disabilities and duties of the Surviving Corporation.

          SECTION 1.04. Certificate of Incorporation and By-Laws. (a) The
Restated Certificate of Incorporation of Viacom, as in effect immediately
prior to the Effective Time, shall be amended as of the Effective Time to be

amended, such Restated Certificate of Incorporation shall be the certificate
of incorporation of the Surviving Corporation until thereafter changed or
amended as provided therein or by applicable law.

          (b) The By-laws of Viacom, as in effect immediately prior to the
Effective Time, shall be amended as of the Effective Time so as to read in

                                 ARTICLE II

             CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES

          SECTION 2.01. Conversion of Securities. At the Effective Time, by
virtue of the Merger and without any action on the part of Viacom, CBS or
the holders of any of the following securities:

                  (a) Each share of common stock, par value $1.00 per share, of
         CBS ("CBS Common Stock"; all issued and outstanding shares of CBS
         Common Stock being hereinafter collectively referred to as the
         "Shares") issued and outstanding immediately prior to the Effective
         Time (other than any Shares to be cancelled or converted pursuant to
         Section 2.01(b)) shall be converted, subject to Section 2.02(e), into
         the right to receive 1.085 shares (the "Exchange Ratio") of Viacom
         Class B Common Stock.

                  (b) Each Share held in the treasury of CBS and each Share
         owned by Viacom immediately prior to the Effective Time shall be
         cancelled and extinguished without any conversion thereof and no
         payment shall be made with respect thereto, and each Share owned by any
         direct or indirect wholly owned subsidiary of Viacom or CBS (other than
         Shares held by benefit plans or trusts (including Rabbi trusts))
         immediately prior to the Effective Time shall be converted into the
         right to receive a number of shares of Viacom Class B Common Stock
         equal to the Exchange Ratio.

                  (c) If, prior to the Effective Time (and as permitted by
         Sections 5.01 and/or 5.02), the outstanding Shares or shares of Viacom
         Class B Common Stock shall have been increased, decreased, changed into
         or exchanged for a different number or class of shares or securities as
         a result of a reorganization, recapitalization, reclassification, stock
         dividend, stock split, reverse stock split, combination or exchange of
         shares or other similar change in capitalization, then an appropriate
         and proportionate adjustment shall be made to the Exchange Ratio.

          SECTION 2.02. Exchange of Certificates. (a) Exchange Agent. Viacom
shall deposit, or shall cause to be deposited, with such bank or trust
company designated by Viacom and reasonably acceptable to CBS (the "Exchange
Agent"), for the benefit of the holders of Shares, for exchange in
accordance with this Article II through the Exchange Agent, certificates
representing the shares of Viacom Class B Common Stock (such certificates
for shares of Viacom Class B Common Stock, together with any dividends or
distributions with respect thereto and any cash in lieu of fractional shares
of Viacom Class B Common Stock payable pursuant to Section 2.02(e), being
hereinafter referred to as the "Exchange Fund") issuable pursuant to Section
2.01 in exchange for outstanding Shares. The Exchange Agent shall, pursuant
to irrevocable instructions, deliver the Viacom Class B Common Stock
contemplated to be issued pursuant to Section 2.01 out of the Exchange Fund.
Except as contemplated by Section 2.02(f) hereof, the Exchange Fund shall
not be used for any other purpose.


<PAGE>


          (b) Exchange Procedures. As promptly as practicable after the
Effective Time, Viacom shall cause the Exchange Agent to mail to each holder
of a certificate or certificates which immediately prior to the Effective
Time represented outstanding Shares (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 customary form)
and (ii) instructions for use in effecting the surrender of the Certificates
in exchange for certificates representing whole shares of Viacom Class B
Common Stock, together with any dividends or distribution with respect
thereto and any cash in lieu of fractional shares. Upon surrender to the
Exchange Agent of a Certificate for exchange and cancellation, together with
such letter of transmittal, duly executed, and such other documents as may
be required pursuant to such instructions, the holder of such Certificate
shall be entitled to receive in exchange therefor a certificate representing
that number of whole shares of Viacom Class B Common Stock which such holder
has the right to receive in respect of the Shares formerly represented by
such Certificate (after taking into account all Shares then held by such
holder), cash in lieu of fractional shares of Viacom Class B Common Stock to
which such holder is entitled pursuant to Section 2.02(e) and any dividends
or other distributions to which such holder is entitled pursuant to Section
2.02(c), and the Certificate so surrendered shall forthwith be cancelled. In
the event of a transfer of ownership of Shares that is not registered in the
transfer records of CBS, a certificate representing the proper number of
shares of Viacom Class B Common Stock may be issued to a transferee if the
Certificate representing such Shares 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 represent only the
right to receive upon such surrender the certificate representing shares of
Viacom Clss B Common Stock, cash in lieu of any fractional shares of Viacom
Class B Common Stock to which such holder is entitled pursuant to Section
2.02(e) and any dividends or other distributions to which such holder is
entitled pursuant to Section 2.02(c).

          (c) Distributions with Respect to Unexchanged Shares of Viacom
Class B Common Stock. No dividends or other distributions 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 Class B Common Stock
represented thereby, and no cash payment in lieu of fractional shares shall
be paid to any such holder pursuant to Section 2.02(e), until the holder of
such Certificate shall surrender such Certificate. Subject to the effect of
escheat, Tax (as defined in Section 3.14) or other applicable Laws (as
defined in Section 3.05), following surrender of any such Certificate, there
shall be paid to the record holder thereof, without interest, (i) promptly,
the amount of any cash payable with respect to a fractional share of Viacom
Class B Common Stock to which such holder is entitled pursuant to Section
2.02(e) and the amount of dividends or other distributions with a record
date after the Effective Time and theretofore paid with respect to such
whole shares of Viacom Class B Common Stock, and (ii) at the appropriate
payment date, the amount of dividends or other distributions with a record
date after the Effective Time and a payment date occurring after surrender,
payable with respect to such whole shares of Viacom Class B Common Stock.

          (d) No Further Rights in CBS Common Stock. All shares of Viacom
Class B Common Stock issued upon conversion of the Shares in accordance with
the


<PAGE>


terms hereof (including any cash paid pursuant to Sections 2.02(c) or (e)) shall
be deemed to have been issued in full satisfaction of all rights pertaining to
such Shares.

          (e) No Fractional Shares. No certificates or scrip representing
fractional shares of Viacom Class B Common Stock shall be issued upon the
surrender for exchange of Certificates, and such fractional share interests
will not entitle the owner thereof to vote or to any other rights of a
stockholder of Viacom. Each holder of a fractional share interest shall be
paid an amount in cash equal to the product obtained by multiplying (i) such
fractional share interest to which such holder (determined after taking into
account all fractional share interests then held by such holder) would
otherwise be entitled by (ii) the closing price for a share of Viacom Class
B Common Stock on the Consolidated Tape, Network A, as reported in The Wall
Street Journal (Northeast edition) or any other authoritative source on the
first trading day immediately following the Effective Time. From time to
time after the Effective Time, as promptly as practicable after the
determination of the amount of cash, if any, to be paid to any holders of
fractional share interests who have surrendered their Certificates to the
Exchange Agent, the Exchange Agent shall so notify Viacom, and Viacom shall
deposit such amount with the Exchange Agent and shall cause the Exchange
Agent to forward payments to such holder of fractional share interests
subject to and in accordance with the terms of Sections 2.02(b) and (c).

          (f) Termination of Exchange Fund. Any portion of the Exchange Fund
which remains undistributed to the holders of CBS Common Stock for six (6)
months after the Effective Time shall be delivered to Viacom, upon demand,
and any holders of CBS Common Stock who have not theretofore complied with
this Article II shall thereafter look only to Viacom for the shares of
Viacom Class B Common Stock, any cash in lieu of fractional shares of Viacom
Class B Common Stock to which they are entitled pursuant to Section 2.02(e)
and any dividends or other distributions with respect to Viacom Class B
Common Stock to which they are entitled pursuant to Section 2.02(c). Any
portion of the Exchange Fund remaining unclaimed by holders of Shares as of
a date which is immediately prior to such time as such amounts would
otherwise escheat to or become property of any government entity shall, to
the extent permitted by applicable Law, become the property of Viacom free
and clear of any claims or interest of any person previously entitled
thereto.

          (g) No Liability. Neither Viacom nor CBS shall be liable to any
holder of Shares for any such Shares (or dividends or distributions with
respect hereto) or cash delivered to a public official pursuant to any
abandoned property, escheat or similar Law.

          (h) Lost, Stolen or Destroyed Certificates. In the event that any
Certificate has been lost, stolen or destroyed, upon the making of an
affidavit of that fact by the person claiming such Certificate to be lost,
stolen or destroyed and, if required by Viacom, the posting by such person
of a bond in such reasonable amount as Viacom may direct as indemnity
against any claim that may be made against it with respect to such
Certificate, Viacom will, in exchange for such lost, stolen or destroyed
Certificate, issue or cause to be issued the number of whole shares of
Viacom Common Stock and pay or cause to be paid the amounts deliverable in
respect thereof pursuant to Section 2.02(e) and 2.02(c).

          (i) Withholding Rights. Viacom shall be entitled to deduct and
withhold from the consideration otherwise payable pursuant to this Agreement
to any holder of


<PAGE>


Shares such amounts as it 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, such
withheld amounts shall be treated for all purposes of this Agreement as having
been paid to the holder of the Shares in respect of which such deduction and
withholding was made by Viacom.

          SECTION 2.03. Stock Transfer Books. At the Effective Time, the
stock transfer books of CBS shall be closed and there shall be no further
registration of transfers of Shares thereafter on the records of CBS. From
and after the Effective Time, the holders of Certificates shall cease to
have any rights with respect to such Shares except as otherwise provided
herein or by any Laws. On or after the Effective Time, any Certificates
presented to the Exchange Agent or Viacom for any reason shall be converted
into shares of Viacom Class B Common Stock, any cash in lieu of fractional
shares of Viacom Class B Common Stock to which the holders thereof are
entitled pursuant to Section 2.02(e) and any dividends or other
distributions to which the holders thereof are entitled pursuant to Section
2.02(c).

          SECTION 2.04. Stock Options and Other Stock Plans. (a) Prior to
the Effective Time, Viacom and CBS shall take such action as may be
necessary to cause each unexpired and unexercised option or warrant to
purchase Shares which are outstanding immediately prior to the Effective
Time (collectively, "CBS Options"), whether granted under CBS's stock option
plans set forth in Section 2.04 of the CBS Disclosure Schedule (as defined
below) or otherwise, to be automatically converted at the Effective Time
into an option or warrant (collectively, a "Substituted Option") to purchase
a number of shares of Viacom Class B Common Stock equal to the number of
Shares that could have been purchased (assuming full vesting) under such CBS
Option multiplied by the Exchange Ratio (rounded to the nearest whole number
of shares of Viacom Class B Common Stock) at a price per share of Viacom
Class B Common Stock equal to the per-share option exercise price specified
in the CBS Option divided by the Exchange Ratio (rounded down to the nearest
whole cent). Except as otherwise provided in this Agreement, such
Substituted Option shall otherwise be subject to the same terms and
conditions as such CBS Option (except that all vesting periods with respect
thereto shall, to the extent provided by the terms thereof, accelerate, and
be subject to any other rights which arise under the CBS Stock Option Plans
or the option agreements evidencing awards thereunder as a result of the
transactions contemplated by this Agreement). The date of grant of the
Substituted Option shall be the date on which the corresponding CBS Option
was granted. At the Effective Time, (i) all references in the related stock
option agreements to CBS shall be deemed to refer to Viacom and (ii) Viacom
shall assume all of CBS's obligations with respect to CBS Options as so
amended. As promptly as reasonably practicable after the Effective Time,
Viacom shall issue to each holder of an outstanding CBS Option a document
evidencing the foregoing assumption by Viacom. Employee and director
deferrals and director common stock equivalents and all other equity based
compensation that references CBS Common Stock will as of and after the
Effective Time, be deemed to refer to Viacom Class B Common Stock (as
adjusted to reflect the Exchange Ratio).

          (b) In respect of each CBS Option assumed by Viacom, and the
shares of Viacom Class B Common Stock underlying such CBS Option, Viacom
shall, no later than one Business Day after the Effective Time, file and
keep current a Form S-8 or other appropriate registration statement for as
long as any Substituted Options remain outstanding.



<PAGE>


          (c) Prior to the Effective Time, Viacom and CBS shall take all
steps reasonably necessary to cause the transactions contemplated hereby and
any other dispositions of equity securities of CBS (including derivative
securities) or acquisitions of Viacom equity securities (including
derivative securities) in connection with this Agreement by each individual
who (a) is a director or officer of Viacom or (b) at the Effective Time,
will become a director or officer of Viacom, to be exempt under Rule 16b-3
promulgated under the Securities Exchange Act of 1934, as amended (the
"Exchange Act").


                                 ARTICLE III

                    REPRESENTATIONS AND WARRANTIES OF CBS

          Except as disclosed in the report on Form 10-K dated March 24,
1999 for the year ended December 31, 1998, the Reports on Form 10-K/A, Form
10-Q, Form 10-Q/A and Form 8-K since December 31, 1998 or the proxy
statement dated March 25, 1999, in each case in the form filed by CBS with
the United States Securities and Exchange Commission (the "SEC") or in a
separate disclosure schedule which has been delivered by CBS to Viacom prior
to the execution of this Agreement (the "CBS Disclosure Schedule") (each
section of which qualifies the correspondingly numbered representation and
warranty or covenant to the extent specified therein and such other
representations and warranties or covenants to the extent a matter in such
section is disclosed in such a way as to make its relevance to the
information called for by such other representation and warranty or covenant
readily apparent), CBS hereby represents and warrants to Viacom:

          SECTION 3.01. Organization and Qualification; Subsidiaries. Each
of CBS and its subsidiaries is a corporation or entity duly incorporated or
formed, validly existing and in good standing under the laws of its
jurisdiction of incorporation or formation and has the requisite corporate
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 have such power, authority and
governmental approvals would not have a CBS Material Adverse Effect (as
defined below). Each of CBS and its subsidiaries 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 have a CBS Material Adverse Effect. The
term "CBS Material Adverse Effect" means any change, effect or circumstance
that is or is reasonably likely to be materially adverse to the business,
results of operations or financial condition of CBS and its subsidiaries
taken as a whole, other than any change, effect or circumstance relating to
or resulting from (i) general changes in the media or entertainment
industries or the advertising markets, (ii) changes in general economic
conditions or securities markets in general or (iii) this Agreement or the
transactions contemplated hereby or the announcement thereof.

          SECTION 3.02. Certificate of Incorporation and By-Laws. CBS has
made available to Viacom a complete and correct copy of the Articles of
Incorporation and the By-


<PAGE>


laws, each as amended to date, of CBS and Infinity Broadcasting Corporation,
a Delaware corporation ("Infinity"). The Articles of Incorporation and
Bylaws (or equivalent organizational documents) of CBS and its subsidiaries
are in full force and effect. Except as would not have a CBS Material
Adverse Effect, none of CBS or its subsidiaries is in violation of any
provision of its Articles of Incorporation or Bylaws (or equivalent
organizational documents).

          SECTION 3.03. Capitalization. The authorized capital stock of CBS
consists of 1,100,000,000 Shares and 25,000,000 shares of preferred stock,
par value $1.00 per share (the "CBS Preferred Stock"). As of August 31,
1999, (a) 705,119,425 Shares were issued and outstanding, all of which were
validly issued, fully paid and nonassessable, (b) 40,099,599 Shares were
held in the treasury of CBS, (c) 51,007,538 Shares were reserved for future
issuance pursuant to outstanding unexercised employee stock options granted
pursuant to the CBS stock option plans or otherwise and (d) 70,365,195
Shares were reserved for future issuance in connection with the merger of a
wholly owned subsidiary of CBS with and into King World Productions, Inc.
("King World") and 9,910,600 (or some equivalent amount of CBS Preferred
Stock, if appropriate), measured at the September 3, 1999 New York Stock
Exchange (the "NYSE") closing price, were reserved for future issuance in
connection with the acquisition from Gaylord Entertainment Company of
television station KVTV, Dallas/Fort Worth, Texas. As of the date of this
Agreement, no shares of CBS Preferred Stock are outstanding. As of the date
of this Agreement, except for the issuance of Shares pursuant to the
exercise of CBS Options and options to purchase 5,850,555 shares of Class A
Common Stock, par value $0.01 per share, of Infinity, outstanding prior to
August 31, 1999, no shares of capital stock of CBS or any of its
subsidiaries have been issued since August 31, 1999. Except as set forth in
this Section 3.03, and except for the Series A participating preferred stock
purchase rights of CBS (the "Rights") issued pursuant to the Rights
Agreement, dated as of December 28, 1995, between CBS and First Chicago
Trust Company of New York (the "CBS Rights Agreement"), as of the date of
this Agreement there are no options, warrants or other rights, agreements
(including registration rights agreements), arrangements or commitments of
any character relating to the issued or unissued capital stock of CBS or any
of its subsidiaries or obligating CBS or any of its subsidiaries to issue or
sell any shares of capital stock of, or other equity interests in, CBS or
any of its subsidiaries. All shares of capital stock of CBS and its
subsidiaries 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. As of the date of this Agreement, there are no outstanding
contractual material obligations of CBS or any subsidiary to repurchase,
redeem or otherwise acquire any shares of capital stock of CBS or any of its
subsidiaries or to provide material funds to, or make any material
investment (in the form of a loan capital contribution or otherwise) in, any
person.

          SECTION 3.04. Authority Relative to Agreement. CBS has all
necessary power and authority to execute and deliver this Agreement, to
perform its obligations hereunder and to consummate the Merger and the other
transactions contemplated hereby. The execution and delivery of this
Agreement by CBS and the consummation by CBS of the Merger and the other
transactions contemplated hereby have been duly and validly authorized by
all necessary corporate action and no other corporate proceedings on the
part of CBS are necessary to authorize the execution and delivery of this
Agreement or to consummate the Merger and the other transactions
contemplated hereby (other than, with respect to the Merger, the adoption of
this Agreement by the affirmative vote of a majority of the votes cast by
all shareholders entitled to vote at the CBS Stockholders' Meeting (as
defined in Section 6.02) and the filing and recordation of


<PAGE>


appropriate merger documents as required by Pennsylvania Law). This Agreement
has been duly and validly executed and delivered by CBS and, assuming the due
authorization, execution and delivery by Viacom, this Agreement constitutes a
legal, valid and binding obligation of CBS, enforceable against CBS in
accordance with its terms.

          SECTION 3.05. No Conflict; Required Filings and Consents. (a) The
execution and delivery of this Agreement by CBS does not, and the
performance of this Agreement by CBS will not, (i) conflict with or violate
the Articles of Incorporation or By-laws of (A) CBS or Infinity or (B) any
of its other subsidiaries, (ii) assuming the consents, approvals,
authorizations and waivers specified in Section 3.05(b) have been received
and the waiting periods referred to therein have expired, and any condition
precedent to such consent, approval, authorization, or waiver has been
satisfied, conflict with or violate any domestic (federal, state or local)
or foreign law, rule, regulation, order, judgment or decree (collectively,
"Laws") applicable to CBS or any of its subsidiaries or by which any
property or asset of CBS or any of its subsidiaries 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, 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 CBS or any of its subsidiaries pursuant to, any note, bond,
mortgage, indenture or credit agreement, or, to CBS's knowledge as of the
date of this Agreement, any other contract, agreement, lease, license,
permit, franchise or other instrument or obligation to which CBS or any of
its subsidiaries is a party or by which CBS or any of its subsidiaries or
any property or asset of CBS or any of its subsidiaries is bound or
affected, except, in the case of clauses (i)(B), (ii) and (iii), for any
such conflicts, violations, breaches, defaults or other occurrences of the
type referred to above which would not have a CBS Material Adverse Effect or
would not prevent or materially delay the consummation of the Merger;
provided, however, that for purposes of this Section 3.05(a), the definition
of CBS Material Adverse Effect shall be read so as not to include clause
(iii) of the definition thereof.

          (b) The execution and delivery of this Agreement by CBS do not,
and the performance of this Agreement by CBS will not, require any consent,
approval, authorization, waiver or permit of, or filing with or notification
to, any governmental or regulatory authority, domestic, foreign or
supranational, except for applicable requirements of the Exchange Act, the
Securities Act of 1933, as amended (the "Securities Act"), state securities
or "blue sky" laws ("Blue Sky Laws"), the pre-merger notification
arrangements of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended, and the rules and regulations thereunder (the "HSR Act"), such
filings, approvals and waivers of the Federal Communications Commission or
any successor entity (the "FCC") as may be required under the Communications
Act of 1934, as amended, and the rules, regulations and of the FCC
thereunder (collectively, the "Communications Act"), applicable requirements
of the Investment Canada Act of 1985 and the Competition Act (Canada), any
other non-United States competition, antitrust and investment law, filing
and recordation of appropriate merger documents as required by Delaware Law
and Pennsylvania Law and the rules of the NYSE and except where failure to
obtain such consents, approvals, authorizations or permits, or to make such
filings or notifications, would not have a CBS Material Adverse Effect or
would not prevent or materially delay the consummation of the Merger;
provided, however, that for


<PAGE>


purposes of this Section 3.05(b), the definition of CBS Material Adverse Effect
shall be read so as not to include clause (iii) of the definition thereof.

          SECTION 3.06. Permits and Licenses; Contracts. (a) Each of CBS and
its subsidiaries is in possession of all franchises, grants, authorizations,
licenses, permits, easements, variances, exceptions, consents, certificates,
approvals and orders necessary for CBS or any of its subsidiaries to own,
lease and operate the properties of CBS and its subsidiaries or to carry on
their business as it is now being conducted and contemplated to be conducted
(the "CBS Permits"), and no suspension or cancellation of any of the CBS
Permits is pending or, to the knowledge of CBS, threatened, except where the
failure to have, or the suspension or cancellation of, any of the CBS
Permits would not have a CBS Material Adverse Effect. None of CBS or any of
its subsidiaries is in conflict with, or in default or violation of, (i) any
Laws applicable to CBS or any of its subsidiaries or by which any property
or asset of CBS or any of its subsidiaries is bound or affected, (ii) any of
the CBS Permits or (iii) any note, bond, mortgage, indenture, contract,
agreement, lease, license, permit, franchise or other instrument or
obligation to which CBS or any of its subsidiaries is a party or by which
CBS or any of its subsidiaries or any property or asset of CBS or any of its
subsidiaries is bound or affected, except for any such conflicts, defaults
or violations that would not have a CBS Material Adverse Effect.

          (b) Except as would not have a CBS Material Adverse Effect, and to
the knowledge of CBS, except as would not have a material adverse effect on
the Surviving Corporation following the Effective Time, none of CBS or any
of its subsidiaries is a party to any contracts or agreements that limits
the ability of CBS or any of its subsidiaries or, after the Effective Time,
Viacom or any of its subsidiaries, to compete in any line of business or
with any person or engage in any business in any geographic area, in each
case except for competition in businesses that neither CBS nor Viacom are
currently engaged in or will reasonably foreseeably engage in.

          (c) CBS and its subsidiaries have operated the radio and
television stations and associated facilities for which CBS or any of its
subsidiaries holds licenses from the FCC, in each case which are owned or
operated by CBS and its subsidiaries (the "CBS Licensed Facilities"), in
material compliance with the terms of the CBS Permits issued by the FCC to
CBS and its subsidiaries ("CBS FCC Licenses"), and in material compliance
with the Communications Act, and CBS and its subsidiaries have timely filed
or made all applications, reports and other disclosures required by the FCC
to be filed or made with respect to the CBS Licensed Facilities and have
timely paid all FCC regulatory fees with respect thereto, in each case
except as would not have a CBS Material Adverse Effect. As of the date
hereof, to CBS's knowledge, there is not now pending or threatened before
the FCC any material investigation, proceeding, notice of violation, order
of forfeiture or complaint against CBS or any of its subsidiaries, relating
to any of the CBS Licensed Facilities or FCC regulated services conducted by
CBS that, if adversely decided, would have a CBS Material Adverse Effect.

          SECTION 3.07. SEC Filings; Financial Statements. (a) CBS and
Infinity have filed all forms, reports and documents required to be filed by
it with the SEC from December 31, 1996 to the date of this Agreement,
including: (i) Annual Reports on Form 10-K, (ii) Quarterly Reports on Form

thereunder, (ii) 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

maintained or contributed to by CBS or any of its subsidiaries, or with
respect to which CBS or any of its subsidiaries could incur liability under
Section 4069 of ERISA, other than multiemployer plans within the meaning of
Section 3(37) of ERISA (the "CBS Benefit Plans"), CBS will provide to Viacom
within 15 days of the date of this Agreement a true and correct copy of (i)

liability in connection with (i) the termination or reorganization of any
employee benefit plan subject to Title IV of ERISA or (ii) the withdrawal

its or its subsidiaries' employees; and (iii) copies of all material plans,
programs, agreements and other arrangements of CBS or any of its
subsidiaries with or relating to its or its subsidiaries' employees which
contain change in control provisions. Neither the execution and delivery of
this Agreement nor the consummation of the transactions contemplated hereby
will (i) result in any payment (including, without limitation, severance,
unemployment compensation, "golden parachute" or otherwise) becoming due to
any director, officer or employee of CBS or any of its subsidiaries from CBS
or any of its affiliates under any CBS Benefit Plan or otherwise, which
payment is material in relation to the compensation previously provided to

Plan, which increase is material in relation to the benefits previously
provided or (iii) result in any acceleration of the time of payment or

a favorable determination letter from the IRS covering all of the provisions
applicable to the Plan for which determination letters are currently
available that the CBS Benefit Plan is so qualified and each trust
established in connection with any CBS Benefit Plan which is intended to be
exempt from federal income taxation under Section 501(a) of the Code has
received a determination letter from the IRS that it is so exempt, and no
fact or event has occurred since the date of such determination letter or
letters from the IRS which is reasonably likely to adversely affect the
qualified status of any such CBS Benefit Plan or the exempt status of any
such trust.

CBS Material Adverse Effect. There is no charge or complaint against CBS or
any of its subsidiaries by the National Labor Relations Board or any
comparable state agency pending or threatened in writing, except for such
charges or complaints (or related unfair labor practices) which would not
have a CBS Material Adverse Effect.

          SECTION 3.12. Environmental Matters. Except as would not,
individually or in the aggregate, have a CBS Material Adverse Effect:

          (a) CBS and its subsidiaries (i) are in compliance with all, and

     subsidiaries is listed or, to the knowledge of CBS, proposed for
     listing on the "National Priorities List" under CERCLA, as updated

          For purposes of this Agreement:

          SECTION 3.15. Tax Matters. None of CBS or any of its affiliates
has taken or agreed to take any action that would prevent the Merger from

<PAGE>


          SECTION 3.16. Year 2000 Compliance. (a) CBS has adopted a plan

                                 ARTICLE IV

                  REPRESENTATIONS AND WARRANTIES OF VIACOM

          Except as disclosed in the report on Form 10-K dated March 31,
1999 for the year ended December 31, 1998, the reports on Form 10-Q and Form

each case in the form filed by Viacom with the SEC or in a separate
disclosure schedule which has been delivered by Viacom to CBS prior to the
execution of this Agreement (the "Viacom Disclosure Schedule") (each section
of which qualifies the correspondingly numbered representation and warranty
or covenant to the extent specified therein and such other representations
and warranties or covenants to the extent a matter in such section is
disclosed in such a way as to make its relevance to the information called
for by such other representation and warranty or covenant readily apparent),
Viacom hereby represents and warrants to CBS that:

          SECTION 4.01. Organization and Qualification; Subsidiaries. Each
of Viacom and its subsidiaries is a corporation or entity duly incorporated
or formed, validly existing and in good standing, under the laws of its
jurisdiction of incorporation or formation, and has the requisite corporate
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 have such power, authority and
governmental approvals would not have a Viacom Material Adverse Effect (as
defined below). Each of Viacom and its subsidiaries 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 have a Viacom Material Adverse Effect.
The term "Viacom Material Adverse Effect" means any change, effect or
circumstance that is or is reasonably likely to be materially adverse to the
business, results of operations or financial condition of Viacom and its
subsidiaries taken as a whole, other than any change, effect or circumstance
relating to or resulting from (i) general changes in the media or
entertainment industries or the advertising markets, (ii) changes in general
economic conditions or securities markets in general or (iii) this Agreement
or the transactions contemplated hereby or the announcement thereof.

          SECTION 4.02. Certificate of Incorporation and By-Laws. Viacom has
made available to CBS a complete and correct copy of the Certificate of
Incorporation and the By-laws, each as amended to date, of Viacom and
Blockbuster Corporation ("Blockbuster"). The Certificates of Incorporation
and By-laws (or equivalent organizational documents) of Viacom and its
subsidiaries are in full force and effect. Except as would not have a Viacom
Material Adverse Effect, none of Viacom or its


<PAGE>


subsidiaries is in violation of any provision of its Certificate of
Incorporation or By-laws (or equivalent organizational documents).

          SECTION 4.03. Capitalization. The authorized capital stock of
Viacom consists of 500,000,000 shares of Viacom Class A Common Stock,
3,000,000,000 shares of Viacom Class B Common Stock and 200,000,000 shares
of Preferred Stock, par value $.01 per share, of Viacom ("Viacom Preferred
Stock"). As of September 3, 1999 (a) 139,923,921 shares of Viacom Class A
Common Stock and 605,085,135 shares of Viacom Class B Common Stock were
issued and outstanding, all of which were validly issued, fully paid and
nonassessable, (b) 1,356,400 shares of Viacom Class A Common Stock and
47,101,300 shares of Viacom B Common Stock were held in the treasury of
Viacom, (c) no shares of Viacom Class A Common Stock or Viacom Class B
Common Stock were held by subsidiaries of Viacom and (d) as of September 3,
1999, approximately 1,898,946 shares of Viacom Class B Common Stock were
reserved for future issuance pursuant to stock options or stock incentive
rights (collectively "Viacom Options") granted pursuant to Viacom's stock
option plans and arrangements (the "Viacom Stock Option Plans"). As of
September 3, 1999, no shares of Viacom Preferred Stock were issued and
outstanding. As of the date of this Agreement, except for the issuance of
Viacom Class B Common Stock pursuant to the exercise of Viacom Options and
options to purchase 11,600,000 shares of Class A Common Stock, par value
$.01 per share, of Blockbuster (the "Blockbuster Options") outstanding prior
to September 3, no shares of capital stock of Viacom or any of its
subsidiaries have been issued since September 3, 1999. Except as set forth
in this Section 4.03, as of the date of this Agreement, there are no
options, warrants or other rights, agreements (including registration rights
agreements), arrangements or commitments of any character relating to the
issued or unissued capital stock of Viacom or any of its subsidiaries or
obligating Viacom or any of its subsidiaries to issue or sell any shares of
capital stock of, or other equity interests in, Viacom or any of its
subsidiaries. All shares of capital stock of Viacom and its subsidiaries
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. As of the
date of this Agreement, there are no outstanding contractual material
obligations of Viacom or any subsidiary to repurchase, redeem or otherwise
acquire any shares of capital stock of Viacom or any of its subsidiaries or
to provide material funds to, or make any material investment (in the form
of a loan capital contribution or otherwise) in, any person. The Stockholder
(as defined in the Parent Voting Agreements) is the holder of a majority of
the issued and outstanding shares of Viacom Class A Common Stock.

          SECTION 4.04. Authority Relative to Agreement. Viacom has all
necessary power and authority to execute and deliver this Agreement, to
perform its obligations hereunder and to consummate the Merger and the other
transactions contemplated hereby. The execution and delivery of this
Agreement by Viacom and the consummation by Viacom of the Merger and the
other transactions contemplated hereby have been duly and validly authorized
by all necessary corporate action and no other corporate proceedings on the
part of Viacom are necessary to authorize the execution and delivery of this
Agreement or to consummate the Merger and the other transactions
contemplated hereby (other than, with respect to the Merger, the approval of
the Viacom Proposals by the holders of a majority of the then outstanding
shares of Viacom Class A Common Stock and the filing and recordation of
appropriate merger documents as required by Delaware Law and Pennsylvania
Law). This Agreement has been duly and validly executed and delivered by
Viacom and, assuming the due authorization,


<PAGE>


execution and delivery by CBS, this Agreement constitutes a legal, valid and
binding obligation of Viacom, enforceable against Viacom in accordance with its
terms.

          SECTION 4.05. No Conflict; Required Filings and Consents. (a) The
execution and delivery of this Agreement by Viacom does not, and the
performance of this Agreement by Viacom and the performance by Parent of the
Parent Voting Agreements will not, (i) conflict with or violate the
Certificate of Incorporation or Bylaws (or similar organization documents)
of (A) Viacom or Blockbuster or (B) any of its other subsidiaries, (ii)
assuming the consents, approvals and authorizations specified in Section
4.05(b) have been received and the waiting periods referred to therein have
expired, and any condition precedent to such consent, approval,
authorization, or waiver has been satisfied, conflict with or violate any
Law applicable to Viacom or any of its subsidiaries or by which any property
or asset of Viacom or any of its subsidiaries 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, 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 of its subsidiaries pursuant to, any note, bond,
mortgage, indenture or credit agreement, or, to Viacom's knowledge as of the
date of this Agreement, any other, contract, agreement, lease, license,
permit, franchise or other instrument or obligation to which Viacom or any
of its subsidiaries is a party or by which Viacom or any of its subsidiaries
or any property or asset of Viacom or any of its subsidiaries is bound or
affected, except, in the case of clauses (i)(B), (ii) and (iii), for any
such conflicts, violations, breaches, defaults or other occurrences of the
type referred to above which would not have a Viacom Material Adverse Effect
or would not prevent or materially delay the consummation of the Merger;
provided, however, that for purposes of this Section 4.05(a), the definition
of Viacom Material Adverse Effect shall be read so as not to include clause
(iii) of the definition thereof.

          (b) The execution and delivery of this Agreement by Viacom do not,
the performance of this Agreement by Viacom and the performance by Parent of
the Parent Voting Agreements will not, require any consent, approval,
authorization, waiver or permit of, or filing with or notification to, any
governmental or regulatory authority, domestic, foreign or supranational,
except for applicable requirements of the Exchange Act, the Securities Act,
Blue Sky Laws, the HSR Act, such filings, approvals and waivers as may be
required by the Communications Act, applicable requirements of the
Investment Canada Act of 1985 and the Competition Act (Canada), any other
non-United States competition, antitrust and investment law, filing and
recordation of appropriate merger documents as required by Delaware Law and
Pennsylvania Law and the rules of the NYSE and except where failure to
obtain such consents, approvals, authorizations or permits, or to make such
filings or notifications, would not have a Viacom Material Adverse Effect or

order, writ, judgment, injunction, decree, determination or award imposed by
any court, arbitration or Governmental Authority, in each case except as
would not have a Viacom Material Adverse Effect.

          SECTION 4.10. Employee Benefit Plans. (a) With respect to each
employee benefit plan, program, arrangement and contract (including, without
limitation, any "employee benefit plan", as defined in Section 3(3) of
ERISA), maintained or contributed to by Viacom or any of its subsidiaries,
or with respect to which Viacom or any of its subsidiaries could incur
liability under Section 4069 of ERISA, other than multiemployer plans within

agreements with the top five most highly compensated executive officers of
Viacom or any of its subsidiaries; (ii) copies of all material severance

or relating to its or its subsidiaries' employees; and (iii) copies of all
material plans, programs, agreements and other arrangements of Viacom or any

limitation, severance, unemployment compensation, "golden parachute" or
otherwise) becoming due to any director, officer or employee of Viacom or
any of its subsidiaries from Viacom or any of its affiliates under any
Viacom Benefit Plan or otherwise, which payment is material in relation to
the compensation previously provided to such individual (other than payments
resulting from a change in responsibilities or reporting obligations of
individual employees), (ii) materially increase any benefits otherwise
payable under any Viacom Benefit Plan, which increase is material in
relation to the benefits previously provided or (iii) result in any

currently available that the Viacom Benefit Plan is so qualified and each
trust established in connection with any Viacom Benefit Plan which is
intended to be exempt from federal income taxation under Section 501(a) of
the Code has received a determination letter from the IRS that it is so
exempt, and no fact or event has occurred since the date of such

adversely affect the qualified status of any such Viacom Benefit Plan or the
exempt status of any such trust.

          SECTION 4.11. Labor Matters. There is no labor dispute, strike or
work stoppage against Viacom or any of its subsidiaries pending or, to the
knowledge of Viacom, threatened which would reasonably be expected to
interfere with the respective business activities of Viacom or any of its
subsidiaries, except for such disputes, strikes or work stoppages which
would not have a Viacom Material Adverse Effect. There is no charge or
complaint against Viacom or any of its subsidiaries by the National Labor
Relations Board or any comparable state agency pending or threatened in
writing, except for such charges or complaints (or related unfair labor
practices) which would not have a Viacom Material Adverse Effect.

     sampling, monitoring, treatment, remediation, removal or cleanup of
     Hazardous Materials (as defined below) and, to the knowledge of Viacom,
     no investigation, litigation or other proceeding is pending or
     threatened in writing with respect thereto, or (ii) is an indemnitor in

     indemnitee for any liability under any Environmental Law or relating to
     any Hazardous Materials; and

          (d) none of the real property owned or leased by Viacom or any of
     its subsidiaries is listed or, to the knowledge of Viacom, proposed for
     listing on the "National Priorities List" under CERCLA, as updated

     requiring investigation or cleanup.

          SECTION 4.13. Trademarks, Patents and Copyrights. Except as would
not have a Viacom Material Adverse Effect, Viacom and its subsidiaries own,

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 its subsidiaries as currently
conducted, and no assertion or claim has been made in writing challenging
the validity of any of the foregoing which would have a Viacom Material
Adverse Effect. To the knowledge of Viacom, the conduct of the business of
Viacom and its 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,
except for such conflicts which would not have a Viacom Material Adverse
Effect.

          SECTION 4.14. Taxes. Except as would not have a Viacom Material
Adverse Effect, (a) each of Viacom and each of its subsidiaries has timely
filed all federal, state, local and foreign tax returns and reports

discharged all Taxes shown as due thereon and has paid all of such other
Taxes as are due, other than such payments as are being contested in good

Agreement.

          SECTION 4.15. Tax Matters. None of Viacom or any of its affiliates
has taken or agreed to take any action that would prevent the Merger from
constituting a transaction qualifying under Section 368(a) of the Code. None
of Viacom or any of its affiliates or agents is aware of any agreement, plan
or other circumstance that would prevent the Merger from qualifying under
Section 368(a) of the Code, that could prevent them from providing
representations required in Sections 7.02(c) or 7.03(c), or that could
prevent the opinions described in such Sections from being given and to the
knowledge of Viacom the Merger will so qualify.

          SECTION 4.16. Year 2000 Compliance. (a) Viacom has adopted a plan
that it believes will cause Viacom Systems (as defined below) to be Viacom
Year 2000 Compliant (as defined below) (such plan, as it may be amended,

Plan") in all material respects. Viacom has taken, and between the date of
this Agreement and the Effective Time will continue to take, all reasonable
steps to implement the Viacom Year 2000 Plan with respect to the Viacom
Systems. Notwithstanding anything in this Section 4.16 to the contrary,
Viacom does not represent or warrant that Viacom Systems (or any other
operations, systems, equipment or software of Viacom or its subsidiaries or
any of their respective affiliates) are or will be Viacom Year 2000
Compliant at or prior to the Effective Time, regardless of whether the
Viacom Year 2000 Plan has or has not been implemented or complied with.

          (b) For purposes of this Section 4.16, (i) "Viacom Systems" shall
mean all computer, hardware, software, systems, and equipment (including

required to operate the current products of Viacom and its subsidiaries,
and/or material to or necessary for Viacom and its subsidiaries to carry on
their respective businesses as currently conducted; and (ii) "Viacom Year
2000 Compliant" means that Viacom Systems will (A) manage, accept, process,
store and output data involving dates reasonably expected to be encountered
in the foreseeable future and (B) accurately process date data from, into
and between the 20th and 21st centuries and each date during the years 1999

that, as of the date of such opinion, the Exchange Ratio is fair to the
stockholders of Viacom, from a financial point of view, and Viacom will
deliver a copy of such opinion to CBS promptly after the date of this

vote of the holders of any class or series of capital stock of Viacom
necessary to approve the transactions contemplated by this Agreement.


<PAGE>


          SECTION 4.19. Section 203 of Delaware Law. The Board of Directors
of Viacom has approved this Agreement and such Viacom approval is sufficient
to render inapplicable to this Agreement, the Parent Voting Agreements and
the transactions contemplated hereby and thereby the provisions of Section
203 of Delaware Law.

          SECTION 4.20. Brokers. No broker, finder or investment banker
(other than the Viacom Financial Advisor) is entitled to any brokerage,
finder's or other fee or commission in connection with the Merger based upon
arrangements made by or on behalf of Viacom.

the Board of Directors of Viacom to the stockholders of Viacom in favor of
approval of the Viacom Proposals; provided, however, that the Board of
Directors of Viacom may take or disclose to its stockholders a position

disclosure required under applicable Law and may, prior to the date of its
Stockholders' Meeting, withdraw, modify, or change any such recommendation
to the extent that the Board of Directors of Viacom determines in good faith
that such withdrawal, modification or change is required in order to comply

Stockholders Meeting in accordance with the time period specified in Section
6.02.

          (d) No amendment or supplement to the Proxy Statement or the
Registration Statement will be made by Viacom or CBS without the approval of
the other party, which shall not be unreasonably withheld or delayed. Each
of Viacom and CBS will advise the other, promptly after it receives notice
thereof, of the time when the Registration Statement has become effective or
any supplement or amendment has been filed, the issuance of any stop order,
the suspension of the qualification of the Viacom Class B Common Stock
issuable in connection with the Merger for offering or sale in any
jurisdiction, or any request by the SEC for amendment of the Proxy Statement
or the Registration Statement or comments thereon and responses thereto or
requests by the SEC for additional information.

          (e) The information supplied by CBS for inclusion in the
Registration Statement and the Proxy Statement (including by incorporation
by reference) shall not, at (i) the time the Registration Statement is
declared effective, (ii) the time the Proxy

its subsidiaries, or their respective officers or directors, should be
discovered by CBS which, pursuant to the Securities Act or Exchange Act,
should be set forth in an amendment or a supplement to the Registration
Statement or Proxy Statement, CBS shall promptly inform Viacom. All
documents that CBS is responsible for filing with the SEC in connection with
the Merger will comply as to form in all material respects with the

or directors, should be discovered by Viacom which, pursuant to the
Securities Act or Exchange Act, should be set forth in an amendment or a
supplement to the Registration Statement or Proxy Statement, Viacom shall
promptly inform CBS. All documents that Viacom is responsible for filing
with the SEC in connection with the Merger will comply as to form in all
material respects with the applicable requirements of the Securities Act and
the Exchange Act.

          (g) Viacom and CBS each hereby (i) consents to the use of its name
and, on behalf of its subsidiaries and affiliates, the names of such
subsidiaries and affiliates and to the inclusion of financial statements and
business information relating to such party and its subsidiaries and
affiliates (in each case, to the extent required by applicable securities
laws) in any registration statement or proxy statement prepared by Viacom,
CBS or any person or entity with which Viacom or CBS, consistent with their
obligations under this Agreement, has entered into, or may prior to the
Effective Time enter into, a definitive acquisition agreement, (ii) agrees
to use its reasonable best efforts to obtain the written consent of any
person or entity retained by it which may be required to be named (as an
expert or otherwise) in such registration statement or proxy statement;
provided, that such party shall not be required to make any material payment
to such person or entity in connection with such party's efforts to obtain
any such consent, and (iii) agrees to cooperate, and agrees to use its
reasonable best efforts to cause its subsidiaries and affiliates to
cooperate, with any legal counsel, investment banker, accountant or other
agent or representative retained by any of the parties specified in clause

as determined after consultation with each party's counsel, to be disclosed
by applicable securities laws in any such registration statement or proxy
statement.

          (h) CBS and Viacom will use their best efforts to complete the pro
forma financial statements with respect to the Merger, in a form suitable
for filing in connection


<PAGE>


with a registration statement under the Securities Act, as soon as possible, and
in any event within 10 days after the execution of this Agreement.

          (i) CBS shall consult with Viacom, and provide Viacom reasonable
opportunity to review and comment on, and CBS and Viacom will use their
respective reasonable best efforts to agree on, CBS's and Infinity's
accounting for the Pending Transactions.

          SECTION 6.02. Stockholders' Meetings. Each of Viacom and CBS shall
call and hold a meeting of its stockholders or shareholders, respectively
(collectively, the "Stockholders' Meetings"), as promptly as practicable for
the purpose of voting upon, in the case of Viacom, the Viacom Proposals,
and, in the case of CBS, the adoption of this Agreement, and CBS and Viacom
shall hold the Stockholders' Meeting as soon as practicable after the date
on which the Registration Statement becomes effective and will use
reasonable best efforts to hold the Stockholders' Meetings on the same day.
Each of Viacom and CBS shall use its reasonable best efforts to solicit from
its stockholders proxies in favor of the adoption of this Agreement, in the
case of CBS, and the Viacom Proposals, in the case of Viacom, and shall take
all other action necessary or advisable to secure the vote of its
stockholders and shareholders, respectively, required by the NYSE,
Pennsylvania Law or Delaware Law, as applicable, to obtain such approvals;
provided, however, that Viacom or CBS, as applicable, shall not be obligated
to solicit proxies in favor of the adoption of this Agreement, in the case
of CBS, or in favor of the Viacom Proposals, in the case of Viacom, at its
Stockholders' Meeting to the extent that the Board of Directors of Viacom or
CBS, as applicable, determines in good faith that such failure to solicit
proxies is required in order to comply with its fiduciary duties under
applicable Law after receiving advice to such effect from independent legal
counsel (who may be such party's regularly engaged outside legal counsel);
provided, further, however, that notwithstanding anything to the contrary in
the foregoing, each of CBS and Viacom shall hold its Stockholders Meeting in
accordance with the time periods specified in the first sentence of this
Section 6.02.

          SECTION 6.03. Appropriate Action; Consents; Filings. (a) Each of
the parties hereto shall (i) make promptly its respective filings, and
thereafter make any other required submissions under the HSR Act with
respect to the transactions contemplated herein and (ii) make promptly
filings with or applications to the FCC with respect to the transactions
contemplated herein. The parties hereto will use their respective best
efforts, and will take all actions necessary, to consummate and make
effective the transactions contemplated herein and to cause the conditions
to the Merger set forth in Article VII to be satisfied, (including using
best efforts, and taking all actions necessary, to obtain all licenses,
permits, consents, approvals, authorizations, waivers, qualifications and
orders of Governmental Authorities as are necessary for the consummation of
the transactions contemplated herein), and will do so in a manner designed
to obtain such regulatory clearance and the satisfaction of such conditions
as expeditiously as possible.

          (b) CBS and Viacom each agree to take promptly any and all steps
necessary to avoid or eliminate each and every impediment and obtain all
consents or waivers under any antitrust, competition or communications or
broadcast Law that may be asserted by any U.S. federal, state and local and
non-United States antitrust or competition authority, or by the FCC or
similar authority, so as to enable the parties to close the transactions
contemplated by this Agreement as expeditiously as possible, including
committing to or effecting, by consent decree, hold separate orders, trust,
or


<PAGE>


otherwise, the sale or disposition of such of its assets or businesses as
are required to be divested in order to obtain the consent of the FCC to or
avoid the entry of, or to effect the dissolution of, any decree, order,
judgment, injunction, temporary restraining order or other order in any suit
or proceeding, that would otherwise have the effect of preventing or
materially delaying the consummation of the Merger and the other
transactions contemplated by this Agreement. In addition, each of CBS and
Viacom agree to take promptly any and all steps necessary to obtain any
consent or to vacate or lift any order, writ, judgment, injunction, decree,
stipulation, determination or award entered by or with any Governmental
Authority (each, an "Order") relating to antitrust or communications or
broadcast matters that would have the effect of making any of the
transactions contemplated by this Agreement illegal or otherwise prohibiting
or materially delaying their consummation. The parties will expeditiously
agree on a complete plan for compliance with applicable FCC ownership
requirements for inclusion in the FCC filings and will expeditiously make
such filings (including such agreed plan) with the FCC following the date of
this Agreement.

          (c) Each of Viacom and CBS shall give (or shall cause its
respective subsidiaries to give) any notices to third parties, and Viacom
and CBS shall use, and cause each of its subsidiaries to use, its reasonable
best efforts to obtain any third party consents, necessary, proper or
advisable to consummate the Merger. Each of the parties hereto will furnish
to the other such necessary information and reasonable assistance as the
other may request in connection with the preparation of any required
governmental filings or submissions and will cooperate in responding to any
inquiry from a Governmental Authority, including immediately informing the
other party of such inquiry, consulting in advance before making any
presentations or submissions to a Governmental Authority, and supplying each
other with copies of all material correspondence, filings or communications
between either party and any Governmental Authority with respect to this
Agreement.

          SECTION 6.04. Access to Information; Confidentiality. (a) From the
date hereof to the Effective Time, to the extent permitted by applicable Law
and contracts, Viacom will provide to CBS (and its officers, directors,
employees, accountants, consultants, legal counsel, agents and other
representatives, collectively, "Representatives") access to all information
and documents which CBS may reasonably request regarding the business,
assets, liabilities, employees and other aspects of Viacom.

          (b) From the date hereof to the Effective Time, to the extent
permitted by applicable Law and contracts, CBS will provide to Viacom and
its Representatives access to all information and documents which Viacom may
reasonably request regarding the business, assets, liabilities, employees
and other aspects of CBS.

          (c) The parties shall comply with, and shall cause their
respective Representatives to comply with all of their respective
obligations under the Confidentiality Agreement dated August 27, 1999 (the
"Confidentiality Agreement") between CBS and Viacom.

          (d) No investigation pursuant to this Section 6.04 shall affect
any representation or warranty in this Agreement of any party hereto or any
condition to the obligations of the parties hereto.

          SECTION 6.05. No Solicitation of Competing Transactions. (a) CBS
shall not, directly or indirectly, through any officer, director, agent or
otherwise, initiate, solicit or knowingly encourage (including by way of
furnishing non-public information), or take any other action knowingly to
facilitate, any inquiries or the making of any proposal that constitutes, or
may reasonably be expected to lead to, any Competing Transaction (as defined
below), or enter into or maintain or continue discussions or negotiate with
any person or entity in furtherance of such inquiries or to obtain a
Competing Transaction, or agree to or endorse any Competing Transaction, or
authorize any of the officers, directors or employees of CBS or any
investment banker, financial advisor, attorney, accountant or other agent or

as promptly as practicable of all of the relevant material details relating
to all inquiries and proposals which CBS or any such officer, director,
employee, investment banker, financial advisor, attorney, accountant or
other agent or representative may receive relating to any of such matters,
provided, however, that prior to the adoption of this Agreement by the
shareholders of CBS, nothing contained in this Section 6.05 shall prohibit
the Board of Directors of CBS from (i) furnishing information to, or
entering into and engaging in discussions or negotiations with, any person
that makes a bona fide unsolicited written proposal that the Board of
Directors of CBS determines in good faith, after consultation with CBS's
financial advisors and independent legal counsel, can be reasonably expected
to result in a CBS Superior Proposal; provided, that prior to furnishing
such information to, or entering into discussions or negotiations with, such
person, CBS (1) provides notice to Viacom to the effect that it is
furnishing information to, or entering into discussions or negotiations
with, such person and provides in any such notice to Viacom in reasonable
detail the identity of the person making such proposal and the material
terms and conditions of such proposal, (2) provides Viacom with all
information regarding CBS provided or to be provided to such person which
Viacom has not previously been provided, and provided, further that CBS
shall keep Viacom informed, on a prompt basis, of the status and material
terms of any such proposal and the status of any such discussions and
negotiations and (3) receives from such person or entity an executed
confidentiality agreement containing customary terms (which need not contain
"standstill" or similar provisions), (ii) complying with Rule 14e-2
promulgated under the Exchange Act with regard to a tender or exchange offer
or making any disclosure required under applicable Law or (iii) failing to
make or withdrawing or modifying its recommendation referred to in Section
6.01 following the making of a CBS Superior Proposal if, solely in the case
of this clause (iii), the Board of Directors of CBS, after consultation with
and based upon the advice of independent legal counsel, determines in good
faith that such action is necessary for the Board of Directors of CBS to
comply with its fiduciary duties under applicable law.

          (b) For purposes of this Agreement, "Competing Transaction" shall
mean any of the following involving CBS: (i) any merger, consolidation,
share exchange, business combination, issuance or purchase of securities or
other similar transaction other than transactions specifically permitted
pursuant to Section 5.01 of this Agreement; (ii) any sale, lease, exchange,
mortgage, pledge, transfer or other disposition of the assets of CBS in a
single transaction or series of related transactions; (iii) any tender offer
or exchange offer for CBS securities or the filing of a registration
statement under the Securities Act in connection with any such exchange
offer; in the case of clauses (i), (ii) or (iii) above, which transaction
would result in a third party (or its shareholders) acquiring more than 35%
of the voting power of the Shares then outstanding or more than 35% of the
assets of CBS and its subsidiaries, taken as a whole; or (iv) any public


<PAGE>


announcement of an agreement, proposal, plan or intention to do any of the
foregoing, either during the effectiveness of this Agreement or at any time
thereafter.

          (c) For purposes of this Agreement, a "CBS Superior Proposal"
means any proposal made by a third party which would result in such party
(or in the case of a parent-to-parent merger, its stockholders) acquiring,
directly or indirectly, including pursuant to a tender offer, exchange
offer, merger, consolidation, share exchange, business combination, share
purchase, asset purchase, recapitalization, liquidation, dissolution, joint
venture or similar transaction, more than 50% of the voting power of the
Shares then outstanding or all or substantially all the assets of CBS and
its subsidiaries, taken as a whole, for consideration which the Board of

employees under CBS's medical and dental plans during the calendar year in
which the Effective Time occurs. In addition, service with CBS shall be
recognized for all purposes under Viacom's compensation and benefit plans,

          Stock.

          A. Voting Rights and Powers. Except as otherwise provided in this
     Restated Certificate of Incorporation or required by law, with respect to

     combined in the same manner and on the same basis as the outstanding
     shares of the other class of Common Stock have been split, subdivided or
     combined.

     Stock outstanding, each record holder of shares of Class A Common Stock

     equal number of shares of Class B Common Stock by surrendering the
     certificates for such shares, accompanied by payment of documentary,
     stamp or similar issue or transfer taxes, if any, along with a written
     notice by such record holder to the Corporation stating that such record
     holder desires to convert such shares into the same number of shares of
     Class B Common Stock and requesting that the Corporation issue all of
     such Class B Common Stock to the persons named therein, setting forth the
     number of shares of Class B Common Stock to be issued to each such person

     (1) Power of the Board of Directors. Subject to Article XIII of this

Certificate of Incorporation:

          (a) To make, alter, amend or repeal the By-Laws of the Corporation;

     adopted;

          (b) To determine the rights, powers, duties, rules and procedures
     that affect the power of the Board of Directors to manage and direct the

                                  ARTICLE VI

                         INDEMNIFICATION OF DIRECTORS,
                              OFFICERS AND OTHERS

     (1) Action Not By or on Behalf of Corporation. The Corporation shall
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative (other than an action by or
in the right of the Corporation) by reason of the fact that he is or was a
Director, officer, employee or agent of the Corporation, or is or was serving
at the request of the Corporation as a director, officer, employee or agent
(including, without limitation, a trustee) of another corporation,
partnership, joint venture, trust or other enterprise, against judgments,
fines, amounts paid in settlement and expenses (including, without limitation,
attorneys' fees), actually and reasonably incurred by him in connection with
such action, suit or proceeding if he acted in good faith and in a manner
reasonably believed to be in or not opposed to the best interests of the
Corporation, and with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The termination of any
action, suit or proceeding by judgment, order, settlement, conviction, or upon
a plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was unlawful.

     (2) Action By or on Behalf of Corporation. The Corporation shall
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action or suit by or in the right of
the Corporation to procure a judgment in its favor by reason of the fact that
he is or was a Director, officer, employee or agent of the Corporation, or is
or was serving at the request of the Corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust,
or other enterprise against expenses (including, without limitation,
attorneys' fees) actually and reasonably incurred by him in connection with
the defense or settlement of such action or suit if he acted in good faith and
in a manner he reasonably believed to be in or not opposed to the best
interests of the Corporation, except that no indemnification shall be made in
respect of any claim, issue or matter as to which such person shall have been
adjudged to be liable to the Corporation unless and only to the

                                       6

<PAGE>



extent that the court in which such action or suit was brought shall determine
upon application that, despite the adjudication of liability and in view of
all of the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the court shall deem proper.

     (3) Successful Defense. To the extent that a present or former Director,
officer, employee or agent of the Corporation has been successful on the
merits or otherwise in defense of any action, suit or proceeding referred to
in Section 1 or 2 of this Article VI, or in defense of any claim, issue or
matter therein, he shall be indemnified against expenses (including, without
limitation, attorneys' fees) actually and reasonably incurred by him in
connection therewith.

     (4) Determination of Right to Indemnification in Certain Circumstances.
Any indemnification under Section 1 or 2 of this Article VI (unless ordered by
a court) shall be made by the Corporation only as authorized in the specific
case upon a determination that indemnification of the present or former
Director, officer, employee or agent is proper in the circumstances because he
has met the applicable standard of conduct set forth in Section 1 or 2 of this
Article IV. Such determination shall be made, with respect to a person who is
a Director or officer at the time of such determination, (1) by a majority
vote of the Directors who are not parties to such action, suit or proceeding,
even though less than a quorum, or (2) by a committee of such Directors
designated by a majority vote of such Directors, even though less than a
quorum, or (3) if there are no such Directors, or if such Directors so direct,
by independent legal counsel in a written opinion, or (4) by the stockholders
of the Corporation entitled to vote thereon.

     (5) Advance Payment of Expenses.

     (a) Expenses (including attorneys' fees) incurred by a Director or
officer in defending any civil, criminal, administrative or investigative
action, suit or proceeding shall be paid by the Corporation in advance of the
final disposition of such action, suit or proceeding upon receipt of an
undertaking by or on behalf of such Director or officer, to repay such amount
if it shall ultimately be determined that he is not entitled to be indemnified
by the Corporation as authorized in this Article.

     (b) Expenses (including attorneys' fees) incurred by any other employee
or agent in defending any civil, criminal, administrative or investigative
action, suit or

                                       7

<PAGE>



proceeding may be paid by the Corporation in advance of the final disposition
of such action, suit or proceeding upon such terms and conditions, if any, as
the Corporation deems appropriate.

     (6) Not Exclusive. The indemnification and advancement of expenses
provided by, or granted pursuant to, the other sections of this Article VI
shall not be deemed exclusive of any other rights to which a person seeking
indemnification or advancement of expenses may be entitled under any statute,
by-law, agreement, vote of stockholders or disinterested Directors or
otherwise, both as to action in his official capacity and as to action in
another capacity while holding such office. Without limiting the foregoing,
the Corporation is authorized to enter into an agreement with any Director,
officer, employee or agent of the Corporation providing indemnification for
such person against expenses, including, without limitation, attorneys' fees,
judgments, fines and amounts paid in settlement that result from any
threatened, pending or completed action, suit, or proceeding, whether civil,
criminal, administrative or investigative, including, without limitation, any
action by or in the right of the Corporation, that arises by reason of the
fact that such person is or was a Director, officer, employee or agent of the
Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, to the full extent allowed by law,
except that no such agreement shall provide for indemnification for any
actions that constitute fraud, actual dishonesty or willful misconduct.

     (7) Insurance. The Corporation may purchase and maintain insurance on
behalf of any person who is or was a Director, officer, employee or agent of
the Corporation, or is or was serving as the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise against any liability asserted
against him and incurred by him in any such capacity, or arising out of his
status as such, whether or not the Corporation would have the power to
indemnify him against such liability under the provisions of this Article VI.

     (8) Certain Definitions. For the purposes of this Article VI, (A) any
Director, officer, employee or agent of the Corporation who shall serve as a

<PAGE>



(B) any director, officer, employee or agent of any subsidiary corporation,
joint venture, trust or other enterprise wholly owned by the Corporation,
shall be deemed to be serving as such director, officer, employee or agent at
the request of the Corporation, unless the Board of Directors of the
Corporation shall determine otherwise. In all other instances where any person
shall serve as a director, officer, employee or agent of another corporation,
joint venture, trust or other enterprise of which the Corporation is or was a
stockholder or creditor, or in which it is or was otherwise interested, if it
is not otherwise established that such person is or was serving as such
director, officer, employee or agent at the request of the Corporation, the
Board of Directors of the Corporation may determine whether such service is or
was at the request of the Corporation, and it shall not be necessary to show
any actual or prior request for such service. For purposes of this Article VI,
references to a corporation include all constituent corporations absorbed in a
consolidation or merger as well as the resulting or surviving corporation so
that any person who is or was a director, officer, employee or agent of such a
constituent corporation or is or was serving at the request of such
constituent corporation as a director, officer, employee or agent of another
corporation, joint venture, trust or other enterprise shall stand in the same
position under the provisions of this Article VI with respect to the resulting
or surviving corporation as he would if he had served the resulting or
surviving corporation in the same capacity. For purposes of this Article VI,
references to "other enterprises" shall include employee benefit plans;
references to "fines" shall include any excise taxes assessed on a person with
respect to an employee benefit plan; and references to "serving at the request
of the Corporation" shall include any service as a director, officer, employee
or agent of the Corporation which imposes duties on, or involves services by,
such director, officer, employee, or agent with respect to an employee benefit
plan, its participants, or beneficiaries, and a person who acted in good faith
and in a manner he reasonably believed to be in the interest of the
participants and beneficiaries of an employee benefit plan shall be deemed to
have acted in a manner "not opposed to the best interests of the Corporation"
as referred to in this Article VI.

     (9) The indemnification and advancement of expenses provided by, or
granted pursuant to, this Article VI shall, unless otherwise provided when
authorized or ratified, continue as to a person who has ceased to be a
director, officer, employee or agent and shall inure to the benefit of the
heirs, executors and administrators of such a person.

     (a) A Director's liability to the Corporation for breach of duty to the
Corporation or its stockholders shall be limited to the fullest extent
permitted by Delaware law as now in effect or hereafter amended. In particular
no Director of the Corporation shall be liable to the Corporation or any of
its stockholders for monetary damages for breach of fiduciary duty as a
director, except for liability (i) for any breach of the Director's duty of
loyalty to the Corporation or its stockholders, (ii) for acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation
of law, (iii) under Section 174 of the Delaware General Corporation Law, as
the same exists or hereafter may be amended, or (iv) for any transaction from
which the Director derived an improper personal benefit.

     (b) Any repeal or modification of the foregoing paragraph (a) by the
stockholders of the Corporation entitled to vote thereon shall not adversely
affect any right or protection of a director of the Corporation existing at
the time of such repeal or modification.

     (c) If the General Corporation Law of the State of Delaware is amended to
authorize corporate action further eliminating or limiting the liability of
directors, then a director of the Corporation, in addition to the
circumstances in which he is not now liable, shall be free of liability to the
fullest extent permitted by the General Corporation Law of the State of
Delaware, as so amended.

                                 ARTICLE VIII

                         RESERVATION OF RIGHT TO AMEND
                         CERTIFICATE OF INCORPORATION

     Subject to Article XIII of this Restated Certificate of Incorporation,
the Corporation reserves the right to amend, alter, change or repeal any
provision contained in this Restated Certificate of Incorporation in the
manner now or hereafter prescribed by law, and all the provisions of this
Restated Certificate of Incorporation and all rights and powers conferred in
this Restated Certificate of Incorporation on stockholders, directors and
officers are subject to this reserved power.

     Each reference in the Restated Certificate of Incorporation to "the
Restated Certificate of Incorporation", "hereunder",

                                      10

<PAGE>



"hereof", or words of like import and each reference to the Restated
Certificate of Incorporation set forth in any amendment to the Restated
Certificate of Incorporation shall mean and be a reference to the Restated
Certificate of Incorporation as supplemented and amended through such
amendment to the Restated Certificate of Incorporation.

                                  ARTICLE IX

                                 VOTING RIGHTS

     (1) Class A Common Stock. In addition to any other approval required by
law or by this Restated Certificate of Incorporation, the affirmative vote of
a majority of the then outstanding shares of Class A Common Stock, voted
separately as a class, shall be necessary to approve any consolidation of the
Corporation with another corporation, any merger of the Corporation into
another corporation or any merger of any other corporation into the
Corporation pursuant to which shares of Common Stock are converted into or
exchanged for any securities or any other consideration.

     (2) Preferred Stock. Subject to Article XIII of this Restated Certificate
of Incorporation, in addition to any other approval required by law or by this
Restated Certificate of Incorporation, each particular series of any class of
Preferred Stock shall have such right to vote, if any, as shall be fixed in
the resolution or resolutions, adopted by the Board of Directors, providing
for the issuance of shares of such particular series.

                                   ARTICLE X

                                STOCK OWNERSHIP
                      AND THE FEDERAL COMMUNICATIONS LAWS

     (1) Requests for Information. So long as the Corporation or any of its
subsidiaries holds any authorization from the Federal Communications
Commission (or any successor thereto), if the Corporation has reason to
believe that the ownership, or proposed ownership, of shares of capital stock
of the Corporation by any stockholder or any person presenting any shares of
capital stock of the Corporation for transfer into his name (a "Proposed
Transferee") may be inconsistent with, or in violation of, any provision of
the Federal Communications Laws (as hereinafter defined), such stockholder or
Proposed Transferee, upon request of the Corporation, shall furnish promptly
to the Corporation such information (including, without limitation,
information with respect to citizenship, other ownership interests and
affiliations) as the Corporation shall reasonably request to determine whether

                                      11

<PAGE>



the ownership of, or the exercise of any rights with respect to, shares of
capital stock of the Corporation by such stockholder or Proposed Transferee is
inconsistent with, or in violation of, the Federal Communications Laws. For
purposes of this Article X, the term "Federal Communications Laws" shall mean
any law of the United States now or hereafter in effect (and any regulation
thereunder) pertaining to the ownership of, or the exercise of the rights of
ownership with respect to, capital stock of corporations holding, directly or
indirectly, Federal Communications Commissions authorizations, including,
without limitation, the Communications Act of 1934, as amended (the
"Communications Act"), and regulations thereunder pertaining to the ownership,
or the exercise of the rights of ownership, of capital stock of corporations
holding, directly or indirectly, Federal Communications Commission
authorizations, by (i) aliens, as defined in or under the Communications Act,
as it may be amended from time to time, (ii) persons and entities having
interests in television or radio stations, daily newspapers and cable
television systems or (iii) persons or entities, unilaterally or otherwise,
seeking direct or indirect control of the Corporation, as construed under the
Communications Act, without having obtained any requisite prior Federal
regulatory approval to such control.

     (2) Denial of Rights, Refusal to Transfer. If any stockholder or Proposed
Transferee from whom information is requested should fail to respond to such
request pursuant to Section (1) of this Article or the Corporation shall
conclude that the ownership of, or the exercise of any rights of ownership
with respect to, shares of capital stock of the Corporation, by such
stockholder or Proposed Transferee, could result in any inconsistency with, or
violation of, the Federal Communications Laws, the Corporation may refuse to
permit the transfer of shares of capital stock of the Corporation to such
Proposed Transferee, or may suspend those rights of stock ownership the
exercise of which would result in any inconsistency with, or violation of, the
Federal Communications Laws, such refusal of transfer or suspension to remain
in effect until the requested information has been received and the
Corporation has determined that such transfer, or the exercise of such
suspended rights, as the case may be, is permissible under the Federal
Communications Laws, and the Corporation may exercise any and all appropriate
remedies, at law or in equity, in any court of competent jurisdiction, against
any such stockholder or Proposed Transferee, with a view towards obtaining
such information or preventing or curing any situation which would cause any
inconsistency with, or violation of, any provision of the Federal
Communications Laws.

     (3) Legends. The Corporation may note on the certificates of its capital
stock that the shares represented by such certificates are subject to the
restrictions set forth in this Article.

     (4) Certain Definitions. For purposes of this Article, the word "person"
shall include not only natural persons but partnerships, associations,
corporations, joint ventures and other entities, and the word "regulation"
shall include not only regulations but rules, published policies and published
controlling interpretations by an administrative agency or body empowered to
administer a statutory provision of the Federal Communications Laws.

                                  ARTICLE XI

                   TRANSACTIONS WITH DIRECTORS AND OFFICERS

     No contract or transaction between the Corporation and one or more of its
directors or officers, or between the Corporation and any other corporation,
partnership, association, or other organization in which one or more of its
directors or officers are directors or officers, or have a financial interest,
shall be void or voidable solely for this reason, or solely because the
director or officer is present at or participates in the meeting of the board
or committee thereof which authorizes the contract or transaction, or solely
because his or their votes are counted for such purpose if (a) the material
facts as to his relationship or interest and as to the contract or transaction
are disclosed or are known to the Board of Directors or the committee, and the
Board of Directors or the committee in good faith authorizes the contract or
transaction by the affirmative votes of a majority of the disinterested
directors, even though the disinterested directors be less than a quorum, or
(b) the material facts as to his relationship or interest and as to the
contract or transaction are disclosed or are known to the stockholders
entitled to vote thereon, and the contract or transaction is specifically
approved in good faith by vote of such stockholders, or (c) the contract or
transaction is fair as to the Corporation as of the time it is authorized,
approved or ratified by the Board of Directors, a committee thereof, or the
stockholders entitled to vote thereon. Common or interested directors may be
counted in determining the presence of a quorum at a meeting of the Board of
Directors or of a committee which authorizes the contract or transaction.

     Whenever a compromise or arrangement is proposed between this Corporation

Corporation or of any creditor or stockholder thereof or on the application of

of Section 291 of Title 8 of the Delaware Code or on the application of
trustees in dissolution or of any receiver or receivers appointed for this

Code order a meeting of the creditors or class of creditors, and/or of the
stockholders or class of stockholders of this Corporation, as the case may be,
to be summoned in such manner as the said court directs. If a majority in
number representing three-fourths in value of the creditors or class of
creditors, and/or of the stockholders or class of stockholders of this
Corporation, as the case may be, agrees to any compromise or arrangement and
to any reorganization of the Corporation as a consequence of such compromise
or arrangement, the said compromise or arrangement and the said reorganization
shall, if sanctioned by the court to which the said application has been made,
be binding on all the creditors or class of creditors, and/or on all the
stockholders or class of stockholders, of this Corporation, as the case may
be, and also on this Corporation.

VIACOM                                                                     CBS

          VIACOM AND CBS TO MERGE IN LARGEST MEDIA TRANSACTION EVER

               $80 Billion Merger Creates the World's Premier
                       Entertainment and Media Company


New York, New York, September 7,1999 - Viacom Inc. (NYSE: VIA and VIAB) and
CBS Corporation (NYSE: CBS) today announced that their respective boards of
directors have unanimously approved a definitive agreement to merge the two
companies in the largest media transaction ever. The merger was announced by
Sumner Redstone, Chairman and Chief Executive Officer, Viacom Inc., and Mel
Karmazin, President and Chief Executive Officer, CBS Corporation.

The new company, which will be called Viacom, will be led by Sumner
Redstone, who will remain Chairman and CEO of Viacom. Mel Karmazin will
become President and Chief Operating Officer. All operations of the combined
company will report to Mr. Karmazin.

The new Viacom will be the world's leading company in the production,
promotion and distribution of entertainment, news, sports and music with
unmatched content and a portfolio of the world's most powerful brands.
Extraordinary assets in broadcast and cable television, a pre-eminent motion
picture studio, the leading radio and outdoor media company and a growing
portfolio of Internet ventures will create the largest seller of advertising
across the media landscape. The merger should also serve the public interest
by helping to sustain the continued vitality of free and universal
broadcasting.

Mr. Redstone said: "This exciting merger creates the industry-leading media
company for today and a dynamic growth vehicle that will benefit
shareholders well into the future. Our union will be king  not just in
content, but in its distribution, marketing, and packaging. We will be
global leaders in every facet of the media and entertainment industry,
financially strong from day one, with an enviable stable of global brands.
With Viacom and CBS performing at the top of their games, the timing for
this could not be better. Mel Karmazin is an excellent manager and a gifted
leader who shares my focus on building value for shareholders. Together,
with all the employees of Viacom and CBS, we will create an even brighter
future. Indeed, the creation of this formidable media giant marks the
beginning of a new era of explosive growth domestically and around the
world."

Mr. Karmazin said: "The new Viacom will be the first 21st Century media
company, with strong brands that lead the industry in all aspects of our
operations, a wealth of world-class content in film, television, radio,
publishing and the Internet, and the best distribution system in the
business in both the established and new media. It has been noted before
that the fit between our two companies is extraordinary. Each of us brings
unique and complementary strengths to the business mix, and opportunities
for creative synergy and revenue generation are many and exciting. I look
forward to working with Sumner and the great teams of people at both CBS and
Viacom to build this new enterprise into all it is capable of being, for the
benefit of our


<PAGE>


shareholders, advertisers, audiences and employees. The future is virtually
unlimited for this new and exciting company."

Under the terms of the agreement, CBS shareholders will receive for each
share of CBS 1.085 shares of Viacom Class B shares, which at the September
3, 1999 closing price of $45.06 per Viacom Class B share, is valued at
$48.89 per CBS share. This transaction, which has an enterprise value of $80
billion, will be tax free for shareholders of CBS and Viacom. On a pro forma
basis, the new Viacom would have generated approximately $21 billion in 1998
revenues and approximately $4.0 billion in EBITDA. Mr. Redstone remains
majority shareholder of Viacom's Class A voting shares and will continue to
control the company.

The union of the two companies offers a dramatic opportunity to drive
revenues and enhance shareholder value. Reaching the greatest number of
viewers and listeners of any media enterprise, spanning all ages and
demographics, the new Viacom will be the premier outlet for advertisers in
the world. Content will be driven and promoted across virtually all media
segments, including broadcast and cable television, radio and outdoor
advertising, and new media. The company will also be a pivotal player in the
world of music. Through its Infinity Radio stations and the branded
promotional power of MTV, MTV2, VH1, CMT, TNN and over the Internet, Viacom
will reach more music fans than any other entity worldwide. The scale of the
enterprise will also enable the company to acquire programming more
efficiently and maximize the effectiveness of its sales force.

Subject to actions taken to obtain regulatory clearances, the merged company
will include:

     *    Industry-leading cable networks, each uniquely powerful in its own
          target demographic, including MTV, Nickelodeon, VH1, TNN, CMT,
          MTV2, TV Land, Home Team Sports and Midwest Sports Channel; pay
          channels Showtime, The Movie Channel and FLIX, and interests in
          Comedy Central, Noggin and Sundance Channel, and significant cable
          programming operations worldwide;

          INF), the premier radio and outdoor media company in the world;

          markets and 18 of the top 20 markets in the nation; with the
          potential for strong TV duopolies in Philadelphia, Boston, Dallas
          and other top U.S. markets;

     *    Paramount Pictures, a leader in theatrical motion pictures since
          1912, with more than 2,500 titles in its library, including such
          Oscar winners as Forrest Gump, Braveheart and Titanic (the highest
          grossing motion picture of all time);

     *    Preeminent production and syndication operations, with CBS
          Productions, Paramount Television, Eyemark Entertainment, Viacom

          Productions, Inc., among others, all contributing content, sales
          and distribution capability;

     *    Simon & Schuster, a leading consumer book publisher, which, during
          the last year, placed 64 titles on The New York Times Best Sellers
          list;

     *    Blockbuster Video, the world's leading retailer of rentable home
          videocassettes, DVDs and video games, with over 6,000 stores in 27

     *    Five theme parks, which entertain more than 13 million visitors
          annually, and create another distribution channel for the
          company's entertainment content;

     *    A significant and growing Internet presence, with brands on some
          of the best-known sites on the Web, including cbs.sportsline.com,
          cbs.marketwatch.com, mtv.com, SonicNet.com, vh1.com, and Nick.com.

Mr. Karmazin added: "The new company's opportunities for growth over the
Internet are also excellent. As you know, we have been dynamically expanding
in new media for the past year or so, adding the CBS brand to some of the
most visible sites on the Web in financial news, sports, entertainment and
e-commerce, among others. Viacom has its own growing Internet presence in a
variety of successful Web sites, most notably mtv.com and Nick.com, which
will join with our growing portfolio of Internet concerns. Here again, the
powerful brands of our two companies  from the CBS Television Network, CBS
News and CBS Sports to MTV, VH1, Nickelodeon and Paramount  will enable us
to establish and maintain the most dynamic and visible Internet strategy in
the media business."

Viacom Deputy Chairmen Tom Dooley and Philippe Dauman, who will continue to
serve on the Board of Directors of the combined company, will leave the
Company on the effective date of the merger.

Mr. Redstone stated: "Viacom would be no more than a dream today if not for
the intelligence, persistence and insight of my two Deputy Chairmen,
Philippe Dauman and Tom Dooley. My thanks to both of them for their
immeasurable contributions over the last decade and beyond. We wouldn't be
here if not for them. They will continue to be my trusted friends and
advisors on the Viacom Board."

The Board of Directors of the new company will consist of the current ten
members of the Viacom Board and eight members of the CBS Board as designated
by CBS.

The transaction is subject to certain closing conditions, including FCC
approval, expiration of the Hart-Scott-Rodino waiting period and the
approval of CBS Corporation shareholders, and is expected to close in the
first half of 2000. CBS's pending acquisition of King World Productions Inc.
was scheduled to be voted on by its shareholders today. The King World
shareholders meeting will be postponed for what is expected to be a short
period. The contemplated split-off of Blockbuster is subject to the receipt
of a revised IRS ruling.

York, New York 10036, agrees to employ you and you agree to accept such
employment upon the following terms and conditions:

          1. Term. The term of your employment hereunder shall commence on the
Effective Time (as defined in the Agreement and Plan of Merger between Viacom
and CBS Corporation ("CBS"), dated as of the date hereof (the "Merger
Agreement"), pursuant to which CBS shall merge with and into Viacom) (the
"Effective Date") and, unless terminated by Viacom or you pursuant to
paragraph 8 hereof, shall continue through and until December 31, 2003. The
period from the Effective Date through December 31, 2003 shall hereinafter be
referred to as the "Employment Term," notwithstanding any earlier termination
pursuant to paragraph 9. In the event that the Merger Agreement is terminated
or otherwise abandoned, this Agreement shall be void ab initio.

          2. Duties. During the Employment Term, you agree to devote your
entire business time, attention and energies to the business of Viacom and its
subsidiaries. This is not intended to prevent you from engaging in other
activities that do not conflict with or interfere with the performance of your
duties and responsibilities hereunder. You will be President and Chief
Operating Officer of Viacom reporting directly and solely to Sumner M.
Redstone, the Chairman of the Board and Chief Executive Officer of Viacom (the
"Chairman"), and, upon the termination of the Chairman's service as Chief
Executive Officer during the Employment Term, you shall be appointed the Chief
Executive Officer. You will perform such duties and have such responsibilities
set forth in Article XIII of the Amended and Restated Certificate of
Incorporation of Viacom to be effective as of the Effective Date (the
"Certificate of Incorporation"), a copy of which is attached hereto as Exhibit
A. You will have such authority as is necessary for the performance of your
obligations hereunder. You shall serve as a member of the Boards of Directors
of Viacom and Circular. Your principal place of business shall be at Viacom's
headquarters in the New York City metropolitan area and you shall not be
required to relocate outside of the New York City metropolitan area. You shall
be entitled to continue to serve on the corporate, charitable and educational
boards of which you are a member as of the date hereof.

          3. Compensation. As the sole compensation for services to be
rendered by you during the Employment Term in all capacities to Viacom, its
subsidiaries and affiliates, you will receive the following compensation.

          (a) Salary: For all the services rendered by you in any capacity to
Viacom, its subsidiaries and affiliates, Viacom agrees to pay you a base
salary at the rate of $1,000,000 per annum ("Salary"), payable in accordance
with Viacom's then effective payroll practices.

          (b) Bonus Compensation: In addition to your Salary, you shall be
entitled to receive bonus compensation for each of the calendar years during
the Employment Term, determined and payable as follows ("Bonus"):

          (i)  Your Bonus for each of the calendar years during the Employment
               Term will be based upon a measurement of performance against
               objectives in accordance with Viacom's Short-Term Incentive
               Plan and its Senior Executive Short-Term Incentive Plan, as the
               same may be amended from time to time (collectively, the
               "STIP"), which objectives shall be no less favorable to you
               than the objectives used to determine the amount of bonus
               payable to any other executive of Viacom whose bonus is based
               in whole or in part on corporate performance and who
               participates in the STIP.

          (ii) Your Target Bonus and Maximum Bonus opportunity for each
               calendar year (prorated for calendar year 2000 by multiplying
               such amount by a fraction, the numerator of which is the number
               of days in 2000 following the Effective Date, and the
               denominator of which is 365) during the Employment Term shall
               be as follows:

                 Year             Target                Maximum

          (iii)Your Bonus for any calendar year shall be payable by February
               28 of the following year (even if not during the Employment
               Term).

          (c) Deferred Compensation: In addition to your Salary and Bonus, you
shall earn, in respect of calendar year 2000 and each calendar year during the
Employment Term after 2000, an additional amount ("Deferred Compensation"),
the payment of which (together with the return thereon as provided in this
paragraph 3(c)) shall be deferred until January of the first calendar year
following the year in which you cease to be an "executive officer" of Viacom,
as defined for purposes of the Securities Exchange Act of 1934, as amended.
The amount of Deferred Compensation for calendar year 2000 shall be
$2,000,000, prorated by multiplying such amount by a fraction, the numerator
of which is the number of days in 2000 following the Effective Date, and the
denominator of which is 365. The amount of Deferred Compensation for calendar
years 2001 through 2003 shall be subject to annual increases each January 1st,
commencing January 1, 2001, in an amount equal to 10% of the sum of your
Salary and Deferred Compensation for the preceding year. Deferred Compensation
shall be credited to a bookkeeping account maintained by Viacom on your
behalf, the balance of which account shall periodically be credited (or
debited) with deemed positive (or negative) return calculated in the same
manner, and at the same times, as the deemed return on your account under the
excess 401(k) plan of Viacom (as such plan may be amended from time to time)
is determined (it being

                                                                             3

understood and agreed that if at any time during which the Deferred
Compensation remains payable your excess 401(k) account balance is distributed
in full to you, your Deferred Compensation account shall continue to be
credited or debited with a deemed return based on the investment portfolio in
which your excess 401(k) account was notionally invested immediately prior to
its distribution). Viacom's obligation to pay the Deferred Compensation
(including the return thereon provided for in this paragraph 3(c)) shall be an
unfunded obligation to be satisfied from the general funds of Viacom.

          (d) Grant: You will be awarded a grant (the "Grant") under Viacom's
1997 Long-Term Management Incentive Plan (the "1997 LTMIP") of stock options
to purchase 2,000,000 shares of Viacom's Class B Common Stock (such number to
be adjusted for any stock split, stock dividend or other similar transaction
that would result in an adjustment under the terms of the 1997 LTMIP if such
options were granted on the date hereof), effective as of the Effective Date,
with an exercise price equal to the fair-market value of Viacom's Class B
Common Stock on the Effective Date. Except as provided herein, the Grant shall
be made in accordance with the standard terms of stock option awards under the
1997 LTMIP (a copy of the standard form of such stock option awards is
attached hereto as Exhibit B), shall vest in three equal installments on the
first, second and third anniversaries of the Effective Date and shall be for a
ten-year term. In the event you cease to be employed by the Company for any
reason upon the expiration of the Employment Term, you shall be able to
exercise the Grant for two years following such termination.

          4. Benefits.

          (a) You shall be entitled to participate in such medical, dental and
life insurance, 401(k), pension and other plans as Viacom may have or
establish from time to time and in which any other Viacom executives are
eligible to participate. The foregoing, however, shall not be construed to
require Viacom to establish any such plans or to prevent the modification or
termination of such plans once established, and no such action or failure
thereof shall affect this Agreement; provided, however, that no modification
of any plans in which you participate shall be made which results in treating
you less favorably than other senior executives of Viacom. It is further
understood and agreed that all benefits (including without limitation,
Viacom's Pension and Excess Pension Plans, short term disability program,
Long-Term Disability program and any supplement thereto, life insurance and
any applicable death benefit) you may be entitled to as an employee of Viacom
shall be based upon your Salary and, your Deferred Compensation, as set forth
in paragraphs 3(a) and (c) hereof, and not upon any bonus compensation due,
payable or paid to you hereunder, except where the benefit plan expressly
provides otherwise. In addition, it is hereby expressly agreed that you shall
retain all benefits that you have accrued under any compensation and benefit
plans of CBS. You shall be entitled to four (4) weeks vacation.

          (b) Viacom shall provide you with no less than Five Million Dollars
($5,000,000) of term life insurance during the Employment Term. You shall have
the right to assign the policy for such life insurance to your spouse or issue
or to a trust or trusts primarily for the benefit of your spouse and/or issue.

          (c) In addition to the benefits described in paragraphs 4(a) and (b)
hereof, Viacom agrees that you shall be credited for service accrued or deemed
accrued prior to the Effective Date with CBS or any of its subsidiaries or
predecessors for all purposes under any employee benefit plans, programs or
arrangement established or maintained by Viacom or any of its subsidiaries;
provided, however that such crediting of service shall not operate to
duplicate any benefit or the funding of any such benefit.

          (d) Notwithstanding anything herein to the contrary, if it is
determined that any payment or benefit provided to you (whether hereunder or
otherwise, and including any payments or benefits resulting from the
transactions contemplated by the Merger Agreement) would be subject to the
excise tax imposed by Section 4999 of the Code or any interest or penalties
with respect to such excise tax (such excise tax, together with any interest
or penalties thereon, is herein referred to as an "Excise Tax"), then you
shall be entitled to an additional cash payment (a "Gross-Up Payment") in an
amount that will place you in the same after-tax economic position that you
would have enjoyed if the Excise Tax had not applied to the payment. The
amount of the Gross-Up Payment shall be determined by Viacom's regular
independent auditors. No Gross-Up Payments shall be payable hereunder if
Viacom's auditors determine that such payments are not subject to an Excise
Tax. Viacom's auditors shall be paid by Viacom for services performed
hereunder.

          5. Business Expenses. During the Employment Term, you shall be
reimbursed for such reasonable travel and other expenses incurred in the
performance of your duties hereunder as are customarily reimbursed to senior
executives of Viacom.

          6. Perquisites. You shall be eligible for all perquisites made
available by Viacom from time to time during the Employment Term to other
senior executives of Viacom. Without limiting the generality of the foregoing,
you shall be entitled to (i) a car allowance and insurance in accordance with
Viacom's policy and (ii) use of a private airplane on a basis no less
favorable than as provided by CBS to you as of the date of execution of this
Agreement, or, if more beneficial to you, as provided by Viacom to any of its
senior executives.

          7. Exclusive Employment, Confidential Information, Etc.

          (a) Non-Competition. You agree that your employment hereunder is on
an exclusive basis, and that during the period of your employment hereunder
and, in the event during the Employment Term, of (x) a termination of your
employment pursuant to paragraph 9(a) hereof or (y) your resignation without
Good Reason, for a period of eighteen (18) months following the date of such
termination or resignation, as the case may be (the "Non-Compete Period"), you
will not engage in any other business activity which is in conflict with your
duties and obligations hereunder. You agree that during the Non-Compete Period
you shall not directly or indirectly engage in or participate as an officer,
employee, director, agent of or consultant for any business directly
competitive with that of Viacom, nor shall you make any investments in any
company or business competing with Viacom; provided, however, that nothing
herein shall prevent you from investing as less than a two (2%) percent
shareholder in the securities of any company listed on a national securities
exchange or quoted on an automated quotation system.

          (b) Confidential Information. You agree that you shall not, during
the Employment Term or at any time thereafter, use for your own purposes, or
disclose to or for the benefit of any third party, any trade secret or other
confidential information of Viacom or any of its affiliates or predecessors
(except as may be required by law or in the performance of your duties
hereunder consistent with Viacom's policies) and that you will comply with any
confidentiality obligations of Viacom to a third party, whether under
agreement or otherwise. Notwithstanding the foregoing, confidential
information shall be deemed not to include information which (i) is or becomes
generally available to the public other than as a result of a disclosure by
you or any other person who directly or indirectly receives such information
from you or at your direction or (ii) is or becomes available to you on a
non-confidential basis from a source which is entitled to disclose it to you.

          (c) No Employee Solicitation. You agree that, during the Employment
Term and for one (1) year thereafter, you shall not, directly or indirectly,
engage, employ, or solicit the employment of any person who is then or has
been within six (6) months prior thereto, an employee of Viacom or any of
Viacom's affiliates or predecessors.

          (d) Viacom Ownership. The results and proceeds of your services
hereunder, including, without limitation, any works of authorship resulting
from your services during your employment with Viacom and/or any of its
affiliates or predecessors and any works in progress, shall be
works-made-for-hire and Viacom shall be deemed the sole owner throughout the
universe of any and all rights of whatsoever nature therein, whether or not
now or hereafter known, existing, contemplated, recognized or developed, with
the right to use the same in perpetuity in any manner Viacom determines in its
sole discretion without any further payment to you whatsoever. If, for any
reason, any of such results and proceeds shall not legally be a work-for-hire
and/or there are any rights which do not accrue to Viacom under the preceding
sentence, then you hereby irrevocably assign and agree to assign any and all
of your right, title and interest thereto, including, without limitation, any
and all copyrights, patents, trade secrets, trademarks and/or other rights of
whatsoever nature therein, whether or not now or hereafter known, existing,
contemplated, recognized or developed to Viacom, and Viacom shall have the
right to use the same in perpetuity throughout the universe in any manner
Viacom determines without any further payment to you whatsoever. You shall,
from time to time, as may be requested by Viacom, do any and all things which
Viacom may deem useful or desirable to establish or document Viacom's
exclusive ownership of any and all rights in any such results and proceeds,
including, without limitation, the execution of appropriate copyright and/or
patent applications or assignments. To the extent you have any rights in the
results and proceeds of your services that cannot be assigned in the manner
described above, you unconditionally and irrevocably waive the enforcement of
such rights. This paragraph 7(d) is subject to, and shall not be deemed to
limit, restrict, or constitute any waiver by Viacom of any rights of ownership
to which Viacom may be entitled by operation of law by virtue of Viacom or any
of its affiliates or predecessors being your employer.

          (e) Litigation. You agree that, during the Employment Term, for one
(1) year thereafter and, if longer, during the pendancy of any litigation or
other proceeding, (i) you shall not communicate with anyone (other than your
own attorneys and tax advisors and, except to the extent required by law or
necessary in the performance of your duties hereunder) with respect to the
facts or subject matter of any pending or potential litigation, or regulatory
or administrative proceeding involving any of Viacom's affiliates or
predecessors, other than any litigation or other proceeding in which you are a
party-in-opposition, without giving prior notice to Viacom or Viacom's
counsel, and (ii) in the event that any other party attempts to obtain
information or documents from you with respect to matters possibly related to
such litigation or other proceeding, you shall promptly so notify Viacom's
counsel unless you are prohibited from doing so under applicable law.

          (f) No Right to Write Books, Articles, Etc. During the Employment
Term, except as authorized by Viacom, you shall not prepare or assist any
person or entity in the preparation of any books, articles, television or
motion picture productions or other creations, concerning Viacom or any of
Viacom's affiliates or predecessors or any of their officers, directors,
agents, employees, suppliers or customers.

          (g) Return of Property. All documents, data, recordings, or other
property, whether tangible or intangible, including all information stored in
electronic form, obtained or prepared by or for you and utilized by you in the
course of your employment with Viacom or any of its affiliates or predecessors
shall remain the exclusive property of Viacom. In the event


<PAGE>


                                                                             6

of the termination of your employment for any reason, Viacom reserves the
right, to the extent permitted by law and in addition to any other remedy
Viacom may have, to deduct from any monies otherwise payable to you the
following: (i) the full amount of any debt you owe to Viacom or any of its
affiliates or predecessors at the time of or subsequent to the termination of
your employment with Viacom, and (ii) the value of the Viacom property which
you retain in your possession after the termination of your employment with
Viacom. In the event that the law of any state or other jurisdiction requires
the consent of an employee for such deductions, this Agreement shall serve as
such consent.

          (h) Non-Disparagement. You and, to the extent set forth in the next
sentence, Viacom agree that each party shall not, during the Employment Term
and for one (1) year thereafter criticize, ridicule or make any statement
which disparages or is derogatory of the other party in any communications
with any customer or client. Viacom's obligations under the preceding sentence
shall be limited to communications by its senior corporate executives having
the rank of Senior Vice President or above.

          (i) Injunctive Relief. Viacom has entered into this Agreement in
order to obtain the benefit of your unique skills, talent, and experience. You
acknowledge and agree that any violation of paragraphs 7(a) through (k) hereof
will result in irreparable damage to Viacom, and, accordingly, Viacom may
obtain injunctive and other equitable relief for any breach or threatened
breach of such paragraphs, in addition to any other remedies available to
Viacom.

          (j) Survival; Modification of Terms. Your obligations under
paragraphs 7(a) through (i) hereof shall remain in full force and effect for
the entire period provided therein notwithstanding the termination of the
Employment Term pursuant to paragraph 9 hereof or otherwise. You and Viacom
agree that the restrictions and remedies contained in paragraphs 7(a) through
(k) are reasonable and that it is your intention and the intention of Viacom
that such restrictions and remedies shall be enforceable to the fullest extent
permissible by law. If it shall be found by a court of competent jurisdiction
that any such restriction or remedy is unenforceable but would be enforceable
if some part thereof were deleted or the period or area of application
reduced, then such restriction or remedy shall apply with such modification as
shall be necessary to make it enforceable.

          (k) No Selling of Viacom Stock without Board Consent. In
consideration of your employment hereunder, you hereunder agree that, except
as otherwise provided herein, during the period commencing on the date hereof
and ending on the third anniversary of the Effective Date, you shall not sell
or dispose of (nor exercise any limited rights or stock appreciation rights
with respect to) any shares of capital stock of CBS or Viacom held by you,
your immediate family members (which does not include your former spouse), or
trusts or other entities in which you or your immediate family members have a
controlling interest or are beneficiaries (together, the "Family Affiliates"
and each, a "Family Affiliate") that you or any Family Affiliate now hold, or
in the future may acquire, including, without limitation, shares that you or
any Family Affiliate receive pursuant to the transactions contemplated by the
Merger Agreement (whether in exchange for shares of CBS common stock or
otherwise), under any stock options or other equity-based compensation awards
made to you by CBS or by Viacom under this Agreement or under any other
agreement awarding you shares of capital stock of Viacom, without first
obtaining the consent of (i) if prior to the Effective Date, the Chairman, or
(ii) if on or following the Effective Date, fourteen of the eighteen members
of the Board of Viacom. This restriction shall lapse in the event that, during
the Employment Term, you are terminated without Cause, resign for Good Reason,
die or become disabled. Notwithstanding the foregoing, between the first
anniversary of the Effective Date and the second anniversary of the Effective
Date you and the Family Affiliates collectively may sell or dispose of a
number of


<PAGE>


                                                                             7

shares equal to up to 10% of the shares held by you and the Family Affiliates
on the Effective Date (including, for this purpose, the shares underlying any
equity-based compensation awards held by you on the Effective Date, but not
shares underlying any equity-based compensation awards granted to you pursuant
to paragraph 3(d) or at any time after the Effective Date). Between the second
anniversary of the Effective Date and the third anniversary of the Effective
Date, you and the Family Affiliates collectively may sell or dispose of a
number of shares equal to up to 10% of the shares held by you and the Family
Affiliates on the second anniversary of the Effective Date (including, for
this purpose, the shares underlying any equity-based compensation awards held
by you on the Effective Date, but not shares underlying any equity-based
compensation awards granted to you pursuant to paragraph 3(d) or at any time
after the Effective Date), plus any shares that were not sold or disposed of
by you and the Family Affiliates collectively under the prior year's limits.
Notwithstanding the foregoing, you may transfer shares to Family Affiliates,
but such shares shall remain subject to the restrictions contained in this
paragraph 7(k).

          8. Incapacity. In the event you become totally medically disabled at
any time during the Employment Term and are not expected to be able to
substantially perform your duties for a six (6) consecutive month period, the
Chairman, at any time after such disability has in fact continued for 60
consecutive days, may determine that Viacom requires such duties and
responsibilities be performed by another executive. In the event you become
disabled, you will first receive benefits under Viacom's short-term disability
program for the first 26 weeks of consecutive absence. Thereafter, you will be
eligible to receive benefits under Viacom's Long-Term Disability ("LTD")
program or any supplement thereto, in accordance with its terms. Upon receipt
of benefits under the LTD program you will also be entitled to receive,
subject to applicable withholding taxes:

          (i)  a Target Bonus prorated for the portion of calendar year
               through the date on which you become eligible to receive
               benefits under the LTD program, payable at the time that the
               Bonus for such calendar year would otherwise be paid;

          (ii) prorated Deferred Compensation for the calendar year in which
               such benefits commence and Deferred Compensation attributable
               to prior calendar years, payable, together with the return
               thereon as provided in paragraph 3(c), prior to January 31 of
               the calendar year following the calendar year in which such
               benefits commence;

         (iii) stock options granted to you under the 1997 LTMIP which are
               exercisable on or prior to the date as of which benefits
               commence under the LTD program or that would have vested and
               become exercisable on or before the last day of the Employment
               Term will be exercisable for two (2) years after the date as of
               which such benefits commence or, if later, until December 31,
               2003, but in no event may such stock options be exercised
               following the expiration date of such stock options; and

In the event that you thereafter become able to substantially perform your
duties, you will then be entitled to receive from Viacom your Salary and
Deferred Compensation at the rate being paid to you immediately prior to the
commencement of such disability, and your Bonus calculated pursuant to
paragraph 3(b) hereof, through the remainder of the Employment Term reduced by
any employment compensation earned by you for any work or service performed
for any other person.

          (a) Termination for Cause. Viacom may, at its option, terminate your
employment under this Agreement forthwith for "cause", and Viacom shall
thereafter have no further obligations under this Agreement, including,
without limitation, any obligation to pay Salary or Bonus or provide benefits
under this Agreement; provided, however, that Viacom may terminate this
Agreement pursuant to this paragraph only with the affirmative vote of
fourteen of the eighteen members of the Board of Viacom at a meeting called
for such purpose at which you and a counsel of your choosing shall have an
opportunity to be heard. For purposes of this Agreement, termination of this
Agreement for "cause" shall mean termination for embezzlement, fraud or other
conduct which would constitute a felony, conviction of a felony, or willful
unauthorized disclosure of confidential information, or if you at any time
materially breach this Agreement (including, without limitation, your failure,
neglect of or refusal to substantially perform your obligations hereunder as
set forth in paragraphs 2, 7(k) and 12 hereof), except in the event of your
disability as set forth in paragraph 8. Anything herein to the contrary
notwithstanding, Viacom will give you written notice prior to terminating this
Agreement for your material breach setting forth the exact nature of any
alleged breach and the conduct required to cure such breach. Except for a
breach which by its nature cannot be cured, you shall have ten (10) business
days from the giving of such notice within which to cure and within which
period Viacom cannot terminate this Agreement for the stated reasons.

          (b) Good Reason Termination. You may terminate your employment
hereunder for "Good Reason" at any time during the Employment Term by written
notice to Viacom not more than thirty (30) days after the occurrence of the
event constituting "Good Reason". Such notice shall state an effective date no
earlier than thirty (30) business days after the date it is given. Viacom
shall have ten (10) business days from the giving of such notice within which
to cure. Good Reason shall mean any of the following, without your prior
written consent, other than in connection with the termination of your
employment for "cause" (as defined above) or in connection with your permanent
disability:

          (i)  the assignment to you by Viacom of duties substantially
               inconsistent with your positions, duties, responsibilities,
               titles or offices, the withdrawal of a material part of your
               responsibilities or a change in your reporting relationship, as
               set forth in paragraph 2 or in Article XIII of the Certificate
               of Incorporation as in effect on the Effective Date;

          (ii) a reduction by Viacom in your Salary or Target Bonus as in
               effect at the date hereof or as the same may be increased from
               time to time during the Employment Term;

         (iii) Viacom's requiring you to be based anywhere other than the New
               York City metropolitan area, except for required travel on
               Viacom's business to any extent substantially consistent with
               business travel obligations of other senior executives of
               Viacom;

          (iv) Viacom's violation of Article XIII of the Certificate of
               Incorporation; or

          (v) the material breach by Viacom of its obligations hereunder.

          (c) Termination Without Cause. Viacom may terminate your employment
under this Agreement without "cause" (as defined above) at any time during the
Employment

                                                                             9

Term by written notice to you; provided, however, that Viacom may terminate
your employment pursuant to this paragraph only with the affirmative vote of
fourteen of the eighteen members of the Board of Viacom.

          (d) Termination Payments, Etc. In the event that your employment
terminates pursuant to paragraph 9(b) or 9(c) hereof, you shall be entitled to
receive, subject to applicable withholding taxes:

          (i)  your Salary as provided in paragraph 3(a) until the end of the
               Employment Term, payable in accordance with Viacom's then
               effective payroll practices;

          (ii) bonus compensation for each calendar year during the Employment
               Term equal to your Target Bonus as set forth in paragraph 3(b);

         (iii) Deferred Compensation for each calendar year during the
               Employment Term as set forth in paragraph 3(c); Deferred
               Compensation attributable to the calendar year in which the
               termination pursuant to paragraph 9(b) or 9(c) hereof occurs
               and to prior calendar years shall be payable, together with the
               return thereon as provided in paragraph 3(c), prior to January
               31 of the calendar year following such termination; and
               Deferred Compensation attributable to subsequent calendar years
               shall be payable, together with the return thereon as provided
               in paragraph 3(c), prior to January 31 of each such following
               calendar year;

          (iv) your perquisites as provided in paragraph 6 until the end of
               the Employment Term, payable in accordance with Viacom's then
               effective payroll practices;

          (v)  medical and dental insurance coverage until the end of the
               Employment Term or, if earlier, the date on which you become
               eligible for medical and dental coverage from a third party
               employer; during this period, Viacom will pay an amount equal
               to the applicable COBRA premiums (or such other amounts as may
               be required by applicable law) (which amount will be included
               in your income for tax purposes to the extent required by
               applicable law); at the end of such period, you may elect to
               continue your medical and dental insurance coverage at your own
               expense for the balance, if any, of the period required by law;

          (vi) life insurance coverage as set forth in paragraph 4(b) until
               the end of the Employment Term (the amount of such insurance to
               be reduced by the amount of any insurance provided by a new
               employer without cost to you);

         (vii) stock options granted to you under the 1997 LTMIP which are

     equal number of shares of Class B Common Stock by surrendering the
     certificates for such shares, accompanied by payment of documentary,
     stamp or similar issue or transfer taxes, if any, along with a written
     notice by such record holder to the Corporation stating that such record
     holder desires to convert such shares into the same number of shares of

     such Class B Common Stock to the persons named therein, setting forth the

Restated Certificate of Incorporation, the property and business of the
Corporation shall be controlled and managed by or under the direction of its
Board of Directors. In furtherance, and not in limitation of the powers
conferred by the laws of the State of Delaware, the Board of Directors is
expressly authorized, subject in all cases to Article XIII of this Restated
Certificate of Incorporation:

          (a) To make, alter, amend or repeal the By-Laws of the Corporation;
     provided that no By-Laws hereafter adopted shall invalidate any prior act
     of the Directors that would have been valid if such By-Laws had not been
     adopted;

          (b) To determine the rights, powers, duties, rules and procedures
     that affect the power of the Board of Directors to manage and direct the
     property, business and affairs of the Corporation, including, without
     limitation, the power to designate and empower committees of the Board of
     Directors, to elect, appoint and empower the officers and other agents of

     the manner of taking Board action; and

          (c) To exercise all such powers and do all such acts as may be
     exercised by the Corporation, subject to the provisions of the laws of
     the State of Delaware, this Restated Certificate of Incorporation, and

                                  ARTICLE VI

                         INDEMNIFICATION OF DIRECTORS,
                              OFFICERS AND OTHERS

     (1) Action Not By or on Behalf of Corporation. The Corporation shall
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative (other than an action by or
in the right of the Corporation) by reason of the fact that he is or was a
Director, officer, employee or agent of the Corporation, or is or was serving
at the request of the Corporation as a director, officer, employee or agent
(including, without limitation, a trustee) of another corporation,
partnership, joint venture, trust or other enterprise, against judgments,
fines, amounts paid in settlement and expenses (including, without limitation,
attorneys' fees), actually and reasonably incurred by him in connection with
such action, suit or proceeding if he acted in good faith and in a manner
reasonably believed to be in or not opposed to the best interests of the
Corporation, and with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The termination of any
action, suit or proceeding by judgment, order, settlement, conviction, or upon
a plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was unlawful.

     (2) Action By or on Behalf of Corporation. The Corporation shall
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action or suit by or in the right of
the Corporation to procure a judgment in its favor by reason of the fact that
he is or was a Director, officer, employee or agent of the

                                       5

<PAGE>


Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership,
joint venture, trust, or other enterprise against expenses (including, without
limitation, attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted
in good faith and in a manner he reasonably believed to be in or not opposed
to the best interests of the Corporation, except that no indemnification shall
be made in respect of any claim, issue or matter as to which such person shall
have been adjudged to be liable to the Corporation unless and only to the
extent that the court in which such action or suit was brought shall determine
upon application that, despite the adjudication of liability and in view of
all of the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the court shall deem proper.

     (3) Successful Defense. To the extent that a present or former Director,
officer, employee or agent of the Corporation has been successful on the
merits or otherwise in defense of any action, suit or proceeding referred to
in Section 1 or 2 of this Article VI, or in defense of any claim, issue or
matter therein, he shall be indemnified against expenses (including, without
limitation, attorneys' fees) actually and reasonably incurred by him in
connection therewith.

     (4) Determination of Right to Indemnification in Certain Circumstances.
Any indemnification under Section 1 or 2 of this Article VI (unless ordered by
a court) shall be made by the Corporation only as authorized in the specific
case upon a determination that indemnification of the present or former
Director, officer, employee or agent is proper in the circumstances because he
has met the applicable standard of conduct set forth in Section 1 or 2 of this
Article IV. Such determination shall be made, with respect to a person who is
a Director or officer at the time of such determination, (1) by a majority
vote of the Directors who are not parties to such action, suit or proceeding,
even though less than a quorum, or (2) by a committee of such Directors
designated by a majority vote of such Directors, even though less than a
quorum, or (3) if there are no such Directors, or if such Directors so direct,
by independent legal counsel in a written opinion, or (4) by the stockholders
of the Corporation entitled to vote thereon.

     (5) Advance Payment of Expenses.

     (a) Expenses (including attorneys' fees) incurred by a Director or
officer in defending any civil, criminal, administrative or investigative
action, suit or proceeding shall be paid by the Corporation in advance of the
final disposition of such action, suit or proceeding upon receipt of an
undertaking by or on behalf of such Director or officer, to repay such amount
if it shall ultimately be determined that he is not entitled to be indemnified
by the Corporation as authorized in this Article.


                                       6

<PAGE>


     (b) Expenses (including attorneys' fees) incurred by any other employee
or agent in defending any civil, criminal, administrative or investigative
action, suit or proceeding may be paid by the Corporation in advance of the
final disposition of such action, suit or proceeding upon such terms and
conditions, if any, as the Corporation deems appropriate.

     (6) Not Exclusive. The indemnification and advancement of expenses
provided by, or granted pursuant to, the other sections of this Article VI
shall not be deemed exclusive of any other rights to which a person seeking
indemnification or advancement of expenses may be entitled under any statute,
by-law, agreement, vote of stockholders or disinterested Directors or
otherwise, both as to action in his official capacity and as to action in
another capacity while holding such office. Without limiting the foregoing,
the Corporation is authorized to enter into an agreement with any Director,
officer, employee or agent of the Corporation providing indemnification for
such person against expenses, including, without limitation, attorneys' fees,
judgments, fines and amounts paid in settlement that result from any
threatened, pending or completed action, suit, or proceeding, whether civil,
criminal, administrative or investigative, including, without limitation, any
action by or in the right of the Corporation, that arises by reason of the
fact that such person is or was a Director, officer, employee or agent of the
Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, to the full extent allowed by law,
except that no such agreement shall provide for indemnification for any
actions that constitute fraud, actual dishonesty or willful misconduct.

     (7) Insurance. The Corporation may purchase and maintain insurance on
behalf of any person who is or was a Director, officer, employee or agent of
the Corporation, or is or was serving as the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise against any liability asserted
against him and incurred by him in any such capacity, or arising out of his
status as such, whether or not the Corporation would have the power to
indemnify him against such liability under the provisions of this Article VI.

     (8) Certain Definitions. For the purposes of this Article VI, (A) any
Director, officer, employee or agent of the Corporation who shall serve as a
director, officer, employee or agent of any other corporation, joint venture,
trust or other enterprise of which the Corporation, directly or indirectly, is
or was a stockholder or creditor, or in which the Corporation is or was in any
way interested, or (B) any director, officer, employee or agent of any
subsidiary corporation, joint venture, trust or other enterprise wholly owned
by the Corporation, shall be deemed to be serving as such director, officer,
employee or agent at the request of the Corporation, unless the Board of
Directors of the

                                       7

Corporation shall determine otherwise. In all other instances where any person
shall serve as a director, officer, employee or agent of another corporation,
joint venture, trust or other enterprise of which the Corporation is or was a
stockholder or creditor, or in which it is or was otherwise interested, if it
is not otherwise established that such person is or was serving as such
director, officer, employee or agent at the request of the Corporation, the
Board of Directors of the Corporation may determine whether such service is or
was at the request of the Corporation, and it shall not be necessary to show
any actual or prior request for such service. For purposes of this Article VI,
references to a corporation include all constituent corporations absorbed in a
consolidation or merger as well as the resulting or surviving corporation so
that any person who is or was a director, officer, employee or agent of such a
constituent corporation or is or was serving at the request of such
constituent corporation as a director, officer, employee or agent of another
corporation, joint venture, trust or other enterprise shall stand in the same
position under the provisions of this Article VI with respect to the resulting
or surviving corporation as he would if he had served the resulting or
surviving corporation in the same capacity. For purposes of this Article VI,
references to "other enterprises" shall include employee benefit plans;
references to "fines" shall include any excise taxes assessed on a person with
respect to an employee benefit plan; and references to "serving at the request
of the Corporation" shall include any service as a director, officer, employee
or agent of the Corporation which imposes duties on, or involves services by,
such director, officer, employee, or agent with respect to an employee benefit
plan, its participants, or beneficiaries, and a person who acted in good faith
and in a manner he reasonably believed to be in the interest of the
participants and beneficiaries of an employee benefit plan shall be deemed to
have acted in a manner "not opposed to the best interests of the Corporation"
as referred to in this Article VI.

     (9) The indemnification and advancement of expenses provided by, or
granted pursuant to, this Article VI shall, unless otherwise provided when
authorized or ratified, continue as to a person who has ceased to be a
director, officer, employee or agent and shall inure to the benefit of the
heirs, executors and administrators of such a person.

                                  ARTICLE VII

permitted by Delaware law as now in effect or hereafter amended. In particular
no Director of the Corporation shall be liable to the Corporation or any of
its stockholders for monetary damages for breach of fiduciary duty as a
director, except for liability (i) for any breach of the Director's duty of
loyalty to the Corporation or its stockholders, (ii) for acts or omissions not
in good faith or

                                       8

<PAGE>


which involve intentional misconduct or a knowing violation of law, (iii)
under Section 174 of the Delaware General Corporation Law, as the same exists
or hereafter may be amended, or (iv) for any transaction from which the
Director derived an improper personal benefit.

     (b) Any repeal or modification of the foregoing paragraph (a) by the
stockholders of the Corporation entitled to vote thereon shall not adversely
affect any right or protection of a director of the Corporation existing at
the time of such repeal or modification.

     (c) If the General Corporation Law of the State of Delaware is amended to
authorize corporate action further eliminating or limiting the liability of
directors, then a director of the Corporation, in addition to the
circumstances in which he is not now liable, shall be free of liability to the
fullest extent permitted by the General Corporation Law of the State of
Delaware, as so amended.

                                 ARTICLE VIII

                         RESERVATION OF RIGHT TO AMEND

     Subject to Article XIII of this Restated Certificate of Incorporation,
the Corporation reserves the right to amend, alter, change or repeal any
provision contained in this Restated Certificate of Incorporation in the
manner now or hereafter prescribed by law, and all the provisions of this
Restated Certificate of Incorporation and all rights and powers conferred in
this Restated Certificate of Incorporation on stockholders, directors and
officers are subject to this reserved power.

     Each reference in the Restated Certificate of Incorporation to "the
Restated Certificate of Incorporation", "hereunder", "hereof", or words of
like import and each reference to the Restated Certificate of Incorporation

                                  ARTICLE IX

                                 VOTING RIGHTS

     (1) Class A Common Stock. In addition to any other approval required by
law or by this Restated Certificate of Incorporation, the affirmative vote of
a majority of the then outstanding shares of Class A Common Stock, voted
separately as a class, shall be necessary to approve any consolidation of the

another corporation or any merger of any other corporation into the
Corporation pursuant to which shares of Common Stock are converted into or
exchanged for any securities or any other consideration.

     (2) Preferred Stock. Subject to Article XIII of this Restated Certificate
of Incorporation, in addition to any other approval required by law or by this

                                   ARTICLE X

                                STOCK OWNERSHIP
                      AND THE FEDERAL COMMUNICATIONS LAWS

     (1) Requests for Information. So long as the Corporation or any of its
subsidiaries holds any authorization from the Federal Communications
Commission (or any successor thereto), if the Corporation has reason to
believe that the ownership, or proposed ownership, of shares of capital stock
of the Corporation by any stockholder or any person presenting any shares of
capital stock of the Corporation for transfer into his name (a "Proposed
Transferee") may be inconsistent with, or in violation of, any provision of
the Federal Communications Laws (as hereinafter defined), such stockholder or
Proposed Transferee, upon request of the Corporation, shall furnish promptly
to the Corporation such information (including, without limitation,
information with respect to citizenship, other ownership interests and
affiliations) as the Corporation shall reasonably request to determine whether
the ownership of, or the exercise of any rights with respect to, shares of
capital stock of the Corporation by such stockholder or Proposed Transferee is
inconsistent with, or in violation of, the Federal Communications Laws. For
purposes of this Article X, the term "Federal Communications Laws" shall mean
any law of the United States now or hereafter in effect (and any regulation
thereunder) pertaining to the ownership of, or the exercise of the rights of
ownership with respect to, capital stock of corporations holding, directly or
indirectly, Federal Communications Commissions authorizations, including,
without limitation, the Communications Act of 1934, as amended (the
"Communications Act"), and regulations thereunder pertaining to the ownership,
or the exercise of the rights of ownership, of capital stock of corporations
holding, directly or indirectly, Federal Communications Commission
authorizations, by (i) aliens, as defined in or under the Communications Act,
as it may be amended from time to time, (ii) persons and entities having
interests in television or radio stations, daily newspapers and cable
television systems or (iii) persons or entities, unilaterally or otherwise,
seeking direct or indirect control of the Corporation, as construed under the
Communications Act, without having obtained any requisite prior Federal
regulatory approval to such control.

     (2) Denial of Rights, Refusal to Transfer. If any stockholder or Proposed
Transferee from whom information is requested should fail to respond to such
request pursuant to Section (1) of this Article or the Corporation shall
conclude

                                      10

<PAGE>


that the ownership of, or the exercise of any rights of ownership with respect
to, shares of capital stock of the Corporation, by such stockholder or
Proposed Transferee, could result in any inconsistency with, or violation of,
the Federal Communications Laws, the Corporation may refuse to permit the
transfer of shares of capital stock of the Corporation to such Proposed
Transferee, or may suspend those rights of stock ownership the exercise of
which would result in any inconsistency with, or violation of, the Federal
Communications Laws, such refusal of transfer or suspension to remain in
effect until the requested information has been received and the Corporation
has determined that such transfer, or the exercise of such suspended rights,
as the case may be, is permissible under the Federal Communications Laws, and
the Corporation may exercise any and all appropriate remedies, at law or in
equity, in any court of competent jurisdiction, against any such stockholder
or Proposed Transferee, with a view towards obtaining such information or
preventing or curing any situation which would cause any inconsistency with,
or violation of, any provision of the Federal Communications Laws.

     (3) Legends. The Corporation may note on the certificates of its capital
stock that the shares represented by such certificates are subject to the
restrictions set forth in this Article.

     (4) Certain Definitions. For purposes of this Article, the word "person"
shall include not only natural persons but partnerships, associations,
corporations, joint ventures and other entities, and the word "regulation"
shall include not only regulations but rules, published policies and published
controlling interpretations by an administrative agency or body empowered to
administer a statutory provision of the Federal Communications Laws.

                                  ARTICLE XI

                   TRANSACTIONS WITH DIRECTORS AND OFFICERS

     No contract or transaction between the Corporation and one or more of its
directors or officers, or between the Corporation and any other corporation,
partnership, association, or other organization in which one or more of its
directors or officers are directors or officers, or have a financial interest,
shall be void or voidable solely for this reason, or solely because the
director or officer is present at or participates in the meeting of the board
or committee thereof which authorizes the contract or transaction, or solely
because his or their votes are counted for such purpose if (a) the material
facts as to his relationship or interest and as to the contract or transaction
are disclosed or are known to the Board of Directors or the committee, and the
Board of Directors or the committee in good faith authorizes the contract or
transaction by the affirmative votes of a majority of the disinterested
directors, even though the disinterested directors be less than a quorum, or
(b) the material facts as to his relationship or interest and as to

                                      11

<PAGE>


the contract or transaction are disclosed or are known to the stockholders
entitled to vote thereon, and the contract or transaction is specifically
approved in good faith by vote of such stockholders, or (c) the contract or
transaction is fair as to the Corporation as of the time it is authorized,
approved or ratified by the Board of Directors, a committee thereof, or the
stockholders entitled to vote thereon. Common or interested directors may be
counted in determining the presence of a quorum at a meeting of the Board of
Directors or of a committee which authorizes the contract or transaction.

                                  ARTICLE XII

     Whenever a compromise or arrangement is proposed between this Corporation
and its creditors or any class of them and/or between this Corporation and its
stockholders or any class of them, any court of equitable jurisdiction within
the State of Delaware may, on the application in a summary way of this
Corporation or of any creditor or stockholder thereof or on the application of
any receiver or receivers appointed for this Corporation under the provisions
of Section 291 of Title 8 of the Delaware Code or on the application of
trustees in dissolution or of any receiver or receivers appointed for this
Corporation under the provisions of Section 279 of Title 8 of the Delaware
Code order a meeting of the creditors or class of creditors, and/or of the
stockholders or class of stockholders of this Corporation, as the case may be,
to be summoned in such manner as the said court directs. If a majority in
number representing three-fourths in value of the creditors or class of
creditors, and/or of the stockholders or class of stockholders of this
Corporation, as the case may be, agrees to any compromise or arrangement and
to any reorganization of the Corporation as a consequence of such compromise
or arrangement, the said compromise or arrangement and the said reorganization
shall, if sanctioned by the court to which the said application has been made,
be binding on all the creditors or class of creditors, and/or on all the
stockholders or class of stockholders, of this Corporation, as the case may
be, and also on this Corporation.

company which is a subsidiary of the Corporation, to take such steps as the
Board of Directors reasonably determines are necessary to implement corporate
governance arrangements applicable to such subsidiary in a manner as
consistent as practicable with the provisions contained in this Restated
