 CBS Corporation, a Delaware corporation (herein called the “Issuer” or the
“Company,” which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., or registered assigns, the principal sum of $[__________] on
June 1, 2028 at the office or agency of the Company referred to below, and to pay interest thereon on June 1,

2018 and semiannually in arrears thereafter, on June 1 and December 1 of each year (each, an “Interest Payment Date”), from November 16, 2017, or from the most
recent Interest Payment Date to which interest has been paid or duly provided for, at the rate of 3.700% per annum, until the principal hereof is paid or duly provided for. 

The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid,
in immediately available funds, to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the May 15 or
November 15, as the case may be, preceding such Interest Payment Date. Any such interest not so punctually paid or duly provided for shall forthwith cease to be payable to the Holder on such Regular Record Date, and such Defaulted Interest may
be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be
given to Holders of Securities not less than 10 days prior to such Special Record Date, or may be paid at any time in any other lawful manner, all as more fully provided in the Indenture. 

Payment of the principal of and interest on this Security will be made at the Corporate Trust Office of the Trustee or such other office or
agency of the Company as may be designated for such purpose, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that each installment
of interest and principal on this Security may at the Company’s option be paid by check to the payee or in immediately available funds by transfer to an account maintained by the payee located in the United States. 

Any payment of principal or interest required to be made on a day that is not a Business Day need not be made on such day, but may be made on
the next succeeding Business Day and no interest shall accrue as a result of such delayed payment. For purposes of this Security, “Business Day” means any day that is not a Saturday or Sunday and that, in The City of New York, is not a day
on which banking institutions are generally authorized or obligated by law or executive order to close. 
 General. This Security is
one of a duly authorized issue of securities of the Company (herein called the “Securities”), unlimited in aggregate principal amount, issued and to be issued in one or more series under the Indenture, dated as of November 16, 2017,
among the Company, CBS Operations Inc. (the “Guarantor”) and Deutsche Bank Trust Company Americas, as trustee (the “Trustee”) (as supplemented or amended from time to time, the “Indenture”), to
which Indenture and the respective resolutions of the Company’s board of directors or resolutions pursuant to the authority of the board of directors, an Officer’s Certificate and/or indentures supplemental thereto, as the case may be,
reference is hereby made for a statement of the respective rights, limitations of rights, duties, obligations and immunities thereunder of the Company, the Trustee and the Holders of the Securities, and of the terms upon which the Securities are,
and are to be, authenticated and delivered. This Security is one of a series designated as 3.700% Senior Notes due 2028, limited in aggregate principal amount as of the date hereof to $500,000,000. 

Authorized Denominations. The Securities of this series are issuable only in registered form without coupons in minimum denominations
of $2,000 and in integral multiples of $1,000. 
 Book-Entry Security. This Security is a “book-entry” Security and is
being registered in the name of Cede & Co., as nominee of DTC. Subject to the terms of the Indenture, this Security will be held by DTC or its nominee, and beneficial interests will be held by beneficial owners through the book-entry
facilities of DTC or its nominee in minimum denominations of $2,000 and in integral multiples of $1,000. As long as this Security is registered in the name of DTC or its nominee, the Trustee will make payments of principal of and interest on this
Security by wire transfer of immediately available funds to DTC or its nominee. Notwithstanding the above, upon the maturity of this Security, the principal, together with accrued interest thereon, will be paid in immediately available funds upon
surrender of this Security at the Corporate Trust Office of the Trustee or such other offices or agencies appointed by the Trustee for that purpose or such other locations provided in the Indenture.

Registration Rights Agreement, dated as of November 16, 2017, among the Company, the Guarantor and Credit Suisse Securities (USA) LLC, J.P. Morgan Securities LLC, Mizuho Securities USA LLC and RBC Capital Markets, LLC, as representatives of the

with the provisions set forth herein for the payment of regular interest. 
 Event of Default. If an Event of Default with respect to
Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. 

Redemption and Maturity. The Securities of this series are not subject to any sinking fund and are subject to redemption prior to
maturity as set forth below. 
 Optional Redemption. Commencing on March 1, 2028 (the “Par Call Date”), the
Securities of this series may be redeemed, at the option of the Company, in whole or in part, at any time and from time to time on not less than 15 nor more than 45 days’ prior notice, at a Redemption Price equal to the sum of 100% of the
principal amount redeemed and any accrued and unpaid interest to the Redemption Date. Prior to the Par Call Date, the Securities of this series may be redeemed, at the option of the Company, in whole or in part, at any time and from time to time on
not less than 15 nor more than 45 days’ prior notice, at a Redemption Price equal to the greater of: 
 (a) 100% of the principal
amount of the Securities to be redeemed; and 
 (b) the sum of the present values of the remaining scheduled payments of principal and
interest on the Securities to be redeemed, assuming such Securities matured on the Par Call Date, from the Redemption Date to the Par Call Date (exclusive of any interest accrued to the Redemption Date), discounted to the Redemption Date on a
semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate, plus 25 basis points; 

plus, in each case, any interest accrued but not paid on the Securities to be redeemed to the Redemption Date. Notwithstanding the foregoing,
installments of interest on applicable Securities that are due and payable on Interest Payment Dates falling on or prior to a Redemption Date will be payable on the Interest Payment Date to the registered holders as of the close of business on the
relevant Regular Record Date. In the event of a deposit or withdrawal of an interest in this Security, including an exchange, transfer, redemption or conversion of this Security in part only, the Trustee, as custodian of the Depositary, shall make
an adjustment on its records to reflect such deposit or withdrawal in accordance with the rules and procedures of the Depositary. 

“Comparable Treasury Issue” means the United States Treasury security or securities selected by an Independent Investment
Banker as having an actual or interpolated maturity comparable to the remaining term (the “Remaining Life”) of the Securities to be redeemed, assuming such Securities matured on the Par Call Date, that would be utilized, at the time
of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of a comparable maturity to the Remaining Life of such Securities. 

“Comparable Treasury Price” means, with respect to any Redemption Date, (i) the average of four Reference
Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (ii) if the Independent Investment Banker obtains fewer than four such Reference Treasury Dealer
Quotations, the average of all such quotations, or (iii) if only one Reference Treasury Dealer Quotation is received, such quotation.

 “Independent Investment Banker” means a Reference Treasury Dealer appointed by
the Company. 
 “Reference Treasury Dealer” means a primary U.S. Government securities dealer in the United States

Independent Investment Banker by such Reference Treasury Dealer at 3:30 p.m., New York City time, on the third Business Day preceding such Redemption Date. 

“Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to: 

(a) the yield, under the heading that represents the average for the immediately preceding week, appearing in the most recently published
statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities
adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue; provided that if no maturity is within three months before or after the Remaining Life,
yields for the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Treasury Rate will be interpolated or extrapolated from those yields on a straight-line basis rounding to the nearest
month; or 
 (b) if that release, or any successor release, is not published during the week preceding the calculation date or does not
contain such yields, the rate per year equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the
Comparable Treasury Price for that Redemption Date. 
 The Treasury Rate will be calculated at 5:00 p.m. (New York City time) on the third
Business Day preceding such Redemption Date by the Reference Treasury Dealer. 
 In the case of any partial redemption, selection of the
Securities of this series for redemption will be made by the Trustee in compliance with the requirements of the principal U.S. national securities exchange, if any, on which the Securities of this series are listed or, if they are not listed on a
U.S. national securities exchange, by lot or by such other method as the Trustee in its sole discretion deems to be fair and appropriate. 

Offers to Repurchase. Upon the occurrence of a Change of Control Repurchase Event (as defined below) in respect of the Securities of

to each Holder, with a copy to the Trustee stating: 
 (i) that a Change of Control Change Repurchase Event has occurred or may occur and

(iv) the purchase price (including the amount of accrued and unpaid interest, if any) for each Security and the date on which the Change of

If such notice is mailed prior to the date of consummation of the Change of Control, the notice shall also state that the Change of Control

Holder a new Security of like tenor equal in principal amount to any unpurchased portion of the Security surrendered. Any Securities of this series not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. Upon the

applicable in connection with the repurchase of Securities of this series as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with the terms of the Change of Control
Repurchase Event provisions of the Securities of this series the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the Change of Control Repurchase Event
provisions of the Securities of this series by virtue thereof.

As set forth in, and subject to, the provisions of the Indenture, no Holder of any Security of this series will have any right to institute
