Item 5.   Interests of Named Experts and Counsel.

          Michael D. Fricklas, Esq., Executive Vice President, General Counsel
and Secretary of Viacom Inc., who has rendered an opinion stating that under
applicable state law the shares of Class B Common Stock to which the
Registration Statement relates will be, when issued, validly issued, fully paid
and nonassessable. As of December 31, 2002, Mr. Fricklas held 46 shares of Class
A Common Stock and 1,188 shares of Class B Common Stock and held exercisable
options to acquire 330,416 shares of Class B Common Stock and non-exercisable
options to acquire 189,584 shares of Class B Common Stock.


Item 6.   Indemnification of Directors and Officers.

          Section 102(b)(7) of the Delaware General Corporation Law ("DGCL")
allows a corporation to include in its certificate of incorporation a provision
eliminating the personal liability of a director to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except in cases where the director breached his duty of loyalty to the
corporation or its stockholders, failed to act in good faith, engaged in
intentional misconduct or a knowing violation of the law, willfully or
negligently authorized the unlawful payment of a dividend or approved an
unlawful stock redemption or repurchase or obtained an improper personal
benefit. The Registrant's Amended and Restated Certificate of Incorporation (the
"Viacom Charter") contains provisions that eliminate directors' personal
liability, in certain circumstances.

          Section 1 of Article VI of the Viacom Charter provides that the
Registrant shall indemnify any person who was or is a party or is threatened to
be involved in any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative, by reason of the fact
that he is or was a director, officer, employee or agent of the Registrant, or
is or was serving at the request of the Registrant as a director, officer,
employee or agent (including trustee) of another corporation, partnership, joint
venture, trust or other enterprise, to the fullest extent authorized by the
DGCL, as the same exists or may hereafter be amended, against judgments, fines,
amounts paid in settlement and expenses (including attorneys' fees), actually
and reasonably incurred by him in connection with such action, suit or
proceeding. Notwithstanding the foregoing, except with respect to proceedings to
enforce rights to indemnification and advancement of expenses, the Registrant
shall indemnify an indemnitee in connection with a proceeding (or part thereof)
initiated by the indemnitee, if and only if the Board of Directors authorized
the bringing of the action, suit or proceeding (or part thereof) in advance of
the commencement of the proceeding.

          The Viacom Charter provides that to the extent that a present or
former director, officer, employee or agent of the Registrant has been
successful on the merits or otherwise in defense of any action, suit or
proceeding referred above, or in defense of any claim, issue or matter therein,
such person shall be indemnified against expenses (including attorneys' fees)
actually and reasonably incurred by that person in connection therewith. The
indemnification and advancement of expenses provided by, or granted pursuant to,
the indemnification provisions of the Viacom Charter shall not be deemed
exclusive of any other rights to which a person seeking indemnification or
advancement of expenses may be entitled under any statute, by- law, agreement,
vote of stockholders or disinterested directors or otherwise, both as to action
in that person's official capacity and as to action in another capacity while
holding such office. Without limiting the foregoing, the Registrant is
authorized to enter into an agreement with any director, officer, employee or
agent of the Registrant providing indemnification for such person against
expenses, including attorneys' fees, judgments, fines and amounts paid in
settlement that result from any threatened pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative, including
any action by or in the right of the Registrant, that arises by reason of the
fact that such person is or was a director, officer, employee or agent of the
Registrant, or is or was serving at the request of the Registrant as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, to the full extent allowed by law, except that no
such agreement shall provide for indemnification for any actions that constitute
fraud, actual dishonesty or willful misconduct.

                                     4
<PAGE>


          The Registrant may purchase and maintain insurance on behalf of any
person who is or was a director, officer, employee or agent of the Registrant,
or is or was serving at the request of the Registrant as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise against any liability asserted against him and incurred by him
in any such capacity, or arising out of his status as such, whether or not the
Registrant would have the power to indemnify him against such liability under
the provisions of Article VI of the Viacom Charter.

           Pursuant to Section 5 of Article VI of the Viacom Charter, the
Registrant has purchased certain liability insurance for its officers and
directors as permitted by Section 145(g) of the DGCL.

Item 7.   Exemption from Registration Claimed.

          Not Applicable.

Item 8.   Exhibits.

          See Exhibit Index.

Item 9.   Undertakings.

          (a) The undersigned Registrant hereby undertakes:

               (1) To file, during any period in which offers or sales are being
          made, a post-effective amendment to this registration statement to
          include any material information with respect to the plans of
          distribution not previously disclosed in this Registration Statement
          or any material change to such information in the Registration
          Statement.

               (2) That, for the purpose of determining any liability under the
          Securities Act, each such post-effective amendment shall be deemed to
          be a new registration statement relating to the securities offered
          therein, and the offering of such securities at that time shall be
          deemed to be the initial bona fide offering thereof.

               (3) To remove from registration by means of a post-effective
          amendment any of the securities being registered which remain unsold
          at the termination of the offering.

          (b) The undersigned Registrant hereby undertakes that, for purposes of
determining liability under the Securities Act, each filing of the Registrant's
annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act
that is incorporated by reference in this Registration Statement shall be deemed
to be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.

          (c) Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer, or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

                                     3
Item 5.   Interests of Named Experts and Counsel.

          Michael D. Fricklas, Esq., Executive Vice President, General Counsel
and Secretary of Viacom Inc., who has rendered an opinion stating that under
applicable state law the shares of Class B Common Stock to which the
Registration Statement relates will be, when issued, validly issued, fully paid

options to acquire 330,416 shares of Class B Common Stock and non-exercisable
options to acquire 189,584 shares of Class B Common Stock.

Item 6.   Indemnification of Directors and Officers.

          Section 102(b)(7) of the Delaware General Corporation Law ("DGCL")
allows a corporation to include in its certificate of incorporation a provision
eliminating the personal liability of a director to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except in cases where the director breached his duty of loyalty to the
corporation or its stockholders, failed to act in good faith, engaged in
intentional misconduct or a knowing violation of the law, willfully or
negligently authorized the unlawful payment of a dividend or approved an
unlawful stock redemption or repurchase or obtained an improper personal
benefit. The Registrant's Amended and Restated Certificate of Incorporation (the
"Viacom Charter") contains provisions that eliminate directors' personal
liability, in certain circumstances.

          Section 1 of Article VI of the Viacom Charter provides that the
Registrant shall indemnify any person who was or is a party or is threatened to
be involved in any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative, by reason of the fact
that he is or was a director, officer, employee or agent of the Registrant, or
is or was serving at the request of the Registrant as a director, officer,
employee or agent (including trustee) of another corporation, partnership, joint
venture, trust or other enterprise, to the fullest extent authorized by the
DGCL, as the same exists or may hereafter be amended, against judgments, fines,
amounts paid in settlement and expenses (including attorneys' fees), actually
and reasonably incurred by him in connection with such action, suit or
proceeding. Notwithstanding the foregoing, except with respect to proceedings to
enforce rights to indemnification and advancement of expenses, the Registrant
shall indemnify an indemnitee in connection with a proceeding (or part thereof)
initiated by the indemnitee, if and only if the Board of Directors authorized
the bringing of the action, suit or proceeding (or part thereof) in advance of
the commencement of the proceeding.

          The Viacom Charter provides that to the extent that a present or
former director, officer, employee or agent of the Registrant has been
successful on the merits or otherwise in defense of any action, suit or
proceeding referred above, or in defense of any claim, issue or matter therein,
such person shall be indemnified against expenses (including attorneys' fees)
actually and reasonably incurred by that person in connection therewith. The
indemnification and advancement of expenses provided by, or granted pursuant to,
the indemnification provisions of the Viacom Charter shall not be deemed
exclusive of any other rights to which a person seeking indemnification or
advancement of expenses may be entitled under any statute, by- law, agreement,
vote of stockholders or disinterested directors or otherwise, both as to action
in that person's official capacity and as to action in another capacity while
holding such office. Without limiting the foregoing, the Registrant is
authorized to enter into an agreement with any director, officer, employee or
agent of the Registrant providing indemnification for such person against
expenses, including attorneys' fees, judgments, fines and amounts paid in
settlement that result from any threatened pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative, including
any action by or in the right of the Registrant, that arises by reason of the
fact that such person is or was a director, officer, employee or agent of the
Registrant, or is or was serving at the request of the Registrant as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, to the full extent allowed by law, except that no
such agreement shall provide for indemnification for any actions that constitute
fraud, actual dishonesty or willful misconduct.

                                     4
The Registrant may purchase and maintain insurance on behalf of any
person who is or was a director, officer, employee or agent of the Registrant,
or is or was serving at the request of the Registrant as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise against any liability asserted against him and incurred by him
in any such capacity, or arising out of his status as such, whether or not the
Registrant would have the power to indemnify him against such liability under
the provisions of Article VI of the Viacom Charter.

           Pursuant to Section 5 of Article VI of the Viacom Charter, the
Registrant has purchased certain liability insurance for its officers and
directors as permitted by Section 145(g) of the DGCL.

Item 7.   Exemption from Registration Claimed.

          Not Applicable.

Item 8.   Exhibits.

          See Exhibit Index.

Item 9.   Undertakings.

          (a) The undersigned Registrant hereby undertakes:

               (1) To file, during any period in which offers or sales are being
          made, a post-effective amendment to this registration statement to
          include any material information with respect to the plans of
          distribution not previously disclosed in this Registration Statement
          or any material change to such information in the Registration
          Statement.

               (2) That, for the purpose of determining any liability under the
          Securities Act, each such post-effective amendment shall be deemed to
          be a new registration statement relating to the securities offered
          therein, and the offering of such securities at that time shall be
          deemed to be the initial bona fide offering thereof.

               (3) To remove from registration by means of a post-effective
          amendment any of the securities being registered which remain unsold
          at the termination of the offering.

          (b) The undersigned Registrant hereby undertakes that, for purposes of
determining liability under the Securities Act, each filing of the Registrant's
annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act
that is incorporated by reference in this Registration Statement shall be deemed
to be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.

          (c) Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer, or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
