 Section 1.04.
Acts of Holders. 
 (a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided
by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agents duly appointed in writing; and, except as herein otherwise
expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose
of this Indenture and (subject to Section 6.01) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section. 
 (b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer
authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other
manner which the Trustee deems sufficient. 
 (c) The ownership of Registered Securities shall be proved by the Security
Register. 
 (d) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any
Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by
the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Security. 

  
 10 

 (e) If the Company shall solicit from the Holders any request, demand, authorization,
direction, notice, consent, waiver or other Act, the Company may, at its option, by or pursuant to a Board Resolution, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction,
notice, consent, waiver or other Act, but the Company shall have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record
date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of Outstanding Securities have authorized or agreed or
consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Outstanding Securities shall be computed as of such record date; provided that no such authorization, agreement or consent by
the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date. 

Section 1.05. Notices, Etc., to Trustee and Company. Any request, demand, authorization, direction, notice, consent, waiver or Act
of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with, 

(a) the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in
writing to or with the Trustee and received by the Trustee at its Corporate Trust Office, Attention: Corporate Trust Services, or 
 (b) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the
Company addressed to it at the address of its principal office specified in the first paragraph of this Indenture, attention: Secretary, or at any other address previously furnished in writing to the Trustee by the Company. 

Section 1.06. Notice to Holders; Waiver. Where this Indenture or any Security provides for notice to Holders of any event, such
notice shall be deemed sufficiently given (unless otherwise herein or in such Security expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at his address as it appears in the Security
Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice
so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders or the validity of the proceedings to which such notice relates. Where this Indenture or any Security provides for notice in any manner,
such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice 

  
 11 

 
by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. 

In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice
by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. 
 Any request, demand, authorization, direction, notice, consent or waiver required or permitted under this Indenture shall be in the English language, except that any published notice may be in an official
language of the country of publication. 
 Section 1.07. Conflict with Trust Indenture Act. If any provision hereof
limits, qualifies or conflicts with another provision hereof which is required to be included in this Indenture by any of the provisions of the Trust Indenture Act, such required provision shall control. If any provision of this Indenture modifies
or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or shall be excluded, as the case may be. 

Section 1.08. Effect of Headings and Table of Contents. The Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof. 
 Section 1.09. Successors and Assigns. All covenants and
agreements in this Indenture by the Company shall bind its successors and assigns, whether so expressed or not. 
 Section
1.10. Separability Clause. In case any provision in this Indenture or in the Securities shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or
impaired thereby. 
 Section 1.11. Benefits of Indenture. Nothing in this Indenture or in the Securities, express or
implied, shall give to any Person, other than the parties hereto and their successors hereunder and the Holders, any benefit or any legal or equitable right, remedy or claim under this Indenture. 

Section 1.12. Governing Law. This Indenture and the Securities shall be governed by and construed in accordance with the laws
(other than the choice of law provisions) of the State of New York. 
 Section 1.13. Legal Holidays. In any case where
any Interest Payment Date, Redemption Date or Stated Maturity of any Security shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or of the Securities) payment of interest or principal
(and premium, if any) need not be made at such Place of Payment on such date, but may be made 

  
 12 

 
on the next succeeding Business Day or on such other day as may be set out in the Officer’s Certificate pursuant to Section 3.01 at such Place of Payment with the same force and effect
as if made on the Interest Payment Date or Redemption Date, or at the Stated Maturity, provided that no interest shall accrue for the period from and after such Interest Payment Date, Redemption Date or Stated Maturity, as the case may be.

 Section 1.14. No Recourse Against Others. A director, officer, employee or stockholder, as such, of the Company shall
not have any liability for any obligations of the Company under the Securities or this Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Security holder, by accepting a Security, waives and
releases all such liability. Such waivers and releases are part of the consideration for the issuance of the Securities.

accepted financial practice) of less than             % per annum.) 
 (The sinking fund for this series provides for the redemption in each year beginning with the year              and ending with the year
             of (not less than) $             (“mandatory sinking fund”) and not more than

  
 16 

 
$             aggregate principal amount of Securities of this series.) (Securities of this series acquired or redeemed by the

described in the Indenture. In addition, the Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of
each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also
contains provisions permitting the Holders of a majority in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain
provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall bind such Holder and all future Holders of this Security and of any Security issued
upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. 

  
 17 

 No reference herein to the Indenture and no provision of this Security or of the Indenture
shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, and premium, if any, and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly
endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of
this series, of authorized denominations and for the same Stated Maturity and aggregate principal amount, will be issued to the designated transferee or transferees. 
 The Securities of this series are issuable only in registered form without coupons in denominations of ($1,000) and any integral multiple thereof. As provided in the Indenture and subject to certain
limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same. 

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection therewith. 
 Prior to due presentment of this
Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue,

certain limitations on the ability of the Company to, among other things, merge or consolidate with any other Person or sell, assign, transfer or lease all or substantially all of its properties or assets (If other covenants are applicable pursuant

Indenture. 
 A director, officer, employee or stockholder, as such, of the Company shall not have any liability for any
obligations of the Company under this Security or the Indenture or for any claim based on, in respect of or by reason of, such obligations or their creation. Each Holder, by accepting a Security, waives and

  
 18 

 
releases all such liability. The waiver and release are part of the consideration for the issuance of this Security.

 Section 2.05. Securities in Global Form. If Securities of a series are issuable in global
form, as contemplated by Section 3.01, then, notwithstanding the provisions of Section 3.02, any such Security shall represent such of the Outstanding Securities of such series as shall be specified therein and may provide that it shall
represent the aggregate amount of Outstanding Securities from time to time endorsed thereon and that the aggregate amount of Outstanding Securities represented thereby may from time to time be reduced to reflect exchanges. Any endorsement of a
Security in global form to reflect the amount, or any increase or decrease in the amount, of Outstanding Securities represented thereby shall be made in such manner and upon instructions given by such Person or Persons as shall be specified therein
or in the Company Order to be delivered to the Trustee pursuant to Section 3.03 or Section 3.04. Subject to the provisions of Section 3.03 and, if applicable, Section 3.04, the Trustee shall deliver and redeliver any Security in
permanent global form in the manner and upon instructions given by the Person or Persons specified therein or in the applicable Company Order. If a Company Order pursuant to Section 3.03 or 3.04 has been, or simultaneously is, delivered, any
instructions by the Company with respect to endorsement or delivery or redelivery of a Security in global form shall be in writing but need not comply with Section 1.02 and need not be accompanied by an Opinion of Counsel. 

The provisions of Section 3.09 shall apply to any Security represented by a Security in global form if such Security was never
issued and sold by the Company and the Company delivers to the Trustee the Security in global form together with written instructions (which need not comply with Section 1.02 and need not be accompanied by an Opinion of Counsel) with regard to
the reduction in the principal amount of Securities represented thereby. 
 Notwithstanding the provisions of Sections 2.01 and
3.07, unless otherwise specified as contemplated by Section 3.01, payment of principal of, premium, if any, and interest on any Security in permanent global form shall be made to the Person or Persons specified therein. 

Notwithstanding the provisions of Section 3.08 and except as provided in the preceding paragraph, the Company, the Trustee and any
agent of the Company and the Trustee shall treat a Person as the Holder of such principal amount of 

  
 20 

 
Outstanding Securities represented by a permanent global Security as shall be specified in a written statement of the Holder of such permanent global Security. 

Section 2.06. CUSIP Number. The Company in issuing Securities of any series may use a “CUSIP” number, and, if so, the
Trustee may use the CUSIP number in notices of redemption or exchange as a convenience to Holders of such series; provided, that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP number printed
on the notice or on the Securities of such series, and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The
Company will promptly notify the Trustee of any change in the CUSIP number of any series of Securities. 
 Section 2.07. Form
of Legend for the Securities in Global Form. Any Security in global form authenticated and delivered hereunder shall bear a legend in substantially the following form: 
 “This Security is in global form within the meaning of the Indenture hereinafter referred to and is registered in the name of a Common Depositary or a U.S. Depositary. Unless and until it is
exchanged in whole or in part for Securities in certificated form, this Security may not be transferred except as a whole by the Common Depositary or a U.S. Depositary or by a nominee of the Common Depositary or a nominee of the U.S. Depositary as
the case may be.” 
 ARTICLE 3

(f) the place or places where the principal of (and premium, if any) and interest on Securities of the series shall be payable and where

(m) if either or both of Section 13.02 and Section 13.03 shall be inapplicable to the Securities of the series (provided that
if no such inapplicability shall be specified, then both Section 13.02 and Section 13.03 shall be applicable to the Securities of the series);

 (u) any other terms of the series (which terms shall not be
inconsistent with the provisions of this Indenture). 
 All Securities of any one series shall be substantially identical except
as to denomination and except as may otherwise be provided in or pursuant to such Board Resolution and set forth in such Officer’s Certificate or in any such indenture supplemental hereto. 

If any of the terms of the series are established by action taken pursuant to a Board Resolution, a copy of an appropriate record of such
action shall be certified by the Secretary or an Assistant Secretary of the Company and delivered 

  
 23 

 
to the Trustee at or prior to the delivery of the Officer’s Certificate setting forth, or providing the manner for determining, the terms of the Securities of such series. 

Section 3.02. Denominations. The Securities of each series shall be issuable in registered form without coupons in such
denominations as shall be specified as contemplated by Section 3.01. In the absence of any such provisions with respect to the Securities of any series, the Securities of such series shall be issuable in denominations of $1,000 and any integral
multiple thereof. 
 Section 3.03. Execution, Authentication, Delivery and Dating. The Securities shall be executed on
behalf of the Company by its Chairman of the Board, its Chief Executive Officer, its President, any Vice President or the Treasurer, under its corporate seal reproduced thereon attested by its Secretary or one of its Assistant Secretaries. The
signature of any of these officers on the Securities may be manual or facsimile. The seal of the Company may be in the form of a facsimile thereof and may be impressed, affixed, imprinted or otherwise reproduced on the Securities. Typographical and
other minor errors or defects in any such reproduction of the seal or any such signature shall not affect the validity or enforceability of any security that has been duly authenticated and delivered by the Trustee. 

Securities bearing the manual or facsimile signatures of individuals who were at any time the proper Officers of the Company shall bind
the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities. 

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series
executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with the Company Order shall authenticate and make such Securities
available for delivery. If the form or terms of the Securities of the series have been established in or pursuant to one or more Board Resolutions as permitted by Sections 2.01 and 3.01, in authenticating such Securities, and accepting the
additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Sections 315(a) through (d) of the Trust Indenture Act) shall be fully protected in relying upon, an
Opinion of Counsel stating, 
 (a) if the form of such Securities has been established by or pursuant to Board Resolution as
permitted by Section 2.01, that such form has been established in conformity with the provisions of this Indenture; 
 (b)
if the terms of such Securities have been established by or pursuant to Board Resolution as permitted by Section 3.01, that such terms have been established in conformity with the provisions of this Indenture; 

  
 24 

 (c) that such Securities, when authenticated and delivered by the Trustee and issued by the
Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company, enforceable in accordance with their terms, except to the extent enforceability may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium and other similar laws affecting the enforcement of creditors’ rights generally and by the effect of general principles of equity (regardless of whether enforceability is
considered in a proceeding in equity or at law); and 
 (d) that no consent, approval, authorization, order, registration or
qualification of or with any court or any governmental agency or body having jurisdiction over the Company is required for the execution and delivery of such Securities by the Company, except such as have been obtained (except that no opinion need
be expressed as to state securities or Blue Sky laws). 
 If such form or terms have been so established, the Trustee shall not
be required to authenticate such Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not
reasonably acceptable to the Trustee, or in the written opinion of counsel to the Trustee (which counsel may be an employee of the Trustee) such authentication may not lawfully be made or would involve the Trustee in personal liability. 

Notwithstanding the provisions of Section 3.01 and of the immediately preceding paragraph, if all Securities of a series are not to
be originally issued at one time, it shall not be necessary to deliver the Officer’s Certificate otherwise required pursuant to Section 3.01 or the Company Order and Opinion of Counsel otherwise required pursuant to the immediately
preceding paragraph at or prior to the time of authentication of each security of such series if such documents are delivered at or prior to the authentication upon original issuance of the first security of such series to be issued. 

If the Company shall establish pursuant to Section 3.01 that the Securities of a series are to be issued in the form of one or more
global Securities, then the Company shall execute and the Trustee shall, in accordance with this Section and the Company Order with respect to the authentication and delivery of such series, authenticate and deliver one or more global Securities
that (i) shall be in an aggregate amount equal to the aggregate principal amount specified in such Company Order, (ii) shall be registered in the name of the Common Depositary or U.S. Depositary, as the case may be, therefor or its
nominee, and (iii) shall be made available for delivery by the Trustee to such depositary or pursuant to such depositary’s instruction. 
 Each depositary designated pursuant to Section 3.01 must, at the time of its designation and at all times while it serves as depositary, be a clearing agency registered under the Exchange Act and any
other applicable statute or regulation. 

  
 25 

 Unless otherwise provided for in the form of security, each security shall be dated the date
of its authentication. 
 No security shall be entitled to any benefit under this Indenture or be valid or obligatory for any
purpose unless there appears on such security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any security shall be conclusive evidence, and the
only evidence, that such security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. 
 Section 3.04. Temporary Securities. Pending the preparation of definitive Securities of any series, the Company may execute a Company Order and, upon receipt thereof, the Trustee shall authenticate
and make available for delivery, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are
issued and with such appropriate insertions, omissions, substitutions and other variations as the proper Officers executing such Securities may determine, as evidenced by their execution of such Securities. 

In the case of Securities of any series, such temporary Securities may be in global form, representing all or a portion of the
Outstanding Securities of such series. 
 Except in the case of temporary Securities in global form (which shall be exchanged in
accordance with the provisions of Section 3.05), if temporary Securities of any series are issued, the Company will cause definitive Securities of that series to be prepared without unreasonable delay. After the preparation of definitive
Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at the office or agency of the Company in a Place of Payment
for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series, the Company shall execute and the Trustee shall authenticate and make available for delivery in exchange therefor a
like principal amount of definitive Securities of the same series of authorized denominations and of like tenor. Until so exchanged, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture
as definitive Securities of such series. 
 If temporary Securities of any series are issued in global form, any such temporary
global Security shall, unless otherwise provided therein, be delivered to the office of a depositary or common depositary (the “Common Depositary”) for credit to the respective accounts of the beneficial owners of such Securities
(or to such other accounts as they may direct). 

  
 26 

 Section 3.05. Registration, Registration of Transfer and Exchange. The Company shall
cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency of the Company in a Place of Payment being herein sometimes collectively referred to as the
“Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of registration of transfers of Securities. The Trustee is hereby appointed
“Security Registrar” for the purpose of registering Securities and transfers of Securities as herein provided. 

Upon surrender for registration of transfer of any security of any series at the office or agency of the Company in Place of Payment for
that series, the Company shall execute, and the Trustee shall authenticate and make available for delivery, in the name of the designated transferee or transferees, one or more new Securities of the same series, of any authorized denominations and
of a like aggregate principal amount and Stated Maturity. 
 At the option of the Holder, Securities of any series may be
exchanged for other Securities of the same series, of any authorized denominations and of a like aggregate principal amount and Stated Maturity, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are
so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and make available for delivery, the Securities which the Holder making the exchange is entitled to receive. 

Notwithstanding the foregoing, except as otherwise specified as contemplated by Section 3.01, any permanent global security shall be
exchangeable only as provided in this paragraph. If the beneficial owners of interests in a permanent global security are entitled to exchange such interests for Securities of such series and of like tenor and principal amount of another authorized
form and denomination, as specified and as subject to the conditions contemplated by Section 3.01, then without unnecessary delay but in any event not later than the earliest date on which such interests may be so exchanged, the Company shall
deliver to the Trustee definitive Securities of that series in aggregate principal amount equal to the principal amount of such permanent global security, executed by the Company. On or after the earliest date on which such interests may be so
exchanged, such permanent global Securities shall be surrendered from time to time by the Common Depositary or the U.S. Depositary, as the case may be, and in accordance with instructions given to the Trustee and the Common Depositary or the U.S.
Depositary, as the case may be (which instructions shall be in writing but need not comply with Section 1.02 or be accompanied by an Opinion of Counsel), as shall be specified in the Company Order with respect thereto to the Trustee, as the
Company’s agent for such purpose, to be exchanged, in whole or in part, for definitive Securities of the same series without charge. The Trustee shall authenticate and make available for delivery, in exchange for each portion of such
surrendered permanent global security, a like aggregate principal amount of definitive Securities of the same 

  
 27 

 
series of authorized denominations and of like tenor as the portion of such permanent global security to be exchanged which shall be in the form of the Securities of such series; provided,
however, that no such exchanges may occur during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of Securities of that series selected for redemption under Section 11.03 and ending
at the close of business on the day of such mailing. Promptly following any such exchange in part, such permanent global Security shall be returned by the Trustee to the Common Depositary or the U.S. Depositary, as the case may be, or such other
Common Depositary or U.S. Depositary referred to above in accordance with the written instructions of the Company referred to above. If a Security in the form specified for such series is issued in exchange for any portion of a permanent global
Security after the close of business at the office or agency where such exchange occurs on (i) any Regular Record Date and before the opening of business at such office or agency on the relevant Interest Payment Date, or (ii) any Special
Record Date and before the opening of business at such office or agency on the related proposed date for payment of interest or Defaulted Interest, as the case may be, such interest or Defaulted Interest will not be payable on such Interest Payment
Date or proposed date for payment, as the case may be, in respect of such security in the form specified for such series, but will be payable on such Interest Payment Date or proposed date for payment, as the case may be, only to the Person to whom
interest in respect of such portion of such permanent global Security is payable in accordance with the provisions of this Indenture. 
 All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligation of the Company, evidencing the same debt, and entitled to the same benefits under this
Indenture, as the Securities surrendered upon such registration of transfer or exchange. 
 Every Security presented or
surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly
executed by the Holder thereof or his attorney duly authorized in writing. 
 Unless otherwise provided in the Securities to be
transferred or exchanged, no service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 3.04, 9.06 or 11.07 not involving any transfer. 
 The Company shall not be required (i) to issue, register the transfer of or exchange Securities of any series during a period beginning at the opening of business 15 days before the day of the
mailing of a notice of redemption of Securities of that series selected for redemption under Section 11.03 and ending at the close of business on the day of such mailing, or (ii) to register the transfer of

  
 28 

 
or exchange any security so selected for redemption in whole or in part, except the unredeemed portion of any security being redeemed in part. 

Section 3.06. Mutilated, Destroyed, Lost and Stolen Securities. If any mutilated Security is surrendered to the Trustee, the
Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding. 

If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of
any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a
protected purchaser, the Company shall execute and upon its request the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like tenor and principal amount and
bearing a number not contemporaneously outstanding. 
 In case any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security. 

Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. 
 Every new Security of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or
not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder.

 The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with
respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. 
 Section 3.07. Payment of
Interest; Interest Rights Preserved. Interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid at the Place of Payment to the Person in whose name that Security (or one or
more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, except that at the option of the Company payment may be made (i) except in the case of a global Security by check mailed to the
address of the Person entitled thereto as such address appears in the Security Registrar or (ii) by transfer to an account 

  
 29 

 
maintained by the Person entitled thereto as specified in the Security Registrar provided that proper transfer instructions have been received by the Regular Record Date. 

Any interest on any Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment
Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its
election in each case, as provided in Clause (1) or (2) below: 
 (1) The Company may elect to make
payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest,
which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the
Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit, in each case prior to the date
of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this Section 3.07 provided. Thereupon the Trustee shall fix a Special Record Date for the payment of
such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall
promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage
prepaid, to each Holder of Securities of such series at his address as it appears in the Security Register, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record
Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date
and shall no longer be payable pursuant to the following Clause (2). 
 (2) The Company may make payment of any
Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if,
after notice given by the Company to the Trustee of the proposed 

  
 30 

 
payment pursuant to this Section 3.07, such manner of payment shall be deemed practicable by the Trustee. 
 Subject to the foregoing provisions of this Section, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the
rights to interest accrued and unpaid, and to accrue, which were carried by such other Security. 
 Section 3.08. Persons
Deemed Owners. Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security
for the purpose of receiving payment of principal of (and premium, if any) and (subject to Section 3.07) interest on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the
Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. 
 None of the Company, the
Trustee or any agent of the Company or the Trustee shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interest of a Security in global form, or for maintaining,
supervising or reviewing any records relating to such beneficial ownership interest. Notwithstanding the foregoing, with respect to any Security in global form, nothing herein shall prevent the Company or the Trustee or any agent of the Company or
the Trustee from giving effect to any written certification, proxy or other authorization furnished by any U.S. Depositary or Common Depositary (or its nominee), as a Holder, with respect to such Security in global form or impair, as between such
U.S. Depositary or Common Depositary and owners of beneficial interests in such Security in global form, the operation of customary practices governing the exercise of the right of such U.S. Depositary or Common Depositary (or its nominee) as holder
of such Security in global form. 
 Section 3.09. Cancellation. All Securities surrendered for payment, redemption,
registration of transfer or exchange or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to
the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities
shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities shall be held by the Trustee and may be destroyed (and, if so
destroyed, certification of their destruction shall be delivered to the Company upon its request, unless, by a Company Order, the Company shall direct that cancelled Securities be returned to it). 

  
 31 

 Section 3.10. Computation of Interest. Except as otherwise specified as contemplated
by Section 3.01 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a 360-day year consisting of twelve 30-day months. 

ARTICLE 4 

SATISFACTION AND DISCHARGE 

Section 4.01. Satisfaction and Discharge of Indenture. This Indenture shall cease to be of further effect (except as to any
surviving rights of registration of transfer or exchange of Securities herein expressly provided for or in the form of Security for such series), when the Trustee, upon Company Request and at the expense of the Company, shall execute proper
instruments acknowledging satisfaction and discharge of this Indenture, when 
 (a) either 

(i) all Securities theretofore authenticated and delivered (other than (A) Securities which have been destroyed,
lost or stolen and which have been replaced or paid as provided in Section 3.06 and (B) Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the
Company or discharged from such trust, as provided in Section 10.08) have been delivered to the Trustee for cancellation; or

pay and discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, for principal (and premium, if any) and interest to the date of such deposit (in the case of Securities which have become due and
payable) or the Stated Maturity or Redemption Date, as the case may be; 

  
 32 

 (b) the Company has paid or caused to be paid all other sums payable hereunder by the
Company; and 
 (c) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each

Section 6.14 and, if money shall have been deposited with the Trustee pursuant to subclause (ii) of clause (a) of this Section, the obligations of the Trustee under Section 4.02 and the last paragraph of Section 10.08 shall
survive. 
 Section 4.02. Application of Trust Money. Subject to the provisions of the last paragraph of
Section 10.08, all money deposited with the Trustee pursuant to Section 4.01 shall be held in trust and applied by it, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with or received

 ARTICLE 5 
 REMEDIES 
 Section 5.01. Events of Default. “Event
of Default,” wherever used herein with respect to Securities 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 to 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): 
 (a) the Company defaults in the payment of interest or any sinking fund payment on any Security of that series when such interest becomes due and payable and the default continues for a period of 30 days;
provided, however, that if the Company is permitted by the terms of the Securities of the applicable series to defer the payment in question, the date on which such payment is due and payable shall be the date on which the Company is required to
make payment following such deferral, if such deferral has been elected pursuant to the terms of the Securities; or 
 (b) the
Company defaults in the payment of the principal of (or premium, if any, on) any Security of that series when the same becomes due and payable at Maturity, upon acceleration or redemption (including redemptions

  
 33 

 
under Article 11), by declaration or otherwise; provided, however, that if the Company is permitted by the terms of the Securities of the applicable series to defer the payment in question, the
date on which such payment is due and payable shall be the date on which the Company is required to make payment following such deferral, if such deferral has been elected pursuant to the terms of the Securities; or 

(c) the Company fails to observe or perform in any material respect any of its other covenants, warranties or agreements in the
Securities of that series or in this Indenture (other than a covenant, agreement or warranty a default in whose performance or whose breach is elsewhere in this Section specifically dealt with or which has expressly been included in this Indenture
solely for the benefit of series of Securities other than that series), and the failure to observe or perform continues for the period and after the notice specified in the last paragraph of this Section; or 

(d) any event of default, as defined in any other indenture, mortgage or instrument under which there may be issued, or by which there
may be secured or evidenced, any Indebtedness of the Company (whether such Indebtedness now exists or shall hereafter be created or incurred) shall occur and shall consist of default in the payment of such Indebtedness at the maturity thereof (after
giving effect to any applicable grace period) or shall result in Indebtedness becoming or being declared due and payable prior to the date on which it would otherwise become due and payable, and such default in payment is not cured or such
acceleration shall not be rescinded or annulled within 30 days after written notice to the Company from the Trustee or to the Company and to the Trustee from the Holders of at least 25% in aggregate principal amount of the Securities of that series
at the time outstanding; provided that it shall not be an Event of Default if the principal amount of Indebtedness (other than Indebtedness represented by Securities issued pursuant to this Indenture) which is not paid at maturity or the maturity of
which is accelerated is less than or equal to $50 million, and provided further that if, prior to a declaration of acceleration of the maturity of the Securities of that series or the entry of judgment in favor of the Trustee in a suit pursuant to
Section 5.03, such default shall be remedied or cured by the Company or waived by the holders of such Indebtedness, then the Event of Default hereunder by reason thereof shall be deemed likewise to have been thereupon remedied, cured or waived
without further action upon the part of either the Trustee or any of the Holders of the Securities of that series, and provided further that, subject to Sections 6.01 and 6.02, the Trustee shall not be charged with knowledge of any such default
unless written notice of such default shall have been given to the Trustee by the Company, by a holder or an agent of a holder of any such Indebtedness, by the trustee then acting under any indenture or other instrument under which such default
shall have occurred, or by the Holders of at least five percent in aggregate principal amount of the Securities of that series at the time Outstanding; or 

  
 34 

 (e) the Company pursuant to or within the meaning of any Bankruptcy Law (i) commences a
voluntary case or proceeding under any Bankruptcy Law with respect to itself, (ii) consents to the entry of a judgment, decree or order for relief against it in an involuntary case or proceeding under any Bankruptcy Law, (iii) consents to
or acquiesces in the institution of bankruptcy or insolvency proceedings against it, (iv) applies for, consents to or acquiesces in the appointment of or taking possession by a Custodian of the Company or for any material part of its property,
(v) makes a general assignment for the benefit of its creditors or (vi) takes any corporate action in furtherance of or to facilitate, conditionally or otherwise, any of the foregoing; or 

(f) (i) a court of competent jurisdiction enters a judgment, decree or order for relief in respect of the Company in an involuntary case
or proceeding under any Bankruptcy Law which shall (A) approve as properly filed a petition seeking reorganization, arrangement, adjustment or composition in respect of the Company, (B) appoint a Custodian of the Company or for any
material part of its property, or (C) order the winding-up or liquidation of its affairs, and such judgment, decree or order shall remain unstayed and in effect for a period of 60 consecutive days; or (ii) any bankruptcy or insolvency
petition or application is filed, or any bankruptcy or insolvency proceeding is commenced against the Company and such petition, application or proceeding is not dismissed within 60 days; or (iii) a warrant of attachment is issued against any
material portion of the property of the Company which is not released within 60 days of service; or 
 (g) any other Event of
Default provided with respect to Securities of that series in any indenture supplemental hereto. 
 A Default under clause
(c) above is not an Event of Default until the Trustee or the Holders of at least 25% in aggregate principal amount of the Outstanding Securities of that series notify the Company of the Default and the Company does not cure the Default within
90 days after receipt of the notice. The notice must specify the Default, demand that it be remedied and state that the notice is a “Notice of Default.” When a Default under clause (c) above is cured within such 90-day period, it
ceases. 
 Section 5.02. Acceleration of Maturity; Rescission and Annulment. If an Event of Default with respect to
Securities of any series (other than an Event of Default specified in clause (e) or (f) of Section 5.01) occurs and is continuing, the Trustee by notice in writing to the Company, or the Holders of at least 25% in aggregate principal
amount of the Outstanding Securities of that series by notice in writing to the Company and the Trustee, may declare the unpaid principal of and accrued interest to the date of acceleration (or, if the Securities of that series are Original Issue
Discount Securities, such portion of the principal amount as may be specified in the terms of that series) on all the Outstanding Securities of that series to be due and payable immediately and, upon any such declaration, the Outstanding Securities
of that series (or specified principal amount) shall become and be immediately due and payable. 

  
 35 

 If an Event of Default specified in clause (e) or (f) of Section 5.01 occurs,
all unpaid principal of and accrued interest on the Outstanding Securities of that series (or specified principal 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 of any Security of that series. 
 Upon payment of all such principal and interest, all of the Company’s
obligations under the Securities of that series and (upon payment of the Securities of all series) this Indenture shall terminate, except obligations under Section 6.07. 
 The Holders of a majority in principal amount of the Outstanding Securities of that series by notice to the Trustee may rescind an acceleration and its consequences if (i) all existing Events of
Default, other than the nonpayment of the principal and interest of the Securities of that series that has become due solely by such declaration of acceleration, have been cured or waived, (ii) to the extent the payment of such interest is
lawful, interest on overdue installments of interest and overdue principal that has become due otherwise than by such declaration of acceleration have been paid, (iii) the rescission would not conflict with any judgment or decree of a court of
competent jurisdiction and (iv) all payments due to the Trustee and any predecessor Trustee under Section 6.07 have been made. 
 Section 5.03. Collection of Indebtedness and Suits for Enforcement by Trustee. The Company covenants that if: 
 (a) default is made in the payment of any interest on any Security of any series when such interest becomes due and payable and such default continues for a period of 30 days, or 

(b) default is made in the payment of the principal of (or premium, if any, on) any Security of any series at the Maturity thereof, the
Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal (and premium, if any) and interest and, to the extent that payment of such
interest shall be legally enforceable, interest on any overdue principal (and premium, if any) and on any overdue interest, at the rate or rates prescribed therefor in such Securities, and, in addition thereto, such further amount as shall be
sufficient to cover the reasonable costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 

If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon such Securities and collect the moneys
adjudged or decreed to be payable in the manner provided by law out of 

  
 36 

 
the property of the Company or any other obligor upon such Securities, wherever situated. 
 If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of
Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to secure any other proper remedy. 
 Section 5.04. Trustee May File Proofs of
Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the
property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether
the Trustee shall have made any demand on the Company for the payment of overdue principal or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise, 

(a) to file and prove a claim for the whole amount of principal (and premium, if any) and interest owing and unpaid in respect of the
Securities and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agent
and counsel) and of the Holders allowed in such judicial proceedings, and 
 (b) to collect and receive any moneys or other
property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to
make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances
of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 6.07. 
 Nothing herein
contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof
or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
 Section 5.05. Trustee
May Enforce Claims Without Possession of Securities. All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of

  
 37 

 
the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and
any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of
which such judgment has been recovered. 
 Section 5.06. Application of Money Collected. Any money collected by the
Trustee pursuant to this Article in respect of the Securities of any series shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal (or premium, if
any) or interest, upon presentation of the Securities in respect of which moneys have been collected and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: 

First: To the payment of all amounts due the Trustee under Section 6.07 applicable to such series; 

Second: To the payment of the amounts then due and unpaid for principal of (and premium, if any) and interest on the Securities of such
series in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities of such series for principal (and premium, if any)
and interest, respectively; and 
 Third: To the Company. 

The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 5.06. At least 15 days before
such record date, the Trustee shall mail to each Holder and the Company a notice that states the record date, the payment date and the amount to be paid. 
 Section 5.07. Limitation on Suits. No Holder of any Security of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless: 
 (a) such Holder has previously given written
notice to the Trustee of a continuing Event of Default with respect to the Securities of that series; 
 (b) the Holders of not
less than 25% in principal amount of the Outstanding Securities of that series shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; 

(c) such Holder or Holders have offered to the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in
compliance 

  
 38 

 
with such request (including the reasonable and documented compensation, expenses and disbursements of its agents and counsel); 

(d) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding;
and 
 (e) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the
Holders of a majority in principal amount of the Outstanding Securities of that series; it being understood and intended that no one or more of Holders of Securities of any series shall have any right in any manner whatever by virtue of, or by
availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this
Indenture, except in the manner herein provided and for the equal and ratable benefit of all Holders of Securities of the affected series. 
 Section 5.08. Unconditional Right of Holders to Receive Principal, Premium And Interest. Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right,
which is absolute and unconditional, to receive payment of the principal of (and premium, if any) and (subject to Section 3.07) interest on such Security on the Stated Maturity or Maturities expressed in such Security (or, in the case of
redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder. 
 Section 5.09. Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored
severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding has been instituted. 

Section 5.10. Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 3.06, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 

  
 39 

 Section 5.11. Delay or Omission Not Waiver. No delay or omission of the Trustee or of
any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by
this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. 

Section 5.12. Control by Holders. The Holders of a majority in principal amount of the Outstanding Securities of any series shall
have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Securities of such series, provided that:

 (a) such direction shall not be in conflict with any rule of law or with this Indenture; 

(b) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction; and 

(c) subject to Section 6.01, the Trustee need not take any action which might involve the Trustee in personal liability or be unduly
prejudicial to the Holders not joining therein. 
 Section 5.13. Waiver of Past Defaults. The Holders of not less than a
majority in principal amount of the Outstanding Securities of any series may by written notice to the Trustee on behalf of the Holders of all the Securities of such series waive any Default or Event of Default with respect to such series and its
consequences, except a Default or Event of Default: 
 (a) in respect of the payment of the principal of (or premium, if any) or
interest on any Security of such series, or 
 (b) in respect of a covenant or other provision hereof which under Article 9
cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected. 
 Upon any such waiver,
such Default or Event of Default shall cease to exist and shall be deemed to have been cured, for every purpose of this Indenture and the Securities of such series; but no such waiver shall extend to any subsequent or other Default or Event of
Default or impair any right consequent thereon. 
 Section 5.14. Undertaking for Costs. All parties to this Indenture
agree, and each Holder of any Security by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the
Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that 

  
 40 

 
such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the
claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Company, to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in
the aggregate more than 10% in principal amount of the Outstanding Securities of any series, or to any suit instituted by any Holder for the enforcement of the payment of the principal of (or premium, if any) or interest on any Security on or after
the Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on or after the Redemption Date). 

ARTICLE 6 

THE TRUSTEE 
 Section 6.01. Certain Duties and Responsibilities of the Trustee. 
 (a)
Except during the continuance of an Event of Default, the Trustee’s duties and responsibilities under this Indenture shall be governed by Section 315(a) of the Trust Indenture Act. 

(b) In case an Event of Default has occurred and is continuing, and is known to the Trustee, the Trustee shall exercise the rights and
powers vested in it by this Indenture, and shall use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs. 

(c) None of the provisions of Section 315(d) of the Trust Indenture Act shall be excluded from this Indenture. 

Section 6.02. Notice of Defaults. Within 30 days after the occurrence of any Default or Event of Default with respect to the
Securities of any series, the Trustee shall give to all Holders of Securities of such series, as their names and addresses appear in the Security Register, notice of such Default or Event of Default known to the Trustee, unless such Default or Event
of Default shall have been cured or waived; provided, however, that, except in the case of a Default or Event of Default in the payment of the principal of (or premium, if any) or interest on any Security of such series or in the payment of any
sinking fund installment with respect to Securities of such series, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or directors or Responsible Officers of the Trustee in
good faith determine that the withholding of such notice is in the interest of the Holders of Securities of such series. 

Section 6.03. Certain Rights of Trustee. Subject to the provisions of the Trust Indenture Act: 

  
 41 

 (a) the Trustee may rely and shall be protected in acting or refraining from acting upon any
resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or
presented by the proper party or parties; 
 (b) any request or direction of the Company mentioned herein shall be sufficiently
evidenced by a Company Request or Company Order and any resolution of the Board of Directors may be sufficiently evidenced by a Board Resolution; 
 (c) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee
(unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officer’s Certificate; 
 (d) the Trustee may consult at the Company’s expense with counsel or other professional advisors of its selection and the written advice of such counsel or advisor or any Opinion of Counsel shall be
full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon; 
 (e) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless
such Holders shall have offered to the Trustee security or indemnity to its reasonable satisfaction against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction (including the reasonable and
documented compensation, expenses and disbursements of its agents and counsel); 
 (f) prior to the occurrence of an Event of
Default with respect to the Securities of any series and after the curing or waiving of all such Events of Default which may have occurred, the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution,
certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, approval or other paper or document, or the books and records of the Company, unless requested in writing to do so by the Holders of a majority in
principal amount of the Outstanding Securities of any series; provided, however, that if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it (including the reasonable and documented
compensation, expenses and disbursements of its agents and counsel) in the making of such investigation is not, in the opinion of the Trustee, reasonably assured to the Trustee by the security afforded to it by the terms of this Indenture, the
Trustee may require reasonable indemnity against such costs, expenses or liabilities as a condition to so proceeding; the reasonable expense of every such 

  
 42 

 
investigation shall be paid by the Company or, if paid by the Trustee, shall be repaid by the Company upon demand; 
 (g) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any
misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder; 
 (h) the Trustee shall
not be required to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of its rights or powers, if it shall have reasonable grounds for believing that
repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it; 
 (i) except in
connection with compliance with Section 310 or Section 311 of the Trust Indenture Act, the Trustee shall only be charged with knowledge of Responsible Officers; 
 (j) the Trustee shall not be charged with knowledge of any Default (other than payment Defaults when also acting as sole Paying Agent) unless the Trustee has received a written notice of such Default from
the Company or from any Holder of Securities; 
 (k) the Trustee shall not be liable for any action it takes or omits to take in
good faith which it believes to be authorized or within its rights or powers conferred upon it by this Indenture; 
 (l) upon an
Event of Default, the Trustee shall be entitled to require all agents to act solely in accordance with its directions; and 

(m) in all instances in which the Trustee is called upon to exercise its discretion under this Indenture, such discretion shall be
absolute, provided that the Trustee exercises such discretion in accordance with the provisions of this Indenture. 
 Section
6.04. Not Responsible for Recitals or Issuance of Securities. The recitals herein and in the Securities, except the Trustee’s certificates of authentication, shall be taken as the statements of the Company, and the Trustee or any
Authenticating Agent assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities. Neither the Trustee nor any Authenticating Agent shall be
accountable for the use or application by the Company of Securities or the proceeds thereof. 
 Section 6.05. May Hold
Securities. The Trustee, its Affiliates, any Authenticating Agent, any Paying Agent, any Security Registrar or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Securities and, subject to
Sections 6.08 and 6.13, may 

  
 43 

 
otherwise deal with the Company with the same rights it would have if it were not Trustee, an Affiliate, Authenticating Agent, Paying Agent, Security Registrar or such other agent. 

Section 6.06. Money Held in Trust. Money held by the Trustee in trust hereunder (including amounts held by the Trustee as Paying
Agent) need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed upon in writing with the Company. 

Section 6.07. Compensation and Reimbursement. The Company agrees 

(a) to pay to the Trustee from time to time reasonable compensation for all services rendered by it hereunder (which compensation shall
not be limited by any provision of law in regard to the compensation of a trustee of an express trust); 
 (b) except as
otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable
compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its gross negligence or bad faith; and 

(c) to indemnify the Trustee, any predecessor Trustee, and their respective officers, directors and employees for, and to hold them
harmless against, any loss, liability, damage, claim or expense, including taxes (other than taxes based upon or determined or measured by the income of the Trustee) and reasonable and documented counsel fees, incurred without gross negligence or
bad faith on their part, arising out of or in connection with the acceptance or administration of the trust or trusts hereunder, including the costs and expenses of defending themselves against any claim or liability in connection with the exercise
or performance of any of their powers or duties hereunder. 
 To secure the payment obligations of the Company in this
Section 6.07, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee, except that held in trust for the benefit of the Holders of particular Securities. 

When the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 5.01(e) or
Section 5.01(f), the expenses (including the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute expenses of administration under any applicable federal or state bankruptcy,
insolvency or other similar law. 
 If the Trustee is acting as Paying Agent and/or Security Registrar hereunder, the rights and
protections afforded to the Trustee under Article 6, 

  
 44 

 
including indemnification, will also be afforded to the Paying Agent and/or Security Registrar. 
 The provisions of this Section 6.07 shall survive this Indenture and the resignation or removal of any Trustee hereunder. 
 Section 6.08. Disqualification; Conflicting Interests. The Trustee shall be disqualified only where such disqualification is required by Section 310(b) of the Trust Indenture Act. Nothing
shall prevent the Trustee from filing with the Commission the application referred to in the second to last paragraph of Section 310(b) of the Trust Indenture Act.

Act having a combined capital and surplus of at least $5,000,000 subject to supervision or examination by federal or state authority. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of
said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so
published. Neither the Company nor any Person directly or indirectly controlling, controlled by, or under common control with the Company may serve as Trustee. If at any time the Trustee shall cease to be eligible in accordance with the provisions
of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. 
 Section
6.10. Resignation and Removal; Appointment of Successor. (a) No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the
successor Trustee in accordance with the applicable requirements of Section 6.11. 
 (b) The Trustee may resign at any time
with respect to the Securities of one or more series by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 6.11 shall not have been delivered to the Trustee within 30 days
after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 

(c) The Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of a majority in principal
amount of the Outstanding Securities of such series, delivered to the Trustee and to the Company. 
 (d) If at any time:

  
 45 

 (i) the Trustee shall fail to comply with Section 310(b) of the Trust
Indenture Act after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Security for at least six months; or 
 (ii) the Trustee shall cease to be eligible under Section 6.09 and shall fail to resign after written request here for by the Company or by any such Holder of a Security who has been a bona fide
Holder of a Security for at least six months; or 
 (iii) the Trustee shall become incapable of acting or shall
be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or
liquidation; 
 then, in any such case, (A) the Company by a Board Resolution may remove the Trustee with respect to all Securities, or
(B) subject to Section 315(e) of the Trust Indenture Act, any Holder who has been a bona fide Holder of a security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees. 
 (e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect to the Securities of one or more series, the
Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one
or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply with the applicable requirements of Section 6.11. If, within one year after such
resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of
such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 6.11, become the successor
Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company with respect to such Securities. If no successor Trustee with respect to the Securities of any series shall have been
so appointed by the Company or the Holders and accepted appointment in the manner required by Section 6.11, any Holder who has been a bona fide Holder of a security of such series for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 

  
 46

respect to the Securities of any series and each appointment of a successor Trustee with respect to the Securities of any series by mailing written notice of such event by first-class mail, postage prepaid, to all Holders of Securities of such
series as their names and addresses appear in the Security Register. Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the address of its Corporate Trust Office. 

Section 6.11. Acceptance of Appointment by Successor or Additional Trustees. 

(a) In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee so appointed
shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without
any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring
Trustee hereunder. 
 (b) In case of the appointment hereunder of a Trustee or a successor with respect to the Securities of one
or more (but not all) series, the Company, any retiring Trustee and each Trustee or a successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each Trustee or a
successor Trustee shall accept such appointment and which (i) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each Trustee or a successor Trustee all the rights, powers, trusts and
duties of any retiring Trustee with respect to the Securities of that or those series to which the appointment of such Trustee or a successor Trustee relates, (ii) if any retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of any retiring Trustee with respect to the Securities of that or those series as to which any retiring Trustee is not
retiring shall continue to be vested in any retiring Trustee, and (iii) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than
one Trustee, it being understood that nothing herein or in such supplemental Indenture shall constitute such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective

  
 47 

 
to the extent provided therein and each such Trustee or a successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of any
retiring Trustee with respect to the Securities of that or those series to which the appointment of such Trustee or a successor Trustee relates; but, on request of the Company or any Trustee or a successor Trustee, any such retiring Trustee shall,
upon payment of its charges, duly assign, transfer and deliver to such Trustee or a successor Trustee all property and money held by any such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment
of any such Trustee or successor Trustee relates. 
 (c) Upon request of any such successor Trustee, the Company shall execute
any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in paragraph (a) or (b) of this Section, as the case may be. 

(d) No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and
eligible under the Trust Indenture Act. 
 Section 6.12. Merger, Conversion, Consolidation or Succession to Business. Any
corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all
or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper
or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee
may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities. 
 Section 6.13. Preferential Collection of Claims Against Company. The Trustee shall comply with Section 311(a) of the Trust Indenture Act, excluding any creditor relationship listed in
Section 311(b) of the Trust Indenture Act. A Trustee who has resigned or been removed shall be subject to Section 311(a) of the Trust Indenture Act to the extent indicated therein. 

Section 6.14. Appointment of Authenticating Agent. At any time when any of the Securities remain Outstanding, the Trustee may
appoint an Authenticating Agent or Agents with respect to one or more series of Securities which shall be authorized to act on behalf of, and subject to the direction of, the Trustee to authenticate Securities of such series issued upon exchange,
registration of transfer or partial redemption thereof or pursuant to Section 3.06, and Securities so authenticated shall be entitled to the benefits of this Indenture 

  
 48 

 
and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by
the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the
Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United States of America, any State thereof or the District
of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $5,000,000 and subject to supervision or examination by federal or State authority. If such Authenticating Agent publishes
reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall
resign immediately in the manner and with the effect specified in this Section. 
 Any corporation into which an Authenticating
Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate
agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on
the part of the Trustee or the Authenticating Agent. 
 An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or
upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company
and shall mail written notice of such appointment by first-class mail, postage prepaid, to all Holders of Securities of the series with respect to which such Authenticating Agent will serve, as their names and addresses appear in the Security
Register. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No
successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section. 
 The Company agrees to
pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section. 

  
 49 

 If an appointment with respect to one or more series is made pursuant to this Section, the
Securities of such series may have endorsed thereon, in lieu of the Trustee’s certificate of authentication, an alternate certificate of authentication in the following form:

(b) at such other times as the Trustee may request in writing, within 30 days after the receipt by the Company of any such request, a
list of similar form and content as of a date not more than 15 days prior to the time such list is furnished. 
 Section 7.02.
Preservation of Information; Communications to Holders. 
 (a) The Trustee shall preserve, in as current a form as is
reasonably practicable, the names and addresses of Holders contained in the most recent list furnished to the Trustee as provided in Section 7.01 and the names and addresses of Holders received by the Trustee in its capacity as Security
Registrar. The Trustee may destroy any list furnished to it as provided in Section 7.01 upon receipt of a new list so furnished. 

  
 50 

 (b) If three or more Holders (herein referred to as “applicants”) apply in
writing to the Trustee, and furnish to the Trustee reasonable proof that each such applicant has owned a Security for a period of at least six months preceding the date of such application, and such application states that the applicants desire to
communicate with other Holders with respect to their rights under this Indenture or under the Securities and is accompanied by a copy of the form of proxy or other communication which such applicants propose to transmit, then the Trustee shall,
within five Business Days after the receipt of such application, at its election, either: 
 (i) afford such
applicants access to the information preserved at the time by the Trustee in accordance with Section 7.02(a); or 
 (ii) inform such applicants as to the approximate number of Holders whose names and addresses appear in the information preserved at the time by the Trustee in accordance with Section 7.02(a), and as
to the approximate cost of mailing to such Holders the form of proxy or other communication, if any, specified in such application. 
 If the Trustee shall elect not to afford such applicants access to such information, the Trustee shall, upon the written request of such applicants, mail to each Holder whose name and address appears in
the information preserved at the time by the Trustee in accordance with Section 7.02(a) a copy of the form of proxy or other communication which is specified in such request, with reasonable promptness after a tender to the Trustee of the
material to be mailed and of payment, or provision for the payment, of the reasonable expenses of mailing, unless within five days after such tender the Trustee shall mail to such applicants and file with the Commission, together with a copy of the
material to be mailed, a written statement to the effect that, in the opinion of the Trustee, such mailing would be contrary to the best interest of the Holders or would be in violation of applicable law. Such written statement shall specify the
basis of such opinion. If the Commission, after opportunity for a hearing upon the objections specified in the written statement so filed, shall enter an order refusing to sustain any of such objections or if, after the entry of an order sustaining
one or more of such objections, the Commission shall find, after notice and opportunity for hearing, that all objections so sustained have been met and shall enter an order so declaring, the Trustee shall mail copies of such material to all such
Holders with reasonable promptness after the entry of such order and the renewal of such tender; otherwise the Trustee shall be relieved of any obligation or duty to such applicants respecting their application. 

(c) Every Holder of Securities, by receiving and holding the same, agrees with the Company and the Trustee that neither the Company nor
the Trustee nor any agent of either of them shall be held accountable by reason of the disclosure of any such information as to the names and addresses of the Holders in accordance with Section 7.02(b), regardless of the source from which such

  
 51 

 
information was derived, and that the Trustee shall not be held accountable by reason of mailing any material pursuant to a request made under Section 7.02(b). 

Section 7.03. Reports by Trustee.

the reporting date with respect to a series of Securities, no report need be transmitted to Holders of such series. 
 (b) A
copy of each such report shall, at the time of such transmission to Holders, be filed by the Trustee with each stock exchange upon which any Securities are listed, with the Commission and with the Company. The Company will notify the Trustee when
any Securities are listed on any stock exchange. 
 Section 7.04. Reports by Company. 

(a) The Company will file with the Trustee and the Commission, and transmit to the Holders, such information, documents and other
reports, and such summaries thereof, as may be required pursuant to the Trust Indenture Act or Section 13 or 15(d) of the Exchange Act at the times and in the manner provided pursuant to such Acts; provided that any such information, documents
or reports required to be filed with the Commission pursuant to Section 13 or 15(d) of the Exchange Act shall be deemed to have been filed with the Trustee upon submission by the Company to the Commission of such information, documents or
reports, but only so long as such information, documents or reports are publicly available through the Commission’s Electronic Data Gathering, Analysis and Retrieval system. 

(b) Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt
of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is
entitled to conclusively rely exclusively on Officer’s Certificates). 
 (c) The Company shall furnish to the Trustee, on

 (g) to establish the form or terms of

taxes, assessments and governmental charges levied or imposed upon the Company or any Subsidiary or upon the income, profits or property of the Company or any Subsidiary material to the Company and its Subsidiaries taken as a whole, and (b) all
lawful claims for labor, materials and supplies which, if unpaid, might by law become a material lien upon the property of the Company or any Subsidiary material to the Company and its Subsidiaries taken as a whole; provided, however, that the
Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings and for which adequate
provision has been made. 
 Section 10.05. Compliance Certificates. 

(a) The Company shall deliver to the Trustee, within 10 days after the occurrence thereof, notice of any acceleration which with the
giving of notice and the lapse of time would be an Event of Default within the meaning of Section 5.01(d) hereof. 
 (b)
The Company shall deliver to the Trustee forthwith upon becoming aware of a Default or Event of Default (but in no event later than 10 days after the occurrence of each Default or Event of Default that is continuing), an Officer’s Certificate
setting forth the details of such Default or Event of Default and the action that the Company proposes to take with respect thereto and the specific section or sections of this Indenture in connection with which such Default or Event of Default has

 58 

 Section 10.06. Commission Reports. 

(a) So long as the Securities remain outstanding, the Company shall cause its annual report to shareholders and any other financial
reports furnished by it to shareholders generally, to be mailed to the Holders at their addresses appearing in the register of Securities maintained by the Security Registrar in each case at the time of such mailing or furnishing to shareholders. If
the Company is not required to furnish annual reports to its shareholders pursuant to the Exchange Act, the Company shall cause its financial statements, including any notes thereto and, with respect to annual reports, an auditors’ report by an
accounting firm of established national reputation and a “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” to be so filed with the Trustee and mailed to the Holders within 90 days after the end
of each of the Company’s fiscal years and within 45 days after the end of each of the first three quarters of each fiscal year. 
 (b) The Company shall provide the Trustee with a sufficient number of copies of all reports and other documents and information that the Company may be required to deliver to the Holders under this
Section 10.06. 
 Section 11.07. Waiver of Stay, Extension or Usury Laws. 

The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner
whatsoever claim, and will actively resist any and all efforts to be compelled to take the benefit or advantage of, any stay or extension law or any usury law or other law, which would prohibit or forgive the Company from paying all or any portion
of the principal of and/or interest on the Securities as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture; and (to the extent that it may lawfully do
so) the Company hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such
power as though no such law had been enacted. 
 Section 10.08. Money for Securities Payments to Be Held in Trust.

 If the Company shall at any time act as its own Paying Agent with respect to any series of Securities, it will, on or before
each due date of the principal of (and premium, if any) or interest on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal (and premium, if any) or
interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act. 

Whenever the Company shall have one or more Paying Agents for any series of Securities, it will, prior to each due date of the principal
of (and premium, 

  
 59 

 
if any) or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay the principal (and premium, if any) or interest so becoming due, such sum to be held in
trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure to so act. 

The Company will cause each Paying Agent for any series of Securities (other than the Trustee) to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will: 
 (a) hold all sums held by it for the payment of the principal of (and premium, if any) or interest on Securities of that series in trust for the benefit of the Persons entitled thereto until such sums
shall be paid to such Persons or otherwise disposed of as herein provided; 
 (b) give the Trustee notice of any default by the
Company (or any other obligor upon the Securities of that series) in the making of any payment of principal (and premium, if any) or interest on the Securities of that series; and 

(c) at any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all
sums so held in trust by such Paying Agent. 
 The Company may at any time, for the purpose of obtaining the satisfaction and
discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as
those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money. 

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of (and
premium, if any) or interest on any security of any series and remaining unclaimed for two years after such principal (and premium, if any) or interest has become due and payable shall be paid to the Company on Company Request, or (if then held by
the Company) shall be discharged from such trust; and the Holder of such security shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof unless any abandoned property law designates another Person, and all
liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any
such repayment, may at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in New York, New

  
 60 

 
York, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such
money then remaining will be repaid to the Company. 
 ARTICLE 11 

REDEMPTION OF SECURITIES 

Section 11.01. Applicability of Article. 
 Securities of any series which are redeemable before their Stated Maturity shall be redeemable in accordance with their terms in whole or in part (provided Securities issued in denominations larger than
$1,000 may be redeemed in part only in integral multiples of $1,000) and (except as otherwise specified as contemplated by Section 3.01 for Securities of any series) in accordance with this Article. 

Section 11.02. Election to Redeem; Notice to Trustee. 
 The election of the Company to redeem any Securities shall be evidenced by a Board Resolution. In case of any redemption at the election of the Company of less than all the Securities of any series, the
Company shall, at least 45 days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date and of the principal amount of Securities of such series to
be redeemed. In the case of any redemption of Securities prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an
Officer’s Certificate evidencing compliance with such restriction. 
 Section 11.03. 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
redeemed shall be selected not more than 90 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series not previously called for redemption, substantially pro rata, by lot or by any other method as the Trustee
considers fair and appropriate and that complies with the requirements of the principal national securities exchange, if any, on which such Securities are listed, and which may provide for the selection for redemption of portions (equal to the
lesser of the minimum authorized denomination for Securities of that series or $50 per Security, and any integral multiple thereof) of the principal amount of Securities of such series of a denomination larger than the minimum authorized
denomination for Securities of that series; provided that in case the Securities of such series have different terms and maturities, the Securities to be redeemed shall be selected by the Company and the Company shall give notice thereof to the
Trustee. 

  
 61 

 The Trustee shall promptly notify the Company in writing of the Securities selected for
redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed. 

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of the Securities
shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be redeemed. 

Section 11.04. Notice of Redemption. 
 Notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed, at this
address appearing in the Security Register. 
 All notices of redemption shall state: 

(a) the Redemption Date; 
 (b) the Redemption Price; 
 (c) if less than all the Outstanding Securities of any
series are to be redeemed, the identification (and, in the case of partial redemption, the principal amounts) of the particular Securities to be redeemed; 
 (d) that on the Redemption Date, the Redemption Price will become due and payable upon each such Security to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said
date; 
 (e) the place or places where such Securities are to be surrendered for payment of the Redemption Price; 

(f) that the redemption is for a sinking fund, if such is the case; 

(g) the CUSIP number, if any, of the Securities to be redeemed; and 

(h) unless otherwise provided as to a particular series of Securities, if at the time of publication or mailing of any notice of
redemption the Company shall not have deposited with the Trustee or Paying Agent and/or irrevocably directed the Trustee or Paying Agent to apply, from money held by it available to be used for the redemption of Securities, an amount in cash
sufficient to redeem all of the Securities called for redemption, including accrued interest to the Redemption Date, such notice shall state that it is subject to the receipt of the redemption moneys by the Trustee or Paying Agent before the
Redemption Date (unless such redemption is mandatory) and such notice shall be of no effect unless such moneys are so received before such date. 

  
 62 

 Notice of redemption of Securities to be redeemed at the election of the Company shall be
given by the Company or, at the Company’s request, by the Trustee in the name and at the expense of the Company. 
 Section
11.05. Deposit of Redemption Price. 
 Prior to any Redemption Date, the Company shall deposit with the Trustee or with a
Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 10.08) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest
Payment Date) accrued interest on, all the Securities which are to be redeemed on that date. 
 Section 11.06. Securities
Payable on Redemption Date. 
 Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall,
on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear
interest. Upon surrender of any such security for redemption in accordance with said notice, such security shall be paid by the Company at the Redemption Price, together with accrued interest to the Redemption Date; provided, however, that
installments of interest whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Regular or
Special Record Dates according to their terms and the provisions of Section 3.07. 
 If any Security called for redemption
shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate prescribed in the Security. 

Section 11.07. Securities Redeemed in Part. 
 Any Security which is to be redeemed only in part shall be surrendered at an office or agency of the Company at a Place of Payment therefor (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall
authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of the same series and Stated Maturity, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to
and in exchange for the unredeemed portion of the principal of the Security so surrendered. 

  
 63 

 ARTICLE 12 

SINKING FUNDS 
 Section 12.01. Applicability of Article. 
 The provisions of this Article
shall be applicable to any sinking fund for the retirement of Securities of a series, except as otherwise specified as contemplated by Section 3.01 for Securities of such series. 

The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a
“Mandatory Sinking Fund Payment,” and any payment in excess of such minimum amount provided for by the terms of Securities of any series is herein referred to as an “Optional Sinking Fund Payment.” If provided for
by the terms of Securities of any series, the cash amount of any sinking fund payment may be subject to redemption as provided in Section 12.02. Each sinking fund payment shall be applied to the redemption of Securities of any series as
provided for by the terms of Securities of such series. 
 Section 12.02. Satisfaction of Sinking Fund Payments with
Securities. 
 The Company (a) may deliver Securities of a series (other than any Securities previously called for
redemption) and (b) may apply as a credit Securities of a series which have been (i) previously cancelled pursuant to Section 3.09 or delivered for cancellation or (ii) redeemed either at the election of the Company pursuant to
the terms of such Securities or through the application of permitted Optional Sinking Fund Payments pursuant to the terms of such Securities, in each case in satisfaction of all or any part of any Mandatory Sinking Fund Payment with respect to the
Securities of such series required to be made pursuant to the terms of such Securities as provided for by the terms of such series; provided that such Securities have not been previously so credited. Such Securities shall be received and credited at
the principal amount for such purpose by the Trustee at the Redemption Price specified in such Securities for redemption through operation of the sinking fund and the amount of such Mandatory Sinking Fund Payment shall be reduced accordingly.

 Section 12.03. Redemption of Securities for Sinking Fund. 

Not less than 45 days prior to each sinking fund payment date for any series of Securities, the Company will deliver to the Trustee an
Officer’s Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any,
which is to be satisfied by delivering and crediting Securities of that series pursuant to Section 12.02 and will also deliver to the Trustee any Securities to be so delivered. Not less than 30 days before each such sinking fund payment date
the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the 

  
 64 

 
manner specified in Section 11.03 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 11.04. Such
notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 11.06 and 11.07. 
 ARTICLE 13 
 DEFEASANCE AND
COVENANT DEFEASANCE 
 Section 13.01. Applicability of Article; Company’s
Option to Effect Defeasance or Covenant Defeasance. 
 Unless pursuant to Section 3.01 provision is made for the
inapplicability of either or both of (a) Defeasance of the Securities of a series under Section 13.02 or (b) Covenant Defeasance of the Securities of a series under Section 13.03, then the provisions of such Section or Sections,
as the case may be, together with the other provisions of this Article, shall be applicable to the Securities of such series, and the Company may at its option by Board Resolution, at any time, with respect to the Securities of such series, elect to
have either Section 13.02 (unless inapplicable) or Section 13.03 (unless inapplicable) be applied to the Outstanding Securities of such series upon compliance with the applicable conditions set forth below in this Article. 

Section 13.02. Defeasance and Discharge. 
 Upon the Company’s exercise of the option provided in Section 13.01 to defease the Outstanding Securities of a particular series, the Company shall be discharged from its obligations with
respect to the Outstanding Securities of such series on the date the applicable conditions set forth in Section 13.04 are satisfied (hereinafter, “Defeasance”). Defeasance shall mean that the Company shall be deemed to have
paid and discharged the entire indebtedness represented by the Outstanding Securities of such series and to have satisfied all its other obligations under such Securities and this Indenture insofar as such Securities are concerned (and the Trustee,
at the expense of the Company, shall execute proper instruments acknowledging the same); provided, however, that the following rights, obligations, powers, trusts, duties and immunities shall survive until otherwise terminated or discharged
hereunder: (a) the rights of Holders of Outstanding Securities of such series to receive, solely from the trust fund provided for in Section 13.04, payments in respect of the principal of (and premium, if any) and interest on such
Securities when such payments are due, (b) the Company’s obligations with respect to such Securities under Sections 3.04, 3.05, 3.06, 10.02 and 10.08, (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and
(d) this Article. Subject to compliance with this Article, the Company may exercise its option with respect to Defeasance under this Section 13.02 notwithstanding the prior exercise of its option with respect to Covenant Defeasance under
Section 13.03 in regard to the Securities of such series. 

  
 65 

 Section 13.03. Covenant Defeasance. 

Upon the Company’s exercise of the option provided in Section 13.01 to obtain a Covenant Defeasance with respect to the
Outstanding Securities of a particular series, the Company shall be released from its obligations under this Indenture (except its obligations under Sections 3.04, 3.05, 3.06, 5.06, 5.09, 6.10, 10.01, 10.02, 10.05, 10.07 and 10.08) with respect to
the Outstanding Securities of such series on and after the date the applicable conditions set forth in Section 13.04 are satisfied (hereinafter, “Covenant Defeasance”). Covenant Defeasance shall mean that, with respect to the
Outstanding Securities of such series, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in this Indenture (except its obligations under Sections 3.04, 3.05, 3.06, 5.06, 5.09,
6.10, 10.01, 10.02, 10.05, 10.07 and 10.08), whether directly or indirectly by reason of any reference elsewhere herein or by reason of any reference to any other provision herein or in any other document, and such omission to comply shall not
constitute an Event of Default under Section 5.01(d) with respect to Outstanding Securities of such series, and the remainder of this Indenture and of the Securities of such series shall be unaffected thereby. 

Section 13.04. Conditions to Defeasance or Covenant Defeasance. 

The following shall be the conditions to Defeasance under Section 13.02 and Covenant Defeasance under Section 13.03 with
respect to the Outstanding Securities of a particular series: 
 (a) the Company shall irrevocably have deposited or caused to
be deposited (and in the case of Defeasance such deposit shall have been made 121 days prior to Defeasance with the Trustee (or another trustee satisfying the requirements of Section 6.09 who shall agree to comply with the provisions of this
Article applicable to it)), under the terms of an irrevocable trust agreement in form and substance reasonably satisfactory to such Trustee, as trust funds in trust for the purpose of making the following payments, specifically pledged as security
for, and dedicated solely to, the benefit of the Holders of such Securities, (i) Dollars in an amount, or (ii) U.S. Government Obligations which through the scheduled payment of principal and interest in respect thereof in accordance with
their terms will provide, not later than the due date of any payment, money in an amount, or (iii) a combination thereof, in each case sufficient, after payment of all federal, state and local taxes or other charges or assessments in respect
thereof payable by the Trustee, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee
(or other qualifying trustee) to pay and discharge, (A) the principal of (and premium, if any, on) and each installment of principal of (and premium, if any) and interest on the Outstanding Securities of such series on the Stated Maturity of
such principal or installment of principal or interest and (B) any mandatory sinking fund payments or analogous payments applicable to the 

  
 66 

 
Outstanding Securities of such series on the day on which such payments are due and payable in accordance with the terms of this Indenture and of such Securities. 

(b) No Default or Event of Default with respect to the Securities of such series shall have occurred and be continuing on the date of
such deposit or shall occur as a result of such deposit, and no Default or Event of Default under clause (e) or (f) of Section 5.01 hereof shall occur and be continuing, at any time during the period ending on the 31st day after the
date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period). 
 (c) Such deposit, Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any other agreement or instrument to which the Company is a party or by
which it is bound. 
 (d) In the case of an election with respect to Section 13.02, the Company shall have delivered to the
Trustee either (i) a ruling directed to the Trustee received from the Internal Revenue Service to the effect that the Holders of the Outstanding Securities of such series will not recognize income, gain or loss for federal income tax purposes
as a result of such Defeasance and will be subject to 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 had not occurred or (ii) an Opinion of Counsel, based on a
ruling published by the Internal Revenue Service or on a change in the applicable federal income tax law since the date of this Indenture, in either case to the effect that, and based thereon such opinion shall confirm that, the Holders of the
Outstanding Securities of such series will not recognize income, gain or loss for federal income tax purposes as a result of such Defeasance and will be subject to 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 had not occurred. 
 (e) In the case of an election with respect to
Section 13.03, the Company shall have delivered to the Trustee an Opinion of Counsel or a ruling directed to the Trustee received from the Internal Revenue Service to the effect that the Holders of the Outstanding Securities of such series will
not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such
Covenant Defeasance had not occurred. 
 (f) Such Defeasance or Covenant Defeasance shall be effected in compliance with any
additional terms, conditions or limitations which may be imposed on the Company in connection therewith pursuant to Section 3.01. 
 (g) The Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for relating to either the Defeasance under
Section 13.02 or the 

  
 67 

 
Covenant Defeasance under Section 13.03 (as the case may be) have been complied with. 
 Section 13.05. Deposited Money and Government Obligations to Be Held in Trust. 
 Subject to the provisions of the last paragraph of Section 10.08, all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying
trustee—collectively for purposes of this Section 13.05, the “Trustee”) pursuant to Section 13.04 in respect of the Outstanding Securities of a particular series shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities
of all sums due and to become due thereon in respect of principal (and premium, if any) and interest, but such money need not be segregated from other funds except to the extent required by law. 

The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government
Obligations deposited pursuant to Section 13.04 or the principal and interest received in respect thereof, other than any such tax, fee or other charge which by law is for the account of the Holders of the Outstanding Securities of such series.

 Anything in this Article to the contrary notwithstanding, the Trustee shall deliver to pay to the Company from time to time
upon Company Request any money or Government Obligations held by it as provided in Section 13.04 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to
the Trustee, are in excess of the amount thereof which would then be required to be deposited for the purpose for which such money or U.S. Government Obligations were deposited.

 FIRST SUPPLEMENTAL INDENTURE, dated as of February 14, 2012 (the “First
Supplemental Indenture”), between KENNAMETAL INC., a corporation duly organized and existing under the laws of the Commonwealth of Pennsylvania (the “Company”), and U.S. BANK NATIONAL ASSOCIATION, as trustee (the
“Trustee”). 
 WHEREAS, the Company executed and delivered the indenture dated as of February 14, 2012
(the “Base Indenture”), to the Trustee to provide for the future issuance of the Company’s unsecured debentures, notes or other evidence of indebtedness (the “Securities”), to be issued from time to time in one
or more series as determined by the Company under the Base Indenture;

 GENERAL TERMS AND CONDITIONS OF THE
NOTES 
 Section 2.01. Designation and Principal Amount. The Notes are hereby authorized and are
designated the 3.875% Senior Notes due 2022, unlimited in aggregate principal amount. The Notes issued on the date hereof pursuant to the terms of this Indenture will be in an aggregate principal amount of $300,000,000, which amount shall be set
forth in the written order of the Company for the authentication and delivery of the Notes pursuant to Section 3.03 of the Base Indenture. In addition, the Company may issue, from time to time in accordance with the provisions of this
Indenture, additional Notes ranking equally and ratably with the Notes issued hereunder in all respects (or in all respects except for the payment of interest following the Issue Date of such further Notes), so that such further Notes shall be
consolidated and form a single series with the Notes and shall be governed by the terms of this Indenture. 
 Section 2.02.
Maturity. The principal amount of the Notes will be payable on February 15, 2022. 
 Section 2.03. Form and Payment.
The Notes will be issued as global notes, in fully registered book-entry form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. 

Principal, premium, if any, and/or interest, if any, on the global notes representing the Notes will be made to The Depository Trust
Company (the “Depositary”). 
 The global notes representing the Notes will be deposited with, or on behalf of,
the Depositary and will be registered in the name of the Depositary or a nominee of the Depositary. No global note may be transferred except as a whole by a nominee of the Depositary to the Depositary or to another nominee of the

  
 8 

 
Depositary, or by the Depositary or such nominee to a successor of the Depositary or a nominee of such successor. 
 So long as the Depositary or its nominee is the registered owner of a global note, the Depositary or its nominee, as the case may be, will be the sole Holder of the Notes represented thereby for all
purposes under the Indenture. Except as otherwise provided herein, each actual purchaser of each Note represented by a global note (“Beneficial Owner”) will not be entitled to receive physical delivery of certificated Notes and will
not be considered the holders thereof for any purpose under the Indenture, and no global note representing the Notes shall be exchangeable or transferable. Accordingly, each Beneficial Owner must rely on the procedures of the Depositary and, if such
Beneficial Owner is not a participant, on the procedures of the participant through which such Beneficial Owner owns its interest in order to exercise any rights of a Holder under such global note or the Indenture. 

The global notes representing the Notes will be exchangeable for certificated Notes of like tenor and terms and of differing authorized
denominations aggregating a like principal amount, only if (i) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for the global notes, (ii) the Depositary ceases to be a clearing agency registered
under applicable law and a successor to the Depositary is not appointed by the Company within 90 days, (iii) the Company in its sole discretion determines that the global notes shall be exchangeable for certificated Notes and notifies the
Trustee of such determination or (iv) there shall have occurred and be continuing an Event of Default under the Indenture with respect to the Notes. Upon any such exchange, the certificated Notes shall be registered in the names of the
Beneficial Owners of the global notes representing the Notes, which names shall be provided by the Depositary’s relevant participants (as identified by the Depositary) to the Trustee. In such event the Company will execute, and subject to
Section 3.03 of the Base Indenture, the Trustee, upon receipt of an Officer’s Certificate evidencing such determination by the Company, will authenticate and deliver the Notes in definitive registered form without coupons, in authorized
denominations, and in an aggregate principal amount equal to the principal amount of the global notes in exchange for such global notes. Upon the exchange of the global notes for such Notes in definitive registered form without coupons, in
authorized denominations, the global notes shall be cancelled by the Trustee. Such Notes in definitive registered form issued in exchange for the global notes shall be registered in such names and in such authorized denominations as the Depositary,
pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver such Notes to the Depositary for delivery to the Persons in whose names such Notes are so registered. 

Section 2.04. Interest. The Notes shall bear interest at a rate equal to 3.875% per annum. Interest on the Notes shall accrue
from February 14, 2012, or from the most recent interest payment date to which interest has been paid or duly provided upon for the Notes, as the case may be. Interest on the Notes shall be

  
 9 

 
payable semi-annually in arrears on February 15 and August 15, commencing August 15, 2012 (each an “Interest Payment Date”), to the persons in whose names the
Notes are registered at the close of business on February 1 and August 1 (even if such date is not a Business Day), as the case may be, preceding such Interest Payment Date. 

ARTICLE 3 

REDEMPTION OF THE NOTES 

Section 3.01. Optional Redemption. The Notes will be redeemable, in whole or in part, at the option of the Company at any time,
upon not less than 30 nor more than 60 days’ notice. 
 If the Redemption Date occurs before the date that is three months
prior to the Stated Maturity, the Company will pay the Holders of the Notes being redeemed a Redemption Price equal to the greater of (i) 100% of the principal amount of their redeemed Notes, or (ii) as determined by the Independent
Investment Banker, the sum of the present values of the remaining principal amount and scheduled payments of interest on the Notes to be redeemed (not including the portion of any such payments of interest accrued as of the Redemption Date),
discounted to the Redemption Date in accordance with customary market practice on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 30 basis points, plus, in each case, accrued and unpaid
interest thereon to the Redemption Date. 
 If the Redemption Date occurs on or after the date that is three months prior to the
Stated Maturity, the Company will pay the Holders of the Notes being redeemed a Redemption Price equal to 100% of the principal amount of their redeemed Notes, plus accrued and unpaid interest thereon to the Redemption Date. 

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the
Notes, or portions thereof called for redemption. If less than all of the Notes are to be redeemed, the Trustee will select the Notes to be redeemed by such method as the Trustee shall deem fair and appropriate. The Trustee may select for redemption
Notes and portions of the Notes in principal amounts of $2,000 and any integral multiple of $1,000 in excess thereof. 
 Section
3.02. No Sinking Fund. The Notes are not entitled to the benefit of any sinking fund. 
 Section 3.03. Change of
Control Offer. 
 (a) If a Change of Control Triggering Event occurs, each Holder of the Notes will have the right to
require the Company to purchase all or a portion 

  
 10 

 
(equal to $2,000 principal amount and any integral multiples of $1,000 in excess thereof) of such Holder’s Notes pursuant to the offer described below (a “Change of Control
Offer”) at a purchase price equal to 101% of the aggregate principal amount of the Notes repurchased, plus accrued and unpaid interest, if any, to the date of repurchase (the “Change of Control Payment”), subject to the
rights of Holders of Notes on the relevant record date to receive interest due on the relevant Interest Payment Date. 
 (b) The
Company will be required to send a notice to each Holder of the Notes by first-class mail, with a copy to the Trustee, within 30 days following the date upon which any Change of Control Triggering Event occurred, or at the Company’s option,
prior to any Change of Control but after the public announcement of the pending Change of Control. The notice will govern the terms of the Change of Control Offer and will describe, among other things, the transaction that constitutes or may
constitute the Change of Control Triggering Event and the purchase date. The purchase date will be at least 30 days but no more than 60 days from the date such notice is mailed, other than as may be required by law (a “Change of Control
Payment Date”). If the notice is mailed prior to the date of consummation of the Change of Control, the notice will state that the Change of Control Offer is conditioned on the Change of Control being consummated on or prior to the Change
of Control Payment Date. 
 (c) On the Change of Control Payment Date, the Company will, to the extent lawful: 

(i) accept for payment all properly tendered Notes or portions of Notes not validly withdrawn; 

(ii) deposit with the Paying Agent the required payment for all properly tendered Notes or portions of Notes not validly
withdrawn; and 
 (iii) deliver or cause to be delivered to the Trustee the repurchased Notes, accompanied by an
Officer’s Certificate stating, among other things, the aggregate principal amount of repurchased Notes. 
 (d) The Company
will not be required to make a Change of Control Offer with respect to the Notes upon the occurrence of a Change of Control Triggering Event if a third party makes a Change of Control Offer in the manner, at the times and otherwise in compliance
with the requirements for such an offer made by the Company and the third party purchases all Notes properly tendered and not withdrawn under its Change of Control Offer. 
 (e) The Company will comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder, to the extent those laws and regulations are applicable,
in connection with the repurchase of Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with 

  
 11 

 
the Change of Control Offer provisions of the Notes, the Company will comply with those securities laws and regulations and will not be deemed to have breached the Company’s obligations
under the Change of Control Offer provisions of the Notes by virtue of any such conflict. 
 ARTICLE 4 

EVENTS OF DEFAULT 
 Section 4.01. Events of Default. Pursuant to Section 5.01(g) of the Base Indenture, “Event of Default” in respect of the Notes and only in respect of the Notes shall be deemed

 KENNAMETAL INC., a corporation duly organized and existing under the laws of the Commonwealth of
Pennsylvania (the “Company”, which term includes any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., or registered assigns, the principal sum of
Three Hundred Million dollars ($300,000,000) on February 15, 2022 (such date is hereinafter referred to as the “Maturity Date”), and to pay interest on said principal sum from February 14, 2012, or from the most recent
interest payment date (each such date, an “Interest Payment Date”) to which interest has been paid or duly provided for, semi-annually in arrears on February 15 and August 15 of each year, commencing on August 15,
2012, at the rate of 3.875% per annum until the principal hereof shall have become due and payable. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to
the Person in whose name this Note (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 close of business on the February 1 or August 1 (whether or
not a Business Day), as the case may be, preceding such Interest Payment Date. Any such interest not punctually paid or duly provided for shall forthwith cease to be payable to the registered Holders on such Regular Record Date and may be paid to
the Person in whose name this Note (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
registered Holders of this series of Notes 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 Notes of this
series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture. The principal of, and premium, if any, and the interest on this Note shall be payable at the office or agency of the Trustee

Trustee his or her attorney-in-fact for any and all such purposes. 
 This Note shall not be entitled to any benefit under the

 (REVERSE OF NOTE) 
 KENNAMETAL INC. 
 3.875% Senior Notes due 2022 

This Note is one of a duly authorized series of Securities of the Company (herein sometimes referred to as the
“Securities”) specified in the Indenture (as defined below), all issued or to be issued in one or more series under and pursuant to an Indenture dated as of February 14, 2012 (the “Base Indenture”), duly
executed and delivered between the Company and U.S. Bank National Association, as Trustee (the “Trustee”), as supplemented by a First Supplemental Indenture, dated February 14, 2012 (the Base Indenture as so supplemented, the
“Indenture”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and
the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. By the terms of the Indenture, the Securities are issuable in series that may vary as to amount, date of maturity, rate of
interest and in other respects as provided in the Indenture. 
 The Notes are not entitled to the benefit of any sinking fund.

 The Notes will be redeemable, in whole or in part, at the option of the Company at any time, upon not less than 30 nor more
than 60 days’ notice. If the Redemption Date occurs before the date that is three months prior to the Stated Maturity, the Company will pay the Holders of the Notes being redeemed a Redemption Price equal to the greater of (i) 100% of the
principal amount of their redeemed Notes, or (ii) as determined by the Independent Investment Banker, the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed (not including the
portion of any such payments of interest accrued as of the Redemption Date) discounted to the Redemption Date in accordance with customary market practice on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the
Treasury Rate plus 30 basis points, plus, in each case, accrued and unpaid interest thereon to the Redemption Date. If the Redemption Date occurs on or after the date that is three months prior to the Stated Maturity, the Company will pay the
Holders of the Notes being redeemed 100% of the principal amount of their redeemed Notes, plus accrued and unpaid interest on the redeemed thereon to the Redemption Date. Unless the Company defaults in payment of the Redemption Price, on and after
the Redemption Date, interest will cease to accrue on the Notes or portions thereof called for redemption. 
 If less than all
of the Notes of a series are to redeemed, the Trustee will select the Notes to be redeemed by such method as the Trustee shall deem fair and appropriate. The Trustee may select for redemption Notes and portions of Notes in principal amounts of whole
multiples of $2,000 and any integral multiple of $1,000 in excess thereof. 

  
 5 

 Upon the occurrence of a Change of Control Triggering Event (as defined in the Indenture),
Holders will have the right to require the Company to repurchase the Notes on the terms and conditions set forth in the Indenture. 
 The Indenture contains provisions for defeasance of (a) the entire indebtedness of this Note and (b) certain restrictive covenants upon compliance by the Company with certain conditions set
forth therein. 
 In case an Event of Default shall have occurred and be continuing, the principal of all of the Notes may be
declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture. 
 The Indenture contains provisions permitting the Company and the Trustee, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes of each series affected at
the time Outstanding, to execute supplemental indentures for the purpose of, among other things, adding any provisions to or changing or eliminating any of the provisions of the Indenture or of any supplemental indenture or of modifying the rights
of the Holders of the Notes; provided, however, that, among other things, no such supplemental indenture shall (i) reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon (subject to the
Company’s right to defer such payments in the manner set forth herein), or reduce any premium payable upon the redemption thereof, without the consent of the Holder of each Note so affected, or (ii) reduce the aforesaid percentage of
Notes, the Holders of which are required to consent to any such supplemental indenture, without the consent of the Holders of each Note then Outstanding and affected thereby. The Indenture also contains provisions permitting, among other things, the
Holders of a majority in aggregate principal amount of the Securities of any series at the time Outstanding affected thereby, on behalf of all of the Holders of all Securities of such series, to waive a Default or Event of Default with respect to
such series, and its consequences, except a Default or Event of Default in the payment of the principal of or premium, if any, or interest on any of the Securities of such series. Any such consent or waiver by the registered Holder of this Note
(unless revoked as provided in the Indenture) shall be conclusive and binding upon such Holder and upon all future Holders and owners of this Note and of any Note issued in exchange for or in place hereof (whether by registration of transfer or
otherwise), irrespective of whether or not any notation of such consent or waiver is made upon this Note. 
 No reference herein
to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and premium, if any, and interest on this Note at the times, place
and at the rates and in the money herein prescribed. 

  
 6 

 As provided in the Indenture and subject to certain limitations therein set forth, this Note
is transferable by the registered Holder hereof on the Security Register of the Company, upon surrender of this Note for registration of transfer at the office or agency of the Trustee in Pittsburgh, Pennsylvania duly endorsed by, or accompanied by,
a written instrument or instruments of transfer in form satisfactory to the Company or the Trustee duly executed by the registered Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes of authorized
denominations and for the same aggregate principal amount and series will be issued to the designated transferee or transferees. No service charge will be made for any such transfer, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in relation thereto. 
 Prior to due presentment for registration of transfer of
this Note, the Company, the Trustee, any Paying Agent and the Security Registrar may deem and treat the registered Holder hereof as the absolute owner hereof (whether or not this Note shall be overdue and notwithstanding any notice of ownership or
writing hereon made by anyone other than the Security Registrar) for the purpose of receiving payment of or on account of the principal hereof and premium, if any, and interest due hereon and for all other purposes, and neither the Company nor the
Trustee nor any Paying Agent nor any Security Registrar shall be affected by any notice to the contrary. 
 No recourse shall be
had for the payment of the principal of or the interest on this Note, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture, against any incorporator, shareholder, officer or director, past,
present or future, as such, of the Company or of any predecessor or successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, and such liability being, by
the acceptance hereof and as part of the consideration for the issuance hereof, expressly waived and released. 
 The Indenture
imposes certain limitations on the ability of the Company to, among other things, merge or consolidate with any other Person, sell, assign, transfer or lease all or substantially all of its properties or assets or create or incur liens on certain of
its property. All such covenants and limitations are subject to a number of important qualifications and exceptions. The Company must report periodically to the Trustee on compliance with the covenants in the Indenture. 

A director, officer, employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company
under the Notes of this series or the Indenture or for any claim based on, in respect of or by reason of, such obligations or their creation. Each Holder, by accepting a Note, waives and releases all such liability. The waiver and release are part
of the consideration for the issuance of this Note. 

  
 7 

 Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification
Procedures (“CUSIP”), the Company has caused CUSIP numbers to be printed on the Notes. No representation is made as to the correctness or accuracy of such numbers as printed on the Notes and reliance may be placed only on the other
identification numbers printed hereon. 
 The Notes of this series are issuable only in fully registered book-entry form without
coupons in denominations of $2,000 and any integral multiple of $1,000 in excess thereof. This Global Note is exchangeable for Notes in definitive form only under certain limited circumstances set forth in the Indenture. As provided in the Indenture
and subject to certain limitations therein set forth, Notes of this series so issued are exchangeable for a like aggregate principal amount of Notes of this series of a different authorized denomination, as requested by the Holder surrendering the
same. 
 This Note shall be governed by and construed in accordance with the law of the State of New York. 

All terms used in this Note that are defined in the Indenture shall have the meanings assigned to them in the Indenture.
