2.2.22 any other terms of the Series (which may supplement, modify or delete any provision of this Indenture insofar as it applies to such
Series), including any terms that may be required under applicable law or regulations or advisable in connection with the marketing of Securities of that Series. 

  
 8 

 All Securities of any one Series need not be issued at the same time and may be issued from
time to time, consistent with the terms of this Indenture, if so provided by or pursuant to the Board Resolution, supplemental indenture hereto or Officer’s Certificate referred to above. 

2.3 Execution and Authentication. An Officer shall sign the Securities for the Company by manual or facsimile signature. 

If an Officer whose signature is on a Security no longer holds that office at the time the Security is authenticated, the Security shall
nevertheless be valid. 
 A Security shall not be valid until authenticated by the manual or facsimile signature of the Trustee or an
authenticating agent. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture. 
 The
Trustee shall at any time, and from time to time, authenticate Securities for original issue in the principal amount provided in the Board Resolution, supplemental indenture hereto or Officer’s Certificate, upon receipt by the Trustee of a
Company Order. Each Security shall be dated the date of its authentication. 
 The aggregate principal amount of Securities of any Series
outstanding at any time may not exceed any limit upon the maximum principal amount for such Series set forth in the Board Resolution, supplemental indenture hereto or Officer’s Certificate delivered pursuant to Section 2.2, except as
provided in Section 2.8. 
 Prior to the issuance of Securities of any Series, the Trustee shall have received and (subject to
Section 7.2) shall be fully protected in relying on: (a) the Board Resolution, supplemental indenture hereto or Officer’s Certificate establishing the form of the Securities of that Series or of Securities within that Series and the
terms of the Securities of that Series or of Securities within that Series, (b) an Officer’s Certificate complying with Section 10.4, and (c) an Opinion of Counsel complying with Section 10.4. 

The Trustee shall have the right to decline to authenticate and deliver any Securities of such Series: (a) if the Trustee, being advised
by counsel, determines that such action may not be taken lawfully; or (b) if the Trustee in good faith by its board of directors or trustees, executive committee or a trust committee of directors and/or vice-presidents or a committee of
Responsible Officers shall determine that such action would expose the Trustee to personal liability to Holders of any then outstanding Series of Securities. 

  
 9 

 The Trustee may appoint an authenticating agent acceptable to the Company to authenticate
Securities. An authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as
an Agent to deal with the Company or an Affiliate of the Company. 
 2.4 Registrar and Paying Agent. The Company shall maintain, with
respect to each Series of Securities, at the place or places specified with respect to such Series pursuant to Section 2.2, an office or agency where Securities of such Series may be presented or surrendered for payment (“Paying
Agent”), where Securities of such Series may be surrendered for registration of transfer or exchange (“Registrar”) and where notices and demands to or upon the Company in respect of the Securities of such Series and this
Indenture may be delivered (“Notice Agent”). The Registrar shall keep a register with respect to each Series of Securities and to their transfer and exchange. The Company will give prompt written notice to the Trustee of the name
and address, and any change in the name or address, of each Registrar, Paying Agent or Notice Agent. If at any time the Company shall fail to maintain any such required Registrar, Paying Agent or Notice Agent or shall fail to furnish the Trustee
with the name and 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. 
 The Company may also from time to time designate one or more
co-registrars, additional paying agents or additional notice agents 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 obligations to maintain a Registrar, Paying Agent and Notice Agent in each place so specified pursuant to Section 2.2 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 name or address of any such co-registrar, additional paying agent or additional notice agent. The term “Registrar”
includes any co-registrar; the term “Paying Agent” includes any additional paying agent; and the term “Notice Agent” includes any additional notice agent. The Company or any
of its Affiliates may serve as Registrar or Paying Agent. 
 The Company hereby appoints the Trustee the initial Registrar, Paying Agent and
Notice Agent for each Series unless another Registrar, Paying Agent or Notice Agent, as the case may be, is appointed prior to the time Securities of that Series are first issued. 

2.5 Paying Agent to Hold Money in Trust. The Company shall require each Paying Agent other than the Trustee to agree in writing that the
Paying Agent will hold in trust, for the benefit of Securityholders of any Series of Securities, or the Trustee, all money held by the Paying Agent for the payment of principal of or interest on the Series of Securities, and will notify the Trustee
in writing of any default by the Company in making any such payment. While any such default continues, the Trustee may require a 

  
 10 

 
Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the
Paying Agent (if other than the Company or a Subsidiary of the Company) shall have no further liability for the money. If the Company or a Subsidiary of the Company acts as Paying Agent, it shall segregate and hold in a separate trust fund for the
benefit of Securityholders of any Series of Securities all money held by it as Paying Agent. Upon any bankruptcy, reorganization or similar proceeding with respect to the Company, the Trustee shall serve as Paying Agent for the Securities. 

2.6 Securityholder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to
it of the names and addresses of Securityholders of each Series of Securities and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, the Company shall furnish to the Trustee at least ten days before each interest
payment date and at such other times as the Trustee may request in writing a list, in such form and as of such date as the Trustee may reasonably require, of the names and addresses of Securityholders of each Series of Securities. 

2.7 Transfer and Exchange. Where Securities of a Series are presented to the Registrar or a
co-registrar with a request to register a transfer or to exchange them for an equal principal amount of Securities of the same Series, the Registrar shall register the transfer or make the exchange if its
requirements for such transactions are met. To permit registrations of transfers and exchanges, the Trustee shall authenticate Securities at the Registrar’s request. No service charge shall be made for any registration of transfer or exchange
(except as otherwise expressly permitted herein), but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer tax or similar
governmental charge payable upon exchanges pursuant to Sections 2.11, 3.6 or 9.6). 
 Neither the Company nor the Registrar shall be
required (a) to issue, register the transfer of, or exchange Securities of any Series for the period beginning at the opening of business fifteen days immediately preceding the mailing of a notice of redemption of Securities of that Series
selected for redemption and ending at the close of business on the day of such mailing, or (b) to register the transfer of or exchange Securities of any Series selected, called or being called for redemption as a whole or the portion being
redeemed of any such Securities selected, called or being called for redemption in part. 
 2.8 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. 

  
 11 

 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 bond as may be required by each of them to hold itself and any of its agents 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 upon its request the Trustee shall authenticate and make available for delivery, in lieu of any such destroyed, lost or stolen Security, a new
Security of the same Series and of like tenor and principal amount and bearing a number not contemporaneously outstanding. 
 In case any
such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security. 

Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. 

Every new Security of any Series issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an
original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities of that Series duly issued hereunder. 
 The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. 

2.9 Outstanding Securities. The Securities outstanding at any time are all the Securities authenticated by the Trustee except for those
canceled by it, those delivered to it for cancellation, those reductions in the interest on a Global Security effected by the Trustee in accordance with the provisions hereof and those described in this Section as not outstanding. 

If a Security is replaced pursuant to Section 2.8, it ceases to be outstanding until the Trustee receives proof satisfactory to it that
the replaced Security is held by a bona fide purchaser. 
 If the Paying Agent (other than the Company, a Subsidiary of the Company or an
Affiliate of the Company) holds on the Maturity of Securities of a Series money sufficient to pay such Securities payable on that date, then on and after that date such Securities of the Series cease to be outstanding and interest on them ceases to
accrue. 

  
 12 

 The Company may purchase or otherwise acquire the Securities, whether by open market
purchases, negotiated transactions or otherwise. A Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security. 

In determining whether the Holders of the requisite principal amount of outstanding Securities have given any request, demand, authorization,
direction, notice, consent or waiver hereunder, the principal amount of a Discount Security that shall be deemed to be outstanding for such purposes shall be the amount of the principal thereof that would be due and payable as of the date of such
determination upon a declaration of acceleration of the Maturity thereof pursuant to Section 6.2. 
 2.10 Treasury Securities. In
determining whether the Holders of the required principal amount of Securities of a Series have concurred in any request, demand, authorization, direction, notice, consent or waiver, Securities of a Series owned by the Company or any Affiliate of
the Company shall be disregarded, except that for the purposes of determining whether the Trustee shall be protected in relying on any such request, demand, authorization, direction, notice, consent or waiver only Securities of a Series that a
Responsible Officer of the Trustee knows are so owned shall be so disregarded. 
 2.11 Temporary Securities. Until definitive
Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities upon a Company Order. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that
the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee upon receipt of a Company Order shall authenticate definitive Securities of the same Series and date of maturity in
exchange for temporary Securities. Until so exchanged, temporary securities shall have the same rights under this Indenture as the definitive Securities. 

2.12 Cancellation. The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying Agent
shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee shall cancel all Securities surrendered for transfer, exchange, payment, replacement or cancellation and shall destroy
such canceled Securities (subject to the record retention requirement of the Exchange Act and the Trustee) and deliver a certificate of such cancellation to the Company upon written request of the Company. The Company may not issue new Securities to
replace Securities that it has paid or delivered to the Trustee for cancellation. 
 2.13 Defaulted Interest. If the Company defaults
in a payment of interest on a Series of Securities, it shall pay the defaulted interest, plus, to the extent permitted by law, any interest payable on the defaulted interest, to the persons who are Securityholders of the Series on a subsequent
special record date. The Company shall fix the record date and payment date. At least 10 days before the special record date, the Company shall mail to the Trustee and to each Securityholder of the Series a notice that states the special record
date, the payment date and the amount of interest to be paid. The Company may pay defaulted interest in any other lawful manner. 

  
 13 

 2.14 Global Securities. 

2.14.1 Terms of Securities. A Board Resolution, a supplemental indenture hereto or an Officer’s Certificate shall establish whether
the Securities of a Series shall be issued in whole or in part in the form of one or more Global Securities and the Depositary for such Global Security or Securities. 

2.14.2 Transfer and Exchange. Notwithstanding any provisions to the contrary contained in Section 2.7 of the Indenture and in
addition thereto, any Global Security shall be exchangeable pursuant to Section 2.7 of the Indenture for Securities registered in the names of Holders other than the Depositary for such Security or its nominee only if (i) such Depositary
notifies the Company that it is unwilling or unable to continue as Depositary for such Global Security or if at any time such Depositary ceases to be a clearing agency registered under the Exchange Act, and, in either case, the Company fails to
appoint a successor Depositary registered as a clearing agency under the Exchange Act within 90 days of such event or (ii) the Company executes and delivers to the Trustee an Officer’s Certificate to the effect that such Global Security
shall be so exchangeable. Any Global Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for Securities registered in such names as the Depositary shall direct in writing in an aggregate principal amount equal to
the principal amount of the Global Security with like tenor and terms. 
 Except as provided in this Section 2.14.2, a Global Security
may not be transferred except as a whole by the Depositary with respect to such Global Security to a nominee of such Depositary, by a nominee of such Depositary to such Depositary or another nominee of such Depositary or by the Depositary or any
such nominee to a successor Depositary or a nominee of such a successor Depositary. 
 2.14.3 Legend. Any Global Security issued
hereunder shall bear a legend in substantially the following form: 
 “This Security is a Global Security within the meaning of the
Indenture hereinafter referred to and is registered in the name of the Depositary or a nominee of the Depositary. This Security is exchangeable for Securities registered in the name of a person other than the Depositary or its nominee only in the
limited circumstances described in the Indenture, and may not be transferred except as a whole by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the
Depositary or any such nominee to a successor Depositary or a nominee of such a successor Depositary.” 

  
 14 

 2.14.4 Acts of Holders. The Depositary, as a Holder, may appoint agents and otherwise
authorize participants to give or take any request, demand, authorization, direction, notice, consent, waiver or other action which a Holder is entitled to give or take under the Indenture. 

2.14.5 Payments. Notwithstanding the other provisions of this Indenture, unless otherwise specified as contemplated by Section 2.2,
payment of the principal of and interest, if any, on any Global Security shall be made to the Holder thereof. 
 2.14.6 Consents,
Declaration and Directions. The Company, the Trustee and any Agent shall treat a person as the Holder of such principal amount of outstanding Securities of such Series represented by a Global Security as shall be specified in a written statement
of the Depositary or by the applicable procedures of such Depositary with respect to such Global Security, for purposes of obtaining any consents, declarations, waivers or directions required to be given by the Holders pursuant to this Indenture.

 2.15 CUSIP Numbers. The Company in issuing the Securities may use “CUSIP” numbers (if then generally in use), and, if so,
the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the
Securities or as contained in any notice of a redemption and that reliance may be placed only on the other elements of identification printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such
numbers. 
 ARTICLE III 

REDEMPTION 
 3.1 Notice to
Trustee. The Company may, with respect to any Series of Securities, reserve the right to redeem and pay the Series of Securities or may covenant to redeem and pay the Series of Securities or any part thereof prior to the Stated Maturity thereof
at such time and on such terms as provided for in such Securities. If a Series of Securities is redeemable and the Company wants or is obligated to redeem prior to the Stated Maturity thereof all or part of the Series of Securities pursuant to the
terms of such Securities, it shall notify the Trustee in writing of the redemption date and the principal amount of Series of Securities to be redeemed. The Company shall give the notice at least 15 days before the redemption date. 

  
 15 

 3.2 Selection of Securities to be Redeemed. Unless otherwise indicated for a
particular Series by a Board Resolution, a supplemental indenture hereto or an Officer’s Certificate, if less than all the Securities of a Series are to be redeemed, the Trustee shall select the Securities of the Series to be redeemed in any
manner that the Trustee deems fair and appropriate, including by lot or other method, unless otherwise required by law or applicable stock exchange requirements, subject, in the case of Global Securities, to the applicable rules and procedures of
the Depositary. The Trustee shall make the selection from Securities of the Series outstanding not previously called for redemption. The Trustee may select for redemption portions of the principal of Securities of the Series that have denominations
larger than $1,000. Securities of the Series and portions of them it selects shall be in amounts of $1,000 or whole multiples of $1,000 or, with respect to Securities of any Series issuable in other denominations pursuant to Section 2.2.10, the
minimum principal denomination for each Series and the authorized integral multiples thereof. Provisions of this Indenture that apply to Securities of a Series called for redemption also apply to portions of Securities of that Series called for
redemption. 
 3.3 Notice of Redemption. Unless otherwise indicated for a particular Series by Board Resolution, a supplemental
indenture hereto or an Officer’s Certificate, at least 15 days but not more than 60 days before a redemption date, the Company shall mail a notice of redemption by first-class mail to each Holder whose Securities are to be redeemed. 

The notice shall identify the Securities of the Series to be redeemed and shall state: 

(a) the redemption date; 

(b) the redemption price; 

(c) the name and address of the Paying Agent; 

(d) if any Securities are being redeemed in part, the portion of the principal amount of such Securities to be redeemed and
that, after the redemption date and upon surrender of such Security, a new Security or Securities in principal amount equal to the unredeemed portion of the original Security shall be issued in the name of the Holder thereof upon cancellation of the
original Security; 
 (e) that Securities of the Series called for redemption must be surrendered to the Paying Agent to
collect the redemption price; 
 (f) that interest on Securities of the Series called for redemption ceases to accrue on and
after the redemption date unless the Company defaults in the deposit of the redemption price; 

  
 16 

 (g) the CUSIP number, if any; and 

(h) any other information as may be required by the terms of the particular Series or the Securities of a Series being
redeemed. 
 At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at its expense,
provided, however, that the Company has delivered to the Trustee, at least 10 days (unless a shorter time shall be acceptable to the Trustee) prior to the notice date, an Officer’s Certificate requesting that the Trustee give such
notice and setting forth the information to be stated in such notice. 
 3.4 Effect of Notice of Redemption. Once notice of redemption
is mailed as provided in Section 3.3, Securities of a Series called for redemption become due and payable on the redemption date and at the redemption price. Except as otherwise provided in the supplemental indenture, Board Resolution or
Officer’s Certificate for a Series, a notice of redemption may not be conditional. Upon surrender to the Paying Agent, such Securities shall be paid at the redemption price plus accrued interest to the redemption date. 

3.5 Deposit of Redemption Price. On or before 11:00 a.m., New York City time, on the redemption date, the Company shall deposit with the
Paying Agent money sufficient to pay the redemption price of and accrued interest, if any, on all Securities to be redeemed on that date. 

3.6 Securities Redeemed in Part. Upon surrender of a Security that is redeemed in part, the Trustee shall authenticate for the Holder a
new Security of the same Series and the same maturity equal in principal amount to the unredeemed portion of the Security surrendered. 

ARTICLE IV 
 COVENANTS 

4.1 Payment of Principal and Interest. The Company covenants and agrees for the benefit of the Holders of each Series of Securities
that it will duly and punctually pay the principal of and interest, if any, on the Securities of that Series in accordance with the terms of such Securities and this Indenture. On or before 11:00 a.m., New York City time, on the applicable payment
date, the Company shall deposit with the Paying Agent money sufficient to pay the principal of and interest, if any, on the Securities of each Series in accordance with the terms of such Securities and this Indenture. 

  
 17 

 4.2 SEC Reports. To the extent any Securities of a Series are outstanding, the
Company shall deliver to the Trustee within 15 days after it files them with the SEC copies of the annual reports and of the information, documents, and other reports (or copies of such portions of any of the foregoing as the SEC may by rules and
regulations prescribe) which the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act. The Company also shall comply with the other provisions of TIA § 314(a). Reports, information and documents
filed with the SEC via the EDGAR system will be deemed to be delivered to the Trustee as of the time of such filing via EDGAR for purposes of this Section 4.2. 

Delivery of reports, information and documents to the Trustee under this Section 4.2 are for informational purposes only and the
Trustee’s receipt of the foregoing shall not constitute constructive or actual 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 exclusively on Officer’s Certificates). 
 4.3 Compliance Certificate. To
the extent any Securities of a Series are outstanding, the Company shall deliver to the Trustee, within 120 days after the end of each fiscal year of the Company, an Officer’s Certificate stating that a review of the activities of the Company
and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Company has kept, observed, performed and fulfilled its obligations under this Indenture, and
further stating, as to each such Officer signing such certificate, that to the best of his/her knowledge the Company has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and is not in default in the
performance or observance of any of the terms, provisions and conditions hereof (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which the Officer may have knowledge). 

The Company will, so long as any of the Securities are outstanding, deliver to the Trustee, promptly upon becoming aware of any Default or
Event of Default, an Officer’s Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect thereto. 

4.4 Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist
upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture or the
Securities; and the Company (to the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not, by resort to any such law, 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 has been enacted. 

  
 18 

 4.5 Corporate Existence. Subject to Article V, the Company will do or cause to be
done all things necessary to preserve and keep in full force and effect its corporate existence and rights (charter and statutory); provided, however, that the Company shall not be required to preserve any such right if the Board of
Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries taken as a whole and that the loss thereof is not adverse in any material respect to the Holders. 

ARTICLE V 
 SUCCESSORS 

5.1 When Company May Merge, Etc. The Company shall not consolidate with or merge with or into, or convey, transfer or lease all or
substantially all of its properties and assets to, any person (a “successor person”) unless: 
 (a) the
Company is the surviving corporation or the successor person (if other than the Company) is a corporation organized and validly existing under the laws of any U.S. domestic jurisdiction and expressly assumes the Company’s obligations on the
Securities and under this Indenture; and 
 (b) immediately after giving effect to the transaction, no Default or Event of
Default, shall have occurred and be continuing. 
 The Company shall deliver to the Trustee prior to the consummation of the proposed
transaction an Officer’s Certificate to the foregoing effect and an Opinion of Counsel stating that the proposed transaction and any supplemental indenture comply with this Indenture. 

Notwithstanding the above, any Subsidiary of the Company may consolidate with, merge into or transfer all or part of its properties to the
Company. Neither an Officer’s Certificate nor an Opinion of Counsel shall be required to be delivered in connection therewith. 
 5.2
Successor Corporation Substituted. Upon any consolidation or merger, or any sale, lease, conveyance or other disposition of all or substantially all of the assets of the Company in accordance with Section 5.1, the successor corporation
formed by such consolidation or into or with which the Company is merged or to which such sale, lease, conveyance or other disposition is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under
this Indenture with the same effect as if such successor person has been named as the Company herein; provided, however, that the predecessor Company in the case of a sale, conveyance or other disposition (other than a lease) shall be
released from all obligations and covenants under this Indenture and the Securities. 

  
 19 

 ARTICLE VI 

DEFAULTS AND REMEDIES 
 6.1
Events of Default. “Event of Default,” wherever used herein with respect to Securities of any Series, means any one of the following events, unless in the establishing Board Resolution, supplemental indenture or
Officer’s Certificate, it is provided that such Series shall not have the benefit of said Event of Default: 

(a) default in the payment of any interest on any Security of that Series when it becomes due and payable, and continuance of
such default for a period of 30 days (unless the entire amount of such payment is deposited by the Company with the Trustee or with a Paying Agent prior to 11:00 a.m., New York City time, on the 30th day of such period); or 

(b) default in the payment of principal of any Security of that Series at its Maturity; or 

(c) default in the performance or breach of any covenant or warranty of the Company in this Indenture (other than defaults
pursuant to paragraphs (a) or (b) above or pursuant to a covenant or warranty that has been included in this Indenture solely for the benefit of Series of Securities other than that Series), which default continues uncured for a period of 60
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 principal amount of the outstanding Securities of that 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 

(d) the Company pursuant to or within the meaning of any Bankruptcy Law: 

(i) commences a voluntary case, 

(ii) consents to the entry of an order for relief against it in an involuntary case, 

(iii) consents to the appointment of a Custodian of it or for all or substantially all of its property, 

(iv) makes a general assignment for the benefit of its creditors, or 

  
 20 

 (v) generally is unable to pay its debts as the same become due; or 

(e) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 

(i) is for relief against the Company in an involuntary case, 

(ii) appoints a Custodian of the Company or for all or substantially all of its property, or 

(iii) orders the liquidation of the Company, and the order or decree remains unstayed and in effect for 60 days; or 

(f) any other Event of Default provided with respect to Securities of that Series, which is specified in a Board Resolution, a
supplemental indenture hereto or an Officer’s Certificate, in accordance with Section 2.2.18. 
 The term “Bankruptcy
Law” means title 11, U.S. Code or any similar Federal or State law for the relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator or similar official under any Bankruptcy Law. 

6.2 Acceleration of Maturity; Rescission and Annulment. If an Event of Default with respect to Securities of any Series at the time
outstanding occurs and is continuing (other than an Event of Default referred to in Section 6.1(d) or (e)) 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 (or, if any Securities of that Series are Discount Securities, such portion of the principal amount as may be specified in the terms of such Securities) of and accrued and unpaid interest, if any, on all of the
Securities of that Series to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or specified amount) and accrued and unpaid interest,
if any, shall become immediately due and payable. If an Event of Default specified in Section 6.1(d) or (e) shall occur, the principal amount (or specified amount) of and accrued and unpaid interest, if any, on all outstanding Securities
shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. 

At any time after such a declaration of acceleration with respect to 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 all Events of Default with respect to Securities of that Series, other than the non-payment of the principal and interest, if any, of Securities of that Series
which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 6.13. 

  
 21 

 No such rescission shall affect any subsequent Default or impair any right consequent
thereon. 
 6.3 Collection of Indebtedness and Suits for Enforcement by Trustee. The Company covenants that if 

(a) default is made in the payment of any interest on any Security when such interest becomes due and payable and such default
continues for a period of 30 days; or 
 (b) default is made in the payment of principal of any Security at the Maturity
thereof; or 
 (c) default is made in the deposit of any sinking fund payment, if any, when and as due by the terms of a
Security, 
 then, 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 interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and any overdue interest at the rate or rates prescribed therefor in such
Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 

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

 6.4 Trustee May File Proofs of Claim. In case of the pendency of any receivership,
insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for
the payment of overdue principal or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise, 

(a) to file and prove a claim for the whole amount of principal and interest owing and unpaid in respect of the Securities and
to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and
of the Holders allowed in such judicial proceeding, and 
 (b) to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same, 
 and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar
official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any
amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.7. 

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any
plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 

6.5 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. 

  
 23 

 6.6 Application of Money Collected. Any money or property 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 or property on account of principal 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 7.7; and 
 Second: To the payment of the amounts then due and unpaid for principal of 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 interest,
respectively; and 
 Third: To the Company. 

6.7 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 

(a) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the
Securities of that Series; 
 (b) the Holders of not less than 25% in principal amount of the outstanding Securities of that
Series shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; 

(c) such Holder or Holders have offered to the Trustee indemnity or security satisfactory to the Trustee against the costs,
expenses and liabilities which might be incurred by the Trustee in compliance with such request; 
 (d) the Trustee for 60
days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and 
 (e)
no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the outstanding Securities of that Series; 

it being understood, intended and expressly covenanted by the Holder of every Security with every other Holder and the Trustee 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 such Holders of the applicable Series. 

  
 24 

 6.8 Unconditional Right of Holders to Receive Principal and Interest. Notwithstanding
any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of and interest, if any, on such Security on the Maturity of such Security, including
the Stated Maturity expressed in such Security (or, in the case of redemption, on the redemption date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder. 

6.9 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. 

6.10 Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities in Section 2.8, 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, to the extent
permitted by law, prevent the concurrent assertion or employment of any other appropriate right or remedy. 
 6.11 Delay or Omission Not
Waiver. No delay or omission of the Trustee or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. 

6.12 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 

  
 25 

 (a) such direction shall not be in conflict with any rule of law or with
this Indenture, 
 (b) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such
direction, 
 (c) subject to the provisions of Section 6.1, the Trustee shall have the right to decline to follow any
such direction if the Trustee in good faith shall, by a Responsible Officer of the Trustee, determine that the proceeding so directed would involve the Trustee in personal liability, and 

(d) prior to taking any action as directed under this Section 6.12, the Trustee shall be entitled to indemnity
satisfactory to it against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction. 

6.13 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 in the payment of the principal of or interest on any Security of such Series
(provided, however, that the Holders of a majority in principal amount of the outstanding Securities of any Series may rescind an acceleration and its consequences, including any related payment default that resulted from such
acceleration). 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. 
 6.14 Undertaking for Costs. All parties to this Indenture agree, and each Holder of
any Security by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action
taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees,
against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Company, to any suit
instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the outstanding Securities of any Series, or to any suit instituted by any Holder for the enforcement
of the payment of the principal of or interest on any Security on or after the Maturity of such Security, including the Stated Maturity expressed in such Security (or, in the case of redemption, on the redemption date). 

  
 26 

 ARTICLE VII 

TRUSTEE 
 7.1 Duties of
Trustee. 
 (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by
this Indenture 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. 

(b) Except during the continuance of an Event of Default: 

(i) The Trustee need perform only those duties that are specifically set forth in this Indenture and no others. 

(ii) In the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, upon Officer’s Certificates or Opinions of Counsel furnished to the Trustee and conforming to the requirements of this Indenture; however, in the case of any such Officer’s Certificates
or Opinions of Counsel which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall examine such Officer’s Certificates and Opinions of Counsel to determine whether or not they conform to the form
requirements of this Indenture. 
 (c) The Trustee may not be relieved from liability for its own negligent action, its own negligent failure
to act or its own willful misconduct, except that: 
 (i) This paragraph does not limit the effect of paragraph (b) of
this Section. 
 (ii) The Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer,
unless it is proved that the Trustee was negligent in ascertaining the pertinent facts. 
 (iii) The Trustee shall not be
liable with respect to any action taken, suffered or omitted to be taken by it with respect to Securities of any Series in good faith in accordance with the direction of the Holders of a majority in principal amount of the outstanding Securities of
such 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
in accordance with Section 6.12. 

  
 27 

 (d) Every provision of this Indenture that in any way relates to the Trustee is subject to
paragraph (a), (b) and (c) of this Section. 
 (e) The Trustee may refuse to perform any duty or exercise any right or power unless it
receives indemnity satisfactory to it against the costs, expenses and liabilities which might be incurred by it in performing such duty or exercising such right or power. 

(f) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. Money
held in trust by the Trustee need not be segregated from other funds except to the extent required by law. 
 (g) No provision of this
Indenture shall require the Trustee to risk its own funds or otherwise incur any financial liability in the performance of any of its duties, or in the exercise of any of its rights or powers, if adequate indemnity against such risk is not assured
to the Trustee in its satisfaction. 
 (h) The Paying Agent, the Registrar and any authenticating agent shall be entitled to the protections
and immunities as are set forth in paragraphs (e), (f) and (g) of this Section and in Section 7.2, each with respect to the Trustee. 

7.2 Rights of Trustee. 

(a) The Trustee may rely on and shall be protected in acting or refraining from acting upon any document (whether in its original or facsimile
form) believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document. 

(b) Before the Trustee acts or refrains from acting, it may require an Officer’s Certificate or an Opinion of Counsel or both. The Trustee
shall not be liable for any action it takes or omits to take in good faith in reliance on such Officer’s Certificate or Opinion of Counsel. 

(c) The Trustee may act through agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care. No
Depositary shall be deemed an agent of the Trustee and the Trustee shall not be responsible for any act or omission by any Depositary. 
 (d)
The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers, provided that the Trustee’s conduct does not constitute willful misconduct or
negligence. 
 (e) The Trustee may consult with counsel and the 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 without willful misconduct or negligence, and in reliance thereon. 

  
 28 

 (f) 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 of Securities unless such Holders shall have offered to the Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities which might be
incurred by it in compliance with such request or direction. 
 (g) 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. 
 (h) The Trustee shall not be
deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust
Office of the Trustee, and such notice references the Securities generally or the Securities of a particular Series and this Indenture. 

(i) In no event shall the Trustee be liable to any person for special, punitive, indirect, consequential or incidental loss or damage of any
kind whatsoever (including but not limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage. 

(j) The permissive right of the Trustee to take the actions permitted by this Indenture shall not be construed as an obligation or duty to do
so. 
 7.3 Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of
Securities and may otherwise deal with the Company or an Affiliate of the Company with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. The Trustee is also subject to Sections 7.10 and 7.11. 

7.4 Trustee’s Disclaimer. The Trustee makes no representation as to the validity or adequacy of this Indenture or the Securities,
it shall not be accountable for the Company’s use of the proceeds from the Securities, and it shall not be responsible for any statement in the Securities other than its authentication. 

7.5 Notice of Defaults. If a Default or Event of Default occurs and is continuing with respect to the Securities of any Series and if it
is known to a Responsible Officer of the Trustee, the Trustee shall mail to each Securityholder of the Securities of that Series notice of a Default or Event of Default within 90 days after it occurs or, if

  
 29 

 
later, after a Responsible Officer of the Trustee has knowledge of such Default or Event of Default. Except in the case of a Default or Event of Default in payment of principal of or interest on
any Security of any Series, the Trustee may withhold the notice if and so long as its corporate trust committee or a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of Securityholders of
that Series. For all purposes of this Indenture, in the absence of actual knowledge, the Trustee shall not be deemed to have knowledge or notice of a Default or an Event of Default unless notified in writing by the Company or one or more
Securityholders; and “actual knowledge” (as used in the foregoing clause) of the Trustee shall mean actual knowledge of an officer in the Corporate Trust Office of the Trustee; provided that the Trustee is deemed to have actual
knowledge of the failure of the Company to pay any principal amount of, or interest on, the Securities directly to the Trustee when the same shall become due. 

7.6 Reports by Trustee to Holders. Within 60 days after May 12 in each year, the Trustee shall transmit by mail to all
Securityholders, as their names and addresses appear on the register kept by the Registrar, a brief report dated as of such May 12, in accordance with, and to the extent required under, TIA § 313. 

A copy of each report at the time of its mailing to Securityholders of any Series shall be filed with the SEC and each national securities
exchange on which the Securities of that Series are listed. The Company shall promptly notify the Trustee in writing when Securities of any Series are listed on any national securities exchange. 

7.7 Compensation and Indemnity. The Company shall pay to the Trustee from time to time compensation for its services as the Company and
the Trustee shall from time to time agree upon in writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable out
of pocket expenses incurred by it. Such expenses shall include the reasonable compensation and expenses of the Trustee’s agents and counsel. 

The Company shall indemnify each of the Trustee and any predecessor Trustee (including the cost of defending itself) against any cost, expense
or liability, including taxes (other than taxes based upon, measured by or determined by the income of the Trustee) incurred by it except as set forth in the next paragraph in the performance of its duties under this Indenture as Trustee or Agent.
The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder, unless and to the extent that the Company is
materially prejudiced thereby. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have one separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need
not pay for any settlement made without its consent, which consent will not be unreasonably withheld. This indemnification shall apply to officers, directors, employees, shareholders and agents of the Trustee. 

  
 30 

 The Company need not reimburse any expense or indemnify against any loss or liability
incurred by the Trustee or by any officer, director, employee, shareholder or agent of the Trustee through willful misconduct or negligence. 

To secure the Company’s payment obligations in this Section, the Trustee shall have a lien prior to the Securities of any Series on all
money or property held or collected by the Trustee, except that held in trust to pay principal of and interest on particular Securities of that Series. 

When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.1(d) or (e) occurs, the
expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. 
 The
provisions of this Section shall survive the termination of this Indenture. 
 7.8 Replacement of Trustee. A resignation or removal of
the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section. 

The Trustee may resign with respect to the Securities of one or more Series by so notifying the Company at least 30 days prior to the date of
the proposed resignation. The Holders of a majority in principal amount of the Securities of any Series may remove the Trustee with respect to that Series by so notifying the Trustee and the Company. The Company may remove the Trustee with respect
to Securities of one or more Series if: 
 (a) the Trustee fails to comply with Section 7.10; 

(b) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any
Bankruptcy Law; 
 (c) a Custodian or public officer takes charge of the Trustee or its property; or 

(d) the Trustee becomes incapable of acting. 

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a
successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Securities may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

  
 31 

 If a successor Trustee with respect to the Securities of any one or more Series does not
take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of at least a majority in principal amount of the Securities of the applicable Series may petition any court of competent
jurisdiction for the appointment of a successor Trustee. 
 A successor Trustee shall deliver a written acceptance of its appointment to the
retiring Trustee and to the Company. Immediately after that, the retiring Trustee shall transfer all property held by it as Trustee to the successor Trustee subject to the lien provided for in Section 7.7, the resignation or removal of the
retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee with respect to each Series of Securities for which it is acting as Trustee under this Indenture. A successor Trustee
shall mail a notice of its succession to each Securityholder of each such Series. Notwithstanding replacement of the Trustee pursuant to this Section 7.8, the Company’s obligations under Section 7.7 hereof shall continue for the
benefit of the retiring Trustee with respect to expenses and liabilities incurred by it for actions taken or omitted to be taken in accordance with its rights, powers and duties under this Indenture prior to such replacement. 

7.9 Successor Trustee by Merger, Etc. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all
of its corporate trust business to, another corporation or entity, the successor corporation or entity without any further act shall be the successor Trustee, subject to Section 7.10. 

7.10 Eligibility; Disqualification. This Indenture shall always have a Trustee who satisfies the requirements of TIA § 310(a)(1),
(2) and (5). The Trustee shall always have a combined capital and surplus of at least $25,000,000 as set forth in its most recent published annual report of condition. The Trustee shall comply with TIA § 310(b). 

7.11 Preferential Collection of Claims Against Company. The Trustee is subject to TIA § 311(a), excluding any creditor relationship
listed in TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated.

	 	(D)	 are deemed paid and discharged pursuant to Section 8.3, as applicable; 

and the Company, in the case of (1), (2) or (3) above, has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust an
amount sufficient for the purpose of paying and discharging the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, for principal and interest to the date of such deposit (in the case of Securities which
have become due and payable on or prior to the date of such deposit) or to the Stated Maturity or redemption date, as the case may be; 
 (b)
the Company has paid or caused to be paid all other sums payable hereunder by the Company; and 
 (c) the Company has delivered to the
Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with.

acting as its own Paying Agent) as the Trustee may determine, to the persons entitled thereto, of the principal and interest for whose payment such money has been deposited with or received by the Trustee or to make mandatory sinking fund payments
or analogous payments as contemplated by Sections 8.3 or 8.4. 
 (b) The Company shall pay and shall indemnify the Trustee against any tax,
fee or other charge imposed on or assessed against U.S. Government Obligations or Foreign Government Obligations deposited pursuant to Sections 8.3 or 8.4 or the interest and principal received in respect of such obligations other than any payable
by or on behalf of Holders. 
 (c) The Trustee shall deliver or pay to the Company from time to time upon Company Order any U.S. Government
Obligations or Foreign Government Obligations or money held by it as provided in Sections 8.3 or 8.4 which, in the opinion of a nationally recognized firm of independent certified public accountants or investment bank expressed in a written
certification thereof delivered to the Trustee, are then in excess of the amount thereof which then would have been required to be deposited for the purpose for which such U.S. Government Obligations or Foreign Government Obligations or money were
deposited or received. This provision shall not authorize the sale by the Trustee of any U.S. Government Obligations or Foreign Government Obligations held under this Indenture. 

8.3 Legal Defeasance of Securities of any Series. Unless this Section 8.3 is otherwise specified, pursuant to Section 2.2, to

(d) hereof, and the provisions of this Indenture, as it relates to such outstanding Securities of such Series, shall no longer be in effect (and the Trustee, at the expense of the Company, shall, upon receipt of a Company Order, execute
instruments acknowledging the same), except as to: 
 (a) the rights of Holders of Securities of such Series to receive, from
the trust funds described in subparagraph (d) hereof, (i) payment of the principal of and each installment of principal of and interest on the outstanding Securities of such Series on the Maturity of such principal or installment of principal

 35 

 
Securities of such Series will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit, defeasance and discharge 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 deposit, defeasance and discharge had not occurred;

Company with the intent of defeating, hindering, delaying or defrauding any other creditors of the Company; and 
 (i) the
Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for relating to the defeasance contemplated by this Section have been complied with. 

8.4 Covenant Defeasance. Unless this Section 8.4 is otherwise specified pursuant to Section 2.2 to be inapplicable to
Securities of any Series, the Company may omit to comply with respect to the Securities of any Series with any term, provision or condition set forth under Sections 4.2, 4.3, 4.4, 4.5, and 5.1 as well as any additional covenants specified in a
supplemental indenture for such Series of Securities or a Board Resolution or an Officer’s Certificate delivered pursuant to Section 2.2 (and the failure to comply with any such covenants shall not constitute a Default or Event of Default
with respect to such Series under Section 6.1) and the occurrence of any event specified in a supplemental indenture for such Series of Securities or a Board Resolution or an Officer’s Certificate delivered pursuant to Section 2.2.18
and designated as an Event of Default shall not constitute a Default or Event of Default hereunder, with respect to the Securities of such Series, provided that the following conditions shall have been satisfied: 

(a) With reference to this Section 8.4, the Company has deposited or caused to be irrevocably deposited (except as
provided in Section 8.2(c)) with the Trustee as trust funds in trust for the purpose of making the following payments specifically pledged as security for, and dedicated solely to, the benefit of the Holders of such Securities (i) in the
case of Securities of such Series denominated in Dollars, cash in Dollars and/or U.S. Government Obligations, or (ii) in the case of Securities of such Series denominated in a Foreign Currency (other than a composite currency), money and/or
Foreign Government Obligations, which through the payment of interest and principal in respect thereof in accordance with their terms, will provide (and without reinvestment and assuming no tax liability will be imposed on such Trustee), not later
than one day before the due date of any payment of money, an amount in cash, sufficient, in the opinion of a nationally recognized firm of independent certified public accountants or investment bank expressed in a written certification thereof
delivered to the Trustee, to pay and discharge each installment of principal of and interest, if any, on and any mandatory sinking fund payments in respect of the Securities of such Series on the dates such installments of interest or principal and
such sinking fund payments are due; 

  
 36 

 (b) Such deposit will 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; 

(c) No Default or Event of Default with respect to the Securities of such Series shall have occurred and be continuing on the
date of such deposit; 
 (d) 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 such deposit and covenant defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the
same times as would have been the case if such deposit and covenant defeasance had not occurred; 
 (e) The Company shall
have delivered to the Trustee an Officer’s Certificate stating the deposit was not made by the Company with the intent of defeating, hindering, delaying or defrauding any other creditors of the Company; and 

(f) The Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that
all conditions precedent herein provided for relating to the covenant defeasance contemplated by this Section have been complied with. 
 8.5
Repayment to Company. Subject to applicable abandoned property law, the Trustee and the Paying Agent shall pay to the Company upon request any money held by them for the payment of principal and interest that remains unclaimed for two years.
After that, Securityholders entitled to the money must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person. 

8.6 Reinstatement. If the Trustee or the Paying Agent is unable to apply any money deposited with respect to Securities of any Series in
accordance with Section 8.1 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the obligations of the Company under
this Indenture with respect to the Securities of such Series and under the Securities of such Series shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.1 until such time as the Trustee or the Paying Agent is
permitted to apply all such money in accordance with Section 8.1; provided, however, that if the Company has made any payment of principal of or interest on or any Additional Amounts with respect to 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 held by the Trustee or Paying Agent. 

  
 37 

 ARTICLE IX 

AMENDMENTS AND WAIVERS 
 9.1
Without Consent of Holders. The Company and the Trustee may amend or supplement this Indenture or the Securities of one or more Series without the consent of any Securityholder: 

(a) to cure any ambiguity, defect or inconsistency; 

(b) to comply with Article V; 

(c) to provide for uncertificated Securities in addition to or in place of certificated Securities; 

(d) to make any change that does not adversely affect the rights of any Securityholder; 

(e) to provide for the issuance of and establish the form and terms and conditions of Securities of any Series as permitted by
this Indenture; 
 (f) to evidence and provide for the acceptance of appointment hereunder by a successor Trustee with
respect to the Securities of one or more Series 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; or 

(g) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA.

 9.2 With Consent of Holders. The Company and the Trustee may enter into a supplemental indenture with the written consent of the
Holders of at least a majority in principal amount of the outstanding Securities of each Series affected by such supplemental indenture (including consents obtained in connection with a tender offer or exchange offer for the Securities of such
Series), for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of any supplemental indenture or of modifying in any manner the rights of the Securityholders of each such
Series. Except as provided in Section 6.13, the Holders of at least a majority in principal amount of the outstanding Securities of any Series by notice to the Trustee (including consents obtained in connection with a tender offer or exchange
offer for the Securities of such Series) may waive compliance by the Company with any provision of this Indenture or the Securities with respect to such Series. 

  
 38 

 It shall not be necessary for the consent of the Holders of Securities under this
Section 9.2 to approve the particular form of any proposed supplemental indenture or waiver, but it shall be sufficient if such consent approves the substance thereof. After a supplemental indenture or waiver under this section becomes
effective, the Company shall mail to the Holders of Securities affected thereby, a notice briefly describing the supplemental indenture or waiver. Any failure by the Company to mail or publish such notice, or any defect therein, shall not, however,
in any way impair or affect the validity of any such supplemental indenture or waiver. 
 9.3 Limitations. Without the consent of each
Securityholder affected, an amendment or waiver may not: 
 (a) reduce the principal amount of Securities whose Holders must
consent to an amendment, supplement or waiver; 
 (b) reduce the rate of or extend the time for payment of interest
(including default interest) on any Security; 
 (c) reduce the principal or change the Stated Maturity of any Security or
reduce the amount of, or postpone the date fixed for, the payment of any sinking fund or analogous obligation; 
 (d) reduce
the principal amount of Discount Securities payable upon acceleration of the maturity thereof; 
 (e) waive a Default or
Event of Default in the payment of the principal of or interest, if any, on any Security (except a rescission of acceleration of the Securities of any Series by the Holders of at least a majority in principal amount of the outstanding Securities of
such Series and a waiver of the payment default that resulted from such acceleration); 
 (f) make the principal of or
interest, if any, on any Security payable in any currency other than that stated in the Security; 
 (g) make any change in
Sections 6.8, 6.13 or 9.3 (this sentence); or 
 (h) waive a redemption payment with respect to any Security, provided
that such redemption is made at the Company’s option. 
 9.4 Compliance with Trust Indenture Act. Every amendment to this
Indenture or the Securities of one or more Series shall be set forth in a supplemental indenture hereto that complies with the TIA as then in effect. 

  
 39 

 9.5 Revocation and Effect of Consents. Until an amendment is set forth in a
supplemental indenture or a waiver becomes effective, a consent to it by a Holder of a Security is a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting
Holder’s Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the consent as to his Security or portion of a Security if the Trustee receives the notice of revocation
before the date of the supplemental indenture or the date the waiver becomes effective. 
 Any amendment or waiver once effective shall bind
every Securityholder of each Series affected by such amendment or waiver unless it is of the type described in any of clauses (a) through (h) of Section 9.3. In that case, the amendment or waiver shall bind each Holder of a Security who
has consented to it and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security. 

9.6 Notation on or Exchange of Securities. The Trustee may place an appropriate notation about an amendment or waiver on any Security of
any Series thereafter authenticated. The Company in exchange for Securities of that Series may issue and the Trustee shall authenticate upon request new Securities of that Series that reflect the amendment or waiver. 

9.7 Trustee Protected. 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 be entitled to receive, and (subject to Section 7.1) shall be fully protected in relying upon, an Officer’s Certificate or an Opinion of Counsel or
both complying with Section 10.4. The Trustee shall sign all supplemental indentures upon delivery of such an Officer’s Certificate or Opinion of Counsel or both, except that the Trustee need not sign any supplemental indenture that
adversely affects its rights.

Series. Any Agent may make reasonable rules and set reasonable requirements for its functions. 
 10.7 Legal Holidays. Unless
otherwise provided by Board Resolution, Officer’s Certificate or supplemental indenture hereto for a particular Series, a “Legal Holiday” is any day that is not a Business Day. If a payment date is a Legal Holiday at a place of
payment, payment may be made at that place on the next succeeding day that is not a Legal Holiday, and no interest shall accrue for the intervening period. 

  
 42 

 10.8 No Recourse Against Others. A director, officer, employee or stockholder (past
or present), as such, of the Company shall not have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each
Securityholder by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities. 

10.9 Counterparts. This Indenture may be executed in any number of counterparts and by the parties hereto in separate counterparts, each
of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. 

10.10 Governing Law. THIS INDENTURE AND THE SECURITIES, INCLUDING ANY CLAIM OR CONTROVERSY ARISING OUT OF OR RELATING TO THE INDENTURE

10.11 No Adverse Interpretation of Other Agreements. This Indenture may not be used to interpret another indenture, loan or debt
agreement of the Company or a Subsidiary of the Company. Any such indenture, loan or debt agreement may not be used to interpret this Indenture. 

10.12 Successors. All agreements of the Company in this Indenture and the Securities shall bind its successor. All agreements of the
Trustee in this Indenture shall bind its successor. 
 10.13 Severability. 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. 

10.14 Table of Contents, Headings, Etc. The Table of Contents, Cross Reference Table, and headings of the Articles and Sections of this
Indenture have been inserted for convenience of reference only, are not to be considered a part hereof, and shall in no way modify or restrict any of the terms or provisions hereof. 

10.15 Securities in a Foreign Currency. Unless otherwise specified in a Board Resolution, a supplemental indenture hereto or an
Officer’s Certificate delivered pursuant to Section 2.2 of this Indenture with respect to a particular Series of Securities, whenever for purposes of this Indenture any action may be taken by the Holders of a specified

  
 43 

 
percentage in aggregate principal amount of Securities of all Series or all Series affected by a particular action at the time outstanding and, at such time, there are outstanding Securities of
any Series which are denominated more than one currency, then the principal amount of Securities of such Series which shall be deemed to be outstanding for the purpose of taking such action shall be determined by converting any such other currency
into a currency that is designated upon issuance of any particular Series of Securities. Unless otherwise specified in a Board Resolution, a supplemental indenture hereto or an Officer’s Certificate delivered pursuant to Section 2.2 of
this Indenture with respect to a particular Series of Securities, such conversion shall be at the spot rate for the purchase of the designated currency as published in the The Financial Times in the “Currency Rates” section (of, if
The Financial Times is no longer published, or if such information is no longer available in The Financial Times, such source as may be selected in good faith by the Company) on any date of determination. The provisions of this
paragraph shall apply in determining the equivalent principal amount in respect of Securities of a Series denominated in currency other than Dollars in connection with any action taken by Holders of Securities pursuant to the terms of this
Indenture. 
 All decisions and determinations provided for in the preceding paragraph shall, in the absence of manifest error, to the
extent permitted by law, be conclusive for all purposes and irrevocably binding upon the Trustee and all Holders. 
 10.16 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
interest or other amount 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 day on which final unappealable judgment is entered, unless such day is not a New York Banking
Day, then 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 the
day on which final unappealable judgment is entered and (b) its obligations under this Indenture to make payments in the Required Currency (i) shall not be discharged or satisfied by any tender, 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 on which banking institutions are authorized or required by law, regulation or executive order to close. 

  
 44 

 10.17 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 best
efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances. 

ARTICLE XI 
 SINKING FUNDS 

11.1 Applicability of Article. The provisions of this Article shall be applicable to any sinking fund for the retirement of the
Securities of a Series if so provided by the terms of such Securities PURSUANT TO Section 2.2 and except as otherwise permitted or required by any form of Security of such Series issued pursuant to this Indenture. 

The minimum amount of any sinking fund payment provided for by the terms of the Securities of any Series is herein referred to as a
“mandatory sinking fund payment” and any other amount provided for by the terms of Securities of such Series is herein referred to as an “optional sinking fund payment.” If provided for by the terms of Securities of
any Series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 11.2. Each sinking fund payment shall be applied to the redemption of Securities of any Series as provided for by the terms of the
Securities of such Series. 
 11.2 Satisfaction of Sinking Fund Payments with Securities. The Company may, in satisfaction of all or
any part of any sinking fund payment with respect to the Securities of any Series to be made pursuant to the terms of such Securities (1) deliver outstanding Securities of such Series to which such sinking fund payment is applicable (other than
any of such Securities previously called for mandatory sinking fund redemption) and (2) apply as credit Securities of such Series to which such sinking fund payment is applicable and which have been repurchased by the Company or redeemed either
at the election of the Company pursuant to the terms of such Series of Securities (except pursuant to any mandatory sinking fund) or through the application of permitted optional sinking fund payments or other optional redemptions pursuant to the
terms of such Securities, provided that such Securities have not been previously so credited. Such Securities shall be received by the Trustee, together with an Officer’s Certificate with

  
 45 

 
respect thereto, not later than 15 days prior to the date on which the Trustee begins the process of selecting Securities for redemption, and shall be credited for such purpose by the Trustee at
the price specified in such Securities for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly. If as a result of the delivery or credit of Securities in lieu of cash payments
pursuant to this Section 11.2, the principal amount of Securities of such Series to be redeemed in order to exhaust the aforesaid cash payment shall be less than $100,000, the Trustee need not call Securities of such Series for redemption,
except upon receipt of a Company Order that such action be taken, and such cash payment shall be held by the Trustee or a Paying Agent and applied to the next succeeding sinking fund payment, provided, however, that the Trustee or such
Paying Agent shall from time to time upon receipt of a Company Order pay over and deliver to the Company any cash payment so being held by the Trustee or such Paying Agent upon delivery by the Company to the Trustee of Securities of that Series
purchased by the Company having an unpaid principal amount equal to the cash payment required to be released to the Company. 
 11.3
Redemption of Securities for Sinking Fund. Not less than 45 days (unless otherwise indicated in the Board Resolution, supplemental indenture hereto or Officer’s Certificate in respect of a particular Series of Securities) prior to each
sinking fund payment date for any Series of Securities, the Company will deliver to the Trustee an Officer’s Certificate specifying the amount of the next ensuing mandatory sinking fund payment for that Series pursuant to the terms of that
Series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting of Securities of that Series pursuant to Section 11.2, and the optional
amount, if any, to be added in cash to the next ensuing mandatory sinking fund payment, and the Company shall thereupon be obligated to pay the amount therein specified. Not less than 30 days (unless otherwise indicated in the Board Resolution,
Officer’s Certificate or supplemental indenture in respect of a particular Series of Securities) before 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 3.2 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 3.3. Such notice having been duly given, the redemption of such Securities
shall be made upon the terms and in the manner stated in Sections 3.4, 3.5 and 3.6.

Solicitation Agent and the Company fails to instruct the Bid Solicitation Agent to obtain bids when required; or (C) the Bid Solicitation Agent fails to solicit bids when required, then, in each case, the Trading Price per $1,000 principal
amount of Notes on such Trading Day will be deemed to be less than ninety eight percent (98%) of the product of the Last Reported Sale Price per share of Common Stock on such Trading Day and the Conversion Rate on such Trading Day.

 Article 2. THE NOTES 

Section 2.01. FORM, DATING AND DENOMINATIONS. 

The Notes and the Trustee’s certificate of authentication will be substantially in the form set forth in Exhibit A. The Notes will
bear the legends required by Section 2.09 and may bear notations, legends or endorsements required by law, stock exchange rule or usage or the Depositary. Each Note will be dated as of the date of its authentication. 

Except to the extent otherwise provided in a Company Order delivered to the Trustee in connection with the issuance and authentication
thereof, the Notes will be issued initially in the form of one or more Global Notes. Global Notes may be exchanged for Physical Notes, and Physical Notes may be exchanged for Global Notes, only as provided in Section 2.10.

 The Notes will be issuable only in registered form without interest coupons and only in Authorized Denominations. 

Each certificate representing a Note will bear a unique registration number that is not affixed to any other certificate representing another
outstanding Note. 
 The terms contained in the Notes constitute part of the Indenture, and, to the extent applicable, the Company and the
Trustee, by their execution and delivery of this Supplemental Indenture, agree to such terms and to be bound thereby; provided, however, that, to the extent that any provision of any Note conflicts with the provisions of the Indenture,
the provisions of the Indenture will control for purposes of the Indenture and such Note. 
 Section 2.02. EXECUTION,
AUTHENTICATION AND DELIVERY. 
 (A) Due Execution by the Company. At least one
(1) duly authorized Officer will sign the Notes on behalf of the Company by manual or facsimile signature. A Note’s validity will not be affected by the failure of any Officer whose signature is on any Note to hold, at the time such Note
is authenticated, the same or any other office at the Company. 
 (B) Authentication by the Trustee and Delivery. 

(i) No Note will be valid until it is authenticated by the Trustee. A Note will be deemed to be duly authenticated only when an
authorized signatory of the Trustee (or a duly appointed authenticating agent) manually signs the certificate of authentication of such Note. 

(ii) The Trustee will cause an authorized signatory of the Trustee (or a duly appointed authenticating agent) to manually sign
the certificate of authentication of a Note only if (1) the Company delivers such Note to the Trustee; (2) such Note is executed by the Company in accordance with Section 2.02(A); and (3) the Company delivers
a Company Order to the Trustee that (a) requests the Trustee to authenticate such Note; and (b) sets forth the name of the Holder of such Note and the date as of which such Note is to be authenticated. If such Company Order also requests
the Trustee to deliver such Note to any Holder or to the Depositary, then the Trustee will promptly deliver such Note in accordance with such Company Order. 

  
 - 13 - 

 (iii) The Trustee may appoint an authenticating agent acceptable to the
Company to authenticate Notes. A duly appointed authenticating agent may authenticate Notes whenever the Trustee may do so under the Indenture, and a Note authenticated as provided in the Indenture by such an agent will be deemed, for purposes of
the Indenture, to be authenticated by the Trustee. Each duly appointed authenticating agent will have the same rights to deal with the Company as the Trustee would have if it were performing the duties that the authentication agent was validly
appointed to undertake. 
 Section 2.03. INITIAL NOTES AND ADDITIONAL
NOTES. 
 (A) Initial Notes. On the Issue Date, there will be originally issued one hundred seventy five million
dollars ($175,000,000) aggregate principal amount of Notes, subject to the provisions of the Indenture (including Section 2.02). If the Underwriters exercise the Shoe Option, then there will be originally issued up to an
additional twenty six million two hundred fifty thousand dollars ($26,250,000) principal amount of Notes pursuant to such exercise, subject to the provisions of the Indenture (including Section 2.02). Notes issued pursuant
to this Section 2.03(A), and any Notes issued in exchange therefor or in substitution thereof, are referred to in the Indenture as the “Initial Notes.” 

(B) Additional Notes. The Company may, subject to the provisions of the Indenture (including Section 2.02),
originally issue additional Notes with the same terms as the initial Notes (except, to the extent applicable, with respect to the date as of which interest begins to accrue on such additional Notes and the first Interest Payment Date of such
additional Notes), which additional Notes will, subject to the foregoing, be considered to be part of the same series of, and rank equally and ratably with all other, Notes issued under the Indenture; provided, however, that if any
such additional Notes are not fungible with other Notes issued under the Indenture for federal income tax or federal securities laws purposes, then such additional Notes will be identified by a separate CUSIP number or by no CUSIP number. 

Section 2.04. METHOD OF PAYMENT. 

(A) Global Notes. The Company will pay, or cause the Paying Agent to pay, the principal (whether due upon maturity on the Maturity Date
or repurchase on a Fundamental Change Repurchase Date or otherwise) of, interest on, and any cash Conversion Consideration for, any Global Note to the Depositary by wire transfer of immediately available funds no later than the time the same is due
as provided in the Indenture. 
 (B) Physical Notes. The Company will pay, or cause the Paying Agent to pay, the principal (whether
due upon maturity on the Maturity Date or repurchase on a Fundamental Change Repurchase Date or otherwise) of, interest on, and any cash Conversion Consideration for, any Physical Note no later than the time the same is due as provided in the
Indenture as follows: (i) if the principal amount of such Physical Note is at least five million dollars ($5,000,000) (or such lower amount as the Company may choose in its sole and absolute discretion) and the Holder of such Physical Note
entitled to such payment has delivered to the 

  
 - 14 - 

 
Paying Agent or the Trustee, no later than the time set forth in the immediately following sentence, a written request that the Company make such payment by wire transfer to an account of such
Holder within the United States, by wire transfer of immediately available funds to such account; and (ii) in all other cases, by check mailed to the address of the Holder of such Physical Note entitled to such payment as set forth in the
Register. To be timely, such written request must be so delivered no later than the Close of Business on the following date: (x) with respect to the payment of any interest due on an Interest Payment Date, the immediately preceding Regular
Record Date; (y) with respect to any cash Conversion Consideration, the relevant Conversion Date; and (z) with respect to any other payment, the date that is fifteen (15) calendar days immediately before the date such payment is due.

 Section 2.05. ACCRUAL OF INTEREST; DEFAULTED AMOUNTS;
WHEN PAYMENT DATE IS NOT A BUSINESS DAY. 

(A) Accrual of Interest. Each Note will accrue interest at a rate per annum equal to 4.75% (the “Stated Interest”),
plus any Special Interest that may accrue pursuant to Section 7.03. Stated Interest on each Note will (i) accrue from, and including, the most recent date to which Stated Interest has been paid or duly provided for (or, if no
Stated Interest has theretofore been paid or duly provided for, the date set forth in the certificate representing such Note as the date from, and including, which Stated Interest will begin to accrue in such circumstance) to, but excluding, the
date of payment of such Stated Interest; and (ii) be, subject to Sections 4.02(D) and 5.02(D) (but without duplication of any payment of interest), payable semi-annually in arrears on each Interest Payment Date, beginning
on the first Interest Payment Date set forth in the certificate representing such Note, to the Holder of such Note as of the Close of Business on the immediately preceding Regular Record Date. Stated Interest, and, if applicable, Special Interest,
on the Notes will be computed on the basis of a 360-day year comprised of twelve 30-day months. 

(B) Defaulted Amounts. If the Company fails to pay any amount (a “Defaulted Amount”) payable on a Note on or before
the due date therefor as provided in the Indenture, then, regardless of whether such failure constitutes an Event of Default, (i) such Defaulted Amount will forthwith cease to be payable to the Holder of such Note otherwise entitled to such
payment; (ii) to the extent lawful, interest (“Default Interest”) will accrue on such Defaulted Amount at a rate per annum equal to the rate per annum at which Stated Interest accrues, from, and including, such due date to, but
excluding, the date of payment of such Defaulted Amount and Default Interest; (iii) such Defaulted Amount and Default Interest will be paid on a payment date selected by the Company to the Holder of such Note as of the Close of Business on a
special record date selected by the Company, provided that such special record date must be no more than fifteen (15), nor less than ten (10), calendar days before such payment date; and (iv) at least fifteen (15) calendar days
before such special record date, the Company will send notice to the Trustee and the Holders that states such special record date, such payment date and the amount of such Defaulted Amount and Default Interest to be paid on such payment date. 

(C) Delay of Payment when Payment Date is Not a Business Day. If the due date for a payment on a Note as provided in the Indenture is
not a Business Day, then, notwithstanding anything to the contrary in the Indenture or the Notes, such payment may be made on the immediately following Business Day and no interest will accrue on such payment as a result of the related delay. 

  
 - 15 - 

 Section 2.06. REGISTRAR, PAYING AGENT
AND CONVERSION AGENT. 
 (A) Generally. The Company will maintain (i) an office
or agency in the continental United States where Notes may be presented for registration of transfer or for exchange (the “Registrar”); (ii) an office or agency in the continental United States where Notes may be presented for
payment (the “Paying Agent”); and (iii) an office or agency in the continental United States where Notes may be presented for conversion (the “Conversion Agent”). If the Company fails to maintain a Registrar,
Paying Agent or Conversion Agent, then the Trustee will act as such. For the avoidance of doubt, the Company or any of its Subsidiaries may act as Registrar, Paying Agent or Conversion Agent. 

(B) Duties of the Registrar. The Registrar will keep a record (the “Register”) of the names and addresses of the
Holders, the Notes held by each Holder and the transfer, exchange, repurchase and conversion of Notes. Absent manifest error, the entries in the Register will be conclusive and the Company and the Trustee may treat each Person whose name is recorded
as a Holder in the Register as a Holder for all purposes. The Register will be in written form or in any form capable of being converted into written form reasonably promptly. 

(C) Co-Agents; Company’s Right to Appoint Successor Registrars, Paying Agents and Conversion
Agents. The Company may appoint one or more co-Registrars, co-Paying Agents and co-Conversion Agents, each of whom will be
deemed to be a Registrar, Paying Agent or Conversion Agent, as applicable, under the Indenture. Subject to Section 2.06(A), the Company may change any Registrar, Paying Agent or Conversion Agent (including appointing itself
or any of its Subsidiaries to act in such capacity) without notice to any Holder. The Company will notify the Trustee (and, upon request, any Holder) of the name and address of each Note Agent, if any, not a party to the Indenture and will enter
into an appropriate agency agreement with each such Note Agent, which agreement will implement the provisions of the Indenture that relate to such Note Agent. 

(D) Initial Appointments. The Company appoints the Trustee as the initial Paying Agent, the initial Registrar and the initial
Conversion Agent. For the avoidance of doubt, the Paying Agent, the Registrar, the Conversion Agent and any authenticating agent will be entitled to the protections and immunities of the Trustee as are set forth in Article VII of the Base Indenture.

 Section 2.07. PAYING AGENT AND CONVERSION AGENT TO
HOLD PROPERTY IN TRUST. 
 The Company will require each Paying Agent or Conversion Agent
that is not the Trustee to agree in writing that such Note Agent will (A) hold in trust for the benefit of Holders or the Trustee all money and other property held by such Note Agent for payment or delivery due on the Notes; and (B) notify
the Trustee of any default by the Company in making any such payment or delivery. The Company, at any time, may, and the Trustee, while any Default continues, may, require a Paying Agent or Conversion Agent to pay or deliver, as applicable, all
money and other property held by it to the Trustee, after which payment or delivery, as applicable, such Note Agent (if not the Company or any of its Subsidiaries) will have no further 

  
 - 16 - 

 
liability for such money or property. If the Company or any of its Subsidiaries acts as Paying Agent or Conversion Agent, then (A) it will segregate and hold in a separate trust fund for the
benefit of the Holders or the Trustee all money and other property held by it as Paying Agent or Conversion Agent; and (B) references in the Indenture or the Notes to the Paying Agent or Conversion Agent holding cash or other property, or to
the delivery of cash or other property to the Paying Agent or Conversion Agent, in each case for payment or delivery to any Holders or the Trustee or with respect to the Notes, will be deemed to refer to cash or other property so segregated and held
separately, or to the segregation and separate holding of such cash or other property, respectively. Upon the occurrence of any event pursuant to in clause (ix) or (x) of Section 7.01(A) with
respect to the Company (or with respect to any Subsidiary of the Company acting as Paying Agent or Conversion Agent), the Trustee will serve as the Paying Agent or Conversion Agent, as applicable, for the Notes. 

Section 2.08. HOLDER LISTS. 

If the Trustee is not the Registrar, the Company will furnish to the Trustee, no later than seven (7) Business Days before each Interest Payment Date, and
at such other times as the Trustee may request, a list, in such form and as of such date or time as the Trustee may reasonably require, of the names and addresses of the Holders. 

Section 2.09. LEGENDS. 

(A) Global Note Legend. Each Global Note will bear the Global Note Legend (or any similar legend, not inconsistent with the Indenture,
required by the Depositary for such Global Note). 
 (B) Other Legends. A Note may bear any other legend or text, not inconsistent
with the Indenture, as may be required by applicable law or by any securities exchange or automated quotation system on which such Note is traded or quoted. 

(C) Acknowledgement and Agreement by the Holders. A Holder’s acceptance of any Note bearing any legend required by this
Section 2.09 will constitute such Holder’s acknowledgement of, and agreement to comply with, the restrictions set forth in such legend. 

Section 2.10. TRANSFERS AND EXCHANGES; CERTAIN TRANSFER
RESTRICTIONS. 
 (A) Provisions Applicable to All Transfers and Exchanges. 

(i) Subject to this Section 2.10, Physical Notes and beneficial interests in Global Notes may be
transferred or exchanged from time to time and the Registrar will record each such transfer or exchange in the Register. 

(ii) Each Note issued upon transfer or exchange of any other Note (such other Note being referred to as the “old
Note” for purposes of this Section 2.10(A)(ii)) or portion thereof in accordance with the Indenture will be the valid obligation of the Company, evidencing the same indebtedness, and entitled to the same benefits under
the Indenture, as such old Note or portion thereof, as applicable. 

  
 - 17 - 

 (iii) The Company, the Trustee and the Note Agents will not impose any
service charge on any Holder for any transfer, exchange or conversion of Notes, but the Company, the Trustee, the Registrar and the Conversion Agent may require payment of a sum sufficient to cover any transfer tax or similar governmental charge
that may be imposed in connection with any transfer, exchange or conversion of Notes, other than exchanges pursuant to Section 2.11, 2.16 or 8.05 not involving any transfer. 

(iv) Notwithstanding anything to the contrary in the Indenture or the Notes, a Note may not be transferred or exchanged in part
unless the portion to be so transferred or exchanged is in an Authorized Denomination. 
 (v) The Trustee will have no
obligation or duty to monitor, determine or inquire as to compliance with any transfer restrictions imposed under the Indenture or applicable law with respect to any Note Security, other than to require the delivery of such certificates or other
documentation or evidence as expressly required by the Indenture and to examine the same to determine substantial compliance as to form with the requirements of the Indenture. 

(vi) Each Note issued upon transfer of, or in exchange for, another Note will bear each legend, if any, required by
Section 2.09. 
 (vii) Upon satisfaction of the requirements of the Indenture to effect a transfer
or exchange of any Note, the Company will cause such transfer or exchange to be effected as soon as reasonably practicable but in no event later than the second (2nd) Business Day after the date of such satisfaction. 

(B) Transfers and Exchanges of Global Notes. 

(i) Subject to the immediately following sentence, no Global Note may be transferred or exchanged in whole except (x) by
the Depositary to a nominee of the Depositary; (y) by a nominee of the Depositary to the Depositary or to another nominee of the Depositary; or (z) by the Depositary or any such nominee to a successor Depositary or a nominee of such
successor Depositary. No Global Note (or any portion thereof) may be transferred to, or exchanged for, a Physical Note; provided, however, that a Global Note will be exchanged, pursuant to customary procedures, for one or more Physical
Notes if: 
 (1) (x) the Depositary notifies the Company or the Trustee that the Depositary is unwilling or unable to
continue as depositary for such Global Note or (y) the Depositary ceases to be a “clearing agency” registered under Section 17A of the Exchange Act and, in each case, the Company fails to appoint a successor Depositary within
ninety (90) days of such notice or cessation; 
 (2) an Event of Default has occurred and is continuing and the Company,
the Trustee or the Registrar has received a written request from the Depositary, or from a holder of a beneficial interest in such Global Note, to exchange such Global Note or beneficial interest, as applicable, for one or more Physical Notes; or

  
 - 18 - 

 (3) the Company, in its sole discretion, permits the exchange of any
beneficial interest in such Global Note for one or more Physical Notes at the request of the owner of such beneficial interest. 

(ii) Upon satisfaction of the requirements of the Indenture to effect a transfer or exchange of any Global Note (or any portion
thereof): 
 (1) the Trustee will reflect any resulting decrease of the principal amount of such Global Note by notation on
the “Schedule of Exchanges of Interests in the Global Note” forming part of such Global Note (and, if such notation results in such Global Note having a principal amount of zero, the Company may (but is not required to) instruct the
Trustee to cancel such Global Note pursuant to Section 2.14); 
 (2) if required to effect such
transfer or exchange, then the Trustee will reflect any resulting increase of the principal amount of any other Global Note by notation on the “Schedule of Exchanges of Interests in the Global Note” forming part of such other Global Note;

 (3) if required to effect such transfer or exchange, then the Company will issue, execute and deliver, and the Trustee
will authenticate, in each case in accordance with Section 2.02, a new Global Note bearing each legend, if any, required by Section 2.09; and 

(4) if such Global Note (or such portion thereof), or any beneficial interest therein, is to be exchanged for one or more
Physical Notes, then the Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, one or more Physical Notes that (x) are in Authorized Denominations and
have an aggregate principal amount equal to the principal amount of such Global Note to be so exchanged; (y) are registered in such name(s) as the Depositary specifies (or as otherwise determined pursuant to customary procedures); and
(z) bear each legend, if any, required by Section 2.09. 
 (iii) Each transfer or exchange of
a beneficial interest in any Global Note will be made in accordance with the Depositary Procedures. 
 (C) Transfers and Exchanges of
Physical Notes. 
 (i) Subject to this Section 2.10, a Holder of a Physical Note may
(x) transfer such Physical Note (or any portion thereof in an Authorized Denomination) to one or more other Person(s); (y) exchange such Physical Note (or any portion thereof in an Authorized Denomination) for one or more other Physical Notes
in Authorized Denominations having an aggregate principal amount equal to the aggregate principal amount of the Physical Note (or portion thereof) to be so exchanged; and (z) if then permitted by the Depositary Procedures, transfer such
Physical Note (or any portion thereof in an Authorized Denomination) in exchange for a beneficial interest in one or more Global Notes; provided, however, that, to effect any such transfer or exchange, such Holder must surrender such
Physical Note to be transferred or exchanged to the office of the Registrar, together with any endorsements or transfer instruments reasonably required by the Company, the Trustee or the Registrar. 

  
 - 19 - 

 (ii) Upon the satisfaction of the requirements of the Indenture to effect a
transfer or exchange of any Physical Note (such Physical Note being referred to as the “old Physical Note” for purposes of this Section 2.10(C)(ii)) of a Holder (or any portion of such old Physical Note in an
Authorized Denomination): 
 (1) such old Physical Note will be promptly cancelled pursuant to
Section 2.14; 
 (2) if such old Physical Note is to be so transferred or exchanged only in part,
then the Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, one or more Physical Notes that (x) are in Authorized Denominations and have an
aggregate principal amount equal to the principal amount of such old Physical Note not to be so transferred or exchanged; (y) are registered in the name of such Holder; and (z) bear each legend, if any, required by
Section 2.09; 
 (3) in the case of a transfer: 

(a) to the Depositary or a nominee thereof that will hold its interest in such old Physical Note (or such portion thereof) to
be so transferred in the form of one or more Global Notes, the Trustee will reflect an increase of the principal amount of one or more existing Global Notes by notation on the “Schedule of Exchanges of Interests in the Global Note” forming
part of such Global Note(s), which increase(s) are in Authorized Denominations and aggregate to the principal amount to be so transferred, and which Global Note(s) bear each legend, if any, required by Section 2.09;
provided, however, that if such transfer cannot be so effected by notation on one or more existing Global Notes (whether because no Global Notes bearing each legend, if any, required by Section 2.09 then
exist, because any such increase will result in any Global Note having an aggregate principal amount exceeding the maximum aggregate principal amount permitted by the Depositary or otherwise), then the Company will issue, execute and deliver, and
the Trustee will authenticate, in each case in accordance with Section 2.02, one or more Global Notes that (x) are in Authorized Denominations and have an aggregate principal amount equal to the principal amount to be
so transferred; and (y) bear each legend, if any, required by Section 2.09; and 
 (b) to a
transferee that will hold its interest in such old Physical Note (or such portion thereof) to be so transferred in the form of one or more Physical Notes, the Company will issue, execute and deliver, and the Trustee will authenticate, in each case
in accordance with Section 2.02, one or more Physical Notes that (x) are in Authorized Denominations and have an aggregate principal amount equal to the principal amount to be so transferred; (y) are registered in
the name of such transferee; and (z) bear each legend, if any, required by Section 2.09; and 

  
 - 20 - 

 (4) in the case of an exchange, the Company will issue, execute and deliver,
and the Trustee will authenticate, in each case in accordance with Section 2.02, one or more Physical Notes that (x) are in Authorized Denominations and have an aggregate principal amount equal to the principal amount
to be so exchanged; (y) are registered in the name of the Person to whom such old Physical Note was registered; and (z) bear each legend, if any, required by Section 2.09. 

(D) Transfers of Notes Subject to Repurchase or Conversion. Notwithstanding anything to the contrary in the Indenture or the Notes, the
Company, the Trustee and the Registrar will not be required to register the transfer of or exchange any Note that (i) has been surrendered for conversion, except to the extent that any portion of such Note is not subject to conversion; or
(ii) is subject to a Fundamental Change Repurchase Notice validly delivered, and not withdrawn, pursuant to Section 4.02(F), except to the extent that any portion of such Note is not subject to such notice or the
Company fails to pay the applicable Fundamental Change Repurchase Price when due. 
 Section 2.11. EXCHANGE AND
CANCELLATION OF NOTES TO BE CONVERTED OR REPURCHASED. 

(A) Partial Conversions and Repurchases of Physical Notes. If only a portion of a Physical Note of a Holder is to be converted
pursuant to Article 5 or repurchased pursuant to a Repurchase Upon Fundamental Change, then, as soon as reasonably practicable after such Physical Note is surrendered for such conversion or repurchase, the Company will cause such Physical
Note to be exchanged, pursuant and subject to Section 2.10(C), for (i) one or more Physical Notes that are in Authorized Denominations and have an aggregate principal amount equal to the principal amount of such
Physical Note that is not to be so converted or repurchased, as applicable, and deliver such Physical Note(s) to such Holder; and (ii) a Physical Note having a principal amount equal to the principal amount to be so converted or repurchased, as
applicable, which Physical Note will be converted or repurchased, as applicable, pursuant to the terms of the Indenture; provided, however, that the Physical Note referred to in this clause (ii) need not be issued at any
time after which such principal amount subject to such conversion or repurchase, as applicable, is deemed to cease to be outstanding pursuant to Section 2.17. 

(B) Cancellation of Converted and Repurchased Notes. 

(i) Physical Notes. If a Physical Note (or any portion thereof that has not theretofore been exchanged pursuant to
Section 2.11(A)) of a Holder is to be converted pursuant to Article 5 or repurchased pursuant to a Repurchase Upon Fundamental Change, then, promptly after the later of the time such Physical Note (or such portion)
is deemed to cease to be outstanding pursuant to Section 2.17 and the time such Physical Note is surrendered for such conversion or repurchase, as applicable, (1) such Physical Note will be cancelled pursuant to
Section 2.14; and (2) in the case of a partial 

  
 - 21 - 

 
conversion or repurchase, the Company will issue, execute and deliver to such Holder, and the Trustee will authenticate, in each case in accordance with Section 2.02,
one or more Physical Notes that (x) are in Authorized Denominations and have an aggregate principal amount equal to the principal amount of such Physical Note that is not to be so converted or repurchased; (y) are registered in the name of
such Holder; and (z) bear each legend, if any, required by Section 2.09. 
 (ii) Global
Notes. If a Global Note (or any portion thereof) is to be converted pursuant to Article 5 or repurchased pursuant to a Repurchase Upon Fundamental Change, then, promptly after the time such Note (or such portion) is deemed to cease to be
outstanding pursuant to Section 2.17, the Trustee will reflect a decrease of the principal amount of such Global Note in an amount equal to the principal amount of such Global Note to be so converted or repurchased, as
applicable, by notation on the “Schedule of Exchanges of Interests in the Global Note” forming part of such Global Note (and, if the principal amount of such Global Note is zero following such notation, cancel such Global Note pursuant to
Section 2.14). 
 Section 2.12. REPLACEMENT NOTES. 

If a Holder of any Note claims that such Note has been mutilated, lost, destroyed or wrongfully taken, then the Company will issue, execute and
deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, a replacement Note upon surrender to the Trustee of such mutilated Note, or upon delivery to the Trustee of evidence of such loss,
destruction or wrongful taking reasonably satisfactory to the Trustee and the Company. In the case of a lost, destroyed or wrongfully taken Note, the Company and the Trustee may require the Holder thereof to provide such security or indemnity that
is reasonably satisfactory to the Company and the Trustee to protect the Company and the Trustee from any loss that any of them may suffer if such Note is replaced. 

Every replacement Note issued pursuant to this Section 2.12 will be an additional obligation of the Company and will
be entitled to all of the benefits of the Indenture equally and ratably with all other Notes issued under the Indenture. 
 Section 2.13.
REGISTERED HOLDERS; CERTAIN RIGHTS WITH RESPECT TO GLOBAL NOTES. 

Only the Holder of a Note will have rights under the Indenture as the owner of such Note. Without limiting the generality of the foregoing,
Depositary Participants will have no rights as such under the Indenture with respect to any Global Note held on their behalf by the Depositary or its nominee, or by the Trustee as its custodian, and the Company, the Trustee and the Note Agents, and
their respective agents, may treat the Depositary as the absolute owner of such Global Note for all purposes whatsoever; provided, however, that (A) the Holder of any Global Note may grant proxies and otherwise authorize any
Person, including Depositary Participants and Persons that hold interests in Notes through Depositary Participants, to take any action that such Holder is entitled to take with respect to such Global Note under the Indenture or the Notes; and
(B) the Company and the Trustee, and their respective agents, may give effect to any written certification, proxy or other authorization furnished by the Depositary. 

  
 - 22 - 

 Section 2.14. CANCELLATION. 

Without limiting the generality of Section 3.06, the Company may at any time deliver Notes to the Trustee for
cancellation. The Registrar, the Paying Agent and the Conversion Agent will forward to the Trustee each Note duly surrendered to them for transfer, exchange, payment or conversion. The Trustee will promptly cancel all Notes so surrendered to it in
accordance with its customary procedures. Without limiting the generality of Section 2.03(B), the Company may not originally issue new Notes to replace Notes that it has paid or that have been cancelled upon transfer,
exchange, payment or conversion. 
 Section 2.15. NOTES HELD BY THE
COMPANY OR ITS AFFILIATES. 
 Without limiting the generality of Sections
3.06 and 2.17, in determining whether the Holders of the required aggregate principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company or any of its Affiliates will be deemed not to be
outstanding; provided, however, that, for purposes of determining whether the Trustee is protected in relying on any such direction, waiver or consent, only Notes that the Trustee knows are so owned will be so disregarded. 

Section 2.16. TEMPORARY NOTES. 

Until definitive Notes are ready for delivery, the Company may issue, execute and deliver, and the Trustee will authenticate, in each case in
accordance with Section 2.02, temporary Notes. Temporary Notes will be substantially in the form of definitive Notes but may have variations that the Company considers appropriate for temporary Notes. The Company will
promptly prepare, issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, definitive Notes in exchange for temporary Notes. Until so exchanged, each temporary Note will
in all respects be entitled to the same benefits under the Indenture as definitive Notes. 
 Section 2.17. OUTSTANDING
NOTES. 
 (A) Generally. The Notes that are outstanding at any time will be deemed to be those Notes that, at such
time, have been duly executed and authenticated, excluding those Notes (or portions thereof) that have theretofore been (i) cancelled by the Trustee or delivered to the Trustee for cancellation in accordance with
Section 2.14; (ii) assigned a principal amount of zero by notation on the “Schedule of Exchanges of Interests in the Global Note” forming part of any a Global Note representing such Note; (iii) paid in full
(including upon conversion) in accordance with the Indenture; or (iv) deemed to cease to be outstanding to the extent provided in, and subject to, clause (B), (C) or (D) of this Section 2.17.

 (B) Replaced Notes. If a Note is replaced pursuant to Section 2.12, then such Note will cease to be
outstanding at the time of its replacement, unless the Trustee and the Company receive proof reasonably satisfactory to them that such Note is held by a “bona fide purchaser” under applicable law. 

  
 - 23 - 

 (C) Maturing Notes and Notes Subject to Repurchase. If, on a Fundamental Change
Repurchase Date or the Maturity Date, the Paying Agent holds money sufficient to pay the aggregate Fundamental Change Repurchase Price or principal amount, respectively, together, in each case, with the aggregate interest, in each case due on such
date, then (unless there occurs a Default in the payment of any such amount) (i) the Notes (or portions thereof) to be repurchased, or that mature, on such date will be deemed, as of such date, to cease to be outstanding, except to the extent
provided in Sections 4.02(D) or 5.02(D); and (ii) the rights of the Holders of such Notes (or such portions thereof), as such, will terminate with respect to such Notes (or such portions thereof), other than the right to receive
the Fundamental Change Repurchase Price or principal amount, as applicable, of, and accrued and unpaid interest on, such Notes (or such portions thereof), in each case as provided in the Indenture. 

(D) Notes to Be Converted. At the Close of Business on the Conversion Date for any Note (or any portion thereof) to be converted, such
Note (or such portion) will (unless there occurs a Default in the delivery of the Conversion Consideration or interest due, pursuant to Section 5.03(B) or Section 5.02(D), upon such conversion) be
deemed to cease to be outstanding, except to the extent provided in Section 5.02(D). 
 (E) Cessation of
Accrual of Interest. Except as provided in Sections 4.02(D) or 5.02(D), interest will cease to accrue on each Note from, and including, the date that such Note is deemed, pursuant to this Section 2.17, to
cease to be outstanding, unless there occurs a default in the payment or delivery of any cash or other property due on such Note. 
 Section 2.18.
REPURCHASES BY THE COMPANY. 
 Without limiting the generality of
Sections 2.14 and 3.06, the Company may, from time to time, repurchase Notes in open market purchases or in negotiated transactions without delivering prior notice to Holders. 

Section 2.19. CUSIP AND ISIN NUMBERS. 

The Company may use one or more CUSIP or ISIN numbers to identify any of the Notes, and, if so, the Company and the Trustee will use such CUSIP
or ISIN number(s) in notices to Holders; provided, however, that (i) the Trustee makes no representation as to the correctness or accuracy of any such CUSIP or ISIN number; and (ii) the effectiveness of any such notice will
not be affected by any defect in, or omission of, any such CUSIP or ISIN number. The Company will promptly notify the Trustee of any change in the CUSIP or ISIN number(s) identifying any Notes. 

Article 3. COVENANTS 

Section 3.01. PAYMENT ON NOTES. 

(A) Generally. The Company will pay or cause to be paid all the principal of, the Fundamental Change Repurchase Price for, interest on,
and other amounts due with respect to, the Notes on the dates and in the manner set forth in the Indenture.

 (B) Deposit of Funds. Before 10:00 A.M., New York City time, on each Fundamental
Change Repurchase Date or Interest Payment Date, and on the Maturity Date or any other date on which any cash amount is due on the Notes, the Company will deposit, or will cause there to be deposited, with the Paying Agent cash, in funds immediately
available on such date, sufficient to pay the cash amount due on the applicable Notes on such date. The Paying Agent will return to the Company, as soon as practicable, any money not required for such purpose. 

Section 3.02. EXCHANGE ACT REPORTS. 

(A) Generally. The Company will send to the Trustee copies of all reports that the Company is required to file with the SEC pursuant to
Section 13(a) or 15(d) of the Exchange Act within fifteen (15) calendar days after the date that the Company is required to file the same (after giving effect to all applicable grace periods under the Exchange Act); provided,
however, that the Company need not send to the Trustee any material for which the Company has received, or is seeking in good faith and has not been denied, confidential treatment by the SEC. Any report that the Company files with the SEC
through the EDGAR system (or any successor thereto) will be deemed to be sent to the Trustee at the time such report is so filed via the EDGAR system (or such successor). Upon the request of any Holder, the Trustee will provide to such Holder a copy
of any report that the Company has sent the Trustee pursuant to this Section 3.02(A), other than a report that is deemed to be sent to the Trustee pursuant to the preceding sentence. The Company will also comply with its
other obligations under Section 314(a)(1) of the Trust Indenture Act. 
 (B) Trustee’s Disclaimer. The Trustee need not
determine whether the Company has filed any material via the EDGAR system (or such successor). The sending or filing of reports pursuant to Section 3.02(A) will not be deemed to constitute constructive notice to the Trustee
of any information contained, or determinable from information contained, therein, including the Company’s compliance with any of its covenants under the Indenture. 

Section 3.03. COMPLIANCE AND DEFAULT CERTIFICATES. 

(A) Annual Compliance Certificate. Within one hundred twenty (120) days after December 31, 2020 and each fiscal year of the
Company ending thereafter, the Company will deliver an Officer’s Certificate to the Trustee stating (i) that the signatory thereto has supervised a review of the activities of the Company and its Subsidiaries during such fiscal year with a
view towards determining whether any Default or Event of Default has occurred; and (ii) whether, to such signatory’s knowledge, a Default or Event of Default has occurred or is continuing (and, if so, describing all such Defaults or Events
of Default and what action the Company is taking or proposes to take with respect thereto). 
 (B) Default Certificate. If a Default
or Event of Default occurs, then the Company will promptly deliver an Officer’s Certificate to the Trustee describing the same and what action the Company is taking or proposes to take with respect thereto. 

Section 3.04. STAY, EXTENSION AND USURY LAWS. 

To the extent that it may lawfully do so, the Company (A) agrees that it will not at any time insist upon, plead, or in any manner
whatsoever claim or take the benefit or advantage of, any stay, extension or usury law (wherever or whenever enacted or in force) that may affect the covenants or the performance of the Indenture; and (B) expressly waives all benefits or
advantages of any such law and agrees that it will not, by resort to any such law, hinder, delay or impede the execution of any power granted to the Trustee by the Indenture, but will suffer and permit the execution of every such power as though no
such law has been enacted. 

  
 - 25 - 

 Section 3.05. CORPORATE EXISTENCE. 

Subject to Article 6, the Company will cause to preserve and keep in full force and effect: 

(A) its corporate existence in accordance with the organizational documents of the Company; and 

(B) the material rights (charter and statutory), licenses and franchises of the Company and its Subsidiaries; 

provided, however, that the Company need not preserve or keep in full force and effect any such license or franchise if the Board of Directors
determines that (x) the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries, taken as a whole; and (y) the loss thereof is not, individually or in the aggregate, materially adverse
to the Holders. 
 Section 3.06. RESTRICTION ON ACQUISITION OF NOTES
BY THE COMPANY AND ITS AFFILIATES. 
 The
Company will promptly deliver to the Trustee for cancellation all Notes that the Company or any of its Subsidiaries have purchased or otherwise acquired. The Company will use commercially reasonable efforts to prevent any of its Affiliates from
acquiring any Note (or any beneficial interest therein). 
 Section 3.07. FURTHER INSTRUMENTS AND
ACTS. 
 At the Trustee’s request, the Company will execute and deliver such further instruments and do such further
acts as may be reasonably necessary or proper to more effectively carry out the purposes of the Indenture. 
 Article 4. REPURCHASE

 Section 4.01. NO SINKING FUND. 

No sinking fund is required to be provided for the Notes. 

Section 4.02. RIGHT OF HOLDERS TO REQUIRE THE
COMPANY TO REPURCHASE NOTES UPON A FUNDAMENTAL CHANGE. 

(A) Right of Holders to Require the Company to Repurchase Notes Upon a Fundamental Change. Subject to the other terms of this
Section 4.02, if a Fundamental Change occurs, then each Holder will have the right (the “Fundamental Change Repurchase Right”) to require the Company to repurchase such Holder’s Notes (or any portion
thereof in an Authorized Denomination) on the Fundamental Change Repurchase Date for such Fundamental Change for a cash purchase price equal to the Fundamental Change Repurchase Price. 

  
 - 26 - 

 (B) Repurchase Prohibited in Certain Circumstances. If the principal amount of the
Notes has been accelerated and such acceleration has not been rescinded on or before the Fundamental Change Repurchase Date for a Repurchase Upon Fundamental Change (including as a result of the payment of the related Fundamental Change Repurchase
Price, and any related interest pursuant to the proviso to Section 4.02(D), on such Fundamental Change Repurchase Date), then (i) the Company may not repurchase any Notes pursuant to this
Section 4.02; and (ii) the Company will cause any Notes theretofore surrendered for such Repurchase Upon Fundamental Change to be returned to the Holders thereof (or, if applicable with respect to Global Notes, cancel
any instructions for book-entry transfer to the Company, the Trustee or the Paying Agent of the applicable beneficial interest in such Notes in accordance with the Depositary Procedures). 

(C) Fundamental Change Repurchase Date. The Fundamental Change Repurchase Date for any Fundamental Change will be a Business Day of the
Company’s choosing that is no more than thirty five (35), nor less than twenty (20), Business Days after the date the Company sends the related Fundamental Change Notice pursuant to Section 4.02(E). 

(D) Fundamental Change Repurchase Price. The Fundamental Change Repurchase Price for any Note to be repurchased upon a Repurchase Upon
Fundamental Change following a Fundamental Change is an amount in cash equal to the principal amount of such Note plus accrued and unpaid interest on such Note to, but excluding, the Fundamental Change Repurchase Date for such Fundamental Change;
provided, however, that if such Fundamental Change Repurchase Date is after a Regular Record Date and on or before the next Interest Payment Date, then (i) the Holder of such Note at the Close of Business on such Regular Record
Date will be entitled, notwithstanding such Repurchase Upon Fundamental Change, to receive, on or, at the Company’s election, before such Interest Payment Date, the unpaid interest that would have accrued on such Note to, but excluding, such
Interest Payment Date (assuming, solely for these purposes, that such Note remained outstanding through such Interest Payment Date, if such Fundamental Change Repurchase Date is before such Interest Payment Date); and (ii) the Fundamental
Change Repurchase Price will not include accrued and unpaid interest on such Note to, but excluding, such Fundamental Change Repurchase Date. For the avoidance of doubt, if an Interest Payment Date is not a Business Day within the meaning of
Section 2.05(C) and such Fundamental Change Repurchase Date occurs on the Business Day immediately after such Interest Payment Date, then (x) accrued and unpaid interest on Notes to, but excluding, such Interest
Payment Date will be paid, in accordance with Section 2.05(C), on the next Business Day to Holders as of the Close of Business on the immediately preceding Regular Record Date; and (y) the Fundamental Change Repurchase
Price will include interest on Notes to be repurchased from, and including, such Interest Payment Date. 
 (E) Fundamental Change
Notice. On or before the twentieth (20th) calendar day after the occurrence of a Fundamental Change, the Company will send to each Holder, the Trustee and the Paying Agent a notice of such Fundamental Change (a “Fundamental Change
Notice”). Substantially contemporaneously, the Company will issue a press release through such national newswire service as the Company then uses (or publish the same through such other widely disseminated public medium as the Company then
uses, including its website) containing the information set forth in the Fundamental Change Notice. 

  
 - 27 - 

 Such Fundamental Change Notice must state: 

(i) briefly, the events causing such Fundamental Change; 

(ii) the effective date of such Fundamental Change; 

(iii) the procedures that a Holder must follow to require the Company to repurchase its Notes pursuant to this
Section 4.02, including the deadline for exercising the Fundamental Change Repurchase Right and the procedures for submitting and withdrawing a Fundamental Change Repurchase Notice; 

(iv) the Fundamental Change Repurchase Date for such Fundamental Change; 

(v) the Fundamental Change Repurchase Price per $1,000 principal amount of Notes for such Fundamental Change (and, if such
Fundamental Change Repurchase Date is after a Regular Record Date and on or before the next Interest Payment Date, the amount, manner and timing of the interest payment payable pursuant to the proviso to Section 4.02(D));

 (vi) the name and address of the Paying Agent and the Conversion Agent; 

(vii) the Conversion Rate in effect on the date of such Fundamental Change Notice and a description and quantification of any
adjustments to the Conversion Rate that may result from such Fundamental Change (including pursuant to Section 5.07); 

(viii) that Notes for which a Fundamental Change Repurchase Notice has been duly tendered and not duly withdrawn must be
delivered to the Paying Agent for the Holder thereof to be entitled to receive the Fundamental Change Repurchase Price; 

(ix) that Notes (or any portion thereof) that are subject to a Fundamental Change Repurchase Notice that has been duly tendered
may be converted only if such Fundamental Change Repurchase Notice is withdrawn in accordance with the Indenture; and 
 (x)
the CUSIP and ISIN numbers, if any, of the Notes. 
 Neither the failure to deliver a Fundamental Change Notice nor any defect in a
Fundamental Change Notice will limit the Fundamental Change Repurchase Right of any Holder or otherwise affect the validity of any proceedings relating to any Repurchase Upon Fundamental Change. 

  
 - 28 - 

 (F) Procedures to Exercise the Fundamental Change Repurchase Right. 

(i) Delivery of Fundamental Change Repurchase Notice and Notes to Be Repurchased. To exercise its Fundamental Change
Repurchase Right for a Note following a Fundamental Change, the Holder thereof must deliver to the Paying Agent: 
 (1)
before the Close of Business on the Business Day immediately before the related Fundamental Change Repurchase Date (or such later time as may be required by law), a duly completed, written Fundamental Change Repurchase Notice with respect to such
Note; and 
 (2) such Note, duly endorsed for transfer (if such Note is a Physical Note) or by book-entry transfer (if such
Note is a Global Note). 
 The Paying Agent will promptly deliver to the Company a copy of each Fundamental Change Repurchase Notice that it
receives. 
 (ii) Contents of Fundamental Change Repurchase Notices. Each Fundamental Change Repurchase Notice with
respect to a Note must state: 
 (1) if such Note is a Physical Note, the certificate number of such Note; 

(2) the principal amount of such Note to be repurchased, which must be an Authorized Denomination; and 

(3) that such Holder is exercising its Fundamental Change Repurchase Right with respect to such principal amount of such Note;

 provided, however, that if such Note is a Global Note, then such Fundamental Change Repurchase Notice must comply with the
Depositary Procedures (and any such Fundamental Change Repurchase Notice delivered in compliance with the Depositary Procedures will be deemed to satisfy the requirements of this Section 4.02(F)). 

(iii) Withdrawal of Fundamental Change Repurchase Notice. A Holder that has delivered a Fundamental Change Repurchase
Notice with respect to a Note may withdraw such Fundamental Change Repurchase Notice by delivering a written notice of withdrawal to the Paying Agent at any time before the Close of Business on the Business Day immediately before the related
Fundamental Change Repurchase Date. Such withdrawal notice must state: 
 (1) if such Note is a Physical Note, the
certificate number of such Note; 
 (2) the principal amount of such Note to be withdrawn, which must be an Authorized
Denomination; and 
 (3) the principal amount of such Note, if any, that remains subject to such Fundamental Change
Repurchase Notice, which must be an Authorized Denomination; 

  
 - 29 - 

 provided, however, that if such Note is a Global Note, then such withdrawal
notice must comply with the Depositary Procedures (and any such withdrawal notice delivered in compliance with the Depositary Procedures will be deemed to satisfy the requirements of this Section 4.02(F)). 

Upon receipt of any such withdrawal notice with respect to a Note (or any portion thereof), the Paying Agent will (x) promptly deliver a
copy of such withdrawal notice to the Company; and (y) if such Note is surrendered to the Paying Agent, cause such Note (or such portion thereof in accordance with Section 2.11, treating such Note as having been then
surrendered for partial repurchase in the amount set forth in such withdrawal notice as remaining subject to repurchase) to be returned to the Holder thereof (or, if applicable with respect to any Global Note, cancel any instructions for book-entry
transfer to the Company, the Trustee or the Paying Agent of the applicable beneficial interest in such Note in accordance with the Depositary Procedures). 

(G) Payment of the Fundamental Change Repurchase Price. Without limiting the Company’s obligation to deposit the Fundamental
Change Repurchase Price within the time proscribed by Section 3.01(B), the Company will cause the Fundamental Change Repurchase Price for a Note (or portion thereof) to be repurchased pursuant to a Repurchase Upon
Fundamental Change to be paid to the Holder thereof on or before the later of (i) the applicable Fundamental Change Repurchase Date; and (ii) the date (x) such Note is delivered to the Paying Agent (in the case of a Physical Note) or
(y) the Depositary Procedures relating to the repurchase, and the delivery to the Paying Agent, of such Holder’s beneficial interest in such Note to be repurchased are complied with (in the case of a Global Note). For the avoidance of
doubt, interest payable pursuant to the proviso to Section 4.02(D) on any Note to be repurchased pursuant to a Repurchase Upon Fundamental Change must be paid pursuant to such proviso regardless of whether such Note is
delivered or such Depositary Procedures are complied with pursuant to the first sentence of this Section 4.02(G). 

(H) Compliance with Applicable Securities Laws. To the extent applicable, the Company will comply with all federal and state securities
laws in connection with a Repurchase Upon Fundamental Change (including complying with Rules 13e-4 and 14e-1 under the Exchange Act and filing any required Schedule TO,
to the extent applicable) so as to permit effecting such Repurchase Upon Fundamental Change in the manner set forth in the Indenture. 
 (I)
Repurchase in Part. Subject to the terms of this Section 4.02, Notes may be repurchased pursuant to a Repurchase Upon Fundamental Change in part, but only in Authorized Denominations. Provisions of this
Section 4.02 applying to the repurchase of a Note in whole will equally apply to the repurchase of a permitted portion of a Note. 

Section 4.03. NO RIGHT OF REDEMPTION BY THE
COMPANY. 
 The Company does not have the right to redeem the Notes at its election.

Conversion Consideration. 
 (B) Conversions in Part. Subject to the terms of the Indenture, Notes may be converted in part, but only

(C) When Notes May Be Converted. 

(i) Generally. Subject to Section 5.01(C)(ii), a Note may be converted only in the following
circumstances: 
 (1) Conversion upon Satisfaction of Common Stock Sale Price Condition. A Holder may convert its
Notes during any calendar quarter (and only during such calendar quarter) commencing after the calendar quarter ending on June 30, 2020, if the Last Reported Sale Price per share of Common Stock exceeds one hundred and thirty percent (130%) of
the Conversion Price for each of at least twenty (20) Trading Days (whether or not consecutive) during the thirty (30) consecutive Trading Days ending on, and including, the last Trading Day of the immediately preceding calendar quarter.

 (2) Conversion upon Satisfaction of Note Trading Price Condition. A Holder may convert its Notes during the five
(5) consecutive Business Days immediately after any five (5) consecutive Trading Day period (such five (5) consecutive Trading Day period, the “Measurement Period”) if the Trading Price per $1,000 principal amount of
Notes, as determined following a request by a Holder in accordance with the procedures set forth below, for each Trading Day of the Measurement Period was less than ninety eight percent (98%) of the product of the Last Reported Sale Price per share
of Common Stock on such Trading Day and the Conversion Rate on such Trading Day. The condition set forth in the preceding sentence is referred to in the Indenture as the “Trading Price Condition.” 

The Trading Price will be determined by the Bid Solicitation Agent pursuant to this Section 5.01(C)(i)(2) and the
definition of “Trading Price.” The Bid Solicitation Agent (if not the Company) will have no obligation to determine the Trading Price per $1,000 principal amount of the Notes unless the Company has requested such determination in writing,
and the Company will have no obligation to make such request (or seek bids itself) unless a Holder of at least two million dollars ($2,000,000) aggregate principal amount of Notes (or such lesser principal amount of Notes as may then be outstanding)
provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes would be less than ninety eight percent (98%) of the product of the Last Reported 

  
 - 31 - 

 
Sale Price per share of Common Stock and the Conversion Rate. If a Holder provides such evidence, then the Company will (if acting as Bid Solicitation Agent), or will instruct the Bid
Solicitation Agent to, determine the Trading Price of the Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to ninety eight percent (98%)
of the product of the Last Reported Sale Price per share of Common Stock on such Trading Day and the Conversion Rate on such Trading Day. If the Trading Price Condition has been met as set forth above, then the Company will notify the Holders, the
Trustee and the Conversion Agent of the same. If, on any Trading Day after the Trading Price Condition has been met as set forth above, the Trading Price per $1,000 principal amount of Notes is greater than or equal to ninety eight percent (98%) of
the product of the Last Reported Sale Price per share of Common Stock on such Trading Day and the Conversion Rate on such Trading Day, then the Company will notify the Holders, the Trustee and the Conversion Agent of the same. 

(3) Conversion upon Specified Corporate Events. 

(a) Certain Distributions. If the Company elects to: 

(I) distribute, to all or substantially all holders of Common Stock, any rights, options or warrants (other than rights issued
pursuant to a stockholder rights plan, so long as such rights have not separated from the Common Stock and are not exercisable until the occurrence of a triggering event, except that such rights will be deemed to be distributed under this clause
(I) upon their separation from the Common Stock or upon the occurrence of such triggering event) entitling them, for a period of not more than sixty (60) calendar days after the record date of such distribution, to subscribe for or
purchase shares of Common Stock at a price per share that is less than the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately before
the date such distribution is announced (determined in the manner set forth in the third paragraph of Section 5.05(A)(ii)); or 

(II) distribute, to all or substantially all holders of Common Stock, assets or securities of the Company or rights to
purchase the Company’s securities, which distribution per share of Common Stock has a value, as reasonably determined by the Board of Directors, exceeding ten percent (10%) of the Last Reported Sale Price per share of Common Stock on the
Trading Day immediately before the date such distribution is announced, 

  
 - 32 - 

 then, in either case, (x) the Company will send notice of such distribution, and of
the related right to convert Notes, to Holders, the Trustee and the Conversion Agent at least forty five (45) Scheduled Trading Days before the Ex-Dividend Date for such distribution; and (y) once
the Company has sent such notice, Holders may convert their Notes at any time until the earlier of the Close of Business on the Business Day immediately before such Ex-Dividend Date and the Company’s
announcement that such distribution will not take place; provided, however, that the Notes will not become convertible pursuant to this Section 5.01(C)(i)(3)(a) (but the Company will be required to send notice of
such distribution pursuant to clause (x) above) on account of such distribution if each Holder participates, at the same time and on the same terms as holders of Common Stock, and solely by virtue of being a Holder, in such distribution
without having to convert such Holder’s Notes and as if such Holder held a number of shares of Common Stock equal to the product of (i) the Conversion Rate in effect on the record date for such distribution; and (ii) the aggregate
principal amount (expressed in thousands) of Notes held by such Holder on such record date. 
 (b) Certain Corporate
Events. If a Fundamental Change, Make-Whole Fundamental Change or Common Stock Change Event occurs (other than a merger or other business combination transaction that is effected solely for the purpose of changing the Company’s jurisdiction
of incorporation or an internal reorganization among the Company and its Wholly Owned Subsidiaries or parent entities (in each case, direct or indirect) such that, following such reorganization, such Subsidiaries or parent entities directly or
indirectly own one hundred percent (100%) of the Company’s outstanding equity, and, in each case, that does not constitute a Fundamental Change or a Make-Whole Fundamental Change), then, in each case, Holders may convert their Notes at any time
from, and including, the effective date of such transaction or event to, and including, the thirty fifth (35th) Trading Day after such effective date (or, if such transaction or event also constitutes a Fundamental Change, to, but excluding, the
related Fundamental Change Repurchase Date); provided, however, that if the Company does not provide the notice referred to in the immediately following sentence by such effective date, then the last day on which the Notes are
convertible pursuant to this sentence will be extended by the number of Business Days from, and including, such effective date to, but excluding, the date the Company provides such notice. No later than such effective date, the Company will send
notice to the Holders, the Trustee and the Conversion Agent of such transaction or event, such effective date and the related right to convert Notes. 

(4) Conversions During Free Convertibility Period. A Holder may convert its Notes at any time from, and including,
February 18, 2025 until the Close of Business on the second (2nd) Scheduled Trading Day immediately before the Maturity Date. 

  
 - 33 - 

 For the avoidance of doubt, the Notes may become convertible pursuant to any one or 

more of the preceding sub-paragraphs of this Section 5.01(C)(i) and the Notes
ceasing to be convertible pursuant to a particular sub-paragraph of this Section 5.01(C)(i) will not preclude the Notes from being convertible pursuant to any other sub-paragraph of this Section 5.01(C)(i). 
 (ii) Limitations
and Closed Periods. Notwithstanding anything to the contrary in the Indenture or the Notes: 
 (1) Notes may be
surrendered for conversion only after the Open of Business and before the Close of Business on a day that is a Business Day; 

(2) in no event may any Note be converted after the Close of Business on the second (2nd) Scheduled Trading Day immediately
before the Maturity Date; and 
 (3) if a Fundamental Change Repurchase Notice is validly delivered pursuant to
Section 4.02(F) with respect to any Note, then such Note may not be converted, except to the extent (a) such Note is not subject to such notice; (b) such notice is withdrawn in accordance with
Section 4.02(F); or (c) the Company fails to pay the Fundamental Change Repurchase Price for such Note in accordance with the Indenture. 

Section 5.02. CONVERSION PROCEDURES. 

(A) Generally. 

(i) Global Notes. To convert a beneficial interest in a Global Note that is convertible pursuant to
Section 5.01(C), the owner of such beneficial interest must (1) comply with the Depositary Procedures for converting such beneficial interest (at which time such conversion will become irrevocable); and (2) pay
any amounts due pursuant to Section 5.02(D) or Section 5.02(E). 
 (ii)
Physical Notes. To convert all or a portion of a Physical Note that is convertible pursuant to Section 5.01(C), the Holder of such Note must (1) complete, manually sign and deliver to the Conversion Agent the
conversion notice attached to such Physical Note or a facsimile of such conversion notice; (2) deliver such Physical Note to the Conversion Agent (at which time such conversion will become irrevocable); (3) furnish any endorsements and transfer
documents that the Company or the Conversion Agent may require; and (4) pay any amounts due pursuant to Section 5.02(D) or Section 5.02(E). 

(B) Effect of Converting a Note. At the Close of Business on the Conversion Date for a Note (or any portion thereof) to be converted,
such Note (or such portion) will (unless there occurs a Default in the delivery of the Conversion Consideration or interest due, pursuant to Section 5.03(B) or Section 5.02(D), upon such
conversion) be deemed to cease to be outstanding (and, for the avoidance of doubt, no Person will be deemed to be a Holder of such Note (or such portion thereof) as of the Close of Business on such Conversion Date), except to the extent provided in
Section 5.02(D). 

  
 - 34 - 

 (C) Holder of Record of Conversion Shares. Each conversion will be deemed to have
been effected as to any Notes surrendered for conversion on the Conversion Date; provided, however, that the Person in whose name any share of Common Stock is issuable upon conversion of any Note will be deemed to become the holder of record
of such share as of the Close of Business on (i) the Conversion Date for such conversion, in the case of Physical Settlement; or (ii) the last VWAP Trading Day of the Observation Period for such conversion, in the case of Combination
Settlement. 
 (D) Interest Payable upon Conversion in Certain Circumstances. If the Conversion Date of a Note is after a Regular
Record Date and before the next Interest Payment Date, then (i) the Holder of such Note at the Close of Business on such Regular Record Date will be entitled, notwithstanding such conversion (and, for the avoidance of doubt, notwithstanding
anything set forth in the proviso to this sentence), to receive, on or, at the Company’s election, before such Interest Payment Date, the unpaid interest that would have accrued on such Note to, but excluding, such Interest Payment Date
(assuming, solely for these purposes, that such Note remained outstanding through such Interest Payment Date); and (ii) the Holder surrendering such Note for conversion must deliver to the Conversion Agent, at the time of such surrender, an
amount of cash equal to the amount of such interest referred to in clause (i) above; provided, however, that the Holder surrendering such Note for conversion need not deliver such cash (x) if such Conversion Date occurs after
the Regular Record Date immediately before the Maturity Date; (y) if the Company has specified a Fundamental Change Repurchase Date that is after such Regular Record Date and on or before the Business Day immediately after such Interest Payment
Date; or (z) to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Note. For the avoidance of doubt, as a result of, and without limiting the generality of, the foregoing, if a Note
is converted with a Conversion Date that is after the Regular Record Date immediately before the Maturity Date or any Fundamental Change Repurchase date referred to in the preceding sentence, then the Company will pay, as provided above, the
interest that would have accrued on such Note to, but excluding, the Maturity Date. For the avoidance of doubt, if the Conversion Date of a Note to be converted is on an Interest Payment Date, then the Holder of such Note at the Close of Business on
the Regular Record Date immediately before such Interest Payment Date will be entitled to receive, on such Interest Payment Date, the unpaid interest that has accrued on such Note to, but excluding, such Interest Payment Date, and such Note, when
surrendered for conversion, need not be accompanied by any cash amount pursuant to the first sentence of this Section 5.02(D). 

(E) Taxes and Duties. If a Holder converts a Note, the Company will pay any documentary, stamp or similar issue or transfer tax or duty
due on the issue of any shares of Common Stock upon such conversion; provided, however, that if any tax or duty is due because such Holder requested such shares to be registered in a name other than such Holder’s name, then such
Holder will pay such tax or duty and, until having received a sum sufficient to pay such tax or duty, the Conversion Agent may refuse to deliver any such shares to be issued in a name other than that of such Holder. 

(F) Conversion Agent to Notify Company of Conversions. If any Note is submitted for conversion to the Conversion Agent or the Conversion
Agent receives any notice of conversion with respect to a Note, then the Conversion Agent will promptly notify the Company and the Trustee of such occurrence, together with any other information reasonably requested by the Company, and will
cooperate with the Company to determine the Conversion Date for such Note. 

  
 - 35 - 

 Section 5.03. SETTLEMENT UPON CONVERSION. 

(A) Settlement Method. Upon the conversion of any Note, the Company will settle such conversion by paying or delivering, as applicable
and as provided in this Article 5, either (x) shares of Common Stock, together, if applicable, with cash in lieu of fractional shares as provided in Section 5.03(B)(i)(1) (a “Physical
Settlement”); (y) solely cash as provided in Section 5.03(B)(i)(2) (a “Cash Settlement”); or (z) a combination of cash and shares of Common Stock, together, if applicable, with cash in lieu of
fractional shares as provided in Section 5.03(B)(i)(3) (a “Combination Settlement”). 
 The
Company will have the right to elect the Settlement Method applicable to any conversion of a Note; provided, however, that: 

(i) all conversions of Notes with a Conversion Date that occurs on or after February 18, 2025 will be settled using the
same Settlement Method, and the Company will send notice of such Settlement Method to Holders and the Conversion Agent no later than the Open of Business on February 18, 2025; 

(ii) if the Company elects a Settlement Method with respect to the conversion of any Note whose Conversion Date occurs before
February 18, 2025, then the Company will send notice of such Settlement Method to the Holder of such Note and the Conversion Agent no later than the Close of Business on the Business Day immediately after such Conversion Date; 

(iii) the Company will use the same Settlement Method for all conversions of Notes with the same Conversion Date (and, for the
avoidance of doubt, the Company will not be obligated to use the same Settlement Method with respect to conversions of Notes with different Conversion Dates, except as provided in clause (i) above); 

(iv) if the Company does not timely elect a Settlement Method with respect to the conversion of a Note, then the Company will
be deemed to have elected the Default Settlement Method (and, for the avoidance of doubt, the failure to timely make such election will not constitute a Default or Event of Default); 

(v) if the Company timely elects Combination Settlement with respect to the conversion of a Note but does not timely notify the
Holder of such Note of the applicable Specified Dollar Amount, then the Specified Dollar Amount for such conversion will be deemed to be $1,000 per $1,000 principal amount of Notes (and, for the avoidance of doubt, the failure to timely send such
notification will not constitute a Default or Event of Default); and 
 (vi) the Settlement Method will be subject to
Section 5.08(A)(2). 

  
 - 36 - 

 In addition, the Company will have the right, exercisable at its election by sending notice
of such exercise to the Holders (with a copy to the Trustee and the Conversion Agent), to irrevocably fix the Settlement Method that will apply to all conversions of Notes with a Conversion Date that occurs on or after the date such notice is sent
to Holders, provided that such Settlement Method must be a Settlement Method that the Company is then permitted to elect (for the avoidance of doubt, including pursuant to, and subject to, the other provisions of this
Section 5.03(A)). Such notice, if sent, must set forth the applicable Settlement Method and expressly state that the election is irrevocable and applicable to all conversions of Notes with a Conversion Date that occurs on
or after the date such notice is sent to Holders. For the avoidance of doubt, such an irrevocable election, if made, will be effective without the need to amend the Indenture or the Notes, including pursuant to
Section 8.01(G) (it being understood, however, that the Company may nonetheless choose to execute such an amendment at its option). 

(B) Conversion Consideration. 

(i) Generally. Subject to Section 5.03(B)(ii) and
Section 5.03(B)(iii), the type and amount of consideration (the “Conversion Consideration”) due in respect of each $1,000 principal amount of a Note to be converted will be as follows: 

(1) if Physical Settlement applies to such conversion, a number of shares of Common Stock equal to the Conversion Rate in
effect on the Conversion Date for such conversion; 
 (2) if Cash Settlement applies to such conversion, cash in an amount
equal to the sum of the Daily Conversion Values for each VWAP Trading Day in the Observation Period for such conversion; or 

(3) if Combination Settlement applies to such conversion, consideration consisting of (a) a number of shares of Common
Stock equal to the sum of the Daily Share Amounts for each VWAP Trading Day in the Observation Period for such conversion; and (b) an amount of cash equal to the sum of the Daily Cash Amounts for each VWAP Trading Day in such Observation
Period. 
 (ii) Cash in Lieu of Fractional Shares. If Physical Settlement or Combination Settlement applies to the
conversion of any Note and the number of shares of Common Stock deliverable pursuant to Section 5.03(B)(i) upon such conversion is not a whole number, then such number will be rounded down to the nearest whole number and
the Company will deliver, in addition to the other consideration due upon such conversion, cash in lieu of the related fractional share in an amount equal to the product of (1) such fraction and (2) (x) the Daily VWAP on the Conversion Date for
such conversion (or, if such Conversion Date is not a VWAP Trading Day, the immediately preceding VWAP Trading Day), in the case of Physical Settlement; or (y) the Daily VWAP on the last VWAP Trading Day of the Observation Period for such
conversion, in the case of Combination Settlement. 
 (iii) Conversion of Multiple Notes by a Single Holder. If a
Holder converts more than one (1) Note on a single Conversion Date, then the Conversion Consideration due in respect of such conversion will (in the case of any Global Note, to the extent permitted by, and practicable under, the Depositary
Procedures) be computed based on the total principal amount of Notes converted on such Conversion Date by such Holder. 

  
 - 37 - 

 (iv) Notice of Calculation of Conversion Consideration. If Cash
Settlement or Combination Settlement applies to the conversion of any Note, then the Company will determine the Conversion Consideration due thereupon promptly following the last VWAP Trading Day of the applicable Observation Period and will
promptly thereafter send notice to the Trustee and the Conversion Agent of the same and the calculation thereof in reasonable detail. Neither the Trustee nor the Conversion Agent will have any duty to make any such determination. 

(C) Delivery of the Conversion Consideration. Except as set forth in Sections 5.05(C) and 5.08, the Company will
pay or deliver, as applicable, the Conversion Consideration due upon the conversion of any Note to the Holder as follows: (i) if Cash Settlement or Combination Settlement applies to such conversion, on or before the second (2nd) Business Day
immediately after the last VWAP Trading Day of the Observation Period for such conversion; and (ii) if Physical Settlement applies to such conversion, on or before the second (2nd) Business Day immediately after the Conversion Date for such
conversion. 
 (D) Deemed Payment of Principal and Interest; Settlement of Accrued Interest Notwithstanding Conversion. If a Holder
converts a Note, then the Company will not adjust the Conversion Rate to account for any accrued and unpaid interest on such Note, and, except as provided in Section 5.02(D), the Company’s delivery of the Conversion
Consideration due in respect of such conversion will be deemed to fully satisfy and discharge the Company’s obligation to pay the principal of, and accrued and unpaid interest, if any, on, such Note to, but excluding the Conversion Date. As a
result, except as provided in Section 5.02(D), any accrued and unpaid interest on a converted Note will be deemed to be paid in full rather than cancelled, extinguished or forfeited. In addition, subject to
Section 5.02(D), if the Conversion Consideration for a Note consists of both cash and shares of the Common Stock, then accrued and unpaid interest that is deemed to be paid therewith will be deemed to be paid first out of
such cash. 
 Section 5.04. RESERVE AND STATUS OF COMMON
STOCK ISSUED UPON CONVERSION. 
 (A) Stock Reserve. At all times when
any Notes are outstanding, the Company will reserve, out of its authorized but unissued and unreserved shares of Common Stock, a number of shares of Common Stock sufficient to permit the conversion of all then-outstanding Notes, assuming
(x) Physical Settlement will apply to such conversion; and (y) the Conversion Rate is increased by the maximum amount pursuant to which the Conversion Rate may be increased pursuant to Section 5.07. 

(B) Status of Conversion Shares; Listing. Each Conversion Share, if any, delivered upon conversion of any Note will be a newly issued or
treasury share and will be duly and validly issued, fully paid, non-assessable, free from preemptive rights and free of any lien or adverse claim (except to the extent of any lien or adverse claim created by
the action or inaction of the Holder of such Note or the Person to whom such Conversion Share will be delivered). If the Common Stock is then listed on any securities exchange, or quoted on any inter-dealer quotation system, then the Company will
use commercially reasonable efforts to cause each Conversion Share, when delivered upon conversion of any Note, to be admitted for listing on such exchange or quotation on such system. 

  
 - 38 - 

 Section 5.05. ADJUSTMENTS TO THE
CONVERSION RATE. 
 (A) Events Requiring an Adjustment to the Conversion Rate. The Conversion Rate
will be adjusted from time to time as follows: 
 (i) Stock Dividends, Splits and Combinations. If the Company issues
solely shares of Common Stock as a dividend or distribution on all or substantially all shares of the Common Stock, or if the Company effects a stock split or a stock combination of the Common Stock (in each case excluding an issuance solely
pursuant to a Common Stock Change Event, as to which Section 5.08 will apply), then the Conversion Rate will be adjusted based on the following formula: 

 
 

 
 where: 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately before the Open of Business on the Ex-Dividend Date for such dividend or distribution, or immediately before the Open of Business on the effective
date of such stock split or stock combination, as applicable;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date or effective date, as applicable;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately before the Open of Business on such Ex-Dividend Date or effective date, as applicable, without giving effect to such dividend,
distribution, stock split or stock combination; and
			
	OS1	  	=	  	the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, stock split or stock combination.

 For the avoidance of doubt, any adjustment to the Conversion Rate pursuant to this
Section 5.05(A)(i) will become effective as of the time set forth in CR1 above. If any dividend, distribution, stock split or stock combination of the
type described in this Section 5.05(A)(i) is declared or announced, but not so paid or made, then the Conversion Rate will be readjusted, effective as of the date the Board of Directors determines not to pay such dividend
or distribution or to effect such stock split or stock combination, to the Conversion Rate that would then be in effect had such dividend, distribution, stock split or stock combination not been declared or announced. 

  
 - 39 - 

 (ii) Rights, Options and Warrants. If the Company distributes, to all
or substantially all holders of Common Stock, rights, options or warrants (other than rights issued or otherwise distributed pursuant to a stockholder rights plan, as to which Sections 5.05(A)(iii)(1) and 5.05(E) will apply) entitling
such holders, for a period of not more than sixty (60) calendar days after the record date of such distribution, to subscribe for or purchase shares of Common Stock at a price per share that is less than the average of the Last Reported Sale
Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately before the date such distribution is announced, then the Conversion Rate will be increased based on the following
formula: 
  
 

 
 where: 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately before the Open of Business on the Ex-Dividend Date for such distribution;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;
			
	OS	  	=	  	the number of shares of Common Stock outstanding immediately before the Open of Business on such Ex-Dividend Date;
			
	X	  	=	  	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
			
	Y	  	=	  	a number of shares of Common Stock obtained by dividing (x) the aggregate price payable to exercise such rights, options or warrants by (y) the average of the Last Reported Sale Prices per share of Common Stock for the ten
(10) consecutive Trading Days ending on, and including, the Trading Day immediately before the date such distribution is announced.

 For the avoidance of doubt, any adjustment to the Conversion Rate pursuant to this
Section 5.05(A)(ii) will become effective as of the time set forth in CR1 above. To the extent that shares of Common Stock are not delivered after the
expiration of such rights, options or warrants (including as a result of such rights, options or warrants not being exercised), the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the increase to the
Conversion Rate for such distribution been made on the basis of delivery of only the number of shares of Common Stock actually delivered upon exercise of such rights, option or warrants. If such rights, options or warrants are not so distributed,
the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the Ex-Dividend Date for the distribution of such rights, options or warrants not occurred. 

  
 - 40 - 

 For purposes of this Section 5.05(A)(ii) and
Section 5.01(C)(i)(3)(a)(I), in determining whether any rights, options or warrants entitle holders of Common Stock to subscribe for or purchase shares of Common Stock at a price per share that is less than the average of
the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately before the date the distribution of such rights, options or warrants is announced, and in
determining the aggregate price payable to exercise such rights, options or warrants, there will be taken into account any consideration the Company receives for such rights, options or warrants and any amount payable on exercise thereof, with the
value of such consideration, if not cash, to be determined by the Board of Directors. 
 (iii) Spin-Offs and Other
Distributed Property. 
 (1) Distributions Other than Spin-Offs. If the Company distributes shares of its Capital
Stock, evidences of its indebtedness or other assets or property of the Company, or rights, options or warrants to acquire Capital Stock of the Company or other securities, to all or substantially all holders of the Common Stock, excluding: 

(u) dividends, distributions, rights, options or warrants for which an adjustment to the Conversion Rate is required pursuant
to Section 5.05(A)(i) or 5.05(A)(ii); 
 (v) dividends or distributions paid exclusively in cash
for which an adjustment to the Conversion Rate is required pursuant to Section 5.05(A)(iv); 
 (w)
rights issued or otherwise distributed pursuant to a stockholder rights plan, except to the extent provided in Section 5.05(E); 

(x) Spin-Offs for which an adjustment to the Conversion Rate is required pursuant to
Section 5.05(A)(iii)(2); 
 (y) a distribution solely pursuant to a tender offer or exchange offer
for shares of Common Stock, as to which Section 5.05(A)(v) will apply; and 
 (z) a distribution
solely pursuant to a Common Stock Change Event, as to which Section 5.08 will apply, 
 then the Conversion Rate
will be increased based on the following formula: 
  
 

 

  
 - 41 - 

 where: 

 

					
	CR0	  	=	  	the Conversion Rate in effect immediately before the Open of Business on the Ex-Dividend Date for such distribution;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;
			
	SP	  	=	  	the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately before such
Ex-Dividend Date; and
			
	FMV	  	=	  	the fair market value (as determined by the Board of Directors), as of such Ex-Dividend Date, of the shares of Capital Stock, evidences of indebtedness, assets, property, rights, options or
warrants distributed per share of Common Stock pursuant to such distribution;

 provided, however, that if FMV is equal to or greater than SP, then, in lieu
of the foregoing adjustment to the Conversion Rate, each Holder will receive, for each $1,000 principal amount of Notes held by such Holder on the record date for such distribution, at the same time and on the same terms as holders of Common Stock,
the amount and kind of shares of Capital Stock, evidences of indebtedness, assets, property, rights, options or warrants that such Holder would have received if such Holder had owned, on such record date, a number of shares of Common Stock equal to
the Conversion Rate in effect on such record date. 
 If such distribution is not so paid or made, then the Conversion Rate will be
readjusted to the Conversion Rate that would then be in effect if such distribution had not been declared. 
 For the avoidance of doubt, any
adjustment to the Conversion Rate pursuant to this Section 5.05(A)(iii)(1) will become effective as of the time set forth in CR1 above. 

(2) Spin-Offs. If the Company distributes or dividends shares of Capital Stock of any class or series, or similar equity
interests, of or relating to a Subsidiary or other business unit of the Company to all or substantially all holders of the Common Stock (other than solely pursuant to (x) a Common Stock Change Event, as to which
Section 5.08 will apply; or (y) a tender offer or exchange offer for shares of Common Stock, as to which Section 5.05(A)(v) will apply), and such Capital Stock or equity interests are listed
or quoted (or will be listed or quoted upon the consummation of the transaction) on a U.S. national securities exchange (a “Spin-Off”), then the Conversion Rate will be increased based on the
following formula: 
  
 

 

  
 - 42 - 

 where: 

 

					
	CR0	  	=	  	the Conversion Rate in effect immediately before the Close of Business on the last Trading Day of the Spin-Off Valuation Period for such
Spin-Off;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the Close of Business on the last Trading Day of the Spin-Off Valuation Period;
			
	FMV	  	=	  	the product of (x) the average of the Last Reported Sale Prices per share or unit of the Capital Stock or equity interests distributed in such Spin-Off over the first ten
(10) consecutive Trading Day period (the “Spin-Off Valuation Period”) beginning on, and including, the Ex-Dividend Date for such Spin-Off (such average to be determined as if references to Common Stock in the definitions of Last Reported Sale Price, Trading Day and Market Disruption Event were instead references to such Capital Stock or
equity interests); and (y) the number of shares or units of such Capital Stock or equity interests distributed per share of Common Stock in such Spin-Off; and
			
	SP	  	=	  	the average of the Last Reported Sale Prices per share of Common Stock for each Trading Day in the Spin-Off Valuation Period.

 Notwithstanding anything to the contrary in this Section 5.05(A)(iii)(2), (i)
if any VWAP Trading Day of the Observation Period for a Note whose conversion will be settled pursuant to Cash Settlement or Combination Settlement occurs during the Spin-Off Valuation Period for such Spin-Off, then, solely for purposes of determining the Conversion Rate for such VWAP Trading Day for such conversion, such Spin-Off Valuation Period will be deemed to consist
of the Trading Days occurring in the period from, and including, the Ex-Dividend Date for such Spin-Off to, and including, such VWAP Trading Day; and (ii) if the
Conversion Date for a Note whose conversion will be settled pursuant to Physical Settlement occurs during the Spin-Off Valuation Period for such Spin-Off, then, solely
for purposes of determining the Conversion Consideration for such conversion, such Spin-Off Valuation Period will be deemed to consist of the Trading Days occurring in the period from, and including, the Ex-Dividend Date for such Spin-Off to, and including, such Conversion Date. 

If any dividend or distribution of the type set forth in this Section 5.05(A)(iii)(2) is declared but not made or
paid, then the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect if the distribution had not been declared. 

For the avoidance of doubt, any adjustment to the Conversion Rate pursuant to this Section 5.05(A)(iii)(2) will
become effective as of the time set forth in CR1 above. 

  
 - 43 - 

 (iv) Cash Dividends or Distributions. If any cash dividend or
distribution is made to all or substantially all holders of Common Stock, then the Conversion Rate will be increased based on the following formula: 
  

 
 where: 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately before the Open of Business on the Ex-Dividend Date for such dividend or distribution;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;
			
	SP	  	=	  	the Last Reported Sale Price per share of Common Stock on the Trading Day immediately before such Ex-Dividend Date; and
			
	D	  	=	  	the cash amount distributed per share of Common Stock in such dividend or distribution;

 provided, however, that if D is equal to or greater than SP, then, in lieu of
the foregoing adjustment to the Conversion Rate, each Holder will receive, for each $1,000 principal amount of Notes held by such Holder on the record date for such dividend or distribution, at the same time and on the same terms as holders of
Common Stock, the amount of cash that such Holder would have received if such Holder had owned, on such record date, a number of shares of Common Stock equal to the Conversion Rate in effect on such record date. 

If such dividend or distribution is declared but not made or paid, then the Conversion Rate will be readjusted to the Conversion Rate that
would then be in effect if such dividend or distribution had not been declared. 
 For the avoidance of doubt, any adjustment to the
Conversion Rate pursuant to this Section 5.05(A)(iv) will become effective as of the time set forth in CR1 above. 

(v) Tender Offers or Exchange Offers. If the Company or any of its Subsidiaries makes a payment in respect of a tender
offer or exchange offer for shares of Common Stock, and the value (determined as of the Expiration Time by the Board of Directors) of the cash and other consideration paid per share of Common Stock in such tender or exchange offer exceeds the Last
Reported Sale Price per share of Common Stock on the Trading Day immediately after the last date (the “Expiration Date”) on which tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended),
then the Conversion Rate will be increased based on the following formula: 

  
 - 44 - 

 

 
 where: 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately before the Close of Business on the last Trading Day of the Tender/Exchange Offer Valuation Period for such tender or exchange offer;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the Close of Business on the last Trading Day of the Tender/Exchange Offer Valuation Period;
			
	AC	  	=	  	the aggregate value (determined as of the time (the “Expiration Time”) such tender or exchange offer expires by the Board of Directors) of all cash and other consideration paid for shares of Common Stock purchased
or exchanged in such tender or exchange offer;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately before the Expiration Time (including all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer);
			
	OS1	  	=	  	the number of shares of Common Stock outstanding immediately after the Expiration Time (excluding all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer); and
			
	SP	  	=	  	the average of the Last Reported Sale Prices per share of Common Stock over the ten (10) consecutive Trading Day period (the “Tender/Exchange Offer Valuation Period”) beginning on, and including, the Trading
Day immediately after the Expiration Date;

 provided, however, that the Conversion Rate will in no event be adjusted down pursuant to
this Section 5.05(A)(v), except to the extent provided in the immediately following paragraph. Notwithstanding anything to the contrary in this Section 5.05(A)(v), (i) if any VWAP Trading Day of
the Observation Period for a Note whose conversion will be settled pursuant to Cash Settlement or Combination Settlement occurs during the Tender/Exchange Offer Valuation Period for such tender or exchange offer, then, solely for purposes of
determining the Conversion Rate for such VWAP Trading Day for such conversion, such Tender/Exchange Offer Valuation Period will be deemed to consist of the Trading Days occurring in the period from, and including, the Trading Day immediately after
the Expiration Date for such tender or exchange offer to, and including, such VWAP Trading Day; and (ii) if the Conversion Date for a Note whose conversion will be settled pursuant to Physical Settlement occurs during the Tender/Exchange Offer
Valuation Period for such tender or exchange offer, then, solely for purposes of determining the Conversion Consideration for such conversion, such Tender/Exchange Offer Valuation Period will be deemed to consist of the Trading Days occurring in the
period from, and including, the Trading Day immediately after the Expiration Date to, and including, such Conversion Date. 

  
 - 45 - 

 To the extent such tender or exchange offer is announced but not consummated (including as a
result of the Company being precluded from consummating such tender or exchange offer under applicable law), or any purchases or exchanges of shares of Common Stock in such tender or exchange offer are rescinded, the Conversion Rate will be
readjusted to the Conversion Rate that would then be in effect had the adjustment been made on the basis of only the purchases or exchanges of shares of Common Stock, if any, actually made, and not rescinded, in such tender or exchange offer. 

For the avoidance of doubt, any adjustment to the Conversion Rate pursuant to this Section 5.05(A)(v) will become
effective as of the time set forth in CR1 above. 
 (B) No
Adjustments in Certain Cases. 
 (i) Where Holders Participate in the Transaction or Event Without Conversion.
Notwithstanding anything to the contrary in Section 5.05(A), the Company will not be obligated to adjust the Conversion Rate on account of a transaction or other event otherwise requiring an adjustment pursuant to
Section 5.05(A) (other than a stock split or combination of the type set forth in Section 5.05(A)(i) or a tender or exchange offer of the type set forth in
Section 5.05(A)(v)) if each Holder participates, at the same time and on the same terms as holders of Common Stock, and solely by virtue of being a Holder of Notes, in such transaction or event without having to convert
such Holder’s Notes and as if such Holder held a number of shares of Common Stock equal to the product of (i) the Conversion Rate in effect on the related record date; and (ii) the aggregate principal amount (expressed in thousands)
of Notes held by such Holder on such date. 
 (ii) Certain Events. The Company will not be required to adjust the
Conversion Rate except as provided in Section 5.05 or Section 5.07. Without limiting the foregoing, the Company will not be obligated to adjust the Conversion Rate on account of: 

(1) except as otherwise provided in Section 5.05, the sale of shares of Common Stock for a purchase
price that is less than the market price per share of Common Stock or less than the Conversion Price; 
 (2) the issuance of
any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any
such plan; 
 (3) the issuance of any shares of Common Stock or options or rights to purchase shares of Common Stock pursuant
to any present or future employee, director or consultant benefit plan or program of, or assumed by, the Company or any of its Subsidiaries; 

  
 - 46 - 

 (4) the issuance of any shares of Common Stock pursuant to any option,
warrant, right or convertible or exchangeable security of the Company outstanding as of the Issue Date (other than an adjustment pursuant to Section 5.05(A)(iii)(1) in connection with the separation of rights under the
Company’s stockholder rights plan existing as of the Issue Date); 
 (5) for a third party tender offer by any party
other than a tender offer by the Company or one or more of its Subsidiaries described in Section 5.05(A)(v); 

(6) solely a change in the par value of the Common Stock; or 

(7) accrued and unpaid interest on the Notes. 

(C) Adjustments Not Yet Effective. Notwithstanding anything to the contrary in the Indenture or the Notes, if: 

(i) a Note is to be converted pursuant to Physical Settlement or Combination Settlement; 

(ii) the record date, effective date or Expiration Time for any event that requires an adjustment to the Conversion Rate
pursuant to Section 5.05(A) has occurred on or before the Conversion Date for such conversion (in the case of Physical Settlement) or on or before any VWAP Trading Day in the Observation Period for such conversion (in the
case of Combination Settlement), but an adjustment to the Conversion Rate for such event has not yet become effective as of such Conversion Date or VWAP Trading Day, as applicable; 

(iii) the Conversion Consideration due upon such conversion includes any whole shares of Common Stock (in the case of Physical
Settlement) or due in respect of such VWAP Trading Day includes any whole or fractional shares of Common Stock (in the case of Combination Settlement); and 

(iv) such shares are not entitled to participate in such event (because they were not held on the related record date or
otherwise), 
 then, solely for purposes of such conversion, the Company will, without duplication, give effect to such adjustment on such Conversion Date
(in the case of Physical Settlement) or such VWAP Trading Day (in the case of Combination Settlement). In such case, if the date on which the Company is otherwise required to deliver the consideration due upon such conversion is before the first
date on which the amount of such adjustment can be determined, then the Company will delay the settlement of such conversion until the second (2nd) Business Day after such first date. 

  
 - 47 - 

 (D) Conversion Rate Adjustments where Converting Holders Participate in the Relevant
Transaction or Event. Notwithstanding anything to the contrary in the Indenture or the Notes, if: 
 (i) a Conversion
Rate adjustment for any dividend or distribution becomes effective on any Ex-Dividend Date pursuant to Section 5.05(A); 

(ii) a Note is to be converted pursuant to Physical Settlement or Combination Settlement; 

(iii) the Conversion Date for such conversion (in the case of Physical Settlement) or any VWAP Trading Day in the Observation
Period for such conversion (in the case of Combination Settlement) occurs on or after such Ex-Dividend Date and on or before the related record date; 

(iv) the Conversion Consideration due upon such conversion includes any whole shares of Common Stock (in the case of Physical
Settlement) or due in respect of such VWAP Trading Day includes any whole or fractional shares of Common Stock (in the case of Combination Settlement), in each case based on a Conversion Rate that is adjusted for such dividend or distribution; and

 (v) such shares would be entitled to participate in such dividend or distribution (including pursuant to
Section 5.02(C)), 
 then (x) in the case of Physical Settlement, such Conversion Rate adjustment will not be given effect for
such conversion and the shares of Common Stock issuable upon such conversion based on such unadjusted Conversion Rate will not be entitled to participate in such dividend or distribution, but there will be added, to the Conversion Consideration
otherwise due upon such conversion, the same kind and amount of consideration that would have been delivered in such dividend or distribution with respect to such shares of Common Stock had such shares been entitled to participate in such dividend
or distribution; and (y) in the case of Combination Settlement, the Conversion Rate adjustment relating to such Ex-Dividend Date will be made for such conversion in respect of such VWAP Trading Day, but
the shares of Common Stock issuable with respect to such VWAP Trading Day based on such adjusted Conversion Rate will not be entitled to participate in such dividend or distribution. 

(E) Stockholder Rights Plans. If any shares of Common Stock are to be issued upon conversion of any Note and, at the time of such
conversion, the Company has in effect any stockholder rights plan, then the Holder of such Note will be entitled to receive, in addition to, and concurrently with the delivery of, the Conversion Consideration otherwise payable under the Indenture
upon such conversion, the rights set forth in such stockholder rights plan, unless such rights have separated from the Common Stock at such time, in which case, and only in such case, the Conversion Rate will be adjusted pursuant to
Section 5.05(A)(iii)(1) on account of such separation as if, at the time of such separation, the Company had made a distribution of the type referred to in such Section to all holders of the Common Stock, subject to
readjustment in accordance with such Section if such rights expire, terminate or are redeemed. 

  
 - 48 - 

 (F) Limitation on Effecting Transactions Resulting in Certain Adjustments. The
Company will not engage in or be a party to any transaction or event that would require the Conversion Rate to be adjusted pursuant to Section 5.05(A) or Section 5.07 to an amount that would result
in the Conversion Price per share of Common Stock being less than the par value per share of Common Stock. 
 (G) Equitable Adjustments to
Prices. Whenever any provision of the Indenture requires the Company to calculate the average of the Last Reported Sale Prices, or any function thereof, over a period of multiple days (including to calculate the Stock Price or an adjustment to
the Conversion Rate), or to calculate Daily VWAPs over an Observation Period, the Company will make proportionate adjustments, if any, to such calculations to account for any adjustment to the Conversion Rate pursuant to
Section 5.05(A)(i) that becomes effective, or any event requiring such an adjustment to the Conversion Rate where the Ex-Dividend Date or effective date, as applicable, of such event
occurs, at any time during such period or Observation Period, as applicable. 
 (H) Calculation of Number of Outstanding Shares of Common
Stock. For purposes of Section 5.05(A), the number of shares of Common Stock outstanding at any time will (i) include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common
Stock; and (ii) exclude shares of Common Stock held in the Company’s treasury (unless the Company pays any dividend or makes any distribution on shares of Common Stock held in its treasury). 

(I) Calculations. All calculations with respect to the Conversion Rate and adjustments thereto will be made to the nearest 1/10,000th of
a share of Common Stock (with 5/100,000ths rounded upward). 
 (J) Notice of Conversion Rate Adjustments. Upon the effectiveness of
any adjustment to the Conversion Rate pursuant to Section 5.05(A), the Company will promptly send notice to the Holders, the Trustee and the Conversion Agent containing (i) a brief description of the transaction or
other event on account of which such adjustment was made; (ii) the Conversion Rate in effect immediately after such adjustment; and (iii) the effective time of such adjustment. 

Section 5.06. VOLUNTARY ADJUSTMENTS. 

(A) Generally. To the extent permitted by law and applicable stock exchange rules, the Company, from time to time, may (but is not
required to) increase the Conversion Rate by any amount if (i) the Board of Directors determines that such increase is either (x) in the best interest of the Company; or (y) advisable to avoid or diminish any income tax imposed on
holders of Common Stock or rights to purchase Common Stock as a result of any dividend or distribution of shares (or rights to acquire shares) of Common Stock or any similar event; (ii) such increase is in effect for a period of at least twenty
(20) Business Days; and (iii) such increase is irrevocable during such period. 
 (B) Notice of Voluntary Increases. If the
Board of Directors determines to increase the Conversion Rate pursuant to Section 5.06(A), then, no later than the first Business Day of the related twenty (20) Business Day period referred to in
Section 5.06(A), the Company will send notice to each Holder, the Trustee and the Conversion Agent of such increase, the amount thereof and the period during which such increase will be in effect. 

  
 - 49 - 

 Section 5.07. ADJUSTMENTS TO THE
CONVERSION RATE IN CONNECTION WITH A MAKE-WHOLE FUNDAMENTAL CHANGE. 

(A) Generally. If a Make-Whole Fundamental Change occurs and the Conversion Date for the conversion of a Note occurs during the related
Make-Whole Fundamental Change Conversion Period, then, subject to this Section 5.07, the Conversion Rate applicable to such conversion will be increased by a number of shares (the “Additional Shares”) set
forth in the table below corresponding (after interpolation as provided in, and subject to, the provisions below) to the effective date and the Stock Price of such Make-Whole Fundamental Change: 

 

																																									
	 	  	Stock Price	 
	 Effective Date
	  	$10.00	 	  	$11.00	 	  	$12.75	 	  	$18.00	 	  	$30.00	 	  	$50.00	 	  	$75.00	 	  	$100.00	 	  	$150.00	 	  	$215.00

 If such effective date or Stock Price is not set forth in the table above, then: 

(i) if such Stock Price is between two Stock Prices in the table above or the effective date is between two dates in the table
above, then the number of Additional Shares will be determined by straight-line interpolation between the numbers of Additional Shares set forth for the higher and lower Stock Prices in the table above or the earlier and later dates in the table
above, based on a 365- or 366-day year, as applicable; and 

(ii) if the Stock Price is greater than $215.00 (subject to adjustment in the same manner as the Stock Prices set forth in the
column headings of the table above are adjusted pursuant to Section 5.07(B)), or less than $10.00 (subject to adjustment in the same manner), per share, then no Additional Shares will be added to the Conversion Rate. 

Notwithstanding anything to the contrary in the Indenture or the Notes, in no event will the Conversion Rate be increased to an amount that
exceeds 100.0000 shares of Common Stock per $1,000 principal amount of Notes, which amount is subject to adjustment in the same manner as, and at the same time and for the same events for which, the Conversion Rate is required to be adjusted
pursuant to Section 5.05(A). 
 (B) Adjustment of Stock Prices and Additional Shares. The Stock Prices in
the first row (i.e., the column headers) of the table set forth in Section 5.07(A) will be adjusted in the same manner as, and at the same time and for the same events for which, the Conversion Price is adjusted as a
result of the operation of Section 5.05(A). The numbers of Additional Shares in the table set forth in Section 5.07(A) will be adjusted in the same manner as, and at the same time and for the same
events for which, the Conversion Rate is adjusted pursuant to Section 5.05(A). 

  
 - 50 - 

 (C) Notice of the Occurrence of a Make-Whole Fundamental Change. The Company will
notify the Holders, the Trustee and the Conversion Agent of each Make-Whole Fundamental Change in accordance with Section 5.01(C)(i)(3)(b). 

Section 5.08. EFFECT OF COMMON STOCK CHANGE EVENT. 

(A) Generally. If there occurs any: 

(i) recapitalization, reclassification or change of the Common Stock (other than (x) changes solely resulting from a
subdivision or combination of the Common Stock, (y) a change only in par value or from par value to no par value or no par value to par value and (z) stock splits and stock combinations that do not involve the issuance of any other series
or class of securities); 
 (ii) consolidation, merger, combination or binding or statutory share exchange involving the
Company; 
 (iii) sale, lease or other transfer of all or substantially all of the assets of the Company and its
Subsidiaries, taken as a whole, to any Person; or 
 (iv) other similar event, 

and, as a result of which, the Common Stock is converted into, or is exchanged for, or represents solely the right to receive, other securities, cash or other
property, or any combination of the foregoing (such an event, a “Common Stock Change Event,” and such other securities, cash or property, the “Reference Property,” and the amount and kind of Reference Property that
a holder of one (1) share of Common Stock would be entitled to receive on account of such Common Stock Change Event (without giving effect to any arrangement not to issue or deliver a fractional portion of any security or other property), a
“Reference Property Unit”), then, notwithstanding anything to the contrary in the Indenture or the Notes, 

(1) from and after the effective time of such Common Stock Change Event, (I) the Conversion Consideration due upon
conversion of any Note, and the conditions to any such conversion, will be determined in the same manner as if each reference to any number of shares of Common Stock in this Article 5 (or in any related definitions) were instead a reference
to the same number of Reference Property Units; and (II) for purposes of the definition of “Fundamental Change” and “Make-Whole Fundamental Change,” the terms “Common Stock” and “common equity” will be
deemed to mean the common equity (including depositary receipts representing common equity), if any, forming part of such Reference Property; 

(2) if such Reference Property Unit consists entirely of cash, then the Company will be deemed to elect Physical Settlement in
respect of all conversions whose Conversion Date occurs on or after the effective date of such Common Stock Change Event and will pay the cash due upon such conversions no later than the second (2nd) Business Day after the relevant Conversion Date;
and 

  
 - 51 - 

 (3) for these purposes, (I) the Daily VWAP of any Reference Property
Unit or portion thereof that consists of a class of common equity securities will be determined by reference to the definition of “Daily VWAP,” substituting, if applicable, the Bloomberg page for such class of securities in such
definition; and (II) the Daily VWAP of any Reference Property Unit or portion thereof that does not consist of a class of common equity securities, and the Last Reported Sale Price of any Reference Property Unit or portion thereof that does not
consist of a class of securities, will be the fair value of such Reference Property Unit or portion thereof, as applicable, determined in good faith by the Company (or, in the case of cash denominated in U.S. dollars, the face amount thereof). 

If the Reference Property consists of more than a single type of consideration to be determined based in part upon any form of stockholder
election, then the composition of the Reference Property Unit will be deemed to be the weighted average of the types and amounts of consideration actually received, per share of Common Stock, by the holders of Common Stock. The Company will notify
Holders of such weighted average as soon as practicable after such determination is made. 
 At or before the effective time of such Common
Stock Change Event, the Company and the resulting, surviving or transferee Person (if not the Company) of such Common Stock Change Event (the “Successor Person”) will execute and deliver to the Trustee a supplemental indenture
pursuant to Section 8.01(F), which supplemental indenture will (x) provide for subsequent conversions of Notes in the manner set forth in this Section 5.08; (y) provide for subsequent
adjustments to the Conversion Rate pursuant to Section 5.05(A) in a manner consistent with this Section 5.08; and (z) contain such other provisions, if any, that the Company reasonably
determines are appropriate to preserve the economic interests of the Holders and to give effect to the provisions of this Section 5.08(A). If the Reference Property includes shares of stock or other securities or assets
(other than cash) of a Person other than the Successor Person, then such other Person will also execute such supplemental indenture and such supplemental indenture will contain such additional provisions, if any, that the Company reasonably
determines are appropriate to preserve the economic interests of the Holders. 
 (B) Notice of Common Stock Change Events. The Company
will provide notice of each Common Stock Change Event to Holders, the Trustee and the Conversion Agent no later than the effective date of such Common Stock Change Event. 

(C) Compliance Covenant. The Company will not become a party to any Common Stock Change Event unless its terms are consistent with this
Section 5.08. 
 Section 5.09. RESTRICTION ON CONVERSIONS. 

(A) Generally. Notwithstanding anything to the contrary in the Indenture or the Notes, no shares of Common Stock will be issued or
delivered upon conversion of any Note, and no Note will be convertible by the Holder thereof, in each case to the extent, and only to the extent, that such issuance, delivery, conversion or convertibility would result in such Holder or a
“person” or “group” (within the meaning of Section 13(d)(3) of the Exchange Act) beneficially owning in excess of 9.99% of the then-outstanding shares of Common Stock (the restrictions set forth in this sentence, the
“Ownership Limitation”). For these purposes, beneficial ownership and calculations of percentage ownership will be determined in accordance with Rule 13d-3 under the Exchange Act. For the
avoidance of doubt, nothing in this Section 5.09(A) will affect the Company’s ability to elect any Settlement Method in accordance with this Supplemental Indenture. 

  
 - 52 - 

 (B) Requirement to Deliver Conversion Consideration Not Extinguished. If any
Conversion Consideration otherwise due upon the conversion of any Note is not delivered as a result of the Ownership Limitation, then the Company’s obligation to deliver such Conversion Consideration will not be extinguished, and the Company
will deliver such Conversion Consideration as soon as reasonably practicable after the Holder of such Note provides written confirmation to the Company that such delivery will not contravene the Ownership Limitation. Any purported delivery of shares
of Common Stock upon conversion of any Note will be void and have no effect to the extent, and only to the extent, that such delivery would contravene the Ownership Limitation. 

Article 6. SUCCESSORS 

Section 6.01. WHEN THE COMPANY MAY MERGE, ETC. 

(A) Generally. The Company will not consolidate with or merge with or into, or (directly, or indirectly through one or more of its
Subsidiaries) sell, lease or otherwise transfer, in one transaction or a series of transactions, all or substantially all of the assets of the Company and its Subsidiaries, taken as a whole, to another Person (a “Business Combination
Event”), unless: 
 (i) the resulting, surviving or transferee Person either (x) is the Company or (y) if
not the Company, is a corporation (the “Successor Corporation”) duly organized and existing under the laws of the United States of America, any State thereof or the District of Columbia that expressly assumes (by executing and
delivering to the Trustee, at or before the effective time of such Business Combination Event, a supplemental indenture pursuant to Section 8.01(E)) all of the Company’s obligations under the Indenture and the Notes;
and 
 (ii) immediately after giving effect to such Business Combination Event, no Default or Event of Default will have
occurred and be continuing. 
 (B) Delivery of Officer’s Certificate and Opinion of Counsel to the Trustee. Before the effective
time of any Business Combination Event, the Company will deliver to the Trustee an Officer’s Certificate and Opinion of Counsel, each stating that (i) such Business Combination Event (and, if applicable, the related supplemental indenture)
comply with Section 6.01(A); and (ii) all conditions precedent to such Business Combination Event provided in the Indenture have been satisfied. 

Section 6.02. SUCCESSOR CORPORATION SUBSTITUTED. 

At the effective time of any Business Combination Event that complies with Section 6.01, the Successor Corporation
(if not the Company) will succeed to, and may exercise every right and power of, the Company under the Indenture and the Notes with the same effect as if such Successor Corporation had been named as the Company in the Indenture and the Notes, and,
except in the case of a lease, the predecessor Company will be discharged from its obligations with respect to the Note under the Indenture and the Notes.

 Article 7. DEFAULTS AND REMEDIES 

Section 7.01. EVENTS OF DEFAULT. 

(A) Definition of Events of Default. “Event of Default” means the occurrence of any of the following: 

(i) a default in the payment when due (whether at maturity, upon Repurchase Upon Fundamental Change or otherwise) of the
principal of, or the Fundamental Change Repurchase Price for, any Note; 
 (ii) a default for thirty (30) days in the
payment when due of interest on any Note; 
 (iii) the Company’s failure to deliver, when required by the Indenture, a
Fundamental Change Notice, or a notice pursuant to Section 5.01(C)(i)(3); 
 (iv) a default in the
Company’s obligation to convert a Note in accordance with Article 5 upon the exercise of the conversion right with respect thereto, if such default is not cured within five (5) Trading Days after its occurrence; 

(v) a default in the Company’s obligations under Article 6; 

(vi) a default in any of the Company’s obligations or agreements under the Indenture or the Notes (other than a default
set forth in clause (i), (ii), (iii), (iv) or (v) of this Section 7.01(A)) where such default is not cured or waived within sixty (60) days after notice to the Company by
the Trustee, or to the Company and the Trustee by Holders of at least twenty five percent (25%) of the aggregate principal amount of Notes then outstanding, which notice must specify such default, demand that it be remedied and state that such
notice is a “Notice of Default”; 
 (vii) a default by the Company or any of its Subsidiaries with respect to any
one or more mortgages, agreements or other instruments under which there is outstanding, or by which there is secured or evidenced, any indebtedness for money borrowed of at least fifty million dollars ($50,000,000) (or its foreign currency
equivalent) in the aggregate of the Company or any of its Subsidiaries, whether such indebtedness exists as of the Issue Date or is thereafter created, where such default: 

(1) constitutes a failure to pay the principal of, or premium or interest on, any of such indebtedness when due and payable at
its stated maturity, upon required repurchase, upon declaration of acceleration or otherwise; or 
 (2) results in such
indebtedness becoming or being declared due and payable before its stated maturity; 

  
 - 54 - 

 (viii) one or more final and
non-appealable judgments being rendered against the Company or any of its Subsidiaries for the payment of at least fifty million dollars ($50,000,000) (or its foreign currency equivalent) in the aggregate
(excluding any amounts covered by bond or insurance), where such judgment is not paid, discharged or stayed within sixty (60) days after (i) the date on which the right to appeal the same has expired, if no such appeal has commenced; or
(ii) the date on which all rights to appeal have been extinguished; 
 (ix) the Company or any of its Significant
Subsidiaries, pursuant to or within the meaning of any Bankruptcy Law, either: 
 (1) commences a voluntary case or
proceeding; 
 (2) consents to the entry of an order for relief against it in an involuntary case or proceeding; 

(3) consents to the appointment of a custodian of it or for any substantial part of its property; 

(4) makes a general assignment for the benefit of its creditors; 

(5) takes any comparable action under any foreign Bankruptcy Law; or 

(6) generally is not paying its debts as they become due; or 

(x) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that either: 

(1) is for relief against Company or any of its Significant Subsidiaries in an involuntary case or proceeding; 

(2) appoints a custodian of the Company or any of its Significant Subsidiaries, or for any substantial part of the property of
the Company or any of its Significant Subsidiaries; 
 (3) orders the winding up or liquidation of the Company or any of its

 (4) grants any similar relief under any foreign Bankruptcy Law, 

and, in each case under this Section 7.01(A)(x), such order or decree remains unstayed and in effect for at least
sixty (60) days. 
 (B) Cause Irrelevant. Each of the events set forth in Section 7.01(A) will
constitute an Event of Default regardless of the cause thereof or whether voluntary or involuntary or 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. 

  
 - 55 - 

 Section 7.02. ACCELERATION. 

(A) Automatic Acceleration in Certain Circumstances. If an Event of Default set forth in Section 7.01(A)(ix)
or 7.01(A)(x) occurs with respect to the Company (and not solely with respect to a Significant Subsidiary of the Company), then the principal amount of, and all accrued and unpaid interest on, all of the Notes then outstanding will
immediately become due and payable without any further action or notice by any Person. 
 (B) Optional Acceleration. Subject to
Section 7.03, if an Event of Default (other than an Event of Default set forth in Section 7.01(A)(ix) or 7.01(A)(x) with respect to the Company and not solely with respect to a Significant
Subsidiary of the Company) occurs and is continuing, then the Trustee, by notice to the Company, or Holders of at least twenty five percent (25%) of the aggregate principal amount of Notes then outstanding, by notice to the Company and the Trustee,
may declare the principal amount of, and all accrued and unpaid interest on, all of the Notes then outstanding to become due and payable immediately. 

(C) Rescission of Acceleration. Notwithstanding anything to the contrary in the Indenture or the Notes, the Holders of a majority in
aggregate principal amount of the Notes then outstanding, by notice to the Company and the Trustee, may, on behalf of all Holders, rescind any acceleration of the Notes and its consequences if (i) such rescission would not conflict with any
judgment or decree of a court of competent jurisdiction; and (ii) all existing Events of Default (except the non-payment of principal of, or interest on, the Notes that has become due solely because of
such acceleration) have been cured or waived. No such rescission will affect any subsequent Default or impair any right consequent thereto. 

Section 7.03. SOLE REMEDY FOR A FAILURE TO
REPORT. 
 (A) Generally. Notwithstanding anything to the contrary in the Indenture or the Notes, the Company may
elect that the sole remedy for any Event of Default (a “Reporting Event of Default”) pursuant to Section 7.01(A)(vi) arising from the Company’s failure to comply with
Section 3.02 (including Section 314(a)(1) of the Trust Indenture Act) will, for each of the first one hundred and eighty (180) calendar days on which a Reporting Event of Default has occurred and is continuing,
consist exclusively of the accrual of Special Interest on the Notes. If the Company has made such an election, then (i) the Notes will be subject to acceleration pursuant to Section 7.02 on account of the relevant
Reporting Event of Default from, and including, the one hundred and eighty first (181st) calendar day on which a Reporting Event of Default has occurred and is continuing or if the Company fails to pay any accrued and unpaid Special Interest when
due; and (ii) Special Interest will cease to accrue on any Notes from, and including, such one hundred and eighty first (181st) calendar day (it being understood that interest on any defaulted Special Interest will nonetheless accrue pursuant
to Section 2.05(B)). 
 (B) Amount and Payment of Special Interest. Any Special Interest that accrues on a
Note pursuant to Section 7.03(A) will be payable on the same dates and in the same manner as the Stated Interest on such Note and will accrue at a rate per annum equal to one quarter of one percent (0.25%) of the principal
amount thereof for the first ninety (90) days on which Special Interest accrues and, thereafter, at a rate per annum equal to one half of one percent (0.50%) of the principal amount thereof. For the avoidance of doubt, any Special Interest that
accrues on a Note will be in addition to the Stated Interest that accrues on such Note. 

  
 - 56 - 

 (C) Notice of Election. To make the election set forth in
Section 7.03(A), the Company must send to the Holders, the Trustee and the Paying Agent, on or before the date on which each Reporting Event of Default first occurs, a notice that (i) briefly describes the report(s)
that the Company failed to file with the SEC; (ii) states that the Company is electing that the sole remedy for such Reporting Event of Default consist of the accrual of Special Interest; and (iii) briefly describes the periods during
which and rate at which Special Interest will accrue and the circumstances under which the Notes will be subject to acceleration on account of such Reporting Event of Default. 

(D) Notice to Trustee and Paying Agent; Trustee’s Disclaimer. If Special Interest accrues on any Note, then, no later than five
(5) Business Days before each date on which such Special Interest is to be paid, the Company will deliver an Officer’s Certificate to the Trustee and the Paying Agent stating (i) that the Company is obligated to pay Special Interest
on such Note on such date of payment; and (ii) the amount of such Special Interest that is payable on such date of payment. The Trustee will have no duty to determine whether any Special Interest is payable or the amount thereof. 

(E) No Effect on Other Events of Default. No election pursuant to this Section 7.03 with respect to a
Reporting Event of Default will affect the rights of any Holder with respect to any other Event of Default, including with respect to any other Reporting Event of Default. 

Section 7.04. OTHER REMEDIES. 

(A) Trustee May Pursue All Remedies. If an Event of Default occurs and is continuing, then the Trustee may pursue any available remedy
to collect the payment of any amounts due with respect to the Notes or to enforce the performance of any provision of the Indenture or the Notes. 

(B) Procedural Matters. The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of
them in such proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy following an Event of Default will not impair the right or remedy or constitute a waiver of, or acquiescence in, such Event of Default. All
remedies will be cumulative to the extent permitted by law. 
 Section 7.05. WAIVER OF PAST
DEFAULTS. 
 An Event of Default pursuant to clause (i), (ii), (iv) or (vi) of
Section 7.01(A) (that, in the case of clause (vi) only, results from a Default under any covenant that cannot be amended without the consent of each affected Holder), and a Default that could lead to such an
Event of Default, can be waived only with the consent of each affected Holder. Each other Default or Event of Default may be waived, on behalf of all Holders, by the Holders of a majority in aggregate principal amount of the Notes then outstanding.
If an Event of Default is so waived, then it will cease to exist. If a Default is so waived, then it will be deemed to be cured and any Event of Default arising therefrom will be deemed not to occur. However, no such waiver will extend to any
subsequent or other Default or Event of Default or impair any right arising therefrom. 

  
 - 57 - 

 Section 7.06. CONTROL BY MAJORITY. 

Holders of a majority in aggregate principal amount of the Notes then outstanding may direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law, the Indenture or the Notes, or that, subject to
Section 7.1 of the Base Indenture, the Trustee determines may be unduly prejudicial to the rights of other Holders or may involve the Trustee in liability, unless the Trustee is offered security and indemnity satisfactory to the Trustee against
any loss, liability or expense to the Trustee that may result from the Trustee’s following such direction. 
 Section 7.07.
LIMITATION ON SUITS. 
 No Holder may pursue any remedy with respect to the Indenture or the
Notes (except to enforce (x) its rights to receive the principal of, or the Fundamental Change Repurchase Price for, or interest on, any Notes; or (y) the Company’s obligations to convert any Notes pursuant to Article 5),
unless: 
 (A) such Holder has previously delivered to the Trustee notice that an Event of Default is continuing; 

(B) Holders of at least twenty five percent (25%) in aggregate principal amount of the Notes then outstanding deliver a request to the Trustee
to pursue such remedy; 
 (C) such Holder or Holders offer and, if requested, provide to the Trustee security and indemnity satisfactory to
the Trustee against any loss, liability or expense to the Trustee that may result from the Trustee’s following such request; 
 (D) the
Trustee does not comply with such request within sixty (60) calendar days after its receipt of such request and such offer of security or indemnity; and 

(E) during such sixty (60) calendar day period, Holders of a majority in aggregate principal amount of the Notes then outstanding do not
deliver to the Trustee a direction that is inconsistent with such request. 
 A Holder of a Note may not use the Indenture to prejudice the
rights of another Holder or to obtain a preference or priority over another Holder. The Trustee will have no duty to determine whether any Holder’s use of the Indenture complies with the preceding sentence. 

Section 7.08. ABSOLUTE RIGHT OF HOLDERS TO RECEIVE
PAYMENT AND CONVERSION CONSIDERATION AND TO INSTITUTE SUIT FOR THE ENFORCEMENT
OF SUCH RIGHT. 
 Notwithstanding anything to the contrary in the Indenture or the Notes
(but without limiting Section 8.01), the right of each Holder of a Note to receive payment or delivery, as applicable, of the principal of, or the Fundamental Change Repurchase Price for, or any interest on, or the
Conversion Consideration due pursuant to Article 5 upon conversion of, such Note on or after the respective due dates therefor provided in the Indenture and the Notes, or to bring suit for the enforcement of any such payment or delivery after
such respective due dates, will not be impaired or affected without the consent of such Holder. 

  
 - 58 - 

 Section 7.09. COLLECTION SUIT BY
TRUSTEE. 
 The Trustee will have the right, upon the occurrence and continuance of an Event of Default pursuant to
clause (i), (ii) or (iv) of Section 7.01(A), to recover judgment in its own name and as trustee of an express trust against the Company for the total unpaid or undelivered principal of, or
Fundamental Change Repurchase Price for, or interest on, or Conversion Consideration due pursuant to Article 5 upon conversion of, the Notes, as applicable, and, to the extent lawful, any Default Interest on any Defaulted Amounts, and such
further amounts sufficient to cover the costs and expenses of collection, including compensation provided for in Section 7.7 of the Base Indenture. 

Section 7.10. TRUSTEE MAY FILE PROOFS OF CLAIM. 

The Trustee has the right to (A) file such proofs of claim and other papers or documents as may be necessary or advisable in order to have
the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes) or its creditors or property and (B) collect, receive and distribute any money or other property payable
or deliverable on any such claims. Each Holder authorizes any custodian in such proceeding to make such payments to the Trustee, and, if the Trustee consents to the making of such payments directly to the Holders, to pay to the Trustee any amount
due to the Trustee for the reasonable compensation, expenses, disbursements and advances of the Trustee, and its agents and counsel, and any other amounts payable to the Trustee pursuant to Section 7.7 of the Base Indenture. To the extent that
the payment of any such compensation, expenses, disbursements, advances and other amounts out of the estate in such proceeding, is denied for any reason, payment of the same will be secured by a lien on, and will be paid out of, any and all
distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding (whether in liquidation or under any plan of reorganization or arrangement or otherwise). Nothing in the Indenture will
be deemed to authorize the Trustee to authorize, consent to, accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding. 
 Section 7.11. PRIORITIES. 

The Trustee will pay or deliver in the following order any money or other property that it collects pursuant to this Article 7: 

First: to the Trustee and its agents and attorneys for amounts due under Section 7.7 of the Base Indenture,
including payment of all fees, compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 

  
 - 59 - 

 Second: to Holders for unpaid amounts or other property due on the
Notes, including the principal of, or the Fundamental Change Repurchase Price for, or any interest on, or any Conversion Consideration due upon conversion of, the Notes, ratably, and without preference or priority of any kind, according to such
amounts or other property due and payable on all of the Notes; and 
 Third: to the Company or such other Person as a
court of competent jurisdiction directs. 
 The Trustee may fix a record date and payment date for any payment or delivery to the Holders
pursuant to this Section 7.11, in which case the Trustee will instruct the Company to, and the Company will, deliver, at least fifteen (15) calendar days before such record date, to each Holder and the Trustee a notice
stating such record date, such payment date and the amount of such payment or nature of such delivery, as applicable. 
 Section 7.12.
UNDERTAKING FOR COSTS. 
 In any suit for the enforcement of any right or remedy under the
Indenture or the Notes or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court, in its discretion, may (A) require the filing by any litigant party in such suit of an undertaking to pay the costs of such
suit, and (B) assess reasonable costs (including reasonable attorneys’ fees) against any litigant party in such suit, having due regard to the merits and good faith of the claims or defenses made by such litigant party; provided,
however, that this Section 7.12 does not apply to any suit by the Trustee, any suit by a Holder pursuant to Section 7.08 or any suit by one or more Holders of more than ten percent (10%) in
aggregate principal amount of the Notes then outstanding. 
 Section 7.13. TRUSTEE’S OBLIGATION
TO PROVIDE NOTICE OF DEFAULTS TO HOLDERS. 

If a Default or Event of Default occurs and is continuing and is known to the Trustee, then the Trustee will send Holders a notice of such
Default or Event of Default within ninety (90) days after it occurs or, if it is not known to the Trustee at such time, promptly (and in any event within ten (10) Business Days) after it becomes known to a Responsible Officer;
provided, however, that, except in the case of a Default or Event of Default in the payment of the principal of, or interest on, any Note, the Trustee may withhold such notice if and for so long as it in good faith determines that
withholding such notice is in the interests of the Holders. 
 Article 8. AMENDMENTS, SUPPLEMENTS AND WAIVERS 

Section 8.01. WITHOUT THE CONSENT OF HOLDERS. 

Notwithstanding anything to the contrary in Section 8.02, the Company and the Trustee may amend or supplement the
Indenture or the Notes without the consent of any Holder to: 
 (A) cure any ambiguity or correct any omission, defect or inconsistency in
the Indenture or the Notes; 
 (B) add guarantees with respect to the Company’s obligations under the Indenture or the Notes;

 (F) enter into supplemental indentures pursuant to, and in accordance with,

changes to the extent expressly required by this Supplemental Indenture; 
 (G) irrevocably elect or eliminate any Settlement Method or
Specified Dollar Amount; provided, however, that no such election or elimination will affect any Settlement Method theretofore elected (or deemed to be elected) with respect to any Note pursuant to
Section 5.03(A); 
 (H) evidence or provide for the acceptance of the appointment, under the Indenture, of a
successor Trustee; 
 (I) conform the provisions of the Indenture and the Notes to the “Description of Notes” section of the
Company’s preliminary prospectus supplement, dated May 6, 2020, as supplemented by the related pricing term sheet, dated May 7, 2020; 

(J) provide for or confirm the issuance of additional Notes pursuant to Section 2.03(B); 

(K) comply with any requirement of the SEC in connection with effecting or maintaining the qualification of the Indenture, or any supplemental
indenture thereto, under the Trust Indenture Act, as then in effect; 
 (L) provide for any transfer restrictions that apply to any Notes
issued under the Indenture (other than the Initial Notes) that, at the time of their original issuance, constitute “restricted securities” within the meaning of Rule 144 under the Securities Act or that are originally issued in reliance
upon Regulation S under the Securities Act; or 
 (M) make any other change to the Indenture or the Notes that does not, individually or in
the aggregate with all other such changes, adversely affect the rights of the Holders, as such, in any material respect. 
 At the written
request of any Holder of a Note or owner of a beneficial interest in a Global Note, the Company will provide a copy of the “Description of Notes” section and pricing term sheet referred to in Section 8.01(I). 

  
 - 61 - 

 Section 8.02. WITH THE CONSENT OF
HOLDERS. 
 (A) Generally. Subject to Sections 8.01, 7.05 and 7.08 and the immediately
following sentence, the Company and the Trustee may, with the consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding, amend or supplement the Indenture or the Notes or waive compliance with any provision of
the Indenture or the Notes. Notwithstanding anything to the contrary in the foregoing sentence, but subject to Section 8.01, without the consent of each affected Holder, no amendment or supplement to the Indenture or the
Notes, or waiver of any provision of the Indenture or the Notes, may: 
 (i) reduce the principal, or extend the stated
maturity, of any Note; 
 (ii) reduce the Fundamental Change Repurchase Price for any Note or change the times at which, or
the circumstances under which, the Notes will be repurchased by the Company; 
 (iii) reduce the rate, or extend the time for
the payment, of interest on any Note; 
 (iv) make any change that adversely affects the conversion rights of any Note; 

(v) impair the rights of any Holder set forth in Section 7.08 (as such section is in effect on the
Issue Date); 
 (vi) change the ranking of the Notes; 

(vii) make any Note payable in money, or at a place of payment, other than that stated in the Indenture or the Note; 

(viii) reduce the amount of Notes whose Holders must consent to any amendment, supplement, waiver or other modification; or

 (ix) make any direct or indirect change to any amendment, supplement, waiver or modification provision of the Indenture or
the Notes that requires the consent of each affected Holder. 
 For the avoidance of doubt, pursuant to clauses (i),
(ii), (iii) and (iv) of this Section 8.02(A), no amendment or supplement to the Indenture or the Notes, or waiver of any provision of the Indenture or the Notes, may change the amount or type of
consideration due on any Note (whether on an Interest Payment Date, Fundamental Change Repurchase Date or the Maturity Date or upon conversion, or otherwise), or the date(s) or time(s) such consideration is payable or deliverable, as applicable,
without the consent of each affected Holder. 
 (B) Holders Need Not Approve the Particular Form of any Amendment. A consent of any
Holder pursuant to this Section 8.02 need approve only the substance, and not necessarily the particular form, of the proposed amendment, supplement or waiver. 

  
 - 62 - 

 Section 8.03. NOTICE OF AMENDMENTS,
SUPPLEMENTS AND WAIVERS. 
 As soon as reasonably practicable after any amendment,
supplement or waiver pursuant to Section 8.01 or 8.02 becomes effective, the Company will send to the Holders and the Trustee notice that (A) describes the substance of such amendment, supplement or waiver in
reasonable detail and (B) states the effective date thereof; provided, however, that the Company will not be required to provide such notice to the Holders if such amendment, supplement or waiver is included in a periodic report
filed by the Company with the SEC within four (4) Business Days of its effectiveness. The failure to send, or the existence of any defect in, such notice will not impair or affect the validity of such amendment, supplement or waiver. 

Section 8.04. REVOCATION, EFFECT AND SOLICITATION OF
CONSENTS; SPECIAL RECORD DATES; ETC. 
 (A) Revocation and
Effect of Consents. The consent of a Holder of a Note to an amendment, supplement or waiver will bind (and constitute the consent of) each subsequent Holder of any Note to the extent the same evidences any portion of the same indebtedness as the
consenting Holder’s Note, subject to the right of any Holder of a Note to revoke (if not prohibited pursuant to Section 8.04(B)) any such consent with respect to such Note by delivering notice of revocation to the
Trustee before the time such amendment, supplement or waiver becomes effective. 
 (B) Special Record Dates. The Company may, but is
not required to, fix a record date for the purpose of determining the Holders entitled to consent or take any other action in connection with any amendment, supplement or waiver pursuant to this Article 8. If a record date is fixed, then,
notwithstanding anything to the contrary in Section 8.04(A), only Persons who are Holders as of such record date (or their duly designated proxies) will be entitled to give such consent, to revoke any consent previously
given or to take any such action, regardless of whether such Persons continue to be Holders after such record date; provided, however, that no such consent will be valid or effective for more than one hundred and twenty
(120) calendar days after such record date. 
 (C) Solicitation of Consents. For the avoidance of doubt, each reference in the
Indenture or the Notes to the consent of a Holder will be deemed to include any such consent obtained in connection with a repurchase of, or tender or exchange offer for, any Notes. 

(D) Effectiveness and Binding Effect. Each amendment, supplement or waiver pursuant to this Article 8 will become effective in
accordance with its terms and, when it becomes effective with respect to any Note (or any portion thereof), will thereafter bind every Holder of such Note (or such portion). 

Section 8.05. NOTATIONS AND EXCHANGES. 

If any amendment, supplement or waiver changes the terms of a Note, then the Trustee or the Company may, in its discretion, require the Holder
of such Note to deliver such Note to the Trustee so that the Trustee may place an appropriate notation prepared by the Company on such Note and return such Note to such Holder. Alternatively, at its discretion, the Company may, in exchange for such
Note, issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, a new Note that reflects the changed terms. The failure to make any appropriate notation or issue a new Note
pursuant to this Section 8.05 will not impair or affect the validity of such amendment, supplement or waiver. 

  
 - 63 - 

 Section 8.06. TRUSTEE TO EXECUTE
SUPPLEMENTAL INDENTURES. 
 The Trustee will execute and deliver any amendment or supplemental indenture
authorized pursuant to this Article 8; provided, however, that the Trustee need not (but may, in its sole and absolute discretion) execute or deliver any such amendment or supplemental indenture that adversely affects the
Trustee’s rights, duties, liabilities or immunities. In executing any amendment or supplemental indenture, the Trustee will be entitled to receive, and (subject to Sections 7.1 and 7.2 of the Base Indenture) will be fully protected in relying
on, an Officer’s Certificate and an Opinion of Counsel stating that (A) the execution and delivery of such amendment or supplemental indenture is authorized or permitted by the Indenture; and (B) in the case of the Opinion of Counsel,
such amendment or supplemental indenture is valid, binding and enforceable against the Company in accordance with its terms. 
 Article 9.
SATISFACTION AND DISCHARGE 
 Section 9.01. TERMINATION OF COMPANY’S
OBLIGATIONS. 
 The Indenture will be discharged, and will cease to be of further effect, as to all Notes issued under the
Indenture, when: 
 (A) all Notes then outstanding (other than Notes replaced pursuant to Section 2.12) have
(i) been delivered to the Trustee for cancellation; or (ii) become due and payable (whether on a Fundamental Change Repurchase Date, the Maturity Date, upon conversion or otherwise) for an amount of cash or Conversion Consideration, as
applicable, that has been fixed; 
 (B) the Company has caused there to be irrevocably deposited with the Trustee, or with the Paying Agent
(or, with respect to Conversion Consideration, the Conversion Agent), in each case for the benefit of the Holders, or has otherwise caused there to be delivered to the Holders, cash (or, with respect to Notes to be converted, Conversion
Consideration) sufficient to satisfy all amounts or other property due on all Notes then outstanding (other than Notes replaced pursuant to Section 2.12); 

(C) the Company has paid all other amounts payable by it under the Indenture with respect to the Notes; and 

(D) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that the conditions
precedent to the discharge of the Indenture with respect to the Notes have been satisfied; 
 provided, however, that Article VII of the Base
Indenture and Section 10.01 will survive such discharge and, until no Notes remain outstanding, Section 2.14 and the obligations of the Trustee, the Paying Agent and the Conversion Agent with
respect to money or other property deposited with them will survive such discharge. 
 At the Company’s request, the Trustee will
acknowledge the satisfaction and discharge of the Indenture as to the Notes. 

  
 - 64 - 

 Section 9.02. REPAYMENT TO COMPANY. 

Subject to applicable unclaimed property law, the Trustee, the Paying Agent and the Conversion Agent will promptly notify the Company if there
exists (and, at the Company’s request, promptly deliver to the Company) any cash, Conversion Consideration or other property held by any of them for payment or delivery on the Notes that remain unclaimed two (2) years after the date on
which such payment or delivery was due. After such delivery to the Company, the Trustee, the Paying Agent and the Conversion Agent will have no further liability to any Holder with respect to such cash, Conversion Consideration or other property,
and Holders entitled to the payment or delivery of such cash, Conversion Consideration or other property must look to the Company for payment as a general creditor of the Company. 

Section 9.03. REINSTATEMENT. 

If the Trustee, the Paying Agent or the Conversion Agent is unable to apply any cash or other property deposited with it pursuant to
Section 9.01 because of any legal proceeding or any order or judgment of any court or other governmental authority that enjoins, restrains or otherwise prohibits such application, then the discharge of the Indenture
pursuant to Section 9.01 will be rescinded; provided, however, that if the Company thereafter pays or delivers any cash or other property due on the Notes to the Holders thereof, then the Company will be
subrogated to the rights of such Holders to receive such cash or other property from the cash or other property, if any, held by the Trustee, the Paying Agent or the Conversion Agent, as applicable.

facsimile, electronic transmission or other similar means of unsecured electronic communication; and (D) the next Business Day after timely delivery to the courier, if sent by overnight air courier guaranteeing next day delivery. 

All notices or communications required to be made to a Holder pursuant to the Indenture must be made in writing and will be deemed to be duly
sent or given in writing if mailed by first class mail, certified or registered, return receipt requested, or by overnight air courier guaranteeing next day delivery, to its address shown on the Register; provided, however, that a
notice or communication to a Holder of a Global Note may, but need not, instead be sent pursuant to the Depositary Procedures (in which case, such notice will be deemed to be duly sent or given in writing). The failure to send a notice or
communication to a Holder, or any defect in such notice or communication, will not affect its sufficiency with respect to any other Holder. 

If the Trustee is then acting as the Depositary’s custodian for the Notes, then, at the reasonable request of the Company to the Trustee,
the Trustee will cause any notice prepared by the Company to be sent to any Holder(s) pursuant to the Depositary Procedures, provided such request is evidenced in a Company Order delivered, together with the text of such notice, to the
Trustee at least two (2) Business Days before the date such notice is to be so sent. For the avoidance of doubt, such Company Order need not be accompanied by an Officer’s Certificate or Opinion of Counsel. The Trustee will not have any
liability relating to the contents of any notice that it sends to any Holder pursuant to any such Company Order. 
 If a notice or
communication is mailed or sent in the manner provided above within the time prescribed, it will be deemed to have been duly given, whether or not the addressee receives it. 

Notwithstanding anything to the contrary in the Indenture or the Notes, (A) whenever any provision of the Indenture requires a party to
send notice to another party, no such notice need be sent if the sending party and the recipient are the same Person acting in different capacities; and (B) whenever any provision of the Indenture requires a party to send notice to more than
one receiving party, and each receiving party is the same Person acting in different capacities, then only one such notice need be sent to such Person.

beneficial owner, then the Company or such withholding agent, as applicable, may make such withholding by deducting from, or may set off such payments against, any payment on any Note or any Common Stock of such Holder or beneficial owner, or any
