matters referred to in this Section 1.03.

and the date of holding the same, shall be proved by the Registrar.

respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Note.

other Act, the Company may, at its option, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, election, waiver or other Act, but the Company shall have no
obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, election, waiver or other Act may be given before or after such record date, but only the Holders of record at the Close of
Business on the record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of the Outstanding Notes have authorized or agreed or consented to such request, demand, authorization, direction,
notice, consent, election, waiver or other Act, and for that purpose the Outstanding Notes shall be computed as of the record date; provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed
effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date.

 At the option of the Holder and subject to the other provisions of
Sections 2.07 and 2.11, Notes may be exchanged for other Notes of any authorized denomination and of a like aggregate principal amount and tenor, upon surrender of the Notes to be exchanged at such office or agency. Whenever any Notes are so
surrendered for exchange, the Company shall execute, and the Trustee shall, upon receipt of a Company Order, authenticate and deliver, the Notes which the Holder making the exchange is entitled to receive.

debt, and entitled to the same benefits under this Indenture, as the Notes surrendered upon such registration of transfer or exchange. 

Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Registrar) be
duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing. As a condition to the registration of
transfer of any Restricted Notes, the Company or the Registrar may require evidence satisfactory to them as to the compliance with the restrictions set forth in the legend on such Notes. 

No service charge shall be made for any registration of transfer or exchange of Notes, but the Company and the Registrar may require payment
of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes, other than exchanges pursuant to Section 2.11 not involving any transfer. 

Neither the Company nor the Registrar shall be required to exchange or register a transfer of any Note in the circumstances set forth in
Section 2.11(a)(iv).
 (b) Neither any members of, or participants in, the Depositary (collectively, the “Agent
Members”) nor any other Persons on whose behalf any Agent Member may act shall have any rights under this Indenture with respect to any Global Note registered in the name of the Depositary or any nominee thereof, or under any such Global
Note, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and Holder of such Global Note for all purposes whatsoever. The Trustee shall
have no liability, responsibility or obligation to any Agent Members or any other Person on whose 

  
 18 












 
behalf Agent Members may act with respect to (i) any ownership interests in the Global Note, (ii) the accuracy of the records of the Depositary or its nominee, (iii) any notice
required hereunder, (iv) any payments under or with respect to the Global Note (v) or actions taken or not taken by any Agent Members. 

(c) Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the
Trustee from giving effect to any written or electronic certification, proxy or other authorization furnished by the Depositary or such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other Person on
whose behalf an Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a Holder of any Note. The registered Holder of a Global Note may grant proxies and otherwise authorize any Person,
including Agent Members and Persons that may hold interests through Agent Members, to take any action that a Holder is entitled to take under this Indenture or the Notes.

Legend will be deemed to be “Restricted Stock”. Each share of Restricted Stock will be subject to the restrictions on transfer set forth in this Indenture (including the Restricted Stock Legend) and will bear a restricted CUSIP
number unless such restrictions on transfer are eliminated or otherwise waived by written consent (including, without limitation by the Company’s delivery of the Free Transferability Certificate as provided herein) of the Company, and each

the Restricted Stock Legend. 
 (iii) On and after the Resale Restriction Termination Date, shares of Common Stock issued
upon conversion of a Restricted Note will be issued in book-entry or certificated form (as determined by the Company) and will bear the Restricted Stock Legend at any time the Company reasonably determines that, to comply with law, such shares of
Common Stock must bear the Restricted Stock Legend. 

  
 20 












 (c) As used in this Section 2.07, the term “transfer”
means any sale, pledge, transfer, loan, hypothecation or other disposition whatsoever of any Restricted Note, any interest therein or any Restricted Stock. 

Section 2.08 Expiration of Restrictions. 

(a) Physical Notes. Any Physical Note (or any security issued in exchange or substitution therefor) that does not
constitute a Restricted Note may be exchanged for a new Note or Notes of like tenor and aggregate principal amount that do not bear the Restricted Notes Legend. To exercise such right of exchange, the Holder of such Note must surrender such Note in
accordance with the provisions of Section 2.11 and deliver any additional documentation reasonably required by the Company, the Trustee or the Registrar in connection with such exchange. 

(b) Restricted Global Notes; Resale Restriction Termination Date. 

(i) If, on the Free Trade Date, or the next succeeding Business Day if the Free Trade Date is not a Business Day, any Notes are

beneficial interests in Global Notes that are not subject to the restrictions set forth in the Restricted Notes Legend and in Section 2.07 hereof on or prior to the 365th day after the Issue Date. 

(ii) To effect such automatic exchange, the Company will (A) deliver to the Depositary an instruction letter for the
Depositary’s mandatory exchange process within a period of time that is reasonably likely to result in such exchange occurring on or prior to the 365th day after the Issue Date and (B) deliver to each of the Trustee and the Registrar a
duly completed Free Transferability Certificate promptly after the Free Trade Date. The first date on which both the Trustee and the Registrar have received the Free Transferability Certificate will be known as the “Resale Restriction
Termination Date”. 
 (iii) Immediately upon receipt of the Free Transferability Certificate by each of the Trustee
and the Registrar: 
 (A) the Restricted Notes Legend will be deemed removed from each of the Global Notes specified in such
Free Transferability Certificate and the restricted CUSIP number will be deemed removed from each of such Global Notes and deemed replaced with an unrestricted CUSIP number specified in the relevant Free Transferability Certificate; 

(B) the Restricted Stock Legend will be deemed removed from any shares of Common Stock previously issued upon conversion of the
Notes; and 
 (C) thereafter, shares of Common Stock issued upon conversion of the Notes will be assigned an unrestricted
CUSIP number and will not bear the Restricted Stock Legend (except as provided in Section 2.07(b)(iii)) or any similar legend. 

  
 21 












 (iv) Promptly after the Resale Restriction Termination Date, the Company
will provide Bloomberg LLP (if then generally in use) with a copy of the Free Transferability Certificate and will use reasonable efforts to cause Bloomberg LLP (if then generally in use) to adjust its screen page for the Notes to indicate that the
Notes are no longer Restricted Notes and are then identified by an unrestricted CUSIP number. 
 (v) Prior to the
Company’s delivery of the Free Transferability Certificate and afterwards, the Company and the Trustee will comply with the Applicable Procedures and the Company will otherwise use reasonable efforts to cause each Global Note to be identified
by an unrestricted CUSIP number in the facilities of the Depositary by the date the Free Transferability Certificate is delivered to the Trustee and the Registrar or as promptly as possible thereafter. 

(vi) Notwithstanding anything to the contrary in Sections 2.08(b)(i), (ii) or (iii), the Company will not be required
to deliver the Free Transferability Certificate if it reasonably believes that removal of the Restricted Notes Legend or the changes to the CUSIP numbers for the Notes could result in or facilitate transfers of the Notes in violation of applicable
law. 
 (vii) For the avoidance of doubt, a Global Note will not be “Freely Tradable” unless such Global Note is
identified by an unrestricted CUSIP number in the facilities of the Depositary. 
 Section 2.09 Mutilated, Destroyed, Lost and Stolen Notes If
any mutilated Note is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Note of like tenor and principal amount and bearing a number not contemporaneously Outstanding. If
there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Note and (ii) such security or indemnity as may be required by the Trustee (to protect the Trustee) and the
Company to save each of them and any agent of either of them harmless and such other reasonable requirements as may be imposed by the Company as permitted by Section 8-405 of the Uniform Commercial Code
have been satisfied, then, in the absence of notice to the Company or the Trustee that such Note has been acquired by a bona fide purchaser, the Company shall execute and the Trustee upon receipt of a Company Order shall authenticate and deliver, in
lieu of any such destroyed, lost or stolen Note, a new Note of like tenor and principal amount and bearing a number not contemporaneously Outstanding. 

In case any such mutilated, destroyed, lost or stolen Note has become or is about to become due and payable, the Company in its discretion
may, instead of issuing a new Note, pay such Note. 

  
 22 












 Upon the issuance of any new Note under this Section 2.09, the Company may require
payment by the Holder of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. 

Every new Note issued pursuant to this Section 2.09 in lieu of any destroyed, lost or stolen Note shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Notes
duly issued hereunder. 
 The provisions of this Section 2.09 are exclusive and shall preclude (to the extent lawful) all other rights
and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes. 
 Section 2.10 Persons Deemed
Owners. Prior to due presentment of a Note for registration of transfer, the Company, the Trustee, the Registrar and any agent of the Company, the Trustee or the Registrar may treat the Person in whose name such Note is registered in the

the Company, the Trustee or the Registrar shall be affected by notice to the contrary.

 23 












 (v) The Trustee in each of its capacities will have no obligation or duty to
monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Depositary

Note; 
 and, in each case, the Company promptly delivers a copy of such notice to the Trustee and the Company fails to appoint a successor

 24 












 In each such case, each Global Note will be deemed surrendered to the

credited with such increase. Upon the satisfaction of conditions (A), (B), (C) and (D), the Trustee will cancel such Physical Note and cause, or direct the Registrar to cause, in accordance with the Applicable Procedures, the aggregate principal
amount of Notes represented by such Global Note to be increased by the aggregate principal amount of such Physical Note, and will credit or cause to be credited the account of the Person specified in the instructions provided by the exchanging
Holder in an amount equal to the aggregate principal amount of such Physical Note. If no Global Notes are then Outstanding, the Company, in accordance with Section 2.04, will promptly use reasonable efforts to execute and deliver to the

any Notes previously authenticated and delivered hereunder that the Company may have acquired in any manner whatsoever, and may deliver to the Trustee for cancellation any Notes previously authenticated hereunder which the Company has not issued and
sold. The Trustee shall cancel all Notes surrendered for registration of transfer, exchange, payment, purchase, repurchase, conversion or cancellation in accordance with its customary practices. The Notes acquired by the Company, while held by or on
behalf of the Company or any of its Subsidiaries, shall not entitle the Holder thereof to convert the Notes. The Company may not issue new Notes to replace Notes it has paid in full or delivered to the Trustee for cancellation. The Company may from
time to time repurchase Notes in open market repurchases or negotiated transactions or otherwise without giving prior notice to Holders, whether by the Company or its subsidiaries or through a private or public tender or exchange offer or through
counterparties pursuant to private agreements, including by cash-settled swaps or other derivatives. The Company will cause any Notes so repurchased (other than Notes repurchased pursuant to cash-settled swaps or other derivatives that are not
physically settled) to be surrendered to the Trustee for cancellation, and they will no longer be Outstanding under this Indenture. 
 The
Registrar shall retain, in accordance with its customary procedures, copies of all letters, notices and other written communications received pursuant to this Section 2.12. The Company shall have the right to inspect and make copies of all such
letters, notices or other written communications at any reasonable time upon the giving of reasonable written notice to the Registrar. 
 Section 2.13
CUSIP Numbers. In issuing the Notes, the Company may use “CUSIP” numbers (if then generally in use); provided that the Trustee shall have no liability for any defect in the CUSIP numbers as they appear on any Notes, notice,
or elsewhere and; provided further, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes and that reliance may be placed only on the other identification
numbers printed on the Notes. The Company will promptly notify the Trustee in writing of any change in the “CUSIP” numbers. 
 Section 2.14
Payment and Computation of Interest. The Notes will bear cash interest at a rate of 0.50% per year until the Maturity Date or the date of any earlier conversion, redemption or repurchase. Interest on the Notes will accrue from the most recent
date on which interest has been paid or duly provided for or, if no interest has been paid or duly provided for (i) in the case of the Initial Notes, December 12, 2019 or (ii) in the case of the Additional Notes, the date provided
under such Notes. Interest will be paid to the Person in whose name a Note is registered at the Close of Business on the Regular Record Date immediately preceding the relevant Interest Payment Date semiannually in arrears on each Interest Payment
Date; provided, alternate record dates may be established by the Company and the Trustee with respect to any interest not paid on its originally scheduled due date. Interest on the Notes shall be computed on the basis of a 360-day year consisting of twelve 30-day months and, for partial months, on the basis of the number of days actually elapsed in a
30-day month. For the avoidance of doubt, the payment, or lack of payment, of interest on Notes surrendered for conversion will be governed by Section 4.03(d). 

  
 27 












 Section 2.15 Business Day. If any Interest Payment Date, the Maturity Date, any Redemption Date
or any Fundamental Change Repurchase Date falls on a day that is not a Business Day, the required payment will be made on the next succeeding Business Day and no interest on such payment will accrue in respect of the delay. 

ARTICLE 3. 
 REPURCHASE AT THE
OPTION OF THE HOLDERS 
 Section 3.01 Repurchase at Option of Holders upon a Fundamental Change. If a Fundamental Change occurs at any time
prior to the Maturity Date, then each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for cash all or any portion of such Holder’s Notes such that the remaining principal amount of each Note that
is not repurchased in full equals $1,000 or an integral multiple of $1,000 in excess thereof, on a 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 on which the Company delivers the Fundamental Change Company Notice, at a repurchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon, if any, to, but excluding, the
Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”); provided, however, that if the Company repurchases a Note on a Fundamental Change Repurchase Date that is after a Regular Record Date and
on or prior to the Interest Payment Date corresponding to such Regular Record Date, the Company shall instead pay the full amount of such accrued and unpaid interest on such Note on the Interest Payment Date to the Holder of record of such Note as
of such Regular Record Date and the Fundamental Change Repurchase Price shall then be equal to 100% of the principal amount of the Note the Company repurchases on such Fundamental Change Repurchase Date; provided, further, that the
Fundamental Change Repurchase Date may be postponed to allow the Company to comply with applicable law as a result of changes to such applicable law occurring after the date hereof. Notwithstanding the foregoing, there shall be no repurchase of any
Notes pursuant to this Section 3.01 if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to the Fundamental Change Repurchase Date (except in the case of an acceleration resulting
from a Default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes). The Paying Agent 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) and shall deem to be cancelled any instructions for book-entry transfer of the
Notes in compliance with the Applicable Procedures, in which case, 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. 

Section 3.02 Fundamental Change Company Notice. 

General. Promptly (but in no event later than ten Business Days) after the occurrence of a Fundamental Change, the Company shall provide
to all Holders of the Notes, the Trustee and the Paying Agent (in the case of any Paying Agent other than the Trustee) a written notice (the “Fundamental Change Company Notice”) of the occurrence of such Fundamental Change and


  
 28 












 
of the repurchase right at the option of the Holders arising as a result thereof. Such notice shall be sent by first class mail or, in the case of any Global Notes, in accordance with the
Applicable Procedures for providing notices. Simultaneously with providing such Fundamental Change Company Notice, the Company shall publish a press release or publish such information on the Company’s website. 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 of Notes may exercise the repurchase right pursuant to Section 3.01; 

(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) the applicable Conversion Rate and any adjustments to the applicable Conversion Rate resulting from the Fundamental
Change; 
 (viii) whether such Fundamental Change also constitutes a Make-Whole Fundamental Change; 

(ix) if applicable, that the Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by a Holder
may be converted only if the Holder withdraws the Fundamental Change Repurchase Notice in accordance with this Indenture; 

(x) that the Holder must exercise the repurchase right prior to the Fundamental Change Expiration Time; 

(xi) that the Holder shall have the right to withdraw any Notes surrendered for repurchase prior to the Fundamental Change
Expiration Time; and 
 (xii) the procedures that Holders must follow to require the Company to repurchase their Notes. 

(b) 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 Section 3.01. 
 (c) At the
Company’s written 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; provided, further that the Company shall have delivered to the Trustee, at least five (5) Business Days before the Fundamental Change Company Notice is required to be mailed (or such shorter period agreed
to by the Trustee), an Officer’s Certificate requesting that the Trustee give such notice and setting forth the complete form of such notice and the information to be stated in such notice. Neither the Trustee nor the Paying Agent shall be
responsible for determining if a Fundamental Change has occurred or for delivering a Fundamental Change Company Notice to Holders. 

  
 29

Change pursuant to clause (1)) if (1) such Fundamental Change results in the Notes becoming convertible (pursuant to the provisions of Section 4.07) into an amount of cash per $1,000 principal amount of Notes (which is a fixed aggregate
amount of cash that is required to be delivered upon conversion under the supplemental indenture for such Fundamental Change, excluding any cash payable as a result of any Settlement Method Election or cash paid in lieu of fractional shares) that is
greater than the Fundamental Change Repurchase Price per $1,000 principal amount of Notes (assuming the maximum amount of accrued interest would be payable based on the latest possible Fundamental Change Repurchase Date) and (2) the Company
provides timely notice of the Holders’ right to convert their Notes based on such Fundamental Change as described above under Section 4.01(b)(iv). 

  
 30 












 (a) Notice to Company. 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. 
 Section 3.04 Effect of
Fundamental Change Repurchase Notice. Upon receipt by the Paying Agent of a Fundamental Change Repurchase Notice specified in Section 3.03, the Holder of the Note in respect of which such Fundamental Change Repurchase Notice was given shall
(unless such Fundamental Change Repurchase Notice is withdrawn in accordance with Section 3.05) thereafter be entitled to receive solely the Fundamental Change Repurchase Price in cash with respect to such Note (and any previously accrued and
unpaid interest on such Note). Such Fundamental Change Repurchase Price shall be paid to such Holder, subject to receipt of funds by the Paying Agent, on the later of (x) the applicable Fundamental Change Repurchase Date (provided the
conditions in this Article 3 have been satisfied) and (y) the time of delivery or book-entry transfer of such Note to the Paying Agent by the Holder thereof in the manner required by Section 3.01. 

Section 3.05 Withdrawal of Fundamental Change Repurchase Notice. 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 and the Trustee in accordance with the Fundamental Change Company Notice at any time prior to the Fundamental Change Expiration Time specifying: 

(a) the principal amount of the Notes with respect to which such notice of withdrawal is being submitted; 

(b) if certificated, the certificate numbers of the withdrawn Notes; and 

(c) the principal amount, if any, of each Note that remains subject to the Fundamental Change Repurchase Notice which must be
such that the principal amount not to be repurchased equals $1,000 or an integral multiple of $1,000 in excess thereof; 
 provided, however,
that if the Notes are Global Notes, the notice must comply with the Applicable Procedures. 
 The Paying Agent will promptly return to the
respective Holders thereof any Physical Notes with respect to which a Fundamental Change Repurchase Notice, has been withdrawn in compliance with the provisions of this Section 3.05. 

Section 3.06 Deposit of Fundamental Change Repurchase Price. Prior to 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date
the Company shall deposit with the Paying Agent (or, if the Company or a Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust as provided herein) an amount of money (in immediately available
funds if deposited on such Business Day) sufficient to pay the Fundamental Change Repurchase Price of all the Notes or portions thereof that are to be repurchased as of the Fundamental Change Repurchase Date. If the Paying Agent holds cash


  
 31 












 
sufficient to pay the Fundamental Change Repurchase Price of the Notes for which a Fundamental Change Repurchase Notice has been delivered and not withdrawn in accordance with this Indenture on
the Fundamental Change Repurchase Date then as of such Fundamental Change Repurchase Date, with respect to the Notes that have been property surrendered for repurchase and have not been fully withdrawn: (a) such Notes will cease to be
Outstanding and interest will cease to accrue thereon (whether or not book-entry transfer of such Notes is made or such Notes have been delivered to the Paying Agent) and (b) all other rights of the Holders in respect thereof will terminate
(other than the right to receive the Fundamental Change Repurchase Price and any previously accrued and unpaid interest on such Notes upon delivery or book-entry transfer of such Notes). 

Section 3.07 Notes Repurchased in Whole or in Part. Any Note that is to be repurchased pursuant to this Article 3, whether in whole or in
part, shall be surrendered at the office of the Paying Agent (with due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly
authorized in writing) and, to the extent that only a part of the Note so surrendered is to be repurchased, the Company shall execute and, upon receipt of a Company Order, the Trustee shall authenticate and deliver to the Holder of such Note,
without service charge, a new Note or Notes, of any authorized denomination as requested by such Holder in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Note so surrendered that is not
repurchased. 
 Section 3.08 Covenant To Comply with Applicable Laws upon Repurchase of Notes. In connection with any offer to repurchase
Notes under Section 3.01, the Company shall, in each case if required by law (i) comply with the provisions of the tender offer rules under the Exchange Act that may then be applicable, (ii) file a Schedule TO or any other required
schedule under the Exchange Act and (iii) otherwise comply with all U.S. federal or state securities laws applicable to the Company in connection with such repurchase offer, in each case, so as to permit the rights and obligations under this
Article 3 to be exercised in the time and in the manner specified under this Article 3. 
 Section 3.09 Repayment to the Company. To the
extent that the aggregate amount of cash deposited by the Company pursuant to Section 3.06 exceeds the aggregate Fundamental Change Repurchase Price of the Notes or portions thereof that the Company is obligated to repurchase as of the
Fundamental Change Repurchase Date then, following the Fundamental Change Repurchase Date the Paying Agent shall promptly return any such excess to the Company. 

Section 3.10 Satisfaction of the Company’s Fundamental Change Repurchase Obligations. Notwithstanding anything to the contrary
contained in this Article 3, in the case of a Fundamental Change pursuant to clauses (1) and/or (2) of the definition thereof, the Company will not be required to make an offer to repurchase Notes upon the occurrence of such Fundamental
Change as would otherwise be required to the extent, and solely to the extent, that the other party to such Fundamental Change (or its Affiliate) (i) makes such an offer to purchase the Notes in the same manner, at the same time and otherwise
in compliance with the requirements set forth herein that would be applicable to such an offer by the Company (including, without limitation, the requirement to comply with applicable securities laws) and (ii) purchases all Notes properly
tendered and not validly withdrawn under such offer to repurchase 

  
 32 












 
all in compliance with the requirements set forth herein (including, without limitation, the requirement to pay the applicable Fundamental Change Repurchase Price on the later of the applicable
Fundamental Change Repurchase Date and the time of book-entry transfer or delivery of the relevant Notes); provided that, the Company will continue to be obligated to (x) deliver the applicable Fundamental Change Company Notice to the Holders,
the Trustee and the Paying Agent (which Fundamental Change Company Notice, in addition to the requirements set forth above, will state that such party will make such an offer to purchase the Notes) and to, simultaneously with such Fundamental Change
Company Notice, issue a press release containing such information or make such information available on the Company’s website, in each case, in the event such party fails to give such notice or issue such press release or make such information
available on its website, as applicable, (y) comply with applicable securities laws in connection with any such purchase and (z) pay the applicable Fundamental Change Repurchase Price on the later of the applicable Fundamental Change
Repurchase Date and the time of book-entry transfer or delivery of the relevant Notes in the event such party fails to make such payment in such amount at such time. The provisions of this paragraph will be limited to the matters set forth above and
shall not be deemed or otherwise construed to (a) limit any of the Company’s obligations under this Indenture or the Notes (except solely to the extent expressly set forth in this paragraph and subject to the conditions set forth above in
this paragraph) or (b) prejudice any right, power or remedy which the Trustee or Holders of the Notes may then have or may have in the future under or in connection with this Indenture or the Notes. 

ARTICLE 4. 
 CONVERSION 

Section 4.01 Right to Convert(a) . (a) Subject to and upon compliance with the provisions of the Indenture, each Holder shall have the right,
at such Holder’s option, to convert any or all of its Notes, or any portion thereof, such that the principal amount that remains Outstanding of each Note that is not converted in full equals $1,000 or an integral multiple of $1,000 in excess
thereof, into the Settlement Amount determined in accordance with Section 4.03(a)(ii) hereof, (x) prior to the Close of Business on the Business Day immediately preceding September 15, 2026, only upon satisfaction of one or more of
the conditions described in Section 4.01(b) hereof, and (y) on or after September 15, 2026, until the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date regardless of the conditions described
in Section 4.01(b) hereof. 
 (b) (i) Prior to the Close of Business on the Business Day immediately preceding September 15,
2026, a Holder may surrender all or a portion of its Notes for conversion during any fiscal quarter commencing after March 28, 2020 (and only during such fiscal 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 fiscal quarter is greater than or equal to 130% of the applicable Conversion Price for the Notes
in effect on each applicable Trading Day. 

  
 33 












 (ii) Prior to the Close of Business on the Business Day immediately
preceding September 15, 2026, a Holder may surrender all or a portion of its Notes for conversion at any time during the five consecutive Business Day period 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 such Notes in accordance with the procedures set forth in this Section 4.01(b)(ii), for each Trading Day of such
Measurement Period was less than 98% of the product of (x) the Last Reported Sale Price of the Common Stock on each such Trading Day and (y) the Conversion Rate for the Notes in effect on each such Trading Day. The Trading Price shall be
determined by the Company or the Bid Solicitation Agent, as applicable, pursuant to this Section 4.01(b)(ii) and the definition of “Trading Price” set forth in Section 1.01 hereof. The Company shall provide written notice to the
Bid Solicitation Agent of the three independent nationally recognized securities dealers selected by the Company in accordance with the definition of Trading Price, along with the appropriate contact information for each, and shall direct those
securities dealers to provide bids to the Bid Solicitation Agent. The Bid Solicitation Agent (if other than the Company) shall have no obligation to solicit bids in respect of the Notes unless the Company has requested that it do so; 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 solicit bids in respect of the Notes) unless a Holder of at least $2,000,000 principal amount of Notes (or
such lesser principal amount of notes as may then be outstanding) provides it with reasonable evidence that the Trading Price per $1,000 principal amount of Notes would be less than 98% of the product of (x) the Last Reported Sale Price of the
Common Stock on such Trading Day and (y) the Conversion Rate in effect on such Trading Day and such Holder, if the Company is not acting as the Bid Solicitation Agent, requests that the Company request that the Bid Solicitation Agent determine,
or, if the Company is acting as the Bid Solicitation Agent, requests that the Company determine, the Trading Price of the Notes. At such time, the Company shall instruct the Bid Solicitation Agent (if other than the Company) to solicit such bids and
the Company shall determine the Trading Price per $1,000 principal amount of the Notes (or, if the Company is acting as Bid Solicitation Agent, it shall determine the Trading Price per $1,000 principal amount of the Notes) beginning on the next
Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes for a Trading Day is greater than or equal to 98% of the product of (x) the Last Reported Sale Price of the Common Stock on such Trading
Day and (y) the Conversion Rate in effect on such Trading Day. Whenever the condition to conversion set forth in this Section 4.01(b)(ii) has been met, the Company shall so notify in writing the Holders, the Trustee and the Conversion
Agent (if other than the Trustee). If, at any time after the condition to conversion set forth in this Section 4.01(b)(ii) has been met, the condition to conversion set forth in this Section 4.01(b) (ii) ceases to be met, the Company
will so notify in writing the Holders, the Trustee and the Conversion Agent (if other than the Trustee). The Trustee shall have no obligation to determine the Trading Price of the Notes. 

  
 34 












 (iii) If the Company (x) issues to all or substantially all holders of
the Common Stock any rights, options or warrants (other than any issuance of any rights, options or warrants issued under a stockholder rights plan that are (A) transferable with shares of Common Stock, including shares of Common Stock
delivered upon conversion, and (B) not exercisable until the occurrence of a triggering event; provided that such rights, options or warrants will be deemed issued under this subclause (x) upon the separation of such rights, options
or warrants from the Common Stock, or upon the occurrence of such triggering event) entitling them for a period of not more than 60 calendar days after the date of such issuance to subscribe for or purchase shares of the Common Stock, at a price per
share less that is 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
(y) distributes to all or substantially all holders of the Common Stock the Company’s assets, debt securities or rights to purchase the Company’s securities (other than (A) rights described in the immediately preceding subclause
(x) or (B) any issuance of any rights, options or warrants issued under a stockholder rights plan that are (1) transferable with shares of Common Stock, including shares of Common Stock delivered upon conversion, and (2) not
exercisable until the occurrence of a triggering event), which distribution has a per share value, as reasonably determined by the Company in good faith and in a commercially reasonable manner, exceeding 10% of the Last Reported Sale Price of the
Common Stock on the Trading Day immediately preceding the date of announcement of such distribution, then, in either case, the Company must deliver notice in writing of such issuance or distribution, and of the
Ex-Dividend Date for such issuance or distribution, to the Holders, the Trustee and the Conversion Agent at least 45 Scheduled Trading Days prior to the Ex-Dividend Date
for such issuance or distribution. After the Company has delivered such notice, Holders may surrender all or any portion of their Notes to the Conversion Agent for conversion at any time until the earlier of (a) Close of Business on the
Business Day immediately preceding such Ex-Dividend Date and (b) the Company’s announcement that such issuance or distribution will not take place, even if the Notes are not otherwise convertible at
such time. Holders may not exercise this right if they participate (other than in the case of a share split or share combination), at the same time and upon the same terms as holders of Common Stock and solely as a result of holding the Notes, in
any of the transactions described above without having to convert their Notes as if they held a number of shares of Common Stock equal to the applicable Conversion Rate multiplied by the principal amount (expressed in thousands) of Notes held by
such Holder. 
 (iv) If (A) a transaction or event constituting a Fundamental Change or a Make-Whole Fundamental Change
occurs, (regardless of whether the Holders would have the right to require the Company to purchase their Notes pursuant to Article 3), or (B) the Company is a party to a consolidation, merger, binding share exchange, or transfer or lease of all
or substantially all of its assets (other than a merger effected solely to change the Company’s jurisdiction of incorporation solely within the United States) that (I) does not otherwise constitute a Fundamental Change or a Make-Whole
Fundamental Change and (II) results in a reclassification, conversion or exchange of outstanding shares of the Company’s 

  
 35 












 
Common Stock solely into common stock of the surviving entity, which shares are listed on the New York Stock Exchange, The NASDAQ Global Market or The NASDAQ Global Select Market (or any of their
respective successors), and such successor entity is a corporation organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, that occurs prior to the Close of Business on the Business Day
immediately preceding September 15, 2026, and pursuant to which the Common Stock would be converted to cash, securities or other assets, then, in each case, 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 transaction until the 35th Trading Day after such effective date or, if such transaction also constitutes a Fundamental Change, until the related Fundamental Change Repurchase Date. The Company will
notify in writing Holders, the Trustee and the Conversion Agent (if other than the Trustee) no later than the actual Effective Date of such transaction. The Trustee shall have no duty to determine whether any of the conditions to conversion have
occurred. 
 (v) If the Company calls any or all of the Notes for redemption pursuant to Article 11, then a Holder may
surrender all or any portion of such Holder’s Notes for conversion at any time prior to the Close of Business on the second Business Day immediately preceding the Redemption Date, even if the Notes are not otherwise convertible at such time.
After that time, the right to convert Notes on account of the Company’s delivery of the Redemption Notice shall expire, unless the Company defaults in the payment of the Redemption Price, in which case a Holder of Notes may convert all or any
portion of its Notes until the Close of Business on the Business Day immediately preceding the date on which the Redemption Price has been paid or duly provided for. 

Section 4.02 Conversion Procedures. 

(a) Each Note shall be convertible at the office of the Conversion Agent and, if applicable, in accordance with the Applicable
Procedures. 
 (b) To exercise the conversion privilege with respect to a beneficial interest in a Global Note, the Holder
must comply with the Applicable Procedures for converting a beneficial interest on a Global Note and pay the funds, if any, required by Section 4.02(f) and any taxes or duties if required pursuant to Section 4.02(g), and the Conversion
Agent must be informed of the conversion in accordance with the customary practice of the Depositary. 
 To exercise the
conversion privilege with respect to any Physical Notes, the Holder of such Physical Notes shall: 
 (i) complete and
manually sign a conversion notice in the form set forth in the Form of Notice of Conversion (the “Conversion Notice”) or a facsimile of the Conversion Notice; 

  
 36 












 (ii) deliver the Conversion Notice, which is irrevocable, and the Physical
Note to the Conversion Agent; 
 (iii) if required, furnish appropriate endorsements and transfer documents; 

(iv) if required, pay all transfer or similar governmental charges or duties as set forth in Section 4.02(g); and 

(v) if required, make any payment required under Section 4.02(f). 

If a Note has been submitted for repurchase pursuant to a Fundamental Change Repurchase Notice such Note may not be converted except to the
extent such Note has been withdrawn by the Holder and is no longer submitted for repurchase pursuant to a Fundamental Change Repurchase Notice or unless such Fundamental Change Repurchase Notice is withdrawn in accordance with Section 3.05
hereof prior to the relevant Fundamental Change Expiration Time. If a Holder submits its Notes for required repurchase, the Holder’s right to withdraw the Fundamental Change Repurchase Notice and convert the Notes that are subject to repurchase
will terminate at the Close of Business on the Business Day immediately preceding the relevant Fundamental Change Repurchase Date. 
 For
any Note, the date on which the Holder of such Note satisfies all of the applicable requirements set forth above with respect to such Note shall be the “Conversion Date” with respect to such Note. 

Each conversion shall be deemed to have been effected as to any such Notes (or portion thereof) surrendered for conversion at the Close of
Business on the applicable Conversion Date; provided, however, that except to the extent required by Section 4.04 hereof, the Person in whose name any shares of Common Stock shall be issuable upon conversion, if any, shall be
treated as a stockholder of record (i) as of the Close of Business on the last VWAP Trading Day of the applicable Observation Period in the case of Combination Settlement and (ii) as of the Close of Business on the Conversion Date in the
case of Physical Settlement. For the avoidance of doubt, until a Holder is deemed to become the holder of record of shares of Common Stock issuable upon conversion of such Holder’s Notes as contemplated in the immediately preceding sentence,
such Holder shall not have any rights as a holder of the Common Stock with respect to the shares of Common Stock issuable upon conversion of such Notes. At the Close of Business on the Conversion Date for a Note, the converting Holder shall no
longer be the Holder of such Note. 
 (c) Endorsement. Any Notes surrendered for conversion shall, unless shares of
Common Stock issuable on conversion are to be issued in the same name as the registration of such Notes, be duly endorsed by, or be accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the Holder or its duly
authorized attorney. 
 (d) Physical Notes. If any Physical Notes in a denomination greater than $1,000 shall be
surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of the Physical Notes so surrendered, without charge, new Physical Notes in authorized denominations in an aggregate principal
amount equal to the unconverted portion of the surrendered Physical Notes. 

  
 37 












 (e) Global Notes. Upon the conversion of a beneficial interest in
Global Notes, the Conversion Agent shall make a notation in its records as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversions of Notes effected through any Conversion
Agent other than the Trustee. 
 (f) Interest Due Upon Conversion. If a Holder converts a Note after the Close of
Business on a Regular Record Date but prior to the Open of Business on the Interest Payment Date corresponding to such Regular Record Date, such Holder must accompany such Note with an amount of cash equal to the amount of interest that will be
payable on such Note on the corresponding Interest Payment Date; provided, however, that a Holder need not make such payment (1) if the Conversion Date occurs after 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 second Business Day immediately following the corresponding Interest Payment Date; (3) if the
Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the Business Day immediately following the corresponding Interest Payment Date; or (4) to the extent of any overdue interest, if
any overdue interest exists at the time of conversion with respect to such Notes. 
 (g) Taxes Due upon Conversion. If
a Holder converts a Note, the Company will pay any documentary, stamp or similar issue or transfer tax due on the issue of any shares of the Common Stock upon the conversion, unless the tax is due because the Holder requests that any shares be
issued in a name other than the Holder’s name, in which case the Holder will be required to pay that tax. 
 Section 4.03 Settlement Upon
Conversion. 
 (a) Settlement. Subject to this Section 4.03 and Sections 4.04 and 4.06 hereof, upon
conversion of any Note, the Company shall pay or deliver, as the case may be, to Holders, in full satisfaction of its conversion obligation under Section 4.01 hereof, in respect of each $1,000 principal amount of Notes being converted, a
Settlement Amount consisting of, at the election of the Company, solely cash (“Cash Settlement”), solely shares of Common Stock (together with cash in lieu of delivering any fractional share of Common Stock pursuant to
Section 4.03(b)) (“Physical Settlement”) or a combination of cash and shares of Common Stock (“Combination Settlement”). 

(i) Settlement Election. All conversions for which the relevant Conversion Date occurs on or after September 15,
2026, and all conversions for which the relevant Conversion Date occurs after the Company’s issuance of a Redemption Notice and on or prior to the second Business Day before the related Redemption Date, shall be settled using the same
Settlement Method; provided that if such related Redemption Date is on or after September 15, 2026, then such 

  
 38 












 
Settlement Method must be the same Settlement Method that applies to all conversions with a Conversion Date that occurs on or after September 15, 2026. Except for any conversions for which
the relevant Conversion Date occurs after the Company’s issuance of a Redemption Notice but on or prior to the second Business Day before the related Redemption Date, and any conversions for which the relevant Conversion Date occurs on or after
September 15, 2026, the Company shall use the same Settlement Method for all conversions occurring on the same Conversion Date, but the Company shall not have any obligation to use the same Settlement Method with respect to conversions that
occur on different Conversion Dates. If the Company elects a Settlement Method (a “Settlement Election”) and a Specified Dollar Amount, if applicable (a “Specified Dollar Amount Election”), the Company shall provide
to the Holders so converting, the Conversion Agent and the Trustee a notice of such Settlement Method (each such notice, a “Settlement Election Notice”) or such Specified Dollar Amount (each such notice, a “Specified Dollar
Amount Election Notice”) no later than the Close of Business on the Business Day immediately following the related Conversion Date (or (x) in the Redemption Notice, if applicable or (y) in the case of any conversions occurring on
or after September 15, 2026, no later than the Close of Business on the Business Day immediately preceding September 15, 2026. If the Company does not timely elect a Settlement Method, the Company shall no longer have the right to elect
Cash Settlement or Physical Settlement with respect to any conversions on such Conversion Date or during such period, as the case may be, 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 deemed to be $1,000. If the Company elects Combination Settlement but does not timely notify converting Holders of the Specified Dollar Amount per $1,000 principal amount
of Notes, such Specified Dollar Amount will be deemed to be $1,000. 
 (ii) Settlement Amount. 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 Physical Settlement, the Company shall deliver to the converting Holder, in respect of each $1,000
principal amount of its Notes being converted, a number of shares of Common Stock equal to the applicable Conversion Rate in effect on the relevant Conversion Date, together with cash in lieu of delivering any fractional shares of Common Stock
pursuant to Section 4.03(b); 
 (B) if the Company elects (or is deemed to have elected) Cash Settlement, the Company
shall pay to the converting Holder, in respect of each $1,000 principal amount of its Notes being converted, cash in an amount equal to the sum of the Daily Conversion Values for each of the 40 consecutive VWAP Trading Days during the related
Observation Period; and 

  
 39 












 (C) if the Company elects (or is deemed to have elected) Combination
Settlement, the Company shall pay or deliver, as the case may be, to the converting Holder, in respect of each $1,000 principal amount of its Notes being converted, an amount of cash and number of shares of Common Stock, if any, equal to the sum of
the Daily Settlement Amounts for each of the 40 consecutive VWAP Trading Days during the related Observation Period. 
 (iii)
Delivery Obligation. The Company shall pay or deliver, as the case may be, the Settlement Amount due in respect of its conversion obligation under this Section 4.03, (x) on the second Business Day immediately following the relevant
Conversion Date, if the Company elects Physical Settlement and (y) on the second Business Day immediately following the last VWAP Trading Day of the related Observation Period, if the Company elects Cash Settlement or Combination Settlement.

 (b) Fractional Shares. Notwithstanding the foregoing, the Company will not issue fractional shares of Common Stock
as part of the Settlement Amount due with respect to any converted Note. Instead, if any Settlement Amount includes a fraction of a share of the Common Stock, the Company will, in lieu of delivering such fraction of a share of Common Stock, pay an
amount of cash equal to the product of such fraction of a share and (i) in a Physical Settlement, the Daily VWAP on the relevant Conversion Date, or if such Conversion Date is not a VWAP Trading Day, the immediately preceding VWAP Trading Day
or (ii) in a Combination Settlement, the Daily VWAP on the last VWAP Trading Day of the relevant Observation Period (subject to Section 4.03(c) immediately below). 

(c) Conversion of Multiple Notes by a Single Holder. If a Holder surrenders more than one Note for conversion on a
single Conversion Date or with respect to which a single Observation Period (including, for the avoidance of doubt, the same VWAP Trading Days therein) would apply, the Company will calculate the amount of cash and the number of shares of Common
Stock due with respect to such Notes as if such Holder had surrendered for conversion one Note having an aggregate principal amount equal to the sum of the principal amounts of each of the Notes surrendered for conversion by such Holder on the same
Conversion Date. 
 (d) Settlement of Accrued Interest and Deemed Payment of Principal. If a Holder converts a Note,
the Company will not adjust the Conversion Rate to account for any accrued and unpaid interest on such Note, and the Company’s delivery or payment, as the case may be, of cash, shares of Common Stock or a combination of cash and shares of
Common Stock into which a Note is convertible will be deemed to satisfy and discharge in full the Company’s obligation to pay the principal of, and accrued and unpaid interest, if any, on, such Note to, but excluding, the Conversion Date;
provided, however, that subject to Section 4.02(f), if a Holder converts a Note after the Close of Business on a Regular Record Date and prior to the Open of Business on the corresponding Interest Payment Date, the Company will
still be obligated to pay the interest due on such Interest Payment Date to the Holder of such Note on such Regular Record Date. 

  
 40 












 As a result, except as otherwise provided in the proviso to the immediately preceding
sentence, any accrued and unpaid interest with respect to a converted Note will be deemed to be paid in full rather than cancelled, extinguished or forfeited. In addition, if the Settlement Amount for any Note includes both cash and shares of the
Common Stock, accrued and unpaid interest will be deemed to be paid first out of the amount of cash delivered upon such conversion. 

(e) Notices. Whenever a Conversion Date occurs with respect to a Note, the Conversion Agent will, as promptly as
possible, and in no event later than the Open of Business on the Business Day immediately following such Conversion Date, deliver to the Company and the Trustee, if it is not then the Conversion Agent, notice that a Conversion Date has occurred,
which notice will state such Conversion Date, the principal amount of Notes converted on such Conversion Date and the names of the Holders that converted Notes on such Conversion Date. 

On the first Business Day immediately following the last VWAP Trading Day of the Observation Period applicable to any Note surrendered for
conversion in a Cash Settlement or a Combination Settlement, the Company will deliver a written notice to the Conversion Agent and the Trustee (if not also the Conversion Agent) stating the amount of cash and the number of shares of Common Stock, if
any, that the Company is obligated to pay or deliver, as the case may be, to satisfy its conversion obligation with respect to each Note converted on such Conversion Date. 

Section 4.04 Adjustment of Conversion Rate. The Conversion Rate will be adjusted as described in this Section 4.04, except
that the Company shall not make any adjustment to the Conversion Rate if Holders participate (other than in the case of a share split or share combination) at the same time and upon the same terms as holders of the Common Stock and as a result of
holding the Notes, in any of the transactions described below without having to convert their Notes, as if they held a number of shares of Common Stock equal to the applicable Conversion Rate, multiplied by the principal amount (expressed in
thousands) of Notes held by such Holder. 
 (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 will be adjusted based on the following formula: 
  


							
		 	CR1 = CR0 x	 	 OS1
	  	
		 	OS0	  	

 where, 
  

					
	      	 	CR0 =	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the Open of Business on the effective
date of such share split or combination, as applicable;
			
		 	CR1 =	  	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date or such 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 such effective date, as applicable (before giving effect to any such
dividend or distribution); and
			
		 	OS1 =	  	the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination, as applicable.


  
 41 












 Any adjustment made under this Section 4.04(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 4.04(a) is declared but not so paid or made, or any share split or combination of the type described in this Section 4.04(a) is announced but the outstanding shares of Common
Stock are not so split or combined, as applicable, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, or not to split or combine the outstanding
shares of Common Stock, as applicable, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared or such share split or combination had not been announced. 

(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 stockholders rights plan) entitling them, for a period of not more than 60 calendar days after the date of such issuance, to subscribe for or purchase shares of the Common Stock, at a price per share 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 will be increased based on the
following formula: 
  

							
		 	CR1 = CR0 x	  	 OS0 + X
	  	
		  	OS0 + Y	  	

  

					
	      	 	CR0 =	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such issuance;
			
		 	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.


  
 42 












 Any increase made under this Section 4.04(b) will 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 Common Stock are not delivered upon the expiration of such rights, options or warrants, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the increase
with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so issued, or if such rights, options or
warrants are not exercised prior to their expiration, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such issuance had not occurred. 

For purposes of this Section 4.04(b) and Section 4.01(b)(iii)(x) hereof, in determining whether any rights, options or warrants
entitle the holders of the Common Stock to subscribe for or purchase shares of the Common Stock at a price per share 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 the 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 thereof, the value of such consideration, if other than cash, to be determined by the Company in good faith and in a commercially reasonable manner. 

(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 or distributions, rights options or warrants described in Section 4.04(a) hereof or Section 4.04(b)
hereof; 
 (ii) dividends or distributions paid exclusively in cash as to which the provisions set forth in
Section 4.04(d) below shall apply; 
 (iii) except as otherwise described below, rights issued pursuant to a stockholder
rights plan of the Company; 
 (iv) Spin-Offs as to which the provisions set forth below in this Section 4.04(c) shall
apply; and 

  
 43 












 (v) dividends or distributions of Reference Property upon conversion of, or
exchange for, Common Stock pursuant to any Share Exchange Event (as defined below under Section 4.07); 
 (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 of the Company, the “Distributed Property”), then the Conversion Rate shall be increased based on
the following formula: 
  

					
	CR1 = CR0 x	  	 SP0
	  	
	  	SP0 - FMV	  	

  

			
	where,
		
	CR0 =	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such distribution;
		
	CR1 =	  	the Conversion Rate in effect immediately after the Open of Business on 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 Company in good faith and in a commercially reasonable manner) of Distributed Property with respect to each outstanding share of the Common Stock as of the Open of Business on the Ex-Dividend Date for such distribution.


 If “FMV” (as defined above) is equal to or greater than the “SP0” (as defined above), in lieu of the foregoing increase, each Holder of Notes shall receive, in respect of each $1,000 principal amount of Notes it holds, at the same time and upon the same
terms as holders of the Common Stock, the amount and kind of Distributed Property that such Holder would have received as if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect immediately prior to the record
date for the distribution. 
 Any increase made pursuant to the formula above will become effective immediately after the Open of Business on
the Ex-Dividend Date for such distribution. If such distribution (including a Spin-Off) is not so paid or made, the Conversion Rate shall be decreased to be the
Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 

  
 44 












 With respect to an adjustment pursuant to this Section 4.04(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 any Subsidiaries of the Company or business units of the Company, and such Capital Stock
or similar equity interest is listed or quoted (or will be listed or quoted upon the consummation of the distribution) on a U.S. national securities exchange (a “Spin-Off”), the Conversion
Rate will be increased based on the following formula: 
  

					
	CR1 = CR0 x	  	 FMV0 + MP0
	  	
	  	MP0	  	

 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 Common Stock applicable to one share of Common Stock (determined by reference to the definitions of “Last
Reported Sale Price,” “Trading Day” and “Market Disruption Event” as if references therein to the Common Stock were to such Capital Stock or similar equity interest) over the first ten consecutive Trading Day period after,
and including, the Ex-Dividend Date of the Spin-Off (the “Valuation Period”); provided that if there is no Last Reported Sale Price of the Capital Stock
or similar equity interest distributed to holders of the Common Stock on such Ex-Dividend Date, the “Valuation Period” shall be the first ten consecutive Trading Day period after, and
including, the first date such Last Reported Sale Price is available; and
		
	MP0 =	  	the average of the Last Reported Sale Prices of Common Stock over the Valuation Period.


 The increase to the Conversion Rate under the preceding paragraph will 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 to
“ten” in the preceding paragraph 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 VWAP Trading
Day that falls within the relevant Observation Period for such conversion and within the Valuation Period, the reference to “ten” in the preceding paragraph 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 VWAP Trading Day in determining the Conversion Rate as of such VWAP Trading Day. In addition, if the Ex-Dividend date for such Spin-Off is after the tenth Trading Day immediately preceding, and including, the end of any Observation Period in respect of a conversion of Notes,
references to “ten” or 

  
 45 












 
“tenth” in the preceding paragraph and this paragraph shall be deemed to be replaced, solely in respect of that conversion, with such lesser number of Trading Days as have elapsed from,
and including, the Ex-Dividend Date for such Spin-Off to, and including, the last VWAP Trading Day of such Observation Period. If the distribution constituting the Spin-Off is not so paid or made, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such distribution had not been declared. 

For purposes of the second adjustment formula set forth in this Section 4.04(c), (i) the Last Reported Sale Price of any Capital
Stock or similar equity interest shall be calculated in a manner analogous to that used to calculate the Last Reported Sale Price of the Common Stock in the definition of “Last Reported Sale Price” set forth in Section 1.01 hereof,
(ii) whether a day is a Trading Day (and whether a day is a Scheduled Trading Day and whether a Market Disruption Event has occurred) for such Capital Stock or similar equity interest shall be determined in a manner analogous to that used to
determine whether a day is a Trading Day (or whether a day is a Scheduled Trading Day and whether a Market Disruption Event has occurred) for the Common Stock, and (iii) whether a day is a Trading Day to be included in a Valuation Period will
be determined based on whether a day is a Trading Day for both the Common Stock and such Capital Stock or similar equity interest. 

(d) If any cash dividend or distribution is made to all holders of the Common Stock, excluding any consideration payable in
connection with a Tender Offer or exchange offer made by the Company or any of its Subsidiaries, the Conversion Rate shall be adjusted based on the following formula: 
  

					
	CR1 = CR0 x	  	 SP0
	  	
	  	SP0 - C	  	

 where, 
  

			
	CR0 =	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such 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 of Common Stock that the Company distributes to holders of the Common Stock.


 Any increases made under this Section 4.04(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 Company’s Board of
Directors determines not to make or pay such 

  
 46 












 
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 shall receive, for each $1,000 principal amount of Notes it holds,
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 had owned a number of shares of Common Stock equal to the Conversion Rate in effect immediately
prior to the record date for such cash dividend or distribution. 
 (e) If the Company or any of its Subsidiaries make a
payment in respect of a tender offer or exchange offer for the Common Stock (other than Odd Lot Tender Offers), to the extent that the cash and value of any other consideration included in the payment per share of the Common Stock exceeds the Last
Reported Sale Price of the Common Stock on the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer (the “Offer Expiration Date”), the Conversion Rate shall be
increased based on the following formula: 
  

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

 where, 
  

			
		
	CR0 =	  	the Conversion Rate in effect immediately prior to the Close of Business on the Offer Expiration Date;
		
	CR1 =	  	the Conversion Rate in effect immediately after the Close of Business on the Offer Expiration Date;
		
	AC =	  	the aggregate value of all cash and any other consideration (as determined by the Company in good faith and in a commercially reasonable manner) paid or payable for shares of Common Stock purchased in such tender or exchange
offer;
		
	OS0 =	  	the number of shares of Common Stock outstanding immediately prior to the expiration time of the tender or exchange offer on the Offer Expiration Date (prior to giving effect to the purchase of all shares accepted for purchase or
exchange in such tender or exchange offer);
		
	OS1 =	  	the number of shares of Common Stock outstanding immediately after the expiration time of the tender or exchange offer on the Offer Expiration Date (after giving effect to the purchase of all shares accepted for purchase or exchange
in such tender or exchange offer); and
		
	SP1 =	  	the Last Reported Sale Price of the Common Stock on the Trading Day next succeeding the Offer Expiration Date.

 (f) Special Settlement Provisions. 

In addition, notwithstanding anything to the contrary herein, if a Conversion Rate adjustment for any event becomes effective
on any Ex-Dividend Date as described in Sections 4.04(a) through (e) hereof, and a Holder that has converted its Notes with a Conversion Date occurring on or after such
Ex-Dividend Date and on or prior to the related record date would be treated as the record holder of shares of Common Stock as of the related Conversion Date as described under Section 4.02 hereof based
on an adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding the foregoing Conversion Rate adjustment provisions, the Conversion Rate adjustment relating to such Ex-Dividend Date will not be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the registered owner of the shares of Common Stock on an unadjusted basis and participated
in the related dividend, distribution or other event giving rise to such adjustment. 
 In addition, notwithstanding anything
to the contrary herein, if, in the case of any conversion of a Note to which Combination Settlement applies, on any VWAP Trading Day during the Observation Period corresponding to the Conversion Date for such Note, shares of Common Stock are
deliverable as part of the Daily Settlement Amount for such VWAP Trading Day, and 
 (i) the record date for any issuance,
dividend or distribution, the effective date for any share split or combination or the Offer Expiration Date for any tender or exchange offer by the Company or its Subsidiaries that, in each case, would require an adjustment to the Conversion Rate
pursuant to any of Section 4.04(a) through (e) occurs prior to the Company’s delivery of such shares of Common Stock to the converting Holder; 

(ii) the applicable Conversion Rate for such VWAP Trading Day will not reflect such adjustment; and 

(iii) the shares of Common Stock that the Company shall deliver to the converting Holder with respect to such VWAP Trading Day
are not entitled to participate in the relevant event (because such shares were not held by such Holder on the related record date, effective date, Offer Expiration Date or otherwise), 

then the Company will (i) in the case of any such issuance, dividend or distribution, deliver to the Holder of such Note, on the date on
which such issuance, dividend or distribution is paid or made, the consideration that a Holder of a number of shares equal to the number of shares included in the Daily Settlement Amount for such VWAP Trading Day would be entitled to receive in
respect of such issuance, dividend or distribution or (ii) in the case of any such share split or combination, tender offer or exchange offer, adjust the number of shares that the Company delivers to such Holder as part of the Daily Settlement
Amount for such VWAP Trading Day in a manner that appropriately (as determined by the Company in consultation with a nationally recognized independent investment banking firm, which may be the Initial Purchaser, retained for this purpose) reflects
the relevant transaction or event. 

  
 48 












 (g) Poison Pill. If a Holder converts a Note, to the extent that the
Company has a rights plan in effect at such time, if Physical Settlement applies to such Note, on the Conversion Date applicable to such Note, and if Combination Settlement applies to such Note on any VWAP Trading Day in the Observation Period
applicable to such Note, the Holder converting such Note will receive, in addition to any shares of Common Stock otherwise received in connection with such conversion on such Conversion Date or such VWAP Trading Day, as the case may be, the rights
under the rights plan, unless prior to such Conversion Date or such VWAP Trading Day, as the case may be, the rights have separated from the Common Stock, in which case, and only in such case, the Conversion Rate will be adjusted at the time of
separation as if the Company distributed to all holders of the Common Stock, Distributed Property as described in Section 4.04(c) hereof, subject to readjustment in the event of the expiration, termination or redemption of such rights. 

(h) Deferral of Adjustments. No adjustment to the Conversion Rate will be required unless the adjustment would require
an increase or decrease of at least 1% of the Conversion Rate and such adjustment would otherwise have been made prior to the Effective Date of any Share Exchange event in respect of which the Common Stock is replaced by Reference Property
consisting solely of cash; provided, however, that if an adjustment is not made because the adjustment does not change the Conversion Rate by at least 1%, then such adjustment will be carried forward, except that all such 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) in the case of any Note to which Physical
Settlement applies prior to the Close of Business on the Conversion Date, (iii) in the case of the replacement of the Common Stock by Reference Property consisting solely of cash, on the Effective Date of the Share Exchange Event relating to
such replacement, (iv) in the case of any Note to which Cash Settlement or Combination Settlement applies (other than as described in the immediately preceding clause (iii)), prior to the Open of Business on the first VWAP Trading Day of the
applicable Observation Period and each subsequent VWAP Trading Day of the Observation Period; (v) prior to the Close of Business on any other date on which the Conversion Rate is referred to for purpose of determining the consideration
deliverable upon settlement of a Note; (vi) on the Effective Date of any Fundamental Change or Make-Whole Fundamental Change; (vii) the Redemption Date; and (vii) September 15, 2026. In addition, the Company shall not account for
such deferrals when determining whether any of the conditions to conversion have been satisfied or what number of shares of Common Stock a Holder would have held on a given day had it converted its Notes. 

(i) Limitation on Adjustments. Except as stated in this Section 4.04, the Company will not adjust the Conversion
Rate for the issuance of shares of Common Stock or any securities convertible into or exchangeable for shares of Common Stock or the right to purchase shares of Common Stock or such convertible or exchangeable securities. If, however, the
application of the formulas in Sections 4.04(a) through (e) hereof would result in a decrease in the Conversion Rate, then, except to the extent of any readjustment to the Conversion Rate, no adjustment to the Conversion Rate will be made
(other than as a result of a reverse share split or share combination). 

  
 49 












 (j) For purposes of this Section 4.04, the number of shares of Common
Stock at any time outstanding shall not include shares held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include
shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. 
 (k) Except as
provided for in this Section 4.04 and in Section 4.06 below, the Conversion Rate will not be required to be adjusted for any transaction or event. Without limiting the foregoing, the Conversion Rate will not be required to be adjusted:

 (i) except as described in this Section 4.04, upon the issuance of Common Stock for cash at a price below the Conversion Price or
otherwise; 
 (ii) 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 the Common Stock under any plan; 

(iii) 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 its subsidiaries; 
 (iv) upon the issuance of any
shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in the preceding subclause (iii) and outstanding as of the date of the initial issuance of the Notes; 

(v) upon the repurchase of any shares of Common Stock pursuant to an open-market share repurchase program or other buy-back transaction (including, without limitation, through any structured or derivative transaction such as accelerated share repurchase derivative or similar forward derivative) that is not a tender offer or
exchange offer of the nature described under Subsection 4.04(e) above; 
 (vi) as a result of a Tender Offer solely to holders of fewer than
100 shares of Common Stock (an “Odd Lot Tender Offer”); 
 (vii) for a third-party Tender Offer by any party other than a
Tender Offer by one or more of the Company’s Subsidiaries as described in Subsection 4.04(e) above; 
 (viii) solely for a change in the
par value of the Common Stock; or 
 (ix) for accrued and unpaid Interest, if any. 

  
 50 












 Section 4.05 Discretionary and Voluntary Adjustments. 

(a) Discretionary Adjustments. Whenever any provision of this Indenture requires the Company to calculate the Trading
Prices, the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts or any function thereof over a span of multiple days, Trading Days or VWAP Trading Days (including during an Observation Period), the
Company will make appropriate adjustments to each such calculation to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the effective date, Ex-Dividend Date or Offer Expiration Date of the event occurs, at any time during the period when such Trading Price, Last Reported Sale Price, Daily VWAP, Daily Conversion Value or Daily Settlement Amount or
function thereof is to be calculated. For the avoidance of doubt, the adjustments made pursuant to this paragraph will be made without duplication of any adjustment made pursuant to the provisions set forth under Section 4.04. 

(b) Voluntary Adjustments. To the extent permitted by applicable law and applicable requirements of The NASDAQ Global
Select Market, the Company is permitted (but not required) to increase the Conversion Rate of the Notes (i) 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 or (ii) to avoid or diminish income tax to holders of Common Stock or rights to purchase shares of Common Stock in connection with a dividend or distribution of shares (or rights to acquire shares) or similar event.

 Section 4.06 Adjustment to Conversion Rate Upon Conversion in Connection with a Make-Whole Fundamental Change or Notice of Optional
Redemption. 
 (a) Increase in the Conversion Rate. If (i) the Effective Date of a Make-Whole Fundamental
Change occurs prior to the Maturity Date or (ii) the Company issues a Redemption Notice and, in each case, a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change or Redemption Notice, as applicable, then the
Company shall, to the extent provided herein, 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 in this
Section 4.06. A conversion of Notes shall be deemed for these purposes to be “in connection with” (x) a Make-Whole Fundamental Change if the relevant Conversion Notice is received by the Conversion Agent during the period from, and
including, the Effective Date of the Make-Whole Fundamental Change up to, and including, the Close of Business on the Business Day immediately prior to the related Fundamental Change Repurchase Date or, if such Make-Whole Fundamental Change is not
also a Fundamental Change, the 35th Business Day immediately following the Effective Date for such Make-Whole Fundamental Change (such period, the “Make-Whole Fundamental Change Period”) or (y) a Redemption Notice if the
applicable Conversion Date occurs during the period from, and including, the date of the Redemption Notice until the Close of Business on the second Business Day immediately preceding the related Redemption Date and, in the case of any partial
redemption, such Notes have been called for Optional Redemption (or deemed to be called pursuant to Section 11.07). Notwithstanding anything to the contrary in this Section 4.06(a), if the Conversion Date for the conversion of a Note
occurs “in 

  
 51 












 
connection with” both a Make-Whole Fundamental Change and a Redemption Notice, then, solely for purposes of such conversion, (x) such Conversion Date will be deemed to occur solely
“in connection with” the earlier of the Effective Date of such Make-Whole Fundamental Change and the date of such Redemption Notice; and (y) such later date will be deemed not to have occurred. 

(b) Cash Mergers. Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change or
Redemption Notice, the Company will, at its option, satisfy its conversion obligation by Physical Settlement, Cash Settlement or Combination Settlement, based on the Conversion Rate as increased to reflect the Additional Shares pursuant to the table
attached as Schedule A hereto, as described in Section 4.03. However, if the if the consideration paid to holders of the Common Stock in any Make-Whole Fundamental Change described in clause (2) of the definition
of “Fundamental Change” is comprised entirely of cash, then, for any conversion of Notes following the Effective Date of such Make-Whole Fundamental Change, the payment and delivery obligations upon the conversion of each $1,000 principal
amount of Notes shall be calculated based solely on the Stock Price (determined in the manner described in Section 4.06(c)) for such Make-Whole Fundamental Change and shall be deemed to be an amount of cash per $1,000 principal amount of
converted Notes equal to the applicable Conversion Rate (including any adjustment as described in this Section 4.06) multiplied by such Stock Price. In such event, the Company’s conversion obligation will be determined and paid to
Holders in cash on the second Business Day following the applicable Conversion Date. Otherwise, the Company will settle any conversion of the Notes following the Effective Date for a Make-Whole Fundamental Change in accordance with Section 4.03
hereof (but subject to Section 4.04 hereof). 
 (c) Determining the Number of Additional Shares. The number of
Additional Shares, if any, by which the Conversion Rate will be increased for a Holder that converts its Notes in connection with a Make-Whole Fundamental Change or Redemption Notice, as applicable, shall be determined by reference to the table
attached as Schedule A hereto, based on the Effective Date of the Make-Whole Fundamental Change or the date of the Redemption Notice, as applicable, and the price paid (or deemed to be paid) per share of the Common Stock in
the Make-Whole Fundamental Change or with respect to the Redemption Notice, as the case may be (the “Stock Price”). If the holders of the Common Stock receive only cash in a Make-Whole Fundamental Change described in clause (2)
of the definition of “Fundamental Change,” the Stock Price shall be the cash amount paid per share of Common Stock. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the five
consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change or the date of the Redemption Notice, as applicable. For the avoidance of doubt, if the Company
elects to redeem less than all of the Outstanding Notes, then Holders of the Notes not called for redemption will not be entitled to an increased Conversion Rate for such Notes as described in this Section 4.06 on account of such redemption,
except to the limited extent described in Section 11.07. 

  
 52 












 (d) Interpolation and Limits. The exact Stock Price and Effective
Date may not be set forth in the table in Schedule A in which case: 
 (i) If the Stock Price is
between two Stock Prices in the table or the Effective Date is between two effective dates in the table, the number of Additional Shares by which the Conversion Rate will be increased shall be determined by a straight-line interpolation between the
number of Additional Shares set forth for the higher and lower Stock Prices and the earlier and later effective dates, as applicable, based on a 365 year. 

(ii) If the Stock Price is greater than $400.00 per share (subject to adjustment in the same manner as the Stock Prices set
forth in the column headings of the table in Schedule A hereof), no Additional Shares will be added to the Conversion Rate. 

(iii) If the Stock Price is less than $69.68 per share (subject to adjustments in the same manner as the Stock Prices set forth
in the column headings of the table in Schedule A hereof), no Additional Shares will be added to the Conversion Rate. 

Notwithstanding the foregoing, in no event will the Conversion Rate be increased on account of a Make-Whole Fundamental Change or a Redemption
Notice to exceed 14.3513 shares of Common Stock per $1,000 principal amount of Notes, subject to adjustments in the same manner as the Conversion Rate is required to be adjusted as set forth in Section 4.04 hereof. 

(iv) The Stock Prices set forth in the column headings of the table in Schedule A hereto shall be
adjusted as of any date on which the Conversion Rate of the Notes is otherwise required to be adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the
numerator of which is the Conversion Rate immediately prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in such table
shall be adjusted in the same manner and at the same time as the Conversion Rate is required to be adjusted as set forth in Section 4.04. 

(e) Notices. The Company shall notify in writing the Holders, the Trustee and the Conversion Agent (if other than the
Trustee) of the Effective Date of any Make-Whole Fundamental Change in accordance Section 4.01(b)(iv) (or, if such Effective Date is on or after September 15, 2026, no later than such actual Effective Date) or in accordance with Article
11, as applicable. 

  
 53 












 Section 4.07 Effect of Recapitalization, Reclassification, Consolidation, Merger or Sale. 

(a) Share Exchange Events. In the case of: 

(i) any recapitalization, reclassification or change of Common Stock (other than a change to par value or from par value to no
par value or other than changes resulting from a subdivision or combination); 
 (ii) any consolidation, merger, combination
or similar transaction involving the Company; 
 (iii) any sale, lease or other transfer to a third party of all or
substantially all of the consolidated assets of the Company and its Subsidiaries, 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, or represent solely the
right to receive, stock, other securities or other property or assets (including cash or any combination thereof) (any such event, a “Share Exchange Event” and any such stock, other securities or other property or assets,
“Reference Property,” and the amount of Reference Property that a holder of one share of Common Stock immediately prior to such Share Exchange Event would have been entitled to receive upon the occurrence of such Share Exchange
Event, a “Reference Property Unit”), then the Company or the successor or purchasing company, as the case may be, shall execute with the Trustee a supplemental indenture providing that, at and after the effective time of such Share
Exchange Event, the consideration due upon conversion of any Notes, and the conditions to any such conversion, will be determined in the same manner as if each reference to any number of shares of Common Stock in this Article 4 were instead a
reference to the same number of Reference Property Units. 
 If a Share Exchange Event causes the Common Stock to be
converted into, or exchanged for, or represent solely 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 shall be deemed to be the
weighted average of the types and amounts of consideration actually received by holders of Common Stock), and (ii) the Reference Property Unit for purposes of the immediately preceding paragraph shall refer to the consideration referred to in
clause (i) attributable to one share of Common Stock. 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.
Notwithstanding anything to the contrary herein, if the Reference Property Unit consists entirely of cash, then the Company will be deemed to elect Cash Settlement in respect of all conversions whose Conversion Date occurs after the effective date
of the Share Exchange Event described above, and the Company will pay the cash due upon such conversions no later than the second Business Day after the Conversion Date. For these purposes, the Daily VWAP or Last Reported Sale Price of any Reference
Property Unit or portion thereof that does not consist of a class of securities will be the fair value of such Reference Property unit or portion thereof, as applicable, determined in good faith by the Company (or, in the case of cash denominated in
U.S. dollars, the face amount thereof). 

  
 54 












 Such supplemental indenture described in the second immediately preceding
paragraph shall provide, to the extent the Reference Property is comprised, in whole or in part, of Common Equity, for anti-dilution and other adjustments that are as nearly equivalent as possible to the adjustments provided for in this Article 4.
If the Reference Property in respect of any Share Exchange Event includes shares of stock, securities or other property or assets of a Person other than the Company or, in the case of a transaction described in Article 9, the Successor Company, then
such supplemental indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders of Notes, including the right of Holders to require the Company to repurchase their Notes
upon a Fundamental Change pursuant to Article 3, as the Company shall reasonably consider necessary by reason of the foregoing. 

(b) If the Company executes a supplemental indenture pursuant to this Section 4.07, as promptly as practicable, the
Company shall file with the Trustee an Officer’s Certificate briefly describing such Share Exchange Event, the composition of a Reference Property Unit for such Share Exchange Event, any adjustment to be made with respect thereto and that all
conditions precedent to such Share Exchange Event under this Indenture have been complied with. Any failure to deliver such Officer’s Certificate shall not affect the legality or validity of such supplemental indenture. The Company shall also
issue a press release containing such information or shall make such information available on its website. 
 (c) The Company
shall not become a party to any Share Exchange Event unless its terms are consistent with this Section 4.07. None of the foregoing provisions shall affect the right of a Holder of Notes to convert its Notes as set forth in Section 4.01 and
Section 4.02 prior to the effective date of such Share Exchange Event. 
 (d) The provisions of this Section 4.07
shall apply successively to successive Share Exchange Events. 
 Section 4.08 Certain Covenants. 

(a) Reservation of Shares. To the extent necessary to satisfy its obligations under this Indenture, prior to issuing any
shares of Common Stock, the Company will reserve out of its authorized but unissued shares of Common Stock a sufficient number of shares of Common Stock to permit the conversion of the Notes, assuming Physical Settlement applies to all Notes. 

(b) Certain other Covenants. The Company covenants that all shares of Common Stock issued upon conversion of Notes shall
be issued in book-entry format if and to the extent that the Common Stock is eligible to trade in book-entry format through the facilities of the DTC, shall be newly issued shares or treasury shares, shall be duly authorized, validly issued, fully
paid and non-assessable and shall be free from preemptive rights and free from any tax, lien or charge (other than those created by the Holder or due to a change in registered owner). The Company shall list or
cause to have quoted any shares of Common Stock to be issued upon conversion of Notes on the 

  
 55 












 
NASDAQ Global Select Market to the extent that the Common Stock is then listed or quoted on the NASDAQ Global Select Market (or, if the Common Stock is not then listed on The NASDAQ Global Select
Market, the Company shall use its commercially reasonable efforts to list or cause to have quoted any shares of Common Stock to be issued upon conversion of Notes on each national securities exchange or over-the-counter or other domestic market (each, an “Exchange”) on which the Common Stock is then listed or quoted), in each case if permitted and required by the rules of the NASDAQ Global Select
Market or such Exchange. 
 Section 4.09 Responsibility of Trustee. The Trustee and any Conversion Agent shall not at any time be under any duty
or responsibility to any Holder of Notes to determine or calculate the Conversion Rate, to determine whether any facts exist which may require any adjustment of the Conversion Rate, or to confirm the accuracy of any such adjustment when made or the
appropriateness of the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or
amount) of any shares of Common Stock or of any other securities or property that may at any time be issued or delivered upon the conversion of any Notes; and the Trustee and the 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 Notes for the
purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 4. The rights, privileges, protections, immunities and benefits given to the Trustee, including without limitation its
right to be compensated, reimbursed and indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, including its capacity as Conversion Agent and as Bid Solicitation Agent (if applicable). 

Section 4.10 Notice of Adjustment to the Trustee. Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly
(i) file with the Trustee and any Conversion Agent (if other than 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;
provided that 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 that the last
Conversion Rate of which it has knowledge is still in effect and (ii) deliver written notice to the Holders, at his or her last address appearing on the Register provided for in Section 2.06 of this Indenture, stating that such adjustment
has become effective and the Conversion Rate or conversion privilege as adjusted. Failure to deliver such notice shall not affect the legality, effectiveness or validity of any such adjustment and shall not be an Event of Default under this
Indenture. 

  
 56 












 Section 4.11 Notice to Holders. 

(a) Notice to Holders Prior to Certain Actions. The Company shall deliver written notices of the events specified below
at the times specified below and containing the information specified below unless, in each case (i) pursuant to this Indenture, the Company is already required to deliver notice of such event containing at least the information specified below
at an earlier time or (ii) the Company, at the time it is required to deliver a notice, does not have knowledge of all of the information required to be included in such notice, in which case, the Company shall (A) deliver notice at such
time containing only the information that it has knowledge of at such time (if it has knowledge of any such information at such time), and (B) promptly upon obtaining knowledge of any such information not already included in a notice delivered
by the Company, deliver notice to each Holder containing such information. In each case, the failure by the Company to give such notice, or any defect therein, shall not affect the legality or validity of such event. 

(i) Issuances, Distributions, and Dividends and Distributions. If the Company (A) announces any issuance of any
rights, options or warrants that would require an adjustment in the Conversion Rate pursuant to Section 4.04(b) hereof; (B) authorizes any distribution that would require an adjustment in the Conversion Rate pursuant to
Section 4.04(c) hereof (including any separation of rights from the Common Stock described in Section 4.04(g) hereof); or (C) announces any dividend or distribution that would require an adjustment in the Conversion Rate pursuant to
Section 4.04(d) hereof, then the Company shall deliver to the Holders, as promptly as practicable after the holders of the Common Stock are notified of such event, notice describing such issuance, dividend or distribution, as the case may be,
and stating the expected Ex-Dividend Date and record date for such issuance, dividend or distribution, as the case may be. 

(ii) Tender and Exchange Offers. If the Company announces any tender or exchange offer that could require an adjustment
in the Conversion Rate pursuant to Section 4.04(e) hereof, the Company shall deliver to the Holders within three Business Days following the day it announces such tender or exchange offer, and, if the Company is required to file with the
Commission a Schedule TO in connection with such tender or exchange offer, an additional written notice (i) when the Company first files such Schedule TO, which notice shall include the address at which such Schedule TO is available on the
Commission’s EDGAR system (or any successor thereto), and (ii) whenever the Company files an amendment to such Schedule TO, which notice shall include the address at which such amendment is available on the Commission’s EDGAR system
(or any successor thereto). 
 (iii) Voluntary Increases. If the Company increases the Conversion Rate pursuant to
Section 4.05(b), the Company shall deliver notice to the Holders prior to the date on which such increase will become effective, which notice shall state the date on which such increase will become effective and the amount by which the
Conversion Rate will be increased. 
 (iv) Dissolutions, Liquidations and
Winding-Ups. If there is a voluntary or involuntary dissolution, liquidation or winding-up of the Company, the Company shall deliver notice to the Holders at
promptly as possible, but in any event prior to the earlier of (i) the date on which such dissolution, liquidation or winding-up, as the case may be, is expected to become effective or occur, and


  
 57 












 
(ii) the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such
dissolution, liquidation or winding-up, as the case may be, which notice shall state the expected effective date and record date for such event, as applicable, and the amount and kind of property that a holder
of one share of the Common Stock is expected to be entitled, or may elect, to receive in such event. The Company shall deliver an additional written notice to Holders, as promptly as practicable, whenever the expected effective date or record date,
as applicable, or the amount and kind of property that a holder of one share of the Common Stock is expect to be entitled to receive in such event, changes. 

For the avoidance of doubt, no failure to comply with this Section 4.11 shall be an Event of Default unless the
60-day period provided for in Section 6.01(f) has run and such Event of Default shall not have been cured prior to the expiration of such 60-day period. 

Section 4.12 Exchange in Lieu of Conversion.  

(a) Notwithstanding any other provision of this Article 4, when a Holder surrenders a Note for conversion, and the Conversion
Date for such Note occurs prior to September 15, 2026, the Company may, at its election, direct the Conversion Agent in writing to surrender, on or prior to the Scheduled Trading Day immediately preceding the first VWAP Trading Day of the
applicable Observation Period (or if the Company has elected Physical Settlement, on or prior to the second Business Day immediately following the relevant 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 pay and/or deliver, as the case may be, in exchange for such Notes, all of the cash, shares of Common
Stock or a combination thereof due upon conversion, all in accordance with Section 4.02. By the Close of Business on the Scheduled Trading Day immediately preceding the first VWAP Trading Day of the applicable Observation Period (or, if the
Company has elected Physical Settlement, by the Close of Business on the second Business Day immediately following the relevant Conversion Date), the Company shall notify in writing the Trustee, the Conversion Agent (if other than the Trustee) and
the Holder surrendering Notes for conversion that the Company has directed the designated financial institution to make an exchange in lieu of conversion. 

(b) If the designated financial institution accepts any such Notes, it will pay and/or deliver, as the case may be, the cash,
shares of Common Stock or a combination thereof due upon conversion to the Conversion Agent, and the Conversion Agent shall pay and/or deliver such cash, shares of Common Stock (and cash in lieu of fractional shares) or combination thereof to such
Holder on the second Business Day immediately following the last VWAP Trading Day of the applicable Observation Period (or, if the Company has elected Physical Settlement, on the second Business Day immediately following the relevant Conversion
Date). Any Notes exchanged by the designated financial institution will remain Outstanding subject to the Applicable Procedures. If the designated financial institution agrees to accept any Notes for exchange but does not timely pay and/or deliver
the related cash, shares of Common Stock or a combination 

  
 58 












 
thereof, as the case may be, or if such designated financial institution does not accept the Notes for exchange, the Company shall convert the Notes and pay and/or deliver, as the case may be,
the cash, shares or Common Stock or a combination thereof due upon conversion on the second Business Day immediately following the last VWAP Trading Day of the applicable Observation Period (or, if the Company has elected Physical Settlement, on the
second Business Day immediately following the relevant Conversion Date) as set forth in Section 4.02. The Company’s designation of a financial institution to which the 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 to do so). The Company may, but will not be obligated to, enter into a separate agreement with any designated financial institution
that would compensate it for any such transaction. 
 ARTICLE 5. 

COVENANTS 
 Section 5.01 Payment of
Principal, Interest, Redemption Price and Fundamental Change Repurchase Price . 
 The Company covenants and agrees that it will
cause to be paid the principal of (including the Fundamental Change Repurchase Price and Redemption Price, as applicable) and accrued and unpaid interest, if any, on each of the Notes at the places, at the respective times and in the manner provided
herein and in the Notes. 
 Section 5.02 Maintenance of Office or Agency. 

The Company will maintain in the continental United States an office of the Paying Agent, an office of the Registrar and an office or agency
where Notes may be surrendered for conversion (“Conversion Agent”) and where notices and demands to or upon the Company in respect of the Notes and this 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 office or agency. 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 or served at the Corporate Trust Office; provided that, the Corporate Trust Office shall not be an office or agency of the Company for purposes of legal process against the Company. 

The Company may also from time to time designate as co-Registrars one or more other offices or
agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided that no such designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in the continental United States for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other
office or agency. The terms “Paying Agent” and “Conversion Agent” include any such additional or other offices or agencies, as applicable. 

  
 59 












 The Company hereby initially designates the Trustee as the Paying Agent, Registrar,
Custodian and Conversion Agent, and its Corporate Trust Office, which shall be in the continental United States, shall be considered as one such office or agency of the Company for each of the aforesaid purposes. The Company may, however, change the
Paying Agent or Registrar without notice to the Holders. The Company or its Affiliates may act as Paying Agent or Registrar. 
 With respect
to any Global Note, the Corporate Trust Office of the Trustee or any Paying Agent shall be the place of payment where such Global Note may be presented or surrendered for payment or conversion or for registration of transfer or exchange, or where
successor Notes may be delivered in exchange therefor; provided, however, that any such payment, conversion, presentation, surrender or delivery effected pursuant to the Applicable Procedures for such Global Note shall be deemed to
have been effected at the place of payment for such Global Note in accordance with the provisions of this Indenture. 
 Section 5.03 Provisions as
to Paying Agent. 
 (a) If the Company shall appoint a Paying Agent other than the Trustee, the Company will cause such
Paying Agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 5.03: 

(i) that it will hold all sums held by it as such agent for the payment of the principal of, accrued and unpaid interest, if
any, on, or any Fundamental Change Repurchase Price or Redemption Price for, the Notes held in trust for the benefit of the Holders of the Notes; 

(ii) that it will give the Trustee prompt written notice of any failure by the Company to make any payment of the principal,
accrued and unpaid interest, if any, on, or any Fundamental Change Repurchase Price or Redemption Price for, the Notes when the same shall be due and payable; and 

(iii) that at any time during the continuance of an Event of Default, upon request of the Trustee, it will forthwith pay to the
Trustee all sums so held in trust. 
 The Company shall, on or before each due date of the principal of, accrued and unpaid interest, if
any, on, or any Fundamental Change Repurchase Price or Redemption Price for, the Notes, deposit with the Paying Agent a sum sufficient to pay such principal, accrued and unpaid interest, or any Fundamental Change Repurchase Price or Redemption Price
and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee in writing 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. 

  
 60 












 (b) If the Company shall act as its own Paying Agent, it will, on or before
each due date of the principal of, accrued and unpaid interest, if any, on, or any Fundamental Change Repurchase Price or Redemption Price for, the Notes, set aside, segregate and hold in trust for the benefit of the Holders of the Notes a sum
sufficient to pay such amount 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 such payment when the same shall become due and payable. Upon any
bankruptcy, reorganization or similar proceeding with respect to the Company, the Trustee shall automatically serve as Paying Agent for the Notes. 

(c) Anything in this Section 5.03 to the contrary notwithstanding, the Company may, at any time, for the purpose of
obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay or cause to be paid to the Trustee all sums held in trust by the Company or any Paying Agent hereunder as required by this Section 5.04, such sums to be held
by the Trustee upon the trusts herein contained and upon such payment by the Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released from all further liability with respect to such sums. 

(d) Subject to applicable abandoned property laws, any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of, accrued and unpaid interest, if any, on, or any Fundamental Change Repurchase Price or Redemption Price for, any Note and remaining unclaimed for two years after such principal, accrued and
unpaid interest, or any Fundamental Change Repurchase Price or Redemption Price 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 or such Paying Agent with respect to such trust money, and all
liability of the Company as trustee thereof, shall thereupon cease; provided, however, that before the Trustee or such Paying Agent are required to make any such repayment, the Company shall cause to be published once, in a newspaper
published in the English language, customarily published on each Business Day and of general circulation in The Borough of Manhattan, The City of New York, New York, notice that such money remains unclaimed and that, after a date specified therein,
which shall not be less than 30 calendar days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Company. 

Section 5.04 Reports. 

(a) The Company will file with the Trustee and the Holders, within 15 calendar days after it is required to file the same with
the Commission (giving effect to any grace period provided by Rule 12b-25 under the Exchange Act or any similar or successor grace period), copies of the quarterly and annual reports and of the information,
documents and other reports, if any, that it is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act. Any such report, information or document that the Company files with the Commission through the EDGAR
system (or any successor thereto) will be deemed to be delivered to the Trustee and the Holders for the purposes of this Section 5.04 at the time of such filing through the EDGAR system (or such successor thereto); provided, however,
that the Trustee shall have no responsibility to determine whether such filings have been made. Notwithstanding anything to the contrary herein, the Company shall in no event be required to file with, or otherwise provide or disclose to, the Trustee
or any Holder any information for which the Company is requesting (assuming such request has not been denied), or has received, confidential treatment from the SEC. 

  
 61 












 (b) Delivery of any such reports, information and documents to the Trustee
shall be for informational purposes only, and the Trustee’s receipt of such reports, information and documents shall not constitute constructive notice of any information contained therein or determinable from information contained therein,
including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely conclusively on Officer’s Certificates). 

(c) At any time the Company is not subject to Section 13 or 15(d) of the Exchange Act, the Company will, so long as any of
the Notes or the shares of Common Stock delivered upon conversion of the Notes will, at such time, constitute “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, promptly provide to the Trustee and will,
upon written request, provide to any Holder, beneficial owner or prospective purchaser of such Notes or such shares of Common Stock the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the
resale of such Notes or such shares of Common Stock pursuant to Rule 144A under the Securities Act. The Company will take such further action as any Holder or beneficial owner of such Notes or such shares of Common Stock may reasonably request from
time to time to enable such Holder or beneficial owner to sell such Notes or such shares of Common Stock in accordance with Rule 144A under the Securities Act, as such rule may be amended from time to time. 

Section 5.05 Statements as to Defaults. The Company is required to deliver to the Trustee, within 120 days after the end of each fiscal year, an
Officer’s Certificate, stating whether or not to the knowledge of the signer thereof the Company is in default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of
grace or requirement of notice provided under this Indenture) and, if the Company is in default, specifying all such Default or Event of Defaults and the nature and the status thereof of which he or she may have knowledge. In addition, the Company
shall deliver to the Trustee, as soon as possible, and in any event within 30 calendar days after the Company becomes aware of the occurrence of any Default or Event of Default, an Officer’s Certificate setting forth the details of such Default
or Event of Default, its status and the action that the Company proposes to take with respect thereto; provided that no such Officer’s Certificate shall be required to the extent that the event that would constitute a Default or Event of
Default has been cured or waived prior to the date on which such Officer’s Certificate is due.    Such Officer’s Certificate shall also comply with any additional requirements set forth in Section 5.07 hereof. The
Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof. 

Section 5.06 Additional Interest Notice. If Additional Interest is payable by the Company pursuant to Section 5.08 hereof or
Section 6.03 hereof, the Company shall deliver to the Trustee an Officer’s Certificate, prior to the Regular Record Date for each applicable Interest Payment Date, to that effect stating (a) the amount of such Additional Interest that
is payable and (b) the date on which such interest is payable. Unless and until a Responsible Officer of the Trustee 

  
 62 












 
receives at the Corporate Trust Office such a certificate, the Trustee may assume without inquiry that no such Additional Interest is payable. If the Company has paid Additional Interest directly
to the Persons entitled to it, the Company shall deliver to the Trustee an Officer’s Certificate setting forth the particulars of such payment. The Company shall also provide to all Holders of the Notes, the Trustee and the Paying Agent (in the
case of any Paying Agent other than the Trustee) a written notice stating (a) that Additional Interest is payable, (b) the amount of such Additional Interest that is payable and (c) the date on which such interest is payable. 

Section 5.07 Compliance Certificate and Opinions of Counsel. 

(a) Except as otherwise expressly provided in this Indenture, upon any application or request by the Company to the Trustee to
take any action under any provision of this Indenture, the Company shall furnish to the Trustee an Officer’s Certificate stating that all conditions precedent, if any, provided for in this Indenture relating to the proposed action have been
complied with and an Opinion of Counsel stating that in the opinion of such counsel all such conditions precedent, if any, have been complied with, except that in the case of any such application or request as to which the furnishing of such
documents is specifically required by any provision of this Indenture relating to such particular application or request, no additional certificate or opinion need be furnished. 

(b) Every certificate or opinion with respect to compliance with a condition or covenant provided for in this Indenture shall
include: 
 (i) a statement that each individual signing such certificate or opinion has read such covenant or condition and
the definitions herein relating thereto; 
 (ii) a brief statement as to the nature and scope of the examination or
investigation upon which the statements or opinions contained in such certificate or opinion are based; 
 (iii) a statement
that, in the opinion of each such individual, he has made such examination or investigation as is necessary to enable him to express an informed opinion as to whether or not such covenant or condition has been complied with; and 

(iv) a statement as to whether, in the opinion of each such individual, such condition or covenant has been complied with. 

(c) All applications, requests, certificates, statements or other instruments given under this Indenture shall be without
personal recourse to any individual giving the same and may include an express statement to such effect. 

  
 63 












 Section 5.08 Additional Interest. 

(a) If, at any time during the six-month period beginning on, and including, the date
which is six months after the Last Original Issuance Date of any Note, the Company fails to timely file any document or report that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, as
applicable (after giving effect to all applicable grace periods thereunder and other than current reports on Form 8-K), or such Note is not otherwise Freely Tradable, including pursuant to Rule 144 under the
Securities Act, by Holders other than “affiliates” (within the meaning of Rule 144) of the Company or Holders that were “affiliates” (within the meaning of Rule 144) of the Company during the three months immediately preceding
the date of the proposed transfer (as a result of restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes), then the Company shall pay Additional Interest that will accrue on such Note at the rate of 0.50% per annum
of the principal amount of such Note for each day during such period for which the Company’s failure to file has occurred and is continuing or such Note is not otherwise Freely Tradable; provided that such period shall end on the date
that is one year from the Last Original Issuance Date. 
 (b) If, and for so long as, the Restricted Notes Legend has not
been removed (or deemed removed) from the Notes, the Notes are not assigned (or deemed assigned) an unrestricted CUSIP number or the Notes are not otherwise Freely Tradable by Holders other than “affiliates” (within the meaning of Rule
144) of the Company or Holders that were “affiliates” (within the meaning of Rule 144) of the Company during the three months immediately preceding the date of the proposed transfer (without restrictions pursuant to U.S. securities laws or
the terms of this Indenture or the Notes) as of the De-Legending Deadline Date for such Notes, the Company will pay Additional Interest on such Notes. Additional Interest will accrue on such Notes at the rate
of 0.50% per annum of their principal amount outstanding until such Restricted Notes Legend is removed (or deemed removed), such Notes are assigned (or deemed assigned) an unrestricted CUSIP number and such Notes are Freely Tradable. 

(c) Such Additional Interest that is payable shall be payable in arrears on each Interest Payment Date following accrual in the
same manner as regular interest on the Notes and, subject to 5.08(d), will be in addition to any Additional Interest that may accrue as described under Section 6.03. 

(d) Notwithstanding anything to the contrary herein, in no event will any Additional Interest that may accrue as a result of
the Company’s failure to timely file any document or report that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace periods
thereunder and other than reports on Form 8-K), as described in this Section 5.08, together with any interest that may accrue as described in Section 6.03, accrue at a rate in excess of 0.50% per
annum, regardless of the number of events or circumstances giving rise to the requirement to pay such Additional Interest. 
 Section 5.09 Corporate
Existence. Subject to Article 9, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence. 

Section 5.10 Restriction on Resales. The Company shall not, and shall not permit any of its Subsidiaries to, and shall use its commercially
reasonable efforts to prohibit any other Affiliate of the Company from, reselling any of the Notes that have been reacquired by the Company or any of such Subsidiaries or Affiliates.

 REMEDIES 
 Section 6.01 Events of

time) in the aggregate of the Company and/or any of the Significant Subsidiaries of the Company, whether such indebtedness now exists or shall hereafter be created (i) resulting in such indebtedness becoming or being declared due and payable or
(ii) constituting a failure to pay the principal (or any unpaid interest that is due in connection with any failure to pay any such principal in excess of $50,000,000) of any such indebtedness when due and payable at its stated maturity, upon
required repurchase, upon declaration of acceleration or otherwise, and, in the case of clauses (i) and (ii) of this Section 6.01(g) such acceleration shall not, after the expiration of any applicable grace period, have been rescinded or

 Section 6.02 Acceleration; Waiver. 

(a) If an Event of Default (other than an Event of Default specified in Section 6.01(h) hereof or Section 6.01(i)
hereof with respect to the Company) occurs and is continuing, and is known to the Trustee, the Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the Notes then Outstanding by written notice to the Company and
the Trustee, may declare 100% of the principal of, and accrued and unpaid interest, if any, on all the Notes then Outstanding to be due and payable immediately. Upon such a declaration, such principal, and accrued and unpaid interest, if any, shall
be due and payable immediately. If an Event of Default specified in Section 6.01(h) or Section 6.01(i) 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 automatically become due and payable. 
 (b) The Holders of a majority in aggregate principal amount of Notes at the
time outstanding, by written notice to the Trustee and the Company, may waive any current Default or Event of Default (except with respect to (i) any failure by the Company to pay the principal of or accrued interest on the Notes (including the
Redemption Price and the Fundamental Change Repurchase Price, if applicable), (ii) any failure by the Company to comply with its obligations to repurchase Notes when required to do so under Article 3, (iii) any failure by the Company to pay or
deliver, as the case may be, the consideration due upon conversion of the Notes or (iv) any covenant or provision of this Indenture or the Notes that cannot be modified or amended without the consent of all Holders as provided for in
Section 8.02) and may rescind any acceleration of the Notes if (x) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (y) all existing Events of Default, other than the nonpayment of
the principal of and interest on the Notes have become due solely by such acceleration, have been cured or waived. 
 Section 6.03 Additional
Interest. 
 (a) Notwithstanding Section 6.02 hereof, to the extent the Company elects, the sole remedy for an Event
of Default under Section 6.01(f) relating to the Company’s failure to comply with Section 5.04(a) hereof (such Event of Default, a “Reporting Event of Default”), will (i) for the first 180 days after the
occurrence of such Reporting Event of Default (beginning on, and including, the date on which such Reporting Event of Default first occurs) consist exclusively of the right to receive Additional Interest on the Notes equal to 0.25% per annum of the
principal amount of such Notes then Outstanding for each day during such 180-day period on which such Event of Default is continuing and (ii) for the period from, and including, the 181st day after the
occurrence of such Reporting Event of Default to, and including the 360th day after the occurrence of such Reporting Event of Default, consist exclusively of the right to receive Additional Interest on the Notes 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 Reporting Event of Default is continuing (subject to Sections 6.03(d) and (f), in addition to any
Additional Interest that may accrue as described under Section 5.08). 

  
 67 












 (b) On the 361st day after the date on which the Reporting Event of Default
occurred (if such Reporting Event of Default has not been cured or waived prior to such 361st day), the Notes will be subject to acceleration as provided in Section 6.02 hereof. 

(c) In order to elect to pay the Additional Interest as the sole remedy during the first 360 days after the occurrence of a
Reporting Event of Default, the Company must notify in writing all Holders of Notes, the Trustee and the Paying Agent of such election prior to the beginning of such 360-day period. Upon the Company’s
failure to timely give such notice, the Notes shall be immediately subject to acceleration as provided in Section 6.02 hereof. In the event the Company does not elect to pay Additional Interest following a Reporting Event of Default or the
Company elects to pay Additional Interest but does not pay the Additional Interest when due, the Notes will be subject to acceleration as provided in Section 6.02 hereof. Except as provided in the Section 6.03(d) below, nothing in this
Section 6.03 shall affect the rights of Holders of Notes in the event of the occurrence of any other Event of Default. 

(d) Such Additional Interest will be payable in arrears on each Interest Payment Date following accrual in the same manner as
regular interest on the Notes and will be in addition to any Additional Interest that may accrue pursuant to Section 5.08. 

(e) With regard to any Reporting Event of Default, no Additional Interest shall accrue, and no right to declare the principal
or other amounts due and payable in respect of the Notes with respect to such Reporting Event of Default shall exist, after such Reporting Event of Default has been cured. 

(f) In no event shall Additional Interest payable at the Company’s election with regard to a Reporting Event of Default
(including any Additional Interest that may accrue as a result of the Company’s failure to comply with its obligations pursuant to Section 5.08) accrue at a rate in excess of 0.50% per annum, regardless of the number of events or
circumstances giving rise to the requirement to pay such Additional Interest. 
 Section 6.04 Control by Majority. At any time, the Holders of a
majority of the aggregate principal amount of the then Outstanding Notes may direct in writing the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the
Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or, subject to the Trustee’s duties under Article 10 hereof, that the Trustee determines to be unduly prejudicial to the rights of a
Holder or to the Trustee, or that would potentially involve the Trustee in personal liability unless the Trustee is offered (and if requested, provided) indemnity or security satisfactory to it against any loss, liability or expense to the Trustee
that may result from the Trustee’s instituting such proceeding as the Trustee. Prior to taking any action hereunder, the Trustee will be entitled to indemnification satisfactory to the Trustee against all losses, liabilities and expenses caused
or that may be caused by taking or not taking such action. 

  
 68 












 Section 6.05 Limitation on Suits. Subject to Section 6.06 hereof, no Holder may pursue a
remedy with respect to this Indenture or the Notes unless: 
 (a) such Holder has previously delivered to the Trustee written
notice that an Event of Default has occurred and is continuing; 
 (b) the Holders of at least 25% of the aggregate principal
amount of the then Outstanding Notes deliver to the Trustee a written request that the Trustee pursue a remedy with respect to such Event of Default; 

(c) such Holder or Holders have offered and, if requested, provided to the Trustee indemnity satisfactory to the Trustee
against any loss, liability or other expense of compliance with such written request; 
 (d) the Trustee has not complied
with such written request within 60 days after receipt of such written request and offer of indemnity or security; and 
 (e)
during such 60-day period, the Holders of a majority of the aggregate principal amount of the then Outstanding Notes did not deliver to the Trustee a direction inconsistent with such written request. 

Section 6.06 Rights of Holders to Bring Suit. Notwithstanding anything to the contrary elsewhere in this Indenture, the right of any Holder
to bring suit for the enforcement of any payment or delivery, as applicable, of the principal of, interest on, Fundamental Change Repurchase Price or Redemption Price, with respect to, on or after the respective due date, and to convert its Notes
and to bring suit for the enforcement of the payment or delivery of cash, shares of Common Stock or combination of cash and shares of Common Stock, if any, as the case may be, due with respect to such Notes in accordance with Article 4 hereof, will
not be impaired or affected without the consent of such Holder and will not be subject to the requirements of Section 6.05 hereof. 
 Section 6.07
Collection of Indebtedness; Suit for Enforcement by Trustee. If an Event of Default specified in Section 6.01(a), 6.01(b) or 6.01(c) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as
trustee of an express trust against the Company for the whole amount of principal of, interest on, Fundamental Change Repurchase Price or Redemption Price for, and the amount of cash, the number of shares of Common Stock or the combination of cash
and shares of Common Stock, if any, as the case may be, due upon the conversion of, the Notes, as the case may be, and such further amount as is sufficient to cover the costs and expenses of collection, including the compensation and reasonable
expenses, disbursements and advances of the Trustee, its agents and counsel, as well as any other amounts that may be due under Section 10.07 hereof. 

Section 6.08 Trustee May Enforce Claims Without Possession of Notes. All rights of action and claims under this Indenture or the Notes may
be prosecuted and enforced by the Trustee without the possession of any of the Notes or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an
express trust, and any recovery of judgment shall, after provision for the payment of the compensation, and reasonable expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders in respect
of which such judgment has been recovered. 

  
 69 












 Section 6.09 Trustee May File Proofs of Claim. The Trustee is authorized to file such proofs of
claim and other papers or documents as may be necessary or advisable to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Company, its creditors or its property and, unless prohibited by law or
applicable regulations, will be entitled to collect, receive and distribute any money or other property payable or deliverable on any such claims, and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such
payments to the Trustee, and, in the event that the Trustee consents to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the compensation and reasonable expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under Section 10.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any
other amounts due the Trustee under Section 10.07 hereof out of the estate in any such proceeding, will be denied for any reason, payment of the same will be secured by a lien on, and is paid out of, any and all distributions, dividends, money,
securities and other properties that the Holders may be entitled to receive in such proceeding, whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained will be deemed to authorize the Trustee
to authorize or consent to, or to accept or to adopt on behalf of any Holder, any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the
claim of any Holder in any such proceeding. 
 Section 6.10 Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any
proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as
though no such proceeding had been instituted. 
 Section 6.11 Rights and Remedies Cumulative. Except as otherwise provided with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Notes in Section 2.09 hereof, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and
every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or
remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 
 Section 6.12
Delay or Omission Not a Waiver. No delay or omission of the Trustee or of any Holder to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default
or an acquiescence therein. Every right and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time and as often as may be deemed expedient by the Trustee (subject to the limitations contained in
this Indenture) or by the Holders, as the case may be.

 Section 6.13 Priorities. If the Trustee collects any money or property pursuant to this Article
6, it will pay out the money or property in the following order: 
 FIRST: to the Trustee, its agents and attorneys for amounts due under
Section 10.07 hereof, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 

SECOND: to the Holders, for any amounts due and unpaid on the principal of, accrued and unpaid interest on, Fundamental Change Repurchase
Price or Redemption Price for, and any cash due upon conversion of, any Note, without preference or priority of any kind, according to such amounts due and payable on all of the Notes; and 

THIRD: the balance, if any, to the Company or to such other party as a court of competent jurisdiction directs. 

The Trustee may fix a record date and payment date for any payment to the Holders pursuant to this Section 6.13. If the Trustee so fixes
a record date and a payment date, at least 15 calendar days prior to such record date, the Trustee will deliver to each Holder a written notice, which notice will state such record date, such payment date and the amount of such payment. 

Section 6.14 Undertaking for Costs. All parties to this Indenture agree, and each Holder, by such Holder’s acceptance of a Note, shall be
deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken 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, however, that the provisions of this Section 6.14 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 aggregate principal amount of the Notes then Outstanding, or to any suit instituted by any Holder for the enforcement of the payment of the principal of,
accrued and unpaid interest, if any, on, Fundamental Change Repurchase Price or Redemption Price for, any Note on or after the due date expressed or provided for in this Indenture or to any suit for the enforcement of the right to convert any Note
in accordance with the provisions of Article 4 hereof. 
 Section 6.15 Waiver of Stay, Extension and Usury Laws. The Company covenants that, to
the extent that it may lawfully do so, it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that
may affect the covenants or the performance of this Indenture; and the Company, to the extent that 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 instead suffer and permit the execution of every such power as though no such law has been enacted.

Date, any Fundamental Change Repurchase Date, any Redemption Date, upon conversion or otherwise) and the Company shall deposit with the Trustee, in trust, or deliver to the Holders, as applicable, an amount of cash, a number of shares of Common
Stock, or a combination of cash and shares of Common Stock, if any, as the case may be (solely to settle amounts due with respect to outstanding conversions), sufficient to pay all amounts due on all of such Notes (other than any Notes that shall
have been mutilated, destroyed, lost or stolen and in lieu of or in substitution for which other Notes shall have been authenticated and delivered) not theretofore canceled or delivered to the Trustee for cancellation, including principal and
interest due, accompanied, except in the event the Notes are due and payable solely in cash at the Maturity Date or upon an earlier Fundamental Change Repurchase Date or Redemption Date, by a verification report as to the sufficiency of the
deposited amount from an independent certified accountant or other financial professional, and if the Company shall also pay or cause to be paid all other sums payable hereunder by the Company, then this Indenture shall cease to be of further effect
(except as to (i) rights hereunder of Holders to receive from such trust all amounts owing upon the Notes and the other rights, duties and obligations of Holders, as beneficiaries hereof with respect to the amounts, if any, so deposited with
the Trustee and (ii) the rights, obligations and immunities of the Trustee hereunder), and the Trustee, on written demand of the Company accompanied by an Officer’s Certificate and an Opinion of Counsel and at the cost and expense of the
Company, shall execute such instruments reasonably requested by the Company acknowledging satisfaction and discharge of this Indenture and the Notes; the Company, however, hereby agrees to reimburse the Trustee for any costs or expenses thereafter
reasonably and properly incurred by the Trustee, including the fees and expenses of its counsel, and to compensate the Trustee its services thereafter in accordance with Section 10.07. 

Section 7.02 Deposited Monies to Be Held in Trust by Trustee. Subject to Section 7.04 hereof, all monies and shares of Common Stock, as the
case may be, deposited with the Trustee pursuant to Section 7.01 hereof shall be held in trust for the sole benefit of the Holders of the Notes, and such monies and shares of Common Stock shall be applied by the Trustee to the payment, either
directly or through any Paying Agent (including the Company if acting as its own Paying Agent), to the Holders of the particular Notes for the payment or settlement of which such monies or shares of Common Stock, or both, as the case may be, have
been deposited with the Trustee, of all sums or amounts due and to become due thereon for principal and interest, if any. 
 Section 7.03 Paying
Agent to Repay Monies Held. Upon the satisfaction and discharge of this Indenture, all monies and shares of Common Stock, as the case may be, then held by any Paying Agent (if other than the Trustee) shall, upon written request of the Company,

 72 












 Section 7.04 Return of Unclaimed Monies. Subject to the requirements of applicable law, any
monies and shares of Common Stock deposited with or paid to the Trustee for payment of the principal of or interest, if any, on the Notes and not applied but remaining unclaimed by the Holders of the Notes for two (2) years after the date upon
which the principal of or interest, if any, on such Notes, as the case may be, shall have become due and payable, shall be repaid to the Company by the Trustee on demand, and all liability of the Trustee shall thereupon cease with respect to such
monies and shares of Common Stock; and the Holder shall thereafter look only to the Company for any payment or delivery that such Holder may be entitled to collect unless an applicable abandoned property law designates another Person. 

Section 7.05 Reinstatement. If the Trustee or the Paying Agent is unable to apply any money or shares of Common Stock, or both, as the case may
be, in accordance with Section 7.02 hereof by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under the Indenture and the
Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 7.01 hereof until such time as the Trustee or the Paying Agent is permitted to apply all such money and shares of Common Stock in accordance with
Section 7.02 hereof; provided, however, that if the Company makes any payment of interest on, principal of or payment or delivery in respect of any Note following the reinstatement of its obligations, the Company shall be
subrogated to the rights of the Holders of such Notes to receive such payment from the money or shares of Common Stock, if any, held by the Trustee or Paying Agent.

if the Company is not the Successor Company, all the conditions specified in Section 9.03 are met. 
 Upon any such amalgamation,
consolidation, merger, conveyance, transfer or lease, the Successor Company (if not the Company) shall succeed to, and may exercise every right and power of the Company under this Indenture, and the Company shall be discharged from its obligations
under the Notes and the Indenture except in the case of any such lease. 
 Notwithstanding the foregoing, this Section 9.01 will not
apply to any conveyance, transfer or lease of properties or assets to the Company or to one or more of the Company’s direct or indirect Subsidiaries that are wholly-owned or that would be wholly-owned but for any directors’ qualifying
shares as required by law or shares held by nominees on behalf of such Subsidiaries as required by law. 
 Section 9.02 Successor
Corporation to Be Substituted. In case of any such amalgamation, consolidation, merger, conveyance, transfer or lease and upon the assumption by the Successor Company (if other than the Company), by supplemental indenture, executed and delivered
to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of (including any Fundamental Change Repurchase Price and any Redemption Price), if any, accrued and unpaid interest, if any, on all of the
Notes, the due and punctual delivery or payment, as the case may be, of any Settlement Amount due upon conversion of the Notes and the due and punctual performance of all of the covenants and conditions of this


  
 76 












 
Indenture to be performed by the Company under this Indenture, such Successor Company shall succeed to and be substituted for, and may exercise every right and power of, the Company under this
Indenture, with the same effect as if it had been named herein as the party of the first part; provided, however, that in the case of a conveyance, transfer or lease to one or more of its Subsidiaries of all or substantially all of the
properties and assets of the Company, the Notes will remain convertible based on the Common Stock and into cash, shares of Common Stock, or a combination of cash and shares of Common Stock, if any, as the case may be, in accordance with
Section 4.03 hereof, but subject to adjustment (if any) in accordance with Section 4.07 hereof. Such Successor Company thereupon may cause to be signed, and may issue either in its own name or in the name of the Company any or all of the
Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such Successor Company instead of the Company and subject to all the terms, conditions and limitations in this
Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that previously shall have been signed and delivered by the Officers of the Company to the Trustee for authentication, and
any Notes that such Successor Company thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under this Indenture as the Notes theretofore
or thereafter issued in accordance with the terms of this Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such amalgamation, consolidation, merger, conveyance or transfer (but not in the
case of a lease), the Person named as the “Company” in the first paragraph of this Indenture or any successor that shall thereafter have become such in the manner prescribed in this Article 9 may be dissolved, wound up and liquidated
at any time thereafter and, except in the case of a lease, such Person shall be released from its liabilities as obligor and maker of the Notes and from its obligations under this Indenture. 

In case of any such amalgamation, consolidation, merger, 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 9.03 Opinion of Counsel to Be Given to Trustee. In
the case of any amalgamation, merger, consolidation, conveyance, transfer or lease under this Article 9, the Trustee shall receive an Officer’s Certificate and an Opinion of Counsel stating that any such amalgamation, consolidation, merger,
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 Indenture. 

ARTICLE 10. 
 THE TRUSTEE 

Section 10.01 Duties and Responsibilities of Trustee. 

(a) The Trustee, prior to the occurrence of an Event of Default and after the curing of all Events of Default which may have
occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee. In case an Event of Default has occurred
(which has not been cured or waived) and the Trustee has notice of such fact, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care in their exercise, as a prudent person would use
in the conduct of his or her own affairs. 

  
 77 












 (b) No provision of this Indenture shall be construed to relieve the Trustee
from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that: 

(i) prior to the occurrence of an Event of Default and after the curing or waiving of all Events of Default which may have
occurred: 
 (A) the duties and obligations of the Trustee shall be determined solely by the express provisions of this
Indenture and applicable law, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture
against the Trustee; and 
 (B) in the absence of bad faith on the part of the Trustee, the Trustee may conclusively rely as
to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but, in the case of any such certificates or
opinions which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture (but need not
confirm or investigate the accuracy of any mathematical calculations or other facts stated therein); 
 (ii) the Trustee
shall not be liable for any error of judgment made in good faith by a Responsible Officer or Officers of the Trustee, unless the Trustee was negligent in ascertaining the pertinent facts;

with the written direction of the Holders of not less than a majority in principal amount of the Notes at the time Outstanding determined as provided in Section 1.03 relating to the time, method and place of conducting any proceeding for any
remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture; 
 (iv)
whether or not therein provided, every provision of this Indenture relating to the conduct or affecting the liability of, or affording protection to, the Trustee shall be subject to the provisions of this Section 10.01; 

  
 78 












 (v) the Trustee shall not be liable in respect of any payment (as to the
correctness of amount, entitlement to receive or any other matters relating to payment) or notice effected by the Company or any Paying Agent or any records maintained by any co-Registrar with respect to the
Notes; and 
 (vi) if any party fails to deliver a notice relating to an event the fact of which, pursuant to this Indenture,
requires notice to be sent to the Trustee, the Trustee may conclusively rely on its failure to receive such notice as reason to act as if no such event occurred. 

None of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial
liability in the performance of any of its duties or in the exercise of any of its rights or powers, if there is reasonable ground for believing that the repayment of such funds or indemnity or security satisfactory to the Trustee against such risk
or liability is not reasonably assured to it. 
 Section 10.02 Notice of Defaults. The Trustee shall give the Holders notice of any Default of
which the Trustee has knowledge or is deemed to have notice under Section 10.01(a) within 90 days after the occurrence thereof so long as such Default is continuing; provided, that (except in the case of any Default in the payment of
principal amount of, or interest on, any of the Notes or Fundamental Change Repurchase Price or Redemption Price or a Default in the delivery of the consideration due upon conversion), the Trustee shall be protected in withholding such notice if and
so long as it in good faith determines that the withholding of such notice is in the interest of the Holders of Notes. 
 Section 10.03 Reliance on
Documents, Opinions, Etc. Except as otherwise provided in Section 10.01: 
 (a) the Trustee may conclusively rely
and shall be protected in acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, debenture, note, coupon or other paper or document (whether in its original or facsimile form) believed
by it in good faith to be genuine and to have been signed or presented by the proper party or parties;

request, order or direction of any of the Holders pursuant to the provisions of this Indenture (including upon the occurrence and during the continuance of an Event of Default), unless such Holders shall have offered (and if requested, provided) to
the Trustee security or indemnity satisfactory to it against any loss, expenses and liabilities which may be incurred therein or thereby; 

  
 79 












 (e) the Trustee shall not be bound to make any investigation into the facts
or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may make such further inquiry or
investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or
attorney (at the reasonable expense of the Company and shall incur no liability of any kind by reason of such inquiry or investigation); 

(f) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or
through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed by it with due care hereunder;

no event shall the Trustee be responsible or liable for special, indirect, consequential or punitive loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the
likelihood of such loss or damage and regardless of the form of action; 
 (i) the Trustee shall not be deemed to have notice
of any Default or Event of Default unless written notice of any event which is in fact such a Default is received by a Responsible Officer of the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes and the
Indenture; 
 (j) the rights, privileges, protections, immunities and benefits given to the Trustee, including, without
limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, Custodian and other Person employed to act hereunder; 

(k) the Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties
hereunder; 
 (l) the Trustee may request that the Company deliver a certificate setting forth the names of individuals

 (m) any
discretion, permissive right or privilege in favor of the Trustee, if any, shall not be construed as a duty or obligation. 
 Section 10.04 No
Responsibility for Recitals, Etc. The recitals contained herein and in the Notes (except in the Trustee’s certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the
correctness of the same. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Notes. The Trustee shall not be accountable for the use or application by the Company of any Notes or the proceeds of any
Notes authenticated and delivered by the Trustee in conformity with the provisions of this Indenture. 

  
 80 












 Section 10.05 Trustee, Paying Agents, Exchange Agents or Registrar May Own Notes. The Trustee,
any Paying Agent, any Conversion Agent or Registrar, in its individual or any other capacity, may become the owner or pledgee of Notes with the same rights it would have if it were not Trustee, Paying Agent, Conversion Agent or Registrar. 

Section 10.06 Monies to be Held in Trust. Subject to the provisions of Section 10.07, all monies and properties received by the Trustee
shall, until used or applied as herein provided, be held in trust for the purposes for which they were received. Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee
shall be under no liability for interest on any money received by it hereunder except as may be agreed in writing from time to time by the Company and the Trustee. 

Section 10.07 Compensation and Expenses of Trustee. The Company covenants and agrees to pay to the Trustee from time to time, and the
Trustee shall be entitled to, such compensation for all services rendered by it hereunder in any capacity (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) as mutually agreed to from
time to time in writing between the Company and the Trustee, and the Company will pay or reimburse the Trustee upon its request for all reasonable, out-of-pocket
expenses, disbursements and advances reasonably incurred or made by the Trustee in accordance with any of the provisions of this Indenture (including the reasonable compensation and the expenses and disbursements of its counsel and of all Persons
not regularly in its employ) except any such expense, disbursement or advance as may arise from its gross negligence or willful misconduct. 

The Company also covenants to indemnify the Trustee (or any officer, director or employee of the Trustee), in any capacity under this
Indenture and its agents and any Authenticating Agent for, and to hold them harmless against, any and all loss, liability, claim or expense incurred without gross negligence or willful misconduct on the part of the Trustee or such officers,
directors, employees and agent or Authenticating Agent, as the case may be, and arising out of or in connection with the acceptance or administration of this trust or in any other capacity hereunder, including the costs and expenses of defending
themselves against any claim (whether asserted by the Company, a Holder or any other Person) of liability in the premises. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so
notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have one firm of separate counsel except in the event local counsel
shall be required and the Company shall pay the reasonable fees and expenses of such counsel and local counsel, as applicable. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld.

 The obligations of the Company under this Section 10.07 to compensate or indemnify the Trustee and to pay or reimburse the Trustee
for expenses, disbursements and advances shall be secured by a lien prior to that of the Notes upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the Holders of particular Notes. The
obligation of the Company under this Section shall survive the satisfaction and discharge of this Indenture or the resignation or removal of the Trustee. “Trustee” for purposes of this Section 10.07 shall include any predecessor
Trustee; provided, however, the gross negligence or willful misconduct of any Trustee hereunder shall not affect the rights of any other Trustee hereunder. 

  
 81 












 When the Trustee and its agents and any Authenticating Agent incur expenses or render
services after an Event of Default specified in Section 6.01(h) and 6.01(i) with respect to the Company occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any bankruptcy,
insolvency or similar laws. 
 Section 10.08 Officer’s Certificate as Evidence. Except as otherwise provided in
Section 10.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or omitting any action hereunder, such matter (unless
other evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence or willful misconduct on the part of the Trustee, be deemed to be conclusively proved and established by an Officer’s Certificate delivered
to the Trustee. 
 Section 10.09 Eligibility of Trustee. There shall at all times be a Trustee hereunder which shall be a Person that has
a combined capital and surplus of at least $50,000,000 (or if such Person is a member of a bank holding company system, its bank holding company shall have a combined capital and surplus of at least $50,000,000). If such Person publishes reports of
condition at least annually, pursuant to law or to the requirements of any supervising or examining authority, then for the purposes of this Section the combined capital and surplus of such Person shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 10.09, it shall resign immediately in the manner and with the
effect hereinafter specified in this Article. 
 Section 10.10 Resignation or Removal of Trustee. 

(a) The Trustee may at any time resign by giving written notice of such resignation to the Company and to the Holders of Notes.
Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning
Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment thirty (30) days after the mailing of such notice of resignation to the Holders, the resigning Trustee may, upon
ten (10) Business Days’ notice to the Company and the Holders, petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor trustee, or, if any Holder who has been a bona fide Holder of a
Note or Notes for at least six (6) months may, subject to the provisions of Section 6.14, on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon,
after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee. 
 (b) In case at any time any
of the following shall occur: 

  
 82 












 (i) the Trustee shall cease to be eligible in accordance with the provisions
of Section 10.09 and shall fail to resign after written request therefor by the Company or by any such Holder; or 

(ii) the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee
or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation; 

then, in any such case, the Company may remove the Trustee and appoint a successor trustee by written instrument, in duplicate, executed by
order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of Section 6.14, any Holder who has been a bona fide Holder of a
Note or Notes for at least six (6) months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee; provided,
however, that if no successor Trustee shall have been appointed and have accepted appointment thirty (30) days after either the Company or the Holders has removed the Trustee, the Trustee so removed may petition at the Company’s
expense any court of competent jurisdiction for an appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. 

(c) The Holders of a majority in aggregate principal amount of the Notes at the time Outstanding may at any time remove the
Trustee and nominate a successor trustee which shall be deemed appointed as successor trustee unless, within ten (10) days after notice to the Company of such nomination, the Company objects thereto, in which case the Trustee so removed or any
Holder, or if such Trustee so removed or any Holder fails to act, the Company, upon the terms and conditions and otherwise as provided in Section 10.10(a), may petition, at the expense of the Company, any court of competent jurisdiction for an
appointment of a successor trustee. 
 (d) Any resignation or removal of the Trustee and appointment of a successor trustee
pursuant to any of the provisions of this Section 10.10 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 10.11. 

Section 10.11 Acceptance by Successor Trustee. Any successor trustee appointed as provided in Section 10.10 shall execute, acknowledge
and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee herein; but, nevertheless, on the written request of the Company or of
the successor trustee, the trustee ceasing to act shall, upon payment of any amount then due it pursuant to the provisions of Section 10.07, execute and deliver an instrument transferring to such successor trustee all the rights and powers of
the trustee so ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting 

  
 83 












 
in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a lien upon all property and funds held or collected by such trustee
as such, except for funds held in trust for the benefit of Holders of particular Notes, to secure any amounts then due it pursuant to the provisions of Section 10.07. 

No successor trustee shall accept appointment as provided in this Section 10.11 unless, at the time of such acceptance, such successor
trustee shall be eligible under the provisions of Section 10.09. 
 Upon acceptance of appointment by a successor trustee as provided
in this Section 10.11, the Company (or the former trustee, at the written direction of the Company) shall mail or cause to be mailed notice of the succession of such trustee hereunder to the Holders of Notes at their addresses as they shall
appear on the Register. If the Company fails to mail such notice within ten (10) days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Company. 

Section 10.12 Succession by Merger, Etc. Any corporation into which the Trustee may be merged or exchanged or with which it may be consolidated,
or any corporation resulting from any merger, exchange or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee (including any trust created by
this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that in the case of any corporation succeeding to all or
substantially all of the corporate trust business of the Trustee, such corporation shall be eligible under the provisions of Section 10.09. 

In case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture, any of the Notes shall have been
authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or Authenticating Agent appointed by such predecessor trustee, and deliver such Notes so authenticated; and in
case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or any Authenticating Agent appointed by such successor trustee may authenticate such Notes in the name of the successor trustee; and in all such
cases such certificates shall have the full force that is provided in the Notes or in this Indenture; provided, however, that the right to adopt the certificate of authentication of any predecessor trustee or authenticate Notes in the
name of any predecessor trustee shall apply only to its successor or successors by merger, exchange or consolidation. 
 Section 10.13
Trustee’s Application for Instructions from the Company. Any application by the Trustee for written instructions from the Company (other than with regard to any action proposed to be taken or omitted to be taken by
the Trustee that affects the rights of the Holders of the Notes under this Indenture) may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after
which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in
such application (which date shall not be less than three (3) Business Days after the date any officer of the Company actually receives such application, unless any such officer shall have consented in writing to any earlier date) unless prior
to taking any such action (or the effective date in the case of an omission), the Trustee shall have received written instructions in response to such application specifying the action to be taken or omitted.

 85 












 Section 11.03 Redemption Notice. The Redemption Notice, if delivered in the
manner herein provided, shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such Redemption Notice by mail or any defect in the Redemption Notice to the Holder of any

(ii) the Redemption Price; 

(iii) in the case of a partial redemption, which Notes have been called for redemption;

(c) A Redemption Notice shall be irrevocable. 

  
 86 












 Section 11.04 Payment of Notes Called for Redemption. 

(a) If any Redemption Notice has been given in respect of the Notes in accordance with Section 11.01(b) and
Section 11.03, the Notes shall become due and payable on the Redemption Date at the place or places stated in the Redemption Notice and at the applicable Redemption Price. On presentation and surrender of the Notes at the place or places stated
in the Redemption Notice, the Notes shall be paid and redeemed by the Company at the applicable Redemption Price. Any Notes redeemed by the Company shall be paid in cash. 

(b) Prior to the Open of business on the Redemption Date, the Company shall deposit with the Paying Agent or, if the Company is
acting as the Paying Agent, shall segregate and hold in trust as provided in Section 10.06, an amount of cash (in immediately available funds if deposited on the Redemption Date) sufficient to pay the Redemption Price for all of the Notes to be
redeemed on such Redemption Date. Subject to the Paying Agent holding money sufficient to pay the Redemption Price for all of the Notes to be redeemed on such Redemption Date, upon surrender of any Note for redemption in accordance with the
Redemption Notice, payment for the Notes to be redeemed shall be made on the Redemption Date for such Notes.

amounts due upon redemption in respect of the Notes presented for redemption shall be paid by the Company to such Holder, or such Holder’s nominee or nominees. The Paying Agent shall, promptly after such payment and upon written demand by the
Company, return to the Company any funds in excess of the Redemption Price. 
 Section 11.05 Redemption in Part. 

(a) If fewer than all of the outstanding Notes are to be redeemed and the Notes to be redeemed are Global Notes, the Depositary
shall select the Notes to be redeemed in accordance with the Applicable Procedures. If fewer than all of the outstanding Notes are to be redeemed and the Notes to be redeemed are Physical Notes in certificated form, the Trustee shall select the
Notes or portions thereof to be redeemed (in principal amounts of $1,000 or multiples thereof) by lot, on a pro rata basis, or by another method the Trustee considers to be fair and appropriate. If any Note selected for partial redemption by
the Trustee is submitted for conversion in part after such selection, the portion of the Note submitted for conversion shall be deemed (so far as may be possible) to be the portion selected for redemption. 

(b) In the event of any redemption in part, the Company, the Trustee and the Registrar shall not be required to register the
transfer of or exchange any Notes so selected for redemption, in whole or in part, except the unredeemed portion of any Notes being redeemed in part.

 Section 11.06 Restrictions on Redemption. The Company may not redeem any Notes
on any date if the principal amount of the Notes has been accelerated in accordance with the terms of this Indenture, and such acceleration has not been rescinded, on or prior to the Redemption Date (including as a result of the payment of the
Redemption Price and any related interest on the Redemption Date). 
 Section 11.07 Special Provisions for Partial Calls. If the
Company elects to redeem less than all of the outstanding Notes pursuant to this Article 11, and the Holder of any Note, or any owner of a beneficial interest in any Global Note, is reasonably not able to determine, before the Close of Business on
the 42nd Scheduled Trading Day immediately before the Redemption Date for such Optional Redemption, whether such Note or beneficial interest, as applicable, is to be redeemed pursuant to such Optional Redemption, then if such Holder or owner, as
applicable, elects to convert such Note or beneficial interest, as applicable, at any time before the Close of Business on the second Business Day immediately before such Redemption Date, each such conversion will be deemed to be of a Note called
for Redemption for purposes of this Article 11 and Section 4.06. 
 The Trustee shall have no obligation to determine whether a Holder
or beneficial owner of any Note is to be redeemed in the event of a partial redemption, and shall have no obligation to calculate the Conversion Rate or any increase thereof as a result of an Optional Redemption. In the case of Global Notes, any
redemption and conversion of Notes in connection with a redemption shall be subject to the Applicable Procedures. 
 ARTICLE 12. 

MISCELLANEOUS

Section 12.02 Governing Law. This Indenture and the Notes, and any claim, controversy or dispute arising under or related to the Indenture or the
Notes, will be governed by, and construed in accordance with, the laws of the State of New York. To the fullest extent permitted by applicable law, the Company hereby irrevocably submits to the jurisdiction of any Federal or State court located in
the Borough of Manhattan in The City of New York, New York in any suit, action or proceeding based on or arising out of or relating to this Indenture or any Notes and irrevocably agrees that all claims in respect of such suit or proceeding may be
determined in any such court. The Company irrevocably waives, to the fullest extent permitted by law, any objection which it may have to the laying of the venue of any such suit, action or proceeding brought in an inconvenient forum. The Company
agrees that final judgment in any such suit, action or proceeding brought in such a court shall be conclusive and binding upon the Company, and may be enforced in any courts to the jurisdiction of which the Company is subject by a suit upon such

 Section 12.04 Voting. In determining whether the Holders of the requisite aggregate principal
amount of Notes have concurred in any direction, consent, waiver or other action under this Indenture, Notes that are owned by the Company, by any of its Subsidiaries or by any Person directly or indirectly controlling or controlled by or under
direct or indirect common control with the Company or any of its Subsidiaries shall be disregarded and deemed not to be Outstanding for the purpose of any such determination, except that for the purposes of determining whether the Trustee shall be
protected in relying upon any request, demand, authorization, direction, notice, consent or waiver or other action that is to be made by a requisite principal amount of Outstanding Notes, only such Notes which a Responsible Officer of the Trustee
actually knows to be so owned shall be disregarded. Notes so owned that have been pledged in good faith may be regarded as Outstanding for such purposes if the pledgee shall establish its right to so act with respect to such Notes and that the
pledgee is not the Company, one of its Subsidiaries or a Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or one of its Subsidiaries. 

Section 12.05 Benefits of Indenture. Nothing in this Indenture or in the Notes, expressed or implied, will give to any

the Notes, the Daily Conversion Values, the Daily Settlement Amounts, accrued interest payable on the Notes, Additional Interest, if any, any Redemption Price and the Conversion Rate, including adjustments to the Conversion Price and the Conversion

Holders, the Trustee and the Conversion Agent. The Company shall provide a schedule of its calculations to each of the Trustee, the Bid Solicitation Agent and the Conversion Agent, and each of the Trustee, the Bid Solicitation Agent and the
Conversion Agent is entitled to rely conclusively upon the accuracy of the Company’s calculations without independent verification. The Trustee shall forward the Company’s calculations to any Holders upon the written request of that
Holder.

 Section 12.08 Notices, Etc. to Trustee and Company. 

(a) Except as otherwise provided herein, any request, demand, authorization, direction, notice, consent, election, waiver or
Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with, 

(i) the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or
filed in writing (including facsimile or electronically in PDF format) to or with the Trustee at its Corporate Trust Office; or 

(ii) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein
expressly provided) if in writing and mailed, first-class postage prepaid (and, in the case of securities held in book-entry form, by electronic transmission), to the Company addressed to it at the address of its principal office at 1001 Ridder Park
Drive, San Jose, CA 95131, Attn: Secretary and General Counsel or at any other address furnished in writing to the Trustee by the Company prior to such mailing or electronically in PDF format. 

(b) The Company or the Trustee, by notice given to the other in the manner provided in this Section 12.08, may designate
additional or different addresses for subsequent notices or communications. 
 (c) Whenever the Company is required to
deliver notice to the Holders, the Company will, by the date it is required to deliver such notice to the Holders, deliver a copy of such notice to the Trustee, the Paying Agent, the Registrar and the Conversion Agent. Each notice to the Trustee,
the Paying Agent, the Registrar and the Conversion Agent shall be sufficiently given upon actual receipt by the Trustee, Paying Agent, Registrar or Conversion Agent (as the case may be). 

(d) Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to
receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by the Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such waiver. 
 (e) Where this Indenture provides for notice of any event to a Holder of a
Global Note, such notice shall be sufficiently given if given to the Depositary for such Note (or its designee), pursuant to its Applicable Procedures, not later than the latest date (if any), and not earlier than the earliest date (if any),
prescribed for the giving of such notice. 
 Section 12.09 No Recourse Against Others. No director, officer, employee, incorporator or
stockholder of the Company shall have any liability for any obligations of the Company under the Notes, the Indenture or any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder, by accepting a Note, waives
and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

 Section 12.10 Tax Withholding. Notwithstanding anything herein to the contrary, the Company or
any other withholding agent is permitted to withhold, or backup withhold, from interest payments and payments upon conversion, redemption, repurchase, or maturity of the Notes, any amounts the Company or other withholding agent is required to
withhold or backup withhold by law. If the Company or other withholding agent pays withholding taxes or backup withholding on behalf of a Holder or beneficial owner, the Company or other withholding agent may, at its option, set off any such payment
against payments of cash and Common Stock payable on the Notes (or, in some circumstances, any payments on Common Stock), or sales proceeds received by or other funds or assets of such Holder or beneficial owner held with a withholding agent. 

Section 12.11 Waiver of Jury Trial. EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE
LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTION CONTEMPLATED HEREBY. 

Section 12.12 U.S.A. Patriot Act. The parties hereto acknowledge that in accordance with Section 326 of the U.S.A. Patriot Act, the Trustee,
like all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify, and record information that identifies each Person or legal entity that establishes a relationship or opens an
account with the Trustee. The parties to this Indenture agree that they will provide the Trustee with such information as it may request in order for the Trustee to satisfy the requirements of the U.S.A. Patriot Act. 

Section 12.13 Force Majeure. In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations
hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or
acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the
banking industry to resume performance as soon as practicable under the circumstances. 
 Section 12.14 Legal Holidays. In any case where any
Interest Payment Date, Fundamental Change Repurchase Date, Redemption Date, Conversion Date or Maturity Date is not a Business Day (which, solely for the purposes of any payment required to be made on any such Interest Payment Date, Fundamental
Change Repurchase Date, Redemption Date, Conversion Date or Maturity Date and solely for purposes of this Section, shall also not include days in which the office where the place of payment in the continental United States is authorized or required
by law to close), then such Interest Payment Date, Fundamental Change Repurchase Date, Redemption Date, Conversion Date or Maturity Date, as applicable, will not be postponed but any action (which shall be limited to solely any payment action in the
case the immediately preceding parenthetical applies) to be taken on such date need not be taken on such date, but may be taken on the next succeeding Business Day with the same force and effect as if taken on such date, and no interest shall accrue
or be paid in respect of the delay.

 [FORM OF REVERSE OF NOTE] 

Lumentum Holdings Inc. 
 0.50%
Convertible Senior Notes due 2026 
 This Note is one of a duly authorized issue of securities of the Company (herein called the “Notes”),
issued under the Indenture, dated as of December 12, 2019, by and between the Company and U.S. Bank National Association, as trustee herein called the “Trustee,” and reference is hereby made to the Indenture for a statement of
the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. In the event of a conflict
between the terms of the Indenture and this Note, the terms of the Indenture shall govern. 
 The Company will pay cash interest on the
unpaid principal amount of this Note at a rate of 0.50% per year. Interest will accrue from the most recent date on which interest has been paid or duly provided for or, if no interest has been paid, from
[                ][insert December 12, 2019 for Initial Notes]. Except as provided in the Indenture, interest will be paid to the Person in whose name
this Note is registered at the Close of Business on the Regular Record Date immediately preceding the relevant Interest Payment Date semiannually in arrears on each Interest Payment Date; provided that, if any Interest Payment Date, Maturity
Date, Redemption Date, or Fundamental Change Repurchase Date with respect to this Note falls on a day that is not a Business Day, the required payment will be made on the next succeeding Business Day and no interest on such payment will accrue in
respect of the delay. Interest on the Notes shall be computed on the basis of a 360-day year consisting of twelve 30-day months and, for partial months, on the basis of
the number of days actually elapsed in a 30-day month. Except as provided in the Indenture, no interest shall be paid with respect to Notes surrendered for conversion. 

As provided in and subject to the provisions of the Indenture, the Company may redeem this Note on or after December 20, 2023 under
certain conditions specified in Article 11 of the Indenture. This Note does not benefit from a sinking fund. 
 As provided in and subject
to the provisions of the Indenture, upon the occurrence of a Fundamental Change the Holder of this Note will have the right, at such Holder’s option, to require the Company to repurchase this Note, or any portion of this Note such that the
principal amount of this Note that is not repurchased equals $1,000 or an integral multiple of $1,000 in excess thereof, on the Fundamental Change Repurchase Date at a price equal to the Fundamental Change Repurchase Price for such Fundamental
Change Repurchase Date. 
 As provided in and subject to the provisions of the Indenture, the Holder hereof has the right, at its option
(i) 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 September 15, 2026, and (ii) on or after September 15,
2026, at any time prior to the Close of Business on the second Scheduled Trading Day immediately preceding the Maturity Date, to convert this Note or a portion of this Note such that the principal amount of this Note that is not converted equals
$1,000 or an integral multiple of $1,000 in excess thereof, into an amount of cash, a number of shares of Common Stock, or a combination of cash and shares of Common Stock, if any, as the case may be, determined in accordance with Article 4 of the
Indenture. 

  
 A-5 












 As provided in and subject to the provisions of the Indenture, the Company will make all
payments in respect of the Fundamental Change Repurchase Price or Redemption Price for, and the principal amount of, this Note to the Holder that surrenders this Note to the Paying Agent to collect such payments in respect of this Note. The Company
will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. 

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations
of the Company and the rights of the Holders of the Notes to be effected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Notes at the time Outstanding. The
Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Notes at the time Outstanding, on behalf of the Holders of all Notes, to waive compliance by the Company with certain provisions of the
Indenture and certain past Defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued
upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note. 

As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not have the right to institute any proceeding
with respect to the Indenture, or for the appointment of a receiver or trustee, or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Note,
the Holders of not less than 25% in principal amount of the Notes at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee indemnity
satisfactory thereto, and the Trustee shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity, and shall not have received from the Holders of a majority in principal amount of
Notes at the time Outstanding a direction inconsistent with such request. The foregoing shall not apply to any suit instituted by the Holder of this Note for the enforcement of any payment of the principal hereof, or interest hereon, the Fundamental
Change Repurchase Price or Redemption Price, and the amount of cash, the number of shares of Common Stock or the combination thereof, as the case may be, due upon conversion of this Note or after the respective due dates expressed in the Indenture.

 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 of (including the Fundamental Change Repurchase Price or Redemption Price), interest on and the amount of cash, a number of shares of Common Stock or
a combination of cash and shares of Common Stock, if any, as the case may be, due upon conversion of this Note at the time, place and rate, and in the coin and currency herein prescribed.
