                        NAME, PURPOSE, AND EFFECTIVE DATE

         The  Raytheon  Excess  Savings  Plan  ("Plan")  is  hereby  established
effective January 1, 1999. The Plan is both an excess benefit plan as defined in
Section  3(36) of ERISA and a  nonqualified,  unfunded  plan designed to provide
supplemental  retirement  benefits  to a select  group of  management  or highly
compensated employees within the meaning of Section 201(2) of ERISA. The Plan is
a new  plan  that,  to  the  extent  applicable  (and  consistent  with  Section
4.1(a)(1)),  replaces and supercedes  the excess  savings plan benefit  provided
under the Raytheon  Excess  Benefit Plan II. In no event shall a Participant  be
entitled to duplicate  excess benefits with respect to his or her  participation
in the Savings Plan (and any plans merged into the Savings Plan).

Deferral  Election  in  accordance  with the  procedures  specified  by the Plan
Administrator  and shall have his or her  Compensation  reduced by the amount of
contributions  that would have been  required  under the Savings Plan to provide

                                    BENEFITS

         4.1      Excess Savings Plan Benefit.

         (a)  The  Excess  Savings  Plan  Benefit  shall  equal  the  sum of the

4.1.2 of the Raytheon  Excess  Benefit Plan II as of December 31, 1998,  if any,
including the earnings credited under the plan through such date; and

After-Tax  Contributions,  Matching  Contributions and ESOP  Contributions  that
would have been made on behalf of a Participant  under the Savings Plan for each
Plan Year but that were not made because of the limitations on contributions and
benefits  imposed by Section 415 of the Code,  the  limitation  on  compensation
imposed by Section  401(a)(17) of the Code and the exclusion of Deferred Bonuses
and Compensation from the definition of compensation under the Savings Plan; and

                  (3) an amount  equal to the gains and  losses  that would have
accrued on the amounts  credited to the  Participant's  Account  under  Sections
4.1(a)(1)  and (2) if such amounts had been invested in the  investment  options
that may be available from time to time under the Savings Plan and in accordance
with the Participant's  investment  directions to the Plan Administrator (or its
designee  in   accordance   with   procedures  to  be  prescribed  by  the  Plan
Administrator).

                                       4

         (b) The amount of the credit under Section 4.1(a)(2) for each Plan Year
shall, to the extent applicable,  be determined based on the deferral percentage
designated  in the  Participant's  Salary  Deferral  Election for each such Plan
Year. The gains and losses prescribed in Section 4.1(a)(3) shall be credited (or
debited) from the end of the month the contributions  would have been made under
the  Savings  Plan until the end of the month  preceding  the date the  benefits
represented  by such  credits are  actually  distributed  to or on behalf of the
Participant.

         (c) In no event shall a  Participant  be entitled to  duplicate  Excess
Savings  Plan  Benefits  under  this  Plan  with  respect  to the  same  item of
compensation.

         4.2 Vesting. Except as set forth in Sections 4.5 and 4.6, a Participant
shall have a nonforfeitable right to his or her Excess Savings Plan Benefit.

         4.3 Distribution  Election.  Each Participant shall designate in his or
her initial  Salary  Deferral  Election  the manner in which  benefits  shall be
payable from the options  available under Section 4.4. Such designation shall be
irrevocable and shall apply to all amounts payable under the Plan. Distributions
shall be made only as specifically provided for in the Plan.

         4.4      Distribution Options.

         (a)  Except  as  otherwise  provided  herein,  the  distribution  of  a
Participant's  benefits under the Plan shall commence in the January immediately
following  the  calendar  year in which the  Participant  has a  termination  of
employment with the Company and its  affiliates,  and shall be payable in one of
the following  forms, as selected at the time of a Participant's  initial Salary
Deferral Election:

                  (1) in a lump-sum payment;

                  (2) in annual installments over a period of five (5) years,
payable in January of each year; or

                  (3) in annual installments over a period of ten (10) years,
payable in January of each year.

         (b) A Participant who  participated in the Raytheon Excess Benefit Plan
II immediately before January 1, 1999, and who selected  distribution options in
his or her initial salary deferral election under such plan, may, in lieu of the
distribution  options  described above,  elect to have his or her Excess Savings
Plan  Benefit  payable at the time and in the form  selected  under the Raytheon
Excess  Benefit  Plan II. If a  Participant  does not  designate a  distribution
option at the time of his or her initial Salary Deferral  Election in accordance
with this Section 4.4, the  Participant's  Excess  Savings Plan Benefit shall be
payable  in annual  installments  over a period of five (5)  years,  payable  in
January  of each year,  commencing  in the  January  immediately  following  the
calendar year in which the  Participant has a termination of employment with the
Company and its affiliates.  Upon the death of a Participant prior to a complete
distribution of the balance to the credit of his or her benefits under the Plan,
the remaining benefits shall be payable to his or her designated  Beneficiary in
accordance with the distribution options selected by the Participant pursuant to
this Section 4.4.

                                       5

         4.5 Benefits  Unfunded.  The benefits  payable  under the Plan shall be
paid solely out of the general assets of the  participating  Company that is the
employer  of the  Participant  (or was the  most  recent  employer)  at the time
benefits first become payable and shall not be otherwise  specifically funded in
any manner.  For this purpose,  the Plan  Administrator  shall maintain separate
books and records for each  participating  Company and its respective  Employees
who are Participants.  Nothing herein contained shall preclude the creation of a
bookkeeping or other reserve for benefits payable hereunder.

         4.6 ERISA Unwind  Provision.  Notwithstanding  anything to the contrary
contained herein,  if a judicial or administrative  determination is made or the
Plan Administrator has reason to believe that an Employee does not qualify as an
Eligible  Executive,  if required  hereunder,  the Employee  shall cease to be a
Participant  under  this  Plan  and the  Plan  Administrator  shall  pay to such
Employee  all  benefits  due him or her  from  this  Plan,  if  any,  as soon as
administratively feasible.


                                    ARTICLE V
                                 ADMINISTRATION

         5.1 Plan  Administration.  The Plan shall be  administered  by the Plan
Administrator  in  accordance  with its terms and  purposes.  The  Participant's
distribution  elections under Sections 4.3 and 4.4 shall constitute  expressions
of  preferences  concerning the amount and manner of payment of the benefits due
to or on behalf of the  Participant  from the Plan. As such,  the  Participant's
distribution elections shall not in any manner require the Plan Administrator to
pay benefits in accordance with such preferences.  The Plan Administrator  shall
determine  the amount and manner of payment of the  benefits due to or on behalf
of each Participant from the Plan and shall cause them to be paid in cash by the
appropriate participating Company accordingly.

         5.2 Finality of Decisions. Except as otherwise provided in Section 5.3,
the Plan  Administrator  shall have full  discretionary  authority  to determine
eligibility  for benefits and to construe the terms of the Plan,  including  all
questions of fact and law. In addition,  the  decisions  made by and the actions
taken by the Plan Administrator in the administration of the Plan shall be final
and conclusive on all persons,  and the Plan Administrator  shall not be subject
to any liability whatsoever with respect to the administration of the Plan.

         5.3 Claims  Procedures.  Any  Participant  or Beneficiary of a deceased
Participant  (such  Participant  or  Beneficiary  being  referred  to below as a
"Claimant")  may  deliver  to the  Plan  Administrator  a  written  claim  for a
determination  with respect to the amounts  distributable  to such Claimant from
the Plan. Any such determination by the Administrator  shall be made pursuant to
the  following  procedures,  which shall be  conducted  in a manner  designed to
comply with Section 503 of ERISA:

         (a) Step 1. Claims for a benefit  should be filed by a Claimant as soon
as practicable after the Claimant knows or should know that a dispute has arisen
with  respect  to the  benefit,  but at  least  thirty  (30)  days  prior to the
Claimant's  actual  retirement  date or, if  applicable,  within sixty (60) days
after the death,  disability or  termination  of  employment of the  Participant
whose  benefit is at issue,  by mailing a copy of the claim to the  Benefits and
Services   Department,   Raytheon   Company,   141  Spring  Street,   Lexington,
Massachusetts 02421.

                                       6

         (b) Step 2. In the event that a claim is wholly or partially  denied by
the Plan  Administrator,  the Plan Administrator  shall, within ninety (90) days
following receipt of the claim, so advise the Claimant in writing setting forth:
the specific reason or reasons for the denial;  specific  reference to pertinent
Plan  provisions on which the denial is based;  a description  of any additional
material or  information  necessary  for the  Claimant to perfect the claim;  an
explanation  as to  why  such  material  or  information  is  necessary;  and an
explanation of the Plan's claim review procedures.

         (c) Step 3. Within sixty (60) days following receipt of the denial of a
claim for a benefit,  a Claimant desiring to have the denial appealed shall file
a request for review by an officer of Raytheon Company or a review committee, as
designated by Raytheon  Company,  by mailing a copy thereof to the address shown
in Section 5.3(a);  provided,  however,  that such officer or any member of such
review  committee,  as  applicable,  may not be the person who made the  initial
adverse benefit determination nor a subordinate of such person.

         (d) Step 4. Within thirty (30) days following  receipt of a request for
review,  the designated officer or review committee shall provide the Claimant a
further opportunity to present his or her position. At the designated officer or
review  committee's  discretion,  such  presentation  may be  through an oral or
written  presentation.  Prior  to  such  presentation,  the  Claimant  shall  be
permitted the opportunity to review pertinent documents and to submit issues and
comments in writing.  Within a reasonable  time  following  presentation  of the
Claimant's  position,  which  usually  should not exceed  thirty (30) days,  the
designated  officer or review  committee shall inform the Claimant in writing of
the decision on review  setting  forth the reasons for such  decision and citing
pertinent provisions in the Plan.

         6.1  Amendment  and  Termination.  While  Raytheon  Company  intends to
maintain the Plan in conjunction with the Savings Plan for as long as necessary,
Raytheon Company reserves the right to amend and/or fully or partially terminate
the Plan at any time for whatever reasons it may deem appropriate, provided that
no amendment or termination of the Plan shall affect any participating Company's
obligation to pay the benefits due to the Participants hereunder but only to the
extent of the value of such  benefits  which have  accrued up to the date of the
amendment or termination.


                                   ARTICLE VII
                                  MISCELLANEOUS

         7.1 No Enlargement of Employee  Rights.  Nothing  contained in the Plan
shall be  construed  as a contract  of  employment  between  any  Company and an
Employee or as a right of any Employee to be continued in the  employment of any
Company,  or as a  limitation  of the  right of any  Company  to  discharge  any
Employee at any time, with or without notice and with or without cause.

         7.2  Assignment.  The  benefits  payable  under  this  Plan  may not be
assigned, alienated, transferred, pledged or otherwise encumbered.
