     WHEREAS, GMAC LLC, as successor to General Motors Acceptance Corporation
("GMAC"), as Initial Trust Beneficiary (the "Initial Trust Beneficiary"), the

     WHEREAS, pursuant to the VAULT Trust Agreement, the Trust has agreed to act
as nominee holder of legal title to certain vehicles purchased by GMAC, GMAC

designated from time to time pursuant to the VAULT Trust Agreement;

     WHEREAS, pursuant to the Transfer Direction, dated as of May [28], 2007
(the "COLT 2007-SN1 Transfer Direction"), by GMAC, in its capacity as Initial
Trust Beneficiary, and acknowledged, accepted and agreed to by the VAULT
Trustee, the Servicer and COLT, the Initial Trust Beneficiary directed the VAULT
Trustee to hold legal title to the portion of the Applicable Trust Estate of the

     WHEREAS, COLT and The Bank of New York Trust Company, N.A. (the "COLT

(the "COLT Indenture"), pursuant to which COLT issued the COLT 2007-SN1 Secured

the Vehicles related to the Series 2007-SN1 Lease Assets to the Pledgees in
order to secure COLT's obligations under the COLT 2007-SN1 Secured Notes;

     NOW, THEREFORE, for and in consideration of the premises, and for other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:



     SECTION 1. DEFINITIONS. Unless otherwise expressly provided in this
Agreement, all capitalized terms used herein shall, unless defined herein, have
the respective meanings set forth in the VAULT Trust Agreement; or if not
defined therein, in Part I of Exhibit I to the Declaration of Trust, dated as of
December 13, 2006 (as it may be amended from time to time, the "Declaration of
Trust") by Deutsche Bank Trust Company Delaware, as COLT Owner Trustee, and
acknowledged, accepted and agreed to by Central Originating Lease, LLC; or if
not defined therein, in Part I of Exhibit A to the COLT Servicing Agreement,
dated as of the date hereof (the "COLT Servicing Agreement"), between GMAC, as
Servicer, COLT and the COLT Indenture Trustee. The rules of construction set
forth in Part II of Exhibit A to the COLT Servicing Agreement shall apply
hereto.

     SECTION 2. GRANT OF SECURITY INTEREST. As security for the prompt payment
and performance of all Secured Obligations by COLT whether direct or indirect,
absolute or contingent, due or to become due, or now existing or hereafter
arising, the Pledgor hereby pledges, hypothecates, assigns, charges, mortgages,
delivers and transfers to the Pledgees, and grants to the Pledgees, a continuing
lien on and security interest in all of Pledgor's legal title to the Vehicles
related to the Series 2007-SN1 Lease Assets (the "Pledged Collateral"), whether
now existing or hereafter arising or acquired or substituted, for the equal and
ratable benefit of the Pledgees and their respective successors, transferees and
assigns. The Pledgees acknowledge that VAULT holds legal title to the Vehicles
related to the Series 2007-SN1 Lease Assets in trust for the benefit of COLT,
who enjoys all beneficial interest therein pursuant to the VAULT Trust Agreement
and that such beneficial interest is not included in the Pledged Collateral.

     SECTION 3. REPRESENTATIONS AND WARRANTIES. The Pledgor represents and
warrants that the Pledgor is a statutory trust, validly existing and in good
standing under the laws of the state of Delaware and all vehicles held by the
Pledgor are held in the name of VAULT and not in the name of the VAULT Trustee.
The Pledgor also represents and warrants that it has not granted or will not
grant a lien in the Pledged Collateral to any Person except the Pledge granted
hereunder.

     SECTION 4. CONTINUING PLEDGE. This Agreement shall create a continuing
security interest in the Pledged Collateral and shall (a) remain in full force
and effect until the payment in full of all Secured Obligations, (b) be binding
upon the Pledgor and its successors, transferees and assigns, and (c) inure,
together with the rights and remedies of the Pledgees, to the equal and ratable
benefit of the Pledgees and their respective successors, transferees and
assigns.

     SECTION 5. RELEASE OF SECURITY INTEREST. The Pledgees hereby acknowledge
and agree that, if in accordance with Sections 2.04, 2.06 or 2.13 of the COLT
Servicing Agreement or Section 4.04 of the COLT Sale and Contribution Agreement,
COLT sells or reconveys any Vehicle related to a Series 2007-SN1 Lease Asset,
the Pledgees' security interest in legal title to the Vehicles that are sold or
reconveyed by COLT will be released automatically upon such sale or
reconveyance, and, in the case of the sale of a Vehicle pursuant to Sections
2.04 or 2.06 of the COLT Servicing Agreement, the Servicer shall instruct the
Trust to convey legal title to the Vehicle to the purchaser of such Vehicle.

     SECTION 6. REINSTATEMENT, ETC. If at any time any payment (in whole or in
part) of any of the Secured Obligations is rescinded or must otherwise be
restored by the Pledgees, due to


                                        2



the insolvency, bankruptcy or reorganization of COLT or otherwise, such Secured
Obligations shall, for the purposes of this Agreement, to the extent that such
payment is or must be rescinded or returned, be deemed to have continued in
existence, notwithstanding such application of payment, and this Agreement shall
continue to be effective or be reinstated, as the case may be, as to such
Secured Obligations all as though such application of payment had not been made.

     SECTION 7. WAIVER, ETC. The Pledgor hereby waives promptness, diligence,
notice of acceptance and any other notice with respect to any of the Secured
Obligations and this Agreement and any requirement that the Pledgees protect,
secure, perfect or insure any security interest or lien, or any property subject
thereto, or exhaust any right or take any action against any other Person or
entity or any collateral securing any Secured Obligations.

     SECTION 8. REMEDIES. The Pledgees may exercise all rights and remedies of a
secured party following the occurrence of and during the continuation of any
Event of Default under the COLT Indenture under the Uniform Commercial Code as
in effect in the State of New York in accordance with and pursuant to the COLT
Indenture.

     SECTION 9. NONENCUMBRANCE. The undersigned will not and COLT has not
directed and will not direct VAULT to sell, assign, transfer, pledge or encumber
in any other manner the Pledged Collateral (except as in favor of the Pledgees
hereunder), except the rights of COLT as Applicable Trust Beneficiary in such
Vehicles related to the Series 2007-SN1 Lease Assets granted under the VAULT
Trust Agreement, which rights are not included in the Pledged Collateral.

     SECTION 10. COLT 2007-SN1 BASIC DOCUMENTS. This Agreement is executed in
connection with the COLT 2007-SN1 Basic Documents and shall be construed,
administered and applied in accordance with the terms and provisions thereof.

     SECTION 11. ADDITIONAL TERMS. In addition to the agreements set forth in
Section 5, the Pledgees hereby agree to release (or cause to be released) all of
their respective interests in the Pledged Collateral upon the occurrence of the
full and complete satisfaction of the Secured Obligations and upon satisfaction
and discharge of the COLT Indenture pursuant to Section 4.1 of the COLT
Indenture, which release shall be automatic upon such full and complete
satisfaction of the Secured Obligations.
