the Trustee, the Note Registrar or any co-registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and duly executed, by the Holder
thereof or its attorney-in-fact duly authorized in writing. 

No service charge shall be charged by the Company, the Trustee or the Notes Registrar to the Holder for any exchange or registration of
transfer of Notes, but the Holder may be required by the Company, the Trustee, the Notes Registrar or otherwise to pay a sum sufficient to cover any tax, assessments or other governmental charges that may be imposed in connection therewith as a
result of the name of the Holder of the new Notes issued upon such exchange or registration of transfer of Notes being different from the name of the Holder of the old Notes presented or surrendered for such exchange or registration of transfer.

 None of the Company, the Trustee, the Note Registrar or any co-registrar shall be required to
exchange or register a transfer of any Notes surrendered for conversion or repurchase except for any portion of that Note that is not being repurchased or converted, as the case may be. 

All Notes issued upon any registration of transfer or exchange of Notes in accordance with this Indenture shall be the valid obligations of
the Company, evidencing the same debt, and entitled to the same benefits under this Indenture as the Notes surrendered upon such registration of transfer or exchange. For greater certainty, all Notes issued upon any registration of transfer or
exchange of Notes shall be issued as evidence of the same continuing indebtedness of the Company under this Indenture and in no circumstances is the Company obligated under the Indenture to repay the principal amount of the exchanged Notes by virtue
of the registration of a transfer or exchange. 
 (b)    So long as the Notes are eligible for book-entry settlement
with the Depositary, unless otherwise required by law or except as provided in Section 2.05(c), all Notes shall be represented by one or more Notes in global form (each, a “Global Note”) registered in the name of the Depositary
or the nominee of the Depositary. The transfer and exchange of beneficial interests in a Global Note that does not involve the issuance of a Physical Note shall be effected 

  
 17 












 
through the Depositary (but not the Trustee or the Custodian) in accordance with this Indenture (including the restrictions on transfer set forth herein) and the procedures of the Depositary
therefor. Beneficial interests in the Global Note shall be held only in minimum denominations of $1,000 and greater integral multiples of $1,000. Members of, or participants in, the Depositary (“Agent Members”) shall have no rights
under this Indenture with respect to any Global Note held on their behalf by the Depositary, or the Trustee as its custodian, or under the Global Note, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the
Trustee as the absolute owner of the Global Note for all purposes whatsoever. 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
certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of any Holder. 

(c)    Every Note that bears or is required under this Section 2.05(c) to bear the Restrictive Legend (together with
any Common Stock issued upon conversion of the Notes and required to bear a similar legend, the “Restricted Securities”) shall be subject to the restrictions on transfer set forth in this Section 2.05(c) (including the
restrictions set forth in the Restrictive Legend), and the Holder of each such Restricted Security, by such Holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in this Section 2.05(c), the term
“transfer” encompasses any sale, pledge, transfer or other disposition whatsoever of any Restricted Security. 
 Until the
date (the “Resale Restriction Termination Date”) that is the later of (1) the date that is one year after the last date of original issuance of the Notes (including, if applicable, through exercise by the Initial Purchasers of
their option to purchase additional Notes pursuant to the Purchase Agreement) and (2) such later date, if any, as may be required by applicable laws, any certificate evidencing such Note (and all securities issued in exchange therefor or
substitution thereof, and all shares of Common Stock, if any, issued upon conversion thereof, if applicable) shall bear a legend (the “Restrictive Legend”) in substantially the following form (unless such Note or shares of Common
Stock, if any, have been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer, pursuant to the exemption from
registration provided by Rule 144 or any similar provision then in force under the Securities Act, or unless otherwise agreed by the Company in writing, with written notice thereof to the Trustee): 

THE SALE OF THIS NOTE HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND,
ACCORDINGLY, PRIOR TO THE RESALE RESTRICTION TERMINATION DATE (AS DEFINED BELOW), THIS NOTE AND ANY COMMON STOCK ISSUABLE UPON CONVERSION OF THIS NOTE MAY NOT BE OFFERED, RESOLD, OR OTHERWISE TRANSFERRED, EXCEPT: 

(A)    TO THE GREENBRIER COMPANIES, INC. (THE “COMPANY”) OR ANY SUBSIDIARY THEREOF; 

  
 18 












 (B)    PURSUANT TO, AND IN ACCORDANCE WITH, A REGISTRATION STATEMENT
THAT IS EFFECTIVE UNDER THE SECURITIES ACT AT THE TIME OF SUCH TRANSFER; 
 (C)    TO A PERSON THAT YOU REASONABLY
BELIEVE TO BE A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT; OR 
 (D)    UNDER
ANY OTHER AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT (INCLUDING, IF AVAILABLE, THE EXEMPTION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT). 

THE “RESALE RESTRICTION TERMINATION DATE” MEANS THE LATER OF: (1) THE DATE THAT IS ONE YEAR AFTER THE DATE OF LAST ORIGINAL
ISSUANCE OF THE NOTES (INCLUDING THE LAST DATE OF ISSUANCE OF ADDITIONAL NOTES PURSUANT TO THE EXERCISE OF THE INITIAL PURCHASERS’ OPTION TO PURCHASE ADDITIONAL NOTES) OR SUCH SHORTER PERIOD OF TIME PERMITTED BY RULE 144 UNDER THE SECURITIES
ACT OR ANY SUCCESSOR PROVISION THERETO; AND (2) THE DATE ON WHICH WE HAVE INSTRUCTED THE TRUSTEE THAT THE FOREGOING RESTRICTIONS WILL NO LONGER APPLY IN ACCORDANCE WITH THE PROCEDURES DESCRIBED IN THE INDENTURE. 

WITH RESPECT TO ANY TRANSFER PURSUANT TO THE FOREGOING CLAUSE (D), PRIOR TO THE RESALE RESTRICTION TERMINATION DATE, THE COMPANY AND THE
TRUSTEE RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS THEY MAY REASONABLY REQUIRE AND MAY RELY UPON TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A
TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 
 Any Common Stock issued upon conversion of any Note
prior to the Resale Restriction Termination Date shall bear a legend in form and substance similar to the Restrictive Legend. 
 No transfer
of any Note prior to the Resale Restriction Termination Date will be registered by the Note Registrar unless the applicable box on the Form of Assignment and Transfer has been checked. 

Notwithstanding anything to the contrary contained in this Indenture or a Note (except for Section 2.05(d)), after the Resale Restriction
Termination Date with respect to a Note, such Note (or security issued in exchange or substitution therefor) as to which such restrictions on transfer shall have expired in accordance with their terms may, upon surrender of such Note for exchange to
the Note Registrar in accordance with the provisions of this Section 2.05, be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the Restrictive Legend and the CUSIP number for which shall be
the applicable unrestricted CUSIP number. 

  
 19 












 Notwithstanding any other provisions of this Indenture (other than the provisions set forth
in this Section 2.05(c)), a Global Note may not be transferred as a whole or in part except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the
Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. 
 The Depositary shall be a clearing
agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global Note. Initially, the Global Notes shall be issued to the Depositary,
registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for DTC. 
 If
(i) the Depositary notifies the Company at any time that the Depositary is unwilling or unable to continue as depositary for the Global Notes and a successor depositary is not appointed within 90 days, (ii) the Depositary ceases to be
registered as a clearing agency under the Exchange Act and a successor depositary is not appointed within 90 days or (iii) an Event of Default with respect to the Notes has occurred and is continuing, in each case, upon the request of the
beneficial owner of the Notes, the Company shall execute, and the Trustee, upon receipt of an Officers’ Certificate and a Company Order for the authentication and delivery of Notes, shall authenticate and deliver Physical Notes to each such
beneficial owner of the related Notes (or a portion thereof) in an aggregate principal amount equal to the principal amount of such Global Note, in exchange for such Global Note, and upon delivery of the Global Note to the Trustee such Global Note
shall be canceled. 
 Physical Notes issued in exchange for all or a part of the Global Note pursuant to this Section 2.05(c) shall be
registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee in writing. Upon execution and authentication, the Trustee
shall deliver such Physical Notes to the Persons in whose names such Notes are so registered. The holder shall provide to the Trustee in its capacity as Paying Agent such tax forms, as applicable, and related supporting documentation in order to
comply with its withholding obligations as required under applicable law and the Trustee shall have no liability related to tax withholding. 

At such time as all interests in a Global Note have been converted, canceled, repurchased or transferred, such Global Note shall be, upon
receipt thereof, canceled by the Trustee in accordance with standing procedures and instructions existing between the Depositary and the Custodian. At any time prior to such cancellation, if any interest in a Global Note is exchanged for Physical
Notes, converted, canceled, repurchased or transferred to a transferee who receives Physical Notes therefor or any Physical Note is exchanged or transferred for part of such Global Note, the principal amount of such Global Note shall, in accordance
with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the
direction of the Trustee, to reflect such reduction or increase. 
 None of the Company, the Trustee, nor any agent of the Company or the
Trustee shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such
beneficial ownership interests. 

  
 20 












 (d)    The Company may cause the removal of the Restrictive Legend from
any Global Note at any time on or after the Resale Restriction Termination Date by: (i) instructing the Trustee in writing to remove the Restrictive Legend from such Global Note; (ii) providing to the Trustee and the Depositary written
notice to change the CUSIP number for the Notes to the applicable unrestricted CUSIP number; and (iii) complying with any Applicable Procedures for delegending or otherwise exchanging such Global Note for a Global Note not bearing the
Restrictive Legend (including DTC’s mandatory exchange process, if applicable); whereupon the Restrictive Legend shall be deemed removed from any Global Notes and there shall be no requirement that any Common Stock into which such Global Notes
are convertible bear a legend in form and substance similar to the Restrictive Legend, in each case without any further action on the part of the Holders. 

(e)    The Trustee shall 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 participants or beneficial owners of interests in any Global
Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial
compliance as to form with the express requirements hereof. 
 (f)    The Company shall not, and shall use commercially
reasonable efforts to not permit any of its “affiliates” within the meaning of Rule 144, to resell any of the Notes that constitute “restricted securities” under Rule 144 that have been reacquired by them. The notes will be
issued with a restricted CUSIP number. 
 Section 2.06.    Mutilated, Destroyed, Lost or Stolen Notes.
In case any Note shall become mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon a Company Order the Trustee or an authenticating agent appointed by the Trustee shall authenticate and deliver, a new
Note, bearing a number not contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note shall
furnish to the Company, to the Trustee and, if applicable, to the authenticating agent, such security or indemnity as may be required by them to save each of them harmless from any loss, liability, cost or expense caused by or connected with such
substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to the authenticating agent, evidence to their satisfaction of the destruction, loss or theft of such
Note and of the ownership thereof. 
 The Trustee or the authenticating agent, if applicable, may authenticate any such substituted Note and
deliver the same upon the receipt of such security or indemnity as the Trustee, the Company and, if applicable, the authenticating agent may require. Upon the issuance of any substitute Note, the Company or the Trustee may require the payment by the
Holder of a sum sufficient to cover any tax, assessment or other governmental charge that may 

  
 21 












 
be imposed in relation thereto and any other expenses connected therewith. In case any Note that has matured or is about to mature or has been tendered for repurchase upon a Fundamental Change or
is about to be converted shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same
(without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to the authenticating agent, such security or
indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, evidence satisfactory to the Company, the
Trustee and, if applicable, any Paying Agent or Conversion Agent evidence of their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof. 

Every substitute Note issued pursuant to the provisions of this Section 2.06 by virtue of the fact that any Note is destroyed, lost or
stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set
forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that the foregoing provisions are exclusive with
respect to the replacement, payment, conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies, notwithstanding any law or statute existing or hereafter enacted to the contrary
with respect to the replacement, payment or conversion of negotiable instruments or other securities without their surrender. 
 For greater
certainty, every substitute Note issued pursuant to the provisions of this Section 2.06 by virtue of the fact that any Note is mutilated, destroyed, lost or stolen shall be issued as evidence of the same continuing indebtedness of the Company
under this Indenture and in no circumstances is the Company obligated under the Indenture to repay the principal amount of the substituted Note by virtue of such mutilation, destruction or loss. 

Section 2.07.    Temporary Notes. Pending the preparation of Physical Notes, the Company may execute
and the Trustee or an authenticating agent appointed by the Trustee shall, upon written request of the Company, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized denomination, and
substantially in the form of the Physical Notes but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be executed by the Company and
authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Physical Notes. Without unreasonable delay, the Company shall execute and deliver to the
Trustee or such authenticating agent Physical Notes (other than any Global Note) and thereupon any or all temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each office or agency maintained by the Company
pursuant to Section 4.05 and the Trustee or such authenticating agent shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Physical Notes. Such exchange shall be made by the Company at its
own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Physical Notes authenticated and delivered
hereunder. 

  
 22 












 For greater certainty, each Note issued pursuant to the provisions of this Section 2.07
in exchange for a temporary Note shall be issued as evidence of the same continuing indebtedness of the Company under this Indenture and in no circumstances is the Company obligated under the Indenture to repay the principal amount of the temporary
Note by virtue of the exchange. 
 Section 2.08.    Cancellation of Notes Paid, Etc. All Notes surrendered
for the purpose of payment, repurchase, conversion, exchange or registration of transfer, shall, if surrendered to the Company or any Paying Agent or any Note Registrar or any Conversion Agent, be surrendered to the Trustee and promptly canceled by
it, or, if surrendered to the Trustee, shall be promptly canceled by it, and no Notes shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of canceled Notes in accordance
with its customary procedures and, after such cancellation, shall deliver a written confirmation of such cancellation to the Company, at the Company’s written request. If the Company shall acquire any of the Notes, such acquisition shall not
operate as satisfaction of the indebtedness represented by such Notes unless and until the same are delivered to the Trustee for cancellation. 

Section 2.09.    CUSIP and ISIN Numbers. The Company in issuing the Notes may use “CUSIP” and
“ISIN” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” and “ISIN” numbers in all notices issued to Holders of the Notes as a convenience to such Holders; provided that any such
notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or on such notice and that reliance may be placed only on the other identification numbers printed on the Notes. The Company shall
promptly notify the Trustee in writing of any change in the “CUSIP” or “ISIN” numbers. 
 Any Notes that are, when
issued, Restricted Securities shall be issued with a restricted CUSIP number. Until such time as the Restrictive Legend is removed from such Notes pursuant to the terms of this Indenture, the restricted CUSIP shall be the CUSIP number for such
Notes. After the Company causes the removal of the Restrictive Legend from such Notes the CUSIP number for such Notes shall be an unrestricted CUSIP number. 

Section 2.10.    Additional Notes; Purchases. The Company may, without the consent of the Holders of the Notes
and notwithstanding Section 2.01, issue additional Notes hereunder with the same terms and with the same CUSIP and ISIN number as the Notes initially issued hereunder in an unlimited aggregate principal amount, which shall form the same series
with the Notes initially issued hereunder; provided that no such additional Notes may be issued unless they are fungible with the Notes initially issued hereunder for U.S. federal income tax purposes. Prior to the issuance of any such
additional Notes, the Company shall deliver to the Trustee a Company Order, an Opinion of Counsel (with respect to the enforceability of such additional notes) and an Officers’ Certificate to the effect that such issuance of additional Notes
complies with the provisions of the Indenture (including this Section 2.10). In addition, the Company may, to the extent permitted by law, directly or indirectly (regardless of whether such Notes are surrendered to the Company), from time to
time purchase the Notes in open market purchases or negotiated transactions without prior notice to Holders. The Company shall cause any Notes so repurchased (other than Notes purchased pursuant to cash-settled swaps or other derivatives) to be
surrendered to the Trustee for cancellation in accordance with Section 2.08 and any Notes so repurchased by the Company shall be deemed to be no longer Outstanding under this Indenture. 

  
 23 












 ARTICLE 3 

SATISFACTION AND DISCHARGE 

Section 3.01.    Satisfaction and Discharge. This Indenture shall upon request of the Company contained in an
Officers’ Certificate cease to be of further effect, and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when (a) (i) the Company delivers to the
Trustee all Outstanding Notes (other than Notes replaced pursuant to Section 2.06) for cancellation; or (ii) the Company has irrevocably deposited with the Trustee or delivered to Holders of Notes, as applicable, after the Notes have
become due and payable, whether at the Maturity Date or any Fundamental Change Repurchase Date, or upon conversion or otherwise, cash and/or (in the case of conversion) shares of Common Stock (together with cash in lieu of fractional shares), as
applicable, sufficient to pay all of the Outstanding Notes and all other sums payable under this Indenture by the Company; and (b) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating
that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee
under Section 7.06 shall survive such satisfaction and discharge. 
 Section 3.02.    Deposited Monies
To Be Held In Trust. Subject to Section 3.03 hereof, all monies deposited with the Trustee pursuant to Section 3.01 hereof shall be held in trust and applied by it to the payment, either directly or through any Paying
Agent (including the Company if acting as its own Paying Agent), to the Holders for the payment of which such monies have been deposited with the Trustee, of all sums due and to become due thereon for principal and interest. All monies deposited
with the Trustee pursuant to Section 3.01 hereof (and held by it or any Paying Agent) for the payment of Notes subsequently converted shall be returned to the Company upon written request of the Company. 

Section 3.03.    Return Of Unclaimed Monies. Subject to applicable escheatment laws, the Trustee
and the Paying Agent (if other than the Trustee) shall pay to the Company upon written request any money held by them for the payment of principal of, or accrued and unpaid interest on, the Notes that remains unclaimed for two years after the date
upon which such payment shall have become due. After payment to the Company by the Trustee or Paying Agent (if other than the Trustee), all liability of the Trustee and the Paying Agent (if other than the Trustee) with respect to such money shall
cease, and Holders entitled to the money must look to the Company for payment as general creditors, subject to applicable law. 
 ARTICLE 4

 PARTICULAR COVENANTS OF THE COMPANY 

Section 4.01.    Payment of Principal and Interest. (a) The Company shall promptly make all payments in
respect of the Notes on the dates and in the manner provided in the Notes and 

  
 24 












 
this Indenture. A payment of principal or interest shall be considered paid on the date it is due if the Paying Agent holds by 11:00 a.m. (New York City time) on that date money or securities,
deposited by or on behalf of the Company sufficient to make the payment. The Company shall, to the fullest extent permitted by law, pay interest in immediately available funds on any overdue principal amount and interest at the annual rate borne by
the Notes compounded semiannually, which interest shall accrue from the date such overdue amount was originally due to the date payment of such amount, including interest thereon, has been made or duly provided for. All such interest shall be
payable on demand. With respect to any certificated Notes, presentation is due at maturity. 
 (b)    Payment of the
principal of and interest, if any, on the Notes shall be made at the office or agency of the Company maintained for that purpose, which shall initially be at the Trustee’s Corporate Trust Office, in such immediately available coin or currency
of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that, subject to Section 2.03, the Company may pay principal and interest in respect of any
Physical Note by check or wire transfer payable in such money. Notwithstanding the foregoing, so long as the Notes are registered in the name of a Depositary or its nominee, all payments thereon shall be made by wire transfer of immediately
available funds to the account of the Depositary or its nominee. 
 Section 4.02.    Corporate Existence.
Subject to Article 10 hereof, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and rights (charter and statutory); provided, however, that the Company
shall not be required to preserve any such right or franchise if the Company determines that the preservation thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any
material respect to the Holders. 
 Section 4.03.    Rule 144A Information Requirement and Reports.
(a) At any time the Company is not subject to Sections 13 or 15(d) of the Exchange Act, the Company shall, so long as any of the Notes or any shares of Common Stock issuable upon conversion thereof shall, at such time, constitute
“restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, upon written request, provide to any Holder, beneficial owner or prospective purchaser of such Notes or any shares of Common Stock issued upon
conversion of such Notes, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of such Notes or shares of Common Stock pursuant to Rule 144A under the Securities Act. 

(b)    The Company shall furnish to the Trustee within 15 calendar days after the Company is required to file any
documents or reports with the Commission pursuant to Sections 13 or 15(d) of the Exchange Act (giving effect to all applicable grace periods provided under the Exchange Act including that provided by Rule
12b-25 under the Exchange Act) copies of such documents or reports. Any such document or report that the Company files with the Commission through the Commission’s EDGAR system shall be deemed furnished
to the Trustee for purposes of this Section 4.03(b) at the time such documents are filed or furnished via the Commission’s EDGAR system; provided that the Trustee shall have no responsibility for determining whether such filing has
taken place, nor shall the Trustee have any liability for the 

  
 25 












 
timeliness or content of any filing or report hereunder. Delivery of reports, information and documents to the Trustee is for informational purposes only and its receipt of such reports shall not
constitute constructive notice of any information contained therein or determinable from information contained therein, including our compliance with any of our covenants under the indenture or the notes (as to which the Trustee is entitled to rely
exclusively on officers’ certificates). The Trustee shall not be obligated to monitor or confirm, on a continuing basis or otherwise, the Company’s compliance with the covenants or with respect to any reports or other documents filed with
the SEC or EDGAR or any website under the indenture, or participate in any conference calls. 

Section 4.04.    Compliance Certificate. The Company shall deliver to the Trustee, within 120 days after the
end of each fiscal year of the Company an Officers’ Certificate stating whether or not, to the knowledge of such officer, the Company is in default in the performance and observance of any of the terms, provisions and conditions of this
Indenture and, if the Company shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge. Within five Business Days of an Officer of the Company coming to have actual knowledge of a Default
or Event of Default, regardless of the date, the Company shall deliver an Officers’ Certificate to the Trustee specifying such Default or Event of Default and the nature and status thereof (including any actions taken to cure such default).

 Section 4.05.    Maintenance of Office or Agency. So long as any Notes remain Outstanding, the Company
agrees to maintain an office or agency with respect to such Notes and at such other location or locations as may be designated as provided in this Section 4.05, where (i) Notes may be presented for conversion (the Person accepting such
conversions being the “Conversion Agent”), (ii) Notes may be presented for payment (whether upon repurchase, at the Maturity Date, upon acceleration or otherwise) (the Person accepting such presentments being the “Paying
Agent”), (iii) Notes may be presented as herein above authorized for registration of transfer and exchange and (iv) notices and demands to or upon the Company in respect of the Notes and this Indenture may be given or served, such
designation to continue with respect to such office or agency until the Company shall, by written notice signed by any two officers authorized to sign an Officers’ Certificate and delivered to the Trustee, designate some other office or agency
for such purposes or any of them. 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, notices and demands may be made or served at
the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations, notices and demands; provided, however, that the Trustee shall not be deemed an agent of the Company for service
of legal process. The Company initially appoints the Corporate Trust Office of the Trustee as Conversion Agent and Paying Agent with respect to the Notes. 

Section 4.06.    Paying Agents. (a) If the Company shall appoint one or more Paying Agents for the Notes,
other than the Trustee, the Company shall cause each such Paying Agent to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section 4.06: 

(i)    that it shall hold all sums held by it as agent for the payment of the principal of or interest on
the Notes (whether such sums have been paid to it by the Company or by any other obligor of such Notes) in trust for the benefit of the Persons entitled thereto; 

  
 26 












 (ii)    that it shall give the Trustee written notice of
any failure by the Company to make any payment of the principal of or interest on the Notes when the same shall be due and payable; 

(iii)    that it shall, at any time during the continuance of any failure referred to in the preceding
paragraph (a)(ii) above, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent; and 

(iv)    that it shall perform all other duties of a Paying Agent as set forth in this Indenture. 

(b)    If the Company shall act as its own Paying Agent with respect to any Notes, it shall on or before each due date of
the principal of or interest on the Notes, set aside, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay such principal or interest so becoming due on Notes until such sums shall be paid to such
Persons or otherwise disposed of as herein provided and shall promptly notify the Trustee in writing of such action, or any failure to take such action. The Trustee shall have no liability or responsibility for the action or inaction of any Paying
Agent (that is not the Trustee). 
 (c)    Notwithstanding anything in this Section 4.06 to the contrary,
(i) the agreement to hold sums in trust as provided in this Section 4.06 is subject to the provisions of Section 3.02 and Section 3.03 and (ii) the Company may at any time, for the purpose of obtaining the satisfaction and
discharge of this Indenture or for any other purpose, pay, or direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same terms and conditions as those
upon which such sums were held by the Company or such Paying Agent; 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 money.

 Section 4.07.    Appointment to Fill Vacancy in Office of Trustee. The Company, whenever necessary to
avoid or fill a vacancy in the office of Trustee, shall appoint, in the manner provided in Section 7.09, a Trustee, so that there shall at all times be a Trustee hereunder. 

Section 4.08.    Certain Reports. The Company and the Holders shall reasonably cooperate with the Trustee and
shall provide the Trustee with reasonable access to, and copies of, such documents or information in their respective possession regarding the Trustee’s compliance with any cost basis reporting obligations imposed on it by a governmental
authority in connection with certain transfers or exchanges of Notes.

Section 6.02.    Acceleration of Maturity; Rescission and Annulment. If an Event of Default with respect to
Outstanding Notes (other than an Event of Default specified Section 6.01(h) or Section 6.01(i) hereof in respect of the Company) occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the
then-Outstanding Notes, by written notice to the Company (and to the Trustee if given by the holders), may declare the Notes due and payable at their principal amount plus any accrued and unpaid interest, and thereupon the Trustee may, at its
discretion, proceed to protect and enforce the rights of the Holders by the appropriate judicial proceedings. Such declaration may be rescinded and annulled with the written consent of the Holders of a majority in aggregate principal amount of the
then-Outstanding Notes, subject to the provisions of this Indenture. 
 If an Event of Default specified in Section 6.01(h) or
Section 6.01(i) hereof occurs and is continuing, then all unpaid principal of, and accrued and unpaid interest on, the Outstanding Notes shall become immediately due and payable, without any declaration or other act on the part of the Trustee
or any Holder. 
 Notwithstanding the foregoing, at the election of the Company, the sole remedy for an Event of Default specified in
Section 6.01(f) relating to the failure by the Company to comply with its reporting obligations under Section 4.03 shall (i) for the first 90 days after the occurrence of such an Event of Default, consist exclusively of the right to
receive special interest on Notes (the “Special Interest”) at an annual rate equal to 0.25% per annum of the principal amount of the Outstanding Notes, and (ii) for the next 90 days after the expiration of such 90-day period, consist exclusively of the right to receive Special Interest on the Notes at an annual rate equal to 0.50% per annum of the principal amount of the Outstanding Notes. 

The Special Interest shall be paid semiannually in arrears, with the first semiannual payment due on the first Interest Payment Date following
the date on which the Special Interest began to accrue on any Notes. The Special Interest shall accrue on all Outstanding Notes from, and including, the date on which an Event of Default relating to a failure to comply with the reporting obligations
under Section 4.03 first occurs to, but not including, the 180th day thereafter (or such earlier date on which the Event of Default relating to such reporting obligations shall have been cured or waived). On such 180th day (or earlier, if such
Event of Default is cured or waived pursuant to Section 6.04 prior to such 180th day), such Special Interest will cease to accrue and, if such Event of Default relating to such reporting obligations has not been cured or waived prior to such
180th day, the Notes shall be subject to acceleration as provided above in this Section 6.02. The provisions described in this paragraph shall not affect the rights of the Holders in the event of the occurrence of any other Event of Default. In
the event the Company does not elect to pay Special Interest upon an Event of Default in accordance with this paragraph, the Notes will be subject to acceleration as provided in this Section 6.02. If the Company elects to pay Special Interest
as the sole remedy for an Event of Default specified in Section 6.01(f) relating to the failure by the Company to comply with its obligations under Section 4.03, the Company shall notify in writing, in the manner provided for


  
 30 












 
in Section 18.03, the Holders and the Trustee and Paying Agent (if other than the Trustee) of such election at any time on or before the close of business on the date on which such Event of
Default first occurs. If the Company fails to timely give such notice, the Notes shall be subject to acceleration as provided in this Section 6.02. 

The Holders of a majority in aggregate principal amount of the then-Outstanding Notes by written notice to the Trustee may rescind and annul
an acceleration and its consequences if: 
 (1)    all existing Events of Default, other than the nonpayment of
principal (including the Fundamental Change Repurchase Price, if applicable) of or interest on the Notes which has become due solely because of the acceleration, have been remedied, cured or waived; and 

(2)    the rescission would not conflict with any judgment or decree of a court of competent jurisdiction; 

provided, however, that in the event such declaration of acceleration has been made based on the existence of an Event of Default under
Section 6.01(g) hereof and such Event of Default has been remedied, cured or waived in accordance with Section 6.01(g) hereof, then, without any further action by the Holders, such declaration of acceleration shall be rescinded
automatically and the consequences of such declaration shall be annulled. No such rescission or annulment shall affect any subsequent Default or impair any right consequent thereon. 

Section 6.03.    Other Remedies. If an Event of Default with respect to Outstanding Notes occurs and is
continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of principal of, or interest on, the Notes or to enforce the performance of any provision of the Notes. 

Section 6.04.    Waiver of Past Defaults. The Holders, either (a) through the written consent of not less
than a majority in aggregate principal amount of the Notes then Outstanding or (b) by the adoption of a resolution, at a meeting of Holders of the Notes then Outstanding at which a quorum is present, by the Holders of at least a majority in
aggregate principal amount of the Outstanding Notes represented at such meeting, may, on behalf of the Holders of all of the Notes, waive an existing Default or Event of Default, except a Default or Event of Default: 

(1)    in the payment of the principal of (including Fundamental Change Repurchase Price, if applicable), or interest on,
any Note; 
 (2)    in respect of the right to convert any Note in accordance with Article 13; or 

(3)    in respect of the covenants or provisions hereof which, under Section 9.02 hereof, cannot be modified or
amended without the consent of the Holder of each Outstanding Note affected. 
 Upon any such waiver, such Default shall cease to exist, and
any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; provided, however, that no such waiver shall extend to any subsequent or other Default or impair any right consequent
thereon. 

  
 31 












 Section 6.05.    Control by Majority. The Holders, either
(a) through the written consent of not less than a majority in aggregate principal amount of the Notes then Outstanding, or (b) by the adoption of a resolution, at a meeting of Holders of the Notes then Outstanding at which a quorum is
present, by the Holders of at least a majority in aggregate principal amount of the Outstanding Notes represented at such meeting, shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the
Trustee or exercising any trust or power conferred on the Trustee, subject to the provisions of this Indenture. However, the Trustee may refuse to follow any direction that: 

(a)    conflicts with any law or with this Indenture; 

(b)    the Trustee determines may be unduly prejudicial to the rights of the Holders not joining therein; or 

(c)    in the Trustee’s reasonable judgment may expose the Trustee to personal liability. 

The Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. 

Section 6.06.    Limitation On Suit. No Holder of any Note may pursue any remedy with respect to
this Indenture or the Notes (including instituting any proceeding, judicial or otherwise, with respect to this Indenture or for the appointment of a receiver or trustee), except, in the case of a Default or Event of Default in the payment of the
principal of (including the Fundamental Change Repurchase Price, if applicable), or interest on, the Notes or Default in the payment or delivery of the consideration due upon conversion of Notes, unless: 

(a)    such Holder has previously given written notice to the Trustee of an Event of Default that is continuing; 

(b)    the Holders of at least 25% in aggregate principal amount of the Notes then Outstanding shall have made a written
request to the Trustee to pursue the remedy; 
 (c)    such Holder or Holders have offered the Trustee security or
indemnity satisfactory to the Trustee against any loss, costs, liabilities, claims or expenses incurred in complying with such request; 

(d)    the Trustee does not, within 60 days after receipt of the request and offer of indemnity, receive an inconsistent
direction from the Holders of a majority in principal amount of the Notes; and 
 (e)    the Trustee has failed to
comply with the request for 60 days after the receipt of such request and an offer of indemnity. 
 A Holder of Notes may not use this
Indenture to prejudice the rights of another Holder of Notes or to obtain a preference or priority over another Holder of Notes (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or
forbearances are unduly prejudicial to such Holders). 

  
 32 












 Section 6.07.    Unconditional Rights of Holders to Receive
Payment and to Convert. In addition to the other rights and remedies set forth in this Article 6, the following shall apply with respect to the Notes under this Indenture. 

Notwithstanding any other provision in this Indenture, the Holder of any Note shall have the right, which is absolute and unconditional, to
receive payment of the principal amount (including the Fundamental Change Repurchase Price, if applicable), interest and the Make-Whole Fundamental Change Premium, if any, in respect of the Notes held by such Holder, on or after the respective due
dates expressed in the Notes and this Indenture, and to convert such Note in accordance with Article 13, and to bring suit for the enforcement of any such payment on or after such respective due dates or for the right to convert in accordance with
Article 13, and shall not be impaired or affected without the consent of such Holder. 

Section 6.08.    Collection of Indebtedness and Suits For Enforcement By the Trustee. The
Company covenants that if an Event of Default occurs under Section 6.01(a) or Section 6.01(b), then the Company shall, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Notes, the whole amount then due and
payable (as expressed therein or as a result of any acceleration effected pursuant to Section 6.02 hereof) on such Notes for principal (including the Fundamental Change Repurchase Price, if applicable) and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue principal (including the Fundamental Change Repurchase Price, if applicable) and on any overdue interest, in each case at the rate borne by the Notes from the required
payment date, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

 If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company and collect the moneys adjudged or decreed to be payable in the
manner provided by law out of the property of the Company, wherever situated. 
 If an Event of Default occurs and is continuing, the
Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Notes by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the
specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. 

Section 6.09.    Trustee May File Proofs of Claim. In case of the pendency of any receivership, insolvency,
liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or the property of the Company or its creditors, the Trustee (irrespective of whether the principal of the Notes
(including the Fundamental Change Repurchase Price, if applicable) shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of
overdue principal or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise, (1) to file and prove a claim for the whole amount of principal (including the Fundamental Change


  
 33 












 
Repurchase Price, if applicable) and interest owing and unpaid in respect of the Notes and to file such other papers or documents as may be necessary or advisable in order to have the claims of
the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due to the Trustee hereunder) and of the Holders of Notes allowed in such judicial
proceeding, and (2) to collect and receive any moneys or other property payable or deliverable on any such claim and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in
any such judicial proceedings is hereby authorized by each Holder of Notes to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders of Notes, to pay to the Trustee
any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and any other amounts due the Trustee under this Indenture. 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 out of the estate in any such proceeding, shall be unpaid for any reason, payment of the same shall be secured by a lien on, and shall
be paid out of, any and all distributions, dividends, 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 contained herein shall be deemed to authorize the Trustee to authorize or consent to or accept, or adopt on behalf of any Holder of a
Note, any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder of a Note in any such proceeding. 

Section 6.10.    Restoration of Rights and Remedies. If the Trustee or any Holder of a Note 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 of Notes 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 2.06, no right or remedy conferred in this Indenture upon or reserved to the Trustee or to the Holders of Notes 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 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 Waiver. No delay or omission of the Trustee or of any Holder of any
Note 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 any acquiescence therein. Every right and remedy given by this Article 6 or by law
to the Trustee or to the Holders of Notes may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders of Notes, as the case may be. 

  
 34 












 Section 6.13.    Application of Money Collected. Any money
and property collected by the Trustee pursuant to this Article 6 shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money and property on account of principal (including the
Fundamental Change Repurchase Price, if applicable) or interest, upon presentation of the Notes and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: 

FIRST: To the payment of all amounts due the Trustee, in each of its capacities under this Indenture, including its agents and counsel; 

SECOND: To the payment of the amounts then due and unpaid for principal (including the Fundamental Change Repurchase Price, if applicable) of
and interest on the Notes in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Notes for principal (including the
Fundamental Change Repurchase Price, if applicable) and interest, respectively; and 
 THIRD: Any remaining amounts shall be repaid to the
Company. 
 Section 6.14.    Undertaking For Costs. All parties to this Indenture agree, and
each Holder of any Note by such Holder’s acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the
Trustee for any action taken, suffered or omitted by it as Trustee with respect to the Notes, 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; but 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 of any Note for the enforcement of the payment of the principal of (including the Fundamental Change Repurchase Price, if applicable), or interest on, any Note on or after the stated maturity expressed in such Note or on or
after a Fundamental Change Repurchase Date (in the case of Notes the Company is required to repurchase pursuant to Article 16) or for the enforcement of the right to convert any Note in accordance with Article 13. 

Section 6.15.    Waiver of Stay or Extension Laws. The Company covenants (to the extent that it may lawfully
do so) that it shall not at any time insist upon, or plead, or in any manner whatsoever claim to take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which 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 shall not hinder, delay or impede the execution of any power herein
granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted. 

  
 35 












 Section 6.16.    Notice of Default. If any Default or any
Event of Default occurs and is continuing and if such Default or Event of Default is actually known to a Responsible Officer of the Trustee, the Trustee shall within 90 days of the occurrence of a Default or Event of Default, mail to each Holder
notice of all uncured Defaults or Events of Default known to the Trustee, unless such Default or Event of Default has been cured; provided, however, that, except in the case of a default in the payment of the principal of (including
the Fundamental Change Repurchase Price, if applicable), or interest on, any Note, the Trustee shall be protected in withholding such notice if a Responsible Officer of the Trustee in good faith determines that the withholding of such notice is in
the interest of such Holders.

but in the case of any such certificates or opinions that by any provision 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 mathematical calculations or other facts stated therein);

good faith in accordance with the direction of the Holders of not less than a majority in principal amount of the Notes at the time Outstanding 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 with respect to the Notes; and

(d)    the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at
the request, order or direction of any of the Holders pursuant to the provisions of this Indenture, unless such Holders shall have offered the Trustee security or indemnity satisfactory to the Trustee against the costs, losses, claims, expenses and
liabilities that may be incurred therein or thereby;

 (j)    the Trustee shall not be required to give any bond or surety in respect of the performance of its powers and
duties hereunder;

any action that is not in accordance with applicable law; and 
 (o)    the Trustee shall not be responsible or liable
for the acts or omissions of any other party and may assume performance absent written notice or actual knowledge of a Responsible Officer to the contrary.

 (c)    The Company

misconduct (as finally adjudicated by a court of competent jurisdiction). 
 (d)    In addition and without prejudice to
the rights provided to the Trustee under any of the provisions of this Indenture, when the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 6.01(h) or Section 6.01(i), the expenses

survive the resignation or removal of the Trustee, the discharge of the Company’s obligations under Article 3 of this Indenture and/or the termination of this Indenture. 

Section 7.07.    Reliance on Officers’ Certificate and Opinions. Except as otherwise
provided in Section 7.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it reasonably necessary or desirable that a matter be proved or established prior to taking or suffering or omitting to take 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
Officers’ Certificate and Opinion of Counsel delivered to the Trustee and such certificate or opinion, in the absence of negligence or willful misconduct on the part of the Trustee, shall be full warrant to the Trustee for any action taken,
suffered or omitted to be taken by it under the provisions of this Indenture upon the faith thereof.

 Section 7.08.    Corporate Trustee Required; Eligibility.
There shall at all times be a Trustee with respect to the Notes issued hereunder which shall at all times be a corporation organized and doing business under the laws of the United States of America or any state or territory thereof or of the
District of Columbia, or a corporation or other Person that is eligible to act as such under the Trust Indenture Act and permitted to act as trustee by the Commission, authorized under such laws to exercise corporate trust powers, having a combined
capital and surplus of at least fifty million U.S. dollars ($50,000,000), and subject to supervision or examination by federal, state, territorial or District of Columbia authority. 

If such corporation or other Person publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid
supervising or examining authority, then for the purposes of this Section 7.08, the combined capital and surplus of such corporation or other Person shall be deemed to be its combined capital and surplus as set forth in its most recent report
of condition so published. The Company may not, nor may any Person directly or indirectly controlling, controlled by, or under common control with the Company, serve as Trustee. In case at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section 7.08, the Trustee shall resign immediately in the manner and with the effect specified in Section 7.09. 

Section 7.09.    Resignation and Removal; Appointment of Successor. 

(a)    The Trustee or any successor hereafter appointed may at any time resign with respect to the Notes by giving written
notice thereof to the Company. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee with respect to the Notes 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 within 30 days after the mailing of such notice of resignation,
the resigning Trustee, at the expense of the Company, may petition any court of competent jurisdiction for the appointment of a successor trustee with respect to the Notes, or any Holder who has been a bona fide Holder of Notes for at least six
months may 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 one of the following shall occur: 

(i)    the Trustee shall fail to comply with the provisions of Section 7.08 after written request
therefor by the Company or by any Holder who has been a bona fide Holder of Notes for at least six months; 

(ii)    the Trustee shall cease to be eligible in accordance with the provisions of Section 7.08 and
shall fail to resign after written request therefor by the Company or by any such Holder; or 

(iii)    the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or
commence a voluntary bankruptcy proceeding, or a receiver of the Trustee or of its property shall be appointed or consented to, or any public officer 

  
 41 












 
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 with respect to the Notes 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 any Holder who has been a bona fide Holder of Notes for at least six months may, on behalf of that Holder and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the
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 by so notifying the Trustee and the Company in writing and may nominate a successor Trustee that shall be deemed appointed as successor trustee unless within ten days after notice to the Company of such nomination the Company objects
thereto, in which case the Trustee so removed, at the expense of the Company, or any Holder, upon the terms and conditions and otherwise as in Section 7.09(a) provided, may petition 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 with
respect to the Notes pursuant to any of the provisions of this Section 7.09 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 7.10. 

Section 7.10.    Acceptance of Appointment By Successor. 

(a)    In case of the appointment hereunder of a successor trustee with respect to all Notes, every such successor trustee
so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor
trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the written request of the Company or the successor trustee, such retiring Trustee shall, upon
payment of its charges, execute and deliver an instrument transferring to such successor trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor trustee all property and money
held by such retiring Trustee hereunder. The trustee shall have no liability or responsibility for the action or inaction of any successor Trustee. 

(b)    In case of the appointment hereunder of a successor trustee with respect to some, but not all of the Notes, the
Company, the retiring Trustee and each successor trustee with respect to such Notes shall execute and deliver an indenture supplemental hereto wherein each successor trustee shall accept such appointment and which (i) shall contain such
provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Notes to which the appointment of such successor
trustee relates, (ii) shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Notes as to which the retiring Trustee is not
retiring shall continue to be vested in the retiring Trustee and (iii) shall add to or change any of the provisions 

  
 42 












 
of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such
supplemental indenture shall constitute such Trustees co-trustees of the same trust, that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder
administered by any other such Trustee and that no Trustee shall be responsible for any act or failure to act on the part of any other Trustee hereunder; and upon the execution and delivery of such supplemental indenture the resignation or removal
of the retiring Trustee shall become effective to the extent provided therein, such retiring Trustee shall with respect to the Notes to which the appointment of such successor trustee relates have no further responsibility for the exercise of rights
and powers or for the performance of the duties and obligations vested in the Trustee under this Indenture, and each such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee with respect to the Notes to which the appointment of such successor trustee relates; but, on the written request of the Company or any successor trustee, such retiring Trustee shall duly assign, transfer and deliver
to such successor trustee, to the extent contemplated by such supplemental indenture, the property and money held by such retiring Trustee hereunder with respect to the Notes to which the appointment of such successor trustee relates. 

(c)    Upon request of any such successor trustee, the Company shall execute any and all instruments for more fully and
certainly vesting in and confirming to such successor trustee all such rights, powers and trusts referred to in paragraph (a) or (b) of this Section 7.10, as the case may be. 

(d)    No successor trustee shall accept its appointment unless at the time of such acceptance such successor trustee
shall be qualified and eligible under this Article 7. 
 (e)    Upon acceptance of appointment by a successor trustee as
provided in this Section 7.10, the Company shall transmit notice of the succession of such trustee hereunder by mail, first-class postage prepaid, to the Holders, as their names and addresses appear upon the Note Register. If the Company fails
to transmit such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be transmitted at the expense of the Company. 

Section 7.11.    Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the
Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the
corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided that such corporation shall be qualified under the provisions of Section 7.08 and eligible under the provisions of Section 7.08,
without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding. In case any Notes shall have been authenticated, but not delivered, by the Trustee then in
office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Notes so authenticated with the same effect as if such successor Trustee had itself authenticated such Notes.

 ARTICLE 8 

CONCERNING THE HOLDERS 

Section 8.01.    Evidence of Action by Holders. Whenever in this Indenture it is provided that the
Holders of a majority or specified percentage in aggregate principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact
that at the time of taking any such action the Holders of such majority or specified percentage of such Notes have joined therein may be evidenced by any instrument or any number of instruments of similar tenor executed by such Holders of such Notes
in person or by agent or proxy appointed in writing. 
 If the Company shall solicit from the Holders any request, demand, authorization,
direction, notice, consent, waiver or other action, the Company may, at its option, as evidenced by an Officers’ Certificate, fix in advance a record date for such Notes for the determination of Holders entitled to give such request, demand,
authorization, direction, notice, consent, waiver or other action, but the Company shall have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other action may be
given before or after the 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 Outstanding Notes have
authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other action, and for that purpose the Outstanding Notes shall be computed as of the record date; provided, however, that
no such authorization, agreement or consent by such Holders on the 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. 

Section 8.02.    Proof of Execution by Holders. Subject to the provisions of Section 8.01, proof of the
execution of any instrument by a Holder (such proof will not require notarization) or his agent or proxy and proof of the holding by any Person of any of the Notes shall be sufficient if made in the following manner: 

(a)    The fact and date of the execution by any such Person of any instrument may be proved in any reasonable manner
acceptable to the Trustee. 
 (b)    The ownership of Notes shall be proved by the Note Register or by a certificate of
the Note Registrar thereof. 
 The Trustee may require such additional proof of any matter referred to in this Section 8.02 as it shall
deem necessary. 
 Section 8.03.    Who May be Deemed Owners. Prior to the due presentment for registration
of transfer of any Note, the Company, the Trustee, any Paying Agent and any Note Registrar may deem and treat the Person in whose name such Note shall be registered upon the books of the Note Registrar as the absolute owner of such Note (whether or
not such Note shall be overdue and notwithstanding any notice of ownership or writing thereon made by anyone other than the Note Registrar) for the purpose of receiving payment of or on account of the


  
 44 












 
principal of (including the Fundamental Change Repurchase Price, if applicable), and interest on, such Note and for all other purposes; and neither the Company nor the Trustee nor any Paying
Agent nor any Note Registrar shall be affected by any notice to the contrary. 
 Section 8.04.    Certain Notes
Owned by Company Disregarded. In determining whether the Holders of the requisite aggregate principal amount of Notes have concurred in any direction, consent or waiver under this Indenture, the Notes that are owned by the Company or any other
obligor on the Notes or by any Affiliate of the Company or any other obligor on the Notes shall be disregarded and deemed not to be Outstanding for the purpose of any such determination, except that for the purpose of determining whether the Trustee
shall be protected in relying on any such direction, consent or waiver, only Notes that a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded. The Notes so owned that have been pledged in good faith may be regarded
as Outstanding for the purposes of this Section 8.04, if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right so to act with respect to such Notes and that the pledgee is not a Person directly or indirectly
controlling or controlled by or under direct or indirect common control with the Company or any such other obligor. In case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the
Trustee. 
 Section 8.05.    Actions Binding on Future Holders. At any time prior to (but not after) the
evidencing to the Trustee, as provided in Section 8.01, of the taking of any action by the Holders of the majority or percentage in aggregate principal amount of the Notes specified in this Indenture in connection with such action, any Holder
of a Note that is shown by the evidence to be included in the Notes the Holders of which have consented to such action may, by filing written notice with the Trustee, and upon proof of holding as provided in Section 8.02, revoke such action so
far as concerns such Note. Except as aforesaid any such action taken by the Holder of any Note shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Note, and of any Note issued in exchange therefor, on
registration of transfer thereof or in place thereof, irrespective of whether or not any notation in regard thereto is made upon such Note. Any action taken by the Holders of the majority or percentage in aggregate principal amount of the Notes
specified in this Indenture in connection with such action shall be conclusively binding upon the Company, the Trustee and the Holders. 

ARTICLE 9

interests of the Holders of Notes in any material respect; provided further that any amendment made solely to conform the provisions of this Indenture to the description thereof set forth under the caption “Description of Notes” in
the Offering Memorandum shall be deemed not to adversely affect the interest of the Holders if the Company delivers an Officers’ Certificate to the Trustee certifying that such amendment is made solely to conform the provisions of this
Indenture; 
 (g)    adding guarantees with respect to the Notes; 

(h)    securing the Notes; 

(i)    to add or modify any other provisions which the Company may deem necessary or desirable and which shall not
adversely affect the interests of the Holders of Notes in any material respect;

Indenture and the form or terms of the Notes to the description thereof set forth under the caption “Description of Notes” in the Offering Memorandum; 

(k)    irrevocably elect a settlement method or a Specified Dollar Amount;

(m)    to comply with the applicable procedures of the Depositary. 

After an amendment, supplement or waiver under this Section 9.01 becomes effective, the Company or, at the written request of the
Company, the Trustee shall send to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect
the validity of any such amendment, supplement or waiver. 
 Section 9.02.    With Consent of Holders.
Except as provided below in this Section 9.02, this Indenture or the Notes may be amended or supplemented, and noncompliance by the Company in any particular instance with any provision of this Indenture or the Notes may be


  
 46 












 
waived, in each case (i) with the written consent of the Holders of at least a majority in aggregate principal amount of the Notes then Outstanding or (ii) by the adoption of a
resolution, at a meeting of Holders of the Notes then Outstanding at which a quorum is present, by the Holders of a majority in aggregate principal amount of the Outstanding Notes represented at such meeting. 

Without the written consent or the affirmative vote of each Holder of an affected Note, an amendment, supplement or waiver to this Indenture
or the Notes may not: 
 (a)    change the stated maturity of the principal of, or the time of payment of any
installment of interest on, any Note; 
 (b)    reduce the principal amount of any Note; 

(c)    reduce the interest rate or interest on any Note;

(j)    reduce the percentage in aggregate principal amount of the Outstanding Notes required for the adoption of a
resolution or the quorum required at any meeting of Holders of Notes at which a resolution is adopted. 
 It shall not be necessary for the
consent of Holders of Notes under this Section 9.02 to approve the particular form of any proposed modification, amendment or waiver, but it shall be sufficient if such act shall approve the substance thereof. 

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company, or, at the written request of the
Company, the Trustee, shall mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect
the validity of any such amendment, supplement or waiver.

execution of any supplemental indenture pursuant to the provisions of this Article 9 or Section 10.01 this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitations of rights,
obligations, duties and immunities under this Indenture of the Trustee, the Company and the Holders of Notes affected thereby shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and
amendments, and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes. 

Section 9.04.    Notes Affected by Supplemental Indentures. Notes affected by a supplemental indenture,
authenticated and delivered after the execution of such supplemental indenture pursuant to the provisions of this Article 9 or Section 10.01, may bear a notation in form approved by the Company as to any matter provided for in such supplemental
indenture; provided such form meets the requirements of any securities exchange upon which such Notes may be listed. If the Company shall so determine, new securities so modified as to conform, in the opinion of the Board of Directors, to any
modification of this Indenture contained in any such supplemental indenture may be prepared by the Company, authenticated by the Trustee and delivered in exchange for the Notes then Outstanding. 

Section 9.05.    Execution of Supplemental Indentures. Upon the written request of the Company, accompanied by
its Board Resolutions authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent of Holders required to consent thereto as aforesaid (if such consent is required pursuant to this
Article), the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the
Trustee may in its discretion but shall not be obligated to enter into such supplemental indenture. The Trustee, subject to the provisions of Section 7.01, shall receive and will be fully protected in conclusively relying upon an Officers’
Certificate and an Opinion of Counsel stating that any supplemental indenture executed pursuant to this Article is authorized or permitted by the terms of this Article 9 and constitutes a legal, valid and binding obligation, enforceable against the

Affiliates (an “Additional Interest Event”), the Company shall pay additional interest on the Notes (the “Additional Interest”). Such Additional Interest will accrue on the Notes at the rate of 0.25% per annum of
the principal amount of Notes Outstanding for each day during the first 90-day period (or portion thereof) for which an Additional Interest Event has occurred and is continuing, which rate shall increase by an
additional 0.25% per annum of the principal amount of the Notes, up to a maximum of 0.50% per annum of the principal amount of the Notes for each day thereafter for which an Additional Interest Event has occurred and is continuing. 

(b)    Unless: 

(i)    the Restrictive Legend on the Notes has been removed; or 

(ii)    the Notes are freely tradable pursuant to Rule 144 by Holders other than the Company’s
Affiliates (without restrictions pursuant to U.S. securities law), 
 on or after the 365th day after the last date of original issuance of the Notes, an
Additional Interest Event shall be deemed to have occurred and the Company shall pay Additional Interest on the Notes at an annual rate equal to 0.50% of the aggregate principal amount of the Notes Outstanding for each day until the Notes are freely
tradable as described above. 
 (c)    Notwithstanding the foregoing, the Company shall not be required to pay
Additional Interest on any date if (i) the Company has filed a shelf registration statement for the resale of the Notes and any shares of Common Stock issued upon conversion of the Notes, (ii) such shelf registration statement is effective
and usable by Holders of the Notes identified therein as selling securityholders for the resale of the Notes and any shares of Common Stock issued upon conversion of the Notes and (iii) such Holders may register the resale of their Notes under
such shelf registration statement on terms customary for the resale of convertible securities offered in reliance on Rule 144A. Under no circumstances will the combined rate of Additional Interest and Special Interest exceed 1.00% per annum. 

(d)    Additional Interest shall be payable in arrears on each Interest Payment Date following accrual in the same manner
as regular interest on the Notes. 

  
 50 












 (e)    If Additional interest is payable by the Company on the Notes,
the Company shall deliver to the Trustee an Officers’ Certificate to that effect stating (i) the amount of such Additional Interest that is payable and (ii) the date on which such Additional Interest is payable. Unless and until a
Responsible Officer of the Trustee 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 Officers’ Certificate setting forth the particulars of such payment. 

ARTICLE 13 

CONVERSION OF NOTES 

Section 13.01.    Conversion Privilege and Conversion Rate(a) . (a) Subject to and upon compliance with the
provisions of this Article 13, each Holder of a Note shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or a multiple thereof) of such Note (i) subject to
satisfaction of the conditions described in Section 13.01(g), at any time prior to the close of business on the Business Day immediately preceding January 15, 2028, under the circumstances and during the periods set forth in
Section 13.01(g), and (ii) regardless of the conditions described in Section 13.01(g), on or after January 15, 2028, and until the close of business on the second Business Day immediately preceding the Maturity Date, in each
case, at an initial conversion rate of 18.0317 shares of Common Stock (subject to adjustment as provided in this Article 13, the “Conversion Rate”) per $1,000 principal amount of Notes (subject to, and in accordance with, the
settlement provisions of Section 13.03, the “Conversion Obligation”). 
 (b)    If a Note is
submitted or presented for purchase pursuant to Article 16, subject to Section 13.03(b), such conversion right shall terminate at the close of business on the Business Day prior to the Fundamental Change Repurchase Date for such Note, as the
case may be (unless the Company shall fail to make the Fundamental Change Repurchase Price payment when due in accordance with Article 16, if applicable, in which case the conversion right shall terminate at the close of business on the Business Day
prior to the date such failure is cured and such Note is repurchased). 
 (c)    A Holder may convert fewer than all of
such Holder’s Notes only if (i) the principal amount of Notes converted is an integral multiple of $1,000 and (ii) the portion of such Holder’s Notes not so converted is in a minimum principal amount of $1,000. Provisions of this
Indenture that apply to conversion of all of a Note also apply to conversion of a portion of a Note. 
 (d)    A Holder
of Notes is not entitled to any rights of a Holder of Common Stock until such Holder has converted its Notes into Common Stock, and only to the extent such Notes are deemed to have been converted into Common Stock pursuant to this Article 13. 

(e)    The Conversion Rate shall be adjusted in certain instances as provided in Section 13.02 and
Section 13.07. 

  
 51 












 (f)    By delivering the number of shares of Common Stock issuable on
conversion to the Trustee, plus a cash payment for any fractional share, the Company shall be deemed to have satisfied its obligation to pay the principal amount of the Notes so converted and its obligation to pay accrued and unpaid interest
attributable to the period from the most recent Interest Payment Date through the Conversion Date (which amount will be deemed paid in full rather than canceled, extinguished or forfeited). 

(g)    (i) Prior to the close of business on the Business Day immediately preceding January 15, 2028, a Holder of
Notes may surrender all or any portion of its Notes for conversion at any time during the five (5) Business Day period immediately after any five (5) consecutive Trading Day period (the “Measurement Period”) in which the
Trading Price per $1,000 principal amount of Notes, as determined following a request by a Holder of Notes in accordance with this Section 13.01(g)(i) for each Trading Day of the Measurement Period was less than 98% of the product of the Last
Reported Sale Price of the Common Stock and the Conversion Rate on each such Trading Day. The Trading Prices shall be determined by the Bid Solicitation Agent pursuant to this Section 13.01(g)(i) and the definition of Trading Price set forth in
this Indenture. The Company shall provide written notice to the Bid Solicitation Agent (if other than the Company) of the three independent nationally recognized securities dealers selected by the Company pursuant to the definition of Trading Price,
along with appropriate contact information for each. The Bid Solicitation Agent (if other than the Company) shall have no obligation to determine the Trading Price per $1,000 principal amount of Notes unless the Company has requested such
determination, and the Company shall have no obligation to make such request (or if the Company is acting as Bid Solicitation Agent, the Company shall have no obligation to determine the Trading Price per $1,000 of Notes) unless a Holder of Notes of
at least $5,000,000 in aggregate principal amount provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes would be less than 98% of the product of the Last Reported Sale Price of the Common Stock and
the Conversion Rate, at which time the Company shall instruct the Bid Solicitation Agent (if other than the Company) to determine, or if the Company is acting as the Bid Solicitation Agent, the Company shall determine, the Trading Price per $1,000
principal amount of Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common
Stock and the Conversion Rate. If (x) the Company is not acting as Bid Solicitation Agent, and the Company does not instruct the Bid Solicitation Agent in writing to determine the Trading Price per $1,000 principal amount of Notes when
obligated as provided in the preceding sentence, or if the Company so instructs the Bid Solicitation Agent to obtain bids and the Bid Solicitation Agent fails to make such determination, or (y) the Company is acting as Bid Solicitation Agent
and the Company fails to make such determination when obligated as provided in the preceding sentence, then, in either case, the Trading Price per $1,000 principal amount of Notes shall be deemed to be less than 98% of the product of the Last
Reported Sale Price of the Common Stock and the Conversion Rate on each Trading Day of such failure. If the condition set forth in this Section 13.01(g)(i) has been met, the Company shall so notify the Holders of Notes, the Trustee and the
Conversion Agent (if other than the Trustee) in writing. If, at any time after the condition set forth in this Section 13.01(g)(i) has been met, the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the
product of the Last Reported Sale Price of the Common Stock and the Conversion Rate for such date, the Company shall so notify the Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee). 

  
 52 












 (ii)    If, prior to the close of business on the Business Day
immediately preceding January 15, 2028, the Company elects to: 
 (A)    issue to all or
substantially all Holders of the Common Stock any rights, options or warrants (other than in connection with a shareholder rights plan) entitling them, for a period of not more than forty-five (45) calendar days after the announcement date of
such issuance, to subscribe for or purchase shares of Common Stock at a price per share that is less than the average of the Last Reported Sale Prices of the Common Stock for the ten (10) consecutive Trading Day period ending on, and including,
the Trading Day immediately preceding the date of announcement of such issuance; or 
 (B)    distribute
to all or substantially all Holders of the Common Stock the Company’s assets, debt securities or rights to purchase securities of the Company, which distribution has a per share value, as reasonably determined by the Board of Directors,
exceeding 10% of the Last Reported Sale Price of the Common Stock on the Trading Day preceding the date of announcement for such distribution, 
 then, in
either case, the Company shall notify all Holders of the Notes with a copy to the Trustee and the Conversion Agent (if other than the Trustee) at least thirty-five (35) Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or
distribution. Once the Company has given such notice, a Holder of Notes may surrender all or any portion of its Notes for conversion at any time until the earlier of (1) the close of business on the Business Day immediately preceding the
Ex-Dividend Date for such issuance or distribution and (2) the Company’s announcement that such issuance or distribution will not take place, in each case, even if the Notes are not otherwise convertible at such time. 

(iii)    If (i) a transaction or event that constitutes (x) a Fundamental Change or (y) a Make-Whole
Fundamental Change occurs prior to the close of business on the Business Day immediately preceding January 15, 2028, regardless of whether a Holder of Notes has the right to require the Company to repurchase the Notes pursuant to
Section 16.01, or (ii) the Company is a party to a consolidation, merger, binding share exchange, or transfer or lease of all or substantially all of its assets prior to the close of business on the Business Day immediately preceding
January 15, 2028, in each case pursuant to which the Common Stock would be converted into cash, securities or other assets (other than a transaction that is intended primarily to change our jurisdiction of incorporation), 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 or event until thirty-five (35) Trading Days after the actual effective date of such transaction or
event, or if such transaction also constitutes a Fundamental Change, until the close of business on the day prior to the related Fundamental Change Repurchase Date. The Company shall notify Holders of Notes, the Trustee and the Conversion Agent (if
other than the Trustee) as promptly as practicable, but in no event later than the second Business Day after the date the Company publicly announces such transaction or event; provided that the Company shall deliver such notice in no event
later than the actual effective date of such transaction or event. 

  
 53 












 (iv)    Prior to the close of business on the Business Day immediately
preceding January 15, 2028, a Holder of Notes may surrender all or any portion of its Notes for conversion at any time during any fiscal quarter commencing after the fiscal quarter ending on August 31, 2021 (and only during such fiscal
quarter), if the Last Reported Sale Price of the Common Stock for at least twenty (20) Trading Days (whether or not consecutive) during the period of thirty (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 Conversion Price on each applicable Trading Day as determined by the Company. The Company, shall determine at the beginning of each fiscal quarter commencing after August 31,
2021, whether the Notes may be surrendered for conversion in accordance with this clause (iv) and shall notify the Trustee in writing if the Notes become convertible in accordance with this Section 13.01(g)(iv) and the Company shall notify
the Holders of the Notes. 
 (v)    A Note in respect of which a Holder has exercised the repurchase right upon a
Fundamental Change pursuant to Section 16.01 may be converted only if such Holder withdraws its election in accordance with Section 16.01, as applicable. 

(vi)    If the Company calls any Note for Redemption, then the Holder of such Note may convert such Note at any time
before the close of business on the second Business Day immediately before the related Redemption Date (or, if the Company fails to pay the Redemption Price due on such Redemption Date in full, at any time until such time as the Company pays such
Redemption price in full). 
 Section 13.02.    Make-Whole Fundamental Change Premium. (a) If the
Make-Whole Fundamental Change Effective Date for any Make-Whole Fundamental Change shall have occurred, then the Company shall calculate and pay a “Make-Whole Fundamental Change Premium” to the Holders of the Notes who
convert their Notes in connection with such Make-Whole Fundamental Change by adding such Make-Whole Fundamental Change Premium to the Conversion Rate for such Notes. A conversion of Notes shall be deemed for these purposes to be “in connection
with” such Make-Whole Fundamental Change if the relevant Notice of Conversion delivered pursuant to Section 13.03(a) is received by the Conversion Agent on, or subsequent to, the relevant Make-Whole Fundamental Change Effective Date but
before the related Fundamental Change Purchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for proviso (1) in clause (ii) of the definition of “Change of Control,” the 35th Trading Day immediately following such Make-Whole Fundamental Change Effective Date). The Fundamental Make-Whole Change Premium shall be in addition to, and not in substitution for, any cash,
securities or other assets otherwise due to Holders of Notes upon conversion. The number of additional shares of Common Stock per $1,000 principal amount of Notes constituting the Make-Whole Fundamental Change Premium (the “Additional
Shares”) shall be determined by reference to the table set forth in Section 13.02(b), based on the Make-Whole Fundamental Change Effective Date and the Stock Price. If the Holders of Common Stock receive only cash in the Make-Whole
Fundamental Change, the Stock Price shall be the cash amount paid per share of Common Stock in connection with such Make-Whole Fundamental Change. Otherwise, the Stock Price shall be equal to the 

  
 54 












 
average Last Reported Sale Price of the Common Stock over the ten Trading Day period ending on the Trading Day immediately preceding, and excluding, the applicable Make-Whole Fundamental Change
Effective Date. 
 (b)    The following table sets forth the number of Additional Shares to be received per $1,000
principal amount of Notes pursuant to this Section 13.02(b) for each Stock Price and Make-Whole Fundamental Change Effective Date set forth below:

 The exact Stock Prices and Make-Whole Fundamental Change Effective Dates may not be set forth in the table
above, in which case: 
 (i)    if the Stock Price is between two Stock Prices in the table above or the
Make-Whole Fundamental Change Effective Date is between two Make-Whole Fundamental Change Effective Dates in the table above, the Make-Whole Fundamental Change Premiums shall be determined by a straight-line interpolation between the Make-Whole
Fundamental Change Premiums set forth for the higher and lower Stock Prices and the earlier and later Make-Whole Fundamental Change Effective Dates, as applicable, based on a 365-day year; 

(ii)    if the Stock Price is greater than $175.00 per share (subject to adjustment in the same manner as
the Stock Prices set forth in the column headings of the table above pursuant to subsection (c) below), no Make-Whole Fundamental Change Premium shall be added to the Conversion Rate; and 

(iii)    if the Stock Price is less than $42.66 per share (subject to adjustment in the same manner as the
Stock Prices set forth in the column headings of the table above pursuant to subsection (c) below), no Make-Whole Fundamental Change Premium shall be added to the Conversion Rate. 

(c)    The Stock Prices set forth in the first row of the table above in Section 13.02(b) shall be adjusted, as of
any date on which the Conversion Rate of the Notes is adjusted other than an adjustment to the Conversion Rate by adding the Make-Whole Fundamental Change Premium. 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 the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The
Make-Whole Fundamental Change Premiums set forth in the table above shall be adjusted in the same manner as the Conversion Rate as set forth in Section 13.07 hereof, other than as a result of an adjustment to the Conversion Rate by adding the
Make-Whole Fundamental Change Premium. 

  
 55 












 (d)    The Company, or, at the written request of the Company, the
Trustee, shall mail or send electronically written notice of the anticipated Make-Whole Fundamental Change Effective Date of any Make-Whole Fundamental Change to the Holders (with a copy to the Trustee if applicable) as promptly as practicable
following the date the Company publicly announces such Make-Whole Fundamental Change, but in no event less than 20 days prior to the anticipated Make-Whole Fundamental Change Effective Date (the “Make-Whole Fundamental Change
Notice”). 
 (e)    Notwithstanding the foregoing, in no event shall the Conversion Rate exceed 23.4411 per
$1,000 principal amount as a result of this Section 13.02, subject to proportional adjustment in the same manner as the Conversion Rate as set forth in Section 13.07 hereof. 

(f)    The Make-Whole Fundamental Change Premium shall be delivered upon the settlement date for the conversion. 

Section 13.03.    Settlement upon Conversion. 

(a)    Subject to this Section 13.03, Section 13.02(a) and Section 13.11(a), upon conversion of any Notes,
the Company shall pay or deliver, as applicable, to the converting Holder, in respect of each $1,000 principal amount of Notes being converted, cash (“Cash Settlement”) or a combination of cash and shares of Common Stock, together
with cash, if applicable, in lieu of delivering any fractional share of Common Stock in accordance with Section 13.03(b)(ii) (“Combination Settlement”), at its election, as set forth in this Section 13.03. The Company will
have the right to elect the Settlement Method applicable to any conversion of a Note; provided, however, that: 

(i)    All conversions of Notes with a Conversion Date that occurs on or after January 15, 2028 will be
settled using the same Settlement Method, and the Company will send notice of such Settlement Method to Holders and the Conversion Agent no later than the open of business on January 15, 2028. 

(ii)    If the Company elects a Settlement Method with respect to the conversion of any Note whose
Conversion Date occurs before January 15, 2028, then the Company will send notice of such Settlement Method to the Holder of such Note and the Conversion Agent no later than the close of business on the Business Day immediately after such
Conversion Date. 
 (iii)    If any Notes are called for Redemption, then (1) the Company will
specify, in the related Redemption Notice sent pursuant to Section 15.01(e), the Settlement Method that will apply to all conversions of Notes with a Conversion Date that occurs on or after the related Redemption Notice Date and before the
second (2nd) Business Day before the related Redemption Date; and (2) if such Redemption Date occurs on or after January 15, 2028, then such Settlement Method must be the same Settlement
Method that, pursuant to Section 13.03(a)(i), applies to all conversions of Notes with a Conversion Date that occurs on or after January 15, 2028. 

  
 56 












 (iv)    Except for any conversions described in
Section 13.03(a)(i), 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. 
 (v)    If the Company does not timely elect a Settlement Method
with respect to the conversion of a Note, then the Company will be deemed to have elected the Default Settlement Method (and, for the avoidance of doubt, the failure to timely make such election will not constitute a Default or Event of Default).

 (vi)    If the Company timely elects Combination Settlement with respect to the conversion of a Note
but does not timely notify the Holder of such Note of the applicable Specified Dollar Amount, then the Specified Dollar Amount for such conversion will be deemed to be $1,000 per $1,000 principal amount of Notes. For the avoidance of doubt, the
Company’s failure to timely elect a Settlement Method or specify the applicable Specified Dollar Amount shall not constitute a Default or Event of Default. 

The Company may, from time to time, change the Default Settlement Method by sending notice of the new Default Settlement Method to the Holder
(with a copy to the Trustee and the Conversion Agent (if other than the Trustee)). In addition, the Company will have the right, exercisable at its election by sending notice of such exercise to the Holders (with a copy to the Trustee and the
Conversion Agent (if other than the Trustee)), to elect to irrevocably fix the Settlement Method or to irrevocably elect Combination Settlement and eliminate a Specified Dollar Amount or range of Specified Dollar Amounts. If the Company makes such
an irrevocable election, then such election will apply to all conversions of Notes with a Conversion Date that occurs on or after the date such notice is sent to Holders. In addition, if the Company irrevocably elects Combination Settlement and
eliminates a Specified Dollar Amount or range of Specified Dollar Amounts, then the Company will, if needed, simultaneously change the Default Settlement Method to Combination Settlement with a Specified Dollar Amount that is consistent with such
irrevocable election. However, in all cases, no such irrevocable election will affect any Settlement Method theretofore elected (or deemed to be elected) with respect to any Note pursuant to this Indenture and in no event may the Company elect
Combination Settlement with a Specified Dollar Amount that is less than $1,000 per $1,000 principal amount of Notes. For the avoidance of doubt, such an irrevocable election, if made, will be effective without the need to amend this Indenture or the
Notes, including pursuant to Section 9.01(k) (it being understood, however, that the Company may nonetheless choose to execute such an amendment at its option). 

If the Company changes the Default Settlement Method or irrevocably fixes the Settlement Method pursuant to this Section 13.03(a), then
the Company will either post the Default Settlement Method or fixed Settlement Method, as applicable, on the Company’s website or disclose the same in a current report on Form 8-K (or any successor form)
that is filed with, or furnished to, the SEC. 

  
 57 












 (b)    Conversion Consideration. 

(i)    Generally. Subject
to Section 13.03(b)(ii) and Section 13.03(b)(iii), the type and amount of consideration (the “Conversion Consideration”) due in respect of each $1,000 principal amount of a Note to be converted will be as
follows: 
 (1)    if Cash Settlement applies to such conversion, cash in an amount equal to the sum of the Daily
Conversion Values for each VWAP Trading Day in the Observation Period for such conversion; or 
 (2)    if Combination
Settlement applies to such conversion, consideration consisting of (A) a number of shares of Common Stock equal to the sum of the Daily Share Amounts for each VWAP Trading Day in the Observation Period for such conversion; and (B) an
amount of cash equal to the sum of the Daily Cash Amounts for each VWAP Trading Day in such Observation Period. 

(ii)    Cash in Lieu of Fractional Shares. If Combination Settlement applies to the conversion of
any Notes and the number of shares of Common Stock deliverable pursuant to Section 13.03(b)(i) upon such conversion is not a whole number, then such number will be rounded down to the nearest whole number and the Company will deliver, in
addition to the other consideration due upon such conversion, cash in lieu of the related fractional share in an amount equal to the product of (1) such fraction and (2) the Daily VWAP on the last VWAP Trading Day of the Observation Period
for such conversion. 
 (iii)    Conversion of Multiple Notes by a Single Holder. If a Holder
converts more than one (1) Note on a single Conversion Date, then the Conversion Consideration due in respect of such conversion will (in the case of any Global Note, to the extent permitted by, and practicable under, the Depositary Procedures)
be computed based on the total principal amount of Notes converted on such Conversion Date by such Holder. 

(iv)    Notice of Calculation of Conversion Consideration. The Company will determine the Conversion
Consideration due upon conversion of any Note promptly following the last VWAP Trading Day of the applicable Observation Period and will promptly thereafter, subject to the Depositary’s applicable procedures, send notice to the Trustee and the
Conversion Agent (if other than the Trustee) of the same and the calculation thereof in reasonable detail or in such detail as requested by the Depositary. Neither the Trustee nor the Conversion Agent will have any duty to make any such
determination. 
 (c)    Delivery of the Conversion Consideration. Except as set forth in Sections 13.07, the
Company will pay or deliver, as applicable, the Conversion Consideration due upon the conversion of any Note to the Holder on or before the second (2nd) Business Day immediately after the last VWAP Trading Day of the Observation Period for such
conversion. 
 (d)    A Note shall be deemed to have been converted immediately prior to the close of business on the
date (the “Conversion Date”) that the Holder has complied with the requirements set forth in Section 13.03(a). 

  
 58 












 (e)    In case any Notes shall be surrendered for partial conversion,
the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Notes so surrendered a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted
portion of the surrendered Notes, without payment of any service charge by the converting Holder but, if required by the Company or Trustee, with payment of a sum sufficient to cover any documentary, stamp or similar issue or transfer tax or similar
governmental charge required by law or that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such conversion being different from the name of the Holder of the old Notes surrendered for such
conversion. 
 (f)    Except as provided in Section 13.07, no adjustment shall be made for dividends on any shares
of Common Stock issued upon the conversion of any Notes as provided in this Article 13. 
 (g)    Subject to
Section 13.05, before any Holder of a Note shall be entitled to convert a Note as set forth above, such Holder shall (i) in the case of a Global Notes, comply with the procedures of the Depositary in effect at that time and, if required,
pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 13.03(h) and (ii) in the case of Notes in certificated form or when required by applicable procedures of the
Depository in effect at that time in the case of a Global Note, (1) complete, manually sign and deliver an irrevocable notice to the Conversion Agent as set forth in the form of Notice of Conversion (or a facsimile thereof) (a “Notice
of Conversion”) at the office of the Conversion Agent and state in writing therein the principal amount of Notes to be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates for any
shares of Common Stock to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the
office of the Conversion Agent, (3) if required, furnish appropriate endorsements and transfer documents and (4) if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set
forth in Section 13.03(i). The Trustee (and, if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article 13 on the Conversion Date for such conversion. No Notice of Conversion with respect to any
Notes may be surrendered by a Holder thereof if such Holder has also delivered a Fundamental Change Repurchase Notice to the Company in respect of such Notes and has not validly withdrawn such Fundamental Change Repurchase Notice in accordance with
Section 16.01. 
 (h)    Holders of the Notes at the close of business on a Regular Record Date will receive
payment of interest payable on the corresponding Interest Payment Date notwithstanding the conversion of such Notes at any time after the close of business on the applicable Regular Record Date. Notes surrendered for conversion by a Holder during
the period from the close of business on any Regular Record Date to the opening of business on the next Interest Payment Date must be accompanied by payment of an amount equal to the interest that the Holder is to receive on the Notes;
provided, however, that no such payment need be made (1) if the Company has specified a Fundamental Change Purchase Date that is after a record date and on or prior to the business day immediately following the corresponding
Interest Payment Date, (2) to the extent of overdue interest, if any overdue interest exists at the time of conversion with respect to such Note, or (3) if conversion occurs after the last record date prior to the stated Maturity Date.


  
 59 












 (i)    Upon the conversion of an interest in a Global Note, the Trustee,
or the Custodian at the direction of the Trustee, shall make a notation on such Global Notes as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversion of Notes effected through
any Conversion Agent other than the Trustee. 
 (j)    Upon conversion, a Holder shall not receive any separate cash
payment for accrued and unpaid Interest, if any, except as set forth below. The Company’s settlement of the full Conversion Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the Notes and accrued and
unpaid Interest, if any, to, but excluding, the relevant Conversion Date. As a result, accrued and unpaid Interest, if any, to, but excluding, the relevant Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or
forfeited. Upon a conversion of Notes into a combination of cash and shares of Common Stock, accrued and unpaid Interest, if any, will be deemed to be paid first out of the cash paid upon such conversion. Notwithstanding the foregoing, if Notes are
converted after the close of business on a record date, Holders of such Notes as of the close of business on such record date will receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding
the conversion. Notes surrendered for conversion during the period from the close of business on any record date to the open of business on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of interest
payable on the Notes so converted; provided that no such payment shall be required (1) if the Company has specified a Fundamental Change Repurchase Date that is after a record date and on or prior to the Scheduled Trading Day immediately
succeeding the corresponding Interest Payment Date; (2) to the extent any Defaulted Interest, if any, exists at the time of conversion with respect to such Notes; or (3) for conversions following the record date immediately preceding the
Maturity Date. Therefore, for the avoidance of doubt, all Holders of record on the record date immediately preceding the Maturity Date and any Fundamental Change Repurchase Date as described in the immediately preceding sentence shall receive the
full interest payment due on the Maturity Date or other applicable Interest Payment Date regardless of whether their Notes have been converted following such record date. 

(k)    The Person in whose name the certificate for any shares of Common Stock delivered upon conversion is registered
shall be treated as a shareholder of record as of the close of business on the last Trading Day of the relevant Observation Period. Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered for conversion. 

Section 13.04.    Reserved. 

Section 13.05.    Taxes on Conversion. Except as provided in the next sentence, the Company shall pay any and
all documentary, stamp or similar issue or transfer tax due and duties on the issuance of shares of Common Stock upon conversion of Notes pursuant hereto. A Holder delivering a Note for conversion shall be liable for and shall be required to pay any
tax or duty which may be payable in respect of any transfer involved in the issue and delivery of shares of Common Stock in a name other than that of the Holder of the Note or Notes to be converted, and no such issue or delivery shall be made unless
the Person requesting such issue has paid to the Company the amount of any such tax or duty, or has established to the satisfaction of the Company that such tax or duty has been paid. 

  
 60 












 Section 13.06.    Company to Provide Common Stock.
(a) The Company shall, prior to issuance of any Notes hereunder, and from time to time as may be necessary, reserve, out of its authorized but unissued Common Stock, a sufficient number of shares of Common Stock to permit the conversion of all
Outstanding Notes into shares of Common Stock. 
 (b)    All shares of Common Stock delivered upon conversion of the
Notes shall be newly issued shares, shall be duly authorized, validly issued, fully paid and nonassessable and shall be free from preemptive or similar rights and free of any lien or adverse claim as the result of any action by the Company. 

Section 13.07.    Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by
the Company if any of the following events occurs, except that the Company shall not make any adjustments to the Conversion Rate if Holders of the Notes participate (other than in the case of a share split or share combination), at the same time and
upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions described in this Section 13.07, without having to convert their Notes, as if they held a number of shares of Common
Stock equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder. 

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

			
	CR1 = CR0 ×	 	  OS1  
	 	  OS0

 where, 
  

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

 Any adjustments made pursuant to this Section 13.07(a) shall become effective immediately after
(x) the open of business on the Ex-Dividend Date for such dividend or distribution or (y) the open of business on the effective date of such split or combination, as applicable. If any dividend or
distribution described in this Section 13.07(a) is declared but not so paid or made, effective as of the date the Board of Directors determines not to pay such dividend or distribution, the new Conversion Rate shall again be adjusted to the
Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 

  
 61 












 (b)    If the Company distributes to all or substantially all holders of
Common Stock any rights, options or warrants entitling them to purchase, for a period of not more than 45 days after the Ex-Dividend Date for the distribution, shares of Common Stock at a price per share less
than the average of the Last Reported Sale Prices of the Common Stock for the ten consecutive Trading Day period ending on the Trading Day immediately preceding the announcement date for such distribution, the Conversion Rate shall be adjusted based
on the following formula: 
  

			
	CR1 = CR0 ×	 	  OS0 + X   
	 	  OS0 + Y

 where, 
  

					
	CR0	 	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;
			
	CR1	 	=	  	the new Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such distribution;
			
	OS0	 	=	  	the number of shares of Common Stock outstanding immediately prior to the open of business on the Ex-Dividend Date for such distribution;
			
	X	 	=	  	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
			
	Y	 	=	  	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants divided by the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day
period ending on, and including, the Trading Day immediately preceding the declaration date for such distribution.

 For purposes of this Section 13.07(b), in determining whether any rights, options or warrants entitle the
Holders to subscribe for or purchase shares of Common Stock at less than the average of the Last Reported Sale Prices of the Common Stock for the applicable ten consecutive Trading Day period, 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, with the value of such consideration if other than cash, to be determined by the Board of Directors. 

Any adjustment made pursuant to this Section 13.07(b) shall be made successively whenever any such rights, options or warrants are
distributed and shall become effective immediately after the open of business on the Ex-Dividend Date for such distribution. To the extent that shares of Common Stock are not delivered after the expiration of
such rights, options or warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only
the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so distributed, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if the
Ex-Dividend Date for such distribution had not occurred. 
 (c)    If the
Company distributes shares of its Capital Stock, evidences of its indebtedness or other assets or property of the Company or rights, options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of the
Common Stock, excluding: 
 (i)    dividends, distributions (including share splits), rights, options or
warrants as to which an adjustment is effected in Section 13.07(a), Section 13.07(b) or Section 13.07(e); 

  
 62 












 (ii)    dividends or distributions covered by
Section 13.07(d); 
 (iii)    dividends or distributions that constitute Reference Property
following an event described in Section 13.11; and 
 (iv)    Spin-Offs to which the provisions set
forth below in this Section 13.07(c) shall apply, 
 then the applicable Conversion Rate shall be adjusted based on the following formula: 

 

			
	CR1 = CR0 ×	 	        SP0        
	 	  SP0 - FMV

 where, 
  

					
	CR0	 	=	  	the applicable Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;
			
	CR1	 	=	  	the applicable Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such distribution;
			
	SP0	 	=	  	the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend
Date for such distribution; and
			
	FMV	 	=	  	the fair market value (as determined in good faith by the Board of Directors) of the shares of Capital Stock, evidences of indebtedness, assets, property, rights, options or warrants distributed with respect to each outstanding
share of Common Stock as of the open of business on the Ex-Dividend Date for such distribution.

 Any adjustment made under the portion of this Section 13.07(c) above shall become effective immediately
after the open of business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect
if such dividend or distribution had not been declared. 
 If “FMV” as set forth above is equal to or greater than “SP0” as set forth above, in lieu of the foregoing adjustment, Holders of the Notes shall receive, in respect of each $1,000 principal amount of Notes, at the same time and upon the same terms as
holders of Common Stock, the amount and kind of the Company’s Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights, options or warrants to acquire the Company’s Capital Stock or other securities
that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the applicable Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date
for the distribution. 
 With respect to an adjustment pursuant to this Section 13.07(c) where there has been a payment of a dividend
or other distribution on the Common Stock of shares of the Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit that are, or, when issued, will be, traded or quoted on any national
or regional securities 

  
 63 












 
exchange or other market (a “Spin-Off”), the applicable Conversion Rate shall instead be adjusted based on the following formula: 

 

			
	CR1 = CR0 ×	 	  FMV0 + MP0  
	 	        MP0

 where, 
  

					
	CR0	 	=	  	the applicable Conversion Rate in effect immediately prior to the end of the Valuation Period;
			
	CR1	 	=	  	the applicable 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 of the Company or similar equity interest distributed to Holders of Common Stock applicable to one share of Common Stock (determined by reference to the definition of
Last Reported Sale Price as set forth in Section 1.01 as if references therein to Common Stock were to such Capital Stock or similar equity interest) over the first ten consecutive Trading Day period immediately following the Ex-Dividend Date for such Spin-Off (such period, the “Valuation Period”); and
			
	MP0	 	=	  	the average of the Last Reported Sale Prices of Common Stock over the Valuation Period.

 Such adjustment shall occur immediately after the tenth Trading Day immediately following the Ex-Dividend Date of such Spin-Off; provided that, for purposes of determining the Conversion Rate in respect of any conversion during the ten Trading Days following the
Ex-Dividend Date of any Spin-Off, references within the previous paragraph related to “Spin-Offs” to ten Trading Days shall be deemed replaced with such lesser
number of Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off and the relevant Conversion Date. If any such dividend or distribution described in
the preceding paragraph of this Section 13.07(c) is declared but not paid or made, the new Conversion Rate shall be readjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 

For purposes of this Section 13.07(c) (and subject in all respect to Section 13.15), rights, options or warrants distributed by the
Company to all Holders of its Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the
occurrence of a specified event or events (“Trigger Event”), (i) are deemed to be transferred with such shares of the Common Stock, (ii) are not exercisable, and (iii) are also issued in respect of future issuances of the
Common Stock, shall be deemed not to have been distributed for purposes of this Section 13.07(c) (and no adjustment to the Conversion Rate under this Section 13.07(c) shall be required) until the occurrence of the earliest Trigger Event,
whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 13.07(c). If any such right, option or warrant,
including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities,
evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date with respect to new rights, options or
warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the Holders thereof). In addition, in the event of any distribution (or deemed
distribution) of rights, options or warrants, or any Trigger Event or other event of the type described in the immediately preceding sentence with respect thereto that was counted for purposes of calculating a distribution amount for which


  
 64 












 
an adjustment to the Conversion Rate under this Section 13.07(c) was made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or purchased without
exercise by any Holders thereof, upon such final redemption or purchase (x) the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion Rate shall then again be readjusted to
give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by a Holder or Holders of Common Stock with respect to
such rights, options or warrants (assuming such Holder had retained such rights, options or warrants), made to all Holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights, options or warrants
that shall have expired or been terminated without exercise by any Holders thereof, the Conversion Rate shall be readjusted as if such rights, options and warrants had not been issued. 

For purposes of Section 13.07(a), Section 13.07(b) and this Section 13.07(c), any dividend or distribution to which this
Section 13.07(c) is applicable that also includes one or both of: 
 (A)    a dividend or distribution of shares of
Common Stock to which Section 13.07(a) is applicable (the “Clause A Distribution”); or 
 (B)    a
dividend or distribution of rights, options or warrants to which Section 13.07(b) is applicable (the “Clause B Distribution”), 
 then
(1) such dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 13.07(c) is applicable (the “Clause C
Distribution”) and any Conversion Rate adjustment required by this Section 13.07(c) with respect to such Clause C Distribution shall then be made, and (2) the Clause A Distribution and Clause B Distribution shall be deemed to
immediately follow the Clause C Distribution and any Conversion Rate adjustment required by Section 13.07(a) and Section 13.07(b) with respect thereto shall then be made, except that, if determined by the Company (I) the “Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and
(II) any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to such dividend, distribution, share split or share combination, as the case may
be” within the meaning of Section 13.07(a) or “outstanding immediately prior to the open of business on the Ex-Dividend Date for such distribution” within the meaning of
Section 13.07(b). 
 (d)    If any cash dividend or cash distribution is made to all or substantially all Holders
of Common Stock to the extent that the aggregate of all such cash dividends or distributions paid in any fiscal quarter exceeds the dividend threshold amount (the “DTA”) for such fiscal quarter, the Conversion Rate shall be adjusted
based on the following formula: 
  

			
	CR1 = CR0 ×	 	   SP0 -
DTA    
	 	   SP0 - C


  
 65 












 where, 
  

					
	CR0	 	=	  	the applicable Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	CR1	 	=	  	the applicable Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	SP0	 	=	  	the average of the 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 Ex-Dividend
Date for such dividend or distribution;
			
	DTA	 	=	  	the dividend threshold amount, which shall initially be $0.27 per share per fiscal quarter; and
			
	C	 	=	  	the amount in cash per share of Common Stock the Company distributes to Holders of Common Stock.

 An adjustment to the Conversion Rate made pursuant to this Section 13.07(d) shall become effective
immediately after the open of business on the Ex-Dividend Date for the applicable dividend or distribution. If any dividend or distribution described in this Section 13.07(d) is declared but not so paid
or made, the new Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 

The DTA is subject to adjustment on an inversely proportional basis whenever the conversion rate is adjusted other than adjustments made
pursuant to this Section 13.07(d). If an adjustment is required to be made as set forth in this Section 13.07(d) as a result of a distribution that is not a regular quarterly dividend, the DTA will be deemed to be zero with respect to that
particular adjustment. 
 If “C” as set forth above is equal to or greater than “SP0” as set forth above, in lieu of the foregoing adjustment, each Holder of a Note shall receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as holders
of shares of Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the applicable Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such cash dividend or distribution. 
 (e)    If the Company or
any of its Subsidiaries makes a payment in respect of a tender or exchange offer for Common Stock, if (a) the cash and value of any other consideration included in the payment per share of Common Stock exceeds (b) the average of the Last
Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer (the
“Expiration Date”), the Conversion Rate shall be adjusted based on the following formula: 
  

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

 where, 
  

					
	CR0	 	=	  	the applicable Conversion Rate in effect immediately prior to the open of business on the Trading Day next succeeding the Expiration Date;
			
	CR1	 	=	  	the applicable Conversion Rate in effect immediately after the open of business on the Trading Day next succeeding the Expiration Date;
			
	AC	 	=	  	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares purchased in such tender offer or exchange offer;


  
 66 













					
	OS0	 	=	  	the number of shares of Common Stock outstanding immediately prior to time (the “Expiration Time”) such tender or exchange offer expires (prior to giving effect to such tender offer or exchange offer);
			
	OS1	 	=	  	the number of shares of Common Stock outstanding immediately after the Expiration Time (after giving effect to such tender offer or exchange offer); and
			
	SP1	 	=	  	the average of the Last Reported Sale Prices of the Common Stock over the ten (10) consecutive Trading Day period commencing on, and including the Trading Day next succeeding the Expiration Date.

 The adjustment to the Conversion Rate under this Section 13.07(e) shall become effective immediately
following the close of business on the Trading Day next succeeding the Expiration Date. If the Company or one of its Subsidiaries is obligated to purchase Common Stock pursuant to any such tender or exchange offer but is permanently prevented by
applicable law from effecting any such purchase or all such purchases are rescinded, the new Conversion Rate shall be readjusted to be the Conversion Rate that would be in effect if such tender or exchange offer had not been made. 

(f)    Notwithstanding the foregoing, if an adjustment pursuant to this Section 13.07 becomes effective on any Ex-Dividend Date as described above, and a Holder that has surrendered its notes for conversion 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 pursuant to Section 13.03 based on an adjusted Conversion Rate for such Ex-Dividend Date, then,
notwithstanding this Section 13.07, the Conversion Rate adjustment described in this Section 13.07 relating to such Ex-Dividend Date will not be made for such Holder. Instead, such Holder will be
treated as if such Holder were the record owner of the shares of the Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment. 

Section 13.08.    When No Adjustment is Required. (a) No adjustment in the Conversion Rate shall
be required unless such adjustment would require an increase or decrease of at least 1% in the Conversion Rate as last adjusted; provided, however, that any adjustments which would be required to be made but for this
Section 13.08(a) shall be carried forward and taken into account in any subsequent adjustment and any carry forward amount shall be paid to the Holder upon conversion regardless of the 1% threshold. All calculations under this Article 13 shall
be made to the nearest cent or to the nearest 1/10,000th of a share. 
 (b)    If the application of the foregoing
formulas in Section 13.07 would result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate shall be made (except on account of share combinations). 

(c)    No adjustment to the Conversion Rate shall be made unless as specifically set forth in Section 13.07 and
Section 13.02. Without limiting the foregoing, no adjustment to the Conversion Rate need be made: 

(i)    upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for
the reinvestment of dividends or interest payable on securities of the Company and the investment of additional optional amounts in shares of Common Stock under any plan; 

  
 67 












 (ii)    upon the issuance of any shares of Common Stock
or options or rights to purchase shares of Common Stock pursuant to any present or future employee, director or consultant benefit plan or program or employee stock purchase plan of, or assumed by, the Company or any of its Subsidiaries; 

(iii)    upon the issuance of any shares of Common Stock pursuant to any option, warrant, right, or
exercisable, exchangeable or convertible security not described in clause (ii) above and outstanding as of the Issue Date; 

(iv)    upon the issuance of Rights under the Rights Plan unless, prior to conversion, the Rights issued
under the Rights Plan have separated from the Common Stock; 
 (v)    for a change in the par value of
the Common Stock; or 
 (vi)    for accrued and unpaid interest (including any Special Interest and
Additional Interest, if applicable). 
 The Company will not take any voluntary action that would result in an adjustment to the conversion
rate pursuant to Section 13.07 without complying, if applicable, with the shareholder approval rules of the New York Stock Exchange and any similar rule of any stock exchange on which our Common Stock is listed at the relevant time. In
accordance with such listing standards, this restriction will apply at any time when the notes are outstanding, regardless of whether the Company then has a class of securities listed on the New York Stock Exchange. 

Section 13.09.    Notice of Adjustment. Whenever the Conversion Rate or conversion privilege is required to be
adjusted pursuant to this Indenture, the Company shall promptly mail to Holders a notice of the adjustment and file with the Trustee (and the Conversion Agent if other than the Trustee) an Officers’ Certificate briefly stating the facts
requiring the adjustment, the adjusted Conversion Rate and the manner of computing it. Failure to mail such notice or any defect therein shall not affect the validity of any such adjustment. Unless and until the Trustee shall receive an
Officers’ Certificate setting forth an adjustment of the Conversion Rate, the Trustee may assume without inquiry that the Conversion Rate has not been adjusted and that the last Conversion Rate of which it has knowledge remains in effect. 

Section 13.10.    Notice of Certain Transactions. In the event that there is a dissolution or liquidation of
the Company, the Company shall mail to Holders and file with the Trustee a written notice stating the proposed effective date. The Company shall mail such notice at least 20 days before such proposed effective date. Failure to mail such notice or
any defect therein shall not affect the validity of any transaction referred to in this Section 13.10. 

Section 13.11.    Effect of Reclassification, Consolidation, Merger or Sale On Conversion
Privilege. 
 (a)    If any of the following events occur: 

(i)    any recapitalization, reclassification or change of the outstanding shares of Common Stock (other
than changes resulting from a subdivision or combination); 

  
 68 












 (ii)    any consolidation, merger, or combination
involving the Company; 
 (iii)    any sale, conveyance or lease to any third party of all or
substantially all of the property and assets of the Company and its Subsidiaries; or 
 (iv)    any
statutory share exchange, 
 in each case, as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other
property or assets (including cash or any combination thereof) (any such event, a “Merger Event”), then, at and after the effective time of such Merger Event, the right to convert each $1,000 principal amount of Notes shall be
changed into a right to convert such principal amount of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a Holder of a number of shares of Common Stock
equal to the Conversion Rate immediately prior to such Merger Event would have owned or been entitled to receive (the “Reference Property”, with each “unit of Reference Property” meaning the kind and amount of
Reference Property that a Holder of one share of Common Stock is entitled to receive) upon such Merger Event and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may be, shall
execute with the Trustee a supplemental indenture permitted under Section 9.01(c) providing for such change in the right to convert each $1,000 principal amount of Notes; provided, however, that at and after the effective time of
the Merger Event (A) the Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of Notes in accordance with Section 13.03 and (B) (I) any amount
payable in cash upon conversion of the Notes in accordance with Section 13.03 shall continue to be payable in cash, (II) any shares of Common Stock that the Company would have been required to deliver upon conversion of the Notes in
accordance with Section 13.03 shall instead be deliverable in the amount and type of Reference Property that a Holder of that number of shares of Common Stock would have received in such Merger Event and (III) the Daily VWAP shall be
calculated based on the value of a unit of Reference Property. 
 If the Merger Event causes the Common Stock to be converted into, or
exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of shareholder election), then (i) the Reference Property into which the Notes will be convertible shall be deemed to be
(x) the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election or (y) if no holders of Common Stock affirmatively make such an election, the types and
amounts of consideration actually received by the holders of Common Stock, and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable
to one share of Common Stock. If the holders receive only cash in such Merger Event, then for all conversions that occur after the effective date of such Merger Event (A) the consideration due upon conversion of each $1,000 principal amount of
Notes shall be solely cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased by any Additional Shares pursuant to Section 13.02), multiplied by the price paid per share of Common Stock in
such Merger Event and (B) the Company shall satisfy the Conversion Obligation by paying cash to converting Holders on the third (3rd) Business Day immediately following the relevant
Conversion Date. The Company shall notify Holders, the 

  
 69 












 
Trustee and the Conversion Agent (if other than the Trustee), in writing, of such weighted average as soon as practicable after such determination is made but in no event later than the third (3rd) Business Day following the effective date of the Merger Event. 
 Such supplemental
indenture described in the second immediately preceding paragraph shall provide for anti-dilution and other adjustments that shall be as nearly equivalent as is possible to the adjustments provided for in this Article 13. If, in the case of any
Merger Event, the Reference Property includes shares of stock, securities or other property or assets (including cash or any combination thereof) of a Person other than the successor or purchasing corporation, as the case may be, in such Merger
Event, then such supplemental indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the holders of the Notes as the Board of Directors shall reasonably consider necessary by
reason of the foregoing. 
 (b)    When the Company executes a supplemental indenture pursuant to subsection (a) of
this Section 13.11, the Company shall promptly file with the Trustee an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or asset that will comprise a unit of Reference Property
after any such Merger Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly mail notice thereof to all Holders. The Company shall cause notice of the execution of such
supplemental indenture to be mailed to each Holder, at its address appearing on the Security Register provided for in this Indenture, within twenty (20) days after execution thereof. Failure to deliver such notice shall not affect the legality
or validity of such supplemental indenture. 
 (c)    The Company shall not become a party to any Merger Event unless
its terms are consistent with this Section 13.11. None of the foregoing provisions shall affect the right of a Holder of Notes to convert its Notes into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as
applicable, as set forth in Article 13 prior to the effective date of such Merger Event. 
 (d)    The above provisions
of this Section 13.11 shall similarly apply to successive Merger Events. Upon the consummation of any Merger Event, references to “Common Stock” shall be deemed to refer to any Reference Property that constitutes Capital Stock after
giving effect to such Merger Event. 
 If this Section 13.11 applies to any event or occurrence, Section 13.07 hereof shall not
apply. 
 Section 13.12.    Trustee’s Disclaimer. (a) The Trustee shall have no duty
to determine, or liability in connection therewith, when an adjustment under this Article 13 should be made, how it should be made or what such adjustment should be, but may accept as conclusive evidence of that fact or the correctness of any such
adjustment, and shall be protected in conclusively relying upon, an Officers’ Certificate, including the Officers’ Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 13.09.
Unless and until the Trustee receives such Officers’ Certificate delivered pursuant to Section 13.09, the Trustee may assume without inquiry that no such adjustment has been made and the last Conversion Rate of which the Trustee has
knowledge remains in effect. The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of Notes, and the Trustee shall not be responsible for the Company’s failure to comply with any
provisions of this Article 13. 

  
 70 












 (b)    The Trustee shall not be under any responsibility to determine
the correctness of any provisions contained in any supplemental indenture executed pursuant to Section 13.11, but may accept as conclusive evidence of the correctness thereof, and shall be fully protected in conclusively relying upon, the
Officers’ Certificate and Opinion of Counsel, with respect thereto which the Company are obligated to file with the Trustee pursuant to Section 13.11 and Section 10.01, respectively. 

Section 13.13.    Voluntary Increase; NYSE Compliance. (a) Subject to Section 9.01(e), the Company
from time to time may increase the Conversion Rate, to the extent permitted by law and subject to any applicable shareholder approval requirements pursuant to the listing standards of The New York Stock Exchange or such other United States
securities exchange on which the Common Stock is traded, by any amount for any period of at least 20 days, if the Board of Directors determines that such increase shall be in the Company’s best interests. The Company may (but is not required
to) make such increase in the Conversion Rate (in addition to others provided in this Indenture) as the Board of Directors deems advisable to avoid or diminish any income tax to holders of Common Stock resulting from a dividend or distribution of
stock, or rights to acquire stock, or similar event; provided, however, that in no event may the Company increase the Conversion Rate such that it causes the Conversion Price to be less than the par value of a share of Common Stock.
The Company shall provide at least 15 days’ written notice to Holders and the Trustee of any increase under this Section 13.13. 

Section 13.14.    Adjustments of Prices. Whenever any provision of this Indenture requires us to calculate the
Last Reported Sale Prices, the Daily VWAP or the Daily Conversion Values over a span of multiple days (including an Observation Period and the period for determining Stock Price for purposes of a Make-Whole Fundamental Change), the Company will make
appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date, effective
date or expiration date of the event occurs, at any time during the period when the Last Reported Sale Prices, the Daily VWAP or the Daily Conversion Values are to be calculated. The Company will provide a schedule of its calculations to each of the
Trustee and the Conversion Agent (if other than the Trustee), and each of the Trustee and Conversion Agent (if other than the Trustee) are entitled to rely conclusively upon the accuracy of its calculations without independent verification. 

Section 13.15.    Rights Plan. To the extent that the Company has a Rights Plan in effect upon conversion of
the Notes into Common Stock, the Holders shall receive upon conversion of the Notes, the Rights under the Rights Plan, unless prior to conversion, the Rights have separated from the Common Stock, in which case, and only in such case, the Conversion
Rate shall be adjusted at the time of separation as if the Company distributed to all or substantially all Holders of Common Stock shares of the Company’s Capital Stock, evidences of indebtedness or other assets or property of ours or rights,
options or warrants to acquire the Company’s Capital Stock or other securities as described in Section 13.07(c) above, subject to readjustment in the event of the expiration, termination or redemption of such Rights.

 OPTIONAL REDEMPTION 

Section 15.01.    Right of the Company to Redeem the Notes. 

(a)    No Right to Redeem Before April 15, 2025. The Company may not redeem the Notes at its
option at any time before April 15, 2025. 
 (b)    Right to Redeem the Notes on or After
April 15, 2025. Subject to the terms of this Section 15.01, the Company has the right, at its election, to redeem all, or any portion in an authorized denomination, of the Notes, at any time and from time to time, on a
Redemption Date on or after April 15, 2025 and on or before the fortieth (40th) Scheduled Trading Day immediately before the Maturity Date, for a cash purchase price equal to the Redemption Price, but only if the Last Reported Sale Price per
share of Common Stock exceeds one hundred and thirty percent (130%) of the Conversion Price on (i) each of at least twenty (20) Trading Days (whether or not consecutive) during the thirty (30) consecutive Trading Days ending on, and
including, the Trading Day immediately before the Redemption Notice Date for such Redemption; and (ii) the Trading Day immediately before such Redemption Notice Date. For the avoidance of doubt, the calling of any Notes for Redemption will
constitute a Make-Whole Fundamental Change with respect to that Note, in which case the Conversion Rate applicable to the conversion of that Note will be increased in certain circumstances if it is converted after it is called for Redemption. If the
Company elects to redeem less than all of the outstanding Notes, then the Redemption will not constitute a Make-Whole Fundamental Change with respect to the Notes not called for Redemption, and Holders of the Notes not called for Redemption will not
be entitled to an increased Conversion Rate for such Notes as described above on account of the Redemption, except to the limited extent described further below. 

(c)    Redemption Date. The Redemption Date for any Redemption will be a Business Day of the Company’s
choosing that is no more than sixty-five (65), nor less than forty-five (45), Scheduled Trading Days after the Redemption Notice Date for such Redemption. 

(d)    Redemption Price. The Redemption Price for any Note called for Redemption will be an amount in cash equal to
the principal amount of such Note plus accrued and unpaid interest on such Note to, but excluding, the Redemption Date for such Redemption; provided, however, that if such Redemption Date is after a Regular Record Date and on or before
the next Interest Payment Date, then (i) the Holder of such Note at the close of business on such Regular Record Date will be entitled, notwithstanding such Redemption, to receive, on or, at the Company’s election, before such Interest
Payment Date, the unpaid interest that would have accrued on such Note to, but excluding, such Interest Payment Date; and (ii) the Redemption Price will not include accrued and unpaid interest on such Note to, but excluding, such Redemption
Date. 

  
 72 












 (e)    Redemption Notice. To call any Notes for Redemption, the
Company must (x) send to each Holder of such Notes, the Trustee and the Paying Agent (if other than the Trustee) a written notice of such Redemption (a “Redemption Notice”) and (y) substantially contemporaneously
therewith, issue a press release through such national newswire service as the Company then uses (or publish the same through such other widely disseminated public medium as the Company then uses, including its website) containing the information
set forth in the Redemption Notice. If the Trustee is so directed by written notice set forth in an Officer’s Certificate to deliver such Redemption Notice, the Company shall provide such notice to the Trustee no less than 2 Business Days
before the notice is to be delivered to Holders, unless a shorter period shall be agreed to by the Trustee. 
 Such Redemption Notice must
state: 
 (i)    that the Notes have been called for Redemption, briefly describing the Company’s
Redemption right under this Indenture; 
 (ii)    the Redemption Date for such Redemption; 

(iii)    the Redemption Price per $1,000 principal amount of Notes for such Redemption (and, if the
Redemption Date is after a Regular Record Date and on or before the next Interest Payment Date, the amount, manner and timing of the interest payment payable pursuant to the proviso to Section 15.01(d)); 

(iv)    the name and address of the Paying Agent and the Conversion Agent; 

(v)    that Notes called for Redemption may be converted at any time before the close of business on the
second Business Day immediately before the Redemption Date (or, if the Company fails to pay the Redemption Price due on such Redemption Date in full, at any time until such time as the Company pays such Redemption Price in full); 

(vi)    the Conversion Rate in effect on the Redemption Notice Date for such Redemption and a description
of any adjustments to the Conversion Rate that may result from such Redemption (including pursuant to Section 13.02(b)); 

(vii)    the Settlement Method that will apply to all conversions of Notes with a Conversion Date that
occurs on or after such Redemption Notice Date and before such Redemption Date; and 
 (viii)    the
CUSIP and ISIN numbers, if any, of the Notes. 
 On or before the Redemption Notice Date, the Company will send a copy of such Redemption
Notice to the Trustee and the Paying Agent (if other than the Trustee). 
 (f)    Selection, Conversion and Transfer
of Notes to be Redeemed in Part. If fewer than all of the outstanding Notes are to be redeemed, the Notes to be redeemed will be selected by lot according to the Depositary’s Applicable Procedures, in the case of Notes represented by a
Global Note, or, in the case of Notes represented by Physical Notes, on a pro rata or by lot basis or by another method the Trustee deems to be appropriate and fair. If less than all Notes then outstanding are called for Redemption, then the
converted portion of such Note will be deemed to be from the portion of such Note that was subject to Redemption. 

  
 73 












 (g)    If the Company elects to redeem less than all of the outstanding
Notes pursuant to this Section 15.01, 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 forty-second (42nd) Scheduled Trading Day
immediately before the Redemption Date for such Redemption, whether such Note or beneficial interest, as applicable, is to be redeemed pursuant to such Redemption, then such Holder or owner, as applicable, will be entitled 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, and each such conversion will be deemed to be of a Note called for Redemption for purposes of this
Section 15.01 and Sections 13.01(g)(vi) and 13.02(b). 
 (h)    Redemption Prohibited in Certain
Circumstances. If the principal amount of the Notes has been accelerated and such acceleration has not been rescinded on or before the Redemption Date (including as a result of the payment of the related Redemption Price, and any related
interest pursuant to the proviso to Section 15.01(d), on such Redemption Date), then the Company may not call for Redemption or otherwise redeem any Notes pursuant to this Section 15.01. 

ARTICLE 16 

REPURCHASE OF NOTES UPON A FUNDAMENTAL
CHANGE 
 Section 16.01.    Repurchase of Notes at Option of the Holder Upon
a Fundamental Change. (a) If a Fundamental Change occurs prior to the Maturity Date, each Holder of a Note shall have the right, at the option of the Holder, to require the Company to repurchase all or any of such Holder’s Notes
at the Fundamental Change Repurchase Price, on the date specified by the Company that is not less than twenty (20) days and not more than thirty-five (35) days after the date of the Fundamental Change Company Notice pursuant to
Section 16.01(b) (the “Fundamental Change Repurchase Date”). If the Fundamental Change Repurchase Date is after a Regular Record Date and on or prior to the corresponding Interest Payment Date, the Company shall pay accrued and
unpaid interest to the Holder of a Note of record at the close of business on such Regular Record Date and the Fundamental Change Repurchase Price shall be 100% of the principal amount of the Notes to be repurchased. A Holder may require the Company
to repurchase fewer than all of such Holder’s Notes only if (i) the principal amount of Notes to be repurchased is an integral multiple of $1,000 and (ii) the portion of such Holder’s Notes not to be repurchased is in a minimum
principal amount of $1,000. 
 (b)    On or before the 15th day after the Fundamental Change Effective Date, the
Company, or, at the written request of the Company, the Trustee, shall mail a written notice by first-class mail or electronically of the occurrence of the Fundamental Change, and of the repurchase right arising therefrom, to the Trustee, Paying
Agent (if other than the Trustee) and to each Holder at the address shown in the Note Register of the Note Registrar (and to beneficial owners as required by applicable law) (the “Fundamental Change Company Notice”). Simultaneously
with providing such Fundamental Change Company Notice, the Company shall 

  
 74 












 
publish a notice containing the information that is required in the Fundamental Change Company Notice in a newspaper of general circulation in The City of New York or publish information on a
website of the Company or through such other public medium the Company may use at that time. The Fundamental Change Company Notice shall set forth the Holder’s right to require the Company to purchase the Notes and specify: 

(i)    the events causing such Fundamental Change; 

(ii)    the date of such Fundamental Change; 

(iii)    the last date by which the Fundamental Repurchase Notice must be delivered to elect the repurchase
option pursuant to this Section 16.01; 
 (iv)    the Fundamental Change Repurchase Price; 

(v)    the Fundamental Change Repurchase Date; 

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

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

(viii)    the procedures that the Holder must follow to require the Company to repurchase its Notes under
this Section 16.01. 
 At the Company’s written request, the Trustee shall give such Fundamental Change Company Notice in the
Company’s name and at the Company’s expense; provided that, unless otherwise agreed by the Trustee, the Company makes such request at least five Business Days prior to the date by which such Fundamental Change Company Notice must be
given to the Holders in accordance with this Section 16.01; provided, further, that the text of such Fundamental Change Company Notice shall be prepared by the Company. If any of the Notes is in the form of a Global Note, then the
Company shall modify such notice to the extent necessary to accord with the Applicable Procedures relating to the purchase of Global Notes. 

No failure of the Company to give the foregoing notices or defect therein shall limit any Holder’s right to exercise its right to cause
the Company to repurchase such Holder’s Notes pursuant to this Section 16.01. 
 (c)    Repurchases of Notes
under this Article 16 shall be made upon delivery to the Paying Agent by the Holder of a duly completed notice (the “Fundamental Change Repurchase Notice”) in the form set forth in the Form of Fundamental Change Repurchase Notice in
Attachment 2 to the Form of Note attached hereto as Exhibit A, if the Notes are Physical Notes, or in compliance with the Depositary’s procedures for surrendering interests in Global Notes, if the Notes are Global Notes, in each case before the
close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date. 

  
 75 












 Each Fundamental Change Repurchase Notice shall state: 

(i)    in the case of Physical Notes, the certificate numbers of the Notes to be delivered for repurchase;

 (ii)    the portion of the principal amount of the Notes to be repurchased, which must be $1,000 or an
integral multiple thereof (provided that any portion of a Holder’s Note not to be repurchased is in the minimum principal amount of $1,000); and 

(iii)    that the Notes are to be repurchased by the Company pursuant to the applicable provisions of the
Notes and this Indenture 
 provided, however, that if the Notes are Global Notes, the Repurchase Notice must comply with appropriate Depositary
procedures. 
 Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change Repurchase
Notice contemplated by this Section 16.01 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close of business on the Business Day immediately preceding the Fundamental
Change Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 16.02. 
 The
Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof. 

Section 16.02.    Withdrawal of Fundamental Change Repurchase Notice. 

(a)    A Fundamental Change Repurchase Notice may be withdrawn (in whole or in part) by means of a written notice of
withdrawal delivered to the Corporate Trust Office of the Paying Agent in accordance with this Section 16.02 at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date specifying:

 (i)    the principal amount of the Notes with respect to which such notice of withdrawal is being
submitted; 
 (ii)    if Physical Notes have been issued, the certificate number of the Note in respect
of which such notice of withdrawal is being submitted; and 
 (iii)    the principal amount, if any, of
such Note that remains subject to the original Fundamental Change Repurchase Notice, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000 (provided that any portion of a Holder’s Note not to be
repurchased is in the minimum principal amount of $1,000); 
 provided, however, that if the Notes are Global Notes, the notice must comply
with appropriate procedures of the Depositary. 
 Section 16.03.    Deposit of Fundamental Change Repurchase
Price. (a) The Company shall deposit with the Trustee (or other Paying Agent appointed by the Company, or if the 

  
 76 












 
Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 4.06(b)) on or prior to 11:00 a.m., New York City time, on the Fundamental Change
Repurchase Date, as the case may be, an amount of money sufficient to repurchase all of the Notes to be repurchased at the appropriate Fundamental Change Repurchase Price. Subject to receipt of funds and/or Notes by the Trustee (or other Paying
Agent appointed by the Company), payment for Notes surrendered for repurchase will be made on the later of (i) the Fundamental Change Repurchase Date with respect to such Note (provided the Holder has satisfied the conditions in
Section 16.01) and (ii) the time of book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the manner required by Section 16.01, by mailing checks for
the amount payable to the Holders of such Notes entitled thereto as they shall appear in the Note Register; provided, however, that payments to the Depositary shall be made by wire transfer of immediately available funds to the account
of the Depositary or its nominee. 
 (b)    If by 11:00 a.m. New York City time, on the Fundamental Change Repurchase
Date the Trustee (or other Paying Agent appointed by the Company) holds money sufficient to make payment on all the Notes or portions thereof that are to be repurchased on such Fundamental Change Repurchase Date then (i) such Notes will cease
to be Outstanding, (ii) interest will cease to accrue on such Notes (whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to the Trustee or Paying Agent) and (iii) all other rights of the Holders
of such Notes will terminate (other than the right to receive the Fundamental Change Repurchase Price). 

Section 16.04.    Repayment to the Company. To the extent that the aggregate amount of cash deposited
by the Company pursuant to Section 16.03 exceeds the aggregate Fundamental Change Repurchase Price of the Notes or portions thereof that the Company is obligated to repurchase pursuant to this Article 16, then promptly after the relevant
Fundamental Change Repurchase Date the Paying Agent shall return any such excess cash to the Company. 

Section 16.05.    Notes Repurchased In Part. Upon surrender of any Note that is to be repurchased only
in part in accordance with Section 16.01, and promptly after the Fundamental Change Repurchase Date, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Note, without service charge, a new Note or
Notes, of such authorized denomination or denominations as may be requested by such Holder (which must be equal to $1,000 principal amount or greater integral multiples of $1,000), 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 16.06.    Covenant to Comply with Applicable Laws Upon Repurchase of Notes. In
connection with any repurchase offer pursuant to this Article 16, the Company shall, if required: 
 (a)    comply with
the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act; 

(b)    file a Schedule TO or any successor or similar schedule; and 

  
 77 












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

MEETING OF HOLDERS OF NOTES 

Section 17.01.    Purposes For Which Meetings May Be Called. A meeting of Holders of
Notes may be called at any time and from time to time pursuant to this Article 17 to make, give or take any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be made, given or taken by

 Section 17.02.    Call
Notice and Place of Meetings. (a) The Trustee may at any time call a meeting of Holders of Notes for any purpose specified in Section 17.01 hereof, to be held at such time and at such place in The City of New York. Notice of
every meeting of Holders of Notes, setting forth the time and the place of such meeting, in general terms the action proposed to be taken at such meeting and the percentage of the principal amount of the then-Outstanding Notes which shall constitute
a quorum at such meeting, shall be given, in the manner provided in the Indenture, not less than 21 nor more than 180 days prior to the date fixed for the meeting.

 Section 17.04.    Quorum; Action. The Persons

notice need be given only once and not less than five days prior to the date on which the meeting is scheduled to be reconvened.

2.875% Convertible Senior Note due 2028 

This Note is one of a duly authorized issue of the Notes of the Company, designated as its 2.875% Convertible Senior Notes due 2028 (herein
called the “Notes”), initially limited to the aggregate principal amount of $373,750,000, all issued or to be issued under and pursuant to an Indenture dated as of April 20, 2021 (herein called the
“Indenture”), between the Company and Wells Fargo Bank, National Association (herein called the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of
the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Notes. Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions
specified in the Indenture. 
 In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the
principal of and accrued and unpaid interest, if any, on all Notes may be declared, by either the Trustee or Holders of not less than 25% in aggregate principal amount of Notes then outstanding, and upon said declaration shall become, due and
payable, in the manner, with the effect and subject to the conditions and certain exceptions set forth in the Indenture. 
 Subject to the
terms and conditions of the Indenture, the Company will make all payments and deliveries in respect of the Fundamental Change Repurchase Price and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a Note to
a Paying Agent to collect such payments in respect of the Note. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. 

The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the Holders of the
Notes, and in other circumstances, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding, evidenced as in the Indenture provided, to execute supplemental indentures modifying
the terms of the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate principal amount of the Notes at the time outstanding may on behalf of
the Holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences. 
 No reference herein
to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (including the Fundamental Change Repurchase Price, if applicable),
and accrued and unpaid interest on, this Note at the place, at the respective times, at the rate and in the lawful money herein prescribed or to satisfy its obligation to convert the Notes.

$1,000. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations 

  
 A-6 












 
provided in the Indenture, Notes may be exchanged for a like aggregate principal amount of Notes of other authorized denominations, without payment of any service charge but, if required by the
Company or Trustee, with payment of a sum sufficient to cover any tax, assessments or other governmental charges that may be imposed in connection therewith as a result of the name of the Holders of the new Notes issued upon such exchange of Notes
being different from the name of the Holder of the old Notes surrendered for such exchange. 
 There will be no sinking fund. 

Upon the occurrence of a Fundamental Change, each Holder shall have the right, at such Holder’s option, to require the Company to
repurchase for cash all of such Holder’s Notes or any portion thereof on the Fundamental Change Repurchase Date at a price equal to the Fundamental Change Repurchase Price. However, a Holder may only require the Company to repurchase fewer than
all of such Holder’s Notes if (i) the principal amount of Notes to be repurchased is an integral multiple of $1,000 and (ii) the portion of such Holder’s Notes not to be repurchased is in a minimum principal amount of $1,000.

 Subject to the provisions of the Indenture, during certain periods and upon the occurrence of certain conditions specified in the
Indenture, the Holder hereof has the right, at its option, prior to the close of business on the second Business Day immediately preceding the Maturity Date, to convert any Notes or portion thereof, into cash, or a combination of cash and shares of
Common Stock at a Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture; provided that a Holder may only convert fewer than all of such Holder’s Notes if (i) the principal amount of
Notes to be converted is an integral multiple of $1,000 and (ii) the portion of such Holder’s Notes not to be converted is in a minimum principal amount of $1,000.
