                             REIMBURSEMENT AGREEMENT

         REIMBURSEMENT AGREEMENT (this "Reimbursement Agreement"), dated as of
September 25, 2003, among GENERAL ELECTRIC CAPITAL SERVICES, INC. ("GECS"), and
DEUTSCHE BANK AG, NEW YORK BRANCH (the "Counterparty").

                                    RECITALS

         WHEREAS, the Counterparty has entered into a ISDA Master Agreement,
dated as of September 25, 2003 (such agreement, as amended, supplemented or
modified from time to time, the "Agreement"), with GE Commercial Equipment
Financing, L.L.C., Series 2003-1 (the "Issuer") providing, among other things,
for Issuer to make certain payments to Counterparty in connection with an
interest rate swap transaction (the "Transaction") evidenced by the Agreement
and by a Confirmation dated as of September 25, 2003, with Transaction Reference
Number N258043N (the "Confirmation") made under the Agreement; capitalized terms
used and not otherwise defined herein are used as defined (directly or by
reference) in the Confirmation;

         WHEREAS, GECS is willing to enter into this Reimbursement Agreement to
induce the Counterparty to enter into the Confirmation with Issuer;

         NOW, THEREFORE, GECS and the Counterparty hereby agree:

         SECTION 1. FAST-PAY AND SLOW-PAY ADJUSTMENTS. GECS and the Counterparty
agree as follows:

                  (a)      Not less than two Business Days prior to each Payment
         Date or Early Termination Date under the Confirmation, GECS shall
         determine and notify the Calculation Agent of (i) the Notional Amount
         for purposes of determining the amounts payable under the Confirmation
         on such Payment Date or Early Termination Date and whether such
         Notional Amount is (A) less than the amount (the "Scheduled Notional
         Amount") shown in the "Average Balance" column on Exhibit A for the
         month immediately prior to the month in which such date occurs (in
         which case the absolute value of the difference is referred to as a
         "Fast-Pay Amount"), (B) equal to the Scheduled Notional Amount for such
         immediately prior Settlement Period (in which case there shall be no
         Fast-Pay Amount or Slow-Pay Amount for such Payment Date) or (C)
         greater than the Scheduled Notional Amount for such immediately prior
         Settlement Period (in which case the absolute value of the difference
         is referred to as a "Slow-Pay Amount"). GECS will provide to the
         Calculation Agent upon request any calculation requested by the
         Calculation Agent.

                  (b)      On any Payment Date or Early Termination Date with
         respect to which there exists any Fast-Pay Amount or Slow-Pay Amount,
         the Calculation Agent shall notify GECS of the amount (the "Fast-Pay
         Adjustment Amount" or "Slow-Pay Adjustment Amount", respectively) which
         would be payable (and by which party) under the Confirmation on such
         Payment Date or Early Termination Date if the Notional Amount used to
         determine payments due on such Payment Date or Early Termination

<PAGE>

         Date were equal to the Fast-Pay Amount or Slow-Pay Amount, as
         applicable, and all other terms of the Confirmation remained unchanged.

                  (c)      On each Payment Date or Early Termination Date as to
         which there was a Fast-Pay Amount or Slow-Pay Amount, the parties
         hereto shall make the following payments, as applicable:

                           (i)      if there was a Fast-Pay Amount with respect
                  to such Payment Date or Early Termination Date, and the actual
                  net payment due under the Confirmation on such Payment Date or
                  Early Termination Date was owed by Issuer, then GECS shall pay
                  to the Counterparty an amount equal to the applicable Fast-Pay
                  Adjustment Amount;

                           (ii)     if there was a Fast-Pay Amount with respect
                  to such Payment Date or Early Termination Date, and the actual
                  net payment due under the Confirmation on such Payment Date or
                  Early Termination Date was owed by the Counterparty, then the
                  Counterparty shall pay to GECS an amount equal to the
                  applicable Fast-Pay Adjustment Amount;

                           (iii)    if there was a Slow-Pay Amount with respect
                  to such Payment Date or Early Termination Date, and the actual
                  net payment due under the Confirmation on such Payment Date or
                  Early Termination Date was owed by the Counterparty, then GECS
                  shall pay to the Counterparty an amount equal to the
                  applicable Slow-Pay Adjustment Amount; and

                           (iv)     if there was a Slow-Pay Amount with respect
                  to such Payment Date or Early Termination Date, and the actual
                  net payment due under the Confirmation on such Payment Date or
                  Early Termination Date was owed by Issuer, then the
                  Counterparty shall pay to GECS an amount equal to the
                  applicable Slow-Pay Adjustment Amount.

         SECTION 2. Payment Upon Early Termination. GECS and the Counterparty
agree as follows:

                  (a)      In the event of a designation of an Early Termination
         Date as provided for in the Agreement, simultaneously with the
         calculations of amounts owed thereto, GECS shall notify the Calculation
         Agent of (i) any Fast Pay Amount or Slow Pay Amount (calculated in
         accordance with the methodology set forth in Section 1) and (ii) the
         net amount owed (and by which party) pursuant to subsection (i) above.

                  (b)      On the date determined in accordance with the
         Agreement in the event of an Early Termination Date, GECS and the
         Counterparty shall make the following payments:

                           (i)      In the event that the net amount calculated
                  pursuant to clause (a) above is owed by the Counterparty to
                  GECS, then the Counterparty shall promptly pay such amount to
                  GECS in accordance with this Reimbursement Agreement.

<PAGE>

                           (ii)     In the event that the net amount calculated
                  pursuant to clause (a) above is owed by GECS to the
                  Counterparty, then the GECS, shall promptly pay such amount to
                  the Counterparty in accordance with this Reimbursement
                  Agreement.

         SECTION 3. MISCELLANEOUS.

3.1 NOTICES. All notices to GECS under this Reimbursement Agreement and copies
of all notices of payment failure or other breaches by Issuer of the
Confirmation sent to Issuer under the Agreement shall, until GECS furnishes
written notice to the contrary, be mailed or delivered to GECS at 3001 Summer
Street, 2nd Floor, Stamford, Connecticut 06927, and directed to the attention of
the Portfolio Manager.

3.2 GOVERNING LAW. This Reimbursement Agreement shall be construed and enforced
in accordance with, and governed by, the laws of the State of New York, United
States of America.

3.3 CONSENT TO JURISDICTION. EACH PARTY HERETO HEREBY CONSENTS AND AGREES THAT
THE STATE OR FEDERAL COURTS LOCATED IN THE BOROUGH OF MANHATTAN IN NEW YORK CITY
SHALL HAVE EXCLUSIVE JURISDICTION TO HEAR AND DETERMINE ANY CLAIMS OR DISPUTES
BETWEEN THEM PERTAINING TO THIS AGREEMENT OR TO ANY MATTER ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR ANY RELATED DOCUMENT; PROVIDED, THAT EACH PARTY
HERETO ACKNOWLEDGES THAT ANY APPEALS FROM THOSE COURTS MAY HAVE TO BE HEARD BY A
COURT LOCATED OUTSIDE OF THE BOROUGH OF MANHATTAN IN NEW YORK CITY. EACH PARTY
HERETO SUBMITS AND CONSENTS IN ADVANCE TO SUCH JURISDICTION IN ANY ACTION OR
SUIT COMMENCED IN ANY SUCH COURT, AND EACH PARTY HERETO HEREBY WAIVES ANY
OBJECTION THAT SUCH PARTY MAY HAVE BASED UPON LACK OF PERSONAL JURISDICTION,
IMPROPER VENUE OR FORUM NON CONVENIENS.

3.4 WAIVER OF JURY TRIAL. BECAUSE DISPUTES ARISING IN CONNECTION WITH COMPLEX
FINANCIAL TRANSACTIONS ARE MOST QUICKLY AND ECONOMICALLY RESOLVED BY AN
EXPERIENCED AND EXPERT PERSON AND THE PARTIES WISH APPLICABLE STATE AND FEDERAL
LAWS TO APPLY (RATHER THAN ARBITRATION RULES), THE PARTIES DESIRE THAT THEIR
DISPUTES BE RESOLVED BY A JUDGE APPLYING SUCH APPLICABLE LAWS. THEREFORE, TO
ACHIEVE THE BEST COMBINATION OF THE BENEFITS OF THE JUDICIAL SYSTEM AND OF
ARBITRATION, THE PARTIES HERETO WAIVE ALL RIGHT TO TRIAL BY JURY IN ANY ACTION,
SUIT, OR PROCEEDING BROUGHT TO RESOLVE ANY DISPUTE, WHETHER SOUNDING IN
CONTRACT, TORT OR OTHERWISE, ARISING OUT OF, CONNECTED WITH, RELATED TO, OR
INCIDENTAL TO THE RELATIONSHIP ESTABLISHED AMONG THEM IN CONNECTION WITH THIS
AGREEMENT OR ANY RELATED DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR
THEREBY.

3.5 INTERPRETATION. The headings of the sections and other subdivisions of this
Reimbursement Agreement are inserted for convenience only and shall not be
deemed to constitute a part hereof.

3.6 ATTORNEY'S COST. Each party agrees to pay all reasonable attorney's fees and
disbursements and all other reasonable and actual costs and expenses which may
be incurred by the other party in the enforcement of this Reimbursement
Agreement.

3.7 NO SET-OFF. The Counterparty hereby waives any right to set-off, combine,
consolidate, or otherwise appropriate and apply, any indebtedness at any time
held or owing by the Counterparty under any agreements other than this
Reimbursement Agreement against, or on account of, any obligations or
liabilities of GECS under this Reimbursement Agreement; provided, however, that
nothing contained in this Section 3.7 shall constitute the waiver by any party
of any right to set-off, combine, consolidate or otherwise appropriate and apply
any indebtedness at any time held or owing by such party against, or on account
of, any obligations or liabilities of the other party that such party may have
by operation of law.

3.8 CURRENCY OF PAYMENT. Any payment to be made by GECS or Counterparty pursuant
to this Reimbursement Agreement shall be made in the same currency as designated
for payment in the Confirmation and such designation of the currency of payment
is of the essence.

3.9 TRANSFER. Neither this Reimbursement Agreement nor any interest or
obligation in or under this Reimbursement Agreement may be transferred (whether
by way of security or otherwise) by any party hereto without the prior written
consent of the other parties hereto, except that the Counterparty or Issuer may,
without the consent of the other parties hereto, transfer its interest in this
Reimbursement Agreement to any person or entity to which any interest or
obligation in or under the Confirmation is transferred in a manner that is not
inconsistent with the Agreement. GECS's obligations under this Reimbursement
Agreement shall continue notwithstanding any transfer by Issuer in accordance
with the Agreement of its rights and/or obligations under the Confirmation or
the Agreement as it relates to the Transaction, and the term "Issuer" as used
herein shall be deemed to refer to any transferee of Issuer's rights and/or
obligations under the Confirmation or the Agreement as it relates to the
Transaction.

3.10 NETTING. Notwithstanding any provision herein to the contrary, all amounts
payable on the same date by (or to) GECS to (or from) the Counterparty hereunder
or under Other Reimbursement Agreements (as defined below) shall be netted such
that each such party's obligation to make payment on any such date will be
automatically satisfied and discharged and (if the aggregate amount that would
otherwise have been payable by GECS or the Counterparty exceeds the aggregate
amount that otherwise have been payable by the Counterparty or GECS,
respectively) replaced by an obligation upon the party by whom the larger
aggregate amount would have been payable to pay to such other party the excess
of the larger aggregate amount over the smaller aggregate amount. "Other
Reimbursement Agreements" means the two other Reimbursement Agreements, dated as
of the date here of, between GECS and the Counterparty which relate to
Transactions with Transaction Reference Numbers N258123N and N258197N.

3.11 AUTHORITY. Both parties represent that:

         reorganization, moratorium and other laws of general applicability
         relating to or affecting creditors rights and to general equity
         principals.

modification and waiver in respect of it) may be executed and delivered in

NON-PETITION. Counterparty and GECS each hereby covenant and agree that, prior
to the date which is one year and one day after the payment in full by Issuer of
the Class A Notes and the Class B Notes, it will not institute against Issuer
any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceedings or other similar proceeding under the laws of the United States or

rights against GECS, or GECS rights against Counterparty, for claims arising
under this Reimbursement Agreement.
