authenticated and delivered under the Indenture is initially limited to $360,000,000 (as increased by an amount equal to the aggregate principal amount of any additional Notes purchased by the Underwriters pursuant to the exercise of their

 10 

 Section 2.02. Form of Notes. The Notes and the Trustee’s certificate of
authentication to be borne by such Notes shall be substantially in the respective forms set forth in Exhibit A, the terms and provisions of which shall constitute, and are hereby expressly incorporated in and made a part of the Indenture. To the
extent applicable, the Company and the Trustee, by their execution and delivery of this Supplemental Indenture, expressly agree to such terms and provisions and to be bound thereby. 

Any Global Note may be endorsed with or have incorporated in the text thereof such legends or recitals or changes not inconsistent with
the provisions of the Indenture as may be required by the Custodian or the Depositary, or as may be required to comply with any applicable law or any regulation thereunder or with the rules and regulations of any securities exchange or automated
quotation system upon which the Notes may be listed or traded or designated for issuance or to conform with any usage with respect thereto, or to indicate any special limitations or restrictions to which any particular Notes are subject. 

Any of the Notes may have such letters, numbers or other marks of identification and such notations, legends or endorsements as the
Officer executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of the Indenture, or as may be required to comply with any law or with any rule or regulation made
pursuant thereto or with any rule or regulation of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, or to conform to usage or to indicate any special limitations or restrictions to
which any particular Notes are subject. 
 Each Global Note shall represent such principal amount of the outstanding Notes as
shall be specified therein and shall provide that it shall represent the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from
time to time be increased or reduced to reflect repurchases, cancellations, conversions, transfers or exchanges permitted hereby. Any endorsement of the Global Note to reflect the amount of any increase or decrease in the amount of outstanding Notes
represented thereby shall be made by the Trustee or the Custodian, at the direction of the Trustee, in such manner and upon instructions given by the Holder of such Notes in accordance with the Indenture. Payment of principal (including the
Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, the Global Note shall be made to the Holder of such Note on the date of payment, unless a record date or other means of determining
Holders eligible to receive payment is provided for herein. 
 Section 2.03. Date and Denomination of Notes; Payments of
Interest and Defaulted Amounts. (a) The Notes shall be issuable in registered form without coupons in denominations of $1,000 principal amount and integral multiples thereof. Each Note shall be dated the date of its authentication and shall
bear interest from the date specified on the face of the form of Note attached as Exhibit A hereto. Accrued interest on the Notes shall be computed on the basis of a 360-day year composed of twelve 30-day months.

 (b) The Person in whose name any Note (or its Predecessor Note) is registered on the Note
Register at 5:00 p.m., New York City time, on any Regular Record Date with respect to any Interest Payment Date shall be entitled to receive the interest payable on such Interest Payment Date. Interest shall be payable at the office or agency of the
Company maintained by the Company for such purposes in the United States, which shall initially be the Corporate Trust Office or the office or agency of the Trustee in Minneapolis, Minnesota. The Company shall pay interest (i) on any Physical
Notes (A) to Holders holding Physical Notes having an aggregate principal amount of $5,000,000 or less, by check mailed to the Holders of these Notes at their address as it appears in the Note Register and (B) to Holders holding Physical
Notes having an aggregate principal amount of more than $5,000,000, either by check mailed to such Holders or, upon application by such Holder to the Note Registrar not later than the relevant Regular Record Date, by wire transfer in immediately
available funds to that Holder’s account within the United States, which application shall remain in effect until the Holder notifies, in writing, the Note Registrar to the contrary or (ii) on any Global Note by wire transfer of
immediately available funds to the account of the Depositary or its nominee. 
 (c) Any Defaulted Amounts shall forthwith cease
to be payable to the Holder on the relevant payment date but shall accrue interest per annum at the rate borne by the Notes plus one percent, subject to the enforceability thereof under applicable law, from, and including, such relevant
payment date, and such Defaulted Amounts together with such interest thereon shall be paid by the Company, at its election in each case, as provided in clause (i) or (ii) below: 

(i) The Company may elect to make payment of any Defaulted Amounts to the Persons in whose names the Notes (or their
respective Predecessor Notes) are registered at 5:00 p.m., New York City time, on a special record date for the payment of such Defaulted Amounts, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the
amount of the Defaulted Amounts proposed to be paid on each Note and the date of the proposed payment (which shall be not less than 25 days after the receipt by the Trustee of such notice, unless the Trustee shall consent to an earlier date), and at
the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted Amounts or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date
of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Amounts as in this clause provided. Thereupon the Company shall fix a special record date for the payment of such
Defaulted Amounts which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment, and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Company shall promptly
notify the Trustee of such special record date and the Trustee, in the name and at the expense of the Company, shall cause notice of 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 Note Register, not less than 10 days prior to such special record date. Notice of the proposed payment of such Defaulted Amounts and the special record date therefor having been so
mailed, such Defaulted Amounts shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at 5:00 p.m., New York City time, on such special record date and shall no longer be payable pursuant to the
following clause (ii) of this Section 2.03(c). 

  
 12 

 (ii) The Company may make payment of any Defaulted Amounts in any other
lawful manner not inconsistent with the requirements of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, and upon such notice as may be required by such exchange or automated
quotation system, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 

Section 2.04. Exchange and Registration of Transfer of Notes; Depositary. (a) The Company shall cause to be kept at the
Corporate Trust Office a register (the register maintained in such office or in any other office or agency of the Company designated pursuant to Section 4.02, the “Note Register”) in which, subject to such reasonable
regulations as it may prescribe, the Company shall provide for the registration of Notes and of transfers of Notes. Such register shall be in written form or in any form capable of being converted into written form within a reasonable period of
time. The Trustee is hereby initially appointed the “Note Registrar” for the purpose of registering Notes and transfers of Notes as herein provided. The Company may appoint one or more co-Note Registrars in accordance with
Section 4.02. 
 Upon surrender for registration of transfer of any Note to the Note Registrar or any co-registrar, and
satisfaction of the requirements for such transfer set forth in this Section 2.04, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any
authorized denominations and of a like aggregate principal amount and bearing such restrictive legends as may be required by the Indenture. 
 Notes may be exchanged for other Notes of any authorized denominations and of a like aggregate principal amount, upon surrender of the Notes to be exchanged at any such office or agency maintained by the
Company pursuant to Section 4.02. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes that the Holder making the exchange is entitled to receive, bearing
registration numbers not contemporaneously outstanding. 
 All Notes presented or surrendered for registration of transfer or
for exchange, repurchase or conversion shall (if so required by the Company, the Trustee, the Note Registrar or any co-Note Registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the
Company and duly executed, by the Holder thereof or its attorney-in-fact duly authorized in writing. 
 No service charge shall
be imposed by the Company, the Trustee, the Note Registrar or any co-Note Registrar for any exchange or registration of transfer of Notes, but the Company or the Trustee may require a Holder to pay a sum sufficient to cover any documentary, stamp or
similar issue or transfer tax required by law or permitted pursuant to Section 11.02(d) or Section 11.02(e). 
 None
of the Company, the Trustee, the Note Registrar or any co-Note Registrar shall be required to exchange or register a transfer of (i) any Notes surrendered for conversion or, if a portion of any Note is surrendered for conversion, such portion
thereof surrendered for 

  
 13 

 
conversion, (ii) any Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with Article 12 or (iii) any Notes selected for redemption in
accordance with Article 13. 
 All Notes issued upon any registration of transfer or exchange of Notes in accordance with this
Supplemental Indenture shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under the Indenture as the Notes surrendered upon such registration of transfer or exchange. 

(b) So long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law, all Notes shall be
represented by one or more Registered Global Securities (each, a “Global Note”) registered in the name of the Depositary or the nominee of the Depositary. The transfer and exchange of beneficial interests in a Global Note that does
not involve the issuance of a Physical Note, shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with the Indenture (including the restrictions on transfer set forth herein) and the Applicable Procedures.

 (c) The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints The
Depository Trust Company to act as Depositary with respect to each Global Note. Initially, each Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the
Trustee as custodian for Cede & Co. 
 (d) The seventh paragraph of Section 2.07 of the Base Indenture is hereby
amended and restated in full, with respect to the Notes, to read as follows: 
 “If (i) the Depositary notifies the
Company at any time that the Depositary is unwilling or unable to continue as depositary for the Global Notes and a successor depositary is not appointed within 90 days, (ii) the Depositary ceases to be registered as a clearing agency under the
Exchange Act and a successor depositary is not appointed within 90 days or (iii) an Event of Default with respect to the Notes has occurred and is continuing and a beneficial owner of any Note requests that its beneficial interest therein be
issued as a Physical Note, the Company shall execute, and the Trustee, upon receipt of an Officer’s Certificate and a Company Order for the authentication and delivery of Notes, shall authenticate and deliver (x) in the case of clause
(iii), a Physical Note to such beneficial owner in a principal amount equal to the principal amount of such Note corresponding such beneficial owner’s beneficial interest and (y) in the case of clause (i) or (ii), Physical Notes to
each beneficial owner of the related Global Notes (or a portion thereof) in an aggregate principal amount equal to the aggregate principal amount of such Global Notes in exchange for such Global Notes, and upon delivery of the Global Notes to the
Trustee such Global Notes shall be canceled.” 
 Physical Notes issued in exchange for all or a part of the Global Note
pursuant to this Section 2.04(d) shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. Upon
execution and authentication, the Trustee shall deliver such Physical Notes to the Persons in whose names such Physical Notes are so registered. 

  
 14 

 At such time as all interests in a Global Note have been converted, canceled, repurchased or
transferred, such Global Note shall be, upon receipt thereof, canceled by the Trustee in accordance with the Applicable Procedures. At any time prior to such cancellation, if any interest in a Global Note is exchanged for Physical Notes, converted,
canceled, repurchased or transferred to a transferee who receives Physical Notes therefor or any Physical Note is exchanged or transferred for part of such Global Note, the principal amount of such Global Note shall, in accordance with the
Applicable Procedures, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on the “Schedule of Exchanges of Notes” on such Global Note, by the Trustee or the Custodian, at the direction of the
Trustee, to reflect such reduction or increase. 
 Neither the Company, the Trustee nor any agent of the Company or the Trustee
shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such beneficial
ownership interests. 
 Section 2.05. Mutilated, Destroyed, Lost or Stolen Notes. In addition to the provisions of
Section 2.08 of the Base Indenture, in case any Note that has matured or is about to mature or has been surrendered for required repurchase or is about to be redeemed or is about to be converted in accordance with Article 11 shall become
mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender thereof except in the
case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to
save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, evidence satisfactory to the Company, the Trustee and, if applicable, any Paying
Agent or Conversion Agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof. 
 Section 2.06. Cancellation of Notes Paid, Converted, Etc. The Company shall cause all Notes surrendered for the purpose of payment, repurchase, redemption, registration of transfer or exchange
or conversion, if surrendered to any Person other than the Trustee (including any of the Company’s Agents, Subsidiaries or Affiliates), to be surrendered to the Trustee for cancellation pursuant to Section 2.11 of the Base Indenture. All
Notes delivered to the Trustee shall be canceled promptly by it, and no Notes shall be authenticated in exchange thereof except as expressly permitted by any of the provisions of the Indenture. The Trustee shall dispose of canceled Notes in
accordance with its customary procedures and, after such disposition, shall deliver a certificate of such disposition to the Company, at the Company’s written request in a Company Order. If the Company shall acquire any of the Notes, such
acquisition shall not operate as a redemption, repurchase or satisfaction of the indebtedness represented by such Notes unless and until the same are delivered to the Trustee for cancellation. 

Section 2.07. Additional Notes; Repurchases. The Company may, without the consent of the Holders and notwithstanding
Section 2.01, issue additional Notes hereunder with the same terms (except for any differences in issue price and interest accrued, if any) and as part of the same series as the Notes initially issued hereunder in an unlimited aggregate
principal amount; 

  
 15 

 
provided that if any such additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal income tax purposes, such additional Notes shall have a separate
CUSIP number. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order, an Officer’s Certificate and an Opinion of Counsel, such Officer’s Certificate and Opinion of Counsel to cover such
matters, in addition to those required by Article 10 of the Base Indenture, as the Trustee shall reasonably request. In addition, the Company or its Subsidiaries may, to the extent permitted by law, and directly or indirectly (regardless of whether
such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, whether by the Company or its Subsidiaries or through 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 2.06. 
 ARTICLE 3

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 Supplemental Indenture, 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 2.08 of the Base Indenture, as amended by this Supplemental 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 4.03(d) hereof) 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 at the Maturity Date, any Fundamental Change Repurchase
Date, upon conversion or otherwise, cash or cash, shares of Common Stock or a combination thereof, as applicable, solely to satisfy the Company’s Conversion Obligation, as applicable, 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 an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the
satisfaction and discharge of this Supplemental Indenture have been complied with. Notwithstanding the satisfaction and discharge of this Supplemental Indenture, the obligations of the Company to the Trustee under Section 7.07 of the Base
Indenture hereof shall survive.

Minneapolis, Minnesota. 
 The Company may also from time to time designate as co-Note Registrars one or more other offices or
agencies where the Notes may be presented or surrendered for any or all such purposes 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 United States for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.
The terms “Paying Agent” and “Conversion Agent” include any such additional or other offices or agencies, as applicable. 
 The Company hereby initially designates the Trustee as the Paying Agent, Note Registrar, Custodian and Conversion Agent and the Corporate Trust Office and the office or agency of the Trustee in
Minneapolis, Minnesota, each shall be considered as one such office or agency of the Company for each of the aforesaid purposes. 
 Section 4.03. Provisions as to Paying Agent. (a) If the Company shall appoint a Paying Agent other than the Trustee, the Company will cause such Paying Agent to execute and deliver to the
Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 4.03: 
 (i) that it will hold all sums held by it as such agent for the payment of the principal (including the Redemption Price and/or the Fundamental Change Repurchase Price, if applicable) of, and accrued and

 17 

 (iii) that at any time during the continuance of an Event of Default, upon
request of the Trustee, it will forthwith pay to the Trustee all sums so held in trust. 
 The Company shall, on or before each

(including the Redemption Price and/or the Fundamental Change Repurchase Price, if applicable) or accrued and unpaid interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such
action; provided that if such deposit is made on the due date, such deposit must be received by the Paying Agent by 11:00 a.m., New York City time, on such date.

 (c) Anything in this Section 4.03 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction and discharge of this Supplemental Indenture, or for any
other reason, pay, cause to be paid or deliver to the Trustee all sums or amounts held in trust by the Company or any Paying Agent hereunder as required by this Section 4.03, such sums or amounts to be held by the Trustee upon the trusts herein
contained and upon such payment or delivery by the Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released from all further liability but only with respect to such sums or amounts. 

(d) Any money and shares of Common Stock deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the
payment of the principal (including the Redemption Price and/or the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, any Note and remaining unclaimed for two years after such principal (including the
Redemption Price and/or the Fundamental Change Repurchase Price, if applicable) or interest has become due and payable shall, subject to applicable abandoned property law, be paid to the Company on request of the Company contained in an
Officer’s Certificate, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the
Trustee or such Paying Agent with respect to such trust money and shares of Common Stock, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before
being 

  
 18 

 
required to make any such repayment, may at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and
of general circulation in The Borough of Manhattan, The City of New York, notice that such money and shares of Common Stock remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such
publication, any unclaimed balance of such money and shares of Common Stock then remaining will be repaid or delivered to the Company. 
 Section 4.04. Existence. Subject to Article 10, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence. 

Section 4.05. Reports by The Company. This Section 4.05 shall supersede Section 4.05 of the Base Indenture and all
references in the Base Indenture to Section 4.05 shall be deemed, for the purposes of the Notes, to be references to this Section 4.05. The Company shall file with the Trustee within 15 days after the same are required to be filed with the
Commission, copies of any documents or reports that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act (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 Commission via the Commission’s EDGAR system (or any successor system) and that are freely available to the public without charge shall be deemed to be filed with the Trustee for purposes
of this Section 4.05 at the time such documents are filed via the EDGAR system (or any successor system); provided that the Trustee shall have no obligation to determine whether or not any such information, documents or reports have been
so filed or are available. 
 Delivery of such reports, information and documents described in this Section 4.05 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 rely exclusively on Officer’s Certificates). 
 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. This Section 4.07 shall supersede Section 4.04 of
the Base Indenture and all references in the Base Indenture to Section 4.04 shall be deemed, for the purposes of the Notes, to be references to this Section 4.07. The Company shall deliver to the Trustee within 120 days after the end of
each fiscal year of the Company (beginning with the fiscal year ending on December 31, 2012) an Officer’s Certificate stating whether or not the signers thereof have knowledge of any failure by the Company to comply with all conditions and
covenants then required to be performed under the Indenture and, if so, specifying each such failure and the nature thereof. 

  
 19 

 In addition, the Company shall deliver to the Trustee, as soon as possible, and in any event
within 30 days after the Company becomes aware of the occurrence of any Event of Default or Default, an Officer’s Certificate setting forth the details of such Event of Default or Default, its status and the action that the Company is taking or
proposes to take with respect thereto.

Section 5.01. Applicability of Article 6 of the Base Indenture. Article 6 of the Base Indenture shall not apply to the Notes.
Instead, the provisions set forth in this Article 5 shall, with respect to the Notes, supersede in its entirety Article 6 of the Base Indenture and all references in the Base Indenture to Article 6 thereof and the provisions therein, as the case may
be, shall, with respect to the Notes, be deemed to be references to this Article 5 and the provisions set forth in this Article 5. All references in the Base Indenture to Section 6.01(d) or Section 6.01(e) thereof and the provisions

in the Base Indenture to Section 6.05 thereof and the provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to Section 5.10 of this Supplemental Indenture and the provisions set forth therein.

to the Notes: 
 (a) default in any payment of interest on any Note when due and payable and the default continues for a period
of 30 days;

 20 

 (g) default by the Company or any Subsidiary of the Company with respect to any mortgage,
agreement or other instrument under which there may be outstanding, or by which there may be secured or evidenced, any indebtedness for money borrowed in excess of $25.0 million (or the foreign currency equivalent thereof) in the aggregate of the
Company and/or any such Subsidiary, whether such indebtedness now exists or shall hereafter be created (i) resulting in such indebtedness becoming or being declared due and payable or (ii) constituting a failure to pay the principal or
interest of any such debt when due and payable at its stated maturity, upon required repurchase, upon redemption or upon declaration of acceleration, in each case, after giving effect to any applicable grace period and if such indebtedness has not
been discharged or such acceleration or required repurchase has not been rescinded or annulled within 30 days, as applicable; 

(h) 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 admit in writing its inability to pay its debts generally as they become due; or 

(i) 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 5.03. Acceleration; Rescission and Annulment. In case 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 5.02(h) or Section 5.02(i) with respect to the Company or any of its Significant Subsidiaries), 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 2.09 of the Base
Indenture, 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 in the Indenture or in the Notes contained to the contrary notwithstanding. If an Event of Default specified in Section 5.02(h) or Section 5.02(i) with

  
 21 

 
respect to the Company or any of its Significant Subsidiaries occurs and is continuing, 100% of the principal of, and accrued and unpaid interest, if any, on, all Notes shall become and shall
automatically be due and payable immediately. 
 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 7.07 of the Base Indenture, and if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction, (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 5.10, and (3) all amounts owing to the Trustee shall have
been paid, 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 of, or accrued and unpaid interest on, any Notes, (ii) a failure to repurchase any
Notes when required or (iii) a failure to pay or deliver, as the case may be, the consideration due upon conversion of the Notes. 
 Section 5.04. Additional Interest. Notwithstanding anything in the Indenture or in the Notes to the contrary, to the extent the Company 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 Trust Indenture Act any documents or reports that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of
the Exchange Act or (ii) the Company’s failure to comply with its obligations as set forth in Section 4.05 hereof shall, 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 (a) 0.25% per annum of the principal amount of the Notes outstanding for each day during the 90-day period beginning on, and including the date on which such Event of Default first occurs and on which such
Event of Default is continuing and (b) 0.50% per annum of the principal amount of the Notes outstanding for each day during the 90-day period beginning on, and including, the 91st day following, and including, the date on which such an
Event of Default first occurs and on which such Event of Default is continuing. If the Company so elects, such Additional Interest shall be payable in the same manner and on the same dates as regular interest on the Notes. On the 181st day after
such Event of Default first occurs (if the Event of Default relating to the Company’s failure to file is not cured or waived prior to such 

  
 22 

 
181st day), the Notes will be subject to acceleration as provided in Section 5.03. In the event that (A) the Company does not elect to pay Additional Interest following an Event of
Default in accordance with this Section 5.04 or (B) the Company does elect to make such payment but does not pay the Additional Interest when due, then in each such case, the Notes shall be subject to acceleration as provided in
Section 5.03. 
 In order to elect to pay Additional Interest as the sole remedy during the first 180 days after the
occurrence of any 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 prior to the beginning of such 180-day period. Upon the failure
to timely give such notice, the Notes shall be immediately subject to acceleration as provided in Section 5.03. 

Section 5.05. Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause (a) or (b) of
Section 5.02 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 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 7.07 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 5.05, 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 7.07 of the Base Indenture; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is

  
 23 

 
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 7.07 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. The Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other similar committee. 

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 5.10 or any rescission and annulment pursuant to Section 5.03 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 5.06. Application of Monies Collected by
Trustee. After an Event of Default, any monies or properties distributable in respect of the Company’s obligations under the Indenture, or any monies collected by the Trustee pursuant to this Article 5 with respect to the Notes shall be
applied in the order following, 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 7.07 of the Base Indenture; 

  
 24 

 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, 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 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 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 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 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 5.07. Proceedings by Holders. Except to enforce the right to receive
payment of principal (including, if applicable, Redemption Price or the Fundamental Change Repurchase Price) or interest when due, or the right to 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 such security or indemnity reasonably satisfactory to it 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 indemnity, shall have failed to institute any such action, suit or proceeding; and 

  
 25 

 (e) no direction that, in the opinion of the Trustee, 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 5.10, 

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 by virtue of or by availing of any provision of the Indenture to affect, disturb or prejudice the rights of any other Holder, or 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 5.07, each and every Holder and the Trustee shall be entitled to such relief as can be given either at law or in equity. 
 Notwithstanding any other provision of the Indenture and any provision of any Note, the right of any Holder to receive payment or delivery, as the case may be, of (x) the principal (including the
Redemption Price or 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 5.08. 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 5.09. Remedies Cumulative and Continuing. Except as provided in the
penultimate paragraph of Section 2.08 of the Base Indenture, as amended by this Supplemental Indenture, all powers and remedies given by this Article 5 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 5.07, every power and remedy given by this Article 5 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. 

  
 26 

 Section 5.10. 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 2.09 of the Base Indenture 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 (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not any such directions are unduly prejudicial to such Holders) 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 2.09 of the Base Indenture 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 or Redemption Price) of, the Notes when due that has not
been cured pursuant to the provisions of Section 5.02, (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 9 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 5.10, 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. 
 Section 5.11. 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 Note 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, except in
the case of a Default in the payment of the principal (including the Fundamental Change Repurchase Price or the Redemption Price, if applicable) of, 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 determine that the withholding of such notice is in the interests of the
Holders. 
 Section 5.12. 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 5.12 (to the extent permitted by law) shall not apply to any
suit instituted by the Trustee, to any 

  
 27 

 
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 2.09
of the Base Indenture, 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 with
respect to the Notes being repurchased as provided in this Supplemental 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 11. 
 ARTICLE 6 
 CONCERNING THE TRUSTEE 

Section 6.01. Duties and Responsibilities of Trustee. In addition to the provisions of Article 7 of the Base Indenture, the
Trustee, prior to the occurrence of an Event of Default and after the curing or waiver of all Events of Default that may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in the Indenture. In case an
Event of Default has occurred that has not been cured or waived the Trustee shall exercise such of the rights and powers vested in it by the Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise
or use under the circumstances in the conduct of such person’s own affairs. 
 (a) No provision of the Indenture shall be
construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that: 
 (i) prior to the occurrence of an Event of Default and after the curing or waiving of all Events of Default that may have occurred, the duties and obligations of the Trustee shall be determined solely by
the express provisions of the Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in the Indenture and no implied covenants or obligations shall be read into the
Indenture against the Trustee; and 
 (ii) in the absence of bad faith and willful misconduct on the part of the
Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of the Indenture; but,
in the case of any such certificates or opinions that by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the
requirements of the Indenture (but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein); 
 (b) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or Officers of the Trustee, unless it shall be proved that the Trustee was negligent in
ascertaining the pertinent facts; 

  
 28 

 (c) the Trustee shall not be liable with respect to any action taken or omitted to be taken
by it in good faith in accordance with the direction of the Holders of not less than a majority of the aggregate principal amount of the Notes at the time outstanding determined as provided in Section 2.09 of the Base Indenture relating to the
time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under the Indenture;

correctness of amount, entitlement to receive or any other matters relating to payment) or notice effected by the Company or any Paying Agent or any records maintained by any co-Note Registrar with respect to the Notes; 

(f) if any party fails to deliver a notice relating to an event the fact of which, pursuant to the Indenture, requires notice to be sent
to the Trustee, the Trustee may conclusively rely on its failure to receive such notice as reason to act as if no such event occurred, unless such Responsible Officer of the Trustee had actual knowledge of such event; 

(g) the Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company;
and 
 (h) in the event that the Trustee is also acting as Custodian, Note Registrar, Paying Agent, Conversion Agent or transfer

Agent, 

  
 29 

 
Conversion Agent or Note Registrar. However, in the event that the Trustee acquires any conflicting interest as defined in Section 310(b) of the Trust Indenture Act, it must eliminate such
conflict within 90 days, apply to the Commission for permission to continue as Trustee or resign. The rights, privileges, protections, immunities and benefits given to the Trustee, including without limitation its right to be compensated,

ARTICLE 7 

CONCERNING THE HOLDERS 

Section 7.01. Action by Holders. Whenever in the Indenture it is provided that the Holders of a specified percentage of the
aggregate principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action, the
Holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Holders in person or by agent or proxy appointed in writing, or (b) by the record of
the Holders voting in favor thereof at any meeting of Holders duly called and held in accordance with the provisions of Article 8 hereof, or (c) by a combination of such instrument or instruments and any such record of such a meeting of
Holders. Whenever the Company or the Trustee solicits the taking of any action by the Holders of the Notes, the Company or the Trustee may fix, but shall not be required to, in advance of such solicitation, a date as the record date for determining
Holders entitled to take such action. The record date if one is selected shall be not more than fifteen days prior to the date of commencement of solicitation of such action. 
 Section 7.02. Proof of Execution by Holders. Subject to the provisions of Section 6.01 hereof, Section 7.02 of the Base Indenture and Section 8.05 hereof, proof of the execution
of any instrument by a Holder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The holding of
Notes shall be proved by the Note Register or by a certificate of the Note Registrar. The record of any Holders’ meeting shall be proved in the manner provided in Section 8.06 hereof. 

Section 7.03. Who Are Deemed Absolute Owners. The Company, the Trustee, any authenticating agent, any Paying Agent, any
Conversion Agent and any Note Registrar may deem the Person in whose name a Note shall be registered upon the Note Register to be, and may treat it as, the absolute owner of such Note (whether or not such Note shall be overdue and

  
 30 

 
notwithstanding any notation of ownership or other writing thereon made by any Person other than the Company or any Note Registrar) for the purpose of receiving payment of or on account of the
principal of and (subject to Section 2.03) accrued and unpaid interest on such Note, for conversion of such Note and for all other purposes; and neither the Company nor the Trustee nor any Paying Agent nor any Conversion Agent nor any Note
Registrar shall be affected by any notice to the contrary. All such payments or deliveries so made to any Holder for the time being, or upon its order, shall be valid, and, to the extent of the sums or shares of Common Stock so paid or delivered,
effectual to satisfy and discharge the liability for monies payable or shares deliverable upon any such Note. Notwithstanding anything to the contrary in the Indenture or the Notes following an Event of Default, any Holder of a beneficial interest
in a Global Note may directly enforce against the Company, without the consent, solicitation, proxy, authorization or any other action of the Depositary or any other Person, such Holder’s right to exchange such beneficial interest for a Note in
certificated form in accordance with the provisions of the Indenture. 
 Section 7.04. Revocation of Consents; Future
Holders Bound. At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 7.01, of the taking of any action by the Holders of the percentage of the aggregate principal amount of the Notes specified in the
Indenture in connection with such action, any Holder of a Note that is shown by the evidence to be included in the Notes the Holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office
and upon proof of holding as provided in Section 7.02, revoke such action so far as concerns such Note. Except as aforesaid, any such action taken by the Holder of any Note shall be conclusive and binding upon such Holder and upon all future
Holders and owners of such Note and of any Notes issued in exchange or substitution therefor or upon registration of transfer thereof, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or
substitution therefor or upon registration of transfer thereof.

 Any record so signed and verified shall be conclusive evidence of the matters therein stated. 

Section 8.07. No Delay of Rights by Meeting. Nothing contained in this Article 8 shall be deemed or construed to authorize or
permit, by reason of any call of a meeting of Holders or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay in the exercise of any right or rights conferred upon or reserved to the Trustee or to the
Holders under any of the provisions of the Indenture or of the Notes.

 Upon the written request of the Company, the Trustee is hereby authorized to join with the Company in
the execution of any such supplemental indenture, to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to, but may in its discretion, enter into any supplemental indenture
that affects the Trustee’s own rights, duties or immunities under the Indenture or otherwise. 
 Any supplemental indenture
authorized by the provisions of this Section 9.02 may be executed by the Company and the Trustee without the consent of the Holders of any of the Notes at the time outstanding, notwithstanding any of the provisions of Section 9.03.

exchange offer for, Notes), the Company and the Trustee, at the Company’s expense, may from time to time and at any time enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any
manner or eliminating any of the provisions of the Indenture or any supplemental indenture or of modifying in any manner the rights of the Holders; provided, however, that, without the consent of each Holder of an outstanding Note

the Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture. 
 Holders do not need under Section 9.02 or Section 9.03 to approve the particular form of any proposed supplemental indenture. It shall be sufficient if such Holders approve the substance
thereof. After any such supplemental indenture becomes effective, the Company shall deliver to the Holders a notice briefly describing such supplemental indenture. However, the failure to give such notice to all the Holders, or any defect in the
notice, will not impair or affect the validity of the supplemental indenture.

conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of the Indenture for any and all purposes.

 Section 9.05. Notation on Notes. Notes authenticated and delivered after the
execution of any supplemental indenture pursuant to the provisions of this Article 9 may, at the Company’s expense, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company or

outstanding.

SALE, CONVEYANCE AND LEASE 
 Section 10.01. Applicability
of Article 5 of the Base Indenture. Article 5 of the Base Indenture shall not apply to the Notes. Instead, the provisions set forth in this Article 10 shall, with respect to the Notes, supersede in its entirety Article 5 of the Base Indenture
and all references in the Base Indenture to Article 5 thereof and the provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to this Article 10 and the provisions set forth in this Article 10.

the Company shall not consolidate with, merge with or into, or sell, convey, transfer or lease all or substantially all of its properties and assets to another 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; and 

(b) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing under the
Indenture.

the properties and assets of one or more Subsidiaries of the Company to another Person, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of the
Company on a consolidated basis, shall be deemed to be the sale, conveyance, transfer or lease of all or substantially all of the properties and assets of the Company to another Person. 

  
 36 

 Section 10.03. Successor Corporation to Be Substituted. In case of any such
consolidation, merger, sale, conveyance, transfer or lease and upon the assumption by the Successor 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 be substituted for the Company, with the same effect as if it had been named herein as the party of the first part,
except in the case of a lease of all or substantially all of the Company’s properties and assets. 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 an Officer 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, merger, sale, conveyance or transfer (but not in the case of
a lease), upon compliance with this Article 10 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 10) 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, merger, sale, conveyance, transfer or lease, 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 10.04. Opinion of
Counsel to Be Given to Trustee. No consolidation, merger, sale, conveyance, transfer or lease shall be effective unless the Trustee shall receive an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any such
consolidation, merger, sale, conveyance, transfer or lease 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 10.

 ARTICLE 11 
 CONVERSION OF NOTES 

Section 11.01. Conversion Privilege. Subject to and upon compliance with the provisions of this Article 11, 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 at any time prior to 5:00 p.m., New York City time, on
the second Scheduled Trading Day immediately preceding the Maturity Date at an initial conversion rate of 83.3333 shares of Common Stock (subject to adjustment as provided in Section 11.04, the “Conversion Rate”) per $1,000
principal amount of Notes (subject to the settlement provisions of Section 11.02, the “Conversion Obligation”). 
 If the Company calls any or all of the Notes for redemption pursuant to Article 13, then Holders may surrender Notes that have been so called for redemption at any time prior to 5:00 p.m., New York City
time, on the Scheduled Trading Day immediately preceding the Redemption Date. 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 its
Notes until the Redemption Price has been paid or duly provided for. 
 Section 11.02. Conversion Procedure; Settlement
Upon Conversion. 
 (a) Subject to this Section 11.02, Section 11.03(b) and Section 11.07(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, together with cash,
if applicable, in lieu of any fractional share of Common Stock in accordance with subsection (j) of this Section 11.02 (“Physical Settlement”) or a combination of cash and shares of Common Stock, together with cash, if
applicable, in lieu of any fractional share of Common Stock in accordance with subsection (j) of this Section 11.02 (“Combination Settlement”), at its election, as set forth in this Section 11.02. 

(i) All conversions occurring on or after the 25th Scheduled Trading Day immediately preceding the Maturity Date, and all
conversions occurring after the Company’s issuance of a Redemption Notice with respect to the Notes and prior to 5:00 p.m., New York City time, on the Scheduled Trading Day immediately preceding the related Redemption Date, shall be settled
using the same Settlement Method. 
 (ii) With respect to conversions occurring prior to the 25th Scheduled
Trading Day immediately preceding the Maturity Date (except conversions occurring after the Company’s issuance of a Redemption Notice with respect to the Notes and prior to 5:00 p.m., New York City time, on the Scheduled Trading Day immediately
preceding the related Redemption Date) the Company shall use the same Settlement Method for all conversions occurring on the same 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. 

  
 38 

 (iii) If, in respect of any Conversion Date (or (x) the period
beginning on, and including, the 25th Scheduled Trading Day immediately preceding the Maturity Date and ending at 5:00 p.m., New York City time, on the second Scheduled Trading Day immediately preceding the Maturity Date or (y) the period
beginning on, and including, the date on which the Company issues a Redemption Notice with respect to the Notes and ending at 5:00 p.m., New York City time, on the Scheduled Trading Day immediately preceding the related Redemption Date, as the case
may be), the Company elects to deliver a notice (the “Settlement Notice”) of the relevant Settlement Method in respect of such Conversion Date (or such period, as the case may be), the Company, through the Trustee, shall deliver
such Settlement Notice to converting Holders no later than 5:00 p.m., New York City time, on the second Trading Day immediately following the relevant Conversion Date (or, in the case of any conversions occurring (x) after the date of issuance
of a Redemption Notice with respect to the Notes and prior to the related Redemption Date, in such Redemption Notice or (y) on or after the 25th Scheduled Trading Day immediately preceding the Maturity Date, no later than the 25th Scheduled
Trading Day immediately preceding the Maturity Date). If the Company does not elect a Settlement Method for a conversion prior to the deadline set forth in the immediately preceding sentence, the Company shall no longer have the right to elect Cash
Settlement or Physical Settlement for such conversion and the Company shall be deemed to have elected Combination Settlement in respect of its Conversion Obligation, and the Specified Dollar Amount per $1,000 principal amount of Notes shall be equal
to $1,000. Such 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. If the Company delivers a Settlement
Notice electing Combination Settlement in respect of its Conversion Obligation prior to the deadline set forth in the second immediately preceding sentence but does not indicate a Specified Dollar Amount in such Settlement Notice, the Specified
Dollar Amount shall be deemed to be $1,000. 
 (iv) The cash, shares of Common Stock or combination of cash and
shares of Common Stock in respect of any conversion of Notes (the “Settlement Amount”) shall be computed as follows: 
 (A) if the Company elects 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 Conversion Rate in effect on the Conversion Date; 
 (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 Observation Period; and

 (C) if the Company elects (or is deemed to have elected) 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 Observation Period. 
 (v) The Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable) shall be determined by the Company promptly following the last day of the Observation Period. Promptly
after such determination of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and 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 Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and 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 11.02(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 Global Note, comply with the Applicable Procedures 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 11.02(h) and (ii) in the case of a Physical Note (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 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 11.02(h). The Trustee (and if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article 11 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 Fundamental Change Repurchase Notice to the Company in respect of such Notes and not validly withdrawn such Fundamental Change
Repurchase Notice in accordance with Section 12.02. 
 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 5:00 p.m., New York City time, on the date (the
“Conversion Date”) that the Holder has complied with the requirements set forth in subsection (b) above. Except as provided in Section 11.03(b) and Section 11.07(a), the Company shall pay or deliver, as the case may
be, the consideration due in 

  
 40 

 
respect of the Conversion Obligation on the third Business Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement, or on the third Business Day
immediately following the last Trading Day of the Observation Period, in the case of any other Settlement Method. 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. 
 (d) In case any Note shall be surrendered for partial conversion, the Company shall
cause the principal balance of a Global Note to be adjusted in accordance with the Applicable Procedures, or 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. 
 (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 11.04, no adjustment shall be made for dividends on any shares issued upon the conversion of any Note as provided in this Article 11. 
 (g) Upon the conversion of an interest in a Global Note, the Trustee, or the Custodian at the direction of the Trustee, shall make a notation on the “Schedule of Exchanges of Notes” to such
Global 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, a Holder shall not receive any separate cash payment for accrued and unpaid interest, if any, except as set forth
below. 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, if Notes are converted after 5:00 p.m., New York City time, on a Regular Record Date,
Holders of such Notes as of 5:00 p.m., New York City time, 

  
 41 

 
on such Regular Record Date will receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for
conversion during the period from 5:00 p.m., New York City time, on any Regular Record Date to 9:00 a.m., New York City time, on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of interest payable on
the Notes so converted; provided that no such payment shall be required (1) for conversions following the Regular Record Date immediately preceding the Maturity 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) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the Business Day immediately
following the corresponding Interest Payment Date; or (4) to the extent of any Defaulted Amounts, if any Defaulted Amounts exists at the time of conversion with respect to such Note. 

(i) Each conversion shall be deemed to have been effected as to any Notes surrendered for conversion as of the Conversion Date;
provided, however, that the Person in whose name the certificate for any shares of Common Stock shall be issuable upon such conversion is registered shall be treated as a stockholder of record as of 5:00 p.m., New York City time, on the
relevant Conversion Date (if the Company elects to satisfy the related Conversion Obligation by Physical Settlement) or the last Trading Day of the relevant Observation Period (if the Company elects (or is deemed to have elected) to satisfy the
related Conversion Obligation by Combination Settlement), as the case may be. 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 on the relevant Conversion Date (in the case of Physical Settlement) or based on the Daily VWAP on the last Trading Day of the relevant Observation Period (in the
case of Combination Settlement). For each Note surrendered for conversion, if the Company has elected (or is deemed to have elected) Combination Settlement, the full number of shares that shall be issued upon conversion thereof shall be computed on
the basis of the aggregate Daily Settlement Amounts for the applicable Observation Period and any fractional shares remaining after such computation shall be paid in cash. 
 Section 11.03. Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Changes. (a) If the Effective Date of a Make-Whole Fundamental
Change occurs prior to the Maturity Date and a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change, the Company shall, under the circumstances described below, increase the Conversion Rate for the Notes so
surrendered for conversion by a number of additional shares of Common Stock (the “Additional Shares”), as described below. A conversion of Notes shall be deemed for these purposes to be “in connection with” such Make-Whole
Fundamental Change if the relevant Notice of Conversion is received by the Conversion Agent from, and including, the Effective Date of the Make-Whole Fundamental Change up to, and including, 5:00 p.m., New York City time, on the Business Day
immediately prior to the related Fundamental Change Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the proviso in clause (b) of the definition thereof, the 35th
Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change). For the avoidance of doubt, the Company shall not increase the Conversion Rate pursuant to this Section 11.03 on account of an anticipated Fundamental
Change that does not occur. 

  
 42 

 (b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental
Change, the Company shall, at its option, satisfy the related Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with Section 11.02, based on the Conversion Rate as increased to reflect the
Additional Shares pursuant to the table set forth below; provided, however, that if, at the effective time of a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Reference Property
is composed entirely of cash, for any conversion of Notes following the Effective Date of such Make-Whole Fundamental Change, 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 Conversion Rate (including any adjustment for Additional Shares), multiplied by such Stock Price. In such event, the Conversion Obligation shall be paid to Holders
in cash on the third Business Day following the Conversion Date. The Company shall notify the Holders of Notes and the Trustee of the Effective Date of any Make-Whole Fundamental Change and issue a press release announcing such Effective Date no
later than five Business Days after such Effective Date. 
 (c) The number of Additional Shares, if any, by which the Conversion
Rate shall be increased shall be determined by reference to the table below, based on the date on which the Make-Whole Fundamental Change 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 Fundamental Change. If the holders of the Common Stock receive only cash in a Make-Whole Fundamental Change described in clause (b) of the definition
of Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the five Trading Day period ending on, and including, the
Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change. The Board of Directors shall make appropriate adjustments to the Stock Price, in its good faith determination, to account for any adjustment to the Conversion
Rate that becomes effective, or any event requiring an adjustment to the 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 Conversion Rate of
the Notes is otherwise adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to such
adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in the table below shall be adjusted in the same manner and at the same time as the
Conversion Rate as set forth in Section 11.04. 

  
 43 

 (e) The following table sets forth the number of Additional Shares to be received per $1,000
principal amount of Notes pursuant to this Section 11.03 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 above 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; 
 (ii) if the Stock Price is greater than $100.00 per share (subject to
adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate; and 

(iii) if the Stock Price is less than $10.00 per share (subject to adjustment in the same manner as the Stock Prices set
forth in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate. 
 Notwithstanding the foregoing, in no event shall the Conversion Rate per $1,000 principal amount of Notes exceed 100.0000 shares of Common Stock, subject to adjustment in the same manner as the Conversion
Rate pursuant to Section 11.04. 
 (f) Nothing in this Section 11.03 shall prevent an adjustment to the Conversion
Rate pursuant to Section 11.04 in respect of a Make-Whole Fundamental Change. 
 (g) For the avoidance of doubt, if a
Holder converts its Notes prior to the Effective Date of any Make-Whole Fundamental Change, then, whether or not such Make-Whole Fundamental Change occurs, such Holder shall not be entitled to an increase in the Conversion Rate pursuant to this
Section 11.03 in connection with such conversion. 
 Section 11.04. Adjustment of Conversion Rate. The
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 adjustments to the Conversion Rate if Holders of the Notes have the right to participate (other than
in the case of a stock 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 11.04, without having
to convert their Notes, as if they held a number of shares of Common Stock equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder. 

  
 44 

 (a) If the Company exclusively issues shares of Common Stock as a dividend or distribution
on shares of its Common Stock, or if the Company effects a share split or share combination, the Conversion Rate shall be adjusted based on the following formula: 
  

 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to 9:00 a.m., New York City time, on the Ex-Dividend Date of such dividend or distribution, or immediately prior to 9:00 a.m., New
York City time, on the Effective Date of such share split or share combination, as applicable;
			
	CR'	  	=	  	the Conversion Rate in effect immediately after 9:00 a.m., New York City time, on such Ex-Dividend Date or Effective Date;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to 9:00 a.m., New York City time, on such Ex-Dividend Date or Effective Date; and
			
	OS'	  	=	  	the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination.

 Any adjustment made under this Section 11.04(a) shall become effective immediately after 9:00 a.m., New York City
time, on the Ex-Dividend Date for such dividend or distribution, or immediately after 9:00 a.m., New York City time, on the Effective Date for such share split or share combination, as applicable. If any dividend or distribution of the type
described in this Section 11.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the 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 its 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 average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance,
the Conversion Rate shall be increased based on the following formula: 
  
 

 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to 9:00 a.m., New York City time, on the Ex-Dividend Date for such
issuance;

  
 45 

					
			
	CR'	  	=	  	the Conversion Rate in effect immediately after 9:00 a.m., New York City time, on such Ex-Dividend Date;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to 9:00 a.m., New York City time, on such Ex-Dividend Date;
			
	X	  	=	  	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
			
	Y	  	=	  	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Last Reported Sale
Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the issuance of such rights, options or warrants.

 Any increase made under this Section 11.04(b) shall be made successively whenever any such rights, options or
warrants are issued and shall become effective immediately after 9:00 a.m., New York City time, 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 Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares
of Common Stock actually delivered. If such rights, options or warrants are not so issued, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such Ex-Dividend Date for such issuance had not occurred.

 For purposes of this Section 11.04(b), 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 such average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day
immediately preceding the date of announcement for such issuance, and in determining the aggregate offering price of such shares of Common Stock, 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, 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 or 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 11.04(a) or Section 11.04(b), (ii) dividends or
distributions paid exclusively in cash as to which an adjustment was effected pursuant to Section 11.04(d), and (iii) Spin-Offs as to which the provisions set forth below in this Section 11.04(c) shall apply (any of such shares of
Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire Capital Stock or other securities, the “Distributed Property”), then the Conversion Rate shall be increased based on the
following formula: 
  
 

 

  
 46 

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to 9:00 a.m., New York City time, on the Ex-Dividend Date for such distribution;
			
	CR'	  	=	  	the Conversion Rate in effect immediately after 9:00 a.m., New York City time, on such Ex-Dividend Date;
			
	SP0	  	=	  	the average of the Last Reported 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 on the Ex-Dividend Date for
such distribution.

 Any increase made under the portion of this Section 11.04(c) above shall become effective
immediately after 9:00 a.m., New York City time, on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such
distribution had not been declared. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, 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 Conversion Rate in effect on the Ex-Dividend Date for the distribution. If the Board of Directors determines the “FMV” (as defined above) of any distribution for purposes of this Section 11.04(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 Last Reported 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. 

  
 47 

 With respect to an adjustment pursuant to this Section 11.04(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 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 Conversion Rate shall be increased based on the following formula: 
  

 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the end of the Valuation Period;
			
	CR'	  	=	  	the Conversion Rate in effect immediately after the end of the Valuation Period;
			
	FMV0	  	=	  	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock
(determined by reference to the definition of Last Reported 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
after, and including, the Ex-Dividend Date of the Spin-Off (the “Valuation Period”); and
			
	MP0	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.

 The adjustment to the Conversion Rate under the preceding paragraph shall occur on the last Trading Day of the Valuation
Period; provided that in respect of any conversion during the Valuation Period, references in the portion of this Section 11.04(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 between the Ex-Dividend Date of such Spin-Off and the Conversion Date in determining the Conversion Rate. In addition, if the Ex-Dividend Date for the Spin-Off is less than 10 Trading Days prior to, and including, the end of the
Observation Period, references in the portion of this Section 11.04(c) related to Spin-Offs to 10 Trading Days shall be deemed to be replaced, solely in respect of that conversion, 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 the Observation Period. 
 For
purposes of this Section 11.04(c) (and subject in all respect to Section 11.11), 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 11.04(c) (and no adjustment to the Conversion Rate under this Section 11.04(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 Conversion Rate shall be made under this Section 11.04(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to
the date of the 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) 

  
 48 

 
with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 11.04(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 Conversion Rate shall be readjusted as if such rights, options
or warrants had not been issued and (y) the 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 Conversion Rate shall be readjusted as if such rights, options
and warrants had not been issued. 
 For purposes of Section 11.04(a), Section 11.04(b) and this
Section 11.04(c), any dividend or distribution to which this Section 11.04(c) is applicable that also includes one or both of: 
 (A) a dividend or distribution of shares of Common Stock to which Section 11.04(a) is applicable (the “Clause A Distribution”); or 

(B) a dividend or distribution of rights, options or warrants to which Section 11.04(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 11.04(c) is applicable (the “Clause C Distribution”) and any Conversion Rate adjustment required by this Section 11.04(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 Conversion Rate adjustment required by Section 11.04(a) and
Section 11.04(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 9:00 a.m., New York City time, on such Ex-Dividend Date
or Effective Date” within the meaning of Section 11.04(a) or “outstanding immediately prior to 9:00 a.m., New York City time, on such Ex-Dividend Date” within the meaning of Section 11.04(b). 

  
 49 

 (d) If any cash dividend or distribution is made to all or substantially all holders of the
Common Stock, the Conversion Rate shall be adjusted based on the following formula: 
  
 

 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to 9:00 a.m., New York City time, on the Ex-Dividend Date for such dividend or distribution;
			
	CR'	  	=	  	the Conversion Rate in effect immediately after 9:00 a.m., New York City time, on the Ex-Dividend Date for such dividend or distribution;
			
	SP0	  	=	  	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and
			
	C	  	=	  	the amount in cash per share the Company distributes to all or substantially all holders of the Common Stock.

 Any increase pursuant to this Section 11.04(d) shall become effective immediately after 9:00
a.m., New York City time, on the Ex-Dividend Date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not to make or
pay such dividend or distribution, to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than
“SP0” (as defined above), in lieu of the foregoing
increase, each Holder of a Note shall receive, 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 Conversion Rate on the Ex-Dividend Date for such cash dividend or distribution. 

(e) If the Company or any of its Subsidiaries make a payment in respect of a tender or exchange offer for the Common Stock, to the extent
that the cash and value of any other consideration included in the payment per share of the Common Stock exceeds the Last Reported Sale Price of the Common Stock on the Trading Day next succeeding the last date on which tenders or exchanges may be
made pursuant to such tender or exchange offer, the Conversion Rate shall be increased based on the following formula: 
  

 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to 5:00 p.m., New York City time, on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the
date such tender or exchange offer expires;
			
	CR'	  	=	  	the Conversion Rate in effect immediately after 5:00 p.m., New York City time, on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date
such tender or exchange offer expires;
			
	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;

  
 50 

					
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires (prior to giving effect to the purchase 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 date such tender or exchange offer expires (after giving effect to the purchase of all shares of Common Stock
accepted for purchase or exchange in such tender or exchange offer); and
			
	SP'	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date
such tender or exchange offer expires.

 The adjustment to the Conversion Rate under this Section 11.04(e) shall occur at 5:00 p.m., New York City time, on
the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that in respect of any conversion within the 10 Trading Days immediately following, and
including, the Trading Day next succeeding the expiration date of any tender or exchange offer, references in this Section 11.04(e) with respect to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed
between the expiration date of such tender or exchange offer and the Conversion Date in determining the Conversion Rate. In addition, if the Trading Day next succeeding the expiration date is less than 10 Trading Days prior to, and including, the
end of the Observation Period, references in this Section 11.04(e) to 10 Trading Days shall be deemed to be replaced, solely in respect of that 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 the Observation Period. 
 If the Company is
obligated to purchase shares of Common Stock pursuant to any such tender or exchange offer, but is permanently prevented by applicable law from effecting all or any such purchases or all or any portion of such purchases are rescinded, the Conversion
Rate shall be decreased to the Conversion Rate that would then be in effect if such tender or exchange offer had been made only in respect of the purchases actually effected. 
 (f) Notwithstanding this Section 11.04 or any other provision of the Indenture or the Notes, if a Conversion Rate adjustment becomes effective on any Ex-Dividend Date, and a Holder that has converted
its Notes on or after such Ex-Dividend Date and on or prior to the related Record Date would be treated as the record holder of the shares of Common Stock as of the related Conversion Date as described under Section 11.02(i) based on an
adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding the Conversion Rate adjustment provisions in this Section 11.04, the Conversion Rate adjustment 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.

 (g) Except as stated herein, the Company shall not adjust the 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. 

  
 51 

 (h) In addition to those adjustments required by clauses (a), (b), (c), (d) and
(e) of this Section 11.04, and to the extent permitted by applicable law and subject to the applicable rules of The New York Stock Exchange, the Company from time to time may increase the Conversion Rate by any amount for a period of at
least 20 Business Days if the Board of Directors determines that such increase would be in the Company’s best interest. In addition, the Company may (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to
holders of Common Stock or rights to purchase Common Stock in connection with a dividend or distribution of shares (or rights to acquire shares) or similar event. Whenever the Conversion Rate is increased pursuant to any of the preceding two
sentences, the Company shall mail to the Holder of each Note at its last address appearing on the Note Register a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the
increased Conversion Rate and the period during which it will be in effect. 
 (i) Notwithstanding anything to the contrary in
this Article 11, the 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; 
 (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 in the par value of the Common
Stock; or 
 (v) for accrued and unpaid interest, if any. 

(j) All calculations and other determinations under this Article 11 shall be made by the Company and shall be made to the nearest one-ten
thousandth (1/10,000th) of a share. The Company shall not be required to make an adjustment in the Conversion Rate unless the adjustment would require a change in the Conversion Rate of at least 1%. However, the Company shall carry forward any
adjustments that are less than 1% of the Conversion Rate and make such carried-forward adjustments, regardless of whether the aggregate adjustment is less than 1%, (i) on December 31 of each calendar year, (ii) upon a Make-Whole
Fundamental Change, and (iii) on the Conversion Date for any conversions of Notes or, with respect to any conversions that occur on or after the 25th Scheduled Trading Day immediately preceding the Maturity Date, on each Trading Day during the
Observation Period for such conversions. 

  
 52 

 (k) Whenever the 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 Conversion Rate 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 Conversion Rate and may assume without inquiry that the last Conversion Rate of which
it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes
effective and shall mail such notice of such adjustment of the Conversion Rate to each Holder at its last address appearing on the Note Register of the Indenture. Failure to deliver such notice shall not affect the legality or validity of any such
adjustment. 
 (l) For purposes of this Section 11.04, 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 11.05. Adjustments of Prices.
Whenever any provision of the Indenture requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts over a span of multiple days (including an Observation Period
and the period for determining the Stock Price for purposes of a Make-Whole Fundamental Change), the Board of Directors shall make appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or any
event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date, Effective Date or expiration date of the event occurs, at any time during the period when the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or
the Daily Settlement Amounts are to be calculated. 
 Section 11.06. 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 11.07. Effect of Recapitalizations, Reclassifications and Changes of the Common Stock. 
 (a) In the case of: 
 (i) any recapitalization, reclassification or
change of the Common Stock (other than changes resulting from a subdivision or combination or a change in the par value of the Common Stock); 
 (ii) any consolidation, merger or combination involving the Company; 

  
 53 

 (iii) any sale, lease or other transfer to a third party of the consolidated
assets of the Company and the Company’s Subsidiaries substantially as an entirety; or 
 (iv) any statutory
share exchange, 
 in each case, as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other
property or assets (including cash or any combination thereof) (any such event, a “Merger Event”), then, at and after the effective time of such Merger Event, the right to convert each $1,000 principal amount of Notes shall be
changed into a right to convert such principal amount of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of Common Stock
equal to the Conversion Rate immediately prior to such Merger Event would have owned or been entitled to receive (the “Reference Property”, with each “unit of Reference Property” meaning the kind and amount of
Reference Property that a holder of one share of Common Stock is entitled to receive) 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 9.02(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 11.02 and (B) (I) any
amount payable in cash upon conversion of the Notes in accordance with Section 11.02 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 11.02 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 been entitled to receive in such Merger Event and (III) the Daily VWAP
shall be calculated based on the value of a unit of Reference Property. 
 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), then (i) the Reference Property into which the Notes will be convertible 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, and (ii) the unit of Reference Property for purposes of the immediately preceding
paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common Stock. If the holders receive only cash in such Merger Event, then for all conversions that occur after the effective date of such Merger
Event (x) the consideration due upon conversion of each $1,000 principal amount of Notes shall be solely cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased by any Additional Shares pursuant to
Section 11.03), multiplied by the price paid per share of Common Stock in such Merger Event and (y) the Company shall satisfy the Conversion Obligation by paying cash to converting Holders on the third Business Day immediately
following the Conversion Date. 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 

  
 54 

 
practicable to the adjustments provided for in this Article 11 (it being understood that no such adjustments shall be required with respect to any portion of the Reference Property that does not
consist of shares of Common Equity). 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 to the extent required by the Board of Directors and practicable the provisions providing for the purchase rights set forth in Article 12. 

(b) In the event the Company shall execute a supplemental indenture pursuant to subsection (a) of this Section 11.07, the
Company shall promptly file with the Trustee an Officer’s Certificate briefly stating the reasons therefore, 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, and shall promptly mail notice thereof to all Holders. The Company shall cause notice of the execution of such supplemental indenture to be mailed
to each Holder, at its address appearing on the Note Register provided for in the Indenture, within 20 days after execution thereof. 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 11.07. 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 11.01 and Section 11.02
prior to the effective date of such Merger Event. 
 (d) The above provisions of this Section shall similarly apply to
successive Merger Events. 
 Section 11.08. 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, to the extent then permitted by the rules and interpretations of the Commission, 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. 

  
 55 

 Section 11.09. Responsibility of Trustee. The Trustee and any other Conversion
Agent shall not at any time be under any duty or responsibility to any Person to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the 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. 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 11.07 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 11.07 or to any
adjustment to be made with respect thereto, but, subject to the provisions of Section 6.01, 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. 

Section 11.10. 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 Conversion Rate pursuant to
Section 11.04 or Section 11.11; 
 (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 Note 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. 

  
 56 

 Section 11.11. 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 stockholder rights plan, as the same may be amended from time to time, unless, prior to any conversion, the rights have separated from the
shares of Common Stock in accordance with the provisions of the applicable stockholder rights plan, in which case the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all or substantially all holders of
Common Stock shares of Capital Stock of the Company, evidences of its indebtedness, other assets or property or rights, options or warrants to acquire its Capital Stock or other securities as provided in Section 11.04(c), subject to
readjustment in the event of the expiration, termination or redemption of such rights. 
 ARTICLE 12 

REPURCHASE OF NOTES AT OPTION OF
HOLDERS 
 Section 12.01. 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 of the principal 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 45 Business Days following the date of the Fundamental Change
Company Notice 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 12. 

(b) Repurchases of Notes under this Section 12.01 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
Notice”) in the form set forth in Attachment 2 to the Form of Note attached hereto as Exhibit A, if the Notes are Physical Notes, or in compliance with the Applicable Procedures if the Notes are Global Notes, in each case on or before 5:00
p.m., New York City time, on the Business Day immediately preceding the Fundamental Change Repurchase Date; and 

  
 57 

 (ii) delivery of the Notes, if the Notes are Physical Notes, to the Paying
Agent at any time after delivery of the Fundamental Change Repurchase Notice (together with all necessary endorsements for transfer) at the Corporate Trust Office of the Paying Agent, or if the Notes are Global Notes, in compliance with the
Applicable Procedures, in each case such delivery being a condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor. 
 The Fundamental Change Repurchase Notice in respect of any Notes to be repurchased shall state: 
 (i) in the case of Physical Notes, the certificate numbers of the Notes to be delivered for repurchase; 
 (ii) the portion of the principal amount of Notes to be repurchased, which must be $1,000 or an integral multiple thereof; and 

(iii) 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 Global Notes, the Fundamental Change Repurchase Notice must comply with the
Applicable Procedures. 
 Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the
Fundamental Change Repurchase Notice contemplated by this Section 12.01 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to 5:00 p.m., New York City time, 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 12.02. 
 The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof. 

(c) On or before the 20th calendar 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 Company 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. Such notice shall be by first class mail or, in the case of Global Notes, in accordance with the Applicable Procedures. Simultaneously with providing such notice,
the Company shall publish a notice containing the information set forth in the Fundamental Change Company Notice in a newspaper of general circulation in The City of New York or publish such information on the Company’s website or through such
other public medium as the Company may use at that time. Each Fundamental Change Company Notice shall specify: 

(i) the events causing the Fundamental Change; 

(ii) the date of the Fundamental Change; 

  
 58 

 (iii) the last date on which a Holder may exercise the repurchase right
pursuant to this Article 12; 
 (iv) the Fundamental Change Repurchase Price; 

(v) the Fundamental Change Repurchase Date; 

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

(vii) if applicable, the Conversion Rate and any adjustments to the Conversion Rate; 

(viii) if applicable, that the Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by a
Holder may be converted only if the Holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of the Indenture; and 
 (ix) the procedures that Holders must follow to require the Company to repurchase their Notes. 
 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 12.01. 
 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. 
 (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 shall promptly return to the respective Holders thereof any Physical Notes 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 Applicable Procedures shall be deemed to have been cancelled, and, upon such return or cancellation, as the case may be,
the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn. 
 (e) Notwithstanding the
foregoing, the Company shall not be required to repurchase any Notes in respect of which the Fundamental Change repurchase right has been exercised pursuant to this Section 12.01 and in respect of which the relevant Fundamental Change
Repurchase Notice has not been withdrawn if a third party purchases such Notes on the Fundamental Change Repurchase Date in the manner and otherwise in compliance with the requirements set forth herein applicable to the repurchase of Notes upon a
Fundamental Change.

 (i) the principal amount of the Notes with respect to which such notice of withdrawal is being submitted, 
 (ii) if Physical Notes have been issued, the certificate numbers of the Notes in respect of which such notice of withdrawal is being submitted, and 

(iii) the principal amount, if any, of any such Note that remains subject to the original Fundamental Change Repurchase
Notice, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000; 
 provided, however, that if the
Notes are Global Notes, the notice must comply and be delivered in accordance with Applicable Procedures. 

Section 12.03. Deposit of Fundamental Change Repurchase Price. (a) The Company shall deposit with the Trustee (or other
Paying Agent appointed by the Company, or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 4.03) on or prior to 11:00 a.m., New York City time, on the Fundamental Change Repurchase

the Company) by the Holder thereof in the manner required by Section 12.01 by mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in the Note 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 Fundamental Change Repurchase Price. 
 (b) If by 11:00 a.m., New York City time, on the Fundamental
Change Repurchase Date, 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 Fundamental Change Repurchase Date, then
(i) such Notes will cease to be outstanding, (ii) interest will cease to accrue on such Notes (whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to the Trustee or Paying Agent) and
(iii) all other rights of the Holders of such Notes will terminate (other than the right to receive the Fundamental Change Repurchase Price). 

  
 60 

 (c) Upon surrender of a Note that is to be repurchased in part pursuant to
Section 12.01, 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.

Base Indenture and all references in the Base Indenture to Article 3 thereof and the provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to this Article 13 and the provisions set forth in this Article
13. 
 Section 13.02. Right to Redeem; Notices to Trustee. No sinking fund is provided for the Notes. The Notes
shall not be redeemable by the Company prior to September 1, 2015. On any Business Day on or after September 1, 2015, the Company may redeem (an “Optional Redemption”) for cash all or part of the Notes, at the Redemption
Price, if the Last Reported Sale Price of the Common Stock has been at least 130% of the Conversion Price then in effect for at least 20 Trading Days (whether or not consecutive), including the Trading Day immediately preceding the date on which the
Company provides the Redemption Notice, during any 30 consecutive Trading Day period ending on the Trading Day prior to the date on which the Company provides the Redemption Notice in accordance with Section 13.03. 

Section 13.03. Notice of Optional Redemption; Selection of Notes. 

(a) In case the Company exercises its Optional Redemption right to redeem all or, as the case may be, any part of the Notes pursuant to
Section 13.02, it shall fix a date for redemption (each, a “Redemption Date”) and it or, at its written request received by the Trustee not less than 55 calendar 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, 

  
 61 

 
shall provide or cause to be provided a notice of such Optional Redemption (a “Redemption Notice”) not less than 40 nor more than 60 calendar 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 Note 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 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 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 Date; 
 (iv) the place or
places where such Notes are to be surrendered for payment of the Redemption Price; 
 (v) that Holders may
surrender their Notes for conversion at any time prior to the 5:00 p.m., New York City time, on the Scheduled Trading Day immediately preceding the Redemption Date; 

(vi) the procedures a converting Holder must follow to convert its Notes and the Settlement Method and Specified Cash
Amount, if applicable; 
 (vii) the Conversion Rate and, if applicable, the number of Additional Shares added to
the Conversion Rate in accordance with Section 11.03; 
 (viii) the CUSIP, ISIN or other similar numbers, if
any, assigned to such Notes; and 
 (ix) in case any Note is to be redeemed in part only, the portion of the
principal amount thereof to be redeemed and on and after the Redemption Date, upon surrender of such Note, a new Note in principal amount equal to the unredeemed portion thereof shall be issued. 

A Redemption Notice shall be irrevocable. 
 (d) If fewer than all of the outstanding Notes are to be redeemed and the Notes are in the form of Global Notes, the Depositary will select the Notes to be redeemed. If fewer than all

  
 62 

 
of the outstanding Notes are to be redeemed and the Notes are in the form of Physical Notes, the Trustee shall select the Notes or portions thereof 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. 

Section 13.04. Payment of Notes Called for Redemption. (a) If any Redemption Notice has been given in respect of the
Notes in accordance with Section 13.03, the Notes shall become due and payable on the Redemption Date at the place or places stated in the Redemption Notice and at the applicable Redemption Price. On presentation and surrender of the Notes at
the place or places stated in the Redemption Notice, the Notes shall be paid and redeemed by the Company at the applicable Redemption Price. 
 (b) Prior to 9:00 a.m., New York City time, 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 6.04 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 promptly after the later of: 
 (i) the Redemption Date for such Notes; and 
 (ii) the time of
presentation of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the manner required by this Section 13.04. 
 Section 13.05. Restrictions on Redemption. The Company may not redeem any Notes on any date if the principal amount of the Notes has been accelerated in accordance with the terms of the
Indenture, and such acceleration has not been rescinded, on or prior to the Redemption 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).

 [FORM OF REVERSE OF NOTE] 

MOLYCORP, INC. 

6.00% Convertible Senior Note due 2017 
 This Note is one of a duly authorized issue of Securities of the Company, designated as its 6.00% Convertible Senior Notes due 2017 (the “Notes”), limited to the aggregate principal
amount of $360,000,000 (as increased by an amount equal to the aggregate principal amount of any additional Notes purchased by the Underwriters pursuant to the exercise of their over-allotment option as set forth in the Underwriting Agreement) all
issued or to be issued under and pursuant to an Indenture dated as of                     , as previously amended and supplemented from time to time
in accordance with the terms thereof (the “Base Indenture”) and as further supplemented by the First Supplemental Indenture dated as of
                     (the “Supplemental Indenture” and, together with the Base Indenture, as supplemented by the Supplemental
Indenture, the “Indenture”), between the Company and Wells Fargo Bank, National Association (the “Trustee”), to which reference is hereby made for a description of the rights, limitations of rights, obligations,
duties and immunities thereunder of the Trustee, the Company and the Holders of the 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 Supplemental Indenture (other than an Event of Default specified in Section 5.02(h)
or Section 5.02(i) with respect to the Company or any of its Significant Subsidiaries), 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. If an Event of Default
specified in Section 5.02(h) or Section 5.02(i) of the Supplemental Indenture with respect to the Company or any of its Significant Subsidiaries occurs and is continuing, 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. 
 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 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. 

  
 A-5

 No reference herein to the Indenture and no provision of this Note or of the Indenture shall
alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal (including the Fundamental Change Repurchase Price, if applicable) of and accrued and unpaid interest on this Note at the place, at the
respective times, at the rate and in the lawful money herein prescribed. 
 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 on any Business Day on or after September 1, 2015 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. 
 Subject to the provisions of the Indenture, the Holder hereof has the right, at
its option, to convert any Notes, or any portion thereof that is $1,000 or an integral multiple thereof, at any time prior to 5:00 p.m., New York City time, on the second Scheduled Trading Day immediately preceding the Maturity Date, into cash,
shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture. 

The terms of the Notes include those stated in the Indenture. 
 Terms used in this Note and defined in the Indenture are used herein as therein defined.

 1Share Lending Agreement

 Exhibit 10.1 
 EXECUTION VERSION 
 SHARE LENDING
AGREEMENT 
 Dated as of August 17, 2012 

Between 

Molycorp, Inc. (“Lender”) 
 and 
 Morgan Stanley Capital Services LLC (“Borrower”) 

 This AGREEMENT sets forth the terms and conditions under which Borrower may, from time to
time, borrow from Lender shares of Common Stock. 
 The parties hereto agree as follows: 

Section 1. Certain Definitions. The following capitalized terms shall have the following meanings: 

“Business Day” means a day on which regular trading occurs in the principal trading market for the Common Stock.

 “Cash” means any coin or currency of the United States as at the time shall be legal tender for payment of
public and private debts. 
 “Clearing Organization” means The Depository Trust Company, or, if agreed to by
Borrower and Lender, such other securities intermediary at which Borrower and Lender maintain accounts. 
 “Closing
Price” on any day means, with respect to the Common Stock (i) if the Common Stock is listed on a national or regional U.S. securities exchange or is included in the OTC Bulletin Board Service (operated by the Financial Industry
Regulatory Authority, Inc.) or any successor thereto, the last reported sale price, regular way, in the principal trading session on such day on such market or service on which the Common Stock is then listed or is included, as the case may be (or,
if the day of determination is not a Business Day, the immediately preceding Business Day), and (ii) if the Common Stock is not so listed or included or if the last reported sale price is not obtainable (even if the Common Stock is listed on
such market or included in such service), the average of the bid prices for the Common Stock obtained from as many dealers in the Common Stock (which may include Borrower or its affiliates), but not exceeding three, as shall furnish bid prices
available to Lender. 
 “Common Stock” means the shares of common stock, par value $0.001 per share, of Lender;
provided that, if the Common Stock shall be exchanged for or converted into any other security, assets and/or other consideration (including cash) as the result of any merger, consolidation, other business combination, reorganization,
reclassification, recapitalization or other corporate action (including, without limitation, a reorganization in bankruptcy), then, effective upon such exchange or conversion, the amount of such other security, assets and/or other consideration
received in exchange for one share of Common Stock shall be deemed to become one share of Common Stock. For purposes of the foregoing, where a share of Common Stock may be converted into or exchanged for more than a single type of consideration
based upon any form of stockholder election, such consideration will be deemed to be the weighted average of the types and amounts of consideration received by the holders of the Common Stock that affirmatively make such an election. 

“Convertible Notes” means (i) up to $360,000,000 aggregate principal amount of 6.00% Convertible Senior Notes due
2017 issued by Lender and (ii) up to $414,000,000 aggregate principal amount of such securities to the extent the option to purchase such additional securities (the “Over-Allotment Option”) is exercised as set forth in the
Underwriting Agreement. 
 “Cutoff Time” shall mean 10:00 a.m. in the jurisdiction of the Clearing
Organization, or such other time on a Business Day by which a transfer of Loaned Shares must be made by Borrower or Lender to the other, as shall be determined in accordance with market practice, in which case such other time will be the
“Cutoff Time.” 
 “Exchange Act” means the Securities Exchange Act of 1934, as amended.

 “Facility Termination Date” means the earliest to occur of (i) the 3rd Business Day (as such term is
defined in the First Supplemental Indenture) immediately following the 23rd Trading Day (as such term is defined in the First Supplemental Indenture) immediately following the date on which all Convertible Notes have been redeemed, repurchased,
converted or otherwise acquired for value, (ii) the date, if any, on which all Loans hereunder are terminated and (iii) the date, if any, on which this Agreement is terminated. 

 “First Supplemental Indenture” means the first supplemental indenture, to
be dated as of August 22, 2012, to be entered into between Lender and Wells Fargo Bank, National Association, a national banking association, as trustee (the “Trustee”), to provide for the form, terms and other provisions of the
Convertible Notes and which shall supplement the base indenture, to be dated as of August 22, 2012, to be entered into between Lender and the Trustee. 
 “Lender’s Designated Account” means the securities account of Lender maintained on the books of Morgan Stanley & Co. LLC, as securities intermediary, and with such
designation as notified by the Lender to the Borrower promptly following the date hereof and in no event later than August 21, 2012. 
 “Loaned Shares” means shares of Common Stock transferred in a Loan hereunder until such Common Stock (or identical Common Stock) is transferred back to Lender hereunder; provided
that, to the extent Borrower subsequently transfers to another transferee shares of Common Stock initially transferred to Borrower hereunder, “Loaned Shares” means an equivalent number of identical shares of Common Stock. If, as the
result of a stock dividend, stock split or reverse stock split, the number of outstanding shares of Common Stock is increased or decreased, then the number of outstanding Loaned Shares shall, effective as of the payment or delivery date of any such
event, be proportionately increased or decreased, as the case may be. If the outstanding shares of Common Stock shall be exchanged for or converted into any new or different security or securities, assets and/or other consideration, as described in
the definition of “Common Stock,” such new or different security or securities, assets and/or other consideration shall, effective upon such exchange or conversion, as the case may be, be deemed to become a Loaned Share in substitution for
the former Loaned Share for which such exchange is made and in the same proportions as described in the definition of “Common Stock.” For purposes of return of Loaned Shares by Borrower or purchase or sale of securities pursuant to
Section 4 or 10, Borrower may return securities of the same issuer, class and quantity as the Loaned Shares as adjusted pursuant to the two preceding sentences. 
 “Maximum Number of Shares” means 13,800,000 shares of Common Stock, subject to adjustment as follows: 
 (a) If, as the result of a stock dividend, stock split or reverse stock split, the number of outstanding shares of Common Stock is increased or decreased, the Maximum Number of Shares shall, effective as
of the payment or delivery date of any such event, be proportionally increased or decreased, as the case may be. 
 (b) If on
September 16, 2012, (i) the Over-Allotment Option has not been exercised, the Maximum Number of Shares shall be reduced by 1,800,000 shares of Common Stock or (ii) the Over-Allotment Option has been exercised only in part, Borrower
shall determine the appropriate adjustment to the Maximum Number of Shares and the date for such adjustment or adjustments in good faith and in a commercially reasonable manner; provided that, in the case of subclause (ii), absent agreement
by Borrower, the Maximum Number of Shares shall in no case be reduced pursuant to this clause to a number of shares of Common Stock (rounded down to the nearest whole share) less than the product of (x) the then-applicable Maximum Number of
Shares, and (y) a fraction, the numerator of which is the aggregate principal amount of Convertible Notes assuming the Over-Allotment Option has not been exercised, and the denominator of which is (A) the aggregate principal amount
of Convertible Notes outstanding as of initial issuance, plus (B) the aggregate principal amount of Convertible Notes that would have been issued if the Over-Allotment Option had been exercised in full, and the date of such adjustment
pursuant to subclause (ii) shall be no earlier than September 16, 2012. 
 (c) If, at any time after
September 16, 2012, the Maximum Number of Shares exceeds the product of (A) the aggregate principal amount of Convertible Notes outstanding at such time (it being understood and agreed, notwithstanding anything to the contrary in the First
Supplemental Indenture, that for purposes of this clause (c), Convertible Notes surrendered for conversion by the holders thereof shall not cease to be outstanding until the day on which the Lender delivers to the relevant converting holder the
consideration due upon conversion), divided by $1,000 and (B) the Conversion Rate (as defined in the First Supplemental Indenture), Lender may so notify Borrower in writing of such fact. Upon receipt of such notice by Borrower, effective
five Business Days following such receipt, the Maximum Number of Shares shall be reduced by such excess. 

 (d) Upon the termination of any Loan pursuant to Section 4(a), the Maximum Number of
Shares shall be reduced by the number of Loaned Shares surrendered by Borrower to Lender, in accordance with a direction of Borrower that Borrower will provide to Lender in connection with any such surrender of Loaned Shares; provided that if
Borrower does not provide any such direction in connection with any such surrender, the Maximum Number of Shares shall be reduced by the number of Loaned Shares so surrendered; and provided further that if the number of Loaned Shares offered
and sold by Borrower in any registered public offering under the Securities Act is less than the number of shares of Common Stock constituting the Loan made in connection with such registered public offering (such difference, the “Unsold
Amount”), any termination of a Loan in an amount equal to the Unsold Amount prior to the date that is 30 calendar days following the date of the Borrowing Notice (as defined below) with respect to such Loan shall not so reduce the Maximum
Number of Shares. 
 “Registration Blackout Period” means (i) the period beginning at
11:59 p.m. on the fourteenth calendar day preceding the last day of each fiscal quarter of Lender and ending at 11:59 p.m. on the second Business Day following the day on which Lender’s quarterly earnings with respect to such fiscal quarter are
publicly announced (or, in the case of the fourth fiscal quarter, if no quarterly earnings are announced, Lender’s annual earnings), and (ii) if, after September 16, 2012, Lender is in possession of material non-public information
about Lender or the Common Stock, the disclosure of which Lender reasonably believes would not be in its best interests, and notifies Borrower of that fact, the period beginning on the day on which Lender provides such notice to Borrower and ending
on the 45th Business Day thereafter; provided that
the aggregate duration of such Registration Blackout Period under clause (ii) above shall not exceed 45 Business Days during the term of this Agreement. 
 “Securities Act” means the Securities Act of 1933, as amended. 

“UCC” means the Uniform Commercial Code as in effect in the State of New York on the date hereof and as it may be
amended from time to time. 
 “Underwriting Agreement” means the Underwriting Agreement, dated as of
August 17, 2012, entered into between Lender and Morgan Stanley & Co. LLC as representative for several underwriters named therein, providing for the public offering of the Common Stock. 

Section 2. Loans Of Shares; Transfers of Loaned Shares 

(a) Subject to the terms and conditions of this Agreement, Lender hereby agrees to make available for borrowing by Borrower shares of
Common Stock up to, in the aggregate, the Maximum Number of Shares. 
 (b) Subject to the terms and conditions of this
Agreement, Borrower may, from time to time, by not less than one Business Day’s written notice to Lender (a “Borrowing Notice”) initiate one or more transactions in which Lender will lend Loaned Shares to Borrower through the
issuance by Lender of such Loaned Shares to Borrower upon the terms, and subject to the conditions, set forth in this Agreement (each such issuance and loan, a “Loan”); provided that Borrower may not initiate a Loan by
delivering a Borrowing Notice to Lender (i) during any Registration Blackout Period or (ii) after the earlier to occur of (A) March 15, 2013 and (B) the date as of which the Maximum Number of Shares shall have been sold
pursuant to the Underwriting Agreement. Such Loan shall be confirmed through the book-entry settlement system of the Clearing Organization. The records maintained by the Clearing Organization shall constitute conclusive evidence with respect to a
Loan, including the number of shares of Common Stock that are the subject of such Loan to which the applicable records relate. 

(c) Notwithstanding anything to the contrary in this Agreement, Borrower shall not be permitted to borrow, and may not initiate a Loan
hereunder with respect to, any shares of Common Stock at any time to the extent (in the case of clause (i) below or to the extent that Borrower determines in its sole discretion (in the case of clause (ii) below) that after receipt of any
shares of Common Stock in connection with such Loan, (i) the Section 16 Percentage would exceed 8.0% or (ii) the Share Amount would exceed the Applicable Share Limit. The “Section 16 Percentage” as of any day is the
fraction, expressed as a percentage, (A) the numerator of which is the number of shares of Common Stock that Borrower and each 

 
person subject to aggregation of shares of Common Stock with Borrower under Section 13 or Section 16 of the Exchange Act and the rules and regulations promulgated thereunder directly or
indirectly beneficially own (as defined under Section 13 or Section 16 of the Exchange Act and the rules and regulations promulgated thereunder) as of such day and (B) the denominator of which is the number of shares of Common Stock
outstanding as of such day. The “Share Amount” as of any day is the number of shares of Common Stock that a Borrower Person under any law, rule, regulation, regulatory order or organizational documents or contracts of Lender that
are, in each case, applicable to ownership of shares of Common Stock (the “Applicable Restrictions”) owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of
ownership under any Applicable Restriction, as determined by Borrower in its reasonable discretion. A “Borrower Person” is Borrower and any person whose ownership position would be aggregated with that of Borrower. The
“Applicable Share Limit” is, as of any day, a number of shares of Common Stock equal to (A) the minimum number of shares of Common Stock that could give rise to materially adverse reporting obligations, materially adverse
registration obligations or other materially adverse requirements (including obtaining prior approval from any person or entity) of a Borrower Person, or could result in an adverse effect on a Borrower Person, under any Applicable Restriction, as
determined by Borrower in its reasonable discretion, minus (B) 1% of the number of shares of Common Stock outstanding as of such day. 
 (d) Lender shall transfer Loaned Shares to Borrower on or before the Cutoff Time on the date specified in the Borrowing Notice for the commencement of the relevant Loan, which date shall not be earlier
than the third Business Day following the receipt by Lender of the Borrowing Notice. Delivery of the Loaned Shares to Borrower shall be made in the manner set forth under Section 11 below. 

Section 3. Loan Fee. Borrower agrees to pay Lender a single loan fee per Loan (a “Loan Fee”) equal to $0.001
per Loaned Share included in such Loan. Such Loan Fee shall be paid by Borrower on or before the time of transfer of the Loaned Shares pursuant to Section 2(d) on a delivery-versus-payment basis through the facilities of the Clearing
Organization. 
 Section 4. Loan Terminations.  

(a) Borrower may terminate all or any portion of a Loan on any Business Day by giving written notice thereof to Lender and transferring
the corresponding number of Loaned Shares to Lender no later than the third Business Day following the date of such notice, without any consideration being payable in respect thereof by Lender to Borrower; provided that such termination shall
not relieve Borrower from the obligation to make such other payments and/or deliveries required to be made by it to Lender hereunder, including any such payments and/or deliveries pursuant to Section 5 hereof. Any such loan termination shall be
effective immediately upon delivery of the Loaned Shares in accordance with the terms hereof. 
 (b) Subject to Section 10
below, all outstanding Loans, if any, shall terminate on the Facility Termination Date, and all Loaned Shares, if any, then outstanding shall be delivered by Borrower to Lender, without any consideration being payable in respect thereof by Lender to
Borrower, no later than the third Business Day following the Facility Termination Date; provided that such termination shall not relieve Borrower from the obligation to make such other payments and/or deliveries required to be made by it to
Lender hereunder, including any such payments and/or deliveries pursuant to Section 5 hereof. 
 (c) Subject to
Section 10 below, if a Loan is terminated upon the occurrence of a Default as set forth in Section 9, the Loaned Shares in respect of such Loan shall be delivered by Borrower to Lender, without any consideration being payable in respect
thereof by Lender to Borrower, no later than the third Business Day following the termination date of such Loan as provided in Section 9; provided that such termination shall not relieve Borrower from the obligation to make such other
payments and/or deliveries required to be made by it to Lender hereunder, including any such payments and/or deliveries pursuant to Section 5 hereof. 
 (d) If at any time the aggregate number of Loaned Shares outstanding under this Agreement exceeds the Maximum Number of Shares, then the outstanding Loans (or portions thereof) to the extent of such
excess shall immediately terminate and, subject to Section 10 below, such excess number of Loaned 

 
Shares in respect of such terminated Loans (or portions thereof) shall be delivered by Borrower to Lender, without any consideration being payable in respect thereof by Lender to Borrower, no
later than the third Business Day following the first date as of which such excess exists; provided that such termination shall not relieve Borrower from the obligation to make such other payments and/or deliveries required to be made by it
to Lender hereunder, including any such payments and/or deliveries pursuant to Section 5 hereof. 
 Section 5.
Distributions.  
 (a) If, at any time when there are Loaned Shares outstanding under this Agreement, Lender pays a cash
dividend or makes a cash distribution in respect of all its outstanding shares of Common Stock, Borrower shall pay to Lender (whether or not Borrower is a holder of any or all of the outstanding Loaned Shares), within three Business Days after the
payment of such dividend or distribution, an amount in cash equal to the product of (i) the amount per share of Common Stock of such dividend or distribution, as the case may be, and (ii) the number of Loaned Shares outstanding at
such time; provided that if Borrower returns any Loaned Shares to Lender following a record date for such a dividend or distribution on such Loaned Shares but prior to the payment of such dividend or distribution on such Loaned Shares,
Borrower shall nonetheless pay to Lender the amount of such dividend or distribution, as the case may be, within three Business Days after the payment of such dividend or distribution. 

(b) If, at any time when there are Loaned Shares outstanding under this Agreement, Lender makes a distribution in respect of all its
outstanding shares of Common Stock (other than a distribution upon liquidation or a reorganization in bankruptcy) in property or securities, including any spin-off securities or assets, options, warrants, rights or privileges in respect of
securities (other than a distribution of Common Stock, but including any spin-off securities or assets, options, warrants, rights or privileges exercisable for, convertible into or exchangeable for Common Stock) (a “Non-Cash
Distribution”), Borrower shall deliver to Lender in kind (whether or not Borrower is a holder of any or all of the outstanding Loaned Shares), within three Business Days after the date of such Non-Cash Distribution, the property or
securities so distributed in an amount (the “Delivery Amount”) equal to the product of (i) the amount per share of Common Stock of such Non-Cash Distribution, and (ii) the number of Loaned Shares outstanding at such
time; provided that if Borrower returns any Loaned Shares to Lender following a record date for such a Non-Cash Distribution on such Loaned Shares but prior to the settlement of such Non-Cash Distribution on such Loaned Shares, Borrower shall
nonetheless deliver to Lender the Delivery Amount in respect of such Non-Cash Distribution within three Business Days after the settlement date of distribution. 
 Section 6. Rights in Respect of Loaned Shares.  
 Subject to the terms
of this Agreement, including Borrower’s obligation to return the Loaned Shares in accordance with the terms of this Agreement, and except as otherwise agreed by Borrower and Lender or Borrower and any subsequent transferee of Loaned Shares,
insofar as such person is the record owner of any such Loaned Shares, such person shall have all of the incidents of ownership in respect of any such Loaned Shares, including the right to transfer the Loaned Shares to others. Borrower agrees that
neither it or any of its affiliates that is the record owner of any Loaned Shares initially transferred hereunder, held for delivery to Lender or held by Borrower or its affiliates (other than any such securities that are held in the accounts of,
and beneficially owned by, any unaffiliated third party, where such third party has the power to, and has, directed the vote of such securities), shall vote such Loaned Shares on any matter submitted to a vote of Lender’s stockholders.

 Section 7. Representations and Warranties.  

(a) Each of Borrower and Lender represent and warrant to the other that: 

(i) it has full power to execute and deliver this Agreement, to enter into any Loans contemplated hereby and to perform
its obligations hereunder; 
 (ii) it has taken all necessary action to authorize such execution, delivery, entry
and performance; 

 (iii) this Agreement constitutes its legal, valid and binding obligation,
enforceable against it in accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors’ rights and remedies generally, and subject, as to
enforceability, to general principles of equity, including principles of commercial reasonableness, good faith and fair dealing (regardless of whether enforcement is sought in a proceeding at law or in equity) and except that rights to
indemnification and contribution hereunder may be limited by federal or state securities laws or public policy relating thereto; and 
 (iv) the execution, delivery and performance of this Agreement does not and will not violate, contravene, or constitute a default under, (A) its certificate of incorporation, bylaws or other
governing documents, (B) any laws, rules or regulations of any governmental authority to which it is subject, (C) any contracts, agreements or instrument to which it is a party or (D) any judgment, injunction, order or decree by which
it is bound. 
 (b) Lender represents and warrants to Borrower, as of the date hereof, and as of the date any Loaned Shares are
transferred to Borrower in respect of any Loan hereunder, that the Loaned Shares in respect of such Loan and all other outstanding shares of Common Stock of Lender have been duly authorized and, upon the issuance (if necessary) and delivery of such
Loaned Shares to Borrower in accordance with the terms and conditions hereof, and subject to the contemporaneous or prior receipt of the applicable Loan Fee by Lender, will be duly authorized, validly issued, fully paid nonassessable shares of
Common Stock, and the stockholders of Lender have no preemptive rights with respect to such Loaned Shares. 
 (c) Lender
represents and warrants to Borrower, as of the date hereof, and as of the date any Loaned Shares are transferred to Borrower in respect of any Loan hereunder, that all of the outstanding shares of Common Stock are listed on The New York Stock
Exchange (“NYSE”) and the Loaned Shares in respect of such Loan have been approved for listing on the NYSE, subject to official notice of issuance. 
 (d) Lender represents and warrants to Borrower, as of the date any Loaned Shares are transferred to Borrower in respect of any Loan hereunder, that Lender is not “insolvent” (as such term is
defined under Section 101(32) of Title 11 of the United States Code (the “Bankruptcy Code”) and Lender would be able to purchase a number of shares of Common Stock equal to the Maximum Number of Shares in compliance with the
corporate law of Lender’s jurisdiction of incorporation. 
 (e) Lender represents and warrants to Borrower that, as of the
date hereof, and as of the date any Loaned Shares are transferred to Borrower in respect of any Loan hereunder, Lender is not, and will not be required to register as, an “investment company” as such term is defined in the Investment
Company Act of 1940, as amended. 
 (f) Lender represents and warrants to Borrower that Lender (A) is capable of evaluating
investment risks independently, both in general and with regard to all transactions and investment strategies involving a security or securities; (B) will exercise independent judgment in evaluating the recommendations of any broker-dealer or
its associated persons, unless it has otherwise notified the broker-dealer in writing; and (C) has total assets of at least $50 million as of the date hereof. 
 (g) Borrower represents and warrants to Lender that it (and any successor entity) is, and at any time during which a Loan made pursuant to this Agreement is outstanding will be, a United States person
within the meaning of Section 7701(a)(30) of the U.S. Internal Revenue Code of 1986, as amended. 
 (h) Borrower represents
and warrants to Lender that any shares of Common Stock that Borrower transfers to Lender in respect of any Loan Termination, and any property or securities comprising any Non-Cash Distribution that Borrower transfers to Lender, in each case, shall
be made free from any lien, charge, claim or other encumbrance or restrictions (other than (x) a lien, charge, claim or other encumbrance or restriction routinely imposed on all securities by the relevant Clearance System and (y) any lien,
charge, claim or other encumbrance or restriction (i) in the case of any shares of Common Stock, that exists in respect to all outstanding shares of Common Stock and (ii) in the case of any property or securities comprising any Non-Cash
Distribution, that exists in respect of all such property or securities so distributed). 

 (i) The representations and warranties of Borrower and Lender under this Section 7
shall remain in full force and effect at all times during the term of this Agreement and shall survive the termination for any reason of this Agreement. 
 Section 8. Covenants.  
 (a) The parties hereto acknowledge that
Borrower has informed Lender that Borrower is a “financial participant” within the meaning of Section 101(22A) of the Bankruptcy Code. The parties hereto further acknowledge and agree that (i) each Loan hereunder is intended to
be a “securities contract,” as such term is defined in Section 741(7) of the Bankruptcy Code; (ii) each and every transfer of funds, securities and other property under this Agreement is intended to be a “transfer” and
a “settlement payment” or a “margin payment,” as such terms are used in Section 546(e) of the Bankruptcy Code; and (iii) Borrower is intended to be entitled to the protections afforded by, among other sections, Sections
362(b)(6), 546(e), 555 and 561 of the Bankruptcy Code. 
 (b) Lender shall, no later than five Business Days prior to any
repurchase of Common Stock, give Borrower a written notice of such repurchase (a “Repurchase Notice”) if, following such repurchase, the Outstanding Borrow Percentage as determined on such day after giving effect to such repurchase
would be greater than 8.0% or, after the first such Repurchase Notice, greater by 0.5% than the Outstanding Borrow Percentage included in the immediately preceding Repurchase Notice; provided that, in the event that the amount of Loaned
Shares provided pursuant to the initial Borrowing Notice causes the Outstanding Borrow Percentage to exceed 8.0%, then the first Repurchase Notice shall be deemed to have been given in connection with such initial Borrowing Notice. The
“Outstanding Borrow Percentage” as of any day is the fraction (A) the numerator of which is the aggregate number of Loaned Shares outstanding on such day and (B) the denominator of which is the number of shares of Common
Stock outstanding on such day, including such Loaned Shares. 
 (c) Borrower covenants and agrees with Lender that, insofar as
Borrower or any of its affiliates is the record owner of any Loaned Shares, Borrower shall use good faith efforts to use such Loaned Shares solely for the purpose of directly or indirectly facilitating the sale of the Convertible Notes and hedging
activities (including short sales of such Loaned Shares) relating to the Convertible Notes by the holders thereof. 

Section 9. Events of Default.  
 (a) All Loans, and any further obligation to make Loans under this Agreement, may, at the option of the non-defaulting party by a written notice to the defaulting party (which option shall be deemed
exercised, even if no notice is given, immediately on the occurrence of an event specified in Section 9(a)(v) or 9(a)(vi) below), be terminated (1) immediately on the occurrence of any of the events set forth in Section 9(a)(v) or
9(a)(vi) below or (2) two Business Days following such notice on the occurrence of any of the other events set forth below (each, a “Default”): 

(i) Borrower fails to deliver Loaned Shares to Lender as required by Section 4; 

(ii) Borrower fails to deliver or pay to Lender when due any cash, securities or other property as required by
Section 5; 
 (iii) Borrower fails to pay Lender a Loan Fee when due as required by Section 3;

 (iv) Borrower fails to pay Lender any amount when due as required by Section 10; 

(v) the filing by or on behalf of Lender or Borrower of a voluntary petition or an answer seeking reorganization,
arrangement, readjustment of its debts or for any other relief under any bankruptcy, reorganization, compromise, arrangement, insolvency, readjustment of debt, dissolution, moratorium, delinquency, winding-up or liquidation or similar act or law, of
any state, federal or other applicable foreign jurisdictions, now or hereafter existing (“Bankruptcy Law”), or any action by such party for, or consent or acquiescence to, the appointment of a receiver, trustee,

 
conservatory, custodian or similar official of such party, or of all or a substantial part of its property; or the making by such party of a general assignment for the benefit of creditors; or
the admission by such party in writing of its inability to pay its debts as they become due; 
 (vi) the filing
of any involuntary petition against Lender or Borrower in bankruptcy or seeking reorganization, arrangement, readjustment of its debts or for any other relief under any Bankruptcy Law and an order for relief by a court having jurisdiction in the
premises shall have been issued or entered therein; or any other similar relief shall be granted under any applicable federal or state law or law of any other applicable foreign jurisdictions; or a decree or order of a court having jurisdiction in
the premises for the appointment of a receiver, liquidator, sequestrator, trustee or other officer having similar powers over such party or over all or a part of its property shall have been entered; or the involuntary appointment of an interim
receiver, trustee or other custodian of such party or of all or a substantial part of its property or the issuance of a warrant of attachment, execution or similar process against any substantial part of the property of such party; and continuance
of any such event for 15 consecutive calendar days unless dismissed, bonded to the satisfaction of the court having jurisdiction in the premises or discharged; 
 (vii) Lender fails to provide any indemnity as required by Section 12; provided that Borrower may waive such Default by Lender in its sole discretion; 

(viii) Borrower notifies Lender of its inability to or intention not to perform Borrower’s obligations hereunder or
otherwise disaffirms, fails to perform, rejects or repudiates any of its obligations hereunder; or 
 (ix) any
representation made by Borrower under this Agreement in connection with any Loan or Loans hereunder shall be incorrect or untrue in any material respect when made or Borrower fails to comply in any material respect with any of its covenants under
this Agreement. 
 Section 10. Right to Extend; Lender’s Remedies. 

(a) Except to the extent a Loan is terminated pursuant to Section 4(c) as a result of a Default by Borrower, Borrower may, following
the termination of any Loan pursuant to Section 4, delay the date on which the related Loan Shares are due to Lender (the “Settlement Due Date”, as so delayed to the extent applicable), with respect to some or all (as the case
may be) of such Loaned Shares, if Borrower reasonably determines in good faith based on the advice of counsel that such extension with respect to some or all (as the case may be) of such Loan Shares is reasonably necessary to enable Borrower (or any
of its affiliates) to effect purchases of Common Stock related to the delivery of Loan Shares due to Lender in connection with this Agreement in a manner that would be in compliance with legal and regulatory requirements (i) applicable to
Borrower or such affiliates in purchasing such shares of Common Stock or (ii) if Borrower were deemed to be Lender or an affiliated purchaser of Lender, that would be applicable to Lender in purchasing such shares of Common Stock. 

(b) If, upon the termination of any Loan as a result of a Default by Borrower under Section 9 or pursuant to Section 4(c) on
any Settlement Due Date, the purchase of Common Stock in an amount equal to all or any portion of the Loaned Shares to be delivered to Lender by Borrower in accordance with Section 4(c) of this Agreement (i) shall be prohibited by any law,
rules or regulation of any governmental authority to which it is or would be subject, (ii) shall violate, or would upon such purchase reasonably likely violate, any order or prohibition of any court, tribunal or other governmental authority,
(iii) shall require the prior consent of any court, tribunal or governmental authority prior to any such repurchase, (iv) would subject Borrower, based on the advice of counsel to the Borrower, to any liability or potential liability under
any applicable federal securities laws (including, without limitation, Section 16 of the Exchange Act), or (v) shall be commercially impracticable in the time period required by Section 4(c), in the commercially reasonable judgment of
Borrower as a result of a demonstrable legal or regulatory impediment (including regulations of self-regulatory organizations) to such purchases (each of (i), (ii), (iii), (iv) and (v), a “Legal Obstacle”), then, in each case,
Borrower shall immediately notify Lender of the Legal Obstacle and the basis therefor, whereupon Borrower’s obligations under Section 4(c) shall be suspended until such time as no Legal Obstacle with respect to such obligations shall exist
(a “Repayment Suspension”). Following the 

 
occurrence of and during the continuation of any Repayment Suspension, Borrower shall use commercially reasonable efforts to remove or cure the Legal Obstacle as promptly as reasonably
practicable, including, in the case of clause (iii), Borrower using its commercially reasonable efforts to obtain the prior consent of the relevant court, tribunal or governmental authority in order to make any such repurchase; provided that
(except in circumstances where the Legal Obstacle resulted from the failure by Borrower to comply with applicable securities laws or regulations) Lender shall promptly reimburse all reasonable costs and expenses (including of legal counsel to
Borrower) incurred or, at Borrower’s election, provide reasonably adequate surety or guarantee for any such costs and expenses that may be incurred by Borrower, in each case, in removing or curing such Legal Obstacle; and provided further
that, if Borrower cannot remove or cure the Legal Obstacle within five Business Days, then Lender shall have the right at any time thereafter to notify Borrower of its election that Borrower pay to Lender, in lieu of the delivery of Loaned
Shares in accordance with Section 4(c), an amount in immediately available funds (the “Replacement Cash”) equal to the product of (A) the average Closing Price (the “Average Closing Price”) during the ten
consecutive Business Day period ending on the Business Day immediately preceding the date Borrower makes such payment, multiplied by (B) the number of Loaned Shares then outstanding. 

(c) If Borrower shall fail to pay the Replacement Cash to Lender in accordance with Section 10(b) above, then, in addition to any
other remedies available to Lender under this Agreement or under applicable law, Lender shall have the right (upon prior written notice to Borrower) to purchase a like number of Loaned Shares (“Replacement Shares”) in the principal
market for such securities in a commercially reasonable manner. To the extent Lender shall exercise such right, Borrower’s obligation to return a like number of Loaned Shares or to pay the Replacement Cash, as applicable, shall terminate, and
Borrower shall be liable to Lender for the purchase price of Replacement Shares (plus all other amounts, if any, due to Lender hereunder), all of which shall be due and payable within three Business Days of notice to Borrower by Lender of the
aggregate purchase price of the Replacement Shares. The purchase price of Replacement Shares purchased under this Section 10(c) shall include broker’s fees and commissions and all other reasonable costs, fees and expenses related to such
purchase. 
 Section 11. Transfers.  
 (a) All transfers of Loaned Shares to Borrower hereunder shall be made by the crediting by a Clearing Organization of such Loaned Shares to Borrower’s “securities account” (within the
meaning of Section 8-501 of the UCC) designated in the relevant Borrowing Notice maintained with such Clearing Organization. All transfers of Loaned Shares to Lender hereunder shall be made by the crediting of such Loaned Shares to
Lender’s Designated Account. In every transfer of “financial assets” (within the meaning of Section 8-102 of the UCC) hereunder, the transferor shall take all steps necessary (a) to effect a delivery to the transferee under
Section 8-301 of the UCC, or to cause the creation of a security entitlement in favor of the transferee under Section 8-501 of the UCC, (b) to enable the transferee to obtain “control” (within the meaning of
Section 8-106 of the UCC), and (c) to provide the transferee with comparable rights under any applicable foreign law or regulation that is applicable to such transfer. 

(b) All transfers of cash hereunder to Borrower or Lender shall be by wire transfer in immediately available, freely transferable funds.

 (c) A transfer of securities or cash may be effected under this Section 11 on any day except (i) a day on which the
transferee is closed for business at its address set forth in Section 16 or (ii) a day on which a Clearing Organization or wire transfer system is closed, if the facilities of such Clearing Organization or wire transfer system are required
to effect such transfer, in which case under clause (i) or (ii), such transfer shall be made on the immediately following day on which such exceptions are not in effect. 
 (d) To the extent permitted by law, neither this Agreement nor any interest or obligation in or under this Agreement may be transferred (whether by way of security or otherwise) by either party without
the prior written consent of the other party; provided that Borrower may, without the consent of Lender, transfer or assign all or any part of its rights or obligations under this Agreement to any of Borrower’s affiliates (i)(x) if such
a transfer is required by or under any law, rule, regulation or regulatory order or (y) if, absent such transfer, Borrower or any of its affiliates would incur a materially increased cost or other materially increased expense (compared to such
cost or expense as of the date hereof) or would experience 

 
any other material adverse effect, in either the case of (x) or (y), upon the advice to Borrower of counsel) and (ii) so long as, in the event Borrower is able to transfer to more than
one affiliate in compliance with all applicable laws, rules, regulations and regulatory orders and in a manner that would not result in Borrower or any of its affiliates incurring a materially increased cost or other materially increased expense
(compared to such cost or expense as of the date hereof) nor experiencing any other material adverse effect, such transfer is to the affiliate of Borrower that results in the least adverse effect to Lender (determined by Borrower in good faith and
in a commercially reasonable manner after consultation with Lender). Subject to the foregoing, this Agreement shall be binding upon and shall inure to the benefit of Borrower, Lender and their respective successors and permitted assigns. Any
purported transfer that is not in compliance with this Section 11(d) shall be null and void 
 Section 12.
Indemnities.  
 (a) Lender hereby agrees to indemnify and hold harmless Borrower and its affiliates and its former, present
and future directors, officers, employees from and against any and all liabilities, judgments, claims, settlements, losses, damages and other expenses (including, without limitation, direct losses relating to Borrower’s market activities as a
consequence of becoming subject to Section 16(b) under the Exchange Act, and including, without limitation, any forbearance from market activities or cessation of market activities and any losses in connection therewith or with respect to this
Agreement) (collectively, “Losses”) incurred or suffered by any such person or entity directly arising from (i) any breach by Lender of any of its representations or warranties contained in Section 7 or (ii) any
breach by Lender of any of its covenants or agreements in this Agreement; provided, however, that Lender shall not be liable for any Losses arising from (i) any breach by Borrower of any of its representations or warranties
contained in Section 7 or (ii) any breach by Borrower of any of its covenants or agreements in this Agreement. 
 (b)
In case any claim or litigation which might give rise to any obligation of Lender under this Section 12 (each an “Indemnifying Party”) shall come to the attention of the party seeking indemnification hereunder (the
“Indemnified Party”), the Indemnified Party shall within five Business Days notify the Indemnifying Party in writing of the existence and amount thereof; provided that the failure of the Indemnified Party to give such notice shall
not adversely affect the right of the Indemnified Party to indemnification under this Agreement, except to the extent the Indemnifying Party is materially prejudiced thereby. The Indemnifying Party shall promptly notify the Indemnified Party in
writing if it accepts such claim or litigation as being within its indemnification obligations under this Section 12. Such response shall be delivered no later than 45 days after the initial notification from the Indemnified Party;
provided that, if the Indemnifying Party reasonably cannot respond to such notice within 45 days, the Indemnifying Party shall respond to the Indemnified Party as soon thereafter as reasonably possible. 

(c) An Indemnifying Party shall be entitled to participate in and, if (i) in the good faith judgment of the Indemnified Party such
claim can properly be resolved by money damages alone and the Indemnifying Party has the financial resources to pay such damages and (ii) the Indemnifying Party admits that this indemnity fully covers the claim or litigation, the Indemnifying
Party shall be entitled to direct the defense of any claim at its expense, but such defense shall be conducted by legal counsel reasonably satisfactory to the Indemnified Party. An Indemnified Party shall not make any settlement of any claim or
litigation under this Section 12 without the written consent of the Indemnifying Party. Nothing in this clause (c) shall be deemed to limit, or be a waiver of either party in respect of, this Section 12. 

Section 13. Termination Of Agreement.  
 (a) This Agreement may be terminated (i) at any time by the written agreement of Lender and Borrower or (ii) by Lender or Borrower upon the occurrence of a Default by the other party.

 (b) Unless otherwise agreed by Borrower and Lender, the provisions of Section 12 shall survive the termination of this
Agreement. 

 Section 14. Registration Provisions. If, following the initial Loan hereunder
and registration of the initial Loaned Shares in respect of such Loan, any subsequent Loan and public sale of the Loaned Shares in respect of such subsequent Loan, based upon reasonable advice of counsel to Borrower, would require registration under
the Securities Act, Lender agrees to register such sale of shares of Common Stock as and to the extent provided in the Underwriting Agreement. 
 Section 15. Amendments. No amendment or modification in respect of this Agreement shall be effective unless it shall be in writing and signed by the parties hereto. 

Section 16. Notices.
