	  	 	§	  	  	

 This Stipulation of Interest agreement is made and entered into this 20th day of August, 2012 (the
“Stipulation of Interest”), by and between ENERGY & EXPLORATION PARTNERS, LLC whose address is P.O. Box 471428, Fort Worth, Texas 76147-1376 (“ENEXP”), Halcón Energy Properties, Inc., a Delaware corporation, whose
address is 1100 Louisiana Street, Suite 6700, Houston, Texas 77002 (“Halcón”), and TDM HOLDING, LLC, a Texas Limited Liability Company with an address of 100 Throckmorton, Ste. 1700, Fort Worth, Texas 76102 (“TDM”).

 WHEREAS, ENEXP executed those certain Assignments of Overriding Royalty described in Exhibit A attached hereto (the
“ORRI Assignments”), that granted to TDM an overriding royalty interest those certain Oil, Gas, and Mineral Leases more particularly described in the ORRI Assignments (collectively, the “Subject Leases”); 

WHEREAS, each ORRI Assignment granted TDM with an undivided overriding royalty interest in the Subject Leases but certain of the ORRI
Assignments provided that the amount of said interest was subject to change, depending upon whether all other overriding royalty interests granted by Assignor created a total burden of greater than twenty-five percent (25%) of 8/8ths in any
given lease; 
 WHEREAS, by that certain Assignment, Bill of Sale and Conveyance dated April 19, 2012, recorded in Volume
1415, Page 132, Real Property Records of Grimes County, Texas, and Volume 1154, Page 9, Official Public Records of Madison County, Texas, and Volume 1021, Page 34, Official Public Records of Walker County, Texas, Assignor assigned to Halcón
Energy Properties, Inc. (the “Halcón”), an undivided sixty-five percent (65%) of 8/8ths interest in the Subject Leases and other oil, gas, and mineral leases (the “Halcón Assignment #1”); 

WHEREAS, by that certain Assignment, Bill of Sale and Conveyance dated April 19, 2012, recorded in Volume 1415, Page 107, Real
Property Records of Grimes County, Texas, and recorded in Volume 1154, Page 35, Official Public Records of Madison County, Texas, Assignor assigned to Halcón an undivided sixty-five percent (65%) of 8/8ths interest in the Subject Leases
and other oil, gas, and mineral leases (the “Halcón Assignment #2”); 

 WHEREAS, by that certain Assignment, Bill of Sale and Conveyance dated May 24, 2012,
recorded in Volume 1422, Page 245, Real Property Records of Grimes County, Texas, and Volume 1166, Page 154, Official Public Records of Madison County, Texas, and Volume 1028, Page 696, Official Public Records of Walker County, Texas, Assignor
assigned to Halcón an undivided sixty-five percent (65%) of 8/8ths interest in the Subject Leases and other oil, gas, and mineral leases (the “Halcón Assignment #3”); 

WHEREAS, by that certain Assignment, Bill of Sale and Conveyance dated May 24, 2012, recorded in Volume 1422, Page 255, Real
Property Records of Grimes County, Texas, and Volume 1166 Page 164, Official Public Records of Madison County, Texas, and Volume 1028, Page 706, Official Public Records of Walker County, Texas, Assignor assigned to Halcón an undivided
sixty-five percent (65%) of 8/8ths interest in the Subject Leases and other oil, gas, and mineral leases (the “Halcón Assignment #4”, and collectively, with Halcón Assignment #1, Halcón Assignment #2, and
Halcón Assignment #3, the “Halcón Assignments”); and 
 WHEREAS, ENEXP, Halcón, and TDM have
determined there is a need to fix the amount of the overriding royalty interest granted to TDM pursuant to the ORRI Assignments for the purpose of avoidance of all doubt and to stipulate TDM’s interest in the Subject Leases. 

NOW THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Assignor,
Halcón, and TDM hereby stipulate, mutually agree, and do hereby grant, assign, and convey, to the extent legally necessary to vest TDM with title to the overriding royalty interest in the Subject Leases in the amount set opposite its name in
the table shown on Exhibit B attached hereto. 
 The parties acknowledge that the Halcón Assignments provided
Halcón with a minimum net revenue interest of 65% of 75% of 8/8ths in the Subject Leases. Assignor hereby stipulates that, to the extent any of the Subject Leases have lease burdens in excess of 25% of 8/8ths, the amount by which such burdens
exceed 25% of 8/8ths shall be borne by Assignor’s working interest in said lease. 
 All other terms, conditions,
covenants, and agreements contained in the respective ORRI Assignments shall remain in force and effect. The parties hereto also agree that the terms of this Stipulation of Interest shall be binding upon the parties, their successors, heirs, assigns
and personal representatives. 
 This agreement may be executed in any number of counterparts, each of which shall be deemed an
original and all of which shall constitute but one and the same instrument.

 In Witness Whereof, this Stipulation of Interest is executed, agreed to, accepted, and
delivered by the parties as of the date first written above, but it is effective as of t he date of each lease comprising the Subject Leases.

DEFINITIONS AND INCORPORATION BY REFERENCE 

Section 1.01. Scope of First Supplemental Indenture. The changes, modifications and supplements to the Base Indenture
affected by this First Supplemental Indenture shall be applicable only with respect to, and shall only govern the terms of, the Notes, which shall, subject to Section 2.06, be limited to an aggregate principal amount not to exceed $396,750,000
Outstanding at any time, and shall not apply to any other Securities that may be issued under the Base Indenture unless a supplemental indenture with respect to such other Securities specifically incorporates such changes, modifications and
supplements. The provisions of this First Supplemental Indenture shall supersede any corresponding or inconsistent provisions in the Base Indenture with respect to the Securities. For all purposes under the Base Indenture, the Notes shall constitute
a single series of Securities, and with regard to any matter requiring the consent under the Base Indenture of Holders of multiple series of Securities voting together as a single class, the consent of Holders of the Notes voting as a separate class
shall also be required and the same threshold shall apply. 
 Section 1.02. Definitions. The terms defined in this
Section 1.02 (except as herein otherwise expressly provided or unless the context otherwise requires) for all purposes of the Indenture shall have the respective meanings specified in this Section 1.02 and, to the extent applicable, shall
supersede the definitions thereof in the Base Indenture. The words “herein,” “hereof,” “hereunder,” and words of similar import refer to this First Supplemental Indenture as a whole and not to any particular Article,
Section or other subdivision. The terms defined in this Article include the plural as well as the singular. References to “Article,” “Exhibit,” “Section” and “Attachment” refer to Articles, Exhibits, Sections
and Attachments, respectively, of or to this First Supplemental Indenture unless otherwise specified herein. All terms used in this First Supplemental Indenture and defined in the Base Indenture (but not otherwise defined herein) shall have the same
meanings as in the Base Indenture. All other terms used herein that are defined in the Trust Indenture Act, either directly or by reference therein, shall have the meanings assigned to them therein.

 2 

 “Base Conversion Rate” shall mean, initially, 60.4961 shares of Common
Stock (subject to adjustment as provided in Article 10). 
 “Base Indenture” shall have the meaning specified
in the first paragraph of this First Supplemental Indenture. 
 “Bid Solicitation Agent” means the Person
appointed by the Company to solicit bids for the Trading Price of the Notes in accordance with Section 10.01(b)(i). The Trustee shall initially act as the Bid Solicitation Agent.

federally chartered banking institutions in New York, New York are not required to be open. 
 “Cash

 “Change in Control” shall be
deemed to have occurred if any of the following occurs after the time after the Notes are originally issued: 

(a) any “person” or “group” (each as defined below) files a Schedule TO or any schedule, form or
report under the Exchange Act disclosing that such person or group has become the direct or indirect “beneficial owner” (as defined below) of shares of the Company’s Voting Stock representing 50% or more of the total voting power of
all outstanding classes of the Company’s Voting Stock or has the power, directly or indirectly, to elect a majority of the members of the Board of Directors (disregarding, solely for purposes of this subparagraph (a), the word
“either” and the phrase “or the executive or any other committee of that board duly authorized to act in respect hereof” in the definition of Board of Directors); provided that this clause (a) will not apply to a
merger of the Company (x) with or into a wholly owned subsidiary of a corporation that, immediately following the transaction or series of transactions, has a class of common stock listed and traded on The New York Stock Exchange, The NASDAQ
Global Market or The NASDAQ Global Select Market (or their respective successors) if immediately following the transaction or series of transactions the holders of the Common Stock immediately prior to the transaction are entitled to exercise,
directly or indirectly, 50% or more of the voting power of all shares of Capital Stock entitled to vote generally in the election of such directors of such parent corporation and (y) pursuant to which the Common Stock will be converted into
cash, securities or other property; 
 (b) the consummation of (A) any recapitalization, reclassification or
change of the Common Stock (other than changes resulting from a subdivision or combination) as a result of which the Common Stock would be converted into, or exchanged for, cash, securities or other property or assets; (B) any binding share
exchange, consolidation or merger of the Company pursuant to which the Common Stock will be converted into cash, securities or other property or assets; or (C) any 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, however, that a transaction described in clause (A) or
(B)

  
 3 

 
in which the holders of all classes of the Company’s Common Equity immediately prior to such transaction own, directly or indirectly, more than 50% of all classes of Common Equity of the

(c) the first day on which a majority of the members of the Board of Directors (disregarding, solely for purposes of this
subparagraph (c), the word “either” and the phrase “or the executive or any other committee of that board duly authorized to act in respect hereof” in the definition of Board of Directors) are not Continuing Directors; or

 (d) the Holders of the Company’s Capital Stock approve any plan or proposal for the liquidation or
dissolution of the Company (whether or not otherwise in compliance with the Indenture). 
 However, notwithstanding the foregoing, any
transaction described in clause (a) or (b) above will not constitute a “Change in Control” if at least 90% of the consideration received or to be received by the holders of the Common Stock, excluding cash payments for fractional
shares and cash payments made pursuant to dissenters’ appraisal rights, in connection with such transaction consists of shares of common stock listed and traded on The New York Stock Exchange, The NASDAQ Global Select Market or the NASDAQ
Global Market (or any of their respective successors), or will be so listed and traded immediately following the transaction, and, as a result of the transaction, the Notes become convertible into such consideration, subject to the provisions of
Section 10.02(a). 
 For purposes of this definition of “Change in Control,” (i) “person” or “group”
have the meanings given to them for purposes of Sections 13(d) and 14(d) of the Exchange Act or any successor provisions, and the term “group” includes any group acting for the purpose of acquiring, holding, voting or disposing of
securities within the meaning of Rule 13d-5(b)(1) under the Exchange Act, or any successor provision; (ii) a “beneficial owner” will be determined in accordance with Rule 13d-3 under the Exchange Act, as in effect on the date hereof;
and (iii) “beneficially own” and “beneficially owned” have meanings correlative to that of beneficial owner. 
 “Clause A Distribution” shall have the meaning specified in Section 10.04(c). 
 “Clause B Distribution” shall have the meaning specified in Section 10.04(c). 
 “Clause C Distribution” shall have the meaning specified in Section 10.04(c). 
 “close of business” means 5:00 p.m. (New York City time). 

“Closing Sale Price” of the Common Stock on any date means the closing per share sale price (or, if no closing sale
price is reported, the average of the bid and ask prices or, if more than one in either case, the average of the average bid and the average ask prices) at 4:00 p.m. (New York City time) on such date as reported in composite transactions for the
principal U.S. national or regional securities exchange on which the Common Stock is traded or, if the 

  
 4 

 
Common Stock is not listed on a U.S. national or regional securities exchange, as reported by OTC Markets Group, Inc. or a similar organization. If the Common Stock is not so quoted, the
“Closing Sale Price” shall be the average of the mid-point of the last bid and ask prices for the Common Stock on the relevant date from each of at least three nationally recognized independent investment banking firms selected by
the Company for this purpose. 
 “Combination Settlement” shall have the meaning specified in
Section 10.02(a). 
 “Common Equity” of any Person means Capital Stock of such Person that is generally
entitled (a) to vote in the election of directors of such Person or (b) if such Person is not a corporation, to vote or otherwise participate in the selection of the governing body, partners, managers or others that will control the
management or policies of such Person. 
 “Common Stock” means the common stock of the Company, par value $0.01

the proposed payment of such Defaulted Amounts and the special record date therefor to be mailed, first-class postage prepaid, to each Holder at its address as it appears in the Register, not less than 10 days prior to such special record date.

with Section 2.05. 
 (d) The Company or the Trustee may require a Holder to pay a sum sufficient to cover any tax or other

its Subsidiaries, Affiliates, agents or dealers or through a private or public tender or exchange offer or through counterparties to private agreements, including by 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 in accordance with Section 2.05. 

Section 2.07. Ranking. The obligations of the Company arising under or in connection with this Indenture and every
outstanding Note issued under this Indenture from time to time constitute and shall constitute a general unsecured obligation of the Company, ranking equal in right of payment to all other existing and future senior unsecured and unsubordinated
indebtedness of the Company and ranking senior in right of payment to any future indebtedness of the Company that is expressly made subordinate to the Notes by the terms of such indebtedness.

Section 3.01. Applicability of Article XII of the Base Indenture. Article XII of the Base Indenture shall not apply to the
Notes. Instead, the satisfaction and discharge provisions set forth in this Article 3 shall, with respect to the Notes, supersede in its entirety Article XII of the Base Indenture, and all references in the Base Indenture to Article XII thereof and

Section 3.02. Satisfaction and Discharge. This First Supplemental Indenture and the Base Indenture with respect to the Notes
shall upon request of the Company contained in an Officer’s Certificate cease to be of further effect, and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this First
Supplemental Indenture and the Base Indenture with respect to the Notes, when (a) (i) all Notes theretofore authenticated and delivered (other than (x) Notes which have been destroyed, lost or stolen and which have been replaced or
paid as provided in Section 3.07 of the Base Indenture and (y) Notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from
such trust, as provided in Section 6.03(e) of the Base Indenture) have been delivered to the Trustee for cancellation; or (ii) the Company has deposited with the Trustee or delivered to Holders, as applicable, after the Notes have become
due and payable, whether on the Maturity Date, any Repurchase Date, any Fundamental Change Repurchase Date, any Redemption Date, upon conversion or otherwise, cash, shares of Common Stock or a combination thereof, as applicable, solely to satisfy
the Company’s Conversion Obligation, sufficient to pay all of the Outstanding Notes and all other sums due and payable under the Indenture by the Company; and (b) the Company has delivered to the Trustee an Officer’s Certificate and

ARTICLE 4 

PARTICULAR COVENANTS OF THE COMPANY 

Section 4.01. Payment of Principal and Interest. The Company covenants and agrees that it will cause to be paid the principal

the Notes. 
 Section 4.02. Maintenance of Office or Agency for Conversion. The Company will maintain in the Place
of Payment an office or agency where the Notes may be surrendered for

time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such surrenders may be made or served at the Corporate Trust Office or the office or agency of the Trustee in
the Borough of Manhattan, The City of New York. 
 The Company may also from time to time designate as co-Registrars one or more
other offices or agencies where the Notes may be surrendered for conversion and may from time to time rescind such designations; provided that no such designation or rescission shall in any manner relieve the Company of its obligation to
maintain an office or agency in the Borough of Manhattan, The City of New York, for conversion. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other
office or agency. The term “Conversion Agent” includes any such additional or other offices or agencies, as applicable. 
 The Company hereby initially designates the Trustee as the Conversion Agent and the Corporate Trust Office and the office or agency of the Trustee in the Borough of Manhattan, The City of New York, each
shall be considered as one such office or agency of the Company for the aforesaid purposes.

required to be filed with the SEC, copies of any documents or reports that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act (giving effect to any grace period provided by Rule 12b-25 under the
Exchange Act). Any such document or report that the Company files with the SEC via the SEC’s EDGAR system (or any successor system thereto) shall be deemed to be filed with the Trustee for purposes of this Section 4.05(a) at the time such
documents are filed via the EDGAR system (or any successor system thereto). 
 (b) Delivery of the reports and documents
described in subsection (a) above to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained
therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to conclusively rely on an Officer’s Certificate). 

  
 18 

 Section 4.06. Stay, Extension and Usury Laws. The Company covenants (to the
extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law that would prohibit or forgive the Company from
paying all or any portion of the principal of or interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that may affect the covenants or the performance of the Indenture; and the Company (to the
extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will
suffer and permit the execution of every such power as though no such law had been enacted. 
 Section 4.07. Compliance
Certificate; Statements as to Defaults. (a) Sections 6.05 and 6.07 of the Base Indenture shall not apply to the Notes. The provisions set forth in this Section 4.07 shall, with respect to the Notes, supersede in their entirety Sections
6.05 and 6.07 of the Base Indenture. All references in the Base Indenture to Section 6.05 thereof shall, with respect to the Notes, be deemed to be references to this Section 4.07. 

(b) The Company shall deliver to the Trustee (i) within 120 days after the end of each fiscal year of the Company (beginning with
the fiscal year ending on December 31, 2012), a certificate from the principal executive officer, principal financial officer or principal accounting officer indicating whether the signer thereof knows of any Default that occurred during the
previous year and is continuing and whether the Company, to such officer’s knowledge, is in default in the performance or observance of any of the terms, provisions and conditions of the Indenture and (ii) within 30 days after obtaining

 ARTICLE 6 
 DEFAULTS AND REMEDIES 

Section 6.01. Applicability of Article VII of the Base Indenture. Article VII of the Base Indenture shall not apply to the
Notes. Instead, the provisions set forth in this Article 6 shall, with respect to the Notes, supersede in their entirety Article VII of the Base Indenture, and all references in the Base Indenture to Article VII thereof and the provisions therein,
as the case may be, shall, with respect to the Notes, be deemed to be references to this Article 6 and the provisions set forth in this Article 6, respectively. 
 Section 6.02. Events of Default. The following events shall be “Events of Default” with respect to the Notes: 

(a) failure by the Company to pay the principal of any Note when due on the Maturity Date, upon Optional Redemption, upon any required
repurchase of the Notes pursuant to Article 11, upon declaration of acceleration or otherwise; 
 (b) failure by the Company to
pay or deliver, as the case may be, the consideration due upon conversion of any Note (including any Additional Shares) when due and such failure continues for a period of five Business Days; 

(c) failure by the Company to pay any interest on any Note when due if such failure continues for 30 days; 

(d) failure by the Company to timely provide a Fundamental Change Repurchase Right Notice in accordance with Section 11.02(c) or
timely provide notice of a specified corporate event in accordance with Section 10.01(b)(ii) or Section 10.01(b)(iii) if such failure continues for a period of five Business Days; 

(e) failure by the Company to comply with its obligations under Article 9; 

(f) failure by the Company for 60 days after written notice from the Trustee or the Holders of at least 25% in principal amount of the
Notes then Outstanding has been received by the Company to comply with any of its other agreements contained in the Notes or the Indenture; 
 (g) any indebtedness for money borrowed by the Company or any Significant Subsidiary in an outstanding principal amount in excess of $10 million (or its foreign currency equivalent) is not paid at final
maturity or is accelerated and such indebtedness is not discharged, or such default in payment or acceleration is not cured or rescinded, within 30 days after written notice as provided in this First Supplemental Indenture; 

(h) failure by the Company or any Significant Subsidiary to pay one or more final and non-appealable judgments entered by a court or
courts of competent jurisdiction, the aggregate uninsured or unbonded portion of which is in excess of $10 million (or its foreign currency equivalent), if the judgments are not paid, discharged or stayed within 60 days; 

  
 20 

 (i) the Company or any Significant Subsidiary shall commence a voluntary case or other
proceeding seeking liquidation, reorganization or other relief with respect to the Company or any such Significant Subsidiary or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of
a trustee, receiver, liquidator, custodian or other similar official of the Company or any such Significant Subsidiary or any substantial part of its property, or shall consent to any such relief or to the appointment of or taking possession by any
such official in an involuntary case or other proceeding commenced against it, or shall make a general assignment for the benefit of creditors, or shall fail generally to pay its debts as they become due; or 

(j) an involuntary case or other proceeding shall be commenced against the Company or any Significant Subsidiary seeking liquidation,
reorganization or other relief with respect to the Company or such Significant Subsidiary or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator,
custodian or other similar official of the Company or such Significant Subsidiary or any substantial part of its property, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of 30 consecutive days.

 Section 6.03. Acceleration; Rescission and Annulment. If one or more Events of Default shall have occurred and be
continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any
administrative or governmental body), then, and in each and every such case (other than an Event of Default specified in Section 6.02(i) or Section 6.02(j) with respect to the Company), unless the principal of all of the Notes shall have
already become due and payable, either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then Outstanding determined in accordance with Section 7.01, by notice in writing to the Company (and to the Trustee if
given by Holders), may declare 100% of the principal of, and accrued and unpaid interest on, all the Notes to be due and payable immediately, and upon any such declaration the same shall become and shall automatically be immediately due and payable,
anything contained in the Indenture or in the Notes to the contrary notwithstanding. If an Event of Default specified in Section 6.02(i) or Section 6.02(j) with respect to the Company occurs, 100% of the principal of, and accrued and
unpaid interest, if any, on, all Notes shall become and shall automatically be immediately due and payable. 
 The immediately
preceding paragraph, however, is subject to the conditions that if, at any time after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been
obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay installments of accrued and unpaid interest upon all Notes and the principal of any and all Notes that shall have become due
otherwise than by acceleration (with interest on overdue installments of accrued and unpaid interest to the extent that payment of such interest is enforceable under applicable law, and on such principal at the rate borne by the Notes plus
one percent at such time) and amounts due to the Trustee pursuant to Section 11.01 of the Base 

  
 21 

 
Indenture, and if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) any and all existing Events of Default under the Indenture,
other than the nonpayment of the principal of and accrued and unpaid interest, if any, on Notes that shall have become due solely by such acceleration, shall have been cured or waived pursuant to Section 6.10, then and in every such case
(except as provided in the immediately succeeding sentence) the Holders of a majority in aggregate principal amount of the Notes then Outstanding, by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default with
respect to the Notes and rescind and annul such declaration and its consequences and such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of the Indenture; but no such
waiver or rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon. Notwithstanding anything to the contrary herein, no such waiver or rescission and annulment
shall extend to or shall affect any Default or Event of Default resulting from (i) the nonpayment of the principal (including the Redemption Price, the Fundamental Change Repurchase Price and the Repurchase Price on any Repurchase Date) of, or
accrued and unpaid interest on, any Notes or (ii) a failure to pay or deliver, as the case may be, the consideration due upon conversion of the Notes. 
 Section 6.04. Additional Interest. Notwithstanding anything in the Indenture or in the Notes to the contrary, if the Company so elects, the sole remedy 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 SEC pursuant to Section 13 or 15(d) of the Exchange Act or
(ii) the Company’s failure to comply with its obligations as set forth in Section 4.05(a) shall, for the first 180 days after the occurrence of such an Event of Default, consist exclusively of the right to receive Additional Interest
on the Notes at a rate equal to 0.50% per annum of the aggregate principal amount of the Notes Outstanding to, but not including, the 181st day thereafter (or, if applicable, the earlier date on which such Event of Default is cured or waived).
Any such Additional Interest shall be payable in the same manner and on the same dates as the stated interest payable on the Notes. If such Event of Default is continuing on the 181st day after an Event of Default described in either clause
(i) or clause (ii) above first occurs, the Notes will be subject to acceleration as provided in Section 6.03. In the event the Company does not elect to pay Additional Interest following an Event of Default in accordance with this
Section 6.04 or the Company elected to make such payment but does not pay the Additional Interest when due, the Notes shall be subject to acceleration as provided in Section 6.03. The provisions of this Section 6.04 will not affect
the rights of Holders in the event of the occurrence of any other Event of Default. 
 In order to elect to pay Additional
Interest as the sole remedy during the first 180 days after the occurrence of an Event of Default described in the immediately preceding paragraph, the Company must notify all Holders of the Notes, the Trustee and the Paying Agent of such election
on or before the close of business on the date on which such Event of Default occurs. Upon the failure to timely give such notice, the Notes shall be immediately subject to acceleration as provided in Section 6.03. 

Section 6.05. Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause (a) or (c) of
Section 6.02 shall have occurred, the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of the Notes, the whole 

  
 22 

 
amount then due and payable on the Notes for principal and interest, if any, with interest on any overdue principal and interest, if any, at the rate borne by the Notes plus one percent at
such time, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under Section 11.01 of the Base Indenture. If the Company shall fail 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 the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the Notes, wherever situated. 

In the event there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the
Notes under title 11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession
of the Company or such other obligor, the property of the Company or such other obligor, or in the event of any other judicial proceedings relative to the Company or such other obligor upon the Notes, or to the creditors or property of the Company
or such other obligor, the Trustee, irrespective of whether the principal of the Notes 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 pursuant to
the provisions of this Section 6.05, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal and accrued and unpaid interest, if any, in respect of
the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may deem 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 proceedings relative to the Company or any other obligor on the Notes, its or their creditors, or
its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due to the Trustee under Section 11.01 of the Base
Indenture; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Holders to make such payments to the Trustee, as administrative expenses, 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 reasonable compensation, expenses, advances and disbursements, including agents and counsel fees, and including
any other amounts due to the Trustee under Section 11.01 of the Base Indenture, incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements out of the
estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property that the Holders of the Notes may
be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise. 
 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 such Holder 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. 

  
 23 

 All rights of action and of asserting claims under the Indenture, or under any of the Notes,
may be enforced by the Trustee without the possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or 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 Notes. 
 In any proceedings brought by the Trustee (and in any proceedings involving the interpretation of any provision
of the Indenture to which the Trustee shall be a party) the Trustee shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any Holders of the Notes parties to any such proceedings. 

In case the Trustee shall have proceeded to enforce any right under the Indenture and such proceedings shall have been discontinued or
abandoned because of any waiver pursuant to Section 6.10 or any rescission and annulment pursuant to Section 6.03 or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the
Holders, and the Trustee shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Holders, and the Trustee shall
continue as though no such proceeding had been instituted. 
 Section 6.06. Application of Monies Collected by
Trustee. Any monies collected by the Trustee pursuant to this Article 6 with respect to the Notes shall be applied in the following order, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the
several Notes, and stamping thereon 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 11.01 of the Base Indenture; 

Second, in case the principal of the Outstanding Notes shall not have become due and be unpaid, to the payment of interest on, and
any cash due upon conversion of, the Notes in default in the order of the date due of the payments of such interest and cash due upon conversion, as the case may be, with interest (to the extent that such interest has been collected by the Trustee)
upon such overdue payments at the rate borne by the Notes at such time plus one percent, such payments to be made ratably to the Persons entitled thereto; 
 Third, in case the principal of the Outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment of the whole amount (including, if applicable, the payment of
the Fundamental Change Repurchase Price, the Repurchase Price, the Redemption Price and any cash due upon conversion) then owing and unpaid upon the Notes for principal and interest, if any, with interest on the overdue principal and, to the extent
that such interest has been collected by the Trustee, upon overdue installments of interest at the rate borne 

  
 24 

 
by the Notes at such time plus one percent, and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment of such
principal (including, if applicable, the Fundamental Change Repurchase Price, the Repurchase Price, the Redemption Price and the cash due upon conversion) and interest without preference or priority of principal over interest, or of interest over
principal or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such principal (including, if applicable, the Fundamental Change Repurchase Price, the Repurchase
Price, the Redemption Price and any cash due upon conversion) and accrued and unpaid interest; and 
 Fourth, to the
payment of the remainder, if any, to the Company. 
 Section 6.07. Proceedings by Holders. Except to enforce the
right to receive payment of principal (including, if applicable, the Fundamental Change Repurchase Price, the Repurchase Price and the Redemption Price) or interest when due, or the right to convert Notes and receive payment or delivery of the
consideration due upon conversion, no Holder of any Note shall have any right by virtue of or by availing of any provision of the Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to the
Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any other remedy hereunder, unless: 
 (a) such Holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as herein provided; 

(b) Holders of at least 25% in aggregate principal amount of the Notes then Outstanding shall have made written request upon the Trustee
to institute such action, suit or proceeding in its own name as Trustee hereunder; 
 (c) such Holders shall have offered to the
Trustee reasonable indemnity against any loss, liability or expense to be incurred therein or thereby; 
 (d) the Trustee for 60
days after its receipt of such notice, request and offer of such indemnity, shall have neglected or refused to institute any such action, suit or proceeding; and 
 (e) no direction that is inconsistent with such written request shall have been given to the Trustee by the Holders of a majority of the aggregate principal amount of the Notes then Outstanding within
such 60-day period pursuant to Section 6.10, 
 it being understood and intended, and being expressly covenanted by the taker and Holder of
every Note with every other taker and Holder and the Trustee that no one or more Holders shall have any right in any manner whatever to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under the
Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders (except as otherwise provided herein). For the protection and enforcement of this Section 6.07, each and every Holder and the Trustee
shall be entitled to such relief as can be given either at law or in equity. 

  
 25 

 Notwithstanding any other provision of the Indenture and any provision of any Note, the
right of any Holder to convert its Notes or receive payment or delivery, as the case may be, of (x) the principal (including the Repurchase Price, the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of,
(y) accrued and unpaid interest, if any, on, and (z) the consideration due upon conversion of, such Note, on or after the respective due dates expressed or provided for in such Note or in the Indenture, or to institute suit for the
enforcement of any such payment or delivery, as the case may be, on or after such respective dates against the Company shall not be impaired or affected without the consent of such Holder. 

Section 6.08. Proceedings by Trustee. In case of an Event of Default, the Trustee may in its discretion proceed to protect
and enforce the rights vested in it by the Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise,
whether for the specific enforcement of any covenant or agreement contained in the Indenture or in aid of the exercise of any power granted in the Indenture, or to enforce any other legal or equitable right vested in the Trustee by the Indenture or
by law. 
 Section 6.09. Remedies Cumulative and Continuing. Except as provided in subsections (d) and
(e) of Section 3.07 of the Base Indenture, all powers and remedies given by this Article 6 to the Trustee or to the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers
and remedies available to the Trustee or the Holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in the Indenture, and no delay or omission of the Trustee or
of any Holder of any of the Notes to exercise any right or power accruing upon any Default or Event of Default shall impair any such right or power, or shall be construed to be a waiver of any such Default or Event of Default or any acquiescence
therein; and, subject to the provisions of Section 6.07, every power and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or
by the Holders. 
 Section 6.10. Direction of Proceedings and Waiver of Defaults by Majority of Holders. The Holders
of a majority of the aggregate principal amount of the Notes at the time Outstanding determined in accordance with Section 7.01 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 Notes; provided, however, that (a) such direction shall not be in conflict with any rule of law or with the Indenture, and (b) the Trustee
may take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may refuse to follow any direction that it determines is unduly prejudicial to the rights of any other Holder or that would involve the
Trustee in personal liability. The Holders of a majority in aggregate principal amount of the Notes at the time Outstanding determined in accordance with Section 7.01 may on behalf of the Holders of all of the Notes waive any past Default or
Event of Default hereunder and its consequences except (i) a default in the payment of accrued and unpaid interest, if any, on, or the principal (including any Fundamental Change Repurchase Price, the Redemption Price or the Repurchase Price)
of, the Notes when due that has not been cured pursuant to the provisions of Section 6.01, (ii) a failure by the Company to pay or deliver, as the case may be, the consideration due upon conversion of the Notes or (iii) a default in
respect of a covenant or provision hereof which under Article 8 

  
 26 

 
cannot be modified or amended without the consent of each Holder of an Outstanding Note affected. Upon any such waiver the Company, the Trustee and the Holders of the Notes shall be restored to
their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as
permitted by this Section 6.10, said Default or Event of Default shall for all purposes of the Notes and the Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or
Event of Default or impair any right consequent thereon. 
 Section 6.11. Notice of Defaults. The Trustee shall,
within 90 days after the occurrence and continuance of a Default of which a Responsible Officer has actual knowledge, mail to all Holders as the names and addresses of such Holders appear upon the Register, notice of all Defaults known to a
Responsible Officer, unless such Defaults shall have been cured or waived before the giving of such notice; provided that, notwithstanding Section 315(b) of the Trust Indenture Act and except in the case of a Default in the payment of
the principal of (including the Repurchase Price, the Redemption Price and the Fundamental Change Repurchase Price, if applicable), or accrued and unpaid interest on, any of the Notes or a Default in the payment or delivery of the consideration due
upon conversion, the Trustee shall be protected in withholding such notice if and so long as a committee of Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders.

 Section 6.12. Undertaking to Pay Costs. All parties to the Indenture agree, and each Holder of any Note by its
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 the Indenture, or in any suit against the Trustee for any action taken or omitted by it
as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party
litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section 6.12 (to the extent permitted by law) shall not apply 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 Notes at the time Outstanding determined in accordance with Section 7.01, or to any suit
instituted by any Holder for the enforcement of the payment of the principal of or accrued and unpaid interest, if any, on any Note (including, but not limited to, the Fundamental Change Repurchase Price and Repurchase Price with respect to the
Notes being repurchased as provided in the Indenture or the Redemption Price with respect to the Notes being redeemed as provided in the Indenture) on or after the due date expressed or provided for in such Note or to any suit for the enforcement of
the right to convert any Note in accordance with the provisions of Article 10.

 ARTICLE 7 
 CONCERNING THE HOLDERS 

Section 7.01. Company-Owned Notes Disregarded. Subject to Section 2.06, in determining whether the Holders of the
requisite aggregate principal amount of Notes have concurred in any direction, consent, waiver or other action under the Indenture, Notes that are owned by the Company, by any Subsidiary thereof or by any Person directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company or any Subsidiary thereof shall be disregarded and deemed not to be Outstanding for the purpose of any such determination; provided that for the purposes of determining
whether the Trustee shall be protected in relying on any such direction, consent, waiver or other action only Notes that a Responsible Officer of the Trustee knows are so owned shall be so disregarded. Notes so owned that have been pledged in good
faith may be regarded as Outstanding for the purposes of this Section 7.01 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to so act with respect to such Notes and that the pledgee is not the Company,
a Subsidiary thereof or a Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or a Subsidiary thereof. In the case of a dispute as to such right, any decision by the Trustee taken
upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officer’s Certificate listing and identifying all Notes, if any, known by the Company to be
owned or held by or for the account of any of the above described Persons; and, subject to Section 11.02 and Section 11.08 of the Base Indenture, the Trustee shall be entitled to accept such Officer’s Certificate as conclusive
evidence of the facts therein set forth and of the fact that all Notes not listed therein are Outstanding for the purpose of any such determination. 
 ARTICLE 8 
 SUPPLEMENTAL INDENTURES 

Section 8.01. Applicability of Section 14.01 and Section 14.02(a) of the Base Indenture. Section 14.01 and
Section 14.02(a) of the Base Indenture shall not apply to the Notes. References in the Base Indenture to any supplemental indenture authorized under Article XIV, Section 14.01 or Section 14.02, as the case may be, of the Base
Indenture shall be deemed to include any supplemental indenture authorized under Article 8, Section 8.02 or Section 8.03, as the case may be, of this First Supplemental Indenture.

 (b) to cure any manifest error; 

  
 28 

 (c) to cure any ambiguity, defect or inconsistency, or make any other change that does not
adversely affect the rights of any Holder (and any amendment or supplement made solely to conform the provisions of the Indenture and the Notes to the description of the Indenture and the Notes contained in the “Description of the Notes”
section of the Prospectus Supplement will be deemed not to adversely affect the rights of any Holder); 
 (d) to provide for the
assumption by a Successor Company of the obligations of the Company under this Indenture pursuant to Article 9; 
 (e) to add
guarantees with respect to the Notes; 
 (f) to secure the Notes;

supplemental indenture that affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise. 

Any supplemental indenture authorized by the provisions of this Section 8.02 may be executed by the Company and the Trustee without
the consent of, or notice to, the Holders of any of the Notes at the time outstanding, notwithstanding any of the provisions of Section 8.03. 
 Section 8.03. Supplemental Indentures with Consent of Holders. With the consent (evidenced as provided in Article VIII of the Base Indenture) of the Holders of at least a majority of the
aggregate principal amount of the Notes then Outstanding (determined in accordance with Article VIII of the Base Indenture and Article 7 of this First Supplemental Indenture and including, without limitation, consents obtained in connection with a
repurchase of, or tender or exchange offer for, Notes), the Company, when authorized by a Board Resolution and the Trustee, at the Company’s expense, may from time to time and at any time enter into an amendment or amendments or indenture or

(f) modify the provisions of Article 11 in a manner adverse to Holders; 

(g) adversely affect the rights of Holders to convert Notes; 
 (h) change the ranking of the Notes; or

ARTICLE 9 

CONSOLIDATION, MERGER, SALE, ASSIGNMENT, CONVEYANCE
AND LEASE 
 Section 9.01. Applicability of Section 6.04 of the Base Indenture.
Section 6.04 of the Base Indenture shall not apply to the Notes. The provisions set forth in this Article 9 shall, with respect to the Notes, supersede in their entirety Section 6.04 of the Base Indenture, and all references in the Base
Indenture to Section 6.04 thereof shall, with respect to the Notes, be deemed to be references to this Article 9. 

Section 9.02. Company May Consolidate, Etc. on Certain Terms. The Company shall not consolidate with, enter into a binding
share exchange with, or merge with or into, another Person or sell, assign, convey, transfer, lease or otherwise dispose of its properties and assets substantially as an entirety to any successor Person, unless: 

(a) the resulting, surviving or transferee Person (the “Successor Company”), if not the Company, shall be a corporation
organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, and the Successor Company (if not the Company) shall expressly assume, by supplemental indenture all of the obligations of the
Company under the Notes and the Indenture; 
 (b) immediately after giving effect to such transaction, no Default or Event of
Default shall have occurred and be continuing under the Indenture; and 
 (c) the Company shall have delivered to the Trustee an
Officer’s Certificate and an Opinion of Counsel pursuant to Section 9.04. 

  
 30 

 For purposes of this Section 9.02, the sale, assignment, conveyance, transfer, lease or
other disposition of the properties and assets of one or more Subsidiaries of the Company substantially as an entirety to another Person, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute the
properties and assets of the Company substantially as an entirety on a consolidated basis, shall be deemed to be the sale, assignment, conveyance, transfer, lease or other disposition of the properties and assets of the Company substantially as an
entirety to another Person. 
 Section 9.03. Successor Corporation to Be Substituted. In case of any such
consolidation, binding share exchange, merger, sale, assignment, conveyance, transfer, lease or other disposition and upon the assumption by the Successor Company (if not the Company), by supplemental indenture, executed and delivered to the Trustee
and satisfactory in form to the Trustee, of the due and punctual payment of the principal of and accrued and unpaid interest on all of the Notes, the due and punctual delivery or payment, as the case may be, of any consideration due upon conversion
of the Notes and the due and punctual performance of all of the covenants and conditions of the Indenture to be performed by the Company, such Successor Company (if not the Company) shall succeed to and, except in the case of a lease of the
Company’s properties and assets substantially as an entirety, shall be substituted for the Company, with the same effect as if it had been named herein as the party of the first part. Such Successor Company thereupon may cause to be signed, and
may issue either in its own name or in the name of the Company any or all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such Successor Company instead
of the Company and subject to all the terms, conditions and limitations in the Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that previously shall have been signed and
delivered by the Officers of the Company to the Trustee for authentication, and any Notes that such Successor Company thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects
have the same legal rank and benefit under the Indenture as the Notes theretofore or thereafter issued in accordance with the terms of the Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any
such consolidation, binding share exchange, merger, sale, assignment, conveyance, transfer or other disposition (but not in the case of a lease), upon compliance with this Article 9 the Person named as the “Company” in the first paragraph
of the Indenture (or any successor that shall thereafter have become such in the manner prescribed in this Article 9) may be dissolved, wound up and liquidated at any time thereafter and, except in the case of a lease, such Person shall be released
from its liabilities as obligor and maker of the Notes and from its obligations under the Indenture and the Notes. 
 In case of
any such consolidation, binding share exchange, merger, sale, conveyance, assignment, transfer, lease or other disposition, such changes in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as may be
appropriate. 
 Section 9.04. Opinion of Counsel to Be Given to Trustee. No consolidation, binding share exchange,
merger, sale, conveyance, assignment, transfer, lease or other disposition shall 

  
 31 

 
be effective unless the Trustee shall receive an Officer’s Certificate and an Opinion of Counsel stating that any such consolidation, binding share exchange, merger, sale, conveyance,
assignment, transfer, lease or other disposition and any such assumption and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, complies with the provisions of this Article 9. 

ARTICLE 10 

CONVERSION OF NOTES 
 Section 10.01. Conversion Privilege. (a) Subject to and upon compliance with the provisions of this Article 10, each Holder of a Note shall have the right, at such Holder’s option,
to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple thereof) of such Note (i) subject to satisfaction of the conditions described in Section 10.01(b), at any time prior to the
close of business on the Business Day immediately preceding the Maturity Date under the circumstances and during the periods set forth in Section 10.01(b), and (ii) irrespective of the conditions described in Section 10.01(b), during
the period from, and including, July 15, 2019 to, but excluding, October 15, 2019, and during the period from, and including, July 15, 2032 to, but excluding, the Maturity Date, in each case, at the Applicable Conversion Rate per
$1,000 principal amount of Notes (subject to, and in accordance with, the settlement provisions of Section 10.02, the “Conversion Obligation”). 
 (b) (i) If the Trading Price per $1,000 principal amount of the Notes on each Trading Day during any ten consecutive Trading Day period (the “Measurement Period”) was less than 97% of the
product of the Closing Sale Price of the Common Stock on each such Trading Day, and the Applicable Conversion Rate (calculated, for purposes of this subsection (b)(i), as if the Daily VWAP for such Trading Day were the Daily VWAP for each
Trading Day in the Conversion Period used to calculate the Applicable Conversion Rate) on each such Trading Day (the “Trading Price Condition”), a Holder may surrender Notes for conversion at any time during the following five
Business Days. The Trading Prices shall be determined by the Bid Solicitation Agent pursuant to this subsection (b)(i) and the definition of Trading Price set forth in this First Supplemental Indenture. The Company shall provide written notice to
the Bid Solicitation Agent of the three independent nationally recognized securities dealers selected by the Company pursuant to the definition of Trading Price, along with appropriate contact information for each. The Bid Solicitation Agent shall
have no obligation to determine the Trading Price per $1,000 principal amount of the Notes unless the Company has requested such determination in writing, and the Company shall have no obligation to make such request unless a Holder provides the
Company and the Bid Solicitation Agent with reasonable evidence that the Trading Price per $1,000 principal amount of the Notes on any Trading Day would be less than 97% of the product of the Closing Sale Price of the Common Stock on such Trading
Day, and the Applicable Conversion Rate (calculated as described above). At such time, the Company shall instruct the Bid Solicitation Agent to determine the Trading Price per $1,000 principal amount of the Notes beginning such Trading Day
until the Trading Price per $1,000 principal amount of the Notes is greater than or equal to 97% of the product of the Closing Sale Price of the Common Stock, and the Applicable Conversion Rate. Once the Trading Price Condition has been met,
the Company shall so notify the Holders, the Trustee and the Conversion Agent (if 

  
 32 

 
other than the Trustee). If, at any time after the Trading Price Condition has been met, the Trading Price per $1,000 principal amount of the Notes is greater than or equal to 97% of the product
of the Closing Sale Price of the Common Stock, and the Applicable Conversion Rate (calculated as described above), the Company shall so notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee). If the Company does
not instruct the Bid Solicitation Agent to obtain bids when required, or if the Company instructs the Bid Solicitation Agent to obtain bids and the Bid Solicitation Agent fails to obtain such bids when required, then, in either case, the Trading
Price per $1,000 principal amount of the Notes shall be deemed to be less than 97% of the product of the Closing Sale Price of the Common Stock, and the Applicable Conversion Rate (calculated as described above) on each Trading Day of such
failure. 
 (ii) If the Company elects to: 

(A) issue to all or substantially all holders of the Common Stock any rights, options or warrants entitling them, for a
period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of the Common Stock at a price per share that is less than the Closing Sale Price of the Common Stock on the Trading Day
immediately preceding the announcement date of such issuance; or 
 (B) distribute to all or substantially all
holders of the Common Stock the Company’s property, assets, securities or rights, options or warrants to purchase securities of the Company, which distribution has a per share value, as reasonably determined by the Board of Directors, exceeding
10% of the Closing Sale Price of the Common Stock as of the Trading Day immediately preceding the announcement date of such distribution, 

then, in either case, the Company shall notify all Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee) at least 30
Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution. Once the Company has given such notice, Holders may surrender Notes for conversion at any time until the earlier of (1) the close of business on the
Business Day immediately preceding the Ex-Dividend Date for such issuance or distribution and (2) the Company’s announcement that such issuance or distribution will not take place, in each case, even if the Notes are not otherwise
convertible at such time. Holders may not exercise this right (and need not be given advance notice of the issuance or distribution) if they will participate, at the same time and upon the same terms as holders of the Common Stock and solely as a
result of holding the Notes, in the issuance or distribution described above without having to convert their Notes as if they held a number of shares of Common Stock, for each $1,000 principal amount of their Notes, equal to the Applicable
Conversion Rate (calculated as if the Daily VWAP for each Trading Day in the Conversion Period used to calculate the Applicable Conversion Rate were the Daily VWAP for the Trading Day immediately preceding the Ex-Dividend Date of such issuance or
distribution). 
 (iii) If a transaction or event that constitutes a Fundamental Change or a Make-Whole
Adjustment Event occurs, regardless of whether a Holder has the right to require the Company to repurchase the Notes pursuant to Section 11.02, or if the Company is a party to a consolidation, merger, binding share exchange, or a sale,
assignment, 

  
 33 

 
conveyance, transfer, lease or other disposition of all or substantially all of its assets, in each case, pursuant to which the Common Stock would be converted into cash, securities or other
assets, the Notes may be surrendered for conversion at any time on or after the date that is 30 Scheduled Trading Days prior to the anticipated effective date of such transaction (or, if later, the Business Day after the Company gives notice of such
transaction) until 40 Trading Days after the actual effective date of such transaction or, if such transaction also constitutes a Fundamental Change, until the related Fundamental Change Repurchase Date. The Company shall notify Holders, the Trustee
and the Conversion Agent (if other than the Trustee) (i) as promptly as practicable following the date the Company publicly announces such transaction but in no event less than 30 Scheduled Trading Days prior to the anticipated effective date
of such transaction or (ii) if the Company does not have knowledge of such transaction at least 30 Scheduled Trading Days prior to the anticipated effective date of such transaction, within one Business Day of the date upon which the Company
receives notice, or otherwise becomes aware, of such transaction, but in no event later than the actual effective date of such transaction; provided that in no event shall the Company be required to provide such notice to the Holders, the
Trustee and the Conversion Agent (if other than the Trustee) before the earlier of such time as the Company or its Affiliates (a) have publicly disclosed or acknowledged the circumstances giving rise to such transaction or (b) are required
to publicly disclose under applicable law or the rules of any stock exchange on which the Common Stock is then listed the circumstances giving rise to such transaction. The Company shall use its commercially reasonable efforts to make such
determination in time to deliver such notice no later than 30 Scheduled Trading Days prior to the anticipated effective date of such transaction. 
 (iv) Holders may surrender Notes for conversion during any calendar quarter commencing after the calendar quarter ending on December 31, 2012 (and only during such calendar quarter), if the Closing
Sale Price of the Common Stock, for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on the last Trading Day of the immediately preceding calendar quarter, is greater than 135% of the Base
Conversion Price on each such Trading Day. The Conversion Agent, on behalf of the Company, shall determine at the beginning of each calendar quarter commencing after December 31, 2012 whether the Notes may be surrendered for conversion in
accordance with this clause (iv) and shall notify the Company and the Trustee (if the Conversion Agent is other than the Trustee) if the Notes become convertible in accordance with this clause (iv). 

(v) If the Company calls any or all of the Notes for redemption pursuant to Article 12, Holders may surrender their Notes
for conversion at any time prior to the close of business on the Business Day immediately preceding the Redemption Date, even if the Notes are not otherwise convertible at such time. After that time, the right to convert shall expire, unless the
Company defaults in the payment of the Redemption Price, in which case a Holder of Notes may convert the Notes until the Redemption Price has been paid or duly provided for. 

  
 34 

 Section 10.02. Conversion Procedure; Settlement Upon Conversion. 

(a) Subject to this Section 10.02, Section 10.03(b) and Section 10.07(a), upon conversion of any Note, the Company shall
pay or deliver, as the case may be, to the converting Holder, in respect of each $1,000 principal amount of Notes being converted, cash (“Cash Settlement”), shares of Common Stock, plus cash, if applicable, in lieu of any
fractional share of Common Stock in accordance with subsection (j) of this Section 10.02 (“Physical Settlement”) or a combination of cash and shares of Common Stock, plus cash, if applicable, in lieu of any
fractional share of Common Stock in accordance with subsection (j) of this Section 10.02 (“Combination Settlement”), at its election, as set forth in this Section 10.02. 

(i) All conversions for which the relevant Conversion Date occurs during the Maturity Conversion Period or occurs after
the Company’s issuance of a Redemption Notice with respect to the Notes and prior to the related Redemption Date (the “Redemption Period”), shall be settled using the same Settlement Method. 

(ii) Prior to the Maturity Conversion Period, except for any conversions for which the relevant Conversion Date occurs
during the Redemption Period, the Company shall use the same Settlement Method for all conversions occurring on a given Conversion Date, but the Company shall not have any obligation to use the same Settlement Method with respect to conversions that
occur on different Conversion Dates. 
 (iii) If, in respect of any Conversion Date that occurs other than during
the Maturity Conversion Period or any Redemption Period, in respect of any Conversion Date that occurs during the Maturity Conversion Period or in respect of any Conversion Date that occurs during any Redemption Period, as the case may be, the
Company elects to deliver a notice (the “Settlement Notice”) of the relevant Settlement Method in respect of Conversion Dates other than during the Maturity Conversion Period or any Redemption Period, in respect of Conversion Dates
that occur during the Maturity Conversion Period or in respect of Conversion Dates that occur during any such Redemption Period, as the case may be, the Company, through the Trustee and the Conversion Agent (if other than the Trustee), shall deliver
such Settlement Notice to converting Holders (x) in the case of Conversion Dates occurring during the Maturity Conversion Period, no later than the close of business on the 25th Scheduled Trading Day immediately preceding the Maturity Date,
(y) in the case of Conversion Dates occurring during any Redemption Period, in the relevant Redemption Notice and (z) in all other cases, no later than the close of business on the second Business Day immediately following the related
Conversion Date. If the Company does not elect a Settlement Method prior to the relevant deadline set forth in the immediately preceding sentence, the Company shall no longer have the right to elect Cash Settlement or Combination Settlement and the
Company shall be deemed to have elected Physical Settlement in respect of its Conversion Obligation. Any Settlement Notice shall specify the relevant Settlement Method and, in the case of an election of Combination Settlement, the relevant
Settlement Notice shall indicate the Specified Dollar Amount per $1,000 principal amount of Notes. If the Company delivers a Settlement Notice electing Combination Settlement in respect of its Conversion Obligation but does not indicate a Specified
Dollar Amount per $1,000 principal amount of Notes in such Settlement Notice, the Specified Dollar Amount per $1,000 principal amount of Notes shall be deemed to be $1,000. 

  
 35 

 (iv) The cash, shares of Common Stock or combination of cash and shares of
Common Stock due upon any conversion of Notes (the “Settlement Amount”) shall be computed as follows: 
 (A) if the Company elects (or is deemed to have elected) to satisfy its Conversion Obligation in respect of such conversion by Physical Settlement, the Company shall deliver to the converting Holder in
respect of each $1,000 principal amount of Notes being converted a number of shares of Common Stock equal to the sum of the Daily Conversion Rate Fractions for each of the 20 consecutive Trading Days during the related Conversion Period; 

(B) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Cash Settlement, the
Company shall pay to the converting Holder in respect of each $1,000 principal amount of Notes being converted cash in an amount equal to the sum of the Daily Conversion Values for each of the 20 consecutive Trading Days during the related
Conversion Period; and 
 (C) if the Company elects to satisfy its Conversion Obligation in respect of such
conversion by Combination Settlement, the Company shall pay or deliver, as the case may be, to the converting Holder in respect of each $1,000 principal amount of Notes being converted a Settlement Amount equal to the sum of the Daily Settlement
Amounts for each of the 20 consecutive Trading Days during the related Conversion Period. 
 (v) The sum of the
Daily Conversion Rate Fractions (if applicable), the Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable) shall be determined by the Company promptly following the last Trading Day of the Conversion Period.
Promptly after such determination of the sum of the Daily Conversion Rate Fractions, the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and (if applicable) the amount of cash payable in lieu of any fractional share, the
Company shall notify the Trustee and the Conversion Agent (if other than the Trustee) of the sum of the Daily Conversion Rate Fractions, the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and (if applicable) the amount
of cash payable in lieu of fractional shares of Common Stock. The Trustee and the Conversion Agent (if other than the Trustee) shall have no responsibility for any such determination. 

(b) Subject to Section 10.02(e), before any Holder of a Note shall be entitled to convert a Note as set forth above, such Holder
shall (i) in the case of a Note evidenced by a Global Security, comply with the procedures of the Depositary in effect at that time and, if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is
not entitled as set forth in Section 10.02(h) and (ii) in the case of a Note evidenced by an Individual Security (1) complete, manually sign and deliver an irrevocable notice to the Conversion Agent as set forth in the Form of Notice
of Conversion (or a facsimile thereof) (a “Notice of Conversion”) at the office of the Conversion Agent and state in writing therein the principal amount of Notes to be converted and the name or names (with addresses) in which such
Holder 

  
 36 

 
wishes the certificate or certificates for any shares of Common Stock to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrender such Notes, duly endorsed
to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent, (3) if required, furnish appropriate endorsements and transfer documents and (4) if required, pay funds
equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 10.02(h). The Trustee (and if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this
Article 10 on the Conversion Date for such conversion. No Notice of Conversion with respect to any Notes may be surrendered by a Holder thereof if such Holder has also delivered a Repurchase Notice or Fundamental Change Repurchase Exercise Notice to
the Company in respect of such Notes and not validly withdrawn such Repurchase Notice or Fundamental Change Repurchase Exercise Notice in accordance with Section 11.03. 
 If more than one Note shall be surrendered for conversion at one time by the same Holder, the Conversion Obligation with respect to such Notes shall be computed on the basis of the aggregate principal
amount of the Notes (or specified portions thereof to the extent permitted thereby) so surrendered. 
 (c) A Note shall be
deemed to have been converted immediately prior to the close of business on the date (the “Conversion Date”) that the Holder has complied with the requirements set forth in subsection (b) above. Subject to Section 10.03(b)
and the last sentence of this Section 10.02(c), the Company shall pay or deliver, as the case may be, the consideration due in respect of the Conversion Obligation on the third Business Day immediately following the last Trading Day of the
relevant Conversion Period. If any shares of Common Stock are due to converting Holders, the Company shall issue or cause to be issued, and deliver to the Conversion Agent or to such Holder, or such Holder’s nominee or nominees, certificates or
a book-entry transfer through the Depositary for the full number of shares of Common Stock to which such Holder shall be entitled in satisfaction of the Company’s Conversion Obligation. Notwithstanding the foregoing, if, prior to the Conversion
Date for any Notes surrendered for conversion, the Common Stock has been replaced by Reference Property that consists solely of cash pursuant to the provisions described under Section 10.07(a), the Company shall deliver the consideration due
upon conversion on the third Trading Day immediately following the relevant Conversion Date (in which case the consideration due upon conversion shall be determined based on a Daily Conversion Rate Fraction calculated assuming that the Daily VWAP
for each Trading Day in the applicable Conversion Period were equal to the per share amount of cash received by holders of the Common Stock in the relevant reclassification, recapitalization, change, consolidation, merger, binding share exchange,
sale, assignment, conveyance, transfer, lease or other disposition). 
 (d) In case any Note shall be surrendered for partial
conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Note so surrendered a new Note or Notes in authorized denominations in an aggregate principal amount equal to the
unconverted portion of the surrendered Note, without payment of any service charge by the converting Holder but, if required by the Company or Trustee, with payment of a sum sufficient to cover any transfer tax or similar governmental charge
required by law or that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such conversion being different from the name of the Holder of the old Notes surrendered for such conversion.

  
 37 

 (e) If a Holder submits a Note for conversion, the Company shall pay any documentary, stamp
or similar issue or transfer tax due on the issue of any shares of Common Stock upon conversion, unless the tax is due because the Holder requests such shares to be issued in a name other than the Holder’s name, in which case the Holder shall
pay that tax. The Conversion Agent may refuse to deliver the certificates representing the shares of Common Stock being issued in a name other than the Holder’s name until the Trustee receives a sum sufficient to pay any tax that is due by such
Holder in accordance with the immediately preceding sentence. 
 (f) Except as provided in Section 10.04, no adjustment
shall be made for dividends on any shares of Common Stock issued upon the conversion of any Note as provided in this Article 10. 
 (g) Upon the conversion of an interest in a Note evidenced by a Global Security, the Trustee, or the Security Custodian at the direction of the Trustee, shall make a notation on such Note as to the
reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversion of Notes effected through any Conversion Agent other than the Trustee. 

(h) Upon conversion of a Note, a Holder shall not receive any separate cash payment for accrued and unpaid interest, if any, except as
set forth below. The Company shall not adjust the Base Conversion Rate to account for accrued and unpaid interest, except that the Company shall pay on the Maturity Date accrued and unpaid interest to Holders at the close of business on the Regular
Record Date immediately preceding the Maturity Date regardless of whether such Holders convert their Notes. The Company’s settlement of the Conversion Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of
the Note and accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date shall be deemed to be paid in full rather
than cancelled, extinguished or forfeited. Upon a conversion of Notes into a combination of cash and shares of Common Stock, accrued and unpaid interest will be deemed to be paid first out of the cash paid upon such conversion. Notwithstanding the
foregoing, Holders of Notes as of the close of business on any Regular Record Date will receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion of such Notes at any time
after the close of business on such Regular Record Date. Notes surrendered for conversion by a Holder after the close of business on any Regular Record Date but prior to the open of business on the next Interest Payment Date must be accompanied by
payment of an amount equal to the interest that will be payable on the Notes so converted; provided, however, that no such payment need be made (1) if the Company has specified a Fundamental Change Repurchase Date 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 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 October 15, 2019; (4) with respect to any Notes surrendered for conversion following the Regular Record Date immediately preceding the
Maturity Date; or (5) to the extent of any Defaulted Interest, if any Defaulted Interest exists at the time of conversion with respect to such Note. 

  
 38 

 (i) The Person in whose name the certificate for any shares of Common Stock delivered upon
conversion is registered shall be treated as a stockholder of record as of the close of business on the last Trading Day of the related Conversion Period. Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered
for conversion. 
 (j) The Company shall not issue any fractional share of Common Stock upon conversion of the Notes and shall
instead pay cash in lieu of any fractional share of Common Stock issuable upon conversion based on the Daily VWAP for the Last Trading Day of the relevant Conversion Period. For each Note surrendered for conversion, the full number of shares that
shall be issued upon conversion thereof shall be computed on the basis of the aggregate Daily Conversion Rate Fractions, the aggregate Daily Settlement Amounts or the aggregate Daily Conversion Values, as the case may be, for each of the 20 Trading
Days during the relevant Conversion Period and any fractional shares remaining after such computation shall be paid in cash. 

Section 10.03. Adjustment to Daily Conversion Rate Fraction upon Conversion upon a Make-Whole Adjustment Event. (a) If a
Holder elects to convert its Notes at any time from, and including, the Effective Date of a Make-Whole Adjustment Event to, and including, the Scheduled Trading Day immediately preceding the related Fundamental Change Repurchase Date (or if a
Make-Whole Adjustment Event does not also constitute a Fundamental Change, the 35th Scheduled Trading Day immediately following the Effective Date of such Make-Whole Adjustment Event (such period, the “Make-Whole Adjustment Event
Period”)), the Daily Conversion Rate Fraction for each Trading Day in the relevant Conversion Period will be increased by an additional number of shares of Common Stock (such shares, the “Additional Shares”) as described
below. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of the anticipated Effective Date of such Make Whole Adjustment Event as soon as practicable after the Company publicly discloses such
anticipated Make Whole Adjustment Event (and shall make such notice available on its website). The Company shall also notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) as soon as practicable following the actual
Effective Date of any Make-Whole Adjustment Event (and make such notice available on its website). 
 (b) Upon surrender of
Notes for conversion during any Make-Whole Adjustment Event Period, the Company shall, at its option, satisfy the related Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with Section 10.02;
provided, however, that if, at the Effective Time of a Make-Whole Adjustment Event described in clause (b) of the definition of Change in Control, the Reference Property following such Make-Whole Adjustment Event is composed
entirely of cash, for any conversion of Notes following the Effective Date of such Make-Whole Adjustment Event, the Conversion Obligation shall be calculated based solely on the Stock Price for the transaction and shall be deemed to be an amount of
cash per $1,000 principal amount of converted Notes equal to the Applicable Conversion Rate (including any adjustment to the Daily Conversion Rate Fraction for Additional Shares, and calculated assuming that the Daily VWAP for each Trading Day in
the applicable Conversion Period were equal to such Stock Price), multiplied by such Stock Price. In such event, the Conversion Obligation shall be paid to Holders in cash on the third Trading Day following the relevant Conversion Date.

  
 39 

 (c) The number of Additional Shares by which the Daily Conversion Rate Fraction for each
Trading Day in the relevant Conversion Period shall be increased for conversions during any Make-Whole Adjustment Event Period shall be determined by reference to the table below, based on the date on which the Make-Whole Adjustment Event occurs or
becomes effective (the “Effective Date”) and the price (the “Stock Price”) paid (or deemed to be paid) per share of the Common Stock in the Make-Whole Adjustment Event. If the holders of the Common Stock receive
only cash in a Make-Whole Adjustment Event described in clause (b) of the definition of Change in Control, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Closing Sale Prices of
the Common Stock over the five consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Adjustment Event. The Board of Directors shall make appropriate adjustments to the
Stock Price, in its good faith determination, to account for any adjustment to the Base Conversion Rate that becomes effective, or any event requiring an adjustment to the Base Conversion Rate where the Ex-Dividend Date of the event occurs, during
such five consecutive Trading Day period. 
 (d) The Stock Prices set forth in the column headings of the table below shall be
adjusted as of any date on which the Base Conversion Rate of the Notes is otherwise adjusted. The adjusted Stock Prices shall equal the Stock Prices immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the
Base Conversion Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Base Conversion Rate as so adjusted. The number of Additional Shares shall be adjusted in the same manner and at
the same time as the Base Conversion Rate as set forth in Section 10.04. 
 (e) The following table sets forth the number
of Additional Shares by which the Daily Conversion Rate Fraction for each Trading Day in the relevant Conversion Period will be increased pursuant to this Section 10.03 for each Stock Price and Effective Date set forth below:

 The exact Stock Prices and Effective Dates may not be set forth in the table above, in which case:

 (i) if the Stock Price is between two Stock Prices in the table or the Effective Date is between two Effective
Dates in the table, the number of Additional Shares shall 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, as
applicable, based on a 365-day year; 

  
 40 

 (ii) if the Stock Price is greater than $75.00 per share (subject to
adjustment in the same manner as the Stock Prices in the column headings in the table above pursuant to subsection (d) above), no increase in the Daily Conversion Rate Fraction shall be made; and 

(iii) if the Stock Price is less than $11.02 per share (subject to adjustment in the same manner as the Stock Prices in
the column headings in the table above pursuant to subsection (d) above), no increase in the Daily Conversion Rate Fraction shall be made. 

Notwithstanding the foregoing, in no event shall the Daily Conversion Rate Fraction for any Trading Day in the relevant Conversion Period exceed
4.5372 per $1,000 principal amount of Notes, subject to adjustment in the same manner, on a proportional basis, as the Base Conversion Rate pursuant to Section 10.04. 

Section 10.04. Adjustment of Base Conversion Rate. The Base Conversion Rate shall be adjusted from time to time by the
Company if any of the following events occurs, except that the Company shall not make any adjustment to the Base Conversion Rate if Holders of the Notes participate (other than in the case of a share split or share combination), at the same time and
upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions described in this Section 10.04, without having to convert their Notes, as if they held a number of shares of Common
Stock, for each $1,000 principal amount of their Notes, equal to the Applicable Conversion Rate (calculated as if the Daily VWAP of the Common Stock for each Trading Day in the Conversion Period used to calculate the Applicable Conversion Rate were
the Daily VWAP of the Common Stock for the Trading Day immediately preceding the Effective Date or Ex-Dividend Date, as the case may be, of such transaction or event). Concurrently with any adjustment, readjustment, increase or decrease of the Base
Conversion Rate pursuant to clauses (a) through (e) of this Section 10.04, the Daily Conversion Rate Cap and the Incremental Share Factor shall be proportionately adjusted, readjusted, increased or decreased, as the case may be, on
the same basis as the Base Conversion Rate. 
 (a) If the Company issues solely shares of Common Stock as a dividend or
distribution on all or substantially all shares of the Common Stock, or if the Company subdivides or combines the Common Stock, the Base Conversion Rate shall be adjusted based on the following formula: 

 
 

 
 where, 
  

					
	CR0	  	=	  	the Base 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;
			
	CR'	  	=	  	the Base Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately after the open of business on the
Effective Date of such subdivision or combination of Common Stock, as the case may be;

  
 41 

					
	OS0	  	=	  	the number of shares of the Common Stock outstanding 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; and
			
	OS'	  	=	  	the number of shares of Common Stock outstanding immediately after such dividend or distribution, or immediately after the Effective Date of such subdivision or combination of
Common Stock, as the case may be, after giving effect to such issuance, subdivision or combination.

 Any adjustment made under this Section 10.04(a) shall become effective immediately after the open of business on the
Ex-Dividend Date for such dividend or distribution, or immediately after the open of business on the Effective Date of such share subdivision or combination of Common Stock, as the case may be. If any dividend or distribution of the type described
in this Section 10.04(a) is declared but not so paid or made, the Base Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay or make such dividend or distribution, to the Base
Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
 (b) If the Company
issues to all or substantially all holders of the Common Stock any rights, options or warrants entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of the
Common Stock at a price per share that is less than the Closing Sale Price of the Common Stock on the Trading Day immediately preceding the announcement date of such issuance, the Base Conversion Rate shall be increased based on the following
formula: 
  
 

 
 where, 
  

					
	CR0	  	=	  	the Base Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such issuance;
			
	CR'	  	=	  	the Base Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such issuance;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the open of business on the Ex-Dividend Date for such issuance;
			
	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 Closing Sale Price of the Common Stock
on the Trading Day immediately preceding the announcement date of such issuance.

  
 42 

 Any increase made under this Section 10.04(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 issuance. To the extent that shares of the Common Stock are not delivered after the expiration of such rights, options
or warrants, the Base Conversion Rate shall be decreased to the Base 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 issued, the Base Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not to make such issuance, to the Base
Conversion Rate that would then be in effect if the Ex-Dividend Date for such issuance had not occurred. 
 For purposes of this
Section 10.04(b) and for purposes of Section 10.01(b)(ii)(A), in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of the Common Stock at a price per share that is less than the
Closing Sale Price of the Common Stock on the Trading Day immediately preceding the announcement date of such issuance, there shall be taken into account any consideration received by the Company 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 by the Board of Directors. 
 (c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company, rights, options or warrants to acquire its Capital Stock or other
securities, to all or substantially all holders of the Common Stock (excluding (i) dividends, distributions or issuances as to which an adjustment was effected pursuant to Section 10.04(a) or Section 10.04(b), (ii) dividends or
distributions paid exclusively in cash as to which an adjustment was effected pursuant to Section 10.04(d), and (iii) Spin-Offs as to which an adjustment was effected pursuant to this Section 10.04(c)) (any of such shares of Capital
Stock, evidences of indebtedness, other assets or property, rights, options or warrants to acquire Capital Stock or other securities, the “Distributed Property”), then the Base Conversion Rate shall be increased based on the
following formula: 
  
 

 
 where, 
  

					
	CR0	  	=	  	the Base Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;
			
	CR'	  	=	  	the Base Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such
distribution;

  
 43 

					
	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 by the Board of Directors) of the Distributed Property with respect to each outstanding share of the Common Stock as of the open of business on
the Ex-Dividend Date for such distribution.

 Any increase made under the portion of this Section 10.04(c) above shall become effective
immediately after the open of business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Base Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not to make
such distribution, to the Base 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, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock receive the Distributed Property, the amount and kind of Distributed Property such Holder would have
received if such Holder owned a number of shares of Common Stock equal to the Applicable Conversion Rate (calculated as if the Daily VWAP for each Trading Day in the Conversion Period used to calculate the Applicable Conversion Rate were the Daily
VWAP for the Trading Day immediately preceding the Ex-Dividend Date for such distribution). If the Board of Directors determines the “FMV” (as defined above) of any distribution for purposes of this Section 10.04(c) by reference to
the actual or when-issued trading market for any securities, it shall in doing so consider the prices in such market over the same period used in computing 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. 
 With
respect to an adjustment pursuant to this Section 10.04(c) where there has been a payment of 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 of the Company, that are, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange (a “Spin-Off”), the Base Conversion Rate shall be increased based on the
following formula: 
  
 

 
 where, 
  

					
	CR0	  	=	  	the Base Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for the Spin-Off;
			
	CR'	  	=	  	the Base Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for the
Spin-Off;

  
 44 

					
	FMV	  	=	  	the average of the Closing Sale Prices of the Capital Stock or similar equity interests distributed to holders of the Common Stock applicable to one share of the Common Stock
(determined by reference to the definition of Closing Sale Price as set forth in Section 1.02 as if references therein to Common Stock were to such Capital Stock or similar equity interest) over the first 10 consecutive Trading Day period
immediately following, and including, the Ex-Dividend Date for the Spin-Off (such period, the “Spin-Off Valuation Period”); and
			
	MP0	  	=	  	the average of the Closing Sale Prices of the Common Stock over the Spin-Off Valuation Period.

 The adjustment to the Base Conversion Rate under the preceding paragraph shall be made immediately after the close of
business on the last Trading Day of the Spin-Off Valuation Period, but will be given effect as of the open of business on the Ex-Dividend Date for the Spin-Off. If the Ex-Dividend Date for the Spin-Off is less than 10 Trading Days prior to, and
including, the end of the Conversion Period in respect of any conversion of Notes, references within this portion of Section 10.04(c) related to “Spin-Offs” to 10 Trading Days shall be deemed to be replaced, for purposes of
calculating the consideration due in respect of such conversion of Notes, with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for the Spin-Off to, and including, the last Trading Day of such Conversion
Period. For purposes of determining the Base Conversion Rate, in respect of any conversion during the 10 Trading Days commencing on the Ex-Dividend Date for any Spin-Off, references within the portion of this Section 10.04(c) related to
“Spin-Offs” to 10 Trading Days shall be deemed to be replaced with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for such Spin-Off to, but excluding, the relevant Conversion Date. 

For purposes of this Section 10.04(c) (and subject in all respect to Section 10.11), rights, options or warrants distributed by
the Company to all holders of its Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until
the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of the Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future
issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this Section 10.04(c) (and no adjustment to the Base Conversion Rate under this Section 10.04(c) will be required) until the occurrence of the
earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Base Conversion Rate shall be made under this Section 10.04(c). If any such
right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this First Supplemental Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become
exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date with respect to new rights,
options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders thereof). In addition, in the event of any distribution (or
deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the immediately preceding sentence) with respect thereto that was counted for purposes of

  
 45 

 
calculating a distribution amount for which an adjustment to the Base Conversion Rate under this Section 10.04(c) was made, (1) in the case of any such rights, options or warrants that
shall all have been redeemed or purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the Base Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and
(y) the Base Conversion Rate shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase
price received by a holder or holders of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or
purchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Base Conversion Rate shall be readjusted as if such rights, options and warrants had not
been issued. 
 For purposes of Section 10.04(a), Section 10.04(b) and this Section 10.04(c), any dividend or
distribution to which this Section 10.04(c) is applicable that also includes one or both of: 
 (A) a dividend or
distribution of shares of Common Stock to which Section 10.04(a) is applicable (the “Clause A Distribution”); or 
 (B) a dividend or distribution of rights, options or warrants to which Section 10.04(b) is applicable (the “Clause B Distribution”), 

then (1) such dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or
distribution to which this Section 10.04(c) is applicable (the “Clause C Distribution”) and any Base Conversion Rate adjustment required by this Section 10.04(c) with respect to such Clause C Distribution shall then be
made, and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Base Conversion Rate adjustment required by Section 10.04(a) and Section 10.04(b) with respect
thereto shall then be made, except that, if determined by the Company (I) the “Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and
(II) any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date” within the meaning
of Section 10.04(a) or “outstanding immediately prior to the open of business on such Ex-Dividend Date” within the meaning of Section 10.04(b). 
 (d) If the Company makes or pays any cash dividend or distribution to all or substantially all holders of the Common Stock (other than distributions described in Section 10.04(e)), the Base
Conversion Rate shall be increased based on the following formula: 
  
 

 

  
 46 

 where, 
  

					
	CR0	  	=	  	the Base Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	CR'	  	=	  	the Base Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	SP0	  	=	  	the average of the Closing Sale Prices of the Common Stock over the five consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the
Ex-Dividend Date for such dividend or distribution; and
			
	C	  	=	  	the amount in cash per share the Company pays or distributes to all or substantially all holders of the Common Stock.

 Any increase pursuant to this Section 10.04(d) shall become effective immediately after the open
of business on the Ex-Dividend Date for such dividend or distribution. If any dividend or distribution described in this Section 10.04(d) is declared but not so paid or made, the Base Conversion Rate shall be decreased, effective as of the date
the Board of Directors determines not to pay or make such dividend or distribution, to the Base 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 to the Base Conversion Rate, each Holder of a Note shall receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of shares of the 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 Applicable Conversion Rate (calculated as if the Daily VWAP for each Trading Day in the Conversion Period used to calculate the
Applicable Conversion Rate were the Daily VWAP for the Trading Day immediately preceding the Ex-Dividend Date for such 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 the cash and value of any other consideration included in the payment per
share of the 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 Base Conversion Rate shall be increased based on the following formula: 
  

 
 where, 
  

					
	CR0	  	=	  	the Base Conversion Rate in effect immediately prior to the open of business on the Trading Day next succeeding the Expiration Date;
			
	CR'	  	=	  	the Base Conversion Rate in effect immediately after the open of business on the Trading Day next succeeding the Expiration
Date;

  
 47 

					
	AC	  	=	  	the aggregate value of all cash and any other consideration (as determined 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 or exchange of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer);
			
	OS'	  	=	  	the number of shares of Common Stock outstanding immediately after the Expiration Time (after giving effect to the purchase or exchange of all shares of Common Stock accepted for
purchase or exchange in such tender or exchange offer); and
			
	SP'	  	=	  	the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period (the “Tender Valuation Period”) commencing on, and including,
the Trading Day next succeeding the Expiration Date.

 The adjustment to the Base Conversion Rate under this Section 10.04(e) shall be made immediately after the close of
business on the last day of the Tender Valuation Period, but will be given effect at the open of business on the Trading Day next succeeding the Expiration Date. If the Trading Day next succeeding the Expiration Date is less than 10 Trading Days
prior to, and including, the end of the Conversion Period in respect of any conversion, references within this Section 10.04(e) to 10 Trading Days shall be deemed to be replaced, for purposes of calculating the consideration due in respect of
such conversion, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Expiration Date to, and including, the last Trading Day of such Conversion Period. For purposes of determining the Base
Conversion Rate, in respect of any conversion during the 10 Trading Days commencing on the Trading Day next succeeding the Expiration Date, references within this Section 10.04(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. 
 (f) If: 
 (i) shares of Common Stock are deliverable in respect of
a given Trading Day in the relevant Conversion Period; 
 (ii) any distribution or transaction described in
clauses (a), (b), (c), (d) and (e) of this Section 10.04 has not yet resulted in an adjustment to the Base Conversion Rate on such Trading Day; and 

(iii) the shares of Common Stock a Holder of Notes will receive in respect of such Trading Day are not entitled to
participate in the relevant distribution or transaction (because they were not held on a related Record Date or otherwise), 

  
 48 

 then the Company shall adjust the number of shares of Common Stock that it delivers to such Holder in
respect of the relevant Trading Day to reflect the relevant distribution or transaction. 
 (g) Notwithstanding this
Section 10.04 or any other provision of the Indenture or the Notes, if an adjustment to the Base Conversion Rate becomes effective on any Ex-Dividend Date, and a Holder that has converted its Notes would be treated as the record holder of the
shares of Common Stock based on an adjusted Base Conversion Rate for such Ex-Dividend Date, then, notwithstanding the Base Conversion Rate adjustment provisions in this Section 10.04, the adjustment to the Base Conversion Rate relating to such
Ex-Dividend Date shall not be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of the shares of Common Stock on an unadjusted basis and participate in the related dividend, distribution
or other event giving rise to such adjustment. 
 (h) Except as stated herein, the Company shall not adjust the Base Conversion
Rate for the issuance of shares of its Common Stock or any securities convertible into or exchangeable for shares of its Common Stock or the right to purchase shares of its Common Stock or such convertible or exchangeable securities. 

(i) In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 10.04, and to the
extent permitted by applicable law and subject to the applicable rules of any exchange on which any of the Company’s securities are then listed (1) the Company is permitted to increase the Base Conversion Rate, the Incremental Share Factor
and/or the Daily Conversion Rate Cap 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 (2) the Company may (but is not required to) increase the Base Conversion Rate, the Incremental Share Factor and/or the Daily Conversion Rate Cap to avoid or diminish any 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. Whenever the Base Conversion Rate, the Incremental Share Factor or the Daily Conversion Rate Cap is
increased pursuant to either of the preceding two sentences, the Company shall mail to the Holder of each Note at its last address appearing on the Register a notice of the increase prior to the date the increased Base Conversion Rate, Incremental
Share Factor and/or Daily Conversion Rate Cap takes effect, and such notice shall state the increased Base Conversion Rate, Conversion Rate Cap and/or Incremental Share Factor and the period during which it will be in effect. 

(j) Notwithstanding anything to the contrary in this Article 10, the Base Conversion Rate shall not be adjusted: 

(i) upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment
of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan; 
 (ii) upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or future employee, director or consultant benefit plan or program of or assumed
by the Company or any of the Company’s Subsidiaries; 

  
 49 

 (iii) upon the issuance of any shares of the Common Stock pursuant to any
option, warrant, right or exercisable, exchangeable or convertible security not described in clause (ii) of this subsection and outstanding as of the date the Notes were first issued; 

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

(v) for accrued and unpaid interest, if any. 
 (k) All calculations and other determinations under this Article 10 shall be made by the Company and shall be made to the nearest one-ten thousandth (1/10,000) of a share, and adjustments to the Base
Conversion Price shall be made to the nearest one-hundredth (1/100th) of a cent. Notwithstanding anything in this Section 10.04 to the contrary, the Company shall not be required to adjust the Base Conversion Rate unless the adjustment
would result in a change of at least 1% of the Base Conversion Rate. However, the Company shall carry forward any adjustments that are less than 1% of the Base Conversion Rate and make such carried forward adjustments, regardless of whether the
aggregate adjustment is greater than 1%, (i) upon any conversion of Notes (and on each Trading Day in the related Conversion Period) and (ii) upon any required repurchase of the Notes pursuant to Article 11. 

(l) Whenever the Base Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee (and the
Conversion Agent if not the Trustee) an Officer’s Certificate setting forth the Base Conversion Rate (and the proportionally adjusted Daily Conversion Rate Cap and Incremental Share Factor, if applicable) after such adjustment and setting forth
a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officer’s Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Base
Conversion Rate, Daily Conversion Rate Cap (if applicable) or Incremental Share Factor (if applicable) and may assume without inquiry that the last Base Conversion Rate, the Daily Conversion Rate Cap (if applicable) and the Incremental Share Factor
(if applicable), as the case may be, of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall make the relevant information contained in such Officer’s Certificate available on its website.
Failure to do so shall not affect the legality or validity of any such adjustment. 
 (m) For purposes of this
Section 10.04, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in
the treasury of the Company, but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. 
 Section 10.05. Adjustments of Prices. Whenever any provision of the Indenture requires the Company to calculate the Closing Sale Prices, the Daily VWAPs, the Daily Conversion Values, the Daily
Conversion Rate Fractions or the Daily Settlement Amounts over a span of multiple days (including the Stock Price for purposes of a Make-Whole Adjustment Event or the calculation of average Closing Sale Prices for purposes of determining adjustments
to the Base 

  
 50 

 
Conversion Rate), the Board of Directors shall make appropriate adjustments to each to account for any adjustment to the Base Conversion Rate that becomes effective, or any event requiring an
adjustment to the Base Conversion Rate where the Ex-Dividend Date or Effective Date of the event occurs, at any time during the period when the Closing Sale Prices, the Daily VWAPs, the Daily Conversion Values, the Daily Conversion Rate Fractions or
the Daily Settlement Amounts are to be calculated. 
 Section 10.06. Shares to Be Fully Paid. The Company shall
provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for conversion of the Notes from time to time as such Notes are presented for conversion
(assuming that at the time of computation of such number of shares, all such Notes would be converted by a single Holder and that Physical Settlement is applicable). 
 Section 10.07. Effect of Recapitalizations, Reclassifications and Changes of the Common Stock. 
 (a) In the event of: 
 (i) any reclassification, recapitalization
or change of the Common Stock (other than changes resulting from a subdivision or combination), 
 (ii) any
consolidation, merger or binding share exchange involving the Company or 
 (iii) any sale, assignment,
conveyance, transfer, lease or other disposition to another Person of the property and assets of the Company as an entirety or substantially as an entirety or 
 in each case, in which holders of the outstanding Common Stock are entitled to receive cash, securities or other property for their shares of Common Stock (any such event, a “Merger
Event”), then, at and after the effective time of the such Merger Event, Holders will be entitled thereafter to convert their Notes into the kind and amount of cash, securities or other property that a holder of one share of Common Stock
would have owned or been entitled to receive (the “Reference Property”) upon such Merger Event and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may be, shall
execute with the Trustee a supplemental indenture permitted under Section 8.02(h) providing for such change in the right to convert each $1,000 principal amount of Notes; provided, however, that at and after the effective time of
the Merger Event (A) the Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of Notes in accordance with Section 10.02 and (B) (I) any
amount payable in cash upon conversion of the Notes in accordance with Section 10.02 shall continue to be payable in cash, (II) any shares of Common Stock that the Company would have been required to deliver upon conversion of the Notes in
accordance with Section 10.02 shall instead be deliverable in the amount and type of Reference Property that a holder of that number of shares of Common Stock would have received in such Merger Event and (III) the Daily VWAP shall be calculated
based on the value of a unit of the Reference Property that a holder of one share of Common Stock would have received in such Merger Event. If the Notes become convertible into cash, 

  
 51 

 
Reference Property or a combination thereof, the Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) (and make such notice available on the
Company’s website). Throughout this Article 10, if Common Stock has been replaced by Reference Property as a result of any transaction described in this Section 10.07, references to Common Stock will be deemed to be references to a unit of
Reference Property that a holder of one share of Common Stock would have been entitled to receive in such transaction. 
 If the
Merger Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), the Reference Property into which the Notes
will be convertible (subject to the Company’s right to elect Cash Settlement or Combination Settlement) shall 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, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as soon as practicable after such determination is made. 

Such supplemental indenture described in the second immediately preceding paragraph shall provide for anti-dilution and other adjustments
that shall be as nearly equivalent as is possible to the adjustments provided for in this Article 10. If, in the case of any Merger Event, the Reference Property includes shares of stock, securities or other property or assets (including cash or any
combination thereof) of a Person other than the successor or purchasing corporation, as the case may be, in such Merger Event, then such supplemental indenture shall also be executed by such other Person and shall contain such additional provisions
to protect the interests of the Holders of the Notes as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including the provisions providing for the purchase rights set forth in Article 11. 

(b) When the Company executes a supplemental indenture pursuant to subsection (a) of this Section 10.07, the Company shall
promptly file with the Trustee an Officer’s Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or asset that will comprise the Reference Property after any such Merger Event, any adjustment to
be made with respect thereto and that all conditions precedent have been complied with. The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, at its address appearing on the Register provided for
in the Indenture, within 20 days after execution thereof. At the Company’s request, the Trustee shall give such notice in the Company’s name and at the Company’s expense; provided, however, that, in all cases, the text
of such notice shall be prepared by the Company. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. 
 (c) The Company shall not become a party to any Merger Event unless its terms are consistent with this Section 10.07. None of the foregoing provisions shall affect the right of a holder of Notes to
convert its Notes into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, as set forth in Section 10.01 and Section 10.02 prior to the effective date of such Merger Event. 

(d) The above provisions of this Section shall similarly apply to successive Merger Events. 

  
 52 

 Section 10.08. Certain Covenants. (a) The Company covenants that all shares
of Common Stock issued upon conversion of Notes will be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof. 

(b) The Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder require
registration with or approval of any governmental authority under any federal or state law before such shares may be validly issued upon conversion, the Company will secure such registration or approval, as the case may be. 

(c) The Company further covenants that if at any time the Common Stock shall be listed on any national securities exchange or automated
quotation system the Company will list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation system, any Common Stock issuable upon conversion of the Notes. 

Section 10.09. Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty
or responsibility to any Holder to determine the Base Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the Base Conversion Rate, or with respect to the nature or
extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be
accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities, property or cash that may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any
other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or
other securities or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 10. Without limiting the generality of the
foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 10.07 relating either to the kind
or amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Notes after any event referred to in such Section 10.07 or to any adjustment to be made with respect thereto, but,
subject to the provisions of Section 11.02 and Section 11.08 of the Base Indenture, may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in relying
upon, the Officer’s Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. Neither the Trustee nor the Conversion Agent shall be responsible
for determining whether any event contemplated by Section 10.01(b) has occurred that makes the Notes eligible for conversion or no longer eligible therefor until the Company has delivered to the Trustee and the Conversion Agent the notices
referred to in Section 10.01(b) with respect to the commencement or termination of such conversion rights, on which notices the Trustee and the Conversion Agent may conclusively rely, and the Company agrees to deliver such notices to the
Trustee and the Conversion Agent immediately after the occurrence of any such event or at such other times as shall be provided for in Section 10.01(b). 

  
 53 

 Section 10.10. Notice to Holders Prior to Certain Actions. In case of any:

 (a) action by the Company or one of its Subsidiaries that would require an adjustment in the Base Conversion Rate, the
Incremental Share Factor, the Daily Conversion Rate Fraction or the Daily Conversion Rate Cap pursuant to Section 10.04, Section 10.07 or Section 10.11; 
 (b) Merger Event; or 
 (c) voluntary or involuntary dissolution, liquidation or
winding-up of the Company or any of its Subsidiaries; 
 then, in each case (unless notice of such event is otherwise required pursuant to
another provision of the Indenture), the Company shall cause to be filed with the Trustee and the Conversion Agent (if other than the Trustee) and to be mailed to each Holder at its address appearing on the Register, as promptly as possible but in
any event at least 20 days prior to the applicable date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such action by the Company or one of its Subsidiaries or, if a record is not to be
taken, the date as of which the holders of Common Stock of record are to be determined for the purposes of such action by the Company or one of its Subsidiaries, or (ii) the date on which such Merger Event, dissolution, liquidation or
winding-up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such Merger Event,
dissolution, liquidation or winding-up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such action by the Company or one of its Subsidiaries, Merger Event, dissolution, liquidation or winding-up.

 Section 10.11. Stockholder Rights Plans. To the extent that the Company has a rights plan in effect upon
conversion of the Notes, each share of Common Stock, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear
such legends, if any, in each case, as may be provided by the terms of any such rights plan, as the same may be amended from time to time. However, if, prior to any conversion, the rights have separated from the shares of Common Stock in accordance
with the provisions of the applicable rights plan, the Base Conversion Rate, the Incremental Share Factor and the Daily Conversion Rate Cap shall be adjusted at the time of separation as if the Company distributed to all or substantially all holders
of the Common Stock Distributed Property as provided in Section 10.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights. 
 ARTICLE 11 
 REPURCHASE OF NOTES
AT OPTION OF HOLDERS 
 Section 11.01. Repurchase at Option
of Holders.  
 (a) Each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for
cash on each of October 15, 2019, October 15, 2024, and October 15, 2029 (each, a “Repurchase Date”), all of such Holder’s Notes, or any portion thereof that is an

  
 54 

 
integral multiple of $1,000 principal amount, at a repurchase price (the “Repurchase Price”) that is equal to 100% of the principal amount of the Notes to be repurchased,
plus accrued and unpaid interest to, but excluding, such Repurchase Date; provided that any such accrued and unpaid interest shall be paid not to the Holder submitting the Notes for repurchase on the relevant Repurchase Date but
instead to the Holders of such Notes at the close of business on the Regular Record Date immediately preceding such Repurchase Date. On or before the 20th Business Day prior to each Repurchase Date, the Company shall provide a notice (the
“Company Notice”) to the Trustee, to the Paying Agent and to each Holder at its address shown in the Register of the Registrar in accordance with Section 13.07 (and to beneficial owners as required by applicable law). The
Company Notice shall include a form of Repurchase Notice to be completed by a holder and shall state: 
 (i) the
last date on which a Holder may exercise its repurchase right pursuant to this Section 11.01 (the “Repurchase Expiration Time”); 
 (ii) the Repurchase Price; 
 (iii) the name and address of the
Conversion Agent and Paying Agent; 
 (iv) that the Notes with respect to which a Repurchase Notice has been
delivered by a Holder may be converted (if such Notes are convertible in accordance with the terms of the Indenture) only if the Holder withdraws the Repurchase Notice in accordance with the terms of the Indenture; 

(v) that the Holder shall have the right to withdraw any Notes surrendered prior to the Repurchase Expiration Time; and

 (vi) the procedures a Holder must follow to exercise its repurchase rights under this Section 11.01 and a
brief description of those rights. 
 At the Company’s request, the Trustee shall give such notice in the Company’s name and at the
Company’s expense; provided, however, that, in all cases, the text of such Company Notice shall be prepared by the Company. 
 Simultaneously with providing the Company Notice, the Company shall publish a notice containing the information included in the Company Notice on the Company’s website or through such other public
medium as the Company may use at that time. 
 No failure of the Company to give the foregoing notices and no defect therein
shall limit the Holders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 11.01. 
 Repurchases of Notes under this Section 11.01 shall be made, at the option of the Holder thereof, upon: 
 (A) delivery to the Paying Agent by the Holder of a duly completed notice (the “Repurchase Notice”) in the form set forth in Attachment 3 to the Form of Note attached hereto as Exhibit A,
if the Notes are evidenced by 

  
 55 

 
Individual Securities, or in compliance with the Depositary’s procedures for surrendering interests in Notes evidenced by Global Securities, if the Notes are evidenced by Global Securities,
in each case, during the period beginning at any time from the open of business on the date on which the Company mails or delivers to the Trustee, the Paying Agent and each Holder the Company Notice (or, if earlier, the 20th Business Day immediately
preceding the relevant Repurchase Date) until the close of business on the Business Day immediately preceding the Repurchase Date; and 
 (B) delivery of the Notes, if the Notes are evidenced by Individual Securities, to the Paying Agent at any time after delivery of the Repurchase Notice (together with all necessary endorsements) at the
Corporate Trust Office of the Paying Agent, or book-entry transfer of the Notes, if the Notes are evidenced by Global Securities, in compliance with the procedures of the Depositary, in each case, such delivery being a condition to receipt by the
Holder of the Repurchase Price therefor. 
 Each Repurchase Notice shall state: 

(A) in the case of Notes evidenced by Individual Securities, the certificate numbers of the Notes to be delivered for
repurchase; 
 (B) the portion of the principal amount of the Notes to be repurchased, which must be $1,000 or an
integral multiple thereof; and 
 (C) that the Notes are to be repurchased by the Company pursuant to the
applicable provisions of the Notes and the Indenture; 
 provided, however, that if the Notes are evidenced by Global Securities,
the Repurchase Notice must comply with appropriate Depositary procedures. 
 Notwithstanding anything herein to the contrary,
any Holder delivering to the Paying Agent the Repurchase Notice contemplated by this Section 11.01 shall have the right to withdraw, in whole or in part, such Repurchase Notice at any time prior to the close of business on the Business Day
immediately preceding the Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 11.03. 
 The Paying Agent shall promptly notify the Company of the receipt by it of any Repurchase Notice or written notice of withdrawal thereof. 

No Repurchase Notice with respect to any Notes may be surrendered by a Holder thereof if such Holder has also surrendered a Fundamental
Change Repurchase Exercise Notice and not validly withdrawn such Fundamental Change Repurchase Exercise Notice in accordance with Section 11.03. 
 (b) Notwithstanding the foregoing, no Notes may be repurchased by the Company at the option of the Holders on any Repurchase Date if the principal amount of the Notes has been

  
 56 

 
accelerated, and such acceleration has not been rescinded, on or prior to such 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 will promptly return to the respective Holders thereof any Notes evidenced by Individual Securities held by it during the acceleration of the Notes (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), or any instructions for book-entry transfer of the Notes in compliance with the procedures of the Depositary shall be deemed to have been
cancelled, and, upon such return or cancellation, as the case may be, the Repurchase Notice with respect thereto shall be deemed to have been withdrawn. 
 Section 11.02. Repurchase at Option of Holders Upon a Fundamental Change. (a) If a Fundamental Change occurs at any time, each Holder shall have the right, at such Holder’s option,
to require the Company to repurchase for cash all of such Holder’s Notes, or any portion thereof that is equal to $1,000 or an integral multiple of $1,000, on the date (the “Fundamental Change Repurchase Date”) specified by the
Company that is not less than 20 Business Days or more than 35 Business Days (subject to extension if required by law) after the date on which the Fundamental Change Repurchase Right Notice is mailed to the Trustee and to each Holder at a repurchase
price equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), unless the Fundamental
Change Repurchase Date falls after a Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay the full amount of accrued and unpaid interest to Holders of
record as of such Regular Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be repurchased pursuant to this Article 11 and shall not include any accrued and unpaid interest.

 (b) Repurchases of Notes under this Section 11.02 shall be made, at the option of the Holder thereof, upon: 

(i) delivery to the Paying Agent by a Holder of a duly completed notice (the “Fundamental Change Repurchase

Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change Repurchase Exercise
Notice contemplated by this Section 11.02 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Exercise Notice at any time prior to the close of business on the Business Day immediately preceding the
Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 11.03. 
 The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Exercise Notice or written notice of withdrawal thereof. 

(c) On or before the 10th Business Day after the occurrence of the effective date of a Fundamental Change, the Company shall provide to
all Holders of Notes and the Trustee and the Paying Agent (in the case of a Paying Agent other than the Trustee) a notice (the “Fundamental Change Repurchase Right Notice”) of the occurrence of the effective date of the Fundamental
Change and of the repurchase right at the option of the Holders arising as a result thereof. In the case of Notes evidenced by Individual Securities, such notice shall be by first class mail or, in the case of Notes evidenced by Global Securities,
such notice shall be delivered in accordance with the applicable procedures of the Depositary. Simultaneously with providing such notice, the Company shall publish a notice containing the information set forth in the Fundamental Change Repurchase
Right Notice on the Company’s website or through such other public medium as the Company may use at that time. Each Fundamental Change Repurchase Right Notice shall specify:

 (xi) that the Notes with respect to which a
Fundamental Change Repurchase Exercise Notice has been delivered by a Holder may be converted only if the Holder withdraws the Fundamental Change Repurchase Exercise Notice in accordance with the terms of the Indenture. 

No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect
the validity of the proceedings for the repurchase of the Notes pursuant to this Section 11.02. 
 At the Company’s
request, the Trustee shall give such notice in the Company’s name and at the Company’s expense; provided, however, that, in all cases, the text of such Fundamental Change Repurchase Right Notice shall be prepared by the
Company. 
 (d) Notwithstanding the foregoing, no Notes may be repurchased by the Company on any date at the option of the
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 such 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 will promptly return to the respective Holders thereof any Notes evidenced by Individual Securities held by it during the acceleration of the Notes
(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), or any instructions for book-entry transfer of the Notes in compliance with the
procedures of the Depositary shall be deemed to have been cancelled, and, upon such return or cancellation, as the case may be, the Fundamental Change Repurchase Exercise Notice with respect thereto shall be deemed to have been withdrawn.

Repurchase Notice or Fundamental Change Repurchase Exercise Notice may be withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to

 (i) the principal amount of the Notes with respect to which such notice of withdrawal is being submitted, 
 (ii) if Notes evidenced by Individual Securities have been issued, the certificate number of the Note in respect of which such notice of withdrawal is being submitted, and 

(iii) the principal amount, if any, of such Note that remains subject to the original Repurchase Notice or Fundamental
Change Repurchase Exercise Notice, as the case may be, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000; 

provided, however, that if the Notes are evidenced by Global Securities, the notice must comply with appropriate procedures of the
Depositary.

immediately preceding the Repurchase Date or the Fundamental Change Repurchase Date, as the case may be) will be made on the later of (i) the Repurchase Date or Fundamental Change Repurchase Date, as the case may be, (provided the Holder
has satisfied the conditions in Section 11.01 or Section 11.02, as the case may be) and (ii) the time of book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder
thereof in the manner required by Section 11.01 or Section 11.02, as applicable, by mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in the Register; provided, however,
that payments to the Depositary shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Trustee shall, promptly after such payment and upon written demand by the Company, return to the
Company any funds in excess of the Repurchase Price or Fundamental Change Repurchase Price, as the case may be. 
 (b) If by
11:00 a.m. New York City time, on the Repurchase Date or Fundamental Change Repurchase Date, as the case may be, the Trustee (or other Paying Agent appointed by the Company) holds money sufficient to make payment on all the Notes or portions thereof
that are to be repurchased on such Repurchase Date or Fundamental Change Repurchase Date, as the case may be, then, with respect to the Notes that have been properly surrendered for repurchase

  
 60 

 
and not validly withdrawn, (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 (x) the right to receive the Repurchase Price or Fundamental Change Repurchase Price, as
the case may be, upon book-entry transfer or delivery of the Notes, (y) the right of the Holders as of the Regular Record Date immediately preceding the relevant Repurchase Date to receive the relevant interest payment and (z) if the
Fundamental Change Repurchase Date falls after a Regular Record Date and on or before the Interest Payment Date to which such Regular Record Date relates, the right of the Holders as of such Regular Record Date to receive the relevant interest
payment). 
 (c) Upon surrender of a Note that is to be repurchased in part pursuant to Section 11.01 or
Section 11.02, the Company shall execute and the Trustee shall authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the unrepurchased portion of the Note surrendered. 

Section 11.05. Covenant to Comply with Applicable Laws Upon Repurchase of Notes. In connection with any repurchase offer, the
Company will, if required: 
 (a) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under
the Exchange Act, to the extent any such rules are applicable; 
 (b) file a Schedule TO or any successor or similar schedule;
and 
 (c) otherwise comply with all applicable federal and state securities laws in connection with any offer by the Company to
repurchase the Notes;

manner specified in this Article 11.

 Section 12.01.
Applicability of Articles IV and V of the Base Indenture. (a) Article IV of the Base Indenture shall not apply to the Notes. Instead, the redemption provisions set forth in this Article 12 shall, with respect to the Notes, supersede in
its entirety Article IV of the Base Indenture, and all references in the Base Indenture to Article IV thereof and redemption provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to this Article 12 and
the redemption provisions set forth in this Article 12. 
 (b) Article V of the Base Indenture shall not apply to the Notes.

 Section 12.02. Optional Redemption. No sinking fund is provided for the Notes. The Notes shall not be redeemable

Redemption”) for cash all or part of the Notes at the Redemption Price. 

  
 61 

 Section 12.03. Notice of Optional Redemption; Selection of Notes. (a) In
case the Company exercises its right to redeem all or, as the case may be, any part of the Notes pursuant to this Article 12, it shall fix a Redemption Date, and it or, at its written request received by the Trustee not less than 40 Business Days
prior to the Redemption Date (or such shorter period of time as may be acceptable to the Trustee), the Trustee, in the name of and at the expense of the Company, shall mail or cause to be mailed a notice of such Optional Redemption (a
“Redemption Notice”) not less than 30 nor more than 60 Business Days prior to the Redemption Date to each Holder of Notes so to be redeemed as a whole or in part at its last address as the same appears on the Register;
provided, however, that, if the Company shall give such notice, it shall also give written notice of the Redemption Date to the Trustee. The Redemption Date must be a Business Day. 

(b) The Redemption Notice, if mailed (or otherwise delivered) in the manner herein provided, shall be conclusively presumed to have been
duly given, whether or not the Holder receives such notice. In any case, failure to give such Redemption Notice by mail (or otherwise) or any defect in the Redemption Notice to the Holder of any Note designated for redemption as a whole or in part
shall not affect the validity of the proceedings for the redemption of any other Note. 
 (c) Each Redemption Notice shall
specify: 
 (i) the Redemption Date; 

(ii) the Redemption Price; 
 (iii) that on the Redemption Date, the Redemption Price will become due and payable upon each Note to be redeemed, and that interest thereon, if any, shall cease to accrue on and after the Redemption

the Business Day immediately preceding the Redemption Date;

 62 

 Any Redemption Notice shall be irrevocable. If any of the Notes are evidenced by Global Securities, the
Redemption Notice must comply with appropriate Depositary procedures. 
 (d) If fewer than all of the Outstanding Notes are to
be redeemed, the Trustee shall select the Notes or portions thereof of evidenced by a Global Security or the Notes evidenced by Individual Securities to be redeemed (in principal amounts of $1,000 or multiples thereof) by lot, on a pro rata
basis or by another method the Trustee considers to be fair and appropriate. If any Note selected for partial redemption is submitted for conversion in part after such selection, the portion of the Note submitted for conversion shall be deemed (so
far as may be possible) to be the portion selected for redemption. 
 (e) If any Note is redeemed in part only, then, upon
surrender of such Note, the Company shall issue a new Note in principal amount equal to the unredeemed portion thereof. 

Section 12.04. Payment of Notes Called for Redemption. (a) If any Redemption Notice has been given in respect of the
Notes in accordance with Section 12.03, the Notes shall become due and payable on the Redemption Date. 
 (b) Prior to the
open of business on the Redemption Date, the Company shall deposit with the Paying Agent or, if the Company or a Subsidiary of the Company is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 6.03 of the Base
Indenture an amount of cash (in immediately available funds if deposited on the Redemption Date), sufficient to pay the Redemption Price of all of the Notes to be redeemed on such Redemption Date. Subject to receipt of funds by the Paying Agent,
payment for the Notes to be redeemed shall be made on the Redemption Date for such Notes. 
 The Paying Agent shall, promptly after such payment
and upon written demand by the Company, return to the Company any funds in excess of the Redemption Price. 

Section 12.05. Restrictions on Redemption. Notwithstanding anything in this Article 12, no Notes may be redeemed by the
Company on any date if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such date (except in the case of an acceleration resulting from a Default by the Company in the payment of
the Redemption Price with respect to such Notes). The Paying Agent will promptly return to the respective Holders thereof any Notes evidenced by Individual Securities held by it during the acceleration of the Notes (except in the case of an
acceleration resulting from a Default by the Company in the payment of the Redemption Price with respect to such Notes), or any instructions for book-entry transfer of the Notes in compliance with the procedures of the Depositary shall be deemed to
have been cancelled, and, upon such return or cancellation, as the case may be, the Redemption Notice with respect thereto shall be deemed to have been withdrawn.

 [FORM OF REVERSE OF NOTE] 

Stillwater Mining Company 
 1.75% Convertible Senior Note due 2032 
 This Note is one of a duly authorized
issue of Notes of the Company, designated as its 1.75% Convertible Senior Notes due 2032 (the “Notes”), limited to the aggregate principal amount of $396,750,000 all issued or to be issued under and pursuant to a First Supplemental
Indenture (the “First Supplemental Indenture”) dated as of October 17, 2012 between the Company and Law Debenture Trust Company of New York (the “Trustee”), which amends and supplements the Indenture for Debt
Securities dated as of November 29, 2010 between the Company and the Trustee (the “Base Indenture” and, as amended and supplemented by the First Supplemental Indenture and from time to time with respect to the Notes, the
“Indenture”). Reference is hereby made to the Indenture and all indentures supplemental thereto for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and
the Holders of the Notes. Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture. 
 In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of, and interest on, all Notes may be declared, by either the Trustee or Holders of at least
25% in aggregate principal amount of Notes then Outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions and certain exceptions set forth in the Indenture. 

Subject to the terms and conditions of the Indenture, the Company will make all payments and deliveries in respect of the Fundamental
Change Repurchase Price, the Redemption Price, the Repurchase Price and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a Note to a Paying Agent to collect such payments in respect of the Note. The Company
will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. 
 The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the Holders of the Notes, and in certain other circumstances, with the consent of
the Holders of not less than a majority in aggregate principal amount of the Notes at the time Outstanding, evidenced as in the Indenture provided, to execute supplemental indentures modifying the terms of the Indenture and the Notes as described
therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate principal amount of the Notes at the time Outstanding may on behalf of the Holders of all of the Notes waive any past Default
or Event of Default under the Indenture and its consequences. 
 No reference herein to the Indenture and no provision of this
Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to convert Notes validly surrendered by Holders for conversion in accordance with the Indenture or pay or deliver, as the case may be,
the principal (including the Repurchase Price, the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, accrued and unpaid interest on, and the consideration due upon conversion of, this Note at the place, at the
respective times, at the rate and in the lawful money herein prescribed. 

  
 A-5

 The Notes are issuable in registered form without coupons in denominations of $1,000
principal amount and integral multiples thereof. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, Notes may be exchanged for a like aggregate principal
amount of Notes of other authorized denominations, without payment of any service charge but, if required by the Company or Trustee, with payment of a sum sufficient to cover any transfer or similar tax that may be imposed in connection therewith as
a result of the name of the Holder of the new Notes issued upon such exchange of Notes being different from the name of the Holder of the old Notes surrendered for such exchange. 

The Notes shall be redeemable at the Company’s option in accordance with the terms and conditions specified in the Indenture.

 Upon the occurrence of a Fundamental Change, the Holder has the right, at such Holder’s option, to require the Company
to repurchase for cash all of such Holder’s Notes or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change Repurchase Date at a price equal to the Fundamental Change Repurchase Price.

 Each Holder has the right, at such Holder’s option, to require the Company to repurchase for cash on each of
October 15, 2019, October 15, 2024, and October 15, 2029 all of such Holder’s Notes, or any portion thereof (in principal amounts of $1,000 or integral multiples thereof), on each of such dates at a price equal to the
Repurchase Price. 
 Subject to the provisions of the Indenture, the Holder hereof has the right, at its option, during certain
periods and upon the occurrence of certain conditions specified in the Indenture, prior to the close of business on the Business Day immediately preceding the Maturity Date, to convert any Notes or portion thereof that is $1,000 or an integral
multiple thereof, into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, at the Applicable Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture.

 Terms used in this Note and defined in the Indenture are used herein as therein defined.
