         Item 5.   Other Events.

                   On January 16, 1997, the Registrant entered into an
         Agreement and Plan of Merger (the "Merger Agreement") with HE
         Holdings, Inc. ("HEH"), a Delaware corporation and an indirect,
         wholly owned subsidiary of General Motors Corporation, a
         Delaware corporation ("GM"), pursuant to which the Registrant
         agreed to merge with and into HEH (the "Merger").  Prior to
         consummation of the Merger, GM and certain of its affiliates
         will consummate certain transactions, including a spinoff of
         HEH (which will then consist primarily of the aerospace and
         defense systems businesses of Hughes Electronics Corporation,
         the parent corporation of HEH) to GM stockholders.  The
         Registrant and GM have entered into an Implementation
         Agreement, dated as of January 16, 1997, relating to certain of
         these transactions (the "Implementation Agreement").

                   In the Merger, holders of the common stock of
         Registrant (the "Common Stock") will receive one share of a new
         Class B common stock of the surviving corporation for each
         share of Common Stock owned at the effective time of the
         Merger, which shares of Class B common stock will represent, in
         the aggregate, 70% of the equity in the surviving corporation.
         The common equity of HEH distributed to GM stockholders will
         represent, following the Merger, in the aggregate, 30% of the
         equity of the surviving corporation in the form of shares of
         Class A common stock.  The holders of Class A common stock will
         have, in the aggregate, 80.1% of the voting power, and the
         holders of Class B common stock will have, in the aggregate,
         19.9% of the voting power in the election of directors.  On all
         other matters, the holders of Class A common stock and Class B
         common stock will vote as separate classes.

                   Prior to the Merger, the Registrant has agreed that
         HEH may borrow, and become liable to repay, approximately $4.4
         billion, which amount will be contributed by HEH to GM or
         another affiliate of GM that is not a subsidiary of HEH and the
         proceeds of which will therefore not be assets of HEH as of the
         time of the Merger.  The actual amount will be determined by
         subtracting from $9.5 billion any other outstanding debt of HEH
         as of the Effective Time and the product of (x) the number of
         shares of Class A common stock to be issued to GM stockholders
         (102,630,503 shares) and (y) the average closing market price
         of the Common Stock during the 30-day period ending on the
         fifth day prior to consummation of the Merger; provided that in
         the event such average price is less than $44.42, it will be
         deemed to be $44.42, and in the event such price is more than
         $54.29, it shall be deemed to be $54.29.<PAGE>







                   Consummation of the transactions is subject to
         satisfaction of various conditions, including the approval of
         the Merger by a majority of the holders of Common Stock,
         determination by the GM Board of Directors of the proportion of
         Class A common stock of the surviving corporation to be
         distributed to the holders of GM common stock and GMH stock,
         finalization by GM of the details of the internal transfers
         that will precede the Merger, the approval of the transactions
         by the holders of GM common stock and GMH stock, expiration or
         termination of any applicable waiting period under the Hart-
         Scott-Rodino Antitrust Improvements Act of 1976, as amended,
         receipt by GM of a ruling of the Internal Revenue Service
         relating to certain federal tax consequences of the
         transactions and other customary conditions.

                   A copy of each of the Merger Agreement and the
         Implementation Agreement is attached hereto as Exhibit 2.1 and
         Exhibit 2.2, respectively, and each is incorporated herein by
         reference, and the descriptions contained herein of such
         agreements and the transactions contemplated thereby are
         qualified in their entirety by reference to such Exhibits.

                   In connection with entering into the Merger
         Agreement, on January 16, 1997, the Registrant issued a press
         release, a copy of which is attached hereto as Exhibit 99.1 and
         is incorporated herein by reference.<PAGE>

                           AGREEMENT AND PLAN OF MERGER

                   This Agreement and Plan of Merger (this "Agreement")
         is made and entered into as of January 16, 1997, by and between
         HE Holdings, Inc., a Delaware corporation ("Hughes"), and
         Raytheon Company, a Delaware corporation ("Raytheon").

                   WHEREAS, Hughes and Raytheon desire to combine
         Raytheon's business with the Defense Business (as defined in
         the Separation Agreement (as hereinafter defined), the "Defense
         Business"), through a merger pursuant to which Raytheon shall
         merge (the "Merger") with and into Hughes, with Hughes as the
         surviving corporation, and each share of Raytheon Common Stock
         (as defined herein) outstanding at the Effective Time (as
         defined herein) will be converted into a share of Hughes Class
         B Common Stock (as defined herein) as more fully provided
         herein; and

                   WHEREAS, prior to the Effective Time, Hughes shall
         adopt the restated certificate of incorporation and restated
         by-laws attached as Exhibits A and B, respectively, which
         provide for, among other things, a recapitalization of the
         outstanding capital stock of Hughes into Class A common stock,
         par value $0.01 per share ("Hughes Class A Common Stock"), and
         provide also for a Class B common stock, par value $0.01 per
         share ("Hughes Class B Common Stock"); and

                   WHEREAS, as a condition to entering into this
         Agreement, Raytheon has required that Hughes be, at the time of
         consummation of the Merger, an independent, publicly owned
         company, comprising the Defense Business; and

                   WHEREAS, concurrently with the execution and delivery
         of this Agreement, General Motors Corporation ("GM"), a
         Delaware corporation and the indirect parent of Hughes, and
         Raytheon are entering into an Implementation Agreement dated as
         of the date hereof, in the form attached as Exhibit C (the "GM
         Implementation Agreement"), setting forth, among other things,
         the rights and obligations of GM with respect to the execution
         and delivery of the Hughes Distribution Agreement (as defined
         below); and

                   WHEREAS, prior to the Effective Time, subject to the
         satisfaction or waiver of the conditions set forth in the GM
         Implementation Agreement, GM and a wholly owned subsidiary of
         GM to be designated by GM ("Merger Sub") will enter into an
         Agreement and Plan of Merger, in the form attached as Exhibit D
         or with such changes thereto as are permitted pursuant to the
         GM Implementation Agreement (the "Hughes Distribution
         Agreement"), and immediately prior to the Effective Time, shall
         consummate the GM Transactions (as defined therein, the "GM
         Transactions") in accordance with the terms and subject to the
         conditions thereof.  Pursuant to the Hughes Distribution
         Agreement, Merger<PAGE>







         Sub shall merge with and into GM, with GM as the surviving
         corporation (the "GM Merger"), and, pursuant thereto, among
         other things, holders of shares of common stock, par value $1
         2/3 per share, of GM (the "GM $1 2/3 Common Stock") and of
         Class H common stock, par value $0.10 per share, of GM (the "GM
         Class H Common Stock") will receive in accordance with the
         Hughes Distribution Ratio (as defined in the GM Implementation
         Agreement) a distribution of shares of Hughes Class A Common
         Stock on account of their holdings of such GM $1 2/3 Common
         Stock and GM Class H Common Stock, such that, prior to the
         consummation of the Merger, such shares of Hughes Class A
         Common Stock shall represent the entire equity interest in
         Hughes; and  

                   WHEREAS, the parties intend that (a) the Merger
         constitute a tax-free "reorganization" within the meaning of
         Section 368(a) of the Internal Revenue Code of 1986, as amended
         (the "Code"), and (b) certain of the transactions contemplated
         by the Hughes Distribution Agreement qualify as tax-free spin-
         offs within the meaning of Sections 355 and 368(a)(1)(D) of the
         Code; and

                   WHEREAS, the respective Boards of Directors of GM,
         Hughes and Raytheon have determined that the Merger is
         desirable and in the best interests of their respective common
         stockholders and, by resolutions duly adopted, the respective
         Boards of Directors of Hughes and Raytheon have approved and
         adopted this Agreement and the respective Boards of Directors
         of GM and Raytheon have approved and adopted the GM
         Implementation Agreement;

                   NOW, THEREFORE, in consideration of the premises and
         the representations, warranties, covenants and agreements
         contained herein, and for other good and valuable
         consideration, the receipt and sufficiency of which are hereby
         acknowledged, and intending to be legally bound hereby, the
         parties hereto hereby agree as follows:


                                    ARTICLE 1

                                    THE MERGER

                   Section 1.1.  The Merger.  Upon the terms and subject
         to the conditions hereof, and in accordance with the provisions
         of the Delaware General Corporation Law (the "DGCL"), Raytheon
         shall be merged with and into Hughes as soon as practicable
         following the satisfaction or waiver of the conditions set
         forth in Article 6.  Following the Merger, the separate
         corporate existence of Raytheon shall cease and Hughes shall
         continue its existence


                                       -2-<PAGE>







         under the laws of the State of Delaware.  Hughes, in its
         capacity as the corporation surviving the Merger, is
         hereinafter sometimes referred to as the "Surviving
         Corporation".

                   Section 1.2.  Effective Time.  The Merger shall be
         consummated by filing with the Secretary of State of the State
         of Delaware (the "Delaware Secretary of State") a certificate
         of merger (the "Certificate of Merger") in such form as is
         required by and executed in accordance with the DGCL.  The
         Merger shall become effective (the "Effective Time") when the
         Certificate of Merger has been filed with the Delaware
         Secretary of State or at such later time as shall be specified
         in the Certificate of Merger, which shall be immediately
         following the consummation of the GM Merger.  Prior to the
         filing referred to in this Section 1.2, a closing shall be held
         at the New York offices of Weil, Gotshal & Manges LLP, or such
         other place as Hughes and Raytheon may agree on a date (the
         "Closing Date") mutually agreed to by Hughes and Raytheon. 

                   Section 1.3.  Effects of The Merger.  The Merger
         shall have the effects set forth in Section 259 of the DGCL.

                   Section 1.4.  Certificate of Incorporation and By-
         laws.  Unless the same already shall have been adopted, the
         Certificate of Merger shall provide that at the Effective Time
         (i) the Certificate of Incorporation of the Surviving
         Corporation shall be the certificate of incorporation attached
         as Exhibit A (except as regards the corporate name), (ii) the
         By-laws of the Surviving Corporation shall be the By-laws
         attached as Exhibit B and (iii) the corporate name of the
         Surviving Corporation shall be "Raytheon Company."

                   Section 1.5.  Boards, Committees and Officers.  At
         the Effective Time, the Board of Directors, committees of the
         Board of Directors, composition of such committees (including
         chairmen thereof) and certain officers of the Surviving
         Corporation (as indicated on Exhibit E) shall be as set forth
         on Exhibit E until the earlier of the resignation or removal of
         any individual listed on or designated in accordance with
         Exhibit E or until their respective successors are duly
         appointed or elected and qualified, as the case may be. Hughes
         shall create, effective from and after the Effective Time, the
         following three new committees:  a Management Transition
         Committee which shall be responsible for supervising and
         implementing the integration of the businesses, facilities,
         functions and employees of Hughes, Raytheon and the Defense
         Systems and Electronics business of Texas Instruments
         Incorporated to be acquired by Raytheon, which shall be chaired
         by an individual who prior to the Effective Time is an
         executive officer of Hughes; a Board Transition Committee which
         shall be responsible for resolving issues relating to such
         integration at the Board of Directors level; and a Defense
         Business Executive Council which shall supervise and manage the
         combined defense businesses of Hughes, Raytheon and the Defense
         Systems and Electronics


                                       -3-<PAGE>







         business of Texas Instruments Incorporated to be acquired by
         Raytheon, on an ongoing basis and shall serve as a vehicle for
         planning, communication and decision making on issues involving
         such combined businesses.  The composition of such committees
         also shall be as set forth on Exhibit E until the earlier of
         the resignation or removal of any individual listed on or
         designated in accordance with Exhibit E or until their
         respective successors are duly appointed or elected and
         qualified, as the case may be.  If any officer listed on or
         appointed in accordance with Exhibit E ceases to be a full-time
         employee of Hughes or Raytheon prior to the Effective Time, or
         if any director, committee member or committee chairman listed
         or designated on Exhibit E is not available to serve as such at
         the Effective Time, the parties shall agree upon another person
         to serve in such person's stead.  On or prior to the Effective
         Time, Hughes, to the extent necessary, shall deliver to
         Raytheon evidence of the resignations of the directors of
         Hughes not so designated to be continuing to serve as directors
         of the Surviving Corporation, such resignations to be effective
         as of the Effective Time.

                   Section 1.6.  Additional Actions.  If, at any time
         after the Effective Time, the Surviving Corporation shall
         consider or be advised that any further deeds, assignments or
         assurances in law or any other acts are necessary or desirable
         to (a) vest, perfect or confirm, of record or otherwise, in the
         Surviving Corporation its right, title or interest in, to or
         under any of the rights, properties or assets of Raytheon or
         Hughes, or (b) otherwise carry out the provisions of this
         Agreement, Raytheon and its directors and officers shall be
         deemed to have granted to the Surviving Corporation an
         irrevocable power of attorney to execute and deliver all such
         deeds, assignments or assurances in law and to take all acts
         necessary, proper or desirable to vest, perfect or confirm
         title to and possession of such rights, properties or assets in
         the Surviving Corporation and otherwise to carry out the
         provisions of this Agreement, and the directors and officers of
         the Surviving Corporation are authorized in the name of Hughes
         or Raytheon, as the case may be, or otherwise to take any and
         all such action.


                                    ARTICLE 2

                             CONVERSION OF SECURITIES

                   Section 2.1.  Conversion of Capital Stock.  At the
         Effective Time, by virtue of the Merger and without any action
         on the part of Hughes, Raytheon, any holder of Hughes Class A
         Common Stock, any holder of Raytheon Common Stock or any other
         person:

                   (a)  Subject to Section 2.3 below, each whole share
         of Hughes Class A Common Stock that is issued and outstanding
         immediately prior to the Effective Time shall


                                       -4-<PAGE>







         remain outstanding and shall be unchanged after the Merger, and
         each fractional share of Hughes Class A Common Stock that is
         issued and outstanding immediately prior to the Effective Time
         shall be converted into and represent an equivalent fractional
         share of Hughes Class B Common Stock (which shall be sold by
         the Exchange Agent as provided in Section 2.3 below).  For
         purposes of determining whether a holder of Hughes Class A
         Common Stock immediately prior to the Effective Time holds a
         fractional share of Hughes Class A Common Stock, all shares of
         Hughes Class A Common Stock held by such holder shall be
         aggregated;

                   (b)  Each share of common stock, par value $1.00 per
         share, of Raytheon ("Raytheon Common Stock") issued and
         outstanding immediately prior to the Effective Time shall be
         converted into and represent one share of Hughes Class B Common
         Stock; and

                   (c)  Each share of capital stock of Raytheon held in
         the treasury of Raytheon or owned by any wholly-owned
         subsidiary of Raytheon shall be cancelled and retired and no
         payment shall be made in respect thereof.

                   Section 2.2.  Exchange of Certificates.

                   (a)  Exchange Agent.  Following the Effective Time,
         Hughes shall deposit with the exchange agent mutually agreed to
         and designated by Hughes and Raytheon (the "Exchange Agent"),
         as required for exchange in accordance with this Section 2.2,
         certificates representing shares of Hughes Class B Common Stock
         issuable pursuant to Section 2.1 in exchange for outstanding
         shares of Raytheon Common Stock and cash, as required for
         payments pursuant to Section 2.2(c) below (such shares of
         Hughes Class B Common Stock, together with any cash deposited
         with the Exchange Agent pursuant to this Section 2.2, being
         hereinafter referred to as the "Exchange Fund.")

                   (b)  Exchange Procedures.  As soon as practicable
         after the Effective Time, the Exchange Agent, pursuant to the
         terms of an exchange agent agreement to be entered into with
         Hughes prior to the Effective Time, shall mail to each holder
         of record of a certificate or certificates (the "Certificates")
         which immediately prior to the Effective Time represented
         outstanding shares of Raytheon Common Stock whose shares were
         converted into shares of Hughes Class B Common Stock pursuant
         to Section 2.1(b): (i) a letter of transmittal (which shall
         specify that delivery shall be effected, and risk of loss and
         title to the Certificates shall pass, only upon delivery of the
         Certificates to the Exchange Agent and shall be in such form
         and have such other provisions as Hughes and Raytheon may
         specify), and (ii) instructions for effecting the surrender of
         the Certificates in exchange for certificates representing
         shares of Hughes Class B Common Stock.  Upon surrender of a
         Certificate for cancellation to the


                                       -5-<PAGE>







         Exchange Agent, together with a duly executed letter of
         transmittal, the holder of such Certificate shall be entitled
         to receive in exchange therefor (x) a certificate representing
         that number of shares of Hughes Class B Common Stock which such
         holder has the right to receive pursuant to Section 2.1 and (y)
         a check representing the unpaid dividends and distributions, if
         any, which such holder has the right to receive pursuant to the
         provisions of this Article, after giving effect to any required
         withholding tax pursuant to Section 2.4(c) below, and the
         shares represented by the Certificate so surrendered shall
         forthwith be cancelled.  No interest will be paid or accrued on
         unpaid dividends and distributions, if any, payable to holders
         of Raytheon Common Stock ("Raytheon Stockholders").  In the
         event of a transfer of ownership of shares of Raytheon Common
         Stock which is not registered on the transfer records of
         Raytheon, a certificate representing the proper number of
         shares of Hughes Class B Common Stock, together with a check
         for the cash to be paid in lieu of unpaid dividends and
         distributions, if any, may be issued to such transferee if the
         Certificate representing such shares of Raytheon Common Stock
         held by such transferee is presented to the Exchange Agent,
         accompanied by all documents required to evidence and effect
         such transfer and to evidence that any applicable stock
         transfer taxes have been paid.  Until surrendered as
         contemplated by this Section 2.2, each Certificate shall be
         deemed at any time after the Effective Time to represent that
         number of whole shares of Hughes Class B Common Stock into
         which the shares of Raytheon Common Stock formerly represented
         by such Certificate shall have been converted, together with
         the right to receive any unpaid dividends and distributions.

                   (c)  Distributions With Respect to Unexchanged
         Shares.  Notwithstanding any other provisions of this
         Agreement, no dividends or other distributions declared or made
         after the Effective Time with respect to shares of Hughes Class
         B Common Stock having a record date after the Effective Time
         shall be paid to the holder of any unsurrendered Certificate,
         until the holder shall surrender such Certificate as provided
         in this Section 2.2. Subject to the effect of Applicable Law
         (as defined herein), following surrender of any such
         Certificate, there shall be paid to the holder of the
         certificates representing whole shares of Hughes Class B Common
         Stock issued in exchange therefor, without interest, (i)
         promptly following such surrender, the amount of dividends or
         other distributions with a record date after the Effective Time
         theretofore payable with respect to such whole shares of Hughes
         Class B Common Stock and not paid, less the amount of any
         withholding taxes which may be required thereon pursuant to
         Section 2.4(c) below, and (ii) at the appropriate payment date
         subsequent to surrender, the amount of dividends or other
         distributions with a record date after the Effective Time but
         prior to surrender and a payment date subsequent to surrender
         payable with respect to such whole shares of Hughes Class B
         Common Stock, less the amount of any withholding taxes which
         may be required thereon.

                   (d)  No Further Ownership Rights in Raytheon Common
         Stock.  All shares of Hughes Class B Common Stock issued upon
         surrender of Certificates in accordance with the terms hereof
         (including any cash paid pursuant to this Article 2) shall be
         deemed to have been issued in full satisfaction of all rights
         pertaining to such shares of Raytheon Common Stock represented
         thereby, and from and after the Effective Time there shall be
         no further registration of transfers of shares of Raytheon
         Common Stock on the stock transfer books of Raytheon.  If,
         after the Effective Time, Certificates are presented to the
         Surviving Corporation for any reason, they shall be cancelled
         and exchanged as provided in this Section 2.2.

                   Section 2.3.  No Fractional Share Certificates.

                   (a)  Determination of Excess Shares.  As promptly as
         practicable following the Effective Time, the Exchange Agent
         shall determine the aggregate number of fractional shares of
         Hughes Class A Common Stock converted into Hughes Class B
         Common Stock pursuant to Section 2.1(a) (such aggregate number
         of shares being herein called the "Excess Shares").  Following
         the Effective Time, the Exchange Agent, as agent for the
         holders of GM Common Stock, shall sell the Excess Shares at
         then prevailing prices on the New York Stock Exchange, Inc.
         (the "NYSE"), all in the manner provided in subsection (b) of
         this Section 2.3.

                   (b)  Common Shares Trust.  The sale of the Excess
         Shares by the Exchange Agent shall be executed on the NYSE
         through one or more member firms of the NYSE and shall be
         executed in round lots to the extent practicable.  The Exchange
         Agent shall use all reasonable efforts to complete the sale of
         the Excess Shares as promptly following the Effective Time as,
         in the Exchange Agent's reasonable judgment, is practicable
         consistent with obtaining the best execution of such sales in
         light of prevailing market conditions.  Until the net proceeds
         of  such sale or sales have been distributed to the holders of
         Hughes Class B Common Stock constituting Excess Shares, the
         Exchange Agent will hold such proceeds in trust for the holders
         of such Hughes Class B Common Stock (the "Common Shares
         Trust"). The Surviving Corporation shall pay all commissions,
         transfer taxes and other out-of-pocket transaction costs,
         including the expenses and compensation of the Exchange Agent,
         incurred in connection with such sale of the Excess Shares.
         The Exchange Agent shall determine the portion of the Common
         Shares Trust to which each holder of such fractional interests
         in Hughes Class B Common Stock shall be entitled, if any, by
         multiplying the amount of the aggregate net proceeds comprising
         the Common Shares Trust by a fraction the numerator of which is
         the amount of fractional share interests to which such holder
         of Hughes Class B Common Stock is entitled and the denominator
         of which is the aggregate amount of fractional share interests
         to which all such holders of Hughes Class B Common Stock are
         entitled.

                   (c)  Distribution to Holders of Fractional Hughes
         Class B Common Stock.   As soon as practicable after the
         determination of the amount of cash, if any, to be paid to
         holders of Hughes Class B Common Stock with respect to any
         fractional share interests, the Exchange Agent shall make
         available such amounts, net of any required withholding, to
         such holders of Hughes Class B Common Stock, subject to and in
         accordance with the terms of this Agreement.

                   Section 2.4.  Exchange Fund and Common Shares Trust
         Matters.

                   (a)  No Liability.  None of any party hereto, the
         Exchange Agent or the Surviving Corporation shall be liable to
         any person in respect of any shares of Hughes Class B Common
         Stock (or dividends or distributions with respect thereto) or
         cash from the Exchange Fund or the Common Shares Trust
         delivered to a public official pursuant to any applicable
         abandoned property, escheat or similar law.  If any
         Certificates shall not have been surrendered prior to seven
         years after the Effective Time (or immediately prior to such
         earlier date on which any cash, any dividends or distributions
         with respect to whole shares of Hughes Class B Common Stock in
         respect of such Certificate would otherwise escheat to or
         become the property of any Governmental Authority (as defined
         herein)), any such cash, dividends or distributions in respect
         of such Certificate shall, to the extent permitted by
         Applicable Law (as defined in Section 3.8 hereof), become the
         property of the Surviving Corporation, free and clear of all
         claims or interest of any person previously entitled thereto.

                   (b)  Investment of Exchange Fund.  The Exchange Agent
         shall invest any cash included in the Exchange Fund and the
         Common Shares Trust, as directed by the Surviving Corporation,
         on a daily basis.  Any interest and other income resulting from
         such investments shall be paid to the Surviving Corporation
         from time to time as the Surviving Corporation may request.

                   (c)  Withholding Rights.  The Exchange Agent, on
         behalf of the Surviving Corporation, shall be entitled to
         deduct and withhold from the consideration otherwise payable
         pursuant to this Agreement to any holder of Raytheon Common
         Stock and to any holder of fractional interests in Hughes Class
         B Common Stock as set forth in Section 2.3 above, such amounts
         as may be required to be deducted and withheld with respect to
         the making of such payment under the Code, or under any
         provision of state, local or foreign tax (as defined herein)
         law.  To the extent that amounts are so withheld and paid over
         to the appropriate taxing authority, such withheld amounts will
         be treated for all purposes of this Agreement as having been
         paid to the holder of Raytheon Common Stock or Hughes Class B
         Common Stock, as the case may be, in respect of which such
         deduction and withholding was made.

                   (d)  Termination of Exchange Fund and Common Shares
         Trust.  Any portion of the Exchange Fund and the Common Shares
         Trust which remains undistributed for six months after the
         Effective Time shall be delivered to the Surviving Corporation,
         and any holders of fractional interests in Hughes Class B
         Common Stock or any holders of Raytheon Common Stock
         representing Hughes Class B Common Stock who have not
         theretofore complied with the provisions of this Article 2
         shall thereafter look only to the Surviving Corporation for
         satisfaction of their claims for Hughes Class B Common Stock,
         dividends and other distributions, if any, and, with respect to
         shares of Hughes Class B Common Stock constituting Excess
         Shares, any cash in lieu of fractional shares thereof, as the
         case may be.

                   Section 2.5.  Treatment of Raytheon Stock Options.
         Prior to the Effective Time, Hughes and Raytheon shall take all
         such actions as may be necessary to cause each unexpired and
         unexercised option under stock option plans of Raytheon in
         effect on the date hereof which has been granted to current or
         former directors, officers, employees, consultants or
         independent contractors of Raytheon or its subsidiaries or to
         any other persons by Raytheon (each, a "Raytheon Option") to be
         automatically converted at the Effective Time into an option (a
         "Hughes Exchange Option") to purchase that number of shares of
         Hughes Class B Common Stock equal to the number of shares of
         Raytheon Common Stock issuable immediately prior to the
         Effective Time upon exercise of the Raytheon Option (without
         regard to actual restrictions on exercisability), with an
         exercise price equal to the exercise price which existed under
         the corresponding Raytheon Option, and with other terms and
         conditions that are the same as the terms and conditions of
         such Raytheon Option immediately before the Effective Time
         (except for any changes in vesting rights or permitted time of
         exercise which result from the occurrence of the Merger).  In
         connection with the issuance of Hughes Exchange Options, Hughes
         shall (i) reserve for issuance the number of shares of Hughes
         Class B Common Stock that will become subject to Hughes
         Exchange Options pursuant to this Section 2.5, and (ii) from
         and after the Effective Time, upon exercise of Hughes Exchange
         Options, make available for issuance all shares of Hughes Class
         B Common Stock covered thereby, subject to the terms and
         conditions applicable thereto.


                                    ARTICLE 3

                     REPRESENTATIONS AND WARRANTIES OF HUGHES

                   In order to induce Raytheon to enter into this
         Agreement, Hughes hereby represents and warrants to Raytheon
         that the statements contained in this Article are true, correct
         and complete.  The parties hereto agree that representations
         and warranties of Hughes


                                       -9-<PAGE>







         set forth in this Article 3 have been prepared on a basis that
         reflects the consummation of the HEC Reorganization (as defined
         in the Hughes Distribution Agreement, the "HEC Reorganization")
         and accordingly, all references to Hughes exclude all
         businesses, assets or obligations of Hughes which will not be
         such following the consummation of the HEC Reorganization.

                   Section 3.1.  Organization and Standing.  Hughes and
         each of its significant subsidiaries is a corporation duly
         organized, validly existing and in good standing under the laws
         of the State of Delaware, with respect to Hughes, and under the
         laws of its state or other jurisdiction of incorporation, with
         respect to its significant subsidiaries, in each case with full
         power and authority (corporate and other) to own, lease, use
         and operate its properties and to conduct its business as and
         where owned, leased, used, operated and conducted.  Hughes and
         each of its significant subsidiaries is duly qualified to do
         business and in good standing in each jurisdiction in which the
         nature of the business conducted by it or the property it owns,
         leases or operates makes such qualification necessary, except
         where the failure to be so qualified or in good standing in
         such jurisdiction would not have a material adverse effect on
         Hughes.  Hughes is not in default in the performance,
         observance or fulfillment of any provision of its certificate
         of incorporation or by-laws, as amended.

                   Section 3.2.  Subsidiaries.  Hughes does not own,
         directly or indirectly, any equity or other ownership interest
         in any corporation, partnership, joint venture or other entity
         or enterprise, except as set forth in Section 3.2 to the
         disclosure schedule delivered by Hughes to Raytheon and dated
         as of the date hereof (the "Hughes Disclosure Schedule").
         Except as set forth in Section 3.2 to the Hughes Disclosure
         Schedule, Hughes is not subject to any obligation or
         requirement to provide funds to or make any investment (in the
         form of a loan, capital contribution or otherwise) in any such
         entity.  Except as set forth in Section 3.2 to the Hughes
         Disclosure Schedule, Hughes owns directly or indirectly each of
         the outstanding shares of capital stock (or other ownership
         interests having by their terms ordinary voting power to elect
         a majority of directors or others performing similar functions
         with respect to such significant subsidiary) of each of its
         significant subsidiaries.  Each of the outstanding shares of
         capital stock of each of Hughes' significant subsidiaries is
         duly authorized, validly issued, fully paid and nonassessable,
         and is owned, directly or indirectly, by Hughes free and clear
         of all liens, pledges, security interests, claims or other
         encumbrances.  Other than as set forth in Section 3.2 to the
         Hughes Disclosure Schedule, there are no outstanding
         subscriptions, options, warrants, puts, calls, agreements,
         understandings, claims or other commitments or rights of any
         type relating to the issuance, sale or transfer of any
         securities of any significant subsidiary of Hughes, nor are
         there outstanding any securities which are convertible into or
         exchangeable for any shares of capital stock of any significant
         subsidiary of Hughes; and no significant subsidiary of Hughes


                                      -10-<PAGE>







         has any obligation of any kind to issue any additional
         securities or to pay for securities of Hughes or any
         significant subsidiary of Hughes or any predecessor of any of
         the foregoing.

                   Section 3.3.  Corporate Power and Authority.  Hughes
         has all requisite corporate power and authority to enter into
         this Agreement and to consummate the transactions contemplated
         hereby.  The execution and delivery of this Agreement by Hughes
         and the consummation of the transactions contemplated hereby to
         be effected by Hughes have been duly authorized by all
         necessary corporate action on the part of Hughes.  This
         Agreement has been duly executed and delivered by Hughes, and
         constitutes the legal, valid and binding obligation of Hughes,
         enforceable against it in accordance with its terms.

                   Section 3.4.  Capitalization of Hughes.  (a)  As of
         September 30, 1996, Hughes' authorized capital stock consisted
         solely of 75,000 shares of common stock, without par value, all
         of which were issued and outstanding.  Each outstanding share
         of Hughes capital stock is duly authorized and validly issued,
         fully paid and nonassessable, and has not been issued in
         violation of any preemptive or similar rights and is owned
         indirectly by GM free and clear of all liens, pledges, security
         interests, claims or other encumbrances.  Each share of Hughes
         Class B Common Stock to be issued in connection with the Merger
         will be duly authorized and validly issued, fully paid and
         nonassessable and will not be issued in violation of any
         preemptive or similar rights.  Hughes has no authorized or
         outstanding bonds, debentures, notes or other obligations or
         securities, the holders of which have the right to vote with
         the stockholders of Hughes on any matter.

                   (b)  Immediately prior to the Effective Time, but
         after giving effect to the GM Transactions, Hughes will have
         (i) 102,630,503 shares of Class A Common Stock outstanding,
         (ii) no shares of Class A Common Stock reserved for issuance
         upon the exercise of outstanding options, warrants and
         convertible securities, (iii) not more than 4,150,000 shares of
         Class B Common Stock reserved for issuance upon the exercise of
         outstanding options (plus (x) up to 1,000,000 additional shares
         of Class B Common Stock which may be reserved for issuance in
         respect of options granted after July 1, 1997 in accordance
         with Section 5(c) of Schedule EM of the Separation Agreement
         and plus (y) such additional shares of Class B Common Stock
         which may be reserved for issuance in respect of options
         associated with any corporate employees of Hughes or its
         affiliates which Hughes and Raytheon agree may become or remain
         employees of the Surviving Corporation after the Merger), (iv)
         no shares of any other class of capital stock outstanding, and
         (v) except as set forth in the foregoing clause (iii) or as
         otherwise contemplated by this Agreement, no shares of Class A
         Common Stock, Class B Common Stock or any other class of
         capital stock subject in any event to issuance upon the
         exercise, conversion or exchange of any other securities or
         pursuant to any contractual or other right, option, warrant or
         agreement.

                   (c)  Other than as contemplated by the Merger or as
         set forth in Section 3.4 to the Hughes Disclosure Schedule,
         there are no outstanding subscriptions, options, warrants,
         puts, calls, agreements, understandings, claims or other
         commitments or rights of any type relating to the issuance,
         sale or transfer of any securities of Hughes, nor are there
         outstanding any securities which are convertible into or
         exchangeable for any shares of capital stock of Hughes; and
         Hughes has no obligation of any kind to issue any additional
         securities or to pay for securities of Hughes or any
         predecessor or affiliate.  The issuance and sale of all of the
         shares of capital stock described in this Section 3.4 have been
         in compliance with federal and state securities laws.  Except
         as set forth in Section 3.4 to the Hughes Disclosure Schedule,
         Hughes has not agreed to register any securities under the
         Securities Act of 1933, as amended (together with rules and
         regulation thereunder, the "Securities Act"), or under any
         state securities law or granted registration rights with
         respect to any securities of Hughes to any person or entity.

                   Section 3.5.  Conflicts, Consents and Approvals.
         Neither the execution and delivery of this Agreement by Hughes
         nor the consummation of the transactions contemplated hereby
         will:

                   (a)  conflict with, or result in a breach of any
         provision of the certificate of incorporation or by-laws of
         Hughes or its significant subsidiaries;

                   (b)  violate, or conflict with, or result in a breach
         of any provision of, or constitute a default (or an event
         which, with the giving of notice, the passage of time or
         otherwise, would constitute a default) under, or entitle any
         party (with the giving of notice, the passage of time or
         otherwise) to terminate, accelerate, modify or call a default
         under, or result in the creation of any lien, security
         interest, charge or encumbrance upon any of the properties or
         assets of Hughes or any of its significant subsidiaries under,
         any of the terms, conditions or provisions of any note, bond,
         mortgage, indenture, deed of trust, intellectual property or
         other license, contract, undertaking, agreement, lease or other
         instrument or obligation to which Hughes or any of its
         significant subsidiaries is a party;

                   (c)  violate any order, writ, injunction, decree,
         statute, rule or regulation applicable to Hughes or any of its
         significant subsidiaries or any of their respective properties
         or assets; or

                   (d)  except as contemplated by the Hughes
         Distribution Agreement, require any action or consent or
         approval of, or review by, or registration or filing by Hughes
         or any of its affiliates with, any third party or any court,
         arbitral tribunal, administrative agency or commission or other
         governmental or regulatory body, agency, instrumentality or au-

         authorization for listing of the shares of Hughes Class A
         Common Stock and Hughes Class B Common Stock to be issued in
         the Merger on the NYSE, subject to official notice of issuance,
         (ii) actions required by the Hart-Scott-Rodino Antitrust
         Improvements Act of 1976, as amended, and the rules and

         comparable laws of foreign jurisdictions, (iii) registrations
         or other actions required under federal and state securities
         laws as are contemplated by this Agreement, and (iv) as set
         forth in Section 3.5 to the Hughes Disclosure Schedule;

         except in the case of (b), (c) and (d) for any of the foregoing
         that, individually or in the aggregate, would neither have a
         material adverse effect on Hughes nor materially delay or
         adversely impact Hughes' ability to consummate the transactions
         contemplated hereby and by the other Transaction Agreements (as
         defined in the GM Implementation Agreement, the "Transaction
         Agreements").

                   Section 3.6.  Hughes Financial Statements.  (a)
         Included in the Hughes Disclosure Schedule are (i) pro forma
         unaudited consolidated balance sheets as of December 31, 1995
         and 1994, and pro forma unaudited consolidated statements of
         income and cash flows for the two years ended December 31, 1995
         and 1994, for Hughes and its subsidiaries (such financial
         statements, the "Hughes Statements" and the balance sheet as of
         December 31, 1995 included therein, the "Hughes Balance
         Sheet"), and (ii) an unaudited pro forma consolidated balance
         sheet and statement of income and cash flows at and for the
         nine months ended September 30, 1996 for Hughes and its
         subsidiaries (the "Hughes Interim Statements").  The Hughes
         Statements and the Hughes Interim Statements have been prepared
         on a basis that gives effect to the consummation of the HEC
         Reorganization, except to the extent disclosed in the notes
         thereto.  The Hughes Balance Sheet (including any related notes
         and schedules) and the consolidated balance sheet included in
         the Hughes Interim Statements fairly present in all material
         respects the consolidated financial position of Hughes and its
         subsidiaries, after giving effect to the consummation of the
         HEC Reorganization, as of their respective dates, and each of
         the consolidated statements of income and cash flows included
         in the Hughes Statements and the Hughes Interim Statements
         fairly presents in all material respects the consolidated
         results of operations and cash flows, as the case may be, of
         Hughes and its subsidiaries, after giving effect to the
         consummation of the HEC Reorganization, for the periods set
         forth therein, in each case in accordance with generally
         accepted accounting principles ("GAAP") consistently applied
         except as disclosed in the Basis of Presentation note thereto
         and except that footnotes to the Hughes Statements and the
         Hughes Interim Statements required by GAAP are omitted.

                   (b)  Proper accounting controls are, and since
         January 1, 1994, have been, in place to ensure that no portion
         of any international sales representative commission or
         contingent fee payment is included, directly or indirectly, in
         the contract price of any sale to the United States Government
         pursuant to the Foreign Military Sales ("FMS") program, or any
         sale to a foreign government financed in whole or in part with
         funding from the U.S. Foreign Military Finance ("FMF") program,
         except as permitted thereunder and except where there is no
         reasonable likelihood that the failure to have in place such
         controls would give rise to any unreserved loss, cost or
         expense in excess of $10 million individually or, when
         aggregated with the aggregate of those items excepted from the
         representations set forth in clause (c) below and in Sections
         3.9 and 3.13, $100 million.

                   (c)  All payments to international sales
         representatives since January 1, 1994, including commission and
         contingent fee payments to international sales representatives
         on FMS and FMF contracts, (i) have been accurately reported on
         Hughes' books and records, and (ii) have been made consistent
         with all applicable United States and foreign laws and
         regulations, except where there is no reasonable likelihood
         that the failure to accurately report or to be consistent with
         applicable law would give rise to any unreserved loss, cost or
         expense in excess of $10 million individually or, when
         aggregated with the aggregate of those items excepted from the
         representations set forth in clause (b) above and in Sections
         3.9 and 3.13, $100 million.

                   Section 3.7.  Registration Statement.  None of the
         information provided by or on behalf of Hughes for inclusion in
         the registration statement on Form S-4, as supplemented or
         amended from time to time (the "Registration Statement"),
         including the prospectus, as supplemented or amended from time
         to time, relating to the shares of Hughes Class B Common Stock
         to be issued in the Merger (the "Prospectus"), at the time it
         becomes effective or, in the case of Raytheon's proxy statement
         or consent solicitation with respect to the Merger, as
         supplemented or amended from time to time (the "Proxy
         Statement"), at the date of mailing or at the date of voting or
         consent and approval with respect thereto, will contain any
         untrue statement of a material fact or omit to state any
         material fact required to be stated therein or necessary in
         order to make the statements therein, in light of the cir-
         cumstances under which they are made, not misleading.  The
         Registration Statement, except for such portions thereof that
         relate only to Raytheon, will comply as to form in all material
         respects with the provisions of the Securities Act and the
         Securities Exchange Act of 1934, as amended (together with the
         rules and regulations thereunder, the "Exchange Act").

                   Section 3.8.  Compliance with Law.  Hughes and its
         subsidiaries are in compliance with, and at all times since
         December 31, 1994 have been in compliance with, all applicable
         laws, statutes, orders, rules, regulations, policies or
         guidelines promulgated, or


                                      -14-<PAGE>







         judgments, decisions or orders entered by any Governmental
         Authority (collectively, "Applicable Law") relating to them or
         their businesses or properties, including, without limitation,
         the Truth-In-Negotiations Act, the Procurement Integrity Act,
         the Foreign Corrupt Practices Act and the Cost Accounting
         Standards, except where the failure to be in compliance
         therewith would not have a material adverse effect on Hughes.

                   Section 3.9.  Litigation.  Except as set forth in
         Section 3.9 to the Hughes Disclosure Schedule, there is no
         suit, claim, action, proceeding or investigation, whether
         civil, criminal or administrative in nature (an "Action"),
         pending or, to the knowledge of Hughes threatened against
         Hughes or any of its subsidiaries, nor are there any facts
         known to Hughes which would support an Action, which has any
         reasonable likelihood of resulting in unreserved liability to
         Hughes or its subsidiaries in excess of $10 million
         individually or, when aggregated with the aggregate of those
         items excepted from the representations set forth in Sections
         3.6(b) and (c) and Section 3.13, $100 million or a material
         adverse effect on the ability of Hughes to consummate the
         transactions contemplated hereby.  Hughes is not subject to any
         outstanding order, writ, injunction or decree which,
         individually or in the aggregate, insofar as can be reasonably
         foreseen, could have a material adverse effect on Hughes or on
         its ability to consummate the transactions contemplated hereby.
         Except as set forth in Section 3.9 to the Hughes Disclosure
         Schedule, since December 31, 1994, neither Hughes nor any of
         its significant subsidiaries has been subject to any
         outstanding order, writ, injunction or decree relating to its
         method of doing business or its relationship with past,
         existing or future users or purchasers of any goods or services
         of Hughes or any such subsidiaries.

                   Section 3.10.  Taxes.  Hughes and its subsidiaries
         have filed (or there have been duly filed on their behalf) all
         federal and material state, local and foreign income,
         franchise, excise, real and personal property and other tax
         returns and reports (including, but not limited to, those filed
         on a consolidated, combined or unitary basis) required to have
         been filed by them prior to the date hereof (taking into
         account extensions).  All of the foregoing returns and reports,
         to the extent they relate to the income, assets or business of
         Hughes or its subsidiaries, are true and correct in all
         material respects, and Hughes and its subsidiaries have paid
         (or there have been paid on their behalf), or adequate
         provision has been made in the financial statements of Hughes
         included in the Hughes Disclosure Schedule for all taxes
         payable in respect of all periods ending on or prior to
         September 30, 1996. None of Hughes or any of its subsidiaries
         (i) will have any liability for any taxes in excess of the
         amounts so paid or reserves so established, (ii) is delinquent
         in the payment of any tax, assessment or governmental charge or
         (iii) has requested any extension of time within which to file
         any returns in respect of any fiscal year which have not since
         been filed, except, in each case, where such liability,
         delinquency or failure to request such an extension would not


                                      -15-<PAGE>







         have a material adverse effect on Hughes.  No deficiencies for
         any tax, assessment or governmental charge have been proposed
         in writing, asserted or assessed (tentatively or definitely),
         in each case, by any taxing authority, against Hughes or any of
         its subsidiaries for which there are not adequate reserves.
         Except as set forth in Section 3.10 to the Hughes Disclosure
         Schedule, none of Hughes or any of its subsidiaries (or any
         consolidated, combined or unitary group of which any such
         corporation is a member) is the subject of any tax audit which
         could reasonably be expected to have a material adverse effect
         on Hughes. As of the date of this Agreement, there are no
         pending requests for waivers of the time to assess any such
         tax, other than those made in the ordinary course and for which
         payment has been made or there are adequate reserves.  The
         consolidated federal income tax returns of GM through the
         fiscal year ending December 31, 1990 have been audited by the
         Internal Revenue Service.  For the purposes of this Agreement,
         the term "tax" shall include all federal, state, local and
         foreign taxes including interest and penalties thereon.

                   Section 3.11.  Absence of Certain Changes.  (a)
         Except as set forth in Section 3.11 to the Hughes Disclosure
         Schedule and except as contemplated by the GM Implementation
         Agreement, since September 30, 1996, the businesses of Hughes
         and its subsidiaries have been conducted in the ordinary
         course, consistent with past practice, and there has been no
         (i) material adverse change in the assets, liabilities, results
         of operations, business or financial condition of Hughes and
         its subsidiaries taken as a whole or (ii) material adverse
         effect on the ability of Hughes to consummate the transactions
         contemplated hereby.

                   (b)  Except (i) as set forth in Schedule 3.11 to the
         Hughes Disclosure Schedule, (ii) for the Separation Agreements
         (as defined in the Hughes Distribution Agreement, the
         "Separation Agreement"), and (iii) pursuant to customary
         accounting practices relating to Government Contracts (A)
         neither Hughes nor any of its subsidiaries has entered into any
         agreement material to Hughes and its subsidiaries, taken as a
         whole, with GM or any affiliate of GM on terms that are not as
         favorable, in all material respects, to terms that would be
         obtainable in comparable agreements with unrelated third
         parties, and (B) from the date hereof to the Effective Time
         Hughes will not enter into any such agreement, excluding for
         all purposes of this Section 3.11 any such agreement which will
         not continue in force from and after the Effective Time.

                   (c)  Except (i) as set forth in Schedule 3.11 to the
         Hughes Disclosure Schedule and (ii) for the Separation
         Agreement, since September 30, 1996, neither Hughes nor any of
         its subsidiaries has taken any action referred to in clauses
         (i) through (xiii) of Section 5.2(a) hereof.


                                      -16-<PAGE>







                   Section 3.12.  Undisclosed Liabilities.  Except as
         and to the extent disclosed or reserved against on the Hughes
         Interim Statements, neither Hughes nor any of its subsidiaries
         has any liabilities or obligations of any nature, whether known
         or unknown, absolute, accrued, contingent or otherwise, and
         whether due or to become due, except (i) as set forth in
         Section 3.12 to the Hughes Disclosure Schedule, (ii) as
         incurred after the date of the Hughes Interim Statements in the
         ordinary course of business consistent with prior practice, or
         (iii) for liabilities and obligations which are not,
         individually or in the aggregate, material to Hughes and its
         subsidiaries, taken as a whole.

                   Section 3.13.  Environmental Matters.  (a)  As used
         herein, the term "Environmental Laws" means all applicable
         federal, state, local or foreign laws relating to pollution or
         protection of human health or the environment (including
         ambient air, surface water, groundwater, land surface or
         subsurface strata), including laws relating to emissions,
         discharges, releases or threatened releases of chemicals,
         pollutants, contaminants, or industrial, toxic or hazardous
         substances or wastes (collectively, "Hazardous Materials") into
         the environment, or otherwise relating to the manufacture,
         processing, distribution, use, treatment, storage, disposal,
         transport or handling of Hazardous Materials, as well as all
         applicable authorizations, codes, decrees, demands or demand
         letters, injunctions, judgments, licenses, notice or notice
         letters, orders, permits, plans or regulations issued, entered,
         promulgated or approved thereunder.

                   (b)  There are, with respect to Hughes and its
         subsidiaries, and to Hughes' knowledge with respect to its and
         their predecessors, no past or present material violations of
         Environmental Laws, releases of any material into the
         environment, actions, activities, circumstances, conditions,
         events, incidents, or contractual obligations which may give
         rise to any liability under any applicable Environmental Laws
         and none of Hughes or its subsidiaries has received any notice
         with respect to any of the foregoing, nor is any Action pending
         or to Hughes' knowledge threatened in connection with any of
         the foregoing;

                   (c)  Hughes is in material compliance with all
         applicable Environmental Laws;

                   (d)  Hughes has all valid permits required under
         Environmental Laws for the operation of its business as
         presently conducted;

         except, in the case of (b), (c) and (d) for any of the
         foregoing matters that would not reasonably be expected to
         result in Hughes or its subsidiaries incurring unreserved
         losses, costs or expenses in excess of $10 million individually
         or, when aggregated with the aggregate of those items excepted
         from the representations set forth in Sections 3.6(b) and (c)


                                      -17-<PAGE>







         and Section 3.9, $100 million, and except as is set forth in
         Section 3.9 or 3.13 to the Hughes Disclosure Schedule.

                   Section 3.14.  Employee Benefits.  (a)  The plans,
         contracts or arrangements described in subsections 3, 4, 5, 6
         and 7 of Schedule EM to the Separation Agreement include
         (i) all "employee benefit plans", as defined in Section 3(3) of
         ERISA, which Hughes and/or its subsidiaries maintain (the
         "Hughes Employee Benefit Plans") and (ii) all material
         employment agreements, and all material bonus and other
         incentive compensation, deferred compensation, disability,
         severance, stock award, stock option or stock purchase
         agreements, collective bargaining agreements, workers'
         compensation, policies and arrangements with respect to the
         employment and termination of employment of any officer,
         director or other employee whose principal place of employment
         is in the United States under which Hughes or its subsidiaries
         could have any liability (the "Hughes Employee Arrangements").  

                   (b)  With respect to each Hughes Employee Benefit
         Plan and Hughes Employee Arrangement, a complete and correct
         copy of each of the following documents has been provided or
         made available to Raytheon: (i) the most recent plan document
         or agreement, and all amendments thereto and all related trust
         documents; (ii) the most recent summary plan description, and
         all related summaries of material modifications; and (iii) the
         most recent actuarial and financial reports.

                   (c)  None of the Hughes Employee Benefit Plans is
         subject to Section 4063, 4064 or 4202 of ERISA.

                   (d)  With respect to each Hughes Employee Benefit
         Plan that is subject to Title IV or Section 302 of ERISA or
         Section 412 or 4971 of the Code (other than a Multiemployer
         Plan, as defined below), except as would not have a material
         adverse effect on Hughes:  (i) there does not exist any
         accumulated funding deficiency within the meaning of Section
         412 of the Code or Section 302 of ERISA, whether or not waived;
         (ii) except for the Hughes Employee Benefit Plans disclosed in
         Section 3.14(d) of the Hughes Disclosure Schedule, the fair
         market value of the assets of such Plan equals or exceeds the
         actuarial present value of all accrued benefits under the Plan
         (whether or not vested), on a termination basis; (iii) other
         than the consummation of the transactions contemplated by this
         Agreement, no reportable event within the meaning of Section
         4043(c) of ERISA has occurred; and (iv) all premiums to the
         Pension Benefit Guaranty Corporation have been paid in full and
         there are no outstanding penalties or interest assessments.
         With respect to each Hughes Employee Benefit Plan which is a
         Multiemployer Plan, except as would not have a material adverse
         effect on Hughes:  (i) no Withdrawal Liability (as defined
         below) exists that has not been satisfied in full; (ii) if
         Hughes or any of its subsidiaries were to experience a
         withdrawal or


                                      -18-<PAGE>







         partial withdrawal from such Plan, no Withdrawal Liability
         would be incurred; and (iii) neither Hughes nor any of its
         subsidiaries has received any notification, nor has any reason
         to believe, that any such Plan is in reorganization, has been
         terminated, or may reasonably be expected to be in
         reorganization or to be terminated.  A "Multiemployer Plan"
         means any "multiemployer plan" within the meaning of Section
         4001(a)(3) of ERISA.  "Withdrawal Liability" means liability to
         a Multiemployer Plan as a result of a complete or partial
         withdrawal from such Multiemployer Plan, as those terms are
         defined in Part I of Subtitle E of Title IV of ERISA.

                   (e)  All contributions required to have been made by
         Hughes or its subsidiaries under any Hughes Employee Benefit
         Plan or any Applicable Law to any trusts established thereunder
         or in connection therewith have been made by the due date
         therefor (including any valid extensions), except where any
         failure to contribute would not, individually or in the
         aggregate, have a material adverse effect on Hughes.

                   (f)  The Hughes Employee Benefit Plans and Hughes
         Employee Arrangements have been maintained, in all material
         respects, in accordance with their terms and Applicable Law,
         including but not limited to the filing of applicable reports,
         documents and notices regarding any Hughes Employee Benefit
         Plans with the Secretary of Labor and the Secretary of the
         Treasury, or the furnishing of such documents to participants
         in the Hughes Employee Benefit Plans, except where any failure
         to comply would not, individually or in the aggregate, have a
         material adverse effect on Hughes.

                   (g)  With respect to each Hughes Employee Benefit
         Plan that is intended to be a "qualified plan" within the
         meaning of Section 401(a) of the Code (a "Qualified Plan"),
         either the Internal Revenue Service has issued a favorable
         determination letter that has not been revoked, or an
         application for a favorable determination letter was timely
         submitted to the Internal Revenue Service for which no final
         action has been taken by the Internal Revenue Service, and
         there are no existing circumstances nor any events that have
         occurred that could adversely affect the qualified status of
         any Qualified Plan or the related trust, except to the extent
         such circumstances or events can be cured without a material
         adverse effect on Hughes.  Each Hughes Employee Benefit Plan
         which is intended to meet the requirements of Section 501(c)(9)
         of the Code meets such requirements and provides no
         disqualified benefits (as such term is defined in Section
         4976(b) of the Code), except as would not have a material
         adverse effect on Hughes.

                   (h)  Section 3.14(h) of the Hughes Disclosure
         Schedule (i) identifies each Hughes Employee Benefit Plan and
         each Hughes Employee Arrangement that is part of a plan or
         arrangement that is to be split pursuant to Schedule EM to the
         Separation Agreement,


                                      -19-<PAGE>







         (ii) identifies any funding vehicle associated therewith and
         (iii) states whether there are any employee contributions made
         with respect thereto.

                   Section 3.15.  Brokerage and Finder's Fees.  Except
         for obligations to Goldman, Sachs & Co., Merrill Lynch, Pierce,
         Fenner & Smith Incorporated and Salomon Brothers Inc, neither
         Hughes nor any of its affiliates, stockholders, directors,
         officers or employees has incurred or will incur on behalf of
         Hughes or any affiliate of Hughes, any brokerage, finder's or
         similar fee in connection with the transactions contemplated by
         this Agreement.  Other than with respect to the fee of Goldman,
         Sachs & Co., which may be paid by Hughes, no such fee will be
         charged against or payable by Hughes or any subsidiary thereof,
         and if the fee of Goldman, Sachs & Co. is payable by Hughes
         after the Effective Time, it will be reflected as a liability
         on the Closing Date Balance Sheet (as defined in the Separation
         Agreement).  A copy of all agreements relating to any such fee
         payable by Hughes or any subsidiary thereof to Goldman, Sachs &
         Co. has (or upon request will be) delivered to Raytheon.

                   Section 3.16.  Opinion of Financial Advisor.  The
         Boards of Directors of GM, HEC and Hughes have received the
         written opinion of Goldman, Sachs & Co., their financial
         advisor, to the effect that, as of January 16, 1997, the
         Aggregate Consideration (as defined therein) is fair to the GM
         Group (as defined therein) as a whole.  Hughes has heretofore
         provided a copy of such opinion to Raytheon and such opinion
         has not been withdrawn, revoked or modified.

                   Section 3.17.  Board and Stockholder Approval.  The
         Board of Directors of Hughes, at a meeting duly called and
         held, has, by unanimous vote of the directors then in office
         determined that this Agreement and the transactions
         contemplated hereby are fair to and in the best interests of
         Hughes and its stockholder.  Hughes Electronics Corporation
         ("HEC"), in its capacity as sole stockholder of Hughes, has,
         acting by written consent, determined that this Agreement and
         the transactions contemplated hereby are fair to and in the
         best interests of Hughes and its stockholder, and adopted and
         approved this Agreement and the transactions contemplated
         hereby.  No other vote of the holders of any class or series of
         Hughes capital stock or indebtedness is necessary to approve
         and adopt this Agreement and the transactions contemplated
         hereby.

                   Section 3.18.  DGCL Section 203 and State Takeover
         Laws.  Prior to the date hereof, the Board of Directors of
         Hughes has taken all action necessary to exempt under or make
         not subject to (x) Section 203 of the DGCL and (y) to its
         knowledge, any other state takeover law or state law that
         purports to limit or restrict business combinations or the
         ability


                                      -20-<PAGE>







         to acquire or vote shares (i) the execution of this Agreement,
         (ii) the Merger and (iii) the transactions contemplated hereby
         and by the Hughes Distribution Agreement.

                   Section 3.19.  Permits.  Hughes and its subsidiaries
         have in effect all federal, state, local and foreign
         governmental approvals, authorizations, certificates, filings,
         franchises, licenses, notices, permits and rights ("Permits")
         necessary for them to own, lease and operate their properties
         and assets and to carry on their business as now conducted or
         as presently contemplated to be conducted, and there has
         occurred no default under any such Permit, except for the
         absence of Permits and for defaults under Permits which absence
         or defaults, individually or in the aggregate, would not have a
         material adverse effect on Hughes.

                   Section 3.20.  Restrictive Agreements.  Except as set
         forth in Section 3.20 of the Hughes Disclosure Schedule, Hughes
         and its subsidiaries will not be parties to or bound by any
         agreement, contract, policy, license, Permit, document,
         instrument, arrangement or commitment that materially limits,
         after the Effective Time, the ability of Hughes or any of its
         subsidiaries to compete in any line of business or with any
         person or in any geographic area or which would so limit, after
         the Effective Time, the ability of the Surviving Corporation or
         any subsidiary thereof.

                   Section 3.21.  Real Estate.  Each of Hughes and its
         subsidiaries (i) has good and marketable title to its owned
         real properties and (ii) has valid and subsisting leasehold
         interests in its leased real properties, in each case free and
         clear of any liens or encumbrances of whatsoever nature, other
         than liens and encumbrances which would not reasonably be
         expected to have a material adverse effect on Hughes.  The real
         property leased or owned by Hughes or any of its subsidiaries
         (including, without limitation, all buildings, structures,
         improvements and fixtures located thereon, thereunder,
         thereover or therein, and all appurtenances thereto and other
         aspects thereof):  (1) is in good operating condition and
         repair and is structurally sound and free of defects, with no
         material alterations or repairs being required thereto under
         applicable law or insurance company requirements; and (2) is
         otherwise suitable, sufficient, adequate and appropriate in all
         respects (whether physical, structural, operational, legal,
         practical or otherwise) for its current use, operation and
         occupancy, except, in each such case, to the extent that
         failure to meet such standards would not reasonably be expected
         to have a material adverse effect on Hughes.  Except as set
         forth in Section 3.21 of the Hughes Disclosure Schedule, no
         material real property owned or leased by Hughes or any of its
         subsidiaries is subject to any sales contracts, option, right
         of first refusal or similar agreement or arrangement with any
         third party.


                                      -21-<PAGE>







                   Section 3.22.  Employees.  (a)  There is no labor
         strike or work stoppage pending or, to the knowledge of Hughes,
         threatened against Hughes or any of its subsidiaries that,
         individually or in the aggregate, has had or would reasonably
         be expected to have a material adverse effect on Hughes.
         Except as set forth in Section 3.22 of the Hughes Disclosure
         Schedule, neither Hughes nor any of its subsidiaries is a party
         to any collective bargaining agreement, nor has Hughes
         received, within the past 12 months, any demand or request for
         recognition by a labor organization purporting to represent any
         employees of Hughes or its subsidiaries.

                   (b)  Except as set forth in Section 3.22 of the
         Hughes Disclosure Schedule, neither Hughes nor any of its
         subsidiaries is a party to any severance or change-in-control
         plan or agreement which could entitle any employee of Hughes or
         any such subsidiary to payments as a result of the consummation
         of the transactions contemplated by this Agreement.

                   Section 3.23.  Certain Retirement Assets.  (a)  The
         aggregate fair market value of the assets of the HEC Bargaining
         and Nonbargaining Retirement Plans as of November 30, 1996 was
         not less than $7,000,000,000.  The actuarial accrued liability
         for such plans as of December 1, 1995 under government cost
         accounting standards was $4,677,000,000 as calculated and
         disclosed in the Actuarial Reports for Fiscal Year ending
         December 31, 1996 and Plan Year beginning December 1, 1995 as
         prepared by Towers, Perrin.  To the best knowledge of Hughes,
         as of December 1, 1996 there has been no material increase in
         such liabilities, other than those arising as a result of
         benefit accruals, terminations, retirements, salary increases
         and growth due to interest, all of which have occurred in the
         ordinary course of business. 

                   (b)  To the best knowledge of Hughes, the share of
         the assets of the HEC Retirement Plan allocable to the defense
         business under government cost accounting standards (i.e., the
         Defense Business Fraction, as defined in Schedule EM to the
         Separation Agreement as determined as of November 30, 1996) is
         not less than 70% as of November 30, 1996.


                                    ARTICLE 4

                    REPRESENTATIONS AND WARRANTIES OF RAYTHEON

                   In order to induce Hughes to enter into this
         Agreement, Raytheon hereby represents and warrants to Hughes
         that the statements contained in this Article are true, correct
         and complete.


                                      -22-<PAGE>







                   Section 4.1.  Organization and Standing.  Raytheon
         and each of its significant subsidiaries is a corporation duly
         organized, validly existing and in good standing under the laws
         of the State of Delaware, with respect to Raytheon, and under
         the laws of its state or other jurisdiction of incorporation,
         with respect to its significant subsidiaries, in each case with
         full power and authority (corporate and other) to own, lease,
         use and operate its properties and to conduct its business as
         and where owned, leased, used, operated and conducted.
         Raytheon and each of its significant subsidiaries is duly
         qualified to do business and in good standing in each
         jurisdiction in which the nature of the business conducted by
         it or the property it owns, leases or operates makes such
         qualification necessary, except where the failure to be so
         qualified or in good standing in such jurisdiction would not
         have a material adverse effect on Raytheon.  Raytheon is not in
         default in the performance, observance or fulfillment of any
         provision of its certificate of incorporation, as amended or
         by-laws, as amended and restated.

                   Section 4.2.  Subsidiaries.  Raytheon does not own,
         directly or indirectly, any equity or other ownership interest
         in any corporation, partnership, joint venture or other entity
         or enterprise, except as set forth in Section 4.2 to the
         disclosure schedule delivered by Raytheon to Hughes and dated
         as of the date hereof (the "Raytheon Disclosure Schedule").
         Except as set forth in Section 4.2 to the Raytheon Disclosure
         Schedule, Raytheon is not subject to any obligation or
         requirement to provide funds to or make any investment (in the
         form of a loan, capital contribution or otherwise) in any such
         entity.  Except as set forth in Section 4.2 to the Raytheon
         Disclosure Schedule, Raytheon owns directly or indirectly each
         of the outstanding shares of capital stock (or other ownership
         interests having by their terms ordinary voting power to elect
         a majority of directors or others performing similar functions
         with respect to such significant subsidiary) of each of its
         significant subsidiaries.  Each of the outstanding shares of
         capital stock of each of Raytheon's significant subsidiaries is
         duly authorized, validly issued, fully paid and nonassessable,
         and is owned, directly or indirectly, by Raytheon free and
         clear of all liens, pledges, security interests, claims or
         other encumbrances.  Other than as set forth in Section 4.2 to
         the Raytheon Disclosure Schedule, there are no outstanding
         subscriptions, options, warrants, puts, calls, agreements,
         understandings, claims or other commitments or rights of any
         type relating to the issuance, sale or transfer of any
         securities of any significant subsidiary of Raytheon, nor are
         there outstanding any securities which are convertible into or
         exchangeable for any shares of capital stock of any significant
         subsidiary of Raytheon; and no significant subsidiary of
         Raytheon has any obligation of any kind to issue any additional
         securities or to pay for securities of Raytheon or any
         significant subsidiary of Raytheon or any predecessor of any of
         the foregoing.

                   Section 4.3.  Corporate Power and Authority.
         Raytheon has all requisite corporate power and authority to
         enter into this Agreement and, subject to the approval of
         Raytheon Stockholders, Raytheon has all requisite corporate
         power and authority to consummate the transactions contemplated
         hereby.  The execution and delivery of this Agreement by
         Raytheon and the consummation of the transactions contemplated
         hereby to be effected by Raytheon have been duly authorized by
         all necessary corporate action on the part of Raytheon, subject
         to the approval of Raytheon Stockholders.  This Agreement has
         been duly executed and delivered by Raytheon, and constitutes
         the legal, valid and binding obligation of Raytheon,
         enforceable against it in accordance with its terms.

                   Section 4.4.  Capitalization of Raytheon.  (a)  As of
         December 31, 1996, Raytheon's authorized capital stock
         consisted solely of (x) 400,000,000 shares of Raytheon Common
         Stock, of which (i) 236,250,167 shares were issued and
         outstanding, (ii) 69,123,796 shares of Raytheon Common Stock
         were held in the treasury of Raytheon and (iii) 12,570,360
         shares were reserved for issuance upon the exercise or
         conversion of outstanding options  granted by Raytheon with an
         average weighted exercise price as set forth in Section 4.4 of
         the Raytheon Disclosure Schedule and (y) 3,000,000 shares of
         preferred stock, without par value, none of which were issued
         and outstanding or reserved for issuance.  Each outstanding
         share of Raytheon capital stock is duly authorized and validly
         issued, fully paid and nonassessable, and has not been issued
         in violation of any preemptive or similar rights.  Raytheon has
         no authorized or outstanding bonds, debentures, notes or other
         obligations or securities, the holders of which have the right
         to vote with the stockholders of Raytheon on any matter.

                   (b)  Other than as contemplated by the Merger or as
         set forth in Section 4.4 to the Raytheon Disclosure Schedule,
         there are no outstanding subscriptions, options, warrants,
         puts, calls, agreements, understandings, claims or other
         commitments or rights of any type relating to the issuance,
         sale or transfer of any securities of Raytheon, nor are there
         outstanding any securities which are convertible into or
         exchangeable for any shares of capital stock of Raytheon; and
         Raytheon has no obligation of any kind to issue any additional
         securities or to pay for securities of Raytheon or any
         predecessor or affiliate.  The issuance and sale of all of the
         shares of capital stock described in this Section 4.4 have been
         in compliance with federal and state securities laws.  The
         Raytheon Disclosure Schedule accurately sets forth the number
         of shares of Raytheon Common Stock issuable upon exercise of
         Raytheon Options, and the average exercise prices with respect
         thereto, along with a list of the options held by each
         corporate officer of Raytheon.  Except as set forth in Section
         4.4 to the Raytheon Disclosure Schedule, Raytheon has not
         agreed to register any securities under the Securities Act or
         under any state securities law or granted registration rights
         with respect to any securities of Raytheon to any person or
         entity.

                   Section 4.5.  Conflicts, Consents and Approvals.
         Neither the execution and delivery of this Agreement by
         Raytheon nor the consummation of the transactions contemplated
         hereby will:

                   (a)  conflict with, or result in a breach of any
         provision of the certificate of incorporation or by-laws of
         Raytheon or its significant subsidiaries;

                   (b)  violate, or conflict with, or result in a breach
         of any provision of, or constitute a default (or an event
         which, with the giving of notice, the passage of time or
         otherwise, would constitute a default) under, or entitle any
         party (with the giving of notice, the passage of time or
         otherwise) to terminate, accelerate, modify or call a default
         under, or result in the creation of any lien, security
         interest, charge or encumbrance upon any of the properties or
         assets of Raytheon or any of its significant subsidiaries
         under, any of the terms, conditions or provisions of any note,
         bond, mortgage, indenture, deed of trust, intellectual property
         or other license, contract, undertaking, agreement, lease or
         other instrument or obligation to which Raytheon or any of its
         significant subsidiaries is a party;

                   (c)  violate any order, writ, injunction, decree,
         statute, rule or regulation applicable to Raytheon or any of
         its significant subsidiaries or any of their respective
         properties or assets; or

                   (d)  require any action or consent or approval of, or
         review by, or registration or filing by Raytheon or any of its
         affiliates with, any third party or any Governmental Authority,
         other than, (i) authorization of the Merger and the
         transactions contemplated hereby by Raytheon Stockholders, (ii)
         actions required by the HSR Act and any comparable laws of
         foreign jurisdictions, (iii) registrations or other actions
         required under federal and state securities laws as are
         contemplated by this Agreement and (iv) as set forth in Section
         4.5 to the Raytheon Disclosure Schedule;

         except in the case of (b), (c) and (d) for any of the foregoing
         that, individually or in the aggregate, would neither have a
         material adverse effect on Raytheon nor materially delay or
         adversely impact Raytheon's ability to consummate the
         transactions contemplated hereby.

                   Section 4.6.  Raytheon SEC Documents.  (a)  Raytheon
         has timely filed with the Securities and Exchange Commission
         (the "Commission") all forms, reports, schedules, statements
         and other documents required to be filed by it since December
         31, 1994 under the Exchange Act or the Securities Act (such
         documents, as supplemented and amended since the time of
         filing, collectively, the "Raytheon SEC Documents").  The
         Raytheon SEC Documents, including any financial statements or
         schedules included therein, at the time filed


                                      -25-<PAGE>







         (and, in the case of registration statements and proxy
         statements, on the dates of effectiveness and the dates of
         mailing, respectively) (i) did not contain any untrue statement
         of a material fact or omit to state a material fact required to
         be stated therein or necessary in order to make the statements
         therein, in light of the circumstances under which they were
         made, not misleading, and (ii) complied in all material
         respects with the applicable requirements of the Exchange Act
         and the Securities Act, as the case may be.  The financial
         statements of Raytheon included in the Raytheon SEC Documents
         at the time filed (and, in the case of registration statements
         and proxy statements, on the date of effectiveness and the date
         of mailing, respectively) complied as to form in all material
         respects with applicable accounting requirements and with the
         published rules and regulations of the Commission with respect
         thereto, were prepared in accordance with GAAP applied on a
         consistent basis during the periods involved (except as may be
         indicated in the notes thereto or, in the case of unaudited
         statements, as permitted by Form 10-Q of the Commission), and
         fairly present (subject in the case of unaudited statements to
         normal, recurring audit adjustments) the consolidated financial
         position of Raytheon and its consolidated subsidiaries as at
         the dates thereof and the consolidated results of its
         operations and cash flows for the periods then ended.

                   Included in the Raytheon Disclosure Schedule are (i)
         audited consolidated balance sheets as of December 31, 1995 and
         1994, and consolidated statements of income, cash flows and
         shareholders' equity for the two years ended December 31, 1995
         and 1994, together with a report of Raytheon's independent
         accountants thereon, for Raytheon and its subsidiaries (such
         financial statements, the "Raytheon Statements" and the balance
         sheet as of December 31, 1995 included therein, the "Raytheon
         Balance Sheet"), and (ii) an unaudited consolidated balance
         sheet and statement of income, cash flows and shareholders'
         equity at and for the nine months ended September 29, 1996 for
         Raytheon and its subsidiaries (the "Raytheon Interim
         Statements").  The Raytheon Balance Sheet (including any
         related notes and schedules) and the consolidated balance sheet
         included in the Raytheon Interim Statements fairly present in
         all material respects the consolidated financial position of
         Raytheon and its subsidiaries as of their respective dates, and
         each of the consolidated statements of income, cash flows and
         shareholders' equity included in the Raytheon Statements and
         the Raytheon Interim Statements (including any related notes
         and schedules) fairly presents in all material respects the
         consolidated results of operations, retained earnings and cash
         flows, as the case may be, of Raytheon and its subsidiaries for
         the periods set forth therein, in each case in accordance with
         GAAP consistently applied except as disclosed in the footnotes
         thereto.

                   (b)  Proper accounting controls are, and since
         January 1, 1994, have been, in place to ensure that no portion
         of any international sales representative commission or
         contingent fee payment is included, directly or indirectly, in
         the contract price of any sale to


                                      -26-<PAGE>







         the United States Government pursuant to the FMS program, or
         any sale to a foreign government financed in whole or in part
         with funding from the FMF program, except as permitted
         thereunder and except where there is no reasonable likelihood
         that the failure to have in place such controls would give rise
         to any unreserved loss, cost or expense in excess of $10
         million individually or, when aggregated with the aggregate of
         those items excepted from the representations set forth in
         clause (c) below and in Sections 4.9 and 4.13, $100 million.

                   (c)  All payments to international sales
         representatives since January 1, 1994, including commission and
         contingent fee payments to international sales representatives
         on FMS and FMF contracts, (i) have been accurately reported on
         Raytheon's books and records, and (ii) have been made
         consistent with all applicable United States and foreign laws
         and regulations, except where there is no reasonable likelihood
         that the failure to accurately report or to be consistent with
         applicable law would give rise to any unreserved loss, cost or
         expense in excess of $10 million individually or, when
         aggregated with the aggregate of those items excepted from the
         representations set forth in clause (b) above and in Sections
         4.9 and 4.13, $100 million.

                   Section 4.7.  Registration Statement.  None of the
         information provided by or on behalf of Raytheon for inclusion
         in the Registration Statement, including the Prospectus, at the
         time it becomes effective, or in the Proxy Statement, at the
         date of mailing or at the date of voting or consent and
         approval with respect thereto, and none of the information
         provided by Raytheon for inclusion in GM's proxy statement or
         consent solicitation statement regarding the GM Transactions
         (the "GM Proxy Statement") at the date of mailing or at the
         date of voting or consent and approval with respect thereto,
         will contain any untrue statement of a material fact or omit to
         state any material fact required to be stated therein or
         necessary in order to make the statements therein, in light of
         the circumstances under which they are made, not misleading.
         The Proxy Statement, except for such portions thereof that
         relate only to GM or Hughes, and such portions of the
         Registration Statement that relate only to Raytheon, will
         comply as to form in all material respects with the provisions
         of the Securities Act and the Exchange Act.

                   Section 4.8.  Compliance with Law.  Raytheon and its
         subsidiaries are in compliance with, and at all times since
         December 31, 1994 have been in compliance with, all Applicable
         Law relating to them or their businesses or properties,
         including, without limitation, the Truth-In-Negotiations Act,
         the Procurement Integrity Act, the Foreign Corrupt Practices
         Act and the Cost Accounting Standards, except where the failure
         to be in compliance therewith would not have a material adverse
         effect on Raytheon.

                   Section 4.9.  Litigation.  Except as set forth in
         Section 4.9 to the Raytheon Disclosure Schedule, there is no
         Action pending or, to the knowledge of Raytheon, threatened
         against Raytheon or any of its subsidiaries, nor are there any
         facts known to Raytheon which would support an Action, which
         has any reasonable likelihood of resulting in unreserved
         liability to Raytheon or its subsidiaries in excess of $10
         million individually or, when aggregated with the aggregate of
         those items excepted from the representations set forth in
         Sections 4.6(b) and (c) and Section 4.13, $100 million or a
         material adverse effect on the ability of Raytheon to
         consummate the transactions contemplated hereby.  Raytheon is
         not subject to any outstanding order, writ, injunction or
         decree which, individually or in the aggregate, insofar as can
         be reasonably foreseen, could have a material adverse effect on
         Raytheon or on its ability to consummate the transactions
         contemplated hereby.  Except as set forth in Section 4.9 to the
         Raytheon Disclosure Schedule, since December 31, 1994, neither
         Raytheon nor any of its significant subsidiaries has been
         subject to any outstanding order, writ, injunction or decree
         relating to its method of doing business or its relationship
         with past, existing or future users or purchasers of any goods
         or services of Raytheon or any such subsidiaries.

                   Section 4.10.  Taxes.  Raytheon and its subsidiaries
         have duly filed all federal and material state, local and
         foreign income, franchise, excise, real and personal property
         and other tax returns and reports (including, but not limited
         to, those filed on a consolidated, combined or unitary basis)
         required to have been filed by them prior to the date hereof
         (taking into account extensions).  All of the foregoing returns
         and reports are true and correct in all material respects, and
         Raytheon and its subsidiaries have paid or made adequate
         provision in the financial statements of Raytheon included in
         the Raytheon Disclosure Schedule for all taxes payable in
         respect of all periods ending on or prior to September 30,
         1996.  None of Raytheon or any of its subsidiaries (i) will
         have any liability for any taxes in excess of the amounts so
         paid or reserves so established, (ii) is delinquent in the
         payment of any tax, assessment or governmental charge or (iii)
         has requested any extension of time within which to file any
         returns in respect of any fiscal year which have not since been
         filed, except, in each case, where such liability, delinquency
         or failure to request such an extension would not have a
         material adverse effect on Raytheon.  No deficiencies for any
         tax, assessment or governmental charge have been proposed in
         writing, asserted or assessed (tentatively or definitely), in
         each case, by any taxing authority, against Raytheon or any of
         its subsidiaries for which there are not adequate reserves.
         Except as set forth in Section 4.10 to the Raytheon Disclosure
         Schedule, none of Raytheon or any of its subsidiaries is the
         subject of any tax audit which could reasonably be expected to
         have a material adverse effect on Raytheon.  As of the date of
         this Agreement, there are no pending requests for waivers of
         the time to assess any such tax, other than those made in the
         ordinary course and for which payment has been made or there
         are adequate reserves.  The consolidated federal income tax


                                      -28-<PAGE>







         returns of Raytheon through the fiscal year ending December 31,
         1991 have been audited by the Internal Revenue Service.

                   Section 4.11.  Absence of Certain Changes.  (a)
         Except as set forth in Section 4.11 to the Raytheon Disclosure
         Schedule, since September 29, 1996, the businesses of Raytheon
         and its subsidiaries have been conducted in the ordinary
         course, consistent with past practice, and there has been no
         (i) material adverse change in the assets, liabilities, results
         of operations, business or financial condition of Raytheon and
         its subsidiaries taken as a whole or (ii) material adverse
         effect on the ability of Raytheon to consummate the
         transactions contemplated hereby.

                   (b)  Except as set forth in Section 4.11 to the
         Raytheon Disclosure Schedule, since September 29, 1996, neither
         Raytheon nor any of its subsidiaries has taken any action
         referred to in clauses (i) through (vi) of Section 5.3(b)
         hereof.

                   Section 4.12.  Undisclosed Liabilities.  Except as
         and to the extent disclosed or reserved against on the Raytheon
         Interim Statements, neither Raytheon nor any of its
         subsidiaries has any liabilities or obligations of any nature,
         whether known or unknown, absolute, accrued, contingent or
         otherwise, and whether due or to become due except (i) as set
         forth in Section 4.12 to the Raytheon Disclosure Schedule, (ii)
         as incurred after the date of the Raytheon Interim Statements
         in the ordinary course of business consistent with prior
         practice, or (iii) for liabilities and obligations which are
         not, individually or in the aggregate, material to Raytheon and
         its subsidiaries, taken as a whole.

                   Section 4.13.  Environmental Matters.  (a)  There
         are, with respect to Raytheon and its subsidiaries, and to
         Raytheon's knowledge with respect to its and their
         predecessors, no past or present material violations of
         Environmental Laws, releases of any material into the
         environment, actions, activities, circumstances, conditions,
         events, incidents, or contractual obligations which may give
         rise to any liability under any applicable Environmental Laws
         and none of Raytheon or its subsidiaries has received any
         notice with respect to any of the foregoing, nor is any Action
         pending or to Raytheon's knowledge threatened in connection
         with any of the foregoing;

                   (b)  Raytheon is in material compliance with all
         applicable Environmental Laws;

                   (c)  Raytheon has all valid permits required under
         Environmental Laws for the operation of its business as
         presently conducted; 


                                      -29-<PAGE>







         except, in each case, for any of the foregoing matters that
         would not reasonably be expected to result in Raytheon or its
         subsidiaries incurring unreserved losses, costs or expenses in
         excess of $10 million individually or, when aggregated with the
         aggregate of those items excepted from the representations set
         forth in Sections 4.6(b) and (c) and Section 4.9, $100 million,
         and except as is set forth in Section 4.9 or 4.13 to the
         Raytheon Disclosure Schedule.

                   Section 4.14.  Employee Benefits.  (a)  Section
         4.14(a) of the Raytheon Disclosure Schedule sets forth a
         complete and correct list of:  (i) all "employee benefit
         plans", as defined in Section 3(3) of ERISA, which Raytheon
         and/or its subsidiaries maintain (the "Raytheon Employee
         Benefit Plans") and (ii) all material employment agreements,
         and all material bonus and other incentive compensation,
         deferred compensation, disability, severance, stock award,
         stock option or stock purchase agreements, collective
         bargaining agreements, workers' compensation, policies and
         arrangements with respect to the employment and termination of
         employment of any officer, director or other employee whose
         principal place of employment is or was in the United States
         under which Raytheon or its subsidiaries could have any
         liability (the "Raytheon Employee Arrangements").  

                   (b)  With respect to each Raytheon Employee Benefit
         Plan and Raytheon Employee Arrangement, a complete and correct
         copy of each of the following documents has been provided or
         made available to Hughes: (i) the most recent plan document or
         agreement, and all amendments thereto and all related trust
         documents; (ii) the most recent summary plan description, and
         all related summaries of material modifications; and (iii) the
         most recent actuarial and financial reports.

                   (c)  Except as set forth in Section 4.14(c) of the
         Raytheon Disclosure Schedule, none of the Raytheon Employee
         Benefit Plans is subject to Section 4063, 4064 or 4202 of
         ERISA.

                   (d)  With respect to each Raytheon Employee Benefit
         Plan that is subject to Title IV or Section 302 of ERISA or
         Section 412 or 4971 of the Code (other than a Multiemployer
         Plan), except as would not have a material adverse effect on
         Raytheon:  (i) there does not exist any accumulated funding
         deficiency within the meaning of Section 412 of the Code or
         Section 302 of ERISA, whether or not waived; (ii) the fair
         market value of the assets of such Plan equals or exceeds the
         actuarial present value of all accrued benefits under the Plan
         (whether or not vested), on a termination basis; (iii) other
         than the consummation of the transactions contemplated by this
         Agreement, no reportable event within the meaning of Section
         4043(c) of ERISA has occurred; and (iv) all premiums to the
         Pension Benefit Guaranty Corporation have been paid in full and
         there are no outstanding penalties or interest


                                      -30-<PAGE>







         assessments.  With respect to each Raytheon Employee Benefit
         Plan which is a Multiemployer Plan, except as would not have a
         material adverse effect on Raytheon:  (i) no Withdrawal
         Liability exists that has not been satisfied in full; (ii) if
         Raytheon or any of its subsidiaries were to experience a
         withdrawal or partial withdrawal from such Plan, no Withdrawal
         Liability would be incurred; and (iii) neither Raytheon nor any
         of its subsidiaries has received any notification, nor has any
         reason to believe, that any such Plan is in reorganization, has
         been terminated, or may reasonably be expected to be in
         reorganization or to be terminated.

                   (e)  All contributions required to have been made by
         Raytheon or its subsidiaries under any Raytheon Employee
         Benefit Plan or any Applicable Law to any trusts established
         thereunder or in connection therewith have been made by the due
         date therefor (including any valid extensions), except where
         any failure to contribute would not, individually or in the
         aggregate, have a material adverse effect on Raytheon.

                   (f)  The Raytheon Employee Benefit Plans and Raytheon
         Employee Arrangements have been maintained, in all material
         respects, in accordance with their terms and Applicable Law,
         including but not limited to the filing of applicable reports,
         documents and notices regarding any Raytheon Employee Benefit
         Plans with the Secretary of Labor and the Secretary of the
         Treasury, or the furnishing of such documents to participants
         in the Raytheon Employee Benefit Plans, except where any
         failure to comply would not, individually or in the aggregate,
         have a material adverse effect on Raytheon.

                   (g)  With respect to each Raytheon Employee Benefit
         Plan that is intended to be a "qualified plan" within the
         meaning of Section 401(a) of the Code (a "Qualified Plan"),
         either the Internal Revenue Service has issued a favorable
         determination letter that has not been revoked, or an
         application for a favorable determination letter was timely
         submitted to the Internal Revenue Service for which no final
         action has been taken by the Internal Revenue Service, and
         there are no existing circumstances nor any events that have
         occurred that could adversely affect the qualified status of
         any Qualified Plan or the related trust, except to the extent
         such circumstances or events can be cured without a material
         adverse effect on Raytheon.  Each Raytheon Employee Benefit
         Plan which is intended to meet the requirements of Section
         501(c)(9) of the Code meets such requirements and provides no
         disqualified benefits (as such term is defined in Section
         4976(b) of the Code), except as would not have a material
         adverse effect on Raytheon.

                   Section 4.15.  Brokerage and Finder's Fees.  Except
         for Raytheon's obligations to Bear, Stearns & Co. Inc. and
         Credit Suisse First Boston Corporation, neither Raytheon nor
         any of its affiliates, stockholders, directors, officers or
         employees has incurred


                                      -31-<PAGE>







         or will incur on behalf of Raytheon or any affiliate of
         Raytheon, any brokerage, finder's or similar fee in connection
         with the transactions contemplated by this Agreement.  A copy
         of all agreements relating to any such fees payable by Raytheon
         or any affiliate of Raytheon has (or upon request will be)
         delivered to Hughes.

                   Section 4.16.  Opinion of Financial Advisor.  The
         Board of Directors of Raytheon has received (a) the opinion of
         Bear, Stearns & Co. Inc. to the effect that, as of January 16,
         1997, the financial terms of the Merger are fair to the
         Raytheon Stockholders from a financial point of view and (b)
         the opinion of Credit Suisse First Boston Corporation to the
         effect that, as of January 16, 1997, the Merger Consideration
         (as defined in such opinion) is fair to the Raytheon
         Stockholders from a financial point of view, and on or promptly
         following the date hereof such opinions will be confirmed in
         writing.  Raytheon, promptly upon receipt thereof, will provide
         a copy of such written opinions to Hughes. Neither of such
         opinions has been withdrawn, revoked or modified.

                   Section 4.17.  Board Recommendation.  The Board of
         Directors of Raytheon, at a meeting duly called and held, has
         by the unanimous vote of all directors present (i) determined
         that this Agreement and the transactions contemplated hereby
         are fair to and in the best interests of Raytheon and the
         Raytheon Stockholders and (ii) resolved to recommend that the
         Raytheon Stockholders approve this Agreement and the
         transactions contemplated hereby.

                   Section 4.18.  Voting Requirements.  The affirmative
         vote of the holders of a majority of all outstanding shares of
         Raytheon Common Stock, voting as a single class, at the
         Raytheon stockholders meeting to adopt and approve this
         Agreement, is the only vote of the holders of any class or
         series of Raytheon capital stock or indebtedness necessary to
         approve and adopt this Agreement and the transactions
         contemplated hereby.

                   Section 4.19.  DGCL Section 203 and State Takeover
         Laws.  Prior to the date hereof, the Board of Directors of
         Raytheon has taken all action necessary to exempt under or make
         not subject to (x) Section 203 of the DGCL and (y) to its
         knowledge, any other state takeover law or state law that
         purports to limit or restrict business combinations or the
         ability to acquire or vote shares (i) the execution of this
         Agreement, (ii) the Merger and (iii) the transactions
         contemplated hereby.

                   Section 4.20.  Permits.  Raytheon and its
         subsidiaries have in effect all federal, state, local and
         foreign Permits necessary for them to own, lease and operate
         their properties and assets and to carry on their business as
         now conducted or as presently contemplated to be conducted, and
         there has occurred no default under any such Permit, except for
         the absence of Permits and for defaults under Permits which
         absence or defaults, individually or in the aggregate, would
         not have a material adverse effect on Raytheon.

                   Section 4.21.  Restrictive Agreements.  As of the
         date hereof, except as set forth in Section 4.21 of the
         Raytheon Disclosure Schedule, Raytheon and its subsidiaries
         will not be parties to or bound by any agreement, contract,
         policy, license, Permit, document, instrument, arrangement or
         commitment that materially limits, after the Effective Time,
         the ability of Raytheon or any of its subsidiaries to compete
         in any line of business or with any person or in any geographic
         area or which would so limit, after the Effective Time, the
         ability of the Surviving Corporation or any subsidiary thereof.

                   Section 4.22.  Real Estate.  Each of Raytheon and its
         subsidiaries (i) has good and marketable title to its owned
         real properties and (ii) has valid and subsisting leasehold
         interests in its leased real properties, in each case free and
         clear of any liens or encumbrances of whatsoever nature, other
         than liens and encumbrances which would not reasonably be
         expected to have a material adverse effect on Raytheon.  The
         real property leased or owned by Raytheon or any of its
         subsidiaries (including, without limitation, all buildings,
         structures, improvements and fixtures located thereon,
         thereunder, thereover or therein, and all appurtenances thereto
         and other aspects thereof):  (1) is in good operating condition
         and repair and is structurally sound and free of defects, with
         no material alterations or repairs being required thereto under
         applicable law or insurance company requirements; and (2) is
         otherwise suitable, sufficient, adequate and appropriate in all
         respects (whether physical, structural, operational, legal,
         practical or otherwise) for its current use, operation and
         occupancy, except, in each such case, to the extent that
         failure to meet such standards would not reasonably be expected
         to have a material adverse effect on Raytheon.  No material
         real property owned or leased by Raytheon or any of its
         subsidiaries is subject to any sales contracts, option, right
         of first refusal or similar agreement or arrangement with any
         third party.

                   Section 4.23.  Employees.  (a) There is no labor
         strike or work stoppage pending or, to the knowledge of
         Raytheon, threatened against Raytheon or any of its
         subsidiaries that, individually or in the aggregate, has had or
         would reasonably be expected to have a material adverse effect
         on Raytheon.  Except as set forth in Section 4.23 of the
         Raytheon Disclosure Schedule, neither Raytheon nor any of its
         subsidiaries is a party to any collective bargaining agreement,
         nor has Raytheon received, within the past 12 months, any


                                      -33-<PAGE>







         demand or request for recognition by a labor organization
         purporting to represent any employees of Raytheon or its
         subsidiaries.

                   (b)  Except as set forth in Section 4.23 of the
         Raytheon Disclosure Schedule, neither Raytheon nor any of its
         subsidiaries is a party to any severance or change-in-control
         plan or agreement which could entitle any employee of Raytheon
         or any such subsidiary to payments as a result of the
         consummation of the transactions contemplated by this
         Agreement.

                   Section 4.24.  Shareholder Rights Plan.  There does
         not exist any shareholder rights plan or any outstanding rights
         issued by Raytheon with respect to any of Raytheon's securities
         (other than as disclosed in Section 4.4(a)(iii) or Section 4.4
         of the Raytheon Disclosure Schedule).


                                    ARTICLE 5

                             COVENANTS OF THE PARTIES

                   The parties hereto agree as follows with respect to
         the period from and after the execution of this Agreement.

                   Section 5.1.  Mutual Covenants.

                   (a)  General.  Each of the parties hereto shall use
         all commercially reasonable efforts to take all action and to
         do all things necessary, proper or advisable to consummate the
         Merger and the transactions contemplated by this Agreement
         (including using all commercially reasonable efforts to cause
         the conditions set forth in Article 6 for which they are
         responsible to be satisfied as soon as practicable and to
         prepare, execute and deliver such further instruments and take
         or cause to be taken such other and further action as any other
         party hereto shall reasonably request), subject to the
         limitations in Section 5.1(b) below.

                   (b)  HSR Act.  As soon as practicable, and in any
         event no later than ten (10) business days after the date
         hereof, each of the parties hereto shall file any Notification
         and Report Forms and related material required to be filed by
         it with the Federal Trade Commission and the Antitrust Division
         of the United States Department of Justice under the HSR Act
         with respect to the Merger and shall promptly make any further
         filings pursuant thereto that may be necessary, proper or
         advisable.  Each of Raytheon and Hughes shall



                                      -34-<PAGE>







         furnish to the other such information and assistance as the
         other reasonably may request in connection with the preparation
         of any submissions to, or agency proceedings by, any
         Governmental Authority under the HSR Act or any comparable laws
         of foreign jurisdictions, and each of Raytheon and Hughes shall
         keep the other promptly apprised of any communications with,
         and inquiries or requests for information from, such
         Governmental Authorities.  Each of Raytheon and Hughes hereby
         agrees to use its best efforts to cause the condition set forth
         in Section 6.1(b) of this Agreement to be satisfied, including,
         without limitation, by disposing of or holding separate, or
         agreeing to dispose of or hold separate, any assets (but in the
         case of Hughes, only Hughes Assets, as defined in the
         Separation Agreement).

                   Each of Raytheon and Hughes hereby agrees to use its
         best efforts to cooperate and assist in any defense by the
         other party hereto of the Merger before any Governmental
         Authority reviewing the Merger, including by promptly providing
         such information as may be requested by such Governmental
         Authority or such assistance as may be reasonably requested by
         the other party hereto in such defense.

                   (c)  Tax-Free Treatment.  The parties intend the
         Merger to qualify as a reorganization under Section 368(a) of
         the Code and certain of the transactions contemplated by the
         Hughes Distribution Agreement (the "Spin-Off Transactions") to
         qualify as tax-free spin-offs within the meaning of Sections
         355 and 368(a)(1)(D) of the Code.   Each of the parties and its
         affiliates shall use all commercially reasonable efforts to
         cause the Merger and the Spin-Off Transactions to so qualify
         and to obtain, as of the Effective Time, the opinions (the "Tax
         Opinions") of Wachtell, Lipton, Rosen & Katz, special counsel
         to Raytheon, and Weil, Gotshal & Manges LLP, special counsel to
         Hughes, substantially in the forms attached hereto as Exhibits
         G and H (or otherwise in form and substance satisfactory to
         Raytheon or Hughes, respectively), in each case to the effect
         that the Merger shall qualify as a reorganization within the
         meaning of Section 368 of the Code, it being understood that in
         rendering such Tax Opinions, such tax counsel shall be entitled
         to rely upon, inter alia, representations of officers of
         Raytheon and Hughes substantially in the form of Exhibits I and
         J. Neither party hereto nor its affiliates shall take any
         action that would cause the Merger not to qualify as a
         reorganization under Section 368(a) or that would cause the
         Spin-Off Transactions not to qualify as tax-free spin-offs
         within the meaning of Sections 355 and 368(a)(1)(D) of the
         Code.  The parties shall take the position for all purposes
         that the Merger qualifies as a reorganization under Section
         368(a) of the Code, and the Spin-Off Transactions qualify as
         tax-free spin-offs within the meaning of Sections 355 and
         368(a)(1)(D) of the Code, unless and until the parties fail to
         obtain either of the Tax Opinions as of the Closing Date.


                                      -35-<PAGE>







                   (d)  NYSE Listing.  The parties hereto shall use all
         commercially reasonable efforts to cause the shares of Hughes
         Class A Common Stock and Hughes Class B Common Stock to be
         issued pursuant to the Hughes Distribution Agreement and the
         Merger, respectively, to be approved for listing on the NYSE,
         subject to official notice of issuance, prior to the Closing
         Date.

                   (e)  Letters of Accountants.  Hughes shall use all
         commercially reasonable efforts to cause to be delivered to
         Raytheon two letters from Hughes' independent accountants, one
         dated a date within two business days before the date on which
         the Registration Statement shall become effective and one dated
         a date within two business days before the date on which the
         Proxy Statement is mailed to Raytheon Stockholders, in each
         case addressed to Raytheon, in form and substance reasonably
         satisfactory to Raytheon and customary in scope and substance
         for comfort letters delivered by independent public accountants
         in connection with registration statements similar to the
         Registration Statement and proxy statements similar to the
         Proxy Statement.

                   Raytheon shall use all commercially reasonable
         efforts to cause to be delivered to Hughes two letters from
         Raytheon's independent accountants, one dated a date within two
         business days before the date on which the Registration
         Statement shall become effective and one dated a date within
         two business days before the date on which the Proxy Statement
         is mailed to Raytheon Stockholders, in each case addressed to
         Hughes, in form and substance reasonably satisfactory to Hughes
         and customary in scope and substance for comfort letters
         delivered by independent public accountants in connection with
         registration statements similar to the Registration Statement
         and proxy statements similar to the Proxy Statement.

                   (f)  Public Announcements.  Unless otherwise required
         by Applicable Law or requirements of the NYSE (and in that
         event only if time does not permit), at all times prior to the
         earlier of the Effective Time or termination of this Agreement
         pursuant to Section 7.1, the parties hereto shall consult with
         each other before issuing any press release or other public
         announcement with respect to the Merger or the other
         transactions and matters contemplated hereby and shall not
         issue any such press release or public announcement prior to
         such consultation, provided that the initial press release
         relating to this Agreement and the transactions contemplated
         hereby will be a joint press release.

                   (g)  Access.  From and after the date of this
         Agreement until the Effective Time (or the termination of this
         Agreement), Raytheon and Hughes shall permit representatives of
         the other to have appropriate access at all reasonable times to
         the other's premises, properties, books, records, contracts,
         tax records and documents to the extent related to Hughes'
         business (which, for purposes of this Section 5.1(g), shall
         mean Hughes' business


                                      -36-<PAGE>







         after giving effect to the consummation of HEC Reorganization)
         or Raytheon's business, as the case may be.  Information
         obtained by Raytheon and Hughes pursuant to this Section 5.1(g)
         shall be subject to the provisions of the confidentiality
         agreements between them, each dated February 7, 1996 (together,
         the "Confidentiality Agreement"), which agreements remain in
         full force and effect.

                   (h)  Indemnification.  From and after the Effective
         Time, the Surviving Corporation shall indemnify, defend and
         hold harmless each individual who is now, or has been at any
         time prior to the date hereof or who becomes prior to the
         Effective Time, an officer or director of Raytheon or Hughes or
         any of their respective subsidiaries (the "Indemnified
         Parties") against all losses, claims, damages, costs, expenses,
         liabilities or judgments or amounts that are paid in settlement
         with the approval of the Surviving Corporation (which approval
         shall not be unreasonably withheld) arising out of or in
         connection with any claim, action, suit, proceeding or
         investigation based in whole or in part on or arising in whole
         or in part out of (i) the fact that such person is or was a
         director or officer of Raytheon or Hughes or their respective
         subsidiaries, as the case may be, whether pertaining to any
         matter existing or occurring at or prior to the Effective Time
         and whether asserted or claimed prior to, or at or after, the
         Effective Time (but in the case of Hughes only insofar as
         relating to the Defense Business (as defined in the Separation
         Agreement)) and (ii) this Agreement or the transactions
         contemplated hereby, in each case to the full extent Raytheon
         or Hughes, as the case may be, would have been permitted under
         Delaware law and its certificate of incorporation and bylaws to
         indemnify such person, and the Surviving Corporation shall pay
         expenses reasonably incurred by an Indemnified Party in advance
         of the final disposition of any such action or proceeding to
         such Indemnified Party to the full extent permitted by law upon
         receipt of the undertaking contemplated by Section 145(e) of
         the DGCL.  Without limiting the generality of the foregoing, in
         the event any such claim, action, suit, proceeding or
         investigation is brought against any Indemnified Party (whether
         arising before or after the Effective Time), after the
         Effective Time, the Surviving Corporation (i) shall pay all
         reasonable fees and expenses of any counsel retained by any
         Indemnified Parties promptly as statements therefor are
         received, and (ii) shall use its commercially reasonable
         efforts to assist in the vigorous defense of any such matter,
         provided that the Surviving Corporation shall not be liable for
         any settlement of any claim effected without its written
         consent, which consent, however, shall not be unreasonably
         withheld.  Any Indemnified Party wishing to claim
         indemnification under this Section 5.1(h), upon learning of any
         such claim, action, suit, proceeding or investigation, shall
         notify the Surviving Corporation (but the failure so to notify
         the Surviving Corporation shall not relieve it from any
         liability which it may have under this Section 5.1(h) except to
         the extent such failure materially prejudices the Surviving
         Corporation), and shall deliver to the Surviving Corporation
         the undertaking, if any, contemplated by Section 145(e) of the
         DGCL.


                                      -37-<PAGE>







                   The provisions of this Section 5.1(h) are intended to
         be for the benefit of, and shall be enforceable by, each
         Indemnified Party, his or her heirs and his or her legal
         representatives.

                   (i)  Expenses.  Except as otherwise provided in this
         Agreement or the other Transaction Agreements, whether or not
         the Merger is consummated, the parties hereto shall pay their
         own costs and expenses associated with this Agreement and the
         transactions contemplated hereby.

                   (j)  Preparation of SEC Documents.  Hughes shall
         promptly furnish Raytheon, and Raytheon shall promptly furnish
         Hughes and GM, with all information concerning such party as
         may be requested for inclusion in the Proxy Statement, the
         Registration Statement and the GM Proxy Statement to be filed
         with the Commission with respect to the Merger, the GM Merger
         and the other transactions contemplated by this Agreement and
         the Hughes Distribution Agreement.  Hughes and Raytheon jointly
         shall prepare the Proxy Statement and the Registration
         Statement and shall cooperate with GM in the preparation of the
         GM Proxy Statement.  The parties shall use all commercially
         reasonable efforts to file the Proxy Statement with the
         Commission on a confidential basis as soon as is reasonably
         practicable after the date hereof.  If at any time prior to the
         Effective Time, any information pertaining to Raytheon or
         Hughes contained in or omitted from the Registration Statement,
         the Proxy Statement or the GM Proxy Statement makes such
         statements contained therein false or misleading, Raytheon or
         Hughes, as the case may be, shall promptly inform the other or
         GM, as appropriate, and promptly provide the information
         necessary to make the statements contained therein not false
         and misleading.  The parties shall use all commercially
         reasonable efforts to have the Registration Statement declared
         effective by the Commission on a date as close as reasonably
         practicable to the anticipated date of termination of any
         applicable waiting periods under the HSR Act and to maintain
         the effectiveness of the Registration Statement through the
         Effective Time.  Raytheon shall use all commercially reasonable
         efforts to mail to its stockholders the Proxy Statement on a
         date as soon as reasonably practicable after the effectiveness
         of the Registration Statement which shall include all
         information required under Applicable Law to be furnished to
         such stockholders in connection with the Merger and the
         transactions contemplated hereby.

                   (k)  No Solicitation.  Each of the parties hereto
         agrees that, during the term of this Agreement, without the
         consent of the other, it shall not, and shall not authorize or
         permit any of its subsidiaries or any of its or its
         subsidiaries' directors, officers, employees, agents or
         representatives, directly or indirectly, to solicit, initiate,
         knowingly encourage or facilitate, or furnish or disclose non-
         public information in furtherance of, any inquiries or the
         making of any proposal with respect to any merger,
         consolidation or other business


                                      -38-<PAGE>







         combination involving such party, or any acquisition of any
         capital stock or any material portion of the assets (except for
         acquisitions of assets in the ordinary course of business
         consistent with past practice and except for consummation of
         the GM Transactions) of such party, or any combination of the
         foregoing (in each case, a "Competing Transaction"), or
         negotiate, explore or otherwise engage in discussions with any
         person (other than the other party hereto or its respective
         directors, officers, employees, agents and representatives or,
         with respect to Hughes, its affiliates) with respect to any
         Competing Transaction or enter into any agreement, arrangement
         or understanding therefor requiring them to abandon, terminate
         or fail to consummate the Merger; provided, however, that
         Hughes' obligations under this Section 5.1(k) shall only apply
         with respect to a Competing Transaction that includes the
         Defense Business or the consummation of which would otherwise
         result in the termination or material breach of any of the
         Transaction Agreements, and provided further, that
         notwithstanding any other provision hereof, each party may (i)
         engage in discussions or negotiations with a third party who
         (without any solicitation, initiation, knowing encouragement,
         discussion or negotiation, directly or indirectly, by or with
         such party or its subsidiaries, or any of its or its
         subsidiaries' directors, officers, employees, agents or
         representatives after the date hereof) seeks to initiate such
         discussion or negotiations and may furnish such third party
         information concerning such party and its business, properties
         and assets if, and only to the extent that, in each case (A)
         (x) the third party has first proposed a Competing Transaction
         that is superior to the transactions contemplated by this
         Agreement and has demonstrated that the consideration necessary
         for the Competing Transaction is reasonably likely to be
         available (all as determined in good faith in each case by such
         party's Board of Directors after consultation with its
         financial advisors) and (y) such party's Board of Directors has
         concluded in good faith, on the basis of oral or written advice
         of outside counsel, that such action is necessary for the Board
         of Directors to act in a manner consistent with its fiduciary
         duties under Applicable Law and (B) prior to furnishing such
         information to or entering into discussions or negotiations
         with such person, such party shall have (x) provided prompt
         notice to the other party of its intent to furnish information
         to or enter into discussions or negotiations with such person
         or entity and a description of the financial and other terms of
         the proposed Competing Transaction (as well as all material
         revisions or modifications thereof), together with the evidence
         by which the third party which proposed such Competing
         Transaction demonstrated the likely availability of the
         consideration therefor, and (y) received from such person or
         entity an executed confidentiality agreement in reasonably
         customary form on terms not in the aggregate materially more
         favorable to such person or entity than the terms contained in
         the Confidentiality Agreement, (ii) with respect to Raytheon,
         comply with Rule 14e-2 promulgated under the Exchange Act with
         regard to a tender or exchange offer, and/or (iii) provided
         such party shall have terminated this Agreement pursuant to
         Section 7.1(i) hereof, accept a Competing Transaction from a
         third


                                      -39-<PAGE>







         party.  Each party hereto will immediately cease all existing
         activities, discussions and negotiations with any parties
         conducted heretofore with respect to any of the foregoing. 

                   (l)  Additional Agreements.  Each of Hughes and
         Raytheon will comply in all material respects with all
         applicable laws and with all applicable rules and regulations
         of any Governmental Authority in connection with its execution,
         delivery and performance of this Agreement and the transactions
         contemplated hereby. 

                   (m)  Blue Sky.  Hughes and Raytheon will use all
         commercially reasonable efforts to obtain prior to the
         Effective Time all necessary blue sky permits and approvals
         required to permit the distribution of the shares of Hughes
         Class B Common Stock to be issued in accordance with the
         provisions of this Agreement.

                   (n)  Notification of Certain Matters.  Each of Hughes
         and Raytheon shall notify the other promptly following the
         receipt of process with respect to any stockholder litigation
         initiated against it relating to the Merger, and from time to
         time upon the request of the other shall provide a summary of
         the status thereof.

                   Section 5.2.  Covenants of Hughes.

                   (a)  Conduct of Hughes' Operations.  During the
         period from the date of this Agreement to the Effective Time,
         Hughes (which for purposes of this Section 5.2(a) shall mean
         Hughes after giving effect to the consummation of the HEC
         Reorganization, as if the HEC Reorganization had been
         consummated as of the date of this Agreement), shall conduct
         its business and operations in the ordinary course except with
         respect to the consummation of the GM Transactions in
         accordance with the terms thereof as contemplated by the
         Transaction Agreements and except as expressly contemplated by
         this Agreement, the Separation Agreement, and the transactions
         contemplated hereby and thereby, and shall use all commercially
         reasonable efforts to maintain and preserve its business
         organization and its material rights and franchises and to
         retain the services of its officers and key employees and
         maintain relationships with customers, suppliers, lessees,
         licensees and other third parties to the end that their
         goodwill and ongoing business shall not be impaired in any
         material respect.  Without limiting the generality of the
         foregoing, during the period from the date of this Agreement to
         the Effective Time, Hughes shall not, except with respect to
         the consummation of the GM Transactions and except as otherwise
         expressly contemplated by this Agreement, the Separation
         Agreement and the transactions contemplated hereby and thereby
         or as otherwise set forth in Section 5.2(a) or Section 3.22 to
         the Hughes Disclosure Schedule, without the prior written
         consent of Raytheon:

         understanding or arrangement with respect to the purchase, sale
         or voting of its capital stock or issue any instrument

         or persons the value of which individually or in the aggregate
         exceeds $100 million or enter into any confidentiality
         agreement with any person with respect to any such transaction;

                   (v)  create any subsidiaries which are material to
         Hughes and which are not, directly or indirectly, wholly owned
         by Hughes;

                  (vi)  enter into or modify any employment, severance,
         termination or similar agreements or arrangements with, or
         grant any bonuses, salary increases, severance or termination

         forth in Article 3 becoming false or inaccurate;

                  (ix)  enter into or carry out any other transaction
         which is material to Hughes other than in the ordinary and

                                      -41-<PAGE>







                   (x)  take any action which could reasonably be
         expected to adversely affect or delay the ability of any
         parties hereto to obtain any approval of any Governmental
         Authority required to consummate the transaction contemplated
         hereby;

                  (xi)  settle any Actions, whether now pending or
         hereafter made or brought, on terms which include a material
         limitation on the business or operations of the Surviving
         Corporation;

                 (xii)  permit or cause any subsidiary to do any of the
         foregoing or agree or commit to do any of the foregoing; or

                (xiii)  agree in writing or otherwise to take any of the
         foregoing actions.

                   (b)  Notification of Certain Matters.  Hughes shall
         give prompt notice to Raytheon of (i) the occurrence or non-
         occurrence of any event the occurrence or nonoccurrence of
         which would cause any Hughes representation or warranty
         contained in this Agreement to be untrue or inaccurate in any
         material respect at or prior to the Effective Time and (ii) any
         material failure of Hughes to comply with or satisfy any
         covenant, condition or agreement to be complied with or
         satisfied by it hereunder; provided, however, that the delivery
         of any notice pursuant to this Section 5.2(b) shall not limit
         or otherwise affect the remedies available hereunder to
         Raytheon.

                   (c)  Debt.  As of or prior to the Effective Time,
         Hughes shall incur indebtedness for borrowed money (the
         principal amount of which is referred to as "Debt") in an
         amount equal to the Intercompany Payment Amount (as defined
         below) for the purpose of funding payments to one or more
         Affiliates of Hughes (which may include, without limitation,
         payments with respect to existing debt, dividends,
         distributions and/or contributions to capital) as of or prior
         to the Effective Time (collectively the "Intercompany
         Payment").  Hughes and Raytheon shall cooperate in connection
         with Hughes' negotiation of the terms and conditions relating
         to the Debt comprising the Intercompany Payment Amount, and
         Hughes shall not commit to incur such Debt without obtaining
         the consent of Raytheon to such terms and conditions, which
         consent shall not be unreasonably withheld or delayed. No
         interest in respect of the Debt comprising the Intercompany
         Payment Amount shall be accrued and unpaid at the Effective
         Time.  The "Intercompany Payment Amount" will be equal to
         $9,500,000,000 ($9.5 billion) minus the "Class A Common Stock
         Amount" (as defined below) and minus all other Debt of Hughes
         which is outstanding as of the Effective Time.  The "Class A
         Common Stock Amount" is equal to 102,630,503 multiplied by the
         average closing price of Raytheon Common Stock, regular way, on
         the New York Stock Exchange during the 30-day period ending 5
         days prior to the Effective Time, provided,


                                      -42-<PAGE>







         however, that in the event such average price is greater than
         $54.29 such price shall be deemed to be $54.29, and in the
         event such average price is less than $44.42, such price shall
         be deemed to be $44.42.

                   (d)  Adoption of Rights Plan.  Hughes shall take all
         action necessary to adopt a shareholder rights plan
         incorporating in all material respects the terms and provisions
         set forth in Exhibit K effective as of the Effective Time.

                   Section 5.3.  Covenants of Raytheon.

                   (a)  Raytheon Stockholders Meeting.  Raytheon shall
         take all action in accordance with the federal securities laws,
         the DGCL and its Certificate of Incorporation and bylaws
         necessary to obtain the consent and approval of Raytheon
         Stockholders with respect to the Merger, this Agreement, and
         the transactions contemplated hereby and thereby.  The
         stockholder vote or consent required for approval of this
         Agreement will be no greater than is provided in Section 4.17.
         Raytheon shall use all commercially reasonable efforts to
         solicit from its stockholders proxies to be voted at its
         stockholders meeting in favor of this Agreement pursuant to the
         Proxy Statement and, subject to the fiduciary duties of its
         Board of Directors, the Proxy Statement shall include the
         recommendation of the Board of Directors of Raytheon in favor
         of this Agreement and the Merger.  Raytheon shall use all
         commercially reasonable efforts to promptly and expeditiously
         secure any vote or consent of stockholders required by the
         DGCL, the applicable requirements of any securities exchange
         and Raytheon's Certificate of Incorporation and Bylaws to
         effect the Merger.

                   (b)  Conduct of Raytheon's Operations.  During the
         period from the date of this Agreement to the Effective Time,
         Raytheon shall conduct its business and operations in the
         ordinary course except as expressly contemplated by this
         Agreement and the transactions contemplated hereby and shall
         use all commercially reasonable efforts to maintain and
         preserve its business organization and its material rights and
         franchises and to retain the services of its officers and key
         employees and maintain relationships with customers, suppliers,
         lessees, licensees and other third parties to the end that
         their goodwill and ongoing business shall not be impaired in
         any material respect.  Without limiting the generality of the
         foregoing, during the period from the date of this Agreement to
         the Effective Time, Raytheon shall not, except as otherwise
         expressly contemplated by this Agreement and the transactions
         contemplated hereby, or pursuant to agreements, arrangements or
         understandings in effect as of the date hereof, which are
         disclosed in Section 5.3(b) to the Raytheon Disclosure
         Schedule, or as otherwise set forth in Section 5.3(b) to the
         Raytheon Disclosure Schedule, without the prior written consent
         of Hughes:

         respect to its securities: (A) adjust, split, combine,

         or pay any dividend (other than regular quarterly cash
         dividends consistent as to time of payment and amount with the
         dividends declared and paid during 1996) or distribution on, or
         directly or indirectly redeem, purchase or otherwise acquire,
         any shares of its capital stock or any securities or
         obligations convertible into or exchangeable for any shares of
         its capital stock (except for purchases of shares of Raytheon
         Common Stock by Raytheon in the open market, the aggregate
         number of which shares is not in excess of the number of shares
         of Raytheon Common Stock issued by Raytheon after the date
         hereof pursuant to the exercise of stock options by employees
         of Raytheon), (C) grant any person any right or option to
         acquire any shares of its capital stock other than in the
         ordinary course of business, consistent with past practice
         pursuant to existing option plans or the Raytheon Company
         Deferral Plan for Directors, the aggregate amount of which will
         not exceed the amount set forth in Section 5.3(b) to the
         Raytheon Disclosure Schedule, (D) issue, deliver or sell or
         agree to issue, deliver or sell any shares of its capital stock
         or any securities, instruments or obligations convertible into
         or exchangeable or exercisable for any shares of its capital
         stock or such securities (except pursuant to the exercise of
         options to purchase Raytheon Common Stock outstanding on the
         date hereof or the Raytheon Company Deferral Plan for Directors
         or created hereafter in accordance with this Section 5.3(b)(i))
         or (E) enter into any agreement, understanding or arrangement
         with respect to the sale or voting of its capital stock;

                  (ii)  except as may be required by changes in
         Applicable Law or accounting principles, change any method or
         principle of accounting in a manner that is inconsistent with
         past practice;

                 (iii)  take any action that would reasonably be
         expected to result in the representations and warranties set
         forth in Article 4 becoming false or inaccurate;

                  (iv)  take any action which could reasonably be
         expected to adversely affect or delay the ability of any
         parties hereto to obtain any approval of any Governmental
         Authority required to consummate the transaction contemplated
         hereby;

                   (v)  permit or cause any subsidiary to do any of the
         foregoing or agree or commit to do any of the foregoing; or

                  (vi)  agree in writing or otherwise to take any of the
         foregoing actions.

                   (c)  Notification of Certain Matters.  Raytheon shall
         give prompt notice to Hughes of (i) the occurrence or non-
         occurrence of any event the occurrence or non-


                                      -44-<PAGE>







         occurrence of which would cause any Raytheon representation or
         warranty contained in this Agreement to be untrue or inaccurate
         in any material respect at or prior to the Effective Time and
         (ii) any material failure of Raytheon to comply with or satisfy
         any covenant, condition or agreement to be complied with or
         satisfied by it hereunder; provided, however, that the delivery
         of any notice pursuant to this Section 5.3(c) shall not limit
         or otherwise affect the remedies available hereunder to Hughes.

                   (d)  Affiliates.  Prior to the Effective Time,
         Raytheon shall deliver to Hughes a letter identifying all
         persons who are, at the time this Agreement is submitted for
         adoption to the stockholders of Raytheon, "affiliates" of
         Raytheon for purposes of Rule 145 under the Securities Act.
         Raytheon shall use all reasonable efforts to cause each such
         person to deliver to the Surviving Corporation on or prior to
         the Effective Time a written agreement substantially in the
         form attached as Exhibit F.

                   (e)  Raytheon Securities Law Filings.  During the
         period from the earlier of (i) the date on which the
         registration statement for Hughes Class A Common Stock relating
         to the GM Proxy Statement is declared effective by the
         Commission and (ii) the date on which the Registration
         Statement is declared effective by the Commission, through and
         including the later of (x) the date of the meeting of
         Raytheon's Stockholders with respect to this Agreement or (y)
         the date of the meeting of GM's stockholders with respect to
         the GM Proxy Statement (or in the case of a consent
         solicitation, the date on which the requisite approval of the
         GM Transactions by the stockholders of GM shall have been
         obtained), Raytheon shall provide Hughes and GM with drafts of
         each filing under the Securities Act or the Exchange Act (other
         than a filing under the Exchange Act on Form 8-K with respect
         to matters not contemplated by the Transaction Agreements)
         which it proposes to make a reasonable period of time in
         advance of the filing thereof with the Commission, and shall
         consult with Hughes and GM as regards any comments or concerns
         raised by Hughes or GM with respect thereto, all with a view
         towards coordinating the disclosure contained in such filings
         with the disclosure to be contained in or incorporated by
         reference in the Registration Statement, the Prospectus, and
         the proxy statement or consent solicitation to be used by GM in
         connection with the GM Transactions.

         consummation of the Merger under the HSR Act shall have expired
         or been terminated and all approvals of, or filings with, any

         contemplated hereby shall have been obtained or made, other

         make which would have no material adverse effect on Hughes or

         than Governmental Authorities) required for the consummation of
         the transactions contemplated hereby shall have been obtained
         and shall be in full force and effect, unless the failure to

                   (g)  The shares of Hughes Class B Common Stock to be
         issued pursuant to the Merger shall have been authorized for

         of directors of GM, Hughes and HEC that on the basis of and
         subject to the assumptions and limitations and other matters
         set forth therein, the Aggregate Consideration (as defined
         therein) is fair to the GM Group (as defined therein) as a
         whole, together (if requested by Hughes or Raytheon) with a
         consent authorizing the use of such opinion in connection with

         therein, the financial terms of the Merger are fair to the
         stockholders of Raytheon from a financial point of view (with

         Boston Corporation) is fair to the stockholders of Raytheon

         shall be entitled to rely upon, inter alia, representations of

                   (k)  All state securities or blue sky permits or

                   Section 6.2.  Conditions to Obligations of Raytheon.
         The obligations of Raytheon to consummate the Merger and the
         transactions contemplated hereby shall be subject to the
         fulfillment of the following conditions unless waived by
         Raytheon:

                   (a)  The representations and warranties of Hughes set
         forth in Article 3 shall be true and correct on the date hereof
         and on and as of the Closing Date as though made on and as of
         the Closing Date (except for representations and warranties
         made as of a specified date, which need be true and correct
         only as of the specified date), except, in the case of the
         representations and warranties other than those set forth in
         Sections 3.6(b) and (c), the first two sentences of Section
         3.9, Section 3.13 and any representation or warranty that is
         qualified by the words "material adverse effect," for such
         inaccuracies which have not had and would not reasonably be
         expected to have a material adverse effect on Hughes or the
         Surviving Corporation; provided, however, that any and all
         actions taken by Hughes pursuant to Section 5.1(b) and the
         effects thereof on the representations and warranties of Hughes
         set forth in Article 3 shall be ignored for purposes of this
         Section 6.2(a).

                   (b)  Hughes shall have performed in all material
         respects each obligation and agreement and shall have complied
         in all material respects with each covenant to be performed and
         complied with by it hereunder at or prior to the Effective
         Time.

                   (c)  Hughes shall have furnished Raytheon with a

         been satisfied.

                   (d)  Since the date of this Agreement, except to the

                   (a)  The representations and warranties of Raytheon
         set forth in Article 4 shall be true and correct on the date
         hereof and on and as of the Closing Date as though made on and
         as of the Closing Date (except for representations and
         warranties made as of a specified date, which need be true and
         correct only as of the specified date), except, in the case of
         the representations and warranties other than those set forth
         in Sections 4.6(b) and (c), the first two sentences of Section
         4.9, Section 4.13 and any representation or warranty that is
         qualified by the words "material adverse effect," for such
         inaccuracies which have not had and would not reasonably be
         expected to have a material adverse effect on Raytheon or the
         Surviving Corporation; provided, however, that any and all
         actions taken by Raytheon pursuant to Section 5.1(b) and the
         effects thereof on the representations and warranties of

                   (b)  Raytheon shall have performed in all material
         respects each obligation and agreement and shall have complied

         Time.

                   (c)  Raytheon shall have furnished Hughes with a
         certificate dated the Closing Date signed on its behalf by its
         Chairman, President or any Vice President to the effect that
         the conditions set forth in Sections 6.3(a) and (b) have been
         satisfied.

                   (d)  Since the date of this Agreement, except to the
         extent contemplated by Section 4.11 to the Raytheon Disclosure
         Schedule, and except for any actions taken by Raytheon pursuant
         to Section 5.1(b) and any effects thereof upon Raytheon, there
         shall not have been any material adverse change in the assets,
         liabilities, results of operations, business or financial
         condition of Raytheon and its subsidiaries taken as a whole or
         any material adverse effect on the ability of Raytheon to

                   (a)  by mutual written consent of Hughes and
         Raytheon;

                   (b)  by either Hughes or Raytheon if any permanent
         injunction or other order of a court or other competent
         Governmental Authority preventing the consummation of the
         Merger or the GM Transactions shall have become final and
         nonappealable;

                   (c)  by either Hughes or Raytheon in the event of
         either: (i) a material breach by the other party of any
         representation or warranty contained herein which breach cannot
         be or has not been cured within 30 days after the giving of
         written notice to the breaching party of such breach; or (ii) a
         material breach by the other party of any of the covenants or
         agreements contained herein, which breach cannot be or has not
         been cured within 30 days after the giving of written notice to
         the breaching party of such breach;

                   (d)  by either Hughes or Raytheon if the Merger shall
         not have been consummated before December 31, 1997, unless

         Section 7.1(d) shall not be available to any party whose
         failure (or whose affiliate's failure) to perform any material
         covenant or obligation under this Agreement or under the GM
         Implementation Agreement, has been the cause of or resulted in
         the failure of the Merger to occur on or before such date);

                   (e)  by either Hughes or Raytheon if at the meeting
         of Raytheon Stockholders (including any adjournment or
         postponement thereof) the requisite vote of the Raytheon
         Stockholders to approve the Merger and the transactions
         contemplated hereby shall not have been obtained;

                   (f)  by either Raytheon or Hughes if at the
         respective meetings of holders of the GM $1 2/3 Common Stock

         postponements thereof) the requisite vote of each such class of
         stock of GM to approve the GM Transactions shall not have been
         obtained (or with respect to a consent solicitation in lieu of
         such meetings, the period to consent to such transactions shall
         have expired without the requisite consents having been
         obtained);

                   (g)  by either Hughes or Raytheon upon the occurrence
         of any event that has resulted in a material adverse change
         after the date hereof in the assets, liabilities, results of
         operations, businesses or financial condition of the other
         party and its subsidiaries, taken as a whole, or upon the
         occurrence of an event which could reasonably be expected to
         result in such a material adverse change with respect to such
         party or, after the Effective Time, the Surviving Corporation,
         excluding for all purposes of this clause (g), any actions
         taken by


                                      -50-<PAGE>







         Hughes or Raytheon pursuant to Section 5.1(b) and any effects
         thereof on Hughes or Raytheon or effects which could reasonably
         be expected to result from such actions on Hughes, Raytheon or,
         after the Effective Time, the Surviving Corporation;

                   (h)  by either Hughes or Raytheon if the Board of
         Directors of the other party or any committee of the Board of
         Directors of the other party (i) shall withdraw or modify in
         any adverse manner its approval or recommendation of this
         Agreement or the Merger, (ii) shall fail to reaffirm such
         approval or recommendation upon such party's request, (iii)
         shall approve or recommend any acquisition of the other party
         or a material portion of its assets or any tender offer for
         shares of its capital stock, in each case, other than by a
         party hereto or an affiliate thereof, or (iv) shall resolve to
         take any of the actions specified in clause (i) above of this
         subparagraph (h); 

                   (i)  by either Hughes or Raytheon upon five business
         days' prior notice to the other and upon payment of the amounts
         specified in Section 7.2 hereof, if, as a result of any offer,
         inquiry, solicitation or proposal with respect to any Competing
         Transaction received by such party after the date hereof from a
         person other than the other party to this Agreement or any of
         its affiliates, the Board of Directors of such party shall have
         concluded in good faith, after considering applicable
         provisions of state law and after giving effect to all
         adjustments which may be offered by the other party described
         below pursuant to this subparagraph (i), on the basis of oral
         or written advice of outside counsel, that such action is
         necessary for the Board of Directors to comply with its
         fiduciary duties under applicable law and prior to any such
         termination, such party shall, and shall cause its respective
         financial and legal advisors to, negotiate with the other party
         to this Agreement to seek to make such adjustments in the terms
         and conditions of this Agreement as would enable such party to
         proceed with the transactions contemplated hereby; or

                   (j)  by either Hughes or Raytheon if the GM
         Implementation Agreement shall have been terminated pursuant to
         its terms.

                   Section 7.2.  Effect of Termination.  In the event of
         the termination of this Agreement pursuant to Section 7.1, this
         Agreement, except for the provisions of Section 5.1(i) and the
         provisions of Section 7.2, shall become void and have no
         effect, without any liability on the part of any party or its
         directors, officers or stockholders.  Notwithstanding the
         foregoing, nothing in this Section 7.2 shall relieve any party
         to this Agreement of liability for a willful breach of any
         provision of this Agreement nor invalidate the provisions of
         the Confidentiality Agreement.  If this Agreement is terminated
         (A) by Raytheon pursuant to Section 7.1(h), (B) by Hughes
         pursuant to Section 7.1(i), (C) by either Raytheon or Hughes
         pursuant to Section 7.1(f) or pursuant to Section 7.1(j) (but
         with respect to Section 7.1(j)


                                      -51-<PAGE>







         only in the event the GM Implementation Agreement was
         terminated pursuant to Sections 5.1(d), 5.1(e) or 5.1(f)
         thereof or pursuant to Section 5.1(b) thereof solely as a
         result of the termination of the Hughes Distribution Agreement
         pursuant to Section 4(a)(i), 4(a)(ii) (other than with respect
         to a termination arising from a failure to obtain the opinion
         contemplated by Section 3(d) of the Hughes Distribution
         Agreement solely as a result of any matter that would also
         constitute a breach of the representations or warranties of
         Raytheon set forth herein) or 4(a)(v) thereof) or (D) by
         Raytheon or Hughes pursuant to Section 7.1(d) but only in the
         event the Merger shall not have been consummated as a result of
         the non-completion of the Spin-Off Merger (as defined in the
         Hughes Distribution Agreement) by reason solely of the failure
         to satisfy the condition set forth in Section 3(c) or the
         condition set forth in Section 3(j) of the Hughes Distribution
         Agreement or due solely to the failure of the Board of
         Directors of GM to determine the Hughes Distribution Ratio (as
         defined in the Hughes Distribution Agreement), then Hughes
         shall pay to Raytheon, within five business days of such
         termination in cash by wire transfer in immediately available
         funds to an account designated by Raytheon, in reimbursement
         for Raytheon's and its affiliates' expenses, an amount in cash
         equal to the aggregate amount of Raytheon's and its affiliates'
         actual documented out-of-pocket expenses incurred in connection
         with pursuing the transactions contemplated by this Agreement,
         including legal, accounting and investment banking fees, up to
         but not in excess of an amount equal to $20 million in the
         aggregate, and, if (x) following the date hereof but prior to
         the time of such termination a Competing Transaction involving
         the Defense Business shall have been commenced, publicly
         proposed, publicly disclosed or communicated to the Board of
         Directors of Hughes or (y) at any time within three months
         following such termination any agreement with respect to a
         Competing Transaction involving the Defense Business shall have
         been entered into or any such Competing Transaction shall have
         been consummated, then, in addition (except in the case of a
         termination pursuant to Section 7.1(i) where such amount
         already has been paid), Hughes shall pay to Raytheon, within
         five business days of such termination (or, in the case of
         clause (y), prior to the earlier of the signing or consummation
         of any such transaction) in cash by wire transfer in
         immediately available funds to an account designated by
         Raytheon a termination fee in an amount equal to $200 million.
         In the event this Agreement is terminated (A) by Hughes
         pursuant to Section 7.1(e) or 7.1(h), (B) by Raytheon pursuant
         to Section 7.1(e) or 7.1(i), or (C) by Raytheon or Hughes
         pursuant to Section 7.1(d) (but in the case of Section 7.1(d)
         only in the event the Merger shall not have been consummated as
         a result of the failure of the condition set forth in Section
         6.1(i) to have been satisfied at a time when all other
         conditions set forth in Article 6 (other than the condition set
         forth in Section 6.1(f)) shall have been satisfied or be
         capable of being satisfied, and only if the failure of the
         condition set forth in Section 6.1(i) to have been satisfied
         does not result from any matter that would also constitute a
         breach of the representations or warranties of Hughes set forth
         herein), then Raytheon shall pay to Hughes, within five
         business days of such termination in cash by wire


                                      -52-<PAGE>







         transfer in immediately available funds to an account
         designated by Hughes, in reimbursement for Hughes' and its
         affiliates' expenses, an amount in cash equal to the aggregate
         amount of Hughes' and its affiliates' actual documented out-of-
         pocket expenses incurred in connection with pursuing the
         transactions contemplated by this Agreement, including legal,
         accounting and investment banking fees, up to but not in excess
         of an amount equal to $20 million in the aggregate and if (x)
         following the date hereof but prior to the time of such
         termination a Competing Transaction involving Raytheon shall
         have been commenced, publicly proposed, publicly disclosed or
         communicated to the Board of Directors of Raytheon or (y) at
         any time within three months following such termination any
         agreement with respect to a Competing Transaction involving
         Raytheon shall have been entered into or any such Competing
         Transaction shall have been consummated, then, in addition
         (except in the case of a termination pursuant to Section 7.1(i)
         where such amount already has been paid), Raytheon shall pay to
         Hughes, within five business days of such termination (or, in
         the case of clause (y), prior to the earlier of the signing or
         consummation of any such transaction) in cash by wire transfer
         in immediately available funds to an account designated by
         Hughes a termination fee in an amount equal to $200 million.

                   Hughes and Raytheon agree that the agreements
         contained in this Section 7.2 are an integral part of the
         transactions contemplated by this Agreement and constitute
         liquidated damages and not a penalty.  If one party fails to
         pay to the other any fee due under this Section 7.2 in
         accordance with the terms hereof, the defaulting party shall
         pay the costs and expenses (including legal fees and expenses)
         in connection with any action, including the filing of any
         lawsuit or other legal action, taken to collect payment,
         together with interest on the amount of any unpaid fee at the
         publicly announced prime rate of Citibank, N.A. from the date
         such fee was required to be paid.

                   Section 7.3.  Amendment.  This Agreement may be
         amended by the parties hereto, by action taken or authorized by
         their respective Boards of Directors, at any time before or
         after adoption of this Agreement by Raytheon stockholders and
         before or after approval of the GM Transactions by GM's
         stockholders, but after either such approval or authorization,
         no amendment shall be made which by law requires further
         approval or authorization by the stockholders of GM or
         Raytheon, as the case may be, without such further approval or
         authorization.  Notwithstanding the foregoing, this Agreement
         may not be amended except by an instrument in writing signed on
         behalf of each of the parties hereto.

                   Section 7.4  Extension; Waiver.  At any time prior to
         the Effective Time, Hughes (with respect to Raytheon) and
         Raytheon (with respect to Hughes) by action taken or authorized
         by their respective Boards of Directors, may, to the extent
         legally allowed, (a) extend the time for the performance of any
         of the obligations or other acts of such party, (b)


                                      -53-<PAGE>







         waive any inaccuracies in the representations and warranties
         contained herein or in any document delivered pursuant hereto
         and (c) waive compliance with any of the agreements or
         conditions contained herein.  Any agreement on the part of a
         party hereto to any such extension or waiver shall be valid
         only if set forth in a written instrument signed on behalf of
         such party.

                   (b)  If any provision of this Agreement or the
         application thereof to any person or circumstance is determined
         by a court of competent jurisdiction to be invalid, void or

         application of such provision to persons or circumstances or in
         jurisdictions other than those as to which it has been held
         invalid or unenforceable, shall remain in full force and effect
         and shall in no way be affected, impaired or invalidated
         thereby, so long as the economic or legal substance of the
         transactions contemplated hereby is not affected in any manner
         adverse to any party.  Upon such determination, the parties
         shall negotiate in good faith in an effort to agree upon such a
         suitable and equitable provision to effect the original intent

                   Section 8.6.  Definitions of "subsidiary" and
         "significant subsidiary". When a reference is made in this
         Agreement to a subsidiary of a party, the term "subsidiary"
         means any corporation or other organization, whether
         incorporated or unincorporated, of which at least a majority of
         the securities or interests having by the terms thereof
         ordinary voting power to elect at least a majority of the board
         of directors or others performing similar functions with
         respect to such corporation or other organization is directly
         or indirectly owned or controlled by such party or by any one
         or more of its subsidiaries, or by such party and one or more
         of its subsidiaries.  When a reference is made in this
         Agreement to a significant subsidiary of a party, the phrase
         "significant subsidiary" means a subsidiary of such party that
         constitutes a "significant subsidiary" within the meaning of
         Rule 1-02 of Regulation S-X of the Commission.

                   Section 8.7.  Third Party Beneficiaries.  Other than
         the provisions of Sections 5.1(h), (a) the provisions of this
         Agreement are solely for the benefit of the parties and are not
         intended to confer upon any person except the parties any
         rights or remedies hereunder, and (b) there are no third party
         beneficiaries of this Agreement and this Agreement shall not
         provide any third person with any remedy, claim, liability,
         reimbursement, claim of action or other right in excess of
         those existing without reference to this Agreement.

                   Section 8.8.  Governing Law.  This Agreement shall be
         governed and construed in accordance with the laws of the State
         of Delaware without regard to principles of conflicts of law.

                   Section 8.9.  Specific Performance.  In the event of
         any actual or threatened default in, or breach of, any of the
         terms, conditions and provisions of this Agreement, the party
         or parties who are or are to be thereby aggrieved shall have
         the


                                      -57-<PAGE>







         right to specific performance and injunctive or other equitable
         relief of its rights under this Agreement, in addition to any
         and all other rights and remedies at law or in equity, and all
         such rights and remedies shall be cumulative.  The parties
         agree that the remedies at law for any breach or threatened
         breach, including monetary damages, are inadequate compensation
         for any loss and that any defense in any action for specific
         performance that a remedy at law would be adequate is waived.
         Any requirements for the securing or posting of any bond with
         such remedy are waived.

                   Section 8.10.  Assignment.  Neither this Agreement
         nor any of the rights, interests or obligations hereunder shall
         be assigned by any of the parties hereto (whether by operation
         of law or otherwise) without the prior written consent of the
         other party.  Subject to the preceding sentence, this Agreement
         shall be binding upon, inure to the benefit of and be
         enforceable by the parties and their respective successors and
         assigns.

                             IMPLEMENTATION AGREEMENT


                   This IMPLEMENTATION AGREEMENT ("Agreement") is made
         and entered into as of January 16, 1997 by and between General
         Motors Corporation, a Delaware corporation ("GM"), and Raytheon
         Company, a Delaware corporation ("Raytheon").  GM and Raytheon

         collectively as the "Parties."

                   WHEREAS, HE Holdings, Inc., a Delaware corporation
         and an indirect wholly owned subsidiary of GM ("Hughes"), and
         Raytheon desire to combine Raytheon's business with the Defense

         below));

                   WHEREAS, concurrently with the execution and delivery
         of this Agreement, Hughes and Raytheon are entering into an
         Agreement and Plan of Merger dated as of the date hereof (as
         amended from time to time in accordance with the terms thereof
         and hereof, the "Hughes Merger Agreement"), pursuant to which
         Raytheon shall merge with and into Hughes, with Hughes as the
         surviving corporation (the "Hughes Merger"), in accordance with
         the terms and subject to the conditions thereof;

                   WHEREAS, as a condition to entering into the Hughes
         Merger Agreement, Raytheon has required that GM and Hughes
         agree that, at the time of the consummation of the Hughes Merg-
         er, Hughes be an independent, publicly owned company, compris-
         ing the Defense Business;

                   WHEREAS, in response to such requirement, GM is will-
         ing to enter into this Agreement and, subject to satisfaction
         of certain conditions contained herein, an Agreement and Plan

         Agreement"), by and between GM and a wholly owned subsidiary of
         GM to be designated by GM ("Merger Sub");

                   WHEREAS, subject to satisfaction of certain condi-
         tions contained herein, the Master Separation Agreement, in the
         form attached hereto as Exhibit B (except as provided in Sec-
         tion 4.2(b) hereof) (the "Separation Agreement"), shall be ex-
         ecuted and delivered prior to the consummation of the transac-
         tions contemplated by the Hughes Distribution Agreement;

                   WHEREAS, pursuant to the Hughes Distribution Agree-
         ment, subject to certain terms and conditions contained there-
         in, Merger Sub shall merge with and into GM, with GM as the
         surviving corporation (the "Hughes Spin-Off Merger"), pursuant
         to which, among other things, the holders of shares of common
         stock, par value $1-2/3 per share, of GM ("GM $1-2/3 Common
         Stock") and the holders of shares of Class H Common Stock, par
         value $0.10 per share, of GM ("GM Class H Common Stock" and,
         together with GM $1-2/3 Common Stock, "GM Common Stock") shall
         receive a distribution of shares of Class A Common Stock, par
         value $0.01 per share, of  Hughes ("Hughes Class A Common
         Stock"), representing all of the outstanding common stock of
         Hughes; 

                   WHEREAS, the Parties intend that (a) the Hughes Merg-
         er constitute a tax-free "reorganization" within the meaning of
         Section 368(a) of the Internal Revenue Code of 1986, as amended

                   WHEREAS, by resolutions duly adopted, the respective
         Boards of Directors of each of GM and Raytheon have approved
         and adopted this Agreement and, by resolutions duly adopted,
         the respective Boards of Directors of each of Hughes and Ray-
         theon have approved the Hughes Merger Agreement;

                   NOW, THEREFORE, in consideration of the premises and
         the representations, warranties, covenants and agreements here-
         in contained, and for other good and valuable consideration,
         the receipt and sufficiency of which are hereby acknowledged,
         and intending to be legally bound hereby, the Parties hereby
         agree as follows:


                                    ARTICLE I

                               THE GM TRANSACTIONS

                   Section 1.1    Determination of the Hughes Distribu-
         tion Ratio.  GM's Board of Directors has determined that the GM
         Transactions, taken as a whole, are in the best interests of GM
         and its common stockholders, subject to the GM Board's determi-
         nation of a Hughes Distribution Ratio that would enable (i) the
         GM Board of Directors to conclude that, as of the date of such
         determination, the GM Transactions, taken as a whole, are in
         the best interests of GM and its common stockholders and fair
         to the holders of GM $1-2/3 Common Stock and the holders of GM
         Class H Common Stock and (ii) each of the GM Financial Advisors
         to provide a GM Financial Advisor Fairness Opinion.  Subject to
         the fiduciary duties of its Board of Directors and subject to
         the terms and provisions of this Agreement, GM agrees that its
         Board of Directors shall use all commercially reasonable ef-
         forts (i) to determine, in consultation with the GM Financial
         Advisors, a Hughes Distribution Ratio that satisfies each of
         the conditions set forth in the first sentence of this Section
         1.1 and (ii) to consummate the GM Transactions.

                   Section 1.2    Hughes Distribution Agreement.  Fol-
         lowing such time as (i) GM has determined a Hughes Distribution
         Ratio as contemplated by Section 1.1 above and (ii) each of the
         GM Financial Advisor Fairness Opinions has been rendered as
         contemplated by Section 1.1 above, GM and Merger Sub shall en-

         where owned, leased, used, operated and conducted.  GM is duly
         qualified to do business and in good standing in each jurisdic-
         tion in which the nature of the business conducted by it or the
         property it owns, leases, uses or operates make such qualifica-
         tion necessary, except where the failure to be so qualified or

         adverse effect on GM's ability to consummate the transactions
         on its part contemplated hereby. 

                   Section 2.2    Corporate Power and Authority.  Each
         of GM and each of its subsidiaries (other than with respect to

         gation of GM, enforceable against it in accordance with its

         action Agreements to which GM or any of its subsidiaries (other

         action on the part of GM or such subsidiary, as applicable
         (subject, in the case of the Hughes Distribution Agreement, to
         the receipt of the approval of GM common stockholders described

         other actions required under foreign, federal and state securi-

         ing that, individually or in the aggregate, would neither have
         a material adverse effect on the ability of GM and its subsid-
         iaries (other than Hughes and the subsidiaries of Hughes after
         giving effect to the consummation of the HEC Reorganization) to

         of GM or any such subsidiary to consummate the transactions on

         sary, proper or advisable to consummate the transactions con-
         templated hereby and by the other Transaction Agreements,
         including, without limitation, with respect to the satisfaction
         of the conditions set forth in Section 3 of the Hughes Distri-
         bution Agreement.  

                        (b)  Notification of Certain Matters.  Each of
         the Parties hereto shall give prompt notice to the other of (i)
         the occurrence or non-occurrence of any event the occurrence or
         non-occurrence of which would cause either Party's representa-
         tion or warranty contained in this Agreement to be untrue or
         inaccurate at or prior to the Effective Time (as defined in the
         Hughes Merger Agreement) and (ii) any material failure of
         either Party hereto to comply with or satisfy any covenant,
         condition or agreement to be complied with or satisfied by it
         hereunder; provided, however, that the delivery of any notice
         pursuant to this Section 4.1(b) shall not limit or otherwise
         affect the remedies available hereunder to either Party.

                        (c)  HSR Act.  As soon as practicable, and in
         any event no later than ten (10) business days after the date
         hereof, each of the Parties hereto shall file any Notification
         and Report Forms and related material required to be filed by
         it with the Federal Trade Commission and the Antitrust Division
         of the United States Department of Justice under the HSR Act
         with respect to the Hughes Merger and shall promptly make any
         further filings pursuant thereto that may be necessary, proper
         or advisable.  Each of Raytheon and GM shall furnish to the
         other such information and assistance as the other reasonably
         may request in connection with the preparation of any submis-
         sions to, or agency proceedings by, any Governmental Authority
         under the HSR Act or any comparable state laws or comparable
         laws of foreign jurisdictions, and each of Raytheon and GM
         shall keep the other promptly apprised of any communications
         with, and inquiries or requests for information from, such Gov-
         ernmental Authorities.  Each of Raytheon and GM hereby agrees
         to use its best efforts to cause the condition set forth in
         Section 6.1(b) of the Hughes Merger Agreement to be satisfied,
         including, without limitation, by disposing of or holding sepa-
         rate, or agreeing to dispose of or hold separate, any assets
         (but in the case of GM, only Hughes Assets, as defined in the
         Separation Agreement).  Each of Raytheon and GM hereby agrees
         to use its best efforts to cooperate and assist in any defense
         by the other party hereto of the Hughes Merger before any Gov-
         ernmental Authority reviewing the Hughes Merger, including by
         promptly providing such information as may be requested by such
         Governmental Authority or such assistance as may be reasonably
         requested by the other party in such defense.

                   Section 4.2    Covenants of GM.

                        (a)  No Solicitation.  GM agrees that, during
         the term of this Agreement, without the consent of Raytheon, it
         shall not, and shall not authorize or permit any of its subsid-
         iaries or any of its or its subsidiaries' directors, officers,
         employees, agents or representatives, directly or indirectly,
         to solicit, initiate, knowingly encourage or facilitate, or
         furnish or disclose non-public information in furtherance of,
         any inquiries or the making of any proposal with respect to any
         Competing Transaction (as defined in the Hughes Merger Agree-
         ment) relating to the Defense Business or the consummation of
         which would otherwise result in the termination or material
         breach of any of the Transaction Agreements, or negotiate, ex-
         plore or otherwise engage in discussions with any person (other
         than Raytheon or its respective directors, officers, employees,
         agents and representatives) with respect to any Competing
         Transaction or enter into any agreement, arrangement or under-
         standing therefor requiring them to abandon, terminate or fail
         to consummate the Hughes Merger except and to the extent (in-
         cluding compliance by GM with the conditions set forth therein)
         that Hughes could do so pursuant to the terms of Section 5.1(k)
         of the Hughes Merger Agreement.

                        (b)  Transaction Agreements.  Subject to the
         terms and provisions of this Agreement, GM shall, and shall
         cause its subsidiaries to, enter into the Transaction Agree-
         ments, as and when contemplated hereby and thereby.  GM agrees
         that it will consult with Raytheon regarding any changes,
         amendments or additions that are proposed to be made to any
         such agreement prior to the Effective Time, whether before or
         after any such agreement is entered into by the respective par-
         ties thereto.  Except for any amendment or change to the Hughes
         Distribution Agreement to reflect the determination of the
         Hughes Distribution Ratio or the terms of the new GM common
         stock to be set forth in Exhibit A thereto and except for any
         amendment to the Hughes Distribution Agreement as required pur-
         suant to Section 1.2 hereof, GM shall not permit any such
         change, amendment or addition to be made prior to the Effective
         Time to the forms or terms of any such agreement without
         Raytheon's consent (which consent shall not be unreasonably
         withheld or delayed), unless such change, amendment or addition
         could not reasonably be foreseen (i) to have an adverse effect
         on the business, assets, liabilities or financial condition of
         Hughes (after giving effect to the consummation of the HEC Re-
         organization) or, following the Effective Time, the Surviving
         Corporation or (ii) to delay materially the consummation of the
         Hughes Merger on the terms and subject to the conditions of
         this Agreement and the other Transaction Agreements.  Unless
         this Agreement has been terminated, GM agrees that it shall
         not, and shall not permit any of its subsidiaries to, terminate
         (except as may be permitted by the terms thereof) or waive any
         condition of any of the Transaction Agreements (other than the
         Hughes Merger Agreement), without the prior written consent of
         Raytheon.  GM shall not permit Hughes to make prior to the Ef-
         fective Time any formal election expressly referenced in the
         Separation Agreement to be made by Hughes unless any such elec-
         tion is acceptable to Raytheon.

                        (c)  Preparation of SEC Documents.  GM shall
         promptly furnish Raytheon with all information concerning GM
         (except as it relates to Hughes or its subsidiaries) as may be
         reasonably requested by Raytheon for inclusion in the Class B
         Registration Statement or the Raytheon Proxy Statement.  If at
         any time prior to the Effective Time, any information pertain-
         ing to GM (except as it relates to Hughes or its subsidiaries)
         contained in or omitted from the Class B Registration Statement
         or the Raytheon Proxy Statement makes such statements contained
         therein false or misleading, GM shall promptly inform Raytheon
         thereof and GM shall promptly provide 


                                      - 9 -<PAGE>


         
         the information necessary to make the statements contained
         therein not false or misleading.  For purposes of this Section
         4.2(c), "Hughes" shall mean Hughes after giving effect to the
         consummation of the HEC Reorganization, as if the HEC
         Reorganization had been consummated as of the date of this
         Agreement.     

                   Section 4.3    Covenants of Raytheon.                

                        (a)  Preparation of SEC Documents.  Raytheon
         shall promptly furnish GM with all information concerning it as
         may be reasonably requested by GM for inclusion in the Proxy/
         Consent Solicitation Statement.  Raytheon shall cooperate with
         GM in the preparation of the Proxy/Consent Solicitation State-
         ment.  If at any time prior to the Effective Time, any informa-
         tion pertaining to Raytheon contained in or omitted from the
         Proxy/Consent Solicitation Statement makes such statements con-
         tained therein false or misleading, Raytheon shall promptly
         inform GM thereof and Raytheon shall promptly provide the in-
         formation necessary to make the statements contained therein
         not false or misleading.  

                        (b)  Letter of Accountants.  Raytheon shall use
         all commercially reasonable efforts to cause to be delivered to
         GM in connection with the Proxy/Consent Solicitation Statement
         two letters from Raytheon's independent accountants, one dated
         a date within two business days before the date on which the
         Proxy/Consent Solicitation Statement shall become effective and
         one dated a date within two business days before the date on
         which the Proxy/Consent Solicitation Statement is mailed to
         GM's common stockholders, in each case addressed to GM, in form
         and substance reasonably satisfactory to GM and customary in
         scope and substance for comfort letters delivered by indepen-
         dent public accountants in connection with registration state-
         ments and proxy or consent solicitation statements similar to
         the Proxy/Consent Solicitation Statement.  

                        (c)  Cooperation Regarding Tax Rulings and Opin-
         ions. Raytheon shall promptly furnish GM with all information
         concerning it as may be reasonably requested by GM (i) for in-
         clusion in any request for rulings and supplemental submissions
         ("Ruling Requests") filed by GM with the Internal Revenue Ser-
         vice of the U.S. Department of Treasury (the "IRS") with re-
         spect to the Hughes Merger and the GM Transactions, including
         any supplemental rulings sought from the IRS by GM to ensure
         the Tax-Free Status of the EDS Split-Off (as defined in the
         Hughes Distribution Agreement), and (ii) for use by GM's coun-
         sel in preparing any tax opinions requested by GM from such
         counsel with respect to the Hughes Merger and the GM Transac-
         tions (the "Tax Opinions").  Raytheon shall cooperate fully
         with GM in the preparation of the Ruling Requests and supple-
         mental submissions to the IRS, and shall make its officers,
         employees, advisers and others associated with Raytheon avail-
         able for meetings with GM and the IRS as reasonably requested
         by GM.  Raytheon shall provide GM with such representations and
         warranties as may be requested by the IRS or reasonably re-
         quested by GM in connection with the Ruling Requests or Tax
         Opinions. To the extent that Raytheon has any shareholders who
         beneficially own, directly or indirectly, five percent or more
         of the stock of Raytheon, Raytheon shall take such commercially
         reasonable actions as are necessary to obtain any representa-
         tions or warranties from such shareholders as may be requested
         by the IRS or reasonably requested by GM in connection with the
         Ruling Requests or Tax Opinions.  GM shall provide to Raytheon
         for its review and comment a draft of any Ruling Requests prior
         to the submission thereof to the IRS and shall allow Raytheon
         sufficient time to comment thereon.  GM shall consider in good
         faith all comments timely received from Raytheon on any Ruling
         Request.  Notwithstanding the foregoing, the form and substance
         of the Ruling Requests 


                                     - 10 -<PAGE>



         shall be solely in the discretion of GM and GM shall not be
         required to delay the filing of any Ruling Request pending the
         receipt or consideration of comments from Raytheon not timely
         received by GM.  GM shall provide Raytheon with the opportunity
         to participate in meetings with the IRS regarding the Ruling
         Requests.

                   Section 5.1    Termination.  This Agreement may be
         terminated at any time prior to the Effective Time:

                        (a)  by mutual written consent of GM and Ray-
         theon;

                        (b)  by either of GM or Raytheon at any time
         following the termination of either of the Hughes Merger Agree-
         ment or the Hughes Distribution Agreement in accordance with
         the terms thereof; 

                        (c)  by either of GM or Raytheon in the event of
         either: (i) a material breach by the other Party of any repre-
         sentation or warranty contained herein which breach cannot be
         or has not been cured within 30 days after the giving of writ-
         ten notice to the breaching Party of such breach; or (ii) a
         material breach by the other Party of any of the covenants or
         agreements contained herein, which breach cannot be or has not

         the breaching Party of such breach; 

                        (d)  by GM in the event that its Board of Direc-
         tors determines in good faith that it is unable to determine a
         Hughes Distribution Ratio as contemplated by Section 1.1 here-
         of;

                        (e)  by GM in the event that its Board of Direc-
         tors determines in good faith, in the exercise of its fiduciary
         obligations under applicable law, on the basis of oral or writ-
         ten advice of outside counsel, (i) that it either is unable to 
         include in the Proxy/Consent Solicitation Statement its recom-
         mendation in favor of the GM Transactions as then set forth in 
         the Hughes Distribution Agreement or must revoke or withdraw 
         the same and (ii) that the foregoing determination could not
         reasonably be avoided by adjusting the Hughes Distribution Ra-
         tio so as to satisfy the conditions set forth in the first sen-
         tence of Section 1.1 hereof as of the date of such adjustment;
         or

                        (f)  by Raytheon in the event that (i) the GM
         Board of Directors shall have made a determination described in
         Section 5.1(d) or Section 5.1(e) and shall not have terminated
         this Agreement within 10 business days thereof, (ii) the GM
         Board of Directors shall not have determined a Hughes Distribu-
         tion Ratio as contemplated by Section 1.1 hereof by the date
         which is 30 business days after the latest of (x) the receipt
         by GM of the Ruling (as defined in the Hughes Distribution
         Agreement), (y) the receipt by GM of the Supplemental Ruling
         (as defined in the Hughes Distribution Agreement) and (z) the
         satisfaction of the conditions set forth in Section 6.1(b) of
         the Hughes Merger Agreement, or (iii) following the determina-
         tion of the Hughes Distribution Ratio, (A) GM shall fail to
         include in the Proxy/Consent Solicitation Statement the recom-
         mendation of the GM Board of Directors in favor of the GM
         Transactions as then set forth in the Hughes 


                                     - 11 -<PAGE>



         Distribution Agreement or (B) the Board of Directors of GM
         shall withdraw or modify in any adverse manner its approval or
         recommendation of the GM Transactions or fail to reaffirm such
         approval or recommendation upon Raytheon's request.

                   Section 5.2    Effect of Termination.  In the event
         of the termination of this Agreement pursuant to Section 5.1
         above, this Agreement shall become void and have no effect,
         without any liability on the part of either Party or its sub-
         sidiaries or their respective directors, officers or stockhold-
         ers, except as may be provided in Section 7.2 of the Hughes
         Merger Agreement.  Notwithstanding the foregoing, nothing in
         this Section 5.2 shall relieve either Party to this Agreement
         of liability for a willful breach of any provision of this
         Agreement. 

                   Section 5.3    Amendment.  This Agreement may be
         amended by the Parties hereto, by action taken or authorized by
         their respective Boards of Directors, at any time before or
         after adoption of the Hughes Merger Agreement by Raytheon
         Stockholders and before or after approval of the GM Transac-
         tions by GM's common stockholders, but after either such ap-
         proval or authorization, no amendment shall be made which by
         law requires further approval or authorization by the Raytheon
         Stockholders or the common stockholders of GM, as the case may
         be, without such further approval or authorization.  Notwith-
         standing the foregoing, this Agreement may not be amended ex-
         cept by an instrument in writing signed on behalf of each of
         the Parties hereto.

                   Section 5.4    Extension; Waiver.  At any time prior
         to the Effective Time, GM (with respect to Raytheon) and Ray-
         theon (with respect to GM) by action taken or authorized by
         their respective Boards of Directors, may, to the extent le-
         gally allowed, (a) extend the time for the performance of any
         of the obligations or other acts of such Party, (b) waive any
         inaccuracies in the representations and warranties contained
         herein or in any document delivered pursuant hereto and (c)
         waive compliance with any of the agreements or conditions con-
         tained herein.  Any agreement on the part of a Party hereto to
         any such extension or waiver shall be valid only if set forth
         in a written instrument signed on behalf of such Party.

         Warranties.  The representations and warranties made herein by
         the Parties hereto shall not survive the Effective Time.  This
         Section 6.1 shall not limit any covenant or agreement of the
         Parties hereto which by its terms contemplates performance af-
         ter the Effective Time or the termination of this Agreement.

         FOR IMMEDIATE RELEASE



                 RAYTHEON COMPANY AND HUGHES ELECTRONICS' DEFENSE
               BUSINESS TO MERGE, CREATING A $21 BILLION ENTERPRISE


            COMBINATION CREATES A WORLD LEADER IN DEFENSE ELECTRONICS


         NEW YORK, NY, JANUARY 16, 1997 --  Raytheon Company (NYSE:RTN)
         announced today that it has entered into definitive agreements
         with Hughes Electronics Corporation (NYSE:GMH) to bring about
         the merger of the Hughes Electronics defense operations (Hughes
         Aircraft) and Raytheon.  The combined company will be called
         Raytheon Company.

              The transaction is valued at $9.5 billion, comprised of
         approximately $5.1 billion in common stock and $4.4 billion in
         debt.  (See later discussion for the transaction specifics.)

              On a 1996 pro-forma basis, the combined company will have
         revenues of approximately $21 billion, over $13 billion of
         which will be in defense electronics.  The current backlog for
         the combined company will be approximately $23 billion, with
         defense electronics accounting for $18 billion.  This
         transaction, coupled with the recently announced acquisition of
         the Texas Instruments defense business, will result in slight
         dilution to the earnings of the combined company in 1997, as
         compared to the earnings of Raytheon on a stand-alone basis for
         the same period.  The transaction will be minimally accretive
         in 1998 and increasingly accretive thereafter.  The transaction
         is expected to close by mid-year.

              Dennis J. Picard, Raytheon's chairman and chief executive
         officer, said, "The people of Raytheon have always had the
         greatest respect for the technical expertise and management
         skills of the Hughes defense team.  The combination of the
         Hughes and Raytheon defense businesses will create a unique
         technology company and a world leader











                                        1<PAGE>







         in defense electronics. Together, our combined businesses will 
         have the critical mass needed to compete effectively in all of 
         our global markets. Raytheon will now offer an even broader 
         range of products and services to each of our customers, 
         outstanding returns to our shareholders, and a more secure and 
         promising future for our people."

              "It is clear that the end of the Cold War, and the
         resulting decline in the U.S. defense procurement budget, have
         brought about fundamental changes to the defense industry
         requiring continued consolidation.  The strategic combination
         of Raytheon, TI Defense and Hughes Defense enables us to
         address those changes head-on and to grow in the best segment
         of the defense business -- defense electronics."

              "The substantial synergies inherent in the combined
         businesses will ensure that our revenue and profitability
         objectives will be met, and that resources will be made
         available to pursue new technology opportunities in defense as
         well as in our commercial businesses."

              "In summary," Picard said, "we are truly creating another
         defense electronics powerhouse."

              C. Michael Armstrong, chairman and chief executive officer
         of Hughes Electronics, said, "For Hughes Aircraft to remain
         competitive in a shrinking market, there was a need to increase
         its participation in the industry consolidation.  Raytheon
         together with Hughes will create a much more competitive
         company that can better serve the defense market with
         leadership in systems and electronics."

              John C. Weaver, president of Hughes Aircraft, said, "Our
         two companies have worked together successfully on several
         ventures in the past, such as the Standard Missile Company and
         Medium Extended Air Defense System (MEADS).  That same spirit
         of cooperation will now propel us to greater growth and
         prosperity for our stakeholders than would have been possible
         individually."  Weaver will report directly to Mr. Picard as
         the president of Raytheon Hughes Systems, which will operate as
         a division of the combined company.










                                        2<PAGE>







              Upon completion of this transaction, and closing of the
         acquisition of Texas Instruments' Defense Systems & Electronics
         Group, announced on January 6, the combined company will have
         approximately 127,000 employees worldwide.  Raytheon's
         headquarters will be based in Lexington, Massachusetts.

              In connection with the merger, C. Michael Armstrong;
         Charles H. Noski, currently vice chairman and chief financial
         officer of Hughes Electronics; and an independent director of
         GM to be named later, will be members of the Board of Directors
         of the combined company.

              The transaction is subject to approval by Raytheon's
         stockholders, certain regulatory approvals (including Hart-
         Scott-Rodino antitrust review), approval by the holders of GM
         common stock, and the receipt by GM of rulings from the
         Internal Revenue Service relating to certain federal income tax
         consequences of the transaction.

         Transaction Summary

              Hughes Aircraft will be spun off to the holders of GM's
         $1-2/3 and Class H common stocks in a transaction intended to
         be tax-free.  In connection with the spin-off and subsequent
         merger, two classes of common stock will be created:  Class A
         common stock, which will be held by GM $1-2/3 and Class H
         stockholders after the spin-off and will be entirely held by
         the public; and Class B common stock.

              Immediately following the spin-off of Hughes Aircraft,
         Raytheon and Hughes Aircraft will merge.  In the merger,
         Raytheon stockholders will receive all of the Class B common
         stock of the combined company.  The Class B common stock will
         represent approximately 70 percent of the equity of the
         combined company, and the Class A Common stock will represent
         the remaining, approximately 30 percent.

              The merger terms provide that Hughes Aircraft's total debt
         will be adjusted to reflect variations in the market price of
         Raytheon stock, subject to specified limits, so that the two
         components of value will total $9.5 billion so long as such
         market price is between $44.42 and $54.29 per share.  The
         approximately $5.1 billion in common stock issued to the Class
         A stockholders is based upon the midpoint of this range.  The
         balance of the $9.5 billion transaction value will be made up
         of approximately $4.4 billion in Hughes Aircraft debt.

              In the election of directors to the combined company
         board, Class A common stock will have an 80.1 percent voting
         interest, and Class B common stock will have a 19.9 percent
         voting interest.  The board of directors will have staggered
         terms for directors.  Except as to voting rights for directors,
         each class will vote separately as to all other matters, and
         the Class A and Class B stock will have identical rights.  In a
         merger, acquisition or any other type of reorganization, Class
         A and Class B common stock must receive the same consideration.
