     principal of, or premium or interest on, any Indebtedness in an aggregate
     principal amount of $50,000,000 or more (excluding Indebtedness hereunder)

     maturity, required prepayment, acceleration, demand or otherwise); or any
     other event shall occur or condition shall exist under any agreement or

     extension of any grace period applicable to any such Indebtedness shall be
     taken into account for the purposes of this subsection (d) and (ii) this
     subclause (d) shall not apply to any provision that permits the holders, or
     a trustee on their behalf, to cause Indebtedness to become due prior to its
     stated maturity because of the failure to deliver to such holders or such
     trustee financial statements or certificates for any Subsidiary that is not
     required by law or regulation to file financial statements with the SEC,
     unless such Indebtedness has become due prior to its stated maturity as a
     result of such failure); or"

Dear Philippe:

                  This letter is intended to confirm certain of our
understandings relating to the Agreement between you and Viacom Inc. (the
"Company"), dated as of September 6, 1999 (the "Agreement").

                  You have agreed to resign your employment as an employee of
the Company and any of the Company's direct or indirect subsidiaries and your
position as an officer of the Company as Deputy Chairman and Executive Vice
President. You further have agreed to resign as an officer and member of the
boards of directors of the Company's direct and indirect subsidiaries (except as
noted in the following sentence). It is our mutual intention that you shall
continue as a member of the boards of directors of the Company, Blockbuster Inc.
and The MTVi Group, Inc. for the remainder of your current term. All
resignations shall be effective as of the day immediately prior to the Effective
Time of the closing of the transactions contemplated by the Agreement and Plan
of Merger between CBS Corporation and the Company, dated as of September 6,
1999. The Company acknowledges that such resignation is at the request, and for
the benefit, of the Company, shall be deemed to constitute termination of your
employment for "Good Reason" (and for this purpose the Company waives any
written notice from you or any period within which to cure) and the Resignation
Date for purposes of the Agreement shall be deemed to include the date of such
resignation thereby qualifying you for all the payments and benefits attendant
to a resignation for Good Reason or a resignation on the Resignation Date, under
the Agreement, and the Restricted Period for purposes of Section 4.1 of the
Agreement shall commence on such Resignation Date.
