                                Raytheon Company
                      Change In Control Severance Agreement

     Agreement by and between Raytheon Company, a Delaware corporation (the
"Company"), and                  ("Executive") dated as of                 ,
                ----------------                           ----------------
2001.

     The Board of Directors of Company believes it is in the best interests of
the Company and its stockholders to have the continued dedication of Executive
notwithstanding the possibility, threat or occurrence of a Change in Control (as
defined in Section 1.5); to diminish the inevitable distraction of Executive due
to personal uncertainties and risks created by a threatened or pending Change in
Control; and to provide Executive with compensation and benefits arrangements
upon a Change in Control which are competitive with those offered by other
corporations.

     Therefore, the Board of Directors has caused the Company to enter into this
Agreement, and the Company and Executive agree as follows:

1    DEFINITIONS

For purposes of this Agreement, the following terms have the following meanings.

1.1 "Affiliated Company" means an affiliated company as defined in Rule 12b-2 of
     ------------------
the Securities Exchange Act of 1934, as amended (the "Exchange Act").

1.2 "Base Salary" means Executive's annual base salary paid or payable
     -----------

the Company or an affiliated company immediately preceding the date of a Change
in Control.

     -----

1.4 "Cause" means Executive's:
     -----

     (i)  willful and continued failure to perform substantially Executive's
          duties with the Company or one of its affiliates as such duties are
          constituted as of a Change in Control after the Company delivers to
          Executive written demand for substantial performance specifically
          identifying the manner in which Executive has not substantially
          performed Executive's duties;

<PAGE>

     (ii) conviction for a felony; or

     (iii)willfully engaging in illegal conduct or gross misconduct which is
          materially and demonstrably injurious to the Company.

For purposes of this Section 1.4, no act or omission by Executive shall be
considered "willful" unless it is done or omitted in bad faith or without
reasonable belief that Executive's action or omission was in the best interests
of the Company. Any act or failure to act based upon (a) authority given
pursuant to a resolution duly adopted by the Board, (b) instructions of the
Chief Executive Officer or a senior officer of the Company, or (c) advice of
counsel for the Company shall be conclusively presumed to be done or omitted to
be done by Executive in good faith and in the best interests of the Company. For
purposes of subsections (i) and (iii) above, Executive shall not be deemed to be
terminated for Cause unless and until there shall have been delivered to
Executive a copy of a resolution duly adopted by the affirmative vote of not
less than three quarters of the entire membership of the Board at a meeting
called and held for such purpose (after reasonable notice is provided to
Executive and Executive is given an opportunity, together with counsel, to be
heard before the Board) finding that in the good faith opinion of the Board
Executive is guilty of the conduct described in subsection (i) or (iii) above
and specifying the particulars thereof in detail.

          13(d)(3) or 14(d)(2) of the Exchange Act) (a "Person"), other than
          those Persons in control of the Company as of the date hereof or a
          trustee or other fiduciary holding securities under an employee
          benefit plan of the Company or a corporation owned directly or
          indirectly by the stockholders of the Company in substantially the
          same proportions as their ownership of stock of the Company, become
          the beneficial owner (as defined in Rule 13d-3 under the Exchange
          Act), directly or indirectly, of securities of the Company
          representing 25% or more of the combined voting power of the Company's

          any individual becoming a director subsequent to the date hereof whose
          election or nomination for election by the Company's stockholders was
          approved by a vote of at least a majority of the directors then
          comprising the Incumbent

                                       2

<PAGE>

          Board shall be considered as though such individual were a member of
          the Incumbent Board; or

     (iii) The stockholders of the Company approve: (a) a plan of complete
          liquidation of the Company; (b) an agreement for the sale or
          disposition of all or substantially all of the Company's assets; (c) a
          merger, consolidation or reorganization of the Company with or
          involving any other corporation, other than a merger, consolidation or
          reorganization that would result in the voting securities of the
          Company outstanding immediately prior thereto continuing to represent
          (either by remaining outstanding or by being converted into voting
          securities of the surviving entity) at least 50% of the combined
          voting power of the voting securities of the Company (or such
          surviving entity) outstanding immediately after such merger,
          consolidation or reorganization.

However, in no event shall a Change in Control be deemed to have occurred for
purposes of this Agreement if Executive is included in a Person that consummates
the Change in Control. Executive shall not be deemed to be included in a Person
by reason of ownership of (i) less than 3% of the equity in the Person or (ii)
an equity interest in the Person which is otherwise not significant as
determined prior to the Change of Control by a majority of the non-employee
continuing directors of the Company.

          responsibilities as constituted immediately prior to a Change in
          Control;

     (ii) requiring Executive (a) to be based at any office or location in

          substantially greater extent than required immediately prior to a
          Change in Control;

     (iii) reducing Executive's Base Salary;

payments required under this Section 5) (a "Payment") would be subject to the
excise tax imposed by Section 4999 of the Code, or any interest or penalties are
incurred by Executive with respect to such excise tax (such excise tax, together
with any such interest and penalties, are hereinafter collectively referred to
as the "Excise Tax"), then Executive shall be entitled to receive an additional
payment (a "Gross-Up Payment") in an amount such that after payment by Executive
of all taxes (including any interest or penalties imposed with respect to such
taxes), including, without limitation, any income taxes (and any interest and
penalties imposed with respect thereto) and Excise Tax imposed upon the Gross-Up
Payment, Executive retains an amount of the Gross-Up Payment equal to the Excise
Tax imposed upon the Payments. Notwithstanding the foregoing provisions of this
Subsection 5(i), if it is determined that Executive is entitled to a Gross-Up
Payment, but that Executive, after taking into account the Payments and the
Gross-Up Payment, would not receive a net after-tax benefit of at least $50,000
(taking into account both income taxes and any Excise Tax) as compared to the
net after-tax proceeds to Executive resulting from an elimination of the
Gross-Up Payment and a reduction of the Payments, in the aggregate, to an amount
(the "Reduced Amount") such that the receipt of Payments would not give rise to
any Excise Tax, then no Gross-Up Payment shall be made to Executive and the
Payments, in the aggregate, shall be reduced to the Reduced Amount.

(ii) Subject to the provisions of Subsection 5(iii), all determinations required
to be made under this Section 5, including whether and when a Gross-Up Payment
is required and the amount of such Gross-Up Payment and the assumptions to be
utilized in arriving at such determination, shall be made by
PricewaterhouseCoopers or such other certified public accounting firm as may be
designated by Executive (the "Accounting Firm") which shall provide detailed
supporting calculations both to the Company and Executive within 15 business
days of the receipt of notice from Executive that there has been a Payment, or
such earlier time as is requested by the Company. If the Accounting Firm is
serving as accountant or auditor for the individual, entity or group effecting
the Change in

Control, Executive shall appoint another nationally recognized accounting firm
to make the determinations required hereunder (which accounting firm shall then
be referred to as the Accounting Firm hereunder). All fees and expenses of the
Accounting Firm shall be borne solely by the Company. Any Gross-Up Payment, as
determined pursuant to this Section 5, shall be paid by the Company to Executive
within five days of the receipt of the Accounting Firm's determination. Any
determination by the Accounting Firm shall be binding upon the Company and
Executive. As a result of the uncertainty in the application of Section 4999 of
the Code at the time of the initial determination by the Accounting Firm
hereunder, it is possible that Gross-Up Payments which will not have been made
by the Company should have been made ("Underpayment"), consistent with the
calculations required to be made hereunder. If the Company exhausts its remedies
pursuant to Subsection 5(iii) and Executive thereafter is required to make a
payment of any Excise Tax, the Accounting Firm shall determine the amount of the
Underpayment that has occurred and any such Underpayment shall be promptly paid
by the Company to or for the benefit of Executive.

(iii) Executive shall notify the Company in writing of any claim by the Internal
Revenue Service that, if successful, would require the payment by the Company of
the Gross-Up Payment. Such notification shall be given as soon as practicable
but no later than ten business days after Executive is informed in writing of
such claim and shall apprise the Company of the nature of such claim and the
date on which such claim is requested to be paid. Executive shall not pay such
claim prior to the expiration of the 30-day period following the date on which
it gives such notice to the Company (or such shorter period ending on the date
that any payment of taxes with respect to such claim is due). If the Company
notifies Executive in writing prior to the expiration of such period that it
desires to contest such claim, Executive shall:

     (a)  give the Company any information reasonable requested by the Company
          relating to such claim,

     (b)  take such action in connection with contesting such claim as the
          Company shall reasonably request in writing from time to time,
          including, without limitation, accepting legal representation with
          respect to such claim by an attorney reasonably selected by the
          Company,

     (c)  cooperate with the Company in good faith in order effectively to
          contest such claim, and

     (d)  permit the Company to participate in any proceedings relating to such
          claim;

                                       8

<PAGE>

provided, however, that the Company shall bear and pay directly all costs and
expenses (including additional interest and penalties) incurred in connection
with such contest and shall indemnify and hold Executive harmless, on an
after-tax basis, for any Excise Tax or income tax (including interest and
penalties with respect thereto) imposed as a result of such representation and
payment of costs and expenses. Without limitation on the foregoing provisions of
this Subsection 5(iii), the Company shall control all proceedings taken in
connection with such contest and, at its sole option, may pursue or forgo any
and all administrative appeals, proceedings, hearings and conferences with the
taxing authority in respect of such claim and may, at its sole option, either
direct Executive to pay the tax claimed and sue for a refund or to contest the
claim in any permissible manner, and Executive agrees to prosecute such contest
to a determination before any administrative tribunal, in a court of initial
jurisdiction and in one or more appellate courts, as the Company shall
determine; provided, however, that if the Company directs Executive to pay such
claim and sue for a refund, the Company shall advance the amount of such payment
to Executive, on an interest-free basis, and shall indemnify and hold Executive
harmless, on an after-tax basis, from any Excise Tax or income tax (including
interest or penalties with respect thereto) imposed with respect to such advance
or with respect to any imputed income with respect to such advance; and further
provided that any extension of the statute of limitations relating to payment of
taxes for the taxable year of Executive with respect to which such contested
amount is claimed to be due is limited solely to such contested amount.
Furthermore, the Company's control of the contest shall be limited to issues
with respect to which a Gross-Up Payment would be payable hereunder, and
Executive shall be entitled to settle or contest, as the case may be, any other
issue raised by the Internal Revenue Service or any other taxing authority.

(iv) If, after the receipt by Executive of an amount advanced by the Company
pursuant to Subsection 5(iii), Executive becomes entitled to receive any refund
with respect to such claim, Executive shall (subject to the Company's complying
with the requirements of Subsection 5(iii) promptly pay to the Company the
amount of such refund (together with any interest paid or credited thereon after
taxes applicable thereto). If after the receipt by Executive of an amount
advanced by the Company pursuant to Subsection 5(iii), a determination is made
that Executive shall not be entitled to any refund with respect to such claim
and the Company does not notify Executive in writing of its intent to contest
such denial of refund prior to the expiration of 30 days after such
determination, then such advance shall be forgiven and shall not be required to
be repaid and the amount of such advance shall offset, to the extent thereof,
the amount of Gross-Up Payment required to be paid.

5.2 Tax Withholding. The Company may withhold from any amounts payable under
    ---------------
this Agreement such federal, state, local or foreign taxes as shall be required
to be withheld pursuant to any applicable law or regulation.
