Section 1-Registrant's Business and Operations

Item 1.01  Entry into a Material Definitive Agreement.

           Deferred Compensation Plans.

     On December 9, 2004, the Board of Directors of Viacom Inc. ("Viacom" or the
"Company")   authorized  the  future  modification  of  the  Company's  deferred
compensation  plans (the "Plans"),  including the amendment of existing plans or
adoption of new plans, to comply with the new  requirements of Internal  Revenue
Code Section 409A set forth in the American Jobs Creation Act of 2004, the final
guidance  on which is  pending.  Among the  affected  plans are the Viacom  Inc.
Deferred  Compensation  Plan for  Non-Employee  Directors,  under  which  Viacom
directors  may elect to  participate,  and the  Viacom  Excess  401(k)  Plan for
Designated  Senior  Executives  and Viacom Bonus  Deferral  Plan for  Designated
Senior  Executives,  under  which  Viacom's  executive  officers  may  elect  to
participate.  The  material  terms of the Plans,  which are exhibits to Viacom's
2003 Form 10-K, will not change except to the extent required to comply with the
requirements  of Section  409A.

     A form of election  form  relating to the  Deferred  Compensation  Plan for
Non-Employee Directors pursuant to which Viacom's directors will make their 2005
elections is attached hereto as Exhibit 10.

           Director Compensation.

     On  December  9, 2004,  the Board of  Directors  dissolved  its  Nominating
Committee,  assigning its responsibilities to the Corporate Governance Committee
and renaming that committee the  "Nominating  and Governance  Committee." All of
the members of the Nominating and Governance Committee are independent directors
under the New York Stock Exchange Corporate Governance Listing Standards.

     In addition,  the Board approved changes to the compensation for members of
its  Compensation  Committee  and set the  compensation  for  its  newly  formed
Strategic  Planning  Committee and recently  formed Ad Hoc Committee.

     Including  these December 9th actions,  the current cash  compensation  for
outside directors serving on the Viacom Board of Directors is as follows:

o    Outside directors  receive an annual retainer of $60,000,  payable in equal
     installments quarterly in advance, plus a per meeting fee of $2,000;

o    The  Chairs  of the  Audit,  Compensation,  Strategic  Planning  and Ad Hoc
     Committees  each  receive an annual  retainer of $20,000,  payable in equal
     installments  quarterly  in advance,  and the  members of those  committees
     receive a per meeting fee of $2,000; and

o    The Chair of the  Nominating and  Governance  Committee  receives an annual
     retainer of $15,000,  payable in equal  installments  quarterly in advance,
     and the members of that committee receive a per meeting fee of $1,500.





     "Outside  directors" are those members of the Viacom Board of Directors who
are not  employees of Viacom,  National  Amusements  or any of their  respective
subsidiaries, or an immediate family member of such persons. Directors may elect
to defer their cash  compensation  under the Viacom Inc.  Deferred  Compensation
Plan for Non-Employee Directors, or any successor plan.

     In addition,  as previously  disclosed,  under the terms of the Viacom Inc.
2000 Stock  Option Plan for Outside  Directors,  which is an exhibit to Viacom's
Form 10-Q for the  quarterly  period  ended  June 30,  2004,  outside  directors
automatically  receive a one-time  grant of 10,000 stock options on the date the
director  joins the Board,  which  options vest one year from the date of grant,
and an annual  grant of 4,000  stock  options on January 31 of each year,  which
options  vest in equal  installments  over a period of four years.  The exercise
price of the stock options is the closing price of Viacom's Class B common stock
on the New York  Stock  Exchange  (or such other  exchange  on which the Class B
common stock may then be listed) on the date of the stock option grant.
