Redemption Date (which date shall be no earlier than 30 days and no later than 60 days from the date such notice is sent), together with such other matters as may be advisable in the Company’s discretion or required by this Indenture or
permitted pursuant to this Article 11. The notice shall, if sent prior to the occurrence of the Change of Control Event, state that the Change of Control Redemption is conditioned on the Change of Control Event occurring on or prior to the

trust, more than 50% of the trustees of such trust consist of Redstone Family Members.

means the display that appears on Reuters Page LIBOR01 or any page as may replace such page on such service (or on any similar, successor or substitute page of such service, or any successor to or substitute for such service providing rate

 “S&P” means
S&P Global Ratings, a division of S&P Global Inc. 
 “Tax Event” means, with respect to a series of
Debentures, when the Company has received an opinion of nationally recognized counsel experienced in U.S. federal income tax matters that, as a result of: 

(1)     any amendment to, clarification of, or change, including any announced prospective change, in the
laws or treaties of the U.S. or any of its political subdivisions or taxing authorities, or any regulations under those laws or treaties; 

(2)     an administrative action, which means any judicial decision or any official administrative
pronouncement, ruling, regulatory procedure, notice or announcement including any notice or announcement of intent to issue or adopt any administrative pronouncement, ruling, regulatory procedure or regulation; 

(3)     any amendment to, clarification of, or change in the official position or the interpretation of any
administrative action or judicial decision or any interpretation or pronouncement that provides for a position with respect to an administrative action or judicial decision that differs from the previously generally accepted position, in each case
by any legislative body, court, governmental authority or regulatory body, regardless of the time or manner in which that amendment, clarification or change is introduced or made known; or 

(4)     a threatened challenge asserted in writing in connection with an audit of the Company or any of its
Subsidiaries, or a publicly-known threatened challenge asserted in writing against any other taxpayer that has raised capital through the issuance of securities that are substantially similar to the Debentures of such series, 

  
 7 

 which amendment, clarification, or change is effective or the administrative action is taken or
judicial decision, interpretation or pronouncement is issued or threatened challenge is asserted or becomes publicly-known after February 23, 2017, there is more than an insubstantial risk that interest payable by the Company on such series of
Debentures is not deductible, or within 90 days would not be deductible, in whole or in part, by the Company for U.S. federal income tax purposes. 

“Three-Month LIBOR” shall be determined by the Calculation Agent in accordance with the following provisions:

for deposits in U.S. dollars having a maturity of three months commencing on the related Interest Reset Date that appears on Reuters Page LIBOR01 as of 11:00 a.m., London time, on that Interest Determination Date. If no such rate appears, then
Three-Month LIBOR, in respect of that Interest Determination Date, shall be determined in accordance with the provisions described in (2) below. 

(2) With respect to an Interest Determination Date on which no rate appears on Reuters Page LIBOR01, the Company shall request
the principal London offices of each of four major reference banks in the London interbank market (which may include Affiliates of the Underwriters), as selected by the Company, to provide its offered quotation (expressed as a percentage per annum)
for deposits in U.S. dollars for the period of three months, commencing on the related Interest Reset Date, to prime banks in the London interbank market at approximately 11:00 a.m., London time, on that Interest Determination Date and in a
principal amount that is representative for a single transaction in U.S. dollars in that market at that time. If at least two quotations are provided, then Three-Month LIBOR on that Interest Determination Date shall be the arithmetic mean of those
quotations. If fewer than two quotations are provided, then Three-Month LIBOR on the Interest Determination Date shall be the arithmetic mean of the rates quoted at approximately 11:00 a.m., in the City of New York, on the Interest Determination
Date by three major banks in the City of New York (which may include Affiliates of the Underwriters) selected by the Company for loans in U.S. dollars to leading European banks, for a period of three months, commencing on the related Interest Reset
Date, and in a principal amount that is representative for a single transaction in U.S. dollars in that market at that time. If at least two such rates are so provided, Three-Month LIBOR on the Interest Determination Date shall be the arithmetic
mean of such rates. If fewer than two such rates are so provided, Three-Month LIBOR on the Interest Determination Date shall be Three-Month LIBOR in effect with respect to the immediately preceding Interest Determination Date. 

“Twentieth Supplemental Indenture” means the twentieth supplemental indenture dated as of February 28, 2017,

thereof the following: 
 “Default” means, with respect to the Debentures of any series, the following event:
default in the performance or breach of any covenant or warranty of the Company in this Indenture (other than (i) a covenant or warranty a default in whose performance or whose breach is addressed in Section 501 or (ii) which has
expressly been included in this Indenture solely for the benefit of one or more series of Securities other than the Debentures), and continuance of such default or breach for a period of 90 days after specified written notice to the Company by the
Trustee, or to the Company and the Trustee by the Holders of at least 25% in principal amount of the Outstanding Debentures of such series. 
 SECTION
2.8     The following Section 305A is hereby added to the Indenture: 
 SECTION 305A. Book-Entry
Provisions for Global Securities. (a) Each Global Security initially shall (i) be registered in the name of the Depositary for such Global Security or the nominee of such Depositary, (ii) be delivered to the Trustee, as custodian
for such Depositary, and (iii) bear legends as set forth on the face of the form of the NC5 Debenture or of the form of the NC10 Debenture, as applicable. 

Members of, or Participants in, the Depositary (“Agent Members”) shall have no rights under this Indenture
with respect to any Global Security held on their behalf by the Depositary, or the Trustee as its custodian, or under such Global Security, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as
the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification,
proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a holder of any Security. 

(b)    Transfers of a Global Security shall be limited to transfers of such Global Security in whole, but
not in part, to the Depositary, its successors or their respective nominees. Transfers of interests in one Global Security to parties who will hold the interests through the same Global Security will be effected in the ordinary way in accordance
with the rules and operating procedures of the applicable Depositary. The provisions of the “Operating Procedures of the Euroclear System” and “Terms and 

  
 9 

 
Conditions Governing Use of Euroclear” (or any successors thereto) of Euroclear and the “General Terms and Conditions of Clearstream” and “Customer Handbook” (or any
successors thereto) of Clearstream shall be applicable to interests in the Global Securities that are held by Agent Members through Euroclear and Clearstream. 

(c)    Any beneficial interest in one of the Global Securities that is transferred to a person who takes
delivery in the form of an interest in another Global Security will, upon transfer, cease to be an interest in such Global Security and become an interest in such other Global Security and, accordingly, will thereafter be subject to all transfer
restrictions, if any, and other procedures applicable to beneficial interests in such other Global Security for so long as it remains such an interest. 

(d)    In connection with any transfer of a portion of the interests in a Global Security to beneficial
owners pursuant to paragraph (c) of this Section 305A, the Registrar shall reflect on its books and records the date and a decrease in the principal amount of such Global Security in an amount equal to the principal amount of the
interest in such Global Security to be transferred. 
 (e)    In connection with the transfer of the
Global Securities, in whole, to beneficial owners pursuant to paragraph (b) of this Section 305A, the Global Securities shall be deemed to be surrendered to the Trustee for cancellation. 

(f)    The registered holder of a Global Security may grant proxies and otherwise authorize any person,
including Agent Members and persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Debentures. 

(g)    The Debentures are initially solely issuable as Global Securities. Registered Securities shall be
physically transferred to all beneficial owners in definitive form in exchange for their beneficial interests in a Global Security, if the Depositary with respect to such Global Securities notifies the Company that it is unwilling or unable to
continue as Depositary for such Global Security, as the case may be, and a successor Depositary is not appointed by the Company within 90 days of such notice. 

(h)    All Debentures issued upon any transfer or exchange of Debentures shall be valid, legally
enforceable obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Debentures surrendered upon such transfer or exchange. 

SECTION 2.9     Section 106 of the Indenture is hereby amended by inserting immediately following the words, “at his address as
it appears in the Security Register”, the following: “or in accordance with the procedures of the applicable Depositary, if any”. 
 SECTION
2.10    The first paragraph of Section 1103 of the Indenture is hereby amended and restated as follows: 

SECTION 1103. Selection by Trustee of Securities to Be Redeemed. If less than all the Securities of any series are to be
redeemed, the particular Securities to be 

  
 10 

 
redeemed shall be selected not more than 60 days prior to the Redemption Date in accordance with the procedures of the Depositary or, in the case of certificated Securities, by the Trustee, from
the Outstanding Securities of such series not previously called for redemption, by such method as the Trustee shall deem appropriate; provided that such method complies with the rules of any national securities exchange or quotation system on which
the Securities are then listed, and which may provide for the selection for redemption of portions of the principal of Securities of such series; provided, however, that no such partial redemption shall reduce the portion of the principal amount of
a Security not redeemed to less than the minimum authorized denomination for Securities of such series established pursuant to Section 301. 
 SECTION
2.11    The following Section 301A is hereby added to the Indenture: 
 SECTION 301A. Further Issues. The
Company may from time to time, without notice to or the consent of the Holders of the Debentures, create and issue further NC5 Debentures and NC10 Debentures ranking equally and ratably in all respects with the Debentures of such series, as the case
may be, or in all respects except for the payment of interest accruing prior to the issue date or except, as applicable, for the first payment of interest following the issue date of those further Debentures. Any such further Debentures shall be
consolidated with and form a single series with the NC5 Debentures or the NC10 Debentures issued on the date of the Twentieth Supplemental Indenture, as the case may be, and shall have the same terms as to status, CUSIP number or otherwise as such
series of Debentures; provided, however, that any such further Debentures that are not fungible for U.S. federal income tax purposes with the NC5 Debentures or the NC10 Debentures issued on the date of the Twentieth Supplemental Indenture, as the
case may be, may be issued under a different CUSIP number. Any such further Debentures shall be issued pursuant to a Board Resolution, a supplement to this Indenture or under an Officer’s Certificate pursuant to this Indenture. 

SECTION 2.12    Section 311 of the Indenture is hereby deleted in its entirety and replaced by “SECTION 311. [Reserved.]”, and
the following Section 307A is hereby added to the Indenture: 
 SECTION 307A. Fixed-Rate and Floating Rate Period.
(a) During the Fixed-Rate Period, interest on the Debentures of each series shall be computed on the basis of a 360-day year consisting of twelve 30-day months.

 (b)     During the Floating-Rate Period, the rate of interest on the Debentures shall be set initially
or reset quarterly, as the case may be, on each Interest Reset Date, commencing February 28, 2022, in the case of the NC5 Debentures, and February 28, 2027, in the case of the NC10 Debentures. If any Interest Reset Date would fall on a day
that is not a LIBOR Business Day, the Interest Reset Date shall be postponed to the next succeeding LIBOR Business Day, except that if that LIBOR Business Day falls in the next succeeding calendar month, the Interest Reset Date shall be the
immediately preceding LIBOR Business Day. 

  
 11 

 (c)    During the Floating-Rate Period, in lieu of
Section 112, this clause (c) shall apply to the Debentures. If any Interest Payment Date, other than a Redemption Date or the maturity date, for the Debentures would fall on a day that is not a LIBOR Business Day, the Interest Payment Date
shall be postponed to the next succeeding LIBOR Business Day, except that if that LIBOR Business Day falls in the next succeeding calendar month, the Interest Payment Date shall be the immediately preceding LIBOR Business Day. If a Redemption Date
or the maturity date for the Debentures would fall on a day that is not a LIBOR Business Day, the payment of interest and principal or the applicable Redemption Price shall be made on the next succeeding LIBOR Business Day, and no interest shall
accrue after such Redemption Date or maturity date, as applicable. 
 (d)    The calculation agent for
the Debentures is the Trustee, or its successor appointed by the Company (the “Calculation Agent”). The Calculation Agent shall determine the initial interest rate for the Debentures by reference to Three-Month LIBOR on the second London
Banking Day preceding February 28, 2022, in the case of the NC5 Debentures, and February 28, 2027, in the case of the NC10 Debentures, and the interest rate for each succeeding interest reset period by reference to Three-Month LIBOR on the
second London Banking Day preceding the applicable Interest Reset Date (each, an “Interest Determination Date”). Promptly upon such determination, the Calculation Agent shall notify the Company and the Trustee (if the Calculation Agent is
not the Trustee) of the new interest rate. Upon the request of the Holder of any Debenture, the Calculation Agent shall provide the interest rate then in effect and, if determined, the interest rate that will become effective on the next Interest
Reset Date. 
 (e)    During the Floating-Rate Period, the amount of interest accrued on the Debentures
to each Interest Payment Date shall be calculated by multiplying the principal amount of the Debentures by an accrued interest factor. The accrued interest factor shall be equal to the sum of the interest factors calculated for each day in the
period for which interest is being paid. The interest factor for each day is equal to the interest rate applicable to that day divided by 360. The interest rate in effect on any Interest Reset Date shall be the applicable rate as reset on that date.
The interest rate applicable to any other day is the interest rate from the immediately preceding Interest Reset Date. 

(f)    All percentages resulting from any calculation of any interest rate for the Debentures shall be
rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with five one-millionths of a percentage point rounded upward (e.g., 9.876545% (or .09876545) would be rounded to 9.87655%
(or .0987655)), and all dollar amounts would be rounded to the nearest cent, with one-half cent being rounded upward. 

(g)    All calculations made by the Calculation Agent for the purposes of calculating interest on the
Debentures shall be conclusive and binding on the Holders of the Debentures and the Company, absent manifest error. 

(h)    With respect to the Debentures, in this Indenture the term “interest” includes quarterly
or semi-annual interest payments, as applicable, and applicable interest on interest payments incurred but not paid on the applicable Interest Payment Date. Unless the context otherwise requires, the term “interest” shall include
Additional Interest, if any.

 SECTION 2.13    Section 501 of the Indenture is hereby deleted in its entirety and replaced
by the following Section 501: 
 SECTION 501. Events of Default. “Event of Default”, wherever used
herein with respect to Debentures of any series, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment,
decree or order of any court or any order, rule or regulation of any administrative or governmental body): 

(1)    the Company does not pay the principal of, or premium, if any, on or interest on the Debentures of
such series when due and payable, at maturity, or upon redemption; 
 (2)    the Company does not pay
interest (including Additional Interest) on the Debentures of such series when due and payable and such failure to pay interest continues for 30 days (other than with respect to interest due at maturity or upon earlier redemption), subject to the
Company’s right to optionally defer interest payments pursuant to Section 1001A; 
 (3)     the
entry by a court having jurisdiction in the premises of (A) a decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable federal or state bankruptcy, insolvency, reorganization or other
similar law or (B) a decree or order adjudging the Company as bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Company under the Federal
Bankruptcy Code or any other applicable federal or state law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator (or other similar official) of the Company or of any substantial part of its property, or ordering the
winding up or liquidation of its affairs, and the continuance of any such decree or order unstayed and in effect for a period of 90 consecutive days; or 

(4)    the commencement by the Company of a voluntary case or proceeding under any applicable federal or
state bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by it to the entry of a decree or order for relief in respect of the Company in an
involuntary case or proceeding under any applicable federal or state bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against it, or the filing by it of a petition
or answer or consent seeking reorganization or relief under the Federal Bankruptcy Code or any other applicable federal or state law, or the consent by it to the filing of any such petition or to the appointment of or taking possession by a
custodian, receiver, liquidator, assignee, trustee, sequestrator (or other similar official) of the 

  
 13 

 
Company or of any substantial part of its property, or the making by it of an assignment for the benefit of creditors, or the admission by it in writing of its inability to pay its debts
generally as they become due or the taking of corporate action by the Company in furtherance of any such action. 
 For the avoidance of
doubt, the Events of Default stated in this Section 501 shall be the only Events of Default applicable to the Debentures. 

Section 503 of the Indenture is hereby amended by deleting, “The Company covenants” and inserting in its place the following:
“Subject to the Company’s right to optionally defer interest payments pursuant to Section 1001A, the Company covenants”. 

Section 601 of the Indenture is hereby amended by deleting, “of the character specified in Section 501(3)”.
Section 606 of the Indenture is hereby amended by deleting, “Section 501(5) or (6)”, and inserting in its place, “Section 501(3) or (4)”. Section 1503 of the Indenture is hereby amended by deleting,
“under Section 501(3) or Section 501(6) or otherwise”. Section 1504(2) of the Indenture is hereby amended by deleting, “insofar as paragraphs (4) and (5) of Section 501”, and inserting in its place,
“insofar as paragraphs (3) and (4) of Section 501”. 
 The following Section 501A is hereby added to the Indenture: 

SECTION 501A. Remedies Upon a Default. Notwithstanding any other provision of this Indenture, upon the occurrence and
continuance of a Default with respect to a series of Debentures, the Trustee and the Holders of the Debentures of such series shall have the same rights and remedies, and shall be subject to the same limitations, restrictions, protections and
exculpations, and the Company shall be subject to the same obligations and restrictions, in each case, as would apply if such Default was an Event of Default or an event which after notice or lapse of time or both would become an Event of Default;
provided that the principal of and accrued interest on the Debentures of such series may not be declared immediately due and payable by reason of the occurrence and continuation of a Default, and any notice of declaration or acceleration based on
such Default shall be null and void with respect to the Debentures of such series; provided, further, that in case a Default has occurred and is continuing, the Trustee shall not be subject to the requirement to exercise, with respect to the
Debentures of such series, the same degree of care as a prudent individual would exercise in the conduct of his or her own affairs, unless an Event of Default has occurred and is continuing. 

SECTION 2.14    The first paragraph of Section 502 of the Indenture is hereby amended and restated as follows: 

SECTION 502. Acceleration of Maturity; Rescission and Annulment. If an Event of Default described in clause (1) or
(2) of Section 501 with respect to the Debentures of any series at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Debentures of that
series may, and the Trustee at the request of such Holders shall, declare immediately due and payable, by a notice in writing to the Company (and to the Trustee if given by Holders) the unpaid principal of (and premium, if any) and accrued

  
 14 

 
interest in respect of any Debenture then Outstanding in that series (the “Default Amount”). Upon any such declaration, the Default Amount shall become immediately due and payable on
all Outstanding Debentures of that series. Notwithstanding any other provision of this Section 502, if an Event of Default in Sections 501(3) or 501(4) occurs, then the Default Amount shall ipso facto become and be immediately due and payable
without any declaration or other act on the part of the Trustee or any Holder. 
 SECTION 2.15    The fifth paragraph of
Section 307 of the Indenture is hereby amended by deleting the word “Any” at the start of such paragraph and inserting in place thereof the following: “Subject to the Company’s right to optionally defer interest payments
pursuant to Section 1001A, any”. 
 The following Section 1001A is hereby added to the Indenture: 

SECTION 1001A. Option to Defer Interest Payments.    (a) Notwithstanding Section 1001, so long
as no Event of Default under this Indenture with respect to the Debentures has occurred and is continuing, at the Company’s sole option, it may, on one or more occasions, defer payment of all or part of the current and accrued interest
otherwise due on any series of the Debentures by extending the interest payment period for up to five (5) consecutive years (each period, commencing on the date that the first such interest payment would otherwise have been made, an
“Optional Deferral Period”). A deferral of interest payments for a series of Debentures may not extend beyond the maturity date of such series of Debentures or end on a day other than an Interest Payment Date. Any deferred interest on the
Debentures of any series shall accrue additional interest at a rate equal to the interest rate then applicable to the Debentures of such series from the applicable Interest Payment Date to the date of payment (such additional interest accrued
thereon, “Additional Interest”), to the extent permitted under applicable law. No interest shall be due and payable on the Debentures until the end of an Optional Deferral Period, except upon a redemption of the Debentures during such
Optional Deferral Period. For the avoidance of doubt, any such deferral of payment of interest during an Optional Deferral Period in compliance with this Section 1001A shall not be deemed to be Defaulted Interest. 

At the end of an Optional Deferral Period or on any Redemption Date, the Company shall be obligated to pay all accrued and
unpaid interest, including any Additional Interest, on the applicable series of Debentures. Once the Company pays all accrued and unpaid interest payments on the Debentures of such series, including any Additional Interest, the Company may again
defer interest payments on the Debentures of such series as set forth above, but not beyond the maturity date of the Debentures of such series. 

The Company shall provide to the Trustee written notice of any optional deferral of interest at least 10 and not more than 60
Business Days prior to the earlier of (1) the next applicable Interest Payment Date or (2) the date, if any, upon which the Company is required to give notice of such Interest Payment Date or the record date therefor to any applicable
self-regulatory organization. In addition, in connection with the exercise of its option to defer interest pursuant to this Section 1001A, the Company shall deliver to the 

  
 15 

 
Trustee an Officer’s Certificate stating that no Event of Default shall have occurred and be continuing. Subject to receipt of such Officer’s Certificate, the Trustee shall promptly
forward such notice to each Holder of record of Debentures of the applicable series. 
 (b)    During an
Optional Deferral Period, subject to the exceptions set forth below, the Company shall not: 

(1)    declare or pay any dividend or make any distributions with respect to, or redeem, purchase, acquire
or make a liquidation payment with respect to, any of the Company’s capital stock; or 
 (2)    make
any payment of interest, principal or premium, if any, on or repay, repurchase or redeem any debt securities (including guarantees) issued by the Company which rank equally with or junior in right of payment to the Debentures. 

None of the foregoing in this clause (b) shall restrict: 

(1)    any of the actions set forth in the preceding sentence resulting from any reclassification of the
Company’s capital stock or the exchange or conversion of one class or series of the Company’s capital stock for another class or series of the Company’s capital stock; 

(2)    the purchase of fractional interests in shares of the Company’s capital stock pursuant to the
conversion or exchange provisions of such capital stock or the security being converted or exchanged; 

(3)    dividends, payments or distributions payable in shares of capital stock; 

(4)    redemptions, purchases or other acquisitions of shares of capital stock in connection with any
employment contract, incentive plan, benefit plan or other similar arrangement of the Company or any of its Subsidiaries or in connection with a dividend reinvestment or stock purchase plan; or 

(5)    any declaration of a dividend in connection with implementation of any stockholders’ rights
plan, or the issuance of rights, stock or other property under any such plan, or the redemption, repurchase or other acquisition of any such rights pursuant thereto. 

SECTION 2.16    The provisions of Article Seventeen of the Indenture, as amended and supplemented by this Section 2.16, shall apply
to the Debentures, and the term “Senior Indebtedness”, as used in such Article Seventeen, shall mean Senior Indebtedness of the Company. 

  
 16 

 The first and second paragraphs of Section 1702 of the Indenture are hereby amended and
restated as follows: 
 SECTION 1702. Distribution on Dissolution, Liquidation and Reorganization; Subrogation of Securities.
Upon any payment or distribution of assets of the Company to creditors upon any dissolution, winding up, liquidation or reorganization of the Company, whether in bankruptcy, insolvency, reorganization or receivership proceedings or upon an
assignment for the benefit of creditors or any other marshalling of the assets and liabilities of the Company or any bankruptcy, insolvency or similar proceedings of the Company (subject to the power of a court of competent jurisdiction to make
other equitable provision reflecting the rights conferred in this Indenture upon the Senior Indebtedness and the holders thereof with respect to the Subordinated Securities and the holders thereof by a lawful plan of reorganization under applicable
bankruptcy law): 
 (a)    the holders of all Senior Indebtedness shall be entitled to receive payment in
full of all amounts due or to become due on or in respect of all Senior Indebtedness before the Holders of the Subordinated Securities are entitled to receive or retain any payment or distribution upon such Subordinated Securities; and 

(b)    any payment or distribution of assets of the Company of any kind or character, whether in cash,
property or securities, to which the Holders of the Subordinated Securities or the Trustee would be entitled except for the provisions of this Article Seventeen shall be paid by the liquidating trustee or agent or other person making such payment or
distribution, whether a trustee in bankruptcy, a receiver or liquidating trustee or otherwise, directly to the holders of Senior Indebtedness or their representative or representatives or to the trustee or trustees under any indenture under which
any instruments evidencing any of such Senior Indebtedness may have been issued, ratably according to the aggregate amounts remaining unpaid on account of the principal of (and premium, if any) and interest on the Senior Indebtedness held or
represented by each, to the extent necessary to make payment in full of all Senior Indebtedness remaining unpaid, after giving effect to any concurrent payment or distribution to the holders of such Senior Indebtedness; and 

(c)    in the event that, notwithstanding the foregoing, any payment or distribution of assets of the
Company of any kind or character, whether in cash, property or securities, shall be received by the Trustee or the Holders of the Subordinated Securities before all Senior Indebtedness is paid in full, such payment or distribution shall be paid
over, upon written notice to a Responsible Officer of the Trustee, to the holder of such Senior Indebtedness or their representative or representatives or to the trustee or trustees under any indenture under which any instrument evidencing any of
such Senior Indebtedness may have been issued, ratably as aforesaid, for application to payment of all Senior Indebtedness remaining unpaid until all such Senior Indebtedness shall have been paid in full, after giving effect to any concurrent
payment or distribution to the holders of such Senior Indebtedness. 
 Subject to the prior payment in full of all Senior
Indebtedness, the rights of Holders of Subordinated Securities shall be subrogated to the rights of the holders of 

  
 17 

 
Senior Indebtedness (to the extent that distributions otherwise payable to such Holders have been applied to the payment of Senior Indebtedness) to receive payments and distributions of the
Company applicable to Senior Indebtedness until all amounts owing on the Subordinated Securities shall be paid in full and no such payments or distributions to the Holders of the Subordinated Securities otherwise distributable to the holders of
Senior Indebtedness shall, as between the Company, its creditors other than the holders of Senior Indebtedness, and the Holders of the Subordinated Securities be deemed to be a payment by the Company to or on account of the Subordinated Securities.
It is understood that the provisions of this Article Seventeen are and are intended solely for the purpose of defining the relative rights of the Holders of Subordinated Securities, on the one hand, and the holders of Senior Indebtedness, on the
other hand. Nothing contained in this Article Seventeen or elsewhere in this Indenture or in the Subordinated Securities is intended to or shall impair, as between the Company, its creditors other than the holders of Senior Indebtedness, and the
Holders of the Subordinated Securities, the obligation of the Company, which is unconditional and absolute, to pay to the Holders of the Subordinated Securities the principal of (and premium, if any) and interest, if any, on the Subordinated
Securities as and when the same shall become due and payable in accordance with their terms, or to affect the relative rights of the Holders of the Subordinated Securities and creditors of the Company other than the holders of Senior Indebtedness,
nor shall anything herein or in the Subordinated Securities prevent the Trustee or the Holder of any Subordinated Security from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights,
if any, under this Article Seventeen of the holders of Senior Indebtedness in respect of cash, property or securities of the Company received upon the exercise of any such remedy. Upon any payment or distribution of assets of the Company referred to
in this Article Seventeen, the Trustee, subject to the provisions of Section 602, shall be entitled to rely upon a certificate of the liquidating trustee or agent or other person making any distribution to the Trustee for the purpose of
ascertaining the Persons entitled to participate in such distribution, the holders of Senior Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereof and all other
facts pertinent thereto or to this Article Seventeen. 
 Section 1703 of the Indenture is hereby amended and restated as follows: 

SECTION 1703. No Payment on Subordinated Securities in Event of Default on Senior Indebtedness. No payment of principal of
(including redemption payments, if any), premium, if any, on or interest on the Subordinated Securities may be made if (a) any Senior Indebtedness is not paid when due and any applicable grace period with respect to such default has ended with
such default not being cured or waived or otherwise ceasing to exist, or (b) the maturity of any Senior Indebtedness has been accelerated because of a default, or (c) notice has been given of the exercise of an option to require repayment,
mandatory payment or prepayment or otherwise of the Senior Indebtedness.

 SECTION 2.17    Sections 801, 802, 1009 and 1010 of the Indenture are hereby deleted and
replaced by “SECTION 801. [Reserved.]”, “SECTION 802. [Reserved.]”, “SECTION 1009. [Reserved.]” and “SECTION 1010. [Reserved.]”, respectively. 

SECTION 2.18    The following Section 1012 is hereby added to the Indenture: 

SECTION 1012. Agreement by Holders to Certain Tax Treatment. Each Holder of the Debentures shall, by accepting the Debentures
or a beneficial interest therein, be deemed to have agreed that the Holder intends that the Debentures constitute indebtedness and shall treat the Debentures as indebtedness for United States federal, state and local tax purposes. 

SECTION 3.     THE LAWS OF THE STATE OF NEW YORK SHALL GOVERN THIS TWENTIETH SUPPLEMENTAL INDENTURE. 

SECTION 4.     This Twentieth Supplemental Indenture may be executed in any number of counterparts, each of which when so executed shall
be deemed to be an original, but such counterparts shall together constitute but one and the same instrument. 
 SECTION 5.     Except
as herein amended with respect to the Debentures, all applicable terms, conditions and provisions of the Indenture, as supplemented, shall continue in full force and effect and shall remain binding and enforceable in accordance with their respective
terms. 
 SECTION 6.    The Trustee makes no representations as to the validity or sufficiency of this Supplemental Indenture. The
recitals and statements herein are deemed to be those of the Company and not of the Trustee. The Trustee shall not be responsible for monitoring whether any Tax Event, Rating Agency Event or Change of Control Event as contemplated by Sections 1101A,
1101B and 1101C of the Indenture has occurred.

 EXHIBIT A TO TWENTIETH SUPPLEMENTAL INDENTURE 

Each Global Security shall bear the following legend: Unless this certificate is presented by an authorized representative of The Depository
Trust Company, a New York corporation (“DTC”), to the Company (as defined below) or its agent for registration of transfer, exchange or payment, and any certificate issued is registered in the name of Cede & Co. or such other
name as is requested by an authorized representative of DTC (and any payment is made to Cede & Co. or to such other entity as is requested by an authorized representative of DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR
OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered owner hereof, Cede & Co., has an interest herein. 
 Any
Global Security issued hereunder shall bear a legend in substantially the following form: This Security is a Global Security within the meaning of the Indenture hereinafter referred to and is registered in the name of the Depositary or a nominee of
the Depositary. This Security is exchangeable for Securities registered in the name of a person other than the Depositary or its nominee only in the limited circumstances described in the Indenture, and may not be transferred except as a whole by
the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such a successor Depositary.

	No.     	  	$             
		
		  	CUSIP: 92553P BD3

 Viacom Inc., a Delaware corporation (herein called 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 February 28, 2057 at the
office or agency of the Company referred to below, and to pay interest thereon (i) in arrears on August 28, 2017 and semiannually thereafter, on February 28 and August 28 in each year, from February 28, 2017, or from the
most recent Interest Payment Date to which interest has been paid or duly provided for, initially at the rate of 5.875% per annum, to, but excluding, February 28, 2022, and (ii) in arrears on May 28, 2022 and quarterly thereafter, on
February 28, May 28, August 28 and November 28 in each year, from, and including, February 28, 2022, or from the most recent Interest Payment Date to which interest has been paid or duly provided for, to, but excluding
February 28, 2057, at an annual rate equal to Three-Month LIBOR plus 3.895%, reset quarterly, until the principal hereof is paid or duly provided for. The rate of interest payable during the Floating-Rate Period is subject to the maximum
interest rate permitted by the law of the State of New York or other applicable state law, as such law may be modified by United States law of general application. In no event shall the rate of interest payable on the Debentures during the
Floating-Rate Period be less than 0.0%. 
 The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date
will, as provided in such 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, during the Fixed-Rate Period, shall be the February 13 or August 13, as the case may be, next preceding such Interest Payment Date, and, during the Floating-Rate Period, shall be the fifteenth calendar day, whether or not a LIBOR
Business Day, that precedes the applicable Interest Payment Date. 
 The Company may, at its sole option, on one or more occasions, defer
payment of all or part of the current and accrued interest otherwise due on this Security for up to five (5) consecutive years per deferral by extending the interest payment period pursuant to Section 1001A of the Indenture. 

Subject to the Company’s right to optionally defer interest payments pursuant to Section 1001A of the Indenture, 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, shall 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 the Holder of this Security not less than 10 days prior to such Special Record Date,
or may be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities may be listed, and upon such notice as may be required by such exchange, all as more fully provided in
said 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 in immediately available funds by transfer to an account maintained by the payee located in the United States.

 The statements set forth in the restrictive legends above are an integral part of the terms of this Security and by acceptance hereof
each holder of this Security agrees to be subject to and bound by the terms and provisions set forth in such legend. 
 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 an indenture dated as of April 12, 2006 between the
Company and The Bank of New York Mellon, as trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), as supplemented from time to time and as further supplemented by the Twentieth Supplemental
Indenture dated as of February 28, 2017 between the Company and the Trustee (as so supplemented, the “Indenture”), to which Indenture and all indentures supplemental thereto 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 5.875% Fixed-to-Floating Rate Junior Subordinated Debentures due 2057, initially limited in aggregate principal amount to $650,000,000.
This Security is a global Security representing $[        ] of the Securities, which are unsecured and rank junior in right of payment to all of the Company’s Senior Indebtedness, whether existing on the
date of issuance of this Security or from time to time incurred, created, assumed or existing after the date of issuance of this Security. All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in
the Indenture. 
 INCLUDE IF SECURITY IS A GLOBAL SECURITY: This Security is a “book-entry” Security and is being registered in
the name of Cede & Co. as nominee of The Depository Trust Company (“DTC”), a clearing agency. Subject to the terms of the Indenture, this Security will be held by a clearing agency or its nominee, and beneficial interest will be
held by beneficial owners through the book-entry facilities of such clearing agency or its nominee in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. 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, the final payment on this Security will be made after due
notice by the Trustee of the pendency of such payment and only upon presentation and surrender of this Security at its principal corporate trust office or such other offices or agencies appointed by the Trustee for that purpose and such other
locations provided in the Indenture. 

  
 A-3 

 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.

 Viacom Inc., a Delaware corporation (herein called 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 February 28, 2057 at the

February 28, May 28, August 28 and November 28 in each year, from, and including, February 28, 2027, or from the most recent Interest Payment Date to which interest has been paid or duly provided for, to, but excluding

payment of all or part of the current and accrued interest otherwise due on this Security for up to five (5) consecutive years per deferral by extending the interest payment period pursuant to Section 1001A of the Indenture. 

Subject to the Company’s right to optionally defer interest payments pursuant to Section 1001A of the Indenture, 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, shall 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 the Holder of this Security not less than 10 days prior to such Special Record Date,
or may be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities may be listed, and upon such notice as may be required by such exchange, all as more fully provided in

 2 

 (iii)    authority to construe and interpret the terms of the Bonus
Plan; 
 (iv)    authority to prescribe forms and procedures for purposes of Bonus Plan participation and
distribution of Bonus Awards; and 
 (v)    authority to adopt rules, regulations and bylaws and to take such
actions as it deems necessary or desirable for the proper administration of the Bonus Plan. 
 (b)    Any
rule or decision by the Committee that is not inconsistent with the provisions of the Bonus Plan or the 2015 Plan shall be conclusive and binding on all persons, and shall be given the maximum deference permitted by law. 

4.    Eligibility. Participation in the Bonus Plan is at the discretion of the Committee. Officers of the Company who are regularly
employed (full or part time) during the Performance Period and who are subject to Section 16 of the Securities Exchange Act of 1934, are eligible to participate in the Bonus Plan. If an officer is hired after the beginning of the Performance
Period, the Committee shall have the discretion to determine whether such officer should be eligible to participate in the Bonus Plan. If the Participant’s Bonus Plan target percent changes during the Performance Period, the officer’s
Target Bonus Award will be pro-rated based on those adjusted figures as follows: the Target Bonus Award will be based on the number of days in the Performance Period with the former Bonus Plan annual bonus
target percent and the number of days in the Performance Period with the new Bonus Plan annual target percent. A Participant must be employed through the payment date to earn any award under this Bonus Plan; if the Participant’s employment
terminates before the payment date of any Bonus Award, the Participant will not be eligible to receive a Bonus Award, or any portion of a Bonus Award, except as provided in an applicable severance plan or in an individual employment or retention
agreement with such Participant. If a Participant is on a leave of absence for a portion of the Performance Period, the Participant will be eligible for a Bonus Award under the Bonus Plan based on actual salary earned during the Performance Period
(exclusive of any salary replacement benefits paid during the leave via insurance). 
 5.    Bonus Awards. 

(a)    Bonus Plan Components. The Bonus Plan components are: (i) the Performance Goals;
(ii) the Target Bonus Award; (iii) the Maximum Bonus Award; and (iv) the Bonus Award. 

(b)    Performance Goal Determination. On the Target Determination Date, the Committee, in its sole
discretion, shall establish the Performance Goals for each Participant for the Performance Period. Such Performance Goals shall be set forth in writing on or prior to the applicable Target Determination Cutoff Date, and the achievement of such
Performance Goals shall be substantially uncertain at such time. 
 (c)    Target Bonus Award. On the
Target Determination Date, the Committee, in its sole discretion, shall designate a Target Bonus Award for each Participant. Each Participant’s Target Bonus Award shall be set forth in writing on or prior to the Target Determination Cutoff
Date. The Participant’s Bonus Award is calculated, in part (as further described below), by reference to his or her Target Bonus Award. 

  
 3 

 (d)    Maximum Bonus Award. Subject to Section 2(e) above, the
Maximum Bonus Award that may be earned by a Participant is 150 percent of the Participant’s Target Bonus Award. 

(e)    Payout Formula. On the Target Determination Date, the Committee, in its sole discretion, shall
establish the Payout Formula for purposes of determining the Bonus Award that may be earned by each Participant. Each Payout Formula (a) shall be set forth in writing on or prior to the Target Determination Cutoff Date, (b) shall provide
for the payment of a Participant’s Bonus Award if the Performance Goals for the Performance Period are achieved, and (c) may provide for a Bonus Award payment greater than or less than the Participant’s Target Bonus Award (i.e., a
Maximum Bonus Award and a threshold award), depending upon the extent to which the Performance Goals are achieved. Notwithstanding the preceding, in no event shall a Participant’s Bonus Award for any Performance Period exceed the Maximum Bonus
Award. 
 (f)    Determination of the Bonus Award. On the Payout Determination Date, the
Committee shall determine and certify in writing (which may be by approval of the minutes in which the certification was made) the extent to which the Performance Goals applicable to each Participant for the Performance Period were achieved or
exceeded. The Bonus Award for each Participant shall be determined by applying the Payout Formula to the level of actual performance that has been certified by the Committee. Notwithstanding any contrary provision of the Bonus Plan, the Committee,
in its sole discretion, may eliminate or reduce the Bonus Award payable to any Participant below that which otherwise would be payable under the Payout Formula in its discretion. 

6.    Bonus Award Payment. 

(a)    Right to Receive Payment. Each Bonus Award under the Bonus Plan shall be paid
solely from the general assets of the Company. Nothing in the Bonus Plan shall be construed to create a trust or to establish or evidence any Participant’s claim of any right to payment of a Bonus Award other than as an unsecured general
creditor with respect to any payment to which he or she may be entitled. 
 (b)    Form of
Payment of Bonus Awards. Except as otherwise determined by the Committee, subject to Section 4, the Company shall distribute a Participant’s Bonus Award to the Participant in the form of cash and/or shares of Common
Stock, as determined by the Committee, in its sole discretion, on the Payout Determination Date. Subject to Section 6(d), a Participant’s Bonus Award shall be paid to the Participant as soon as is practicable following the Payout Determination
Date for the Performance Period, but in no event later than the 15th day of the third calendar month after the end of the calendar year in which the Participant’s Bonus Award is no longer subject to a substantial risk of forfeiture, within the
meaning of Treasury Regulation Section 1.409A-1(d). Payments under this Bonus Plan shall be made in a manner that complies with Treasury Regulation Section
1.409A-1(b)(4) and this Bonus Plan shall be construed in accordance with such provision. 

  
 4 

 (c)    Tax Withholding. The Company will withhold from any
payments under the Bonus Plan and from any other amounts payable to a Participant by the Company any amount required to satisfy the income and employment tax withholding obligations arising under applicable federal and state laws in respect of a
Bonus Award. Without limiting the forgoing, with respect to any portion of a Bonus Award paid in shares of Common Stock, the Company may, in its sole discretion, satisfy all or any portion of its tax withholding obligations by (i) causing a
Participant to tender a cash payment, (ii) permitting a Participant to enter into a “same day sale” commitment, if applicable, with a broker-dealer whereby the Participant irrevocably elects to sell a portion of the shares of Common
Stock to satisfy the Company’s withholding obligation and whereby the broker-dealer irrevocably commits to forward the proceeds necessary to satisfy the Company’s withholding obligation directly to the Company, or (iii) withholding
from any shares of Common Stock otherwise issuable to a Participant a number of whole shares having a fair market value as of the date of payment not in excess of the minimum amount of tax required to be withheld by the Company by law. The Company
may require the Participant to satisfy any remaining amount of the tax withholding obligations by tendering a cash payment. Each Participant is encouraged to contact his or her personal legal or tax advisors with respect to the benefits provided by
the Bonus Plan. Neither the Company nor any of its employees, directors, officers or agents are authorized to provide any tax advice to Participants with respect to the benefits provided under the Bonus Plan. 

(d)    Deferral. The Committee may defer payment of Bonus Awards payable in cash pursuant
to Section 6(b), or any portion thereof, to Participants in accordance with Section 409A of the Code as the Committee, in its sole discretion, determines to be necessary or desirable to preserve the deductibility of such amounts under
Section 162(m). In addition, the Committee, in its sole discretion, may permit a Participant to defer receipt of the payment of cash that would otherwise be delivered to a Participant under the Bonus Plan. Any such deferral elections shall
comply with the requirements of Section 409A of the Code, and shall be subject to such rules and procedures as shall be determined by the Committee in its sole discretion. 

7.    Amendment and Termination of the Bonus Plan. The Committee may amend, modify, suspend or terminate
the Bonus Plan, in whole or in part, at any time, including adopting amendments deemed necessary or desirable to correct any defect or to supply omitted data or to reconcile any inconsistency in the Bonus Plan or in any Bonus Award granted
hereunder; provided, however, that no amendment, alteration, suspension or discontinuation shall be made that would (i) increase the amount of compensation payable pursuant to such Bonus Award, (ii) cause compensation that is, or
may become, payable hereunder to fail to qualify as Performance-Based Compensation, or (iii) change the payment dates of any shares of Common Stock if such change would fail to comply with the requirements of Section 409A of the Code. To the
extent necessary or advisable under applicable law, including Section 162(m), Bonus Plan amendments shall be subject to stockholder approval. At no time before the actual distribution of funds to Participants under the Bonus Plan shall any
Participant accrue any vested interest or right whatsoever under the Bonus Plan except as otherwise stated in the Bonus Plan.

 8.    Bifurcation of the Bonus Plan. It is the intent of the
Company that the Bonus Plan, and all payments made hereunder, satisfy and be interpreted in a manner that, in the case of Participants whose compensation is subject to the limitations on deductibility of compensation provided under Section 162(m)
and whose payment hereunder is intended to qualify as Performance-Based Compensation, qualify as Performance-Based Compensation. Any provision, application or interpretation of the Bonus Plan inconsistent with this intent to satisfy the requirements
of Section 162(m) shall be disregarded. However, notwithstanding anything to the contrary in the Bonus Plan, the provisions of the Bonus Plan may at any time be bifurcated by the Board or the Committee in any manner so that certain provisions of the
Bonus Plan or any payment intended (or required) to satisfy the applicable requirements of Section 162(m) are applicable only to persons whose compensation is subject to the limitations on deductibility of compensation provided under Section 162(m)
and whose payment hereunder is intended to qualify as Performance-Based Compensation. 
 9.    No Guarantee of Employment.
The Bonus Plan is intended to provide a financial incentive to Participants and is not intended to confer any rights to continued employment upon Participants whose employment will remain at-will and subject
to termination by either the Company or Participant at any time, with or without cause or notice. 
 10.    Recovery. Any
amounts paid (or shares of Common Stock granted) under this Bonus Plan will be subject to recoupment in accordance with any clawback policy that the Company is required to adopt pursuant to the listing standards of any national securities exchange
or association on which the Company’s securities are listed or as is otherwise required by the Dodd-Frank Wall Street Reform and Consumer Protection Act or other applicable law. No recovery of compensation under such a clawback policy will be
an event giving rise to a right to resign for “good reason” or “constructive termination” (or similar term) under any plan of or agreement with the Company.
