CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS This prospectus and the documents incorporated by reference into this prospectus contain both historical and forward-looking statements. All statements other than statements of historical fact are, or may be deemed to be, forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act of 1934. These forward-looking statements are not based on historical facts, but rather reflect our current expectations concerning future results and events. These forward-looking statements generally can be identified by the use of statements that include phrases such as "believe," "expect," "anticipate," "intend," "plan," "foresee," "likely," "will" or other similar words or phrases. Similarly, statements that describe our objectives, plans or goals are or may be forward-looking statements. These forward-looking statements involve known and unknown risks, uncertainties and other factors which may cause our actual results, performance or achievements to be different from any future results, performance and achievements expressed or implied by these statements. You should review carefully all information, including the financial statements and the notes to the financial statements, included or incorporated by reference into this prospectus. The following important factors, among others, could affect our future results, causing these results to differ materially from those expressed in our forward-looking statements: o We derive substantial revenues from the sale of advertising time on our over-the-air networks, basic cable networks, television stations, radio stations and outdoor businesses. The advertising market has recently experienced softness. The sale of advertising time is affected by viewer demographics, viewer ratings and market conditions for advertising time. Adverse changes to any of these factors could have a negative effect on revenues. o Operating results derived from our motion picture and television production fluctuate depending primarily upon cost of such productions and acceptance of such productions by the public, which are difficult to predict. Motion picture and television production has experienced cycles in which increased costs of talent and other factors have resulted in higher production costs. In addition, the commercial success of our motion picture and television productions also depends upon the quality and acceptance of other competing productions, and the availability of alternative forms of entertainment and leisure time activities. o Our operating results also fluctuate due to the timing and availability of theatrical and home video releases, as well as a result of the recording of license fees for television exhibition of motion pictures and for syndication and basic cable exhibition of television programming in the period that the products are available for such exhibition. o Our basic cable network and premium subscription television networks are dependent on affiliation agreements with cable and direct broadcast satellite distributors on acceptable terms. The loss of carriage on such distributors, or continued carriage on less favorable terms, could adversely affect, with respect to basic cable networks, revenues from subscriber fees and the ability to sell advertising time, and with respect to premium subscription television networks, subscriber fee revenues. o Some of our businesses are seasonal. More specifically, the home video business and consumer publishing business are subject to increased periods of demand coinciding with summer and winter holidays, while a substantial majority of the theme parks operating income is generated from May through September. In addition, the home video and theme parks businesses' revenues are influenced by weather. o Changes in FCC laws and regulations could, directly or indirectly, adversely affect the operations and ownership of our properties. o We have contingent liabilities related to discontinued operations, including environmental liabilities and pending litigation. While there can be no assurance in this regard, the pending or potential litigation, environmental and other liabilities should not have a material adverse effect on us. o We may be adversely affected by changes in technology and its effect on competition in our markets. o Labor agreements covering the services of writers and actors which we utilize in our motion picture and television businesses are currently scheduled to expire during 2001. Work stoppages and/or higher costs in connection with these agreements could adversely impact our ability to produce or acquire new programming. o Other economic, business, competitive and/or regulatory factors affecting our businesses generally. These factors are not necessarily all of the important factors that could cause actual results to differ materially from those expressed in any of our forward-looking statements. Other unknown or unpredictable factors also could have material adverse effects on our future results. The forward-looking statements included in this prospectus are made only as of the date of this prospectus and under Section 27A of the Securities Act and Section 21E of the Exchange Act and we do not have any obligation to publicly update any forward-looking statements to reflect subsequent events or circumstances. We cannot assure you that projected results or events will be achieved.

Together the 2001 senior debt trustee and the 2001 senior subordinated debt trustee are called the 2001 debt trustees and together the 2001 debt trustees and the 1995 senior debt trustee are called to as the "debt trustees". None of the indentures limit the amount of debt securities that may be issued. The applicable 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 will issue debt securities from time to time and offer its debt securities on terms 4

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, 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 their stated principal amount. Viacom will describe the material 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: o the designation, aggregate principal amount and authorized denominations of the debt securities; o the percentage of the principal amount at which Viacom will issue the debt securities; o the date or dates on which the debt securities will mature; o the annual interest rate or rates of the debt securities, or the method of determining the rate or rates; o the date or dates on which any interest will be payable, the date or dates on which payment of any interest will commence and the regular record dates for the interest payment dates; o whether the debt securities will be guaranteed by Viacom International; o the terms of any mandatory or optional redemption, including any provisions for any sinking, purchase or other similar funds, or repayment options; o the currency, currencies or currency units for which the debt securities may be purchased and in which the principal, any premium and any interest may be payable; o if the currency, currencies or currency units 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; o if the amount of payments on the debt securities is determined by an index based on one or more currencies or currency units, or changes in the price of one or more securities or commodities, the manner in which the amounts may be determined; o 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; o the terms and conditions upon which the debt securities may be convertible into or exchanged for common stock, preferred stock, or indebtedness or other securities of any person, including Viacom; o information with respect to book-entry procedures, if any; o a discussion of any material federal income tax and other special considerations, procedures and limitations relating to the debt securities; and 5

o any other specific terms of the debt securities not inconsistent with the applicable debt 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 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 on, and interest on the debt securities will be payable, and the debt securities will be transferable, at the corporate trust office of the applicable debt 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 debt 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 or 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. Guarantees Viacom International may unconditionally guarantee the due and punctual payment of the principal of, premium, if any, and any interest on the debt securities when and as the same shall become due and payable, whether at maturity, upon redemption, upon acceleration or otherwise. The guarantees of the debt securities will be endorsed on the debt securities. Various federal and state fraudulent conveyance laws have been enacted for the protection of creditors and may be utilized by a court of competent jurisdiction to subordinate or avoid all or part of any guarantee issued by Viacom International. The applicable debt indentures provide that in the event that the guarantees would constitute or result in a fraudulent transfer or conveyance for purposes of, or result in a violation of, any United States federal, or applicable United States state, fraudulent transfer or conveyance or similar law, then the liability of Viacom International under the guarantees shall be reduced to the extent necessary to eliminate such fraudulent transfer or conveyance or violation under the applicable fraudulent transfer or conveyance or similar law. Application of this clause could limit the amount which holders of debt securities may be entitled to collect under the guarantees. Holders, by their acceptance of the debt securities, will have agreed to such limitations. To the extent that a court were to find that (x) a guarantee was incurred by Viacom International with the intent to hinder, delay or defraud any present or future creditor (y) Viacom International did not receive fair consideration or reasonably equivalent value for issuing its guarantee and Viacom International (i) was insolvent or rendered insolvent by reason of the issuance of the guarantee, (ii) was engaged or about to engage in a business or transaction for which the remaining assets of Viacom 6

International constituted unreasonably small capital to carry on its business or (iii) intended to incur, or believed that it would incur, debts beyond its ability to pay such debts as they matured, the court could subordinate or avoid all or part of such guarantee in favor of Viacom International's other creditors. To the extent any guarantee issued by Viacom International was voided as a fraudulent conveyance or held unenforceable for any other reason, the holders of any debt securities guaranteed by Viacom International could cease to have any claim against Viacom International and would be creditors solely of Viacom. We and Viacom International believe that the issuances of the guarantees by Viacom International are not fraudulent conveyances. There can be no assurance, however, that a court passing on such questions would reach the same conclusions. In rendering their opinions on the validity of the 2001 senior debt securities, 2001 senior subordinated securities and 1995 senior securities and, if applicable, the related guarantees, neither our counsel, counsel for Viacom International nor counsel for any initial purchaser will express any opinion as to federal or state laws relating to fraudulent transfers. Ranking The 2001 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. The guarantees on the 2001 senior debt securities will be senior unsecured obligations of Viacom International and will rank equally in right of payment with all of Viacom International's other unsecured and unsubordinated indebtedness. The 2001 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. The guarantees on the 2001 senior subordinated debt securities will be senior unsecured subordinated obligations of Viacom International and will be subordinated in right of payment to Viacom International's senior indebtedness. The 1995 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. The guarantees on the 1995 senior debt securities will be senior unsecured obligations of Viacom International and will rank equally in right of payment will all of Viacom International's other unsecured and unsubordinated indebtedness. The debt securities and the guarantees will be effectively subordinated to any secured indebtedness of Viacom or Viacom International, as the case may be, to the extent of the value of the assets securing such indebtedness. The debt indentures do not limit the amount of debt that Viacom, Viacom International or their respective subsidiaries can incur. In addition, both Viacom International and Viacom conduct their operations through subsidiaries, which generate a substantial portion of their respective operating income and cash flow. As a result, distributions or advances from subsidiaries of Viacom and Viacom International are a major source of funds necessary to meet their respective debt service and other obligations. Contractual provisions, laws or regulations, as well as a subsidiaries' financial condition and operating requirements, may limit the ability of Viacom or Viacom International to obtain cash required to pay Viacom's debt service obligations, including payments on the debt securities, or Viacom International's payment obligations under the guarantees. The debt securities (whether senior or subordinated obligations of Viacom) will be structurally subordinated to all obligations of Viacom's subsidiaries (other than Viacom International, to the extent such debt securities are guaranteed) including claims with respect to trade payables. The guarantees (whether senior or subordinated obligations of Viacom International) will be structurally subordinated to all obligations of Viacom International'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 7

claims of creditors of Viacom's subsidiaries (other than Viacom International, to the extent such debt securities are guaranteed) on the assets and earnings of such subsidiaries. Holders of guarantees of Viacom International, if any, will have a junior position to the claims of creditors of Viacom International's subsidiaries on the assets and earnings of such subsidiaries and will have no claim by virtue of such guarantees against Viacom or any subsidiary of Viacom that is not a subsidiary of Viacom International. As of March 31, 2001, Viacom's subsidiaries, other than Viacom International, had approximately $2.3 billion of indebtedness outstanding, while Viacom International's subsidiaries had approximately $1.4 billion 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: o the applicable depositary or its nominee, with respect to interests of depositary participants; and o the records of depositary participants, with respect to interests of persons other than depositary participants. The laws of some states require that purchasers of securities take physical delivery of the securities in definitive form. These laws may impair the ability to transfer beneficial interests in a global security. 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: o not be entitled to have any of the individual debt securities of the series represented by the global security registered in their names; 8

o not receive or be entitled to receive physical delivery of any debt security of that series in definitive form; and o not be considered the owners or holders thereof under the applicable 2001 debt indenture governing the debt securities. 9

DESCRIPTION OF THE 2001 DEBT SECURITIES Further Issues Not all 2001 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 2001 debt securities of such series. Payment and Paying Agents Payments of principal of, any premium on, and any interest on individual 2001 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 2001 debt securities. Neither Viacom, the 2001 debt trustee, any paying agent, nor the security registrar for the 2001 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 2001 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 2001 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 2001 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 2001 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 2001 debt indentures, Viacom and Viacom International 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 and Viacom International meeting all of the following conditions: o the resulting entity (other than Viacom or Viacom International) must agree through a supplemental indenture to be legally responsible for the 2001 debt securities; o immediately following the consolidation, merger, sale or conveyance, no Event of Default (as defined below) shall have occurred and be continuing; o the surviving entity to the transaction must be a corporation organized under the laws of a state of the United States; o Viacom or Viacom International, as the case may be, must deliver certain certificates and documents to the 2001 debt trustee; and o Viacom and Viacom International, if applicable, must satisfy any other requirements specified in the prospectus supplement relating to a particular series of 2001 debt securities. 10

We and Viacom International may merge or consolidate with, or sell all or substantially all of our assets to each other or any of our Subsidiaries. When we make reference in this section to the sale of "all or substantially all of our assets," we mean property and assets generating revenues representing, in the aggregate, at least 80% of our total consolidated revenues. In the event that Viacom or Viacom International 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 or Viacom International, as the case may be, under the 2001 debt indentures and Viacom or Viacom International, as the case may be, shall be discharged from all of its obligations under the 2001 debt indentures. Limitations on Liens We covenant in the 2001 debt indentures that we will not create, assume or permit any Lien on any of our properties or assets, unless we secure the 2001 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: o Liens existing, in the case of any 2001 debt securities, on the date such 2001 debt securities are issued; o 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); o Liens in favor of us or our Subsidiaries; and o 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 2001 debt indentures 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 2001 debt securities are issued or that exist at the time any person that owns a Principal Property becomes a Restricted Subsidiary) which has been or is to be sold by us or the Restricted Subsidiary to the person unless: o the sale and leaseback arrangement involves a lease for a term of not more than three years; o the sale and leaseback arrangement is entered into between us and any Subsidiary or between our Subsidiaries; o 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 11

pursuant to the first paragraph under "Limitations on Liens" without having to secure equally and ratably the 2001 debt securities; o 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 2001 debt securities and that is not debt to us or a Subsidiary, or (ii) the purchase or development of other comparable property; or o 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 2001 debt indentures 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 2001 debt indentures. The term "Principal Property" is defined in the 2001 debt indentures 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 $1.0 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 2001 debt securities will have specified rights if an Event of Default (as defined below) occurs in respect of the 2001 debt securities of that series, as described below. The term "Event of Default" in respect of the 2001 debt securities of a particular series means any of the following: o Viacom does not pay interest on a 2001 debt security of such series within 30 days of its due date; o Viacom does not pay the principal of or any premium on a 2001 debt security of such series when due and payable, at its maturity, or upon its acceleration or redemption; o Viacom remains in breach of a covenant or warranty in respect of an indenture for 60 days after Viacom receives a written notice of default; the notice must be sent by either the 2001 debt trustee or holders of at least 25% in principal amount of a series of outstanding 2001 debt securities; or 12

o Viacom or Viacom International, if guarantees are issued, files for bankruptcy, or other events of bankruptcy specified in the applicable 2001debt indenture, insolvency or reorganization occur. If an Event of Default has occurred, the 2001 debt trustee or the holders of at least 25% in principal amount of the 2001 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 2001 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 2001 debt trustee or any holder of 2001 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 2001 debt securities of a series may also waive certain past defaults under the 2001 debt indenture on behalf of all of the holders of such series of 2001 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 2001 debt securities and the 2001 debt trustee. Except in cases of default, where the 2001 debt trustee has special duties, a 2001 debt trustee is not required to take any action under a 2001 debt indenture at the request of holders unless the holders offer the 2001 debt trustee reasonable protection from expenses and liability satisfactory to the 2001 debt trustee. If a reasonable indemnity is provided, the holders of a majority in principal amount of a series of 2001 debt securities may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the debt trustee. The 2001 debt trustee may refuse to follow those directions in certain circumstances specified in the applicable 2001 debt 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 2001 debt 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 2001 debt securities, the following must occur: o holders must give the 2001 debt trustee written notice that an Event of Default has occurred and remains uncured; o holders of at least 25% in principal amount of the outstanding 2001 debt securities of a series must make a written request that the 2001 debt trustee take action because of the default and must offer the 2001 debt trustee indemnity satisfactory to the 2001 debt trustee against the cost and other liabilities of taking that action; o the 2001 debt trustee must have failed to take action for 60 days after receipt of the notice and offer of indemnity; and o holders of a majority in principal amount of the 2001 debt securities of a series must not have given the 2001 debt trustee a direction inconsistent with the above notice for a period of 60 days after the debt trustee has received the notice. Holders are, however, entitled at any time to bring a lawsuit for the payment of money due on the 2001 debt securities on or after the due date. Modification of the 2001 Debt Indentures The 2001 debt indentures provide that Viacom, Viacom International, if applicable, and the 2001 debt trustee may, without the consent of any holders of 2001 debt securities, enter into supplemental indentures for the purposes, among other things, of: 13

o adding to Viacom's or Viacom International's covenants; o adding additional events of default; o change or eliminate any provisions of the 2001 debt indenture so long as there are no holders entitled to the benefit of the provisions; o establishing the form or terms of any series of 2001 debt securities; or o curing ambiguities or inconsistencies in the 2001 debt indenture or making any other provisions with respect to matters or questions arising under the 2001 debt indentures. With specific exceptions, the 2001 debt indenture or the rights of the holders of the 2001 debt securities may be modified by Viacom, Viacom International and the 2001 debt trustee with the consent of the holders of a majority in aggregate principal amount of the 2001 debt securities of each series affected by the modification then outstanding, but no modification may be made without the consent of the holders of each outstanding 2001 debt security affected which would: o change the maturity of any payment of principal of, or any premium on, or any installment of interest on any 2001 debt security; o change the terms of any sinking fund with respect to any 2001 debt security; o reduce the principal amount of, or the interest or any premium on, any 2001 debt security upon redemption or repayment at the option of the holder; o change any obligation of Viacom to pay additional amounts; o change any place of payment where, or the currency in which, any 2001 debt security or any premium or interest is payable; o impair the right to sue for the enforcement of any payment on or with respect to any 2001 debt security; o reduce the percentage in principal amount of outstanding 2001 debt securities of any series required to consent to any supplemental indenture, any waiver of compliance with provisions of a 2001 debt indenture or specific defaults and their consequences provided for in the 2001 debt indenture, or otherwise modify the sections in the 2001 debt indenture relating to these consents; or o reduce the obligations of Viacom International, if any, in respect of the due and punctual payment of principal, premium and interest, if any. Defeasance and Covenant Defeasance Viacom may elect either (i) to defease and be discharged (and, if applicable, to have Viacom International defeased and discharged) from any and all obligations with respect to the 2001 debt securities (except as otherwise provided in the 2001 debt indenture) ("defeasance") or (ii) to be released from its obligations with respect to certain covenants that are described in the 2001 debt indentures ("covenant defeasance"), upon the deposit with the 2001 debt trustee, in trust for such purpose, of money and/or government obligations that through the payment of principal and interest in accordance with their 14

terms will provide money in an amount sufficient, without reinvestment, to pay the principal of, premium, if any, and interest on the 2001 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 2001 debt trustee an opinion of counsel to the effect that the holders of the 2001 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 2001 debt indenture. Viacom may exercise its defeasance option with respect to the 2001 debt securities of any series notwithstanding its prior exercise of its covenant defeasance option. If Viacom exercises its defeasance option, payment of the 2001 debt securities of such series may not be accelerated because of an event of default and the guarantees relating to such 2001 debt securities will cease to exist. If Viacom exercises its covenant defeasance option, payment of the 2001 debt securities of such series may not be accelerated by reference to any covenant from which Viacom is released as described under clause (ii) above. 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 2001 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 2001 debt securities will be given by mail to the addresses of such holders as they appear in the security register. Title We, Viacom International, as guarantor, the 2001 debt trustees and any agent of us, may treat the registered owner of any registered 2001 debt security as the absolute owner thereof (whether or not the 2001 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 2001 Debt Securities We will replace any mutilated 2001 debt security at the expense of the holders upon surrender to the trustee. We will replace 2001 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 2001 debt security, an indemnity or security satisfactory to us and the 2001 debt trustee may be required at the expense of the holder of the 2001 debt security before a replacement 2001 debt security will be issued. Governing Law The 2001 debt indentures, the 2001 debt securities and the guarantees will be governed by, and construed in accordance with, the laws of the State of New York. 15

Concerning the 2001 Debt Trustees Viacom will identify the 2001 debt trustees in the relevant prospectus supplement. In specific instances, Viacom or the holders of a majority of the then outstanding principal amount of the 2001 debt securities issued under a 2001 debt indenture may remove the 2001 debt trustee and appoint a successor trustee. The 2001 debt trustee may become the owner or pledgee of any of the 2001 debt securities with the same rights, subject to conflict of interest restrictions, it would have if it were not the 2001 debt trustee. The 2001 debt trustee and any successor trustee must be eligible to act as trustee under the 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 2001 debt 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 2001 debt trustee under each 2001 debt indenture is The Bank of New York. 2001 Senior Debt Securities Viacom will describe the specific terms of the 2001 senior 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 2001 senior debt securities in the prospectus supplement relating to that series. 2001 Senior Subordinated Debt Securities In addition to the provisions previously described in this prospectus and applicable to all 2001 debt securities, the following description of Viacom's 2001 senior subordinated debt securities summarizes the additional terms and provisions of its 2001 senior subordinated debt securities to which any prospectus supplement may relate. The specific terms of Viacom's 2001 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 2001 senior subordinated debt securities will be described in the prospectus supplement relating to that series. Subordination. The 2001 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 the 2001 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 of, premium, if any, or interest on the 2001 senior subordinated debt securities and may not acquire, or make payment on account of any sinking fund for, the 2001 senior subordinated debt securities unless full payment of amounts then due for principal, premium, if any, and interest on all senior indebtedness by reason of the maturity thereof has been made or duly provided for in cash or in a manner satisfactory to the holders of the senior indebtedness. In addition, the senior subordinated indenture provides that if a default has occurred giving the holders of the senior indebtedness the right to accelerate the maturity of that senior indebtedness, or an event has occurred which, with the giving of notice, or lapse of time, or both, would constitute an event of default, then unless and until that event has been cured or waived or has ceased to exist, no payment of principal, premium, if any, or interest on the 2001 senior subordinated debt securities and no acquisition of, or payment on account of a sinking fund for, the 2001 senior subordinated debt securities may be made. Viacom will give prompt written notice to the 2001 senior subordinated trustee of any default under any senior indebtedness or under any agreement pursuant to which senior indebtedness may have been issued. The 2001 senior subordinated indenture provisions described in this paragraph, however, do 16

not prevent Viacom from making a sinking fund payment with 2001 senior subordinated debt securities acquired prior to the maturity of senior indebtedness or, in the case of default, prior to the default and notice thereof. Upon any distribution of assets in connection with Viacom's dissolution, liquidation or reorganization, all senior indebtedness must be paid in full before the holders of the 2001 senior subordinated debt securities are entitled to any payments whatsoever. As a result of these subordination provisions, in the event of Viacom's insolvency, holders of the 2001 senior subordinated debt securities may recover ratably less than the holders of Viacom's senior indebtedness. For purposes of the description of the 2001 senior subordinated debt securities, the term "Senior Indebtedness" of the Company or the Guarantor, as the case may be, means the principal of and premium, if any, and interest on the following, whether outstanding on the date of execution of the senior subordinated indenture or incurred or created after the execution: o indebtedness for money borrowed by it, or evidenced by securities, other than the 2001 senior subordinated debt securities or any other indebtedness which is subordinate to the 2001 senior subordinated debt securities o obligations with respect to letters of credit; o indebtedness constituting a guarantee of indebtedness of others, other than any subordinated guarantees; or o obligations under Capitalized Leases (as defined below) (other than (x) telecommunications equipment, including satellite transponders, and (y) theme park equipment and attractions); o any obligation of a third party if secured by a lien on assets; o renewals, extensions or refundings of any of the indebtedness referred to in the preceding bullet points unless, in the case of any particular indebtedness, renewal, extension or refunding, under the express provisions of the instrument creating or evidencing the same, or pursuant to which the same is outstanding, the indebtedness or the renewal, extension or refunding thereof is not superior in right of payment to the 2001 senior subordinated debt securities. Senior Indebtedness of the Company or the Guarantor, as the case may be, will not include any obligation of the Company or the Guarantor (i) to any subsidiary of the Company or the Guarantor or to any person with respect to which the Company or the Guarantor is a subsidiary or (ii) specifically with respect to the production, distribution or acquisition of motion pictures or other programming rights, talent or publishing rights. As of March 31, 2001, a total of approximately $10.2 billion of Viacom's indebtedness was Senior Indebtedness and approximately $647 million of Viacom International's indebtedness was Senior Indebtedness. Certain Definitions The following definitions are applicable to the 2001 debt indentures: "Capitalized Lease" means any obligation of a person to pay rent or other amounts incurred with respect to real property or equipment 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. "Indebtedness" of any person means, without duplication (i) any obligation of such person for money borrowed, (ii) any obligation of such person evidenced by bonds, debentures, notes or other similar instruments, (iii) any reimbursement obligation of such person in respect of letters of credit or 17

other similar instruments which support financial obligations which would otherwise become Indebtedness, (iv) any obligation of such person under Capitalized Leases (other than in respect of (x) telecommunications equipment including, without limitation, satellite transponders, and (y) theme park equipment and attractions), and (v) any obligation of any third party to the extent secured by a Lien on the assets of such person; provided, however, that "Indebtedness" of such person shall not include any obligation of such person (i) to any Subsidiary of such person or to any person with respect to which such person is a Subsidiary or (ii) specifically with respect to the production, distribution or acquisition of motion pictures or other programming rights, talent or publishing rights. When used with respect to Viacom, the term "Indebtedness" also includes any obligation of Viacom International specified in clauses (i) through (v) above to the extent that said Indebtedness is guaranteed by Viacom. "Lien" means any pledge, mortgage, lien, encumbrance or other security interest. "Restricted Subsidiary" means a corporation all of the outstanding voting stock of which is owned, directly or indirectly, by Viacom or by one or more of its Subsidiaries, or by Viacom and one or more of its Subsidiaries, which is incorporated under the laws of a State of the United States, and which owns a Principal Property. "Subsidiary" of any person means (i) a corporation a majority of the outstanding voting stock of which is at the time, directly or indirectly, owned by such person, by one or more Subsidiaries of such person, or by such person and one or more Subsidiaries thereof or (ii) any other person (other than a corporation), including, without limitation, a partnership or joint venture, in which such person, one or more Subsidiaries thereof, or such person and one or more Subsidiaries thereof, directly or indirectly, at the date of determination thereof, has at least majority ownership interest entitled to vote in the election of directors, managers or trustees thereof (or other persons performing similar functions). 18

DESCRIPTION OF THE 1995 SENIOR DEBT SECURITIES Further Issues We may from time to time without notice to, or the consent of, the holders of a series of 1995 senior debt securities, create and issue further 1995 senior debt securities of the same series, equal in rank to the 1995 senior debt securities in all respects (or in all respects except for the payment of interest accruing prior to the issue date of the new notes or except for the first payment of interest following the issue date of the new notes) so that the new notes may be consolidated and form a single series with the relevant series of 1995 senior debt securities and have the same terms as to status, redemption or otherwise as the relevant series of 1995 senior debt securities. Merger, Consolidation or Sale of Assets Under the terms of the 1995 senior indenture, we and Viacom International generally would be permitted to consolidate or merge with another corporation. We and Viacom International would also be permitted to sell all or substantially all of our assets to another person. However, neither we nor Viacom International may take any of these actions unless all the following conditions are met: o the merger, consolidation or sale of assets must not cause an Event of Default. See "-- Defaults and Remedies" below. An Event of Default for this purpose would also include any event that would be an Event of Default if the notice or time requirements were disregarded; o the person we would merge or consolidate with or sell all or substantially all of our assets to must be organized under the laws of any state of the United States; o the person we would merge or consolidate with or sell all or substantially all of our assets to must agree to be legally responsible for the outstanding securities issued under the 1995 senior indenture; and o we or Viacom International must deliver specified certificates and documents to the 1995 senior debt trustee. We and Viacom International may merge or consolidate with, or sell all or substantially all of our assets to each other or any of our Subsidiaries. When we make reference in this section to the sale of "all or substantially all of our assets," we mean property and assets generating revenues representing, in the aggregate, at least 80% of our total consolidated revenues. In the event that Viacom or Viacom International 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 or Viacom International, as the case may be, under the 1995 senior indenture and Viacom or Viacom International, as the case may be, shall be discharged from all of its obligations under the 1995 senior indenture. Limitations on Liens We covenant in the 1995 senior indenture that we will not create, assume or permit any Lien on any of our properties or assets, unless we secure the 1995 senior 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 19

leaseback arrangement. See "-- Limitations on Sale and Leaseback Transactions" below. The restrictions do not apply to Capitalized Leases or Indebtedness that is secured by: o Liens existing, in the case of any 1995 senior debt securities, on the date such 1995 senior debt securities are issued; o 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); o Liens in favor of us or our Subsidiaries; and o 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 1995 senior 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 1995 senior debt securities are issued or that exist at the time any person that owns a Principal Property becomes a Restricted Subsidiary) which has been or is to be sold by us or the Restricted Subsidiary to the person unless: o the sale and leaseback arrangement involves a lease for a term of not more than three years; o the sale and leaseback arrangement is entered into between us and any Subsidiary or between our Subsidiaries; o 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 1995 senior debt securities; o 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 1995 senior debt securities and that is not debt to us or a Subsidiary, or (ii) the purchase or development of other comparable property; or o 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 1995 senior 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 20

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 1995 senior indenture. The term "Principal Property" is defined in the 1995 senior 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 $1.0 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 1995 senior debt securities have specified rights if an Event of Default occurs in respect of the 1995 senior debt securities of that series, as described below. The term "Event of Default" in respect of the 1995 senior debt securities means any of the following: o we do not pay interest on a 1995 senior debt security of such series within 30 days of its due date; o we do not pay the principal of or any premium on a 1995 senior debt security of such series on its due date; o we remain in breach of a covenant or warranty in respect of the 1995 senior indenture for 60 days after we receive a written notice of default. The notice must be sent by either the trustee or holders of at least 25% in principal amount of a series of outstanding 1995 senior debt securities; o we are in default under agreements under which we have Indebtedness outstanding in excess of $250 million in the aggregate and which Indebtedness is due either at maturity or has been declared due prior to maturity and remains unpaid; o we fail to pay a money judgment in excess of $250 million for a period of 60 days after it becomes final and not subject to further appeal; or o we or Viacom International file for bankruptcy, or other specified events of bankruptcy, insolvency or reorganization occur. If an Event of Default has occurred, the 1995 senior debt trustee or the holders of at least 25% in principal amount of the 1995 senior debt securities of the affected series may declare the entire principal amount and premium, if any, and all the accrued interest on, the 1995 senior 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 1995 senior debt trustee or any holder of 1995 senior 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 1995 senior debt securities of a series may also waive certain past defaults under the 1995 senior indenture on behalf of all of the holders of such series of 1995 senior debt securities. A declaration of acceleration of maturity may be canceled, under specified 21

circumstances, by the holders of at least a majority in principal amount of a series of 1995 senior debt securities. Except in cases of default, where the 1995 senior debt trustee has special duties, the 1995 senior debt trustee is not required to take any action under the 1995 senior indenture at the request of holders unless the holders offer the 1995 senior debt trustee reasonable protection from expenses and liability satisfactory to the 1995 senior debt trustee. If a reasonable indemnity is provided, the holders of a majority in principal amount of a series of 1995 senior debt securities may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the 1995 senior debt trustee. The 1995 senior debt trustee may refuse to follow those directions in specified circumstances. 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 1995 senior debt 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 1995 senior debt securities, the following must occur: o holders must give the 1995 senior debt trustee written notice that an Event of Default has occurred and remains uncured; o holders of at least 25% in principal amount of the outstanding 1995 senior debt securities of a series must make a written request that the 1995 senior debt trustee take action because of the default and must offer the 1995 senior debt trustee indemnity satisfactory to the 1995 senior debt trustee against the cost and other liabilities of taking that action; o the 1995 senior debt trustee must have failed to take action for 60 days after receipt of the notice and offer of indemnity; and o holders of a majority in principal amount of the 1995 senior debt securities of a series must not have given the 1995 senior debt trustee a direction inconsistent with the above notice. Holders of 1995 senior debt securities are, however, entitled at any time to bring a lawsuit for the payment of money due on those 1995 senior debt securities on or after the due date. We are required to furnish to the 1995 senior debt trustee an annual statement as to our performance of our obligations under the 1995 senior indenture and as to any default in such performance. We are also required to notify the 1995 senior debt trustee of any event that is, or after notice or lapse of time or both would become, an Event of Default. Payment and Paying Agents Unless otherwise specified in the applicable prospectus supplement, principal of, premium, if any, and interest on the 1995 senior debt securities will be payable, subject to any applicable laws and regulations, at the office of our paying agent or paying agents that we may designate from time to time, except that at our option, payment of interest may be made by check mailed to the address of the person entitled thereto at the address in the security register. Unless otherwise specified in the applicable prospectus supplement, we will pay interest on the 1995 senior debt securities on any interest payment date to the person in whose name the 1995 senior debt security (or predecessor 1995 senior debt security) is registered at the close of business on the regular record date for such interest. 22

Unless otherwise specified in the applicable prospectus supplement, the corporate trust office of the 1995 senior debt trustee will be designated as our paying agent for payments with respect to the 1995 senior debt securities of each series. We may at any time designate additional paying agents or rescind the designation of any paying agent or approve a change in the office through which any paying agent acts, except that we will be required to maintain a paying agent in each place of payment for the series. Any money paid by us or Viacom International, as guarantor, to a paying agent for the payment of the principal of, premium, if any, or interest on any 1995 senior debt security of any series that remains unclaimed at the end of two years after such principal, premium or interest has become due and payable will be repaid to us or Viacom International, as guarantor, as the case may be, and the holder of such 1995 senior debt security may thereafter look only to us and Viacom International for that payment. Meetings, Modification and Waiver The 1995 senior debt indenture provides that Viacom, Viacom International, if applicable, and the 1995 senior debt trustee may, without the consent of any holders of 1995 senior debt securities, enter into supplemental indentures for the purposes, among other things, of: o adding to Viacom or Viacom International's covenants; o adding additional events of default; o change or eliminate any provisions of the 1995 debt indenture so long as there are no holders entitled to the benefit of the provisions; o establishing the form or terms of any series of debt securities; or o curing ambiguities or inconsistencies in the debt indenture or making other provisions. Modifications and amendments of the 1995 senior indenture may be made by us, Viacom International, as guarantor, and the 1995 senior debt trustee with the consent of the holders of not less than a majority in aggregate principal amount of the outstanding 1995 senior debt securities of each series affected by such modification or amendment; provided, however, that no such modification or amendment may, without the consent of the holders of each outstanding 1995 senior debt security affected thereby, (a) change the stated maturity of the principal of, or any installment of principal of or interest on, any 1995 senior debt security or the terms of any sinking fund or analogous payment with respect to any 1995 senior debt security, (b) reduce the principal amount of, or premium or interest on, any 1995 senior debt security, (c) change our obligation to pay additional amounts, (d) reduce the amount of principal of an original issue discount 1995 senior debt security payable upon acceleration of the maturity thereof or provable in bankruptcy, (e) change the place of payment where, or the coin or currency in which, any 1995 senior debt security or any premium or interest thereon is payable, (f) impair the right to institute suit for the enforcement of any payment on or with respect to any 1995 senior debt security, (g) reduce the percentage in principal amount of outstanding 1995 senior debt securities of any series, the consent of whose holders is required for modification or amendment of the 1995 senior indenture or for waiver of compliance with certain provisions of the 1995 senior indenture or for waiver of certain defaults, (h) reduce the requirements contained in the 1995 senior indenture for quorum or voting, (i) change our obligation to maintain an office or agency in the places and for the purposes required by the 1995 senior indenture, or (j) reduce the obligations of Viacom International, if any, in respect of the due and punctual payment of any principal of, premium or interest on any 1995 senior debt security or any additional amounts in respect thereof. 23

The holders of at least a majority in aggregate principal amount of the outstanding 1995 senior debt securities of a series may, on behalf of the holders of all the 1995 senior debt securities of that series, waive, insofar as that series is concerned, our compliance with specified provisions of the 1995 senior indenture. The holders of not less than a majority in aggregate principal amount of the outstanding 1995 senior debt securities of a series may, on behalf of all holders of 1995 senior debt securities of that series, waive any past default under the 1995 senior indenture with respect to 1995 senior debt securities of that series, except a default (a) in the payment of principal of or any premium or interest on any 1995 senior debt security of such series or (b) in respect of any other provision of the 1995 senior indenture that cannot be modified or amended without the consent of the holder of each outstanding 1995 senior debt security of such series affected thereby. The 1995 senior indenture provides that, in determining whether the holders of the requisite principal amount of the outstanding 1995 senior debt securities have given any request, demand, authorization, direction, notice, consent or waiver thereunder or are present at a meeting of holders of 1995 senior debt securities for quorum purposes, the principal amount of an original issue discount senior security that shall be deemed to be outstanding shall be the amount that would be due and payable as of the date of such determination upon acceleration of the maturity thereof. The 1995 senior indenture contains provisions for convening meetings of the holders of 1995 senior debt securities of any or all series. A meeting may be called at any time by the 1995 senior debt trustee, and also, upon request, by us or the holders of at least 33 1/3% in aggregate principal amount of the outstanding 1995 senior debt securities of such series, in any such case upon notice given in accordance with "Notices" below. Except for any consent that must be given by the holder of each outstanding 1995 senior debt security affected thereby, as described above, any resolution presented at a meeting or adjourned meeting at which a quorum is present may be adopted by the affirmative vote of the holders of a majority in principal amount of the outstanding 1995 senior debt securities of that series; provided, however, that, except for any consent that must be given by the holder of each outstanding 1995 senior debt security affected thereby, as described above, any resolution with respect to any consent, waiver, request, demand, notice, authorization, direction or other action that may be made, given or taken by the holders of not less than a specified percentage in principal amount of the outstanding 1995 senior debt securities of a series may be adopted at a meeting or an adjourned meeting at which a quorum is present only by the affirmative vote of the holders of not less than such specified percentage in principal amount of the outstanding 1995 senior debt securities of that series. Any resolution passed or decision taken at any meeting of holders of 1995 senior debt securities of any series duly held in accordance with the 1995 senior indenture will be binding on all holders of 1995 senior debt securities of that series. The quorum at any meeting called to adopt a resolution, and at any adjourned meeting, will be persons holding or representing a majority in principal amount of the outstanding 1995 senior debt securities of a series; provided, however, that, if any action is to be taken at such meeting with respect to a consent, waiver, request, demand, notice, authorization, direction or other action that may be given by the holders of not less than a specified percentage in principal amount of the outstanding 1995 senior debt securities of a series, the persons holding or representing such specified percentage in principal amount of the outstanding 1995 senior debt securities of such series will constitute a quorum. Defeasance and Covenant Defeasance We may elect either (i) to defease and be discharged (and, if applicable, to have Viacom International defeased and discharged) from any and all obligations with respect to the 1995 senior debt securities (except as otherwise provided in the 1995 senior indenture) ("defeasance") or (ii) to be released from our obligations with respect to certain covenants that are described in the 1995 senior indenture 24

("covenant defeasance"), upon the deposit with the 1995 senior debt trustee, in trust for such purpose, of money and/or specified 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 1995 senior 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, we must deliver to the 1995 senior debt trustee an opinion of counsel to the effect that the holders of the 1995 senior 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 1995 senior indenture. We may exercise our defeasance option with respect to the 1995 senior debt securities of any series notwithstanding the prior exercise of our covenant defeasance option. If we exercise our defeasance option, payment of the 1995 senior debt securities of such series may not be accelerated because of an event of default and the guarantees relating to such 1995 senior debt securities will cease to exist. If we exercise our covenant defeasance option, payment of the 1995 senior debt securities of such series may not be accelerated by reference to any covenant from which we are released as described under clause (ii) above. 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 1995 senior 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 1995 senior debt securities will be given by mail to the addresses of such holders as they appear in the security register. Title We, Viacom International, as guarantor, the 1995 senior debt trustee and any agent of us, may treat the registered owner of any registered 1995 senior debt security as the absolute owner thereof (whether or not the 1995 senior 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 1995 Senior Debt Securities We will replace any mutilated 1995 senior debt security at the expense of the holders upon surrender to the trustee. We will replace 1995 senior 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 1995 senior debt security, an indemnity or security satisfactory to us and the 1995 senior debt trustee may be required at the expense of the holder of the 1995 senior debt security before a replacement 1995 senior debt security will be issued. Governing Law The 1995 senior indenture, the 1995 senior debt securities and the guarantees will be governed by, and construed in accordance with, the laws of the State of New York. 25

Regarding the 1995 Senior Debt Trustee We and Viacom International maintain deposit accounts and banking and borrowing relations with Citibank, N.A., the 1995 senior debt trustee under the 1995 senior indenture, and such 1995 senior debt trustee is currently a lender to us and Viacom International and certain of our other subsidiaries. We may remove the 1995 senior debt trustee at any time with respect to the 1995 senior debt securities of any series, provided that we immediately appoint a successor trustee meeting the requirements for trustees specified in the 1995 senior indenture and provided further that no default with respect to such 1995 senior debt securities has occurred and is continuing. Certain Definitions The following definitions are applicable to the 1995 senior indenture: "Capitalized Lease" means any obligation of a person to pay rent or other amounts incurred with respect to real property or equipment 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. "Indebtedness" of any person means, without duplication (i) any obligation of such person for money borrowed, (ii) any obligation of such person evidenced by bonds, debentures, notes or other similar instruments, (iii) any reimbursement obligation of such person in respect of letters of credit or other similar instruments which support financial obligations which would otherwise become Indebtedness, (iv) any obligation of such person under Capitalized Leases (other than in respect of (x) telecommunications equipment including, without limitation, satellite transponders, and (y) theme park equipment and attractions), and (v) any obligation of any third party to the extent secured by a Lien on the assets of such person; provided, however, that "Indebtedness" of such person shall not include any obligation of such person (a) to any Subsidiary of such person or to any person with respect to which such person is a Subsidiary or (b) specifically with respect to the production, distribution or acquisition of motion pictures or other programming rights, talent or publishing rights. When used with respect to Viacom, the term "Indebtedness" also includes any obligation of Viacom International specified in clauses (i) through (v) above to the extent that said Indebtedness is guaranteed by Viacom. "Lien" means any pledge, mortgage, lien, encumbrance or other security interest. "Restricted Subsidiary" means a corporation all of the outstanding voting stock of which is owned, directly or indirectly, by Viacom or by one or more of its Subsidiaries, or by Viacom and one or more of its Subsidiaries, which is incorporated under the laws of a State of the United States, and which owns a Principal Property. "Subsidiary" of any person means (i) a corporation a majority of the outstanding voting stock of which is at the time, directly or indirectly, owned by such person, by one or more Subsidiaries of such person, or by such person and one or more Subsidiaries thereof or (ii) any other person (other than a corporation), including, without limitation, a partnership or joint venture, in which such person, one or more Subsidiaries thereof, or such person and one or more Subsidiaries thereof, directly or indirectly, at the date of determination thereof, has at least majority ownership interest entitled to vote in the election of directors, managers or trustees thereof (or other persons performing similar functions). 26

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 March 31, 2001, 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. 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: o in the case of cumulative preferred stock, all dividend periods terminating on or before the date of payment of full cumulative dividends; or o 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 28

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, and 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. 29

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. Preferred Stock Guarantees The following description summarizes the general terms and provisions of the preferred stock guarantees that may be executed and delivered by Viacom International for the benefit of the holders from time to time of our preferred stock. The terms and provisions of each preferred stock guarantee will be as set forth in each preferred stock guarantee. This description is qualified in its entirety by reference to the form of preferred stock guarantee agreement, which is filed as an exhibit to the registration statement of which this prospectus forms a part. General Pursuant to each preferred stock guarantee, Viacom International will irrevocably and unconditionally agree to pay in full, to the holders of our preferred stock, certain payments, to the extent not paid by us, [regardless of any defense, right of set-off or counterclaim that we may have or assert]. Unless otherwise specified in the applicable prospectus supplement, the following payments or distributions with respect to our preferred stock will be subject to the preferred stock guarantee: o the redemption price, including all accrued and unpaid dividends to the date of redemption, with respect to any preferred stock called for redemption by Viacom; and o upon our voluntary or involuntary dissolution, winding-up or termination, the aggregate of the liquidation amount and all accrued and unpaid dividends on that preferred stock to the date of payment, to the extent that we have funds available. We will refer to these amounts as "guarantee payments" in this description. The obligation of Viacom International to make a guarantee payment may be satisfied by direct payment of the required amounts by Viacom International to the holders of preferred stock or by our payment of those amounts to those holders. In the event of a redemption or our voluntary or involuntary dissolution, winding-up or termination, the obligations of Viacom International under any issued preferred stock guarantees will in the aggregate provide a full and unconditional guarantee on a subordinated basis by Viacom International of payments due on the preferred stock, as further described below. Certain Covenants of Viacom International Unless otherwise specified in the applicable prospectus supplement, so long as any shares of preferred stock issued by us which are guaranteed by Viacom International are outstanding, Viacom International will not make any payment with respect to any capital stock issued by Viacom International, if at such time it is in default with respect to the guarantee payments or other payment obligations under the preferred stock guarantee. 30

Amendments and Assignment Except with respect to any changes that do not adversely affect the rights of holders of preferred stock, in which case no consent will be required, a preferred stock guarantee can be amended only with the prior approval of the holders of not less than 66 2/3% of the preferred stock. The manner of obtaining an approval of holders of the preferred stock will be described in an accompanying prospectus supplement. All guarantees and agreements contained in a preferred stock guarantee shall bind the successors, assignees, receivers, trustees and representatives of Viacom International and shall inure to the benefit of the holders of our preferred stock then outstanding. Except in connection with a consolidation, merger or sale involving Viacom that is permitted under the preferred stock guarantee agreement, Viacom International may not assign its obligations under any preferred stock guarantee. Termination of the Preferred Stock Guarantees Each preferred stock guarantee will terminate and be of no further force and effect as to any series of our preferred stock upon full payment of the redemption price of all shares of preferred stock of that series, or upon the full payment of amounts payable upon our liquidation. Notwithstanding the foregoing, each preferred stock guarantee will continue to be effective or will be reinstated, as the case may be, if at any time any holder of our preferred stock must restore payment of any sums paid under such preferred stock or such guarantee. Status of the Preferred Stock Guarantees The obligations of Viacom International under each preferred stock guarantee to make any guarantee payments will be an unsecured obligation of Viacom International and will rank: o subordinate and junior in right of payment to all of Viacom International's other liabilities, except those made pari passu or subordinate by their terms, o senior to all capital stock at any time issued by Viacom International and to any guarantee now or hereafter entered into by Viacom International in respect of any of its capital stock, and o proportionally and equally with each other preferred stock guarantee. Each preferred stock guarantee is a guarantee of payment and not of collection. A guaranteed party may institute a legal proceeding directly against the guarantor to enforce its rights under the guarantee without first instituting a legal proceeding against any other person or entity. Any holder of our preferred stock may institute a legal proceeding directly against Viacom International to enforce its rights under a preferred stock guarantee, without first instituting a legal proceeding against us or any other person or entity. Limitation of Guarantor's Liability Various federal and state fraudulent conveyance laws have been enacted for the protection of creditors and may be utilized by a court of competent jurisdiction to subordinate or avoid all or part of any guarantee issued by Viacom International. For a discussion of fraudulent conveyance laws, as applicable to upstream guarantees, such as the preferred stock guarantees, see "General Description of the Debt Securities -- Guarantees." 31

Governing Law The preferred stock guarantees will be governed by, and construed in accordance with, the laws of the State of New York.

Split, Subdivision or Combination. If Viacom splits, subdivides or combines 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 shall be proportionally split, subdivided or combined in the same manner and on the same basis as the outstanding shares of the other class of Viacom common stock have been split, subdivided or combined.

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, 2001 senior debt securities, 2001 senior subordinated debt securities or 1995 senior 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 2001 senior debt securities, 2001 senior subordinated debt securities, 1995 senior 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 2001 senior debt securities, 2001 senior subordinated debt securities, 1995 senior debt securities or shares of preferred stock purchasable upon the exercise.

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 2001 senior debt securities, 2001 senior subordinated debt securities, 1995 senior debt securities or shares of preferred stock purchasable upon the exercise, and, if applicable, Viacom International will issue guarantees relating to those securities.

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 35

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 either Viacom or Viacom International. 36

PART II INFORMATION NOT REQUIRED IN PROSPECTUS Item 14. Other Expenses of Issuance and Distribution. The following table sets forth the costs and expenses payable by Viacom in connection with the sale of the securities being registered hereby. All amounts are estimates except the registration fee. The costs and expenses set forth in the following table represent the sum of the costs and expenses of Registration Statement No. 333-52728 together with the incremental costs associated with this Registration Statement. Amounts to be Paid Registration fee.........................................$ 1,250,000 Legal fees and expenses.................................. 700,000 Blue Sky fees............................................ 50,000 Printing................................................. 500,000 Trustee fees............................................. 150,000 Rating agency fees....................................... 1,000,000 Accounting fees and expenses............................. 125,000 Miscellaneous............................................ 125,000 TOTAL....................................................$ 3,900,000 ============ Item 15. Indemnification of Directors and Officers. Section 145 of the Delaware General Corporation Law permits a corporation to indemnify any of its directors or officers who is or was a party, or is threatened to be made a party, to any third party proceeding by reason of the fact that such person is or was a director or officer of the corporation, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reason to believe that such person's conduct was unlawful. In a derivative action, i.e., one by or in the right of a corporation, the corporation is permitted to indemnify directors and officers against expenses (including attorneys' fees) actually and reasonably incurred by them in connection with the defense or settlement of an action or suit if they acted in good faith and in a manner that they reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification shall be made if such person shall have been adjudged liable to the corporation, unless and only to the extent that the court in which the action or suit was brought shall determine upon application that the defendant directors or officers are fairly and reasonably entitled to indemnity for such expenses despite such adjudication of liability. Expenses, including attorneys' fees, incurred by any such person in defending any such action, suit or proceeding may be paid or reimbursed by the corporation in advance of the final disposition of such action, suit or proceeding upon receipt by it of an undertaking of such person to repay such expenses if it shall ultimately be determined that such person is not entitled to be indemnified by the corporation. Delaware law does not permit a corporation to indemnify persons against judgments in actions brought by or in the right of the corporation unless the Delaware Court of Chancery approves the indemnification. II-1

Viacom's restated certificate of incorporation provides that each person who was or is a party, or is threatened to be made a party, to any threatened, pending or completed action or proceeding, whether civil, criminal, administrative or investigative, because that person is or was a Viacom director or officer or is or was serving at Viacom's request as a director or officer of another entity, shall be indemnified and held harmless by Viacom to the fullest extent permitted by Delaware law. This right to indemnification also includes the right to be paid by Viacom the expenses incurred in connection with that proceeding in advance of its final disposition to the fullest extent authorized by Delaware law. This right to indemnification is a contract right. Viacom's restated certificate of incorporation authorizes its board of directors to indemnify any of Viacom's employees or agents to the extent approved by the board of directors and authorized under Delaware law. Viacom intends to purchase and maintain insurance on behalf of any person who is or was one of its directors, officers, employees or agents, or is or was serving at the request of Viacom as a director, officer, employee or agent of another entity against any liability asserted against him or her and incurred by him or her in that capacity, or arising out of his or her status as such, whether or not Viacom would have the power or the obligation to indemnify him or her against that liability under the provisions of Viacom's restated certificate of incorporation.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (b) The undersigned registrants hereby understand that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrants pursuant to the foregoing provisions, or otherwise, the registrants have been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrants will, unless in the opinion of their counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.
