Trust may be adopted by any corporation or other entity (hereinafter referred to
as an Adopting Employer). Such adoption shall be made by the Adopting Employer
taking the actions designated by the Administrator as appropriate to the proper
adoption and operation of the Plan and Trust. In the event of the adoption of
the Plan and Trust by an Adopting Employer, the Plan and Trust shall be
interpreted in a manner consistent with such adoption. The Adopting Employers
shall be listed in Exhibit A attached to this Plan.

     1.5 Withdrawal of Adopting Employer.

terminated, voluntarily or involuntarily, at any time, as provided in this
section.

         (b) An Adopting Employer shall withdraw from the Plan and Trust if the
Plan and Trust, with respect to that Adopting Employer, fail to qualify under
sections 401(a) and 501(a) of the Code (or, in the opinion of the Administrator,
they may fail to so qualify) and the continued sponsorship of that Adopting
Employer may jeopardize the status with respect to the Company or the remaining
Adopting Employers, of the Plan and Trust under sections 401(a) and 501(a) of
the Code. The Adopting Employer shall receive at least thirty (30) days prior
written notice of a withdrawal under this subsection, unless a shorter period is

to.

attributable to Employees of the withdrawn Adopting Employer, the amount thereof
to be determined by the Administrator and the Trustee. The segregated assets
shall be held, paid to another trust, distributed or otherwise disposed of as is
appropriate under the circumstances; provided, however, that any transfer shall
be for the exclusive benefit of Participants and their Beneficiaries. A
withdrawal of an Adopting Employer from the Plan is not necessarily a
termination under ARTICLE XIV. If the withdrawal is a termination, then the
provisions of ARTICLE XIV shall also be applicable.

     3.2  Procedure for Joining the Plan. Each Eligible Employee may join the
Plan by communicating with the Recordkeeper in accordance with the instructions
that will be made available to each Eligible Employee. An enrollment in the Plan

as an Elective Deferral in accordance with the requirements of section 4.1(a);
(ii) election of investment funds in accordance with ARTICLE V; (iii) one or

an Eligible Employee, the Participant will remain a Participant of the Plan with
respect to contributions previously made but shall no longer be eligible to have

becomes an Eligible Employee. In the event the Participant is subsequently
transferred to a position in which he or she again becomes an Eligible Employee,

                                       14

         (a) (1) Elective Deferrals: Subject to the limitations otherwise 
prescribed herein, a Participant may authorize an Adopting Employer to reduce
his or her Compensation on a pre-tax basis by an amount equal to any whole
percentage of Compensation that does not exceed twenty percent (20%) and to have

Period by which it is administratively feasible to make such
re-characterization.

         (3) The Elective Deferrals and Employee After-Tax Contributions made 
on behalf of each Participant shall not in the aggregate exceed twenty percent
(20%) of the Participant's Compensation for any Plan Year. Notwithstanding the
preceding sentence, a Participant who is participating in the contributory
portion of either the Raytheon Bargaining Retirement Plan or the Raytheon
Non-Bargaining Retirement Plan (Exhibit A to each plan) may not make Elective
Deferrals and Employee After-Tax Contributions that in the aggregate exceed
seventeen percent (17%) of his or her Compensation.

         (4) A Participant may change his or her Elective Deferral percentage 
to increase or decrease said percentage by notifying the Recordkeeper, such
change to take effect as of the first Pay Period by which it is administratively
feasible to make such change.

         (5) A Participant may not make Elective Deferrals with respect to
Compensation that has already been made available to the Participant.

             (b)(1) Employee After-Tax Contributions: Subject to the
limitations otherwise prescribed herein, a Participant may authorize an Adopting
Employer to reduce his or her Compensation on an after-tax basis by an amount
equal to any whole percentage of Compensation that does not exceed twenty
percent (20%) and to have such amount contributed to the Plan as an Employee
After-Tax Contribution. Notwithstanding the preceding sentence, a Participant

Bargaining Retirement Plan or the Raytheon Non-Bargaining Retirement Plan
(Exhibit A to each plan) may not make Employee After-Tax Contributions that
exceed seventeen percent (17%) of his or her Compensation.

                (3) A Participant may change his or her Employee After-Tax 
Contribution percentage to increase or decrease said percentage by notifying the
Recordkeeper, such change to take effect as of the first Pay Period by which it
is administratively feasible to make such change.

         (c) Qualified Nonelective Contributions: Each Plan Year the Adopting
Employers may contribute to the Trust such amounts as determined by the Senior
Vice President of Human Resources of the Company or other officer to whom
authority to determine contributions is delegated by the Board of Directors, in
his or her sole discretion. Any amounts contributed under this subsection are to
be designated by the Adopting Employers as Qualified Nonelective Contributions.

     4.2 Stock Bonus Portion of the Plan.

         (a) Matching Contributions: Subject to the limitations otherwise 
prescribed herein, each Adopting Employer shall make Matching Contributions
equal in value to one hundred percent (100%) of the total Elective Deferrals and
Employee After-Tax Contributions made for each Pay Period by each Participant
who is an Eligible Employee of such Adopting Employer, but the total of such
Matching Contributions for any Participant shall not exceed four percent (4%) of
a Participant's Compensation from such Adopting Employer for each such Pay
Period.

         (b) The  Matching Contribution shall be made in either Common Stock or
cash that is invested in Common Stock. The number of shares of Common Stock
contributed by the Adopting Employer or acquired with Matching Contributions
under this subsection (b) shall be allocated to the Participant's Account by the
Trustee and such allocation shall equal the number of shares of Common Stock
which the Trustee could have purchased for the Participant at the Current Market
Value. Such Matching Contribution shall remain invested in Common Stock in
accordance with section 5.1(b).

         (c) Special Matching Contribution for Allied-Signal Participants:
Subject to the limitations otherwise prescribed herein, each Adopting Employer
shall make special Matching Contributions with respect to the Elective Deferrals
and Employee After-Tax Contributions made by Allied-Signal Participants during
the period commencing September 11, 1998 and ending September 10, 1999 (the
"Transition Period"). The special Matching Contributions required under this
subsection (c) shall equal the amount of matching contributions the
Allied-Signal Participants would have received under the AlliedSignal Savings
Plan and the AlliedSignal Thrift Plan (collectively, the "AlliedSignal plans")
if they had continued to participate in the AlliedSignal plans during the
Transition Period, reduced by the amount of Matching Contributions that the
AlliedSignal Participants are entitled to under this Plan with respect to the
<PAGE>
 
                                       16

Elective Deferrals and Employee After-Tax Contributions made during the
Transition Period. The special Matching Contributions under this subsection (c)
shall be made on or after September 11, 1999, shall be considered Matching
Contributions for the 1999 Plan Year, and shall be treated as Matching
Contributions for all other purposes of the Plan. For purposes of this
subsection (c), an "AlliedSignal Participant" shall mean a Participant who
immediately prior to September 10, 1998 was an employee of AlliedSignal and who
on such date became an Employee of the Company or one of its Affiliates in
connection with the Company's acquisition of AlliedSignal's defense
communications business, provided such Employee (1) does not voluntarily
terminate employment with the Company and all of its Affiliates prior to
September 11, 1999; (2) is not terminated from employment with the Company and
all of its Affiliates for cause prior to September 11, 1999; (3) is not an

         (a) ESOP Contributions: For each Plan Year, the Adopting Employers
shall make an ESOP Contribution equal to one-half of one percent (0.5%) of the
Participants' Compensation for such Plan Year. The ESOP Contribution may be made
in cash, Common Stock or a combination thereof at the discretion of the Adopting
Employers. Within a reasonable period of time before the allocation to
individual accounts as specified in subsection (b), the Trustee shall use the
ESOP Contribution, to the extent not contributed in Common Stock, to acquire
Common Stock which will be held by the Trustee for the benefit of the
Participants in the Plan.

         (b) Allocation of ESOP Contribution: As soon as administratively 
feasible after the ESOP Contribution is made to the Plan, the Administrator
shall allocate the ESOP Contribution to the Participants who received
Compensation during such Plan Year. The ESOP Contribution (consisting of Common
Stock and any residual cash) shall be allocated to those eligible Participants
in the same ratio as each such Participant's Compensation for the Plan Year
bears to the Total Compensation of all such eligible Participants for the Plan
Year.

     4.4 Rollover Contributions.

         (a) Participants may transfer into the Plan Qualifying Rollover Amounts
from other qualified plans or Conduit IRAs, subject to the following terms and
conditions:

            (1) the  transferred funds are received by the Trustee no later than
sixty (60) days from receipt by the Participant of a distribution from another
qualified plan or, in the event that the funds are transferred from a Conduit
IRA, no later than sixty (60) days from the date that the Participant
receives such funds from the individual retirement account;

            (2) the Rollover Contributions transferred pursuant to this section 
4.4 (a) shall be credited to the Participant's Rollover Contribution Account and
will be invested upon receipt by the Trustee; and
<PAGE>
 
                                       17


            (3) a Rollover Contribution will not be accepted unless (A) the 
Employee on whose behalf the Rollover Contribution will be made is either a
Participant or an Eligible Employee who has notified the Administrator that he
or she intends to become a Participant as of the first date on which he or she
is eligible therefor, and (B) all required information, including selection of
specific investment accounts, is provided to the Recordkeeper.

         (b) For purposes of this section, the following terms shall have the
meanings specified:

             (1) Qualifying Rollover Amounts. Amounts that can be transferred to
the Plan under either section 402(c), 403(a)(4) or 408(d)(3)(A)(ii) of the Code.

section 408(d)(3)(A)(ii) of the Code.

          (a) The Plan shall accept a transfer of assets, including elective 
transfers in accordance with Treas. Regs. section 1.411(d)-4 Q&A-3(b) and
transfers in connection with a plan merger, directly from another plan qualified
under section 401(a) of the Code only if the Administrator, in its sole
discretion, agrees to accept such a transfer. In determining whether to accept
such a transfer, the Administrator shall consider the administrative
inconvenience engendered by such a transfer and any risks to the continued
qualification of the Plan under section 401(a) of the Code. Acceptance of any
such transfer shall not preclude the Administrator from refusing any such
subsequent transfers.

         (b) Any transfer of assets accepted under this subsection shall be 
separately accounted for at all times and shall remain subject to the
provisions of the transferor plan (as it existed at the time of such transfer)
to the extent required by section 411(d)(6) of the Code (including, but not
limited to, any rights to qualified joint and survivor annuities and qualified
preretirement survivor annuities) as if such provisions were part of the Plan.
In all other respects, however, such transferred assets will be subject to the
provisions of this Plan. The Administrator may, but is not required to, describe
in Exhibit B to this Plan the special provisions that must be preserved under
section 411(d)(6) of the Code, if any, following the transfer of assets from
another plan in accordance with this subsection (b).

         (c) Assets accepted under this section shall be nonforfeitable. 
Notwithstanding the preceding sentence, assets transferred in connection with
the plan mergers identified in section 1.1(b) shall vest in accordance with the
provisions of ARTICLE VI.

     4.6  Refund of Contributions to the Adopting Employers.

Notwithstanding the provisions of ARTICLE XII, if, or to the extent that, any
Adopting Employer's deductions for contributions made to the Plan are
disallowed, such Adopting Employer will have the right to obtain the return of
any such contributions for a period of one (1) year from the date of
disallowance. For this purpose, all contributions are made, other than Employee
After-Tax Contributions, subject to the condition that they are deductible under
the Code for the taxable year of the Adopting Employers for which the
contributions are made. Furthermore, any contribution made on the basis of a
mistake in fact may be returned to the Adopting Employers within one (1) year
from the date such contribution was made.

         4.7  Payment. The Adopting Employers shall pay to the Trustee in
U.S. currency, or by other property acceptable to the Trustee, all contributions
for each Plan Year within the time prescribed by law, including extensions
granted by the Internal Revenue Service, for filing the federal income tax
return of the Company for its taxable year in which such Plan Year ends. Unless
designated by the Adopting Employers as nondeductible, all contributions made,
other than Employee After-Tax Contributions, shall be deemed to be conditioned
on their current deductibility under section 404 of the Code.

          (a) Elective Deferrals, Employee After-Tax Contributions, Matching
Contributions and Qualified Nonelective Contributions allocable to the Accounts
of Highly Compensated Employees shall not in any Plan Year exceed the limits

applicable limits) are not exceeded, regardless of whether such adjustments
affect some Participants more than others. This section shall be administered
and interpreted in accordance with sections 401(k) and 401(m) of the Code.

          (b)(1) The Actual Deferral Percentage of the Highly Compensated
Employees shall not exceed, in any Plan Year, the greater of:

                 (A) one hundred twenty-five percent (125%) of the Actual
Deferral Percentage for all other Eligible Participants; or

                 (B) the lesser of two hundred percent (200%) of the Actual 
Deferral Percentage for all other Eligible Participants or the Actual Deferral 
Percentage for the other Eligible Participants plus two (2) percentage points.

             (2) The Actual Contribution Percentage of the Highly Compensated
Employees shall not exceed, in any Plan Year, the greater of:

                 (A) one hundred twenty five percent (125%) of the Actual 
Contribution Percentage for all other Eligible Participants; or

                 (B) the lesser of two hundred percent (200%) of the Actual 
Contribution Percentage for all other Eligible Participants or the Actual
Contribution Percentage for the other Eligible Participants plus two (2) 
percentage points.

             (3) The sum of the Actual Deferral Percentage and the Actual 
Contribution Percentage for the Highly Compensated Employees shall not exceed, 
in any Plan Year, the sum of:

                  (A) one hundred twenty-five percent (125%) of the greater of:

                      (i) the Actual Deferral Percentage of the other Eligible
Participants; or

                     (ii) the Actual Contribution Percentage of the other 
Eligible Participants; and

                  (B) two plus the lesser of:

                      (i) the amount in paragraph (3)(A)(i); or

                     (ii) the amount in paragraph (3)(A)(ii); provided that the
amount in this paragraph (3)(B) shall not exceed two hundred percent (200%) of 
the lesser of the amount in paragraph (3)(A)(i) or the amount in paragraph
(3)(A)(ii).

             (4) The limitations under section 4.8(b)(3) shall be modified to 
reflect any higher limitations provided by the Internal Revenue Service under 
regulations, notices or other official statements.

                 (c) The following terms shall have the meanings specified:

                     (1) Actual Contribution Percentage.  The average of the 
ratios for a designated group of Employees (calculated separately for each
Employee in the group) of the sum of the Matching Contributions (other than
those treated as part of the Actual Deferral Percentage), Qualified Nonelective
Contributions (other than those treated as part of the Actual Deferral
Percentage), Employee After-Tax Contributions and Elective Deferrals (other than
those treated as part of the Actual Deferral Percentage) allocated for the
applicable year on behalf of the Participant, divided by the Participant's
Compensation for such applicable year. The "applicable year" for determining the
Actual Contribution Percentage for the group of Highly Compensated Employees
shall be the current Plan Year. For all other Eligible Participants, the
"applicable year" for determining the Actual Contribution Percentage shall be
the current Plan Year, unless, in accordance with the procedures prescribed by
the Internal Revenue Service, the Administrator elects to use the immediately
preceding Plan Year. In the event the Administrator elects to use the
immediately preceding Plan Year for this purpose for any Plan Year, the
Administrator shall so indicate in Exhibit C to this Plan.

                     (2) Actual Deferral Percentage. The average of the ratios 
for a designated group of Employees (calculated separately for each Employee in
the group) of the sum of the Elective Deferrals, Qualified Nonelective

year on behalf of a Participant, divided by the Participant's Compensation for
<PAGE>
 
                                       20

such applicable year. The "applicable year" for determining the Actual Deferral
Percentage for the group of Highly Compensated Employees shall be the current
Plan Year. For all other Eligible Participants, the "applicable year" for
determining the Actual Deferral Percentage shall be the current Plan Year,
unless in accordance with the procedures prescribed by the Internal Revenue
Service, the Administrator elects to use the immediately preceding Plan Year. In
the event the Administrator elects to use the immediately preceding Plan Year
for this purpose for any Plan Year, the Administrator shall so indicate in
Exhibit C to this Plan.

                     (3) Compensation.  To the extent regulations permit the 
definition of Compensation in ARTICLE II to be used, then such definition shall
be applied for purposes of this ARTICLE; provided, however, that to the extent
such definition is not so permitted, then Compensation shall include all
compensation required to be counted under section 414(s) of the Code; provided
further, however, that this definition shall not apply for purposes of the
definition of Highly Compensated Employee in section 2.29.

                     (4) Eligible  Participant. Any Employee of the Company who
is authorized under the terms of the Plan to make Elective Deferrals, Employee
After-Tax Contributions or have Qualified Nonelective Contributions allocated to
his or her Account for the Plan Year.

                 (d) For purposes of determining whether a plan satisfies the
Actual Contribution Percentage test of section 401(m), all Employee and matching
contributions that are made under two (2) or more plans that are aggregated for
purposes of section 401(a)(4) and 410(b) (other than section 410(b)(2)(A)(ii))
are to be treated as made under a single plan and that if two (2) or more plans
are permissively aggregated for purposes of section 401(m), the aggregated plans
must also satisfy section 401(a)(4) and 410(b) as though they were a single
plan.

                  (e) In calculating the Actual Contribution Percentage for
purposes of section 401(m), the actual contribution ratio of a Highly
Compensated Employee will be determined by treating all plans subject to section
401(m) under which the Highly Compensated Employee is eligible (other than those
that may not be permissively aggregated) as a single plan.

                  (f) For purposes of determining whether a plan satisfies the
Actual Deferral Percentage test of section 401(k), all elective contributions
that are made under two (2) or more plans that are aggregated for purposes of
section 401(a)(4) or 410(b) (other than section 410(b)(2)(A)(ii)) are to be
treated as made under a single plan and that if two (2) or more plans are
permissively aggregated for purposes of section 401(k), the aggregated plans
must also satisfy sections 401(a)(4) and 410(b) as though they were a single
plan.

                  (g) In calculating the Actual Deferral Percentage for purposes
of section 401(k), the actual deferral ratio of a Highly Compensated Employee
will be determined by treating all cash or deferred arrangements under which the
Highly Compensated Employee is eligible (other than those that may not be
permissively aggregated) as a single arrangement.

                                       21

                  (h) An elective contribution will be taken into account under
the Actual Deferral Percentage test of section 401(k)(3)(A) of the Code for a
Plan Year only if it is allocated to the Employee as of a date within that Plan
Year. For this purpose, an elective contribution is considered allocated as of a
date within a Plan Year if the allocation is not contingent on participation or
performance of services after such date and the elective contribution is
actually paid to the Trust no later than twelve (12) months after the Plan Year
to which the contribution relates.

         4.9  Correction of Excess Contributions.

                  (a) Excess Contributions shall be corrected as provided in
this section. The Administrator may also prevent anticipated Excess
Contributions as provided in this section. The Administrator may use any method
of correction or prevention provided in this section or any combination thereof,
as it determines in its sole discretion. This section shall be administered and
interpreted in accordance with sections 401(k) and 401(m) of the Code.

                  (b) The Administrator may refuse to accept any or all
prospective Elective Deferrals to be contributed by a Participant.

                  (c)(1) The Company may, in its sole discretion, elect to
contribute, as provided in section 4.1(c), a Qualified Nonelective Contribution
in an amount necessary to satisfy any or all of the requirements of section 4.8.

                     (2) Qualified Nonelective Contributions for a Plan Year 
shall only be allocated to the Accounts of Participants who are not Highly
Compensated Employees. Qualified Nonelective Contributions shall be allocated
first to the Participant with the lowest Compensation for that Plan Year and any
remaining Qualified Nonelective Contributions thereafter shall be allocated to
the Participant with the next lowest Compensation for that Plan Year. This
allocation method shall continue in ascending order of Compensation until all
such Qualified Nonelective Contributions are allocated. The allocation to any
Participant shall not exceed the limits under section 415 of the Code. If two or
more Participants have identical Compensation, the allocations to them shall be
proportional.

                     (3) Qualified Nonelective Contributions for a Plan Year
shall be contributed to the Trust within twelve (12) months after the close of
such Plan Year.

                     (4) Qualified Nonelective Contributions shall only be 
allocated to Participants who receive Compensation during the Plan Year for
which such contribution is made.

                 (d) The Administrator may, during a Plan Year, distribute to a
Participant (or such Participant's Beneficiary if the Participant is deceased),
any or all Excess Contributions or Excess Deferrals (whether Elective Deferrals,
Matching Contributions or Qualified Nonelective Contributions) allocable to that
Participant's Account for that Plan Year, notwithstanding any contrary provision
of the Plan. Such distribution may include earnings or losses (if any)
attributable to such amounts, as determined by the Administrator.

                                       22

                  (e)(1) The Administrator may recharacterize any or all Excess
Contributions for a Plan Year as Employee contributions in accordance with the
provisions of this subsection. Any Excess Contributions that are so
recharacterized shall be treated as if the Participant had elected to instead
receive cash Compensation on the earliest date that any Elective Deferrals made
on behalf of the Participant during the Plan Year would have been received had
the Participant originally elected to receive such amount in cash and then
contributed such amount as an Employee contribution. To the extent required by
the Internal Revenue Service, however, such recharacterized Excess Contributions
shall continue to be treated as if such amounts were not recharacterized.

                     (2) The Administrator shall report any recharacterized 
Excess Contributions as Employee contributions to the Internal Revenue Service
and to the affected Participants at such times and in accordance with such
procedures as are required by the Internal Revenue Service. The Administrator
shall take such other actions regarding the amounts so recharacterized as may be
required by the Internal Revenue Service.

                     (3) Excess Contributions may not be recharacterized under
this subsection more than two and one-half (2 1/2) months after the close of the
Plan Year to which the recharacterization relates. Recharacterization is deemed
to occur when the Participant is so notified (as required by the Internal
Revenue Service).
                     (4) The amount of Excess Contributions to be distributed 
or recharacterized shall be reduced by Excess Deferrals previously distributed
for the taxable year ending in the same Plan Year and Excess Deferrals to be
distributed for a taxable year will be reduced by Excess Contributions
previously distributed or recharacterized for the Plan beginning in such taxable
year.

                 (f)(1) The Administrator may distribute any or all Excess
Contributions for a Plan Year in accordance with the provisions of this
subsection. Such distribution may only occur after the close of such Plan Year
and within twelve (12) months of the close of such Plan Year. In the event of
the termination of the Plan, such distribution shall be made within twelve (12)
months after such termination. Such distribution shall include the income
allocable to the amounts so distributed, as determined under this subsection.
The Administrator may make any special allocations of earnings or losses
necessary to carry out the provisions of this subsection. A distribution of an
Excess Contribution under this subsection may be made without regard to any
notice or consent otherwise required pursuant to sections 411(a)(11) and 417 of
the Code.

                     (2)(A) The income allocable to Excess Contributions
distributed under this subsection shall equal the allocable gain or loss for the
Plan Year. Income includes all earnings and appreciation, including such items
as interest, dividends, rent, royalties, gains from the sale of property,
appreciation in the value of stock, bonds, annuity and life insurance contracts,
and other property, without regard to whether such appreciation has been
realized.

                                       23

                        (B) The allocable gain or loss for the Plan Year may be
determined under any reasonable method consistently applied by the
Administrator. Alternatively, the Administrator may, in its discretion,
determine such allocable gain or loss for the Plan Year under the method set
forth in subparagraph (C).

                        (C) Under this method, the allocable gain or loss for 
the Plan Year is determined by multiplying the income for the Plan Year
allocable to Elective Deferrals (and amounts treated as Elective Deferrals) by a
fraction, the numerator of which is the Excess Contributions by the Participant
for the Plan Year and the denominator of which is the total Account balance of
the Participant attributable to Elective Deferrals (and amounts treated as
Elective Deferrals) as of the beginning of the Plan Year, increased by any
Elective Deferrals (and amounts treated as Elective Deferrals) by the
Participant for the Plan Year.

                     (3) Amounts distributed under this subsection (or other 
provisions of this section) shall first be treated as distributions from the
Participant's subaccounts in the following order:

                        (A) from the Participant's Elective Deferrals Account
(if such Excess Contribution is attributable to Elective Deferrals);

                        (B) from the Participant's Qualified Nonelective
Contribution Account (if such Excess Contribution is attributable to Qualified
Nonelective Contributions); and

                        (C) from the Participant's Matching Contribution 
Account (if such Excess Contribution is attributable to Matching Contributions).

                 (g)(1) The term "Excess Contribution" shall mean, with
respect to a Plan Year, the excess of the Elective Deferrals (including any
Qualified Nonelective Contributions and Matching Contributions that are treated
as Elective Deferrals under sections 401(k)(2) and 401(k)(3) of the Code) on
behalf of eligible Highly Compensated Employees for the Plan Year over the
maximum amount of such contributions permitted under sections 401(k)(2) and
401(k)(3) of the Code.

                    (2) Any distribution of Excess Contributions for a Plan Year
shall be made to Highly Compensated Employees on the basis of the amount of
contributions by, or on behalf of, each such Highly Compensated Employee.

                    (3) The amount of Excess Contributions to be distributed or
recharacterized shall be reduced by Excess Deferrals previously distributed for
the taxable year ending in the same Plan Year and Excess Deferrals to be
distributed for a taxable year will be reduced by Excess Contributions
previously distributed or recharacterized for the Plan beginning in such taxable
year.

     4.10 Correction of Excess Deferrals.

          (a) Excess Deferrals shall be corrected as provided in this section. 
The Administrator may also prevent anticipated Excess Deferrals as provided in
this section. The Administrator may use any method of correction or prevention
provided in this section or any combination thereof, as it determines in its
sole discretion. A distribution of an Excess Deferral under this section may be
made without regard to any notice or consent otherwise required pursuant to
sections 411(a)(11) and 417 of the Code. This section shall be administered and
interpreted in accordance with sections 401(k) and 402(g) of the Code.

          (b) The Administrator may refuse to accept any or all prospective 
Elective Deferrals to be contributed by a Participant.

          (c)(1) The Administrator may distribute any or all Excess Deferrals 
to the Participant on whose behalf such Excess Deferrals were made before the
close of the Applicable Taxable Year. Distributions under this subsection
include income allocable to the Excess Distribution so distributed, as
determined under this subsection.

             (2) Distribution under this subsection shall only be made if all 
the following conditions are satisfied:

                 (A) the Participant seeking the distribution designates the
distribution as an Excess Deferral;

                 (B) the distribution is made after the date the Excess Deferral
is received by the Plan; and

                 (C) the Plan designates the distribution as a distribution of 
an Excess Deferral.

             (3) The income allocable to the Excess Deferral distributed under
this subsection shall be determined in the same manner as under subsection
(d)(3), except that income shall only be determined for the period from the
beginning of the Applicable Taxable Year to the date on which the distribution
is made.

          (d)(1) The Administrator may distribute any or all Excess Deferrals
to the Participant on whose behalf such Excess Deferrals were made after the
close of the Applicable Taxable Year. Distribution under this subsection shall
only be made if the Participant timely provides the notice required under
subsection (d)(2) and such distribution is made after the Applicable Taxable
Year and before the first April 15 following the close of the Applicable Taxable
Year. Distributions under this subsection shall include income allocable to the
Excess Deferrals so distributed, as determined under this subsection.
<PAGE>
 
                                       25

             (2) Any  Participant seeking a distribution of an Excess Deferral 
in accordance with this subsection must notify the Administrator of such request
no later than the first March 15 following the close of the Applicable Taxable
Year. The Administrator may agree to accept notification received after such
date (but before the first April 15 following the close of the Applicable
Taxable Year) if it determines that it would still be administratively
practicable to make such distribution in view of the delayed notification. The
notification required by this subsection shall be deemed made if a Participant's
Elective Deferrals to the Plan in any Plan Year create an Excess Deferral.

             (3) The income allocable to the Excess Deferral distributed under
this subsection shall be determined in the same manner as under section
4.9(f)(2), except that the term "Excess Deferrals" shall be substituted for
"Excess Contributions" and the term "Applicable Taxable Year" shall be
substituted for "Plan Year." The Administrator may make any special allocations
of earnings or losses necessary to carry out the provisions of this subsection.

          (e) The following terms shall have the meanings specified:

              (1) Applicable Taxable Year. The taxable year (for federal income
tax purposes) of the Participant in which an Excess Deferral must be included in
gross income (when made) in accordance with section 402(g) of the Code.

              (2) Excess Deferral. A Participant's Elective Deferrals (and other
contributions limited by section 402(g) of the Code), for an Applicable Taxable
Year that are in excess of the limits imposed by section 402(g) of the Code for
such Applicable Taxable Year.

     4.11 Correction of Excess Aggregate Contributions.

          (a) Excess Aggregate Contributions shall be corrected as provided in
this section. The Administrator may use any method of correction or
prevention provided in this section or any combination thereof, as it determines
in its sole discretion. This section shall be administered and interpreted in
accordance with sections 401(k) and 401(m) of the Code.

          (b) The Administrator may refuse to accept any or all prospective 
Elective Deferrals to be contributed to a Participant.

          (c)(1) The Company may, in its sole discretion, elect to contribute, 
as provided in section 4.1(c), a Qualified Nonelective Contribution in an
amount necessary to satisfy any or all of the requirements of section 4.8.

             (2) Qualified Nonelective Contributions for a Plan Year shall only
be allocated to the Accounts of Participants who are not Highly Compensated
Employees. Qualified Nonelective Contributions shall be allocated first to the
Participant with the lowest Compensation for that Plan Year and any remaining
Qualified Nonelective Contributions thereafter shall be allocated to the
Participant with the next lowest compensation for that Plan Year. This
allocation method shall continue in ascending order of Compensation until all
such Qualified Nonelective Contributions are allocated. The allocation to any
Participant shall not exceed the limits under section 415 of the Code. If two or
more Participants have identical Compensation, the allocations to them shall be
proportional.
<PAGE>
 
                                       26

             (3) Qualified Nonelective Contributions for a Plan Year shall be
contributed to the Trust within twelve (12) months after the close of such 
Plan Year.

             (4) Qualified Nonelective Contributions shall only be allocated to
Participants who receive Compensation during the Plan Year for which such 
contribution is made.

          (d) The Administrator may, during a Plan Year, distribute to a
Participant (or such Participant's Beneficiary if the Participant is deceased),
any or all Excess Aggregate Contributions allocable to that Participant's
Account for that Plan Year, notwithstanding any contrary provision of the Plan.
Such distribution may include earnings or losses (if any) attributable to such
amounts, as determined by the Administrator.

          (e)(1) The Administrator may forfeit any or all Excess Aggregate 
Contributions for a Plan Year in accordance with the provisions of this
subsection. The amounts so forfeited shall not include any amounts that are
nonforfeitable under ARTICLE VI.

              (2) Any forfeitures under this subsection shall be made in 
accordance with the procedures for distributions under subsection (f) except
that such amounts shall be forfeited instead of being distributed.

          (f)(1) The Administrator may distribute any or all Excess Aggregate 
Contributions for a Plan Year in accordance with the provisions of this
subsection. Such distribution may only occur after the close of such Plan Year
and within twelve (12) months of the close of such Plan Year. Such distributions
shall be specifically designated by the Administrator as a distribution of
Excess Aggregate Contributions. In the event of the complete termination of the
Plan, such distribution shall be made within twelve (12) months after such
termination. Such distribution shall include the income allocable to the amounts
so distributed, as determined under this subsection. The Administrator may make
any special allocations of earnings or losses necessary to carry out the
provisions of this subsection. A distribution of an Excess Aggregate
Contribution under this subsection may be made without regard to any notice or
consent otherwise required pursuant to sections 411(a)(11) and 417 of the Code.

              (2)(A) The income allocable to Excess Aggregate Contributions
distributed under this subsection shall equal the allocable gain or loss for the
Plan Year. Income includes all earnings and appreciation, including such items
as interest, dividends, rent, royalties, gains from the sale of property,
appreciation in the value of stock, bonds, annuity and life insurance contracts,
and other property, without regard to whether such appreciation has been
realized.

                 (B) The allocable gain or loss for the Plan Year may be 
determined under any reasonable method consistently applied by the
Administrator. Alternatively, the Administrator may, in its discretion,
determine such allocable gain or loss for the Plan Year under the method set
forth in subparagraph (C).
<PAGE>
 
                                       27

                 (C) Under this method, the allocable gain or loss for the Plan
Year is determined by multiplying the income for the Plan Year allocable to
employee contributions, matching contributions and amounts treated as matching
contributions by a fraction, the numerator of which is the Excess Aggregate
Contributions for the Participant for the Plan Year and the denominator of which
is the total Account balance of the Participant attributable to employee
contributions, matching contributions and amounts treated as matching
contributions as of the beginning of the Plan Year, increased by the employee
contributions, matching contributions and amounts treated as matching
contributions for the Participant for the Plan Year.

              (3) Amounts distributed under this subsection (or other provisions
of this section) shall first be treated as distributions from the Participant's
subaccounts in the following order:

                 (A) from the Participant's Employee After-Tax Contribution 
Account (if such Excess Aggregate Contribution is attributable to Employee
After-Tax Contributions);

                 (B) from the Participant's Qualified Nonelective Contribution
Account (if such Excess Aggregate Contribution is attributable to Qualified
Nonelective Contributions); and

                 (C) from the Participant's Matching Contribution Account (if 
such Excess Aggregate Contribution is attributable to Matching Contributions).

          (g)(1) The term "Excess Aggregate Contribution" shall mean, with
respect to a Plan Year, the excess of the aggregate amount of the matching
contributions and employee contributions (including any Qualified Nonelective
Contributions or elective deferrals taken into account in computing the Actual
Contribution Percentage) actually made on behalf of eligible Highly Compensated
Employees for the Plan Year over the maximum amount of such contributions
permitted under section 401(m)(2)(A) of the Code.

             (2) The terms "employee contributions" and "matching contributions"
shall, for purposes of this section, have the meanings set forth in Treas. Reg.
ss.1.401(m)-1(f).

             (3) Any distribution of Excess Aggregate Contributions for a Plan 
Year shall be made to Highly Compensated Employees on the basis of the amount of
contributions by, or on behalf of, each such Highly Compensated Employee.

         4.12 Correction of Multiple Use.

              (a) If the limitations of Treas. Reg. ss.1.401(m)-2 are exceeded 
for any Plan Year, then correction shall be made in accordance with the
provisions of this section. This section shall be administered and interpreted
in accordance with sections 401(k) and 401(m) of the Code.
<PAGE>
 
                                       28

               (b) Any correction required by this section shall be calculated 
and administered in accordance with the provisions for correcting Excess
Contributions (in section 4.9), Excess Aggregate Contributions (in section 4.11)
or both, as the Administrator determines in its sole discretion. Any correction
required by this section, to the extent possible, shall be made only with
respect to those Highly Compensated Employees who are eligible in both the
arrangement subject to section 401(k) of the Code and the Plan, as subject to
section 401(m) of the Code.

                                    ARTICLE V

                             Investment of Accounts

     5.1  Election of Investment Funds.

          (a) Except as otherwise prescribed in subsections (b), (c) and (d)
below, upon enrollment in the Plan, each Participant shall direct that the funds
in the Participant's Account be invested in increments of one percent (1%) in
one or more of the investment options designated by the Administrator, which may
include designated investment funds, specific investments or both. The
investment choices made available shall be sufficient to allow compliance with
section 404(c) of ERISA.

(         (b) Matching Contributions made with respect to Plan Years beginning 
on and after January 1, 1999 must be invested in Common Stock until the
beginning of the fifth (5th) Plan Year following the Plan Year for which such
contributions are made. Thereafter, a Participant may designate the investment
of the Matching Contribution funds in accordance with the provisions of
subsection (a) above. Notwithstanding anything herein to the contrary, the
five-year restriction prescribed in this subsection (b) shall no longer apply
immediately following a Participant's Severance from Service or on or after
January 1 of the calendar year in which a Participant attains age 55.

           (c) Except as otherwise determined by the Administrator, amounts held
in a Participant's ESOP Contribution Account shall be invested in Common Stock.
Notwithstanding the preceding sentence, any Participant who has attained age 55
and completed a Period of Participation of at least ten (10) years shall be
permitted to direct that up to twenty-five percent (25%) of the total number of
shares of Common Stock (rounded to the nearest whole integer) allocated to the
Participant's ESOP Contribution Account as of the December 31 immediately
preceding each Plan Year during the Qualified Election Period may be invested
among the otherwise available investment options under the Plan in accordance
with the provisions of subsection (a) above. With respect to a qualified
Participant's final diversification election, fifty percent (50%) is substituted
for twenty-five percent (25%) in determining the amount subject to the
diversification election. Any direction to diversify hereunder may be made
within 90 days after the close of each Plan Year during the Participant's
Qualified Election Period, as defined below. Any direction made during the
applicable 90-day period following any Plan Year may be revoked or modified at
any time during such 90-day period. The diversification of the ESOP Contribution
Account as provided herein shall be made through the sale by the Trustee of the
<PAGE>
 
                                       29

number of shares of Common Stock directed by the Participant. The amount that
may be invested among the otherwise available investment options under the Plan
shall be equal to the proceeds of such sale. Any such diversification shall be
implemented no later than the 180th day of the Plan Year in which the
Participant's direction is made. All such directions shall be in accordance with
any notice, rulings, or regulations or other guidance issued by the Internal
Revenue Service with respect to section 401(a)(28)(B) of the Code. For the
purposes of this section, the term "Qualified Election Period" shall mean the
six (6) Plan Year period beginning with the later of the Plan Year in which the
Participant attains age 55 or completes a Period of Participation of ten (10)
years.

          (d) Notwithstanding subsection (e) below, the Administrator shall 
maintain a General Motors Class H Stock Fund ("Fund H") and Raytheon Company
Class A Stock Fund ("Fund I") as investment options under the Plan, subject to
the limitations prescribed in this subsection (d), for four (4) complete Plan
Years following the Effective Date; provided, however, that if at any time prior
to the expiration of such four (4) year period, the aggregate fair market value
of the assets invested in either Fund H or Fund I falls below five percent (5%)
of the highest fair market value of the assets invested in Fund H or Fund I,
respectively, the Administrator may, with six (6) months written notice to
affected Participants, eliminate Fund H or Fund I, as applicable, as investment
options under the Plan. Notwithstanding the foregoing, the Administrator may
eliminate one or both funds at any time if the Administrator determines in good
faith that such elimination is necessary under applicable law (including without
limitation the prudence requirements of ERISA). When Fund H and Fund I are
eliminated in accordance with this section 5.1(d), Participants with assets
invested in Fund H or Fund I, as applicable, shall direct the transfer of such
assets to other funds available under the Plan or, if no such election is made,
the Administrator shall transfer such assets to a low risk fixed income fund as
determined by the Administrator in its discretion. The only assets that may be
invested in Fund H or Fund I are the General Motors Class H Stock Fund and
Raytheon Company Class A Stock Fund, respectively, directly transferred to the
Plan in connection with the mergers identified in Section 1.1(b). A Participant
may not direct that any other funds in the Participant's Account be invested in
Fund H or Fund I.

           (e) In its discretion, the Administrator may from time to time
designate new funds and, where appropriate, preclude investment in existing
funds and provide for the transfer of Accounts invested in those funds to other
funds selected by the Participant or, if no such election is made, to a low risk
fixed income fund as determined by the Administrator in its discretion.

           (f) Except as otherwise  prescribed in subsections  (b), (c) and (d)
above, a Participant's investment election will apply to the entire Account of 
the Participant.

           (g) In establishing rules and procedures under section 5.1, the
following shall apply:

               (1) Each Participant, Beneficiary or Alternate Payee shall 
affirmatively elect to self-direct the investment of assets in his or her 
Account, but such election may provide for default investments in the absence 
of specific directions from such Participant, Beneficiary or Alternate Payee.
<PAGE>
 
                                       30

               (2) The investment directions of a Participant shall continue to
apply after that Participant's death or incompetence until the Beneficiary (or,
if there is more than one Beneficiary for that Account, all of the 
Beneficiaries), guardian or other representatives provide contrary direction.

               (3) The Administrator may decline to implement investment 
designations  if such investment, in the Administrator's judgment:

                   (A) would result in a prohibited transaction under section 
4975 of the Code;
                   (B) would generate income taxable to the Trust Fund;

                   (C) would not be in accordance with the Plan and Trust;

                   (D) would cause a Fiduciary  to maintain the indicia of
ownership of any assets of the Trust Fund outside the jurisdiction of the 
district  courts of the United States other than as permitted by section 404(b)
of ERISA and Labor Reg. ss.2550.404(b)-1;

                   (E) would jeopardize the Plan's tax qualified status under 
the Code;

                   (F) could result in a loss in excess of the amount credited
to the Account; or

                   (G) would violate any other requirements of the Code or 
ERISA.

               (4) Except as otherwise prescribed in subsections (b), (c) and 
(d) above, the Administrator may establish reasonable restrictions on the
frequency with which investment directions may be given, consistent with section
404(c) of ERISA.

               (5) The  Administrator may establish limits on the use of
brokers, investment counsel or other advisors that may be utilized, including
specifying that all investments must be made through a designated broker or
brokers.

               (6) The Administrator may establish limits on the types of 
investments that are permitted.

          (h) Except as otherwise prescribed in subsections (b), (c) and (d) 
above, the Administrator shall establish such rules and procedures as may be
advisable or necessary to carry out the provisions of this section, with such
rules and procedures being consistent with section 404(c) of ERISA.

involving the investment funds comply with all applicable laws, including the
securities laws.

     5.2  Change in Investment Allocation of Future Deferrals. Except as
otherwise prescribed in sections 5.1(b), (c) and (d), each Participant may elect
to change the investment allocation of future contributions effective as of the
first Trade Day subsequent to notice to the Recordkeeper by which it is
administratively feasible to make such change. Any changes must be made either
in increments of one percent (1%) of the Participant's Account or in a specified
whole dollar amount and must result in a total investment of one hundred percent
(100%) of the Participant's Account.

     5.3  Transfer of Account Balances Between Investment Funds. Except as 
otherwise prescribed in sections 5.1(b), (c) and (d), each Participant may elect
to transfer all or a portion of the amount in his or her Account between
investment funds effective as of the first Trade Day following notice to the
Recordkeeper by which it is administratively feasible to carry out such
transfer. In determining the amount of the transfer, the Participant's Account
shall be valued as of the close of business on the Trade Day on which notice is
received; provided, however, that in any case where the notice is received after
4:00 p.m. Eastern Time (daylight or standard, whichever is in effect on the date
of the call), the Account shall be valued as of the close of business on the
next Trade Day. Such transfers must be made in either one percent (1%)
increments of the entire Account or in a specified amount in whole dollars and,
as of the completion of the transfer, must result in investment of one hundred
percent (100%) of the Account. Transfers shall be effected by telephone notice
to the Recordkeeper.

     5.4  Ownership Status of Funds. The Trustee shall be the owner of
record of the Plan assets. The Administrator shall have records maintained as of
the Valuation Date for each investment option allocating a portion of the
investment option to each Participant who has elected that his or her Account be
invested in such investment option. The records shall reflect each Participant's
portion of Common Stock, Raytheon Company Class A common stock and General
Motors Class H common stock in cash and unitized shares of stock and shall
reflect each Participant's portion of all other investment options as may be
established by the Administrator in a cash amount.

     5.5  Voting Rights. Participants whose Accounts are invested in
Common Stock or Raytheon Company Class A common stock on the last business day
of the second month preceding the record date (the "Voting Eligibility Date")
for any meeting of stockholders have the right to instruct the Trustee as to
voting at such meeting. The number of votes is determined by dividing the value
of the shares in the Participant's Account by the closing price of the
respective classes of stock on the Voting Eligibility Date. If the Trustee has
not received instructions from a Participant as to voting of shares within a
specified time, then the Trustee shall not vote those shares. If a Participant
furnishes the Trustee with a signed vote direction card without indicating a
voting choice thereon, the Trustee shall vote the Participant's shares as
recommended by management. In addition, each Participant shall have the right to
accept or reject any tender or exchange offer for shares of the respective
classes of stock. The Trustee shall vote (or tender or exchange) all combined
fractional shares of the respective classes of stock to the extent possible in
the same proportion as the shares which have been voted (or tendered or
exchanged) by each Participant. Any instructions as to voting (or tender or
exchange) received from an individual Participant shall be held in confidence by
the Trustee and shall not be divulged to the Adopting Employers or to any
officer or employee thereof or to any other person.

     5.6 Allocation of Earnings.

        (a)(1) The Administrator, as of each Valuation Date, shall adjust the
amounts credited to the Accounts (including Accounts for persons who are no
longer Employees) so that the total of such Account balances equals the fair
market value of the Trust Fund assets as of such Valuation Date. Except as
otherwise provided herein, any changes in the fair market value of the Trust
Fund assets since the preceding Valuation Date shall be charged or credited to
each Account in the ratio that the balance in each such Account as of the
preceding Valuation Date bears to the balances in all Accounts as of that
Valuation Date with appropriate adjustments to reflect any distributions,
allocations or similar adjustments to such Account or Accounts since that
Valuation Date.

           (2) To the extent that separate investment funds are established (as 
provided in section 5.1(a)), the adjustments required by subsection (a)(1) shall
be made by applying subsection (a)(1) separately for each such investment fund
so that any changes in the net worth of each such investment fund are charged or
credited to the portion of each Account invested in such investment fund in the
ratio that the portion of each such Account invested in such investment fund as
of the preceding Valuation Date (reduced by any distributions made from that
portion of such Account since that Valuation Date) bears to the total amount
credited to such investment funds as of that Valuation Date (reduced by
distributions made from such investment fund since that Valuation Date).

           (3) Interim valuations, in accordance with the foregoing procedure, 
may be made at such time or times as the Administrator directs.

              (b) The Administrator may, in its sole discretion, direct the 
Trustee to segregate and separately invest any Trust Fund assets. If any assets
are segregated in this fashion, the earnings or losses on such assets shall be
determined apart from other Trust assets and shall be adjusted on each Valuation
Date, or at such other times as the Administrator deems necessary, in accordance
with this section.

Participant's Elective Deferral, Employee After-Tax Contribution, Rollover
Contribution, Qualified Nonelective Contribution and ESOP Contribution Accounts.

     6.2 Matching Contribution Account.

         (a) Each Participant who performs an Hour of Service on or after

Account, including the Participant's Matching Contribution Account.
<PAGE>
 
                                       33

         (b) Each Participant who does not perform an Hour of Service on or 
after January 1, 1999 shall have a nonforfeitable right to his or her
Matching Contribution Account in accordance with the terms of the Plan as in
effect before January 1, 1999 (or, if more favorable, under the terms of the
transferee plan in the case of a direct transfer of assets to the Plan in
accordance with sections 1.1(b) and 4.5(c)). For this purpose, before January 1,
1999, the Plan provided that each Participant would have a nonforfeitable right
to his or her Matching Contribution Account upon the earliest of:

             (1) the Participant's completion of a Period of Service of five
(5) years;

             (2) the Participant's completion of a Period of Participation of 
three (3) years;

             (3) the  Participant's Retirement, death while an Employee, 
Disability  or attainment of Normal Retirement Age; or

             (4) in the case of a Participant who formerly participated in the
Raytheon Salaried Savings and Investment Plan (10011) and the Raytheon
California Hourly Savings and Investment Plan (10012), the Participant's Layoff
or Severance from Service due to Qualified Military Service.

     6.3 Forfeitures.

         (a) In the event that a Participant incurs a Severance from Service 
before attaining a nonforfeitable right to his or her Matching Contributions,
the Matching Contribution Account will be forfeited as of the first day of the
month immediately following the earliest of: (i) the date on which the
Participant incurs a Period of Severance of five (5) consecutive years; (ii)
death; or (iii) the date on which the Participant's Elective Deferral Account is
distributed in accordance with ARTICLE VIII. Forfeitures of Matching
Contributions will be used to reduce future contributions of the Adopting
Employers to the Plan.

         (b) If, in connection with his or her Severance from Service,
a Participant received a distribution of his or her Elective Deferral Account
when he or she did not have a nonforfeitable right to his or her Matching
Contribution Account, the Matching Contributions that were forfeited, unadjusted
by any subsequent gains or losses, shall be restored if he or she again becomes
an Employee before incurring a Period of Severance of five (5) consecutive
years.

     6.4 Break in Service Rules

         (a) Periods of Service.  In determining the length of a Period of 
Service, the Administrator shall include all Periods of Service, except the
following Periods of Service shall not be taken into account:

            (1) in the case of a Participant who has never had a vested account
balance, the Period of Service before any Period of Severance which equals or
exceeds five (5) consecutive years; and
<PAGE>
 
                                       34

            (2) in the case of a Participant who has had a vested account
balance and who has incurred a Period of Severance which equals or exceeds five
(5) years, the Period of Service after such Period of Severance shall not be
taken into account for purposes of determining the nonforfeitable interest of
such Participant in the Matching Contributions allocated to his or her Account
before such Period of Severance.

         (b) Periods of Severance.  In determining the length of a Period of 
Service, the Administrator shall include any period of time beginning on an
Employee's Severance from Service Date and ending on the date on which he or she
is next credited with an Hour of Service, provided that such Hour of Service is
credited within the twelve- (12) consecutive month period following such
Severance from Service Date.

         (c) Other Periods. In making the determinations described in
subsections (a) and (b) of this section, the second, third, and fourth
consecutive years of a Layoff (from the first anniversary of the last day paid
to the fourth anniversary of the last day paid) and any period in excess of one
(1) year of an Authorized Leave of Absence shall be regarded as neither a Period
of Service nor a Period of Severance.

                                   ARTICLE VII

                             In-Service Withdrawals

     7.1 Elective Deferrals and Qualified Nonelective Contributions.

         (a) Subject to the terms and conditions prescribed in section 7.5, a
 Participant may withdraw all or a portion of his or her Elective Deferral
Account or Qualified Nonelective Contribution Account either (1) on or after
attainment of age fifty-nine and one-half (59 1/2), or (2) in the event of a
hardship.

         (b) In order to be entitled to a hardship withdrawal under this 
section, a Participant must satisfy the requirements of both subsection (c) and
subsection (d). Whether a Participant is entitled to a withdrawal under this
section is to be determined by the Administrator in accordance with
nondiscriminatory and objective standards.

         (c)(1) A Participant will be deemed to have experienced an immediate 
and heavy financial need necessary to satisfy the requirements of this
subsection if the withdrawal is on account of:

               (A) medical expenses described in section 213(d) of the Code 
incurred by the Participant, the Participant's spouse or any dependents of the
Participant;

               (B) the purchase (excluding mortgage payments) of a principal
residence of the Participant;

               (C) payment of tuition for the next twelve (12) months of 
post-secondary education for the Participant or his or her spouse, children or
dependents; or
<PAGE>
 
                                       35

               (D) the need to prevent the eviction of the Participant from his
or her principal residence or the foreclosure on the mortgage of the 
Participant's principal residence.

            (2) The  Administrator may, on the basis of such evidence it deems
relevant, determine that the Participant has experienced an immediate and heavy 
financial need for reasons other than those enumerated above in this subsection.

         (d)(1) A withdrawal under this subsection will be deemed necessary to
satisfy an immediate and heavy financial need of the Participant if it satisfies
the requirements of this subsection. To the extent the amount of the withdrawal
would be in excess of the amount required to relieve the financial need of the
Participant or to the extent such need may be satisfied from other resources
that are reasonably available to the Participant, such withdrawal shall not
satisfy the requirements of this subsection. For purposes of this subsection, a
Participant's resources shall be deemed to include those assets of his or her
spouse or minor children that are reasonably available to the Participant.

            (2) A withdrawal may be treated as necessary to satisfy a financial
need if the Administrator reasonably relies upon the Participant's 
representation that the need cannot be relieved:

                (A) through reimbursement or compensation by insurance or 
otherwise;

                (B) by reasonable liquidation of the Participant's assets to 
the extent such liquidation would not itself cause an immediate and heavy 
financial need;

                (C) by cessation of Elective Deferrals under the Plan for at
least twelve (12) months after receipt of the hardship withdrawal; or

                (D) by other distributions or nontaxable (at the time of the 
loan) loans from plans maintained by the Adopting Employers or by any other
employer or by borrowing from commercial sources on reasonable commercial terms.

         (e) If a Participant receives a withdrawal for reasons of financial
hardship, the Participant's Elective Deferrals shall be reduced to four percent
(4%) (or such lower percentage as the Participant shall thereafter designate),
if in excess thereof as of the date of the distribution, and shall not be
increased during the twelve (12) months immediately subsequent to the date of
distribution.

     7.2 Employee After-Tax Contributions. Subject to the terms and conditions
prescribed in section 7.5, a Participant may withdraw all or a portion of his 
or her Employee After-Tax Contribution Account.

     7.3  Matching Contributions. Subject to the terms and conditions
prescribed in section 7.5, after completion of a Period of Participation of five
(5) years or more, a Participant may withdraw all or a portion of his or her
Matching Contribution Account.

     7.4  Rollover Contributions. Subject to the terms and conditions
prescribed in section 7.5, a Participant may withdraw all or a portion of his or

to the following terms and conditions:

          (a) In-service withdrawals of less than five hundred dollars ($500)
 will not be permitted.

          (b) In determining the amount of any in-service withdrawal, the
Participant's Account shall be valued as of the close of business on the Trade
Day on which notice is received; provided, however, that in any case where the
notice is received after 4:00 p.m. Eastern Time (daylight or standard, whichever
is in effect on the date of the call), the Account shall be valued as of the
close of business on the next Trade Day.

          (c) Payment of the amount withdrawn will be made as soon as
administratively feasible after the effective date of the withdrawal.

          (d) In-service withdrawals from a Participant's Account will
generally be made in cash. However, in-service withdrawals from Accounts
invested in Common Stock, General Motors Class H common stock or Raytheon
Company Class A common stock will be made in cash or stock (with cash for
fractional or unissued shares) as elected by the Participant.

          (e) Funds for in-service withdrawals will be taken on pro-rata basis
against the Participant's investment balances in his or her Account.

          (f) In-service withdrawals may not be redeposited in the Plan.

          (g) The Administrator may adopt such other rules and procedures as it
deems necessary, in its sole discretion, to properly administer the in-service
withdrawal provisions in this ARTICLE.

     8.3 Form of Distribution.

close of business on the next Trade Day.

     8.5 Direct Rollovers.

that would otherwise be paid as an Eligible Rollover Distribution shall instead

          (c) An election to have payment made in a Direct Rollover shall only
be valid if the Participant or other Distributee provides adequate

            (2) During any period in which the issue of whether a Domestic 
Relations Order is a Qualified Domestic Relations Order is being determined, the
Administrator shall separately account for the amounts that would have been
payable to the Alternate Payee during such period if the order had been
determined to be a Qualified Domestic Relations Order.

         (c)(1) A Domestic Relations Order meets the requirements of this
subsection only if such order clearly specifies the following:

               (A) the name and last known mailing address (if any) f the 
Participant and the name and mailing address of each Alternate Payee covered by
the order;

                                       41

               (B) the amount or the percentage of the Participant's benefits to
be paid by the Plan to each such Alternate Payee or the manner in which such
amount or percentage is to be determined;

               (C) the number of payments or period to which such order applies;
 and

               (D) each plan to which such order applies.

            (2) A Domestic Relations Order meets the requirements of this 
subsection only if such order does not:

               (A) require the Plan to provide any type or form of benefit or
any option not otherwise provided under the Plan;

               (B) require the Plan to provide increased benefits (determined on
the basis of actuarial value); and

               (C) does not require the payment of benefits to an Alternate
Payee that is required to be paid to another Alternate Payee under another order
previously determined to be a Qualified Domestic Relations Order.

          (d) A domestic relations order shall not be treated as failing to meet
the requirements of section 8.7(c)(2)(A) solely because such order requires that
payment of benefits be made to an Alternate Payee:

             (1) in the case of any payment before a Participant has separated
from service, on or after the date on which the Participant attains (or would
have attained) the Earliest Retirement Date;

             (2) as if the Participant had retired on the date on which such
payment is to begin under such order (but taking into account only the present
value of the benefits actually accrued and not taking into account the present
value of any employer subsidy for early retirement); and

             (3) in any form in which such benefits may be paid under the Plan 
to the Participant (other than in the form of a qualified joint and survivor
annuity with respect to the Alternate Payee and his or her subsequent spouse).

          (e) A domestic relations order shall not be treated as failing to meet
the requirements of section 8.7(c)(2)(A) solely because such order requires that
payment of benefits be made to an Alternate Payee at a date before the
Participant is entitled to receive a distribution. Such distribution shall be
made to such Alternate Payee notwithstanding any contrary provision of the Plan.

          (f) The following terms shall have the meanings specified:

              (1) Alternate Payee. Any spouse, former spouse, child or other 
dependent of a Participant who is recognized by a Domestic Relations Order as
having a right to benefits under the Plan with respect to such Participant.

              (2) Domestic Relations Order. A judgment, decree or order relating
to child  support, alimony or marital property rights, as defined in section 
414(p)(1)(B) of the Code.

              (3) Earliest Retirement Date.  The earlier of:

                  (A) the date on which the Participant is entitled to a 
distribution under the Plan; or

                  (B) the later of:

                      (i) the date the Participant attains age fifty (50); or

                                       42

                     (ii) the earliest date on which the Participant could begin
 receiving benefits under the Plan if the Participant separated from service.

              (4) Qualified Domestic Relations Order. A Domestic Relations Order
that satisfies the requirements of subsection (c) and section 414(p)(1)(A) of
the Code.

          (g) If an Alternate Payee entitled to payment under this section is
the spouse or former spouse of a Participant and payment will otherwise be
