claim to any proceeds or assets of the Titling Trust or to any of the Trust
Assets other than the 2005-A SUBI Assets and any present or future proceeds

         2.02 Certificate of Title. None of the parties hereto, including the

Certificate of Title for any 2005-A Vehicle to reflect the back-up Lien created

                                 MISCELLANEOUS

         3.01 Amendments.

         (a) Any term or provision of this Agreement may be amended by the
parties hereto, without the consent of any other Person; provided that (i)
either (A) any amendment that materially and adversely affects the interests of
the Noteholders shall require the consent of Noteholders evidencing not less
than a Majority Interest of the Notes voting together as a single class or (B)
such amendment shall not, as evidenced by an Officer's Certificate of the
Servicer or the Transferor delivered to the Indenture Trustee, materially and
adversely affect the interests of the Noteholders and (ii) any amendment that
adversely affects the interests of the Trust Certificateholders, the Indenture
Trustee or the Owner Trustee shall require the prior written consent of the
Persons whose interests are adversely affected. An amendment shall be deemed not
to materially and adversely affect the interests of the Noteholders if the
Rating Agency Condition is satisfied with respect to such amendment and the
Officer's Certificate described in the preceding sentence is provided to the
Indenture Trustee. The consent of the Trust Certificateholders or the Owner
Trustee shall be deemed to have been given if the Servicer does not receive a
written objection from such Person within 10 Business Days after a written
request for such consent shall have been given. The Indenture Trustee may, but
shall not be obligated to, enter into or consent to any such amendment that
affects the Indenture Trustee's own rights, duties, liabilities or immunities
under this Agreement or otherwise.

         (b) It shall not be necessary for the consent of any Person pursuant to
this Section for such Person to approve the particular form of any proposed
amendment, but it shall be sufficient if such Person consents to the substance
thereof.

         (c) Notwithstanding the foregoing, no amendment shall (i) reduce the
interest rate or principal amount of any Note, or change the due date of any
installment of principal of or interest in any Note, or the Redemption Price
with respect thereto, without the consent of the Holder of such Note or (ii)
reduce the Outstanding Amount, the Holders of which are required to consent to
any matter without the consent of the Holders of at least a Majority Interest of
the Notes which were required to consent to such matter before giving effect to
such amendment.

         (d) Notwithstanding anything herein to the contrary, any term or
provision of this Agreement may be amended by the Servicer or the Transferor
without the consent of any of the Noteholders or any other Person to add, modify
or eliminate any provisions as may be necessary or advisable in order to comply
with or obtain more favorable treatment under or with respect to any law or
regulation or any accounting rule or principle (whether now or in the future in
effect); it being a condition to any such amendment that the Rating Agency
Condition shall have been satisfied. The Officer's Certificate described in
Section 3.01(b)(i)(B) is delivered to the Indenture Trustee.

          (e) Not less than 15 days prior to the execution of any amendment to
this Agreement, the Servicer shall provide each Rating Agency, the Trust
Certificateholder, the Transferor, the Owner Trustee and the Indenture Trustee
with written notice of the substance of such amendment. No later than 10
Business Days after the execution of any amendment to this Agreement, the
Servicer shall furnish a copy of such amendment to each Rating Agency, the Trust
Certificateholders, the Indenture Trustee and the Owner Trustee.


         (f) None of U.S. Bank National Association, as trustee of NILT Trust
and as Trust Agent, NILT, Inc., nor the Indenture Trustee shall be under any
obligation to ascertain whether a Rating Agency Condition has been satisfied
with respect to any amendment. When the Rating Agency Condition is satisfied
with respect to such amendment, the Servicer shall deliver to a Responsible
Officer of the Indenture Trustee and U.S. Bank National Association, an
Officer's Certificate to that effect, and U.S. Bank National Association and the
Indenture Trustee may conclusively rely upon the Officer's Certificate from the
Servicer that a Rating Agency Condition has been satisfied with respect to such
amendment.


         3.02 Governing Law. This Agreement shall be governed by and construed
in accordance with the laws of the State of New York, without reference to its
conflict of law provisions (other than Section 5-1401 of the General Obligations
law of the State of New York).

         3.03 Severability of Provisions. If any one or more of the covenants,
agreements, provisions or terms of this Agreement shall be for any reason
whatsoever held invalid or unenforceable, then such covenants, agreements,
provisions or terms shall be deemed severable from the remaining covenants,
agreements, provisions and terms of this Agreement, as the same may be amended
or supplemented, and shall in no way affect the validity or enforceability of
the other covenants, agreements, provisions or terms of this Agreement.

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

         3.05 Successors and Assigns. All covenants and agreements contained in
this Agreement shall be binding upon, and inure to the benefit of, the parties
hereto and their respective successors and permitted assigns.

         3.06 Further Assurances. Each party will perform such acts and execute
and deliver to any other party such additional documents or instruments as may
be reasonably requested in order to effect the purposes of this Agreement and to
