<PAGE>   13

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) $72,000,000 of Class A-1 Notes, (ii) $132,000,000 of Class
A-2 Notes, (iii) $107,000,000 of Class A-3 Notes and (iv) $93,200,000 of Class

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 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

                                      -8-
<PAGE>   14

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 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

                                      -9-
<PAGE>   15

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 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,

their respective agents shall be affected by notice to the contrary.

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

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

                (i) the Final Scheduled Distribution Date of such 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

            continuing and if an Insurer Default has occurred and is continuing,

        representing not less than 66 2/3% of the Outstanding Amount 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

and principal of each Class of Notes, and upon the termination of the Trust, in
each case pursuant to the Administration Agreement.

            Section 2.08 Cancellation. All Notes surrendered for payment,

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.

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,
and no Note Owner will receive a Definitive Note representing such Note Owner's
interest in such Note, except as provided in Section 2.11. Unless and until
definitive, fully registered Notes (the "DEFINITIVE NOTES") have been issued to
Note Owners pursuant to Section 2.11:

            effect;

                (ii) the Note Registrar and the Indenture Trustee shall be
            entitled to deal with the Clearing Agency for all purposes of this
            Indenture (including the payment of principal of and 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;

                                      -12-
<PAGE>   18

                (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;

                (iv) the rights of Note Owners shall be exercised only 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 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

                                      -13-

(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.

                                   ARTICLE III

                                    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
all amounts on deposit in the Note Distribution Account on a Distribution Date
deposited therein pursuant to the Sale and Servicing Agreement for the benefit
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.
Amounts properly withheld under the Code by any Person from a payment to any
Noteholder of interest and/or principal shall be considered as having been paid
by the Issuer to such Noteholder for all purposes of this Indenture.

            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

                                      -14-
<PAGE>   20

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;

               (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

                                      -15-
<PAGE>   21

        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.

            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

                                      -16-
<PAGE>   22

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 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

                                      -17-
<PAGE>   23

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, the Noteholders or the
Certificateholders pursuant to Section 7.01 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 Certificates evidencing not
less than 51% of the outstanding principal amount of the Certificates, shall
appoint a Successor Servicer. The Successor Servicer shall

                                      -18-
<PAGE>   24

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;

               (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

                                      -19-
<PAGE>   25

        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 hereto, executed and delivered to
        the Indenture Trustee and the Insurer, in form and substance
        satisfactory to the Indenture Trustee and the Insurer (so long as no
        Insurer Default shall have occurred and be continuing), the due and
        punctual payment of the principal of and interest on all Notes and the
        performance or observance of every agreement and covenant of this
        Indenture and each other Basic Document on the part of the Issuer to be
        performed or observed, all as provided herein;

               (ii) immediately after giving effect to such consolidation or
        merger, no Default or Event of Default shall have occurred and be
        continuing;

               (iii) the Rating Agency Condition shall have been satisfied with
        respect to such consolidation or merger;

               (iv) the Issuer shall have received an Opinion of Counsel which
        shall be delivered to and shall be satisfactory to the Indenture Trustee
        and the Insurer to

                                      -20-
<PAGE>   26

        the effect that such consolidation or merger will not have any material
        adverse tax consequence to the Trust, the Insurer, any Noteholder or any
        Certificateholder;

               (v) any action as is necessary to maintain the lien and security
        interest created by this Indenture shall have been taken;


               (vi) the Issuer shall have delivered to the Indenture Trustee and
        the Insurer an Officer's Certificate and an Opinion of Counsel (which
        shall describe the actions taken as required by clause (v) above or that
        no such actions will be taken) each stating that such consolidation or
        merger and such supplemental indenture comply with this Article Three
        and that all conditions precedent herein provided for relating to such
        transaction have been compiled with (including any filings required by
        the Exchange Act); and

               (vii) so long as no Insurer Default shall have occurred and be
        continuing, the Issuer shall have given the Insurer written notice of
        such consolidation or merger at least 20 Business Days prior to the
        consummation of such action and shall have received the prior written
        approval of the Insurer of such consolidation or merger and the Issuer
        or the Person (if other than the Issuer) formed by or surviving such
        consolidation or merger has a net worth, immediately after such
        consolidation or merger, that is (A) greater than zero and (B) not less
        than the net worth of the Issuer immediately prior to giving effect to
        such consolidation or merger.

            (b) The Issuer shall not convey or transfer all or substantially all
of its properties or assets, including those included in the Collateral, to any
Person (except as expressly permitted by the Basic Documents), unless:

               (i) the Person that acquires by conveyance or transfer the
        properties and assets of the Issuer shall (A) be a United States citizen
        or a Person organized and existing under the laws of the United States
        or any State, (B) expressly assume, by an indenture supplemental hereto,
        executed and delivered to the Indenture Trustee and the Insurer, in form
        and substance satisfactory to the Indenture Trustee and the Insurer (so
        long as no Insurer Default shall have occurred and be continuing), the
        due and punctual payment of the principal of and interest on all Notes
        and the performance or observance of every agreement and covenant of
        this Indenture and each other Basic Document on the part of the Issuer
        to be performed or observed, all as provided herein, (C) expressly agree
        by means of such supplemental indenture that all right, title and
        interest so conveyed or transferred shall be subject and subordinate to
        the rights of Holders of the Notes, (D) unless otherwise provided in
        such supplemental indenture, expressly agree to indemnify, defend and
        hold harmless the Issuer against and from any loss, liability or expense

                           EVENTS OF DEFAULT; REMEDIES

            Section 5.01 Events of Default. "EVENT OF DEFAULT," wherever used
herein, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):

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

            (b) default in the payment of any interest on any Note when the same
becomes due and payable, and such default shall continue for a period of five
days;

            (c) default in the payment of any principal due and payable on a
Class of Notes on the 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
agreement, a default in the

                                      -25-
<PAGE>   31

observance or performance of which is elsewhere in 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 any certificate delivered
pursuant hereto or in connection herewith having been incorrect in a material
respect as of the time made, and such breach not having 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
days; or

            (f) the commencement by the Issuer of a voluntary case under any
applicable federal or state bankruptcy, insolvency or other similar law now or
hereafter in effect, or the consent by the Issuer to the entry of an order for
relief in an involuntary case under any such law, or the consent by the Issuer
to the appointment or taking possession by a receiver, liquidator, assignee,
custodian, trustee, sequestrator or similar official of the Issuer or for any
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 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.

            Section 5.02 Rights Upon Event of Default.

            (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

                                      -26-
<PAGE>   32

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 and the Certificates.

            (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 the Holders of Notes representing at least
66 2/3% of the aggregate Outstanding Amount of the Notes, 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 the Holders of Notes
representing at least 66 2/3% of the Outstanding Amount of the Notes, 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

                                      -27-
<PAGE>   33

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 (including any claim
        for reasonable compensation to the Indenture Trustee and each
        predecessor 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

                                      -28-
<PAGE>   34

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

        the Notes;

               (iv) sell or cause the Servicer to otherwise liquidate the

                                      -29-
<PAGE>   35

        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 the Holders of Notes representing at least 66 2/3% of the
        Outstanding Amount of the Notes, 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) either (x) the proceeds of such sale or liquidation
        would be sufficient to pay all outstanding principal of and accrued
        interest on the Notes and the Certificates and all amounts owing to the
        Insurer pursuant to the terms of the Insurance Agreement or (y) the
        Holders of Certificates evidencing 100% of the outstanding principal
        amount of the Certificates consent to such liquidation and all amounts
        owing to the Insurer under the Insurance Agreement shall be paid upon
        such sale or liquidation. In the event of a liquidation of the
        Collateral pursuant to clause (B), the Policy will not be available to
        cover losses to Securityholders 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, the Notes or the
Certificates 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, the Notes or the Certificates (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 Noteholders, to pay accrued interest on each Class
        of 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 Notes at the
        related Interest Rate for such Class;

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

               fifth, to the Certificateholders, to pay accrued interest on the
        Certificates (including, to the extent permitted by applicable law,
        interest accrued on any interest accrued but not timely paid) at the
        Certificate Rate;

               sixth, to the Certificateholders, to pay principal on the
        Certificates until the Certificate Balance is reduced to zero;

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

               eighth, any excess amounts remaining after making the
        distributions described in clauses first through seventh 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:

                                      -31-
<PAGE>   37

               (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 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;

               (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, voting 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

                                      -32-
<PAGE>   38

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 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 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

                                      -33-
<PAGE>   39

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.

            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

                                      -34-
<PAGE>   40

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,

                                      -35-
<PAGE>   41

        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:

               (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

                                      -36-
<PAGE>   42

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, relating to the time, method and
place of conducting any proceeding 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.

                                      -37-
<PAGE>   43

            (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 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.

            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

                                      -39-
<PAGE>   45

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 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.

                                      -40-
<PAGE>   46

        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.

        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

                                      -41-
<PAGE>   47

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:

                (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
or co-trustee shall die, become incapable of acting, resign or be removed, all
of its estates, properties, rights, remedies and trusts shall vest in and be
exercised by the Indenture Trustee, to the extent permitted by law, without the
appointment of a new or successor trustee. Notwithstanding anything to the
contrary in this Indenture, the appointment of any separate trustee or
co-trustee shall not relieve the Indenture Trustee of its obligations and duties
under this Indenture.

            Section 6.11 Eligibility; Disqualification.

            (a) The Indenture Trustee shall have a combined capital and surplus
of at least $50,000,000 as set forth in its most recent published annual report
of condition. The Indenture

                                      -42-
<PAGE>   48

Trustee shall provide copies of such reports to the Insurer upon request. The
Indenture Trustee shall comply with TIA Section 310(b); provided, however, that
there shall be excluded from the operation of TIA Section 310(b)(1) any
indenture or indentures under which other securities of the Issuer are
outstanding if the requirements for such exclusion set forth in TIA Section
310(b)(1) are met.

            (b) If the long term debt rating of the Indenture Trustee shall not
be at least Baa3 from Moody's and BBB- from Standard & Poor's, the Rating
Agencies shall be given notice of such lower long-term debt rating.

            Section 6.12 Preferential Collection of Claims Against Issuer. The
Indenture Trustee shall comply with TIA Section 311(a), excluding any creditor
relationship listed in TIA Section 311(b). An Indenture Trustee who has resigned
or been removed shall be subject to Section 311(a) to the extent indicated.

            Section 6.13 Representations and Warranties of Indenture Trustee.
The Indenture Trustee hereby makes the following representations and warranties
on which the Issuer and Noteholders shall rely:

            (a) the Indenture Trustee is a corporation duly organized, validly
existing and in good standing under the laws of its place of incorporation; and

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

            Section 8.01 Collection of Money.

            (a) General. Except as otherwise expressly provided herein, the
Indenture Trustee may demand payment or delivery of, and shall receive and
collect, directly and without intervention or assistance of any fiscal agent or
other intermediary, all money and other property payable to or receivable by the
Indenture Trustee pursuant to this Indenture. The Indenture Trustee shall apply
all such money received by it as provided in this Indenture. Except as otherwise
expressly provided in this Indenture, if any default occurs in the making of any
payment or performance under any agreement or instrument that is part of the
Collateral, the Indenture Trustee may take such action as may be appropriate to
enforce such payment or performance, including the institution and prosecution
of appropriate Proceedings. Any such action shall be without prejudice to any
right to claim a Default or Event of Default under this Indenture and any right
to proceed thereafter as provided in Article Five.

            (b) Claims Under Policy. The Notes and the Certificates will be
insured by the Policy pursuant to the terms set forth therein, notwithstanding
any provisions to the contrary contained in this Indenture or the Sale and
Servicing Agreement. All amounts received under the Policy shall be used solely

Amount, to make the deposits to the Note Distribution Account required pursuant

            Principal Distributable Amount (after giving effect to the payment,
            if any, described in clause (ii) above), until the Outstanding
            Amount of the Class A-1 Notes is reduced to zero;

                (iv) to the Holders of the Class A-2 Notes, the remaining Note
            Principal Distributable Amount (after giving effect to the payments,
            if any, described in clauses (ii) and (iii) above), until the
            Outstanding Amount of the Class A-2 Notes is reduced to zero;

                (v) to the Holders of the Class A-3 Notes, the remaining Note
            Principal Distributable Amount (after giving effect to the payments,

pursuant to Section 4.02(c) of the Sale and Servicing Agreement and in
accordance with the Policy. In making any such claim, the Indenture Trustee
shall comply with all the terms and conditions of the Policy. Upon receipt of

Claim Amount as part of the Note Distributable Amount under this Indenture to
the extent such Policy Claim Amount relates to the Notes and as part of the
Certificate Distributable Amount under the Sale and Servicing Agreement to the
extent such Policy Claim Amount relates to the Certificates.

            Section 8.04 Release of Collateral.

            (a) Subject to the payment of its fees and expenses pursuant to
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,

                                      -46-

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 Request accompanied by an Officer's
Certificate, an Opinion of Counsel and (if required by the TIA) Independent
Certificates in accordance with TIA Sections 314(c) and 314(d)(1) meeting the
applicable requirements of Section 11.01.

            Section 8.05 Opinion of Counsel. The Indenture Trustee shall receive
at least seven days' notice when requested by the Issuer to take any action
pursuant to Section 8.04(a), accompanied by copies of any instruments 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 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.

            or required to be subjected to the lien created by this Indenture,
            or to subject to the lien created by this Indenture additional

            herein and in the Notes contained;

                (iii) to add to the covenants of the Issuer, for the benefit of
            the Holders of the Notes, or to surrender any right or power herein

            inconsistent with any other provision herein or in any supplemental
            indenture or the Basic Documents or to make any other provisions
            with respect to matters or questions arising under this Indenture or
            in any supplemental indenture; provided that such action shall not
            adversely affect the interests of the Holders of the Notes;

                (vi) to evidence and provide for the acceptance of the
            appointment hereunder by a successor trustee with respect to the
            Notes and to add to or change any of the provisions of this
            Indenture as shall be necessary to facilitate the administration of
            the trusts hereunder by more than one trustee, pursuant to the
            requirements of Article Six; or

                (vii) to modify, eliminate or add to the provisions of this
            Indenture to such extent as shall be necessary to effect the
            qualification of this Indenture under the TIA or under any similar
            federal statute hereafter enacted and to add to this Indenture such
            other provisions as may he expressly required by the TIA.

        The Indenture Trustee is hereby authorized to join in the execution of
any such supplemental indenture and to make any further appropriate agreements
and stipulations that may be therein contained.

            (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
Holders of the Notes under this Indenture; provided, however, that such action
shall not, as evidenced by an Opinion of Counsel, adversely affect in any
material respect the interests of any Noteholder.

            Section 9.02 Supplemental Indentures With Consent of Noteholders.
The Issuer and the Indenture Trustee, when authorized by an Issuer Order, also
may, with prior notice to each Rating Agency, with the consent of the Insurer
and with the consent of the Holders of not less than 51% of the Outstanding
Amount of the Notes, by Act of such Holders delivered to the Issuer and the
Indenture Trustee, 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 Holders of the Notes under this Indenture; provided,
however, that, subject to the express rights of the Insurer under the Basic
Documents, no such supplemental indenture shall, without the consent of the
Holder of each Outstanding Note affected thereby:

            (a) change the date of payment of any installment of principal of or
interest on any Note, or reduce the principal amount thereof, the interest rate
thereon or the Redemption

                                      -48-

            (b) impair the right to institute suit for the enforcement of the
provisions of this Indenture requiring the application of funds available

the Notes on or after the respective due dates thereof (or, in the case of
redemption, on or after the Redemption Date);

            (c) reduce the percentage of the Outstanding Amount of the Notes,
the consent of the Holders of which is required for any such supplemental
indenture, or the consent of the Holders of which is required for any waiver of
compliance with certain provisions of this Indenture or certain defaults
hereunder and their consequences provided for in this Indenture;

            (d) modify or alter the provisions of the second proviso to the
definition of the term "Outstanding";

deprive the Holder of any Note of the security provided by the lien created by
this Indenture.

        The Indenture Trustee may in its discretion determine whether or not any
Notes would be affected by any supplemental indenture and any such determination
shall be conclusive upon the Holders of all Notes, whether theretofore or
thereafter authenticated and delivered hereunder. The Indenture Trustee shall
not be liable for any such determination made in good faith.

        It shall not be necessary for any act of Noteholders under this Section
to approve the particular form of any proposed supplemental indenture, but it
shall be sufficient if such act shall approve the substance thereof.

        Promptly after the execution by the parties hereto of any supplemental
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
indenture. Any failure of the Indenture Trustee to mail such notice, or any
defect therein, shall not, however, in any way impair or affect the validity of
any such supplemental indenture.

            Section 9.03 Execution of Supplemental Indentures. In executing, or
permitting the additional trusts created by, any supplemental indenture
permitted by this Article or the modifications thereby of the trusts created by
this Indenture, the Indenture Trustee shall be

                                      -49-
<PAGE>   55

entitled to receive, and subject to Sections 6.01 and 6.02 shall be fully
protected in relying upon, an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture. The
Indenture Trustee may, but shall not be obligated to, enter into any such
supplemental indenture that affects the Indenture Trustee's own rights, duties,
liabilities or immunities under this Indenture or otherwise.

            Section 9.04 Effect of Supplemental Indenture. Upon the execution of
any supplemental indenture pursuant to the provisions hereof, this Indenture
shall be and be deemed to be modified and amended in accordance therewith with
respect to the Notes affected thereby, and the respective rights, limitations of
rights, obligations, duties, liabilities and immunities under this Indenture of
the parties hereto and the Holders of the Notes shall thereafter be determined,
exercised and enforced hereunder subject in all respects to such modifications
and amendments, and all the terms and conditions of any such supplemental
indenture shall be and be deemed to be part of the terms and conditions of this
Indenture for any and all purposes.

            Section 9.05 Conformity With Trust Indenture Act. Every amendment of
this Indenture and every supplemental indenture executed pursuant to this
Article shall conform to the requirements of the Trust Indenture Act as then in
effect so long as this Indenture shall then be qualified under the Trust
Indenture Act.

            Section 9.06 Reference in Notes to Supplemental Indentures. Notes
authenticated and delivered after the execution of any supplemental indenture
pursuant to this Article may, and if required by the Indenture Trustee shall,
bear a notation in form approved by the Indenture Trustee as to any matter
provided for in such supplemental indenture. If the Issuer or the Indenture
Trustee shall so determine, new notes so modified as to conform, in the opinion
of the Indenture Trustee and the Issuer, to any such supplemental indenture may
be prepared and executed by the Issuer and authenticated and delivered by the
Indenture Trustee in exchange for Outstanding Notes.

                               REDEMPTION OF NOTES


            Section 10.01 Redemption. In the event that the Servicer pursuant 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

            Section 10.02 Form of Redemption Notice. Notice of redemption under

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;

                (ii) the Redemption Price; and

                (iii) the place where such Notes are to be surrendered for

        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.

all conditions precedent, if any, provided for in this Indenture relating to the

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.

                                      -51-
<PAGE>   57

        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

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

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

        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

        fair value (within 90 days of such release) of the property or

               (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

        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.

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.

            (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

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,

            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
Floor), New York, New York 10041, Attention: Asset Backed Surveillance
Department; or as to each of the foregoing, at such other address as shall be
designated by written notice to the other parties.

            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.

            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,
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

                                      -57-
<PAGE>   63

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, Certificateholders or Residual Interestholders are entitled to
exercise pursuant to this Indenture, without any consent of such Noteholders,
Certificateholders or Residual Interestholders; provided, however, that without
the consent of each Noteholder, Certificateholder 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, Certificate or Residual Interest Instrument, (ii)
adversely affect in any material respect the interests of the Holders of any
Notes, Certificates 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
Trustee, the Owner Trustee, the Trust Agent or the Holders of the Notes, the
Certificates, or the Residual Interest Instruments; provided, that the consent
of the Insurer shall be required at all times with respect to any amendment of
this Indenture.
