evidenced by their execution of such Notes.

     Each Note shall be dated the date of its authentication.  The terms of the
Notes 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 any of its Authorized Officers. 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

     The Indenture Trustee shall, upon Issuer Order, authenticate and deliver
for original issue the following aggregate principal amounts of Notes: (i)

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 initially shall be the registrar (the "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, provided that
the requirements of Section 8-401 of the UCC are met, the Issuer shall execute,
and the Indenture Trustee shall authenticate and deliver to the Noteholder
making such surrender 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 denomination and a like aggregate
principal amount.

     At the option of the related 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, provided that the
requirements of Section 8-401 of the UCC are met (as determined by the Issuer),
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.

<PAGE>

     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 an "eligible guarantor institution" meeting the
requirements of the Note Registrar.

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

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

     Each Person to whom a Note is transferred will be required to represent, in
the case of a Definitive Note, or deemed to represent, in the case of a Book-
Entry Note, that (i) such Person is not an employee benefit plan, as described
in Section 3(3) of ERISA, or a plan, as defined in Section 4975(E)(1) of the
Code, that is subject to Title I of ERISA or to Section 4975 of the Code, a
government plan subject to any state or local law similar to Title I of ERISA or
Section 4975 of the Code, or a Person investing on behalf of or with "plan
assets" of such a plan, or (ii) the Person's acquisition, holding and
disposition of the Note are and will be eligible for relief under a prohibited
transaction exemption.

     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, (ii) there is delivered to the Indenture Trustee and, so long as no
Insurer Default shall have occurred and be continuing, the Insurer such security
or indemnity as may be required by it to hold the Issuer, the Insurer and the
Indenture Trustee harmless and (iii) the requirements of Section 8-405 of the
UCC are met, then, in the absence of notice to the Issuer, the Note Registrar or
the Indenture Trustee that such Note has been acquired by a Protected 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 Protected Purchaser of the original
Note in lieu of which such replacement Note was issued presents for payment such
original Note, the Insurer, the Issuer and the

                                      13
<PAGE>

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 Protected 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
                    --------------------

Trustee 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,

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

     Section 2.09.  Book-Entry Notes.  The Notes, upon original issuance, will
                    ----------------
be issued in the form of a typewritten Note or Notes representing the Book-Entry
Notes, to be delivered to The Depository Trust Company, the initial Clearing
Agency, by, or on behalf of, the Issuer. The Book-Entry Notes shall be
registered initially 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 such Note Owners pursuant to Section
2.11:

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

            (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 Note 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 Note Balance, 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 such 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 such Note Owners.

     Section 2.11.  Definitive Notes.  If (i)(a) the Administrator advises the
                    ----------------
Indenture Trustee in writing that the Clearing Agency is no longer willing or
able to properly discharge its responsibilities with respect to the Book-Entry
Notes and (b) neither the Indenture Trustee nor the Administrator is able to
locate a qualified successor, (ii) the Administrator at its option advises the
Indenture Trustee in writing that it elects to terminate the book-entry system
through the Clearing Agency or (iii) after the occurrence of an Event of Default
or a Master Servicer Termination Event, Owners of Book-Entry Notes representing
beneficial interests aggregating not less than 51% of the principal amount of
such Notes advise the Indenture Trustee and the Clearing Agency Participants
through the Clearing Agency, in writing that the continuation of a book-entry
system through the Clearing Agency is no longer in the best interests of such
Note Owners, then, in each case, the Indenture Trustee shall notify all Note
Owners of the related Class of Notes through the Clearing Agency of the
occurrence of any such event and of the availability of Definitive Notes of the
related Class of Notes to Note Owners requesting the same. Upon surrender to the
Indenture Trustee of the Note or Notes representing the Book-Entry Notes by the
Clearing Agency, accompanied by registration instructions, the Issuer shall
execute and the Indenture Trustee shall authenticate the 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.

     Section 2.12.  Release of Collateral.  Subject to Section 11.01 and the
                    ---------------------
terms of the other 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)(1) 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 all purposes
including federal, state and local income, single business and franchise tax
purposes, the Notes will qualify as indebtedness of the Issuer secured by the
Trust Estate. The Issuer, by entering into this Indenture, and each Noteholder,
by its acceptance of a Note (and each Note Owner by its acceptance of an
interest in the applicable Book-Entry Note), agree to treat the Notes for all
purposes including federal, state and local income, single business and
franchise tax purposes as indebtedness of the Issuer.

     Section 2.14.  Employee Benefit Plans.  A fiduciary of a Benefit Plan
                    ----------------------
purchasing the Notes with the assets of a Benefit Plan is deemed to represent
that the purchase of one or more Notes is consistent with its fiduciary duties
under ERISA and does not result in a nonexempt prohibited transaction as defined
in Section 406 of ERISA or Section 4975 of the Code. If the

                                      19
<PAGE>

Depositor, the Seller, the Master Servicer, the Indenture Trustee, the Owner
Trustee or any of their respective Affiliates (i) has investment or
administrative discretion with respect to the assets of a Benefit Plan; (ii) has
authority or responsibility to give, or regularly gives, investment advice with
respect to such Benefit Plan assets, for a fee and pursuant to an agreement or
understanding that such advice (a) will serve as a primary basis for investment
decisions with respect to such Benefit Plan assets and (b) will be based on the
particular investment needs for such Benefit Plan; or (iii) is an employer
maintaining or contributing to such Benefit Plan, then a purchase of the Notes
by such a Benefit Plan may represent a conflict of interest or act of self-
dealing by the fiduciary.

     Section 2.15.  Authenticating Agents.  The Indenture Trustee may appoint
                    ---------------------
one or more Persons (each, an "Authenticating Agent") with power to act on its
behalf and subject to its direction in the authentication of Notes in connection
with issuance, transfers and exchanges under Sections 2.02, 2.03, 2.04 and 2.05,
as fully to all intents and purposes as though each such Authenticating Agent
had been expressly authorized by those Sections to authenticate such Notes. For
all purposes of this Indenture, the authentication of Notes by an Authenticating
Agent pursuant to this Section shall be deemed to be the authentication of Notes
"by the Indenture Trustee."

     Any corporation into which any Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, consolidation or conversion to which any Authenticating Agent
shall be a party, or any corporation succeeding to all or substantially all of
the corporate trust business of any Authenticating Agent, shall be the successor
of such Authenticating Agent hereunder, without the execution or filing of any
document or any further act on the part of the parties hereto or such
Authenticating Agent or such successor corporation.

     Any Authenticating Agent may at any time resign by giving written notice of
resignation to the Indenture Trustee and the Owner Trustee. The Indenture
Trustee may at any time terminate the agency of any Authenticating Agent by
giving written notice of termination to such Authenticating Agent and the Owner
Trustee. Upon receiving such notice of resignation or upon such a termination,
the Indenture Trustee may appoint a successor Authenticating Agent and shall
give written notice of any such appointment to the Owner Trustee.

     The Administrator agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services. The provisions of Sections 2.08
and 6.04 shall be applicable to any Authenticating Agent.

                                   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(b), the Issuer will cause to be distributed
all amounts on deposit in the Note Distribution Account on a Distribution Date
deposited therein in accordance with Section 8.02(c). 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 maintain
                    -------------------------------
in the Borough of Manhattan, 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 Depositor and the Indenture Trustee of the
location, and of any change in the location, of any such office or agency. If at
any time the Issuer shall fail to maintain any such office or agency or shall
fail to furnish the Indenture Trustee with the address thereof, such surrenders,
notices and demands may be made or served at the Corporate Trust Office, and the
Issuer hereby appoints the Indenture Trustee as its agent to receive all such
surrenders, notices and demands on behalf of the Issuer.

     Section 3.03.  Money for Payments to be Held in Trust.  As provided in
                    --------------------------------------
Sections 5.04 and 8.02, all payments of amounts due and payable with respect to
any Notes that are to be made from amounts withdrawn from the Collection Account
and the Note Distribution Account pursuant to Section 8.02(c) shall be made on
behalf of the Issuer by the Indenture Trustee or by another Paying Agent, and no
amounts so withdrawn from the Collection Account and the Note Distribution
Account for payments of Notes shall be paid over to the Issuer except as
provided in this Section.

     On or before each Distribution Date and Redemption Date, the Issuer shall
deposit or cause to be deposited in the Note Distribution Account an aggregate
sum sufficient to pay the amounts then becoming due under the Notes, such sum to
be held in trust for the benefit of the Persons entitled thereto, and (unless
the Paying Agent is the Indenture Trustee) shall promptly notify the Indenture
Trustee in writing of its action or failure so to act.

     The Issuer will cause each Paying Agent other than the Indenture Trustee to
execute and deliver to the Indenture Trustee and to 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

                                      21
<PAGE>

     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) of which it has actual knowledge 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 a Paying Agent and forthwith pay to the
     Indenture Trustee all sums held by it in trust for the payment of Notes if
     at any time it ceases to meet the standards required to be met by a Paying
     Agent at the time of its appointment; and

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

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

     Subject to applicable laws with respect to escheat of funds, any money held
by the Indenture Trustee or any Paying Agent in trust for the payment of any
amount due with respect to any Note and remaining unclaimed for two years after
such amount has become due and payable shall be discharged from such trust and
be paid to the Issuer on Issuer Request with, so long as no Insurer Default
shall have occurred and be continuing, the consent of the Insurer; and the
Holder of such Note shall thereafter, as an unsecured general creditor, look
only to the Issuer for payment thereof (but only to the extent of the amounts so
paid to the Issuer), and all liability of the Indenture Trustee or such Paying
Agent with respect to such trust money shall thereupon cease; provided, however,
that if such money or any portion thereof had been previously deposited by the
Insurer with the Indenture Trustee for the payment of principal or interest on
the Notes, to the extent any amounts are owing to the Insurer, such amounts
shall be paid promptly to the Insurer upon receipt of a written request by the
Insurer to such effect; and provided, further, that the Indenture Trustee or
such Paying Agent, before being required to make any such repayment, shall at
the expense and written 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 shall also adopt and employ, at the expense and

                                      22
<PAGE>

written direction of the Issuer, any other reasonable means of notification of
such repayment (including 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, the Collateral and each other instrument or agreement
included in the Trust Estate, including all licenses required under the
Pennsylvania Motor Vehicle Sales Finance Act in connection with this Indenture
and the other Basic Documents and the transactions contemplated hereby and
thereby until such time as the Issuer shall terminate in accordance with the
terms hereof.

     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 Insurer and the Noteholders to be prior to all other liens in
respect of the Trust Estate, and the Issuer shall take all actions necessary to
obtain and maintain, for the benefit of the Indenture Trustee on behalf of the
Insurer and the Noteholders, a first lien on and a first priority, perfected
security interest in the Trust Estate, subject to the rights of the Insurer
under the Insurance Agreement. The Issuer will from time to time execute and
deliver all such supplements and amendments hereto and all such financing
statements, continuation statements, instruments of further assurance and other
instruments, all as prepared by the Administrator and delivered to the Issuer,
and will take such other action necessary or advisable to:

            (i)    Grant more effectively any portion of the Trust Estate;

            (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 Trust Estate and the rights
     of the Indenture Trustee and the Noteholders in such Trust Estate against
     the claims of all persons and parties; or

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

     Section 3.06.  Opinions as to Trust Estate.
                    ---------------------------

     (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 Insurer and 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 fiscal year of the Issuer
beginning with the first fiscal year beginning more than three months after the
Cutoff Date, the Issuer shall furnish to the Depositor and 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 Insurer and the
Noteholders, and reciting the details of such filings or referring to prior
Opinions of Counsel in which such details are given, or (ii) no such action
shall be necessary to perfect such security interest.

     Section 3.07.  Performance of Obligations; Servicing of Receivables.
                    ----------------------------------------------------

     (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 Trust Estate 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 this Indenture, the other Basic Documents or such other
instrument or agreement.

     (b) The Issuer may contract with other Persons to assist it in performing
its duties under this Indenture, and any performance of such duties by a Person
identified to the Indenture Trustee and to the Insurer in an Officer's
Certificate of the Issuer shall be deemed to be action taken by the Issuer.
Initially, the Issuer has contracted with the Master Servicer and the
Administrator to assist the Issuer in performing its duties under this
Indenture.

     (c) The Issuer will and will cause the Administrator to, 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
Trust Estate, including 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 other Basic Documents in accordance with and within the time
periods provided for herein and therein.

     (d) If the Issuer shall have knowledge of the occurrence of a Trigger
Event, a Subservicer Trigger Event, a Master Servicer Termination Event or a
Subservicer Termination Event, the Issuer shall promptly provide written notice
to an Executive Officer of the Depositor

                                      24
<PAGE>

and the Insurer and a Responsible Officer of the Indenture Trustee, and to 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 Trigger Event, a Subservicer
Trigger Event, a Master Servicer Termination Event or a Subservicer Termination
Event shall arise from the failure of the Master Servicer or the Subservicer, as
the case may be, to perform any of its duties or obligations under the Sale and
Servicing Agreement with respect to the Receivables, the Issuer shall take all
reasonable steps available to it to remedy such failure.

     (e)  As promptly as possible after giving the Master Servicer a Master
Servicer Termination Notice or the Subservicer a Subservicer Termination Notice
pursuant to Section 7.01 or 7.02 of the Sale and Servicing Agreement, as the
case may be, the Issuer shall (subject to the rights of the Insurer and the
Indenture Trustee to direct such appointment pursuant to Section 7.03 of the
Sale and Servicing Agreement) appoint a Successor Master Servicer or Successor
Subservicer, which Successor Master Servicer or Successor Subservicer shall, so
long as no Insurer Default shall have occurred and be continuing, be acceptable
to the Insurer and such Successor Master Servicer or Successor Subservicer shall
accept its appointment by a written assumption in a form acceptable to the
Indenture Trustee and the Insurer. In the event that a Successor Master Servicer
or Successor Subservicer has not been appointed and accepted its appointment at
the time when the Master Servicer or the Subservicer ceases to act as Master
Servicer or Subservicer, the Indenture Trustee without further action shall
automatically be appointed the Successor Master Servicer or the Successor
Subservicer, as the case may be. The Indenture Trustee may resign as the
Successor Master Servicer or Successor Subservicer by giving written notice of
such resignation to the Issuer and the Insurer and in such event will be
released from such duties and obligations, such release not to be effective
until the date a new Master Servicer or Subservicer enters into an
administrative agreement or servicing agreement as provided below. Upon delivery
of any such notice to the Issuer, the Issuer shall obtain a new Master Servicer
as the Successor Master Servicer or new Subservicer as the Successor
Subservicer, as the case may be, each case which successor shall, so long as no
Insurer Default shall have occurred and be continuing, be acceptable to the
Insurer. Any Successor Master Servicer or Successor Subservicer other than the
Indenture Trustee shall (i) be an established financial institution having a net
worth of not less than $50,000,000 and whose regular business includes the
servicing of motor vehicle receivables and (ii) enter into an administrative
agreement or servicing agreement with the Issuer and the Depositor having
substantially the same provisions as the provisions of the Sale and Servicing
Agreement applicable to the Master Servicer or the Subservicer, as the case may
be. If within 30 days after the delivery of the notice referred to above, the
Issuer shall not have obtained such a new Master Servicer or Subservicer, the
Issuer may appoint, or may petition a court of competent jurisdiction to
appoint, a Successor Master Servicer or Successor Subservicer. In connection
with any such appointment, the Issuer may make such arrangements for the
compensation of such successor as it and such successor shall agree with, so
long as no Insurer Default shall have occurred and be continuing, the prior
written consent of the Insurer, subject to the limitations set forth below and
in the Sale and Servicing Agreement, and in accordance with Section 7.03 of the
Sale and Servicing Agreement, the Issuer shall enter into an agreement with such
successor for the administration or servicing, as the case may be, of the
Receivables (such agreement to be in form and substance satisfactory to the
Indenture Trustee and, so long as no Insurer Default shall have occurred and be
continuing, the Insurer). If the Indenture Trustee shall succeed to the duties
of the Master Servicer or the Subservicer as provided herein, it shall do so in
its individual capacity and not in

                                      25
<PAGE>

its capacity as Indenture Trustee and, accordingly, except as otherwise provided
in the proviso to Section 6.01(a), the provisions of Article Six shall be
inapplicable to the Indenture Trustee in its duties as the successor to the
Master Servicer or the Subservicer and the administration and servicing of the
Receivables. In case the Indenture Trustee shall become successor to the Master
Servicer or the Subservicer under the Sale and Servicing Agreement, the
Indenture Trustee shall be entitled to appoint as Master Servicer or Subservicer
any one of its Affiliates or agents, so long as no Insurer Default shall have
occurred and be continuing, with the prior written consent of the Insurer,
provided that it shall be fully liable for the actions and omissions of such
Affiliate or agent in such capacity as Successor Master Servicer or Successor
Subservicer.

     (f)  The Issuer shall promptly notify the Depositor, the Trustees, the
Insurer and the Rating Agencies in writing of (i) any termination of the Master
Servicer or the Subservicer pursuant to the Sale and Servicing Agreement and
(ii) the appointment of each Successor Master Servicer or Successor Subservicer,
including the name and address thereof.

     (g)  The Issuer agrees that it will not waive timely performance or
observance by the Depositor, the Master Servicer, the Subservicer or the Seller
of their respective duties under the Basic Documents (i) if the effect thereof
would adversely affect the Insurer or the Holders of the Notes or (ii) so long
as no Insurer Default shall have occurred and be continuing, without the prior
written consent of the Insurer.

     Section 3.08.  Negative Covenants.  So long as any Notes are Outstanding,
                    ------------------
the Issuer shall not:

                                   REMEDIES

     Section 5.01.    Events of Default.  Wherever used herein, "Event of
                      -----------------
Default" 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):

            (i)    default by the Issuer 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;

            (ii)   default by the Issuer in the payment of the principal of or
     any installment of the principal of any Note when the same becomes due and
     payable;

            (iii)  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 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 60 days after there shall have been given, by
     registered or certified mail, to the Issuer and to the Indenture Trustee,
     so long as an Insurer Default shall not have occurred and be continuing, by
     the Insurer, or, if an Insurer Default shall have occurred and be
     continuing, to the Issuer by the Indenture Trustee or to the Issuer, the
     Depositor and the Indenture Trustee by the Holders of Notes evidencing not
     less than 25% of the Note Balance, a written notice specifying such default
     and requiring it to be remedied and stating that such notice is a "Notice
     of Default" hereunder;

            (iv)   any representation or warranty of the Issuer made in this
     Indenture or in any certificate or other writing delivered pursuant hereto
     or in connection herewith proving to have been incorrect in any material
     respect as of the time when the same shall have been made, and the
     circumstance or condition in respect of which such representation or
     warranty was incorrect shall not have been eliminated or otherwise cured
     for a period of 30 days after there shall have been given, by registered or
     certified mail, to the Issuer by the Depositor, the Indenture Trustee or
     the Insurer or to the Issuer, the Depositor, the Indenture Trustee and the
     Insurer by the Holders of Notes evidencing not less than 25% of the Note
     Balance, a written notice specifying such incorrect representation or
     warranty and requiring it to be remedied and stating that such notice is a
     notice of Default hereunder;

            (v)    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 Trust Estate 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 Trust Estate, or ordering the winding-up or
     liquidation of the Issuer's affairs, and

                                      35
<PAGE>

     such decree or order shall remain unstayed and in effect for a period of 60
     consecutive days;

            (vi)   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 Trust Estate, 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 any action by the Issuer in furtherance
     of any of the foregoing; or

            (vii)  the submission of a claim under the Insurance Policy;
provided, however, that unless an Insurer Default shall have occurred and be
continuing, neither the Depositor, the Indenture Trustee nor the Noteholders may
declare an Event of Default. If an Insurer Default shall not have occurred and
be continuing, an Event of Default shall occur only upon delivery by the Insurer
to the Depositor and the Indenture Trustee of notice of the occurrence of such
Event of Default.

     The Issuer shall deliver to the Depositor and a Responsible Officer of the
Indenture Trustee and the Insurer within five days after the occurrence thereof,
written notice in the form of an Officer's Certificate of any event which with
the giving of notice and the lapse of time or both would become an Event of
Default under clause (iii) or (iv) above, its status and what action the Issuer
is taking or proposes to take with respect thereto.

     Section 5.02.    Acceleration of Maturity; Rescission and Annulment.
                      --------------------------------------------------

     (a)  If an Event of Default shall have occurred and be continuing, so long
as no Insurer Default shall have occurred and be continuing, the Insurer shall
have the right, but not the obligation, upon prior written notice to each Rating
Agency, to declare all the Notes to be immediately due and payable, by a notice
in writing to the Issuer, the Indenture Trustee, the Depositor and each Rating
Agency, and upon any such declaration the unpaid principal amount of such Notes,
together with accrued and unpaid interest thereon through the date of
acceleration, shall become immediately due and payable.  The Indenture Trustee
shall 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 submit claims under the Insurance Policy
with respect to the Notes and the Certificates.

     (b)  If an Event of Default shall have occurred and be continuing and an
Insurer Default shall have occurred and be continuing, then the Indenture
Trustee or the Holders of Notes evidencing not less than 66 2/3% of the Note
Balance may, upon prior written notice to each Rating Agency, declare the Notes
to be immediately due and payable by written notice to the Issuer (and to the
Indenture Trustee if given by Noteholders) and the Master Servicer, and upon any
such declaration the unpaid principal amount of the Notes, together with accrued
and

                                      36
<PAGE>

unpaid interest thereon through the date of acceleration, shall become
immediately due and payable.

     (c)  At any time after such declaration of acceleration of maturity has
been made and before a judgment or decree for payment of the money due has been
obtained by the Indenture Trustee as hereinafter in this Article, the Holders of
Notes evidencing not less than 66 2/3% of the Note Balance, by written notice to
the Issuer and the Indenture Trustee, may rescind and annul such declaration of
acceleration and its consequences if:

          (i)    the Issuer has paid or deposited with the Indenture Trustee a
     sum sufficient to pay:

                 (A)  all payments of principal of and interest on all Notes and
          all other amounts that would then be due hereunder or upon such Notes
          if the Event of Default giving rise to such acceleration had not
          occurred plus all amounts owing to the Insurer under the Insurance
          Agreement and the other Basic Documents; and

                 (B)  all sums paid or advanced by the Indenture Trustee
          hereunder and the reasonable compensation, expenses, disbursements and
          advances of the Indenture Trustee and its agents and counsel; and

          (ii)   all Events of Default, other than the nonpayment of the
     principal of the Notes that has become due solely by such acceleration,
     have been cured or waived as provided in Section 5.12.

No such rescission shall affect any subsequent default or impair any right
consequent thereto.

     (d)  If an Event of Default shall have occurred and be continuing and an
Insurer Default shall not have occurred and be continuing, the Insurer may elect
to prepay all or any portion of the Note Balance on any Distribution Date by
depositing the principal amount to be prepaid, plus accrued but unpaid interest
thereon to such Distribution Date, in the Collection Account in immediately
available funds no later than 5:00 P.M., New York City time, on the related
Deposit Date; provided, however, that the Insurer shall fulfill its obligations
under the Insurance Policy.

     (e)  If an Event of Default shall have occurred and be continuing, no
Insurer Default shall have occurred and be continuing and the Note Balance shall
have been paid in full, the Insurer may elect to prepay all or any portion of
the Certificate Balance on any Distribution Date by depositing the principal
amount to be prepaid, plus accrued but unpaid interest thereon to such
Distribution Date, in the Collection Account in immediately available funds no
later than 5:00 P.M., New York City time, on the related Deposit Date; provided,
however, that the Insurer shall fulfill its obligations under the Insurance
Policy.

     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 it, for the

                                      37
<PAGE>

benefit of the Holders of the Notes, the whole amount then due and payable on
such Notes for principal and interest, with interest on the overdue principal
and, to the extent payment at such rate of interest shall be legally
enforceable, on overdue installments of interest at the related 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, disbursements and advances of the Indenture Trustee and its agents and
counsel and other amounts due and owing to the Indenture Trustee pursuant to
Section 6.07.

     (b)  In case the Issuer shall fail forthwith to pay such amounts upon such
demand, the Indenture Trustee, in its own name and as trustee of an express
trust, may institute a Proceeding for the collection of the sums so due and
unpaid, and may prosecute such Proceeding to judgment or final decree, and may
enforce the same against the Issuer or other obligor upon such Notes and collect
in the manner provided by law out of the property of the Issuer or other obligor
upon such Notes, wherever situated, the monies adjudged or decreed to be
payable.

     (c)  If an Event of Default occurs and is continuing, the Indenture Trustee
may, as more particularly provided in Section 5.04, in its discretion, proceed
to protect and enforce its rights and the rights of the Noteholders and the
Insurer 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.

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

          (i)  to file and prove a claim or claims for the entire 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, and all
     advances made, 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;

                                      38
<PAGE>

          (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 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, and all advances made, by the Indenture Trustee and each
predecessor Indenture Trustee except as a result of negligence or bad faith.

     (e)  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.

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

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

     Section 5.04.    Remedies; Priorities.
                      --------------------

     (a)  If an Event of Default shall have occurred and be continuing, the
Indenture Trustee shall, so long as no Insurer Default shall have occurred and
be continuing, at the written direction of the Insurer, or, if an Insurer
Default shall have occurred and be continuing, at the written direction of the
Holders of Notes evidencing not less than 66 2/3% of the Note Balance, do one or
more of the following actions as so directed (subject to Sections 5.02 and
5.05):

                                      39
<PAGE>

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

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

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

          (iv)   sell the Trust Estate or any portion thereof or rights or
     interest therein, at one or more public or private sales called and
     conducted in any manner permitted by law;

provided, however, that the Indenture Trustee may not sell or otherwise
liquidate the Trust Estate at the direction of the Insurer following an Event of
Default, other than an Event of Default described in Section 5.01(i) or (ii),
unless the proceeds of such sale or liquidation will be sufficient to discharge
in full all amounts then due and unpaid upon the Notes for principal and
interest; provided, further, that the Indenture Trustee may not sell or
otherwise liquidate the Trust Estate at the direction of the Holders following
an Event of Default, other than an Event of Default described in Section 5.01(i)
or (ii), unless (A) the Holders of 100% of the Note Balance consent thereto, (B)
the proceeds of such sale or liquidation distributable to the Noteholders are
sufficient to discharge in full all amounts then due and unpaid upon such
Securities for principal and interest and all amounts due to the Insurer under
the Insurance Agreement or (C) the Indenture Trustee determines that the Trust
Estate will not continue to provide sufficient funds for the payment of
principal of and interest on the Notes as would have become due if the Notes had
not been declared due and payable, and the Indenture Trustee obtains the consent
of Holders of Notes evidencing not less than 66 2/3% of the Note Balance.  In
determining such sufficiency or insufficiency with respect to clause (B) and (C)
above, the Indenture Trustee may, but need not, 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
Trust Estate for such purpose.

     (b)  If the Indenture Trustee collects any money or property pursuant to
this Article, it shall pay out the money or property in the following order and
priority:

          (i)  to the Indenture Trustee and the Owner Trustee, any amounts due
     under the Trust Agreement or Section 6.07 hereof;

          (ii) to the Master Servicer, all accrued but unpaid Servicing Fees
     under the Sale and Servicing Agreement; provided, however, that to the
     extent the Master Servicer fails to pay the related Subservicer Fee,
     including any unpaid Subservicer Fee for previous Collection Periods, to
     the Subservicer, an amount equal to the lesser of the amount otherwise
     payable to the Master Servicer and the amount owing to the

                                      40
<PAGE>

     Subservicer will instead be paid to the Subservicer and the remainder of
     such amount, if any, will be paid to the Master Servicer;

            (iii)   to the Holders of the Notes of each Class, the Note Interest
     Distributable Amount ratably in proportion to the Note Interest
     Distributable Amount for each Class at their respective Interest Rates;

            (iv)    to the Holders of Notes of all Classes, the outstanding
     principal amount of the Notes, pro rata in proportion to the outstanding
     principal amount of each Class;

            (v)     to the Holders of Certificates, all accrued but unpaid
     interest on the Certificates;

            (vi)    to the Holders of Certificates, the outstanding principal
     balance of the Certificates;

            (vii)   to the Insurer, all overdue Insurance Premiums;

            (viii)  to the Insurer, the aggregate amount of any unreimbursed
     payments under the Insurance Policy, including any amount deposited by the
     Insurer pursuant to Section 5.02(d) or (e), plus accrued interest on any
     unreimbursed payments under the Insurance Policy, including any amount
     deposited by the Insurer pursuant to Section 5.02(d) or (e), at the rate
     provided in the Insurance Agreement plus any other amounts due the Insurer
     under the Insurance Agreement and any other Basic Document plus any
     unreimbursed Insurer Defense Costs;

            (ix)    to the Subservicer, for any remaining amounts due and unpaid
     in respect of the Subservicer Fee under the Sale and Servicing Agreement;
     and

            (x)     to the Seller, as holder of the Residual Interest, any
     remaining money or property.

The Indenture Trustee may fix a record date and distribution 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 distribution date and the amount to be
paid.

     Section 5.05.    Optional Preservation of the Receivables.  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 may, so long as no Insurer Default shall have
occurred and be continuing, at the direction of the Insurer, elect to maintain
possession of the Trust Estate and apply proceeds as if there had been no
declaration of acceleration; provided however, that the Available Funds shall be
applied in accordance with such declaration of acceleration in the manner
specified in Section 4.05(d) of the Sale and Servicing Agreement.  It is the
desire of the parties hereto and the Noteholders that there be at all times
sufficient funds for the payment of principal of and interest on the Notes, and
the Indenture Trustee shall take such desire into account when determining
whether or not to maintain possession of the Trust Estate.  In determining
whether to maintain possession of the Trust

                                      41
<PAGE>

Estate, the Indenture Trustee may, but need not, 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
Trust Estate for such purpose.

     Section 5.06.    Limitation of Suits.  No Holder of any Note shall have any
                      -------------------
right to institute any Proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless:

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

            (ii)    the Holders of Notes evidencing not less than 25% of the
     Note Balance 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
     evidencing not less than 51% of the Note Balance; and

            (vi)    an Insurer Default has occurred and is 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 51% of the Note Balance, the Indenture Trustee in
its sole discretion may determine what action, if any, shall be taken,
notwithstanding any other provisions of this Indenture.  The Indenture Trustee
shall not be liable for any such determination made in good faith.

     Section 5.07.    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, if any, 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, 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 5.08.    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 Insurer, the Indenture Trustee and the Noteholders shall,
subject to any determination in such Proceeding, be restored severally and
respectively to their former positions hereunder, and thereafter all rights and
remedies of the Indenture Trustee and the Noteholders shall continue as though
no such Proceeding had been instituted.

     Section 5.09.    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 5.10.    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 or by law to the Indenture Trustee, the Insurer or the Noteholders may
be exercised from time to time, and as often as may be deemed expedient, by the
Indenture Trustee, the Insurer or the Noteholders, as the case may be.

     Section 5.11.    Control by Noteholders.  The Holders of Notes evidencing
                      ----------------------
not less than 51% of the Note Balance 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)    subject to the terms of Section 5.04, any direction to the
     Indenture Trustee to sell or liquidate the Trust Estate shall be by the
     Insurer or the Holders of Notes representing not less than 100% of the Note
     Balance;

            (iii)   if the conditions set forth in Section 5.05 have been
     satisfied and the Indenture Trustee elects to retain the Trust Estate
     pursuant to such Section, then any direction to the Indenture Trustee by
     the Holders of Notes representing less than 100% of the Note Balance to
     sell or liquidate the Trust Estate shall be of no force and effect; and

            (iv)    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 reasonably
believes might involve it in costs,

                                      43
<PAGE>

expenses and liabilities for which it will not be adequately indemnified or
might materially adversely affect the rights of any Noteholders not consenting
to such action.

     Section 5.12.    Waiver of Past Defaults.  Prior to the declaration of the
                      -----------------------
acceleration of the maturity of the Notes as provided in Section 5.02, so long
as no Insurer Default shall have occurred and be continuing, the Insurer or the
Holders of Notes evidencing not less than 51% of the Note Balance, with the
consent of the Insurer, so long as no Insurer Default shall have occurred and be
continuing, may, on behalf of all Noteholders, waive any past Default or Event
of Default and its consequences except a Default or Event of Default (i) in
payment of principal of or interest on any of the Notes or (ii) in respect of a
covenant or provision hereof which cannot be modified, supplemented or amended
without the consent of the Holder of each Note.  In the case of any such waiver,
the Issuer, the Insurer, the Indenture Trustee and the Holders of the Notes
shall respectively be restored to their former positions and rights hereunder;
but no such waiver shall extend to any subsequent or other Default or Event of
Default or impair any right consequent thereto.  Upon any such waiver, such
Default or Event of 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 5.13.    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 Notes evidencing in the aggregate more than
10% of the Note Balance 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 5.14.    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 any 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 advantage 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 5.15.    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

                                      44
<PAGE>

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 Trust Estate 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 5.04(b).

     Section 5.16.    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 Depositor, the Seller, the Master Servicer or the Subservicer,
as applicable, of each of their obligations to the Issuer under or in connection
with the Sale and Servicing Agreement in accordance with the terms thereof, and
to exercise any and all rights, remedies, powers and privileges lawfully
available to the Issuer under or in connection with the Sale and Servicing
Agreement to the extent and in the manner directed by the Indenture Trustee,
including the transmission of notices of default on the part of the Depositor,
the Seller, the Master Servicer or the Subservicer thereunder and the

Trustee may, and at the direction (which direction shall be in writing or by
telephone (confirmed in writing promptly thereafter)) of the Holders of Notes
evidencing not less than 66 2/3% of the Note Balance shall, exercise all rights,
remedies, powers, privileges and claims of the Issuer against the Depositor, the
Seller, the Master Servicer or the Subservicer under or in connection with the
Sale and Servicing Agreement or against the Seller under or in connection with
the Receivables Purchase Agreement, including the right or power to take any
action to compel or secure performance or observance by the Depositor, the
Master Servicer or the Subservicer, 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 or the Receivables
Purchase Agreement, and any right of the Issuer to take such action shall be
suspended.

     (c)  Promptly following a request from the Indenture Trustee to do so and
at the Administrator's expense, the Issuer agrees to take all such lawful action
as the Indenture Trustee may request to compel or secure the performance and
observance by the Seller of each of its obligations to the Depositor under or in
connection with the Receivables Purchase Agreement in accordance with the terms
thereof, and to exercise any and all rights, remedies, powers and privileges
lawfully available to the Depositor or the Issuer under or in connection with
the Receivables Purchase 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 thereunder and the institution of legal or administrative
actions or proceedings to compel or secure performance by the Seller of each of
its obligations under the Receivables Purchase Agreement.

     (d)  If an Event of Default shall have occurred and be continuing, the

of the Depositor against the Seller under or in connection with the Receivables
Purchase Agreement, including the right or power to take any action to compel or
secure performance or observance by the Seller of each of its obligations to the
Depositor thereunder and to give any consent, request, notice, direction,
approval, extension or waiver under the Receivables Purchase Agreement, and any
right of the Depositor to take such action shall be suspended.

                                  ARTICLE SIX

                             THE INDENTURE TRUSTEE

     Section 6.01.    Duties of Indenture Trustee.
                      ---------------------------

     (a)  If an Event of Default has occurred and is continuing of which a
Responsible Officer of the Indenture Trustee has actual knowledge, the Indenture
Trustee shall exercise the rights and powers vested in it by this Indenture and
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; provided, however, that if the Indenture Trustee shall assume the
duties of the Master Servicer or the Subservicer, as the case may be, 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
Master Servicer or Subservicer, as the case may be, with respect to retail motor
vehicle installment sale contracts that it administers or services, as the case
may be, for itself or others.

     (b)  Except during the continuance of an Event of Default:

            (i)  the Indenture Trustee shall undertake 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; provided, however, the Indenture Trustee
     shall examine the certificates and opinions to determine whether or not
     they conform to the requirements of this Indenture.

     (c) The Indenture Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act or its own willful
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 of the Indenture
     Trustee 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 5.11.

     (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 except as the Indenture Trustee may agree in writing with the
Issuer.

                                      47
<PAGE>

     (f)  The Indenture Trustee acknowledges that it has reviewed the Sale and
Servicing Agreement and agrees to perform all acts required to be performed by
it thereunder.  The Indenture Trustee shall be entitled to the benefits of this
Section and references herein to the Indenture shall be read as references to
the Indenture and the Sale and Servicing Agreement.

     (g)  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.

     (h)  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 hereunder, if it shall have reasonable grounds to believe that
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

     (i)  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.

     (j)  The Indenture Trustee shall not be charged with knowledge of any Event
of Default unless either (i) a Responsible Officer of the Indenture Trustee
shall have actual knowledge of such Event of Default or (ii) written notice of
such Event of Default shall have been given to the Indenture Trustee in
accordance with the provisions of this Indenture.

     Section 6.02.    Rights of Indenture Trustee.
                      ---------------------------

     (a)  Except as otherwise provided in the second succeeding sentence, the
Indenture Trustee may rely on any 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, calculation or matter stated in the document.
Notwithstanding the foregoing, the Indenture Trustee, upon receipt of all
resolutions, certificates, statements, opinions, reports, documents, orders or
other instruments furnished to the Indenture Trustee that shall be specifically
required to be furnished pursuant to any provision of this Indenture, shall
examine them to determine whether they comply as to form to the requirements of
this Indenture.

     (b)  Before the Indenture Trustee acts or refrains from acting, it may
require an Officer's Certificate or an Opinion of Counsel.  The Indenture
Trustee shall not be liable for any action it takes or omits to take in good
faith in reliance on an Officer's Certificate or Opinion of Counsel unless it is
proved that the Indenture Trustee was negligent in such reliance.

     (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, or for the
supervision of, any such agent, attorney, custodian or nominee appointed with
due care by it hereunder.

     (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,

                                      48
<PAGE>

that such action or omission by the Indenture Trustee 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 rights or powers vested in it by this Indenture at the request or direction
of the Insurer or any of the Noteholders pursuant to this Indenture, unless such
Noteholders shall have offered to the Indenture Trustee security or indemnity
satisfactory to it against the costs, expenses and liabilities which might be
incurred by it in compliance with such request or direction.

     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 must 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 Trust Estate 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 if it is known to a Responsible Officer of the Indenture Trustee, the
Indenture Trustee shall mail to the Insurer and each Noteholder notice of the
Default within 30 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 mandatory redemption provisions of such Note), 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, within a reasonable period of time after the end of each
calendar year, to each Person who at any time during such calendar year was a
Noteholder, such information furnished to the Indenture Trustee as may be
required to enable such Person to prepare its federal and state income tax
returns.

     Section 6.07.    Compensation and Indemnity.
                      --------------------------

     (a)  The Master Servicer shall (i) pay to the Indenture Trustee from time
to time reasonable compensation for its services, which compensation shall not
be limited by any law on compensation of a trustee of an express trust and (ii)
reimburse the Indenture Trustee for all reasonable out-of-pocket expenses
incurred or made by it, including costs of collection, in

                                      49
<PAGE>

addition to the compensation for its services, which expenses shall include the
reasonable compensation and expenses, disbursements and advances of the (a)
Indenture Trustee as Administrator and (b) Indenture Trustee's agents, counsel,
accountants and experts; provided, however, that the Master Servicer need not
reimburse the Indenture Trustee for any expense incurred through the Indenture
Trustee's willful misconduct, negligence or bad faith.

     The Master Servicer's payment obligations to the Indenture Trustee pursuant
to this Section shall survive the discharge of this Indenture or the earlier
resignation or discharge of the Indenture Trustee.  When the Indenture Trustee
incurs expenses after the occurrence of a Default specified in Section 5.01(v)
or (vi) 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.

     (b)  The Master Servicer shall indemnify the Indenture Trustee and its
officers, directors, employees and agents against any and all loss, liability or
expense (including reasonable attorneys' fees and expenses) incurred by it in
connection with the administration of this trust and the performance of its
duties hereunder not resulting from its own willful misconduct, negligence or
bad faith.  The Indenture Trustee shall notify the Master Servicer and the
Administrator promptly of any claim for which it may seek indemnity.  Failure by
the Indenture Trustee to so notify the Master Servicer and the Administrator
shall not relieve the Master Servicer or the Administrator of its obligations
hereunder.  The Master Servicer shall, or shall cause the Administrator to,
defend any such claim, and the Indenture Trustee may have separate counsel and
the Master Servicer 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.

     Section 6.08.    Replacement of Indenture Trustee.  No resignation or
                      --------------------------------
removal of the Indenture Trustee and no appointment of a successor Indenture
Trustee shall become effective until the acceptance of appointment by the
successor Indenture Trustee pursuant to this Section.  The Indenture Trustee may
resign at any time by so notifying the Issuer, the Insurer, the Depositor and
the Noteholders.  So long as no Insurer Default shall have occurred and be
continuing, the Insurer, or the Noteholders evidencing not less than 51% of the
Note Balance, with, so long as no Insurer Default shall have occurred and be
continuing, the consent of the Insurer, may remove the Indenture Trustee (with a
copy to the Issuer, the Depositor, the Insurer and the Rating Agencies) at any
time and appoint a successor Indenture Trustee by so notifying the Indenture
Trustee and the Insurer.  The Issuer shall remove the Indenture Trustee 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

                                      50
<PAGE>

     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 the Indenture Trustee for any reason (the Indenture Trustee in
such event being referred to herein as the retiring Indenture Trustee), the
Issuer, with, so long as no Insurer Default shall have occurred and be
continuing, the consent of the Insurer, shall promptly appoint a successor
Indenture Trustee.

     Each successor Indenture Trustee shall deliver a written acceptance of its
appointment to the retiring Indenture Trustee, the Insurer, the Issuer and the
Depositor. 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 successor Indenture Trustee shall mail a notice of its succession to the
Noteholders. The retiring Indenture Trustee shall promptly transfer all property
held by it as Indenture Trustee to the successor Indenture Trustee.

     If a successor Indenture Trustee does not take office within 60 days after
the retiring Indenture Trustee resigns or is removed, the retiring Indenture
Trustee, the Issuer or the Holders of Notes evidencing not less than 51% of the
Note Balance 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 Issuer's and the Administrator's
obligations under Section 6.07 shall continue for the benefit of the retiring
Indenture Trustee.

     Section 6.09.  Successor Indenture Trustee by Merger. If the Indenture
                    -------------------------------------
Trustee consolidates or merges with, converts or transfers all or substantially
all its corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee

                                      51
<PAGE>

corporation or banking association shall, without any further act, 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 provide the Insurer and each Rating Agency prior written
notice of any such transaction.

     In case at the time such successor or successors 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 Indenture 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 as is provided anywhere in the Notes or in this
Indenture that the certificate of the Indenture Trustee shall have.

     Section 6.10.  Appointment of Co-Trustee or Separate 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 Trust Estate may at the time be located, the Indenture Trustee
and the Administrator, acting jointly, shall have the power and may execute and
deliver an instrument 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 Estate, and to vest in such Person or
Persons, in such capacity and for the benefit of the Insurer and the
Noteholders, such title to the Trust Estate or any part thereof, 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. If the
Administrator shall not have joined in such appointment within 15 days after its
receipt of a request to do so, the Indenture Trustee alone shall have the power
to make such appointment. No co-trustee or separate trustee hereunder shall be
required to meet the terms of eligibility as a successor trustee under Section
6.11 and no notice to Noteholders of the appointment of any co-trustee or
separate trustee shall be required under Section 6.08.

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

             (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 Estate 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;


                                      52
<PAGE>

          (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 and the Administrator 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 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 of this Indenture
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 and a copy thereof given to the Administrator.

     (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.

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.

     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

indicated.

                    --------

     (a)  On or prior to the Closing Date, the Issuer shall cause the Master
Servicer to establish and maintain, in the name of the Indenture Trustee, for
the benefit of (i) the Securityholders and the Insurer, the Collection Account

provided in Section 4.01 of the Sale and Servicing Agreement. The Collection
Account, Note Distribution Account and the Reserve Fund shall be Eligible
Accounts.

     (b)  On or before each Distribution Date, all amounts required to be
deposited in the Collection Account will be deposited as provided in Sections
4.02 and 4.04 of the Sale and Servicing Agreement. On or before each
Distribution Date, all amounts required to be deposited in the Note Distribution
Account with respect to the related Collection Period pursuant to Sections 4.04
and 4.05 of the Sale and Servicing Agreement will be transferred from the

Noteholders in respect of the Notes to the extent of amounts due and unpaid on
the Notes for principal and interest in the following amounts and in the
following order of priority (except as otherwise provided in Section 5.04(b)):

             (i)    the Note Interest Distributable Amount; provided, that if
     there are not sufficient funds in the Note Distribution Account to pay the
     allocable portion of the Note Interest Distribution Amount with respect to
     each Class of Notes, the amount in the Note Distribution Account shall be
     applied to the payment of such amount pro rata on the basis of the total
     Note Interest Distributable Amount due on the Notes;

             (ii)   the Note Principal Distributable Amount (first to the Class
     A-1 Notes until the Class A-1 Notes have been paid in full, second to the
     Class A-2 Notes until the

     Notes until the Class A-4 Notes have been paid in full);

             (iii)  notwithstanding the foregoing, on each Distribution Date
     after the Notes have been accelerated as provided in Section 5.02(a)
     following the occurrence of an Event of Default, until such time as the
     Notes have been paid in full and this Indenture has been discharged with
     respect to the Notes, the Certificates will not receive any of the
     Principal Distributable Amount, and the Notes will receive 100% of the
     Principal Distributable Amount on a pro rata basis based on the Note
     Balance of each Class of Notes; and

             (iv)   in the event that there are insufficient funds in the Note
     Distribution Account to make the foregoing distributions, an amount will be
     withdrawn from the Reserve Fund pursuant to Section 4.06(b) of the Sale and
     Servicing Agreement.

continuing, all or a portion of the funds in the Accounts shall be maintained in
cash or invested in Permitted Investments and reinvested by the Indenture
Trustee upon the written direction of the Master Servicer, subject to the
provisions of Section 4.01(b) of the Sale and Servicing Agreement. Except as
otherwise provided in Section 4.01(b) of the Sale and Servicing Agreement, all
income or other gain from investment of monies deposited in the Accounts (other
than the Reserve Fund) shall be part of Available Interest and any loss
resulting from such investments shall be charged to the related Account.

     (b)  Subject to Section 6.01(c), the Indenture Trustee shall not in any way
be held liable by reason of any insufficiency in any of the Accounts resulting
from any loss on any Permitted Investment included therein except for losses
attributable to the Indenture Trustee's failure to make payments on such
Permitted Investments issued by the Indenture Trustee, in its commercial
capacity as principal obligor and not as trustee, in accordance with their
terms.

     (c)  If (i) the Master Servicer shall have failed to give investment
directions for any funds on deposit in the Accounts to the Indenture Trustee by
8:00 A.M., Los Angeles time (or such other time as may be agreed by the Issuer
and the Indenture Trustee) on any Business Day or (ii) to the knowledge of a
Responsible Officer of the Indenture Trustee a Default or Event of Default shall
have occurred and be continuing with respect to the Notes but the Notes shall
not have been declared due and payable pursuant to Section 5.02 or (iii) if the
Notes shall have been declared due and payable following an Event of Default but
amounts collected or receivable from the Trust Estate are being applied in
accordance with Section 5.05 as if there had not been such a declaration, then
the Indenture Trustee upon actual knowledge by a Responsible Officer of the
Indenture Trustee of such event shall, to the fullest extent practicable, invest
and reinvest funds in the Accounts in the Permitted Investment listed in clause

                    -----------------------

     (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, the Insurance Policy has been terminated in accordance with its
terms and has been returned to the Insurer for cancellation and all sums due the
Insurer have been paid in full and all sums due the Indenture Trustee pursuant
to Section 6.07 have been paid in full, release any remaining portion of the
Trust Estate 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 Accounts. The Indenture Trustee shall release property from the lien of this
Indenture pursuant to this Section 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.

                    ------------------
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, except in connection with any
action contemplated by Section 8.04(b), as a condition to such action, an
Opinion of Counsel, in form and substance satisfactory to 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 Trust Estate. 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.

     (a)  The Issuer and the Indenture Trustee, when authorized by an Issuer
Order, may, without the consent of the Holders of any Notes but with the consent
of the Rating Agencies and, so long as no Insurer Default shall have occurred
and be continuing, the consent of the Insurer, with prior written notice to the
Insurer and the Rating Agencies at any time and from time to time, enter into
one or more indentures supplemental hereto, in form satisfactory to the
Indenture Trustee, for any of the following purposes:

             (i)    to correct or amplify the description of any property at any
     time subject to the lien of this Indenture, or better to assure, convey and
     confirm unto the Indenture Trustee any property subject or required to be
     subjected to the lien of this Indenture, or to subject additional property
     to the lien of this Indenture;

             (ii)   to evidence the succession, in compliance with the
     applicable provisions hereof, of another Person to the Issuer, and the
     assumption by any such successor of the covenants of the Issuer 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
     conferred upon the Issuer;

             (iv)   to convey, transfer, assign, mortgage or pledge any property
     to or with the Indenture Trustee;

             (v)    to cure any ambiguity, to correct or supplement any
     provision herein or in any supplemental indenture that may be inconsistent
     with any other provision herein or in any supplemental indenture or the
     other 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
     be expressly required by the TIA;

provided, however, that (i) no such supplemental indenture may materially
adversely affect the interests of any Noteholder or Certificateholder, (ii) no
such supplemental indenture will be permitted unless an Opinion of Counsel is
delivered to the Insurer and the Indenture Trustee to

                                      60
<PAGE>

the effect that such supplemental indenture will not cause the Issuer to be
characterized for federal income tax purposes as an association taxable as a
corporation or otherwise have any material adverse impact on the federal income
taxation of any Notes Outstanding or outstanding Certificates or any Noteholder
or Certificateholder and (iii) no such supplemental indenture will be permitted
without the consent of the Insurer if such supplemental indenture would
reasonably be expected to materially adversely affect the interests of the
Insurer. A supplemental indenture shall be deemed not to materially adversely
affect the interests of any Noteholder or Certificateholder if (i) the Person
requesting such supplemental indenture obtains and delivers to the Indenture
Trustee an Opinion of Counsel to that effect or (ii) the Rating Agency Condition
is satisfied. 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.

Issuer and the Indenture Trustee, when authorized by an Issuer Order, also may,
with prior notice to each Rating Agency and the Insurer and with the consent of
the Holders of Notes evidencing not less than 51% of the Note Balance and, so
long as no Insurer Default has occurred and is continuing, the consent of the
Insurer, by Act of such Holders delivered to the Issuer and the Indenture
Trustee, at any time and from time to time 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 no such supplemental indenture (i) consented
to by the Insurer on behalf of the Noteholders pursuant to Section 11.19 may
materially adversely affect the interests of any Noteholder or
Certificateholder, (ii) will be permitted unless an Opinion of Counsel is
delivered to the Indenture Trustee and the Insurer to the effect that such
supplemental indenture will not cause the Issuer to be characterized for federal
income tax purposes as an association taxable as a corporation or otherwise have
any material adverse impact on the federal income taxation of any Notes
Outstanding or outstanding Certificates or any Noteholder or Certificateholder
and (iii) will be permitted without the consent of the Insurer if such
supplemental indenture would reasonably be expected to materially adversely
affect the interests of the Insurer; and, provided further, that no such
supplemental indenture shall, without the consent of the Holder of each
Outstanding Note affected thereby:

            (i)   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 Price with respect thereto, change
     the provisions of this Indenture relating to the application of collections
     on, or the proceeds of the sale of, the Trust Estate to payment of
     principal of or interest on the Notes, or change any place of payment
     where, or the coin or currency in which, any Note or the interest thereon
     is payable, or impair the right to institute suit for the enforcement of
     the provisions of this Indenture requiring the application of funds
     available therefor, as provided in Article Five, to the payment of any such
     amount due on the Notes on or after the respective due dates thereof (or,
     in the case of redemption, on or after the Redemption Date);

            (ii)  reduce the percentage of the Note Balance, the consent of the
     Holders of Notes which is required for any such supplemental indenture, or
     the consent of the Holders of Notes 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;

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

            (iv)    reduce the percentage of the Note Balance required to direct
     the Indenture Trustee to direct the Issuer to sell or liquidate the Trust
     Estate pursuant to Section 5.04 if the proceeds of such sale would be

     interest on the Notes or amend the provisions of this Article which specify
     the percentage of the Note Balance required to amend this Indenture or the
     other Basic Documents;

            (v)     modify any provision of this Section except to increase any
     percentage specified herein or provide that certain additional provisions
     of this Indenture or the Basic Documents cannot be modified or waived
     without the consent of the Holder of each Outstanding Note affected
     thereby;

            (vi)    modify any of the provisions of this Indenture in such
     manner as to affect the calculation of the amount of any payment of
     interest or principal due on any Note on any Distribution Date (including
     the calculation of any of the individual components of such calculation) or
     affect the rights of the Holders of Notes to the benefit of any provisions
     for the mandatory redemption of the Notes contained herein; or

            (vii)   permit the creation of any lien ranking prior to or on a
     parity with the lien of this Indenture with respect to any part of the
     Trust Estate or, except as otherwise permitted or contemplated herein,
     terminate the lien of this Indenture on any property at any time subject
     hereto or deprive the Holder of any Note of the security provided by the
     lien of this Indenture.

     The Administrator shall certify to the Indenture Trustee whether or not any
Notes would be affected by any supplemental indenture and any such certification
shall be conclusive upon the Holders of all Notes, whether theretofore or
thereafter authenticated and delivered hereunder.

     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 Issuer and the Indenture Trustee 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.

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

supplemental indenture that affects the Indenture Trustee's own rights, duties,
liabilities or immunities under this Indenture or otherwise.

the Indenture Trustee, the Issuer and the Holders of the Notes shall thereafter
be determined, exercised and enforced hereunder subject in all respects to such

supplemental indenture shall be and be deemed to be part of the terms and
conditions of this Indenture for any and all purposes.

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.
                     ----------

     (a)   The Outstanding Notes are subject to redemption in whole, but not in
part, pursuant to Section 8.01 of the Sale and Servicing Agreement, on any
Distribution Date on which the Master Servicer exercises its option to purchase
the Trust Estate pursuant to said Section, for a purchase price equal to the
Redemption Price; provided that the Issuer has available funds sufficient to pay
the Redemption Price.  The amount paid by the Master Servicer shall be treated
as collections in respect of the Receivables and applied to pay the unpaid
principal amount of the Notes plus accrued and unpaid interest thereon, the
Certificate Balance plus accrued and unpaid interest thereon and all amounts due
the Insurer under the Insurance Agreement.  The Master Servicer or the Issuer
shall furnish each Rating Agency and the Insurer notice of such redemption.  If
the Outstanding Notes are to be redeemed pursuant to this Section, the Master
Servicer or the Issuer shall furnish notice of such election to the Indenture
Trustee, the Depositor, the Insurer and the Rating Agencies not later than 20
days prior to the Redemption Date and the Issuer shall deposit by 8:00 A.M., Los
Angeles time, on the Redemption Date with the Indenture Trustee in the Note
Distribution Account the Redemption Price of the Notes to be redeemed, whereupon
all such Notes shall be due and payable on the Redemption Date upon the
furnishing of a notice complying with Section 10.02 to each Holder of the Notes.

     (b)   In the event that the assets of the Issuer are purchased by the
Master Servicer pursuant to Section 8.01(a) of the Sale and Servicing Agreement,
all amounts on deposit in the Note Distribution Account shall be paid to the
Noteholders up to the unpaid principal amount of the Notes and all accrued and
unpaid interest thereon. If such amounts are to be paid to Noteholders pursuant
to this Section, the Issuer shall, to the extent practicable, furnish or cause
the Master Servicer to furnish notice of such event to the Depositor, the
Indenture Trustee, the Insurer and the Rating Agencies not later than 20 days
prior to the Redemption Date, whereupon all such amounts shall be payable on the
Redemption Date.

     Section 10.02.   Form of Redemption Notice. Notice of redemption under
                      -------------------------
Section 10.01 shall be given by the Indenture Trustee by first-class mail,
postage prepaid, or by facsimile mailed or transmitted promptly following
receipt of notice from the Issuer or the Master Servicer pursuant to Section
10.01(a), but not later than ten 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 or facsimile number
appearing in the Note Register.

     All notices of redemption shall state:

               (i)    the Redemption Date;

               (ii)   the Redemption Price;

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

                                      64

               (iv)   that on the Redemption Date, the Redemption Price will
     become due and payable upon each Note and that interest thereon shall cease
     to accrue from and after the Redemption Date.

     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 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.

     Section 11.01.  Compliance Certificates and Opinions, etc.
                     -----------------------------------------

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

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

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

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

             (iii)   a statement that, in the opinion of each signatory, such
     signatory has made such examination or investigation as is necessary to
     enable such signatory to express an informed opinion as to whether or not
     such covenant or condition has been complied with; and

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

     (b)     (i)     Prior to the deposit of any Collateral or other property or
securities with the Indenture Trustee that is to be made the basis for the
release of any property or securities subject to the lien of 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 an Officer's
Certificate certifying or stating the opinion of each person signing such
certificate as to the fair value (within 90 days of such deposit) to the Issuer
of the Collateral or other property or securities to be so deposited.

             (ii)    Whenever the Issuer is required to furnish to the Indenture
     Trustee an Officer's Certificate certifying or stating the opinion of any
     signer thereof as to the matters described in clause (i) above, the Issuer
     shall also deliver to the Indenture Trustee an Independent Certificate as
     to the same matters, if the fair value to the Issuer of the

                                      66
<PAGE>

     property or securities to be so deposited and of all other such securities
     made the basis of any such withdrawal or release since the commencement of
     the then-current fiscal year of the Issuer, as set forth in the
     certificates delivered pursuant to clause (i) above and this clause (ii),
     is 10% or more of the Note Balance, but such a certificate need not be
     furnished with respect to any property or securities so deposited, if the
     fair value thereof to the Issuer as set forth in the related Officer's
     Certificate is less than $25,000 or less than 1% of the Note Balance.

             (iii)   Other than with respect to any release described in clause
     (A) or (B) of Section 11.01(b)(v), whenever any property or securities are
     to be released from the lien of this Indenture, the Issuer shall also
     furnish to the Indenture Trustee an Officer's Certificate certifying or
     stating the opinion of each person signing such certificate as to the fair
     value (within 90 days of such release) of the property or securities
     proposed to be released and stating that in the opinion of such person the
     proposed release will not impair the security under this Indenture in
     contravention of the provisions hereof.

             (iv)    Whenever the Issuer is required to furnish to the Indenture
     Trustee an Officer's Certificate certifying or stating the opinion of any
     signer thereof as to the matters described in clause (iii) above, the
     Issuer shall also furnish to the Indenture Trustee an Independent
     Certificate as to the same matters if the fair value of the property or
     securities and of all other property (other than property described in
     clauses (A) or (B) of Section 11.01(b)(v)) released from the lien of this
     Indenture since the commencement of the then-current calendar year, as set
     forth in the certificates required by clause (iii) above and this clause
     (iv), equals 10% or more of the Note Balance, but such 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 Note Balance.

             (v)     Notwithstanding Section 2.12 or any other provision of this
     Section, the Issuer may, without compliance with the requirements of the
     other provisions of this Section, (A) collect, liquidate, sell or otherwise
     dispose of Receivables and Financed Vehicles as and to the extent permitted
     or required by the Basic Documents and (B) make cash payments out of the
     Accounts as and to the extent permitted or required by the Basic Documents.

     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 such officer's certificate or

                                      67
<PAGE>

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 Seller, the Master Servicer, the Subservicer, the Depositor, the Issuer or
the Administrator, stating that the information with respect to such factual
matters is in the possession of the Seller, the Master Servicer, the
Subservicer, the Depositor, the Issuer or the Administrator, unless such
Authorized Officer or counsel knows, or in the exercise of reasonable care
should know, that the certificate or opinion or representations with respect to
such matters are erroneous.

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

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

          Section 11.03.  Acts of Noteholders.
                          -------------------

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

          (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.

                          ------------------------------
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 such Holder's 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 each Rating Agency,
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.

                          ---------------------------------------
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

<PAGE>

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, except as otherwise provided in
Section 3.07(e), 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.

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 shall and shall cause its 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 may reasonably
determine that such disclosure is consistent with its obligations hereunder.

otherwise provided herein, so long as no Insurer Default shall have occurred and
be continuing, the Insurer shall have the right to exercise all rights,

consent of the Insurer; provided, however, that, without the consent of each
Noteholder and Certificateholder affected thereby, the Insurer shall not
exercise such rights to amend this Indenture in any manner that requires the
consent of the Holder of each Outstanding Note adversely affected by such
amendment.

          Notwithstanding any other provisions of this Indenture to the
contrary, if an Insurer Default shall have occurred and be continuing, the
Insurer shall not have the right to take any action under this Indenture or to
control or direct the actions of the Issuer, the Depositor, the Indenture
Trustee or the Owner Trustee 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 Issuer, the Indenture Trustee, the
Owner Trustee, the Noteholders or the

                                      72

Certificateholders; provided, however, that no supplemental indenture pursuant
to Section 9.01 or 9.02 of this Indenture will be permitted without the consent
of the Insurer if such supplemental indenture would reasonably be expected to
materially adversely affect the interests of the Insurer.

pursuant to the Indenture.

     The Issuer will pay interest on this Note at the rate per annum shown above

preceding Distribution Date (after giving effect to all payments of principal
made on the preceding Distribution Date), or on the Closing Date in the case of
the first Distribution Date or if no interest has yet been paid, subject to

policy (the "Insurance Policy") issued by MBIA Insurance Corporation (the
"Insurer"), pursuant to which the Insurer has unconditionally guaranteed the
timely payment of the Note Distributable Amount on each Distribution Date, all

     This Note is one of a duly authorized issue of Notes of the Issuer,
designated as its _____% Asset Backed Notes, Class [A-1] [A-2] [A-3] [A-4] (the
"Class [A-1] [A-2] [A-3] [A-4] Notes"), all issued under the Indenture, to which
Indenture and all indentures supplemental thereto reference is hereby made for a
statement of the respective rights and obligations thereunder of the Issuer, the
Insurer, the Indenture Trustee and the Holders of the Notes. The Notes are
subject to all terms of the Indenture. Capitalized terms used herein that are
not otherwise defined shall have the meanings ascribed thereto in the Indenture.

     The Class A-1 Notes, the Class A-2 Notes, the Class A-3 Notes and the Class
A-4 Notes (collectively, the "Notes") are and will be equally and ratably
secured by the Collateral pledged as security therefor as provided in the
Indenture.

     Principal payable on the Notes will be paid on each Distribution Date in
the amount specified in the Indenture and in the Sale and Servicing Agreement.
As described above, the entire unpaid principal amount of this Note will be
payable on the earlier of the Class [A-1] [A-2] [A-3] [A-4] Final Distribution
Date and the Redemption Date, if any, selected pursuant to the Indenture.
Notwithstanding the foregoing, under certain circumstances, the entire unpaid
principal amount of the Class [A-1] [A-2] [A-3] [A-4] Notes shall be due and
payable following the occurrence and continuance of an Event of Default, if (i)
the Insurer (if an Insurer Default shall not have occurred and be continuing) or
(ii) the Indenture Trustee or the Holders of Notes evidencing not less than 66
2/3% of the Note Balance (if an Insurer Default shall have occurred and be
continuing) have declared the Notes to be immediately due and payable in the
manner provided in Section 5.02 of the Indenture. All principal payments on the
Class [A-1] [A-2] [A-3] [A-4] Notes shall be made pro rata to the Class [A-1]
[A-2] [A-3] [A-4] Noteholders entitled thereto.

     Payments of principal and interest on this Note due and payable on each
Distribution Date or Redemption Date shall be made by check mailed to the Person
whose name appears as the registered Holder of this Note (or one or more
Predecessor Notes) on the Note Register as of the close of business on the
related Record Date, except that with respect to Notes registered on the Record
Date in the name of the nominee of the Depository (initially, such nominee to be
Cede & Co.), payments will be made by wire transfer in immediately available
funds to the account designated by such nominee. Such checks shall be mailed to
the Person entitled thereto at the address of such Person as it appears on the
Note Register as of the applicable Record Date without requiring that this Note
be submitted for notation of payment. Any reduction in the principal amount of
this Note (or any one or more Predecessor Notes) affected by any payments made
on any Distribution Date or Redemption Date shall be binding upon all future
Holders of this Note and of any Note issued upon the registration of transfer
hereof or in exchange hereof or in lieu hereof, whether or not noted hereon. If
funds are expected to be available, as provided in the Indenture, for payment in
full of the remaining unpaid principal amount of this Note on a Distribution
Date or Redemption Date, then the Indenture Trustee, in the name of and on
behalf of the Issuer, will notify the Person who was the registered Holder
hereof as of the Record Date preceding such Distribution Date or Redemption Date
by notice mailed within five days of such Distribution Date or Redemption Date
and the amount then due and payable shall be payable only upon presentation and
surrender of this Note at the Corporate Trust Office of the Indenture Trustee or
at the office of the Indenture Trustee's agent appointed for such purposes
located in The City of New York.

     As provided in the Indenture and subject to the limitations set forth
therein and on the face hereof, the transfer of this Note may be registered on
the Note Register upon surrender of this Note for registration of transfer at
the office or agency designated by the Issuer pursuant to the Indenture, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Indenture Trustee duly executed by, the Holder hereof or
such Holder's attorney duly authorized in writing, with such signature
guaranteed by an "eligible guarantor institution" meeting the requirements of
the Note Registrar, all in accordance with the Securities Exchange Act of 1934,
as amended, and thereupon one or more new Notes of authorized denominations and
in the same aggregate principal amount will be issued to the designated
transferee or transferees. No service charge will be charged for any
registration of transfer or exchange of this Note, but the transferor may be
required to pay a sum sufficient to cover any tax or other governmental charge
that may be imposed in connection with any such registration of transfer or
exchange.

     Each Noteholder or Note Owner, by acceptance of a Note or, in the case of a
Note Owner, a beneficial interest in a Note, covenants and agrees that 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
the Indenture or any certificate or other writing delivered in connection
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 or employee 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 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.

     Each Noteholder or Note Owner, by acceptance of a Note or, in the case of a
Note Owner, a beneficial interest in a Note, covenants and agrees by accepting
the benefits of the Indenture that such Noteholder or Note Owner will not at any
time institute against the Depositor, the Purchaser or the Issuer, or join in
any institution against the Depositor or the Issuer of, any bankruptcy,
reorganization, arrangement, insolvency or liquidation proceedings under any
United States federal or state bankruptcy or similar law in connection with any
obligations relating to the Notes, the Certificates, the Indenture or the other
Basic Documents.

     A fiduciary of a Benefit Plan purchasing the Notes with the assets of a
Benefit Plan is deemed to represent that the purchase of one or more Notes is
consistent with its fiduciary duties under ERISA and does not result in a
nonexempt prohibited transaction as defined in Section 406 of ERISA or Section
4975 of the Code.

     The Issuer has entered into the Indenture and this Note is 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 Trust Estate. Each Noteholder, by acceptance of a Note (and each
Note Owner by acceptance of a beneficial interest in a Note), agrees to treat
the Notes for federal, state and local income, single business and franchise tax
purposes as indebtedness of the Issuer.

     Prior to the due presentment for registration of transfer of this Note, the
Issuer, the Insurer, the Indenture Trustee and any agent of the Issuer, the
Insurer or the Indenture Trustee may treat the Person in whose name this Note
(as of the day of determination or as of such other date as may be specified in
the Indenture) is registered as the owner hereof for all purposes, whether or
not this Note shall be overdue, and none of the Issuer, the Indenture Trustee or
any such agent shall be affected by notice to the contrary.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Holders of the Notes under the Indenture at any
time by the Owner Trustee, on behalf of the Issuer, without the consent of the
Holders of Notes but with, so long as no Insurer Default shall have occurred and
be continuing, the consent of the Insurer. The Indenture also contains
provisions permitting the Owner Trustee, on behalf of the Issuer, and the
Indenture Trustee, with certain exceptions as therein provided, to amend or
waive from time to time certain terms and conditions set forth in the Indenture
with, so long as no Insurer Default shall have occurred and be continuing, the
consent of the Insurer and the Holders of Notes evidencing not less than 51% of
the Note Balance. The Indenture also permits, so long as no Insurer Default
shall have occurred and be continuing, the Insurer or the Holders of Notes
evidencing not less than 51% of the Note Balance, with, so long as no Insurer
Default shall have occurred and be continuing, the consent of the Insurer, on
behalf of the Holders of all the Notes, to waive compliance by the Issuer with
certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences. Any such consent or waiver by the Insurer,
Holders of not less than 51% of the Note Balance or Holder of this Note (or any
one or more Predecessor Notes) shall be conclusive and binding upon such Holder
and upon all future Holders of this Note and of any Note issued upon the
registration of transfer hereof or in exchange hereof or in lieu hereof whether
or not notation of such consent or waiver is made upon this Note.

     The Indenture permits the Issuer, under certain circumstances, to
consolidate or merge with or into another Person, subject to the rights of the
Indenture Trustee and the Holders of Notes under the Indenture.

     The Notes are issuable only in registered form in denominations as provided
in the Indenture, subject to certain limitations therein set forth.

     This Note and the Indenture shall be construed in accordance with the laws
of the State of New York, without reference to its conflict of law provisions
(other than Section 5-1401 of the General Obligations Law), and the obligations,
rights and remedies of the parties hereunder and thereunder shall be determined
in accordance with such laws.

     No reference herein to the Indenture and no provision of this Note or of
the Indenture shall alter or impair the obligation of the Issuer, which is
absolute and unconditional, to pay the principal of and interest on this Note at
the times, place and rate, and in the coin or currency herein prescribed.
