authorized denominations. Until so exchanged, the temporary Notes shall in all
respects be entitled to the same benefits under this Indenture as Definitive
Notes.

        SECTION 2.04 Registration; Registration of Transfer and Exchange.

        (a) The Note Registrar shall maintain a Note Register in which, subject
to such reasonable regulations as it may prescribe, the Note Registrar shall
provide for the registration of Notes and transfers and exchanges of Notes as
provided in this Indenture. The Indenture Trustee is hereby initially appointed
Note Registrar for the purpose of registering Notes and transfers and exchanges
of Notes as provided in this Indenture. In the event that, subsequent to the
Closing Date, the Indenture Trustee notifies the Issuer that it is unable to act
as Note Registrar, the Issuer shall appoint another bank or trust company,
having an office or agency located in the Borough of Manhattan, The City of New
York, agreeing to act in accordance with the provisions of this Indenture
applicable to it, and otherwise acceptable to the Indenture Trustee, to act as
successor Note Registrar under this Indenture.

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

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

        (c) At the option of the Holder, Notes may be exchanged for other Notes
of the same Class in any authorized denominations, of a like aggregate principal
amount, upon surrender of the Notes to be exchanged at such office or agency.
Whenever any Notes are so surrendered for exchange, the Issuer shall execute,
and the Indenture Trustee shall authenticate and the Noteholder shall obtain
from the Indenture Trustee, the Notes which the Noteholder making the exchange
is entitled to receive. Every Note presented or surrendered for registration of
transfer or exchange shall be accompanied by a written instrument of transfer in
form satisfactory to the Indenture Trustee and the Note Registrar duly executed
by the Holder thereof or his attorney duly authorized in writing.

        (d) No service charge shall be made for any registration of transfer or
exchange of Notes, but the Indenture Trustee may require payment of a sum
sufficient to cover any tax or governmental charge that may be imposed in
connection with any transfer or exchange of Notes.



                                       10
<PAGE>   18

        (e) All Notes surrendered for registration of transfer or exchange shall
be canceled and subsequently destroyed by the Indenture Trustee.

        SECTION 2.05 Mutilated, Destroyed, Lost or Stolen Notes. If (i) any
mutilated Note is surrendered to the Indenture Trustee, or the Indenture Trustee
receives evidence to its satisfaction of the destruction, loss or theft of any
Note, and (ii) there is delivered to the Indenture Trustee such security or
indemnity as may be required by it to hold the Issuer and the Indenture Trustee
harmless, then, in the absence of notice to the Issuer, the Note Registrar or
the Indenture Trustee that such Note has been acquired by a protected purchaser,
the Issuer shall execute, and upon its request the Indenture Trustee shall
authenticate and deliver, in exchange for or in lieu of any such mutilated,
destroyed, lost or stolen Note, a replacement Note of the same Class. In
connection with the issuance of any new Note under this Section 2.05, the Issuer
may require 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.

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

        Every replacement Note issued pursuant to this Section 2.05 in
replacement of any mutilated, destroyed, lost or stolen Note shall constitute an
original additional contractual obligation of the Issuer, whether or not the
mutilated, destroyed, lost or stolen Note shall be at any time enforceable by
anyone, and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Notes of the same Class duly issued
hereunder.

        The provisions of this Section 2.05 are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Notes.

        SECTION 2.06 Persons Deemed Owners. Prior to due presentment for
registration of transfer of any Note, the Issuer, the Indenture Trustee and any
agent of the Issuer or the 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, and none of the Issuer, the
Indenture Trustee or any agent of the Issuer or the Indenture Trustee shall be
affected by notice to the contrary.

        SECTION 2.07 Payments of Principal and Interest.

        (a) The Class A-1 Notes, the Class A-2 Notes, the Class A-3 Notes and
the Class A-4 Notes shall accrue interest during each Interest Period at the
Class A-1 Rate, the Class A-2 Rate,



                                       11
<PAGE>   19

the Class A-3 Rate, and the Class A-4 Rate, respectively, and such interest
shall be payable on each related Distribution Date as specified in the
applicable Note by applying amounts available pursuant to Section 5.06 of the
Sale and Servicing Agreement and to Section 3.01 of this Indenture. Any
installment of interest or principal payable on any Note that is punctually paid
or duly provided for by the Issuer on the applicable Distribution Date shall be
paid to the Person in whose name such Note (or one or more Predecessor Notes) is
registered on the Record Date by wire transfer in immediately available funds to
the account designated by such nominee, except for the final installment of
principal payable with respect to such Note on a Distribution Date or on the
applicable Final Scheduled Distribution Date, which shall be payable as provided
below.

        (b) The principal of each Note shall be payable in installments on each
Distribution Date by applying amounts available pursuant to Section 5.06 of the
Sale and Servicing Agreement. Notwithstanding the foregoing, the entire unpaid
principal amount of the Notes shall be due and payable, if not previously paid,
from and after the date on which the Indenture Trustee or the Holders of a
majority of the Outstanding Amount of the Notes, voting as a single class
(excluding for such purpose the outstanding principal amount of any Notes held
of record or beneficially owned by NARC II, NMAC or any of their Affiliates,
unless at such time all of the Notes are held of record or beneficially owned by
NARC II, NMAC or any of their Affiliates), have declared the Notes to be
immediately due and payable in the manner provided in Section 5.02 in connection
with an Event of Default. All principal payments on each Class of Notes shall be
made pro rata to the Noteholders of such Class entitled thereto. The Indenture
Trustee shall notify the Person in whose name a Note is registered at the close
of business on the Record Date preceding the Distribution Date on which the
final installment of principal of and interest on such Note will be paid. Such
notice shall be mailed or transmitted by facsimile not less than 15 nor more
than 30 days prior to such final Distribution Date, 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.

        SECTION 2.08 Cancellation. All Notes surrendered for payment,
registration of transfer or exchange shall, if surrendered to any Person other
than the Indenture Trustee, be delivered to the Indenture Trustee and shall be
promptly canceled by the Indenture Trustee. The Issuer may at any time deliver
to the Indenture Trustee for cancellation any Notes previously authenticated and
delivered hereunder which the Issuer may have acquired in any manner whatsoever,
and all Notes so delivered shall be promptly canceled by the Indenture Trustee.
No Notes shall be authenticated in lieu of or in exchange for any Notes canceled
as provided in this Section, except as expressly permitted by this Indenture.
All canceled Notes may be held or disposed of by the Indenture Trustee in
accordance with its standard retention or disposal policy as in effect at the
time unless the Issuer shall direct by an Issuer Order that they be destroyed or
returned to it; provided, that such Issuer Order is timely and the Notes have
not been previously disposed of by the Indenture Trustee.

        SECTION 2.09 Release of Collateral. Subject to Sections 8.05 and 11.01
and the terms of the Basic Documents, the Indenture Trustee shall release
property from the lien of this Indenture only upon receipt of an Issuer Request
accompanied by an Officer's Certificate, an Opinion of Counsel and Independent
Certificates in accordance with TIA Sections 314(c) and



                                       12
<PAGE>   20

314(d)(l) or an Opinion of Counsel in lieu of such Independent Certificates to
the effect that the TIA does not require any such Independent Certificates.

        SECTION 2.10 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 The Depository Trust Company, the initial Clearing Agency, or a
custodian therefor, by, or on behalf of, the Issuer. The Book-Entry Notes shall
be registered initially on the Note Register in the name of Cede & Co., the
nominee of the initial Clearing Agency, and no Note Owner thereof 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 such Note Owners pursuant to
Section 2.12:

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

        (b) the Note Registrar and the Indenture Trustee shall be entitled to
deal with the Clearing Agency for all purposes of this Indenture (including the
payment of principal of and interest on the Notes and the giving of instructions
or directions hereunder) as the authorized representative of 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 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 or of the Notes of any Class,
the Clearing Agency shall be deemed to represent such percentage only to the
extent that it has received instructions to such effect from Note Owners and/or
Clearing Agency Participants owning or representing, respectively, such required
percentage of the beneficial interest in the Notes and has delivered such
instructions to the Indenture Trustee.

        SECTION 2.11 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 such Note Owners pursuant to
Section 2.12, the Indenture Trustee shall give all such notices and
communications specified herein to be given to Holders of the Notes to the
Clearing Agency and shall be deemed to have been given as of the date of
delivery to the Clearing Agency.

        SECTION 2.12 Definitive Notes. If (i) the Seller, the Owner Trustee or
the Administrator advises the Indenture Trustee in writing that the Clearing
Agency is no longer willing or able to properly discharge its responsibilities
with respect to the Book-Entry Notes and



                                       13
<PAGE>   21

the Seller, the Owner Trustee and the Administrator are unable to locate a
qualified successor (and if the Administrator has made such determination, the
Administrator has given written notice thereof to the Indenture Trustee), (ii)
the Seller, the Indenture Trustee or the Administrator at its option advises
each other such party in writing that it elects to terminate the book-entry
system through the Clearing Agency, or (iii) after the occurrence of an Event of
Default or a Servicer Default, Note Owners representing beneficial interests
aggregating a majority of the Outstanding Amount of the Notes of all Classes
advise the Indenture Trustee and the Clearing Agency in writing that the
continuation of a book-entry system through the Clearing Agency or a successor
thereto is no longer in the best interests of the Note Owners acting together as
a single Class, then the Clearing Agency shall notify all Note Owners and the
Indenture Trustee of the occurrence of such event and of the availability of
Definitive Notes to Note Owners requesting the same. Upon surrender to the
Indenture Trustee of the typewritten Notes representing the Book-Entry Notes by
the Clearing Agency, accompanied by registration instructions, the Issuer shall
execute and the Indenture Trustee shall authenticate the Definitive Notes in
accordance with the instructions of the Clearing Agency. None of the Issuer, the
Note Registrar or the Indenture Trustee shall be liable for any delay in
delivery of such instructions and may conclusively rely on, and shall be
protected in relying on, such instructions. Upon the issuance of Definitive
Notes, the Indenture Trustee shall recognize the Holders of the Definitive Notes
as Noteholders. The Indenture Trustee, Issuer and Administrator shall not be
liable for any inability to locate a qualified successor Clearing Agency. From
and after the date of issuance of Definitive Notes, all notices to be given to
Noteholders will be mailed thereto at their addresses of record in the Note
Register as of the relevant Record Date. Such notices will be deemed to have
been given as of the date of mailing.

        SECTION 2.13 Tax Treatment. The Issuer has entered into this Indenture,
and the Notes will be issued, with the intention that, for federal, state and
local income, single business and franchise tax purposes, the Notes will qualify
as indebtedness of the Issuer secured by the Trust Estate or, for periods during
which there is a single beneficial owner of the Certificates, indebtedness of
the Certificateholder issued by the Trust Estate. The Issuer, by entering into
this Indenture, and each Noteholder, by its acceptance of a Note (and each Note
Owner by its acceptance of an interest in the applicable Book-Entry Note), agree
to treat the Notes for federal, state and local income, single business and
franchise tax purposes as indebtedness of the Issuer.

                                   ARTICLE III
                                    Covenants

        SECTION 3.01 Payment of Principal and Interest. In accordance with the
terms of this Indenture, the Issuer will duly and punctually (i) pay the
principal of and interest, if any, on the Notes in accordance with the terms of
the Notes and (ii) cause the Servicer to direct the Indenture Trustee to release
from the Collection Account all other amounts distributable or payable from the
Owner Trust Estate under the Trust Agreement, the Sale and Servicing Agreement
and the Administration Agreement. Without limiting the foregoing and in order to
fulfill such obligations, pursuant to Sections 8.02 and 8.03 hereof, the Issuer
will cause the Servicer to direct the Indenture Trustee to apply all amounts on
deposit in the Collection Account, the Reserve Account and the Yield Supplement
Account on a Distribution Date deposited therein pursuant to the Sale and
Servicing Agreement (i) (a) for the benefit of the Class A-1 Notes, to the Class
A-1 Noteholders, (b) for the benefit of the Class A-2 Notes, to the Class



                                       14
<PAGE>   22

A-2 Noteholders, (c) for the benefit of the Class A-3 Notes, to the Class A-3
Noteholders, and (d) for the benefit of the Class A-4 Notes, to the Class A-4
Noteholders, and (ii) for the benefit of the Certificateholders, to or as
directed by the Owner Trustee or the Administrator, as set forth in Section
5.06, 5.07 and 5.08 of the Sale and Servicing Agreement. Amounts properly
withheld under the Code by any Person from a payment to any Noteholder of
interest and/or principal shall be considered as having been paid by the Issuer
to such Noteholder for all purposes of this Indenture.

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

        SECTION 3.03 Money for Payments To Be Held in Trust. As provided in
Sections 8.02 and 8.03, all payments of amounts due and payable with respect to
any Notes that are to be made from amounts withdrawn from the Collection
Account, the Reserve Account or the Yield Supplement Account pursuant to
Sections 8.02 and 8.03 shall be made on behalf of the Issuer by the Indenture
Trustee or by the Paying Agent, and no amounts so withdrawn from such accounts
for payments of Notes shall be paid over to the Issuer, the Owner Trustee or the
Administrator except as provided in this Section.

        On or before each Distribution Date, the Issuer shall deposit in the
Collection Account or, in accordance with the Sale and Servicing Agreement,
cause to be deposited (including the provision of instructions to the Indenture
Trustee to make any required withdrawals from the Reserve Account or the Yield
Supplement Account and to deposit such amounts in the Collection Account), an
aggregate sum sufficient to pay the amounts then becoming due under the Notes
and the Certificates, such sum to be held in trust for the benefit of the
Persons entitled thereto, and (unless the Paying Agent is the Indenture Trustee)
shall promptly notify the Indenture Trustee of its action or failure so to act.

        The Indenture Trustee, as Paying Agent, hereby agrees with the Issuer
that it will, and the Issuer will cause each Paying Agent other than the
Indenture Trustee, as a condition to its acceptance of its appointment as Paying
Agent, to execute and deliver to the Indenture Trustee an instrument in which
such Paying Agent shall agree with the Indenture Trustee, subject to the
provisions of this Section, that such Paying Agent will:

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



                                       15
<PAGE>   23

        (b) give the Indenture Trustee notice of any default by the Issuer (or
any other obligor upon the Notes) of which it has actual knowledge in the making
of any payment required to be made with respect to the Notes or the release of
any amounts to the Issuer to be paid to the Certificateholders;

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

        (d) immediately resign as a Paying Agent and forthwith pay to the
Indenture Trustee all sums held by it in trust for the payment of Notes (or for
release to the Issuer) 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

        (e) comply with all requirements of the Code with respect to the
withholding from any payments made by it on any Notes or Certificates (or
assisting the Issuer to withhold from payment to the Certificateholders) of any
applicable withholding taxes imposed thereon and with respect to any applicable
reporting requirements in connection therewith.

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

        Subject to applicable laws with respect to escheat of funds, any money
held by the Indenture Trustee or any Paying Agent in trust for the payment of
any amount due with respect to any Note and remaining unclaimed after such
amount has become due and payable and after the Indenture Trustee has taken the
steps described in this paragraph shall be discharged from such trust and be
paid to Children's Hospital Los Angeles upon presentation thereto of an Issuer
Request; and the Holder of such Note shall thereafter, as an unsecured general
creditor, look only to the Issuer for payment thereof, and all liability of the
Indenture Trustee or such Paying Agent with respect to such trust money shall
thereupon cease. In the event that any Noteholder shall not surrender its Notes
for retirement within six months after the date specified in the written notice
of final payment described in Section 2.07, the Indenture Trustee will give a
second written notice to the registered Noteholders that have not surrendered
their Notes for final payment and retirement. If within one year after such
second notice any Notes have not been surrendered, the Indenture Trustee shall,
at the expense and direction of the Issuer, cause to be published once, in a
newspaper published in the English language, customarily published on each
Business Day and of general circulation in The City of New York, notice that
such money remains unclaimed and that, after a date specified therein, which
shall not be less than 30 days from the date of such publication, any unclaimed
balance of such money then remaining will be paid to Children's Hospital Los
Angeles. The Indenture Trustee shall also adopt and employ, at the expense and
direction of the Issuer, any other reasonable means of notification of such
repayment specified by the Issuer or the Administrator.



                                       16
<PAGE>   24

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

        SECTION 3.05 Protection of Trust Estate. The Issuer will from time to
time execute and deliver all such supplements and amendments hereto and all such
financing statements, continuation statements, instruments of further assurance
and other instruments, 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;

        (c) enforce any of the Collateral; or

        (d) preserve and defend title to the Trust Estate and the rights of the
Indenture Trustee and the Noteholders in such Trust Estate against the claims of
all persons and parties.

        The Issuer hereby designates the Indenture Trustee its agent and
attorney-in-fact to execute any financing statement, continuation statement or
other instrument required to be executed pursuant to this Section 3.05.

        SECTION 3.06 Opinions as to Trust Estate.

        (a) On the Closing Date, the Issuer shall furnish to the Indenture
Trustee an Opinion of Counsel either stating that, in the opinion of such
counsel, such action has been taken with respect to the execution, recording and
filing of this Indenture, any indentures supplemental hereto, any requisite
financing statements and continuation statements and any other requisite
documents necessary to perfect and make effective the lien and security interest
of this Indenture or stating that, in the opinion of such counsel, no such
action is necessary to make such lien and security interest effective.

        (b) As and when specified in Section 10.02(h) of the Sale and Servicing
Agreement, the Issuer shall furnish to the Indenture Trustee an Opinion of
Counsel either stating that, in the opinion of such counsel, such action has
been taken with respect to the execution, recording, filing or re-recording and
refiling of this Indenture, any indentures supplemental hereto, any financing
statements and continuation statements and any other requisite documents
necessary to maintain the lien and security interest created by this Indenture
or stating that in the opinion of such counsel no such action is necessary to
maintain such lien and security interest. Such Opinion of Counsel shall also
describe the execution, recording, filing or re-recording and refiling of this
Indenture, any indentures supplemental hereto, any financing statements and



                                       17
<PAGE>   25

continuation statements and any other documents that will, in the opinion of
such counsel, be required to maintain the lien and security interest of this
Indenture until the date in the following calendar year on which such Opinion of
Counsel must again be delivered.

        SECTION 3.07 Performance of Obligations; Servicing of Receivables.

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

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

        (c) The Issuer will punctually perform and observe all of its
obligations and agreements contained in the Basic Documents and in the
instruments and agreements included in the Trust Estate, including but not
limited to filing or causing to be filed all UCC financing statements and
continuation statements required to be filed by the terms of the Trust
Agreement, this Indenture and the Sale and Servicing Agreement in accordance
with and within the time periods provided for herein and therein.

        (d) If an Authorized Officer of the Issuer shall have knowledge of the
occurrence of a Servicer Default under the Sale and Servicing Agreement, the
Issuer shall promptly notify the Indenture Trustee and the Rating Agencies
thereof, and shall specify in such notice the action, if any, the Issuer is
taking with respect of such default. If a Servicer Default shall arise from the
failure of the Servicer to perform any of its duties or obligations under the
Sale and Servicing Agreement with respect to the Receivables, the 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
the Servicer of the Servicer's rights and powers pursuant to Section 8.01 of the
Sale and Servicing Agreement, the Indenture Trustee 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 the Indenture
Trustee. In the event that a Successor Servicer has not been appointed and
accepted its appointment as set forth in Section 8.02 of the Sale and Servicing
Agreement, the Indenture Trustee without further action shall automatically be
appointed the Successor Servicer and shall thereafter be entitled to the Total
Servicing Fee. Notwithstanding the above, the Indenture Trustee shall, if it
shall be legally unable so to act, appoint or petition a court of competent
jurisdiction to appoint, and the predecessor Servicer, if no successor Servicer
has been appointed at the time the predecessor Servicer has ceased to act, may
petition a court of competent jurisdiction to appoint, any established
institution having a net worth of not less than $100,000,000 and whose regular
business shall include the servicing of automobile and/or light-



                                       18

duty truck receivables, as the successor to the Servicer under the Sale and
Servicing Agreement. Upon such appointment, the Indenture Trustee will be
released from the duties and obligations of acting as Successor Servicer, such
release effective upon the effective date of the servicing agreement entered
into between the Successor Servicer and the Issuer.

        In connection with any such appointment, the Indenture Trustee may make
such arrangements for the compensation of such successor as it and such
Successor Servicer shall agree, subject to the limitations set forth below and
in the Sale and Servicing Agreement, and in accordance with Section 8.02 of the
Sale and Servicing Agreement, the Issuer shall enter into an agreement with such
Successor Servicer for the servicing of the Receivables (such agreement to be in
form and substance satisfactory to the Indenture Trustee). If the Indenture
Trustee shall succeed to the 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
hereof shall be inapplicable to the Indenture Trustee in its duties as Successor
Servicer and the servicing of the Receivables. In case the Indenture Trustee
shall become the Successor Servicer, the Indenture Trustee shall be entitled to
appoint as a subservicer any one of its Affiliates, provided that the Indenture
Trustee, in its capacity as Successor Servicer, shall remain fully liable for
the actions and omissions of such Affiliate.

        (f) Upon any termination of the Servicer's rights and powers pursuant to
the Sale and Servicing Agreement, the Issuer shall promptly notify the Indenture
Trustee. As soon as a Successor Servicer is appointed, the Issuer shall notify
the 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 the Indenture Trustee under this Indenture or the rights of the
Indenture Trustee hereunder, the Issuer agrees (i) that it will not, without the
prior written consent of the Indenture Trustee and the Holders of a majority in
Outstanding Amount of the Notes, voting as a single class (excluding for such
purposes the outstanding principal amount of any Notes held of record or
beneficially owned by NMAC, NARC II or any of their Affiliates, unless at such
time all of the Notes are held of record or beneficially owned by NARC II, NMAC
or any of their Affiliates), amend, modify, waive, supplement, terminate or
surrender, or agree to any amendment, modification, waiver, supplement,
termination or surrender of, the terms of any Collateral (except to the extent
otherwise provided in the Sale and Servicing Agreement) or the Basic Documents,
or waive timely performance or observance by the Servicer or the Seller under
the Sale and Servicing Agreement; and (ii) that any such amendment shall not (A)
increase or reduce in any manner the amount of, or accelerate or delay the
timing of, collections of payments on the Receivables or distributions that are
required to be made for the benefit of the Noteholders or change the Interest
Rate or the Specified Reserve Account Balance (except as otherwise provided in
the Basic Documents), in each case without the consent of each of the "adversely
affected" Noteholders, or (B) reduce the aforesaid percentage of the Notes that
is 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 the Indenture Trustee or such Holders, the
Issuer agrees, promptly following a request by the Indenture Trustee to agree to
such amendment and to execute and deliver, in its own name and at its own
expense, such agreements, instruments, consents and other documents as the
Indenture Trustee may deem necessary or appropriate in the circumstances to
implement such amendment and to cause the



                                       19
<PAGE>   27

relevant Basic Documents, as amended, to be enforceable against the Issuer. For
the purposes of clause (ii) above, an amendment will be deemed not to "adversely
affect" a Noteholder of any Class only if each Rating Agency confirms that such
amendment will not result in a reduction or withdrawal of its rating on such
Class of Notes.

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

        (a) except as expressly permitted by Basic Documents, sell, transfer,
exchange or otherwise dispose of any of the properties or assets of the Issuer,
including those included in the Trust Estate, unless directed to do so by the
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) except as may be expressly permitted hereby, (A) 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, (B) permit any lien, charge, excise,
claim, security interest, mortgage or other encumbrance (other than the lien of
this Indenture) to be created on or extend to or otherwise arise upon or burden
the 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 any of the Financed Vehicles and arising
solely as a result of an action or omission of the related Obligor), (C) 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, or (D) dissolve or liquidate in whole or in part; or

        (d) assume or incur any indebtedness other than the Notes or as
expressly contemplated by this Indenture (in connection with the obligation to
reimburse Advances from the Trust Estate, or to pay expenses from the Trust
Estate) or by the Basic Documents as in effect on the date hereof.

        SECTION 3.09 Annual Statement as to Compliance. The Issuer will cause
the Servicer to deliver to the Indenture Trustee concurrently with its delivery
thereof to the Issuer the annual statement of compliance described in Section
4.09 of the Sale and Servicing Agreement. In addition, on the same date annually
upon which such annual statement of compliance is to be delivered by the
Servicer, the Issuer shall deliver to the Indenture Trustee an Officer's
Certificate stating, as to the Authorized Officer signing such Officer's
Certificate, that:

        (a) a review of the activities of the Issuer during such year and of its
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, the Issuer has complied with all conditions and covenants under this
Indenture throughout such year,



                                       20
<PAGE>   28

or, if there has been a default in its compliance with any such condition or
covenant, specifying each such default known to such Authorized Officer and the
nature and status thereof.

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

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

        District of Columbia and shall expressly assume, by an indenture
        supplemental hereto, executed and delivered to the Indenture Trustee, in
        form satisfactory to the Indenture Trustee, the duty to make due and
        punctual payment of the principal of and interest on all Notes and the
        performance or observance of every agreement and covenant of this
        Indenture on the part of the Issuer to be performed or observed, all as

        removal or reduction of the rating then assigned thereby to any Class of

        effect that such transaction will not have any material adverse tax
        consequence to the Issuer, any Noteholder or any Certificateholder;

assets, including those included in the Trust Estate, to any Person, unless:

        or a Person organized and existing under the laws of the United States
        of America or any state or the District of Columbia, (B) expressly
        assume, by an indenture supplemental hereto, executed and delivered to

        be performed or observed, all as provided herein, (C) expressly agrees

and any action the Issuer is taking or proposes to take with respect thereto.

        SECTION 5.02 Acceleration of Maturity; Rescission and Annulment. If an
Event of Default should occur and be continuing, then and in every such case the
Indenture Trustee or the Holders of a majority of the Outstanding Amount of the
Notes, voting as a single class (excluding for such purposes the outstanding

Holders of a majority of the Outstanding Amount of the Notes, voting as a single
class (excluding for such purposes the outstanding principal amount of any Notes
held of record or beneficially owned by NMAC, NARC II or any of their
Affiliates, unless at such time all of the Notes are held of record or
beneficially owned by NARC II, NMAC or any of their Affiliates), by written
notice to the Issuer and the Indenture Trustee, may rescind and annul such
declaration and its consequences if:

        (a) the Issuer has paid or deposited with the Securities Intermediary in
the name of the Indenture Trustee a sum sufficient to pay:

                (i) all payments of principal of and interest on the 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

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

        (b) 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 5.03 Collection of Indebtedness and Suits for Enforcement by
Indenture Trustee.

        (a) The Issuer covenants that if (i) default is made in the payment of
any interest on any Note, so long as any amounts remain unpaid with respect to
the Notes, 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, the Issuer will, upon demand of the Indenture Trustee, pay to the
Indenture Trustee, for the benefit of the Holders of the Notes, the whole amount
then due and payable on the 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 borne
by the Notes and in addition thereto such further amount as shall be sufficient
to cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Indenture Trustee and
its agents and counsel.

        (b) In case the Issuer shall fail forthwith to pay such amounts upon
such demand, the Indenture Trustee, in its own name and as trustee of an express
trust, may institute a Proceeding



                                       27
<PAGE>   35

for the collection of the sums so due and unpaid, and may prosecute such
Proceeding to judgment or final decree, and may enforce the same against the
Issuer or other obligor upon such Notes and collect in the manner provided by
law out of the property of the Issuer or other obligor upon such Notes, wherever
situated, the moneys adjudged or decreed to be payable.

        (c) If an Event of Default occurs and is continuing, the Indenture
Trustee may, as more particularly provided in Section 5.04, in its discretion,
proceed to protect and enforce its rights and the rights of the Noteholders and,
incidentally thereto, the Certificateholders, by such appropriate Proceedings as
the Indenture Trustee shall deem most effective to protect and enforce any such
rights, whether for the specific enforcement of any covenant or agreement in
this Indenture or in aid of the exercise of any power granted herein, or to
enforce any other proper remedy or legal or equitable right vested in the
Indenture Trustee by this Indenture or by law.

        (d) In case there shall be pending, relative to the Issuer or any other
obligor upon the Notes or any Person having or claiming an ownership interest in
the Trust Estate, Proceedings under Title 11 of the United States Code or any
other applicable federal or state bankruptcy, insolvency or other similar law,
or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, sequestrator or similar official shall have been appointed for or
taken possession of the Issuer or its property or such other obligor or Person,
or in case of any other comparable judicial Proceedings relative to the Issuer
or other obligor upon the Notes, or to the creditors or property of the Issuer
or such other obligor, then, irrespective of whether the principal of any Notes
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Indenture Trustee shall have made any
demand pursuant to the provisions of this Section, the 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 the Indenture Trustee (including any claim
        for reasonable compensation to the Indenture Trustee and each
        predecessor Indenture Trustee, and their respective agents, attorneys
        and counsel, and for reimbursement of all expenses and liabilities
        incurred, and all advances made, by the Indenture Trustee and each
        predecessor Indenture Trustee, except as a result of negligence or bad
        faith) and of the Noteholders allowed in such Proceedings;

                (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 the
        Indenture Trustee on their behalf; and

                (iv) to file such proofs of claim and other papers or documents
        as may be necessary or advisable in order to have the claims of the
        Indenture Trustee or the Holders



                                       28
<PAGE>   36

        of Notes allowed in any judicial proceedings relative to the Issuer, its
        creditors and its property.

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

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

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

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

        SECTION 5.04 Remedies; Priorities.

        (a) If an Event of Default shall have occurred and be continuing and
result in the acceleration of the Notes, the Indenture Trustee shall make
payments on the Notes and to the Owner Trustee as set forth in Section 5.06(d)
of the Sale and Servicing Agreement, rather than pursuant to Section 5.06(c)
thereof.

        (b) If the Indenture Trustee, in compliance with Section 5.04(a), is
deemed to have a conflict of interest under the TIA and is required to resign as
Indenture Trustee hereunder, the Issuer shall, pursuant to Section 6.08, cause
the Servicer to appoint a successor Indenture Trustee.

        (c) In accordance with Section 5.04(b), if an Event of Default shall
have occurred and be continuing, the Indenture Trustee may do one or more of the
following (subject to Section 5.05):



                                       29
<PAGE>   37

                (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 the 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 the Indenture Trustee and the Noteholders; and

                (iv) sell the Trust Estate or any portion thereof or rights or
        interest therein, at one or more public or private sales called and
        conducted in any manner permitted by law; provided, however, that the
        Indenture Trustee may not sell or otherwise liquidate the Trust Estate
        following an Event of Default, other than an Event of Default described
        in Section 5.01(a) or (b), unless (A) the Holders of 100% of the
        Outstanding Amount of the Notes, voting as a single class, consent
        thereto (but excluding for purposes of such vote all Notes held or
        beneficially owned by NMAC, NARC II or any of their Affiliates, unless
        at such time all of the Notes are held or beneficially owned by NMAC,
        NARC II and their Affiliates), or (B) the proceeds of such sale or
        liquidation distributable to the Noteholders are sufficient to discharge
        in full all amounts then due and unpaid upon the Notes for principal and
        interest, or (C) the Indenture Trustee determines that the Trust Estate
        may not continue to provide sufficient funds on an ongoing basis to make
        all payments 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
        the Indenture Trustee obtains the consent of Holders of a 66 2/3% of the
        Outstanding Amount of the Notes, voting as a single class (but excluding
        for purposes of such vote all Notes held or beneficially owned by NMAC,
        NARC II or any of their Affiliates, unless at such time all of the Notes
        are held or beneficially owned by NMAC, NARC II and their Affiliates).
        In determining such sufficiency or insufficiency with respect to clause
        (B) and (C), the Indenture Trustee may, but need not, obtain and rely
        upon an opinion of an Independent investment banking or accounting firm
        of national reputation as to the feasibility of such proposed action and
        as to the sufficiency of the Trust Estate for such purpose.

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

        SECTION 5.05 Optional Preservation of the Receivables. If the Notes have
been declared to be due and payable under Section 5.02 following an Event of
Default and such declaration and its consequences have not been rescinded and
annulled, the Indenture Trustee may, unless otherwise directed by the Holders of
at least a majority of the Outstanding Amount of the Notes, voting as a single
class (excluding from such action and calculation any Notes held by NMAC, NARC
II or any of their Affiliates, unless at such time all of the Notes are held of
record or beneficially owned by NARC II, NMAC or any of their Affiliates), but
need not, elect



                                       30
<PAGE>   38

to maintain possession of the Trust Estate and direct the Issuer, Servicer and
Administrator not to take steps to liquidate the Receivables. It is the desire
of the parties hereto and the Noteholders that there be at all times sufficient
funds for the payment of principal of and interest on the Notes, and the
Indenture Trustee shall take such desire into account when determining whether
or not to maintain possession of the Trust Estate. In determining whether to
maintain possession of the Trust Estate, the Indenture Trustee may, but need
not, obtain and rely upon an opinion of an Independent investment banking or
accounting firm of national reputation as to the feasibility of such proposed
action and as to the sufficiency of the Trust Estate for such purpose.

        SECTION 5.06 Limitation of Suits. No Holder of any Note shall have any
right to institute any Proceeding, judicial or otherwise, with respect to this
Indenture or for the appointment of a receiver or trustee, or for any other
remedy hereunder unless such Holder has previously given written notice to the
Indenture Trustee of a continuing Event of Default, and:

        (a) the Event of Default arises from the Servicer's failure to remit
payments when due; or

        (b) the Holders of not less than 25% of the Outstanding Amount of the
Notes, voting as a single class (excluding for such purpose the outstanding
principal amount of any Notes held of record or beneficially owned by NARC II,
NMAC or any of their Affiliates, unless at such time all of the Notes are held
of record or beneficially owned by NARC II, NMAC or any of their Affiliates)
have made written request to the Indenture Trustee to institute such Proceeding
in respect of such Event of Default in its own name as Indenture Trustee
hereunder and have offered to the Indenture Trustee reasonable indemnity against
the costs, expenses and liabilities to be incurred in complying with such
request, the Indenture Trustee for 60 days after its receipt of such notice,
request and offer of indemnity has failed to institute such Proceedings, and no
direction inconsistent with that written request has been given to the Indenture
Trustee during the 60-day period by the holders of a majority in principal
amount of those outstanding Notes (or relevant class or classes of Notes).

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

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

        SECTION 5.07 Unconditional Rights of Noteholders To Receive Principal
and Interest. Notwithstanding any other provisions in this Indenture, the Holder
of any Note shall have the right, which is absolute and unconditional, to
receive payment of the principal of and interest, if any, on such Note on or
after the respective due dates thereof expressed in such Note and in this
Indenture (in each case with reference to the calculations to be made pursuant
to the



                                       31
<PAGE>   39

Sale and Servicing Agreement) and to institute suit for the enforcement of any
such payment, and such right shall not be impaired without the consent of such
Holder.

        SECTION 5.08 Restoration of Rights and Remedies. If the Indenture
Trustee or any Noteholder has instituted any Proceeding to enforce any right or
remedy under this Indenture and such Proceeding has been discontinued or
abandoned for any reason or has been determined adversely to the Indenture
Trustee or to such Noteholder, then and in every such case the Issuer, the
Indenture Trustee and the Noteholders shall, subject to any determination in
such Proceeding, be restored severally and respectively to their former
positions hereunder, and thereafter all rights and remedies of the Indenture
Trustee and the Noteholders shall continue as though no such Proceeding had been
instituted.

        SECTION 5.09 Rights and Remedies Cumulative. No right or remedy herein
conferred upon or reserved to the Indenture Trustee or to the Noteholders is
intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at law
or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

        SECTION 5.10 Delay or Omission Not a Waiver. No delay or omission of the
Indenture Trustee 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 the Indenture Trustee or to the Noteholders may be exercised from time to
time, and as often as may be deemed expedient, by the 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, voting as a single class (excluding for such
purpose the outstanding principal amount of any Notes held of record or
beneficially owned by NARC II, NMAC or any of their Affiliates, unless at such
time all of the Notes are held of record or beneficially owned by NARC II, NMAC
or any of their Affiliates), shall have the right to direct the time, method and
place of conducting any Proceeding for any remedy available to the Indenture
Trustee with respect to the Notes or exercising any trust or power conferred on
the Indenture Trustee; provided that:

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

        (b) any direction to the Indenture Trustee to sell or liquidate the
Trust Estate shall be by Holders of Notes representing not less than the
applicable percentage of the Outstanding Amount of the Notes set forth in
Section 5.04(c)(iv); and

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



                                       32
<PAGE>   40

        Notwithstanding the rights of Noteholders set forth in this Section,
subject to Section 6.01, the Indenture Trustee need not take any action that it
determines 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 5.02 or the
liquidation or sale of the Trust Estate pursuant to Section 5.04, the Holders of
a majority of the Outstanding Amount of the Notes, voting as a single class
(excluding for such purposes the outstanding principal amount of any Notes held
of record or beneficially owned by NMAC, NARC II or any of their Affiliates,
unless at such time all of the Notes are held of record or beneficially owned by
NARC II, NMAC or any of their Affiliates) may waive any past Default or Event of
Default and its consequences except a Default or Event of Default in (a) the
deposit of collections or other required amounts, (b) any required payment from
amounts held in Accounts in respect of amounts due on the Notes, (c) payment of
principal or interest on the Notes, or (d) an Event of Default in respect of a
covenant or provision hereof that cannot be modified or amended without the
consent of the Holder of each Note. In the case of any such waiver, the Issuer,
the Indenture Trustee and the Holders of the Notes shall be restored to their
former positions and rights hereunder, respectively.

        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 or Note Owner by such Holder's acceptance of such
Note or beneficial interest therein, as the case may be, shall be deemed to have
agreed, that any court may in its discretion require, in any suit for the
enforcement of any right or remedy under this Indenture, or in any suit against
the Indenture Trustee for any action taken, suffered or omitted by it as
Indenture Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to (a) any suit instituted by the
Indenture Trustee, (b) any suit instituted by any Noteholder, or a group of
Noteholders, in each case holding in the aggregate more than 10% of the
Outstanding Amount of the Notes, (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.

        SECTION 5.14 Waiver of Stay or Extension Laws. The Issuer covenants (to
the extent that it may lawfully do so) that it will not at any time insist upon,
or plead or in any manner whatsoever, claim or take the benefit or advantage of,
any stay or extension law wherever enacted, now or at any time hereafter in
force, that may affect the covenants or the performance of this Indenture; and
the Issuer (to the extent that it may lawfully do so) hereby expressly waives
all benefit or advantage of any such law, and covenants that it will not hinder,



                                       33
<PAGE>   41

delay or impede the execution of any power herein granted to the Indenture
Trustee, but will suffer and permit the execution of every such power as though
no such law had been enacted.

        SECTION 5.15 Action on Notes. The Indenture Trustee's right to seek and
recover judgment on the Notes or under this Indenture shall not be affected by
the seeking, obtaining or application of any other relief under or with respect
to this Indenture. Neither the lien of this Indenture nor any rights or remedies
of the Indenture Trustee or the Noteholders shall be impaired by the recovery of
any judgment by the Indenture Trustee against the Issuer or by the levy of any
execution under such judgment upon any portion of the Trust Estate or upon any
of the assets of the Issuer. Any money or property collected by the Indenture
Trustee shall be applied in accordance with Section 5.04(a).

        SECTION 5.16 Performance and Enforcement of Certain Obligations.

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

        (b) If an Event of Default has occurred and is continuing, the 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 a
majority of the Outstanding Amount of the Notes, voting as a single class
(excluding for such purposes the outstanding principal amount of any Notes held
of record or beneficially owned by NMAC, NARC II or any of their Affiliates,
unless at such time all of the Notes are held of record or beneficially owned by
NARC II, NMAC or any of their Affiliates), shall, exercise all rights, remedies,
powers, privileges and claims of the Issuer against the Seller or the Servicer
under or in connection with the Sale and Servicing Agreement or the Purchase
Agreement, or against the Administrator under the Administration Agreement,
including the right or power to take any action to compel or secure performance
or observance by the Seller, the Servicer or the Administrator, of each of their
obligations to the Issuer thereunder and to give any consent, request, notice,
direction, approval, extension, or waiver thereunder and any right of the Issuer
to take such action shall be suspended.

                                   ARTICLE VI
                              The Indenture Trustee

        SECTION 6.01 Duties of Indenture Trustee. The Indenture Trustee, both
prior to and after the occurrence of a Servicer Default under the Sale and
Servicing Agreement,



                                       34
<PAGE>   42

undertakes to perform such duties and only such duties as are specifically set
forth in this Indenture.

        (a) The Indenture Trustee, upon receipt of all resolutions,
certificates, statements, opinions, reports, documents, orders or other
instruments furnished to the Indenture Trustee that shall be specifically
required to be furnished pursuant to any provision of this Indenture, shall
examine them to determine whether they conform on their face to the requirements
of this Indenture.

        (b) No provision of this Indenture shall be construed to relieve the
Indenture Trustee from liability for its own negligent action, its own negligent
failure to act, its own bad faith or its own willful misfeasance; provided,
however, that:

                (i) the duties and obligations of the Indenture Trustee shall be
        determined solely by the express provisions of this Indenture, the
        Indenture Trustee shall not be liable except for the performance of such
        duties and obligations as are specifically set forth in this Indenture,
        no implied covenants or obligations shall be read into this Indenture
        against the Indenture Trustee, the permissive right of the Indenture
        Trustee to do things enumerated in this Indenture shall not be construed
        as a duty and, in the absence of bad faith on the part of the Indenture
        Trustee, the Indenture Trustee may conclusively rely, as to the truth of
        the statements and the correctness of the opinions expressed therein,
        upon any certificates or opinions furnished to the Indenture Trustee and
        conforming on their face to the requirements of this Indenture;

                (ii) the Indenture Trustee shall not be personally liable for an
        error of judgment made in good faith by a Responsible Officer, unless it
        shall be proved that the Indenture Trustee was negligent in performing
        its duties in accordance with the terms of this Indenture; and

                (iii) the Indenture Trustee shall not be personally liable with
        respect to any action taken, suffered or omitted to be taken in good
        faith in accordance with the direction of (i) the Holders of at least a
        majority of the Outstanding Amount of the Notes, voting as a single
        class (excluding for such purposes the outstanding principal amount of
        any Notes held of record or beneficially owned by NARC II, NMAC or any
        of their Affiliates, unless at such time all of the Notes are held of
        record or beneficially owned by NARC II, NMAC or any of their
        Affiliates), relating to the time, method and place of conducting any
        proceeding for any remedy available to the Indenture Trustee, or
        exercising any trust or power conferred upon the Indenture Trustee under
        this Indenture.

        (c) The Indenture Trustee shall not be required to expend or risk its
own funds or otherwise incur financial liability in the performance of any of
its duties under this Indenture, or in the exercise of any of its rights or
powers, if there shall be reasonable grounds for believing that the repayment of
such funds or adequate indemnity against such risk or liability is not
reasonably assured to it.

        (d) All information obtained by the Indenture Trustee regarding the
Obligors and the Receivables contained in the Trust, whether upon the exercise
of its rights under this Indenture or



                                       35
<PAGE>   43

otherwise, shall be maintained by the Indenture Trustee in confidence and shall
not be disclosed to any other Person, unless such disclosure is required by any
applicable law or regulation or pursuant to subpoena.

        (e) If (i) pursuant to Section 3.02 of the Sale and Servicing Agreement,
a Responsible Officer of the Indenture Trustee discovers that a representation
or warranty with respect to a Receivable was incorrect as of the time specified
with respect to such representation and warranty and such incorrectness
materially and adversely affects such Receivable, or (ii) pursuant to Section
4.06 of the Sale and Servicing Agreement, a Responsible Officer of the Indenture
Trustee discovers that a covenant of the Servicer has been breached with respect
to a Receivable that would materially and adversely affect such Receivable, the
Indenture Trustee shall give prompt written notice to the Servicer and the Owner
Trustee of such incorrectness.

        SECTION 6.02 Rights of Indenture Trustee.

        (a) Except as otherwise provided in Section 6.01:

                (i) the Indenture Trustee may rely and shall be protected in
        acting or refraining from acting upon any resolution, Officer's
        Certificate, certificate of an authorized signatory, certificate of
        auditors or any other certificate, statement, instrument, opinion,
        report, notice, request, consent, order, appraisal, bond or other paper
        or document believed by it to be genuine and to have been signed or
        presented by the proper party or parties;

                (ii) the Indenture Trustee may consult with counsel and any
        Opinion of Counsel shall be full and complete authorization and
        protection in respect of any action taken or suffered or omitted by it
        under this Indenture in good faith and in accordance with such Opinion
        of Counsel;

                (iii) the Indenture Trustee shall be under no obligation to
        exercise any of the rights or powers vested in it by this Indenture or
        the Sale and Servicing Agreement, or to institute, conduct or defend any
        litigation under this Indenture, or in relation to this Indenture or the
        Sale and Servicing Agreement, at the request, order or direction of any
        of the Noteholders pursuant to the provisions of this Indenture or the
        Sale and Servicing Agreement, unless such Noteholders shall have offered
        to the Indenture Trustee reasonable security or indemnity against the
        costs, expenses and liabilities that may be incurred therein or thereby;

                (iv) the Indenture Trustee shall not be personally liable for
        any action taken, suffered or omitted by it in good faith and reasonably
        believed by it to be authorized or within the discretion or rights or
        powers conferred upon it by this Indenture;

                (v) the Indenture Trustee shall not be bound to recalculate,
        reverify, or make any investigation into the facts of matters stated in
        any resolution, certificate, statement, instrument, opinion, report,
        notice, request, consent, order, approval, bond or other paper or
        document, unless requested in writing to do so by Holders of Notes
        evidencing not less than 25% of the aggregate Outstanding Amount of the
        Notes; provided, however, that if the payment within a reasonable time
        to the Indenture Trustee of the costs, expenses or



                                       36
<PAGE>   44

        liabilities likely to be incurred by it in the making of such
        investigation is, in the opinion of the Indenture Trustee, not
        reasonably assured to the Indenture Trustee by the security afforded to
        it by the terms of this Indenture, the Indenture Trustee may require
        reasonable indemnity against such cost, expense or liability as a
        condition to so proceeding; the reasonable expense of every such
        examination shall be paid by the Administrator or, if paid by the
        Indenture Trustee, shall be reimbursed by the Administrator upon demand;
        and nothing in this clause shall derogate from the obligation of the
        Servicer to observe any applicable law prohibiting disclosure of
        information regarding the Obligors; and

                (vi) the Indenture Trustee may execute any of the trusts or
        powers under this Indenture or perform any duties under this Indenture
        either directly or by or through agents or attorneys or a custodian.

        (b) No Noteholder will have any right to institute any proceeding with
respect to this Indenture except upon satisfying the conditions set forth in
Section 5.06.

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

        SECTION 6.04 Indenture Trustee's Disclaimer. The Indenture Trustee makes
no representations as to the validity or sufficiency of this Indenture or of the
Notes (other than the execution by the Indenture Trustee on behalf of the Trust
of, and the certificate of authentication on, the Notes), or of the
Certificates. The Indenture Trustee shall have no obligation to perform any of
the duties of the Servicer or the Administrator unless explicitly set forth in
this Indenture. The Indenture Trustee shall at no time have any responsibility
or liability for or with respect to the legality, validity and enforceability of
the Notes or any Receivable, any ownership interest in any Financed Vehicle, or
the maintenance of any such ownership interest, or for or with respect to the
efficacy of the Trust or its ability to generate the payments to be distributed
to Noteholders under this Indenture, including without limitation the validity
of the assignment of the Receivables to the Trust or of any intervening
assignment; the existence, condition, location and ownership of any Receivable
or Financed Vehicle; the existence and enforceability of any physical damage or
credit life or credit disability insurance; the existence and contents of any
retail installment sales contract or any computer or other record thereof; the
completeness of any retail installment sales contract; the performance or
enforcement of any retail installment sales contract; the compliance by the
Issuer with any covenant or the breach by the Issuer, Seller or Servicer of any
warranty or representation made under this Indenture or in any Basic Document or
other related document and the accuracy of any such warranty or representation
prior to the Indenture Trustee's receipt of notice or other discovery of any
noncompliance therewith or any breach thereof; the acts or omissions of the
Issuer, Seller or the Servicer; or any action by the Indenture Trustee taken at
the instruction of the Servicer, provided, however, that the foregoing shall not
relieve the Indenture Trustee of its obligation to perform its duties under this
Indenture. Except with respect to a claim based on the failure of the Indenture
Trustee to perform its duties under this Indenture or based on the Indenture
Trustee's willful misconduct, bad faith or



                                       37
<PAGE>   45

negligence, no recourse shall be had for any claim based on any provision of
this Indenture, the Notes or Certificates or assignment thereof against the
institution serving as the Indenture Trustee in its individual capacity. The
Indenture Trustee shall not have any personal obligation, liability or duty
whatsoever to any Noteholder or any other Person with respect to any such claim,
and any such claim shall be asserted solely against the Trust or any indemnitor
who shall furnish indemnity as provided in this Indenture. The Indenture Trustee
shall not be accountable for the use or application by the Issuer of any of the
Notes or of the proceeds of such Notes, or for the use or application of any
funds paid to the Servicer in respect of the Notes.

        SECTION 6.05 Notice of Defaults. If a Responsible Officer of the
Indenture Trustee knows that a Default has occurred and is continuing, the
Indenture Trustee shall mail to each Noteholder notice of such Default within 10
days of the occurrence thereof. Except in the case of a Default in payment of
principal of or interest on any Note, the Indenture Trustee may withhold such
notice if and so long as a committee of its Responsible Officers in good faith
determines that withholding the notice is in the interests of Noteholders.

        SECTION 6.06 Reports by Indenture Trustee to Holders. The Indenture
Trustee shall deliver or cause to be delivered annually to each Noteholder of
record such information as may be required to enable such holder to prepare its
federal and state income tax returns. The Indenture Trustee shall also deliver
or cause to be delivered annually to each Noteholder of record a report relating
to its eligibility and qualification to continue as Indenture Trustee under this
Indenture, any amounts advanced by it under this Indenture, the amount, interest
rate and maturity date of certain indebtedness owed by the Trust to such
Indenture Trustee, in its individual capacity, the property and funds physically
held by such Indenture Trustee in its capacity as such, and any action taken by
it that materially affects the Notes and that has not been previously reported.

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



                                       38
<PAGE>   46

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

        SECTION 6.08 Replacement of Indenture Trustee. The Indenture Trustee may
resign at any time by providing written notice of its resignation to the Issuer.
The Administrator may remove the Indenture Trustee if:

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

        (b) the Indenture Trustee is adjudged a bankrupt or insolvent;

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

        (d) the Indenture Trustee otherwise becomes legally or practically
incapable of fulfilling its duties hereunder.

        If the Indenture Trustee resigns or is removed or if a vacancy exists in
the office of Indenture Trustee for any reason (the Indenture Trustee in such
event being referred to herein as the retiring Indenture Trustee), the Servicer
shall promptly appoint a successor Indenture Trustee. No resignation or removal
of the Indenture Trustee and no appointment of a successor Indenture Trustee
shall become effective until the acceptance of appointment by the successor
Indenture Trustee pursuant to this Section 6.08.

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

        If a successor Indenture Trustee does not take office within 30 days
after the retiring Indenture Trustee resigns or is removed, the retiring
Indenture Trustee, the Administrator 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.

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

        Notwithstanding the replacement of the Indenture Trustee pursuant to
this Section, the Issuer's and the Administrator's obligations under Section
6.07 shall continue for the benefit of the retiring Indenture Trustee.



                                       39
<PAGE>   47

        SECTION 6.09 Successor Indenture Trustee by Merger. If the Indenture
Trustee consolidates with, merges or converts into, or transfers all or
substantially all its corporate trust business or assets to, another Person, the
resulting, surviving or transferee corporation without any further act shall be
the successor Indenture Trustee if such surviving Person or transferee
corporation or banking shall be otherwise qualified and eligible under Section
6.11. The Indenture Trustee shall provide the Issuer, the Servicer and the
Rating Agencies reasonable prior written notice of any such transaction.

        In case at the time such successor or successors by merger, conversion
or consolidation to the Indenture Trustee shall succeed to the trusts created by
this Indenture any of the Notes shall have been authenticated but not delivered,
any such successor to the Indenture Trustee may adopt the certificate of
authentication of any predecessor trustee, and deliver such Notes so
authenticated; and in case at that time any of the Notes shall not have been
authenticated, any successor to the Indenture Trustee may authenticate such
Notes either in the name of any predecessor hereunder or in the name of the
successor to the Indenture Trustee; and in all such cases such certificates
shall have the full force which it is anywhere in the Notes or in this Indenture
provided that the certificate of the 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,
for the purpose of meeting any legal requirement of any jurisdiction in which
any part of the Trust Estate may at the time be located, the Indenture Trustee
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 Estate, or any part hereof, and, subject to the other provisions of
this Section, such powers, duties, obligations, rights and trusts as the
Indenture Trustee may consider necessary or desirable. No co-trustee or separate
trustee hereunder shall be required to meet the terms of eligibility as a
trustee under Section 6.11 and no notice to Noteholders of the appointment of
any co-trustee or separate trustee shall be required under Section 6.08 hereof.

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



                                       40
<PAGE>   48

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

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

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

        (d) Any separate trustee or co-trustee may at any time constitute the
Indenture Trustee, its agent or attorney-in-fact with full power and authority,
to the extent not prohibited by law, to do any lawful act under or in respect of
this 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 vest in and be
exercised by the Indenture Trustee, to the extent permitted by law, without the
appointment of a new or successor trustee.

        SECTION 6.11 Eligibility; Disqualification. The Indenture Trustee shall
at all times satisfy the requirements of TIA Section 310(a). The Indenture
Trustee shall have a combined capital and surplus of at least $50,000,000 as set
forth in its most recent published annual report of condition and it or its
parent shall have a long-term debt rating of "Baa3" or better by Moody's or
shall otherwise be acceptable to Moody's. The Indenture Trustee shall comply
with TIA Section 310(b), including the optional provision permitted by the
second sentence of TIA Section 310(b)(9); provided, however, that there shall be
excluded from the operation of TIA Section 310(b)(1) any indenture or indentures
under which other securities of the Issuer are outstanding if the requirements
for such exclusion set forth in TIA Section 310(b)(1) are met.

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

        SECTION 6.13 Acknowledgement by Indenture Trustee of its Obligations
Under the Sale and Servicing Agreement. The Indenture Trustee hereby agrees and
consents to the provisions of the Sale and Servicing Agreement applicable to it
(including, without limitation, Sections 5.06, 5.07, 5.09 thereof) and agrees to
be bound by such provisions.

                                   ARTICLE VII
                         Noteholders' Lists and Reports

        SECTION 7.01 Note Registrar To Furnish Names and Addresses of
Noteholders. The Note Registrar shall furnish or cause to be furnished to the
Indenture Trustee, the Owner Trustee, the Servicer or the Administrator, within
15 days after receipt by the Note Registrar of a written request therefrom, a
list of the names and addresses of the Noteholders of any Class as of the most
recent Record Date. If three or more Noteholders, or one or more Holders
evidencing not less than 25% of the Outstanding Amount of the Notes (hereinafter
referred to as "Applicants"), apply in writing to the Indenture Trustee, and
such application states that the Applicants desire to communicate with other
Noteholders with respect to their rights under this Indenture or under the Notes
and such application is accompanied by a copy of the communication that such
Applicants propose to transmit, then the Indenture Trustee shall, within five
Business Days after the receipt of such application, afford such Applicants
access, during normal business hours, to the current list of Noteholders. Such
Indenture Trustee may elect not to afford the requesting Noteholders access to
the list of Noteholders if it agrees to mail the desired communication by proxy,
on behalf of and at the expense of the requesting Noteholders, to all
Noteholders. Every Noteholder, by receiving and holding a Note, agrees with the
Indenture Trustee and the Issuer that none of the Indenture Trustee, the Owner
Trustee, the Issuer, the Servicer or the Administrator shall be held accountable
by reason of the disclosure of any such information as to the names and
addresses of the Noteholders under this Indenture, regardless of the source from
which such information was derived.

        If the Indenture Trustee shall cease to be the Note Registrar, then
thereafter the Administrator will furnish or cause to be furnished to the
Indenture Trustee not more than five days after the most recent Record Date or
at such other times as the Indenture Trustee reasonably may request in writing,
a list, in such form as the Indenture Trustee reasonably may require, of the
names and addresses of the Holders of Notes as of such Record Date.

        SECTION 7.02 Preservation of Information; Communications to Noteholders.

        (a) The Indenture Trustee shall preserve, in as current a form as is
reasonably practicable, the names and addresses of the Holders of Notes
contained in the most recent list furnished to the Indenture Trustee as provided
in Section 7.01 and the names and addresses of Holders of Notes received by the
Indenture Trustee in its capacity as Note Registrar. The Indenture Trustee may
destroy any list furnished to it as provided in such Section 7.01 upon receipt
of a new list so furnished.

        (b) Noteholders may communicate pursuant to TIA Section 312(b) with
other Noteholders with respect to their rights under this Indenture or under the
Notes.

        (c) The Issuer, the Indenture Trustee and the Note Registrar shall have
the protection of TIA Section 3.12(c).

<PAGE>   50

        SECTION 7.03 Reports by Issuer.

        (a) The Issuer shall:

                (i) file with the Indenture Trustee, within 15 days after the
        Issuer is required to file the same with the Commission, copies of the
        annual reports and of the information, documents and other reports (or
        copies of such portions of any of the foregoing as the Commission may
        from time to time by rules and regulations prescribe) that the Issuer
        may be required to file with the Commission pursuant to Section 13 or
        15(d) of the Exchange Act;

                (ii) file with the Indenture Trustee and the Commission in
        accordance with the rules and regulations prescribed from time to time
        by the Commission such additional information, documents and reports
        with respect to compliance by the Issuer with the conditions and
        covenants of this Indenture as may be required from time to time by such
        rules and regulations; and

                (iii) supply to the Indenture Trustee (and the Indenture Trustee
        shall transmit by mail to all Noteholders described in TIA Section
        313(c)) such summaries of any information, documents and reports
        required to be filed by the Issuer pursuant to clauses (i) and (ii) of
        this Section 7.03(a) and by rules and regulations prescribed from time
        to time by the Commission.

        (b) Unless the Issuer otherwise determines, the fiscal year of the
Issuer shall end on March 31 of each year, unless the fiscal year of the
Servicer ends on some other date, in which case, the fiscal year of the Issuer
shall be the same as the fiscal year of the Servicer.

        SECTION 7.04 Reports by Indenture Trustee. If required by TIA Section
313(a), within 60 days after each anniversary of the Closing Date beginning with
April 26, 2002, the Indenture Trustee shall mail to each Noteholder as required
by TIA Section 313(c) a brief report dated as of such date that complies with
TIA Section 313(a). The Indenture Trustee also shall comply with TIA Section
313(b).

        A copy of each report at the time of its mailing to Noteholders shall be
filed by the Indenture Trustee with the Commission and each stock exchange, if
any, on which the Notes are listed. The Issuer shall notify the Indenture
Trustee if and when the Notes are listed on any stock exchange.

                                  ARTICLE VIII
                      Accounts, Disbursements and Releases

        SECTION 8.01 Collection of Money. Except as otherwise expressly provided
herein, the Indenture Trustee may demand payment or delivery of, and shall

        SECTION 8.03 General Provisions Regarding Accounts.

        (a) So long as no Default or Event of Default shall have occurred and be
continuing, all or a portion of the funds in the Collection Account shall be
invested in Eligible Investments and reinvested by the Indenture Trustee at the
written direction of the Servicer, subject to the



                                       44
<PAGE>   52

provisions of Section 5.01 of the Sale and Servicing Agreement. All income or
other gain from investments of moneys deposited in the Collection Account shall
be deposited by the Indenture Trustee in the Collection Account and paid to the
Servicer as servicing compensation on any Business Day on or after which such
amount is deposited in the Collection Account, and any loss resulting from such
investments shall be charged to such account. The Servicer will not direct the
Indenture Trustee, and the Issuer shall cause the Servicer not, to make any
investment of any funds or to sell any investment held in the Collection Account
unless the security interest Granted and perfected in such account will continue
to be perfected in such investment or the proceeds of such sale, in either case
without any further action by any Person, and, in connection with any direction
to the Indenture Trustee to make any such investment or sale, if requested by
the Indenture Trustee, the Servicer shall deliver to the Indenture Trustee an
Opinion of Counsel, acceptable to the Indenture Trustee, to such effect.

        (b) So long as no Default or Event of Default shall have occurred and be
continuing, all or a portion of the funds in the Reserve Account and the Yield
Supplement Account shall be invested in Eligible Investments and reinvested by
the Indenture Trustee at the written direction of the Servicer, subject to the
provisions of Section 5.07 and Section 5.08, respectively, of the Sale and
Servicing Agreement and the provisions of the Securities Account Control
Agreement. All income or other gain from investments of moneys deposited in the

Business Day on or after which such amount is deposited in the Reserve Account.
All income or other gain from investments of moneys deposited in the Yield
Supplement Account shall be deposited into the Collection Account on each
Distribution Date. Subject to the right of the Indenture Trustee to make
withdrawals therefrom, as directed by the Servicer, for the purposes and in the
amounts set forth in Section 5.06 of the Sale and Servicing Agreement, the
Reserve Account and all funds held therein shall be the property of the Seller
and not the property of the Trust, the Owner Trustee or the Indenture Trustee.
The Seller will grant to the Indenture Trustee, for the benefit of the
Noteholders, a security interest in all funds (including Eligible Investments)
in the Reserve Account (including the Reserve Account Initial Deposit) and the
proceeds thereof, and the Issuer will grant to the Indenture Trustee, for the
benefit of the Noteholders, a security interest in all funds (including Eligible
Investments) in the Yield Supplement Account and the proceeds thereof, and the
Indenture Trustee shall have all of the rights of a secured party under the UCC
with respect thereto; provided that all income from the investment of funds in
the Reserve Account, and the right to receive such income are retained by the
Seller and are not transferred, assigned or otherwise conveyed hereunder; and
provided, further, that amounts on deposit in the Yield Supplement Account in
excess of the Required Yield Supplement Amount will be deposited into the
Collection Account for distribution in accordance with the terms of Section
5.06(c) of the Sale and Servicing Agreement. The Servicer will not direct the
Indenture Trustee to make any investment of any funds or to sell any investment
held in the Reserve Account or the Yield Supplement Account unless the security
interest granted and perfected in such account will continue to be perfected in
such investment or the proceeds of such sale, in either case without any further
action by any Person, and, in connection with any direction to the Indenture
Trustee to make any such investment or sale, if requested by the Indenture
Trustee, the Servicer shall deliver to the Indenture Trustee an Opinion of
Counsel, acceptable to the Indenture Trustee, to such effect.

        (c) Subject to Section 6.01(c), the Indenture Trustee shall not in any
way be held liable by reason of any insufficiency in the Collection Account, the
Reserve Account or the Yield Supplement Account resulting from any loss on any
Eligible Investment included therein at the direction of the Servicer, except
for losses attributable to the Indenture Trustee's failure to make payments on
such Eligible Investments issued by the Indenture Trustee, in its commercial
capacity as principal obligor and not as trustee, in accordance with the terms
thereof.

        (d) If (i) the Servicer shall have failed to give investment directions
for any funds on deposit in the Collection Account, the Reserve Account or the
Yield Supplement Account, to the Indenture Trustee by 5:00 p.m. Eastern Time (or
such other time as may be agreed by the Servicer and Indenture Trustee) on any
Business Day or (ii) a Default or Event of Default shall have occurred and be
continuing with respect to the Notes but the Notes shall not have been declared
due and payable pursuant to Section 5.02 or (iii) if such Notes shall have been
declared due and payable following an Event of Default, amounts collected or
receivable from the Trust Estate are being applied in accordance with Section
5.05 as if there had not been such a declaration, then the Indenture Trustee
shall, to the fullest extent practicable, invest and reinvest funds in the
Accounts in one or more Eligible Investments specified in clauses (i), (iv) or
(vi) of the definition of Eligible Investments provided in the Sale and
Servicing Agreement. If the Indenture Trustee invests and reinvests funds in the
Reserve Account or the Yield Supplement Account pursuant to clause (ii) or
clause (iii) above, the Indenture Trustee shall issue a prohibition notice to
the securities intermediary as provided in the Securities Account Control
Agreement. If the Default or Event of Default that caused the Indenture Trustee
to assume control over the investment of funds in the Reserve Account and Yield
Supplement Account has been waived and the acceleration, if any, of the Notes
has been rescinded, the Indenture Trustee shall issue a rescission of
prohibition notice to the securities intermediary as provided in the Securities
Account Control Agreement.

        SECTION 8.04 Release of Trust Estate.

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

        (b) The Indenture Trustee shall, at such time as there are no Notes
outstanding and all sums due the Indenture Trustee pursuant to Section 6.07 have
been paid, release any remaining portion of the Trust Estate that secured the
Notes from the lien of this Indenture and release to or to the order of the
Issuer, or, in the case of the Reserve Account or the Yield Supplement Account,
to the Seller, any funds entitled thereto then on deposit in the Collection
Account, the Reserve Account and the Yield Supplement Account, as the case may
be. The Indenture Trustee shall release property from the lien of this Indenture
pursuant to this Section 8.04(b) only upon receipt of an Issuer Request
accompanied by an Officer's Certificate and (if required by the TIA)



                                       46
<PAGE>   54

Independent Certificates in accordance with TIA Sections 314(c) and 314(d)(1)
meeting the applicable requirements of Section 11.01.

        SECTION 8.05 Release of Receivables Upon Purchase by the Seller or the
Servicer. (a) Upon repurchase of any Receivable by the Seller pursuant to
Section 3.02 of the Sale and Servicing Agreement or any purchase of any
Receivable by the Servicer pursuant to Section 4.06 or Section 9.01 of the Sale
and Servicing Agreement, the Indenture Trustee, on behalf of the Noteholders,
shall, without further action, be deemed to release from the Lien of this
Indenture such repurchased Receivable, all monies due or to become due with
respect thereto and all proceeds thereof and the other property with respect to
such Receivable, and all security and any documents relating thereto, and the
Seller or the Servicer, as applicable, shall thereupon own each such Receivable,
and all such related security and documents, free of any further obligation to
the Issuer, the Indenture Trustee or the Noteholders with respect thereto.

        (b) The Indenture Trustee shall execute such documents and instruments
and take such other actions as shall be reasonably requested by the Seller or
the Servicer, as the case may be, to effect the release of such Receivable
pursuant hereto and the assignment of such Receivable by the Issuer pursuant to
Section 9.02 of the Sale and Servicing Agreement.

        SECTION 8.06 Opinion of Counsel. The Indenture Trustee shall receive at
least seven days notice when requested by the Issuer to take any action pursuant
to Section 8.04(a), accompanied by copies of any instruments involved, and the
Indenture Trustee shall also require, except in connection with any action
contemplated by Section 8.04(b), as a condition to such action, an Opinion of
Counsel, in form and substance satisfactory to the Indenture Trustee, stating
the legal effect of any such action, outlining the steps required to complete
the same, and concluding that all conditions precedent to the taking of such
action have been complied with and such action will not materially and adversely
impair the security for the Notes or the rights of the Noteholders in
contravention of the provisions of this Indenture; provided, however, that such
Opinion of Counsel shall not be required to express an opinion as to the fair
value of the Trust Estate. Counsel rendering any such opinion may rely, without
independent investigation, on the accuracy and validity of any certificate or
other instrument delivered to the Indenture Trustee in connection with any such
action.

                                   ARTICLE IX

        contained herein and in the Notes;

                (iii) to add to the covenants of the Issuer, for the benefit of

        conferred upon the Issuer;

                (iv) to convey, transfer, assign, mortgage or pledge any

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

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

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

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

        (b) The Issuer and the Indenture Trustee, when authorized by an Issuer
Order, may, also without the consent of any of the Holders of the Notes, enter
into an indenture or indentures supplemental hereto for the purpose of adding
any provisions to, or changing in any manner or eliminating any of the
provisions of, this Indenture or of modifying in any manner the rights of the
Holders of the Notes under this Indenture; provided, however, that such action
shall not materially and adversely affect the interests of any Noteholder.

        SECTION 9.02 Supplemental Indentures with Consent of Noteholders. The
Issuer and the Indenture Trustee, when authorized by an Issuer Order, also may,
with prior notice to the Rating Agencies and with the consent of the Holders of
a majority of the Outstanding Amount of the Notes, voting as a single class
(excluding for such purpose the outstanding principal amount of any Notes held
of record or beneficially owned by NARC II, NMAC or any of their Affiliates,
unless at such time all of the Notes are held of record or beneficially owned by
NARC II, NMAC or any of their Affiliates), by Action of such Holders delivered
to the Issuer and the Indenture Trustee, enter into an indenture or indentures
supplemental hereto for the purpose of adding any



                                       48
<PAGE>   56

provisions to, or changing in any manner or eliminating any of the provisions

        (b) impair the right to institute suit for the enforcement of the

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;

        (c) reduce the percentage of the Outstanding Amount of the Notes, the

Indenture that specify the applicable percentage of Outstanding Amount of the

the lien of this Indenture with respect to any part of the Trust Estate or,
except as otherwise permitted or contemplated herein, terminate the lien of this
Indenture on any property at any time subject hereto or deprive the Holder of
any Note of the security provided by the lien of this Indenture.

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

        It shall not be necessary for any Action of Noteholders under this
Section to approve the particular form of any proposed supplemental indenture,

        Promptly after the execution by the Issuer and the Indenture Trustee of
any supplemental indenture pursuant to this Section, the Indenture Trustee shall
mail to the Holders of the Notes to



                                       49

Trustee shall so determine, new Notes so modified as to conform, in the opinion
of the Indenture Trustee and the Issuer, to any such supplemental indenture may
be prepared and executed by the Issuer and authenticated and delivered by the
Indenture Trustee in exchange for Outstanding Notes.

the Rating Agencies as soon as practicable after their receipt of notice from
the Servicer.

        than one percent of the Outstanding Amount of the Notes.

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

                (iii) Notwithstanding Section 2.09 or any other provision of
        this Section, the Issuer may, without compliance with the requirements
        of the other provisions of this Section, (A) collect, liquidate, sell or
        otherwise dispose of Receivables and Financed Vehicles as and to the
        extent permitted or required by the Basic Documents and (B) make cash
        payments out of the Accounts as and to the extent permitted or required
        by the Basic Documents so long as the Issuer shall deliver to the
        Indenture Trustee every six months, commencing October 15, 2001, an
        Officer's Certificate of the Issuer stating that all such dispositions
        of Collateral that occurred during the preceding six calendar months
        were in the ordinary course of the Issuer's business and that the
        proceeds thereof were applied in accordance with the Basic Documents.

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



                                       52

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

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

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

        SECTION 11.03 Acts of Noteholders.

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

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

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

        (d) Any request, demand, authorization, direction, notice, consent,
waiver or other action by the Holder of any Notes shall bind the Holder of every
Note issued upon the



                                       53
<PAGE>   61

registration thereof or in exchange therefor or in lieu thereof, in respect of
anything done, omitted or suffered to be done by the Indenture Trustee or the
Issuer in reliance thereon, whether or not notation of such action is made upon
such Note.

        SECTION 11.04 Notices to Indenture Trustee, Issuer and Rating Agencies.
Any request, demand, authorization, direction, notice, consent, waiver or Action
of Noteholders or other documents provided or permitted by this Indenture shall
be in writing and if such request, demand, authorization, direction, notice,
consent, waiver or Action of Noteholders is to be made upon, given or furnished
to or filed with:

        (a) the Indenture Trustee by any Noteholder or by the Issuer, it shall
be sufficient for every purpose hereunder if made, given, furnished or filed in
writing to or with the Indenture Trustee at its Corporate Trust Office, or

        (b) the Issuer by the Indenture Trustee or by any Noteholder, it shall
be sufficient for every purpose hereunder if in writing and mailed first-class,
postage prepaid to the Issuer addressed to: Nissan Auto Receivables 2001-B Owner
Trust, c/o Wilmington Trust Company, Rodney Square North, 1100 North Market
Street, Wilmington, Delaware 19890, Attention: Nissan Auto Receivables 2001-B
Owner Trust, with a copy to Nissan Motor Acceptance Corporation, 990 West 190th
Street, Torrance, California 90502, Attention: Secretary, or at any other
address previously furnished in writing to the Indenture Trustee by the Issuer
or the Administrator. The Issuer shall promptly transmit any notice received by
it from the Noteholders to the Indenture Trustee.

        Notices required to be given to the Rating Agencies by the Issuer, the
Indenture Trustee or the Owner Trustee shall be in writing, personally delivered
or mailed by certified mail, return receipt requested, to (i) in the case of
Moody's, at the following address: Moody's Investors Service, Inc., ABS
Monitoring Department, 99 Church Street, New York, New York 10007, and (ii) in
the case of Standard & Poor's, at the following address: Standard & Poor's
Ratings Services, a Division of the McGraw-Hill Companies Inc., 55 Water Street,
New York, New York 10041-0003, Attention: Asset Backed Surveillance Department,
or as to each of the foregoing, at such other address as shall be designated by
written notice to the other parties.

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

        Where this Indenture provides for notice in any manner, such notice may
be waived in writing by any Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Noteholders shall be filed



                                       54
<PAGE>   62

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

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

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

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

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

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

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

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

        SECTION 11.10 Severability. If any one or more of the covenants,
agreements, provisions or terms of this Indenture shall be for any reason
whatsoever held invalid or unenforceable in any jurisdiction, then such
covenants, agreements, provisions or terms shall be deemed severable from the
remaining covenants, agreements, provisions or terms of this Indenture and shall
in no way affect the validity or enforceability of the other provisions of this
Indenture or of the Notes or the Certificates or the rights of the Holders
thereof.

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

        SECTION 11.13 Counterparts. This Indenture may be executed
simultaneously in any number of counterparts, each of which shall be deemed to
be an original, and all of which shall constitute but one and the same
instrument.

        SECTION 11.14 Recording of Indenture. If this Indenture is subject to
recording in any appropriate public recording offices, such recording is to be
effected by the Issuer and at its expense accompanied by an Opinion of Counsel
(which may be counsel to the Indenture Trustee or any other counsel reasonably
acceptable to the Indenture Trustee) to the effect that such recording is
necessary either for the protection of the Noteholders or any other Person
secured hereunder or for the enforcement of any right or remedy granted to the
Indenture Trustee under this Indenture.

        SECTION 11.15 Trust Obligation. No recourse may be taken, directly or
indirectly, with respect to the obligations of the Issuer, the Owner Trustee or
the Indenture Trustee on the Notes or Certificates or under this Indenture or
any certificate or other writing delivered in connection herewith or therewith,
against (i) the Indenture Trustee or the Owner Trustee in its individual
capacity, (ii) the Seller, any Certificateholder or other owner of a beneficial
interest in the Issuer or (iii) any partner, owner, beneficiary, agent, officer,
director, employee or agent of the Indenture Trustee or the Owner Trustee in its
individual capacity, any Certificateholder or other owner of a beneficial
interest in the Issuer, the Owner Trustee or the Indenture Trustee or of any
successor or assign of the Indenture Trustee or the Owner Trustee in its
individual capacity, except as any such Person may have expressly agreed (it
being understood that the Indenture Trustee and the Owner Trustee have no such
obligations in their individual capacity) and except that any such partner,
owner or beneficiary shall be fully liable, to the extent provided by applicable
law, for any unpaid consideration for stock, unpaid capital contribution or
failure to pay any installment or call owing to such entity. For all purposes of
this Indenture, in the performance of any duties or obligations of the Issuer
hereunder, the Owner Trustee shall be subject to, and entitled to the benefits
of, the terms and provisions of Article VI, VII and VIII of the Trust Agreement.

        SECTION 11.16 No Petition. The 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 file, join in any filing of, or cooperate or
encourage others to file against the Seller or the Issuer any bankruptcy,
reorganization, arrangement, insolvency or liquidation proceedings, or other
proceedings under any United States federal or state bankruptcy or similar



                                       56
<PAGE>   64

law, in connection with any obligations relating to the Notes, the Certificates
or any of the Basic Documents.

        SECTION 11.17 Inspection. The Issuer agrees that, on reasonable prior
notice, it will permit any representative of the Indenture Trustee, during the
Issuer's normal business hours, to examine all the books of account, records,
reports and other papers of the Issuer, to make copies and extracts therefrom,
to cause (at the expense of the requesting party) such books to be audited by
Independent certified public accountants, and to discuss the Issuer's affairs,
finances and accounts with the Issuer's officers, employees, and Independent
certified public accountants, all at such reasonable times and as often as may
be reasonably requested. The Indenture Trustee shall and shall cause its
representatives to hold in confidence all such information except to the extent
disclosure may be required by law (and all reasonable applications for
confidential treatment are unavailing) and except to the extent that the
Indenture Trustee may reasonably determine that such disclosure is consistent
with its obligations hereunder.

        This Note is one of a duly authorized issue of Notes of the Issuer,
designated as [____]% Asset Backed Notes, Class [A-1][A-2][A-3][A-4] (herein
called the "Class [A-1][A-2][A-3][A-4] Notes"), all issued under the Indenture,
to which Indentures 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 Class
[A-1][A-2][A-3][A-4] Notes are subject to all terms of the Indenture.

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

        Principal of the Class [A-1][A-2][A-3][A-4] Notes will be payable on
each Distribution Date in an amount described in the Indenture. "Distribution
Date" means the fifteenth day of each month, or, if any such date is not a
Business Day, the next succeeding Business Day, commencing May 15, 2001.

        Notwithstanding the foregoing, the entire unpaid principal amount of the
Notes shall be due and payable on the date on which an Event of Default shall
have occurred and be continuing and the Indenture Trustee or the Holders of a
majority of the Outstanding Amount of the Notes, voting as a single class
(excluding for such purpose the outstanding principal amount of any Notes held
of record or beneficially owned by NARC II, NMAC or any of their Affiliates,
unless at such time all of the Notes are held of record or beneficially owned by
NARC II, NMAC or any of their Affiliates), have declared the Notes to be
immediately due and payable in the manner provided in Section 5.02 of the
Indenture or following the exercise by the Servicer of its option to purchase
the Receivables pursuant to Section 9.01 of the Sale and Servicing Agreement and
Section 10.01 of the Indenture. In case of an Event of Default, all interest and
principal payments will be made (1) first to the holders of the Class A-1 Notes,
until the outstanding principal balance of the Class A-1 Notes has been paid in
full, and (2) then to the holders of the Class A-2 Notes, the Class A-3 Notes
and the Class A-4 Notes on a pro rata basis (x) with respect to interest, based
on the respective aggregate amounts of interest due to these classes of notes
and (y) with respect to principal, based on the respective outstanding principal
balances of those classes of notes, until the outstanding principal balances of
those classes of notes have been paid in full. In case of the optional purchase
of the Receivables, all interest and principal payments on the Class
[A-1][A-2][A-3][A-4] Notes shall be made pro rata to the Class
[A-1][A-2][A-3][A-4] Noteholders entitled thereto.

        Payments of interest on this Note due and payable on each Distribution
Date, together with the installment of principal, if any, to the extent not in
full payment of this Note, shall be paid to the Person in whose name of such
Note (or one or more Predecessor Notes) is registered on the Record Date by wire
transfer in immediately available funds to the account designated by such
nominee, except for the final installment of principal payable with respect to
such Note on a Distribution Date or on the applicable Final Scheduled
Distribution Date, which shall be payable as provided below. Any reduction in
the principal amount of this Note (or any one or more Predecessor Notes)
effected by any payments made on any Distribution Date shall be binding upon all
future Holders of this Note and of any Note issued upon the registration of
transfer hereof or in exchange hereof or in lieu hereof, whether or not noted
hereon. If funds are expected to be available, as provided in the Indenture, for
payment in full of the then remaining



                                      A-5

unpaid principal amount of this Note on a Distribution Date, then the Indenture
Trustee, in the name of and on behalf of the Issuer, will notify the Person who
was the Registered Holder hereof as of the Record Date preceding such
Distribution Date by notice mailed or transmitted by facsimile prior to such
Distribution Date, and the amount then due and payable shall be payable only
upon presentation and surrender of this Note at the Indenture Trustee's
principal Corporate Trust Office or at the office of the Indenture Trustee's
agent appointed for such purposes located in The City of New York.

        The Issuer shall pay interest on overdue installments of interest at the
Class [A-1][A-2][A-3][A-4] Rate to the extent lawful.

        As provided in the Indenture and subject to certain limitations set
forth therein, the transfer of this Note may be registered on the Note Register
upon surrender of this Note for registration of transfer at the office or agency
designated by the Issuer pursuant to the Indenture, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Indenture Trustee as set forth in Section 2.04 of the Indenture, and thereupon
one or more new Notes of authorized denominations and in the same aggregate
principal amount will be issued to the designated transferee or transferees. No
service charge will be charged for any registration of transfer or exchange of
this Note, but the transferor may be required to pay a sum sufficient to cover
any tax or other governmental charge that may be imposed in connection with any
such registration of transfer or exchange.

        Each Noteholder or Note Owner, by acceptance of a Note or, in the case
of a Note Owner, a beneficial interest in a Note, covenants and agrees that no
recourse may be taken, directly or indirectly, with respect to the obligations
of the Issuer, the Owner Trustee or the Indenture Trustee on the Notes or under
the Indenture or any certificate or other writing delivered in connection
therewith, against (i) the Indenture Trustee or the Owner Trustee in its
individual capacity, (ii) the Seller or any owner of a beneficial interest in
the Issuer or (iii) any partner, owner, beneficiary, agent, officer, director or
employee of the Indenture Trustee or the Owner Trustee in its individual
capacity, any holder of a beneficial interest in the Issuer, the Owner Trustee
or the Indenture Trustee or of any successor or assign of the Indenture Trustee
or the Owner Trustee in its individual capacity, except as any such Person may
have expressly agreed (it being understood that the Indenture Trustee and the
Owner Trustee have no such obligations in their individual capacity) and except
that any such partner, owner or beneficiary shall be fully liable, to the extent
provided by applicable law, for any unpaid consideration for stock, unpaid
capital contribution or failure to pay any installment or call owing to such
entity.

        The Holder of this Note by its acceptance hereof agrees that, except as
expressly provided in the Basic Documents, in the case of an Event of Default
under the Indenture, the Holder shall have no claim against any of the foregoing
for any deficiency, loss or claim therefrom; provided, however, that nothing
contained herein shall be taken to prevent recourse to, and enforcement against,
the assets of the Issuer for any and all liabilities, obligations and
undertakings contained in the Indenture or in this Note.

        Each Noteholder or Note Owner, by acceptance of a Note or, in the case
of a Note Owner, a beneficial interest in a Note, covenants and agrees by
accepting the benefits of the Indenture that such Noteholder or Note Owner will
not at any time file, join in the filing of, or



                                      A-6

cooperate with or encourage others to file against the Seller or the Issuer, any
bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings
under any United States federal or state bankruptcy or similar law in connection
with any obligations relating to the Notes, the Indenture or the Basic
Documents.

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

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

        The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Holders of the Notes under the Indenture at any
time by the Issuer and the Indenture Trustee, when authorized by an Issuer
Order, with prior notice to the Rating Agencies and with the consent of the
Holders of a majority of the Outstanding Amount of the Notes, voting as a single
class (excluding for such purpose the outstanding principal amount of any Notes
held of record or beneficially owned by NARC II, NMAC or any of their
Affiliates, unless at such time all of the Notes are held of record or
beneficially owned by NARC II, NMAC or any of their Affiliates). Section 5.12 of
the Indenture also contains provisions permitting the Holders of a majority of
the Outstanding Amount of the Notes, voting as a single class (excluding for
such purpose the outstanding principal amount of any Notes held of record or
beneficially owned by NARC II, NMAC or any of their Affiliates, unless at such
time all of the Notes are held of record or beneficially owned by NARC II, NMAC
or any of their Affiliates), on behalf of the Holders of all the Notes, to waive
compliance by the Issuer with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences. Any such consent or
waiver by the Holder of this Note (or any one or more Predecessor Notes) shall
be conclusive and binding upon such Holder and upon all future Holders of this
Note and of any Note issued upon the registration of transfer hereof or in
exchange hereof or in lieu hereof whether or not notation of such consent or
waiver is made upon this Note. The Indenture also permits the Indenture Trustee
to amend or waive certain terms and conditions set forth in the Indenture
without the consent of Holders of the Notes issued thereunder.

        The term "Issuer" as used in this Note includes any successor to the
Issuer under the Indenture.

        The Issuer is permitted by the Indenture, under certain circumstances,
to merge or consolidate, subject to the rights of the Indenture Trustee and the
Holders of Notes under the Indenture.
