     It is the intention of the Seller and the Issuer that the transfer and
assignment contemplated by this Agreement and the related Second Step Secured

Dealers, insurers or any other Person in connection with the COLT 2007-SN1
Secured Notes, Series 2007-SN1 Lease Assets, any Dealer Agreements, any
insurance policies or any agreement or instrument relating to any of them.

     Section 2.02 Acceptance by Issuer. The Issuer does hereby accept all
consideration conveyed by the Seller pursuant to Section 2.01, and declares that
the Issuer shall hold such consideration upon the trusts set forth in the Trust
Agreement for the benefit of the CARAT 2007-SN1 Certificateholders, subject to
the terms and conditions of the CARAT Indenture and this Agreement and the
related Second Step Secured Notes Assignment and the rights of the CARAT
2007-SN1 Noteholders with respect thereto. The Issuer hereby agrees to and
accepts the appointment and authorization of GMAC as Trust Administrator under
Section 3.01 of the Pooling and Administration Agreement. The parties agree that
this Agreement, the Second Step Secured Notes Assignment, the CARAT Indenture,
the Trust Agreement, the CARAT 2007-SN1 Notes and the CARAT 2007-SN1 Certificate
constitute the Further Transfer and Administration Agreements for purposes of
the Pooling and Administration Agreement and that the rights, duties


and obligations of GMAC as Trust Administrator under the Pooling and
Administration Agreement are subject to the provisions of Sections 6.02, 6.04,
6.05, 9.01 and Article VII.

     Section 2.03 Representations and Warranties as to the COLT 2007-SN1 Secured
Notes. Pursuant to Section 2.01(d), the Seller assigns to the Issuer all of its
right, title and interest in, to and under the Pooling and Administration
Agreement. Such assigned right, title and interest includes the benefit of the
representations and warranties of GMAC made to the Seller pursuant to Section
4.01 of the Pooling and Administration Agreement. The Seller hereby represents
and warrants to the Issuer that the Seller has taken no action which would cause
such representations and warranties of GMAC to be false in any material respect
as of the Series 2007-SN1 Closing Date. The Seller further acknowledges that the
Issuer and its permitted assigns rely on the representations and warranties of
the Seller under this Agreement and of GMAC under the Pooling and Administration
Agreement in accepting the COLT 2007-SN1 Secured Notes and the other Second Step
Purchased Property in trust and executing and delivering the CARAT 2007-SN1
Notes and the CARAT 2007-SN1 Certificates. The foregoing representation and
warranty speaks as of the Series 2007-SN1 Closing Date, but shall survive the
sale, transfer and assignment of the COLT 2007-SN1 Secured Notes and the other
Second Step Purchased Property to the Issuer and the pledge thereof to the CARAT
Indenture Trustee pursuant to the CARAT Indenture.

     Section 2.04 Repurchase of COLT 2007-SN1 Secured Notes Upon Breach of
Warranty. Upon discovery by the Seller, the Trust Administrator, the CARAT Owner
Trustee or the CARAT Indenture Trustee of a breach of any of the representations
and warranties in Section 4.01 of the Pooling and Administration Agreement or in
Section 2.03 or Section 3.01 of this Agreement that materially and adversely
affects the interests of the CARAT 2007-SN1 Noteholders or the CARAT 2007-SN1
Certificateholders in any COLT 2007-SN1 Secured Note, the party discovering such
breach shall give prompt written notice thereof to the others. As of the last
day of the second Monthly Period following its discovery or its receipt of
notice of breach (or, at the Seller's election, the last day of the first
Monthly Period following such discovery), unless such breach shall have been
cured in all material respects, in the event of a breach of the representations
and warranties made by the Seller in Section 2.03 or Section 3.01, the Seller
shall repurchase, or in the event of a breach of a representation and warranty
under Section 4.01 of the Pooling and Administration Agreement the Seller and
the Trust Administrator shall use all reasonable efforts to enforce the
obligation of GMAC under Section 5.04 of the Pooling and Administration
Agreement to repurchase such COLT 2007-SN1 Secured Note from the Issuer on the
related Distribution Date. The repurchase price to be paid by the breaching
party (the "Warranty Purchaser") shall be an amount equal to the Warranty
Payment calculated as of the last day of the related Monthly Period and shall be
paid on such Distribution Date. It is understood and agreed that the obligation
of the Warranty Purchaser to repurchase any COLT 2007-SN1 Secured Note as to
which a breach has occurred and is continuing, and the obligation of the Seller
and the Trust Administrator to enforce GMAC's obligation to repurchase such COLT
2007-SN1 Secured Notes pursuant to the Pooling and Administration Agreement
shall, if such obligations are fulfilled, constitute the sole remedy against the
Seller, the Trust Administrator or GMAC for such breach available to the Issuer,
the Financial Parties, the CARAT Owner Trustee or the CARAT Indenture Trustee.
The Trust Administrator also acknowledges its obligations to repurchase
Administrative Secured Notes from the Issuer pursuant to Section 3.04 of the
Pooling and Administration Agreement.

     and the collateral security therefor, free of any Lien (other than tax
     liens and any other Liens that attach by operation of law).

          (ii) All Filings Made. All filings (including UCC filings) necessary
     in any jurisdiction to give the Issuer a first priority perfected ownership
     interest in the Second Step Purchased Property shall have been made.

merger, consolidation or succession pursuant to this Section 3.03 to the Rating
Agencies (if any Rated Notes are outstanding), the Servicer, the CARAT Indenture
Trustee and the CARAT Owner Trustee.

     (b) The Seller hereby agrees that during the term of this Agreement it
shall not (i) take any action prohibited by Article Fourth of its certificate of
incorporation (or any comparable provision in its certificate of formation,
limited liability company agreement or similar governing document), (ii) without
the prior written consent of the CARAT Indenture Trustee and the CARAT Owner
Trustee and without giving prior written notice to the Rating Agencies, amend
Article Third or Fourth of its certificate of incorporation (or any comparable
provision in its certificate of formation, limited liability company agreement
or similar governing document), or (iii) incur any indebtedness, issue any other
debt, or assume or guaranty indebtedness of any other entity, other than
pursuant to the Intercompany Note and the Intercompany Advance Agreement

     Section 3.04 Limitation on Liability of Seller and Others. The Seller and
any director or officer or employee or agent of the Seller may rely in good
faith on the advice of counsel or on any document of any kind prima facie
properly executed and submitted by any Person respecting any matters arising
under this Agreement and the Second Step Secured Notes Assignment. The Seller
and any director or officer or employee or agent of the Seller shall be
reimbursed by the CARAT Indenture Trustee or CARAT Owner Trustee, as applicable,
for any contractual damages, liability or expense incurred by reason of such
trustee's willful misfeasance, bad faith or negligence (except errors in
judgment) in the performance of its duties under this Agreement, the Second Step
Secured Notes Assignment, the CARAT Indenture or the Trust Agreement, or by
reason of reckless disregard of its obligations and duties under this Agreement,
the Second Step Secured Notes Assignment, the CARAT Indenture or the Trust
Agreement. In no event, however, shall the CARAT Indenture Trustee or the CARAT
Owner Trustee be liable to the Seller for any damages in the nature of special,
indirect or consequential damages, however styled, including lost profits, even
if either or both of them have been advised



of the likelihood of such loss or damage. The Seller shall not be under any
obligation to appear in, prosecute or defend any legal action that is not
incidental to its obligations as Seller of the COLT 2007-SN1 Secured Notes and
other Second Step Purchased Property under this Agreement and the Second Step
Secured Notes Assignment and that in its opinion may involve it in any expense
or liability.

     Section 3.05 Seller May Own CARAT 2007-SN1 Notes or CARAT 2007-SN1

under common control with the Seller may in its individual or any other capacity
become the owner or pledgee of CARAT 2007-SN1 Notes or CARAT 2007-SN1
Certificates with the same rights as it would have if it were not the Seller or
an Affiliate thereof, except as otherwise specifically provided herein. Except
as otherwise provided herein, CARAT 2007-SN1 Notes or CARAT 2007-SN1
Certificates so owned by or pledged to the Seller or such controlling or
commonly controlled Person shall have an equal and proportionate benefit under
the provisions of this Agreement, without preference, priority or distinction as
among all of such CARAT 2007-SN1 Notes or CARAT 2007-SN1 Certificates,
respectively.

     Section 4.03 Access to Certain Documentation and Information Regarding the
COLT 2007-SN1 Secured Notes. The Trust Administrator shall provide to the CARAT
Indenture Trustee and the CARAT Owner Trustee reasonable access to the
documentation regarding the COLT 2007-SN1 Secured Notes. The Trust Administrator
shall provide such access to any CARAT 2007-SN1 Noteholder or CARAT 2007-SN1
Certificateholder only in such cases where a CARAT 2007-SN1 Noteholder or a
CARAT 2007-SN1 Certificateholder is required by applicable statutes or
regulations to review such documentation. In each case, such access shall be
afforded without charge but only upon reasonable request and during normal
business hours at offices of the Trust Administrator designated by the Trust
Administrator. Nothing in this Section 4.03 shall derogate from the obligation
of the Trust Administrator to observe any applicable law prohibiting disclosure
of information regarding Lessees, and the failure of the Trust Administrator to
provide access as provided in this Section 4.03.

     Section 4.04 Assignment of Administrative Secured Notes and Warranty

Trust Administrator or the Warranty Purchaser, as applicable, all of such
Person's right, title and interest in, to and under such Administrative Secured
Note or Warranty Secured Note, the collateral therefor and the related rights
assigned thereunder. The Trust Administrator or the Warranty Purchaser, as

security and documents, free of any further obligations to the CARAT Indenture
Trustee, the CARAT Owner Trustee, the CARAT 2007-SN1 Noteholders or the CARAT
2007-SN1 Certificateholders with respect thereto. If in any Proceeding it is
held that the Trust Administrator may not enforce a COLT 2007-SN1 Secured Note
on the ground that it is not a real party in interest or a Holder entitled to
enforce the COLT 2007-SN1 Secured Note, the CARAT Indenture Trustee or the CARAT
Owner Trustee, as applicable, shall, at the Trust Administrator's expense, take
such steps as the Trust Administrator deems necessary to enforce the COLT
2007-SN1 Secured Note, including bringing suit in the name of such Person or the
names of the CARAT 2007-SN1 Noteholders or the CARAT 2007-SN1

     Basic Documents, and at the request of the CARAT Owner Trustee shall take
     all appropriate action that it is the duty of the Issuer or the CARAT Owner

     Owner Trustee, the Trust Administrator shall administer, perform or
     supervise the performance of such other activities in connection with the
     Collateral (including the CARAT Basic Documents) as are not covered by any

     Owner Trustee and are reasonably within the capability of the Trust
     Administrator.

          (ii) Notwithstanding anything in this Agreement or the CARAT Basic
     Documents to the contrary, the Trust Administrator shall be responsible for
     promptly notifying the CARAT Owner Trustee if any withholding tax is
     imposed on the Trust's payments to a CARAT 2007-SN1 Certificateholder as

     performance of the duties of the CARAT Owner Trustee set forth in Section
     5.4 of the Trust Agreement with respect to, among other things, accounting
     and reports to the CARAT 2007-SN1 Certificateholders; provided, however,
     that if the CARAT Owner Trustee is notified by the Trust Administrator that

          (vi) In carrying out the foregoing duties or any of its other
     obligations under this Agreement, the Trust Administrator may enter into
     transactions with or otherwise deal with any of its Affiliates; provided,
     however, that the terms of any such transactions or dealings shall be in
     accordance with any directions received from the Issuer and shall be, in

     would be available from Persons that are not Affiliates of the Trust
     Administrator.

          (i) With respect to matters described under this Section 4.08 that in

                                    ARTICLE V
           NOTEHOLDER ACCOUNTS; COLLECTIONS, DEPOSITS AND INVESTMENTS

     Section 5.01 Establishment of Accounts.

     (a) (i) The Trust Administrator, for the benefit of the Financial Parties,
shall establish and maintain in the name of the CARAT Indenture Trustee an
Eligible Deposit Account known as the Capital Auto Receivables Asset Trust
2007-SN1 Collection Account (the "CARAT Collection Account"), bearing an
additional designation clearly indicating that the funds deposited therein are
held in a segregated account for the benefit of the Financial Parties.

          (ii) The Trust Administrator, for the benefit of the CARAT 2007-SN1
     Noteholders, shall establish and maintain in the name of the CARAT
     Indenture Trustee an Eligible Deposit Account known as the Capital Auto
     Receivables Asset Trust 2007-SN1 Note Distribution Account (the "Note
     Distribution Account"), bearing an additional designation clearly
     indicating that the funds deposited therein are held in a segregated
     account for the benefit of the CARAT 2007-SN1 Noteholders.

     (b) (i) Each of the Designated Accounts shall be initially established with
the CARAT Indenture Trustee, who shall be the initial Account Holder. At any
time after the Series 2007-SN1 Closing Date, the Trust Administrator, upon 30
days prior written notice to the Account Holder, shall have the right to, and if
any Account Holder ceases to be an Eligible Institution the Trust Administrator
shall, instruct an Account Holder to transfer any or all of the Designated
Accounts to another Eligible Institution designated by the Trust Administrator
in such notice. No Designated Account shall be maintained with an Account Holder
if the short-term unsecured debt obligations of such Account Holder cease to
have the Required Deposit Rating (except that any Designated Account may be
maintained with an Account Holder even if the short-term unsecured debt
obligations of such Account Holder do not have the Required Deposit Rating, if
such Account Holder maintains such Designated Account as a segregated account in
its corporate trust department). Should an Account Holder no longer satisfy the
requirements in the preceding sentence with respect to any Designated Account,
then the Trust Administrator shall, within 10 Business Days (or such longer
period, not to exceed 30 calendar days, as to which each Rating Agency shall
consent), with the Account Holder's assistance as necessary, cause each affected
Designated Account (A) to be moved to an Account Holder that is an Eligible
Institution with the Required Deposit Rating or (B) to be moved to a segregated
account in the corporate trust department of the Account Holder. All amounts
held in such accounts shall, to the extent permitted by applicable laws, rules
and regulations, be invested, at the written direction of the Trust
Administrator, by such Account Holder in Eligible Investments. Such written
direction shall constitute certification by the Trust Administrator that any
such investment is authorized by this Section 5.01. In the absence of such prior
written instruction from the Trust Administrator to such Account Holder, the
Account Holder shall invest any uninvested funds in "BNY - Hamilton MMF Instit
#746." Investments in Eligible Investments shall be made in the name of the
CARAT Indenture Trustee or its nominee, and such investments shall not be sold
or disposed of prior to their maturity. Investment Earnings on funds deposited
in the Designated Accounts shall be payable to the Trust Administrator. Each
Account Holder holding a Designated Account as provided in this Section
5.01(b)(i), shall be a "Securities Intermediary." If a Securities Intermediary
shall be a Person other than the CARAT Indenture



Trustee, the Trust Administrator shall obtain the express agreement of such
Person to the obligations of the Securities Intermediary set forth in this
Section 5.01 and an Opinion of Counsel that such Person can perform such
obligations.

          (ii) With respect to the Designated Account Property, the Account
     Holder agrees, by its acceptance hereof, that:

               (A) Any Designated Account Property that is held in deposit
          accounts shall be held solely in Eligible Deposit Accounts. The
          Designated Accounts are accounts to which Financial Assets will be
          credited.

               (B) All securities or other property underlying any Financial
          Assets credited to the Designated Accounts shall be registered in the
          name of the Securities Intermediary, indorsed to the Securities
          Intermediary or in blank or credited to another securities account
          maintained in the name of the Securities Intermediary and in no case
          will any Financial Asset credited to any of the Designated Accounts be
          registered in the name of the Issuer, the Trust Administrator or the
          Seller, payable to the order of the Issuer, the Trust Administrator or
          the Seller or specially indorsed to the Issuer, the Trust
          Administrator or the Seller except to the extent the foregoing have
          been specially indorsed to the Securities Intermediary or in blank.

               (C) All property delivered to the Securities Intermediary
          pursuant to this Agreement will be credited upon receipt of such
          property to the appropriate Designated Account.

               (D) Each item of property (whether investments, investment
          property, Financial Asset, security, instrument or cash) credited to a
          Designated Account shall be treated as a "financial asset" within the
          meaning of Section 8-102(a)(9) of the New York UCC.

               (E) If at any time the Securities Intermediary shall receive any
          order from the CARAT Indenture Trustee directing transfer or
          redemption of any Financial Asset relating to the Designated Accounts,
          the Securities Intermediary shall comply with such order without
          further consent by the Trust, the Trust Administrator, the Seller or
          any other Person.

               (F) The Designated Accounts shall be governed by the laws of the
          State of New York, regardless of any provision in any other agreement.
          For purposes of the UCC, New York shall be deemed to be the Securities
          Intermediary's jurisdiction and the Designated Accounts (as well as
          the Security Entitlements related thereto) shall be governed by the
          laws of the State of New York.

               (G) The Securities Intermediary has not entered into, and until
          the termination of this Agreement will not enter into, any agreement
          with any other Person relating to the Designated Accounts and/or any
          Financial Assets or other property credited thereto pursuant to which
          it has agreed to comply with



          entitlement orders (as defined in Section 8-102(a)(8) of the New York
          UCC) of such other Person and the Securities Intermediary has not
          entered into, and until the termination of this Agreement will not
          enter into, any agreement with the Issuer, the Seller, the Trust
          Administrator, the Account Holder or the CARAT Indenture Trustee
          purporting to limit or condition the obligation of the Securities
          Intermediary to comply with entitlement orders as set forth in Section
          5.01(b)(ii)(E) hereof.

               (H) Except for the claims and interest of the CARAT Indenture
          Trustee in the Designated Accounts, the Securities Intermediary has no
          knowledge of claims to, or interests in, the Designated Accounts or in
          any Financial Asset credited thereto. If any other Person asserts any
          Lien (including any writ, garnishment, judgment, warrant of
          attachment, execution or similar process) against the Designated
          Accounts or in any Financial Asset carried therein, the Securities
          Intermediary will promptly notify the CARAT Indenture Trustee, the
          Trust Administrator and the Issuer thereof.

               (I) The Securities Intermediary will promptly send copies of all
          statements, confirmations and other correspondence concerning the
          Designated Accounts and/or any Designated Account Property
          simultaneously to each of the Trust Administrator and the CARAT
          Indenture Trustee, at the addresses set forth in Appendix B to this
          Agreement.

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

          (iii) The Trust Administrator shall have the power, revocable by the
     CARAT Indenture Trustee (or by the CARAT Owner Trustee with the consent of
     the CARAT Indenture Trustee), to instruct the CARAT Indenture Trustee to
     make withdrawals and payments from the Designated Accounts for the purpose
     of permitting the Trust Administrator or the CARAT Owner Trustee to carry
     out its respective duties hereunder or permitting the CARAT Indenture
     Trustee to carry out its duties under the CARAT Indenture.

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

          (v) The Trust Administrator shall not direct the Account Holder to
     make any investment of any funds or to sell any investment held in any of
     the Designated Accounts unless the security interest granted and perfected
     in such account shall continue to be perfected in such investment or the
     proceeds of such sale, in either case without any



     further action by any Person, and, in connection with any direction to the
     Account Holder to make any such investment or sale, if requested by the
     Account Holder, the Trust Administrator shall deliver to the Account Holder
     an Opinion of Counsel, acceptable to the Account Holder, to such effect.

     (c) Pursuant to the Trust Agreement, the Issuer 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 Investment
Earnings). Except as otherwise provided herein or in the Trust 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 Certificateholder.
If, at any time, the Certificate Distribution Account ceases to be an Eligible
Deposit Account, the CARAT Owner Trustee (or the Seller 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.

     (d) The CARAT Indenture Trustee, the CARAT Owner Trustee, the Securities
Intermediary, each Account Holder and each other Eligible Institution with whom
a Designated Account or the Certificate Distribution Account is maintained
waives any right of set-off, counterclaim, security interest or bankers' lien to
which it might otherwise be entitled.

     Section 5.02 Investment Earnings. The Trust Administrator shall be entitled
to receive all Investment Earnings when and as paid without any obligation to
the CARAT Owner Trustee, the CARAT Indenture Trustee or the Seller in respect
thereof, and the Trust Administrator shall have no obligation to deposit any
such amount in any account established hereunder. To the extent that any such
amount shall be held in any account held by the CARAT Indenture Trustee or the
CARAT Owner Trustee, or otherwise established hereunder, such amount will be
withdrawn therefrom and paid to the Trust Administrator upon presentation of a
certificate signed by a Responsible Officer of the Trust Administrator setting
forth, in reasonable detail, the amount of such Investment Earnings.

     Section 5.03 Additional Deposits. The Trust Administrator and the Seller
shall deposit in the CARAT Collection Account the aggregate Administrative
Purchase Payments and Warranty Payments with respect to Administrative Secured
Notes and Warranty Secured Notes, respectively. All such deposits with respect
to a Monthly Period shall be made in immediately available funds on or before
the Distribution Date related to such Monthly Period.

                                   ARTICLE VI
                  LIABILITIES OF TRUST ADMINISTRATOR AND OTHERS

          (ii) The Trust Administrator shall indemnify, defend and hold harmless
     the CARAT Indenture Trustee, the CARAT Owner Trustee and the Issuer from
     and against any taxes that may at any time be asserted against any such
     Person with respect to the transaction contemplated in this Agreement,
     including any sales, gross receipts, general corporation, tangible personal
     property, privilege or license taxes (but not including any taxes asserted
     with respect to, and as of the date of, the sale of the COLT 2007-SN1
     Secured Notes to the Issuer or the issuance and original sale of the CARAT
     2007-SN1 Notes and the CARAT 2007-SN1 Certificates, or asserted with

     cost, expense, loss, claim, damage, or liability arose out of, or was
     imposed upon the CARAT Indenture Trustee, the CARAT Owner Trustee, the
     Issuer, the CARAT 2007-SN1 Noteholders or the CARAT 2007-SN1
     Certificateholders through the negligence, willful misfeasance or bad faith
     of the Trust Administrator in the performance of its duties under any CARAT
     Basic Document or by reason of reckless disregard of its obligations and
     duties under any CARAT Basic Document; and

          (iv) The Trust Administrator shall indemnify, defend and hold harmless
     the CARAT Indenture Trustee and the CARAT Owner Trustee, and their
     respective agents and servants, from and against all costs, expenses,
     losses, claims, damages and liabilities arising out of or incurred in

     any other CARAT Basic Document, (y) in the case of the CARAT Indenture

     Trustee, as applicable, of the trusts and duties contained in this
     Agreement, the other CARAT Basic Documents, the CARAT Indenture (in the

     CARAT Trust Estate, and the Trust Agreement (in case of the CARAT Owner
     Trustee), including the administration of the CARAT Owner Trust



     Estate, except in each case to the extent that such cost, expense, loss,
     claim, damage or liability: (A) is due to the willful misfeasance, bad
     faith or negligence (except for errors in judgment) of the Person
     indemnified, (B) to the extent otherwise payable to the CARAT Indenture
     Trustee, arises from the CARAT Indenture Trustee's breach of any of its
     representations or warranties in Section 6.12 of the CARAT Indenture, (C)
     to the extent otherwise payable to the CARAT Owner Trustee, arises from the
     CARAT Owner Trustee's breach of any of its representations or warranties
     set forth in Section 6.6 of the Trust Agreement, or (D) shall arise out of
     or be incurred in connection with the performance by the CARAT Indenture
     Trustee of the duties of successor Trust Administrator hereunder.

     (b) Indemnification under this Section 6.01 shall include reasonable fees
and expenses of external counsel and expenses of litigation. If the Trust
Administrator has made any indemnity payments pursuant to this Section 6.01 and
the recipient thereafter collects any of such amounts from others, the recipient
shall promptly repay such amounts collected to the Trust Administrator, without
interest.

     Section 6.02 Merger or Consolidation of, or Assumption of the Obligations
of the Trust Administrator. Any corporation or other entity

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

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

     (c) succeeding to the business of the Trust Administrator,

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

which entity in any of the foregoing cases executes an agreement of assumption
to perform every obligation of the Trust Administrator under this Agreement and
the Further Transfer and Administration Agreements, shall be the successor to
the Trust Administrator under this Agreement without the execution or filing of
any paper or any further act on the part of any of the parties to this
Agreement, anything in this Agreement, to the contrary notwithstanding. The
Trust Administrator shall provide notice of any merger, consolidation or
succession pursuant to this Section 6.02 to the CARAT Indenture Trustee, the
CARAT Owner Trustee and, if any Rated Notes are outstanding, the Rating
Agencies.

     Section 6.03 Limitation on Liability of Trust Administrator and Others.

     (a) Neither the Trust Administrator nor any of the directors or officers or
employees or agents of the Trust Administrator shall be under any liability to
the Issuer, the CARAT 2007-SN1 Noteholders or the CARAT 2007-SN1
Certificateholders, except as specifically provided in this Agreement and in the
Pooling and Administration Agreement, for any action taken or for refraining
from the taking of any action pursuant to this Agreement, the Pooling and
Administration Agreement, the CARAT Indenture or the Trust Agreement or for
errors in



judgment; provided, however, that this provision shall not protect the Trust
Administrator or any such Person against any liability that would otherwise be
imposed by reason of willful misfeasance, bad faith or negligence (except errors
in judgment) in the performance of duties or by reason of reckless disregard of
obligations and duties under this Agreement, the Pooling and Administration
Agreement, the CARAT Indenture, the Trust Agreement or any other CARAT Basic
Document. The Trust Administrator and any director, officer or employee or agent
of the Trust Administrator may rely in good faith on the advice of counsel or on
any document of any kind prima facie properly executed and submitted by any
Person respecting any matters arising under this Agreement or the Pooling and
Administration Agreement.

     (b) The Trust Administrator and any director or officer or employee or
agent of the Trust Administrator shall be reimbursed by the CARAT Indenture
Trustee or the CARAT Owner Trustee, as applicable, for any contractual damages,
liability or expense (including any obligation of the Trust Administrator to the
CARAT Indenture Trustee or the CARAT Owner Trustee, as applicable, pursuant to
Section 6.01(a)(iv)(x) or (y)) incurred by reason of such trustee's willful
misfeasance, bad faith or negligence (except errors in judgment) in the
performance of such trustee's duties under this Agreement, the CARAT Indenture
or the Trust Agreement or by reason of reckless disregard of its obligations and
duties under this Agreement. In no event, however, shall the CARAT Indenture
Trustee or the CARAT Owner Trustee be liable to the Trust Administrator for any
damages in the nature of special, indirect or consequential damages, however
styled, including lost profits, even if either or both of them have been advised
of the likelihood of such loss or damage.

     (c) Except as provided in this Agreement or in the Pooling and
Administration Agreement, the Trust Administrator shall not be under any
obligation to appear in, prosecute or defend any legal action that is not
incidental to its duties to administer the COLT 2007-SN1 Secured Notes in
accordance with this Agreement and the Pooling and Administration Agreement and
that in its opinion may involve it in any expense or liability; provided,
however, that the Trust Administrator may undertake any reasonable action that
it may deem necessary or desirable in respect of this Agreement or the Pooling
and Administration Agreement and the rights and duties of the parties to this
Agreement or the Pooling and Administration Agreement and the interests of the
CARAT 2007-SN1 Noteholders and CARAT 2007-SN1 Certificateholders under this
Agreement and the Pooling and Administration Agreement, the interests of the
CARAT 2007-SN1 Noteholders under the CARAT Indenture and the interests of the
CARAT 2007-SN1 Certificateholders under the Trust Agreement. In such event, the
legal expenses and costs invoiced for such action and any liability resulting
therefrom shall be expenses, costs and liabilities of the Trust and the Trust
Administrator shall be entitled to be reimbursed therefor.

     (d) The CARAT Trustee shall distribute out of the CARAT Collection Account
on a Distribution Date any amounts permitted for reimbursement pursuant to
Section 6.03(c) not previously reimbursed.

     Section 6.04 Delegation of Duties. So long as GMAC acts as Trust
Administrator, the Trust Administrator may, at any time without notice or
consent, delegate any duties under this Agreement or under the Pooling and
Administration Agreement to any corporation or other Person more than 50% of the
voting stock (or, if not a corporation, other voting interests) of



which is owned, directly or indirectly, by General Motors or GMAC. The Trust
Administrator may at any time perform specific duties as Trust Administrator
through sub-contractors who are in the business of servicing automotive
receivables. No such delegation or sub-contracting shall relieve the Trust
Administrator of its responsibility with respect to such duties.

     Section 6.05 Trust Administrator Not to Resign. Subject to the provisions
of Section 7.02, the Trust Administrator shall not resign from the obligations
and duties imposed on it by this Agreement and the Pooling and Administration
Agreement as Trust Administrator except upon determination that the performance
of its duties under this Agreement or under the Pooling and Administration
Agreement, as the case may be, is no longer permissible under applicable law.
Any such determination permitting the resignation of the Trust Administrator
shall be evidenced by an Opinion of Counsel to such effect delivered to the
CARAT Indenture Trustee and the CARAT Owner Trustee. No such resignation shall
become effective until the CARAT Indenture Trustee or a successor Trust
Administrator shall have assumed the responsibilities and obligations of the
Trust Administrator in accordance with Section 7.02.

                                  ARTICLE VII
                                    DEFAULT

     Section 7.01 Trust Administrator Defaults. Each of the following shall
constitute a "Trust Administrator Default":

     (a) any failure by the Trust Administrator to deliver to the CARAT
Indenture Trustee for deposit in any of the Designated Accounts any required
payment or to direct the CARAT Indenture Trustee to make any required
distributions therefrom, which failure continues unremedied for a period of five
Business Days after (x) written notice thereof is received by the Trust
Administrator from the CARAT Indenture Trustee or the CARAT Owner Trustee or (y)
discovery of such failure by an officer of the Trust Administrator;

     (b) any failure on the part of the Seller or the Trust Administrator to
duly observe or perform in any material respect any other covenants or
agreements of the Seller or the Trust Administrator set forth in this Agreement,
the Pooling and Administration Agreement, the CARAT Indenture or the Trust
Agreement which failure (i) materially and adversely affects the rights of CARAT
2007-SN1 Noteholders or CARAT 2007-SN1 Certificateholders, and (ii) continues
unremedied for a period of 90 days after the date on which written notice of
such failure, requiring the same to be remedied, shall have been given to the
Seller or the Trust Administrator, as applicable, by the CARAT Indenture Trustee
or the CARAT Owner Trustee, or to the Seller or the Trust Administrator, as
applicable, and to the CARAT Indenture Trustee or the CARAT Owner Trustee by
CARAT Noteholders whose CARAT 2007-SN1 Notes evidence less than 25% of the
Outstanding Amount of the Controlling Class as of the close of the preceding
Distribution Date or by CARAT 2007-SN1 Certificateholders whose CARAT 2007-SN1
Certificates evidence not less than 25% of the Voting Interests as of the close
of the preceding Distribution Date;

     (c) the entry of a decree or order by a court or agency or supervisory
authority having jurisdiction in the premises for the appointment of a
conservator, receiver or liquidator for the Seller or the Trust Administrator,
in any insolvency, readjustment of debt, marshalling of assets



and liabilities or similar proceedings, or for the winding up or liquidation of
their respective affairs, and the continuance of any such decree or order
unstayed and in effect for a period of 90 consecutive days; or

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

Notwithstanding the foregoing, there shall be no Trust Administrator Default
where a Trust Administrator Default would otherwise exist under clause (a) above
for a period of ten Business Days or under clause (b) for a period of 60 days if
the delay or failure giving rise to the Trust Administrator Default was caused
by an act of God or other similar occurrence. Upon the occurrence of any of
those events, the Trust Administrator shall not be relieved from using its best
efforts to perform its obligations in a timely manner in accordance with the
terms of the Pooling and Administration Agreement and this Agreement and the
Trust Administrator shall provide the CARAT Indenture Trustee, the CARAT Owner
Trustee, the Seller and the Securityholders prompt notice of the failure or
delay by it, together with a description of its efforts to so perform its
obligations.

     Section 7.02 Consequences of a Trust Administrator Default. If a Trust
Administrator Default shall occur and be continuing, either the CARAT Indenture
Trustee or the CARAT 2007-SN1 Noteholders whose CARAT 2007-SN1 Notes evidence
not less than a majority of the Outstanding Amount of the Controlling Class as
of the close of the preceding Distribution Date (or if the CARAT 2007-SN1 Notes
have been paid in full and the CARAT Indenture has been discharged in accordance
with its terms, by the CARAT Owner Trustee or 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) by notice
then given in writing to the Trust Administrator and the CARAT Owner Trustee
(and to the CARAT Indenture Trustee if given by the CARAT 2007-SN1 Noteholders
or the CARAT 2007-SN1 Certificateholders) may terminate all of the rights and
obligations of the Trust Administrator under this Agreement and the Pooling and
Administration Agreement. On or after the receipt by the Trust Administrator of
such written notice, all authority and power of the Trust Administrator under
this Agreement and the Pooling and Administration Agreement, whether with
respect to the CARAT 2007-SN1 Notes, the CARAT 2007-SN1 Certificates or the COLT
2007-SN1 Secured Notes or otherwise, shall pass to and be vested in the
Indenture Trustee pursuant to and under this Section 7.02. The CARAT Indenture
Trustee is hereby authorized and empowered to execute and deliver, on behalf of
the Trust Administrator, as attorney-in-fact or otherwise, any and all documents
and other instruments, and to do or accomplish all other acts or things
necessary or appropriate to effect the purposes of such notice of termination,
whether to complete the transfer and endorsement of the COLT 2007-SN1 Secured
Notes and related documents, or otherwise. The Trust Administrator agrees to
cooperate with the CARAT Indenture Trustee and the CARAT Owner Trustee in
effecting the termination of the responsibilities and rights of the Trust
Administrator under this Agreement and the Pooling and



Administration Agreement, including the transfer to the CARAT Indenture Trustee
or the CARAT Owner Trustee for administration by it of all cash amounts that
shall at the time be held by the Trust Administrator for deposit, or that shall
have been deposited by the Trust Administrator in the CARAT Collection Account,
the Note Distribution Account or the Certificate Distribution Account or
thereafter received with respect to the COLT 2007-SN1 Secured Notes that shall
at that time be held by the Trust Administrator.

     Section 7.03 CARAT Indenture Trustee to Act; Appointment of Successor. On
and after the time the Trust Administrator receives a notice of termination
pursuant to Section 7.02, the CARAT Indenture Trustee shall be the successor in
all respects to the Trust Administrator in its capacity as Trust Administrator
under this Agreement and the Pooling and Administration Agreement and the
transactions set forth or provided for in this Agreement and the Pooling and
Administration Agreement and shall be subject to all the responsibilities,
restrictions, duties and liabilities relating thereto placed on the Trust
Administrator by the terms and provisions of this Agreement and the Pooling and
Administration Agreement. As compensation therefor, the CARAT Indenture Trustee
shall be entitled to such compensation (whether payable out of the CARAT
Collection Account or otherwise) as the Trust Administrator would have been
entitled to under this Agreement if no such notice of termination had been given
including the Administration Fee and Investment Earnings. Notwithstanding the
above, the CARAT Indenture Trustee may, if it shall be unwilling so to act, or
shall, if it is legally unable so to act, appoint, or petition a court of
competent jurisdiction to appoint, a successor (i) having a net worth of not
less than $100,000,000, (ii) a long-term unsecured debt rating from Moody's of
at least "Baa3" (unless such requirement is expressly waived by Moody's), and
(iii) whose regular business includes the servicing of automotive loans, leases
or similar notes or receivables, as the successor to the Trust Administrator
under this Agreement and the Pooling and Administration Agreement in the
assumption of all or any part of the responsibilities, duties or liabilities of
the Trust Administrator under this Agreement and the Pooling and Administration
Agreement. In connection with such appointment and assumption, the CARAT
Indenture Trustee may make such arrangements for the compensation of such
successor out of payments on COLT 2007-SN1 Secured Notes as it and such
successor shall agree; provided, however, that no such compensation shall be in
excess of that permitted the Trust Administrator under this Agreement and the
Pooling and Administration Agreement. The CARAT Indenture Trustee and such
successor shall take such action, consistent with this Agreement and the Pooling
and Administration Agreement, as shall be necessary to effectuate any such
succession. Costs associated with the resignation of the Trust Administrator and
the appointment of a successor Trust Administrator shall be distributed by the
CARAT Indenture Trustee from amounts in the CARAT Trust Estate.

     Section 7.04 Notification to CARAT 2007-SN1 Noteholders and CARAT 2007-SN1
Certificateholders. Upon any termination of, or appointment of a successor to,
the Trust Administrator pursuant to this Article VII, the CARAT Indenture
Trustee shall give prompt written notice thereof to the CARAT 2007-SN1
Noteholders and the Rating Agencies, and the CARAT Owner Trustee shall give
prompt written notice thereof to the CARAT 2007-SN1 Certificateholders.

     Section 7.05 Waiver of Past Defaults. Noteholders whose CARAT 2007-SN1
Notes evidence not less than a majority of the Outstanding Amount of the
Controlling Class as of the



close of the preceding Distribution Date (or, if all of the Notes have been paid
in full and the CARAT Indenture has been discharged in accordance with its
terms), 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) may, on behalf of all CARAT 2007-SN1 Noteholders
and CARAT 2007-SN1 Certificateholders, waive any default by the Trust
Administrator in the performance of its obligations hereunder and its
consequences, except a default in making any required deposits to or payments
from any of the accounts in accordance with this Agreement. Upon any such waiver
of a past default, such default shall cease to exist, and any Trust
Administrator Default arising therefrom shall be deemed to have been remedied
for every purpose of this Agreement and the Pooling and Administration
Agreement. No such waiver shall extend to any subsequent or other default or
impair any right consequent thereon.

                                  ARTICLE VIII
                                   TERMINATION

     Section 8.01 Optional Purchase of All COLT 2007-SN1 Secured Notes;
Insolvency of Seller; Termination of Trust.

     (a) (i) The Seller shall have the option to purchase all but not less than
all of the assets of the Trust (other than the Designated Accounts and the
Certificate Account) on any Distribution Date (the "Optional Purchase Date")
following the last day of any Monthly Period as of which the Aggregate ABS Value
represents a percentage of the Aggregate Initial ABS Value that is equal to or
less than the Optional Purchase Percentage. To exercise such option, the Seller
shall (A) furnish to the Issuer and the CARAT Indenture Trustee notice of its
intention to exercise such option and of the Optional Purchase Date (such notice
to be furnished not later than 25 days prior to the Optional Purchase Date) and
(B) deposit in the CARAT Collection Account when required pursuant to clause
(ii) below an amount equal to the aggregate Administrative Purchase Payments for
the COLT 2007-SN1 Secured Notes, plus the appraised value of any other property
held by the Trust, provided, that such amount (when added to any funds then on
deposit in the Designated Accounts and the Certificate Distribution Account)
must be at least equal to the sum of (1) the Administration Fee for the related
Monthly Period, (2) the aggregate Redemption Price of all then Outstanding
Notes, and (3) any amounts payable to the Swap Counterparty under any Interest
Rate Swap. Such appraised value shall be determined by an appraiser mutually
satisfactory to the Seller, the CARAT Owner Trustee and the CARAT Indenture
Trustee.

          (ii) The Seller shall make the deposit set forth in clause (i)(B)
     above in immediately available funds on the Optional Purchase Date. Upon
     the making of such deposit, the CARAT 2007-SN1 Notes and the CARAT
     Indenture shall be deemed satisfied and discharged, and the Seller shall
     succeed to all interests in and to the Trust (other than the Designated
     Accounts and the rights of the Trust under the Interest Rate Swaps).

     (b) Upon any sale or other disposition of the assets of the Trust pursuant
to Article V of the CARAT Indenture (an "CARAT Event of Default Sale"), the
Trust Administrator shall instruct the Applicable CARAT Trustee to deposit into
the CARAT Collection Account from the proceeds of such disposition the amount
specified in clause SECOND of Section 5.4(b) of the



CARAT Indenture (the "CARAT Event of Default Proceeds"). On the Distribution
Date (i) on which the CARAT Event of Default Proceeds are deposited in the CARAT
Collection Account (or, if such proceeds are not so deposited on a Distribution
Date, on the Distribution Date immediately following such deposit), or (ii) at
any time that the CARAT 2007-SN1 Notes have not been paid in full and the
principal balance of the CARAT 2007-SN1 Notes has been declared immediately due
and payable following the occurrence of a CARAT Event of Default under the CARAT
Indenture, then until such time as the CARAT 2007-SN1 Notes have been paid in
full and the CARAT Indenture has been discharged or the foregoing Events of
Default have been cured or waived as provided in Section 5.2(b) of the CARAT
Indenture, the Trust Administrator shall instruct the CARAT Indenture Trustee
(after taking into account the application on such Distribution Date of the
Total Available Amount pursuant to Section 4.05(a)) to make the following
distributions from the CARAT Collection Account in the following priority:

          (i) first, to the Trust Administrator, the Administration Fee for such
     Distribution Date and any unpaid Administration Fee from any preceding
     Distribution Date;

          (ii) second, to the Swap Counterparty, the net amount, if any, then
     due to the Swap Counterparty under all Interest Rate Swaps (exclusive of
     payments due to the Swap Counterparty in respect of an Early Termination
     Date under such Interest Rate Swaps);

          (iii) third, to (a) the Note Distribution Account, for payment of
     interest pro rata on the Class A Notes, the Aggregate Class A Interest
     Distributable Amount and (b) to the Swap Counterparty in respect of any
     payments due to the Swap Counterparty in connection with any Early
     Termination Date of any Interest Rate Swaps related to the Class A-2b Notes
     or the Class A-4b Notes allocated between the Note Distribution Account and
     the Swap Counterparty in proportion to the amounts owing in respect of the
     Aggregate Class A Interest Distributable Amount and the amounts owing to
     the Swap Counterparty in connection with such Early Termination Date;

          (iv) fourth, to the Note Distribution Account, an amount equal to the
     Note Principal Balance of the Class A Notes (after giving effect to the

                         PART II - RULES OF CONSTRUCTION

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

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

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

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

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