         WHEREAS, pursuant to the Purchase and Sale Agreement, the Purchasers
have agreed to purchase, and have purchased, certain Receivables from the
Seller;

         WHEREAS, the Seller has requested that the Purchasers, the Managing
Facility Agent and the Co-Administrative Agents amend the Purchase and Sale
Agreement in certain ways; and

         WHEREAS, the Purchasers, the Seller, the Servicer, the Managing
Facility Agent, the Co-Administrative Agents, RAC and Raytheon desire to amend
the Purchase and Sale Agreement in the manner specified herein.

         NOW, THEREFORE, the parties hereto hereby agree as follows:

                  1. Defined Terms. Terms defined in the Purchase and Sale
Agreement and used herein shall have the meanings given to them in the Purchase
and Sale Agreement.

                  2. Amendments to Subsection 1.1 of the Purchase and Sale
Agreement. (a) Subsection 1.1 of the Purchase and Sale Agreement is hereby
amended by deleting therefrom the definitions of the following defined terms in
their respective entireties and inserting in lieu thereof the following new
definitions in their proper alphabetical position:

                                       2

                  "Consolidated Net Income": for any period, the consolidated
net income (or deficit) of Raytheon and its consolidated Subsidiaries for such
period, determined in accordance with GAAP; provided that (i) for the fiscal
quarter of Raytheon and its consolidated Subsidiaries ending December 31, 1997,
such Consolidated Net Income shall be increased by $327,100,000 representing a
restructuring charge taken in connection with Raytheon's acquisition of Hughes
Aircraft Company, (ii) for the fiscal quarter of Raytheon and its consolidated
Subsidiaries ending September 27, 1998, such Consolidated Net Income shall be
increased by $284,000,000 representing restructuring charges and a write-down in
investments taken in such fiscal quarter and (iii) for the fiscal quarter of
Raytheon and its consolidated Subsidiaries ending October 3, 1999, such
Consolidated Net Income shall be increased by $144,000,000 representing
restructuring charges and other non-recurring charges.

                  "Debt Rating":  at any date of determination, Raytheon's
long-term unsecured senior debt rating, determined in accordance with the
following:

         (a) for purposes of determining Debt Rating as used in the definition
of "Rating Adjustment",

(i) if on any date on which a Debt Rating is to be determined, only two of
Moody's, S&P and Duff are providing long-term unsecured senior debt ratings for
Raytheon and such ratings are no more than one rating level apart (e.g., the
difference between B and B+ being one rating level), the Debt Rating will be the
lower of such ratings,

(ii) if on any date on which a Debt Rating is to be determined, only two of
Moody's, S&P and Duff are providing long-term unsecured senior debt ratings for
Raytheon but such ratings are more than one rating level apart, the Debt Rating
will be one rating level higher than the lower of such ratings so provided,

(iii) if on any date on which a Debt Rating is to be determined, each of
Moody's, S&P and Duff is providing long-term unsecured senior debt ratings for
Raytheon, the Debt Rating will be the lower of the two highest of the three
ratings so provided, and

(iv) if on any date on which a Debt Rating is to be determined, only one of
Moody's, S&P and Duff is providing a long-term unsecured senior debt rating for
Raytheon, the Debt Rating will be Raytheon's long-term unsecured senior debt
rating as provided by such rating agency; and

         (b) for all other purposes, if on any date on which a Debt Rating is to
be determined, any one, two or all three of Moody's, S&P and Duff are providing
long-term unsecured senior debt ratings for Raytheon, the Debt Rating will be
the lowest of the ratings (or the rating, in the case of a rating by only one of
Moody's, S&P and Duff) so provided.

A debt rating shall be deemed to be in effect on the date of announcement or
publication by the applicable rating agency. References in this Agreement to
alphabetical rating classifications are references to the S&P/Moody's ratings.
For purposes of clauses (a) and (b) above, the ratings of Duff shall be the
rating provided by Duff which is comparable to the S&P alphabetical
classification. Notwithstanding the foregoing, the Seller and the Required
Purchasers may at any time and from time to time agree to utilize a rating
agency other than Moody's, S&P or Duff to determine the Debt Rating, in which
case the Debt Rating shall be such levels as quoted by such rating agencies as,
in each case, the Seller and the Purchasers, by unanimous consent, shall agree.

                  "Discount Event":  any time on or prior to the Expiration
Date when Raytheon's Debt Rating is lower than either BBB- or the equivalent
thereof.

                                       3

                  "Rating Adjustment": the increase in (i) the Applicable Margin
for any Accrual Period and (ii) the Interbank Rate applicable for any Special
Settlement Date Accrual Period, as applicable, to be applied if Raytheon's Debt
Rating is at the levels set forth below on the last day of the immediately
preceding Accrual Period:
                                                       Applicable Margin and
                  Debt Rating                          Interbank Rate Increase

                  A+ or A1                                    .030%
                  A or A2                                     .065%
                  A- or A3                                    .100%
                  BBB+ or Baa1                                .125%
                  BBB or Baa2                                 .225%
                  below BBB or Baa2 or not rated              .500%

                  "Rating Event": any time when (a) Raytheon's Debt Rating is
below BBB- or the equivalent thereof, or if for any reason Raytheon's long-term
senior unsecured debt is not rated (whether by reason of suspension or
withdrawal of a rating, or otherwise) or (b) an Amortization Event described in
subsection 8.1(o) shall have occurred and be continuing.

                  "Remittance Event":  any time Raytheon's Debt Rating is below
BBB- or the equivalent thereof, or if for any reason Raytheon's long-term senio
unsecured debt is not rated (whether by reason of suspension or withdrawal of a
rating, or otherwise).

                  (b) Clause (t) of the definition of "Eligible Receivables" is
hereby amended by deleting the phrase "BBB/Baa2" appearing therein and by
inserting, in lieu thereof, the phrase "BBB- or the equivalent thereof".

               3. Amendments to Subsection 2.7 of the Purchase and Sale
Agreement. Subsection 2.7 of the Purchase and Sale Agreement is hereby amended
by deleting the phrase "BBB/Baa2" in clause (viii) and "BBB or Baa2" in clause
(xvi) and by inserting, in lieu thereof in each such clause, the phrase "BBB- or
the equivalent thereof".

               4. Amendments to Subsection 8.1 of the Purchase and Sale
Agreement. Subsection 8.1 of the Purchase and Sale Agreement is hereby amended
by deleting paragraph (h) thereof and inserting in lieu thereof the following
paragraph:

                  "(h) as of the last day of any of Raytheon's fiscal quarters
ending on or prior to the Expiration Date, the Interest Coverage Ratio for the
period of four consecutive fiscal quarters then ending shall be less than 2.4 to
1.0 for such four-quarter period."

               5.  Affirmation of Repurchase Agreement. RAC hereby consents to
the amendments to the Purchase and Sale Agreement set forth herein and reaffirms

               6. Affirmation of Guarantee. The Guarantor hereby consents to

               7.  Conditions to Effectiveness. This Amendment shall become
effective on the date (the "Amendment Effective Date") on which the Seller, the
Servicer, RAC, Raytheon, the Managing Facility Agent, each Co-Administrative
Agent and the Required Purchasers shall have executed and delivered this
Amendment to the Managing Facility Agent.

                                       4
