PREPARED FOR DELIVERY


SUMNER M. REDSTONE
JANUARY 10, 1994

It is not easy to know where to begin; so dramatic, indeed, awesome, 
are the events of recent hours.  Perhaps I should state at the outset 
that I have tremendous confidence in what we have done if for no 
other reason than that the decisions that were disclosed in recent 
days have had the unqualified support of the entire Viacom management 
team.  And I trust them!  And I respectfully submit that they warrant 
your trust in view of their proven track record of past success.

The merger of Blockbuster Entertainment into Viacom at a value of 
$8.4 billion creates a gigantic new presence in the global 
entertainment industry.  With more than 4,000 video stores, 
Blockbuster is the largest retailer of home video product in the 
world.  In addition, Blockbuster owns 511 music stores, including 20 
megastores, and will soon
 be the number one distributor of music 
products in the world.  Blockbuster at the same time is a leading 
producer and distributor of filmed entertainment, with more than 
20,000 hours of movies and television series through its investment in 
Spelling Entertainment and Republic Pictures.

And finally, Blockbuster brings to Viacom's enormous portfolio of 
assets its own unique mix of distribution and marketing skills, thus 
creating a new global force in the creation and distribution of 
entertainment.  Whatever the technological future, Blockbuster is a 
vibrant participant in the global media revolution.

As for Wayne Huizenga and Steve Berrard, they are legends among their 
peers.  They share with our management an obsessive commitment to 
excellence and an unparalleled record of managing diversified global 
assets and businesses.  What we at Viacom, and what Wayne and Steve 
and their colleagues at Blockbuster have accomplished, is a tribute 
to what talented management teams can bring to the assets of our 
companies.

Think about just a few aspects of this dynamic combination.  The 
enormous cash flows from Blockbuster and Viacom make more realizable 
the enormous global opportunities which each confronts, and indeed, 
moderate possible fluctuations in earnings from Paramount Studio.

Access to Blockbuster's 40 million person consumer database presents 
vast distribution advantages, particularly in new businesses where 
Blockbuster, for example, can double the sales of Viacom's new media 
interactive products.  In addition, Blockbuster's retail operations 
will be greatly enhanced by the addition of Viacom's programming 
franchises which include MTV, Nickelodeon and Showtime.  In fact, 
Blockbuster's retail operations can provide Viacom the basis for
quickly fulfilling its goal to enter the worldwide retailing 
business.

                                       -2-


Together, Blockbuster and Viacom will be the largest customer of 
Hollywood and record companies, with obvious advantages in price, 
promotion and otherwise.  And, with Viacom's film and television 
library of 8,500 titles, Blockbuster and Viacom together will control 
nearly 30,000 hours of movies and television series.

In short, Viacom's and Blockbuster's tremendous record of global 
expansion and brand development are joined in this new exciting 
global enterprise.

As for Paramount, our enthusiasm for that combination remains 
unabated.  From the beginning, Viacom's strategic rationale for 
acquiring Paramount was the creation of a global entertainment 
powerhouse with a premiere array of complementary worldwide assets 
across a wide variety of entertainment and communications businesses.  
That objective is enhanced with the Blockbuster Entertainment merger.  
With the addition of Paramount's extensive library of nearly 7,000 
titles, the combined companies will own nearly 40,000 programming 
titles.  Blockbuster's vast customer database will provide an 
invaluable resource -- indeed, a unique resource -- for tapping 
consumer preferences about movies, television, video games and music.  
In short, a Viacom/Blockbuster/Paramount combination will be a 
powerful force in virtually every aspect of the media and 
entertainment world -- from production in all media to distribution 
in all media.

In the course of achieving the monumental objective of bringing these 
three companies together, I personally -- as have others -- suffered 
much personal pain, but realizing this dream makes it worth it.  All 
of you know, as so I, that we pay a price for achieving what is 
worthwhile.

And now for our Paramount bid.  Our bid is not coercive.  Our bid is 
not cynical.  Our bid is rational.  The cash component of our bid is 
clearly superior to that of QVC.  Throughout the past several weeks, 
QVC has emphasized the cash component of its bid, which is now 
inferior to ours.  We added to the cash component of our bid without 
compromising our balance sheet, with less leverage and without 
dilution of our share value.

Cash is king!  And the reason for this, as you all understand, is 
that cash is the only thing you can measure with certainty.  Last 
Friday, for example, at the very end of the day, our shares fell 
while QVC's rose.  This happened for no other reason than the word 
got out that we were going to make a new bid.  On the other hand, one 
day not long ago, in about three minutes our shares rose in value by 
about $5.00 a share before trading stopped.  The reason was that it 
appeared that QVC had a final merger agreement with Paramount.  In 
short, these shares have been deal-driven when, in fact, they should 
be value-driven.  Blockbuster recognized the emphasis on value when 
it paid $55.00 per share for its $1.25 billion investment in Viacom.  
What Paramount stockholders should be asking themselves is where, six 
months from now, QVC/Paramount stock would trade as opposed to where 
Viacom/Paramount, indeed Viacom/Paramount/Blockbuster stock would 
trade.

Long ago, many of you heard me say that I would not do a mega-deal 
for glory or because I thought that bigger was necessarily better.  I 
stated that I would only do a mega-deal if it was rational and 
economically sound.  That was my commitment to Viacom, to myself and 
to my fellow shareholders.  That commitment is cast in stone.

And now, just a word or two about that little company called Viacom.  
You saw us take Viacom in just a few short years from an LBO to one 
of the fastest growing global media companies in the world.  In the 
United States, in Europe, from Hong Kong to Moscow, from Berlin to 
Beirut, in Europe itself, where MTV distribution now exceeds MTV 
distribution in the United States, from South America and soon to 
South Africa, and across all our businesses from our new media 
business to Showtime to the migration of all our basic services 
beyond the limits of the United States, including MTV and soon 
Nickelodeon in Asia, things are jumping at Viacom today like never 
before.

And it will not stop!

     Except as otherwise set forth in this Second Supplement, the terms and
conditions previously set forth in the Offer to Purchase and the First
Supplement remain applicable in all respects to the Offer, and this Second
Supplement should be read in conjunction with the Offer to Purchase and the
First Supplement. Unless the context requires otherwise, terms not defined
herein have the meanings ascribed to them in the Offer to Purchase and the First
Supplement.
 

     THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, 61,607,894 SHARES, OR
SUCH GREATER NUMBER OF SHARES AS EQUALS 50.1% OF THE SHARES OUTSTANDING PLUS THE
SHARES ISSUABLE UPON THE EXERCISE OF THE THEN EXERCISABLE STOCK OPTIONS AS OF
THE EXPIRATION DATE, BEING VALIDLY TENDERED AND NOT WITHDRAWN PRIOR TO THE
EXPIRATION DATE (THE "MINIMUM CONDITION"). THE OFFER IS ALSO SUBJECT TO OTHER
TERMS AND CONDITIONS. SEE SECTION 5 OF THIS SECOND SUPPLEMENT, WHICH SETS
FORTH IN FULL THE CONDITIONS OF THE OFFER.

 

     In the event the Offer is consummated, Purchaser intends to effectuate a
second-step merger pursuant to which each Share that is issued and outstanding
prior to the Effective Time (as defined below) of such merger would be converted
into the right to receive (i) .93065 shares of Class B Common Stock, par value
$.01 per share, of Purchaser (the "Viacom Class B Common Stock") and (ii)
.30408 shares of a new series of cumulative convertible exchangeable preferred
stock, par value $.01 per share, of Purchaser (the "Viacom Merger Preferred
Stock") (collectively, the "Merger Consideration"). The Viacom Merger
Preferred Stock will bear dividends at a rate of 5% per annum, will be
convertible into Viacom Class B Common Stock at a conversion price of $70, 
will have a liquidation preference of $50 per share, will be redeemable by 
Purchaser at declining redemption premiums after the fifth anniversary of the 
Effective Time, and will be exchangeable at the option of Purchaser into 
Purchaser's 5% Convertible Subordinated Debentures after the third anniversary 
of the Effective Time.

 

     The Offer was initially made pursuant to an Amended and Restated Agreement
and Plan of Merger dated as of October 24, 1993 (the "October 24 Merger
Agreement"), as amended on November 6, 1993 (as so amended, the "Merger
Agreement"), between Purchaser and the Company. The October 24 Merger Agreement
amended and restated in its entirety an Agreement and Plan of Merger dated as of
September 12, 1993 between Purchaser and the Company. On December 22, 1993, the
Company terminated the Merger Agreement pursuant to a notice of termination.
Also on December 22, 1993, the Company and Purchaser entered into an Exemption
Agreement (the "Exemption Agreement") which provides, among other things, that
in the event that (1) the Company's Board of Directors intends to recommend to
the stockholders of the Company the acceptance of the Offer or (2) such number
of Shares that would satisfy the Minimum Condition shall have been validly
tendered and not withdrawn in the Offer at the Expiration Date and, as of such
Expiration Date, Purchaser has waived all conditions to the Offer (other than
the Rights Condition, the Supermajority Condition, the Section 203 Condition and
the Injunction Condition (each as defined in Section 5 of this Second
Supplement) and the Minimum Condition) then Purchaser shall promptly execute and
deliver to the Company the Form of Merger Agreement (the "Form of Merger
Agreement") annexed to the Exemption Agreement (with representations and
warranties dated as of the date of execution of such Form of Merger Agreement,
unless otherwise specified therein, and with such other changes as may be
necessary to reflect the terms of the Offer as it then exists, changes in the
consideration offered under the executed Form of Merger Agreement and changes
related thereto) and the Company will execute such Form of Merger Agreement
(with representations and warranties dated as of the date of execution


<PAGE>

of such Form of Merger Agreement, unless otherwise specified therein) within one
business day of receipt thereof.

     Under the terms of the Exemption Agreement, the Company has agreed that
upon delivery by Purchaser of a Completion Certificate (as defined below), it
will take all necessary action to amend the Rights Agreement to make it
inapplicable, except under certain circumstances, to the Offer and to take all
appropriate action so that the restrictions on business combinations in (i)
Article XI of the Company's Certificate of Incorporation and (ii) Section 203 of
the General Corporation Law of the State of Delaware ("Delaware Law") will not
apply to the consummation of the Offer. See Section 4 of this Second Supplement.

     The Form of Merger Agreement provides, among other things, that as soon as
practicable after the purchase of Shares pursuant to the Offer, the approval of
the Merger (as defined below) by the stockholders of Purchaser and the Company
and the satisfaction of the other conditions set forth in the Form of Merger
Agreement and described in this Offer to Purchase, the Company will be merged
with and into Purchaser (the "Merger") in accordance with the relevant
provisions of Delaware Law. In such event, following consummation of the
Merger, Purchaser will continue as the surviving corporation (the "Surviving
Corporation").

     Alternatively, if Shearman & Sterling, counsel to Purchaser, is unable to
deliver an opinion, in form and substance reasonably satisfactory to Purchaser,
that the Merger will qualify as a reorganization under section 368(a) of the
Internal Revenue Code of 1986, as amended, Purchaser may elect to cause the
Merger to be effected by causing a wholly owned subsidiary of Purchaser to merge
with and into the Company in accordance with Delaware Law. In such event, the
separate corporate existence of such subsidiary will cease, and the Company will
continue as the Surviving Corporation as a wholly owned subsidiary of Purchaser.
 
     Based on the terms of the Offer and the proposed terms of the Form of
Merger Agreement, it is anticipated that Shearman & Sterling will be unable to
deliver the opinion referred to in the immediately preceding paragraph, and thus
that Purchaser will elect to change the form of the Merger. As a result,
exchanges of Shares pursuant to the Offer or the Merger will be taxable
transactions to stockholders of the Company for Federal income tax purposes. See
Section 6 of this Second Supplement.

     Purchaser intends to provide in the executed Form of Merger Agreement that
at the effective time of the Merger (the "Effective Time"), in the event the
Offer has already been consummated, each Share that is issued and outstanding
immediately prior to the Effective Time (other than Shares held in the treasury
of the Company or owned by Purchaser or any direct or indirect wholly owned
subsidiary of Purchaser or of the Company) will be converted into the right to
receive the Merger Consideration.

     On January 7, 1994, Purchaser and Blockbuster Entertainment Corporation, a
Delaware corporation ("Blockbuster"), entered into an Agreement and Plan of
Merger (the "Blockbuster Merger Agreement") pursuant to which Blockbuster will
be merged with and into Purchaser (the "Blockbuster Merger"), with Purchaser as
the surviving corporation (the "Blockbuster Merger Surviving Corporation"). See
Sections 9 and 10 of this Second Supplement for certain information regarding
Blockbuster and a description of the Blockbuster Merger Agreement.

     In connection with the Blockbuster Merger, an aggregate of approximately
19.8 million shares of Viacom Class A Common Stock and 149.9 million shares of
Viacom Class B Common Stock and VCRs (as defined below) representing a maximum 
of approximately 34.2 million additional shares of Viacom Class B Common
Stock would be issuable in the Blockbuster Merger. In addition, an aggregate
of approximately 1.5 million additional shares of Viacom Class A Common Stock
and 11.3 million additional shares of Viacom Class B Common Stock, and VCRs
representing a maximum of approximately 2.6 million additional shares of
Viacom Class B Common Stock would be issuable in connection with the possible
exercise of stock options and Warrants.

     Procedures for tendering Shares are set forth in Section 3 of the Offer to
Purchase. Tendering stockholders may use either the original (Yellow) Letter of
Transmittal and the original (Blue) Notice of Guaranteed Delivery previously
circulated with the Offer to Purchase, the (Green) Letter of Transmittal and the
(Pink) Notice of Guaranteed Delivery circulated with the First Supplement or 
the revised (Orange) Letter of Transmittal and the revised (Yellow) Notice of
Guaranteed Delivery circulated with this Second Supplement. While the original
Letter of Transmittal circulated with the Offer to Purchase refers to the
Offer to Purchase, and the Letter of Transmittal circulated with the First
Supplement refers to the Offer to Purchase and the First Supplement,
stockholders using such documents to tender Shares will nevertheless receive
$105 per Share for each Share validly tendered and not withdrawn and accepted
for payment pursuant to the Offer, subject to the conditions of the Offer.
Stockholders who have previously validly tendered
                                       2


<PAGE>

and not withdrawn Shares pursuant to the Offer are not required to take any
further action in order to receive, subject to the conditions of the Offer, the
increased tender price of $105 per Share, if the Shares are accepted for payment
and paid for by Purchaser pursuant to the Offer, except as may be required by
the guaranteed delivery procedure if such procedure was utilized. See Section 1
of this Second Supplement.

     THE OFFER TO PURCHASE, THE FIRST SUPPLEMENT AND THIS SECOND SUPPLEMENT
CONTAIN IMPORTANT INFORMATION WHICH SHOULD BE READ BEFORE ANY DECISION IS MADE
WITH RESPECT TO THE OFFER.
 
     1. AMENDED TERMS OF THE OFFER; EXPIRATION DATE. The Offer is being made for
61,607,894 Shares, or such greater number of Shares as equals 50.1% of the
Shares outstanding plus the Shares issuable upon the exercise of the then
exercisable stock options as of the Expiration Date. The price per Share to be
paid pursuant to the Offer has been increased from $85.00 per Share to $105 per
Share, net to the seller in cash. All stockholders whose Shares are validly
tendered and not withdrawn and accepted for payment pursuant to the Offer
(including Shares tendered prior to the date of this Second Supplement) will
receive the increased price.

     This Second Supplement, the revised (Orange) Letter of Transmittal and
other relevant materials will be mailed to record holders of Shares whose names
appear on the Company's stockholder list and will be furnished, for subsequent
transmittal to beneficial owners of Shares, to brokers, dealers, commercial
banks, trust companies and similar persons whose names, or the names of whose
nominees, appear on the stockholder list or, if applicable, who are listed as
participants in a clearing agency's security position listing.
 
     2. PRICE RANGE OF SHARES; DIVIDENDS. The discussion set forth in Section 6
of the Offer to Purchase and Section 2 of the First Supplement is hereby amended
and supplemented as follows:

     According to published financial sources, the Company has paid no cash
dividends on the Shares since the date of the Offer to Purchase.

     The high and low sales prices per Share on the New York Stock Exchange (the
"NYSE") as reported by the Dow Jones News Service for the fiscal quarter ended
October 31, 1993 were $81.00 and $51.00, respectively, and the high and low
sales prices per Share for the current fiscal quarter through January 6, 1994,
were $83 1/2 and $73 1/2, respectively. On January 6, 1994, the last full
trading day prior to the announcement of the increase in the price per Share to
be paid pursuant to the Offer, the closing price per Share as reported on the
NYSE was $78 1/2.

     STOCKHOLDERS ARE URGED TO OBTAIN A CURRENT MARKET QUOTATION FOR THE SHARES.
 
     3. FINANCING OF THE OFFER AND THE MERGER. The discussion set forth in
Section 9 of the Offer to Purchase and Section 3 of the First Supplement is
hereby amended and supplemented as follows:

     The total amount of funds required by Purchaser to consummate the Offer and
the Merger and to pay related fees and expenses is estimated to be approximately
$6.6 billion.

     Purchaser has obtained $600 million of such funds from the issuance and
sale of 24 million shares of Purchaser's Series A Cumulative Convertible
Preferred Stock to Blockbuster. Purchaser has obtained $1.2 billion of such
funds from the issuance and sale of 24 million shares of Purchaser's Series B
Cumulative Convertible Preferred Stock to NYNEX Corporation ("NYNEX"). Purchaser
will obtain the remaining $4.8 billion of such funds from the bank credit
facility described below, from the sale of Viacom Class B Common Stock to
Blockbuster pursuant to the Blockbuster Subscription Agreement described below
or from other sources.

     Bank Financing. On November 19, 1993, Purchaser entered into a definitive
credit agreement (as amended by an amendment dated January 4, 1994, the "Credit
Agreement") pursuant to which the banks parties thereto (the "Lenders") agreed
to lend to Purchaser up to $4.8 billion (the "Bank Facility"), comprised of a
$3.7 billion senior unsecured 364-day revolving credit facility (the "Revolving
Facility") and a $1.1 billion term loan (the "Term Loan Facility"). The Lenders
made the following commitments to the Revolving Facility: Morgan Guaranty Trust
Company of New York, Citibank, N.A. and The Bank of New York (the "Managing
Agents"), $318,965,517.24 each; Bank of America National Trust and Savings
Association, The First National Bank of Boston, Bank of Montreal, The Chase
Manhattan Bank (National Association), Canadian Imperial Bank of Commerce and
Societe Generale, $159,482,758.62 each; Credit Suisse, The Fuji Bank, Limited,
Credit Lyonnais, Cayman Island Branch, The First National Bank of Chicago, The
Industrial Bank of Japan, Ltd., Mellon Bank, N.A., The Mitsubishi Bank, Ltd.,
Royal Bank of Canada, Shawmut Bank Connecticut, N.A., Nippon
                                       3


<PAGE>

Credit Bank, Ltd., Los Angeles Agency, Sanwa Bank, Ltd. and Banque Paribas,
$127,586,206.90 each; and National Westminster Bank USA, National Westminster
Bank, PLC, Union Bank and The Bank of Tokyo Trust Company, $63,793,103.45 each.
Purchaser has terminated the Term Loan Facility in connection with obtaining the
funds from NYNEX referred to above.


     The Credit Agreement provides that up to the full amount of the Revolving
Facility may be borrowed, prepaid and reborrowed until 364 days after execution
and delivery of the Credit Agreement, at which time all amounts outstanding
under the Revolving Facility will become due and payable.


     Purchaser may elect to borrow under the Bank Facility at either the Base
Rate or the Eurodollar Rate (each as defined below). The "Base Rate" would be
the higher of (i) Citibank, N.A.'s Base Rate and (ii) the Federal Funds Rate
plus 1/2 of 1%. The "Eurodollar Rate" would be the London Interbank Offered Rate
plus (i) 0.6875%, until Purchaser's long-term debt is rated by Standard & Poor's
Corporation ("S&P") or Moody's Investors Service, Inc. ("Moody's"), and (ii)
thereafter, a variable rate ranging from 0.2500% to 0.8750% dependent on the
senior unsecured long-term debt ratings assigned to Purchaser. The Eurodollar
Rate would be available for one, two, three or six month borrowings. Interest on
Base Rate borrowings would be payable quarterly in arrears. Interest on
Eurodollar Rate borrowings would be payable in arrears (i) at the end of each
applicable interest period and (ii) in the case of a period longer than three
months, every three months.


     The Credit Agreement provides that Purchaser will pay each of the Lenders a
facility fee on such Lender's commitment in effect, from time to time (whether
or not utilized), from the execution and delivery of the Credit Agreement until
the termination of the Bank Facility, payable quarterly in arrears, at the rate
of (i) 0.3125% per annum, until Purchaser's senior unsecured long-term debt is
rated by S&P or Moody's, and (ii) thereafter, a variable rate ranging from
0.1000% to 0.3750% dependent on the senior unsecured long-term debt ratings
assigned to Purchaser. The Credit Agreement provides that the obligations of
each Lender to make advances under the Bank Facility will be subject to the
satisfaction or waiver of the following conditions: (i) Purchaser shall have
acquired at least 50.1% of the Shares outstanding plus the Shares issuable upon
the exercise of the then exercisable stock options, as of the expiration of the
Offer; (ii) all regulatory approvals required for the consummation of the Offer
and the Merger shall have been obtained and be in effect (and all applicable
waiting periods relating thereto shall have expired), except (a) approval of the
Proxy Statement by the Securities and Exchange Commission and (b) approval of
the Long Form Application by the FCC; provided that no approval obtained to
consummate the Offer or that would be required from the FCC to consummate the
Merger would require the divestiture of the Shares, and provided that Purchaser
covenants to refrain from taking any action under the Voting Trust Agreement
that would result in the sale of the Shares and to take all actions with respect
to transfer applications before the FCC to assure that the Shares will not be
required to be sold by order of the FCC; (iii) certain representations and
warranties shall be true in all material respects as of the time of borrowing;
(iv) Purchaser shall be in compliance with the financial covenants contained in
the Credit Agreement; (v) there having been no material adverse change since
September 30, 1993 (except as publicly disclosed prior to October 26, 1993 or as
disclosed as of November 19, 1993 in the Merger Agreement) in the business,
financial condition, operations or properties of Purchaser, the Company and
their respective subsidiaries considered on a pro forma basis taken as a whole;
(vi) no default or event of default under the Credit Agreement shall have
occurred and be continuing at the time of borrowing; (vii) no material
litigation shall be pending or threatened against Purchaser or a subsidiary in
which there is a reasonable probability of adverse decision which could have a
material adverse effect; (viii) the Merger Agreement, as amended, shall be in
full force and effect; and (ix) the Lenders shall have received certificates,
opinions of counsel and other documents satisfactory to the Lenders.


     Under the Credit Agreement, Purchaser has agreed to pay to the Lenders fees
customary for commitments of the type described herein as well as certain
out-of-pocket expenses of the Managing Agents arising in connection with the
preparation, execution and delivery of the Credit Agreement and the syndication
of the Bank Facility. In addition, Purchaser has agreed to indemnify each of the
Lenders and certain related persons against certain liabilities.

 
     The foregoing is a summary of the Credit Agreement and is qualified in its
entirety by reference to the Credit Agreement, a copy of which is filed as an
Exhibit to the Schedule 14D-1.
 
                                       4

<PAGE>
     Purchaser anticipates that the indebtedness incurred through borrowings
under the Bank Facility will be repaid from a variety of sources, which may
include, but may not be limited to, funds generated internally by Purchaser and
its subsidiaries (including, following the Merger, funds generated by the
Company), bank refinancing, and the public or private sale of debt or equity
securities. No decision has been made concerning the method Purchaser will
employ to repay such indebtedness. Such decision will be made based on
Purchaser's review from time to time of the advisability of particular actions,
as well as on prevailing interest rates and financial and other economic
conditions and such other factors as Purchaser may deem appropriate.
 

     Equity Financing. On January 7, 1994, Purchaser and Blockbuster entered
into a subscription agreement (the "Blockbuster Subscription Agreement")
pursuant to which Blockbuster has agreed to subscribe for and purchase from
Purchaser, and Purchaser has agreed to issue and sell to Blockbuster,
22,727,273 shares of Viacom Class B Common Stock for an aggregate purchase price
of approximately $1,250,000,000, representing a purchase price of $55 per share.


     The obligation of each of Purchaser and Blockbuster to consummate such
purchase and sale is subject to (i) the other party having performed in all
material respects all of its obligations under the Blockbuster Subscription
Agreement and the accuracy in all material respects of the representations and
warranties made by such other party in the Blockbuster Subscription Agreement,
(ii) there being no judgment, injunction, order or decree which materially
restricts, prevents or prohibits the consummation of such purchase and sale,
(iii) the receipt of satisfactory legal opinions and (iv) Purchaser having
accepted for payment 50.1% of the Shares pursuant to the Offer.


     Purchaser has agreed that it will 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 Offer and the Merger, without the prior
consent of Blockbuster, which consent shall not be unreasonably withheld.


     Pursuant to the Blockbuster Subscription Agreement, Purchaser has granted
Blockbuster customary registration rights with respect to the shares of Viacom
Class B Common Stock purchased thereunder.


     The Blockbuster Subscription Agreement requires each party to indemnify the
other and its affiliates, officers, directors, employees, agents, successors and
assigns for liabilities, losses, damages, claims, costs and expenses, interest,
awards, judgments and penalties arising out of or resulting from a breach of any
of such party's representations, warranties or covenants contained therein.


     In the event the Blockbuster Merger Agreement is terminated (other than by
Purchaser as a result of a breach of a representation, warranty, covenant or
agreement of Blockbuster contained therein), the Blockbuster Subscription
Agreement grants to Blockbuster certain rights in the event that Viacom Class B
Common Stock trades at levels below $55 per share during the one year period
after such termination. In the event that the highest average trading price of
the Viacom Class B Common Stock during any consecutive 30 trading day period
prior to the first anniversary of such termination of the Blockbuster Merger
Agreement is below $55 per share, Blockbuster shall be entitled to satisfaction
by Purchaser of a make-whole amount. Such make-whole amount may not exceed a
maximum amount equal to the sum of one half the number of shares of Viacom Class
B Common Stock purchased by Blockbuster under the Blockbuster Subscription
Agreement multiplied by the amount of such highest average trading price
deficiency not in excess of $4.40 and one half the number of such shares of
Viacom Class B Common Stock multiplied by the amount of such highest average
trading price deficiency not in excess of $19.80, resulting in a maximum
potential make-whole amount of $275 million.

 
     Under the Blockbuster Subscription Agreement, Purchaser is entitled to
satisfy its obligation with respect to any such make-whole amount, at
Purchaser's option, either through the payment to
                                       5

<PAGE>

Blockbuster of cash or marketable equity or debt securities of Purchaser, or a
combination thereof, with an aggregate value equal to the make-whole amount or,
if the Merger has occurred, through the sale to Blockbuster of the theme parks
currently owned and operated by the Company (the "Parks Business").

 

     In the event that Purchaser were to elect to fulfill its obligation to
satisfy the make-whole amount through the sale of the Parks Business to
Blockbuster, the purchase price would be $750 million, subject to adjustment for
certain capital expenditures, payable through delivery to Purchaser of shares of
Viacom Class B Common Stock valued at $55 per share. If the Parks Business were
so purchased by Blockbuster, the Blockbuster Subscription Agreement provides
that Blockbuster would grant an option to Purchaser, exercisable for a period of
two years after the date of grant, to purchase a 50% equity interest in the
Parks Business at a purchase price of $375 million, subject to adjustment for
certain capital expenditures, payable in cash.

 

     The foregoing is a summary of the Blockbuster Subscription Agreement and is
qualified in its entirety by reference to the Blockbuster Subscription
Agreement, a copy of which is filed as an Exhibit to the Schedule 14D-1.

 
     4. BACKGROUND OF THE OFFER SINCE NOVEMBER 8, 1993; CONTACTS WITH THE
COMPANY; THE EXEMPTION AGREEMENT AND THE FORM OF MERGER AGREEMENT. The
discussion set forth in Section 10 of the Offer to Purchase and Section 4 of the
First Supplement is hereby amended and supplemented as follows:
 
     On November 24, 1993, the Delaware Court of Chancery issued a Preliminary
Injunction Order (the "Preliminary Injunction Order") in connection with the
Delaware litigation commenced by QVC Network, Inc. ("QVC") and certain
stockholders of the Company pursuant to which:
 

          (1) The Company was preliminarily enjoined absent further order of the
     Chancery Court from amending the Rights Agreement or taking any other
     action under the Rights Agreement to, among other things, facilitate the
     Offer or second-step Merger.

 
          (2) The Company and Purchaser were enjoined from (i) taking any action
     to exercise, cash out, enforce, effectuate or consummate any term or
     provision of the Stock Option Agreement or (ii) causing the Company or its
     subsidiaries or affiliates to pay money, transfer assets or issue
     securities of the Company to Purchaser or any of its affiliates or
     subsidiaries other than in the ordinary course of business or pursuant to
     the termination fee provided for in Section 8.05 of the Merger Agreement.
 
          (3) QVC's motion to enjoin payment of the termination fee provided for
     in Section 8.05 of the Merger Agreement was denied.
 
     The grant of the injunction was appealed by Purchaser and the Company to
the Supreme Court of the State of Delaware.
 
     On December 9, 1993, the Delaware Supreme Court issued an order (the
"Order") pursuant to which the Court, among other things, (1) affirmed the
Preliminary Injunction Order and (2) remanded the proceeding to the Delaware
Chancery Court for proceedings consistent with the Order.
 

     On December 20, 1993, in accordance with bidding procedures established by
the Paramount Board, Purchaser delivered to the Company's financial advisor its
revised proposal for the acquisition of the Company.

 

     On December 22, 1993, Purchaser and the Company entered into the Exemption
Agreement, with the Form of Merger Agreement attached thereto, setting forth
certain procedures to govern the Offer and which is described below. Also on
December 22, 1993, the Company terminated the Merger Agreement and entered into
an Agreement and Plan of Merger with QVC (the "QVC Merger
                                       6


<PAGE>
Agreement"). The QVC Merger Agreement contains procedures applicable to the QVC
Offer which are substantially identical to the terms of the Exemption Agreement
applicable to the Offer. In addition, the QVC Merger Agreement contains as an
Exhibit thereto a form of exemption agreement containing terms substantially
identical to the Exemption Agreement, which QVC has agreed to enter into in
the event that the QVC Merger Agreement is terminated.
 
     The Exemption Agreement. The following is a summary of certain provisions
of the Exemption Agreement, a copy of which (together with the Form of Merger
Agreement attached as Exhibit A thereto) was previously filed as an Exhibit to
the Schedule 14D-1 and is incorporated herein by reference. The following
summary is qualified in its entirety by reference to the Exemption Agreement
filed as an Exhibit to the Schedule 14D-1.

     Agreements of the Company. Under the terms of the Exemption Agreement, the
Company has agreed that, upon delivery by Purchaser of the Completion
Certificate (as defined below), it shall take all necessary action to amend the
Rights Agreement so that the consummation of the Offer on the terms permitted
under the Exemption Agreement and as contemplated by the Form of Merger
Agreement will not cause (i) the Rights issued pursuant to the Rights Agreement
to become exercisable under the Rights Agreement, (ii) Purchaser or any
subsidiary of Purchaser to be deemed an "Acquiring Person" (as defined in the
Rights Agreement), or (iii) the "Stock Acquisition Date" (as defined in the
Rights Agreement) to occur upon such consummation; provided, however, that the
Company will not be required to make such amendments to the Rights Agreement if
(A) Purchaser has not performed or complied in all material respects with all
agreements and covenants required by the Exemption Agreement to be performed or
complied with by it on or prior to the consummation of the Offer or (B) the
Company obtains and there is in force from the Delaware Court of Chancery an
order declaring that the making of such amendments to the Rights Agreement would
be contrary to the fiduciary duties of the Paramount Board. Notwithstanding the
foregoing, in no event will the Company's Board of Directors make an amendment
of the Rights Agreement in favor of QVC or any other person without making such
amendments in favor of Purchaser; provided that the Company will not be
obligated to make such amendments for Purchaser if Purchaser has become
obligated to terminate the Offer pursuant to the provisions of the Exemption
Agreement as set forth in "Termination of the Offer" below.

     The Company has agreed under the terms of the Exemption Agreement that it
will take all appropriate actions so that the restrictions on business
combinations contained in (i) Article XI of the Company's Certificate of
Incorporation and (ii) Section 203 of Delaware Law will not apply to the
consummation of the Offer; provided, however, that such action will not be
effective if the Company is not required to amend the Rights Agreement as
contemplated in the immediately preceding paragraph.
 
     Agreements Regarding Terms of the Offer. Purchaser has also agreed under
the Exemption Agreement (i) that so long as QVC is bound by substantially
identical restrictions made for the benefit of the Company, not to amend the
Offer in order to (A) increase by less than $60 million the aggregate cash
consideration to be paid pursuant to the Offer or (B) increase the number of
Shares for which tenders are sought by less than 2% of the outstanding Shares;
(ii) not to extend the Expiration Date, except for extensions pursuant to
certain provisions of the Exemption Agreement, and except (x) as a result of
failure to satisfy a condition at the Expiration Date or (y) for any such
extension required by federal securities law; (iii) that no extension of the
Expiration Date permitted under the Exemption Agreement shall be for a period of
less than three business days; and (iv) that the Expiration Date shall not be
extended for any reason beyond 12:00 midnight on February 14, 1994, subject to
certain provisions of the Exemption Agreement or as required by federal
securities law to the extent that the extension arises due to an event other
than a change in the terms of the Offer (the "Final Expiration Date"). Purchaser
has agreed that it will not increase the per share consideration offered in the
Offer or otherwise amend the Offer primarily to extend the expiration date of
the QVC Offer.
 
                                       7

<PAGE>
     Purchaser has agreed that, without the prior written consent of the
Company, no change in the terms of the Offer shall be made which (i) decreases
the aggregate cash consideration payable in the Offer or changes the form of
consideration payable in the Offer (except to the extent QVC has made such
changes or has been granted benefits by the Company that diminish the value of
the Company to Purchaser); (ii) reduces the number of Shares to be purchased in
the Offer below 50.1% of the outstanding Shares on a fully diluted basis (as
defined below); provided, however, that the number of Shares sought in the Offer
can be decreased to not less than 50.1% of the outstanding Shares on a fully
diluted basis so long as the aggregate cash consideration payable in the Offer
is not decreased; or (iii) waives the Minimum Condition (which under no
circumstances may be less than 50.1% of the outstanding Shares on a fully
diluted basis). Subject to the provisions of the Exemption Agreement, Purchaser,
prior to being obligated to execute a merger agreement by the terms of the
Exemption Agreement, has in the Exemption Agreement expressly reserved the right
to terminate the Offer pursuant to its terms or to increase the price per Share
or the number of Shares for which tenders are sought in the Offer. The term
"fully diluted" as used in the Exemption Agreement means giving effect to the
Shares then outstanding plus the Shares issuable upon the exercise of the then
exercisable options.
 

     In order to cause the Offer and the QVC Offer to remain on the same time
schedule, Purchaser has agreed that if QVC remains subject to the QVC Merger
Agreement or remains subject to the form of exemption agreement attached
thereto, in either case containing terms substantially identical to the
Exemption Agreement for the benefit of the Company (the "Exemption Procedures"),
and (i) extends the expiration date of the QVC Offer (such expiration date, as
extended from time to time, being the "QVC Expiration Date") in accordance with
the Exemption Procedures, then the Expiration Date shall be extended (as soon as
practicable, but not later than one business day following the announcement of
the extension of the QVC Expiration Date) by Purchaser to the QVC Expiration
Date, or (ii) if upon notification to the Company by Purchaser and QVC of the
results of their respective offers (which notification will be required to be
delivered by Purchaser and QVC no later than promptly following the expiration
of their respective offers), the Company has notified Purchaser and QVC (which
notification shall be required to be delivered by the Company promptly) that a
number of Shares that would satisfy the Minimum Condition or the minimum
condition defined in the QVC Offer (which under no circumstances may be less
than 50.1% of the outstanding Shares on a fully diluted basis) (the "QVC Minimum
Condition") have not been validly tendered (and not withdrawn) pursuant to the
Offer or the QVC Offer, respectively, at the Expiration Date (or a number of
Shares that would satisfy the Minimum Condition and the QVC Minimum Condition
have been validly tendered and not withdrawn pursuant to both the Offer and the
QVC Offer at the Expiration Date), then Purchaser will extend the Expiration
Date for a period of ten business days. Purchaser will be subject to the
obligations set forth above in this paragraph and the obligations set forth in
"Termination of the Offer" for so long as QVC is subject to the Exemption
Procedures; provided, however, that Purchaser will not be subject to such
obligations in the event that QVC has not performed or complied in all material
respects with the Exemption Procedures.

 

     Recommendation of the Offer. Under the terms of the Exemption Agreement,
if, at any time, the Paramount Board recommends acceptance of the Offer by the
Company's stockholders, or informs Purchaser that the Paramount Board intends to
recommend acceptance of the Offer, then Purchaser will promptly execute and
deliver an executed Form of Merger Agreement (with representations and
warranties dated as of the date of execution of such Form of Merger Agreement,
unless otherwise specified therein and with such other changes as may be
necessary to reflect the terms of the Offer as it then exists, changes in the
consideration offered under the Form of Merger Agreement and changes related
thereto) as soon as practicable, but in no event more than one business day
thereafter, which Form of Merger Agreement will be executed by the Company (with
representations and warranties dated as of the date of such executed Form of
Merger Agreement, unless otherwise specified therein) within one business day of
receipt thereof.

 
                                       8

<PAGE>

     Receipt of Common Stock by Purchaser. In the event that a number of Shares
that would satisfy the Minimum Condition shall have been validly tendered and
not withdrawn in the Offer at the Expiration Date and, as of such Expiration
Date, Purchaser has waived all conditions to the Offer (other than the Minimum
Condition and the Rights Condition, the Supermajority Condition, the Section 203
Condition and the Injunction Condition), then Purchaser has agreed (i) to extend
the Expiration Date to a date ten business days from the then scheduled
Expiration Date, provided that such extension shall be for a period of five
business days in the event that the QVC Offer has been terminated prior to the
foregoing Expiration Date and (ii) promptly to deliver an executed Form of
Merger Agreement (with representations and warranties dated as of the date of
delivery to the Company of such executed Form of Merger Agreement, unless
otherwise specified therein and with such other changes as may be necessary to
reflect the terms of the Offer as it then exists, changes in the consideration
offered under the Form of Merger Agreement and changes related thereto), as soon
as practicable, but in no event more than one business day after the date of
such waiver, which Form of Merger Agreement will be executed by the Company
within one business day of receipt thereof (with representations and warranties
dated as of the date of such executed Form of Merger Agreement, unless otherwise
specified therein).

     Completion Certificate. At such time as Purchaser has fulfilled the terms
set forth in the immediately preceding paragraph, Purchaser will deliver to the
Paramount Board a certificate (the "Completion Certificate"), executed by an
authorized officer of Purchaser, certifying that all such terms have been
fulfilled.

     Termination of the Offer. Under the terms of the Exemption Agreement,
Purchaser has agreed to terminate the Offer at such time as Purchaser has been
notified pursuant to a certificate executed by an authorized officer of the
Company that: (i) a number of Shares that would satisfy the QVC Minimum
Condition shall have been validly tendered to the QVC Offer and not withdrawn at
the QVC Expiration Date; (ii) all conditions to the QVC Offer, except the QVC
Minimum Condition and the conditions relating to the Rights Agreement, Article
XI of the Company's Certificate of Incorporation, Section 203 of Delaware Law
and governmental or judicial injunction, each as set forth therein, shall have
been waived; and (iii) a completion certificate from QVC shall have been
delivered to the Company; provided, however, that Purchaser shall not be
required to terminate the Offer in the event that QVC has not performed or
complied in all material respects with the Exemption Procedures.
 
     Termination of Exemption Agreement. The Exemption Agreement terminates at
the earliest of (i) 9:00 A.M. on the first business day following the Final
Expiration Date, (ii) the execution and delivery by both Purchaser and the
Company of a Form of Merger Agreement, (iii) the delivery of notice by either
party to the Exemption Agreement in the event the other party materially
breaches any agreement or representation under the Exemption Agreement or (iv)
such time as Purchaser shall have terminated the Offer in accordance with the
terms thereof.
 
     Form of Merger Agreement. The Form of Merger Agreement is substantially
similar in form and substance to the Merger Agreement, except for the provisions
summarized below. The following summary is qualified in its entirety by
reference to the Form of Merger Agreement previously filed as Exhibit A to the
Exemption Agreement filed as an Exhibit to the Schedule 14D-1.
 
     (a) All references to the Stock Option Agreement and the $100 million
termination fee in the Merger Agreement have been eliminated in the Form of
Merger Agreement; provided, however, that each of the Company and Purchaser has
agreed that nothing contained in the Form of Merger Agreement will constitute a
waiver of any rights, claims or defenses of Purchaser or the Company created by
or arising under the Merger Agreement or the Stock Option Agreement, as amended,
all of which rights, claims and defenses are expressly reserved.
 
                                       9

<PAGE>
     (b) The provision contained in the Merger Agreement, which prohibited the
Company and Purchaser, and their respective subsidiaries and affiliates, under
certain specified circumstances, from (i) facilitating any inquiries or the
making of any proposal that constitutes or may be reasonably expected to lead to
a Competing Transaction (as defined below), (ii) entering into, maintaining or
continuing discussions or negotiations with any person or entity in furtherance
of such inquiries or to obtain a Competing Transaction, (iii) agreeing to or
endorsing any Competing Transaction or (iv) permitting any of their officers,
directors, employees or other representatives to take any such action, has been
eliminated in the Form of Merger Agreement.
 
     (c) Conditions to the obligations of each party to consummate the Merger
contained in the Merger Agreement, which relate to the receipt of certain
approvals from the FCC and other third parties, have been eliminated in the Form
of Merger Agreement.
 
     (d) In the Form of Merger Agreement, June 30, 1994 is the date on which
either the Company or Purchaser may terminate such agreement if the Merger shall
not have occurred. The corresponding date in the Merger Agreement was March 31,
1994.
 

     (e) In the Form of Merger Agreement, Purchaser has the right to terminate
such agreement if: (i) the Paramount Board withdraws, modifies or changes its
recommendation of such agreement, the Merger or the Offer in a manner adverse to
Purchaser or resolves to do any of the foregoing; provided that a statement by
the Paramount Board that it is neutral or unable to take a position with respect
to the Offer after the commencement or amendment of a tender offer by a third
party will not be deemed to constitute a withdrawal, modification or change of
its recommendation of such agreement if the Solicitation/Recommendation
Statement on Schedule 14D-9 relating to such third party tender offer recommends
rejection of such tender offer and the Paramount Board reconfirms its
recommendation of the Offer on the date of the filing thereof; (ii) the
Paramount Board recommends to the stockholders of the Company a Competing
Transaction; (iii) Purchaser has not consummated the Offer and a tender offer or
exchange offer for 30% or more of the outstanding shares of capital stock of the
Company is commenced, and the Paramount Board recommends that the stockholders
of the Company tender their shares in such tender or exchange offer; or (iv)
Purchaser has not consummated the Offer and any person acquires 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) has been formed which beneficially owns, or
has the right to acquire "beneficial ownership" (as defined in the Rights
Agreement) of, more than 30% of the then outstanding shares of capital stock of
the Company.

 
     (f) In the Form of Merger Agreement, the Company has the right to terminate
such agreement if, due to an occurrence or circumstance that would result in a
failure to satisfy any of the conditions of the Offer, (i) Purchaser has failed
to amend the Offer as provided in Section 2.1 of such agreement within ten
business days following the date thereof or (ii) the Offer expires without the
purchase of Shares thereunder.
 
     (g) In the Form of Merger Agreement, the term "Competing Transaction" means
any of the following involving the Company or any of the Company's subsidiaries:
(i) any merger, consolidation, share exchange, business combination, or other
similar transaction; (ii) any disposition of 30% or more of the assets of the
Company and the Company's subsidiaries, taken as a whole in a single transaction
or series of transactions; (iii) any tender offer or exchange offer for 30% or
more of the outstanding shares of capital stock of the Company or the filing of
a registration statement under the Securities Act in connection therewith; (iv)
any person having acquired 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 beneficial ownership of, 30% or more of the then outstanding
shares of capital stock of the Company; or (v) any
                                       10

<PAGE>
public announcement of a proposal, plan or intention to do any of the foregoing
or any agreement to engage in any of the foregoing.
 
     (h) In the Form of Merger Agreement, if either the Company or Purchaser
terminates such agreement and if Purchaser continues the Offer, the Exemption
Agreement will again become effective.
 
     (i) The Form of Merger Agreement provides that from and after the Effective
Time and until the tenth anniversary of the Effective Time, Purchaser will not
enter into any agreement with any stockholder (the "Majority Stockholder") who
beneficially owns more than 50% of the then outstanding securities entitled to
vote at a meeting of the stockholders of Purchaser that would constitute a Rule
13e-3 (as such rule is in effect on the date of the execution of the Form of
Merger Agreement) transaction under the Exchange Act with respect to any class
of common stock of Purchaser (any such transaction being a "Going Private
Transaction") unless Purchaser provides in any agreement pursuant to which such
Going Private Transaction will be effected that, as a condition to the
consummation of such Going Private Transaction, (a) the holders of a majority of
the shares of each class of common stock subject to such Going Private
Transaction and not beneficially owned by the Majority Stockholder that are
voted and present (whether in person or by proxy) at the meeting of stockholders
called to vote on such Going Private Transaction will have voted in favor
thereof and (b) a special committee (the "Special Committee") of the Board of
Directors of Purchaser comprised solely of the independent directors of
Purchaser will have (i) approved the terms and conditions of the Going Private
Transaction and will have recommended that the stockholders vote in favor
thereof and (ii) received from its financial advisor a written opinion addressed
to the Special Committee, for inclusion in the proxy statement to be delivered
to the stockholders, and dated the date thereof, substantially to the effect
that the consideration to be received by the stockholders (other than the
Majority Stockholder) in the Going Private Transaction is fair to them from a
financial point of view.
 

     (j) Pursuant to the Form of Merger Agreement, if requested by Purchaser,
the Company will, subject to Section 14(f) of the Exchange Act and Rule 14f-1
promulgated thereunder, promptly following the acceptance for payment of the
Shares, and from time to time thereafter, take all actions necessary to cause
a majority of directors of the Company (and of members of each committee of
the Paramount Board) and of each subsidiary of the Company to be designated by
Purchaser (whether, at the request of Purchaser, by means of increasing the
size of the Paramount Board or seeking the resignation of directors and
causing Purchaser's designees to be elected); provided that prior to receipt
by Purchaser of approval by the FCC of the Long Form Application, the Company
will take all actions necessary to elect Purchaser's voting trustee to the
Paramount Board.

 
     (k) The Form of Merger Agreement contains procedures applicable to the
terms of the Offer which are substantially identical to the terms of the
Exemption Agreement applicable to the Offer.
 
     5. CONDITIONS TO THE OFFER. The conditions to the Offer are hereby amended
and restated in their entirety as follows:
 

     Notwithstanding any other provision of the Offer, Purchaser will not be
required to accept for payment or pay for any Shares tendered pursuant to the
Offer, and may terminate or amend the Offer and may postpone the acceptance for
payment of and payment for Shares tendered, if (i) the Minimum Condition shall
not have been satisfied, (ii) the Paramount Board shall not have amended the
Rights Agreement to make the Rights inapplicable to the Offer and the Merger or
the Rights shall otherwise be applicable to the Offer and the Merger (the
"Rights Condition"), (iii) the Paramount Board shall not have taken all
necessary actions so as to make the restrictions on business combinations
contained in the supermajority voting requirement of Article XI of the Company's
Certificate of Incorporation inapplicable to the Offer and the Merger (the
"Supermajority Condition"), (iv) the Paramount Board shall not have taken all
necessary actions so as to make the restrictions on business combinations
contained in Section 203 of Delaware Law inapplicable to Purchaser in connection
with the Offer and the Merger
                                       11


<PAGE>
(the "Section 203 Condition") or (v) at any time on or after the date of this
Agreement, and prior to the acceptance for payment of Shares, any of the
following conditions shall not exist:
 

          (a) No governmental entity or federal or state court of competent
     jurisdiction shall have enacted, issued, promulgated, enforced or entered
     any statute, rule, 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
     Offer, the Merger or any transaction contemplated by the executed Form of
     Merger Agreement (if then in existence); provided that Purchaser shall have
     used all reasonable efforts to have any such order, decree or injunction
     vacated or reversed (the "Injunction Condition");

 

          (b) Each of the representations and warranties of the Company
     contained in the Form of Merger Agreement (as if such agreement had been
     duly executed by the Company) shall be true and correct, except (i) for
     changes specifically permitted by the Form of Merger 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 material adverse effect on the
     Company;

 

          (c) The Company shall have performed or complied in all material
     respects with all agreements and covenants required by the Form of Merger
     Agreement (as if such agreement had been duly executed by the Company) to
     be performed or complied with by it;

 
          (d) Since December 22, 1993, there shall have been no change,
     occurrence or circumstance in the business, results of operations or
     financial condition of the Company or any of its subsidiaries having or
     reasonably likely to have, individually or in the aggregate, a material
     adverse effect on the business, results of operations or financial
     condition of the Company and its subsidiaries, taken as a whole; or
 
          (e) Purchaser and the Company shall not have agreed that Purchaser
     shall terminate the Offer or postpone the acceptance for payment of or
     payment for Shares thereunder;
 
and, in the reasonable judgment of Purchaser in any such case, and regardless of
the circumstances (including any action or inaction by Purchaser or any of its
affiliates) giving rise to any such condition, it is inadvisable to proceed with
such acceptance for payment or payment.
 
     The foregoing conditions are for the sole benefit of Purchaser and may be
asserted by Purchaser regardless of the circumstances giving rise to any such
condition or may be waived by Purchaser in whole or in part at any time and from
time to time in its sole discretion. The failure by Purchaser at any time to
exercise any of the foregoing rights shall not be deemed a waiver of any such
right; the waiver of any such right with respect to particular facts and other
circumstances shall not be deemed a waiver with respect to any other facts and
circumstances; and each such right shall be deemed an ongoing right that may be
asserted at any time and from time to time.

     6. CERTAIN FEDERAL INCOME TAX AND OTHER TAX CONSEQUENCES. The discussion
set forth in Section 5 of the Offer to Purchase is hereby amended and
supplemented in its entirety as follows:


     The following summary, based upon current law, is a general discussion of
certain Federal income tax consequences of the Offer and the Merger to
Purchaser, the Company and stockholders of the Company. This summary is based
upon the Code, applicable Treasury regulations thereunder and administrative
rulings and judicial authority as of the date hereof. All of the foregoing are
subject to change, and any such change could affect the continuing validity of
this summary. This summary applies to stockholders of the Company who hold their
Shares as capital assets. This summary does not discuss all aspects of Federal
income taxation that may be relevant to a particular stockholder of the Company
in light of such stockholder's specific circumstances or to certain types of
stockholders subject to special treatment under the Federal income tax laws (for
example, foreign persons, dealers in securities, banks, insurance companies,
tax-exempt organizations and stockholders who acquired Shares pursuant to the
exercise of options or otherwise as compensation or through a tax-qualified
retirement plan), and it does not discuss any aspect of state, local, foreign or
other tax laws. No ruling has been (or will be) sought from the Internal Revenue
Service as to the anticipated tax consequences of the Offer or the Merger.


     Tax Consequences of the Offer and the Merger. If Shearman & Sterling,
counsel to Purchaser, is unable to deliver an opinion that the Merger will
qualify as a reorganization under section 368(a) of the Code, the Form of Merger
Agreement permits Purchaser to elect to cause a wholly owned subsidiary to merge
with and into the Company in the Merger. Based on the terms of the Offer and the
proposed terms of the Form of Merger Agreement, it is anticipated that Shearman
& Sterling will be unable to deliver such an opinion and that Purchaser will
therefore elect to change the form of the Merger. The election by Purchaser to
change the form of the Merger will, under applicable tax laws, prevent the
Company from having to recognize substantial taxable gain as a result of the
Merger's failing to qualify as a reorganization.


     Exchanges of Shares pursuant to the Offer or the Merger will be taxable
transactions for Federal income tax purposes. A stockholder of the Company who
exchanges Shares for cash in the Offer or for shares of Viacom Class B Common
Stock and Viacom Merger Preferred Stock in the Merger will recognize capital
gain or loss for Federal income tax purposes equal to the difference between
such stockholder's basis in the Shares so exchanged and the amount of cash
and/or the fair market value of the shares of Viacom Class B Common Stock and
Viacom Merger Preferred Stock received by such stockholder. Stockholders of the
Company should note that, in such circumstances, a stockholder who does not
receive any cash, but instead receives only shares of Viacom Class B Common
Stock and Viacom Merger Preferred Stock in the Merger nevertheless will
recognize taxable gain or loss. Such gain or loss will be long-term capital gain
or loss if, at the time of the Offer or the Merger, the Shares then exchanged
had been held for more than one year. Under current law, long-term capital gains
of individuals are, under certain circumstances, taxed at lower rates than items
of ordinary income (including short-term capital gains).


     Such stockholder of the Company will have a tax basis in the shares of
Viacom Class B Common Stock and Viacom Merger Preferred Stock received equal to
the fair market values of such shares on the date of the Merger. The holding
period of such stockholder of the Company in the Viacom Class B Common Stock and
Viacom Merger Preferred Stock received will begin on the day following the date
of the Merger.


     No gain or loss will be recognized by Purchaser or the Company as a result
of the Offer and the Merger.

 
     Backup Withholding. To prevent "backup withholding" of Federal income tax
on payments of cash to a stockholder of the Company who exchanges Shares for
cash in the Offer, a stockholder of the Company must, unless an exception
applies under the applicable law and regulations, provide the payor
                                       13

<PAGE>

of such cash with such stockholder's correct taxpayer identification number
("TIN") on a Substitute Form W-9 and certify under penalties of perjury that
such number is correct and that such stockholder is not subject to backup
withholding. A Substitute Form W-9 is included in the Letter of Transmittal. If
the correct TIN and certifications are not provided, a $50 penalty may be
imposed on a stockholder of the Company by the Internal Revenue Service, and
cash received by such stockholder in exchange for Shares in the Offer may be
subject to backup withholding of 31%.

 
     THE FEDERAL INCOME TAX CONSEQUENCES SET FORTH ABOVE ARE BASED UPON PRESENT
LAW, ARE FOR GENERAL INFORMATION ONLY AND DO NOT PURPORT TO BE A COMPLETE
ANALYSIS OR LISTING OF ALL POTENTIAL TAX EFFECTS WHICH MAY APPLY TO A
STOCKHOLDER OF THE COMPANY. THE TAX EFFECTS AS APPLICABLE TO A PARTICULAR
STOCKHOLDER OF THE COMPANY MAY BE DIFFERENT FROM THE TAX EFFECTS AS APPLICABLE
TO OTHER STOCKHOLDERS OF THE COMPANY, INCLUDING THE APPLICATION AND EFFECT OF
STATE, LOCAL AND OTHER TAX LAWS, AND THUS, STOCKHOLDERS OF THE COMPANY ARE URGED
TO CONSULT THEIR OWN TAX ADVISORS.

 
  Real Estate Transfer Taxes


     The New York State Real Property Transfer Gains Tax, the New York State
Real Estate Transfer Tax, and the New York City Real Property Transfer Tax
(collectively, the "Real Estate Transfer Taxes") are imposed on the transfer or
acquisition, directly or indirectly, of controlling interests in an entity which
owns interests in real property located in New York State or New York City, as
the case may be. The Offer and the Merger will result in the taxable transfer of
controlling interests in entities which own New York State or New York City real
property for purposes of the Real Estate Transfer Taxes. Although any Real
Estate Transfer Taxes could be imposed directly on the stockholders of the
Company, Purchaser and the Company will complete and file any necessary tax
returns, and Purchaser will pay all Real Estate Transfer Taxes that are imposed
as a result of the Offer and the Merger. Upon receipt of the consideration for
either the Offer or the Merger, each stockholder of the Company will be deemed
to have agreed to be bound by the Real Estate Transfer Tax returns filed by
Purchaser and the Company.

 
     7. PURPOSE OF THE OFFER; PLANS FOR THE COMPANY AFTER THE OFFER AND THE
MERGER. The discussion set forth in Section 11 of the Offer to Purchase is
hereby amended and supplemented as follows:

 
     Purchaser is actively preparing plans for the combination of Purchaser,
the Company and Blockbuster and their respective businesses and management.
Purchaser intends to integrate the businesses of Purchaser, Blockbuster and
the Company in order to achieve efficiencies and to create value based upon the
complementary businesses and brands of the combined companies. Purchaser has
no present intention of disposing of any significant assets of Purchaser,
Blockbuster or the Company following consummation of the Offer.

 
     8. CERTAIN LEGAL MATTERS AND REGULATORY APPROVALS. The discussion set forth
in Section 15 of the Offer to Purchase and Section 5 of the First Supplement is
hereby amended and supplemented as follows:

 
     Delaware Litigation. On December 14, 1993, the plaintiffs in In re
Paramount Communications Inc. Shareholders Litigation, Consolidated Civ. Action
No. 13117, made a motion for the entry of an order modifying the preliminary
injunction granted by the Delaware Chancery Court on November 24, 1993, to
enjoin the termination fee payable to Purchaser pursuant to the Merger
Agreement.
 
     Federal Antitrust Litigation. On November 9, 1993, Purchaser amended its
complaint in federal court in Viacom International Inc. v. Tele-Communications,
Inc., et al., Case No. 93 Civ. 6658, by
                                       14

adding Comcast Corporation as an additional defendant and incorporating claims
of additional anticompetitive activities by the defendants.
 
     FCC Approval. On November 23, 1993, the FCC approved Purchaser's STA
Application to acquire Shares pursuant the Offer, thereby satisfying the FCC
Condition to consummation of the Offer.
 

     9. CERTAIN INFORMATION CONCERNING PURCHASER. The discussion set forth in
Section 8 of the Offer to Purchase is hereby amended and supplemented as
follows:

 
     General. On November 18, 1993, William C. Ferguson was elected to the Board

THE BLOCKBUSTER MERGER AGREEMENT

 
     The following is a summary of the Blockbuster Merger Agreement, a copy of
which is filed as an Exhibit to the Schedule 14D-1. Such summary is qualified in
its entirety by reference to the Blockbuster Merger Agreement.


     The Blockbuster Merger. The Blockbuster Merger Agreement provides that,
upon the terms and subject to the conditions thereof, at the effective time of
the Blockbuster Merger (the "Blockbuster Merger Effective Time"), Blockbuster
will be merged with and into Purchaser in accordance with Delaware Law. As a
result of the Blockbuster Merger, the separate corporate existence of
Blockbuster will cease and Purchaser will continue as the Blockbuster Merger
Surviving Corporation.


     At the Blockbuster Merger Effective Time, each issued and then outstanding
share of common stock, par value $1.00 per share, of Blockbuster (the
"Blockbuster Shares") (other than any Blockbuster Shares held in the treasury of
Blockbuster, or owned by Purchaser or any direct or indirect wholly owned
subsidiary of Purchaser or of Blockbuster and any dissenting shares (if
applicable)) shall be converted automatically into the right to receive (x) .08
of one share of Viacom Class A Common Stock, (y) .60615 of one share of Viacom
Class B Common Stock and (z) 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 Purchaser having the principal terms described in
Annex A to the Blockbuster Merger Agreement (collectively, the "Blockbuster
Merger Consideration").

 
     In addition, employee stock options and warrants outstanding at the 
Blockbuster Merger Effective Time will become exercisable thereafter for the 
Blockbuster Merger Consideration. Pursuant to the terms of the Blockbuster
stock option plans, the vesting of employee stock options will be accelerated
in connection with the Blockbuster Merger.

     As of December 31, 1993, there were 247,487,375 Blockbuster Shares
outstanding. In addition, there were 18,564,443 Blockbuster Shares subject to
outstanding stock options and warrants. Based thereon, an aggregate of 
approximately 19.8 million shares of Viacom Class A Common Stock and 149.9 
million shares of Viacom Class B Common Stock, and VCRs representing a maximum 
of approximately 34.2 million additional shares of Viacom Class B Common Stock
would be issuable in the Blockbuster Merger. In addition, an aggregate of
approximately 1.5 million additional shares of Viacom Class A Common Stock and
11.3 million additional shares of Viacom Class B Common Stock, and VCRs
representing a maximum of approximately 2.6 million additional shares of
Viacom Class B Common Stock would be issuable in connection with the possible
exercise of stock options and warrants.


     The Blockbuster Merger Agreement provides that, at the Blockbuster Merger
Effective Time, the Restated Certificate of Incorporation and the By-Laws of
Purchaser, as in effect immediately prior to the Blockbuster Merger Effective
Time, will be the Certificate of Incorporation and the By-Laws of the
Blockbuster Merger Surviving Corporation.


     Agreements of Purchaser and Blockbuster. The Blockbuster Merger Agreement
contains various customary covenants and agreements of the parties thereto,
including agreements as to the calling of meetings of the respective
stockholders of Purchaser and Blockbuster, the making of certain filings under
the federal securities laws with respect to such stockholders' meetings and the
transactions contemplated by the Blockbuster Merger Agreement, and the operation
of the parties' respective businesses prior to the Blockbuster Merger Effective
Time. In addition, pursuant to the Blockbuster Merger Agreement, until the tenth
anniversary of the Blockbuster Merger Effective Time Purchaser is subject to
substantially the same restrictions on Going Private Transactions as are
contained in the Form of Merger Agreement.


     Representations and Warranties. The Blockbuster Merger Agreement contains
various customary representations and warranties of the parties thereto.

     Certain Other Agreements. Certain stockholders of Blockbuster have granted
to Purchaser options to purchase the shares of common stock of Blockbuster owned
by such stockholders in certain circumstances in the event the Blockbuster
