The Clearing Systems

DTC.    The depositary has advised us as follows: the depositary is a limited-purpose trust company organized under the New York Banking Law, a ‘‘banking organization’’ within the meaning of the New York Banking Law, a member of the Federal Reserve System, a ‘‘clearing corporation’’ within the meaning of the New York Uniform Commercial Code, and a ‘‘clearing agency’’ registered pursuant to the provisions of Section 17A of the Exchange Act. The depositary holds securities deposited with it by its participants and facilitates the settlement of transactions among its participants in such securities through electronic computerized book-entry changes in accounts of the participants, thereby eliminating the need for physical movement of securities certificates. The depositary’s participants include securities brokers and dealers (including the underwriters), banks, trust companies, clearing corporations and certain other organizations, some of whom (and/or their representatives) own the depositary. Access to the depositary’s book-entry system is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly.

According to the depositary, the foregoing information with respect to the depositary has been provided to the financial community for informational purposes only and is not intended to serve as a representation, warranty or contract modification of any kind.

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

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

Euroclear.    Euroclear has advised that it was created in 1968 to hold securities for its participants and to clear and settle transactions between Euroclear participants through simultaneous electronic book-entry delivery against payment, eliminating the need for physical movement of certificates and eliminating any risk from lack of simultaneous transfers of securities and cash. Euroclear provides various other services, including securities lending and borrowing and interfaces with domestic markets in several countries. The Euroclear System is owned by Euroclear Clearance System Public Limited Company (ECSplc) and operated through a license agreement by Euroclear Bank S.A./N.V., a bank incorporated under the laws of the Kingdom of Belgium as the ‘‘Euroclear operator.’’

The Euroclear operator holds securities and book-entry interests in securities for participating organizations and facilitates the clearance and settlement of securities transactions between Euroclear participants, and between Euroclear participants and participants of certain other securities intermediaries through electronic book-entry changes in accounts of such participants or other securities intermediaries.

The Euroclear operator provides Euroclear participants, among other things, with safekeeping, administration, clearance and settlement, securities lending and borrowing, and related services.  

Non-participants of Euroclear may hold and transfer book-entry interests in the securities through accounts with a direct participant of Euroclear or any other securities intermediary that holds a

S-11

Table of Contents

book-entry interest in the securities through one or more securities intermediaries standing between such other securities intermediary and the Euroclear operator.

The Euroclear operator is regulated and examined by the Belgian Banking and Finance Commission and the National Bank of Belgium.

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

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

Global Clearance and Settlement Procedures

Initial settlement for the senior notes will be made in same-day U.S. dollar funds.

Secondary market trading between DTC participants will occur in the ordinary way in accordance with DTC rules. Secondary market trading between Clearstream Luxembourg participants and/or Euroclear participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream Luxembourg and Euroclear and will be settled using the procedures applicable to conventional eurobonds.

Cross-market transfers between persons holding directly or indirectly through DTC participants, on the one hand, and directly or indirectly through Clearstream Luxembourg or Euroclear participants, on the other hand, will be effected in DTC in accordance with DTC rules on behalf of the relevant international clearing system by its U.S. depositary. However, cross-market transactions will require delivery of instructions to the relevant international clearing system by the counterparty in that system in accordance with its rules and procedures and within its established deadlines (European time). The relevant international clearing system will, if a transaction meets its settlement requirements, deliver instructions to its U.S. depositary to take action to effect final settlement on its behalf by delivering or receiving securities in DTC. Clearstream Luxembourg participants and Euroclear participants may not deliver instructions directly to the respective U.S. depositary.

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

Although it is expected that DTC, Clearstream Luxembourg and Euroclear will follow the foregoing procedures in order to facilitate transfers of notes among participants of DTC, Clearstream Luxembourg and Euroclear, they are under no obligation to perform or continue such procedures and such procedures may be changed or discontinued at any time.

Payment of Additional Amounts

We will, subject to the exceptions and limitations set forth below, pay as additional interest on our senior notes such additional amounts as are necessary so that the net payment by us or a paying

agent of the principal of and interest on our senior notes to a person that is a non-U.S. holder (as defined under the heading ‘‘United States Federal Income Taxation’’ below), after deduction for any present or future tax, assessment or governmental charge of the United States or a political subdivision or taxing authority thereof or therein, imposed by withholding with respect to the payment, will not be less than the amount that would have been payable in respect of our senior notes had no withholding or deduction been required.

Our obligation to pay additional amounts shall not apply:

	(1)	to any tax, assessment or governmental charge that is imposed or withheld solely because the beneficial owner, or a fiduciary, settlor, beneficiary or member of the beneficial owner if the beneficial owner is an estate, trust or partnership, or a person holding a power over an estate or trust administered by a fiduciary holder:

	(a)	is or was present or engaged in trade or business in the United States or has or had a permanent establishment in the United States;

	(b)	is or was a citizen or resident or is or was treated as a resident of the United States;

	(c)	is or was a foreign or domestic personal holding company, a passive foreign investment company or a controlled foreign corporation with respect to the United States or is or was a corporation that has accumulated earnings to avoid United States federal income tax; or

	(d)	is or was a ‘‘10-percent shareholder’’ of CBS Corp.;

	(2)	to any holder that is not the sole beneficial owner of our senior notes, or a portion thereof, or that is a fiduciary or partnership, but only to the extent that the beneficial owner, a beneficiary or settlor with respect to the fiduciary, or a member of the partnership would not have been entitled to the payment of an additional amount had such beneficial owner, beneficiary, settlor or member received directly its beneficial or distributive share of the payment;

	(3)	to any tax, assessment or governmental charge that is imposed or withheld solely because the beneficial owner or any other person failed to comply with certification, identification or information reporting requirements concerning the nationality, residence, identity or connection with the United States of the holder or beneficial owner of our senior notes, if compliance is required by statute, by regulation of the United States Treasury Department or by an applicable income tax treaty to which the United States is a party as a precondition to exemption from such tax, assessment or other governmental charge;

	(4)	to any tax, assessment or governmental charge that is imposed other than by deduction or withholding by CBS Corp. or a paying agent from the payment;

	(5)	to any tax, assessment or governmental charge that is imposed or withheld solely because of a change in law, regulation, or administrative or judicial interpretation that becomes effective after the day on which the payment becomes due or is duly provided for, whichever occurs later;

	(6)	to an estate, inheritance, gift, sales, excise, transfer, wealth or personal property tax or any similar tax, assessment or governmental charge;

	(7)	to any tax, assessment or other governmental charge any paying agent (which term may include us) must withhold from any payment of principal of or interest on any senior note, if such payment can be made without such withholding by any other paying agent; or

	(8)	in the case of any combination of the above items.

Our senior notes are subject in all cases to any tax, fiscal or other law or regulation or administrative or judicial interpretation applicable. Except as specifically provided under this heading ‘‘—Payment of Additional Amounts’’ and under the heading ‘‘—Redemption Upon a Tax Event,’’ we do not have to make any payment with respect to any tax, assessment or governmental charge imposed by any government or a political subdivision or taxing authority.

Table of Contents

In particular, we will not pay additional amounts on any senior note

	•	where withholding or deduction is imposed on a payment to an individual and is required to be made pursuant to European Union Council Directive 2003/48/EC of June 3, 2003 on the taxation of savings income in the form of interest payments, or any law implementing or complying with, or introduced in order to conform to, that Directive; or

	•	presented for payment by or on behalf of a beneficial owner who would have been able to avoid the withholding or deduction by presenting the relevant global note to another paying agent in a member state of the European Union.

Redemption Upon a Tax Event

If (a) we become or will become obligated to pay additional amounts as described herein under the heading ‘‘—Payment of Additional Amounts’’ as a result of any change in, or amendment to, the laws (or any regulations or rulings promulgated thereunder) of the United States (or any political subdivision or taxing authority thereof or therein), or any change in, or amendments to, any official position regarding the application or interpretation of such laws, regulations or rulings, which change or amendment is announced or becomes effective on or after the date of this prospectus supplement, or (b) a taxing authority of the United States takes an action on or after the date of this prospectus supplement, whether or not with respect to us or any of our affiliates, that results in a substantial probability that we will or may be required to pay such additional amounts, then we may, at our option, redeem, as a whole, but not in part, our senior notes on any interest payment date on not less than 30 nor more than 60 calendar days’ prior notice, at a redemption price equal to 100% of their principal amount, together with interest accrued thereon to the date fixed for redemption. However, we may determine, in our business judgment, that the obligation to pay these additional amounts cannot be avoided by the use of reasonable measures available to us, not including substitution of the obligor under our senior notes. No redemption pursuant to (b) above may be made unless we shall have received an opinion of independent counsel to the effect that an act taken by a taxing authority of the United States results in a substantial probability that we will or may be required to pay the additional amounts described herein under the heading ‘‘—Payment of Additional Amounts’’ and we shall have delivered to the trustee a certificate, signed by a duly authorized officer, stating that based on such opinion we are entitled to redeem our senior notes pursuant to their terms.

Table of Contents

UNITED STATES FEDERAL INCOME TAXATION

This summary describes the material U.S. federal income tax consequences of the purchase, ownership and disposition of senior notes, subject to the limitations stated below. This summary is based on the Internal Revenue Code of 1986, as amended (the ‘‘Code’’), Treasury Regulations (including proposed Regulations and temporary Regulations) promulgated thereunder, rulings, official pronouncements and judicial decisions, all as in effect on the date of this prospectus supplement and all of which are subject to change, possibly with retroactive effect, or to different interpretations. This summary provides general information only and does not address all of the U.S. federal income tax consequences that may be applicable to a holder of senior notes. It does not address all of the tax consequences that may be relevant to certain types of holders subject to special treatment under the U.S. federal income tax law, such as individual retirement and other tax-deferred accounts, dealers in securities or currencies, financial institutions, life insurance companies, tax-exempt organizations, persons holding senior notes as a hedge, as a position in a straddle for tax purposes, or as part of a ‘‘synthetic security’’ or other integrated investment comprised of senior notes and one or more other investments, U.S. holders (as defined below) whose functional currency is other than the U.S. dollar, or certain U.S. expatriates. This summary is limited to initial purchasers who hold senior notes as a capital asset within the meaning of Section 1221 of the Code. Persons considering the purchase of senior notes should consult their own tax advisors concerning the application of the U.S. federal income tax law to their particular situations, as well as any tax consequences arising under the law of any state, local or foreign tax jurisdiction.

For purposes of the following discussion, the term ‘‘U.S. holder’’ means a beneficial owner of senior notes who is an individual who is a citizen or resident of the United States, an estate subject to U.S. federal income taxation without regard to the source of its income, a corporation or other business entity treated as a corporation for U.S. federal income tax purposes created or organized in or under the laws of the United States, any state thereof or the District of Columbia, or a trust if a valid election to be treated as a U.S. person, as defined in the Code, is in effect with respect to such trust or both: (x) a court within the United States is able to exercise primary supervision over the administration of the trust, and (y) one or more U.S. persons have the authority to control all substantial decisions of the trust. The term ‘‘non-U.S. holder’’ means a beneficial owner of senior notes who is an individual, estate, corporation or trust that is not a U.S. holder.

If a partnership (including for this purpose any entity treated as a partnership for U.S. federal income tax purposes) is a beneficial owner of senior notes, the treatment of a partner in the partnership will generally depend upon the status of the partner and upon the activities of the partnership. A holder of senior notes that is a partnership and partners in such partnership should consult their tax advisors.

Treatment of Senior Notes

We believe that the senior notes constitute indebtedness for U.S. federal income tax purposes, and the following discussion assumes such treatment. No ruling has been or will be obtained from the Internal Revenue Service (the ‘‘IRS’’) regarding the U.S. federal income tax treatment of the senior notes, and no assurances can be given that the IRS will not take a contrary position.

U.S. Holders

Payments of Interest on Senior Notes

Payment of interest on senior notes will be taxable to a U.S. holder as ordinary interest income at the time it is accrued or received in accordance with the U.S. holder’s method of tax accounting.

Sale, Exchange or Retirement of Senior Notes

Upon the sale, exchange or retirement of senior notes, a U.S. holder generally will recognize gain or loss equal to the difference between the amount realized on the sale, exchange or retirement,

S-15

---

Table of Contents

except to the extent such amount is attributable to accrued but unpaid interest, and the holder’s tax basis in the senior notes. Gain or loss so recognized will be capital gain or loss and will be long-term capital gain or loss, if, at the time of the sale, exchange or retirement, the senior notes were held for more than one year. Under current law, long-term capital gains of non-corporate taxpayers are, under certain circumstances, taxed at lower rates than items of ordinary income. The deductibility of capital losses is subject to limitations.

Non-U.S. Holders

Subject to the discussion of backup withholding below, payments of interest by us or our agent (in its capacity as such) to any non-U.S. holder will generally not be subject to U.S. federal withholding tax, provided that:

	(1)	such holder does not actually or constructively own 10% or more of the total combined voting power of all classes of our stock entitled to vote;

	(2)	such holder is not a controlled foreign corporation for U.S. federal income tax purposes that is related to us through stock ownership;

	(3)	such holder is not a bank receiving interest described in Code Section 881(c)(3)(A); and

	(4)	neither we nor our agent has actual knowledge or reason to know that such holder is a U.S. person, and either

	(a)	such holder properly certifies to us or our agent, under penalties of perjury, that such holder is not a U.S. person and provides its name and address (which certification can be made on IRS Form W-8BEN or a suitable substitute); or

	(b)	a securities clearing organization, bank or other financial institution that holds customers’ securities in the ordinary course of its trade or business (a ‘‘financial institution’’) properly certifies to us or our agent, under penalties of perjury (which certification can be made on IRS Form W-8IMY or a suitable substitute), that the certification described in clause (4)(a) above has been received from the beneficial owner by it or by another financial institution acting for the beneficial owner and delivers to us or our agent a copy of the certification described in clause (4)(a) above.

Alternatively, these certification requirements will not apply if the non-U.S. holder holds the senior notes through a ‘‘qualified intermediary’’ (which is a non-U.S. office of a bank, securities dealer or similar intermediary that has signed an agreement with the IRS concerning withholding tax procedures), the qualified intermediary has sufficient information in its files to indicate that the holder is a non-U.S. holder and the intermediary complies with IRS requirements. Special rules may apply with respect to notes held by a foreign partnership. Prospective investors, including foreign partnerships and their partners and holders who hold their senior notes through a qualified intermediary, should consult their tax advisers regarding possible reporting requirements.

If a non-U.S. holder cannot satisfy the requirements of the ‘‘portfolio interest’’ exemption described above, payments of interest made to such holder generally will be subject to a 30% withholding tax (or such lower rate as may be provided by an applicable income tax treaty between the United States and a foreign country) unless another exemption applies and such holder complies with the relevant certification requirements. Any prospective investor who could not satisfy the portfolio interest exemption requirements described above should consult its tax advisors prior to making an investment in the senior notes.

If a non-U.S. holder is engaged in a trade or business in the United States and interest on the senior notes is effectively connected with the conduct of such trade or business and, if required by an applicable income tax treaty, is attributable to a U.S. permanent establishment, such holder, although exempt from U.S. federal withholding tax (by reason of the delivery of a properly completed IRS Form W-8ECI or suitable substitute), will be subject to U.S. federal income tax on such interest in the same manner as if it were a U.S. person. In addition, if such holder is a foreign corporation, it may be subject to a branch profits tax equal to 30% (or lesser rate under an applicable income tax treaty) of its effectively connected earnings and profits, as defined in the Code, for the taxable year, subject to adjustments.

S-16

Table of Contents

Subject to the discussion of backup withholding below, any capital gain realized by a non-U.S. holder upon the sale, exchange or retirement of senior notes will not be subject to U.S. federal income or withholding taxes unless: (i) such gain is effectively connected with a U.S. trade or business of the holder (and, if required by an applicable income tax treaty, is attributable to a U.S. permanent establishment); or (ii) in the case of an individual, such holder is present in the United States for 183 days or more in the taxable year of the sale, exchange or retirement and certain other conditions are met.

Backup Withholding and Information Reporting

Backup withholding and information reporting requirements may apply to certain payments of principal, premium, if any, and interest on senior notes and to certain payments of proceeds of the sale or retirement of senior notes. We, our paying agent or certain other parties, as the case may be, will be required to withhold tax from any payment that is subject to backup withholding at a current rate of 28% of such payment if the holder fails to furnish his taxpayer identification number (social security number or employer identification number), to certify that such holder is not subject to backup withholding, or to otherwise comply with the applicable requirements of the backup withholding rules. Certain holders (including, among others, corporations) are not subject to the backup withholding and information reporting requirements.

Backup withholding and information reporting generally will not apply to payments made by us or our agent (in its capacity as such) to a holder of senior notes who has provided the required certification under penalties of perjury that such holder is not a U.S. person as set forth in clause (4) under ‘‘—Non-U.S. Holders’’ or has otherwise established an exemption (provided that neither we nor such agent has actual knowledge or reason to know that the holder is a U.S. person or that the conditions of any other exemption are not in fact satisfied). However, we and other payors may be required to report payments of interest on your senior notes on IRS Form 1042-S even if the payments are not otherwise subject to information reporting requirements.

Any amounts withheld under the backup withholding rules from a payment to a holder may be claimed as a credit against such holder’s U.S. federal income tax liability and, if withholding results in an overpayment of tax, the holder may be entitled to a refund, provided the required information is timely furnished to the IRS. Holders should consult their own tax advisors regarding the filing of a U.S. tax return and the claiming of a credit or refund of such backup withholding taxes.

UNDERWRITING

We and the underwriters for the offering named below have entered into an underwriting agreement with respect to the senior notes. Subject to certain conditions, each underwriter has severally agreed to purchase the principal amount of the senior notes indicated in the following table. Citigroup Global Markets Inc. and Merrill Lynch, Pierce, Fenner & Smith Incorporated are the representatives of the underwriters.

Underwriters			Principal Amount of Senior Notes
Citigroup Global Markets Inc.				$
Merrill Lynch, Pierce, Fenner & Smith                 Incorporated				$
Morgan Stanley & Co. Incorporated				$
UBS Securities LLC				$
Wachovia Capital Markets, LLC				$
Total				$

The underwriters are committed to take and pay for all of the senior notes being offered, if any are taken.

Over-Allotment Option

In addition, we have granted to the underwriters an option, exercisable for 30 days from the date of this prospectus supplement, to purchase up to an additional 15% of the total aggregate principal amount of senior notes offered hereby at the public offering price less the underwriting discounts and commissions. The underwriters may exercise the option solely for the purpose of covering over-allotments, if any, in connection with this offering. To the extent the option is exercised, each underwriter must purchase a number of additional senior notes approximately proportionate to that underwriter’s initial purchase commitment. If the underwriters exercise their over-allotment option in full, the total price to the public would be $                , the total underwriting discounts and commissions would be $                and the total net proceeds, before deducting expenses, to us would be $                .

Commissions and Discounts

An underwriting discount of                % per senior note will be paid by CBS Corp.; provided, however, that for sales to certain institutions, an underwriting discount of                % per senior note will be paid by CBS Corp. The following table shows the total underwriting discounts and commissions that we are to pay to the underwriters in connection with this offering based on an average weighted underwriting discount for retail and institutional sales of                 % (                % if the over-allotment option is exercised in full). These amounts are shown assuming both no exercise and full exercise of the underwriters’ option to purchase additional senior notes. Any senior notes sold pursuant to the over-allotment option will be sold only to retail investors.

Senior notes sold by the underwriters to the public will initially be offered at the initial public offering price set forth on the cover of this prospectus supplement. Any senior notes sold by the underwriters to securities dealers may be sold at a discount from the initial public offering price of up to             % (            % in the case of sales to certain institutions) of the principal amount of the senior notes. Any such securities dealers may resell any senior notes purchased from the underwriters to certain other brokers or dealers at a discount from the initial public offering price of up to             % (            % in the case of sales to certain institutions) of the principal amount of the senior notes. These

S-18

Table of Contents

discounts will also apply to any senior notes purchased pursuant to the over-allotment option described below. If all the senior notes are not sold at the initial public offering price, the underwriters may change the offering price and the other selling terms.

New Issue of Senior Notes

The senior notes are a new issue of securities with no established trading market. We intend to list the senior notes on the New York Stock Exchange. We expect trading in the senior notes on the New York Stock Exchange to begin within 30 days after the original issue date. The senior notes are expected to trade ‘‘flat.’’ This means that purchasers will not pay, and sellers will not receive, any accrued and unpaid interest on the senior notes that is not included in the trading price. Currently there is no public market for the senior notes.

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

Price Stabilization and Short Positions

In connection with the offering, the underwriters may purchase and sell senior notes in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of senior notes than they are required to purchase in the offering. Stabilizing transactions consist of certain bids or purchases made for the purpose of preventing or retarding a decline in the market price of the senior notes while the offering is in progress.

The underwriters also may impose a penalty bid.  This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives have repurchased senior notes sold by or for the account of such underwriter in stabilizing or short covering transactions.

These activities by the underwriters may stabilize, maintain or otherwise affect the market price of the senior notes. As a result, the price of the senior notes may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the underwriters at any time. These transactions may be effected in the over-the-counter market or otherwise.

Selling Restrictions

General

The senior notes are being offered for sale in the United States and in jurisdictions outside the United States, subject to applicable law.

	•	in any other circumstances which do not require the publication by CBS Corp. or CBS Operations of a prospectus pursuant to Article 3 of the Prospectus Directive.

For the purposes of this provision, the expression ‘‘offer of senior notes to the public’’ in relation to any senior notes in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the senior notes to be offered so as to enable an investor to decide to purchase or subscribe for the senior notes, as the same may be varied in the Member State by any measure implementing the Prospectus Directive in that Member State, and the expression ‘‘Prospectus Directive’’ means Directive 2003/71/EC and includes any relevant implementing measure in each Relevant Member State.

DESCRIPTION OF THE DEBT SECURITIES

The following description of CBS Corp.’s debt securities to be issued under the debt indentures summarizes the general terms and provisions of its debt securities to which any prospectus supplement may relate. The following description also describes the specific terms of CBS Corp.’s debt securities and the extent, if any, to which the general provisions summarized may apply to any series of its debt securities in the prospectus supplement relating to such series. References to ‘‘senior debt securities’’ are references to the senior debt securities that may be issued under the senior indenture; references to ‘‘senior subordinated debt securities’’ are references to the senior subordinated debt securities that may be issued under the senior subordinated indenture; and references to ‘‘debt securities’’ are references to both the senior debt securities and the senior subordinated debt securities.

CBS Corp. may issue its senior debt securities from time to time, in one or more series under a senior indenture between CBS Corp. and The Bank of New York, as senior trustee, or another senior trustee named in a prospectus supplement. We refer to this indenture as the ‘‘senior indenture.’’ The senior indenture is filed as an exhibit to the registration statement of which this prospectus is a part. CBS Corp. may issue its senior subordinated debt securities from time to time, in one or more series under a senior subordinated indenture between CBS Corp. and The Bank of New York, as senior subordinated trustee, or another senior subordinated trustee named in a prospectus supplement. We refer to this indenture as the ‘‘senior subordinated indenture.’’ The senior subordinated indenture is filed as an exhibit to the registration statement of which this prospectus is a part. Together the senior indenture and the senior subordinated indenture are referred to as the ‘‘debt indentures.’’ The trustee under the senior indenture is called the ‘‘senior debt trustee,’’ and the trustee under the senior subordinated indenture is called the ‘‘senior subordinated debt trustee’’. Together the senior debt trustee and the senior subordinated debt trustee are called the ‘‘debt trustees’’.

None of the indentures limits 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 CBS Corp. and may be payable in any currency or currency unit designated by CBS Corp.

General

CBS Corp. will issue debt securities from time to time and offer its debt securities on terms determined by market conditions at the time of their sale. CBS Corp. 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. CBS Corp. will describe the material United States federal income tax consequences and other special considerations applicable to any substantially discounted debt securities in a related prospectus supplement.

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

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

	•	the percentage of the principal amount at which CBS Corp. will issue the debt securities;

Table of Contents

	•	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;

	•	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 CBS Corp.’s election or the purchaser’s election, the manner in which the election may be made;

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

	•	any other specific terms of the debt securities not inconsistent with the applicable debt indenture.

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

Unless specified otherwise in a prospectus supplement, the principal of, premium 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, CBS Corp. 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, CBS Corp. or its agents.

Unless specified otherwise in a prospectus supplement, CBS Corp. 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 CBS Corp. 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.

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

Guarantees

CBS Operations 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.

Table of Contents

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 CBS Operations. 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 CBS Operations 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 CBS Operations with the intent to hinder, delay or defraud any present or future creditor or (y) CBS Operations did not receive fair consideration or reasonably equivalent value for issuing its guarantee and CBS Operations (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 CBS Operations 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 CBS Operations’ other creditors. To the extent any guarantee issued by CBS Operations was voided as a fraudulent conveyance or held unenforceable for any other reason, the holders of any debt securities guaranteed by CBS Operations could cease to have any claim against CBS Operations and would be creditors solely of CBS Corp.

We and CBS Operations believe that the issuances of the guarantees by CBS Operations 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 senior debt securities and senior subordinated securities and, if applicable, the related guarantees, neither our counsel, counsel for CBS Operations nor counsel for any initial purchaser or underwriter will express any opinion as to federal or state laws relating to fraudulent transfers.

Ranking

The senior debt securities will be unsecured senior obligations of CBS Corp. and will rank equally in right of payment with all of CBS Corp.’s other unsecured and unsubordinated indebtedness. The guarantees on the senior debt securities will be unsecured senior obligations of CBS Operations and will rank equally in right of payment with all of CBS Operations’ other unsecured and unsubordinated indebtedness.

The senior subordinated debt securities will be unsecured senior subordinated obligations of CBS Corp. and will be subordinated in right of payment to CBS Corp.’s senior indebtedness. The guarantees on the senior subordinated debt securities will be unsecured senior subordinated obligations of CBS Operations and will be subordinated in right of payment to CBS Operations’ senior indebtedness.

The debt securities and the guarantees will be effectively subordinated to any secured indebtedness of CBS Corp. or CBS Operations, 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 CBS Corp., CBS Operations or their respective subsidiaries can incur.

In addition, both CBS Operations and CBS Corp. 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 CBS Corp. and CBS Operations 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 CBS Corp. or CBS Operations to obtain cash required to pay CBS Corp.’s debt service obligations, including payments on the debt securities, or CBS Operations’ payment obligations under the guarantees. The debt securities (whether senior or subordinated obligations of CBS Corp.) will be structurally subordinated to all obligations of CBS Corp.’s subsidiaries (other than CBS Operations, to

Table of Contents

the extent such debt securities are guaranteed) including claims with respect to trade payables. The guarantees (whether senior or subordinated obligations of CBS Operations) will be structurally subordinated to all obligations of CBS Operations’ subsidiaries, including claims with respect to trade payables. This means that holders of the debt securities of CBS Corp. will have a junior position to the claims of creditors of CBS Corp.’s subsidiaries (other than CBS Operations, to the extent such debt securities are guaranteed) on the assets and earnings of such subsidiaries. Holders of guarantees of CBS Operations, if any, will have a junior position to the claims of creditors of CBS Operations’ subsidiaries on the assets and earnings of such subsidiaries and will have no claim by virtue of such guarantees against CBS Corp. or any subsidiary of CBS Corp. that is not a subsidiary of CBS Operations. As of December 31, 2006, CBS Corp.’s subsidiaries, other than CBS Operations, had approximately $171.3 million of indebtedness outstanding, while CBS Operations’ subsidiaries had approximately $69.9 million of indebtedness outstanding.

CBS Corp. 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. CBS Corp. 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 CBS Corp. if the debt securities are offered and sold directly by it. Ownership of beneficial interests in a global security will be limited to persons that have accounts with the applicable depositary participants or persons that hold interests through these participants. Ownership of beneficial interests in a global security will be shown on, and the transfer of that ownership will be effected only through, records maintained by:

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

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

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:

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

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

	•	not be considered the owners or holders thereof under the applicable debt indenture governing the debt securities.

Further Issues

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

Payment and Paying Agents

Payments of principal of, any premium on, and any interest on individual debt securities represented by a global security registered in the name of a depositary or its nominee will be made to the depositary or its nominee as the registered owner of the global security representing the debt securities. Neither CBS Corp., the debt trustee, any paying agent, nor the security registrar for the debt securities will have any responsibility or liability for the records relating to or payments made on account of beneficial ownership interests of the global security for the debt securities or for maintaining, supervising or reviewing any records relating to the beneficial ownership interests.

CBS Corp. expects that the depositary for a series of debt securities or its nominee, upon receipt of any payment of principal, premium or interest in respect of a permanent global security representing any of the debt securities, will immediately credit participants’ accounts with payments in amounts proportionate to their beneficial interests in the principal amount of the global security for the debt securities as shown on the records of the depositary or its nominee. CBS Corp. 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 debt indentures, CBS Corp. and CBS Operations 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 CBS Corp. and CBS Operations meeting all of the following conditions:

	•	the resulting entity (other than CBS Corp. or CBS Operations) must agree through a supplemental indenture to be legally responsible for the debt securities;

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

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

	•	CBS Corp. or CBS Operations, as the case may be, must deliver certain certificates and documents to the debt trustee; and

	•	CBS Corp. and CBS Operations, if applicable, must satisfy any other requirements specified in the prospectus supplement relating to a particular series of debt securities.

We and CBS Operations 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 CBS Corp. or CBS Operations 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 CBS Corp. or CBS Operations, as the case may be, under the debt indentures and CBS Corp. or CBS Operations, as the case may be, shall be discharged from all of its obligations under the debt indentures.

Limitations on Liens

We covenant in the debt indentures that we will not create, assume or permit any Lien on any of our properties or assets, unless we secure the debt securities at least equally and ratably to the

9

Table of Contents

secured Indebtedness. The foregoing only applies to Liens that in the aggregate exceed 15% of our total consolidated assets, reduced by the Attributable Debt related to any permitted sale and leaseback arrangement. See ‘‘—Limitations on Sale and Leaseback Transactions’’ below. The restrictions do not apply to Capitalized Leases or Indebtedness that is secured by:

	•	Liens existing, in the case of any debt securities, on the date such debt securities are issued;

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

	•	Liens in favor of us or our Subsidiaries; and

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

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

Limitations on Sale and Leaseback Transactions

We covenant in the 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 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:

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

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

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

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

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

The term ‘‘Attributable Debt,’’ with regard to a sale and leaseback arrangement of a Principal Property, is defined in the 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 debt indentures.

The term ‘‘Principal Property’’ is defined in the 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 debt securities will have specified rights if an Event of Default (as defined below) occurs in respect of the debt securities of that series, as described below.

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

	•	CBS Corp. does not pay interest on a debt security of such series within 30 days of its due date;

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

	•	CBS Corp. remains in breach of a covenant or warranty in respect of the senior indenture for 60 days after CBS Corp. receives a written notice of default; the notice must be sent by either the debt trustee or holders of at least 25% in principal amount of a series of outstanding debt securities; or

	•	CBS Corp. or CBS Operations, if guarantees are issued, files for bankruptcy, or other events of bankruptcy specified in the applicable debt indenture, insolvency or reorganization occur.

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

Except in cases of default, where the debt trustee has special duties, a debt trustee is not required to take any action under a debt indenture at the request of holders unless the holders offer the debt trustee reasonable protection from expenses and liability satisfactory to the debt trustee. If a reasonable indemnity is provided, the holders of a majority in principal amount of a series of debt securities may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the debt trustee. The debt trustee may refuse to follow those directions in certain circumstances specified in the applicable 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 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 debt securities, the following must occur:

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

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

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

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

Table of Contents

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

Modification of the Debt Indentures

The debt indentures provide that CBS Corp., CBS Operations, if applicable, and the debt trustee may, without the consent of any holders of debt securities, enter into supplemental indentures for the purposes, among other things, of:

	•	adding to CBS Corp.’s or CBS Operations’ covenants;

	•	adding additional events of default;

	•	change or eliminate any provisions of the debt indenture so long as there are no holders entitled to the benefit of the provisions;

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

	•	curing ambiguities or inconsistencies in the debt indenture or making any other provisions with respect to matters or questions arising under the debt indentures.

With specific exceptions, the debt indentures or the rights of the holders of the debt securities may be modified by CBS Corp., CBS Operations and the debt trustee with the consent of the holders of a majority in aggregate principal amount of the debt securities of each series affected by the modification then outstanding, but no modification may be made without the consent of the holders of each outstanding debt security affected which would:

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

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

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

	•	change any obligation of CBS Corp. to pay additional amounts;

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

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

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

	•	reduce the obligations of CBS Operations, if any, in respect of the due and punctual payment of principal, premium and interest, if any.

Meetings

The debt indentures contain provisions for convening meetings of the holders of the debt securities of any or all series. Specific terms related to such meetings of the holders are described in the debt indentures.

Defeasance and Covenant Defeasance

CBS Corp. may elect either (i) to defease and be discharged (and, if applicable, to have CBS Operations defeased and discharged) from any and all obligations with respect to the debt securities (except as otherwise provided in the debt indentures) (‘‘defeasance’’) or (ii) to be released from its

12

---

Table of Contents

obligations with respect to certain covenants that are described in the debt indentures (‘‘covenant defeasance’’), upon the deposit with the 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 terms will provide money in an amount sufficient, without reinvestment, to pay the principal of, premium, if any, and interest on the debt securities of such series to maturity or redemption, as the case may be, and any mandatory sinking fund or analogous senior payments thereon. As a condition to defeasance or covenant defeasance, CBS Corp. must deliver to the debt trustee an opinion of counsel to the effect that the holders of the debt securities of such series will not recognize income, gain or loss for United States federal income tax purposes as a result of such defeasance or covenant defeasance and will be subject to United States federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance or covenant defeasance had not occurred. Such opinion of counsel, in the case of defeasance under clause (i) above, must refer to and be based upon a ruling of the Internal Revenue Service or a change in applicable United States federal income tax law occurring after the date of the debt indentures.

CBS Corp. may exercise its defeasance option with respect to the debt securities of any series notwithstanding its prior exercise of its covenant defeasance option. If CBS Corp. exercises its defeasance option, payment of the debt securities of such series may not be accelerated because of an event of default and the guarantees relating to such debt securities will cease to exist. If CBS Corp. exercises its covenant defeasance option, payment of the debt securities of such series may not be accelerated by reference to any covenant from which CBS Corp. 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 debt securities of such series, in that the required deposit in the defeasance trust is based upon scheduled cash flows rather than market value, which will vary depending upon interest rates and other factors.

Notices

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

Title

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

Replacement of Debt Securities

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

Governing Law

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

Concerning the Debt Trustees

CBS Corp. will identify the debt trustees in the relevant prospectus supplement. In specific instances, CBS Corp. or the holders of a majority of the then outstanding principal amount of the debt securities issued under a debt indenture may remove the debt trustee and appoint a successor

13

Table of Contents

trustee. The debt trustee may become the owner or pledgee of any of the debt securities with the same rights, subject to conflict of interest restrictions, it would have if it were not the debt trustee. The 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 debt trustee may also serve as trustee under other indentures relating to securities issued by CBS Corp. or its affiliated companies and may engage in commercial transactions with CBS Corp. and its affiliated companies. The initial debt trustee under each debt indenture is The Bank of New York.

Senior Debt Securities

CBS Corp. will describe the specific terms of the 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 senior debt securities in the prospectus supplement relating to that series.

Senior Subordinated Debt Securities

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

Subordination.    The senior subordinated debt securities will be subordinated in right of payment to CBS Corp.’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 senior subordinated debt securities will be subordinated in right of payment to the prior payment in full of all of CBS Corp.’s senior indebtedness. CBS Corp. may not make payment of principal of, premium, if any, or interest on the senior subordinated debt securities and may not acquire, or make payment on account of any sinking fund for, the 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 senior subordinated debt securities and no acquisition of, or payment on account of a sinking fund for, the senior subordinated debt securities may be made. CBS Corp. will give prompt written notice to the senior subordinated trustee of any default under any senior indebtedness or under any agreement pursuant to which senior indebtedness may have been issued. The senior subordinated indenture provisions described in this paragraph, however, do not prevent CBS Corp. from making a sinking fund payment with 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 CBS Corp.’s dissolution, liquidation or reorganization, all senior indebtedness must be paid in full before the holders of the senior subordinated debt securities are entitled to any payments whatsoever. As a result of these subordination provisions, in the event of CBS Corp.’s insolvency, holders of the senior subordinated debt securities may recover ratably less than the holders of CBS Corp.’s senior indebtedness.

Table of Contents

For purposes of the description of the 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:

	•	indebtedness for money borrowed by it, or evidenced by securities, other than the senior subordinated debt securities or any other indebtedness which is subordinate to the senior subordinated debt securities;

	•	obligations with respect to letters of credit;

	•	indebtedness constituting a guarantee of indebtedness of others, other than any subordinated guarantees;

	•	obligations under Capitalized Leases (as defined below) (other than (x) telecommunications equipment, including satellite transponders, and (y) theme park equipment and attractions);

	•	any obligation of a third party if secured by a lien on assets; or

	•	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 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 December 31, 2006, CBS Corp.’s Senior Indebtedness totaled approximately $6.9 billion, and CBS Operations had no Senior Indebtedness, other than its guarantees of the senior debt of CBS Corp., all of which is fully and unconditionally guaranteed by CBS Operations.

Certain Definitions
