           RE:      Confirmation of Primary Swap Relating to the Class A-4 Notes

Dear Ladies and Gentlemen:

         The purpose of this letter agreement is to confirm the terms and
conditions of the Swap Transaction (the "Primary Swap") entered into between
Deutsche Bank AG New York branch (the "Counterparty"), and Capital Auto
Receivables Asset Trust 2002-3 (the "Trust") as of the Trade Date listed below
(the "Transaction"). This letter constitutes a "Confirmation" as referred to in
the Primary ISDA Agreement specified below.

1.       The definitions and provisions contained in the 2000 ISDA Definitions
         (the "Definitions"), as published by the International Swaps and
         Derivatives Association, Inc. ("ISDA"), are incorporated into this
         Confirmation. In the event of any inconsistency between those
         definitions and provisions and this Confirmation, this Confirmation
         will govern. The parties agree that this transaction is a Transaction
         under the ISDA Master Agreement of the parties, dated as of August 8,
         2002. The agreement is comprised of the printed form of such agreement
         as published by ISDA, as supplemented and modified by a Schedule (the
         "Primary ISDA Agreement").

         This Confirmation constitutes a binding agreement between you and us
         and will supplement, form a part of, and be subject to the Primary ISDA
         Agreement described above as amended and supplemented from time to
         time.

         relates to the Class A-4 Floating Rate Asset Backed Notes (the
         "Reference Notes") issued by the Trust for value pursuant to and
         subject to the Indenture.

         Capitalized terms used and not otherwise defined herein, in the Primary
         ISDA Agreement or in the Definitions shall have the meanings assigned

                  Offsetting Counterparty shall promptly notify the Trust (and
                  any permitted assignee or transferee of the Trust) and the
                  Counterparty of such event and (unless, within thirty (30)
                  days after such reduction, the applicable Rating Agency has
                  reconfirmed the ratings of the Reference Notes and the Other
                  Securities that were in effect immediately prior to such
                  reduction) the Counterparty shall within thirty (30) days of
                  receipt of notice of such reduction, with the prior written
                  confirmation of the applicable Rating Agency that such
                  arrangement will not result in the reduction of the rating of
                  any of the Reference Notes or the Other Securities existing
                  immediately prior to the reduction of the applicable Joint
                  Probability, either:

                  (i)      obtain a substitute swap provider (the "Substitute
                           Swap Provider") acceptable to the Trust (such
                           acceptance not to be unreasonably withheld) and
                           replace this Transaction with a swap transaction on
                           substantially similar terms or with such other
                           amendments as consented to in writing by the Trust
                           (which consent shall not be unreasonably withheld),
                           provided such replacement would result in an S&P
                           Joint Probability of at least AA- and a Moody's Joint
                           Probability of at least Aa3a; or

                  (ii)     enter into an ISDA Credit Support Annex with the
                           Trust mutually acceptable to the Trust and the
                           Counterparty; or

                  (iii)    enter into such other credit support arrangements to
                           assure performance by the Counterparty of its
                           obligations under this Transaction.

         (b)      At any time within thirty (30) days of receipt of notice of
                  the reduction of the applicable Joint Probability, the
                  Counterparty may provide the Trust and the Offsetting
                  Counterparty a written request that (a) the Trust and the
                  Offsetting Counterparty terminate the Fallback Swap
                  Transaction and (b) the Trust enter into a replacement swap
                  transaction (the "Replacement Fallback Swap Transaction") with
                  another party identified (by the Counterparty at its own
                  expense) in the written request (the "Replacement Offsetting
                  Counterparty") on terms substantially the same as the Fallback
                  Swap Transaction; provided that the Replacement Fallback Swap
                  Transaction and the Replacement Offsetting Counterparty would
                  result in an S&P Joint Probability Rating of at least AA- and
                  a Moody's Joint Probability of a least Aa3. To the extent the
                  Trust and Offsetting Counterparty, in their sole and absolute
                  discretion, terminate the Fallback Swap Transaction and the
                  Trust, in its sole and absolute discretion, enters into the
                  Replacement Fallback Swap Transaction with the Fallback
                  Offsetting Counterparty, in each case, within thirty (30) days
                  of receipt of notice of the reduction of the Joint
                  Probability, the Counterparty will have no further obligations
                  under paragraph (a) above.

         (c)      Notwithstanding paragraphs (a) and (b) above, in the event
                  that the Joint Probability is reduced below A- in the case of
                  S&P, or A3, in the case of Moody's, the Offsetting
                  Counterparty shall promptly notify the Trust (and any
                  permitted assignee or transferee of the Trust) and the
                  Counterparty of such event and (unless, within thirty (30)
                  days after such reduction the applicable Rating Agency has
                  reconfirmed the ratings of the Reference Notes and the Other
                  Securities that were in effect immediately prior to such
                  reduction) the Counterparty shall within thirty (30) days of
                  receipt of notice of such reduction, with the prior written
                  confirmation of the applicable Rating Agency that such
                  arrangement will not result in the reduction of the rating of
                  any of the Reference Notes or the Other Securities existing
                  immediately prior to the reduction of the applicable Joint
                  Probability as a direct result of the reduction of such Joint
                  Probability, obtain a Substitute Swap Provider acceptable to
                  the Trust (such acceptance not to be unreasonably withheld)
                  and replace this Transaction with a swap transaction on
                  substantially similar terms or with such other

                                       3



                  amendments as consented to in writing by the Trust (which
                  consent shall not be unreasonably withheld); provided such
                  replacement would result in an S&P Joint Probability of at
                  least AA- or a Moody's Joint Probability of Aa3.

         (d)      Upon any replacement of this Transaction with a swap
                  transaction with a Substitute Swap Provider, who thenceforth
                  shall be the "Counterparty" hereunder, this Transaction shall
                  terminate without any payment by either party hereto and any
                  and all collateral posted by the Counterparty shall be
                  returned to it within three (3) Business Days and any other
                  form of collateral arrangement (including letters of credit,
                  surety bond or other guarantee) provided by or on behalf of
                  the Counterparty shall terminate.

         (e)      In the event that the Counterparty fails to satisfy its
                  obligations set forth above in this Section 4, the Trust or
                  any permitted assignee or transferee of the Trust shall have
                  the option, exercisable in its discretion and with regard to
                  the interests of the Noteholders, within ten (10) Business
                  Days following the date of expiry of the thirty (30) day
                  period after receipt of notice of the reduction (unless,
                  within thirty (30) days of receipt of notice of such
                  reduction, the applicable Rating Agency has reconfirmed the
                  rating of the Reference Notes that was in effect immediately
                  prior to such reduction), to designate (in writing) an Early
                  Termination Date on the basis that such failure shall be
                  treated as a Termination Event with the Counterparty as the
                  Affected Party. For the avoidance of doubt, the Counterparty
                  and the Trust acknowledge and agree that any such failure
                  shall not constitute an Event of Default.

                                    EXHIBIT A

The following terms shall have the following meanings in this Confirmation:

     "Determination Date": the tenth (10th) day of each calendar month, or if
such tenth (10th) day is not a Business Day, the next succeeding Business Day.

     "Distribution Date": the fifteenth (15th) day of each succeeding calendar
month following the Effective Date or, if such fifteenth (15th) day is not a
Business Day, the next such succeeding Business Day, commencing September 16,
2002.

     "Indenture": the Indenture, dated as August 8, 2002, between the Trust and
the Indenture Trustee, as amended and supplemented from time to time in
accordance with its terms.

     "Indenture Trustee": Bank One, National Association, not in its individual
capacity but solely as trustee under the Indenture, or any successor trustee
under the Indenture.

     "LIBOR": with respect to each Floating Rate Payer Payment Date, the rate
for deposits in U.S. Dollars for a period of one month which appears on the
Telerate Service Page 3750 as of 11:00 a.m., London time, on the day that is two
LIBOR Business Days prior to the Distribution Date (or, in the case of the
initial Floating Rate Payer Payment Date, two LIBOR Business Days prior to
Closing Date) preceding such Floating Rate Payer Payment Date. If the rate does
not appear on that date on the Telerate Service Page 3750 (or any other page as
may replace that page on that service, or if that service is no longer offered,
any other service for displaying LIBOR or comparable rates as may be selected by
the Indenture Trustee after consultation with the Seller), then LIBOR will be
the Reference Bank Rate.

     "LIBOR Business Day": any day other than a Saturday, Sunday or any other
day on which banks in London are required or authorized to be closed.

     "Other Securities": Class A-1, Class A-2a, Class A-2b and Class A-3 Notes
and Certificates issued by the Trust.

     "Reference Bank Rate": for any Floating Rate Payer Payment Date, the per
annum rate determined on the basis of the rates at which deposits in U.S.
Dollars are offered by the reference banks (which will be four major banks that
are engaged in transactions in the London interbank market, selected by the
Calculation Agent) as of 11:00 a.m., London time, on the day that is two LIBOR
Business Days prior to the Distribution Date preceding such Floating Rate Payer
Payment Date to prime banks in the London interbank market for a period of one
month, in amounts approximately equal to the principal amount of the Reference
Notes then outstanding. The Calculation Agent will request the principal London
office of each of the reference banks to provide a quotation of its rate. If at
least two quotations are provided, the rate will be the arithmetic mean of the
