              Section 1.1 Grant of Stock Options. The Stock Options have been

Certificate that are not otherwise defined in the Certificate shall have the
meanings assigned to them in Article III hereof. The Stock Options are not
intended to be, or qualify as, "Incentive Stock Options" within the meaning of
section 422 of the Code.

              Section 1.2  Terms of Stock Options.

              (a) Vesting. The Stock Options shall be exercisable only to the
       extent the Participant is vested therein. The Stock Options shall vest
       [Insert Vesting Schedule - generally Stock Options vest in four equal
       installments on the first, second, third and fourth anniversaries of the
       Date of Grant].

              (b) Option Period. Except as provided in Section 1.2(c) hereof,
       the period during which the Stock Options may be exercised shall expire
       on the tenth anniversary of the Date of Grant (the "Expiration Date").

              (c) Exercise in the Event of Termination of Employment,
       Retirement, Permanent Disability or Death.

                   (i) Exercise in the Event of Termination of Employment other
              than for Cause, Retirement, Permanent Disability or Death. In the
              event of a termination of the Participant's employment other than
              for Cause or the Participant's Retirement, Permanent Disability or
              death, the Participant's Outstanding Stock Options can be
              exercised in accordance with the following provisions:


<PAGE>


                        (A) if the Participant ceases to be an employee of the
                   Company or any of its Subsidiaries by reason of the voluntary
                   termination by the Participant or the termination by the
                   Company or any of its Subsidiaries other than for Cause, his
                   or her Outstanding Stock Options may be exercised to the
                   extent then exercisable until the earlier of six months after
                   the date of such termination (or such longer period as may be
                   determined by the Committee, in its discretion) or the
                   Expiration Date;

                        (B) if the Participant ceases to be an employee of the
                   Company or any of its Subsidiaries by reason of the
                   Participant's Retirement, the Participant may exercise his or
                   her Outstanding Stock Options to the extent exercisable on
                   the date of Retirement until the earlier of the third
                   anniversary of such date (or such longer period as may be
                   determined by the Committee, in its discretion) or the
                   Expiration Date;

                        (C) if the Permanent Disability of the Participant
                   occurs, his or her Outstanding Stock Options may be
                   exercised to the extent exercisable upon the date of the
                   onset of such Permanent Disability until the earlier of the
                   third anniversary of such date (or such longer period as may
                   be determined by the Committee, in its discretion) or the
                   Expiration Date; and

                        (D) if a Participant dies during a period during which
                   his or her Stock Options could have been exercised by him or
                   her, his or her Outstanding Stock Options may be exercised
                   to the extent exercisable at the date of death by the person
                   who acquired the right to exercise such Stock Options by
                   will or the laws of descent and distribution or permitted
                   transfer until the earlier of the second anniversary of the
                   date of death (or such longer period as may be determined by
                   the Committee, in its discretion) or the Expiration Date.

              Upon the occurrence of an event described in clauses (A), (B), (C)
              or (D) of this Section 1.2(c)(i), all rights with respect to Stock
              Options that are not vested as of such event will be relinquished.
              A "termination of employment" occurs, for purposes of the Plan,
              when a Participant no longer works for the Company or any of its
              Subsidiaries. For the avoidance of doubt, the employment of a
              Participant who works for a Subsidiary shall terminate, for Plan
              purposes, on the date on which the Participant's employing company
              ceases to be a Subsidiary.

                   (ii) Termination for Cause. If the Participant's employment
              with the Company or any of its Subsidiaries ends due to a
              Termination for Cause then, unless the Committee in its discretion
              determines otherwise, all Outstanding Stock Options, whether or
              not then vested, shall terminate effective as of the date of such
              termination.

                  (iii) Exercise Periods following Termination of Employment,
              Retirement, Permanent Disability or Death. For the purposes of
              determining the dates on which Stock Options may be exercised
              following a termination of employment or Retirement, Permanent
              Disability or death, the day following the date of termination of
              employment or Retirement, Permanent Disability or death shall be
              the first day of the exercise period and the Stock Options may be
              exercised up to and including the last business day falling within
              the exercise period. Thus, if the last day of the exercise period
              is not a business day, then the last date the Stock Options may be
              exercised is the last business day preceding the end of the
              exercise period.

              Section 1.3  Exercise of Stock Options.

              (a) Whole or Partial Exercise. Subject to the restrictions of
       Section 1.2(b) hereof, the Participant may exercise all vested
       Outstanding Stock Options granted hereunder at one time or in
       installments of 100 Stock Options (or in the whole number of unexercised
       Stock Options in which the Participant is vested, if such number is less
       than 100) by notice to the Administrator, Long-Term Incentive Plans,
       Viacom Inc., 1515 Broadway, New York, New York 10036, or to such agent(s)
       for the Company ("Agent") as the Company may from time to time specify,
       in such manner and at such address as may be specified from time to time
       by the Company. Such notice shall (i) state the number of full Stock
       Options being exercised, and (ii) be signed (or otherwise authorized in a
       manner acceptable to the Company) by the person or persons so exercising
       the Stock Options and, in the event the Stock Options are being exercised
       (pursuant to Section 1.2(c)(i) hereof) by any person or persons other
       than the Participant accompanied by proof satisfactory to the Company's
       counsel of the right of such person or persons to exercise the Stock
       Options. Information concerning any Agent and its address may be obtained
       by contacting the Administrator, Long-Term Incentive Plans.

              (b) Payment of Aggregate Option Price. Full payment of the
       aggregate Exercise Price which shall be determined by multiplying the
       number of Stock Options being exercised by the Exercise Price shall be
       made on or before the settlement date for the shares of Class B Common
       Stock issued pursuant to the exercise of the Stock Options. Such Exercise
       Price shall be paid in cash (e.g. personal bank check, certified check or
       official bank check). In addition, in accordance with Section 4.3 hereof,
       the Participant shall make an arrangement acceptable to the Company to
       pay to the Company an amount sufficient to satisfy the combined federal,
       state and local withholding tax obligations which arise in connection
       with the exercise of such Stock Options.

              (c) Issuance of Share Certificates. Upon satisfaction of the
       conditions set forth in Section 1.3(b) hereof, the Company shall deliver
       (or cause to be delivered) a certificate or certificates for the shares
       of Class B Common Stock issued pursuant to the exercise of the Stock
       Options to the Participant.

              (d) Outstanding Stock Options. The number of shares of Class B
       Common Stock subject to the Stock Options that is set forth on the Stock
       Option Certificate attached hereto or provided simultaneously online may
       not reflect the number of Outstanding Stock Options due to Stock Option
       exercises or adjustments pursuant to Article II.


                                   ARTICLE II

                       EFFECT OF CERTAIN CORPORATE CHANGES


              In the event of a merger, consolidation, stock split, dividend,
distribution, combination, reclassification or recapitalization that changes the
character or amount of the Class B Common Stock or any other changes in the
corporate structure, equity securities or capital structure of the Company, the
Committee shall make such adjustments to the number of shares of Class B Common
Stock subject to the Stock Options or the exercise price of the Stock Options,
in each case, as it deems appropriate. The Board may, in its sole discretion,
also make such other adjustments as it deems appropriate in order to preserve
the benefits or potential benefits intended to be made available hereunder. Such
determinations shall be conclusive and binding for all purposes.

                                  MISCELLANEOUS


              Section 4.1 No Rights to Grants or Continued Employment. Neither
the Certificate, the Plan nor any action taken in accordance with such documents
shall confer upon the Participant any right to be employed by the Company or any
Subsidiary thereof, nor to be entitled to any remuneration or benefits not set
forth in the Plan or the Certificate, including the right to receive any future
grants under the Plan or any other plan of the Company or any Subsidiary thereof
or interfere with or limit the right of the Company or any Subsidiary thereof to
modify the terms of or terminate the Participant's employment at any time.

              Section 4.2 Restriction on Transfer. The rights of the Participant
with respect to the Stock Options shall not be transferable by the Participant
except (i) by will or the laws of descent and distribution or (ii) subject to
the prior approval of the Committee, for transfers to members of the
Participant's immediate family or trusts whose beneficiaries are members of the
Participant's immediate family, in each case subject to the condition that the
Committee shall be satisfied that such transfer is being made for estate and/or
tax planning purposes without consideration being received therefor and subject
to such other conditions as the Committee may impose.

              Section 4.3 Tax Withholding. As a condition to the exercise of the
Stock Options, the Participant shall make a payment in cash equal to the amount
of any federal, state, local or other taxes owed as a result of such exercise.

until share certificates are delivered to the Participant upon exercise of a
Stock Option.

              Section 4.5 No Restriction on Right of Company to Effect Corporate

recapitalizations, reorganizations or other changes in the Company's capital
structure or its business, or any merger or consolidation of the Company, or any
issue of stock or of options, warrants or rights to purchase stock or of bonds,
debentures, preferred or prior preference stocks whose rights are superior to or
affect the Class B Common Stock or the rights thereof or which are convertible

of the Company, or any sale or transfer of all or any part of its assets or
business, or any other corporate act or proceeding, whether of a similar
character or otherwise.

              Section 4.6 Interpretation. In the event of a conflict or
ambiguity between the provisions of the Certificate and the provisions of any
employment agreement applicable to the Participant with respect to the Stock
Options, the provisions of such employment agreement shall be deemed controlling
to the extent such provisions are consistent with the provisions of the Plan and
are more favorable to the Participant than the provisions of the Certificate.

              Section 4.7 Breach of Covenants. In the event that the Committee
makes a good faith determination that the Participant committed a material
breach of the restrictive covenants relating to non-competition, no solicitation
of employees, confidential information or proprietary property in any employment
or other agreement applicable to the Participant during the one year period
after termination of the Participant's employment with the Company or a
Subsidiary, the Participant will be required to return any "gain" (as defined
below) realized on the Stock Options during the one year period prior to such
breach or at any time after such breach occurs. In addition, if the Committee
makes such determination, the Participant's Outstanding Stock Options will be
terminated. The "gain" on the Stock Options shall mean the difference between
the Fair Market Value and the exercise price of the Stock Options on date of
exercise.

              Section 4.8 Headings. The headings of articles and sections herein
are included solely for convenience of reference and shall not affect the
meaning of any of the provisions of the Certificate.

              Section 4.9 Governing Law. The Certificate and all rights
hereunder shall be construed in accordance with and governed by the laws of the
State of Delaware.
