together with Indenture Trustee's certificate of authentication, shall be in
substantially the forms set forth in Exhibits D and E, respectively, with such
appropriate insertions, omissions, substitutions and other variations as are

other marks of identification and such legends or endorsements placed thereon as
may, consistently herewith, be determined by the officers executing such Notes,
as evidenced by their execution of the Notes. Any portion of the text of any
Note may be set forth on the reverse thereof, with an appropriate reference
thereto on the face of the Note.

                  (b) The Definitive Notes shall be typewritten, printed,
lithographed or engraved or produced by any combination of these methods (with
or without steel engraved borders), all as determined by the officers executing
such Notes, as evidenced by their execution of such Notes.

                  (c) Each Note shall be dated the date of its authentication.
The terms of the Notes set forth in Exhibits D and E are part of the terms of
this Indenture.

                  SECTION 2.2 Execution, Authentication and Delivery. The Notes
shall be executed on behalf of Issuer by any of its Authorized Officers. The
signature of any such Authorized Officer on the Notes may be manual or
facsimile.

                  (a) Notes bearing the manual or facsimile signature of
individuals who were at any time Authorized Officers of Issuer shall bind
Issuer, notwithstanding that such individuals or any of them have ceased to hold
such offices prior to the authentication and delivery of such Notes or did not
hold such offices at the date of such Notes.

                  (b) Indenture Trustee shall upon Issuer Order authenticate and
deliver Class A- 1 Notes for original issue in an aggregate principal amount of
$____________ and Class A-2 Notes for original issue in the aggregate principal
amount of _________________. The aggregate principal amount of Class A-1 Notes

                  (c) Each Note shall be dated the date of its authentication.
The Notes shall be issuable as registered Notes in the minimum denomination of
$1,000 and in integral multiples thereof (except for one Note of each class
which may be issued in a denomination other than an integral multiple of
$1,000).

                  (d) No Note shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose, unless there appears on
such Note a certificate of authentication substantially in the form provided for
herein executed by Indenture Trustee by the manual


                                       3
<PAGE>   8


signature of one of its authorized signatories, and such certificate upon any
Note shall be conclusive evidence, and the only evidence, that such Note has
been duly authenticated and delivered hereunder.

                  SECTION 2.3 Temporary Notes.

                  (a) Pending the preparation of Definitive Notes, Issuer may
execute, and upon receipt of an Issuer Order, Indenture Trustee shall
authenticate and deliver, temporary Notes which are printed, lithographed,
typewritten, mimeographed or otherwise produced, of the tenor of the Definitive
Notes in lieu of which they are issued and with such variations not inconsistent
with the terms of this Indenture as the officers executing such Notes may
determine, as evidenced by their execution of such Notes.

                  (b) If temporary Notes are issued, Issuer will cause
Definitive Notes to be prepared without unreasonable delay. After the
preparation of Definitive Notes, the temporary Notes shall be exchangeable for
Definitive Notes upon surrender of the temporary Notes at the office or agency
of Issuer to be maintained as provided in Section 3.2, without charge to the
Holder. Upon surrender for cancellation of any one or more temporary Notes,
Issuer shall execute and Indenture Trustee shall authenticate and deliver in
exchange therefor a like principal amount of Definitive Notes of authorized
denominations. Until so exchanged, the temporary Notes shall in all respects be
entitled to the same benefits under this Indenture as Definitive Notes.

                  SECTION 2.4 Registration of Transfer and Exchange.

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

                  (b) If a Person other than Indenture Trustee is appointed by
Issuer as Note Registrar, Issuer will give 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 Indenture Trustee shall have
the right to inspect the Note Register at all reasonable times and to obtain
copies thereof, and Indenture Trustee shall have the right to conclusively rely
upon a certificate executed on behalf of 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.

                  (c) Upon surrender for registration of transfer of any Note at
the office or agency of Issuer to be maintained as provided in Section 3.2, if
the requirements of Section 8-401(1) of the UCC are met Issuer shall execute and
upon its written request Indenture Trustee shall authenticate and the Noteholder
shall obtain from Indenture Trustee, in the name of the designated transferee or
transferees, one or more new Notes, in any authorized denominations, of the same
class and a like aggregate principal amount.


                                       4
<PAGE>   9


                  (d) At the option of the Holder, Notes may be exchanged for
other Notes in any authorized denominations, of the same class and 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, if the
requirements of Section 8-401(1) of the UCC are met Issuer shall execute and
upon its written request Indenture Trustee shall authenticate and the Noteholder
shall obtain from Indenture Trustee, the Notes which the Noteholder making the
exchange is entitled to receive.

                  (e) All Notes issued upon any registration of transfer or
exchange of Notes shall be the valid obligations of 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.

                  (f) Every Note presented or surrendered for registration of
transfer or exchange shall be (i) duly endorsed by, or be accompanied by a
written instrument of transfer in form satisfactory to Note Registrar 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 Note Registrar which requirements include membership
or participation in a Securities Transfer Agents Medallion Program ("Stamp") or
such other "signature guarantee program" as may be determined by Note Registrar
in addition to, or in substitution for, Stamp, all in accordance with the
Exchange Act, and (ii) accompanied by such other documents as Indenture Trustee
may require.

                  (g) No service charge shall be made to a Holder for any
registration of transfer or exchange of Notes, but Issuer 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 2.3 or 9.6 not involving any transfer.

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

                  SECTION 2.5 Mutilated, Destroyed, Lost or Stolen Notes.

                  (a) If (i) any mutilated Note is surrendered to Indenture
Trustee, or Indenture Trustee receives evidence to its satisfaction of the
destruction, loss or theft of any Note, and (ii) there is delivered to Indenture
Trustee such security or indemnity as may be required by it to hold Issuer and
Indenture Trustee harmless, then, in the absence of notice to Issuer, Note
Registrar or Indenture Trustee that such Note has been acquired by a bona fide
purchaser, and provided that the requirements of Section 8-405 of the UCC are
met, Issuer shall execute and upon its written request Indenture Trustee shall
authenticate and deliver, in exchange for or in lieu of any such mutilated,
destroyed, lost or stolen Note, a replacement Note; provided 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, Issuer may upon delivery of
the security or indemnity herein required pay


                                       5
<PAGE>   10


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 6 destroyed, lost or stolen Note pursuant to
the proviso to the preceding sentence, a bona fide purchaser of the original
Note in lieu of which such replacement Note was issued presents for payment such
original Note, Issuer and Indenture Trustee shall be entitled to recover such
replacement Note (or such payment) from the Person to whom it was delivered or
any Person taking such replacement Note from such Person to whom such
replacement Note was delivered or any assignee of such Person, except a bona
fide purchaser, and shall be entitled to recover upon the security or indemnity
provided therefor to the extent of any loss, damage, cost or expense incurred by
Issuer or Indenture Trustee in connection therewith.

                  (b) Upon the issuance of any replacement Note under this
Section 2.5, Issuer 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 Indenture Trustee) connected therewith.

                  (c) Every replacement Note issued pursuant to this Section 2.5
in replacement of any mutilated, destroyed, lost or stolen Note shall constitute
an original additional contractual obligation of 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.

                  (d) The provisions of this Section 2.5 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 2.6 Persons Deemed Owner. Prior to due presentment for
registration of transfer of any Note, Issuer, Indenture Trustee and any agent of
Issuer or Indenture Trustee may treat the Person in whose name any Note is
registered (as of the day of determination) as the owner of such Note for the
purpose of receiving payments of principal of and interest, if any, on such Note
and for all other purposes whatsoever, whether or not such Note be overdue, and
neither Issuer, Indenture Trustee nor any agent of Issuer or Indenture Trustee
shall be affected by notice to the contrary.

                  SECTION 2.7 Payment of Principal and Interest.

                  (a) The Notes shall accrue interest as provided in the forms
of the Class A-1 Note and the Class A-2 Note, set forth in Exhibits D and E,
respectively, and such interest shall be payable on each Payment Date as
specified therein. Any installment of interest or principal, if any, payable on
any Note which is punctually paid or duly provided for by Issuer on the
applicable Payment Date shall be paid to the Person in whose name such Note (or
one or more Predecessor Notes) is registered on the Record Date, by check mailed
first-class, postage prepaid, to such Person's address as it appears on the Note
Register on such Record Date, except that, unless Definitive Notes have been
issued pursuant to Section 2.12, with respect to Notes registered on the Record
Date in the name of the nominee of the Clearing Agency (initially, such nominee
to be Cede & Co.), payment will be made by wire transfer in immediately
available funds to the account designated by such nominee and except for the
final installment of principal


                                       6
<PAGE>   11


payable with respect to such Note on a Payment Date or on the Final Scheduled
Payment Date (and except for the Redemption Price for any Note called for
redemption pursuant to Section 10.1(a)) which shall be payable as provided
below. The funds represented by any such checks returned undelivered shall be
held in accordance with Section 3.3.

                  (b) The principal of each Note shall be payable on each
Payment Date as provided in the forms of the Class A-1 Note and the Class A-2
Note, set forth in Exhibits D and E, respectively. Notwithstanding the
foregoing, the entire unpaid principal amount of the Notes shall be due and
payable, if not previously paid, on the date on which an Event of Default shall
have occurred and be continuing, if Indenture Trustee or the Holders of the
Notes representing not less than a majority of the Outstanding Amount of the
Notes have declared the Notes to be immediately due and payable in the manner
provided in Section 5.2 and, in such event, all principal payments on each class
of Notes shall be made pro rata to the Noteholders of such class entitled
thereto. Indenture Trustee shall notify the Person in whose name a Note is
registered at the close of business on the Record Date preceding the Payment
Date on which Issuer expects that the final installment of principal of and
interest on such Note will be paid. Such notice shall be mailed or transmitted
by facsimile prior to such final Payment Date and shall specify that such final
installment will be payable only upon presentation and surrender of such Note
and shall specify the place where such Note may be presented and surrendered for
payment of such installment. Notices in connection with redemptions of Notes
shall be mailed to Noteholders as provided in Section 10.2.

                  SECTION 2.8 Cancellation. All Notes surrendered for payment,
registration of transfer, exchange or redemption shall, if surrendered to any
Person other than Indenture Trustee, be delivered to Indenture Trustee and shall
be promptly cancelled by Indenture Trustee. Issuer may at any time deliver to
Indenture Trustee for cancellation any Notes previously authenticated and
delivered hereunder which Issuer may have acquired in any manner whatsoever, and
all Notes so delivered shall be promptly cancelled by 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 Indenture Trustee in
accordance with its standard retention or disposal policy as in effect at the
time unless 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 Indenture Trustee.

                  SECTION 2.9 Release of Collateral. Subject to Section 11.1,
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 TIA Sections
314(c) and 314(d)(1) or an Opinion of Counsel in lieu of such Independent
Certificates to the effect that TIA does not require any such Independent
Certificates. If the Commission shall issue an exemptive order under TIA Section
304(d) modifying Owner Trustee's obligations under TIA Sections 314(c) and
314(d)(1), subject to Section 11.1 and the terms of the Basic Documents,
Indenture Trustee shall release property from the lien of this Indenture in
accordance with the conditions and procedures set forth in such exemptive order.

                  SECTION 2.10 Book-Entry Notes. The Notes, upon original
issuance, will be issued in the form of typewritten Notes representing the
Book-Entry Notes, to be delivered to _____________________, as agent for The
Depository Trust Company, the initial Clearing Agency, by, or on behalf of,
Issuer. Such Notes shall initially be registered on the Note Register in the
name of Cede & Co., the nominee of the initial Clearing Agency, and no Note
Owner will receive a Definitive Note representing such Note Owner's interest in
such Note, except as provided in Section 2.12. Unless and until definitive,
fully registered Notes (the "Definitive Notes") have been issued to Note Owners
pursuant to Section 2.12:

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

                  (b) Note Registrar and 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;

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

                  (d) 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 or Persons acting through Clearing Agency Participants.
Pursuant to the Note Depository Agreement, unless and until Definitive Notes are
issued pursuant to Section 2.12, the initial 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

                  (e) whenever this Indenture requires or permits actions to be
taken based upon instructions or directions of Holders of Notes evidencing a
specified percentage of the Outstanding Amount of the Notes, 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 or Persons acting through Clearing Agency Participants owning or
representing, respectively, such required percentage of the beneficial interest
in the Notes and has delivered such instructions to Indenture Trustee.

                  SECTION 2.11 Notices to Clearing Agency. Whenever a notice or
other communication to the Noteholders is required under this Indenture, unless
and until Definitive Notes shall have been issued to Note Owners pursuant to
Section 2.12, Indenture Trustee shall give all such notices and communications
specified herein to be given to Holders of the Notes to the Clearing Agency, and
shall have no obligation to the Note Owners.

                  SECTION 2.12 Definitive Notes. If (a) Seller advises Indenture
Trustee in writing that the Clearing Agency is no longer willing or able to
properly discharge its responsibilities with respect to the Notes, and Seller is
unable to locate a qualified successor, (b) Seller at its option advises
Indenture Trustee in writing that it elects to terminate the book-entry system
through the Clearing Agency or (c) after the occurrence of an Event of Default,
Note Owners representing beneficial interests aggregating at least a majority of
the Outstanding


                                       8
<PAGE>   13


Amount of the Notes advise Indenture Trustee 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 the Note Owners, then the Clearing Agency
shall notify all Note Owners and Indenture Trustee of the occurrence of any such
event and of the availability of Definitive Notes to Note Owners requesting the
same. Upon surrender to Indenture Trustee of the typewritten Note or Notes
representing the Book-Entry Notes by the Clearing Agency, accompanied by
registration instructions, Issuer shall execute and Indenture Trustee shall
authenticate the Definitive Notes in accordance with the instructions of the
Clearing Agency. None of Issuer, Note Registrar or 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, Indenture Trustee shall recognize the Holders of the
Definitive Notes as Noteholders.

                  SECTION 2.13 Authenticating Agents.

                  (a) 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 2.2, 2.3, 2.4 and 2.5, 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."

                  (b) 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 further act on the part of the parties hereto or such
Authenticating Agent or such successor corporation.

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

                  (d) The Administrator agrees to pay to each Authenticating
Agent from time to time reasonable compensation for its services. The provisions
of Sections 2.8 and 6.4 shall be applicable to any Authenticating Agent.

                  SECTION 2.14 Tax Treatment. Issuer has entered into this
Indenture, and the Notes shall be issued, with the intention that, for federal,
state and local income and franchise tax purposes, the Notes shall qualify as
indebtedness of Issuer secured by the Trust Estate. 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


                                       9
<PAGE>   14


treat the Notes for federal, state and local income and franchise tax purposes
as indebtedness of Issuer.

                             ARTICLE III COVENANTS.

                  SECTION 3.1 Payment of Principal and Interest. Issuer will
duly and punctually pay the principal of and interest on the Notes in accordance
with the terms of the Notes and this Indenture. Without limiting the foregoing,
subject to Section 8.2(c), Issuer will cause to be distributed all amounts on
deposit in the Note Distribution Account on a Payment Date deposited therein
pursuant to the Sale and Servicing Agreement (i) in the Class A-1 Noteholders'
Interest Distributable Amount, to Class A-1 Noteholders and (ii) in the Class
A-2 Noteholders' Interest Distributable Amount, to Class A-2 Noteholders.
Amounts properly withheld under the Code by any Person from a payment to any
Noteholder of interest and/or principal shall be considered as having been paid
by Issuer to such Noteholder for all purposes of this Indenture.

                  SECTION 3.2 Maintenance of Office or Agency. 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 Issuer in respect of the Notes and this
Indenture may be served. Issuer hereby initially appoints Indenture Trustee to
serve as its agent for the foregoing purposes. Issuer will give prompt written
notice to Indenture Trustee of the location, and of any change in the location,
of any such office or agency. If at any time Issuer shall fail to maintain any
such office or agency or shall fail to furnish Indenture Trustee with the
address thereof, such surrenders, notices and demands may be made or served at
the Corporate Trust Office, and Issuer hereby appoints Indenture Trustee as its
agent to receive all such surrenders, notices and demands.

                  SECTION 3.3 Money for Payments To Be Held in Trust.

                  (a) As provided in Section 8.2, 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 8.2(c) shall be made on behalf of Issuer by 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
Issuer except as provided in this Section.

                  (b) On or before each Payment Date and Redemption Date, 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 Indenture Trustee) shall promptly notify Indenture
Trustee of its action or failure so to act.

                  (c) Issuer will cause each Paying Agent other than Indenture
Trustee to execute and deliver to Indenture Trustee an instrument in which such
Paying Agent shall agree with Indenture Trustee (and if 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


                                       10
<PAGE>   15


         to such Persons or otherwise disposed of as herein provided and pay
         such sums to such Persons as herein provided;

                  (ii) give Indenture Trustee notice of any default by 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 Indenture Trustee, forthwith pay to
         Indenture Trustee all sums so held in trust by such Paying Agent;

                  (iv) immediately resign as a Paying Agent and forthwith pay to
         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.

                  (d) 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 Indenture Trustee all sums held in trust
by such Paying Agent, such sums to be held by Indenture Trustee upon the same
trusts as those upon which the sums were held by such Paying Agent; and upon
such a payment by any Paying Agent to Indenture Trustee, such Paying Agent shall
be released from all further liability with respect to such money.

                  (e) Subject to applicable laws with respect to the escheat of
funds, any money held by 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 Issuer on Issuer Request; and the Holder of such Note
shall thereafter, as an unsecured general creditor, look only to Issuer for
payment thereof (but only to the extent of the amounts so paid to Issuer), and
all liability of Indenture Trustee or such Paying Agent with respect to such
trust money shall thereupon cease; provided that Indenture Trustee or such
Paying Agent, before being required to make any such repayment, shall at the
expense of 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 Issuer. Indenture Trustee shall also adopt and
employ, at the expense of Issuer, any other reasonable means of notification of
such repayment (including, but not limited to, mailing notice of such repayment
to Holders whose Notes have been called but have not been surrendered for
redemption or whose right to or interest in moneys due and payable but not
claimed is determinable from the records of Indenture Trustee or of any Paying
Agent, at the last address of record for each such Holder).

provisions of Section 3.10, Issuer will keep in full effect its existence,
rights and franchises as a _______________ under the laws of the State of
___________ (unless it becomes, or any successor Issuer hereunder is or becomes,
organized under the laws of any other state or of the United States of America,
in which case 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

                  SECTION 3.5 Protection of Trust Estate. Issuer will from time

supplements and amendments hereto and all such financing statements,
continuation statements, instruments of further assurance and other instruments,
and will take such other action necessary or advisable to:

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

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

Issuer hereby designates Indenture Trustee its agent and attorney-in-fact to

required by Issuer pursuant to this Section.

                  SECTION 3.6 Opinions as to Trust Estate.

                  (a) On the Closing Date, Issuer shall furnish to Indenture
Trustee an Opinion of Counsel either stating that, in the opinion of such
counsel, such action has been taken with respect to the recording and filing of

                  (b) Within 120 days after the beginning of each calendar year
which commences more than three months after the Cutoff Date, Issuer shall
furnish to Indenture Trustee an Opinion of Counsel either stating that, in the

are necessary to maintain the lien and security interest created by this
Indenture and reciting the details of such action or stating that in the opinion

                                       12

lien and security interest. Such Opinion of Counsel shall also describe the
recording, filing, re-recording and refiling of this Indenture, any indentures
supplemental hereto and any other requisite documents and the execution and
filing of any financing statements and continuation statements that will, in the
opinion of such counsel, be required to maintain the lien and security interest
of this Indenture until January 30 in the following calendar year.

                  SECTION 3.7 Performance of Obligations; Servicing of
Receivables.

                  (a) 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
ordered by any bankruptcy or other court or as expressly provided in this
Indenture, the Basic Documents or such other instrument or agreement.

                  (b) 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 Indenture Trustee in an Officer's Certificate of
Issuer shall be deemed to be action taken by Issuer. Initially, Issuer has
contracted with Servicer and the Administrator to assist Issuer in performing
its duties under this Indenture.

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

                  (d) If Issuer shall have knowledge of the occurrence of a
Servicer Termination Event under the Sale and Servicing Agreement, Issuer shall
promptly notify Indenture Trustee and the Rating Agencies thereof in accordance
with Section 11.4, and shall specify in such notice the action, if any, Issuer
is taking in respect of such default. If a Servicer Termination Event shall
arise from the failure of Servicer to perform any of its duties or obligations
under the Sale and Servicing Agreement with respect to the Receivables, Issuer
shall take all reasonable steps available to it to remedy such failure.

                  (e) As promptly as possible after the giving of notice of
termination to Servicer of Servicer's rights and powers pursuant to Section 8.1
of the Sale and Servicing Agreement, Issuer shall appoint a successor servicer
(the "Successor Servicer"), and such Successor Servicer shall accept its
appointment by a written assumption in a form acceptable to Indenture Trustee.
In the event that a Successor Servicer has not been appointed and accepted its
appointment at the time when Servicer ceases to act as Servicer, Indenture
Trustee without further action shall automatically be appointed the Successor
Servicer. Indenture Trustee may


                                       13
<PAGE>   18


resign as Servicer by giving written notice of such resignation to Issuer and in
such event will be released from such duties and obligations, such release not
to be effective until the date a new servicer enters into a servicing agreement
with Issuer as provided below. Upon delivery of any such notice to Issuer,
Issuer shall obtain a new servicer as the Successor Servicer under the Sale and
Servicing Agreement. Any Successor Servicer other than 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
loans and (ii) enter into a servicing agreement with Issuer having substantially
the same provisions as the provisions of the Sale and Servicing Agreement
applicable to Servicer. If within 30 days after the delivery of the notice
referred to above, Issuer shall not have obtained such a new servicer, Indenture
Trustee may appoint, or may petition a court of competent jurisdiction to
appoint, a Successor Servicer. In connection with any such appointment,
Indenture Trustee may make such arrangements for the compensation of such
successor as it and such successor shall agree, subject to the limitations set
forth below and in the Sale and Servicing Agreement, and in accordance with
Section 8.2 of the Sale and Servicing Agreement, Issuer shall enter into an
agreement with such successor for the servicing of the Receivables (such
agreement to be in form and substance satisfactory to Indenture Trustee). If
Indenture Trustee shall succeed to Servicer's duties as servicer of the
Receivables as provided herein, it shall do so in its individual capacity and
not in its capacity as Indenture Trustee and, accordingly, the provisions of
Article VI shall be inapplicable to Indenture Trustee in its duties as the
successor to Servicer and the servicing of the Receivables. In case Indenture
Trustee shall become successor to Servicer under the Sale and Servicing
Agreement, Indenture Trustee shall be entitled to appoint as Servicer any one of
its Affiliates, or delegate any of its responsibilities as Servicer to agents,
subject to the terms of the Sale and Servicing Agreement, provided that such
appointment or delegation shall not affect or alter in any way the liability of
Indenture Trustee as a successor for the performance of the duties and
obligations of Servicer in accordance with the terms hereof.

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

                  (g) Without derogating from the absolute nature of the
assignment granted to Indenture Trustee under this Indenture or the rights of
Indenture Trustee hereunder, Issuer agrees that, unless such action is
specifically permitted hereunder or under the Basic Documents, it will not,
without the prior written consent of Indenture Trustee or the Holders of at
least a majority in Outstanding Amount of the Notes, amend, modify, waive,
supplement, terminate or surrender, or agree to any amendment, modification,
supplement, termination, waiver or surrender of, the terms of any Collateral or
the Basic Documents, or waive timely performance or observance by Servicer or
Seller under the Sale and Servicing Agreement; provided that no such amendment
shall (i) except for amendments and modifications of the Receivables permitted
under the Sale and Servicing Agreement, increase or reduce in any manner the
amount of, or accelerate or delay the timing of, distributions that are required
to be made for the benefit of the Noteholders, or (ii) reduce the aforesaid
percentage of the Notes which are required to consent to any such amendment,
without the consent of the Holders of all the Outstanding Notes. If any such
amendment, modification, supplement or waiver shall be so consented to by
Indenture Trustee or


                                       14
<PAGE>   19


such Holders, Issuer agrees, promptly following a request by Indenture Trustee
to do so, to execute and deliver, in its own name and at its own expense, such
agreements, instruments, consents and other documents as Indenture Trustee may
deem necessary or appropriate in the circumstances.

                  SECTION 3.8 Negative Covenants. So long as any Notes are
Outstanding, Issuer shall not:

                  (a) except as expressly permitted by this Indenture or the
Basic Documents, sell, transfer, exchange or otherwise dispose of any of the
properties or assets of Issuer, including those included in the Trust Estate,
unless directed to do so by Indenture Trustee;

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

                  (c) dissolve or liquidate in whole or in part; or

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

                  SECTION 3.9 Annual Statement as to Compliance. Issuer will
deliver to Indenture Trustee, within 120 days after the end of each fiscal year

Officer's Certificate stating, as to the Authorized Officer signing such
Officer's Certificate, that:

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

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

                  SECTION 3.10 Issuer May Consolidate, Etc. Only on Certain
Terms. (a) Issuer shall not consolidate or merge with or into any other Person,

custodian, trustee, sequestrator or similar official of Issuer or for any
substantial part of the Trust Estate, or the making by Issuer of any general
assignment for the benefit of creditors, or the failure by Issuer generally to
pay its debts as such debts become due, or the taking of action by Issuer in
furtherance of any of the foregoing. Issuer shall deliver to Indenture Trustee,
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 would become an Event of Default under clause (c), its status and what
action Issuer is taking or proposes to take with respect thereto.

                  SECTION 5.2 Acceleration of Maturity; Rescission and
Annulment.

                  (a) If an Event of Default should occur and be continuing,
then and in every such case Indenture Trustee or the Holders of Notes
representing not less than a majority of the Outstanding Amount of the Notes may
declare all the Notes to be immediately due and payable, by a notice in writing
to Issuer (and to Indenture Trustee if given by Noteholders), 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.

                  (b) 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 Indenture Trustee as hereinafter in this Article V
provided, the Holders of Notes representing a majority of the Outstanding Amount
of the Notes, by written notice to Issuer and Indenture Trustee, may rescind and
annul such declaration and its consequences if:

                  (i) Issuer has paid or deposited with 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; and

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

                           (C) 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.

                  SECTION 5.3 Collection of Indebtedness and Suits for
Enforcement by Indenture Trustee. (a) Issuer covenants that if (i) default is
made in the payment of any interest on any Note when the same becomes due and
payable, and such default continues for a period of five days, or (ii) default
is made in the payment of the principal of or any installment of the principal
of any Note when the same becomes due and payable, Issuer will, upon demand of
Indenture Trustee, pay to it, for the benefit of the Holders of the Notes, the
whole amount then due and payable on such Notes for principal and interest, with
interest upon the overdue principal, and, to the extent payment at such rate of
interest shall be legally enforceable, upon overdue installments of interest, at
the rate specified in Section 2.7 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 Indenture
Trustee and its agents and counsel.

                  (b) In case Issuer shall fail forthwith to pay such amounts
upon such demand, 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 Issuer or other obligor upon such Notes and collect
in the manner provided by law out of the property of Issuer or other obligor
upon such Notes, wherever situated, the moneys adjudged or decreed to be
payable.

                  (c) If an Event of Default occurs and is continuing, Indenture
Trustee may, as more particularly provided in Section 5.4, in its discretion,
proceed to protect and enforce its rights and the rights of the Noteholders, by
such appropriate proceedings as 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 Indenture Trustee by this Indenture or by law.

                  (d) In case there shall be pending, relative to 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, liquidator, sequestrator or similar official shall have been
appointed for or taken possession of Issuer or its property or such other
obligor or Person, or in case of any other comparable judicial proceedings
relative to Issuer or other obligor upon the Notes, or to the creditors or
property of Issuer or such other obligor, 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 Indenture Trustee shall
have made any demand pursuant to the provisions of this Section, Indenture
Trustee shall be entitled and empowered, by intervention in such proceedings or
otherwise:

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


                                       22
<PAGE>   27


         Indenture Trustee and each predecessor Indenture Trustee, except as a
         result of negligence, bad faith or willful misconduct) and of the
         Noteholders allowed in such proceedings;

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

                  (iii) to collect and receive any moneys 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 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 Indenture Trustee or the Holders of Notes allowed in any judicial
         proceedings relative to 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 Indenture Trustee, and, in the event that Indenture Trustee shall
consent to the making of payments directly to such Noteholders, to pay to
Indenture Trustee such amounts as shall be sufficient to cover reasonable
compensation to 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 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
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 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 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 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 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 Indenture Trustee (and also
any proceedings involving the interpretation of any provision of this Indenture
to which Indenture Trustee shall be a party), 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.


                                       23
<PAGE>   28


                  SECTION 5.4 Remedies; Priorities. (a) If an Event of Default
shall have occurred and be continuing, Indenture Trustee may do one or more of
the following (subject to Section 5.5):

                  (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 under this Indenture with respect thereto, whether by
         declaration or otherwise, enforce any judgment obtained, and collect
         from Issuer and any other obligor upon such Notes moneys 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 take any other appropriate action to protect and enforce the rights
         and remedies of Indenture Trustee and the Holders of the Notes; 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 that Indenture Trustee may not sell or otherwise liquidate the Trust
Estate following an Event of Default, other than an Event of Default described
in Section 5.1(a) or (b), unless (A) the Holders of 100% of the Outstanding
Amount of the Notes and Certificates consent thereto, (B) the proceeds of such
sale or liquidation distributable to the Noteholders and Certificateholders are
sufficient to discharge in full all amounts then due and unpaid upon such Notes
and Certificates for principal and interest or (C) 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 they would have become due
if the Notes had not been declared due and payable, and Indenture Trustee
obtains the consent of Holders of 66-2/3% of the Outstanding Amount of the
Notes. In determining such sufficiency or insufficiency with respect to clause
(B) and (C), 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 Indenture Trustee collects any money or property
pursuant to this Article V, it shall pay out such money or property (and other
amounts including amounts held on deposit in the Reserve Account) held as
Collateral for the benefit of the Noteholders in the following order:

                  FIRST: to Indenture Trustee for amounts due under Section 6.7;

                  SECOND: to Servicer for due and unpaid Servicing Fees;

                  THIRD: to Noteholders for amounts due and unpaid on the Notes
for principal and interest, ratably, without preference or priority of any kind,
according to the amounts due and payable on the Notes for interest;

                  FOURTH: to Noteholders for amounts due and unpaid on the Notes
for principal, ratably, without preference or priority of any kind, according to
the amounts due and payable on the Notes for principal; and


                                       24
<PAGE>   29


                  FIFTH: to Issuer for distribution to the
Certificateholders.

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

                  SECTION 5.5 Optional Preservation of the Receivables. If the
Notes have been declared to be due and payable under Section 5.2 following an
Event of Default and such declaration and its consequences have not been
rescinded and annulled, Indenture Trustee may, but need not, elect to maintain
possession of the Trust Estate. 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 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
Estate, 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 5.6 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:

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

                  (b) the Holders of not less than 25% of the Outstanding Amount
of the Notes have made written request to Indenture Trustee to institute such
proceeding in respect of such Event of Default in its own name as Indenture
Trustee hereunder;

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

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

                  (e) no direction inconsistent with such written request has
been given to Indenture Trustee during such 60-day period by the Holders of a
majority of the Outstanding Amount of the Notes;

it being 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.

<PAGE>   30


                  In the event Indenture Trustee shall receive conflicting or
inconsistent requests and indemnity from two or more groups of Holders of Notes,
each representing less than a majority of the Outstanding Amount of the Notes,
Indenture Trustee in its sole discretion may determine what action, if any,
shall be taken, notwithstanding any other provisions of this Indenture.

                  SECTION 5.7 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
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 5.8 Restoration of Rights and Remedies. If Indenture
Trustee 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 Indenture Trustee
or to such Noteholder, then and in every such case Issuer, 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 Indenture Trustee and the Noteholders
shall continue as though no such Proceeding had been instituted.

                  SECTION 5.9 Rights and Remedies Cumulative. No right or remedy
herein conferred upon or reserved to Indenture Trustee 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 Indenture Trustee 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 V or by law
to Indenture Trustee or to the Noteholders may be exercised from time to time,
and as often as may be deemed expedient, by Indenture Trustee or by the
Noteholders, as the case may be.

                  SECTION 5.11 Control by Noteholders. The Holders of a majority
of the Outstanding Amount of the Notes shall have the right to direct the time,
method and place of conducting any proceeding for any remedy available to
Indenture Trustee with respect to the Notes or exercising any trust or power
conferred on Indenture Trustee; provided that

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


                                       26
<PAGE>   31


                  (b) subject to the express terms of Section 5.4, any direction
to Indenture Trustee to sell or liquidate the Trust Estate shall be by the
Holders of Notes representing not less than 100% of the Outstanding Amount of
the Notes;

                  (c) if the conditions set forth in Section 5.5 have been
satisfied and Indenture Trustee elects to retain the Trust Estate pursuant to
such Section, then any direction to Indenture Trustee by Holders of Notes
representing less than 100% of the Outstanding Amount of the Notes to sell or
liquidate the Trust Estate shall be of no force and effect;

                  (d) Indenture Trustee may take any other action deemed proper
by Indenture Trustee that is not inconsistent with such direction; and

                  (e) such direction shall be in writing; provided, further,
that, subject to Section 6.1, Indenture Trustee need not take any action that it
determines might involve it in liability 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 5.2, the
Holders of Notes of not less than a majority of the Outstanding Amount of the
Notes may waive any past Default or Event of Default and its consequences except
a Default (a) in payment of principal of or interest on any of the Notes or (b)
in respect of a covenant or provision hereof which cannot be modified or amended
without the consent of the Holder of each Note. In the case of any such waiver,
Issuer, Indenture Trustee and the Holders of the Notes shall be restored to
their former positions and rights hereunder, respectively; but no such waiver
shall extend to any subsequent or other Default or impair any right consequent
thereto.

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

                  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 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 (a) any suit instituted by
Indenture Trustee, (b) any suit instituted by any Noteholder, or group of
Noteholders, in each case holding in the aggregate more than 10% of the
Outstanding Amount of the Notes or (c) 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).

<PAGE>   32


                  SECTION 5.14 Waiver of Stay or Extension Laws. 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 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
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. Indenture Trustee's right to
seek and recover judgment on the Notes or under this Indenture shall not be
affected by the seeking, obtaining or application of any other relief under or
with respect to this Indenture. Neither the lien of this Indenture nor any
rights or remedies of Indenture Trustee or the Noteholders shall be impaired by
the recovery of any judgment by Indenture Trustee against 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 Issuer.

                  SECTION 5.16 Performance and Enforcement of Certain
Obligations. (a) Promptly following a request from Indenture Trustee to do so
and at Administrator's expense, Issuer agrees to take all such lawful action as
Indenture Trustee may request to compel or secure the performance and observance
by Seller and Servicer, as applicable, of each of their obligations to Issuer
under or in connection with the Sale and Servicing Agreement or by the Seller or
any Seller Affiliate, as applicable, of each of their obligations under or in
connection with each Purchase Agreement, in each case, in accordance with the
terms thereof, and to exercise any and all rights, remedies, powers and
privileges lawfully available to Issuer under or in connection with the Sale and
Servicing Agreement and each Purchase Agreement, as the case may be, to the
extent and in the manner directed by Indenture Trustee, including the
transmission of notices of default on the part of Seller, Servicer or applicable
Seller Affiliate thereunder and the institution of legal or administrative
actions or proceedings to compel or secure performance by Seller or Servicer of
each of their obligations under the Sale and Servicing Agreement or by the
Seller or any Seller Affiliate, as applicable, of each of their obligations
under or in connection with each Purchase Agreement.

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

                         ARTICLE VI INDENTURE TRUSTEE.

                  SECTION 6.1 Duties of Indenture Trustee. (a) If an Event of
Default has occurred and is continuing, of which a Responsible Officer of
Indenture Trustee has actual knowledge, 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.

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

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

                  (ii) in the absence of bad faith on its part, 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 Indenture Trustee and conforming to the
         requirements of this Indenture; however, Indenture Trustee shall
         examine the certificates and opinions to determine whether or not they
         conform to the requirements of this Indenture.

                  (c) Indenture Trustee may not be relieved from liability for

                  (ii) Indenture Trustee shall not be liable for any error of

repayment of such funds or indemnity satisfactory to it against such risk or
liability is not assured to it.

                  (g) Every provision of this Indenture relating to the conduct

                  (b) Before Indenture Trustee acts or refrains from acting, it
may require an Officer's Certificate or an Opinion of Counsel. Indenture Trustee

                  (c) Indenture Trustee may execute any of the trusts or powers
hereunder or perform any duties hereunder either directly or by or through

                  (d) 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, that Indenture Trustee's conduct does not
constitute wilful misconduct, negligence or bad faith.

                  (e) 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.

                  SECTION 6.3 Individual Rights of Indenture Trustee. Indenture
Trustee in its individual or any other capacity may become the owner or pledgee
of Notes and may otherwise deal with Issuer or its Affiliates with the same

                  SECTION 6.5 Notice of Defaults. If a Default occurs and is
continuing and if it is either actually known or written notice of the existence
thereof has been delivered to a Responsible Officer of Indenture Trustee,
Indenture Trustee shall mail to each Noteholder notice of the Default within 90
days after such knowledge or notice 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), 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 6.6 Reports by Indenture Trustee to Holders. Indenture
Trustee shall deliver to each Noteholder such information as may be reasonably
required to enable such Holder to prepare its Federal and state income tax
returns.

                  SECTION 6.7 Compensation and Indemnity. (a) The compensation
and reimbursement of expenses of Indenture Trustee shall be governed by the
Administration Agreement. In addition, Issuer shall reimburse any expenses
incurred by the Indenture Trustee in pursuing remedies pursuant to Section 5.4.
Issuer has caused Administrator to agree to indemnify Indenture Trustee and its
officers, directors, employees and agents against any and all loss, liability or
expense (including attorneys' fees and expenses) incurred by it in connection
with the acceptance or the administration of this trust and the performance of
its duties hereunder. Neither Issuer nor Administrator need reimburse any
expense or indemnify against any loss, liability or expense incurred by
Indenture Trustee through Indenture Trustee's own wilful misconduct, negligence
or bad faith or to the extent arising from the breach by the Indenture Trustee
of any of its representations and warranties and covenants set forth herein.

                  (b) Issuer's payment obligations to Indenture Trustee pursuant
to this Section and the Administration Agreement referenced in the preceding
paragraph shall survive the discharge of this Indenture subject to a
satisfaction of the Rating Agency Condition. When Indenture Trustee incurs
expenses after the occurrence of a Default specified in Section 5.1(d) or (e)
with respect to Issuer, the expenses are intended to constitute expenses of
administration under Title 11 of the United States Code or any other applicable
Federal or state bankruptcy, insolvency or similar law.

                  SECTION 6.8 Replacement of Indenture Trustee. (a) Indenture
Trustee may resign at any time by so notifying Issuer. The Holders of a majority
in Outstanding Amount of the Notes may remove Indenture Trustee by so notifying
Indenture Trustee and may appoint a successor Indenture Trustee. Issuer shall
remove Indenture Trustee if:

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

                  (ii) Indenture Trustee is adjudged a bankrupt or insolvent;

                  (iii) a receiver or other public officer takes charge of
         Indenture Trustee or its property; or

                  (iv) Indenture Trustee otherwise becomes incapable of acting.

<PAGE>   36


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

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

                  (d) 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, Issuer or the Holders of a majority in Outstanding
Amount of the Notes may petition any court of competent jurisdiction for the
appointment of a successor Indenture Trustee.

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

                  (f) Any resignation or removal of Indenture Trustee and
appointment of a Successor Indenture Trustee pursuant to any of the provisions
of this Section shall not become effective until acceptance of appointment by
the successor Indenture Trustee pursuant to this Section 6.8 and payment of all
fees and expenses owed to the outgoing Indenture Trustee.

                  (g) Notwithstanding the resignation or removal of Indenture
Trustee pursuant to this Section, Issuer's and Administrator's obligations under
Section 6.7 shall continue for the benefit of the retiring Indenture Trustee.

                  (h) Indenture Trustee shall not be liable for the acts or
omissions of any successor Indenture Trustee.

                  SECTION 6.9 Successor Indenture Trustee by Merger. (a) If
Indenture Trustee consolidates with, merges or converts into, or transfers all
or substantially all its corporate trust business or assets to, another
corporation or banking association, the resulting, surviving or transferee
corporation without any further act shall be the successor Indenture Trustee.
Indenture Trustee shall provide the Rating Agencies and the Administrator prior
written notice of any such transaction.

                  (b) In case at the time such successor or successors by
merger, conversion or consolidation to 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 Indenture Trustee may adopt the
certificate of authentication of any predecessor trustee, and deliver such Notes
so authenticated; and in case at that time any of the Notes shall not have been
authenticated, any successor to Indenture Trustee may authenticate such Notes
either in the name of any 39 predecessor hereunder or in the name of the
successor to Indenture Trustee; and in all such cases


                                       32
<PAGE>   37


such certificates shall have the full force which it is anywhere in the Notes or
in this Indenture provided that the certificate of Indenture Trustee shall have.

                  SECTION 6.10 Appointment of Co-Indenture Trustee or Separate
Indenture Trustee. (a) Notwithstanding any other provisions of this Indenture,
at any time, after delivering written notice to the Administrator, for the
purpose of meeting any legal requirement of any jurisdiction in which any part
of Issuer may at the time be located, Indenture Trustee shall have the power and
may execute and deliver all instruments to appoint one or more Persons to act as
a co-trustee or co-trustees, or separate trustee or separate trustees, of all or
any part of the Trust, and to vest in such Person or Persons, in such capacity
and for the benefit of the Noteholders, such title to the Trust, or any part
hereof, and, subject to the other provisions of this Section, such powers,
duties, obligations, rights and trusts as Indenture Trustee may consider
necessary or desirable. No co-trustee or separate trustee hereunder shall be
required to meet the terms of eligibility as a successor 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 6.8.

                  (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 Indenture Trustee shall be conferred or imposed upon and
         exercised or performed by 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 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 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 Issuer 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 Indenture Trustee;

                  (ii) no trustee hereunder shall be personally liable by reason

         of or remove any separate trustee or co-trustee.

                  (c) Any notice, request or other writing given to 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 Agreement and
the conditions of this Article VI. 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

provisions of this Indenture, specifically including every provision of this
Indenture relating to the conduct of, affecting the liability of, or affording
protection to, Indenture Trustee. Every such instrument shall be filed with

constitute 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 Agreement 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 invest in and be
exercised by Indenture Trustee, to the extent permitted by law, without the
appointment of a new or successor trustee.

         Account shall be applied to the payment of principal on the Class A-1
         Notes on a pro rata basis; and

                  (iii) payment of principal to the Holders of the Class A-2

investment or the proceeds of such sale, in either case without any further
action by any Person, and, in connection with any direction to Indenture Trustee
to make any such investment or sale, if requested by Indenture Trustee, Issuer
shall deliver to Indenture Trustee an Opinion of Counsel, acceptable to
Indenture Trustee, to such effect.

                  (b) Subject to Section 6.1(c), Indenture Trustee shall not in
any way be held liable by reason of any insufficiency in any of the Trust
Accounts resulting from any loss on any Eligible Investment included therein
except for losses attributable to Indenture Trustee's failure to make payments
on such Eligible Investments issued by Indenture Trustee, in its commercial
capacity as principal obligor and not as trustee, in accordance with their
terms.

                  (c) If (i) Issuer shall have failed to give investment
directions for any funds on deposit in the Trust Accounts to Indenture Trustee
by 11:00 a.m. Eastern Time (or such other time as may be agreed by Issuer and

         questions arising under this Indenture or in any supplemental
         indenture; provided that such action shall not materially and 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 VI;

                  (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; or (viii) (A)
         to add, modify or eliminate such provisions of the Indenture as may be
         necessary or advisable in order to enable all or a portion of Issuer to
         qualify as, and to permit an election to be made to cause all or a
         portion of Issuer to be treated as, a "financial asset securitization
         investment trust" as described in the provisions of the "Small Business
         Job Protection Act of 1996," or to enable all or a portion of the
         Issuer to qualify and an election to be made for similar treatment
         under such comparable subsequent federal income tax provisions as may
         ultimately be enacted into law, and (B) in connection with any such
         election, to modify or eliminate existing provisions set forth in this
         Indenture relating to the intended federal income tax treatment of the
         Notes or Certificates and Issuer in the absence of the election; it
         being a condition to any such amendment that each Rating Agency will
         have notified the Indenture Trustee in writing that the amendment will
         not result in a reduction or withdrawal of the rating of any
         outstanding Notes or Certificates with respect to which it is a Rating
         Agency; and

                  (viii) to add, modify or eliminate such provisions as may be
         necessary or advisable in order to enable (a) the transfer to Issuer of
         all or any portion of the Receivables to be derecognized under GAAP by
         Seller to Issuer, (b) Issuer to avoid becoming a member of Seller's
         consolidated group under GAAP or (c) the Seller, any Seller Affiliate
         or any of other Affiliates to otherwise comply with or obtain more
         favorable treatment under any law or regulation or any accounting rule
         or principle; it being a condition to any such amendment that each
         Rating Agency will have notified the Indenture Trustee in writing that
         the amendment will not result in a reduction or withdrawal of the
         rating of any outstanding Notes or Certificates with respect to which
         it is a Rating Agency.

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.

Order, may, also without the consent of any of the Holders of the Notes but with
prior notice to the Rating Agencies by Issuer, as evidenced to Indenture
Trustee, enter into an indenture or indentures supplemental hereto for the
purpose of adding any provisions to, or changing in any manner or eliminating
any of the provisions of, this Indenture or of modifying in any manner the

<PAGE>   44


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

                  SECTION 9.2 Supplemental Indentures with Consent of
Noteholders.

                  (a) Issuer and Indenture Trustee, when authorized by an Issuer
Order, also may, with prior notice to the Rating Agencies and with the consent
of the Holders of not less than a majority of the Outstanding Amount of the
Notes, by Act of such Holders delivered to Issuer and Indenture Trustee, enter
into an indenture or indentures supplemental hereto for the purpose of adding
any provisions to, or changing in any manner or eliminating any of the
provisions of, this Indenture or of modifying in any manner the rights of the
Holders of the Notes under this Indenture; provided 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 provision 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 V, 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 Outstanding Amount of the
         Notes, the consent of the Holders of which is required for any such
         supplemental indenture, or the consent of the Holders of which is
         required for any waiver of compliance with certain provisions of this
         Indenture or certain defaults hereunder and their consequences provided
         for in this Indenture;

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

                  (iv) reduce the percentage of the Outstanding Amount of the

                  (v) modify any provision of this Section except to increase
         any percentage specified herein or to 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 Payment Date (including
         the calculation of any of the individual components of such


                                       40
<PAGE>   45


         calculation) or to 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
         or in the Basic Documents, 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.

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

                  (c) 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.

                  (d) Promptly after the execution by Issuer and Indenture
Trustee of any supplemental indenture pursuant to this Section, 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 Indenture Trustee to
mail such notice, or any defect therein, shall not, however, in any way impair
or affect the validity of any such supplemental indenture.

                  SECTION 9.3 Execution of Supplemental Indentures. In
executing, or permitting the additional trusts created by, any supplemental
indenture permitted by this Article IX or the modifications thereby of the
trusts created by this Indenture, Indenture Trustee shall be entitled to
receive, and subject to Sections 6.1 and 6.2, 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. Indenture
Trustee may, but shall not be obligated to, enter into any such supplemental
indenture that affects Indenture Trustee's own rights, duties, liabilities or
immunities under this Indenture or otherwise.

                  SECTION 9.4 Effect of Supplemental Indenture. Upon the
execution of any supplemental indenture pursuant to the provisions hereof, this
Indenture shall be and be deemed to be modified and amended in accordance
therewith with respect to the Notes affected thereby, and the respective rights,
limitations of rights, obligations, duties, liabilities and immunities under
this Indenture of Indenture Trustee, Issuer and the Holders of the Notes shall
thereafter be determined, exercised and enforced hereunder subject in all
respects to such modifications and amendments, and all the terms and conditions
of any such supplemental indenture shall be and be deemed to be part of the
terms and conditions of this Indenture for any and all purposes.

                  SECTION 9.5 Conformity With Trust Indenture Act. Every
amendment of this Indenture and every supplemental indenture executed pursuant
to this Article IX shall conform to the requirements of the Trust Indenture Act
as then in effect so long as this Indenture shall then be qualified under the
Trust Indenture Act.

                  SECTION 9.6 Reference in Notes to Supplemental Indentures.
Notes authenticated and delivered after the execution of any supplemental
indenture pursuant to this Article IX may, and if required by Indenture Trustee
shall, bear a notation in form approved by Indenture Trustee as to any matter
provided for in such supplemental indenture. If Issuer or Indenture Trustee
shall so determine, new Notes so modified as to conform, in the opinion of
Indenture Trustee and Issuer, to any such supplemental indenture may be prepared
and executed by Issuer and authenticated and delivered by Indenture Trustee in
exchange for Outstanding Notes.

                         ARTICLE X REDEMPTION OF NOTES.

                  SECTION 10.1 Redemption. (a) The Class A-2 Notes are subject
to redemption in whole, but not in part, at the direction of Seller or Servicer
pursuant to Section 9.1(a) of the Sale and Servicing Agreement, on any Payment
Date on which Seller or Servicer exercises its option to purchase the Trust
Estate pursuant to said Section 9.1(a), for a purchase price equal to the
Redemption Price; provided that Issuer has available funds sufficient to pay the
Redemption Price. Servicer or Issuer shall furnish the Rating Agencies notice of
such redemption. If the Class A-2 Notes are to be redeemed pursuant to this
Section 10.1(a), Servicer or Issuer shall furnish notice of such election to
Indenture Trustee not later than 25 days prior to the Redemption Date and Issuer
shall deposit with Indenture Trustee in the Note Distribution Account the
Redemption Price of the Class A-2 Notes to be redeemed whereupon all such Class
A-2 Notes shall be due and payable on the Redemption Date upon the furnishing of
a notice complying with Section 10.2 to each Holder of the Class A-2 Notes.

                  (b) If the assets of Issuer are sold pursuant to Section 9.2
of the Trust Agreement, all amounts on deposit in the Note Distribution Account
shall be paid to the Noteholders up to the Outstanding Amount of the Notes and
all accrued and unpaid interest thereon. If amounts are to be paid to
Noteholders pursuant to this Section 10.1(b), Servicer or Issuer shall, to the
extent practicable, furnish notice of such event to Indenture Trustee not later
than 25 days prior to the Redemption Date whereupon all such amounts shall be
payable on the Redemption Date.

                  SECTION 10.2 Form of Redemption Notice. (a) Notice of
redemption under Section 10.1(a) shall be given by Indenture Trustee by
facsimile or by first-class mail, postage prepaid, transmitted or mailed prior
to the applicable Redemption Date to each Holder of Class A-2 Notes, as of the
close of business on the Record Date preceding the applicable Redemption Date,
at such Holder's address appearing in the Note Register.

                  All notices of redemption shall state:

                  (i) the Redemption Date;

                  (ii) the Redemption Price;

                  (iii) that the Record Date otherwise applicable to such
         Redemption Date is not applicable and that payments shall be made only
         upon presentation and surrender of such Class A-2 Notes and the place
         where such Class A-2 Notes are to be surrendered for


                                       42
<PAGE>   47


         payment of the Redemption Price (which shall be the office or agency of
         Issuer to be maintained as provided in Section 3.2); and

                  (iv) that interest on the Class A-2 Notes shall cease to
         accrue on the Redemption Date.

Notice of redemption of the Class A-2 Notes shall be given by Indenture Trustee
in the name and at the expense of Issuer. Failure to give notice of redemption,
or any defect therein, to any Holder of any Class A-2 Note shall not impair or
affect the validity of the redemption of any other Class A-2 Note.

                  (b) Prior notice of redemption under Section 10.1(b) is not
required to be given to Noteholders.

                  SECTION 10.3 Notes Payable on Redemption Date. The Class A-2
Notes to be redeemed shall, following notice of redemption as required by
Section 10.2 (in the case of redemption pursuant to Section 10.1(a)), on the
Redemption Date become due and payable at the Redemption Price and (unless
Issuer shall default in the payment of the Redemption Price) no interest shall
accrue on the Redemption Price for any period after the date to which accrued
interest is calculated for purposes of calculating the Redemption Price.

                           ARTICLE XI MISCELLANEOUS.

                  SECTION 11.1 Compliance Certificates and Opinions, etc. (a)
Upon any application or request by Issuer to Indenture Trustee to take any

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 such 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


                                       43
<PAGE>   48


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

                  (b) Prior to the deposit of any Collateral or other property
or securities with Indenture Trustee that is to be made the basis for the
release of any property or securities subject to the lien of this Indenture,
Issuer shall, in addition to any obligation imposed in Section 11.1(a) or
elsewhere in this Indenture, furnish to 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 Issuer of
the Collateral or other property or securities to be so deposited.

                  (i) Whenever Issuer is required to furnish to Indenture
         Trustee an Officer's Certificate certifying or stating the opinion of
         any signer thereof as to the matters described in clause (i), Issuer
         shall also deliver to Indenture Trustee an Independent Certificate as
         to the same matters, if the fair value to Issuer of the 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 Issuer, as set forth in the certificates delivered
         pursuant to clause (i) and this clause (ii), is 10% or more of the
         Outstanding Amount of the Notes, but such a certificate need not be
         furnished with respect to any securities so deposited, if the fair
         value thereof to Issuer as set forth in the related Officer's
         Certificate is less than $25,000 or less than one percent of the
         Outstanding Amount of the Notes.

                  (ii) Other than with respect to the release of any Purchased
         Receivables or Defaulted Receivables, whenever any property or
         securities are to be released from the lien of this Indenture, Issuer
         shall also furnish to 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.

                  (iii) Whenever Issuer is required to furnish to Indenture
         Trustee an Officer's Certificate certifying or stating the opinion of
         any signer thereof as to the matters described in clause (iii), Issuer
         shall also furnish to 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 Purchased Receivables and Defaulted
         Receivables, or securities 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) and this clause (iv),
         equals 10% or more of the Outstanding Amount of the Notes, 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 Outstanding Amount of the Notes.

                  (iv) Notwithstanding Section 2.9 or any other provision of
         this Section, Issuer may (A) collect, liquidate, sell or otherwise
         dispose of Receivables as and to the extent permitted or required by
         the Basic Documents and (B) make cash payments out of the Trust
         Accounts as and to the extent permitted or required by the Basic
         Documents.

                  SECTION 11.2 Form of Documents Delivered to Indenture Trustee.

                  (a) 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.

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

                  (c) 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.

                  (d) Whenever in this Indenture, in connection with any
application or certificate or report to Indenture Trustee, it is provided that
Issuer shall deliver any document as a condition of the granting of such
application, or as evidence of 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 Issuer to have such application granted or
to the sufficiency of such certificate or report. The foregoing shall not,
however, be construed to affect 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 VI.

                  SECTION 11.3 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 Indenture Trustee, and, where it is
hereby expressly required, to 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


                                       45
<PAGE>   50


Section 6.1) conclusive in favor of Indenture Trustee and 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 customary manner of Indenture
Trustee.

                  (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
Indenture Trustee or Issuer in reliance thereon, whether or not notation of such
action is made upon such Note.

                  SECTION 11.4 Notices, etc., to Indenture Trustee, Issuer and
Rating Agencies. Any request, demand, authorization, direction, notice, consent,
waiver or Act of Noteholders or other documents provided or permitted by this
Indenture to be made upon, given or furnished to or filed with:

                  (a) Indenture Trustee by any Noteholder, Administrator or
Issuer shall be sufficient for every purpose hereunder if personally delivered,
delivered by overnight courier or mailed certified mail, return receipt
requested and shall be deemed to have been duly given upon receipt to Indenture
Trustee at its Corporate Trust Office, or

                  (b) Issuer by Indenture Trustee or by any Noteholder shall be
sufficient for every purpose hereunder if personally delivered, delivered by
overnight courier or mailed certified mail, return receipt requested and shall
be deemed to have been duly given upon receipt to Issuer addressed to: Wells
Fargo Auto Trust 200__-__, in care of _____________________, with a copy to
Administrator at Wells Fargo Bank, N.A., 420 Montgomery Street, San Francisco,
California 94163, Attention: ______________, or at any other address previously
furnished in writing to Indenture Trustee by Issuer or Administrator. Issuer
shall promptly transmit any notice received by it from the Noteholders to
Indenture Trustee.

                  Notices required to be given to the Rating Agencies by Issuer,
Indenture Trustee or Owner Trustee shall be in writing, personally delivered,
delivered by overnight courier or mailed certified mail, return receipt
requested to (i) in the 56 case of Moody's, at the following address: Moody's
Investors Service, Inc., 99 Church Street, New York, New York 10004, (ii) in the
case of S&P, at the following address: Standard & Poor's Ratings Services, 26
Broadway (15th Floor), New York, New York 10004, Attention of Asset Backed
Surveillance Department; and (iii) in the case of Fitch, at the following
address: Fitch Investors Service, L.P., One State Street Plaza, New York, New
York 10004 or as to each of the foregoing, at such other address as shall be
designated by written notice to the other parties.

                  SECTION 11.5 Notices to Noteholders; Waiver.

                  (a) Where this Indenture provides for notice to Noteholders of
any event, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if in writing and mailed, first-class, postage prepaid to
each Noteholder affected by such event, at his address as it


                                       46
<PAGE>   51


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.

                  (b) 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
Indenture Trustee but such filing shall not be a condition precedent to the
validity of any action taken in reliance upon such a waiver.

                  (c) 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 Indenture Trustee shall
be deemed to be a sufficient giving of such notice.

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

                  SECTION 11.6 Alternate Payment and Notice Provisions.
Notwithstanding any provision of this Indenture or any of the Notes to the
contrary, Issuer may enter into any agreement with any Holder of a Note
providing for a method of payment, or notice by 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, provided that such methods are
reasonable and consented to by Indenture Trustee (which consent shall not be
unreasonably withheld). Issuer will furnish to the trustee a copy of each such
agreement and Indenture Trustee will cause payments to be made and notices to be
given in accordance with such agreements.

                  SECTION 11.7 Conflict with Trust Indenture Act. If any
provision hereof limits, qualifies or conflicts with another provision hereof
that is required to be included in this indenture by any of the provisions of
the Trust Indenture Act, such required provision shall control. The provisions
of TIA Sections 310 through 317 that impose duties on any person (including the
provisions automatically deemed included herein unless expressly excluded by
this Indenture) are a part of and govern this Indenture, whether or not
physically contained herein.

                  SECTION 11.8 Effect of Headings and Table of Contents. The
Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.

                  SECTION 11.9 Successors and Assigns. All covenants and
agreements in this Indenture and the Notes by Issuer shall bind its successors
and assigns, whether so expressed or not. All agreements of Indenture Trustee in
this Indenture shall bind its successors.


                                       47
<PAGE>   52


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

                  SECTION 11.11 Benefits of Indenture. Nothing in this Indenture
or in the Notes, express or implied, shall give to any Person, other than the
parties hereto and their successors hereunder, and the Noteholders, and any
other party secured hereunder, and any other person with an ownership interest
in any part of the Trust Estate, any benefit or any legal or equitable right,
remedy or claim under this Indenture.

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

                  SECTION 11.13 GOVERNING LAW. THIS INDENTURE SHALL BE CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, INCLUDING SECTION 5-1401
OF THE GENERAL OBLIGATIONS LAW, WITHOUT REFERENCE TO ITS CONFLICT OF LAW
PROVISIONS, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER
SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

                  SECTION 11.14 Counterparts. This Indenture may be executed in
any number of counterparts, each of which so executed shall be deemed to be an
original, but all such counterparts shall together constitute but one and the
same instrument.

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

                  SECTION 11.16 Trust Obligation. No recourse may be taken,
directly or indirectly, with respect to the obligations of Issuer, Seller,
Servicer, Owner Trustee or Indenture Trustee on the Notes or under this
Indenture or any certificate or other writing delivered in connection herewith
or therewith, against (i) Seller, Servicer, Indenture Trustee or Owner Trustee
in its individual capacity, (ii) any owner of a beneficial interest in Issuer or
(iii) any partner, owner, beneficiary, agent, officer, director, employee or
agent of Seller, Servicer, Indenture Trustee or Owner Trustee in its individual
capacity, any holder of a beneficial interest in Issuer, Seller, Servicer, Owner
Trustee or Indenture Trustee or of any successor or assign of Seller, Servicer,
Indenture Trustee or Owner Trustee in its individual capacity, except as any
such Person may have expressly agreed (it being understood that Indenture
Trustee and 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


                                       48
<PAGE>   53


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 Issuer hereunder,
Owner Trustee shall be subject to, and entitled to the benefits of, the terms
and provisions of Article VI, VII and VIII of the Trust Agreement.

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

                  SECTION 11.18 Inspection. Issuer agrees that, on reasonable
prior notice, it will permit any representative of Indenture Trustee, during
Issuer's normal business hours, to examine all the books of account, records,
reports, and other papers of Issuer, to make copies and extracts therefrom, to
cause such books to be audited by Independent certified public accountants, and
to discuss Issuer's affairs, finances and accounts with Issuer's officers,
employees, and independent certified public accountants, all at such reasonable
times and as often as may be reasonably requested. 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 Indenture Trustee may reasonably determine that such disclosure is
consistent with its obligations hereunder.

                  Unless this Note is presented by an authorized representative
of The Depository Trust Company, a New York corporation ("DTC"), to the Issuer
or its agent for registration of transfer, exchange or payment, and any Note
issued is registered in the name of Cede & Co. or in such other name as is

hereof, Cede & Co., has an interest herein.

                  THE PRINCIPAL OF THIS NOTE IS PAYABLE IN INSTALLMENTS AS SET

                       _____% CLASS A-1 ASSET BACKED NOTES

                  Wells Fargo Auto Trust 200__-__, a New York common law trust
(including any successor, the "Issuer"), for value received, hereby promises to
pay to CEDE & CO., or registered assigns, the principal sum of
__________________ DOLLARS ($___________), partially payable on each Payment
Date in an amount equal to the result obtained by multiplying (i) a fraction the
numerator of which is the initial principal amount of this Note and the
denominator of which is the aggregate initial principal amount of the Class A-1
Notes (the "Fraction") by (ii) the aggregate amount, if any, payable from the
Note Distribution Account in respect of principal on the A-1 Notes pursuant to
Section 3.1 of the Indenture; provided that the entire unpaid principal amount
of this Note shall be due and payable on the earlier of the Final Scheduled
Payment Date for the Class A-1 Notes and the Redemption Date, if any, pursuant
to Section 10.1 of the Indenture. The Issuer will pay interest on this Note on
each Payment Date until the principal of this Note is paid or made available for
payment, in an amount equal to the product of the Class A-1 Noteholders'
Interest Distributable Amount for the related Payment Date multiplied by the
Fraction subject to certain limitations contained in Section 3.1 and Section 8.2
of the Indenture. Such principal of and interest on this Note shall be paid in
the manner specified in the Indenture.

                  The principal of and interest on this Note are payable in such
coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts. All payments made by the
Issuer with respect to this Note shall be applied first to interest due and
payable on this Note as provided above and then to the unpaid principal of this

Note. Reference is made to the further provisions of this Note set forth on the
reverse hereof, which shall have the same effect as though fully set forth on

executed by the Indenture Trustee by manual signature, this Note shall not be
entitled to any benefit under the Indenture referred to on the reverse hereof,
or be valid or obligatory for any purpose.

                  IN WITNESS WHEREOF, the Issuer has caused this instrument to

                                [REVERSE OF NOTE]

                  This Note is one of a duly authorized issue of Notes of the
Issuer, designated as its ______% Class A-1 Asset Backed Notes (herein called
the "A-1 Notes" or the "Notes"), all issued under an Indenture dated as of
__________, 200__ (such Indenture, as supplemented or amended, is herein called
the "Indenture"), between the Issuer and _____________________, not in its
individual capacity but solely as trustee (the "Indenture Trustee"), which term
includes any successor Indenture Trustee 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 Indenture
Trustee and the Holders of the Notes. The Notes are subject to all terms of the
Indenture. All terms used in this Note that are not otherwise defined herein and
that are defined in the Indenture shall have the meanings assigned to them in or
pursuant to the Indenture.

                  The Notes and the Class A-2 Notes are and will be equally and
ratably secured by the collateral pledged as security therefor as provided in
the Indenture.

                  The Issuer shall pay interest on overdue installments of
interest at the Class A-1 Interest Rate to the extent lawful.

                  Each Holder or Note Owner, by acceptance of a Note, or, in the

(including any successor, the "Issuer"), for value received, hereby promises to
pay to CEDE & CO., or registered assigns, the principal sum of
__________________ DOLLARS ($___________), partially payable on each Payment
Date in an amount equal to the result obtained by multiplying (i) a fraction the
numerator of which is the initial principal amount of this Note and the
denominator of which is the aggregate initial principal amount of the Class A-2
Notes ("the Fraction") by (ii) the aggregate amount, if any, payable from the
Note Distribution Account in respect of principal on the A-2 Notes pursuant to
Section 3.1 of the Indenture; provided that the entire unpaid principal amount
of this Note shall be due and payable on the earlier of the Final Scheduled
Payment Date for the Class A-2 Notes and the Redemption Date, if any, pursuant
to Section 10.1 of the Indenture. No payments of principal of the A-2 Notes will
be made until the principal of the A-1 Notes has been paid in full. The Issuer
will pay interest on this Note on each Payment Date until the principal of this
Note is paid or made available for payment in an amount equal to the product of
the Class A-2 Noteholders' Interest distributable Amount for the related
Transfer Date multiplied by the Fraction, subject to certain limitations
contained in Section 3.1 and Section 8.2 of the Indenture. Such principal of and
interest on this Note shall be paid in the manner specified in the Indenture.

                  The principal of and interest on this Note are payable in such
coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and

private debts. All payments made by the Issuer with respect to this Note shall
be applied first to interest due and payable on this Note as provided above and
then to the unpaid principal of this Note.

                  Reference is made to the further provisions of this Note set
forth on the reverse hereof, which shall have the same effect as though fully
set forth on the face of this Note. Unless the certificate of authentication
hereon has been executed by the Indenture Trustee by manual signature, this Note
shall not be entitled to any benefit under the Indenture referred to on the
reverse hereof, or be valid or obligatory for any purpose.
