Section 1.3 Form of Documents Delivered to Trustee. 

In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that
all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other

certificate or opinion of an officer of the Company may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such officer knows, or in the exercise of reasonable care should know,
that the certificate or opinion or representations with respect to the matters upon which his or her certificate or opinion is based are erroneous. Any such certificate or opinion of counsel may be based, insofar as it relates to factual
matters, upon a certificate or opinion of, or representations by, an officer or officers of the Company stating that the information with respect to such factual matters is in the possession of the Company, unless such counsel knows, or in the
exercise of reasonable care should know, that the certificate or opinion or representations with respect to such matters are erroneous. 

Any such certificate or opinion of an officer of the Company or of counsel may be based, insofar as it relates to accounting matters, upon a
certificate or opinion of, or representations by, an accountant or firm of accountants in the employ of the Company, unless such officer or counsel, as the case may be, knows, that the certificate or opinion or representations with respect to the

execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument. 

  
 -11- 

 Section 1.4 Acts of Holders; Record Dates. 

Any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given,
made 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 an agent 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. The Trustee shall promptly deliver to the Company copies of any such instrument or
instruments delivered to the Trustee. 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 6.1) conclusive in favor of the Trustee and the Company, if made
in the manner provided in this Section. 
 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 or her
the execution thereof. Where such execution is by a signer acting in a capacity other than his or her individual capacity, such certificate or affidavit shall also constitute sufficient proof of his or her 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 that the Trustee deems sufficient. 

The ownership of Securities shall be proved by the Security Register. 

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. 
 The Company may set any day as a record date for the
purpose of determining the Holders of Outstanding Securities of any series entitled to give, make or take any request, demand, authorization, direction, vote, notice, consent, waiver or other action provided or permitted by this Indenture to be
given, made or taken by Holders of Securities of such series. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of the relevant series on such record date, and no other Holders, shall be entitled to
take the relevant action, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite
principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Company from setting a new record date for any action for which a record date has previously been set
pursuant to this paragraph (whereupon the record 

  
 -12- 

 
date previously set shall automatically and with no action by any Person be canceled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by
Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice
of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 1.6. 

With respect to any record date set pursuant to this Section, the Company may designate any day as the “Expiration Date” and from
time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the Trustee in writing, and to each Holder of Securities of the
relevant series in the manner set forth in Section 1.6, on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to this Section, the Company shall be deemed to have
initially designated the 180th day after such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be
later than the 180th day after the applicable record date. 
 Without limiting the foregoing, a Holder entitled hereunder to take any action
hereunder with regard to any particular Security may do so with regard to all or any part of the principal amount of such Security or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any
part of such principal amount. 
 Section 1.5 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, 
 (1) the Trustee by any Holder or by the Company shall be
sufficient for every purpose hereunder if made, given, furnished or filed in writing (or by facsimile transmissions, provided that oral confirmation of receipt shall have been received) to or with the Trustee at its Corporate Trust Office,
Attention: Corporate Trust Department, or 
 (2) 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 by first-class postage prepaid, personally delivered or sent via overnight courier to the Company addressed to it at the address of its principal office
specified in the first paragraph of this instrument or at any other address previously furnished in writing to the Trustee by the Company, Attention: Chief Financial Officer. 

  
 -13- 

 Section 1.6 Notice to Holders; Waiver. 

Where this Indenture provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly
provided) if in writing and mailed by first-class postage prepaid, or delivered by hand or overnight courier, to each Holder affected by such event, at its address as it appears in the Security Register, not later than the latest date (if any), and
not earlier than the earliest date (if any), prescribed for the giving of such notice. Neither the failure to mail or deliver by hand or overnight courier any notice, nor any defect in any notice so mailed or delivered by hand or overnight
courier, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Indenture 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 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. 

Section 1.7 Conflict with Trust Indenture Act. 

If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act that is required under the Trust Indenture
Act to be a part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act, which may be so modified or excluded, the latter provision
shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be. 
 Section 1.8 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 1.9 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, the holders of Senior Debt 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 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 or the last date on which a Holder has
the right to convert a Security at a particular conversion price or conversion rate, as the case may be, shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or of the Securities (other
than a provision of any Security which specifically states that such provision shall apply in lieu of this Section)) payment of interest or principal (and premium, if any) or, if applicable to a particular series of Securities, conversion need not
be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on the Interest Payment Date or Redemption Date, at the Stated Maturity or on such
last day for conversion, as the case may be. 
 Section 1.14 Indenture and Securities Solely Corporate Obligations. 

No recourse for the payment of the principal of or premium, if any, or interest on any Security, or for any claim based thereon or otherwise in
respect thereof, and no recourse under or upon any obligation, covenant or agreement of the Company in this Indenture or in any supplemental indenture or in any Security, or because of the creation of any indebtedness represented thereby, shall be
had against any incorporator, stockholder, employee, agent, officer, or director or subsidiary, as such, past, present or future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation,
whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood that all such liability is hereby expressly waived and released as a condition of, and as a
consideration for, the execution of this Indenture and the issue of the Securities. 
 Section 1.15 Indenture May be Executed in Counterparts. 

This instrument may be executed in any number of counterparts, each of which shall be an original, but such counterparts shall together
constitute but one and the same instrument.

 If any of the terms of the series are established by action

Certificate (including any exhibit attached thereto) setting forth the terms of the series.

 -20- 

 Section 3.3 Execution, Authentication, Delivery and Dating. 

The Securities shall be executed on behalf of the Company by its Chairman of the Board, its Vice Chairman of the Board, its Chief Executive
Officer, its principal financial officer, its principal accounting officer, its President or one of its executive officers, and attested by its Treasurer, its Secretary or one of its Assistant Treasurers or Assistant Secretaries. The signature
of any of these officers on the Securities may be manual or facsimile. 
 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 deliver such Securities. If the form or terms of the Securities of the series have been established by or pursuant to one or more Board Resolutions as permitted by Sections 2.1 and 3.1, 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 Section 6.1) shall be fully protected in relying upon, a certified copy of such Board
Resolution, an Officers’ Certificate setting forth the terms of the series or supplemental indenture hereto and an Opinion of Counsel (which opinion of Counsel may contain customary qualifications and exceptions), with such Opinion of Counsel
stating, 
 (1) if the form of such Securities has been established by or pursuant to Board Resolution as permitted by
Section 2.1, that such form has been established in conformity with the provisions of this Indenture; 
 (2) if the
terms of such Securities have been established by or pursuant to Board Resolution as permitted by Section 3.1, that such terms have been established in conformity with the provisions of this Indenture; and 

(3) 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 binding obligations of the Company enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and
similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles. 
 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. 

  
 -21- 

 Notwithstanding the provisions of Section 3.1 and of this Section 3.3, if all
Securities of a series are not to be originally issued at one time, it shall not be necessary to deliver an Officers’ Certificate or supplemental indenture hereto otherwise required pursuant to Section 3.1 or the Company Order and Opinion
of Counsel otherwise required pursuant to this Section 3.3 at or prior to the 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. 
 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. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the
Trustee for cancellation as provided in Section 3.9, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture. 

Neither the Company nor the Trustee shall have any responsibility for any defect in the CUSIP number that appears on any Security, check,
advice of payment or redemption notice, and any such document may contain a statement to the effect that CUSIP numbers have been assigned by an independent service for convenience of reference and that neither the Company nor the Trustee shall be
liable for any inaccuracy in such numbers. 
 Section 3.4 Temporary Securities. 

Pending the preparation of definitive Securities of any series, the Company may execute, and upon Company Order the Trustee shall authenticate
and deliver, 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 officers executing such Securities may determine, as evidenced by their execution of such Securities. 

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 deliver in exchange therefor one or more definitive Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount. 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 and tenor. 

  
 -22- 

 Section 3.5 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 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 a series at the office or agency of the Company in a Place of Payment for that
series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same series, of any authorized denominations and of like tenor and
aggregate principal amount. 
 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 like tenor and aggregate principal amount, 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 deliver, the Securities that the Holder making the exchange is entitled to receive. All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations
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 its attorney duly authorized in writing. 

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 3.4, 9.6 or 11.7 not involving any transfer. 

If the Securities of any series (or of any series and specified tenor) are to be redeemed in part, the Company shall not be required
(A) to issue, register the transfer of or exchange any Securities of that series (or of that series and specified tenor, as the case may be) during a period beginning at the opening of business 15 days before the day of the mailing of a notice
of redemption of any such Securities selected for redemption under Section 11.3 and ending at the close of business on the day of such mailing, or (B) to register the transfer of or exchange any Security so selected for redemption in whole
or in part, except the unredeemed portion of any Security being redeemed in part. 
 The provisions of clauses (1), (2), (3) and
(4) below shall apply only to Global Securities: 

  
 -23- 

 (1) Each Global Security authenticated under this Indenture shall be registered
in the name of the Depositary designated for such Global Security or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single Security for all purposes of
this Indenture. 
 (2) Notwithstanding any other provision in this Indenture, no Global Security may be exchanged in whole
or in part for Securities registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any Person other than the Depositary for such Global Security or a nominee thereof unless (A) such Depositary
(i) has notified the Company that it is unwilling or unable to continue as Depositary for such Global Security or (ii) has ceased to be a clearing agency registered under the Exchange Act, (B) there shall have occurred and be
continuing an Event of Default with respect to such Global Security or (C) there shall exist such circumstances, if any, in addition to or in lieu of the foregoing as have been specified for this purpose as contemplated by Section 3.1.

 (3) Subject to clause (2) above, any exchange of a Global Security for other Securities may be made in whole or in
part, and all Securities issued in exchange for a Global Security or any portion thereof shall be registered in such names as the Depositary for such Global Security shall direct. 

(4) Every Security authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global
Security or any portion thereof, whether pursuant to this Section, Section 3.4, 3.6, 9.6 or 11.7 or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such Security is registered in the name
of a Person other than the Depositary for such Global Security or a nominee thereof. 
 Section 3.6 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 bona
fide purchaser, the Company shall execute and 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. 

  
 -24- 

 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 3.7 Payment of Interest; Interest Rights Preserved. 

Except as otherwise provided as contemplated by Section 3.1 with respect to any series of Securities, interest on any Security which is
payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid 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. 
 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 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 clause 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 

  
 -25- 

 
Interest and the Special Record Date therefor to be given to each Holder of Securities of such series in the manner set forth in Section 1.6, 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 given, 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 payment pursuant to
this clause, 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 3.8 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 any premium and (subject to Section 3.7) any 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. 
 Section 3.9 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 canceled 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 may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Company has not
issued and sold, and all Securities so delivered shall be promptly canceled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled as provided in this Section, except as expressly permitted by
this Indenture. All canceled Securities held by the Trustee shall be disposed of in accordance with its customary procedures. 

  
 -26- 

 Section 3.10 Computation of Interest. 

Except as otherwise specified as contemplated by Section 3.1 for Securities of any series, interest on the Securities of each series shall
be computed on the basis of a 360-day year of twelve 30-day months. 
 ARTICLE 4

debts generally as they become due, or the taking of corporate action by the Company in furtherance of any such action; or 

(7) any other Event of Default provided with respect to Securities of that series in the Board Resolution (or in an
Officers’ Certificate detailing such establishment pursuant to such Board Resolution) or supplemental indenture establishing that series. 
 Section
5.2 Acceleration of Maturity; Rescission and Annulment. 
 (a) Unless the Board Resolution (or Officers’ Certificate detailing such
establishment pursuant to such Board Resolution) or supplemental indenture establishing such series provides 

  
 -29- 

 
otherwise, if an Event of Default (other than an Event of Default specified in Section 5.1(5) or 5.1(6)) with respect to Securities of any series at the time Outstanding occurs and is
continuing, then in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of that series may declare the principal amount of all the Securities of that series (or, if any Securities of that
series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof), and premium, if any, together with accrued and unpaid interest, if any, thereon, to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders), and upon any such declaration such principal amount (or specified amount), and premium, if any, together with accrued and unpaid interest, if any,
thereon, shall become immediately due and payable. If an Event of Default specified in Section 5.1(5) or 5.1(6) with respect to Securities of any series at the time Outstanding occurs, the principal amount of all the Securities of that
series (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof), and premium, if any, together with accrued and unpaid interest,
if any, thereon, shall automatically, and without any declaration or other action on the part of the Trustee or any Holder, become immediately due and payable. Any payments by the Company on the Securities following any such acceleration will
be subject to the subordination provisions of Article 15 to the extent provided therein. 
 (b) Notwithstanding the foregoing, at the
election of the Company, the sole remedy with respect to an Event of Default for the failure by the Company to comply with its obligations under Section 314(a)(1) of the Trust Indenture Act relating to the Company’s failure to file any
documents or reports that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act or of its covenants set forth in Section 7.4 (any such Event of Default, a “Reporting Default”), shall for
the first 180 calendar days after the occurrence of such Reporting Default consist exclusively of the right to receive additional interest (the “Additional Interest”) on the Securities at an annual rate equal to (i) 0.25% of the
principal amount of the Securities for the first 90 calendar days after the occurrence of such Reporting Default and (ii) 0.50% of the principal amount of the Securities from the 91st day to, and including, the 180th day after the occurrence of
such Reporting Default. If the Company so elects, the Additional Interest shall accrue on all Outstanding Securities from and including the date on which such Reporting Default first occurs until such violation is cured or waived and shall be
payable as provided in Section 3.7. On the 181st day after such Reporting Default (if such violation is not cured or waived prior to such 181st calendar day), then the Trustee or the Holders of not less than 25% in principal amount of the
Outstanding securities may declare the principal of, and premium, if any, together with accrued and unpaid interest, if any, on all such Securities to be due and payable immediately. 

If the Company elects to pay the Additional Interest as the sole remedy for the Reporting Default, the Company shall notify in writing, by a
certificate, the Holders, the Paying Agent and the Trustee of such election at any time on or before the close of business on the first Business Day following the date on which such Event of Default first occurs. Unless and until a Responsible
Officer of the Trustee receives at the Corporate Trust Office such a certificate, the Trustee may assume without inquiry that Additional Interest is not payable. The Company shall pay the Additional Interest semi-annually in arrears, with the
first semi-annual payment due on the first 

  
 -30- 

 
Interest Payment Date following the date of such Reporting Default, in the same manner as described on the face of the Security. 

(c) At any time after such a declaration of acceleration with respect to Securities of any series has been made and before a judgment or
decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Securities of that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if 
 (1) the Company has paid or deposited with the
Trustee a sum sufficient to pay 
 (A) all overdue interest on all Securities of that series, 

(B) the principal of (and premium, if any, on) any Securities of that series which have become due otherwise than by such
declaration of acceleration and any interest thereon at the rate or rates prescribed therefor in such Securities, 
 (C) to
the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor in such Securities, and 

(D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances
of the Trustee, its agents and counsel; and 
 (2) all Events of Default with respect to Securities of that series, other
than the non-payment of the principal of Securities of that series that have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 5.13. 

No such rescission shall affect any subsequent default or impair any right consequent thereon. 

Section 5.3 Collection of Indebtedness and Suits for Enforcement by Trustee. 

The Company covenants that if 

(1) default is made in the payment of the principal or the Redemption Price of (or premium, if any, on) any Security at the
Maturity thereof, or 
 (2) default is made in the payment of any interest on any Security when such interest becomes due
and payable and such default continues for a period of 30 days. 
 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 any premium and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and premium and
on any overdue interest, at the rate or rates prescribed 

  
 -31- 

 
therefor in such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel. 
 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 enforce any other proper remedy. 

Section 5.4 Trustee May File Proofs of Claim. 

In case of any judicial proceeding relative to the Company (or any other obligor upon the Securities), its property or its creditors, the
Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such
proceeding. In particular, the Trustee shall be authorized 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 6.7. No provision of this Indenture
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; provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be
a member of a creditors’ or other similar committee. 
 Section 5.5 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 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 5.6 Application of Money Collected. 

Any money collected by the Trustee pursuant to this Article 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 

  
 -32- 

 
account of principal or any premium or interest, upon presentation of the Securities 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 6.7; 

SECOND: Subject to Article 15, to the payment of the amounts then due and unpaid for principal of and any premium, if any, and interest
on the Securities 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 for principal and any premium, if any,
and interest, respectively; and 
 THIRD: The balance, if any, to the Company or any other Person or Persons entitled thereto. 

Section 5.7 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 

(1) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the
Securities of that series; 
 (2) the Holders of at least 25% in aggregate 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; 

(3) such Holder or Holders have offered to the Trustee reasonable indemnity against the costs, expenses and liabilities to be
incurred in compliance with such request; 
 (4) the Trustee for 60 days after its receipt of such notice, request and offer
of indemnity has failed to institute any such proceeding; and 
 (5) 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 such Holders 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 of such Holders. 

  
 -33- 

 Section 5.8 Unconditional Right of Holders to Receive Principal, Premium and Interest and to Convert. 

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 any premium and (subject to Section 3.7) interest on such Security on the respective Stated Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date), to convert such
Securities in accordance with Article 14 to the extent that such right to convert is applicable to such Security, 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 5.9 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 had 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 3.6, 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. 
 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 (subject to the limitations contained in this Indenture) 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 

  
 -34- 

 (1) such direction shall not be in conflict with any rule of law or with this
Indenture and the Trustee shall not have determined that the action so directed would be unjustly prejudicial to Holders of Securities of that series, or any other series, not taking part in such direction; and 

(2) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction or this
Indenture. 
 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 on behalf of the Holders of all the
Securities of such series waive any past default hereunder with respect to such series and its consequences, except 
 (1) a
default in the payment of the principal of or any premium or interest on any Security of such series as and when the same shall become due and payable by the terms thereof, otherwise than by acceleration (unless such default has been cured and a sum
sufficient to pay all matured installments of interest, principal and premium, if any, has been deposited with the Trustee), or 

(2) to the extent such right is applicable to such Security, a failure by the Company on request to convert any Security into
Common Stock; or 
 (3) in respect of a covenant or 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 shall
cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. 

Section 5.14 Undertaking for Costs. 
 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, a court may require any party litigant in such suit to file an undertaking to
pay the costs of such suit, and may assess costs against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided that neither this Section nor the Trust Indenture Act shall be deemed to authorize
any court to require such an undertaking or to make such an assessment in any suit instituted by the Company. 
 This Section does not apply
to a suit by a Holder to enforce payment of principal of or interest on any Security on the respective due dates, a suit by a Holder to enforce the right to convert in any suit for the enforcement of the right to convert any Security in accordance
with Article 14 to the extent such right to convert is applicable to such Security, or a suit by Holders of more than 10% in principal amount of the Outstanding Securities. 

  
 -35- 

 Section 5.15 Waiver of Usury, Stay or Extension 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 or take the benefit or advantage of, any usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that
it may lawfully do so) 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. 
 ARTICLE 6 

THE TRUSTEE 
 Section 6.1 Certain
Duties and Responsibilities. 
 The duties and responsibilities of the Trustee shall be as provided by the Trust Indenture Act and as set
forth herein. Notwithstanding the foregoing, no provision of this Indenture shall require the Trustee 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
any 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. Whether or not therein expressly so provided, every
provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section. 

Section 6.2 Notice of Defaults. 
 If a
default occurs hereunder with respect to Securities of any series, the Trustee shall give the Holders of Securities of such series notice of such default as and to the extent provided by the Trust Indenture Act; provided, however, that
except in the case of a default in the payment of principal or Redemption Price of (or premium, if any) or interest on any Securities of such series or in the payment of any sinking fund installment or any conversion right applicable to Securities
of such series, the Trustee shall be protected in withholding such notice if and so long as a trust committee of directors and/or Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interests of
the holders of Securities of such series; provided, further, however, that in the case of any default of the character specified in Section 5.1(4) with respect to Securities of such series, no such notice to Holders shall
be given until at least 60 days after the occurrence thereof. For the purpose of this Section, the term “default” means any event that is, or after notice or lapse of time or both would become, an Event of Default with respect to
Securities of such series. 
 Except with respect to Section 10.1, the Trustee shall have no duty to inquire as to the performance of
the Company with respect to the covenants contained in Article 10. In addition, the Trustee shall not be deemed to have knowledge of an Event of Default except (i) any Default or Event of Default occurring pursuant to
Sections 5.1(1), 5.1(2) and 5.1(3) (defaults in payments on 

  
 -36- 

 
the Securities) or (ii) any Default or Event of Default of which a Responsible Officer the Trustee shall have received written notification or obtained actual knowledge. 

Delivery of reports, information and documents to the Trustee under Section 7.4 is for informational purposes only and the Trustee’s
receipt of the foregoing shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of their covenants hereunder (as to which the
Trustee is entitled to rely conclusively on Officers’ Certificates). 
 Section 6.3 Certain Rights of Trustee. 

Subject to the provisions of Section 6.1: 

(1) in the absence of bad faith on the part of the Trustee, 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; 
 (2) 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 shall be sufficiently evidenced by a Board Resolution; 

(3) 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) is entitled to and may, in the absence of bad faith on its part, rely upon an Officers’ Certificate;

 (4) the Trustee may consult with counsel and the written advice of such counsel 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; 

(5) 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 reasonable security or indemnity against the costs, expenses and liabilities which might be incurred by it in compliance
with such request or direction; 
 (6) 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, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make
such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company,
personally or by agent or attorney; and 

  
 -37- 

 (7) 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. 

Section 6.4 Not Responsible for Recitals or Issuance of Securities. 

The recitals contained herein and in the Securities, except the Trustee’s certificates of authentication, shall be taken as the statements
of the Company, and neither the Trustee nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no representations as to the validity, sufficiency or priority 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
6.5 May Hold Securities and Act as Trustee under Other Indentures. 
 The Trustee, 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 6.8 and 6.13, may otherwise deal with the Company with the same rights it
would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent. 
 Subject to the limitations
imposed by the Trust Indenture Act, nothing in this Indenture shall prohibit the Trustee from becoming and acting as trustee under other indentures under which other securities, or certificates of interest of participation in other securities, of
the Company are outstanding in the same manner as if it were not Trustee hereunder. 
 Section 6.6 Money Held in Trust. 

Money held by the Trustee in trust hereunder 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 with the Company. 
 Section 6.7 Compensation and
Reimbursement. 
 The Company agrees: 

(1) 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); 

(2) 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

  
 -38- 

 
such expense, disbursement or advance as may be attributable to its negligence or bad faith; and 

(3) to indemnify the Trustee for, and to hold it harmless against, any loss, liability or expense incurred without negligence
or bad faith on its 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 itself against any claim or liability in connection with the exercise or
performance of any of its powers or duties hereunder. 
 When the Trustee incurs expenses or renders services after an Event of Default
specified in Section 5.1(5) or Section 5.1(6) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any
applicable bankruptcy, insolvency, reorganization or similar law. 
 Section 6.8 Conflicting Interests. 

If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act and there is an Event of Default under
the Securities of that series, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. To the extent permitted by the
Trust Indenture Act, the Trustee shall not be deemed to have a conflicting interest by virtue of being a trustee under this Indenture with respect to Securities of more than one series. 

Section 6.9 Corporate Trustee Required; Eligibility. 

There shall at all times be one (and only one) Trustee hereunder with respect to the Securities of each series, which may be Trustee hereunder
for Securities of one or more other series. Each Trustee shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has (or if the Trustee is a member of a bank holding company system, its bank holding company
has) a combined capital and surplus of at least $50,000,000. If any such Person or bank holding company publishes reports of condition at least annually, pursuant to law or to the requirements of its supervising or examining authority, then for
the purposes of this Section and to the extent permitted by the Trust Indenture Act, the combined capital and surplus of such Person or bank holding company 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 the Trustee with respect to the Securities of any series 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. 

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. 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 

  
 -39- 

 
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. 
 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. 

If at any time: 

(1) the Trustee shall fail to comply with Section 6.8 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 
 (2) the Trustee shall cease to be eligible under
Section 6.9 and shall fail to resign after written request therefor by the Company or by any such Holder, or 
 (3) 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 5.14, 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. 
 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. 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, the retiring Trustee may petition, or any Holder who has been a bona fide Holder of a Security of such series for at least six months may petition, on behalf of himself and all others

  
 -40- 

 
similarly situated, any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 

The Company shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series to all Holders of Securities of such series in the manner provided in Section 1.6. 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. 

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. 
 In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not
all) series, the Company, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment
and which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities
of that or those series to which the appointment of such successor Trustee relates, (2) if the 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 the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (3) 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 to the extent provided therein and each 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 with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company or any successor
Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such 

  
 -41- 

 
retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor Trustee relates. 

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 the first or second preceding paragraph, as the case may be. 

No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible
under this Article. 
 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 (including the administration of the trust created by this Indenture),
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. In the event that any Securities shall not have been authenticated by such predecessor Trustee, any such successor Trustee
may authenticate and deliver such Securities in either its own name or that of a predecessor Trustee, with the full force and effect which this Indenture provides for the certificate of authentication of the Trustee. 

Section 6.13 Preferential Collection of Claims Against Company. 

If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Securities), the Trustee shall be subject
to the provisions of the Trust Indenture Act regarding the collection of claims against the Company (or any such other obligor). 
 Section 6.14
Appointment of Authenticating Agent. 
 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 the Trustee to authenticate Securities of such series issued upon original issue and upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 3.6, and
Securities so authenticated shall be entitled to the benefits of this Indenture 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 

  
 -42- 

 
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 (or if the Authenticating Agent is a member of a bank holding company system, its bank holding company has) a combined capital and surplus of not less than $50,000,000 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 give notice of such appointment in the
manner provided in Section 1.6 to all Holders of Securities of the series with respect to which such Authenticating Agent will serve. 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 Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section, and the
Trustee shall be entitled to be reimbursed for such payments, subject to the provisions of Section 6.7. 
 If an appointment with
respect to one or more series is made pursuant to this Section 6.14, the Securities of such series may have endorsed thereon, in lieu of the Trustee’s certificate of authentication, an alternative certificate of authentication in the
following form: 
 This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

or changing in any manner or eliminating any of the provisions of this Indenture or of modifying in any manner the rights of the Holders of Securities of such series under this Indenture; provided, however, that no such supplemental

(2) modify the provisions of this Indenture with respect to the subordination of such series of Securities in a manner
materially adverse to the Holders of Securities of such series, or 
 (3) in the case of Securities of any series that are
convertible into Common Stock or other securities of the Company pursuant to Article 14 and any supplemental indenture hereto, adversely affect the rights of the Holders to convert any of the Securities of such series other than as provided in
or pursuant to this Indenture or any supplemental indenture, or

provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; provided, however, that this clause shall not be deemed to require
the consent of any Holder with respect to changes in the references to “the Trustee” and concomitant changes in this Section, or the deletion of this proviso, in accordance with the requirements of Sections 6.11 and 9.1(9). 

A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture which has expressly been included
solely for the benefit of one or more particular series of Securities, or which modifies the rights of the Holders of Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.

of the Trustee and the Company, to any such supplemental indenture may be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for Outstanding Securities of such series. 

Section 9.7 Subordination Unimpaired.

 COVENANTS

 Section 10.1 Payment of Principal, Premium and Interest. 

The Company covenants and agrees for the benefit of each series of Securities that it will duly and punctually pay the principal of and any
premium and interest on the Securities of that series in accordance with the terms of the Securities and this Indenture. 
 Section 10.2 Maintenance of
Office or Agency. 
 The Company will maintain in each Place of Payment for any series of Securities an office or agency where Securities
of that series may be presented or surrendered for payment, where Securities of that series may be surrendered for registration of transfer or exchange, where Securities of that series may be surrendered for conversion to the extent that such right
to convert is applicable to such Security and where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served. The Company will give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands. Unless otherwise
provided in a supplemental indenture or pursuant to Section 3.1 hereof, the Place of Payment for any series of Securities shall be the Corporate Trust Office of the Trustee. 

The Company may also from time to time designate one or more other offices or agencies where the Securities of one or more series may be
presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain
an 

  
 -50- 

 
office or agency in each Place of Payment for Securities of any series for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and
of any change in the location of any such other office or agency. 
 Section 10.3 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 or any premium 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 any premium and 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, on or prior to each due date of the principal
of or any premium or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Company
will promptly notify the Trustee of its action or failure so to 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 (1) comply with the provisions
of the Trust Indenture Act applicable to it as a Paying Agent and (2) during the continuance of any default by the Company (or any other obligor upon the Securities of that series) in the making of any payment in respect of the Securities of
that series, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent for payment in respect of the Securities of that series. 

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 amounts deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of or any
premium or interest on any Security of any series and remaining unclaimed for a period ending on the earlier of the date that is ten Business Days prior to the date such money would escheat to the State or two years after such principal, premium 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, 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 

  
 -51- 

 
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 each Place of Payment, 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. 

Section 10.4 Statement by Officers as to Default. 

The Company will deliver to the Trustee, within 120 days after the end of each fiscal year of the Company ending after the date hereof, an
Officers’ Certificate, stating whether or not to the best knowledge of the signers thereof the Company is in default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any
period of grace or requirement of notice provided hereunder) and, if the Company shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge. The fiscal year of the Company currently ends
on December 31; and the Company will give the Trustee prompt written notice of any change of its fiscal year. 
 Section 10.5 Existence. 

Subject to Article 8, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its
existence. 
 Section 10.6 Waiver of Certain Covenants. 

Except as otherwise specified as contemplated by Section 3.1 for Securities of such series, the Company may, with respect to the
Securities of any series, omit in any particular instance to comply with any term, provision or condition set forth in any covenant provided pursuant to Section 3.1(20) or 9.1(2) for the benefit of the Holders of such series if before the time
for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities of such series shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such term,
provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the
Trustee in respect of any such term, provision or condition shall remain in full force and effect. 
 ARTICLE 11 

REDEMPTION OF SECURITIES 
 Section 11.1
Applicability of Article. 
 Securities of any series that are redeemable before their Stated Maturity shall be redeemable in accordance
with their terms and (except as otherwise specified as contemplated by Section 3.1 for such Securities) in accordance with this Article. 

  
 -52- 

 Section 11.2 Election to Redeem; Notice to Trustee. 

The election of the Company to redeem any Securities shall be evidenced by a Board Resolution or in another manner specified as contemplated by
Section 3.1 for such Securities. In case of any redemption at the election of the Company of less than all the Securities of any series (including any such redemption affecting only a single Security), 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 or is specified in the Board Resolution (or in an Officers’ Certificate pursuant to such Board Resolution detailing such
establishment) or supplemental indenture establishing such series), notify the Trustee of such Redemption Date, of the principal amount of Securities of such series to be redeemed and, if applicable, of the tenor of the Securities to be redeemed.

 Section 11.3 Selection by Trustee of Securities to Be Redeemed. 

If less than all the Securities of any series are to be redeemed (unless all the Securities of such series and of a specified tenor are to be
redeemed or unless such redemption affects only a single Security), the particular Securities to be redeemed shall be selected not more than 45 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series not
previously called for redemption, by lot, or in the Trustee’s discretion, on a pro-rata basis, provided that the unredeemed portion of the principal amount of any Security shall be in an authorized denomination (which shall not be less
than the minimum authorized denomination) for such Security. If less than all the Securities of such series and of a specified tenor are to be redeemed (unless such redemption affects only a single Security), the particular Securities to be
redeemed shall be selected not more than 45 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series and specified tenor not previously called for redemption in accordance with the preceding sentence. 

If any Security selected for partial redemption is converted in part before termination of the conversion right with respect to the portion of
the Security so selected, the converted portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Securities that have been converted during a selection of Securities to be redeemed shall be treated
by the Trustee as Outstanding for the purpose of such selection. 
 The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption as aforesaid and, in case of any Securities selected for partial redemption as aforesaid, the principal amount thereof to be redeemed. 

The provisions of the two preceding paragraphs shall not apply with respect to any redemption affecting only a single Security, whether such
Security is to be redeemed in whole or in part. In the case of any such redemption in part, the unredeemed portion of the principal amount of the Security shall be in an authorized denomination (which shall not be less than the minimum
authorized denomination) for such Security. 
 For all purposes of this Indenture, unless the context otherwise requires, all provisions
relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be 

  
 -53- 

 
redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be redeemed. 

Section 11.4 Notice of Redemption. 

Notice of redemption shall be given in the manner provided in Section 1.6, not fewer than 30 nor more than 60 days prior to the Redemption

accrued interest, if any, on, all the Securities which are to be redeemed on that date.

shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of the same series and of like tenor, of any authorized denomination as 

  
 -55- 

 
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.

 SINKING
FUNDS 
 Section 12.1 Applicability of Article. 

The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of any series except as otherwise
specified as contemplated by Section 3.1 for such Securities. 
 The minimum amount of any sinking fund payment provided for by the
terms of any Securities 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 such Securities is herein referred to as an “optional sinking fund
payment.” If provided for by the terms of any Securities, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 12.2. Each sinking fund payment shall be applied to the redemption of Securities
as provided for by the terms of such Securities. 
 Section 12.2 Satisfaction of Sinking Fund Payments with Securities. 

The Company (1) may deliver Outstanding Securities of a series (other than any previously called for redemption) and (2) may apply as
a credit Securities of a series which have been 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 sinking fund payment with respect to any Securities of such series required to be made pursuant to the terms of such Securities as and to the extent provided for by the terms of such Securities;
provided that the Securities to be so credited have not been previously so credited. The Securities to be so credited shall be received and credited for such purpose by the Trustee at the Redemption Price, as specified in the Securities
so to be redeemed, for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly. 

Section 12.3 Redemption of Securities for Sinking Fund. 

Not fewer than 60 days prior to each sinking fund payment date for any Securities, the Company will deliver to the Trustee an Officers’
Certificate specifying the amount of the next ensuing sinking fund payment for such Securities pursuant to the terms of such Securities, 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 pursuant to Section 12.2 and will also deliver to the Trustee any Securities to be so delivered. Not fewer than 30 days prior to each such sinking fund payment date, the Trustee
shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 11.3 and cause notice of the redemption 

  
 -56- 

 
thereof to be given in the name of and at the expense of the Company in the manner provided in Section 11.4. Such notice having been duly given, the redemption of such Securities shall
be made upon the terms and in the manner stated in Sections 11.6 and 11.7.

The Company may elect, at its option at any time, to have Section 13.2 or Section 13.3 applied to any Securities or any series of
Securities, as the case may be, designated pursuant to Section 3.1 as being defeasible pursuant to such Section 13.2 or 13.3, in accordance with any applicable requirements provided pursuant to Section 3.1 and upon compliance with the
conditions set forth below in this Article. Any such election shall be evidenced by a Board Resolution or in another manner specified as contemplated by Section 3.1 for such Securities. 

Section 13.2 Defeasance and Discharge. 

Upon the Company’s exercise of its option (if any) to have this Section applied to any Securities or any series of Securities, as the
case may be, the Company shall be deemed to have been discharged from its obligations, and the provisions of Article 15 shall cease to be effective, with respect to such Securities as provided in this Section on and after the date the
conditions set forth in Section 13.4 are satisfied (hereinafter called “Defeasance”). For this purpose, such Defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by
such Securities 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), subject to the following which shall survive until otherwise terminated or discharged hereunder: 
 (1) the rights of
Holders of such Securities to receive, solely from the trust fund described in Section 13.4 and as more fully set forth in such Section, payments in respect of the principal of and any premium and interest on such Securities when payments are
due, 
 (2) the Company’s obligations with respect to such Securities under Sections 3.4, 3.5, 3.6, 10.2 and 10.3,
and, if applicable, Article 14,

may be, 
 (1) the Company shall be released from any covenants provided pursuant to Sections 3.1(20) or 9.1(2) for the
benefit of the Holders of such Securities, 
 (2) the occurrence of any event specified in Sections 5.1(4) (with
respect to any such covenants provided pursuant to Section 3.1(20) or 9.1(2)) and the occurrence of any Event of Default specified pursuant to Section 3.1, shall be deemed not to be or result in an Event of Default, and 

(3) the provisions of Article 15 shall cease to be effective, 

in each case with respect to such Securities or series of Securities as provided in this Section on and after the date the conditions set forth in
Section 13.4 are satisfied (hereinafter called “Covenant Defeasance”). For this purpose, such Covenant Defeasance means that, with respect to such Securities, the Company may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such specified Section (to the extent so specified in the case of Section 5.1(4) and the occurrence of any Event of Default specified pursuant to Section 3.1) or
Article 15, whether directly or indirectly by reason of any reference elsewhere herein to any such Section or Article or by reason of any reference in any such Section or Article to any other provision herein or in any other document, but the
remainder of this Indenture and such Securities shall be unaffected thereby.

The following shall be the conditions to the application of Section 13.2 or Section 13.3 to any Securities or any series of

thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or any such other qualifying trustee) to pay and discharge, the principal of and any premium and interest on such Securities on the respective Stated
Maturities, in accordance with the terms of this Indenture and such Securities. 
 (2) In the event of an election to have
Section 13.2 apply to any Securities or any series of Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of Counsel stating that

(B) since the date of this instrument, there has been a change in the applicable Federal income tax law,

such Securities will not recognize gain or loss for Federal income tax purposes as a result of the deposit, Defeasance and discharge to be effected with respect to such Securities and will be subject to Federal income tax on the same amount, in the
same manner and at the same times as would be the case if such deposit, Defeasance and discharge were not to occur. 
 (3)
In the event of an election to have Section 13.3 apply to any Securities or any series of Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such Securities
will not recognize gain or loss for Federal income tax purposes as a result of the deposit and Covenant Defeasance to be 

  
 -59- 

 
effected with respect to such Securities and will be subject to Federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit and Covenant
Defeasance were not to occur. 
 (4) The Company shall have delivered to the Trustee an Officers’ Certificate to the
effect that neither such Securities nor any other Securities of the same series, if then listed on any securities exchange, will be delisted as a result of such deposit. 

(5) No event which is, or after notice or lapse of time or both would become, an Event of Default with respect to such
Securities or any other Securities shall have occurred and be continuing at the time of such deposit or, with regard to any such event specified in Sections 5.1(5) and (6), at any time on or prior to the 90th day after the date of such deposit
(it being understood that this condition shall not be deemed satisfied until after such 90th day). 
 (6) Such Defeasance or
Covenant Defeasance shall not cause the Trustee to have a conflicting interest within the meaning of the Trust Indenture Act (assuming all Securities are in default within the meaning of such Act). 

(7) Such Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, this
Indenture or any other agreement or instrument to which the Company is a party or by which it is bound. 
 (8) Such
Defeasance or Covenant Defeasance shall not result in the trust arising from such deposit constituting an investment company within the meaning of the Investment Company Act unless such trust shall be registered under such Act or exempt from
registration thereunder. 
 (9) At the time of such deposit, 

(A) no default in the payment of any principal of or premium or interest on any Senior Debt shall have occurred and be
continuing, 
 (B) no event of default with respect to any Senior Debt shall have resulted in such Senior Debt becoming, and
continuing to be, due and payable prior to the date on which it would otherwise have become due and payable (unless payment of such Senior Debt has been made or duly provided for), and 

(C) no other event of default with respect to any Senior Debt shall have occurred and be continuing permitting (after notice
or lapse of time or both) the holders of such Senior Debt (or a trustee on behalf of such holders) to declare such Senior Debt due and payable prior to the date on which it would otherwise have become due and payable. 

  
 -60- 

 (10) The Company shall have delivered to the Trustee an Officers’
Certificate and an Opinion of Counsel, each stating that all conditions precedent with respect to such Defeasance or Covenant Defeasance have been complied with. 

Section 13.5 Deposited Money, U.S. Government Obligations and Foreign Government Obligations to be Held in Trust; Miscellaneous Provisions. 

Subject to the provisions of the last paragraph of Section 10.3, all money, U.S. Government Obligations and Foreign Government Obligations
(including the proceeds thereof) deposited with the Trustee or other qualifying trustee (solely for purposes of this Section and Section 13.6, the Trustee and any such other trustee are referred to collectively as the “Trustee”)
pursuant to Section 13.4 in respect of any Securities 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 such 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 any premium and interest, but money so held in trust need
not be segregated from other funds except to the extent required by law. Money, U.S. Government Obligations and Foreign Government Obligations so held in trust shall not be subject to the provisions of Article 15. 

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 or Foreign Government Obligations deposited pursuant to Section 13.4 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
Outstanding Securities. 
 Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from
time to time upon Company Request any money, U.S. Government Obligations or Foreign Government Obligations held by it as provided in Section 13.4 with respect to any Securities 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 to effect the Defeasance or Covenant Defeasance, as the case may
be, with respect to such Securities. 
 Section 13.6 Reinstatement. 

If the Trustee or the Paying Agent is unable to apply any money in accordance with this Article with respect to any Securities by reason of any
order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations under this Indenture and such Securities from which the Company has been discharged or released pursuant
to Section 13.2 or 13.3 shall be revived and reinstated as though no deposit had occurred pursuant to this Article with respect to such Securities, until such time as the Trustee or Paying Agent is permitted to apply all money held in trust
pursuant to Section 13.5 with respect to such Securities in accordance with this Article; provided, however, that if the Company makes any payment of principal of or any premium or interest on any such Security following such

  
 -61- 

 
reinstatement of its obligations, the Company shall be subrogated to the rights (if any) of the Holders of such Securities to receive such payment from the money so held in trust. 

ARTICLE 14 
 CONVERSION
OF SECURITIES 
 Section 14.1 Conversion. 

The terms of any conversion provision that shall be applicable to the Securities of any series shall be set forth in one or more indentures
supplemental hereto for the Securities of such series. 
 ARTICLE 15 

SUBORDINATION OF SECURITIES 
 Section
15.1 Agreement of Subordination. 
 Except as otherwise provided in a supplemental indenture or pursuant to Section 3.1, the Company
covenants and agrees, and each Holder of Securities issued hereunder by its acceptance thereof likewise covenants and agrees, that all Securities shall be issued subject to the provisions of this Article 15; and each Person holding any
Security, whether upon original issue or upon transfer, assignment or exchange thereof, accepts and agrees to be bound by such provisions. 

The payment of the principal of, premium, if any, and interest on all Securities (including, but not limited to, the redemption price with
respect to the Securities called for redemption in accordance with Article 11 as provided in the Indenture) issued hereunder shall, to the extent and in the manner hereinafter set forth, be subordinated and subject in right of payment to the
prior payment in full of all Senior Debt, whether outstanding at the date of this Indenture or thereafter incurred. 
 No provision of this
Article 15 shall prevent the occurrence of any default or Event of Default hereunder. 
 Section 15.2 Payments to Holders. 

No payment shall be made with respect to the principal of, or premium, if any, or interest on the Securities (including, but not limited to,
the redemption price with respect to the Securities to be called for redemption in accordance with Article 11 as provided in the Indenture), except payments and distributions made by the Trustee as permitted by the first or second paragraph of
Section 15.5, if: 
 (i) a default in the payment of principal, premium, if any, interest, rent or other obligations
due on any Senior Debt occurs and is continuing (or, in the case of Senior Debt for which there is a period of grace, in the event of 

  
 -62- 

 
such a default that continues beyond the period of grace, if any, specified in the instrument or lease evidencing such Senior Debt) (a “Payment Default”), unless and until such default
shall have been cured or waived or shall have ceased to exist; or 
 (ii) a default, other than a Payment Default, on any
Designated Senior Debt occurs and is continuing that then permits holders of such Designated Senior Debt to accelerate its maturity and the Trustee receives a notice of the default (a “Payment Blockage Notice”) from a holder of Designated
Senior Debt, a Representative of Designated Senior Debt or the Company (a “Non-Payment Default”). 
 If the Trustee receives any
Payment Blockage Notice pursuant to clause (ii) above, no subsequent Payment Blockage Notice shall be effective for purposes of this Section unless and until at least 365 days shall have elapsed since the initial effectiveness of the
immediately prior Payment Blockage Notice. No Non-Payment Default that existed or was continuing on the date of delivery of any Payment Blockage Notice to the Trustee shall be, or be made, the basis for a subsequent Payment Blockage Notice.

 The Company may and shall resume payments on and distributions in respect of the Securities upon the earlier of: 

(2) in the case of any Payment Default, the date upon which the Payment Default is cured or waived or ceases to exist, or 

(3) in the case of a Non-Payment Default, the earlier of (a) the date upon which such Non-Payment Default is cured,
waived or ceases to exist or (b) 179 days after the date on which the applicable Payment Blockage Notice is received by the Trustee, 
 unless this
Article 15 otherwise prohibits the payment or distribution at such time. 
 Upon any payment or distribution of assets of the Company
of any kind or character, whether in cash, property or securities, to creditors upon any dissolution or winding-up or liquidation or reorganization of the Company, whether voluntary or involuntary or in bankruptcy, insolvency, reorganization,
liquidation, receivership or other proceedings, or upon an assignment for the benefit of creditors or any marshalling of the assets and liabilities of the Company, or otherwise, all amounts due or to become due upon all Senior Debt shall first be
paid in full in cash or other payment satisfactory to the holders of such Senior Debt, or payment thereof in accordance with its terms provided for in cash or other payment satisfactory to the holders of such Senior Debt, before any payment is made
on account of the principal of, premium, if any, or interest on the Securities (except payments made pursuant to Article 4 from monies deposited with the Trustee pursuant thereto prior to commencement of proceedings for such dissolution,
winding-up, liquidation, reorganization, assignment for the benefit of creditors or the marshalling of assets and liabilities of the Company); and upon any such dissolution, winding-up, liquidation, reorganization, assignment for the benefit of
creditors or marshalling of assets and liabilities of the Company or bankruptcy, insolvency, 

  
 -63- 

 
receivership or other proceeding, any payment by the Company, or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to which the Holders of
the Securities or the Trustee would be entitled, except for the provision of this Article 15, shall (except as aforesaid) be paid by the Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such
payment or distribution, or by the Holders of the Securities or by the Trustee under this Indenture if received by them or it, directly to the holders of Senior Debt (pro rata to such holders on the basis of the respective amounts of Senior Debt
held by such holders, or as otherwise required by law or a court order) or their Representative or Representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any Senior Debt may have been issued,
as their respective interests may appear, to the extent necessary to pay all Senior Debt in full, in cash or other payment satisfactory to the holders of such Senior Debt, after giving effect to any concurrent payment or distribution to or for the
holders of Senior Debt, before any payment or distribution or provision therefor is made to the Holders of the Securities or to the Trustee. 

For purposes of this Article 15, the words, “cash, property or securities” shall not be deemed to include shares of stock of
the Company as reorganized or readjusted, or securities of the Company or any other corporation provided for by a plan of reorganization or readjustment, the payment of which is subordinated at least to the extent provided in this Article 15
with respect to the Securities to the payment of all Senior Debt which may at the time be outstanding; provided that (i) the Senior Debt is assumed by the new corporation, if any, resulting from any reorganization or readjustment, and
(ii) the rights of the holders of Senior Debt (other than leases which are not assumed by the Company or the new corporation, as the case may be) are not, without the consent of such holders, altered by such reorganization or
readjustment. The consolidation of the Company with, or the merger of the Company into, another corporation or the liquidation or dissolution of the Company following the conveyance or transfer of its property as an entirety, or substantially
as an entirety, to another corporation upon the terms and conditions provided for in Article 8 shall not be deemed a dissolution, winding-up, liquidation or reorganization for the purposes of this Section 15.2 if such other corporation
shall, as a part of such consolidation, merger, conveyance or transfer, comply with the conditions stated in Article 8. 
 In the event
of the acceleration of the Securities because of an Event of Default, no payment or distribution shall be made to the Trustee or any Holder of Securities in respect of the principal of, premium, if any, or interest on the Securities (including, but
not limited to, the redemption price with respect to the Securities called for redemption in accordance with Article 11 as provided in the Indenture), except payments and distributions made by the Trustee as permitted by the first or second
paragraph of Section 15.5, until all Senior Debt has been paid in full in cash or other payment satisfactory to the holders of Senior Debt or such acceleration is rescinded in accordance with the terms of this Indenture. If payment of the
Securities is accelerated because of an Event of Default, the Company shall promptly notify holders of Senior Debt of the acceleration. 

In the event that, notwithstanding the foregoing provisions, any payment or distribution of assets of the Company of any kind or character,
whether in cash, property or securities (including, without limitation, by way of setoff or otherwise), prohibited by the foregoing, shall be received by 

  
 -64- 

 
the Trustee or the Holders of the Securities before all Senior Debt is paid in full in cash or other payment satisfactory to the holders of such Senior Debt, or provision is made for such payment
thereof in accordance with its terms in cash or other payment satisfactory to the holders of such Senior Debt, such payment or distribution shall be held in trust for the benefit of and shall be paid over or delivered to the holders of Senior Debt
or their Representative or Representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any Senior Debt may have been issued, as their respective interests may appear, as calculated by the Company,
for application to the payment of all Senior Debt remaining unpaid to the extent necessary to pay all Senior Debt in full in cash or other payment satisfactory to the holders of such Senior Debt, after giving effect to any concurrent payment or
distribution to or for the holders of such Senior Debt. 
 Nothing in this Section 15.2 shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 6.7. This Section 15.2 shall be subject to the further provisions of Section 15.5. 
 Section
15.3 Subrogation of Securities. 
 Subject to the payment in full of all Senior Debt, the rights of the Holders of the Securities shall
be subrogated to the extent of the payments or distributions made to the holders of such Senior Debt pursuant to the provisions of this Article 15 (equally and ratably with the holders of all indebtedness of the Company which by its express
terms is subordinated to other indebtedness of the Company to substantially the same extent as the Securities are subordinated and is entitled to like rights of subrogation) to the rights of the holders of Senior Debt to receive payments or
distributions of cash, property or securities of the Company applicable to the Senior Debt until the principal, premium, if any, and interest on the Securities shall be paid in full; and, for the purposes of such subrogation, no payments or
distributions to the holders of the Senior Debt of any cash, property or securities to which the Holders of the Securities or the Trustee would be entitled except for the provisions of this Article 15, and no payment over pursuant to the
provisions of this Article 15, to or for the benefit of the holders of Senior Debt by Holders of the Securities or the Trustee, shall, as between the Company, its creditors other than holders of Senior Debt, and the Holders of the Securities,
be deemed to be a payment by the Company to or on account of the Senior Debt; and no payments or distributions of cash, property or securities to or for the benefit of the Holders of the Securities pursuant to the subrogation provisions of this
Article 15, which would otherwise have been paid to the holders of Senior Debt shall be deemed to be a payment by the Company to or for the account of the Securities. It is understood that the provisions of this Article 15 are and are
intended solely for the purposes of defining the relative rights of the Holders of the Securities, on the one hand, and the holders of the Senior Debt, on the other hand. 

Nothing contained in this Article 15 or elsewhere in this Indenture or in the Securities is intended to or shall impair, as among the
Company, its creditors other than the holders of Senior Debt, and the Holders of the Securities, the obligation of the Company, which is absolute and unconditional, to pay to the Holders of the Securities the principal of (and premium, if any) and
interest on the Securities as and when the same shall become due and payable in accordance with their terms, or is intended to or shall affect the relative rights of the Holders of the Securities and creditors of the Company other than the holders
of the Senior Debt, nor shall anything herein or 

  
 -65- 

 
therein prevent the Trustee or the Holder of any Security from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any,
under this Article 15 of the holders of Senior Debt in respect of cash, property or securities of the Company received upon the exercise of any such remedy. 

Upon any payment or distribution of assets of the Company referred to in this Article 15, the Trustee, subject to the provisions of
Section 6.1, and the Holders of the Securities shall be entitled to rely upon any order or decree made by any court of competent jurisdiction in which such bankruptcy, dissolution, winding-up, liquidation or reorganization proceedings are
pending, or a certificate of the receiver, trustee in bankruptcy, liquidating trustee, agent or other person making such payment or distribution, delivered to the Trustee or to the Holders of the Securities, for the purpose of ascertaining the
persons entitled to participate in such distribution, the holders of the Senior Debt and other indebtedness of the Company, the amount thereof or payable thereon and all other facts pertinent thereto or to this Article 15. 

Section 15.4 Authorization to Effect Subordination. 

Each Holder of a Security by the holder’s acceptance thereof authorizes and directs the Trustee on the holder’s behalf to take such
action as may be necessary or appropriate to effectuate the subordination as provided in this Article 15 and appoints the Trustee to act as the holder’s attorney-in-fact for any and all such purposes. If the Trustee does not file a
proper proof of claim or proof of debt in the form required in any proceeding referred to in Section 5.4 hereof at least 30 days before the expiration of the time to file such claim, the holders of any Senior Debt or their representatives are
hereby authorized to file an appropriate claim for and on behalf of the Holders of the Securities. 
 Section 15.5 Notice to Trustee. 

The Company shall give prompt written notice in the form of an Officers’ Certificate to a Responsible Officer of the Trustee and to any
Paying Agent of any fact known to the Company which would prohibit the making of any payment of monies to or by the Trustee or any Paying Agent in respect of the Securities pursuant to the provisions of this Article 15. Notwithstanding the
provisions of this Article 15 or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts which would prohibit the making of any payment of monies to or by the Trustee in respect of
the Securities pursuant to the provisions of this Article 15, unless and until a Responsible Officer of the Trustee shall have received written notice thereof at the Corporate Trust Office from the Company (in the form of an Officers’
Certificate) or a Representative or a holder or holders of Senior Debt or from any trustee therefor; and before the receipt of any such written notice, the Trustee, subject to the provisions of Section 6.1, shall be entitled in all respects to
assume that no such facts exist; provided that if on a date not fewer than two Business Days prior to the date upon which by the terms hereof any such monies may become payable for any purpose (including, without limitation, the payment of
the principal of, or premium, if any, or interest on any Security) the Trustee shall not have received, with respect to such monies, the notice provided for in this Section 15.5, then, anything herein contained to the contrary

  
 -66- 

 
notwithstanding, the Trustee shall have full power and authority to receive such monies and to apply the same to the purpose for which they were received, and shall not be affected by any notice
to the contrary which may be received by it on or after such prior date. 
 Notwithstanding anything in this Article 15 to the
contrary, nothing shall prevent any payment by the Trustee to the Holders of monies deposited with it pursuant to Section 4.1, and any such payment shall not be subject to the provisions of Section 15.1 or 15.2. 

The Trustee, subject to the provisions of Section 6.1, shall be entitled to rely on the delivery to it of a written notice by a
Representative or a person representing himself to be a holder of Senior Debt (or a trustee on behalf of such holder) to establish that such notice has been given by a Representative or a holder of Senior Debt or a trustee on behalf of any such
holder or holders. The Trustee shall not be required to make any payment or distribution to or on behalf of a holder of Senior Debt pursuant to this Article 15 unless it has received satisfactory evidence as to the amount of Senior Debt
held by such person, the extent to which such person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such person under this Article 15. 

Section 15.6 Trustee’s Relation to Senior Debt. 

The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article 15 in respect of any Senior Debt at
any time held by it, to the same extent as any other holder of Senior Debt, and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder. 

With respect to the holders of Senior Debt, the Trustee undertakes to perform or to observe only such of its covenants and obligations as are
specifically set forth in this Article 15, and no implied covenants or obligations with respect to the holders of Senior Debt shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty
to the holders of Senior Debt and, subject to the provisions of Section 6.1, the Trustee shall not be liable to any holder of Senior Debt (i) for any failure to make any payments or distributions to such holders or (ii) if it shall
pay over or deliver to Holders of Securities, the Company or any other Person money or assets to which any holder of Senior Debt shall be entitled by virtue of this Article 15 or otherwise. 

Section 15.7 No Impairment of Subordination. 

No right of any present or future holder of any Senior Debt to enforce subordination as herein provided shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by the Company, the Trustee or any Holder of Securities with the terms,
provisions and covenants of this Indenture, regardless of any knowledge thereof which any such holder may have or otherwise be charged with. 

  
 -67- 

 Section 15.8 Certain Conversions/Exchanges Deemed Payment. 

For the purposes of this Article 15 only, (1) the issuance and delivery of junior securities upon conversion or exchange of Securities in
accordance with Article 14 or any supplemental indenture with respect to such series of securities or otherwise (except upon conversion of the Securities in accordance with their terms) shall not be deemed to constitute a payment or distribution on
account of the principal of (or premium, if any) or interest on Securities or on account of the purchase or other acquisition of Securities, and (2) the payment, issuance or delivery of cash (except in satisfaction of fractional shares upon
conversion, if applicable), property or securities (other than junior securities) upon conversion or exchange of a Security shall be deemed to constitute payment on account of the principal of such Security. For the purposes of this
Section 15.8, the term “junior securities” means (a) shares of any stock of any class of the Company, or (b) securities of the Company which are subordinated in right of payment to all Senior Debt which may be outstanding at
the time of issuance or delivery of such securities to substantially the same extent as, or to a greater extent than, the Securities are so subordinated as provided in this Article. Nothing contained in this Article 15 or elsewhere in this
Indenture or in the Securities is intended to or shall impair, as among the Company, its creditors other than holders of Senior Debt and the Holders of Securities, the right, which is absolute and unconditional, of the Holder of any Security to
convert such Security in accordance with Article 14. 
 Section 15.9 Article Applicable to Paying Agents. 

If at any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term
“Trustee” as used in this Article shall (unless the context otherwise requires) be construed as extending to and including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named in
this Article in addition to or in place of the Trustee; provided, however, that the first paragraph of Section 15.5 shall not apply to the Company or any Affiliate of the Company if the Company or such Affiliate acts as Paying
Agent. 
 The Trustee shall not be responsible for the actions or inactions of any other Paying Agents (including the Company if acting as
its own Paying Agent) and shall have no control of any funds held by such other Paying Agents. 
 Section 15.10 Senior Debt Entitled to Rely. 

The holders of Senior Debt (including, without limitation, Designated Senior Debt) shall have the right to rely upon this Article 15, and
no amendment or modification of the provisions contained herein shall diminish the rights of such holders unless such holders shall have agreed in writing thereto. 

Section 15.11 Reliance on Judicial Order or Certificate of Liquidating Agent. 

Upon any payment or distribution of assets of the Company referred to in this Article, the Trustee and the Holders shall be entitled to rely
upon any order or decree entered by any court of 

  
 -68- 

 
competent jurisdiction in which such dissolution, winding up, liquidation, reorganization, assignment for the benefit of creditors or marshalling of assets and liabilities of the Company or
bankruptcy, insolvency, receivership or other like proceeding is pending, or a certificate of the trustee in bankruptcy, liquidating trustee, custodian, receiver, assignee for the benefit of creditors, agent or other person making such payment or
distribution, delivered to the Trustee or to the Holders, for the purpose of ascertaining the persons entitled to participate in such payment or distribution, the holders of Senior Debt and other indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article. 
 Section 15.12 Trust
Monies Not Subordinated. 
 Notwithstanding anything contained herein to the contrary, payments from money, U.S. Government Obligations
and/or Foreign Government Obligations held in trust under Article 4 or Article 13 by the Trustee for the payment of the principal of, premium, if any, and interest on the Securities shall not be subordinated to the prior payment in full of
any Senior Debt of the Company or subject to the restrictions set forth in this Article 15, and none of the Holders shall be obligated to pay over any such amount to the Company or any holder of Senior Debt of the Company or any other creditor
of the Company.

instrument or instruments are delivered to the Trustee, and, where it is hereby expressly required, to the Company. If any Securities are denominated in coin or currency other than that of the United States, then for the purposes of determining
whether the Holders of the requisite principal amount of Securities have taken any action as herein described, the principal amount of such Securities shall be deemed to be that amount of United States dollars that could be obtained for such

proved by the affidavit of a witness to such execution or by the certificate of any 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 an officer of a corporation or a member of a partnership, on behalf of such corporation or partnership, 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 that the Trustee deems sufficient. 

(c) The ownership of Securities shall be proved by the Security Register. 

(d) If the Company shall solicit from the Holders any request, demand, authorization, direction, notice, consent, waiver or other action, the
Company may, at its option, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other action, but the Company shall have no obligation to do so.
Such record date shall be the later of 10 days prior to the first solicitation of such action or the date of the most recent list of Holders furnished to the Trustee pursuant to Section 7.01. If such a record date is fixed, such request,
demand, authorization, direction, notice, consent, waiver or other action may be given before or after the record date, but only the Holders of record at the close of business on the record date shall be deemed to be Holders for the purposes of
determining whether Holders of the requisite proportion of Securities outstanding have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other action, and for that purpose the Securities
outstanding shall be computed as of the record date; provided that no such authorization, agreement or consent by the Holders on the 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, and that no such authorization, agreement or consent may be amended, withdrawn or revoked once given by a Holder, unless the Company shall provide for such amendment, withdrawal or
revocation in conjunction with such solicitation of authorizations, agreements or consents or unless and to the extent required by applicable law. 

(e) Any request, demand, authorization, direction, notice, consent, waiver or other action by the Holder of any Security shall bind 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 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. 
 SECTION 1.05 Notices, etc., to Trustee and Company. Any request, demand, authorization,
direction, notice, consent, waiver or Act of Securityholders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with:

furnished or filed in writing to or with the Trustee at its Corporate Trust Office, Attention: Corporate Trust Services, Administrator for Ply-Gem Holdings, Inc.; or

 11 

 
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 instrument, Attention: General
Counsel, or at the address last furnished in writing to the Trustee by the Company. 
 SECTION 1.06 Notices to Securityholders;
Waiver. Where this Indenture or any Security provides for notice to Securityholders of any event, such notice shall be sufficiently given (unless otherwise herein or in such Security expressly provided) if in writing and mailed, first-class
postage prepaid, to each Securityholder 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 Securityholders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Securityholder shall affect the sufficiency of such notice with respect to other
Securityholders. 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 by Securityholders 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 as a result of a strike, work stoppage or otherwise, it shall be impractical to
mail notice of any event to any Securityholder when such notice is required to be given pursuant to any provision of this Indenture, then any method of notification as shall be satisfactory to the Trustee and the Company shall be deemed to be a
sufficient giving of such notice. 
 SECTION 1.07 Conflict with Trust Indenture Act. If and to the extent that any provision hereof
limits, qualifies or conflicts with the duties imposed by, or with another provision (an “incorporated provision”) included in this Indenture by operation of, any of Sections 310 to 318, inclusive, of the Trust Indenture Act,
such imposed duties or incorporated provision shall control. 
 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.

other than the parties hereto and their successors hereunder, any Authenticating Agent or Paying Agent, the Security Registrar and the Holders of Securities (or such of them as may be affected thereby), any benefit or any legal or equitable right,
remedy or claim under this Indenture.

counterparts, each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same instrument. The exchange of copies of this Indenture and of signature pages by facsimile or PDF

be deemed to be their original signatures for all purposes. 
 SECTION 1.14 Judgment Currency. The Company agrees, to the fullest
extent that it may effectively do so under applicable law, that (a) if for the purpose of obtaining judgment in any court it is necessary to convert the sum due in respect of the principal of, or premium or interest, if any, on the Securities of any
series (the “Required Currency”) into a currency in which a judgment will be rendered (the “Judgment Currency”), the rate of exchange used shall be the rate at which in accordance with normal banking procedures the
Trustee could purchase in the City of New York the Required Currency with the Judgment Currency on the New York Banking Day preceding that on which a final unappealable judgment is given and (b) its obligations under this Indenture to make
payments in the Required Currency (i) shall not be discharged or satisfied by any tender, or any recovery pursuant to any judgment (whether or not entered in accordance with subsection (a)), in any currency other than the Required Currency,
except to the extent that such tender or recovery shall result in the actual receipt, by the payee, of the full amount of the Required Currency expressed to be payable in respect of such payments, (ii) shall be enforceable as an alternative or
additional cause of action for the purpose of recovering in the Required Currency the amount, if any, by which such actual receipt shall fall short of the full amount of the Required Currency so expressed to be payable and (iii) shall not be
affected by judgment being obtained for any other sum due under this Indenture. For purposes of the foregoing, “New York Banking Day” means any day except a Saturday, Sunday or a legal holiday in the City of New York or a day on
which banking institutions in the City of New York are authorized or required by law or executive order to close. 
 SECTION 1.15 Force
Majeure. In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without
limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and
hardware) services; it being understood that the Trustee shall use reasonable efforts that are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances. 

SECTION 1.16 Patriot Act. The parties hereto acknowledge that in accordance with Section 326 of the U.S.A. PATRIOT Act, the Trustee,
like all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify, and record information that identifies each person or legal entity that establishes a relationship or opens an
account with the Trustee. The parties to this Indenture agree that they will provide the Trustee with such information as it may request in order for the Trustee to satisfy the requirements of the U.S.A. PATRIOT Act.

 SECTION 2.04 Securities Issuable in the Form of a Global Security. (a) If the Company
shall establish pursuant to Sections 2.02 and 3.01 that the Securities of a particular series are to be issued in whole or in part in the form of one or more Global Securities, then the Company shall execute and the Trustee or its agent shall,
in accordance with Section 3.03 and the Company Order delivered to the Trustee or its agent thereunder, authenticate and deliver, such Global Security or Securities, which (i) shall represent, and shall be denominated in an amount equal to the
aggregate principal amount of, the Outstanding Securities of such series to be represented by such Global Security or Securities, or such portion thereof as the Company shall specify in a Company Order, (ii) shall be registered in the name of the
Depository for such Global Security or Securities or its nominee, (iii) shall be delivered by the Trustee or its agent to the Depository or pursuant to the Depository’s instruction and (iv) shall bear a legend substantially to the following
effect: “Unless this certificate is presented by an authorized representative of the Depository to Issuer or its agent for registration of transfer, exchange, or payment, and any certificate issued is registered in the name of the nominee of
the Depository or in such other name as is requested by an authorized representative of the Depository (and any payment is made to the nominee of the Depository or to such other entity as is requested by an authorized representative of the
Depository), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered owner hereof, the nominee of the Depository, has an interest herein.” 

(b) Notwithstanding any other provision of this Section 2.04 or of Section 3.05, and subject to the provisions of paragraph (c)
below, unless the terms of a Global Security expressly permit such Global Security to be exchanged in whole or in part for individual Securities, a Global Security may be transferred, in whole but not in part and in the manner provided in
Section 3.05, only to a nominee of the Depository for such Global Security, or to the Depository, or a successor Depository for such Global Security selected or approved by the Company, or to a nominee of such successor Depository. 

(c) (i) If at any time the Depository for a Global Security notifies the Company that it is unwilling or unable to continue as Depository for
such Global Security or if at any time the Depository for the Securities for such series shall no longer be eligible or in good standing under the Securities Exchange Act of 1934, as amended, or other applicable statute or regulation, the Company
shall appoint a successor Depository with respect to such Global Security. If a successor Depository for such Global Security is not appointed by the Company within 90 days after the Company receives such notice or becomes aware of such
ineligibility, the Company will execute, and the Trustee or its agent, upon receipt of a Company Request for the authentication and delivery of individual Securities of such series in exchange for such Global Security, will authenticate and deliver,
individual Securities of such series of like tenor and terms in an aggregate principal amount equal to the principal amount of the Global Security in exchange for such Global Security. 

(ii) The Company may at any time and in its sole discretion determine that the Securities of any series or portion thereof issued or issuable
in the form of one or more Global Securities shall no longer be represented by such Global Security or Securities. In such event the Company will execute, and the Trustee, upon receipt of a Company Request for the authentication and delivery of
individual Securities of such series in exchange in whole or in part for such Global Security, will authenticate and deliver individual Securities of such series of like tenor and terms in definitive form in an aggregate principal amount equal to
the principal amount of such Global Security or Securities representing such series or portion thereof in exchange for such Global Security or Securities. 

  
 15 

 (iii) If specified by the Company pursuant to Sections 2.02 and 3.02 with respect to
Securities issued or issuable in the form of a Global Security, the Depository for such Global Security may surrender such Global Security in exchange in whole or in part for individual Securities of such series of like tenor and terms in definitive
form on such terms as are acceptable to the Company and such Depository. Thereupon the Company shall execute, and the Trustee or its agent shall authenticate and deliver, without service charge, (1) to each Person specified by such Depository a new
Security or Securities of the same series of like tenor and terms and of any authorized denomination as requested by such Person in aggregate principal amount equal to and in exchange for such Person’s beneficial interest as specified by such
Depository in the Global Security; and (2) to such Depository a new Global Security of like tenor and terms and in an authorized denomination equal to the difference, if any, between the principal amount of the surrendered Global Security and the
aggregate principal amount of Securities delivered to Holders thereof. 
 (iv) In any exchange provided for in any of the preceding three
paragraphs, the Company will execute and the Trustee or its agent will authenticate and deliver individual Securities in definitive registered form in authorized denominations. Upon the exchange of the entire principal amount of a Global Security
for individual Securities, such Global Security shall be canceled by the Trustee or its agent. Except as provided in the preceding paragraph, Securities issued in exchange for a Global Security pursuant to this Section shall be registered in such
names and in such authorized denominations as the Depository for such Global Security, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee or the Security Registrar. The Trustee or the Security
Registrar shall deliver at its Corporate Trust Office such Securities to the Persons in whose names such Securities are so registered.

and except for any Securities that, pursuant to Section 3.03, are deemed never to have been authenticated and delivered hereunder);

(15) provisions, if any, with regard to the appointment by the Company of an Authenticating Agent in one or more places other

 (18)
any covenant solely for the benefit of the Securities of such series and any additions, deletions or other changes to the provisions of Article VIII, Article X or Section 1.01 or any definitions relating to such Article that would otherwise be

 (19) if Section 4.03 of this Indenture shall not be applicable to the

(21) any other terms of such series, including, without limitations, any restrictions on transfer related thereto. 

all upon such terms as may be determined in or pursuant to such Board Resolution or indenture supplemental hereto with respect to such series. 

The form of the Securities of each series shall be established pursuant to the provisions of this Indenture in or pursuant to the Board
Resolution or in the indenture supplemental hereto creating such series. The Securities of each series shall be distinguished from the Securities of each other series in such manner, reasonably satisfactory to the Trustee, as the Board of
Directors may determine. 

  
 18 

 Unless otherwise provided with respect to Securities of a particular series, the Securities of
any series may only be issuable in registered form, without coupons. 
 Any terms or provisions in respect of the Securities of any series
issued under this Indenture may be determined pursuant to this Section by providing for the method by which such terms or provisions shall be determined. 

SECTION 3.02 Denominations. The Securities of each series shall be issuable in such denominations and currency as shall be
provided in the provisions of this Indenture or in or pursuant to the Board Resolution or the indenture supplemental hereto creating such series. In the absence of any such provisions with respect to the Securities of any series, the Securities
of that series shall be issuable only in fully registered form in denominations of $2,000 and integral multiples of $1,000 in excess thereof. 

SECTION 3.03 Execution, Authentication and Delivery and Dating. The Securities shall be executed on behalf of the Company by its
Chief Executive Officer, its Chief Financial Officer, its Chief Operating Officer, one of its Vice Presidents or its Treasurer or any Assistant Treasurer and 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. 
 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 executed by the Company to the Trustee for authentication; and the Trustee shall, upon Company Order, authenticate and deliver such Securities as in this Indenture provided and not otherwise. 

Prior to any such authentication and delivery, the Trustee shall be provided with the Officers’ Certificate and Opinion of Counsel
required to be furnished to the Trustee pursuant to Section 1.02, and the Board Resolution and any certificate relating to the issuance of the series of Securities required to be furnished pursuant to Section 2.02, and Opinion of Counsel
substantially to the effect that: 
 (1) all instruments furnished to the Trustee conform to the requirements of the
Indenture and constitute sufficient authority hereunder for the Trustee to authenticate and deliver such Securities; 
 (2)
the form and terms of such Securities have been established in conformity with the provisions of this Indenture; 
 (3) all
laws and requirements with respect to the execution and delivery by the Company of such Securities have been complied with, the Company has the corporate power to issue such Securities and such Securities have been duly authorized and delivered by
the Company and, assuming due authentication and delivery by the Trustee, constitute legal, valid and binding obligations of the Company enforceable in accordance 

  
 19 

 
with their terms (subject, as to enforcement of remedies, to applicable bankruptcy, reorganization, insolvency, moratorium or other laws and legal principles affecting creditors’ rights
generally from time to time in effect and to general equitable principles, whether applied in an action at law or in equity) and entitled to the benefits of this Indenture, equally and ratably with all other Securities, if any, of such series
Outstanding; 
 (4) when applicable, the Indenture is qualified under the Trust Indenture Act; and 

(5) such other matters as the Trustee may reasonably request; 

and, if the authentication and delivery relates to a new series of Securities created by an indenture supplemental hereto, also stating that all laws and
requirements with respect to the form and execution by the Company of the supplemental indenture with respect to that series of Securities have been complied with, the Company has corporate power to execute and deliver any such supplemental
indenture and has taken all necessary corporate action for those purposes and any such supplemental indenture has been duly executed and delivered and constitutes the legal, valid and binding obligation of the Company enforceable in accordance with
its terms (subject, as to enforcement of remedies, to applicable bankruptcy, reorganization, insolvency, moratorium or other laws and legal principles affecting creditors’ rights generally from time to time in effect and to general equitable
principles, whether applied in an action at law or in equity). 
 The Trustee shall not be required to authenticate such Securities if the
issue thereof will adversely affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture. 
 Unless
otherwise provided in the form of Security for any series, all Securities shall be dated the date of their 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. Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 3.09, for all purposes of this Indenture such Security shall be
deemed never to have been authenticated and delivered hereunder and shall never be 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, and, upon receipt of the documents required by Section 3.03, together with a Company Order, the Trustee shall
authenticate and deliver, temporary Securities which are printed, lithographed, typewritten 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 officers executing such Securities may determine, as evidenced by their execution of such Securities. 

If temporary Securities of any series are issued, the Company will cause definitive Securities of such series to be prepared without
unreasonable delay. After the 

  
 20 

 
preparation of definitive Securities, 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, without charge to the Holder; and upon surrender for cancellation of any one or more temporary Securities the Company shall execute and the Trustee shall authenticate and deliver
in exchange therefor a like principal amount of definitive Securities of such series of authorized denominations and of like tenor and terms. Until so exchanged the temporary Securities of such series shall in all respects be entitled to the same
benefits under this Indenture as definitive Securities of such series. 
 SECTION 3.05 Registration, Transfer and Exchange. The
Company shall keep or cause to be kept a register or registers (herein sometimes 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, or of Securities of a particular series, and of transfers of Securities or of Securities of such series. Any such register shall be in written form or in any other form capable of being converted into written form within
a reasonable time. At all reasonable times the information contained in such register or registers shall be available for inspection by the Trustee at the office or agency to be maintained by the Company as provided in Section 10.02. There
shall be only one Security Register per series of Securities. 
 Subject to Section 2.04, upon surrender for registration of transfer
of any Security of any series at the office or agency of the Company maintained for such purpose in a Place of Payment, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Securities of such series of any authorized denominations, of a like aggregate principal amount and Stated Maturity and of like tenor and terms. 

Subject to Section 2.04, at the option of the Holder, Securities of any series may be exchanged for other Securities of such series of
any authorized denominations, of a like aggregate principal amount and Stated Maturity and of like tenor and terms, 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 deliver, the Securities that the Securityholder making the exchange is entitled to receive. 

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations 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 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 Trustee duly executed, by the Holder thereof or his attorney duly authorized in writing. 

Unless otherwise provided in the Security to be registered for transfer or exchanged, no service charge shall be made on any Securityholder
for any registration of transfer or exchange of Securities, but the Company may (unless otherwise provided in such Security) 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. 

  
 21 

 The Company shall not be required (i) to issue, register the transfer of or exchange any Security
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 such series selected for redemption under Section 11.03 and ending at the close of business on
the date of such mailing, or (ii) to register the transfer of or exchange any Security so selected for redemption in whole or in part. 

None of the Company, the Trustee, any agent of the Trustee, any Paying Agent or the Security Registrar will have any responsibility or
liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 

SECTION 3.06 Mutilated, Destroyed, Lost and Stolen Securities. If (i) any mutilated Security is surrendered to the Trustee, or the
Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security, and (ii) there is delivered to the Company and the Trustee such security or indemnity as may be required by them to save each 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 written request the Trustee shall authenticate and deliver, in exchange for
or in lieu of any such mutilated, destroyed, lost or stolen Security, a new Security of like tenor, series, Stated Maturity and principal amount, 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 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 the same 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. Unless otherwise provided with respect to such Security pursuant to
Section 3.01, interest on any Security that is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid 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. 
 Any interest on any Security that 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 registered Holder on the relevant Regular Record Date by virtue of his

  
 22 

 
having been such Holder; and, except as hereinafter provided, such Defaulted Interest may be paid by the Company, at its election in each case, as provided in Clause (1) or Clause (2)
below: 
 (1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names any such
Securities (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 “Special Record Date”).
The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each such Security 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 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 Clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest that shall be not more than 15 nor 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 the Holder of each such Security 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 mailed as aforesaid, such Defaulted Interest shall be paid to the
Persons in whose names such Securities (or their respective Predecessor Securities) are registered 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 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 payment pursuant to this Clause, such manner of payment
shall be deemed practicable by the Trustee. 
 If any installment of interest the Stated Maturity of which is on or prior to the Redemption
Date for any Security called for redemption pursuant to Article XI is not paid or duly provided for on or prior to the Redemption Date in accordance with the foregoing provisions of this Section, such interest shall be payable as part of the
Redemption Price of such Securities. 
 Subject to the foregoing provisions of this Section, each Security delivered under this Indenture
upon registration or 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. The Company, the Trustee and any agent of the Company or the Trustee may treat the Person in
whose name any 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. 

  
 23 

 None of the Company, the Trustee, any Paying Agent or the Security Registrar will have any
responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership
interests. 
 SECTION 3.09 Cancellation. All Securities surrendered for payment, conversion, redemption, registration of
transfer, exchange or credit against a sinking fund shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and, if not already canceled, shall be promptly canceled 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 canceled by the Trustee. No Security
shall be authenticated in lieu of or in exchange for any Securities canceled as provided in this Section, except as expressly permitted by this Indenture. The Trustee shall dispose of all canceled Securities in accordance with its standard
procedures and deliver a certificate of such disposition to the Company upon its written request therefor. 
 SECTION 3.10 Computation of
Interest. Unless otherwise provided as contemplated in Section 3.01, interest on the Securities shall be calculated on the basis of a 360-day year of twelve 30-day months. 

SECTION 3.11 Delayed Issuance of Securities. Notwithstanding any contrary provision herein, if all Securities of a series are not to be
originally issued at one time, it shall not be necessary for the Company to deliver to the Trustee an Officers’ Certificate, Board Resolution, indenture supplemental hereto, opinion of counsel or Company Order otherwise required pursuant to
Sections 1.02, 2.02, 3.01 and 3.03 at or prior to the time of authentication of each Security of such series if such documents are delivered to the Trustee or its agent at or prior to the authentication upon original issuance of the first
Security of such series to be issued; provided that any subsequent request by the Company to the Trustee to authenticate Securities of such series upon original issuance shall constitute a representation and warranty by the Company that as of
the date of such request, the statements made in the Officers’ Certificate or other certificates delivered pursuant to Sections 1.02 and 2.02 shall be true and correct as if made on such date. 

A Company Order, Officers’ Certificate or Board Resolution or indenture supplemental hereto delivered by the Company to the Trustee in
the circumstances set forth in the preceding paragraph may provide that Securities that are the subject thereof will be authenticated and delivered by the Trustee or its agent on original issue from time to time in the aggregate principal amount, if
any, established for such series pursuant to such procedures reasonably acceptable to the Trustee as may be specified from time to time by Company Order upon the telephonic, electronic or written order of Persons designated in such Company Order,
Officers’ Certificate, indenture supplemental hereto or Board Resolution (any such telephonic or electronic instructions to be promptly confirmed in writing by such Persons) and that such Persons are authorized to determine, consistent with
such Company Order, Officers’ Certificate, indenture supplemental hereto or Board Resolution, such terms and conditions of said Securities as are specified in such Company Order, Officers’ Certificate, indenture supplemental hereto or
Board Resolution.

Satisfaction and Discharge 

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

(1) either 

(A) all Securities of that series theretofore authenticated and delivered (other than (i) Securities of such series that have
been destroyed, lost or stolen and that have been replaced or paid as provided in Section 3.06, and (ii) Securities of such series for whose payment money in the Required Currency 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 10.03) have been delivered to the Trustee canceled or for cancellation; or 

(B) all such Securities of that series not theretofore delivered to the Trustee canceled or for cancellation: 

(i) have become due and payable, or 

(ii) will become due and payable at their Stated Maturity within one year, or 

(iii) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice
of redemption by the Trustee in the name, and at the expense, of the Company, 
 and the Company, in the case of (i), (ii) or (iii) above, has irrevocably
deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose an amount in the Required Currency sufficient to pay and discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee
canceled or for cancellation, for principal (and premium, if any) and interest to the date of such deposit (in the case of Securities that have become due and payable), or to the Stated Maturity or Redemption Date, as the case may be; 

(2) the Company has paid or caused to be paid all other sums payable hereunder by the Company with respect to the Securities of
such series; and 
 (3) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel each
stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture with respect to the Securities of such series have been complied with.

respect to that series under Section 6.07 shall survive and the obligations of the Company and the Trustee under Sections 3.05, 3.06, 4.02, 10.02 and 10.03 shall survive such satisfaction and discharge.

 SECTION 4.02 Application of Trust Money. Subject to the provisions of the last
paragraph of Section 10.03, all money deposited with the Trustee pursuant to Section 4.01 or Section 4.03 shall be held in trust and applied by it, in accordance with the provisions of the series of Securities in respect of which it
was deposited 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 the Trustee; but such money need not be segregated from other funds except to the extent required by law. 

Anything herein to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request any
money or securities deposited with and held by it as provided in Section 4.03 and this Section 4.02 that, 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 to effect an equivalent satisfaction and discharge, Discharge (as defined below) or covenant defeasance, provided that the Trustee
shall not be required to liquidate any securities in order to comply with the provisions of this paragraph. 
 SECTION 4.03 Defeasance
Upon Deposit of Funds or Government Obligations. Unless pursuant to Section 3.01 provision is made that this Section shall not be applicable to the Securities of any series, at the Company’s option, either (a) the Company shall be
deemed to have been Discharged (as defined below) from its obligations with respect to any series of Securities after the applicable conditions set forth below have been satisfied or (b) the Company shall cease to be under any obligation to comply
with any term, provision or condition set forth in Section 10.05 and Article VIII (and any other Sections or covenants applicable to such Securities that are determined pursuant to Section 3.01 to be subject to this provision) and
Clause (4) of Section 5.01 of this Indenture (and any other Events of Default applicable to such Securities that are determined pursuant to Section 3.01 to be subject to this provision) shall be deemed not to be an Event of Default
with respect to any series of Securities at any time after the applicable conditions set forth below have been satisfied: 

(1) the Company shall have deposited or caused to be deposited irrevocably with the Trustee as trust funds, specifically
pledged as security for, and dedicated solely to, the benefit of the Holders of the Securities of such series, (i) money in an amount, or (ii) the equivalent in securities of the government that issued the currency in which the Securities are
denominated or government agencies backed by the full faith and credit of such government that through the payment of interest and principal in respect thereof in accordance with their terms will provide freely available funds on or prior to the due
date of any payment, money in an amount, or (iii) a combination of (i) and (ii), sufficient, in the opinion (with respect to (ii) and (iii)) of a nationally recognized firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee, to pay and discharge each installment of principal (including mandatory sinking fund payments) and any premium of, interest on and any repurchase or redemption obligations with respect to the outstanding Securities
of such series on the dates such installments of interest or principal or repurchase or redemption obligations are due (before such a deposit, if the Securities of such series are then redeemable or may be redeemed in the future pursuant to the
terms thereof, in either case at the option of the Company, the 

  
 26 

 
Company may give to the Trustee, in accordance with Section 11.02, a notice of its election to redeem all of the Securities of such series at a future date in accordance with Article XI);

 (2) no Event of Default or event (including such deposit) that with notice or lapse of time would become an Event of
Default with respect to the Securities of such series shall have occurred and be continuing on the date of such deposit (other than an Event of Default resulting from the borrowing of funds to be applied to such deposit); 

(3) the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that Holders of the Securities of such
series will not recognize income, gain or loss for Federal income tax purposes as a result of the Company’s exercise of its option under this Section 4.03 and will be subject to Federal income tax on the same amount and in the same manner
and at the same times as would have been the case if such option had not been exercised, and, in the case of Securities being Discharged, accompanied by a ruling to that effect from the Internal Revenue Service, unless, as set forth in such Opinion
of Counsel, there has been a change in the applicable federal income tax law since the date of this Indenture such that a ruling from the Internal Revenue Service is no longer required; 

(4) the Company shall have delivered to the Trustee an Officers’ Certificate stating that the deposit referred to in
paragraph (1) above was not made by the Company with the intent of preferring the Holders over other creditors of the Company or with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others; and 

(5) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel each stating that
all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture with respect to the Securities of such series have been complied with. 

“Discharged” means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by, and
obligations under, the Securities of such series and to have satisfied all the obligations under this Indenture relating to the Securities of such series (and the Trustee, on receipt of a Company Request and at the expense of the Company, shall
execute proper instruments acknowledging the same), except (A) the rights of Holders of Securities to receive, from the trust fund described in clause (1) above, payment of the principal and any premium of and any interest on such Securities
when such payments are due; (B) the Company’s obligations with respect to such Securities under Sections 3.05, 3.06, 4.02, 6.07, 10.02 and 10.03; (C) the Company’s right of redemption, if any, with respect to any Securities of such
series pursuant to Article XI, in which case the Company may redeem the Securities of such series in accordance with Article XI by complying with such Article and depositing with the Trustee, in accordance with Section 11.05, an amount of money
sufficient, together with all amounts held in trust pursuant to Section 4.02 with respect to Securities of such series, to pay the Redemption Price of all the Securities of such series to be redeemed; and (D) the rights, powers, trusts, duties
and immunities of the Trustee hereunder. A “Discharge” shall mean the meeting by the Company of the foregoing requirements. 

SECTION 4.04 Reinstatement. If the Trustee or Paying Agent is unable to apply any money or securities in accordance with
Section 4.02 of this Indenture, by reason of any legal proceeding or by reason of any order or judgment of any court or 

  
 27 

 
governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under this Indenture and the Securities shall be revived and reinstated as
though no deposit had occurred pursuant to Section 4.01 or 4.03 of this Indenture, as the case may be, until such time as the Trustee or Paying Agent is permitted to apply all such money or securities in accordance with Section 4.02 of
this Indenture; provided that, if the Company has made any payment of principal of or interest on any Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities
to receive such payment from the money or securities held by the Trustee or Paying Agent. 
 ARTICLE V 

Remedies

5.01 Events of Default. “Event of Default”, wherever used herein, means with respect to any series of Securities any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary
or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body), unless such event is either inapplicable to a particular series
or it is specifically deleted or modified in or pursuant to the indenture supplemental hereto or Board Resolution creating such series of Securities or in the form of Security for such series: 

(1) default in the payment of any interest upon any Security of that series when it becomes due and payable, and continuance of

 (4) default in the performance, or
breach, of any covenant or warranty of the Company in this Indenture in respect of the Securities of such series (other than a covenant or warranty in respect of the Securities of such series a default in the performance of which or the breach of
which is elsewhere in this Section specifically dealt with), all of such covenants and warranties in the Indenture that are not expressly stated to be for the benefit of a particular series of Securities being deemed in respect of the Securities of
all series for this purpose, and continuance of such default or breach for a period of 90 days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least
25% in aggregate principal amount of the Outstanding Securities of such series, a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder; or

 (5) the entry of an order for relief against the Company or any Material U.S. Subsidiary thereof under Title 11, United
States Code (the “Federal Bankruptcy Act”) by a court having jurisdiction in the premises or a decree or order by a court having jurisdiction in the premises adjudging the Company or any Material U.S. Subsidiary thereof a bankrupt
or insolvent under any other applicable Federal or State law, or the 

  
 28 

 
entry of a decree or order approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Company or any Material U.S. Subsidiary
thereof under the Federal Bankruptcy Act or any other applicable Federal or State law, or appointing a receiver, liquidator, assignee, trustee, sequestrator (or other similar official) of the Company or any Material U.S. Subsidiary thereof or of any
substantial part of its property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order unstayed and in effect for a period of 90 consecutive days; or 

(6) the consent by the Company or any Material U.S. Subsidiary thereof to the institution of bankruptcy or insolvency

to the appointment of a receiver, liquidator, assignee, trustee, sequestrator (or other similar official) of the Company or any Material U.S. Subsidiary thereof or of any substantial part of its property, or the making by it of an assignment for the
benefit of creditors, or the admission by it in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by the Company or any Material U.S. Subsidiary thereof in furtherance of any such action; 

(7) any other Event of Default provided in the indenture supplemental hereto or Board Resolution under which such series of
Securities is issued or in the form of Security for such series. 
 SECTION 5.02 Acceleration of Maturity; Rescission and
Annulment. If an Event of Default described in paragraph (1), (2), (3) or (4) (if the Event of Default under paragraph (4) is with respect to less than all series of Securities then Outstanding) of Section 5.01 occurs and is
continuing with respect to any series, then and in each and every such case, unless the principal of all the Securities of such series shall have already become due and payable, either the Trustee or the Holders of not less than 25% in aggregate
principal amount of the Securities of such series then Outstanding hereunder (each such series acting as a separate class), by notice in writing to the Company (and to the Trustee if given by Holders), may declare the principal amount (or, if the
Securities of such series are Original Issue Discount Securities, such portion of the principal amount as may be specified in the terms of that series) of all the Securities of such series and all accrued interest thereon to be due and payable
immediately, and upon any such declaration the same shall become and shall be immediately due and payable, anything in this Indenture or in the Securities of such series contained to the contrary notwithstanding. If an Event of Default described in
paragraph (4) (if the Event of Default under paragraph (4) is with respect to all series of Securities then Outstanding), of Section 5.01 occurs and is continuing, then and in each and every such case, unless the principal of all the
Securities shall have already become due and payable, either the Trustee or the Holders of not less than 25% in aggregate principal amount of all the Securities then Outstanding hereunder (treated as one class), by notice in writing to the Company
(and to the Trustee if given by Holders), may declare the principal amount (or, if any Securities are Original Issue Discount Securities, such portion of the principal amount as may be specified in the terms thereof) of all the Securities then
Outstanding and all accrued interest thereon to be due and payable immediately, and upon any such declaration the same shall become and shall be immediately due and payable, anything in this Indenture or in the Securities contained to the contrary
notwithstanding. If an Event of Default of the type set forth in paragraph (5) or (6) of Section 5.01 occurs and is continuing, the principal of and any interest on the Securities then outstanding shall become immediately due and payable.

  
 29 

 At any time after such a declaration of acceleration has been made with respect to the Securities
of any or all series, as the case may be, and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the outstanding
Securities of such series, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if: 

(1) the Company has paid or deposited with the Trustee a sum sufficient to pay: 

(A) all overdue installments of interest on the Securities of such series; and 

(B) the principal of (and premium, if any, on) any Securities of such series which have become due otherwise than by such
declaration of acceleration, and interest thereon at the rate or rates prescribed therefor by the terms of the Securities of such series, to the extent that payment of such interest is lawful; and 

(C) interest upon overdue installments of interest at the rate or rates prescribed therefor by the terms of the Securities of
such series to the extent that payment of such interest is lawful; and 
 (D) all sums paid or advanced by the Trustee
hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and all other amounts due the Trustee under Section 6.07; and 

(2) all Events of Default with respect to such series of Securities, other than the nonpayment of the principal of the
Securities of such series that have become due solely by such acceleration, have been cured or waived as provided in Section 5.13. 
 No such
rescission shall affect any subsequent default or impair any right consequent thereon. 
 SECTION 5.03 Collection of Indebtedness and
Suits for Enforcement by Trustee. The Company covenants that if: 
 (1) default is made in the payment of any
installment of interest on any Security of any series when such interest becomes due and payable; or 
 (2) default is made
in the payment of the principal of (or premium, if any, on) any Security at the Maturity thereof; or 
 (3) default is made
in the payment of any sinking or purchase fund or analogous obligation when the same becomes due by the terms of the Securities of any series; 
 and any
such default continues for any period of grace provided with respect to the Securities of such series, the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holder of any such Security (or the Holders of any such series in
the case of Clause (3) above), the whole amount then due and payable on any such Security (or on the Securities of any such series in the case of Clause (3) above) for principal (and premium, if any) and interest, with interest, to the
extent that payment of such interest shall be legally enforceable, upon the overdue principal (and 

  
 30 

 
premium, if any) and upon overdue installments of interest, at such rate or rates as may be prescribed therefor by the terms of any such Security (or of Securities of any such series in the case
of Clause (3) above); and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel and all other amounts due the Trustee under Section 6.07. 
 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, and may prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company or any other obligor upon the Securities of such series and collect the money adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Securities, wherever
situated. 
 If an Event of Default with respect to any series of Securities 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 enforce 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 proceedings or otherwise: 
 (i) to file and prove a claim
for the whole amount of principal (or portion thereof determined pursuant to Section 3.01(16) to be provable in bankruptcy) (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 and 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 agents and counsel and all other amounts due the
Trustee under Section 6.07) and of the Securityholders allowed in such judicial proceeding; and 
 (ii) to collect and
receive any moneys or other property payable or deliverable on any such claims and to distribute the same; 
 and any receiver, assignee, trustee,
liquidator, sequestrator (or other similar official) in any such judicial proceeding is hereby authorized by each Securityholder to make such payment to the Trustee and in the event that the Trustee shall consent to the making of such payments
directly to the Securityholders, to pay to the Trustee any amount due to 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. 

  
 31 

 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or
accept or adopt on behalf of any Securityholder 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
Securityholder 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 of any series may be prosecuted and enforced by the Trustee without the possession of any of the Securities of such series 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 agent and counsel and any other amounts due the Trustee under Section 6.07, be for the ratable benefit of the Holders of the Securities of the series in respect of which such judgment has been recovered. 

SECTION 5.06 Application of Money Collected. Any money collected by the Trustee with respect to a series of Securities pursuant to
this Article 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 of such
series 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. 
 SECOND: To the payment of the amounts then due and unpaid upon the Securities
of that series for principal (and premium, if any) and interest, 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 for principal (and premium, if any) and interest, respectively. 
 THIRD: To the Company. 

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: 

(1) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to Securities
of such series; 
 (2) the Holders of not less than 25% in principal amount of the outstanding Securities of such 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; 

(3) such Holder or Holders have offered to the Trustee indemnity satisfactory to it against the costs, expenses and liabilities
to be incurred in compliance with such request; 
 (4) the Trustee for 60 days after its receipt of such notice, request and
offer of indemnity has failed to institute any such proceeding; and 

  
 32 

 (5) 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 such series; 
 it being understood and
intended that no one or more Holders of Securities of such 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 Holders of
Securities of such series, or to obtain or to seek to obtain priority or preference over any other such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and proportionate benefit of all the
Holders of all Securities of such series. 
 SECTION 5.08 Unconditional Right of Securityholders to Receive Principal, Premium and
Interest. Notwithstanding any other provisions 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 respective Stated Maturities expressed in such Security (or, in the case of redemption or repayment, on the Redemption Date or Repayment Date, as the case may be) and to institute suit for the
enforcement of any such payment, and such right shall not be impaired without the consent of such Holder. 
 SECTION 5.09 Restoration of
Rights and Remedies. If the Trustee or any Securityholder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, then and in every such case
the Company, the Trustee and the Securityholders shall, subject to any determination in such proceeding, be restored severally and respectively to their former positions hereunder, and thereafter all rights and remedies of the Trustee and the
Securityholders shall continue as though no such proceeding had been instituted. 
 SECTION 5.10 Rights and Remedies
Cumulative. No right or remedy herein conferred upon or reserved to the Trustee or to the Securityholders 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. 
 SECTION 5.11 Delay or Omission Not Waiver. No
delay or omission of the Trustee or of any Holder of any Security 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 Securityholders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Securityholders, as the case may be.

 SECTION 5.12 Control by Securityholders. 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: 
 (1) the Trustee shall have the right to decline to follow any such direction if the Trustee, being
advised by counsel, determines that the action so directed may not 

  
 33 

 
lawfully be taken or would conflict with this Indenture or if the Trustee in good faith shall, by a Responsible Officer, determine that the proceedings so directed would involve it in personal
liability or be unjustly prejudicial to the Holders not taking part in such direction, and 
 (2) the Trustee may take any
other action deemed proper by the Trustee that is not inconsistent with such direction. 
 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 on behalf of the Holders of all the Securities of such series waive any past default hereunder with respect to such series
and its consequences, except a default not theretofore cured: 
 (1) 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 or purchase fund or analogous obligation with respect to the Securities of such series, or 

(2) in respect of a covenant or provision hereof which under Article IX cannot be modified or amended without the consent of
the Holder of each Outstanding Security of such series. 
 Upon any such waiver, such default shall cease to exist, and any Event of Default
arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other 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 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 such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, 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 Trustee, to any suit instituted by any Securityholder, or
group of Securityholders, holding in the aggregate more than 10% in principal amount of the Outstanding Securities of any series to which the suit relates, or to any suit instituted by any Securityholder for the enforcement of the payment of the
principal of (or premium, if any) or interest on a Security on or after the respective Stated Maturities expressed in such Security (or, in the case of redemption or repayment, on or after the Redemption Date or Repayment Date, as the case may be).

 SECTION 5.15 Waiver of Stay or Extension 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 or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of
this Indenture; and the Company (to the extent that it may lawfully do so) 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.

 ARTICLE VI 

The Trustee 

SECTION 6.01 Certain Duties and Responsibilities. (a) Except during the continuance of an Event of Default with respect to any
series of Securities: 
 (1) the Trustee undertakes to perform such duties and only such duties as are specifically set forth
in this Indenture with respect to the Securities of such series, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 

(2) in the absence of bad faith on its part, the Trustee may, with respect to Securities of such series, conclusively rely, as
to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such certificates or opinions
that by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture (but need not confirm or
investigate the accuracy of mathematical calculations or other facts stated therein). 
 (b) In case an Event of Default with respect to any
series of Securities has occurred and is continuing, the Trustee shall exercise with respect to the Securities of such series such of the rights and powers vested in it by this Indenture and any indenture supplemental hereto or Board Resolution
relating to such series of Securities, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. 

(c) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent
failure to act, or its own willful misconduct, except that: 
 (1) this Subsection shall not be construed to limit the effect
of Subsection (a) of this Section; 
 (2) the Trustee shall not be liable for any error of judgment made in good faith by a
Responsible Officer, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; 
 (3) in
no event shall the Trustee be responsible or liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the
likelihood of such loss or damage and regardless of the form of action; 
 (4) the Trustee shall not be liable with respect
to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of a majority in principal amount of the Outstanding Securities of any series relating to the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture with respect to the Securities of such series; and 

  
 35 

 (5) no provision of this Indenture shall require the Trustee 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 any 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. 
 (d) Whether or not therein expressly so provided, every
provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section. 

SECTION 6.02 Notice of Defaults. Within 90 days after the occurrence of any default hereunder with respect to Securities of any
series, the Trustee shall transmit by mail to all Securityholders of such series, as their names and addresses appear in the Security Register, notice of such default hereunder known to the Trustee, unless such default shall have been cured or
waived; provided, however, that, except in the case of a 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 or purchase fund installment or
analogous obligation with respect to Securities of such series, the Trustee shall be protected in withholding such notice if and so long as it in good faith determines that the withholding of such notice is in the interests of the Securityholders of
such series; and provided, further, that in the case of any default of the character specified in Section 5.01(4) with respect to Securities of such series no such notice to Securityholders of such series shall be given until at least
90 days after the occurrence thereof. For the purpose of this Section, the term “default”, with respect to Securities of any series, means any event that is, or after notice or lapse of time or both would become, an Event of Default with
respect to Securities of such series. 
 SECTION 6.03 Certain Rights of Trustee. Except as otherwise provided in Section 6.01:

 (a) the Trustee may conclusively rely and shall be fully protected in acting or refraining from acting upon any
resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties
and the Trustee need not investigate any fact or matter stated in such document; 
 (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 Officers’ Certificate; 

(d) the Trustee may consult with counsel of its own selection and the advice of such counsel or an 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; 

  
 36 

 (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 Securityholders pursuant to this Indenture, unless such Securityholders shall have offered to the Trustee security or indemnity satisfactory to it against the costs,
expenses and liabilities that might be incurred by it in compliance with such request or direction; 
 (f) 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, bond, debenture or other paper or document, but the Trustee,
in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and
premises of the Company, personally or by agent or attorney; 
 (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 charged with knowledge of any default (as defined in Section 6.02) or Event of Default with
respect to the Securities of any series for which it is acting as Trustee unless either (1) a Responsible Officer of the Trustee assigned to the Corporate Trust Department of the Trustee (or any successor division or department of the Trustee) shall
have actual knowledge of such default or Event of Default or (2) written notice of such default or Event of Default shall have been given to the Trustee by the Company or any other obligor on such Securities or by any Holder of such Securities and
such notice references this Indenture; 
 (i) the Trustee shall not be liable for any action taken, suffered or omitted by it
in good faith and believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture; 

(j) the rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right
to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder; 

(k) before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel or
both. The Trustee will not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel; 

(l) the Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties
hereunder; and 
 (m) unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from
the Issuer will be sufficient if signed by an Officer of the Issuer. 
 SECTION 6.04 Not Responsible for Recitals or Issuance of
Securities. The recitals contained herein and in the Securities, except the certificates 

  
 37 

 
of authentication, shall be taken as the statements of the Company, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity
or sufficiency of this Indenture or of the Securities. The Trustee shall not be accountable for the use or application by the Company of Securities or the proceeds thereof. 

SECTION 6.05 May Hold Securities. The Trustee, any Authenticating Agent, any Paying Agent, the Security Registrar, any Conversion
Agent 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 otherwise deal with the Company with the same rights it would have if it were
not Trustee, Authenticating Agent, Paying Agent, Security Registrar, Conversion Agent or such other agent. 
 SECTION 6.06 Money Held in
Trust. Subject to the provisions of Section 10.03 hereof, all moneys in any currency or currency received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but
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 in writing with the Company. 

SECTION 6.07 Compensation and Reimbursement. The Company agrees: 

(1) to pay to the Trustee from time to time such compensation as is agreed in writing 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); 

(2) 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 shall be determined to have been caused by its own negligence, bad faith or willful misconduct; and 
 (3) to
indemnify the Trustee for, and to hold it and its officers, directors, stockholders, and employees, harmless against, any loss, liability or expense incurred without negligence, bad faith or willful misconduct on its part, arising out of or in
connection with the acceptance or administration of this trust, including the costs and expenses of defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. 

The Trustee shall promptly notify the Company in writing of any claim for which it may seek indemnity hereunder, provided that failure
by the Trustee to so notify the Company shall not relieve the Company of its indemnity obligations hereunder, except to the extent that the Company is actually prejudiced by such failure. The Company will defend any such claims and the Trustee
will cooperate in its defense. To the extent that a conflict of interest exists between the Company and the Trustee, the Trustee may have separate counsel, and the Company will pay the reasonable fees and expenses of such counsel. The
Company shall not be obligated to pay for any settlement made without its consent. 

  
 38 

 When the Trustee incurs expenses or renders services in connection with an Event of Default
specified in Section 5.01(5) or (6), the expenses and the compensation for the services are intended to constitute expenses of administration under any bankruptcy law. 

As security for the performance of the obligations of the Company under this Section, the Trustee shall have a lien prior to the Securities
upon all property and funds held or collected by the Trustee as such, except funds held in trust for the payment of principal of (and premium, if any) or interest on particular Securities. 

The Company’s obligations under this Section 6.07 and any lien arising hereunder shall survive the resignation or removal of any Trustee,
the discharge of the Company’s obligations pursuant to Article IV of this Indenture and/or the termination of this Indenture (including any termination or rejection hereof under any bankruptcy law). 

SECTION 6.08 Disqualification; Conflicting Interests. The Trustee for the Securities of any series issued hereunder shall be
subject to the provisions of Section 310(b) of the Trust Indenture Act during the period of time provided for therein. In determining whether the Trustee has a conflicting interest as defined in Section 310(b) of the Trust Indenture Act with
respect to the Securities of any series, there shall be excluded this Indenture with respect to Securities of any particular series of Securities other than that series. Nothing herein 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. 
 SECTION 6.09 Corporate
Trustee Required; Eligibility. There shall at all times be a Trustee hereunder with respect to each series of Securities, which shall be either: 

(i) a corporation organized and doing business under the laws of the United States of America or of any State, authorized under
such laws to exercise corporate trust powers and subject to supervision or examination by Federal or State authority, or 

(ii) a corporation or other Person organized and doing business under the laws of a foreign government that is permitted to act
as Trustee pursuant to a rule, regulation or order of the Commission, authorized under such laws to exercise corporate trust powers, and subject to supervision or examination by authority of such foreign government or a political subdivision thereof
substantially equivalent to supervision or examination applicable to United States institutional trustees; 
 in either case having a combined capital and
surplus of at least $50,000,000. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid 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 shall serve as trustee for the Securities of any series issued hereunder. If at any time the Trustee with respect to any series of Securities shall cease to be eligible in accordance with
the provisions of this Section, it shall resign immediately in the manner and with the effect specified in Section 6.10. 

  
 39 

 SECTION 6.10 Resignation and Removal. (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 under Section 6.11. 

(b) The Trustee may resign with respect to any series of Securities at any time by giving written notice thereof to the Company and be
discharged from the trust created hereby. If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee (at the Company’s
expense) may petition any court of competent jurisdiction for the appointment of a successor Trustee. 
 (c) The Trustee may be removed with
respect to any series of Securities at any time by Act of the Holders of a majority in principal amount of the outstanding Securities of that series, delivered to the Trustee and to the Company in writing not less than 30 days prior to the effective
date of such removal. If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 30 days after the giving of such notice of removal, the removed Trustee (at the Company’s expense) may petition any
court of competent jurisdiction for the appointment of a successor Trustee. 
 (d) If at any time: 

(1) the Trustee shall fail to comply with Section 310(b) of the Trust Indenture Act pursuant to Section 6.08 with respect to
any series of Securities after written request therefor by the Company or by any Securityholder who has been a bona fide Holder of a Security of that series for at least six months, unless the Trustee’s duty to resign is stayed in accordance
with the provisions of Section 310(b) of the Trust Indenture Act, or 
 (2) the Trustee shall cease to be eligible under
Section 6.09 with respect to any series of Securities and shall fail to resign after written request therefor by the Company or by any such Securityholder, or 

(3) the Trustee shall become incapable of acting with respect to any series of Securities, or 

(4) the Trustee 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, (i) the Company by a Board Resolution may remove the Trustee, with
respect to the series, or in the case of Clause (4), with respect to all series, or (ii) subject to Section 5.14, any Securityholder 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 removal of the Trustee and the appointment of a successor Trustee with respect to the series, or, in the case of Clause (4), with respect to all series. 

(e) If the Trustee shall resign, be removed or become incapable of acting with respect to any series of Securities, or if a vacancy shall
occur in the office of the Trustee with respect to any series of Securities for any cause, the Company, by Board Resolution, shall promptly appoint a successor Trustee for that series of Securities. 

  
 40 

 If, within one year after such resignation, removal or incapacity, or the occurrence of such vacancy, a successor
Trustee with respect to such series of Securities 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, become the successor Trustee with respect to such series and supersede the successor Trustee appointed by the Company with respect to such series. If no successor Trustee with
respect to such series shall have been so appointed by the Company or the Securityholders of such series and accepted appointment in the manner hereinafter provided, subject to Section 5.14, any Securityholder who has been a bona fide Holder of a
Security of that 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 such series. 

(f) The Company shall give notice of each resignation and each removal of the Trustee with respect to any series and each appointment of a
successor Trustee with respect to any series by mailing written notice of such event by first-class mail, postage prepaid, to the Holders of Securities of that series as their names and addresses appear in the Security Register. Each notice
shall include the name of the successor Trustee and the address of its principal Corporate Trust Office. 
 SECTION 6.11 Acceptance of
Appointment by Successor. Every successor Trustee appointed hereunder shall execute, acknowledge and deliver to the Company and to the predecessor Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the
predecessor Trustee shall become effective with respect to any series as to which it is resigning or being removed as Trustee, and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers,
trusts and duties of the predecessor Trustee with respect to any such series; but, on request of the Company or the successor Trustee, such predecessor Trustee shall, upon payment of its fees and expenses provided for herein, if any, execute and
deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the predecessor Trustee, and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such predecessor trustee
hereunder with respect to all or any such series, subject nevertheless to its lien, if any, provided for in Section 6.07. 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. Notwithstanding the replacement of the Trustee, the Company’s obligations under Section 6.07 hereof will continue for the benefit of the retiring Trustee.

 In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the
Company, the predecessor Trustee and each successor Trustee with respect to the Securities of any applicable series shall execute and deliver an indenture supplemental hereto which shall contain such provisions as shall be deemed necessary or
desirable to confirm that all the rights, powers, trusts and duties of the predecessor Trustee with respect to the Securities of any series as to which the predecessor Trustee is not being succeeded shall continue to be vested in the predecessor
Trustee, and 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
indenture supplemental hereto 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. 

  
 41 

 No successor Trustee with respect to any series of Securities shall accept its appointment unless
at the time of such acceptance such successor Trustee shall be qualified and eligible with respect to that series under this Article. 
 The
Trustee shall have no responsibility or liability whatsoever for the action or inaction of any successor Trustee. 
 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 of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder without further action on the part of the Trustee,
provided that 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 TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated.

 SECTION 6.14 Appointment of Authenticating Agent. At any time when any of the Securities remain Outstanding the Trustee, with the
approval of the Company, may appoint an Authenticating Agent or Agents with respect to one or more series of Securities that shall be authorized to act on behalf of the Trustee to authenticate Securities of such series issued upon original issuance,
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 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 an Authenticating Agent, having a combined capital and surplus of not less
than $50,000,000 and, if other than the Company itself, 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, 

  
 42 

 
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, if other than the Company, 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, if other than the Company, 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, with the approval of the Company, may appoint a successor Authenticating Agent
that 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. 

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 addition to the Trustee’s certificate of authentication, an alternate certificate of authentication in the following form: 

This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

 ARTICLE VII 

Securityholders’ Lists and Reports by 

Trustee and Company 

SECTION 7.01 Company to Furnish Trustee Names and Addresses of Securityholders.  

The Company will furnish or cause to be furnished to the Trustee: 

(1) semi-annually, not more than 15 days after December 15 and June 15 in each year in such form as the Trustee may
reasonably require, a list of the names and addresses of the Holders of Securities of each series as of such December 15 and June 15, as applicable, and 

(2) 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; provided, however, that if and so long as the Trustee shall be the Security Registrar for Securities of a series,
no such list need be furnished with respect to such series of Securities. 
 SECTION 7.02 Preservation of Information; Communications to
Securityholders. (a) The Trustee shall preserve, in as current a form as is reasonably practicable, the names and addresses of Holders of Securities contained in the most recent list furnished to the Trustee as provided in Section 7.01 and
the names and addresses of Holders of Securities received by the Trustee in its capacity as Security Registrar, if so acting. The Trustee may destroy any list furnished to it as provided in Section 7.01 upon receipt of a new list so furnished.

 (b) If three or more Holders of Securities of any series (hereinafter 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 of such series 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 of Securities of such series or with the Holders of all Securities with respect to their rights under this Indenture or under such Securities and is accompanied by a copy of the form of proxy or other communication
that such applicants propose to transmit, then the Trustee shall, within five Business Days after the receipt of such application, at its election, either: 

(1) afford such applicants access to the information preserved at the time by the Trustee in accordance with Section 7.02(a),
or 
 (2) inform such applicants as to the approximate number of Holders of Securities of such series or all Securities, as
the case may be, 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 Securityholders 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 of a Security of such series or to all Securityholders, as the case may be, whose names and addresses appear in the 

  
 44 

 
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 that 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 interests of the Holders of Securities of such series or all
Securityholders, as the case may be, 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 the
objections so sustained have been met and shall enter an order so declaring, the Trustee shall mail copies of such material to all Securityholders of such series or all Securityholders, as the case may be, 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 shall be held accountable by reason of the disclosure of any such information as to the names and addresses of the Holders of Securities in accordance with Section 7.02(b), regardless of the source from which such 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. (a) Within 60 days after May 15 of each year commencing with the first May 15 after the
issuance of Securities, the Trustee shall transmit by mail, at the Company’s expense, to all Holders as their names and addresses appear in the Security Register, as provided in Trust Indenture Act Section 313(c), a brief report dated as of
May 15 in accordance with and with respect to the matters required by Trust Indenture Act Section 313(a) (but if no event described in Trust Indenture Act Section 313(a) has occurred within the twelve months preceding the reporting date, no
report need be transmitted). 
 (b) The Trustee shall transmit by mail, at the Company’s expense, to all Holders as their names and
addresses appear in the Security Register, as provided in Trust Indenture Act Section 313(c), a brief report in accordance with and with respect to the matters required by Trust Indenture Act Section 313(b), if required by Section 313(b). 

(c) A copy of each such report shall, at the time of such transmission to Holders, be furnished to the Company and, in accordance with Trust
Indenture Act Section 313(d), be filed by the Trustee with each stock exchange upon which the Securities are listed, and also with the Commission. 

SECTION 7.04 Reports by Company. The Company shall file with the Trustee, and transmit to Holders, such information, documents and
other reports, and such summaries thereof, as may be required pursuant to the Trust Indenture Act at the times and in the manner provided pursuant to such Act; provided that any such information, documents or reports required to be filed with
the Commission pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 shall be filed with the Trustee within 15 days after the same is so required to be filed with the Commission. The Company also shall comply with the other

Supplemental Indentures 

SECTION 9.01 Supplemental Indentures Without Consent of Securityholders. Without the consent of the Holders of any Securities, the
Company, when authorized by a Board Resolution, and the Trustee, at any time and from time to time, may enter into one or more indentures supplemental hereto, in form reasonably satisfactory to the Trustee, for any of the following purposes: 

(1) to evidence the succession of another corporation or Person to the Company, and the assumption by any such successor of the
respective covenants of the Company herein and in the Securities contained; or 
 (2) to add to the covenants of the Company,
or to surrender any right or power herein conferred upon the Company, for the benefit of the Holders of the Securities of any or all series (and if such covenants or the surrender of such right or power are to be for the benefit of less than all
series of Securities, stating that such covenants are expressly being included or such surrenders are expressly being made solely for the benefit of one or more specified series); or 

(3) to cure any ambiguity, to correct or supplement any provision herein that may be inconsistent with any other provision
herein, or to make any other provisions with respect to matters or questions arising under this Indenture; or 
 (4) to add
to this Indenture such provisions as may be expressly permitted by the TIA, excluding, however, the provisions referred to in TIA Section 316(a)(2) as in effect at the date as of which this instrument was executed or any corresponding provision in
any similar federal statute hereafter enacted; or 
 (5) to establish any form of Security, as provided in Article II, to
provide for the issuance of any series of Securities as provided in Article III and to set forth the terms thereof, and/or to add to the rights of the Holders of the Securities of any series; or 

(6) to evidence and provide for the acceptance of appointment by another corporation as a successor Trustee hereunder with
respect to one or more series of Securities and to 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, pursuant to Section
6.11; or 
 (7) to add any additional Events of Default in respect of the Securities of any or all series (and if such
additional Events of Default are to be in respect of less than all series of Securities, stating that such Events of Default are expressly being included solely for the benefit of one or more specified series); or 

(8) to provide for uncertificated Securities in addition to or in place of certificated Securities and to provide for bearer
Securities; provided that uncertificated Securities are issued in registered form for purposes of Section 163(f) of the Internal Revenue Code of 1986, as amended, or in a manner such that the uncertificated Securities are described in Section
163(f)(2)(B) of such Internal Revenue Code; or 

  
 47 

 (9) to provide for the terms and conditions of conversion into Common Stock or
other Marketable Securities of the Securities of any series that are convertible into Common Stock or other Marketable Securities, if different from those set forth in Article XII; or 

(10) to secure the Securities of any series; or 

(11) to add guarantors in respect of the Securities; or 

(12) to make any other change that does not adversely affect the rights of the Holders of any or all series of Securities in
any material respect; or 
 (13) to make any change necessary to comply with any requirement of the Commission in connection
with the qualification of this Indenture or any supplemental indenture under the Trust Indenture Act or to comply with the rules of any applicable securities depositary. 

No supplemental indenture for the purposes identified in Clauses (2), (3), (5) or (7) above may be entered into if to do so would adversely
affect the rights of the Holders of Outstanding Securities of any series in any material respect. 
 SECTION 9.02 Supplemental Indentures
with Consent of Securityholders. With the consent of the Holders of not less than a majority in principal amount of the Outstanding Securities of all series affected by such supplemental indenture or indentures (acting as one class), by Act
of said Holders delivered to the Company and the Trustee (in accordance with Section 1.04 hereof), the Company, when authorized by a Board Resolution, and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of
adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of modifying in any manner the rights of the Holders of the Securities of each such series under this Indenture; provided,
however, that no such supplemental indenture shall, without the consent of the Holder of each Outstanding Security affected thereby: 

(1) change the Maturity of the principal of, or the Stated Maturity of any premium on, or any installment of interest on, any
Security, or reduce the principal amount thereof or the interest or any premium thereon, or change the method of computing the amount of principal thereof or interest thereon on any date or change any Place of Payment where, or the coin or currency
in which, any Security or any premium or interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or after the Maturity or the Stated Maturity, as the case may be, thereof (or, in the case of
redemption or repayment, on or after the Redemption Date or the Repayment Date, as the case may be), or alter the provisions of this Indenture so as to affect adversely the terms, if any, of conversion of any Securities into Common Stock or other
securities; or 
 (2) reduce the percentage in principal amount of the Outstanding Securities of any series, the consent of
whose Holders is required for any such supplemental indenture, or the consent of whose Holders is required for any waiver of compliance with certain provisions of this Indenture or certain defaults hereunder and their consequences, provided for in
this Indenture; or 

  
 48 

 (3) modify any of the provisions of this Section 9.02 or Section 5.13, except to
increase any such percentage or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; or 

(4) impair or adversely affect the right of any Holder to institute suit for the enforcement of any payment on, or with respect
to, the Securities of any series on or after the Stated Maturity of such Securities (or in the case of redemption, on or after the Redemption Date). 

For purposes of this Section 9.02, if the Securities of any series are issuable upon the exercise of warrants, each holder of an unexercised
and unexpired warrant with respect to such series shall be deemed to be a Holder of Outstanding Securities of such series in the amount issuable upon the exercise of such warrant. For such purposes, the ownership of any such warrant shall be
determined by the Company in a manner consistent with customary commercial practices. The Trustee for such series shall be entitled to rely on an Officers’ Certificate as to the principal amount of Securities of such series in respect of which
consents shall have been executed by holders of such warrants. 
 A supplemental indenture that changes or eliminates any covenant or other
provision of this Indenture that has expressly been included solely for the benefit of one or more particular series of Securities, or that modifies the rights of the Holders of Securities of such series with respect to such covenant or other
provision, shall be deemed not to affect the rights under this Indenture of Holders of Securities of any other series. 
 It shall not be
necessary for any Act of Securityholders under this Section to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof. 

SECTION 9.03 Execution of Supplemental Indentures. In executing, or accepting the additional trusts created by, any supplemental
indenture permitted by this Article or the modifications thereby of the trusts created by this Indenture, the Trustee shall receive, and (subject to Section 6.01) shall be fully protected in conclusively relying upon, an Officers’ Certificate
and an Opinion of Counsel stating that the execution of such supplemental indenture is authorized or permitted by this Indenture and that all conditions precedent relating to the execution of such supplemental indenture provided for hereunder have
been satisfied. The Trustee may, but shall not be obligated to, enter into any such supplemental indenture that affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise. 

SECTION 9.04 Effect of Supplemental Indentures. Upon the execution of any supplemental indenture under this Article, this
Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Securities theretofore or thereafter authenticated and delivered hereunder shall be bound
thereby to the extent provided therein. 
 SECTION 9.05 Conformity with Trust Indenture Act. Every supplemental indenture
executed pursuant to this Article shall conform to the requirements of the TIA as then in effect. 
 SECTION 9.06 Reference in Securities
to Supplemental Indentures. Securities authenticated and delivered after the execution of any supplemental indenture pursuant 

  
 49 

 
to this Article may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company shall
so determine, new Securities so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any such supplemental indenture may be prepared and executed by the Company and authenticated and delivered by the Trustee in
exchange for Outstanding Securities. 
 ARTICLE X 

Covenants 

SECTION 10.01 Payment of Principal, Premium and Interest. With respect to each series of Securities and prior to 10:00am New York
City time on each Interest Payment Date, the Company will duly and punctually pay the principal of (and premium, if any) and interest on such Securities in accordance with their terms and this Indenture, and will duly comply with all the other
terms, agreements and conditions contained in, or made in the Indenture for the benefit of, the Securities of such series. 
 SECTION 10.02
Maintenance of Office or Agency. The Company will maintain an office or agency in each Place of Payment where Securities may be presented or surrendered for payment, where Securities may be surrendered for registration of transfer or
exchange, where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served and where any Securities with conversion privileges may be presented and surrendered for conversion. The Company will give
prompt written notice to the Trustee of the location, and of any change in the location, of such office or agency. If at any time the Company shall fail to maintain such office or agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee its agent to receive all such presentations, surrenders, notices and
demands. 
 Unless otherwise set forth in, or pursuant to, a Board Resolution or indenture supplemental hereto with respect to a series of
Securities, the Company hereby initially designates as the Place of Payment for each series of Securities, the Borough of Manhattan, the City and State of New York, and initially appoints the Trustee at its Corporate Trust Office as the
Company’s office or agency for each such purpose in such city. 
 SECTION 10.03 Money for Security Payments to Be Held in
Trust. If the Company shall at any time act as its own Paying Agent for 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 such 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 in writing of its action or failure to act. 
 Whenever the Company shall have one or more Paying Agents
for any series of Securities, it will, on or prior to each due date of the principal of (and premium, if any) or interest on, any Securities of such 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 (and premium, if any) or interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee in writing
of its action or failure so to act. 

  
 50 

 The Company will cause each Paying Agent other than the Trustee for any series of Securities 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: 

(1) hold all sums held by it for the payment of principal of (and premium, if any) or interest on Securities of such 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; 

(2) give the Trustee notice of any default by the Company (or any other obligor upon the Securities of such series) in the
making of any such payment of principal (and premium, if any) or interest on the Securities of such series; and 
 (3) 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 with respect to any series of
Securities 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 in respect of each and every series of Securities as to which it seeks to
discharge this Indenture or, if for any other purpose, all sums so held in trust by the Company in respect of all Securities, 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, 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. The Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company mail to the Holders of the Securities
as to which the money to be repaid was held in trust, as their names and addresses appear in the Security Register, a notice that such moneys remain unclaimed and that, after a date specified in the notice, which shall not be less than 30 days from
the date on which the notice was first mailed to the Holders of the Securities as to which the money to be repaid was held in trust, any unclaimed balance of such moneys then remaining will be paid to the Company free of the trust formerly impressed
upon it. 
 SECTION 10.04 Statement as to Compliance. The Company will deliver to the Trustee, within 120 days after the end of
each fiscal year, a written statement signed by the principal executive officer, principal financial officer or principal accounting officer of the Company stating that: 

(1) a review of the activities of the Company during such year and of performance under this Indenture and under the terms of
the Securities has been made under his supervision with a view to determining whether the Company has kept, observed, performed and fulfilled its obligations under this Indenture; and 

  
 51 

 (2) to his or her knowledge, based on such review, the Company has fulfilled all
its obligations under this Indenture and has complied with all conditions and covenants on its part contained in this Indenture through such year, or, if there has been a default in the fulfillment of any such obligation, covenant or condition,
specifying each such default known to him and the nature and status thereof. 
 For the purpose of this Section 10.04, default and
compliance shall be determined without regard to any grace period or requirement of notice provided pursuant to the terms of this Indenture. The Company shall, as long as any of the Securities are outstanding, deliver to the Trustee forthwith and,
in any event, within 30 days, upon becoming aware of any Event of Default, an Officers’ Certificate specifying such Event of Default and what action the Company is taking or proposes to take with respect thereto (unless such default has been
previously cured or waived). 
 SECTION 10.05 Legal Existence. Subject to Article VIII, the Company will do or cause to be done
all things necessary to preserve and keep in full force and effect its legal existence. 
 SECTION 10.06 Waiver of Certain
Covenants. The Company may omit in respect of any series of Securities, in any particular instance, to comply with any covenant or condition set forth in Section 10.05 or set forth in a Board Resolution or indenture supplemental hereto with
respect to the Securities of such series, unless otherwise specified in such Board Resolution or indenture supplemental hereto, if before or after the time for such compliance the Holders of not less than a majority in principal amount of the
Outstanding Securities of all series affected by such waiver (voting as one class) shall, by Act of such Securityholders delivered to the Company and the Trustee (in accordance with Section 1.04 hereof), either waive such compliance in such instance
or generally waive compliance with such covenant or condition, but no such waiver shall extend to or affect such covenant or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the
Company and the duties of the Trustee in respect of any such covenant or condition shall remain in full force and effect. Nothing in this Section 10.06 shall permit the waiver of compliance with any covenant or condition set forth in such Board
Resolution or indenture supplemental hereto which, if in the form of an indenture supplemental hereto, would not be permitted by Section 9.02 without the consent of the Holder of each Outstanding Security affected thereby. 

ARTICLE XI 

Redemption of Securities 

SECTION 11.01 Applicability of Article. The Company may reserve the right to redeem and pay before Stated Maturity all or any part
of the Securities of any series, either by optional redemption, sinking or purchase fund or analogous obligation or otherwise, by provision therefor in the form of Security for such series established and approved pursuant to Section 2.02 and on
such terms as are specified in such form or in the Board Resolution or indenture supplemental hereto with respect to Securities of such series as provided in Section 3.01. Redemption of Securities of any series shall be made in accordance with the
terms of such 

  
 52 

 
Securities and, to the extent that this Article does not conflict with such terms, the succeeding Sections of this Article. Notwithstanding anything to the contrary in this Indenture, except
in the case of redemption pursuant to a sinking fund, the Trustee shall not make any payment in connection with the redemption of Securities until the close of business on the Redemption Date. 

SECTION 11.02 Election to Redeem; Notice to Trustee. The election of the Company to redeem any Securities redeemable at the
election of the Company shall be evidenced by, or pursuant to authority granted by, a Board Resolution. In case of any redemption at the election of the Company of less than all of 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 reasonably satisfactory to the Trustee), notify the Trustee in writing of such Redemption Date and of the principal amount of Securities of such series and the
Tranche (as defined in Section 11.03) to be redeemed. 
 In the case of any redemption of Securities (i) prior to the expiration of any
restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, or (ii) pursuant to an election of the Company that is subject to a condition specified in the terms of such Securities, the Company shall
furnish the Trustee with an Officers’ Certificate evidencing compliance with such restriction or condition. 
 SECTION 11.03
Selection by Trustee of Securities to Be Redeemed. If less than all the Securities of like tenor and terms of any series (a “Tranche”) are to be redeemed, the particular Securities to be redeemed shall be selected not more
than 45 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such Tranche not previously called for redemption, by such method as the Trustee shall deem fair and appropriate (and in all cases in accordance with the
procedures of the depositary) and that may include provision for the selection for redemption of portions of the principal of Securities of such Tranche of a denomination larger than the minimum authorized denomination for Securities of that series.
Unless otherwise provided in the terms of a particular series of Securities, the portions of the principal of Securities so selected for partial redemption shall be equal to the minimum authorized denomination of the Securities of such series, or an
integral multiple thereof, and the principal amount that remains outstanding shall not be less than the minimum authorized denomination for Securities of such series. If less than all the Securities of unlike tenor and terms of a series are to
be redeemed, the particular Tranche of Securities to be redeemed shall be selected by the Company. 
 If any convertible Security selected
for partial redemption is converted in part before the termination of the conversion right with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed (so far as may be) to be the portion selected
for redemption. 
 Upon any redemption of fewer than all the Securities of a series, the Company and the Trustee may treat as Outstanding
any Securities surrendered for conversion during the period of fifteen days next preceding the mailing of a notice of redemption, and need not treat as Outstanding any Security authenticated and delivered during such period in exchange for the
unconverted portion of any Security converted in part during such period. 
 The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption and, in the case of any Security selected for partial redemption, the principal amount thereof to be redeemed. 

  
 53 

 Securities shall be excluded from eligibility for selection for redemption if they are identified
by registration and certificate number in a written statement signed by an authorized officer of the Company and delivered to the Trustee at least 45 days prior to the Redemption Date (unless a shorter period shall be reasonably satisfactory to the
Trustee) as being owned of record and beneficially by, and not pledged or hypothecated by either, (a) the Company or (b) an entity specifically identified in such written statement as being an Affiliate of the Company. 

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall
relate, in the case of any Security redeemed or to be redeemed only in part, to the portion of the principal of such Security that 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
15 (unless otherwise provided in the Board Resolution or indenture supplemental hereto establishing the relevant series) nor more than 45 days prior to the Redemption Date, to each holder of Securities to be redeemed, at his address appearing in the
Security Register. 
 All notices of redemption shall state: 

(1) the Redemption Date; 

(2) the Redemption Price; 

(3) if less than all Outstanding Securities of any series are to be redeemed, the identification (and, in the case of partial
redemption, the respective principal amounts) of the Securities to be redeemed; 
 (4) that on the Redemption Date the
Redemption Price will become due and payable upon each such Security, and that interest, if any, thereon shall cease to accrue from and after said date; 

(5) the place where such Securities are to be surrendered for payment of the Redemption Price, which shall be the office or
agency of the Company in the Place of Payment; 
 (6) that the redemption is on account of a sinking or purchase fund, or
other analogous obligation, if that be the case; 
 (7) if such Securities are convertible into Common Stock or other
securities, the Conversion Price or other conversion price and the date on which the right to convert such Securities into Common Stock or other securities will terminate; 

(8) CUSIPs and/or ISIN numbers (if applicable); and 

(9) if applicable, that the redemption may be rescinded by the Company, at its sole option, pursuant to Section 11.09 of this
Indenture upon the occurrence of a Redemption Rescission Event. 
 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; provided that if the Trustee is asked to give such notice it shall be given at least five (5) Business Days
prior notice. 

  
 54 

 Any redemption or notice of any redemption may, at the Company’s discretion, be subject to
one or more conditions precedent, including, but not limited to, completion of a securities offering, other offering, issuance of indebtedness, or other transaction or event. Notice of any redemption in respect thereof will be given prior to the
completion thereof and may be partial as a result of only some of the conditions being satisfied. The Company may provide in such notice that payment of the redemption price and the performance of the Company’s obligations with respect to such
redemption may be performed by another Person. 
 SECTION 11.05 Deposit of Redemption Price. At or prior to 10:00am New York
City time on any Redemption Date and subject to Section 11.09, 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 10.03) an
amount of money, in immediately available funds, sufficient to pay the Redemption Price of all the Securities that are to be redeemed on that date. If any Security to be redeemed is converted into Common Stock or other securities, any money so
deposited with the Trustee or a Paying Agent shall be paid to the Company upon Company Request or, if then so segregated and held in trust by the Company, shall be discharged from such trust. 

SECTION 11.06 Securities Payable on Redemption Date. Notice of redemption having been given as aforesaid, the Securities so to be
redeemed shall, subject to Section 11.09, 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) such Securities
shall cease to bear interest and any rights to convert such Securities shall terminate. Upon surrender of such Securities for redemption in accordance with the notice and subject to Section 11.09, such Securities shall be paid by the Company at
the Redemption Price. Unless otherwise provided with respect to such Securities pursuant to Section 3.01, installments of interest the Stated Maturity of which is on or prior to the Redemption Date shall be payable to the Holders of such
Securities registered as such on the relevant Regular 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 shall, until paid, bear interest from the Redemption Date at the rate borne by the Security, or as otherwise provided in such Security. 

SECTION 11.07 Securities Redeemed in Part. Any Security that is to be redeemed only in part shall be surrendered at the office or
agency of the Company in the Place of Payment with respect to that series (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 and of like tenor and terms, 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. 

SECTION 11.08 Provisions with Respect to Any Sinking Funds. Unless the form or terms of any series of Securities shall provide
otherwise, in lieu of making all or any part of any mandatory sinking fund payment with respect to such series of Securities in 

  
 55 

 
cash, the Company may at its option (1) deliver to the Trustee for cancellation any Securities of such series theretofore acquired by the Company or converted by the Holder thereof into Common
Stock or other securities, or (2) receive credit for any Securities of such series (not previously so credited) acquired by the Company (including by way of optional redemption (pursuant to the sinking fund or otherwise but not by way of mandatory
sinking fund redemption) or converted by the Holder thereof into Common Stock or other securities and theretofore delivered to the Trustee for cancellation, and if it does so then (i) Securities so delivered or credited shall be credited at the
applicable sinking fund Redemption Price with respect to Securities of such series, and (ii) on or before the 60th day next preceding each sinking fund Redemption Date with respect to such series of Securities, the Company will deliver to the
Trustee (A) an Officers’ Certificate specifying the portions of such sinking fund payment to be satisfied by payment of cash and by delivery or credit of Securities of such series acquired by the Company or converted by the Holder thereof, and
(B) such Securities, to the extent not previously surrendered. Such Officers’ Certificate shall also state the basis for such credit and that the Securities for which the Company elects to receive credit have not been previously so credited and
were not acquired by the Company through operation of the mandatory sinking fund, if any, provided with respect to such Securities and shall also state that no Event of Default with respect to Securities of such series has occurred and is
continuing. All Securities so delivered to the Trustee shall be canceled by the Trustee and no Securities shall be authenticated in lieu thereof. 

If the sinking fund payment or payments (mandatory or optional) with respect to any series of Securities made in cash plus any unused balance
of any preceding sinking fund payments with respect to Securities of such series made in cash shall exceed $50,000 (or a lesser sum if the Company shall so request), unless otherwise provided by the terms of such series of Securities, that cash
shall be applied by the Trustee on the sinking fund Redemption Date with respect to Securities of such series next following the date of such payment to the redemption of Securities of such series at the applicable sinking fund Redemption Price with
respect to Securities of such series, together with accrued interest, if any, to the date fixed for redemption, with the effect provided in Section 11.06. The Trustee shall select, in the manner provided in Section 11.03, for redemption on such
sinking fund Redemption Date a sufficient principal amount of Securities of such series to utilize that cash and shall thereupon cause notice of redemption of the Securities of such series for the sinking fund to be given in the manner provided in
Section 11.04 (and with the effect provided in Section 11.06) for the redemption of Securities in part at the option of the Company. Any sinking fund moneys not so applied or allocated by the Trustee to the redemption of Securities of such
series shall be added to the next cash sinking fund payment with respect to Securities of such series received by the Trustee and, together with such payment, shall be applied in accordance with the provisions of this Section 11.08. Any and all
sinking fund moneys with respect to Securities of any series held by the Trustee at the Maturity of Securities of such series, and not held for the payment or redemption of particular Securities of such series, shall be applied by the Trustee,
together with other moneys, if necessary, to be deposited sufficient for the purpose, to the payment of the principal of the Securities of such series at Maturity. 

On or before each sinking fund Redemption Date provided with respect to Securities of any series, the Company shall pay to the Trustee in cash
a sum equal to all accrued interest, if any, to the date fixed for redemption on Securities to be redeemed on such sinking fund Redemption Date pursuant to this Section 11.08. 

SECTION 11.09 Rescission of Redemption. In the event that this Section 11.09 is specified to be applicable to a series of
Securities pursuant to Section 3.01 and a Redemption Rescission Event shall occur following any day on which a notice of redemption 

  
 56 

 
shall have been given pursuant to Section 11.04 hereof but at or prior to the time and date fixed for redemption as set forth in such notice of redemption, the Company may, at its sole option, at
any time prior to the earlier of (i) the close of business on that day that is two Trading Days following such Redemption Rescission Event and (ii) the time and date fixed for redemption as set forth in such notice, rescind the redemption to which
such notice of redemption shall have related by making a public announcement of such rescission (the date on which such public announcement shall have been made being hereinafter referred to as the “Rescission Date”). The Company
shall be deemed to have made such announcement if it shall issue a release to the Dow Jones News Service, Reuters Information Services or any successor news wire service. From and after the making of such announcement, the Company shall have no
obligation to redeem Securities called for redemption pursuant to such notice of redemption or to pay the Redemption Price therefor and all rights of Holders of Securities shall be restored as if such notice of redemption had not been given. As
promptly as practicable following the making of such announcement, the Company shall notify the Trustee and the Paying Agent telephonically and in writing of such rescission. The Company shall give notice of any such rescission by first-class mail,
postage prepaid, mailed as promptly as practicable but in no event later than the close of business on that day that is five Trading Days following the Rescission Date to each Holder of Securities at the close of business on the Rescission Date, to
any other Person that was a Holder of Securities and that shall have surrendered Securities for conversion following the giving of notice of the subsequently rescinded redemption and to the Trustee and the Paying Agent. Each notice of rescission
shall (w) state that the redemption described in the notice of redemption has been rescinded, (x) state that any Converting Holder shall be entitled to rescind the conversion of Securities surrendered for conversion following the day on which notice
of redemption was given but on or prior to the date of the mailing of the Company’s notice of rescission, (y) be accompanied by a form prescribed by the Company to be used by any Converting Holder rescinding the conversion of Securities so
surrendered for conversion (and instructions for the completion and delivery of such form, including instructions with respect to any payment that may be required to accompany such delivery) and (z) state that such form must be properly completed
and received by the Company no later than the close of business on a date that shall be 15 Trading Days following the date of the mailing of such notice of rescission. 

ARTICLE XII 

Conversion 

SECTION 12.01 Conversion Privilege. In the event that this Article XII is specified to be applicable to a series of Securities pursuant
to Section 3.01, the Holder of a Security of such series shall have the right, at such Holder’s option, to convert, in accordance with the terms of such series of Securities and this Article XII, all or any part (in a denomination of, unless
otherwise specified in a Board Resolution or indenture supplemental hereto with respect to Securities of such series, $2,000 or integral multiples of $1,000 in excess thereof) of such Security into shares of Common Stock or other Marketable
Securities specified in such Board Resolution or any indenture supplement hereto at any time or, as to any Securities called for redemption, at any time prior to the time and date fixed for such redemption (unless the Company shall default in the
payment of the Redemption Price, in which case such right shall not terminate at such time and date). 
 SECTION 12.02 Conversion
Procedure; Rescission of Conversion; Conversion Price; Fractional Shares. (a) Each Security to which this Article is 

  
 57 

 
applicable shall be convertible at the office of the Conversion Agent, and at such other place or places, if any, specified in a Board Resolution with respect to the Securities of such series,
into fully paid and nonassessable shares (calculated to the nearest 1/100th of a share) of Common Stock or other Marketable Securities. The Securities will be converted into shares of Common Stock or such other Marketable Securities at the
Conversion Price therefor. No payment or adjustment shall be made in respect of dividends on the Common Stock or such other Marketable Securities, or accrued interest on a converted Security except as described in Section 12.09. The
Company may, but shall not be required, in connection with any conversion of Securities, to issue a fraction of a share of Common Stock or of such other Marketable Security, and, if the Company shall determine not to issue any such fraction, the
Company shall, subject to Section 12.03(4), make a cash payment (calculated to the nearest cent) equal to such fraction multiplied by the Closing Price of the Common Stock or such other Marketable Security on the last Trading Day prior to the date
of conversion. 
 (b) Before any Holder of a Security shall be entitled to convert the same into Common Stock or other Marketable
Securities, such Holder shall surrender such Security duly endorsed to the Company or in blank, at the office of the Conversion Agent or at such other place or places, if any, specified in a Board Resolution or indenture supplemental hereto with
respect to the Securities of such series, and shall give written notice to the Company at said office or place that he elects to convert the same and shall state in writing therein the principal amount of Securities to be converted and the name or
names (with addresses) in which he wishes the certificate or certificates for Common Stock or for such other Marketable Securities to be issued; provided, however, that no Security or portion thereof shall be accepted for conversion
unless the principal amount of such Security or such portion, when added to the principal amount of all other Securities or portions thereof then being surrendered by the Holder thereof for conversion, exceeds the then effective Conversion Price
with respect thereto. If more than one Security shall be surrendered for conversion at one time by the same Holder, the number of full shares of Common Stock or such other Marketable Securities that shall be deliverable upon conversion shall be
computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof to the extent permitted thereby) so surrendered. Subject to the next succeeding sentence, the Company will, as soon as practicable
thereafter, issue and deliver at said office or place to such Holder of a Security, or to his nominee or nominees, certificates for the number of full shares of Common Stock or other Marketable Security to which he shall be entitled as aforesaid,
together, subject to the last sentence of paragraph (a) above, with cash in lieu of any fraction of a share to which he would otherwise be entitled. The Company shall not be required to deliver certificates for shares of Common Stock or other
Marketable Securities while the stock transfer books for such stock or the transfer books for such Marketable Securities, as the case may be, or the Security Register are duly closed for any purpose, but certificates for shares of Common Stock or
other Marketable Securities shall be issued and delivered as soon as practicable after the opening of such books or Security Register. A Security shall be deemed to have been converted as of the close of business on the date of the surrender of
such Security for conversion as provided above, and the person or persons entitled to receive the Common Stock or other Marketable Securities issuable upon such conversion shall be treated for all purposes as the record Holder or Holders of such
Common Stock or other Marketable Securities as of the close of business on such date. In case any Security shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon the
written order of the Holder of the Securities so surrendered, without charge to such Holder (subject to the provisions of Section 12.08), a new Security or Securities in authorized denominations in an aggregate principal amount equal to the
unconverted portion of the surrendered Security. 

  
 58 

 (c) Notwithstanding anything to the contrary contained herein, in the event the Company shall
have rescinded a redemption of Securities pursuant to Section 11.09 hereof, any Holder of Securities that shall have surrendered Securities for conversion following the day on which notice of the subsequently rescinded redemption shall have been
given but prior to the later of (a) the close of business on the Trading Day next succeeding the date on which public announcement of the rescission of such redemption shall have been made and (b) the date of the mailing of the notice of rescission
required by Section 11.09 hereof (a “Converting Holder”) may rescind the conversion of such Securities surrendered for conversion by (i) properly completing a form prescribed by the Company and mailed to Holders of Securities
(including Converting Holders) with the Company’s notice of rescission, which form shall provide for the certification by any Converting Holder rescinding a conversion on behalf of any beneficial owner (within the meaning of Rule 13d-3 under
the Securities Exchange Act of 1934) of Securities that the beneficial ownership (within the meaning of such Rule) of such Securities shall not have changed from the date on which such Securities were surrendered for conversion to the date of such
certification and (ii) delivering such form to the Company no later than the close of business on that date that is fifteen Trading Days following the date of the mailing of the Company’s notice of rescission. The delivery of such form by a
Converting Holder shall be accompanied by (x) any certificates representing shares of Common Stock or other securities issued to such Converting Holder upon a conversion of Securities that shall be rescinded by the proper delivery of such form (the
“Surrendered Securities”), (y) any securities, evidences of indebtedness or assets (other than cash) distributed by the Company to such Converting Holder by reason of such Converting Holder being a record holder of Surrendered
Securities and (z) payment in New York Clearing House funds or other funds acceptable to the Company of an amount equal to the sum of (I) any cash such Converting Holder may have received in lieu of the issuance of fractional Surrendered Securities
and (II) any cash paid or payable by the Company to such Converting Holder by reason of such Converting Holder being a record holder of Surrendered Securities. Upon receipt by the Company of any such form properly completed by a Converting Holder
and any certificates, securities, evidences of indebtedness, assets or cash payments required to be returned by such Converting Holder to the Company as set forth above, the Company shall instruct the transfer agent or agents for shares of Common
Stock or other securities to cancel any certificates representing Surrendered Securities (which Surrendered Securities shall be deposited in the treasury of the Company) and shall instruct the Registrar to reissue certificates representing
Securities to such Converting Holder (which Securities shall be deemed to have been outstanding at all times during the period following their surrender for conversion). The Company shall, as promptly as practicable, and in no event more than five
Trading Days following the receipt of any such properly completed form and any such certificates, securities, evidences of indebtedness, assets or cash payments required to be so returned, pay to the Holder of Securities surrendered to the Company
pursuant to a rescinded conversion or as otherwise directed by such Holder any interest paid or other payment made to Holders of Securities during the period from the time such Securities shall have been surrendered for conversion to the rescission
of such conversion. All questions as to the validity, form, eligibility (including time of receipt) and acceptance of any form submitted to the Company to rescind the conversion of Securities, including questions as to the proper completion or
execution of any such form or any certification contained therein, shall be resolved by the Company, whose determination shall be final and binding. 

SECTION 12.03 Adjustment of Conversion Price for Common Stock or Marketable Securities. The Conversion Price with respect to any
Security that is convertible into Common Stock or other Marketable Securities shall be adjusted from time to time as follows: 

  
 59 

 (1) In case the Company shall, at any time or from time to time while any of such
Securities are outstanding, (i) pay a dividend in shares of its Common Stock or other Marketable Securities, (ii) combine its outstanding shares of Common Stock or other Marketable Securities into a smaller number of shares or securities, (iii)
subdivide its outstanding shares of Common Stock or other Marketable Securities or (iv) issue by reclassification of its shares of Common Stock or other Marketable Securities any shares of stock or other Marketable Securities of the Company, then
the Conversion Price in effect immediately before such action shall be adjusted so that the Holders of such Securities, upon conversion thereof into Common Stock or other Marketable Securities immediately following such event, shall be entitled to
receive the kind and amount of shares of capital stock of the Company or other Marketable Securities which they would have owned or been entitled to receive upon or by reason of such event if such Securities had been converted immediately before the
record date (or, if no record date, the effective date) for such event. An adjustment made pursuant to this Section 12.03(1) shall become effective retroactively immediately after the record date in the case of a dividend or distribution and shall
become effective retroactively immediately after the effective date in the case of a subdivision, combination or reclassification. For the purposes of this Section 12.03(1), each Holder of Securities shall be deemed to have failed to exercise
any right to elect the kind or amount of securities receivable upon the payment of any such dividend, subdivision, combination or reclassification (provided that if the kind or amount of securities receivable upon such dividend, subdivision,
combination or reclassification is not the same for each nonelecting share, then the kind and amount of securities or other property receivable upon such dividend, subdivision, combination or reclassification for each nonelecting share shall be
deemed to be the kind and amount so receivable per share by a plurality of the nonelecting shares). 
 (2) In case the
Company shall, at any time or from time to time while any of such Securities are outstanding, issue rights or warrants to all holders of shares of its Common Stock or other Marketable Securities entitling them (for a period expiring within 45 days
after the record date for such issuance) to subscribe for or purchase shares of Common Stock or other Marketable Securities (or securities convertible into shares of Common Stock or other Marketable Securities) at a price per share less than the
Current Market Price of the Common Stock or other Marketable Securities at such record date (treating the price per share of the securities convertible into Common Stock or other Marketable Securities as equal to (x) the sum of (i) the price for a
unit of the security convertible into Common Stock or other Marketable Securities plus (ii) any additional consideration initially payable upon the conversion of such security into Common Stock or other Marketable Securities divided by (y) the
number of shares of Common Stock or other Marketable Securities initially underlying such convertible security), the Conversion Price with respect to such Securities shall be adjusted so that it shall equal the price determined by dividing the
Conversion Price in effect immediately prior to the date of issuance of such rights or warrants by a fraction, the numerator of which shall be the number of shares of Common Stock or other Marketable Securities outstanding on the date of issuance of
such rights or warrants plus the number of additional shares of Common Stock or other Marketable Securities offered for subscription or purchase (or into which the convertible securities so offered are initially convertible), and the denominator of
which shall be the number of shares of Common Stock or other Marketable Securities outstanding on the date of issuance of such rights or warrants plus the number of shares or securities that the aggregate offering price of the total number of shares
or securities so offered for subscription or purchase (or the aggregate purchase price of the convertible securities so offered plus the aggregate amount of any additional 

  
 60 

 
consideration initially payable upon conversion of such Securities into Common Stock or other Marketable Securities) would purchase at such Current Market Price of the Common Stock or other
Marketable Securities. Such adjustment shall become effective retroactively immediately after the record date for the determination of stockholders entitled to receive such rights or warrants. 

(3) In case the Company shall, at any time or from time to time while any of such Securities are outstanding, distribute to all
holders of shares of its Common Stock or other Marketable Securities (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing corporation and the Common Stock or other Marketable
Securities are not changed or exchanged) cash, evidences of its indebtedness, securities or assets (excluding (i) regular periodic cash dividends in amounts, if any, determined from time to time by the Board of Directors, (ii) in dividends payable
in shares of Common Stock or other Marketable Securities for which adjustment is made under Section 12.03(1) or (iii) rights or warrants to subscribe for or purchase securities of the Company (excluding those referred to in Section 12.03(2)),
then in each such case the Conversion Price with respect to such Securities shall be adjusted so that it shall equal the price determined by dividing the Conversion Price in effect immediately prior to the date of such distribution by a fraction,
the numerator of which shall be the Current Market Price of the Common Stock or other Marketable Securities on the record date referred to below, and the denominator of which shall be such Current Market Price of the Common Stock or other Marketable
Securities less the then fair market value (as determined by the Board of Directors of the Company, whose determination shall be conclusive) of the portion of the cash or assets or evidences of indebtedness or securities so distributed or of such
subscription rights or warrants applicable to one share of Common Stock or one other Marketable Security (provided that such denominator shall never be less than 1.0); provided, however, that no adjustment shall be made with
respect to any distribution of rights to purchase securities of the Company if a Holder of Securities would otherwise be entitled to receive such rights upon conversion at any time of such Securities into Common Stock or other Marketable Securities
unless such rights are subsequently redeemed by the Company, in which case such redemption shall be treated for purposes of this Section as a dividend on the Common Stock or other Marketable Securities. Such adjustment shall become effective
retroactively immediately after the record date for the determination of stockholders or holders of Marketable Securities entitled to receive such distribution; and in the event that such distribution is not so made, the Conversion Price shall again
be adjusted to the Conversion Price that would then be in effect if such record date had not been fixed. 
 (4) The Company
shall be entitled to make such additional adjustments in the Conversion Price, in addition to those required by subsections 12.03(1), 12.03(2) and 12.03(3), as shall be necessary in order that any dividend or distribution of Common Stock or other
Marketable Securities, any subdivision, reclassification or combination of shares of Common Stock or other Marketable Securities or any issuance of rights or warrants referred to above shall not be taxable to the holders of Common Stock or other
Marketable Securities for United States Federal income tax purposes. 
 (5) In any case in which this Section 12.03 shall
require that any adjustment be made effective as of or retroactively immediately following a record date, the Company may elect to defer (but only for five (5) Trading Days following the filing of the statement referred to in Section 12.05) issuing
to the Holder of any Securities 

  
 61 

 
converted after such record date the shares of Common Stock and other capital stock of the Company or other Marketable Securities issuable upon such conversion over and above the shares of Common
Stock and other capital stock of the Company or other Marketable Securities issuable upon such conversion on the basis of the Conversion Price prior to adjustment; provided, however, that the Company shall deliver to such Holder a due
bill or other appropriate instrument evidencing such Holder’s right to receive such additional shares upon the occurrence of the event requiring such adjustment. 

(6) All calculations under this Section 12.03 shall be made to the nearest cent or one-hundredth of a share or security, with
one-half cent and .005 of a share, respectively, being rounded upward. Notwithstanding any other provision of this Section 12.03, the Company shall not be required to make any adjustment of the Conversion Price unless such adjustment would require
an increase or decrease of at least 1% of such price. Any lesser adjustment shall be carried forward and shall be made at the time of and together with the next subsequent adjustment that, together with any adjustment or adjustments so carried
forward, shall amount to an increase or decrease of at least 1% in such price. Any adjustments under this Section 12.03 shall be made successively whenever an event requiring such an adjustment occurs. 

(7) In the event that at any time, as a result of an adjustment made pursuant to this Section 12.03, the Holder of any Security
thereafter surrendered for conversion shall become entitled to receive any shares of stock of or other Marketable Securities of the Company other than shares of Common Stock or Marketable Securities into which the Securities originally were
convertible, the Conversion Price of such other shares or Marketable Securities so receivable upon conversion of any such Security shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the
provisions with respect to Common Stock and Marketable Securities contained in subparagraphs (1) through (6) of this Section 12.03, and the provision of Sections 12.01, 12.02 and 12.04 through 12.09 with respect to the Common Stock or other
Marketable Securities shall apply on like or similar terms to any such other shares or Marketable Securities and the determination of the Board of Directors as to any such adjustment shall be conclusive. 

(8) No adjustment shall be made pursuant to this Section (i) if the effect thereof would be to reduce the Conversion Price
below the par value (if any) of the Common Stock or other Marketable Security, if any, or (ii) subject to Section 12.03(5) hereof, with respect to any Security that is converted prior to the time such adjustment otherwise would be made. 

SECTION 12.04 Consolidation or Merger of the Company. In case of either (a) any consolidation or merger to which the Company is a
party, other than a merger or consolidation in which the Company is the surviving or continuing corporation and that does not result in a reclassification of, or change (other than a change in par value or from par value to no par value or from no
par value to par value, as a result of a subdivision or combination) in, outstanding shares of Common Stock or other Marketable Securities or (b) any sale or conveyance of all or substantially all of the property and assets of the Company to another
Person, then each Security then Outstanding shall be convertible from and after such merger, consolidation, sale or conveyance of property and assets into the kind and amount of shares of stock or other securities and property (including cash)
receivable upon such consolidation, merger, sale or conveyance by a holder of the number of shares of Common Stock or other Marketable Securities into which such Securities would have been converted immediately prior to

  
 62 

 
such consolidation, merger, sale or conveyance, subject to adjustments that shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article XII (and assuming
such holder of Common Stock or other Marketable Securities failed to exercise his rights of election, if any, as to the kind or amount of securities, cash or other property (including cash) receivable upon such consolidation, merger, sale or
conveyance (provided that, if the kind or amount of securities, cash or other property (including cash) receivable upon such consolidation, merger, sale or conveyance is not the same for each nonelecting share, then the kind and amount of
securities, cash or other property (including cash) receivable upon such consolidation, merger, sale or conveyance for each nonelecting share, shall be deemed to be the kind and amount so receivable per share by a plurality of the nonelecting shares
or securities)). The Company shall not enter into any of the transactions referred to in clause (a) or (b) of the preceding sentence unless effective provision shall be made so as to give effect to the provisions set forth in this Section
12.04. The provisions of this Section 12.04 shall apply similarly to successive consolidations, mergers, sales or conveyances. 

SECTION 12.05 Notice of Adjustment. Whenever an adjustment in the Conversion Price with respect to a series of Securities is
required: 
 (1) the Company shall forthwith place on file with the Trustee and any Conversion Agent for such Securities a
certificate of the Treasurer of the Company, stating the adjusted Conversion Price determined as provided herein and setting forth in reasonable detail such facts as shall be necessary to show the reason for and the manner of computing such
adjustment, such certificate to be conclusive evidence that the adjustment is correct; and 
 (2) a notice stating that the
Conversion Price has been adjusted and setting forth the adjusted Conversion Price shall forthwith be mailed, first class postage prepaid, by the Company to the Holders of record of such Outstanding Securities. 

SECTION 12.06 Notice in Certain Events. In case: 

(1) of a consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is
required, or of the sale or conveyance to another person or entity or group of persons or entities acting in concert as a partnership, limited partnership, syndicate or other group (within the meaning of Rule 13d-3 under the Securities Exchange Act
of 1934) of all or substantially all of the property and assets of the Company; or 
 (2) of the voluntary or involuntary
dissolution, liquidation or winding up of the Company; or 
 (3) of any action triggering an adjustment of the Conversion
Price pursuant to this Article XII; 
 then, in each case, the Company shall cause to be filed with the Trustee and the Agent for the applicable Securities,
and shall cause to be mailed, first class postage prepaid, to the Holders of record of applicable Securities, at least fifteen (15) days prior to the applicable date hereinafter specified, a notice stating (x) the date on which a record is to be
taken for the purpose of any distribution or grant of rights or warrants triggering an adjustment to the Conversion Price pursuant to this Article XII, or, if a record is not to be taken, the date as of which the holders of record of Common Stock or
other Marketable Securities entitled to such distribution, rights or 

  
 63 

 
warrants are to be determined, or (y) the date on which any reclassification, consolidation, merger, sale, conveyance, dissolution, liquidation or winding up triggering an adjustment to the
Conversion Price pursuant to this Article XII is expected to become effective, and the date as of which it is expected that holders of Common Stock or other Marketable Securities of record shall be entitled to exchange their Common Stock or other
Marketable Securities for securities or other property deliverable upon such reclassification, consolidation, merger, sale, conveyance, dissolution, liquidation or winding up. 

Failure to give such notice or any defect therein shall not affect the legality or validity of the proceedings described in clause (1), (2) or
(3) of this Section. 
 SECTION 12.07 Company to Reserve Stock or other Marketable Securities; Registration; Listing. (a) The
Company shall at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued shares of Common Stock or other Marketable Securities, for the purpose of effecting the conversion of the Securities, such number
of its duly authorized shares of Common Stock or number or principal amount of other Marketable Securities as shall from time to time be sufficient to effect the conversion of all applicable outstanding Securities into such Common Stock or other
Marketable Securities at any time (assuming that, at the time of the computation of such number of shares or securities, all such Securities would be held by a single Holder); provided, however, that nothing contained herein shall
preclude the Company from satisfying its obligations in respect of the conversion of the Securities by delivery of purchased shares of Common Stock or other Marketable Securities that are held in the treasury of the Company. The Company shall from
time to time, in accordance with the laws of the State of Delaware, use its commercially reasonable efforts to cause the authorized amount of the Common Stock or other Marketable Securities to be increased if the aggregate of the authorized amount
of the Common Stock or other Marketable Securities remaining unissued and the issued shares of such Common Stock or other Marketable Securities in its treasury (other than any such shares reserved for issuance in any other connection) shall not be
sufficient to permit the conversion of all Securities. 
 (b) If any shares of Common Stock or other Marketable Securities that would be
issuable upon conversion of Securities hereunder require registration with or approval of any governmental authority before such shares or securities may be issued upon such conversion, the Company will in good faith and as expeditiously as possible
endeavor to cause such shares or securities to be duly registered or approved, as the case may be. The Company will endeavor to list the shares of Common Stock or other Marketable Securities required to be delivered upon conversion of the Securities
prior to such delivery upon the principal national securities exchange upon which the outstanding Common Stock or other Marketable Securities is listed at the time of such delivery. 

SECTION 12.08 Taxes on Conversion. The Company shall pay any and all documentary, stamp or similar issue or transfer taxes that
may be payable in respect of the issue or delivery of shares of Common Stock or other Marketable Securities on conversion of Securities pursuant hereto. The Company shall not, however, be required to pay any such tax that may be payable in
respect of any transfer involved in the issue or delivery of shares of Common Stock or other Marketable Securities or the portion, if any, of the Securities that are not so converted in a name other than that in which the Securities so converted
were registered, and no such issue or delivery shall be made unless and until the person requesting such issue has paid to the Company the amount of such tax or has established to the satisfaction of the Company that such tax has been paid. 

  
 64 

 SECTION 12.09 Conversion After Record Date. If any Securities are surrendered for
conversion subsequent to the record date preceding an Interest Payment Date but on or prior to such Interest Payment Date (except Securities called for redemption on a Redemption Date between such record date and Interest Payment Date), the Holder
of such Securities at the close of business on such record date shall be entitled to receive the interest payable on such securities on such Interest Payment Date notwithstanding the conversion thereof. Securities surrendered for conversion
during the period from the close of business on any record date next preceding any Interest Payment Date to the opening of business on such Interest Payment Date shall (except in the case of Securities that have been called for redemption on a
Redemption Date within such period) be accompanied by payment in New York Clearing House funds or other funds acceptable to the Company of an amount equal to the interest payable on such Interest Payment Date on the Securities being surrendered for
conversion. Except as provided in this Section 12.09, no adjustments in respect of payments of interest on Securities surrendered for conversion or any dividends or distributions or interest on the Common Stock or other Marketable Securities issued
upon conversion shall be made upon the conversion of any Securities. 
 SECTION 12.10 Corporate Action Regarding Par Value of Common
Stock. Before taking any action that would cause an adjustment reducing the applicable Conversion Price below the then par value (if any) of the shares of Common Stock or other Marketable Securities deliverable upon conversion of the
Securities, the Company will take any corporate action that may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue fully paid and nonassessable shares of Common Stock or other Marketable Securities
at such adjusted Conversion Price. 
 SECTION 12.11 Company Determination Final. Any determination that the Company or the Board
of Directors must make pursuant to this Article is conclusive. 
 SECTION 12.12 Trustee’s Disclaimer. The Trustee has no
responsibility or liability for any calculations made by the Company with respect to the conversion of any Securities hereunder and has no duty to determine when an adjustment under this Article should be made, how it should be made or what it
should be. The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of Securities. The Trustee shall not be responsible for the Company’s failure to comply with this Article. Each
Conversion Agent other than the Company shall have the same protection under this Section as the Trustee.
