     Section 2.6 Declaration of Trust. The CARAT Owner Trustee hereby declares
that it shall hold the CARAT Owner Trust Estate (in the name of the Trust and

in accordance with, Section 2.8) in trust upon and subject to the conditions set
forth herein for the use and benefit of the CARAT 2007-SN1 Certificateholders,
subject to the obligations of the Trust under the CARAT Basic Documents. It is
the intention of the parties hereto that the Trust constitute a statutory trust
under the Statutory Trust Act, that this Agreement constitute the governing
instrument of such statutory trust and that the CARAT 2007-SN1 Certificates
represent the beneficial interests therein. The rights of the CARAT 2007-SN1
Certificateholders shall be determined as set forth herein and in the Statutory
Trust Act and the relationship between the parties hereto created by this

which case title shall be deemed to be transferred to and vested in the CARAT
Owner Trustee, a co-trustee and/or a separate trustee, as the case may be. Any
such trustee shall take such part of the CARAT Owner Trust Estate subject to the
security interest of the CARAT Indenture Trustee therein established under the
CARAT Indenture. Such trustee's acceptance of its appointment shall constitute
acknowledgment of such security interest and shall constitute a Grant to the
CARAT 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 of the CARAT Indenture Trustee.

          (c) The CARAT 2007-SN1 Certificates shall be issued in
fully-registered form. The terms of the CARAT 2007-SN1 Certificates set forth in
Exhibit A shall form part of this Agreement.

     Section 3.3 Execution, Authentication and Delivery. Concurrently with the
sale of the COLT 2007-SN1 Secured Notes to the Trust pursuant to the Trust Sale
and Administration Agreement, the CARAT Owner Trustee shall cause a single CARAT
2007-SN1 Certificate representing the entire beneficial interest in the Trust to
be executed on behalf of the Trust, authenticated and delivered to or upon the
written order of the Seller, signed by its chairman of the board, its president
or any vice president, without further corporate or limited liability company
action by the Seller. Such CARAT 2007-SN1 Certificate shall be issued to and
held by the Seller, as the initial CARAT 2007-SN1 Certificateholder. No CARAT
2007-SN1 Certificate shall entitle its holder to any benefit under this
Agreement, or shall be valid for any purpose, unless there shall appear on such
CARAT 2007-SN1 Certificate a certificate of authentication substantially in the
form set forth in Exhibit A, executed by the CARAT Owner Trustee or Deutsche
Bank Trust Company Americas, as the CARAT Owner Trustee's authenticating agent,
by manual signature. Such authentication shall constitute conclusive evidence
that such CARAT 2007-SN1 Certificate shall have been duly authenticated and
delivered hereunder. All CARAT 2007-SN1 Certificates shall be dated the date of
their authentication.

     Section 3.4 Registration; Registration of Transfer and Exchange of CARAT
2007-SN1 Certificates.

          (a) The Certificate Registrar shall keep or cause to be kept, at the
office or agency maintained pursuant to Section 3.8, a Certificate Register in
which, subject to such reasonable regulations as it may prescribe, the CARAT
Owner Trustee shall provide for the registration of CARAT 2007-SN1 Certificates
and of transfers and exchanges of CARAT 2007-SN1 Certificates as provided
herein. Deutsche Bank Trust Company Americas shall be the initial Certificate
Registrar. Upon any resignation of a Certificate Registrar, the CARAT Owner
Trustee shall promptly appoint a successor or, if it elects not to make such an
appointment, assume the duties of Certificate Registrar.

          (b) A CARAT 2007-SN1 Certificateholder may at any time, without
consent of the Noteholders, sell, transfer, convey or assign in any manner its
rights to and interests in the CARAT 2007-SN1 Certificates, but only if: (i)
such action shall not result in a reduction or withdrawal of the rating of any
class of CARAT 2007-SN1 Notes, (ii) the CARAT 2007-SN1 Certificateholder shall
provide to the CARAT Owner Trustee and the CARAT Indenture Trustee an Opinion of
Counsel (which counsel is independent from the Seller and the Issuer) that such
action shall not cause the Trust to be treated as an association (or publicly
traded partnership) taxable as a corporation for federal income tax purposes,
(iii) such transferee or assignee shall agree to take positions for tax purposes
consistent with the tax positions set forth in Section 2.11 of this Agreement
agreed to be taken by the CARAT 2007-SN1 Certificateholder, and (iv) the
conditions set forth in Section 9.14 shall have been satisfied. In addition, no
transfer of a CARAT 2007-SN1 Certificate shall be registered unless the
transferee shall have provided to the CARAT Owner Trustee and the Certificate
Registrar an Opinion of Counsel from independent counsel that in connection with
such transfer no registration of the CARAT 2007-SN1 Certificates is required
under the Securities Act or applicable State securities law or that such


                                       6



transfer is otherwise being made in accordance with all applicable federal and
State securities laws. In connection with any transfer of less than all of the
interests in the CARAT 2007-SN1 Certificates, the transferor and the transferee
shall specify the respective interests in the CARAT 2007-SN1 Certificates to be
held by transferor and transferee, which interests may be determined by a
formula or on any other basis agreed by transferor and transferee. If agreed by
transferor and transferee, different interests may be used for distributions of
proceeds and for purposes of voting the CARAT 2007-SN1 Certificates, and the
transferor shall notify the CARAT Owner Trustee of any such agreement in
connection with such transfer.

          (c) If the Seller is no longer the sole CARAT 2007-SN1
Certificateholder, the Trust Administrator shall promptly prepare amendments
(subject to the provisions regarding amendments in the applicable CARAT Basic
Documents) to the CARAT Basic Documents to the extent necessary to reflect the
issuance of book-entry certificates, the establishment of the Certificate
Distribution Account and the making of distributions to the CARAT 2007-SN1
Certificateholders and such other matters as shall be agreed between the Seller
and the CARAT Owner Trustee. The expense of the foregoing amendments shall be
paid by the Trust Administrator.

          (d) Upon surrender for registration of transfer of any CARAT 2007-SN1
Certificate at the office or agency maintained pursuant to Section 3.8, the
CARAT Owner Trustee shall execute on behalf of the Trust, authenticate and
deliver (or shall cause Deutsche Bank Trust Company Americas as its
authenticating agent to authenticate and deliver), in the name of the designated
transferee or transferees, one or more new CARAT 2007-SN1 Certificates of a like
aggregate percentage interest dated the date of authentication by the CARAT
Owner Trustee or any authenticating agent.

          (e) At the option of a Holder, CARAT 2007-SN1 Certificates may be
exchanged for other CARAT 2007-SN1 Certificates of a like aggregate percentage
interest upon surrender of the CARAT 2007-SN1 Certificates to be exchanged at
the Corporate Trust Office maintained pursuant to Section 3.8. Whenever any
CARAT 2007-SN1 Certificates are so surrendered for exchange, the CARAT Owner
Trustee shall execute on behalf of the Trust, authenticate and deliver (or shall
cause Deutsche Bank Trust Company Americas as its authenticating agent to
authenticate and deliver) one or more CARAT 2007-SN1 Certificates dated the date
of authentication by the CARAT Owner Trustee or any authenticating agent. Such
CARAT 2007-SN1 Certificates shall be delivered to the Holder making the
exchange.

          (f) Every CARAT 2007-SN1 Certificate presented or surrendered for
registration of transfer or exchange shall be accompanied by a written
instrument of transfer in form satisfactory to the CARAT Owner Trustee and the
Certificate Registrar duly executed by the Holder or his attorney duly
authorized in writing and such other documents and instruments as may be
required by Section 3.4(b). Each CARAT 2007-SN1 Certificate surrendered for
registration of transfer or exchange shall be canceled and subsequently
destroyed or otherwise disposed of by the CARAT Owner Trustee or Certificate
Registrar in accordance with its customary practice.

          (g) The CARAT Owner Trustee or the Certificate Registrar may require
payment of a sum sufficient to cover any tax or governmental charge that may be
imposed and


                                       7



any other expenses of the CARAT Owner Trustee in connection with any transfer or
exchange of CARAT 2007-SN1 Certificates.

          (h) Each purchaser and transferee of a CARAT 2007-SN1 Certificate (or
any interest therein) shall be deemed to represent and warrant that it is not
(and for so long as it holds such Certificate or interest therein will not be),
and it is not acting on behalf of (and for so long as it holds such Certificate
or interest therein will not be acting on behalf of) a Benefit Plan. If
requested to do so by the Seller, each purchaser and transferee of a CARAT
2007-SN1 Certificate shall execute and deliver to the CARAT Owner Trustee an
undertaking letter in form and substance satisfactory to the CARAT Indenture
Trustee and the Seller.

          (i) Notwithstanding any other provision of this Agreement, no sale,
transfer, assignment or conveyance of a CARAT 2007-SN1 Certificate (or any
interest therein within the meaning of Treasury Regulation Section
1.7704-1(a)(2)) shall be permitted, and any such purported sale, transfer,
assignment or conveyance shall be void ab initio and of no effect, unless the
transferee first shall have provided to the CARAT Owner Trustee, the CARAT
Indenture Trustee and the Trust Administrator an opinion of independent tax
counsel concluding that (i) the sale, transfer, assignment or conveyance will
not be effected through an "established securities market" or "secondary market
(or the substantial equivalent thereof)" within the meaning of Section 7704(b)
of the Code, and (ii) after such sale, transfer, assignment or conveyance, there
will be no more than 50 Holders of the CARAT 2007-SN1 Certificates. For purposes
of making the foregoing determination, each person directly owning an interest
in a CARAT 2007-SN1 Certificate shall be treated as a Holder and each person
indirectly owning an interest in a CARAT 2007-SN1 Certificate through a
partnership (including any entity treated as a partnership for federal income
tax purposes), a grantor trust or an S corporation (each such entity, a
"flow-through entity") shall be treated as a Holder unless the Trust
Administrator determines in its sole and absolute discretion, after consulting
with qualified tax counsel experienced in such matters, that less than
substantially all of the value of the beneficial owner's interest in the
flow-through entity is attributable to the flow-through entity's interest
(direct or indirect) in the CARAT 2007-SN1 Certificate. In no event shall the
CARAT Owner Trustee be responsible for calculating the number of beneficial
owners of the CARAT 2007-SN1 Certificates.

     Section 3.5 Mutilated, Destroyed, Lost or Stolen CARAT 2007-SN1
Certificates.

          (a) If (i) any mutilated CARAT 2007-SN1 Certificate is surrendered to
the Certificate Registrar, or the Certificate Registrar receives evidence to its
satisfaction of the destruction, loss or theft of any CARAT 2007-SN1
Certificate, and (ii) there is delivered to the Certificate Registrar, the CARAT
Owner Trustee and the Trust such security or indemnity as may be required by
them to hold each of them harmless, then, in the absence of notice to the
Certificate Registrar or the CARAT Owner Trustee that such CARAT 2007-SN1
Certificate has been acquired by a protected purchaser, the CARAT Owner Trustee
shall execute on behalf of the Trust and the CARAT Owner Trustee shall
authenticate and deliver (or shall cause Deutsche Bank Trust Company Americas as
its authenticating agent to authenticate and deliver), in exchange for or in
lieu of any such mutilated, destroyed, lost or stolen CARAT 2007-SN1
Certificate, a replacement CARAT 2007-SN1 Certificate of a like aggregate
percentage interest; provided, however, that if any such destroyed, lost or
stolen CARAT 2007-SN1 Certificate, but


                                       8



not a mutilated CARAT 2007-SN1 Certificate, shall have become or within seven
days shall be due and payable, then instead of issuing a replacement CARAT
2007-SN1 Certificate the CARAT Owner Trustee may pay such destroyed, lost or
stolen CARAT 2007-SN1 Certificate when so due or payable.

          (b) If, after the delivery of a replacement CARAT 2007-SN1 Certificate
or payment in respect of a destroyed, lost or stolen CARAT 2007-SN1 Certificate
pursuant to Section 3.5(a), a Protected Purchaser of the original CARAT 2007-SN1
Certificate in lieu of which such replacement CARAT 2007-SN1 Certificate was
issued presents for payment such original CARAT 2007-SN1 Certificate, the CARAT
Owner Trustee shall be entitled to recover such replacement CARAT 2007-SN1
Certificate (and any distributions or payments made with respect thereto) or
such payment from the Person to whom it was delivered or any Person taking such
replacement CARAT 2007-SN1 Certificate from such Person to whom such replacement
CARAT 2007-SN1 Certificate was delivered or any assignee of such Person, except
a Protected Purchaser, and shall be entitled to recover upon the security or
indemnity provided therefor to the extent of any loss, damage, cost or expense
incurred by the CARAT Owner Trustee in connection therewith.

          (c) In connection with the issuance of any replacement CARAT 2007-SN1
Certificate under this Section 3.5, the CARAT Owner Trustee may require the
payment by the Holder of such CARAT 2007-SN1 Certificate of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto and any other reasonable expenses (including the fees and expenses of
the CARAT Owner Trustee and the Certificate Registrar) connected therewith.

          (d) Any duplicate CARAT 2007-SN1 Certificate issued pursuant to this
Section 3.5 in replacement of any mutilated, destroyed, lost or stolen CARAT
2007-SN1 Certificate shall constitute an original additional beneficial interest
in the Trust, whether or not the mutilated, destroyed, lost or stolen CARAT
2007-SN1 Certificate shall be found at any time or be enforced by anyone, and
shall be entitled to all the benefits of this Agreement equally and
proportionately with any and all other CARAT 2007-SN1 Certificates duly issued
hereunder.

          (e) The provisions of this Section 3.5 are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, destroyed, lost or stolen CARAT
2007-SN1 Certificates.

     Section 3.6 Persons Deemed CARAT 2007-SN1 Certificateholders. Prior to due
presentation of a CARAT 2007-SN1 Certificate for registration of transfer, the
CARAT Owner Trustee or the Certificate Registrar may treat the Person in whose
name any CARAT 2007-SN1 Certificate shall be registered in the Certificate
Register as the CARAT 2007-SN1 Certificateholder of such CARAT 2007-SN1
Certificate for the purpose of receiving distributions pursuant to Article V and
for all other purposes whatsoever, and neither the CARAT Owner Trustee nor the
Certificate Registrar shall be affected by any notice to the contrary.

     Section 3.7 Access to List of CARAT 2007-SN1 Certificateholders' Names and
Addresses. The CARAT Owner Trustee shall furnish or cause to be furnished to the
Trust


                                       9



Administrator and the Seller, within 15 days after receipt by the CARAT Owner
Trustee of a request therefor from the Trust Administrator or the Seller, in
writing, a list of the names and addresses of the CARAT 2007-SN1
Certificateholders as of the most recent Record Date. Each Holder, by receiving
and holding a CARAT 2007-SN1 Certificate, shall be deemed to have agreed not to
hold any of the Trust Administrator, the Seller or the CARAT Owner Trustee
accountable by reason of the disclosure of its name and address, regardless of
the source from which such information was derived.

     Section 3.8 Maintenance of Corporate Trust Office. The CARAT Owner Trustee
shall maintain in the Borough of Manhattan, The City of New York, an office or
offices or agency or agencies where CARAT 2007-SN1 Certificates may be
surrendered for registration of transfer or exchange and where notices and
demands to or upon the CARAT Owner Trustee in respect of the CARAT 2007-SN1
Certificates and the CARAT Basic Documents may be served. The CARAT Owner
Trustee initially designates the offices of Deutsche Bank Trust Company
Americas, 60 Wall Street, New York, NY 10005, as its principal office for such
purposes. The CARAT Owner Trustee shall give prompt written notice to the
Seller, to the Trust Administrator, and to the CARAT 2007-SN1 Certificateholders
of any change in the location of the Certificate Register or any such office or
agency.

     Section 3.9 Appointment of Paying Agent. Except as otherwise provided in
Section 5.2, the Paying Agent shall make distributions to CARAT 2007-SN1
Certificateholders from the Certificate Distribution Account pursuant to Section
5.2 and shall report the amounts of such distributions to the CARAT Owner
Trustee and the Trust Administrator; provided, however, that no such reports
shall be required so long as the Seller is the sole CARAT 2007-SN1
Certificateholder. Any Paying Agent shall have the revocable power to withdraw
funds from the Certificate Distribution Account for the purpose of making the
distributions referred to above. The CARAT Owner Trustee may revoke such power
and remove the Paying Agent if the CARAT Owner Trustee determines in its sole
discretion that the Paying Agent shall have failed to perform its obligations
under this Agreement in any material respect. The Paying Agent shall initially
be Deutsche Bank Trust Company Americas, and any co-paying agent chosen by
Deutsche Bank Trust Company Americas, and acceptable to the CARAT Owner Trustee.
Deutsche Bank Trust Company Americas shall be permitted to resign as Paying
Agent upon 30 days' written notice to the CARAT Owner Trustee. If Deutsche Bank
Trust Company Americas shall no longer be the Paying Agent, the CARAT Owner
Trustee shall appoint a successor to act as Paying Agent (which shall be a bank
or trust company). The CARAT Owner Trustee shall cause such successor Paying
Agent or any additional Paying Agent appointed by the CARAT Owner Trustee to
execute and deliver to the CARAT Owner Trustee an instrument in which such
successor Paying Agent or additional Paying Agent shall agree with the CARAT
Owner Trustee that as Paying Agent, such successor Paying Agent or additional
Paying Agent shall hold all sums, if any, held by it for payment to the CARAT
2007-SN1 Certificateholders in trust for the benefit of the CARAT 2007-SN1
Certificateholders entitled thereto until such sums shall be paid to such CARAT
2007-SN1 Certificateholders. The Paying Agent shall return all unclaimed funds
to the CARAT Owner Trustee and upon removal of a Paying Agent such Paying Agent
shall also return all funds in its possession to the CARAT Owner Trustee. The
provisions of Sections 6.3, 6.6, 6.7 and 6.9 shall apply to the CARAT Owner
Trustee also in its role as Paying Agent, for so long as the CARAT Owner Trustee
shall act as Paying Agent and, to the extent applicable, to any other paying
agent, certificate registrar or authenticating agent appointed


                                       10



hereunder. Any reference in this Agreement to the Paying Agent shall include any
co-paying agent unless the context requires otherwise.

     Section 3.10 Seller as CARAT 2007-SN1 Certificateholder. The Seller in its
individual or any other capacity may become the owner or pledgee of CARAT
2007-SN1 Certificates and may otherwise deal with the CARAT Owner Trustee or its
Affiliates as if it were not the Seller.

                                   ARTICLE IV
                         ACTIONS BY CARAT OWNER TRUSTEE

     Section 4.1 Prior Notice to CARAT 2007-SN1 Certificateholders with Respect
to Certain Matters. The CARAT Owner Trustee shall not take action with respect
to the following matters, unless (i) the CARAT Owner Trustee shall have notified
the CARAT 2007-SN1 Certificateholders in writing of the proposed action at least
30 days and not more than 45 days before the taking of such action, and (ii) the
CARAT 2007-SN1 Certificateholders shall not have notified the CARAT Owner
Trustee in writing prior to the 30th day after such notice is given that such
CARAT 2007-SN1 Certificateholders have withheld consent or provided alternative
direction:

          (a) the initiation of any claim or lawsuit by the Trust (other than an
action to collect on a COLT 2007-SN1 Secured Note or an action by the CARAT
Indenture Trustee pursuant to the CARAT Indenture) and the compromise of any
action, claim or lawsuit brought by or against the Trust (other than an action
to collect on a COLT 2007-SN1 Secured Note or an action by the CARAT Indenture
Trustee pursuant to the CARAT Indenture);

          (b) the election by the Trust to file an amendment to the Certificate
of Trust, a conformed copy of which is attached hereto as Exhibit B;

          (c) the amendment of the CARAT Indenture by a supplemental indenture
in circumstances where the consent of any CARAT 2007-SN1 Noteholder is required;

          (d) the amendment of the CARAT Indenture by a supplemental indenture
in circumstances where the consent of any CARAT 2007-SN1 Noteholder is not
required and such amendment materially adversely affects the interests of the
CARAT 2007-SN1 Certificateholders;

          (e) the amendment, change or modification of the Trust Sale and
Administration Agreement, except to cure any ambiguity or to amend or supplement
any provision in a manner that would not materially adversely affect the
interests of the CARAT 2007-SN1 Certificateholders; or

          (f) the appointment pursuant to the CARAT Indenture of a successor
Note Registrar, Paying Agent or CARAT Indenture Trustee or pursuant to this
Agreement of a successor Certificate Registrar, or the consent to the assignment
by the Note Registrar, Paying Agent or CARAT Indenture Trustee or Certificate
Registrar of its obligations under the CARAT Indenture or this Agreement, as
applicable.


                                       11



     Section 4.2 Action by CARAT 2007-SN1 Certificateholders with Respect to
Certain Matters. The CARAT Owner Trustee shall not have the power, except upon
the written direction of the CARAT 2007-SN1 Certificateholders, to remove the
Trust Administrator under the Trust Sale and Administration Agreement pursuant
to Section 7.02 thereof, appoint a successor Trust Administrator under the Trust
Sale and Administration Agreement or except as expressly provided in the CARAT
Basic Documents, sell the COLT 2007-SN1 Secured Notes or any interest therein
after the termination of the CARAT Indenture. The CARAT Owner Trustee shall take
the actions referred to in the preceding sentence only upon written instructions
signed by the CARAT 2007-SN1 Certificateholders.

     Section 4.3 Action by CARAT 2007-SN1 Certificateholders with Respect to
Bankruptcy. Notwithstanding any prior termination of this Agreement, the CARAT
Owner Trustee shall not have the power to commence a voluntary proceeding in
bankruptcy relating to the Trust without the unanimous prior approval of all
CARAT 2007-SN1 Certificateholders (including the Seller) and the delivery to the
CARAT Owner Trustee by each such CARAT 2007-SN1 Certificateholder of a
certificate certifying that such CARAT 2007-SN1 Certificateholder reasonably
believes that the Trust is insolvent; provided, however, that under no
circumstances shall the CARAT Owner Trustee commence or join in commencing any
such proceeding prior to the date that is one year and one day after the
termination of the Trust.

     Section 4.4 Restrictions on CARAT 2007-SN1 Certificateholders' Power. The
CARAT 2007-SN1 Certificateholders shall not direct the CARAT Owner Trustee to
take or refrain from taking any action if such action or inaction would be
contrary to any obligation of the Trust or the CARAT Owner Trustee under this
Agreement, including Section 2.3 of this Agreement, or any of the CARAT Basic
Documents, nor shall the CARAT Owner Trustee be obligated to follow any such
direction, if given. The CARAT 2007-SN1 Certificateholders shall not and shall
not direct the CARAT Owner Trustee to take action that would violate the
provisions of Section 6.1 and, if given, the CARAT Owner Trustee shall not be
obligated to follow any such direction.

     Section 4.5 Majority Control. Except as expressly provided herein, any
action that may be taken or consent that may be given or withheld by the CARAT
2007-SN1 Certificateholders under this Agreement shall be effective if such
action is taken or such consent is given or withheld by the Holders of CARAT
2007-SN1 Certificates evidencing not less than a majority of the Voting
Interests as of the close of the preceding Distribution Date. Except as
expressly provided herein, any written notice, instruction, direction or other
document of the CARAT 2007-SN1 Certificateholders delivered pursuant to this

evidencing not less than a majority of the Voting Interests at the time of the
delivery of such notice.

                                   ARTICLE V
                   APPLICATION OF TRUST FUNDS; CERTAIN DUTIES

     Section 5.1 Establishment of Certificate Distribution Account.

          (a) Except as otherwise provided in Section 5.2, the Trust
Administrator, for the benefit of the CARAT 2007-SN1 Certificateholders, shall
establish and maintain in the name


                                       12



of the Trust an Eligible Deposit Account known as the Capital Auto Receivables
Asset Trust 2007-SN1 Certificate Distribution Account (the "Certificate
Distribution Account"), bearing an additional designation clearly indicating
that the funds deposited therein are held for the benefit of the CARAT 2007-SN1
Certificateholders.

          (b) The Trust shall possess all right, title and interest in and to
all funds on deposit from time to time in the Certificate Distribution Account
and in all proceeds thereof. Except as otherwise provided herein in the CARAT
Indenture, or in the Trust Sale and Administration Agreement, the Certificate
Distribution Account shall be under the sole dominion and control of the CARAT
Owner Trustee for the benefit of the CARAT 2007-SN1 Certificateholders. If, at
any time, the Certificate Distribution Account ceases to be an Eligible Deposit
Account, the CARAT Owner Trustee (or the Trust Administrator on behalf of the
CARAT Owner Trustee, if the Certificate Distribution Account is not then held by
the CARAT Owner Trustee or an Affiliate thereof) shall within 10 Business Days
(or such longer period, not to exceed 30 calendar days, as to which each Rating
Agency may consent) establish a new Certificate Distribution Account as an
Eligible Deposit Account and shall transfer any cash and/or any investments to
such new Certificate Distribution Account.

     Section 5.2 Application of Trust Funds.

          (a) On each Distribution Date, the CARAT Owner Trustee shall
distribute to the CARAT 2007-SN1 Certificateholders, on a pro rata basis,
amounts equal to the amounts deposited in the Certificate Distribution Account
pursuant to Sections 4.05 and 8.01 of the Trust Sale and Administration
Agreement on or prior to such Distribution Date. Notwithstanding the foregoing
or anything else to the contrary in this Agreement or the other CARAT Basic
Documents, if and for so long as CARAT 2007-SN1 Certificates representing in the
aggregate a 100% Voting Interest in the Trust are held by the Seller, (i) no
Certificate Distribution Account shall be required to be established or
maintained and (ii) all distributions and payments on the CARAT 2007-SN1
Certificates (including the final distribution as contemplated by Section
7.1(c)) required hereunder or under the Trust Sale and Administration Agreement
shall be made directly to the Seller by the CARAT Indenture Trustee (whether or
not the Trust Sale and Administration Agreement otherwise contemplates deposit
into the Certificate Distribution Account) and the CARAT Owner Trustee shall
have no duty or liability to see to such distribution.

          (b) On each Distribution Date, the CARAT Owner Trustee shall send to
each CARAT 2007-SN1 Certificateholder the statement provided to the CARAT Owner
Trustee by the Trust Administrator pursuant to Section 4.07(a) of the Trust Sale
and Administration Agreement on such Distribution Date setting forth, among
other things, the amount distributed on the CARAT 2007-SN1 Certificates and the
Administration Fee with respect to such Distribution Date or Monthly Period, as
applicable; provided, however, that no such statement shall be required to be
sent by the CARAT Owner Trustee if and for so long as the Seller is the sole
CARAT 2007-SN1 Certificateholder.

          (c) If any withholding tax is imposed on the Trust's payment (or
allocations of income) to a CARAT 2007-SN1 Certificateholder, such tax shall
reduce the amount otherwise distributable to the CARAT 2007-SN1
Certificateholder in accordance with this Section 5.2;


                                       13



provided, however, that the CARAT Owner Trustee shall not have an obligation to
withhold any such amount if and for so long as the Seller is the sole CARAT
2007-SN1 Certificateholder. The CARAT Owner Trustee is hereby authorized and
directed to retain from amounts otherwise distributable to the CARAT 2007-SN1
Certificateholders sufficient funds for the payment of any tax that is legally
owed by the Trust (but such authorization shall not prevent the CARAT Owner
Trustee from contesting any such tax in appropriate proceedings and withholding
payment of such tax, if permitted by law, pending the outcome of such
proceedings). The amount of any withholding tax imposed with respect to a CARAT
2007-SN1 Certificateholder shall be treated as cash distributed to such CARAT
2007-SN1 Certificateholder at the time it is withheld by the Trust and remitted
to the appropriate taxing authority. If there is a possibility that withholding
tax is payable with respect to a distribution (such as a distribution to a
non-U.S. CARAT 2007-SN1 Certificateholder), the CARAT Owner Trustee may in its
sole discretion withhold such amounts in accordance with this Section 5.2(c). If
a CARAT 2007-SN1 Certificateholder wishes to apply for a refund of any such
withholding tax, the CARAT Owner Trustee shall reasonably cooperate with such
CARAT 2007-SN1 Certificateholder in making such claim so long as such CARAT
2007-SN1 Certificateholder agrees to reimburse the CARAT Owner Trustee for any
out-of-pocket expenses incurred.

          (d) If the CARAT Indenture Trustee holds escheated funds for payment
to the Trust pursuant to Section 3.3(e) of the CARAT Indenture, the CARAT Owner
Trustee shall, upon notice from the CARAT Indenture Trustee that such funds
exist, submit on behalf of the Trust an Issuer Order to the CARAT Indenture
Trustee pursuant to Section 3.3(e) of the CARAT Indenture instructing the CARAT
Indenture Trustee to pay such funds to or at the order of the Seller.

     Section 5.3 Method of Payment. Subject to Section 7.1(c), distributions
required to be made to CARAT 2007-SN1 Certificateholders on any Distribution
Date shall be made to each CARAT 2007-SN1 Certificateholder of record on the
related Record Date (i) by wire transfer, in immediately available funds, to the
account of such Holder at a bank or other entity having appropriate facilities
therefor, if such CARAT 2007-SN1 Certificateholder shall have provided to the
Certificate Registrar appropriate written instructions at least five Business
Days prior to such Record Date or if not, by check mailed to such CARAT 2007-SN1
Certificateholder at the address of such CARAT 2007-SN1 Certificateholder
appearing in the Certificate Register.

     Section 5.4 Accounting and Reports to the CARAT 2007-SN1
Certificateholders, the Internal Revenue Service and Others. The CARAT Owner
Trustee shall maintain (or cause to be maintained) the books of the Trust on a
calendar year basis on the accrual method of accounting, deliver to each CARAT
2007-SN1 Certificateholder, as may be required by the Code and applicable
Treasury Regulations or otherwise, such information as may be required to enable
each CARAT 2007-SN1 Certificateholder to prepare its federal income tax return,
file such tax returns relating to the Trust and make such elections as may from
time to time be required or appropriate under any applicable State or federal
statute or rule or regulation thereunder so as to maintain the Trust's
characterization as an entity described in clause (a) of Section 2.11 for
federal income tax purposes, cause such tax returns to be signed in the manner
required by law and collect or cause to be collected any withholding tax as
described in and in accordance with Section 5.2(c) with respect to income or
distributions to CARAT 2007-SN1 Certificateholders. If the Trust were to become
a partnership in accordance with Section 2.11 or Internal Revenue


                                       14



Service were to contend successfully that the Trust is not a disregarded entity
but is rather a partnership for federal income tax purposes, the Trust shall
allocate items of income, gain, deduction and loss to the partners of the Trust
in accordance with their economic interests in the Trust. With respect to
interest expense of the Trust, the Trust shall allocate to the CARAT 2007-SN1
Certificateholders their share of the entire amount of such interest expense. If
the Trust becomes a partnership, the Seller shall be the tax matters partner and
such partnership shall not make the election described in Section 754 of the
Code.

     Section 5.5 Signature on Returns; Other Tax Matters. The CARAT Owner
Trustee shall sign on behalf of the Trust any and all tax returns of the Trust,
unless applicable law requires a CARAT 2007-SN1 Certificateholder to sign such
documents, in which case such documents shall be signed by the Seller. To the
extent one may be required, the Seller shall be the "tax matters partner" of the
Trust pursuant to the Code.

                                   ARTICLE VI
                             THE CARAT OWNER TRUSTEE

     Section 6.1 Duties of CARAT Owner Trustee.

          (a) The CARAT Owner Trustee undertakes to perform such duties, and
only such duties, as are specifically set forth in this Agreement and the other
CARAT Basic Documents, including the administration of the Trust in the interest
of the CARAT 2007-SN1 Certificateholders, subject to the CARAT Basic Documents
and in accordance with the provisions of this Agreement. No implied covenants or
obligations shall be read into this Agreement.

          (b) Notwithstanding the foregoing, the CARAT Owner Trustee shall be
deemed to have discharged its duties and responsibilities hereunder and under
the CARAT Basic Documents to the extent the Trust Administrator has agreed in
the Trust Sale and Administration Agreement to perform any act or to discharge
any duty of the CARAT Owner Trustee hereunder or under any CARAT Basic Document,
and the CARAT Owner Trustee shall not be liable for the default or failure of
the Trust Administrator to carry out its obligations under the Trust Sale and
Administration Agreement.

          (c) In the absence of bad faith on its part, the CARAT Owner Trustee
may conclusively rely upon certificates or opinions furnished to the CARAT Owner
Trustee and conforming to the requirements of this Agreement in determining the
truth of the statements and the correctness of the opinions contained therein;
provided, however, that the CARAT Owner Trustee shall have examined such
certificates or opinions so as to determine compliance of the same with the
requirements of this Agreement.

          (d) The CARAT Owner Trustee may not be relieved from liability for its
own negligent action, its own negligent failure to act or its own willful
misconduct, except that:

               (i) this Section 6.1(d) shall not limit the effect of Section
6.1(a) or (b);


                                       15



               (ii) the CARAT Owner Trustee shall not be liable for any error of
judgment made in good faith by a Responsible Officer unless it is proved that
the CARAT Owner Trustee was negligent in ascertaining the pertinent facts;

               (iii) the CARAT Owner Trustee shall not be liable with respect to
any action it takes or omits to take in good faith in accordance with a
direction received by it pursuant to Section 4.1, 4.2 or 6.4; and

               (iv) the CARAT Owner Trustee shall not be personally liable for
special, consequential or punitive damages, however styled, including lost
profits.

          (e) Subject to Sections 5.1 and 5.2, monies received by the CARAT
Owner Trustee hereunder need not be segregated in any manner except to the
extent required by law or the Trust Sale and Administration Agreement and may be
deposited under such general conditions as may be prescribed by law, and the
CARAT Owner Trustee shall not be liable for any interest thereon.

          (f) The CARAT Owner Trustee shall not take any action that (i) is
inconsistent with the purposes of the Trust set forth in Section 2.3 or (ii)
would, to the actual knowledge of a Responsible Officer of the CARAT Owner
Trustee, result in the Trust's becoming taxable as a corporation for federal
income tax purposes. The CARAT 2007-SN1 Certificateholders shall not direct the
CARAT Owner Trustee to take action that would violate the provisions of this
Section 6.1.

     Section 6.2 Rights of CARAT Owner Trustee. The CARAT Owner Trustee is
authorized and directed to execute and deliver the CARAT Basic Documents and
each certificate or other document attached as an exhibit to or contemplated by
the CARAT Basic Documents to which the Trust is to be a party, in such form as
the Seller shall approve as evidenced conclusively by the CARAT Owner Trustee's
execution thereof. In addition to the foregoing, the CARAT Owner Trustee is
authorized, but shall not be obligated, to take all actions required of the
Trust pursuant to the CARAT Basic Documents. The CARAT Owner Trustee is further
authorized from time to time to take such action as the Trust Administrator
recommends and directs in writing with respect to the CARAT Basic Documents.

     Section 6.3 Acceptance of Trusts and Duties. Except as otherwise provided
in this Article VI, in accepting the trusts hereby created, Deutsche Bank Trust
Company Delaware acts solely as CARAT Owner Trustee hereunder and not in its
individual capacity and all Persons having any claim against the CARAT Owner
Trustee by reason of the transactions contemplated by this Agreement or any
other CARAT Basic Document shall look only to the CARAT Owner Trust Estate for
payment or satisfaction thereof. The CARAT Owner Trustee accepts the trusts
hereby created and agrees to perform its duties hereunder with respect to such
trusts but only upon the terms of this Agreement. The CARAT Owner Trustee also
agrees to disburse all monies actually received by it constituting part of the
CARAT Owner Trust Estate upon the terms of the CARAT Basic Documents. The CARAT
Owner Trustee shall not be liable or accountable hereunder or under any CARAT
Basic Document under any circumstances, except for its own negligent action, its
own negligent failure to act or its own willful misconduct or in the case of the
inaccuracy of any representation or warranty contained in Section 6.6 and


                                       16



expressly made by the CARAT Owner Trustee. In particular, but not by way of
limitation (and subject to the exceptions set forth in the preceding sentence):

          (a) the CARAT Owner Trustee shall at no time have any responsibility
or liability for, or with respect to, the legality, validity and enforceability
of any COLT 2007-SN1 Secured Note, or the perfection and priority of any
security interest created by any COLT 2007-SN1 Secured Note in any Series
2007-SN1 Lease Asset or the maintenance of any such perfection and priority, or
for, or with respect to, the sufficiency of the CARAT Owner Trust Estate or its
ability to generate the payments to be distributed to CARAT 2007-SN1
Certificateholders under this Agreement or to CARAT 2007-SN1 Noteholders under
the CARAT Indenture, including, without limitation: the existence, condition and
ownership of any Series 2007-SN1 Lease Asset securing a COLT 2007-SN1 Secured
Note; the existence and enforceability of any insurance thereon; the existence
and contents of any COLT 2007-SN1 Secured Note on any computer or other record
thereof; the validity of the assignment of any COLT 2007-SN1 Secured Note to the
Trust or of any intervening assignment; the completeness of any COLT 2007-SN1
Secured Note; the performance or enforcement of any COLT 2007-SN1 Secured Note;
the compliance by the Seller or the Trust Administrator with any warranty or
representation made under any CARAT Basic Document or in any related document or
the accuracy of any such warranty or representation or any action of the Trustee
or the Trust Administrator or any sub-administrator taken in the name of the
CARAT Owner Trustee;

          (b) the CARAT Owner Trustee shall not be liable with respect to any
action taken or omitted to be taken by it in accordance with the instructions of
the Trust Administrator or any CARAT 2007-SN1 Certificateholder;

          (c) no provision of this Agreement or any other CARAT Basic Document
shall require the CARAT Owner Trustee to expend or risk funds or otherwise incur
any financial liability in the performance of any of its rights or powers
hereunder or under any other CARAT Basic Document, if the CARAT Owner Trustee
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured or
provided to it;

          (d) under no circumstances shall the CARAT Owner Trustee be liable for
indebtedness evidenced by or arising under any of the CARAT Basic Documents,
including the principal of and interest on the CARAT 2007-SN1 Notes;

          (e) the CARAT Owner Trustee shall not be responsible for or in respect
of and makes no representation as to the validity or sufficiency of any
provision of this Agreement other than as explicitly set forth herein or for the
due execution hereof by the Seller or for the form, character, genuineness,
sufficiency, value or validity of any of the CARAT Owner Trust Estate or for, or
in respect of, the validity or sufficiency of the CARAT Basic Documents, the
CARAT 2007-SN1 Notes, the CARAT 2007-SN1 Certificates (other than the
certificate of authentication on the CARAT 2007-SN1 Certificates) or of any COLT
2007-SN1 Secured Notes or any related documents, and the CARAT Owner Trustee
shall in no event assume or incur any liability, duty or obligation to any CARAT
2007-SN1 Noteholder or to any CARAT 2007-SN1 Certificateholder, other than as
expressly provided for herein and in the other CARAT Basic Documents;


                                       17



          (f) the CARAT Owner Trustee shall not be liable for the default or
misconduct of the CARAT Indenture Trustee, the Seller or the Trust Administrator
under any of the CARAT Basic Documents or otherwise and the CARAT Owner Trustee
shall have no obligation or liability to perform the obligations of the Trust
under this Agreement or the other CARAT Basic Documents that are required to be
performed by the CARAT Indenture Trustee under the CARAT Indenture or the Trust
Administrator under the Pooling and Administration Agreement or the Trust Sale
and Administration Agreement; and

          (g) the CARAT Owner Trustee shall be under no obligation to exercise
any of the rights or powers vested in it by this Agreement, or to institute,
conduct or defend any litigation under this Agreement or otherwise or in
relation to this Agreement or any other CARAT Basic Document, at the request,
order or direction of any of the CARAT 2007-SN1 Certificateholders, unless such
CARAT 2007-SN1 Certificateholders have offered to the CARAT Owner Trustee
security or indemnity satisfactory to it against the costs, expenses and
liabilities that may be incurred by the CARAT Owner Trustee therein or thereby;
the right of the CARAT Owner Trustee to perform any discretionary act enumerated
in this Agreement or in any other CARAT Basic Document shall not be construed as
a duty, and the CARAT Owner Trustee shall not be answerable for other than its
negligence or willful misconduct in the performance of any such act.

          (h) notwithstanding anything to the contrary contained herein or in
any other CARAT Basic Document, the CARAT Owner Trustee shall not be required to
execute, deliver or certify on behalf of the Trust or any other Person any
filings, certificates, affidavits or other instruments required under the
Sarbanes-Oxley Act of 2002; notwithstanding any Person's right to instruct the
CARAT Owner Trustee, neither the CARAT Owner Trustee nor any agent, employee,
director or officer of the CARAT Owner Trustee shall have any obligation to
execute any certificates or other documents required pursuant to the
Sarbanes-Oxley Act of 2002 or the rules and regulations promulgated pursuant
thereto, and the refusal to comply with any such instructions shall not
constitute a default or breach under any CARAT Basic Document; if the CARAT
Owner Trustee, on behalf of the Trust, does not execute, deliver or certify any
filings, certificates, affidavits or other instruments required under the
Sarbanes-Oxley Act of 2002, an Officer of the Trust Administrator shall, on
behalf of the Trust, execute, deliver or make such certification.

     Section 6.4 Action Upon Instruction by CARAT 2007-SN1 Certificateholders.

          (a) Subject to Section 4.4, the CARAT 2007-SN1 Certificateholders may
by written instruction direct the CARAT Owner Trustee in the management of the
Trust. Such direction may be exercised at any time by written instruction of the
CARAT 2007-SN1 Certificateholders pursuant to Section 4.5.

          (b) Notwithstanding the foregoing, the CARAT Owner Trustee shall not
be required to take any action hereunder or under any other CARAT Basic Document
if the CARAT Owner Trustee shall have reasonably determined, or shall have been
advised by counsel, that such action is likely to result in liability on the
part of the CARAT Owner Trustee or is contrary to the terms hereof or of any
other CARAT Basic Document or is otherwise contrary to law.


                                       18



          (c) Whenever the CARAT Owner Trustee is unable to decide between
alternative courses of action permitted or required by the terms of this
Agreement or any other CARAT Basic Document, or is unsure as to the application,
intent, interpretation or meaning of any provision of this Agreement or any
other CARAT Basic Document, the CARAT Owner Trustee shall promptly give notice
(in such form as shall be appropriate under the circumstances) to the CARAT
2007-SN1 Certificateholders requesting instruction as to the course of action to
be adopted, and, to the extent the CARAT Owner Trustee acts in good faith in
accordance with any such instruction received, the CARAT Owner Trustee shall not
be liable on account of such action to any Person. If the CARAT Owner Trustee
shall not have received appropriate instructions within ten days of such notice
(or within such shorter period of time as reasonably may be specified in such
notice or may be necessary under the circumstances) it may, but shall be under
no duty to, take or refrain from taking such action which is consistent, in its
view, with this Agreement or any other CARAT Basic Document, and as it shall
deem to be in the best interests of the CARAT 2007-SN1 Certificateholders, and
the CARAT Owner Trustee shall have no liability to any Person for any such
action or inaction.

     Section 6.5 Furnishing of Documents. The CARAT Owner Trustee shall furnish
to the CARAT 2007-SN1 Certificateholders, promptly upon receipt of a written
request therefor, duplicates or copies of all reports, notices, requests,
demands, certificates, financial statements and any other instruments furnished
to the CARAT Owner Trustee under the CARAT Basic Documents.

     Section 6.6 Representations and Warranties of CARAT Owner Trustee. The
CARAT Owner Trustee hereby represents and warrants to the Seller, for the
benefit of the CARAT 2007-SN1 Certificateholders, that:

          (a) It is a banking corporation duly organized, validly existing and
in good standing under the laws of the State of its incorporation. It has
satisfied the eligibility requirements set forth in Section 6.13.

          (b) It has full power, authority and legal right to execute, deliver
and perform this Agreement, and has taken all necessary action to authorize the
execution, delivery and performance by it of this Agreement.

          (c) The execution, delivery and performance by it of this Agreement
(i) shall not violate any provision of any law or regulation governing the
banking and trust powers of the CARAT Owner Trustee or any order, writ, judgment
or decree of any court, arbitrator or governmental authority applicable to the
CARAT Owner Trustee or any of its assets, (ii) shall not violate any provision
of the corporate charter or by-laws of the CARAT Owner Trustee or (iii) shall
not violate any provision of, or constitute, with or without notice or lapse of
time, a default under, or result in the creation or imposition of any Lien
(other than tax liens and any other Liens that attach by operation of law) on
any properties included in the Trust pursuant to the provisions of any mortgage,
indenture, contract, agreement or other undertaking to which it is a party,
which violation, default or Lien (other than tax liens and any other Liens that
attach by operation of law) could reasonably be expected to have a materially
adverse effect on the CARAT Owner Trustee's performance or ability to perform
its duties as CARAT Owner Trustee under this Agreement or on the transactions
contemplated in this Agreement.


                                       19



          (d) This Agreement has been duly executed and delivered by the CARAT
Owner Trustee and constitutes the legal, valid and binding agreement of the
CARAT Owner Trustee, 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.

     Section 6.7 Reliance; Advice of Counsel.

          (a) The CARAT Owner Trustee shall incur no liability to anyone in
acting upon any signature, instrument, notice, resolution, request, consent,
order, certificate, report, opinion, bond or other document or paper believed by
it to be genuine and believed by it to be signed by the proper party or parties
and need not investigate any fact or matter in any such document. The CARAT
Owner Trustee may accept a certified copy of a resolution of the board of
directors or other governing body of any corporate party as conclusive evidence
that such resolution has been duly adopted by such body and that the same is in
full force and effect. As to any fact or matter the method of the determination
of which is not specifically prescribed herein, the CARAT Owner Trustee may for
all purposes hereof rely on a certificate, signed by the president or any vice
president or by the treasurer or other authorized officers of the relevant
party, as to such fact or matter, and such certificate shall constitute full
protection to the CARAT Owner Trustee for any action taken or omitted to be
taken by it in good faith in reliance thereon.

          (b) In the exercise or administration of the trusts hereunder and in
the performance of its duties and obligations under this Agreement or the CARAT
Basic Documents, the CARAT Owner Trustee may act directly or through its agents,
attorneys, custodians or nominees (including the granting of a power of attorney
to officers of Deutsche Bank Trust Company Americas to execute and deliver any
CARAT Basic Documents, CARAT 2007-SN1 Certificate, CARAT 2007-SN1 Note or other
documents related thereto on behalf of the CARAT Owner Trustee) pursuant to
agreements entered into with any of them, and the CARAT Owner Trustee shall not
be liable for the conduct or misconduct of such agents, attorneys, custodians or
nominees if such agents, attorneys, custodians or nominees shall have been
selected by the CARAT Owner Trustee with reasonable care; and may consult with
counsel, accountants and other skilled professionals to be selected with
reasonable care and employed by it. The CARAT Owner Trustee shall not be liable
for anything done, suffered or omitted in good faith by it in accordance with
the opinion or advice of any such counsel, accountants or other such Persons and
not contrary to this Agreement or any CARAT Basic Document.

     Section 6.8 CARAT Owner Trustee May Own CARAT 2007-SN1 Certificates and
CARAT 2007-SN1 Notes. Deutsche Bank Trust Company Delaware or any successor
CARAT Owner Trustee in its individual or any other capacity may become the owner
or pledgee of CARAT 2007-SN1 Certificates or CARAT 2007-SN1 Notes and may deal
with the Seller, the CARAT Indenture Trustee and the Trust Administrator in
transactions in the same manner as it would have if it were not the CARAT Owner
Trustee.

     Section 6.9 Compensation and Indemnity. The CARAT Owner Trustee shall
receive as compensation for its services hereunder such fees as have been
separately agreed upon before the date hereof between the Trust Administrator
and the CARAT Owner Trustee, and the


                                       20



CARAT Owner Trustee, any Paying Agent, registrar, authenticating agent or
co-trustee shall be entitled to be reimbursed by the Trust Administrator for its
other reasonable expenses hereunder, including the reasonable compensation,
expenses and disbursements of such agents, custodians, nominees,
representatives, experts and external counsel as the CARAT Owner Trustee may
employ in connection with the exercise and performance of its rights and its
duties hereunder. The Trust Administrator shall indemnify the CARAT Owner
Trustee, any Paying Agent, registrar, authenticating agent or co-trustee and its
successors, assigns, agents and servants in accordance with the provisions of
Section 6.01 of the Trust Sale and Administration Agreement. The indemnities
contained in this Section 6.9 shall survive the resignation or removal of the
CARAT Owner Trustee or the termination of this Agreement. Any amounts paid to
the CARAT Owner Trustee pursuant to this Article VI shall be deemed not to be a
part of the CARAT Owner Trust Estate immediately after such payment.

     Section 6.10 Replacement of CARAT Owner Trustee.

          (a) The CARAT Owner Trustee may give notice of its intent to resign
and be discharged from the trusts hereby created by giving notice thereof to the
Trust Administrator provided, however, that no such resignation shall become
effective, and the CARAT Owner Trustee shall not resign, prior to the time set
forth in Section 6.10(c). If no successor CARAT Owner Trustee shall have been
appointed pursuant to Section 6.10(b) and have accepted such appointment within
30 days after the giving of such notice, the CARAT Owner Trustee giving such
notice may petition any court of competent jurisdiction for the appointment of a
successor CARAT Owner Trustee. The Trust Administrator shall remove the CARAT
Owner Trustee if:

               (i) the CARAT Owner Trustee shall cease to be eligible in
accordance with the provisions of Section 6.13 and shall fail to resign after
written request therefor by the Trust Administrator;

               (ii) the CARAT Owner Trustee shall be adjudged bankrupt or
insolvent;

               (iii) a receiver or other public officer shall be appointed or
take charge or control of the CARAT Owner Trustee or of its property or affairs
for the purpose of rehabilitation, conservation or liquidation; or

               (iv) the CARAT Owner Trustee shall otherwise be incapable of
acting.

          (b) If the CARAT Owner Trustee gives notice of its intent to resign or
is removed or if a vacancy exists in the office of CARAT Owner Trustee for any
reason the Trust Administrator shall promptly appoint a successor CARAT Owner
Trustee by written instrument, in duplicate (one copy of which instrument shall
be delivered to the outgoing CARAT Owner Trustee so removed and one copy to the
successor CARAT Owner Trustee) and shall pay all fees owed to the outgoing CARAT
Owner Trustee.

          (c) Any resignation or removal of the CARAT Owner Trustee and
appointment of a successor CARAT Owner Trustee pursuant to any of the provisions
of this Section 6.10 shall not become effective and no such resignation shall be
deemed to have occurred until a written acceptance of appointment is delivered
by the successor CARAT Owner


                                       21



Trustee to the outgoing CARAT Owner Trustee and the Trust Administrator and all
fees and expenses due to the outgoing CARAT Owner Trustee are paid. Any
successor CARAT Owner Trustee appointed pursuant to this Section 6.10 shall be
eligible to act in such capacity in accordance with Section 6.13 and, following
compliance with the preceding sentence, shall become fully vested with all the
rights, powers, duties and obligations of its predecessor under this Agreement,
with like effect as if originally named as CARAT Owner Trustee. The Trust
Administrator shall provide notice of such resignation or removal of the CARAT
Owner Trustee to the Rating Agencies.

          (d) The predecessor CARAT Owner Trustee shall upon payment of its fees
and expenses deliver to the successor CARAT Owner Trustee all documents and
statements and monies held by it under this Agreement. The Trust Administrator
and the predecessor CARAT Owner Trustee shall execute and deliver such
instruments and do such other things as may reasonably be required for fully and
certainly vesting and confirming in the successor CARAT Owner Trustee all such
rights, powers, duties and obligations.

          (e) Upon acceptance of appointment by a successor CARAT Owner Trustee
pursuant to this Section 6.10, the Trust Administrator shall mail notice of the
successor of such CARAT Owner Trustee to all CARAT 2007-SN1 Certificateholders,
the CARAT Indenture Trustee, the CARAT 2007-SN1 Noteholders and the Rating
Agencies.

     Section 6.11 Merger or Consolidation of CARAT Owner Trustee. Any Person
into which the CARAT Owner Trustee may be merged or converted or with which it
may be consolidated, or any Person resulting from any merger, conversion or
consolidation to which the CARAT Owner Trustee shall be a party, or any Person
succeeding to all or substantially all of the corporate trust business of the
CARAT Owner Trustee, shall be the successor of the CARAT Owner Trustee
hereunder, provided such Person shall be eligible pursuant to Section 6.13, and
without the execution or filing of any instrument or any further act on the part
of any of the parties hereto; provided, however, that the CARAT Owner Trustee
shall mail notice of such merger or consolidation to the Rating Agencies.

     Section 6.12 Appointment of Co-Trustee or Separate Trustee.

          (a) Notwithstanding any other provisions of this Agreement, at any
time, for the purpose of meeting any legal requirement of any jurisdiction in
which any part of the CARAT Owner Trust Estate or any COLT 2007-SN1 Secured Note
may at the time be located, the Trust Administrator and the CARAT Owner Trustee
acting jointly shall have the power and shall, at the expense of the Trust
Administrator, execute and deliver all instruments to appoint one or more
Persons approved by the CARAT Owner Trustee to act as co-trustee, jointly with
the CARAT Owner Trustee, or as separate trustee or trustees, of all or any part
of the CARAT Owner Trust Estate, and to vest in such Person (in the name of the
Trust and not in such Person's name for the Trust, except to the extent
otherwise required by, and in accordance with, Section 2.8), in such capacity,
such title to the Trust, or any part thereof, and, subject to the other
provisions of this Section 6.12, such powers, duties, obligations, rights and
trusts as the Trust Administrator and the CARAT Owner Trustee may consider
necessary or desirable. If the Trust Administrator shall not have joined in such
appointment within 15 days after the receipt by it of a request so to do, the
CARAT Owner Trustee alone shall have the power to make such


                                       22



appointment. No co-trustee or separate trustee under this Agreement shall be
required to meet the terms of eligibility as a successor trustee pursuant to
Section 6.13 and no notice of the appointment of any co-trustee or separate
trustee shall be required pursuant to Section 6.10.

          (b) Each separate trustee and co-trustee shall, to the extent
permitted by law, be appointed and act subject to the following provisions and
conditions:

               (i) all rights, powers, duties and obligations conferred or
imposed upon the CARAT Owner Trustee shall be conferred upon and exercised or
performed by the CARAT Owner Trustee and such separate trustee or co-trustee
jointly (it being understood that such separate trustee or co-trustee is not
authorized to act separately without the CARAT Owner Trustee joining in such
act), except to the extent that under any law of any jurisdiction in which any
particular act or acts are to be performed, the CARAT Owner Trustee shall be
incompetent or unqualified to perform such act or acts, in which event such
rights, powers, duties and obligations (including the holding of title to the
Trust or any portion thereof in any such jurisdiction) shall be exercised and
performed singly by such separate trustee or co-trustee, but solely at the
direction of the CARAT Owner Trustee;

The bankruptcy, liquidation, dissolution, death or incapacity of any CARAT

the Trust, (y) entitle such CARAT 2007-SN1 Certificateholder's legal

Agent therein specified. The


                                       24



CARAT Owner Trustee shall give such notice to the Certificate Registrar (if
other than the CARAT Owner Trustee) and the Paying Agent at the time such notice
is given to CARAT 2007-SN1 Certificateholders. Upon presentation and surrender
of the CARAT 2007-SN1 Certificates, the Paying Agent shall cause to be
distributed to CARAT 2007-SN1 Certificateholders amounts distributable on such
Distribution Date pursuant to Section 5.2.

          (d) If all of the CARAT 2007-SN1 Certificateholders shall not
surrender their CARAT 2007-SN1 Certificates for cancellation within six months

the CARAT Owner Trustee shall give a second written notice to the remaining
CARAT 2007-SN1 Certificateholders to surrender their CARAT 2007-SN1 Certificates
for cancellation and receive the final distribution with respect thereto. If
within one year after the second notice all the CARAT 2007-SN1 Certificates
shall not have been surrendered for cancellation, the CARAT Owner Trustee may
take appropriate steps, or may appoint an agent to take appropriate steps, to
contact the remaining CARAT 2007-SN1 Certificateholders concerning surrender of
their CARAT 2007-SN1 Certificates, and the cost thereof shall be paid out of the
funds and other assets that shall remain subject to this Agreement. Subject to
applicable laws with respect to escheat of funds, any funds remaining in the
Trust after exhaustion of such remedies in the preceding sentence shall be
deemed property of the Seller and distributed by the CARAT Owner Trustee to the
Seller, and the CARAT Owner Trustee shall have no further liability to the CARAT
2007-SN1 Certificateholders with respect thereto.

          (e) Upon the winding up and termination of the Trust in accordance
with Section 3808 of the Statutory Trust Act and this Section, the CARAT Owner
Trustee shall cause the Certificate of Trust to be canceled by filing a
certificate of cancellation with the Secretary of State in accordance with the
provisions of Section 3810 of the Statutory Trust Act.

     evidencing a fractional undivided interest in the Trust, as defined below,
     the property of which includes the COLT 2007-SN1 Secured Notes sold to the
     Trust by Capital Auto Receivables LLC

     (This CARAT 2007-SN1 Certificate does not represent an interest in or
     obligation of Capital Auto Receivables LLC, GMAC LLC or General Motors
     Corporation or any of their respective affiliates, except to the extent
     described in the CARAT Basic Documents.)

          THIS CERTIFIES THAT Capital Auto Receivables LLC is the registered
owner of a nonassessable, fully-paid, fractional undivided interest in Capital
Auto Receivables Asset Trust 2007-SN1 (the "Trust") formed by Capital Auto
Receivables LLC, a Delaware limited liability company.

          The Trust was created pursuant to a trust agreement, dated as of May
10, 2007 (as amended and restated as of June 7, 2007 and as it may be amended
from time to time, the "Trust Agreement"), between the Seller and Deutsche Bank
Trust Company Delaware, as owner trustee (the "CARAT Owner Trustee"), a summary
of certain of the pertinent provisions of which is set forth below. To the
extent not otherwise defined herein, the capitalized terms used herein have the
meanings assigned to them in the Trust Agreement.

          This CARAT 2007-SN1 Certificate is one of the duly authorized CARAT
2007-SN1 Certificates designated as Asset Backed Certificates (the "CARAT
2007-SN1 Certificates"). This CARAT 2007-SN1 Certificate is issued under and is
subject to the terms, provisions and conditions of the Trust Agreement, the
terms of which are incorporated herein by reference and made a part hereof, to
which Trust Agreement the holder of this CARAT 2007-SN1 Certificate by virtue of
the acceptance hereof assents and by which such holder is bound.

          Under the Trust Agreement, there shall be distributed on the 15th day
of each month or, if such 15th day is not a Business Day, the next Business Day,
commencing on June 15, 2007 (each, a "Distribution Date"), to the Person in
whose name this CARAT 2007-SN1 Certificate is registered on the related Record
Date (as defined below), such amount as is provided in the CARAT Basic
Documents. The "Record Date," with respect to any Distribution Date, means the
last day of the preceding Monthly Period.

          The distributions in respect of this CARAT 2007-SN1 Certificate are
payable in such coin or currency of the United States of America as at the time
of payment is legal tender for payment of public and private debts. All payments
made by the Trust with respect to this CARAT 2007-SN1 Certificate shall be
applied in respect of this CARAT 2007-SN1 Certificate.

          This CARAT 2007-SN1 Certificate (or interest therein) may not be
acquired by or for the account of a Benefit Plan. By accepting and holding this
CARAT 2007-SN1 Certificate (or interest therein), the Holder hereof shall be
deemed to have represented and warranted that it is not a Benefit Plan and is
not purchasing on behalf of a Benefit Plan and, if requested to do so


                                      A-3



by the Seller pursuant to Section 3.4(f) of the Trust Agreement, the CARAT
2007-SN1 Certificateholder shall execute and deliver to the CARAT Owner Trustee
an undertaking letter in form and substance satisfactory to the CARAT Indenture
Trustee and the Seller.

          The holder of this CARAT 2007-SN1 Certificate acknowledges and agrees
that its rights to receive distributions in respect of this CARAT 2007-SN1
Certificate are subordinated to the rights of the CARAT 2007-SN1 Noteholders as
and to the extent described in the Trust Sale and Administration Agreement until
the CARAT 2007-SN1 Notes are paid in full, such CARAT 2007-SN1 Notes are retired
or cancelled and all amounts owing to the Swap Counterparty have been paid.

          It is the intent of the Seller, the CARAT Owner Trustee and the CARAT
2007-SN1 Certificateholders that, for purposes of federal income, 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 as either (A) a division of the Seller, or any other single
Person, and disregarded as a separate entity, if all CARAT 2007-SN1 Certificates
are owned solely by the Seller or by such single Person, or (B) a partnership if
the CARAT 2007-SN1 Certificates are owned by more than one Person. Except as
otherwise required by appropriate taxing authorities, the Seller and the other
CARAT 2007-SN1 Certificateholders by acceptance of a CARAT 2007-SN1 Certificate
agree to treat, and to take no action inconsistent with the treatment of, the
CARAT 2007-SN1 Certificates for such tax purposes as interests in such a
disregarded entity or partnership as described in the previous sentence.

          Each CARAT 2007-SN1 Certificateholder or CARAT 2007-SN1 Certificate
Owner by its acceptance of a CARAT 2007-SN1 Certificate (or an interest therein)
covenants and agrees that such CARAT 2007-SN1 Certificateholder or CARAT
2007-SN1 Certificate Owner shall not, prior to the date which is one year and
one day after the termination of the Trust, acquiesce, petition or otherwise
invoke or cause the Seller or the CARAT Owner Trustee to invoke the process of
any court or governmental authority for the purpose of commencing or sustaining
a case against the Seller or the CARAT Owner Trustee under any federal or State
bankruptcy, insolvency, reorganization or similar law or appointing a receiver,
liquidator, assignee, trustee, custodian, sequestrator or other similar official
of the Seller or the CARAT Owner Trustee or any substantial part of its
property, or ordering the winding up or liquidation of the affairs of the Seller
or the CARAT Owner Trustee.

          Except as otherwise provided in the Trust Agreement, distributions on
this CARAT 2007-SN1 Certificate shall be made as provided in the Trust Agreement
by the CARAT Owner Trustee by wire transfer or check mailed to the CARAT
2007-SN1 Certificateholder of record in the CARAT 2007-SN1 Certificate Register
without the presentation or surrender of this CARAT 2007-SN1 Certificate or the
making of any notation hereon. Except as otherwise provided in the Trust
Agreement and notwithstanding the above, the final distribution on this CARAT
2007-SN1 Certificate shall be made after due notice by the CARAT Owner Trustee
of the pendency of such distribution and only upon presentation and surrender of
this CARAT 2007-SN1 Certificate at the office maintained for such purpose by the
CARAT Owner Trustee in the Borough of Manhattan, The City of New York.


                                      A-4



          Reference is hereby made to the further provisions of this CARAT
2007-SN1 Certificate set forth on the reverse hereof, which further provisions
shall for all purposes have the same effect as if set forth at this place.

          Unless the certificate of authentication hereon shall have been
executed by an authorized officer of the CARAT Owner Trustee by manual
signature, this CARAT 2007-SN1 Certificate shall not entitle the holder hereof
to any benefit under the Trust Agreement or the Trust Sale and Administration
Agreement or be valid for any purpose.

and not in its individual capacity, has caused this CARAT 2007-SN1 Certificate
to be duly executed.

                             REVERSE OF CERTIFICATE

          The CARAT 2007-SN1 Certificates do not represent an obligation of, or
an interest in, the Seller, the Trust Administrator, General Motors Corporation,
the CARAT Indenture Trustee, the CARAT Owner Trustee or any Affiliates of any of
them and no recourse may be had against such parties or their assets, except as
may be expressly set forth or contemplated herein or in the Trust Agreement or
the other CARAT Basic Documents. In addition, this CARAT 2007-SN1 Certificate is
not guaranteed by any governmental agency or instrumentality and is limited in
right of payment to certain collections and recoveries with respect to the CARAT
2007-SN1 Secured Notes (and certain other amounts), all as more specifically set
forth herein and in the Basic Documents. A copy of each of the CARAT Basic
Documents may be examined during normal business hours at the principal office
of the Seller, and at such other places, if any, designated by the Seller, by
any CARAT 2007-SN1 Certificateholder upon written request. In the event of any
conflict between the terms of this CARAT 2007-SN1 Certificate and the terms of
the CARAT Basic Documents, the terms of the CARAT Basic Documents shall govern.

          The Trust Agreement permits, with certain exceptions provided therein,
the amendment thereof and the modification of the rights and obligations of the

Agreement at any time by the Seller and the CARAT Owner Trustee with the consent
of the Holders of the CARAT 2007-SN1 Notes evidencing not less than a majority
of the Outstanding Amount of the Controlling Class as of the close of the

Affiliate of the Seller holds any CARAT 2007-SN1 Certificates, the consent of
CARAT 2007-SN1 Certificateholders whose CARAT 2007-SN1 Certificates evidence not
less than a majority of the Voting Interests as of the close of the preceding
Distribution Date. Any such consent by the Holder of this CARAT 2007-SN1
Certificate shall be conclusive and binding on such Holder and on all future
Holders of this CARAT 2007-SN1 Certificate and of any CARAT 2007-SN1 Certificate
issued upon the transfer hereof or in exchange herefor or in lieu hereof whether
or not notation of such consent is made upon this CARAT 2007-SN1 Certificate.
The Trust Agreement also permits the amendment thereof, in certain
circumstances, without the consent of the Holders of any of the CARAT 2007-SN1
Certificates or the CARAT 2007-SN1 Notes.

          As provided in the Trust Agreement and subject to certain limitations
therein set forth, the transfer of this CARAT 2007-SN1 Certificate is

Certificate Registrar maintained by the CARAT Owner Trustee in the City of New
York, accompanied by a written instrument of transfer in form satisfactory to
the CARAT Owner Trustee and the Certificate Registrar duly executed by the

percentage interest in the Trust will be issued to the designated transferee.

                                      A-7



Certificates of authorized denominations evidencing the same aggregate
denomination, as requested by the Holder surrendering the same. No service
charge shall be made for any such registration of transfer or exchange, but the
CARAT Owner Trustee or the CARAT 2007-SN1 Certificate Registrar may require
payment of a sum sufficient to cover any tax or governmental charge payable in
connection therewith.

          The CARAT Owner Trustee, the CARAT 2007-SN1 Certificate Registrar and
any agent of the CARAT Owner Trustee or the CARAT 2007-SN1 Certificate Registrar
may treat the Person in whose name this CARAT 2007-SN1 Certificate is registered
as the owner hereof for all purposes, and none of the CARAT Owner Trustee, the

notice to the contrary.

          The obligations and responsibilities created by the Trust Agreement
and the Trust created thereby shall terminate in accordance with Article VII of
the Trust Agreement.
