occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture.



                                        3

affected under the Indenture at any time by the Company, the Guarantor and the
Trustee with the consent of the Holders of not less than a majority in principal
amount of the Outstanding Securities of each series affected thereby.  The
Indenture also contains provisions permitting the Holders of not less than
specified percentages in aggregate principal amount of the Outstanding
Securities of each series, on behalf of the Holders of all the Securities of
such series, to waive compliance by the Company and the Guarantor with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences.  Any such consent or waiver by or on behalf of the Holder of
this Security shall be conclusive and binding upon such Holder and upon all
future Holders of this Security and of any Security issued upon the registration
of transfer hereof or in exchange herefor or in lieu hereof whether or not
notation of such consent or waiver is made upon this Security.

          As set forth in, and subject to, the provisions of the Indenture, no
Holder of any Security of this series will have any right to institute any
proceeding with respect to the Indenture or for any remedy thereunder, unless
such Holder shall have previously given to the Trustee written notice of a
continuing Event of Default with respect to this series, the Holders of not less
than 25% in principal amount of the Outstanding Securities of this series shall
have made written request, and offered reasonable indemnity, to the Trustee to
institute such proceeding as trustee, and the Trustee shall not have received
from the Holders of a majority in principal amount of the Outstanding Securities
of this series a direction inconsistent with such request and shall have failed
to institute such proceeding within 60 days; provided however, that such
limitations do not apply to a suit instituted by the Holder hereof for the
enforcement of payment of the principal of or interest on this Security on or
after the respective due dates expressed herein.

          No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of and interest on this
Security at the times, place, and rate, and in the coin or currency, herein
prescribed.

therein set forth, the transfer of this Security is registerable on the Security

transfer at the office or agency of the Company maintained for such purpose in
Boston, Massachusetts or at such other office or agency as the Company may
designate, duly endorsed by, or accompanied by a written instrument of transfer
in form satisfactory to the Company and the Security Registrar duly executed by,
the Holder hereof or his attorney duly authorized in writing, and thereupon one
or more new Securities of this series of authorized denominations and for the
same aggregate principal amount, will be issued to the designated transferee or
transferees.

          The Securities of this series are issuable only in registered form
without coupons in denominations of $1,000 and any integral multiple thereof. 
As provided in the Indenture and subject to certain limitations therein set

          No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge payable in connection therewith.

          Prior to the time of due presentment of this Security for registration
of transfer, the Company, the Guarantor, the Trustee and any agent of the
Company, the Guarantor or the Trustee may treat the Person in whose name this
Security is registered as the absolute owner hereof for all purposes, whether or
not this Security be overdue, and none of the Company, the Guarantor, the
Trustee or any agent of the Company, the Guarantor or the Trustee shall be
affected by notice to the contrary.

          If at any time, (i) the Depository is at any time unwilling or unable
to continue as Depository and a successor Depository is not appointed by the
Company within 90 days, or (ii) the Company determines that the Securities shall
no longer be represented by a global Security or Securities, then the Company
will execute and the Trustee will authenticate and deliver Securities in
definitive registered form, in authorized denominations, and in an aggregate
principal amount equal to the principal amount of this Security in exchange for
this Security.  Such Securities in definitive registered form shall be
registered in such names and issued in such authorized denominations as the
Depository, pursuant to instructions from its direct or indirect participants or
otherwise, shall instruct the Trustee.  The Trustee shall deliver such
Securities to the Persons in whose names such Securities are so registered.

          Unless the certificate of authentication hereon has been duly executed
by or on behalf of State Street Bank and Trust Company, the Trustee under the
Indenture, or its successor thereunder, by the manual signature of one of its
authorized officers, this Security shall not be entitled to any benefit under
the Indenture, or be valid or obligatory for any purpose.

          This Security shall be governed by, and construed in accordance with,
the laws of the State of New York.

                     GUARANTEE OF VIACOM INTERNATIONAL INC.


          FOR VALUE RECEIVED, VIACOM INTERNATIONAL INC., a corporation duly
organized and existing under the laws of the State of Delaware (herein called
the "Guarantor", which term includes any successor corporation under the
Indenture referred to in the Security upon which this Guarantee is endorsed),
hereby fully and unconditionally guarantees to the holder of the Security upon
which this Guarantee is endorsed the due and punctual payment of the principal
of and interest (including, in case of default, interest on principal and, to
the extent permitted by applicable law, on overdue interest), if any, on this
Security, when and as the same shall become due and payable, whether at Stated
Maturity, upon redemption, upon declaration of acceleration or otherwise,
according to the terms thereof and of the Indenture referred to therein.  In
case of the failure of Viacom Inc. or any successor thereto (herein called the
"Company") punctually to pay any such principal or interest, the Guarantor
hereby agrees to cause any such payment to be made punctually when and as the
same shall become due and payable, whether at Stated Maturity, upon redemption,
upon declaration of acceleration or otherwise, as if such payment were made by
the Company.

          The Guarantor hereby agrees that its obligations hereunder shall be as
if it were principal debtor and not merely surety, and shall be absolute and
unconditional, irrespective of the identity of the Company, the validity,
regularity or enforceability of this Security or said Indenture, the absence of
any action to enforce the same, any waiver or consent by the Holder of this
Security with respect to any provisions thereof, the recovery of any judgment
against the Company or any action to enforce the same, or any other circumstance
which might otherwise constitute a legal or equitable discharge or defense of a
guarantor.  The Guarantor hereby waives diligence, presentment, demand of
payment, filing of claims with a court in the event of insolvency or bankruptcy
of the Company, any right to require a proceeding first against the Company,
protest, notice and all demands whatsoever and covenants that this Guarantee
will not be discharged except by complete performance of the obligations
contained in this Security and in this Guarantee.

          The Guarantor shall be subrogated to all rights of the Holder of this
Security against the Company in respect of any amounts paid by the Guarantor
pursuant to the provisions of this Guarantee or the Indenture referred to in
this Security; provided however, that the Guarantor shall not be entitled to
enforce or to receive any payment arising out of, or based upon, such right of
subrogation until the principal of and interest on all Securities of the series
of which the Security upon which this Guarantee is endorsed constitutes a part
shall have been indefeasibly paid in full.

          The Indenture provides that in the event that this Guarantee would
constitute or result in a fraudulent transfer or conveyance for purposes of, or
result in a violation of, any United States federal, or applicable United States
state, fraudulent transfer or conveyance or similar law, then the liability of
the Guarantor hereunder shall be reduced to the extent necessary to eliminate
such fraudulent transfer or conveyance or violation under the applicable
fraudulent transfer or conveyance or similar law.          





                                        8

          If the Trustee or the Holder of the Security upon which this Guarantee
is endorsed is required by any court or otherwise to return to the Company or
the Guarantor, or any custodian, receiver, liquidator, assignee, trustee,
sequestrator or other similar official acting in relation to the Company or the
Guarantor, any amount paid to the Trustee or such Holder in respect of the
Security upon which this Guarantee is endorsed, this Guarantee, to the extent
theretofore discharged, shall be reinstated in full force and effect.  The
Guarantor further agrees, to the fullest extent that it may lawfully do so,
that, as between the Guarantor, on the one hand, and the Holders and the
Trustee, on the other hand, the maturity of the obligations guaranteed hereby
may be accelerated as provided in Article Five of the Indenture for the purposes
of this Guarantee, notwithstanding any stay, injunction or other prohibition
extant under any applicable bankruptcy law preventing such acceleration in
respect of the obligations guaranteed hereby.

          This Guarantee shall be governed by, and construed in accordance with,
the laws of the State of New York.

          Subject to the next following paragraph, the Guarantor hereby
certifies and warrants that all acts, conditions and things required to be done
and performed and to have happened precedent to the creation and issuance of
this Guarantee and to constitute the same valid obligation of the Guarantor have
been done and performed and have happened in due compliance with all applicable
laws.

          This Guarantee shall not be valid or become obligatory for any purpose
until the certificate of authentication on the Security upon which this
Guarantee is endorsed has been signed by the Trustee under the Indenture
referred to in this Security.

          IN WITNESS WHEREOF, the Guarantor has caused this Guarantee to be
signed by its Chairman of the Board, or its Vice Chairman of the Board, or its
President, or one of its Executive Vice Presidents or Vice Presidents, or by its
Treasurer or one of its Assistant Treasurers and attested by its Secretary or
one of its Assistant Secretaries, manually or in facsimile.

          Viacom Inc., a Delaware corporation (herein called the "Company",
which term includes any successor Person under the Indenture hereinafter
referred to), for value received, hereby promises to pay to _________, or
registered assigns, the principal sum of ___________________ on January 15, 2016

thereon on July 15, 1996 and semi-annually thereafter, on January 15 and July 15
in each year, from December 15, 1995, or from the most recent Interest Payment
Date to which interest has been paid or duly provided for, at the rate of 7.625%
per annum, until the principal hereof is paid or duly provided for, and (to the
extent lawful) to pay on demand interest on any overdue interest at the rate
borne by the Securities from the date on which such overdue interest becomes
payable to the date payment of such interest has been made or duly provided for.
The interest so payable, and punctually paid or duly provided for, on any
Interest Payment Date will, as provided in such Indenture, be paid, in
immediately available funds, to the Person in whose name this Security (or one

and (to the extent lawful) interest on such defaulted interest at the rate borne
by the Securities, may be paid to the Person in whose name this Security (or one
or more Predecessor Securities) is registered at the close of business on a
Special Record Date for the payment of such Defaulted Interest to be fixed by
the Trustee, notice whereof shall be given to Holders of Securities not less

any other lawful manner not inconsistent with the requirements of any securities

Payment of the principal of and interest on this Security will be made at the
Corporate Trust Office of the Trustee or such other office or agency of the
Company as may be designated for such purpose, in such coin or currency of the

Securities of each series, on behalf of the Holders of all the Securities of
such series, to waive compliance by the Company and the Guarantor with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences.  Any such consent or waiver by or on behalf of the Holder of
this Security shall be conclusive and binding upon such Holder and upon all
future Holders of this Security and of any Security issued upon the registration
of transfer hereof or in exchange herefor or in lieu hereof whether or not
notation of such consent or waiver is made upon this Security.

          As set forth in, and subject to, the provisions of the Indenture, no
Holder of any Security of this series will have any right to institute any
proceeding with respect to the Indenture or for any remedy thereunder, unless
such Holder shall have previously given to the Trustee written notice of a
continuing Event of Default with respect to this series, the Holders of not less
than 25% in principal amount of the Outstanding Securities of this series shall
have made written request, and offered reasonable indemnity, to the Trustee to

of this series a direction inconsistent with such request and shall have failed
to institute such proceeding within 60 days; provided however, that such
limitations do not apply to a suit instituted by the Holder hereof for the
enforcement of payment of the principal of or interest on this Security on or
after the respective due dates expressed herein.

          No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of and interest on this
Security at the times, place, and rate, and in the coin or currency, herein
prescribed.

Trustee or any agent of the Company, the Guarantor or the Trustee shall be
affected by notice to the contrary.

to continue as Depository and a successor Depository is not appointed by the
Company within 90 days, or (ii) the Company determines that the Securities shall
no longer be represented by a global Security or Securities, then the Company

principal amount equal to the principal amount of this Security in exchange for
this Security.  Such Securities in definitive registered form shall be
registered in such names and issued in such authorized denominations as the
Depository, pursuant to instructions from its direct or indirect participants or
otherwise, shall instruct the Trustee.  The Trustee shall deliver such
Securities to the Persons in whose names such Securities are so registered.

          Unless the certificate of authentication hereon has been duly executed
by or on behalf of State Street Bank and Trust Company, the Trustee under the
Indenture, or its successor thereunder, by the manual signature of one of its
authorized officers, this Security shall not be entitled to any benefit under
the Indenture, or be valid or obligatory for any purpose.

the laws of the State of New York.
