                  "(1)     If an Illegality, a Tax Event or a Tax Event Upon
                  Merger occurs, if the Counterparty is the Affected Party it
                  will, and if the Trust is the Affected Party it may request
                  the Counterparty to (and the Counterparty upon notice thereof
                  will), use its best efforts (provided that using its best
                  efforts will not require the Counterparty to incur any loss,
                  excluding immaterial, incidental expenses) to transfer prior
                  to the 20th day following the occurrence of such event (the
                  "TRANSFER CUT-OFF DATE"), all of its rights and obligations
                  under this Agreement in respect of Affected Transactions to
                  another of its offices or affiliates or third party so that
                  such Termination Event ceases to exist.

                  If the Counterparty is not able to make such a transfer it
                  will give notice to the Trust to that effect prior to the
                  Transfer Cut-Off Date.

                  Any such transfer under this Section 6(b)(ii) will be subject
                  to and conditional upon the prior written consent of the
                  Trust, which consent will not be withheld if the Trust's
                  policies in effect at such time would permit it to enter into
                  transactions with the transferee on the terms proposed and may
                  not be refused if it is pursuant to the Triparty Agreement.

                  (2)      No transfer or substitution pursuant to this Section
                  6(b)(ii) shall occur if (x) the then current ratings of the
                  Class A Notes by Moody's Investors Service ("Moody's") or
                  Standard & Poor's Rating Services ("S&P") would be reduced or
                  adversely affected or (y) the position of the Trust would

                  or substitution)"

                  (v)      Section 6(b)(iii) shall hereby be amended by
         replacing the words "within 30 days" with the words "by the Transfer
         Cut-Off Date (as defined above)."

                  (vi)     Section 6(b)(iv) is hereby deleted and the following
         shall be inserted in its place:

                  the case may be, has not been effected with respect to all
                  Affected Transactions by the Transfer Cut-Off Date, an Early
                  Termination Date in respect of all outstanding Swap
                  Transactions will occur immediately."

provision: "provided however, that, the Counterparty consents to the pledge and
assignment by the Trust of the Trust's rights and interests hereunder pursuant
to the Indenture; provided further that the Counterparty may make such a
transfer to another of its affiliates, offices, or branches, on ten Business
Days' prior written notice to the Trust, provided that:

                  (i)      no such transfer shall occur if the then current

                  (ii)     the Counterparty delivers an opinion of independent
                  counsel of recognized standing, in form and substance

                  and

                  (iii)    such transfer will not cause the occurrence of an
                  Event of Default or a Termination Event under this Agreement.

                  Notwithstanding the foregoing, prior written notice of
         transfer shall not be required with respect to a transfer under Section
         6(b)(ii).

                           "eligible contract participant" as that term is
                           defined in Section 1a(12) of the Commodity Exchange
                           Act, as amended by the Commodity Futures

                           this Agreement and it is entering into the
                           Transaction in connection with its line of business
                           (including financial intermediation services) or the
                           financing of its business; and the material terms of
                           this Agreement and the Transaction have been
                           individually tailored and negotiated.

         (g)      Amendments. Section 9(b) of this Agreement is hereby amended
by adding the following:

                           ; provided, however, that no such amendments,
                           modifications or waivers shall be effective until
                           such time as the Trust has obtained the written
                           affirmation of each of Moody's and S&P, who are then
                           rating any securities issued by the Trust that such
                           amendments, modifications or waivers shall not
                           adversely affect the then current ratings of the
                           Class A Notes.

         (h)      Confirmations. Each Confirmation supplements, forms part of,
and will be read and construed as one with this Agreement.

         (i)      Capitalized Terms. Each capitalized term used in this
Agreement and not defined in this Agreement, the Confirmation or the Definitions
shall have the meaning given such term in Appendix A to the Trust Sale and
Servicing Agreement, dated as of March 2, 2004, among GMAC, as Servicer, Capital
Auto Receivables, Inc., as Seller, and Capital Auto Receivables Asset Trust
2004-1 as Issuer (as amended, modified or supplemented from time to time in
accordance with its terms). To the extent that a capitalized term in this
Agreement is defined by reference to a related definition contained in the Trust
Sale and Servicing Agreement, the Indenture, the Pooling and Servicing
Agreement, the Swap Counterparty Rights Agreement, the Administration Agreement,
the Trust Agreement and the Custodian Agreement (the "Trust Documents"), for
purposes of this Agreement only, such capitalized term shall be deemed to be
amended only if the amendment of the term in a Trust Document relating to such
capitalized term occurs with the prior written consent of the Counterparty.

         (j)      No Set-Off. Without affecting the provisions of this Agreement
requiring the calculation of certain net payment amounts, all payments under
this Agreement will be made without set-off or counterclaims.

         (k)      Liability to Trustee. It is expressly understood and agreed by
the parties hereto that (a) this Agreement is executed and delivered by Deutsche
Bank Trust Company Delaware, not individually or personally but solely as
trustee of the Trust, in the exercise of the powers and authority conferred and
vested in it under the Trust Agreement, (b) each of the representations,
undertakings and agreements herein made on the part of the Trust is made and
intended not as personal representations, undertakings and agreements by
Deutsche Bank Trust Company Delaware but is made and intended for the purpose of
binding only the Trust and (c) under no circumstances shall Deutsche Bank Trust
Company Delaware be personally liable for the payment of any indebtedness or
expenses of the Trust or be liable for the breach or failure of any obligation,
representation, warranty or covenant made or undertaken by the Trust under this
Agreement or the other Basic Documents. For all purposes of this Agreement, in
the performance of any duties or obligations of the Trust or the Owner Trustee
hereunder, the Owner Trustee shall be entitled to the benefits of the terms and
provisions of the Trust Agreement.

         (l)      Severability. In the event that any one or more of the
provisions contained in this Agreement should be held invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions in the Agreement shall not in any way be affected or
impaired. In the event that any one or more of the provisions contained in this
Agreement should be held invalid, illegal or unenforceable, the parties will
negotiate in good faith to replace the invalid, illegal or unenforceable
provisions with valid provisions which will, as nearly as possible, give the
originally intended legal and economic effect of the invalid, illegal or
unenforceable provisions.

         (m)      No-Petition. The Counterparty hereby agrees that it will not,
prior to the date which is one year and one day after all Notes issued by the
Trust pursuant to the Indenture have been paid in full, acquiesce, petition or
otherwise invoke, or cause or encourage any Person,

                                       10

purpose of appointing a receiver, liquidator, assignee, trustee, custodian,
sequestrator or other similar official for the Trust or any substantial part of
the property of the Trust, or for the purpose of ordering the winding up or
liquidation of the affairs of the Trust. Nothing herein shall prevent the
Counterparty from participating in any such proceeding once commenced.

         IN WITNESS WHEREOF, the parties have executed this Schedule by their
