         12. Miscellaneous.  Your Employment  Agreement shall be amended to add
the following  paragraphs 20 and 21 after paragraph 19 therein:

                  "20. Deductions and Withholdings, Payment of Deferred
         Compensation. All amounts payable under this Agreement shall be paid
         less deductions and income and payroll tax withholdings as may be
         required under applicable law and any property (including shares of
         Viacom Class B Common Stock), benefits and perquisites provided to you
         under this Agreement shall be taxable to you as may be required under
         applicable law. Notwithstanding any other provisions of this Agreement
         to the contrary, no payment for any restricted share units or
         distribution of any other deferred compensation shall be made sooner
         than the earliest date permitted under the provisions of the Internal
         Revenue Code or the rules or regulations promulgated thereunder, as in
         effect on the date of such payment, in order for such payment to be
         taxable at the time of the distribution thereof without imposition of
         penalty taxes under the American Jobs Creation Act of 2004.

                  21. Viacom Split. Viacom has announced that it is exploring
         the separation of Viacom into two businesses. Viacom may, in its
         discretion, assign this Agreement to the publicly held parent
         corporation of either of the two businesses. In such event, you agree
         that your covenants under paragraphs 6(a) through (i) (non-competition,
         etc.) shall apply to the benefit of both businesses until one year
         after the date of the separation and then only to the business for
         which you are employed at the time of termination of your employment.
         You further agree that it shall not be considered Good Reason or a
         breach of Viacom's obligations under this Agreement if you are assigned
         duties directly comparable to those set forth in paragraph 2 for one of
         the succeeding businesses and report to the Chairman or the CEO
         directly with a title no less than the title you had with Viacom, and
         the financial statements of the succeeding business report no less than
         30% of the consolidated revenues and OIBDA, respectively, of Viacom for
         the year ended December 31, 2004."

         Except as herein amended, all other terms and conditions of your
Employment Agreement shall remain the same and your Employment Agreement, as
herein amended, shall remain in full force and effect.
