 (a) a “person” or “group” within the meaning of Section 13(d) of the
Exchange Act, other than the Company, its Wholly Owned Subsidiaries and the employee benefit plans of the Company and its Wholly Owned Subsidiaries, files a Schedule TO or any schedule, form or report under the Exchange Act disclosing that such
person or group has become the direct or indirect “beneficial owner,” as defined in Rule 13d-3 under the Exchange Act, of the Company’s Common Equity representing more than 50% of the voting
power of the Company’s Common Equity; 
 (b) the consummation of (1) any recapitalization, reclassification or
change of the Common Stock (other than changes resulting from a subdivision, combination or changes solely in par value) as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or
assets; (2) any share exchange, consolidation or merger of the Company pursuant to which the Common Stock will be converted into cash, securities or other property or assets; or (3) any sale, lease or other transfer in one transaction or a
series of transactions of all or substantially all of the consolidated assets of the Company and its Subsidiaries, taken as a whole, to any Person other than one of the Company’s Subsidiaries; provided, however, that a transaction
described in clause (1) or (2) in which the holders of all classes of the Company’s Common Equity immediately prior to such transaction own, directly or indirectly, more than 50% of all classes of Common Equity of the continuing or
surviving company or transferee or the parent thereof immediately after such transaction in substantially the same proportions (relative to each other) as such ownership immediately prior to such transaction shall not be a Fundamental Change
pursuant to this clause (b); 
 (c) the stockholders of the Company approve any plan or proposal for the liquidation or
dissolution of the Company; or 
 (d) the Common Stock (or other common stock, American depositary receipts, ordinary shares
or other common equity interests underlying the Notes) ceases to be listed or quoted on any of The New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or any of their respective successors); 

provided, however, that a transaction or transactions described in clause (a) or (b) above shall not constitute a Fundamental Change, if at
least 90% of the consideration received or to be received by the common stockholders of the Company, excluding cash payments for fractional shares and cash payments made pursuant to dissenters’ appraisal rights, in connection with such
transaction or transactions consists of shares of common stock, American depositary receipts, ordinary shares or other common equity interests, in each case, that are listed or quoted on any of The New York Stock Exchange, The NASDAQ Global Select
Market or The NASDAQ Global Market (or any of their 

  
 6 








 
respective successors) or will be so listed or quoted when issued or exchanged in connection with such transaction or transactions and as a result of such transaction or transactions such
consideration becomes Reference Property for the Notes in accordance with Section 14.07, excluding cash payments for fractional shares and cash payments made pursuant to dissenters’ appraisal rights (subject to the provisions of
Section 14.02(a)). For the avoidance of doubt, a Share Exchange Event pursuant to which (x) at least 90% of the consideration received or to be received by the common stockholders of the Company, excluding cash payments for fractional
shares and cash payments made pursuant to dissenters’ appraisal rights, consists of shares of common stock, American depositary receipts, ordinary shares or other common equity interests, in each case, that are listed or quoted on any of The
New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or any of their respective successors) or will be so listed or quoted when issued or exchanged in connection with such Share Exchange Event and (y) as a
result of which the Notes become convertible into such consideration, excluding cash payments for fractional shares and cash payments made pursuant to dissenters’ appraisal rights (subject to the provisions of Section 14.02(a)) shall not
constitute a Fundamental Change pursuant to clause (d) above. Any event, transaction or series of related transactions that constitute a Fundamental Change under both clause (a) and (b) above (determined without regard to the proviso in
clause (b) above) shall be deemed to be a Fundamental Change solely under clause (b) above. If any transaction in which the Common Stock is replaced by the securities of another entity occurs, following completion of any related Make-Whole
Fundamental Change Period (or, in the case of a transaction that would have been a Fundamental Change or a Make-Whole Fundamental Change but for the proviso immediately following clause (d) of this definition, following the effective
date of such transaction) references to the Company in this definition shall instead be references to such other entity. 

“Fundamental Change Company Notice” shall have the meaning specified in Section 15.02(c).

Note that is redeemed, repurchased or owned by any Affiliate of the Company (or any Person who was an Affiliate of the Company at any time during the three months preceding) may not be resold by such Affiliate (or such Person, as the case may be)
unless registered under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction that results in such Note or Common Stock, as the case may be, no longer being a “restricted
security” (as defined under Rule 144 under the Securities Act). The Company shall cause any Note that is redeemed, repurchased or owned by it to be surrendered to the Trustee for cancellation in accordance with Section 2.07. 

Section 2.07. Cancellation of Notes Paid, Converted, Etc. The Company shall cause all Notes surrendered for the purpose of
payment, redemption, repurchase (but excluding Notes repurchased pursuant to cash-settled swaps or other derivatives), including as described in Section 2.09, registration of transfer or exchange or conversion, if surrendered to any Person that
the Company controls other than the Trustee, to be surrendered to the Trustee for cancellation pursuant to Section 2.08 of the Base Indenture and such Notes shall no longer be considered “Outstanding” upon their payment, redemption,
repurchase, registration of transfer or exchange or conversion. All Notes delivered to the Trustee shall be canceled promptly by it, and, except for Notes surrendered for registration of transfer or exchange, no Notes shall be authenticated in
exchange for any Notes cancelled except as otherwise provided for in the Indenture. 
 Section 2.08. CUSIP Numbers. The Company
in issuing the Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in all notices issued to Holders as a convenience to such Holders; provided that any such notice
may state that no representation is made as to the correctness or accuracy of such numbers either as printed on the Notes or on such notice and that reliance may be placed only on the other identification numbers printed on the Notes. The
effectiveness of any such notice shall not be affected by any defect in, or omission of, such “CUSIP” numbers. The Company shall promptly notify the Trustee in writing of any change in the “CUSIP” numbers. 

Section 2.09. Additional Notes; Repurchases. The Company may, without the consent of, or notice to, the Holders and
notwithstanding Section 2.02, reopen the Indenture and issue additional Notes under the Indenture with the same terms as the Notes initially issued hereunder (other than differences in the issue date, issue price and interest accrued prior to
the issue date of such additional Notes) in an unlimited aggregate principal amount; provided that if any such additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal income


  
 18 








 
tax or securities laws purposes, such additional Notes shall have a separate CUSIP number. The Notes initially issued hereunder and any additional Notes under the Indenture shall rank equally and
ratably and shall be treated as a single series for all purposes under the Indenture.    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 Section 13.07 of the Base Indenture, as the Trustee shall reasonably request. In addition, the Company
may, to the extent permitted by law, and directly or indirectly (regardless of whether such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, whether by the Company or its Subsidiaries or through a private or
public tender or exchange offer or through counterparties to private agreements, including by cash-settled swaps or other derivatives, in each case without prior notice to the Holders and, upon receipt of a written order from the Company, the
Trustee shall cancel all Notes so surrendered.

(y) Notes for whose payment 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(c)) have been delivered to
the Trustee for cancellation; or (ii) after the Notes have (x) become due and payable, whether on the Maturity Date, any Redemption Date, any Fundamental Change Repurchase Date or otherwise and/or (y) been converted (and the related
consideration due upon conversion has been determined), the Company has deposited with the Trustee cash and/or has delivered to Holders shares of Common Stock, as applicable (in the case of Common Stock, solely to satisfy the Company’s
Conversion Obligation), sufficient to pay all of the Outstanding Notes and all other sums due and payable under the Indenture by the Company; and (b) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of

 ARTICLE 4 

PARTICULAR COVENANTS OF THE COMPANY 

Section 4.01. Payment of Principal and Interest. This Section 4.01 shall supersede Section 4.01 of the Base Indenture and all
references in the Base Indenture to Section 4.01 thereof shall be deemed, for the purposes of the Notes, to be references to this Section 4.01. The Company covenants and agrees that it will cause to be paid the principal (including the Fundamental
Change Repurchase Price and the Redemption Price, if applicable) of, and accrued and unpaid interest on, each of the Notes at the places, at the respective times and in the manner provided herein and in the Notes. 

Section 4.02. Paying Agent and Conversion Agent. The office or agency where the Notes may be surrendered for registration of
transfer or exchange or for presentation for payment, redemption or repurchase (“Paying Agent”) and Security Registrar for the Notes shall be located in the continental United States of America and shall initially be at the
Corporate Trust Office of the Trustee. The Company will also maintain an office or agency (“Conversion Agent”) in the continental United States of America where the Notes may be surrendered for conversion and where notices and
demands in respect of the Notes and the Indenture may be made. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such offices or agencies. If at any time the Company shall fail to maintain
any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made at the Corporate Trust Office or another office or agency of the Trustee. 

The Company may also from time to time designate as a Paying Agent 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
continental United States of America 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; provided that for the purposes of Article 15 of this Supplemental Indenture, the Paying Agent may be any agent,
depositary, tender agent, paying agent or other agent appointed by the Company to accomplish the purposes set forth therein. 
 The Company
hereby initially designates the Trustee as the Paying Agent, Security Registrar, Custodian and Conversion Agent and the Corporate Trust Office as the office or agency where Notes may be surrendered for registration of transfer or exchange or for
presentation for payment, redemption or repurchase (if applicable) or for conversion and where notices in respect of the Notes and the Indenture may be made; provided that the Trustee shall not be considered an agent of the Company for
service of process. 

  
 20 








 Section 4.03. Provisions as to Paying Agent. (a) Section 4.03(a)(3) of the
Base Indenture is hereby amended with respect to the Notes by replacing such Section 4.03(a)(3) in its entirety with the following: “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; and”. 
 Notwithstanding anything in the Base Indenture to the contrary, the
Company shall, on or before each due date of the principal (including the Fundamental Change Repurchase Price and the Redemption Price, if applicable) of, or accrued and unpaid interest on, the Notes, deposit with the Paying Agent a sum sufficient
to pay such principal (including the Fundamental Change Repurchase Price and the Redemption 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. 

(b) Notwithstanding anything in the Base Indenture to the contrary, if the Company shall act as its own Paying Agent, it will, on or before
each due date of the principal (including the Fundamental Change Repurchase Price and the Redemption Price, if applicable) of, and accrued and unpaid interest on, the Notes, set aside, segregate and hold in trust for the benefit of the Holders of
the Notes a sum sufficient to pay such principal (including the Fundamental Change Repurchase Price and the Redemption Price, if applicable) and accrued and unpaid interest so becoming due and will promptly notify the Trustee in writing of any
failure to take such action and of any failure by the Company to make any payment of the principal (including the Fundamental Change Repurchase Price and the Redemption Price, if applicable) of, or accrued and unpaid interest on, the Notes when the
same shall become due and payable. 
 (c) Notwithstanding anything in the Base Indenture to the contrary and subject to any unclaimed
property laws, any money and shares of Common Stock deposited with the Trustee, Conversion Agent or any Paying Agent, or then held by the Company, in trust for the payment of the principal (including the Fundamental Change Repurchase Price and the
Redemption Price, if applicable) of, accrued and unpaid interest on and the consideration due upon conversion of any Note and remaining unclaimed for two years after such principal (including the Fundamental Change Repurchase Price and the
Redemption Price, if applicable), interest or consideration due upon conversion has become due and payable shall 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, Conversion Agent 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. 
 Section 4.04.
Existence. Subject to Article 11, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence.

reports (or portions thereof) that are subject to confidential treatment and any correspondence with the 

  
 21 








 
Commission) (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 thereto) shall be deemed to be delivered to and filed with the Trustee for purposes of this Section 4.05(a) at the time such documents are filed via the EDGAR system (or any
successor thereto), it being understood that the Trustee shall have no responsibility to determine if such deliveries or filings have been made. Section 5.03(a) of the Base Indenture shall, with respect to the Notes, be superseded in its
entirety by this Section 4.05(a), and any reference in the Base Indenture to such Section 5.03(a) shall, with respect to the Notes, be deemed to refer instead to this Section 4.05(a). 

(b) Delivery of the reports and documents described in subsection (a) above to the Trustee is for informational purposes only, and the
Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which
the Trustee is entitled to conclusively rely on an Officer’s Certificate). 
 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. 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, 2017) an Officer’s Certificate stating whether the signer thereof has 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. 
 In
addition, the Company shall deliver to the Trustee, as soon as possible, and in any event within 30 days after an Executive Officer of 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 proposing to take in respect thereof; provided that the Company shall not be required to deliver such an Officer’s
Certificate if such Event of Default or Default has been cured. 
 Section 13.12 of the Base Indenture shall, with respect to the
Notes, be superseded in its entirety by this Section 4.07, and any reference in the Base Indenture to such Section 13.12 shall, with respect to the Notes, be deemed to refer instead to this Section 4.07. 

  
 22 








 Section 4.08. Further Instruments and Acts. Upon request of the Trustee, the Company
will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of the Indenture. 

Section 4.09. Additional Amounts. 

(a) If the Company consolidates with or merges with or into, or sells, conveys, transfers or leases all or substantially all of the
Company’s properties and assets to, another company pursuant to Section 11.02, and the Successor Company is not organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, then all
payments and deliveries made by, or on behalf of, the Successor Company under or with respect to the Notes, including, but not limited to, payments of principal (including, if applicable, the Fundamental Change Repurchase Price and the Redemption
Price), payments of interest and deliveries of Common Stock or other Reference Property and/or payments of cash, in each case, upon conversion, shall be made without withholding or deduction for, or on account of, any present or future taxes,

made or deemed made (or any political subdivision or taxing authority thereof or therein) (each, as applicable, a “Relevant Taxing Jurisdiction”), unless such withholding or deduction is required by law or by regulation or
governmental policy having the force of law. In the event that any such withholding or deduction is so required, the Successor Company shall pay such additional amounts (the “Additional Amounts”) as may be necessary to ensure that
the net amount received by the beneficial owner after such withholding or deduction (and after deducting or withholding any taxes on the Additional Amounts) shall equal the amounts that would have been received by such beneficial owner had no such
withholding or deduction been required; provided that no Additional Amounts shall be payable: 
 (i) for or on account of: 

(A) any tax, duty, assessment or other governmental charge that would not have been imposed but for: 

(1) the existence of any present or former connection between the Holder or beneficial owner of such Note and the Relevant
Taxing Jurisdiction, other than merely holding such Note or the receipt of payments thereunder, including, without limitation, such Holder or beneficial owner being or having been a national, domiciliary or resident of such Relevant Taxing
Jurisdiction or treated as a resident thereof or being or having been physically present or engaged in a trade or business therein or having or having had a permanent establishment therein; 

(2) the presentation of such Note (in cases in which presentation is required) more than 30 days after the later of the date

each case, upon conversion of such Note became due and payable pursuant to the terms thereof or was made or duly provided for; or 

  
 23 








 (3) the failure of the Holder or beneficial owner to comply with a timely
request from the Successor Company to provide certification, information, documents or other evidence concerning such Holder’s or beneficial owner’s nationality, residence, identity or connection with the Relevant Taxing Jurisdiction, or
to make any declaration or satisfy any other reporting requirement relating to such matters, if and to the extent that due and timely compliance with such request is required by statute, regulation or administrative practice of the Relevant Taxing
Jurisdiction in order to reduce or eliminate any withholding or deduction as to which Additional Amounts would have otherwise been payable to such Holder or beneficial owner; 

(B) any estate, inheritance, gift, sale, transfer, excise, personal property or similar tax, assessment or other governmental
charge; 
 (C) any tax, duty, assessment or other governmental charge that is payable otherwise than by withholding or
deduction from payments under or with respect to the Notes; 
 (D) any tax, assessment, withholding or deduction required by
sections 1471 through 1474 of the United States Internal Revenue Code of 1986, as amended (“FATCA”), any current or future Treasury Regulations or rulings promulgated thereunder, any law, regulation or other official guidance
enacted in any jurisdiction implementing FATCA, any intergovernmental agreement between the United States and any other jurisdiction to implement FATCA or any law enacted by such other jurisdiction to give effect to such agreement, or any agreement
with the U.S. Internal Revenue Service under FATCA; 
 (E) any tax, duty, assessment or other governmental charge required to
be withheld or deducted by any Paying Agent from any payment of principal of, or interest on, any Notes, if such payment could have been made without such withholding or deduction by at least one other Paying Agent; or 

(F) any combination of taxes referred to in the preceding clauses (A), (B), (C), (D) and (E), or 

(ii) with respect to any payment of the principal of (including the Fundamental Change Repurchase Price and the Redemption
Price, if applicable) and interest on, such Note or the delivery of Common Stock or other Reference Property and/or payments of cash, in each case, upon conversion of such Note to a Holder, if the Holder is a fiduciary, partnership or person other
than the sole beneficial owner of that payment to the extent that such payment would be required to be included in the income under the laws of the Relevant Taxing Jurisdiction, for tax purposes, of a beneficiary or settlor with respect to the
fiduciary, a partner or member of that partnership or a beneficial owner who would not have been entitled to such Additional Amounts had that beneficiary, settlor, partner, member or beneficial owner been the Holder thereof. 

  
 24 








 (b) In the event that (i) the taxing authority of a Relevant Taxing Jurisdiction determines
that amounts should have been withheld or deducted in respect of any payments or deliveries under or with respect to the Notes in excess of any amounts that were actually withheld or deducted by the Successor Company, and (ii) the Successor
Company would have been required to pay Additional Amounts if such amounts had been withheld or deducted, then the Successor Company shall indemnify each beneficial owner of the Notes, on an after-tax basis,
for any and all losses incurred as a result of its failure to make such withholdings and deductions and to pay Additional Amounts; provided that (i) only direct losses (and no consequential losses or damages) shall be recoverable
pursuant to this Section 4.09(b), (ii) no indemnification shall be required pursuant to this Section 4.09(b) unless and after such beneficial owner has exhausted all reasonable remedies available to it to reduce or eliminate the amount of
such losses, and (iii) as a condition of such indemnification such beneficial owner shall reasonably assist the Successor Company in any attempt the Successor Company may make to seek to secure a reduction or refund of any such amounts, which
reduction or refund shall be for the account of the Successor Company to the extent of any indemnification previously provided to such beneficial owner. 

(c) If the Successor Company is required to make any deduction or withholding from any payments with respect to the Notes, the Successor
Company will deliver to the Trustee official tax receipts evidencing the remittance to the relevant tax authorities of the amounts so withheld or deducted or other evidence reasonably satisfactory to the Trustee.

payments of cash, in each case, upon conversion of any Note or the payment of principal of (including the Fundamental Change Repurchase Price and the Redemption Price, if applicable) and interest on, any Note or any other amount payable with respect
to such Note, shall be deemed to include payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to this Section 4.09.

(whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or
governmental body), then, and in each and every such case (other than an Event of Default specified in Section 6.02(i) or Section 6.02(j) with respect to the Company), unless the principal of all of the Notes shall have already become due
and payable, either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then Outstanding determined in accordance with Section 8.04 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 contained in the Indenture or in the Notes to the contrary notwithstanding. If an Event of Default specified in Section 6.02(i) or Section 6.02(j) with respect to the Company occurs 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.

unpaid interest on, 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 and on such principal at the rate borne by the Notes at such time, to the extent that payment of such interest is enforceable under applicable law) and amounts due to the Trustee pursuant to Section 7.06 of the Base Indenture,
and if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) any and all existing Events of Default under the Indenture, other than the nonpayment of the principal of and accrued and
unpaid interest, if any, on Notes that shall have become due solely by such acceleration, shall have been cured or waived pursuant to Section 6.10., then and in every such case (except as provided in the immediately succeeding sentence) the
Holders of a majority in 

  
 27 








 aggregate principal amount of the Notes then Outstanding, by written notice to the Company and to the Trustee,
may waive all Defaults or Events of Default with respect to the Notes and rescind and annul such declaration and its consequences and such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured
for every purpose of the Indenture; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon. Notwithstanding anything to the contrary
herein, no such waiver or rescission and annulment shall extend to or shall affect any Default or Event of Default resulting from (i) the nonpayment of the principal (including the Fundamental Change Repurchase Price and the Redemption Price,
if applicable) of, or accrued and unpaid interest on, any Notes, (ii) a failure to redeem or 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.

to file with the Commission pursuant to Section 13 or Section 15(d) of the Exchange Act or (ii) the Company’s failure to comply with its obligations as set forth in Section 4.05 (the obligations described in clauses
(i) and (ii), the “Reporting Obligations”) shall (x) for the first 180 days after the occurrence of such an Event of Default (beginning on, and including, the date on which such an Event of Default first occurs), consist
exclusively of the right to receive additional interest (“Additional Interest”) on the Notes at a rate equal to 0.25% per annum of the principal amount of the Notes Outstanding for each day during such
180-day period on which such Event of Default is continuing and (y) for the period from, and including, the 181st day after the occurrence of such an Event of Default to, and including, the 360th day
after the occurrence of such an Event of Default, consist exclusively of the right to receive Additional Interest on the Notes at a rate equal to 0.50% per annum of the principal amount of the Notes Outstanding for each day during such additional 180-day period on which such Event of Default is continuing. In no event shall the Additional Interest described in this Section 6.04 accrue at a rate in excess of 0.25% per annum during the initial 180-day period or 0.50% per annum during the subsequent 180-day period, regardless of the number of events or circumstances giving rise to the requirement to pay such
Additional Interest. 
 If the Company so elects to pay Additional Interest, any such Additional Interest shall be payable in the same
manner and on the same dates as the stated interest payable on the Notes. On the 361st day after such Event of Default (if the Event of Default relating to the Company’s failure to comply with the Reporting Obligations is not cured or waived
prior to such 361st day), the Notes shall be immediately subject to acceleration as provided in Section 6.03. In the event the Company does not elect to pay Additional Interest following an Event of Default relating to the Reporting Obligations
in accordance with this Section 6.04 or the Company elected to make such payment but does not pay the Additional Interest when due, the Notes shall be immediately subject to acceleration as provided in Section 6.03. 

In order to elect to pay Additional Interest as the sole remedy during the first 360 days after the occurrence of any Event of Default
relating to the failure by the Company to comply with the Reporting Obligations, in accordance with this Section 6.04, the Company must notify all Holders of the Notes, the Trustee and the Paying Agent in writing of such election on or before
the close of 

  
 28 








 business on the date on which such Event of Default first occurs. Upon the failure to timely give such notice,
the Notes shall be immediately subject to acceleration as provided in Section 6.03. The Trustee shall not at any time be under any duty or responsibility to any Holder of Notes to determine the Additional Interest, or with respect to the
nature, extent, or calculation of the amount of Additional Interest owed, or with respect to the method employed in such calculation of the Additional Interest. 

Section 6.05. Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause (a) or (b) of
Section 6.02 shall have occurred, the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of the Notes, the whole 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 at such time (to the extent that payment of such interest on any overdue principal and interest, if any, is enforceable under applicable law), and, in addition
thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under Section 7.06 of the Base Indenture. If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as
trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the
Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the Notes, wherever situated. 

In the event there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the Notes
under Title 11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the
Company or such other obligor, the property of the Company or such other obligor, or in the event of any other judicial proceedings relative to the Company or such other obligor upon the Notes, or to the creditors or property of the Company or such
other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the
provisions of this Section 6.05, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal and accrued and unpaid interest, if any, in respect of the
Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may deem necessary or advisable in order to have the claims of the Trustee (including any claim for the
reasonable compensation, expenses and disbursements 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 7.06 of the Base Indenture; and any
receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Holders to make such payments to the Trustee, as administrative expenses, and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for reasonable compensation, expenses 

  
 29 








 and disbursements, including agents and counsel fees, and including any other amounts due to the Trustee under
Section 7.06 of the Base Indenture, incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses 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. 
 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 and disbursements of the Trustee, its agents and counsel permitted under Section 7.06 of the
Base Indenture, be for the ratable benefit of the Holders of the Notes. 
 In any proceedings brought by the Trustee (and in any proceedings
involving the interpretation of any provision of the Indenture to which the Trustee shall be a party) the Trustee shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any Holders of the Notes parties to any
such proceedings. 
 In case the Trustee shall have proceeded to enforce any right under the Indenture and such proceedings shall have been
discontinued or abandoned because of any waiver pursuant to Section 6.10 or any rescission and annulment pursuant to Section 6.03 or for any other reason or shall have been determined adversely to the Trustee, then and in every such case
the Company, the Holders and the Trustee shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Holders and the
Trustee shall continue as though no such proceeding had been instituted. 
 Section 6.06. Application of Monies Collected by
Trustee. Any monies collected by the Trustee pursuant to this Article 6 with respect to the Notes shall be applied in the following order, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the
several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid: 
 First, to the
payment of all amounts due the Trustee and its agents and counsel under Section 7.06 of the Base Indenture; 
 Second, in case
the principal of the Outstanding Notes shall not have become due and be unpaid, to the payment of interest on, and any cash due upon conversion of, the Notes in default in the order of the date due of the payments of such interest and cash due upon
conversion, as the case may be, with interest (to the extent that such interest has been collected by the Trustee) upon such overdue payments at the rate borne by the Notes at such time, such payments to be made ratably to the Persons entitled
thereto; 

  
 30 








 Third, in case the principal of the Outstanding Notes shall have become due, by
declaration or otherwise, and be unpaid to the payment of the whole amount (including, if applicable, the payment of the Fundamental Change Repurchase Price, the Redemption Price and any cash due upon conversion) then owing and unpaid upon the Notes
for principal and interest, if any, with interest on the overdue principal and, to the extent that such interest has been collected by the Trustee, upon overdue installments of interest at the rate borne by the Notes at such time, and in case such
monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment of such principal (including, if applicable, the Fundamental Change Repurchase Price, the Redemption Price and the cash due upon
conversion) and interest without preference or priority of principal over interest, or of interest over principal or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate
of such principal (including, if applicable, the Fundamental Change Repurchase Price, the Redemption Price and any cash due upon conversion) and accrued and unpaid interest; and 

Fourth, to the payment of the remainder, if any, to the Company. 

Section 6.07. Proceedings by Holders. Except to enforce the right to receive payment of principal (including, if applicable, the
Fundamental Change Repurchase Price and the Redemption 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 satisfactory to it in its reasonable judgment against any loss, claim, liability or expense to be incurred therein or thereby; 

(d) the Trustee for 60 days after its receipt of such notice, request and offer of such security or indemnity, shall have neglected or refused
to institute any such action, suit or proceeding; and 
 (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 6.10, 

  
 31 








 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 6.07, each and every Holder and the Trustee shall be entitled to such relief as can be given either at law or in equity. 

Solely for purposes of the Notes, whenever Section 7.02(d) or Section 7.02(f) of the Base Indenture makes reference to the Trustee
having the right to receive security or indemnity reasonably satisfactory to it against costs, expenses and liabilities, such reference shall be replaced by a reference to the Trustee having the right to receive security or indemnity satisfactory to
it in its reasonable judgment against losses, liabilities, claims or expenses. 
 Notwithstanding any other provision of the Indenture and
any provision of any Note, each Holder of the Notes shall have the right to receive payment or delivery, as the case may be, of (x) the principal (including the Fundamental Change Repurchase Price and the Redemption 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 on or after the applicable due date, as the case may be. 
 Section 6.08. Proceedings by
Trustee. In case of an Event of Default, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by the Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such
rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in the Indenture or in aid of the exercise of any power granted in the
Indenture, or to enforce any other legal or equitable right vested in the Trustee by the Indenture or by law. 
 Section 6.09.
Remedies Cumulative and Continuing. Except as provided in the last paragraph of Section 2.07 of the Base Indenture, all powers and remedies given by this Article 6 to the Trustee or to the Holders shall, to the extent permitted by law,
be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the Holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and
agreements contained in the Indenture, and no delay or omission of the Trustee or of any Holder of any of the Notes to exercise any right or power accruing upon any Default or Event of Default shall impair any such right or power, or shall be
construed to be a waiver of any such Default or Event of Default or any acquiescence therein; and, subject to the provisions of Section 6.07, every power and remedy given by this Article 6 or by law to the Trustee or to the Holders may be
exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders. 
 Section 6.10. Direction
of Proceedings and Waiver of Defaults by Majority of Holders. The Holders of a majority of the aggregate principal amount of the Notes at the time Outstanding determined in accordance with Section 8.04 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 the Notes; provided, however, 

  
 32 








 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 in good faith, and subject to its duties under the Trust
Indenture Act, is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability. The Holders of a majority in aggregate principal amount of the Notes at the time Outstanding determined in accordance
with Section 8.04 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 the Fundamental Change Repurchase Price and the Redemption Price, if applicable) of, the Notes when due that has not been cured pursuant to the provisions of Section 6.02, (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 10 cannot be modified or amended without the consent of each Holder of an
Outstanding Note affected. Upon any such waiver the Company, the Trustee and the Holders of the Notes shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other Default or Event of
Default or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 6.10, said Default or Event of Default shall for all purposes of the Notes and the Indenture
be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. 

Section 6.11. Notice of Defaults. The Trustee shall, within 90 days after obtaining actual knowledge of a Default of which a
Responsible Officer has actual knowledge, send to all Holders as the names and addresses of such Holders appear upon the Security Register, notice of all Defaults known to such 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 of (including the Fundamental Change Repurchase Price and the Redemption Price, if applicable), or accrued and unpaid interest
on, any of the Notes or a Default in the payment or delivery of the consideration due upon conversion, the Trustee shall be protected in withholding such notice if and so long as the Trustee in good faith determines that the withholding of such
notice is in the interests of the Holders. This Section 6.11 shall supersede Section 7.14 of the Base Indenture, and any reference in the Base Indenture to such Section 7.14 thereof shall be deemed to refer instead to this
Section 6.11. The proviso set forth in Section 315(b) of the Trust Indenture Act shall not apply with respect to the Notes. 

Section 6.12. Undertaking to Pay Costs. All parties to the Indenture agree, and each Holder of any Note by its acceptance thereof
shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under the Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the
filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such
suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section 6.12 (to the extent permitted by law) shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Notes at the time Outstanding determined in accordance with Section 8.04 of the Base Indenture, or 

  
 33 








 to any suit instituted by any Holder for the enforcement of the payment of the principal of or accrued and unpaid
interest, if any, on any Note (including, but not limited to, the Fundamental Change Repurchase Price and the Redemption Price, if applicable) 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 14.

Section 9.02. Call of Meetings by Trustee. The Trustee may at any time call a meeting of Holders to take any action specified in
Section 9.01, to be held at such time and at such place as the Trustee shall determine. Notice of every meeting of the Holders, setting forth the time and the place of such meeting and in general terms the action proposed to be taken at such
meeting and the establishment of any record date pursuant to Section 8.01 of the Base Indenture, shall be mailed to Holders of such Notes at their addresses as they shall appear on the Security Register. Such notice shall also be mailed to the
Company. Such notices shall be mailed not less than 20 nor more than 90 days prior to the date fixed for the meeting. 
 Any meeting of
Holders shall be valid without notice if the Holders of all Notes then Outstanding are present in person or by proxy or if notice is waived before or after the meeting by the Holders of all Notes then Outstanding, and if the Company and the Trustee
are either present by duly authorized representatives or have, before or after the meeting, waived notice. 

  
 34 








 Section 9.03. Call of Meetings by Company or Holders. In case at any time the
Company, pursuant to a Board Resolution, or the Holders of at least 10% of the aggregate principal amount of the Notes then Outstanding, shall have requested the Trustee to call a meeting of Holders, by written request setting forth in reasonable
detail the action proposed to be taken at the meeting, and the Trustee shall not have mailed the notice of such meeting within 20 days after receipt of such request, then the Company or such Holders may determine the time and the place for such
meeting and may call such meeting to take any action authorized in Section 9.01, by mailing notice thereof as provided in Section 9.02. 

Section 9.04. Qualifications for Voting. To be entitled to vote at any meeting of Holders a Person shall (a) be a Holder of
one or more Notes on the record date pertaining to such meeting or (b) be a Person appointed by an instrument in writing as proxy by a Holder of one or more Notes on the record date pertaining to such meeting. The only Persons who shall be
entitled to be present or to speak at any meeting of Holders shall be the Persons entitled to vote at such meeting and their counsel and any representatives of the Trustee and its counsel and any representatives of the Company and its counsel. 

Section 9.05. Regulations. Notwithstanding any other provisions of the Indenture, the Trustee may make such reasonable regulations
as it may deem advisable for any meeting of Holders, in regard to proof of the holding of Notes and of the appointment of proxies, and in regard to the appointment and duties of inspectors of votes, the submission and examination of proxies,
certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall think fit. 

The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders as provided in Section 9.03, in which case the Company or the Holders calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the
meeting shall be elected by vote of the Holders of a majority in aggregate principal amount of the Notes represented at the meeting and entitled to vote at the meeting. 

Subject to the provisions of Section 8.04 of the Base Indenture, at any meeting of Holders each Holder or proxyholder shall be entitled
to one vote for each $1,000 principal amount of Notes held or represented by him or her; provided, however, that no vote shall be cast or counted at any meeting in respect of any Note challenged as not Outstanding and ruled by the
chairman of the meeting to be not Outstanding. The chairman of the meeting shall have no right to vote other than by virtue of Notes held by it or instruments in writing as aforesaid duly designating it as the proxy to vote on behalf of other
Holders. At any meeting of Holders, the presence of Persons holding or representing Notes in an aggregate principal amount sufficient to take action on the business for the transaction of which such meeting was called shall constitute a quorum. Any
meeting of Holders duly called pursuant to the provisions of Section 9.02 or Section 9.03 may be adjourned from time to time by the Holders of a majority of the aggregate principal amount of Notes represented at the meeting, whether or not
constituting a quorum, and the meeting may be held as so adjourned without further notice.

meeting shall appoint two inspectors of votes who shall count all votes cast at the meeting for or against any resolution and who shall make and file with the secretary of the meeting their verified written reports in duplicate of all votes cast at
the meeting. A record in duplicate of the proceedings of each meeting of Holders shall be prepared by the secretary of the meeting and there shall be attached to said record the original reports of the inspectors of votes on any vote by ballot taken
thereat and affidavits by one or more Persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that said notice was mailed as provided in Section 9.02. The record shall show the aggregate principal
amount of the Notes voting in favor of or against any resolution. The record shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one of the duplicates shall be delivered to the Company and the
other to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. 
 Any record so
signed and verified shall be conclusive evidence of the matters therein stated. 
 Section 9.07. No Delay of Rights by Meeting.
Nothing contained in this Article 9 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

SUPPLEMENTAL INDENTURES 

Section 10.01. Applicability of Article 9 of the Base Indenture. Article 9 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 their entirety Article 9 of the Base Indenture, and all references in the Base Indenture to Article 9 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 or the applicable provisions set forth in this Article 10, respectively. 

Section 10.02. Supplemental Indentures Without Consent of Holders. The Company, when authorized by the resolutions
of the Board of Directors 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 one or more of the following purposes:

 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 10.02 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 10.03. 

Section 10.03. Supplemental Indentures with Consent of Holders. With the consent (evidenced as provided in Article 8 of the Base
Indenture) of the Holders of at least a majority of the aggregate principal amount of the Notes then Outstanding (determined in accordance with Article 8 of the Base Indenture and including, without limitation, consents obtained in connection with a
repurchase of, or tender or exchange offer for, Notes), the Company, when authorized by the resolutions of the Board of Directors and the Trustee, at the Company’s expense, may from time to 

  
 37 








 
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 affected, no such supplemental indenture shall: 

(a) reduce the amount of Notes whose Holders must consent to an amendment; 

(b) reduce the rate, or extend the stated time for payment, of interest on any Note;

(i) make any change in this Article 10 that requires each Holder’s consent or in the waiver provisions in Section 6.03 or
Section 6.10. 
 Upon the written request of the Company, and upon the filing with the Trustee of evidence of the consent of Holders as
aforesaid and subject to Section 10.06, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under 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 this Section 10.03 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. 
 Until an
amendment, supplement or waiver becomes effective, any consent to it by a Holder is a continuing consent by such Holder and every subsequent Holder of such consenting Holder’s Note, or portion of such consenting Holder’s Note, that
evidences the same debt as such consenting 

  
 38 








 
Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder or subsequent Holder may revoke the consent as to its Note if the Trustee receives written
notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder. 

Section 10.04. Effect of Supplemental Indentures. Upon the execution of any supplemental indenture pursuant to the provisions of
this Article 10, the Indenture shall be and be deemed to be modified and amended, with respect to the Notes only, in accordance therewith and the respective rights, limitation of rights, obligations, duties and immunities under the Indenture of the
Trustee, the Company and the Holders shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments and all the terms and 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 with respect to the Notes. 
 Section 10.05.
Notation on Notes. Notes authenticated and delivered after the execution of any supplemental indenture pursuant to the provisions of this Article 10 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 the Trustee shall so determine, new Notes so modified as to conform, in the opinion of the Board of Directors, to any modification of the Indenture contained in any such
supplemental indenture may, at the Company’s expense, be prepared and executed by the Company, authenticated by the Trustee (or an Authenticating Agent duly appointed by the Trustee pursuant to Section 2.10 of the Base Indenture) upon
receipt of a Company Order and delivered in exchange for the Notes then Outstanding, upon surrender of such Notes then Outstanding. 

Section 10.06. Evidence of Compliance of Supplemental Indenture to Be Furnished to Trustee. In addition to the documents required
by Section 13.07 of the Base Indenture, the Trustee shall receive an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture executed pursuant hereto complies with the requirements of this
Article 10, is permitted or authorized by the Indenture and, with respect to the Opinion of Counsel, that the supplemental indenture is the legal, valid and binding obligation of the Company, enforceable against it in accordance with its terms. 

ARTICLE 11 

CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE 

Section 11.01. Applicability of Article 10 and Section 4.05 of the Base Indenture. 

(a) Article 10 of the Base Indenture shall not apply to the Notes. Instead the provisions set forth in this Article 11 shall, with respect to
the Notes, supersede in their entirety Article 10 of the Base Indenture, and all references in the Base Indenture to Article 10 thereof and the provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to
this Article 11 or the applicable provisions set forth in this Article 11, respectively. 
 (b) Section 4.05 of the Base Indenture and
any reference in the Base Indenture to any such Section or the provisions contained therein shall be deemed deleted with respect to the Notes. 

  
 39 








 Section 11.02. Company May Consolidate, Etc. on Certain Terms. Subject to the
provisions of Section 11.03, the Company shall not consolidate with, merge with or into, or sell, convey, transfer or lease all or substantially all of the consolidated assets of the Company and its Subsidiaries, taken as a whole, to another Person,
unless: 
 (a) the resulting, surviving or transferee Person (the “Successor Company”), if not the Company, shall be
(1) a corporation organized and existing under the laws of the United States of America, any State thereof or the District of Columbia or (2) a corporation or entity treated as a corporation for U.S. federal income tax purposes organized
and existing under the laws of the Islands of Bermuda, the Netherlands, Belgium, Switzerland, Luxembourg, the Republic of Ireland, Canada or the United Kingdom, 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 (including, for the avoidance of doubt, the obligation to pay Additional Amounts, as set forth in Section 4.09); 

(b) if the Company is not the resulting, surviving or transferee Person, the Successor Company shall have delivered to the Trustee an
Officer’s Certificate and an Opinion of Counsel, each stating that such consolidation, merger, sale, conveyance, transfer or lease and such supplemental indenture, if any, is authorized or permitted by, and complies with, the Indenture; and

 (c) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing under the
Indenture. 
 For purposes of this Section 11.02, the sale, conveyance, transfer or lease of all or substantially all of 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 consolidated assets of the Company and its Subsidiaries, taken as a whole, to another Person. 

Section 11.03. Successor Company 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, except in the case of a lease of all or substantially all of the consolidated assets of the Company and its Subsidiaries, taken as a whole, shall be substituted for the
Company, with the same effect as if it had been named herein as the party of the first part. Such Successor Company thereupon may cause to be signed, and may issue either in its own name or in the name of the Company any or all of the Notes issuable
hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon a Company Order of such Successor Company instead of the Company and subject to all the terms, conditions and limitations in the Indenture
prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that previously shall have been signed and delivered by the Officers of the Company to the Trustee for authentication, and any Notes
that such Successor 

  
 40 








 
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 11 the Person named as the “Company” in the first paragraph of this Supplemental Indenture (or any successor that shall thereafter have become such in the manner
prescribed in this Article 11) 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 11.04. Opinion of
Counsel to Be Given to Trustee. No such 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 11. 

ARTICLE 12 
 NO
RECOURSE 
 Section 12.01. No Recourse. 

No recourse under or upon any obligation, covenant or agreement of this Supplemental Indenture, or of the Notes, or for any claim based
thereon or otherwise in respect thereof, shall be had against any incorporator, stockholder, officer or director, past, present or future as such, of the Company, of any predecessor or Successor Company or of any issuer of any securities underlying
the Notes, either directly or through the Company, any such predecessor or Successor Company or any such issuer, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being
expressly understood that this Supplemental Indenture and the obligations issued hereunder are solely corporate obligations, and that no such personal liability whatever shall attach to, or is or shall be incurred by, the incorporators,
stockholders, officers or directors as such, of the Company, of any such predecessor or Successor Company or any such issuer, or any of them, because of the creation of the indebtedness hereby authorized, or under or by reason of the obligations,
covenants or agreements contained in this Supplemental Indenture or in the Notes or implied therefrom; and that any and all such personal liability of every name and nature, either at common law or in equity or by constitution or statute, of, and
any and all such rights and claims against, every such incorporator, stockholder, officer or director as such, because of the creation of the indebtedness hereby authorized, or under or by reason of the obligations, covenants or agreements contained
in this Supplemental Indenture or in the Notes or implied therefrom, are hereby expressly waived and released as a condition of, and as a consideration for, the execution of this Supplemental Indenture and the issuance of the Notes.

 ARTICLE 13 

[INTENTIONALLY OMITTED] 

ARTICLE 14 

CONVERSION OF NOTES 

Section 14.01. Conversion Privilege. (a) Subject to and upon compliance with the provisions of this Article 14, each Holder of a
Note shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple thereof) of such Note (i) subject to satisfaction of the conditions described
in Section 14.01(b), at any time prior to the close of business on the Business Day immediately preceding June 1, 2024 under the circumstances and during the periods set forth in Section 14.01(b), and (ii) regardless of the conditions described in
Section 14.01(b), on or after June 1, 2024 and prior to the close of business on the Business Day immediately preceding the Maturity Date, in each case, at an initial conversion rate of 20.4891 shares of Common Stock (subject to adjustment as
provided in this Article 14, the “Conversion Rate”) per $1,000 principal amount of Notes (subject to, and in accordance with, the settlement provisions of Section 14.02, the “Conversion Obligation”). 

(b) (i) Prior to the close of business on the Business Day immediately preceding June 1, 2024, a Holder may surrender all or any
portion of its Notes for conversion at any time during the five Business Day period immediately after any five consecutive Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of
Notes, as determined following a request by a Holder of Notes in accordance with this subsection (b)(i), for each Trading Day of the Measurement Period was less than 98% of the product of the Last Reported Sale Price of the Common Stock and the
Conversion Rate on each such Trading Day. The Trading Prices shall be determined by the Bid Solicitation Agent pursuant to this subsection (b)(i) and the definition of Trading Price set forth in this Supplemental Indenture. The Company shall provide
written notice to the Bid Solicitation Agent of the three independent nationally recognized securities dealers selected by the Company pursuant to the definition of Trading Price, along with appropriate contact information for each. The Bid
Solicitation Agent (if other than the Company) shall have no obligation to determine the Trading Price per $1,000 principal amount of Notes unless the Company has requested such determination, and the Company shall have no obligation to make such
request (or, if the Company is acting as Bid Solicitation Agent, the Company shall have no obligation to determine the Trading Price) unless a Holder of at least $1,000,000 aggregate principal amount of Notes provides the Company with reasonable
evidence that the Trading Price per $1,000 principal amount of Notes would be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate, at which time the Company shall instruct the Bid Solicitation
Agent (if other than the Company) to solicit, or if the Company is acting as Bid Solicitation Agent, the Company shall solicit, such bids beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000
principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate. The Company shall determine the Trading Price in accordance with the bids received by the Bid
Solicitation Agent. If (x) the Company is not acting as Bid Solicitation Agent and the Company does not, when the Company is required to, instruct the Bid Solicitation Agent to obtain bids, or if the Company gives such instruction to the Bid
Solicitation Agent, and the Bid Solicitation Agent fails to obtain bids or (y) the Company is acting 

  
 42 








 
as Bid Solicitation Agent and the Company fails to obtain bids, or the Company fails to make such determination, then, in either case, the Trading Price per $1,000 principal amount of Notes shall
be deemed to be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on each Trading Day of such failure. If the Trading Price condition set forth above has been met on any Trading Day, the Company
shall so notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) in writing within one Business Day of such Trading Day. If, at any time after the Trading Price condition set forth above has been met, the Trading Price
per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate for such Trading Day, the Company shall so notify the Holders of the Notes, the Trustee
and the Conversion Agent (if other than the Trustee) in writing that the Trading Price condition is no longer met and thereafter neither the Company nor the Bid Solicitation Agent shall be required to solicit bids again until another qualifying
request is made as provided in this Section. 
 (ii) If, prior to the close of business on the Business Day immediately
preceding June 1, 2024, the Company elects to: 
 (A) issue to all or substantially all holders of the Common Stock any
rights, options or warrants (other than pursuant to a stockholder rights plan, so long as such rights have not separated from the shares of Common Stock) 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; or 
 (B) distribute to all or substantially all
holders of the Common Stock the Company’s assets, securities or rights to purchase securities of the Company (other than pursuant to a stockholder rights plan, so long as such rights have not separated from the shares of Common Stock), which
distribution has a per share value, as reasonably determined by the Board of Directors, exceeding 10% of the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the date of announcement for such distribution, 

then, in either case, the Company shall notify all Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee) in writing (such
notification, the “Certain Distributions Notification”) at least 50 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution. Once the Company has given such
notice, a Holder may surrender all or any portion of its Notes for conversion at any time until the earlier of (1) the close of business on the Business Day immediately preceding the Ex-Dividend Date for
such issuance or distribution and (2) the Company’s announcement that such issuance or distribution will not take place (such earlier date and time, the “Certain Distributions Conversion Period End Date”). Notwithstanding
anything to the contrary in this Section 14.01(b)(ii), if in an applicable Certain Distributions Notification the Company elects Physical Settlement in respect of any conversions with Conversion Dates that occur from, and including, the date of
the Certain Distributions Notification to, and including, the Certain Distributions Conversion Period End Date, the Company shall be permitted to provide no more than 10 Scheduled Trading Days’ notice prior to the
Ex-Dividend Date for the applicable issuance or distribution. 

  
 43 








 (iii) If a transaction or event that constitutes a Fundamental Change or a
Make-Whole Fundamental Change (pursuant to clause (a) of the definition thereof) occurs prior to the close of business on the Business Day immediately preceding June 1, 2024, regardless of whether a Holder has the right to require the
Company to repurchase the Notes pursuant to Section 15.02, or if the Company is a party to a Share Exchange Event (other than any Share Exchange Event that is solely for the purpose of changing the Company’s jurisdiction of organization
that (x) does not constitute a Fundamental Change or a Make-Whole Fundamental Change (pursuant to clause (a) of the definition thereof) and (y) results in a reclassification, conversion or exchange of outstanding shares of Common
Stock solely into common equity of the surviving entity) that occurs prior to the close of business on the Business Day immediately preceding June 1, 2024 (each such Fundamental Change, Make-Whole Fundamental Change or Share Exchange Event, a
“Corporate Event”), all or any portion of a Holder’s Notes may be surrendered for conversion at any time from or after the effective date of the Corporate Event until the earlier of (x) 35 Trading Days after the effective date
of such Corporate Event or, if such Corporate Event also constitutes a Fundamental Change, until the close of business on the Business Day immediately preceding the related Fundamental Change Repurchase Date and (y) the Business Day immediately
preceding the Maturity Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) as promptly as practicable following the date the Company publicly announces the effective date of such Corporate Event,
but in no event later than the effective date of such Corporate Event. 
 (iv) Prior to the close of business on the Business
Day immediately preceding June 1, 2024, a Holder may surrender all or any portion of its Notes for conversion at any time during any calendar quarter commencing after the calendar quarter ending on December 31, 2017 (and only during such
calendar quarter), if the Last Reported Sale Price of the Common Stock for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on the last Trading Day of the immediately preceding calendar
quarter is greater than or equal to 130% of the Conversion Price on each applicable Trading Day. The Company shall determine at the beginning of each calendar quarter commencing after December 31, 2017 whether the Notes may be surrendered for
conversion in accordance with this clause (iv) and, if the Notes may be so surrendered for conversion, shall notify the Conversion Agent (if other than the Trustee) and the Trustee as such fact. 

(v) If the Company sends a Notice of Redemption pursuant to Article 16, a Holder may surrender all or any portion of its Notes,
to which such Notice of Redemption relates, for conversion during the period from and including the date the applicable Notice of Redemption was sent to close of business on the date that is the later of (1) the Business Day immediately
preceding the related Redemption Date and (2) if the Company fails to pay the Redemption Price on the Redemption Date as specified in such Notice of Redemption, such later date on which the Redemption Price is paid. 

Section 14.02. Conversion Procedure; Settlement Upon Conversion. 

  
 44 








 (a) Subject to this Section 14.02, Section 14.03(b) and Section 14.07(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 delivering any fractional share of Common Stock in accordance with subsection (j) of this Section 14.02 (“Physical Settlement”) or a combination of cash and shares of Common Stock,
together with cash, if applicable, in lieu of delivering any fractional share of Common Stock in accordance with subsection (j) of this Section 14.02 (“Combination Settlement”), at its election, as set forth in this
Section 14.02. 
 (i) All conversions for which the relevant Conversion Date occurs on or after June 1, 2024 shall
be settled using the same Settlement Method. 
 (ii) Subject to subclause (i), above and notwithstanding anything to the
contrary in subclause (iv) below, where a Notice of Redemption has been sent pursuant to Article 16, the Company will specify in the related Notice of Redemption the Settlement Method (and in the case of an election of Combination Settlement
the relevant Notice of Redemption shall indicate the Specified Dollar Amount) for all conversions with a Conversion Date occurring during the period from and including the date the Notice of Redemption was sent to the close of business on the date
that is the later of (1) the Business Day immediately preceding the related Redemption Date and (2) if the Company fails to pay the Redemption Price on the Redemption Date as specified in the Notice of Redemption, such later date on which
the Redemption Price is paid. 
 (iii) Except for any conversions for which the relevant Conversion Date occurs on or after
June 1, 2024, the Company shall use the same Settlement Method for all conversions with the same Conversion Date, but the Company shall not have any obligation to use the same Settlement Method with respect to conversions with different
Conversion Dates. 
 (iv) If, in respect of any Conversion Date (or the period described in the fourth immediately succeeding
set of parentheses, 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 shall
deliver such Settlement Notice to the Trustee, the Conversion Agent (if other than the Trustee) and converting Holders no later than the close of business on the second Trading Day immediately following the relevant Conversion Date (or, in the case
of any conversions for which the relevant Conversion Date occurs on or after June 1, 2024, no later than June 1, 2024). If the Company does not elect a Settlement Method 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 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 per $1,000 principal amount of Notes. If the Company delivers a Settlement Notice electing Combination Settlement in respect of its Conversion Obligation but does not indicate a Specified Dollar Amount per $1,000 principal amount of
Notes in such Settlement 

  
 45 








 
Notice, the Specified Dollar Amount per $1,000 principal amount of Notes shall be deemed to be $1,000. Notwithstanding anything to the contrary in this Section 14.02(a), the Company shall be
permitted to elect Physical Settlement in any Certain Distributions Notification as set forth in Section 14.01(b)(iii) and any such election shall be applicable to conversions with Conversion Dates that occur from the date of the Certain
Distributions Notification until the related Certain Distributions Conversion Period End Date. 
 (v) 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 40 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, 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 40 consecutive Trading Days during the related Observation Period. 
 (vi) 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 delivering any fractional share of Common Stock, 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 delivering 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) 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 procedures of the Depositary in effect at that time and, if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled and, if required, pay all transfer or similar
taxes, if any, as set forth in Section 14.02(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 

  
 46 








 
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, (4) if required, pay funds
equal to the interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 14.02(h) and (5) if required, pay all transfer or similar taxes. The Trustee (and if different, the Conversion
Agent) shall notify the Company of any conversion pursuant to this Article 14 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 has not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section 15.03. 

If more than one Note shall be surrendered for conversion at one time by the same Holder, the Conversion Obligation with respect to such Notes
shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted thereby) so surrendered. 

(c) A Note shall be deemed to have been converted immediately prior to the close of business on the date (the “Conversion
Date”) that the Holder has complied with the requirements set forth in subsection (b) above. Except as set forth in Section 14.03(b) and Section 14.07(a), the Company shall pay or deliver, as the case may be, the
consideration due in respect of the Conversion Obligation on the third Business Day immediately following the 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 Physical Note shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and
deliver to or upon the written order of the Holder of the Note so surrendered a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note, without payment of any service
charge by the converting Holder but, if required by the Company or Trustee, with payment of a sum sufficient to cover any documentary, stamp or similar issue or 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 any such shares to be issued in a name other than the Holder’s name, in which case the Holder shall pay that tax. 

  
 47 








 (f) Except as provided in Section 14.04, no adjustment shall be made for dividends on any
shares of Common Stock issued upon the conversion of any Note as provided in this Article 14. 
 (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 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 full 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 the close of business on a Regular Record Date but prior to the open of business on the immediately following Interest Payment Date, Holders of such Notes as of the close of business on such Regular Record Date shall
receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. However, Notes surrendered for conversion during the period from the close of business on any Regular Record Date to
the open of business on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of such interest payable on the Notes so converted on the corresponding Interest Payment Date (regardless of whether the
converting Holder was the Holder of record on the corresponding Regular Record Date); provided that no such payment shall be required (1) for conversions following the close of Business on 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 Business Day immediately following the corresponding Interest Payment Date, in respect of Notes converted after the
close of business on such Regular Record Date and on or prior to the Open of Business on such 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, in respect of Notes converted after the close of business on such Regular Record Date and on or prior to the Open of Business on such 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. Therefore, for the avoidance of doubt, all Holders of record on the Regular Record Date immediately preceding the
Maturity Date, Redemption Date and any Fundamental Change Repurchase Date described in subclauses (1), (2) and (3) above shall receive the full interest payment due on the Maturity Date or other applicable Interest Payment Date regardless of
whether their Notes have been converted, redeemed or repurchased, as applicable, following such Regular Record Date. 
 (i) The Person in
whose name the shares of Common Stock shall be issuable upon conversion shall become the holder of record of such shares as of the close of business 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 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. 

  
 48 








 (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 delivering any fractional share of Common Stock issuable upon conversion based on the Daily VWAP for the relevant Conversion Date (in the case of Physical Settlement) or based on the Daily VWAP for 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 relevant Observation Period and any fractional shares remaining after such computation shall be paid in cash. 

Section 14.03. 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 (i) in the case of a Make-Whole Fundamental Change pursuant to clause (a) of the definition thereof, the relevant Conversion Date occurs
during the period from, and including, the Effective Date of the Make-Whole Fundamental Change up to, and including, 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) and (ii) in the case
of a Make-Whole Fundamental Change pursuant to clause (b) of the definition thereof, the applicable Conversion Date occurs during the period from and including the date the applicable Notice of Redemption was sent to close of business on the
date that is the later of (1) the Business Day immediately preceding the related Redemption Date and (2) if the Company fails to pay the Redemption Price on the Redemption Date as specified in such Notice of Redemption, such later date on
which the Redemption Price is paid; provided, however, that if the Company sends a Notice of Redemption to call less than all of the Notes then Outstanding for redemption, then (x) a Make-Whole Fundamental Change will be
deemed to occur on account of such Notice of Redemption only with respect to the Notes called for such redemption, and not with respect to the Notes not called for such redemption; and (y) no such Notes that are not called for such redemption
will be deemed to be converted “in connection with” such Make-Whole Fundamental Change (each such period, in each of clauses (i) and (ii) above, a “Make-Whole Fundamental Change Period”). 

(b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change pursuant to Section 14.01(b)(iii), the
Company shall, at its option, satisfy the related Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with Section 14.02; 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 following such Make-Whole Fundamental Change is composed entirely of cash, for any conversion of Notes following the Effective
Date of such Make-Whole Fundamental 

  
 49 








 
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 pursuant to this Section 14.03), 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 Trustee, the Conversion Agent (if other than the Trustee) and the Holders of Notes of the Effective Date of any Make-Whole Fundamental Change no later than five Business Days after such Effective
Date. 
 (c) The amount, if any, by which the Conversion Rate shall be increased shall be determined by reference to the table below, based
on the Effective Date of the Make-Whole Fundamental Change and the price paid (or deemed to be paid) per share of the Common Stock in the Make-Whole Fundamental Change (the “Stock Price”). If the holders of the Common Stock receive
in exchange for their Common Stock 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 Company 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, Effective Date (as such term is used in Section 14.04) or expiration date of the event occurs during such five consecutive Trading Day period. In the event that a conversion in
connection with a Make-Whole Fundamental Change pursuant to clause (a) of the definition thereof would also be deemed to be in connection with a Make-Whole Fundamental Change pursuant to clause (b) of the definition thereof, a converting
Holder will be entitled to a single increase (if applicable) to the Conversion Rate with respect to the event giving rise to the first-occurring Effective Date, and the later event will be deemed not to have occurred for purposes of this
Section 14.03. 
 (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 amounts by which the Conversion Rate shall be increased as 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 14.04. 
 (e) The following table sets forth the
amount, if any, by which the Conversion Rate shall be increased per $1,000 principal amount of Notes pursuant to this Section 14.03 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 amount by which the Conversion Rate shall be increased shall be determined by a straight-line interpolation between the amount of the Conversion Rate increase 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 $140.00 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), the Conversion Rate shall not be increased; and 

(iii) if the Stock Price is less than $36.835 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), the Conversion Rate shall not be increased. 
 Notwithstanding the
foregoing, in no event shall the Conversion Rate per $1,000 principal amount of Notes exceed 27.1480 shares of Common Stock, subject to adjustment in the same manner as the Conversion Rate pursuant to Section 14.04. 

(f) Nothing in this Section 14.03 shall prevent an adjustment to the Conversion Rate pursuant to Section 14.04 in
respect of a Make-Whole Fundamental Change. 
 Section 14.04. 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 participate (other than in the case of (x) a share split or
share combination or (y) a tender or exchange offer), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions described in this Section 14.04, 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. 

  
 51 








 (a) If the Company exclusively issues shares of Common Stock as a dividend or distribution on
shares of the 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 the open of business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the open of business on the
Effective Date of such share split or share combination, as applicable;
			
	 CR1
	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date or Effective Date, as applicable;
			
	 OS0
	  	=	  	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date, as applicable, before giving effect to such dividend,
distribution, share split or share combination; and
			
	 OS1
	  	=	  	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 14.04(a) shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately after the open of business on the Effective Date for such share split or share combination, as applicable. If any dividend or distribution of the
type described in this Section 14.04(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 the Common Stock any rights, options or warrants (other than pursuant to a stockholder rights plan) 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 the open of business on the Ex-Dividend Date for such issuance;


  
 52 









					
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date;
			
	X	  	=	  	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
			
	Y	  	=	  	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 14.04(b) shall be made successively whenever any such rights, options or warrants
are issued and shall become effective immediately after the open of business on the Ex-Dividend Date for such issuance. To the extent that such rights, options or warrants are not exercised prior to their
expiration or 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 or if no such right, option or warrant is
exercised prior to its expiration, 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 14.04(b) and for the purpose of Section 14.01(b)(ii)(A), in determining whether any rights, options or
warrants entitle the holders to subscribe for or purchase shares of the Common Stock at a price per share that is less than 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 of 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 or will be so effected in
accordance with Section 14.04(j) pursuant to Section 14.04(a) or Section 14.04(b), (ii) except as otherwise provided in Section 14.11, rights issued pursuant to any stockholder rights plan of the Company then in effect,
(iii) dividends or distributions paid exclusively in cash as to which the provisions of Section 14.04(d) apply, (iv) dividends or distributions of Reference Property in exchange for or upon conversion of Common Stock in connection
with any Share Exchange Event, and (v) Spin-Offs as to which the provisions set forth below in this Section 14.04(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: 

  
 53 








 



 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on 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 14.04(c) above shall become effective immediately after the open of
business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the 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 14.04(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. 
 With respect to an adjustment pursuant to this Section 14.04(c) where there has been a payment of a dividend or
other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company, that are, or, when issued, will be, listed or admitted for
trading on a U.S. national securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula: 

  
 54 








 



 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the end of the Valuation Period;
			
	CR1	  	=	  	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 1.01 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 increase to the Conversion Rate under the preceding paragraph shall occur at the close of business on the last Trading Day
of the Valuation Period; provided that (x) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant Conversion Date occurs during the Valuation Period, the reference in the portion of this
Section 14.04(c) related to Spin-Offs to “10” shall be deemed replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date for such Spin-Off and such Conversion Date in determining the Conversion Rate and (y) in respect of any conversion of Notes for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that
falls within the relevant Observation Period for such conversion and within the Valuation Period, the reference in the portion of this Section 14.04(c) related to Spin-Offs to 10 shall be deemed replaced with such lesser number of Trading Days
as have elapsed between the Ex-Dividend Date for such Spin-Off and such Trading Day in determining the Conversion Rate as of such Trading Day. In addition, if the Ex-Dividend Date for such Spin-Off is after the 10th Trading Day immediately preceding, and including, the end of any Observation Period in respect of a conversion of Notes,
references in the preceding paragraph and this paragraph to “10” or “10th” shall be deemed to be replaced, solely in respect of that conversion of Notes, with such lesser number of Trading Days as have elapsed from, and
including, the Ex-Dividend Date for such Spin-Off to, and including, the last Trading Day of such Observation Period. If any dividend or distribution that constitutes a Spin-Off is declared but not so paid or made, the Conversion Rate shall be immediately decreased, 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 or announced. 
 For purposes of this
Section 14.04(c) (and subject in all respects to Section 14.11), rights, options or warrants distributed by the Company to all holders of the 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 

  
 55 








 
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 14.04(c) (and no adjustment to the Conversion Rate under this Section 14.04(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 14.04(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed
prior to the date of this Supplemental Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of
the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date with respect to new rights, options or warrants with such rights (in which case the existing
rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger
Event or other event (of the type described in the immediately preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this
Section 14.04(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 14.04(a),
Section 14.04(b) and this Section 14.04(c), if any dividend or distribution to which this Section 14.04(c) is applicable also includes one or both of: 

(A) a dividend or distribution of shares of Common Stock to which Section 14.04(a) is applicable (the “Clause A
Distribution”); or 
 (B) a dividend or distribution of rights, options or warrants to which Section 14.04(b) is applicable
(the “Clause B Distribution”), 
 then, in either case, (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 14.04(c) is applicable (the “Clause C Distribution”) and any Conversion Rate adjustment required by this Section 14.04(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 14.04(a) and Section 14.04(b) with respect thereto shall then be made, except that, if determined by the Company (I) the “Ex-Dividend Date” of the Clause A Distribution and the
Clause B Distribution shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (II) any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be
deemed not to be “outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date” within the meaning of Section 14.04(a) or “outstanding immediately prior
to the open of business on such Ex-Dividend Date” within the meaning of Section 14.04(b). 

  
 56 








 (d) If the Company pays or makes any cash dividend or distribution 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 the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on 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 to the Conversion Rate pursuant to this Section 14.04(d) shall become effective immediately after the open
of business 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 that is subject to the then-applicable tender offer rules under the Exchange Act, other than an odd lot tender offer, to the extent that the cash and value of
any other consideration included in the payment per share of the Common Stock exceeds 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 last date on which tenders or exchanges may be made pursuant to such tender or exchange offer (the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, the “expiration date”),
the Conversion Rate shall be increased based on the following formula: 

  
 57 








 



 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the expiration date;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the expiration date;
			
	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 or exchanged in such tender or exchange offer;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the expiration date (prior to giving effect to the purchase or exchange of all shares of Common Stock accepted for purchase or exchange in such tender or exchange
offer);
			
	OS1	  	=	  	the number of shares of Common Stock outstanding immediately after the expiration date (after giving effect to the purchase or exchange of all shares of Common Stock accepted for purchase or exchange in such tender or exchange
offer); and
			
	SP1	  	=	  	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 expiration date.

 The adjustment to the Conversion Rate under this Section 14.04(e) shall occur at the close of business on the 10th
Trading Day immediately following, and including, the Trading Day next succeeding the expiration date; provided that (x) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant Conversion Date
occurs during the 10 Trading Days immediately following, and including, the Trading Day next succeeding the expiration date, references to “10” or “10th” in the preceding paragraph shall be deemed replaced with such lesser number
of Trading Days as have elapsed between the expiration date and such Conversion Date in determining the Conversion Rate and (y) in respect of any conversion of Notes for which Cash Settlement or Combination Settlement is applicable, for any
Trading Day that falls within the relevant Observation Period for such conversion and within the 10 Trading Days immediately following, and including, the Trading Day next succeeding the expiration date, references in this Section 14.04(e) to
“10” or “10th” shall be deemed replaced with such lesser number of Trading Days as have elapsed between the expiration date and such Trading Day in determining the Conversion Rate as of such Trading Day. In addition, if the
Trading Day next succeeding the expiration date is after the 10th Trading Day immediately preceding, and including, the end of any Observation Period in respect of a conversion of Notes, references in the preceding paragraph and this paragraph to
“10” or “10th” shall be deemed to be replaced, solely in respect of that conversion of Notes, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the date such tender or
exchange offer expires to, and including, the last Trading Day of such Observation Period. 

  
 58 








 In the event that the Company or one of the Company’s Subsidiaries is obligated to purchase
shares of Common Stock pursuant to any such tender offer or exchange offer described in this Section 14.04(e), but the Company or such Subsidiary is permanently prevented by applicable law from effecting any such purchases, or all such
purchases are rescinded, then the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such tender offer or exchange offer had not been made or had been made only in respect of the purchases that have
been effected, as the case may be. 
 (f) Notwithstanding this Section 14.04 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 14.02(i) based on an adjusted Conversion Rate for such
Ex-Dividend Date, then, notwithstanding the Conversion Rate adjustment provisions in this Section 14.04, 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 the Common Stock or any securities convertible into or exchangeable for shares of the Common Stock or the right to purchase shares of the Common Stock or such convertible or exchangeable securities. 

(h) In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 14.04, and to the extent
permitted by applicable law and subject to the applicable rules of any exchange on which any of the Company’s securities are then listed, 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, to the extent permitted by applicable law and subject to the applicable rules of any exchange on which any of the
Company’s securities are then listed, 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 of Common Stock (or rights to acquire shares of Common Stock) or similar event. Whenever the Conversion Rate is increased pursuant to either of the preceding two sentences, the Company shall mail to the Holder of each Note at
its last address appearing on the Security 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 14, the Conversion Rate shall not be adjusted: 

  
 59 








 (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) upon the repurchase of any shares of Common Stock pursuant to an open-market share repurchase program or other buy-back transaction, including structured or derivative transactions, that is not a tender offer or exchange offer of the kind described in Section 14.04(e); 

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

(vi) for accrued and unpaid interest, if any. 

(j) All calculations and other determinations under this Article 14 shall be made by the Company and shall be made to the nearest one-ten thousandth (1/10,000th) of a share. If an adjustment to the Conversion Rate otherwise required by this Section 14.04 would result in a change of less than 1% to the Conversion Rate, then,
notwithstanding anything to the contrary in this Section 14.04, the Company may, at its election, defer and carry forward such adjustment, except that all such deferred adjustments must be given effect immediately upon the earliest to occur of
the following: (i) when all such deferred adjustments would result in an aggregate change of at least 1% to the Conversion Rate; (ii)the Conversion Date of (if Physical Settlement applies to such conversion), or each Trading Day of the
applicable Observation Period for (if Cash Settlement or Combination Settlement applies to such conversion), any Note; (iii) the date a Fundamental Change or Make-Whole Fundamental Change occurs; and (iv) June 1, 2024. 

(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 Security Register. Failure to deliver such notice shall not affect the legality or validity of any such adjustment. 

  
 60 








 (l) For purposes of this Section 14.04, the number of shares of Common Stock at any time
outstanding shall not include shares of Common Stock 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 of Common Stock issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. 

Section 14.05. 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, without limitation, an Observation Period and the period, if any, for determining the Stock Price for
purposes of a Make-Whole Fundamental Change), the Company shall, in good faith, make appropriate adjustments (to the extent no corresponding adjustment is otherwise made pursuant to Section 14.04) 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 (as such term is used in Section 14.04) or expiration date of
the event occurs at any time during the period when such Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts are to be calculated. 

Section 14.06. 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 (x) 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 and (y) the delivery of the maximum number of shares of Common Stock, including the maximum Conversion Rate increase pursuant to Section 14.03).

 Section 14.07. 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 share split,
share combination or change in par value), 
 (ii) any consolidation, merger or combination involving the Company, 

(iii) any sale, lease or other transfer to a third party of all or substantially all of the Company and the Company’s
Subsidiaries’ consolidated assets, taken as a whole, 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 “Share Exchange Event”), then, at and after the effective time of such Share Exchange 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 Share 

  
 61 








 
Exchange 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 Share Exchange Event and, prior to or at the effective time of such Share Exchange 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 10.02(f) 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 Share Exchange Event (A) the Company or the successor or acquiring company, as the case may be, 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 14.02 and (B) (I) any amount payable in cash upon conversion of the Notes in accordance with Section 14.02 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 14.02 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 Share Exchange Event and (III) the Daily VWAP and the Last Reported Sale Price, as applicable, shall be calculated based on the value of a unit of Reference Property. 

If the Share Exchange 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 (x) the weighted average of the types and amounts of
consideration received by the holders of Common Stock that affirmatively make such an election or (y) if no holders of Common Stock affirmatively make such an election, the types and amounts of consideration actually received by the holders of
Common Stock, 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 of the Common
Stock receive only cash in such Share Exchange Event, then for all conversions for which the relevant Conversion Date occurs after the effective date of such Share Exchange Event (A) 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 pursuant to Section 14.03), multiplied by the price paid per share of Common Stock in such
Share Exchange Event and (B) the Company shall satisfy the Conversion Obligation by paying such cash amount to converting Holders on the third Business Day immediately following the relevant 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. 

If the Reference Property in respect of any Share Exchange Event includes, in whole or in part, shares of common equity, the supplemental
indenture described in the second immediately preceding paragraph shall provide for anti-dilution and other adjustments that shall be as nearly equivalent as is possible to the adjustments provided for in this Article 14 with respect to the portion
of the Reference Property consisting of such common equity. If, in the case of any Share Exchange 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 company, as the case may be, in such Share Exchange Event, then such supplemental indenture shall also be executed by such other Person, if such other Person is an Affiliate of the Company or 

  
 62 








 
the successor or acquiring company, and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Directors shall reasonably consider necessary
by reason of the foregoing, including the provisions providing for the purchase rights set forth in Article 15. 
 (b) When the Company or
the successor or acquiring company, as applicable, executes a supplemental indenture pursuant to subsection (a) of this Section 14.07, the Company or the successor or acquiring company, as applicable, shall promptly file with the Trustee
an Officer’s Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or asset that will comprise a unit of Reference Property after any such Share Exchange 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 or the or the successor or acquiring company, as applicable, shall cause notice of the execution of such
supplemental indenture to be mailed to each Holder, at its address appearing on the Security 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 Share Exchange Event unless its terms are consistent with
this Section 14.07. 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 14.01 and Section 14.02 prior to the effective date of such Share Exchange Event. 
 (d) The above provisions of this
Section shall similarly apply to successive Share Exchange Events. 
 Section 14.08. 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, charges and preemptive rights 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 of Common Stock 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. 
 Section 14.09. Responsibility of Trustee. The Trustee and any other
Conversion Agent shall not at any time be under any duty or responsibility to any Holder to determine the 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 

  
 63 








 
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. Neither the Trustee nor any other Conversion Agent shall have any duty or responsibility whatsoever to determine compliance with the conversion procedures, or to make or confirm any calculations with respect to
the settlement provisions, of Section 14.02. 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 14.07 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 14.07 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.02 of the Base Indenture, may accept (without any independent investigation) as conclusive evidence of the
correctness of any such provisions, and shall be protected in relying upon, the Officer’s Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect
thereto. Neither the Trustee nor the Conversion Agent shall be responsible for determining whether any event contemplated by Section 14.01(b) has occurred that makes the Notes eligible for conversion or no longer eligible therefor until the
Company has delivered to the Trustee and the Conversion Agent the notices referred to in Section 14.01(b) with respect to the commencement or termination of such conversion rights, on which notices the Trustee and the Conversion Agent may
conclusively rely, and the Company agrees to deliver such notices to the Trustee and the Conversion Agent immediately after the occurrence of any such event or at such other times as shall be provided for in Section 14.01(b). The rights,
benefits and privileges of the Trustee set forth in the Base Indenture shall be applicable to the Conversion Agent, and the provisions set forth in Section 7.01 of the Base Indenture relating to the Trustee shall apply to the Conversion Agent.

 Section 14.10. Intentionally Omitted. 

Section 14.11. Stockholder Rights Plans. If the Company has a stockholder 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. However, if, prior to any conversion of Notes, the rights have separated from the shares of Common Stock in accordance with the
provisions of the applicable stockholder rights plan the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all or substantially all holders of the Common Stock Distributed Property as provided in
Section 14.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights. 

Section 14.12. Intentionally Omitted. 

  
 64 








 Section 14.13. Exchange in Lieu of Conversion. Notwithstanding anything herein
to the contrary, when a Holder surrenders Notes for conversion, the Company may, at its election (an “Exchange Election”), direct the Conversion Agent to surrender, on or prior to the second Trading Day following the Conversion
Date, such Notes to a financial institution designated by the Company for exchange in lieu of conversion. In order to accept any Notes surrendered for conversion, the designated financial institution must agree to timely deliver, in exchange for
such Notes, the shares of Common Stock, cash or combination thereof due upon conversion at the time and in the manner provided in this Article 14. If the Company makes an Exchange Election, the Company shall, by the close of business on the second
Trading Day following the relevant Conversion Date, notify the Holder surrendering Notes for conversion that the Company has made the Exchange Election and the Company shall notify the designated financial institution of the Settlement Method the
Company has elected with respect to such conversion and the relevant deadline for payment and/or delivery of the shares of Common Stock, cash or a combination thereof due upon conversion. 

Any Notes exchanged by the designated financial institution shall remain Outstanding. If the designated financial institution agrees to accept
any Notes for exchange but does not timely pay and/or deliver the shares of Common Stock, cash or a combination thereof due upon conversion, or if such designated financial institution does not accept the Notes for exchange, the Company shall pay
and/or deliver the shares of Common Stock, cash or a combination thereof due upon conversion to the converting Holder at the time and in the manner provided in this Article 14 as if the Company had not made an Exchange Election. 

The Company’s designation of a financial institution to which Notes may be submitted for exchange does not require the financial
institution to accept any Notes (unless the financial institution has separately made an agreement with the Company). The Company may, but is not obligated to, enter into a separate agreement with any designated financial institution that would
compensate it for any such transactions. 
 ARTICLE 15 

REPURCHASE OF NOTES AT OPTION OF
HOLDERS 
 Section 15.01. Intentionally Omitted. 

Section 15.02. Repurchase at Option of Holders Upon a Fundamental Change. (a) If a Fundamental Change occurs at any
time prior to the Maturity Date, each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes, or any portion thereof that is equal to $1,000 or an integral multiple of
$1,000, on the date (the “Fundamental Change Repurchase Date”) specified by the Company that is not less than 20 Business Days or more than 35 Business Days following the date of the Fundamental Change Company Notice, subject to
postponement to comply with applicable law, 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, but not including, such Interest Payment Date) 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 15. 

  
 65 








 (b) Repurchases of Notes under this Section 15.02 shall be made, at the option of the Holder
thereof, upon: 
 (i) delivery to the Paying Agent appointed to facilitate the repurchase 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, if the Notes are Physical Notes, or in compliance with the Depositary’s procedures for surrendering interests in
Global Notes, if the Notes are Global Notes, in each case prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date, subject to postponement to comply with applicable law; and 

(ii) delivery of the Notes, if the Notes are Physical Notes, to the Paying Agent appointed to facilitate the repurchase at any
time after delivery of the Fundamental Change Repurchase Notice (together with all necessary endorsements for transfer) at the office of the Paying Agent, or book-entry transfer of the Notes, if the Notes are Global Notes, in compliance with the
procedures of the Depositary, 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 appropriate
Depositary procedures. 
 Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change
Repurchase Notice contemplated by this Section 15.02 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close of business on the Business Day immediately preceding the
Fundamental Change Repurchase Date, subject to postponement to comply with applicable law, by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 15.03. 

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. 

  
 66 








 (c) On or before the 20th Business Day after the occurrence of the effective date of a
Fundamental Change, the Company shall provide to all Holders of Notes, the Trustee, the Conversion Agent (if other than 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. In the case of Physical Notes, such notice shall be by first
class mail or, in the case of Global Notes, such notice shall be delivered in accordance with the applicable procedures of the Depositary. Each Fundamental Change Company Notice shall specify: 

(i) the events causing the Fundamental Change; 

(ii) the effective date of the Fundamental Change; 

(iii) the last date on which a Holder may exercise the repurchase right pursuant to this Article 15; 

(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) 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 15.02. 
 At the Company’s request, the
Trustee shall give such notice in the Company’s name and at the Company’s expense; provided, however, that, in all cases, the text of such Fundamental Change 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 will 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 procedures of the Depositary shall be deemed to have been
cancelled, and, upon such return or cancellation, as the case may be, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn. 

  
 67 








 (e) Notwithstanding the foregoing, the Company shall not be required to purchase or make an offer
to purchase any Notes upon a Fundamental Change if a third party makes such an offer in the same manner, at the same time and otherwise in compliance with the requirements for an offer made by the Company as set forth in this Article 15 and such
third party purchases all Notes properly surrendered and not validly withdrawn under its offer in the same manner, at the same time and otherwise in compliance with the requirements for an offer made by the Company as set forth in this Article 15.

 (f) To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Article 15, the Company
shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under such provisions of this Article 15 by virtue of such conflict. 

Section 15.03. Withdrawal of Fundamental Change Repurchase Notice. (a) A Fundamental Change Repurchase Notice may be
withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Paying Agent in accordance with this Section 15.03 at any time prior to the close of business on the Business Day immediately preceding the Fundamental
Change Repurchase Date, subject to postponement to comply with applicable law, specifying: 
 (i) the principal amount of the
Notes with respect to which such notice of withdrawal is being submitted, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000, 

(ii) if Physical Notes have been issued, the certificate number of the Note in respect of which such notice of withdrawal is
being submitted, and 
 (iii) the principal amount, if any, of such Note that remains subject to the original 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 with appropriate procedures of the Depositary. 
 Section 15.04. Deposit of

 68 








 
15.02) and (ii) the time of book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the manner required by
Section 15.02 by mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in the Security Register; provided, however, that payments to the Depositary shall be made by wire transfer

have not been validly withdrawn, (i) such Notes shall cease to be Outstanding, (ii) interest shall 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 shall terminate (other than the right to receive the Fundamental Change Repurchase Price). 

(c) Upon surrender of a Physical Note that is to be repurchased in part pursuant to Section 15.02, the Company shall execute and the

(c) otherwise comply in all material respects with all federal and state securities laws in connection with any offer by the Company to
repurchase the Notes; 
 in each case, so as to permit the rights and obligations under this Article 15 to be exercised in the time and in the manner
specified in this Article 15. 
 ARTICLE 16 

REDEMPTION 

Section 16.01. Applicability of Article 3 of the Base Indenture. Article 3 of the Base Indenture shall not apply to the
Notes. Instead the provisions set forth in this Article 16 shall, with respect to the Notes, supersede in its entirety Article 3 of the 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 16 or the applicable provisions set forth in this Article 16, respectively.

 Section 16.02. No Redemption prior to September 1, 2021. Subject
to Section 16.03, the Notes shall not be redeemable by the Company prior to the Maturity Date, and no sinking fund is provided for the Notes. 

Section 16.03. Redemption on or after September 1, 2021. 

(a) Notwithstanding Section 16.02, on or after September 1, 2021 and prior to the Maturity Date, the Company may redeem for cash all
or part of the Notes at its option if the if the Last Reported Sale Price of Common Stock equals or exceeds 130% of the Conversion Price then in effect for at least 20 Trading Days (whether or not consecutive) during any 30 consecutive Trading Day
period ending within five Trading Days prior to the date on which the Company sends any Notice of Redemption. 
 (b) The redemption price of
each Note to be so redeemed will be equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon to, but excluding, the Redemption Date (or, if the Company Defaults in the payment of the Redemption Price, the day on
which such Default is no longer continuing) (the “Redemption Price”); provided that if the Redemption 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, but not including, such Interest Payment Date) to Holders of record as of such Regular Record Date, and the Redemption Price shall be equal to
100% of the principal amount of Notes to be redeemed pursuant to this Article 16. 
 (c) The sending of a Notice of Redemption pursuant to
this Article 16 will constitute a Make-Whole Fundamental Change with respect to any Note to which such Notice of Redemption relates. If the Notes are redeemed in part, sending of a Notice of Redemption will constitute a Make-Whole Fundamental Change
only with respect to the Notes to which such Notice of Redemption relates and no other Notes, and Holders of such other Notes will not be entitled to the benefits of Section 14.03. If a portion of a Note is subject to a Notice of Redemption and
such Note is converted in part in connection with the Make-Whole Fundamental Change, the converted portion of such Note will be deemed to be from the portion of such Note that was subject to the Notice of Redemption. 

(d) Not less than 50 nor more than 70 Scheduled Trading Days before the date of redemption (the “Redemption Date”), the
Company shall send to all Holders of Notes, the Trustee and the Paying Agent (in the case of a Paying Agent other than the Trustee) a written notice of any redemption (the “Notice of Redemption”) specifying: 

(i) the Redemption Date and any record date relating thereto; 

(ii) the Redemption Price; 

(iii) the applicable Conversion Rate and Conversion Price; 

(iv) that Notes called for redemption may be converted at any time before the close of business on the date that is the later
of (1) the Business Day immediately preceding the related Redemption Date and (2) if the Company fails to pay the Redemption Price on the Redemption Date as specified in the Notice of Redemption, such later date on which the Redemption
Price is paid; 
 (v) (w) that a Make-Whole Fundamental Change is deemed to occur with respect to each Note called for
redemption; (x) the amount that will be added to the Conversion Rate applicable to the conversion of any Note converted in connection with such Make-Whole Fundamental Change pursuant to Section 14.03; (y) the circumstances under which the
conversion of any Note called for redemption will be deemed to be “in connection with” such Make-Whole Fundamental Change; and (z) that the conversion of any Note that has not been called for redemption will not be deemed to be
“in connection with” such Make-Whole Fundamental Change; 
 (vi) the Settlement Method (and in the case of an
election of Combination Settlement the Specified Dollar Amount) for all conversions with a Conversion Date occurring during the period from and including the date the Notice of Redemption was sent to the close of business on the date that is the
later of (1) the Business Day immediately preceding the related Redemption Date and (2) if the Company fails to pay the Redemption Price on the Redemption Date as specified in the Notice of Redemption, such later date on which the
Redemption Price is paid; 
 (vii) that Holders who want to convert Notes must satisfy the requirements set forth therein and
in the Indenture; 
 (viii) the CUSIP number of the Notes, and that no representation is made as to the correctness or
accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes; 
 (ix) if the Notes are Physical Notes
and fewer than all the Notes Outstanding are to be redeemed, the certificate numbers and principal amounts of the particular Notes to be redeemed; 

(x) the section of the Indenture pursuant to which the Notes called for redemption are being redeemed; 

(xi) that, unless the Company defaults in making payment of the Redemption Price, interest on Notes or the portion of such
Notes called for redemption ceases to accrue on and after the Redemption Date; 
 (xii) the name and address of the Paying
Agent, if applicable; and 
 (xiii) that Notes called for redemption must be surrendered to the Paying Agent for cancellation
to collect the Redemption Price and/or any other procedures Holders must follow in connection with redemption of their Notes. 

Notwithstanding anything to the contrary in the foregoing, if, in a Notice of Redemption, the Company elects Physical Settlement for all
conversions with Conversion Dates that occur during the period specified in subsection (d)(vi), above, such Notice of Redemption may be given on not less than 30 nor more than 60 calendar days prior to the Redemption Date. 

  
 70 








 In the case of Physical Notes, the Notice of Redemption shall be by first class mail or, in the
case of Global Notes, such notice shall be sent in accordance with the applicable procedures of the Depositary. 
 At the Company’s
request given at least five Business Days prior to the delivery of such notice (unless a shorter period shall be satisfactory to the Trustee), the Trustee shall give any Notice of Redemption in the Company’s name and at the Company’s
expense; provided, however, that, in all cases, the text of such Notice of Redemption shall be prepared by the Company. 
 At
the time that any Notice of Redemption is provided, the Company will publish a notice containing the same information in a newspaper of general circulation in The City of New York or publish the information on the Company’s website or through
such other public medium as the Company may use at that time. 
 (e) If the Company elects to redeem all Notes Outstanding, it shall furnish
to the Trustee, at or prior to the date the Notice of Redemption is to be given to Holders, an Officer’s Certificate stating (a) the clause of the Indenture pursuant to which the redemption shall occur; (b) the Redemption Date;
(c) the principal amount of Notes to be redeemed; (d) the Redemption Price; (e) that such election has been duly authorized by all requisite corporate action on the part of the Company; and (f) that such election complies with
any applicable covenants or conditions precedent set forth in the Indenture. If the Company elects to redeem less than all Notes Outstanding, it shall furnish the above information to the Trustee at least five Business Days prior to the date the
related Notice of Redemption is to be sent to Holders of such redemption (unless a shorter period shall be satisfactory to the Trustee). Any proposed redemption may be cancelled by the Company upon written notice to the Trustee at any time prior to
any Notice of Redemption being sent to any Holder, and, thereafter, such proposed redemption shall be null and void. 
 (f) If less than all
the Notes are to be redeemed, the Trustee shall select, by lot or in such other manner as it shall deem appropriate and fair in its discretion (and subject to the applicable procedures of the Depositary) and that may provide for the selection of a
portion or portions (equal to $1,000 or any integral multiple thereof) of the principal amount of such Notes of a denomination larger than $1,000, the Notes to be redeemed and shall thereafter promptly notify the Company in writing of the numbers of
the Notes to be redeemed, in whole or in part. 
 (g) Notwithstanding the foregoing, no Notes may be redeemed by the Company on any date if
the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such date (except in the case of an acceleration resulting from a Default by the Company in the payment of the Redemption Price with
respect to such Notes). 
 Section 16.04. Effect of Notice of Redemption. Once a Notice of Redemption is given, Notes called for
redemption become due and payable on the Redemption Date and at the Redemption Price stated in the Notice of Redemption except for Notes that are converted in accordance with the terms of the Indenture. Upon surrender to the Paying Agent, such Notes
called for redemption shall be paid at the Redemption Price stated in the Notice of Redemption.

 Section 16.05. Deposit of Redemption 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 of the Base Indenture) on or prior to 11:00 a.m., New York City
time, on the Redemption Date an amount of money sufficient to redeem all of the Notes called for redemption at the appropriate Redemption Price. Subject to receipt of funds by the Trustee (or other Paying Agent appointed by the Company), payment of
Notes called for redemption will be made on the Redemption Date by mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in the Security 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 Redemption Price. 
 (b) If by 11:00 a.m. New York City time, on the Redemption 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 redeemed on such Redemption Date, then (i) such Notes shall cease to be Outstanding, (ii) interest shall cease to accrue
on such Notes and (iii) all other rights of the Holders of such Notes shall terminate (other than the right to receive the Redemption Price and, if applicable, interest as provided in the proviso to Section 16.03(b)). 

(c) Upon redemption of a Physical Note in part pursuant to Section 16.02, the Company shall execute and the Trustee shall authenticate and
deliver to the Holder a new Note in an authorized denomination equal in principal amount to the unredeemed portion of the Note.

 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 on the Fundamental Change Repurchase Date, the Redemption Price on the applicable Redemption Date 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 shall pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. 

The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the Holders of the
Notes, and in certain other circumstances, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time Outstanding, evidenced as in the Indenture provided, to execute supplemental indentures
modifying the terms of the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate principal amount of the Notes at the time Outstanding may on
behalf of the Holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences.

 No reference herein to the Indenture and no provision of this Note or of the Indenture shall
alter or impair the obligation of the Company, which is absolute and unconditional, to pay or deliver, as the case may be, the principal (including the Fundamental Change Repurchase Price and the Redemption Price, if applicable) of, accrued and
unpaid interest on, and the consideration due upon conversion of, this Note at the place, at the respective times, at the rate and in the lawful money herein prescribed. 

The Notes are issuable in registered form without coupons in minimum denominations of $1,000 principal amount and integral multiples of $1,000
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. 

On or after September 1, 2021 and prior to the Maturity Date, the Issuer may in certain circumstances specified in the Indenture redeem
all or part of the Notes. Other than as provided before, the Notes are not subject to redemption through the operation of any sinking fund or otherwise. 

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, during certain periods and upon the occurrence of
certain conditions specified in the Indenture, prior to the close of business on the Business Day immediately preceding the Maturity Date, to convert any Notes or portion thereof that is $1,000 or an integral multiple of $1,000 thereof, 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.
