rule or regulation applicable to the Depositor of any court or of any federal or
state regulatory body, administrative agency or other governmental

instrumentality having jurisdiction over the Depositor or its properties: (i)

make up such shortfall before being allocated as provided in the preceding
sentence. Net losses of the Trust, if any, for any month as determined for
federal income tax purposes (and each item of income, gain, loss and deduction
entering into the computation thereof) shall be allocated to the Depositor to
the extent the Depositor has agreed hereunder and under the Sale and Servicing
Agreement and the Indenture to bear the economic burden of such net losses, and

their ownership of principal amount of Certificates as of the close of business

in this paragraph if necessary or appropriate, in its sole discretion, for the
allocations to fairly reflect the economic income, gain or loss to the Depositor

substantially in the form set forth in Exhibit A, executed by the Owner Trustee
or the Owner Trustee's authenticating agent, by manual or facsimile signature of
a Trust Officer, and such authentication shall constitute conclusive evidence,
and the only evidence, that such Certificate shall have been duly authenticated
and delivered hereunder. All Certificates shall be dated the date of their
authentication. The Wilmington Trust Company shall be the initial authenticating
agent of the Owner Trustee hereunder, and all references herein to
authentication by the Owner Trustee shall be deemed to include the
authenticating agent.

         SECTION 3.03 Registration of Transfer and Exchange of Certificates.

         (a)      The Certificate Registrar shall keep or cause to be kept, at
the office or agency maintained pursuant to Section 3.07, a Certificate Register
in which, subject to such reasonable regulations as it may prescribe, Wilmington
Trust Company shall provide for the registration of Certificates and of
transfers and exchanges of Certificates as herein provided. Wilmington Trust
Company shall be the initial Certificate Registrar. In the event that the
Certificate Registrar shall for any reason become unable to act as Certificate
Registrar, the Certificate Registrar shall promptly give written notice to such
effect to the Depositor, the Owner Trustee and the Servicer. Upon receipt of
such notice, the Servicer shall appoint another bank or trust company, which

                              (Nissan 2003-B Amended & Restated Trust Agreement)

                                       9

<PAGE>

shall agree to act in accordance with the provisions of this Agreement
applicable to it, and otherwise acceptable to the Owner Trustee, to act as
successor Certificate Registrar under this Agreement.

         (b)      Upon surrender for registration of transfer of any Certificate
at the office or agency maintained pursuant to Section 3.07, the Owner Trustee
shall execute, authenticate and deliver (or shall cause its authenticating agent
to authenticate and deliver), in the name of the designated transferee or
transferees, one or more new Certificates in authorized denominations of a like
aggregate amount dated the date of authentication by the Owner Trustee or any
authenticating agent. At the option of a Holder, Certificates may be exchanged
for other Certificates of authorized denominations of a like aggregate amount
upon surrender of the Certificates to be exchanged at the office or agency
maintained pursuant to Section 3.07. The preceding provisions of this Section
notwithstanding, the Owner Trustee shall not make and the Certificate Registrar
shall not register transfer or exchanges of Certificates for a period of 15 days
preceding the due date for any payment with respect to the Certificates.

         (c)      Every Certificate presented or surrendered for registration of
transfer or exchange shall be accompanied by a written instrument of transfer in
form satisfactory to the Owner Trustee and the Certificate Registrar duly
executed by the Holder or his attorney duly authorized in writing. Each
Certificate surrendered for registration of transfer or exchange shall be
cancelled and disposed of by the Owner Trustee in accordance with its customary
practice.

         No transfer of a Certificate shall be made unless the Owner Trustee
shall have received:

         (1)      a representation from the transferee of such Certificate
substantially in the form of Exhibit B to the effect that:

                  (i)      such transferee is not a Non-U.S. Person; and

                  (ii)     such transferee is not an employee benefit plan or
                           arrangement subject to Section 406 of Employee
                           Retirement Income Security Act of 1974, as amended
                           ("ERISA"), a plan subject to Section 4975 of the Code
                           or a governmental plan (as defined in Section 3(32)
                           of ERISA) subject to any federal, state or local law
                           which is, to a material extent, similar to the
                           foregoing provisions of ERISA or the Code (a "Plan"),
                           nor a person acting on behalf of a Plan nor using the
                           assets of a Plan to effect such transfer;

         (2)      a representation from the transferor of such Certificate
substantially in the form of Exhibit C; and

         (3)      an opinion of counsel to the Owner Trustee that the transfer
of such Certificate is being made pursuant to an effective registration under
the Securities Act or is exempt from the registration requirements of the
Securities Act.

         Notwithstanding anything else to the contrary herein, any purported
transfer of a Certificate to or on behalf of a Plan or utilizing the assets of a
Plan shall be void and of no effect.

<PAGE>

         To the extent permitted under applicable law (including, but not
limited to, ERISA), the Owner Trustee shall be under no liability to any Person
for any registration of transfer of any Certificate that is in fact not
permitted by this Section 3.03(c) or for making any payments due on such
Certificate to the Certificateholder thereof or taking any other action with
respect to such Holder under the provisions of this Trust Agreement or the Sale
and Servicing Agreement so long as the transfer was registered by the
Certificate Registrar or the Owner Trustee in accordance with the foregoing
requirements.

         (d)      No service charge shall be made for any registration of
transfer or exchange of Certificates, but the Owner Trustee or the Certificate
Registrar 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 Certificates.

         SECTION 3.04 Mutilated, Destroyed, Lost or Stolen Certificates. If (a)
any mutilated Certificate shall be surrendered to the Certificate Registrar, or
if the Certificate Registrar shall receive evidence to its satisfaction of the
destruction, loss or theft of any Certificate and (b) there shall be delivered
to the Certificate Registrar and the Owner Trustee such security or indemnity as
may be required by them to save each of them harmless, then in the absence of
notice that such Certificate shall have been acquired by a protected purchaser,
the Owner Trustee on behalf of the Trust shall execute and the Owner Trustee, or
the Owner Trustee's authenticating agent, shall authenticate and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen
Certificate, a new Certificate of like tenor and denomination. In connection
with the issuance of any new Certificate under this Section, the Owner Trustee
or the Certificate Registrar may require the payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
therewith. Any duplicate Certificate issued pursuant to this Section shall
constitute conclusive evidence of ownership in the Trust, as if originally
issued, whether or not the lost, stolen or destroyed Certificate shall be found
at any time.

         SECTION 3.05 Persons Deemed Certificateholders. Prior to due
presentation of a Certificate for registration of transfer, the Owner Trustee or
the Certificate Registrar may treat the Person in whose name any Certificate
shall be registered in the Certificate Register as the owner of such Certificate
for the purpose of receiving distributions pursuant to Section 5.02 and for all
other purposes whatsoever, and neither the Owner Trustee nor the Certificate
Registrar shall be bound by any notice to the contrary.

         SECTION 3.06 Access to List of Certificateholders' Names and Addresses.
The Certificate Registrar shall furnish or cause to be furnished to the Owner
Trustee, the Servicer or the Depositor, as the case may be, within 15 days after
its receipt of a request therefor from the Owner Trustee, the Servicer or the
Depositor in writing, a list, in such form as the Owner Trustee, the Servicer or
the Depositor may reasonably require, of the names and addresses of the
Certificateholders as of the most recent Record Date. If three or more
Certificateholders or one or more Holders of Certificates evidencing, in the
aggregate, not less than 25% of the Certificate Balance apply in writing to the
Owner Trustee, and such application states that the applicants desire to
communicate with other Certificateholders with respect to their rights under
this Agreement or under the Certificates and such application is accompanied by
a copy of the communication that such applicants propose to transmit, then the
Owner Trustee shall, within

                              (Nissan 2003-B Amended & Restated Trust Agreement)

                                       11

<PAGE>

five Business Days after the receipt of such application, afford such applicants
access during normal business hours to the current list of Certificateholders.
Each Holder, by receiving and holding a Certificate, shall be deemed to have
agreed not to hold any of the Depositor, the Servicer, the Certificate Registrar
or the Owner Trustee accountable by reason of the disclosure of its name and
address, regardless of the source from which such information was derived.

         SECTION 3.07 Maintenance of Office or Agency. The Owner Trustee shall
maintain an office or offices or agency or agencies where Certificates may be
surrendered for registration of transfer or exchange and where notices and
demands to or upon the Owner Trustee in respect of the Certificates and the
Basic Documents may be served. The Owner Trustee initially designates Wilmington
Trust Company, in such capacity, Rodney Square North, 1100 North Market Street,
Wilmington, Delaware 19890, as its principal corporate trust office for such
purposes. The Owner Trustee shall give prompt written notice to the Depositor
and to the Certificateholders of any change in the location of the Certificate
Register or any such office or agency.

         SECTION 3.08 Appointment of Paying Agent. Except during any period when
the Indenture Trustee is authorized and directed to do so under the Indenture
(i.e. prior to the termination of the Indenture), the Paying Agent shall make
distributions to Certificateholders from the Collection Account pursuant to
Section 5.02 and shall report the amounts of such distributions to the Owner
Trustee. Any Paying Agent shall have the revocable power to withdraw funds from
the Collection Account for the purpose of making the distributions referred to
above. The Owner Trustee may revoke such power and remove the Paying Agent if
the Owner Trustee determines in its sole discretion that the Paying Agent shall
have failed to perform its obligations under this Agreement in any material
respect. The Paying Agent shall initially be Wilmington Trust Company, and any
co-paying agent chosen by the Owner Trustee, and acceptable to the Owner
Trustee. The Paying Agent shall be permitted to resign as Paying Agent upon 30
days' written notice to the Indenture Trustee and, if the Paying Agent is not
the Owner Trustee, to the Owner Trustee. In the event that Wilmington Trust
Company shall no longer be the Paying Agent, the Owner Trustee shall appoint a
successor to act as Paying Agent (which shall be a bank or trust company). The
Owner Trustee shall cause such successor Paying Agent or any additional Paying
Agent appointed by the Owner Trustee to execute and deliver to the Owner Trustee
an instrument in which such successor Paying Agent or additional Paying Agent
shall agree with the Owner Trustee that as Paying Agent, such successor Paying
Agent or additional Paying Agent will hold all sums, if any, held by it for
payment to the Certificateholders in trust for the benefit of the
Certificateholders entitled thereto until such sums shall be paid to such
Certificateholders. The Paying Agent shall return all unclaimed funds to the
Owner Trustee and upon removal of a Paying Agent such Paying Agent shall also
return all funds in its possession to the Owner Trustee. The provisions of
Sections 7.01, 7.03, 7.04, 8.01 and 8.02 shall apply to the Owner Trustee also
in its role as Paying Agent, for so long as the Owner Trustee shall act as
Paying Agent and, to the extent applicable, to any other Paying Agent appointed
hereunder. Any reference in this Agreement to the Paying Agent shall include any
co-paying agent unless the context requires otherwise.

         SECTION 3.09 Ownership by the Depositor of Certificates.
Notwithstanding Section 3.03, the Depositor shall on the Closing Date receive in
accordance with Section 3.02, and shall thereafter retain beneficial and record
ownership of, Certificates representing 100% of the Certificate Balance. Any
attempted transfer of any Certificate that would reduce such interest of the
Depositor below 100% of the

                              (Nissan 2003-B Amended & Restated Trust Agreement)

                                       12

<PAGE>

Certificate Balance shall be void. The Owner Trustee shall cause one Certificate
issued to the Depositor (representing 100% of the Certificate Balance) to bear a
legend stating "THIS CERTIFICATE IS NON-TRANSFERABLE."

                                   ARTICLE IV

         SECTION 4.01 Prior Notice to Certificateholders with Respect to Certain
Matters. With respect to the following matters, the Owner Trustee shall not take

Trustee shall have notified the Certificateholders in writing of the proposed
action and none of the Certificateholders shall have notified the Owner Trustee
in writing prior to the 30th day (or such agreed upon shorter period) after such
notice is given that such Certificateholders have withheld consent or provided

         (d)      the amendment of the Indenture, whether or not by a
Supplemental Indenture, in circumstances where the consent of any Noteholder is
not required but such amendment materially adversely affects the interest of the
Certificateholders;

         (e)      the amendment, change or modification of the Administration
Agreement, other than to cure any ambiguity or to amend or supplement any
provision in a manner or add any provision that would not materially adversely

         SECTION 4.02 Action by Certificateholders with Respect to Certain

Agreement, (b) appoint a successor Administrator pursuant to Section 8 of the
Administration Agreement, (c) remove the Servicer pursuant to Section 8.01 of
the Sale and Servicing Agreement or (d) except as expressly provided in the
Basic Documents, sell the Receivables after the termination of the Indenture.
The Owner Trustee shall take the actions referred to in the preceding sentence
only upon written instructions signed by the authorized representative of 100%
of the Certificateholders.

         SECTION 4.03 Action with Respect to Bankruptcy. The Owner Trustee shall
not have the power to commence a voluntary proceeding in bankruptcy relating to
the Trust without the unanimous prior approval of all Certificateholders
(including the Board of Directors (including the Independent Directors, as such
term is defined in the Depositor's Certificate of Incorporation) of the
Depositor) and the delivery to the Owner Trustee of a written certification by
each Certificateholder that such Certificateholder reasonably believes that the
Trust is insolvent.

         SECTION 4.04 Restrictions on Certificateholders' Power. The
Certificateholders shall not direct the Owner Trustee to take or refrain from
taking any action if such action or inaction would be contrary to any
obligations of the Trust or of the Owner Trustee under any of the Basic
Documents or would be contrary to Section 2.03 nor shall the Owner Trustee be
obligated to follow any such direction, if given.

         SECTION 4.05 Majority of the Certificates Control. Except as otherwise
expressly provided herein, any action that may be taken by the
Certificateholders under this Agreement may be taken by the Holders of the

Except as expressly provided herein, any written notice of the
Certificateholders delivered pursuant to this Agreement shall be effective if
signed by Holders of the Certificates evidencing not less than a majority of the
Certificate Balance at the time of the delivery of such notice.

                   Application of Trust Funds; Certain Duties

         SECTION 5.01 Establishment of Accounts.

         (a)      On or prior to the Distribution Date on which the Notes of all
Classes have been paid in full (or substantially all of the Trust Estate is
otherwise released from the lien of the Indenture), the Owner Trustee, for the
benefit of the Certificateholders, shall establish and maintain, or shall cause
to be established and maintained, in the name of the Trust (or in such other
name as shall be specified in the Sale and Servicing Agreement), the trust
collection account (the "Trust Collection Account"). The Trust Collection
Account shall be established and maintained as an Eligible Deposit Account, and,
subject to provisions of the Sale and Servicing Agreement, bearing a designation
clearly indicating that, subject to Section 5.01(b), the funds deposited therein
are held by the Trust for the benefit of the Certificateholders, in each case in
accordance with Section 5.01 of the Sale and Servicing Agreement.

<PAGE>

         Subject to Section 5.01(b), the Owner Trustee shall possess all right,
title and interest in all funds on deposit from time to time in the Trust
Collection Account and in all proceeds thereof (other than any net investment
earnings on Eligible Investments held therein). Except as otherwise expressly
provided herein, the Trust Collection Account shall be under the sole dominion
and control of the Owner Trustee for the benefit of the Certificateholders. If,
at any time, the Trust Collection Account ceases to be an Eligible Deposit
Account, the Owner Trustee (or the Administrator on behalf of the Owner Trustee,
if the Trust Collection Account is not then held by the Owner Trustee or an
affiliate thereof) shall within 10 Business Days establish a new equivalent
Eligible Deposit Account and shall transfer any cash and/or any investments to
such new account.

         (b)      Concurrently with the execution and delivery of the Indenture,
the Servicer will establish and maintain, or shall cause to be established and
maintained, at the direction of the Depositor, the Collection Account in the
name of and under the control of the Indenture Trustee for the benefit of the
Securityholders in accordance with Section 5.01 of the Sale and Servicing
Agreement. The Indenture Trustee will be obligated to transfer back to the Trust
Collection Account all funds or investments held in the Collection Account
established pursuant to the Sale and Servicing Agreement on the Distribution
Date on which the Notes of all Classes have been paid in full or the Indenture
is otherwise terminated (excluding any amounts to be retained for distribution
in respect of Notes that are not promptly delivered for payment on such
Distribution Date), and to take all necessary or appropriate actions to transfer
all right, title and interest of the Indenture Trustee in such funds or
investments and all proceeds thereof to the Owner Trustee for the benefit of the
Certificateholders.

         (c)      Concurrently with the execution and delivery of the Indenture,
the Owner Trustee shall establish and maintain the Yield Supplement Account in
the name of and under the control of the Indenture Trustee for the benefit of
the Noteholders in accordance with paragraph 2 of the Yield Supplement
Agreement, Section 5.08 of the Sale and Servicing Agreement, and Section 8.02(a)
of the Indenture. On each Distribution Date, the Indenture Trustee will be
obligated to apply amounts on deposit in the Yield Supplement Account in
accordance with the terms of the Sale and Servicing Agreement and the Indenture.
The Indenture Trustee will be obligated to transfer back to the Owner Trustee,
for the benefit of the Certificateholders, all funds or investments held in the
Yield Supplement Account on the Distribution Date on which the Notes of all
Classes have been paid in full or the Indenture is otherwise terminated
(excluding any amounts to be retained for distribution in respect of Notes that
are not promptly delivered for payment on such Distribution Date), and to take
all necessary or appropriate actions to transfer all right, title and interest
of the Indenture Trustee in such funds or investments and all proceeds thereof
to the Owner Trustee for the benefit of the Certificateholders, which amounts
the Owner Trustee shall deposit into the Trust Collection Account.

         SECTION 5.02 Application of Amounts in Trust Accounts.

         (a)      For so long as any Notes are outstanding, on each Distribution
Date, the Indenture Trustee will distribute to Certificateholders, on a pro rata
basis, the amounts distributable thereto pursuant to Section 5.06 of the Sale
and Servicing Agreement and Section 3.01 of the Indenture. From and after the
date on which the Notes of all Classes have been paid in full, on each

                              (Nissan 2003-B Amended & Restated Trust Agreement)

                                       15

<PAGE>

Distribution Date, the Owner Trustee shall distribute to the Certificateholders
amounts on deposit in the Trust Collection Account that are distributable to the
Certificateholders in accordance with the instructions of the Servicer pursuant
to Section 5.06 of the Sale and Servicing Agreement. Upon the release from the
Lien of the Indenture of amounts on deposit in the Collection Account or any
other portion of the Owner Trust Estate, the Owner Trustee will cause such
property to be properly deposited into the Trust Collection Account under the
control of the Owner Trustee pursuant to Section 5.01(a) or distributed to the
Certificateholders in accordance with the provisions of this Agreement, as the
case may be.

         (b)      On each Distribution Date, the Owner Trustee shall send to
each Certificateholder the statement provided to the Owner Trustee by the
Servicer pursuant to Section 5.09 of the Sale and Servicing Agreement with
respect to such Distribution Date.

         (c)      In the event that any withholding tax is imposed on the
Trust's payment (or allocations of income) to a Certificateholder, such tax
shall reduce the amount otherwise distributable to the Certificateholder in
accordance with this Section. The Owner Trustee is hereby authorized and
directed to retain from amounts otherwise distributable to the
Certificateholders sufficient funds for the payment of any tax that is legally
owed by the Trust (but such authorization shall not prevent the Owner Trustee
from contesting any such tax in appropriate proceedings, and withholding payment
of such tax, if permitted by law, pending the outcome of such proceedings). The
amount of any withholding tax imposed with respect to a Certificateholder shall
be treated as cash distributed to such Certificateholder at the time it is
withheld by the Trust and remitted to the appropriate taxing authority. If there
is a possibility that withholding tax is payable with respect to any
distribution (such as any distribution to a Non-U.S. Person), the Owner Trustee
may in its sole discretion withhold such amounts in accordance with this
paragraph (c). In the event that a Certificateholder wishes to apply for a
refund of any such withholding tax, the Owner Trustee shall reasonably cooperate
with such Certificateholder in making such claim so long as such
Certificateholder agrees to reimburse the Owner Trustee for any out-of-pocket
expenses incurred.

         (d)      The Trust may, from time to time, at its option, and as
directed by the Certificateholders pursuant to Section 6.03 of this Agreement
and as provided in Section 5.11 of the Sale and Servicing Agreement, enter into
a currency Swap Agreement with a Swap Counterparty to swap amounts payable to
Certificateholders from U.S. dollars to Japanese yen; provided, that (1) at the
time the Trust enters into the Swap Agreement, the rating agencies have
confirmed the then-existing ratings of the Notes, and (2) any payments to the
Swap Counterparty (including termination payments) are payable only from amounts
that are otherwise payable to the Certificateholders. If the Certificateholders
notify the Administrator with respect to the Trust's election to enter into such
a Swap Agreement, the Administrator will prepare all necessary and appropriate
documentation and take all of the necessary and appropriate actions to cause the
Issuer to enter into such a Swap Agreement on behalf of the Trust. Any payments
received by the Issuer from the Swap Counterparty under such a Swap Agreement
shall not be deposited in the Collection Account and shall be paid by the
Indenture Trustee directly to or to the order of the Certificateholders on the
related Distribution Date.

                                                                  (Nissan 2003-B

<PAGE>

         SECTION 5.03 Method of Payment. Subject to Section 9.01(c),
distributions required to be made to Certificateholders on any Distribution Date
shall be made to each Certificateholder of record on the related Record Date
either by check mailed to such Certificateholder at the address of such holder
appearing in the Certificate Register or by wire transfer, in immediately
available funds, to the account of any Certificateholder at a bank or other
entity having appropriate facilities therefor, if such Certificateholder shall
have provided to the Certificate Registrar appropriate written instructions at
least five Business Days prior to such Distribution Date.

         SECTION 5.04 Accounting and Reports to the Noteholders,
Certificateholders, the Internal Revenue Service and Others. The Administrator
on behalf of the Trust shall (a) maintain (or cause to be maintained) the books
of the Trust on a fiscal year basis or a calendar basis on the accrual method of
accounting, (b) deliver to each Certificateholder, as may be required by the
Code and applicable Treasury Regulations, such information as may be required
(excluding Schedule K-1) to enable each Certificateholder to prepare its federal
and state income tax returns, (c) file any tax and information returns, and
fulfill any other reporting requirements, relating to the Trust, as may be
required by the Code and applicable Treasury Regulations (including Treasury
Regulation Section 1.6049-7), (d) for any period during which the beneficial
ownership interests in the Trust are held by more than one Person, make such
elections as may from time to time be required or appropriate under any
applicable state or federal statute or rule or regulation thereunder so as to
maintain the Trust's characterization as a partnership for federal income tax
purposes, (e) cause such tax returns to be signed in the manner required by law,
and (f) collect or cause to be collected any withholding tax as described in and
in accordance with Section 5.02(c) with respect to income or distributions to
Certificateholders. The Administrator on behalf of the Trust shall elect under
Section 1278 of the Code to include in income currently any market discount that
accrues with respect to the Receivables. The Administrator on behalf of the
Trust shall not make the election provided under Section 754 of the Code.
Notwithstanding anything to the contrary stated herein, the Owner Trustee shall
be exclusively responsible for the mailing of the Schedule K-1's necessary to
enable each Certificateholder to prepare its federal and state income returns.

         SECTION 5.05 Signature on Returns; Tax Matter Partner.

         (a)      The Administrator on behalf of the Trust shall sign on behalf
of the Trust the tax returns of the Trust, unless applicable law requires a
Certificateholder to sign such documents, in which case such documents shall be
signed by the Administrator, pursuant to the power-of-attorney granted thereto
pursuant to Section 2.04.

         (b)      For any period during which the beneficial ownership interests
of the Trust are held by more than one Person, the Certificateholder holding
Certificates evidencing the largest portion of the Original Certificate Balance
shall be designated the "tax matters partner" of the Trust pursuant to Section
6231(a)(7)(A) of the Code and applicable Treasury Regulations, but hereby

                      Authority and Duties of Owner Trustee

         SECTION 6.01 General Authority. The Owner Trustee is authorized and
directed to execute and deliver the Basic Documents to which the Trust is to be
a party and each certificate or other document attached as an exhibit to or
contemplated by the Basic Documents to which the Trust is to be a party and any
amendment thereto, and, on behalf of the Trust, to direct the Indenture Trustee
to authenticate and deliver Class A-1 Notes in the aggregate principal amount of
$333,000,000, Class A-2 Notes in the aggregate principal amount of $222,000,000,
Class A-3 Notes in the aggregate principal amount of $450,000,000 and Class A-4
Notes in the aggregate principal amount of $219,400,000. In addition to the
foregoing, the Owner Trustee is authorized, but shall not be obligated, to take
all actions required of the Trust, pursuant to the Basic Documents.

         SECTION 6.02 General Duties. It shall be the duty of the Owner Trustee
to discharge (or cause to be discharged) all of its responsibilities pursuant to
the terms of this Agreement and the Basic Documents to which the Trust is a
party and to administer the Trust in accordance with the provisions hereof and
of the Basic Documents and in the interest of the Certificateholders.
Notwithstanding the foregoing, the Owner Trustee shall be deemed to have
discharged its duties and responsibilities hereunder and under the Basic
Documents to the extent the Administrator has agreed in the Administration
Agreement to perform any act or to discharge any duty of the Owner Trustee
hereunder or under any Basic Document, and the Owner Trustee shall not be held
liable for the default or failure of the Administrator to carry out such
obligations or fulfill such duties under the Administration Agreement.

         SECTION 6.03 Duties of the Owner Trustee.

         (a)      Subject to Article IV and in accordance with the terms of the
Basic Documents, the Certificateholders may by written instruction direct the
Owner Trustee in the management of the Trust. Such direction may be exercised at
any time by written instruction of the Certificateholders pursuant to Article
IV. The Owner Trustee accepts the trusts hereby created and agrees to perform
its duties hereunder with respect to such trusts but only upon the terms of this
Agreement. The Owner Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to the Owner Trustee that shall be specifically required to be furnished
pursuant to any provision of this Agreement, shall examine them to determine
whether they conform on their face to the requirements of this Agreement.

         (b)      No provision of this Agreement shall be construed to relieve
the Owner 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 Owner Trustee shall
         be determined solely by the express provisions of this Agreement, the
         Owner Trustee shall not be liable except for the performance of such
         duties and obligations as are specifically set forth in this

                                                                  (Nissan 2003-B

<PAGE>

         Agreement, no implied covenants or obligations shall be read into this
         Agreement against the Owner Trustee, the permissive right of the Owner
         Trustee to do things enumerated in this Agreement shall not be
         construed as a duty and, in the absence of bad faith on the part of the
         Owner Trustee, the Owner 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 Owner
         Trustee and conforming on their face to the requirements of this
         Agreement;

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

                  (iii)    the Owner 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 the Holders of the
         Certificates representing at least a majority of the Certificate
         Balance (or such larger or smaller percentage of the Certificate
         Balance as may be required by any other provision of this Agreement or
         the other Basic Documents), the Servicer, the Administrator or the
         Indenture Trustee.

         (c)      The Owner 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 Agreement, 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 Owner Trustee regarding the
Obligors and the Receivables contained in the Trust, whether upon the exercise
of its rights under this Agreement or otherwise, shall be maintained by the
Owner 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 or is required to be made to regulators, auditors or other
governmental authorities.

         (e)      Pursuant to Section 3.02 of the Sale and Servicing Agreement,
in the event that the Owner Trustee discovers that a representation or warranty
made by the Seller pursuant to Section 3.01 or 6.01 of the Sale and Servicing
Agreement 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 the interests of any Securityholder in such
Receivable, the Owner Trustee shall give prompt written notice to the Servicer,
the Depositor and the Indenture Trustee of such incorrectness. Pursuant to
Section 4.06 of the Sale and Servicing Agreement, in the event that the Owner
Trustee discovers that any covenant of the Servicer set forth in the second
sentence of Section 4.01 or Section 4.02 or 4.05 of the Sale and Servicing
Agreement has been breached by the Servicer, the Owner Trustee shall give prompt
written notice to the Servicer, the Depositor and the Indenture Trustee of such
breach.

                                                                  (Nissan 2003-B

         SECTION 6.04 No Duties Except as Specified in this Agreement or in
Instructions. The Owner Trustee shall not have any duty or obligation to manage,
make any payment with respect to, register, record, sell, dispose of, or
otherwise deal with the Owner Trust Estate, or to otherwise take or refrain from
taking any action under, or in connection with, any Basic Document to which the
Owner Trustee is a party or otherwise contemplated hereby, except as expressly
provided by the terms of this Agreement, any Basic Document to which the Trust
is a party or in any document or written instruction received by the Owner
Trustee pursuant to Section 6.03. No implied duties or obligations shall be read
into this Agreement or any Basic Document against the Owner Trustee. The Owner
Trustee shall have no responsibility for filing any financing or continuation
statement in any public office at any time or otherwise to perfect or maintain
the perfection of any security interest or lien granted to it hereunder or to
prepare or file any Securities and Exchange Commission filing for the Trust or
to record this Agreement or any Basic Document. Notwithstanding anything to the
contrary herein or in any Basic Document, the Owner Trustee shall not be
required to execute, deliver or certify on behalf of the Trust or any other
Person any filings, certificates, affidavits or other instruments required under
the Sarbanes-Oxley Act of 2002, to the extent permitted by applicable law. The
Owner Trustee nevertheless agrees that it will, at its own cost and expense,
promptly take all action as may be necessary to discharge any liens on any part
of the Owner Trust Estate that result from actions by, or claims against, the
Owner Trustee that are not related to the ownership or the administration of the
Owner Trust Estate.

         SECTION 6.05 No Action Except Under Specified Documents or
Instructions. The Owner Trustee shall not manage, control, use, sell, dispose of
or otherwise deal with any part of the Owner Trust Estate except (i) in
accordance with the powers granted to and the authority conferred upon the Owner
Trustee pursuant to this Agreement, (ii) in accordance with the Basic Documents
and (iii) in accordance with any document or instruction delivered to the Owner
Trustee pursuant to Section 6.03.

         SECTION 6.06 Restrictions. The Owner Trustee shall not take any action
(a) that is inconsistent with the purposes of the Trust set forth in Section
2.03 or (b) that, to the actual knowledge of a Trust Officer of the Owner
Trustee, would result in the Trust's becoming taxable as a corporation for
federal income tax purposes. The Certificateholders shall not have the authority
to and, by acceptance of an ownership interest in any Certificate shall thereby
be deemed to have covenanted not to, direct the Owner Trustee to take action
that would violate the provisions of this Section.

                          Concerning the Owner Trustee

         SECTION 7.01 Rights of the Owner Trustee. Except as otherwise provided
in Article VI:

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,

                                                                  (Nissan 2003-B

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;

         (b)      the Owner Trustee shall not be liable with respect to any
action taken or omitted to be taken by it in accordance with the instructions of
the Administrator, as provided in the Administration Agreement, the Servicer or
the Indenture Trustee, or the Certificateholders, as provided herein;

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

         (d)      under no circumstances shall the Owner Trustee be liable for
indebtedness evidenced by or arising under any of the Basic Documents, including
the principal of and interest on the Notes;

         (e)      the Owner 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 Certificates representing not less than 25% of the
Certificate Balance; provided, however, that if the payment within a reasonable
time to the Owner Trustee of the costs, expenses or liabilities likely to be
incurred by it in the making of such investigation is, in the opinion of the
Owner Trustee, not reasonably assured to the Owner Trustee by the security
afforded to it by the terms of this Agreement, the Owner 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 Owner 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

         (f)      the Owner Trustee shall not be liable for the default or
misconduct of the Administrator, the Servicer, the Depositor or the Indenture
Trustee under any of the Basic Documents or otherwise, and the Owner Trustee
shall have no obligation or liability to perform the obligations of the Trust or
any other Person (including the Owner Trustee) under the Basic Documents that
are required to be performed by the Administrator under the Administration
Agreement, the Indenture Trustee under the Indenture or the Servicer under the
Sale and Servicing Agreement.

         SECTION 7.02 Furnishing of Documents. The Owner Trustee shall furnish
to the Certificateholders promptly upon receipt of a written request therefor,
duplicates or copies of all reports, notices, requests, demands, certificates,

<PAGE>

         SECTION 7.03 Representations and Warranties. The Owner Trustee hereby
represents and warrants to the Depositor and for the benefit of the
Certificateholders, that:

         (a)      It is a banking corporation duly organized and validly
existing in good standing under the laws of Delaware. It has full power, right
and authority to execute, deliver and perform its obligations under this
Agreement and each other Basic Document.

         (b)      It has taken all corporate action necessary to authorize the
execution and delivery of this Agreement and each other Basic Document, and this
Agreement and each other Basic Document has been executed and delivered by one
of its officers duly authorized to execute and deliver this Agreement and each
other Basic Document on its behalf.

         (c)      This Agreement constitutes the legal, valid and binding
obligation of the Owner Trustee, enforceable against it in accordance with its
terms except as the enforceability thereof may be limited by bankruptcy,
insolvency, moratorium, reorganization or other similar laws affecting the
enforcement of creditors' rights generally and by general principles of equity.

         (d)      It is authorized to exercise trust powers in the State of
Delaware as and to the extent contemplated herein or has appointed a Delaware
trustee that is so authorized and it has a principal place of business in the
State of Delaware or has appointed a Delaware trustee that has such a principal
place of business.

         (e)      Neither the execution nor the delivery by it of this Agreement
nor the consummation by the Owner Trustee of the transactions contemplated
hereby or thereby nor compliance by it with any of the terms or provisions
hereof or thereof will contravene any federal or Delaware law, governmental rule
or regulation governing the banking or trust powers of the Owner Trustee or any
judgment or order binding on it, or constitute any default under its charter
documents or by-laws or any indenture, mortgage, contract, agreement or
instrument to which it is a party or by which any of its properties may be
bound.

         SECTION 7.04 Reliance; Advice of Counsel.

         (a)      The Owner Trustee shall incur no liability to anyone in acting
upon any signature, instrument, notice, resolution, request, consent, order,
certificate, report, opinion, bond, or other document or paper believed by it to
be genuine and believed by it to be signed by the proper party or parties. The
Owner Trustee may accept a certified copy of a resolution of the board of
directors or other governing body of any corporate party as conclusive evidence
that such resolution has been duly adopted by such body and that the same is in
full force and effect. As to any fact or matter the method of the determination
of which is not specifically prescribed herein, the Owner Trustee may for all
purposes hereof rely on a certificate, signed by the president or any vice
president or by the treasurer or other authorized officers or agents of the
relevant party, as to such fact or matter and such certificate shall constitute
full protection to the Owner Trustee for any action taken or omitted to be taken
by it in good faith in reliance thereon.

         (b)      In the exercise or administration of the trusts hereunder and
in the performance of its duties and obligations under the Basic Documents, the
Owner Trustee (i) may act directly or

                                                                  (Nissan 2003-B

through its agents or attorneys pursuant to agreements entered into with any of
them, and the Owner Trustee shall not be liable for the conduct or misconduct of
such agents or attorneys if such agents or attorneys shall have been selected by
the Owner Trustee with reasonable care, and (ii) may consult with counsel,
accountants and other skilled persons to be selected with reasonable care and
employed by it. The Owner Trustee shall not be liable for anything done,
suffered or omitted in good faith by it in accordance with the opinion or advice
of any such counsel, accountants or other such persons and not, to the actual
knowledge of the Owner Trustee, contrary to this Agreement or any Basic
Document.

         SECTION 7.05 Not Acting in Individual Capacity. In accepting the trusts
hereby created, Wilmington Trust Company acts solely as Owner Trustee hereunder
and not in its individual capacity. Except with respect to a claim based on the
Owner Trustee's willful misconduct, bad faith or negligence, no recourse shall
be had for any claim based on any provision of this Agreement, the Notes or
Certificates, or based on rights obtained through the assignment of any of the
foregoing, against the institution serving as the Owner Trustee in its
individual capacity. The Owner Trustee shall not have any personal obligation,
liability or duty whatsoever to any Securityholder 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.

         SECTION 7.06 Owner Trustee Not Liable for Certificates or Receivables.
The Owner Trustee makes no representations as to the validity or sufficiency of
this Agreement or of the Certificates or of the Notes (other than the execution
by the Owner Trustee on behalf of the Trust of, and the certificate of
authentication on, the Certificates). The Owner Trustee shall have no obligation
to perform any of the duties of the Servicer or Administrator.

                  The Owner Trustee shall at no time have any responsibility or
liability for or with respect to the legality, validity and enforceability of
the Certificates, 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 Securityholders under this Agreement and the
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 Trust with any covenant or the
breach by the Trust of any warranty or representation made under this Agreement
or in any related document and the accuracy of any such warranty or
representation prior to the Owner Trustee's receipt of notice or other discovery
of any noncompliance therewith or any breach thereof; the acts or omissions of
the Trust or the Servicer; or any action by the Owner Trustee taken at the
instruction of the Certificateholders, provided, however, that the foregoing
shall not relieve the Owner Trustee of its obligation to perform its duties
under this Agreement.

                  The Owner Trustee shall not be accountable for the use or
application by the Issuer of any of the Certificates or of the proceeds of such
Certificates, of any of the Notes or of the

                                                                  (Nissan 2003-B

<PAGE>

proceeds of such Notes, or for the use or application of any funds paid to the
Servicer in respect of the Certificates.

         SECTION 7.07 Owner Trustee May Own Certificates and Notes. The Owner
Trustee in its individual or any other capacity may become the owner or pledgee
of Certificates or Notes and may deal with the Depositor, the Administrator, the
Indenture Trustee and the Servicer in banking or other transactions with the
same rights as it would have if it were not Owner Trustee.

         SECTION 7.08 Sales Finance Licenses. The Owner Trustee shall cause the
Trust to use its best efforts to maintain the effectiveness of all licenses
required under (a) the Pennsylvania Motor Vehicle Sales Finance Act, (b) the
Maryland Financial Institutions Article and (c) all other similar applicable
state laws (other than those of Alabama, Hawaii or Maine) in connection with
this Agreement and the Basic Documents and the transactions contemplated hereby
and thereby until such time as the Trust shall terminate in accordance with the
terms hereof.

                                  ARTICLE VIII

                          Compensation of Owner Trustee

         SECTION 8.01 Owner Trustee's Fees and Expenses. The Depositor shall pay
or shall cause the Servicer to pay to the Owner Trustee from time to time
compensation for its services as have been separately agreed upon before the
date hereof. The Depositor shall reimburse the Owner 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 Owner
Trustee's agents, counsel, accountants and experts directly related to its
services hereunder ("Expenses").

         SECTION 8.02 Indemnification. The Depositor shall cause the Servicer or
the Administrator to indemnify the Owner Trustee against any and all loss,
liability, claim, tort, penalty or Expense (including reasonable attorneys'
fees) of any kind or nature whatsoever incurred by it in connection with the
administration of the Trust and the performance of its duties hereunder. The
Owner Trustee shall notify the Administrator and the Servicer promptly of any
claim for which it may seek indemnity. Failure by the Owner Trustee to so notify
the Administrator and the Servicer shall not relieve the Depositor or the
Administrator or the Servicer of its obligations hereunder, except to the extent
such failure shall adversely affect the Depositor's or the Administrator's or
the Servicer's defenses in respect thereof. In case any such action is brought
against the Owner Trustee under this Section 8.02 and it notifies the
Administrator of the commencement thereof, the Administrator will assume the
defense thereof, with counsel reasonably satisfactory to the Owner Trustee (who
may, unless there is, as evidenced by an opinion of counsel to the Owner Trustee
stating that there is a conflict of interest, be counsel to the Administrator),
and the Administrator will not be liable to the Owner Trustee under this Section
for any legal or other expenses subsequently incurred by the Owner Trustee in
connection with the defense thereof, other than reasonable costs of
investigation. Neither the Depositor nor the Administrator nor the Servicer need
reimburse any expense or

                                                                  (Nissan 2003-B

<PAGE>

indemnify against any loss, liability or expense incurred by the Owner Trustee
through the Owner Trustee's own willful misconduct, negligence or bad faith. The
Owner Trustee's rights under this Article VIII shall survive the termination of
this Agreement or the resignation or removal of the Owner Trustee.

         SECTION 8.03 Payments to the Owner Trustee. Any amounts paid to the
Owner Trustee pursuant to this Article VIII from assets in the Owner Trust
Estate shall be deemed not to be a part of the Owner Trust Estate immediately
after such payment.

                                   ARTICLE IX

                         Termination of Trust Agreement

         SECTION 9.01 Termination of Trust Agreement.

         (a)      This Agreement (other than Article VIII) shall terminate and
the Trust shall dissolve and be wound up in accordance with Section 3808 of the
Statutory Trust Statute, upon the earliest of (i) the maturity or other
liquidation of the last Receivable (or other asset) in the Owner Trust Estate
and the final distribution of all moneys or other property or proceeds of the
Owner Trust Estate in accordance with the terms of this Agreement, the Indenture
and the Sale and Servicing Agreement (including, but not limited to, any
property and proceeds to be deposited in the Collection Account pursuant to the
terms of the Sale and Servicing Agreement or to be released by the Indenture
Trustee from the Lien of the Indenture pursuant to the terms of the Indenture),
or (ii) the election by the Servicer to purchase the corpus of the Trust
pursuant to Section 9.01 of the Sale and Servicing Agreement and the payment or
distribution to all Securityholders of all amounts required to be paid to them
under the Indenture or this Agreement. The bankruptcy, liquidation, dissolution,
death or incapacity of any Certificateholder shall not (x) operate to terminate
this Agreement or the Trust, nor (y) entitle such Certificateholder's legal
representatives or heirs to claim an accounting or to take any action or
proceeding in any court for a partition or winding up of all or any part of the
Trust or Owner Trust Estate, nor (z) otherwise affect the rights, obligations
and liabilities of the parties hereto.

         (b)      Except as provided in Section 9.01(a), neither the Depositor
nor any Certificateholder shall be entitled to revoke or terminate the Trust.

         (c)      Notice of any termination of the Trust, specifying the
Distribution Date upon which the Certificateholders shall surrender their
Certificates to the Paying Agent for payment of the final distributions and
cancellation, shall be given by the Owner Trustee to the Certificateholders

other than the Owner Trustee) at the time such notice is given to
Certificateholders. Upon presentation and surrender of the Certificates, the
Paying Agent shall cause to be distributed to Certificateholders amounts
distributable on such Distribution Date pursuant to Section 5.02.

         In the event that one or more of the Certificateholders shall not
surrender their Certificates for cancellation within six months after the date
specified in the above-mentioned written notice, the Owner Trustee shall give a
second written notice to the remaining Certificateholders to surrender their
Certificates for cancellation and receive the final distribution with respect
thereto. If within one year after the second notice all the Certificates shall
not have been surrendered for cancellation, the Owner Trustee may take
appropriate steps, or may appoint an agent to take appropriate steps, to contact
the remaining Certificateholders concerning surrender of their Certificates, and
the cost thereof shall be paid out of the funds and other assets that shall
remain subject to this Agreement. Any funds remaining in the Trust after
exhaustion of such remedies shall be distributed by the Owner Trustee to the
Depositor.

         (d)      Upon the winding up of the Trust and its termination, the
Owner Trustee shall cause the Certificate of Trust to be cancelled by filing a
certificate of cancellation with the Secretary of State in accordance with the
provisions of Section 3810 of the Statutory Trust Statute.

             Successor Owner Trustees and Additional Owner Trustees

         SECTION 10.01 Eligibility Requirements for Owner Trustee. The Owner
Trustee shall at all times be an entity having a combined capital and surplus of
at least $50,000,000 and be subject to supervision or examination by federal or
state authorities. If such entity shall publish reports of condition at least
annually, pursuant to law or to the requirements of the aforesaid supervising or
examining authority, then for the purpose of this Section 10.01, the combined
capital and surplus of such corporation shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. In case at any time the Owner Trustee shall cease to be eligible in
accordance with the provisions of this Section, the Owner Trustee shall resign
immediately in the manner and with the effect specified in Section 10.02.

         SECTION 10.02 Resignation or Removal of Owner Trustee. The Owner
Trustee may at any time resign and be discharged from the trusts hereby created
by giving written notice thereof to the Depositor, the Servicer and the
Indenture Trustee. If, for any reason, Wilmington Trust Company or any of its
Affiliates should assume the duties of the Indenture Trustee, then from that
time forward Wilmington Trust Company, in its capacity as Owner Trustee, shall
resign as Owner Trustee hereunder if any Event of Default under the Indenture
occurs and is necessary to eliminate any conflict of interest under the TIA with
the Indenture Trustee or any other trustee under the Indenture. Upon receiving
such notice of resignation, the Servicer shall promptly appoint a successor
Owner Trustee by written instrument, in duplicate, one copy of which shall be
delivered to each of the resigning Owner Trustee and the successor Owner
Trustee. If no successor Owner Trustee shall have been so appointed or shall not
have accepted such

                                                                  (Nissan 2003-B

appointment within 30 days after the giving of such notice of resignation, the
resigning Owner Trustee may petition any court of competent jurisdiction for the
appointment of a successor Owner Trustee.

         If at any time the Owner Trustee shall cease to be eligible in
accordance with the provisions of Section 10.01 and shall fail to resign
promptly, or if at any time the Owner Trustee shall be legally unable to act, or
shall be adjudged bankrupt or insolvent, or a receiver of the Owner Trustee or
of its property shall be appointed, or any public officer shall take charge or
control of the Owner Trustee or of its property or affairs for the purpose of
rehabilitation, conservation or liquidation, then the Administrator may remove
the Owner Trustee by written instrument to such effect delivered to the Owner
Trustee, the Depositor and the Indenture Trustee. If the Administrator shall
remove the Owner Trustee under the authority of the immediately preceding
sentence, the Servicer shall promptly appoint a successor Owner Trustee by
written instrument in duplicate, one copy of which instrument shall be delivered
to each of the outgoing Owner Trustee so removed and the successor Owner
Trustee, and pay all fees, expenses and other compensation owed to the outgoing
Owner Trustee.

         Any resignation or removal of the Owner Trustee and appointment of a
successor Owner Trustee pursuant to any of the provisions of this Section shall
not become effective until acceptance of appointment by the successor Owner
Trustee pursuant to Section 10.03 and payment of all fees and expenses owed to
the outgoing Owner Trustee. The Administrator shall provide notice of such
resignation or removal of the Owner Trustee to each of the Rating Agencies.

         SECTION 10.03 Successor Owner Trustee. Any successor Owner Trustee
appointed pursuant to Section 10.02 shall execute, acknowledge and deliver to
the Administrator and to its predecessor Owner Trustee an instrument accepting
such appointment under this Agreement, and thereupon the resignation or removal
of the predecessor Owner Trustee shall become effective and such successor Owner
Trustee, without any further act, deed or conveyance, shall become fully vested
with all the rights, powers, duties, and obligations of its predecessor under
this Agreement, with like effect as if originally named as Owner Trustee. The
predecessor Owner Trustee shall upon payment of its fees and expenses deliver to
the successor Owner Trustee all documents and statements and monies held by it
under this Agreement; and the Administrator and the predecessor Owner Trustee
shall execute and deliver such instruments and do such other things as may
reasonably be required for fully and certainly vesting and confirming in the
successor Owner Trustee all such rights, powers, duties, and obligations.

         No successor Owner Trustee shall accept appointment as provided in this
Section unless at the time of such acceptance such successor Owner Trustee shall
meet the criteria for eligibility set forth in Section 10.01.

         Upon acceptance of appointment by a successor Owner Trustee pursuant to
this Section, the Administrator shall mail notice of the successor of the Owner
Trustee to all Certificateholders, the Indenture Trustee, all Noteholders and
the Rating Agencies. If the Administrator fails to mail such notice within 10
days after acceptance of appointment by the

                                                                  (Nissan 2003-B

successor Owner Trustee, the successor Owner Trustee shall cause such notice to
be mailed at the expense of the Administrator.

         SECTION 10.04 Merger or Consolidation of Owner Trustee. Any corporation
into which the Owner Trustee may be merged or converted or with which it may be
consolidated or any corporation resulting from any merger, conversion or
consolidation to which the Owner Trustee shall be a party, or any corporation
succeeding to all or substantially all of the corporate trust business of the
Owner Trustee, shall be the successor of the Owner Trustee hereunder, provided
such corporation shall be eligible pursuant to Section 10.01, without the
execution or filing of any instrument or any further act on the part of any of
the parties hereto, anything herein to the contrary notwithstanding; provided,
further, that the Owner Trustee shall mail notice of such merger or
consolidation to the Rating Agencies.

         SECTION 10.05 Appointment of Co-Trustee or Separate Trustee.
Notwithstanding any other provisions of this Agreement, at any time, for the
purpose of meeting any legal requirements of any jurisdiction in which any part
of the Owner Trust Estate or any Financed Vehicle may at the time be located,
the Administrator and the Owner Trustee acting jointly shall have the power and
shall execute and deliver all instruments to appoint one or more Persons
approved by the Owner Trustee to act as co-trustee, jointly with the Owner
Trustee, or separate trustee or separate trustees, of all or any part of the
Owner Trust Estate, and to vest in such Person, in such capacity, such title to
the Trust, or any part thereof, and, subject to the other provisions of this
Section, such powers, duties, obligations, rights and trusts as the
Administrator and the Owner Trustee may consider necessary or desirable. If the
Administrator shall not have joined in such appointment within 25 days after the
receipt by it of a request so to do, the Owner Trustee alone shall have the
power to make such appointment. No co-trustee or separate trustee under this
Agreement shall be required to meet the terms of eligibility as a trustee
pursuant to Section 10.01 and no notice of the appointment of any co-trustee or
separate trustee shall be required pursuant to Section 10.03.

         Each separate trustee and co-trustee shall, to the extent permitted by
law, be appointed and act subject to the following provision and conditions:

                  (i)      all rights, powers, duties and obligations conferred
         or imposed upon the Owner Trustee shall be conferred upon and exercised
         or performed by the Owner 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 Owner
         Trustee joining in such act), except to the extent that under any law
         of any jurisdiction in which any particular act or acts are to be
         performed, the Owner Trustee shall be incompetent or unqualified to
         perform such act or acts, in which event such rights, powers, duties,
         and obligations (including the holding of title to the Trust or any
         portion thereof in any such jurisdiction) shall be exercised and
         performed singly by such separate trustee or co-trustee, but solely at
         the direction of the Owner Trustee;

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

                                                                  (Nissan 2003-B

                  (iii)    the Administrator and the Owner Trustee acting
         jointly may at any time accept the resignation of or remove any
         separate trustee or co-trustee.

         Any notice, request or other writing given to the Owner Trustee shall
be deemed to have been given to each of the then separate trustees and
co-trustees, as if given to each of them. Each separate trustee and co-trustee,
upon its acceptance of the powers and duties conferred thereto under this
Agreement, shall be vested with the estates or property specified in its
instrument of appointment, either jointly with the Owner Trustee or separately,
as may be provided therein, subject to all the provisions of this Agreement,
specifically including every provision of this Agreement relating to the conduct
of, affecting the liability of, or affording protection to, the Owner Trustee.
Each such instrument shall be filed with the Owner Trustee and a copy thereof
given to the Administrator.

         Any separate trustee or co-trustee may at any time appoint the Owner
Trustee as 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
Owner Trustee, to the extent permitted by law, without the appointment of a new
or successor trustee.

                                  Miscellaneous

         SECTION 11.01 Supplements and Amendments. This Agreement may be amended
by the Depositor and the Owner Trustee, with prior written notice to the Rating
Agencies, without the consent of any of the Noteholders or the
Certificateholders, to cure any ambiguity, to correct or supplement any
provisions in this Agreement or for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions in this Agreement or
of modifying in any manner the rights of the Noteholders or the
Certificateholders; provided, however, that such action shall not, as evidenced
by an Opinion of Counsel, adversely affect in any material respect the interests
of any Noteholder or Certificateholder.

         This Agreement may also be amended from time to time by the Depositor
and the Owner Trustee, with prior written notice to the Rating Agencies, with
the consent of the Holders of the Notes evidencing not less than a majority of
the Outstanding Amount of the Notes (excluding for such purpose Notes owned by
NARC II, NMAC or any of their Affiliates unless at such time all Notes are then
owned by NARC II, NMAC and their Affiliates) or if all of the Notes have been
paid in full, the Holders of the Certificates evidencing not less than a
majority of the Certificate Balance (excluding for such purpose Certificates
owned by NARC II, NMAC or any of their Affiliates unless at such time all
Certificates are then owned by NARC II, NMAC and their Affiliates) for the
purpose of adding any provisions to or changing in any manner or eliminating any
of the provisions of this Agreement or of modifying in any manner the rights of
the Noteholders or the Certificateholders; provided, however, that no such
amendment shall (a) increase or reduce in any manner the amount of, or
accelerate or delay the timing of, collections of payments on Receivables or
distributions that shall be required to be made for the benefit of

                                                                  (Nissan 2003-B

the Noteholders or the Certificateholders or (b) reduce the aforesaid percentage
of the Outstanding Amount of the Notes and the Certificate Balance required to
consent to any such amendment, without the consent of the Holders of all the
affected Notes and Certificates.

         Promptly after the execution of any such amendment or consent, the
Owner Trustee shall furnish written notification of the substance of such
amendment or consent to each Certificateholder, the Indenture Trustee and each
of the Rating Agencies.

         It shall not be necessary for the consent of Certificateholders, the
Noteholders or the Indenture Trustee pursuant to this Section to approve the
particular form of any proposed amendment or consent, but it shall be sufficient
if such consent shall approve the substance thereof. The manner of obtaining
such consents (and any other consents of Certificateholders provided for in this
Agreement or in any other Basic Document) and of evidencing the authorization of
the execution thereof by Certificateholders shall be subject to such reasonable
requirements as the Owner Trustee may prescribe.

         Promptly after the execution of any amendment to the Certificate of
Trust, the Owner Trustee shall cause the filing of such amendment with the
Secretary of State.

         Prior to the execution of any amendment to this Agreement or the
Certificate of Trust, the Owner Trustee shall be entitled to receive and rely
upon an Opinion of Counsel stating that the execution of such amendment is
authorized or permitted by this Agreement. The Owner Trustee may, but shall not
be obligated to, enter into any such amendment which affects the Owner Trustee's
own rights, duties or immunities under this Agreement or otherwise.

         SECTION 11.02 No Legal Title to Owner Trust Estate in
Certificateholders. The Certificateholders shall not have legal title to any
part of the Owner Trust Estate. The Certificateholders shall be entitled to
receive distributions with respect to their undivided ownership interest therein
only in accordance with Articles V and IX. No transfer, by operation of law or
otherwise, of any right, title or interest of the Certificateholders to and in
their ownership interest in the Owner Trust Estate shall operate to terminate
this Agreement or the trusts hereunder or entitle any transferee to an
accounting or to the transfer to it of legal title to any part of the Owner
Trust Estate.

         SECTION 11.03 Limitations on Rights of Others. Except for Section 2.06,
the provisions of this Agreement are solely for the benefit of the Owner
Trustee, the Depositor, the Certificateholders, the Administrator and, to the
extent expressly provided herein the Indenture Trustee and the Noteholders, and
nothing in this Agreement (other than Section 2.06), whether express or implied,
shall be construed to give to any other Person any legal or equitable right,
remedy or claim in the Owner Trust Estate or under or in respect of this
Agreement or any covenants, conditions or provisions contained herein.

October 4, 2002 (as amended and supplemented from time to time, including the
Amended and Restated Trust Agreement, dated as of June 17, 2003, the "Trust
Agreement"), between NARC II, as depositor (the "Depositor"), and Wilmington

Trust Agreement, the Indenture, dated as of June 17, 2003 (the "Indenture"),
between the Trust and Wells Fargo Bank Minnesota, National Association, as
indenture trustee (the "Indenture Trustee"), or in the Sale and Servicing
Agreement, dated as of June 17, 2003 (the "Sale and Servicing Agreement"), among
the Trust, the Depositor and NMAC, as servicer (the "Servicer"), as applicable.

         This Certificate is one of the duly authorized Certificates designated
as "Asset Backed Certificates" (the "Certificates") issued pursuant to the Trust
Agreement. Certain debt instruments evidencing obligations of the Trust have
been issued under the Indenture, consisting of four classes of Notes designated

certain insurance policies and certain other rights under the Trust Agreement
and the Sale and Servicing Agreement and all proceeds of the foregoing.

         Under the Trust Agreement, there will be distributed on the 15th day of
each month or, if such 15th day is not a Business Day, the next Business Day,
(each, a "Distribution Date"), commencing on July 15, 2003, to the person in
whose name this Certificate is registered at the close of business on the
related Record Date, such Certificateholder's pro rata portion of the amounts to
be distributed to Holders of the Certificates on such Distribution Date in
respect of amounts distributable to the Certificateholders of the Certificates
pursuant to Section 5.06 of the Sale and Servicing Agreement.

         The holder of this Certificate acknowledges and agrees that its rights
to receive distributions in respect of this Certificate are subordinated to the
rights of the Noteholders as described in the Sale and Servicing Agreement and
the Indenture.

         The holder of this Certificate acknowledges and agrees that certain
distributions made pursuant to Section 5.06 of the Sale and Servicing Agreement
to the Certificateholders may be made in Japanese yen in the event the Issuer
enters into a currency Swap Agreement as contemplated by Section 5.11 of the
Sale and Servicing Agreement. If any such election is made, an amendment to the
Sale and Servicing Agreement must be executed pursuant to Section 10.01 of the
Sale and Servicing Agreement subject to the approvals of such parties as set
forth in Section 5.11 of the Sale and Servicing Agreement, and a supplemental
Indenture must be executed pursuant to and subject to the approvals of such
parties as set forth in Section 9.01 of the Indenture. In connection with the
execution of any such Swap Agreement, the Certificateholders must provide
alternative appropriate payment instructions to the Owner Trustee and the
Indenture Trustee for the receipt of any payment in Japanese yen.

         It is the intent of the Depositor, NMAC and the Certificateholders
that, for purposes of federal income tax, state and local income tax, any state
single business tax and any other income taxes, the Trust will be treated as a
division or branch of the Person holding the beneficial ownership interests in
the Trust for any period during which the beneficial ownership interests in the
Trust are held by one person, and will be treated as a partnership, and the
Certificateholders will be treated as partners in that partnership, for any
period during which the beneficial ownership interests in the Trust are held by
more than one person. For any such period during which the beneficial ownership
interests in the Trust are held by more than one person, each Certificateholder,
by acceptance of a Certificate or any beneficial interest on a Certificate,
agrees to treat, and to take no action inconsistent with the treatment of, the
Certificates as partnership interests in the Trust for such tax purposes.

         Each Certificateholder, by its acceptance of a Certificate or any
beneficial interest in a Certificate, covenants and agrees that such
Certificateholder will not at any time institute against the Depositor or the
Trust, or join in any institution against the Depositor or the Trust of, any
bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings,
or other proceedings under any United States, federal or state bankruptcy or
similar law in connection with any obligations relating to the Certificates, the
Notes, the Trust Agreement or any of the Basic Documents.

                            (REVERSE OF CERTIFICATE)

         The Certificates do not represent an obligation of, or an interest in,
the Owner Trustee, NMAC, NARC II, Nissan North America, Inc. or any of their
Affiliates and no recourse may be had against such parties or their assets,
except as may be expressly set forth or contemplated herein or in the Trust
Agreement or the Basic Documents. In addition, this Certificate is not
guaranteed by any governmental agency or instrumentality and is limited in right
of payment to certain collections with respect to the Receivables (and certain
other amounts), all as more specifically set forth in the Trust Agreement and in
the Sale and Servicing Agreement. A copy of each of the Sale and Servicing
Agreement and the Trust Agreement may be examined during normal business hours
at the principal office of the Depositor, and at such other places, if any,
designated by the Depositor, by any Certificateholder upon written request.

         The Trust Agreement permits, with certain exceptions therein provided,
the amendment thereof and the modification of the rights and obligations of the
Depositor and the rights of the Certificateholders under the Trust Agreement at
any time by the Depositor and the Owner Trustee, with the consent of the Holders
of the Notes representing a majority of the Outstanding Amount of the Notes, or,
if all of the Notes have been paid in full, with the consent of the Holders of
the Certificates representing a majority of the Certificate Balance (excluding,
in each case, Securities held by NARC II, NMAC or any of their Affiliates unless
at such time all Notes or Certificates, as the case may be, are then owned by
NARC II, NMAC and their Affiliates). Any such consent by the holder of this
Certificate shall be conclusive and binding on such holder and on all future
holders of this Certificate and of any Certificate issued upon the transfer
hereof or in exchange herefor or in lieu hereof whether or not notation of such
consent is made upon this Certificate or such replacement certificate. The Trust
Agreement also permits the amendment thereof, in certain limited circumstances,
without the consent of the Holders of the Certificates or the Notes.

         As provided in the Trust Agreement, and subject to certain limitations
therein set forth, the transfer of this Certificate is registerable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies of the Certificate Registrar maintained by
the Owner Trustee, accompanied by a written instrument of transfer in form
satisfactory to the Owner Trustee and the Certificate Registrar duly executed by
the holder hereof or such holder's attorney duly authorized in writing, and
thereupon one or more new Certificates of authorized denominations evidencing
the same aggregate interest in the Trust will be issued to the designated
transferee or transferees. The initial Certificate Registrar appointed under the
Trust Agreement is Wilmington Trust Company, Rodney Square North, 1100 North
Market Street, Wilmington, Delaware 19890.

         The Certificates are issuable only as registered Certificates without
coupons in denominations of $1,000.00 and in integral multiples of $0.01 in
excess thereof. As provided in the Trust Agreement and subject to certain
limitations therein set forth, Certificates are exchangeable for new
Certificates of authorized denominations evidencing the same aggregate
denomination, as requested by the holder surrendering the same. No service
charge will be made for any such registration of transfer or exchange, but the
Owner Trustee or the Certificate

                                                                  (Nissan 2003-B

Registrar may require payment of a sum sufficient to cover any tax or
governmental charge payable in connection therewith.

         The Owner Trustee, the Certificate Registrar and any agent of the Owner
Trustee or the Certificate Registrar may treat the person in whose name this
Certificate is registered as the owner hereof for all purposes and none of the
Owner Trustee, the Certificate Registrar or any such agent shall be affected by
any notice to the contrary.

         The obligations and responsibilities created by the Trust Agreement and
the Trust created thereby shall terminate upon the payment to Certificateholders
of all amounts required to be paid to them pursuant to the Trust Agreement and
the Sale and Servicing Agreement and the disposition of all property held as
part of the Owner Trust Estate. NMAC, as servicer of the Receivables under the
Sale and Servicing Agreement, or any successor servicer, may at its option
purchase the corpus of the Trust at a price specified in the Sale and Servicing
Agreement, and any such purchase of the Receivables and other property of the
Trust will effect early retirement of the Certificates; however, such right of
purchase is exercisable only after the last day of the Collection Period as of
which the Pool Balance is less than or equal to 5% of the Original Pool Balance.

                                                                  (Nissan 2003-B
