                        COLT 2007-SN1 SERVICING AGREEMENT

     THIS COLT 2007-SN1 SERVICING AGREEMENT, dated as of June 7, 2007 (this
"COLT Servicing Agreement" or this "Agreement"), is between CENTRAL ORIGINATING
LEASE TRUST, a Delaware statutory trust ("COLT"), GMAC LLC, a Delaware limited
liability company ("GMAC"), as servicer (the "Servicer"), and THE BANK OF NEW
YORK TRUST COMPANY, N.A., national banking association organized under the laws
of the United States of America, as COLT Indenture Trustee (the "COLT Indenture
Trustee").

     WHEREAS, Deutsche Bank Trust Company Delaware, as COLT Owner Trustee (the
"COLT Owner Trustee") has entered into the Declaration of Trust, dated as of
December 13, 2006, acknowledged, accepted and agreed by Central Originating
Lease, LLC, a Delaware limited liability company ("COLT, LLC"), as Residual
Certificateholder (as amended, modified or otherwise supplemented from to time,
the "Declaration of Trust");

     WHEREAS, the COLT Owner Trustee and COLT, LLC, as the Residual
Certificateholder, are entering into a COLT 2007-SN1 Supplement to the
Declaration of Trust, dated as of the date hereof, to segregate the Series
2007-SN1 Lease Assets into a separate Series under the Declaration of Trust;

     WHEREAS, COLT and the COLT Indenture Trustee are entering into the COLT
Indenture, dated as of the date hereof, to provide for the issuance of the COLT
2007-SN1 Secured Notes;

     WHEREAS, the parties desire to enter into this Agreement to provide for,
among other things, the servicing of Series 2007-SN1 Lease Assets by the
Servicer;

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
herein contained, the parties hereto agree as follows:

                                    ARTICLE I
                                   DEFINITIONS

     SECTION 1.01 Definitions. Capitalized terms used in this Agreement are
defined in and shall have the meanings assigned to them in the COLT Series
Definitions attached as Exhibit A, or if not defined therein, shall have the
meanings assigned to them in the COLT Program Definitions attached as Exhibit I

this COLT Servicing Agreement as it may be amended, supplemented or otherwise
modified from time to time.

                                   ARTICLE II
                  ADMINISTRATION AND SERVICING OF LEASE ASSETS

     SECTION 2.01 Duties of the Servicer.

     (a) The Servicer is hereby authorized to act as agent for COLT and in such
capacity shall manage, service, administer and make collections on and
dispositions of the Series 2007-SN1 Lease Assets in accordance with this
Agreement with reasonable care, using that degree of



skill and attention that the Servicer exercises with respect to comparable
automotive leases that it services for itself or others. Each of the COLT
2007-SN1 Secured Noteholders and the COLT 2007-SN1 Certificateholder, by
acceptance of a COLT 2007-SN1 Secured Note or the COLT 2007-SN1 Certificate, as
the case may be, authorizes the Servicer to service, administer and make
payments on its COLT 2007-SN1 Secured Note or its COLT 2007-SN1 Certificate as
provided herein. The Servicer hereby accepts such appointment and authorization
and agrees to perform the duties of Servicer set forth herein and in any other
COLT 2007-SN1 Basic Document to which the Servicer is a party with respect to
the Series 2007-SN1 Lease Assets, the COLT 2007-SN1 Secured Notes and the COLT
2007-SN1 Certificates.

     (b) The Servicer's duties shall include collecting and posting of all
payments, responding to inquiries of Lessees, remarketing returned Vehicles,
investigating delinquencies, sending billing statements or coupon books to
Lessees, reporting required tax information (if any) to Lessees, policing the
Vehicles, monitoring the status of insurance policies with respect to the
Lessees and the Vehicles, accounting for collections and furnishing monthly and
annual statements to COLT with respect to distributions, generating federal
income tax information, giving, on a timely basis, any required notices or
instructions to the COLT Owner Trustee under the Declaration of Trust, giving
any required instructions to VAULT under the VAULT Trust Agreement and
performing the other duties specified herein or in any other COLT 2007-SN1 Basic
Document. Subject to the provisions of this Agreement, the Servicer shall follow
its Customary Servicing Practices and shall have full power and authority,
acting alone, to do any and all things in connection with such managing,
servicing, administering and collecting that it may deem necessary or desirable.

     (c) Without limiting the generality of the foregoing, the Servicer is
hereby designated by COLT as the true and lawful attorney and agent for and on
behalf of COLT, with full power and authority to perform any and all acts
related to managing, servicing, administering and collecting any part of the
COLT 2007-SN1 Trust Estate and any and all acts otherwise required or permitted
to be performed by the Servicer under this Agreement and the other COLT 2007-SN1
Basic Documents and is hereby authorized and empowered by COLT to execute and
deliver, in its own name or on behalf of COLT, or both of them, as the case may
be, any and all instruments of satisfaction, extension or cancellation, or of
partial release or discharge, and all other comparable instruments, with respect
to Series 2007-SN1 Lease Assets. The Servicer also has the right, power and
authority to designate in writing other Persons as true and lawful attorneys and
agents for and on behalf of COLT to do anything that the Servicer has the power
to do under this Agreement or the other COLT 2007-SN1 Basic Documents; provided,
however, that notwithstanding any such designation, the Servicer shall remain
liable for the performance of the duties and obligations of the Servicer
hereunder and thereunder.

     (d) In addition, the Servicer shall have the full power and authority to do
or cause to be done any and all things in connection with the servicing and
administration of the Series 2007-SN1 Lease Assets that the Servicer may deem
necessary or desirable in connection with arranging for the sale or other
liquidation of the Vehicles upon its receipt of possession thereof. In
connection with any such sale or other liquidation of any such Vehicle, other
than any sale directly or indirectly of such Vehicle to the related Lessee in
accordance with the related Series 2007-SN1 Lease, the Servicer shall use
commercially reasonable efforts to maximize the Sale Proceeds received in
connection with the sale or other liquidation of any such Vehicle; provided,

                                                             Servicing Agreement
                                                                 (COLT 2007-SN1)



however, that the Servicer shall have no liability to COLT or the Series
2007-SN1 Further Holders in connection with any sale or other liquidation of a
Vehicle related to a Series 2007-SN1 Lease Asset to the extent the Servicer
arranges for such sale or other liquidation of such Vehicle in accordance with
its Customary Servicing Practices.

     (e) The Servicer is hereby authorized to commence, in its own name or in
the name of COLT, a legal proceeding to enforce a defaulted Series 2007-SN1
Lease Asset as contemplated by Section 2.05, to enforce all obligations of COLT
under this Agreement and the other COLT 2007-SN1 Basic Documents or to commence
or participate in a legal proceeding (including a bankruptcy proceeding)
relating to or involving a Series 2007-SN1 Lease Asset. If the Servicer
commences or participates in such a legal proceeding in its own name, COLT shall
thereupon be deemed to have automatically assigned such Series 2007-SN1 Lease
Asset to the Servicer for purposes of commencing or participating in any such
proceeding as a party or claimant, and the Servicer is hereby authorized and
empowered by COLT to execute and deliver in the Servicer's name any notices,
demands, claims, complaints, responses, affidavits or other documents or
instruments in connection with any such proceeding. COLT shall furnish the
Servicer with any powers of attorney and other documents and take any other
steps which the Servicer may deem necessary or appropriate to enable the
Servicer to carry out its servicing and administrative duties under this
Agreement and the other COLT 2007-SN1 Basic Documents. If in any enforcement
suit or legal proceeding it is held that the Servicer may not enforce a Series
2007-SN1 Lease Asset on the grounds that it is not a real party in interest or a
holder entitled to enforce such Series 2007-SN1 Lease Asset, the COLT Owner
Trustee shall, at the Servicer's expense, take such steps as the Servicer deems
necessary to enforce such Series 2007-SN1 Lease Asset, including bringing such
suit or proceeding in the COLT Owner Trustee's name.

     SECTION 2.02 Collection of Series 2007-SN1 Lease Payments and Pull Ahead
Payments.

     (a) The Servicer shall make commercially reasonable efforts to collect all
payments called for under the terms and provisions of the Series 2007-SN1 Leases
as and when the same shall become due in accordance with the Servicer's
Customary Servicing Practices; provided, however, that any waiver, extension or
modification of the terms of any Series 2007-SN1 Lease shall be granted by the
Servicer solely (i) pursuant to a Pull Ahead Program in accordance and upon full
compliance with the COLT Pull Ahead Funding Agreement, which shall be
substantially in the form attached as Exhibit C hereto, or (ii) in accordance
with Section 2.11; and provided, further, that the Servicer shall have no
obligation to collect any payments required under any Administrative Lease Asset
or Warranty Lease Asset following COLT's receipt of the related Administrative
Purchase Payment or Warranty Payment, as applicable.

     (b) If GMAC, in its capacity as agent for General Motors, or General Motors
institutes a Pull Ahead Program, the Servicer shall permit a Lessee under a
Series 2007-SN1 Lease Asset to participate in such Pull Ahead Program, and the
Servicer shall modify such Series 2007-SN1 Lease by accepting the Pull Ahead
Payment from GMAC in lieu of receiving all or a portion of the remaining Monthly
Lease Payments from the related Lessee, if, (but only if) the conditions to
participation specified in the proviso to the first sentence of Section 2.01 of
the COLT Pull Ahead Funding Agreement have been satisfied. On the first business
day of each Collection Period, the Servicer (if the Servicer is not GMAC) shall
notify the Pull Ahead Agent



of the identity of all Series 2007-SN1 Lease Assets that have become Pull Ahead
Lease Assets during the immediately preceding Collection Period and the total
amount of Pull Ahead Payments paid and remaining to be paid with respect to each
such Pull Ahead Lease Asset. If GMAC, as agent for General Motors, does not
timely deposit all Pull Ahead Payments in the Collection Account, the Servicer
(including any successor servicer) shall use commercially reasonable efforts to
collect any such unpaid Pull Ahead Payments. Consistent with the foregoing, only
the Servicer (or any replacement servicer or delegate of the Servicer) shall be
entitled to modify the Series 2007-SN1 Lease related to any Pull Ahead Lease
Asset; provided, however, that any such modification shall be subject to and
consistent with the provisions of this Agreement. Consistent with the foregoing,
and notwithstanding anything to the contrary contained in this Agreement
(including Section 4.04) or any other COLT 2007-SN1 Basic Document, General
Motors shall have no right (and the Servicer shall not allow General Motors) to
waive, extend or modify any provision of any Series 2007-SN1 Lease whether in
connection with a Pull Ahead Program or otherwise. In connection with any Pull
Ahead Lease Asset, the Servicer shall charge the related Lessee any applicable
Excess Wear and Excess Mileage Charges in accordance with the related Series
2007-SN1 Lease and the Servicer's Customary Servicing Practices, and the
Servicer shall deposit any amounts received from the related Lessee on account
thereof into the COLT Collection Account in accordance with Section 3.04.

     (c) Upon the return of a Vehicle to a Dealer following the expiration or
termination of the related Series 2007-SN1 Lease, the Servicer shall cause the
Dealer or an independent third party to inspect such Vehicle to ascertain
whether Excess Wear and Excess Mileage Charges are due and whether there is a
need for any repairs, and shall cause the Dealer or an independent third party
to deliver a vehicle condition report to the Servicer. The Servicer shall
require the Lessee to pay the Excess Wear and Excess Mileage Charges for each
Vehicle in accordance with the terms of the applicable Series 2007-SN1 Lease.

     SECTION 2.03 Collection and Application of Security Deposits.

     (a) The Servicer shall separately account for any Security Deposit related
to the Series 2007-SN1 Lease Assets remitted to it or to COLT as agent and
bailee for COLT, and shall apply the proceeds of such Security Deposits in
accordance with applicable law, its Customary Servicing Practices and the Series
2007-SN1 Leases, including that the Servicer shall use the Security Deposit in
respect of any defaulted Series 2007-SN1 Lease for the payment of any amount
resulting from the related Lessee's default or failure to pay all amounts
required to be paid under such Series 2007-SN1 Lease and any Excess Wear and
Excess Mileage Charges.

     (b) In any Collection Period in which a Series 2007-SN1 Lease becomes a
Liquidating Lease Asset, the Servicer shall deposit into the COLT Collection
Account in accordance with Section 3.04, to the extent permitted by such Series
2007-SN1 Lease and applicable law, an amount equal to the lesser of (i) the
related Security Deposit and (ii) any amount to which the related Security
Deposit shall apply in accordance with such Series 2007-SN1 Lease and applicable
law, and such amount shall become part of the COLT Collections on such Series
2007-SN1 Lease Asset for such Collection Period. The remainder of the related
Security Deposit for any such Series 2007-SN1 Lease Asset, after the deposit of
the amounts, if any, referenced in the preceding sentence, shall be returned to
the related Lessee by the Servicer; provided, however, that the Servicer may
separately account for a Security Deposit (including



any interest therein) until the Lessee has repaid all other charges owed under
such Series 2007-SN1 Lease. As additional servicing compensation and as part of
its Supplemental Servicing Fee, the Servicer shall also be entitled to the
earnings from the investment of Security Deposits retained as and to the extent
permitted by applicable law and the applicable Series 2007-SN1 Lease and to the
extent not required to be paid to the Lessees.

     SECTION 2.04 Voluntary Early Terminations. If under any Series 2007-SN1
Lease the Lessee exercises its option to terminate such Series 2007-SN1 Lease
prior to its Scheduled Lease End Date, the Servicer shall, on behalf of COLT,
give instructions to VAULT to convey title to the related Vehicle to the Person
purchasing the related Vehicle. If neither the Lessee nor the Dealer purchases
the related Vehicle, the Servicer shall, as soon as reasonably practicable,
consign such Vehicle to a motor vehicle wholesale or retail dealer for resale,
sell such Vehicle at a private or public sale or take other commercially
reasonable actions in order to dispose of such Vehicle. In connection with the
sale of any Vehicle in accordance with this Section 2.04, the Servicer shall, on
behalf of COLT, give instructions to VAULT to convey title to such Vehicle to
the purchaser thereof.

     SECTION 2.05 Realization Upon Defaulted Series 2007-SN1 Lease Assets. The
Servicer shall use commercially reasonable efforts, consistent with its
Customary Servicing Practices, to repossess or otherwise comparably gain control
of any Vehicle that it has reasonably determined should be repossessed or
otherwise controlled following a default under the related Series 2007-SN1
Lease. The Servicer shall follow its Customary Servicing Practices, which
practices, policies and procedures may include, among other things, exercising
commercially reasonable efforts to realize upon any recourse to any Dealers,
consigning a Vehicle to a motor vehicle wholesale or retail dealer for resale,
selling such Vehicle at a public or private sale and taking other actions in
order to realize upon such Series 2007-SN1 Lease and/or Vehicle. The Servicer is
authorized to commence legal proceedings with respect to a Lease Asset in its
own name or in the name of COLT. In connection with the sale of any Vehicle in
accordance with this Section 2.05, the Servicer shall, on behalf of COLT, give
instructions to VAULT to convey title to such Vehicle to the purchaser thereof.
The Servicer is hereby authorized to exercise its discretion consistent with its
Customary Servicing Practices and the terms of the COLT 2007-SN1 Basic
Documents, in servicing the Liquidating Lease Assets so as to maximize the net
collection of those Liquidating Lease Assets, including the discretion to choose
to sell or not to sell any of the Liquidating Lease Assets on behalf of COLT.

     SECTION 2.06 Scheduled Expiration of Series 2007-SN1 Leases. At the
Scheduled Lease End Date for each Series 2007-SN1 Lease (or, with respect to any
Extended Lease, the date to which such Scheduled Lease End Date has been
extended), if the Lessee elects to exercise its option under such Lease to
purchase the related Vehicle, the Servicer shall determine whether the Dealer
that originated such Lease or COLT will sell the Vehicle to the Lessee. If the
Dealer is to sell the Vehicle to the Lessee, upon receipt of the purchase price
for such Vehicle from the Dealer and upon direction from the Dealer, the
Servicer shall, on behalf of COLT, give instructions to VAULT to convey title to
such Vehicle to the Lessee. If COLT is to sell the Vehicle to the Lessee, upon
receipt of the Lessee Purchase Amount, the Servicer shall, on behalf of COLT,
give instructions to VAULT to convey title to such Vehicle to the Lessee. If the
Lessee does not exercise its option to purchase the related Vehicle at the
Scheduled Lease End Date (or, with respect to any Extended Lease, the date to
which such Scheduled Lease End Date



has been extended), the Servicer shall determine if a Dealer will purchase such
Vehicle. If a Dealer elects to purchase the related Vehicle, upon receipt of the
purchase price for such Vehicle from the Dealer, the Servicer shall, on behalf
of COLT, give instructions to VAULT to convey title to such Vehicle to such
Dealer. If neither the Lessee nor a Dealer purchases the related Vehicle, the
Servicer shall, as soon as reasonably practicable, consign such Vehicle to a
wholesale or retail motor vehicle dealer for resale, sell such Vehicle at a
private or public sale or take other commercially reasonable actions in order to
dispose of such Vehicle. In connection with the sale of any Vehicle in
accordance with this Section 2.06, the Servicer shall, on behalf of COLT, give
instructions to VAULT to convey title to such Vehicle to the purchaser thereof.

     SECTION 2.07 Payment and Reimbursement of Liquidation Expenses.

     (a) In connection with the repossession or sale of any Vehicle, the
Servicer shall be entitled, if such Vehicle shall have sustained any damage, to
expend funds in connection with any repair or towards the repossession of such
Vehicle if it has determined in its discretion that such repair and/or
repossession shall increase the proceeds of liquidation of the Vehicle and
related Series 2007-SN1 Lease by an amount greater than the amount of such
expenses.

     (b) The Servicer shall be entitled to be reimbursed for the amount of any
Liquidation Expenses it has paid with respect to each Series 2007-SN1 Lease
Asset at such time as the related Vehicle has been sold or otherwise disposed of
by the Servicer in accordance with Section 3.03(b)(iii).

     SECTION 2.08 Maintenance of Insurance Policies.

     The Servicer shall, in accordance with its Customary Servicing Practices,
require that each Lessee shall have obtained all insurance required to be
obtained by the Lessee under the applicable Series 2007-SN1 Lease. The Servicer
shall, in accordance with its Customary Servicing Practices, monitor such
insurance with respect to such Series 2007-SN1 Lease. If a Lessee under any
Series 2007-SN1 Lease Asset fails to obtain or maintain any insurance required
under the related Series 2007-SN1 Lease, the Servicer shall act in accordance
with its Customary Servicing Practices.

     SECTION 2.09 Maintenance of Enforceable Ownership Interest, Beneficial
Ownership Interest and Security Interest in the Related Vehicles. The Servicer
shall, in accordance with its Customary Servicing Practices, take such steps as
are necessary to (a) establish and maintain the enforceable ownership interest
of VAULT in the Vehicles related to the Series 2007-SN1 Lease Assets in
accordance with the VAULT Trust Agreement, (b) establish and maintain COLT's
beneficial ownership interest in the Vehicles related to the Series 2007-SN1
Lease Assets in accordance with the VAULT Trust Agreement and (c) establish and
maintain the perfection of the COLT 2007-SN1 Secured Noteholders' security
interest in the Vehicles related to the Series 2007-SN1 Lease Assets. Each COLT
2007-SN1 Secured Noteholder hereby authorizes the Servicer to re-perfect such
security interest on its behalf as may be needed from time to time.

     SECTION 2.10 Custody of Lease Files. Simultaneously with the execution and
delivery of this Agreement, COLT shall enter into the COLT Custodian Agreement
with the COLT Custodian pursuant to which COLT shall revocably appoint the COLT
Custodian, and the



COLT Custodian shall accept such appointment, to act as the agent of COLT as
COLT Custodian of the following documents or instruments, which shall be
constructively delivered to COLT with respect to each Series 2007-SN1 Lease
Asset on behalf of the COLT 2007-SN1 Secured Noteholders:

     (a) the fully executed original of such Series 2007-SN1 Lease;

     (b) documents evidencing or related to any insurance policy covering the
related Vehicle;

     (c) the original application of each Lessee, fully executed by each Lessee
on a form that meets GMAC's customary origination standards;

     (d) where permitted by law, the original certificate of title (as soon as
it is received) and otherwise such documents, if any, that GMAC keeps on file in
accordance with its customary procedures indicating that title to the Vehicle is
in the name of VAULT and an interest as first lienholder or secured party is in
the name of GMAC; and

     (e) any and all other documents that GMAC keeps on file in accordance with
its customary procedures relating to any Series 2007-SN1 Lease, Lessee or
related Vehicle, including any written modifications or extensions.

     SECTION 2.11 Waivers, Modifications and Extensions on the Series 2007-SN1
Lease Assets.

     (a) The Servicer may, in its discretion and in accordance with its
Customary Servicing Practices: (i) waive any late payment charge or penalty
interest provision or any other provision of any Series 2007-SN1 Lease; (ii)
extend the term of any Series 2007-SN1 Lease and/or the due date for any payment
due from the Lessee thereunder; (iii) modify any provision of any Series
2007-SN1 Lease; (iv) accept extended performance under any Series 2007-SN1
Lease; and (v) take any other action to waive, extend or modify any of the
obligations of the Lessee under any Series 2007-SN1 Lease; provided, however,
that the Servicer shall not grant any such waiver, extension or modification or
take any other action if such waiver, extension, modification or other action
would (A) impair the enforceable ownership interest of VAULT, the beneficial
ownership interest of COLT, the Lien of the COLT 2007-SN1 Secured Noteholders in
the related Vehicle or the Lien of the COLT Indenture Trustee for the ratable
benefit of the COLT 2007-SN1 Secured Noteholders in such Series 2007-SN1 Lease,
(B) reduce the aggregate dollar amount of the Monthly Lease Payments due under
any Series 2007-SN1 Lease Asset, (C) extend the term of any Series 2007-SN1
Lease Asset beyond the last day of the sixth Collection Period immediately
preceding the Final Maturity Date of the related COLT 2007-SN1 Secured Note, or
(D) modify the amounts due from the Lessee upon the termination of any Series
2007-SN1 Lease, except that the Servicer may reduce the Lessee Purchase Amount
under any Series 2007-SN1 Lease Asset to the extent that the Servicer has
determined, in its discretion, that the reduction of such Lessee Purchase Amount
is reasonably likely to maximize the Sale Proceeds received by the Servicer in
connection with the sale or other liquidation of the related Vehicle; and
provided, further, that the foregoing provisions shall not prohibit the
Servicer's waiver of the



Lessee's payment of all or a portion of the remaining Monthly Lease Payments
with respect to any Pull Ahead Lease Asset pursuant to Section 2.02(b).

     (b) Notwithstanding any waiver, extension, modification or other action
taken by the Servicer with respect to a Series 2007-SN1 Lease in accordance with
Section 2.11(a), the Servicer may (but shall not be obligated to) make Monthly
Payment Advances and Residual Advances in accordance with Section 3.06 and shall
calculate the ABS Value of such Series 2007-SN1 Lease Asset as if such waiver,
extension, modification or other action had not occurred.

     SECTION 2.12 Covenants, Representations and Warranties of Servicer.

     (a) The Servicer covenants, with respect to each Series 2007-SN1 Lease
Asset, that from and after the Series 2007-SN1 Closing Date:

          (i) Legal Title to Vehicles. Except as otherwise expressly
contemplated by this Agreement and the VAULT Trust Agreement, the Servicer shall
maintain VAULT as the legal title holder of the related Vehicles;

          (ii) No Impairment. The Servicer shall do nothing to impair the rights
of COLT or the Series 2007-SN1 Further Holders in and to such Series 2007-SN1
Lease Assets and shall not create or permit to exist on any of the Series
2007-SN1 Lease Asset any Lien that arises from any act or omission of the
Servicer or with respect to which the Servicer has any payment liability;
provided, however, that the foregoing covenant shall not limit or impair the
Servicer's right to receive payments owing to it hereunder, including repayment
of Advances made pursuant to the terms hereof; and

          (iii) Payment of Sales and Use Tax Amounts and other State Tax
Covenants. The Servicer shall use commercially reasonable efforts to pay all
amounts it has received from the Lessee under such Series 2007-SN1 Lease Asset
with respect to Sales and Use Tax Amounts to the applicable taxing authorities
as the same shall become due and payable under applicable law. Upon having
actual knowledge of any Lien of any applicable State taxing authority upon such
Series 2007-SN1 Lease Asset, the Servicer shall use commercially reasonable
efforts to cause any such Series 2007-SN1 Lease Asset to be released from such
Lien.

     (b) The Servicer hereby represents and warrants as of the Series 2007-SN1
Closing Date:

          (i) Organization and Good Standing. The Servicer has been duly
organized and is validly existing as an entity in good standing under the laws
of the State of Delaware, with power and authority to own its properties and to
conduct its business as such properties are presently owned and such business is
presently conducted, and has the power, authority and legal right to service the
Series 2007-SN1 Lease Assets;

          (ii) Due Qualification. The Servicer is duly qualified to do business
as a foreign entity in good standing, and has obtained all necessary licenses
and approvals, in all jurisdictions in which the ownership or lease of property
or the conduct of its business (including



the servicing of the Series 2007-SN1 Lease Assets as required by this Agreement)
requires such qualification;

          (iii) Power and Authority. The Servicer has the power and authority to
execute and deliver this Agreement and each other COLT 2007-SN1 Basic Document
to which it is a party and to carry out its terms, and the execution, delivery
and performance of this Agreement and each other COLT 2007-SN1 Basic Document to
which the Servicer is a party have been duly authorized by the Servicer by all
necessary limited liability company action;

          (iv) Binding Obligation. This Agreement constitutes a legal, valid and
binding obligation of the Servicer enforceable in accordance with its terms,
except as enforceability may be limited by bankruptcy, insolvency,
reorganization, or other similar laws affecting the enforcement of creditors'
rights in general and by general principles of equity, regardless of whether
such enforceability is considered in a proceeding in equity or at law;

          (v) No Violation. The consummation of the transactions contemplated by
this Agreement and each other COLT 2007-SN1 Basic Document to which the Servicer
is a party, and the fulfillment of the terms of this Agreement and each other
COLT 2007-SN1 Basic Document to which the Servicer is a party, shall not
conflict with, result in any breach of any of the terms and provisions of, or
constitute (with or without notice or lapse of time) a default under, the
certificate of formation or limited liability company agreement of the Servicer,
or any indenture, agreement, mortgage, deed of trust or other instrument to
which the Servicer is a party or by which it is bound, result in the creation or
imposition of any Lien upon any of its properties pursuant to the terms of any
such indenture, agreement, mortgage, deed of trust or other instrument or
violate any law or, to the best of the Servicer's knowledge, any order, rule or
regulation applicable to the Servicer of any court or of any federal or State
regulatory body, administrative agency or other governmental instrumentality
having jurisdiction over the Servicer or any of its properties; and

          (vi) No Proceedings. There are no Proceedings pending or, to the
Servicer's knowledge, threatened, before any court, regulatory body,
administrative agency or other tribunal or governmental instrumentality having
jurisdiction over the Servicer or its properties (A) asserting the invalidity of
this Agreement or any other COLT 2007-SN1 Basic Document, (B) seeking to prevent
the issuance of the COLT 2007-SN1 Secured Notes or the consummation of any of
the transactions contemplated by this Agreement or any other COLT 2007-SN1 Basic
Document, or (C) seeking any determination or ruling that might materially and
adversely affect the performance by the Servicer of its obligations under, or
the validity or enforceability of, this Agreement or any other COLT 2007-SN1
Basic Document.

     SECTION 2.13 Purchase of Series 2007-SN1 Lease Assets Upon Breach of
Covenant.

     (a) Upon discovery by the Servicer, the COLT Owner Trustee or any Series
2007-SN1 Further Holder of a breach of any of the covenants set forth in
Sections 2.09, 2.11(a) and 2.12(a) that materially and adversely affects any
Series 2007-SN1 Lease Asset, the party discovering such breach shall give prompt
written notice to the others. As of the last day of the second Collection Period
following its discovering or receiving notice of such breach (or, at the
Servicer's election, the last day of the first Collection Period so following),
the Servicer shall,



unless it shall have cured such breach in all material respects, purchase from
COLT any Series 2007-SN1 Lease Asset materially and adversely affected by such
breach and, on or prior to the related Payment Date, the Servicer shall deposit
to the COLT Collection Account the Administrative Purchase Payment, and shall be
entitled to receive the Released Administrative Amount, if any. The obligation
of the Servicer to purchase any Series 2007-SN1 Lease Asset with respect to
which such a breach has occurred and is continuing shall, if such obligation is
fulfilled, constitute the sole remedy against the Servicer for such breach
available to the Series 2007-SN1 Further Holders or COLT.

     (b) Upon payment of the Administrative Purchase Payment with respect to any
Administrative Lease Asset pursuant to this Section 2.13, COLT shall assign to
the Servicer, without recourse, representation or warranty, all of COLT's right,
title and interest in and to such Series 2007-SN1 Lease Asset, all monies due
thereon, proceeds from insurance policies to the extent relating to such Series
2007-SN1 Lease Asset or the related Lessee and the interests of COLT in rebates
of premiums and other amounts relating to insurance policies to the extent
relating to such Series 2007-SN1 Lease Asset and any documents relating thereto,
such assignment being an assignment outright and not for security; and the
Servicer shall thereupon own the same free of all further obligation to COLT and
the Series 2007-SN1 Further Holders with respect thereto. The Servicer shall
then release its claim for reimbursement of the portion of any Outstanding
Advances made with respect to such Administrative Lease Asset.

     SECTION 2.14 Basic Servicing Fees; Additional Servicing Fees; Supplemental
Servicing Fees; Payment of Certain Expenses by Servicer.

     (a) On each Payment Date, the Servicer (or its designee) shall receive
Basic Servicing Fees and Additional Servicing Fees out of the Available
Distribution Amount in respect of the Series 2007-SN1 Lease Assets. The Servicer
(or its designee) shall receive the Supplemental Servicing Fee from any other
amounts on account thereof collected by the Servicer hereunder when and as paid
without any obligation to COLT or any Series 2007-SN1 Further Holder and shall
have no obligation to deposit any such amount in the COLT Collection Account. To
the extent that any amount of Supplemental Servicing Fees shall be held in the
COLT Collection Account or any other account established hereunder or under any
other COLT 2007-SN1 Basic Document, such amount shall be withdrawn therefrom and
paid to the Servicer (or its designee) upon presentation of a certificate signed
by a Responsible Officer of the Servicer setting forth, in reasonable detail,
the amount of such Supplemental Servicing Fee.

     (b) The Servicer shall pay from its own funds (including Basic Servicing
Fees and Additional Servicing Fees paid to it but excluding any property in the
COLT 2007-SN1 Trust Estate) all expenses incurred by it in connection with its

accordance



with Section 2.07(a), and (vii) all other fees and expenses not expressly stated
under this Agreement to be for the account of the COLT 2007-SN1 Secured
Noteholders or the COLT 2007-SN1 Certificateholder; provided, however, that the
Servicer shall be entitled to reimbursement in accordance with Sections 2.07(b)
and 3.03(b)(iii)(B) for any Liquidation Expenses incurred with respect to the
Series 2007-SN1 Lease Assets.

Nothing in this Section 2.18 shall derogate from the obligation of the Servicer
to observe any applicable law prohibiting disclosure of information regarding

Holder before such request indicating the removal of Lease Assets from the
Series 2007-SN1 Lease Assets.

     (i) pay costs associated with the appointment of a successor COLT Indenture

Documents, and at the request of the COLT Owner Trustee taking all appropriate
actions that it is the duty of COLT or the COLT Owner Trustee to take pursuant

supervise the performance of such other activities in connection with the COLT
2007-SN1 Collateral (including the COLT 2007-SN1 Basic Documents) as are not
covered by any of the foregoing provisions and as are expressly requested by the

the formalities required by the VAULT Trust Agreement.

                                   ARTICLE III
                    ESTABLISHMENT OF ACCOUNTS; DISTRIBUTIONS

     SECTION 3.01 Establishment of COLT Collection Account and Payment Ahead
Servicing Account.

     (a) The Servicer, for the benefit of the COLT 2007-SN1 Secured Noteholders,
shall establish and maintain in the name of the COLT Indenture Trustee an
Eligible Deposit Account known as the Central Originating Lease Trust 2007-SN1
Collection Account (the "COLT



Collection Account"), bearing an additional designation clearly indicating that
the funds deposited therein are held for the benefit of the Series 2007-SN1
Further Holders.

          (i) The Servicer, for the benefit of the Lessees, shall establish and
maintain in the name of the COLT Indenture Trustee an Eligible Deposit Account
known as the Central Originating Lease Trust COLT 2007-SN1 Payment Ahead
Servicing Account (the "Payment Ahead Servicing Account"). The Payment Ahead
Servicing Account shall not be property of COLT.

     (b) Each of the COLT 2007-SN1 Accounts shall be Eligible Deposit Accounts
initially established with the COLT Indenture Trustee and maintained by the
Servicer. At any time after the Series 2007-SN1 Closing Date, the Servicer, upon
30 days written notice to the COLT Indenture Trustee or other Account Holder,
shall have the right to instruct the COLT Indenture Trustee or other Account
Holder to transfer any or all of the COLT 2007-SN1 Accounts to another Eligible
Institution designated by the Servicer in such notice. No COLT 2007-SN1 Account
shall be maintained with an Account Holder if the short-term unsecured debt
obligations of such Account Holder cease to have the Required Deposit Rating
(except that any Designated Account may be maintained with an Account Holder
even if the short-term unsecured debt obligations of such Account Holder do not
have the Required Deposit Rating, if such Account Holder maintains such
Designated Account in its corporate trust department). Should an Account Holder
no longer satisfy the requirements in the preceding sentence with respect to any
Designated Account, then the Servicer shall, within ten Business Days (or such
longer period, not to exceed 30 calendar days), with the Account Holder's
assistance as necessary, cause each affected COLT 2007-SN1 Account (A) to be
moved to an Account Holder that is an Eligible Institution or (B) with respect
to the Designated Accounts only, to be moved to the corporate trust department
of the Account Holder. All amounts held in COLT 2007-SN1 Accounts shall, to the
extent permitted by applicable laws, rules and regulations, be invested, at the
written direction of the Servicer, by such Account Holder in Eligible
Investments. Such written direction shall constitute certification by the
Servicer that any such investment is authorized by this Section 3.01. Such
direction may be a standing direction to invest all funds from time to time on
deposit in an account in a particular Eligible Investment until subsequent
notice from the Servicer. If the Servicer has not provided such prior written
direction to the Account Holder, the Account Holder shall invest uninvested
funds in "BNY-Hamilton MMF Instit #746." Investments in Eligible Investments
shall be made in the name of the COLT Indenture Trustee or its nominee or
assignee and, unless otherwise permitted by the Rating Agencies, may not be sold
or disposed of prior to their maturity; provided, however, that Eligible
Investments held in the COLT 2007-SN1 Reserve Account may be sold or disposed of
prior to their maturity so long as (x) the Servicer directs the COLT Indenture
Trustee to make such sale or disposition, and (y) the Eligible Investments are
sold at a price equal to or greater than the unpaid principal balance thereof.
Investment Earnings on funds deposited in the COLT 2007-SN1 Accounts shall be
payable to the Servicer as Supplemental Servicing Fees. Neither the COLT Owner
Trustee nor the COLT Indenture Trustee shall have any liability for any loss on
Eligible Investments, nor shall the COLT Owner Trustee or the COLT Indenture
Trustee have any liability for transferring funds in or to the COLT 2007-SN1
Accounts based on written instructions of the Servicer. Each Account Holder
holding a COLT 2007-SN1 Account as provided in this Section 3.01(b) shall be a
"Securities Intermediary." If a Securities Intermediary shall be a Person other
than the COLT Indenture Trustee, the Servicer shall obtain the express



agreement of such Person to the obligations of the Securities Intermediary set
forth in this Section 3.01 and an Opinion of Counsel that such Person can
perform such obligations and the Servicer shall send a copy of such agreement
and Opinion of Counsel to the COLT Indenture Trustee.

     (c) With respect to the Designated Account Property, each of the Account
Holder and the Servicer, as applicable, hereby agrees that:

          (i) any Designated Account Property that is held in deposit accounts
shall be held solely in Eligible Deposit Accounts; and each such Eligible
Deposit Account shall be subject to the exclusive custody and control of the
Designated Account Owner, and the Designated Account Owner or the Servicer on
its behalf shall have sole authority to direct payments with respect thereto;

          (ii) any Designated Account Property that constitutes Physical
Property shall be delivered to the Designated Account Owner in accordance with
paragraph (i) of the definition of "Delivery" and shall be held, pending
maturity or disposition, solely by the Designated Account Owner or a securities
intermediary (as such term is defined in 8-102(a)(14) of the UCC) acting solely
for the Designated Account Owner;

          (iii) any Designated Account Property that is a book-entry security
held through the Federal Reserve System pursuant to federal book-entry
regulations shall be delivered in accordance with paragraph (ii) of the
definition of "Delivery" and shall be maintained by the Designated Account
Owner, pending maturity or disposition, through continued book-entry
registration of such Designated Account Property as described in such paragraph;

          (iv) any Designated Account Property that is an "uncertificated
security" (as such term is defined in 8-102(a)(18) of the UCC) and that is not
governed by clause (iii) above shall be delivered to the Designated Account
Owner in accordance with paragraph (iii) of the definition of "Delivery" and
shall be maintained by the Designated Account Owner or its nominee or custodian,
pending maturity or disposition, through continued registration of the
Designated Account Owner's (or its nominee's or custodian's) ownership of such
security;

          (v) each Account Holder shall maintain each item of Designated Account
Property in the particular Designated Account to which such item originated and
shall not commingle items from different Designated Accounts; and

          (vi) the Servicer agrees to take or cause to be taken such further
actions, to execute, deliver and file or cause to be executed, delivered and
filed such further documents and instruments (including any UCC financing
statements or this Agreement) as may be necessary in order to perfect the
interests of the Designated Account Owner in the Designated Account Property
including to promptly execute, deliver and file any financing statements,
amendments, continuation statements, assignments, certificates and other
documents with respect to such interests and to perform all such other acts as
may be necessary in order to perfect or to maintain the perfection of the
Designated Account Owner's security interest.



     (d) The Servicer shall have the power, revocable by the COLT Indenture
Trustee, to make withdrawals and payments from the Designated Accounts for the
purpose of permitting the Servicer or the COLT Indenture Trustee to carry out
their respective duties hereunder.

     (e) The COLT Indenture Trustee shall possess all right, title and interest
in and to all funds on deposit from time to time in the Designated Accounts and
in all proceeds thereof (except Investment Earnings). Except as otherwise
provided herein, the Designated Accounts shall be under the exclusive dominion
and control of the COLT Indenture Trustee for the benefit of the COLT 2007-SN1
Secured Noteholders and the COLT Indenture Trustee shall have sole signature
power and authority with respect thereto.

     (f) The COLT Indenture Trustee, each Account Holder and each other Eligible
Deposit Institution with whom a Designated Account is maintained waives any
right of set-off, counterclaim, security interest or bankers' lien to which it
might otherwise be entitled.

     (g) At any time that the Monthly Remittance Condition is satisfied, then
(x) Payments Ahead need not be remitted to and deposited in the Payment Ahead
Servicing Account but instead may be remitted to and held by the Servicer and
(y) the Servicer shall not be required to segregate or otherwise hold separate
any Payments Ahead, but the Servicer shall be required to remit Applied Payments
Ahead to the COLT Collection Account in accordance with Section 3.03(b)(ii). The
Servicer shall promptly notify the COLT Indenture Trustee if the Monthly
Remittance Condition ceases to be satisfied. Commencing with the first day of
the first Collection Period that begins at least two Business Days after the day
on which the Monthly Remittance Condition ceases to be satisfied, the Servicer
shall deposit in the Payment Ahead Servicing Account the amount of any Payments
Ahead then held by it, and thereafter, for so long as the Monthly Remittance
Condition continues to be unsatisfied, the Servicer shall deposit any additional
Excess Payments in the Payment Ahead Servicing Account within two Business Days
after receipt thereof. Notwithstanding the foregoing, if the Monthly Remittance
Condition ceases to be satisfied the Servicer may utilize, with respect to any
Payments Ahead then held by it and any additional Excess Payments that it may
subsequently receive, an alternative remittance schedule (which may include a
remittance schedule utilized by the Servicer at a time when the Monthly
Remittance Condition was satisfied), if the Servicer provides the COLT Indenture
Trustee (x) written consent of the COLT 2007-SN1 Secured Noteholders to such
alternative remittance schedule and (y) written confirmation from the Rating
Agencies that such alternative remittance schedule will not result in the
downgrading or withdrawal by the Rating Agencies of the ratings then assigned to
the Rated Notes. The COLT Indenture Trustee shall be deemed to have no knowledge
of any Servicer Default unless such trustee has received notice of such event or
circumstance from the Seller, the Servicer, or the COLT 2007-SN1 Secured
Noteholders or unless a Responsible Officer of the COLT Indenture Trustee with
knowledge hereof and familiarity herewith has actual knowledge of such event or
circumstance.

     SECTION 3.02 Reserve Account.

     (a) The Servicer, for the benefit of the COLT 2007-SN1 Secured Noteholders,
shall establish and maintain in the name of the COLT Indenture Trustee an
Eligible Deposit Account known as the Central Originating Lease Trust COLT
2007-SN1 Reserve Account (the "Reserve Account"), bearing an additional
designation clearly indicating that the funds deposited therein



are held for the benefit of the Series 2007-SN1 Further Holders, which shall
include the money and other property deposited and held therein pursuant to this
Section 3.02(a) and Section 3.03(c)(v). On the Series 2007-SN1 Closing Date,
COLT, LLC shall deposit the Reserve Account Initial Deposit in immediately
available funds into the Reserve Account. The Reserve Account shall be a part of
the COLT 2007-SN1 Trust Estate.

     (b) After giving effect to all deposits into or withdrawals from the
Reserve Account on any Payment Date and except as otherwise directed in writing
by COLT, LLC (in its sole discretion), the Servicer shall pay to the COLT
2007-SN1 Certificateholder the Reserve Account Excess Amount on such Payment
Date.

     SECTION 3.03 Distributions.

     (a) On or before each Determination Date, the Servicer shall calculate the
Available Distribution Amount, the Basic Servicing Fee, the Additional Servicing
Fee, the Aggregate Noteholders' Principal Distributable Amount, the Reserve
Account Required Amount, the Reserve Account Available Amount, the Secured Note
Principal Balance for each COLT 2007-SN1 Secured Note, the Aggregate Secured
Note Principal Balance, the Secured Note Monthly Accrued Interest, the Secured
Note Interest Distributable Amount, the Secured Note Principal Distributable
Amount, the CARAT Collection Account Shortfall Amount, the aggregate Outstanding
Advances and all other amounts required to determine the amounts, if any, to be
deposited into or paid from each of the COLT Collection Account, the Reserve
Account and the Payment Ahead Servicing Account on or before the related Payment
Date. On or before each Determination Date, the Servicer shall deliver to the
COLT Indenture Trustee a written report specifying the amounts calculated by the
Servicer pursuant to this Section 3.03(a). The COLT Indenture Trustee shall be
entitled to rely solely upon such report from the Servicer in making any and all
transfers, withdrawals, deposits and distributions pursuant to this Section
3.03.

     (b) On or before each Payment Date, the COLT Indenture Trustee shall
withdraw collections made during the related Collection Period that constitute
Excess Payments from the COLT Collection Account (to the extent such amounts
have not been retained by the Servicer pursuant to Section 3.01(g)) and pay such
amounts to the Servicer, who shall retain such Excess Payments amounts for its
own account, or, if the Monthly Remittance Condition is not satisfied, the COLT
Indenture Trustee, upon written instruction of the Servicer, shall deposit such
amounts into the Payment Ahead Servicing Account.

          (i) On or before each Payment Date, the COLT Indenture Trustee shall
transfer from the Payment Ahead Servicing Account (or, if the Servicer is not
required to make deposits to the Payment Ahead Servicing Account on a daily
basis pursuant to Section 3.01(g), the Servicer shall deposit) to the COLT
Collection Account the aggregate Applied Payments Ahead for such Payment Date.

          (ii) On or before each Payment Date, the COLT Indenture Trustee shall
withdraw from the COLT Collection Account and pay to the Servicer an amount
equal to the sum of (A) any Outstanding Advances with respect to which the
Servicer is entitled to reimbursement pursuant to Section 3.06(c) or (d) (to the
extent the Servicer has deposited such amounts into the COLT Collection Account
and to the extent the Servicer has not been



previously reimbursed for any such Outstanding Advances pursuant to Section
3.05(a)), and (B) any Liquidation Expenses (and any unpaid Liquidation Expenses
from prior periods) relating to Series 2007-SN1 Lease Assets with respect to
which the Servicer has sold or otherwise disposed of the related Vehicle during
or prior to the related Collection Period (if the Servicer has not yet deducted
such amounts from Sale Proceeds and has deposited such amounts into the COLT
Collection Account).

          (iii) On each Payment Date, the COLT Indenture Trustee shall withdraw
from the Reserve Account, and deposit into the COLT Collection Account, an
amount equal to the lesser of (I) the excess, if any, of (A) the sum, for such
Payment Date, of the amounts specified in clauses (i) through (iv) of Section
3.03(c), over (B) the excess of (i) the sum of (x) the COLT Collections with
respect to the Series 2007-SN1 Lease Assets on such Payment Date, plus (y) the
Applied Extended Lease Payment Amount for such Payment Date, over (ii) the sum
of (x) the amounts withdrawn from the COLT Collection Account with respect to
such Payment Date pursuant to Section 3.03(b)(iii), plus (y) the Unapplied
Extended Lease Payment Amount for such Payment Date, and (II) the Reserve
Account Available Amount on such Payment Date.

     (c) On each Payment Date, after the withdrawals, deposits and transfers
specified in Section 3.03(b) have been made, to the extent of the Available
Distribution Amount for such Payment Date, the COLT Indenture Trustee shall make
the following distributions from amounts deposited into the COLT Collection
Account in the following order of priority:

          (i) first, to the Servicer, the Basic Servicing Fee for the related
Collection Period (to the extent such Basic Servicing Fee has not been retained
by the Servicer pursuant to Section 3.04(b)) and any unpaid Basic Servicing Fees
from any preceding Payment Date;

          (ii) second, to the COLT 2007-SN1 Secured Noteholders, pro rata based
on the Secured Note Interest Distributable Amount due on each such COLT 2007-SN1
Secured Note, the Aggregate Secured Note Interest Distributable Amount due on
the COLT 2007-SN1 Secured Notes on such Payment Date;

          (iii) third, to the COLT 2007-SN1 Secured Noteholders, pro rata based
on the Secured Note Principal Balance of each COLT 2007-SN1 Secured Note, the
Secured Note Principal Distributable Amount payable on the COLT 2007-SN1 Secured
Notes on such Payment Date;

          (iv) fourth, to the CARAT Collection Account, the CARAT Collection
Account Shortfall Amount, if any, for such Payment Date;

          (v) fifth, to the Reserve Account, an amount necessary to cause the
Reserve Account Available Amount (after giving effect to any withdrawal from the
Reserve Account pursuant to Section 3.03(b)(iv) on such Payment Date) to equal
the Reserve Account Required Amount on such Payment Date;

          (vi) sixth, to the Servicer, an amount equal to the Additional
Servicing Fee, if any, on such Payment Date; and



          (vii) seventh, the remainder shall be distributed in accordance with
the instructions of the COLT 2007-SN1 Certificateholder delivered from time to
time.

     (d) The parties hereto hereby agree that this Section 3.03 shall supercede
Section 4.1 of the VAULT Trust Agreement with respect to the Series 2007-SN1
Lease Assets.

     SECTION 3.04 COLT Collections.

     (a) If the Monthly Remittance Condition is not satisfied, commencing with
the first day of the first Collection Period that begins at least two Business
Days after the day on which the Monthly Remittance Condition ceases to be
satisfied the Servicer shall remit to the COLT Collection Account all COLT
Collections within two Business Days after receipt thereof; provided, however,
that the Servicer shall deposit into the COLT Collection Account any Pull Ahead
Payments it receives from GMAC, as agent for General Motors, pursuant to Section
2.02(b) on the same day as such payments are received. Notwithstanding the
foregoing, if the Monthly Remittance Condition is unsatisfied, the Servicer may
utilize an alternative remittance schedule (which may include a remittance
schedule utilized by the Servicer at a time when the Monthly Remittance
Conditions was satisfied), if the Servicer provides the COLT Indenture Trustee
(x) written instruction to follow such alternative remittance schedule and (y)
written confirmation from the Rating Agencies that such alternative remittance
schedule will not result in the downgrading or withdrawal by the Rating Agencies
of the ratings then assigned to the Rated Notes. At all times when the Monthly
Remittance Condition is satisfied, the Servicer (i) shall not be required to
segregate or otherwise hold separate any COLT Collections and Payments Ahead
received on the Series 2007-SN1 Lease Assets and (ii) shall remit an amount
equal to the COLT Collections received during a Collection Period to the COLT
Collection Account in immediately available funds on or before the related
Payment Date.

     (b) Notwithstanding anything to the contrary contained in this Agreement,
for so long as the Monthly Remittance Condition has been satisfied, the Servicer
shall be permitted to retain the Basic Servicing Fee, any Payments Ahead and
reimbursement for any Outstanding Advances and shall deposit into the COLT
Collection Account on each Payment Date only the COLT Collections received by
the Servicer on the Series 2007-SN1 Lease Assets during the related Collection
Period net of amounts to be distributed to or retained by the Servicer on
account of the Basic Servicing Fee, any Excess Payments and reimbursement of any
Outstanding Advances on the following Payment Date. The Servicer shall, however,
account for all COLT Collections as if all of the deposits and distributions
described herein were made individually.

     SECTION 3.05 Application of COLT Collections. For the purposes of this
Agreement and the other COLT 2007-SN1 Basic Documents, all COLT Collections with
respect to a Series 2007-SN1 Lease Asset for each Collection Period shall be
applied by the Servicer no later than the related Payment Date as follows:

     (a) With respect to each Series 2007-SN1 Lease Asset (other than an
Administrative Lease Asset, a Warranty Lease Asset or an Extended Lease),
payments by or on behalf of the Lessee that are not Supplemental Servicing Fees,
Excluded Amounts or Sales and Use Tax Amounts shall be applied first to reduce
any Outstanding Advances made pursuant to this Agreement with respect to such
Series 2007-SN1 Lease Asset. Second, the amount of any such



payments that are not Supplemental Servicing Fees, Excluded Amounts or Sales and
Use Tax Amounts in excess of any such Outstanding Advances with respect to such
Series 2007-SN1 Lease Asset shall be applied to the Monthly Lease Payment with
respect to such Series 2007-SN1 Lease Asset. With respect to any Series 2007-SN1
Lease Asset and any Collection Period, the "Excess Payment" shall equal the
excess, if any, of (x) the amount of the payments made by or on behalf of the
related Lessee and received during such Collection Period (other than any
prepayment in full in connection with a termination of the related Series
2007-SN1 Lease prior to its Scheduled Lease End Date) that are not Supplemental
Servicing Fees, Excluded Amounts, Sales and Use Tax Amounts or Applied Payments
Ahead, over (y) the amounts applied with respect to such Series 2007-SN1 Lease
Asset pursuant to the two preceding sentences. If the amounts applied under the
first two sentences of this Section 3.05(a) shall be less than the Monthly Lease
Payment, whether as a result of any extension granted to the Lessee or
otherwise, then an amount equal to the Applied Payments Ahead, if any, with
respect to such Series 2007-SN1 Lease Asset shall be applied by the Servicer to
the extent of the shortfall, and the Payments Ahead with respect to such Series
2007-SN1 Lease Asset shall be reduced accordingly.

     (b) With respect to each Administrative Lease Asset and Warranty Lease
Asset, payments by or on behalf of the Lessee shall be applied in the same
manner in accordance with Section 3.05(a), except that any Released
Administrative Amount or Released Warranty Amount shall be remitted to the
Servicer or the Seller, as applicable. Any Warranty Payment shall be applied to
reduce any Outstanding Advances and such Warranty Payment or an Administrative
Purchase Payment, as applicable, shall be applied to the Monthly Lease Payment,
in each case to the extent that the payments by or on behalf of the Lessee shall
be insufficient, and then to prepay such Series 2007-SN1 Lease Asset in full.

     (c) With respect to each Extended Lease, payments by or on behalf of the
Lessee that are not Supplemental Servicing Fees, Excluded Amounts or Sales and
Use Tax Amounts shall be applied first to reduce any Outstanding Advances made
pursuant to this Agreement with respect to such Series 2007-SN1 Lease Asset.
Second, the amount of any such payments that are not Supplemental Servicing
Fees, Excluded Amounts or Sales and Use Tax Amounts in excess of any such
Outstanding Advances with respect to such Extended Lease shall be applied to the
Extended Lease Payment with respect to such Extended Lease.

     SECTION 3.06 Advances.

     (a) Subject to the following sentence, with respect to each Collection
Period and each Series 2007-SN1 Lease (other than an Administrative Lease Asset,
a Warranty Lease Asset or an Extended Lease), if there is a shortfall in the
Monthly Lease Payment remaining after application of the Applied Payments Ahead
pursuant to Section 3.05(a), the Servicer, in its sole discretion, may (but
shall have no obligation to) advance an amount equal to such shortfall (such
amount, a "Monthly Payment Advance") on the second Business Day of the following
Collection Period or, if the Monthly Remittance Condition is satisfied, on the
Business Day preceding the related Payment Date. The Servicer may make a Monthly
Payment Advance in respect of a Series 2007-SN1 Lease only to the extent that
the Servicer, in its sole discretion, shall determine that such Monthly Payment
Advance shall be recoverable from subsequent collections or recoveries on such
Series 2007-SN1 Lease Asset.



     (b) With respect to each Collection Period and each Series 2007-SN1 Lease
(i) which terminated by reason of having reached its Scheduled Lease End Date
120 days or more prior to the last day of such Collection Period, and (ii) for
which the related Vehicle has not been sold during or prior to such Collection
Period, the Servicer, in its sole discretion, may (but shall have no obligation
to) advance, on the second Business Day of the following Collection Period or,
if the Monthly Remittance Condition is satisfied, on the related Payment Date,
an amount (the "Residual Advance") equal to the lesser of (x) the Lease Residual
for the related Vehicle, reduced, in the case of any Series 2007-SN1 Lease Asset
that is an Extended Lease, by the aggregate amount of any Extended Lease
Payments on such Series 2007-SN1 Lease Asset received by the Servicer since the
Scheduled Lease End Date of such Series 2007-SN1 Lease Asset, and (y) the amount
that the Servicer, in its sole discretion, has estimated shall be recoverable
from the sale or other disposition of the Vehicle related to such Series
2007-SN1 Lease.

     (c) The Servicer shall be reimbursed for Outstanding Advances with respect
to a Series 2007-SN1 Lease Asset from subsequent COLT Collections and recoveries
received with respect to such Series 2007-SN1 Lease Asset.

     (d) If the sources specified in Section 3.06(c) are insufficient to
reimburse all Outstanding Advances with respect to a Series 2007-SN1 Lease upon
collection of all amounts expected by the Servicer to be collected with respect
to such Series 2007-SN1 Lease and the related Vehicle, then the Servicer shall
be entitled to reimbursement of any remaining Outstanding Advances with respect
to such Series 2007-SN1 Lease from COLT Collections and recoveries on any other
Series 2007-SN1 Lease Assets.

                                   ARTICLE IV
                                  THE SERVICER

     SECTION 4.01 Liability of Servicer; Indemnities.

     (a) The Servicer shall be liable in accordance with this Agreement only to
the extent of the obligations in this Agreement specifically undertaken by the
Servicer. Such obligations shall include the following:

          (i) The Servicer shall indemnify, defend and hold harmless COLT, the
COLT Indenture Trustee and the COLT Owner Trustee from and against any taxes
that may at any time be asserted against any such Person with respect to the
transactions contemplated in the COLT 2007-SN1 Basic Documents, including any
sales, use, gross receipts, general corporation, tangible personal property,
privilege or license taxes (but not including any taxes asserted with respect
to, and as of the date of, the sale of the Series 2007-SN1 Lease Assets to COLT
or the issuance and original sale of the COLT 2007-SN1 Certificates or the COLT
2007-SN1 Secured Notes, or asserted with respect to ownership of the Series
2007-SN1 Lease Assets (for the avoidance of doubt such excluded taxes shall not
include Sales and Use Tax Amounts), or federal or other income taxes arising out
of distributions on the COLT 2007-SN1 Certificates or COLT 2007-SN1 Secured
Notes, or any fees or compensation payable to any such Person) and costs and
expenses in defending against the same.



          (ii) The Servicer shall defend, indemnify and hold harmless COLT, the
COLT Owner Trustee, the COLT Indenture Trustee and each Series 2007-SN1 Further
Holder (each of the foregoing, an "Indemnified Person") from and against any and
all costs, expenses, losses, damages, claims and liabilities arising out of or
resulting from the use or operation by the Lessee or by the Servicer or any
Affiliate of the Servicer, of any Vehicle related to a Series 2007-SN1 Lease
Asset.

          (iii) The Servicer shall indemnify, defend and hold harmless the
Indemnified Persons from and against any and all costs, expenses, losses,
claims, damages and liabilities to the extent that such cost, expense, loss,
claim, damage or liability arose out of, or was imposed upon any such
Indemnified Person through the negligence, willful misfeasance or bad faith of
the Servicer in the performance of its duties under this Agreement or under any
other COLT 2007-SN1 Basic Document, or by reason of reckless disregard of its
obligations and duties under this Agreement or any other COLT 2007-SN1 Basic
Documents.

          (iv) The Servicer shall indemnify, defend and hold harmless the COLT
Indenture Trustee, the COLT Owner Trustee and their respective agents and
servants from and against all costs, expenses, losses, claims, damages and
liabilities arising out of or incurred in connection with (x) in the case of the
COLT Owner Trustee, the COLT Indenture Trustee's performance of its duties under
the COLT Indenture and any other COLT 2007-SN1 Basic Documents, (y) in the case
of the COLT Indenture Trustee, the COLT Owner Trustee's performance of its
duties under the Declaration of Trust or (z) the acceptance, administration or
performance by, or action or inaction of, the COLT Owner Trustee or the COLT
Indenture Trustee, as applicable, of the trusts and duties contained in this
Agreement or the other COLT 2007-SN1 Basic Documents, including the
administration of the COLT 2007-SN1 Trust Estate, except to the extent that such
cost, expense, loss, claim, damage or liability: (A) is due to the willful
misfeasance, bad faith or negligence (except for errors in judgment) of the
Person indemnified, (B) to the extent otherwise payable to the COLT Owner
Trustee, arises from the COLT Owner Trustee's breach of any of its
representations or warranties set forth in Section 5.6 of the Declaration of
Trust, (C) to the extent otherwise payable to the COLT Indenture Trustee, arises
from the COLT Indenture Trustee's breach of any of its representations or
warranties set forth in the COLT Indenture or (D) arises out of or is incurred
in connection with the performance by the COLT Indenture Trustee of the duties
of successor Servicer hereunder.

     (b) Indemnification under this Section 4.01 shall include reasonable fees
and expenses of external counsel and expenses of litigation. If the Servicer has
made any indemnity payments pursuant to this Section 4.01 and the recipient
thereafter collects any of such amounts from others, the recipient shall
promptly repay such amounts collected to the Servicer, without interest.

     SECTION 4.02 Merger or Consolidation of, or Assumption of the Obligations
of, the Servicer. Any corporation or other entity

     (a) into which the Servicer may be merged or consolidated,

     (b) resulting from any merger, conversion or consolidation to which the
Servicer shall be a party,



     (c) succeeding to the business of the Servicer, or

     (d) more than 50% of the voting stock (or, if not a corporation, other
voting interests) of which is owned, directly or indirectly, by GMAC or General
Motors and which services assets of the same type as the Series 2007-SN1 Lease
Assets,

which entity in any of the foregoing cases executes an agreement of assumption
to perform every obligation of the Servicer under this Agreement and the Further
Transfer and Administration Agreements, shall be the successor to the Servicer
under this Agreement without the execution or filing of any paper or any further
act on the part of any of the parties to this Agreement, anything in this
Agreement, to the contrary notwithstanding. The Servicer shall provide notice of
any merger, conversion, consolidation or succession pursuant to this Section
4.02 to the COLT Indenture Trustee, the COLT Owner Trustee and, if any Rated
Notes are outstanding, the Rating Agencies.

     SECTION 4.03 Limitation on Liability of Servicer and Others.

     (a) Neither the Servicer nor any of the directors or officers or employees
or agents of the Servicer shall be under any liability to COLT or any
Indemnified Person, except as specifically provided in this Agreement, for any
action taken or for refraining from the taking of any action pursuant to this
Agreement or any other COLT 2007-SN1 Basic Document, or for errors in judgment;
provided, however, that this provision shall not protect the Servicer or any
such Person against any liability that would otherwise be imposed by reason of
willful misfeasance, bad faith or negligence (except errors in judgment) in the
performance of duties or by reason of reckless disregard of obligations and
duties under this Agreement or any other COLT 2007-SN1 Basic Document. The
Servicer and any director, officer or employee or agent of the Servicer may rely
in good faith on the advice of counsel or on any document of any kind prima
facie properly executed and submitted by any Person respecting any matters
arising under this Agreement.

     (b) The Servicer and any director, officer, employee or agent of the
Servicer shall be reimbursed by (x) the COLT Owner Trustee for any contractual
damages, liability or expense incurred by reason of the COLT Owner Trustee's
willful misfeasance, bad faith or negligence (except errors in judgment) in the
performance of the COLT Owner Trustee's duties under this Agreement, the COLT
Indenture, or the Declaration of Trust or by reason of reckless disregard of its
obligations and duties under this Agreement, the COLT Indenture, or the
Declaration of Trust, and (y) the COLT Indenture Trustee for any contractual
damages, liability or expense incurred by reason of the COLT Indenture Trustee's
willful misfeasance, bad faith or negligence (except errors in judgment) in the
performance of the COLT Indenture Trustee's duties under this Agreement or any
other COLT 2007-SN1 Basic Documents or by reason of reckless disregard of its
obligations and duties under this Agreement or any other COLT 2007-SN1 Basic
Documents. In no event, however, shall the COLT Indenture Trustee or the COLT
Owner Trustee be liable to the Servicer for any damages in the nature of
special, indirect or consequential damages, however styled, including lost
profits, even if either or both of them have been advised of the likelihood of
such loss or damage.



     (c) Except as provided in this Agreement, the Servicer shall not be under
any obligation to appear in, prosecute or defend any legal action that is not
incidental to its duties to service the Series 2007-SN1 Lease Assets in
accordance with this Agreement and that in its opinion may involve it in any
expense or liability; provided, however, that the Servicer may undertake any
reasonable action that it may deem necessary or desirable in respect of this
Agreement or any other COLT 2007-SN1 Basic Document and the rights and duties of
the parties to this Agreement and the interests of the Series 2007-SN1 Further
Holders under this Agreement. In such event, the reasonable legal expenses and
costs for such action and any liability resulting therefrom shall be payable
from collections received on the Series 2007-SN1 Lease Assets and the Servicer
shall be entitled to reimbursement therefor.

     SECTION 4.04 Delegation of Duties. So long as GMAC acts as Servicer, the
Servicer may, at any time without notice or consent, delegate any duties under
this Agreement to General Motors or any corporation more than 50% of the voting
stock of which is owned, directly or indirectly, by General Motors or GMAC. The
Servicer may at any time perform specific duties as servicer through
sub-contractors who are in the business of servicing automotive retail leases.
No such delegation shall relieve the Servicer of its responsibility with respect
to such duties.

     SECTION 4.05 Servicer Not to Resign. Subject to the provisions of Section
4.02, the Servicer shall not resign from the obligations and duties imposed on
it by this Agreement as Servicer except (x) upon determination that the
performance of its duties under this Agreement is no longer permissible under
applicable law or (y) upon determination by the board of directors of the
Servicer that by reason of change in applicable legal requirements the continued
performance by the Servicer of its duties as Servicer under this Agreement would
cause it to be in violation of such legal requirements in a manner that would
result in a material adverse effect on the Servicer or its financial condition,
said determination to be evidenced by resolutions of the board of directors to
such effect (provided that any Servicer other than GMAC may resign if upon such
resignation another successor Servicer will perform the duties of Servicer
hereunder and such Servicer has been approved by the holders of a majority of
the then outstanding principal amount of COLT 2007-SN1 Secured Notes). Any such
determination permitting the resignation of the Servicer shall be evidenced by
an Opinion of Counsel to such effect delivered to each of the Series 2007-SN1
Further Holders. No such resignation shall become effective until and unless the
COLT Indenture Trustee or a successor Servicer shall have entered into a
servicing agreement with COLT, such agreement to have substantially the same
provisions of this Agreement. COLT shall not unreasonably fail to consent to
such a servicing agreement. The resigning Servicer shall promptly provide notice
of its resignation to each of the Rating Agencies and Series 2007-SN1 Further
Holders.

                                    ARTICLE V
                                SERVICER DEFAULTS

     SECTION 5.01 Servicer Defaults. For purposes of this Agreement, each of the
following shall constitute a "Servicer Default":

     (a) any failure by the Servicer to deposit any required distribution,
payment, transfer or deposit into any COLT 2007-SN1 Account (including, with
respect to GMAC as Servicer, to obtain and deposit Pull Ahead Payments under
Section 2.02(b), and, with respect to any



successor Servicer, to deposit such amounts, if obtained, pursuant to Section
2.02(b)) or to direct the COLT Indenture Trustee to make any required
distributions from any COLT 2007-SN1 Account, which failure continues unremedied
for a period of five Business Days after (x) written notice thereof is received
by the Servicer or (y) discovery of such failure by an officer of the Servicer;

     (b) any failure on the part of the Servicer to duly observe or perform in
any material respect any other covenants or agreements of the Servicer set forth
in this Agreement or in any other COLT 2007-SN1 Basic Document, which failure
(i) materially and adversely affects the rights of the COLT 2007-SN1 Secured
Noteholder, and (ii) continues unremedied for a period of 90 days after (x) the
date on which written notice of such failure shall have been given to the
Servicer or (y) discovery of such failure by an officer of the Servicer;

     (c) the entry of a decree or order by a court or agency or supervisory
authority having jurisdiction in the premises for the appointment of a
conservator, receiver or liquidator for the Servicer, in any insolvency,
readjustment of debt, marshalling of assets and liabilities or similar
proceedings, or for the winding up or liquidation of their respective affairs,
and the continuance of any such decree or order unstayed and in effect for a
period of 90 consecutive days; or

     (d) the consent by the Servicer to the appointment of a conservator or
receiver or liquidator in any insolvency, readjustment of debt, marshalling of
assets and liabilities, or similar proceedings of or relating to the Servicer or
of or relating to substantially all of its property; or the Servicer shall admit
in writing its inability to pay its debts generally as they become due, file a
petition to take advantage of any applicable insolvency or reorganization
statute, make an assignment for the benefit of its creditors or voluntarily
suspend payment of its obligations.

     Notwithstanding the foregoing, there shall be no Servicer Default where a
Servicer Default would otherwise exist under clause (a) above for a period of
ten Business Days or under clause (b) for a period of 60 days if the delay or
failure giving rise to the default was caused by an act of God or other similar
occurrence. Upon the occurrence of any of those events, the Servicer shall not
be relieved from using its best efforts to perform its obligations in a timely
manner in accordance with the terms of this Agreement and the COLT Sale and
Contribution Agreement and the Servicer shall provide the COLT Indenture
Trustee, the COLT Owner Trustee, COLT, LLC and the CARAT Indenture Trustee, as
holder of the COLT 2007-SN1 Secured Notes, prompt notice of that failure or
delay by it, together with a description of its efforts to so perform its
obligations.

     SECTION 5.02 Consequences of a Servicer Default.

     (a) If a Servicer Default has occurred and is continuing, the COLT
Indenture Trustee may terminate all of the rights and obligations of the
Servicer under this Agreement but any such termination shall not relieve the
Servicer for any liability that accrued prior to such termination. On or after
the receipt by the Servicer of such written notice, all authority and power of
the Servicer under this Agreement, whether with respect to the Series 2007-SN1
Lease Assets or otherwise, shall pass to and be vested in the COLT Indenture
Trustee pursuant to and under this Section 5.02. The COLT Indenture Trustee is
authorized and empowered by this Agreement to execute and deliver, on behalf of
the Servicer, as attorney-in-fact or otherwise, any and all



documents and other instruments, and to do or accomplish all other acts or
things necessary or appropriate to effect the purposes of such notice of
termination, whether to complete the transfer and endorsement of the Series
2007-SN1 Lease Assets and related documents, or otherwise. The Servicer agrees
to cooperate with the COLT Indenture Trustee in effecting the termination of the
responsibilities and rights of the Servicer under this Agreement, including the
transfer to the COLT Indenture Trustee for administration by it of all cash
amounts that shall at the time be held by the Servicer for deposit, or have been
deposited by the Servicer, in the COLT 2007-SN1 Accounts or thereafter received
with respect to the Series 2007-SN1 Lease Assets and all Payments Ahead that
shall at that time be held by the Servicer or deposited in the Payment Ahead
Servicing Account.

     (b) The termination of the Servicer under Section 5.02(a) above shall also
result in the termination of the Custodian under the Custodian Agreement.

     SECTION 5.03 COLT Indenture Trustee to Act; Appointment of Successor. On
and after the time the rights and obligations of the Servicer are terminated
pursuant to Section 5.02, the COLT Indenture Trustee shall be the successor in
all respects to the Servicer in its capacity as servicer under this Agreement
and the transactions set forth or provided for in this Agreement, and shall be
subject to all the responsibilities, restrictions, duties and liabilities
relating thereto placed on the Servicer by the terms and provisions of this
Agreement. As compensation therefor, the COLT Indenture Trustee shall be
entitled to such compensation as the Servicer would have been entitled to under
this Agreement if no such notice of termination had been given, including the
Basic Servicing Fee, the Additional Servicing Fee and the Supplemental Servicing
Fee. Notwithstanding the above, the COLT Indenture Trustee may, if it shall be
unwilling so to act, or shall, if it is legally unable so to act, appoint, or
petition a court of competent jurisdiction to appoint, a successor (i) having a
net worth of not less than $100,000,000, (ii) having a long-term unsecured debt
rating from Moody's of at least "Baa3" (unless such requirement is expressly
waived by Moody's) and (iii) whose regular business includes the servicing of
automotive receivables, as the successor to the Servicer under this Agreement in
the assumption of all or any part of the responsibilities, duties or liabilities
of the Servicer under this Agreement. In connection with such appointment and
assumption, the COLT Indenture Trustee may make such arrangements for the
compensation of such successor out of payments on Series 2007-SN1 Lease Assets
as it and such successor shall agree; provided, however, that no such
compensation shall be in excess of that permitted the Servicer under this
Agreement. The COLT Indenture Trustee and such successor shall take such action,
consistent with this Agreement, as shall be necessary to effectuate any such
succession. Costs associated with the resignation of the Servicer and the
appointment of a successor Servicer will be distributed by the COLT Indenture
Trustee from amounts in the COLT 2007-SN1 Trust Estate.

     SECTION 5.04 Notification to the Series 2007-SN1 Further Holders and the
Rating Agencies. Upon any termination of, or appointment of a successor to, the
Servicer pursuant to this Article V, the COLT Indenture Trustee shall give
prompt written notice thereof to the Series 2007-SN1 Further Holders and the
Rating Agencies. The COLT Indenture Trustee shall not be deemed to have
knowledge of any Servicer Default unless the COLT Indenture Trustee has received
notice of such event or circumstance from the Servicer in an Officer's
Certificate or from the COLT 2007-SN1 Secured Noteholders or, unless a
Responsible Officer of the COLT Indenture Trustee with knowledge hereof and
familiarity herewith has actual knowledge of such



event or circumstance. If the Servicer obtains knowledge that any Servicer
Default has occurred, the Servicer shall promptly deliver notice of such event
to the COLT Indenture Trustee, which notice shall set forth in reasonable detail
the nature of the facts surrounding such event.

     SECTION 5.05 Waiver of Past Servicer Defaults. The COLT 2007-SN1 Secured
Noteholders may waive any default by the Servicer in the performance of its
obligations hereunder and its consequences. Upon any such waiver of a past
default, such default shall cease to exist, and any Servicer Default arising
therefrom shall be deemed to have been remedied for every purpose of this
Agreement. No such waiver shall extend to any subsequent or other default or
impair any right consequent thereon.

     SECTION 5.06 Repayment of Outstanding Advances. If the identity of the
Servicer shall change, the predecessor Servicer shall be entitled to receive, to
the same extent as if it were still the Servicer hereunder pursuant to Article
III, to the extent of available funds, reimbursement for all Outstanding
Advances that were made by such predecessor Servicer and have not been repaid.

                                   ARTICLE VI
                         OPTIONAL PURCHASE; TERMINATION

     SECTION 6.01 Optional Repurchase of All Series 2007-SN1 Lease Assets. At
any time that the Aggregate ABS Value is less than 2% of the Initial ABS Value,
the Servicer shall have the option to purchase all but not less than all of the
remaining Series 2007-SN1 Lease Assets on any Payment Date following the payment
in full of all obligations under the CARAT 2007-SN1 Notes (such date, the
"Optional Purchase Date"). To exercise such option, the Servicer shall (A)
furnish to the COLT 2007-SN1 Secured Noteholders, the COLT Indenture Trustee,
the COLT Owner Trustee and the VAULT Owner Trustee notice of its intention to
exercise such option and of the Optional Purchase Date (such notice to be
furnished not later than five Business Days prior to such Optional Purchase
Date) and (B) deposit in the COLT Collection Account on such Optional Purchase
Date an amount equal to the Aggregate ABS Value of the Series 2007-SN1 Lease
Assets on the Optional Purchase Date (such amount, the "Optional Purchase
Price"). Upon the making of such deposit in the COLT Collection Account, the
COLT 2007-SN1 Secured Notes shall be deemed satisfied and discharged, and the
COLT 2007-SN1 Certificateholder shall succeed to all interests in and to the
COLT 2007-SN1 Trust Estate (including the Reserve Account).

     SECTION 6.02 Termination of Agreement. This Agreement shall, except as
otherwise provided herein, terminate upon the earliest of: (a) the termination
of COLT pursuant to Article VII of the Declaration of Trust; (b) the discharge
of the Servicer in accordance with the terms hereof; or (c) the mutual written
consent of the parties hereto; provided, however, that this Agreement shall not
be terminated unless all principal and interest on the COLT 2007-SN1 Secured
Notes have been paid in full. Upon termination of this Agreement, the Servicer
shall pay over to COLT, or any other Person entitled thereto, all monies held by
the Servicer on behalf of COLT pursuant to this Agreement.



                                   ARTICLE VII
                            MISCELLANEOUS PROVISIONS

     SECTION 7.01 Amendment.

     (a) This Agreement may be amended by the Servicer, COLT and the COLT
Indenture Trustee without the consent of the COLT 2007-SN1 Certificateholder or
any of the COLT 2007-SN1 Secured Noteholders (i) to cure any ambiguity, (ii) to
correct or supplement any provision in this Agreement that may be defective or
inconsistent with any other provision of this Agreement or in any other COLT
2007-SN1 Basic Document, (iii) to add or supplement any credit enhancement for
the benefit of the COLT 2007-SN1 Secured Noteholders, (iv) to add to the
covenants, restrictions or obligations of the Servicer, the COLT Owner Trustee
or (v) to add, change or eliminate any other provision of this Agreement in any
manner that shall not adversely affect in any material respect the interests of
the COLT 2007-SN1 Secured Noteholders or the COLT 2007-SN1 Certificateholder.

     (b) This Agreement may also be amended from time to time by the Servicer,
COLT and the COLT Indenture Trustee with the consent of the holders of a
majority of the then outstanding principal amount of the COLT 2007-SN1 Secured
Notes and, if any Person other than COLT, LLC or an Affiliate of COLT, LLC holds
any COLT 2007-SN1 Certificates, the consent of the COLT 2007-SN1
Certificateholders whose COLT 2007-SN1 Certificates evidence not less than a
majority of the Voting Interests as of the close of the preceding Distribution
Date, which consent, whether given pursuant to this Section 7.01(b) or pursuant
to any other provision herein, shall be conclusive and binding on such Persons
and on all future holders of COLT 2007-SN1 Certificates and COLT 2007-SN1
Secured Notes for the purpose of adding any provisions to this Agreement or
changing in any manner or eliminating any of the provisions of this Agreement,
or of modifying in any manner the rights of the COLT 2007-SN1 Certificateholder
or COLT 2007-SN1 Secured Noteholders; provided, however, that no such amendment
shall:

          (i) change the due date of any instalment of principal of or interest
on the COLT 2007-SN1 Secured Notes, or reduce the principal amount thereof, the
interest rate applicable thereto, or the Redemption Price with respect thereto,
change any place of payment where, or the coin or currency in which, any COLT
2007-SN1 Secured Note or any distribution thereon is payable, or impair the
right to institute suit as provided in Article V of the COLT Indenture for the
enforcement of the provisions of the COLT Indenture requiring the application of
funds available therefor to the payment of any such amount due on the COLT
2007-SN1 Secured Notes on or after the respective due dates therefor (or, in the
case of redemption, on or after the Redemption Date), or

          (ii) reduce the percentage in this Section 7.01 required to consent to
any action or amendment, without the consent of all of the holders of the COLT
2007-SN1 Secured Notes then outstanding.

     (c) Prior to the execution of any amendment or consent pursuant to Section
7.01(a) or (b), the Servicer shall furnish written notice of the substance of
such amendment or consent to the Rating Agencies.



     (d) Promptly after the execution of any amendment or consent pursuant to
Section 7.01(a) or (b), the COLT Indenture Trustee shall furnish a copy of such
amendment or consent to each COLT 2007-SN1 Secured Noteholder and the COLT
2007-SN1 Certificateholder.

     (e) It shall not be necessary for the consent of the COLT 2007-SN1 Secured
Noteholders or the COLT 2007-SN1 Certificateholder pursuant to Section 7.01(b)
to approve the particular form of any proposed amendment or consent, but it
shall be sufficient if such consent shall approve the substance thereof. The
manner of obtaining such consents (and any other consents of COLT 2007-SN1
Secured Noteholders or the COLT 2007-SN1 Certificateholder provided for in this
Agreement) and of evidencing the authorization of the execution thereof by the
COLT 2007-SN1 Secured Noteholders and the COLT 2007-SN1 Certificateholder shall
be subject to such reasonable requirements as the COLT Indenture Trustee or the
COLT Owner Trustee may prescribe, including the establishment of record dates.

     (f) Prior to the execution of any amendment to this Agreement, the COLT
Indenture Trustee and the COLT Owner Trustee shall be entitled to receive and
conclusively rely upon an Opinion of Counsel stating that the execution of such
amendment is authorized or permitted by this Section 7.01. The COLT Indenture
Trustee and the COLT Owner Trustee, may, but shall not be obligated to, enter
into any such amendment which affects such trustee's own rights, duties or
immunities under this Agreement or otherwise.

     SECTION 7.02 Protection of Title to COLT.

     (a) The Servicer shall maintain accounts and records as to the Series
2007-SN1 Lease Assets accurately and in sufficient detail to permit the reader
thereof to know at any time the status of the Series 2007-SN1 Lease Assets,
including payments and recoveries on (or with respect to) each Series 2007-SN1
Lease and the amounts deposited in the COLT Collection Account, the Reserve
Account, and the Applied Payment Ahead Account and any Payments Ahead held by
the Servicer in respect of each Series 2007-SN1 Lease.

     (b) The Servicer shall maintain its computer systems so that the Servicer's
master computer records (including any back-up archives) that refer to any
Series 2007-SN1 Lease Asset indicate clearly that such Series 2007-SN1 Lease
Asset is owned by COLT. Indication of COLT's ownership of a Series 2007-SN1
Lease Asset shall be deleted from or modified on the Servicer's computer systems
when, and only when, in the case of a Series 2007-SN1 Lease, the Series 2007-SN1
Lease has been paid in full or purchased by the Servicer and, in the case of a
Vehicle, when, and only when, such Vehicle is no longer owned by COLT.

     (c) If at any time the Servicer proposes to sell, grant a security interest
in, or otherwise transfer any interest in automotive leases to any prospective
purchaser, lender or other transferee, the Servicer shall give to such
prospective purchaser, lender or other transferee computer tapes, records or
print-outs (including any restored from back-up archives) that, if they refer in
any manner whatsoever to any Series 2007-SN1 Lease Asset, indicate clearly that
such Series 2007-SN1 Lease Asset is owned by COLT unless such Series 2007-SN1
Lease Asset has been paid in full or repurchased by the Seller or purchased by
the Servicer.



     (d) Neither the Servicer nor COLT shall at any time hold legal title to any
Vehicles. As long as COLT shall own Series 2007-SN1 Lease Assets, legal title to
the related Vehicles shall remain with VAULT, as nominee for COLT.

     (e) To the extent required by law, the Servicer shall cause the COLT
2007-SN1 Secured Notes and the COLT 2007-SN1 Certificate to be registered with
the Commission pursuant to Sections 12(b), 12(g) or 15(h) of the Exchange Act
within the time periods specified in such sections.

     SECTION 7.03 Notices. All demands, notices and communications upon or to
GMAC, the Servicer, the Rating Agencies, COLT, the COLT 2007-SN1 Secured

shall be delivered as specified in Part III of Exhibit A.

     SECTION 7.04 Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK, WITHOUT
REGARD TO THE PRINCIPLES OF CONFLICTS OF LAWS THEREOF OR OF ANY OTHER

OBLIGATIONS LAW), AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES UNDER
THIS AGREEMENT SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

     SECTION 7.05 Severability of Provisions. If any one or more of the
covenants, agreements, provisions or terms of this Agreement is for any reason
whatsoever held invalid, then such covenants, agreements, provisions or terms
shall be deemed severable from the remaining covenants, agreements, provisions
or terms of this Agreement and shall in no way affect the validity or
enforceability of the other provisions of this Agreement.

     SECTION 7.06 Third-Party Beneficiaries. This Agreement shall inure to the
benefit of and be binding upon and enforceable by the parties hereto, the COLT
Owner Trustee, the COLT 2007-SN1 Certificateholder, the COLT 2007-SN1 Secured
Noteholders, the Trust and their respective successors and permitted assigns.
Except as otherwise provided in this Section 7.06, no other Person shall have
any right or obligation hereunder.

     SECTION 7.07 Headings. The headings in this Agreement are included for
convenience only and shall not affect the meaning or interpretation of any
provision of this Agreement.

     SECTION 7.08 Binding Effect. The provisions of this Agreement shall be
binding upon and inure to the benefit of the respective successors and permitted

constitute but one and the same instrument.

     SECTION 7.10 Rights Cumulative. All rights and remedies from time to time
conferred upon or reserved to COLT, the COLT Owner Trustee, and the COLT
Indenture



Trustee on behalf of COLT, the Series 2007-SN1 Further Holders or the Servicer
or to any or all of the foregoing are cumulative, and none is intended to be
exclusive of another. No delay or omission in insisting upon the strict
observance or performance of any provision of this Agreement, or in exercising
any right or remedy, shall be construed as a waiver or relinquishment of such
provision, nor shall it impair such right or remedy. Every right and remedy may
be exercised from time to time and as often as deemed expedient.

     SECTION 7.11 Further Assurances. Each party will do 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
better assure and confirm unto the requesting party its rights, powers and
remedies hereunder.

     SECTION 7.12 No Waiver. No waiver by any party hereto of any one or more
defaults by any other party or parties in the performance of any of the
provisions of this Agreement shall operate or be construed as a waiver of any
future default or defaults, whether of a like or different nature. No failure or
delay on the part of any party in exercising any right, power or remedy
hereunder shall operate as a waiver thereof, nor shall any single or partial
exercise of any such right, power or remedy preclude any other or further
exercise thereof or the exercise of any other right, power or remedy. The
remedies provided for herein are cumulative and are not exclusive of any
remedies that may be available to any party hereto at law, in equity or
otherwise.

     SECTION 7.13 Series Liabilities. It is expressly understood and agreed by
the Servicer, all persons claiming through the Servicer, the COLT 2007-SN1

                         PART II - RULES OF CONSTRUCTION

     (a)  Accounting Terms. As used in this Appendix or the COLT 2007-SN1 Basic
          Documents, accounting terms which are not defined, and accounting
          terms partly defined, herein or therein shall have the respective
          meanings given to them under generally accepted accounting principles.
          To the extent that the definitions of accounting terms in this
          Appendix or the COLT 2007-SN1 Basic Documents are inconsistent with
          the meanings of such terms under generally accepted accounting
          principles, the definitions contained in this Appendix or the COLT
          2007-SN1 Basic Documents will control.

     (b)  "Hereof," etc. The words "hereof," "herein" and "hereunder" and words
          of similar import when used in this Appendix or any COLT 2007-SN1
          Basic Document will refer to this Appendix or such COLT 2007-SN1 Basic
          Document as a whole and not to any particular provision of this
          Appendix or such COLT 2007-SN1 Basic Document; and Section, Schedule
          and Exhibit references contained in this Appendix or any COLT 2007-SN1
          Basic Document are references to Sections, Schedules and Exhibits in
          or to this Appendix or such COLT 2007-SN1 Basic Document unless
          otherwise specified. The word "or" is not exclusive.

     (c)  Reference to Payment Dates. With respect to any Payment Date, the
          "related Collection Period," and the "related Determination Date,"
          will mean the Collection Period and Determination Date, respectively,
          immediately preceding such Payment Date, and the relationships among
          Collection Periods and Determination Dates will be correlative to the
          foregoing relationships.

     (d)  Number and Gender. Each defined term used in this Appendix or the COLT
          2007-SN1 Basic Documents has a comparable meaning when used in its
          plural or singular form. Each gender-specific term used in this
          Appendix or the COLT 2007-SN1 Basic Documents has a comparable meaning
          whether used in a masculine, feminine or gender-neutral form.

     (e)  Including. Whenever the term "including" (whether or not that term is
          followed by the phrase "but not limited to" or "without limitation" or
          words of similar effect) is used in this Appendix or the COLT 2007-SN1
          Basic Documents in connection with a listing of items within a
          particular classification, that listing will be interpreted to be
          illustrative only and will not be interpreted as a limitation on, or
          exclusive listing of, the items within that classification.

     (f)  Capitalized Terms. Capitalized terms, when used in this Appendix,
          shall have the meanings assigned to them in this Appendix, or if not
          defined therein, shall have the meanings assigned to them in the COLT
          Program Definitions attached as Exhibit I to the Declaration of Trust.
