                   CONVERSION OF SHARES; MERGER CONSIDERATION

            2.1. Conversion of Shares. At the Effective Time, by virtue of the
Merger and without any action on the part of any of the parties hereto or any
holder of shares of Company Common Stock:

            (a) Common Stock of Hughes and GM. Each issued and outstanding share
of common stock, par value $1.00 per share, of Hughes shall remain outstanding
and shall be unchanged as a result of the Merger. The issued and outstanding
securities of GM shall remain outstanding and shall be unchanged as a result of
the Merger.

            (b) Cancellation of Treasury Shares and GM-Owned Shares. Each share
of Company Common Stock issued and outstanding immediately prior to the
Effective Time (each, a "Share") that is owned by the Company or any subsidiary
of the Company, or by GM or Hughes (other than Shares in trust accounts, managed
accounts, custodial accounts and the like that are beneficially owned by third
parties) shall automatically be cancelled and shall cease to exist, and no
consideration shall be delivered or deliverable in exchange therefor.

            (c) Common Stock of the Company. Each Share, other than Shares to be
cancelled in accordance with Section 2.1(b) and any Dissenting Shares (as
defined in Section 2.5), shall be converted, in accordance with Section 2.2(a),
into the right to receive the Merger Consideration (as defined in Section
2.2(a)) and shall cease to be outstanding and shall automatically be canceled
and shall cease to exist, and each holder of a certificate previously evidencing
any such Shares (each, a "Company Certificate") shall cease to have any rights
with respect thereto, except the right to receive, upon the surrender of such
Company Certificate in accordance with the provisions of Section 2.3, the Merger
Consideration multiplied by the number of Shares previously evidenced by such
Company Certificate.

            2.2.  Merger Consideration.

            (a) Merger Consideration. Except as otherwise provided in Section
2.4 and subject to Section 2.5, the term "Merger Consideration" shall mean, at
the election of each holder of Shares, which election shall be available on a
share-by-share basis, one of the following:

                              (i) for each Share with respect to which an
            election to receive cash has been effectively made or deemed made
            pursuant to Section 2.3 and not revoked (a "Cash Election"), the
            right to receive an amount in cash, without interest, equal to the
            Share Value (the "Cash Consideration Per Share"); or

                              (ii) for each Share with respect to which an
            election to receive shares of Acquiror Stock has been effectively
            made pursuant to Section 2.3 and not revoked (a "Stock Election"),
            the right to receive a fractional interest

                                     3
<PAGE>
            in a share of Acquiror Stock equal to the Exchange Ratio (as defined
            in Section 2.2(b)) (the "Stock Consideration Per Share"), subject to
            Section 2.3(h).

            For purposes of this Agreement:

                              (1) "Acquiror Stock" shall mean the Class H Common
            Stock of GM, par value $0.10 per share;

                              (2) "Share Value" shall mean the product of (x)
            the Exchange Ratio and (y) the 20-Day Average Price; and

                              (3) "20-Day Average Price" shall mean the average
            (rounded to nearest 1/10,000, or if there shall not be a nearest
            1/10,000, to the next highest 1/10,000) of the volume weighted
            averages (rounded to the nearest 1/10,000, or if there shall not be
            a nearest 1/10,000, to the next highest 1/10,000) of the trading
            prices of the Acquiror Stock on the New York Stock Exchange, Inc.
            (the "NYSE") as reported by Bloomberg Financial Markets (or such
            other source as the parties shall agree in writing) for each of the
            20 consecutive trading days ending on and including the second
            trading day prior to the Closing Date;

            (b)   Exchange Ratio.

                              (i) The Exchange Ratio shall be determined in the
            following manner, subject to reduction pursuant to Section 2(b)(ii):

                  (A) If the 20-Day Average Price is less than or equal to
            $47.6821 (the "Cap Price"), and greater than or equal to $27.8146
            (the "Floor Price"), the Exchange Ratio shall be equal to 0.3775.

                  (B) If the 20-Day Average Price is greater than the Cap Price,
            the Exchange Ratio shall be equal to the quotient obtained by
            dividing $18.00 by the 20-Day Average Price (such quotient shall be
            rounded to the nearest 1/10,000, or if there shall not be a nearest
            1/10,000 to the next lowest 1/10,000).

                  (C) If the 20-Day Average Price is less than the Floor Price,
            the Exchange Ratio shall be equal to the quotient obtained by
            dividing (x) the lower of (1) $10.50 and (2) the Adjusted Price (as
            defined in Section 2.4(e)) by (y) the 20-Day Average Price (such
            quotient shall be rounded to the nearest 1/10,000, or if there shall
            not be a nearest 1/10,000, to the next highest 1/10,000).

                              (ii) The Exchange Ratio shall be reduced by the
            amount determined by:


                                     4
<PAGE>
                  (A) first, dividing the Excess Termination Amount by the
            number of Shares (such quotient, the "Excess Termination Amount Per
            Share"), and

                  (B) then, dividing the Excess Termination Amount Per Share by
            the 20-Day Average Price (the resulting quotient shall be rounded to
            the nearest 1/10,000 or, if there shall not be a nearest 1/10,000,
            to the next highest 1/10,000).

            The "Excess Termination Amount" shall be the sum of (x) the amount,
            if any, by which the payments made or required to be made by the
            Company or any of its subsidiaries after the date hereof arising out
            of or relating to the termination of the contract identified on
            Section 2.2(b)(ii)(x) of the Acquiror Disclosure Schedule exceed the
            Termination Amount in respect thereof set forth therein, and (y) the
            amount, if any, by which the payments made or required to be made by
            the Company or any of its subsidiaries after the date hereof arising
            out of or relating to the termination of the contract identified in
            Section 2.2(b)(ii)(y) of the Acquiror Disclosure Schedule exceed the
            Termination Amount in respect thereof set forth in therein.

                              (iii) If between the date of this Agreement and
            the Effective Time, the outstanding shares of Acquiror Stock or
            Company Common Stock shall have been changed into a different number
            of shares or a different class, by reason of any stock dividend,
            subdivision, reclassification, recapitalization, rights offering,
            split, combination or exchange of shares, the Exchange Ratio
            correspondingly shall be adjusted to the extent warranted to reflect
            such stock dividend, subdivision, reclassification,
            recapitalization, rights offering, split, combination or exchange of
            shares.

            2.3.  Stock and Cash Elections; Exchange Fund.

            (a) Right to Elect. Each Person who, at the Effective Time, is a
record holder of Shares (other than holders of Shares to be cancelled as set
forth in Section 2.1(b) or Shares subject to Section 2.5) shall have the right
to submit an Election Form (as defined in Section 2.3(b)) specifying the number
of Shares that such Person desires to have converted into the right to receive,
subject to Section 2.4, (i) the Stock Consideration Per Share pursuant to the
Stock Election and (ii) the Cash Consideration Per Share pursuant to the Cash
Election.

            (b) Letter of Transmittal and Election Form. As soon as reasonably
practicable after the Effective Time, a bank or trust company to be designated
by GM (the "Exchange Agent") shall mail to each holder of record of Shares
immediately prior to the Effective Time (excluding any Shares to be cancelled
pursuant to Section 2.1(b) or subject to Section 2.5) (i) a letter of
transmittal (the "Letter of Transmittal") which shall specify that delivery
shall be effected, and risk of loss and title to the Company Certificates shall
pass, only upon delivery of such Company Certificates to the Exchange Agent and
shall be in such form and have such other provisions as GM shall reasonably
specify, (ii) an election form (the "Election Form") providing for such holders
to make the Cash Election or the Stock

                                     5
<PAGE>
Election and (iii) instructions for use in effecting the surrender of the
Company Certificates in exchange for the Merger Consideration with respect to
the Shares formerly represented thereby. The Election Form shall include
information as to the Share Value and the Exchange Ratio. As of the Election
Deadline (as hereinafter defined), to the extent that a holder of Shares shall
not have submitted to the Exchange Agent an effective, properly completed
Election Form with respect to all or certain of the Shares held by such holder
or shall have properly revoked and not properly submitted to the Exchange Agent
a subsequent Election Form with respect to all or certain of the Shares, such
holder shall be deemed to have made the Cash Election with respect to such
Shares.

            (c) Election Deadline and Allocation Determination. Any Stock
Election shall have been validly made only if the Exchange Agent shall have
received by 5:00 p.m. New York, New York time on a date (the "Election
Deadline") to be mutually agreed upon by Hughes and the Company (which date
shall not be later than the twentieth (20th) business day after the Effective
Time), an Election Form properly completed and executed (with the signature or
signatures thereof guaranteed to the extent required by the Election Form) by
such holder accompanied by such holder's Company Certificates, or by an
appropriate guarantee of delivery of such Company Certificates from a member of
any registered national securities exchange or of the National Association of
Securities Dealers, Inc. or a commercial bank or trust company in the United
States as set forth in such Election Form. Any holder of Shares (other than a
holder who has submitted an irrevocable election) who has made an election by
submitting an Election Form to the Exchange Agent may at any time prior to the
Election Deadline change such holder's election by submitting a revised Election
Form, properly completed and signed that is received by the Exchange Agent prior
to the Election Deadline. Any holder of Shares may at any time prior to the
Election Deadline revoke such holder's election by written notice to the
Exchange Agent received by the close of business on the day prior to the
Election Deadline. As soon as practicable after the Election Deadline, the
Exchange Agent shall, subject to Section 2.4, determine the allocation of the
cash portion of the Merger Consideration and the stock portion of the Merger
Consideration and shall notify GM, Hughes and HBI (as a representative of the
shareholders of the Company) of its determination (the "Allocation
Determination").

            (d) Deposit of Merger Consideration. Promptly after the Allocation
Determination, Hughes shall deposit with the Exchange Agent, for the benefit of
the holders of Shares for exchange in accordance with this Article 2, (i) cash
in an amount sufficient to pay the aggregate Merger Consideration that shall
take the form of cash and (ii) certificates or other evidence representing the
aggregate Merger Consideration that shall take the form of shares of Acquiror
Stock ("Acquiror Certificates"; the cash and certificates or other evidence
deposited pursuant to clauses (i) and (ii) being hereinafter referred to as the
"Exchange Fund"). The Acquiror Stock into which Company Common Stock shall be
converted pursuant to the Merger shall be deemed to have been issued at the
Effective Time for purposes of entitlement to dividends declared, if any, after
the Effective Time. In connection with the issuance of shares of Acquiror Stock
pursuant to this Agreement and the contribution by GM to the capital of Hughes
of cash in an amount no less than the fair market value of such shares, GM's
Board of Directors shall, in accordance with paragraph (a)(4) of Division I of
Article Fourth of GM's Amended and Restated Certificate of Incorporation, as
amended, make an appropriate adjustment to the denominator of the


                                     6
<PAGE>
fraction used to determine the "Available Separate Consolidated Net Income of
Hughes," as defined therein.

            (e) Surrender of Company Certificates. Upon surrender of a Company
Certificate to the Exchange Agent, together with the Letter of Transmittal, duly
executed, and such other documents as Hughes or the Exchange Agent shall
reasonably request, the holder of such Company Certificate shall be entitled to
receive, promptly after the Election Deadline in exchange therefor, (i) a
certified or bank cashier's check in the amount equal to the aggregate amount of
the Merger Consideration consisting of cash which such holder has the right to
receive pursuant to the provisions of this Article 2 (including any cash in lieu
of fractional shares of Acquiror Stock pursuant to Section 2.3(h)) and (ii)
Acquiror Certificates representing the Acquiror Stock, if any, which such holder
has the right to receive (in each case without interest and less the amount of
any required withholding taxes, if any, in accordance with Section 2.3(k)).

            (f) Rules Governing Exchange. Hughes, in consultation with the
Company prior to the Effective Time, shall have the right to make reasonable
rules, not inconsistent with the terms of this Agreement, governing the validity
of the Election Forms, the manner and extent to which Cash Elections or Stock
Elections are to be taken into account in making the determinations prescribed
by Section 2.4, the issuance and delivery of certificates for, or other evidence
of, Acquiror Stock, and the payment of the Cash Consideration Per Share.

            (g) Distributions With Respect to Unexchanged Shares of Acquiror
Stock. No dividends or other distributions with respect to shares of Acquiror
Stock, with a record date after the Effective Time, shall be paid to the holder
of any unsurrendered Company Certificate with respect to the shares of Acquiror
Stock they are entitled to receive until such Company Certificate is surrendered
by such holder.

            (h) Fractional Shares. No fraction of a share of Acquiror Stock
shall be issued in the Merger. In lieu of any such fractional shares, each
holder of Shares entitled to receive a fraction of a share of Acquiror Stock in
the Merger, upon surrender of a Company Certificate for exchange pursuant to
this Section 2.3, shall be paid in lieu thereof an amount in cash (without
interest), rounded to the nearest cent, determined by multiplying (x) the Share
Value by (y) the fractional interest in Acquiror Stock to which such holder
would otherwise be entitled (after aggregating all shares of Acquiror Stock
which such holder is entitled to receive pursuant to this Article 2).

            (i) Termination of Exchange Fund. Any portion of the Exchange Fund
which remains undistributed to the former holders of Shares for twelve (12)
months after the Effective Time shall be delivered to Hughes, upon demand, and
any former holders of Shares who have not theretofore complied with this Article
2 shall thereafter look only to Hughes for the Merger Consideration to which
they are entitled pursuant to this Article 2.

            (j) No Liability. None of GM, Hughes or the Company shall be liable
to any former holder of Shares for any Merger Consideration from the Exchange
Fund delivered to a public official pursuant to any applicable abandoned
property, escheat or similar law.

 
                                    7
<PAGE>
            (k) Withholding Rights. GM, Hughes and the Exchange Agent shall be
entitled to deduct and withhold, from the consideration otherwise payable
pursuant to this Agreement to any former holder of Shares, such amounts as GM,
Hughes, the Company (or any subsidiary thereof) or the Exchange Agent is
required to deduct and withhold with respect to the making of such payment under
the Code or any provision of state, local or foreign tax law. To the extent that
amounts are so withheld by GM, Hughes or the Exchange Agent, such withheld
amounts shall be treated for all purposes of this Agreement as having been paid
to the former holder of the Shares in respect of which such deduction and
withholding was made by GM, Hughes or the Exchange Agent.

            2.4.  Prorations.

            (a) Requested Cash Amount Not in Excess of Cash Cap and Not Below
Minimum Cash Amount. If the Requested Cash Amount equals or exceeds the Minimum
Cash Amount and does not exceed the Cash Cap, the Merger Consideration shall be
issued and paid in the manner set forth in Section 2.2, unless the 20-Day
Average Price is less than the Floor Price and the Acquiror Stock to be issued
pursuant to this Agreement would exceed the Acquiror Share Cap, in which case
the adjustments set forth in Section 2.4(d) shall be made.

            (b) Requested Cash Amount in Excess of Cash Cap. If the Requested
Cash Amount exceeds the Cash Cap, each holder who makes or is deemed to have
made a Cash Election pursuant to Section 2.3 shall receive, for each Share for
which a Cash Election has been made or deemed made, Merger Consideration
consisting of:

                              (i) cash in an amount equal to the product of the
            Share Value and a fraction, (A) the numerator of which is the Cash
            Cap and (B) the denominator of which is the Requested Cash Amount;
            and

                              (ii) a fractional interest in a share of Acquiror
            Stock equal to a fraction, (A) the numerator of which is equal to
            the Share Value minus the amount of cash payable pursuant to clause
            (i) of this Section 2.4(b) and (B) the denominator of which is the
            20-Day Average Price.

            (c) Requested Cash Amount Below Minimum Cash Amount. If the
Requested Cash Amount is less than the Minimum Cash Amount and the 20-Day
Average Price equals or exceeds the Floor Price, each holder making a Stock
Election shall receive, for each Share for which a Stock Election has been made,
Merger Consideration consisting of:

                              (i) cash in an amount equal to the quotient
            obtained by dividing (A) the excess of the Minimum Cash Amount over
            the Requested Cash Amount by (B) the number of Shares for which such
            Stock Elections have been made; and

                              (ii) a fractional interest in a share of Acquiror
            Stock equal to a fraction, (A) the numerator of which is equal to
            the excess of the Share Value


                                     8
<PAGE>
            over the amount of cash payable pursuant to clause (i) of this
            Section 2.4(c) and (B) the denominator of which is the 20-Day
            Average Price.

            (d) Adjustments Required if 20-Day Average Price Is Less Than Floor
Price. If (A) the 20-Day Average Price is less than the Floor Price, (B) the
Requested Cash Amount does not exceed the Cash Cap, and (C) the number of shares
of Acquiror Stock that would be issuable pursuant to this Agreement would, but
for this Section 2.4(d), exceed the Acquiror Share Cap, then each holder making
a Stock Election shall receive, for each Share for which a Stock Election has
been made, Merger Consideration consisting of:

                                    (x) a fractional interest in a share of
      Acquiror Stock equal to the product of the Stock Consideration Per Share
      and a fraction, (I) the numerator of which is the Acquiror Share Cap and
      (II) the denominator of which is the total number of shares of Acquiror
      Stock that, but for Section 2.4, would have been issuable to all holders
      of Shares pursuant to this Agreement, and

                                    (y) an amount of cash equal to the excess of
      (I) the Share Value over (II) the product of (a) the fractional interest
      in a share of Acquiror Stock to which such holder shall be entitled
      pursuant to clause (x) of this Section 2.4(d) and (b) the 20-Day Average
      Price.

            (e) Certain Definitions. For purposes of this Agreement:

                              (i) "Acquiror Share Cap" shall mean a number equal
            to seventy percent (70%) of the product of the number of Shares and
            0.3775.

                              (ii) "Adjusted Price" shall mean an amount equal
            to the quotient obtained by dividing (1) an amount equal to two
            hundred percent (200%) of the product of the Acquiror Share Cap and
            the 20-Day Average Price by (2) the number of Shares.

                              (iii) "Cash Cap" shall mean an amount of cash 
            determined as follows:

                                    (A) If the 20-Day Average Price equals or
      exceeds the Floor Price, the Cash Cap shall be equal to fifty percent
      (50%) of the product of (1) the Exchange Ratio, and (2) the Closing Date
      Price, and (3) the number of Shares.

                                    (B) If the 20-Day Average Price is less than
      the Floor Price, the Cash Cap shall be equal to the lesser of (1) the
      amount described in clause (A) of this Section 2.4(e)(iii) and (2) the
      product of (X) the Acquiror Share Cap and (Y) the Closing Date Price.

                                    (C) Notwithstanding anything to the contrary
      contained in this Agreement, if, based on the Merger Consideration payable
      pursuant to this Agreement, the tax opinions referred to in Sections
      6.2(e) and 6.3(h) hereof

                                     9
<PAGE>
            cannot be delivered as a result of the Merger potentially failing to
            satisfy continuity of interest requirements under applicable federal
            income tax principles relating to reorganizations under 368(a) of
            the Code (as reasonably determined by Weil, Gotshal & Manges LLP, in
            consultation with Leonard, Street and Deinard Professional
            Association, such determination to be made (x) taking into account
            Dissenting Shares and cash issued in lieu of fractional shares, if
            any, (y) using the Closing Date Price as the measure of value of the
            shares of Acquiror Stock issued as Merger Consideration and (z) on
            the basis that the total value of such Acquiror Stock issued as
            Merger Consideration must represent no less than forty-five percent
            (45%) of the total consideration issued and to be issued in the
            Merger to all holders of Shares), then the Cash Cap shall be reduced
            to the extent necessary to enable the tax opinions to be rendered.

                              (iv) "Closing Date Price" shall mean the per share
            closing price of the Acquiror Stock on the NYSE as of the Closing
            Date.

                              (v) "Minimum Cash Amount" shall mean an amount
            equal to the lesser of (A) 30% of the product of the Share Value and
            the number of Shares and (B) the Cash Cap.

                              (vi) "Requested Cash Amount" shall mean the
            aggregate amount of cash that would be payable with respect to all
            Shares for which Cash Elections have been made or deemed made
            pursuant to Section 2.3 or 2.5, before giving effect to Section 2.4.

            (f) Application of Cash and Share Limitations. The foregoing
provisions of this Article 2 are not intended to, and shall not be applied so as
to, result in:

                              (i) the issuance of an aggregate number of shares
            of Acquiror Stock in excess of the Acquiror Share Cap;

                              (ii) the payment of an aggregate amount of cash in
            excess of the Cash Cap;

                              (iii) the receipt by a holder of Merger
            Consideration per Share having an aggregate value (with Merger
            Consideration in the form of Acquiror Stock valued for this purpose
            at the 20-Day Average Price) less than the Share Value unless both
            (x) the aggregate number of shares of Acquiror Stock to be issued is
            equal to the Acquiror Share Cap, and (y) the aggregate amount of
            cash to be paid is equal to the product of (1) the Acquiror Share
            Cap and (2) the Closing Date Price; or

                              (iv) the receipt by a holder making a Cash
            Election of a value per Share which is different from the value per
            Share received by a holder making a Stock Election (with Acquiror
            Stock valued for this purpose at the 20-Day Average Price).

            2.5. Dissenting Shares. Notwithstanding anything in this Agreement
to the contrary, Shares held by a holder (if any) who has the right to exercise
dissenters' rights under Section 302A.471 and Section 302A.473 of the MBCA, or
any successor provisions (the "Dissenters' Rights Statute") and who shall have
filed with the Company, prior to the vote by the shareholders of the Company on
this Agreement and the Merger, a notice of intent to demand payment of the fair
value of such Shares in accordance with the Dissenters' Rights Statute and shall
not have voted to approve this Agreement and the Merger ("Dissenting Shares")
shall not be converted into a right to receive the Merger Consideration, unless
such holder fails to perfect or otherwise loses such holder's right to exercise
such holder's dissenters' rights with respect to such Shares, if any. If, before
or after the Effective Time, such holder fails to perfect or loses any such
right to exercise such holder's dissenters' rights with respect to such Shares,
each such Share of such holder shall be treated as a Share that had been
converted as of the Effective Time into the right to receive the Merger
Consideration and such holder shall be deemed to have made the Cash Election. At
the Effective Time, any holder of Dissenting Shares shall cease to have any
rights with respect thereto, except the rights provided in the Dissenters'
Rights Statute and as provided in the immediately preceding sentence. The
Company shall give prompt notice to Hughes of any notices of intent to demand
fair value of Shares in accordance with the Dissenters' Rights Statute received
by the Company, and Hughes shall have the right to participate in and direct all
negotiations and proceedings with respect to such demands. The Company shall
not, except with the prior written consent of Hughes, make any payment with
respect to, or settle or offer to settle, any such demands.

            2.6. Stock Options. The Company may elect to take all such action
necessary to cause each Company Stock Option (as defined in Section 3.2(a)),
which is outstanding and unexercised immediately prior to the Effective Time, to
become vested as of the Effective Time. Hughes shall pay each holder of any
Company Stock Option, with respect to each Share subject to such Company Stock
Option, an amount in cash equal to the excess of the Share Value over the
exercise price per Share of such Company Stock Option, less all applicable
withholding taxes. All Company Stock Options and all Company stock option plans,
arrangements or agreements shall be terminated thereafter as of the Effective
Time.

                                  ARTICLE 3

                REPRESENTATIONS AND WARRANTIES OF THE COMPANY

            The Company hereby represents and warrants to each of GM and Hughes
as follows:

            3.1.  Organization and Qualification.

            (a) The Company and each of its subsidiaries (as defined in Section
3.1(b)) is a corporation duly organized, validly existing and in good standing
under the laws of the jurisdiction of its incorporation or organization and has
all requisite corporate power and authority to own, lease and operate its
properties and to carry on its businesses as now being conducted, except where
the failure to be so organized, existing and in good standing or to


                                     11
<PAGE>
have such power and authority would not have or constitute a Material Adverse
Effect (as defined below) on the Company. When used in connection with any party
to this Agreement, the term "Material Adverse Effect" means (i) a material
adverse effect, or any development that results in a material adverse effect, on
the business, operations, financial performance or prospects of such party and
its subsidiaries, taken as whole, or (ii) an event, change, effect or
development that may materially impair or delay the ability of such party to
consummate the transactions contemplated hereby; provided, however, that effects
or developments arising from (A) general economic conditions affecting
participants in the multichannel entertainment distribution industry, (B)
inactions of the Company resulting from Hughes' refusal to provide its consent
pursuant to Section 5.1 of this Agreement or (C) actions which the Company is
required to take pursuant to this Agreement, shall not constitute a Material
Adverse Effect.

            (b) Except as set forth in Section 3.1(b) of the Disclosure Schedule
previously delivered by the Company to GM (the "Company Disclosure Schedule"),
the Company has no subsidiaries and does not own, directly or indirectly,
beneficially or of record, any shares of capital stock or other security of any
other entity or any other investment in any other entity. The term "subsidiary"
shall mean, when used with reference to any party to this Agreement, any entity
more than fifty percent (50%) of either the outstanding voting securities or the
value of the outstanding equity securities or interests (including membership
interests) of which are owned directly or indirectly by such party.

            (c) The Company and each of its subsidiaries is duly qualified or
licensed and in good standing to do business in each jurisdiction in which the
property owned, leased or operated by it or the nature of the business conducted
by it makes such qualification or licensing necessary, except in such
jurisdictions where the failure to be so duly qualified or licensed and in good
standing would not, individually or in the aggregate, have a Material Adverse
Effect on the Company.

            (d) The Company has heretofore delivered to Hughes accurate and
complete copies of the articles of incorporation and by-laws, as currently in
effect, of the Company and each of its subsidiaries.

            3.2.  Capitalization of the Company and Its Subsidiaries.

            (a) The authorized capital stock of the Company consists of: (i)
100,000,000 shares of Common Stock, par value $.0001 per share (the "Common
Stock"), of which, as of December 1, 1998, 60,868,825 shares were issued and
outstanding and no shares were held in treasury, (ii) 500,000,000 shares of
Class A Common Stock, par value $.0001 per Share (the "Class A Common Stock";
and collectively with the Common Stock, the "Company Common Stock"), of which,
as of December 1, 1998, 28,941,950 shares were issued and outstanding and no
shares were held in treasury and (iii) 50,000,000 shares of Preferred Stock, par
value $.01 per share, no shares of which are issued and outstanding. All of the
issued and outstanding shares of Company Common Stock have been validly issued,
and are fully paid, nonassessable and free of preemptive rights. As of December
1, 1998, 713,400 shares of Class A Common Stock were reserved for issuance and
issuable upon or otherwise deliverable in connection with the exercise of
outstanding

                                     12
<PAGE>
options granted by the Company to purchase shares of Class A Common Stock (the
"Company Stock Options") issued pursuant to the Company stock option plans
listed in Section 3.2(a) of the Company Disclosure Schedule. Since December 1,
1998, no shares of the Company's capital stock have been issued other than
pursuant to the exercise of Company Stock Options already in existence on such
date and, since December 1, 1998, no Company Stock Options have been granted.
Except as set forth above in this Section 3.2(a), as of the date hereof, there
are outstanding (i) no shares of capital stock or other voting securities of the
Company, (ii) no securities of the Company or its subsidiaries convertible into
or exchangeable for shares of capital stock or voting securities of the Company,
(iii) no options or other rights to acquire from the Company or its
subsidiaries, and no obligations of the Company or its subsidiaries to issue,
any capital stock, voting securities or securities convertible into or
exchangeable for capital stock or voting securities of the Company, and (iv) no
equity equivalents, or interests in the ownership or earnings, of the Company or
its subsidiaries or other similar rights (including stock appreciation rights)
(collectively, "Company Securities"). There are no outstanding obligations of
the Company or its subsidiaries to repurchase, redeem or otherwise acquire any
Company Securities. Except as set forth in Section 3.2(a) of the Company
Disclosure Schedule, there are no shareholder agreements, voting trusts or other
agreements or understandings to which the Company is a party or to which it is
bound relating to the voting of any shares of capital stock of the Company.

            (b) Except as set forth in Section 3.2(b) of the Company Disclosure
Schedule, all of the outstanding capital stock of the Company's subsidiaries is
owned by the Company, directly or indirectly, free and clear of any Lien (as
defined below) or any other limitation or restriction (including any restriction
on the right to vote or sell the same, except as may be provided as a matter of
law). There are no securities of the Company or its subsidiaries convertible
into or exchangeable for, no options or other rights to acquire from the Company
or its subsidiaries, and no other contract, understanding, arrangement or
obligation (whether or not contingent) providing for the issuance or sale,
directly or indirectly of, any capital stock or other ownership interests in, or
any other securities of, any subsidiary of the Company. There are no outstanding
contractual obligations of the Company or its subsidiaries to repurchase, redeem
or otherwise acquire any outstanding shares of capital stock or other ownership
interests in any subsidiary of the Company. For purposes of this Agreement,
"Lien" means, with respect to any asset (including, without limitation, any
security) any mortgage, lien, pledge, charge, security interest or encumbrance
of any kind in respect of such asset.

            3.3.  Authority Relative to This Agreement.

            (a) The Company has all necessary corporate power and authority to
execute and deliver this Agreement and to consummate the transactions
contemplated hereby. The execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby have been duly and validly
authorized and approved by the Board of Directors of the Company (the "Company
Board") and the Statutory Committee and no other corporate proceedings on the
part of the Company are necessary to authorize this Agreement or to consummate
the transactions contemplated hereby (other than, with respect to the Merger,
the approval and adoption of this Agreement by the holders of a majority of the
voting power of the then outstanding shares of Company Common Stock). This
Agreement has been duly and validly executed and delivered by the Company and
constitutes a valid, legal and binding agreement of the Company, enforceable
against the Company in accordance with its terms.

            (b) The Company Board has, by unanimous vote of those present, duly
and validly approved, and taken all corporate actions required to be taken by
the Company Board for the consummation of the transactions, including the
Merger, contemplated hereby and by the Shareholders Agreement and resolved to
recommend that the shareholders of the Company approve and adopt this Agreement.
The Statutory Committee has been duly formed pursuant to Section 302A.673,
subd.1, and has duly and validly authorized and approved this Agreement, the
Merger and the Shareholders Agreement and the consummation of the transactions
contemplated by this Agreement and the Shareholders Agreement. The action of the
Statutory Committee in approving this Agreement and the transactions
contemplated hereby, including the Merger, and in approving the Shareholders
Agreement and the transactions contemplated thereby, is sufficient to render
inapplicable to the Merger, this Agreement, and the transactions contemplated by
the Shareholders Agreement, the provisions of Sections 302A.673 and 302A.675 of
the MBCA and no Minnesota or other State takeover statute or similar statute or
regulation applies to the Merger, this Agreement, the Shareholders Agreement, or
any of the transactions contemplated hereby or thereby.

            3.4.  SEC Reports; Financial Statements.

            (a) The Company has filed all required forms, reports and documents
with the Securities and Exchange Commission (the "SEC") since February 6, 1996
(the "Company SEC Reports"), each of which has complied in all material respects
with all applicable requirements of the Securities Act and the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), each as in effect on the
dates such forms, reports and documents were filed. None of the Company SEC
Reports, including, without limitation, any financial statements or schedules
included or incorporated by reference therein, contained, when filed, any untrue
statement of a material fact or omitted to state a material fact required to be
stated or incorporated by reference therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading. The consolidated financial statements of the Company included in
the Company SEC Reports complied as to form in all material respects with
applicable accounting requirements and the published rules and regulations of
the SEC with respect thereto and fairly present, in conformity with United
States generally accepted accounting principles ("GAAP") applied on a consistent
basis

                                     14
<PAGE>
(except as may be indicated in the notes thereto), the consolidated financial
position of the Company and its consolidated subsidiaries as of the dates
thereof and their consolidated results of operations and changes in financial
position for the periods then ended (subject, in the case of the unaudited
interim financial statements, to (A) normal year-end adjustments and (B) any
other adjustments described in the Company SEC Reports filed prior to the date
of this Agreement (the "Filed Company SEC Reports")).

            (b) The Company has heretofore made available to GM a complete and
correct copy of any material amendments or modifications, which have not yet
been filed with the SEC, to agreements, documents or other instruments which
previously had been filed by the Company with the SEC pursuant to the Exchange
Act.

            3.5.  Information Supplied.

            (a) None of the information supplied or to be supplied by the
Company for inclusion or incorporation by reference in the registration
statement on Form S-4 to be filed with the SEC by GM in connection with the
issuance of shares of Acquiror Stock in the Merger, including the prospectus
contained therein and any amendment thereof or supplement thereto (the "S-4")
will, at the time the S-4 is filed with the SEC and at the time it becomes
effective under the Securities Act, contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein not misleading. If at any time prior to
the Effective Time, any event with respect to the Company, its officers and
directors or any of its subsidiaries should occur which is required to be
described in the S-4, the Company shall promptly so advise Hughes.

            (b) The proxy statement relating to the meeting of the Company's
shareholders to be held in connection with the Merger, including any amendment
thereof or supplement thereto (the "Proxy Statement") will not, at the date
mailed to shareholders of the Company and at the times of the meeting of
shareholders of the Company to be held in connection with the Merger, 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 will comply as to form in all material respects
with the provisions of the Exchange Act and the rules and regulations
thereunder.

            3.6. Consents and Approvals; No Violations. Except for filings,
permits, authorizations, consents and approvals as may be required under, and
other applicable requirements of, the Securities Act, the Exchange Act, state
securities or blue sky laws, the Hart-Scott-Rodino Antitrust Improvements Act of
1976, as amended (the "HSR Act"), the Communications Act of 1934, as amended,
and the rules and regulations promulgated thereunder (the "Communications Act"),
the filing and recordation of a certificate of merger as required by the DGCL,
the filing of articles of merger as required by the MBCA, and as otherwise set
forth in Section 3.6 of the Company Disclosure Schedule, no filing with or
notice to, and no permit, authorization, consent or approval of, any court or
tribunal or administrative, governmental or regulatory body, agency or authority
(a "Governmental Entity") is necessary for the execution and delivery by the
Company of this Agreement or the consummation by the Company of the transactions
contemplated hereby, except where the


                                     15
<PAGE>
failure to obtain such permits, authorizations, consents or approvals or to make
such filings or give such notice would not, individually or in the aggregate,
have a Material Adverse Effect on the Company. Except as set forth in Section
3.6 to the Company Disclosure Schedule, neither the execution, delivery and
performance of this Agreement by the Company nor the consummation by the Company
of the transactions contemplated hereby will (i) conflict with or result in any
breach of any provision of the respective certificate or articles of
incorporation or bylaws (or similar governing documents) of the Company or any
of its subsidiaries, (ii) result in a violation or breach of, or constitute
(with or without due notice or lapse of time or both) a default (or give rise to
any right of termination, amendment, cancellation or acceleration or Lien)
under, any of the terms, conditions or provisions of any note, bond, mortgage,
indenture, lease, license, contract, agreement or other instrument or obligation
to which the Company or any of its subsidiaries is a party or by which any of
them or any of their respective properties or assets may be bound, or (iii)
violate any order, writ, injunction, decree, law, statute, rule or regulation
applicable to the Company or any of its subsidiaries or any of their respective
properties or assets, except in the case of (ii) or (iii) for violations,
breaches or defaults which would not, individually or in the aggregate, have a
Material Adverse Effect on the Company. Except as set forth in Section 3.6 of
the Company Disclosure Schedule, neither the execution, delivery and performance
of this Agreement by the Company, nor the consummation by the Company of the
transactions contemplated hereby, will require any consent or approval pursuant
to any material programming agreement, software license or billing/customer
service agreement binding on the Company. No rights of first refusal or first
offer, preemptive rights or similar rights of participation are applicable to
the transactions contemplated by this Agreement or the Shareholders Agreement.

            3.7. No Default. None of the Company or its subsidiaries is in
default or violation (and no event has occurred which with or without due notice
or the lapse of time or both would constitute a default or violation) of any
term, condition or provision of (i) its certificate or articles of incorporation
or bylaws (or similar governing documents), (ii) any note, bond, mortgage,
indenture, lease, license, contract, agreement or other instrument or obligation
to which the Company or any of its subsidiaries is now a party or by which any
of them or any of their respective properties or assets may be bound or (iii)
any order, writ, injunction, decree, law, statute, rule or regulation applicable
to the Company, its subsidiaries or any of their respective properties or
assets, except in the case of (ii) or (iii) for violations, breaches or defaults
which would not, individually or in the aggregate, have a Material Adverse
Effect on the Company.

            3.8. No Undisclosed Liabilities; Absence of Changes. Except as and
to the extent disclosed by the Company in the Filed Company SEC Reports or as
disclosed in Section 3.8 of the Company Disclosure Schedule, since January 1,
1998, (a) neither the Company nor its subsidiaries has incurred any liabilities
or obligations of any nature, whether or not accrued, contingent or otherwise,
and whether due or to become due or asserted or unasserted, which would,
individually or in the aggregate, have a Material Adverse Effect on the Company,
(b) except as contemplated by this Agreement, the business of the Company and
its subsidiaries has been carried on in all material respects in the ordinary
course consistent with past practices, (c) the Company has not paid any dividend
or distribution in respect of, or redeemed or repurchased any of, its capital
stock or other equity

                                     16
<PAGE>
securities, including securities directly or indirectly convertible into or
exercisable or exchangeable for any of its capital stock or other equity
securities, (d) the Company has not entered into or consummated any transaction
with any officer, director or affiliate of the Company or any person known by
the Company to be an affiliate of any of them and (e) except as required by
GAAP, the Company has not changed its methods of accounting (either for
financial accounting or tax purposes).

            3.9. Litigation. Except as disclosed by the Company in the Filed
Company SEC Reports, as disclosed in Section 3.9 of the Company Disclosure
Schedule, or as would not, individually or in the aggregate, have a Material
Adverse Effect on the Company, (i) there is no suit, claim, action, proceeding
or investigation pending or, to the knowledge of the Company, threatened against
the Company or any of its subsidiaries or any of their respective properties or
assets and (ii) none of the Company or its subsidiaries is subject to any
outstanding order, writ, injunction or decree.

            3.10. Compliance with Applicable Law. Except as disclosed by the

lawful conduct of their respective businesses (the "Company Permits"), (ii) the
Company and its subsidiaries are in compliance with the terms of the Company

Governmental Entity indicated an intention to conduct the same. No
representation or warranty is made in this Section 3.10 with respect to
Environmental Laws (as defined in Section 3.12(a)) and the FCC Licenses (as
defined in Section 3.18).

            3.11.  Employee Plans.

            (a) Section 3.11(a) of the Company Disclosure Schedule lists all
"employee benefit plans," as defined in Section 3(3) of the Employee Retirement

are intended to be "qualified" within the meaning of Sections 401(a) and 501(a)
of the Code, respectively, have been determined by the Internal Revenue Service
to be so "qualified" under such Sections, as amended by the Tax Reform Act of
1986, and the Company knows of no fact which would adversely affect the
qualified status of any such Company Employee Benefit Plan and its related
trust.

            (e) Neither the execution and delivery of this Agreement nor the
consummation of the transactions contemplated hereby will (i) increase any
benefits otherwise payable under any Company Employee Benefit Plan, or (ii)
result in the acceleration of the time of payment or vesting of any such
benefits. Except as contemplated by Section 5.1(f) or 5.16 of this Agreement,

the Company or any of its subsidiaries.

Section 3.25 of the Company Disclosure Schedule, none of the Company's material
programming agreements are subject to renewal prior to December 31, 2000, nor
will any negotiation period relating to the renewal or extension of any material
programming agreement commence prior to December 31, 2000. Except as set forth
on Section 3.25 to the Company Disclosure Schedule, there are no affirmative
obligations under any programming (or similar) agreement to carry any additional
programming channels (or feeds thereof) above and beyond what the Company
currently carries.

            3.26. Consolidation Matters. The Agreement, dated March 5, 1993, as
amended, between ADS Alliance Data Systems, Inc. ("ADS") and the Company is
terminable effective as of June 17, 1999, without the payment of any termination
fee and without the obligation to continue to use or pay for ADS services
following such date. The Company has the contractual right to terminate (i)
Direct Broadcast Satellite Contract No. 104274-B, effective December 31, 1996,
between Lockheed Martin Corporation and the Company, as amended and (ii) the
Billing and Customer Service Agreement between the Company and Convergys
Information Management Group Inc., effective October 16, 1998 and the letter
agreement dated October 16, 1998. The rights of Vulcan Ventures, Inc. and Dow
Jones & Company under their respective programming agreements with the Company
have been suspended effective on the date hereof. Such agreements automatically
terminate upon the Closing of the Merger, and there will be no continuing
payment or performance obligation of the Company under such agreements
thereafter. The Agreement, dated March 21, 1997 between the Company and ADS for
remittance processing service (the "ADS

                                     28
<PAGE>
Remittance Agreement") is terminable effective March 20, 2000 upon prior notice
as required by such agreement. The fees due under the ADS Remittance Agreement
are subject to adjustment in March 1999 as provided in Section 4.2 of such
Agreement. The ADS Remittance Agreement contains minimum fee obligations as
provided in Appendix A thereto.

            3.27. No Other Representations or Warranties. Notwithstanding
anything contained in this Article 3 or any other provision of this Agreement,
it is the explicit intent of each party hereto that the Company is making no
representation or warranty whatsoever, express or implied, except those
representations and warranties of the Company set forth in this Article 3.

                                  ARTICLE 4

                        REPRESENTATIONS AND WARRANTIES
                               OF GM AND HUGHES

            GM and Hughes hereby jointly and severally represent and warrant to
the Company as follows:

            4.1. Organization and Qualification. GM is a corporation duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation or organization and has all requisite
corporate power and authority to own, lease and operate its properties and to
carry on its businesses as now being conducted, except where the failure to be
so organized, existing and in good standing or to have such power and authority
would neither have a Material Adverse Effect on Hughes nor materially impair or
delay the ability of GM to consummate the transactions contemplated hereby. GM
is duly qualified or licensed and in good standing to do business in each
jurisdiction in which the property owned, leased or operated by it or the nature
of the business conducted by it makes such qualification or licensing necessary,
except in such jurisdictions where the failure to be so duly qualified or
licensed and in good standing would neither have a Material Adverse Effect on
Hughes nor may materially impair or delay the ability of GM to consummate the
transactions contemplated hereby.

            4.2. Capitalization of GM and Its Subsidiaries. The Acquiror Stock
is the only class of authorized capital stock of GM as to which GM reports
earnings per share based upon the Available Separate Consolidated Net Income of
Hughes attributable to holders of Acquiror Stock, as provided for under GM's
Amended and Restated Certificate of Incorporation and as set forth in GM's
Annual Report on Form 10-K for the fiscal year ended December 31, 1997. As of
November 30, 1998, 600,000,000 shares of Acquiror Stock were authorized and
105,993,793 shares of Acquiror Stock were issued and outstanding. All of the
issued and outstanding shares of Acquiror Stock have been validly issued, and
are fully paid, nonassessable and free of preemptive rights. As of November 30,
1998, 16,396,454 shares of Acquiror Stock were reserved for issuance and
issuable upon or otherwise deliverable in connection with the exercise of
outstanding options to purchase Acquiror Stock granted by GM or Hughes pursuant
to the GM Amended Stock Incentive Plan and the Hughes Incentive Plan. Except (i)
as described in the GM SEC Reports, and (ii) as set forth above, as of the date
hereof, there are outstanding (A) no securities of GM or


                                     29
<PAGE>
its subsidiaries convertible into or exchangeable for shares of Acquiror Stock,
(B) no options or other rights to acquire from GM or its subsidiaries, and no
obligations of GM or its subsidiaries to issue, any Acquiror Stock, or
securities convertible into or exchangeable for Acquiror Stock, and (C) no
equity equivalents, interests in the ownership or earnings of Hughes or its
subsidiaries or other similar rights (including stock appreciation rights)
(collectively, "Hughes Securities"). There are no outstanding obligations of GM
or any of its subsidiaries to repurchase, redeem or otherwise acquire any
Acquiror Stock.

            4.3. Authority Relative to This Agreement. Each of GM and Hughes has
all necessary corporate power and authority to execute and deliver this
Agreement and to consummate the transactions contemplated hereby. The execution
and delivery of this Agreement and the consummation of the transactions
contemplated hereby have been duly and validly authorized by the Boards of
Directors of GM and Hughes and by GM as the sole shareholder of Hughes, and no
other corporate proceedings on the part of GM or Hughes are necessary to
authorize this Agreement or to consummate the transactions contemplated hereby.
This Agreement has been duly and validly executed and delivered by each of GM
and Hughes and constitutes a valid, legal and binding agreement of each of GM
and Hughes, enforceable against each of GM and Hughes in accordance with its
terms.

            4.4. SEC Reports; Financial Statements. (a) GM has filed all
required forms, reports and documents with the SEC since January 1, 1996 (the
"GM SEC Reports"), each of which has complied in all material respects with all
applicable requirements of the Securities Act and the Exchange Act, each as in
effect on the dates such forms, reports and documents were filed. None of the GM
SEC Reports, including, without limitation, any financial statements or
schedules included or incorporated by reference therein, contained, when filed,
any untrue statement of a material fact or omitted to state a material fact
required to be stated or incorporated by reference therein or necessary in order
to make the statements therein, in light of the circumstances under which they
were made, not misleading. The consolidated financial statements of GM included
in the GM SEC Reports complied as to form in all material respects with
applicable accounting requirements and the published rules and regulations of
the SEC with respect thereto and fairly present, in conformity with GAAP applied
on a consistent basis (except as may be indicated in the notes thereto), the
consolidated financial position of GM and its consolidated subsidiaries as of
the dates thereof and their consolidated results of operations and changes in
financial position for the periods then ended (subject, in the case of the
unaudited interim financial statements, to (A) normal year-end adjustments and
(B) any other adjustments described in the GM SEC Reports filed prior to the
date of this Agreement (the "Filed GM SEC Reports")).

            (b) Hughes has heretofore made available to the Company a complete
and correct copy of any material amendments or modifications, which have not yet
been filed with the SEC, to agreements, documents or other instruments which
previously had been filed by GM with the SEC pursuant to the Exchange Act, to
the extent that Hughes or DIRECTV is a party to such agreements or such
agreements relate to the business of Hughes or DIRECTV.

            4.5.  Information Supplied.

            (a) None of the information supplied or to be supplied by GM or
Hughes for inclusion in the Proxy Statement will, at the date mailed to
shareholders of the Company and at the time of the meeting of shareholders of
the Company to be held in connection with the Merger, 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 are made, not misleading. If at any time
prior to the Effective Time, any event with respect to GM, its officers and
directors or any of its subsidiaries should occur which is required to be
described in the Proxy Statement, GM shall promptly so advise the Company.

            (b) Neither the S-4 nor any amendment thereto will at the time it
becomes effective under the Securities Act or at the Effective Time 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 are made, not misleading. No
representation or warranty is made by GM or Hughes in this Section 4.5 with
respect to statements made or incorporated by reference therein based on
information supplied by the Company or any of its subsidiaries for inclusion or
incorporation by reference in the S-4. The S-4 will comply as to form in all
material respects with the provisions of the Securities Act and the rules and
regulations thereunder.

            4.6. Consents and Approvals; No Violations. Except for filings,
permits, authorizations, consents and approvals as may be required under, and
other applicable requirements of, the Securities Act, the Exchange Act, state
securities or blue sky laws, the HSR Act, the Communications Act, the filing and
recordation of a certificate of merger as required by the DGCL, and the filing
of articles of merger as required by the MBCA, no filing with or notice to, and
no permit, authorization, consent or approval of, any Governmental Entity is
necessary for the execution and delivery by GM or Hughes of this Agreement or
the consummation by GM or Hughes of the transactions contemplated hereby, except
where the failure to obtain such permits, authorizations, consents or approvals
or to make such filings or give such notice would neither have a Material
Adverse Effect on Hughes nor materially impair or delay the ability of GM to
consummate the transactions contemplated hereby. Except as set forth in Section
4.6 of the GM Disclosure Schedule, neither the execution, delivery and
performance of this Agreement by GM or Hughes nor the consummation by GM or
Hughes of the transactions contemplated hereby will (i) conflict with or result
in any breach of any provision of the respective certificate or articles of
incorporation or bylaws (or similar governing documents) of GM or Hughes or any
of GM's subsidiaries, (ii) result in a violation or breach of, or constitute
(with or without due notice or lapse of time or both) a default (or give rise to
any right of termination, amendment, cancellation or acceleration or Lien)
under, any of the terms, conditions or provisions of any note, bond, mortgage,
indenture, lease, license, contract, agreement or other instrument or obligation
to which GM or Hughes or any of GM's subsidiaries is a party or by which any of
them or any of their respective properties or assets may be bound or (iii)
violate any order, writ, injunction, decree, law, statute, rule or regulation
applicable to GM or Hughes or any of GM's subsidiaries or any of their
respective properties or assets, except in the case of (ii) or (iii) for
violations, breaches or defaults which would neither have a Material Adverse

                                     31
<PAGE>
Effect on Hughes nor materially impair or delay the ability of GM to consummate
the transactions contemplated hereby.

            4.7. No Default. None of GM or its subsidiaries is in default or
violation (and no event has occurred which with or without due notice or the
lapse of time or both would constitute a default or violation) of any term,
condition or provision of (i) its certificate or articles of incorporation or
bylaws (or similar governing documents), (ii) any note, bond, mortgage,
indenture, lease, license, contract, agreement or other instrument or obligation
to which GM or any of its subsidiaries is now a party or by which any of them or
any of their respective properties or assets may be bound or (iii) any order,
writ, injunction, decree, law, statute, rule or regulation applicable to GM, its
subsidiaries or any of their respective properties or assets, except in the case
of (ii) or (iii) for violations, breaches or defaults which would neither have a
Material Adverse Effect on Hughes nor materially impair or delay the ability of
GM to consummate the transactions contemplated hereby.

            4.8. No Undisclosed Liabilities; Absence of Changes. Except as and
to the extent disclosed by GM in the GM SEC Reports filed prior to the date of
this Agreement (the "Filed GM SEC Reports"), since January 1, 1998, (a) neither
GM nor its subsidiaries has incurred any liabilities or obligations of any
nature, whether or not accrued, contingent or otherwise, and whether due or to
become due or asserted or unasserted, which would either have a Material Adverse
Effect on Hughes or materially impair or delay the ability of GM to consummate
the transactions contemplated hereby, (b) except as contemplated by this
Agreement, Hughes and its subsidiaries have conducted their respective
businesses in all material respects in the ordinary course consistent with past
practices, (c) GM has not paid any dividend or distribution in respect of, or
redeemed or repurchased any of, the Acquiror Stock or other securities directly
or indirectly convertible into or exercisable or exchangeable for any Acquiror
Stock, and (d) except as required by GAAP, neither GM nor Hughes has changed its
method of accounting (either for financial accounting or tax purposes) in any
manner which would reasonably be expected to materially adversely affect the
valuation of the Acquiror Stock.

            4.9. Litigation. Except as disclosed by GM in the Filed GM SEC
Reports, there is no suit, claim, action, proceeding or investigation pending
or, to the knowledge of GM, threatened against GM or any of its subsidiaries or
any of their respective properties or assets which, individually or in the
aggregate, would either have a Material Adverse Effect on Hughes or materially
impair or delay the ability of GM to consummate the transactions contemplated
hereby. Except as disclosed by GM in the Filed GM SEC Reports, none of GM or its
subsidiaries is subject to any outstanding order, writ, injunction or decree
which would either have a Material Adverse Effect on Hughes or materially impair
or delay the ability of GM to consummate the transactions contemplated hereby.

            4.10. Compliance with Applicable Law. Except as disclosed by GM in
the Filed GM SEC Reports, GM and its subsidiaries hold all permits, licenses,
variances, exemptions, orders and approvals of all Governmental Entities
necessary for the lawful conduct of their respective businesses (the "GM
Permits"), except for failures to hold such permits, licenses, variances,
exemptions, orders and approvals which would neither have a Material Adverse
Effect on Hughes nor materially impair or delay the ability of GM to

                                     32
<PAGE>
consummate the transactions contemplated hereby. Except as disclosed by GM in
the Filed GM SEC Reports, GM and its subsidiaries are in compliance with the
terms of the GM Permits, except where the failure so to comply would neither
have a Material Adverse Effect on Hughes nor materially impair or delay the
ability of GM to consummate the transactions contemplated hereby. Except as

subsidiaries are not being conducted in violation of any law, ordinance or
regulation of any Governmental Entity except for violations or possible

impair or materially delay the ability of GM to consummate the transactions
contemplated hereby. Except as publicly disclosed by GM in the Filed GM SEC
Reports, no investigation or review by any Governmental Entity with respect to
GM or its subsidiaries is pending or, to the knowledge of GM, threatened, nor,
to the knowledge of GM, has any Governmental Entity indicated an intention to
conduct the same, other than, in each case, those the outcome of which would
neither have a Material Adverse Effect on Hughes nor materially impair or delay
the ability of GM to consummate the transactions contemplated hereby. No
representation or warranty is made in this Section 4.10 with respect to
Environmental Laws and the FCC Licenses.

            4.11. Brokers. No broker, finder or investment banker (other than

            4.12.  Employee Plans.

            (a) Section 4.12(a) of the Disclosure Schedule previously delivered

"employee benefit plans," as defined in Section 3(3) of ERISA and all bonus and
other incentive compensation, disability, severance, retention, salary
continuation, stock and other stock-related award, stock option, stock purchase,
collective bargaining or workers' compensation agreements, plans, policies and
arrangements generally made available to the employees of DIRECTV and which will
be made available to the employees of the Company (each, a "DIRECTV Benefit
Plan" and collectively, the "DIRECTV Benefit Plans").

            (b) Except as set forth in the Filed GM SEC Reports or would not,

collective bargaining agreement have been timely made; (ii) Hughes has performed
all obligations required to be performed by it under any DIRECTV Employee
Benefit Plan; (iii) the DIRECTV Employee Benefit Plans comply in all respects
and have been maintained in compliance with their terms and the requirements of
ERISA, the Code and other applicable laws; and (iv) there are no actions, suits,
arbitrations or claims (other than routine claims for benefits) pending or, to
the knowledge of Hughes, threatened with respect to any DIRECTV Employee Benefit
Plan.

            (c) Each DIRECTV Employee Benefit Plan and its related trust which
are intended to be "qualified" within the meaning of Sections 401(a) and 501(a)
of the Code,

                                     33
<PAGE>
respectively, have been determined by the Internal Revenue Service to be so
"qualified" under such Sections, as amended by the Tax Reform Act of 1986, and
Hughes knows of no fact which would adversely affect the qualified status of any
such DIRECTV Employee Benefit Plan and its related trust.

            4.13. Environmental Matters. Except as would not reasonably be
expected to have a Material Adverse Effect on Hughes, (1) Hughes is in
compliance with Environmental Laws; (2) no judicial or administrative
proceedings are pending or, to the knowledge of Hughes, threatened against
Hughes or any real property owned or operated by Hughes alleging the violation
of or seeking to impose liability under any Environmental Law, and there are no
investigations of an environmental nature pending or, to the knowledge of
Hughes, threatened against Hughes or any real property owned or operated by
Hughes; and (3) there are no facts, circumstances or conditions relating to,
arising from or attributable to Hughes or any real property currently or, to the
knowledge of Hughes, formerly owned, operated or leased by Hughes that are
reasonably likely to result in Hughes incurring liabilities under Environmental

the FCC held by DIRECTV (the "DIRECTV FCC Licenses"). Except as is not material
to the conduct of the business of DIRECTV: (i) DIRECTV is financially qualified
and, to the knowledge of Hughes, is otherwise qualified to hold the DIRECTV FCC
Licenses or to control the DIRECTV FCC Licenses, as the case may be; (ii) the
DIRECTV FCC Licenses constitute all permits, licenses, waivers or authorizations
that DIRECTV is required by the FCC to hold in connection with the operation of
its business as currently conducted; (iii) DIRECTV is not aware of any facts or
circumstances relating to the FCC qualifications of Hughes that would prevent
the FCC's granting the FCC Application; (iv) DIRECTV is in compliance with all
DIRECTV FCC Licenses and with the Communications Act; and (v) there is not
pending or, to the knowledge of Hughes threatened, any application, petition,
objection or other pleading with the FCC or other governmental authority which
challenges the validity of, or any rights of the holder under, any DIRECTV FCC
License.

            4.15. No Other Representations or Warranties. Notwithstanding
anything contained in this Article 4 or any other provision of this Agreement,
it is the explicit intent of each party hereto that neither GM nor Hughes is
making any representation or warranty whatsoever, express or implied, except
those representations and warranties of GM and Hughes set forth in this Article
4.

subsidiary of Hughes into Hughes or another subsidiary of Hughes or (ii) an
acquisition or disposition of a business or assets, except for any such
acquisition or disposition which would have a Material Adverse Effect on
Hughes);

                                     37
<PAGE>
            (c) alter through merger, liquidation, reorganization, restructuring
or in any other fashion the corporate structure or ownership of Hughes or any of
its subsidiaries, except for any such alteration which would not have a Material
Adverse Effect on Hughes; or

            (d) take any action, or agree to take any action, which would have
the effect of terminating Hughes's engaging in the multichannel entertainment
distribution industry.

            5.3.  Preparation of S-4 and the Proxy Statement.

            (a) The Company will, as promptly as practicable, prepare and file
with the SEC the Proxy Statement in connection with the vote of the shareholders
of the Company with respect to the Merger. GM and Hughes shall have a reasonable
opportunity to review the Proxy Statement and any supplement thereto prior to
the filing or submission thereof to the SEC.

            (b) GM will, as promptly as practicable, prepare, following receipt
of notification from the SEC that it has no further comments on the Proxy
Statement, and file with the SEC the S-4 in connection with the registration
under the Securities Act of the shares of Acquiror Stock issuable upon
conversion of the Shares and the other transactions contemplated hereby. The
Company will have a reasonable opportunity to review the S-4 and any amendments
thereto prior to the filing thereof with the SEC.

            (c) GM and the Company will, and will cause their accountants and
lawyers to, use all reasonable best efforts to have or cause the S-4 declared
effective as promptly as practicable after it is filed, and will take any other
action required or necessary to be taken under federal or state securities laws
or otherwise in connection with the registration process. The Company will use
its reasonable best efforts to cause the Proxy Statement to be mailed to its
shareholders at the earliest practicable date after the S-4 shall become
effective.

            5.4. Company Meeting. The Company shall call a meeting of its
shareholders to be held as promptly as practicable for the purpose of voting
upon this Agreement and the Merger. The Company agrees that its obligations
pursuant to the first sentence of this Section 5.4 shall not be affected by the
commencement, public proposal, public disclosure or communication to the Company
of any Acquisition Proposal (as defined in Section 5.5). The Company shall use
its reasonable best efforts to hold such meeting as soon as practicable after
the date hereof and will, through the Company Board, subject to the fiduciary
duties of the Company Board, recommend to its shareholders approval of this
Agreement and the Merger.

            5.5. No Solicitation.

            (a) Until the termination of this Agreement, the Company shall not,
and shall not permit any of its subsidiaries, or any of its or its subsidiaries'
officers, directors, employees, representatives, agents or affiliates
(including, without limitation, any investment

                                     38
<PAGE>
banker, financial advisor, attorney, accountant or other representative of the
Company or any of its subsidiaries), to, directly or indirectly, initiate,
solicit or knowingly encourage (including by way of furnishing non-public
information or assistance), or take any other action to facilitate, any
inquiries or the making of any proposal that constitutes, or may reasonably be
expected to lead to, an Acquisition Proposal (as defined below), or enter into
or maintain or continue discussions or negotiate with any person or entity in
furtherance of such inquiries or to obtain an Acquisition Proposal or agree to
or endorse any Acquisition Proposal, or authorize or permit any of its officers,
directors or employees or any of its subsidiaries or any investment banker,
financial advisor, attorney, accountant or other representative of it or any of
its subsidiaries to take any such action; provided, however, that the Company
may engage in discussions with any person or entity for the sole purpose of
clarifying the terms of any unsolicited Acquisition Proposal if such discussions
are in the judgment of independent counsel to the independent directors of the
Company (as set forth in a reasoned legal opinion delivered to Hughes prior to
any such discussions), required by the fiduciary duties of the Company Board.
The Company will promptly (and in no event later than twenty-four (24) hours
after receipt of any Acquisition Proposal) notify (which notice shall be
provided orally and in writing and shall identify the person making such
Acquisition Proposal and set forth the material terms thereof) Hughes after any
receipt of any Acquisition Proposal. For purposes of this Agreement,
"Acquisition Proposal" means any proposal regarding any of the following (other
than the transactions contemplated by this Agreement) involving the Company or
any of its subsidiaries: (w) any merger, consolidation, share exchange,
recapitalization, business combination or other similar transaction; (x) any
sale, lease, exchange, mortgage, pledge, transfer or other disposition of
fifteen percent (15%) or more of the assets of the Company and its subsidiaries,
taken as a whole, in a single transaction or series of related transactions; (y)
any tender offer or exchange offer that if consummated would result in any
person (other than HBI) beneficially owning more than fifteen percent (15%) of
the outstanding shares of Company Common Stock or the filing of a registration
statement under the Securities Act in connection therewith; or (z) any public
announcement of a proposal, plan or intention to do any of the foregoing or any
agreement to engage in any of the foregoing.

            (b) Until the termination of this Agreement, the Company Board shall
not (i) subject to the fiduciary duties of the Company Board, withdraw or
modify, or propose to withdraw or modify, in a manner adverse to GM or Hughes,
the approval or recommendation of the Merger, this Agreement and the
Shareholders Agreement by the Company Board, (ii) approve or recommend, or
propose to approve or recommend, any Acquisition Proposal or (iii) cause the
Company or any of its subsidiaries to enter into any agreement (including,
without limitation, any letter of intent) with respect to any Acquisition
Proposal.

            5.6. Letter of the Company's Accountants. The Company shall use all
reasonable best efforts to cause to be delivered to GM a letter of Arthur
Andersen LLP (or its successor firm), the Company's independent auditors, dated
a date within two (2) business days before the date on which the S-4 shall
become effective and addressed to GM, in form and substance reasonably
satisfactory to GM and customary in scope and substance for letters delivered by
independent public accountants in connection with registration statements
similar to the S-4.

                                     39

            5.7.  Access to Information.

            (a) Between the date hereof and the Effective Time, the Company will
give GM and Hughes and their authorized representatives reasonable access to all
employees (which access shall be coordinated with the Company's executive
management), plants, offices, warehouses and other facilities and to all books
and records of the Company and its subsidiaries, will permit GM and Hughes to
make such inspections as GM and Hughes may reasonably require and will cause the
Company's officers and those of its subsidiaries to furnish GM and Hughes with
such financial and operating data and other information with respect to the
business, properties and personnel of the Company and its subsidiaries as GM or
Hughes may from time to time reasonably request; provided, that no investigation
pursuant to this Section 5.7(a) shall affect or be deemed to modify any of the
representations or warranties made by the Company and provided, further, except
as provided in Section 6.3(i), that information heretofore redacted by the
Company and relating to exclusivity and renegotiation provisions of programming
agreements may, at the Company's discretion, be provided only in redacted form
(contracts containing such redaction being referred to herein as the "Redacted
Contracts").

            (b) From and after the date of this Agreement, Hughes shall have the
right, but not the obligation, to retain one or more environmental professionals
to conduct an environmental assessment and investigation ("Environmental
Investigation") of the Properties, which Environmental Investigation shall be
conducted as promptly as reasonably practicable in consultation with the Company
and shall include the right to conduct such tests of soil, groundwater, surface
water or air that Hughes reasonably requires, in its sole discretion, to
determine whether there exists an Adverse Environmental Condition at any of the
Properties. For purposes of this Agreement, "Adverse Environmental Condition"
shall mean any of the following: (i) the existence, or the continuation of the
existence, of a Release (including, without limitation, sudden or non-sudden,
accidental or non-accidental Releases), of, or exposure to, any Hazardous
Substance at, in, by, from or related to the Properties, (ii) damage or injury
to the environment in connection with the transportation, storage, treatment or
disposal (or the arrangement thereof) of Hazardous Substances in connection with
the operation of the Company or its subsidiaries or (iii) the violation, or
alleged violation, of Environmental Law by the Company or any of its
subsidiaries.

            (c) Between the date hereof and the Effective Time, the Company
shall furnish to Hughes (i) within two business days after the delivery thereof
to management, such monthly financial statements and data as are regularly
prepared for distribution to the Company's Chief Executive Officer and (ii) at
the earliest time at which they are available and prior to filing thereof with
the SEC, such quarterly and annual financial statements as are prepared for the
Company's SEC filings, which shall be in accordance with the books and records
of the Company, and drafts of all such Company SEC filings.

            (d) Each of GM and Hughes will hold and will cause its consultants
and advisors to hold in confidence all documents and information concerning the
Company and its subsidiaries furnished to GM or Hughes in connection with the
transactions contemplated by this Agreement to the extent required by that
certain confidentiality agreement entered


                                     40
<PAGE>
into between the Company, DIRECTV and Hughes dated December 1, 1998 (the
"Confidentiality Agreement").

            5.8. Additional Agreements; Reasonable Best Efforts. Subject to the
terms and conditions herein provided, each of the parties hereto agrees to use
its reasonable best efforts to take, or cause to be taken, all action, and to
do, or cause to be done, all things reasonably necessary, proper or advisable
under applicable laws and regulations to consummate and make effective the
transactions contemplated by this Agreement, including, without limitation, (i)
cooperation in the preparation and filing of the Proxy Statement and the S-4,
any filings that may be required under the HSR Act and the Communications Act,
and any amendments to any thereof, (ii) cooperation in obtaining, prior to the
Effective Time, the approval for listing on the NYSE, effective upon the
official notice of issuance, of the shares of Acquiror Stock into which the
Shares will be converted pursuant to Article 2 hereof, (iii) the taking of all
action reasonably necessary, proper or advisable to secure any necessary
consents of all third parties and Governmental Entities, including those
relating to existing debt obligations of the Company and its subsidiaries, (iv)
the transfer of existing Environmental Permits to Hughes (or, if such transfer
is not permissible, the Company shall assist Hughes in obtaining new
Environmental Permits as necessary), (v) contesting any legal proceeding
relating to the Merger and (vi) the execution of any additional instruments
necessary to consummate the transactions contemplated hereby. Subject to the
terms and conditions of this Agreement, GM, Hughes and the Company agree to use
all reasonable efforts to cause the Effective Time to occur as soon as
practicable after the shareholder vote with respect to the Merger. In case at
any time after the Effective Time any further action is necessary to carry out
the purposes of this Agreement, the proper officers and directors of each party
hereto shall take all such necessary action.

            5.9. Regulatory Reviews. Each party hereto will use its reasonable
best efforts (a) to file with the U.S. Department of Justice and U.S. Federal
Trade Commission, as soon as practicable after the date hereof, the Notification
and Report Form under the HSR Act and any supplemental information or material
requested pursuant to the HSR Act, and (b) to comply as soon as practicable
after the date hereof with any other laws of any country and the European Union
under which any consent, authorization, registration, declaration or other
action with respect to the transactions contemplated herein may be required.
Each party hereto shall furnish to the other such information and assistance as
the other may reasonably request in connection with any filing or other act
undertaken in compliance with the HSR Act or other such laws, and shall keep
each other timely apprised of the status of any communications with, and any
inquiries or requests for additional information from, any Governmental Entity
under the HSR Act or other such laws. Hughes and the Company will each use its
reasonable best efforts to cause termination of the HSR waiting period(s) in
connection with any review of the transactions contemplated by this Agreement
under the HSR Act. In connection with any litigation or administrative
proceeding instituted to prevent the consummation of the Merger, Hughes and the
Company shall take any and all action reasonably necessary in connection with
such litigation or administrative proceeding (i) to prevent the entry of any
order, preliminary or permanent injunction, or other legal restraint or
prohibition preventing consummation of the Merger or any related transactions
contemplated by this Agreement and (ii) to vacate any order, injunction of legal
restraint or prohibition which would prevent the consummation of the
transactions contemplated by this


                                     41
<PAGE>
Agreement; provided, however, that nothing contained herein shall require Hughes
to divest any portion of Hughes or the Company or to accept any restrictions or
the operation of Hughes or the Company in order to consummate the transactions
contemplated this Agreement.

            5.10. Public Announcements. Each of GM, Hughes and the Company will
agree on the text of any press release before issuing any press release or
otherwise making any public statements with respect to the transactions
contemplated by this Agreement, including, without limitation, the Merger. The
press release or public statement shall make appropriate reference to the role
of the Company and the HBI family in the development of the direct-to-home
satellite broadcasting business. None of GM, Hughes or the Company shall issue
any such press release or make any such public statement prior to such
agreement, except as may be required by applicable law or by obligations
pursuant to any agreement with the NYSE or NASDAQ, as determined by GM, Hughes
or the Company, as the case may be, in which case such release or statement
shall be limited to a factual summary of the material provisions of this
Agreement and the transactions contemplated hereby.

            5.11.  Directors' and Officers' Insurance; Indemnification.

            (a) Directors' and Officers' Insurance. Hughes will provide, for an
aggregate period of not less than six (6) years from the Effective Time, the
directors and officers of the Company who are currently covered by the Company's
existing insurance and indemnification policy an insurance and indemnification
policy that provides coverage for events occurring prior to the Effective Time
(the "D&O Insurance") that is no less favorable than the Company's existing
policy or, if substantially equivalent insurance coverage is unavailable, the
best available coverage; provided that Hughes shall not be required to pay an
annual premium for the D&O Insurance in excess of 150% of the last annual
premium paid prior to the date hereof, but in such case shall purchase as much
coverage as possible for such amount.

            (b) Indemnification. To the extent, if any, not provided by a right
under one of the parties' directors and officers liability insurance policies,
from and after the Effective Time, Hughes shall, to the fullest extent permitted
by applicable law and consistent with the by-laws of Hughes, indemnify, defend
and hold harmless each person who is now, or has been at any time prior to the
date hereof, or who becomes prior to the Effective Time, a director or officer
of the Company (each an "Indemnified Party" and, collectively, the "Indemnified
Parties") against all losses, expenses (including reasonable attorneys' fees and
expenses), claims, damages or liabilities or, subject to the proviso of the next
succeeding sentence, amounts paid in settlement, arising out of actions or
omissions occurring at or prior to the Effective Time and whether asserted or
claimed prior to, at or after the Effective Time that are in whole or in part
(i) based on, or arising out of the fact that such person is or was a director
or officer of the Company or (ii) based on, arising out of or pertaining to the
transactions contemplated by this Agreement. In the event of any such loss,
expense, claim, damage or liability (whether or not arising before the Effective
Time), in addition to any indemnification and hold harmless hereunder (i) Hughes
shall pay the reasonable fees and expenses of counsel selected by the
Indemnified Parties, which counsel shall be reasonably satisfactory to Hughes,
promptly after statements therefor are received and otherwise advance


                                     42
<PAGE>
to such Indemnified Party upon request reimbursement of documented expenses
reasonably incurred, in either case to the extent not prohibited by the DGCL and
upon receipt of any affirmation and undertaking required by the DGCL and (ii)
Hughes will cooperate in the defense of any such matter; provided, however, that
Hughes shall not be liable for any settlement effected without its written
consent. The Indemnified Parties as a group may retain only one law firm with
respect to each related matter.

            (c) Successors. In the event Hughes or any of its successors or
assigns (i) consolidates with or merges into any other person and shall not be
the continuing or surviving corporation or entity or such consolidation or
merger or (ii) transfers all or substantially all of its properties and assets
to any person, then and in either such case, proper provision shall be made so
that the successors and assigns of Hughes shall assume the obligations set forth
in this Section 5.11.

            (d) Benefit. The provisions of this Section 5.11 are intended to be
for the benefit of, and shall be enforceable by, each Indemnified Party, his or
her heirs and his or her representatives.

            5.12. Notification of Certain Matters. The Company, on the one hand,
and GM and Hughes, on the other, shall give prompt notice to each other of (i)
the occurrence or nonoccurrence of any event the occurrence or nonoccurrence of
which would be likely to cause any representation or warranty contained in this
Agreement to be untrue or inaccurate in any material respect at or prior to the
Effective Time, (ii) any material failure of a party to comply with or satisfy
any covenant, condition or agreement to be complied with or satisfied by it
hereunder, (iii) any notice of, or other communication relating to, a default or
event which, with notice or lapse of time or both, would become a default,
received by a party or any of its subsidiaries subsequent to the date of this
Agreement and prior to the Effective Time, under any contract or agreement
material to the financial condition, properties, businesses or results of
operations of a party and its subsidiaries taken as a whole to which it or any
of its subsidiaries is a party or is subject, (iv) any notice or other
communication from any third party alleging that the consent of such third party
is or may be required in connection with the transactions contemplated by this
Agreement, or (v) any Material Adverse Effect on a party; provided, that the
delivery of any notice pursuant to this Section 5.12 shall not cure such breach
or non-compliance or limit or otherwise affect the remedies available hereunder
to GM and Hughes.

            5.13. Tax-Free Reorganization Treatment. The Company, the
significant shareholders of the Company, and Hughes (on behalf of GM and Hughes)
shall execute and deliver to Leonard, Street and Deinard Professional
Association, counsel to the Company, and Weil, Gotshal & Manges LLP, counsel to
Hughes and GM, certificates containing customary representations relating to
their business operations and substantially in the forms attached hereto as
Exhibits B-1, B-2 and B-3 (with such changes as may be reasonably requested by
such law firms) at such time or times as may be reasonably requested by such law
firms in connection with their respective deliveries of opinions, pursuant to
Sections 6.2(e) and 6.3(h) hereof, with respect to the tax-free reorganization
treatment of the Merger. Prior to the Effective Time, none of the Company, GM or
Hughes shall take or cause to be taken any action which would cause to be untrue
(or fail to take or cause not to


                                     43
<PAGE>
be taken any action which would cause to be untrue) any of the representations
in such certificates.

            5.14. Company Affiliates. Prior to the Closing Date, the Company
shall deliver to GM a letter identifying each affiliate (as such term is defined
in Rule 12b-2 under the Exchange Act) of the Company at the time the Merger is
submitted for approval to the shareholders of the Company (each a "Company
Affiliate") and the Company shall use its reasonable best efforts to cause each
Company Affiliate to deliver to GM on or prior to the Closing Date, a written
agreement that such Company Affiliate will not sell, pledge, transfer or
otherwise dispose of any shares of Acquiror Stock issued to such Company
Affiliate pursuant to the Merger, except in compliance with Rule 145 promulgated
under the Securities Act or an exemption from the registration requirements of
the Securities Act.

            5.15. SEC Filings. Each of GM and the Company shall promptly provide
the other party (or its counsel) with copies of all filings made by the other
party or any of its subsidiaries with the SEC or any other state or federal
Governmental Entity in connection with this Agreement and the transactions
contemplated hereby.

            5.16.  Employee Matters.

            (a) All employees of the Company who are actively at work as of the
Closing Date shall be employed immediately after the Closing Date at a rate of
salary comparable to the salary rate in effect for such employee as of the date
immediately preceding the Closing Date. All employees of the Company who are on
unpaid leave as of the Closing Date and who have rights of re-employment upon
termination of such individual's leave shall be employed by DIRECTV upon such
termination and shall not receive any salary until the return of such employees
to active work with DIRECTV. Section 5.16(a) of the Company Disclosure Schedule
sets forth a list of all employees of the Company, their positions, status and
rates of salary as of November 24, 1998.

            (b) If any employee of the Company is required within the first
twelve (12) months after the Closing Date by DIRECTV to relocate to a facility
that was owned by DIRECTV immediately prior to the Closing Date and such
employee accepts such relocation, such employee shall be provided with (i) the
standard relocation benefits under the DIRECTV Relocation Allowances Policy (the
"Relocation Package") and (ii) an adjusted salary rate for comparable positions
at DIRECTV at such DIRECTV facility; provided, that any such employee who is
required to relocate pursuant to this paragraph shall be provided with up to two
(2) weeks to consider such relocation.

            (c) Any employee of the Company who (i) (x) is actively at work as
of the Closing Date or (y) is on an authorized leave of absence as of the
Closing Date, has rights of re-employment upon termination of such individual's
leave, and is able to return to work, and (ii) (x) has not accepted a Relocation
Package and within twelve (12) months after the Closing terminates employment
with DIRECTV (other than any employee whose employment was terminated or could
have been terminated for cause, death or disability) or (y) has accepted a
Relocation Package and within twelve (12) months after the Closing is terminated
by DIRECTV without cause, shall be entitled to receive severance pay of six (6)
months'

                                     44
<PAGE>
salary (in lump sum), career counseling and outplacement services (consistent
with the counseling and outplacement services previously provided to similarly
situated employees of DIRECTV); provided, however, that no such severance shall
be paid under this Section 5.16(c) unless (i) such employee has signed a full
release of any claims against DIRECTV, the Company and any of their affiliates
and (ii) such employee, if voluntarily terminating his or her employment with
DIRECTV, has provided at least two (2) weeks' notice to DIRECTV; and provided,
further, that any severance paid under this Section 5.16(c) shall be reduced by
the amount of any payment under the Worker Adjustment and Retraining
Notification Act and by the amount of severance paid or payable under any other
plan or arrangement, but not any severance paid pursuant to Section 5.16(e)
hereof. Any person receiving a severance payment under this Section 5.16(c)
shall not be entitled to any payment or benefit under the Hughes Employment
Transition Assistance Plan.

            (d) Subject to applicable laws and Sections 5.16(a), (b), (c) and
(e) hereof, DIRECTV shall have the right to terminate the employment of any
employee of the Company who becomes an employee of DIRECTV, with or without
cause, change the terms and conditions of employment of any such employee, and
amend or terminate any employee benefit plans or employee arrangements
applicable to such employees.

            (e) The Company and DIRECTV shall establish a program ("Program")
pursuant to which $15 million shall be made available to be awarded to current
employees and certain former employees of the Company and certain current
employees of HBI. The amount of individual awards shall be as heretofore
established by the executive management of the Company with the approval of
DIRECTV. Awards under the Program to any participating employee shall be payable
on (i) the first anniversary of the Closing Date, (ii) with respect to current
employees of the Company, such participating employee's termination of
employment by reason of death or disability or by DIRECTV without cause, if
earlier, or (iii) with respect to current employees of HBI, the termination of
the Transition Services Agreement by DIRECTV, if earlier. No person shall be
entitled to payment of an award if such person is terminated or could have been
terminated for cause or resigns from employment with the Company, DIRECTV and
their affiliates, and awards with respect to such persons shall be forfeited.
The amount payable with respect to any award under the Program shall be reduced
by the amount paid or payable under any change-in-control, retention or similar
arrangements, but not any severance paid pursuant to Section 5.16(c) hereof. For
purposes of this Section 5.16(e), a termination of employment by DIRECTV
"without cause" shall include a termination of employment by a participating
employee resulting from a material reduction in his or her job duties or salary,
which reduction shall have continued for a period of ten (10) days after written
notice to DIRECTV.

            (f) For purposes of this Section 5.16, "cause" shall mean: (A)
fraud, embezzlement, theft or material dishonesty against the Company or the
Surviving Corporation, any of their subsidiaries or the Board of Directors; (B)
conviction of or plea of nolo contendere to any crime (whether or not involving
the Company or the Surviving Corporation) constituting a felony in the
jurisdiction involved; provided, that such felony is related to such employee's
job responsibility or the safety of co-workers; (C) a willful failure by the
employee to follow reasonable directions or instructions of his or her
supervisor and, in the case of senior officers, the Board of Directors, in each
case consistent with his or her

                                     45
<PAGE>
position, which failure shall have continued for a period of time that allows
the progressive discipline policy to be followed and shall not be the result of
the employee's physical or mental incapacity or disability, provided that the
employee's resignation during such time shall not be effective without the
written consent of the Company; or (D) willful misconduct in the performance of
the employee's duties which results in material damage to or material liability
of the Company, the Surviving Corporation or any of their subsidiaries.

            (g) Service by the employees of the Company who are actively at work
as of the Closing Date or who are on authorized leave of absence as of the
Closing Date with rights of re-employment upon termination of such leave and
return to active work shall be recognized under any benefit plan or arrangement
established, maintained or contributed to by DIRECTV or its affiliates after the
Closing Date for the benefit of any such employee solely for purposes of
eligibility and vesting, except that, with respect to DIRECTV's Non-Bargaining
Retirement Plan, such service shall be recognized solely for purposes of
vesting; provided, that such recognition does not result in any duplication of
benefits. Individuals who have terminated employment with the Company prior to
the Closing Date and are subsequently hired by DIRECTV or its affiliates will
not be entitled to any service recognition under this paragraph.

            (h) Hughes shall cause DIRECTV to perform all of the obligations
under this Section 5.16, and all rights hereunder are intended to accrue to the
benefit of DIRECTV.

            (i) Notwithstanding anything to the contrary herein, in the event
that any payment pursuant to this Section 5.16, together with any payment or
benefit received or to be received by any person pursuant to the terms of this
Agreement or of any other plan, arrangement or agreement of the Company or its
affiliates (each a "Payment" and collectively, the "Payments"), would be subject
to the excise tax imposed by Section 4999 of the Code (the "Excise Tax") either
in whole or in part, the Payments shall be reduced (but not below zero) until no
portion of the Payments would be subject to the Excise Tax. The Company and HBI
agree to provide all such information DIRECTV may request to determine whether
and to what extent the Excise Tax applies to any Payment. Each recipient of a
Payment pursuant to this Section 5.16 shall be required to agree, as a condition
to receiving such Payment, to indemnify and hold GM, Hughes and their respective
affiliates harmless with respect to any liability for the Excise Tax arising
from or relating to the Payments if it is established that such Payments
resulted in the imposition of the Excise Tax.

            5.17. Ancillary Agreements. On or prior to the Closing Date, Hughes
shall, or shall cause DIRECTV to, and the Company shall, or shall use its
reasonable best efforts to cause its relevant affiliates to, enter into the
following agreements (the "Ancillary Agreements"): (i) Consulting Agreements,
substantially in the form of Exhibit C hereto, with the Chairman, the President
and the Executive Vice President of the Company, (ii) a Non-Competition
Agreement, substantially in the form of Exhibit D hereto, binding HBI and the
foregoing officers, and (iii) a Transition Services Agreement, substantially in
the form of Exhibit E hereto, providing for certain transition services to be
provided by HBI to the Company. Concurrently with the execution of this
Agreement, Hughes and the Company have entered into (i) a Replacement Payload

event that this Agreement is terminated pursuant to Section 7.1(g) and (ii) a

hereto, providing for channel capacity and related services to be provided to
the Company in the event of a "Total Failure" (as defined therein) of DBS-1.

reasonably satisfactory to the Company, in the event the transactions
contemplated by this Agreement are not consummated, with billing and customer

(the length of such period to be determined by the Company in its sole
discretion) commencing on the later of July 1, 1999 or the date on which this
Agreement is terminated pursuant to Section 7.1 at the rates specified in the

existing contractual right to terminate its contract with Convergys within two
(2) weeks of the date hereof. The parties hereto agree that the payment by the
Company of any fee or penalty pursuant to such contract on account of such
termination shall not be a violation of Section 5.1 hereof and shall not
constitute a Material Adverse Effect. Each of the Company and Hughes covenants
and agrees to use its reasonable best efforts to reduce the amount of such
termination fee or penalty. In the event the Company utilizes the billing and
customer management systems of DIRECTV, DIRECTV shall use its reasonable best
efforts to assist the Company in transitioning such services to DIRECTV and,
subsequently, transitioning such services to a third party service provider.

            5.19. 110(degree) Construction Permit. The Company and Hughes will
cooperate and use their reasonable best efforts to maintain (including, without

Construction Permit which may include, without limitation, the use of a
satellite produced by Hughes. The Company, with prior notice to Hughes, shall
exercise its existing contractual right to terminate the Lockheed Martin
Contract on or prior to December 31, 1998, unless instructed to the contrary by
Hughes.

            5.20. Spring Communications. Promptly following the date hereof, HBI
shall purchase from the Company, and the Company shall sell to HBI, all of the
Company's interest in Spring USSB Communications LLC ("Spring") for a purchase
price of One Hundred Thousand Dollars ($100,000), plus an amount equal to all
capital contributions paid by the Company to Spring following the date hereof
and prior to such purchase. As part of such purchase and sale, HBI shall assume
all liabilities and obligations relating to Spring and shall indemnify and hold
the Company harmless with respect thereto. All documents relating to the
purchase of Spring and such indemnification shall be reasonably satisfactory to
Hughes and the Company.

            5.21. Confirmatory Certificates; Communications. In order to verify
the truth of the representations and warranties contained in (i) Section
3.16(b), (ii) the penultimate sentence of Section 3.6 and (iii) the first

provide the Company with a list of Material Contracts as to which it desires
written confirmation to such effect from the parties to such Contracts. Hughes
shall consult with the Company regarding the content of such list and conduct
such confirmation in a reasonable manner to limit disruption to the business.
The Company shall use its reasonable best efforts to obtain such requested
written confirmations prior to the Closing Date. The Company and Hughes will
coordinate their communications to, and each participate in all meetings and
discussions with, material providers of programming and other suppliers to the
Company; provided, that the Company may continue its day-to-day operational
activities with such parties in the ordinary course of business. Without
limiting the foregoing, Hughes shall direct, and the Company shall assist and
cooperate with respect to, the development of any new programming arrangements
to be effective from and after the Closing Date, to the extent deemed necessary
or advisable by Hughes to fulfill the conditions to closing pursuant to this
Agreement, with providers of programming to the Company.

            (b) by Hughes or the Company if the Merger has not been consummated
by September 30, 1999 (the "Latest Date"); provided, that no party may terminate

U.S. Federal Trade Commission has issued or stated its intention to seek an
order, preliminary or permanent injunction, or other legal restraint or

            (d) by the Company, so long as the Company is not then in material

any representation or warranty on the part of GM or Hughes set forth in this

breach of any of their obligations hereunder, if (i) there shall have been a

in writing signed on behalf of the parties hereto.

time for the performance of any of the obligations or other acts of the other
party, (ii) waive any inaccuracies in the representations and warranties of the
other party contained herein or in any document, certificate or writing
delivered pursuant hereto or (iii) waive compliance by the other party with any
of the agreements or conditions contained herein. Any agreement on the part of
either party hereto to any such extension or waiver shall be valid only if set
forth in an instrument in writing signed on behalf of such party. The failure of
either party hereto to assert any of its rights hereunder shall not constitute a
waiver of such rights.

of Hughes and no such assignment shall relieve Hughes of its obligations
hereunder if such assignee does not perform such obligations.

                              W I T N E S S E T H:

            WHEREAS, concurrently herewith, GM, Hughes and United States
Satellite Broadcasting Company, Inc., a Minnesota corporation (the "Company"),

            WHEREAS, as an inducement and a condition to entering into the
Merger Agreement, GM and Hughes have required that the Shareholders agree, and
the Shareholders have agreed, to enter into this Agreement;

            NOW, THEREFORE, in consideration of the foregoing and the mutual
premises, representations, warranties, covenants and agreements contained
herein, the parties hereto, intending to be legally bound, hereby agree as

<PAGE>
            (c) "Beneficially Own" or "Beneficial Ownership" with respect to any
securities shall mean having "beneficial ownership" of such securities (as
determined pursuant to Rule 13d-3 under the Securities Exchange Act of 1934, as
amended (the "Exchange Act")), including pursuant to any agreement, arrangement
or understanding, whether or not in writing. Without duplicative counting of the
same securities by the same holder, securities Beneficially Owned by a Person
shall include securities Beneficially Owned by all other Persons with whom such
Person would constitute a "group" as within the meanings of Section 13(d)(3) of
the Exchange Act.

            2. Provisions Concerning Company Common Stock. Each Shareholder
hereby agrees that during the period commencing on the date hereof and
continuing until the first to occur of the Effective Time or termination of the
Merger Agreement in accordance with its terms, at any meeting of the holders of
Company Common Stock, however called, or in connection with any written consent
of the holders of Company Common Stock, such Shareholder shall vote (or cause to
be voted) the shares of Company Common Stock set forth opposite such
Shareholder's name on Schedule I hereto under the caption "Option Shares"
(collectively, and subject to the last sentence of this Section 2, the "Option
Shares"), (i) in favor of the Merger, the execution and delivery by the Company
of the Merger Agreement and the approval of the terms thereof and each of the
other actions contemplated by the Merger Agreement and this Agreement and any
actions required in furtherance thereof and hereof; (ii) against any action or
agreement that would result in a breach in any respect of any covenant,
representation or warranty or any other obligation or agreement of the Company
under the Merger Agreement or this Agreement; and (iii) except as otherwise
agreed to in writing in advance by Hughes, against the following actions (other
than the Merger and the transactions contemplated by the Merger Agreement): (A)
any extraordinary corporate transaction, such as a merger, consolidation or
other business combination involving the Company or its Subsidiaries; (B) a
sale, lease or transfer of a material amount of assets of the Company or its
Subsidiaries, or a reorganization, recapitalization, dissolution or liquidation
of the Company or its Subsidiaries; (C) any change in a majority of the persons
who constitute the board of directors of the Company; (D) any change in the
present capitalization of the Company, any mandatory conversion of the Common
Stock into Class A Common Stock, or any amendment of the Company's Certificate
of Incorporation or Bylaws; (E) any other material change in the Company's
corporate structure or business; or (F) any other action involving the Company
or its Subsidiaries which is intended, or could reasonably be expected, to
impede, interfere with, delay, postpone, or materially adversely affect the
Merger and the transactions contemplated by this Agreement and the Merger
Agreement. Such Shareholder shall not enter into any agreement or understanding
with any person or entity the effect of which would be inconsistent with or
violative of the provisions and agreements contained in this Section 2. The
number of Option Shares shall be reduced or increased after the date hereof to a
number of shares which represent 19.9% of the voting power of the issued and
outstanding shares of capital stock of the Company.


                                     2
<PAGE>
            3. Options. In order to induce GM and Hughes to enter into the
Merger Agreement, each of the Shareholders hereby grants to Hughes an
irrevocable option (each, a "Stock Option" and collectively, the "Stock
Options") to purchase the Option Shares at a purchase price per share equal to
the Share Value, payable in cash (the "Purchase Price"). The Share Value shall
be computed in the manner provided by the Merger Agreement, except that the date
on which the Stock Options become exercisable pursuant to this Section 3 shall
be substituted for the "Closing Date" under the Merger Agreement for the
purposes of such computation. If the Merger Agreement is terminated pursuant to
Section 7.1(e), but only if the basis for such termination is the Company's
breach of Section 5.8 of the Merger Agreement, or Section 7.1(f) thereof, or any
Shareholder materially breaches any agreement contained in this Agreement, the
Stock Options shall, in any such case, become immediately exercisable with
respect to all Shareholders, in whole or in part, at any time and from time to
time upon such termination or upon GM and Hughes being informed of such breach,
as the case may be, and until the date which is 120 days after the date of such
termination or the date on which GM and Hughes are informed of such breach, as
the case may be, provided, that if at the expiration of such 120-day period the
Stock Options cannot be exercised by reason of any preliminary or final
injunction or other order issued by any court or governmental, administrative or
regulatory agency or authority prohibiting the exercise of the Stock Options
pursuant to this Agreement, or because all waiting periods under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
Act"), required for the purchase of the Option Shares upon such exercise shall
not have expired or been waived, the Stock Options shall be exercisable until 10
business days after the later of the date on which such impediment to exercise
shall have been removed or shall have become final and not subject to appeal. In
the event that Hughes wishes to exercise the Stock Options, Hughes shall send a
written notice (the "Notice") to the Shareholders identifying the place and date
(not less than two business days from the date of the Notice) for the closing of
such purchase. At such closing, Hughes shall receive certificates for the Option
Shares, duly endorsed for transfer, and shall make payment therefor by wire
transfer of immediately available funds.

            4. Other Covenants, Representations and Warranties of the
Shareholders. Each Shareholder hereby covenants, represents and warrants to each
of GM and Hughes as follows:

            (a) Ownership of Shares. Such Shareholder is the record holder of or
Beneficially Owns the number of Shares of Common Stock and Class A Common Stock,
respectively, set forth opposite such Shareholder's name on Schedule I hereto.
On the date hereof, the Shares set forth opposite such Shareholder's name on
Schedule I hereto constitute all of the Shares owned of record or Beneficially
Owned by such Shareholder. Such Shareholder has sole voting power and sole power
to issue instructions with respect to the matters set forth in Section 2 hereof,
sole power of disposition, sole power of conversion,


                                     3
<PAGE>
sole power to exercise dissenters' rights and sole power to agree to all of the
matters set forth in this Agreement, in each case with respect to all of the
Shares of Common Stock and Class A Common Stock, respectively, set forth
opposite such Shareholder's name on Schedule I hereto, with no limitations,
qualifications or restrictions on such rights, subject to applicable securities
laws and the terms of this Agreement.

            (b) Power; Binding Agreement. Such Shareholder has the legal
capacity, power and authority to enter into and perform all of such
Shareholder's obligations under this Agreement. The execution, delivery and
performance of this Agreement by such Shareholder will not violate any other
agreement to which such Shareholder is a party including, without limitation,
any voting agreement, shareholders agreement or voting trust. In addition, if
such Shareholder is a corporation, the execution and delivery of this Agreement
and the consummation of the transactions contemplated hereby (i) have been duly
authorized by the board of directors and stockholders of such Shareholder, and
(ii) do not and will not violate any provision of the certificate or articles of
incorporation or by-laws of such Shareholder. This Agreement has been duly and
validly executed and delivered by such Shareholder and constitutes a valid and
binding agreement of such Shareholder, enforceable against such Shareholder in
accordance with its terms. There is no beneficiary or holder of a voting trust
certificate or other interest of any trust of which such Shareholder is Trustee
whose consent is required for the execution and delivery of this Agreement or
the consummation by such Shareholder of the transactions contemplated hereby. If
such Shareholder is married and such Shareholder's Shares constitute community
property, this Agreement has been duly authorized, executed and delivered by,
and constitutes a valid and binding agreement of, such Shareholder's spouse,
enforceable against such person in accordance with its terms.

            (c) No Conflicts. Except for filings, permits, authorizations,
consents and approvals under the HSR Act and the Communications Act, if
applicable, (A) no filing with, and no permit, authorization, consent or
approval of, any state or federal public body or authority is necessary for the
execution of this Agreement by such Shareholder and the consummation by such
Shareholder of the transactions contemplated hereby and (B) none of the
execution and delivery of this Agreement by such Shareholder, the consummation
by such Shareholder of the transactions contemplated hereby or compliance by
such Shareholder with any of the provisions hereof shall (1) conflict with or
result in any breach of any applicable organizational documents applicable to
such Shareholder, (2) result in a violation or breach of, or constitute (with or
without notice or lapse of time or both) a default (or give rise to any third
party right of termination, cancellation, material modification or acceleration)
under any of the terms, conditions or provisions of any note, bond, mortgage,
indenture, license, contract, commitment, arrangement, understanding, agreement
or other instrument or obligation of any kind to which such Shareholder is a
party or by which such Shareholder or any of such Shareholder's properties or
assets may be bound, or (3) violate


                                     4
<PAGE>
any order, writ, injunction, decree, judgment, order, statute, rule or
regulation applicable to such Shareholder or any of such Shareholder's
properties or assets.

            (d) No Encumbrances. Except as applicable in connection with the
transactions contemplated hereby, such Shareholder's Shares and the certificates
representing such Shares are now, and at all times during the term hereof will
be, held by such Shareholder, or by a nominee or custodian for the benefit of
such Shareholder, free and clear of all liens, claims, security interests,
proxies, voting trusts or agreements, understandings or arrangements or any
other encumbrances whatsoever, except for any such encumbrances or proxies
arising hereunder in favor of GM.

            (e) No Finder's Fees. No broker, investment banker, financial
adviser or other person is entitled to any broker's, finder's, financial
adviser's or other similar fee or commission in connection with the transactions
contemplated hereby based upon arrangements made by or on behalf of such
Shareholder.

            (f) No Solicitation. No Shareholder shall, in his or its capacity as
such, directly or indirectly, solicit (including by way of furnishing
information) or respond to any inquiries or the making of any proposal by any
person or entity (other than Hughes or any affiliate of Hughes) with respect to
the Company that constitutes an Acquisition Proposal. If any Shareholder
receives any such inquiry or proposal, then such Shareholder shall promptly
inform Hughes of the existence thereof. Each Shareholder will immediately cease
and cause to be terminated any existing activities, discussions or negotiations
with any parties conducted heretofore with respect to any of the foregoing.

            (g) Restriction on Transfer of Shares, Proxies and Non-Interference.
Beginning on the date hereof and ending on the last date the Stock Options are
exercisable pursuant to Section 3 hereof, except as contemplated by this
Agreement or the Merger Agreement, no Shareholder shall, directly or indirectly,
(i) offer for sale, sell, transfer, tender, pledge, encumber, assign or
otherwise dispose of, or enter into any contract, option or other arrangement or
understanding with respect to or consent to the offer for sale, sale, transfer,
tender, pledge, encumbrance, assignment or other disposition of, any or all of
such Shareholder's Option Shares or any interest therein; (ii) except as
contemplated by this Agreement, grant any proxies or powers of attorney, deposit
any Option Shares into a voting trust or enter into a voting agreement with
respect to any Option Shares; or (iii) take any action that would make any
representation or warranty of such Shareholder contained herein untrue or
incorrect or have the effect of preventing or disabling such Shareholder from
performing such Shareholder's obligations under this Agreement. Each Shareholder
agrees with, and covenants to, Hughes that beginning on the date hereof and
ending on the last date the Stock Options are exercisable pursuant to Section 3
hereof, such Shareholder shall not request that the Company register the
transfer (book-entry or otherwise) of any certificate or


                                     5
<PAGE>
uncertificated interest representing any of such Shareholder's Option Shares,
unless such transfer is made in compliance with this Agreement (including the
provisions of Section 2 hereof).

            (h) Restriction on Transfer of Acquiror Stock. Each Shareholder
understands that such Shareholder may be deemed to be an "affiliate" of the
Company within the meaning of Rule 145 promulgated under the Securities Act of
1933, as amended (the "Securities Act"), and that the transfer of the shares of
Acquiror Stock acquired by such Shareholder in the Merger may only be made as
permitted by, and in accordance with, Rule 145 or any other applicable exemption
from registration under the Securities Act. In addition, each Shareholder
covenants to GM and Hughes that such Shareholder, in connection with any
underwritten offering of Acquiror Stock occurring within two years of the
Effective Time, will sign a customary "lock-up" agreement restricting the
transfer of the shares of Acquiror Stock held by it during the pendency of such
offering; provided that such Shareholder shall not be required to agree to any
transfer restrictions more burdensome than those to which GM or its Affiliates
agree in connection with such offering.

            (i) Waiver of Dissenters' Rights. Each Shareholder hereby waives any
rights to dissent from the Merger that such Shareholder may have under Sections
302A.471 and 302A.473 of the Minnesota Business Corporation Act (the "MBCA").
Each Shareholder acknowledges that such Shareholder has received from counsel to
the Company a copy of Sections 302A.471 and 302A.473 of the MBCA relating to
dissenters' rights and a summary of those Sections.

            (j) Reliance by GM and Hughes. Each Shareholder understands and
acknowledges that GM and Hughes are entering into the Merger Agreement in
reliance upon such Shareholder's execution and delivery of this Agreement.

            5. Other Covenants, Representations and Warranties of GM and Hughes.
GM and Hughes hereby covenant, represent and warrant to each Shareholder as
follows:

            (a) Power; Binding Agreement. Each of GM and Hughes has the legal
capacity, power and authority to enter into and perform all of such party's
obligations under this Agreement. The execution, delivery and performance of
this Agreement by GM and Hughes will not violate any other material agreement to
which GM or Hughes is a party. In addition, the execution and delivery of this
Agreement and the consummation of the transactions contemplated hereby (i) have
been duly authorized by the board of directors and stockholders of GM and
Hughes, and (ii) do not and will not violate any provision of the certificate of
incorporation or by-laws of GM or Hughes. This Agreement has been duly and
validly executed and delivered by each of GM and Hughes and constitutes a valid
and binding agreement of such party, enforceable against such party in
accordance with its terms.


                                     6

            (b) Additional Agreements. On or prior to the Closing Date, Hughes
shall, or shall cause DIRECTV to, enter into the following agreements with HBI:

an Asset Option Agreement, substantially in the form of Exhibit B hereto (iii) a
Trademark/Trade Name Option Agreement, substantially in the form of Exhibit C

            6. Further Assurances. From time to time, at the other party's
request and without further consideration, each party hereto shall execute and
deliver such additional documents and take all such further lawful action as may
be necessary or desirable to consummate and make effective, in the most
expeditious manner practicable, the transactions contemplated by this Agreement.

            7. Termination; Expenses and Fee. (a) The covenants and agreements
contained herein with respect to the Shares shall terminate (i) in the event the
Merger Agreement is terminated in accordance with its terms, upon such
termination, except that the provisions of Section 3 hereof shall survive any
such termination and (ii) in the event the Merger is consummated, at the
Effective Time, except that the provisions of Section 4(h) hereof shall survive
any such termination, provided, in each case, that the provisions of Section 10
hereof and the last sentence of Section 5(b) hereof shall survive any
termination of this Agreement, and provided, further, that no termination of
this Agreement shall relieve any party of liability for a breach hereof.

            (b) Each party shall bear its own expenses in connection with this
Agreement and the transactions contemplated hereby. Notwithstanding the
foregoing, in the event the Merger Agreement is terminated by Hughes pursuant to
Section 7.1(f) thereof, HBI shall pay to Hughes, within one week of such
termination, $50 million in immediately available funds to an account designated
by Hughes on the date of such termination.

            8. Shareholder Capacity. No person executing this Agreement who is
or becomes during the term hereof a director or officer of the Company makes any
agreement or understanding herein in his or her capacity as such director or
officer. Each Shareholder signs solely in his or her capacity as the record and
beneficial owner of, or the trustee of a trust whose beneficiaries are the
beneficial owners of, such Shareholder's Shares.

            9. Sophistication. Each Shareholder acknowledges that such
Shareholder is an informed and sophisticated investor and, together with such
Shareholder's advisors, has undertaken such investigation as they have deemed
necessary, including the review of the


                                     7
<PAGE>
Merger Agreement and this Agreement, to enable such Shareholder to make an
informed and intelligent decision with respect to the Merger Agreement and this
Agreement and the transactions contemplated thereby and hereby.

            10. Confidentiality. Each of the parties hereto recognizes that
successful consummation of the transactions contemplated by this Agreement may
be dependent upon confidentiality with respect to the matters referred to
herein. In this connection, pending public disclosure thereof, each party hereby
agrees not to disclose or discuss such matters with anyone not a party to this
Agreement (other than such party's counsel and advisors, if any) without the
prior written consent of the other party, except for filings required pursuant
to the Exchange Act and the rules and regulations thereunder or disclosures such
party's counsel advises are necessary in order to fulfill such party's
obligations imposed by law, in which event such party shall give notice of such
disclosure to the other party as promptly as practicable so as to enable the
other party to seek a protective order from a court of competent jurisdiction
with respect thereto.

            11.   Miscellaneous.

            (a) Entire Agreement. This Agreement, the Merger Agreement, the
agreements referred to in Section 5(b) hereof and the Ancillary Agreements
constitute the entire agreement between the parties with respect to the subject
matter hereof and supersedes all other prior agreements and understandings, both
written and oral, between the parties with respect to the subject matter hereof.

            (b) Certain Events. Each Shareholder agrees that this Agreement and
the obligations hereunder shall attach to such Shareholder's Shares and shall be
binding upon any person or entity to which legal or beneficial ownership of such
Shares shall pass, whether by operation of law or otherwise, including, without
limitation, such Shareholder's heirs, guardians, administrators or successors,
provided, that following the Effective Time or termination of the Merger
Agreement, this Agreement shall not be binding on any purchaser of Shares in an
open market transaction. Notwithstanding any transfer of Shares, the transferor
shall remain liable for the performance of all obligations under this Agreement
of the transferor.

            (c) Assignment. This Agreement shall not be assigned by operation of
law or otherwise without the prior written consent of the other party, provided,
that GM or Hughes may assign, in its sole discretion, its rights and obligations
hereunder to any direct or indirect wholly owned subsidiary of GM, but no such
assignment shall relieve GM or Hughes of its obligations hereunder if such
assignee does not or cannot perform such obligations and, notwithstanding the
foregoing, GM and Hughes shall remain liable for their obligations under Section
10 hereof.

Schedule I hereto may be supplemented by GM by adding the name and other
relevant information concerning any shareholder of the Company who agrees to be

            (f) Severability. Whenever possible, each provision or portion of
any provision of this Agreement will be interpreted in such manner as to be
effective and valid under applicable law but if any provision or portion of any
provision of this Agreement is held to be invalid, illegal or unenforceable in
any respect under any applicable law or rule in any jurisdiction, such
invalidity, illegality or unenforceability will not affect any other provision
or portion of any provision in such jurisdiction, and this Agreement will be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision or portion of any provision had never been
contained herein.

            (g) Specific Performance. Each of the parties hereto recognizes and
acknowledges that a breach by it of any covenants or agreements contained in
this Agreement will cause the aggrieved party to sustain damages for which it
would not have an adequate remedy at law for money damages, and therefore each
of the parties hereto agrees that in the event of any such breach the aggrieved
party shall be entitled to the remedy of specific performance of such covenants
and agreements and injunctive and other equitable relief in addition to any
other remedy to which it may be entitled, at law or in equity.

            (h) Remedies Cumulative. All rights, powers and remedies provided
under this Agreement or otherwise available in respect hereof at law or in
equity shall be cumulative and not alternative, and the exercise of any thereof
by any party shall not preclude the simultaneous or later exercise of any other
such right, power or remedy by such party.



                                     10
<PAGE>
            (i) No Waiver. The failure of any party hereto to exercise any
right, power or remedy provided under this Agreement or otherwise available in
respect hereof at law or in equity, or to insist upon compliance by any other
party hereto with its obligations hereunder, and any custom or practice of the
parties at variance with the terms hereof, shall not constitute a waiver by such
party of its right to exercise any such or other right, power or remedy or to

                             Hughes to Acquire USSB

                   Transaction will extend DIRECTV's leadership position


      El Segundo,  CA,  December 14, 1998 - Hughes  Electronics  Corporation,  a
subsidiary of General Motors  Corporation,  announced today that it has signed a
definitive merger agreement with United States Satellite  Broadcasting  Company,
Inc.  (USSB)  (NASDAQ:  USSB) to acquire  the  business  and assets of USSB in a
transaction valued at approximately $1.3 billion, based on the Friday,  December
11, 1998 closing  price of General  Motors Class H (GMH) common stock on the New
York Stock Exchange of $38.25 per share.

      Hughes  will  combine  its  DIRECTV(R)  business  with  USSB's  assets and
business at the 101 degree West Longitude (WL) orbital slot,  which will further
strengthen DIRECTV's position as the nation's largest direct broadcast satellite
(DBS) television service. The transaction also includes USSB's three frequencies
at 110  degrees  WL  which,  pending  Federal  Communications  Commission  (FCC)
approval, DIRECTV will use to launch Spanish-languages services in 1999. DIRECTV
currently has more than 4.3 million subscribers.

      The merger will enable DIRECTV to achieve substantial cost savings through
the consolidation of duplicate operations,  and increase its average revenue per
subscriber.  The  transaction  will also allow  DIRECTV to provide a  simplified
consumer offering and expand its 185-channel programming lineup to more than 210
channels via the addition of premium  multi-channel  movie  services such as HBO
and Showtime.

      "The  combination  with USSB will not only  extend  DIRECTV's  competitive
position,   it  will  improve  its  financial   performance,   thereby  creating
significant value for GM Class H shareholders," said Michael T. Smith,  chairman
and chief executive officer of Hughes.

      "In just four years,  DIRECTV has  changed the way  millions of  Americans
watch TV and today's  announcement  marked the beginning of a new chapter in our
business"  said Eddy W.  Hartenstein,  president of DIRECTV.  "USSB has been our
partner since day one and this  transaction  reflects our ongoing  commitment to
offer consumers a superior alternative to cable television."

      "This merger will simplify the purchase  decision  process for prospective
subscribers  at  retail  and  enhance  our  programming   lineup  and  packaging
flexibility with the addition of premium programming, such as HBO and Showtime,"
added Hartenstein.  "We also believe this transaction will strengthen  DIRECTV's
brand  awareness  among  consumers,  and  increase our already  strong  customer
satisfaction   ratings  via  a  simplified  and  streamlined   customer  service
experience."



      Upon completion of the merger, DIRECTV will consolidate billing,  customer
service, remittance processing and broadcasting centers now maintained by USSB.

      "The Hubbard family members are broadcasting pioneers," added Hartenstein.
"They are  visionaries  who, along with all USSB  employees,  deserve credit for
building a successful satellite TV service, and for taking a leading role in the
development and phenomenal growth of the DBS industry."

      DIRECTV subscribers will also benefit from a new service that will utilize
USSB's three  FCC-licensed  frequencies  at 110 degrees WL. Upon the  successful
launch of the DIRECTV 1-R satellite next year, DIRECTV intends to relocate DBS 1
from 101 degrees to 110 degrees, and launch a comprehensive  package of services
targeted to the U.S. Spanish-speaking population. The services will be available
through a single  18-inch dish,  which will be capable of receiving both the new
Spanish-language  programming and DIRECTV's  current  offerings from 101 degrees
WL.

      "Our planned roll out of Spanish-language  services will deliver a diverse
lineup of quality  and  relevant  programming  to an  underserved,  but  rapidly
growing market," said Hartenstein.

      Under the agreement,  USSB  shareholders  can elect to receive cash or GMH
stock equal in value to .3775 shares of GMH stock for each outstanding  share of
USSB common stock.  This exchange  ratio is fixed as long as the  20-trading day
weighted average price of GMH stock ending two days prior to the closing date of
the  transaction  is within a range of $27.82 to $47.68 per share.  The value of
the maximum aggregate number of GMH shares to be issued cannot exceed 70% of the
total consideration to be received by all USSB shareholders.  The transaction is
intended to permit  tax-free  treatment to USSB  shareholders to the extent they
receive GMH shares.

      The merger, which is subject to USSB shareholders approval and the receipt
of  appropriate  regulatory  and  antitrust  approvals,  is expected to close in
mid-1999.
