COLT Owner Trustee, on behalf of the Trust and at the direction of the Residual
Certificateholder, will identify and allocate on the Trust's books and records
certain Trust Assets to separate Series Portfolios (as defined in the
Declaration of Trust) and create and issue Certificates to or upon written order
of the Residual Certificateholder representing separate series of equity
beneficial interests in the Trust (each, a "Series Certificate" and together,

                                   ARTICLE X.
                           CREATION OF SERIES 2007-SN1

     Section 10.1 Creation of the Series 2007-SN1 Portfolio and Series 2007-SN1.

     (a) Pursuant to Section 3.2 of the Declaration of Trust, the Residual
Certificateholder hereby directs the COLT Owner Trustee to identify and allocate
or cause to be identified and allocated for all purposes of the Trust on the
books and records of the Trust a separate portfolio of Lease Assets to be
accounted for and held in trust independently from all other assets within the
Owner Trust Estate consisting of the Series 2007-SN1 Lease Assets, which shall
include the Series 2007-SN1 Lease Assets identified on Schedule I hereto and all
other Trust Assets to the extent related thereto, including the Sold Assets
(collectively, the "Series 2007-SN1 Portfolio"). Based upon their identification
and allocation by the Residual Certificateholder pursuant to such Schedule I,
the COLT Owner Trustee hereby identifies and allocates as Series 2007-SN1 Lease
Assets such portfolio of Trust Assets to be held by the Trust, as agent and
nominee of the holder of the COLT 2007-SN1 Certificate, each such Series
2007-SN1 Lease Asset for all purposes on the books and accounts of the Trust as
belonging exclusively to the Series 2007-SN1 Portfolio.


                                       2



     (b) Pursuant to Section 3.2 of the Declaration of Trust, the COLT Owner
Trustee hereby creates a Series, which shall be known as "Series 2007-SN1" and
which shall represent an exclusive and specific divided equity beneficial
ownership interest solely in the Series 2007-SN1 Portfolio and those proceeds or
assets derived from or earned by such Series 2007-SN1 Portfolio.

     (c) The COLT Owner Trustee is hereby authorized to execute and deliver the
COLT 2007-SN1 Basic Documents to which the Trust is a party.

     (d) From time to time after the date hereof, Series 2007-SN1 Lease Assets
may be removed from Series 2007-SN1 in accordance with the COLT Indenture and
the COLT Servicing Agreement. As of any date of determination, the Series
2007-SN1 Portfolio shall include the Lease Assets listed on the Series 2007-SN1
Lease Assets Schedules maintained by the Servicer pursuant to Section 2.19 of
the COLT Servicing Agreement.

     (e) Legal title to all the Series 2007-SN1 Portfolio shall be vested at all
times in the Trust as a separate legal entity except where applicable law in any
jurisdiction requires title to any part of the Series 2007-SN1 Portfolio to be
vested in a trustee or trustees, in which case title shall be deemed to be
transferred to and vested in the COLT Owner Trustee, a co-trustee and/or a
separate trustee or any successor thereto, as the case may be. Any such trustee
shall take such part of the Series 2007-SN1 Portfolio subject to the security
interest therein of the COLT Indenture Trustee or the COLT 2007-SN1 Secured
Noteholders, as applicable, established under the COLT Indenture. Such trustee's
acceptance of its appointment shall constitute acknowledgment of such security
interest and shall constitute a Grant to the COLT Indenture Trustee of a
security interest in all property held by such trustee. Any such trustee shall
prepare and file all such financing statements naming such trustee as debtor
that are necessary or advisable to perfect, make effective or continue the lien
and security interest of the COLT Indenture Trustee.

     Section 10.2 Issuance and Form of Sold Series Certificate.

     (a) Series 2007-SN1 shall be represented by a COLT 2007-SN1 Certificate
which shall represent an exclusive divided equity beneficial ownership interest
in Series 2007-SN1 and the Series 2007-SN1 Portfolio, as further set forth
herein. The COLT 2007-SN1 Certificate shall be substantially in the form of
Exhibit A, with such appropriate insertions, omissions, substitutions and other
variations as are required by this COLT Series Supplement and may have such
letters, numbers or other marks of identification and such legends and
endorsements placed thereon as may, consistently herewith and with the
Declaration of Trust, be directed by the Residual Certificateholder. Any portion
of the COLT 2007-SN1 Certificate may be set forth on the reverse thereof. The
COLT 2007-SN1 Certificate shall be printed, lithographed, typewritten,
mimeographed, photocopied or otherwise produced or may be produced in any other
manner as may, consistently herewith and with the Declaration of Trust, be
determined by the Residual Certificateholder.

     (b) As required by Section 3.2(b) of the Declaration of Trust, the COLT
2007-SN1 Certificate shall contain an express written release and subordination
of any claim by any holder thereof to any proceeds or assets of the COLT Owner
Trustee and to the assets comprising the


                                       3



Owner Trust Estate other than those from time to time included within the Series
2007-SN1 Portfolio and those proceeds or assets derived from or earned by such
Series 2007-SN1 Portfolio.

     Section 10.3 Transferability of Series Interests. Interests in Series
2007-SN1 and the COLT 2007-SN1 Certificate shall be freely transferable, subject
to the restrictions set forth in Sections 3.2(e) and 4.2 of the Declaration of
Trust, applicable law and any contractual provisions limiting such
transferability to which the holder of Series 2007-SN1 and the COLT 2007-SN1
Certificate shall have otherwise agreed. Notwithstanding the foregoing, no
transfer of the COLT 2007-SN1 Certificate or Series 2007-SN1 represented thereby
shall be effective unless and until the COLT 2007-SN1 Certificate shall be
delivered to the COLT Owner Trustee for registration of transfer together with
an assignment attached thereto executed by the registered holder thereof.

     Section 10.4 Pledge of Series 2007-SN1 Portfolio. The parties hereto
acknowledge and agree that the Trust, pursuant to the COLT Indenture, will
pledge those Trust Assets comprising the Series 2007-SN1 Portfolio to the COLT
Indenture Trustee to secure the Trust's obligations under the COLT 2007-SN1
Secured Notes.

any COLT 2007-SN1 Secured Noteholder or the COLT 2007-SN1 Certificateholder;
provided, however, that an Opinion of Counsel shall be furnished to the COLT
Owner Trustee or its designated agent to the effect that (i) such amendment is
authorized or permitted by this Section 11.1(b), (ii) all conditions precedent,
if any, to the execution and delivery of such amendment have been satisfied in
all material respects and (iii) the execution and delivery of such amendment
will not (A) materially adversely affect the federal or any applicable state
income or franchise taxation of any outstanding Secured Notes, Certificates or
of the Trust and (B) cause the Trust to be taxable as a corporation for federal
or any applicable state income or franchise tax purposes.

     (c) The Declaration of Trust may be amended from time to time, with prior

reason not specified in Section 11.1(b) or Section 8.4 of the Declaration of
Trust, by the parties thereto, and this COLT Series Supplement may be amended in

     Section 11.2 Governing Law.

     THIS COLT SERIES SUPPLEMENT SHALL BE CREATED UNDER AND GOVERNED BY AND

Series Supplement and shall in no way affect the validity or enforceability of
the other provisions of this COLT Series Supplement or of the COLT 2007-SN1
Certificate or the rights of the holder thereof. To the extent permitted by law,
the parties hereto waive any provision of law that renders any provision of this
COLT Series Supplement invalid or unenforceable in any respect.

     Section 11.5 Effect of COLT Series Supplement on Declaration of Trust and

                                       5



     Section 11.6 Each Series Separate; Assignees of Series.

     It is intended by the parties hereto that Series 2007-SN1 is a separate
series of the Trust as provided in Section 3806(b)(2) of the Statutory Trust
Act. The debts, liabilities, obligations and expenses incurred, contracted for
or otherwise existing with respect to Series 2007-SN1 or the Series 2007-SN1
Lease Assets shall be enforceable against the Series 2007-SN1 Portfolio only,
and not against any other Trust Assets or the Residual Trust Assets. Except to
the extent required by law or specified in the Declaration of Trust or this COLT
Series Supplement, the Series 2007-SN1 Lease Assets are not subject to claims,
liabilities, expenses or obligations arising from or with respect to the Trust,
the COLT Owner Trustee, the Residual Interest or any other Series in respect of
such claim. No creditor or holder of a claim relating to assets allocated to
Series 2007-SN1 shall be entitled to maintain any action against or recover any
assets allocated to the Residual Interest or any other Series. Notice of this
limitation on interseries liabilities shall be set forth in the certificate of
trust of the Trust (whether originally or by amendment) as filed or to be filed
in the Office of the Secretary of State of the State of Delaware pursuant to the
Statutory Trust Act, and upon the giving of such notice in the certificate of
trust, the statutory provisions of Section 3804 of the Statutory Trust Act
relating to limitations on interseries liabilities (and the statutory effect
under Section 3804 of setting forth such notice in the certificate of trust)
shall become applicable to the Trust and each Series and the Residual Interest.
Any purchaser, assignee or pledgee of an interest in Series 2007-SN1 or the COLT
2007-SN1 Certificate must, prior to or contemporaneously with the grant of any
such assignment, pledge or security interest, (i) give to the Trust a no
petition covenant substantially similar to that set forth in Section 8.8 of the
Declaration of Trust, and (ii) execute an agreement for the benefit of each
holder, assignee or pledgee from time to time of the Residual Interest or
Residual Certificate and any other Series or Series Certificate, to release all
claims to the assets of the Trust allocated to the Residual Interest and each
other Series Portfolio and in the event that such release is not given effect,
to fully subordinate all claims it may be deemed to have against the assets of
the Trust allocated to the Residual Interest and each other Series Portfolio. In
the event of a sale or assignment of a Series, such purchaser or assignee shall
be a beneficiary of the Trust in the manner and to the extent set forth in the
Series Certificate so acquired and in the applicable COLT Series Supplement.

     Section 11.7 Nonpetition; Release of Claims.

     Notwithstanding any other provision of the Declaration of Trust, this COLT
Series Supplement, any other Basic Document or any other COLT 2007-SN1 Basic
Document and notwithstanding any prior termination of the Declaration of Trust
or this COLT Series Supplement, each Certificateholder and the COLT Owner
Trustee shall not, prior to the date which is one year and one day after the
termination of the Declaration of Trust with respect to the Trust, acquiesce,
petition or otherwise invoke or cause the Trust to invoke the process of any
Governmental Authority for the purpose of commencing or sustaining a case
against the Trust under any federal or state bankruptcy, insolvency or similar
law or appointing a receiver, liquidator, assignee, trustee, custodian,
sequestrator or other similar official of the Trust or any substantial part of
its property, or ordering the winding up or liquidation of the affairs of the
Trust.


                                       6



     Section 11.8 Tax Matters.

     Each of the Residual Certificateholder and the COLT Owner Trustee agree
that for federal and state income tax purposes it shall not treat this COLT
Series Supplement as creating or constituting a trust, partnership, association
taxable as a corporation or any other type of separate entity (and will report
for such purposes in a consistent manner therewith). Instead, it is the
intention of the parties hereto that, solely for purposes of federal income
taxes, state and local income and franchise taxes, Michigan single business tax
and any other taxes imposed upon, measured by or based upon gross or net income,
the Trust shall be treated (i) when the Certificates are legally or beneficially
owned by two or more Persons, as a partnership and (ii) when the Certificates
are legally or beneficially owned by one Person, as a disregarded entity for
purposes of Treasury Regulation 301.7701-3, and in each case, that the
provisions of this COLT Series Supplement shall be construed in accordance with
such intent. Each such party further agrees that the Trust is acting as holder
of record title to the 2007-SN1 Series Portfolio, other than the Vehicles
contained therein, solely for the benefit of, and as agent and nominee of, the
holder of the COLT 2007-SN1 Certificate, and shall not hold itself out or act in
a manner inconsistent with it acting merely as agent and nominee.

     Section 11.9 Information to be Provided by the COLT Owner Trustee.

     (a) The COLT Owner Trustee agrees to cooperate in good faith with any
reasonable request by the Servicer for information regarding the COLT Owner
Trustee which is required in order to enable the Servicer to comply with the
provisions of Items 1117 and 1119 of Regulation AB as it relates to the COLT
Owner Trustee or to the COLT Owner Trustee's obligations under this Agreement.

     (b) Except to the extent disclosed by the COLT Owner Trustee in subsection
(c) or (d) below, the COLT Owner Trustee shall be deemed to have represented to
the Servicer on the first day of each Collection Period with respect to the
prior Collection Period that to the best of its knowledge there were no legal or
governmental proceedings pending (or known to be contemplated) against Deutsche
Bank Trust Company Delaware or any property of Deutsche Bank Trust Company
Delaware that would be material to any COLT 2007-SN1 Secured Noteholder or, to
the extent that the COLT 2007-SN1 Certificates are registered under the
Securities Act for public sale, any holder of such COLT 2007-SN1 Certificates.

     (c) The COLT Owner Trustee shall, as promptly as practicable following
notice to or discovery by the COLT Owner Trustee of any changes to any
information regarding the COLT Owner Trustee as is required for the purpose of
compliance with Item 1117 of Regulation AB, provide to the Servicer, in writing,
such updated information.

     (d) The COLT Owner Trustee shall deliver to the Servicer on or before March
15 of each year, beginning with March 15, 2008, a report of a representative of
the COLT Owner Trustee with respect to the immediately preceding calendar year
certifying, on behalf of the COLT Owner Trustee, that except to the extent
otherwise disclosed in writing to the Servicer, to the best of his or her
knowledge there were no legal or governmental proceedings pending (or known to
be contemplated) against Deutsche Bank Trust Company Delaware or any property of
Deutsche Bank Trust Company Delaware that would be material to any COLT 2007-SN1


                                       7



Secured Noteholder or, to the extent that the COLT 2007-SN1 Certificates are
registered under the Securities Act for public sale, any holder of such COLT
2007-SN1 Certificates.

     (e) The COLT Owner Trustee shall deliver to the Servicer on or before March
15 of each year, beginning with March 15, 2008, a report of a representative of
the COLT Owner Trustee with respect to the immediately preceding calendar year
providing to the Servicer such information regarding the COLT Owner Trustee as
is required for the purpose of compliance with Item 1119 of Regulation AB. Such
information shall include, at a minimum, a description of any affiliation
between the COLT Owner Trustee and any of the following parties to this
securitization transaction, as such parties are identified to the COLT Owner
Trustee by the Servicer in writing in advance of this securitization
transaction:

          (i)  CARI;

          (ii) GMAC;

          (iii) the Trust;

          (iv) the Servicer;

          (v)  the COLT Indenture Trustee;

          (vi) the Swap Counterparty; and

          (vii) any other material transaction party.

In connection with the parties listed in clauses (i) through (vii) above, the
COLT Owner Trustee shall include a description of whether there is, and if so,
the general character of, any business relationship, agreement, arrangement,
transaction or understanding that is entered into outside the ordinary course of
business or is on terms other than would be obtained in an arm's length
transaction with an unrelated third party, apart from this securitization
transaction, that currently exists or that existed during the past two years and
that is material to an investor's understanding of the asset backed securities

     THIS CERTIFIES THAT _______________, a _____________, is the registered
owner of a nonassessable, fully-paid, undivided equity beneficial interest in
the Series 2007-SN1 Lease Assets of Central Originating Lease Trust, a Delaware
statutory trust ("COLT" or the "Trust") of which Central Originating Lease, LLC,
a Delaware limited liability company, is the residual certificateholder ("COLT,
LLC" or, in its capacity as residual certificateholder thereunder, and, together
with any successor or assign in such capacity, the "Residual
Certificateholder"), and


                                  Exhibit A-1



Deutsche Bank Trust Company Delaware, as COLT Owner Trustee (in such capacity,
together with any successor or permitted assign, the "COLT Owner Trustee"). The
Trust exists pursuant to the Declaration of Trust, dated as of December 13, 2006
(as it may be amended from time to time, the "Declaration of Trust"), by the
COLT Owner Trustee and acknowledged, accepted and agreed to by COLT, LLC, as
Residual Certificateholder, as supplemented for purposes hereof by that certain
COLT 2007-SN1 Supplement to Declaration of Trust, dated as of June 7, 2007 (as
it may be amended from time to time, the "COLT 2007-SN1 Supplement to the
Declaration"), between COLT, LLC, as Residual Certificateholder, and the COLT
Owner Trustee. A summary of certain of the pertinent portions of the Declaration
of Trust is set forth below. To the extent not otherwise defined herein,
capitalized terms used herein have the meanings set forth in Part I of Exhibit I
to the Declaration of Trust.

     This Certificate is the duly authorized certificate issued under the
Declaration of Trust and the COLT 2007-SN1 Supplement to the Declaration, and is
designated as "Central Originating Lease Trust 2007-SN1 Certificate" (the "COLT
2007-SN1 Certificate"). This COLT 2007-SN1 Certificate is issued under and is
subject to the terms, provisions and conditions of the Declaration of Trust
(including the COLT 2007-SN1 Supplement to the Declaration), the terms of which
are incorporated herein by reference and made a part hereof, to which
Declaration of Trust the holder of this COLT 2007-SN1 Certificate by virtue of
the acceptance hereof assents and by which such holder is bound. There has also
been issued under the Declaration of Trust a Residual Certificate (the "Residual
Certificate"), and various additional series of Certificates representing Series
of equity beneficial interests (each such additional Certificate, a "Series
Certificate" and, together with the Residual Certificate, the "Certificates").
The Residual Certificate evidences an exclusive, undivided beneficial interest
in the Trust Assets other than Trust Assets allocated to a particular Series
(each as defined in the Declaration of Trust), and each series of Series
Certificates, taken together, will evidence an exclusive undivided beneficial
interest in a separate Series Portfolio (as defined below).

     The Declaration of Trust provides that, from time to time, certain of the
Trust Assets will be identified and allocated on the records of the Trust into
one or more separate portfolios of Trust Assets (each such portfolio, a "Series
Portfolio"). The equity beneficial interest in each such Series Portfolio will
constitute a separate series of equity beneficial interest" (a "Series") in the
Trust. Pursuant to the COLT 2007-SN1 Supplement to the Declaration of Trust,
various Trust Assets (the "Series 2007-SN1 Lease Assets") were identified and
allocated on the records of the Trust into a separate Series Portfolio (the
"Series 2007-SN1 Portfolio"), and the equity beneficial interest in the Series
2007-SN1 Portfolio was designated as a separate Series known as the "Series
2007-SN1." The rights of the holder of this Certificate to the proceeds of the
Series 2007-SN1 Lease Assets are and will be further set forth in the
Declaration of Trust and the COLT 2007-SN1 Supplement to the Declaration of
Trust.

     This Certificate does not represent an obligation of, or an interest in
GMAC LLC, COLT, LLC or the COLT Owner Trustee, or any of their respective
Affiliates (other than the Trust). This Certificate is limited in right of
payment to certain collections and recoveries respecting the Series 2007-SN1
Lease Assets allocated to the Series 2007-SN1 Portfolio, all to the extent and
as more specifically set forth in the Declaration of Trust. A copy of the
Declaration of Trust may be examined during normal business hours at the
Corporate Trust Office of the COLT Owner


                                  Exhibit A-2



Trustee, and at such other places, if any, designated by the COLT Owner Trustee,
by the holder hereof upon request.

     By accepting this Certificate, the holder hereof releases (or fully
subordinates, but only to the extent such release is not given effect) any claim
in respect of this Certificate to any proceeds or assets of the Trust other than
those from time to time included within the Series 2007-SN1 Portfolio as Series
2007-SN1 Lease Assets and those proceeds or assets derived from or earned by
such Series 2007-SN1 Lease Assets.

     The COLT 2007-SN1 Supplement to the Declaration permits, with certain
exceptions provided therein, the amendment of the Declaration of Trust and the
COLT 2007-SN1 Supplement to the Declaration, and the modification of the rights
and obligations of the parties thereto with respect to the Series 2007-SN1 Lease
Assets, the Series 2007-SN1 Portfolio and Series 2007-SN1 and the rights of the
holder of the COLT 2007-SN1 Certificate at any time by the holder of the COLT
2007-SN1 Certificate, the Residual Certificateholder and the COLT Owner Trustee.
If approval of any holder of this Certificate is required, any such consent
shall be conclusive and binding on such holder and on all future holders hereof
and of any Certificate issued upon the permitted transfer hereof or in exchange
herefor or in lieu hereof whether or not notation of such consent is made upon
this Certificate. The COLT 2007-SN1 Supplement to the Declaration also permits
the amendment thereof, in certain circumstances, without the consent of any
Person other than the Residual Certificateholder and the COLT Owner Trustee.

     The holder of this Certificate (and each pledgee of this Certificate, by
virtue of its acceptance of such pledge) covenants and agrees that it shall not,
prior to the date which is one year and one day after the termination of the
Declaration of Trust, acquiesce, petition or otherwise invoke or cause the Trust
to invoke the process of any Governmental Authority for the purpose of
commencing or sustaining a case against the Trust under any federal or state
bankruptcy, insolvency or similar law or appointing a receiver, liquidator,
assignee, trustee, custodian, sequestrator or other similar official of the
Trust or any substantial part of its property, or ordering the winding up or
liquidation of the affairs of the Trust.

     No bankruptcy, reorganization arrangement, insolvency or liquidation
proceeding or other proceedings under any federal or state bankruptcy,
insolvency or similar law shall be instituted by the Trust without the consent
of the COLT Owner Trustee. The COLT Owner Trustee shall not so consent unless
directed to do so by all of the Certificateholders.

     Prior to due presentation of this Certificate for registration of a
permitted transfer, the COLT Owner Trustee, the certificate registrar and any of
their respective agents may treat the person or entity in whose name this
Certificate is registered as the owner hereof for the purpose of receiving
distributions and for all other purposes, and, except as provided for in the
Declaration of Trust, neither the COLT Owner Trustee, the certificate registrar
nor any such agent shall be affected by any notice to the contrary.

     Unless this Certificate shall have been executed and authenticated by the
COLT Owner Trustee or Deutsche Bank Trust Company Americas, as the COLT Owner
Trustee's authenticating agent, by manual signature, this Certificate shall not
entitle the holder hereof to any benefit under the Declaration of Trust or be
valid for any purpose.


                                  Exhibit A-3



     No interest in Series 2007-SN1, this Certificate or the Series 2007-SN1
Portfolio shall be transferred, assigned, sold or conveyed if, as the result of
such transfer, assignment, sale or conveyance, the Trust would become a publicly
traded partnership.

     THIS CERTIFICATE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
INTERNAL LAWS OF THE STATE OF DELAWARE, WITHOUT REGARD TO THE PRINCIPLES OF
CONFLICTS OF LAW THEREOF OR OF ANY OTHER JURISDICTION, AND THE OBLIGATIONS,
RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE
WITH SUCH LAWS.

                  [Remainder of page intentionally left blank.]
