dated as of March 17, 2003, as amended and restated by the Third Amended and

     (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 200_-_" and

ownership interest solely in the Series 200_-_ Portfolio and those proceeds or
assets derived from or earned by such Series 200_-_ Portfolio.

     (c) The COLT Owner Trustee is hereby authorized to execute and deliver the

Assets Schedule maintained by the Servicer pursuant to Section 2.19 of the COLT

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 200_-_ Portfolio subject to the security
interest therein of the COLT Indenture Trustee or the COLT 200_-_ 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 200_-_ shall be represented by a COLT 200_-_ Certificate which

COLT 200_-_ 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 200_-_
Certificate may be set forth on the reverse thereof. The COLT 200_-_ 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
200_-_ 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 Owner Trust Estate other than those
from time to time included within the Series 200_-_ Portfolio and those proceeds
or assets derived from or earned by such Series 200_-_ Portfolio.

200_-_ and the COLT 200_-_ 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 200_-_ and the COLT 200_-_
Certificate shall have otherwise agreed. Notwithstanding the foregoing, no

     (c) With prior notice to each Rating Agency, the Declaration of Trust may

     Section 11.4 Severability of Provisions.

     If any one or more of the covenants, agreements, provisions or terms of
this COLT Series Supplement shall be 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 COLT
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 200_-_
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
Basic Documents.

     (a) Except as otherwise specifically provided herein: (i) the parties shall
continue to be bound by all provisions of the Declaration of Trust; and (ii) the
provisions set forth herein shall operate either as additions to or
modifications of the obligations of the parties under the Declaration of Trust,
as the context may require. In the event of any conflict between the provisions
of this COLT Series Supplement and the Declaration of Trust with respect to
Series 200_-_, the provisions of this COLT Series Supplement shall prevail.

     (b) For purposes of determining the parties' obligations under this COLT
Series Supplement with respect to Series 200_-_, general references in the
Declaration of Trust to: (i) the Series Portfolio shall be deemed to refer more
specifically to the Series 200_-_ Portfolio and (ii) the COLT Series Supplement
shall be deemed to refer more specifically to this COLT Series Supplement.

     Section 11.6 Each Series Separate; Assignees of Series.

     It is intended by the parties hereto that Series 200_-_ 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 200_-_ or the Series 200_-_ Lease
Assets shall be enforceable against the Series 200_-_ 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 200_-_ 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 200_-_ 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 200_-_ or the COLT
200_-_ Certificate must, prior to or contemporaneously


                                        7

<PAGE>

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 200_-_ 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.

     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

                                   Exhibit A-1

<PAGE>

[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 Third Amended and Restated Declaration of Trust,
dated as of March 25, 2004 (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, and General Motors
Acceptance Corporation, as supplemented for purposes hereof by that certain
Series 200_-_ Supplement to Third Amended and Restated Declaration of Trust
dated as of _____, 200_ (as it may be amended from time to time, the "Series
200_-_ 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 Series 200_-_ Supplement to the Declaration, and is
designated as "Central Originating Lease Trust 200_-_ Certificate" (the "COLT
200_-_ Certificate"). This COLT 200_-_ Certificate is issued under and is
subject to the terms, provisions and conditions of the Declaration of Trust
(including the Series 200_-_ 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 200_-_ Certificate by virtue of the
acceptance hereof assents and by which such holder is bound. There has also been
issued a Residual Certificate (the "Residual Certificate") and a Series 2004-SNA
Certificate (the "Series 2004-SNA Certificate") and there may also be issued
under the Declaration of Trust various additional series of Certificates
representing Series of equity beneficial interests (each of the Series 2004-SNA
Certificate and this COLT 200_-_ Certificate, a "Series Certificate" and,
together with the Residual Certificate, the "Certificates"). The Residual
Certificate evidences an exclusive, divided 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 divided 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 Series 200_-_ Supplement to the Declaration, various
Trust Assets (the "Series 200_-_ Lease Assets") were identified and allocated on
the records of the Trust into a separate Series Portfolio (the "Series 200_-_
Portfolio"), and the equity beneficial interest in the Series 200_-_ Portfolio
was designated as a separate Series known as the "Series 200_-_." The rights of
the holder of this Certificate to the proceeds of the Series 200_-_ Lease Assets
are and will be further set forth in the Declaration of Trust and the Series
200_-_ Supplement to the Declaration.

     This Certificate does not represent an obligation of, or an interest in
General Motors Acceptance Corporation, 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 200_-_ Lease Assets allocated to the Series 200_-_ Portfolio, all to the
extent and as more specifically set forth in the Declaration of Trust.

<PAGE>

A copy of the Declaration of Trust may be examined during normal business hours
at the Corporate Trust Office of the COLT Owner 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 200_-_ Portfolio as Series
200_-_ Lease Assets and those proceeds or assets derived from or earned by such
Series 200_-_ Lease Assets.

exceptions provided therein, the amendment of the Declaration of Trust and the
Series 200_-_ Supplement to the Declaration, and the modification of the rights
and obligations of the parties thereto with respect to the Series 200_-_ Lease
Assets, the Series 200_-_ Portfolio and Series 200_-_ and the rights of the
holder of the COLT 200_-_ Certificate at any time by the holder of the COLT
200_-_ 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 Series 200_-_ 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.

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

such transfer, assignment, sale or conveyance, the Trust would become a publicly
traded partnership.

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.
