such reasonable regulations as the Issuer may prescribe, the Issuer shall
provide for the registration of the CARAT 2007-SN1 Notes and the registration of

the Issuer as Note Registrar, the Issuer will give the CARAT Indenture Trustee
prompt written notice of the appointment of such Note Registrar and of the
location, and any change in the location, of the Note Register. The CARAT
Indenture Trustee shall have the right to inspect the Note Register at all
reasonable times and to obtain copies thereof. The CARAT Indenture Trustee shall
have the right to rely upon a certificate executed on behalf of the Note
Registrar by an Executive Officer thereof as to the names and addresses of the
CARAT 2007-SN1 Noteholders and the principal amounts and number of such CARAT
2007-SN1 Notes.

          (c) Upon surrender for registration of transfer of any CARAT 2007-SN1
Note at the Corporate Trust Office of the CARAT Indenture Trustee or the Agency
Office of the Issuer (and following the delivery, in the former case, of such
CARAT 2007-SN1 Notes to the Issuer by the CARAT Indenture Trustee), the Issuer
shall execute, the CARAT Indenture Trustee shall authenticate and the CARAT
2007-SN1 Noteholder shall obtain from the CARAT Indenture Trustee, in the name

          (d) At the option of a CARAT 2007-SN1 Noteholder, CARAT 2007-SN1 Notes
may be exchanged for other CARAT 2007-SN1 Notes of the same class in any
authorized denominations, of a like aggregate principal amount, upon surrender
of such CARAT 2007-SN1 Notes to be exchanged at the Corporate Trust Office of
the CARAT Indenture Trustee or the Agency Office of the Issuer (and following
the delivery, in the former case, of such CARAT 2007-SN1 Notes to the Issuer by

the CARAT Indenture Trustee, such CARAT 2007-SN1 Notes which the CARAT 2007-SN1
Noteholder making the exchange is entitled to receive. (e) All CARAT 2007-SN1
Notes issued upon any registration of transfer or exchange of other CARAT
2007-SN1 Notes shall be the valid obligations of the Issuer, evidencing the same
debt, and entitled to the same benefits under this CARAT Indenture, as the CARAT
2007-SN1 Notes surrendered upon such registration of transfer or exchange.

          (f) Every CARAT 2007-SN1 Note presented or surrendered for
registration of transfer or exchange shall be duly endorsed by, or be
accompanied by a written instrument of


                                        5

York or the city in which the Corporate Trust Office of the CARAT Indenture
Trustee is located, or by a member firm of a national securities exchange, and
such other documents as the CARAT Indenture Trustee may require.

          (g) No service charge shall be made to a Holder for any registration
of transfer or exchange of CARAT 2007-SN1 Notes, but the Issuer or CARAT
Indenture Trustee may require payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in connection with any
registration of transfer or exchange of CARAT 2007-SN1 Notes, other than
exchanges pursuant to Sections 2.3 or 9.6 not involving any transfer.

Benefit Plan or other plan subject to applicable law that is substantially
similar to Section 406 of ERISA or Section 4975 of the Code or (b) the
acquisition and holding of the CARAT 2007-SN1 Note will not give rise to a
non-exempt prohibited transaction under Section 406(a) of ERISA, Section 4975 of

(ii) there is delivered to the CARAT Indenture Trustee such security or
indemnity as may be required by it to hold the Issuer and the CARAT Indenture
Trustee harmless, then, in the absence of notice to the Issuer, the Note
Registrar or the CARAT Indenture Trustee that such CARAT 2007-SN1 Note has been
acquired by a Protected Purchaser, the Issuer shall execute and upon the
Issuer's request the CARAT Indenture Trustee shall authenticate and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen CARAT
2007-SN1 Note, a replacement CARAT 2007-SN1 Note of a like class and aggregate

when so due or payable or upon the Redemption Date, if applicable, without
surrender thereof.

Trustee shall be entitled to recover such replacement CARAT 2007-SN1 Note (or
such payment) from (i) any Person to whom it was delivered, (ii) the Person
taking such replacement CARAT 2007-SN1 Note from the Person to whom such
replacement CARAT 2007-SN1 Note was delivered; or (iii) any assignee of such
Person, except a Protected Purchaser, and the Issuer and the CARAT Indenture
Trustee 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
Issuer or the CARAT Indenture Trustee in connection therewith.

          (c) In connection with the issuance of any replacement CARAT 2007-SN1
Note under this Section 2.5, the Issuer may require the payment by the Holder of
such CARAT 2007-SN1 Note 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 all fees and expenses of the CARAT Indenture
Trustee) connected therewith.

          (d) Any duplicate CARAT 2007-SN1 Note issued pursuant to this Section
2.5 in replacement for any mutilated, destroyed, lost or stolen CARAT 2007-SN1

Note shall be found at any time or be enforced by any Person, and shall be
entitled to all the benefits of this CARAT Indenture equally and proportionately
with any and all other CARAT 2007-SN1 Notes duly issued hereunder.

          (e) The provisions of this Section 2.5 are exclusive and shall

2007-SN1 Notes.

     Section 2.6 Persons Deemed CARAT 2007-SN1 Noteholders. Prior to due

payments of principal of and interest on such CARAT 2007-SN1 Notes to such
Clearing Agency Participants, pursuant to the Note Depository Agreement; and

          (e) whenever this CARAT Indenture requires or permits actions to be
taken based upon instructions or directions of Holders of CARAT 2007-SN1 Notes
evidencing a specified percentage of the Outstanding Amount of the Controlling
Class, the Clearing Agency shall be deemed to represent such percentage only to
the extent that (i) it has received instructions to such effect from Note Owners
and/or Clearing Agency Participants owning or representing, respectively, such
required percentage of the beneficial interest in the CARAT 2007-SN1 Notes; or
(ii) the CARAT Indenture Trustee has received such direction from the Note
Owners directly.

     Section 2.11 Notices to Clearing Agency. Whenever a notice or other
communication to the CARAT 2007-SN1 Noteholders is required under this CARAT
Indenture, unless and until Definitive Notes shall have been issued to Note
Owners pursuant to Section 2.12, the CARAT Indenture Trustee shall give all such
notices and communications specified herein to be given to CARAT 2007-SN1
Noteholders to the Clearing Agency and shall have no other obligation to the
Note Owners.

     Section 2.12 Definitive Notes. If (i) the Trust Administrator advises the
CARAT Indenture Trustee in writing that the Clearing Agency is no longer willing
or able to properly discharge its responsibilities with respect to the Notes and
the Issuer is unable to locate a qualified successor; (ii) the Trust
Administrator, at its option, advises the CARAT Indenture Trustee in writing
that it elects to terminate the book-entry system through the Clearing Agency;
or (iii) after the occurrence of a CARAT Event of Default or a Trust
Administrator Default, Note Owners representing beneficial interests aggregating
at least a majority of the Outstanding Amount of the Controlling Class advise
the Clearing Agency in writing that the continuation of a book-entry system
through the Clearing Agency is no longer in the best interests of the Note
Owners, then the Clearing Agency shall notify all Note Owners and the CARAT
Indenture Trustee of the occurrence of any such event and of the availability of
Definitive Notes to Note Owners requesting the same. Upon surrender to the CARAT
Indenture Trustee of the typewritten CARAT 2007-SN1 Note or CARAT 2007-SN1 Notes
representing the Book-Entry Notes by the Clearing Agency, accompanied by
registration instructions, the Issuer shall execute and the CARAT Indenture
Trustee shall authenticate the Definitive Notes in accordance with the
instructions of the Clearing Agency. None of the Issuer, the Note Registrar or
the CARAT Indenture Trustee shall be liable for any delay in delivery of such
instructions and may conclusively rely on, and shall be protected in relying on,
such instructions. Upon the issuance of Definitive Notes, the CARAT Indenture
Trustee shall recognize the Holders of the Definitive Notes as CARAT 2007-SN1
Noteholders.

     Section 2.13 Seller as CARAT 2007-SN1 Noteholder. The Seller in its
individual or any other capacity may become the owner or pledgee of CARAT
2007-SN1 Notes of any class


                                       11

and may otherwise deal with the Issuer or its affiliates with the same rights it
would have if it were not the Seller.

     Section 2.14 Tax Treatment. The Seller and the CARAT Indenture Trustee, by
entering into this CARAT Indenture, and the CARAT 2007-SN1 Noteholders, by
acquiring any CARAT 2007-SN1 Note or interest therein, (i) express their
intention that the CARAT 2007-SN1 Notes qualify under applicable tax law as
indebtedness secured by the Collateral, and (ii) unless otherwise required by
appropriate taxing authorities, agree to treat the CARAT 2007-SN1 Notes as
indebtedness secured by the Collateral for the purpose of federal income taxes,
State and local income and franchise taxes, Michigan single business tax, and
any other taxes imposed upon, measured by or based upon gross or net income.

     Section 2.15 Special Terms Applicable to Class A-1 Notes; Transfer of
Beneficial Interest in Class A-1 Notes.

          (a) None of the Class A-1 Notes have been or will be registered under
the Securities Act or the securities laws of any other jurisdiction.
Consequently, the Class A-1 Notes are not transferable other than pursuant to an
exemption from the registration requirements of the Securities Act and
satisfaction of certain other provisions specified herein. The Class A-1 Notes
or any interest therein are being sold in one or more private placements on the
date hereof.

          (b) Thereafter, no further sale, pledge or other transfer of any Class
A-1 Note (or interest therein) may be made by any Person unless either (A) such
sale, pledge or other transfer is made to a "qualified institutional buyer" as
defined under Rule 144A under the Securities Act that delivers any necessary
certifications pursuant to Section 2.15(d) or (e) and that (1) is a "qualified
institutional buyer" as defined under Rule 144A under the Securities Act, acting
for its own account or the accounts of other "qualified institutional buyers" as
defined under Rule 144A under the Securities Act, and (2) it is aware that the
transferor of such Class A-1 Notes intends to rely on the exemption from the
registration requirements of the Securities Act provided by Rule 144A under the
Securities Act, (B) such sale, pledge or other transfer occurs outside of the
United States to a non-U.S. Person in accordance with Rule 903 or Rule 904 of
Regulation S of the Securities Act and that Person delivers any necessary
certifications pursuant to Section 2.15(d) or (e), or (C) if the Class A-1 Notes
are no longer eligible for resale pursuant to Rule 144A or Regulation S of the
Securities Act, such sale, pledge or other transfer is made in a transaction
otherwise exempt from the registration requirements of the Securities Act, in
which case (1) the CARAT Indenture Trustee shall require that both the
prospective transferor and the prospective transferee certify to the CARAT
Indenture Trustee and the Seller in writing the facts surrounding such transfer,
which certification shall be in form and substance satisfactory to the CARAT
Indenture Trustee and the Seller, and (2) the CARAT Indenture Trustee shall
require a written opinion of counsel (which will not be at the expense of the
Seller, the Trust Administrator or the CARAT Indenture Trustee) satisfactory to
the Seller and the CARAT Indenture Trustee to the effect that such transfer will
not violate the Securities Act.

          Neither the Seller nor the CARAT Indenture Trustee will register any
of the Class A-1 Notes under the Securities Act, qualify any of the Class A-1
Notes under the securities laws of any State or provide registration rights to
any purchaser or Holder thereof.


                                       12

<PAGE>

          (c) Each Class A-1 Note shall bear a legend to the effect set forth in
Section 2.15(b) above.

          (d) If a transfer of a beneficial interest held by the related
transferor in the form of a Rule 144A Global Class A-1 Note to be held by the
related transferee in the form of a Rule 144A Global Class A-1 Note is to be
made without registration under the Securities Act (other than in connection
with the initial issuance thereof or a transfer thereof by the Seller or one of
its Affiliates), then the Note Registrar shall refuse to register such transfer
unless it receives (and upon receipt, may conclusively rely upon) a certificate
from the CARAT 2007-SN1 Noteholder desiring to effect such transfer
substantially in the form attached as Exhibit D-1 hereto and a certificate from
such CARAT 2007-SN1 Noteholder's prospective transferee substantially in the
form attached as Exhibit D-2 hereto. If a transfer of a beneficial interest held
by the related transferor in the form of a Rule 144A Global Class A-1 Note to be
held by the related transferee in the form of a Temporary Regulation S Global
Class A-1 Note, on or prior to the Exchange Date, or a Permanent Regulation S
Global Class A-1 Note, after the Exchange Date, is to be made without
registration under the Securities Act, then the Note Registrar shall refuse to
register such transfer unless it receives (and upon receipt may conclusively
rely upon) a certificate substantially in the form of Exhibit D-3 hereto (a
"Regulation S Transfer Certificate") from the CARAT 2007-SN1 Noteholder desiring
to effect such transfer or such other certification reasonably acceptable to the
Seller and the Note Registrar, in either case to the effect that such transfer
is being made in accordance with Rule 903 or Rule 904 of Regulation S and that,
if such transfer occurs on or prior to the Exchange Date, the interest
transferred will be held immediately thereafter through Euroclear or
Clearstream.

          (e) If any transfer of a beneficial interest held by the related
transferor in the form of a Temporary Regulation S Global Class A-1 Notes or a
Permanent Regulation S Global Class A-1 Note is to be made without registration
under the Securities Act, then the Note Registrar shall refuse to register such
transfer unless it receives (and upon receipt may conclusively rely upon) (i) in
the case of a transfer to a transferee that takes delivery in the form of a
beneficial interest in a Rule 144A Global Class A-1 Note, a certificate from the
CARAT 2007-SN1 Noteholder desiring to effect such transfer substantially in the
form of Exhibit D-4 hereto (a "Rule 144A Transfer Certificate") or such other
certification reasonably acceptable to the Seller and the Note Registrar; and
(ii) in the case of a transferee that takes delivery, in the form of a
beneficial interest in a Temporary Regulation S Global Class A-1 Note, on or
prior to the Exchange Date, or a Permanent Regulation S Global Class A-1 Note,
after the Exchange Date, a Regulation S Transfer Certificate from the CARAT
2007-SN1 Noteholder desiring to effect such transfer or such other certification
reasonably acceptable to the Seller and the Note Registrar, in either case to
the effect that such transfer is being made in accordance with Rule 903 or 904
of Regulation S and that, if such transfer occurs on or prior to the Exchange
Date, the interest transferred will be held immediately thereafter through
Euroclear or Clearstream. A beneficial interest in the Class A-1 Notes held by
the related transferor in the form of a Temporary Regulation S Global Class A-1
Note may be exchanged, only on or after the Exchange Date, for a beneficial
interest held by the related transferor in the form of a Permanent Regulation S
Global Class A-1 Note, upon delivery to the Note Registrar of a certification
substantially in the form of Exhibit D-5 hereto (a "Clearing System
Certificate").

such CARAT 2007-SN1 Noteholder for all purposes of this CARAT Indenture.

the Issuer in respect of the CARAT 2007-SN1 Notes and this CARAT Indenture may
be served. The Issuer hereby initially appoints the CARAT Indenture Trustee to
serve as its agent for the foregoing purposes. The Issuer shall give prompt
written notice to the CARAT Indenture Trustee of the location, and of any change
in the location, of the Agency Office. If at any time the Issuer shall fail to
maintain any such office or agency or shall fail to furnish the CARAT Indenture
Trustee with the address thereof, such surrenders, notices and demands may be
made or served at the Corporate Trust Office of the CARAT Indenture Trustee, and
the Issuer hereby appoints the CARAT Indenture Trustee as its agent to receive
all such surrenders, notices and demands.

     Section 3.3 Money for Payments To Be Held in Trust.

          (a) As provided in Section 8.2(a) and (b), all payments of amounts due

except as provided in this Section 3.3.

          (b) On or before each Distribution Date or the Redemption Date (if

Distribution Account pursuant to Section 4.05 of the Trust Sale and
Administration Agreement an aggregate sum sufficient to pay the amounts then
becoming due with respect to the CARAT 2007-SN1 Notes, such sum to be held in
trust for the benefit of the Persons entitled thereto.

          (c) The Issuer shall cause each Paying Agent other than the CARAT
Indenture Trustee to execute and deliver to the CARAT Indenture Trustee an
instrument in which such Paying Agent shall agree with the CARAT Indenture
Trustee (and if the CARAT Indenture Trustee acts as Paying Agent, it hereby so
agrees), subject to the provisions of this Section 3.3, that such Paying Agent
shall:


                                       14

<PAGE>

               (i) hold all sums held by it for the payment of amounts due with
respect to the CARAT 2007-SN1 Notes in trust for the benefit of the Persons
entitled thereto until such sums shall be paid to such Persons or otherwise
disposed of as herein provided and pay such sums to such Persons as herein
provided;

               (ii) give the CARAT Indenture Trustee notice of any default by
the Issuer (or any other obligor upon the CARAT 2007-SN1 Notes) of which it has
actual knowledge in the making of any payment required to be made with respect
to the CARAT 2007-SN1 Notes;

               (iii) at any time during the continuance of any such default,
upon the written request of the CARAT Indenture Trustee, forthwith pay to the
CARAT Indenture Trustee all sums so held in trust by such Paying Agent;

               (iv) immediately resign as a Paying Agent and forthwith pay to
the CARAT Indenture Trustee all sums held by it in trust for the payment of
CARAT 2007-SN1 Notes if at any time it ceases to meet the standards required to
be met by a Paying Agent in effect at the time of determination; and

               (v) comply with all requirements of the Code with respect to the
withholding from any payments made by it on any CARAT 2007-SN1 Notes of any
applicable withholding taxes imposed thereon and with respect to any applicable
reporting requirements in connection therewith.

          (d) The Issuer may at any time, for the purpose of obtaining the
satisfaction and discharge of this CARAT Indenture or for any other purpose, by
Issuer Order direct any Paying Agent to pay to the CARAT Indenture Trustee all
sums held in trust by such Paying Agent, such sums to be held by the CARAT
Indenture Trustee upon the same trusts as those upon which the sums were held by
such Paying Agent; and upon such payment by any Paying Agent to the CARAT
Indenture Trustee, such Paying Agent shall be released from all further
liability with respect to such money.

          (e) Subject to applicable laws with respect to escheat of funds, any
money held by the CARAT Indenture Trustee or any Paying Agent in trust for the
payment of any amount due with respect to any CARAT 2007-SN1 Note and remaining
unclaimed for one year after such amount has become due and payable shall be
discharged from such trust and be paid to the Issuer on Issuer Request; and the
Holder of such CARAT 2007-SN1 Note shall thereafter, as an unsecured general
creditor, look only to the Issuer for payment thereof (but only to the extent of
the amounts so paid to the Issuer), and all liability of the CARAT Indenture
Trustee or such Paying Agent with respect to such trust money shall thereupon
cease; provided, however, that the CARAT Indenture Trustee or such Paying Agent,
before being required to make any such payment, may at the expense of the Issuer
cause to be published once, in a newspaper published in the English language,
customarily published on each Business Day and of general circulation in The
City of New York, notice that such money remains unclaimed and that, after a
date specified therein, which shall not be less than 30 days from the date of
such publication, any unclaimed balance of such money then remaining shall be
paid to the Issuer. The CARAT Indenture Trustee may also adopt and employ, at
the expense of the Issuer, any other reasonable


                                       15

<PAGE>

means of notification of such payment (including mailing notice of such payment
to Holders whose CARAT 2007-SN1 Notes have been called but have not been
surrendered for redemption or whose right to or interest in monies due and
payable but not claimed is determinable from the records of the CARAT Indenture
Trustee or of any Paying Agent, at the last address of record for each such
Holder).

     Section 3.4 Existence. The Issuer shall keep in full effect its existence,
rights and franchises as a statutory trust under the laws of the State of
Delaware (unless it becomes, or any successor Issuer hereunder is or becomes,
organized under the laws of any other State or of the United States of America,
in which case the Issuer shall keep in full effect its existence, rights and
franchises under the laws of such other jurisdiction) and shall obtain and
preserve its qualification to do business in each jurisdiction in which such
qualification is or shall be necessary to protect the validity and
enforceability of this CARAT Indenture, the CARAT 2007-SN1 Notes, the Collateral

                                       16

<PAGE>

          (b) The Issuer hereby authorizes the CARAT Indenture Trustee to file
all financing statements, continuation statements or other instruments naming
the Issuer as debtor that are necessary or advisable to perfect, make effective
or continue the Lien of this CARAT Indenture, and authorizes the CARAT Indenture
Trustee to take any such action without its signature.

calendar year.

     Section 3.7 Performance of Obligations; Administration of COLT 2007-SN1
Secured Notes.

          (a) The Issuer shall not take any action and shall use all reasonable
efforts not to permit any action to be taken by others that would release any
Person from any of such Person's material covenants or obligations under any
instrument or agreement included in the CARAT Trust Estate or that would result
in the amendment, hypothecation, subordination, termination or discharge of, or
impair the validity or effectiveness of, any such instrument or agreement,
except as otherwise expressly provided in this CARAT Indenture, the Trust Sale
and Administration Agreement, the Pooling and Administration Agreement or such
other instrument or agreement.

          (b) The Issuer may contract with other Persons to assist it in
performing its duties under this CARAT Indenture, and any performance of such
duties by a Person identified to the CARAT Indenture Trustee in the CARAT Basic
Documents or an Officer's Certificate of the Issuer shall be deemed to be action
taken by the Issuer. Initially, the Issuer has contracted


                                       17

<PAGE>

with the Trust Administrator to assist the Issuer in performing its duties under
this CARAT Indenture.

          (c) The Issuer shall punctually perform and observe all of its
obligations and agreements contained in this CARAT Indenture, the other CARAT

Administration Agreement in accordance with and within the time periods provided
for herein and therein.

          (d) If the Issuer shall have knowledge of the occurrence of a Trust
Administrator Default under the Trust Sale and Administration Agreement, the
Issuer shall promptly notify the CARAT Indenture Trustee and the Rating Agencies
thereof and shall specify in such notice the response or action, if any, the
Issuer has taken or is taking with respect to such default. If a Trust
Administrator Default shall arise from the failure of the Trust Administrator to
perform any of its duties or obligations under this CARAT Indenture, the Trust
Sale and Administration Agreement or the Pooling and Administration Agreement
with respect to the COLT 2007-SN1 Secured Notes, the Issuer and the CARAT
Indenture Trustee shall take all reasonable steps available to them pursuant to
this CARAT Indenture, the Trust Sale and Administration Agreement and the
Pooling and Administration Agreement to remedy such failure.

          (e) Without derogating from the absolute nature of the assignment
granted to the CARAT Indenture Trustee under this CARAT Indenture or the rights
of the CARAT Indenture Trustee hereunder, the Issuer agrees that it shall not,
without the prior written consent of the CARAT Indenture Trustee or the Holders
of at least a majority in Outstanding Amount of the Controlling Class, as
applicable in accordance with the terms of this CARAT Indenture, amend, modify,
waive, supplement, terminate or surrender, or agree to any amendment,
modification, supplement, termination, waiver or surrender of, the terms of any
Collateral or any of the CARAT Basic Documents, or waive timely performance or
observance by the Trust Administrator or the Seller under the Trust Sale and
Administration Agreement or the Pooling and Administration Agreement, or GMAC
under the Pooling and Administration Agreement.

     Section 3.8 Negative Covenants. So long as any CARAT 2007-SN1 Notes are
Outstanding, the Issuer shall not:

          (a) sell, transfer, exchange or otherwise dispose of any of the
properties or assets of the Issuer, except the Issuer may cause the Trust
Administrator to (i) sell or otherwise dispose of Warranty Secured Notes and
Administrative Secured Notes, (ii) make cash payments out of the Designated
Accounts and the Certificate Distribution Account and (iii) take other actions,
in each case as permitted by the CARAT Basic Documents;

          (b) claim any credit on, or make any deduction from the principal or
interest payable in respect of the CARAT 2007-SN1 Notes (other than amounts
properly withheld from such payments under the Code or applicable State law) or
assert any claim against any present or


                                       18

<PAGE>

former CARAT 2007-SN1 Noteholder by reason of the payment of any taxes levied or
assessed upon any part of the CARAT Trust Estate;

          (c) voluntarily commence any insolvency, readjustment of debt,
marshaling of assets and liabilities or other proceeding, or apply for an order
by a court or agency or supervisory authority for the winding-up or liquidation
of its affairs or any other event specified in Section 5.1(f); or

          (d) either (i) permit the validity or effectiveness of this CARAT
Indenture or any other CARAT Basic Document to be impaired, or permit the Lien
of this CARAT Indenture to be amended, hypothecated, subordinated, terminated or
discharged, or permit any Person to be released from any covenants or
obligations with respect to the CARAT 2007-SN1 Notes under this CARAT Indenture
except as may be expressly permitted hereby, (ii) permit any Lien (other than
the Lien of this CARAT Indenture) to be created on or extend to or otherwise
arise upon or burden the CARAT Trust Estate or any part thereof or any interest
therein or the proceeds thereof (other than tax liens and any other Liens that
arise by operation of law, in each case on a Vehicle and arising solely as a
result of an action or omission of the related Lessee), or (iii) permit the Lien
of this CARAT Indenture not to constitute a valid first priority perfected
security interest in the CARAT Trust Estate (other than tax liens and any other
Liens that arise by operation of law, in each case on a Vehicle and arising
solely as a result of an action or omission of the related Lessee).

     Section 3.9 Annual Statement as to Compliance.

     The Issuer shall deliver to the CARAT Indenture Trustee on or before March
15 of each year, beginning March 15, 2008, an Officer's Certificate signed by an
Authorized Officer, dated as of December 31 of the immediately preceding year,
in each case stating that:

          (a) a review of the activities of the Issuer during the preceding
12-month period (or, with respect to the first such Officer's Certificate, such
period as shall have elapsed since the Series 2007-SN1 Closing Date) and of
performance under this CARAT Indenture has been made under such Authorized
Officer's supervision; and

          (b) to the best of such Authorized Officer's knowledge, based on such
review, the Issuer has fulfilled all of its obligations under this CARAT
Indenture throughout such period, or, if there has been a default in the

of any covenant or agreement of the Issuer made in this CARAT Indenture (other
than a covenant or agreement, a default in the observance or performance of

<PAGE>

          (f) the commencement by the Issuer of a voluntary case under any

general assignment for the benefit of creditors, or the failure by the Issuer
generally to pay its debts as such debts become due, or the taking of action by
the Issuer in furtherance of any of the foregoing.

     The Issuer shall deliver to the CARAT Indenture Trustee within five
Business Days after learning of the occurrence thereof, written notice in the
form of an Officer's Certificate of any event which with the giving of notice
and the lapse of time would become a CARAT Event of Default under Section
5.1(d), its status and what action the Issuer is taking or proposes to take with
respect thereto.

     Section 5.2 Acceleration of Maturity; Rescission and Annulment.

          (a) If a CARAT Event of Default should occur and be continuing, then
and in every such case, unless the principal amount of the CARAT 2007-SN1 Notes
shall have already become due and payable, either the CARAT Indenture Trustee or
the Holders of CARAT 2007-SN1 Notes representing not less than a majority of the
Outstanding Amount of the Controlling Class may declare all the CARAT 2007-SN1
Notes to be immediately due and payable, by a notice in writing to the Issuer
(and to the CARAT Indenture Trustee if given by the CARAT 2007-SN1 Noteholders)
setting forth the Event or Events of Default, and upon any such declaration the
unpaid principal amount of such CARAT 2007-SN1 Notes, together with accrued and
unpaid interest thereon through the date of acceleration, shall become
immediately due and payable.

          (b) At any time after such declaration of acceleration of maturity of
the CARAT 2007-SN1 Notes has been made and before a judgment or decree for
payment of the money due thereunder has been obtained by the CARAT Indenture
Trustee as hereinafter provided in this Article V, the Holders of CARAT 2007-SN1
Notes representing a majority of the Outstanding Amount of the Controlling
Class, by written notice to the Issuer and the CARAT Indenture Trustee, may
waive all Defaults set forth in the notice delivered pursuant to Section 5.2(a),
and rescind and annul such declaration and its consequences; provided, however,
that no such rescission and annulment shall extend to or affect any other
Default or impair any right consequent thereto; and provided, further, that if
the CARAT Indenture Trustee shall have proceeded to enforce any right under this
CARAT Indenture and such Proceedings shall have been discontinued or abandoned
because of such rescission and annulment or for any other reason, or such
Proceedings shall have been determined adversely to the CARAT Indenture Trustee,
then and in every such case, the CARAT Indenture Trustee, the Issuer and the
CARAT 2007-SN1 Noteholders, as the case may be, shall be restored respectively
to their former positions and rights hereunder, and all rights, remedies and
powers of the CARAT Indenture Trustee, the Issuer and the CARAT 2007-SN1
Noteholders, as the case may be, shall continue as though no such Proceedings
had been commenced.

     Section 5.3 Collection of Indebtedness and Suits for Enforcement by CARAT
Indenture Trustee.

          (a) The Issuer covenants that if a CARAT Event of Default occurs and
such CARAT Event of Default has not been waived pursuant to Section 5.12, the
Issuer shall, upon demand of the CARAT Indenture Trustee, pay to the CARAT
Indenture Trustee, for the ratable benefit of the CARAT 2007-SN1 Noteholders in
accordance with their respective outstanding principal amounts, the whole amount
then due and payable on such CARAT 2007-SN1 Notes for principal and interest,
with interest upon the overdue principal, at the rate borne by the CARAT
2007-SN1 Notes and in addition thereto such further amount as shall be
sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the CARAT
Indenture Trustee and its agents and counsel.

          (b) If the Issuer shall fail forthwith to pay such amounts upon such
demand, the CARAT Indenture Trustee, in its own name and as trustee of an
express trust, may institute a Proceeding for the collection of the sums so due
and unpaid, may prosecute such Proceeding to judgment or final decree, may
enforce the same against the Issuer or other obligor upon such CARAT 2007-SN1
Notes and may collect in the manner provided by law out of the property of the
Issuer or other obligor upon such CARAT 2007-SN1 Notes, wherever situated, the
monies adjudged or decreed to be payable.

          (c) If a CARAT Event of Default occurs and is continuing, the CARAT
Indenture Trustee may, as more particularly provided in Section 5.4, in its
discretion, proceed to protect and enforce its rights and the rights of the
CARAT 2007-SN1 Noteholders, by such appropriate Proceedings as the CARAT
Indenture Trustee shall deem most effective to protect and enforce any such
rights, whether for the specific enforcement of any covenant or agreement in
this CARAT Indenture or in aid of the exercise of any power granted herein, or
to enforce any other proper remedy or legal or equitable right vested in the
CARAT Indenture Trustee by this CARAT Indenture or by applicable law.

          (d) If there shall be pending, relative to the Issuer or any other
obligor upon the CARAT 2007-SN1 Notes or any Person having or claiming an
ownership interest in the CARAT Trust Estate, Proceedings under Title 11 of the
United States Code or any other applicable federal or State bankruptcy,
insolvency or other similar law, or if a receiver, assignee or trustee in
bankruptcy or reorganization, liquidator, sequestrator or similar official shall
have been appointed for or taken possession of the Issuer or its property or
such other obligor or Person, or in case of any other comparable judicial
Proceedings relative to the Issuer or other obligor upon the CARAT 2007-SN1
Notes, or to the creditors or property of the Issuer or such other obligor, the
CARAT Indenture Trustee, irrespective of whether the principal of any CARAT
2007-SN1 Notes shall then be due and payable as therein expressed or by
declaration or otherwise and irrespective of whether the CARAT Indenture Trustee
shall have made any demand pursuant to the provisions of this Section 5.3, shall
be entitled and empowered, by intervention in such Proceedings or otherwise:

               (i) to file and prove a claim or claims for the whole amount of
principal and interest and all other amounts owing and unpaid in respect of the
CARAT 2007-SN1 Notes and to file such other papers or documents as may be
necessary or advisable in order


                                       28

<PAGE>

to have the claims of the CARAT Indenture Trustee (including any claim for
reasonable compensation to the CARAT Indenture Trustee and each predecessor
CARAT Indenture Trustee, and their respective agents, attorneys and counsel, and
for reimbursement of all expenses and liabilities incurred, and all advances
made, by the CARAT Indenture Trustee and each predecessor CARAT Indenture
Trustee, except as a result of negligence, fraud or bad faith) and of the CARAT
2007-SN1 Noteholders allowed in such Proceedings;

               (ii) unless prohibited by applicable law and regulations, to vote
on behalf of the Holders of CARAT 2007-SN1 Notes in any election of a trustee, a
standby trustee or Person performing similar functions in any such Proceedings;

               (iii) to collect and receive any monies or other property payable
or deliverable on any such claims and to distribute all amounts received with
respect to the claims of the CARAT 2007-SN1 Noteholders and of the CARAT
Indenture Trustee on their behalf; and

               (iv) to file such proofs of claim and other papers or documents
as may be necessary or advisable in order to have the claims of the CARAT
Indenture Trustee or the Holders of CARAT 2007-SN1 Notes allowed in any judicial
proceedings relative to the Issuer, its creditors and its property;

and any trustee, receiver, liquidator, custodian or other similar official in
any such Proceeding is hereby authorized by each of such CARAT 2007-SN1
Noteholders to make payments to the CARAT Indenture Trustee for application in
accordance with the priorities set forth in the CARAT Basic Documents, and, if
the CARAT Indenture Trustee shall consent to the making of payments directly to
such CARAT 2007-SN1 Noteholders, to pay to the CARAT Indenture Trustee such
amounts as shall be sufficient to cover reasonable compensation to the CARAT
Indenture Trustee, each predecessor CARAT Indenture Trustee and their respective
agents, attorneys and counsel, and all other expenses and liabilities incurred,
and all advances made, by the CARAT Indenture Trustee and each predecessor CARAT
Indenture Trustee except as a result of negligence, fraud or bad faith.

          (e) Nothing herein contained shall be deemed to authorize the CARAT
Indenture Trustee to authorize or consent to or vote for or accept or adopt on
behalf of any CARAT 2007-SN1 Noteholder any plan of reorganization, arrangement,
adjustment or composition affecting the CARAT 2007-SN1 Notes or the rights of
any Holder thereof or to authorize the CARAT Indenture Trustee to vote in
respect of the claim of any CARAT 2007-SN1 Noteholder in any such proceeding
except, as aforesaid, to vote for the election of a trustee in bankruptcy or
similar Person.

          (f) All rights of action and of asserting claims under this CARAT
Indenture, or under any of the CARAT 2007-SN1 Notes, may be enforced by the
CARAT Indenture Trustee without the possession of any of the CARAT 2007-SN1
Notes or the production thereof in any trial or other Proceedings relative
thereto, and any such Proceedings instituted by the CARAT Indenture Trustee
shall be brought in its own name as trustee of an express trust, and any
recovery of judgment, subject to the payment of the expenses, disbursements and
compensation of the CARAT Indenture Trustee, each predecessor CARAT Indenture
Trustee


                                       29

<PAGE>

and their respective agents and attorneys, shall be for the benefit of the
Secured Parties in accordance with the priorities set forth in the CARAT Basic
Documents.

          (g) In any Proceedings brought by the CARAT Indenture Trustee (and
also any Proceedings involving the interpretation of any provision of this CARAT
Indenture to which the CARAT Indenture Trustee shall be a party), the CARAT
Indenture Trustee shall be held to represent all the CARAT 2007-SN1 Noteholders,
and it shall not be necessary to make any CARAT 2007-SN1 Noteholder a party to
any such Proceedings.

          (h) With respect to any claims for payments of reimbursement for
expenses, disbursement or compensation of any Person made of the Issuer pursuant
to this Section 5.3, where more than one Person has made such a claim, the
Issuer shall not reimburse any Person other than the CARAT Indenture Trustee for
such amounts if, prior to incurring such expenses, the Affected Parties
reasonably could have avoided such expense by coordinating their claims under
this CARAT Indenture with the CARAT Indenture Trustee.

     Section 5.4 Remedies; Priorities.

          (a) If a CARAT Event of Default shall have occurred and be continuing
and the CARAT 2007-SN1 Notes have been accelerated under Section 5.2(a), the
CARAT Indenture Trustee may do one or more of the following (subject to Section
5.3 and Section 5.5):

               (i) institute Proceedings in its own name and as trustee of an
express trust for the collection of all amounts then due and payable on the
CARAT 2007-SN1 Notes or under this CARAT Indenture with respect thereto, whether
by declaration of acceleration or otherwise, enforce any judgment obtained, and
collect from the Issuer and any other obligor upon such CARAT 2007-SN1 Notes
monies adjudged due;

               (ii) institute Proceedings from time to time for the complete or
partial foreclosure of this CARAT Indenture with respect to the CARAT Trust
Estate;

               (iii) exercise any remedies of a secured party under the UCC and
take any other appropriate action to protect and enforce the rights and remedies
of the CARAT Indenture Trustee and the CARAT 2007-SN1 Noteholders; and

               (iv) sell the CARAT Trust Estate or any portion thereof or rights
or interest therein, at one or more public or private sales called and conducted
in any manner permitted by law or elect to have the Issuer maintain possession
of the CARAT Trust Estate and continue to apply payments on the COLT 2007-SN1
Secured Notes as if there had been no declaration of acceleration; provided,
however, that the CARAT Indenture Trustee may not sell or otherwise liquidate
the CARAT Trust Estate following a CARAT Event of Default and acceleration of
the CARAT 2007-SN1 Notes, unless (i) (A) the Holders of all of the aggregate
Outstanding Amount of the CARAT 2007-SN1 Notes consent thereto or (B) the
proceeds of such sale or liquidation distributable to the CARAT 2007-SN1
Noteholders are sufficient to (x) discharge in full the principal of and the
accrued interest on the CARAT 2007-SN1 Notes, each at the date of such sale or
liquidation and (y) make all distributions from the CARAT Collection Account
described in Sections 8.01(b)(i) through (vi) of the Trust Sale and
Administration Agreement or (C) (x) there has been a CARAT Event of Default
under Section 5.1(a), (b) or (c)


                                       30

<PAGE>

or otherwise arising from a failure to make a required payment of principal on
any CARAT 2007-SN1 Notes, (y) the CARAT Indenture Trustee determines that the
CARAT Trust Estate will not continue to provide sufficient funds for the payment
of principal of and interest on the CARAT 2007-SN1 Notes as and when they would
have become due if the CARAT 2007-SN1 Notes had not been declared due and
payable, and (z) the CARAT Indenture Trustee obtains the consent of the Holders
of a majority of the aggregate Outstanding Amount of the Controlling Class and
(ii) 10 days' prior written notice of sale or liquidation has been given to the
Rating Agencies. In determining such sufficiency or insufficiency with respect
to clauses (B) and (C), the CARAT Indenture Trustee may, but need not, obtain
and rely upon an opinion of an Independent investment banking or accounting firm
of national reputation as to the feasibility of such proposed action and as to
the sufficiency of the CARAT Trust Estate for such purpose:

provided, however, that prior to the exercise of the right to sell all or any
portion of the CARAT Trust Estate as provided herein, the CARAT Indenture
Trustee shall provide a notice in writing to the Issuer (with a copy to the
Seller and the CARAT Owner Trustee) (the "CARAT Event of Default Sale Notice")
of its intention to sell all or any portion of the CARAT Trust Estate (the part
to be sold being the "Subject Estate"), and if the Subject Estate is less than
all of the CARAT Trust Estate, the portion of the CARAT Trust Estate to be sold.
The CARAT Indenture Trustee shall not consummate any sale until at least seven
Business Days after the CARAT Event of Default Sale Notice has been given to the
Issuer (with a copy to the Seller) (the "Authorization Date").

          (b) If the CARAT Indenture Trustee collects any money or property
pursuant to this Article V, it shall pay out the money or property in the
following order:

          FIRST: to the CARAT Indenture Trustee for amounts due under Section
          6.7 and then to the CARAT Owner Trustee for amounts due to the CARAT
          Owner Trustee (not including amounts due for payments to the CARAT
          2007-SN1 Certificateholders) under the Trust Agreement or the Trust
          Sale and Administration Agreement; and

          SECOND: to the CARAT Collection Account, for distribution pursuant to
          Sections 8.01(b) and (e) of the Trust Sale and Administration
          Agreement.

     Section 5.5 Optional Preservation of the CARAT Trust Estate. If the CARAT
2007-SN1 Notes have been declared to be due and payable under Section 5.2
following a CARAT Event of Default and such declaration and its consequences
have not been rescinded and annulled in accordance with Section 5.2(b), the
CARAT Indenture Trustee may, but need not elect to, take and maintain possession
of the CARAT Trust Estate. It is the desire of the parties hereto and the
Secured Parties that there be at all times sufficient funds for the payment of
the Secured Obligations to the Secured Parties and the CARAT Indenture Trustee
shall take such desire into account when determining whether or not to take and
maintain possession of the CARAT Trust Estate. In determining whether to take
and maintain possession of the CARAT Trust Estate, the CARAT Indenture Trustee
may, but need not, obtain and rely upon an opinion of an Independent investment
banking or accounting firm of national reputation as to the


                                       31

<PAGE>

feasibility of such proposed action and as to the sufficiency of the CARAT Trust
Estate for such purpose.

     Section 5.6 Limitation of Suits. No Holder of any CARAT 2007-SN1 Note shall
have any right to institute any Proceeding with respect to this CARAT Indenture,
or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless:

          (a) such Holder has previously given written notice to the CARAT
Indenture Trustee of a continuing CARAT Event of Default;

          (b) the Holders of not less than 25% of the Outstanding Amount of the
Controlling Class have made written request to the CARAT Indenture Trustee to
institute such Proceeding in respect of such CARAT Event of Default in its own
name as CARAT Indenture Trustee hereunder;

          (c) such Holder or Holders have offered to the CARAT Indenture Trustee
reasonable indemnity against the costs, expenses and liabilities to be incurred
in complying with such request;

          (d) the CARAT Indenture Trustee for 60 days after its receipt of such
notice under Section 5.6(a) above, request under Section 5.6(b) above, and offer
of indemnity under Section 5.6(c) above has failed to institute such
Proceedings; and

          (e) no direction inconsistent with such written request has been given
to the CARAT Indenture Trustee during such 60-day period by the Holders of a
majority of the Outstanding Amount of the Controlling Class;

it being understood and intended that no one or more Holders of CARAT 2007-SN1
Notes shall have any right in any manner whatever by virtue of, or by availing
of, any provision of this CARAT Indenture to affect, disturb or prejudice the
rights of any other Holders of CARAT 2007-SN1 Notes or to obtain or to seek to
obtain priority or preference over any other Holders of CARAT 2007-SN1 Notes or
to enforce any right under this CARAT Indenture, except in the manner herein
provided and for the equal, ratable (on the basis of the respective aggregate
amount of principal and interest, respectively, due and unpaid on the CARAT
2007-SN1 Notes held by each CARAT 2007-SN1 Noteholder) and common benefit of all
holders of CARAT 2007-SN1 Notes. For the protection and enforcement of the
provisions of this Section 5.6, each and every CARAT 2007-SN1 Noteholder shall
be entitled to such relief as can be given either at law or in equity.

     If the CARAT Indenture Trustee shall receive conflicting or inconsistent
requests and indemnity from two or more groups of Holders of CARAT 2007-SN1
Notes, each representing less than a majority of the Outstanding Amount of the
Controlling Class, the CARAT Indenture Trustee shall take the action requested
by the group representing the higher percentage of the Outstanding Amount of the
Controlling Class, notwithstanding any other provisions of this CARAT Indenture.

     Section 5.7 Unconditional Rights of CARAT 2007-SN1 Noteholders To Receive
Principal and Interest. Notwithstanding any other provisions in this CARAT
Indenture, the


                                       32

<PAGE>

Holder of any CARAT 2007-SN1 Note shall have the right, which is absolute and
unconditional, to receive payment of the principal of and interest, on such
CARAT 2007-SN1 Note on or after the respective due dates thereof expressed in
such CARAT 2007-SN1 Note or in this CARAT Indenture (or, in the case of
redemption, if applicable, on or after the Redemption Date) and to institute
suit for the enforcement of any such payment, and such right shall not be
impaired without the consent of such Holder.

     Section 5.8 Restoration of Rights and Remedies. If the CARAT Indenture
Trustee or any CARAT 2007-SN1 Noteholder has instituted any Proceeding to
enforce any right or remedy under this CARAT Indenture and such Proceeding has
been discontinued or abandoned for any reason or has been determined adversely
to the CARAT Indenture Trustee or to such CARAT 2007-SN1 Noteholder, then and in
every such case the Issuer, the CARAT Indenture Trustee and the CARAT 2007-SN1
Noteholders shall, subject to any determination in such Proceeding, be restored
severally to their respective former positions hereunder, and thereafter all
rights and remedies of the CARAT Indenture Trustee and the CARAT 2007-SN1
Noteholders shall continue as though no such Proceeding had been instituted.

     Section 5.9 Rights and Remedies Cumulative. No right or remedy herein
conferred upon or reserved to the CARAT Indenture Trustee or to the CARAT
2007-SN1 Noteholders is intended to be exclusive of any other right or remedy,
and every right and remedy shall, to the extent permitted by law, be cumulative
and in addition to every other right and remedy given hereunder or now or
hereafter existing at law or in equity or otherwise. The assertion or employment
of any right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

     Section 5.10 Delay or Omission Not a Waiver. No delay or omission of the
CARAT Indenture Trustee or any Holder of any CARAT 2007-SN1 Note to exercise any
right or remedy accruing upon any Default or CARAT Event of Default shall impair
any such right or remedy or constitute a waiver of any such Default or CARAT
Event of Default or an acquiescence therein. Every right and remedy given by
this Article V or by law to the CARAT Indenture Trustee or to the CARAT 2007-SN1
Noteholders may be exercised from time to time, and as often as may be deemed
expedient, by the CARAT Indenture Trustee or by the CARAT 2007-SN1 Noteholders,
as the case may be.

     Section 5.11 Control by CARAT 2007-SN1 Noteholders. The Holders of a
majority of the Outstanding Amount of the Controlling Class shall, subject to
provision being made for indemnification against costs, expenses and liabilities
in a form satisfactory to the CARAT Indenture Trustee, have the right to direct
the time, method and place of conducting any Proceeding for any remedy available
to the CARAT Indenture Trustee with respect to the CARAT 2007-SN1 Notes or
exercising any trust or power conferred on the CARAT Indenture Trustee;
provided, however, that:

          (a) such direction shall not be in conflict with any rule of law or
with this CARAT Indenture;

          (b) subject to the express terms of Section 5.4, any direction to the
CARAT Indenture Trustee to sell or liquidate the CARAT Trust Estate shall be by
the Holders of CARAT


                                       33

<PAGE>

2007-SN1 Notes representing not less than 100% of the Outstanding Amount of the
CARAT 2007-SN1 Notes;

          (c) if the conditions set forth in Section 5.5 have been satisfied and
the CARAT Indenture Trustee elects to retain the CARAT Trust Estate pursuant to
Section 5.5, then any direction to the CARAT Indenture Trustee by Holders of
CARAT 2007-SN1 Notes representing less than 100% of the Outstanding Amount of
the CARAT 2007-SN1 Notes to sell or liquidate the CARAT Trust Estate shall be of
no force and effect; and

          (d) the Indenture Trustee may take any other action deemed proper by
the Indenture Trustee that is not inconsistent with such direction.

     Section 5.12 Waiver of Past Defaults.

          (a) Prior to the declaration of the acceleration of the maturity of
the CARAT 2007-SN1 Notes as provided in Section 5.2, the Holders of not less
than a majority of the Outstanding Amount of the Controlling Class may waive any
past Default or CARAT Event of Default and its consequences except a Default (i)
in the payment of principal of or interest on any of the CARAT 2007-SN1 Notes or
(ii) in respect of a covenant or provision hereof that cannot be modified or
amended without the consent of the Holder of each CARAT 2007-SN1 Note. In the
case of any such waiver, the Issuer, the CARAT Indenture Trustee and the CARAT
2007-SN1 Noteholders shall be restored to their respective former positions and
rights hereunder; but no such waiver shall extend to any subsequent or other
Default or impair any right consequent thereto.

          (b) Upon any such waiver, such Default shall cease to exist and be
deemed to have been cured and not to have occurred, and any CARAT Event of
Default arising therefrom shall be deemed to have been cured and not to have
occurred, for every purpose of this CARAT Indenture; but no such waiver shall
extend to any subsequent or other Default or CARAT Event of Default or impair
any right consequent thereto.

     Section 5.13 Undertaking for Costs. All parties to this CARAT Indenture
agree, and each Holder of any CARAT 2007-SN1 Note by such Holder's acceptance
thereof shall be deemed to have agreed, that any court may in its discretion
require, in any Proceeding for the enforcement of any right or remedy under this
CARAT Indenture, or in any Proceeding against the CARAT Indenture Trustee for
any action taken, suffered or omitted by it as Indenture Trustee, the filing by
any party litigant in such Proceeding of an undertaking to pay the costs of such
Proceeding, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in such
Proceeding, having due regard to the merits and good faith of the claims or
defenses made by such party litigant; but the provisions of this Section 5.13
shall not apply to:

          (a) any Proceeding instituted by the CARAT Indenture Trustee;

          (b) any Proceeding instituted by any CARAT 2007-SN1 Noteholder, or
group of CARAT 2007-SN1 Noteholders, in each case holding in the aggregate more
than 10% of the Outstanding Amount of the Controlling Class; or


                                       34

<PAGE>

          (c) any Proceeding instituted by any CARAT 2007-SN1 Noteholder for the
enforcement of the payment of principal of or interest on any CARAT 2007-SN1
Note on or after the respective due dates expressed in such CARAT 2007-SN1 Note
and in this CARAT Indenture (or, in the case of redemption, on or after the
Redemption Date).

     Section 5.14 Waiver of Stay or Extension Laws. The Issuer covenants (to the
extent that it may lawfully do so) that it shall not at any time insist upon, or
plead or in any manner whatsoever, claim or take the benefit or advantage of,
any stay or extension law wherever enacted, now or at any time hereafter in
force, that may affect the covenants or the performance of this CARAT Indenture.
The Issuer (to the extent that it may lawfully do so) hereby expressly waives
all benefit or advantage of any such law, and covenants that it shall not
hinder, delay or impede the execution of any power herein granted to the CARAT
Indenture Trustee, but shall suffer and permit the execution of every such power
as though no such law had been enacted.

     Section 5.15 Action on CARAT 2007-SN1 Notes. The CARAT Indenture Trustee's
right to seek and recover judgment on the CARAT 2007-SN1 Notes or under this
CARAT Indenture shall not be affected by the seeking, obtaining or application
of any other relief under or with respect to this CARAT Indenture. Neither the
Lien of this CARAT Indenture nor any rights or remedies of the CARAT Indenture
Trustee or the CARAT 2007-SN1 Noteholders shall be impaired by the recovery of
any judgment by the CARAT Indenture Trustee against the Issuer or by the levy of
any execution under such judgment upon any portion of the CARAT Trust Estate or
upon any of the assets of the Issuer. Any money or property collected by the
CARAT Indenture Trustee shall be applied in accordance with Section 5.4(b).

     Section 5.16 Performance and Enforcement of Certain Obligations.

          (a) Promptly following a request from the CARAT Indenture Trustee to
do so and at the Trust Administrator's expense, the Issuer agrees to take all
such lawful action as the CARAT Indenture Trustee may request to compel or
secure the performance and observance by the Seller and the Trust Administrator
of their respective obligations to the Issuer under or in connection with the
Trust Sale and Administration Agreement and the Pooling and Administration
Agreement or by GMAC of its obligations under or in connection with the Pooling
and Administration Agreement in accordance with the terms thereof or by any
obligor under a Third Party Instrument of its obligations under or in accordance
with a Third Party Instrument, in accordance with the terms thereof, and to
exercise any and all rights, remedies, powers and privileges lawfully available
to the Issuer under or in connection with the Trust Sale and Administration
Agreement, the Pooling and Administration Agreement and any Third Party
Instrument to the extent and in the manner directed by the CARAT Indenture
Trustee, including the transmission of notices of default on the part of the
Seller, the Trust Administrator, or any obligor under a Third Party Instrument
thereunder and the institution of legal or administrative actions or proceedings
to compel or secure performance by the Seller or the Trust Administrator or any
obligor under a Third Party Instrument of their respective obligations under the
Trust Sale and Administration Agreement, the Pooling and Administration
Agreement and any Third Party Instrument.

          (b) If a CARAT Event of Default has occurred and is continuing, the
CARAT Indenture Trustee may, and, at the direction (which direction shall be in
writing or by telephone


                                       35

<PAGE>

(confirmed in writing promptly thereafter)) of the Holders of 66-2/3% of the
Outstanding Amount of the Controlling Class shall, exercise all rights,
remedies, powers, privileges and claims of the Issuer against the Seller, the
Trust Administrator or any obligor under a Third Party Instrument under or in
connection with the Trust Sale and Administration Agreement, the Pooling and
Administration Agreement or a Third Party Instrument, including the right or
power to take any action to compel or secure performance or observance by the
Seller or the Trust Administrator of each of their obligations to the Issuer
thereunder and to give any consent, request, notice, direction, approval,
extension or waiver under the Trust Sale and Administration Agreement, and any
right of the Issuer to take such action shall be suspended.

          (c) If a CARAT Event of Default has occurred and is continuing, the
CARAT Indenture Trustee may, and, at the direction (which direction shall be in
writing or by telephone (confirmed in writing promptly thereafter)) of the
Holders of 66-2/3% of the Outstanding Amount of the CARAT 2007-SN1 Notes shall,
exercise all rights, remedies, powers, privileges and claims of the Seller
against GMAC under or in connection with the Pooling and Administration
Agreement, including the right or power to take any action to compel or secure
performance or observance by GMAC of each of its obligations to the Seller
thereunder and to give any consent, request, notice, direction, approval,
extension or waiver under the Pooling and Administration Agreement, and any
right of the Seller to take such action shall be suspended.

                                   ARTICLE VI
                           THE CARAT INDENTURE TRUSTEE

     Section 6.1 Duties of CARAT Indenture Trustee.

          (a) If a CARAT Event of Default has occurred and is continuing, the
CARAT Indenture Trustee shall exercise the rights and powers vested in it by
this CARAT Indenture and use the same degree of care and skill in its exercise
as a prudent person would exercise or use under the circumstances in the conduct
of such person's own affairs.

          (b) Except during the continuance of a CARAT Event of Default:

               (i) the CARAT Indenture Trustee undertakes to perform such duties
and only such duties as are specifically set forth in this CARAT Indenture and
the Trust Sale and Administration Agreement and no implied covenants or
obligations shall be read into this CARAT Indenture, the Trust Sale and
Administration Agreement or any other CARAT Basic Document against the CARAT
Indenture Trustee;

               (ii) in the absence of bad faith on its part, the CARAT Indenture
Trustee may conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, upon certificates or opinions
furnished to the CARAT Indenture Trustee and conforming to the requirements of
this CARAT Indenture; provided, however, that the CARAT Indenture Trustee shall
examine the certificates and opinions to determine whether or not they conform
to the requirements of this CARAT Indenture.

     15d-18 of the Exchange Act and Item 1122 of Regulation AB under the
     Securities Act;

          (ii) cause a firm of registered public accountants that is qualified

     S-X under the Securities Act and the Exchange Act; and

          (iii) deliver to CARI and any other Person that will be responsible

<PAGE>

     14(d) under the Exchange Act (pursuant to Section 302 of the Sarbanes-Oxley

     provided by the Indenture Trustee pursuant to such clause in signing a
     Sarbanes Certification and filing such with the Commission.

     (c) The reports referred to in Section 6.6(b) shall be delivered on or

intended to constitute expenses of administration under Title 11 of the United
States Code or any other applicable federal or State bankruptcy, insolvency or
similar law.

CARAT Indenture Trustee or its property; or

               (iv) the CARAT Indenture Trustee otherwise becomes incapable of

resign or is removed or if a vacancy exists in the office of the CARAT Indenture
Trustee for any reason (the CARAT Indenture Trustee in such event being referred
to herein as the retiring CARAT Indenture Trustee), the Issuer shall promptly
appoint and designate a successor CARAT Indenture Trustee.

          (c) A successor CARAT Indenture Trustee shall deliver a written
acceptance of its appointment and designation to the retiring CARAT Indenture
Trustee and to the Issuer. Thereupon the resignation or removal of the retiring
CARAT Indenture Trustee shall become effective, and the successor CARAT
Indenture Trustee shall have all the rights, powers and duties of the CARAT
Indenture Trustee under this CARAT Indenture. The successor CARAT Indenture
Trustee shall mail a notice of its succession to CARAT 2007-SN1 Noteholders. The
retiring CARAT Indenture Trustee shall promptly transfer all property held by it
as CARAT Indenture Trustee to the successor CARAT Indenture Trustee.

          (d) If a successor CARAT Indenture Trustee does not take office within
60 days after the CARAT Indenture Trustee gives notice of its intent to resign
or is removed, the retiring Trustee, the Issuer or the Holders of a majority of
the Outstanding Amount of the Controlling Class may petition any court of
competent jurisdiction for the appointment and designation of a successor CARAT
Indenture Trustee.

          (e) If the CARAT Indenture Trustee fails to comply with Section 6.11,
any CARAT 2007-SN1 Noteholder may petition any court of competent jurisdiction
for the removal of the CARAT Indenture Trustee and the appointment of a
successor CARAT Indenture Trustee.

          (f) Notwithstanding the replacement of the CARAT Indenture Trustee
pursuant to this Section 6.8, the Issuer's obligations under Section 6.7 and the
Trust Administrator's corresponding obligations under the Trust Sale and
Administration Agreement and the Pooling and Administration Agreement shall
continue for the benefit of the retiring CARAT Indenture Trustee.

     Section 6.9 Merger or Consolidation of CARAT Indenture Trustee.

          (a) Any corporation into which the CARAT Indenture Trustee may be
merged or with which it may be consolidated, or any corporation resulting from
any merger or consolidation to which the CARAT Indenture Trustee shall be a
party, or any corporation succeeding to the corporate trust business of the
CARAT Indenture Trustee, shall be the successor of the CARAT Indenture Trustee
under this CARAT Indenture; provided, however, that such corporation shall be
eligible under the provisions of Section 6.11, without the execution or filing
of any instrument or any further act on the part of any of the parties to this
CARAT Indenture, anything in this CARAT Indenture to the contrary
notwithstanding.


                                       41

<PAGE>

          (b) If at the time such successor or successors by merger or
consolidation to the CARAT Indenture Trustee shall succeed to the trusts created
by this CARAT Indenture, any of the CARAT 2007-SN1 Notes shall have been
authenticated but not delivered, any such successor to the CARAT Indenture
Trustee may adopt the certificate of authentication of any predecessor trustee,
and deliver such CARAT 2007-SN1 Notes so authenticated, and in case at that time
any of the CARAT 2007-SN1 Notes shall not have been authenticated, any successor
to the CARAT Indenture Trustee may authenticate such CARAT 2007-SN1 Notes either
in the name of any predecessor hereunder or in the name of the successor to the
CARAT Indenture Trustee. In all such cases such certificate of authentication
shall have the same full force as is provided anywhere in the CARAT 2007-SN1
Notes or herein with respect to the certificate of authentication of the CARAT
Indenture Trustee.

     Section 6.10 Appointment of Co-CARAT Indenture Trustee or Separate CARAT
Indenture Trustee.

          (a) Notwithstanding any other provisions of this CARAT Indenture, at
any time, for the purpose of meeting any legal requirement of any jurisdiction
in which any part of the CARAT Trust Estate or any Vehicle may at the time be
located, the CARAT Indenture Trustee shall have the power and may execute and
deliver all instruments to appoint one or more Persons to act as a co-trustee or
co-trustees, or separate trustee or separate trustees, of all or any part of the
CARAT Trust Estate, and to vest in such Person or Persons, in such capacity and
for the benefit of the Secured Parties and (only to the extent expressly
provided herein) the CARAT 2007-SN1 Certificateholders, such title to the CARAT
Trust Estate, or any part hereof, and, subject to the other provisions of this
Section 6.10, such powers, duties, obligations, rights and trusts as the CARAT
Indenture Trustee may consider necessary or desirable. No co-trustee or separate

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 Indenture Trustee shall be conferred or imposed upon and
exercised or performed by the CARAT Indenture 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 Indenture
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
Indenture 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 CARAT Trust Estate 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 Indenture Trustee;

               (ii) no trustee hereunder shall be personally liable by reason of
any act or omission of any other trustee hereunder; and


                                       42

<PAGE>

               (iii) the CARAT Indenture Trustee may at any time accept the
resignation of or remove any separate trustee or co-trustee.

          (c) Any notice, request or other writing given to the CARAT Indenture
Trustee shall be deemed to have been given to each of the then separate trustees
and co-trustees, as effectively as if given to each of them. Every instrument
appointing any separate trustee or co-trustee shall refer to this CARAT
Indenture and the conditions of this Article VI. Each separate trustee and
co-trustee, upon its acceptance of the trusts conferred, shall be vested with
the estates or property specified in its instrument of appointment, either
jointly with the CARAT Indenture Trustee or separately, as may be provided
therein, subject to all the provisions of this CARAT Indenture, specifically
including every provision of this CARAT Indenture relating to the conduct of,
affecting the liability of, or affording protection to, the CARAT Indenture
Trustee. Every such instrument shall be filed with the CARAT Indenture Trustee.

          (d) Any separate trustee or co-trustee may at any time appoint the
CARAT Indenture Trustee as its agent or attorney-in-fact with full power and
authority, to the extent not prohibited by law, to do any lawful act under or in
respect of this CARAT Indenture on its behalf and in its name. If any separate
trustee or co-trustee shall die, become incapable of acting, resign or be
removed, all of its estates, properties, rights, remedies and trusts shall vest
in and be exercised by the CARAT Indenture Trustee, to the extent permitted by
law, without the appointment of a new or successor trustee.

set forth in TIA Section 310(b)(1) are met.

     Section 6.12 Preferential Collection of Claims Against Issuer. The CARAT
Indenture Trustee shall comply with TIA Section 311(a), excluding any creditor

of CARAT 2007-SN1 Notes. All rights of action and claims under this CARAT
Indenture or the CARAT 2007-SN1 Notes may be prosecuted and enforced by the

which such judgment has been obtained.

     Section 6.15 Suit for Enforcement. If a CARAT Event of Default shall occur
and be continuing, the CARAT Indenture Trustee, in its discretion may, subject

Proceeding whether for the specific performance of any covenant or agreement

Certificateholders whose CARAT 2007-SN1 Certificates evidence not less than a
majority of the Voting Interests (as of the close of the preceding Distribution

any amendment, supplement, waiver or other understanding with respect to the
COLT 2007-SN1 Basic Documents or (iii) to take any other action so directed by
such Controlling Class or such Certificateholders, as applicable.

          (c) Notwithstanding Section 6.17(b), in the event that a waiver,
amendment, supplement, or action under a COLT Basic Document requires the
consent or approval of a supermajority (such as 66-2/3 percent) or all of the
Holders of the COLT 2007-SN1 Secured Notes, then the consent of a like
percentage of CARAT 2007-SN1 Noteholders shall be required to take such action
or execute such waiver, amendment or supplement.

2007-SN1 Notes shall have been declared due and payable following a CARAT Event
of Default, but amounts collected or receivable from the CARAT Trust Estate are

practicable, invest and reinvest funds in the Designated Accounts in
"BNY-Hamilton MMF Instit # 746."

          (a) Subject to the payment of its fees and expenses pursuant to

property from the Lien of this CARAT Indenture, or convey the CARAT Indenture
Trustee's interest in the same, in a manner and under circumstances that are
consistent with the provisions of this CARAT Indenture. No party relying upon an

          (b) The CARAT Indenture Trustee shall, at such time as there are no
CARAT 2007-SN1 Notes Outstanding and all sums due to the CARAT Indenture Trustee
pursuant to Section 6.7 have been paid and all amounts owing under each Third

Trust Estate that secured the CARAT 2007-SN1 Notes and the other Secured
Obligations from the Lien of this CARAT Indenture and, where any such portion of
the CARAT Trust Estate is registered in the name of the CARAT Indenture Trustee,
re-convey such property, and release to the Issuer or any other Person entitled
thereto any funds then on deposit in the Designated Accounts. The CARAT
Indenture Trustee shall release property from the Lien of this CARAT Indenture
pursuant to this Section 8.4(b) only upon receipt by it of an Issuer Request and
an Officer's Certificate, an Opinion of Counsel


                                       50

     Section 8.5 Opinion of Counsel. The CARAT Indenture Trustee shall receive
at least seven days' notice when requested by the Issuer to take any action
pursuant to Section 8.4(a), accompanied by copies of any instruments involved,
and the CARAT Indenture Trustee shall also require as a condition to such
action, an Opinion of Counsel, in form and substance satisfactory to the CARAT
Indenture Trustee, stating the legal effect of any such action, outlining the
steps required to complete the same, and concluding that all conditions
precedent to the taking of such action have been complied with and such action
shall not materially and adversely impair the security for the Secured
Obligations or the rights of the Secured Parties in contravention of the
provisions of this CARAT Indenture; provided, however, that such Opinion of
Counsel shall not be required to express an opinion as to the fair value of the
CARAT Trust Estate. Counsel rendering any such opinion may rely, without
independent investigation, on the accuracy and validity of any certificate or
other instrument delivered to the CARAT Indenture Trustee in connection with any
such action.

of the trusts created by this CARAT Indenture, the CARAT Indenture Trustee shall
be entitled to receive, and subject to Sections 6.1 and 6.2, shall be fully
protected in relying upon, an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this CARAT Indenture.
The CARAT Indenture Trustee may, but shall not be obligated to, enter into any
such supplemental indenture that affects the CARAT Indenture Trustee's own
rights, duties, liabilities or immunities under this CARAT Indenture or
otherwise.

     Section 9.4 Effect of Supplemental Indenture.

     Upon the execution of any supplemental indenture pursuant to the provisions
hereof, this CARAT Indenture shall be and be deemed to be modified and amended
in accordance therewith with respect to the CARAT 2007-SN1 Notes affected
thereby, and the respective rights, limitations of rights, obligations, duties,
liabilities and immunities under this CARAT Indenture of the CARAT Indenture
Trustee, the Issuer and the CARAT 2007-SN1 Noteholders shall thereafter be
determined, exercised and enforced hereunder subject in all respects to such
modifications and amendments, and all the terms and conditions of any such
supplemental indenture shall be and be deemed to be part of the terms and
conditions of this CARAT Indenture for any and all purposes.

     Section 9.5 Conformity with Trust Indenture Act. Every amendment of this
CARAT Indenture and every supplemental indenture executed pursuant to this

supplemental indenture pursuant to this Article IX may, and if required by the
CARAT Indenture Trustee shall, bear a notation in form approved by the CARAT
Indenture Trustee as to any matter provided for in such supplemental indenture.
If the Issuer or the CARAT Indenture Trustee shall so determine, new CARAT
2007-SN1 Notes so modified as to conform, in the opinion of the CARAT Indenture
Trustee and the Issuer, to any such supplemental indenture may be prepared and
executed by the Issuer and authenticated and delivered by the CARAT Indenture
Trustee in exchange for Outstanding CARAT 2007-SN1 Notes of the same class.

                            REDEMPTION OF CARAT NOTES

     Section 10.1 Redemption.

     The CARAT 2007-SN1 Notes are subject to redemption in whole, but not in
part, upon the exercise by the Seller of its option to purchase the COLT
2007-SN1 Secured Notes pursuant to Section 8.01 of the Trust Sale and
Administration Agreement. The Distribution Date on which such redemption shall
occur is the Optional Purchase Date identified by Seller in its notice of
exercise of such purchase option (the "Redemption Date"). The purchase price for
the CARAT 2007-SN1 Notes shall be equal to the applicable Redemption Price;
provided, that, the Issuer has available funds sufficient to pay such amount.
The Trust Administrator or the Issuer shall furnish the Rating Agencies notice
of such redemption. If the CARAT 2007-SN1 Notes are to be redeemed pursuant to
this Section 10.1, the Trust Administrator or the Issuer shall furnish notice
thereof to the CARAT Indenture Trustee not later than 25 days prior to the
Redemption Date and the CARAT Indenture Trustee (based on such notice) shall
withdraw from the CARAT Collection Account and deposit into the Note
Distribution Account, on the Redemption Date, the aggregate Redemption Price of
the CARAT 2007-SN1 Notes, whereupon all such CARAT 2007-SN1 Notes shall be due
and payable on the Redemption Date.

     Section 10.2 Form of Redemption Notice.

     Notice of redemption of the CARAT 2007-SN1 Notes under Section 10.1 shall
be given by the CARAT Indenture Trustee by first-class mail, postage prepaid,
mailed not less than five days prior to the applicable Redemption Date to each
CARAT 2007-SN1 Noteholder of record at such CARAT 2007-SN1 Noteholder's address
appearing in the Note Register.

          (a) All notices of redemption shall state:

               (i) the Redemption Date;

               (ii) the applicable Redemption Price; and

               (iii) the place where CARAT 2007-SN1 Notes are to be surrendered
for payment of the Redemption Price (which shall be the Agency Office of the
Issuer to be maintained as provided in Section 3.2).

          (b) Notice of redemption of the CARAT 2007-SN1 Notes shall be given by
the CARAT Indenture Trustee in the name and at the expense of the Issuer.
Failure to give notice of redemption, or any defect therein, to any Holder of
any CARAT 2007-SN1 Note shall not impair or affect the validity of the
redemption of any other CARAT 2007-SN1 Note.

     Section 10.3 CARAT 2007-SN1 Notes Payable on Redemption Date.

     The Notes shall, following notice of redemption as required by Section
10.2, on the Redemption Date cease to be Outstanding for purposes of this CARAT
Indenture and shall thereafter represent only the right to receive the
applicable Redemption Price and (unless the Issuer shall default in the payment
of such Redemption Price) no interest shall accrue on such


                                       55

<PAGE>

Redemption Price for any period after the date to which accrued interest is
calculated for purposes of calculating such Redemption Price.

          (a) Upon any application or request by the Issuer to the CARAT
Indenture Trustee to take any action under any provision of this CARAT
Indenture, the Issuer shall furnish to the CARAT Indenture Trustee: (i) an
Officer's Certificate stating that all conditions precedent, if any, provided

accountants meeting the applicable requirements of this Section 11.1, except
that, in the case of any such application or request as to which the furnishing
of such documents is specifically required by any provision of this CARAT
Indenture, no additional certificate or opinion need be furnished. Every
certificate or opinion with respect to compliance with a condition or covenant
provided for in this CARAT Indenture shall include:

               (i) a statement that each signatory of such certificate or
opinion has read or has caused to be read such covenant or condition and the
definitions herein relating thereto;

               (ii) a brief statement as to the nature and scope of the
examination or investigation upon which the statements or opinions contained in
such certificate or opinion are based;

               (iii) a statement that, in the judgment of each such signatory,
such signatory has made such examination or investigation as is necessary to
enable such signatory to express an informed opinion as to whether or not such
covenant or condition has been complied with; and

               (iv) a statement as to whether, in the opinion of each such
signatory, such condition or covenant has been complied with.

          (b) (i) Prior to the deposit with the CARAT Indenture Trustee of any
Collateral or other property (such as securities) that is to be made the basis
for the release of any property (such as securities) subject to the Lien of this
CARAT Indenture, the Issuer shall, in addition to any obligation imposed in
Section 11.1(a) or elsewhere in this CARAT Indenture, furnish to the CARAT
Indenture Trustee an Officer's Certificate certifying or stating the opinion of
each Person signing such certificate as to the fair value (within 90 days of
such deposit) to the Issuer of the Collateral or other property (such as
securities) to be so deposited.

               (ii) Whenever the Issuer is required to furnish to the CARAT
Indenture Trustee an Officer's Certificate certifying or stating the opinion of
any signer thereof as to the matters described in clause (b)(i) above, the

value to the Issuer of the Collateral and other property (such as securities) to
be so deposited as the basis of any such withdrawal or release since the
commencement of the then current fiscal year of the Issuer, as set forth in the
certificates delivered pursuant to clause (b)(i) above and this clause (b)(ii),
is 10% or more of the Outstanding Amount of the CARAT 2007-SN1 Notes, but such a
certificate need not be furnished with respect to any securities or other
property so deposited, if the fair value thereof to the Issuer as set forth in
the related Officer's Certificate is less than $25,000 or less than one percent
of the Outstanding Amount of the CARAT 2007-SN1 Notes.

               (iii) Other than with respect to the release of any Warranty
Secured Notes or Administrative Secured Notes, whenever any property or
securities are to be released from the Lien of this CARAT Indenture, the Issuer
shall also furnish to the CARAT Indenture Trustee an Officer's Certificate
certifying or stating the opinion of each Person signing such certificate as to
the fair value (within 90 days of such release) of the property or securities
proposed to be released and stating that in the opinion of such Person the
proposed release will not impair the security under this CARAT Indenture in
contravention of the provisions of this CARAT Indenture.

               (iv) Whenever the Issuer is required to furnish to the CARAT
Indenture Trustee an Officer's Certificate certifying or stating the opinion of
any signatory thereof as to the matters described in clause (b)(iii) above, the
Issuer shall also furnish to the CARAT Indenture Trustee an Independent
Certificate as to the same matters if the fair value of the property or
securities and of all other property, other than Warranty Secured Notes and
Administrative Secured Notes, proposed to be released from the Lien of this
CARAT Indenture since the commencement of the then current calendar year, as set
forth in the certificates required by clause (b)(iii) above and this clause
(b)(iv), equals 10% or more of the Outstanding Amount of the CARAT 2007-SN1
Notes, but such a certificate need not be furnished with respect to any release
of securities or other property proposed to be released if the fair value of the
securities or other property proposed to be released as set forth in the related
Officer's Certificate is less than $25,000 or less than one percent of the
Outstanding Amount of the CARAT 2007-SN1 Notes.

               (v) Notwithstanding Section 2.9 or any other provision of this
Section 11.1, the Issuer may (A) collect, liquidate, sell or otherwise dispose
of COLT 2007-SN1 Secured Notes as and to the extent permitted or required by the
CARAT Basic Documents, (B) make cash payments out of the Designated Accounts and
the Certificate Distribution Account as and to the extent permitted or required
by the CARAT Basic Documents and (C) take any other action not inconsistent with
the TIA.

     Section 11.2 Form of Documents Delivered to CARAT Indenture Trustee.

          (a) In any case where several matters are required to be certified by,
or covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.


                                       57

<PAGE>

          (b) Any certificate or opinion of an Authorized Officer of the Issuer
may be based, insofar as it relates to legal matters, upon a certificate or
opinion of, or representations by, counsel, unless such officer knows, or in the
exercise of reasonable care should know, that any certificate, opinion or
representation with respect to the matters upon which his certificate or opinion
is based is erroneous. Any such certificate of an Authorized Officer or Opinion
of Counsel may be based, insofar as it relates to factual matters, upon a
certificate or opinion of, or representations by, an officer or officers of the
Trust Administrator, the Seller or the Issuer, stating that the information with
respect to such factual matters is in the possession of the Trust Administrator,
the Seller or the Issuer, unless such counsel knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to such matters are erroneous.

          (c) Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this CARAT Indenture, they may, but need not, be consolidated
and form one instrument.

          (d) Whenever in this CARAT Indenture, in connection with any
application or certificate or report to the CARAT Indenture Trustee, it is
provided that the Issuer shall deliver any document as a condition of the
granting of such application, or as evidence of the Issuer's compliance with any
term hereof, it is intended that the truth and accuracy, at the time of the
granting of such application or at the effective date of such certificate or
report (as the case may be), of the facts and opinions stated in such document
shall in such case be conditions precedent to the right of the Issuer to have
such application granted or to the sufficiency of such certificate or report.
The foregoing shall not, however, be construed to affect the CARAT Indenture
Trustee's right to rely upon the truth and accuracy of any statement or opinion
contained in any such document as provided in Article VI.

     Section 11.3 Acts of CARAT 2007-SN1 Noteholders.

          (a) Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this CARAT Indenture to be given or taken by
CARAT 2007-SN1 Noteholders or a class of CARAT 2007-SN1 Noteholders may be
embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such CARAT 2007-SN1 Noteholders in person or by agents duly
appointed in writing; and except as herein otherwise expressly provided such
action shall become effective when such instrument or instruments are delivered
to the CARAT Indenture Trustee, and, where it is hereby expressly required, to
the Issuer. Such instrument or instruments (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the "Act" of the CARAT
2007-SN1 Noteholders, as applicable, signing such instrument or instruments.
Proof of execution of any such instrument or of a writing appointing any such
agent shall be sufficient for any purpose of this CARAT Indenture and (subject
to Section 6.1) conclusive in favor of the CARAT Indenture Trustee and the
Issuer, if made in the manner provided in this Section 11.3.

          (b) The fact and date of the execution by any person of any such
instrument or writing may be proved in any manner that the CARAT Indenture
Trustee deems sufficient.


                                       58

<PAGE>

          (c) The ownership of CARAT 2007-SN1 Notes shall be proved by the Note
Register.

          (d) Any request, demand, authorization, direction, notice, consent,
waiver or other action by the Holder of any CARAT 2007-SN1 Notes (or any one or
more Predecessor CARAT 2007-SN1 Notes) shall bind the Holder of every CARAT
2007-SN1 Note issued upon the registration thereof or in exchange therefor or in
lieu thereof, in respect of anything done, omitted or suffered to be done by the
CARAT Indenture Trustee or the Issuer in reliance thereon, whether or not
notation of such action is made upon such CARAT 2007-SN1 Note.

     Section 11.4 Notices, etc., to CARAT Indenture Trustee, Issuer and Rating
Agencies.

     Any request, demand, authorization, direction, notice, consent, waiver or
Act of CARAT 2007-SN1 Noteholders or other documents provided or permitted by
this CARAT Indenture to be made upon, given or furnished to or filed with:

          (a) the CARAT Indenture Trustee by any CARAT 2007-SN1 Noteholder or by
the Issuer shall be made, given, furnished or filed in writing to or with the
CARAT Indenture Trustee at its Corporate Trust Office; or

          (b) the Issuer by the CARAT Indenture Trustee or any CARAT 2007-SN1
Noteholder shall be sufficient for every purpose hereunder if in writing and
either sent by electronic facsimile transmission (with hard copy to follow via
first class mail) or mailed, by certified mail, return receipt requested to the
Issuer and the CARAT Owner Trustee each at the address specified in Appendix B
to the Trust Sale and Administration Agreement.

          The Issuer shall promptly transmit any notice received by it from the
CARAT 2007-SN1 Noteholders to the CARAT Indenture Trustee. The CARAT Indenture
Trustee shall likewise promptly transmit any notice received by it from the
CARAT 2007-SN1 Noteholders to the Issuer.

          (c) Notices required to be given to the Rating Agencies by the Issuer
and the CARAT Indenture Trustee or the CARAT Owner Trustee shall be delivered as
specified in Appendix B to the Trust Sale and Administration Agreement.

     Section 11.5 Notices to CARAT 2007-SN1 Noteholders; Waiver.

          (a) Where this CARAT Indenture provides for notice to the CARAT
2007-SN1 Noteholders of any event, such notice shall be sufficiently given
(unless otherwise herein expressly provided) if it is in writing and mailed,
first-class, postage prepaid to each CARAT 2007-SN1 Noteholder affected by such
event, at such Person's address as it appears on the Note Register, not later
than the latest date, and not earlier than the earliest date, prescribed for the
giving of such notice. If notice to CARAT 2007-SN1 Noteholders is given by mail,
neither the failure to mail such notice nor any defect in any notice so mailed
to any particular CARAT 2007-SN1 Noteholder shall affect the sufficiency of such
notice with respect to other CARAT 2007-SN1 Noteholders, and any notice that is
mailed in the manner herein provided shall conclusively be presumed to have been
duly given regardless of whether such notice is in fact actually received.


                                       59

<PAGE>

          (b) Where this CARAT Indenture provides for notice in any manner, such
notice may be waived in writing by any Person entitled to receive such notice,
either before or after the event, and such waiver shall be the equivalent of
such notice. Waivers of notice by CARAT 2007-SN1 Noteholders shall be filed with
the CARAT Indenture Trustee but such filing shall not be a condition precedent
to the validity of any action taken in reliance upon such a waiver.

          (c) In case, by reason of the suspension of regular mail service as a
result of a strike, work stoppage or similar activity, it shall be impractical
to mail notice of any event of CARAT 2007-SN1 Noteholders when such notice is
required to be given pursuant to any provision of this CARAT Indenture, then any
manner of giving such notice as shall be satisfactory to the CARAT Indenture
Trustee shall be deemed to be a sufficient giving of such notice.

          (d) Where this CARAT Indenture provides for notice to the Rating
Agencies, failure to give such notice shall not affect any other rights or
obligations created hereunder, and shall not under any circumstance constitute a
CARAT Event of Default.

     Section 11.6 Alternate Payment and Notice Provisions.

     Notwithstanding any provision of this CARAT Indenture or any of the CARAT
2007-SN1 Notes to the contrary, the Issuer may enter into any agreement with any
Holder of a CARAT 2007-SN1 Note providing for a method of payment, or notice by
the CARAT Indenture Trustee or any Paying Agent to such Holder, that is
different from the methods provided for in this CARAT Indenture for such
payments or notices. The Issuer shall furnish to the CARAT Indenture Trustee a
copy of each such agreement and the CARAT Indenture Trustee shall cause payments
to be made and notices to be given in accordance with such agreements and at the
expense of the Issuer.

     Section 11.7 Conflict with Trust Indenture Act.

          (a) If any provision hereof limits, qualifies or conflicts with
another provision hereof that is required to be included in this CARAT Indenture
by any of the provisions of the TIA, such required provision shall control.

          (b) The provisions of TIA Sections 310 through 317 that impose duties
on any Person (including the provisions automatically deemed included herein
unless expressly excluded by this CARAT Indenture) are a part of and govern this
CARAT Indenture, whether or not physically contained herein.

     Section 11.8 Effect of Headings and Table of Contents. The Article and
Section headings herein and the Table of Contents are for convenience only and
shall not affect the construction hereof.

     Section 11.9 Successors and Assigns.

          (a) All covenants and agreements in this CARAT Indenture and the CARAT
2007-SN1 Notes by the Issuer shall bind its successors and assigns, whether so
expressed or not.

or not.

     Section 11.10 Severability.

     In case any provision in this CARAT Indenture or in the CARAT 2007-SN1
Notes shall be invalid, illegal or unenforceable, the validity, legality, and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

     Section 11.11 Benefits of CARAT Indenture.

     Nothing in this CARAT Indenture or in the CARAT 2007-SN1 Notes, express or
implied, shall give to any Person, other than the parties hereto and their
successors hereunder, and to the extent expressly provided herein, the CARAT
2007-SN1 Noteholders, the CARAT 2007-SN1 Certificateholders, any other party
secured hereunder, any other Person with an ownership interest in any part of

     If the date on which any payment is due shall not be a Business Day, then
(notwithstanding any other provision of the CARAT 2007-SN1 Notes or this CARAT
Indenture) payment need not be made on such date, but may be made on the next
succeeding Business Day with the same force and effect as if made on the date on
which nominally due, and no interest shall accrue for the period from and after
any such nominal date.

     Section 11.13 GOVERNING LAW.

     THIS CARAT INDENTURE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE INTERNAL LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO THE PRINCIPLES OF
CONFLICTS OF LAWS THEREOF OR OF ANY OTHER JURISDICTION (OTHER THAN SECTIONS

     Section 11.14 Counterparts.

which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

     If this CARAT Indenture is subject to recording in any appropriate public
recording offices, such recording is to be effected by the Issuer and at its
expense accompanied by an Opinion of Counsel (which may be counsel to the CARAT
Indenture Trustee or any other counsel reasonably acceptable to the CARAT
Indenture Trustee) to the effect that such recording is necessary either for the

Indenture Trustee under this CARAT Indenture.

     Section 11.16 No Recourse.

     No recourse may be taken, directly or indirectly, with respect to the
obligations of the Issuer, the CARAT Owner Trustee or the CARAT Indenture
Trustee on the CARAT 2007-SN1 Notes or under this CARAT Indenture or any

against:

          (a) the CARAT Indenture Trustee or the CARAT Owner Trustee in its

individual capacity) and except that any such partner, owner or beneficiary
shall be fully liable, to the extent provided by applicable law, for any unpaid

appointing a receiver, liquidator, assignee, trustee, custodian, sequestrator or

                                       62

<PAGE>

the Seller in respect to such obligations, that such obligations shall not
constitute a claim against the Seller in respect to such obligations, and that
such obligations shall not constitute a claim against the Issuer in the event
that the Issuer's assets are insufficient to pay in full such obligations, in
each case for one year and one day after all CARAT 2007-SN1 Notes are paid in
full.

     Section 11.18 Inspection.

     The Issuer agrees that, on reasonable prior notice, it shall permit any

CARAT Indenture and all indentures supplemental thereto reference is hereby made
for a statement of the respective rights and obligations thereunder of the
Issuer, the CARAT Indenture Trustee and the CARAT 2007-SN1 Noteholders. The
[Class A-2a] [Class A-3a] [Class B] [Class C] [Class D] Notes are one of several
duly authorized classes of CARAT 2007-SN1 Notes of the Issuer issued pursuant to
the CARAT Indenture (collectively, as to all CARAT 2007-SN1 Notes of all such
classes, the "CARAT 2007-SN1 Notes"). The CARAT 2007-SN1 Notes are governed by
and subject to all terms of the CARAT Indenture (which terms are incorporated
herein and made a part hereof), to which CARAT Indenture the Holder of this
CARAT 2007-SN1 Note by virtue of acceptance hereof assents and by which such
Holder is bound. All capitalized terms used and not otherwise defined in this
CARAT 2007-SN1 Note that are defined in the CARAT Indenture, as supplemented or
amended, shall have the meanings assigned to them in or pursuant to the CARAT
Indenture.

The [Class A-2a] [Class A-3a] [Class B] [Class C] [Class D] Notes and all other
CARAT 2007-SN1 Notes issued pursuant to the CARAT Indenture are and will be
equally and ratably secured by the Collateral pledged as security therefor as
provided in the CARAT Indenture.

By acquiring a CARAT 2007-SN1 Note or any interest therein, each purchaser and
transferee will be deemed to represent and warrant that either (A) it is not (i)
an "employee benefit plan" (as defined in Section 3(3) of the United States
Employee Retirement Income Security Act of 1974, as amended ("ERISA"), that is
subject to the provisions of Title I of ERISA, (ii) a "plan" as described in
Section 4975(e)(1) of the Internal Revenue Code of 1986, as amended (the
"Code"), (iii) an entity whose underlying assets include plan assets by reason
of an employee benefit plan's or a plan's investment in the entity or (iv) other
plan subject to applicable law that is substantially similar to Section 406 of
ERISA or Section 4975 of the Code or (B) the acquisition, holding and
disposition of the CARAT 2007-SN1 Note will not give rise to a non-exempt
prohibited transaction under Section 406(a) of ERISA, Section 4975 of the Code
or a violation of any substantially similar applicable law.

Each CARAT 2007-SN1 Noteholder or Note Owner, by acceptance of a CARAT 2007-SN1
Note or, in the case of a Note Owner, a beneficial interest in a CARAT 2007-SN1
Note, covenants and agrees that no recourse may be taken, directly or
indirectly, with respect to the obligations of the Issuer, the CARAT Owner
Trustee or the CARAT Indenture Trustee on the CARAT 2007-SN1 Notes or under the
CARAT Indenture or any certificate or other writing delivered in connection
therewith, against (i) the CARAT Indenture Trustee or the CARAT Owner Trustee in
their individual capacities, (ii) the Seller or any other owner of a beneficial
interest in the Issuer or (iii) any partner, owner, beneficiary, agent, officer,
director or employee of the CARAT Indenture Trustee or the CARAT Owner Trustee
in their individual capacities,


                                     C-1-8

<PAGE>

any holder of a beneficial interest in the Issuer, the CARAT Owner Trustee or
the CARAT Indenture Trustee or of any successor or assign of the CARAT Indenture
Trustee or the CARAT Owner Trustee in their individual capacities, except as any
such Person may have expressly agreed and except that any such partner, owner or
beneficiary shall be fully liable, to the extent provided by applicable law, for
any unpaid consideration for stock, unpaid capital contribution or failure to
pay any instalment or call owing to such entity.

Each CARAT 2007-SN1 Noteholder or Note Owner, by acceptance of a CARAT 2007-SN1
Note or, in the case of a Note Owner, a beneficial interest in a CARAT 2007-SN1
Note, covenants and agrees that by accepting the benefits of the CARAT Indenture
such CARAT 2007-SN1 Noteholder will not, prior to the date which is one year and
one day after the termination of the CARAT Indenture, acquiesce, petition or
otherwise invoke or cause the Seller or the Issuer to invoke the process of any
court or government authority for the purpose of commencing or sustaining a case
against the Seller or the Issuer under any federal or state bankruptcy,
insolvency or similar law or appointing a receiver, liquidator, assignee,
trustee, custodian, sequestrator or other similar official of the Seller or the
Issuer or any substantial part of its property, or ordering the winding up or
liquidation of the affairs of the Seller or the Issuer.

Each CARAT 2007-SN1 Noteholder or Note Owner, by acceptance of a CARAT 2007-SN1
Note or, in the case of a Note Owner, a beneficial interest in a CARAT 2007-SN1
Note, expresses its intention that this CARAT 2007-SN1 Note qualifies under
applicable tax law as indebtedness secured by the Collateral and, unless
otherwise required by appropriate taxing authorities, agrees to treat the CARAT
2007-SN1 Notes as indebtedness secured by the Collateral for the purpose of
federal income taxes, state and local income and franchise taxes, Michigan
single business tax, and any other taxes imposed upon, measured by or based upon
gross or net income.

Prior to the due presentment for registration of transfer of this CARAT 2007-SN1
Note, the Issuer, the CARAT Indenture Trustee and any agent of the Issuer or the
CARAT Indenture Trustee may treat the Person in whose name this CARAT 2007-SN1
Note (as of the day of determination or as of such other date as may be
specified in the CARAT Indenture) is registered as the owner hereof for all
purposes, whether or not this CARAT 2007-SN1 Note shall be overdue, and neither
the Issuer, the CARAT Indenture Trustee nor any such agent shall be affected by
notice to the contrary.

The CARAT Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the CARAT 2007-SN1 Noteholders under the CARAT
Indenture at any time by the Issuer with the consent of the Holders of CARAT
2007-SN1 Notes representing a majority of the Outstanding Amount of the
Controlling Class. The CARAT Indenture also contains provisions permitting the
Holders of CARAT 2007-SN1 Notes representing specified percentages of the
Outstanding Amount of the Controlling Class, on behalf of the Holders of all
CARAT 2007-SN1 Notes, to waive compliance by the Issuer with certain provisions
of the CARAT Indenture and certain past defaults under the CARAT Indenture and
their consequences. Any such consent or waiver by the Holder of this CARAT
2007-SN1 Note (or any one of more Predecessor Notes) shall be conclusive and
binding upon such Holder and upon all future Holders of this CARAT 2007-SN1 Note
and of any CARAT 2007-SN1 Note issued upon the registration of transfer hereof
or in


                                     C-1-9

<PAGE>

exchange hereof or in lieu hereof whether or not notation of such consent or
waiver is made upon this CARAT 2007-SN1 Note. The CARAT Indenture also permits
the CARAT Indenture Trustee to amend or waive certain terms and conditions set
forth in the CARAT Indenture without the consent of the CARAT 2007-SN1
Noteholders.

The term "Issuer" as used in this CARAT 2007-SN1 Note includes any successor to
the Issuer under the CARAT Indenture.

The Issuer is permitted by the CARAT Indenture, under certain circumstances, to
merge or consolidate, subject to the rights of the CARAT Indenture Trustee and
the Holders of CARAT 2007-SN1 Notes under the CARAT Indenture.

The CARAT 2007-SN1 Notes are issuable only in registered form in denominations
as provided in the CARAT Indenture, subject to certain limitations therein set
forth.

THIS CARAT 2007-SN1 NOTE AND THE CARAT INDENTURE SHALL BE CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO
THE PRINCIPLES OF CONFLICTS OF LAWS THEREOF OR OF ANY OTHER JURISDICTION (OTHER
THAN SECTIONS 5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW), AND
THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER AND THEREUNDER
SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

No reference herein to the CARAT Indenture and no provision of this CARAT
2007-SN1 Note or of the CARAT Indenture shall alter or impair the obligation of
the Issuer, which is absolute and unconditional, to pay the principal of and
interest on this CARAT 2007-SN1 Note at the times, place and rate, and in the
coin or currency herein prescribed.

Anything herein to the contrary notwithstanding, except as expressly provided in
the CARAT Basic Documents, neither the Seller, the Trust Administrator, the
CARAT Indenture Trustee nor the CARAT Owner Trustee in their respective
individual capacities, any owner of a beneficial interest in the Issuer, nor any
of their respective partners, beneficiaries, agents, officers, directors,
employees or successors or assigns, shall be personally liable for, nor shall
recourse be had to any of them for, the payment of principal of or interest on,
or performance of, or omission to perform, any of the covenants, obligations or
indemnifications contained in this CARAT 2007-SN1 Note or the CARAT Indenture,
it being expressly understood that said covenants, obligations and
indemnifications have been made by the CARAT Owner Trustee solely as the CARAT
Owner Trustee in the assets of the Issuer. The Holder of this CARAT 2007-SN1
Note by the acceptance hereof agrees that, except as expressly provided in the
CARAT Basic Documents, in the case of a CARAT Event of Default under the CARAT
Indenture, the Holder shall have no claim against any of the foregoing for any
deficiency, loss or claim therefrom; provided, however, that nothing contained
herein shall be taken to prevent recourse to, and enforcement against, the
assets of the Issuer for any and all liabilities, obligations and undertakings
contained in the CARAT Indenture or in this CARAT 2007-SN1

     THIS CARAT 2007-SN1 NOTE AND THE CARAT INDENTURE SHALL BE CONSTRUED IN

THAN SECTIONS 5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW), AND
THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER AND THEREUNDER
SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

No reference herein to the CARAT Indenture and no provision of this CARAT
2007-SN1 Note or of the CARAT Indenture shall alter or impair the obligation of
the Issuer, which is absolute and unconditional, to pay the principal of and
interest on this CARAT 2007-SN1 Note at the times, place and rate, and in the
coin or currency herein prescribed.

Anything herein to the contrary notwithstanding, except as expressly provided in

CARAT Indenture Trustee nor the CARAT Owner Trustee in their respective
individual capacities, any owner of a beneficial interest in the Issuer, nor any
of their respective partners, beneficiaries, agents, officers, directors,
employees or successors or assigns, shall be personally liable for, nor shall
recourse be had to any of them for, the payment of principal of or interest on,
or performance of, or omission to perform, any of the covenants, obligations or
indemnifications contained in this CARAT 2007-SN1 Note or the CARAT Indenture,
it being expressly understood that said covenants, obligations and

Note by the acceptance hereof agrees that, except as expressly provided in the
CARAT Basic Documents, in the case of a CARAT Event of Default under the CARAT
Indenture, the Holder shall have no claim against any of the foregoing for any
deficiency, loss or claim therefrom; provided, however, that nothing contained

assets of the Issuer for any and all liabilities, obligations and undertakings
contained in the CARAT Indenture or in this CARAT 2007-SN1 Note.

Issuer and The Bank of New York Trust Company, N.A., as trustee (the "CARAT
Indenture Trustee", which term includes any successor trustee under the CARAT

CARAT 2007-SN1 Note by virtue of acceptance hereof assents and by which such
Holder is bound. All capitalized terms used and not otherwise defined in this
CARAT 2007-SN1 Note that are defined in the CARAT Indenture, as supplemented or
amended, shall have the meanings assigned to them in or pursuant to the CARAT
Indenture.

     The [Class A-1a][Class A-1b] Notes and all other CARAT 2007-SN1 Notes

Section 4975(e)(1) of the Internal Revenue Code of 1986, as amended (the
"Code"), (iii) an entity whose underlying assets include plan assets by reason
of an employee benefit plan's or a plan's investment in the entity or (iv) other
plan subject to applicable law that is substantially similar to Section 406 of
ERISA or Section 4975 of the Code or (B) the acquisition, holding and
disposition of the CARAT 2007-SN1 Note will not give rise to a non-exempt
prohibited transaction under Section 406(a) of ERISA, Section 4975 of the Code
or a violation of any substantially similar applicable law).

     Each CARAT 2007-SN1 Noteholder or Note Owner, by acceptance of a CARAT
2007-SN1 Note or, in the case of a Note Owner, a beneficial interest in a CARAT
2007-SN1 Note, covenants and agrees that no recourse may be taken, directly or

Trustee or the CARAT Indenture Trustee on the CARAT 2007-SN1 Notes or under the
CARAT Indenture or any certificate or other writing delivered in connection
therewith, against (i) the CARAT Indenture Trustee or the CARAT Owner Trustee in

interest in the Issuer or (iii) any partner, owner, beneficiary, agent, officer,
director or employee of the CARAT Indenture Trustee or the CARAT Owner Trustee
in their individual capacities, any holder of a beneficial interest in the

Indenture Trustee or of any successor or assign of the CARAT Indenture Trustee
or the CARAT Owner Trustee in their individual capacities, except as any such
Person may have expressly agreed and except that any such partner, owner or
beneficiary shall be fully liable, to the extent provided by applicable law, for
any unpaid consideration for stock, unpaid capital contribution or failure to
pay any instalment or call owing to such entity.

     Each CARAT 2007-SN1 Noteholder or Note Owner, by acceptance of a CARAT
2007-SN1 Note or, in the case of a Note Owner, a beneficial interest in a CARAT
2007-SN1 Note, covenants and agrees that by accepting the benefits of the CARAT
Indenture such CARAT 2007-SN1 Noteholder will not, prior to the date which is
one year and one day after the termination of the CARAT Indenture, acquiesce,
petition or otherwise invoke or cause the Seller or the Issuer to invoke the
process of any court or government authority for the purpose of commencing or
sustaining a case against the Seller or the Issuer under any federal or state
bankruptcy, insolvency or similar law or appointing a receiver, liquidator,
assignee, trustee, custodian, sequestrator or other similar official of the
Seller or the Issuer or any substantial part of its property, or ordering the
winding up or liquidation of the affairs of the Seller or the Issuer.

     Each CARAT 2007-SN1 Noteholder or Note Owner, by acceptance of a CARAT
2007-SN1 Note or, in the case of a Note Owner, a beneficial interest in a CARAT
2007-SN1 Note, expresses its intention that this CARAT 2007-SN1 Note qualifies
under applicable tax law as indebtedness secured by the Collateral and, unless
otherwise required by appropriate taxing authorities, agrees to treat the CARAT
2007-SN1 Notes as indebtedness secured by the Collateral for the purpose of
federal income taxes, state and local income and franchise taxes, Michigan
single business tax, and any other taxes imposed upon, measured by or based upon
gross or net income.

     Prior to the due presentment for registration of transfer of this CARAT
2007-SN1 Note, the Issuer, the CARAT Indenture Trustee and any agent of the
Issuer or the CARAT Indenture Trustee may treat the Person in whose name this
CARAT 2007-SN1 Note (as of the day of determination or as of such other date as
may be specified in the CARAT Indenture) is registered as the owner hereof for
all purposes, whether or not this CARAT 2007-SN1 Note shall be overdue, and
neither the Issuer, the CARAT Indenture Trustee nor any such agent shall be
affected by notice to the contrary.

     The CARAT Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the CARAT 2007-SN1 Noteholders under the CARAT
Indenture at any time by the Issuer with the consent of the Holders of CARAT
2007-SN1 Notes representing a majority of the Outstanding Amount of the
Controlling Class. The CARAT Indenture also contains provisions permitting the
Holders of CARAT 2007-SN1 Notes representing specified percentages of the
Outstanding Amount of the Controlling Class, on behalf of the Holders of all the
CARAT 2007-SN1 Notes, to waive compliance by the Issuer with certain provisions
of the CARAT Indenture and certain past defaults under the CARAT Indenture and
their consequences. Any such consent or waiver by the Holder of this CARAT
2007-SN1 Note (or any one of more Predecessor Notes) shall be conclusive and
binding upon such Holder and upon all future Holders of this CARAT 2007-SN1 Note
and of any CARAT 2007-SN1 Note issued upon the registration of transfer hereof
or in exchange hereof or in lieu hereof whether or not notation of such consent
or waiver

successor to the Issuer under the CARAT Indenture.

     The Issuer is permitted by the CARAT Indenture, under certain
circumstances, to merge or consolidate, subject to the rights of the CARAT
Indenture Trustee and the Holders of CARAT 2007-SN1 Notes under the CARAT
Indenture.

     The CARAT 2007-SN1 Notes are issuable only in registered form in

therein set forth.

     THIS CARAT 2007-SN1 NOTE AND THE CARAT INDENTURE SHALL BE CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO
THE PRINCIPLES OF CONFLICTS OF LAWS THEREOF OR OF ANY OTHER JURISDICTION (OTHER
THAN SECTIONS 5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW), AND
THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER AND THEREUNDER
SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

     No reference herein to the CARAT Indenture and no provision of this CARAT
2007-SN1 Note or of the CARAT Indenture shall alter or impair the obligation of
the Issuer, which is absolute and unconditional, to pay the principal of and
interest on this CARAT 2007-SN1 Note at the times, place and rate, and in the
coin or currency herein prescribed.

     Anything herein to the contrary notwithstanding, except as expressly
provided in the CARAT Basic Documents, neither the Seller, the Trust
Administrator, the CARAT Indenture Trustee nor the CARAT Owner Trustee in their
respective individual capacities, any owner of a beneficial interest in the
Issuer, nor any of their respective partners, beneficiaries, agents, officers,
directors, employees or successors or assigns, shall be personally liable for,
nor shall recourse be had to any of them for, the payment of principal of or
interest on, or performance of, or omission to perform, any of the covenants,
obligations or indemnifications contained in this CARAT 2007-SN1 Note or the
CARAT Indenture, it being expressly understood that said covenants, obligations
and indemnifications have been made by the CARAT Owner Trustee solely as the
CARAT Owner Trustee in the assets of the Issuer. The Holder of this CARAT
2007-SN1 Note by the acceptance hereof agrees that, except as expressly provided
in the CARAT Basic Documents, in the case of a CARAT Event of Default under the
CARAT Indenture, the Holder shall have no claim against any of the foregoing for
any deficiency, loss or claim therefrom; provided, however, that nothing
contained herein shall be taken to prevent recourse to, and enforcement against,
the assets of the Issuer for any and all liabilities, obligations and
undertakings contained in the CARAT Indenture or in this CARAT 2007-SN1 Note.

     This CARAT 2007-SN1 Note is one of a duly authorized issue of CARAT
2007-SN1 Notes of the Issuer, designated as its [Class A-1a][Class A-1b] Asset
Backed Notes (herein called the "[Class A-1a][Class A-1b] Notes"), all issued
under a CARAT Indenture, dated as of June 7, 2007 (such CARAT Indenture, as
supplemented or amended, is herein called the "CARAT Indenture"), between the
Issuer and The Bank of New York Trust Company, N.A., as trustee (the "CARAT
Indenture Trustee", which term includes any successor trustee under the CARAT
Indenture), to which CARAT Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights and
obligations thereunder of the Issuer, the CARAT Indenture Trustee and the CARAT
2007-SN1 Noteholders. The [Class A-1a][Class A-1b] Notes are one of several duly

CARAT Indenture (collectively, as to all CARAT 2007-SN1 Notes of all such
classes, the "CARAT 2007-SN1 Notes"). The CARAT 2007-SN1 Notes are governed by
and subject to all terms of the CARAT Indenture (which terms are incorporated
herein and made a part hereof), to which CARAT Indenture the Holder of this
CARAT 2007-SN1 Note by virtue of acceptance hereof assents and by which such
Holder is bound. All capitalized terms used and not otherwise defined in this
CARAT 2007-SN1 Note that are defined in the CARAT Indenture, as supplemented or
amended, shall have the meanings assigned to them in or pursuant to the CARAT
Indenture.

     The [Class A-1a][Class A-1b] Notes and all other CARAT 2007-SN1 Notes
issued pursuant to the CARAT Indenture are and will be equally and ratably
secured by the Collateral pledged as security therefor as provided in the CARAT
Indenture.

     By acquiring a CARAT 2007-SN1 Note or any interest therein, each purchaser
and transferee will be deemed to represent and warrant that either (A) it is not

subject to the provisions of Title I of ERISA, (ii) a "plan" as described in
Section 4975(e)(1) of the Internal Revenue Code of 1986, as amended (the
"Code"), (iii) an entity whose underlying assets include plan assets by reason
of an employee benefit plan's or a plan's investment in the entity or (iv) other
plan subject to applicable law that is substantially similar to Section 406 of
ERISA or Section 4975 or (B) the acquisition, holding and disposition of the
CARAT 2007-SN1 Note will not give rise to a non-exempt prohibited transaction
under Section 406(a) of ERISA, Section 4975 of the Code or a violation of any
substantially similar applicable law.

     Each CARAT 2007-SN1 Noteholder or Note Owner, by acceptance of a CARAT
2007-SN1 Note or, in the case of a Note Owner, a beneficial interest in a CARAT
2007-SN1 Note, covenants and agrees that no recourse may be taken, directly or
indirectly, with respect to the obligations of the Issuer, the CARAT Owner
Trustee or the CARAT Indenture Trustee on the CARAT 2007-SN1 Notes or under the
CARAT Indenture or any certificate or other writing delivered in connection
therewith, against (i) the CARAT Indenture Trustee or the CARAT Owner Trustee in
their individual capacities, (ii) the Seller or any other owner of a beneficial
interest in the Issuer or (iii) any partner, owner, beneficiary, agent, officer,
director or employee of the CARAT Indenture Trustee or the CARAT Owner Trustee
in their individual capacities, any holder of a beneficial interest in the
Issuer, the CARAT Owner Trustee or the CARAT

<PAGE>

Indenture Trustee or of any successor or assign of the CARAT Indenture Trustee
or the CARAT Owner Trustee in their individual capacities, except as any such
Person may have expressly agreed and except that any such partner, owner or
beneficiary shall be fully liable, to the extent provided by applicable law, for
any unpaid consideration for stock, unpaid capital contribution or failure to
pay any instalment or call owing to such entity.

     Each CARAT 2007-SN1 Noteholder or Note Owner, by acceptance of a CARAT
2007-SN1 Note or, in the case of a Note Owner, a beneficial interest in a CARAT
2007-SN1 Note, covenants and agrees that by accepting the benefits of the CARAT
Indenture such CARAT 2007-SN1 Noteholder will not, prior to the date which is
one year and one day after the termination of the CARAT Indenture, acquiesce,
petition or otherwise invoke or cause the Seller or the Issuer to invoke the
process of any court or government authority for the purpose of commencing or
sustaining a case against the Seller or the Issuer under any federal or state
bankruptcy, insolvency or similar law or appointing a receiver, liquidator,
assignee, trustee, custodian, sequestrator or other similar official of the
Seller or the Issuer or any substantial part of its property, or ordering the
winding up or liquidation of the affairs of the Seller or the Issuer.

     Each CARAT 2007-SN1 Noteholder or Note Owner, by acceptance of a CARAT
2007-SN1 Note or, in the case of a Note Owner, a beneficial interest in a CARAT
2007-SN1 Note, expresses its intention that this CARAT 2007-SN1 Note qualifies
under applicable tax law as indebtedness secured by the Collateral and, unless
otherwise required by appropriate taxing authorities, agrees to treat the CARAT
2007-SN1 Notes as indebtedness secured by the Collateral for the purpose of
federal income taxes, state and local income and franchise taxes, Michigan
single business tax, and any other taxes imposed upon, measured by or based upon
gross or net income.

     Prior to the due presentment for registration of transfer of this CARAT
2007-SN1 Note, the Issuer, the CARAT Indenture Trustee and any agent of the
Issuer or the CARAT Indenture Trustee may treat the Person in whose name this
CARAT 2007-SN1 Note (as of the day of determination or as of such other date as
may be specified in the CARAT Indenture) is registered as the owner hereof for
all purposes, whether or not this CARAT 2007-SN1 Note shall be overdue, and
neither the Issuer, the CARAT Indenture Trustee nor any such agent shall be
affected by notice to the contrary.

     The CARAT Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the CARAT 2007-SN1 Noteholders under the CARAT
Indenture at any time by the Issuer with the consent of the Holders of CARAT
2007-SN1 Notes representing a majority of the Outstanding Amount of the
Controlling Class. The CARAT Indenture also contains provisions permitting the
Holders of CARAT 2007-SN1 Notes representing specified percentages of the
Outstanding Amount of the Controlling Class, on behalf of the Holders of all the
CARAT 2007-SN1 Notes, to waive compliance by the Issuer with certain provisions
of the CARAT Indenture and certain past defaults under the CARAT Indenture and
their consequences. Any such consent or waiver by the Holder of this CARAT
2007-SN1 Note (or any one of more Predecessor Notes) shall be conclusive and
binding upon such Holder and upon all future Holders of this CARAT 2007-SN1 Note
and of any CARAT 2007-SN1 Note issued upon the registration of transfer hereof
or in exchange hereof or in lieu hereof whether or not notation of such consent
or waiver


                                     C-4-8

is made upon this CARAT 2007-SN1 Note. The CARAT Indenture also permits the
CARAT Indenture Trustee to amend or waive certain terms and conditions set forth
in the CARAT Indenture without the consent of the Noteholders.

     The term "Issuer" as used in this CARAT 2007-SN1 Note includes any
successor to the Issuer under the CARAT Indenture.

     The Issuer is permitted by the CARAT Indenture, under certain
circumstances, to merge or consolidate, subject to the rights of the CARAT
Indenture Trustee and the Holders of CARAT 2007-SN1 Notes under the CARAT
Indenture.

     The CARAT 2007-SN1 Notes are issuable only in registered form in
denominations as provided in the CARAT Indenture, subject to certain limitations
therein set forth.

     THIS CARAT 2007-SN1 NOTE AND THE CARAT INDENTURE SHALL BE CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO
THE PRINCIPLES OF CONFLICTS OF LAWS THEREOF OR OF ANY OTHER JURISDICTION (OTHER
THAN SECTIONS 5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW), AND
THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER AND THEREUNDER
SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

     No reference herein to the CARAT Indenture and no provision of this CARAT
2007-SN1 Note or of the CARAT Indenture shall alter or impair the obligation of
the Issuer, which is absolute and unconditional, to pay the principal of and
interest on this CARAT 2007-SN1 Note at the times, place and rate, and in the
coin or currency herein prescribed.

     Anything herein to the contrary notwithstanding, except as expressly
provided in the CARAT Basic Documents, neither the Seller, the Trust
Administrator, the CARAT Indenture Trustee nor the CARAT Owner Trustee in their
respective individual capacities, any owner of a beneficial interest in the
Issuer, nor any of their respective partners, beneficiaries, agents, officers,
directors, employees or successors or assigns, shall be personally liable for,
nor shall recourse be had to any of them for, the payment of principal of or
interest on, or performance of, or omission to perform, any of the covenants,
obligations or indemnifications contained in this CARAT 2007-SN1 Note or the
CARAT Indenture, it being expressly understood that said covenants, obligations
and indemnifications have been made by the CARAT Owner Trustee solely as the
CARAT Owner Trustee in the assets of the Issuer. The Holder of this CARAT
2007-SN1 Note by the acceptance hereof agrees that, except as expressly provided
in the CARAT Basic Documents, in the case of a CARAT Event of Default under the
CARAT Indenture, the Holder shall have no claim against any of the foregoing for
any deficiency, loss or claim therefrom; provided, however, that nothing
contained herein shall be taken to prevent recourse to, and enforcement against,
the assets of the Issuer for any and all liabilities, obligations and
undertakings contained in the CARAT Indenture or in this CARAT 2007-SN1 Note.

                                 REVERSE OF NOTE

     This CARAT 2007-SN1 Note is one of a duly authorized issue of CARAT
2007-SN1 Notes of the Issuer, designated as its Class A-1 Fixed Rate Asset
Backed Notes (herein called the "[Class A-1a][Class A-1b] Notes"), all issued
under a CARAT Indenture, dated as of June 7, 2007 (such CARAT Indenture, as
supplemented or amended, is herein called the "CARAT Indenture"), between the
Issuer and The Bank of New York Trust Company, N.A., as trustee (the "CARAT
Indenture Trustee", which term includes any successor trustee under the CARAT
Indenture), to which CARAT Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights and
obligations thereunder of the Issuer, the CARAT Indenture Trustee and the CARAT
2007-SN1 Noteholders. The [Class A-1a][Class A-1b] Notes are one of several duly

CARAT Indenture (collectively, as to all CARAT 2007-SN1 Notes of all such

and subject to all terms of the CARAT Indenture (which terms are incorporated
herein and made a part hereof), to which CARAT Indenture the Holder of this
CARAT 2007-SN1 Note by virtue of acceptance hereof assents and by which such
Holder is bound. All capitalized terms used and not otherwise defined in this
CARAT 2007-SN1 Note that are defined in the CARAT Indenture, as supplemented or
amended, shall have the meanings assigned to them in or pursuant to the CARAT
Indenture.

     The [Class A-1a][Class A-1b] Notes and all other CARAT 2007-SN1 Notes
issued pursuant to the CARAT Indenture are and will be equally and ratably
secured by the Collateral pledged as security therefor as provided in the CARAT
Indenture.

     By acquiring a CARAT 2007-SN1 Note or any interest therein, each purchaser
and transferee will be deemed to represent and warrant that either (A) it is not

subject to the provisions of Title I of ERISA, (ii) a "plan" as described in
Section 4975(e)(1) of the Internal Revenue Code of 1986, as amended (the

of an employee benefit plan's or a plan's investment in the entity or (iv) other
plan subject to applicable law that is substantially similar to Section 406 of
ERISA or Section 4975 of the Code or (B) the acquisition, holding and
disposition of the CARAT 2007-SN1 Note will not give rise to a non-exempt
prohibited transaction under Section 406(a) of ERISA, Section 4975 of the Code
or a violation of any substantially similar applicable law.

     Each CARAT 2007-SN1 Noteholder or Note Owner, by acceptance of a CARAT
2007-SN1 Note or, in the case of a Note Owner, a beneficial interest in a CARAT
2007-SN1 Note, covenants and agrees that no recourse may be taken, directly or
indirectly, with respect to the obligations of the Issuer, the CARAT Owner
Trustee or the CARAT Indenture Trustee on the CARAT 2007-SN1 Notes or under the
CARAT Indenture or any certificate or other writing delivered in connection
therewith, against (i) the CARAT Indenture Trustee or the CARAT Owner Trustee in
their individual capacities, (ii) the Seller or any other owner of a beneficial
interest in the Issuer or (iii) any partner, owner, beneficiary, agent, officer,
director or employee of the CARAT Indenture Trustee or the CARAT Owner Trustee
in their individual capacities, any holder of a beneficial interest in the
Issuer, the CARAT Owner Trustee or the CARAT

<PAGE>

Indenture Trustee or of any successor or assign of the CARAT Indenture Trustee
or the CARAT Owner Trustee in their individual capacities, except as any such
Person may have expressly agreed and except that any such partner, owner or
beneficiary shall be fully liable, to the extent provided by applicable law, for
any unpaid consideration for stock, unpaid capital contribution or failure to
pay any instalment or call owing to such entity.

     Each CARAT 2007-SN1 Noteholder or Note Owner, by acceptance of a CARAT
2007-SN1 Note or, in the case of a Note Owner, a beneficial interest in a CARAT
2007-SN1 Note, covenants and agrees that by accepting the benefits of the CARAT
Indenture such CARAT 2007-SN1 Noteholder will not, prior to the date which is
one year and one day after the termination of the CARAT Indenture, acquiesce,
petition or otherwise invoke or cause the Seller or the Issuer to invoke the
process of any court or government authority for the purpose of commencing or
sustaining a case against the Seller or the Issuer under any federal or state
bankruptcy, insolvency or similar law or appointing a receiver, liquidator,
assignee, trustee, custodian, sequestrator or other similar official of the
Seller or the Issuer or any substantial part of its property, or ordering the
winding up or liquidation of the affairs of the Seller or the Issuer.

     Each CARAT 2007-SN1 Noteholder or Note Owner, by acceptance of a CARAT
2007-SN1 Note or, in the case of a Note Owner, a beneficial interest in a CARAT
2007-SN1 Note, expresses its intention that this CARAT 2007-SN1 Note qualifies
under applicable tax law as indebtedness secured by the Collateral and, unless
otherwise required by appropriate taxing authorities, agrees to treat the CARAT
2007-SN1 Notes as indebtedness secured by the Collateral for the purpose of
federal income taxes, state and local income and franchise taxes, Michigan
single business tax, and any other taxes imposed upon, measured by or based upon
gross or net income.

     Prior to the due presentment for registration of transfer of this CARAT
2007-SN1 Note, the Issuer, the CARAT Indenture Trustee and any agent of the
Issuer or the CARAT Indenture Trustee may treat the Person in whose name this
CARAT 2007-SN1 Note (as of the day of determination or as of such other date as
may be specified in the CARAT Indenture) is registered as the owner hereof for
all purposes, whether or not this CARAT 2007-SN1 Note shall be overdue, and
neither the Issuer, the CARAT Indenture Trustee nor any such agent shall be
affected by notice to the contrary.

     The CARAT Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the CARAT 2007-SN1 Noteholders under the CARAT
Indenture at any time by the Issuer with the consent of the Holders of CARAT
2007-SN1 Notes representing a majority of the Outstanding Amount of the
Controlling Class. The CARAT Indenture also contains provisions permitting the
Holders of CARAT 2007-SN1 Notes representing specified percentages of the
Outstanding Amount of the Controlling Class, on behalf of the Holders of all the
CARAT 2007-SN1 Notes, to waive compliance by the Issuer with certain provisions
of the CARAT Indenture and certain past defaults under the CARAT Indenture and
their consequences. Any such consent or waiver by the Holder of this CARAT
2007-SN1 Note (or any one of more Predecessor Notes) shall be conclusive and
binding upon such Holder and upon all future Holders of this CARAT 2007-SN1 Note
and of any CARAT 2007-SN1 Note issued upon the registration of transfer hereof
or in exchange hereof or in lieu hereof whether or not notation of such consent
or waiver


                                     C-5-7

is made upon this CARAT 2007-SN1 Note. The CARAT Indenture also permits the
CARAT Indenture Trustee to amend or waive certain terms and conditions set forth
in the CARAT Indenture without the consent of the Noteholders.

     The term "Issuer" as used in this CARAT 2007-SN1 Note includes any
successor to the Issuer under the CARAT Indenture.

     The Issuer is permitted by the CARAT Indenture, under certain
circumstances, to merge or consolidate, subject to the rights of the CARAT
Indenture Trustee and the Holders of CARAT 2007-SN1 Notes under the CARAT
Indenture.

     The CARAT 2007-SN1 Notes are issuable only in registered form in
denominations as provided in the CARAT Indenture, subject to certain limitations
therein set forth.

     THIS CARAT 2007-SN1 NOTE AND THE CARAT INDENTURE SHALL BE CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO
THE PRINCIPLES OF CONFLICTS OF LAWS THEREOF OR OF ANY OTHER JURISDICTION (OTHER
THAN SECTIONS 5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW), AND
THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER AND THEREUNDER
SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

     No reference herein to the CARAT Indenture and no provision of this CARAT
2007-SN1 Note or of the CARAT Indenture shall alter or impair the obligation of
the Issuer, which is absolute and unconditional, to pay the principal of and
interest on this CARAT 2007-SN1 Note at the times, place and rate, and in the
coin or currency herein prescribed.

     Anything herein to the contrary notwithstanding, except as expressly
provided in the CARAT Basic Documents, neither the Seller, the Trust
Administrator, the CARAT Indenture Trustee nor the CARAT Owner Trustee in their
respective individual capacities, any owner of a beneficial interest in the
Issuer, nor any of their respective partners, beneficiaries, agents, officers,
directors, employees or successors or assigns, shall be personally liable for,
nor shall recourse be had to any of them for, the payment of principal of or
interest on, or performance of, or omission to perform, any of the covenants,
obligations or indemnifications contained in this CARAT 2007-SN1 Note or the
CARAT Indenture, it being expressly understood that said covenants, obligations
and indemnifications have been made by the CARAT Owner Trustee solely as the
CARAT Owner Trustee in the assets of the Issuer. The Holder of this CARAT
2007-SN1 Note by the acceptance hereof agrees that, except as expressly provided
in the CARAT Basic Documents, in the case of a CARAT Event of Default under the
CARAT Indenture, the Holder shall have no claim against any of the foregoing for
any deficiency, loss or claim therefrom; provided, however, that nothing
contained herein shall be taken to prevent recourse to, and enforcement against,
the assets of the Issuer for any and all liabilities, obligations and
undertakings contained in the CARAT Indenture or in this CARAT 2007-SN1 Note.

            QUALIFIED INSTITUTIONAL BUYER STATUS UNDER SEC RULE 144A

          [for Transferees other than Registered Investment Companies]

The undersigned hereby certifies as follows to [name of Transferor] (the
"Transferor") and [name of Note Registrar], as Note Registrar, with respect to
the Class A-1 Notes being transferred (the "Transferred Notes") as described in
the Transferee Certificate to which this certification relates and to which this
certification is an Annex:

1. As indicated below, the undersigned is the chief financial officer, a person
fulfilling an equivalent function, or other executive officer of the entity

     Columbia, the business of which is substantially confined to banking and is

     official or is a foreign bank or equivalent institution, and (b) has an
     audited net worth of at least $25,000,000 as demonstrated in its latest

     case of a U.S. bank, and not more than 18 months preceding such date of
     sale for a foreign bank or equivalent institution.

[ ]  Savings and Loan. The Transferee (a) is a savings and loan association,
     building and loan association, cooperative bank, homestead association or
     similar institution, which is supervised and examined by a State or Federal
     authority having supervision over any such institutions or is a foreign

     audited net worth of at least $25,000,000 as demonstrated in its latest
     annual financial statements, a copy of which is attached hereto, as of a
     date not more than 16 months preceding the date of sale of the Note in


                                     D-2-2

<PAGE>

     the case of a U.S. savings and loan association, and not more than 18
     months preceding such date of sale for a foreign savings and loan
     association or equivalent institution.

[ ]  Broker-dealer. The Transferee is a dealer registered pursuant to Section
     15 of the Securities Exchange Act of 1934, as amended.

[ ]   Insurance Company. The Transferee is an insurance company whose primary
     and predominant business activity is the writing of insurance or the
     reinsuring of risks underwritten by insurance companies and which is
     subject to supervision by the insurance commissioner or a similar official
     or agency of a State, U.S. territory or the District of Columbia.

[ ]  State or Local Plan. The Transferee is a plan established and maintained
     by a State, its political subdivisions, or any agency or instrumentality of
     the State or its political subdivisions, for the benefit of its employees.

[ ]  ERISA Plan. The Transferee is an employee benefit plan within the meaning
     of Title I of the Employee Retirement Income Security Act of 1974, as
     amended.

[ ]  Investment Advisor. The Transferee is an investment advisor registered
     under the Investment Advisers Act of 1940, as amended.

[ ]  Other. (Please supply a brief description of the entity and a
     cross-reference to the paragraph and subparagraph under subsection (a)(1)
     of Rule l44A pursuant to which it qualifies. Note that registered
     investment companies should complete Annex 2 rather than this Annex 1.)

3. The term "securities" as used herein does not include (i) securities of
issuers that are affiliated with the Transferee, (ii) securities that are part
of an unsold allotment to or subscription by the Transferee, if the Transferee
is a dealer, (iii) bank deposit notes and certificates of deposit, (iv) loan
participations, (v) repurchase agreements, (vi) securities owned but subject to
a repurchase agreement and (vii) currency, interest rate and commodity swaps.
For purposes of determining the aggregate amount of securities owned and/or
invested on a discretionary basis by the Transferee, the Transferee did not
include any of the securities referred to in this paragraph.

4. For purposes of determining the aggregate amount of securities owned and/or
invested on a discretionary basis by the Transferee, the Transferee used the
cost of such securities to the Transferee, unless the Transferee reports its
securities holdings in its financial statements on the basis of their market
value, and no current information with respect to the cost of those securities
has been published, in which case the securities were valued at market. Further,
in determining such aggregate amount, the Transferee may have included
securities owned by subsidiaries of the Transferee, but only if such
subsidiaries are consolidated with the Transferee in its financial statements
prepared in accordance with generally accepted accounting principles and if the
investments of such subsidiaries are managed under the Transferee's direction.
However, such


                                     D-2-3

<PAGE>

securities were not included if the Transferee is a majority-owned, consolidated
subsidiary of another enterprise and the Transferee is not itself a reporting
company under the Securities Exchange Act of 1934, as amended.

5. The Transferee acknowledges that it is familiar with Rule l44A and
understands that the Transferor and other parties related to the Transferred
Notes are relying and will continue to rely on the statements made herein
because one or more sales to the Transferee may be in reliance on Rule 144A.

[ ] [ ] Will the Transferee be purchasing the Transferred Notes only for the
Yes No  Transferee's own account?

6. If the answer to the foregoing question is "no", then in each case where the

                                                          ANNEX 2 TO EXHIBIT D-2

            QUALIFIED INSTITUTIONAL BUYER STATUS UNDER SEC RULE 144A

           [for Transferees that are Registered Investment Companies]

The undersigned hereby certifies as follows to [name of Transferor] (the
"Transferor") and [name of Note Registrar], as Note Registrar, with respect to
the Class A-1 Notes being transferred (the "Transferred Notes") as described in
the Transferee Certificate to which this certification relates and to which this
certification is an Annex:

1. As indicated below, the undersigned is the chief financial officer, a person
fulfilling an equivalent function, or other executive officer of the entity
purchasing the Transferred Certificates (the "Transferee") or, if the Transferee
is a "qualified institutional buyer" as that term is defined in Rule 144A under
the Securities Act of 1933, as amended ("Rule 144A"), because the Transferee is
part of a Family of Investment Companies (as defined below), is an executive
officer of the investment adviser (the "Adviser").

2. The Transferee is a "qualified institutional buyer" as defined in Rule 144A
because (i) the Transferee is an investment company registered under the
Investment Company Act of 1940, as amended, and (ii) as marked below, the
Transferee alone owned and/or invested on a discretionary basis, or the
Transferee's Family of Investment Companies owned, at least $100,000,000 in
securities (other than the excluded securities referred to below) as of the end
of the Transferee's most recent fiscal year. For purposes of determining the
amount of securities owned by the Transferee or the Transferee's Family of
Investment Companies, the cost of such securities was used, unless the
Transferee or any member of the Transferee's Family of Investment Companies, as
the case may be, reports its securities holdings in its financial statements on
the basis of their market value, and no current information with respect to the
cost of those securities has been published, in which case the securities of
such entity were valued at market.

     [ ]  The Transferee owned and/or invested on a discretionary basis
          $____________ in securities (other than the excluded securities
          referred to below) as of the end of the Transferee's most recent
          fiscal year (such amount being calculated in accordance with Rule
          144A).

     [ ]  The Transferee is part of a Family of Investment Companies which owned
          in the aggregate $_____________ in securities (other than the excluded
          securities referred to below) as of the end of the Transferee's most
          recent fiscal year (such amount being calculated in accordance with
          Rule 144A).

3. The term "Family of Investment Companies" as used herein means two or more
registered investment companies (or series thereof) that have the same
investment adviser or I investment advisers that are affiliated (by virtue of
being majority owned subsidiaries of the same parent or because one investment
adviser is a majority owned subsidiary of the other).


                                     D-2-5

<PAGE>

4. The term "securities" as used herein does not include (i) securities of
issuers that are affiliated with the Transferee or are part of the Transferee's
Family of Investment Companies, (ii) bank deposit notes and certificates of
deposit, (iii) loan participations, (iv) repurchase agreements, (v) securities
owned but subject to a repurchase agreement and (vi) currency, interest rate and
commodity swaps. For purposes of determining the aggregate amount of securities
owned and/or invested on a discretionary basis by the Transferee, or owned by
the Transferee's Family of Investment Companies, the securities referred to in
this paragraph were excluded.

5. The Transferee is familiar with Rule 144A and understands that the parties to
which this certification is being made are relying and will continue to rely on
the statements made herein because one or more sales to the Transferee will be
in reliance on Rule 144A.

[ ] [ ] Will the Transferee be purchasing the Transferred Notes only for the
Yes No  Transferee's own account?

6. If the answer to the foregoing question is "no", then in each case where the
Transferee is purchasing for an account other than its own, such account belongs
to a third party that is itself a "qualified institutional buyer" within the
meaning of Rule 144A, and the "qualified institutional buyer" status of such
third party has been established by the Transferee through one or more of the
appropriate methods contemplated by Rule l44A.

7. The undersigned will notify the parties to which this certification is made
of any changes in the information and conclusions herein. Until such notice, the
Transferee's purchase of the Transferred Notes will constitute a reaffirmation
of this certification by the undersigned as of the date of such purchase.
