Exhibit 4.2

                                    DEBENTURE


          Unless this certificate is presented by an authorized representative
of The Depository Trust Company, a New York corporation ("DTC"), to the Company
(as defined below) or its agent for registration of transfer, exchange or
payment, and any certificate issued is registered in the name of Cede & Co. or
such other name as is requested by an authorized representative of DTC (and any
payment is made to Cede & Co. or to such other entity as is requested by an
authorized representative of DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR
VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL, since the registered owner
hereof, Cede & Co., has an interest herein.

          This Security is a global Security within the meaning of the Indenture
(as defined below) and is registered in the name of the Depositary or a nominee
of the Depositary. This Security is exchangeable for Securities registered in
the name of a person other than the Depositary or its nominee only in the
limited circumstances described in the Indenture. Unless and until this
certificate is exchanged in whole or in part for Securities in definitive
registered form in accordance with the provisions of the Indenture applicable to
such exchange, this certificate may not be transferred except as a whole by the
Depositary to a nominee of the Depositary or by a nominee of the Depositary to
the Depositary or another nominee of the Depositary or by the Depositary or any
such nominee to a successor Depositary or a nominee of such successor
Depositary.

                                                                    $450,000,000

                                                             CUSIP:  925524 AV 2

          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 Cede & Co., or
registered assigns, the principal sum of $450,000,000 on May 15, 2033 at the
office or agency of the Company referred to below, and to pay interest thereon
on November 15, 2003 and semi-annually in arrears thereafter, on May 15 and
November 15 of each year (each, an "Interest Payment Date"), from May 14, 2003,
or from the most recent Interest Payment Date to which interest has been paid or
duly provided for, at the rate of 5.50% per annum, until the principal hereof is
paid 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
or more Predecessor Securities) is registered at the close of business on the
Regular Record Date for such interest, which shall be May 1 and November 1, as
the case may be, preceding such Interest Payment Date. Any such interest not so
punctually paid or duly provided for shall forthwith cease to be payable to the
Holder on such Regular Record Date, and such Defaulted Interest, 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 than 10 days prior to such Special
Record Date, or may be paid at any time in any other lawful manner, all as more
fully provided in said Indenture.

          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 United States of America as at the time of payment is legal tender for
payment of public and private debts; provided however, that each installment of
interest and principal on this Security may at the Company's option be paid by
check to the payee or in immediately available funds by transfer to an account
maintained by the payee located in the United States.

          Any payment of principal or interest required to be made on a day that
is not a Business Day need not be made on such day, but may be made on the next
succeeding Business Day and no interest shall accrue as a result of such delayed
payment. For purposes of this Security, "Business Day" means any day that is not
a Saturday or Sunday and that, in The City of New York, is not a day on which
banking institutions are generally authorized or obligated by law or executive
order to close.

          General. This Security is one of a duly authorized issue of securities
of the Company (herein called the "Securities"), unlimited in aggregate
principal amount, issued and to be issued in one or more series under an
indenture dated as of June 22, 2001 among the Company, Viacom International
Inc., as guarantor (the "Guarantor") and The Bank of New York, as trustee
(herein called the "Trustee", which term includes any successor trustee under
the Indenture) (the "Indenture"), to which Indenture and the respective



resolutions of the Company's board of directors or resolutions pursuant to the
authority of the board of directors, an Officer's Certificate and/or indentures
supplemental thereto, as the case may be, reference is hereby made for a
statement of the respective rights, limitations of rights, duties, obligations
and immunities thereunder of the Company, the Trustee and the Holders of the
Securities, and of the terms upon which the Securities are, and are to be,
authenticated and delivered. This Security is one of a series designated as
5.50% Senior Debentures due 2033, initially limited in aggregate principal
amount to $450,000,000. This Security is a global Security representing
$450,000,000 of the Securities.

          Authorized Denominations. The Securities of this series are issuable
only in registered form without coupons in denominations of not less than $1,000
and any integral multiple thereof.

          Book-Entry Security. This Security is a "book-entry" Security and is
being registered in the name of Cede & Co., as nominee of The Depository Trust
Company ("DTC"). Subject to the terms of the Indenture, this Security will be
held by DTC or its nominee, and beneficial interests will be held by beneficial
owners through the book-entry facilities of DTC or its nominee in denominations
of not less than $1,000 and integral multiples thereof. As long as this Security
is registered in the name of DTC or its nominee, the Trustee will make payments
of principal of and interest on this Security by wire transfer of immediately
available funds to DTC or its nominee. Notwithstanding the above, upon the
maturity of this Security, the principal, together with accrued interest
thereon, will be paid in immediately available funds upon surrender of this
Security at the Corporate Trust Office of the Trustee or such other offices or
agencies appointed by the Trustee for that purpose or such other locations
provided in the Indenture.

          Event of Default. If an Event of Default with respect to Securities of
this series shall 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.

          Sinking Fund. The Securities of this series are not subject to any
sinking fund.


          Optional Redemption. The Securities of this series will be redeemable
at any time, at the option of the Company, in whole or from time to time in
part, upon not less than 30 nor more than 60 days' prior notice, on any date
prior to their maturity at a Redemption Price equal to the sum of 100% of the
principal amount thereof and the Make-Whole Amount and any accrued and unpaid
interest, to the Redemption Date (subject to the rights of holders of record on
the relevant Regular Record Date that is on or prior to the Redemption Date to
receive interest due on the relevant Interest Payment Date).

          The term "Make-Whole Amount" means, the excess, if any, of (i) the
aggregate present value as of the Redemption Date of principal being redeemed
and the amount of interest (exclusive of interest accrued to the Redemption
Date) that would have been payable if redemption had not been made, determined
by discounting, on a semiannual basis, the remaining principal and interest at
the Reinvestment Rate (determined on the third Business Day preceding the date
notice of redemption is given) from the dates on which the principal and
interest would have been payable if the redemption had not been made, to the
Redemption Date, over (ii) the aggregate principal amount of the Securities
being redeemed.

          The term "Reinvestment Rate" means 0.20% plus the arithmetic mean of
the yields under the heading "Week Ending" published in the most recent Federal
Reserve Statistical Release H.15 (or any comparable successor publication) under
the caption "Treasury Constant Maturities" for the maturity (rounded to the
nearest month) corresponding to the remaining life to maturity, as of the
maturity of the principal being redeemed or paid. If no maturity exactly
corresponds to the maturity, yields for the two published maturities most
closely corresponding to the maturity will be so calculated and the Reinvestment
Rate will be interpolated or extrapolated on a straight-line basis, rounding to
the nearest month. The most recent Federal Reserve Statistical Release H.15
published prior to the date of determination of the Make-Whole Amount will be
used for purposes of calculating the Reinvestment

                                       2



Rate.

          The Make-Whole Amount will be calculated by an independent investment
banking institution of national standing appointed by the Company. If the
Company fails to make the appointment at least 45 business days prior to the
date of redemption, or if the institution is unwilling or unable to make the
calculation, the calculation will be made by an independent investment banking
institution of national standing appointed by the Trustee.

          If the Reinvestment Rate is not available as described above, the
Reinvestment Rate will be calculated by interpolation or extrapolation of
comparable rates selected by the independent investment banking institution.

          In the case of any partial redemption, selection of the Securities of
this series for redemption will be made by the Trustee in compliance with the
requirements of the principal national securities exchange, if any, on which the
Securities of this series are listed or, if the Securities of this series are
not listed on a national securities exchange, by lot or by such other method as
the Trustee in its sole discretion shall deem to be fair and appropriate;
provided that no Securities of this series of $1,000 in principal amount or less
shall be redeemed in part. If any Security is to be redeemed in part only, the
notice of redemption relating to such Security shall state the portion of the
principal amount thereof to be redeemed. A new Security in principal amount
equal to the unredeemed portion thereof will be issued in the name of the Holder
thereof upon cancellation of the original Security.

          Defeasance and Covenant Defeasance. The Indenture contains provisions
for defeasance at any time of (a) the entire indebtedness of the Company on this
Security and (b) certain restrictive covenants and the related Defaults and
Events of Default, upon compliance by the Company with certain conditions set
forth therein, which provisions apply to this Security.

          Modification and Waivers; Obligations of the Company Absolute. The
Indenture permits, with certain exceptions as therein provided, the amendment
thereof and the modification of the rights and obligations of the Company and
the rights of the Holders of the Securities of each series. Such amendment may
be effected 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
aggregate 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 shall be conclusive and binding
upon the Holders of this Security 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.

                                       3


          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.

          Registration of Transfer or Exchange. As provided in the Indenture and
subject to certain limitations therein set forth, the transfer of this Security
will be registered on the Security Register of the Company upon surrender of
this Security for registration of transfer at the office or agency of the
Company maintained for such purpose in New York, New York 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.

          As provided in the Indenture and subject to certain limitations
therein set forth, the Securities of this series are exchangeable for a like
aggregate principal amount of Securities of this series and of a different
authorized denomination, as requested by the Holder surrendering the same.

          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.

          This Security is a global Security. If at any time, a Depositary is at
any time unwilling or unable to continue as Depositary and a successor
Depositary is not appointed by the Company within 90 days, 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 Depositary,
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.

          Defined Terms. All terms used in this Security that are defined in the
Indenture and are not otherwise defined herein shall have the meanings assigned
to them in the Indenture.

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

          Unless the certificate of authentication hereon has been duly executed
by or on behalf of The Bank of New York, as 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.

                                       4



          IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed.

Dated: May 14, 2003






                     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.

          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.



          All terms used in this Guarantee that are defined in the Indenture and
are not otherwise defined herein shall have the meanings assigned to them in the
Indenture.

          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.

                                       2




          IN WITNESS WHEREOF, the Guarantor has caused this instrument to be
duly executed.
