                                    THE NOTES

               Section 2.01 Form. The Class A-1 Notes, the Class A-2 Notes, the
Class A-3 Notes and the Class A-4 Notes, in each case together with the
Indenture Trustee's certificate of authentication, shall be in substantially the
forms set forth as Exhibits B, C, D and E to this Indenture with such
appropriate insertions, omissions, substitutions and other variations as are
required or permitted by this Indenture and may have such letters, numbers or
other marks of identification and such legends or endorsements placed thereon as
may, consistently herewith, be determined by the officers executing such Notes,
as evidenced by their execution of the Notes. Any portion of the text of any
Note may be set forth on the reverse thereof, with an appropriate reference
thereto on the face of the Note.

        Each Note shall be dated the date of its authentication. The terms of
the Notes set forth in Exhibits B, C, D and E hereto are part of the terms of
this Indenture.

               Section 2.02 Execution, Authentication and Delivery. The Notes
shall be executed on behalf of the Issuer by the Owner Trustee, as provided in
the Trust Agreement. The signature of any such Authorized Officer on the Notes
may be manual or facsimile. Notes bearing the manual or facsimile signature of
individuals who were at any time Authorized Officers of the Issuer shall bind
the Issuer, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Notes or did
not hold such offices at the date of such Notes.

        The Indenture Trustee shall, upon receipt of an Issuer Order,
authenticate and deliver for original issue the following aggregate principal
amount of Notes: (i) $73,000,000 of Class A-1 Notes, (ii) $98,000,000 of Class
A-2 Notes, (iii) $126,000,000 of Class A-3 Notes, and (iv) $103,000,000 of Class
A-4 Notes. The aggregate principal amount of Class A-1 Notes, Class A-2 Notes,
Class A-3 Notes and Class A-4 Notes outstanding at any time may not exceed such
respective amounts, except as otherwise provided in Section 2.05.

        Each Note shall be dated the date of its authentication. The Notes shall
be issuable as registered Notes in the minimum denomination of $1,000 and in
integral multiples of $1,000 in excess thereof, except that one Note of each
Class may be issued in a different denomination.

        No Note shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose, unless there appears on such Note a
certificate of authentication substantially in the form provided for in the
forms of Notes attached as exhibits to this Indenture executed by the Indenture
Trustee by the manual signature of one of its authorized signatories, and such
certificate upon any Note shall be conclusive evidence, and the only evidence,
that such Note has been duly authenticated and delivered hereunder.

               Section 2.03 Temporary Notes. Pending the preparation of
definitive Notes, the Issuer may execute, and upon receipt of an Issuer Order
the Indenture Trustee shall authenticate and deliver, temporary Notes that are
printed, lithographed, typewritten, mimeographed or otherwise produced, of the
tenor of the definitive Notes in lieu of which they are issued and with


                                      -8-
<PAGE>   14

such variations not inconsistent with the terms of this Indenture as the
officers executing such Notes may determine, as evidenced by their execution of
such Notes.

        If temporary Notes are issued, the Issuer will cause definitive Notes to
be prepared without unreasonable delay. After the preparation of definitive
Notes, the temporary Notes shall be exchangeable for definitive Notes upon
surrender of the temporary Notes at the office or agency of the Issuer to be
maintained as provided in Section 3.02, without charge to the Holder. Upon
surrender for cancellation of any one or more temporary Notes, the Issuer shall
execute and the Indenture Trustee shall authenticate and deliver in exchange
therefor a like tenor and principal amount of definitive Notes of authorized
denominations. Until so exchanged, the temporary Notes shall in all respects be
entitled to the same benefits under this Indenture as definitive Notes.

               Section 2.04 Registration; Registration of Transfer and Exchange.
The Issuer shall cause to be kept a register (the "NOTE REGISTER") in which,
subject to such reasonable regulations as it may prescribe, the Issuer shall
provide for the registration of Notes and the registration of transfers of
Notes. The Indenture Trustee shall be "NOTE REGISTRAR" for the purpose of
registering Notes and transfers of Notes as herein provided. Upon any
resignation of any Note Registrar, the Issuer shall promptly appoint a successor
or, if it elects not to make such an appointment, assume the duties of Note
Registrar.

        If a Person other than the Indenture Trustee is appointed by the Issuer
as Note Registrar, the Issuer will give the Indenture Trustee prompt written
notice of the appointment of such Note Registrar and of the location, and any
change in the location, of the Note Register, and the Indenture Trustee shall
have the right to inspect the Note Register at all reasonable times and to
obtain copies thereof, and the Indenture Trustee shall have the right to rely
upon a certificate executed on behalf of the Note Registrar by an Executive
Officer thereof as to the names and addresses of the Holders of the Notes and
the principal amounts and number of such Notes.

        Upon surrender for registration of transfer of any Note at the office or
agency of the Issuer to be maintained as provided in Section 3.02, the Issuer
shall execute, and the Indenture Trustee shall authenticate and the Noteholder
shall obtain from the Indenture Trustee, in the name of the designated
transferee or transferees, one or more new Notes of the same Class in any
authorized denominations, of a like aggregate principal amount.

        At the option of the Holder, Notes may be exchanged for other Notes of
the same Class in any authorized denominations, of a like aggregate principal
amount, upon surrender of the Notes to be exchanged at such office or agency.
Whenever any Notes are so surrendered for exchange, the Issuer shall execute,
and the Indenture Trustee shall authenticate and the Noteholder shall obtain
from the Indenture Trustee, the Notes which the Noteholder making the exchange
is entitled to receive.

        All Notes issued upon any registration of transfer or exchange of Notes
shall be the valid obligations of the Issuer, evidencing the same debt, and
entitled to the same benefits under this Indenture, as the Notes surrendered
upon such registration of transfer or exchange.

        Every Note presented or surrendered for registration of transfer or
exchange shall be duly endorsed by, or be accompanied by a written instrument of
transfer in form satisfactory to the


                                      -9-
<PAGE>   15

Indenture Trustee duly executed by, the Holder thereof or such Holder's attorney
duly authorized in writing, with such signature guaranteed by a commercial bank
or trust company located, or having a correspondent located, in the city of New
York or the city in which the Corporate Trust Office is located, or by a member
firm of a national securities exchange, and such other documents as the
Indenture Trustee may require.

        No service charge shall be made to a Holder for any registration of
transfer or exchange of Notes, but the Issuer or the Indenture Trustee may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any registration of transfer or
exchange of Notes, other than exchanges pursuant to Section 2.03 or 9.06 not
involving any transfer.

        The preceding provisions of this Section notwithstanding, the Issuer
shall not be required to make and the Note Registrar need not register transfers
or exchanges of Notes selected for redemption or of any Note for a period of 15
days preceding the due date for any payment with respect to the Note.

               Section 2.05 Mutilated, Destroyed, Lost or Stolen Notes. If (i)
any mutilated Note is surrendered to the Indenture Trustee, or the Indenture
Trustee receives evidence to its satisfaction of the destruction, loss or theft
of any Note, and (ii) there is delivered to the Indenture Trustee and the
Insurer (unless an Insurer Default shall have occurred and be continuing) such
security or indemnity as may be required by them to hold the Issuer, the
Indenture Trustee and the Insurer harmless, then, in the absence of notice to
the Issuer, the Note Registrar or the Indenture Trustee that such Note has been
acquired by a bona fide purchaser, the Issuer shall execute and upon its request
the Indenture Trustee shall authenticate and deliver, in exchange for or in lieu
of any such mutilated, destroyed, lost or stolen Note, a replacement Note of the
same Class; provided, however, that if any such destroyed, lost or stolen Note,
but not a mutilated Note, shall have become or within seven days shall be due
and payable, or shall have been called for redemption, instead of issuing a
replacement Note, the Issuer may pay such destroyed, lost or stolen Note when so
due or payable or upon the Redemption Date without surrender thereof. If, after
the delivery of such replacement Note or payment of a destroyed, lost or stolen
Note pursuant to the proviso to the preceding sentence, a bona fide purchaser of
the original Note in lieu of which such replacement Note was issued presents for
payment such original Note, the Issuer, the Insurer and the Indenture Trustee
shall be entitled to recover such replacement Note (or such payment) from the
Person to whom it was delivered or any Person taking such replacement Note from
such Person to whom such replacement Note was delivered or any assignee of such
Person, except a bona fide purchaser, and shall be entitled to recover upon the
security or indemnity provided therefor to the extent of any loss, damage, cost
or expense incurred by the Issuer, the Insurer or the Indenture Trustee in
connection therewith.

        Upon the issuance of any replacement Note under this Section, the Issuer
or the Indenture Trustee may require the payment by the Holder of such Note of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in relation thereto and any other reasonable expenses (including the fees and
expenses of the Indenture Trustee or the Note Registrar) connected therewith.

        Every replacement Note issued pursuant to this Section in replacement of
any mutilated, destroyed, lost or stolen Note shall constitute an original
additional contractual obligation of the


                                      -10-
<PAGE>   16

Issuer, whether or not the mutilated, destroyed, lost or stolen Note shall be at
any time enforceable by anyone, and shall be entitled to all the benefits of
this Indenture equally and proportionately with any and all other Notes duly
issued hereunder.

        The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Notes.

               Section 2.06 Persons Deemed Owner. Prior to due presentment for
registration of transfer of any Note, the Issuer, the Indenture Trustee, the
Insurer and any of their respective agents may treat the Person in whose name
any Note is registered (as of the day of determination) as the owner of such
Note for the purpose of receiving payments of principal of and interest, if any,
on such Note and for all other purposes whatsoever, whether or not such Note be
overdue, and none of the Issuer, the Insurer, the Indenture Trustee nor any of
their respective agents shall be affected by notice to the contrary.

               Section  2.07   Payment of Principal and Interest; Defaulted
        Interest.

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

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

        Class;

                      (ii) the Redemption Date;

                      (iii) if an Event of Default shall have occurred and be
        continuing, so long as an Insurer Default shall not have occurred and be
        continuing, the date on which the Insurer shall have declared the Notes
        to be immediately due and payable in the manner provided in Section
        5.02; or

                      (iv) if an Event of Default shall have occurred and be
        continuing and if an Insurer Default has occurred and is continuing, the
        date on which Holders representing not less than 66 2/3% of the
        Outstanding Amount of the Notes, acting together as a single Class, have
        declared the Notes to be immediately due and payable in the manner
        provided in Section 5.02.

All principal payments on each Class of Notes shall be made pro rata to the
Noteholders of such Class entitled thereto. The Indenture Trustee shall notify
the Person in whose name a Note is registered at the close of business on the
Record Date preceding the Distribution Date on which the Issuer expects that the
final installment of principal, of and interest on, such Note will be paid. Such
notice shall be mailed within five Business Days of such Distribution Date (or,
in the case of Notes registered in the name of Cede & Co., as nominee of DTC,
such notice shall be provided within one Business Day of such Distribution Date)
or receipt of notice of termination of the Trust pursuant to Section 9.01(c) of
the Trust Agreement and shall specify that such final installment will be
payable only upon presentation and surrender of such Note and shall specify the
place where such Note may be presented and surrendered for payment of such
installment. Notices in connection with redemptions of Notes shall be mailed to
Noteholders as provided in Section 10.02. In addition, the Administrator shall
notify the Insurer and the Rating Agencies upon the final payment of interest

each case pursuant to the Administration Agreement.

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

               Section 2.09 Book-Entry Notes. The Notes, upon original issuance,
will be issued in the form of a typewritten Note or Notes representing the
Book-Entry Notes, to be delivered to DTC, the initial Depository, by, or on
behalf of, the Issuer. Such Notes shall initially be registered on the Note
Register in the name of Cede & Co., the nominee of the initial Clearing Agency,

               interest on the Notes and the giving of instructions or
               directions hereunder) as the sole Holder of the Notes, and shall
               have no obligation to the Note Owners;

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

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

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

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

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


                                      -13-

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

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

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

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

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

                               COVENANTS

               Section 3.01 Payment of Principal and Interest. The Issuer will
duly and punctually pay the principal of and interest, if any, on the Notes in
accordance with the terms of the Notes and this Indenture. Without limiting the
foregoing, subject to Section 8.02(c), the Issuer will cause to be distributed

of (i) the Class A-1 Notes, to the Class A-1 Noteholders, (ii) the Class A-2
Notes, to the Class A- 2 Noteholders, (iii) the Class A-3 Notes, to the Class
A-3 Noteholders, and (iv) the Class A-4 Notes, to the Class A-4 Noteholders.

               Section 3.02 Maintenance of Office or Agency. The Issuer will or
will cause the Administrator or the Indenture Trustee to maintain in The City of
New York, an office or agency where Notes may be surrendered for registration of
transfer or exchange, and where notices and demands to or upon the Issuer in
respect of the Notes and this Indenture may be served. The Issuer hereby
initially appoints the Indenture Trustee to serve as its agent for the foregoing
purposes. The Issuer will give prompt written notice to the Indenture Trustee of
the location, and of any change in the location, of any such office or agency.
If at any time the Issuer shall fail to maintain any such office or agency or
shall fail to furnish the Indenture Trustee with the address thereof, such
surrenders, notices and demands may be made or served at the Corporate Trust
Office, and the Issuer hereby appoints the Indenture Trustee as its agent to
receive all such surrenders, notices and demands.

               Section 3.03 Money for Payments to be Held in Trust.

               (a) As provided in Section 8.02, all payments of amounts due and
payable with respect to any Notes that are to be made from amounts withdrawn
from the Note Distribution Account after required transfers thereto from the
other Trust Accounts shall be made on behalf of the Issuer by the Paying Agent
(including the Indenture Trustee when serving as a Paying Agent), and no amounts
so withdrawn from the Note Distribution Account for payments of Notes shall be
paid over to the Issuer except as provided in this Section.

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

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

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

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

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


                                      -15-
<PAGE>   21

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

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

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

        The Issuer may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, by Issuer
Order direct any Paying Agent to pay to the Indenture Trustee all sums held in
trust by such Paying Agent, such sums to be held by the Indenture Trustee upon
the same trusts as those upon which the sums were held by such Paying Agent; and
upon such payment by any Paying Agent to the Indenture Trustee, such Paying
Agent shall be released from all further liability with respect to such money.

        Subject to applicable laws with respect to escheat of funds, any money
held by the Indenture Trustee or any Paying Agent in trust for the payment of
any amount due with respect to any Note and remaining unclaimed for two years
after such amount has become due and payable shall be discharged from such trust
and be paid to the Issuer upon receipt of an Issuer Request; and the Holder of
such Note shall thereafter, as an unsecured general creditor, look only to the
Issuer for payment thereof, and all liability of the Indenture Trustee or such
Paying Agent with respect to such trust money shall thereupon cease; provided,
however, that the Indenture Trustee or such Paying Agent, before being required
to make any such repayment, shall at the expense and direction of the Issuer
cause to be published once, in a newspaper published in the English language,
customarily published on each Business Day and of general circulation in The
City of New York, notice that such money remains unclaimed and that, after a
date specified therein, which shall not be less than 30 days from the date of
such publication, any unclaimed balance of such money then remaining will be
repaid to or for the account of the Issuer. The Indenture Trustee may also adopt
and employ, at the expense of the Issuer, any other reasonable means of
notification of such repayment (including, but not limited to, mailing notice of
such repayment to Holders whose Notes have been called but have not been
surrendered for redemption or whose right to or interest in monies due and
payable but not claimed is determinable from the records of the Indenture
Trustee or of any Paying Agent, at the last address of record for each such
Holder).

               Section 3.04 Existence. The Issuer will keep in full effect its
existence, rights and franchises as a business trust under the laws of the State
of Delaware (unless it becomes, or any successor Issuer hereunder is or becomes,
organized under the laws of any other state or of the United States, in which
case the Issuer will keep in full effect its existence, rights and franchises
under the laws of such other jurisdiction) and will obtain and preserve its
qualification to do business in each jurisdiction in which such qualification is
or shall be necessary to protect the validity and enforceability of this
Indenture, the Notes, and the Collateral.


                                      -16-

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

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

                      (ii) maintain or preserve the lien and security interest
               (and the priority thereof) created by this Indenture or carry out
               more effectively the purposes hereof;

                      (iii)  perfect, publish notice of or protect the validity
               of any Grant made or to be made by this Indenture;

                      (iv)   enforce any of the Collateral;

                      (v) preserve and defend title to the Collateral and the
               rights of the Indenture Trustee and the Noteholders in such
               Collateral against the claims of all persons and parties; or

                      (vi)   pay all taxes or assessments levied or assessed
               upon the Collateral when due.

The Issuer hereby designates the Indenture Trustee its agent and
attorney-in-fact to execute all financing statements, continuation statements or
other instruments required to be executed pursuant to this Section and the
Indenture Trustee shall execute all financing statements, continuation
statements or other instruments required to be executed pursuant to this section
upon written notice and instructions from the Issuer.

               Section  3.06 Opinions as to Collateral.

               (a) Promptly after the execution and delivery of this Indenture,
the Issuer shall furnish to the Indenture Trustee and the Insurer an Opinion of
Counsel to the effect that, in the opinion of such counsel, either (i) all
financing statements and continuation statements have been executed and filed
that are necessary to create and continue the Indenture Trustee's first priority
perfected security interest in the Collateral (subject to the rights of the
Insurer under the Insurance Agreement) for the benefit of the Noteholders, and
reciting the details of such filings or referring to prior Opinions of Counsel
in which such details are given, or (ii) no such action shall be necessary to
perfect such security interest.

               (b) Within 90 days after the beginning of each calendar year
beginning with the first calendar year beginning more than three months after
the Closing Date, the Issuer shall furnish to the Indenture Trustee and the
Insurer an Opinion of Counsel, dated as of a date during


                                      -17-
<PAGE>   23

such 90-day period, to the effect that, in the opinion of such counsel, either
(i) all financing statements and continuation statements have been executed and
filed that are necessary to create and continue the Indenture Trustee's first
priority perfected security interest in the Collateral (subject to the rights of
the Insurer under the Insurance Agreement) for the benefit of the Noteholders,
and reciting the details of such filings or referring to prior Opinions of
Counsel in which such details are given, or (ii) no such action shall be
necessary to perfect such security interest.

               Section 3.07 Performance of Obligations; Servicing of Contracts.

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

               (b) The Issuer may contract with or otherwise obtain the
assistance of other Persons (including, without limitation, the Administrator
under the Administration Agreement) to assist it in performing its duties and
obligations under this Indenture, and any performance of such duties by a Person
identified to the Indenture Trustee and the Insurer in an Officer's Certificate
shall be deemed to be action taken by the Issuer. The Indenture Trustee shall
not be responsible for the action or inaction of the Servicer or the
Administrator. Initially, the Issuer has contracted with the Servicer and the
Administrator to assist the Issuer in performing its duties under this
Indenture.

               (c) The Issuer will punctually perform and observe all of its
obligations and agreements contained in this Indenture, the other Basic
Documents and in the instruments and agreements included in the Collateral,
including but not limited to filing or causing to be filed all UCC financing
statements and continuation statements required to be filed by the terms of this
Indenture and the Sale and Servicing Agreement in accordance with and within the
time periods provided for herein and therein. Except as otherwise expressly
provided therein, the Issuer shall not waive, amend, modify, supplement or
terminate any Basic Document or any provision thereof without the consent of the
Indenture Trustee, the Insurer (unless an Insurer Default shall have occurred
and be continuing) and the Holders of at least a majority of the Outstanding
Amount of the Notes.

               (d) If the Issuer shall have actual knowledge of the occurrence
of a Servicer Default, the Issuer shall promptly notify the Indenture Trustee,
the Insurer and each Rating Agency thereof, and shall specify in such notice the
action, if any, the Issuer is taking with respect of such default. If a Servicer
Default shall arise from the failure of the Servicer to perform any of its
duties or obligations under the Sale and Servicing Agreement with respect to the
Contracts, the Issuer shall take all reasonable steps available to it to remedy
such failure.

               (e) Upon the termination of the Servicer by the Insurer pursuant
to Section 7.01 of the Sale and Servicing Agreement or upon the resignation of
the Servicer pursuant to Section 6.04 of the Sale and Servicing Agreement, the
Insurer shall appoint a successor servicer ("SUCCESSOR SERVICER"). Upon the
termination of the Servicer by the Indenture Trustee or the


                                      -18-
<PAGE>   24

Noteholders pursuant to Section 7.01 of the Sale and Servicing Agreement, or
upon the resignation of the Servicer pursuant to Section 6.04 of the Sale and
Servicing Agreement in the event that the Insurer is not entitled to appoint a
successor servicer by operation of Section 9.08 of the Sale and Servicing
Agreement, (i) if the Notes have not been paid in full, the Indenture Trustee
shall be the Successor Servicer, and (ii) if the Notes have been paid in full,
the Owner Trustee, acting at the direction of the Holders of Residual Interest
Instruments evidencing not less than 51% of the Percentage Interests, shall
appoint a Successor Servicer. The Successor Servicer shall succeed to all the
responsibilities, duties and liabilities of the Servicer under the Sale and
Servicing Agreement. Notwithstanding the foregoing, if the Notes have not been
paid in full, the Indenture Trustee may, if it shall be unwilling to act, or
shall, if it shall be legally unable to so act, appoint, or petition a court of
competent jurisdiction (with any related costs to be at the sole expense of the
Issuer) to appoint, any established financial institution, having a net worth of
not less than $50,000,000 and whose regular business shall include the servicing
of automotive retail installment sales contracts, as the successor to the
Servicer under the Sale and Servicing Agreement. If the Indenture Trustee shall
succeed to the Servicer's duties as servicer of the Contracts as provided
herein, it shall do so in its individual capacity and not in its capacity as
Indenture Trustee and, accordingly, the provisions of Article Six shall be
inapplicable to the Indenture Trustee in its duties as the successor to the
Servicer and the servicing of the Contracts. In case the Indenture Trustee shall
become successor to the Servicer under the Sale and Servicing Agreement, the
Indenture Trustee shall be entitled to appoint as Servicer one of its
Affiliates, provided that it shall not be liable for the actions and omissions
of any such Affiliate in such capacity as Successor Servicer appointed with due
care.

               (f) Upon any termination of the Servicer's rights and powers
pursuant to the Sale and Servicing Agreement, the Issuer shall promptly notify
the Indenture Trustee and the Insurer. As soon as a Successor Servicer is
appointed, the Issuer shall notify the Indenture Trustee and the Insurer of such
appointment, specifying in such notice the name and address of such Successor
Servicer.

               (g) The Issuer agrees that it will not waive timely performance
or observance by the Servicer or the Seller of their respective duties under the
Basic Documents: (i) without the prior consent of the Insurer (unless an Insurer
Default shall have occurred and be continuing) or (ii) if the effect thereof
would adversely affect the Holders of the Notes.

               Section  3.08   Negative Covenants.  Until the Termination Date,
the Issuer shall not:

                      (i) except as expressly permitted by the Basic Documents,
               sell, transfer, exchange or otherwise dispose of any of the
               properties or assets of the Issuer, including those included in
               the Collateral, unless directed to do so by the Indenture Trustee
               with the prior written consent of the Insurer;

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


                                      -19-
<PAGE>   25

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

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

               Section 3.09 Annual Statement as to Compliance. The Issuer will
deliver to the Indenture Trustee and the Insurer, on or before 120 days after
the end of each fiscal year of the Issuer (commencing with the fiscal year ended
December 31, 2000), an Officer's Certificate stating, as to the Authorized
Officer signing such Officer's Certificate, that:

                      (i) a review of the activities of the Issuer during such
               year and of performance under this Indenture has been made under
               such Authorized Officer's supervision; and

                      (ii) to the best of such Authorized Officer's knowledge,
               based on such review, the Issuer has complied with all conditions
               and covenants under this Indenture throughout such year, or, if
               there has been a default in the compliance of any such condition
               or covenant, specifying each such default known to such
               Authorized Officer and the nature and status thereof.

               Section  3.10 Issuer May Consolidate, etc. Only on Certain Terms.

               (a) The Issuer shall not consolidate or merge with or into any
other Person, unless:

                      (i) the Person (if other than the Issuer) formed by or
               surviving such consolidation or merger shall be a Person
               organized and existing under the laws of the United States or any
               State and shall expressly assume, by an indenture supplemental

               (a) the delivery to the Insurer of a claim for payment under the

<PAGE>   31

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

               (d) (i) default in the observance or performance of any covenant
or agreement of the Issuer made in this Indenture (other than a covenant or

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

been cured within 30 days after notice thereof is given to the Issuer by the
Indenture Trustee or the Insurer, or to the Issuer and the Indenture Trustee by
the Holders of at least 25% of the Outstanding Amount of the Notes acting
together as a single Class;

               (e) the filing of a decree or order for relief by a court having
jurisdiction in the premises in respect of the Issuer or any substantial part of
the Collateral in an involuntary case under any applicable federal or state
bankruptcy, insolvency or other similar law now or hereafter in effect, or
appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator or
similar official of the Issuer or for any substantial part of the Collateral, or
ordering the winding-up or liquidation of the Issuer's affairs, and such decree
or order shall remain unstayed and in effect for a period of 60 consecutive

               (f) the commencement by the Issuer of a voluntary case under any
applicable federal or state bankruptcy, insolvency or other similar law now or

to the appointment or taking possession by a receiver, liquidator, assignee,

substantial part of the Collateral, or the making by the Issuer of any general
assignment for the benefit of creditors, or the failure by the Issuer generally
to pay its debts as such debts become due, or the taking of action by the Issuer
in furtherance of any of the foregoing;

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

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

<PAGE>   32

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

               (b) If an Insurer Default shall have occurred and be continuing
and an Event of Default shall have occurred and be continuing, the Indenture
Trustee shall, if so requested in writing by Holders representing at least
662/3% of the aggregate Outstanding Amount of the Notes, acting together as a
single Class, upon prior written notice to each Rating Agency, declare that all
the Notes become immediately due and payable, and upon any such declaration the
unpaid principal amount of the Notes, together with accrued and unpaid interest
thereon, shall become immediately due and payable.

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

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

               (a) The Issuer covenants that, if the Notes are accelerated
following the occurrence of an Event of Default, the Issuer will, upon demand of
the Indenture Trustee, pay to the Indenture Trustee, for the benefit of the
Holders of the Notes, the whole amount then due and payable on such Notes for
principal and interest, with interest upon the overdue principal, and, to the
extent payment at such rate of interest shall be legally enforceable, upon
overdue installments of interest, at the applicable Interest Rate and in
addition thereto such further amount as shall be sufficient to cover the costs
and expenses of collection, including the reasonable compensation, expenses and
disbursements of the Indenture Trustee and its agents and counsel.

               (b) If an Event of Default shall have occurred and be continuing,
the Indenture Trustee shall (i) if no Insurer Default shall have occurred and be
continuing, at the direction of the Insurer, or (ii) if an Insurer Default shall
have occurred and be continuing, at the direction of Holders representing at
least 662/3% of the Outstanding Amount of the Notes, acting together as a single
Class, as more particularly provided in Section 5.04, proceed to protect and
enforce the rights of the Noteholders, by such appropriate Proceedings as the
Indenture Trustee shall deem most effective to protect and enforce any such
rights, whether for the specific enforcement of any covenant or agreement in
this Indenture or in aid of the exercise of any power granted herein, or to
enforce any other proper remedy or legal or equitable right vested in the
Indenture Trustee by this Indenture or by law.

               (c) In case there shall be pending, relative to the Issuer or any
other obligor upon the Notes or any Person having or claiming an ownership
interest in the Collateral, Proceedings under Title 11 of the United States Code
or any other applicable federal or state

bankruptcy, insolvency or other similar law, or in case a receiver, assignee or
trustee in bankruptcy or reorganization, liquidator, sequestrator or similar
official shall have been appointed for or taken possession of the Issuer or its
property or such other obligor or Person, or in case of any other comparable
judicial Proceedings relative to the Issuer or other obligor upon the Notes, or
to the creditors or property of the Issuer or such other obligor, the Indenture
Trustee, irrespective of whether the principal of any Notes shall then be due
and payable as therein expressed or by declaration or otherwise and irrespective
of whether the Indenture Trustee shall have made any demand pursuant to the
provisions of this Section, shall be entitled and empowered, by intervention in
such Proceedings or otherwise:

                      (i) to file and prove a claim or claims for the whole
               amount of principal and interest owing and unpaid in respect of
               the Notes and to file such other papers or documents as may be
               necessary or advisable in order to have the claims of the

               Indenture Trustee, and their respective agents, attorneys and
               counsel, and for reimbursement of all expenses and liabilities
               incurred by the Indenture Trustee and each predecessor Indenture
               Trustee, except as a result of negligence or bad faith) and of
               the Noteholders allowed in such Proceedings;

                      (ii) unless prohibited by applicable law and regulations,
               to vote on behalf of the Holders of Notes in any election of a
               trustee, a standby trustee or Person performing similar functions
               in any such Proceedings;

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

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

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

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

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

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

               Section 5.04 Remedies.

               (a) If (i) an Event of Default shall have occurred and be
continuing, the Indenture Trustee shall (subject to Section 5.04(b) below and
Section 5.05), if no Insurer Default shall have occurred and be continuing, at
the direction of the Insurer, or (ii) if an Event of Default shall have occurred
and be continuing, the Indenture Trustee shall (subject to Section 5.04(b) below
and Section 5.05), if an Insurer Default shall have occurred and be continuing,
at the direction of Holders representing at least 662/3% of the Outstanding
Amount of the Notes, acting together as a single Class, take one or more of the
following actions as so directed:

                      (i) institute Proceedings in its own name and as or on
               behalf of a trustee of an express trust for the collection of all
               amounts then payable on the Notes or under this Indenture with
               respect thereto, whether by declaration or otherwise, enforce any
               judgment obtained, and collect from the Issuer and any other
               obligor upon such Notes monies adjudged due;

                      (ii) institute Proceedings from time to time for the
               complete or partial foreclosure of this Indenture with respect to
               the Collateral;

                      (iii) exercise any remedies of a secured party under the
               UCC and any other remedy available to the Indenture Trustee and
               take any other appropriate action to protect and enforce the
               rights and remedies of the Indenture Trustee on behalf of the
               Noteholders under this Indenture or the Notes;

                      (iv) sell or cause the Servicer to otherwise liquidate the
               Collateral or any portion thereof or rights or interests therein,
               at one or more public or private sales called and conducted in
               any manner permitted by law and deliver the proceeds of such sale
               or liquidation to the Indenture Trustee for distribution in
               accordance with the terms of this Indenture; and

                      (v) maintain possession of the Collateral.

               (b) Notwithstanding the foregoing,


                                      -29-
<PAGE>   35

                      (i) in the event that the Indenture Trustee is acting at
               the direction of the Insurer, so long as an Insurer Default shall
               not have occurred and be continuing, if an Event of Default shall
               have occurred and be continuing, the Insurer shall not have the
               right to cause the Indenture Trustee or the Servicer to, and
               neither the Indenture Trustee nor the Servicer shall, liquidate
               the Collateral in whole or in part if the proceeds of such sale
               or liquidation would not be sufficient to pay all outstanding
               principal of and accrued interest on the Notes; and

                      (ii) in the event that the Indenture Trustee is acting at
               the direction of Holders representing at least 662/3% of the
               Outstanding Amount of the Notes, acting together as a single
               Class, the Noteholders shall not have the right to direct the
               Indenture Trustee or the Servicer to, and neither the Indenture
               Trustee nor the Servicer shall, liquidate the Collateral in whole
               or in part unless (A) an Indenture Event of Default as specified
               in Section 5.01(b), (c), (e) or (f) shall have occurred and be
               continuing and in any case the Insurer shall have failed to make
               a payment required under the Policy in accordance with its terms
               or (B) (1) an Indenture Event of Default as specified in Section
               5.01(a) or (d) shall have occurred and be continuing, (2) the
               Insurer shall not have failed to make a payment required under
               the Policy in accordance with its terms and (3) the proceeds of
               such sale or liquidation would be sufficient to pay all
               outstanding principal of and accrued interest on the Notes and
               all amounts owing to the Insurer pursuant to the terms of the
               Insurance Agreement. In the event of a liquidation of the
               Collateral pursuant to clause (B), the Policy will not be
               available to cover losses to Noteholders resulting from such
               liquidation, and the Policy shall be terminated and the Insurer
               shall have no further obligation thereunder.

               (c) In determining the sufficiency or insufficiency of the
proceeds of a sale or liquidation of the Collateral to pay all amounts required
pursuant to Section 5.04(b)(i) or (ii) above, the Indenture Trustee may, but
need not, at the sole expense of the Issuer obtain and rely upon an opinion of
an Independent investment banking or accounting firm of national reputation as
to the feasibility of such proposed action and as to the sufficiency of the
Collateral for such purpose.

               (d) In the event that the Indenture Trustee is directed to sell
or to cause the Servicer to otherwise liquidate the Collateral or any portion
thereof or rights or interests therein pursuant to Section 5.04(a)(iv) above,
the Indenture Trustee shall, prior to any such public or private sales, notify
all Residual Interestholders of the proposed sale. The Indenture Trustee shall
provide the Residual Interestholders the right to match the highest liquidation
price offered at any such sale.

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

               Section 5.06 Priorities.


                                      -30-
<PAGE>   36

               (a) If the Notes have been declared to be due and payable under
Section 5.02 following an Indenture Event of Default and such declaration and
its consequences have not been rescinded and annulled, any money collected by
the Indenture Trustee with respect to the Collateral or the Notes pursuant to
this Article or otherwise and any money that may then be held or thereafter
received by the Indenture Trustee with respect to the Collateral or the Notes
(excluding any payments made under the Policy), shall be applied in the
following order and priority:

                      first, to the Servicer, to pay any unpaid Servicing Fee;

                      second, to pay any accrued and unpaid fees and expenses of
               the Owner Trustee, the Indenture Trustee and the Trust Agent
               without preference or priority of any kind;

                      third, to the holders of Class A Notes, to pay accrued
               interest on each Class of Class A Notes on a pro rata basis based
               on the interest accrued (including, to the extent permitted by
               applicable law, interest accrued on any
               interest accrued but not timely paid) on each Class of Class A
               Notes at the related Interest Rate for such Class;

                      fourth, to the holders of Class A Notes, to pay principal
               on each Class of Class A Notes on a pro rata basis based on the
               Outstanding Amount of each Class of Class A Notes, until the
               Outstanding Amount of each such Class of Notes is reduced to
               zero;

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

                      sixth, any excess amounts remaining after making the
               distributions described in clauses first through fifth to the
               Spread Account, to be applied in accordance with the Insurance
               Agreement.

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

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

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

                      (ii) the Holders of not less than 25% of the Outstanding
               Amount of the Notes, acting together as a single Class, have made
               written request to the Indenture Trustee to institute such
               Proceeding in respect of such Event of Default in its own name as
               Indenture Trustee hereunder;


                                      -31-
<PAGE>   37

                      (iii) such Holder or Holders have offered to the Indenture
               Trustee reasonable indemnity against the costs, expenses and
               liabilities to be incurred in complying with such request;

                      (iv) the Indenture Trustee for 60 days after its receipt
               of such notice, request and offer of indemnity has failed to
               institute such Proceedings;

                      (v) no direction inconsistent with such written request
               has been given to the Indenture Trustee during such 60-day period
               by the Holders of a majority of the Outstanding Amount of the
               Notes, acting together as a single Class; and

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

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

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

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

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

               Section 5.10 Rights and Remedies Cumulative. No right or remedy
herein conferred upon or reserved to the Indenture Trustee, the Insurer or to
the Noteholders is intended to be exclusive of any other right or remedy, and
every right and remedy shall, to the extent permitted by law, be cumulative and
in addition to every other right and remedy given hereunder


                                      -32-
<PAGE>   38

or now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

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

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

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

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

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

Notwithstanding the rights of Noteholders set forth in this Section, subject to
Section 6.01, the Indenture Trustee need not take any action that it determines,
in its sole discretion, might involve it in liability or might materially
adversely affect the rights of any Noteholders not consenting to such action.

               Section 5.13 Waiver of Past Defaults. Prior to the declaration of
the acceleration of the maturity of the Notes as provided in Section 5.02, the
Insurer or the Holders of Notes representing not less than a majority of the
Outstanding Amount of the Notes, acting together as a single Class, with the
consent of the Insurer may waive any past Default or Event of Default and its
consequences except a Default (a) in the payment of or interest on any of the
Notes or (b) in respect of a covenant or provision hereof that cannot be
modified or amended without the consent of the Holder of each Note, as
applicable. In the case of any such waiver, the Issuer, the Indenture Trustee,
the Insurer and the Holders of the Notes shall be restored to their former
positions and rights hereunder, respectively; but no such waiver shall extend to
any subsequent or other Default or impair any right consequent thereto.

        Upon any such waiver, such Default shall cease to exist and be deemed to
have been cured and not to have occurred, and any Event of Default arising
therefrom shall be deemed to have been cured and not to have occurred, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other Default or Event of Default or impair any right consequent thereto.


                                      -33-
<PAGE>   39

               Section 5.14 Undertaking for Costs. All parties to this Indenture
agree, and each Holder of any Note by such Holder's acceptance thereof shall be
deemed to have agreed, that any court may in its discretion require, in any suit
for the enforcement of any right or remedy under this Indenture, or in any suit
against the Indenture Trustee for any action taken, suffered or omitted by it as
Indenture Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to (i) any suit instituted by the
Indenture Trustee, (ii) any suit instituted by any Noteholder, or group of
Noteholders, in each case holding in the aggregate more than 10% of the
Outstanding Amount of the Notes or (iii) any suit instituted by any Noteholder
for the enforcement of the payment of principal of or interest on any Note on or
after the respective due dates expressed in such Note and in this Indenture (or,
in the case of redemption, on or after the Redemption Date).

               Section 5.15 Waiver of Stay or Extension Laws. The Issuer
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead or in and manner whatsoever, claim or take the
benefit or advantage of, any stay or extension law wherever enacted, now or at
any time hereafter in force, that may affect the covenants or the performance of
this Indenture; and the Issuer (to the extent that it may lawfully do so) hereby
expressly waives all benefit or advantages of any such law, and covenants that
it will not hinder, delay or impede the execution of any power herein granted to
the Indenture Trustee, but will suffer and permit the execution of every such
power as though no such law had been enacted.

               Section 5.16 Action on Notes. The Indenture Trustee's right to
seek and recover judgment on the Notes or under this Indenture shall not be
affected by the seeking, obtaining or application of any other relief under or
with respect to this Indenture. Neither the lien of this Indenture nor any
rights or remedies of the Indenture Trustee or the Noteholders shall be impaired
by the recovery of any judgment by the Indenture Trustee against the Issuer or
by the levy of any execution under such judgment upon any portion of the
Collateral or upon any of the assets of the Issuer. Any money or property
collected by the Indenture Trustee shall be applied in accordance with Section
5.06.

               Section 5.17 Performance and Enforcement of Certain Obligations.

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

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

                                   ARTICLE VI

                              THE INDENTURE TRUSTEE

               Section  6.01 Duties of Indenture Trustee.

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

               (b) Except during the continuance of an Event of Default of which
a Responsible Officer of the Indenture Trustee shall have actual knowledge or
written notice:

                      (i) the Indenture Trustee undertakes to perform such
               duties and only such duties as are specifically set forth in this
               Indenture and no implied covenants or obligations shall be read
               into this Indenture against the Indenture Trustee; and

                      (ii) in the absence of bad faith on its part, the
               Indenture Trustee may conclusively rely, as to the truth of the
               statements and the correctness of the opinions expressed therein,
               upon certificates or opinions furnished to the Indenture Trustee
               and conforming to the requirements of this Indenture; however,
               the Indenture Trustee shall examine the certificates and opinions
               to determine whether or not they conform to the requirements of
               this Indenture and the other Basic Documents to which the
               Indenture Trustee is a party; provided, however, that the
               Indenture Trustee shall not be responsible for the accuracy or
               content of any of the aforementioned documents and the Indenture
               Trustee shall have no obligation to verify, re-compute or
               recalculate any numerical information provided to it pursuant to
               the Basic Documents.

               (c) The Indenture Trustee may not be relieved from liability for
its own negligent action, its own negligent failure to act or its own wilful
misconduct, except that:


                                      -35-
<PAGE>   41

                      (i) this paragraph does not limit the effect of Section
               6.01(b);

                      (ii) the Indenture Trustee shall not be liable for any
               error of judgment made in good faith by a Responsible Officer
               unless it is proved that the Indenture Trustee was negligent in
               ascertaining the pertinent facts; and

                      (iii) the Indenture Trustee shall not be liable with
               respect to any action it takes or omits to take in good faith in
               accordance with a direction received by it pursuant to Section
               5.12.

               (d) Every provision of this Indenture that in any way relates to
the Indenture Trustee is subject to paragraphs (a), (b) and (c) of this Section.

               (e) The Indenture Trustee shall not be liable for interest on any
money received by it.

               (f) Money held in trust by the Indenture Trustee need not be
segregated from other funds except to the extent required by law or the terms of
this Indenture or the Sale and Servicing Agreement.

               (g) No provision of this Indenture shall require the Indenture
Trustee to expend or risk its own funds or otherwise incur financial liability
in the performance of any of its duties hereunder or in the exercise of any of
its rights or powers, if it shall have reasonable grounds to believe that
repayments of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

               (h) Every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Indenture Trustee
shall be subject to the provisions of this Section and to the provisions of the
TIA.

               (i) The Indenture Trustee shall, and hereby agrees that it will
(i) perform all of the obligations and duties required of it under the Sale and
Servicing Agreement and (ii) hold the Policy in trust, and will hold any
proceeds of any claim on the Policy in trust solely for application as provided
in the Sale and Servicing Agreement.

               (j) Except as otherwise required or permitted by the TIA, nothing
contained herein shall be deemed to authorize the Indenture Trustee to engage in
any business operations or any activities other than those set forth in this
Indenture. Specifically, the Indenture Trustee shall have no authority to engage
in any business operations, acquire any assets other than those specifically
included in the Collateral under this Indenture or otherwise vary the assets
held by the Trust. Similarly, the Indenture Trustee shall have no discretionary
duties other than performing those ministerial acts set forth above necessary to
accomplish the purpose of this Trust as set forth in this Indenture.

               (k) The Indenture Trustee shall not be liable in its individual
capacity with respect to any action taken, suffered or omitted to be taken by it
in good faith in accordance with this Indenture or at the direction of a
majority of the Outstanding Amount of Notes, acting together as a single Class,
relating to the time, method and place of conducting any proceeding


                                      -36-
<PAGE>   42

for any remedy available to the Indenture Trustee, or exercising or omitting to
exercise any trust or power conferred upon the Indenture Trustee, under this
Indenture.

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

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

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

               Section 6.02 Rights of Indenture Trustee.

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

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

               (c) The Indenture Trustee may execute any of the trusts or powers
hereunder or perform any duties hereunder either directly or by or through
agents or attorneys or a custodian or nominee and the Indenture Trustee shall
not be responsible for any misconduct or


                                      -37-
<PAGE>   43

negligence on the part of any such agent, attorney, custodian or nominee
appointed by the Indenture Trustee with due care.

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

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

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

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

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

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


                                      -38-
<PAGE>   44

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

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

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

               Section 6.07 Compensation and Indemnity. The Issuer shall cause
the Servicer to pay to the Indenture Trustee from time to time reasonable
compensation for its services. The Indenture Trustee's compensation shall not be
limited by any law on compensation of a trustee of an express trust. The Issuer
shall cause the Servicer to reimburse the Indenture Trustee for all reasonable
out-of-pocket expenses incurred or made by it, including costs of collection, in
addition to the compensation for its services. Such expenses shall include the
reasonable compensation and expenses and disbursements and advances of the
Indenture Trustee's agents, counsel, accountants and experts. The Issuer shall,
or shall cause the Administrator to, indemnify the Indenture Trustee against any
and all loss, liability or expense (including attorneys' fees) incurred by it in
connection with the administration of this trust and the performance of its
duties hereunder. The Indenture Trustee shall notify the Issuer and the
Administrator promptly of any claim for which it may seek indemnity. Failure by
the Indenture Trustee to so notify the Issuer and the Administrator shall not
relieve the Issuer or the Administrator of its obligations hereunder. The Issuer
shall, or shall cause the Administrator to, defend any such claim, and the
Indenture Trustee may have separate counsel and the Issuer shall, or shall cause
the Administrator to, pay the fees and expenses of such counsel. Neither the
Issuer nor the Administrator need reimburse any expense or indemnify against any
loss, liability or expense incurred by the Indenture Trustee through the
Indenture Trustee's own willful misconduct, negligence or bad faith.

        The Issuer's obligations to the Indenture Trustee pursuant to this
Section shall survive the resignation or removal of the Indenture Trustee and
the discharge of this Indenture. When the Indenture Trustee incurs expenses
after the occurrence of a Default specified in Section 5.01(e) or (f) with
respect to the Issuer, the expenses are intended to constitute expenses of
administration under Title 11 of the United States Code or any other applicable
federal or state bankruptcy, insolvency or similar law.

               Section 6.08 Replacement of Indenture Trustee. The Indenture
Trustee may resign at any time by so notifying the Issuer, the Servicer and the
Insurer. The Issuer, may, with

                                      -39-
<PAGE>   45

the consent of the Insurer, and, at the request of the Insurer shall, remove the
Indenture Trustee, unless an Insurer Default shall have occurred and be
continuing, if:

                      (i) the Indenture Trustee fails to comply with Section
               6.11;

                      (ii) a court having jurisdiction in the premises in
               respect of the Indenture Trustee in an involuntary case or
               proceeding under federal or state banking or bankruptcy laws, as
               now or hereafter constituted, or any other applicable federal or
               state bankruptcy, insolvency or other similar law, shall have
               entered a decree or order granting relief or appointing a
               receiver, liquidator, assignee, custodian, trustee, conservator,
               sequestrator (or similar official) for the Indenture Trustee or
               for any substantial part of the Indenture Trustee's property, or
               ordering the winding-up or liquidation of the Indenture Trustee's
               affairs, provided any such decree or order shall have continued
               unstayed and in effect for a period of 30 consecutive days;

                      (iii) the Indenture Trustee commences a voluntary case
               under any federal or state banking or bankruptcy laws, as now or
               hereafter constituted, or any other applicable federal or state
               bankruptcy, insolvency or other similar law, or consents to the
               appointment of or taking possession by a receiver, liquidator,
               assignee, custodian, trustee, conservator, sequestrator or other
               similar official for the Indenture Trustee or for any substantial
               part of the Indenture Trustee's property, or makes any assignment
               for the benefit of creditors or fails generally to pay its debts
               as such debts become due or takes any corporate action in
               furtherance of any of the foregoing; or

                      (iv) the Indenture Trustee otherwise becomes incapable of
               acting.

        If the Indenture Trustee resigns or is removed or if a vacancy exists in
the office of Indenture Trustee for any reason (the Indenture Trustee in such
event being referred to herein as the retiring Indenture Trustee), the Issuer
shall promptly appoint a successor Indenture Trustee acceptable to the Insurer.

         A successor Indenture Trustee shall deliver a written acceptance of its
appointment to the retiring Indenture Trustee and to the Issuer. Thereupon the
resignation or removal of the retiring Indenture Trustee shall become effective,
and the successor Indenture Trustee shall have all the rights, powers and duties
of the Indenture Trustee under this Indenture. The Issuer or the successor
Indenture Trustee shall mail a notice of its succession to Noteholders. The
retiring Indenture Trustee shall promptly transfer all property held by it as
Indenture Trustee to the successor Indenture Trustee.

        If a successor Indenture Trustee does not take office within 30 days
after the retiring Indenture Trustee resigns or is removed, the retiring
Indenture Trustee, the Issuer or the Holders of a majority of the Outstanding
Amount of the Notes may petition any court of competent jurisdiction for the
appointment of a successor Indenture Trustee.


                                      -40-
<PAGE>   46

        If the Indenture Trustee fails to comply with Section 6.11, any
Noteholder may petition any court of competent jurisdiction for the removal of
the Indenture Trustee and the appointment of a successor Indenture Trustee.

        Any resignation or removal of the Indenture Trustee and appointment of a
successor Indenture Trustee pursuant to the provisions of this Section shall not
become effective until acceptance of appointment by the successor Indenture
Trustee pursuant to this Section and payment of all fees and expenses owed to
the outgoing Indenture Trustee. Notwithstanding the replacement of the Indenture
Trustee pursuant to this Section, the retiring Indenture Trustee shall be
entitled to payment or reimbursement of such amounts as such Person is entitled
pursuant to Section 6.07.

               Section 6.09 Successor Indenture Trustee by Merger. If the
Indenture Trustee consolidates with, merges or converts into, or transfers all
or substantially all its corporate trust business or assets to, another
corporation or banking association, the resulting, surviving or transferee
corporation without any further act shall be the successor Indenture Trustee;
provided, that such corporation or banking association shall be otherwise
qualified and eligible under Section 6.11. The Indenture Trustee shall (unless
the Indenture Trustee is The Chase Manhattan Bank) provide the Insurer and each
Rating Agency prompt notice of any such transaction.

        In case at the time such successor by merger, conversion or
consolidation to the Indenture Trustee shall succeed to the trusts created by
this Indenture any of the Notes shall have been authenticated but not delivered,
any such successor to the Indenture Trustee may adopt the certificate of
authentication of any predecessor trustee, and deliver such Notes so
authenticated; and in case at that time any of the Notes shall not have been
authenticated, any successor to the Indenture Trustee may authenticate such
Notes either in the name of any predecessor hereunder or in the name of the
successor to the Indenture Trustee; and in all such cases such certificates
shall have the full force and effect of the certificate of the Indenture Trustee
pursuant to the Notes or this Indenture.

               Section 6.10 Appointment of Co-Indenture Trustee or Separate
Indenture Trustee.

               (a) Notwithstanding any other provision of this Indenture, at any
time, for the purpose of meeting any legal requirement of any jurisdiction in
which any part of the Collateral may at the time be located, the Indenture
Trustee shall have the power and may execute and deliver all instruments to
appoint one or more Persons to act as a co-trustee or co-trustees, jointly with
the Indenture Trustee, or separate trustee or separate trustees, of all or any
part of the Trust, and to vest in such Person or Persons, in such capacity and
for the benefit of the Noteholders, such title to the Collateral, or any part
hereof, and, subject to the other provisions of this Section, such powers,
duties, obligations, rights and trusts as the Indenture Trustee may consider
necessary or desirable. No co-trustee or separate trustee hereunder shall be
required to meet the terms of eligibility as a successor Indenture Trustee under
Section 6.11 and no notice to Noteholders of the appointment of any co-trustee
or separate trustee shall be required under Section 6.08.

               (b) Every separate trustee and co-trustee shall, to the extent
permitted by law, be appointed and act subject to the following provisions and
conditions:


                                      -41-
<PAGE>   47

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

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

                      (iii) the Indenture Trustee may at any time accept the
               resignation of or remove any separate trustee or co-trustee.

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

               (d) Any separate trustee or co-trustee may at any time constitute
the Indenture Trustee, its agent or attorney-in-fact with full power and
authority, to the extent not prohibited by law, to do any lawful act under or in
respect of this Indenture on its behalf and in its name. If any separate trustee

Section 6.07, the Indenture Trustee may, and when required by the provisions of
this Indenture shall, execute instruments to release property from the lien of
this Indenture, or convey the Indenture Trustee's interest in the same, in a
manner and under circumstances that are not inconsistent with the provisions of
this Indenture. No party relying upon an instrument executed by the Indenture
Trustee as provided in this Article shall be bound to ascertain the Indenture
Trustee's authority, inquire into the satisfaction of any conditions precedent
or see to the application of any monies.

               (b) The Indenture Trustee shall, at such time as there are no
Notes Outstanding and all sums due the Indenture Trustee pursuant to Section
6.07 have been paid, release any remaining portion of the Collateral that
secured the Notes from the lien of this Indenture and release to the Issuer or
any other Person entitled thereto any funds then on deposit in the Trust
Accounts. The Indenture Trustee shall release property from the lien of this
Indenture pursuant to this Section 8.04(b) only upon receipt of an Issuer

required by the TIA) Independent Certificates in accordance with TIA Sections

involved, and the Indenture Trustee shall also require, as a condition to such
action, an Opinion of Counsel, in form and substance satisfactory to the
Indenture Trustee (and not at the expense of the Indenture Trustee), stating the
legal effect of any such action, outlining the steps required to complete the
same, and concluding that all conditions precedent to the taking of such action
have been complied with and such action will not


                                      -46-
<PAGE>   52

materially and adversely impair the security for the Notes or the rights of the
Noteholders in contravention of the provisions of this Indenture; provided,
however, that such Opinion of Counsel shall not be required to express an
opinion as to the fair value of the Collateral. Counsel rendering any such
opinion may rely, without independent investigation, on the accuracy and
validity of any certificate or other instrument delivered to the Indenture
Trustee in connection with any such action.

               (b) The Issuer and the Indenture Trustee, when authorized by an
Issuer Order, may, also without the consent of any of the Holders of the Notes
but with the consent of the Insurer and with prior notice to each Rating Agency,
enter into an indenture or indentures supplemental hereto for the purpose of
adding any provisions to, or changing in any manner or eliminating any of the
provisions of, this Indenture or of modifying in any manner the rights of the

The Issuer and the Indenture Trustee, when authorized by an Issuer Order, also

indenture pursuant to this Section, the Indenture Trustee shall mail to the
Holders of the Notes to which such amendment or supplemental indenture relates a
notice setting forth in general terms the substance of such supplemental

to Section 8.01(a) of the Sale and Servicing Agreement purchases the corpus of
the Trust, the Notes are subject to redemption in whole, but not in part, on the
Distribution Date on which such repurchase occurs, for a purchase price equal to
the Redemption Price; provided, however, that the Issuer has available funds
sufficient to pay the Redemption Price. The Seller, the Servicer or the Issuer
shall furnish the Insurer and each Rating Agency notice of such redemption. If
the Notes are to be redeemed pursuant to this Section 10.01, the Servicer or the
Issuer shall furnish notice of such election to the Indenture Trustee not later
than 20 days prior to the Redemption Date and the Issuer shall deposit with the
Indenture Trustee in the Note Distribution Account the Redemption Price of the
Notes to be redeemed whereupon all such Notes shall be due and payable on the
Redemption Date upon the furnishing of a notice complying with Section 10.02 to
each Holder of the Notes.

               Section 10.02 Form of Redemption Notice. Notice of redemption
under Section 10.01 shall be given by the Indenture Trustee by first-class mail,
postage prepaid, mailed not less than five days prior to the applicable
Redemption Date to each Holder of Notes, as of the close of business on the
Record Date preceding the applicable Redemption Date, at such Holder's address
appearing in the Note Register. In addition, the Administrator shall notify the
Insurer and Rating Agencies upon the redemption of any Class of Notes, pursuant
to Section 1(a)(i)(AA) of the Administration Agreement.

        All notices of redemption shall state:

                      (i)    the Redemption Date;


                                      -50-
<PAGE>   56

                      (ii)   the Redemption Price; and

                      (iii) the place where such Notes are to be surrendered for
               payment of the Redemption Price (which shall be the office or
               agency of the Issuer to be maintained as provided in Section
               3.02).

        Notice of redemption of the Notes shall be given by the Indenture
Trustee in the name and at the expense of the Issuer. Failure to give notice of
redemption, or any defect therein, to any Holder of any Note shall not impair or
affect the validity of the redemption of any other Note.

               Section 10.03 Notes Payable on Redemption Date. The Notes or
portions thereof to be redeemed shall, following notice of redemption (if any)
as required by Section 10.02, on the Redemption Date become due and payable at
the Redemption Price and (unless the Issuer shall default in the payment of the
Redemption Price) no interest shall accrue on the Redemption Price for any
period after the date to which accrued interest is calculated for purposes of
calculating the Redemption Price.

                               ARTICLE XI

                             MISCELLANEOUS

               Section 11.01 Compliance Certificates and Opinions, etc.

               (a) Upon any application or request by the Issuer to the
Indenture Trustee to take any action under any provision of this Indenture, the
Issuer shall furnish to the Indenture Trustee (i) an Officer's Certificate
stating that all conditions precedent, if any, provided for in this Indenture
relating to the proposed action have been complied with, (ii) an Opinion of
Counsel stating that in the opinion of such counsel all such conditions
precedent, if any, have been complied with and (iii) (if required by the TIA) an
Independent Certificate from a firm of certified public accountants meeting the
applicable requirements of this Section. Notwithstanding the foregoing, in the
case of any such application or request as to which the furnishing of such
documents is specifically required by any provision of this Indenture, no
additional certificate or opinion need be furnished.

        Every certificate or opinion with respect to compliance with a condition
or covenant provided for in this Indenture shall include:

                      (i) a statement that each signatory of such certificate or
               opinion has read or has caused to be read such covenant or
               condition and the definitions herein relating thereto;

                      (ii) a brief statement as to the nature and scope of the
               examination or investigation upon which the statements or
               opinions contained in such certificate or opinion are based;

                      (iii) a statement that, in the opinion of each such
               signatory, such signatory has made such examination or
               investigation as is necessary to enable


                                      -51-
<PAGE>   57

               such signatory to express an informed opinion as to whether or
               not such covenant or condition has been complied with; and

                      (iv) a statement as to whether, in the opinion of each
               such signatory, such condition or covenant has been complied
               with.

               (b) (i) Prior to the deposit of any Collateral or other property
or securities with the Indenture Trustee that is to be made the basis for the
release of any property subject to the lien created by this Indenture, the
Issuer shall, in addition to any obligation imposed in Section 11.01(a) or
elsewhere in this Indenture, furnish to the Indenture Trustee and the Insurer an
Officer's Certificate certifying or stating the opinion of the signer thereof as
to the fair value (within 90 days of such deposit) to the Issuer of the
Collateral or other property or securities to be so deposited.

               (ii) Whenever the Issuer is required to furnish to the Indenture
        Trustee and the Insurer an Officer's Certificate certifying or stating
        the opinion of any signer thereof as to the matters described in clause
        (i) above, the Issuer shall also deliver to the Indenture Trustee and
        the Insurer an Independent Certificate as to the named matters, if the
        fair value to the Issuer of the property to be so deposited and of all
        other such property made the basis of any such withdrawal or release
        since the commencement of the then-current fiscal year of the Issuer, as
        set forth in the Officer's Certificates delivered pursuant to clause (i)
        above and this clause (ii), is 10% or more of the Outstanding Amount of
        the Notes, but such Officer's Certificate need not be furnished with
        respect to any property so deposited, if the fair value thereof to the
        Issuer as set forth in the related Officer's Certificate is less than
        $25,000 or less than one percent of the Outstanding Amount of the Notes.

               (iii) Whenever any property or securities are to be released from
        the lien created by this Indenture, the Issuer shall also furnish to the
        Indenture Trustee and the Insurer an Officer's Certificate certifying or
        stating the opinion of each person signing such certificate as to the
        fair value (within 90 days of such release) of the property or
        securities proposed to be released and stating that in the opinion of
        such person the proposed release will not impair the security created by
        this Indenture in contravention of the provisions hereof.

               (iv) Whenever the Issuer is required to furnish to the Indenture
        Trustee and the Insurer an Officer's Certificate certifying or stating
        the opinion of any signer thereof as to the matters described in clause
        (iii) above, the Issuer shall also furnish to the Indenture Trustee and
        the Insurer an Independent Certificate as to the same matters if the
        fair value of the property or securities and of all other property or
        securities released from the lien created by this Indenture since the
        commencement of the then current fiscal year, as set forth in the
        Officer's Certificate required by clause (iii) above and this clause
        (iv), equals 10% or more of the Outstanding Amount of the Notes, but
        such Officer's Certificate need not be furnished in the case of any
        release of property or securities if the fair value thereof as set forth
        in the related Officer's Certificate is less than $25,000 or less than
        one percent of the then Outstanding Amount of the Notes.

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

        Any certificate or opinion of an Authorized Officer of the Issuer may be
based, insofar as it relates to legal matters, upon a certificate or opinion of,
or representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous. Any such certificate of an Authorized Officer or Opinion of Counsel
may be based, insofar as it relates to factual matters, upon a certificate or
opinion of, or representations by, an officer or officers of the Servicer, the
Seller or the Issuer, stating that the information with respect to such factual
matters is in the possession of the Servicer, the Seller or the Issuer, unless
such officer or counsel knows, or in the exercise of reasonable care should
know, that the certificate or opinion or representations with respect to such
matters are erroneous.

        Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

        Whenever in this Indenture, in connection with any application or
certificate or report to the Indenture Trustee, it is provided that the Issuer
shall deliver any document as a condition of the granting of such application,
or as evidence of the Issuer's compliance with any term hereof, it is intended
that the truth and accuracy, at the time of the granting of such application or
at the effective date of such certificate or report (as the case may be), of the
facts and opinions stated in such document shall in such case be conditions
precedent to the right of the Issuer to have such application granted or to the
sufficiency of such certificate or report. The foregoing shall not, however, be
construed to affect the Indenture Trustee's right to rely upon the truth and
accuracy of any statement or opinion contained in any such document as provided
in Article Six.

               Section  11.03   Acts of Noteholders.

               (a) Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by Noteholders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Noteholders in person or by agents
duly appointed in writing; and except as herein otherwise expressly provided,
such action shall become effective when such instrument or instruments are
delivered to the Indenture Trustee, and, where it is hereby expressly required,
to the Issuer. Such instrument or instruments (and the action embodied therein
and evidenced thereby) are herein sometimes referred to as the "Act" of the
Noteholders signing such instrument or instruments. Proof of execution of any
such instrument or of a writing appointing any such agent shall be sufficient
for any purpose of this Indenture and (subject to Section 6.01) conclusive in
favor of the Indenture Trustee and the Issuer, if made in the manner provided in
this Section.


                                      -53-
<PAGE>   59

               (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved in any manner that the Indenture Trustee
deems sufficient.

               (c) The ownership of Notes shall be proved by the Note Register.

               (d) Any request, demand, authorization, direction, notice,
consent, waiver or other action by the Holder of any Notes shall bind the Holder
of every Note issued upon the registration thereof or in exchange therefor or in
lieu thereof, in respect of anything done, omitted or suffered to be done by the
Indenture Trustee or the Issuer in reliance thereon, whether or not notation of
such action is made upon such Note.

               Section 11.04 Notices, etc., to Indenture Trustee, Issuer,
Insurer and Rating Agencies.

               (a) Any request, demand, authorization, direction, notice,
consent, waiver or Act of Noteholders or other documents provided or permitted
by this Indenture shall be in writing and if such request, demand,
authorization, direction, notice, consent, waiver or Act of Noteholders is to be
made upon, given or furnished to or filed with:

                      (i) the Indenture Trustee by any Noteholder or by the
               Issuer shall be sufficient for every purpose hereunder if in
               writing, personally delivered, sent by facsimile transmission and
               confirmed or mailed by overnight service, to or with the
               Indenture Trustee at its Corporate Trust Office;

                      (ii) the Issuer by the Indenture Trustee or by any
               Noteholder shall be sufficient for every purpose hereunder if in
               writing, personally delivered, sent by facsimile transmission and
               confirmed or mailed by overnight service, to the Issuer addressed
               to: Onyx Acceptance Owner Trust 2000-D, in care of Bankers Trust
               (Delaware), as Owner Trustee, 1011 Centre Road, Suite 200,
               Wilmington, Delaware 19805-1266, Attention: Corporate Trust
               Administration Department, or at any other address furnished in
               writing to the Indenture Trustee by the Issuer; or

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

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

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

        Where this Indenture provides for notice in any manner, such notice may
be waived in writing by any Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Noteholders shall be filed with the Indenture
Trustee but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such a waiver.

        In case, by reason of the suspension of regular mail service as a result
of a strike, work stoppage or similar activity, it shall be impractical to mail
notice of any event to Noteholders when such notice is required to be given
pursuant to any provision of this Indenture, then any manner of giving such
notice as shall be satisfactory to the Indenture Trustee shall be deemed to be a
sufficient giving of such notice.

        Where this Indenture provides for notice to the Rating Agencies, failure
to give such notice shall not affect any other rights or obligations created
hereunder, and shall not under any circumstance constitute a Default or Event of
Default.

               Section 11.06 Alternate Payment and Notice Provisions.
Notwithstanding any provision of this Indenture or any of the Notes to the
contrary, the Issuer may enter into any agreement with any Holder of a Note
providing for a method of payment, or notice by the Indenture Trustee or any
Paying Agent to such Holder, that is different from the methods provided for in
this Indenture for such payments or notices. The Issuer will furnish to the
Indenture Trustee a copy of each such agreement and the Indenture Trustee will
cause payments to be made and notices to be given in accordance with such
agreements.

               Section 11.07 Conflict With Trust Indenture Act. If any provision
hereof limits, qualifies or conflicts with another provision hereof that is
required to be included in this indenture by any of the provisions of the Trust
Indenture Act, such required provision shall control.

        The provisions of TIA Sections 310 through 317 that impose duties on any
Person (including the provisions automatically deemed included herein unless
expressly excluded by this Indenture) are a part of and govern this Indenture,
whether or not physically contained herein.

               Section 11.08 Effect of Headings and Table of Contents. The
Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.


                                      -55-

               Section 11.09 Successors and Assigns. All covenants and
agreements in this Indenture and the Notes by the Issuer shall bind its
successors and assigns, whether so expressed or not. All agreements of the
Indenture Trustee in this Indenture shall bind its successors, co- trustees and
agents.

               Section 11.10 Separability. In case any provision in this
Indenture or in the Notes shall be invalid, illegal or unenforceable, the
validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby.

               Section 11.11 Benefits of Indenture. The Insurer and its
successors and assigns shall be a third-party beneficiary to the provisions of
this Indenture, and shall be entitled to rely upon and directly to enforce such
provisions of this Indenture so long as no Insurer Default shall have occurred
and be continuing. Nothing in this Indenture or in the Notes, express or
implied, shall give to any Person, other than the parties hereto and their
successors hereunder, and the Noteholders, and any other party secured
hereunder, and any other Person with an ownership interest in any part of the
Collateral, any benefit or any legal or equitable right, remedy or claim under
this Indenture. The Insurer may disclaim any of its rights and powers under this
Indenture, but not its duties and obligations under the Policy, upon delivery of
a written notice to the Indenture Trustee.

               Section 11.12 Legal Holidays. In any case where the date on which
any payment is due shall not be a Business Day, then (notwithstanding any other
provision of the Notes or this Indenture) payment need not be made on such date,
but may be made on the next succeeding Business Day with the same force and
effect as if made on the date on which nominally due, and no interest shall
accrue for the period from and after any such nominal date.

               Section 11.13 Governing Law. THIS INDENTURE SHALL BE CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK AND THE OBLIGATIONS, RIGHTS,
AND REMEDIES OF THE PARTIES UNDER THIS INDENTURE SHALL BE DETERMINED IN
ACCORDANCE WITH SUCH LAWS.

               Section 11.14 Counterparts. This Indenture may be executed in
several counterparts, each of which shall be an original and all of which shall
constitute but one and the same instrument.

               Section 11.15 Recording of Indenture. If this Indenture is
subject to recording in any appropriate public recording offices, such recording
is to be effected by the Issuer and at its expense accompanied by an Opinion of
Counsel (which may be counsel to the Indenture Trustee or any other counsel
reasonably acceptable to the Indenture Trustee and the Insurer) to the effect
that such recording is necessary either for the protection of the Noteholders or
any other Person secured hereunder or for the enforcement of any right or remedy
granted to the Indenture Trustee under this Indenture.

               Section 11.16 Trust Obligation. No recourse may be taken,
directly or indirectly, with respect to the obligations of the Issuer, the Owner
Trustee or the Indenture Trustee on the Notes or under this Indenture or any
certificate or other writing delivered in connection herewith or therewith,
against (i) the Indenture Trustee or the Owner Trustee in its individual
capacity, (ii) any owner of a beneficial interest in the Issuer or (iii) any
partner, owner,


                                      -56-
<PAGE>   62

beneficiary, agent, officer, director, employee or agent of the Indenture
Trustee or the Owner Trustee in its individual capacity, any Holder of a
beneficial interest in the Issuer, the Owner Trustee or the Indenture Trustee or
of any successor or assign of the Indenture Trustee or the Owner Trustee in its
individual capacity, except as any such Person may have expressly agreed (it
being understood that the Indenture Trustee and the Owner Trustee have no such
obligations in their individual capacity) and except that any such partner,
owner or beneficiary shall be fully liable, to the extent provided by applicable
law, for any unpaid consideration for stock, unpaid capital contribution or
failure to pay any installment or call owing to such entity. For all purposes of
this Indenture, in the performance of any duties or obligations of the Issuer
hereunder, the Owner Trustee shall be subject to, and entitled to the benefits
of, the terms and provisions of Articles Six, Seven and Eight of the Trust
Agreement.

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

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

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

               Section 11.20 Certain Matters Regarding the Insurer. So long as
an Insurer Default shall not have occurred and be continuing, the Insurer shall
have the right to exercise all rights, including voting rights, which the
Noteholders or Residual Interestholders are entitled to


                                      -57-
<PAGE>   63

exercise pursuant to this Indenture, without any consent of such Noteholders or
Residual Interestholders; provided, however, that without the consent of each
Noteholder or Residual Interestholder affected thereby, the Insurer shall not
exercise such rights to amend this Indenture in any manner that would (i) reduce
the amount of, or delay the timing of, collections of payments on the Contracts
or distributions which are required to be made on any Note or Residual Interest
Instrument, (ii) adversely affect in any material respect the interests of the
Holders of any Notes or Residual Interest Instruments, or (iii) alter the rights
of any such Holder to consent to such amendment.

        Notwithstanding any provision in this Indenture to the contrary, in the
event an Insurer Default shall have occurred and be continuing, the Insurer
shall not have the right to take any action under this Agreement or to control
or direct the actions of the Trust, the Seller, the Indenture Trustee, the Owner
Trustee or the Trust Agent pursuant to the terms of this Indenture, nor shall
the consent of the Insurer be required with respect to any action (or waiver of
a right to take action) to be taken by the Trust, the Seller, the Indenture
