% Senior Notes due 2055

The senior notes due 2055 will bear interest at % per year and will mature on , 2055. We will pay interest on the senior notes quarterly in arrears on , , and of each year, beginning , 2007. We may redeem the senior notes, in whole or in part, at any time and from time to time on or after , 2011 at a redemption price equal to 100% of the principal amount redeemed plus accrued and unpaid interest to the redemption date. If market conditions permit, we may increase the amount of senior notes we sell in this offering. The senior notes do not provide for a sinking fund. The senior notes will be unsecured senior obligations of Viacom Inc. and will rank equally with Viacom Inc.’s other existing and future unsecured senior obligations. The senior notes will be issued in minimum denominations of $25 and in multiples of $25.

Application has been made to list the senior notes on the New York Stock Exchange. We expect trading in the senior notes on the New York Stock Exchange to begin within 30 days after the original issue date. The senior notes are expected to trade “flat.” This means that purchasers will not pay, and sellers will not receive, any accrued and unpaid interest on the senior notes that is not included in the trading price. Currently there is no public market for the senior notes.

Investing in the senior notes involves risks that are described in the “ Risk Factors” sections of our Annual Report on Form 10-K for the year ended December 31, 2005 and our Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 2006, June 30, 2006 and September 30, 2006 and on page S-5 of this prospectus supplement.

Summary Unaudited Pro Forma Condensed Consolidated Financial Information

The summary unaudited pro forma condensed consolidated financial information is derived from, and should be read in conjunction with, the information under the heading “Unaudited Pro Forma Condensed Consolidated Financial Information” and the notes thereto included in this prospectus supplement beginning on page S-7. The summary unaudited pro forma condensed consolidated financial information is based upon our historical carve-out financial statements included in our annual report on Form 10-K for the year ending December 31, 2005 and in our quarterly report on Form 10-Q for the nine months ended September 30, 2006, each of which is incorporated by reference herein. This pro forma financial information is presented as if the $5.41 billion of debt incurred to remit the special dividend in connection with the separation from the former Viacom Inc., the offering of fixed rate senior notes and senior debentures we completed on April 12, 2006 and the offering of floating rate senior notes we completed on June 16, 2006, and the use of proceeds therefrom, had occurred at the beginning of the period presented. This summary unaudited pro forma condensed consolidated financial information does not give effect to the offering of the senior notes offered hereby and the use of the net proceeds therefrom. Management believes the assumptions and allocations are reasonable. However, the pro forma results do not necessarily represent what the actual results would have been had Viacom been a stand alone public company, nor are they necessarily indicative of future results.

RISK FACTORS

You should consider carefully all of the information set forth in this prospectus supplement, in the accompanying prospectus and any documents incorporated by reference herein and, in particular, the risk factors described below, described in our Annual Report on Form 10-K for the year ended December 31, 2005 and described in our quarterly reports on Form 10-Q for the quarterly periods ended March 31, 2006, June 30, 2006 and September 30, 2006. In addition, the risks described below and elsewhere in this prospectus supplement are not the only ones we are facing. The risks described below, described in our Annual Report on Form 10-K for the year ended December 31, 2005 and described in our quarterly reports on Form 10-Q for the quarterly periods ended March 31, 2006, June 30, 2006 and September 30, 2006 and incorporated by reference herein are considered to be the most material. However, there may be other unknown or unpredictable economic, business, competitive, regulatory or other factors that could have material adverse effects on our future results. Past financial performance may not be a reliable indicator of future performance and historical trends should not be used to anticipate results or trends in future periods.

The Senior Notes Will Be Structurally Subordinated to All Obligations of Our Subsidiaries

The senior notes will not be guaranteed by our subsidiaries, and therefore they will be structurally subordinated to all existing and future indebtedness and other obligations of our subsidiaries, including claims with respect to trade payables. As of September 30, 2006, our direct and indirect subsidiaries had approximately $343.3 million of indebtedness outstanding. The indenture for the senior notes will not prohibit or limit any of our subsidiaries from incurring any indebtedness or other obligations. In the event of a bankruptcy, liquidation or dissolution of a subsidiary, following payment by the subsidiary of its liabilities, the subsidiary may not have sufficient assets to make payments to us.

An Active Trading Market for the Senior Notes May Not Develop or Be Sustained

The senior notes are new securities for which there currently is no market. Although we have applied to list the senior notes on the New York Stock Exchange, we can provide no assurance as to the future development or maintenance of a market for the senior notes or the ability of holders of the senior notes to sell their senior notes. Although the underwriters have advised us that they currently intend to make a market in the senior notes after completion of the offering, they have no obligation to do so, and such market making activities may be discontinued at any time and without notice. We cannot assure you that any market for the senior notes will develop or be sustained. If an active market is not developed or sustained, the market price and liquidity of the senior notes may be adversely affected.

S-5

USE OF PROCEEDS

We estimate that the net proceeds from this offering of senior notes after deducting the underwriters’ discount and our other offering fees and expenses will be approximately $ . We intend to use these net proceeds to repay a portion of the amounts outstanding under our term credit facility due 2007, which is one of our existing credit facilities, which credit facilities were principally used to pay the preliminary special dividend made to CBS Corporation in connection with the separation from the former Viacom Inc. We have previously refinanced a portion of these outstanding borrowings through the issuance of fixed rate senior notes and senior debentures on April 12, 2006 and floating rate senior notes on June 16, 2006. Borrowing rates under our credit facilities are determined at our option at the time of each borrowing and are based generally on the prime rate in the United States or the London Interbank Offer Rate plus a margin based on our senior unsecured credit rating. We also pay a facility fee based on the total amount of the commitments under a portion of the term facility.

Affiliates of Merrill Lynch, Pierce, Fenner & Smith Incorporated, Wachovia Capital Markets, LLC, Citigroup Global Markets Inc., UBS Securities LLC and affiliates of certain of the other underwriters are lenders under our existing credit facilities, a portion of which we intend to repay with the net proceeds of this offering.

RATIO OF EARNINGS TO FIXED CHARGES

Set forth below is information concerning our ratio of earnings to fixed charges. For purposes of determining the ratio of earnings to fixed charges, earnings consist of earnings from continuing operations before income taxes plus distributed income of equity affiliates and fixed charges. Fixed charges are defined as interest expense and one-third of gross rent expense relating to operating leases, which is deemed to be representative of interest. For the nine months ended September 30, 2006, fixed charges include interest expense on indebtedness outstanding during that period. For periods ending December 31, 2005 and prior, indebtedness, other than certain capital lease obligations, was not transferred to Viacom as it remained at CBS Corporation. Accordingly, debt service cost is not reflected in periods prior to the nine months ended September 30, 2006.

Interest expense increased for the first nine months of 2006 primarily due to higher average debt outstanding and higher interest rates. The higher debt outstanding resulted principally from funding the special dividend payment made to CBS Corporation in connection with the separation from the former Viacom Inc. in December 2005, the purchase of DreamWorks L.L.C. on January 31, 2006, and the purchase of common stock under the Company’s stock repurchase program which commenced in January 2006. Interest expense will increase substantially for the remainder of 2006 versus 2005 as this higher level of debt is expected to be outstanding for the entire year.

UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION

This unaudited pro forma condensed consolidated financial information and the notes thereto should be read together with our audited consolidated financial statements and the notes thereto for the year ended December 31, 2005, and the related “Management’s Discussion and Analysis of Results of Operations and Financial Condition,” in our annual report on Form 10-K for the year ended December 31, 2005, and in our quarterly report on Form 10-Q for the nine months ended September 30, 2006, each of which is incorporated by reference herein. This pro forma financial information is presented as if the $5.41 billion of debt incurred to remit the special dividend in connection with the separation from the former Viacom Inc., the offering of fixed rate senior notes and senior debentures we completed on April 12, 2006 and the offering of floating rate senior notes we completed on June 16, 2006, and the use of proceeds therefrom, had occurred at the beginning of the period presented. Management believes the assumptions and allocations are reasonable. However, the pro forma results do not necessarily represent what the actual results would have been had Viacom been a stand alone public company, nor are they necessarily indicative of future results.

The pro forma adjustment to interest expense has been determined by adding (i) the annual interest charge of $302.7 million for the issuances of the fixed rate senior notes and senior debentures on April 12, 2006 as if such senior notes and senior debentures were outstanding as of January 1, 2005 and (ii) the annual interest

charge of $41.9 million for the issuance of $716 million of floating rate senior notes on June 16, 2006, based on an annual interest rate of 5.69%, being LIBOR plus 0.35%, which was utilized to repay the remaining $716 million of the $5.41 billion of debt incurred to pay the special dividend made to CBS Corporation in connection with the separation from the former Viacom Inc. under the terms of the Separation Agreement as if such floating rate senior notes were outstanding as of January 1, 2005.

(4)	Pro forma adjustment to the provision for income taxes calculated using blended statutory rates in effect for 2005.

(5)

Basic Earnings per Share (“EPS”) is computed by dividing net earnings by the number of shares of common stock issued and outstanding at the date of the separation as if such shares were outstanding for the full year. Diluted EPS is computed by dividing net earnings by the number of shares issued and outstanding at the date of separation adjusted to give effect to all potentially dilutive common shares weighted for the full year-ended December 31, 2005.

The pro forma adjustment to interest expense, net has been determined by adding (i) the interest charge of $87.4 million for the issuances of the fixed rate senior notes and senior debentures on April 12, 2006 as if such senior notes and senior debentures were outstanding as of January 1, 2006 until April 11, 2006 plus (ii) the interest charge of $19.8 million for the issuance of floating rate senior notes on June 16, 2006, based on an annual interest rate of 5.69%, being LIBOR plus 0.35%, as if such floating rate senior notes were outstanding as of January 1, 2006 until June 15, 2006 less (iii) the interest expense savings of $84.0 million (calculated based on actual interest rates in effect) for the nine months ended September 30, 2006 resulting

S-8

from utilizing the net proceeds from the issuances of the fixed rate senior notes and senior debentures on April 12, 2006 and the floating rate senior notes on June 16, 2006 to repay a portion of the term credit facility due in 2007 as if such amounts were repaid as of January 1, 2006. This adjustment does not give effect to the offering of the senior notes offered hereby and the use of the net proceeds therefrom. If this adjustment did give effect to those events as if they had occurred on January 1, 2006, then for each percentage point by which the annual interest rate on the senior notes offered hereby exceeds approximately 5.3%, this adjustment would increase by approximately $0.75 million per $100 million of senior notes offered hereby.

DESCRIPTION OF THE SENIOR NOTES

General

The senior notes due 2055 offered hereby (the “senior notes”) will be issued under an indenture dated as of April 12, 2006 (the “base indenture”), as supplemented by a first supplemental indenture dated April 12, 2006, as further supplemented by a second supplemental indenture dated as of June 16, 2006 and as further supplemented by a third supplemental indenture dated as of , 2006 between Viacom Inc., as issuer (in this Description of the Senior Notes, “Viacom”), and The Bank of New York, as trustee (the “Trustee”) (such supplements, together with the base indenture, the “indenture”) between Viacom and the Trustee. In this Description of the Senior Notes, “Viacom,” “we,” “us,” “our” and similar words refer to Viacom Inc. and not to any of its consolidated subsidiaries unless the context otherwise requires.

We provide information to you about the senior notes in two separate documents:

•

this prospectus supplement; and

•

the accompanying prospectus.

The following statements about the senior notes are summaries and are subject to, and qualified in their entirety by reference to, the accompanying prospectus and the indenture. See “Description of Debt Securities” in the accompanying prospectus for additional information concerning the securities and the indenture. The following statements, therefore, do not contain all of the information that may be important to you. Not all the defined terms used in this prospectus supplement are defined herein, and you should refer to the accompanying prospectus or the indenture for the definitions of such terms. The provisions of the indenture set forth the terms of the senior notes in greater detail than this prospectus supplement or the accompanying prospectus. If the statements in this prospectus supplement differ from the provisions of the indenture, the provisions of the indenture control. A copy of the base indenture was filed with the Securities and Exchange Commission as an exhibit to our current report on Form 8-K filed on April 17, 2006.

The senior notes:

•

will be unsecured senior obligations of Viacom;

•

will rank equally with all of our other unsecured senior indebtedness from time to time outstanding;

•

will initially be limited to $250,000,000 aggregate principal amount of senior notes, which aggregate principal amount may, without the consent of holders, be increased in the future on the same terms as to status, CUSIP number or otherwise as the senior notes being offered hereby; and

•

will be issued in minimum denominations of $25 and integral multiples thereof.

The senior notes are subject in all cases to any tax, fiscal or other law or regulation or administrative or judicial interpretation applicable thereto. We are not required to make any payment to a holder with respect to any tax, assessment or other governmental charge imposed (by withholding or otherwise) by any government or a political subdivision or taxing authority thereof or therein due and owing with respect to the senior notes.

Principal, Maturity and Interest

Each senior note will bear interest at a rate of % per year. Interest will be payable quarterly in arrears on the senior notes on , , and of each year, beginning on , 2007, each an interest payment date, and will be computed on the basis of a 360-day year of twelve 30-day months. Interest on the senior notes will accrue from and including the settlement date and will be paid to holders of record on the , , and immediately before the respective interest payment date.

The senior notes will mature on , 2055. On the maturity date of the senior notes, the holders will be entitled to receive 100% of the principal amount of the senior notes.

S-10

If any interest payment date falls on a day that is not a business day, then payment of interest may be made on the next succeeding business day and no interest will accrue because of such delayed payment.

Ranking

The senior notes will be unsecured senior obligations of Viacom Inc. and will rank equally with all of Viacom Inc.’s existing and future unsecured senior obligations. As of September 30, 2006, Viacom Inc. had approximately $7.84 billion of indebtedness outstanding under its credit facilities, its outstanding fixed rate senior notes and senior debentures issued on April 12, 2006, its outstanding floating rate senior notes issued on June 16, 2006 and its commercial paper program.

We conduct our operations through subsidiaries. As a result, distributions or advances from our subsidiaries are a major source of funds necessary to meet our debt service and other obligations. Contractual provisions, laws or regulations, as well as our subsidiaries’ financial condition and operating requirements, may limit our ability to obtain cash required to pay our debt service obligations, including payments on the senior notes. The senior notes will be structurally subordinated to all obligations of our subsidiaries including claims with respect to trade payables. This means that holders of the senior notes will have a junior position to the claims of creditors of our subsidiaries on the assets and earnings of such subsidiaries. As of September 30, 2006, our direct and indirect subsidiaries had approximately $343.3 million of indebtedness outstanding.

Further Issues

We may from time to time, without notice to or the consent of the holders of the senior notes currently offered hereby, create and issue further senior notes ranking equally and ratably in all respects with the senior notes, or in all respects except for the payment of interest accruing prior to the issue date or except, in some circumstances, for the first payment of interest following the issue date of those further senior notes. Any such further senior notes will be consolidated with and form a single series with the senior notes currently being offered and will have the same terms as to status, CUSIP number or otherwise as such senior notes. Any such further senior notes will be issued pursuant to a resolution of our board of directors, a supplement to the indenture or under an officer’s certificate pursuant to the indenture.

Optional Redemption

Prior to , 2011, we may not redeem the senior notes. We may redeem the senior notes, in whole or in part, at any time and from time to time on or after , 2011, upon not less than 30 nor more than 60 days’ notice, at a redemption price equal to 100% of the principal amount redeemed plus accrued and unpaid interest to the redemption date.

On and after the redemption date, interest will cease to accrue on the senior notes or any portion of the senior notes called for redemption (unless we default in the payment of the redemption price and accrued interest). On or before the redemption date, we will deposit with the Trustee money sufficient to pay the redemption price of and (unless the redemption date shall be an interest payment date) accrued and unpaid interest to the redemption date on the senior notes to be redeemed on such date. If less than all of the senior notes are to be redeemed, the senior notes to be redeemed shall be selected by the Trustee by such method as the Trustee shall deem fair and appropriate. Additionally, we may at any time repurchase senior notes in the open market and may hold or surrender such senior notes to the Trustee for cancellation.

No Mandatory Redemption or Sinking Fund

There will be no mandatory redemption prior to maturity or sinking fund payments for the senior notes.

The Trustee, Security Registrar and Paying Agent

The Bank of New York, acting through its principal corporate trust office at 101 Barclay Street, 8W, New York, New York, 10286 is the Trustee for the senior notes and is the security registrar and paying agent for the

S-11

senior notes. Principal and interest will be payable, and the senior notes will be transferable, at the office of the paying agent and security registrar. We may, however, pay interest by check mailed to registered holders of the senior notes. At the maturity of the senior notes, the principal, together with accrued interest thereon, will be payable in immediately available funds upon surrender of such senior notes at the office of the Trustee.

Events of Default

See “Description of Debt Securities—Defaults and Remedies” in the accompanying prospectus.

Application of Defeasance Provision

The accompanying prospectus contains a section entitled “Description of Debt Securities—Defeasance and Covenant Defeasance.” That section describes provisions for the full defeasance and covenant defeasance of securities issued under the indenture. Those provisions will apply to the senior notes.

To effect full defeasance or covenant defeasance of the senior notes, we would be required to deliver to the Trustee an opinion of counsel to the effect that the deposit of money or U.S. government obligations in the trust created when we elect full defeasance or covenant defeasance will not cause the holders of the affected series of securities to recognize income, gain or loss for federal income tax purposes.

Book Entry, Delivery and Form

The senior notes will be issued in the form of one or more fully registered global securities (each a “Global Security”) which will be deposited with, or on behalf of, The Depository Trust Company, New York, New York (the “Depositary”) and registered in the name of Cede & Co., the Depositary’s nominee. We will not issue senior notes in certificated form except in certain circumstances. Beneficial interests in the Global Securities will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in the Depositary (the “Depositary Participants”). Investors may elect to hold interests in the Global Securities through either the Depositary (in the United States), or Clearstream Banking Luxembourg (“Clearstream Luxembourg”) or Euroclear (in Europe) if they are participants in those systems, or, indirectly through organizations that are participants in those systems. Clearstream Luxembourg and Euroclear will hold interests on behalf of their participants through customers’ securities accounts in Clearstream Luxembourg’s and Euroclear’s names on the books of their respective depositaries, which in turn will hold such interests in customers’ securities accounts in the depositaries’ names on the books of the Depositary. At the present time, Citibank, N.A. acts as U.S. depositary for Clearstream Luxembourg and JPMorgan Chase Bank acts as U.S. depositary for Euroclear (the “U.S. Depositaries”). Beneficial interests in the Global Securities will be held in minimum denominations of $25 and integral multiples thereof. Except as set forth below, the Global Securities may be transferred, in whole but not in part, only to another nominee of the Depositary or to a successor of the Depositary or its nominee.

The Depositary has advised us and the underwriters that it is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. The Depositary holds securities that its participants (“Direct Participants”) deposit with the Depositary. The Depositary also facilitates the settlement among Direct Participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in Direct Participants’ accounts, thereby eliminating the need for physical movement of securities certificates. Direct Participants include securities brokers and dealers (which may include the underwriters of the senior notes), banks, trust companies, clearing corporations and certain other organizations. The Depositary is owned by a number of its Direct Participants and by the New York Stock Exchange, Inc., the American Stock Exchange LLC, and the National Association of Securities Dealers, Inc. Access to the Depositary’s book-entry system is also available to

S-12

others such as securities brokers and dealers, banks and trust companies that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly (“Indirect Participants”). The rules applicable to the Depositary and its Direct and Indirect Participants are on file with the Securities and Exchange Commission.

Clearstream Luxembourg has advised us that it is incorporated under the laws of Luxembourg as a professional depositary. Clearstream Luxembourg holds securities for its participating organizations, known as Clearstream Luxembourg participants, and facilitates the clearance and settlement of securities transactions between Clearstream Luxembourg participants through electronic book-entry changes in accounts of Clearstream Luxembourg participants, thereby eliminating the need for physical movement of certificates. Clearstream Luxembourg provides to Clearstream Luxembourg participants, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream Luxembourg interfaces with domestic markets in several countries. As a professional depositary, Clearstream Luxembourg is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector, also known as the Commission de Surveillance du Secteur Financier. Clearstream Luxembourg participants are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations and may include the underwriters of the senior notes or their affiliates. Indirect access to Clearstream Luxembourg is also available to others, such as banks, brokers, dealers and trust companies that clear through, or maintain a custodial relationship with, a Clearstream Luxembourg participant either directly or indirectly.

Distributions with respect to the senior notes held beneficially through Clearstream Luxembourg will be credited to the cash accounts of Clearstream Luxembourg participants in accordance with its rules and procedures, to the extent received by the U.S. Depositary for Clearstream Luxembourg.

Euroclear has advised us that it was created in 1968 to hold securities for its participants, known as Euroclear participants, and to clear and settle transactions between Euroclear participants and between Euroclear participants and participants of certain other securities intermediaries through simultaneous electronic book-entry delivery against payment, eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear is owned by Euroclear Clearance System Public Limited Company and operated through a license agreement by Euroclear Bank S.A./N.V., known as the Euroclear operator. The Euroclear operator provides Euroclear participants, among other things, with safekeeping, administration, clearance and settlement, securities lending and borrowing and related services. Euroclear participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries and may include the underwriters of the senior notes.

Indirect access to Euroclear is also available to others that clear through or maintain a custodial relationship with a Euroclear participant, either directly or indirectly.

The Euroclear operator is regulated and examined by the Belgian Banking and Finance Commission.

Securities clearance accounts and cash accounts with the Euroclear operator are governed by the Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System, and applicable Belgian law, collectively referred to as the terms and conditions. The terms and conditions govern transfers of securities and cash within Euroclear, withdrawals of securities and cash from Euroclear, and receipts of payments with respect to securities in Euroclear. All securities in Euroclear are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. The Euroclear operator acts under the terms and conditions only on behalf of Euroclear participants, and has no record of or relationship with persons holding through Euroclear participants.

Distributions with respect to senior notes held beneficially through Euroclear will be credited to the cash accounts of Euroclear participants in accordance with the terms and conditions, to the extent received by the U.S. Depositary for Euroclear.

S-13

If the Depositary is at any time unwilling or unable to continue as depositary and a successor depositary is not appointed by us within 90 days, we will issue the senior notes in definitive form in exchange for the entire Global Security representing such senior notes. In this case, an owner of a beneficial interest in the Global Security will be entitled to physical delivery in definitive form of senior notes represented by such Global Security equal in principal amount to such beneficial interest and to have such senior notes registered in its name.

Title to book-entry interests in the senior notes will pass by book-entry registration of the transfer within the records of Clearstream Luxembourg, Euroclear or the Depositary, as the case may be, in accordance with their respective procedures. Book-entry interests in the senior notes may be transferred within Clearstream Luxembourg and within Euroclear and between Clearstream Luxembourg and Euroclear in accordance with procedures established for these purposes by Clearstream Luxembourg and Euroclear. Book-entry interests in the senior notes may be transferred within the Depositary in accordance with procedures established for this purpose by the Depositary. Transfers of book-entry interests in the senior notes among Clearstream Luxembourg and Euroclear and the Depositary may be effected in accordance with procedures established for this purpose by Clearstream Luxembourg, Euroclear and the Depositary.

Global Clearance and Settlement Procedures

Initial settlement for the senior notes will be made in immediately available funds. Secondary market trading between Depositary Participants will occur in the ordinary way in accordance with the Depositary’s rules and will be settled in immediately available funds using the Depositary’s Same-Day Funds Settlement System. Secondary market trading between Clearstream Luxembourg participants and Euroclear participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream Luxembourg and Euroclear and will be settled using the procedures applicable to conventional eurobonds in immediately available funds.

Cross-market transfers between persons holding directly or indirectly through the Depositary on the one hand, and directly or indirectly through Clearstream Luxembourg participants or Euroclear participants, on the other, will be effected through the Depositary in accordance with the Depositary’s rules on behalf of the relevant European international clearing system by its U.S. Depositary; however, such cross-market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in such system in accordance with its rules and procedures and within its established deadlines (European time).

The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to its U.S. Depositary to take action to effect final settlement on its behalf by delivering or receiving the senior notes in the Depositary, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to the Depositary. Clearstream Luxembourg participants and Euroclear participants may not deliver instructions directly to their respective U.S. Depositaries.

Because of time-zone differences, credits of the senior notes received in Clearstream Luxembourg or Euroclear as a result of a transaction with a Depositary Participant will be made during subsequent securities settlement processing and dated the business day following the Depositary settlement date. Such credits, or any transactions in the senior notes settled during such processing, will be reported to the relevant Euroclear participants or Clearstream Luxembourg participants on that business day. Cash received in Clearstream Luxembourg or Euroclear as a result of sales of senior notes by or through a Clearstream Luxembourg participant or a Euroclear participant to a Depositary Participant will be received with value on the business day of settlement in the Depositary but will be available in the relevant Clearstream Luxembourg or Euroclear cash account only as of the business day following settlement in the Depositary.

Although the Depositary, Clearstream Luxembourg and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of securities among participants of the Depositary, Clearstream Luxembourg and Euroclear, they are under no obligation to perform or continue to perform such procedures and they may discontinue the procedures at any time.

EUROPEAN UNION DIRECTIVE ON THE TAXATION OF SAVINGS INCOME

The European Union has adopted a Directive regarding the taxation of savings income. The Directive provides for member states of the European Union (each, a “Member State,” and together, “Member States”) to provide to the tax authorities of other Member States details of payments of interest and other similar income paid by a person to an individual in another Member State, except that Austria, Belgium and Luxembourg will instead impose a withholding system for a transitional period unless during such period they elect otherwise.

UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following discussion is a summary of certain United States federal income tax consequences of the purchase, ownership and disposition of the senior notes to the holders of senior notes that purchase the senior notes at original issuance at their initial issue price, and that hold the senior notes as capital assets (generally, property held for investment). This summary is based on the Internal Revenue Code of 1986, as amended (the “Code”), administrative pronouncements, judicial decisions and existing and proposed Treasury Regulations, and interpretations of the foregoing, changes to any of which subsequent to the date of this prospectus supplement may affect the tax consequences described herein. This summary does not address all of the tax consequences that may be relevant to holders in light of their particular circumstances or to holders subject to special tax rules, such as certain financial institutions, insurance companies, tax-exempt organizations, partnerships and other pass-through entities, dealers in securities or foreign currencies, United States Holders (as defined below) whose functional currency (as defined in Section 985 of the Code) is not the U.S. dollar, persons holding senior notes in connection with a hedging transaction, “straddle,” conversion transaction or other integrated transaction, traders in securities that elect to mark to market, holders liable for alternative minimum tax or persons who have ceased to be United States citizens or to be taxed as resident aliens. Persons considering the purchase of the senior notes should consult their tax advisors concerning the application of United States federal income tax laws, as well as the laws of any state, local or foreign taxing jurisdictions and any other tax laws, including gift and estate tax liability, as may be applicable to their particular situations.

Viacom believes that the senior notes constitute indebtedness for United States federal income tax purposes, and the following discussion assumes such treatment. No ruling has been or will be obtained from the Internal Revenue Service (“IRS”) regarding the United States federal income tax treatment of the senior notes, and no assurances can be given that the IRS will not take a contrary position.

As used in this section, a “United States Holder” means a beneficial owner of senior notes that is, for United States federal income tax purposes, a United States person. For this purpose, a “United States person” means (i) any individual who is a citizen or resident of the United States, (ii) a corporation, or other entity taxable as a corporation created or organized in or under the laws of the United States, any State thereof or the District of Columbia, (iii) any estate the income of which is subject to United States federal income taxation regardless of its source, or (iv) any trust if a court within the United States is able to exercise primary supervision over the administration of the trust and one or more United States persons have the authority to control all substantial decisions of the trust. Notwithstanding the preceding sentence, certain trusts in existence on August 20, 1996 and treated as United States persons prior to such date may elect to continue to be treated as United States persons.

A “United States Alien Holder” is a beneficial owner of senior notes that is neither a United States person nor a partnership or other entity treated as a partnership for United States federal income tax purposes. If a holder of the senior notes is a partnership or other entity treated as a partnership for United States federal income tax purposes, the tax treatment of the partnership and each partner in such partnership generally will depend on the activities of the partnership and the status of the partner. Partnerships that hold notes, and partners in such partnerships, should consult their own tax advisors.

S-15

Tax Consequences to United States Holders

Payments of Stated Interest

Stated interest on senior notes will generally be taxable to a United States Holder as ordinary interest income at the time any such interest accrues or is received in accordance with the United States Holder’s regular method of accounting for United States federal income tax purposes.

Sale, Taxable Exchange, Redemption, Retirement or other Taxable Disposition of the Senior Notes

A United States Holder will recognize gain or loss on the sale, taxable exchange, redemption, retirement or other taxable disposition of a senior note in an amount equal to the difference between the amount realized upon the disposition (less any portion allocable to any accrued and unpaid interest, which will be taxable as ordinary income to the extent not previously included in gross income) and the United States Holder’s adjusted tax basis in the senior note. Such gain or loss generally will be a capital gain or loss, and will be a long-term capital gain or loss if the United States Holder has held the senior note for more than one year. A United States Holder’s adjusted tax basis in a senior note generally will be the cost of the senior note, less any principal payments received by such United States Holder. Under current law, long-term capital gains of certain United States Holders (including individuals) generally are eligible for reduced rates of United States federal income tax. The deductibility of capital losses is subject to limitations under the Code.

Tax Consequences to United States Alien Holders

Under present United States federal income tax law, and subject to the discussion below concerning backup withholding:

(a)

payments of interest on the senior notes by Viacom or its paying agent to any United States Alien Holder will be exempt from the 30% United States federal withholding tax, provided that (i) such holder does not own, actually or constructively, directly or indirectly, 10% or more of the total combined voting power of all classes of stock of Viacom entitled to vote, (ii) such holder is not a controlled foreign corporation related, directly or indirectly, to Viacom through stock ownership, (iii) such holder is not a bank that received such senior notes in an extension of credit made pursuant to a loan agreement entered into in the ordinary course of its trade or business, (iv) the requirement to certify such holder’s non-U.S. status, as set forth in Section 871(h) or Section 881(c) of the Code and under applicable Treasury Regulations has been fulfilled with respect to the beneficial owner, as discussed below and (v) the interest is not effectively connected with the conduct by such holder of a trade or business in the United States; and

(b)

a United States Alien Holder of senior notes will not be subject to United States federal income tax on gain realized on the sale, taxable exchange, redemption, retirement or other taxable disposition of such senior notes, unless (i) such holder is an individual who is present in the United States for 183 days or more in the taxable year of the disposition, and either the gain is attributable to an office or other fixed place of business maintained by such individual in the United States or, generally, such individual has a “tax home” in the United States or (ii) such gain is effectively connected with the holder’s conduct of a trade or business in the United States (and, if an income tax treaty applies, generally is attributable to a U.S. “permanent establishment” maintained by such holder).

The certification requirement referred to in subparagraph (a) will be fulfilled if the United States Alien Holder of senior notes certifies on IRS Form W-8BEN or successor form under penalties of perjury, that such owner is not a United States person and provides its name and address, and (i) such United States Alien Holder files such Form W-8BEN or successor form with the withholding agent or (ii) in the case of senior notes held on behalf of the beneficial owner by a securities clearing organization, bank or other financial institution holding customers’ securities in the ordinary course of its trade or business, such financial institution files with the withholding agent a statement that it has received the Form W-8BEN or successor form from the United States Alien Holder of the senior notes, furnishes the withholding agent with a copy thereof, and otherwise complies with the applicable IRS requirements.

S-16

If a United States Alien Holder of senior notes is engaged in a trade or business in the United States, and if interest on the senior notes (or gain realized on their sale, taxable exchange or other disposition) is effectively connected with the conduct of such trade or business (and, if an income tax treaty applies, generally is attributable to a U.S. “permanent establishment” maintained by such holder), the United States Alien Holder, although exempt from the withholding tax discussed in the preceding paragraphs, will be subject to regular United States federal income tax on such effectively connected interest (or gain), generally in the same manner as if it were a United States Holder. See “Tax Consequences to United States Holders” above. In lieu of the certificate described in the preceding paragraph, such a United States Alien Holder will be required to provide to the withholding agent a properly executed IRS Form W-8ECI or successor form, as appropriate, to claim an exemption from withholding tax. In addition, if such United States Alien Holder is a foreign corporation, it may be subject to a 30% branch profits tax (unless reduced or eliminated by an applicable treaty) on its earnings and profits for the taxable year attributable to such effectively connected interest (or gain), subject to certain adjustments.

Backup Withholding and Information Reporting

Under current United States federal income tax law, information reporting requirements apply to certain payments of principal, interest, or proceeds of sales or other dispositions to noncorporate United States Holders. In addition, a backup withholding tax will apply to such payments (currently at a rate of 28%) if the noncorporate United States Holder (i) fails to furnish its Taxpayer Identification Number (“TIN”) which, for an individual, is his or her Social Security Number, (ii) furnishes an incorrect TIN, (iii) is notified by the IRS that it is subject to backup withholding for failure to report interest and dividend payments, or (iv) under certain circumstances fails to certify, under penalties of perjury, that it has furnished a correct TIN and has not been notified by the IRS that it is subject to backup withholding for failure to report interest and dividend payments. United States Holders should consult their tax advisors regarding their qualification for exemption from backup withholding and the procedure for obtaining such an exemption if applicable. Backup withholding is not additional tax. Any amount withheld under the backup withholding rules generally will be allowed as a refund or credit against a United States Holder’s United States federal income tax liability, provided that the required information is timely furnished to the IRS.

Interest payments made to a United States Alien Holder will generally be reported to such holder and to the IRS on Form 1042-S or any successor form. Copies of the information returns reporting such interest payments and any withholding may also be made available to the tax authorities in the country in which a United States Alien Holder resides under the provisions of an applicable tax treaty.

Backup withholding will not apply to payments made on the senior notes if the certifications required by Sections 871(h) and 881(c) of the Code as described above are properly submitted, provided that Viacom or its paying agent or the qualified intermediary, as the case may be, does not have actual knowledge or reason to know that the payee is a United States person. Under current Treasury Regulations, payments on the sale, taxable exchange, redemption, retirement, or other taxable disposition of notes made to or through a foreign office of a broker generally will not be subject to backup withholding. However, if such broker is:

•

a United States person;

•

a controlled foreign corporation for United States federal income tax purposes;

•

a foreign person 50% or more of whose gross income for certain periods is effectively connected with a United States trade or business; or

•

a foreign partnership with certain connections to the United States;

then information reporting will be required unless the broker has in its records documentary evidence that the beneficial owner is not a United States person and certain other conditions are met or the beneficial owner

S-17

otherwise establishes an exemption. Backup withholding may apply to any payment that such broker is required to report if the broker has actual knowledge or reason to know that the payee is a United States person. Payments to or through the United States office of a broker will be subject to backup withholding and information reporting unless the United States Alien Holder certifies, under penalties of perjury, that it is not a United States person and the payor does not have actual knowledge or reason to know that the United States Alien Holder is a United States person, or the United States Alien Holder otherwise establishes an exemption.

United States Alien Holders of the senior notes should consult their tax advisors regarding the application of information reporting and backup withholding in their particular situations, the availability of an exemption therefrom, and the procedure for obtaining such an exemption, if available. Any amounts withheld from a payment to a United States Alien Holder under the backup withholding rules will be allowed as a credit against such United States Alien Holder’s United States federal income tax liability and may entitle such United States Alien Holder to a refund, provided that the United States Alien Holder files a United States income tax return and the required information is timely furnished to the IRS.

S-18

The underwriters are offering the senior notes, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the senior notes, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officer’s certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

Over-Allotment Option

We have granted to the underwriters an option, exercisable for 30 days from the date of this prospectus supplement, to purchase up to an additional $ aggregate principal amount of senior notes at the public offering price less the underwriting discount. The underwriters may exercise the option solely for the purpose of covering over-allotments, if any, in connection with this offering. To the extent the option is exercised, each underwriter must purchase a number of additional senior notes approximately proportionate to that underwriter’s initial purchase commitment. If the underwriters exercise their over-allotment option in full the total price to the public would be $ , the total underwriting discounts and commissions would be $ and the total proceeds, before deducting expenses, to us would be $ .

Commissions and Discounts

The underwriters have advised us that they propose initially to offer the senior notes to the public at the public offering price on the cover page of this prospectus supplement, and to dealers at that price less a concession not in excess of $ per senior note for retail orders and $ per senior note for institutional orders. The underwriters may allow, and the dealers may reallow, a discount not in excess of $ per senior note to other dealers. After the initial public offering, the public offering prices, concessions and discounts may be changed.

The expenses of the offering, not including the underwriting discount, are estimated to be $ and are payable by us.

S-19

The following table shows the underwriting discounts and commissions that we are to pay to the underwriters in connection with this offering. These amounts are shown assuming both no exercise and full exercise of the underwriters’ option to purchase additional senior notes.


	No Exercise	Full Exercise
Per senior note (retail orders)	$	$
Per senior note (institutional orders)	$	$
Total	$	$

New Issue of Senior Notes

The senior notes are a new issue of securities with no established trading market. Application has been made to list the senior notes on the New York Stock Exchange. We expect trading in the senior notes on the New York Stock Exchange to begin within 30 days after the original issue date.

We have been advised by the underwriters that they presently intend to make a market in the senior notes after completion of the offering. However, they are under no obligation to do so and may discontinue any market-making activities at any time without any notice. We cannot assure the liquidity of the trading market for the senior notes or that an active public market for the senior notes will develop. If an active public trading market for the senior notes does not develop, the market price and liquidity of the senior notes may be adversely affected.

Price Stabilization and Short Positions

In connection with the offering, the underwriters are permitted to engage in transactions that stabilize the market price of the senior notes. These stabilization transactions consist of bids or purchases to peg, fix or maintain the price of the senior notes. Specifically, the underwriters may sell a principal amount of senior notes greater than they are obligated to purchase under the underwriting agreement, creating a short position. A short sale is covered if the short position is no greater than the principal amount of senior notes available for purchase by the underwriters under the over-allotment option. The underwriters can close out a covered short sale by exercising the over-allotment option or purchasing senior notes in the open market. In determining the source of senior notes to close out a covered short sale, the underwriters will consider, among other things, the open market price of shares compared to the price available under the over-allotment option. The underwriters may also sell a principal amount of senior notes in excess of the over-allotment option, creating a naked short position. The underwriters must close out any naked short position by purchasing senior notes in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the senior notes in the open market after pricing that could adversely affect investors who purchase in this offering. As an additional means of facilitating this offering, the underwriters may bid for, and purchase, senior notes in the open market to stabilize the price of the senior notes. Purchases of a security to stabilize the price or to reduce a short position could cause the price of the security to be higher than it might be in the absence of such purchases.

Neither we nor any of the underwriters makes any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the senior notes. In addition, neither we nor any of the underwriters makes any representation that the underwriters will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

Other Relationships

The underwriters and their affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us. They have received customary fees and commissions for these transactions.

Engaging our audiences through television, motion pictures and digital platforms, we seek to reach our audiences wherever they consume content. Our leading brands include the multiplatform properties of MTV Networks: MTV: Music Television^®, VH1^®, Nickelodeon^®, Nick at Nite^®, Comedy Central^®, CMT^®: Country Music Television^™, Spike TV^®, TV Land^®, Logo^™ and more than 130 networks around the world, as well as digital assets such as Neopets^®, Xfire^® and Atom Entertainment^™; BET^®; Paramount Pictures^®, Paramount Vantage^™, Paramount Home Entertainment, DreamWorks^® and Famous Music^®.

USE OF PROCEEDS

Unless indicated otherwise in a prospectus supplement, we expect to use the proceeds, net of transaction costs, from the sale of our securities for general corporate purposes, including, but not limited to, acquisitions, repayment of borrowings, working capital, capital expenditures and stock repurchases.

RATIO OF EARNINGS TO FIXED CHARGES

Set forth below is information concerning our ratio of earnings to fixed charges. For purposes of determining the ratio of earnings to fixed charges, earnings consist of earnings from continuing operations before income taxes plus distributed income of equity affiliates and fixed charges. Fixed charges are defined as interest expense and one-third of gross rent expense relating to operating leases which is deemed to be representative of interest. For the nine months ended September 30, 2006, fixed charges include interest expense on indebtedness outstanding during that period. For periods ending December 31, 2005 and prior, indebtedness, other than certain capital lease obligations, was not transferred to Viacom as it remained at CBS Corporation. Accordingly, debt service cost is not reflected in periods prior to the nine months ended September 30, 2006.

Interest expense increased for the first nine months of 2006 primarily due to higher average debt outstanding and higher interest rates. The higher debt outstanding resulted principally from funding the special dividend payment made to CBS Corporation in connection with the separation from Former Viacom in December 2005, the purchase of DreamWorks L.L.C. on January 31, 2006, and the purchase of common stock under the Company’s stock repurchase program which commenced in January 2006. Interest expense will increase substantially for the remainder of 2006 versus 2005 as this higher level of debt is expected to be outstanding for the entire year.

DESCRIPTION OF DEBT SECURITIES

The following description of Viacom’s debt securities to be issued under the Indenture (as defined below) summarizes the general terms and provisions of its debt securities to which any prospectus supplement may relate. The description set forth below and in any prospectus supplement is not complete and is subject to, and qualified in its entirety by reference to, the Indenture. Viacom will describe the specific terms of the debt securities offered by any prospectus supplement and the extent, if any, to which the general provisions summarized in this description may apply to any series of its debt securities in the prospectus supplement relating to that series. References to “Viacom” in this description are references to Viacom Inc. and not its consolidated subsidiaries, unless the context otherwise requires.

Viacom may issue its debt securities from time to time, in one or more series under an indenture dated as of April 12, 2006, as supplemented by a first supplemental indenture dated as of April 12, 2006 and as further supplemented by a second supplemental indenture dated as of June 16, 2006, between Viacom and The Bank of New York, as trustee, or another trustee named in a prospectus supplement. We refer to this indenture, as so supplemented, as the “Indenture.” The trustee under the Indenture is called the “Trustee.”

The Indenture does not limit the amount of debt securities that may be issued thereunder. The Indenture provides that debt securities may be issued up to an aggregate principal amount authorized by Viacom and may be payable in any currency or currency unit designated by Viacom.

General

Viacom may issue debt securities from time to time and offer its debt securities on terms determined by market conditions at the time of their sale. Viacom may issue debt securities in one or more series with the same or various maturities and at the same or various prices including at par, at a premium, or at a discount. Any debt securities bearing no interest or interest at a rate which at the time of issuance is below market rates will be sold at a discount, which may be substantial, from the stated principal amount. Viacom will describe the material United States federal income tax consequences and other special considerations applicable to any substantially discounted debt securities in a related prospectus supplement.

You should refer to the prospectus supplement for the following terms of the debt securities offered by this registration statement:

•

the designation, aggregate principal amount and authorized denominations of the debt securities;

•

the percentage of the principal amount at which Viacom will issue the debt securities;

•

the date(s) on which the debt securities will mature;

•

the annual interest rate(s) of the debt securities, or the method of determining the rate(s);

•

the date(s) on which any interest will be payable, the date(s) on which payment of any interest will commence and the regular record date(s) for the payment of interest;

•

the terms of any mandatory or optional redemption(s), including any provisions for sinking, purchase or other similar funds or repayment options;

•

the currency unit(s) for which the debt securities may be purchased and in which the principal, any premium and any interest may be payable;

•

if the currency unit(s) for which the debt securities may be purchased or in which the principal, any premium and any interest may be payable is at Viacom’s election or the purchaser’s election, the manner in which the election may be made;

•

if the amount of payments on the debt securities is determined by an index based on one or more currency units, or changes in the price of one or more securities or commodities, the manner in which the amounts will be determined;

•

the extent to which any of the debt securities will be issuable in temporary or permanent global form, and the manner in which any interest payable on a temporary or permanent global security will be paid;

•

the terms and conditions upon which the debt securities may be convertible into or exchanged for common stock, preferred stock, indebtedness or other debt or equity securities of any person, including Viacom;

•

information with respect to book-entry procedures, if any;

•

a discussion of any material United States federal income tax and other special considerations, procedures and limitations relating to the debt securities; and

•

any other specific terms of the debt securities not inconsistent with the Indenture.

If Viacom sells any of the debt securities for one or more foreign currencies or foreign currency units or if the principal of, premium, if any, or interest on any series of debt securities will be payable in one or more foreign currencies or foreign currency units, it will describe the restrictions, elections, any material United States federal income tax consequences, specific terms and other information with respect to the issue of debt securities and the currencies or currency units in the related prospectus supplement.

Unless specified otherwise in a prospectus supplement, the principal of, premium, if any, and interest on the debt securities will be payable, and the debt securities will be transferable, at the corporate trust office of the applicable Trustee in New York, New York. However, Viacom may make payment of interest, at its option, by check mailed on or before the payment date to the address of the person entitled to the interest payment or by transfer to an account held by the payee as it appears on the registry books of the Trustee, Viacom or its agents.

Unless specified otherwise in a prospectus supplement, Viacom will issue the debt securities in registered form and in denominations of $1,000 and any integral multiple of $1,000. Bearer securities, other than those issued in global form, will be issued in denominations of $5,000. No service charge will be made for any transfer or exchange of any debt securities, but Viacom may, except in specific cases not involving any transfer, require payment of a sufficient amount to cover any tax or other governmental charge payable in connection with the transfer or exchange.

Viacom’s rights and the rights of its creditors, including holders of debt securities, to participate in any distribution of assets of any Viacom subsidiary upon its liquidation, reorganization or otherwise is subject to the prior claims of creditors of the subsidiary, except to the extent that Viacom’s claims as a creditor of the subsidiary may be recognized.

Ranking

Any senior debt securities will be senior unsecured obligations of Viacom and will rank equally in right of payment with all of Viacom’s other unsecured and unsubordinated indebtedness from time to time outstanding.

Any senior subordinated debt securities will be senior unsecured subordinated obligations of Viacom and will be subordinated in right of payment to Viacom’s senior indebtedness.

Any debt securities will be effectively subordinated to any secured indebtedness of Viacom to the extent of the value of the assets securing such indebtedness. The Indenture does not limit the amount of debt that Viacom or its subsidiaries can incur.

In addition, Viacom conducts its operations through subsidiaries, which generate a substantial portion of our operating income and cash flow. As a result, distributions or advances from our subsidiaries are a major source of funds necessary to meet our debt service and other obligations. Contractual provisions, laws or regulations, as well as a subsidiary’s financial condition and operating requirements, may limit the ability of Viacom to obtain cash required to pay Viacom’s debt service obligations, including payments on the debt securities. The debt

securities (whether senior or subordinated obligations of Viacom) will be structurally subordinated to all obligations of Viacom’s subsidiaries including claims with respect to trade payables. This means that holders of the debt securities of Viacom will have a junior position to the claims of creditors of Viacom’s subsidiaries on the assets and earnings of such subsidiaries. As of September 30, 2006, Viacom’s direct and indirect subsidiaries had approximately $343.3 million of indebtedness outstanding.

Global Securities

Viacom may issue debt securities of a series, in whole or in part, in the form of one or more global securities and will deposit them with, or on behalf of, a depositary identified in the prospectus supplement relating to that series. Viacom may issue global securities in fully registered or bearer form and in either temporary or permanent form. Unless and until it is exchanged in whole or in part for the individual debt securities represented thereby, a global security may only be transferred among the depositary, its nominees and any successors.

The specific terms of the depositary arrangement relating to a series of debt securities will be described in the prospectus supplement relating to that series. It is anticipated that the following provisions will generally apply to depositary arrangements.

Upon the issuance of a global security, the depositary for the global security or its nominee will credit on its book-entry registration and transfer system the principal amounts of the individual debt securities represented by the global security to the accounts of persons that have accounts with the depositary. The accounts will be designated by the dealers, underwriters or agents with respect to the debt securities, or by Viacom if the debt securities are offered and sold directly by it. Ownership of beneficial interests in a global security will be limited to persons that have accounts with the applicable depositary participants or persons that hold interests through these participants. Ownership of beneficial interests in a global security will be shown on, and the transfer of that ownership will be effected only through, records maintained by:

•

the applicable depositary or its nominee, with respect to interests of depositary participants; and

•

the records of depositary participants, with respect to interests of persons other than depositary participants.

So long as the depositary for a global security or its nominee is the registered owner of that global security, the depositary or the nominee will be considered the sole owner or holder of the debt securities represented by the global security for all purposes under the applicable debt indenture. Except as provided below, owners of beneficial interests in a global security will:

•

not be entitled to have any of the individual debt securities of the series represented by the global security registered in their names;

•

not receive, or be entitled to receive, physical delivery of any debt security of that series in definitive form; and

•

not be considered the owners or holders thereof under the Indenture governing the debt securities.

Further Issues

Not all debt securities of any one series need be issued at the same time and, unless otherwise provided, a series may be reopened without the consent of the holders for issuances of additional debt securities of such series.

Payment and Paying Agents

Any payments of principal, premium or interest on individual debt securities represented by a global security registered in the name of a depositary or its nominee will be made to the depositary or its nominee as the registered owner of the global security representing the debt securities. Neither Viacom, the Trustee, any paying

agent, nor the security registrar for the debt securities will have any responsibility or liability for the records relating to or payments made on account of beneficial ownership interests of the global security for the debt securities or for maintaining, supervising or reviewing any records relating to the beneficial ownership interests.

Viacom expects that the depositary for a series of debt securities or its nominee, upon receipt of any payment of principal, premium or interest in respect of a permanent global security representing any of the debt securities, will immediately credit participants’ accounts with payments in amounts proportionate to their beneficial interests in the principal amount of the global security for the debt securities as shown on the records of the depositary or its nominee. Viacom also expects that payments by participants to owners of beneficial interests in the global security held through the participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in “street name.” The payments will be the responsibility of those participants.

Merger, Consolidation or Sale of Assets

Under the terms of the Indenture, Viacom generally would be permitted to consolidate or merge with another entity or to sell all or substantially all of our respective assets to another entity, subject to Viacom meeting all of the following conditions:

•

the resulting entity (other than Viacom) must agree through a supplemental indenture to be legally responsible for the debt securities;

•

immediately following the consolidation, merger, sale or conveyance, no Event of Default (as defined below) shall have occurred and be continuing;

•

the surviving entity to the transaction must be a corporation organized under the laws of the United States or a state of the United States;

•

Viacom must deliver certain certificates and documents to the Trustee; and

•

Viacom must satisfy any other requirements specified in the prospectus supplement relating to a particular series of debt securities.

We may merge or consolidate with, or sell all or substantially all of our assets to any of our Subsidiaries.

Although there is a limited body of case law interpreting the phrase “all or substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, in certain circumstances there may be a degree of uncertainty as to whether a particular transaction would involve a disposition of “all or substantially all” of our assets. As a result, it may be unclear as to whether the merger, consolidation or sale of assets covenant would apply to a particular transaction as described above absent a decision by a court of competent jurisdiction.

In the event that Viacom consolidates or merges with another entity or sells all or substantially all of its assets to another entity, the surviving entity shall be substituted for Viacom under the Indenture and Viacom shall be discharged from all of its obligations under the Indenture.

Limitations on Liens

We covenant in the Indenture that we will not create, assume or permit any Lien on any of our properties or assets, unless we secure the debt securities at least equally and ratably to the secured Indebtedness. The foregoing only applies to Liens that in the aggregate exceed 15% of our total consolidated assets, reduced by the Attributable Debt related to any permitted sale and leaseback arrangement. See “—Limitations on Sale and Leaseback Transactions” below. The restrictions do not apply to Capitalized Leases or Indebtedness that is secured by:

•

Liens existing on the date such debt securities are issued;

•

Liens on any property or any Indebtedness of a person existing at the time the person becomes a Subsidiary (whether by acquisition, merger or consolidation);

•

Liens in favor of us or our Subsidiaries; and

•

Liens existing at the time of acquisition of the assets secured thereby and purchase money Liens.

The restrictions do not apply to extensions, renewals or replacements of any of the foregoing types of Liens.

Limitations on Sale and Leaseback Transactions

We covenant in the Indenture that neither we nor any Restricted Subsidiary will enter into any arrangement with any person to lease a Principal Property (except for any arrangements that exist on the date the debt securities are issued or that exist at the time any person that owns a Principal Property becomes a Restricted Subsidiary) that has been or is to be sold by us or the Restricted Subsidiary to the person unless:

•

the sale and leaseback arrangement involves a lease for a term of not more than three years;

•

the sale and leaseback arrangement is entered into between us and any Subsidiary or between our Subsidiaries;

•

we or the Restricted Subsidiary would be entitled to incur indebtedness secured by a Lien on the Principal Property at least equal in amount to the Attributable Debt permitted pursuant to the first paragraph under “—Limitations on Liens” without having to secure equally and ratably the debt securities;

•

the proceeds of the sale and leaseback arrangement are at least equal to the fair market value (as determined by our Board of Directors in good faith) of the property and we apply within 180 days after the sale an amount equal to the greater of the net proceeds of the sale or the Attributable Debt associated with the property to (i) the retirement of long-term debt for borrowed money that is not subordinated to the debt securities and that is not debt to us or a Subsidiary, or (ii) the purchase or development of other comparable property; or

•

the sale and leaseback arrangement is entered into within 180 days after the initial acquisition of the Principal Property subject to the sale and leaseback arrangement.

The term “Attributable Debt,” with regard to a sale and leaseback arrangement of a Principal Property, is defined in the Indenture as an amount equal to the lesser of: (a) the fair market value of the property (as determined in good faith by our Board of Directors); or (b) the present value of the total net amount of rent payments to be made under the lease during its remaining term, discounted at the rate of interest set forth or implicit in the terms of the lease, compounded semi-annually. The calculation of the present value of the total net amount of rent payments is subject to adjustments specified in the Indenture.

The term “Principal Property” is defined in the Indenture to include any parcel of our or our Restricted Subsidiaries’ real property and related fixtures or improvements located in the United States, the aggregate book value of which on the date of determination exceeds $1.5 billion. The term “Principal Property” does not include any telecommunications equipment or parcels of real property and related fixtures or improvements that are determined in good faith by our Board of Directors not to be of material importance to our and our Subsidiaries’ total business. As of the date of this prospectus, neither we nor any of our Subsidiaries own any Principal Property.

Defaults and Remedies

Holders of debt securities will have specified rights if an Event of Default (as defined below) occurs in respect of the debt securities of that series, as described below.

The term “Event of Default” in respect of the debt securities of a particular series means any of the following:

•

Viacom does not pay interest on a debt security of such series within 30 days of its due date;

•

Viacom does not pay the principal of or any premium on a debt security of such series when due and payable, at its maturity, or upon its acceleration or redemption;

•

Viacom remains in breach of a covenant or warranty in respect of the Indenture for 60 days after Viacom receives a written notice of default; such notice must be sent by either the Trustee or holders of at least 25% in principal amount of a series of outstanding debt securities; or

•

Viacom files for bankruptcy, or other events of bankruptcy specified in the Indenture, occur.

If an Event of Default has occurred, the Trustee or the holders of at least 25% in principal amount of the debt securities of the affected series may declare the entire unpaid principal amount (and premium, if any) of, and all the accrued interest on, the debt securities of that series to be due and immediately payable. This is called a declaration of acceleration of maturity. There is no action on the part of the Trustee or any holder of debt securities required for such declaration if the Event of Default is a bankruptcy, insolvency or reorganization. Holders of a majority in principal amount of the debt securities of a series may also waive certain past defaults under the Indenture on behalf of all of the holders of such series of debt securities. A declaration of acceleration of maturity may be canceled, under specified circumstances, by the holders of at least a majority in principal amount of a series of debt securities and the Trustee.

Except in cases of default, where the Trustee has special duties, the Trustee is not required to take any action under the Indenture at the request of holders unless the holders offer the Trustee reasonable protection from expenses and liability satisfactory to the Trustee. If a reasonable indemnity is provided, the holders of a majority in principal amount of a series of debt securities may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the Trustee. The Trustee may refuse to follow those directions in certain circumstances specified in the Indenture. No delay or omission in exercising any right or remedy will be treated as a waiver of the right, remedy or Event of Default.

Before holders are allowed to bypass the Trustee and bring a lawsuit or other formal legal action or take other steps to enforce their rights or protect their interests relating to the debt securities, the following must occur:

•

holders must give the Trustee written notice that an Event of Default has occurred and remains uncured;

•

holders of at least 25% in principal amount of the outstanding debt securities of a series must make a written request that the Trustee take action because of the default and must offer the Trustee indemnity satisfactory to the Trustee against the cost and other liabilities of taking that action;

•

the Trustee must have failed to take action for 60 days after receipt of the notice and offer of indemnity; and

•

holders of a majority in principal amount of the debt securities of a series must not have given the Trustee a direction inconsistent with the above notice for a period of 60 days after the Trustee has received the notice.

Holders are, however, entitled at any time to bring a lawsuit for the payment of money due on the debt securities on or after the due date.

Modification of the Indenture

The Indenture provides that Viacom and the Trustee may, without the consent of any holders of debt securities, enter into supplemental indentures for the purposes, among other things, of:

•

adding to Viacom’s covenants;

•

adding additional events of default;

•

changing or eliminating any provisions of the Indenture so long as there are no holders entitled to the benefit of the provisions;

•

establishing the form or terms of any series of debt securities; or

•

curing ambiguities or inconsistencies in the Indenture or making any other provisions with respect to matters or questions arising under the Indenture.

With specific exceptions, the Indenture or the rights of the holders of the debt securities may be modified by Viacom and the Trustee with the consent of the holders of a majority in aggregate principal amount of the debt securities of each series affected by the modification then outstanding; however, no modification may be made without the consent of the holders of each outstanding debt security affected, which would:

•

change the maturity of any payment of principal of, or any premium on, or any installment of interest on any debt security;

•

change the terms of any sinking fund with respect to any debt security;

•

reduce the principal amount of any debt security, or the interest thereon, or any premium on any debt security upon redemption or repayment at the option of the holder;

•

change any obligation of Viacom to pay additional amounts;

•

change any place of payment where, or the currency in which, any debt security or any premium or interest is payable;

•

impair the right to sue for the enforcement of any payment on or with respect to any debt security; or

•

reduce the percentage in principal amount of outstanding debt securities of any series required to consent to any supplemental indenture, any waiver of compliance with provisions of the Indenture or specific defaults and their consequences provided for in the Indenture, or otherwise modify the sections in the Indenture relating to these consents.

Defeasance and Covenant Defeasance

Viacom may elect either (i) to defease and be discharged from any and all obligations with respect to a series of the debt securities (except as otherwise provided in the Indenture) (“defeasance”) or (ii) to be released from its obligations with respect to certain covenants that are described in the Indenture (“covenant defeasance”), upon the deposit with the Trustee, in trust for such purpose, of money and/or government obligations that through the payment of principal and interest in accordance with their terms will provide money in an amount sufficient, without reinvestment, to pay the principal of, premium, if any, and interest on the debt securities of such series to maturity or redemption, as the case may be, and any mandatory sinking fund or analogous senior payments thereon. As a condition to defeasance or covenant defeasance, Viacom must deliver to the Trustee an opinion of counsel to the effect that the holders of the debt securities of such series will not recognize income, gain or loss for United States federal income tax purposes as a result of such defeasance or covenant defeasance and will be subject to United States federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance or covenant defeasance had not occurred. Such opinion of counsel, in the case of defeasance under clause (i) above, must refer to and be based upon a ruling of the Internal Revenue Service or a change in applicable United States federal income tax law occurring after the date of the Indenture.

Viacom may exercise its defeasance option with respect to the debt securities of any series notwithstanding its prior exercise of its covenant defeasance option. If Viacom exercises its defeasance option, payment of the debt securities of such series may not be accelerated because of an event of default. If Viacom exercises its covenant defeasance option, payment of the debt securities of such series may not be accelerated by reference to any covenant from which Viacom is released as described under clause (ii) of the immediately preceding paragraph. However, if acceleration were to occur for other reasons, the realizable value at the acceleration date

of the money and government obligations in the defeasance trust could be less than the principal and interest then due on the debt securities of such series, in that the required deposit in the defeasance trust is based upon scheduled cash flows rather than market value, which will vary depending upon interest rates and other factors.

Notices

Notices to holders of debt securities will be given by mail to the addresses of such holders as they appear in the security register.

Title

We, the Trustee and any agent of ours may treat the registered owner of any registered debt security as the absolute owner thereof (whether or not the debt security shall be overdue and notwithstanding any notice to the contrary) for the purpose of making payment and for all other purposes.

Replacement of Debt Securities

We will replace any mutilated debt security at the expense of the holders upon surrender to the Trustee. We will replace debt securities that become destroyed, lost or stolen at the expense of the holder upon delivery to the Trustee of satisfactory evidence of the destruction, loss or theft thereof. In the event of a destroyed, lost or stolen debt security, an indemnity or security satisfactory to us and the Trustee may be required at the expense of the holder of the debt security before a replacement debt security will be issued.

Governing Law

The Indenture and the debt securities will be governed by, and construed in accordance with, the laws of the State of New York.

Concerning the Trustee

Viacom will identify the Trustee in the relevant prospectus supplement. In specific instances, Viacom or the holders of a majority of the then outstanding principal amount of the debt securities issued under the Indenture may remove the Trustee and appoint a successor trustee. The Trustee may become the owner or pledgee of any of the debt securities with the same rights, subject to conflict of interest restrictions, it would have if it were not the Trustee. The Trustee and any successor trustee must be eligible to act as trustee under Section 310(a)(1) of the Trust Indenture Act of 1939 and shall have a combined capital and surplus of at least $50,000,000 and be subject to examination by federal or state authority. Subject to applicable law relating to conflicts of interest, the Trustee may also serve as trustee under other indentures relating to securities issued by Viacom or its affiliated companies and may engage in commercial transactions with Viacom and its affiliated companies. The initial Trustee under the Indenture is The Bank of New York.

Subordination

In addition to the provisions previously described in this prospectus and applicable to all debt securities, the following description of any senior subordinated debt securities summarizes the additional terms and provisions of such senior subordinated debt securities to which any prospectus supplement may relate. The specific terms of Viacom’s senior subordinated debt securities offered by any prospectus supplement and the extent, if any, to which the general provisions summarized below may apply to any series of senior subordinated debt securities will be described in the prospectus supplement relating to that series.

Any senior subordinated debt securities will be subordinated in right of payment to Viacom’s senior indebtedness to the extent set forth in the applicable prospectus supplement.

The payment of the principal of, premium, if any, and interest on any senior subordinated debt securities will be subordinated in right of payment to the prior payment in full of all of Viacom’s senior indebtedness. Viacom may not make payment of principal, premium, if any, sinking funds or interest, if any, on any senior subordinated debt securities unless full payment of amounts then due for principal, premium, if any, sinking funds and interest on all senior indebtedness has been made or duly provided for.

For purposes of the description of any senior subordinated debt securities, the term “Senior Indebtedness” of the Company means all indebtedness of the Company, except (a) Indebtedness that, pursuant to its terms, is subordinated in right of payment to other Indebtedness and (b) Indebtedness evidenced by an instrument that expressly provides that such Indebtedness is not Senior Indebtedness. Notwithstanding anything to the contrary in the foregoing, Senior Indebtedness will not include any liability for taxes owed or owing by the Company or any trade payables.

As of September 30, 2006, a total of approximately $7.84 billion of Viacom’s indebtedness was Senior Indebtedness.

Certain Definitions

The following definitions are applicable to the Indenture:

“Capitalized Lease” means any obligation of a person to pay rent or other amounts incurred with respect to real property or equipment (other than in respect of telecommunications equipment including, without limitation, satellite transponders) acquired or leased by such person and used in its business that is required to be recorded as a capital lease in accordance with generally accepted accounting principles consistently applied as in effect from time to time.

DESCRIPTION OF PREFERRED STOCK

The following description sets forth certain general terms of preferred stock that Viacom may offer. The terms of any series of the preferred stock will be described in the applicable prospectus supplement relating to the preferred stock being offered. The description set forth below and in any prospectus supplement is not complete, and is subject to, and qualified in its entirety by reference to, Viacom’s amended and restated certificate of incorporation, and the certificate of designations relating to each particular series of the preferred stock, which was or will be filed with the SEC at or before the issuance of the series of preferred stock. References to “Viacom” in this description are references to Viacom Inc. and not its consolidated subsidiaries, unless the context otherwise requires.

Terms of the Preferred Stock

Under Viacom’s amended and restated certificate of incorporation, Viacom is authorized to issue up to 25,000,000 shares of preferred stock, par value $0.001 per share. The Board of Directors of Viacom has the authority, without approval of the stockholders to cause shares of preferred stock to be issued from time to time in one or more series, with the numbers of shares of each series and the designations, preferences and relative, participating, optional, dividend and other special rights of the shares of each such series and the qualifications, limitations, restrictions, conditions and other characteristics thereof as fixed by the Board of Directors. As of September 30, 2006, Viacom had 25,000,000 shares of preferred stock available for issuance.

The applicable prospectus supplement will describe the terms of each series of preferred stock, including, where applicable, the following:

•

the designation, stated value, liquidation preference and number of shares offered;

•

the offering price(s);

•

the dividend rate(s), or method of calculation, the dividend periods, the date on which dividends shall be payable and whether dividends are cumulative or noncumulative and, if cumulative, the dates from which dividends begin to accumulate;

•

any redemption or sinking fund provisions;

•

any conversion or exchange provisions;

•

any voting rights;

•

whether the preferred stock will be issued in certificated or book-entry form;

•

whether the preferred stock will be listed on a national securities exchange;

•

information with respect to any book-entry procedures;

•

a discussion of any material United States federal income tax and other special considerations, procedures and limitations relating to the preferred stock; and

•

any additional rights, preferences, privileges, limitations and restrictions of the preferred stock which are not inconsistent with the provisions of the amended and restated certificate of incorporation.

The preferred stock will be, when issued against payment, fully paid and nonassessable. Holders will have no preemptive rights to subscribe for any additional securities that Viacom may issue. Unless otherwise specified in the applicable prospectus supplement, the shares of each series of preferred stock will rank equally with all other outstanding series of preferred stock issued by Viacom as to payment of dividends, other than with respect to cumulation of dividends, and as to the distribution of assets upon liquidation, dissolution, or winding up of Viacom. As of September 30, 2006, there were no shares of Viacom’s preferred stock outstanding. Each series of preferred stock will rank senior to the common stock and any other stock of Viacom that is expressly made junior to that series of preferred stock. However, the Board of Directors may not issue any preferred stock, or preferred

stock that is convertible into or exchangeable for other securities, that, in the aggregate with all other outstanding shares of preferred stock, could elect a majority of the Board of Directors, unless such issuance has been approved by the holders of a majority of the outstanding shares of Viacom class A common stock, voting separately as a class.

Unless otherwise specified in the applicable prospectus supplement, The Bank of New York will be the transfer agent, dividend disbursing agent and registrar for the shares of the preferred stock.

Viacom’s rights and the rights of holders of Viacom securities, including the holders of preferred stock, to participate in the distribution of assets of any subsidiary of Viacom upon its liquidation or recapitalization will be subject to the prior claims of the subsidiary’s creditors and preferred stockholders, except to the extent Viacom may itself be a creditor with recognized claims against the subsidiary or a holder of preferred stock of the subsidiary.

Dividends and Distributions

Unless otherwise specified in the prospectus supplement, holders of shares of the preferred stock will be entitled to receive, as, if and when declared by the Board of Directors of Viacom or a duly authorized committee of the Board of Directors, out of funds legally available for the payment of dividends, cash dividends at the rate set forth in, or calculated in accordance with the formula set forth in, the prospectus supplement relating to the preferred stock being offered. Dividends on the preferred stock may be cumulative or noncumulative as provided in the applicable prospectus supplement. Dividends on the cumulative preferred stock will accumulate from the date of original issue and will be payable as specified in the applicable prospectus supplement. The applicable prospectus supplement will set forth the applicable dividend period with respect to a dividend payment date. If the Board of Directors of Viacom or a duly authorized committee of the Board of Directors fails to declare a dividend on any series of noncumulative preferred stock for any dividend period, Viacom will have no obligation to pay a dividend for that period, whether or not dividends on that series of noncumulative preferred stock are declared for any future dividend period.

No dividends will be declared or paid or set apart for payment on the preferred stock of any series ranking, as to dividends, equally with or junior to any other series of preferred stock for any period unless dividends have been or are contemporaneously declared and paid or declared and a sum sufficient for the payment of those dividends has been set apart for:

•

in the case of cumulative preferred stock, all dividend periods terminating on or before the date of payment of full cumulative dividends; or

•

in the case of noncumulative preferred stock, the immediately preceding dividend period.

When dividends are not paid in full upon any series of preferred stock, and any other preferred stock ranking equally as to dividends with that series of preferred stock, all dividends declared upon shares of that series of preferred stock and any other preferred stock ranking equally as to dividends will be declared pro rata so that the amount of dividends declared per share on that series of preferred stock and any other preferred stock ranking equally as to dividends will in all cases bear to each other the same ratio that accrued dividends per share on the shares of that series of preferred stock and the other preferred stock bear to each other. In the case of noncumulative preferred stock, any accrued dividends described in the immediately preceding paragraph will not include any cumulation in respect of unpaid dividends for prior dividend periods.

Except as provided in the immediately preceding paragraph or the applicable prospectus supplement, unless full dividends on all outstanding shares of any series of preferred stock have been declared and paid, in the case of a series of cumulative preferred stock, for all past dividend periods, or in the case of noncumulative preferred stock, for the immediately preceding dividend period, Viacom may not declare dividends or pay or set aside for payment or other distribution on any of its capital stock ranking junior to or equally with that series of preferred

stock as to dividends or upon liquidation, other than dividends or distributions paid in shares of, or options, warrants or rights to subscribe for or purchase shares of, the common stock of Viacom or other capital stock of Viacom ranking junior to that series of preferred stock as to dividends and upon liquidation. Other than in connection with the distribution or trading of any of its capital stock, Viacom may not redeem, purchase or otherwise acquire any of its capital stock ranking junior to or equally with that series of preferred stock as to dividends or upon liquidation, for any consideration or any moneys paid to or made available for a sinking fund for the redemption of any shares of any of its capital stock, except by conversion or exchange for capital stock of Viacom ranking junior to that series of preferred stock as to dividends and upon liquidation.

Unless otherwise specified in the applicable prospectus supplement, the amount of dividends payable for any period shorter than a full dividend period shall be computed on the basis of twelve 30-day months, a 360-day year and the actual number of days elapsed in any period of less than one month.

Liquidation Preference

Unless otherwise specified in the applicable prospectus supplement, upon any voluntary or involuntary liquidation, dissolution or winding up of Viacom, the holders of the preferred stock will have preference and priority over the common stock of Viacom and any other class of stock of Viacom ranking junior to the preferred stock upon liquidation, dissolution or winding up, for payments out of or distributions of the assets of Viacom or proceeds from any liquidation, of the amount per share set forth in the applicable prospectus supplement plus all accrued and unpaid dividends, to the date of final distribution to such holders. After any liquidating payment, the holders of preferred stock will not be entitled to any other payments.

Redemption

If specified in the prospectus supplement relating to a series of preferred stock being offered, Viacom may, at its option, at any time or from time to time, redeem that series of preferred stock, in whole or in part, at the redemption prices and on the dates set forth in the applicable prospectus supplement.

If less than all outstanding shares of a series of preferred stock is to be redeemed, the selection of the shares to be redeemed shall be determined by lot or pro rata as may be determined to be equitable by the Board of Directors of Viacom or a duly authorized committee of the Board of Directors. From and after the redemption date, unless Viacom is in default in providing for the payment of the redemption price, dividends shall cease to accrue on the shares of that series of preferred stock called for redemption and all rights of the holders shall cease, other than the right to receive the redemption price.

Voting Rights

Unless otherwise described in the applicable prospectus supplement, holders of the preferred stock will have no voting rights except as required by law.

Conversion or Exchange Rights

The prospectus supplement relating to a series of preferred stock that is convertible or exchangeable will state the terms on which shares of that series are convertible or exchangeable into common stock, another series of preferred stock or debt securities.

DESCRIPTION OF COMMON STOCK

The authorized common stock of Viacom as set forth in its amended and restated certificate of incorporation includes 375,000,000 shares of Viacom class A common stock, par value $0.001 per share, and 5,000,000,000 shares of Viacom class B common stock, par value $0.001 per share. Viacom is not registering with the SEC and is therefore not permitted to offer or sell any shares of Viacom class A common stock pursuant to the registration statement of which this prospectus is a part. Viacom is only registering with the SEC shares of Viacom class B common stock as may from time to time be issued upon conversion of debt securities or preferred stock. References to “Viacom” in this description are references to Viacom Inc. and not its consolidated subsidiaries, unless the context otherwise requires.

The descriptions set forth below and in any prospectus supplement are not complete, and are subject to, and qualified in their entirety by reference to, Viacom’s amended and restated certificate of incorporation and bylaws and the Delaware General Corporation Law.

General

All issued and outstanding shares of Viacom class A common stock and Viacom class B common stock are identical and the holders of such shares are entitled to the same rights and privileges, except as provided in Viacom’s amended and restated certificate of incorporation as described below.

Voting Rights. Holders of Viacom class A common stock are entitled to one vote per share with respect to all matters on which the holders of Viacom common stock are entitled to vote and the affirmative vote of a majority of the outstanding shares of Viacom class A common stock, voting separately as a class, is necessary to approve any merger or consolidation of Viacom pursuant to which shares of Viacom common stock are converted into or exchanged for any other securities or consideration.

Holders of Viacom class B common stock do not have any voting rights, except as required by Delaware law.

Generally, all matters to be voted on by the stockholders of Viacom must be approved by a majority of the aggregate voting power of the shares of capital stock of Viacom present in person or represented by proxy, except as required by Delaware law.

Dividends. Holders of Viacom class A common stock and Viacom class B common stock share ratably in any cash dividend declared by the Board of Directors, subject to any preferential rights of any outstanding preferred stock. If the Board of Directors declares a dividend of any securities of Viacom or another entity, the Board of Directors will determine whether the holders of Viacom class A common stock and Viacom class B common stock are to receive identical securities or to receive different classes or series of securities, but only to the extent such differences are consistent in all material respects with any differences between Viacom class A common stock and Viacom class B common stock.

Conversion. So long as there are 5,000 shares of Viacom class A common stock outstanding, each share of Viacom class A common stock is convertible at the option of the holder of such share into one share of Viacom class B common stock.

Liquidation Rights. In the event of a liquidation, dissolution or winding-up of Viacom, all holders of Viacom common stock, regardless of class, are entitled to share ratably in any assets available for distributions to holders of shares of Viacom common stock subject to the preferential rights of any outstanding preferred stock.

Split, Subdivision or Combination. In the event of a split, subdivision or combination of the outstanding shares of Viacom class A common stock or Viacom class B common stock, the outstanding shares of the other class of Viacom common stock will be divided proportionally.

Preemptive Rights. Shares of Viacom class A common stock and Viacom class B common stock do not entitle a holder to any preemptive rights enabling a holder to subscribe for or receive shares of stock of any class or any other securities convertible into shares of stock of any class of Viacom. The Board of Directors possesses the power to issue shares of authorized but unissued Viacom class A common stock and Viacom class B common stock without further stockholder action, subject to the requirements of applicable law and stock exchanges. The number of authorized shares of Viacom class A common stock and Viacom class B common stock could be increased with the approval of the holders of a majority of the outstanding shares of Viacom class A common stock and without any action by the holders of shares of Viacom class B common stock.

Other Rights. Viacom’s amended and restated certificate of incorporation provides that Viacom may prohibit the ownership of, or redeem, shares of its capital stock in order to ensure compliance with, or prevent the applicability of limitations imposed by, the requirements of U.S. laws or regulations applicable to specified types of media companies.

DESCRIPTION OF WARRANTS

The following description sets forth certain general terms of warrants that Viacom may offer. Viacom may issue warrants for the purchase of its debt securities or shares of preferred stock. Warrants may be issued independently or together with any debt securities or shares of preferred stock offered by any prospectus supplement and may be attached to or separate from debt securities or shares of preferred stock. The warrants are to be issued under warrant agreements to be entered into among Viacom and The Bank of New York, as warrant agent, or such other bank or trust company as is named in the prospectus supplement relating to the particular issue of warrants. The warrant agent will act solely as an agent of Viacom in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any holders of warrants or beneficial owners of warrants. The description set forth below and in any prospectus supplement is not complete and is subject to, and qualified in its entirety by reference to, any warrant agreement pursuant to which warrants may be issued. References to “Viacom” in this description are references to Viacom Inc. and not its consolidated subsidiaries, unless the context otherwise requires.

General

If warrants are offered, the prospectus supplement will describe the terms of the warrants, including the following:

•

the offering price;

•

the currency unit(s) for which warrants may be purchased;

•

the designation, aggregate principal amount, currency unit(s) and terms of debt securities which may be purchased upon such exercise;

•

the designation, number of shares and terms of the preferred stock purchasable upon exercise of the preferred stock warrants and the price at which the shares of preferred stock may be purchased upon such exercise;

•

if applicable, the designation and terms of debt securities or preferred stock with which the warrants are issued and the number of warrants issued with each debt security or share of preferred stock;

•

if applicable, the date on and after which the warrants and the related debt securities or preferred stock will be separately transferable;

•

the date on which the right to exercise the warrants will commence and the date on which the right will expire;

•

whether the warrants will be issued in registered or bearer form;

•

a discussion of any material United States federal income tax and other special considerations, procedures and limitations relating to the warrants; and

•

any other terms of the warrants.

Warrants may be exchanged for new warrants of different denominations. If in registered form, the warrants may be presented for registration of transfer. The warrants may be exercised at the corporate trust office of the warrant agent or any other office indicated in the prospectus supplement. Before the exercise of their warrants, holders of warrants will not have any of the rights of holders of the various securities purchasable upon the exercise, including the right to receive payments of principal of, any premium on, or any interest on debt securities purchasable upon the exercise or to enforce the covenants in the applicable indenture or to receive payments of dividends, if any, on the preferred stock purchasable upon their exercise or to exercise any applicable right to vote. If Viacom maintains the ability to reduce the exercise price of any preferred stock warrant and the right is triggered, it will comply with federal securities laws, including Rule 13e-4 under the Exchange Act, to the extent applicable.

Exercise of Warrants

Each warrant will entitle the holder to purchase a principal amount of debt securities or a number of shares of preferred stock at the exercise price as will in each case be set forth in, or calculable from, the prospectus supplement relating to the warrant. Warrants may be exercised at the times that are set forth in the prospectus supplement relating to the warrants. After the close of business on the date on which the warrant expires, or any later date to which Viacom may extend the expiration date, unexercised warrants will become void.

Subject to any restrictions and additional requirements that may be set forth in the prospectus supplement relating thereto, warrants may be exercised by delivery to the warrant agent of the certificate evidencing the warrants properly completed and duly executed and of payment as provided in the prospectus supplement of the amount required to purchase the debt securities or shares of preferred stock purchasable upon the exercise. The exercise price will be the price applicable on the date of payment in full, as set forth in the prospectus supplement relating to the warrants. Upon receipt of the payment and the certificate representing the warrants to be exercised, properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the prospectus supplement, Viacom will, as soon as practicable, issue and deliver the debt securities or shares of preferred stock purchasable upon the exercise. If fewer than all of the warrants represented by a certificate are exercised, a new certificate will be issued for the remaining amount of warrants.

Additional Provisions

The exercise price payable and the number of shares of preferred stock purchasable upon the exercise of each stock warrant will be subject to adjustment in specific events, including the issuance of a stock dividend to holders of preferred stock, or a combination, subdivision or reclassification of preferred stock. In lieu of adjusting the number of shares of preferred stock purchasable upon exercise of each stock warrant, Viacom may elect to adjust the number of preferred stock warrants. No adjustment in the number of shares purchasable upon exercise of the preferred stock warrants will be required until cumulative adjustments require an adjustment of at least 1% thereof. Viacom may, at its option, reduce the exercise price at any time. No fractional shares will be issued upon exercise of preferred stock warrants, but Viacom will pay the cash value of any fractional shares otherwise issuable. In case of any consolidation, merger, or sale or conveyance of the property of Viacom as an entirety or substantially as an entirety, the holder of each outstanding preferred stock warrant will have the right upon the exercise to the kind and amount of shares of stock and other securities and property, including cash, receivable by a holder of the number of shares of preferred stock into which the stock warrants were exercisable immediately prior thereto.

No Rights as Shareholders

Holders of preferred stock warrants will not be entitled, by virtue of being the holders, to vote, to consent, to receive dividends, to receive notice as shareholders with respect to any meeting of shareholders for the election of the directors or any other matter, or to exercise any rights whatsoever as its shareholders, with respect to Viacom.
