legal expenses or in some other
states, by payment of delinquent installments on the unpaid principal balance of
the related obligation.

DEFICIENCY JUDGMENTS AND EXCESS PROCEEDS

         The proceeds of resale of the repossessed financed vehicles generally
will be applied first to the expenses of resale and repossession and then to the
satisfaction of the indebtedness. While some states impose prohibitions or
limitations on deficiency judgments if the net proceeds from resale do not cover
the full amount of the indebtedness, a deficiency judgment can be sought in
those states that do not

                                       55

<PAGE>   61

prohibit or limit deficiency judgments. In addition to the notice requirement,
the UCC requires that every aspect of the sale or other disposition, including
the method, manner, time, place and terms, be "commercially reasonable."
Generally, courts have held that when a sale is not "commercially reasonable,"
the secured party loses its right to a deficiency judgment.

         In addition, the UCC permits the debtor or other interested party to
recover for any loss caused by noncompliance with the provisions of the UCC.
Also, prior to a sale, the UCC permits the debtor or other interested person to
prohibit the secured party from disposing of the collateral if it is established
that the secured party is not proceeding in accordance with the "default"
provisions under the UCC. Any deficiency judgment would be a personal judgment
against the obligor for the shortfall, and a defaulting obligor can be expected
to have very little capital or sources of income available following
repossession. Therefore, in many cases, it may not be useful to seek a
deficiency judgment or, if one is obtained, it may be settled at a significant
discount or be uncollectible.

         Occasionally, after resale of a repossessed vehicle and payment of all
expenses and indebtedness, there is a surplus of funds. In that case, the UCC
requires the creditor to remit the surplus to any holder of a subordinate lien
with respect to the repossessed vehicle or if no subordinate lienholder exists,
the UCC requires the creditor to remit the surplus to the obligor.

CONSUMER PROTECTION LAWS

         Numerous federal and state consumer protection laws and related
regulations impose substantial requirements upon lenders and servicers involved
in consumer finance. These laws include the Truth-in-Lending Act, the Equal
Credit Opportunity Act, the Federal Trade Commission Act, the Fair Credit
Billing Act, the Fair Credit Reporting Act, the Fair Debt Collection Practices
Act, the Magnuson-Moss Warranty Act, the Federal Reserve Board's Regulations B
and Z, the Soldiers' and Sailors' Civil Relief Act of 1940, state adoptions of
the National Consumer Act and of the Uniform Consumer Credit Code, state motor
vehicle retail installment sales acts, state "lemon" laws and other similar
laws. Also, state laws impose finance charge ceilings and other restrictions on
consumer transactions and require contract disclosures in addition to those
required under federal law. These requirements impose specific statutory
liabilities upon creditors who fail to comply with their provisions. In some
cases, this liability could affect an assignee's ability to enforce consumer
finance contracts such as the contracts.

         The so-called "Holder-in-Due-Course" rule of the Federal Trade
Commission, commonly referred to as the "FTC Rule," has the effect of subjecting
any assignee of the seller in a consumer credit transaction, and certain related
creditors and their assignees, to all claims and defenses which the obligor in
the transaction could assert against the seller. Liability under the FTC Rule is
limited to the amounts paid by the obligor under the contract, and the holder of
the contract may also be unable to collect any balance remaining due thereunder
from the obligor. The FTC Rule is generally duplicated by the Uniform Consumer
Credit Code, other state statutes or the common law in certain states.

         Most of the contracts will be subject to the requirements of the FTC
Rule. Accordingly, each trust, as holder of the related contracts, will be
subject to any claims or defenses that the purchaser of the applicable financed
vehicle may assert against the seller of the financed vehicle. As to each
obligor, these claims are limited to a maximum liability equal to the amounts
paid by the obligor on the related


                                       56

<PAGE>   62

contract. The seller will represent in each sale and servicing agreement or
pooling and servicing agreement, as applicable, that each of the contracts, and
the sale of the related financed vehicle thereunder, complied with all material
requirements of the laws and the regulations issued under the FTC Rule.

         Any shortfalls or losses arising in connection with the matters
described in the two preceding paragraphs, to the extent not covered by amounts
payable to the securityholders from amounts available under a credit enhancement
mechanism, could result in losses to the securityholders.

         Courts have applied general equitable principles to secured parties
pursuing repossession and litigation involving deficiency balances. These
equitable principles may have the effect of relieving an obligor from some or
all of the legal consequences of a default.

         In several cases, consumers have asserted that the self-help remedies
of secured parties under the UCC and related laws violate the due process
protections provided under the 14th Amendment to the Constitution of the United
States. Courts have generally upheld the notice provisions of the UCC and
related laws as reasonable or have found that the repossession and resale by the
creditor do not involve sufficient state action to afford constitutional
protection to borrowers.

OTHER LIMITATIONS

         In addition to the laws limiting or prohibiting deficiency judgments,
numerous other statutory provisions, including federal bankruptcy laws and
related state laws, may interfere with or affect the ability of a secured party
to realize upon collateral or to enforce a deficiency judgment. For example, in
a Chapter 13 proceeding under the federal bankruptcy law, a court may prevent a
creditor from repossessing a vehicle, and, as part of the rehabilitation plan,
reduce the amount of the secured indebtedness to the market value of the vehicle
at the time of bankruptcy, as determined by the court, leaving the creditor as a
general unsecured creditor for the remainder of the indebtedness. A bankruptcy
court may also reduce the monthly payments due under a contract or change the
rate of interest and time of repayment of the indebtedness.

         Under the terms of the Soldiers' and Sailors' Relief Act of 1940, an
obligor who enters the military service after the origination of the obligor's
contract, including an obligor who is a member of the National Guard or is in
reserve status at the time of the origination of the obligor's contract and is
later called to active duty, may not be charged interest above an annual rate of
6% during the period of his or her active duty status, unless a court orders
otherwise upon application of the lender. In addition, under the Military
Reservist Relief Act, under certain circumstances, California residents called
into active duty with the reserves can delay payments on retail installment
sales contracts, including the contracts, for a period, not to exceed 180 days,
beginning with the order to active duty and ending 30 days after release. It is
possible that this could have an effect on the ability of the servicer to
collect the full amount of interest owing on certain of the contracts. In
addition, the Relief Acts impose limitations that would impair the ability of
the servicer to repossess an affected contract during the obligor's period of
active duty status. Thus, in the event that an affected contract goes into
default, there may be delays and losses occasioned by the inability to exercise
the trust's rights with respect to the related financed vehicle in a timely
fashion.

         Any shortfalls or losses arising in connection with the matters
described in the two preceding paragraphs, to the extent not covered by amounts
payable to the securityholders from amounts available under a credit enhancement
mechanism, could result in losses to the securityholders.

REPURCHASE OBLIGATION

         Under each sale and servicing agreement or pooling and servicing
agreement, the seller will make representations and warranties relating to
validity, existence, perfection and priority of the security interest in each
related financed vehicle as of the related closing date. See "Description of the
Transfer and Servicing Agreements - 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 and the defect adversely affects the
related trust's interest in the related contract, the defect would constitute a
breach of a warranty under the sale and servicing agreement or pooling and
servicing agreement, as applicable, and would create an obligation of the seller
to repurchase the contract unless the breach is cured. Additionally, in the sale
and servicing agreement or pooling and servicing agreement, as applicable, 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 related trust unless the breach is
cured.


                     CERTAIN FEDERAL INCOME TAX CONSEQUENCES

         The following general discussion of the anticipated material federal
income tax consequences of the purchase, ownership and disposition of the notes
and the certificates of any series, to the extent it relates to matters of law
or legal conclusions with respect thereto, represents the opinion of tax counsel
to each trust with respect to the related series on the material matters
associated with such consequences, subject to the qualifications set forth in
this section of this prospectus. "Tax counsel" with respect to each trust will
be Andrews & Kurth L.L.P. The summary does not purport to deal with federal
income tax consequences applicable to all categories of investors, some of which
may be subject to special rules. For example, it does not discuss the tax
treatment of noteholders or certificateholders that are insurance companies,
regulated investment companies or dealers in securities. Moreover, there are no
cases or IRS rulings on similar transactions involving both debt and equity
interests issued by a trust with terms similar to those of the notes and the
certificates. As a result, the IRS may disagree with all or a part of the
discussion below. Prospective investors are urged to consult their own tax
advisors in determining the federal, state, local, foreign and any other tax
consequences to them of the purchase, ownership and disposition of the notes and
the certificates.

         The following summary is based upon current provisions of the tax code
- - the Internal Revenue Code of 1986, as amended, the Treasury regulations
promulgated thereunder and judicial or ruling authority, all of which are
subject to change, which change may be retroactive. Each trust will be provided
with an opinion of tax counsel regarding certain federal income tax matters
discussed below. An opinion of tax counsel, however, is not binding on the IRS
or the courts. No ruling on any of the issues discussed below will be sought
from the IRS. For purposes of the following summary, references to the trust,
the notes, the certificates and related terms, parties and documents shall be
deemed to refer, unless otherwise specified herein, to each trust and the notes,
certificates and related terms, parties and


                                       58

<PAGE>   64

documents applicable to the trust. The federal income tax consequences to
certificateholders will vary depending on whether an election is made to treat
the trust as a partnership under the tax code or whether the trust will be
treated as a grantor trust. The prospectus supplement for each series of
certificates will specify whether a partnership election will be made or the
trust will be treated as a grantor trust.


                 TRUSTS FOR WHICH A PARTNERSHIP ELECTION IS MADE

TAX CHARACTERIZATION OF THE TRUST AS A PARTNERSHIP

         The following general discussion of the anticipated federal income tax
consequences of the purchase, ownership and disposition of the notes and the
certificates of a trust for which a partnership election will be made, to the
extent it relates to matters of law or legal conclusions with respect thereto,
represents the opinion of tax counsel to each trust with respect to the related
series on the material matters associated with such consequences, subject to the
qualifications set forth in this section of this prospectus. In addition, tax
counsel has prepared or reviewed the statements in the prospectus under the
heading "Certain Federal Income Tax Consequences - Trusts for Which a
Partnership Election is Made", and is of the opinion that the statements are
correct in all material respects. Those statements are intended as an
explanatory discussion of the related tax matters affecting investors generally,
but do not purport to furnish information in the level of detail or with the
attention to an investor's specific tax circumstances that would be provided by
an investor's own tax advisor. Accordingly, each investor is advised to consult
its own tax advisors with regard to the tax consequences to it of investing in
notes or certificates.

         Tax counsel will deliver its opinion that a trust for which a
partnership election is made will not be an association, or publicly traded
partnership, taxable as a corporation for federal income tax purposes. This
opinion will be based on the assumption that the terms of the trust agreement
and related documents will be complied with, and on counsel's conclusions that
the nature of the income of the trust will exempt it from the rule that some
publicly traded partnerships are taxable as corporations.

         If the trust were taxable as a corporation for federal income tax
purposes, the trust would be subject to corporate income tax on its taxable
income. The trust's taxable income would include all its income on the
contracts, possibly reduced by its interest expense on the notes. Any corporate
income tax could materially reduce cash available to make payments on the notes
and distributions on the certificates, and certificateholders could be liable
for any corporate income tax that is unpaid by the trust.

TAX CONSEQUENCES TO HOLDERS OF THE NOTES

         TREATMENT OF THE NOTES AS INDEBTEDNESS. The seller will agree, and the
noteholders will agree by their purchase of notes, to treat the notes as debt
for federal income tax purposes. Tax counsel will, except as otherwise provided
in the related prospectus supplement, advise the trust that the notes will be
classified as debt for federal income tax purposes. The discussion below assumes
this characterization of the notes is correct.

                                       59

<PAGE>   65

         OID, INDEXED SECURITIES, ETC. The discussion below assumes that all
payments on the notes are denominated in U.S. dollars, and that the notes are
not strip notes. Moreover, the discussion assumes that the interest formula for
the notes meets the requirements for "qualified stated interest" under Treasury
regulations relating to original issue discount -- or OID -- and that any OID on
the notes (i.e., any excess of the principal amount of the notes over their
issue price) does not exceed a de minimis amount (i.e., 1/4% of their principal
amount multiplied by the number of full years included in their term), all
within the meaning of the OID regulations. If these conditions are not satisfied
with respect to any given series of notes, additional tax considerations with
respect to the notes will be disclosed in the applicable prospectus supplement.

         INTEREST INCOME ON THE NOTES. Based on the above assumptions, except as
discussed in the following paragraph, the notes will not be considered issued
with OID. The stated interest thereon will be taxable to a noteholder as
ordinary interest income when received or accrued in accordance with the
noteholder's method of tax accounting. Under the OID regulations, a holder of a
note issued with a de minimis amount of OID must include the OID in income, on a
pro rata basis, as principal payments are made on the note. A purchaser who buys
a note for more or less than its principal amount will generally be subject,
respectively, to the premium amortization or market discount rules of the tax
code.

         A holder of a short-term note -- one that has a fixed maturity date of
not more than one year from the issue date of the note -- may be subject to
special rules. An accrual basis holder of a short-term note, and specific cash
method holders, including regulated investment companies, as set forth in
Section 1281 of the tax code, generally would be required to report interest
income as interest accrues on a straight-line basis over the term of each
interest period. Other cash basis holders of a short-term note would, in
general, be required to report interest income as interest is paid or, if
earlier, upon the taxable disposition of the short-term note. However, a cash
basis holder of a short-term note reporting interest income as it is paid may be
required to defer a portion of any interest expense otherwise deductible on
indebtedness incurred to purchase or carry the short-term note until the taxable
disposition of the short-term note. A cash basis taxpayer may elect under
Section 1281 of the tax code to accrue interest income on all non-government
debt obligations with a term of one year or less, in which case the taxpayer
would include interest on the short-term note in income as it accrues, but would
not be subject to the interest expense deferral rule referred to in the
preceding sentence. Certain special rules apply if a short-term note is
purchased for more or less than its principal amount.

         SALE OR OTHER DISPOSITION. If a noteholder sells a note, the holder
will recognize gain or loss in an amount equal to the difference between the
amount realized on the sale and the holder's adjusted tax basis in the note. The
adjusted tax basis of a note to a particular noteholder will equal the holder's
cost for the note, increased by any market discount, acquisition discount, OID
and gain previously included by the noteholder in income with respect to the
note and decreased by the amount of bond premium, if any, previously amortized
and by the amount of principal payments previously received by the noteholder
with respect to that note. This gain or loss will be capital gain or loss if the
note was held as a capital asset, except for gain representing accrued interest
and accrued market discount not previously included in income. Capital losses
generally may be used only to offset capital gains.

         FOREIGN HOLDERS. Interest payments made, or accrued, to a noteholder
who is a foreign person -- a nonresident alien, foreign corporation or other
non-United States person -- generally will be considered "portfolio interest,"
and generally will not be subject to United States federal income tax and


                                       60

<PAGE>   66

withholding tax, if the interest is not effectively connected with the conduct
of a trade or business within the United States by the foreign person and the
foreign person:

          -    is not actually or constructively a "10 percent shareholder" of
               the trust or the seller, including a holder of 10% of the
               outstanding certificates, or a "controlled foreign corporation"
               with respect to which the trust or the seller is a "related
               person" within the meaning of the tax code; and

          -    provides the trustee or other person who is otherwise required to
               withhold U.S. tax with respect to the notes with an appropriate
               statement, on Form W-8 or a similar form, signed under penalties
               of perjury, certifying that the beneficial owner of the note is a
               foreign person and providing the foreign person's name and
               address.

         If a note is held through a securities clearing organization or certain
other financial institutions, the organization or institution may provide the
relevant signed statement to the withholding agent; in that case, however, the
signed statement must be accompanied by a Form W-8 or substitute form provided
by the foreign person that owns the note. If the interest is not portfolio
interest, then it will be subject to United States federal income and
withholding tax at a rate of 30 percent, unless reduced or eliminated under an
applicable tax treaty.

         Any capital gain realized on the sale, redemption, retirement or other
taxable disposition of a note by a foreign person will be exempt from United
States federal income and withholding tax, provided that:

          -    the gain is not effectively connected with the conduct of a trade
               or business in the United States by the foreign person; and

          -    in the case of an individual foreign person, the foreign person
               is not present in the United States for 183 days or more in the
               taxable year.

         Final regulations dealing with withholding tax on income paid to
foreign persons and related matters were issued by the Treasury Department on
October 6, 1997. These new withholding regulations will generally be effective
for payments made after December 31, 2000, subject to transition rules.
Prospective investors who are foreign persons are strongly urged to consult
their own tax advisors with respect to the new withholding regulations.

         BACKUP WITHHOLDING. Each holder of a note - other than an exempt holder
such as a corporation, tax-exempt organization, qualified pension and
profit-sharing trust, individual retirement account or nonresident alien who
provides certification as to status as a nonresident - will be required to
provide, under penalties of perjury, a certificate containing the holder's name,
address, correct federal taxpayer identification number and a statement that the
holder is not subject to backup withholding. Should a nonexempt noteholder fail
to provide the required certification, the trust will be required to withhold 31
percent of the amount otherwise payable to the holder, and remit the withheld
amount to the IRS as a credit against the holder's federal income tax liability.


                                       61

<PAGE>   67

         POSSIBLE ALTERNATIVE TREATMENTS OF THE NOTES. If, contrary to the
opinion of tax counsel, the IRS successfully asserted that one or more of the
notes did not represent debt for federal income tax purposes, the notes might be
treated as equity interests in the trust. If so treated, the trust might be
taxable as a corporation with the adverse consequences described above, and the
taxable corporation would not be able to reduce its taxable income by deductions
for interest expense on notes recharacterized as equity. Alternatively, and more
likely in the view of tax counsel, the trust might be treated as a publicly
traded partnership that would not be taxable as a corporation because it would
meet applicable qualifying income tests. Nonetheless, treatment of the notes as
equity interests in such a publicly traded partnership could have adverse tax
consequences to some holders. For example, income to some tax-exempt entities,
including pension funds, would be "unrelated business taxable income," income to
foreign holders generally would be subject to U.S. tax and U.S. tax return
filing and withholding requirements, and individual holders might be subject to
limitations on their ability to deduct their share of trust expenses.

TAX CONSEQUENCES TO HOLDERS OF THE CERTIFICATES

         TREATMENT OF THE TRUST AS A PARTNERSHIP. The seller and the servicer
will agree, and the certificateholders will agree by their purchase of
certificates, to treat the trust as a partnership for purposes of federal and
state income tax, franchise tax and any other tax measured in whole or in part
by income, with the assets of the partnership being the assets held by the
trust, the partners of the partnership being the certificateholders, including
the seller or other entity in its capacity as recipient of distributions with
respect to the residual interest, if any, and the notes being debt of the
partnership. However, the proper characterization of the arrangement involving
the trust, the certificates, the notes, the seller and the servicer is not clear
because there is no authority on transactions closely comparable to that
contemplated by this prospectus.

         A variety of alternative characterizations are possible. For example,
because the certificates have features characteristic of debt, the certificates
might be considered debt of the seller or the trust. Any such characterization
would not result in materially adverse tax consequences to certificateholders as
compared to the consequences from treatment of the certificates as equity in a
partnership, described below. The following discussion assumes that the
certificates represent equity interests in a partnership.

         PARTNERSHIP TAXATION. As a partnership, the trust will not be subject
to federal income tax. Rather, each certificateholder will be required to
separately take into account the holder's allocated share of income, gains,
losses, deductions and credits of the trust. The trust's income will consist
primarily of interest and finance charges earned on the contracts, including
appropriate adjustments for market discount, OID and bond premium, and any gain
upon collection or disposition of contracts. The trust's deductions will consist
primarily of interest accruing with respect to the notes, servicing and other
fees, and losses or deductions upon collection or disposition of contracts.

         The tax items of a partnership are allocable to the partners in
accordance with the tax code, Treasury regulations and the partnership agreement
- - here, the trust agreement and related documents. The trust agreement will
provide, in general, that the certificateholders will be allocated taxable
income of the trust for each month equal to the sum of:


                                       62

<PAGE>   68

          -    the interest that accrues on the certificates in accordance with
               their terms for the month, including interest accruing at the
               interest rate of the certificates for the month and interest on
               amounts previously due on the certificates but not yet
               distributed;

          -    any trust income attributable to discount on the contracts that
               corresponds to any excess of the principal amount of the
               certificates over their initial issue price;

          -    prepayment premium payable to the certificateholders for the
               month; and

          -    any other amounts of income payable to the certificateholders for
               the month.

This allocation will be reduced by any amortization by the trust of premium on
contracts that corresponds to any excess of the issue price of certificates over
their principal amount. All remaining taxable income of the trust will be
allocated to the seller. Based on the economic arrangement of the parties, this
approach for allocating trust income should be permissible under applicable
Treasury regulations, although no assurance can be given that the IRS would not
require a greater amount of income to be allocated to certificateholders.
Moreover, even under the foregoing method of allocation, certificateholders may
be allocated income equal to the entire interest rate of the certificates plus
the other items described above even though the trust might not have sufficient
cash to make current cash distributions of this amount. Thus, cash basis holders
will in effect be required to report income from the certificates on the accrual
basis and certificateholders may become liable for taxes on trust income even if
they have not received cash from the trust to pay these taxes. In addition,
because tax allocations and tax reporting will be done on a uniform basis for
all certificateholders but certificateholders may be purchasing certificates at
different times and at different prices, certificateholders may be required to
report on their tax returns taxable income that is greater or less than the
amount reported to them by the trust.

         All of the taxable income allocated to a certificateholder that is a
pension, profit sharing or employee benefit plan or other tax-exempt entity,
including an individual retirement account, will constitute "unrelated business
taxable income" generally taxable to the certificateholder under the tax code.

         An individual taxpayer's share of expenses of the trust, including fees
to the servicer but not interest expense, would be miscellaneous itemized
deductions and thus allowable as a deduction only to the extent that in the
aggregate all of the expenses exceed two percent of the individual tax payer's
adjusted gross income. Furthermore, some otherwise allowable itemized deductions
will be reduced, but not by more than 80%, by an amount equal to 3% of the
individual's adjusted gross income in excess of a statutorily defined threshold.
Therefore, these deductions might be disallowed to the individual in whole or in
part and might result in the holder being taxed on an amount of income that
exceeds the amount of cash actually distributed to the holder over the life of
the trust.

         The trust intends to make all tax calculations relating to income and
allocations to certificateholders on an aggregate basis. If the IRS were to
require that these calculations be made separately for each contract, the trust
might be required to incur additional expense but it is believed that there
would not be a material adverse effect on certificateholders.

                                       63

<PAGE>   69

         DISCOUNT AND PREMIUM. It is believed that the contracts were not issued
with OID, and, therefore, the trust should not have OID income. However, the
purchase price paid by the trust for the contracts may be greater or less than
the remaining principal balance of the contracts at the time of purchase. If so,
the contracts will have been acquired at a premium or discount, as the case may
be. As indicated above, the trust will make this calculation on an aggregate
basis, but might be required to recompute it on a contract-by-contract basis.

         If the trust acquires the contracts at a market discount or premium,
the trust will elect to include the market discount in income currently as it
accrues over the life of the contracts or to offset any market premium against
interest income on the contracts. As indicated above, a portion of the market
discount income or premium deduction may be allocated to certificateholders.

         SECTION 708 TERMINATION. Under Section 708 of the tax code, the trust
will be deemed to terminate for federal income tax purposes if 50% or more of
the capital and profits interests in the trust are sold or exchanged within a
12-month period. If this type of termination occurs, the trust will be
considered to contribute its assets to a new partnership and, immediately
thereafter, the terminated partnership distributes interests in the new
partnership to the partners in liquidation of the terminated partnership. The
trust will not comply with technical requirements that might apply when a
constructive termination occurs. As a result, the trust may be subject to tax
penalties and may incur additional expenses if it is required to comply with
those requirements. Furthermore, the trust might not be able to comply due to
lack of data.

         DISPOSITION OF CERTIFICATES. Generally, capital gain or loss will be
recognized on a sale of certificates in an amount equal to the difference
between the amount realized and the seller's tax basis in the certificates sold.
A certificateholder's tax basis in a certificate will generally equal the
holder's cost increased by the holder's share of trust income, includible in
income, and decreased by any distributions received with respect to the
certificate. In addition, both the tax basis in the certificates and the amount
realized on a sale of a certificate would include the holder's share of the
notes and other liabilities of the trust. A holder acquiring certificates at
different prices may be required to maintain a single aggregate adjusted tax
basis in the certificates, and, upon sale or other disposition of some of the
certificates, allocate a portion of the aggregate tax basis to the certificates
sold, rather than maintaining a separate tax basis in each certificate for
purposes of computing gain or loss on a sale of that certificate.

         Any gain on the sale of a certificate attributable to the holder's
share of unrecognized accrued market discount on the contracts would generally
be treated as ordinary income to the holder and would give rise to special tax
reporting requirements. The trust does not expect to have any other assets that
would give rise to special tax reporting requirements. Thus, to avoid those
special reporting requirements, the trust will elect to include market discount
in income as it accrues.

         If a certificateholder is required to recognize an aggregate amount of
income, not including income attributable to disallowed itemized deductions
described above, over the life of the certificates that exceeds the aggregate
cash distributions with respect thereto, the excess will generally give rise to
a capital loss upon the retirement of the certificates.

         ALLOCATIONS BETWEEN TRANSFERORS AND TRANSFEREES. In general, the
trust's taxable income and losses will be determined monthly and the tax items
for a particular calendar month will be apportioned

                                       64

<PAGE>   70

among the certificateholders in proportion to the principal amount of
certificates owned by them as of the close of the last day of the month. As a
result, a holder purchasing certificates may be allocated tax items, which will
affect its tax liability and tax basis, attributable to periods before the
actual transaction.

         The use of this type of monthly convention may not be permitted by
existing regulations. If a monthly convention is not allowed, or only applies to
transfers of less than all of the partner's interest, taxable income or losses
of the trust might be reallocated among the certificateholders. The seller is
authorized to revise the trust's method of allocation between transferors and
transferees to conform to a method permitted by future regulations.

         Section 754 Election. In the event that a certificateholder sells its
certificates at a profit or loss, the purchasing certificateholder will have a
higher or lower basis, respectively, in the certificates than the selling
certificateholder had. The tax basis of the trust's assets will not be adjusted
to reflect that higher or lower basis unless the trust were to file an election
under Section 754 of the tax code. In order to avoid the administrative
complexities that would be involved in keeping accurate accounting records, as
well as potentially onerous information reporting requirements, the trust will
not make an election under Section 754. As a result, certificateholders might be
allocated a greater or lesser amount of trust income than would be appropriate
based on their own purchase price for certificates.

         Administrative Matters. The trustee is required to keep or have kept
complete and accurate books of the trust. The books will be maintained for
financial reporting and tax purposes on an accrual basis and the fiscal year of
the trust will be set forth in the related prospectus supplement. The trustee
will file a partnership information return on IRS Form 1065 with the IRS for
each taxable year of the trust and will report each certificateholder's
allocable share of items of trust income and expense to holders and the IRS on
Schedule K-1. The trust will provide the Schedule K-1 information to nominees
that fail to provide the trust with the information statement described below
and the nominees will be required to forward such information to the beneficial
owners of the certificates. Generally, holders must file tax returns that are
consistent with the information return filed by the trust or be subject to
penalties unless the holder notifies the IRS of all inconsistencies.

         Under Section 6031 of the tax code, any person that holds certificates
as a nominee at any time during a calendar year is required to furnish the trust
with a statement containing information on the nominee, the beneficial owners
and the certificates so held. This information includes

          -    the name, address and taxpayer identification number of the
               nominee; and

          -    as to each beneficial owner:

               -    the beneficial owner's name, address and identification
                    number;

               -    whether the beneficial owner is a United States person, a
                    tax-exempt entity or a foreign government, an international
                    organization, or any wholly owned agency or instrumentality
                    of either of the foregoing; and

               -    information on certificates that were held, bought or sold
                    on behalf of the beneficial owner throughout the year.

In addition, brokers and financial institutions that hold certificates through a
nominee are required to furnish directly to the trust information as to
themselves and their ownership of certificates. A clearing agency registered
under Section 17A of the Securities Exchange Act of 1934, as amended, is not
required to furnish an information statement to the trust. The information
referred to above for any calendar year must be furnished to the trust on or
before the following January 31. Nominees, brokers and financial institutions
that fail to provide the trust with the information described above may be
subject to penalties.

         The seller will be designated as the tax matters partner in the related
trust agreement and, as such, will be responsible for representing the
certificateholders in any dispute with the IRS. The tax code provides for
administrative examination of a partnership as if the partnership were a
separate and distinct taxpayer. Generally, the statute of limitations for
partnership items does not expire before three years after the date on which the
partnership information return is filed. Any adverse determination following an
audit of the return of the trust by the appropriate taxing authorities could
result in an adjustment of the returns of the certificateholders, and, under
some circumstances, a certificateholder may be precluded from separately
litigating a proposed adjustment to the items of the trust. An adjustment could
also result in an audit of a certificateholder's returns and adjustments of
items not related to the income and losses of the trust.

         TAX CONSEQUENCES TO FOREIGN CERTIFICATEHOLDERS. It is not clear whether
the trust would be considered to be engaged in a trade or business in the United
States for purposes of federal withholding taxes with respect to non-U.S.
persons because there is no clear authority dealing with that issue under facts
substantially similar to those described in this prospectus. Although it is not
expected that the trust would be engaged in a trade or business in the United
States for these purposes, the trust will withhold as if it were so engaged in
order to protect the trust from possible adverse consequences of a failure to
withhold. The trust expects to withhold on the portion of its taxable income
that is allocable to foreign certificateholders under Section 1446 of the tax
code, as if the income were effectively connected to a U.S. trade or business,
at a rate of 35% for foreign holders that are taxable as corporations and 39.6%
for all other foreign holders. The new withholding regulations or subsequent
adoption of Treasury regulations or the issuance of other administrative
pronouncements may require the trust to change its withholding procedures. In
determining a holder's withholding status, the trust may rely on IRS Form W-8,
IRS Form W-9 or the holder's certification of nonforeign status signed under
penalties of perjury.

         Each foreign holder might be required to file a U.S. individual or
corporate income tax return, including, in the case of a corporation, the branch
profits tax, on its share of the trust's income. Each foreign holder must obtain
a taxpayer identification number from the IRS and submit that number to the
trust on Form W-8 in order to assure appropriate crediting of the taxes
withheld. A foreign holder generally would be entitled to file with the IRS a
claim for refund with respect to taxes withheld by the trust, taking the
position that no taxes were due because the trust was not engaged in a U.S.
trade or business. However, interest payments made, or accrued, to a
certificateholder who is a foreign person generally will be considered
guaranteed payments to the extent the payments are determined without regard to
the income of the trust. If these interest payments are properly characterized
as guaranteed payments, then the interest will not be considered "portfolio
interest." As a result, certificateholders will be subject to United States
federal income tax and withholding tax at a rate of 30 percent, unless reduced
or eliminated under an applicable treaty. In this case, a foreign holder would
only be entitled to claim a

                                       66

<PAGE>   72

refund for that portion of the taxes in excess of the taxes that should be
withheld with respect to the guaranteed payments.

         BACKUP WITHHOLDING. Distributions made on the certificates and proceeds
from the sale of the certificates will be subject to a "backup" withholding tax
of 31% if, in general, the certificateholder fails to comply with applicable
identification procedures, unless the holder is an exempt recipient under
applicable provisions of the tax code.


                        TRUSTS TREATED AS GRANTOR TRUSTS

TAX CHARACTERIZATION OF THE TRUST AS A GRANTOR TRUST

         The following general discussion of the anticipated federal income tax
consequences of the purchase, ownership and disposition of the certificates of a
trust for which a partnership election will not be made, to the extent it
relates to matters of law or legal conclusions with respect thereto, represents
the opinion of tax counsel to each trust with respect to the related series on
the material matters associated with these consequences, subject to the
qualifications set forth in this section of this prospectus. In addition, tax
counsel has prepared or reviewed the statements in the prospectus under the
heading "Certain Federal Income Tax Consequences - Trusts Treated as Grantor
Trusts", and is of the opinion that the statements are correct in all material
respects. The statements are intended as an explanatory discussion of the
possible effects of the classification of any trust as a grantor trust for
federal income tax purposes on investors generally and of related tax matters
affecting investors generally, but do not purport to furnish information in the
level of detail or with the attention to an investor's specific tax
circumstances that would be provided by an investor's own tax advisor.
Accordingly, each investor is advised to consult its own tax advisors with
regard to the tax consequences to it of investing in certificates.

         If a partnership election is not made, tax counsel will deliver its
opinion that the trust will not be classified as an association taxable as a
corporation and that the trust will be classified as a grantor trust under
subpart E, Part I of subchapter J of Chapter 1 of Subtitle A of the tax code. In
this case, owners of certificates issued by a trust that is treated as a grantor
trust - grantor trust certificates - will be treated for federal income tax
purposes as owners of a portion of the trust's assets as described below.

         CHARACTERIZATION. Each grantor trust certificateholder will be treated
as the owner of a pro rata undivided interest in the interest and principal
portions of the trust represented by the grantor trust certificates and will be
considered the equitable owner of a pro rata undivided interest in each of the
contracts in the trust. Any amounts received by a grantor trust
certificateholder in lieu of amounts due with respect to any contract because of
a default or delinquency in payment will be treated for federal income tax
purposes as having the same character as the payments they replace.

         Each grantor trust certificateholder will be required to report on its
federal income tax return in accordance with the grantor trust
certificateholder's method of accounting its pro rata share of the entire income
from the contracts in the trust represented by grantor trust certificates,
including interest, OID, if any, prepayment fees, assumption fees, any gain
recognized upon an assumption and late payment charges received by the servicer.
Under Sections 162 or 212, each grantor trust certificateholder will be

                                       67

<PAGE>   73

entitled to deduct its pro rata share of servicing fees, prepayment fees,
assumption fees, any loss recognized upon an assumption and late payment charges
retained by the servicer, provided that the amounts are reasonable compensation
for services rendered to the trust. Grantor trust certificateholders that are
individuals, estates or trusts will be entitled to deduct their share of
expenses only to the extent these expenses plus all other Section 212 expenses
exceed two percent of its adjusted gross income. A grantor trust
certificateholder using the cash method of accounting must take into account its
pro rata share of income and deductions as and when collected by or paid to the
servicer. A grantor trust certificateholder using an accrual method of
accounting must take into account its pro rata share of income and deductions as
they become due or are paid to the servicer, whichever is earlier. If the
servicing fees paid to the servicer are deemed to exceed reasonable servicing
compensation, the amount of this excess could be considered as an ownership
interest retained by the servicer, or any person to whom the servicer assigned
for value all or a portion of the servicing fees, in a portion of the interest
payments on the contracts. The contracts would then be subject to the "coupon
stripping" rules of the tax code discussed below.

         PREMIUM. The price paid for a grantor trust certificate by a holder
will be allocated to the holder's undivided interest in each contract based on
each contract's relative fair market value, so that the holder's undivided
interest in each contract will have its own tax basis. A grantor trust
certificateholder that acquires an interest in contracts at a premium may elect
to amortize the premium under a constant interest method. Amortizable bond
premium will be treated as an offset to interest income on the grantor trust
certificate. The basis for the grantor trust certificate will be reduced to the
extent that amortizable premium is applied to offset interest payments. It is
not clear whether a reasonable prepayment assumption should be used in computing
amortization of premium allowable under Section 171. A grantor trust
certificateholder that makes this election for a grantor trust certificate that
is acquired at a premium will be deemed to have made an election to amortize
bond premium with respect to all debt instruments having amortizable bond
premium that the grantor trust certificateholder acquires during the year of the
election or thereafter.

         If a premium is not subject to amortization using a reasonable
prepayment assumption, the holder of a grantor trust certificate acquired at a
premium should recognize a loss if a contract prepays in full, equal to the
difference between the portion of the prepaid principal amount of the contract
that is allocable to the grantor trust certificate and the portion of the
adjusted basis of the grantor trust certificate that is allocable to the
contract. If a reasonable prepayment assumption is used to amortize the premium,
it appears that such a loss would be available, if at all, only if prepayments
have occurred at a rate faster than the reasonable assumed prepayment rate. It
is not clear whether any other adjustments would be required to reflect
differences between an assumed prepayment rate and the actual rate of
prepayments.

STRIPPED BONDS AND STRIPPED COUPONS

         Although the tax treatment of stripped bonds is not entirely clear,
based on guidance issued by the IRS, each purchaser of a grantor trust
certificate will be treated as the purchaser of a stripped bond which generally
should be treated as a single debt instrument issued on the day it is purchased
for purposes of calculating any OID. Generally, under applicable Treasury
regulations promulgated under Section 1286 of the tax code, if the discount on a
stripped bond is larger than a de minimis amount, as calculated for purposes of
the OID rules of the tax code, the stripped bond will be considered to have


                                       68

<PAGE>   74

been issued with OID. See "- Original Issue Discount" below. Based on the
preamble to the Section 1286 Treasury regulations, tax counsel is of the opinion
that, although the matter is not entirely clear, the interest income on the
certificates at the sum of the interest rate of the certificates and the portion
of the servicing fee rate that does not constitute excess servicing will be
treated as "qualified stated interest" within the meaning of the Section 1286
Treasury regulations and this income will be so treated in the trustee's tax
information reporting.

         ORIGINAL ISSUE DISCOUNT. The IRS has stated in published rulings that,
in circumstances similar to those described in this prospectus, the special
rules of the tax code relating to OID - currently Sections 1271 through 1273 and
1275 - will be applicable to a grantor trust certificateholder's interest in
those contracts meeting the conditions necessary for these sections to apply.
Generally, a grantor trust certificateholder that acquires an undivided interest
in a contract issued or acquired with OID must include in gross income the sum
of the "daily portions," as defined below, of the OID on the contract for each
day on which it owns a certificate, including the date of purchase but excluding
the date of disposition. In the case of an original grantor trust
certificateholder, the daily portions of OID with respect to a contract
generally would be determined as follows. A calculation will be made of the
portion of OID that accrues on the contract during each successive monthly
accrual period, or shorter period in respect of the date of original issue or
the final distribution date. This will be done, in the case of each full monthly
accrual period, by adding:

          -    the present value of all remaining payments to be received on the
               contract under the prepayment assumption used in respect of the
               contracts; and

          -    any payments received during the accrual period, and subtracting
               from that total the "adjusted issue price" of the contract at the
               beginning of the accrual period.

No representation is made that the contracts will prepay at any prepayment
assumption. The "adjusted issue price" of a contract at the beginning of the
first accrual period is its issue price, as determined for purposes of the OID
rules of the tax code, and the "adjusted issue price" of a contract at the
beginning of a subsequent accrual period is the "adjusted issue price" at the
beginning of the immediately preceding accrual period plus the amount of OID
allocable to that accrual period and reduced by the amount of any payment, other
than "qualified stated interest," made at the end of or during that accrual
period. The OID accruing during that accrual period will then be divided by the
number of days in the period to determine the daily portion of OID for each day
in the period. With respect to an initial accrual period shorter than a full
monthly accrual period, the daily portions of OID must be determined according
to a reasonable method, provided that the method is consistent with the method
used to determine the yield to maturity of the contracts.

         With respect to the contracts, the method of calculating OID as
described above will cause the accrual of OID to either increase or decrease,
but never below zero, in any given accrual period to reflect the fact that
prepayments are occurring at a faster or slower rate than the prepayment
assumption used in respect of the contracts. Subsequent purchasers that purchase
contracts at more than a de minimis discount should consult their tax advisors
with respect to the proper method to accrue this OID.

         The Taxpayer Relief Act of 1997 requires the use of a prepayment
assumption to accrue OID with respect to "any pool of debt instruments the yield
on which may be affected by reason of

                                       69

<PAGE>   75

prepayments (or to the extent provided in regulation, by reason of other
events)." Unless otherwise provided in the related prospectus supplement, the
trustee will deem the prepayment assumption to be that the contracts will not
prepay. If the IRS were to require that OID be computed using a different
prepayment assumption, the character and timing of a certificateholder's income
could be adversely affected.

         MARKET DISCOUNT. A grantor trust certificateholder that acquires an
undivided interest in contracts may be subject to the market discount rules of
Sections 1276 through 1278 to the extent an undivided interest in a contract is
considered to have been purchased at a "market discount." Generally, the amount
of market discount is equal to the excess of the portion of the principal amount
of the contract allocable to the holder's undivided interest over the holder's
tax basis in such interest. Market discount with respect to a grantor trust
certificate will be considered to be zero if the amount allocable to the grantor
trust certificate is less than 0.25% of the grantor trust certificate's stated
redemption price at maturity multiplied by the weighted average maturity
remaining after the date of purchase. Treasury regulations implementing the
market discount rules have not yet been issued; therefore, investors should
consult their own tax advisors regarding the application of these rules and the
advisability of making any of the elections allowed under Sections 1276 through
1278 of the tax code.

         The tax code provides that any principal payment, whether a scheduled
payment or a prepayment, or any gain on disposition of a market discount bond
shall be treated as ordinary income to the extent that it does not exceed the
accrued market discount at the time of this payment. The amount of accrued
market discount for purposes of determining the tax treatment of subsequent
principal payments or dispositions of the market discount bond is to be reduced
by the amount so treated as ordinary income.

         The tax code also grants the Treasury Department authority to issue
regulations providing for the computation of accrued market discount on debt
instruments, the principal of which is payable in more than one installment.
While the Treasury Department has not yet issued regulations, rules described in
the relevant legislative history will apply. Under those rules, the holder of a
market discount bond may elect to accrue market discount either on the basis of
a constant interest rate or according to one of the following methods. If a
grantor trust certificate is issued with OID, the amount of market discount that
accrues during any accrual period would be equal to the product of:

          -    the total remaining market discount; and

          -    a fraction, the numerator of which is the OID accruing during the
               period and the denominator of which is the total remaining OID at
               the beginning of the accrual period.

For grantor trust certificates issued without OID, the amount of market discount
that accrues during a period is equal to the product of:

          -    the total remaining market discount; and

          -    a fraction, the numerator of which is the amount of stated
               interest paid during the accrual period and the denominator of
               which is the total amount of stated interest remaining to be paid
               at the beginning of the accrual period.


                                       70

<PAGE>   76

For purposes of calculating market discount under any of the above methods in
the case of instruments, such as the grantor trust certificates, that provide
for payments that may be accelerated by reason of prepayments of other
obligations securing these instruments, the same prepayment assumption
applicable to calculating the accrual of OID will apply. Because the regulations
described above have not been issued, it is impossible to predict what effect
those regulations might have on the tax treatment of a grantor trust certificate
purchased at a discount or premium in the secondary market.

         A holder who acquired a grantor trust certificate at a market discount
also may be required to defer a portion of its interest deductions for the
taxable year attributable to any indebtedness incurred or continued to purchase
or carry the grantor trust certificate purchased with market discount. For these
purposes, the de minimis rule referred above applies. Any deferred interest
expense would not exceed the market discount that accrues during the taxable
year and is, in general, allowed as a deduction not later than the year in which
the market discount is includible in income. If the holder elects to include
market discount in income currently as it accrues on all market discount
instruments acquired by the holder in that taxable year or thereafter, the
interest deferral rule described above will not apply.

         PREMIUM. To the extent a grantor trust certificateholder is considered
to have purchased an undivided interest in a contract for an amount that is
greater than its stated redemption price at maturity of the contract, the
grantor trust certificateholder will be considered to have purchased the
contract with "amortizable bond premium" equal in amount to the excess. A
grantor trust certificateholder who does not hold the certificate for sale to
customers or in inventory may elect under Section 171 of the tax code to
amortize the premium. Under the tax code, premium is allocated among the
interest payments on the contracts to which it relates and is considered as an
offset against, and thus a reduction of, the interest payments. With certain
exceptions, such an election would apply to all debt instruments held or
subsequently acquired by the electing holder. Absent this type of election, the
premium will be deductible as an ordinary loss only upon disposition of the
certificate or pro rata as principal is paid on the contracts.

         ELECTION TO TREAT ALL INTEREST AS OID. The OID regulations permit a
grantor trust certificateholder to elect to accrue all interest, discount,
including de minimis market or OID, and premium in income as interest, based on
a constant yield method. If this election were to be made with respect to a
grantor trust certificate with market discount, the certificateholder would be
deemed to have made an election to include in income currently market discount
with respect to all other debt instruments having market discount that the
grantor trust certificateholder acquires during the year of the election or
thereafter. Similarly, a grantor trust certificateholder that makes this
election for a grantor trust certificate that is acquired at a premium will be
deemed to have made an election to amortize bond premium with respect to all
debt instruments having amortizable bond premium that the grantor trust
certificateholder owns or acquires. See "- Premium" above. The election to
accrue interest, discount and premium on a constant yield method with respect to
a grantor trust certificate is irrevocable.

         SALE OR EXCHANGE OF A GRANTOR TRUST CERTIFICATE. Sale or exchange of a
grantor trust certificate prior to its maturity will result in gain or loss
equal to the difference, if any, between the amount received and the owner's
adjusted basis in the grantor trust certificate. The adjusted basis generally
will equal the seller's purchase price for the grantor trust certificate,
increased by the OID included in the seller's gross income with respect to the
grantor trust certificate, and reduced by principal payments on


                                       71

<PAGE>   77

the grantor trust certificate previously received by the seller. The gain or
loss will be capital gain or loss to an owner for which a grantor trust
certificate is a "capital asset" within the meaning of Section 1221, and will be
long-term or short-term depending on whether the grantor trust certificate has
been owned for the long-term capital gain holding period, currently more than
one year.

         Grantor trust certificates will be "evidences of indebtedness" within
the meaning of Section 582(c)(1), so that gain or loss recognized from the sale
of a grantor trust certificate by a bank or a thrift institution to which this
section applies will be treated as ordinary income or loss.

         NON-U.S. PERSONS. Generally, interest or OID paid by the person
required to withhold tax under Section 1441 or 1442 to (i) an owner that is not
a "U.S. person," as defined below, or (ii) a grantor trust certificateholder
holding on behalf of an owner that is not a U.S. person and accrued OID
recognized by the owner on the sale or exchange of such a grantor trust
certificate will not be subject to withholding to the extent that a grantor
trust certificate evidences ownership in contracts issued after July 18, 1984 by
natural persons if the grantor trust certificateholder complies with applicable
identification requirements, including delivery of a statement, signed by the
grantor trust certificateholder under penalties of perjury, certifying that the
grantor trust certificateholder is not a U.S. person and providing the name and
address of the grantor trust certificateholder. Additional restrictions apply to
contracts where the obligor is not a natural person in order to qualify for the
exemption from withholding.

         As used in this prospectus, a "U.S. 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, except, in the case of a partnership, as
               otherwise provided by regulations;

          -    an estate, the income of which is includible in gross income for
               United States federal income tax purposes regardless of its
               source; or

          -    a trust whose administration is subject to the primary
               supervision of a United States court and which has one or more
               United States persons who have authority to control all
               substantial decisions of the trust.

         INFORMATION REPORTING AND BACKUP WITHHOLDING. The servicer will furnish
or make available, within a reasonable time after the end of each calendar year,
to each person who was a grantor trust certificateholder at any time during the
year, such information as may be deemed necessary or desirable to assist grantor
trust certificateholders in preparing their federal income tax returns, or to
enable holders to make the information available to beneficial owners or
financial intermediaries that hold grantor trust certificates as nominees on
behalf of beneficial owners. If a holder, beneficial owner, financial
intermediary or other recipient of a payment on behalf of a beneficial owner
fails to supply a certified taxpayer identification number or if the Secretary
of the Treasury determines that the person has not reported all interest and
dividend income required to be shown on its federal income tax return, 31%
backup withholding may be required with respect to any payments. Any amounts
deducted and withheld

                                       72

<PAGE>   78

from a distribution to a recipient would be allowed as a credit against the
recipient's federal income tax liability.

         THE FEDERAL TAX DISCUSSIONS SET FORTH ABOVE ARE INCLUDED FOR GENERAL
INFORMATION ONLY AND MAY NOT BE APPLICABLE DEPENDING UPON A NOTEHOLDER'S OR
CERTIFICATEHOLDER'S PARTICULAR TAX SITUATION. PROSPECTIVE PURCHASERS SHOULD
CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE TAX CONSEQUENCES TO THEM OF THE
PURCHASE, OWNERSHIP AND DISPOSITION OF NOTES AND CERTIFICATES, INCLUDING THE TAX
CONSEQUENCES UNDER STATE, LOCAL, FOREIGN AND OTHER TAX LAWS AND THE POSSIBLE
EFFECTS OF CHANGES IN FEDERAL OR OTHER TAX LAWS.


                              ERISA CONSIDERATIONS

         ERISA and the tax code prohibit a pension, profit-sharing or other
employee benefit plan, as well as individual retirement accounts and some types
of Keogh Plans - each a "benefit plan" - from engaging in certain transactions
involving "plan assets" with persons that are "parties in interest" under ERISA
or "disqualified persons" under the tax code with respect to the benefit plan.
ERISA also imposes duties on persons who are fiduciaries of benefit plans
subject to ERISA and prohibits certain transactions between a benefit plan and
parties in interest with respect to the benefit plans. Under ERISA, any person
who exercises any authority or control with respect to the management or
disposition of the assets of a benefit plan is considered to be a fiduciary of
the benefit plan, subject to certain exceptions not here relevant. A violation
of these "prohibited transaction" rules may result in an excise tax or other
penalties and liabilities under ERISA and the tax code for such persons.

         Certain transactions involving a trust might be deemed to constitute
prohibited transactions under ERISA and the tax code with respect to a benefit
plan that purchased notes or certificates if assets of the trust were deemed to
be assets of the benefit plan. Under a regulation issued by the United States
Department of Labor, the assets of a trust would be treated as plan assets of a
benefit plan for the purposes of ERISA and the tax code if the benefit plan
acquired an "equity interest" in the trust and none of the exceptions contained
in the regulation was applicable. An equity interest is defined under the
regulation as an interest other than an instrument which is treated as
indebtedness under applicable local law and which has no substantial equity
features. The likely treatment in this context of notes and certificates of a
given series will be discussed in the related prospectus supplement.

         Employee benefit plans that are governmental plans, as defined in
Section 3(32) of ERISA, and certain church plans, as defined in Section 3(33) of
ERISA, are not subject to ERISA requirements. Due to the complexities of the
"prohibited transaction" rules and the penalties imposed upon persons involved
in prohibited transactions, it is important that the fiduciary of any benefit
plan considering the purchase of securities consult with its tax and/or legal
advisors regarding whether the assets of the related trust would be considered
plan assets, the possibility of exemptive relief from the prohibited transaction
rules and other issues and their potential consequences.

                              PLAN OF DISTRIBUTION

         Unless otherwise specified in the related prospectus supplement, on the
terms and conditions set forth in one or more underwriting agreements with
respect to the securities of a series, the seller will agree to cause the
related trust to sell to the underwriter or underwriters named in the
underwriting agreement and in the related prospectus supplement, and each of the
underwriters will severally agree to purchase, the principal amount of each
class of securities, as the case may be, of the related series set forth in the
underwriting agreement and in the related prospectus supplement.

         The related prospectus supplement may provide that the underwriters are
not obligated to purchase all of the securities, but if it does not, then the
applicable underwriter or underwriters will agree in the underwriting agreement
with respect to any given series of securities, subject to the terms and
conditions set forth in the underwriting agreement, to purchase all the
securities described in the agreement which are offered by this prospectus and
the related prospectus supplement if any of the securities are purchased.

         Each prospectus supplement will either (i) set forth the price at which
each class of securities being offered thereby will be offered to the public and
any concessions that may be offered to certain dealers participating in the
offering of the securities or (ii) specify that the related securities are to be
resold by the underwriter(s) in negotiated transactions at varying prices to be
determined at the time of the sale. After the initial public offering of any
securities, the public offering prices and concessions may be changed.

         The related prospectus supplement may specify other indemnification
provisions, but if it does not, each underwriting agreement will provide that

descriptions of the initial contracts set forth above, the characteristics of
the contracts as a whole will not vary materially from the characteristics of
the initial contracts. See "The Contracts" in this prospectus supplement and in
the prospectus.

DISTRIBUTION DATES

Interest and principal on the securities will be payable on the 15th day of each
month. If the 15th day of a month is not a business day, then the payment for
that month will be made on the next succeeding business day. The first payment
will be due on __________, 2000.

A business day is a day other than a Saturday, Sunday or other day on which
commercial banks located in California or New York are authorized or required to
be closed.

TERMS OF THE NOTES

INTEREST RATES:

The trust will pay interest on each class of notes at the rates specified on the
cover of this prospectus supplement.


                                       S-6

<PAGE>   87
Interest on the notes will accrue monthly, as described under "Description of
the Notes Payments of Interest" in this prospectus supplement. Interest on the
notes will be calculated on the basis of a 360-day year of twelve 30-day months,
with the exception of the Class A-1 Notes, with respect to which interest will
be calculated on the basis of a 360-day year and the actual number of days in
the related accrual period.

PRINCIPAL:

The trust will make payments of principal on the notes monthly, on each
distribution date, as described under "Description of the Notes -- Payments of
Principal" and "Description of the Transfer and Servicing Agreements --
Distributions" in this prospectus supplement. No principal payments will be made
on the Class A-2 Notes until the Class A-1 Notes have been paid in full; no
principal payments will be made on the Class A-3 Notes until the Class A-2 Notes
have been paid in full; and no principal payments will be made on the Class A-4
Notes until the Class A-3 Notes have been paid in full.

The trust must pay the outstanding principal amount of each class of notes, to
the extent not previously paid, by the final scheduled distribution date for
that class of notes, which occurs in the following months:

Class A-1 Notes - ________, 200__
Class A-2 Notes - ________, 200__
Class A-3 Notes - ________, 200__
Class A-4 Notes - ________, 200__

We expect that the outstanding principal balance of each class of notes will be
paid in full earlier, and could be paid significantly earlier, than the final
scheduled distribution date for that class, depending on a variety of factors.

MANDATORY PARTIAL REDEMPTION

We will partially redeem the Class A-1 Notes on the first distribution date to
the extent, if any, that the proceeds from the sale of the securities exceeds
the aggregate principal balance of all of the contracts as of their applicable
cut-off date.

TERMS OF THE CERTIFICATES

INTEREST RATE:

The trust will pay interest on the certificates at the rate specified on the
cover of this prospectus supplement.

Interest on the certificates will accrue monthly, as described under
"Description of the Certificates -- Distributions of Interest" in this
prospectus supplement. Distributions of interest on the certificates will be
subordinated to payments of interest on the notes on each distribution date. On
the final scheduled distribution date for a class of notes, interest on the
certificates will be subordinated to payments of principal then due on that
class of Notes. See "Description of the Certificates" in this prospectus
supplement.

PRINCIPAL:

We will not pay principal on the certificates until all of the notes have been
paid in full. On the distribution date that the notes are paid in full, and on
each succeeding distribution date, the trust will make payments of principal on
the certificates monthly, as described under "Description of


                                       S-7

<PAGE>   88
the Certificates - Distributions of Principal" and "Description of the Transfer
and Servicing Agreements - Distributions" in this prospectus supplement.

The trust must pay the outstanding principal amount of the certificates, to the
extent not previously paid, by the final scheduled distribution date for the
certificates, occurring in ______________. We expect that the outstanding
principal balance of the certificates will be paid in full earlier, and could be
paid significantly earlier, than the final scheduled distribution date for the
certificates, depending on a variety of factors.

OPTIONAL PURCHASE

The servicer may, but is not obligated to, purchase the contracts on any
distribution date on which the principal balance of the contracts has declined
to 10% or less of the aggregate principal balance of the contracts as of their
applicable cut-off dates. If the servicer exercises this purchase option, all of
the notes then outstanding will be redeemed, and all of the certificates then
outstanding will be prepaid. See "Description of the Notes -- Optional
Redemption", "Description of the Certificates -- Optional Prepayment" and
"Description of the Transfer and Servicing Agreements -- Termination" in this
prospectus supplement.

THE SPREAD ACCOUNT

The indenture trustee will establish a segregated trust account, entitled
"Spread Account - OT 2000-__, [________________], Indenture Trustee", for the
benefit of the securityholders and [insurer]. The spread account will be an
asset of the trust. The securityholders will be afforded limited protection
against losses on the contracts by the establishment of the spread account.

On each distribution date, the indenture trustee will deposit funds in the
spread account up to a specified maximum amount, as described under "Description
of the Transfer and Servicing Agreements Distributions" in this prospectus
supplement. On each distribution date, funds will be withdrawn from the spread
account to cover any shortfalls in amounts available to pay:

     -    the servicing fee and applicable fees of the indenture trustee, the
          owner trustee and the trust agent; and

     -    interest and principal on the securities.

See "Description of the Transfer and Servicing Agreements - Payment Priorities
of the Notes and the Certificates; The Spread Account" in this prospectus
supplement.

THE INSURANCE POLICY

On the closing date, [insurer] will issue a insurance policy, under the terms of
an insurance agreement, in favor of the indenture trustee, for the benefit of
the securityholders. The policy is a "security insurance policy" as referred to
in the prospectus.

Under the policy, [insurer] will irrevocably and unconditionally guarantee
timely payment of interest and ultimate payment of principal due on then Notes
and the certificates, as described under "The Policy"


                                       S-8

<PAGE>   89
in this prospectus supplement. [Insurer]'s obligations under the policy will be
discharged to the extent that amounts due under the policy are received by the
indenture trustee, whether or not the amounts are properly applied by the
indenture trustee.

For a description of [insurer], see "Description of the Insurer" in this
prospectus supplement.

SERVICING FEE

The servicer will be responsible for managing, administering, servicing, and
collecting on the contracts. As compensation for its services, the servicer will
receive a servicing fee and other amounts, as described in this prospectus
supplement under "Description of the Transfer and Servicing Agreements -
Servicing Fee".

FEDERAL INCOME TAX STATUS

In the opinion of Andrews & Kurth L.L.P., for federal income tax purposes, the
notes will be characterized as debt, and the trust will not be characterized as
an association or a publicly traded partnership taxable as a corporation. See
"Certain Federal Income Tax Consequences" in the prospectus for additional
information concerning the application of federal income tax laws to the trust
and the securities.

ERISA CONSIDERATIONS

Subject to the considerations discussed under "ERISA Considerations" in this
prospectus supplement and in the prospectus, the notes are eligible for purchase
by employee benefit plans that are subject to ERISA. However, neither an
employee benefit plan subject to ERISA or Section 4975 of the tax code nor an
individual retirement account is eligible to purchase the certificates. See
"ERISA Considerations" in this prospectus supplement and in the prospectus.

LEGAL INVESTMENT

The Class A-1 Notes will be eligible securities for purchase by money market
funds under Rule 2a-7 under the Investment Company Act of 1940, as amended.

RATING

At the closing date, Standard & Poor's Ratings Services, a division of The
McGraw-Hill Companies, Inc., and Moody's Investors Service, Inc. will rate the
notes and the certificates in the highest rating category available for the
securities. The ratings of the notes and the certificates will be based
substantially on the issuance of the policy by [insurer]. See "Risk Factors -

Initially, the securities will be in the form of one or more certificates
registered in the name of Cede & Co., as the nominee of The Depository Trust
Company. If you acquire an interest in the notes or the certificates through
DTC, you will not be entitled to receive a definitive security, except in the
event that definitive securities are issued in limited circumstances. See
"Description of the Securities - Book-Entry Registration" and "- Definitive
Securities" in the Prospectus.

                                  RISK FACTORS

         You should consider the following risk factors, as well as the other
factors described under the heading "Risk Factors" in the prospectus, before
deciding to purchase the securities.

ONYX IS SUBJECT TO ALL OF THE RISKS INHERENT IN A RELATIVELY NEW BUSINESS
ENTERPRISE BECAUSE OF ITS LIMITED OPERATING HISTORY.

         Onyx began its operations in February 1994 as a purchaser and servicer
of motor vehicle retail installment sales contracts. Accordingly, Onyx has
performance data for only a relatively short period with respect to the
contracts it purchases and originates. As the portfolio of contracts purchased
and originated by Onyx and its subsidiaries matures, delinquency percentages and
loan losses may increase.

         As Onyx expands its operations in the United States, it 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.

         Onyx experienced operating losses from its inception through December
31, 1995. Onyx's operating losses and net income for the years ended December
31, 1994 through December 31, 1998, and for the ___ months ended ________, are
set forth below:

THE ABSENCE OF A SECONDARY MARKET COULD LIMIT YOUR ABILITY TO RESELL YOUR
SECURITIES.

         The absence of a secondary market for the notes and certificates could
limit your ability to resell them. This means that if in the future you want to
sell any of your notes or certificates before they mature, you may be unable to
find a buyer or, if you find a buyer, the selling price may be less than it
would have been if a market existed for the securities. There is currently no
secondary market for the securities. The underwriters currently intend to
participate in making a secondary market in the securities, but they are not
under any obligation to do so. We cannot assure you that a secondary market for
the securities will develop. If a secondary market does develop, we cannot
assure you that it will continue or that you will be able to resell your
securities.

PREPAYMENTS ON CONTRACTS WILL CAUSE PREPAYMENTS ON YOUR SECURITIES RESULTING IN
REINVESTMENT RISK TO YOU.

         You may receive payment of principal on your securities earlier than
you expect for the reasons set forth below. You may not be able to reinvest any
principal paid to you earlier than you expected at a rate of return that is
equal to or greater than the rate of return on your securities.

         Prepayments on the contracts by the related obligors and purchases of
the contracts by the seller and the servicer will shorten the life of the
securities to an extent that cannot be fully predicted. The contracts included
in the trust may be prepaid, in full or in part, voluntarily or as a result of
defaults, theft of or damage to the related vehicles or other reasons. Onyx will
be required to repurchase a contract from the seller, and the seller will be
required to repurchase a contract from the trust, if Onyx breached its
representations and warranties with respect to the contract in the sale and
servicing agreement with the seller. Onyx, in its capacity as servicer, will
also be required to purchase a contract from the trust if it breaches its
servicing obligations with respect to the contract and the contract is
materially and adversely affected by the breach. The purchase will also be
entitled to purchase all of the remaining contracts from the trust once the
aggregate principal balance of the contracts is 10% or less than the aggregate
principal balance of the contracts as of their applicable cut-off date.

         The rate of payment of principal on each class of notes and the
certificates depends primarily on the rate of payments, including prepayments,
on the principal balance of the contracts. As a result, final payment on any
class of securities could occur significantly earlier than the applicable final
scheduled distribution date.

         Onyx cannot predict the actual prepayment rates that will occur on the
contracts in either stable or changing interest rate environments. See "-
Limited Operating History of Onyx". Moreover, many other factors will affect the
amount and timing of payments of principal on each class of securities. The
factors include:

     -    the level of delinquencies, defaults and losses on the contracts;

     -    the payment of any principal on the notes on an accelerated basis; and

     -    the payment of any accelerated amounts on the notes or the
          certificates following an event of default under the indenture.

         You will bear all the reinvestment risks relating to prepayments on the
Contracts and resulting from distributions of principal on the securities. These
reinvestment risks include the possibility that you may not be able to reinvest
distributions of principal in alternative comparable investments having similar
yields. See "Maturity and Prepayment Considerations" in this prospectus
supplement and in the prospectus.

YOU MAY SUFFER LOSSES IF THE CREDIT ENHANCEMENT PROVIDED FOR THE SECURITIES IS
NOT ADEQUATE.

         If the contracts experience higher rates of delinquencies, defaults and
losses than initially anticipated in connection with the rating of the
securities, amounts available from credit enhancement may not be adequate to
cover the resulting delays or shortfalls in distributions to you.

         The policy provided by [insurer] will provide credit enhancement for
the securities. Additional credit enhancement, which will be used prior to the
policy, will be provided by the following:

     -    in the case of the notes, the subordination of the certificates to the
          notes;

     -    the excess, if any, of -

          -    the amount of interest collected on the contracts in each
               collection period

          over

          -    the amount of interest accruing and payable on the notes and the
               certificates and the amount of the fees of the servicer, the
               indenture trustee, the owner trustee and the trust agent payable
               on the related distribution date; and

     -    amounts available in the spread account, as described under
          "Description of the Transfer and Servicing Agreements - Payment
          Priorities of the Notes and Certificates; The Spread Account" and
          "-Withdrawals from the Spread Account" in this prospectus supplement.

         If the amounts available from this additional credit enhancement are
inadequate, you will bear the risk of any delays and losses resulting from the
delinquencies, defaults and losses on the contracts, unless the delays or losses
are covered by the policy and paid by [insurer]. The policy guarantees payment
of principal of each class of notes and of the certificates only on the
applicable final scheduled distribution date.

         The amount required to be maintained in the spread account is subject
to change as described under "Description of the Transfer and Servicing
Agreements - Payment Priorities of the Notes and Certificates; The Spread
Account" in this prospectus supplement.

PRIORITY OF PAYMENT AND SUBORDINATION INCREASE THE RISK OF LOSS OR DELAY IN
PAYMENT FOR HOLDERS OF THE CLASS A-2 NOTES, CLASS A-3 NOTES, CLASS A-4 NOTES AND
CERTIFICATES.

         Because payments of principal will be applied first to the Class A-1
Notes, then to the Class A-2 Notes, then to the Class A-3 Notes, and then to the
Class A-4 Notes, in the event


                                      S-13

<PAGE>   94
[insurer] defaults under the policy after one or more classes of notes have been
fully or partially repaid and before the other classes of notes with a higher
numerical designation have been fully repaid, delinquencies, defaults and losses
experienced on the contracts will have a disproportionately greater effect on
the notes with a higher numerical designation. Other than in the case of an
event of default under the indenture:

          -    no principal will be paid to the holders of Class A-2 Notes, the
               Class A-3 Notes or the Class A-4 Notes until the principal amount
               of the Class A-1 Notes has been reduced to zero;

          -    no principal will be paid to the holders of the Class A-3 Notes
               or the Class A-4 Notes until the principal amount of the Class
               A-2 Notes has been reduced to zero; and

          -    no principal will be paid to the holders of the Class A-4 Notes
               until the principal amount of the Class A-3 Notes has been
               reduced to zero.

         Distributions of interest on the certificates will be subordinated in
priority of payment to interest due on the notes and, on the final scheduled
distribution date for a class of notes, to principal then due on that class of
notes. Distributions of principal on the certificates will be subordinated to
payment of interest and principal due on the notes. Consequently, the
certificateholders will not receive any interest on a distribution date until
the full amount of interest on the notes due on the distribution date has been
paid and, if the distribution date is on or after the final scheduled
distribution date for a class of notes, until all principal of that class of
notes has been paid in full. No principal will be distributed on the
certificates until all of the notes have been paid in full.

         In the event of a default by [insurer], the certificates will be more
sensitive than the notes to delinquencies, defaults and losses experienced on
the contracts. See "Description of the Notes - Payments of Principal" in this
prospectus supplement.

GEOGRAPHIC CONCENTRATION MAY ADVERSELY AFFECT THE PERFORMANCE OF THE CONTRACTS.

         Economic conditions in the states where the obligors under the
contracts live and work may affect the delinquency, loan loss and repossession
experience of the trust with respect to the contracts. Initial contracts
representing approximately ___% of the initial contracts as of _______, 2000
were originated in California. As of ________, 2000, the aggregate principal
balances of initial contracts originated in any single state other than
California did not exceed ____% of the aggregate principal balance of the
initial contracts on that date. The geographic concentration of all of the
contracts as of the closing date, including both the initial contracts and the
additional contracts purchased by the trust, will be substantially similar to
that of the initial contracts. Adverse economic conditions or other factors
particularly affecting California or other states in which the contracts are
geographically concentrated might adversely affect the


                                      S-14

<PAGE>   95


performance of the contracts. See "The Contracts -- Geographic Concentration of
the Initial Contracts" in this prospectus supplement.


YOU MAY SUFFER LOSSES DUE TO THE LIMITED ASSETS OF THE TRUST.

         You may suffer a loss on your securities if the assets of the trust are
insufficient to pay fully the principal amount of the securities. The trust does
not have, nor is it permitted or expected to have, any significant assets or
sources of funds other than the contracts. You must rely upon payments on the
contracts, amounts, if any, on deposit in the spread account, and payments of
claims made under the policy for repayment of the securities.

         The policy will guarantee:

          -    shortfalls in the payment of accrued interest on each
               distribution date; and

          -    the ultimate repayment of principal on the final scheduled
               distribution date with respect to each security.

However, if [insurer] defaults in its obligations under the policy, the trust
will have to depend solely on collections on the contracts and amounts, if any,
on deposit in the spread account to make payments then due on the securities.
See "Description of the Insurer" and "The Policy" in this prospectus supplement.

DOWNGRADING OF THE RATING OF THE [INSURER] OR THE SECURITIES MAY HAVE AN ADVERSE
AFFECT ON THE LIQUIDITY AND MARKET VALUE OF THE SECURITIES.

         On the closing date, the securities will be rated "AAA" by Standard &
Poor's and "Aaa" by Moody's. 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. Any rating agency rating the securities may lower or
withdraw its rating if, in the sole judgment of the rating agency, circumstances
in the future so warrant. For example, the downgrading of the rating of
[insurer] may affect the ratings on the securities. We cannot predict with
certainty what effect any revision or withdrawal of a rating of the securities
may have on the liquidity or market value of the securities. The ratings of the
securities address the likelihood of timely payment of accrued interest, and
ultimate payment of principal on the applicable final scheduled distribution
dates, which are guaranteed by [insurer] under the policy. The ratings of the
securities are substantially based on the issuance of the policy by [insurer],
and are dependent on the rating of [insurer]. See "Description of the Insurer"
in this prospectus for a description of [insurer]'s rating.

PREPAYMENTS, POTENTIAL LOSSES AND CHANGES IN ORDER OF PRIORITY OF PRINCIPAL
PAYMENTS MAY RESULT FROM AN EVENT OF DEFAULT UNDER THE INDENTURE.

         An event of default under the indenture may result in payments on the
notes being accelerated. As a result -

          -    you may suffer losses on your notes or certificates if the assets
               of the trust are insufficient to pay the amounts owed on the
               notes and certificates;

          -    payments on your notes or certificates may be delayed until more
               senior classes of notes are repaid; and

          -    your notes or certificates may be repaid earlier than as
               scheduled, which may require you to reinvest your principal at a
               lower rate of return.

         ONLY INSURER CAN DECLARE AN EVENT OF DEFAULT IF INSURER IS NOT IN
DEFAULT. Prior to a default by [insurer], only [insurer] can declare an event of
default under the indenture. If [insurer] has defaulted in its obligations under
the policy and continues to be in default, then either the indenture trustee or
the noteholders can declare an event of default under the indenture.

         INSURER CONTROLS REMEDIES IF INSURER IS NOT IN DEFAULT. If an event of
default under the indenture occurs and [insurer] is not in default under the
policy, [insurer] may, but is not obligated to, declare that the notes become
immediately due and payable. In this event, [insurer] will have the right to
control the exercise of remedies available with respect to the event of default,
including the right to direct the indenture trustee to liquidate the property of
the trust on any date or dates following the acceleration of the notes due to
the event of default. Liquidation will result in redemption of the securities.
[Insurer] may not, however, cause the indenture trustee to liquidate the
property of the trust if the proceeds of the liquidation would not be enough to
pay all outstanding principal and accrued interest on the notes. Following an
event of default under the indenture, the indenture trustee and the owner
trustee will continue to submit claims under the policy for any shortfalls in
amounts needed to make payments or distributions of guaranteed amounts on the
securities. However, in this event, [insurer], at its sole option, may elect to
pay all or any portion of the outstanding amount of the securities, plus accrued
interest to the date of payment.

         THE ABILITY OF NOTEHOLDERS TO LIQUIDATE THE TRUST MAY BE LIMITED. If an
event of default under the indenture occurs and [insurer] is in default under
the policy, the noteholders will be able to declare that the notes become
immediately due and payable. In this instance, the noteholders will have the
right to control the exercise of remedies available, including the right to
direct the indenture trustee to liquidate the property of the trust. However,
the noteholders may not direct the indenture trustee to liquidate the property
of the trust unless -


                                      S-16

<PAGE>   97




          (1)  [insurer] has failed to make a payment required under the policy
               and the event of default under the indenture is a result of
               either -

               -    a default in the payment of any principal on the final
                    scheduled distribution date for a class of notes or a
                    default of at least five days in the payment of any interest
                    on any notes; or

               -    certain events of bankruptcy, insolvency, receivership or
                    liquidation of the trust;

          or

          (2)  [insurer] has not failed to make a payment required under the
               policy, the event of default has occurred other than as described
               above, and either --

               -    the proceeds of a liquidation of the trust property will be
                    sufficient to pay all outstanding principal of the notes and
                    the certificates, together with accrued interest, and all
                    amounts due to [insurer] under the insurance agreement; or

               -    holders of certificates evidencing 100% of the outstanding
                    principal amount of the certificates consent to the
                    liquidation of the trust property and all amounts owing to
                    [insurer] under the insurance agreement will be paid in
                    connection with the liquidation.

         In the event of a sale of the contracts as described in alternative (2)
above, the policy will not be available to cover losses to securityholders
resulting from the liquidation of the trust property. The policy will be
terminated, and [insurer] will have no further obligation to make any payment
thereunder.

         NOTEHOLDERS MAY BE ABLE TO CAUSE LIQUIDATION OF THE TRUST WITHOUT
CONSIDERATION OF THE CERTIFICATEHOLDERS. If an event of default under the
indenture occurs as described in alternative (2) above, then the noteholders may
cause a sale of the contracts without the consent of any of the
certificateholders. In determining whether or not to cause a sale of the
contracts, the noteholders do not need to consider whether the proceeds of the
sale will be sufficient to pay any portion of the principal and accrued interest
payable on the certificates. Upon a sale of the contracts by the indenture
trustee in this situation, if the proceeds from the sale and any amounts on
deposit in the spread account and the collection account are not sufficient to
pay all the notes in full, then:

          -    the amount of principal paid to noteholders will be reduced;

          -    no proceeds or amounts will be distributed to the
               certificateholders; and



                                      S-17

<PAGE>   98
          -    the noteholders and the certificateholders will incur a loss on
               their investment.

         If the proceeds from the sale and amounts available in the spread
account and the collection account are sufficient to pay all the notes in full
but are not sufficient to pay both the notes and the certificates in full, then:

          -    the amount of principal distributed to certificateholders will be
               reduced; and

          -    the certificateholders will incur a loss on their investment.

See "The Indenture - Indenture Events of Default" in the prospectus.

IF THERE IS A SERVICER DEFAULT, THE SERVICER MAY BE REMOVED ONLY BY THE INSURER
OR THE INDENTURE TRUSTEE AND THE NOTEHOLDERS.

         If the servicer is in default under the sale and servicing agreement,
only [insurer] may terminate the servicer for the default, unless [insurer] is
in default under the policy. If the servicer is in default under the sale and
servicing agreement and [insurer] is in default under the policy, the
noteholders, or the indenture trustee acting only on behalf of the noteholders,
without regard to the interests of the seller or the certificateholders, may
terminate the servicer. In these circumstances, the certificateholders will not
have the ability to remove the servicer if the servicer is in default until the
notes have been paid in full. In addition, if [insurer] is in default under the
policy, the noteholders may waive certain defaults by the servicer. The
noteholders are not required to consider the effect any waiver would have on the
certificateholders. See "- Certain Matters Regarding the Insurer" and
"Description of the Transfer and Servicing Agreements - Servicer Default; Rights
Upon Servicer Default" in this prospectus supplement.

IF PROBLEMS ASSOCIATED WITH THE YEAR 2000 PROBLEM WERE TO OCCUR, YOU COULD
EXPERIENCE DELAYS OR SHORTFALLS IN PAYMENTS DUE ON THE SECURITIES.

         Historically, many information technology systems were developed to
recognize the year as a two-digit number, with the digits "00" being recognized
as the year 1900. The year 2000 presents a number of potential problems for
these systems, including potentially significant processing errors or failures.
Onyx has developed and executed a comprehensive plan designed to address the
year 2000 problem for its in-house and third party information technology
applications. Onyx completed its year 2000 testing in 1999 and has experienced
no problems related to the year 2000 problem. However, there can be no assurance
that all potential year 2000 problems have been identified and corrected.
Accordingly, you could be adversely affected if the information technology
systems of Onyx are not fully year 2000 compliant and that non-compliance
disrupts the collection or distribution of collections on the contracts.

         With respect to the year 2000 problem, DTC has informed members of the
financial community that it has developed and is implementing a program so that
its systems, as they relate to timely payment of distributions, including
principal and interest payments, to holders of securities, book-entry
deliveries, and settlement of trades within DTC, continue to function

                                      S-18

<PAGE>   99

appropriately on and after January 1, 2000. This program includes a technical
assessment and a remediation plan, each of which is complete. Additionally,
DTC's plan includes a testing phase, which is expected to be completed within
appropriate time frames.

         However, DTC's ability to perform properly its services is also
dependent upon other parties, including but not limited to its participating
organizations, through which you will hold your securities, as well as computer
systems of third party service providers. DTC has informed the financial
community that it is contacting and will continue to contact third party vendors
from whom DTC acquires services to impress upon them the importance of those
services being year 2000 compliant and to determine the extent of their efforts
for year 2000 remediation, and, as appropriate, testing, of their services.

         In addition, DTC has stated that it is in the process of developing
those contingency plans as it deems appropriate. If problems associated with the
year 2000 problem were to occur with respect to DTC and the services described
above, you could experience delays or shortfalls in payments due on the
securities.

THE INSURER HAS THE RIGHT TO EXERCISE ALL RIGHTS OF THE SECURITYHOLDERS UNDER
THE SALE AND SERVICING AGREEMENT, THE INDENTURE AND THE TRUST AGREEMENT.

         So long as [insurer] is not in default under the policy, it will have
the right to exercise all rights, including voting rights, which the
securityholders are entitled to exercise under the sale and servicing agreement,
the indenture and the trust agreement. However, [insurer] cannot exercise the
securityholders' rights to amend the sale and servicing agreement, the indenture
or the trust agreement, without the consent of each holder of a note,
certificate or residual interest affected by the amendment, in any manner that
would:

          -    reduce the amount of, or delay the timing of, collections of
               payments of monthly principal and interest on the contracts or
               distributions required to be made on any security;

          -    adversely affect in any material respect the interests of the
               holders of any class of notes or the certificates; or

          -    alter the rights of any such securityholder to consent to an
               amendment.

         If [insurer] is in default under the policy, it cannot take any action
under the sale and servicing agreement, the indenture or the trust agreement, to
terminate the servicer, or to control or direct the actions of the trust, the
seller, the servicer, the indenture trustee, the owner trustee or the trust
agent under the terms of the sale and servicing agreement, the indenture or the
trust agreement. Furthermore, the consent of [insurer] will not be required with
respect to any action, or waiver of a right to take action, to be taken by the
trust, the seller, the servicer, the indenture trustee, the owner trustee, the
trust agent or the securityholders; except that, the consent of [insurer] is
required at all times to amend the sale and servicing agreement, the indenture
and the trust agreement.

                                    THE TRUST

GENERAL
         The trust is a business trust formed under the laws of the State of
Delaware under the trust agreement for the transactions described in this
prospectus supplement. The trust will not engage in any activity other than:

          -    acquiring, holding and managing the contracts and the other
               assets of the trust and proceeds therefrom;

          -    issuing the notes and the certificates;

          -    making payments and distributions on the notes and the
               certificates; and

          -    engaging in other activities that are necessary, suitable or
               convenient to accomplish the foregoing or are incidental thereto

                  THE ONYX PORTFOLIO OF MOTOR VEHICLE CONTRACTS

PURCHASE, ORIGINATION AND SERVICING OF MOTOR VEHICLE CONTRACTS

         Onyx's purchase and origination of motor vehicle contracts are
described under the heading "The Onyx Portfolio of Motor Vehicle Contracts -
Purchase and Origination of Motor Vehicle Contracts" in the prospectus. At
______, 200__, Onyx had agreements with approximately ___ dealers, of which
approximately ___% are franchised new car dealerships and approximately ___% are
independent used car dealerships. All of the contracts will have been sold to
the seller and then to the trust.

         Onyx, together with its subsidiaries, had acquired or originated motor
vehicle contracts totaling approximately $___ billion from commencement of
operations through _________. As of _________, Onyx had amassed a servicing
portfolio of approximately $___ billion. As of _______, approximately ____% of
Onyx's servicing portfolio consisted of motor vehicle contracts secured by used
motor vehicles, and ___% secured by new motor vehicles. As of ________, Onyx had
total assets of approximately $____ million and stockholder's equity of $___
million.

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 an annual
basis commencing December 31, 1996. 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 purchased or originated by a subsidiary of
Onyx, 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. Accordingly, Onyx has
historical performance for only a limited time period with respect to the motor
vehicle contracts it purchases and originates and, consequently, 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" in this
prospectus supplement and in the prospectus.

         With the continued expansion of Onyx in the eastern United States and
the significant growth in Onyx's existing branches, Onyx has centralized and
improved its servicing and collection process. Onyx believes that a centralized
group is efficient and effective, and assures


                                      S-21

<PAGE>   102
that collection practices and policies are applied consistently throughout the
company. Management continues to rely on the use of current technology such as
predictive dialers utilizing an automated processing system for contacting
delinquent borrowers. Onyx also has a payment system that allows electronic
payment on delinquent accounts to be applied the same day as payment is sent or
initiated by the borrower.

                                  THE CONTRACTS

         All of the contracts will have been purchased by the seller from Onyx.
Substantially all of the contracts have been purchased by Onyx from new and used
car dealers unaffiliated with Onyx or the seller, and a limited number of
contracts will have been purchased or originated by subsidiaries of Onyx. See
"The Onyx Portfolio of Motor Vehicle Contracts" in this prospectus supplement
and in the prospectus. Each of the contracts in the trust will be a fixed rate
contract where the allocation of each payment between interest and principal is
calculated using the rule of 78's method, actuarial method or the simple
interest method. Each of these methods is explained under the heading "The Onyx
Portfolio of Motor Vehicle Contracts - Allocation of Payments on Contracts to
Interest and Principal" in the prospectus. Initial contracts representing
approximately _______% of the Initial Cut-Off Pool Balance allocate interest and
principal in accordance with the rule of 78's or the actuarial method, and
initial contracts representing approximately ______% of the Initial Cut-Off Pool
Balance allocate interest in accordance with the simple interest method.


         The contracts will have been selected from the motor vehicle contracts
in the portfolio of Onyx using the following criteria. No selection procedures
will have been used with respect to the contracts that are believed by Onyx or
the seller to be adverse to the securityholders or [insurer]. Initial contracts
representing approximately ______% of the Initial Cut-Off Pool Balance are
secured by new vehicles, and initial contracts representing approximately
______% of the Initial Cut-Off Pool Balance are secured by used vehicles. The
seller may not substitute other motor vehicle contracts for the contracts at any
time during the term of the sale and servicing agreement.

         The seller will represent that each contract included in the trust
satisfies the following eligibility requirements:

          -    the contract is secured by a new or used automobile, light-duty
               truck or van;

          -    the contract has a remaining maturity as of the Cut-Off Date of
               not more than ___ months;

          -    the contract has an original maturity of not more than ___
               months;

          -    the contract is a fully-amortizing fixed rate contract which
               provides for level scheduled monthly payments determined on the
               basis of the rule of 78's, actuarial or the simple interest
               method, except for the last payment, which may be minimally
               different from the level payments;

          -    the contract is secured by a vehicle that as of the Cut-Off Date
               has not been repossessed without reinstatement;

          -    the contract has no payment more than ___ days past due as of the
               Cut-Off Date;


                                      S-23

<PAGE>   104



          -    the contract has a remaining principal balance as of the Cut-Off
               Date of at least $___________; and

          -    as of the Cut-Off Date, the seller has not received notice that
               the related obligor has filed for bankruptcy.

         Set forth below is data concerning the initial contracts as of the
Initial Cut-Off Date which had an aggregate principal balance as of the Initial
Cut-Off Date of $___________. Data concerning all of the contracts (both the
initial contracts and the Subsequent Contracts) will be available to purchasers
of the securities at or before the initial delivery of the securities and will
be filed with the SEC on Form 8-K within 15 days after the initial delivery of
the securities. While the financial and other data for the Subsequent Contracts
will differ somewhat from the data for the initial contracts, the
characteristics of the contracts as a whole will not vary materially from the
characteristics of the initial contracts described below.

                     MATURITY AND PREPAYMENT CONSIDERATIONS

         The contracts are or will be prepayable in full by the obligors at any
time without penalty. See "Maturity and Prepayment Considerations" in the
prospectus regarding the effects of prepayments on the weighted average life of
the contracts. As the rate of payment of principal of each class of notes and
the certificates depends primarily on the rate of payment, including
prepayments, of the principal of the contracts, final payment of any class of
notes or of the certificates is expected to occur earlier, and could occur
significantly earlier, than the respective final scheduled distribution date for
the securities.

         All full and partial prepayments on simple interest contracts and all
full prepayments on rule of 78's and actuarial contracts will be paid to
securityholders on the distribution date immediately following the calendar
month in which the prepayments are received. Accordingly, the prepayments will
shorten the average life of those contracts, and, therefore, of the securities.
Partial prepayments on rule of 78's and actuarial contracts are treated as
payments in advance and, accordingly, will not affect the average life of the
contracts. The obligors can prepay the contracts in full at any time without
penalty.

         Onyx can make no prediction as to the actual prepayment rates that will
be experienced on the contracts in either stable or changing interest rate
environments. In addition, the rate of payment of principal of each class of
securities will be affected by the incidence of delinquencies, defaults and
losses, by the application of the Accelerated Principal Distributable Amount to
pay the principal of the notes, and by any accelerated payments made on the
securities following an event of default under the indenture. See "Risk Factors
- - Maturity and Prepayment Considerations" in this prospectus supplement.

                                 USE OF PROCEEDS

         The net proceeds of the initial sale of the securities will be used by
the trust to purchase the contracts from the seller under the sale and servicing
agreement and to fund the deposits in the collateral accounts maintained for the
benefit of the securityholders and the insurer. The net proceeds to be received
by the seller from the sale of the contracts to the trust will be used by the
seller to repay some or all of the indebtedness incurred, or to pay other
amounts owed, in connection with its acquisition of the contracts and to pay
other expenses in connection with the pooling of the contracts and the issuance
of the securities.


                            DESCRIPTION OF THE NOTES

         The notes will be issued under the terms of the indenture, a form of
which will be filed with the SEC following the issuance of the notes. The
following summaries describe the material terms of the notes and the indenture,
but do not purport to be complete and are subject to, and qualified in their
entirety by reference to, the provisions of the notes and the indenture. Where


                                      S-27

<PAGE>   108



particular provisions of or terms used in the indenture are referred to, the
actual provisions, including definitions of terms, are incorporated by reference
as part of the summaries. The following summaries of terms of the indenture
supplement, and to the extent inconsistent therewith replace, the description of
the general terms and provisions of the indenture set forth under the heading
"The Indenture" in the prospectus, to which description reference is hereby
made.

PAYMENTS OF INTEREST

         Interest on the outstanding principal amount of each class of notes
will accrue during the Interest Accrual Period at the respective per annum
interest rates for the various classes of notes and will be payable to the
noteholders on each distribution date, commencing ________, 2000. Interest
accrued but not paid on any distribution date will be due on the immediately
succeeding distribution date, together with, to the extent permitted by
applicable law, interest on the shortfall at the related interest rate. Interest
on the notes will be calculated on the basis of a 360-day year of twelve 30-day
months, with the exception of the Class A-1 Notes, with respect to which
interest will be calculated on the basis of a 360-day year and the actual number
of days in the related Interest Accrual Period. Interest payments on the notes
will be made as described below under "Description of the Transfer and Servicing
Agreements - Distributions" in this prospectus supplement.

PAYMENTS OF PRINCIPAL

         Principal payments will be made to the noteholders, to the extent
described below, on each distribution date in an amount equal to the Note
Principal Distributable Amount as described below under "Description of the
Transfer and Servicing Agreements - Distributions" in this prospectus
supplement.

         Principal payments on the notes will be applied on each distribution
date from the Note Distribution Account -

          -    first, to the holders of the Class A-1 Notes until the principal
               amount of the Class A-1 Notes has been reduced to zero;

          -    second, to the holders of the Class A-2 Notes until the principal
               amount of the Class A-2 Notes has been reduced to zero;

          -    third, to the holders of the Class A-3 Notes until the principal
               amount of the Class A-3 Notes has been reduced to zero; and

          -    fourth, to the holders of the Class A-4 Notes until the principal
               amount of the Class A-4 Notes has been reduced to zero.



                                      S-28

<PAGE>   109



The Note Principal Distributable Amount for each distribution date will include
an amount equal to the Accelerated Principal Distributable Amount for that
distribution date, if any. See "Description of the Transfer and Servicing
Agreements - Distributions" in this prospectus supplement.

         After the principal amount of the Class A-4 Notes has been reduced to
zero, the Regular Principal Distributable Amount will be allocated to the
certificates.

         The principal amount of each class of notes, to the extent not
previously paid, will be due on the final scheduled distribution date for that
class of notes. The actual date on which the outstanding principal amount of any
class of notes is paid is expected to be earlier, and could be significantly
earlier, than the final scheduled distribution date for that class based on a
variety of factors, including the factors described under "Maturity and
Prepayment Considerations" in this prospectus supplement and in the prospectus.

MANDATORY PARTIAL REDEMPTION

         The Class A-1 Notes will be subject to mandatory partial redemption on
the first distribution date if and to the extent that the amount of proceeds
from the sale of the securities exceeds the Original Pool Balance. In this
event, the holders of Class A-1 Notes will receive, on the first distribution
date, an amount paid in respect of principal equal to the excess.

OPTIONAL REDEMPTION

         Each class of outstanding notes will be subject to redemption in whole,
but not in part, on any distribution date on which the principal balance of the
contracts has declined to 10% or less of the Original Pool Balance. The
redemption price for each class of notes will equal the unpaid principal amount
of that class of notes plus accrued and unpaid interest thereon at the
applicable interest rate. Any redemption will effect early retirement of each
class of notes. See "Description of the Transfer and Servicing Agreements -
Termination" in this prospectus supplement.

THE INDENTURE TRUSTEE

         [________________] will be the indenture trustee. The indenture trustee
is a New York banking corporation and its Corporate Trust Office is located at
________________.

         The indenture trustee will have the rights and duties set forth under
"Description of the Transfer and Servicing Agreements - The Trustee and the
Indenture Trustee" in the prospectus.

INDENTURE EVENTS OF DEFAULT

         Those events which constitute a default by the indenture trustee under
the indenture are set forth under "The Indenture - Indenture Events of Default"
in the prospectus. Upon an event of


                                      S-29

<PAGE>   110


default under the indenture, the insurer and the noteholders will have the
rights set forth in the prospectus under "The Indenture - Rights Upon Indenture
Event of Default."


                         DESCRIPTION OF THE CERTIFICATES

         The certificates will be issued under the trust agreement, a form of
which will be filed with the SEC following the issuance of the certificates. The
following summaries, together with the referenced sections of the prospectus,
describe the material terms of the certificates and the trust agreement, but do
not purport to be complete and are subject to, and qualified in their entirety
by reference to, the provisions of the certificates and the trust agreement.
Where particular provisions of or terms used in the trust agreement are referred
to, the actual provisions, including definitions of terms, are incorporated by
reference as part of the summaries.

DISTRIBUTIONS OF INTEREST

         Interest on the outstanding principal balance of the certificates will
accrue during the Interest Accrual Period at the per annum interest rate for
certificates and will be payable to the certificateholders on each distribution
date, commencing ________, 2000. Interest accrued but not paid on any
distribution date will be due on the immediately succeeding distribution date,
together with, to the extent permitted by applicable law, interest on the
shortfall at the related interest rate. Interest on the certificates will be
calculated on the basis of a 360-day year of twelve 30-day months. Interest
distributions with respect to the certificates will be made as described below
under "Description of the Transfer and Servicing Agreements - Distributions" in
this prospectus supplement.

DISTRIBUTIONS OF PRINCIPAL

         No principal will be paid on the certificates until the principal
amount of all of the notes have been paid in full. On each distribution date on
and after the notes have been paid in full, the certificateholders will be
entitled to distributions in an amount equal to the Certificate Principal
Distributable Amount as described below under "Description of the Transfer and
Servicing Agreements - Distributions" in this prospectus supplement. The
Accelerated Principal Distributable Amount will not be included in the
Certificate Principal Distributable Amount.

         The remaining outstanding principal balance of the certificates, to the
extent not previously paid, will be payable on the final scheduled distribution
date for the certificates. The actual date on which the principal balance of the
certificates is reduced to zero is expected to be earlier, and could be
significantly earlier, than the final scheduled distribution date for the
certificates based on a variety of factors, including the factors described
under "Maturity and Prepayment Considerations" in this prospectus supplement and
in the prospectus.



                                      S-30

<PAGE>   111
OPTIONAL PREPAYMENT

         The certificates will be subject to prepayment in whole, but not in
part, on any distribution date on which the principal balance of the contracts
has declined to 10% or less of the Original Pool Balance. Certificateholders
will receive an amount in respect of the certificates equal to the outstanding
principal balance of the certificates plus accrued and unpaid interest thereon
at the interest rate for the certificates. This prepayment will effect early
retirement of the certificates. See "Description of the Transfer and Servicing
Agreements - Termination" in this prospectus supplement.

PAYING AGENT

         Distributions of principal of and interest on the certificates will be
made by the trust agent or any paying agent or paying agents as the owner
trustee may designate from time to time. The trust agent will be designated as
the initial paying agent with respect to the certificates.


              DESCRIPTION OF THE TRANSFER AND SERVICING AGREEMENTS


         The following summary, together with the information set forth in the
accompanying prospectus, describes the material terms of the sale and servicing
agreement and the trust agreement. Forms of the sale and servicing agreement and
the trust agreement will be filed with the SEC following the issuance of the
securities. The summary does not purport to be complete and is subject to, and
qualified in its entirety by reference to, all the provisions of those
agreements. The following summary supplements the description of the general
terms and provisions of the transfer and servicing agreements set forth under
the heading "Description of the Transfer and Servicing Agreements" in the
prospectus, to which description reference is hereby made.


SALE AND ASSIGNMENT OF THE CONTRACTS

         At the time of issuance of the securities, the seller will sell and
assign to the trust, without recourse, the seller's entire interest in the
contracts and the proceeds thereof, including its security interests in the
financed vehicles. Each contract will be identified in a schedule appearing as
an exhibit to the sale and servicing agreement. Concurrently with this sale and
assignment, the trust will pledge the assets acquired by it to the indenture
trustee under the indenture, and the notes and the certificates will be
delivered to the underwriters against payment to the seller of the net purchase
price of the sale of the securities. Before the sale of the contracts to the
trust and the issuance of the securities, each of Onyx's participating
subsidiaries will sell and assign to Onyx under a purchase agreement, without
recourse, its entire interest in the contracts, and Onyx will sell and assign to
the seller its entire interest in the contracts. See "Description of the
Transfer and Servicing Agreements - Sale and Assignment of the Contracts" in the
prospectus.

THE ACCOUNTS

         THE COLLECTION, PAYAHEAD AND PAYMENT ACCOUNTS. The collection account
and the payahead account referred to in the prospectus under "Description of the
Transfer and Servicing Agreements - The Collection Account and Eligible
Investments" and "- Payahead Account" will be established by the servicer and
maintained by a financial institution acceptable to the indenture trustee and
the insurer in the name of the indenture trustee. The indenture trustee will
establish and maintain a payment account, in the name of the indenture trustee,
into which amounts released from the collection account for distribution to
securityholders will be deposited prior to transfer of those amounts to the
distribution accounts described below.

         THE DISTRIBUTION ACCOUNTS. The servicer will establish and maintain
with the indenture trustee the following distribution accounts:

          -    a note distribution account, in the name of the indenture trustee
               on behalf of the noteholders, in which amounts released from the
               payment account for distribution to noteholders will be deposited
               and from which all distributions to noteholders will be made; and

          -    a certificate distribution account, in the name of the trust
               agent on behalf of the certificateholders, in which amounts
               released from the payment account for distribution to
               certificateholders will be deposited and from which all
               distributions to certificateholders will be made.

         THE SPREAD ACCOUNT. The spread account will be established and
maintained as described under "Description of the Transfer and Servicing
Agreements - Payment Priorities of the Notes and Certificates; The Spread
Account" and "- Withdrawals from the Spread Account" in this prospectus
supplement.

PAYMENTS ON CONTRACTS

         Net 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. Net collections with respect to a distribution date
and the related Collection Period will include:

          -    amounts received with respect to the contracts in the Collection
               Period representing monthly installments of principal and
               interest;

          -    full prepayments and partial prepayments, pending transfer of
               partial prepayments on any rule of 78's or actuarial contracts to
               the payahead account;

          -    Net Liquidation Proceeds and Net Insurance Proceeds;



                                      S-32

<PAGE>   113
          -    any amounts deposited by Onyx or the seller in the collection
               account to purchase contracts because of material defects in
               documents related to the contracts or breaches of representations
               or warranties regarding the contracts made by the seller in the
               sale and servicing agreement that materially and adversely affect
               the interests of the securityholders or the insurer;

          -    any amounts deposited by the servicer in the collection account
               to purchase contracts as to which the servicer has breached its
               servicing covenants; and

          -    any amounts deposited by the servicer in the collection account
               as a result of the servicer exercising its right to purchase all
               or a portion of the contracts.

         Partial prepayments of rule of 78's and actuarial contracts are
initially deposited in the collection account and are transferred to the
payahead account on the Servicer Report Date.

DISTRIBUTIONS

         On the business day immediately preceding each distribution date, the
servicer will cause funds equal to the amount of net collections available with
respect to that distribution date to be withdrawn from the collection account
and deposited into the payment account. On each distribution date, the indenture
trustee will apply the net collections on deposit in the payment account
available with respect to the related Collection Period together with amounts,
if any, withdrawn from the spread account or representing payment of the Policy
Claim Amount, to make the following deposits and distributions in the following
amounts and order of priority:

          (1)  to the servicer, the servicing fee, including any accrued and
               unpaid servicing fees with respect to one or more prior
               Collection Periods;

          (2)  to the indenture trustee, the owner trustee and the trust agent,
               any accrued and unpaid fees of the indenture trustee, the owner

               have not been previously paid by the servicer;

          (3)  to the note distribution account, the Note Interest Distributable
               Amount to be paid to the holders of the notes at their respective
               interest rates;

          (4)  to the Note Distribution Account, if the distribution date is a
               final scheduled distribution date for any class of notes, the
               Note Principal Distributable Amount to the extent of the
               remaining principal amount of that class of notes, to be paid to
               the holders of that class of notes;

          (5)  to the certificate distribution account, the Certificate Interest
               Distributable Amount, to be distributed to the holders of the
               certificates;

                    zero;

               -    second, to the holders of the Class A-2 Notes until the
                    principal amount of the Class A-2 Notes has been reduced to
                    zero;

               -    third, to the holders of the Class A-3 Notes until the
                    principal amount of the Class A-3 Notes has been reduced to

               -    fourth, to the holders of the Class A-4 Notes until the
                    principal amount of the Class A-4 Notes has been reduced to
                    zero;

          (7)  to the certificate distribution account, if the distribution date
               is the final scheduled distribution date for the certificates,
               the Certificate Principal Distributable Amount to the extent of
               the outstanding principal balance of the certificates, to be
               distributed to the holders of the certificates;

          (8)  to the certificate distribution account, if the distribution date
               is not the final scheduled distribution date for the
               certificates, after giving effect to the distributions described
               in clauses (1) through (6) above, the remaining Certificate
               Principal Distributable Amount to the extent of the outstanding

               to the insurer under the insurance agreement;

               prospectus supplement.



                                      S-34

<PAGE>   115



         If the notes are accelerated following an event of default under the
indenture, amounts collected will be applied -

          -    first, to pay any unpaid servicing fee;

          -    second, to pay any accrued and unpaid fees of the indenture
               trustee, owner trustee and trust agent without preference or
               priority of any kind;

          -    third, to pay accrued interest on each class of notes on a pro
               rata basis based on the interest accrued, including interest
               accrued on past-due interest, on each class of Notes;

          -    fourth, to pay principal on each class of notes, on a pro rata
               basis based on the aggregate principal balance of each class of
               notes, until the aggregate principal balance of each class of
               notes is reduced to zero;

          -    fifth, to pay accrued interest on the certificates, including
               interest on past due interest;

          -    sixth, to pay principal on the certificates until the outstanding
               principal balance of the certificates is reduced to zero;

          -    seventh, to pay amounts owing the insurer under the insurance
               agreement; and

          -    eighth, to the spread account, to be applied in accordance with
               the insurance agreement.

         Amounts on deposit in the spread account on a distribution date will be
available to make payments and distributions on that distribution date as
described under "- Withdrawals from the Spread Account" in this prospectus
supplement.

         Under the policy, the insurer is obligated to provide for payment to
the indenture trustee on each distribution date of any Policy Claim Amount. In
addition, on any distribution date, the insurer may elect, in its sole
discretion, to pay all or a portion of any shortfalls in the amount of net
collections available to distribute the amounts described in clauses (6) and (8)
above. See "The Policy" in this prospectus supplement.

PAYMENT PRIORITIES OF THE NOTES AND THE CERTIFICATES; THE SPREAD ACCOUNT

         The rights of the securityholders to receive distributions with respect
to the contracts will be subordinated to the rights of -

          -    the servicer, to the extent that the servicer has not been paid
               all servicing fees; and



                                      S-35

<PAGE>   116


          -    the indenture trustee, the owner trustee and the trust agent, to
               the extent any of them has not received accrued and unpaid fees
               from the servicer.

         In addition, the rights of the noteholders to receive distributions
with respect to the contracts will be subject to the priorities set forth under
"Description of the Transfer and Servicing Agreements - Distributions" in this
prospectus supplement and the rights of the certificateholders to receive
distributions with respect to the contracts will be subordinated to the rights
of the noteholders, in each case to the extent described above. These priorities
and subordination are intended to enhance the likelihood of timely receipt by
the noteholders of the full amount of interest and principal required to be paid
to them, and to afford the noteholders limited protection against losses in
respect of the contracts.

         The foregoing protection will be effected both by the preferential
right of the noteholders to receive, to the extent described in this prospectus
supplement, current distributions with respect to the contracts, and by the
establishment of the spread account. The spread account will be a part of the
trust and will be a segregated trust account in the name of the indenture
trustee. The indenture trustee will have a perfected security interest in all
amounts deposited in or credited to the spread account as well as all Eligible
Investments. The spread account will be funded by the deposit therein of amounts
under clauses (10) and (11) under "- Distributions" above.

         Amounts held from time to time in the spread account will continue to
be held for the benefit of holders of the securities and the insurer and may be
invested in Eligible Investments. Investment income on monies on deposit in the
spread account will be credited to the spread account. Any loss on the
investment will be charged to the spread account.

         The Spread Account Maximum may increase or decrease over time, without
the consent of any of the securityholders, as a result of floors, caps and
triggers set forth in the insurance agreement. In addition, there can be no
assurance that the Spread Account Maximum will be reached at any given time.
Consequently, securityholders should not rely on amounts on deposit or to be
deposited in the spread account in evaluating the likelihood that the securities
will be repaid.

WITHDRAWALS FROM THE SPREAD ACCOUNT

         Amounts held from time to time in the spread account will continue to
be held for the benefit of the noteholders, the certificateholders and the
insurer. On each distribution date funds will be withdrawn from the spread
account and deposited into the payment account to the extent that the sum of the
amounts set forth in clauses (1) though (5) and (7) under "- Distributions"
above with respect to that distribution date exceeds the amount of net
collections available with respect to that distribution date. Funds will also be
withdrawn from the spread account to reimburse the insurer for any draws under
the policy with respect to any Preference Amount.

         If the amount on deposit in the spread account on any distribution
date, after giving effect to all deposits to and withdrawals from the spread
account on that distribution date, is greater than

                                      S-36

<PAGE>   117



the Spread Account Maximum for that distribution date, then the indenture
trustee will distribute any excess -

          -    first, to the insurer, to the extent of any amounts owing to the
               insurer under the insurance agreement;

          -    second, to the holders of the residual interests in the trust.

Upon any distributions to the insurer or the holders of the residual interests,
the securityholders will have no further rights in, or claims to, such amounts.

         None of the securityholders, the indenture trustee, the owner trustee,
the trust agent, the seller, the insurer or the holders of the residual
interests will be required to refund any amounts properly distributed to them,
whether or not there are sufficient funds on any subsequent distribution date to
make full distributions to the securityholders. The obligations of the insurer
under the policy will not be diminished or otherwise affected by any amounts
distributed to the insurer as described in the preceding paragraph.

SERVICING FEE

         The servicer will be entitled to compensation for the performance of
its obligations under the sale and servicing agreement. The servicer will be
entitled to receive a servicing fee on each distribution date an amount equal to
the product of one-twelfth of 1% per annum multiplied by the aggregate
outstanding balance of the contracts as of the end of the Collection Period
preceding the related 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 of funds credited to the collection account and
the payahead account. The servicer will pay all expenses incurred by it in
connection with its servicing activities under the sale and servicing agreement
and will not be entitled to reimbursement of the expenses except to the extent
they constitute Liquidation Expenses or expenses recoverable under an applicable
insurance policy.

         The sale and servicing agreement requires the servicer to use its best
efforts to collect all payments called for under the terms and provisions of the
contracts. The servicer, consistent with the foregoing, will be permitted, in
its discretion, to waive charges and grant extensions as described under
"Description of the Transfer and Servicing Agreements - Waivers and Extensions"
in the prospectus. The maturity date of a contract, however, may not be extended
more than 120 days past the originally scheduled maturity date, and in no event
beyond the latest final scheduled distribution date for the securities.

SERVICER DEFAULT

         The events which constitute a servicer default under the sale and
servicing agreement are described under "Description of the Transfer and
Servicing Agreements - Servicer Default" in the prospectus. Additionally, the
occurrence of trigger events set forth in the insurance agreement will
constitute a servicer default.

RIGHTS UPON SERVICER DEFAULT

         If a default by the insurer has occurred and is continuing, then upon
the occurrence of a servicer default, the indenture trustee, owner trustee,
noteholders and certificateholders will have the rights described under
"Description of the Transfer and Servicing Agreement - Rights Upon Servicer
Default" in the prospectus. However, if an insurer default shall not have
occurred and be continuing, then only the insurer, and not the indenture
trustee, the noteholders, the owner trustee or the certificateholders, may
terminate the servicer. If the insurer terminates the servicer, the insurer will
appoint a successor servicer who will succeed to all the responsibilities,
duties and liabilities of the servicer under the sale and servicing agreement
and will be entitled to similar compensation arrangements.

WAIVER OF SERVICER DEFAULT

         If a default by the insurer has occurred and is continuing, then upon
the occurrence of a servicer default, the noteholders and the certificateholders
will have the right to waive defaults by the servicer as described under
"Description of the Transfer and Servicing Agreement - Waiver of Servicer
Default" in the prospectus. However, if an insurer default shall not have
occurred and be continuing, then only the insurer, and not the noteholders or
the certificateholders, may waive any default by the servicer in the performance
of its obligations under the sale and servicing agreement and its consequences,
except a servicer default in making any required deposits to or payment from the
trust accounts in accordance with the sale and servicing agreement. No waiver by
the insurer will impair the insurer's or the noteholders' or certificateholders'
rights with respect to subsequent servicer defaults. If an insurer default shall
not have occurred and be continuing, then a servicer default in making any
required deposits to or payment from the trust accounts in accordance with the
sale and servicing agreement may only be waived with the consent of both the
insurer and the holders of 100% of the outstanding principal amount of the notes
or, if the notes have been paid in full, the holders of 100% of the outstanding
principal amount of the certificates.

TERMINATION

         The obligations of the servicer, the seller, the owner trustee and
indenture trustee with respect to the related securityholders under the trust
agreement, sale and servicing agreement or indenture will terminate as described
under "Description of the Transfer and Servicing Agreements - Termination" in
the prospectus, and as set forth below.
                                      S-38

<PAGE>   119




         In order to avoid excessive administrative expenses, the servicer will
be permitted at its option to purchase the remaining contracts from the trust on
any distribution date as of which the aggregate outstanding principal balance of
the contracts has declined to 10% or less of the Original Pool Balance, at a
price equal to the greater of -

          -    the sum of:

               -    the aggregate outstanding principal balance of the contracts
                    on the date of repurchase, plus

               -    accrued and unpaid interest on the contracts; and

          -    the sum of:

               -    the aggregate unpaid principal amount of the securities,
                    plus

               -    accrued and unpaid interest thereon, plus

               -    all amounts due to the insurer under the insurance
                    agreement.

         The trust agent and indenture trustee will give written notice of
termination to each securityholder of record. The final distribution to each
securityholder will be made only upon surrender and cancellation of the holder's
securities at the office or agency of the related trustee specified in the
notice of termination. Any funds remaining in the trust, after the trustee has
taken measures to locate a securityholder and those measures have failed, will
be distributed to a charity designated by the servicer.

         Any outstanding notes will be redeemed concurrently with any purchase
described above, and the subsequent distribution to the related
certificateholders of all amounts required to be distributed to them under the
trust agreement will effect early retirement of the certificates.

PAYMENT IN FULL OF NOTES

         Upon the payment in full of all outstanding notes and the satisfaction
and discharge of the indenture, the owner trustee will succeed to all the rights
of the indenture trustee, and the certificateholders will succeed to all the
rights of the noteholders, under the sale and servicing agreement, except as
otherwise provided therein.

CERTAIN MATTERS RELATING TO THE INSURER

         In the event an insurer default shall have occurred and be continuing,
the insurer shall not have the right to take any action under the sale and
servicing agreement, the indenture or the trust agreement, to terminate the
servicer, or to control or direct the actions of the seller, the servicer,


                                      S-39

<PAGE>   120


the owner trustee or the indenture trustee under the terms of the sale and
servicing agreement, the indenture or the trust 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, the indenture trustee, the
owner trustee, the noteholders, the certificateholders or the residual
interestholders; provided, that the consent of the insurer shall be required at
all times with respect to any amendment of the sale and servicing agreement, the
indenture or the trust agreement.


                                   THE POLICY

         The insurer, in consideration of the payment of the premium and subject
to the terms of the policy, thereby unconditionally and irrevocably guarantees
to any Owner that an amount equal to each Policy Claim Amount will be received
by the indenture trustee, or its successors, as trustee for the Owners, on
behalf of the Owners from the insurer, for distribution by the indenture
trustee, to each Owner of each Owner's proportionate share of the Policy Claim
Amount. The insurer's obligations under the policy with respect to a particular
Policy Claim Amount will be discharged to the extent funds equal to the
applicable Policy Claim Amount are received by the indenture trustee, whether or
not those funds are properly applied by the indenture trustee. Payments of
Policy Claim Amounts will be made only at the time set forth in the policy. The
policy will not guarantee payments of principal on any class of notes or on the
certificates other than the payment of the outstanding principal amount of a
class of notes or of the certificates on the final scheduled distribution date
for that class of notes or the certificates, and will not guarantee payment of
any Accelerated Principal Distributable Amount or any amounts which become due
on an accelerated basis as a result of a default by the trust, the occurrence of
an event of default under the indenture, or any other cause. The insurer may
elect, in its sole discretion, to pay in whole or in part the principal due upon
acceleration. The insurer may elect, in its sole discretion, to pay all or a
portion of shortfalls of funds available to make distributions of principal on
the notes or the certificates on a distribution date, as described under
"Description of the Transfer and Servicing Agreements" in this prospectus
supplement.

         The insurer will pay any Policy Claim Amount that is a Preference
Amount on the business day following receipt by the fiscal agent of the insurer
of:

          -    a certified copy of the order requiring the return of a
               preference payment;

          -    an opinion of counsel satisfactory to the insurer that the order
               is final and not subject to appeal;

          -    an assignment in such form as is reasonably required by the
               insurer, irrevocably assigning to the insurer all rights and
               claims of each Owner relating to or arising under the securities
               against the debtor which made the preference payment or otherwise
               with respect to the preference payment; and



                                      S-40

<PAGE>   121



          -    appropriate instruments, in form satisfactory to the insurer, to
               effect the appointment of the insurer as agent for the Owner in
               any legal proceeding related to the preference payment, provided
               that if they are received after 12:00 noon New York City time on
               a business day, they will be deemed to be received on the
               following business day.

Payments of the Policy Claim Amount will be disbursed to the receiver or the
trustee in bankruptcy named in the final order of the court exercising
jurisdiction on behalf of the Owner and not to any Owner directly unless the
Owner has returned principal or interest paid on the securities to the receiver
or trustee in bankruptcy, in which case the payment will be disbursed to the
Owner.

         The insurer will pay any other amount payable under the policy no later
than 12:00 noon New York City time on the later of:

          -    the distribution date on which the related Note Interest
               Distributable Amount, Certificate Interest Distributable Amount
               or outstanding principal amount in respect of a class of notes or
               of the certificates for which that distribution date is the final
               scheduled distribution date is due; or

          -    the second business day following receipt in New York, New York
               on a business day by the fiscal agent of a notice specifying the
               Policy Claim Amount which will be due and owing on the
               distribution date; provided, that if the notice is received after
               12:00 noon New York City time on that business day, it will be
               deemed to be received on the following business day.

If any notice received by the fiscal agent is not in proper form or is otherwise
insufficient for the purpose of making a claim under the policy it will be
deemed not to have been received by the fiscal agent, and the insurer or the
fiscal agent, as the case may be, will promptly so advise the indenture trustee
and the indenture trustee may submit an amended notice.

         Policy Claim Amounts due under the policy, unless otherwise stated
therein, will be disbursed by the fiscal agent to the indenture trustee on
behalf of the Owners by wire transfer of immediately available funds in the
amount of the Policy Claim Amount less, in respect of Policy Claim Amounts
including Preference Amounts, any amount held by the indenture trustee for the
payment of the Policy Claim Amount and legally available therefor.

         The fiscal agent is the agent of the insurer only and the fiscal agent
will in no event be liable to Owners for any acts of the fiscal agent or any
failure of the insurer to deposit or cause to be deposited sufficient funds to
make payments due under the policy.

         Subject to the terms of the indenture, the insurer shall be subrogated
to the rights of each Owner to receive payments under the securities to the
extent of any payment by the insurer under the policy.

                    nonappealable; or

          -    a court of competent jurisdiction, the New York Department of

                    possession of all or any material portion of the property of
                    the insurer.

         Each rating of the insurer should be evaluated independently. The
ratings reflect the respective rating agency's current assessment of the
creditworthiness of the insurer and its ability to pay claims on its policies of
insurance. Any further explanation of the significance of the above ratings may
be obtained only from the applicable rating agency.

         The above ratings are not recommendations to buy, sell or hold the
securities and the ratings may be subject to revision or withdrawal at any time
by the rating agencies. Any downward revision or withdrawal of any of the above
ratings may have an adverse effect on the market price of the securities. The
insurer does not guarantee the market price of the securities nor does it
guarantee that the ratings on the securities will not be revised or withdrawn.


                     CERTAIN FEDERAL INCOME TAX CONSEQUENCES

         In the opinion of Andrews & Kurth L.L.P. for federal income tax
purposes the notes will be characterized as debt, and the trust will not be
characterized as an association, or a publicly traded partnership, taxable as a
corporation. Each noteholder, by the acceptance of a note, will agree to treat
the notes as indebtedness, and each certificateholder, by the acceptance of a
certificate, will agree to treat the trust as a partnership in which the
certificateholders are partners for federal income tax purposes. Alternative
characterizations of the trust and the certificates are possible, but would not
result in materially adverse tax consequences to certificateholders. See
"Certain Federal Income Tax Consequences" in the prospectus for additional
information concerning the application of federal income tax laws to the trust
and the securities.

         Certificateholders who are tax-exempt entities or non-U.S. persons will
have tax consequences that may be considered adverse by those holders. See
"Certain Federal Income Tax Consequences - Trusts for Which a Partnership
Election is Made - Tax Consequences to Holders of the Certificates - Partnership
Taxation" and "- Tax Consequences to Foreign Certificateholders" in the
prospectus.


                              ERISA CONSIDERATIONS

THE NOTES

         Subject to the considerations set forth below and under "ERISA
Considerations" in the prospectus, the notes may be purchased by an employee
benefit plan or an individual retirement account subject to ERISA or Section
4975 of the tax code. A fiduciary of a benefit plan or IRA must determine that
the purchase of a note is consistent with its fiduciary duties under ERISA and
does not result in a nonexempt prohibited transaction as defined in Section 406
of ERISA or Section 4975 of the tax code. Section 406 of ERISA prohibits parties
in interest or disqualified persons with respect to a benefit plan or IRA from
engaging in certain transactions, including loans, involving a benefit plan or
IRA and its assets unless a statutory, regulatory or administrative exemption
applies to the transaction. Section 4975 of the tax code imposes certain


                                      S-45

<PAGE>   126


excise taxes or, in some cases, a civil penalty may be assessed under section
502(i) of ERISA, on parties in interest and disqualified persons which engage in
non-exempt prohibited transactions.

         The United States Department of Labor has issued a regulation (29 CFR
Section 2510.3-101) -- the "plan asset regulation" -- concerning the definition
of what constitutes the assets of a benefit plan or IRA. This regulation
provides that, as a general rule, the underlying assets and properties of
corporations, partnerships, trusts and certain other entities in which a benefit
plan or IRA purchases an "equity interest" will be deemed for purposes of ERISA
to be assets of the investing benefit plan or IRA unless certain exceptions
apply. The plan asset regulation defines an "equity interest" as any interest in
an entity other than an instrument that is treated as indebtedness under
applicable local law and which has no substantial equity features. Although the
issue is not free from doubt, the seller believes that the notes offered hereby
should not be treated as "equity interests" for purposes of the regulation.
Accordingly, the acquisition of the notes by Benefit Plan or IRA investors
should not cause the assets of the trust to be treated as "plan assets" for
purposes of Title I of ERISA. However, the notes may not be purchased with the
assets of a benefit plan or IRA if the seller, the servicer, the indenture
trustee, the owner trustee or any of their affiliates -

          -    has investment or administrative discretion with respect to the
               assets of the benefit plan or IRA;

          -    has authority or responsibility to give, or regularly gives,
               investment advice with respect to the assets of the benefit plan
               or IRA, for a fee and under an agreement or understanding that
               the advice (1) will serve as a primary basis for investment
               decisions with respect to the assets of the benefit plan or IRA
               and (2) will be based on the particular investment needs for the
               benefit plan or IRA; or

          -    is an employer maintaining or contributing to the benefit plan or
               IRA.

         Affiliates of the trust or the servicer might be considered or might
become parties in interest or disqualified persons with respect to a benefit
plan or IRA. In either case, the acquisition or holding of notes by or on behalf
of such a benefit plan or IRA could be considered to give rise to an indirect
prohibited transaction within the meaning of ERISA and the tax code, unless the
acquisition and holding of the notes is covered by one or more exemptions such
as Prohibited Transaction Class Exemption 84-14, which exempts certain
transactions effected on behalf of a benefit plan or IRA by a "qualified
professional asset manager", PTCE 90-1, which exempts certain transactions
involving insurance company pooled separate accounts, PTCE-91-38, which exempts
certain transactions involving bank collective investment funds, PTCE 95-60,
which exempts certain transactions involving insurance company general accounts,
or PTCE 96-23, which exempts certain transactions effected on behalf of a
benefit plan or IRA by certain "in-house asset managers". Each purchaser or
transferee of a note that is a benefit plan or IRA will be deemed to have
represented that the relevant conditions for exemptive relief under at least one
of the foregoing exemptions, or other applicable exemption providing
substantially similar relief, have been satisfied.

THE CERTIFICATES

         The seller believes that the certificates offered hereby should be
treated as "equity interests" for purposes of the plan asset regulation.
Accordingly, the certificates may not be acquired by -

          -    a benefit plan or IRA subject to ERISA or Section 4975 of the tax
               code; or

          -    any entity whose underlying assets include plan assets by reason
               of a benefit plan's or IRA's investment in the entity or which
               uses plan assets to acquire certificates.

         By its acceptance of a certificate, each certificateholder will be
deemed to have represented and warranted that it is not subject to the foregoing
limitation. In this regard, purchasers that are insurance companies should
consult with their counsel with respect to the United States Supreme Court case
interpreting the fiduciary responsibility rules of ERISA, John Hancock Mutual
Life Insurance Co. v. Harris Bank and Trust, decided December 12, 1993. In John
Hancock, the Supreme Court ruled that assets held in an insurance company's
general account may be deemed to be "plan assets" for ERISA purposes under
certain circumstances. Prospective purchasers should determine whether the
decision affects their ability to make purchases of the certificates. For
additional information regarding treatment of the certificates under ERISA, see
"ERISA Considerations" in the prospectus.

          -    the aggregate outstanding principal balance of the contracts on

fees. See "Certain Federal Income Tax Consequences" in the prospectus for
additional information concerning the application of federal income tax laws to
the trust and the certificates.

ERISA CONSIDERATIONS

Subject to the considerations discussed under "ERISA Considerations" in this
prospectus supplement and in the prospectus, the certificates are eligible for
purchase by employee benefit plans that are subject to ERISA. See "ERISA
Considerations" in this prospectus supplement and in the prospectus.

RATING

At the closing date, Standard & Poor's Ratings Services, a division of The
McGraw-Hill Companies, Inc., and Moody's Investors Service, Inc. will rate the
certificates in the highest rating category for the securities. The ratings of
the certificates will be based substantially on the issuance of the policy by
the insurer. See "Risk Factors - Rating" in this prospectus supplement.

REGISTRATION OF THE CERTIFICATES

Initially, the certificates will be in the form of one or more certificates
registered in the name of Cede & Co., as the nominee of DTC. If you acquire an
interest in the certificates through DTC, you will not be entitled to receive a
definitive security, except in the event that definitive securities are issued
in limited circumstances. See "Description of the Securities - Book-Entry
Registration" and "- Definitive Securities" in the prospectus.

                                  RISK FACTORS

         You should consider the following risk factors, as well as the other
factors described under the heading "Risk Factors" in the prospectus, before
deciding to purchase the certificates.

ONYX IS SUBJECT TO ALL OF THE RISKS INHERENT IN A RELATIVELY NEW BUSINESS
ENTERPRISE BECAUSE OF ITS LIMITED OPERATING HISTORY.

         Onyx began its operations in February 1994 as a purchaser and servicer
of motor vehicle retail installment sales contracts. Accordingly, Onyx has
performance data for only a relatively short period with respect to the
contracts it purchases and originates. As the portfolio of contracts purchased
and originated by Onyx and its subsidiaries matures, delinquency percentages and
loan losses may increase.

         As Onyx expands its operations in the United States, it 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.

         Onyx experienced operating losses from its inception through December
31, 1995. Onyx's operating losses and net income for the years ended December
31, 1994 through December 31, 1998, and for the ___ months ended ________, are
set forth below:

THE ABSENCE OF A SECONDARY MARKET COULD LIMIT YOUR ABILITY TO RESELL YOUR
CERTIFICATES.

         The absence of a secondary market for the certificates could limit your
ability to resell them. This means that if in the future you want to sell any of
your certificates before they mature, you may be unable to find a buyer or, if
you find a buyer, the selling price may be less than it would have been if a
market existed for the certificates. There is currently no secondary market for
the certificates. The underwriters currently intend to participate in making a
secondary market in the certificates, but they are not under any obligation to
do so. We cannot assure you that a secondary market for the certificates will
develop. If a secondary market does develop, we cannot assure you that it will
continue or that you will be able to resell your certificates.

PREPAYMENTS ON CONTRACTS WILL CAUSE PREPAYMENTS ON YOUR SECURITIES RESULTING IN
REINVESTMENT RISK TO YOU.

         You may receive payment of principal on your certificates earlier than
you expect for the reasons set forth below. You may not be able to reinvest any
principal paid to you earlier than you expected at a rate of return that is
equal to or greater than the rate of return on your certificates.

         Prepayments on the contracts by the related obligors and purchases of
the contracts by the seller and the servicer will shorten the life of the
certificates to an extent that cannot be fully predicted. The contracts included
in the trust may be prepaid, in full or in part, voluntarily or as a result of
defaults, theft of or damage to the related vehicles or other reasons. Onyx will
be required to repurchase a contract from the seller, and the seller will be
required to repurchase a contract from the trust, if Onyx breached its
representations and warranties with respect to the contract in the pooling and
servicing agreement with the seller. Onyx, in its capacity as servicer, will
also be required to purchase a contract from the trust if it breaches its
servicing obligations with respect to the contract and the contract is
materially and adversely affected by the breach. The purchase will also be
entitled to purchase all of the remaining contracts from the trust once the
aggregate principal balance of the contracts is 10% or less than the aggregate
principal balance of the contracts as of their applicable cut-off date.

         The rate of distributions of principal on the certificates depends
primarily on the rate of payments, including prepayments, on the principal
balance of the contracts. As a result, final distribution on the certificates
could occur significantly earlier than the final distribution date.

         Onyx cannot predict the actual prepayment rates that will occur on the
contracts in either stable or changing interest rate environments. See "-
Limited Operating History of Onyx". Moreover, many other factors will affect the
amount and timing of distributions of principal on the certificates. The factors
include:

          -    the level of delinquencies, defaults and losses on the contracts;
               and

          -    the payment of any accelerated amounts on the certificates
               following an event of default under the pooling and servicing
               agreement.

         You will bear all the reinvestment risks relating to prepayments on the
contracts and resulting from distributions of principal on the certificates.
These reinvestment risks include the possibility that you may not be able to
reinvest the distributions of principal in alternative comparable investments
having similar yields. See "Maturity and Prepayment Considerations" in this
prospectus supplement and in the prospectus.

<PAGE>   148
GEOGRAPHIC CONCENTRATION MAY ADVERSELY AFFECT THE PERFORMANCE OF THE CONTRACTS.

         Economic conditions in the states where the obligors under the
contracts live and work may affect the delinquency, loan loss and repossession
experience of the trust with respect to the contracts. Initial contracts
representing approximately___% of the initial contracts as of __________, 2000
were originated in California. As of ____________, 2000, the aggregate principal
balances of initial contracts originated in any single state other than
California did not exceed ______% of the aggregate principal balance of the
initial contracts on that date. The geographic concentration of all of the
contracts as of the closing date, including both the initial contracts and the
additional contracts purchased by the trust, will be substantially similar to
that of the initial contracts. Adverse economic conditions or other factors
particularly affecting California or other states in which the contracts are
geographically concentrated might adversely affect the performance of the
contracts. See "The Contracts - Geographic Concentration of the Initial
Contracts" in this prospectus supplement.

YOU MAY SUFFER LOSSES DUE TO THE LIMITED ASSETS OF THE TRUST.

         You may suffer a loss on your securities if the assets of the trust are
insufficient to pay fully the principal amount of the certificates. The trust
does not have, nor is it permitted or expected to have, any significant assets
or sources of funds other than the contracts. You must rely upon payments on the
contracts and payments of claims made under the policy for repayment of the
certificates.

         The policy will guarantee interest distributions and principal
distributions on each distribution date. However, if the insurer defaults in its
obligations under the policy, the trust will have to depend solely on
collections on the contracts to make distributions then due on the certificates.
See "Description of the Insurer" and "The Certificates and the Agreement - The
Financial Guarantee Insurance Policy" in this prospectus supplement.

DOWNGRADING OF THE RATING OF THE [INSURER] OR THE CERTIFICATE MAY HAVE AN
ADVERSE AFFECT ON THE LIQUIDITY AND MARKET VALUE OF THE CERTIFICATES.

         On the closing date, the certificates will be rated "AAA" by Standard &
Poor's and "Aaa" by Moody's. 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. Any rating agency rating the certificates may lower or
withdraw its rating if, in the sole judgment of the rating agency, circumstances
in the future so warrant. For example, the downgrading of the rating of the
[insurer] may affect the ratings on the certificates. We cannot predict with
certainty what effect any revision or withdrawal of a rating of the certificates
may have on the liquidity or market value of the certificates. The ratings of
the certificates address the likelihood of timely payment of scheduled interest
distributions and principal distributions, which are guaranteed by the [insurer]
under the policy. The ratings of the certificates are substantially based on the
issuance of the policy by the [insurer], and are dependent on the rating of the
[insurer]. See "Description of the Insurer" in this prospectus supplement for a
description of the [insurer's] rating.

IF PROBLEMS ASSOCIATED WITH THE YEAR 2000 PROBLEM WERE TO OCCUR, YOU COULD
EXPERIENCE DELAYS OR SHORTFALLS IN PAYMENTS DUE ON THE SECURITIES.

         Historically, many information technology systems were developed to
recognize the year as a two-digit number, with the digits "00" being recognized
as the year 1900. The year 2000 presents a number of potential problems for
these systems, including potentially significant processing errors or failures.

         Onyx has developed and executed a comprehensive plan designed to
address the "year 2000" problem for its in-house and third party information
technology applications. Onyx completed its year 2000 testing in 1999 and has
experienced no problems to date related to the year 2000 problem.. However,
there can be no assurance that all potential year 2000 problems have been
identified and corrected. Accordingly, you could be adversely affected if the
information technology systems of Onyx are not fully year 2000 compliant and
that non-compliance disrupts the collection or distribution of collections on
the contracts.

         With respect to the year 2000 problem, DTC has informed members of the
financial community that it has developed and is implementing a program so that
its systems, as they relate to timely payment of distributions, including
principal and interest payments, to holders of securities, book-entry
deliveries, and settlement of trades within DTC, continue to function
appropriately on and after January 1, 2000. This program includes a technical
assessment and a remediation plan, each of which is complete. Additionally,
DTC's plan includes a testing phase, which is expected to be completed within
appropriate time frames.

         However, DTC's ability to perform properly its services is also
dependent upon other parties, including but not limited to its participating
organizations, through which you will hold your certificates, as well as
computer systems of third party service providers. DTC has informed the
financial community that it is contacting and will continue to contact third
party vendors from whom DTC acquires services to impress upon them the
importance of those services being year 2000 compliant and to determine the
extent of their efforts for year 2000 remediation, and, as appropriate, testing,
of their services.

         In addition, DTC has stated that it is in the process of developing
those contingency plans as it deems appropriate. If problems associated with the
year 2000 problem were to occur with respect to DTC and the services described
above, you could experience delays or shortfalls in payments due on the
certificates.


                                    THE TRUST

         The seller will establish the Onyx Acceptance Grantor Trust 2000-___
under the pooling and servicing agreement by selling and assigning to
[____________], in its capacity as trustee of the trust, the property described
under the heading "The Trusts" in the prospectus. In exchange for the trust
property, the trustee will execute and authenticate the certificates. Each
certificate will represent a fractional undivided interest in the trust.


                                       S-8
<PAGE>   150
         The trust will be formed for this transaction under the pooling and
servicing 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 on the certificates; and

          -    as otherwise described in this prospectus supplement and as
               provided in the pooling and servicing agreement.

The trust will not acquire any motor vehicle contracts or assets other than the
trust property described in the prospectus and will not have any need for
additional capital resources.


                  THE ONYX PORTFOLIO OF MOTOR VEHICLE CONTRACTS

PURCHASE, ORIGINATION AND SERVICING OF MOTOR VEHICLE CONTRACTS

         Onyx's purchase and origination of motor vehicle contracts are
described under the heading "The Onyx Portfolio of Motor Vehicle Contracts -
Purchase and Origination of Motor Vehicle Contracts" in the prospectus. At
______, 200__, Onyx had agreements with approximately ___ dealers, of which
approximately ___% are franchised new car dealerships and approximately ___% are
independent used car dealerships. All of the contracts will have been sold to
the seller and then to the trust.

         Onyx, together with its subsidiaries, had acquired or originated motor
vehicle contracts totaling approximately $___ billion from commencement of
operations through _________. As of _________, Onyx had amassed a servicing
portfolio of approximately $___ billion. As of _______, approximately ____% of
Onyx's servicing portfolio consisted of retail installment sale contracts and
installment loan agreements secured by used motor vehicles, and ___% secured by
new motor vehicles. As of ________, Onyx had total assets of approximately $____
million and stockholder's equity of $___ million.

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 an annual
basis commencing December 31, 1996. 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 purchased or originated by a subsidiary of
Onyx, in accordance with credit underwriting criteria established by Onyx. In
February 1994, Onyx


                                       S-9
<PAGE>   151
commenced its operations as a purchaser and servicer of motor vehicle retail
installment sales contracts. Accordingly, Onyx has historical performance for
only a limited time period with respect to the motor vehicle contracts it
purchases and originates and, consequently, 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" in this prospectus supplement and
in the prospectus.

         With the continued expansion of Onyx in the eastern United States and
the significant growth in Onyx's existing branches, Onyx has centralized and
improved its servicing and collection process. Onyx believes that a centralized
group is efficient and effective, and assures that collection practices and
policies are applied consistently throughout the company. Management continues
to rely on the use of current technology such as predictive dialers utilizing an
automated processing system for contacting delinquent borrowers. Onyx also has a
payment system that allows electronic payment on delinquent accounts to be
applied the same day as payment is sent or initiated by the borrower.

                                  THE CONTRACTS

         All of the contracts will have been purchased by the seller from Onyx.
Substantially all of the contracts have been purchased by Onyx from new and used
car dealers unaffiliated with Onyx or the seller, and a limited number of
contracts will have been purchased or originated by subsidiaries of Onyx. See
"The Onyx Portfolio of Motor Vehicle Contracts" in this prospectus supplement
and in the prospectus. Each of the contracts in the trust will be a fixed rate
contract where the allocation of each payment between interest and principal is
calculated using the rule of 78's method, actuarial method or the simple
interest method. Each of these methods is explained under the heading "The Onyx
Portfolio of Motor Vehicle Contracts - Allocation of Payments on Contracts to
Interest and Principal" in the prospectus. Initial contracts representing
approximately _______% of the Aggregate Scheduled Balance allocate interest and
principal in accordance with the rule of 78's or the actuarial method, and
initial contracts representing approximately ______% of the Aggregate Scheduled
Balance allocate interest in accordance with the simple interest method.

         The contracts will have been selected from the motor vehicle contracts
in the portfolio of Onyx using the following criteria. No selection procedures
will have been used with respect to the contracts that are believed by Onyx or
the seller to be adverse to the securityholders or [insurer]. Initial contracts
representing approximately ______% of the Aggregate Scheduled Balance are
secured by new vehicles, and initial contracts representing approximately
______% of the Aggregate Scheduled Balance are secured by used vehicles. The
seller may not substitute other motor vehicle contracts for the contracts at any
time during the term of the sale and servicing agreement.

         The seller will represent that each contract included in the trust
satisfies the following eligibility requirements:

          -    the contract is secured by a new or used automobile, light-duty
               truck or van;

               not more than ___ months;

          -    the contract has an original maturity of not more than ___
               months;

          -    the contract is a fully-amortizing fixed rate contract which
               provides for level scheduled monthly payments determined on the
               basis of the rule of 78's, actuarial or the simple interest
               method, except for the last payment, which may be minimally
               different from the level payments;

          -    the contract is secured by a vehicle that as of the Cut-Off Date
               has not been repossessed without reinstatement;

          -    the contract has no payment more than ___ days past due as of the
               Cut-Off Date;

          -    the contract has a remaining principal balance as of the Cut-Off
               Date of at least $___________; and

          -    as of the Cut-Off Date, the seller has not received notice that
               the related obligor has filed for bankruptcy.

         Set forth below is data concerning the initial contracts as of the
Initial Cut-Off Date which had an Aggregate Scheduled Balance of $___________.
Data concerning all of the contracts (both the initial contracts and the
Subsequent Contracts) will be available to purchasers of the securities at or
before the initial delivery of the securities and will be filed with the SEC on
Form 8-K within 15 days after the initial delivery of the securities. While the
financial and other data for the Subsequent Contracts will differ somewhat from
the data for the initial contracts, the characteristics of the contracts as a
whole will not vary materially from the characteristics of the initial contracts
described below.

<PAGE>   156
                     MATURITY AND PREPAYMENT CONSIDERATIONS

         The contracts are or will be prepayable in full by the obligors at any
time without penalty. See "Maturity and Prepayment Considerations" in the
prospectus regarding the effects of prepayments on the weighted average life of
the contracts. As the rate of distribution of principal of the certificates
depends primarily on the rate of payment, including prepayments, of the
principal of the contracts, final distribution of the certificates is expected
to occur earlier, and could occur significantly earlier, than the Final
distribution date for the certificates.

         Onyx can make no prediction as to the actual prepayment rates that will
be experienced on the contracts in either stable or changing interest rate
environments. In addition, the rate of distributions of principal of the
certificates will be affected by the incidence of delinquencies, defaults and
losses and by any accelerated payments made on the certificates following an
event of default under the pooling and servicing agreement. See "Risk Factors -
Maturity and Prepayment Considerations" in this prospectus supplement.


                              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 Pool
Balance as of the end of the Collection Period preceding the related Collection
Period, or the Aggregate Scheduled Balance of the contracts as of the applicable
Cut-Off Date, 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" in this prospectus supplement.

         Although the contracts have different APRs, the yield on each
individual contract, using the recomputed yield for rule of 78's contracts, will
equal or exceed ____%. Therefore, disproportionate rates of prepayments between
contracts with higher and lower APRs will not affect the yield to
certificateholders.


                                 USE OF PROCEEDS

         The net proceeds of the initial sale of certificates will be used by
the trust to purchase the contracts from the seller under the pooling and
servicing agreement and to fund the deposits in the collateral accounts
maintained for the benefit of the certificateholders and the insurer. The net
proceeds to be received by the seller from the sale of the contracts to the
trust will be used by the seller to repay indebtedness incurred, or to pay other
amounts owed, in connection with its acquisition of the contracts and to pay
other expenses in connection with the pooling of the contracts and the issuance
of the certificates.

<PAGE>   157
                       THE CERTIFICATES AND THE AGREEMENT


         The certificates will be issued under the pooling and servicing
agreement, a form of which will be filed with the SEC following the issuance of
the certificates. The following summaries of the pooling and servicing
agreement, together with the information set forth in the prospectus, describe
the material terms of the pooling and servicing agreement. However, these
summaries do not purport to be complete and are subject to, and qualified in
their entirety by reference to, the provisions of the pooling and servicing
agreement. Where particular provisions of or terms used in the pooling and
servicing agreement are referred to, the actual provisions, including
definitions of terms, are incorporated by reference as part of those summaries.


INITIAL CERTIFICATE BALANCE

         The initial principal balance of the certificates is approximately
equal to $_________________, the aggregate principal balance of the contracts as
of the Cut-Off Date calculated in accordance with the rule of 78's method, the
actuarial method or the simple interest method. Each of these methods is
explained under the heading "The Onyx Portfolio of Motor Vehicle Contracts -
Allocation of Payments on Contracts to Interest and Principal" in the
prospectus. See "The Contracts" in this prospectus supplement and in the
prospectus.

DISTRIBUTIONS OF PRINCIPAL AND INTEREST

         On each distribution date, monthly interest in an amount equal to the
product of one-twelfth of the pass-through rate and the Pool Balance as of the
end of the Collection Period preceding the related Collection Period will be
distributed on a pro rata basis to the certificateholders of record as of the
related record date; provided that the interest distribution with respect to the
first distribution date will include an additional $____ per $1,000 of initial
principal balance of the certificates. Interest will be paid to the extent of
the portion of the Pool Balance represented by contracts, from collections
received on the contracts on deposit in the collection account or previously
collected and available for distribution. Each interest distribution will be
calculated on the basis of a 360-day year consisting of twelve 30-day months.

         Unless and until definitive certificates have been issued,
distributions on each distribution date will be made through the facilities of
DTC and the related record date will be the business day prior to that
distribution date. If definitive certificates are issued, the related record
date will be the last day of the calendar month preceding that distribution
date. The final distribution of principal of and interest on each certificate
will be made only upon presentation and surrender of the certificate on or after
the final scheduled distribution date, or any earlier termination date as is
provided by the pooling and servicing agreement, at the office or agency of the
trustee maintained for that purpose.

         On each distribution date, the Principal Distribution for the related
Collection Period will be passed through to the certificateholders.

         The amount of the monthly installments of principal and interest for a
contract due on each due date under that contracts is substantially equal for
the term of the contract. The


                                      S-16
<PAGE>   158
Scheduled Balance of each 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 pooling and servicing agreement.

         At the issuance of the certificates, the initial aggregate principal
amount of the certificates will be approximately equal to the sum of the
Aggregate Scheduled Balance of all the contracts as of the Cut-Off Date.

OPTIONAL REDEMPTION

         In order to avoid excessive administrative expense, the servicer is
permitted at its option to purchase the remaining contracts from the trust on
any distribution date as of which the Pool Balance, after giving effect to the
Principal Distribution otherwise to be made on that distribution date, has
declined to 10% or less of the Aggregate Scheduled Balance of the contracts as
of the applicable Cut-Off Date. This purchase may be made by the servicer at a
price equal to the Aggregate Scheduled Balance of the contracts on the date of
repurchase 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 payment to any
certificateholder will be made only upon surrender and cancellation of the
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 measures to locate a certificateholder and those measures have
failed, will be distributed to a charity designated by the servicer.

THE FINANCIAL GUARANTEE INSURANCE POLICY

         If on the fifth business day prior to any distribution date the amount
on deposit in the collection account after giving effect to all amounts
deposited to or payable from the payahead account with respect to the
distribution date, is less than the sum of the servicing fee, Principal
Distribution, and Interest Distribution for that distribution date, then the
trustee, by delivering a notice in accordance with the policy, will demand
payment under the policy in an amount equal to the deficiency. The insurer will
pay or cause to be paid the deficiency amount to the trustee for credit to the
collection account. The trustee will withdraw from the collection account and
will pay the deficiency amount to the certificateholders on the related
distribution date.

         If on the business day preceding the final scheduled distribution date,
any principal amount of certificates is still outstanding, then the trustee will
demand payment on the policy 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 scheduled distribution date. The
insurer will pay or cause to be paid the deficiency amount to the trustee under
the trustee's instructions for credit to the collection account and on the final
scheduled distribution date, the trustee will withdraw from the collection
account and shall pay that amount to the certificateholders.

<PAGE>   159
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
contracts and the proceeds thereof, including its security interests in the
financed vehicles. Each contract will be identified in a schedule appearing as
an exhibit to the pooling and servicing agreement. The trustee will,
concurrently with this sale and assignment, execute, authenticate and deliver
the certificates to [underwriters] against payment to the seller of the net
purchase price of the sale of the certificates. Prior to sale of the contracts
to the trustee and the issuance of the certificates, Onyx and each of its
participating subsidiaries will sell and assign to the seller their entire
interest in the contracts. See "Description of the Transfer and Servicing
Agreements - Sale and Assignment of the Contracts" in the prospectus.

DISTRIBUTIONS

         Subject to the last sentence of this paragraph, distributions on the
certificates generally will be made on each distribution date by the paying
agent out of net collections on the contracts, exclusive of amounts representing
payments due in the collection period in which the distribution date occurs and
any future Collection Periods, for the Collection Period preceding the
distribution date, plus amounts payable from the payahead account. This amount
will be applied -

         -        first, to the servicer in payment of the servicing fee;

         -        second, to payment of the interest distribution and the
                  Principal Distribution to the certificateholders on that
                  distribution date in accordance with the pooling and servicing
                  agreement;

         -        third, to the insurer, the premium for the policy; and

         -        fourth, any balance will 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 policy, to satisfy obligations
                  owing to the insurer or to reserve against the possibility of
                  future draws, amounts remaining will be released to the
                  beneficiaries of the spread account trust.

Any amounts distributed under clause fourth above will not be available to make
distributions to the certificate-holders on the current or any future
distribution date. Under the policy, 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 and
amounts payable from the payahead account, is less than the sum of the servicing
fee, the interest distribution and the Principal Distribution due to the
certificateholders for that Distribution Date. In addition, on the final
scheduled distribution date, to the extent the amount on deposit and available
in the collection account, including amounts payable from the payahead account,
is less


                                      S-18
<PAGE>   160
than all remaining unpaid interest and principal on the certificates, the
insurer is obligated to pay under the policy or cause to be paid the amount of
the shortfall. In addition, on the final scheduled distribution date, to the
extent the amount on deposit and available in the collection account, including
from the payahead account, is less than all remaining unpaid interest and
principal on the certificates, the insurer is obligated to pay under the policy
or cause to be paid the amount of the shortfall. See "- Distributions of
Principal and Interest" in this prospectus supplement.

SERVICING FEE

         The servicer will be entitled to compensation for the performance of
its obligations under the pooling and servicing agreement. The servicer will be
entitled to receive on each distribution date an amount equal to the product of
one-twelfth of ____% per annum multiplied by the Pool Balance as of the end of
the Collection Period preceding the related Collection Period. As additional
compensation, the servicer or its designee will 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 of a rule of 78's or actuarial
contract that is subject to a Full Prepayment exceeds the Scheduled Balance of
the contract. The servicer will pay all expenses incurred by it in connection
with its servicing activities under the pooling and servicing agreement and will
not be entitled to reimbursement of those expenses except to the extent they
constitute Liquidation Expenses or expenses recoverable under an applicable
insurance policy.

WAIVERS AND EXTENSIONS

         The pooling and servicing agreement requires the servicer to use its
best efforts to collect all payments called for under the terms and provisions
of the contracts. The servicer, consistent with the foregoing, will be
permitted, in its discretion, to waive changes and grant extensions as described
under "Description of the Transfer and Servicing Agreements - Waivers and
Extensions" in the prospectus. The maturity date of a contract, however, may not
be extended more than ____ days past the originally scheduled maturity date, and
in no event beyond the final scheduled distribution date.

STATEMENTS TO CERTIFICATEHOLDERS

         On each distribution date, the trustee will include with each
distribution to each certificateholder a statement setting forth for that
distribution date the information described under "Description of the Securities
- - Statements to Securityholders" in the prospectus.

CERTAIN MATTERS RELATING TO THE INSURER

         Notwithstanding any provision in the prospectus to the contrary, in the
event an insurer default shall have occurred and be continuing, the insurer will
not have the right to take any action under the pooling and servicing agreement,
to terminate the servicer, or to control or direct


                                      S-19
<PAGE>   161
the actions of the seller, the servicer or the trustee under the terms of the
pooling and servicing agreement. In this event, the consent of the insurer will
not be required with respect to any action, or waiver of a right to take action,
to be taken by the seller, the servicer, the trustee or the certificateholders;
provided, that the consent of the insurer will be required at all times with
respect to any amendment of the pooling and servicing agreement.

of the insurer is _________________.

         The insurer does not accept any responsibility for the accuracy or
completeness of this prospectus supplement or any information or disclosure
contained in this prospectus supplement, or omitted herefrom, other than with
respect to the accuracy of the information regarding the insurer set forth under
the heading "Description of the Insurer". Additionally, the insurer makes no
representation regarding the certificates or the advisability of investing in

         THE POLICY IS NOT COVERED BY THE PROPERTY/CASUALTY INSURANCE SECURITY
FUND SPECIFIED IN ARTICLE 76 OF THE NEW YORK INSURANCE LAW.

         Moody's Investors Service, Inc. rates the financial strength of the
insurer "Aaa".

         Standard & Poor's Ratings Services, a division of The McGraw-Hill
Companies, Inc., rates the financial strength of the insurer "AAA".

         Fitch IBCA, Inc., formerly known as Fitch Investors Service, L.P.,
rates the financial strength of the insurer "AAA".

         Each rating of the insurer should be evaluated independently. The
ratings reflect the respective rating agency's current assessment of the
creditworthiness of the Insurer and its ability


                                      S-21
<PAGE>   163
to pay claims on its policies of insurance. Any further explanation of the
significance of the above ratings may be obtained only from the applicable
rating agency.

         The above ratings are not recommendations to buy, sell or hold the
certificates and the ratings may be subject to revision or withdrawal at any
time by the rating agencies. Any downward revision or withdrawal of any of the
above ratings may have an adverse effect on the market price of the
certificates. The insurer does not guarantee the market price of the
certificates nor does it guarantee that the ratings on the certificates will not
be revised or withdrawn.


                              ERISA CONSIDERATIONS

         Subject to the considerations set forth below and under "ERISA
Considerations" in the prospectus, the certificates may be purchased by an
employee benefit plan or an individual retirement account subject to ERISA or
Section 4975 of the tax code. A fiduciary of a benefit plan or IRA must
determine that the purchase of a certificate is consistent with its fiduciary
duties under ERISA and does not result in a nonexempt prohibited transaction as
defined in Section 406 of ERISA or Section 4975 of the tax code.

         The DOL has granted to [underwriter] an administrative exemption from
certain of the prohibited transaction rules of ERISA with respect to the initial
purchase, the holding and the subsequent resale by benefit plans and IRA's of
certificates representing interests in asset backed pass-through trusts that
consist of receivables, loans and other obligations that meet the conditions and
requirements of the exemption. On July 21, 1997, the DOL adopted an Amendment to
Prohibited Transaction Exemptions that modified the exemption with respect to
transactions that utilize prefunding. The receivables covered by the exemption
include motor vehicle installment obligations such as the contracts.

         Among the conditions that must be satisfied for the exemption to apply
to the acquisition by a benefit plan or IRA of the certificates are the
following:

         -        the acquisition of the certificates by a benefit plan or IRA
                  is on terms, including the price for the certificates, that
                  are at least as favorable to the benefit plan or IRA as they
                  would be in an arm's-length transaction with an unrelated
                  party;

         -        the rights and interests evidenced by the certificates
                  acquired by the benefit plan or IRA are not subordinated to
                  the rights and interests evidenced by other certificates of
                  the trust;

         -        the Certificates acquired by the benefit plan or IRA have
                  received a rating at the time of the acquisition that is in
                  one of the three highest generic rating categories from
                  Standard & Poor's, Moody's, Duff & Phelps Inc. or Fitch
                  Investors Service, Inc.;



                                      S-22
<PAGE>   164
         -        the trustee is not an affiliate of any member of the
                  Restricted Group;

         -        the sum of all payments made to the underwriters in connection
                  with the distribution of the certificates represents not more
                  than reasonable compensation for underwriting the
                  certificates;

         -        the sum of all payments made to and retained by the seller
                  pursuant to the sale of the contracts to the trust represents
                  not more than the fair market value of the contracts;

         -        the sum of all payments made to and retained by the servicer
                  represents not more than reasonable compensation for the
                  servicer's services under the pooling and servicing agreement
                  and reimbursement of the servicer's reasonable expenses in
                  connection therewith;

         -        the benefit plan or IRA investing in the certificates is an
                  "accredited investor" as defined in Rule 501(a)(1) of
                  Regulation D under the Securities Act of 1933, as amended;

         -        the principal amount of obligations added to the trust after
                  the closing date does not exceed 25% of the principal balance
                  of the certificates being offered as of the closing date;

         -        all additional obligations meet the same terms and conditions
                  for eligibility as the obligations originally included in the
                  trust, which terms and conditions have been approved by one of
                  the above-named rating agencies, except that the terms and
                  conditions may be modified with the prior approval of a rating
                  agency or of a majority of the holders of the certificates
                  offered;

         -        the addition of the obligations during the funding period does
                  not result in a ratings downgrade;

         -        the weighted average annual percentage rate of all obligations
                  in the trust at the end of the funding period is not more than
                  100 basis points lower than the weighted average as of the
                  closing date;

         -        the characteristics of the additional obligations are
                  monitored by a third party credit enhancer or certificate
                  insurer which is independent of the sponsor of the trust, or
                  an independent accountant delivers a letter, with copies to
                  the relevant rating agencies, underwriters and trustee,
                  stating that the characteristics of the additional obligations
                  conform to the characteristics with respect thereto specified
                  in the offering documents;

         -        the funding period ends no later than 90 days after the
                  closing date;


                                      S-23
<PAGE>   165
         -        amounts on deposit in a prefunding account and/or related
                  capitalized interest account are invested only in investments
                  permitted by the relevant rating agencies that are direct
                  obligations of or fully guaranteed by the United States or any
                  agency or instrumentality thereof or rated, or issued by an
                  issuer rated, in one of the three highest generic rating
                  categories by the relevant rating agencies.

         The trust must also meet the following requirements:

         -        the corpus of the trust must consist solely of assets of the
                  type that have been included in other investment pools;

         -        certificates in the other investment pools must have been
                  rated in one of the three highest rating categories of
                  Standard & Poor's, Moody's, Duff & Phelps Inc. or Fitch
                  Investors Service, Inc. for at least one year prior to the
                  benefit plan's or IRA's acquisition of certificates;

         -        certificates evidencing interests in the other investment
                  pools must have been purchased by investors other than benefit
                  plans or IRA's for at least one year prior to any benefit
                  plan's or IRA's acquisition of certificates;

The exemption provides relief from certain self-dealing/conflict of interest
prohibited transactions that may occur when the benefit plan or IRA fiduciary
causes a benefit plan or IRA to acquire certificates in a trust in which the
fiduciary, or his affiliate, is an obligor on the receivables held in the trust
provided that, among other requirements:

         -        in the case of an acquisition in connection with the initial
                  issuance of certificates, at least 50% of each class of
                  certificates in which benefit plans or IRA's have invested is
                  acquired by persons independent of the Restricted Group and at
                  least 50% of the aggregate interest in the trust is acquired
                  by persons independent of the Restricted Group;

         -        the fiduciary, or its affiliate, is an obligor with respect to
                  5% or less of the fair market value of the obligations
                  contained in the trust;

         -        the benefit plan's or IRA's investment in certificates does
                  not exceed 25% of all of the certificates outstanding at the
                  time of the acquisition; and

         -        immediately after the acquisition, no more than 25% of the
                  assets of the benefit plan or IRA are invested in certificates
                  representing an interest in one or more trusts containing
                  assets sold or serviced by the same entity.

The exemption does not apply to benefit plans or IRA's sponsored by any member
of the Restricted Group.



                                      S-24
<PAGE>   166
         The seller believes that the exemption will apply to the acquisition,
holding and resale of the certificates by a benefit plan or IRA and that all
conditions of the exemption other than those within the control of investors
will be met. However, there can be no assurance that the DOL or the IRS will not
take a contrary position, nor that the position will be sustained. One or more
alternative exemptions may be available with respect to certain prohibited
transactions to which the exemption is not applicable, depending in part upon
the type of benefit plan's or IRA's fiduciary making the decision to acquire the
certificates and the circumstances under which the decision is made, including,
but not limited to:

         -        Prohibited Transactions Class Exemption 91-38, regarding
                  investments by bank collective investment funds; or

         -        PTCE 90-1, regarding investments by insurance company pooled
                  separate accounts.

Before purchasing the certificates, a benefit plan's or IRA's fiduciary should
consult with its counsel to determine whether the conditions of the exemption or
any other exemption would be met. A purchaser of the certificates should be
aware, however, that even if the conditions specified in one or more exemptions
are met, the scope of the relief provided by the applicable exemption or
exemptions might not cover all acts that might be construed as prohibited
transactions.

         As described above, the acquisition of a certificate by a benefit plan
or IRA could result in various unfavorable consequences for the benefit plan or
IRA or its fiduciaries under the regulations unless one of the exceptions in the
regulations or an exemption is available. See "ERISA Considerations" in the
prospectus.

         Prospective benefit plan and IRA investors should consult with their
legal advisors concerning the impact of ERISA and the tax code, the
applicability of the exemption or any other exemptions, and the potential
consequences of any purchase in their specific circumstances, prior to making an
investment in a certificate. Any benefit plan or IRA which acquires a beneficial
ownership interest in certificates will be deemed, by virtue of the acceptance
and acquisition of the ownership interest, to have represented to the seller and
the trustee that the benefit plan or IRA is an "accredited investor" for
purposes of Rule 501(a)(1) of Regulation D under the Securities Act.

         A governmental plan as defined in Section 3(32) of ERISA is not subject
to ERISA or Section 4975 of the tax code. However, such a governmental plan may
be subject to federal, state or local law which is to a material extent similar
to the provisions of ERISA or Section 4975 of the tax code. A fiduciary of a
governmental plan should make its own determination as to the need for and
availability of any exemptive relief under such laws.

</TABLE>

         The seller has been advised by the underwriters that they propose
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 that
price less a concession not in excess of ____% of the principal amount thereof.
The underwriters may allow, and the 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 the concession and discount may be changed. The
underwriters are obligated to purchase and pay for all of the certificates if
any certificates are purchased. The underwriters currently intend, but are not
obligated, to make a market in the certificates.

         During and after the offering, the underwriters may purchase and sell
the certificates in the open market in transactions in the United States. These
transactions may include overallotment and stabilizing transactions and
purchases to cover short positions created in connection with the offering. The
underwriters also may impose a penalty bid, whereby selling concessions allowed
to broker-dealers in respect of the certificates sold in the offering for their
account may by reclaimed by the underwriters if the certificates are repurchased
by the underwriters in stabilizing or covering transactions. These activities
may stabilize, maintain or otherwise affect the market price of the
certificates, which may be higher than the price that might otherwise prevail in
the open market. These transactions may be effected in the over-the-counter
market or otherwise, and these activities, if commenced, may be discontinued at
any time.

         The seller and Onyx have agreed to indemnify the underwriters against
certain liabilities, including liabilities under applicable securities laws, or
contribute to payments the underwriters may be required to make in respect
thereof.

ITEM 15. 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") 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 or officer 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")
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 or officer to repay such
advances if it is ultimately determined that the director or officer 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 has acquired 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


                                      II-1
<PAGE>   173

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 has entered 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 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 Underwriter, for certain liabilities rising under the Securities Act or
otherwise. It also provides, in certain limited instances, for indemnification
by the Underwriter of the Company with respect to information furnished by or on
behalf of the Underwriter that is contained in this prospectus or included as
part of this Registration Statement.

ITEM 17. UNDERTAKINGS

        (a) The undersigned registrant hereby undertakes:

                (1) To file, during any period in which offers or sales are
        being made of the securities registered hereby, a post-effective
        amendment to this registration statement:

                        (i) to include any prospectus required by Section
                10(a)(3) of the Securities Act of 1933;

                        (ii) to reflect in the prospectus any facts or events
                arising after the effective date of this registration statement
                (or the most recent post-effective amendment hereof) which,
                individually or in the aggregate, represent a fundamental change
                in the information set forth in this registration statement; and

                        (iii) to include any material information with respect
                to the plan of distribution not previously disclosed in this
                registration statement or any material change to such
                information in this registration statement.

        Provided, however, that the undertakings set forth in clauses (i) and
        (ii) above do not apply if the information required to be included in a
        post-effective amendment by those clauses is contained in periodic
        reports filed with or furnished to the Commission by the registrant
        pursuant to Section 13 or Section 15(d) of the Securities Exchange Act
        of 1934 that are incorporated by reference in this registration
        statement.

<PAGE>   175

                (2) That, for the purpose of determining any liability under the
        Securities Act of 1933, each such post-effective amendment 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.

                (3) To remove from registration by means of a post-effective
        amendment any of the securities being registered which remain unsold at
        the termination of the offering.

        (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in this
registration statement shall be deemed to be a new registration statement
relating to the securities offered herein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

        (c) 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 provisions described under Item 15
above, 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 Securities Act of 1933 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 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
Securities Act of 1933 and will be governed by the final adjudication of such
issue.
