and delivered by the Borrower and are legal, valid and binding obligations of

the following actions at the same or different times: (i) terminate forthwith
any of Lender's future obligations hereunder, and (ii) declare the Note and any

presentment, demand, protest or any other notice of any kind, all of which are
hereby expressly waived by the Borrower, anything contained herein or in the
Note to the contrary notwithstanding.

addition to and not in substitution for any rights or remedies provided by law;
any single partial exercise by the Lender of any right or remedy for a default
or a breach of any term, covenant, condition or agreement contained herein or in
the Note, shall not be deemed to be a waiver of or to alter, affect or prejudice
any other right or remedy or other rights or remedies to which the may be
lawfully entitled for the same default or breach.

     (c) The taking of a judgment or judgments or any other action or dealing
whatsoever by the Lender will not operate as a merger of any of the obligations
owing to the Lender or in any suspended payment or affect or prejudice the
rights, remedies and powers, legal or equitable, which the Lender may have in
connection with such obligations.

Sumner M. Redstone
New York, New York

Dear Mr. Redstone:

          Effective as of May 5, 2003 (the "Effective Date"), you will continue
to be employed as Chief Executive Officer of Viacom, Inc. ("Viacom") and serve
as Chairman of the Board of Directors of Viacom (the "Board") pursuant to the
terms of this letter agreement (the "Agreement").

          1. Duties. During your employment with Viacom, you will perform such
duties and have such responsibilities and authority as set forth hereunder:

          You, in consultation with Mel Karmazin, the President and Chief
Operating Officer of Viacom (the "COO"), will be generally responsible for
overseeing the affairs of Viacom and will have full and final-decision making
authority over corporate policy and strategy. The COO will report directly and
solely to you. You also will have the authority to overrule the COO on operating
matters, subject to the Board consultation provisions set forth below. For this
purpose, "corporate policy and strategy" means significant acquisitions,
significant dispositions, significant partnerships or ventures with other
companies, significant shareholder relations and corporate governance matters,
the entry into significant new lines of business and withdrawal from significant
existing lines of business, and other matters of comparable significance to
Viacom. The COO, in consultation with you, will have full authority over the
operations of Viacom. At any time during the term of the COO's employment, you
may recommend to the Board that the COO should be terminated. All officers,
other than you and the COO, will report directly or indirectly to the COO. The
COO will keep you advised of significant operating or organizational issues,
including, without limitation, the hiring and firing of senior executives,
provided that solely with regard to the firing of a group of senior executives
to be mutually agreed by you and the COO, and the hiring of their replacements,
you and the COO will agree jointly on such actions. The COO will ensure that you
will have full access to Viacom's executives, to staff meetings convened by the
COO, and to information and reports compiled by management so that you can fully
perform your responsibilities as Chief Executive

<PAGE>

Officer and are fully briefed on operating issues and the business of Viacom. It
is intended and expected that you will participate actively in such staff
meetings. You will have the right to overrule the COO's decision on any
operating issue only following prior consultation with the Board at a meeting
called for such purpose to provide the Board with the full opportunity to take
any action it deems appropriate with respect to such operating issue.

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

          (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
your employment with Viacom, determined and payable as follows ("Bonus"):

          (i)  Your Bonus for each of the calendar years during your employment
               with Viacom 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 for 2003 shall be $6,655,000, and for each
               calendar year thereafter shall be at least equal to the Target
               Bonus for the COO.

          (iii) Your Bonus for any calendar year shall be payable by February 28
               of the following year (even if not during your employment with
               Viacom).

          (c) Deferred Compensation: In addition to your Salary and Bonus, you
shall earn, in respect of calendar year 2003 and each calendar year thereafter
during your employment with Viacom, an additional amount ("Deferred
Compensation"), the payment of which (together with the return thereon as
provided in this paragraph 2(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 2003 shall be
$2,993,000. The amount of Deferred Compensation for each subsequent calendar
year of your employment shall be the amount of Deferred Compensation for the
preceding year increased by 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

                                       2
<PAGE>

time) is determined or, if you do not participate in such plan, with a return to
be mutually agreed by Viacom and you. Viacom's obligation to pay the Deferred
Compensation (including the return thereon provided for in this paragraph 2(c))
shall be an unfunded obligation to be satisfied from the general funds of
Viacom.

          (d) Except as expressly provided herein, your compensation shall be
determined by the Compensation Committee of the Board.

          3. 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

          10. No Implied Contract. Nothing contained in this Agreement shall be
construed to impose any obligation on Viacom to renew this Agreement or any
portion thereof. The parties intend to be bound only upon execution of a written
agreement and no negotiation, exchange of draft or partial performance shall be
deemed to imply an agreement. Neither the continuation of employment nor any
other conduct shall be deemed to imply a continuing agreement upon the
expiration of this Agreement.
