                                   DEFINITIONS

shall refer to the applicable Article or Section of this 2004-A SUBI Supplement,
(v) the term "include" and all variations thereof shall mean "include without
limitation," (vi) the term "or" shall include "and/or", and (vii) the term

      Any reference in this 2004-A SUBI Supplement to any agreement means such
agreement as it may be amended, restated, supplemented (only to the extent such
agreement as supplemented relates to the Notes), or otherwise modified from time
to time. Any reference in this 2004-A SUBI Supplement to any law, statute,

                                 ARTICLE TWELVE
                           CREATION OF THE 2004-A SUBI

      Section 12.01. Creation of 2004-A SUBI Assets and the 2004-A SUBI.

      (a) Pursuant to Section 3.01(a) of the Titling Trust Agreement, the UTI
Beneficiary directs the Trustee to create, and the Trustee hereby creates, one
Sub-Trust which shall be known as the "2004-A SUBI." The 2004-A SUBI shall
represent a special unit of beneficial interest solely in the 2004-A SUBI
Assets.

      (b) Pursuant to Section 3.01(a) of the Titling Trust Agreement, the UTI
Beneficiary hereby directs the Trustee to identify and allocate or to cause to
be identified and allocated to the 2004-A SUBI on the books and records of the
Titling Trust a separate Sub-Trust of Trust Assets consisting of 2004-A Eligible
Leases and the related Leased Vehicles and other associated Trust Assets owned
by the Titling Trust and not allocated to any Other SUBI or reserved for
allocation to any Other SUBI (or owned or acquired by the Trustee on behalf of
the Titling Trust but not yet allocated to, or reserved for allocation to, any
specific Sub-Trust). Such Trust Assets (the "2004-A SUBI Assets") shall be
accounted for and held in trust independently from all other Trust Assets within
the Titling Trust. Based upon their identification and allocation by the
Servicer pursuant to the 2004-A Servicing Supplement, the Trustee hereby
identifies and allocates as 2004-A SUBI Assets the 2004-A Leases and 2004-A
Vehicles more particularly described on the Schedule of 2004-A Leases and 2004-A
Vehicles and the related Trust Assets described above, each such 2004-A SUBI
Asset to be identified on the books and accounts of the Titling Trust as being
allocated to the 2004-A SUBI.

      (c) The Titling Trust is hereby granted the power and authority and is
authorized, and the Trustee is authorized on behalf of the Titling Trust, to
execute, deliver and perform its obligations under the Basic Documents.

                                                                 SUBI Supplement

      Section 12.02. Transfer of 2004-A SUBI Interests.

      (a) Interests in the 2004-A SUBI may not be transferred or assigned by the
UTI Beneficiary, and any such purported transfer or assignment shall be deemed
null, void, and of no effect herewith; provided, however, that the 2004-A SUBI
Certificate and the interests in the 2004-A SUBI represented thereby may be (i)
sold to the Transferor pursuant to the SUBI Certificate Transfer Agreement, (ii)
sold, transferred and assigned by the Transferor absolutely, or transferred and
assigned or a security interest therein granted, in connection with a
Securitized Financing, (iii) transferred to the Indenture Trustee or any
subsequent Registered Pledgee to itself or any other Person following the
occurrence of an Indenture Default (which has not been rescinded) or any similar
term in any subsequent Securitized Financing secured by the 2004-A SUBI
Certificate or any interest therein and (iv) transferred to each direct or
indirect permitted transferee of the Indenture Trustee or such subsequent
Registered Pledgee, in each case in the circumstances contemplated in, and
subject to the conditions set forth in, Section 3.04(b) of the Titling Trust
Agreement. Each such transfer shall be registrable upon surrender of the 2004-A
SUBI Certificate to be transferred for registration of the transfer at the
corporate trust office of the Trustee (or the Trust Agent, if applicable),
accompanied by a written instrument of transfer in form satisfactory to the
Trustee duly executed by the Holder thereof or such Holder's attorney duly
authorized in writing, and thereupon a new 2004-A SUBI Certificate of a like
aggregate fractional undivided interest will be issued to the designated
permitted transferee.

      (b) For any transfer of the 2004-A SUBI Certificate or an interest therein
to be effective, on or prior to the date of any absolute sale, transfer, or
assignment, the related transferee must execute and deliver to the Trustee the
non-petition covenant and the agreement required pursuant to Section 3.04(b) of
the Titling Trust Agreement.

      Section 12.03. Issuance and Form of 2004-A SUBI Certificate.

      (a) The 2004-A SUBI shall be represented by a 2004-A SUBI Certificate that
shall represent a 100% beneficial interest in the 2004-A SUBI and the 2004-A
SUBI Assets, as further set forth herein. The 2004-A SUBI Certificate shall,
upon transfer to the Trust, be registered in the name of the Trust, representing
the beneficial interest in the 2004-A SUBI Assets allocated from the UTI. The
Trustee shall register a pledge of the 2004-A SUBI Certificate in favor of the
Indenture Trustee (for the benefit of the holders of the Notes), as provided in
Article Thirteen, and shall deliver the 2004-A SUBI Certificate to the Indenture
Trustee. The 2004-A SUBI Certificate shall be substantially in the form of
Exhibit B attached hereto, with such appropriate insertions, omissions,
substitutions and other variations as are required by this 2004-A SUBI
Supplement and may have such letters, numbers or other marks of identification
and such legends and endorsements placed thereon as may, consistently herewith
and with the Titling Trust Agreement, be directed by the UTI Beneficiary. Any
portion of any 2004-A SUBI Certificate may be set forth on the reverse thereof,
in which case the following reference to the portion of the text on the reverse
shall be inserted on the face thereof, in relative proximity to and prior to the
signature of the Trustee executing such 2004-A SUBI Certificate:

                                                                 SUBI Supplement

                                       4
<PAGE>

            Reference is hereby made to the further provisions of this
            certificate set forth on the reverse hereof, which provisions shall
            for all purposes have the same effect as if set forth at this place.

      In addition, the 2004-A SUBI Certificate will bear a legend to the
following effect:

            THIS 2004-A SUBI CERTIFICATE HAS NOT BEEN AND WILL NOT BE REGISTERED
      UNDER THE SECURITIES ACT OF 1933, AS AMENDED ("THE SECURITIES ACT"), OR
      UNDER ANY STATE SECURITIES OR BLUE SKY LAW. THE HOLDER HEREOF, BY
      PURCHASING THIS 2004-A SUBI CERTIFICATE, AGREES THAT THIS 2004-A SUBI
      CERTIFICATE MAY BE REOFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED
      ONLY IN COMPLIANCE WITH THE SECURITIES ACT AND OTHER APPLICABLE LAWS,
      INCLUDING PURSUANT TO RULE 144A UNDER THE SECURITIES ACT ("RULE 144A") TO
      AN INSTITUTIONAL INVESTOR THAT THE HOLDER REASONABLY BELIEVES IS A
      QUALIFIED INSTITUTIONAL BUYER WITHIN THE MEANING OF RULE 144A (A "QIB"),
      PURCHASING FOR ITS OWN ACCOUNT OR A QIB PURCHASING FOR THE ACCOUNT OF A
      QIB, WHOM THE HOLDER HAS INFORMED, IN EACH CASE, THAT THE REOFFER, RESALE,
      PLEDGE OR OTHER TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A AND IN
      ACCORDANCE WITH ALL APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED
      STATES OR ANY OTHER APPLICABLE JURISDICTIONS.

      The 2004-A SUBI Certificate shall be printed, lithographed, typewritten,
mimeographed, photocopied, or otherwise produced or may be produced in any other
manner as may, consistently herewith and with the Titling Trust Agreement, be
determined by the UTI Beneficiary. The 2004-A SUBI Certificate and the interest
in the 2004-A SUBI evidenced thereby shall constitute a "security" within the
meaning of Section 8-102(a)(15) of the UCC and a "certificated security" within
the meaning of Section 8-102(a)(4) of the UCC.

      (b) If (i) the 2004-A SUBI Certificate is mutilated and surrendered to the
Trustee, or the Trustee receives evidence to its satisfaction of the
destruction, loss, or theft of the 2004-A SUBI Certificate, and (ii) there is
delivered to the Trustee such security or indemnity as may reasonably be
required by it to hold the Trust and the Trustee, as applicable, harmless, then
the Trustee shall execute and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost, or stolen 2004-A SUBI Certificate, a replacement
2004-A SUBI Certificate. Every 2004-A SUBI Certificate issued pursuant to this
Section 12.03(b) in replacement of any mutilated, destroyed, lost, or stolen
2004-A SUBI Certificate shall constitute an original additional contractual
obligation of the Trust, whether or not the mutilated, destroyed, lost, or
stolen 2004-A SUBI Certificate shall be at any time enforceable by anyone, and
shall be entitled to all of the benefits of the SUBI Trust Agreement equally and
proportionately with any and all other 2004-A SUBI Certificates duly issued
hereunder. The provisions of this Section 12.03(b) are exclusive and preclude
(to the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost, or stolen 2004-A SUBI
Certificates.

                                                                 SUBI Supplement

      Section 12.04. Actions and Filings. The UTI Beneficiary and the Trustee
shall undertake all other and future actions and activities as may be deemed
reasonably necessary by the Servicer pursuant to the Servicing Agreement to
perfect (or evidence) and confirm the foregoing allocations of Trust Assets to
the 2004-A SUBI, including filing or causing to be filed UCC financing
statements and executing and delivering all related filings, documents or
writings as may be deemed reasonably necessary by the Servicer or the Registered
Pledgee hereunder or under any other Basic Document. The UTI Beneficiary hereby
irrevocably makes and appoints each of the Trustee and the Servicer, and any of
their respective officers, employees, or agents, as the true and lawful
attorney-in-fact of the UTI Beneficiary (which appointment is coupled with an
interest and is irrevocable) with power to sign on behalf of the UTI Beneficiary
any financing statements, continuation statements, security agreements,
mortgages, assignments, affidavits, letters of authority, notices, or similar
documents necessary or appropriate to be executed or filed pursuant to this
Section.

      Section 12.05. Termination of the 2004-A SUBI.

      (a) In connection with any purchase by the Servicer of the corpus of the
Trust pursuant to Article Nine of the Trust Agreement, the succession of the
Servicer to the interest in the 2004-A SUBI represented by the 2004-A SUBI
Certificate, or should all of the interest in the 2004-A SUBI thereafter be held
by the UTI Beneficiary or the Holders of the UTI Certificates, whether by
transfer, sale, or otherwise, then upon the direction of such Holders, the
2004-A SUBI shall be terminated, the 2004-A SUBI Certificate shall be returned
to the Trustee and canceled, and the Servicer shall reallocate all 2004-A SUBI
Assets to the UTI.

      (b) So long as the Notes are Outstanding, the 2004-A SUBI shall not be
dissolved unless (a) required by law or (b) at the direction of the Holder of
the 2004-A SUBI Certificate (but only with the consent of the Registered
Pledgee); provided, however, that upon the sale of the Trust Estate pursuant to
Section 5.04 of the Indenture, this 2004-A SUBI Supplement shall terminate and
the 2004-A SUBI shall be terminated; provided further, that such termination
shall affect the Titling Trust only insofar as such termination relates to the
2004-A SUBI. Such termination shall not entitle the legal representatives of the
2004-A SUBI or any Holder of a 2004-A SUBI Certificate to take any action for a
partition or winding up of the Titling Trust or any Trust Assets except with
respect to the 2004-A SUBI Assets and the rights, obligations and Liabilities of
the parties hereto shall not otherwise be affected. In connection with the sale
of the Trust Estate pursuant to Section 5.04 of the Indenture, the Registered
Pledgee shall have the right to direct the Holder of the 2004-A SUBI Certificate
to dissolve the 2004-A SUBI in accordance with the provisions of the Indenture,
and the 2004-A SUBI Assets shall be distributed out of the Titling Trust at the
direction of the Holder of the 2004-A SUBI Certificate acting in accordance with
instructions from the Registered Pledgee, and the purchaser shall take delivery
of such 2004-A SUBI Assets. The Trustee and the other parties hereto shall
cooperate with the Owner Trustee or the Trustee, as applicable, to cause the
related 2004-A Vehicles to be retitled as directed by the purchaser. The
proceeds of such sale shall be distributed in the following amounts and
priority:

                                                                 SUBI Supplement

                                       6

            (i) to the Indenture Trustee, all amounts required to be paid under
      Section 6.07 of the Indenture, or to the Owner Trustee, all amounts
      required to be paid under Section 8.01 of the Trust Agreement, as the case
      may be;

            (ii) to the Servicer, any Payment Date Advance Reimbursement;

            (iii) to the Servicer, amounts due in respect of unpaid Servicing
      Fees; and

            (iv) to the Certificate Distribution Account (or, if the Lien of the
      Indenture is outstanding, the Note Distribution Account) to be distributed
      pursuant to Section 5.04(b) of the Indenture.

      Section 12.06. Representations and Warranties of Trustee. The Trustee
hereby reaffirms, as of the Cutoff Date, the representations, warranties and
covenants set forth in Section 5.12 of the Titling Trust Agreement, on which the
Grantor and UTI Beneficiary, each of its permitted assignees, and each Holder or
Related Beneficiary of a 2004-A SUBI Certificate (and beneficial owner of any
portion thereof, including the Trust and the Trust Certificateholders) may rely.
For purposes of this Section, any reference in Section 5.12 of the Titling Trust
Agreement to the Titling Trust Agreement shall be deemed to constitute
references to the SUBI Trust Agreement.

      Section 12.07. Transfer and Assignment of Certificates. For purposes of
the SUBI Trust Agreement, the third sentence of Section 3.04(b) of the Titling
Trust Agreement is hereby amended to read as follows:

      Notwithstanding the foregoing, prior to becoming the Registered Pledgee or
Holder of a SUBI Certificate or otherwise becoming entitled to distributions or
any other rights hereunder, the related transferee, assignee, or pledgee in each
case must (i) give a non-petition covenant substantially similar to that set
forth in Section 8.08 of the Titling Trust Agreement and (ii) execute an
agreement in favor of each Holder from time to time of a UTI Certificate and any
certificate evidencing an Other SUBI to release all Claims to the UTI Assets and
the related Other SUBI Assets, respectively, and, if such release is not given
effect, to subordinate fully all Claims it may be deemed to have against the UTI
Assets or such Other SUBI Assets, as the case may be.

      For so long as the 2004-A SUBI Certificate remains outstanding, each
Supplement shall contain a similar amendment with respect to such Section.

shall be made as described in the Servicing Agreement.

      (b) On each Deposit Date and Payment Date, pursuant to the instructions
from the Servicer, the Trustee (acting through the Trust Agent) shall make

                            MISCELLANEOUS PROVISIONS

      Section 15.01. Amendment.

      (a) This 2004-A SUBI Supplement (and, accordingly, the Titling Trust
Agreement as it relates to the 2004-A SUBI) may be amended by the parties
hereto:

            (i) without the consent of the Holders, to cure any ambiguity, to
      correct or supplement any provision herein that may be inconsistent with
      any other provision herein, to add any other provision with respect to
      matters or questions arising hereunder that is not inconsistent with the
      SUBI Trust Agreement, or to add or amend any provision herein to assure
      that none of the Titling Trust, the Trust, or the Transferor will be
      classified as an association (or a publicly traded partnership) taxable as
      a corporation for federal income tax purposes; provided that any such
      action will not, in the good faith judgment of the parties hereto,
      materially and adversely affect the interest of any Holder; and

            (ii) from time to time (including to change the manner in which the
      Reserve Account is funded or to eliminate the Reserve Account, or to
      change the remittance schedule for depositing SUBI Collections and other
      amounts into the 2004-A SUBI Collection Account), provided that (A) each
      Rating Agency receives prior written notice of such amendment and (B) an
      Opinion of Counsel is delivered to the Trustee to the effect that after
      such amendment, for federal income tax purposes, the Titling Trust will
      not be treated as an association (or a publicly traded partnership)
      taxable as a corporation and the Notes will properly be characterized as
      indebtedness that is secured by the assets of the Trust. To the extent
      that any such amendment materially affects the UTI or any Other SUBI, the
      2004-A SUBI Certificate or the 2004-A SUBI Assets, such amendment shall
      require the consent of the Holders affected thereby; in addition, to the
      extent that (A) such amendment shall increase or reduce in any manner the
      amount of, or accelerate or delay the timing of, collections or payments
      in respect of the 2004-A SUBI or the 2004-A SUBI Certificate or
      distributions (or the interest thereon) required to be made on any Notes
      or the Trust Certificates or reduce the Interest Rate of any Note or (B)
      reduce the percentage of the aggregate principal amount of the Notes and
      Trust Certificates required to consent to any such amendment, any such
      amendment shall require the consent of all the Holders and holders of 100%
      of all outstanding Notes and Trust Certificates --- (which for this
      purpose shall include Trust Certificates held by the Trust, the
      Transferor, the Servicer and their respective Affiliates), and an Opinion
      of Counsel as set forth in clause (B) above.

                                                                 SUBI Supplement

covenants, agreements, provisions, or terms of this 2004-A SUBI Supplement
(including any amendment hereto) shall be for any reason whatsoever held
invalid, then such covenants, agreements, provisions, or terms shall be deemed

                                                                 SUBI Supplement

      THIS CERTIFIES THAT ________________ is the registered owner of a

                                                               (SUBI Supplement)

      The Titling Trust was created pursuant to the Amended and Restated Trust
and Servicing Agreement, dated as of August 26, 1998, as amended, supplemented,
or restated from time to time (the "Titling Trust Agreement"), among NILT Trust,
as grantor and initial beneficiary (in such capacities, the "Grantor" and the
"UTI Beneficiary," respectively), NILT, Inc., as trustee (the "Trustee"), Nissan
Motor Acceptance Corporation, as servicer (the "Servicer"), Wilmington Trust
Company, as Delaware trustee (the "Delaware Trustee"), and U.S. Bank National
Association, as trust agent (the "Trust Agent").

      This certificate is a duly authorized 2004-A SUBI Certificate, and is
issued under and is subject to the terms, provisions and conditions of the
Titling Trust Agreement and the 2004-A SUBI Supplement thereto, dated as of
_________, 2004 (the "2004-A SUBI Supplement" and, together with the Titling
Trust Agreement, the "SUBI Trust Agreement"). Capitalized terms used herein that
are not otherwise defined shall have the meanings ascribed thereto in the
Agreement of Definitions, dated as of _________, 2004, by and among Nissan Auto
Lease Trust 2004-A, as issuer, NILT Trust, as Grantor and UTI Beneficiary, the
Titling Trust, Nissan Motor Acceptance Corporation, in its individual capacity,
as servicer and administrative agent, Nissan Auto Leasing LLC II, NILT, Inc., as
trustee to the Titling Trust, Wilmington Trust Company, as owner trustee and
Delaware trustee, and U.S. Bank National Association, as trust agent and
indenture trustee. By acceptance of this 2004-A SUBI Certificate, the Holder
hereof assents to the terms and conditions of the SUBI Trust Agreement and
agrees to be bound thereby. A summary of certain of the pertinent provisions of
the SUBI Trust Agreement is set forth below.

      The assets of the Titling Trust allocated to the 2004-A SUBI will
generally consist of (i) cash capital, (ii) the 2004-A Leases (iii) the 2004-A
Vehicles, (iv) certain related Trust Assets and (v) all of the Titling Trust's
rights thereunder, including the right to proceeds arising therefrom or in
connection therewith.

      Under the Titling Trust Agreement, from time to time the UTI Beneficiary
may direct the Trustee to issue to or upon the order of the UTI Beneficiary one
or more certificates (each, a "SUBI Certificate") representing a beneficial
interest in certain specified Leased Vehicles, Leases and related Trust Assets
(such assets, the "SUBI Assets"). Upon the issuance of the SUBI Certificates
relating to the SUBI Assets, the beneficial interest in the Trust and the Trust
Assets represented by the UTI shall be reduced by the amount of the Trust Assets
represented by such SUBI Certificates. This certificate was issued pursuant to
the 2004-A SUBI Supplement and represents a 100% beneficial interest in the
2004-A SUBI Assets.

      The UTI and the 2004-A SUBI shall each constitute a separate series of the
Titling Trust pursuant to Section 3806(b)(2) of the Delaware Statutory Trust Act
for which separate and distinct records shall be maintained. The 2004-A SUBI
Certificate and the interest in the 2004-A SUBI represented thereby constitutes
a "security" within the meaning of Section 8-102(a)(15) of the Delaware UCC and
a "certificated security" within the meaning of Section 8-102(a)(4) of the
Delaware UCC.

      The 2004-A SUBI Supplement may be amended by the parties thereto upon the
terms and subject to the conditions set forth in the 2004-A SUBI Supplement.

                                                                 SUBI Supplement

                                      B-2

      The Holder, by acceptance of this 2004-A SUBI Certificate, covenants and
agrees that prior to the date that is one year and one day after the date upon
which all obligations under each Securitized Financing have been paid in full,
it will not institute against, or join any other Person in instituting against,
the Grantor, the Trustee, the Titling Trust, any Beneficiary or a Special
Purpose Affiliate, any bankruptcy, reorganization, arrangement, insolvency or
liquidation Proceeding or other Proceedings under any federal or state
bankruptcy or similar law. Such covenant shall survive the termination of the
SUBI Trust Agreement, the resignation or removal of the Trustee under the SUBI
Trust Agreement or the complete or partial resignation of the Servicer under the
SUBI Trust Agreement or the Servicing Agreement.

      The Holder hereof hereby (i) expressly waives any claim it may have to any
proceeds or assets of the Trustee and to all of the Trust Assets other than
those from time to time included within the 2004-A SUBI as 2004-A SUBI Assets
and those proceeds or assets derived from or earned by such 2004-A SUBI Assets
and (ii) expressly subordinates in favor of the Holder of any certificate
evidencing an Other SUBI or a UTI Certificate any claim to any Other SUBI or UTI
Assets that, notwithstanding the waiver contained in clause (i), may be
determined to exist.

      The Trustee shall keep the certificate register with respect to this
2004-A SUBI Certificate, and the Holder of this 2004-A SUBI Certificate shall
notify the Trustee of any change of address or instructions on the distribution
of funds.

      The 2004-A SUBI shall be deemed dissolved solely with respect to the
2004-A SUBI Assets, and not as to any Trust Assets allocated to any other
Sub-Trust, upon the written direction to the Trustee by the Holder of the 2004-A
SUBI Certificate to revoke and dissolve the 2004-A SUBI. So long as the Notes
are outstanding, the 2004-A SUBI shall not be dissolved except (a) as required
by law or (b) at the direction of the Holder of the 2004-A SUBI Certificate (but
only with the consent of the Registered Pledgee); provided, however, upon any
sale of the Trust Estate pursuant to Section 5.04 of the Indenture, the
Registered Pledgee shall have the right to direct the Holder of the 2004-A SUBI
Certificate to dissolve the 2004-A SUBI in accordance with the provisions of the
Indenture. Upon such dissolution of the Titling Trust with respect to the 2004-A
SUBI and delivery of the 2004-A SUBI Certificate to the Trustee for
cancellation, the Trustee shall distribute to the Holder of the 2004-A SUBI
Certificate or its designee all 2004-A SUBI Assets and shall cause the
Certificates of Title to the 2004-A Vehicles to be issued in the name of, or at
the direction of, the Holder of the 2004-A SUBI Certificate (which may include
reallocation of the 2004-A SUBI Assets relating to the 2004-A Vehicles to the
UTI). The Holder of the 2004-A SUBI Certificate to whom such 2004-A SUBI Assets
relating to the 2004-A Vehicles are distributed shall pay or cause to be paid
all applicable titling and registration fees and taxes.

      The Titling Trust or the UTI may terminate upon the terms and subject to
the conditions set forth in the SUBI Trust Agreement.

      No SUBI or SUBI Certificate shall be transferred or assigned except to the
extent specified in the SUBI Trust Agreement or in any related Supplement and,
to the fullest extent permitted by applicable law, any such purported transfer
or assignment other than as so specified shall be deemed null, void, and of no
effect under the SUBI Trust Agreement. Notwithstanding

                                                                 SUBI Supplement

the foregoing, any SUBI Certificate and the interest in the SUBI evidenced
thereby may be (i) transferred, assigned or pledged to any Special Purpose
Affiliate or (ii) transferred, assigned or pledged by the Related Beneficiary or
a Special Purpose Affiliate to or in favor of (A) a trustee for one or more
trusts or (B) one or more other entities, in either case solely for the purpose
of securing or otherwise facilitating one or more Securitized Financings.

      This 2004-A SUBI Certificate shall be governed by and construed under the
internal laws of the State of Delaware, without reference to its conflicts of
law provisions.

      Unless this 2004-A SUBI Certificate shall have been executed by an
authorized officer of the Trustee, by manual signature, this 2004-A SUBI
Certificate shall not entitle the holder hereof to any benefit under the SUBI
Trust Agreement or be valid for any purpose.
