on which such interest, if any, shall commence and be payable and any regular record date for the interest payable on any interest payment date; 

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

provisions or at the option of a Holder thereof and the period or periods within which, the price or prices at which and the terms and conditions upon which Securities of the Series shall be redeemed or purchased, in whole or in part, pursuant
to such obligation; 
 (i) the dates, if any, on which and the price or prices at which the Securities of the Series will be repurchased

(p) the provisions, if any, relating to conversion of any Securities of such Series, including, if applicable, the securities into which the

(s) any other terms of the Securities of the Series (which may modify or delete any provision of this Indenture insofar as it applies to
such Series). 
 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 Officers’ Certificate referred to above, and, unless otherwise provided in such Board Resolution, a Series may be
reopened, without the consent of the Holders, for increases in the aggregate principal amount of such Series and issuances of additional Securities of such Series. 

Section 2.03 Execution and Authentication. At least one 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 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 Officers’ Certificate, upon receipt by the Trustee of a Company Order. Such Company Order may authorize authentication and delivery pursuant to electronic
instructions in PDF from the Company or its duly authorized agent or agents. Each Security shall be dated the date of its authentication unless otherwise provided by a Board Resolution, a supplemental indenture hereto or an Officers’
Certificate. The aggregate principal amount of Securities of any 

  
 -8- 

 
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
Officers’ Certificate delivered pursuant to Section 2.02, except as provided in Section 2.02 or 2.08. Prior to the issuance of Securities of any Series, the Trustee shall have received and (subject to Section 7.02) shall be fully
protected in relying on: (a) the Board Resolution, supplemental indenture hereto or Officers’ 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 Officers’ Certificate complying with Section 10.04 and (c)(1) an Opinion of Counsel complying with Section 10.04 or (2) an Opinion of Counsel (or reliance
letter with respect to an Opinion of Counsel) that the Securities have been duly authorized, executed and delivered by the Company and such Securities will constitute valid and binding obligations of the Company, enforceable against the Company in
accordance with its terms. 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. 

Section 2.04 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 2.02, an office or agency where Securities of such Series may be presented or surrendered for payment (“Paying Agent”), and where Securities of
such Series may be surrendered for registration of transfer or exchange (“Registrar”). The Registrar shall keep a register with respect to each Series of Securities and of their transfer and exchange. The Company hereby
appoints the Trustee as Paying Agent and Registrar. 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 or Paying Agent. The Company may also from time to time
designate one or more co-registrars or additional paying 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 and a Paying Agent in each place so specified pursuant to Section 2.02 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 or additional paying agent. The term “Registrar” includes any co-registrar; and the term “Paying Agent” includes any additional paying agent. The Company hereby appoints the
Trustee as the initial Registrar and Paying Agent for each Series unless another Registrar or Paying Agent, as the case may be, is appointed prior to the time Securities of that Series are first issued. 

Section 2.05 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 Holders 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 of any default by the Company in making any such payment. While any such default continues, the Trustee may require a 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 

  
 -9- 

 
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 Holders of any
Series of Securities all money held by it as Paying Agent. Upon an Event of Default under Section 6.01(d) or (e), the Trustee shall be the Paying Agent. 

Section 2.06 Holder 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 Holders of each Series of Securities and shall otherwise comply with TIA Section 312(a). If the Trustee is not the Registrar, the Company shall furnish to the Trustee at least ten (10) 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 Holders of each Series of Securities. 

Section 2.07 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, 3.06 or 9.06). 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 delivery 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 delivery, 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. 

Section 2.08 Mutilated, Destroyed, Lost and Stolen Securities. 

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

  
 -10- 

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

Section 2.09 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 2.08, it ceases to be outstanding until the Trustee receives proof satisfactory to it that the replaced Security is held by a protected 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. 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 6.02. 

Section 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 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. 

Section 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 request 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. 

  
 -11- 

 Section 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 registration of transfer,
exchange, payment, replacement or cancellation in accordance with its customary procedures. The Company may not issue new Securities to replace Securities that it has paid or delivered to the Trustee for cancellation. 

Section 2.13 Defaulted Interest. If the Company defaults in a payment of interest on a Series of Securities, it shall pay the
defaulted interest at the rate established for the particular Series, if any, plus, to the extent permitted by law, any interest payable on the defaulted interest, to the persons who are Holders of the Series on a subsequent special record
date. The Company shall fix the special record date and payment date; provided that if no rate for defaulted interest is specified for any Series of Securities, then the defaulted interest rate shall be the interest rate specified for such Series of
Securities. At least ten (10) days before the special record date, the Company shall deliver to the Trustee and to each Holder of the Series a notice that states the record date, the related payment date and the amount of interest to be
paid. The Company may also pay defaulted interest in any other lawful manner. 
 Section 2.14 Global Securities 

(a) Terms of Securities. A Board Resolution, a supplemental indenture hereto or an Officers’ 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. 

(b) Transfer and Exchange. Notwithstanding any provisions to the contrary contained in Section 2.07 of the Indenture and in addition
thereto, any Global Security shall be exchangeable pursuant to Section 2.07 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, (ii) the Company executes and delivers to the Trustee an Officers’ Certificate to the effect that such Global Security shall be so
exchangeable or (iii) an Event of Default with respect to the Securities represented by such Global Security shall have happened and be continuing. 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. 

  
 -12- 

 (c) Except as provided in this Section 2.14(c), 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. 
 (d) 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.” 
 (e) 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. 

(f) Payments. Notwithstanding the other provisions of this Indenture, unless otherwise specified as contemplated by Section 2.02, payment
of the principal of and interest, if any, on any Global Security shall be made to the Holder thereof. 
 (g) Consents, Declaration and
Directions. Except as provided in Section 2.14(g), 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 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. 

(h) The Depositary or its nominee, as registered owner of a Global Security, shall be the Holder of such Global Security for all purposes under
the Indenture and the Securities, and owners of beneficial interests in a Global Security shall hold such interests pursuant to the Applicable Procedures. Accordingly, any such owner’s beneficial interest in a Global Security will be shown only
on, and the transfer of such interest shall be effected only through, records maintained by the Depositary or its nominee and such owners of beneficial interests in a Global Security will not be considered the owners or holders thereof.
Notwithstanding any other provision of this Indenture or any Security, where this Indenture or any Global Security provides for notice of any event (including any notice of redemption or repurchase) to a Holder of a Global Security (whether by mail
or otherwise), such notice shall be sufficiently given if given to the Depositary (or its designee) pursuant to the standing instructions from the Depositary or its designee, including by electronic mail in accordance with applicable Depositary
procedures. 

  
 -13- 

 Section 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. The Company shall promptly notify the Trustee of any change in “CUSIP” numbers of which the Company becomes aware. 

ARTICLE III 

REDEMPTION 
 Section
3.01 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 of the redemption date and the principal amount of the Series of Securities to be redeemed. 

Section 3.02 Selection of Securities to be Redeemed. Unless otherwise indicated for a particular Series by a Board
Resolution, a supplemental indenture or an Officers’ 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. The Trustee shall make the selection from Securities of the Series outstanding not previously called for redemption. Securities of a Series and portions selected for redemption 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 2.02(j), the minimum principal denomination for each Series and 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. The Trustee shall not be liable for the selection made in accordance with this
Section 3.02. 
 Section 3.03 Notice of Redemption. 

(a) Unless otherwise specified for a particular Series by a Board Resolution, a supplemental indenture or an Officers’ Certificate,
at least 30 days but not more than 60 days before a redemption date, the Company shall deliver notice of redemption to each Holder whose Securities are to be redeemed. The notice shall identify the Securities of the Series to be redeemed and
shall state: 
 (i) the redemption date; 

(ii) the redemption price or the manner of the calculation of the redemption price; 

  
 -14- 

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

(iv) that Securities of the Series called for redemption must be surrendered to the Paying Agent to collect the redemption price;

(vi) the CUSIP number, if any; and 

(vii) 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
that the Company shall have delivered to the Trustee, at least five Business Days (or such shorter period as the Trustee may consent to in writing) before notice of redemption is required to be delivered or caused to be delivered to Holders pursuant
to this Section 3.03, an Officers’ Certificate of the Company requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph. 

Section 3.04 Effect of Notice of Redemption. Once notice of redemption is delivered as provided in Section 3.03, Securities
of a Series called for redemption become due and payable on the redemption date and at the redemption price. 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; provided that installments of interest whose Stated Maturity is on or prior to the redemption date shall be payable to the Holders of such Securities (or one or more predecessor Securities)
registered at the close of business on the relevant record date therefor according to their terms and the terms of this Indenture. 

Section 3.05 Deposit of Redemption Price. Unless otherwise indicated for a particular Series by a Board Resolution, a
supplemental indenture or an Officers’ Certificate, 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. 
 Section 3.06 Securities Redeemed in Part. Upon surrender of a Security
that is redeemed in part, the Company shall issue and 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.

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 that 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. No such rescission shall
affect any subsequent Default or impair any right consequent thereon. 
 Section 6.03 Collection of Indebtedness and Suits for
Enforcement by Trustee. 
 The Company covenants that if: 

(a) default is made in the payment of any interest on any Security 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, 

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.

 Section 6.04 Trustee May File Proofs of Claim. In case of the pendency of any
receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or of such other
obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of overdue principal or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise, (a) to file and prove a claim for the whole amount of principal and 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 7.07. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or
the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 

Section 6.05 Trustee May Enforce Claims Without Possession of Securities. All rights of action and claims under this
Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be
brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered. 
 Section 6.06 Application of
Money Collected. 
 Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or
dates fixed by the Trustee and, in case of the distribution of such money on 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 7.07; 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. 

Section 6.07 Limitation on Suits. No Holder of any Security of any Series shall have any right to institute any proceeding,
judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless: 

(a) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that
Series; 
 (b) the Holders of at least a majority 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 shall have offered to the Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities to be incurred 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 and intended that no one or more of such Holders shall
have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other
of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all such Holders. 

Section 6.08 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 Stated Maturity or Stated Maturities expressed in such Security
(or, in the case of redemption, on the redemption date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder. 

Section 6.09 Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right
or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding,
the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been
instituted. 

  
 -21- 

 Section 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 2.08, 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. 

Section 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. 

Section 6.12 Control by Holders. Subject to Section 7.02(f), the Holders of a majority in principal amount of the outstanding
Securities of any Series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Securities
of such Series, provided that: 
 (a) such direction shall not be in conflict with any rule of law or with this Indenture, 

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

(c) subject to the provisions of Section 7.01, 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. 

Section 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 (i) 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) or (ii) in respect of a covenant or provision hereof which cannot be modified or amended without the consent of the Holder of each outstanding Security of such Series affected. Upon any such waiver, such
Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent
thereon. 

  
 -22- 

 Section 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 Stated Maturity or Stated Maturities expressed in such Security (or, in the case of redemption, on the redemption date). 

ARTICLE VII 

TRUSTEE 
 Section 7.01
Duties of Trustee. 
 (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested

hereunder. 
 Section 7.03 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. 
 Section 7.04 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. 

Section 7.05 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 deliver to each Holder of the Securities of that Series notice of a Default or Event of Default within 90 days after it occurs or, if 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 it in good faith determines that withholding the notice is in the interests of Holders of that Series. 
 Section 7.06
Reports by Trustee to Holders. Within 60 days after March 15 in each year, the Trustee shall transmit by deliver to all Holders, as their names and addresses appear on the register kept by the Registrar a brief report dated as of such

that Series are listed. The Company shall promptly notify the Trustee when Securities of any Series are listed on any stock exchange. 

Section 7.07 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 loss, liability or expense, 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 this Section 7.07 in the
performance of its 

  
 -26- 

 
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 or delay by the Trustee to so notify the
Company of any claim for which it may seek indemnity shall not relieve the Company of its obligations hereunder except to the extent such failure or delay shall have materially prejudiced the Company. 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 shall
not be unreasonably withheld. This indemnification shall apply to officers, directors, employees, shareholders and agents of the Trustee. 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 the gross negligence or willful misconduct of any such persons as determined by a final order of a court of competent jurisdiction. When the Trustee incurs expenses
or renders services after an Event of Default specified in Section 6.01(d) or (e) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any insolvency, bankruptcy or similar
law. The provisions of this Section shall survive the resignation or removal of the Trustee and the termination or discharge of this Indenture. 

Section 7.08 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 bankrupt or insolvent or an order for relief is entered with respect to the Trustee under any insolvency,
bankruptcy or similar 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. 
 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. 

  
 -27- 

 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 7.07, 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 deliver a
notice of its succession to each Holder of each such Series. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company’s obligations under Section 7.07 hereof shall continue for the benefit of the retiring
Trustee with respect to expenses and liabilities incurred by it prior to the date of such replacement. 
 Section 7.09 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 (including administration of this Indenture) to, another corporation, the successor corporation
without any further act shall be the successor Trustee. 
 Section 7.10 Eligibility; Disqualification. This Indenture shall
always have a Trustee who satisfies the requirements of TIA Section 310(a)(1), (2) and (5) and has a combined capital and surplus of at least $50,000,000. The Trustee shall comply with TIA Section 310(b). 

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

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.

Section 8.03 is otherwise specified, pursuant to Section 2.02(s), to be inapplicable to Securities of any Series, the Company shall be deemed to have paid and discharged the entire indebtedness on all the outstanding Securities of any

agreement or instrument to which the Company is a party or by which it is bound; 
 (f) no Default or Event of Default with respect to the
Securities of such Series shall have occurred and be continuing on the date of such deposit or during the period ending on the 91st day after such date; 

  
 -30- 

 (g) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion
of Counsel to the effect that (i) the Company has received from, or there has been published by, the Internal Revenue Service a ruling, or (ii) since the date of execution of this Indenture, there has been a change in the applicable
Federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the 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, defeasance and discharge and will be subject to Federal income tax on the same amounts 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; 

(h) the Company shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company with the

(i) the Company shall have delivered to the Trustee an Officers’ 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; and

 Section 8.04 Covenant Defeasance. Unless this Section 8.04 is otherwise specified, pursuant to Section 2.02(s), to
be inapplicable to Securities of any Series, on and after the 91st day after the date of the deposit referred to in subparagraph (a) hereof, the Company may omit to comply with respect to the Securities of any Series with any term,
provision or condition set forth under Sections 4.02, 4.03, and 5.01 as well as any additional covenants specified in a supplemental indenture for such Series of Securities or a Board Resolution or an Officers’ Certificate delivered
pursuant to Section 2.02 (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 6.01) and the occurrence of any event specified in a supplemental
indenture for such Series of Securities or a Board Resolution or an Officers’ Certificate delivered pursuant to Section 2.02 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 8.04, the Company has deposited or caused to be irrevocably deposited (except as provided in Section 8.02(c)) with the Trustee as trust funds in trust for the purpose of making the following payments specifically pledged as

 -31- 

 
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 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; 
 (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 or during the period ending on the 91st day after such date; 

(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 Officers’
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; and 

(f) Such defeasance shall not result in the trust arising from such deposit constituting an investment company within the meaning of the
Investment Company Act of 1940, as amended, unless such trust shall be registered under such Act or exempt from registration thereunder. 

Section 8.05 Repayment to Company. The Trustee and the Paying Agent shall pay to the Company upon written request any money held
by them for the payment of principal and interest that remains unclaimed for two years, and after such time, Holders entitled to the money must look to the Company for payment as general creditors unless an applicable abandoned property law
designates another person. 
 Section 8.06 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 8.01 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 8.01 until such time as the Trustee or the Paying Agent is permitted to apply all such money in accordance with Section 8.01; provided, however, that if the Company has made any payment of 

  
 -32- 

 
principal of, premium (if any) or interest on 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 the Paying Agent. 
 ARTICLE IX

 AMENDMENTS AND WAIVERS 

Section 9.01 Without Consent of Holders. Unless otherwise specified for a particular Series by a Board Resolution, a supplemental
indenture or an Officers’ Certificate, the Company and the Trustee may amend or supplement this Indenture or the Securities of one or more Series without the consent of any Holder: 

(a) to evidence the succession of another person to the Company under this Indenture and the Securities and the assumption by any such
Successor Person of the obligations of the Company hereunder and under the Securities; 
 (b) to add covenants of the Company for the benefit
of the Holders of all or any series of Securities (and if such covenants are to be for the benefit of less than all series of Securities, stating that such covenants are expressly being included for the benefit of such series) or to surrender any
right or power herein conferred upon the Company provided such action does not adversely affect the interests of the Holders; 
 (c) to add
any additional Events of Default; 
 (d) to add to or change any of the provisions of this Indenture to such extent as shall be necessary to
permit or facilitate the issuance of Securities in bearer form, registrable or not registrable as to principal, and with or without interest coupons, or to permit or facilitate the issuance of Securities in uncertificated form; 

(e) to add to, change or eliminate any of the provisions of this Indenture in respect of one or more series of Securities, provided that any
such addition, change or elimination (A) shall neither (i) apply to any Security of any series created prior to the execution of such supplemental indenture and entitled to the benefit of such provision nor (ii) modify the rights of
the Holder of any such Security with respect to such provision or (B) shall become effective only when there is no such Security Outstanding; 

(f) to establish the forms or terms of the Securities of any series issued pursuant to the terms hereof; 

(g) to cure any ambiguity or correct any inconsistency in this Indenture; 

(h) 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; 

  
 -33- 

 (i) to qualify this Indenture under the Trust Indenture Act; 

(j) to provide for uncertificated securities in addition to certificated securities; 

(k) to supplement any provisions of this Indenture necessary to permit or facilitate the defeasance and discharge of any series of Securities,
provided that such action does not adversely affect the interests of the Holders of Securities of such series or any other series; 
 (l) to
conform the Indenture to any Description of Securities for a particular Series of Securities; and 
 (m) to comply with the rules or
regulations of any securities exchange or automated quotation system on which any of the Securities may be listed or traded. 
 Section
9.02 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 Holders 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. It shall not be necessary for the consent of the Holders of Securities under this Section 9.02 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 deliver to the Holders of Securities affected thereby a notice briefly describing
the supplemental indenture or waiver. Any failure by the Company to deliver such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture or waiver. 

Section 9.03 Limitations. Unless otherwise specified for a particular Series by a Board Resolution, a supplemental indenture or an
Officers’ Certificate, without the consent of each Holder affected, an amendment or waiver may not: 
 (a) reduce the 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; 

  
 -34- 

 (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 6.08, 6.13, or 9.03; or 

(h) waive a redemption payment with respect to any Security. 

Section 9.04 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. 
 Section 9.05
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 Holder 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 9.03. 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. 

Section 9.06 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.

 Section 9.07 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 receive, in addition to the documents required by Section 10.04, and (subject to Section 7.01) shall be fully protected in
relying upon, an Opinion of 

  
 -35- 

 
Counsel stating that all conditions precedent in this Indenture to the execution of such supplemental indenture, if any, have been complied with, such supplemental indenture is authorized
hereunder, and, that such supplemental indenture is the valid and legally binding obligation of the Company. The Trustee shall sign all supplemental indentures, except that the Trustee need not sign any supplemental indenture that adversely affects
its rights.

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. The exchange of copies of this Indenture and of signature pages by facsimile or PDF

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. 

Section 10.15 Securities in a Foreign Currency. Unless otherwise specified in a Board Resolution, a supplemental indenture hereto

percentage in aggregate 

  
 -38- 

 
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 in a coin or currency other than Dollars, 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 that amount of Dollars
that could be obtained for such amount at the Market Exchange Rate at such time. For purposes of this Section 10.15, “Market Exchange Rate” shall mean the noon Dollar buying rate in New York City for cable transfers of that
currency as published by the Federal Reserve Bank of New York. If such Market Exchange Rate is not available for any reason with respect to such currency, the Company shall use, in its sole discretion and without liability on its part, such
quotation of the Federal Reserve Bank of New York as of the most recent available date, or quotations from one or more major banks in The City of New York or in the country of issue of the currency in question or such other quotations as the
Company, shall deem appropriate. 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 of the Company regarding the Market Exchange Rate or any alternative determination provided for in the preceding paragraph shall be in its sole
discretion and shall, in the absence of manifest error, to the extent permitted by law, be conclusive for all purposes and irrevocably binding upon the Company, the Trustee and all Holders. The Trustee shall have no duty to calculate or verify the
calculations made pursuant to this Section 10.15.

accordance with Section 326 of the U.S.A. Patriot Act, the Trustee, like all financial institutions, and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify, and record information that identifies
each person or legal entity that establishes a relationship or opens an account with the Trustee. The Company agrees that it will provide the Trustee with such information as it may reasonably request as required in order for the Trustee to satisfy
the requirements of the U.S.A. Patriot Act. 
 Section 10.17 Waiver of Jury Trial. EACH OF THE COMPANY AND THE TRUSTEE HEREBY
IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING AS BETWEEN THE COMPANY AND THE TRUSTEE ONLY ARISING OUT OF OR RELATING TO THIS INDENTURE OR THE SECURITIES. 

ARTICLE XI 
 SINKING
FUNDS 
 Section 11.01 Applicability of Article. The provisions of this Article shall be applicable to any sinking fund for
the retirement of the Securities of a Series, 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 

  
 -39- 

 
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 11.02. 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. 
 Section
11.02 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 Officers’ Certificate with 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 11.02, 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. 

Section 11.03 Redemption of Securities for Sinking Fund. Not less than 45 days (unless otherwise indicated in the Board
Resolution, supplemental indenture or Officers’ 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
Officers’ 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 11.02, 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, Officers’ 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 3.02 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 3.03. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 3.04, 3.05 and
3.06.

 ARTICLE II. 

GENERAL TERMS AND CONDITIONS OF THE NOTES 

Section 2.01 Designation and Principal Amount. 

The Notes are hereby authorized and are designated the “2.75% Convertible Senior Notes due 2034.” The Notes issued on the
Issue Date pursuant to the terms of this Indenture will be in an initial aggregate principal amount of $201,250,000, which amount shall be set forth in a written order of the Company for the authentication and delivery of the Notes pursuant to
Section 2.03 of the Base Indenture. In addition, the Company may from time to time, without the consent of the Holders, reopen the Indenture and issue additional Notes under the Indenture with the same terms (other than the date of issuance
and, in some cases, the date from which interest will initially accrue) as the Notes issued on the Issue Date in an unlimited aggregate principal amount; provided that if any such additional Notes are not fungible with the Notes issued on the
Issue Date for U.S. federal income tax purposes, such additional Notes will have a separate CUSIP number. The Notes issued on the Issue Date and any such additional Notes would be treated as a single class for all purposes under the Indenture and
would vote together as one class on all matters with respect to the Notes. 
 Section 2.02 Maturity. 

The principal amount of the Notes will be payable on the Maturity Date. 

Section 2.03 Form and Payment. 

The Notes will be issued as global notes, in fully registered book-entry form without coupons in minimum denominations of $1,000 and integral
multiples of $1,000. 
 Principal and/or interest, if any, on the global notes representing the Notes will be made to The Depository Trust
Company (the “Depositary”). 
 The global notes representing the Notes will be deposited with, or on behalf of, the
Depositary and will be registered in the name of the Depositary or a nominee of the Depositary. No global note may be transferred except as a whole by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the
Depositary or such nominee to a successor of the Depositary or a nominee of such successor. 
 So long as the Depositary or its nominee is
the registered owner of a global note, the Depositary or its nominee, as the case may be, will be the sole Holder of the Notes represented thereby for all purposes under the Indenture. Except as otherwise provided herein, each actual purchaser of
each Note represented by a global note (“Beneficial Owner”) will not be entitled to receive physical delivery of certificated Notes and will not be considered the Holders thereof for any purpose under the Indenture, and no global
note representing the Notes shall be exchangeable or transferable. Accordingly, each Beneficial Owner must rely on the procedures of the Depositary and, if such Beneficial Owner is not a participant, on the procedures of the participant through
which such Beneficial Owner owns its interest in order to exercise any rights of a Holder under such global note or the Indenture. 

  
 8 

 The global notes representing the Notes will be exchangeable for certificated Notes of like tenor
and terms and of differing authorized denominations aggregating a like principal amount, only if (i) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for the global debt securities and a successor to
the Depositary is not appointed within 90 days, (ii) the Depositary ceases to be a clearing agency registered under the Exchange Act and a successor to the Depositary is not appointed by the Company within 90 days, (iii) the Company in its
sole discretion determines that the global notes shall be exchangeable for certificated Notes and notifies the Trustee in writing of such determination or (iv) there shall have occurred and be continuing an Event of Default under the Indenture
with respect to the Notes and any Beneficial Owner requests that its Notes be issued in physical, certificated form. Upon any such exchange, the certificated Notes shall be registered in the names of the Beneficial Owners of the global notes
representing the Notes, which names shall be provided by the Depositary’s relevant participants (as identified by the Depositary) to the Trustee. In such event the Company will execute, and subject to Section 2.03 of the Base Indenture,
the Trustee, upon receipt of an Officers’ Certificate evidencing such determination by the Company, will authenticate and deliver the Notes in definitive registered form without coupons, in authorized denominations, and in an aggregate
principal amount equal to the principal amount of the global notes in exchange for such global notes. Upon the exchange of the global notes for such Notes in definitive registered form without coupons, in authorized denominations, the global notes
shall be cancelled by the Trustee. Such Notes in definitive registered form issued in exchange for the global notes shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or
indirect participants or otherwise, shall instruct the Trustee in writing. The Trustee shall deliver such Notes to the Depositary for delivery to the Persons in whose names such Notes are so registered. 

Section 2.04 Interest. 

The Notes shall bear interest at a rate equal to 2.75% per year. Interest on the Notes shall be computed on the basis of a 360-day year
comprised of twelve 30-day months, and shall accrue from February 4, 2014, or from the most recent Interest Payment Date to which interest has been paid or duly provided upon for the Notes, as the case may be. Interest on the Notes shall be
payable semi-annually in arrears on February 1 and August 1, commencing August 1, 2014 (each an “Interest Payment Date”), to the persons in whose names the Notes are registered at the Close of Business on
January 15 and July 15 (whether or not a Business Day), as the case may be, preceding such Interest Payment Date (a “Regular Record Date”). 

Payments of the Fundamental Change Repurchase Price, Repurchase Price, Redemption Price, principal and interest that are not made when due
will accrue interest per annum at the then-applicable interest rate plus one percent from the required payment date. 
 Section 2.05
Transfer, Exchange and Conversion. 
 In addition to its obligations under Section 2.04 of the Base Indenture, the Company shall
also cause to be kept at one of the offices or agencies maintained pursuant to Section 2.04 of the Base Indenture an office in the United States where Notes may be presented for conversion (the “Conversion Agent”), transfer or
exchange. 

  
 9 

 The Company initially appoints the Trustee as Paying Agent, Registrar and Conversion Agent for
the Notes. 
 The Company reserves the right to: 

(i) vary or terminate the appointment of the Registrar, Paying Agent or Conversion Agent; 

(ii) appoint additional Paying Agents or Conversion Agents; or 

(iii) approve any change in the office through which any Registrar or any Paying Agent or Conversion Agent acts. 

The Company shall not be required to transfer or exchange any Note surrendered for repurchase or conversion except for any portion of that
Note not being repurchased or converted, as the case may be. 
 Section 2.06 Repurchase and Cancellation. 

Each of the Registrar, Paying Agent and Conversion Agent (if other than the Trustee) will forward to the Trustee any Notes surrendered to it by
Holders for transfer, exchange, payment or conversion. All Notes delivered to the Trustee shall be cancelled promptly by the Trustee in the manner provided in the Base Indenture and may not be reissued or resold. No Notes shall be authenticated in
exchange for any Notes cancelled, except as provided in the Base Indenture. 
 The Company may, to the extent permitted by law, and directly
or indirectly (regardless of whether such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, whether by the Company or its subsidiaries or through private or public tender or exchange offer or through
counterparties to private agreements, including cash-settled swaps or other derivatives. The Company shall cause any Notes so repurchased (other than Notes repurchased pursuant to cash-settled swaps or other derivatives) to be surrendered to the
Trustee for cancellation, and such Notes will no longer be considered “outstanding” under the Indenture upon their repurchase. 

ARTICLE III. 

REDEMPTION AND REPURCHASE 

Section 3.01 Redemption. 

(a) Prior to February 6, 2018, the Company may not redeem the Notes. On or after February 6, 2018 and prior to February 6, 2021,
the Company may redeem any or all of the Notes (other than Notes for which the Company repurchase right provided under Section 3.02 have been exercised on or before the Close of Business on the Business Day immediately prior to the applicable
Redemption Date) (such redemption, a “Provisional Redemption”) on any Business Day (a “Provisional Redemption Date”) in cash at the Redemption Price; provided that the Closing Sale Price of the Common Stock

 10 

 (b) On or after February 6, 2021, the Company may redeem any or all of the Notes (other than

Date”) in cash at the Redemption Price.

(ii) the Redemption Date; 

(iii) the Redemption Price;

accordance with Section 3.01, the number of additional shares of Common Stock specified in Section 5.07 to be issuable upon such conversion of the Note; 

(vi) the names and addresses of the Paying Agent and the Conversion Agent; 

(vii) the procedures a Holder must follow to convert its Notes; 

(viii) that Notes called for redemption must be surrendered to the Paying Agent to collect the Redemption Price therefor; 

  
 11 

 (ix) the CUSIP number or numbers, as the case may be, of the Notes to be
redeemed; and 
 (x) in case any Note is to be redeemed in part only, the portion of the principal amount thereof to be
redeemed and that on and after the Redemption Date, upon surrender of such Note, a new Note in principal amount equal to the unredeemed portion thereof shall be issued. 

(d) Section 3.02 of the Base Indenture shall not apply to, and have no force and effect with respect to, the Notes and any reference to
Section 3.02 of the Base Indenture with respect to the Notes shall be superseded by and references thereto shall be deemed to refer to this Section 3.01(d). If the Company does not redeem all of the Notes, the Trustee shall select the
Notes to be redeemed in principal amounts of $1,000 or integral multiples of $1,000, from Notes then outstanding and not already redeemed as a result of having previously been called for redemption, in accordance with the procedures of the
Depositary. If the Trustee selects a portion of a Holder’s Notes for partial redemption and such Holder converts a portion of such Holder’s Note, the converted portion shall be deemed to be from the portion selected for redemption to the
extent that the converted portion does not exceed the portion selected for redemption. The Trustee shall promptly notify the Company in writing of the Notes selected for redemption and the principal amount thereof to be redeemed. If any Notes are to
be redeemed in part only, the Company shall issue new Notes in principal amount equal to the unredeemed principal portion thereof; provided, that the Company shall not be required to (i) issue, register the transfer of or exchange any
Notes during a period beginning at the open of business 15 days before the mailing of a Redemption Notice and ending at the close of business on the earliest date on which the relevant Redemption Notice is deemed to have been given to all Holders of
Notes to be redeemed or (ii) register the transfer of or exchange any Notes so selected for redemption, in whole or in part, except the unredeemed portion of any Notes being redeemed in part. 

(e) With respect to any Notes that are converted in connection with a Provisional Redemption in accordance with Section 5.07, the Company
shall, if applicable, increase the Conversion Rate for the Notes so surrendered for conversion by a number of Additional Shares in accordance with Section 5.07. 

(f) No Notes may be redeemed if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or
prior to the Redemption Date. 
 (g) If, by 11:00 a.m., New York City time on the applicable Redemption Date, the Paying Agent holds money
sufficient to make payment of the Redemption Price on all the Notes or portions thereof that are to be redeemed on such Redemption Date, then (i) such Notes will cease to be outstanding, (ii) interest will cease to accrue on such Notes
(whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to the Trustee or Paying Agent) and (iii) all other rights of the Holders of such Notes will terminate (other than the right to receive the
Redemption Price and previously accrued but unpaid interest); provided, that, if the Redemption Date is after a Regular Record Date and on or prior to the immediately following Interest Payment Date, then accrued and unpaid interest on such Notes
to, but excluding, such Interest Payment Date shall be paid, on such Interest Payment Date, to the Holder of record of such Notes at the close of business on such Regular Record Date without any requirement to surrender such Notes to the Paying
Agent. The Paying Agent shall return to the Company, as soon as practicable and upon receipt of written instructions, any money not required for that purpose. 

  
 12 

 (h) If the Redemption Price of any Note shall not be fully and duly paid in accordance with this
Section 3.01, the portion of the Redemption Price that is not so paid shall bear interest pursuant to Section 2.04, and such Note shall continue to be convertible pursuant to Article V of this First Supplemental Indenture, until such
Redemption Price and accrued interest have been paid. 
 Section 3.02 Repurchase at Option of Holders Upon a Fundamental Change.

 (a) Upon the occurrence of a Fundamental Change prior to the Maturity Date, each Holder will have the option to require the Company to
repurchase for cash (a “Fundamental Change Repurchase Right”) all or any portion of such Holder’s Notes that is equal to $1,000, or an integral multiple of $1,000, on the day of the Company’s choosing that is not less than
20 or more than 35 Business Days after the later of the occurrence of such Fundamental Change and the date the Company gives notice of the Fundamental Change (such day, the “Fundamental Change Repurchase Date”) at the Fundamental
Change Repurchase Price. 
 (b) A Holder must deliver written notice (a “Fundamental Change Repurchase Notice”) of its
exercise of this Fundamental Change Repurchase Right to the Paying Agent during the period between the delivery of the Fundamental Change Notice and the Close of Business on the Business Day immediately preceding the Fundamental Change Repurchase
Date in the form set forth in the global note attached as Exhibit A to this Indenture, in each case duly completed and signed, with appropriate signature guarantee, specifying the Notes for which the Fundamental Change Repurchase Right is
being exercised. If a Holder wishes to withdraw this election, it must provide a written notice of withdrawal to the Paying Agent at any time until the Close of Business on the Business Day immediately preceding the Fundamental Change Repurchase
Date. If the Notes are not in certificated form, the notice given by each Holder (and any withdrawal notice) must comply with applicable Depositary procedures. 

(c) The Company shall mail to the Trustee and to each Holder a written notice of a Fundamental Change (the “Fundamental Change
Notice”) within ten Business Days after the occurrence of such Fundamental Change. This Fundamental Change Notice shall state: 

(i) the events causing the Fundamental Change; 

(ii) the effective date of the Fundamental Change, and whether the Fundamental Change is a Make-Whole Fundamental Change; 

(iii) the last date on which a Holder may exercise the Fundamental Change Repurchase Right; 

(iv) the Fundamental Change Repurchase Price; 

(v) the Fundamental Change Repurchase Date; 

  
 13 

 (vi) the Conversion Rate and, in the case of any conversion of the Note in
connection with a Make-Whole Fundamental Change, the number of additional shares of Common Stock specified in Section 5.07 to be issuable upon such conversion of the Note, and the procedures required for exercise of a Holder’s right to
convert its Notes, including in the event of a Make-Whole Fundamental Change; 
 (vii) the procedures required for exercise
of the Fundamental Change Repurchase Right, and the procedures required for withdrawal of any such exercise; and 
 (viii)
the name and address of the Paying Agent and Conversion Agent. 
 No failure of the Company to give a Fundamental Change Notice shall limit any
Holder’s right pursuant hereto to exercise their Fundamental Change Repurchase Right. 
 (d) The Company shall be required to repurchase
Notes that have been validly surrendered for repurchase and not validly withdrawn on the Fundamental Change Repurchase Date. The Holder will receive payment of the Fundamental Change Repurchase Price on the later of the Fundamental Change Repurchase
Date and the time of book-entry transfer or the delivery of such Holder’s Notes. If the Paying Agent as of 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date holds money sufficient to pay the Fundamental Change Repurchase
Price of the Notes for which a Fundamental Change Repurchase Notice has been submitted and not validly withdrawn, then: 

(i) such Notes shall cease to be outstanding and interest will cease to accrue (whether or not book-entry transfer of the Notes
is made or whether or not the Note is delivered to the Paying Agent); and 
 (ii) all other rights of the relevant Holders of
such Notes shall terminate (other than the right to receive the Fundamental Change Repurchase Price and, if the Fundamental Change Repurchase Date is after a Regular Record Date and on or prior to the related Interest Payment Date, the right of the
Holder on such Regular Record Date to receive the related interest payment). 
 (e) No Notes may be repurchased by the Company at the option
of Holders upon a Fundamental Change if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to the Fundamental Change Repurchase Date (except in the case of an acceleration resulting from
a default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes). The Paying Agent shall promptly return to the respective Holders thereof any Notes held by it during the continuance of such an
acceleration. 
 (f) In connection with any Fundamental Change Repurchase Right, the Company shall, to the extent applicable: 

(i) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act, to the extent
such rules as applicable; 

  
 14 

 (ii) file a Schedule TO or any successor or similar schedule, if required, under
the Exchange Act; and 
 (iii) otherwise comply with all applicable federal and state securities laws. 

Section 3.03 Repurchase at Option of Holders Upon Specified Dates. 

(a) Each Holder will have the option to require the Company to repurchase all or a portion of their Notes for cash (“Repurchase
Right”) on February 6, 2021, February 6, 2024, and February 6, 2029 (each a “Repurchase Date” and together, the “Repurchase Dates”) at the Repurchase Price. The Repurchase Price will be
payable in cash and the Company will be required to repurchase any outstanding Notes for which a Holder delivers a written Repurchase Notice to the Paying Agent. 

(b) A Holder must deliver a written Repurchase Notice of its exercise of this Repurchase Right to the Paying Agent during the period beginning
at the Open of Business on the date that is 20 Business Days prior to the Repurchase Date until the Close of Business on the Business Day immediately preceding the Repurchase Date. If a Holder wishes to withdraw this election, it must provide a
written notice of withdrawal to the Paying Agent at any time until the Close of Business on the Business Day immediately preceding the Repurchase Date. If the Notes are not in certificated form, the notice given by each Holder (and any withdrawal
notice) must comply with applicable Depositary procedures. 
 (c) The Company shall mail to the Trustee and to each Holder a written notice
(the “Holder Option to Repurchase Notice”) on a date not less than 20 Business Days prior to each Repurchase Date. This Holder Option to Repurchase Notice shall state certain specified information, including: 

(i) that Holders have a right to require the Company to repurchase the Notes upon satisfaction of the requirements set forth in
this Section 3.03; 
 (ii) the Repurchase Date; 

(iii) the Repurchase Price; 

(iv) that Notes with respect to which a Repurchase Notice is given by a Holder may be converted pursuant to Article V of this
First Supplemental Indenture only if such Repurchase Notice has been withdrawn in accordance with this Section 3.03 or if there shall be a default in the payment of such Repurchase Price payable as herein provided; 

(v) the Conversion Rate; 

(vi) the names and addresses of the Paying Agent and the Conversion Agent; 

  
 15 

 (vii) the procedures a Holder must follow for exercise of the Repurchase Right
and the procedures required for withdrawal of any such exercise; 
 (viii) that Notes called for redemption must be
surrendered to the Paying Agent to collect the Repurchase Price therefor; and 
 (ix) the CUSIP number or numbers, as the
case may be, of the Notes to be redeemed. 
 No failure of the Company to give a Holder Option to Repurchase Notice shall limit any Holder’s right
pursuant hereto to exercise their Repurchase Right. 
 (d) The Company shall be required to repurchase Notes that have been validly
surrendered for repurchase and not validly withdrawn on the Repurchase Date. The Holder will receive payment of the Repurchase Price on the later of the Repurchase Date and the time of book-entry transfer or the delivery of such Holder’s Notes.
If the Paying Agent as of 11:00 a.m., New York City time, on the Repurchase Date holds money sufficient to pay the Repurchase Price of the Notes for which a Repurchase Notice pursuant to this Section 3.03 has been submitted and not validly
withdrawn, then: 
 (i) such Notes shall cease to be outstanding and interest will cease to accrue (whether or not book-entry
transfer of the Notes is made or whether or not the Note is delivered to the Paying Agent); and 
 (ii) all other rights of
the relevant Holders of such Notes shall terminate (other than the right to receive the Repurchase Price and, if the Repurchase Date is after a Regular Record Date and on or prior to the related Interest Payment Date, the right of the Holder on such
Regular Record Date to receive the related interest payment). 
 (e) No Notes may be repurchased by the Company at the option of Holders upon
their exercise of a Repurchase Right if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to the Repurchase Date (except in the case of an acceleration resulting from a default by the
Company in the payment of the Repurchase Price with respect to such Notes). The Paying Agent shall promptly return to the respective Holders thereof any Notes held by it during the continuance of such an acceleration. 

(f) In connection with any repurchase by the Company upon a Holder’s exercise of its Repurchase Right, the Company shall, to the extent
applicable: 
 (i) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange
Act, to the extent such rules as applicable; 
 (ii) file a Schedule TO or any successor or similar schedule, if required,
under the Exchange Act; and 
 (iii) otherwise comply with all applicable federal and state securities laws.

 Section 3.04 No Sinking Fund. 

No sinking fund is provided for the Notes, and Article XI of the Base Indenture is inapplicable with respect to the Notes. 

ARTICLE IV. 

CONSOLIDATION, MERGER AND SALE OF ASSETS 

Article V of the Base Indenture shall not apply to, and have no force and effect with respect to, the Notes and any reference to Article VIII
of the Base Indenture with respect to the Notes shall be superseded by and references thereto shall be deemed to refer to this Article IV. 

The Company shall not consolidate with, or merge with or into, enter into any combination or binding share exchange with, another Person or
sell, assign, convey, transfer, lease or otherwise dispose in one transaction or a series of transactions of all or substantially all of the consolidated assets of the Company and its Subsidiaries, taken as a whole, to any successor Person unless:

 (i) the successor Person, if any, is a corporation organized and existing under the laws of the United States of America
or any state thereof or the District of Columbia and expressly assumes by supplemental indenture all the obligations of the Company under the Notes and the Indenture; 

(ii) immediately after giving effect to the transaction, no default or Event of Default with respect to the Notes shall have
occurred and be continuing; and 
 (iii) the Company shall deliver to the Trustee prior to the consummation of the proposed
transaction an Officers’ Certificate to the foregoing effect and an Opinion of Counsel (which may rely upon such Officers’ Certificate as to the absence of defaults and Events of Default) stating that the proposed transaction and such
supplemental indenture will, upon consummation of the proposed transaction, comply with this Indenture. 
 Upon any such consolidation,
merger, combination, binding share exchange, or sale, assignment, conveyance, transfer, lease or other disposition, the resulting, surviving or transferee corporation (if not the Company) shall succeed to the Company, and may exercise every right
and power of the Company, under this Indenture, and the Company shall be discharged from its obligations under the Notes and this Indenture except in the case of any such lease. For purposes of the foregoing, any sale, assignment, conveyance,
transfer, lease or other disposition of the assets of one or more of the Company’s Subsidiaries that would, if the Company had held such assets directly, have constituted the sale, assignment, conveyance, transfer, lease or other disposition of
all or substantially all of the consolidated assets of the Company and its Subsidiaries, taken as a whole, will be treated as such under this Indenture.

 ARTICLE V. 

CONVERSION OF NOTES 

Section 5.01 Right to Convert. 

(a) At any time prior to the Close of Business on the Business Day immediately preceding the Maturity Date, a Holder may convert all or any
portion of its Notes at the Conversion Rate in effect on the Conversion Date. A Holder may convert fewer than all of such Holder’s Notes so long as the Notes converted are in an integral multiple of $1,000 principal amount. 

(b) Upon conversion of a Note, a Holder will not receive any additional cash payment for accrued and unpaid interest, if any, unless such
Holder is the Holder on a Regular Record Date and such conversion occurs between such Regular Record Date and the Interest Payment Date to which it relates as described in Section 5.01(c), and the Company will not adjust the Conversion Rate to
account for accrued and unpaid interest. Except as described in Section 5.01(c), the Company’s settlement of conversions pursuant to Section 5.03 shall be deemed to satisfy the Company’s obligation to pay the principal amount of
the Note and accrued and unpaid interest, if any, to, but not including, the Conversion Date. 
 (c) Holders at the Close of Business on a
Regular Record Date will receive payment of interest payable on the corresponding Interest Payment Date notwithstanding the conversion of such Notes at any time after the Close of Business on the applicable Regular Record Date. Notes surrendered for
conversion by a Holder after the Close of Business on any Regular Record Date but prior to the next Interest Payment Date must be accompanied by payment of an amount equal to the interest that will be payable on the Notes; provided,
however, that no such payment shall be required (1) if the Company has specified a Fundamental Change Repurchase Date following a Fundamental Change that is after a Regular Record Date and on or prior to the corresponding Interest
Payment Date, (2) if the Company has specified a Redemption Date in accordance with Section 3.01 that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date, (3) with respect to any Notes surrendered
for conversion following the Regular Record Date immediately preceding the Maturity Date or (4) only to the extent of overdue interest, if any overdue interest exists at the time of conversion with respect to such Notes. For the avoidance of
doubt, all Holders on the Regular Record Date immediately preceding the Maturity Date will receive and retain the full interest payment due on the Maturity Date regardless of whether their Notes are converted following such Regular Record Date. 

(d) If the Company calls any or all of the Notes for redemption under Section 3.01, Holders shall have the right to convert all or a
portion of their Notes called for redemption at any time prior to the Close of Business on the Business Day immediately preceding the Redemption Date, after which time Holders shall no longer have the right to convert their Notes on account of the
Company’s delivery of such Redemption Notice, unless the Company defaults in the payment of the Redemption Price. If a Holder elects to convert its Notes in connection with a Provisional Redemption, the Company shall, if applicable, increase
the Conversion Rate for the Notes so surrendered for conversion by a number of Additional Shares in accordance with Section 5.07. 

  
 18 

 (e) The Company shall pay any documentary, stamp or similar issue or transfer tax due on the
issuance of the shares of the Common Stock upon conversion of the Notes, unless the tax is due because the Holder requests such shares of Common Stock to be issued in a name other than the Holder’s name, in which case the Holder shall pay the
tax. 
 Section 5.02 Exchange in Lieu of Conversion. 

(a) If at any time when a Holder surrenders Notes for conversion prior to the Maturity Date of the Notes, the Company: 

(i) has designated a financial institution, which shall be a direct or indirect Depositary participant (a “Designated
Institution”), to accept such Notes in exchange for shares of Common Stock (including cash for any fractional shares) due upon conversion as provided in Section 5.03; and 

(ii) notifies the Holder surrendering such Notes for conversion by the second Trading Day after the applicable Conversion Date,
that it has directed the Designated Institution to make an exchange in lieu of conversion, then, notwithstanding anything in this Indenture to the contrary, the Company may direct the Conversion Agent to surrender such Notes to the Designated
Institution for exchange in lieu of conversion. 
 (b) If the Designated Institution accepts Notes surrendered for exchange, it shall deliver
shares of Common Stock (including cash for any fractional shares) to the Conversion Agent and the Conversion Agent will deliver shares of Common Stock (including cash for any fractional shares) to such Holder on the third Business Day immediately
following the Conversion Date. Any Notes so exchanged by such Designated Institution shall remain outstanding for all purposes under this Indenture. 

(c) If the Designated Institution agrees to accept any Notes for exchange but does not timely deliver the related consideration to the
Conversion Agent, or if the Designated Institution does not accept such Notes for exchange, the Company shall, within the time period specified in Section 5.03(c), convert such Notes into shares of Common Stock (including cash for any
fractional shares) in accordance with the provisions of Section 5.03. 
 For the avoidance of doubt, in no event will the Company’s designation of
a financial institution pursuant to this Section 5.02 require such financial institution to accept any Notes for exchange. 

Section 5.03 Settlement upon Conversion. 

(a) Upon conversion, the Company shall deliver to Holders in respect of each $1,000 principal amount of Notes being converted a number of
shares of Common Stock equal to the Conversion Rate in effect immediately prior to the Close of Business on the relevant Conversion Date. No fractional shares will be issued upon conversion. Instead, the Company will pay cash in lieu of any
fractional share based on the Closing Sale Price of the Common Stock on the relevant Conversion Date. 
 (b) Each conversion will be deemed
to have been effected as to any Notes surrendered for conversion on the Conversion Date, and with respect to the shares of Common Stock that are issuable upon such conversion, the Person in whose name the certificate or certificates for such shares
will be registered shall be treated as the holder of record of such shares as of the Close of Business on the Conversion Date. 

  
 19 

 (c) The Company shall deliver the consideration due in respect of any conversion on the third
Business Day immediately following the relevant Conversion Date. 
 Section 5.04 Conversion Procedures. 

(a) (1) If a Note is represented by a certificated security, to exercise its right of conversion, a Holder must: 

(i) complete and manually sign the Conversion Notice, with the appropriate signature guarantee, or facsimile of the Conversion
Notice and deliver the completed Conversion Notice (which shall be irrevocable) to the Conversion Agent; 
 (ii) surrender
the certificated Note to the Conversion Agent; 
 (iii) furnish appropriate endorsements and transfer documents if required
by the Registrar or Conversion Agent; 
 (iv) pay all transfer or similar taxes if required pursuant to Section 5.01(e);
and 
 (v) pay funds equal to interest payable on the next Interest Payment Date required by Section 5.01(c), if any, or

 (2) If a Note is represented by a global security, to exercise its right of conversion, a Holder must comply with
Section 5.04(a)(1)(iv) and Section 5.04(a)(1)(v) above and the Depositary’s procedures for converting a beneficial interest in a global security. 

(b) If a Holder has submitted its Notes for repurchase upon a Fundamental Change or on a Repurchase Date, such Holder may only convert its
Notes if it withdraws its Fundamental Change Repurchase Notice or Repurchase Notice, as the case may be, prior to the Fundamental Change Repurchase Date or the applicable Repurchase Date, pursuant to Section 3.02(b) or 3.03(b), as the case may
be. If such Holder’s Notes are submitted for repurchase upon a Fundamental Change or on a Repurchase Date, such Holder’s right to withdraw its Fundamental Change Repurchase Notice or Repurchase Notice, as the case may be, and convert its
Notes that are subject to repurchase will terminate at the Close of Business on the Business Day immediately preceding the Fundamental Change Repurchase Date or applicable Repurchase Date, as the case may be. 

Section 5.05 Conversion Rate Adjustments. 

The Conversion Rate shall be subject to adjustment from time to time, without duplication, upon the occurrence of any of the following events,
provided, that the Company will not make any adjustments to the Conversion Rate if Holders of the Notes participate (other than 

  
 20 

 
in the case of (x) a share split or share combination or (y) a tender or exchange offer), at the same time and upon the same terms as Holders of our Common Stock and solely as a result
of holding the Notes, in any of the transactions described below without having to convert their Notes as if they held a number of shares of Common Stock equal to the Conversion Rate, multiplied by the principal amount of Notes held by such
Holder, divided by $1,000: 
 (a) If the Company issues solely shares of Common Stock as a dividend or distribution on all or
substantially all of its shares of Common Stock, or if the Company subdivides or combines Common Stock, the Conversion Rate shall be adjusted based on the following formula: 
  

													
		 		 	CR1 = CR0 x	 	 OS1
	  		  		  	
		 		 	 	OS0	  		  		  	

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such dividend or distribution, or immediately prior to the Open of Business on the effective date of such subdivision or combination
of Common Stock, as the case may be;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution, or effective date of such subdivision or combination of Common Stock, as the case may be;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the Open of Business on the Ex-Dividend Date for such dividend or distribution or the effective date of such subdivision or combination of Common Stock, as the
case may be; and
			
	OS1	  	=	  	the number of shares of Common Stock that would be outstanding immediately after giving effect to such dividend or distribution, or immediately after the effective date of such subdivision or combination of Common Stock, as the case
may be.

 Any adjustment made under this Section 5.05(a) shall become effective immediately after the Open of Business on the
Ex-Dividend Date for such dividend or distribution or effective date of such subdivision or combination of Common Stock, as the case may be. If such dividend, distribution, subdivision or combination described in this Section 5.05(a) is
declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution or to effect such subdivision or combination, to the
Conversion Rate that would then be in effect if such dividend or distribution had not been declared or subdivision or combination had not been announced. 

  
 21 

 (b) If an Ex-Dividend Date occurs for a distribution to all or substantially all holders of
Common Stock of any rights, options or warrants entitling such holders for a period of not more than 60 calendar days from the announcement date for such distribution to subscribe for or purchase shares of Common Stock, at a price per share less
than the average of the Closing Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the announcement date for such distribution, the Conversion Rate shall be
increased based on the following formula: 
  

													
		 		 	CR1 = CR0 x	 	 (OS0 + X)
	  		  		  	
		 		 	 	(OS0 + Y)	  		  		  	

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to 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 the Ex-Dividend Date for such distribution;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the Open of Business on the Ex-Dividend Date for such distribution;
			
	X	  	=	  	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
			
	Y	  	=	  	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants divided by the average of the Closing Sale Prices of Common Stock over the 10 consecutive Trading Day
period ending on, and including, the Trading Day immediately preceding the announcement date for such distribution.

 Any adjustment made under this Section 5.05(b) will become effective immediately after the Open of Business on the
Ex-Dividend Date for such distribution. Any increase made under this Section 5.05(b) shall be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the Open of Business on the
Ex-Dividend Date for such distribution. To the extent that shares of Common Stock are not delivered after the exercise of such rights, options or warrants, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect
had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so distributed, the
Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect if the Record Date for such distribution had not occurred. 

For purposes of this Section 5.05(b), in determining whether any rights, options or warrants entitle the Holders to subscribe for or
purchase shares of Common Stock at a price that is less than the average of the Closing Sale Prices of the Common Stock over the applicable 10 consecutive Trading Day period and in determining the aggregate price payable for such shares of the
Common Stock, there shall be taken into account any consideration the Company receives for such rights, options or warrants and any amount payable on exercise or conversion thereof, with the value of such consideration if other than cash to be
determined in good faith by the Board of Directors. 

  
 22 

 (c) (A) If an Ex-Dividend Date occurs for a distribution (a “Relevant
Distribution”) of shares of the Company’s capital stock, evidences of the Company’s indebtedness or other assets or property of the Company or rights, options or warrants to acquire the Company’s capital stock or other
securities, to all or substantially all holders of the Common Stock (excluding (i) dividends or distributions and rights, options or warrants as to which an adjustment was effected under Section 5.05(a) or Section 5.05(b) above;
(ii) dividends or distributions paid exclusively in cash covered under Section 5.05(d); and (iii) Spin-Offs), then the Conversion Rate shall be increased based on the following formula: 

 

													
		 		 	CR1 = CR0 x	 	 SP0
	  		  		  	
		 		 	 	(SP0 – FMV)	  		  		  	

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to 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 the Ex-Dividend Date for such distribution;
			
	SP0	  	=	  	the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and
			
	FMV	  	=	  	the fair market value (as determined in good faith by the Board of Directors) of the shares of capital stock, evidences of indebtedness, assets or property or rights, options or warrants distributed with respect to each outstanding
share of Common Stock as of the Open of Business on the Ex-Dividend Date for such distribution.

 Any increase made under the above portion of this Section 5.05(c) shall become effective immediately after the Open
of Business on the Ex-Dividend Date for such distribution. No adjustment pursuant to the above formula will result in a decrease of the Conversion Rate. However, if such distribution is not so paid or made, the Conversion Rate shall be readjusted to
be the Conversion Rate that would then be in effect if such distribution had not been declared. 
 Notwithstanding the foregoing, if
“FMV” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive (without having to
convert its notes), in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock, the amount and type of the Relevant Distribution that such Holder would have received if such Holder
owned a number of shares of Common Stock equal to the Conversion Rate on the Record Date for the distribution. 

  
 23 

 (B) With respect to an adjustment pursuant to this Section 5.05(c) where there has been an
Ex-Dividend Date for a dividend or other distribution on the Common Stock of shares of capital stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit, that are, or, when issued, will be,
listed or admitted for trading on a U.S. national securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula: 
  

													
		 		 	CR1 = CR0 x	 	 FMV + MP0
	  		  		  	
		 		 	 	MP0	  		  		  	

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for the Spin-Off;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date for the Spin-Off;
			
	FMV	  	=	  	the average of the Closing Sale Prices of the capital stock or similar equity interest distributed to holders of Common Stock applicable to one share of Common Stock (determined by reference to the definition of “Closing Sale
Price” as if references therein to Common Stock were to such capital stock or similar equity interest) over the first 10 consecutive Trading Day period commencing on, and including, the effective date for the Spin-Off (such period, the
“Valuation Period”); and
			
	MP0	  	=	  	the average of the Closing Sale Prices of the Common Stock over the Valuation Period.

 The adjustment to the Conversion Rate under the preceding paragraph of this Section 5.05(c) shall
be determined on the last day of the Valuation Period but will be given effect immediately after the Open of Business on the Ex-Dividend Date for the Spin-Off. In respect of any conversion during the Valuation Period for any Spin-Off, references
within this Section 5.05(c)(B) related to 10 Trading Days shall be deemed to be replaced with such lesser number of Trading Days as have elapsed from, and including, the effective date for such Spin-Off to, but excluding, the relevant
Conversion Date. 
 (d) If an Ex-Dividend Date occurs for a cash dividend or distribution to all or substantially all holders of the
outstanding Common Stock (other than any dividend or distribution in connection with the Company’s liquidation, dissolution or winding up), the Conversion Rate shall be increased based on the following formula: 

 

													
		 		 	CR1 = CR0 x	 	 SP0
	  		  		  	
		 		 	 	(SP0 – C)	  		  		  	

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to 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 the Ex-Dividend Date for such distribution;

  
 24 

 
					
	SP0	  	=	  	the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and
			
	C	  	=	  	the amount in cash per share of Common Stock the Company pays, or distributes, to all or substantially all holders of the Common Stock.

 Any increase made under this Section 5.05(d) shall become effective immediately after the Open of Business on the
Ex-Dividend Date for such dividend or distribution. No adjustment pursuant to the above formula will result in a decrease of the Conversion Rate. However, if any dividend or distribution described in this Section 5.05(d) is declared but not so
paid or made, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 

Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive (without having to convert its Notes) for each $1,000 principal amount of Notes, at the same time
and upon the same terms as holders of shares of Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate on the Record Date for such cash dividend or
distribution. 
 (e) If the Company or any of its Subsidiaries makes a payment in respect of a tender or exchange offer for the Common Stock
and, if the cash and value of any other consideration included in the payment per share of Common Stock exceeds the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the
Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer (the “Expiration Date”), the Conversion Rate shall be increased based on the following formula: 

 

													
		 		 	CR1 = CR0 x	 	 AC + (SP1 x OS1)
	  		  		  	
		 		 	 	(OS0 x SP1)	  		  		  	

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the Open of Business on the Trading Day next succeeding the Expiration Date;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the Open of Business on the Trading Day next succeeding the Expiration Date;
			
	AC	  	=	  	the aggregate value of all cash and any other consideration (as determined in good faith by the Board of Directors) paid or payable for shares of Common Stock purchased in such tender or exchange offer;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the time (the “Expiration Time”) such tender or exchange offer expires (prior to giving effect to the purchase of all shares accepted for
purchase or exchange in such tender or exchange offer);

  
 25 

 
					
	OS1	  	=	  	the number of shares of Common Stock outstanding immediately after the Expiration Time (after giving effect to the purchase of all shares accepted for purchase or exchange in such tender or exchange offer); and
			
	SP1	  	=	  	the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the Expiration Date.

 The adjustment to the Conversion Rate under this Section 5.05(e) shall be determined at the Close of Business on
the tenth Trading Day immediately following, but excluding, the Expiration Date but shall be given effect at the Open of Business on the Trading Day next succeeding the Expiration Date. In respect of any conversion during the 10 Trading Days
commencing on the Trading Day next succeeding the Expiration Date, references within this Section 5.05(e) to 10 Trading Days shall be deemed to be replaced with such lesser number of Trading Days as have elapsed from, and including, the Trading
Day next succeeding the Expiration Date to, but excluding, the relevant Conversion Date. No adjustment pursuant to the above formula will result in a decrease of the Conversion Rate. 

(f) To the extent that the Company has a rights plan in effect upon conversion of the Notes, the Holders shall receive, in addition to the
Common Stock received in connection with such conversion, the rights under the rights plan, unless prior to any conversion, the rights have separated from the Common Stock, in which case the Conversion Rate will be adjusted at the time of separation
as if the Company distributed to all holders of Common Stock, shares of the Company’s capital stock, evidences of indebtedness or other assets or property as described in Section 5.05(c), subject to readjustment in the event of the
expiration, termination or redemption of such rights. 
 (g) To the extent permitted by applicable law and applicable listing rules of the
Nasdaq Global Select Market and any other securities exchange on which the Company’s securities are then listed, (i) the Company is permitted to increase the Conversion Rate of the Notes by any amount for a period of at least 20 Business
Days so long as the increase is irrevocable during the period and the Board of Directors determines that such increase would be in the Company’s best interest and (ii) the Company may (but is not required to) increase the Conversion Rate
to avoid or diminish income tax to holders of the Common Stock or rights to purchase shares of the Common Stock in connection with a dividend or distribution of shares (or rights to acquire shares) or similar events. The Company must give at least
15 days’ prior notice of any such increase in the Conversion Rate. 
 (h) Adjustments to the Conversion Rate will be calculated to the
nearest 1/10,000th of a share of Common Stock. Notwithstanding anything in this Section 5.05 to the contrary, the Company shall not be required to adjust the Conversion Rate unless the adjustment would result in a change of at least 1% of the
Conversion Rate. However, the Company shall carry forward any adjustments that are less than 1% of the Conversion Rate and make such carried forward adjustments (1) when the cumulative net effect of all adjustments not yet made will result in a
change of at least 1% of the Conversion Rate or (2) regardless of whether the aggregate adjustment is less than 1%, (i) upon any required repurchases of the Notes in connection with a Fundamental Change and (ii) upon any conversion of
Notes. 

  
 26 

 (i) Whenever any provision of this Indenture requires the Company to calculate the Closing Sale
Prices or the Stock Price over a span of multiple days, the Board of Directors shall make appropriate adjustments to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion
Rate where the Record Date, the Ex-Dividend Date, the Expiration Date or the Effective Date of the event occurs, at any time during the period from which such Closing Sale Prices or Stock Prices are to be calculated. 

(j) If the Company issues rights, options or warrants that are only exercisable upon the occurrence of certain triggering events, then
(i) the Company will not adjust the Conversion Rate pursuant to the above provisions until the earliest of these triggering events occurs; and (ii) the Company will readjust the Conversion Rate to the extent any of these rights, options or
warrants are not exercised before they expire. 
 (k) If the Company adjusts the Conversion Rate pursuant to the above provisions, the
Company shall deliver to the Conversion Agent a certificate setting forth the Conversion Rate, detailing the calculation of the Conversion Rate and describing the facts upon which the adjustment is based. 

Section 5.06 Recapitalizations, Reclassifications and Changes to the Common Stock. 

In the event of: 
 (a) any
recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or combination or changes in par value); 

(b) a consolidation, merger, combination or binding share exchange involving the Company; or 

(c) a sale, assignment, conveyance, transfer, lease or other disposition, in one transaction or a series of transactions, of all or
substantially all of the consolidated assets of the Company and its Subsidiaries, taken as a whole, to any Person (provided that, for the avoidance of doubt, a pledge of the Company’s assets pursuant to any agreement governing secured
indebtedness shall not be deemed to be a sale, lease, transfer, conveyance or other disposition hereunder); 
 in each case, in which holders of outstanding
Common Stock are entitled to receive cash, securities or other property for their shares of Common Stock, the Company or the successor or purchasing company, as the case may be, shall execute with the Trustee a supplemental indenture, providing
that, at and after the effective time of such transaction, Holders of each $1,000 principal amount of Notes will be entitled to convert their Notes into the type and amount of shares of stock, other securities or other property or assets (including
cash or any combination thereof) that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such transaction would have owned or been entitled to receive upon such transaction (“Reference
Property”). The supplemental indenture shall also provide for anti-dilution and other adjustments that are as nearly equivalent as possible to the adjustments described under Section 5.05. If the Reference Property in respect of any
such transaction includes shares of stock, securities or other property or assets of a company other than the 

  
 27 

 
successor or purchasing corporation, as the case may be, in such transaction, such other company shall also execute such supplemental indenture, and such supplemental indenture shall contain such
additional provisions to protect the interests of the Holders, including the right of Holders to require the Company to repurchase their Notes upon a Fundamental Change as described in Section 3.02, as the Board of Directors reasonably
considers necessary by reason of the foregoing. If the Notes become convertible into Reference Property, the Company shall notify the Trustee. 

For purposes of the foregoing, the type and amount of consideration that holders of the Common Stock are entitled to in the case of
recapitalizations, reclassifications, changes of the Common Stock, consolidations, mergers, combinations, binding share exchanges, sales, assignments, conveyances, transfers, leases or other dispositions that cause the Common Stock to be converted
into or exchanged for the right to receive more than a single type of consideration because the holders of Common Stock have the right to elect the type of consideration they receive will be deemed to be the weighted average of the types and amounts
of consideration received by the holders of Common Stock that affirmatively make such an election. The Company shall notify Holders of the weighted average as soon as practicable after such determination is made. The Company shall not become a party
to any such transaction unless its terms are consistent with the foregoing. 
 Section 5.07 Adjustment to Conversion Rate upon
Conversion upon a Make-Whole Fundamental Change or a Provisional Redemption 
 (a) If a Holder elects to convert its Notes in connection
with (i) a Make-Whole Fundamental Change or (ii) a Provisional Redemption as provided in Section 3.01, then the Conversion Rate of such Notes shall be increased by an additional number of shares of Common Stock
(the “Additional Shares”) as described below. A conversion shall be deemed to be in connection with a Make-Whole Fundamental Change if the Conversion Notice is received by the Conversion Agent during the period
that begins on (and includes) the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”) and ends at the Close of Business on the Business Day immediately preceding the related Fundamental
Change Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the exception provided in clause (2) of the definition thereof, the 35th Trading Day immediately following the
Effective Date). A conversion of Notes will be deemed for these purposes to be “in connection with” such Provisional Redemption if a Holder converts its Notes at any time following the date of the Notice of Provisional Redemption up to,
and including, the Business Day prior to the Redemption Date for the Provisional Redemption. 
 (b) The number of Additional Shares, if any,
by which the Conversion Rate will be increased for conversions in connection with a (i) Make-Whole Fundamental Change or (ii) Provisional Redemption, will be determined by reference to the table below, based on the Effective Date or the
date of the Redemption Notice and (1) the price paid per share of the Common Stock in the case of a Make-Whole Fundamental Change described in clause (2) of the definition of “Fundamental Change,” in the event that the Common
Stock is acquired for cash, or, (2) the average of the Closing Sale Prices of the Common Stock over the five Trading Day period ending on the Trading Day immediately preceding the Effective Date of such other Make-Whole Fundamental Change or
the date of the Redemption Notice in the case of a Provisional Redemption. The amount determined under the first or second clause of the preceding sentence, as applicable, is referred to as the “Stock Price.” 

  
 28 

 The Stock Prices set forth in the first row of the table below (i.e., column headers) and the
number of Additional Shares in the table below will be adjusted as of any date on which the Conversion Rate of the Notes is adjusted pursuant to Section 5.05. The adjusted Stock Prices will equal the Stock Prices immediately prior to such
adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of
Additional Shares will be adjusted in the same manner and at the same time as the Conversion Rate pursuant to Section 5.05. 
 The
following table sets forth the number of Additional Shares by which the Conversion Rate for each $1,000 principal amount of Notes shall be increased based on the Stock Price and the Effective Date: 

 

																																																	
	 	  	Stock Price	 
	 Effective Date
	  	$ 39.96	 	  	$ 45.00	 	  	$ 50.00	 	  	$ 60.00	 	  	$ 75.00	 	  	$ 90.00	 	  	$ 105.00	 	  	$ 120.00	 	  	$ 135.00	 	  	$ 150.00	 	  	$ 165.00	 	  	$ 180.00

 (c) The exact Stock Price and Effective Date may not be set forth in the table in Section 5.07(b), in
which case if the Stock Price is: 
 (i) between two Stock Prices in the table or the Effective Date is between two Effective
Dates in the table, the number of Additional Shares will be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices and the earlier and later Effective Dates based on a
365-day year, as applicable; 
 (ii) in excess of $180.00 per share (subject to adjustment in the same manner as the Stock
Prices set forth in the column headings of the table above), the Conversion Rate will not be increased; and 
 (iii) less
than $39.96 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above), the Conversion Rate will not be increased. 

(d) Notwithstanding anything herein to the contrary, the Company may not increase the Conversion Rate to more than 25.0250 shares per $1,000
principal amount of Notes, provided that the Company will adjust such number of shares for the same events for which the Company will adjust the Conversion Rate pursuant to Section 5.05. 

  
 29 

 Section 5.08 Reserved Shares. 

The Company shall at all times reserve out of its authorized but unissued Common Stock a sufficient number of shares of Common Stock to permit
the conversion, in accordance herewith, of all of the Notes (assuming, for such purposes, that at the time of computation of such number of shares, all such Notes would be converted by a single Holder). The shares of Common Stock due upon conversion
of a global note shall be delivered by the Company in accordance with the Depositary’s customary practices. 
 All shares of Common
Stock issued upon conversion of the Notes shall be validly issued, fully paid and non-assessable and shall be free of preemptive or similar rights and free of any lien or adverse claim that arises from the action or inaction of the Company. 

The Company shall comply with all securities laws regulating the offer and delivery of shares of Common Stock upon conversion of the Notes and
shall list such shares on each national securities exchange or automated quotation system on which the shares of Common Stock are listed on the applicable Conversion Date. 

Section 5.09 Trustee Adjustment Disclaimer. 

The Trustee has no duty to determine when an adjustment under this Article V should be made, how it should be made or what it should be. The
Trustee has no duty to determine whether a supplemental indenture need be entered into or whether any provisions of any supplemental indenture are correct. The Trustee shall not be accountable for and makes no representation as to the validity or
value of any securities or assets issued upon conversion of the Notes. The Trustee shall not be responsible for making any calculations hereunder nor the Company’s failure to comply with this Article V. Each Conversion Agent (other than the
Company or an Affiliate of the Company) shall have the same protection under this Section 5.09 as the Trustee. 
 ARTICLE VI.

Section 6.01 Events of Default. 

Section 6.01 of the Base Indenture shall not apply to, and have no force and effect with respect to, the Notes and any reference to

Indenture by the Trustee or Holders of not less than 25% in aggregate principal amount of the outstanding Notes; 

(viii) (A) the Company’s failure, or the failure of any of the Company’s Significant Subsidiaries to make any
payment at maturity (after giving effect to any applicable grace period) of Indebtedness, in a principal amount in excess of $15.0 million and continuance of such failure, or (B) the acceleration of Indebtedness of the Company or any of the
Company’s Significant Subsidiaries in an amount in excess of $15.0 million because of a default with respect to such Indebtedness, unless such Indebtedness is discharged or such acceleration has been cured, waived, rescinded or annulled, in
either case within a period of 30 days after written notice to us given in accordance with this Indenture by the Trustee or Holders of not less than 25% in aggregate principal amount of the outstanding Notes, provided, however, that if any
such failure or acceleration referred to in (A) or (B) above shall cease or be cured, waived, rescinded or annulled, then the Event of Default by reason thereof shall be deemed not to have occurred; 

(ix) the entry of a decree or order for relief in respect of the Company or any of its Significant Subsidiaries by a court
having jurisdiction in the premises in an involuntary case under Bankruptcy Law, as now or hereafter constituted, or a decree or order adjudging the Company or any of its Significant Subsidiaries a bankrupt or insolvent, or approving as properly
filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Company or any of its Significant Subsidiaries under any applicable Federal or State law, or appointing a receiver, liquidator, assignee,
custodian, trustee, sequestrator (or other similar official) of the Company or any of its Significant Subsidiaries or of any substantial part of their respective properties, or ordering the winding up or liquidation of its affairs, and the
continuance of any such decree or order unstayed and in effect for a period of 60 consecutive days; and 
 (x) the
commencement by the Company or any of its Significant Subsidiaries of a voluntary case under the Bankruptcy Law, as now or hereafter constituted, or the consent by it to the entry of an order for relief in an involuntary case under any such law or
to the appointment of a receiver, liquidator, assignee, custodian, 

  
 31 

 
trustee, sequestrator (or other similar official) of the Company or any of its Significant Subsidiaries or of any substantial part of their respective properties, or the making by it of an
assignment for the benefit of its creditors, or the admission by it in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by the Company or any of its Significant Subsidiaries in furtherance of
any such action. 
 Section 6.02 Acceleration of Maturity; Rescission and Annulment. 

Section 6.02 of the Base Indenture shall not apply to, and have no force and effect with respect to, the Notes and any reference to
Section 6.02 of the Base Indenture with respect to the Notes shall be superseded by and references thereto shall be deemed to refer to this Section 6.02. 

If an Event of Default with respect to the Notes, other than an Event of Default pursuant to Section 6.01(ix) or (x) with respect to
the Company, occurs and is continuing, then in every case the Trustee or the Holders of not less than 25% in aggregate principal amount of the outstanding Notes may declare the principal amount of the Notes 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 portion) shall become immediately due and payable. If an Event of Default with respect to the Notes pursuant
to Sections 6.01(x) or (xi) occurs with respect to the Company, the principal amount of the Notes and accrued and unpaid interest, if any, shall automatically become immediately due and payable. 

At any time after such a declaration of acceleration with respect to the Notes has been made and before a judgment or decree for payment of
the money due based on such acceleration has been obtained by the Trustee as provided for in Section 6.03 of the Base Indenture, the Holders of a majority in principal amount of the outstanding Notes, 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 the Notes, other than the non-payment of the principal and interest, if any, of the Notes which have become due solely by such declaration
of acceleration, have been cured or waived as provided in Section 6.05 of this First Supplemental Indenture. No such rescission shall affect any subsequent default or impair any right consequent thereon. 

Section 6.03 Additional Interest. 

Notwithstanding anything else in this Indenture to the contrary, if the Company so elects, the sole remedy under the Indenture for an Event of
Default relating to (i) the Company’s failure to file with the Trustee pursuant to Section 314(a)(1) of the TIA any documents or reports that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of
the Exchange Act or (ii) the Company’s failure to comply with its reporting obligations to the Trustee and the Commission, pursuant to Section 9.01, will, for the first 270 days after the occurrence of such an Event of Default,
consist exclusively of the right to receive additional interest on the Notes at an annual rate equal to 0.25% of the aggregate principal amount of the Notes for the first 90 days after the occurrence of such an Event of Default and at an annual rate
equal to 0.50% of the aggregate principal amount of the Notes from the 91st day to, but not including, the 271st day thereafter (or, if applicable, the earlier date on which the Event of Default relating to the reporting obligations is cured or
waived) (“Additional Interest”). Any 

  
 32 

 
such Additional Interest will be payable in the same manner and on the same dates as the stated interest payable on the Notes. If the Event of Default is continuing on the 271st day after an
Event of Default relating to a failure to comply with the reporting obligations described above first occurs, the Notes will be subject to acceleration as provided in Section 6.02 of this First Supplemental Indenture. The provisions of this
Indenture described in this paragraph will not affect the rights of Holders of Notes in the event of the occurrence of any other Events of Default. 

In order to elect to pay Additional Interest as the sole remedy during the first 270 days after the occurrence of an Event of Default relating
to the Company’s failure to comply with the reporting obligations set forth in clauses (i) or (ii) of the immediately preceding paragraph, the Company must notify in writing all Holders and the Trustee and Paying Agent of such
election on or before the Close of Business on the fifth Business Day prior to the date on which such Event of Default would otherwise occur. Upon the Company’s failure to timely give such notice or pay Additional Interest, the Notes will be
immediately subject to acceleration as provided in Section 6.02 of this First Supplemental Indenture. 
 Section 6.04
Suits. 
 Section 6.07 of the Base Indenture shall not apply to, and have no force and effect with respect to, the Notes and any
reference to Section 6.07 of the Base Indenture with respect to the Notes shall be superseded by and references thereto shall be deemed to refer to this Section 6.04. 

No Holder of the Notes shall have any right to institute any proceeding, judicial or otherwise, with respect to the Base Indenture or First
Supplemental 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 Notes; 
 (b) the Holders of at least 25%
in aggregate principal amount of the outstanding Notes 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 shall have offered indemnity to the Trustee satisfactory to it against the costs, expenses and liabilities to be
incurred 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 aggregate principal amount of the outstanding Notes; 
 it being understood and intended
that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of the Base Indenture or the First Supplemental Indenture to affect, disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under the Base Indenture or First Supplemental Indenture, except in the manner herein provided and for the equal and ratable benefit of
all Holders. 

  
 33 

 However, the limitations of this Section 6.04 do not apply to a suit instituted by a Holder
for the enforcement of payment of the principal of or interest on any Note on or after the applicable due date, the right to convert the Note or to receive the consideration due upon conversion or the right of a Beneficial Owner to exchange its
beneficial interest in a global security representing Notes for a physical note if an Event of Default has occurred and is continuing, in each case, in accordance with this Indenture. 

Section 6.05 Waivers. 

Section 6.13 of the Base Indenture shall not apply to, and have no force and effect with respect to, the Notes and any reference to
Section 6.13 of the Base Indenture with respect to the Notes shall be superseded by and references thereto shall be deemed to refer to this Section 6.05. 

The Holders of not less than a majority of the aggregate principal amount of outstanding Notes may waive any default or Event of Default
unless: 
 (i) the Company fails to pay the principal of or any interest on any Note when due; 

(ii) the Company fails to deliver the consideration due upon conversion of any Note within the time period required by this
Indenture; or 
 (iii) the Company fails to comply with any of the provisions of this Indenture the modification of which
would require the consent of the Holder of each outstanding Note affected. 
 Upon any such waiver, such default shall cease to exist, and
any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. 

Section 6.06 Notice of Default. 

Section 7.05 of the Base Indenture shall not apply to, and have no force and effect with respect to, the Notes and any reference to
Section 7.05 of the Base Indenture with respect to the Notes shall be superseded by and references thereto shall be deemed to refer to this Section 6.06. 

Within 90 days after the occurrence and continuation of any default under this Indenture with respect to the Notes that is known to a
Responsible Officer of the Trustee, the Trustee shall transmit to all Holders notice of such default hereunder known to the Trustee, unless such default shall have been cured or waived; provided, however, that except in the case of a
default in the payment of the principal of or interest, if any, on any Note, or a default in the delivery of the consideration due upon conversion, the Trustee shall be protected in withholding such notice if and so long as a trust committee of
directors or Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interest of the Holders. For the purpose of this Section 6.06, the term “default” means any event which is, or
after notice or lapse of time or both would become, an Event of Default with respect to the Notes.

 Fluidigm Corporation, a Delaware corporation (herein called the “Company,” which term includes any
successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., or registered assigns, the principal sum of
$             Dollars, or such principal amount as shall be reflected in the books and records of the Trustee and the Depositary, on February 1, 2034, at the office or agency of

 REVERSE OF NOTE 

This Security is one of a duly authorized issue of securities of the Company (herein called the “Notes”), issued and to be issued in
one or more series under an Indenture, dated as of February 4, 2014 (herein called the “Base Indenture”), between the Company and U.S. Bank National Association, as Trustee, herein called the “Trustee” (which term includes
any successor trustee under the Indenture (as defined below)), to which Indenture (as defined below) and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, obligations,
duties and immunities thereunder of the Company, the Trustee and the Holders and of the terms upon which the Notes are, and are to be, authenticated and delivered. The terms of the Notes include the covenants and terms established by the First
Supplemental Indenture, dated as of February 4, 2014, among the Company and the Trustee (the “First Supplemental Indenture”, and as such First Supplemental Indenture amends and supplements the Base Indenture, the
“Indenture”), pursuant to the authority granted under the Indenture (such terms and covenants shall be referred to herein collectively with the terms and covenants set out in the Indenture that are applicable to the Notes as the
“Indenture Terms”). Defined terms used herein that are not otherwise defined shall have the meanings given such terms in the Indenture Terms. This Note is one of the series designated on the face hereof, which series has an initial
aggregate principal amount of $201,250,000. The Company may subsequently issue additional notes as part of this series of Notes under the Indenture; provided that if such additional notes are not fungible with the Notes initially issued under
the Indenture for U.S. federal income tax purposes, such additional Notes will have a separate CUSIP number. In the event of any conflict between the terms of the Notes and the terms of the Indenture, the terms of the Indenture shall control. 

1. Paying Agent and Registrar 

The Company initially appoints the Trustee as Paying Agent and Registrar. 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 or Paying Agent. The Company may also from time to time designate one or more co-registrars or additional paying 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 and a Paying Agent in each place so specified pursuant to Base Indenture Section 2.02. 

U.S. Bank National Association, the Trustee under the Indenture, or any banking institution serving as successor Trustee thereunder, in its
individual or any other capacity, may make loans to, accept deposits from and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates as if it were not Trustee. 

2. Indenture 
 The Company
will furnish to any Holder upon written request and without charge a copy of the Indenture. Requests may be made to: Fluidigm Corporation, 7000 Shoreline Court, Suite 100, South San Francisco, CA 94080, Attention: Chief Financial Officer. 

  

 3. Redemption 

The Notes are redeemable at certain times at the option of the Company in accordance with the Indenture prior to maturity. No sinking fund is
provided for the Notes and the Notes will not be subject to defeasance. 
 Subject to the Indenture Terms, the Notes called for Provisional
Redemption or Optional Redemption become due on the relevant Redemption Date. The Company shall give the Redemption Notice not less than 30 nor more than 60 calendar days immediately preceding the Redemption Date to each Holder to be redeemed at its

the Trustee shall select Notes to be redeemed in accordance with the procedures of the Depositary and the Indenture. 
 In the event of
redemption of this Note in part only, a new Note or Notes of this series in principal amount equal to the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof, subject to Section 3.01(d) of the
First Supplemental Indenture. 
 4. Repurchase at Option of Holders Upon a Fundamental Change 

Subject to the Indenture Terms, in the event of a Fundamental Change, each Holder of the Notes shall have the right, at the Holder’s
option, to require the Company to repurchase such Holder’s Notes including any portion thereof which is $1,000 in principal amount or any integral multiple thereof on the Fundamental Change Repurchase Date at a price payable in cash equal to
the Fundamental Change Repurchase Price. 
 5. Repurchase at Option of Holders Upon Specified Dates 

Subject to the Indenture Terms, on each specified Repurchase Date, each Holder of the Notes shall have the right, at the Holder’s option,
to require the Company to repurchase such Holder’s Notes including any portion thereof which is $1,000 in principal amount or any integral multiple thereof on the Repurchase Date at a price payable in cash equal to the Repurchase Price. 

6. Conversion  
 The Notes
shall be convertible into shares of Common Stock in accordance with Article V of the First Supplemental Indenture. To convert a Note, a Holder must satisfy the requirements of Section 5.04 of the First Supplemental Indenture. A Holder may

 Upon conversion
of a Note, the Holder thereof shall be entitled to receive shares of Common Stock payable upon conversion in accordance with Article V of the First Supplemental Indenture, at the Conversion Rate specified in the First Supplemental Indenture, as
adjusted from time to time as provided in the First Supplemental Indenture. 

  

 7. Events of Default 

The following constitute Events of Default: the Company fails to pay the principal of any Note when due; the Company fails to deliver the
Settlement Amount owing upon conversion of any Note when due, and such failure continues for five Business Days; the Company fails to pay any interest on any Note when due, and such failure continues for 30 calendar days; the Company fails to pay
the Redemption Price of any Note when due; the Company fails to pay the Repurchase Price or Fundamental Change Repurchase Price of any Note when due; the Company fails to provide timely notice of a Fundamental Change or a Make-Whole Fundamental
Change in accordance with the Indenture; the Company fails to perform any other covenant required of it in the Indenture (other than a covenant or agreement a default in whose performance or whose breach is specifically dealt with in the preceding
clauses of this sentence) and such failure continues for 60 calendar days after notice is given in accordance with the Indenture by the Trustee or Holders of not less than 25% in aggregate principal amounts of the outstanding Notes; (a) the
Company’s failure, or the failure of any of the Company’s Significant Subsidiaries to make any payment at maturity (after giving effect to any applicable grace period) of Indebtedness, in a principal amount in excess of $15.0 million and
continuance of such failure, or (b) the acceleration of Indebtedness of the Company or any of the Company’s Significant Subsidiaries in an amount in excess of $15.0 million because of a default with respect to such Indebtedness, unless
such Indebtedness is discharged or such acceleration has been cured, waived, rescinded or annulled, in either case within a period of 30 days after written notice to us given in accordance with the Indenture by the Trustee or Holders of not less
than 25% in aggregate principal amount of the outstanding Notes, provided, however, that if any such failure or acceleration referred to in (a) or (b) above shall cease or be cured, waived, rescinded or annulled, then the Event of Default
by reason thereof shall be deemed not to have occurred; and certain events of bankruptcy, insolvency or reorganization with respect to the Company or any of the Company’s Significant Subsidiaries as provided in the Indenture. If any Event of
Default occurs and is continuing (other than an Event of Default that is a result of bankruptcy, insolvency or reorganization of the Company as provided in the Indenture), the Trustee or the Holders of at least 25% in aggregate principal amount of
the outstanding Notes may declare the principal of all of the Notes to be due and payable immediately. If an event of default occurs that is a result of bankruptcy, insolvency or reorganization of the Company as provided in the Indenture, the
principal amount of the Notes and accrued and unpaid interest, if any, will automatically become due and payable in accordance with the Indenture. 

8. Amendments and Waivers 

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of
the Company and the rights of the Holders at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Notes at the time outstanding. Without the consent of or notice to any Holder, the
Indenture or the Notes may be amended or supplemented under the conditions specified in the Indenture, including to cure any ambiguity, omission, defect or inconsistency that does not materially adversely affect the Holders or to make any change
that does not adversely affect the rights of any Holder. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Notes at the time outstanding, on behalf of the Holders of all of the Notes,
to waive compliance by the Company 

  

 
with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holders shall be conclusive and binding upon such
Holder and upon all future Holders and of any Note issued upon the registration of transfer hereof or in exchange or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note. 

9. Company’s Payment Obligation 

No reference herein to the Indenture Terms and no provision of this Note or of the Indenture shall alter or impair the obligations of the
Company, which are absolute and unconditional, to pay the principal of and any interest on this Note at the times, places and rates, and in the coin or currency herein prescribed, and to perform the conversion obligations of the Company herein
prescribed. 
 10. Denominations, Transfer, Exchange 

The Notes are issuable only in registered form without coupons in minimum denominations of $1,000.00 and integral multiples of $1,000.00 in
excess thereof. As provided in the Indenture and subject to certain limitations set forth therein, Notes are exchangeable for a like aggregate principal amount of Notes and of like tenor of a different authorized denomination, as requested by the
Holder surrendering the same. 
 Where Notes are presented to the Registrar with a request to register a transfer or to exchange them for an
equal principal amount of Notes of this 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
Notes 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 the Indenture Terms). Neither the Company nor the Registrar shall be required
(a) to issue, register the transfer of, or exchange Notes for the period beginning at the opening of business fifteen days immediately preceding the delivery of a notice of redemption of Notes selected for redemption and ending at the close of
business on the day of such delivery, or (b) to register the transfer of or exchange Notes selected, called or being called for redemption as a whole or the portion being redeemed of any such Notes selected, called or being called for
redemption in part. 
 11. No Personal Liability of Directors, Officers, Employees and Shareholders 

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

  

 12. Persons Deemed Owners 

Prior to due presentment of this Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may
treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.
