            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

            notice to the Trust to that effect prior to the Transfer Cut-Off
            Date.

            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 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 otherwise materially be prejudiced

                                       3


            under this Agreement or any Confirmation (it being understood that
            it shall be the responsibility of the Trust to verify such matters
            prior to the occurrence of such transfer or substitution)"

      inserted in its place:

            If a Termination Event has occurred and a transfer under Section
            6(b)(ii) or an agreement under Section 6(b)(iii), as 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."

any other swap transactions after the date hereof which provide for payments
upon termination that are senior to or pari passu with any payment due under any

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

Days' prior written notice to the Trust, provided that:

            (i) no such transfer shall occur if the then current ratings of the
            Notes by Moody's or S&P would be reduced or adversely affected;

            (ii) the Counterparty delivers an opinion of independent counsel of
            recognized standing, in form and substance reasonably satisfactory
            to the Indenture Trustee and the Servicer, confirming that as of the
            date of such transfer the transferee will not, as a result of such
            transfer, be required to withhold or deduct on account of Tax under
            this Agreement; 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).

      (f) Additional Representations. Section 3 is hereby amended by adding at
the end thereof the following Subparagraphs:

                  (g) ELIGIBLE CONTRACT PARTICIPANT. It is an "eligible contract
                  participant" as that term is defined in Section 1a(12) of the
                  Commodity Exchange Act, as amended by the Commodity Futures
                  Modernization Act of 2000, and it has entered into 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 Notes.

                                       9


      (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 December 9, 2004, among GMAC, as Servicer, Capital Auto
Receivables, Inc., as Seller, and Capital Auto Receivables Asset Trust 2004-2 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


including the Trust, to invoke, the process of any court or governmental
authority for the purpose of commencing or sustaining a case against the Trust
under any federal or state bankruptcy, insolvency or similar law or for the
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.

                                       11


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