                                 ARTICLE EIGHT

               SERVICING OF THE 2003-A LEASES AND 2003-A VEHICLES

         Section 8.01 Identification of 2003-A Leases and 2003-A Vehicles;
Securitization Value. The Servicer hereby identifies and allocates as 2003-A
SUBI Assets the Leased Vehicles and the Leases relating to such Leased Vehicles
more particularly described in the Schedule of 2003-A Leases and 2003-A Vehicles
(respectively, the "2003-A Vehicles" and the "2003-A Leases"). The Servicer
shall calculate the Securitization Value for each 2003-A Lease as of the Cutoff
Date.

         Section 8.02 Reallocation and Repurchase of 2003-A Leases and 2003-A
Vehicles; Purchase of Matured Vehicles.

         (a)      (i) If the Servicer grants an extension with respect to any
2003-A Lease, the Servicer shall, on the related Deposit Date, (A) deposit or
cause to be deposited into the 2003-A SUBI Collection Account an amount equal to
the Repurchase Payment and (B) direct the Trustee

                                                            Servicing Supplement

                                       2

to either reallocate such 2003-A Lease and the related 2003-A Vehicle from the
2003-A SUBI to the UTI or cause such 2003-A Lease and 2003-A Vehicle to be
conveyed to the Servicer; and (ii) if a Lessee changes the domicile of or title
to a 2003-A Vehicle and such change would be likely to result in the Titling
Trust doing business in a Restricted Jurisdiction, the Titling Trust, or the
Trustee on behalf of the Titling Trust, shall, as an obligation of the Titling
Trust and at the direction of the Servicer, on the related Deposit Date, (A)
deposit or cause to be deposited into the 2003-A SUBI Collection Account, from
amounts held by the Titling Trust, an amount equal to the Repurchase Payment and
(B) either reallocate such 2003-A Lease and the related 2003-A Vehicle from the
2003-A SUBI to the UTI or cause such 2003-A Lease and 2003-A Vehicle to be
conveyed to the Servicer.

         (b)      The Servicer hereby makes to the other parties hereto and the
parties to the SUBI Trust Agreement the representations and warranties contained
in Section 2.06(a) of the Basic Servicing Agreement as to each 2003-A Lease and
2003-A Vehicle as of the Vehicle Representation Date. The Servicer also hereby
represents and warrants that (i) each 2003-A Lease is an 2003-A Eligible Lease,
(ii) it used no adverse selection procedures in selecting any of the 2003-A
Leases or any of the 2003-A Vehicles for allocation to the 2003-A SUBI and (iii)
it is not aware of any bias in the selection of the 2003-A Leases that would
cause delinquencies or losses on the 2003-A Leases to be worse than any other
Leases held by the Titling Trust; provided, however, that the Servicer can make
no assurance as to the actual delinquencies or losses on the 2003-A Leases or
the 2003-A Vehicles. Upon discovery by the Trustee, the Servicer, the Owner
Trustee, the Indenture Trustee or the Transferor that any representation or
warranty in this Section 8.02(b) was incorrect as of the Cutoff Date in a manner
that materially adversely affects the interest of the Trust in the related
2003-A Lease or 2003-A Vehicle, the entity discovering such incorrectness (if
other than the Servicer) shall give prompt written notice to the Servicer. On or
before the Deposit Date related to the Collection Period in which the Servicer
discovers such incorrectness (whether pursuant to such notice or otherwise), the
Servicer shall cure in all material respects the circumstance or condition with
respect to which the representation or warranty was incorrect as of the Cutoff
Date. If the Servicer is unable or unwilling to cure such circumstance or
condition by such Deposit Date, the Servicer shall (i) deposit (or cause to be
deposited) into the 2003-A SUBI Collection Account an amount equal to the
Repurchase Payment, and (ii) direct the Trustee to either reallocate such 2003-A
Lease and the related 2003-A Vehicle from the 2003-A SUBI to the UTI or cause
such 2003-A Lease and 2003-A Vehicle to be conveyed to the Servicer.

         (c)      Immediately prior to the sale or disposition of a Matured
Vehicle or a Defaulted Vehicle, the Servicer may reallocate such Matured Vehicle
or Defaulted Vehicle from the 2003-A SUBI to the UTI for purposes of
implementing NMAC's like kind exchange program. In connection with such
reallocation, NILT Trust, as the UTI Beneficiary, will cause to be deposited
into the 2003-A SUBI Collection Account the Reallocation Payments no later than
two Business Days after such reallocation, or, if the Monthly Remittance
Condition is met, the Servicer shall be permitted to retain the Reallocation
Payments received during a Collection Period until such amounts are required to
be disbursed on the next Payment Date. Upon receipt of the Reallocation
Payments, the 2003-A SUBI shall have no claim against or interest in such
Matured or Defaulted Vehicle.

<PAGE>

         (d)      In connection with the purchase by the Servicer of a Matured
Vehicle relating to a 2003-A Lease pursuant to Section 2.06(f) of the Basic
Servicing Agreement, if (i) no Sales Proceeds Advance has been made, the
purchase price of such Matured Vehicle will equal the Securitization Value of
such 2003-A Lease as of the date of expiration and (ii) a Sales Proceeds Advance
has been made, (a) the purchase price will equal the amount of the Sales
Proceeds Advance, (b) no additional amounts need be remitted by the Servicer,
and (c) the Servicer shall be deemed to have been reimbursed for such Sales
Proceeds Advance.

         (e)      If any 2003-A Lease and the related 2003-A Vehicle are
reallocated to the UTI, until such time thereafter, if ever, as such Lease and
Leased Vehicle are allocated to an Other SUBI, the Servicer shall indemnify,
defend and hold harmless the Related Beneficiaries and the Trust from and
against any and all loss or liability with respect to or resulting from such
2003-A Lease or 2003-A Vehicle (including the reasonable fees and expenses of
counsel).

         Section 8.03 Collections and Payment Date Advance Reimbursement.

         (a)      The Servicer shall, with respect to SUBI Collections and
amounts in respect of the 2003-A SUBI Certificate, from time to time, determine

                  (i)      during each Collection Period, in addition to the
         deposits required by Section 2.07 of the Basic Servicing Agreement,
         deposit into the 2003-A SUBI Collection Account all Repurchase Payments
         pursuant to Section 8.02(a) and Section 8.02(b), and any Reallocation
         Payments pursuant to Section 8.02(c);

                  (ii)     on, or prior to each Deposit Date, deposit into the
         2003-A SUBI Collection Account all Advances, any Residual Value Surplus
         from the sale of a Matured Vehicle for which the Servicer made a Sales
         Proceeds Advance and any Net Auction Proceeds from the disposition of a
         Matured Vehicle at auction for which the Servicer was reimbursed during
         the related Collection Period pursuant to Section 8.06;

                  (iii)    on or prior to each Payment Date, deposit into the
         2003-A SUBI Collection Account all Cap Payments and/or Cap Termination
         Payments; and

                  (iv)     on each Payment Date, pursuant to the related Payment
         Date Certificate, allocate Available Funds on deposit in the 2003-A
         SUBI Collection Account with respect to the related Collection Period
         and instruct the Trustee (acting through the Trust Agent) to make, no
         later than 11:00 a.m., New York City time, the following deposits and
         distributions in the following amounts and order of priority:

                           (A)      to the Servicer the sum of outstanding (1)
                  Sales Proceeds Advances (x) in respect of 2003-A Vehicles that
                  were sold during the related Collection Period (other than a
                  sale to the Servicer pursuant to Section 8.02(d)(ii)), and (y)
                  that have been outstanding as of the end of that Collection
                  Period for at least 90 days and (2) Monthly Payment Advances

                  outstanding as of the end of the Collection Period for at
                  least 90 days (collectively, the "Payment Date Advance
                  Reimbursement");

                           (B)      to or on behalf of the Servicer, the
                  Servicing Fee in respect of the related Collection Period,
                  together with any unpaid Servicing Fees in respect of one or

         (b)      Notwithstanding Section 2.07 of the Basic Servicing Agreement,
the Servicer shall be permitted to retain the amounts provided for in such
Section received during a Collection Period until such amounts are required to
be disbursed on the next Payment Date, for so long as no Servicer Default has

         Pending deposit into the 2003-A SUBI Collection Account, SUBI
Collections may be employed by the Servicer at its own risk and for its own
benefit and shall not be segregated from its own funds.

         Section 8.04. Net Deposits. Notwithstanding anything to the contrary
contained in this 2003-A Servicing Supplement, for so long as NMAC is the
Servicer, the Servicer shall be permitted to deposit into the 2003-A SUBI
Collection Account only the net amount distributable to the Trust, as holder of
the 2003-A SUBI Certificate on the related Deposit Date. The Servicer shall,
however, account to the Trust, the Trustee, the Trust Agent, the Indenture
Trustee (or any successor to the duties of the Indenture Trustee), the Owner
Trustee and the Holders of the Securities as if all of the deposits and
distributions described herein were made individually.

         Section 8.05. Servicing Compensation.

         (a)      As compensation for the performance of its obligations under
the Servicing Agreement, the Servicer shall be entitled to receive the Servicing
Fee.

         (b)      The Servicer shall also be entitled to additional servicing
compensation with respect to the 2003-A SUBI Assets in the form of, among other
things, Administrative Charges to the extent not required for the payment of
insurance premiums, taxes, or similar charges allocable to the 2003-A Leases.

         Section 8.06. Advances.

         (a)      If during a Collection Period a Lessee makes a Lessee Partial
Monthly Payment, the Servicer shall make, by deposit into the 2003-A SUBI
Collection Account on the related Deposit Date, a Monthly Payment Advance,
unless such Advance is not required to be made pursuant to Section 8.06(c).

         (b)      On each Deposit Date, the Servicer shall make, by deposit into
the 2003-A SUBI Collection Account, Sales Proceeds Advances, unless such Advance
is not required to be made pursuant to Section 8.06(c). After the Servicer has
made a Sales Proceeds Advance with respect to a Matured Vehicle, the Trust shall
have no claim against or interest in such Matured Vehicle or any Net Auction
Proceeds resulting from the sale or other disposition thereof, except with
respect to any related Residual Value Surplus. If the Servicer shall sell or
otherwise dispose of a Matured Vehicle after having made a Sales Proceeds
Advance, the Trust may retain all of such Sales Proceeds Advance, and the
Servicer shall retain the related Net Auction Proceeds up to the Securitization
Value of the related 2003-A Lease, and shall deposit the Residual Value Surplus,
if any, into the 2003-A SUBI Collection Account. If the Net Auction Proceeds are
less than the Securitization Value of the related 2003-A Lease, the Servicer may
deduct the difference from SUBI Collections in respect of one or more future
Collection Periods. If the Servicer has not sold a Matured Vehicle within 90
days after it has made a Sales Proceeds Advance, it shall be reimbursed for such
Sales Proceeds Advance from the 2003-A SUBI Collection Account. Within six
months of receiving such reimbursement, if the related 2003-A Vehicle has not
been sold, the Servicer shall, if permitted by applicable law, cause such 2003-A
Vehicle to be sold at auction and shall remit the proceeds associated with such
auction sale to the 2003-A SUBI Collection Account.

         (c)      Notwithstanding anything to the contrary in the Servicing
Agreement, the Servicer shall be required to make an Advance only to the extent
that it determines that such Advance will be recoverable from future payments on
or in respect of the related 2003-A Lease or 2003-A Vehicle.

         Section 8.07. Third Party Claims. In addition to the requirements set
forth in Section 2.14 of the Basic Servicing Agreement, the Servicer shall
immediately notify the Transferor (in the event that NMAC is not acting as
Servicer) and the Indenture Trustee (or any successor to the duties of the
Indenture Trustee) upon learning of a claim or Lien of whatever kind of a third
party

                                                            Servicing Supplement

that would materially and adversely affect the interests of the Transferor or
the Trust with respect to the 2003-A SUBI Assets.

         Section 8.08. Contingent and Excess Liability Insurance Policy. So long
as any Securities are outstanding, the Servicer shall maintain and pay when due
all premiums with respect to, and the Servicer may not terminate or cause the
termination of, the Contingent and Excess Liability Insurance Policy unless (i)
a replacement Insurance Policy is obtained that provides coverage against third
party claims that may be raised against the Titling Trust, the Trustee on behalf
of the Titling Trust or the Trust in an amount at least equal to $1 million
combined single limit per occurrence and excess coverage of $15 million combined
single limit each occurrence without limit on the number of occurrences in any
policy period (which Insurance Policy may be a blanket Insurance Policy covering
the Servicer and one or more of its Affiliates) and (ii) in the case of Rated
Securities, each Rating Agency has received prior written notification from the
Owner Trustee of such termination and any replacement insurance. The obligations
of the Servicer pursuant to this Section shall survive any termination of the
Servicer's other obligations under the Servicing Agreement until such time as
claims can no longer be brought that would be covered by such Insurance
Policies, whether as a result of the expiration of relevant statutes of
limitations or otherwise.

         Section 8.09. Reporting by the Servicer; Delivery of Certain
Documentation.

         (a)      On or prior to the Closing Date, and periodically thereafter
as required in order to update the contents thereof upon any changes in the
matters certified therein, the Servicer shall furnish to the Trustee and the
Related Beneficiary an Officer's Certificate listing the officers of the
Servicer involved in, or responsible for, the servicing of the 2003-A Leases.

         (b)      On each Calculation Date, the Servicer shall furnish to the
Trustee and each Related Beneficiary a Settlement Statement for the related
Collection Period.

         Section 8.10. Accountants' Reports. On or before the last day of the
third month after the end of the fiscal year of the Servicer, beginning with
June 30, 2004, the Servicer shall deliver or cause to be delivered to the Trust,
the Indenture Trustee, each Rating Agency and the Owner Trustee the following
reports: (a) a report that such firm has audited the consolidated financial
statements of the Servicer in accordance with generally accepted auditing
standards, that such firm is independent of the Servicer within the meaning of
the Code of Professional Ethics of the American Institute of Certified Public
Accountants ("AICPA"), and expressing such firm's opinion thereon; and (b) a
report indicating that such firm has examined, in accordance with standards
established by AICPA, management's assertion about the Servicer's compliance
with the minimum servicing standards identified in the Mortgage Bankers
Association of America's Uniform Single Attestation Program for Mortgage Bankers
("USAP") as such standards relate to automobile and light-duty truck loans
serviced for others, and expressing such firm's opinion on such management
assertion (the "Annual USAP Report") or any similar internal control audit
report that is acceptable to each Rating Agency.

         Section 8.11. Annual Officer's Certificates.

         (a)      On or before the last day of the third month after the end of
the fiscal year of the Servicer, beginning with June 30, 2004, the Servicer
shall deliver an Officer's Certificate to the Trust, the Indenture Trustee, each
Rating Agency, and the Owner Trustee in accordance with Section 3.01(c) of the
Basic Servicing Agreement.

         (b)      On or before the last day of the third month after the end of
the fiscal year of the Servicer, beginning with June 30, 2004, for as long as
NMAC continues to act as the Servicer, the Servicer shall deliver an Officer's
Certificate to each Rating Agency, the Owner Trustee and the Indenture Trustee
stating that, with respect to certain ERISA Plans maintained or sponsored by the
Servicer or any of the Servicer's ERISA affiliates: (a) Plan assets will not be
materially less than the present value of accrued benefits under each of the
Plans as of the close of the most recent Plan year, as reported in the most
recent plan financial statements; (b) neither the Servicer nor any of its ERISA
affiliates anticipates that the actuarial value of the assets of any Plan it
maintains would not be materially insufficient to cover the Gateway current
liability (as defined by the Code and demonstrated on the most recent Form 5500
Schedule B that has been filed with the IRS), or is contemplating benefit
improvements that would cause the Servicer or its ERISA affiliates to maintain a
Plan with materially underfunded Gateway current liability; (c) if all of the
Plans (other than a multiemployer Plan) were terminated (disregarding any Plans
with surpluses), the unfunded liabilities with respect to the Plans would have
no material adverse effect on Nissan Motor Co., Ltd. or Nissan North America,
Inc.; and (d) no accumulated funding deficiency or waived funding deficiency as
defined in section 412 of the Code or under any multiemployer Plan or collective
bargaining agreement exists and there is no failure to make any required
contribution under the minimum funding requirements of the Code, as of the close
of the most recent Plan year.

         Section 8.12. Servicer Defaults; Termination of Servicer.

         (a)      Each of the following acts or occurrences constitutes a
"Servicer Default" under the Servicing Agreement with respect to the 2003-A
SUBIs:

                  (i)      the Servicer fails to deliver, or cause to be
         delivered, any required payment to the Indenture Trustee for
         distribution to the Noteholders or to the Owner Trustee for
         distribution to the Trust Certificateholders, or fails to deliver to
         the Trustee (acting through the Trust Agent) for distribution to the
         Indenture Trustee and the Owner Trustee any required payment, which
         failure continues for five Business Days after discovery of such
         failure by an officer of the Servicer or receipt by the Servicer of
         notice thereof from the Indenture Trustee, the Owner Trustee, or
         holders of Notes or Trust Certificates evidencing not less than 25% of
         the aggregate unpaid principal balance of the Securities (which for
         this purpose includes Trust Certificates held by the Trust, the
         Transferor, the Servicer (so long as NMAC or an Affiliate is the
         Servicer) and their respective Affiliates), voting together as a single
         class;

                  (ii)     the Servicer fails to deposit, apply, or distribute
         any amounts in the manner and at such time as required pursuant to the
         Servicing Agreement, including a

         failure to deliver to the Trustee for distribution to or for the
         account of a Holder of the 2003-A SUBI Certificate, any amounts
         required to be so distributed pursuant to the Servicing Agreement, and
         such failure shall have continued for a period of ten Business Days
         after either discovery of such failure by an officer of the Servicer or
         written notice of such failure shall have been given to the Servicer by
         the Trustee or such Holder;

                  (iii)    the Servicer fails to duly observe or perform in any
         material respect any of its covenants or agreements in the Servicing
         Agreement not otherwise covered in this Section 8.12(a), which failure
         materially and adversely affects the rights of the Titling Trust or a
         Holder of the 2003-A SUBI Certificate or the holders of the Notes, or
         Trust Certificateholders, and which continues unremedied for 90 days
         after receipt by the Servicer of written notice thereof from the
         Trustee or the related Holder or such default becomes known to the
         Servicer;

                  (iv)     the Servicer fails to deliver to the Trustee any
         report required to be delivered to the Trustee pursuant to the
         Servicing Agreement, which failure continues for 30 Business Days after
         discovery of such failure by an officer of the Servicer or receipt by
         the Servicer of written notice thereof by the Trustee;

                  (v)      the Servicer fails to deliver to the Indenture
         Trustee any report required to be delivered to the Indenture Trustee or
         the Trust pursuant to the Basic Documents to which the Servicer is a
         party, which failure continues for 30 Business Days after discovery of
         such failure by an officer of the Servicer or receipt by the Servicer
         of written notice thereof by the Indenture Trustee;

                  (vi)     any representation, warranty, or statement of the
         Servicer made in the Servicing Agreement, any other Basic Document to
         which the Servicer is a party or by which it is bound or any
         certificate, report or other writing delivered pursuant to the
         Servicing Agreement that proves to be incorrect in any material respect
         when made, which failure materially and adversely affects the rights of
         a Holder of the 2003-A SUBI Certificate or the holders of the Notes, or
         the Trust Certificateholders, and, if such default is of a type that
         may be corrected, the failure continues unremedied for 30 days after
         receipt by the Servicer of written notice thereof from the Trustee or
         the related Holder, or such default becomes known to the Servicer;

                  (vii)    the Servicer fails to maintain, or cause to be
         maintained, or pay when due, or cause to be paid when due, the premium
         in respect of the Contingent and Excess Liability Insurance Policy,
         which failure continues for ten Business Days after discovery of such
         failure by an officer of the Servicer or receipt by the Servicer of
         written notice thereof by the Trustee or a Holder of the 2003-A SUBI
         Certificate; or

                  (viii)   (A) the existence of any Proceeding in, or the entry
         of a decree or order for relief by, a court or regulatory authority
         having jurisdiction over the Servicer in an involuntary case under the
         federal bankruptcy laws, as now or hereafter in effect, (B) the
         appointment of a receiver, liquidator, assignee, trustee, custodian,
         sequestrator, or other similar official with respect to the Servicer or
         of any substantial part of its property or

         Servicer, and in each case, the continuance of any such Proceeding
         unstayed and in effect for a period of 90 consecutive days, or
         immediately upon entry of any decree or order; or

                  (ix)     the Servicer (A) applies for or consents to the

         or (G) takes any corporate action for the purpose of effecting any of
         the foregoing;

provided, however, that notwithstanding any other provision of the Servicing
Agreement, (i) for the purpose of determining what constitutes a Servicer
Default with respect to the 2003-A SUBI, the provisions contained in this
Section 8.12(a) shall replace in their entirety the provisions contained in
Section 4.01(a) of the Basic Servicing Agreement and (ii) any Servicer Default
with respect to the 2003-A SUBI shall not constitute a Servicing Default with
respect to any other Sub-Trust and any Servicing Default (as such term is
defined in the Basic Servicing Agreement) with respect to any other Sub-Trust
shall constitute a Servicer Default (as such term is defined in the Basic
Servicing Agreement) only with respect to such Sub-Trust and not with respect to
the 2003-A SUBI.

         Notwithstanding the foregoing, a delay in or failure of performance
under (a) clauses (i) and (ii) for a period of ten Business Days, (b) clause
(iii) for a period of 120 days, (c) clauses (iv) and (v) for a period of 60
days, or (d) clause (vi) for a period of 90 days shall not constitute a Servicer
Default if caused by a Force Majeure Event. Upon the occurrence of any Force
Majeure Event, the Servicer will not be relieved from using all commercially
reasonable efforts to perform its obligations in a timely manner in accordance
with the terms of the Servicing Agreement, and the Servicer must provide to the
Trustee, the Indenture Trustee, the Owner Trustee and the Transferor prompt
notice of such failure or delay by it, together with a description of its
efforts to so perform its obligations.

         (b)      Upon the occurrence of any Servicer Default, the Servicer, in
addition to complying with the notice requirements of Section 4.01(b) of the
Basic Servicing Agreement (except that references therein to Registered Pledgees
shall mean each Registered Pledgee of the 2003-A SUBI Certificate), shall
provide to the Indenture Trustee and the Owner Trustee prompt notice of any (i)
Servicer Default or (ii) event or condition that, with the giving of notice or
the passage of time, or both, would become a Servicer Default, accompanied in
each case by a description of the nature of the default and the Servicer's
efforts to remedy the same.

         (c)      In addition to the provisions of Section 4.01(c) of the Basic
Servicing Agreement, if a Servicer Default shall have occurred and is continuing
with respect to the 2003-A SUBI, the Trustee, on behalf of the Titling Trust,
shall, at the direction of the Required Related Holders, by notice given to the
Servicer, each Rating Agency, the Related Beneficiary and the holders of the
Rated Securities, terminate the rights and obligations of the Servicer under
this 2003-A Servicing

Supplement in accordance with such Section. In the event that the Servicer is
removed as servicer with respect to servicing the 2003-A SUBI Assets, subject to
the consent of the Trustee, the Required Related Holders shall appoint a
successor Servicer. The successor Servicer shall accept its appointment by a
written assumption in a form acceptable to the Trustee. Such successor Servicer
shall be approved by the Trustee, such approval not to be unreasonably withheld.
Notwithstanding the provisions of Section 4.01(e) of the Basic Trust Agreement,
with respect to any Servicer Default related to the 2003-A SUBI Assets, the
Trustee, acting on the direction of the Required Related Holders, may waive any
default of the Servicer in the performance of its obligations under the
Servicing Agreement and its consequences with respect to the 2003-A SUBI and,
upon any such waiver, such default shall cease to exist and any Servicer Default
arising therefrom shall be deemed to have been remedied for every purpose of the
Servicing Agreement. No such waiver shall extend to any subsequent or other
default or impair any right consequent thereto. For purposes of this Section, so
long as the Lien of the Indenture is in place, the Required Related Holders
shall be deemed to be the Indenture Trustee (as Registered Pledgee of the 2003-A
SUBI Certificates), acting at the direction of the Required Percentage of the
Noteholders and thereafter, the Owner Trustee, acting at the direction of the
Required Percentage of the Trust Certificateholders (which for this purpose
shall include Trust Certificates owned by the Trust, the Transferor, the
Servicer (so long as NMAC or an Affiliate is the Servicer) and any of their
respective Affiliates) until the Aggregate Certificate Balance has been reduced
to zero.

         (d)      If the Servicer is removed with respect to servicing the
2003-A SUBI Assets, the Servicer shall be entitled to reimbursement for any
outstanding Advances made pursuant to this 2003-A Servicing Supplement, to the
extent of the funds available therefor with respect to all Advances made by the
Servicer.

         Section 8.13. Servicer Representations and Warranties. Effective as of
the date hereof, the Servicer hereby reaffirms the representations and
warranties set forth in Section 2.06(a) and Section 5.01 of the Basic Servicing
Agreement, except that references to "this Agreement" shall be deemed to refer
to the Servicing Agreement, as such term is defined herein.

         Section 9.01. Termination of Servicing Supplement. This 2003-A

termination of the 2003-A SUBI or (ii) the resignation or removal of the
Servicer with respect to the 2003-A SUBI in accordance with the terms of the
Servicing Agreement. Any such termination hereunder shall effect a termination
only with respect to the 2003-A SUBI Assets and not as to Trust Assets allocated
to any other Sub-Trust, and shall not effect a termination of the Basic
Servicing Agreement or any other supplement to the Basic Servicing Agreement.

         Section 9.02. Governing Law. This 2003-A Servicing Supplement shall be
governed by and construed in accordance with the internal laws of the State of

         Section 9.03. Amendment. Notwithstanding the foregoing, this 2003-A
Servicing Supplement (and, accordingly, the Basic Servicing Agreement, insofar
as it relates to the 2003-A SUBI) may be amended by the parties hereto:

         (a)      without the consent of the Holders, to cure any ambiguity,
correct or supplement any provision herein that may be inconsistent with any
other provision herein, add any other provision with respect to matters or
questions arising hereunder that is not inconsistent with the Basic Servicing
Agreement or 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

         (b)      from time to time (including to change the remittance schedule
for depositing SUBI Collections and other amounts into the 2003-A SUBI
Collection Account, or to change the manner in which the Reserve Account is
funded), provided that (A) each Rating Agency has received prior written
notification from the Owner Trustee 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
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 2003-A SUBI Certificate or the 2003-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 a 2003-A SUBI or the 2003-A SUBI
Certificate or distributions (or the interest thereon) required to be made on
any Notes, and the Trust Certificates or the Interest Rate of any Note or (B)
reduce the percentage of the aggregate principal amount of 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.

         Section 9.04. Relationship of this 2003-A Servicing Supplement to Other
Trust Documents. Unless the context otherwise requires, this 2003-A Servicing
Supplement and the other Trust Documents shall be interpreted so as to give full
effect to all provisions hereof and thereof. In the event of any actual conflict
between the provisions of this 2003-A Servicing Supplement and (i) the Titling
Trust Agreement, with respect to the servicing of any Trust Assets, the
provisions of this 2003-A Servicing Supplement shall prevail and (ii) the Basic
Servicing Agreement, the provisions of this 2003-A Servicing Supplement shall
control.

         Section 9.05. Binding Effect. The provisions of this 2003-A Servicing
Supplement shall be binding upon and inure to the benefit of the parties hereto
and their permitted successors and assigns, and all such provisions shall inure
