Trustee is required to prepare, file or deliver pursuant to the Related
Documents, and at the request of the Owner Trustee shall take all appropriate
action that the Trust or the Owner Trustee is required to take pursuant to the

         (h)      In carrying out the foregoing duties or any of its other
obligations under this Agreement, the Administrative Agent may enter into
transactions or otherwise deal with any of its Affiliates; provided, however,
that the terms of any such transactions or dealings shall be in accordance with

<PAGE>

                  (ii)     the initiation of any claim or lawsuit by the Trust

                  (iii)    the amendment, change or modification of the Related
Documents;

                  (iv)     the appointment of successor Note Registrars,

Indenture or the appointment of successor Administrative Agents or successor
Servicers, or the consent to the assignment by the Note Registrar, any Paying
Agent or Indenture Trustee of its obligations under the Indenture;

                  (v)      the removal of the Indenture Trustee; and

                  (vi)     the provision to the Rating Agencies copies of any

Agent shall not be obligated to, and shall not, (i) make any payments to the
Noteholders under the Related Documents, (ii) sell the Owner Trust Estate
pursuant to Section 5.02 of the Indenture, (iii) take any other action that the
Trust directs the Administrative Agent not to take on its behalf or (iv) take
any other action which may be construed as having the effect of varying the
investment of the Trust Certificateholders.

                  1.03     Records. The Administrative Agent shall maintain
appropriate books of account and records relating to services performed
hereunder, which books of account and records shall be accessible for inspection
by the Trust and the Transferor at any time during normal business hours.

                  1.04     Compensation. As compensation for the performance of
the Administrative Agent's obligations under this Agreement and as reimbursement
for its expenses related thereto, the Administrative Agent shall be entitled to
an annual payment of compensation which shall be solely an obligation of the
Servicer.

                  1.05     Additional Information to be Furnished to the Trust.
The Administrative Agent shall furnish to the Trust from time to time such
additional information regarding the Collateral as the Trust shall reasonably
request.

                  1.06     Independence of the Administrative Agent. For all
purposes of this Agreement, the Administrative Agent shall be an independent
contractor and shall not be subject to the supervision of the Trust or the Owner
Trustee with respect to the manner in which it accomplishes the performance of
its obligations hereunder. Unless expressly authorized by the Trust, the
Administrative Agent shall have no authority to act for or represent the Trust
or the Owner Trustee in any way and shall not otherwise be deemed an agent of
the Trust or the Owner Trustee.

Owner Trustee as members of any partnership, joint venture, association,
syndicate, unincorporated business or other separate entity, (ii) shall be
construed to impose any liability as such on any of them or (iii) shall be
deemed to confer on any of them any express, implied or apparent authority to

                  1.08     Other Activities of Administrative Agent. Nothing
herein shall prevent the Administrative Agent or its Affiliates from engaging in
other businesses or, in its sole discretion, from acting in a similar capacity
as an Administrative Agent for any other Person or entity, even though such
person or entity may engage in business activities similar to those of the
Trust, the Owner Trustee or the Indenture Trustee.

                  1.09     Term of Agreement; Resignation and Removal of

                  1.12     Amendments. This Agreement may be amended from time
to time by a written amendment duly executed and delivered by the parties
hereto, with the written consent of the Owner Trustee but without the consent of
the Securityholders, 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 Securityholders; provided, that such
amendment will not, in the Opinion of Counsel satisfactory to the Indenture
Trustee, materially and adversely affect the interest of any Noteholder or Trust
Certificateholder. This Agreement may also be amended by the parties hereto with
the written consent of the Owner Trustee and the holders of Notes evidencing at
least a majority of the Outstanding Amount and the holders of Trust Certificates
evidencing at least a majority of the Certificate Balance for the purpose of

consented to in writing by the Trust and the Owner Trustee and subject to the
satisfaction of the Rating Agency Condition in respect thereof. An assignment
with such consent and satisfaction, if accepted by the assignee, shall bind the
assignee hereunder in the same manner as the Administrative Agent is bound
hereunder. Notwithstanding the foregoing, this Agreement may be assigned by the
Administrative Agent without the consent of the Trust or the Owner Trustee to a
corporation or other organization that is a successor (by merger, consolidation
or purchase of assets) to the Administrative Agent; provided, that such
successor organization executes and delivers to the Trust, the Owner Trustee and
the Indenture Trustee an agreement, in form and substance reasonably
satisfactory to the Owner Trustee and the Indenture Trustee, in which such
corporation or other organization agrees to be bound hereunder by the terms of
said assignment in the same manner as the Administrative Agent is bound
hereunder. Subject to the foregoing, this Agreement shall bind any successors or
assigns of the parties hereto.

General Obligations Law of the State of New York).

invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

the certificates, notices or agreements delivered pursuant hereto, as to all of
which recourse shall be had solely to the assets of the Trust.

                  1.19     Third-Party Beneficiary. The Owner Trustee is a

         WHEREAS, NILT Trust, as Grantor and UTI Beneficiary, NMAC, as Servicer,
Wilmington Trust Company, as Delaware Trustee, NILT, Inc., as Trustee, and U.S.
Bank, as Trust Agent, have entered into an amended and restated trust and
servicing agreement, dated as of August 26, 1998 (the "Titling Trust
Agreement"), pursuant to which the Titling Trust was created to, among other
things, take assignments and conveyances of and hold in trust various assets
(the "Trust Assets");

         WHEREAS, the parties to the Titling Trust Agreement supplemented the

2003 (together with the Titling Trust Agreement, the "SUBI Trust Agreement"), to
establish a special unit of beneficial interest, the "2003-A SUBI" ("2003-A

         WHEREAS, in connection with the SUBI Trust Agreement a separate
portfolio of leases (the "2003-A Leases"), the vehicles that are leased under
the 2003-A Leases (the "2003-A Vehicles"), and certain other related Trust
Assets have been allocated to the 2003-A SUBI;

interest in the 2003-A SUBI Certificate to the Indenture Trustee to secure
payment of the Notes;

provide that if, for any reason, the form of any of the transactions
contemplated by the SUBI Trust Agreement, the 2003-A SUBI Certificate, the Trust
Agreement, the SUBI Certificate Transfer Agreement, the Trust SUBI Certificate
Transfer Agreement or the Indenture (collectively, the "Transfer Documents") is

Transferor and the Trust shall be deemed to have granted to the Indenture
Trustee a first priority security interest in such assets to secure the Notes.

         NOW, THEREFORE, in consideration of the mutual agreements herein
contained, and of other good and valuable consideration, the receipt and
adequacy of which are hereby acknowledged, the parties hereto agree as follows:
