SECTION 3.1  Guarantee.

         The Guarantor hereby fully and unconditionally guarantees to each
Holder the due and punctual payment of the Redemption Price or Liquidation
Distribution, as applicable, (without duplication of amounts theretofore paid by
the Issuer) when and as the same shall become due and payable, according to the

                                       3
<PAGE>


have or assert. In case of the failure of the Issuer or any successor thereto
punctually to pay any such Redemption Price or Liquidation Distribution, as
applicable, the Guarantor hereby agrees to cause any such payment to be made
punctually when and as the same shall become due and payable, as if such payment
were made by the Issuer. The Guarantor's obligation to make a Guarantee Payment
may be satisfied by direct payment of the required amounts by the Guarantor to
the Holders or by payment by the Issuer of such amounts to the Holders.


SECTION 3.2  Waiver of Notice.

         The Guarantor hereby waives notice of acceptance of this Guarantee
Agreement and of any liability to which it applies or may apply, presentment,
demand for payment, any right to require a proceeding first against the Issuer
or any other Person before proceeding against the Guarantor, protest, notice of
nonpayment, notice of dishonor, notice of redemption and all other notices and
demands.


SECTION 3.3  Obligations Not Affected.

         The Guarantor hereby agrees that its obligations under this Guarantee
Agreement 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 any Preferred Stock, the
absence of any action to enforce the same, any waiver or consent by the Holder
of any shares of Preferred Stock with respect to any terms thereof, the recovery
of any judgment against the Issuer or any action to enforce the same, or any
circumstance which might otherwise constitute a legal or equitable discharge or
defense of a guarantor. The Guarantor acknowledges that its obligations
hereunder are independent of the obligations of the Issuer with respect to the
Preferred Stock and that the Guarantor shall be liable as principal and as
debtor hereunder to make Guarantee Payments pursuant to the terms of this
Guarantee Agreement notwithstanding the occurrence of any event referred to in
this Section 3.3.


SECTION 3.4  Enforcement of Guarantee.

         Any Holder of Preferred Stock may institute a legal proceeding directly
against the Guarantor to enforce its rights under this Guarantee Agreement,
without first instituting a legal proceeding against the Issuer or any other
Person.


SECTION 3.5  Guarantee of Payment.

         This Guarantee Agreement creates a guarantee of payment and not merely
of collection. This Guarantee Agreement will not be discharged except by payment

theretofore paid by the Issuer) by the Guarantor.

         The Guarantor shall be subrogated to all (if any) rights of the Holders
against the Issuer in respect of any amounts paid by the Guarantor to the
Holders by the Guarantor under this Guarantee Agreement; provided, however, that
the Guarantor shall not (except to the extent required by mandatory provisions
of law) be entitled to enforce or exercise any rights which it may acquire by
way of subrogation or any indemnity, reimbursement or other agreement, in all
cases as a result of payment under this Guarantee Agreement, if, at the time of
any such payment, any amounts are due and unpaid under this Guarantee Agreement.
If any amount shall be paid to the Guarantor in violation of the preceding
sentence, the Guarantor agrees to hold such amount in trust for the Holders and
to pay over such amount to the Holders.

SECTION 3.7  Reinstatement of Obligations.

         If any Holder of Preferred Stock is required by any court or otherwise
to return to the Issuer or the Guarantor, or any custodian, receiver,
liquidator, assignee, trustee, sequestrator or similar official acting in
relation to the Issuer or the Guarantor, any amount paid to such Holder in
respect of such Preferred Stock, the guarantee issued under this Guarantee
Agreement, to the extend theretofore discharged, shall be reinstated in full
force and effect.


SECTION 3.8  Limitation of Guarantor's Liability.

         The Guarantor, and by its acceptance of the Preferred Stock each
Holder, hereby confirms that it is the intention of all such parties that in no
event shall any obligations of the Guarantor under the Preferred Stock
Guarantees constitute or result in a fraudulent transfer or conveyance for
purposes of, or result in a violation of, any Unites States federal, or
applicable United States state, fraudulent transfer or conveyance or similar
law. To effectuate the foregoing intention, in the event that the obligations of
the Guarantor under this Guarantee Agreement, would, but for this sentence,
constitute a fraudulent transfer or conveyance or violation, then the liability
of the Guarantor under this Guarantee Agreement 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.


SECTION 3.9  Form of Guarantee.

         The Guarantees to be endorsed upon the Preferred Stock shall be in
substantially the form set forth in Exhibit A attached hereto, with such
appropriate insertions, omissions, substitutions, and other variations as are
required or permitted hereby, and may include such letters, numbers or other
marks of identification and legends as may be required to comply with the rules
of any securities exchange or as may, consistently herewith, be determined by
the officers executing such Guarantees, as evidenced by their execution of such
Guarantees.

         The definitive Guarantees to be endorsed upon the Preferred Stock shall
be printed,

                                       5
<PAGE>

lithographed or engraved or produced by any combination of these methods on
steel engraved borders or may be produced in any other manner provided that such
manner is permitted by the rules of any securities exchange on which the
Preferred Stock may be listed, all as determined by the officers executing the
Guarantees, as evidenced by their execution of such Guarantees.


                                   ARTICLE IV

                    LIMITATION OF TRANSACTIONS; SUBORDINATION

SECTION 4.1  Limitation of Transactions.

         So long as any shares of Preferred Stock remain outstanding, the
Guarantor will not declare or pay dividends on, or redeem, purchase, acquire or
make a distribution or liquidation payment with respect to, any of its common
stock or preferred stock or make any guarantee payment with respect thereto if
at such time the Guarantor shall be in default with respect to its Guarantee
Payments or other payment obligations hereunder; provided that (a) the Guarantor
will be permitted to pay accrued dividends (and cash in lieu of fractional
shares) upon the conversion of any preferred stock of the Guarantor as may be
outstanding from time to time, in each case in accordance with the terms of such
stock and (b) the foregoing will not apply to any stock dividends paid by the
Guarantor.


SECTION 4.2  Subordination.

         This Guarantee Agreement will constitute an unsecured obligation of the
Guarantor and will rank (i) subordinate and junior in right of payment to all
other liabilities of the Guarantor, except those made pari passu or subordinate
by their terms, and (ii) senior to all capital stock now or hereafter issued by
the Guarantor and to any guarantee now or hereafter entered into by the
Guarantor in respect of any of its capital stock. The Guarantor's obligations
under this Guarantee Agreement will rank pari passu with respect to obligations
under other guarantee agreements which it may enter into from time to time to
the extent that such agreements shall be entered into in substantially the form
hereof and provide for comparable guarantees by the Guarantor of payment on
preferred stock issued by Viacom or any of its Affiliates.



                                    ARTICLE V

                                   TERMINATION


SECTION 5.1  Termination.

         This Guarantee Agreement shall terminate and be of no further force and
effect upon full payment of the Redemption Price of all Preferred stock, or upon
the distribution of Common

                                       6
<PAGE>

Stock in exchange for all of the Preferred Stock, or upon full payment of the
amounts payable in accordance with the Certificate of Designation upon
liquidation of the Issuer. Notwithstanding the foregoing, this Guarantee
Agreement will continue to be effective or will be reinstated, as the case may
be, if at any time any Holder must restore payment of any sums paid with respect
to the Preferred Stock or this Guarantee Agreement.


                                   ARTICLE VI

                                  MISCELLANEOUS

SECTION 6.1  Successors and Assigns.

         All guarantees and agreements contained in this Guarantee Agreement
shall bind the successors, assignees, receivers, trustees and representatives of
the Guarantor and shall inure to the benefit of the Holders of shares of the
Preferred Stock then outstanding. Except in connection with a consolidation,
merger or sale involving the Guarantor in which the resulting entity agrees in
writing to be legally responsible for the guarantees issued under this Guarantee
Agreement, the Guarantor shall not assign its obligations hereunder.


SECTION 6.2  Amendments.

         Except with respect to any changes which do not adversely affect the
rights of Holders (in which case no consent of Holders will be required), this
Guarantee Agreement may only be amended with the prior approval of the Holders
of not less than 66-2/3% of the Preferred Stock. The provisions of the
Certificate of Designation concerning meetings of Holders shall apply to the
giving of such approval.

                                FORM OF GUARANTEE


         For value received, Viacom International Inc., a Delaware corporation
(the "Guarantor") hereby fully and unconditionally guarantees to each Holder the
due and punctual payment of the Redemption Price or Liquidation Distribution, as
applicable, (without duplication of amounts theretofore paid by the Issuer) when
and as the same shall become due and payable, according to the terms of the
Preferred Stock, as set forth in the Certificate of Designation, regardless of
any defense, right of set-off or counterclaim which the Issuer may have or
assert. In case of the failure of the Issuer or any successor thereto punctually
to pay any such Redemption Price or Liquidation Distribution, as applicable, the
Guarantor hereby agrees to cause any such payment to be made punctually when and
as the same shall become due and payable, as if such payment were made by the
Issuer. The Guarantor's obligation to make a Guarantee Payment may be satisfied
by direct payment of the required amounts by the Guarantor to the Holders or by
payment by the Issuer of such amounts to the Holders.

         The Guarantor hereby waives notice of acceptance of this Guarantee
Agreement and of any liability to which it applies or may apply, presentment,
demand for payment, any right to require a proceeding first against the Issuer
or any other Person before proceeding against the Guarantor, protest, notice of
nonpayment, notice of dishonor, notice of redemption and all other notices and
demands.

      The Guarantor hereby agrees that its obligations under this Guarantee
Agreement 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 any Preferred Stock, the
absence of any action to enforce the same, any waiver or consent by the Holder
of any shares of Preferred Stock with respect to any terms thereof, the recovery
of any judgment against the Issuer or any action to enforce the same, or any
circumstance which might otherwise constitute a legal or equitable discharge or
defense of a guarantor. The Guarantor acknowledges that its obligations
hereunder are independent of the obligations of the Issuer with respect to the
Preferred Stock and that the Guarantor shall be liable as principal and as
debtor hereunder to make Guarantee Payments pursuant to the terms of this
Guarantee Agreement notwithstanding the occurrence of any event referred to in
this Section 3.3.

         Any Holder of Preferred Stock may institute a legal proceeding directly
against the Guarantor to enforce its rights under this Guarantee Agreement,
without first instituting a legal proceeding against the Issuer or any other
Person.

         This Guarantee Agreement creates a guarantee of payment and not merely
of collection. This Guarantee Agreement will not be discharged except by payment
of the: (i) Redemption Price or Liquidation Amount, as applicable, in full by
the Issuer, or (ii) Guarantee Payments in full (without duplication of amounts

<PAGE>

         The Guarantor shall be subrogated to all (if any) rights of the Holders
against the Issuer in respect of any amounts paid by the Guarantor to the
Holders by the Guarantor under this Guarantee Agreement; provided, however, that
the Guarantor shall not (except to the extent required by mandatory provisions
of law) be entitled to enforce or exercise any rights which it may acquire by
way of subrogation or any indemnity, reimbursement or other agreement, in all
cases as a result of payment under this Guarantee Agreement, if, at the time of
any such payment, any amounts are due and unpaid under this Guarantee Agreement.
If any amount shall be paid to the Guarantor in violation of the preceding
sentence, the Guarantor agrees to hold such amount in trust for the Holders and
to pay over such amount to the Holders.

         If any Holder of Preferred Stock is required by any court or otherwise
to return to the Issuer or the Guarantor, or any custodian, receiver,
liquidator, assignee, trustee, sequestrator or similar official acting in
relation to the Issuer or the Guarantor, any amount paid to such Holder in
respect of such Preferred Stock, the guarantee issued under this Guarantee
Agreement, to the extend theretofore discharged, shall be reinstated in full
force and effect.

         The Guarantor, and by its acceptance of the Preferred Stock each
Holder, hereby confirms that it is the intention of all such parties that in no
event shall any obligations of the Guarantor under the Preferred Stock
Guarantees constitute or result in a fraudulent transfer or conveyance for
purposes of, or result in a violation of, any Unites States federal, or
applicable United States state, fraudulent transfer or conveyance or similar
law. To effectuate the foregoing intention, in the event that the obligations of
the Guarantor under this Guarantee Agreement, would, but for this sentence,
constitute a fraudulent transfer or conveyance or violation, then the liability
of the Guarantor under this Guarantee Agreement 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.

         All terms used in this Guarantee that are defined in the Preferred
Stock Guarantee Agreement to which this Guarantee relates shall have the
meanings assigned to them in such Preferred Stock Guarantee Agreement.

         This Guarantee shall not be valid or obligatory for any purpose unless
and until the Preferred Stock to which this Guarantee relates is duly
authorized, issued and outstanding.

         Reference is made to the Preferred Stock Guarantee Agreement for
further provisions with respect to this Guarantee.

THIS GUARANTEE AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED AND INTERPRETED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK (WITHOUT REGARD TO PRINCIPLES
OF CONFLICTS OF LAWS).
