ITEM 1.  CHANGES IN CONTROL OF REGISTRANT.

                 (a) Not applicable.

                 (b) On January 7, 1994, Blockbuster Entertainment Corporation,
a Delaware corporation (the "Registrant"), and Viacom Inc., a Delaware
corporation ("Viacom"), entered into an Agreement and Plan of Merger, dated as
of January 7, 1994 (the "Merger Agreement") under which the Registrant would
merge with and into Viacom, with Viacom being the surviving corporation (the
"Merger").  Under the terms of the Merger Agreement, as of the effective time
of the Merger, each outstanding share of the Registrant's common stock, par
value $.10 per share (the "Common Stock"), other than any shares of Common
Stock held in treasury of the Registrant, or owned by Viacom or any direct or
indirect subsidiary of Viacom or the Registrant and any dissenting shares (if
applicable), shall be converted automatically into the right to receive (i) .08
of one share of Viacom Class A Common Stock, par value $.01 per share ("Viacom
Class A Common Stock"), (ii) .60615 of one share of Viacom Class B Common
Stock, par value $.01 per share ("Viacom Class B Common Stock"), and (iii) up
to an additional .13829 of one share of Viacom Class B Common Stock, with such
amount to be determined in accordance with, and the right to receive such
shares to be evidenced by, one variable common right (a "VCR") issued by
Viacom.  In addition, employee stock options and warrants outstanding as of the
effective time of the Merger will become exercisable thereafter for the Merger
consideration described above.  Pursuant to the terms of the Registrant's stock
option plans, the vesting of the employee stock options will be accelerated in
connection with the Merger.

                 The VCRs convert into Viacom Class B Common Stock under
certain circumstances.  The number of shares into which the VCRs convert will
generally be based upon the highest 30 consecutive trading day average price of
the Viacom Class B Common Stock during the 90 trading day period prior to the
conversion date, which occurs on the first anniversary of the completion of the
Merger.  In the event that such value is more than $40.00 per share but less
than $48.00 per share, the VCRs will convert into the right to receive .05929
of a share of Viacom Class B Common Stock.  If such value is below $40.00 per
share, such number of shares will increase ratably to the maximum of .13829 of
a share of Viacom Class B Common Stock at a value of $36.00 per share or, if
such value is above $48.00 per share, the number of shares into which the VCR
will convert will decrease ratably to have no value at a price of $52.00 per
share.  The upward adjustment in the value of the VCR in excess of .05929 of a
share of Viacom Class B Common Stock will not be made in the event that, during
any 30 trading day period following the completion of the Merger

                                      2

<PAGE>   3
and prior to the conversion date, the average closing price exceeds $40.00 per
share.  In the event that during any such period such average price exceeds
$52.00 per share, the VCR will terminate.

                 Consummation of the Merger is subject to certain conditions,
including, among other things, approval of the Merger by the stockholders of
the Registrant and Viacom, the expiration or termination of the waiting period
under the Hart-Scott-Rodino Antitrust Improvement Act of 1976, receipt of
certain regulatory approvals and confirmation that the Merger qualifies as a
tax-free reorganization for federal income tax purposes.  In addition, the
Merger Agreement provides that the Registrant will reimburse Viacom for its
transaction-related expenses if the Merger Agreement is terminated and certain
other conditions are met, up to a maximum of $50 million.

                 The foregoing description of the Merger Agreement does not
purport to be complete and is qualified in its entirety by reference to the
Merger Agreement, a copy of which is attached hereto as Exhibit 2.1.

                 In addition, the Registrant and National Amusements, Inc., the
majority stockholder of Viacom ("NAI"), have entered into a Voting Agreement,
dated as of January 7, 1994 (the "Voting Agreement"), pursuant to which NAI has
agreed to vote the shares of Viacom Class A Common Stock held by it in favor of
the Merger and the Merger Agreement at any meeting of the stockholders of
Viacom and in any action by consent of the stockholders of Viacom.

                 A copy of the Voting Agreement is attached hereto as Exhibit
99.2 and the summary of the Voting Agreement set forth herein is qualified in
its entirety by reference thereto.

ITEM 5.  OTHER EVENTS.

                 Concurrently with the execution of the Merger Agreement, the
Registrant and Viacom entered into a subscription agreement, dated as of
January 7, 1994 (the "Subscription Agreement"), pursuant to which the
Registrant has agreed to subscribe for and purchase from Viacom, and Viacom has
agreed to issue and sell to Registrant, 22,727,273 shares of Viacom B Common
Stock, for an aggregate purchase price of approximately $1,250,000,000
representing a purchase price of $55.00 per share.

                 The obligations of Registrant to consummate the purchase and
sale under the Subscription Agreement are subject to, among other things,
Viacom having accepted for payment 50.1% of





                                       3
<PAGE>   4
the outstanding shares of common stock of Paramount Communications, Inc. on a
fully diluted basis pursuant to its tender offer therefor.

                 Additionally, pursuant to the Subscription Agreement, Viacom
has granted to the Registrant customary registration rights with respect to the
shares of Viacom Class B Common Stock purchased thereunder.

                 The Subscription Agreement provides that in the event the
Merger Agreement is terminated (other than by Viacom as a result of a breach of
a representation, warranty, covenant or agreement of the Registrant contained
therein), the Registrant has certain rights in the event that the Viacom Class
B Common Stock trades at levels below $55.00 per share during the one year
period after such termination.

                 The foregoing description of the Subscription Agreement does
not purport to be complete and is qualified in its entirety by reference to the
Subscription Agreement, a copy of which is attached hereto as Exhibit 99.1.

                 A copy of the joint press release, dated January 7, 1994,
relating to each of the above-described transactions is attached hereto as
Exhibit 99.3.

          1994 (this "Agreement"), between VIACOM INC., a Delaware
          corporation ("Viacom"), and BLOCKBUSTER ENTERTAINMENT
          CORPORATION, a Delaware corporation ("Blockbuster").
          
                                W I T N E S S E T H:
          
                   WHEREAS, upon the terms and subject to the conditions
          of this Agreement and in accordance with the General
          Corporation Law of the State of Delaware ("Delaware Law"),
          Blockbuster and Viacom will enter into a business combination
          transaction pursuant to which Blockbuster will merge with and
          into Viacom (the "Merger");
          
                   WHEREAS, the Board of Directors of Blockbuster has
          determined that the Merger is consistent with and in
          furtherance of the long-term business strategy of Blockbuster
          and is fair to, and in the best interests of, Blockbuster and
          the holders of Blockbuster Common Stock (as defined in Section
          2.01(a)) and has approved and adopted this Agreement and has
          approved the Merger and the other transactions contemplated
          hereby and recommended approval and adoption of this Agreement
          and approval of the Merger by the stockholders of Blockbuster;
          
                   WHEREAS, the Board of Directors of Viacom has
          determined that the Merger is consistent with and in
          furtherance of the long-term business strategy of Viacom and is
          fair to, and in the best interests of, Viacom and its
          stockholders and has approved and adopted this Agreement and

          Common Stock"); 
          
                   WHEREAS, for federal income tax purposes, it is
          intended that the Merger qualify as a reorganization under the
          provisions of Section 368(a) of the United States Internal
          Revenue Code of 1986, as amended (the "Code"); and
          
                   WHEREAS, concurrently with the execution of this
          Agreement and as an inducement to Blockbuster to enter into
          this Agreement, National Amusements, Inc., a Maryland
          corporation and the majority stockholder of Viacom ("Parent"),
          and Blockbuster have entered into a Voting Agreement (the
          "Parent Voting Agreement") pursuant to which Parent shall,
          among other things, vote its shares of Viacom Class A Common
          Stock (as defined in Section 2.01(a)) in favor of the Merger
          and the other transactions contemplated by this Agreement;

          agreements set forth in this Agreement, the parties hereto
          agree as follows:

          to the conditions set forth in this Agreement, and in
          accordance with Delaware Law, at the Effective Time (as defined
          in Section 1.03), Blockbuster shall be merged with and into
          Viacom.  As a result of the Merger, the separate corporate
          existence of Blockbuster shall cease and Viacom shall continue
          as the surviving corporation of the Merger (the "Surviving
          Corporation").
          
                   SECTION 1.02.  Closing.  Unless this Agreement shall

          shall have been abandoned pursuant to Section 8.01 and subject
          to the satisfaction or waiver of the conditions set forth in
          Article VII, the consummation of the Merger will take place as
          promptly as practicable (and in any event within two business
          days) after satisfaction or waiver of the conditions set forth
          in Article VII at the offices of Shearman & Sterling, 599

          or place is agreed to in writing by the parties hereto.
          
                   SECTION 1.03.  Effective Time.  As promptly as
          practicable after the satisfaction or, if permissible, waiver
          of the conditions set forth in Article VII, the parties hereto
          shall cause the Merger to be consummated by filing a
          certificate of merger (the "Certificate of Merger") with the
          Secretary of State of the State of Delaware in such form as
          required by, and executed in accordance with the relevant
          provisions of, Delaware Law (the date and time of such filing,
          or such later date or time as set forth therein,  being the
          "Effective Time").
          
                   SECTION 1.04.  Effect of the Merger.  At the Effective
          Time, the effect of the Merger shall be as provided in the
          applicable provisions of Delaware Law.  Without limiting the
          generality of the foregoing, and subject thereto, at the
          Effective Time, except as otherwise provided herein, all the
          property, rights, privileges, powers and franchises of Viacom
          and Blockbuster shall vest in the Surviving Corporation, and
          all debts, liabilities and duties

              reclassification, recapitalization, split, combination or
              exchange of shares, the Exchange Ratios shall be

              shall automatically be canceled and retired and shall cease
              to exist, and each certificate previously evidencing any
              such shares shall thereafter represent the right to
              receive, upon the surrender of such certificate in
              accordance with the provisions of Section 2.02,
              certificates evidencing (i) such number of whole shares of
              Viacom Common Stock into which such Blockbuster Common
              Stock was converted in accordance with the Class A and
              Class B Exchange Ratios and (ii) such number of VCRs into
              which such Blockbuster Common Stock was converted in

              such certificates previously evidencing such shares of
              Blockbuster Common Stock outstanding immediately prior to
              the Effective Time shall cease to have any rights with
              respect to such shares of Blockbuster Common Stock except
              as otherwise provided herein or by law.  No fractional
              share of Viacom Common Stock shall be issued; and, in lieu
              thereof, a cash payment shall be made pursuant to Section
              2.02(d).
          
                   (b)  Each share of Blockbuster Common Stock held in
              the treasury of Blockbuster and each share of Blockbuster
              Common Stock owned by Viacom or any direct or indirect
              wholly owned subsidiary of Viacom or of Blockbuster
              immediately prior to the Effective Time shall automatically
              be canceled and extinguished without any conversion thereof
              and no payment shall be made with respect thereto.
          
                   SECTION 2.02.  Exchange of Certificates and Cash.  (a) 
          Exchange Agent.  Viacom shall deposit, or shall cause to be
          deposited, with or for the account of a bank or trust company
          designated by Viacom, which shall be reasonably satisfactory to

          with this Article II, through the Exchange Agent, at the
          Effective Time, (i) certificates evidencing the shares of
          Viacom Common Stock and the VCRs issuable pursuant to
          Section 2.01 in exchange for outstanding shares of Blockbuster
          Common Stock and (ii) upon the request of the Exchange Agent,
          cash in an amount sufficient to make any cash payment due under
          Section 2.02(d) (such certificates for shares of Viacom Common
          Stock, together with any dividends or distributions with
          respect thereto, the VCRs and cash being hereafter collectively
          referred to as the "Exchange Fund").  The Exchange Agent shall,
          pursuant to irrevocable instructions, deliver the Viacom Common
          Stock and VCRs

          contemplated to be issued pursuant to Section 2.01 out of the
          Exchange Fund to holders of shares of Blockbuster Common Stock. 
          Except as contemplated by Section 2.02(d) hereof, the Exchange
          Fund shall not be used for any other purpose.  Any interest,
          dividends or other income earned on the investment of cash or
          other property held in the Exchange Fund shall be for the
          account of Viacom.
          
                   (b)  Exchange Procedures.  As soon as reasonably
          practicable after the Effective Time, Viacom will instruct the
          Exchange Agent to mail to each holder of record of a
          certificate or certificates which immediately prior to the
          Effective Time evidenced outstanding shares of Blockbuster
          Common Stock (other than Dissenting Shares, if applicable) (the
          "Certificates") (i) a letter of transmittal (which shall
          specify that delivery shall be effected, and risk of loss and
          title to the Certificates shall pass, only upon proper delivery
          of the Certificates to the Exchange Agent and shall be in such
          form and have such other provisions as Viacom may reasonably
          specify) and (ii) instructions to effect the surrender of the
          Certificates in exchange for the certificates evidencing shares
          of Viacom Common Stock and the VCRs and cash (if any).  Upon
          surrender of a Certificate for cancellation to the Exchange
          Agent together with such letter of transmittal, duly executed,
          and such other customary documents as may be required pursuant
          to such instructions, the holder of such Certificate shall be
          entitled to receive in exchange therefor (A) certificates
          evidencing that number of whole shares of Viacom Common Stock
          and VCRs that such holder has the right to receive in
          accordance with the Exchange Ratios in respect of the shares of
          Blockbuster Common Stock formerly evidenced by such
          Certificate, (B) any dividends or other distributions to which
          such holder is entitled pursuant to Section 2.02(c) and (C)
          cash in lieu of fractional shares of Viacom Common Stock to
          which such holder is entitled pursuant to Section 2.02(d) (the
          shares of Viacom Common Stock, the VCRs and the dividends,
          distributions and cash described in clauses (A), (B) and (C)
          being, collectively, the "Merger Consideration"), and the
          Certificate so surrendered shall forthwith be canceled.  In the
          event of a transfer of ownership of shares of Blockbuster
          Common Stock that is not registered in the transfer records of
          Blockbuster, shares of Viacom Common Stock and VCRs may be
          issued and paid in accordance with this Article II to a
          transferee if the Certificate evidencing such shares of
          Blockbuster Common Stock is presented to the Exchange Agent,
          accompanied by all documents required to evidence and effect
          such transfer and by evidence that any applicable stock
          transfer taxes have been paid.  Until surrendered as
          contemplated by this Section 2.02, each Certificate shall be

          deemed at any time after the Effective Time to evidence only
          the right to receive upon such surrender the Merger
          Consideration.  
          
                   (c)  Distributions with Respect to Unexchanged Shares
          of Viacom Common Stock.  No dividends or other distributions
          declared or made after the Effective Time with respect to
          Viacom Common Stock with a record date after the Effective Time
          shall be paid to the holder of any unsurrendered Certificate
          with respect to the shares of Viacom Common Stock they are
          entitled to receive until the holder of such Certificate shall
          surrender such Certificate.  
          
                   (d)  Fractional Shares.  No fraction of a share of
          Viacom Common Stock shall be issued in the Merger.  In lieu of
          any such fractional shares, each holder of Blockbuster Common
          Stock upon surrender of a Certificate for exchange pursuant to
          this Section 2.02 shall be paid an amount in cash (without
          interest), rounded to the nearest cent, determined by
          multiplying (i) the per share closing price on the American
          Stock Exchange ("AMEX") of Viacom Class A Common Stock or
          Viacom Class B Common Stock, as the case may be, on the date of
          the Effective Time (or, if shares of Viacom Class A Common
          Stock or Viacom Class B Common Stock, as the case may be, do
          not trade on the AMEX on such date, the first date of trading
          of such Viacom Common Stock on the AMEX after the Effective
          Time) by (ii) the fractional interest to which such holder
          would otherwise be entitled (after taking into account all
          shares of Blockbuster Common Stock then held of record by such
          holder).  
          
                   (e)  Termination of Exchange Fund.  Any portion of the
          Exchange Fund that remains undistributed to the holders of
          Blockbuster Common Stock for six months after the Effective
          Time shall be delivered to Viacom, upon demand, and any holders
          of Blockbuster Common Stock who have not theretofore complied
          with this Article II shall thereafter look only to Viacom for
          the Merger Consideration to which they are entitled pursuant to
          this Article II.
          
                   (f)  No Liability.  Neither Viacom nor Blockbuster
          shall be liable to any holder of shares of Blockbuster Common
          Stock for any such shares of Viacom Common Stock (or dividends
          or distributions with respect thereto) or VCRs from the
          Exchange Fund delivered to a public official pursuant to any
          applicable abandoned property, escheat or similar law.
          
                   (g)  Withholding Rights.  Viacom or the Exchange Agent
          shall be entitled to deduct and withhold from the consideration
          otherwise payable pursuant to this Agreement to 

                                      6

          any holder of shares of Blockbuster Common Stock such amounts
          as Viacom 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 Viacom or the
          Exchange Agent, such withheld amounts shall be treated for all
          purposes of this Agreement as having been paid to the holder of
          the shares of Blockbuster Common Stock in respect of which such
          deduction and withholding was made by Viacom or the Exchange
          Agent.
          
                   SECTION 2.03.  Stock Transfer Books.  At the Effective
          Time, the stock transfer books of Blockbuster shall be closed,
          and there shall be no further registration of transfers of
          shares of Blockbuster Common Stock thereafter on the records of
          Blockbuster.  On or after the Effective Time, any Certificates
          presented to the Exchange Agent or Viacom for any reason shall
          be converted into the Merger Consideration.  
          
                   SECTION 2.04.  Stock Options.  At the Effective Time,
          Blockbuster's obligations with respect to each outstanding
          Blockbuster Stock Option (as defined in Section 3.03) to
          purchase shares of Blockbuster Common Stock, as amended in the
          manner described in the following sentence, shall be assumed by
          Viacom.  The Blockbuster Stock Options so assumed by Viacom
          shall continue to have, and be subject to, the same terms and
          conditions as set forth in the stock option plans and
          agreements pursuant to which such Blockbuster Stock Options
          were issued as in effect immediately prior to the Effective
          Time, except that each such Blockbuster Stock Option shall be
          exercisable for (A) that number of whole shares of (i) Viacom
          Class A Common Stock equal to the product of the number of
          shares of Blockbuster Common Stock covered by such Blockbuster
          Stock Option immediately prior to the Effective Time multiplied
          by the Class A Exchange Ratio and rounded up to the nearest
          whole number of shares of Viacom Class A Common Stock and (ii)
          Viacom Class B Common Stock equal to the product of the number
          of shares of Blockbuster Common Stock covered by such
          Blockbuster Stock Option immediately prior to the Effective
          Time multiplied by the Class B Exchange Ratio and rounded up to
          the nearest whole number of shares of Viacom Class B Common
          Stock and (B) that number of VCRs equal to the product of the
          number of shares of Blockbuster Common Stock covered by such
          Blockbuster Stock Option immediately prior to the Effective
          Time multiplied by the VCR Exchange Ratio.  Each warrant held by
          employees or directors of Blockbuster shall be converted into a 
          Viacom warrant on the same terms and conditions except that each
          such warrant shall be exercisable for (A) that number of whole
          shares of (i) Viacom Class A Common Stock equal to the product 
          of the number of shares of Blockbuster Common Stock covered by
          such warrant immediately prior to the Effective Time multiplied by
          the Class A Exchange Ratio and rounded up to the nearest whole 
          number of shares of Viacom Class A Common Stock and (ii) Viacom
          Class B Common Stock equal to the product of the number of shares 
          of Blockbuster Common Stock covered by such warrant immediately prior
          to the Effective Time multiplied by the Class B Exchange Ratio and
          rounded up to the nearest whole number of shares of Viacom Class B
          Common Stock and (B) that number of VCRs equal to the product of the
          number of shares of Blockbuster Common Stock covered by such warrant
          immediately prior to the Effective Time multiplied by the VCR Exchange
          Ratio.  Viacom shall (i) reserve for issuance the number of shares 
          of Viacom Common Stock that will become issuable upon the exercise
          of such Blockbuster Stock Options pursuant to this Section 2.04 

                                      7

          and (ii) promptly after the Effective Time issue to each holder
          of an outstanding Blockbuster Stock Option a document
          evidencing the assumption by Viacom of Blockbuster's
          obligations with respect thereto under this Section 2.04. 
          Nothing in this Section 2.04 shall affect the schedule of
          vesting with respect to the Blockbuster Stock Options to be
          assumed by Viacom as provided in this Section 2.04; provided,
          however, that Blockbuster and Viacom shall use their best
          efforts to secure from each of the executives previously
          identified by mutual agreement of Blockbuster and Viacom (the
          "Designated Executives"), as promptly as practicable following
          the execution of this Agreement, a waiver of (i) the
          accelerated vesting of Blockbuster Stock Options held by such
          Designated Executive (such waiver to lapse (and vesting of such
          Blockbuster Stock Option to occur if such option has not
          already vested in accordance with the applicable vesting
          schedule) upon the termination of such Designated Executive's
          employment with Blockbuster or Viacom for any reason) and (ii)
          the triggering of the right of such Designated Executive to
          cause Blockbuster to acquire his Blockbuster Stock Options for
          cash, in each case resulting from the execution of this
          Agreement and the transactions contemplated hereby, in
          consideration for Blockbuster entering into an employment
          agreement acceptable to Blockbuster and Viacom with such
          Designated Executive.  In addition to the adjustment provided
          by Section 2.04, effective as of the Effective Time, the
          terms of each Blockbuster Stock Option held by a Blockbuster
          employee who as of the date hereof is not subject to the
          reporting requirements of Section 16(a) of the Exchange Act,
          and, subject, at Blockbuster's discretion, to any stockholder
          approvals it determines are necessary, any non employee director,
          shall be amended to provide that, if such Blockbuster
          employee's employment is terminated without cause, or such 
          directorship shall cease, such  Blockbuster Stock Option shall not
          expire prior to the second  anniversary of the Effective Time; 
          provided, however, that in no event shall the maximum term of such
          Blockbuster Stock Option be extended.
          
                   SECTION 2.05.  Dissenting Shares.  (a)  If provided
          for under Delaware Law, notwithstanding any other provision of
          this Agreement to the contrary, shares of Blockbuster Common
          Stock that are outstanding immediately prior to the Effective
          Time and which are held by stockholders who shall have not
          voted in favor of the Merger or consented thereto in writing
          and who shall have demanded properly in writing appraisal for
          such shares in accordance with Section 262 of Delaware Law and
          who shall not have withdrawn such demand or otherwise have
          forfeited appraisal rights (collectively, the "Dissenting
          Shares") shall not be converted into or represent the right to
          receive the Merger Consideration.  Such stockholders shall be
          entitled to receive payment of the appraised value of such
          shares of Blockbuster Common Stock held by them in accordance
          with the provisions of such 




                                      8

          Section 262, except that all Dissenting Shares held by
          stockholders who shall have failed to perfect or who
          effectively shall have withdrawn or lost their rights to
          appraisal of such shares of Blockbuster Common Stock under such
          Section 262 shall thereupon be deemed to have been converted
          into and to have become exchangeable, as of the Effective Time,
          for the right to receive, without any interest thereon, the
          Merger Consideration, upon surrender, in the manner provided in
          Section 2.02, of the certificate or certificates that formerly
          evidenced such shares of Blockbuster Common Stock.
          
                   (b)  Blockbuster shall give Viacom (i) prompt notice
          of any demands for appraisal received by Blockbuster,
          withdrawals of such demands, and any other instruments served
          pursuant to Delaware Law and received by Blockbuster and (ii)
          the opportunity to direct all negotiations and proceedings with
          respect to demands for appraisal under Delaware Law. 
          Blockbuster shall not, except with the prior written consent of
          Viacom, make any payment with respect to any demands for
          appraisal, or offer to settle, or settle, any such demands.
          
          
                                    ARTICLE III
          
                   REPRESENTATIONS AND WARRANTIES OF BLOCKBUSTER
          
                   Blockbuster hereby represents and warrants to Viacom
          that:
          
                   SECTION 3.01.  Organization and Qualification;
          Subsidiaries.  (a)  Each of Blockbuster and each Material
          Blockbuster Subsidiary (as defined below) is a corporation,
          partnership or other legal entity duly organized, validly
          existing and in good standing under the laws of the
          jurisdiction of its incorporation or organization and has the
          requisite power and authority and all necessary governmental
          approvals to own, lease and operate its properties and to carry
          on its business as it is now being conducted, except where the
          failure to be so organized, existing or in good standing or to
          have such power, authority and governmental approvals would
          not, individually or in the aggregate, have a Blockbuster
          Material Adverse Effect (as defined below).  Blockbuster and
          each Material Blockbuster Subsidiary are duly qualified or
          licensed as foreign corporations to do business, and are in
          good standing, in each jurisdiction where the character of the
          properties owned, leased or operated by them or the nature of
          their business makes such qualification or licensing necessary,
          except for such failures to be so qualified or licensed and in
          good standing that would not, 






                                      9

          individually or in the aggregate, have a Blockbuster Material
          Adverse Effect.  The term "Blockbuster Material Adverse Effect"
          means any change or effect that is or would be materially
          adverse to the business, results of operations or financial
          condition of Blockbuster and the Blockbuster Subsidiaries,
          taken as a whole; provided that from and after the date on
          which the issuance and sale of shares of Viacom Class B Common
          Stock contemplated by the Subscription Agreement (the
          "Subscription Agreement") dated as of the date of this
          Agreement between Viacom and Blockbuster is consummated (the
          "Subscription Date"), the term "Blockbuster Material Adverse
          Effect", for purposes of Article III and Section 7.02(a) only,
          shall be changed to mean any change or effect that is or would
          be materially adverse to the financial condition of Blockbuster
          and the Blockbuster Subsidiaries, taken as a whole, excluding
          any changes or effects caused by changes in general economic
          conditions or changes generally affecting Blockbuster's
          industry..
          
                   (b)  Each subsidiary of Blockbuster (a "Blockbuster
          Subsidiary") that constitutes a Significant Subsidiary of
          Blockbuster within the meaning of Rule 1-02 of Regulation S-X
          of the Securities and Exchange Commission (the "SEC") is
          referred to herein as a "Material Blockbuster Subsidiary".
          
                   SECTION 3.02.  Certificate of Incorporation and
          By-Laws.  Blockbuster has heretofore made available to Viacom a
          complete and correct copy of the Certificate of Incorporation
          and the By-Laws or equivalent organizational documents, each as
          amended to date, of Blockbuster and each Material Blockbuster
          Subsidiary.  Such Certificates of Incorporation, By-Laws and
          equivalent organizational documents are in full force and
          effect.  Neither Blockbuster nor any Material Blockbuster
          Subsidiary is in violation of any provision of its Certificate
          of Incorporation, By-Laws or equivalent organizational
          documents, except for such violations that would not,
          individually or in the aggregate, have a Blockbuster Material
          Adverse Effect.
          
                   SECTION 3.03.  Capitalization.  The authorized capital
          stock of Blockbuster consists of 300,000,000 shares of
          Blockbuster Common Stock and 500,000 shares of Preferred Stock,
          par value $1.00 per share ("Blockbuster Preferred Stock").  As
          of December 31, 1993, (i) 247,487,375 shares of Blockbuster
          Common Stock were issued and outstanding, all of which were
          validly issued, fully paid and nonassessable, (ii) no shares
          were held in the treasury of Blockbuster, (iii) 11,425,584
          shares were reserved for future issuance pursuant to
          outstanding employee stock options granted pursuant to
          Blockbuster's 1987 Stock Option Plan, as amended, 1989

          Stock Option Plan, as amended, 1990 Stock Option Plan, as
          amended, 1991 Employee Director Stock Option Plan, 1991
          Non-Employee Director Stock Option Plan and any other employee
          stock option plan or program (any employee or director stock
          option issued under any such plan being a "Blockbuster Stock 
          Option") and (iv) 7,138,859 shares were reserved for future 
          issuance pursuant to the terms of outstanding warrants to 
          purchase shares of Blockbuster Common Stock.  As of the date 
          hereof, no shares of Blockbuster Preferred Stock are issued 
          and  outstanding.  Except  as  set  forth  in Section 3.03 
          of  the  Disclosure  Schedule  previously  delivered  by 
          Blockbuster  to  Viacom  (the  "Blockbuster  Disclosure
          Schedule"), or except as set forth in this Section 3.03, there
          are no options, warrants or other rights, agreements,
          arrangements or commitments of any character relating to the
          issued or unissued capital stock of Blockbuster or any Material
          Blockbuster Subsidiary or obligating Blockbuster or any
          Material Blockbuster Subsidiary to issue or sell any shares of
          capital stock of, or other equity interests in, Blockbuster or
          any Material Blockbuster Subsidiary.  All shares of Blockbuster
          Common Stock subject to issuance as aforesaid, upon issuance on
          the terms and conditions specified in the instruments pursuant
          to which they are issuable, will be duly authorized, validly
          issued, fully paid and nonassessable.  Except as set forth in
          Section 3.03 of the Blockbuster Disclosure Schedule, there are
          no material outstanding contractual obligations of Blockbuster
          or any Blockbuster Subsidiary to repurchase, redeem or
          otherwise acquire any shares of Blockbuster Common Stock or any
          capital stock of any Material Blockbuster Subsidiary, or make
          any material investment (in the form of a loan, capital
          contribution or otherwise) in, any Blockbuster Subsidiary or
          any other person.  Each outstanding share of capital stock of
          each Material Blockbuster Subsidiary is duly authorized,
          validly issued, fully paid and nonassessable and each such
          share owned by Blockbuster or another Blockbuster Subsidiary is
          free and clear of all security interests, liens, claims,
          pledges, options, rights of first refusal, agreements,
          limitations on Blockbuster's or such other Blockbuster
          Subsidiary's voting rights, charges and other encumbrances of
          any nature whatsoever.
          
                   SECTION 3.04.  Authority Relative to this Agreement. 
          Blockbuster has all necessary power and authority to execute
          and deliver this Agreement, to perform its obligations

          contemplated hereby.  The execution and delivery of this
          Agreement by Blockbuster and the consummation by Blockbuster of
          the transactions contemplated hereby have been duly and validly
          authorized by all necessary corporate action and no other
          corporate proceedings on the part of Blockbuster are necessary
          to authorize this Agreement or to consummate the transactions
          contemplated herein (other than, with respect to the Merger,
          the approval and adoption of this Agreement by the holders of a
          majority of the then outstanding shares of Blockbuster Common
          Stock and the filing and recordation of appropriate merger
          documents as required by Delaware Law).  This Agreement has
          been duly and validly executed and delivered by Blockbuster
          and, assuming the due authorization, execution and delivery by
          Viacom, constitutes a legal, valid and binding obligation of
          Blockbuster, enforceable against Blockbuster in accordance with
          its terms, subject to the effect of any applicable bankruptcy,
          reorganization, insolvency, moratorium or similar laws
          affecting creditors' rights generally and subject, as to
          enforceability, to the effect of general principles of equity
          (regardless of whether such enforceability is considered in a
          proceeding in equity or at law).  Blockbuster has taken all
          appropriate actions so that the restrictions on business
          combinations contained in Section 203 of Delaware Law and
          Article 6 of Blockbuster's Certificate of Incorporation will
          not apply with respect to or as a result of the transactions
          contemplated herein or related hereto.
          
                   SECTION 3.05.  No Conflict; Required Filings and
          Consents.  (a)  Except as set forth in Section 3.05 of the
          Blockbuster Disclosure Schedule, the execution and delivery of
          this Agreement by Blockbuster do not, and the performance of
          the transactions contemplated herein by Blockbuster will not,
          (i) conflict with or violate the Certificate of Incorporation
          or By-Laws or equivalent organizational documents of
          Blockbuster or any Material Blockbuster Subsidiary, (ii)
          conflict with or violate any law, rule, regulation, order,
          judgment or decree applicable to Blockbuster or any Blockbuster
          Subsidiary or by which any property or asset of Blockbuster or
          any Blockbuster Subsidiary is bound or affected, or (iii)
          result in any breach of or constitute a default (or an event
          which with notice or lapse of time or both would become a
          default) under, result in the loss of a material benefit under,
          or give to others any right of termination, amendment,
          acceleration or cancellation of, or result in the creation of a
          lien or other encumbrance on any property or asset of
          Blockbuster or any Blockbuster Subsidiary pursuant to, any
          note, bond, mortgage, indenture, contract, agreement, lease,
          license, permit, franchise or other instrument or obligation

          or by which Blockbuster or any Blockbuster Subsidiary or any
          property or asset of Blockbuster or any Blockbuster Subsidiary
          is bound or affected, except, in the case of clauses (ii) and
          (iii), for any such conflicts, violations, breaches, defaults
          or other occurrences which would not prevent or delay
          consummation of the Merger in any material respect, or
          otherwise prevent Blockbuster from performing its obligations
          under this Agreement in any material respect, and would not,
          individually or in the aggregate, have a Blockbuster Material
          Adverse Effect.
          
                   (b)  The execution and delivery of this Agreement by
          Blockbuster do not, and the performance of this Agreement by
          Blockbuster will not, require any consent, approval,
          authorization or permit of, or filing with or notification to,
          any governmental or regulatory authority, domestic or foreign
          (each a "Governmental Entity"), except (i) for (A) applicable
          requirements, if any, of the Securities Exchange Act of 1934,
          as amended (the "Exchange Act"), the Securities Act of 1933, as
          amended (the "Securities Act"), state securities or "blue sky"
          laws ("Blue Sky Laws") and state takeover laws, (B) the
          pre-merger notification requirements of the Hart-Scott-Rodino
          Antitrust Improvements Act of 1976, as amended, and the rules
          and regulations thereunder (the "HSR Act"), (C) applicable
          requirements of the Investment Canada Act of 1985 and the
          Competition Act (Canada), (D) filing and recordation of
          appropriate merger documents as required by Delaware Law and
          (E) any non-United States competition, antitrust and investment
          laws and (ii) where failure to obtain such consents, approvals,
          authorizations or permits, or to make such filings or
          notifications, would not prevent or delay consummation of the
          Merger in any material respect, or otherwise prevent
          Blockbuster from performing its obligations under this
          Agreement in any material respect, and would not, individually
          or in the aggregate, have a Blockbuster Material Adverse
          Effect.  
          
                   SECTION 3.06.  Compliance.  Except as set forth in
          Section 3.06 of the Blockbuster Disclosure Schedule, neither
          Blockbuster nor any Blockbuster Subsidiary is in conflict with,
          or in default or violation of, (i) any law, rule, regulation,
          order, judgment or decree (including, without limitation, laws,
          rules and regulations relating to franchises) applicable to
          Blockbuster or any Blockbuster Subsidiary or by which any
          property or asset of Blockbuster or any Blockbuster Subsidiary
          is bound or affected, or (ii) any note, bond, mortgage,
          indenture, contract, agreement, lease, license, permit,
          franchise or other instrument or

          is a party or by which Blockbuster or any Blockbuster
          Subsidiary or any property or asset of Blockbuster or any
          Blockbuster Subsidiary is bound or affected, except for any
          such conflicts, defaults or violations that would not,
          individually or in the aggregate, have a Blockbuster Material
          Adverse Effect.
          
                   SECTION 3.07.  SEC Filings; Financial Statements.  (a) 
          Blockbuster has filed all forms, reports and documents required
          to be filed by it with the SEC since December 31, 1990 and has
          heretofore made available to Viacom, in the form filed with the
          SEC (excluding any exhibits thereto), (i) its Annual Reports on
          Form 10-K for the years ended December 31, 1990, 1991 and 1992,
          respectively, (ii) its Quarterly Reports on Form 10-Q for the
          periods ended March 30, 1993, June 30, 1993 and September 30,
          1993, (iii) all proxy statements relating to Blockbuster's
          meetings of stockholders (whether annual or special) held since
          January 1, 1991 and (iv) all other forms, reports and other
          registration statements (other than Quarterly Reports on Form
          10-Q not referred to in clause (ii) above and preliminary
          materials) filed by Blockbuster with the SEC since December 31,
          1990 (the forms, reports and other documents referred to in
          clauses (i), (ii), (iii) and (iv) above being referred to
          herein, collectively, as the "Blockbuster SEC Reports").  The
          Blockbuster SEC Reports and any forms, reports and other
          documents filed by Blockbuster with the SEC after the date of
          this Agreement (x) were or will be prepared in accordance with
          the requirements of the Securities Act and the Exchange Act, as
          the case may be, and the rules and regulations thereunder and
          (y) did not at the time they were filed, or will not at the
          time they are filed, 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 made
          therein, in the light of circumstances under which they were
          made, not misleading.  No Material Blockbuster Subsidiary,
          except for Spelling Entertainment Group Inc., a Florida
          corporation ("Spelling"), is required to file any form, report
          or other document with the SEC.
          
                   (b)  Spelling has filed all forms, reports and
          documents required to be filed by it with the SEC since
          June 30, 1992 and Blockbuster has heretofore made available to
          Viacom, in the form filed with the SEC (excluding any exhibits
          thereto), (i) Spelling's Quarterly Reports on Form 10-Q for the
          periods ended June 30, 1993 and September 30, 1993,
          (ii) all proxy statements relating to Spelling's meetings of
          stockholders (whether annual or special) held since May 1, 1993
          and (iii) all other forms, reports and

          other registration statements (other than Quarterly Reports on
          Form 10-Q not referred to in clause (ii) above and preliminary
          materials) filed by Spelling with the SEC since May 1, 1992
          (the forms, reports and other documents referred to in clauses
          (i), (ii) and (iii) above being referred to herein,
          collectively, as the "Spelling SEC Reports").  The Spelling SEC
          Reports and any forms, reports and other documents filed by
          Spelling with the SEC after the date of this Agreement (x) were
          or will be prepared in accordance with the requirements of the
          Securities Act and the Exchange Act, as the case may be, and
          the rules and regulations thereunder and (y) did not at the
          time they were filed, or will not at the time they are filed,
          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 made therein, in
          light of the circumstances under which they were made, not
          misleading.
          
                   (c)  Each of the consolidated financial statements
          (including, in each case, any notes thereto) contained in the
          Blockbuster SEC Reports and Spelling SEC Reports was prepared
          in accordance with generally accepted accounting principles
          applied on a consistent basis throughout the periods indicated
          (except as may be indicated in the notes thereto) and each
          fairly presented the financial position, results of operations
          and cash flows of Blockbuster and the consolidated Blockbuster
          Subsidiaries or Spelling and its subsidiaries, as the case may
          be, as at the respective dates thereof and for the respective
          periods indicated therein (subject, in the case of unaudited
          statements, to normal and recurring year-end adjustments which
          were not and are not expected, individually or in the
          aggregate, to be material in amount).
          
                   (d)  Except as set forth in Section 3.07 of the
          Blockbuster Disclosure Schedule or except as and to the extent
          set forth in the Blockbuster SEC Reports filed with the SEC
          prior to the date of this Agreement, Blockbuster and the
          Blockbuster Subsidiaries do not have any liability or
          obligation of any nature (whether accrued, absolute, contingent
          or otherwise) other than liabilities and obligations which
          would not, individually or in the aggregate, have a Blockbuster
          Material Adverse Effect.
          
                   SECTION 3.08.  Absence of Certain Changes or Events. 
          Since December 31, 1992, except as set forth in Section 3.08 of
          the Blockbuster Disclosure Schedule, contemplated by this
          Agreement or disclosed in any Blockbuster SEC Report filed
          since December 31, 1992 and prior to the date of this
          Agreement, Blockbuster and the Blockbuster Subsidiaries have
          conducted their businesses only

          in the ordinary course and in a manner consistent with past
          practice and, since December 31, 1992, there has not been (i)
          any Blockbuster Material Adverse Effect, (ii) any damage,
          destruction or loss (whether or not covered by insurance) with
          respect to any property or asset of Blockbuster or any
          Blockbuster Subsidiary and having, individually or in the
          aggregate, a Blockbuster Material Adverse Effect, (iii) any
          change by Blockbuster in its accounting methods, principles or
          practices, (iv) any declaration, setting aside or payment of
          any dividend or distribution in respect of any capital stock of
          Blockbuster or any Blockbuster Subsidiary or any redemption,
          purchase or other acquisition of any of their respective
          securities other than (A) regular quarterly dividends on the
          shares of Blockbuster Common Stock not in excess of $0.025 per
          share, (B) regular quarterly dividends on the shares of the
          common stock of Spelling not in excess of $.020 per share, (C)
          dividends by a Blockbuster Subsidiary to Blockbuster and (D) to
          fund pre-established dividend reinvestment plans or (v) other
          than as set forth in Section 3.03 and pursuant to the plans,
          programs or arrangements referred to in Section 3.10 and other
          than in the ordinary course of business consistent with past
          practice, any increase in or establishment of any bonus,
          insurance, severance, deferred compensation, pension,
          retirement, profit sharing, stock option (including, without
          limitation, the granting of stock options, stock appreciation
          rights, performance awards, or restricted stock awards), stock
          purchase or other employee benefit plan, or any other increase
          in the compensation payable or to become payable to any
          officers or key employees of Blockbuster or any Blockbuster
          Subsidiary.
          
                   SECTION 3.09.  Absence of Litigation.  Except as set
          forth in Section 3.09 of the Blockbuster Disclosure Schedule or
          except as disclosed in the Blockbuster SEC Reports filed with
          the SEC prior to the date of this Agreement, there is no claim,
          action, proceeding or investigation pending or, to the best
          knowledge of Blockbuster, threatened against Blockbuster or any
          Blockbuster Subsidiary, or any property or asset of Blockbuster
          or any Blockbuster Subsidiary, before any court, arbitrator or
          administrative, governmental or regulatory authority or body,
          domestic or foreign, which, individually or in the aggregate,
          would have a Blockbuster Material Adverse Effect.  Except as
          disclosed in the Blockbuster SEC Reports filed with the SEC
          prior to the date of this Agreement, neither Blockbuster nor
          any Blockbuster Subsidiary nor any property or asset of
          Blockbuster or any Blockbuster Subsidiary is subject to any
          order, writ, judgment, injunction, decree, determination or
          award which would have, individually or in the aggregate, a
          Blockbuster Material Adverse Effect.

                   SECTION 3.10.  Employee Benefit Plans.  With respect
          to all the employee benefit plans, programs and arrangements
          maintained or contributed to by Blockbuster or any Blockbuster
          Subsidiary for the benefit of any current or former employee,
          officer or director of Blockbuster or any Blockbuster
          Subsidiary (the "Blockbuster Plans"), except as set forth in
          Section 3.10 of the Blockbuster Disclosure Schedule or the
          Blockbuster SEC Reports and except as would not, individually
          or in the aggregate, have a Blockbuster Material Adverse
          Effect:  (i) each Blockbuster Plan intended to be qualified
          under Section 401(a) of the Code has received a favorable
          determination letter from the Internal Revenue Service (the
          "IRS") that it is so qualified and nothing has occurred since
          the date of such letter that could reasonably be expected to
          affect the qualified status of such Blockbuster Plan; (ii) each
          Blockbuster Plan has been operated in all material respects in
          accordance with its terms and the requirements of applicable
          law; (iii) neither Blockbuster nor any Blockbuster Subsidiary
          has incurred any direct or indirect liability under, arising
          out of or by operation of Title IV of the Employee Retirement
          Income Security Act of 1974, as amended ("ERISA"), in
          connection with the termination of, or withdrawal from, any
          Blockbuster Plan or other retirement plan or arrangement, and
          no fact or event exists that could reasonably be expected to
          give rise to any such liability; and (iv) Blockbuster and the
          Blockbuster Subsidiaries have not incurred any liability under,
          and have complied in all material respects with, the Worker
          Adjustment Retraining Notification Act ("WARN"), and no fact or
          event exists that could give rise to liability under such act. 
          Except as set forth in Section 3.10 of the Blockbuster
          Disclosure Schedule, none of the Blockbuster Plans currently
          maintained by or contributed to by Blockbuster nor any Plan
          maintained by any entity that together with Blockbuster or the
          Blockbuster Subsidiaries would be deemed a "single employer"
          within the meaning of Section 4001(b) of ERISA (a "Blockbuster
          Affiliate Plan") is subject to Title IV of ERISA.  No
          Blockbuster Plan or Blockbuster Affiliate Plan has incurred any
          "accumulated funding deficiency" (as defined in Section 302 of
          ERISA and Section 412 of the Code), whether or not waived as of
          the most recently completed plan year of such plan.
          
                   SECTION 3.11.  Trademarks, Patents and Copyrights. 
          Blockbuster and the Blockbuster Subsidiaries own, or possess
          adequate licenses or other valid rights to use, all material
          patents, patent rights, trademarks, trademark rights, trade
          names, trade name rights, copyrights, service marks, service

          connection with the business of Blockbuster and the Blockbuster
          Subsidiaries as currently conducted, and no assertion or claim
          has been made in writing challenging the validity of any of the
          foregoing which, individually or in the aggregate, would have a
          Blockbuster Material Adverse Effect.  To the best knowledge of
          Blockbuster, the conduct of the business of Blockbuster and the
          Blockbuster Subsidiaries as currently conducted does not
          conflict in any way with any patent, patent right, license,
          trademark, trademark right, trade name, trade name right,
          service mark or copyright of any third party that, individually
          or in the aggregate, would have a Blockbuster Material Adverse
          Effect.  
          
                   SECTION 3.12.  Taxes.  Except as set forth in Section
          3.12 of the Disclosure Schedule, Blockbuster and the
          Blockbuster Subsidiaries have timely filed all federal, state,
          local and foreign tax returns and reports required to be filed
          by them through the date hereof and shall timely file all
          returns and reports required on or before the Effective Time,
          except for such returns and reports the failure of which to
          file timely would not, individually or in the aggregate, have a
          Blockbuster Material Adverse Effect.  Such reports and returns
          are and will be true, correct and complete, except for such
          failures to be true, correct and complete as would not,
          individually or in the aggregate, have a Blockbuster Material
          Adverse Effect.  Blockbuster and the Blockbuster Subsidiaries
          have paid and discharged all federal, state, local and foreign
          taxes due from them, other than such taxes that are being
          contested in good faith by appropriate proceedings and are
          adequately reserved as shown in the audited consolidated
          balance sheet of Blockbuster dated December 31, 1992 (the
          "Blockbuster 1992 Balance Sheet") and its most recent quarterly
          financial statements, except for such failures to so pay and
          discharge which would not, individually or in the aggregate,
          have a Blockbuster Material Adverse Effect.  Neither the IRS
          nor any other taxing authority or agency, domestic or foreign,
          is now asserting or, to the best knowledge of Blockbuster,
          threatening to assert against Blockbuster or any Blockbuster
          Subsidiary any deficiency or material claim for additional
          taxes or interest thereon or penalties in connection therewith
          which, if such deficiencies or claims were finally resolved
          against Blockbuster and the Blockbuster Subsidiaries would,
          individually or in the aggregate, have a Blockbuster Material
          Adverse Effect.  The accruals and reserves for taxes (including
          interest and penalties, if any, thereon) reflected in the
          Blockbuster 1992 Balance Sheet and the most recent quarterly
          financial statements are adequate in accordance

          with generally accepted accounting principles, except where the
          failure to be adequate would not have a Blockbuster Material
          Adverse Effect.  Blockbuster and the Blockbuster Subsidiaries
          have withheld or collected and paid over to the appropriate
          governmental authorities or are properly holding for such
          payment all taxes required by law to be withheld or collected,
          except for such failures to have so withheld or collected and
          paid over or to be so holding for payment which would not,
          individually or in the aggregate, have a Blockbuster Material
          Adverse Effect.  There are no material liens for taxes upon the
          assets of Blockbuster or the Blockbuster Subsidiaries, other
          than liens for current taxes not yet due and payable and liens
          for taxes that are being contested in good faith by appropriate
          proceedings.  Neither Blockbuster nor any Blockbuster
          Subsidiary has agreed to or is required to make any adjustment
          under Section 481(a) of the Code.  Neither Blockbuster nor any
          Blockbuster Subsidiary has made an election under Section
          341(f) of the Code.  For purposes of this Section 3.12, where a
          determination of whether a failure by Blockbuster or a
          Blockbuster Subsidiary to comply with the representations
          herein has a Blockbuster Material Adverse Effect is necessary,
          such determination shall be made on an aggregate basis with all
          other failures within this Section 3.12.
          
                   SECTION 3.13.  Opinion of Financial Advisor. 
          Blockbuster has received the opinion of Merrill Lynch, Pierce,
          Fenner & Smith Incorporated ("Merrill Lynch"), dated January 7,
          1994, to the effect that, as of such date, the Exhange Ratios,
          taken as a whole, are fair to the stockholders of Blockbuster
          from a financial point of view, a copy of which opinion has
          been delivered to Viacom.
          
                   SECTION 3.14.  Vote Required.  The affirmative vote of
          the holders of a majority of the outstanding shares of
          Blockbuster Common Stock is the only vote of the holders of any
          class or series of Blockbuster capital stock necessary to
          approve the Merger.
          
                   SECTION 3.15.  Brokers.  No broker, finder or
          investment banker (other than Merrill Lynch) is entitled to any
          brokerage, finder's or other fee or commission in connection
          with the transactions contemplated herein based upon
          arrangements made by or on behalf of Blockbuster.  Blockbuster
          has heretofore furnished to Viacom a complete and correct copy
          of all agreements between Blockbuster and Merrill Lynch
          pursuant to which such firm would be entitled to any payment
          relating to the transactions contemplated herein.

                                     ARTICLE IV
          
                      REPRESENTATIONS AND WARRANTIES OF VIACOM
          
                   Viacom hereby represents and warrants to Blockbuster
          that:
          
                   SECTION 4.01.  Organization and Qualification;
          Subsidiaries.  (a)  Each of Viacom and each Material Viacom
          Subsidiary (as defined below) is a corporation, partnership or
          other legal entity duly organized, validly existing and in good
          standing under the laws of the jurisdiction of its
          incorporation or organization and has the requisite power and
          authority and all necessary governmental approvals to own,
          lease and operate its properties and to carry on its business
          as it is now being conducted, except where the failure to be so
          organized, existing or in good standing or to have such power,
          authority and governmental approvals would not, individually or
          in the aggregate, have a Viacom Material Adverse Effect (as
          defined below).  Viacom and each Material Viacom Subsidiary is
          duly qualified or licensed as a foreign corporation to do
          business, and is in good standing, in each jurisdiction where
          the character of the properties owned, leased or operated by it
          or the nature of its business makes such qualification or
          licensing necessary, except for such failures to be so
          qualified or licensed and in good standing that would not,
          individually or in the aggregate, have a Viacom Material
          Adverse Effect.  The term "Viacom Material Adverse Effect"
          means any change or effect that is or would be materially
          adverse to the business, results of operations or financial
          condition of Viacom and the Viacom Subsidiaries, taken as a
          whole; provided that from and after the Subscription Date, the
          term "Viacom Material Adverse Effect", for purposes of Article
          IV and Section 7.03(a) only, shall be changed to mean any
          change or effect that is or would be materially adverse to the
          financial condition of Viacom and the Viacom Subsidiaries,
          taken as a whole, excluding any changes or effects caused by
          changes in general economic conditions or changes generally
          affecting Viacom's industry.
          
                   (b)  Each subsidiary of Viacom (a "Viacom Subsidiary")
          that constitutes a Significant Subsidiary of Viacom within the
          meaning of Rule 1-02 of Regulation S-X of the SEC is referred
          to herein as a "Material Viacom Subsidiary".
          
                   SECTION 4.02.  Certificate of Incorporation and
          By-Laws.  Viacom has heretofore made available to Blockbuster

          a complete and correct copy of the Certificate of Incorporation
          and the By-Laws or equivalent organizational documents, each as
          amended to date, of Viacom and each Material Viacom Subsidiary. 
          Such Certificates of Incorporation, By-Laws and equivalent
          organizational documents are in full force and effect.  Neither
          Viacom nor any Material Viacom Subsidiary is in violation of
          any provision of its Certificate of Incorporation, By-Laws or
          equivalent organizational documents, except for such violations
          that would not, individually or in the aggregate, have a Viacom
          Material Adverse Effect.
          
                   SECTION 4.03.  Capitalization.  The authorized capital
          stock of Viacom consists of 100,000,000 shares of Viacom
          Class A Common Stock, 150,000,000 shares of Viacom Class B
          Common Stock and 100,000,000 shares of Preferred Stock, par
          value $.01 per share ("Viacom Preferred Stock"), of which
          24,000,000 shares have been designated Series A Preferred Stock
          (the "Series A Preferred Stock") and 24,000,000 shares have
          been designated Series B Preferred Stock (the "Series B
          Preferred Stock").  As of November 30, 1993, (i) 53,449,125
          shares of Viacom Class A Common Stock and 67,345,982 shares of
          Viacom Class B Common Stock were issued and outstanding, all of
          which were validly issued, fully paid and nonassessable, (ii)
          no shares were held in the treasury of Viacom, (iii) no shares
          were held by the Viacom Subsidiaries, and (iv) 224,610 shares
          of Viacom Class A Common Stock and 3,760,297 shares of Viacom
          Class B Common Stock were reserved for future issuance pursuant
          to outstanding employee stock options or stock incentive rights
          granted pursuant to Viacom's 1989 Long-Term Management
          Incentive Plan, the Viacom Inc. Stock Option Plan for Outside
          Directors and any other employee stock option plan or program. 
          Since December 1, 1993 to the date of this Agreement, stock
          options were granted pursuant to which no shares of Viacom Class
          A Common Stock and no shares of Viacom Class B Common Stock are
          subject to issuance.  As of the date hereof, 24,000,000 shares
          of Viacom Series A Preferred Stock and 24,000,000 shares of
          Viacom Series B Preferred Stock are issued and outstanding. 
          Except as set forth in this Section 4.03 and as contemplated by
          this Agreement, there are no options, warrants or other rights,
          agreements, arrangements or commitments of any character
          relating to the issued or unissued capital stock of Viacom or
          any Material Viacom Subsidiary or obligating Viacom or any
          Material Viacom Subsidiary to issue or sell any shares of
          capital stock of, or other equity interests in, Viacom or any
          Material Viacom Subsidiary, except for (i) options granted
          since November 30, 1993 in the ordinary course consistent with
          past practice, (ii) the reservation of 8,570,400 shares of
          Class B Common

          Stock for issuance upon conversion of shares of Viacom Series A
          Preferred Stock and (iii) the reservation of 17,140,800 shares
          of Class B Common Stock for issuance upon conversion of shares
          of Series B Preferred Stock.  All shares of Viacom Common Stock
          subject to issuance as aforesaid, upon issuance on the terms
          and conditions specified in the instruments pursuant to which
          they are issuable, will be duly authorized, validly issued,
          fully paid and nonassessable.  Except as set forth in Section
          4.03 of the Disclosure Schedule previously delivered by Viacom
          to Blockbuster (the "Viacom Disclosure Schedule"), there are no
          material outstanding contractual obligations of Viacom or any
          Viacom Subsidiary to repurchase, redeem or otherwise acquire
          any shares of Viacom Common Stock or any capital stock of any
          Material Viacom Subsidiary, or make any material investment (in
          the form of a loan, capital contribution or otherwise) in, any
          Viacom Subsidiary or any other person.  Each outstanding share
          of capital stock of each Material Viacom Subsidiary is duly
          authorized, validly issued, fully paid and nonassessable and
          each such share owned by Viacom or another Viacom Subsidiary is
          free and clear of all security interests, liens, claims,
          pledges, options, rights of first refusal, agreements,
          limitations on Viacom's or such other Viacom Subsidiary's
          voting rights, charges and other encumbrances of any nature
          whatsoever.  The VCRs to be issued pursuant to the Merger will
          be duly and validly authorized by Viacom and, when issued and
          delivered pursuant to the terms of this Agreement, will be duly
          and validly issued, fully paid and nonassessable.  The shares
          of Viacom Class B Common Stock (if any) issuable pursuant to
          the terms of the VCRs will be duly authorized, validly issued,
          fully paid and nonassessable.  The VCRs constitute legal, valid
          and binding obligations of Viacom, enforceable against Viacom
          in accordance with their terms, subject to the effect of any
          applicable bankruptcy, reorganization, insolvency, moratorium
          or similar laws affecting creditors' rights generally and
          subject, as to enforceability, to the effect of general
          principles of equity (regardless of whether such enforceability
          is considered in a proceeding in equity or at law).
          
                   SECTION 4.04.  Authority Relative to this Agreement. 
          Viacom has all necessary power and authority to execute and
          deliver this Agreement, to perform its obligations hereunder
          and to consummate the transactions contemplated herein.  The
          execution and delivery of this Agreement by Viacom and the
          consummation by Viacom of the transactions contemplated herein
          have been duly and validly authorized by all necessary
          corporate action and the Parent Voting Agreement has been
          approved by the Viacom Board of

          Directors for purposes of Section 203 of Delaware Law and no
          other corporate proceedings on the part of Viacom are necessary
          to authorize this Agreement or to consummate the transactions
          contemplated herein (other than, with respect to the Merger,
          the approval by the holders of a majority of the then
          outstanding shares of Viacom Class A Common Stock of (i) this
          Agreement and the Merger and (ii) to the extent necessary, the
          amendment to Viacom's Certificate of Incorporation necessary to
          increase (x) the shares of authorized Viacom Class B Common
          Stock to a number not less than the number sufficient to
          consummate the issuance of Shares of Viacom Class B Common
          Stock contemplated under this Agreement and (y) the size of the
          Board of Directors of Viacom to a number not less than 12
          (collectively, the "Viacom Vote Matter"; and the amendments to
          Viacom's Certificate of Incorporation described in clauses (x)
          and (y) being, collectively, the "Viacom Certificate
          Amendments"), and the filing and recordation of the foregoing
          amendment to Viacom's Certificate of Incorporation and
          appropriate merger documents as required by Delaware Law). 
          This Agreement has been duly and validly executed and delivered
          by Viacom and, assuming the due authorization, execution and
          delivery by Blockbuster, constitutes a legal, valid and binding
          obligation of Viacom, enforceable against Viacom in accordance
          with its terms, subject to the effect of any applicable
          bankruptcy, reorganization, insolvency, moratorium or similar
          laws affecting creditors' rights generally and subject, as to
          enforceability, to the effect of general principles of equity
          (regardless of whether such enforceability is considered in a
          proceeding in equity or at law).
          
                   SECTION 4.05.  No Conflict; Required Filings and
          Consents.  (a)  Except as set forth in Section 4.05 of the
          Viacom Disclosure Schedule, the execution and delivery of this
          Agreement by Viacom do not, and the performance of the
          transactions contemplated herein by Viacom will not,
          (i) conflict with or violate the Certificate of Incorporation
          or By-Laws or equivalent organizational documents of Viacom or
          any Material Viacom Subsidiary, (ii) conflict with or violate
          any law, rule, regulation, order, judgment or decree applicable
          to Viacom or any Viacom Subsidiary or by which any property or
          asset of Viacom or any Viacom Subsidiary is bound or affected,
          or (iii) result in any breach of or constitute a default (or an
          event which with notice or lapse of time or both would become a
          default) under, result in the loss of a material benefit under
          or give to others any right of termination, amendment,
          acceleration or cancellation of, or result in the creation of a
          lien or other encumbrance on any property or asset of Viacom or
          any Viacom Subsidiary pursuant

          to, any note, bond, mortgage, indenture, contract, agreement,
          lease, license, permit, franchise or other instrument or
          obligation to which Viacom or any Viacom Subsidiary is a party
          or by which Viacom or any Viacom Subsidiary or any property or
          asset of Viacom or any Viacom Subsidiary is bound or affected,
          except in the case of clauses (ii) and (iii), for any such
          conflicts, violations, breaches, defaults or other occurrences
          which would not prevent or delay consummation of the Merger in
          any material respect, or otherwise prevent Viacom from
          performing its obligations under this Agreement in any material
          respect, and would not, individually or in the aggregate, have a
          Viacom Material Adverse Effect.
          
                   (b)  The execution and delivery of this Agreement by
          Viacom do not, and the performance of this Agreement by Viacom
          will not, require any consent, approval, authorization or
          permit of, or filing with or notification to, any Governmental
          Entity, except (i) for (A) applicable requirements, if any, of
          the Exchange Act, Securities Act, state securities or Blue Sky
          Laws and state takeover laws, (B) the pre-merger notification
          requirements of the HSR Act, (C) applicable requirements, if
          any, of the Communications Act, and of state and local
          governmental authorities, including state and local authorities
          granting franchises to operate cable systems, (D) applicable
          requirements of the Investment Canada Act of 1985 and the
          Competition Act (Canada), (E) filing and recordation of
          appropriate merger documents and the Viacom Certificate
          Amendments as required by Delaware Law and (F) any non-United
          States competition, antitrust and investment laws and (ii)
          where failure to obtain such consents, approvals,
          authorizations or permits, or to make such filings or
          notifications, would not prevent or delay consummation of the
          Merger in any material respect, or otherwise prevent Viacom
          from performing its obligations under this Agreement in any
          material respect, and would not, individually or in the
          aggregate, have a Viacom Material Adverse Effect.  
          
                   SECTION 4.06.  Compliance.  Neither Viacom nor any
          Viacom Subsidiary is in conflict with, or in default or
          violation of, (i) any law, rule, regulation, order, judgment or
          decree applicable to Viacom or any Viacom Subsidiary or by
          which any property or asset of Viacom or any Viacom Subsidiary
          is bound or affected, or (ii) any note, bond, mortgage,
          indenture, contract, agreement, lease, license, permit,
          franchise or other instrument or obligation to which Viacom or
          any Viacom Subsidiary is a party or by which Viacom or any
          Viacom Subsidiary or any property or asset of Viacom or any
          Viacom Subsidiary is bound or affected, except for any

          such conflicts, defaults or violations that would not,
          individually or in the aggregate, have a Viacom Material
          Adverse Effect.
          
                   SECTION 4.07.  SEC Filings; Financial Statements.  (a) 
          Viacom has filed all forms, reports and documents required to
          be filed by it with the SEC since December 31, 1990, and has
          heretofore made available to Blockbuster, in the form filed
          with the SEC (excluding any exhibits thereto), (i) its Annual
          Reports on Form 10-K for the fiscal years ended December 31,
          1990, 1991 and 1992, respectively, (ii) its Quarterly Reports
          on Form 10-Q for the periods ended March 31, 1993, June 30,
          1993 and September 30, 1993, (iii) all proxy statements
          relating to Viacom's meetings of stockholders (whether annual
          or special) held since January 1, 1991 and (iv) all other
          forms, reports and other registration statements (other than
          Quarterly Reports on Form 10-Q not referred to in clause (ii)
          above and preliminary materials) filed by Viacom with the SEC
          since December 31, 1990 (the forms, reports and other documents
          referred to in clauses (i), (ii), (iii), and (iv) above being
          referred to herein, collectively, as the "Viacom SEC Reports"). 
          The Viacom SEC Reports and any other forms, reports and other
          documents filed by Viacom with the SEC after the date of this
          Agreement (x) were or will be prepared in accordance with the
          requirements of the Securities Act and the Exchange Act, as the
          case may be, and the rules and regulations thereunder and (y)
          did not at the time they were filed, or will not at the time
          they are filed, 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 made therein, in
          the light of the circumstances under which they were made, not
          misleading.  No Material Viacom Subsidiary (other than Viacom
          International Inc., a Delaware corporation
          ("Viacom International")) is required to file any form, report
          or other document with the SEC.
          
                   (b)  Viacom International has filed all forms, reports
          and documents required to be filed by it with the SEC since
          December 31, 1992 and Viacom has heretofore made available to
          Blockbuster, in the form filed with the SEC (excluding any
          exhibits thereto), (i) Viacom International's Annual Report on
          Form 10-K for the year ended December 31, 1992, (ii) Viacom
          International's Quarterly Reports on Form 10-Q for the periods
          ended March 31, 1993, June 30, 1993 and September 30, 1993,
          (iii) all proxy statements relating to Viacom International's
          meetings of stockholders (whether annual or special) held since
          January 1, 1993 and (iv) all other forms, reports and other
          registration statements (other than Quarterly Reports on Form
          10-Q not referred to in clause

          (ii) above and preliminary materials) filed by Viacom
          International with the SEC since December 31, 1992 (the forms,
          reports and other documents referred to in clauses (i), (ii),
          (iii) and (iv) above being referred to herein, collectively, as
          the "Viacom International SEC Reports").  The Viacom
          International SEC Reports and any forms, reports and other
          documents filed by Viacom International with the SEC after the
          date of this Agreement (x) were or will be prepared in
          accordance with the requirements of the Securities Act and the
          Exchange Act, as the case may be, and the rules and regulations
          thereunder and (y) did not at the time they were filed, or will
          not at the time they are filed, 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
          made therein, in the light of the circumstances under which
          they were made, not misleading.
          
                   (c)  Each of the consolidated financial statements
          (including, in each case, any notes thereto) contained in the
          Viacom SEC Reports and the Viacom International SEC Reports was
          prepared in accordance with generally accepted accounting
          principles applied on a consistent basis throughout the periods
          indicated (except as may be indicated in the notes thereto) and
          each fairly presented the consolidated financial position,
          results of operations and cash flows of Viacom and the
          consolidated Viacom Subsidiaries or Viacom International or the
          subsidiaries of Viacom International, as the case may be, as at
          the respective dates thereof and for the respective periods
          indicated therein (subject, in the case of unaudited
          statements, to normal and recurring year-end adjustments which
          were not and are not expected, individually or in the
          aggregate, to be material in amount).
          
                   (d)  Except as and to the extent set forth in the
          Viacom SEC Reports filed with the SEC prior to the date of this
          Agreement, Viacom and the Viacom Subsidiaries do not have any
          liability or obligation of any nature (whether accrued,
          absolute, contingent or otherwise) other than liabilities and
          obligations which would not, individually or in the aggregate,
          have a Viacom Material Adverse Effect.
          
                   SECTION 4.08.  Absence of Certain Changes or Events. 
          Since December 31, 1992, except as contemplated by this
          Agreement, as set forth in Section 4.08 of the Disclosure
          Schedule or disclosed in any Viacom SEC Report filed since
          December 31, 1992 and prior to the date of this Agreement,
          Viacom and the Viacom Subsidiaries have conducted their
          businesses only in the ordinary course and in a manner
          consistent with past practice and, since December 31, 1992

<PAGE>   32
 

          
          
          there has not been (i) any Viacom Material Adverse Effect, (ii)
          any damage, destruction or loss (whether or not covered by
          insurance) with respect to any property or asset of Viacom or
          any Viacom Subsidiary and having, individually or in the
          aggregate, a Viacom Material Adverse Effect, (iii) any change
          by Viacom in its accounting methods, principles or practices,
          (iv) any declaration, setting aside or payment of any dividend
          or distribution in respect of any capital stock of Viacom or
          any Viacom Subsidiary or any redemption, purchase or other
          acquisition of any of their respective securities other than
          dividends by a Viacom Subsidiary to Viacom or (v) other than as
          set forth in Section 4.03 and pursuant to the plans, programs
          or arrangements referred to in Section 4.10, other than in the
          ordinary course of business consistent with past practice, any
          increase in or establishment of any bonus, insurance,
          severance, deferred compensation, pension, retirement, profit
          sharing, stock option (including, without limitation, the
          granting of stock options, stock appreciation rights,
          performance awards, or restricted stock awards), stock purchase
          or other employee benefit plan, or any other increase in the
          compensation payable or to become payable to any officers or
          key employees of Viacom or any Viacom Subsidiary, except for
          the establishment of the Viacom Inc. Stock Option Plan for
          Outside Directors and the grant of options to purchase an
          aggregate of 25,000 shares thereunder.
          
                   SECTION 4.09.  Absence of Litigation.  Except as
          disclosed in the Viacom SEC Reports filed with the SEC prior to
          the date of this Agreement, there is no claim, action,
          proceeding or investigation pending or, to the best knowledge
          of Viacom, threatened against Viacom or any Viacom Subsidiary,
          or any property or asset of Viacom or any Viacom Subsidiary,
          before any court, arbitrator or administrative, governmental or
          regulatory authority or body, domestic or foreign, which,
          individually or in the aggregate, would have a Viacom Material
          Adverse Effect.  Except as disclosed in the Viacom SEC Reports
          filed with the SEC prior to the date of this Agreement, neither
          Viacom nor any Viacom Subsidiary nor any property or asset of
          Viacom or any Viacom Subsidiary is subject to any order, writ,
          judgment, injunction, decree, determination or award which
          would have, individually or in the aggregate, a Viacom Material
          Adverse Effect.
          
                   SECTION 4.10.  Employee Benefit Plans.  With respect
          to all the employee benefit plans, programs and arrangements
          maintained or contributed to by Viacom or any Viacom Subsidiary
          for the benefit of any current or former employee, officer or
          director of Viacom or any Viacom Subsidiary (the "Viacom
          Plans"), except as set forth in Section 4.10 of the

          Viacom Disclosure Schedule or the Viacom SEC Reports and except
          as would not, individually or in the aggregate, have a Viacom
          Material Adverse Effect:  (i) none of the Viacom Plans is a
          multiemployer plan within the meaning of ERISA; (ii) none of
          the Viacom Plans promises or provides retiree medical or life
          insurance benefits to any person; (iii) each Viacom Plan
          intended to be qualified under Section 401(a) of the Code has
          received a favorable determination letter from the IRS that it
          is so qualified and nothing has occurred since the date of such
          letter that could reasonably be expected to affect the
          qualified status of such Viacom Plan; (iv) each Viacom Plan has
          been operated in all material respects in accordance with its
          terms and the requirements of applicable law; (v) neither
          Viacom nor any Viacom Subsidiary has incurred any direct or
          indirect liability under, arising out of or by operation of
          Title IV of ERISA in connection with the termination of, or
          withdrawal from, any Viacom Plan or other retirement plan or
          arrangement, and no fact or event exists that could reasonably
          be expected to give rise to any such liability; and (vi) Viacom
          and the Viacom Subsidiaries have not incurred any liability
          under, and have complied in all respects with, WARN, and no
          fact or event exists that could give rise to liability under
          such act.  Except as set forth in Section 4.10 of the Viacom
          Disclosure Schedule or the Viacom SEC Reports, the aggregate
          accumulated benefit obligations of each Viacom Plan subject to
          Title IV of ERISA (as of the date of the most recent actuarial
          valuation prepared for such Viacom Plan) do not exceed the fair
          market value of the assets of such Viacom Plan (as of the date
          of such valuation).
          
                   SECTION 4.11.  Trademarks, Patents and Copyrights. 
          Viacom and the Viacom Subsidiaries own, or possess adequate
          licenses or other valid rights to use, all material patents,
          patent rights, trademarks, trademark rights, trade names, trade
          name rights, copyrights, service marks, service mark rights,
          trade secrets, applications to register, and registrations for,
          the foregoing trademarks, service marks, know-how and other
          proprietary rights and information used in connection with the
          business of Viacom and the Viacom Subsidiaries as currently
          conducted, and no assertion or claim has been made in writing
          challenging the validity of any of the foregoing which,
          individually or in the aggregate, would have a Viacom Material
          Adverse Effect.  To the best knowledge of Viacom, the conduct
          of the business of Viacom and the Viacom Subsidiaries as
          currently conducted does not conflict in any way with any
          patent, patent right, license, trademark, trademark right,
          trade name, trade name right, service mark or copyright of any
          third party that,

          individually or in the aggregate, would have a Viacom Material
          Adverse Effect.  
          
                   SECTION 4.12.  Taxes.  Viacom and the Viacom
          Subsidiaries have timely filed all federal, state, local and
          foreign tax returns and reports required to be filed by them
          through the date hereof and shall timely file all returns and
          reports required on or before the Effective Time, except for
          such returns and reports the failure of which to file timely
          would not, individually or in the aggregate, have a Viacom
          Material Adverse Effect.  Such reports and returns are and will
          be true, correct and complete, except for such failures to be
          true, correct and complete as would not, individually or in the
          aggregate, have a Viacom Material Adverse Effect.  Viacom and
          the Viacom Subsidiaries have paid and discharged all federal,
          state, local and foreign taxes due from them, other than such
          taxes that are being contested in good faith by appropriate
          proceedings and are adequately reserved as shown in the audited
          consolidated balance sheet of Viacom dated December 31, 1992
          (the "Viacom 1992 Balance Sheet") and its most recent quarterly
          financial statements, except for such failures to so pay and
          discharge which would not, individually or in the aggregate,
          have a Viacom Material Adverse Effect.  Neither the IRS nor any
          other taxing authority or agency, domestic or foreign, is now
          asserting or, to the best knowledge of Viacom, threatening to
          assert against Viacom or any Viacom Subsidiary any deficiency
          or material claim for additional taxes or interest thereon or
          penalties in connection therewith which, if such deficiencies
          or claims were finally resolved against Viacom and the Viacom
          Subsidiaries, would, individually or in the aggregate, have a
          Viacom Material Adverse Effect.  The accruals and reserves for
          taxes (including interest and penalties, if any, thereon)
          reflected in the Viacom 1992 Balance Sheet and the most recent
          quarterly financial statements are adequate in accordance with
          generally accepted accounting principles, except where the
          failure to be adequate would not have a Viacom Material Adverse
          Effect.  Viacom and the Viacom Subsidiaries have withheld or
          collected and paid over to the appropriate governmental
          authorities or are properly holding for such payment all taxes
          required by law to be withheld or collected, except for such
          failures to have so withheld or collected and paid over or to
          be so holding for payment which would not, individually or in
          the aggregate, have a Viacom Material Adverse Effect.  There
          are no material liens for taxes upon the assets of Viacom or
          the Viacom Subsidiaries, other than liens for current taxes not
          yet due and payable and liens for taxes that are being
          contested in good faith by appropriate proceedings.  Neither
          Viacom nor any Viacom Subsidiary has agreed to or is required
          to make any

          adjustment under Section 481(a) of the Code.  Neither Viacom
          nor any Viacom Subsidiary has made an election under Section
          341(f) of the Code.  For purposes of this Section 4.12, where a
          determination of whether a failure by Viacom or a Viacom
          Subsidiary to comply with the representations herein has a
          Viacom Material Adverse Effect is necessary, such determination
          shall be made on an aggregate basis with all other failures
          within this Section 4.12.
          
                   SECTION 4.13.  Opinion of Financial Advisor.  Viacom
          has received the opinion of Smith Barney Shearson Inc. ("Smith
          Barney"), dated January 6, 1994, to the effect that, as of such
          date, the Merger is fair to the stockholders of Viacom from a
          financial point of view, a copy of which opinion has been
          delivered to Blockbuster.
          
                   SECTION 4.14.  Vote Required.  The affirmative vote of
          the holders of a majority of the outstanding shares of Viacom
          Class A Common Stock is the only vote of the holders of any
          class or series of Viacom capital stock necessary to approve
          the Viacom Vote Matter.
          
                   SECTION 4.15.  Brokers.  No broker, finder or
          investment banker (other than Smith Barney) is entitled to any
          brokerage, finder's or other fee or commission in connection
          with the transactions contemplated herein based upon
          arrangements made by or on behalf of Viacom.  Viacom has
          heretofore furnished to Blockbuster a complete and correct copy
          of all agreements between Viacom and Smith Barney pursuant to

          Agreement and the Effective Time, unless the other party shall
          have consented in writing (such consent not to be unreasonably
          withheld), the businesses of each of Blockbuster and Viacom and
          their respective subsidiaries shall, in all material respects,

          and records, and shall furnish such Respective Representatives
          with all financial, operating and other data and information as

                   (b)  All information obtained by Blockbuster or Viacom

                   SECTION 6.02.  Directors' and Officers'
          Indemnification and Insurance.  (a)  The Certificate of
          Incorporation and By-Laws of the Surviving Corporation shall
          contain the provisions with respect to indemnification set
          forth in the Certificate of Incorporation and By-Laws of Viacom
          on the date of this Agreement, which provisions shall not be
          amended, repealed or otherwise modified for a period of six
          years after the Effective Time in any manner that would
          adversely affect the rights thereunder of individuals who at
          any time prior to the Effective Time were directors or officers
          of Blockbuster in respect of actions or omissions occurring at
          or prior to the Effective Time (including, without limitation,
          the transactions contemplated by this Agreement), unless such
          modification is required by law.
          
                   (b)  From and after the Effective Time, the Surviving
          Corporation shall indemnify, defend and hold harmless the
          present and former officers and directors of Blockbuster
          (collectively, the "Indemnified Parties") against all losses,
          expenses, claims, damages, liabilities or amounts that are paid
          in settlement of, with the approval of the Surviving
          Corporation (which approval shall not unreasonably be
          withheld), or otherwise in connection with any claim, action,
          suit, proceeding or investigation (a "Claim"), based in whole
          or in part on the fact that such person is or was a director or
          officer of Blockbuster and arising out of actions or omissions
          occurring at or prior to the Effective Time (including, without
          limitation, the transactions contemplated by this Agreement),
          in each case to the full extent permitted under Delaware Law
          (and shall pay expenses in advance of the final disposition of
          any such action or proceeding to each Indemnified Party to the
          fullest extent permitted under

          Delaware Law, upon receipt from the Indemnified Party to whom
          expenses are advanced of the undertaking to repay such advances
          contemplated by Section 145(e) of Delaware Law).
          
                   (c)  Without limiting the foregoing, in the event any
          Claim is brought against any Indemnified Party (whether arising
          before or after the Effective Time) after the Effective Time
          (i) the Indemnified Parties may retain Blockbuster's regularly
          engaged independent legal counsel or other independent legal
          counsel satisfactory to them, provided that such other counsel
          shall be reasonably acceptable to the Surviving Corporation,
          (ii) the Surviving Corporation shall pay all reasonable fees
          and expenses of such counsel for the Indemnified Parties
          promptly as statements therefor are received and (iii) the
          Surviving Corporation will use its reasonable best efforts to
          assist in the vigorous defense of any such matter, provided
          that the Surviving Corporation shall not be liable for any
          settlement of any Claim effected without its written consent,
          which consent shall not be unreasonably withheld.  Any
          Indemnified Party wishing to claim indemnification under this
          Section 6.02 upon learning of any such Claim shall notify the
          Surviving Corporation (although the failure so to notify the
          Surviving Corporation shall not relieve the Surviving
          Corporation from any liability which the Surviving Corporation
          may have under this Section 6.02, except to the extent such
          failure materially prejudices the Surviving Corporation's
          position with respect to such claim), and shall deliver to the
          Surviving Corporation the undertaking contemplated by Section
          145(e) of Delaware Law.  The Indemnified Parties as a group may
          retain no more than one law firm (in addition to local counsel)
          to represent them with respect to each such matter unless there
          is, under applicable standards of professional conduct (as
          determined by counsel to the Indemnified Parties), a conflict
          on any significant issue between the positions of any two or
          more Indemnified Parties, in which event such additional
          counsel as may be required may be retained by the Indemnified
          Parties.
          
                   (d)  For a period of three years after the Effective
          Time, the Surviving Corporation shall cause to be maintained in
          effect the current policies of directors' and officers'
          liability insurance maintained by Blockbuster (provided that
          the Surviving Corporation may substitute therefor policies of
          at least the same coverage and amounts containing terms and
          conditions which are no less advantageous to former officers
          and directors of Blockbuster) with respect to claims arising
          from facts or events which occurred before the Effective Time;
          provided, however, that in no event shall the Surviving
          Corporation be required to expend pursuant to this Section

          6.02(d) more than an amount equal to 200% of current annual
          premiums paid by Blockbuster for such insurance (which premiums
          Blockbuster represents and warrants to be $756,000 in the
          aggregate).

                   (e)  This Section 6.02 is intended to be for the
          benefit of, and shall be enforceable by, the Indemnified
          Parties, their heirs and personal representatives and shall be
          binding on the Surviving Corporation and its respective
          successors and assigns.
          
                   SECTION 6.03.  Notification of Certain Matters. 
          Blockbuster shall give prompt notice to Viacom, and Viacom
          shall give prompt notice to Blockbuster, of (i) the occurrence,
          or non-occurrence, of any event the occurrence, or
          non-occurrence, of which would be likely to cause (x) any
          representation or warranty contained in this Agreement to be
          untrue or inaccurate or (y) any covenant, condition or
          agreement contained in this Agreement not to be complied with
          or satisfied and (ii) any failure of Blockbuster or Viacom, as
          the case may be, to comply with or satisfy any covenant,
          condition or agreement to be complied with or satisfied by it
          hereunder; provided, however, that the delivery of any notice
          pursuant to this Section 6.03 shall not limit or otherwise
          affect the remedies available hereunder to the party receiving
          such notice.
          
                   SECTION 6.04.  Tax Treatment.  Each of Blockbuster and
          Viacom will use its reasonable best efforts to cause the Merger
          to qualify as a reorganization under the provisions of Section
          368(a) of the Code and to obtain the opinions of counsel
          referred to in Sections 7.02(c) and 7.03(c).
          
                   SECTION 6.05.  Registration Statement; Joint Proxy
          Statement.  (a)  As promptly as practicable after the execution
          of this Agreement, (i) Viacom and Blockbuster shall prepare and
          file with the SEC a joint proxy statement relating to the
          meetings of Blockbuster's stockholders and holders of Viacom
          Class A Common Stock to be held in connection with the Merger
          (together with any amendments thereof or supplements thereto,
          the "Proxy Statement") and (ii) Viacom shall prepare and file
          with the SEC a registration statement on Form S-4 (together
          with all amendments thereto, the "Registration Statement") in
          which the Proxy Statement shall be included as a prospectus, in
          connection with the registration under the Securities Act of

          effect today) transaction under the Exchange Act with respect
          to any class of common stock of Viacom (any such transaction
          being a "Going Private Transaction"), unless Viacom provides in

                   (c)  No Order.  No Governmental Entity or federal or

              regulation, executive order, decree, injunction or other
              order (whether temporary, preliminary or permanent) which
              is in effect and which materially restricts, prevents or
              prohibits consummation of the Merger or any transaction
              contemplated by this Agreement; provided, however, that the
              parties shall use their reasonable best efforts to cause
              any such decree, judgment, injunction or other order to be
              vacated or lifted.

              authorizations, consents, waivers, orders or approvals
              required to be obtained, and all filings, notices or

              transactions contemplated hereunder shall have been
              obtained from, and made with, all required Governmental
              Entities except for such authorizations, consents, waivers,
              orders, approvals, filings, notices or declarations the
              failure to obtain or make which would not have a material
              adverse effect, at or after the Effective Time, on the
              financial condition (as existing immediately prior to the
              consummation of the Merger) of (i) Blockbuster and the

              Section 6.05), without giving effect to any notification to
              Viacom delivered pursuant to Section 6.03, shall be true
              and correct as of the Effective Time as though made on and
              as of the Effective Time, except (i) for changes
              specifically permitted by this Agreement and (ii) that
              those representations and warranties which address matters
              only as of a particular date shall remain true and correct
              as of such date, except in any case for such failures to be
              true and correct which would not, individually or in the
              aggregate, have a Blockbuster Material Adverse Effect. 
              Viacom shall have received a certificate of the Chief
              Executive Officer and Chief Financial Officer of
              Blockbuster to such effect.

              modified in any material respect.

              without giving effect to any notification made by Viacom to
              Blockbuster pursuant to Section 6.03, shall be true and

              such date, except in any case for such failures to be true
              and correct that would not, individually or in the

              Executive Officer and Chief Financial Officer of Viacom to
              such effect.

                         TERMINATION, AMENDMENT AND WAIVER
          
                   SECTION 8.01.  Termination.  This Agreement may be
          terminated at any time prior to the Effective Time, whether
          before or after approval of this Agreement and the Merger by
          the stockholders of Blockbuster or the approval by the
          stockholders of Viacom of the issuance of the shares of Viacom
          Common Stock in accordance with Article II:
          
                   (a)  by mutual consent of Blockbuster and Viacom;
          
                   (b)  by Viacom, upon a breach of any representation,
              warranty, covenant or agreement on the part of Blockbuster
              set forth in this Agreement, or if any representation or
              warranty of Blockbuster shall have become untrue, in either
              case such that the conditions set forth in Section 7.02(a)
              or Section 7.02(b), as the case may be, would be incapable
              of being satisfied by September 30, 1994 (or as otherwise
              extended); provided

              that, in any case, a wilful breach shall be deemed to cause
              such conditions to be incapable of being satisfied for
              purposes of this Section 8.01(b);
          
                   (c)  by Blockbuster, upon a breach of any
              representation, warranty, covenant or agreement on the part
              of Viacom set forth in this Agreement, or if any
              representation or warranty of Viacom shall have become
              untrue, in either case such that the conditions set forth
              in Section 7.03(a) or Section 7.03(b), as the case may be,
              would be incapable of being satisfied by September 30, 1994
              (or as otherwise extended); provided that, in any case, a
              wilful breach shall be deemed to cause such conditions to
              be incapable of being satisfied for purposes of this
              Section 8.01(c);
          
                   (d)  by either Viacom or Blockbuster, if any permanent
              injunction or action by any Governmental Entity preventing
              the consummation of the Merger shall have become final and
              nonappealable;
          
                   (e)  by either Viacom or Blockbuster, if the Merger
              shall not have been consummated before September 30, 1994;
              provided, however, that this Agreement may be extended by
              written notice of either Viacom or Blockbuster to a date
              not later than November 30, 1994, if the Merger shall not
              have been consummated as a direct result of Viacom or
              Blockbuster having failed, by September 30, 1994, to
              receive all required regulatory approvals or consents with
              respect to the Merger;
          
                   (f)  by either Viacom or Blockbuster, if this
              Agreement and the Merger shall fail to receive the
              requisite vote for approval and adoption by the
              stockholders of Blockbuster or, with respect to Blockbuster
              only, Viacom at the Stockholders' Meetings;
          
                   (g)  by Viacom, if (i) the Board of Directors of
              Blockbuster shall withdraw, modify or change its
              recommendation of this Agreement or the Merger in a manner
              adverse to Viacom or shall have resolved to do any of the
              foregoing; (ii) the Board of Directors of Blockbuster shall
              have recommended to the shareholders of Blockbuster a
              Competing Transaction (as defined below); (iii) a tender
              offer or exchange offer for 25% or more of the outstanding
              shares of capital stock of Blockbuster is commenced, and
              the Board of Directors of Blockbuster recommends that the
              stockholders of Blockbuster tender their shares in such
              tender or exchange offer; or (iv) any person shall have
              acquired beneficial ownership

              or the right to acquire beneficial ownership of or any
              "group" (as such term is defined under Section 13(d) of the
              Exchange Act and the rules and regulations promulgated
              thereunder) shall have been formed which beneficially owns,
              or has the right to acquire beneficial ownership of, more
              than 25% of the then outstanding shares of capital stock of
              Blockbuster; and
          
                   (h)  by Blockbuster, if the Board of Directors of
              Blockbuster (x) fails to make or withdraws or modifies its
              recommendation referred to in Section 6.05(a) if there
              exists at such time a tender offer or exchange offer or a
              proposal by a third party to acquire Blockbuster pursuant
              to a merger, consolidation, share exchange, business
              combination, tender or exchange offer or other similar
              transaction or (y) recommends to Blockbuster's stockholders
              approval or acceptance of any of the foregoing, in each
              case only if the Board of Directors of Blockbuster, after
              consultation with and based upon the advice of independent
              legal counsel (who may be such party's regularly engaged
              independent legal counsel), determines in good faith that
              such action is necessary for the Board of Directors of
              Blockbuster to comply with its fiduciary duties to
              stockholders under applicable law.
          
                   The right of any party hereto to terminate this
          Agreement pursuant to this Section 8.01 shall remain operative
          and in full force and effect regardless of any investigation
          made by or on behalf of any party hereto, any person
          controlling any such party or any of their respective officers
          or directors, whether prior to or after the execution of this
          Agreement.  For purposes of this Agreement, "Competing
          Transaction" shall mean any of the following (other than the
          transactions contemplated under the Agreement) involving a
          party hereto or any of its subsidiaries:  (i) any merger,
          consolidation, share exchange, business combination, or other
          similar transaction; (ii) any sale, lease, exchange, mortgage,

          assets of such party and its subsidiaries, taken as a whole, in
          a single transaction or series of transactions; (iii) any
          tender offer or exchange offer for 25% or more of the
          outstanding shares of capital stock of such party or the filing
          of a registration statement under the Securities Act in
          connection therewith; (iv) any person having acquired
          beneficial ownership or the right to acquire beneficial
          ownership of, or any "group" (as such term is defined under
          Section 13(d) of the Exchange Act and the rules and regulations
          promulgated thereunder) having been formed which beneficially
          owns or has the right to acquire

          shares of capital stock of such party; or (v) 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.
          
                   SECTION 8.02.  Effect of Termination.  Except as
          provided in Section 8.05 or Section 9.01, in the event of the
          termination of this Agreement pursuant to Section 8.01, this
          Agreement shall forthwith become void, there shall be no
          liability on the part of Blockbuster or Viacom or any of their
          respective officers or directors to the other and all rights
          and obligations of any party hereto shall cease; provided,
          however, that nothing herein shall relieve any party from
          liability for the wilful breach of any of its representations,

          amended by the parties hereto by action taken by or on behalf
          of their respective Boards of Directors at any time prior to
          the Effective Time; provided, however, that, after approval of

                   SECTION 8.05.  Fees, Expenses and Other Payments.  (a) 
          Subject to paragraph (b) of this Section 8.05, all
          out-of-pocket costs and expenses, including, without
          limitation, fees and disbursements of counsel, financial
          advisors and accountants, incurred by the parties hereto shall
          be borne solely and entirely by the party which has incurred

          "Expenses"); provided, however, that all costs and expenses
          related to printing, filing and mailing the

          equally by Blockbuster and Viacom.
          
                   (b)  Blockbuster agrees that if this Agreement shall
          be terminated pursuant to (i) Section 8.01(b); (ii)
          Section 8.01(f) because this Agreement and the Merger shall
          fail to receive the requisite vote for approval and adoption by
          the stockholders of Blockbuster at the meeting of stockholders
          of Blockbuster called to vote thereon and at the time of such
          meeting there shall exist a Competing Transaction; or (iii)
          Section 8.01(g)(i), (ii) or (iii) or Section 8.01(h) and at the
          time of such termination there shall exist a Competing
          Transaction and the terms of such Competing Transaction provide
          that Blockbuster's stockholders shall receive consideration
          having a higher per share value than the consideration per
          share payable to Blockbuster's stockholders under this
          Agreement then in any such event Blockbuster shall pay to
          Viacom an amount equal to Viacom's Expenses; provided, however,
          that in no event shall Blockbuster be obligated to pay any of
          Viacom's Expenses exceeding $50,000,000.  For purposes of this
          Section 8.05(b), the per share value of the consideration
          payable to the Blockbuster stockholders under this Agreement
          and under the terms of the Competing Transaction shall be the
          blended weighted average price per share determined as of the
          close of business on the business day prior to the date this
          Agreement is terminated. 
          
                   (c)  Any payment required to be made pursuant to
          Section 8.05(b) shall be made as promptly as practicable but
          not later than five business days after the delivery by Viacom
          to Blockbuster of a statement setting forth any of Viacom's
          Expenses in reasonable detail and shall be made by wire
          transfer of immediately available funds to an account
          designated by Viacom.

          and Sections 6.02 and 6.16 shall survive the Effective Time and
          those set forth in Sections 6.01(b), 8.02 and 8.05 and Article
          IX hereof shall survive termination.

          Agreement, no action taken by Viacom in connection with the
          acquisition of Paramount, or effect thereof, shall cause any
          breach of a representation, warranty or covenant under this
          Agreement.

          Agreement.
          
                   SECTION 9.05.  Severability.  If any term or other
          provision of this Agreement is invalid, illegal or incapable of
          being enforced by any rule of law or public policy, all other
          conditions and provisions of this Agreement shall nevertheless
          remain in full force and effect so long as the economic or
          legal substance of the transactions contemplated hereby is not
          affected in any manner materially adverse to any party.  Upon
          such determination that any term or other provision is invalid,
          illegal or incapable of being enforced, the parties hereto
          shall negotiate in good faith to modify this Agreement so as to
          effect the original intent of the parties as closely as
          possible to the fullest extent permitted by applicable law in
          an acceptable manner to the end that the transactions
          contemplated hereby are fulfilled to the extent possible.

                   SECTION 9.06.  Entire Agreement.  This Agreement
          (together with the Exhibit, the Blockbuster Disclosure
          Schedule, the Viacom Disclosure Schedule and the other
          documents delivered pursuant hereto) and the Confidentiality
          Agreement constitute the entire agreement of the parties and
          supersede all prior agreements and undertakings, both written
          and oral, between the parties, or any of them, with respect to
          the subject matter hereof.
          
                   SECTION 9.07.  Assignment.  This Agreement shall not
          be assigned by operation of law or otherwise.
          
                   SECTION 9.08.  Parties in Interest.  This Agreement
          shall be binding upon and inure solely to the benefit of each
          party hereto, and nothing in this Agreement, express or implied
          (other than the provisions of Section 6.02 and 6.16), is
          intended to or shall confer upon any person any right, benefit
          or remedy of any nature whatsoever under or by reason of this
          Agreement.
          
                   SECTION 9.09.  Governing Law.  Except to the extent
          that Delaware Law is mandatorily applicable to the Merger and
          the rights of the stockholders of Blockbuster and Viacom, this
          Agreement shall be governed by, and construed in accordance
          with, the laws of the State of New York, regardless of the laws
          that might otherwise govern under applicable principles of
          conflicts of law.
          
                   SECTION 9.10.  Counterparts.  This Agreement may be
          executed in one or more counterparts, and by the different
          parties hereto in separate counterparts, each of which when
          executed shall be deemed to be an original but all of which
          taken together shall constitute one and the same agreement.

                                       The B Share Value will equal the
                                       average closing price on the AMEX

                                       Viacom B Common Share during any
                                       30 consecutive trading days in the
                                       Valuation Period which yield the

                                       mentioned below, each VCR will
                                       represent a fraction of one Viacom
                                       B Common Share, such fraction to
                                       be determined based upon the B

          Viacom Inc.
          1515 Broadway
          New York, New York 10036
          
          Gentlemen:
          
                   I have been advised that as of the date of this letter
          I may be deemed to be an "affiliate" of Blockbuster
          Entertainment Corporation, a Delaware corporation (the
          "Company"), as the term "affiliate" is defined for purposes of
          paragraphs (c) and (d) of Rule 145 of the rules and regulations
          (the "Rules and Regulations") of the Securities and Exchange
          Commission (the "Commission") under the Securities Act of 1933,
          as amended (the "Act").  Pursuant to the terms of the Agreement
          and Plan of Merger dated as of January 7, 1994 (the
          "Agreement"), between Viacom Inc., a Delaware corporation
          ("Viacom"), and the Company, the Company will be merged with
          and into Viacom (the "Merger").
          
                   As a result of the Merger, I may receive (A) shares of
          (i) Class A Common Stock, par value $.01 per share, of Viacom
          (the "Viacom Class A Common Stock") and (ii) Class B Common
          Stock, par value $.01 per share, of Viacom (the "Viacom Class B
          Common Stock"; and, together with the Viacom Class A Common
          Stock, the "Viacom Common Stock") and (B) VCRs (as defined in
          the Agreement) (the VCRs, together with the Viacom Common
          Stock, being the "Viacom Securities").  I would receive such
          Viacom Securities in exchange for, respectively, shares (or
          options for shares) owned by me of common stock, par value $.10
          per share, of the Company (the "Company Common Stock").
          
                   I represent, warrant and covenant to Viacom that in
          the event I receive any Viacom Securities as a result of the
          Merger:
          
                   A.  I shall not make any sale, transfer or other
              disposition of the Viacom Securities in violation of the
              Act or the Rules and Regulations.

                   B.  I have carefully read this letter and the
              Agreement and discussed the requirements of such documents
              and other applicable limitations upon my ability to sell,
              transfer or otherwise dispose of Viacom Common Stock to the
              extent I felt necessary, with my counsel or counsel for the
              Company.
          
                   C.  I have been advised that the issuance of Viacom
              Securities to me pursuant to the Merger has been registered
              with the Commission under the Act on a Registration
              Statement Form S-4.  However, I have also been advised
              that, because at the time the Merger is submitted for a
              vote of the stockholders of the Company, (a) I may be
              deemed to be an affiliate of the Company and (b) the
              distribution by me of the Viacom Securities has not been
              registered under the Act, I may not sell, transfer or
              otherwise dispose of Viacom Securities issued to me in the
              Merger unless (i) such sale, transfer or other disposition
              is made in conformity with the volume and other limitations
              of Rule 145 promulgated by the Commission under the Act,
              (ii) such sale, transfer or other disposition has been
              registered under the Act or (iii) in the opinion of counsel
              reasonably acceptable to Viacom, such sale, transfer or
              other disposition is otherwise exempt from registration
              under the Act.
          
                   D.  I understand that Viacom is under no obligation to
              register the sale, transfer or other disposition of the
              Viacom Securities by me or on my behalf under the Act or to
              take any other action necessary in order to make compliance
              with an exemption from such registration available solely
              as a result of the Merger.
          
                   E.  I also understand that there will be placed on the
              certificates for the Viacom Securities issued to me, or any
              substitutions therefor, a legend stating in substance:

      Dear Sirs:

               1.  Subject to the terms and conditions set forth
      herein, Blockbuster Entertainment Corporation, a Delaware
      corporation (the "Purchaser"), hereby subscribes for, and
      agrees to purchase, and Viacom Inc., a Delaware corporation
      (the "Company"), agrees to issue and sell, 22,727,273 shares
      (the "Shares") of Class B Common Stock, par value $0.01 per
      share, of the Company ("Class B Common Stock"), for an
      aggregate purchase price of $1,250,000,015, representing a
      purchase price of $55.00 per Share.

               2.  (a)   The closing (the "Closing") of the purchase
      provided for in paragraph 1 shall take place at a date and time
      specified by the Company by written notice delivered to the
      Purchaser no less than two Business Days (as defined below)
      prior to such date, and following satisfaction of the
      conditions specified in paragraph 5, at the offices of Shearman
      & Sterling, 599 Lexington Avenue, New York, New York.  The date
      and time of the Closing are referred to herein as the "Closing
      Date".

               (b)  At the Closing, the Purchaser shall deliver to
      the Company $1,250,000,015 in cash by wire transfer in
      immediately available funds to an account of the Company
      designated by the Company, by notice to the Purchaser prior to
      the Closing Date, and the Company shall deliver to the
      Purchaser certificates representing the Shares, registered in
      the name of the Purchaser.

               3.  (a)   The Purchaser represents and warrants to the
      Company that:  (i) the execution and delivery of this Agreement
      by the Purchaser and the performance of its

      obligations hereunder have been duly and validly authorized by
      all necessary corporate action on the part of the Purchaser;
      (ii) this Agreement has been duly and validly executed and
      delivered by the Purchaser and, assuming the due authorization,
      execution and delivery by the Company, constitutes a legal,
      valid and binding obligation of the Purchaser, enforceable
      against the Purchaser in accordance with its terms, except as
      enforcement thereof may be limited by bankruptcy, insolvency,
      reorganization, fraudulent conveyance, moratorium or other
      similar laws relating to or affecting enforcement of creditors'
      rights generally and except as enforcement thereof is subject
      to general principles of equity (regardless of whether
      enforcement is considered in a proceeding in equity or at law);
      (iii) the execution, delivery and performance of this Agreement
      by the Purchaser and the purchase of the Shares by the
      Purchaser do not conflict with or violate or result in any
      breach of or constitute a default (or an event which with
      notice or lapse of time or both would become a default) under
      the Certificate of Incorporation or By-Laws or equivalent
      organizational documents of the Purchaser; (iv) the execution,
      delivery and performance of this Agreement by the Purchaser do
      not, and the consummation of the transactions contemplated
      hereby by the Purchaser will not, require any consent,
      approval, authorization or permit of, or filing with or
      notification to, any governmental authority with respect to the
      Purchaser, except under the Securities Exchange Act of 1934, as
      amended (the "1934 Act"); (v) the Purchaser is acquiring the
      Shares for its own account for the purpose of investment and
      not with a view to or for sale in connection with any
      distribution thereof; and (vi) the Purchaser is an "accredited
      investor" within the meaning of Rule 501 under the Securities
      Act of 1933, as amended (the "1933 Act").

               (b)  Except as set forth in this paragraph 3, the
      Purchaser makes no other representation, express or implied, to
      the Company.

               4.  (a)  The Company represents and warrants to the
      Purchaser that (i) each of the Company and each Subsidiary (as
      defined below) is a corporation, partnership or other legal
      entity duly organized, validly existing and in good standing
      under the laws of the jurisdiction of its incorporation or
      organization and has the requisite power and authority and all
      necessary governmental approvals to own, lease and operate its
      properties and to carry on its business as it is now being
      conducted, except where the failure to be so organized,
      existing or in good standing or to have such power, authority
      and governmental approvals would not, individually or in the
      aggregate, have a Material Adverse

      validly executed and delivered by the Company and, assuming the
      due authorization, execution and delivery by the Purchaser,
      constitutes a legal, valid and binding obligation of the
      Company, enforceable against the Company in accordance with its
      terms, except as enforcement thereof may be limited by
      bankruptcy, insolvency, reorganization, fraudulent conveyance,
      moratorium or other similar laws relating to or affecting
      enforcement of creditors' rights generally and except as
      enforcement thereof is subject to general principles of equity
      (regardless of whether enforcement is considered in a
      proceeding in equity or at law); (iv) the execution, delivery
      and performance of this Agreement by the Company do not, and
      the issuance of the Shares and the performance of the Company's
      obligations in accordance with the terms of this Agreement will
      not, conflict with or violate or result in any breach of or
      constitute a default (or an event which with notice or lapse of
      time or both would become a default) under (A) the Certificate
      of Incorporation or By-Laws or equivalent organizational
      documents of the Company or any Subsidiary, (B) any law, rule,
      regulation, order, judgment or decree applicable to the Company

      which is reasonably likely to have a Material Adverse Effect;
      and (xv) neither the Company nor any Subsidiary is in conflict
      with, or in default or violation of, (A) any law, rule,

      the Company or any Subsidiary or any property or asset of the
      Company or any Subsidiary is bound or affected, except for any

      change or effect that is or would be materially adverse to the
      business, results of operations or financial condition of the
      Company and its Subsidiaries, taken as a whole.

               (e)  Notwithstanding anything to the contrary in this
      paragraph 4, any change to or effect on the business, results
      of operations or financial condition of the Company and its
      Subsidiaries that results, directly or indirectly, from the
      Company's tender offer for shares of common stock of and
      proposed merger with Paramount Communications Inc. (the
      "Paramount Transaction"), shall not be considered for purposes
      of determining whether a breach has occurred of any
      representation or warranty, covenant or agreement of the
      Company contained herein.

               5.  (a)   The obligation of the Purchaser to

          material respects (other than those contained in Paragraph
          4(a)(xiii) of this Agreement, which shall be true in all
          respects) as of the Closing Date, as if made at and as of
          such date (except for any such representations and
          warranties that are expressly stated to be as of a
          different date), (C) the Company shall not be in material
          breach of any of its material




                                      6
<PAGE>   7


          obligations under the Merger Agreement as of the Closing

          certificate signed by an executive officer of the Company
          to the foregoing effect;

              (ii)  no judgment, injunction, order or decree shall

          therefor.

               (b)  The obligation of the Company to consummate the
      Closing is subject to the satisfaction (or waiver by the
      Company, at its sole discretion) of the following conditions:

               (i)  (A) the Purchaser shall have performed in all
          material respects all of its obligations hereunder required
          to be performed by it at or prior to the Closing Date, (B)
          the representations and warranties of the Purchaser
          contained in this Agreement shall be true in all material
          respects at and as of the Closing Date, as if made at and

<PAGE>   8


               (c)  Notwithstanding any other provision of this
      Agreement, if the Company shall accept shares of common stock
      of Paramount Communications Inc. for payment pursuant to its
      tender offer therefor but following the Closing shall not
      purchase such shares in accordance with the terms of such
      offer, then the Purchaser may return the Shares to the Company,
      by delivering to the Company the certificates representing the
      Shares, duly endorsed in blank, or accompanied by stock powers
      duly executed in blank, whereupon the Company shall return the
      purchase price therefor, by wire transfer in immediately
      available funds to an account of the Purchaser designated by
      the Purchaser by notice to the Company.

               6.  (a) The Purchaser acknowledges that the Shares
      have not been registered under the 1933 Act or any state
      securities law, and hereby agrees not to offer, sell or
      otherwise transfer, pledge or hypothecate such Shares unless
      and until registered under the 1933 Act and any applicable
      state securities law or unless, in the opinion of counsel
      reasonably satisfactory to the Company, such offer, sale,
      transfer, pledge or hypothecation is exempt from registration
      or is otherwise in compliance with the 1933 Act and such laws.

               (b)  Upon issuance of the Shares, and until such time
      as the same is no longer required under the applicable
      requirements of the 1933 Act, the certificates evidencing the
      Shares (and all securities issued in exchange therefor or
      substitution thereof) shall bear the following legend:

          THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED
          (THE "ACT"), OR ANY STATE SECURITIES LAWS AND MAY NOT BE
          OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR
          HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT AND
          ANY APPLICABLE STATE SECURITIES LAWS OR UNLESS, IN THE
          OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE ISSUER,
          IN FORM AND SUBSTANCE REASONABLY SATISFACTORY TO THE
          ISSUER, SUCH OFFER, SALE, TRANSFER, PLEDGE OR HYPOTHECATION
          IS EXEMPT FROM REGISTRATION OR IS OTHERWISE IN COMPLIANCE
          WITH THE ACT AND SUCH LAWS.

               7.  In addition to the provisions of paragraph 6, the
      Purchaser agrees that prior to the earlier of the termination
      of the Merger Agreement and September 30, 1994 it shall not
      offer, sell, transfer, pledge or hypothecate any of the Shares,
      except that the Shares may be pledged in connection with the
      financing of the purchase price specified in paragraph 2,
      subject to the same restrictions on alienation applicable to
      the Purchaser hereunder.

               8.  Following the Closing, the Purchaser shall have
      the registration rights, and the Company shall have the
      obligations, set forth in Annex I.  Such registration rights
      shall be assignable by the Purchaser to any party purchasing
      Shares directly from the Purchaser, but shall not be further
      assignable by such subsequent purchaser or purchasers.

               9.  (a)   The representations and warranties contained
      in this Agreement shall survive the Closing until the first
      anniversary of the Closing Date.

               (b)  The Purchaser and its Affiliates, officers,
      directors, employees, agents, successors and assigns shall be
      indemnified and held harmless by the Company for any and all
      liabilities, losses, damages, claims, costs and expenses,
      interest, awards, judgments and penalties (including, without
      limitation, reasonable attorneys' fees and expenses) (a "Loss")
      actually suffered or incurred by them, arising out of or
      resulting from the breach of any representation or warranty or
      covenant of the Company contained in this Agreement.

               (c)  The Company and its Affiliates, officers,
      directors, employees, agents, successors and assigns shall be
      indemnified and held harmless by the Purchaser for any and all
      Losses actually suffered or incurred by them, arising out of or
      resulting from the breach of any representation or warranty or
      covenant of the Purchaser contained in this Agreement.

               10.  (a)  The Purchaser agrees that neither the
      Purchaser nor any of its Affiliates shall participate in any
      transaction that, directly or indirectly, would have the effect
      of precluding or competing with the Paramount Transaction.

               (b)  The Company agrees that it shall not make any
      material change in the aggregate amount or forms of
      consideration to be paid in, or in any other material terms and
      conditions of, the Paramount Transaction from the aggregate
      amount and forms of consideration described in the amendment to
      be filed on the date hereof to the Company's Tender Offer
      Statement on Schedule 14D-1, without the prior consent of the
      Purchaser, which consent shall not be unreasonably withheld.

               (c)  The Company agrees that prior to consummation of
      the Paramount Transaction, the Company shall receive an opinion
      from Smith Barney Shearson Inc. that the consideration actually
      to be paid by the Company in such




                                      9
<PAGE>   10


      transaction is fair, from a financial point of view, to the
      Company and the stockholders of the Company, which opinion
      shall not have been withdrawn at the time the Company accepts
      shares of common stock of Paramount Communications Inc. for
      payment pursuant to its tender offer therefor.

               11.  The Purchaser, on the one hand, and the Company,
      on the other, acknowledge and agree that irreparable damage
      would occur in the event that any of the provisions of this
      Agreement were not performed in accordance with their specific
      terms or were otherwise breached.  It is accordingly agreed
      that the parties shall be entitled to equitable relief
      (including injunction and specific performance) in any action
      instituted in any court of the United States or any state
      thereof having subject matter jurisdiction, as a remedy for any
      such breach or to prevent any breach of this Agreement.  Such
      remedies shall not be deemed to be the exclusive remedies for a
      breach or anticipatory breach of this Agreement, but shall be
      in addition to all other remedies available at law or equity to
      the parties hereto.  To the extent permitted by applicable law,
      the parties hereto irrevocably submit to the exclusive
      jurisdiction of the courts of the State of New York and the
      United States of America located in the State of New York for
      any suits, actions or proceedings arising out of or relating to
      this Agreement.

               12.  This Agreement, its Annexes and Exhibits contain
      the entire understandings of the parties with respect to the
      subject matter hereof, thereby superseding all prior agreements
      of the parties relating to the subject matter hereof (other
      than the Confidentiality Agreement entered into between the
      Purchaser and Viacom International Inc. dated July 1, 1993),
      and may not be amended except by a writing signed by the
      parties.  Except as otherwise provided herein, this Agreement
      is not assignable by any of the parties; provided that the
      Purchaser may assign its rights and obligations under this
      Agreement to a wholly owned subsidiary of the Purchaser, so
      long as the Purchaser shall remain liable for all financial and
      performance obligations of the Purchaser hereunder.  This
      Agreement shall be binding upon, and inure to the benefit of,
      the respective successors of the parties.  This Agreement may
      be executed in counterparts, each of which shall be deemed an
      original, but all of which together will constitute one and the
      same instrument.

               13.  Any notices and other communications required to
      be given pursuant to this Agreement shall be in writing and
      shall be given by delivery by hand, by mail (registered or
      certified mail, postage prepaid, return receipt requested) or
      by facsimile transmission or telex, as follows:

<PAGE>   13


      respect to the Asset Purchase Transaction, such period of time
      as is consistent with the terms of Annex II) following the

          (i)  "Measurement Period" shall mean the period commencing
          on the first day after the Termination Date and ending on
          the First Anniversary; provided that such period shall be
          extended by the number of days occurring after the

          (ii)  "Class B Trading Price" shall mean the highest Class B
          Trading Average that occurs within the Measurement Period
          for any consecutive 30 trading day period occurring within
          the Measurement Period.

          (iii)  "Class B Trading Average" shall mean with respect to
          any consecutive 30 trading day period the average of the
          closing prices for the Class B Common Stock for the trading
          days in such period on the American Stock Exchange, or if
          the American Stock Exchange is not the exchange on which
          the Class B Common Stock is then principally traded.

          (iv)  "Make-Whole Amount" shall mean the amount, if any,
          that is the sum of (A) 50% of the aggregate of (1) the
          number of Shares Beneficially Owned by the Purchaser (and
          not subject to contracts of sale) on the First Anniversary
          and (2) the Sold Shares multiplied by the difference between
          $55 and the Class B Trading Price, up to, but in no event
          exceeding for the purpose of such calculation, a difference
          of $4.40 and (B) 50% of the aggregate of (1) the number of
          Shares Beneficially Owned by the Purchaser (and not subject
          to contracts of sale) on the First Anniversary and (2) the
          Sold Shares multiplied by the difference between $55 and

          $19.80.

          (v) "Marketable Security" shall mean any debt or equity
          security, or a combination of debt and equity securities,

          cause such security to trade on a fully distributed basis
          after the date of its issuance at the value attributed to
          such security in satisfying the Make-Whole Amount as
          provided in paragraph 17(c) below.  If Smith Barney
          Shearson Inc. and Merrill Lynch & Co. are unable to agree
          on such terms within 10 Business Days after the First
          Anniversary, the Purchaser shall select one investment bank
          from a list of at least five investment banks of national
          standing supplied to the Purchaser by the Company, which
          investment bank shall, not later than 5 Business Days after
          its selection resolve, in its sole judgment, any such
          disagreements with respect to such terms.  The
          determination by such investment bank shall be final,
          binding and conclusive on the Company and the Purchaser,
          and the fees and expenses of such investment bank shall be
          borne equally by the Company and the Purchaser.

          (v)  "Sold Shares" shall mean up to the first 4,547,454
          Shares, and only up to the first 4,547,454 Shares, of any
          Shares sold by the Purchaser after the Termination Date and
          prior to the First Anniversary; provided that Sold Shares
          shall not include any of such Shares sold by the Purchaser
          for gross proceeds equal to or greater than $55 per Share.

          (vi)  "Asset Purchase Transaction" shall mean the
          transaction with the material terms described in Annex II.

               (c)  The Company shall be entitled to satisfy its
      obligation with respect to the Make-Whole Amount, at the option
      of the Company through written notice to the Purchaser no later
      than  5 Business Days following the First Anniversary, by any
      of the following means:

          (i)  Delivery to the Purchaser of cash in an amount equal
          to the Make-Whole Amount by wire transfer of immediately
          available funds to an account specified by the Purchaser;
          or

          (ii)  Delivery to the Purchaser of Marketable Securities
          with an aggregate value (determined as specified above)
          equal to the Make-Whole Amount; or
          (iii)  Delivery to the Purchaser of a combination of cash
          and Marketable Securities with an aggregate value equal to
          the Make-Whole Amount; or

          (iv)  Consummation of the Asset Purchase Transaction;



                                      14

      provided that in the event the Company has given notice to the
      Purchaser as provided above of its intent to satisfy all or a
      portion of the Make-Whole Amount with Marketable Securities and
      the Company determines, in its sole discretion, that the terms
      of the Marketable Securities are unacceptable to the Company,
      the Company shall be entitled to satisfy the Make-Whole Amount
      through any of the other means specified above in lieu of using
      Marketable Securities.

               18.  This Agreement shall be governed by and construed
      in accordance with the laws of the State of New York applicable
      to contracts executed in and to be performed entirely within
      that state.

                                        Very truly yours,

                                    ANNEX I

                              Registration Rights


               (a)  From time to time after the earlier of the
      termination of the Merger Agreement and September 30, 1994, the
      Purchaser shall have the right to make six requests of the
      Company in writing: with respect to the first such request to
      register under the 1933 Act at least $100 million in market
      value of the Shares beneficially owned by the Purchaser (the
      Shares subject to any such request hereunder being referred to
      as the "Subject Stock"), and with each subsequent such request
      being at least 6 months following such prior request which
      resulted in a registration statement with respect to the
      Subject Stock which was effective until the earlier of the
      completion of the offering of such Subject Stock or three
      months.  The Company shall use all reasonable efforts to cause
      the Subject Stock to be registered under the 1933 Act as soon
      as reasonably practicable after receipt of a request so as to
      permit promptly the sale thereof, and in connection therewith,
      the Company shall prepare and file, on such appropriate form as
      the Company in its discretion shall determine, a registration
      statement under the 1933 Act to effect such registration.  The
      Company shall use all reasonable efforts to list all Subject
      Stock covered by such registration statement on any national
      securities exchange on which the Class B Common Stock is then
      listed or, if such listing cannot be made, to list such Subject
      Stock on the National Association of Securities Dealers
      Automated Quotation System or National Market System.  The
      Purchaser hereby undertakes to provide all such information and
      materials and take all such action as may be required in order
      to permit the Company to comply with all applicable
      requirements of the Commission and to obtain any desired
      acceleration of the effective date of such registration
      statement.  Any registration statement filed at the Purchaser's
      request hereunder will not count as a requested registration
      (i) unless effectiveness is maintained until the earlier of
      completion of the offering and three months or (ii) if the
      Purchaser is required to reduce the number of Shares as to
      which registration was requested hereunder as a result of the
      inclusion in such registration of securities of a third party
      without the consent of the Purchaser.  Notwithstanding the
      foregoing, the Company (i) shall not be obligated to cause any
      special audit to be undertaken in connection with any such
      registration (provided that this provision shall not relieve
      the Company of its obligation to obtain any required consents
      with respect to financial statements in prior periods) and
      (ii) shall be entitled to postpone for a reasonable period of
      time (not to exceed 180 days) the filing of any registration
      statement otherwise






<PAGE>   18


      required to be prepared and filed by the Company if the Company
      is, at such time, either (A) conducting or in active
      preparation to conduct an underwritten public offering of
      equity securities (or securities convertible into equity
      securities) or is subject to a contractual obligation not to
      engage in a public offering and is advised in writing by its
      managing underwriter or underwriters (with a copy to the
      Purchaser) that such offering would in its or their opinion be
      adversely affected by the registration so requested or (B)
      subject to an existing contractual obligation to its
      underwriters not to engage in a public offering; provided,
      however, that the Company may not exercise such right to
      postpone the filing of a registration statement for more than
      180 days in any 365-day period.

               The Purchaser may use one or more of the registration
      requests to which it is entitled pursuant to the preceding
      paragraph to require the Company to register Shares on a
      registration statement also covering securities of the
      Purchaser convertible into or exchangeable for Shares and may
      assume primary responsibility for the preparation of such
      registration statement.  In such event, in which each of the
      Company and the Purchaser shall be registrants of securities
      registered, in addition to the indemnification provided herein,
      the Company shall be entitled to receive indemnifications from
      the Purchaser consistent with the indemnifications provided
      herein to be granted by the Company to the Purchaser and the
      Purchaser shall reimburse the Company for one half of any fees,
      expenses and disbursements referred to in the second sentence
      of paragraph (c) below for which the Company is otherwise
      responsible.

               At any time after the earlier of the termination of
      the Merger Agreement and September 30, 1994, if the Company
      proposes to file a registration statement under the 1933 Act
      with respect to an offering of shares of its equity securities
      (i) for its own account (other than a registration statement on
      Form S-4 or S-8 (or any substitute form that may be adopted by
      the Commission)) or (ii) for the account of any holders of its
      securities (including any pursuant to a demand registration),
      then the Company shall give written notice of such proposed
      filing to the Purchaser as soon as practicable (but in any
      event not less than 5 Business Days before the anticipated
      filing date), and such notice shall offer the Purchaser the
      opportunity to register such number of Shares as the Purchaser
      requests.  If the Purchaser wishes to register Shares, such
      registration shall be on the same terms and conditions as the
      registration of the Company's or such holders' shares of Class B
      Common Stock (a "Piggyback Registration").  Notwithstanding
      anything contained herein,





                                     2
<PAGE>   19



      if the lead underwriter of an offering involving a Piggyback
      Registration delivers a written opinion to the Company that the
      success of such offering would be materially and adversely
      affected by inclusion of all the securities requested to be
      included, then the number of securities to be registered by
      each party requesting registration rights shall be reduced in
      proportion to the number of securities originally requested to
      be registered by each of them.  Nothing contained herein shall
      require the Company to reduce the number of shares proposed to
      be issued by the Company.

               Other than as required by contractual obligations of
      the Company existing on the date of this Agreement, no
      securities may be registered on a registration statement
      requested by the Purchaser under this Agreement without the
      Purchaser's express written consent.  The Company agrees that
      following the date of this Agreement it shall not grant to any
      person any rights to compel inclusion of securities in any
      registration statement requested by the Purchaser under this
      Agreement without the Purchaser's express written consent.

               (b)  In connection with any offering of shares of
      Subject Stock registered pursuant to this Annex I, the Company
      (i) shall furnish to the Purchaser such number of copies of any
      prospectus (including any preliminary prospectus) as it may
      reasonably request in order to effect the offering and sale of
      the Subject Stock to be offered and sold, but only while the
      Company shall be required under the provisions hereof to cause
      the registration statement to remain current and (ii) take such
      action as shall be necessary to qualify the shares covered by
      such registration statement under such "blue sky" or other
      state securities laws for offer and sale as the Purchaser shall
      request; provided, however, that the Company shall not be
      obligated to qualify as a foreign corporation to do business
      under the laws of any jurisdiction in which it shall not then
      be qualified or to file any general consent to service of
      process in any jurisdiction in which such a consent has not
      been previously filed.  If applicable, the Company shall enter
      into an underwriting agreement with a managing underwriter or
      underwriters selected by the Purchaser (reasonably satisfactory
      to the Company) containing representations, warranties,
      indemnities and agreements then customarily included by an
      issuer in underwriting agreements with respect to secondary
      distributions; provided, however, that such underwriter or
      underwriters shall agree to use their best efforts to ensure
      that the offering results in a distribution of the Subject
      Stock sold in accordance with the terms of the agreement.  In
      connection with any offering of





                                       3

<PAGE>   20


      Subject Stock registered pursuant to this Annex I, the Company
      shall (x) furnish to the underwriter, at the Company's expense,
      unlegended certificates representing ownership of the Subject
      Stock being sold in such denominations as requested and (y)
      instruct any transfer agent and registrar of the Subject Stock
      to release any stop transfer orders with respect to such
      Subject Stock.  Upon any registration becoming effective
      pursuant to this Annex I, the Company shall use all reasonable
      efforts to keep such registration statement current for such
      period as shall be required for the disposition of all of said
      Subject Stock; provided, however, that such period need not
      exceed three months.

               (c)  The Purchaser shall pay all underwriting
      discounts and commissions related to shares of Subject Stock
      being sold by the Purchaser.  The Company shall pay all other
      fees and expenses in connection with any registration
      statement, including, without limitation, all registration and
      filing fees, all fees and expenses of complying with securities
      or "blue sky" laws, fees and disbursements of the Company's
      counsel, the counsel of the Purchaser, accountants (including
      the expenses of "cold comfort" letters required by or incident
      to such performance and compliance) and any fees and
      disbursements of underwriters customarily paid by issuers in
      secondary offerings.

               (d)  In the case of any offering registered pursuant
      to this Annex I, the Company agrees to indemnify and hold the
      Purchaser, each underwriter of Shares under such registration
      and each person who controls any of the foregoing within the
      meaning of Section 15 of the 1933 Act and the directors and
      officers of the Purchaser, harmless against any and all losses,
      claims, damages, liabilities or actions to which they or any of
      them may become subject under the 1933 Act or any other statute
      or common law or otherwise, and to reimburse them for any legal
      or other expenses reasonably incurred by them in connection
      with investigating any claims and defending any actions,
      insofar as any such losses, claims, damages, liabilities or
      actions shall arise out of or shall be based upon (i) any
      untrue statement or alleged untrue statement of a material fact
      contained in the registration statement relating to the sale of
      such Subject Stock, or the omission or alleged omission to
      state therein a material fact required to be stated therein or
      necessary to make the statements therein, in light of the
      circumstances under which they were made, not misleading or
      (ii) any untrue statement or alleged untrue statement of a
      material fact contained in any preliminary prospectus (as
      amended or supplemented if the Company shall have filed with
      the Commission any amendment





                                       4

<PAGE>   21


      thereof or supplement thereto), if used prior to the effective
      date of such registration statement, or contained in the
      prospectus (as amended or supplemented if the Company shall
      have filed with the Commission any amendment thereof or
      supplement thereto), or the omission or alleged omission to
      state therein a material fact necessary in order to make the
      statements therein, in light of the circumstances under which
      they were made, not misleading; provided, however, that the
      indemnification agreement contained in this paragraph (d) shall
      not apply to such losses, claims, damages, liabilities or
      actions which shall arise from the sale of Subject Stock by the
      Purchaser if such losses, claims, damages, liabilities or
      actions shall arise out of or shall be based upon any such
      untrue statement or alleged untrue statement, or any such
      omission or alleged omission, if such statement or omission
      shall have been (x) made in reliance upon and in conformity
      with information furnished in writing to the Company by the
      Purchaser or any such underwriter specifically for use in
      connection with the preparation of the registration statement
      or any preliminary prospectus or prospectus contained in the
      registration statement or any such amendment thereof or
      supplement thereto or (y) made in any preliminary prospectus,
      and the prospectus contained in the registration statement in
      the form filed by the Company with the Commission pursuant to
      Rule 424(b) under the 1933 Act shall have corrected such
      statement or omission and a copy of such prospectus shall not
      have been sent or given to such person at or prior to the
      confirmation of such sale to him.

               (e)  In the case of each offering registered pursuant
      to this Annex I, the Purchaser and each underwriter
      participating therein shall agree, in the same manner and to
      the same extent as set forth in paragraph (d) of this Annex I
      severally to indemnify and hold harmless the Company and each
      person, if any, who controls the Company within the meaning of
      Section 15 of the 1933 Act, and the directors and officers of
      the Company, and in the case of each such underwriter, the
      Purchaser, each person, if any, who controls the Purchaser
      within the meaning of Section 15 of the 1933 Act and the
      directors, officers and partners of the Purchaser, with respect
      to any statement in or omission from such registration
      statement or any preliminary prospectus (as amended or as
      supplemented, if amended or supplemented as aforesaid) or
      prospectus contained in such registration statement (as amended

               (f)  Each party indemnified under paragraph (d) or (e)
      of this Annex I shall, promptly after receipt of notice of the
      commencement of any action against such indemnified party in
      respect of which indemnity may be sought hereunder, notify the
      indemnifying party in writing of the commencement thereof.  The
      omission of any indemnified party to so notify an indemnifying
      party of any such action shall not relieve the indemnifying
      party from any liability in respect of such action which it may
      have to such indemnified party on account of the indemnity
      agreement contained in paragraph (d) or (e) of this Annex I,
      unless the indemnifying party was prejudiced by such omission,
      and in no event shall relieve the indemnifying party from any
      other liability which it may have to such indemnified party.
      In case any such action shall be brought against any
      indemnified party and it shall notify an indemnifying party of
      the commencement thereof, the indemnifying party shall be
      entitled to participate therein and, to the extent that it may
      desire, jointly with any other indemnifying party similarly
      notified, to assume the defense thereof, and after notice from
      the indemnifying party to such indemnified party of its
      election so to assume the defense thereof, the indemnifying
      party shall not be liable to such indemnified party under
      paragraph (d) or (e) of this Annex I for any legal or other
      expenses subsequently incurred by such indemnified party in
      connection with the defense thereof, other than reasonable
      costs of investigation.

               (g)  If the indemnification provided for under
      paragraph (d) or (e) shall for any reason be held by a court to
      be unavailable to an indemnified party under paragraph (d) or
      (e) hereof in respect of any loss, claim, damage or liability,
      or any action in respect thereof, then, in lieu of the amount
      paid or payable under paragraph (d) or (e) hereof, the
      indemnified party and the indemnifying party under paragraph
      (d) or (e) hereof shall contribute to the aggregate losses,
      claims, damages and liabilities (including legal or other
      expenses reasonably incurred in connection with investigating
      the same), (i) in such proportion as is appropriate to reflect
      the relative fault of the Company and the prospective seller of
      Securities covered by the registration statement which resulted
      in such loss, claim, damage or liability, or action in respect
      thereof, with respect to the statements or omissions which
      resulted in such loss, claim, damage or liability, or action in
      respect thereof, as well as any other relevant equitable
      considerations or (ii) if the allocation provided by clause

      (i) above is not permitted by applicable law, in such
      proportion as shall be appropriate to reflect the relative
      benefits received by the Company and such prospective seller
      from the offering of the securities covered by such
      registration statement.  No Person guilty of fraudulent
      misrepresentation (within the meaning of Section 11(f) of the
      1933 Act) shall be entitled to contribution from any Person who
      was not guilty of such fraudulent misrepresentation.  In
      addition, no Person shall be obligated to contribute hereunder
      any amounts in payment for any settlement of any action or
      claim effected without such Person's consent, which consent
      shall not be unreasonably withheld.

      Asset Purchase Transaction pursuant to paragraph 17, each of
      the Company and the Purchaser agrees to act in good faith and
      use all reasonable best efforts to take all steps necessary and
      advisable to effect the transaction consistent with the terms
      set forth in this Annex II as soon as practicable after such
      election is made.

      2.  Unless the parties otherwise agree and so long as such
      structure would be consistent with the intent of the
      transaction as expressed in this Annex II, the acquisition of
      the Parks Business by the Purchaser shall be effected through
      the acquisition of all of the capital stock of Patriot Parks
      Inc. and the Option of the Company to acquire a 50% equity
      interest in the Parks Business, if exercised, shall be effected

      Asset Purchase Transaction pursuant to paragraph 17 and the
      Purchaser does not Beneficially Own sufficient shares of Class B
      Common Stock to pay the full Parks Purchase Price with such
      shares, the Purchaser shall have the right, at its option,
      either (a) to pay in cash such amount of the Parks Purchase
      Price not paid in Class B Common Stock and thereby still
      purchase 100% of the Parks Business or (b) to purchase only
      such percentage of the equity of the Parks Business as equals
      the percentage of the Parks Purchase Price that the Purchaser
      pays with all of the shares of Class B Common Stock
      Beneficially Owned by the Purchaser.

          In the event that the Purchaser elects to purchase less
      than 100% of the Parks Business as provided immediately above,
      the following adjustments to the Asset Purchase Transaction
      shall be made:

          (A) The Company and the Purchaser shall enter into a
          stockholders' or other similar agreement containing such
          terms as are customary for joint ventures in which the
          equity is owned by two parties in the proportions in which
          the Company and the Purchaser would own the Parks Business;
          provided that in the event the Purchaser acquires less than
          a 50% equity interest in the Parks Business, the Company
          shall retain the right to elect a majority of the board of
          directors or other governing body of the Parks Business and
          to control the management of the Parks Business.

          (B) The Purchaser shall grant the Option to the Company
          only in the event that the Purchaser acquires an equity
          interest in the Parks Business of greater than 50% and the
          equity interest for which the Option may be exercised by
          the Company shall be equal only to such percentage as would
          result in the Purchaser, after exercise of the Option by
          the Company, owning a 50% equity interest in the Parks
          Business.  In such event, the Option Price shall be
          decreased in proportion to the percentage decrease from a
          50% equity interest to the percentage interest for which
          the Option shall be exercisable.

      Company, enforceable against the Company in accordance with its
      terms, except as enforcement thereof may be limited by
      bankruptcy, insolvency, reorganization, fraudulent conveyance
      or other similar laws affecting enforcement of creditors'
      rights generally and except as enforcement thereof is subject
      to general principles of equity (regardless of whether

      paid and nonassessable, have not been issued in violation of or
      subject to any preemptive rights and have the rights set forth

           - Market Capitalization of Combined
           Viacom/Blockbuster/Paramount
           Valued at $26 Billion -


           New York, New York, January 7, 1993 --  Viacom Inc. (ASE: VIA
           and VIAB) and Blockbuster Entertainment Corporation (NYSE: BV)
           today announced they have entered into a definitive merger
           agreement under which Blockbuster will merge into Viacom. 
           Under the terms of the agreement, which was unanimously
           approved by the Boards of Directors of both companies,
           Blockbuster shareholders will receive .08 of a share of Viacom
           Class A Common Stock, and .60615 of a share of Viacom Class B
           Common Stock, and one variable common right (VCR) for each
           share of Blockbuster.  The transaction is valued at $8.4
           billion, based on the closing market prices of Viacom stock on
           January 6, 1994.  The combined Viacom/Blockbuster company will
           be named Viacom-Blockbuster Inc.

           Viacom also announced an increase to $105 per share, or $6.5
           billion, for the 50.1% in cash consideration to be paid to
           shareholders of Paramount Communications Inc. (NYSE: PCI)
           under its revised tender offer.

           Viacom and Blockbuster together announced that, subject to the
           consummation of Viacom's tender offer for Paramount,
           Blockbuster has agreed to invest $1.25 billion in Viacom by
           purchasing approximately 23 million shares of Viacom Class B
           Common Stock at $55.00 per share.  The shares purchased by
           Blockbuster will reduce the number of shares previously
           offered to existing Paramount shareholders, placing shares
           that would otherwise have been distributed to public
           shareholders in the hands of Blockbuster.  The additional cash
           component of this transaction, provided by the Blockbuster
           investment, will provide Paramount shareholders with increased
           monetary consideration and added value, with virtually no
           dilution to shareholders.  In the context of the ultimate
           combination of Viacom, Blockbuster and Paramount, the
           resulting company will enjoy a significantly strengthened
           capital structure.  Upon the completion of the Paramount
           acquisition, the company will be renamed.

           "The combination of Viacom with Blockbuster and Paramount
           creates a uniquely diversified portfolio of global
           entertainment assets and operations with extraordinary
           capacity to exploit worldwide opportunities.  The potential
           for the exploitation and expansion of brand names and
           franchises will be dramatic," said Sumner M. Redstone,
           Chairman of the Board of Viacom. 

           "Blockbuster's established relationships with customers and
           large presence in the retail video and music markets provide
           Viacom with important access and distribution to consumers of
           entertainment products.

           "We look forward to welcoming Blockbuster and its employees to
           the Viacom family.  Blockbuster's headquarters will be
           maintained in Ft. Lauderdale.

           "From the very beginning, Viacom's strategic rationale for
           joining forces with Paramount was the creation of a new global
           entertainment powerhouse with an array of complementary,
           world-class assets in a wide variety of entertainment and
           communication businesses,"  Mr. Redstone stated. 

           H. Wayne Huizenga, Chairman of the Board of Blockbuster, said,
           "This transaction is an exciting development for our company
           and our shareholders, reflecting the vision we share with
           Viacom related to building a global integrated entertainment
           company.  Blockbuster's retail distribution systems and our
           programming and production business together with Viacom's
           entertainment franchises represent a formidable combination." 

           William C. Ferguson, Chairman of NYNEX Corporation, expressing
           strong support for today's announcement, said, "We initially
           joined forces with Viacom in our belief that Viacom presented
           numerous opportunities to leverage our existing businesses by
           pursuing joint opportunities.  We continue to believe that a
           combined Viacom/Blockbuster/ Paramount will bring value to
           NYNEX." 

           With the completion of the merger, Mr. Redstone will become
           Chairman of the Board of the combined company and will own 61%
           of the combined company's voting stock.  With the completion
           of the Blockbuster merger, Mr. Huizenga will

           become Vice Chairman of the combined company.  This new entity
           will have a mutually agreed upon Board of Directors consisting
           of six Directors designated by Viacom, three Directors
           designated by Blockbuster, including Mr. Huizenga and Steven
           R. Berrard, Blockbuster's Vice Chairman, two Directors
           designated by NYNEX Corporation, including William C.
           Ferguson, Chairman of NYNEX Corporation and a current Director
           of Viacom's board, and one independent Director.

           The Tender Offer for Paramount and Related Merger
           Viacom's tender offer has been extended to Friday, January 21,
           1994.  Under the terms of the Exemption Agreement between
           Viacom and Paramount and the Agreement and Plan of Merger
           between QVC Network Inc. and Paramount, Viacom said that QVC
           would also be required to extend its offer to expire no
           earlier than that date.  As permitted by the terms of the
           Exemption Agreement, Viacom's amended tender offer is for
           50.1% of the outstanding shares of the common stock of
           Paramount.  Viacom's offer contemplates the execution of a
           definitive merger agreement with Paramount providing for the
           conversion of each share of Paramount that is not acquired
           pursuant to the offer into the right to receive .93065 shares
           of Viacom Class B Common Stock and .30408 of a share of
           Viacom's convertible preferred stock.  Viacom said that as of
           the close of business on Thursday, January 6, 1994,
           approximately 2,305,900 shares of Paramount stock had been
           tendered and not withdrawn.

           Under the Exemption Agreement, Paramount is required to
           execute the definitive merger agreement if 50.1% of the
           outstanding shares of Paramount are validly tendered for
           Viacom's offer and not withdrawn by its expiration date. 
           Other terms of Viacom's offer, including the terms of the
           convertible preferred stock in the merger with Paramount, are
           substantially unchanged from Viacom's existing offer.

           The Blockbuster/Viacom Merger
           The merger of Blockbuster into Viacom, which is intended to be
           tax-free, is subject to customary conditions, including
           approval of shareholders of both companies.  However, the
           merger is not conditioned upon consummation of Viacom's tender
           offer or any other transaction involving Paramount.

           Viacom said that certain Blockbuster shareholders holding
           approximately 22.7% of the outstanding Blockbuster shares,
           including Mr. Huizenga and Mr. Berrard, had granted Viacom
           proxies to vote in favor of the proposed merger.  Viacom also
           said that certain Blockbuster shareholders granted Viacom
           options to purchase a portion of such shares amounting to 6.1%
           of Blockbuster's outstanding shares at a price of $30.125 per
           share.  Mr. Huizenga and Mr. Berrard were among the
           Blockbuster stockholders who provided Viacom with stock
           options and proxies with respect to their personal holdings of
           shares.

           The variable common rights (VCRs) to be issued in connection
           with this transaction convert into Viacom Class B shares under
           certain circumstances.  The number of Viacom Class B shares
           into which the VCRs will convert will 

           -more-

                                      6

           generally be based upon the highest 30 consecutive trading day
           average price for Viacom Class B Common Stock during the 90
           trading days prior to the conversion date, which occurs on the
           first anniversary of the completion of the Blockbuster merger. 
           In the event that such value is less than $48 per share and
           more than $40 per share, the VCRs will convert into the right
           to receive .05929 of a share of Viacom Class B Common Stock. 
           If such value is below $40 per share, such number of shares
           will increase ratably to the maximum of .13829 of a share of
           Viacom Class B Common Stock at a value of $36 per share or, if
           such value is above $48 per share, the number of shares into
           which the VCR will convert will decrease ratably to have no
           value at a price of $52 per share.  The upward adjustment in
           the value of the VCR in excess of .05929 of a share of Viacom
           Class B Common Stock will not be made in the event that,
           during any 30 trading day period following the completion of
           the merger and prior to the conversion date, the average
           closing price exceeds $40 per share. In the event that during
           any such period such average price exceeds $52 per share, the
           VCR will terminate.
